Literature reviews lay the foundation for almost every academic research project, and sometimes are a scholarly contribution in its own right. To increase rigor and credibility the findings have to be valid and reliable just as in any other type of research. This paper summarizes recent methodological developments in the application systematic literature reviews in supply chain management. It anal

This paper analyzes the I/Q imbalance effect of direct-conversion receiver in wide-band wireless communication system and sets up frequency-selective I/Q imbalance model for ultra-wide band system. We design a new training sequence based on extra phase rotation and propose an estimation algorithm using diversity message introduced by I/Q imbalance during the demodulation process. Theoretical analy

Background Lactobacillus reuteri converts glycerol to 3-hydroxypropionic acid (3HP) and 1,3-propanediol (1,3PDO) via 3-hydroxypropionaldehyde (3HPA) as an intermediate using enzymes encoded in its propanediol-utilization (pdu) operon. Since 3HP, 1,3PDO and 3HPA are important building blocks for the bio-based chemical industry, L. reuteri can be an attractive candidate for their production. However

FKBP12 serves a dual role as a peptidyl-prolyl cis-trans isomerase and as a modulator of several cell signaling pathways. The macrolide FK506 is a transition-state analog of the catalyzed reaction and displaces FKBP12 from its natural target proteins. We compared the conformational exchange dynamics of the backbone and methyl-bearing side chains of FKBP12 in the free and FK506-bound states using N

OBJECTIVES: This is the first nationwide study with the aim to analyze whether there is an association between country of birth in first-generation immigrants and hospitalization for type 2 diabetes (T2D), and to study whether any such association remains in second-generation immigrants. DESIGN: In this follow-up study, the Swedish Hospital Discharge Register was used to identify all hospital

By using a three dimensional computational method, gas flow and heat transfer have been investigated and analyzed for both cathode / anode ducts of proton exchange membrane fuel cells. The Brinkman- Forchheimer-extended Darcy model is employed to investigate the flow inside the porous layer of the duct. Effects of inertial coefficient, together with permeability, effective thermal conductivity, th

How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i
