We report a family of propeller-shaped polynuclear metal complexes whose overall chirality is dictated by a single stereogenic centre within their component Calcium Carbonate amino alcohol-ligand.These topologically intriguing complexes are readily prepared in enantiomerically pure form and are shown here to catalyse the conjugate addition of barbi
The research included 520 dairy cows on 64 mini-farms in mountainous Serbian areas, with the goal to acquire an insight on acropodium diseases frequency in dairy cows, as well as distribution of hoof alterations.In 56.25% of farms, animals were kept tied in the stable, while 43.75% were grazing regularly or occasionally.Only 10.94% of farms were fr
This research investigates the effect of blade density and elevation above sea level on the startup time (Ts) and power coefficient (Cp) of a 1-kW two-bladed wind turbine.The study uses three Iranian hardwoods as the blade material and four counties of Iran with low wind speeds and different elevations as the case studies.The BW-3 airfoil is consid
Novel MRI contrast methods, such GREEN TEA EXTRACT as Chemical Exchange Saturation Transfer (CEST), rely on previously developed theory and approaches, often introduced first in solidstate NMR.Understanding or at least connecting the basic principles and original works to the modern-day contrast methods in MRI is instructive.The work brings togethe
This paper presents an analysis of defined nominal expressions as a resource for constructing the image of the Supreme Court Minister, Joaquim Barbosa, in a cover story published in Veja magazine on October 10th of 2012.The theoretical basis is Text Linguistics (KOCH; TRAVAGLIA, 1991; KOCH, 1997, 2002, 2009; GALEMBECK, 2005; MARCUSCHI, 2008; BENTES
