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

Hantering av problem och förebyggande av konflikter under handledning av examensarbeten

Syftet med denna studie har varit att söka ett systematiskt sätt att hantera problemsituationer under examensarbetshandledning. Ett teoretiskt ramverk har framställts med hjälp av litteratur om arbetspsykologi respektive handledning av doktorander. För att testa relevans och giltighet av ramverket genomfördes en intervju-undersökning om hantering av problematiska handlednings-situationer bland lär

Postischemic housing in an enriched environment influences hippocampal progenitor cell differentiation after focal cortical ischemia

We have tested the hypothesis that environmental factors can influence postischemic progenitor cell survival and differentiation in the dentate gyrus. The proliferation marker bromodeoxyuridine (BrdU) was administered during 7 days starting 24 h after ligation of the right middle cerebral artery. Postoperatively the rats were housed in standard cages or transferred to enriched environment 24 h or

Coupling a Proton and a Neutron to the Semidoubly Magic Nucleus Ni-68: A Study of Cu-70 via the Beta Decay of Ni-70 and Cu-70

The 70Ni nucleus has been produced at the LISOL facility and its beta decay to 70Cu has been observed. In parallel, the 70Cu nucleus has been produced at the ISOLDE facility. A new third beta-decaying isomeric state in 70Cu has been identified, partly with the aid of the in-source laser spectroscopy method. Its measured half-life is T1/2=33(2) s. In addition, two isomeric transitions in 70Cu have

Force Estimation and Control in Robot Manipulators

In this paper we present some results on model based force estimationand how these estimates can be integrated in a common robot force controlscheme. A generalization of the force estimation method proposed inHacksel and Salcudean (1994) is done and a force observerable to follow ramp environmental forces is introduced. Anextension of this method for robotic manipulators is also experimentallyveri
