Produktion av Pyrolysolja från kvistrejekt

Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting.  Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.

"Arbetslöshetssjukan": en kvalitativ studie av arbetsförmedlares upplevelse av arbetslösas mående

The purpose of this study was to examine how the personnel of the Employment Office in Malmoe interpret the emotional situation and health of unemployed individuals. We also wanted to examine if and how the personnel work with these aspects. In relation to this we found it very interesting how the personnel dealt with the responsibilities of power, hierarchy and how subordination afflicts the unemployed. Our main questions were: Are the previous studies results confirmed by the response the personnel of the Employment Office give about the difficult situation among unemployed individuals? Which factors do the personnel at the Employment Office consider the main causes of negative emotional situations among the unemployed? How do the personnel deal with the emotions of the unemployed? How does the important responsibilities of power affect the relationship between the personnel and the unemployed? Which effects/impacts from current political changes are the personnel able to see on the situation of the unemployed? We interviewed eight people working at the Employment Office in Malmoe.

Dialog i samförstånd : Från istappar till samarbete; faktorer som påverkat dialogen mellan Arlanda och kranskommunerna

Arlanda är Sveriges största internationella flygplats och har en stor betydelse när det kommer till jobb, näringsliv, kunskap, turism, kultur och därmed hela Sveriges välfärd. Flygplatsen ligger i Sigtuna kommun och runt omkring Arlanda ligger ytterligare tre kommuner; Vallentuna, Knivsta och Upplands Väsby.  Alla dessa arbetar aktivt med åtgärder för en hållbar utveckling av sina organisationer.Kommunerna och Arlanda har tre huvudsakliga gemensamma intressen som samverkar och är beroende av varandra.  För att tillsammans organisera, strukturera och försöka hitta gemensamma hållbara lösningar på de problem och möjligheter som uppstår runt intressena har kommunerna och Arlanda en väl utvecklad dialog.Dialogen idag beskrivs som god och samtalsklimatet positivt. Kommunerna är delaktiga i Arlandas utveckling och samarbete sker i flera forum. För drygt tio år sedan var bilden en annan. Samtalsklimatet uppfattades som kyligt, verksamheten var sluten och det togs ingen hänsyn till vilken påverkan man hade på omgivningen.Litteratur som rör dialog mellan en organisation och dess intressenter poängterar ofta vikten av att man förstår varandra och delar uppfattning om vad organisationens ansvar består i om relationen ska vara värdefull.  För att få en större kunskap om hur det samförståndet ser ut i Arlandas fall har en rad intervjuer med representanter från de olika kommunerna samt Arlanda genomförts.

Anestesi av ödlor

The anatomy and physiology of reptiles and mammals are in many ways different, and will therefore possibly complicate anesthetic administration. Lizards are ectothermic and one should keep in mind that a decrease in the lizard?s environmental temperature may result in reductions in anesthetic metabolism. Respiratory depression is a profound problem because lizards lack a diaphragm, making inhalation and expiration completely active processes. This, in combination with cardiac shunting and breath holding makes the effects of anesthesia unpredictable.

Elevers värderingar om bedömning och uppfattningar om betyg : En kvantitativ studie om betygskriterier, planering och betyg

AbstractThe purpose of this study was to investigate students' perception of their grades in relation to the grading criteria in physical education. To investigate this used issues: how values and experience rating criteria? How do students their teachers' planning of lessons? How do students grading assessment in physical education and what they believe is important? The method used was a questionnaire with closed questions. The answers were given on a six-point scale, ranging from 1 = "not true" to 6 = "totally agree". In a qualitative analysis of the quantitative material.

Dogs on the move : a study of the travel habits of Swedish dogs and their owners? awareness of infectious diseases.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :

Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

Patientens informations- och kommunikationsbehov vid cytostatikabehandling

Introduction Malignant lymphoma is the most common haematological blood cancer diagnosis. In spring 2013 a questionnaire was handed out to patients with various haematological malignancies. The results showed that the patients requested more verbal and written information about their disease and treatment. Providing information about chemotherapy and how it affects the patient's quality of life is part of the nursing care. Communication between nurse and patient is very important to share experiences and knowledge with each other Aim The aim is to describe the information and communication patients with malignant lymphoma demand, based on their own experience, in meeting with the nurse before and during curative chemotherapy treatment at a haematology outpatient clinic.

Returflöden inom e-handel av kläder

The purpose of this thesis is to find out the reasons and perhaps some answers to the problem as we see it, the sickness benefit expiration of those who experience this. By this said we have also taken into account the different laws and adjustments in the long-term sickness benefit, but also major reformation of the security net in the Swedish society. The efficiency of the law on passive long-term sickness absence was added in July 2008, but was later in January 2010 supplemented. The purpose of this law wasn?t only to reduce the long-term sickness absence but also to reduce exclusion.

Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)

Peat  lands  are  a  great  potential  resource  for  increased  forest  growth  in  Sweden, there  are  approximately  6.5  million  hectares  of  peat  lands,  whereof  around  70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste  land.  There  are  over  200  000  hectares  of  peat  land  that  is  already  drained and  wooded,  and  that may  be  suitable  for  fertilization.  Forest  production  on  peat soils  usually  requires  drainage  and  fertilization.  Dewatering  requires  ditching  the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The  purpose  of  this  work  was  to examine  the effects  of  potassium  fertilization  on the  growth  of  spruces  that  were  planted  on  drained  peat  land  and  how  different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance  transport  in  the  tree.  Potassium  is  also  important  for  the  carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter  resistance  of  many  species.  Potassium  is  not  found  in  any  organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was  left  without  fertilization.  All  plots  that  were  fertilized  with  potassium  grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality  estimation  of  wetlands  after  ditching  (dikningsbonitering).  The  plot  with most  potassium  produced  after  fertilizationaproximately  in  level  with  theoretical estimations.  Key  words:  Peat  land,  Fertilization,  Ditching,  Growth,  site  quality..

Nilsson, P. (2005). Which manager qualities can be related to a health promotive leadership? A questionnaire study among managers at hospitals. (41 p.)AbstractPeople?s working life and individual health can be seen as strongly related to each other because people spend the most of their adult lives at their places of work.

Intuition i beslutsfattande : En studie om det intuitiva beslutsfattandet och dess påverkande faktorer vid Akademiska sjukhuset i Uppsala

Managers operating within the dynamic society of today are said to rely on intuition when effective and quick decisions are to be made. This skill or phenomenon has aroused an interest within the academic world of management whom has explored intuition, its relation to decision making and its influencing factors, especially in the private sector. Intuitive decision making is however not isolated solely to this sector but also involved in decision making associated to the public sector. Therefore, the aim of the thesis is to investigate whether managers at the hospital Akademiska in Uppsala involve intuition in decision making and to what extent the factors time, amount of information, individual experience and decision complexity influence the intuition.The theoretical framework includes academic research regarding how intuition and rationality affect decisions, the concept of intuition and factors influencing the intuitiveness of decision making. Furthermore the theoretical discussion explores intuition connected to leadership, negative aspects of intuitive decisions and a comparison between different factors that separates public and private sector in terms of decision making.

Swedish municipals schools have been given an assignment to convey basic values to pupils. The assignment is to bring up the pupils through transmitting and developing a heritage such as values, traditions, language and knowledge. Together along with the lasting knowledge which constitutes the community frame of reference everybody needs. There by is the purpose of this study through a qualitative method to investigate how the schools assignment to create a community national identity of the pupils is interpreted by the teachers in introduction classes. Even how the teachers in this study response to ?Swedish? culture by presenting and educate the pupils in this.

Tidig postoperativ övervakning av smådjur : förekomst av standardiserade rutiner

Background. Anesthetic-related death in small animal anesthesia is about ten times more common than in human anesthesia. Recent research identifies the early postoperative period as particularly risky and highlights the need for regular and careful monitoring of the veterinary patient during this period. Objective. The aims of this study were to investigate whether there are standard procedures in terms of regulated routine patient observations and record-keeping during the early postoperative period at Swedish veterinary clinics, and if there are any guidelines for monitoring the veterinary patient during recovery. Methods. A small survey including ten Swedish veterinary clinics was carried out as well as a literature review. Results.
