Introduction: A complex interaction between muscles, tendons, bones, joints and nerves are required for optimal function of the human hand. It is known that an individual?s grip strength is vital for performance of physical demanding tasks such as strength training with free weights. Strength training including a thicker grip around the bar may enhance the strength of the grip in the athlete without other special routines for grip strength development. The purpose of this investigation was to examine the difference in performance in multiple repetitions in two strength training exercises using two different sizes on the bar, to look for correlations between grip strength of the subjects hand and the amount of repetitions executed with two different size of the bar and finally the correlation of hand size and the amount of repetitions executed with two different size of the bar.Method: 15 strength training men (23,9 ± 4,1 years), underwent measurements of hand size, maximum grip strength, 1 repetition maximum (1RM), a 80 % of 1RM weight strength test with two different  bar sizes.Results: The results from the present investigation indicates a 21,1 % reduction of 80 % of 1 RM weight performance in repetitions executed in the bench press with the thicker diameter of the bar and a 66,2 % reduction in repetitions executed with a 80 % of 1 RM weight in the lying bench row with the thicker diameter of the bar.

Examensarbetet undersöker prestandakostnader och flaskhalsar för spelgrafik samt beskiver vanliga optimerings tekniker som tillämpas i industrin. Rapporten ger sig på uppgiften att visa exempel på prestandakostnad. Det framgår att dagens spelgrafik är för komplex och situationsberoende för att komma med annat än enkla abstraktioner man kan använda sig att göra en estimation på prestanda..

Laminitis is a debilitating disease causing much suffering to horses and ponies all over the world. It is manifested in the hooves as a mechanical failure of the suspensory apparatus between the hoof capsule and the distal phalanx. Due to the weight of the horse the disease may result in a dislocation of third phalanx. Six healthy standardbred trotters were used in this study on whether standardbreds tolerate forced recumbency as well as Shetland ponies. Recumbency was induced pharmacologically but maintained only by lowering the ceiling height of the box to a height of approximately 125 ? 140 % of the horse´s thoracic height.

This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos. Chemical analyses and yeast counts were performed for fresh crop and silage.

AbstractTitle: The effect of caffeine on performance during resistance training ?A systematic overviewAuthor: Amanda Jonsson and Erica BenderSupervisor: Mette AxelsenExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: 2015-03-31Background: Products with high content of caffeine has in recent years become popular for optimizing physical performance. Caffeine affects mechanisms in our body which can be beneficial to perform better during exercise, but the theories have not yet been systematically reviewed.Objective: The purpose of this review article, is to examine the acute effect of caffeine intake before strength training on athletic performance with the outcome muscle endurance.Search strategy: A systematic literature search in databases PubMed, Scopus and Cochrane using keywords: ?Caffeine?, ?strength?, ?muscle?, "resistance training", "muscle strength", "strength training", "athletic performance", ?repetitions to failure?, ?muscular endurance? and ?endurance training?.Selection criteria: Healthy subjects, 16-50 years old, with experience in strength training. Studies with a caffeine intake > 5 mg/kg body weight, which participants performed dynamic strength exercises on a weight > 60% of their 1 RM.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

We all know that water is very important for both animals and humans. When we are weaning the piglets from the sow we must guarantee that the piglets can start to drink more water instead of sow milk. The first thing to check is always the quality of the water that is to be used. To secure that, you must take a water sample. If the water is inadequate it can bring a lot of problems and diseases.

The purpose of this paper has been to find out what motives buyers of forest property has for there purchasse, what competence they have in economics and forestry, and what analysis they had done before the purchase. The study is based on interviews with nine different buyers from two geographical areas, five from Hälsingland and four from Småland/Skåne. A forest property is a property where the value to 100 % consist of forest. A part from the interviews every purhase has been analysed in comparison to an estimation of the yield value. The theoretical yield value was estimated with a computer programme.

Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer.Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok.Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå.Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare.Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation. .

The subject for our bachelor thesis is how sugar is portrayed in Aftonbladet. By analyzing newspapers from 1995 and 2013 we wanted to research if the portrayal of sugar has changed during the years. We have noticed that there is a trend of being healthy and fit today. ?Strong is the new skinny? is a quote we can see in social media and on blogs today.

Laminitis is a common but devastating condition, and affected horses are often euthanized or influenced a very long time. Many horses never return to their original capacity. Laminitis is often associated with severe pain and a long time of convalescence. Symthoms includes lameness, hoof hyperthermia, strenghthened digital pulse and pain. The horse often tries to move the body weight away from the forelegs which are often more severly affected than the hindlimbs.
