The American species of the annulatipes group of the subgenus Lepidohelea, genus Forcipomyia (Diptera: Ceratopogonidae)

The annulatipes group of the genus Forcipomyia Meigen, subgenus Lepidohelea Kieffer, is represented in the Western Hemisphere by 12 species. Keys are presented for their identification, and to distinguish them from other groups of the subgenus Lepidohelea. The three previously known species, annulatipes Macfie, brasiliensis Macfie, and kuanoskeles Macfie, from southern Brazil, as well as the following nine new species, are described and illustrated: bahiensis, basifemoralis, bifida, convexipenis, euthystyla, gravesi, herediae, hobbsi, and weemsi

Vehicle test report: Jet Industries Electra Van 600

The Electra Van 600, an electric vehicle, was tested. Tests were performed to characterize parameters of the Electra Van 600 and to provide baseline data to be used for comparison of improved batteries and to which will be incorporated into the vehicle. The vehicle tests concentrated on the electrical drive subsystem, the batteries, controller, and motor; coastdowns to characterize the road load and range evaluation for cyclic and constant speed conditions; and qualitative performance was evaluated. It is found that the Electra Van 600 range performance is approximately equal to the majority of the vehicles tested previously

The subgenus \u3ci\u3eAtrichopogon (Lophomyidium\u3c/i\u3e) with a revision of the Nearctic species (Diptera: Ceratopogonidae)

Atrichopogon Kiefer, subgenus Rostropogon Remm, is a junior synonym of the subgenus Lophomyidium Cordero (NEW STATUS, NEW SYNONYMY). Monohela ocumare Ortiz from Venezuela is transferred to Atricopogon (Lophomyidium) (NEW COMBINATION). The Holarctic species Atrichopogon polydactylus Nielsen is a junior synonym of A. fusculus (Coquillet), a widespread and common species previously reported from only the Western Hemisphere. Four Nearctic species are described as NEW SPECIES: A. jamnbacki from salt and brackish marshes along the Atlantic coast from Nova Scotia to North Carolina; the following freshwater species A. deyrupi from southern Florida; A archboldi, from southern Florida, Texas and California, and southward well into the Neotropical Region and A. borkenti, from western Canada. The larvae of A. (Lophomyidium) are found on wet wood, soil, and stones in marshy habitats. Adults of A. fusculus have been observed feeding on insect carrion in spider webs

Vehicle test report: Electric Vehicle Associates electric conversion of an AMC Pacer

Tests were performed to characterize certain parameters of the EVA Pacer and to provide baseline data that can be used for the comparison of improved batteries that may be incorporated into the vehicle at a later time. The vehicle tests were concentrated on the electrical drive subsystem; i.e., the batteries, controller and motor. The tests included coastdowns to characterize the road load, and range evaluations for both cyclic and constant speed conditions. A qualitative evaluation of the vehicle's performance was made by comparing its constant speed range performance with other electric and hybrid vehicles. The Pacer performance was approximately equal to the majority of those vehicles assessed in 1977

Vehicle test report: Electric Vehicle Associates electric conversion of an AMC Pacer

The change of pace, an electric vehicle was tested. These tests were performed to characterize certain parameters of the electric vehicle pacer and to provide baseline data that can be used for the comparison of improved batteries that may be incorporated into the vehicle at a later time. The vehicle tests were concentrated on the electrical drive subsystem, the batteries, controller and motor. Coastdowns to characterize the road load, and range evaluations for both cyclic and constant speed conditions were performed. The vehicle's performance was evaluated by comparing its constant speed range performance with described vehicles. It is found that the pacer performance is approximately equal to the majority of the vehicles tested in the 1977 assessment

A novel and precise time domain description of MOSFET low frequency noise due to random telegraph signals

Nowadays, random telegraph signals play an important role in integrated circuit performance variability, leading for instance to failures in memory circuits. This problem is related to the successive captures and emissions of electrons at the many traps stochastically distributed at the silicon-oxide (Si-SiO2) interface of MOS transistors. In this paper we propose a novel analytical and numerical approach to statistically describe the fluctuations of current due to random telegraph signal in time domain. Our results include two distinct situations: when the density of interface trap density is uniform in energy, and when it is an u-shape curve as prescribed in literature, here described as simple quadratic function. We establish formulas for relative error as function of the parameters related to capture and emission probabilities. For a complete analysis experimental u-shape curves are used and compared with the theoretical aproach

The Neotropical Predaceous Midges of the genus \u3ci\u3eBezzia\u3c/i\u3e (Diptera: Ceratopogonidae) Part IV. The \u3ci\u3edentifemur\u3c/i\u3e and \u3ci\u3evenustula\u3c/i\u3e Groups

The dentifemur and venustula groups of the subgenus Homobezzia Macfie, genus Bezzia Kieffer, are represented in the Neotropical Region by 12 species. A key is presented for their identification, and to distinguish them from other groups of the subgenus Homobezzia. The two previously known species, B. venustula (Williston) and B. snowi Lane, are described and illustrated, as well as the following ten new species: aitkeni, bromeliae, cayoensis, dentifemur, filiductus, fusca, mexicana, nigritibialis, pseudovenustula, and raposoensis. Bezzia concoloripes Made is regarded as a junior synonym of B. venustula (Williston)

The "Forcipomyia ingrami" Complex in Hawaii (Diptera: Ceratopogonidae)

Biting midges of the genus Forcipomyia are some of the most important pollinators of cacao and other tropical crop plants. A study of the species known as F. ingrami revealed that it has been misidentified, and that the African species formerly known as ingrami, now psilonota, does not occur in Hawaii. Instead there are at least four other species: palikuensis Hardy, a large, shining blackish species from Hawaii and East Maui; kaneohe n. sp., a small shining species from Oahu; pholeter n. sp., a small pale species living in lava tube caves on Hawaii; and hardyi n. sp., a dull brownish species which is extremely common on all the islands; all probably endemic to the Hawaiian Islands. The immature stages of these midges, which breed in wet, decaying vegetation, leaf axils, and aquatic vegetation, have excellent characters diagnostic for species. Characters are illustrated and discussed showing how these species may be distinguished from their closely related congeners from the Pacific, Asia, and Africa. Forcipomyia clara Chan and LeRoux from Singapore is a junior synonym of F. sauteri Kieffer (N. SYNONYMY)
