Ophthalmic research has developed into a multidisciplinary enterprise that requires the collaboration of basic and clinical scientists to understand and treat diseases that affect virtually every step in vision: from the entrance of light into the eye, through transduction in the retina, to higher processing in the visual cortex. It is a challenge to create and support a critical mass of divers...

Burch und Kohn haben in [4] bzw. [7] folgendes bewiesen: R sei ein kommutativer noetherscher Ring und n eine natiirliche Zahl, die homologische Dimension eines torsionslosen R-Moduls ist; dann existiert ein von hiichstens drei Elementen erzeugtes Ideal in R, dessen homologische Dimension gleich n ist. Buchsbaum und Eisenbud [3, p. 135, Conjecture, vgl. such Theorem 7.21 vermuten sogar, ‘jede” e...

The emetic responses induced by staphylococcal enterotoxin A (SEA), SEB, SEC2, SED, SEE, SEG, SEH, and SEI in the house musk shrew (Suncus murinus) were investigated. SEA, SEE, and SEI showed higher emetic activity in the house musk shrew than the other SEs. SEB, SEC2, SED, SEG, and SEH also induced emetic responses in this animal model but relatively high doses were required. The house musk sh...

OBJECTIVE This study explored the intervention effect of the "Nutrition on the Go" strategy on the prevalence of overweight and obesity (OW+O), according to the role played by different patterns. MATERIALS AND METHODS Pattern Groups (PG) were determined based on schools' food availability and other variables at individual level: nutrition knowledge, physical activity, socioeconomic level and ...

A Li-ion cell typically consists of a carbon-based negative electrode (NE); a porous polymer membrane separator (polypropylene and/or polyethylene); and a lithiated transition metal oxide (LiMxOy, M=Co, Ni, and/or Mn) positive electrode (PE). Electrodes are made by casting slurries of PE or NE-materials, PVDF-binder and carbon-black onto metal current collectors. Mixtures of Li-salts and organi...

In 1972 Halstead first reported his investigation into natural laws of algorithm analogous toFerrari86laws of natural or physical sciences. The basic idea Ferrari, D. “Considerations on the Insularity of Per-is to separate the physical structure of algorithms formance Evaluation.” IEEE Trans. Software Eng.from the logical structure of algorithms. His theory SE-12, 6 (June 1986),...

Ageing prediction is often complicated due to the interdependency of ageing mechanisms. Research has highlighted that storage ageing is not linear with time. Capacity loss due to storing the battery at constant temperature can shed more light on parametrising the properties of the Solid Electrolyte Interphase (SEI); the identification of which, using an electrochemical model, is systematically ...
