We consider a distribution system consisting of a central warehouse and a group of retailers facing independent stochastic demand. The retailers replenish from the warehouse, and the warehouse from an outside supplier with ample supply. Time is continuous. Most previous studies on inventory control policies for this system have considered stock-based batch-ordering policies. We develop a time-base

Although much attention in recent years has been devoted to methane (CH4) emissions from northern wetlands, measurement based data sets providing full annual budgets are still limited in number. This study was designed to help fill the gap of year-round measurements of CH4 emissions from subarctic mires. We report continuous eddy correlation CH4 flux measurements made during 2006 and 2007 over the

In cross-national studies, mean levels of self-reported phenomena are often not congruent with more objective criteria. One prominent explanation for such findings is that people make self-report judgements in relation to culture-specific standards (often called the reference group effect), thereby undermining the cross-cultural comparability of the judgements. We employed a simple method called a

Elevated intracranial pressure (ICP) is an important cause of secondary brain injury, and a measurement of ICP is often of crucial value in neurosurgical and neurological patients. The gold standard for ICP monitoring is through an intraventricular catheter, but this invasive technique is associated with certain risks. Intraparenchymal ICP monitoring methods are considered to be a safer alternativ

To evaluate the prediction of large-for-gestational age (LGA) term neonates using the routine third-trimester ultrasound examination and to investigate whether the prediction could be further improved by adding information on maternal characteristics.

We consider a dipolar Bose-Einstein condensate confined in an annular potential, with all the dipoles being aligned along some arbitrary direction. In addition to the dipole-dipole interaction, we also assume a zero-range hard-core potential. We investigate the stability of the system against collapse, as well as the stability of persistent currents as a function of the orientation of the dipoles

The brown tail moth (BTM) Euproctis chrysorrhoea (Linnaeus 1758) (Lepidoptera: Erebidae) is a forest and ornamental pest in Europe and the United States. Its extreme polyphagy, and documented phenological shift associated with host use suggest the presence of distinct host-races. To test this hypothesis, we sampled BTM infesting different host species in several locations along its distribution, a

Gene amplification is relatively common in tumors. In certain subtypes of sarcoma, it often occurs in the form of ring and/or giant rod-shaped marker (RGM) chromosomes whose mitotic stability is frequently rescued by ectopic novel centromeres (neocentromeres). Little is known about the origin and structure of these RGM chromosomes, including how they arise, their internal organization, and which s

TnBgl1A from the thermophile Thermotoga neapolitana is a dimeric beta-glucosidase that belongs to glycoside hydrolase family 1 (GH1), with hydrolytic activity through the retaining mechanism, and a broad substrate specificity acting on beta-1,4-, beta-1,3- and beta-1,6-linkages over a range of glyco-oligosaccharides. Three variants of the enzyme (TnBgl1A_E349G, TnBgl1A_E349A and TnBgl1A_E349S), mu

The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover tr

Objective: This study evaluated changes in self-efficacy in non-physically active adolescent girls (13-19 years old) who participated in a six-month, empowerment-based exercise intervention programme (EIP). Design: The study used a pre- and post-test randomized group design and included one pre-and one posttest (at six months) and non-physically active adolescent girls (N = 110) were assigned to a

This paper deals with policy measures in the regional innovation system of Scania, Southern Sweden. Focus is on the innovation policy requirements of actors representing industries that draw on different knowledge bases. Previous studies have identified profound industry-specific differences concerning the organisation of knowledge sourcing between firms and other actors. In correspondence with th

Currently available research suggests that negative pressure wound therapy (NPWT) creates a moist wound healing environment, drains exudate, reduces tissue edema, contracts the wound edges, mechanically stimulates the wound bed, and influences blood perfusion at the wound edge, which may lead to angiogenesis and the formation of granulation tissue. Although no clear evidence is available that NPWT

We have analyzed the geochemistry and mineralogy of the five characteristic beds that constitute the Dababiya Quarry Member (DQM) recovered from the Dababiya Quarry Core located near the Global Stratotype Section and Point (GSSP) for the base of the Eocene. Well developed in Upper Egypt, these beds are known to record the isotopic and biotic signatures of the Paleocene/Eocene thermal maximum (PETM

The phonological trace of perceived words starts fading away in short-term memory after a few seconds. Spoken utterances are usually 2–3 s long, possibly to allow the listener to parse the words into coherent prosodic phrases while they still have a clear representation. Results from this brain potential study suggest that even during silent reading, words are organized into 2–3 s long ‘implicit’

Previous studies on healthy subjects have shown that the intake of 6 g Cinnamomum cassia reduces postprandial glucose and that the intake of 3 g C. cassia reduces insulin response, without affecting postprandial glucose concentrations. Coumarin, which may damage the liver, is present in C. cassia, but not in Cinnamomum zeylanicum. The aim of the present study was to study the effect of C. zeylanic

A novel pathlength enhancement approach has been applied in multimode diode laser correlation spectroscopy measurements of gas concentrations. Reference and sample gas cells made of porous polystyrene foam and alumina ceramic, respectively, were employed in proof-of-principle measurements of molecular oxygen. Equivalent pathlengths of 164 and 52 cm were obtained for the reference and sample cells

Attempts to engage critically with citizenship, both within critical human rights theory and within cosmopolitan and multicultural citizenship theory, often underline how the status of the citizen has ceased to be perceived as a privilege and is instead viewed in terms of universal access to political rights and political participation. The political man is thus constituted by his citizenship and
