Dynamic obstructions of the equine upper respiratory tract
Dysfunction of the upper respiratory tract is a common cause of impaired performance and intolerance to exercise in racehorses and include several upper airway obstructions. The ones termed dynamic obstructions are primarily seen during physical exertion and affected horses often appear to be normal during endoscope examination at rest. The correlation between diagnoses made at rest respectively exercise is low, suggesting that an examination at rest alone is likely to be insufficient.
The upper respiratory tract is exposed to great differences in pressure throughout the respiratory cycle; variations that are further altered during strenuous exercise and affect the rigidity of upper airway structures. In presence of great fluctuations in pressure, stability is achieved through coordinated and synchronous neuromuscular mechanisms. Due to nerve damage or anatomical abnormalities, these functions may be disrupted and further cause a dynamic collapse of the upper respiratory tract when pressure changes become too severe.
The etiology behind the neuromuscular dysfunction is not yet fully understood.

Intranät och dokumenthantering vid ett mindre till medelstort företag En fallstudie
The aim of this masters thesis is to learn how an organization has solved its information management via intranet and document management. The purpose is to identify what different types of information are made available via an intranet, how this information is structured and what functions the intranet includes. Conventions, directions and advice about intranets and document management were studied, with the purpose to compare whether the systems of the company correlate with these. Other issues considered in the thesis, are how the employees of the organization use the intranet and how the document management is organized. To get an understanding of these questions the structure and functions of the intranet were studied empirically and a questionnaire on what the employees need and use, concerning the intranet, was sent out to 130 employees.
Missuppfattningar inom genetiken: En litteraturstudie om hur missuppfattningar inom genetiken hos h?gstadie- och gymnasieelever kan motverkas
In schools, misconceptions about genetics can arise due to several factors, and the consequences of
these misunderstandings can be significant. Lack of education can play a central role in the spread of
misinformation about genetics. When teachers lack sufficient knowledge or do not have access to
up-to-date resources, they risk inadvertently conveying inaccuracies to students. Additionally, students
own preconceived notions and misinterpretations can be reinforced through interaction with their
peers, creating a vicious cycle of misinformation.
In this study, various misconceptions within genetics education have been identified and analyzed,
while different strategies to prevent these misconceptions have been examined. The study revealed that
the two most common misconceptions are the confusion between "genes" and "DNA" and the
simplified perception of genetic determinism.
Externa styrelseledamöter i ägarledda företag - vad externa styrelseledamöter kan bidra med och vilka de vanligaste svårigheterna för ägarna är
The work of the board in owner-managed firms often differ compared to the work of the board in large listed companies. Since the owners are working in different roles, the board in owner-managed firms might discuss topics outside the typical boards agenda, such as questions relating to ownership structure and operational matters. This thesis examines what external board members can contribute with in owner-managed firms, and which the most frequent difficulties are for the owners when deciding to recruit external board members. Through qualitative interviews, three owner-managed firms have been studied, which together with two expert interviews and five seminars, creates the empirics. In the analysis, the empirics are compared to what the earlier theory states.
Kan konsumentförtroende användas för att prognostisera konsumtion i Sverige?
Making accurate predictions of private consumption expenditures is a difficult task. This thesis examines if consumer confidence can be used to forecast consumption. Using regression analysis, the link between consumer confidence and private consumption expenditures is analyzed for Sweden between the years 1994 and 2005. Two different models are estimated. In the first model consumption is regressed only on consumer confidence, while model two is extended to contain more variables.

Utsläpp av växthusgaser under islossning i små boreala sjöar
Freshwater ecosystems have long been neglected as an important part of the global carbon cycle. However, research shows that most of the world?s lakes are net-heterotrophic and consequently emitters of greenhouse gases to the atmosphere. In many boreal and north-temperate lakes, most of the yearly emissions usually occur in spring, shortly after ice-thaw. The aim of this study was to quantify the flux of carbon dioxide (CO2) and methane (CH4) in three boreal lakes, during this annual event.
Det cykliska : The cyclic
In this essay I analyze the way my collection of poetry relates to the concept cyclic. What is cyclic and what different interpretations are there concerning the concept? Which other related concepts are there regarding things that seem to reoccur regularly? How does the cyclical, the circular, relate to the linear in regard, for example, to the perception of time? Life often creates the sense that different phenomena and experiences repeat themselves. Different processes are conducted according to regular or irregular cyclical phases, situations seem familiar and events can be relived. Starting from my writing project Sinnligt kviller, a collection of poems, I discuss these questions in themselves and the impact they have had on my collection. I describe the phenomenon cyclic as a result of the emotions and moods this term creates in a more or less decisive way. The intention with this paper is to show how Sinnligt kviller offers different perspectives of and reflections upon the various feelings provoked by the cyclic in our lives, feelings that are given my own voice in the literary text under study..
Barns tankar om älven : Förskolebarns förståelse av älven och vattnets miljö
AbstractThis research is about pre-school children?s conceptions of the river and the water environment. The aim of this study was to apply a new teaching method based on the outside learning, as well as to test the method and see if it works, i.e. if children get more knowledge this way compared to ordinary methods like teaching in the class-room which involves showing pictures and discussion of them.The main questions in this study were how children get new knowledge through outside learning and how effective this learning method is, i.e. how much they noticed and learned about the river and the water environment as a result of that outside observation.
CORRELATION BETWEEN ENDOMETRIAL MARKERS AND PREGNANCYOUTCOME IN WOMEN WITH UNEXPLAINED INFERTILITY
ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

Sol, jord och vatten. : Barns tankar om den ekologiska processen
Studies show that the interest and knowledge about science among teenagers is decreasing. They also reveal the difficulties to explain the ecological processes and that the ideas about the nature are collected from everyday life and early school years.The intention of this investigation was to find out more about children?s ideas and knowledge about the ecological processes and to compare these results with the curriculum.The method was a questionnaire and interviews with children in school year 1 ? 6. The aim of the studies was also to find out if any progress connected to age could be found, concerning understanding of the ecological processes.The results showed difficulties in achieving the predestined goals for biology and chemistry concerning ecology cycles and they differed a lot between the children. Often the learning process showed very little progress.
