Many everyday tasks and also many sports require good grip and forearm strength. Everything from carrying boxes and lifting a child to grab the arms and legs in various martial arts, or holding a tennis racket involving the hand and forearm muscles in various ways. It is therefore important to train these muscles to prevent Injuries and congestion and to perform well in sport. A well known way to train functional strength in the hand and forearm muscles is weight training with thick handles. The purpose of this study was to investigate the differences in muscle activity in the upper arm and forearm muscles as well as the deltoids between two bars of different diameter (28mm and 57mm) in two different weight training exercises using electromyography (EMG).

Enligt rapporter från Arbetsmiljöverket är arbetsrelaterade besvär som inte beror på arbetsplatsolycka vanliga inom trädgårdsnäringen. Orsakerna till besvären är huvudsakligen en följd av påfrestande arbetsställningar, korta upprepade arbetsmoment och tung manuell hantering. Syftet med denna litteraturstudie var att beskriva vad trädgårdsmästare bör tänka på vad gäller belastningsergonomi för att minska risken för skador i sitt arbete. Sökningar gjordes i databaserna Medline via PubMed, ScienceDirect och Academic Search Elite med sökorden horticulture, gardening, agriculture, ergonomics, pruning, shoveling, stoop, lifting technique and musculoskeletal Injuries.Resultatet visade att när det gäller lyftteknik och arbetsställningar bör man i möjligaste mån undvika att utföra dessa med en framåtböjd överkropp och raka ben. Denna kroppshållning visade sig vara sämre i jämförelse med andra tekniker och kroppspositioner med hänsyn taget till påfrestningsgraden av ländryggen.Även vid grävning finns per automatik ett starkt inslag av att luta sig fram med böjd överkropp med den följden att ryggen utsätts för krafter som kan vara skadliga.

Bakgrund: Idrottsskador ?r vanliga i lagidrotter som handboll och innebandy. Trots att skadepreventionstr?ning ?r effektiv ?r f?ljsamheten ofta l?g. Spelbaserad tr?ning har visat positiva effekter p? motivation och engagemang i andra sammanhang, men hur idrottare uppfattar spelbaserad skadeprevention ?r inte unders?kt.

In conjunction with today?s increasing competition within the construction sector, more pressure is being placed on building contractors. Efficiency and improvements are necessary but without impairment to an ergonomic and safe construction site. This in is in order to reduce the construction costs and time but to retain the ability to deliver a high-quality contract.Various methods and prefabrication degrees are used, depending on the project's requirements and conditions. This analysis sets out to investigate and exhibit what qualifications are important when choosing a construction method for curtain walls.Advantages and disadvantages with each method have been analyzed and recommendations have been given to show when different methods are best suited.

When exposed to them, isocyanates can induce serious Injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

People working with handling parcels in terminals are often victims of musculoskeletal Injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

Floor surface in pig facilities can have an impact on animal welfare and pig health, as it can cause the pig physical damage and thereby increased risk of infectious diseases and lameness. The development of pig housing systems has resulted in a decreased use of bedding. It seems hard to find the optimal floor in farrowing pens, as it must suit both the sow and piglets. The floor friction needs to be adequate to avoid slips and at the same time should the floor be non-abrasive. Abrasions and lesions caused by the floor are not only causing the animal suffering, but are also negative from an economical aspect.

Introduction: Intimate partner violence (IPV) is a great public health issue that can cause serious physical, psychological and psychosomatic Injuries to the woman. Education is one out of many important protective factors against IPV. Aim: This study aimed to investigate the association between women?s educational level and IPV in low- and middle-income countries, the interaction between the education of the woman and the man and IPV, how education on different levels (individual-, family- and community-level) influences IPV and how gender is connected to education and IPV. Method: A literature-based study with 12 selected scientific articles as the foundation for the analysis was performed.

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein. The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.

Ultrasound is a well established diagnostic method in small animal veterinary practice but there appears to be limited use of ultrasound for evaluating the musculoskeletal system. The aim of this study was to investigate what publications exist concerning musculoskeletal ultrasound of dogs and to compare the use of musculoskeletal ultrasound at the University Animal Hospital (UDS) in Uppsala, to other animal hospitals in the world. The literature review is divided into three parts, the front leg, the hind leg and miscellaneous. The literature review focuses on the musculoskeletal abnormalities that can be seen with ultrasound. The front and hind leg sections are mainly focused on the joints.

The trotting in Sweden has a good reputation in an international view, both in the perspective of success and how the sport is managed with focus on security, animal protection and animal welfare. A large number of equipment details are fitted on the horses during training and competition. The Swedish law of prevention of cruelty to animals regulate training and competition with racehorses, and propose to protect horses from unnecessary suffering. The equipment permitted in races is regulated in Tävlingsreglementet (The Regulation of Competititon) and in the regulations of equipment, that the Nordic Regulation Committee and Nordic Animal Welfare Committee have worked out. Due to training and competition the equipment must even meet the Swedish law of prevention of cruelty to animals. However, the behaviour or the senses of the horses is often affected by the equipment due to the way the equipment corrects, modifies, restrains or reduces the behaviour of the horse, which may cause the horse stress or discomfort.

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses. The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.

Single vehicle accidents are one of the most common types of accidents that occur on the Swedish road network. Depending on the design of the road, the presence of a crash barrier and embankment on the roadside, the outcome of a roadside collision can lead to serious Injuries and even deaths.The aim of this project is to investigate the possibility of improving road safety by designing the optimal roadside area based on the results of a life cycle cost analysis (LCC).The questions that have been answered during the duration of this project are:1) Describe the current technical solutions for roadside area design and the various barrier types used in Sweden.2) Complete an existing mathematical model that has been developed by Hawzheen Karim, for calculating life-cycle costs for various roadside areas.3) Calculate and compare the life cycle costs for the side area with a barrier and without a barrier.By performing an analysis of the documentation on the current guidelines and rules for shaping the roadside, was it possible to describe the current technical solutions for the formation the roadside as well as the current roadside barriers in use today. A mathematical model for calculating the life cycle costs of different barrier types had already been developed by Hawzheen Karim. This model was supplemented so that it could calculate life-cycle costs of the roadside region with and without a barrier. After the model was completed, an analysis was performed to obtain life-cycle costs of a roadside with and without a barrier.The result showed that there is a clear relationship between the slope inclination, fill height, and the rate at which the costs rise.
