Analys av klimatskärmens lufttäthet i ett småhus
Together with NCC and Sweco we measured the air-flow on a semi-detached house in Jönköping. When a pressure measurement is made, the house gets exposed to over- and under pressure. This is done in order to examine the houses climate shell. The climate shell of the semi-detached house we tested exceeded the required air thickness in BBR-2002, hence, measures have to be taken.This report also displays the importance of building air thick houses and what consequences a non air-thick house can have for the ones residing the house. A discussion of different measures is on for the addressed problems with the flow-measurement and the alternative construction-solutions.Furthermore we have described in this report of how to account for the performance of the air pressure, what kind of equipment we used and how we came up with the results.

Blodtrycksfall, pulstryck och lindriga kognitiva symptom - En polytom logistisk regressionsanalys
People live longer. There is a growing need to increase the knowledge of aging and of the need among the elderly for medical care in the near future. As a step towards meeting this need, a survey among the elderly in Skåne is made by the division of Geriatric Medicine in Malmö University Hospital. This survey is called Gott åldrande i Skåne, GÅS. A frequent decease among the elderly is Mild Cognitive Impairment (MCI).
The effect of low light intensities and red light on heart rate, blood pressure, respiratory rate and activity in dairy cows
Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.
Magnesiumintagets betydelse för blodtryck och magnesiumkoncentrationen i stickprov av urin, träck och blodplasma hos häst
The purpose of this trial was to evaluate the possibility to use sampling of faeces, urine and plasma, and measurements of blood pressure as methods of discovering hypomagnesemia in horses, as well as the application handiness of these methods. The most commonly used method of checking the magnesium status of a horse is to analyze samples of serum or plasma. The trial was of a switch-back design, in which the horses were used as their own controls. The animal material was five Swedish warm blooded trotters between six to ten years old, and weighing between 485-620 kg. The trial consisted of three periods that were two months each.
Barnens kunskaper : En empirisk studie av barnens kunskaper om hjärtat, blodet och blodomloppet
AbstractThis report aims, through interviews, observations and literature review to examine what some of the youngest children know about the heart, blood and bloodstream. The sample size was twenty children, half of them are at the age of three and the other half is at the age of six.The interviews showed that children at the age of six had better knowledge than children at the age of three, but one child knew that we have the blood corpuscle in the body. He was also the only one who mentioned the blood corpuscle of all children who participated in the research. Children at the age of three could not see the functional relationship between the blood and heart. One child who was six years told that the air we breathe goes directly in the heart from where the blood is circulating to the rest of the body, together with the food.Keywords: heart, blood, bloodstream, the body.
Prehospital vätskebehandling vid stort trauma ur en sjuksköterskas perspektiv : En systematisk litteraturstudie
The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.
Förebyggande djuromvårdnad mot post-anestetisk myopati hos häst
Post-anaesthetic myopathy (PAM) is a serious occasional complication of general anaesthesia in horses. It causes not only pain and suffering to the horse, but also suffering (trauma) to the owner with increased veterinary costs. In the worst case PAM can be fatal. The anaesthetic nurse must know which parameters have to be taken into consideration in the prevention of PAM, to be able to prevent it, and use that knowledge for the animals safety. The aim of this literature review was to investigate and make a presentation of the factors and measurements associated with PAM, with focus on how to monitor these measurements to prevent it from happening, and the advice a Veterinary nurse can give to the horse owner regarding this condition.
According to literature there a few factors that greatly increase the risk of PAM, these include- hypotension, periods less than 60 mmHg significantly increases the risk.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Whole fat versus low-fat dairy products for primary prevention of cardiovascular disease. A systematic review.Author: Josefine Lindqvist, Robin Järnmark, Mathilde OhlinSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2014-04-09BackgroundResearch indicates that dairy products seems to have a protective impact on the incidence of cardiovascular disease regardless fat content. Paradoxically the Nordic nutrition recommendations recommend an exchange of full fat dairy product to low-fat dairy products.ObjectiveThe aim of this review is to investigate whether the variation in fat content of dairy products have any bearing on the onset of cardiovascular disease. With regard to common risk markers for cardiovascular disease the outcome measures hypertension, hyperlipidemia and weight gain is examined.Search strategyThe searches were made in the databases Medline (23/1-14) and Scopus (6/2-14).Selection criteriaRestrictions: Human Studies, Adults, Randomized Controlled Trials, English.Data collection and analysisTwo RCTs were included. Validation of the separate studies was performed with SBU's review template for individual studies and GRADE was used for summarizing the evidence of outcome measuresMain resultsThe two included studies examined the outcome measures blood pressure, weight and blood lipids.
Medborgare, sträck ut din arm : Bloddonation och blodhandel i Folkets Dagblad 1985-1998
The purpose of this BA-study is to analyse articles about blood selling and blood donations in the Chinese daily newspaper People?s Daily between 1985 and 1998.With publications of popular scientific material, reports from rallies and portraits of blood donating ?heroes? etc., the People?s Daily, i.e. the Chinese Communist Party, actively addresses the underlying cultural reluctance to give blood by different means. People?s Daily and the CCP resolutely aims to transform negative Confucian and other traditional notions of losing blood into representations of courage, honour, duty, etc.
Blodets biopolitik : Heterosexuell hygien och män som har sex med män
Following the wake of the AIDS-catastrophe in the beginning of the eighties, homosexual men or 'men who have sex with men' (MSM) have been barred from donating blood throughout the planet. In this thesis I look into the different discourses at play in the context of creating the legal framework for blood donation in Sweden. Genealogically tracing the emergence of the category of MSM and mapping how the category is brought to use in contemporary negotiations on blood safety, I scrutinize how scientific truth is established within blood transfusion practice. I argue that the rationality of risk group exclusion is contingent on economical grounds, and that the foucauldian concept of biopolitics could productively be used to understand this rationality. In particular, the concept of the 'biopolitics of blood' can be employed in order to understand the reluctance from the involved actors to acknowledge the heteronormative consequences of the legal framework of contemporary blood donation..
The change of haemoglobin during blood donation, and an assessment of a photometrical method for non-invasive haemoglobin analysis
In Sweden, lowest acceptable haemoglobin levels in blood donators are 125g/L for women and 135g/L for men for a test sample taken in the beginning of the blood donation. Levels, which are 10g/L lower, are accepted if the sample is taken after the blood donation. Earlier studies show that the haemoglobin level decreases for a person that is lying down.The two aims of this study were to examine how much the haemoglobin levels change during blood donation and to examine if the photometrical instrument Pronto-7TM shows equivalent results to that of the established method Cell-Dyn Sapphire.In the study, 120 blood donors participated. Blood samples were taken in the beginning and in the end of the donation. Analyses by Pronto-7TM were done before and after the donation.The haemoglobin level decreased significantly during the blood donation.
Evaluation of a Flow Cytometry Method for Identifying and Quantifying Fetal Red Blood Cells in Maternal Blood
Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.
Surgical stress response in dogs diagnosed with pyometra undergoing ovariohysterectomy
The aim of this study was to investigate the intraoperative surgical stress response in dogs undergoing ovariohysterectomy and to compare acepromazine and medetomidine as premedications. 15 dogs diagnosed with pyometra were used in this study. Blood pressure and heart rate were used as parameters to measure surgical stress response. The surgery was divided into four phases. Phase 0 was the period 10 minutes before the skin incision, phase 1 was skin incision and opening of abdomen, phase 2 was manipulation of uterine horns, ligation and transection of mesovarium and phase 3 was ligation of cervix, removal of organs and closing the abdomen.
The results showed that phase 2 was the most intense phase of surgical stress, regardless of which premedication the dogs received.
When acepromazine and medetomidine were compared the results showed that within phase 3, all dogs that were given medetomidine had higher blood pressure compared to dogs that were given acepromazine.
The dogs that were given acepromazine had higher heart rate than the dogs that were given medetomidine in phase 0, phase 2 and phase 3.

Sangvinolent berättande : En studie av Yu Huas roman En handelsman i blod
The present MA thesis analyzes how body and blood functions as historical and narrative elements in Yu Hua's novel Chronicle of a Blood Merchant (1995). In the novel, the story and the plot can not be regarded as disparate items; the two levels of the text are tightly interwoven by what the thesis introduces as a sangvinolent narration. The term conceptualizes the use of blood as a structural element and the thrust of the text, in this case how the ability to sell blood is a prerequisite for the story and the plot.Close readings reveal the structural correlations between the blood-selling main-character Xu Sanguan in the plot on the one hand, and in the story on the other, which can be detected to have, inter alia, an effect on the temporality of the narrative. Themes linked to identity, belonging and survival (performativity, mimicry, reification and alienation) permeate the text. In the novel the body and bodily fluids are sacrificed in order to form and enforce perceptions of identity and societal roles.The rhetorical use of ?blood and tears? (Ch.
