Towards an Understanding of Heterosexual Risk-Taking Behaviour Among Adolescents in Lusaka Zambia

This thesis investigates the underlying factors behind sexual risk-taking and non-risk-taking behavior with regard to Sexual Reproductive Health (SRH) among adolescents in Lusaka, Zambia. The Qualitative Approach was used for data collection and analysis and using the theory of Social Construction, the author explains how different contexts and aspects in the Zambian Society, that is Traditional, Socio-economic, Political, etc., influence the sexuality or sexual behavior of young people in Zambia. Hermeneutics was used to interpret the meanings in the texts/transcripts acquired through data collection and from the author?s knowledge and understanding of the Zambian historical and cultural contexts within which the participants of the research were constructed. Max Weber?s Ideal Type concept was also used to explain that each young individual?s sexual behavior is uniquely constructed by societal aspects.

Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

Färgval hos blomkrabbspindeln (Misumena vatia) med och utan konkurrens

The colour choice of spiders and the effects of competition on this phenomenon were examined in the laboratory using the sit-and-wait predator goldenrod crab spider (Misumena vatia, (Thomisidae)). This species can  be both white and yellow (could also change colour)  and it was here examined whether individuals preferred to sit on flowers which has the same colouration as their bodies. I found that M.vatia showed preference for flowers that matched their own body colour, but when competition was introduced this preference disappear. It seems, however, that position is a factor that can influences the substrate decisions of M. vatia, where the edge of the flower is preferred..

Impact of hygiene training on dairy cows in northeast India : en hygientränings påverkan på mjölkkor i nordöstra Indien

Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.

Tick burden in neonatal roe deer (Capreolus capreolus): the role of age, weight, hind foot length, and vegetation and habitat on bed sites

This thesis deal with tick burden on roe deer (Capreolus capreolus) fawns, in relation to age, weight, hind foot length, and as well as to vegetation and habitat on bed sites. Roe deer fawns (N = 25) were captured from May 27 to June 27. Samples of ticks were collected and tick burden were estimated. Of all sampled ticks the nymphs and adults were Ixodes ricinus, while the larvae were not identified. 4.4 % of the sampled ticks were larvae, 55.0 % nymphs, 26.8 % adult females, and 13.8 % adult males.

Hundens parvovirus : patologi och riskfaktorer

Canine parvovirus is associated with two disorders: enteritis, which is common, and myocarditis, which is rare. Prominent clinical signs of parvovirus enteritis are vomiting, diarrhea and rapid dehydration. Canine parvovirus type 2 (CPV-2) is very contagious. When CPV-2 first emerged it had high rates of mortality, but later studies have shown that most infections are self-limiting and do not require veterinary care. Mortality rates vary greatly, and therefore it is important to determine risk factors for developing severe canine parvovirus enteritis.

Mångbruksplan Äspinge 2:2

This plan of multiple-use is made on the private owned forestproperty Äspinge 2:2 in the middle of Skåne. The term ?multiple-use? came to Sweden in the beginning of the twentieth century and has slowly grown until about 30 years ago when the laws of nature conservation and sustainability was written into the forest law. The so called ecoturism got more and more popular and people began to seek space and silence in difference to the life in the highly populated areas. This also encouraged foreign tourists to come to Sweden. Mostly danish, german, and dutch people.

Moraliskt ansvar i privat konsumtion

The aim of this essay is to find out how students at Malmö University relate to moral responsibility in their private consumption. I am going to test moral theories in order to find out if researchers have a too moral starting point in comparison to everyday use. Through a critical research, free from valuation, I also aim to raise a discussion about moral responsibility which should lead to fair trade in the long run. My essay discusses the subject out of a Swedish city, Malmö - a place where many stores, cafés and restaurant are using moral responsibility as a step in their marketing. The results show that students are interested in morality but their financial conditions are their prior factor..

Uppfödares syn på inridningshästar i grupphållning : enkätundersökning

The horses? natural behaviour is easier to satisfy in a loose-housing system than housed in a traditional box. Law?s and science suggest that we should house horses in loose-housing, which improve the horse possibility to perform natural behaviours, to interact socially with other horses and to have more possibility to movement. It?s more timesaving in a working population aspect and a economic gain in materials. We noticed that it?s different opinions about what people in the horse society thinks about having youngsters housed in a loose-housing system.

Rådgivning angående profylaktisk kastrering av den friska tiken

Working as a veterinary nurse includes advising animal owners, helping them to make discisions through well-based facts and experience. Preemptive spaying of the healthy bitch brings many advantages and disadvantages. It leads to cessation of gonadal hormone production, and how the exact extent the surgery affects the dog is not yet fully understood. The sex hormones mainly control the reproductive system, but receptors of these hormones are found in many tissues of the body, and have complex relationships with other hormone systems. Spaying decreases the metabolism although the bitch gets an increased appetite, which enhance the risk of obesity, unless the owner restricts food intake.

Svampar associerade med raps : betydelse för uppkomst och grödetablering

Oilseed rape is an important crop in Sweden and is grown on about 90000 ha today. The interest in oil seed pro-duction is increasing because of growing demand and high prices for oil seed both in Sweden and Europe. However, an increased intensity in the oil seed production can bring higher risk of yield losses due to fungal diseases. The purpose of this study was to investigate what different fungi are associated with oilseed rape under field conditions and if their incidence is correlated to crop establishment problems. This study was carried out in three parts: 1) investigations on fungal community structure in roots and rhizosphere soils from young spring- and winter rape plants sampled in failed respectively good establishment patches in four fields, 2) investigations on the pathogenicity of fungi isolated from oilseed rape in controlled environment and 3) investigations on the effect of different fungicide seed treatments on germination and early plant development in a field soil naturally infested with damping off- and Verticillium wilt pathogens. The studies on community structure using a combined approach of standard fungal isolation techniques and DNA based methods revealed a high fungal diversity in three out of four studied fields of spring rape and winter rape. For some unknown reason, very few fungal species were identified from the fourth field.

Prevalence of antibodies for Peste des petits des ruminants virus and Brucella and related risk factors in goat herds in urban and peri-urban agriculture in Kampala, Uganda

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.

Centrumhandel i relation till externhandel : - en fallstudie om Strängnäs

In the 90's the establishment of external trade centers had a strong growth in Sweden, primarily in large and medium cities. Gradually took smaller towns by this development. In larger cities with larger and growing customer base than in small towns were not affected by the trade centers heavily, but in the smaller towns where the customer base was smaller, there was a risk that it created a negative competitive relationship between external trade center and trade in the citycenter. In some cases, competition is a positive development for both the citycenter and external trade areas, but in some cases there was a risk that the center became impoverished. In such situation there are theories that the different variety of different types of goods should be at the center and in external trade center could lead to a balanced trade relationship.

Utveckling av gran, Douglasgran, bok och tall under skärm av hybridlärk :

?Development of Norway spruce, Douglas fir beech and Scots pine with a larch shelter wood? is a report written by Per-Olof Magnusson. The thesis is a compulsory part of forest engineer program at ?Skogsmästarskolan?, SLU, Skinnskatteberg, Sweden. The purpose of this report is to describe and evaluate an experiment with hybrid larch (Larix x eurolepis) as shelter wood, and different tree species growth and survival depending on the density of the shelter wood. The experiment is conducted by southern Swedish forest research centre, faculty of forestry, SLU in Alnarp. The hybrid larch ought to be an interesting alternative to birch (Betula sp.) as shelterwood on suitable sites in southern Sweden.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.
