Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

This study has been made to evaluate if there is a significant difference between non-estral intact versus ovariohysterectomized queens in their production of estradiol after exogenous gonadotrophin-releasing hormone stimulation. The purpose is to find a tool, which can help to diagnose if a free-roaming queen is already ovariohysterectomized or not. There are also other situations where this tool could be useful, for example to diagnose the ovarian remnant syndrome. Previous studies in bitches have shown that GnRH-stimulation is an excellent tool to diagnose the presence of ovaries in the bitch. Eleven ovariohysterectomized and eleven intact queens have been included in this study where we have analyzed plasma estradiol and progesterone concentrations before and after a single intramuscular injection of the GnRH agonist buserelin (Receptal?).

Both the Commission and the Community Courts have on several occasions stated that a concentration that will cause the creation or strengthening of an oligopoly under certain circumstances might cause what?s referred to as a collective dominant position in the market. The concept of collective dominant position has gained a lot of criticism for being poorly defined and thereby create an uncertainty. The Commissions approach when applying the concept has also gained criticism for its lack of consistency. As a consequence of the Court of First Instances (CFI) decision in the case Airtours v.

Studien analyserar vad arbetsgivare har för uppfattningar beträffande personer med ADHD på en arbetsplats. Semistrukturerade intervjuer har använts som datainsamlingsmetod. Urvalet består av sju arbetsgivare inom den privata sektorn. Studien har inspirerats av den fenomeno-grafiska ansatsen, där olika uppfattningar om ett fenomen står i centrum. Teoretiska analysbe-grepp för den här studien är social kategorisering och den medicinska och sociala modellen kopplat till funktionsnedsättningar.

 Background: Self-injury can be defined as deliberate harm one's own body without conscious intent to commit suicide. These patients need skilled care. Purpose: Illuminate nursing staff attitudes and treatment of patients with self-injury behaviour for individuals diagnosed with borderline personality disorder. Method: A general literature study has been made. Based on the objective was a literature search in various databases with ten relevant articles were selected and reviewed.

Neuropsykiatriska funktionsnedsättningar är idag lättare att diagnostisera och det är vanligare att barn och ungdomar i skolan vet om att de lever med en diagnos som till exempel Attention deficit hyperactivity disorder (mer känt som ADHD), eller Aspergers syndrom. Trots att dessa diagnoser blir allt vanligare, finns det ett ökat behov för kunskapen om dem.Syftet med denna uppsats var att studera barn och ungdomar med neuropsykiatriska funktionsnedsättningar, och framförallt studera deras liv i skolmiljö. Att få mer förståelse för hur barn och ungdomar har upplevt skolan och relationen till sina lärare, men även hur de upplevt de hinder och möjligheter deras neuropsykiatriska funktionsnedsättning medfört var i fokus. Metoden i denna studie var semistrukturerade intervjuer med 6 ungdomar, deras föräldrar och lärare. Frågorna har handlat om hur ungdomarna sett på diagnosen, livet med den och även hur de klarat av skolgången med sin funktionsnedsättning.

IBS patients experiences of eating the low FODMAP-dietIrritable bowel syndrome (IBS) is a common, functional gastrointestinal tract disorder. The disease is benign but may cause much suffering for the individual. The treatments available are used to relieve symptoms. One nutrition therapy is to exclude fermentable oligo-, di-, monosaccharide and polyols, so callde FODMAPS, from the diet. This diet is proven successful and even significantly better than the standard nutrition advice for IBS.

The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).

Our work is based on a mathematics test which the students accomplished, interviews with student and teachers who are working on this program and the current literatures. The purposes of this work are to search the importance and the effect of the languages understanding in students learning of mathematic in the Individual high school curriculum. In total, sex students and three teachers took part in our study. Tow of the students is mother tongue language student and the remains are second language student. Our study should answer tow important questions:? Do the student in the Individual high school curriculum have the fundamental knowledge in mathematic?? How does the understanding of Swedish language effect in the understanding of the mathematic problems and in the students results in mathematic test?In order to answer those questions, the students have to complete a mathematic test that consists of four parts.

Personer som genomgått en traumatisk händelse befinner sig i riskzonen för att utveckla post-traumatic stress disorder (PTSD), som innebär en stor livsbegränsning och ett stort lidande. Dagligen möter hälso- och sjukvårdspersonal personer som ännu ej diagnostiserats och det är därför av vikt att kunna identifiera PTSD-symptom. Syftet med litteraturstudien var att undersöka samband mellan olika trauman och PTSD-symptom enligt diagnostiseringssystemet DSM IV. Studien grundades på en deduktiv ansats och resultatet bestod av 15 vetenskapliga artiklar som granskades. Resultatet behandlade DSM IV:s tre symptomkluster: re-experience/intrusion, avoidance och hyperarousal.

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

The study's purpose was to get a picture of what a number of class teachers know about and their views on the concept of working memory and working memory training and whether this affects their working and teaching in the classroom. The study is based on qualitative interviews and classroom observations and the theoretical perspectives that the study is based on two: didactic perspective and the socio-cultural perspective. The results of my study show that the class teachers' views and use of the concept of working memory is limited, even if they unknowingly working on parts of it in their teaching. All classroom teachers in my study term difficulties that can arise for students as concentration difficulties, which according to previous research can count towards deficiencies in working memory. All of the respondents in this study believe that it is mostly special education teacher who trains working memory, and that they themselves do not have that knowledge. They also believe that the classroom environment is important for all learning. Common to all respondents consider that the topic is important and would like to have more knowledge of how they can help and support pupils with poor working memory. As a special education teacher and teacher you often meet students who have trouble concentrating, and because of this may be difficult to absorb knowledge as when reading.
