Vertical jumping ability is an essential skill in many sports. The aim of this study wasto investigate the acute effects of assisted jumps on subsequent countermovementjump (CMJ) performance by female athletes. Nine healthy, trained female subjectsvolunteered to participate in the study. In a randomized order, they performed oneregular warm up protocol before testing their CMJ baseline value, and one warm upprotocol with an addition of five assisted jumps at 30% body weight reduction beforeanother CMJ test. Elastic cords attached to an overhead pulley system and to aharness around the subjects' upper body were used to reduce the body weight.Significant improvements were noted in jump height, 2.3 cm (7%), positive forceimpulse, 4.7 Ns (2%), vertical take off velocity, 0.1 m/s (3%), countermovement time,0.1 s (12%) and breaking time, 0.1 s (14%), p.

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

Background: Pressure ulcers have during a long time ages caused great suffering for the patients. The factors affecting the occurrence of pressure ulcers can be both internal and external, such as immobility and malnutrition. Nurses´ role is to assess risks and thus pay attention to prevent and treat pressure ulcers. The nurse may use various assessment tools to highlight and document patients at risk for developing pressure ulcers. Aim: This study was to describe health professionals´ thoughts and actions about the pressure ulcers.

The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.

The purpose of this qualitative study is to investigate how some teachers make use of the results of the national tests in mathematics to plan their teaching. The questions are how they plan their teaching in mathematics and if they use the results of the national tests to compare with their own teaching.   Five teachers in mathematics has been interviewed. I have used unstructured interviews with open-ended questions, and I have been able to ask follow-up questions based on their answers. The analysis of the survey is made from a systems theory approach.  The result of the survey shows that teachers make use of student performance to look at their own teaching of the current group of students. However, there is not enough time to rehearse and repair the deficiencies discovered in the national tests, which for some is perceived as a stress factor.

Nowadays the majority of the thinnings made in Swedish forests are done by machines, harvesters and forwarders. The most common model in thinning with a harvester is strip-road operated thinning and stand-operated thinning with one intermediate passage between the strip-roads. This study is a time study with some quality follow ups on a strip-road operated thinning model, a stand-operated thinning model with one intermediate passage between the strip-roads and a stand-operated thinning model with two intermediate passages between the strip-roads. The machines in the study were a small harvester (Forestline MPM C90) and a medium sized forwarder (Timberjack 1110). The study was made in Litsnäset outside the city of Östersund in Sweden and was made during the autumn 2007. In a lodgepole pine stand six study units (0,6 ha) were thinned with the three different models, two study units per model.

The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer. The purpose of the thesis was to examine the link between CEO compensation and corporate performance measured as a change in Market to Book ratio. Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.

The control of indoor temperature must be able to handle large time constants and both measureable disturbances like outdoor temperature, and non-measurable disturbances, like waste heat from appliances. Due to cheaper microcontrollers (small computers with designated tasks) with better performance, more advanced and computation-demanding methods for control can be used.In this thesis, Generalized Predictive Control (GPC) has been implemented and tested on a theoretically derived model of a house. GPC states that a model of the system is estimated in every sample, and the control is carried out simultaneously, based on predictions of the model. Disturbances like solar radiation can be estimated and used in the control as well. The control signals are determined by quadratic programming, which makes it possible to consider conditions, for example limitations on the control signals.GPC requires a number of parameters to be defined, like model order and control signal penalty, but is relatively robust for variations in them.

Syftet med studien var att utifrån Lundqvists tre förutsättningar för en lyckad implementering undersöka om det uppkommit några implementeringsproblem inom socialtjänsten på grund av att kommunledningen regerar med en oppositionsbudget. För att besvara syftet ställde jag därför upp en frågeställning som utgår från Lundqvists tre villkor. Frågeställningen löd:- Har det uppkommit några problem inom socialtjänsten med att förstå de politiska besluten, kunna implementera de politiska besluten, eller vilja implementera de politiska besluten, på grund av budgetsituationen?Denna frågeställning, och därmed även mitt syfte, har jag önskat besvara genom att jämföra den uppkomna budgetsituationen med hur implementeringsarbetet såg ut vid normalfallet, det vill säga där kommunledningen regerar med sin egen budget. Detta har jag gjort genom att föra samtalsintervjuer med, för studien centrala, aktörer inom politiken och förvaltningen.Jag konstaterar utifrån dessa intervjuer att jag genom min studiehar fått vissa belägg för att budgetsituationen har bidragit till en del implementeringsproblem för socialtjänsten som inte har funnits före oppositionens budget började gälla.

This study examines whether the ownership structure of Swedish firms contributes to explain the variations in executive pay. A regression analysis was performed on 102 companies listed on the Stockholm Stock Exchange. The analysis suggests a negative relationship between ownership structure and executive pay after taking company profitability and size into account. The result is in line with previous studies and the agency theory. This indicates that large shareholders have a stronger position in Swedish companies or that large shareholders monitor the management to a larger extent, rather than providing incentives.

The purpuse with this work is to see if there is a possibility to buy a farm with a low amount of own capital. We have been doing budgets for five farms with different kind of productions. Some of the farms in this work are possible to buy with a low amount of capital but if you start without any money you will run into problems with the bank. The bank is not very pleased with fully financed projects; they would recommend an own capital of at least 10-20%. The farms with the best budgets were farms with animals..

The purpose of this study is to provide a description of how mathematics teachers in grades 3 choose to work with mathematics and how it affects of student performance in national tests. The categories I will use are outdoor education, textbooks, learning materials and problem solving. Laboratory materials can be everyday materials and educational materials in which pupils have an abstract understanding of the subject. This survey was conducted through interviews and observations. The survey was also conducted in relation to student performance in national math tests.

The purpose of the thesis project has been to use scientific methods for product development inorder to design a multi device that supplements Silva?s range of products.The project followed a product development process divided into four phases; Market Analysis, ConceptCreation, Concept Development and Construction.

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.
