Högtempererat borrhålslager för fjärrvärme
The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.
Alzheimers sjukdom : anhörigas känslor vid en förändrad livssituation
Alzheimer's disease is the most common form of dementia. The individual who fall ill can be in an age between 40-65 years old. When dementia affects individuals at this age, many relatives take their responsibility for taking care of them at home for a long time.The aim of this study was to illustrate emotions relatives experienced when a close family member's suffering from Alzheimer's disease. The study was intended to show relatives emotions, and therefor four self-biographies were chosen to read. The method used to analyze was a narrative literature review.
Hur vuxna med permanent ileostomi upplever sin livskvalitet
Having an ileostomy can affect the quality of life. Quality of life is defined by Siri Naess as being active, relating well to others, having self-esteem and having a basic mood of happiness. The nurse?s task is to focus on the stoma care and work in a holistic way. The aim of the study was to describe how adults with permanent ileostomy experience their quality of life.
Identifiering av infektion i sår, en litteraturstudie
Regardless of what discipline nurses work in, wound care is one of the tasks. Caring for wounds involves early detection of signs of infection, in order to avoid complication. Wound infection extends suffering for the patient and causes unnecessary costs for society. The aim was to describe how nurses can identify infection in wounds. Method: The design of the study was a literature review, where13 scientific articles were examined and analyzed.
Magomvridning :
The purpose of the study was to review the current veterinary literature regarding gastric dilatation and volvulus (GDV) considering pathophysiology and treatment, and to evaluate the operative technique (incisional gastropexy) used during the years 2005 and 2006 at the University Animal Hospital (Universitetsdjursjukhuset), SLU, Uppsala, Sweden.
GDV has a complicated pathophysiology which foremost effects the circulatory system. Progress is often acute and it is not unusual that patients are affected with shock. The initial treatment targets to alleviate the shock by fluid therapy and decompression of the stomach. There is a high risk of recurrence in the long term perspective unless the stomach is surgically fixated by gastropexy. The study describes two different techniques for gastropexy; incisional gastropexy, and funduspexy.
Long term complications were rare among the patients that were treated surgically, while about half out of the eighteen dogs that undergo surgery do experience complications of various severity in the short term..
Likheter och skillnader i fysisk smärta hos kvinnor från olika kulturer. En systematisk litteraturstudie.
Samhället idag blir alltmer mångkulturellt. Syftet med föreliggande studie var att undersöka uppfattningar om smärta och smärtuttryck hos kvinnor från olika kulturer, från såväl ett patient- som ett vårdpersonalperspektiv. Teoretisk referensram för litteraturstudien var Joyce Travelbees teori om mellanmänskliga aspekter i omvårdnaden. Litteraturstudien är baserad på Forsberg och Wengströms (2003) metod för att genomföra systematiska litteraturstudier. Resultatet mynnade ut i en rad skillnader och likheter som har bearbetats i olika kategorier där de viktigaste resultaten pekade på att det finns både skillnader och likheter i smärtupplevelse och smärtintensitet hos kvinnor från olika kulturgrupper.
Etiologi och patogenes för benign prostatahyperplasi hos hund
This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.
Hur patienter med psykisk oh?lsa upplever m?tet med sjuksk?terskor : En litteratur?versikt
Bakgrund: Psykisk oh?lsa inkluderar b?de omfattande psykiatriska tillst?nd som p?verkar personens vardag samt lindrigare besv?r. Bristf?llig kommunikation och interaktioner kan inneb?ra ?kad stigmatisering, f?rs?mrad ?terh?mtning och minskad tilltro. Detta samtidigt som att empati och lyh?rdhet bidrar till st?djande delaktighet samt trygghet.

Alternativ splicing: en process som medför att flera olika mRNA-transkript bildas från individuella gener
This review article presents the splicing process during messenger RNA maturation and how it is regulated by different Cis-regulatory RNA-sequence elements and splicing factors. A more detailed description of the process alternative splicing and its importance to the function of genes from the model organism Arabidopsis thaliana is also given. A single eukaryotic gene can by the process alternative splicing (AS) give rise to a number of functionally mature mRNA-molecules, which in turn encodes for structurally and/or functionally different proteins. During the course of evolution, the process alternative splicing has thus shown to be effective in increasing transcriptome and proteome diversity of most eukaryotic organisms. This suggests therefore that the dominant theory in molecular biology, a gene encodes for a protein, needs to be corrected.

By having interviewed various teachers through surveys we have received answers to their concerns about the diagnosis, treatment and the importance of continuous training of teachers on students? mathematics difficulties.
Motion mot depression. En litteraturstudie om fysisk aktivitet somhälsofrämjande intervention för personer med depression
The purpose of this study is to investigate the effect of physical activity for people suffering from depression and which nursing interventions nurses can do to make this patients start to exercise. The method used, is a review of articles from Ci-nahl, Cochrane, Elin, PsycInfo, Pubmed and Science Direct, which were analyzed according to Polit och Hunglers criteria for scientific research. The result from the nine studies shows that physical activity has an antidepressive and anxiety reduc-ing effect. Interventions emerged is supporting, encouraging, activating and teach-ing about physical activity as health-promoting measure. Conclusion: Nurses can as an intervention introduce exercise as complementary treatment for people suffering from depression.
Methane emissions from Swedish sheep production
The quantity of methane emissions from sheep depend on several factors, for example, the composition of the diet, feed quality, the age of the animals, time of the day and maybe also breed and sex. A comprising literature review was made about which factors that affect the size of emissions. In addition, a questionnaire was sent to two farms, one with a more intensive production system and another with a more extensive system. Inventories of the two farms were made; the rest of the data needed to conduct the study was taken from literature and other sources. Meat produced at the more intensive farm caused emissions of 0.4 kg of methane per kg of bone free meat and the more extensive farm caused emissions of 0.9 kg methane per kg of bone free meat.
Hästens, Equus caballus, termiska komfort - hur kan djurskyddskontrollanter bedöma hästens välfärd?
This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature;
? How can the horse maintain thermoregulation?
? Is there a risk of suffering when horses wear a blanket?
? Is there a risk of suffering when horses do not wear a blanket?
? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket?
My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.
Allmänsjuksköterskans problematik kring bemötandet av den HIV-positiva patienten i den somatiska vården
The number of HIV- positive is increasing all over the world and it's very likely to meet these patients as a nurse. The interaction between the nurse and the patient is characterized by experience and knowledge and at the same time the nurse is expected to act professionally. The purpose of this literature review is to investigate the nurse's complex of problems regarding the treatment of the HIV- positive patient by exploring the attitudes against HIV among nurses and how the nurse can maintain the integrity of the HIV- positive patient. Antonovsky's salutoqenic model, sense of coherence, has been used as theoretical frame. From 14 articles five topics have been found that influence the nurse's attitudes against HIV-positive patients.
