UV vision is prevalent, but we know little about its utility in common general tasks, as in resolving habitat structure. Here we visualize vegetated habitats using a multispectral camera with channels mimicking bird photoreceptor sensitivities across the UV-visible spectrum. We find that the contrast between upper and lower leaf surfaces is higher in a UV channel than in any visible channel, and t

The field of radial turbines is wide and radial turbines of today find applications in areas as diverse as small gas turbines; turbochargers for cars, buses, and trucks, railway locomotives, and diesel power generators; cryogenic and process expanders; rocket engine turbopumps; and specialty steam turbines.

The binding between colipase and two triacylglycerol substrates, tributyrin and Intralipid, in the presence of bile salts have been determined quantitatively by a method based on equilibrium partition in an aqueous two-phase system. In the model proposed the triacylglycerol, in the form of spherical droplets covered with bile salt, is assumed to have a certain number of independent binding sites a

The effect of different bile salts on amylase release from isolated rat pancreatic acini has been studied. The bile salt-stimulated discharge of amylase could be divided into three situations, depending on the concentration of bile salt. At low concentrations, between 1 and 100 X 10(-6)M, there was a slight increase in amylase secretion, 5-7% of total, which varied with the type of bile salt but w

Objective: To determine the role of inflammatory biomarkers at 2 years post–anterior cruciate ligament (ACL) injury to predict radiographic knee osteoarthritis (OA) and magnetic resonance imaging (MRI)–defined knee OA at 5 years postinjury, with a secondary aim of estimating the concordance of inflammatory biomarkers assessed by MRI and synovial fluid (SF) analysis. Methods: We studied 113 patient

OBJECTIVE: To investigate the impact of exercise therapy on molecular biomarkers related to cartilage and inflammation in people at risk of, or with established, knee osteoarthritis by conducting a systematic review of randomized controlled trials (RCTs).METHODS: Literature search up to September 2017 in five major databases with no restriction on publication year or language. Data were extracted

The effect of human pancreatic polypeptide (HPP) on rat pancreatic acini has been studied. It was found that HPP stimulated amylase and lipase release from the acini. The secretory response of acini to HPP was dose-dependent in a sigmoidal fashion. Between 10(-9) M and 10(-8) M concentration of HPP there was a slow increase of enzyme release to about 40-60% over basal release. At concentrations of

Colipase is excreted as a procolipase, colipase101. It is activated by low concentrations of trypsin, hydrolyzing the N-terminal pentapeptide. With higher concentrations of trypsin or in the presence of Ca2+ a smaller form of colipase containing 85 amino acids, appears. It has glycine as the N-terminal and arginine as the C-terminal amino acid residue and has lost 11 amino acids in the C-terminal

Colipase exists in pancreatic juice in a pro-form which is activated by limited trypsin hydrolysis. During this activation, the N-terminal pentapeptide 1Val-Pro-Asp-Pro-5Arg is cleaved. The new N-terminal sequence formed, 6Gly-Ile-Ile-Ile-10Asn, contains three isoleucine residues. The importance of these for stimulating lipase activity has been investigated by successive Edman degradation of epsil

This study examines a recent reform in the Swedish teaching profession—the so-called first teacher reform, aimed at increasing teacher professionalism and the status of teachers. The reform created a situation by which a new role had to be created and inhabited by first teachers, appointed on what were considered arbitrary criteria. There were few existing norms, rules, and routines to draw upon f

Vilken slags profession är lärarkåren? Är lärarkåren ens en profession? Vad innebär autonomi och hur påverkas en yrkesgrupp av att det uppstår hierarkier inom den? Den här boken, om förstelärarreformens införande i svensk skola, för en nyanserad diskussion av dessa frågor som ytterst handlar om förutsättningarna för lärares yrkesutövning.Författarna visar att förestelärarreformen har stärkt lärarn
