Foraging and anti-predation behavior of Thomson?s gazelles (Gazella thomsoni) and Grant?s gazelles (Gazella granti) at a waterhole
Prey species make behavioral decisions to reduce the perceived risk of predation and the time spent vulnerable to predation. Behavioral responses to predators are for example selection of specific habitat types and the presence of predators influence individual vigilance. Furthermore, there is a variation in feeding niches with different herbivores focusing their foraging effort on different vegetation types which is also expected to affect the choice of habitat. Behavioral data on anti-predation and foraging behavior at on waterhole is collected from Thomson?s and Grant?s gazelles at Ol Pejeta Conservancy (0°00?N, 36°56?E) located in semiarid bushed grassland in Laikipia district of central Kenya.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Leverantörsrelationers betydelse : en fallstudie på Scania och två av dess underleverantörer
One of the most distinguishing features for companies today is that they must have a close collaboration and keep up a good relationship with their suppliers. This is important for the companies chance of survival and for them to compete in their markets. This essay will discuss the subject of Scania?s long-term collaboration with their suppliers. The purpose of the essay in this case study is to analyze if a long-term cooperation with a supplier is of essence upon renegotiations of continued collaboration.
Doing well by doing good : Hur kommunikation och anpassning av CSR skapar värde
Background: Today, It?s not uncommon that international companies and organizations have a higher turnover than the GDP of developing countries. Consequently, this may suggest that the choices companies make in the context of their business has a great potential to influence the world from an economic, but also from a social and environmental standpoint. From this the notion emerged that companies have a responsibility, referred to as Corporate Social Responsibility (CSR). A clear definition of the CSR concept is difficult to find, more than 37 different definitions has been identified.
Röstgivande romer : En komparativ analys av Katarina Taikons Zigenerska Hans Caldaras I betraktarens ögon
The Roma people have many times, and for a long period of time been described in a negative way, as a group of people unlike every other. Both novels and encyclopedias has been a part of this misleading discourse and therefore contributed to large misunderstandings. Also scholarly research from Sweden, and elsewhere, has featured inaccurate representations of the Roma people and altogether this has created negative attitudes towards Roma people which are still today a considerable problem.However, the last few years positive changes has taken place and today the Roma people is an official minority group in Sweden which, among other things, has led to promising possibilities, especially in schools, for a deeper understanding of the Roma people in the future. Reading Roma literature I believe is an important part of this.Katarina Taikon and Hans Caldaras both consider themselves Roma. They also have in common that they want to give voice for the group of Roma that has lived in Sweden since mid-nineteenth century.
INVERKAN AV HAVSF?RSURNING P? PROTONERBARA ORGANISKA F?RORENINGARAS EKOTOXICITET
Resulting from anthropogenic carbon dioxide emissions, average surface seawater pH is estimated to decline from today's approximately 8.05 to between 7.78 and 8.03 towards 2100. For ionisable organic pollutants, changes in pH can lead to a change in the degree of ionisation, which could influence the ecotoxicity of a compound by altering its bioavailability. In this study, potential changes in ecotoxicity of ionisable organic compounds resulting from ocean acidification are examined. This is achieved partly by conducting a literature review, analysing existing literature that investigates this relationship. Potential changes are also evaluated by examining marine ecotoxicity data for ionisable organic compounds on the watch list pursuant to Directive 2008/105/EC of the European Parliament and of the Council, as well as on the list of priority substances according to the 2022 proposal for amending the Water Framework Directive (2000/60/EC).
Hälsorelaterad psykosocial situation bland kvinnor från olika kulturer efter bröstcancer
The most common form of female cancer in Sweden is breast cancer and the primary choice of treatment is surgery. Removing a woman's breasts is not just removing a body part but is also strongly linked to the emotional life. This has psychosocial consequences and the reactions will be different depending on how people perceive health and illness. Factors that matter are both personal experiences and cultural factors such as religion, family, and the own standards and values. It is important that a nurse is aware of cultural factors that may influence the perception of care.
Mortalitet av bok i Biskopstorp och Frodeparken naturreservat, Halland :
The aim with this study was to investigate mortality in older respectively younger beech
stands (Fagus sylvatica), the different types of dead wood in the forest and the availability of coarse woody debris (CWD). The research was carried out in previously managed and seminatural stands in Biskopstorp and Frodeparken, located north of Halinstad in Halland,Sweden. Data were collected from 22 stands with at least 50 % beech and with a minimum age of 5 1 years, ranging in size from 0,67 to 19,9 ha. A transect was placed in each stand, in which the diaineter on both dead and living trees with a minimum diameter of 50 mm was recorded. On seven to 13 dead trees, depending on the size of each stand, decomposition stage, primary and secondary cause of death, amount of fungi and the type of the dead wood was noted.
Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift
Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.
Barn, ungdomar och genusperspektiv: Magisteruppsatsers utgångspunkter och problemval
A quantitative and qualitative study of all LIS Master theses applying a gender perspective on children-centred issues previously published at the Swedish School of Library and Information Studies. Two hypotheses were investigated: 1) studies with explicit gender perspective express strongest urgency; 2) study results confirm predeclared assumptions. A content analysis of all theses, and closer thematic analysis of ten, form the main question: Is there a risk that the theses? similarities in terms of urgency and confirmation create predictable conclusions? The theses? motivations behind the choices of research problems are explored in the content analysis. Two categories of motivation can be identified: 1) personal; 2) generally applicable.
Resurssnåla materialflöden - En fallstudie på Volvo Powertrain
From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.
Francisella tularensis subspecies holarctica : the curious case of a water- and mosquito associated bacterium in Sweden
Francisella tularensis, the causative agent of the zoonotic disease tularaemia, is highly contagious and potentially fatal for a wide range of wildlife species of the northern
hemisphere, also humans. Although recognized as a pathogen for over 100 years, much still remains to be elucidated concerning the ecology and transmission of the bacterium, hence this literature overview aims at compiling data regarding the aquatic association and the role of
mosquitoes in transmission of Francisella tularensis subspecies holartica, the sole subspecies in Sweden. While a linkage between the bacterium and natural waters stands beyond dispute, there is no consensus in the literature concerning its potential as a reservoir. However, two
prevailing theories can be distinguished; one proposes the water association being mammaldependent and thus merely the result of contamination from semi-aquatic mammals living in
close vicinity to the water source. The other, quite contrary, suggests mammal-independence and hence that water, possibly in association with protozoa, serves as an environmental reservoir for the bacterium.
En ny modell för att stärka kommunikation och samverkan mellan universitet och näringsliv
As a result of today`s competitive situation, the demand on the rapid development of research has increased. Both universities and companies are realizing the importance of a functioning and well-developed cooperation. A close collaboration and communication between universities and the business community has in many studies been shown to be very important for business development and knowledge transfer. The purose was to examine how communication and collaboration between universities and industry can be developed and strenghthen on the basis of innovative thinking. In order to initially identify the perceived problems the authors studied how communication and cooperation manifests itslelf today between the two parties, what does not work and how the existing tools for communication and collaboration look like today.
Den Jordiske Fadern. Bilden av Josef i barndomsberättelserna i Matteus och Lukas
The purpose of this study is to investigate how the authors of Matthew and Luke describe Joseph; The main aim is to see how the picture of him is drawn in the infancy narratives of their respectiveGospels; what unites, and what distinguishes the pictures of the two evangelists' account of Joseph,as a character and as a father.With the help of both textual and grammatical criticism, this study investigates - pericope bypericope - different aspects of Joseph's participation in the infancy narratives of Matthew and Luke; his relationship to the child and the mother, the terms used to describe him, and his overall modusoperandi. This essay builds its structure upon the individual study of each pericope, with the aim of painting a general and summarized picture.From the outset of already formulated uniting characteristics of the two gospels, as stated in Raymond E Brown's The Birth of the Messiah this study proposes that more can be said about the common features of Matthew and Luke, especially concerning Joseph's both character and relationto the child. First, this study suggests that both Matthew and Luke describe Joseph as the legal father of Jesus; second, both evangelists seems to describe Joseph as observant of Jewish law andcustom.The main impression of the two evangelists' birth narratives is however the differencesconcerning the description of Joseph. This study shows that there is one major common feature: the ambivalence evident in the evangelists' way of describing Joseph. On the one hand, both Matthew and Luke prescribe Joseph some importance; Matthew by describing Joseph and letting him act,Luke by calling him father and parent.
Hur livshistoriekaraktärer hos Europeisk abborre (Perca fluviatilis L.) påverkas av cykliska förändringar i populationsstrukturen
This report deals with life-history variation for Eurasian perch (Perca fluviatilis L.), with special emphasis on age and size at maturity in females, in perch populations that have changed in size distribution. The collection of fish samples was made with multimesh gill nets year 2011. The perch?s length, height, weight, status of gonads has been analyzed, and by observing the opercular bone the age has been determined. In two lakes close to Umeå in northern Sweden, Fisksjön and Ängersjön, the live-history traits of perch have been studied.
