Aquaculture effluents as fertilizer in hydroponic cultivation : a case study comparing nutritional and microbiological properties

This paper evaluates the prospects for utilizing aquaculture effluents as a nutrient source in organic hydroponic, as is the case in aquaponics. The development of organic hydroponics is dependent on replacing synthetic fertilizers with organically derived nutrients, such as those found in aquaculture effluents. Also, in hydroponic cultivation the establishment of a plant pathogen suppressive micro flora is part of the plant protection strategy. Therefore, both nutritional and microbial qualities of aquaculture water and organic hydroponic nutri-ent solution were analyzed and compared. Results showed both aquaculture water and or-ganic hydroponic solution to be deficient in a number of essential elements, although or-ganic hydroponic solution was closer to recommendations.

Pow-Wow kan inte frälsa hela skolan : Antirasistisk verksamhet på en grundskola

Objektet för min studie är Pow-Wow, en grupp som arbetar mot rasism och mobbning på en svensk grundskola. Syftet med uppsatsen är att genom en kvalitativ undersökning titta närmare på hur Pow-Wow, har startats, genomförts och utvecklats. Utgångspunkten är att liknande grupper som arbetar mot rasism är sällsynta i svenska skolor. Därför är det speciellt intressant att titta närmare på hur det kommer sig att Pow-Wow startades på skolan och varför verksamheten har kunnat överleva så länge. För att kunna besvara dessa frågor har jag intervjuat skolans nuvarande rektor, skolans före detta rektor, de två lärare som arbetar med Pow-Wow och en elev som var med under Pow-Wows första år.

Empowerment: en studie i ansvar, tilltro och ekonomiskt bistånd

Our understanding is that responsibility is shifting from the community towards the individual within the field of social work. This resulted in our essay, which aims to study how the representatives within social service assistance and churches in Helsingborg work with personal power. Our aim is also to illustrate how these representatives view the boundaries of responsibility between the individual and the community. Our questions are: How do the representatives work with personal power from a micro and macro perspective? How do the representatives look upon their position as representatives? What do the representatives consider as responsibility of the individual respective the community? And; Are there preventing factors from individual responsibility? We obtained our empirical material from a qualitative method consisting of interviews.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Konstruktion och implementering av mobil prototyp: The Lovebomb

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

Revisionens betydelse vid kreditprövning : Påverkan ur kreditgivares perspektiv.

Bachelor thesis in business administration with emphasis in accounting and auditing. Spring term 2011, Mälardalens Högskola.Authors:Jim Hansson, Filip Sahl and Pererik Sewerin.Advisor:Lennart Bogg.Key words:Abolition of mandatory auditing, optional audit, auditor, audit.Title:The role of audit in a credit review - impact from the creditor's perspectiveBackground:As of November 1st2010, auditing became optional for micro companies in Sweden. This leads to an opportunity for about 70 % of the joint-stock companies to choose whether or not to keep their auditors. Creditors are affected by this as they may receive a less trustworthy base to make a good credit review if many companies choose to proceed their accountings without the control of an auditor. Creditors have the option to require that companies are to be reviewed by auditors, while authorized accounting consultants may be a possible substitute as a quality control for the accountings.Purpose:The purpose of this thesis is to examine what impact optional audit has had in credit processes so far and look into alternative forms of reviews for businesses.Problem definition:? Does auditing simplify for the creditors in a credit review? ? Is there some kind of accounting that could be a substitute for the audit?Method:The study is qualitative in character through six interviews.

Hur kan mikroföretag bygga upp varumärken? : En studie av vilka faktorer ett mikroföretag kan använda vid uppbyggandet av sitt varumärke.

The purpose with this essay is to study how a micro enterprise builds a brand. This because the current situation makes it difficult to stand out from the vast amount of marketing messages available in the market without having an extensive marketing campaign. Small companies do not have the opportunity to put a lot of recourses as money into marketing as the large companies do. Neither do they afford to repair a brand failure.Brand building is a process that constantly is in progress in a company, large or small. To make this process concrete we have chosen to study the four factors; brand awareness, perceived quality, brand associations and brand loyalty.

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med hjälp av UV-ljus och ozon

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

Svenska mikrolån samt andra finansieringsmöjligheter för småföretag

When a country faces a decline in business activity, companies have to struggle to gain external capital. It is even more important for small enterprises to get capital, as they normally do not have enough collateral to receive traditional bank loans. In Bangladesh, Grameen Bank started with micro credit programs in the early 90?s, that included small capital loans and leasing of machines. Nowadays these micro credit programs have developed to function even in industrialized countries.

A foreign aid dilemma : a study of budget support versus project aid

Foreign aid is a very debated and controversial topic. The most recent studies have focused more on GDP growth and foreign aid correlation, however not much of the debate has focused on what kind of foreign aid should be given. The most common foreign aid is budget support, often a bilateral funds transfer between two countries. This kind of foreign aid can be both conditional and unconditional from the donors? perspective.

Perceptions of domestic solar systems : a study on non-adopter views of a new technology

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

Upplevelser av osäkerhet: En kvalitativ studie av globaliseringens effekter för ungas etablering på arbetsmarknad och familjebildning

Globalization is described as processes of economic, social and political character and a tendency in the field has been to study these aspects of the phenomenon separately. Another common feature of previous studies is to relate to the field at a high abstraction level and talk about the effects and changes in general terms. Such studies of quantitative and statistical nature in which people are constituted as homogeneous groups hides the fact that the relationship between social attributes and context creates unique positions where the effects of globalization are diverse (Sprague, 2005, pp. 16 - 18). The purpose of this bachelor thesis is therefore to break with this entrance to the field and instead focus on a micro level perspective.By conducting a qualitative interview study guided by the globalization theory of the Globalife research team, which shows how structures at the macro level can be understood to affect the micro level, the aim is to reveal potential knowledge gaps within the field.

Multipelt företagande : En studie om företagare med flera företag

Det finns många sätt att studera organisatoriska förändringar på och många författare förespråkar olika typer av checklistor som chefer bör följa för att förändringen ska bli framgångsrik. Denna studie beskriver och analyserar anställdas tankar och handlingar i organisatorisk förändring utifrån individuella erfarenheter, positioner och strukturella karaktäristiska. För att uppfylla syftet studeras två nivåer i ett företag, den reella och den formella nivån. I studien står den formella nivån för ledningen medan den reella nivån står för övriga medarbetare i organisationen. För att studera detta utgår vi från den förändring som Hyresbostäder i Norrköping AB genomför för att göra sin organisation mer affärsmässig och kundorienterad.
