Climate change is likely to have severe effects on water availability in Ethiopia. The aim of the present study was to assess the impact of climate change on the Gilgel Abay River, Upper Blue Nile Basin. The Statistical Downscaling Tool (SDSM) was used to downscale the HadCM3 (Hadley centre Climate Model 3) Global Circulation Model (GCM) scenario data into finer scale resolution. The Soil and Wate

The pathophysiology of sepsis-associated encephalopathy (SAE) is complex and remains incompletely elucidated. Dysregulated reactive oxygen species (ROS) production and mitochondrial-mediated necrotic-apoptotic pathway have been proposed as part of the pathogenesis. The present study aimed at analyzing the preventive effect of the free radical scavenger edaravone on sepsis-induced brain alterations

This article presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review reveals that theoretical calculations, measurements in full-scale rooms and simulations with validated lighting programs indicate that an energy intensity of around 10

PURPOSE OF REVIEW: A time-related negative trend in male reproductive function has been suggested. It has been hypothesized that this is due to exposure to chemicals interfering with the action of sex hormones. Also a negative effect of phytoestrogens on male fertility has been postulated. This review aimed to review the epidemiological evidence of deteriorating male reproductive function and summ

Recent climate change predictions suggest altered patterns of winter precipitation across the Arctic. It has been suggested that the presence, timing and quantity of snow all affect microbial activity, thus influencing CO2 production in soil. In this study annual and seasonal emissions of CO2 were estimated in High-Arctic Adventdalen, Svalbard, and sub-Arctic Latnjajaure, Sweden, using a new trace

The magnetic field, the sun, the stars and the polarization pattern of visible light during twilight are important cues for orientation in nocturnally migrating songbirds. As these cues change with time and location on Earth, the polarization pattern was put forward as a likely key reference system calibrating the other compass systems. Whether this applies generally to migratory birds is, however

This paper presents a digital hardware implementation of a novel wavelet-based event detector suitable for the next generation of cardiac pacemakers. Significant power savings are achieved by introducing a second operation mode that shuts down 2/3 of the hardware for long time periods when the pacemaker patient is not exposed to noise, while not degrading performance. Due to a 0.13-mu m CMOS techn

On-chip enzyme reactors are often used in medical/pharmaceutical analysis due to their inherent advantages, such as high sample throughput, low reagent consumption, stability, reproducibility and low cost. The present work describes a different application of such microreactors, namely, elimination of interfering ascorbate signals in glutamate monitoring using ascorbate oxidase modified silicon ch

Popular Abstract in Swedish Olika rapporter har fastslagit att de traditionella svenska folkrörelserna (såsom arbetarrörelsen och frikyrkorörelsen) tappar medlemmar. Istället för att ansluta sig till ett politiskt parti eller en kyrka söker sig politiskt eller religiöst intresserade individer till nya, individualiserade, former av engagemang. Denna avhandling studerar en grupp män och kvinnor somVarious reports have stated that the traditional Swedish popular movements (e.g. the Workers movement and the Free church movement) are loosing ground. Instead of joining a political party or a church, politically or religiously active individuals are said to seek out new and individualized ways of being involved. This thesis studies a number of men and women that persist in being communally invo

Popular Abstract in Swedish Nematofaga svampar förekommer inom många grupper i svampriket och har den gemensamma förmågan att döda nematoder (millimeterstora rundmaskar) och använda dem som näring. Vissa arter är obligata parasiter, medan andra är fakultativa saprofyter, vilket innebär att de förutom att parasitera nematoder lever av dött organiskt material. Dessa svampar har, sedan de upptäcktes Nematophagous fungi possess various mechanisms for infecting nematodes, and are either obligate parasites or facultative saprophytes. Nematophagous fungi have a potential as biological control agents against plant- and animal-parasitic nematodes. Generally there has been little success in using these fungi in such a way, and one reason might be that too little is known about the ecology of the nem

This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculat

A statistical study of data containing observations of process and quality variables from the SCA paper mill in Munksund, Sweden, is presented. The emphasis in this analysis has been on modelling the laboratory collected paper quality variables by means of the data available on-line, during production. The primary tool for prediction, or estimation at non observed time instants, of variables was

For years, it is an actuality in the poultry processing industry, that the body and the cardiovascular system of the chickens are not strong enough due to the shortened rearing time. This induces, that the quality of the chicken breast is not appropriate for selling, since during the processing procedure, frequently blood spots appear inside the meat. These damaged parts need to be removed, causin

We discuss the possibility of colour rearrangement in {Mathematical expression} events, i.e that the original colour singlets {Mathematical expression} and {Mathematical expression} may be transmuted, for instance, into new singlets {Mathematical expression} and {Mathematical expression}. The effects on event properties could be quite large if such a rearrangement would occur instantaneously, so t

Follicular fluid (FF) acts as a vehicle for paracrine signalling between somatic cells of the follicle and the oocyte. To investigate changes in the protein composition of FF during ovulation, we conducted a prospective cohort study including 25 women undergoing fertility treatment. Follicular fluid was aspirated either before or 12, 17, 32 or 36 h after induction of ovulation (five patients per t

Increased awareness regarding nutrition, environmental sustainability, and animal welfare has sparked a trend to shift away from animal proteins. The phenomenon is referred to as the protein shift and has resulted in a higher demand for alternative protein sources. This dissertation aims to study potential opportunities and challenges of using recombinant food proteins expressed in Escherichia col

The aim with this Master’s Thesis work was to conduct research about different available authenticators, as well as implementing a multi-factor authenticator into the currently used login-application. The research included biometric authentication technologies, and investigation of how to implement these to create a highly secure and customizable multi-factor authentication for My Axis-accounts fo
