Power inverter. A power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as.

Power inverter. a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.## Input and output.## Input voltage.A typical power inverter device or circuit requires a stable DC power source capable of supplying enough current for the intended power demands of the system. The input voltage depends on the.

Power inverter. are two basic designs for producing household plug-in voltage from a lower-voltage DC source, the first of which uses a switching boost converter to produce a higher-voltage DC and then converts to AC. The second method converts DC to AC at battery level and uses a line-frequency transformer to create the output voltage.## Square wave.This is one of the simplest waveforms an inverter design can produce and is best suited to low-sensitivity applications such as lighting and heating. Square wave output can produce "humming" when connected to audio equipment and is generally unsuitable for sensitive electronics.## Sine wave.A power inverter.

Power inverter. device that produces a multiple step sinusoidal AC waveform is referred to as a "sine wave inverter". To more clearly distinguish the inverters with outputs of much less distortion than the "modified sine wave" (three-step) inverter designs, the manufacturers often use the phrase "pure sine wave inverter". Almost all consumer grade inverters that are sold as a "pure sine wave inverter" do not produce a smooth sine wave output at all, just a less choppy output than the square wave (two-step) and modified sine wave (three-step) inverters. However, this is not critical for most electronics as they deal with the.

Power inverter. output quite well.Where power inverter devices substitute for standard line power, a sine wave output is desirable because many electrical products are engineered to work best with a sine wave AC power source. The standard electric utility provides a sine wave, typically with minor imperfections but sometimes with significant distortion.Sine wave inverters with more than three steps in the wave output are more complex and have significantly higher cost than a modified sine wave, with only three steps, or square wave (one step) types of the same power handling. Switch-mode power supply (SMPS) devices, such as personal computers or DVD.

Power inverter. players, function on modified sine wave power. AC motors directly operated on non-sinusoidal power may produce extra heat, may have different speed-torque characteristics, or may produce more audible noise than when running on sinusoidal power.## Modified sine wave.The modified sine wave is the sum of two square waves, one of which is delayed one-quarter of the period with respect to the other. The result is a waveform which has voltage steps of zero, peak positive, zero, peak negative and again zero. This voltage value sequence is repeated continuously. The resultant voltage waveform better approximates the shape of a sinusoidal voltage.

Power inverter. entirely without problems, but if the item has a mains transformer, this can overheat depending on how marginally it is rated.However, the load may operate less efficiently owing to the harmonics associated with a modified sine wave and produce a humming noise during operation. This also affects the efficiency of the system as a whole, since the manufacturer's nominal conversion efficiency does not account for harmonics. Therefore, pure sine wave inverters may provide significantly higher efficiency than modified sine wave inverters.Most AC motors will run on MSW inverters with an efficiency reduction of about 20% owing to the harmonic content.

Power inverter. DC supply, in the manner of the MSN designs, but the switching takes place at a far faster rate, typically many KHz, so that the varying width of the pulses can be smoothed to create the sine wave. If a microprocessor is used to generate the switching timing, the harmonic content and efficiency can be closely controlled.## Output frequency.The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.Also, if the.

Power inverter. output of the device or circuit is to be further conditioned (for example stepped up) then the frequency may be much higher for good transformer efficiency.## Output voltage.The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.Some inverters also allow selectable or continuously variable output voltages.## Output power.A power inverter will often have an overall.

Power inverter. battery from the others.## Applications.## DC power source usage.An inverter converts the DC electricity from sources such as batteries or fuel cells to AC electricity. The electricity can be at any required voltage; in particular it can operate AC equipment designed for mains operation, or rectified to produce DC at any desired voltage.## Uninterruptible power supplies.An uninterruptible power supply (UPS) uses batteries and an inverter to supply AC power when mains power is not available. When mains power is restored, a rectifier supplies DC power to recharge the batteries.## Electric motor speed control.Inverter circuits designed to produce a variable output.

Power inverter. voltage range are often used within motor speed controllers.The DC power for the inverter section can be derived from a normal AC wall outlet or some other source. Control and feedback circuitry is used to adjust the final output of the inverter section which will ultimately determine the speed of the motor operating under its mechanical load. Motor speed control needs are numerous and include things like: industrial motor driven equipment, electric vehicles, rail transport systems, and power tools.Switching states are developed for positive, negative and zero voltages as per the patterns given in the switching Table 1. The generated.

Power inverter. gate pulses are given to each switch in accordance with the developed pattern and thus the output is obtained.## In refrigeration compressors.An inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance. Such installations are known as inverter compressors. Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output. The variable-frequency AC from the inverter drives a brushless or.

Power inverter. induction motor, the speed of which is proportional to the frequency of the AC it is fed, so the compressor can be run at variable speeds—eliminating compressor stop-start cycles increases efficiency. A microcontroller typically monitors the temperature in the space to be cooled, and adjusts the speed of the compressor to maintain the desired temperature. The additional electronics and system hardware add cost to the equipment, but can result in substantial savings in operating costs. The first inverter air conditioners were released by Toshiba in 1981, in Japan.## Power grid.Grid-tied inverters are designed to feed into the electric power distribution.

Power inverter. hundred megawatts, are used to deliver power from high voltage direct current transmission systems to alternating current distribution systems.## Solar.A solar inverter is a balance of system (BOS) component of a photovoltaic system and can be used for both grid-connected and off-grid systems. Solar inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.Solar micro-inverters differ from conventional inverters, as an individual micro-inverter is attached to each solar panel. This can improve the overall efficiency of the system. The output from several micro-inverters is then combined and often fed to the electrical.

Power inverter. grid.In other applications, a conventional inverter can be combined with a battery bank maintained by a solar charge controller. This combination of components is often referred to as a solar generator.Solar inverters are also used in spacecraft photovoltaic system.## Induction heating.Inverters convert low frequency main AC power to higher frequency for use in induction heating. To do this, AC power is first rectified to provide DC power. The inverter then changes the DC power to high frequency AC power. Due to the reduction in the number of DC sources employed, the structure becomes more reliable and the output voltage has.

Power inverter. higher resolution due to an increase in the number of steps so that the reference sinusoidal voltage can be better achieved. This configuration has recently become very popular in AC power supply and adjustable speed drive applications. This new inverter can avoid extra clamping diodes or voltage balancing capacitors.There are three kinds of level shifted modulation techniques, namely: Phase Opposition Disposition (POD) Alternative Phase Opposition Disposition (APOD) Phase Disposition (PD)## HVDC power transmission.With HVDC power transmission, AC power is rectified and high voltage DC power is transmitted to another location. At the receiving location, an inverter in a static inverter.

Power inverter. plant converts the power back to AC. The inverter must be synchronized with grid frequency and phase and minimize harmonic generation.## Electroshock weapons.Electroshock weapons and tasers have a DC/AC inverter to generate several tens of thousands of V AC out of a small 9 V DC battery. First the 9 V DC is converted to 400–2000 V AC with a compact high frequency transformer, which is then rectified and temporarily stored in a high voltage capacitor until a pre-set threshold voltage is reached. When the threshold (set by way of an airgap or TRIAC) is reached, the capacitor dumps its.

Power inverter. entire load into a pulse transformer which then steps it up to its final output voltage of 20–60 kV. A variant of the principle is also used in electronic flash and bug zappers, though they rely on a capacitor-based voltage multiplier to achieve their high voltage.## Miscellaneous.Typical applications for power inverters include: Portable consumer devices that allow the user to connect a battery, or set of batteries, to the device to produce AC power to run various electrical items such as lights, televisions, kitchen appliances, and power tools. Use in power generation systems such as electric utility companies or solar.

Power inverter. generating systems to convert DC power to AC power. Use within any larger electronic system where an engineering need exists for deriving an AC source from a DC source. Frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.## Circuit description.## Basic design.In one simple inverter circuit,.

Power inverter. DC power is connected to a transformer through the center tap of the primary winding. A relay switch is rapidly switched back and forth to allow current to flow back to the DC source following two alternate paths through one end of the primary winding and then the other. The alternation of the direction of current in the primary winding of the transformer produces alternating current (AC) in the secondary circuit.The electromechanical version of the switching device includes two stationary contacts and a spring supported moving contact. The spring holds the movable contact against one of the stationary contacts and.

Power inverter. provide large power handling capability in a semiconductor device, and can readily be controlled over a variable firing range.The switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply. Using Fourier analysis, periodic waveforms are represented as the sum of an infinite series of sine waves. The sine wave that has the same frequency as the original waveform is called the fundamental component. The other sine waves,.

Power inverter. car that is moving can turn into a source of energy and can, with the right inverter topology (full H-bridge) charge the car battery when decelerating or braking. In a similar manner, the right topology (full H-bridge) can invert the roles of "source" and "load", that is, if for example the voltage is higher on the AC "load" side (by adding a solar inverter, similar to a gen-set, but solid state), energy can flow back into the DC "source" or battery.Based on the basic H-bridge topology, there are two different fundamental control strategies called basic frequency-variable bridge converter and PWM.

Power inverter. control. Here, in the left image of H-bridge circuit, the top left switch is named as "S1", and others are named as "S2, S3, S4" in counterclockwise order.For the basic frequency-variable bridge converter, the switches can be operated at the same frequency as the AC in the electric grid. However, it is the rate at which the switches open and close that determines the AC frequency. When S1 and S4 are on and the other two are off, the load is provided with positive voltage and vice versa. We could control the on-off states of the switches to adjust the.

Power inverter. AC magnitude and phase. We could also control the switches to eliminate certain harmonics. This includes controlling the switches to create notches, or 0-state regions, in the output waveform or adding the outputs of two or more converters in parallel that are phase shifted in respect to one another.Another method that can be used is PWM. Unlike the basic frequency-variable bridge converter, in the PWM controlling strategy, only two switches S3, S4 can operate at the frequency of the AC side or at any low frequency. The other two would switch much faster (typically 100 KHz) to create square voltages.

Power inverter. level of distortion caused by harmonics. The waveform quality of AC produced directly by H-bridge mentioned above would be not as good as we want.The issue of waveform quality can be addressed in many ways. Capacitors and inductors can be used to filter the waveform. If the design includes a transformer, filtering can be applied to the primary or the secondary side of the transformer or to both sides. Low-pass filters are applied to allow the fundamental component of the waveform to pass to the output while limiting the passage of the harmonic components. If the inverter is designed to.

Power inverter. provide power at a fixed frequency, a resonant filter can be used. For an adjustable frequency inverter, the filter must be tuned to a frequency that is above the maximum fundamental frequency.Since most loads contain inductance, feedback rectifiers or antiparallel diodes are often connected across each semiconductor switch to provide a path for the peak inductive load current when the switch is turned off. The antiparallel diodes are somewhat similar to the "freewheeling diodes" used in AC/DC converter circuits.Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics,.

Power inverter. simplifies the electronics, but the inductors and capacitors tend to be large and heavy. Its high efficiency makes this approach popular in large uninterruptible power supplies in data centers that run the inverter continuously in an "online" mode to avoid any switchover transient when power is lost.A closely related approach uses a ferroresonant transformer, also known as a constant voltage transformer, to remove harmonics and to store enough energy to sustain the load for a few AC cycles. This property makes them useful in standby power supplies to eliminate the switchover transient that otherwise occurs during a power failure while.

Power inverter. size and volume. In 2014, Google together with IEEE started an open competition named Little Box Challenge, with a prize money of $1,000,000, to build a (much) smaller power inverter.## History.## Early inverters.From the late nineteenth century through the middle of the twentieth century, DC-to-AC power conversion was accomplished using rotary converters or motor-generator sets (M-G sets). In the early twentieth century, vacuum tubes and gas-filled tubes began to be used as switches in inverter circuits. The most widely used type of tube was the thyratron.The origins of electromechanical inverters explain the source of the term "inverter". Early AC-to-DC converters.

Power inverter. used an induction or synchronous AC motor direct-connected to a generator (dynamo) so that the generator's commutator reversed its connections at exactly the right moments to produce DC. A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame. The result with either is AC-in, DC-out. With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to.

Power inverter. be "mechanically rectified AC". Given the right auxiliary and control equipment, an M-G set or rotary converter can be "run backwards", converting DC to AC. Hence an inverter is an inverted converter.## Controlled rectifier inverters.Since early transistors were not available with sufficient voltage and current ratings for most inverter applications, it was the 1957 introduction of the thyristor or silicon-controlled rectifier (SCR) that initiated the transition to solid state inverter circuits.The "commutation" requirements of SCRs are a key consideration in SCR circuit designs. SCRs do not turn off or "commutate" automatically when the gate control signal is shut off. They.

Power inverter. only turn off when the forward current is reduced to below the minimum holding current, which varies with each kind of SCR, through some external process. For SCRs connected to an AC power source, commutation occurs naturally every time the polarity of the source voltage reverses. SCRs connected to a DC power source usually require a means of forced commutation that forces the current to zero when commutation is required. The least complicated SCR circuits employ natural commutation rather than forced commutation. With the addition of forced commutation circuits, SCRs have been used in the types of inverter circuits described.

Power inverter. above.In applications where inverters transfer power from a DC power source to an AC power source, it is possible to use AC-to-DC controlled rectifier circuits operating in the inversion mode. In the inversion mode, a controlled rectifier circuit operates as a line commutated inverter. This type of operation can be used in HVDC power transmission systems and in regenerative braking operation of motor control systems.Another type of SCR inverter circuit is the current source input (CSI) inverter. A CSI inverter is the dual of a six-step voltage source inverter. With a current source inverter, the DC power supply is configured.

Power inverter. as a current source rather than a voltage source. The inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform. CSI inverter commutation methods include load commutation and parallel capacitor commutation. With both methods, the input current regulation assists the commutation. With load commutation, the load is a synchronous motor operated at a leading power factor.As they have become available in higher voltage and current ratings, semiconductors such as transistors or IGBTs that can be turned off by means of control signals have become the preferred switching components.

Power inverter. for use in inverter circuits.## Rectifier and inverter pulse numbers.Rectifier circuits are often classified by the number of current pulses that flow to the DC side of the rectifier per cycle of AC input voltage. A single-phase half-wave rectifier is a one-pulse circuit and a single-phase full-wave rectifier is a two-pulse circuit. A three-phase half-wave rectifier is a three-pulse circuit and a three-phase full-wave rectifier is a six-pulse circuit.With three-phase rectifiers, two or more rectifiers are sometimes connected in series or parallel to obtain higher voltage or current ratings. The rectifier inputs are supplied from special transformers that provide phase.

Power inverter. shifted outputs. This has the effect of phase multiplication. Six phases are obtained from two transformers, twelve phases from three transformers and so on. The associated rectifier circuits are 12-pulse rectifiers, 18-pulse rectifiers and so on...When controlled rectifier circuits are operated in the inversion mode, they would be classified by pulse number also. Rectifier circuits that have a higher pulse number have reduced harmonic content in the AC input current and reduced ripple in the DC output voltage. In the inversion mode, circuits that have a higher pulse number have lower harmonic content in the AC output voltage waveform.## Other.

30 St Mary Axe. 30 St Mary Axe (previously known as the Swiss Re Building and informally known as the Gherkin) is a commercial skyscraper in London's primary financial district, the City of London. It was completed in December 2003 and opened in April 2004. With 41 floors, it is 180 (m) tall and stands on the sites of the former Baltic Exchange and Chamber of Shipping, which were extensively damaged in 1992 in the Baltic Exchange bombing by a device placed by the Provisional IRA in St Mary Axe, a narrow street leading north from Leadenhall Street.After plans to build the 92-storey Millennium.

"The Gherkin" nickname was applied to the current building at least as early as 1999, referring to the plan's highly unorthodox layout and appearance.On 10 April 1992, the Provisional IRA detonated a bomb close to the Baltic Exchange, causing extensive damage to the historic building and neighbouring structures. The United Kingdom government's statutory adviser on the historic environment, English Heritage, and the City of London's governing body,.

30 St Mary Axe. the City of London Corporation, were keen that any redevelopment must restore the Baltic Exchange's old façade onto St Mary Axe. The Exchange Hall was a celebrated fixture of the shipping market.English Heritage then discovered that the damage was far more severe than initially thought, and they stopped insisting on full restoration, albeit over the objections of architectural conservationists. The Baltic Exchange and the Chamber of Shipping sold the land to Trafalgar House in 1995. Most of the remaining structures on the Baltic Exchange site were then carefully dismantled, and the interior of Exchange Hall and the façade were preserved,.

The site needed development, was not on any of the "sight lines" (planning guidance requires that new buildings do not obstruct or detract from the view of St Paul's Cathedral dome when viewed from a number of locations around London), and had housed the Baltic Exchange.The plan for the site was to reconstruct the Baltic Exchange. GMW Architects proposed a new rectangular building surrounding a restored exchange: it would.

Mango. A mango is an edible stone fruit produced by the tropical tree "Mangifera indica". It is believed to have originated in the region between northwestern Myanmar, Bangladesh, and northeastern India. "M. indica" has been cultivated in South and Southeast Asia since ancient times resulting in two types of modern mango cultivars: the "Indian type" and the "Southeast Asian type". Other species in the genus "Mangifera" also produce edible fruits that are also called "mangoes", the majority of which are found in the Malesian ecoregion.Worldwide, there are several hundred cultivars of mango.

Eastern carpenter bee. Xylocopa virginica, sometimes referred to as the eastern carpenter bee, extends through the eastern United States and into Canada. They are sympatric with "Xylocopa micans" in much of southeastern United States. They nest in various types of wood and eat pollen and nectar. In "X. virginica", dominant females do not focus solely on egg-laying, as in other bee species considered to have "queens". Instead, dominant "X. virginica" females are responsible for a full gamut of activities including reproduction, foraging, and nest construction, whereas subordinate bees may engage in little activity outside of guarding the nest.## Description and identification.The bee is.

Eastern carpenter bee. similar in size to bumblebees, but has a glossy, mostly black body with a slight metallic purple tint. "X. virginica" males and females have generally the same mass, but can be differentiated visually by the male's longer body and the female's wider head. The males also have a white spot on their face. Additionally, the males have larger thoracic volumes for given masses. Females of different social standing can also be told apart based on morphology. Primary females are larger than secondary or tertiary females, and also have more mandibular and wing wear."X. virginica" have distinctive maxillae that are adapted.

Eastern carpenter bee. to performing perforations on corolla tubes to reach nectaries. Their maxillae are sharp and wedge-shaped, allowing them to split the side of corolla tubes externally to access the nectar. Eastern carpenter bees also have galae on their maxillae that are shaped like large, flat blades. Bees with sharp galae can use these to further aid in penetrating the corolla tubes.## Taxonomy and phylogeny."X. virginica" belongs to the genus "Xylocopa", which consists of over 400 species worldwide, in the subgenus "Xylocopoides", which contains only 5 New World species, including "Xylocopa californica", which also occurs in the U.S.## Distribution."X. virginica" is found.

Eastern carpenter bee. throughout much of North America east of the Rocky Mountains and at least as far north as Nebraska, southern Ontario, and Maine.## Nesting."X. virginica" build their nests in wood, bamboo culms, agave stalks, and other comparable materials, but they prefer to nest in milled pine or cedar lumber. The nests are built by scraping wood shavings off of the wall. These shavings are then used to create partitions between nesting cells. The entrance cuts into the wood perpendicular to the grain, but they are built parallel beyond the entrance. These nests may be either social, containing groups of two to.

Eastern carpenter bee. five females, or solitary. Social nests are more common, despite the fact that brood productivity is actually lower when females choose to nest together. Because "X. virginica" builds its nests in wood structures, it is common for it to nest in constructed furniture or buildings. "X. virginica" is the most common large carpenter bee in eastern North America, and it nests in small groups, so nests are fairly commonly encountered.The nests are usually round and typically have one to four tunnels. They have multiple branches, with each adult female living and laying eggs in a separate branch but females sharing.

Eastern carpenter bee. one common entrance. Because the nests are costly to build, it is common for females to reuse old nests.## Life cycle.In "X. virginica," mating occurs only once a year, in the spring. Eggs are laid in July, starting farthest from the exit hole, and by about August and mid-September, larval development has completed and all the pupae have become adults. Researchers suggest that there is a mechanism that synchronizes the emergence time of young that are laid at different times by causing the younger eggs to develop faster. This mechanism prevents bees that would emerge sooner from removing their siblings.

Eastern carpenter bee. and decreasing their potential competition.Bees that have newly emerged have a soft cuticle and white wings. The wings later transition to brown, then to a bluish black. They can fly 3–4 days after emergence, but they remain in their nest for at least two weeks, consuming nectar but not pollen. The juveniles begin the next mating cycle the following spring, so one generation develops in a year.Females begin to exhibit signs of senescence around July. The indicative behavior includes resting in flowers, remaining in the nest, or even just falling to the ground from flight. Older individuals also crawl, avoid.

Eastern carpenter bee. taking flight, and do not struggle when handled by humans. The old bees die by early August, the same time that juveniles emerge from brood cells. Due to the simultaneous nature of expiration of old bees and emergence of new ones, there is little overlap between generations, except for some females that survive a second winter.## Behavior."X. virginica" is not a solitary bee species, but it is not truly social either. The weak form of sociality they exhibit, with one female doing the majority of the work and caring for her sisters, may be a transitional step in the evolution.

Eastern carpenter bee. of sociality.## Dominance hierarchy.Female "X. virginica" can have solitary nests, but they usually nest in social groups. The social order of "X. virginica" is broken into three groups: primary, secondary, and tertiary. Primary females act as the dominant within a nest and are in charge of reproduction, providing food for the larvae, and laying all the eggs. This is different from many bee species in which there is a queen that focuses her energy solely on laying eggs while relying on provisions provide by subordinate bees. Secondary females may sometimes participate in oviposition, and they reinforce this potential role by.

Eastern carpenter bee. helping provide for the larvae or performing nest maintenance. Tertiary females rely on the provisions provided by primary females and quietly await overwintering while remaining inactive.Studies have shown that primary females are usually the bees that have overwintered twice, while tertiary bees have only overwintered once. Tertiary bees will most likely survive a second overwintering and develop further to become primary female the following year. Secondary bees may survive a second winter, but that is unlikely if they actively forage after their first overwintering.## Division of labor among the sexes.Not all females do the same work in a social nest.

Eastern carpenter bee. This is evident based on the varying levels of wear on the wings and mandibles of females of various social standing. Although many nests have more than one female, there is a division of labor between the older and younger females. During nesting time, only the older females are responsible for nesting duties such as digging, excavating the cells, lining the cells, collecting food, and ovipositing. Evidence of this activity can be found in their worn mandibles. Young females rarely leave the nest and guard the entrance while the older females work, resulting in unworn wings and mandibles in the.

Eastern carpenter bee. younger females. Additionally, "X. virginica" is the only known species in which one-year-old females cohabit the nest with two-year-old females that do all the labor.Males often spend long periods of time hovering, flying, or in fast pursuit of intruders, while female flight activity is usually very directed, such as flights to flowers and food sites. Larger females have an advantage because they can carry larger amounts of pollen or nectar back to the nest and can fly longer distances.## Diet."X. virginica" survive mostly on nectar and pollen. Newly emerged bees do not have food stored in their nest, but they.

Eastern carpenter bee. are occasionally brought nectar. "X. virginica" use their maxillae to penetrate the corolla of plants and reach the nectar stores, a behavior known as nectar robbing. This happens when the bee pierces the corollas of long-tubed flowers, thus accessing nectar without making contact with the anthers and bypassing pollination. In some plants this reduces fruit production and seed number. In other plants, defensive mechanisms allow pollination to occur despite perforation of the corolla.## Mating behavior.Each nest usually has one mated individual. Mating occurs in April and is often accompanied by a bobbing dance that involves about a dozen males and.

Eastern carpenter bee. only a few females.Males require female activity, specifically flight, in mating. Occasionally before mating, the couple will face each other and hover for a few minutes. When the male contacts the female, he mounts her back and attempts to push his abdomen under hers. Copulation then occurs, and it is almost always followed by more mating attempts. If, during copulation, the female lands, the couple will disengage and the male will hover waiting for the female to take flight again; however, although the males almost always disengage and pause copulation when the female lands, there have been instances recorded in.

Eastern carpenter bee. which the males will hold on to the female with all six legs and flap his wings in an attempt to lift her back into the air.Larger males are usually more successful in mating. Because of their competitive advantage due to their size, males will likely claim a territory near female nest sites. Smaller males will stay at foraging sites or other areas they think females may pass so they can mate with reduced competition.## Kin selection.Research has shown that, regardless of sex, "X. virginica" show more aggression toward non-nestmates than nestmates, indicating that they can recognize each other. By.

Eastern carpenter bee. living in social groups with inclusive fitness, the bees can raise offspring with the help of the nest community rather than as a solitary effort.The ability of "X. virginica" to recognize nestmates allows primaries and secondaries to exclude tertiary bees from their nests. Tertiary bees are a burden on resources because they do not perform any useful activities, but they benefit from the food and shelter provided by the primary females.## Defense.## Territorial behavior in males.Males will establish territories near an active nest entrance to protect the colony and seek mating opportunities. For males that are near the nest entrance,.

Eastern carpenter bee. their boundaries are usually linear and several meters long. For males that are farther from the exit, their boundaries are usually in the shape of a square and shorter in length. Males can stay in one territory for as long as two weeks. Although they do most of their foraging and resting during the night, they take small breaks throughout the day as well. After these breaks, they often have to fight off intruders that have taken advantage of their absence.Flights near the nest are usually uniform and involve much hovering. Flights protecting a bee's territory can be as short.

Eastern carpenter bee. as a few minutes, but may extend beyond an hour. Males will not react to another bee unless the other is flying at high speed. When other individuals hover near the nest, it is unlikely that the male will pursue, whereas if another male comes into a territory at a high speed, the territorial male will give chase. When males patrolling the entrance of a nest are confronted with either dead or living Eastern carpenter bees suspended from a thread and dangled within the male's territory, the male does not respond when the bee is suspended and motionless, whether it.

Eastern carpenter bee. is living or dead—even though "X. virginica" are capable of recognizing other individuals of their species. However, when the suspended bee is released and allowed to fly in the male's territory or is swung through the territory on the thread, the territorial male pursues it.## Parasites.There is one common species of bombyliid flies known to parasitize the larvae of "Xylocopa virginica": "Xenox tigrinus".## Marking.Eastern carpenter bees have mandibular glands that are known to produce a marking chemical in "X. hirsutissima" that functions as a nest marker or for female attraction. The glands are present in both males and females, but.

Eastern carpenter bee. they produce no marking substance. However, "X. virginica" does have a Dufour's gland that is used to deposit a scent on a flower immediately following nectar collection. The scent, composed of hydrocarbons and esters, discourages "X. virginica", as well as other bee species, from returning to that same flower.## Stinging.The male bee is unable to sting because the stinger is simply a modified ovipositor (which males lack by definition), though they will commonly approach human beings and buzz loudly around them or fly close to them. The female, on the other hand, is capable of stinging; while the pain level.

Eastern carpenter bee. of these stings is not well-documented, researchers have testified that "X. virginica" will sting if roughly handled. As the stinger is not barbed, a female can sting multiple times.## Human importance.## Agriculture."X. virginica" visits many different kinds of flowers in order to gather pollen and nectar to bring back to the nest for larvae. Most of the plants they visit are wild grown or grown for decorative value; however, they can be good pollinators of blueberry crops. Their active seasons are quite long, and they forage on a wide variety of plant species. Also, because the start of their activity.

Eastern carpenter bee. season is dependent on temperature, it is easy for greenhouse workers to manipulate the beginning of foraging activity. However, in comparison to species such as the honey bee, their smaller nest makes them less powerful as pollinators.## Destructive behavior.Because "X. virginica" builds its nests in various types of wood, it presents the disadvantage of weakening wood in manmade structures. They are also able to produce an excrement upon exiting their tunnels that may splash on the sides of buildings and negatively affect the aesthetic appeal of that structure. However, when weighed against the benefits "X. virginica" have as pollinators, the.

Eastern carpenter bee. costs of its destructive behavior are insignificant. "X. virginica" offer benefits in the form of pollination for fruits, vegetables, legumes, and flower crops. Although the pollination strengths of "X. virginica" are secondary to that of the bumblebees and honey bees, the contribution is great enough to overlook destructive tendencies. "X. virginica" avoid entrances that are stained white, which is a possible solution to keeping them out of unwanted areas. Mitchell, Theodore B. (1962): Bees of the Eastern United States.

Confederation Bridge. The Confederation Bridge () is a box girder bridge carrying the Trans-Canada Highway across the Abegweit Passage of the Northumberland Strait, linking the province of Prince Edward Island with the province of New Brunswick on the mainland. Opened May 31, 1997, the 12.9 (km) bridge is Canada's longest bridge and the world's longest bridge over ice-covered water.Construction took place from October 1993 to May 1997 and cost C$1.3 billion. Before its official naming, Prince Edward Islanders often referred to the bridge as the "Fixed Link". It officially opened to traffic on May 31, 1997. In April 2022, the PEI legislature.

Automobile service was added in 1938 and other vessels followed as the ferry service expanded in the post-war years.This ferry service was initially the responsibility of Canadian Government Railways (1917–1918) and later Canadian National Railway (1918–1983), then a CNR subsidiary CN Marine (1977–1986). In 1986, CN Marine was renamed when all federal government ferry services in Atlantic Canada were transferred to the new Crown corporation Marine Atlantic.Ferry service years "Scotia I" (various years 1917–1957) "Scotia II" (various years 1937–1968) "Charlottetown" (1931–1941) "Abegweit" (1947–1982), renamed "Abby" (1983–1986) "Confederation" (1962–1976) "John Hamilton Gray" (1968–1997) "Lucy Maud Montgomery.

Howlan also raised the issue as a member of the provincial Legislative Assembly, and in 1891, as a Senator and member of a delegation to meetings on the subject, conducted at the British Parliament. The idea lost favour following his death in 1901.Talk of a fixed link was revived in.

Confederation Bridge. or the private operation of such a crossing;"## Construction.The construction, which was carried out by a construction joint venture of Ballast Nedam, GTMI (Canada), Northern Construction and Strait Crossing Inc., started in the fall of 1993, beginning with preparation of staging facilities. Bridge components were built year-round from 1994 to the summer of 1996, and placement of components began in the fall of 1994 until the fall of 1996. Approach roads, toll plazas, and final work on the structure continued until the spring of 1997, at an estimated total cost of $1 billion.All bridge components were constructed on land, in.

The economic impact of construction on Prince Edward Island was substantial, with the provincial GDP rising over 5% during the construction, providing a short-term economic boom for the Island.It neared completion in April 1997.## Naming.Throughout construction, the federal government received suggestions for names. A committee was formed on.

Confederation Bridge. May 1, 1996, chaired by former PEI Premier Alex Campbell, to choose the new name from the submissions. The committee chose the name "Abegweit Crossing", which would pay homage to the Abegweit Passage which the bridge crosses, the vessel M/V "Abegweit" which the bridge would replace, and to the Mi'kmaq traditional name for the island.However, the Canadian government overruled the committee, and on September 27, 1996, the Minister of Public Works and Government Services Diane Marleau announced that the bridge's name would be "Confederation Bridge". This name is not without controversy as many Islanders feel the word "Confederation" is overused.

Confederation Bridge. throughout the province, finding use in the name of a Northumberland Ferries Limited vessel (M/V "Confederation"), a performing arts centre and art gallery (Confederation Centre of the Arts), a shopping centre (Confederation Court Mall), and the province-wide rails to trails system (Confederation Trail), as well as in tourism promotions (e.g., "Birthplace of Confederation").The President of Ireland, Mary McAleese, during a state visit to Canada in 1998, referred to the bridge as the "Span of Green Gables".## Finishing.After completing the structure on November 19, 1996, SCI worked throughout the winter, paving the bridge deck, placing bridge concrete barrier guardrails which also.

In separate construction, the federal and provincial governments built a new commercial and tourist development on the abandoned CN rail yards in Borden-Carleton, with phase I of this facility opening in spring 1997 as "Gateway Village". New Brunswick has never received similar federal support to improve the economy of Cape Tormentine, which has become a shadow of its former role in PEI transportation history, although in recent years a new eco-tourist and visitor centre.

It is estimated that almost 75,000 people participated in a "Bridge Walk" and "Bridge Run" during the hours immediately prior to.

Laetiporus gilbertsonii. Laetiporus gilbertsonii is a species of polypore fungus in the family Fomitopsidaceae. It is found in western North America. It was one of three new "Laetiporus" species published in 2001, which were distinguished genetically from the common "Laetiporus sulphureus"; the others were "L. conifericola" and "L. huroniensis". The type collection, made in San Francisco's Golden Gate Park in 1997, was found fruiting on a eucalyptus tree. It has also been collected in Oregon and Washington. The fungus is named in honor of mycologist Robert Lee Gilbertson. "L. gilbertsonii" is edible, although some people have reported experiencing upset stomach after consuming.

Laetiporus gilbertsonii. it. "Laetiporus conifericola" is very similar in appearance, but is readily distinguished by its growth on conifers.

Seven Wonders of the Ancient World. The Seven Wonders of the Ancient World (also known as the Seven Wonders of the World or simply the Seven Wonders) is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC.While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located.

Seven Wonders of the Ancient World. in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, with the others being destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. ## Background.Alexander the Great's conquest of much of the western world in the 4th century BC gave Hellenistic travellers access to the civilizations of the Egyptians, Persians, and Babylonians. Impressed and captivated by the landmarks.

Seven Wonders of the Ancient World. including six of the present list (substituting the walls of Babylon for the Lighthouse of Alexandria):Another 2nd century BC writer, who, perhaps dubiously, identified himself as Philo of Byzantium, wrote a short account entitled "The Seven Sights of the World". The surviving manuscript is incomplete, missing its last pages. Still, from the preamble text, we can conclude that the list of seven sights exactly matches Antipater's (the preamble mentions the location of Halicarnassus, but the pages describing the seventh wonder, presumably the Mausoleum, are missing).Earlier and later lists by the historian Herodotus ( BC– BC) and the poet Callimachus of.

Seven Wonders of the Ancient World. with the exceptions being the Pyramids of Giza and the Hanging Gardens of Babylon.## Influence.## Arts and architecture.The seven wonders on Antipater's list won praises for their notable features, ranging from superlatives of the highest or largest of their types, to the artistry with which they were executed. Their architectural and artistic features were imitated throughout the Hellenistic world and beyond.The Greek influence in Roman culture, and the revival of Greco-Roman artistic styles during the Renaissance caught the imagination of European artists and travellers. Paintings and sculptures alluding to Antipater's list were made, while significant numbers of adventurers travelled to.


Question: What is the spore print color of this plant?

Astraeus hygrometricus. common in temperate and tropical regions. Its common names refer to the fact that it is hygroscopic (water-absorbing), and can open up its rays to expose the spore sac in response to increased humidity, and close them up again in drier conditions. The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the spores mature. The spores are reddish-brown, roughly spherical with minute warts, measuring 7.5–11 micrometers in diameter.Despite a similar overall appearance, "A.

Astraeus hygrometricus. interior of the spore case, the gleba, is white and solid when young, and divided into oval locules—a characteristic that helps to distinguish it from "Geastrum". The gleba becomes brown and powdery as the specimen matures. Small dark hairlike threads (rhizomorphs) extend from the base of the fruit body into the substrate. The rhizomorphs are fragile, and often break off after maturity.The spores are spherical or nearly so, reddish-brown, thick-walled and verrucose (covered with warts and spines). The spores' dimensions are 7–11 µm; the warts are about 1 µm long. The spores are non-amyloid, and will not stain with iodine.

Astraeus hygrometricus. moist soil. The spore ornamentation of "A. odoratus" is also distinct from "A. hygrometricus", with longer and narrower spines that often joined. "A. asiaticus" has an outer peridial surface covered with small granules, and a gleba that is purplish-chestnut in color, compared to the smooth peridial surface and brownish gleba of "A. hygrometricus". The upper limit of the spore size of "A. asiaticus" is larger than that of its more common relative, ranging from 8.75 to 15.2 μm. "A. koreanus" (sometimes named as the variety "A. hygrometricus" var. "koreanus"; see Taxonomy) differs from the more common form in its smaller.

The Exchange Hall was a celebrated fixture of the shipping market.English Heritage then discovered that the damage was far more severe than initially thought, and they stopped insisting on full restoration, albeit over the objections of architectural conservationists. The Baltic Exchange and the Chamber of Shipping sold the land to Trafalgar House in 1995. Most of the remaining structures on the Baltic Exchange site were then carefully dismantled, and the interior of Exchange Hall and the façade were preserved,.
