Increased focus on values. A tool in stress prevention?

Background and purpose Can an increased focus on values in working life be a factor in stress prevention? Values are defined as the shared principles which guide behaviour in an organisation. The purpose of this study was to describe how patients with musculoskeletal pain perceive the importance of values in relation to coping with daily stress and in relation to health. Methods Patients receivi

Hållbar utveckling, strategier på program- och kursnivå

Efter HSVs utvärdering av CI- utbildningarna fick högskolorna ett tydligt uppdrag att vid uppföljningen redovisa hur hållbar utveckling kommer in i utbildningarna. I planeringsförutsättningarna för de 5-åriga civilingenjörsutbildningarna vid LTH finns kravet på examination av minst 6 hp inom området.

Does the Measurement of Intra-Industry Trade Matter?

Does the Measurement of Intra-Industry Trade Matter? - This paper discusses different methods of capturing the main aspects of the Chamberlin-Heckscher-Ohlin-Samuelson model. Of particular interest are the distinction between horizontal and vertical intra-industry trade, the adjustment of aggregation biases, and the definition of inter- and intra-industry specialization at product level. The main

Functional collaboration between HLH transcription factors in B cell development.

Popular Abstract in Swedish Alla friska människor har 46 kromosomer, 23 av dessa härstammar från modern och 23 från fadern. Kromosomer är långa kedjor av nukleinsyror som innehåller den genetiska informationen (arvsanlagen) som behövs för att ett befruktat ägg skall kunna utvecklas till en individ bestående av miljontals celler med mycket specialiserade och avancerade uppgifter. Den här utvecklingThe cells in B cell development can be divided into several subgroups or fractions, e.g. early-pro-B-, pro-B, large-pre-B-, small-pre-B-, immature and mature B cells, where the stages reflect the maturity degree of the cells. This characterization is based on the expression of intracellular markers such as the recombination activating genes 1 and 2(Rag 1 and Rag 2), the terminal deoxynucleotidyl t

Analysis of Degradation Products from Wood and Methods for Detoxification of Lignocellulose Hydrolysates

Popular Abstract in Swedish Med dagens alla transporter finns det ett mycket stort behov av tillgång till billigt och miljövänligt drivmedel. Det bränsle som används i särklass mest är bensin framställd från råolja. Ett problem med bensinen är att den inte tillverkas från förnyelsebara råvarukällor. Detta innebär att när oljan tar slut så går det inte att tillverka mer bensin. Däremot är det idag In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. Several of these compounds might act as inhibitors during the fermentation of the sugars to ethanol. Thus, in order to obtain high etha

Fast Implementation of SAR Imaging Using Sparse ML Methods

High-resolution sparse spectral estimation techniques have recently been shown to offer significant performance gains as compared to most conventional estimation approaches, although such methods typically suffer the drawback of being computationally cumbersome. In this paper, we seek to alleviate this drawback somewhat, examining computationally efficient implementations of the recent iterative s

A comparative study of pilot-based channel estimators for wireless OFDM

This report deals with pilot-based channel estimation in wireless OFDM systems. We assume that the receiver is able to use all transmitted pilots, which is the case in broadcasting and in the downlink of a multiuser system. Four estimators (of which two have been proposed in the literature) are compared, both in terms of mean-squared error and bit-error rates. In the latter case, we simulate a mul
