Since chemosensory genes play key roles in insect behaviour, they can potentially be used as new targets for pest control. The cabbage beetle, Colaphellus bowringi, is a serious insect pest of cruciferous vegetables in China and other Asian countries. However, a systematic identification of the chemosensory genes expressed in the antennae has not been reported. We assembled the antennal transcriptome of C. bowringi by using Illumina sequencing technology and identified 104 candidate chemosensory genes by analyzing transcriptomic data, which included transcripts encoding 26 odorant-binding proteins (OBPs), 12 chemosensory proteins (CSPs), four sensory neuron membrane proteins (SNMPs), 43 odorant receptors (ORs), nine ionotropic receptors (IRs), and ten gustatory receptors (GRs). The data obtained are similar to those found in other coleopteran species, suggesting that our approach successfully identified the chemosensory genes of C. bowringi. The expression patterns of 43 OR genes, some of which were

Olfaction presents the ultimate challenge to molecular recognition as thousands of molecules have to be recognized by far fewer olfactory receptors. We have presented evidence that Drosophila readily distinguish odorants based on their molecular vibrations using a battery of behavioral assays suggesting engagement of a molecular vibration-sensing component. Here we interrogate electrophysiologically the antennae of four Drosophilids and demonstrate conserved differential response amplitudes to aldehydes, alcohols, ketones, nitriles and their deuterated isotopologues. Certain deuterated odorants evoked larger electroantennogram (EAG) amplitudes, while the response to the normal odorant was elevated in others. Significantly, benzonitrile isotopologues were not distinguishable as predicted. This suggests that isotopologue-specific EAG amplitudes result from differential activation of specific olfactory receptors. In support of this, odorants with as few as two deuteria evoke distinct EAG amplitudes ...

An ablation treatment apparatus has a multiple antenna device with a primary antenna and a secondary antenna. The secondary antenna is positioned in a lumen of the primary antenna as the primary antenna is introduced through tissue to a selected tissue site. At the tissue site the secondary antenna is deployed from the primary antenna in a lateral direction relative to a longitudinal axis of the primary antenna. At least a portion of a distal end of the secondary antenna is structurally less rigid than the primary antenna. The primary antenna is constructed to be rigid enough to be introduced and advanced through tissue. A cable couples the energy source to one or more of the antennas.

I live in the centre of a seaside town in the UK. Because of lack of space I have a random wire antenna in the loft of a small house, and pick up a lot of noise on the top band Sunday morning CW ragchew. I am about twenty hilly miles from most of my friends and the noise overwhelms many of their signals. I have a Maplin Super Scan Mk2 all band vertical antenna with a built in amplifier chip, which I have never used. I would like to try mounting the Maplin antenna on a pole a few feet above the roof to see if I can cut down the noise on reception. Normally I run 25 Watts on transmission.. My rig is an Elecraft K2 with KPA100, which has a separate dedicated receive antenna socket, so no RF will be transmitted directly into the Maplin antenna.. So, my question is: is the RF from my own transmission into the loft antenna likely to damage the nearby Maplin antenna internal amplifier chip during my tests?. ...
Here is the practical method. I just scribbled it on my iPad. You may download it as a PDF file. :-) - Thierry. Thierry, I have seen something similar to this (The EPE-2008 theremin had a on-board circuit to assist tuning) - but, in playing with the EPE circuit, I found the operation of this circuit unsatisfactory.. My understanding (and my experiments) indicate that maximum loading on the oscillator occurs at the resonant frequency of the antenna circuit (coils + antenna capacitance).. and that one wants the hand capacitance seen by the antenna to be at the position one requires for the null point (about 60cm from the antenna). The resistance inserted between the oscillator and antenna circuit allows the oscillator frequency to be adjusted without being effected by the antenna loading - so one can find (by looking for peak current) the resonant frequency of the antenna circuit.. However, as soon as the 100k (or whatever value is used to isolate the antenna from the oscillator) is replaced ...

An electrical device configured to install within a wall mounted electrical box includes an antenna bezel frame, an antenna element, and a radio frequency circuitry component. At least a portion of the antenna bezel frame is configured to protrude through an opening in a faceplate. The antenna element is mounted to the antenna bezel frame such that the antenna element is located a distance forward of a plane that contains a front surface of the faceplate when the field configurable electrical device is installed. The radio frequency circuitry component is in electrical communication with the antenna element and is configured to receive a control signal from the antenna element.
The idea behind the quarter wavelength antenna is that it is self-resonant: it is tuned. You can however use an antenna of any size to pick off some electromagnetic energy - and you can tune the antenna by adding some inductance in series (or inductance and capacitance). The reason that you tune an antenna is simply this: you want it to have real impedance, which happens exactly at resonance. When this happens, then all the power that is incident on the antenna ends up going into the electronics; when the impedance is complex, the current either lags or leads the voltage, and this results in reflection of the power (and less power going into the amplifier). You cant get around the fact that you are capturing energy from less area in space, so it will be less efficient. On the other hand having an antenna that is too long doesnt buy you anything as the signal from one part of the antenna would cancel the signal from another.. This is one of the beautiful things about the Yagi antenna: the ...

A passive reflective antenna located near an active receiving antennas is used to change the energy at the receiving antenna. The change in energy may be such as to remove a null created by multipath or to provide directionality, or both. The receiving antennas is permanently connected to a single receiver. When the receivers output signal degrades below an acceptable level of quality, the reflective phase of the passive antennas load is changed to change the phase of the reflected energy and achieve a desired effect (remove a null, change directionality, etc.) at the receiving antenna. In the simplest embodiment, the termination of the passive antenna is switched from an open circuit to a short circuit, or vice versa, to invert the phase of the reflected energy. The use of reflective elements in antenna designs, usually to achieve directionality, is well known (see the common Yagi or corner reflector antenna designs, for example), but these use passive reflector elements.

The antennal lobe is the deutocerebral neuropil of insects which receives the input from the olfactory sensory neurons on the antenna. Functionally, it shares some similarities with the olfactory bulb in vertebrates.. In insects, the olfactory pathway starts at the antennae (though in some insects like Drosophila there are olfactory sensory neurons in other parts of the body) from where the sensory neurons carry the information about the odorant molecules impinging on the antenna to the antennal lobe.[1] The antennal lobe is composed of densely packed neuropils, termed glomeruli, where the sensory neurons synapse with the two other kinds of neurons, the projection neurons and the local neurons.[1] There are 43 glomeruli in the Drosophila antennal lobe; in Aedes aegypti there are 32;[1] locusts and social wasps may have over 1000.[1] The projection neurons project to higher brain centers such as the mushroom body and the lateral horn.[2] [3] [4] The local neurons, which are primarily inhibitory, ...
We conducted Ribonucleic Acid sequencing analysis of the codling moth antennal transcriptome and identified 66 odorant receptors (ORs) in a population from Xinjiang province, China; of which 14 were PRs, including two novel PRs (CpomOR2e and CpomOR73). Sex pheromones that in most cases attract males to virgin females have been the most extensively used in IPM, especially with lepidopteran pests. Typical alarm behavior is produced also by homologous 2-alkanones with a chain length of 6-9 carbon atoms. Pheromones are released by insects and other organisms into the environment in order to communicate with others of the same species. The transmission of information by insects is carried out with the help of special odorous substances called pheromones, SUMMARY1 Chemical communication plays an important part in the lives of insects, and particularly in lives of those that live in groups or social organizations.

A system and method are described for using RFID tags to track and monitor personnel and equipment in large environments and environments that are prone to multipath fading. The system scans the environment by selecting local interrogation zones where RFID tags may be located. Multiple antennae are used, each transmitting a portion of an activation signal, such that the activation signal will be formed in the selected local interrogation zone. Different subsets of the antennae are successively selected, each targeting the selected local interrogation zone, to repeat the activation signal for each subset of antenna. RFID tags in the local interrogation zone will receive the portions of the activation signals and process them to determine whether the full activation signal was destined for that local interrogation zone for each of the subsets of antennae. An activated RFID tag will transmit its tag information, including any data collected from sensors connected to the tag, back to the system. The systems
An antenna circuit to be used in conjunction with a chip transponder such that the antenna circuit serves for both the reception of interrogative signals intended for the transponder as well as for response signals that ape to be transmitted by the transponder. The antenna circuit has at least one magnetic circuit of high μ material, and is formed of ceramic core means, that have been built into a depression in a thick-walled surface intended to receive the chip transponder. This thick-walled surface may be of metal. The ceramic core means comprise at least a ceramic core resonator and half a ceramic core that functions as an antenna with its open side facing outward. In one aspect, the ceramic core resonator and the half ceramic core antenna are coupled by means of one or more secondary coils of the closed ceramic core, which also form the coils of the half ceramic core antenna. In another aspect, the secondary coil forms a resonating circuit with at least one capacitive element in series. In yet
Cigarette and drugstore beetles are often confused with one another. Adult beetles are rounded in profile, oval shaped, light-brown color, 1/16-1/8 inch-long. A hood-like shield (prothorax) encloses and conceals the head when viewed from above. The femora of each hind leg retracts into a groove in hind coxa. These beetles can be distinguished by the grooving on the wing covers and by their antennal shape. The drugstore beetles wing covers possess distinct striae, or grooves, and its antennae are clubbed with three elongated and broadened segments at the tips. The wing covers of cigarette beetles are very smooth, without distinct grooves; and the antennal segments are sawlike, or serrate.

Citation: Byers, J.A. 2013. Modeling and regression analysis of semiochemical dose-response curves of insect antennal reception and behavior. Journal of Chemical Ecology. 39(8):1081-1089. Interpretive Summary: Semiochemicals are released by organisms that when perceived by another organism cause it to change behavior. Insects use semiochemicals for communication, to find mates, or to locate or assess host plants. Many insect species have been studied to determine the relationship between concentration (dose) of a specific semiochemical and the corresponding insect behavioral response. Although it is generally recognized that these dose-response relationships are not linear, little information exists to indicate the true functional relationship between semiochemical dose and insect response. A computer simulation using a hypothetical insect antenna and a wide range of semiochemical doses indicated a family of mathematical equations, or functions, described the dose-response relationship nearly ...
Other notes: The rare metallic blue form can be confused with P. cochleariae. However, in P. concinnus, the antennae are entirely black; in P. cochleariae, the underside of the 2nd & 3rd antennal segments are reddish (or at least with a reddish spot ...
A device and method is disclosed for creating a lesion in nerve-containing tissue spaced from a body lumen while protecting tissue forming and adjacent to a wall of the body lumen from injury. A catheter carrying a microwave antenna is positioned within the body lumen. Cooling fluid is circulated around the microwave antenna in thermal contact with the wall of the body lumen. Power is supplied to the microwave antenna to cause microwave energy to be emitted omnidirectionally from the microwave antenna. The power supplied to the microwave antenna and the cooling fluid circulated around the microwave antenna are controlled to cause the nerve-containing tissue spaced from the body lumen to be heated to a temperature sufficient to cause thermal damage while the tissue forming and adjacent to the wall of the body lumen is maintained at a temperature where thermal damage does not occur.
The other problem is the science. Every year we are told that eating foods containing nutrient X is really, really, bad for us, and its a wonder our ancestors survived long enough to reproduce. And then a year or two later, we find out that, fancy that, nutrient X is actually necessary for optimal functioning and we have to start adding it back in. This years must eat food also turns out to be next years you-really-need-to-cut-back-on food. Look at butter vs. margarine. Unless you have a lactose issue, butter has no more calories, and not having tons of weird chemicals, its much, much healthier. I admit we still have some I cant believe its not butter or some Olio in the fridge, but thats because its so much easier to spread than butter. But we dont use much, and I do all my cooking with lots of butter. I eat lots of meat, and Im discovering that as I cut carbs, the fat is actually starting to taste really good. And guess what?

Bristletails are primitive wingless insects. At first glance they resemble silverfish, however silverfish have three abdominal filaments nearly equal in length. In bristletails, the central filament is much longer than the side two. Unlike silverfish, bristletails have well developed compound eyes. The compound eyes are large and meet on the back of the head. Three simple eyes (ocelli) also occur on bristletails. Bristletails have well developed mandibles which are partially hidden in the head. The antennae are long and resemble a chain of beads (moniliform). Bristletails are usually nocturnal and have an interesting habit of arching and flexing the body to give a springing action similar to springtails. Bristletails are found in litter, moss, lichens and other similar habitats ...

A stacked patch antenna has a first element having a feed thereto spaced above a ground plane and one or more spaced apart parasitic elements spaced above the first element. The first and parasitic elements may be tuned to a fundamental mode for radiation of a specified frequency. The geometric centers of the parasitic elements are offset from one another and from the geometric center of the first element along the same direction. The stacked patch configuration provides increased gain and bandwidth. The offset configuration determines the direction of maximum gain for the antenna. The first and parasitic elements can be single antenna elements and may be microstrip antenna elements. The elements can also be arrays of microstrip antenna elements. The phasing of the arrays of microstrip elements can be controlled to determine a gain sensitivity direction.
A helical antenna for use with small portable wireless devices as disclosed which includes a magnetic tuner including a magnet adapted to move in a direction substantially perpendicular to the longitudinal axis of the antenna whereby the impedence of the antenna can be varied greatly by displacement of the magnet only a short distance. The antenna preferably further includes a variable capacitor for reducing any mismatching between the input impedence of the antenna and the characteristic impedence of an associated feeder which can be caused by adjusting the magnetic tuner.

The next morning I had everything hooked up again in the same spot at the Forest Preserve (located in a suburb of Northern Illinois). I moved the Cross Country Preselector to be directly connected from the roof, then to the antenna switch on the Breadboard (see part 2) to better prevent overloading. I turned on the Verizon battery pack and nothing. No Pre-amp light. Switched it on, off, on, off - nothing. So, I thought I must have burnt it out the previous session?. Later on, I found it was some sort of short in the switch and I will have to move the D-cell batteries to a backup battery pack. In the meantime, I had to do without the Pre-amp and was forced to extend the MFJ antenna all the way. With the 18 inch extension attached to the magnet mount, that was a total of 18.5 feet from antenna tip to the top of my car roof.. This was actually fortuitous since I was already concerned about overloading the Pre-amp or perhaps amplifying background noise. This forced me to test it in a more ...

It looks like Dell has messed up the TV Tuner integration into Dell Mini 10 netbooks according to reports from the MyDellMini forums. The option for an internal TV tuner costs $50 and only recently went on sale. However, the first owners to receive their TV-equipped Mini 10s are not a happy bunch.. Users are reporting about not being able to receive any channels from the internal antenna. Frustrated users are reporting that Dell support has so far not been able to give any useful response as to when this issue will be sorted. Whilst an external antenna would make a difference, Dell didnt include one in the box. This is despite showing off the antenna at a recent press event as pictured above. To be fair to Dell, the TV Tuner listing on the website never suggested that an external antenna would be included in the package. However, Dell should at least be offering an upgrade to purchase this part if needed. Update: Dell has rectified this mistake and has now sent out an email to say that they ...
Consider that you may have a card putting 15dBm (32mW) into a 2.2dBi antenna (on the AP), and thatyour card probably has an effective 2dBi gain antenna on it. Operating at 2.4GHz, at 1m, thereis 41dB of path loss between the two units. At 2m, youll have another 6dB of path loss, for 47dB.So the signal leaves at 17dBm (from the AP), you lose 41dB due to LOS (Line of Sight) path lossat 1m, and the signal arrives at the antenna in your laptop at perhaps -24dBm, and is raisedto -22dBm by the antenna.This is quite close to the maximum signal level of 802.11g ...

  • Arthropods make up to 75% of the animals on Earth and they play a key role in maintaining the ecosystem as pollinators, nutrient recyclers, scavengers, and food for other creatures. (beinghuman.org)
  • The arthropods make up the largest group of animals on earth. (beinghuman.org)
  • The incredible diversity and success of the arthropods is because of their very adaptable body plan. (shapeoflife.org)
  • Arthropods have well-developed physiological systems, a distinct head and well-developed central nervous system as well as keen senses of vision, smell and touch. (dtmag.com)
  • In the arthropod body, a central cavity, called the hemocoel (or blood cavity), is present, and the hemocoel fluids are moved by contraction of regions of the tubular dorsal blood vessel called "hearts. (unizin.org)
  • Detrás de la aleta dorsal, las orcas tienen una mancha gris en forma de silla de montar. (hww.ca)
  • Ticks are the principal arthropod vectors of many prevalent zoonotic diseases in North America, including Lyme disease, anaplasmosis, and babesiosis [ 1 , 2 ]. (plos.org)
  • The largest group of arthropods are insects, and they can be distinguished from other arthropods through specific characteristics. (dimensions.com)
  • These characteristics include them having 3 body regions, 3 pairs of legs, as well as a pair of antennae. (dimensions.com)
  • An extensive cladistic analysis resolved Kootenichela as sister-taxon to the enigmatic Worthenella cambria from the middle Cambrian (Series 3, Stage 5), Burgess Shale Formation in Yoho National Park (British Columbia), which is herein reinterpreted as a megacheiran arthropod. (bioone.org)
  • This family occupies a basal position within a paraphyletic Megacheira, the immediate outgroup of Euarthropoda (crown-group arthropods). (bioone.org)
  • The arthropods form the largest group in the animal kingdom and can be recognized by the following characters. (researchgate.net)
  • And just like those vertebrates, insects are just part of a much bigger group that is called Arthropods. (pinayhomeschooler.com)
  • What is the largest group of arthropods? (dimensions.com)
  • The discovery was published this summer in BMC Evolutionary Biology and is one of the latest examples of a growing body of research opening new avenues in how scientists understand the early evolution of arthropods, all of it made possible by the use of the imaging technique called micro-computed tomography, or micro-CT. (harvard.edu)
  • Snowy tree crickets are pale green, with an orange-yellow marking on the top of the head and long antennae. (espacepourlavie.ca)
  • The head is rounded on top and there is a large space between the antennae at their base. (espacepourlavie.ca)
  • The process has been gaining prominence in the study of Cambrian arthropod macrofossils during the past five years, as micro-CT machines have become more powerful, affordable, and common in research labs around the world. (harvard.edu)
  • They have relatively large antennas and 7 pairs of legs. (ewsgroup.de)
  • They have eight legs, two pairs of antennae, and three pairs of eyes . (householdguide.com)
