Reproductive physiology of the female cat

The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

Individers erfarenheter av hur migrän påverkar det dagliga livet : En litteraturöversikt

BackgroundMigraine is a comprehensive endemic disease who is affecting both women and men, but with higher prevalence among women because of hormonal factors. Risk factors for the disease are female gender, hereditariness, depression and socio-economic factors. Migraine can be triggered by factors like stress, menstruation, irregular routines for sleep and unbalanced meals and diet. Migraine is a condition that causes a big suffering for the affected individuals.AimThe aim of this study was to describe individuals' experiences of how migraine is affecting the daily life, out of the aspects like working life, family life and social life.MethodA literature overview was maintained, and eight qualitative studies and two quantitative studies between the years 2003- 2014 were analyzed.ResultsThe analysis of the articles lead to one main theme; "Guilt, compensating and restrictions" and seven subthemes "Not being able to perform their best", "Met with incomprehension", "Not being able to take care of home and children", "Not enough", "Avoiding activities", "Always be prepared" and "Living with restrictions".ConclusionMigraine is affecting the daily life among these individuals in a great extent. The disease makes it hard to perform well at work.

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Prevalence of selected infectious diseases in Samoan dogs

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

HTML-ramverk i praktiken : En studie av HTML-ramverk från utvecklarens perspektiv

This paper aim to present a model for evaluating what we choose to call HTML-frameworks, a framework that contains a set of CSS layouts and occasionally JavaScript support, based on the characteristics of the software quality standard ISO/IEC 9126-1. The methods used to produce this model is based on a field study that involved making a web portal with the help of a HTML-framework, some relevant literature and an analysis of the framework based on the characteristics of the ISO/IEC 9126-1 standard. The result was a model based on twelve different characteristics; functionality, web browser compatibility, collaborative skills, user-friendliness, documentation, visuals, graphic layout, performance, activity, professional support, replaceability and license. This model should be viewed upon as a suggestion to what a model for choosing HTML-framework could look like, because we haven?t had the time to test it in a real situation, so further studies are needed, and we believe there could be improvements made in the objectivity of the assessments of the characteristics..

Jämförande LCA av engångssängkläder och tvättbara sängkläder i sjukvården

Inom sjukvården används ? precis som överallt där människor sover ? sängkläder av hygienskäl. Problem med smittspridningar av typen multiresistenta bakterier (MRSA) och spridning av andra sjukdomar har drivit företag som Cellcomb i Karlstad AB till att utveckla engångssängkläder för att förhindra detta. Engångssängkläderna är skyddade av en biofilm som ska ge ökat skydd mot bakterier och fungerar som en barriär så att inte vätska tränger igenom. Problemet är att det inte finns mycket till underlag för hur engångssängkläderna står sig mot vanliga sängkläder ur miljösynpunkt.

Utveckling av en diameterklassmodell för grandominerade bestånd i Sverige :

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

Meningen med livet : hur 15-åringar i en stor och en liten stad i Sverige ser på livskvalitet

There are many good reasons to ponder about what it is that makes life worth living. To observe and reflect on what it is that gives a person a good quality of life is arguably the essential core of social-work. The aim of this research was to investigate how 15-year old youths interpret quality of life. The key areas that we explored in order to meet the research aims were: what did the youths interpret as a good quality of life for a 15-year old and for an adult, how did they view their own quality of life, and did they think that the regional context (i.e. if one lives in a big city or in a small town) affects how one interpret quality of life.The studywas based on interviews with four boys and four girls.

Solvärme på Utö

The guest harbor on Utö, Utö Gästhamn, is currently using electricity for heating all of the water used in the showers and taps. Because of the large amount of visitors, especially during the summer months, the hot water usage gets very high and that is also the case for the electrical bills. During the year of 2011 the cost of electricity for Utö Gästhamn reached a total of 257 500 kr. Out of these 257 500 kr approximately 142 000 kr, 55 % of the total cost, were because of the water heating.The report is the result of a cooperation with Skärgårdsstiftelsen, the Green Islands-project and Utö Gästhamn where the mutual goal is to dimension a solar energy system, to promote the sustainable development.Initially the different techniques for the solar energy system are researched. The techniques are plane solar collectors, evacuated tube collectors, pool collectors and photovoltaic cells.

Betjäningskostnader i olika distributionskanaler: En fallstudie av ett svenskt bokförlag

In a time of economic turmoil and financial crisis profitability matters rise higher and higher on company agendas. Many companies are pressured to find profitability to avoid layoffs or even bankruptcy. Profitability essentially depends on the margin on the product or service sold and the costs associated with selling these products or services and hence these areas are of vital importance if companies are to improve profitability. Previous research has focused, for the most part, on product profitability while customer profitability has received less attention. This study is based on a case study of a Swedish publishing house and aims to investigate how the company?s Cost-to-Serve varies between its distribution channels.

Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

SCA Skogs arbetsmetoder för att fastställa nyttan av en väginvestering

The basis of road investments is to minimize the transportation cost. The forest industry wants roundwood to be available during the whole year. One way of determine which road to invest in is to do a cost/benefit calculation. SCA Forest lacks a uniform approach to determine the utility of a road investment. The goal of this report is to describe how the organization works today and find areas of improvement. The data collection was done through interviews.

Ombyggnad av ventilation i kulturbyggnader

I detta arbete studeras hur en systemombyggnad i kulturbyggnader kan gå till med avseende påinstallationerna. I Sverige finns det idag totalt ca 4,7 miljoner byggnader av vilka ca 235 000-280 000bör genomgå kulturbevarande byggnadsvårdsinsatser. Vid ombyggnad av ventilationen i enkulturbyggnad är det viktigt att man, samtidigt som man får en ändamålsenlig och energisnål lösning,tar hänsyn till byggnadens karaktär och förutsättningar så att den kulturhistoriskt värdefulla miljönbevaras.I detta arbete studeras tre olika kulturhistoriskt värdefulla byggnader som genomgått renovering avventilationssystemet under de senaste tio åren. Byggnaderna är Skridskopaviljongen, Dekanhusetoch Södra Bancohuset, som alla förvaltas av Statens fastighetsverk (SFV). Efter samtal, studier ochundersökningar om de tre byggnaderna visar det sig att det är viktigt att i början av ensystemombyggnad i en kulturbyggnad, först läsa in sig på byggnaden samt ställa sig frågorna: vad skabyggnaden användas till, vilken verksamhet passar här, vilket systemval kommer att passa brukarenbäst mm.
