Snusets effekter på aeroba processer och energiomsättning under fysiskt arbete

Syftet med föreliggande studie var att undersöka effekterna av ett längre uppehåll från tobaks- och nikotinbruk på maximal aerob effekt och energiomsättning under submaximalt arbete hos regelbundet snusande personer. Metod23 snusare (18 män, 5 kvinnor) undersöktes före och efter >6 veckors uppehåll från snus (SSP). Försökspersonerna genomförde ett stegrande submaximalt arbete på cykelergometer, ett maximalt löptest och ett uthållighetsarbete bestående av 60 minuter cykling på 50 % av VO2max. Syreupptag (VO2), ventilation (VE), subjektivt skattad ansträngning på Borgs RPE-skala (RPE), hjärtfrekvens (HF) och blodtryck (BT) mättes. Blodprov togs för analys av kotinin, laktat [HLa], blodglukos och fria fettsyror (FFA) i vila och under arbete. ResultatSubmaximalt VO2 och energiomsättning påverkades inte av >6 veckors uppehåll från snus. VE, respiratorisk kvot (RQ), blodglukos och RPE var oförändrade under det stegrande submaximala arbetet.

Bayesisk filtrering i syfte att motverka spam : En studie om bayesisk filtrering i olika programvaror

Ett konstant problem med e-post är mängden skräppost som skickas dagligen och bidrar till en osäkerhet bland hemanvändare samt medför stora kostnader för företag.

The rabbit as an animal model in dental implant research : with special reference to bone augmenting materials

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Vad kan få en anställd att tappa tråden?

Mobiloperatörer har under en längre tid haft en stark fokusering på konsumentmarknaden och i flera avseenden försummat företagsmarknaden för mobila tjänster. Detta har till viss del förändrats under de senaste åren i takt med utvecklingen av mobil e-post som primärt riktas mot företag och organisationer. Vi har uppmärksammat denna förändring och därmed intresserat oss för organisationers användning av mobila tjänster. En marknad som vi tror kommer att expandera än mer under de kommande åren. Syftet med vår uppsats är att empiriskt undersöka vad som påverkar anställdas användning av mobila tjänster.

Etiken och rummet : - om det sociala arbetets etik i rumsliga sammanhang

In Sweden there is an integration policy and a policy for national minorities. The integration policy aims to integrate newly arrived immigrants (nyanlända invandrare), whereas the minority policy aims to maintain and strengthen the rights of the national minorities. The national minorities are though, at times, included into the integration policy, even though they hold a minority status in Sweden. This paper aims to, through discourse analysis, investigate the research question: ?how is the content of integration referred to, when it is related to immigrants, contra when it is related to national minorities?.

Antikroppsstatus mot kattpest hos lejonen i Kolmårdens Djurpark :

The lions at Kolmårdens zoo are vaccinated against Feline Panleukopenivirus (FPV). In 1994 there was an outbreak among the lions at the zoo of FPV disease. A retrospective study has been made to measure the antibodytiters in vaccinated lions and lions that lived during the outbreak. An ImmunoPeroxidase Monolayer Assay (IPMA) was used to analyze the titers in the sera from the lions. Lions were divided into five groups. Group 1, 2 and 3 contained lions vaccinated one, two and three times respectively (a total of 40 animals). The lions of Group 4 were born in 2004 (six lioncubs) and were vaccinated according to different regimes and the changes in antibodytiters were followed as respose to vaccination during the spring 2005.

Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin

The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..

En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

Herakleitos logos : Om några tolkningar av filosofins grundbegrepp

The philosopher Heraclitus has been renowned for a great amount of time. Despite that fact the remaining fragments of his work have just recently been assembled to the composed form they have today. Among these fragments there are a couple of terms that stands out amongst others; one of them is the term logos. The main focus of this thesis is devoted to the mystery and usage of the term logos, which comes into a great display in fragment number 50.The ambition of the thesis is to evaluate and compare three interpreters? readings of Heraclitus while having a close focus on his usage of the word logos in fragment 50.

Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

Glukos och leucin som potentiellt hjälpmedel i återuppbyggandet av muskelglykogen efter hårt arbete hos travhästar

The aim of the project was to study the effect of oral administration of glucose and leucin on the resynthesis of muscle glycogen after intense exercise in Standardbred trotters. In a crossover design, 11 Standardbred trotters performed a standardized exercise test on two occasions in order to deplete muscle glycogen. The exercise test comprised a warm up period, 7 repeated bouts of exercise on an uphill 500 m slope, and a recovery period. After the exercise test horses received: 1) a solution of glucose and leucine via a nasogastric tube at 0 minutes and at 240 minutes post exercise and a single bout of glucose at 120 minutes post exercise or 2) water (placebo) at 0, 120 and 240 minutes. Blood samples for measurement of glucose and insulin concentrations were collected at rest, when the horses returned to the stables directly after exercise and throughout the 6 hour recovery phase. During the first recovery hour, samples were collected every 15 minutes and then every 30 minutes over the next 5 hours.
