Endoxylanases are a group of enzymes that hydrolyze the beta-1, 4-linked xylose backbone of xylans. They are predominantly found in two discrete sequence families known as glycoside hydrolase families 10 and 11. The Streptomyces lividans xylanase Xyl10A is a family 10 enzyme, the native structure of which has previously been determined by x-ray crystallography at a 2.6 A resolution (Derewenda, ...

We show that an ostensibly disparate set of stylized facts regarding firm pricing behavior can arise in a Ricardian model with Bertrand competition. Generalizing the Bernard, Eaton, Jenson, and Kortum (2003) model allows firms’ markups over marginal cost to fall under trade liberalization, but increase with FDI, matching empirical studies in international trade. We are able to mesh this dichoto...

[1] We present a robust optimization method for estimating aquifer storage parameters (specific yield or storativity) using the Gravity Recovery and Climate Experiment (GRACE) data, in situ well level observations, and other ancillary information. Uncertainty inherent in the remotely sensed and in situ time series can adversely affect the parameter estimation process and, in the worse case, mak...

Acetate grown cells of Azotobacter, like sucrose grown cells (Stone and Wilson, 1952), are unadapted to the oxidation of succinic acid although possessing an enzyme system capable of oxidizing succinate. Hence the adaptation of these cells to succinic acid may be termed a functional change in the physiology of the organism. In contrast, glucose grown cells of Saccharomyces cerevisae are unadapt...

Using plant data that distinguish between occupations, tasks, and workforce skills, this paper investigates the relationship between offshoring and the onshore workforce composition at German multinational enterprises (MNEs) in manufacturing and services. There is no statistically significant association between offshoring and the share of whiteand blue-collar jobs in the onshore wage bill. The...

A recent test for the existence of suture zones in North America, based on hybrid zones studied since 1970, found support for only two of the 13 suture zones identified by Remington in 1968 (Swenson and Howard 2004). One limitation of that recent study was the relatively small number of hybrid zones available for mapping. In this study, we search for evidence of clustering of contact zones betw...

than any of the other grass mixtures when collected in the cured stage. Since aphosphorosis did not occur during the winter blood sampling period, phosphorus accumulated during the growing period on winter and alpine ranges may influence blood phosphorus during the winter when forage phosphorus is in short supply. At this time it is not known to what degree a free-ranging animal can accumulate ...

A study of 13 grapevine cultivars was carried out in a vineyard located near Krakow (Poland) in order to identify the most suitable grapevine cultivars for cool climate regions. The vines’ vigour, yield and the yield efficiency index were studied in the years 2010-2013. The grapes were analysed to determine soluble solids content (SSC), titratable acidity, total polyphenol content (TPC) as well...
