Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato
Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant
growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth
interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined Literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant
bioelectromagnetics and its potential horticultural usability.

Fysisk aktivitet som fallprevention i särskilt boende - en litteraturstudie
Our population are ageing. As this happens more people will be in need of long
term care facilities. We now know that some elderly people with certain
background factors are more likely to be injured or sick. One of the four biggest
background factors is fall propensity. Most of the reported falls come from long
term care facilities, approximately 60 % of the care takers in long term care
facilities fall one time or more each year.
Patienters upplevelse av livskvalitet i livets slutskede inom den palliativa vården : en litteraturöversikt
Background: Palliative care is a type of care, which does not cure but eases the suffering caused by the disease. The goal of palliative care is not to extend or shorten the patient's life, but to relieve pain and distressing symptoms and to promote the patients? quality of life (QOL). QOL can be understood as a subjective sense of happiness of existence, which means that the patient is experiencing life when her total life situation is consistent with her ??wishes.

The Literature review was based on 12 scientific articles. The results of the study were divided into six categories; The nursing staff?s relation to the parents, Support group, ?Home-early program?, Decision-making, A work in progress and A safe and efficient method.
Sjuksköterskans förhållningssätt i vården till patienter som genomgår inducerad abort : En litteraturstudie
Theoretical framework: The Theory of Human Caring by Jean Watson was used as a theoretical framework.Aim: The aim of this Literature review was to describe the attitude of nursing patients who go through an induced abortion, from a nurse perspective.Method: This Literature review is based on a sample of nine qualitative and quantitative studies, collected in the databases Cinahl, PubMed and PsycInfo. The qualities of the studies were assessed through modified templates. Analysis of the results from the studies was inspired of a content analysis.Findings: The nurses experienced their work as meaningful since they give support to the patient. The nurses felt that their work was justified when the decision to have an abortion was well thought through and they felt respect towards the patient when they were aware of the patient?s circumstances.

Mjölkkors behov av att ligga och att sova
The aim of this Literature review was to investigate whether the modern dairy cow has the time she needs to lie down and to sleep and what deprivation of these behaviors could lead to. Current research seems to agree on the fact that sleep is essential but there is no uniform explanation of the function of sleep, even though there are many theories. It is known that sleep has an important impact on the immune system and that sleep is increased in case of an infection. Sleep deprivation causes many negative effects including reduced function off the immune defense, increased metabolic activity, malnutrition and increased heart rate. It has also been found that deprivation of sleep could cause increased mortality.
Ensilering i plansilo

There are many silage additives on the market, some of them are
presented including how they act in the ensilage process.

Hörselnedsättning hos barn och ungdomar till följd av platinabaserad kemoterapi - en beskrivande litteraturstudie
Success in treatment with platinum-based chemotherapy against different types of cancer tumors is limited by side-effects such as hearing loss which can have a large impact on the individual`s quality of life. It is of great importance to continue with studies that address this complex of problems.Objective: The aim of this Literature review is to investigate the impact of platinum-based chemotherapy on hearing in children and adolescents treated for different types of cancer.Method: A descriptive review of literature was made based on sources from 15 different studies on the impact of platinum-based chemotherapy on hearing in the target group.Results: The survey of the studies shows that platinum-based chemotherapy causes incidence of hearing loss by differing degree in the target group. Dosage of a platinum-based substance appeared to be the most significant factor. Treatment with both cisplatin and carboplatin was more ototoxic than treatment with only one of these. Greater risk for hearing loss was to a higher degree observed in younger children.
Crossbreeding in dairy cattle
The aim of this Literature review is to give an overview of the differences between pure- and crossbreeding systems. Crossbreeding is a mating system with individuals of different lines or breeds. It is one of several breeding strategies in dairy production used to increase the economic profit. The use of crossbreeding increases due to changes in the dairy market and an increase of inbreeding among purebred Holstein. The main benefit of crossbreeding is heterosis, which is the improvement in genetic level in a hybrid offspring above the average of the parent breeds.

Delta X : Utveckling av värmeväxlare
Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more efficient, both in terms of energy consumption but also on a more efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are Literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial Literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the Literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..
