Identifiering av parametrar för tillståndsbedömning av en vattenkraftstation

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

"Hjälper mig att förstår vad text handlar om" : en undersökning av två skolexterna läxläsningsverksamheter

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

Modulär Mekanikstruktur för Nanosatelliter

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

Kvalitet i brödvete :

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

Nautisk turism : en jämförelse mellan svenska och kroatiska förhållanden

AbstractA tourism genre that has developed in recent years is the nautical tourism, nautical tourism is described as a tourism genre that includes all activities in relation to water. Croatia is one country that has invested in and has good presumption for this type of tourism, and has also received an international recognition as a top destination within the nautical tourism genre. The purpose with this thesis is to increase knowledge about the nautical tourism development in Croatia, and to see if it would be possible to develop on Swedish conditions. Sweden is a destination with a large number of archipelagos, located in both inland lakes and along coastal areas. Stockholm archipelago is one of the world's largest archipelagos which has a long tradition as a tourist destination.

Dagvattendammars reningseffekt : påverkande faktorer och metodik för statistisk modellering

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Den interna informationshanteringen inom äldre- och handikappomsorgen i kommundelen Viskafors

The purpose of this thesis is to explore how the internal information processing and management is carried out within a unit of Viskafors municipality. Furthermore, to explore and make recommendations of how the organisation can improve its internal information management. To get a full picture I have interviewed people at different levels of the organisation. The main findings showed that there was a dysfunction in the internal information processing and management. For example the study showed that the internal information did not reach out to the different parts of the organisation due to insufficient information processing.

Bolagsstyrning : En kartläggning av styrelsers arbete med strategifrågori svenska börsnoterade bolag

Corporate governance intensified due to the corporate scandals in the USA which led to a new law the so called Sarbanes-Oxley Act (SOX).In 2005 the "Svensk kod för bolagsstyrning" (The Code) was introduced. The main purpose of The Code is to strengthen the confidence in Swedish companies quoted on the Stockholm Stock Exchange. The Code focuses on the working process of boards. The rules set by The Code places higher demands on the board.  Among many other duties the board has to establish long term operational goals and strategy.

Kombinationsträningseffekter på fysiologiska egenskaper relevanta för handbollsprestation på elitnivå. : En experimentell interventionsstudie på manliga elithandbollsspelare under tävlingssäsong.

Syfte och frågeställningar: Syftet med denna studie var att undersöka de fysiologiska effekterna av kombinationsträning, innefattande styrketräning, contrast complex training (CCT) kombinerat med intervallträning i form av upprepade kortare sprintar (ca 6 s) (RSE) eller längre (30 s) högintensiva intervaller (HIIT) hos handbollsspelare i herrelit, under tävlingssäsong.Metod: Under 12 veckor, i tävlingssäsong, genomförde 15 elithandbollsherrar, utöver sin vanliga handbollsträning antingen RSE (n=8) bestående av 10 repetitioner av shuttle sprintar (2 x 15 m) med start varje minut och med passiv vila eller HIIT (n=7) bestående av 5 reps av 30-s all-out sprintar med riktningsförändringar. Båda grupperna genomförde ocksåCCT bestående av 3 set med 3 övningar (3 x knäböj 90 % av 1RM, 6 x jump squat med 50 % av kroppsvikten, 6 x dropp jump från 30 cm Pre- och posttesterna inkluderade jump squat (JS) (RFD (Ns/kg)), 5 jump for distance test (5JT) (m), 30m sprint (5m (s), 20-30m (m/s), repeated shuttle sprint ability test (RSSA) (RSA Bäst, Sämst, Tot (s) samt beräknat trötthetindexFI (%), Sdec (%)), 1 RM knäböj (koncentrisk) (kg/kg kroppsvikt), Yo-Yo intermittent recovery test (YYIRT 1)(m) and maximal syreupptagningstest (VO2max) (l O2/min, ml·kg-0.75·min-1). Resultat: Båda grupperna ökade signifikant maxstyrkan i knäböj, RSE gruppen (8,8 %) mer än HITT (7,4 %) (p<0.01). I motsats visade HIIT gruppen större förbättringar i rate of force development (RFD) (63,3 %) än RSE (56,3 %) (p<0,05). VO2max ökade signifikant och likartat i båda grupperna (~2%).

Svarar människor mer eller mindre socialt önskvärt beroende på hur de genomför ett personlighetstest?

A personality test is a useful tool in recruitment contexts. Studies have shown that participants distort their answers in a socially desirable manner. The purpose of this study was to investigate if people respond more or less socially desirable depending on how they rate themselves in a personality test, based on the "big five" personality dimensions.Eighty people, (40 women and 40 men), 19-42 years, (M= 24,1 SD= 3,76) rated themselves on a personality test. Group one, (20 women and 20 men) completed the test on paper. Group two, (20 women and 20 men) completed the test verbally.

Gårdsbaserade system för spannmålshantering i den framtida Lantmännenorganisationen :

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

Självskadebeteende och riskbeteende för ätstörningar hos tonåringar: förekomst, samband och intervention med expressivt skrivande

The purpose of the present essay, as part of the project Self esteem and Life circumstances among teenagers, was to investigate the rate of both deliberate self-harm (DSH) and risk behaviour related to eating disorders in 14-year-old swedish adolescents, gender differences in DSH, and possible correlations between DSH and risk behaviours related to eating disorder. In addition, the effects of expressive writing (Pennebaker & Beall, 1986) on DSH and risk behaviours related to eating disorders were investigated. Data from two pilot studies are included. In total, 198 14-year-olds from four different schools in southern Sweden participated. For the purpose of measuring the rate of DSH, a simplified version of Gratz's (2001) Deliberate Self-Harm Inventory (DSHI) was used.
