In today's scientific environment scientists can no longer work in isolated laboratories. The problems being studied require experts from several fields to combine their talents. The instruments used to gather scientific data are expensive and difficult to build so there are only a few in the world. The Internet connectivity and the powerful desktop workstations available today provide the pote...

Two hundred twenty-five lactation and litter performance records from 82 does representing four genetic groups and two diets were analyzed to quantify breed, heterosis, reciprocal F1 cross and diet effects for milk production and associative traits. Doe genetic groups were New Zealand White (NN) and Californian (CC) straightbred and Californian x New Zealand White (CN) and New Zealand White x C...

∗∗ Local and global properties of the moduli space of Calabi–Yau type compactifications determine the low energy parameters of the string effective action. We show that the moduli space geometry is entirely encoded in the Picard–Fuchs equations for the periods of the Calabi– Yau H–cohomology. ∗ Supported in part by DOE grants DE-AC0381-ER500050, DOE-AT03-88ER40384, task E and by MURST.

در این مطالعه فرایند گرمایش خطی با لیزر برای سه سرعت مختلف به صورت تحلیل عددی و آزمایش تجربی بررسی شده است. تحلیل عددی از نوع تحلیل کوپله (حرارتی- مکانیکی) و با استفاده از نرم افزار ansys صورت گرفته است. همچنین برای آزمایشهای تجربی ورق های فلزی به کمک لیزر توان پائین، شکل دهی شده اند. قبل از انجام آزمایشها، ابتدا روش طراحی آزمایشهای عاملی کامل (full factorial design) انتخاب و با توجه به این طرا...

Climate change, limited fossil resources and steady population growth drive industrial development of sustainable biomass based processes for production of fuels, platform and specialty chemicals. In this context phototrophic microalgae cultivation processes are poised to play a central role for development of next generation bioprocesses due to high cellular growth rates and excellent yields o...

The US DOE Joint Genome Institute (JGI) sequences microbial and metagenomic projects through three main programs: DOE Microbial Genome Program (MGP), JGI Community Sequencing Program (CSP) and DOE Genomes to Life Program (GTL). The principle goal of the MGP is to fund sequencing projects related to DOE interests, the principle goal of the CSP is to fund sequencing projects from a broad range of...

We incorporate all existing solar neutrino flux measurements and take solar model flux uncertainties into account in deriving global fits to parameter space for the MSW and vacuum solutions of the solar neutrino problem. Also Department of Astronomy. Research supported in part by the DOE, the NSF and the TNRLC. Bitnet: KRAUSS@YALEHEP Supported in part by the DOE.

The paper considers a sequential Design Of Experiments (DOE) scheme. Our objective is to maximize both information and economic measures over a feasible set of experiments. Optimal DOE strategies are developed by introducing information criteria based on measures adopted from information theory. The evolution of acquired information along various stages of experimentation is analyzed for linear...

The Clostridia are a diverse group of gram-positive, rod-shaped anaerobes that include several toxin-producing pathogens (notably C. difSiciZe, C. botulinum, C. tetuni, and C. perfringens) and a large number of terrestrial species that produce acetone, butanol, ethanol, isopropanol, and organic acids through fermentation of a variety of carbon ~ o u r c e s ~ ~ . Isolates of C. ucetobutylicum w...

Kaluza-Klein sphere reductions of supergravities that admit AdS×Sphere vacuum solutions are believed to be consistent. The examples include the S4 and S7 reductions of eleven-dimensional supergravity, and the S5 reduction of ten-dimensional type IIB supergravity. In this paper we provide evidence that sphere reductions of supergravities that admit instead Domain-wall×Sphere vacuum solutions are...
