System för fluxpulver vid pulverbågsvetsning ? Utveckling med hantering, kvalité och säkerhet i fokus

Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

Nursing technique and growth environment of Rabbit fish (Siganus guttatus) in the area of Tam Giang lagoon, Thua Thien Hue

SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.

Produktivitet vid stubblyftning :

Stump wood was used between 1850 and 1950 for production of tar and as firewood. In the 1950s the use decreased because of the introduction of the cheap fossil oil. In the 1970s stump wood became an interesting issue again as a raw material for the pulp industry. Stump lifting has today become a possible source for bioenergy. The objectives with this study were to investigate the productivity of stump lifting and stump extraction, and to analyse the economy.

Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten

Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.

Challenges and incentives for sustainable manure management in Russia

The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years. A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed. The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably. The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.

Hur formas ett inlärningsklimat som är framgångsrikt över tid? : En observationsstudie om fotbollstränares beteenden och träningsaktiviteter

Aim and research questionsThe over-all aim of this study was to gain insight info how two male coaches of a specific soccer team behave in a practice environment with regards to educating the players.More specifically, the study sought to map the extent to which said behaviour matched two specific methods of learning; these being Teaching Games for Understanding (TgfU) and Enhanced Guided Discovery (EGD). Research questions: (1) Do the coaches employ the methods and guidelines, which are outlined in the educational plan provided by the soccer association? If so, what form does this application take in practice? (2) To what extent and in what ways do the coaches utilize feedback and questioning techniques in the education of players? (3) What similarities and differences in behaviour can be identified between the chosen soccer team?s two coaches?Method: The data for the study was collected through field observation. The subjects were two youth elite soccer coaches and observation of these coaches took place during five regular practice sessions on the soccer field. All data gathering and analysis were carried out using a modified version of the Coach Analysis and Intervention System (CAIS).

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Mätning av prestation i tekniska moment i fotboll : ett testbatteri genomfört av juniorer på elitnivå

SammanfattningSyfte och frågeställningar: Syftet med undersökningen var att ta ett första steg mot att skapa ett testbatteri, som objektivt kan mäta fotbollspelares tekniska prestationsförmåga med boll, samt konstruera en rad övningar som innefattar viktiga fotbolls-specifika tekniker och testa dessa övningars reliabilitet genom ?test-retest?. Syftet med studien var också att göra en jämförelse i prestation mellan varje spelares dominanta och icke-dominanta fot, från tillslagsövningar där båda fötterna används.  Metod: Tolv herrjuniorer (16-19 år) och sju damjuniorer (15-17 år) på elitnivå genomförde ett testbatteri bestående av totalt 21 övningar för mätning av de fotbollsspecifika teknikerna nick, mottagning, driva med boll samt tillslag. Åtta av männen (16-19 år) återgenomförde testbatteriet för utvärdering av testbatteriets reliabilitet.

Motorväg till det omedvetna? : Fem psykoterapeuters upplevelser av att lära sig arbeta med Intensive Short-Term Dynamic Psychotherapy

Inledning: Psykoterapeutiskt arbete med bearbetning av omedvetna känslomässiga konflikter innebär ofta terapiprocesser som varar över lång tid och kan bedrivas med skiftande tekniker. Psykodynamiskt inriktade terapeuters arbetssätt speglar deras teoretiska övertygelse och personliga läggning. Många arbetar intuitivt och med ett eklektiskt förhållningssätt. Att arbeta efter en sekventiell, tydligt formgiven metod är ovanligt inom den dynamiska/analytiska traditionen. Syftet med studien är att undersöka fem psykoterapeuters upplevelse av att lära sig arbeta efter en specifik metod med fokus på affekter; Intensive Short-Term Dynamic Psychotherapy.

Svenska Kraftnät är ett statligt affärsverk vars huvuduppgift är drift och underhåll av det svenska elstamnätet. Bekämpningen av oönskad vegetation är en del i underhållsarbetet i anläggningarna och sker i dagsläget med det kemiska bekämpningsmedlet Roundup. Svenska Kraftnät önskar att minska eller ersätta den kemiska ogräsbekämpningen med en miljöanpassad metod och rapporten syftar till att undersöka den möjligheten.  En av de möjliga metoderna, NCC Spuma, testades i ett fältförsök i en av Svenska Kraftnäts anläggningar och dess miljöpåverkan undersöktes genom en livscykelanalys.NCC Spuma är en termisk metod för ogräsbekämpning som erbjuds av NCC Roads. Ogräset bekämpas med hett vatten och ett isolerande skum. Det isolerande skummet förlänger tiden det heta vattnet skadar ogräset.

Methods for Locating Distinct Features in Fingerprint Images

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.

How to build a rein tension meter

A large part of the interactions between horse and rider during horseback riding takes place through the reins and the bit and devices for measuring the tension on the reins, rein tension meters, has fairly recently been developed. To safeguard the welfare of the ridden horse riders need to be aware of the rein tension they apply and actively work to decrease it. Furthermore, there is a need to develop the study of rein tension through new techniques and refined analysis procedures. A good-quality rein tension meter should be small in size, sensitive, durable and as accurate for light rein tension as for strong forces. Rein tension meters used in research on horse and rider interaction commonly depend on strain gauge technique for generating rein tension data.

Green feed in the marine fish farming : how to communicate water benchmarks to stakeholders

Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

Svårklassryttares förberedelser för dressyrträning : för bäst lärande

SUMMARYThere was no previous study in what high level dressage riders had for ideas of how to best prepare for their training sessions with an instructor. Neither any study of how high level dressage riders seemed to be more or less susceptible to the instructions from their instructor during their training sessions. If the sport had more knowledge about this, it might result in more riders on a higher level. The purpose of this study was to find out how high level dressage riders are preparing themselves for the best result for an instructor led training session and how they could bring as much as possible instructions from the coach. The two questions of the study were: How are high level dressage riders preparing themselves for a training session with an instructor, practically and mentally, and how can they affect their susceptibility to instructions?The study was carried out both by reviewing existing literature and studies in general education and pedagogy in the riding education, and by a qualitative interview study of six dressage riders who rode on a difficult level at the competitions, during the year of 2009.
