The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

Det är sedan länge känt att sömn på sjukhus är ett viktigt grundläggande behov för tillfrisknad. Det finns en bristande uppmärksamhet från sjukvårdpersonal om sömnproblematiken som finns på sjukhus, och miljöfaktorer som kan påverka patienters sömn negativt. Dessa faktorer kan förbättras om problemen identifieras och åtgärder vidtas för att förbättra sömnmiljön. Syftet med studien var att belysa miljöfaktorer som kan påverka patienters sömn på sjukhus. Studien är genomförd som en litteraturstudie där 21 vetenskapliga artiklar samlades in och granskades.

Background: Patients with cancer of the lung have to endure a quantity of physical, psychological and social difficulties. In their exposed position they are in need of help and support to pull through the situation. With the knowledge of factors effecting lung cancer patients? quality of life, it will be easier to give the help and support they need. Aim: The aim of this study was to describe factors effecting lung cancer patients quality of life from the patient?s perspective.

Senare års forskning visar på att obstruktivt sömnapnésyndrom, OSAS, är en både underdiagnostiserad och underbehandlad sjukdom. Detta beror delvis på att många personer med OSAS är omedvetna om sitt tillstånd. Sjukdomen innebär återkommande totala andningsuppehåll under sömn och en hypoxi som leder till en rad olika komplikationer, däribland hjärtkärlsjukdomar. Syftet med denna studie var att utreda vad som påverkar OSAS och vilken roll sjuksköterskan kan spela i vården av dessa patienter. Metoden som användes var en litteraturundersökning.

The main focus of this study was to investigate how Swedish military veterans experience that events during an international service affect them after completed mission. This also includes the contact with their relatives. Secondly, this study deals with the course of the crisis, personal defense mechanisms, cumulative stress and post-traumatic stress syndrome (PTSD).The study was performed using a qualitative method and comprises individual interviews with six Swedish veterans. The responders were all men of different military positions, who participated in one or more international missions during 1993 to 2011.The results of this study show that, according to the veterans, the return back home is the most strenuous part of an international mission. With all the new experiences that an international service brings fresh in their memories, it is hard to re-adjust to the life of a civilian.In connection with the return back home, different degrees of stress reactions were also commonly seen, for example sleep disturbance, restlessness and exhaustion.

To differentiate between bones from sheep (Ovis aries) and bones from of goats (Capra hircus) is a long lasting challenge for zoologists, archaeozoologists and osteologists. Especially considering archaeological remains which are often found fractured and poorly preserved due to taphonomic processes. Zeder & Pilaar?s (2010) and Zeder & Lapham?s (2010) methods of species differentiation has shown promising results when used on bones from modern sheeps and goats. This paper aims to evaluate these methods by exerting them on excavated bones from kv.

As a pet owner you are likely to someday face the decision to euthanize your pet and as a veterinarian or veterinary technician you are the one to perform this euthanasia. The reason for euthanasia may be depending on the animal, for instance illness, age and behavioral problems or depending on the needs of the owner or the society, so called convenience euthanasia. Many different euthanasia methods can be used when putting an animal to sleep. The method preferred in animal hospitals is pharmacological euthanasia either by inhalation of anesthetics or by injection of a euthanasia agent. If the pet owner wishes to be present during the procedure it is important to prepare him for what will happen. Many animals are sedated before the euthanasia in order to reduce anxiety and to ensure a softer transition between life and death. The euthanasia agent can then be administrated for instance intravenously or intraperitonealy.

Syfte. Syftet med studien var att beskriva sjuksköterskans erfarenhet av att befrämja patienters sömn ur ett omvårdnadsperspektiv.Bakgrund. Sömn är ett tillstånd som befinner sig utanför den medvetna kontrollen och ses som en viktig del av livet. Människan vet av erfarenhet att sömnen är ett stort behov och utan sömn en längre tid förändras våra beteenden, vår förmåga att koncentrera oss minskar, temperamentet ändrar sig och handlingsförmågan avtar. Tidigare forskning har visat att patienter inneliggande på sjukhus ofta klagar på sömnstörningar.Metod.

Confusion can be a life threatening condition that is often missed by the nurses, thus it occurs in the same range as pain, fever or infections. Aim: The aim of this study was to describe the phenomenon of confusion among elderly patients, in order to establish a wider understanding of the patient's nursing needs. Method: Literature study based on scientific material. Results: The result showed the patient's ability to recollect and reconstruct episodes of confusion. During the confusion the stories contained a wide variety of experiences, such as threat, fear, suspicion, chaos and order, unreal experiences, a need to escape and a bad sleep.

The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.

This essay is a time-geographic study of workinglife mobilities and investigates two days of work for five respondents. One from home and the other from the persons workingplace. Qualitative and quantitative methods has been applied to illustrate and analyze the two days along with time-geographic constraints. The findings are concluded into themes which represent the two local pockets of order: Home and Workplace. Themes of home are: Comfort station, Household, Curtained-off, Tele-contact and Environment.

Choir singing is one of the most popular national movements in Sweden but the knowledge of the meaning of this activity for health and well being from the choir singers? own experiences is limited. The purpose of this study was therefore to develop useful knowledge about the meaning of choir singing for participating persons from a health perspective. The data was collected through qualitative interviews with six different choir singers and went after that through a comprehensive analysis which resulted in four main categories: an oasis in the existence; possibilities of meetings and solidarity; goals and musical development; and physical and emotional well-being. The results showed that the choir activity represents a place where the singers can escape the demands and the stress factors of everyday life and where they get the opportunity of meaningful relations with other people.

Bakgrund: Tidigare präglades vården utifrån ett synsätt, där vårdgivaren styrde över vården. Detta synsätt har successivt övergått till att patienten bör vara mer delaktig och fatta egna beslut. Information påverkar även graden av delaktighet och förmågan att fatta beslut självständigt. Patientens delaktighet i vården styrks i patientlagen och sjuksköterskan har ett ansvar att bjuda in patienten till delaktighet. Syftet: Att beskriva patientens upplevelser av delaktighet i vården.
