FN:s barnkonvention : Demokratins positiva inverkan på staters implementering av barnkonventionen. Fallet Nigeria.
Even though many states have ratified the UN Convention on the Rights of the Child and sworn to protect human rights, viloations occur every day both in developed and developing countries. United Nations gave Sweden critique for not implementing the Convention conrerning article 11, which raises the question how respected the Convention is amongst other states? Does democracy contribute to a Higher level of implementation?.
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten
Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.
Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds
Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens. The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.
Skapandet av morgondagens lärare : En komparativ analys av två lärarutbildningars introduktionskurser
This study intends to analyze and compare the core litterature outlined in two specially selected teacher training establishments. The purpose of the investigation is to examine what specific perspectives they focus upon and the competences they require for teachers of tomorrow.The result shows that there are certain differences in perspective when varying the point of focus, but there are also common elements inte the core litterature between the two establishments. This analysis will provide a base for discussion on how the differences may be a result of the environment where the colleges of Higher learning are situated and also on the individual needs in the surrounding area when they were first established..
Betygsskillnader på Kallingeskolan : - ett attitydsproblem?
It?s not a new occurrence that girls have Higher grades than boys. Statistics show the same at the Kallinge school in Ronneby. There is a great difference between boys and girls in their grades from the ninth class. There are many different factors that affect the pupils.
Perceptuell och akustisk bedo?mning av ro?stfunktion hos barn med tonsillhypertrofi : Effekter av kirurgi
In Sweden over 10.000 patients annually, mostly children, undergo tonsillar surgery. The most common surgical method is total removal of the tonsil, tonsillectomy (TE). During the last decade partial tonsil resection, tonsillotomy (TT), has been reintroduced and is associated with lower primary morbidity and less postoperative pain. The aim of the present study was to evaluate if and to what extent 4-5 year old children?s voice function are affected by tonsillar hypertrophy compared to controls and to study the effects of the two surgical techniques on vocal function.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations Higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Optimalt mottagningsstall för kalvar : en fältstudie
A cattle producer that buys calves that are younger than six months to the herd should have a starter stable to prevent infection spreading in the herd. According to the Swedish animal welfare regulation there has to be a starter stable if more than 50 calves that are younger than four months are bought in yearly to the herd. The aim of the study was to improve the knowledge about bovine buildings and management of starter stables to obtain optimal weight gain and health of the calves. The hypothesis 1) The younger the calves are when purchased, the Higher the calf mortality and 2) Purchasing calves from a high number of herds involves a Higher risk of calf health problems and calf mortality were tested in the study. The objective of the study was to give advices by way of presenting ideal solutions of how a starter stable should be constructed and managed.
A field study was done during June to September 2008 to collect knowledge and experience from existing starter stables.
Wavelettransform med Morletwavelets för analys av satellitmätdata
This thesis is divided into two parts. Part one contains a general description of the flexographic printingtechnique. Part two contains a more detailed investigation in the areas substrate, inktransfer and trends, which are only briefly commented in part one, and conclusions and comments.The major problem concerning substrate is washboard. This phenomena can be limited if one can control and minimize the amount of glue applied in the single- and double facer, use high surface weight on liner, use low surfaceweight on fluting and control the humidity during the conditioning of the corrugated board. Corrugated board with a smooth surface radically increases the quality in print.

Identifiering av fel i skogliga beståndsregister med hjälp av satellitdata :
This thesis has focused on the possibility to use a satellite image method developed by Metria Mijöanalys to identify stands that are wrongly registered in Holmen Skogs database. The method is only intended for identifying stand with poor descriptions in Holmen?s database that needs to be updated and not for updating the stand information.
The study area is located several km west of Hudiksvall on the borderline between Gävleborgs- och Västernorrlands län. The area is covered by a SPOT image from 2005. By which Metria Miljöanalys has made estimates of forest parameters for all stands in the area, and compared them with corresponding estimates according to the stand database.
Housing of ringtailed lemur, Lemur catta, from an ethological perspective
Sheep production is the only animal production in Sweden that is increasing. Therefore,increasing knowledge of the production is of great interest. In order to run a viable sheepproduction, producers needs to be successful in the breeding of the animals and achievean economic surplus in the end. Lambs that are born healthy and vital have greaterconditions to perform high lamb weight gains and thus a successful production. Thereare many factors affect the survival, birth weight and early weight gain of the new bornlamb.
Skogseldens påverkan på epifytiska trädlavar på tall i relation till brandintensiteten :
Not much is today known about how epiphytic lichens are effected by fire. A considerable part of the fires in Sweden today are prescribed fires for the purpose of environmental conservation. How these fires affect lichens is largely unknown. The aim of this study is to find out how epiphytic fruticose and foliose lichens on Scots pine are affected by fire, and to elucidate the relationship between fire intensity and the survival of lichens and later re-colonization.
The study was performed at three locations just outside Umeå in Västerbotten that were burned 5-7 years earlier. In all locations there were larger groups of surviving Scots pines with varying amount of fire-damage in the crown, which enabled a reconstruction of fire intensity.
