Hur påverkas muskelaktiviteten vid styrketräning med en tjock stång i jämförelse med en standardolympisk stång? : En EMG- studie
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).
Utvärdering av sjökalkningens eventuella effekter på öring och röding i jämtländska fjällsjöar
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.

UTFACKNINGSVÄGGAR : En jämförelse mellan platsbyggda och prefabriceradebyggmetoder
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.
Luftprovtagning samt analys av mono- och diisocyanater
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.
Lyfta Lätt Tekniskt hjälpmedel för pakethantering
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.
Upplysningar om nedskrivningsprövning av goodwill enligt IAS 36 p.134 : Ur ett finansanalytikerperspektiv
En diskussion har länge förts kring hur beräkning av goodwill ska ske. Detta framförallt eftersom goodwill är en komplex tillgång som är svår att identifiera och separera från andra tillgångar. Sedan 2005 tillämpas nedskrivning av goodwill enligt IAS 36 för noterade företag. De krav som återfinns i IAS 36 p.134 har enligt tidigare studier visat sig vara svåra för företagen att följa. Kraven anses motsvara kapitalmarknadens informationsbehov.

Claw and leg lesions in preweaning piglets : a comparative study of piglets reared on structured polyurethane coating and piglets reared on concrete floors
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.
Utbildningens betydelse för våld i nära relationer. En litteraturbaserad studie om associationen mellan kvinnors utbildningsnivå och våld i nära relationer i låg- och medelinkomstländer.
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.
Introduktion av förstakalvare i AMS : en enkätstudie
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.
Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure
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.
Hur bör unga hundar av storvuxna raser utfodras?
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.
Ultraljudsundersökning av muskelskelettära strukturer på hund : en litteraturstudie och en fallstudie av hundar undersökta vid Universitetsdjursjukhuset SLU jämfört med fall undersökta vid andra djursjukhus runt om i världen
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.
