Biologisk mångfald i små grönområden : Inventering av insekter och fåglar i bebyggda områden i Solna kommun
All over the world the urbanisation increases at the expense of green areas. Many plants and animals are endangered today because their habitats gets smaller or disappear. The green areas that are left in city centres and suburbs are often small and surrounded by roads and buildings. Despite this, several studies have shown that these small green areas may house large biological diversity.This project aims to study the biological diversity in small green patches in residential areas. The study has been carried out in Råsunda in Solna municipality (Stockholm county) during the period May?July 2006.Three equivalent areas (5000?10 000 m2) with quite many old oaks were chosen for the study and inventoried for birds and saproxylic insects.

Tillståndsprövning - för lantbruk med djurhållning : en intervju undersökning med länsstyrelserna i Kalmar- och Hallands län.
The task of making a correct application for B- activities is the foundry time consuming
task. Information and facts concerning your entire business activity shall be attached into
a description of environmental consequences, which will be the basis for the decision
making whether the activities shall be granted a permission to practise environmentally
hazardous actions or not.
When the Environmental Act were established 1999, the permission process became
more extensor. With this study I want to give an insight about how these applications are
made. The methods I have used to collect information are a study literature where the
Environmental Act has been the focus, and qualitative interviews with two County
Administrative Board. I used the Environmental Act to understand why permission is
needed and the interviews to give me insight in how the work is done.
My conclusion is that it is very unusual that an application is granted without
complements.
En jämförelse av sitkagranens (Picea sitchensis) och den vanliga granens (P. abies) produktion :
Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the
West Coast of North America, from Alaska in the north to northern California in the south.
Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs
in single pure as well as in mixed stands.
The main purposes of this study were to describe the Sitka spruce growing characteristics and
the volume production in comparison to spruce (Picea abies). The possibility to predict future
volume production by using prognosis tools designed to be used on spruce were also studied.
The material that has been used in this study are permanent sitka trials established by the
Faculty of Forestry fixed Sitka trials and also material gathered in this study.
A literature study was also carried out in order to determine the Sitka spruce growing
characteristics.
Sitka spruce has a high adaptation and a high volume production on a broad scale of soil
types. The tree species is a pioneer species that has a fast early growth and in combination
with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the
single most limiting factor for where the Sitka spruce can be planted is frost. This factor can
be limited by using plant material with a well-suited provenance.
According to the literature, the Sitka spruce has an average total volume production that is
between 20-40% higher than spruce.
Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :
The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study.
The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.
Aktivitet, läggnings- och resningsbeteenden, tillväxt samt renlighet hos kvigor i liggbås respektive djupströbäddsbox :
The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter.
The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.
Salmonella prevalence in the poultry feed industry in Pakistan
Abstract
One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs.
Newly established poultry industries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.
Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser
Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.
Communication of CSR activities : a case study in the dairy sector
Recent corporate challenges require effective communication in order to secure a company?s reputation. Companies as a result, need to be committed to a series of corporate social and environmental practices along with their financial commitments to their shareholders and investors. In fact, businesses are required to go above their ordinary operations and involve all potential stakeholders that can be affected by their strategies. Companies also need to communicate social, environmental and economic consequences of their activities along with their CSR commitments to their internal and external stakeholders in order to make a better corporate image and improve their market opportunities.
Säker hantering av lösgående nötkreatur :
After I heard that two deadly accidents in farming 2003 were created by work with
cattle, I got the idea of writing this degree project. So far there are not too many reports
written about safety for the worker nor the animal. Therefore it will fit in with a report
about safe handling of free stalled cattle.
The Swedish Board of Agriculture would also like to do an information material about
outside stalled cattle with this degree project as a background.
The collecting of material was made by visiting farmers. The goal was to visit 15 ? 20
herds and when this is being written 19 herds have been visited.
Förekomst av salmonella spp hos katter i Sverige
Salmonella in cats has been documented for many years. Infection with S. Typhimurium,which is often referred to as Songbird fever, is believed to be caused by birds whoinadvertently infect cats. The disease is often seen during the springtime when songbirdsreturn from their winter habitats, while other birds who have stayed during the winter are intheir weakest condition of health. In the spring of 1999 an epidemic of S.
Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Vegetarisk kost - ett möjligt behandlingskomplement för symtomlindring vid reumatoid artrit?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: A vegetarian diet, a possible treatment complement for relief of symptoms ofrheumatoid arthritis? A systematic review.Author: Alexandra Ahlsén and Caroline ForsbergSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background: Rheumatoid arthritis (RA) is a chronic remitting polyarthritis that is relapsing.Symptoms are inflammation of the joints with pain, stiffness and degradation of joint tissue.In some cases, also other parts of the body are involved. The treatment consists ofmedications to reduce pain, inflammation and degradation of joint tissue. Today, the offerednutritional treatment is primarily focused on meeting energy requirements and nutrient needs.The diet has also been discussed as symptomatic treatment, and one of the factors believed toinfluence the symptoms is meat.Objective: To assess the evidence as to whether a vegetarian diet affects the symptoms ofrheumatoid arthritis, and if so, to suggest how it can be implemented in practical dieteticswork.Search strategy The databases used in the literature search was PubMed, Scopus, and AMED.The search words used were: "rheumatiod arthritis", "vegetarian", "vegan", "diet", "meat" and"animal protein".Selection criteria: Studies investigating a vegetarian diet on the symptoms of RA wereincluded. Only RCT, clinical trial, controlled clinical trial, human studies and original articlesin English or Swedish were included.
Bedövningskvalitet vid användande av bultpistol på nötkreatur
Djurvälfärd vid tidpunkten för slakt är en fråga som engagerar allmänheten. De flesta nötkreatur i Sverige bedövas med bultpistol inför slakt, med syftet att befrias från onödigt lidande. Undersökningar visar dock att bedövningskvaliteten i många fall inte är tillräckligt
hög efter skottet. Den här litteraturstudien syftar till att undersöka hur en god bedövningskvalitet säkrast kan uppnås vid bultbedövning, det vill säga vilka vapen, vilken
träffpunkt och vilken skjutkraft som har visat sig ge bäst resultat, samt hur situationen ser ut i dagsläget.
Tidigare studier har visat att mellan 8,7 och 31,8 procent av djuren inte uppnår en god bedövningskvalitet efter skottet och statistiken ser ännu sämre ut för tjurar och äldre djur.
Vilka indikatorer som används för att bedöma bedövningskvaliteten varierar lite mellan olika
slakterier men den vanligaste och förmodat säkraste indikatorn är att titta på djurets eventuella
kornealreflexer. Skottets träffpunkt finns reglerad i lagstiftningen men studier har visat att
även avvikelser från denna punkt kan ge en god bedövningskvalitet om vapnet som används
har tillräckligt hög kapacitet.
