Observations on Parental Care in the Family Aradidae (Heteroptera).

New observations of maternal care by Neuroctenus simplex and N. elongatus are reported

Voltinism and Laboratory Rearing of \u3ci\u3eMicrovelia Hinei\u3c/i\u3e (Heteroptera: Gerromorpha: Veliidae)

Voltinism in Microvelia hinei was studied in southern Illinois during 1989 and 1990. This species apparently overwintered as adults, which became active in late April; adults were last collected in late September. First instars were found from mid-May to late June, second instars from early-May to late October, third instars from mid-May to mid-July, fourth instars from mid-May to mid-August, and fifth instars from mid-May to mid-August. The sequences of peaks of nymphal instars and adults indicate that this species is at least bivoltine in southern Illinois. This species was reared from egg to adult at 26.7 ± 0.6°C and under a 14L:10D photoperiod. The incubation period averaged 6.41 days; and the five nymphal stadia, 4.28, 2.76, 2.52, 3.00, and 4.08 days, respectively. Total developmental time averaged 25.00 days

State Records and Confirmations of Arkansas Flat Bugs (Heteroptera: Aradidae)

Eight aradid species are reported for the first time from Arkansas including Aneurus pygmaeus, Aradus cincticornis, Aradus crenatus, Quilnus niger, Mezira granulata, Mezira lobata, Mezira sayi, and Neuroctenus simplex. The presence of Aradus acufus, Aradus falleni, and Aradus robustus in Arkansas is confirmed

Distinguishing Nymphal Instars of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Heteroptera: Mesoveliidae)

The five nymphal instars of Mesouelia mulsanti can be separated by the number of rows of setae on the second abdominal tergum. Fifth instars can be separated from younger instars and from each other by the degree of development of the external genitalia

Comparison of Two Population Sampling Methods Used in Field Life History Studies of \u3ci\u3eMesovelia Mulsanti\u3c/i\u3e (Heteroptera: Gerromorpha: Mesoveliidae) in Southern Illinois

A field life history study of Mesovelia mulsanti was conducted in south­ern Illinois, the results of which are compared with those from an earlier study also conducted in southern Illinois. The two studies differed in the collecting techniques used (quadrat sampler versus aquatic net). Results of the present study give a clearer picture of the life history of this insect be­ cause the quadrat sampler collected representative samples of nymphs and adults more effectively than the aquatic net and, thus, the quadrat samples more accurately represented the actual chronology of the annual generations

Throughput Performance Evaluation and Analysis of Unmodified Bluetooth Devices

The Air Force relies on the application of new technologies to support and execute its mission. As new technologies develop, the integration of that technology is studied to determine the costs and benefits it may provide to the war fighter. One such emergent technology is the Bluetooth wireless protocol, used to connect a small number of devices over a short distance. The short distance is a feature that makes using the protocol desirable. However short, there is still a vulnerability to interception. This research identifies ranges at which several commercially available Bluetooth devices are usable. Various combinations of both distance and orientation are varied to determine a 360 degree map of the Bluetooth antenna. The map identifies distances at which certain throughput thresholds are available. This research shows that baseline 1 mW Bluetooth antennas are capable of throughput levels of 100 kbps at over 40 meters, which is four times the minimum distance specified in the protocol standard. The 3Com PC card was the best performing PC card, capable of throughputs at or near 100 kbps out to 40 meters. The other PC Cards tested had similar performance. The Hawking USB dongle was the best USB antenna tested, achieving throughputs of over 200 kbps in three of the four orientation, and over 150 kbps at the fourth. The 3Com dongle was a close second, the Belkin dongle a distant third, while the DLink antenna was not able to achieve 100 kbps at any distance tested

Academic Programs in Disability Studies

This article contains a listing of Disability Studies programs in North American Academic Institutions. The title "Disability Studies" has become popular and is sometimes used to refer to programs in clinical or instructional fields. The programs in this listing meet the following criteria: (1) the sponsoring university offers a four-year undergraduate degree or Master's or doctoral degrees; (2) the programs offer a formal academic program, including a degree, concentration, specialization, minor, major, or certificate in Disability Studies; (3) the programs include disability course work in non-clinical and non-instructional fields (e.g., the Humanities, Social Sciences, Literature, Law, Policy Studies, or the Visual or Performing Arts); and (4) information describing the programs can be found in written form or on a university web site. This listing does not include research or training centers that do not offer formal academic programs
