Giraffens blodtrycksreglering

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Kriminalvårdens rehabilitering : Om viljans betydelse för att förhindra återfall i brott

Genom historien har frågorna om hur man får människor till att inte begå brott, hur man bäst straffar en brottsling och hur man får brottslingen att inte begå brott igen diskuterats intensivt. Om man tittar tillbaka i historien har kroppsbestraffning och dödsstraff varit de centrala straffmetoderna. Det var först på 1800- talet som tanken om att brottslingars själ skulle straffas istället för kroppen. Det var med denna tanken som fängelsestraffet blev en central del. Bakom murarna skulle fångarna inte bara straffas för sina gärningar de skulle också formas till en människa samhället ville ha.

Mekaniserad ungskogsbehandling för röjning och skörd :

Earlier attempts at mechanising pre-commercial thinning have been met with varying degrees of success. Most attempts have been based on techniques where residual stems are straddled. Early treatment is essential to limit damage on residual trees. One part of the present study is an evaluation of mechanised pre-commercial thinning using the new Vimek 404R. Vimek 404R is a fairly small machine that permits selective removal of stems, making it potentially suitable also for areas overdue for pre-commercial thinning. The study established the level of performance for the machine, as well as the improvement needed to make it an economically viable option.

?IDAG ?R JAG LIKA MYCKET SVENSK SOM CHILENARE? En antropologisk studie om stulna adopterades upplevelser av identitet och utanf?rskap i Sverige

In recent years, revelations about illegal international adoptions have made headlines around the world, and one notable country where many illegal adoptions have been facilitated is Chile. To find out that one's adoption wasn?t facilitated legally is a shock for the individual that raises many new questions about themselves and their origins. This study intends to examine how the identity of stolen adoptees has changed in their adulthood after they have found out that they were stolen, as well as to investigate how they experience alienation in Sweden from their position as both stolen and non-white adoptees. Qualitative methods have been employed in this study: participant observation, semi-structured in-depth interviews, and informal interviews.

Inventory and evaluation of Nairobi Animal Orphanage : focusing on Congo Grey African parrot, cheetah and rehabilitation

This BSc thesis is a part of an initial step of a collaboration between Skansen and Kenyan Wildlife Service (KWS) and constitutes of an inventory of the Nairobi Animal Orphanage run by KWS. Animal Orphanage takes care of orphaned and injured animals arriving from throughout Kenya. The project started out as a refuge and as a temporary place for animals in need of care and help. With time it has evolved to an establishment that resembles and functions more like an animal zoo. The aim of this inventory is to focus on how the biological needs of Congo grey parrots ( Psittacus erithacus erithacus) and cheetahs (Acinonyx jubatus) are met, in terms of management and housing.

Riksintresse; Bevarande eller nyttjande : Vindkraftsutbyggnad inom Natura 2000- områden

Natura 2000 is part of the European Union: s framework to protect and preserve biological diversity. Natura 2000- areas are by the goverment appointed to areas of national interest for preserving nature. Also wind power stations are appointed as of national interest and the reason for this is the goverments goal to get energy from reneweble energysources. This essay describes when both these intrests conflict eachother when it comes to building wind power stations within Natura 2000- areas. The main focus of this essay is a casestudy of two cases from two different counties, Dalarna- and Norrbotten county, where applications have been made to build wind power stations within existing Natura 2000- ares, both cases have reached the court dealing with enviromental issues.

Vattenvård vid slutavverkning : före och efter vattenvårdsutbildning på Stora Enso Skog, distrikt Siljan

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

Djup icke vändande bearbetning i sockerbetsodling :

A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.

Industriella avloppsvatten i Chile : Identifiering av problem samt förslag på åtgärder

Chile and Santiago are struggling with heavy environmental problems as a consequence of urbanisation and industrialisation. In the Santiago region the air is seriously contaminated and most of the rivers are classified as heavily polluted.The aim of this thesis is to survey the industrial fluid waste situation in the Santiago region and to make suggestions on technological improvements or process changes. The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

Jämställdhet, jämlikhet, olikhet : kunskap om skolans jämställdhetsarbete

This essay is about gender equality in a Swedish upper secondary school. The aim is twofold: to obtain knowledge about feminism, gender equality, boys´ and girls´ situations in schools and gender equality work there; and to find out if government management documents for schools work effectively when it comes to promoting gender equality in schools. There are four research questions: How do teachers interpret what´s said in management documents for schools? What strategies do teachers use to promote gender equality? What opportunities and obstacles do teachers see for promoting gender equality at the specific school? And, finally, do the management documents for the school work effectively when it comes to promoting gender equality?The study has a socialist feminist perspective, which sees gender differences as a result of a mix of biological, historical and social factors. Important theoretical standpoints include gender socialization as an explanation for how girls and boys become women and men.The results of the study points out that teachers interpret management documents differently, and that they find the documents hard to understand.

Varför förstår inte mamma? : En kvalitativ studie om barn till föräldrar med utvecklingsstörning

The aim with this study is to through a research summary review experiences of growth and theparents caring ability among children who has grown up with parents having intellectual disabilites,and by empirical data illustrate how these persons today describe their childhood, their parentscaring ability and other cicumstances that have affected the growth. The results from the researchsummary are then to be compared with the results from the empirical data in purpose to reviewsimilarities and discrepancies.The study has a qualitative approach and it is based on foundings from earlier research andinterviews with four women whos mothers have intellectual disabilities.In the existing research of this issue there is a clear dichotomy between whether the researchershave focused on either the children or the parents. In both perspectives there are differentconceptions about whether a person with intellectual disabilities have the capacity to care for andraise a child, as there is about how the parents intellectual disaparment affects the child.The womens stories of the childhood are obviously unique, but they also have many experiencesin common, both among themselves as with what has been found in research. Children of parentswith intellectual disabilities have been classified as a risk group, wich has been shown by reversedroles for child and parent, lack of attachment to the parents and by insufficient care. Despite thedifficulties that the women have faced, they describe many parts of their lives in positive termstoday.There seems to be other influences in addition to the parents intellectual capacity that affect theesechildrens outcomes.

Bärare av mat : Arbetsfördelning och könsskillnader i restaurangbranschen utifrån ett genusperspektiv

The distribution of work related tasks depending on gender leads to different appraisal depending on which gender is performing a task. This aim of this research is to study how gender differences influence task allocation within the restaurant industry. The study is inspired by a discourse analysis perspective complemented by constructivist and critical pragmatic theory. Interviews were conducted in two focus groups with seven participants in total. The analysis is divided into four sections which answer six discourse analytical questions using the interview material.

Gymnasieelever och fostran av demokratiska medborgare : En enkätstudie av elevgruppers nivåer av moraliska och kognitiva utveckling.

This study is grounded in an interest in the Swedish Upper Secondary Schools? role as an educator of democratic citizens, with a specific interest in the moral and cognitive development of Upper Secondary School students. Development in these two areas is treated as results of citizenship education.The purpose of the study is to examine moral and cognitive development of students in Upper Secondary School to see if there are any structural differences to be found between the Upper Secondary School programs that are vocationally oriented and the programs that are preparing for further studies on higher levels ? since these differences have been both theoretically and empirically implied. The study is based on an enhanced version of Lawrence Kohlberg?s stages of moral development (with teachers? evaluations of students? capacity as a reference point of the students? actual level of moral development) as well as on Kieran Egan?s theory of development through the use of cognitive tools (as seen in five different ?shapes of understanding?).

Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor

In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.

Respons av laktoferrin i ostimulerad helsaliv och kapillärt C-reaktivt protein vid experimentellt inducerad gingivit.

Bakgrund: Gingivit kännetecknas av svullet/lättblödande och ibland ömt tandkött. Gingivit är en inflammatoriskt orsakad reaktion som uppkommer i samband med närvaro av bakterier. För att motverka utvecklingen av gingivit rekommenderas munhygienvård regelbundet. Gingivit kan utvecklas till parodontit med skador på upphängningsapparaten och benstödet, orsaken till detta är idag dock ej helt klarlagd. Kliniska variabler (blödning vid sondering) är vedertagna diagnostiska metoderna för diagnostisk av gingivit idag.
