Deep X-ray lithography using synchrotron radiation with a characteristic wavelength of about 1 3 A is a powerful tool to generate threedimensional microstructures in thick layers of polymeric resists. Resist reliefs produced in this way are used in the framework of the so called LIGA process, as precise templates to generate microdevices from metals, plastics, ceramic materials, and glasses. A ...

A study was conducted to determine the effects of dietary glycerol on dry matter intake (DMI), milk yield and components, blood metabolites, and efficiency in the transition cow. The study was conducted from Feb. to Oct. of 2008 using 48 cows (25 primiparous and 23 multiparous). The study ran from 3wk prepartum to 8wk postpartum with a randomized block design using a 2 × 2 factorial. Treatments...

-The subcutaneous growth of 2 antigenically distinct syngeneic methylcholanthrene-induced murine fibrosarcomas, designated HI and H7, were significantly augmented by the concomitant administration of E. coli endotoxin (LPS). Amounts as little as 0*02 ,-g i.p. potentiated tumour growth. The weakly antigenic tumour, Hi, was more susceptible to provocation by LPS than the more strongly antigenic H...

An abundance of agricultural by-products have been used to feed dairy and beef cattle in Taiwan, in order to reduce the cost of livestock production. Most farmers are not concerned about the nutrient value of agricultural by-products. They need to be educated on how to utilize by-products properly. Research to improve techniques of preservation and the efficiency of utilization of agricultural ...

An approach to develop Organizational Memory Systems is presented. It is based on the re-use of computer-supported discussions held as meeting preparations. The discussions are rich in informal knowledge, which is basic for a good Organizational Memory. The presentation is illustrated with a brief introduction to OMUSISCO, a software system based on the approach. OMUSISCO uses SISCO meeting pre...

Contact dermatitis due to cosmetic products is a common dermatologic complaint that considerably affects the patient's quality of life. Diagnosis, treatment, and preventive strategies represent a substantial cost. This condition accounts for 2% to 4% of all visits to the dermatologist, and approximately 60% of cases are allergic in origin. Most cases are caused by skin hygiene and moisturizing ...

Lipid peroxidation is a process involving the oxidation of polyunsaturated fatty acids (PUFAs), which are basic components of biological membranes. Reactive electrophilic compounds are formed during lipid peroxidation, mainly alpha, beta-unsaturated aldehydes. These compounds yield a number of adducts with DNA. Among them, propeno and substituted propano adducts of deoxyguanosine with malondial...

We prove that rationally essential manifolds with suitably large fundamental groups do not admit any maps of non-zero degree from products of closed manifolds of positive dimension. Particular examples include all manifolds of non-positive sectional curvature of rank one and all irreducible locally symmetric spaces of non-compact type. For closed manifolds from certain classes, say non-positive...

Exsheathing fluid (EF) and excretory-secretory products (ES) of infective third-stage cultured larvae ofOstertagia circumcincta were analysed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDSPAGE). Five and seven predominant proteins were found in the EF and ES products, respectively. Immunoblotting by sheep pre-infection serum did not react with any of the EF and ES proteins, b...
