Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Förändring av nitratläckage och växtproduktion från låglänt jordbruksmark vid en ny reglering av vattennivån i Mälaren

The water level of Lake Mälaren has been regulated since the 1940?s. A recentinvestigation suggests that the current regulation needs to be adjusted in order toprevent a decline in water level, salt water from infiltrating from Lake Saltsjön,and risk of floodings. In addition to these preventions, the new regulation couldpotentially effect the natural environment and agriculture practices in the lowlands that surround the lake. The new regulation proposal calls for an increase invariations in Mälaren?s water level during seasons, while the annual mean waterlevel will remain the same.

Elektronikkylning: Datorstödd flödessimulering för nästa generations eSite

I detta examensarbete har termiska förhållanden undersökts för modulen eSite som är under utveckling av företaget Flexenclosure. eSite omvandlar och riktar ström från en mängd olika producenter och skickar denna vidare till förbrukare. Kylning av komponenter tänkta att sitta inuti eSite har simulerats och analyserats. Komponenterna är placerade på en värmesänka, över vilken naturlig konvektion uppkommer. Denna företeelse har undersökts med hjälp av både manuella beräkningar och datorstödda flödessimuleringsberäkningar (CFD) i mjukvaran Ansys® 14.5 och beräkningsverktyget Fluent?.

Idrottande ungdomars attityd till doping : - En studie bland idrottsgymnasister i Karlstad och Torsby

Sports research in the field of social science has shown that regular physical activity leads to wellbeing and positively affects the quality of life. A natural part of being an athlete is learning the functions of the human body, and what?s harmful and destructive, such as drugs (RF 1995). Doping is a constant problem in professional sport. Doping and manipulation of medical preparations in order to maximise performance is one of modern sport?s major problems, according to Blom and Lindroth (1995).I thought it would be interesting to see what the next generation of athletes thinks of doping.

Lärande och bedömning i seminarieform :  - ett examensarbete på A3-nivå om arbetet med seminarier inom ämnet biologi i grundskolans senare år

Denna studie utgår ifrån ett sociokulturellt perspektiv på lärande och syftet med studien är att undersöka huruvida seminarier som arbets- och bedömningsform kan främja intresset för olika moment inom naturvetenskap i allmänhet och biologi i synnerhet, samt att undersöka huruvida seminarier även kan fungera som ett bra bedömningsverktyg. De metoder som användes i studien var enkät och intervju. Studien utfördes i tre moment. Först genomfördes seminarier inom ämnet biologi i en årskurs 8. Därefter besvarades en enkät av ca. 60 elever från seminarieromgången.

Läsförståelse av faktatexter i NO, med stöd av Leselos, en norsk arbetsmodell : En fallstudie av en intervention i årskurs 3

To read and understand are essential competences for everyone in our society; at the same time reading comprehension among Swedish pupils is on the decline. The Swedish school must therefore try to improve their instructions to increase the students' reading comprehension. The aim of the study was to describe how three reading comprehension strategies, if possible, could improve the reading comprehension for the students, including children with learning disabilities, when reading texts of natural science in a third-grade class. The three strategies that were introduced were: to activate prior knowledge, to structure information and to record contents. The questions of the study were: How are the three strategies introduced in the classroom? Can the children with learning disabilities see any benefits for their reading comprehension when working with the strategies? How do the children with learning disabilities experience working with the strategies? Can the teacher see any benefits when working with the strategies? Is it possible to see any differences among the students' results, before and after completed intervention? Method: The results have been collected through observations and qualitative interviews, which make this a qualitative study.

Kommasköldlusen Lepidosaphes ulmi (Linnaeus) i svensk äppelodling : livscykel och naturliga fiender

Lepidosaphes ulmi ? kommasköldlusen har dykt upp som skadegörare i svenska äppelodlingar de senaste åren. Svenska äppelodlare har efterfrågat mer information kring kommasköldlusen och dess naturliga fiender, och därför gjordes denna litteraturstudie. Kommasköldlusen är en pansarsköldlus med ett hårt skyddande skal. Även äggen läggs under skalet och de är därför svåra att bekämpa.

Adoptivfamiljer : "Födelsemeddelande" från socialtjänst till barnavårdscentral

Child health care in Sweden is today automatically informed of newborns in the district and itis therefore natural for the maternal and child health nurses to contact and invite the new family to the child welfare clinic.

The aim of this study was to investigate how social services inform the child welfare clinics of new adoptive families. The aim was also to investigate how and when the maternal and child health nurse thinks that contact should be established and what information/knowledge she feels a need of in contact with new adoptive families. The study has a qualitative design and interviews have been conducted with social workers, a representative of an adoption agency and maternal and child health nurses working in child welfare clinics.

English abstractTitle: Islam and the limitations of the public will of choice.The purpose of this paper have been to investigate how three modern Islamic theorists view the limitations of the public free will of choice based upon their interpretation of the Islamic theology and doctrine.The paper focuses to highlight how all three chosen Islamic theorist interpret the Islamic doctrine based upon my elected theses and more specifically pinpoint were the free will of choice ends, and Islam as a religion starts to take hegemony.

VEM ÄR EN BRANDMAN? : En kvalitativ studie om brandmäns syn på jämställdhet och jämställdhetsarbete.

Gender equality and gender equality work is relevant for today's working life, and previously male-dominated occupations may be increasingly under pressure to become more equal. This paper aims to explore and understand how the firefighters at a station are experiencing gender and gender equality in rescue services.Using theories of how sex is done, how a power perspective and a structural approach can show men's and women's different conditions in an organization, and theories that are more specific to gender and change management the firefighters talk about gender and gender equality are analyzed. Essay results were collected through interviews with seven firefighters and then analyzed and interpreted with the help of theories.The analysis shows that there is a perception among the firefighters that men and women are biologically different and that required physical strength legitimizes the exclusion of women. Inequality is seen as something natural and by pursuing an active gender equality women are given unwarranted benefits. When physical strength becomes a legitimate reason for exclusion, the responsibility for gender inequality is put on women and that women don?t have what it takes.There is also a resistance against gender equality analyzed in the paper, and it's stated opposition seems to be directed against the management's way of recruiting women.
