Hur anpassar sig Gyps-gamar (Gyps rueppellii och G. africanus) i Östafrika till oregelbunden och osäker födotillgång?
In East Africa live two species of Griffon Vultures; Rüppel?s Griffon Vulture (Gyps rueppellii) and African White-backed Griffon Vulture (G. africanus). One of the apparently most important factors limiting the population of these birds is food supply. Griffon vultures nest for eight months of the year, and are during this period geographically tied down to the nesting place.
Svenska preferensaktier: Ett eget kapital- eller skuldinstrument?
On Nasdaq OMX Nordic Stockholm there has been a large increase in issues of preferred stocks since the financial crisis 2008. Aiming to explain whether preferred stocks have most of their characteristics relating to debt or equity, we answer four sub questions. Do all preferred stocks share the same features, or do they differ from each other? Our population is similar in characteristics, except for the preferred stock of Swedbank which is convertible and deviates when it comes to participation in dividends - instead of convertible the others are limited and redeemable. Further, the second sub question treats preferred stock in relation to the common stock quantitatively, in market data.
The influence of forestry stands treatments on brown bears (Ursus arctos) habitat selection in Sweden ? an option for Alberta forestry?
The brown bear population in Alberta, Canada has been decreasing, while the Swedish has been increasing and all the affecting parameters are not known. This study examined the difference in these populations to see if an explanation could be found in differences between the forest management. The aim of the paper was to see if stand treatments had an influence of brown bears habitat selection in autumn in Sweden and how the results can be used in Alberta. This was done by analyzing bear positions in Sweden with forest data, and comparing forest management data for the study area in Sweden with forest management data for Alberta. The results displayed that mature forests over 60 years that have been commercially thinned are selected by bears rather than forests over 60 years that have not been commercially thinned in.
Undernäring hos äldre personer med fokus på könsskillnader- En kvantitativ studie
Introduction: Malnutrition leads to loss of health and coexists with disease and loss of function. A good nutritional status becomes more important the older you get to maintain a good health. Studies show that it is important to identify and prevent malnutrition in its early stages. Men and women recieve different medical treatment in a number of different medical diseases. There are few studies in nursing from av gender perspective.Aim: The aim of this study is to examine the prevalence of malnutrition in the elderly in Västra Götaland with focus on gender differences when it comes to prevalence and nursing interventionsMethod: A register study with av quantitative approach is conducted to answer the aim.

Prevalensskillnad av katarakt mellan män och kvinnor i en synhjälpsökande population i Guatemala
Syftet med studien var att med hjälp av direkt oftalmoskopi undersöka om det finns någon skillnad i prevalens av katarakt mellan män och kvinnor i en population i Guatemala som sökt synhjälp. Metod: Studien genomfördes på patienter som sökt synhjälp via organisation Vision For All i Guatemala. Synskärpa och bästa korrektion utvärderades med hjälp av Snellen E-hake tavla på fem meter och provbåge och provglas. Både höger och vänster öga undersöktes med direkt oftalmoskopi på 30 cm avstånd ca 20 grader temporalt. Undersökningen utfördes odilaterat och graderades efter Mehra och Minassians studie från 1988. Totalt deltog 181 patienter varav 108 var kvinnor och 73 var män.
Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Värdepapperisering av samhällsfastigheters hyresflöden : En attraktiv finansierings- och investeringsmöjlighet för att bygga vård- och äldreboenden till en åldrande befolkning?
The number of elderly people has been steadily rising in Sweden for a long time and as a proportion of the population, the increase has been even greater. The population structure in the country means that in the not too distant future, there will be a sharp rise in demand for care and elderly accommodation.A tighter credit market as a consequence of new rules and regulations with a stricter capital and liquidity requirements combined with market turbulence, has made financing property developement more difficult and more expensive which has resulted in many companies using alternative sources of finance.DEmand for safe investments with low risk is high as the market is volatile and banks, pension funds, fund management and life insurance companies are looking for investments outside the stock market that can deliver a safe return in the longer term. There has also been a debate about whether institutional investors as the AP pension funds really should own properties directly.As properties for care and elderly accommodation are definable assets with predictable payment flows, long leases and often a local authority as tenant that would not risk cancelling payments, these would be highly appropriate for securitisation, i.e. to issue bonds or other tradable securities based on the cash flows from the assets.In other words, the securitisation of rent flows would offer the opportunity to create an attractive investment product of the type being demanded, well suited to institutional investor requirements, while at the same time, it can provide an attractive financing opportunity to meet the need for more care and elderly accommodation..
BarnABC
This project is a learning CD-ROM production aimed at first-time parents. It is using both sound and images, moving as well as non-moving. The purpose of the production is to be an interesting alternative to traditional books. We have been looking at similar productions like drivers license educational CD-ROMs and encyclopedias for inspiration and ideas on how to proceed. In order to give the content some dynamics, we've also added the element of 3D-animated sequences.
Havsöringens (Salmo trutta) och laxens (Salmo salar) lekområden och lekvandring i Vindelälven och Piteälven :
The population of seatrout and salmon are threatened by over-fishing in the sea
and loss of spawning and growing habitats caused by logging activities in many swedish
rivers. The knowledge of the spawning migration and the habitat use of the seatrouts
and salmon are limited. This study analyse the upstream spawning migration of Atlantic
salmon and sea-running brown trouts from the lower part of the rivers to their spawning
sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of
spawning sites in the rivers will help these fish population in future restoration programs.
In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20
salmon radio tagged and subsequently released and followed during their spawning
migration upstream Vindelälven. They were tracked on their position in the river once a
week.
Sverige 2112 : Ett narrativ om hur arkitekturen kan utvecklas om världen går igenom stora förändringar på grund av klimatförändringarna. En linjär och vertikal stad.
Om världen till följd av klimatförändringarna blir mycket varmare kommer förutsättningarna för hur vi planerar städer, infrastruktur och jordbruk helt att vändas upp och ner. De delar av världen som idag står för världens livsmedelsproduktion kommer vid bara några graders förändring bli obrukbara som betes och odlingsmark. Dessa förändringar kan komma att starta konflikter, och stora flyktingströmmar som tillsammans med förändrade klimatzoner helt kommer att rita om världskartan. i Skandinavien är det då troligt att vi behöver bygga samhällen och städer för miljontals nya immigranter, och detta samtidigt som vi befinner oss mitt i den mest fruktbara jordbruksmarken i världen. Om hundra år måste vi dessutom, oavsett detta, dubbla livsmedelsproduktionen globalt sett.Vårt samhälle blir allt mer rörligt och infrastrukturen utvecklas i allt snabbare takt.
Whispers in the forest : a field study about communication within Vi-agroforestry
The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data.
I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003)
Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.
Faktorer som bidrar till respektive hindrar nytta vid elektronisk journalföring
This study was carried out in the purpose of investigating the factors in the electronicmedical records system in Procapita that contributes to utility for the users and the factorsthat prevents the experience of utility for the users. The study was done within KalmarCounty and its employees within the field elderly care. The problem that we brought upwas that the elderly part of the population is growing quite rapidly whilst the gap betweensupply and demand on nurses and physiotherapists is increasing. This creates a problem ofits own in regards to how we are going to care for the elderly when there?s not enoughstaff for it.
Ayatollah Khomeini : De rättslärdas styre
A large part of the Iranian population resented the west, in particular USA and Great Britain, during the Islamic revolution in Iran 1979. The people were also resenting the adverse effects of the trumped up frame made in Iran. The last shah of Iran, Mohammad Reza Pahlavi was detested by many in Iran for its west-oriented regime. The resentment among many Iranians is a consequence of the violations of e.g. the lack of political and civil rights, there were no existing legal security in the society, there were no economic distribution and the regime of Mohammad Reza Shah violated the human rights.The resolution from an Iranian perspective for riot is not new, during the last centuries the abomination against the despotic kings have been existing varyingly and big riots have been raised. The Islamic revolution in 1979 was new because the revolution added adverse effects of west, the population detested west and expressed it by protesting through demonstration. The significance of the revolution in 1979 was also attributable to Islam.
