Annotated Checklist of the Pentatomidae (Heteroptera) of Connecticut

We provide town data for the Pentatomidae in Connecticut. Although this state has been much collected, most sampling has been limited to only a few lo- cations. Species newly recorded for Connecticut are: Halyomorpha halys (Stål), Hymenarcys nervosa (Say), Banasa euchlora Stål, B. sordida (Uhler), and Perillus bioculatus (Fabricius). Podisus neglectus (Westwood) may occur in the state. Other species found in neighboring states may eventually be found in Connecticut: Picromerus bidens (Linnaeus), Rhacognathus americanus Stål, Mcphersonarcys aequalis (Say), Thyanta custator custator (Fabricius), T. custator acerra McAtee, and Amaurochrous brevitylus (Barber and Sailer). We briefly analyze these data, recognizing some faunal elements. More collecting needs to be conducted in the state, so that distribution patterns outlined here can be more broadly understood, and so that species of potential conservation concern can be identified

PRIVATE INVESTMENT IN AGRICULTURAL RESEARCH AND INTERNATIONAL TECHNOLOGY TRANSFER IN ASIA

This study addresses the questions of future sources of technology for increasing food and agricultural production by considering the situation in Asia. This region of the world is particularly appropriate for studying these questions because of the dynamic changes in population and incomes. How much private research is there and what is it producing? Will the private sector compensate for declining public agricultural research investments in Asia? What can governments do to stimulate private research and protect farmers from harmful or defective technology? Agribusiness firm's R&D investments were evaluated in selected developing countries during 1996 and 1998 and compared with data from a similar study conducted in the mid-1980s. The largest amount of private research was in India where investment was about $55 million per year in the mid-1990s, followed by Thailand, Malaysia, and China. China's private R&D spending represents less than one one-hundredth of 1 percent of agricultural gross domestic product. In contrast, in Thailand and Malaysia, firms spent about 0.1 percent. From the mid-1980s to the mid-1990s, private sector R&D grew in real terms in the countries in our sample. However, at this rate, private research will not fill the gap needed to support rapid growth in demand for agricultural products. Foreign firms made an important contribution to private research in all of these countries. The most important policy that helped induce this growth was liberalization of industrial policy that allowed private and foreign firms to operate and expand in agricultural input industries. A second important policy was investments in public research. Patents and tax incentives seem to have had little effect so far, but could be important in the future.Agricultural research and development (R&D), private sector R&D, technology transfer, Asian R&D, Research and Development/Tech Change/Emerging Technologies,

The Beech Line in Northwestern Indiana

An Indiana beech is without doubt one of the most sensitive indicators of decline in mesphytism in habitat. In the rugged areas of the state it marks the borders between moist northfacing slopes and more xeric south-facing slopes. This was shown by Potzger, Potzger and Friesner for the southern as well as for the eastern part of Indiana. Beech also records the effects which the increase of steepness of slope has on the usual more mesic conditions of north-facing slopes. This characteristic of the species suggested a study of the forests along the eastern periphery of our Indiana prairie area to see if the transition between mesophytic forest and prairie functioned as a progressive change or represented a sudden break between two vegetation types. The senior author is engaged in a study of the original vegetation of the state, using as basis the witness trees noted and recorded by the men who made the original U. S. land survey. The study of distribution of beech along the border of the prairie peninsula is one of several papers dealing with phases of the state-wide survey which seem to warrant more detailed consideration

Estimating Hourly Solar Radiation for One-Axis Tracking Focusing Collectors

Performance simulations of focusing parabolic collectors are hampered by a limited amount of useful insolation data. Hourly values of total radiation on a horizontal surface are the most common data available from the National Oceanographic & Atmospheric Administration. This paper develops a method to convert this total horizontal radiation to direct radiation on the surface of the tracking collector

All-Metallic Phase Change Thermal Management Systems for Transient Spacecraft Loads

In this work, we explore the thermal properties of gallium as an effective phase change material for thermal management applications. Thermal storage and dissipation of gallium manufactured heat sinks were compared to conventional phase change heat sinks. The comparison revealed a 50-fold (80 K versus 1.5 K) potential reduction in temperature during the phase change process due to the high density, thermal conductivity, and latent heat of fusion. The gallium creates shallow thermal gradients when transiently heated, producing a nearly isothermal process. Computational estimates using lumped sum parameters were able to provide simple modeling to predict the results. Gallium based phase change devices offer a combination of low volume, small temperature drops across the device, simplicity of manufacture and design, and high energy storage applications

Leading-Log Effects in the Resonance Electroweak Form Factors

We study log corrections to inelastic scattering at high Bjorken x for Q^2 from 1 to 21 GeV^2. At issue is the presence of log corrections, which can be absent if high x scattering has damped gluon radiation. We find logarithmic correction of the scaling curve extrapolated to low Q^2 improves the duality between it and the resonance plus background data in the Delta region, indicating log corrections exist in the data. However, at W > 2 GeV and high x, the data shows a (1-x)^3 form. Log corrections in one situation but not in another can be reconciled by a W- or Q^2- dependent higher twist correction.Comment: 13 pages, report nos.
