BACKGROUND: Situational needs of health care facilities inform the optimal allocation of resources and quality improvement efforts. This study examines surgical care delivery metrics at a tertiary care institution in Liberia. METHODS: We retrospectively reviewed operative and ward logbooks from January 1 to December 31, 2012. Data parameters included patients' age, diagnosis, procedure, mortality,
Aims: The roles of the diverse populations of micro-organisms responsible for biodegradation of organic matter to form methane and carbon dioxide are rudimentarily understood. To expand the knowledge on links between microbial communities and the rate limiting, hydrolytic stage of two-stage biogas production from energy crops, this study was performed. Methods and Results: The process performance.
BACKGROUND: Consumption of soluble dietary fibre is correlated with decreased postprandial glucose and insulin responses and hence has beneficial effects on the metabolic syndrome. AIM OF THE STUDY: To investigate the effects on postprandial glucose, insulin and triglyceride concentrations of meals enriched with soluble dietary fibres from oats, rye bran, sugar beet fibre or a mixture of these thr
The aim of the present study was to investigate seasonal and spatial patterns of soil oxygen consumption, nitrification, denitrification and fluxes of dissolved inorganic nitrogen (DIN) in a tidal salt marsh of the Lagoon of Venice, Italy. In the salt marsh, intact soil cores including overlying water were collected monthly at high tide from April to October in salt marsh creeks and in areas cover

Materials and methods: The study was closed in June 2006 with 750 randomised patients. Radiation therapy-rel
Species composition affects the carbon turnover and the formation and emission of the greenhouse gas methane (CH4) in wetlands. Here we investigate the individual effects of vascular plant species on the carbon cycling in a wetland ecosystem. We used a novel combination of laboratory methods and controlled environment facilities and studied three different vascular plant species (Eriophorum vagina
Electroconvulsive therapy (ECT) is a very efficient treatment for severe depression. However, cognitive side effects have raised concern to whether ECT can cause cellular damage in vulnerable brain regions. A few recent animal studies have reported limited hippocampal cell loss, while a number of other studies have failed to find any signs of cellular damage and some even report that electroconvul
Popular Abstract in Swedish Blodkärlen har till uppgift att distribuera syre och näring till kroppens alla celler, samt att borttransportera slaggprodukter som sedan bildas efter nyttjandet. Dessutom förmedlas en rad signalsubstanser till kroppens vävnader via blodcirkulationen. Eftersom mängden cirkulerande blod är begränsad är det viktigt att blodkärlen, bestående av artärer som för blodet från This thesis aims at characterizing the endothelin (ET) receptors in different vascular beds of man and rat. The ET-A receptor was shown to be the only contractile ET receptor present in all vascular regions, with the exception of the rat mesenteric vein where a weak ET-B receptor-mediated contraction was seen. Treatment with antisense oligodeoxynucleotides to the ET-A receptor mRNA during organ cu
Due to increasing oil demand and serious global warming, a green power generation system is urgently requested in transportation. Electric/hybrid vehicles (EV/HEV) have been considered as a potential solution with great promise in achieving high energy/power efficiency and a low environmental impact. The important electric and electronic equipment in EV/HEV are the battery, inverter and motor. How
Popular Abstract in Swedish Telomerer är en specialiserad DNA-protein struktur som finns i slutet av den linjära kromosomen. Trots att den telomera regionen inte innehåller några gener anses den vara oumbärlig för kromosomernas överlevnad. Telomererna skyddar kromosomerna från nedbrytning orsakad av enzymatiska attacker. Kromosomer utan telomerer har dessutom visats vara ytterst reaktiva och fuserThe telomeres, the physical ends of the chromosomes, consist in various species of short simple tandem repeats which are extended by telomerase. The Drosophila melanogaster telomeres, which instead are elongated by retroposons, are an exception. In Chironomus pallidivittatus and Chironomus tentans the telomeres contain 340/350-bp tandem repeats in blocks up to 200 kb in size. The structure of the
The basic hypothesis is that mind is an emergent property of the processes that produce natural language expressions. The shape of the mind of a particular person can be discovered through the mechanisms forming the corresponding language space. Although covered by textual surface properties, this space is approachable with VERTEX, which is a new version of Perspective Text Analysis (PTA). Due to
Most computers today are embedded, i.e. they are built into some products or system that is not perceived as a computer. It is highly desirable to use modern safe object-oriented software techniques for a rapid development of reliable systems. However, languages and run-time platforms for embedded systems have not kept up with the front line of language development. Reasons include complex and, in
Sulfur-containing compounds are used as rescue agents to protect normal tissue from the toxic side effects of cis-[PtCl2(NH3)(2)] (cisplatin) without affecting its anti-tumour activity. Reactions of the model complexes [Pt(dien)Cl](+) (1) and [Pt(dien)(GSMe)](2+) (2) (GSMe = S-methylglutathione) with the rescue agents glutathione (GSH), thiourea, thiosulfate, and diethyldithiocarbamate (DDTC) have
Popular Abstract in Swedish Alzheimers sjukdom och vaskulär demens är de vanligaste orsakerna till demens hos äldre, ett tillstånd som i takt med den ökande åldrade befolkningen kommer att innebära ett allt större lidande och en alltjämt ökande ekonomisk belastning. Direkta och indirekta kostnader för vård och omsorg av demenspatienter uppgår sannolikt till ca 40 miljarder kronor om året. Detta ärDementia is a state of permanent loss of cognitive function, most commonly affecting the elderly. With a rapidly growing aged population, the spectrum of disorders that lead to dementia is exerting an ever-increasing toll on patients, families and society alike. The most common dementing disorders are Alzheimer's disease and vascular dementia. Although Alzheimer's disease is very common and was de
In precision hard turning, tool flank wear is one of the major factors contributing to the geometric error and thermal damage in a machined workpiece. Tool wear not only directly reduces the part geometry accuracy but also increases the cutting forces drastically. The change in cutting forces causes instability in the tool motion, and in turn, more inaccuracy. There are demands for reliably monito
Popular Abstract in Swedish I denna avhandling har jag undersökt hur man kan utöka det dynamiska omfånget utan att öka noggrannheten i en analog-till-digital omvandlare med en flyttalsliknande lösning. Den valda lösningen går ut på att man förstärker en analog insignal med flera oberoende analoga förstärkare med skilda förstärkningar. Sedan väljs den förstärkare som ger den starkaste utsignalen sTo deal with the wide dynamic rage necessary for a radio receiver or corresponding applications, but to avoid impractically high resolution at high data rates, the approach of using a floating-point analog-to-digital converter (FP-ADC) has been investigated. This approach de-links the dynamic range with the resolution, and a very wide dynamic range can be achieved by an ADC with a moderate resolut
Abstract Nilsson, Nils-Erik, Write in Your Own Words: A Study of Learning Processes in Research Report Writing in School. The thesis examines sixty pupil texts produced in the school activity called pupil research at secondary level of a Swedish school where this activity was scheduled one day per week. The purpose of this thesis is to develop knowledge about the writing done by pupils under the
Dissemination of risk information is ubiquitous in contemporary society. We explore how individuals react in everyday life to health-risk information, based on what they report in personal interviews. Health-risk information was without exception recognized as unstable and inconsistent. This conformity, however, did not extend to the narratives regarding how health-risk information should be handl
Migratory strategies of birds require complex orientation mechanisms, morphological adaptations, and life-history adjustments. From an evolutionary perspective, it is important to know how fast this complex combination of traits can evolve. We analyzed mitochondrial control-region DNA sequences in 241 blackcaps (Sylvia atricapilla) from 12 populations with different migratory behaviors. The sample
