With better understanding of the properties and mechanical behavior of wood fiber composites such as wood particle boards the final structure can be improved, both from a solid mechanical and cost effective perspective. Particle boards are widely used in today’s industry for consumer products and the mechanical properties for such materials and how it is effected by the mix of wood chips and glue
According to efficient market theory, all publicly available information is reflected in asset prices. In its semi-strong form, fundamental analysis cannot be used as a method to generate an abnormal return. Implying that abnormal return can only be achieved by incurring a higher level of risk. Joel Greenblatt (2006) shows that by applying simple fundamental analysis and ranking companies based on
Microsoft Dynamics AX (AX) is an Enterprise Resource Planning (ERP) system, and like ERP systems in general, it supports the lean production philosophy only to a limited extent. One way to provide a better support for lean production would be a feature for value stream mapping with AX as data source. The purpose of this study was to examine if plant level current state value stream maps could
Previous experiments demonstrated improved outcome following prolonged cerebral ischemia given controlled brain reperfusion using extracorporeal circulation. The current study further investigates this. Young adult pigs were exposed to 30 min of global normothermic cerebral ischemia, achieved through intrathoracic clamping of cerebral arteries, followed by 20 min of isolated mechanical brain reper
Objective: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is associated with life-threatening bleeding. This systematic review of postnatal management of FNAIT examined transfusion of human platelet antigen (HPA) selected or unselected platelets, and/or IVIg on platelet increments, hemorrhage and mortality. Study design: MEDLINE, EM
Biogenic volatile organic compounds (BVOC), such as isoprene and monoterpenes, play an important role in atmospheric processes. BVOC species are oxidized in the atmosphere and influence levels of ozone. The less volatile amongst the BVOC and their oxidation products are important for the formation and growth of secondary biogenic aerosol. In this way, the Earth's radiation balance is affected. Geo
Hormonal therapy (HT) is one of the most frequently prescribed drug regimens for women after the age of 50 years. HT has been developed progressively since the 1960s to provide estrogen to those women (a) who require relief of symptoms which have resulted from reduced circulating estrogen or (b) to act as an anti-resorptive agent to counteract the effect of the increased bone turnover which occurs
Background Dual-energy computed tomography (DECT) has conceptually been known since the late 1970s and commercially available as dual-source CT (DSCT) systems since 2006; however, the technique has not yet seen widespread implementation in routine protocols. Part of the cause for this is likely due to misconceptions about radiation dose and/or image quality when using DECT. Purpose To compare imag
A commercially available NaI(Tl) based spectrometer-dosimeter has been used to separate contributions of the terrestrial radionuclides (238U series, 232Th series and 40K) and 137Cs to the total ambient dose equivalent rate (ADER), Ḣ*(10) , outdoors. The device had been initially calibrated by the manufacturer to measure: 1) the total ADER; 2) activity concentrations of 226Ra, 232Th, 40K and ‘effec
β-Mannanases catalyze the conversion and modification of β-mannans and may, in addition to hydrolysis, also be capable of transglycosylation which can result in enzymatic synthesis of novel glycoconjugates. Using alcohols as glycosyl acceptors (alcoholysis), β-mannanases can potentially be used to synthesize alkyl glycosides, biodegradable surfactants, from renewable β-mannans. In this paper, we i
Isoprene is emitted from many terrestrial plants at high rates, accounting for an estimated 1/3 of annual global volatile organic compound emissions from all anthropogenic and biogenic sources combined. Through rapid photooxidation reactions in the atmosphere, isoprene is converted to a variety of oxidized hydrocarbons, providing higher order reactants for the production of organic nitrates and tr
We celebrate Certec’s 20th birthday . . . . . . by giving you a book of 20 important ideas filled with pictures and text. Each idea is expressed in a succinct heading that sums up what we have learned over the years. The ideas also act as a complement to all the reports, website cover pages, brochures, lectures and annual reports. There are 30,000 documents at www.certec.lth.se that provide the
The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
I mål om intrång i förfarandepatent finns särskilda svårigheter med bevisningen. Uppsatsens syfte är därför att utreda bevisproblematiken i mål om förfarandepatentsintrång. Utöver detta ska uppsatsen besvara frågeställningar kring huruvida ett processrättsligt medel kan lösa problemet och även hur man vinner framgång i mål utan att avslöja affärshemligheter. I mål där materialet är ofullständigtIn the case of infringement of method patent there is special difficulty regarding the evidence. The purpose of this essay is therefore to investigate the problem of evidence in cases of infringement of method patent. In addition, the essay is going to answer questions about whether a procedural legal remedy can solve the problem and also if it is possible to achieve success in such a case without
To enhance their applicability in a broader range of pervaporation feed streams, poly[1-(trimethylsilyl)-1-propyne] (PTMSP) membranes have been successfully crosslinked, using a 3,3'-diazido-diphenylsulfone crosslinker. Both photochemical and thermal processes were used to activate the bis(azide) and thus initiate the crosslink reaction. The presented photochemical crosslink process, has an insuff
Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-
New and innovative production equipment can be developed by introducing lightweight materials in modern day automotive industry production lines. The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternati
The global surgery workforce is in crisis in many low- and middle-income countries (LMICs). The shortage of surgery, obstetrics, and anesthesia providers is an important cause of the unmet need for surgical care in LMICs. The goal of this paper is to summarize the available literature about surgical physicians in LMICs and to describe ongoing initiatives to supplement the existing surgical workfor
