Hur påverkasogräsuppkomsten av jordbearbetning :
Today it is common to spray against most weeds by using very expensive weed-killers.
The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers.
Therefore it is in everyones interest to find other methods to fight the weeds.
Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose.
Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%.
To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night.
By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..
Talande tystnader om heder : En analys av socialsekreterares och förvaltningsrättens bedömning genom rättsfall av hedersrelaterade LVU-ärenden
One of the social services primary missions is to protect children from suffering harm. Social service work should work based on the child?s best and have the child's perspective in mind. In all cases involving children, the focus is on the child's needs and interests and is regulated in Convention on the Rights of the Child (CRC). Both of the previous research and this study reveal the various markers that are evident in the social services handling of honor related cases.

15 years of age) who are struggling with mental illness. Focus on mental illness is
discussed in a school context. From the school counselors perspective questions
like, what kind of working methods are they using and, how they collaborate are
examined. The research design is based on a qualitative approach, with ten Semistructured interviews with ten different informants who work as a counsellor at 10
different schools around Skåne.
Aquaculture : animal welfare, the environment, and ethical implications
The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.
?Närmast i tiden är det ju blåssidan som gått ned.? : En studie om musiklärares och rektorers syn på barns instrumentval och kommunala musik- och kulturskolors rekryteringsmetoder
The purpose of this study is, on one hand, to obtain an understanding of how children in municipal music- and culture schools choose instruments and what forms of recruitment methods they are subjected to, and on the other hand, how you can make them continue to play once they have begun.To acquire this information, I have interviewed five music teachers and two principals at municipal music- and culture schools in Värmland. The questions treated, among other things, what affects children?s instrument preferences, recruitment methods and what you can do to keep interest for the chosen instrument alive.The result of the study shows some apparent tendencies. Even though some of the instruments have trouble recruiting students and other instruments have trouble keeping them, the old methods, which obviously do not work in a satisfactory manner, are still being used. Instead, increased commitment at the occasion of recruitment, more group teaching which strengthens the social bonds through role models and a will to have the courage to change the organization when it does not work, is required..
Forensic Carving from Unallocated Space
Computer Forensics investigations have become more and more common while
investigating IT-related issues. From experience, hard disks, USB thumb, memory
sticks contains information that might be useful. Computer Forensics is
regulary conducted by Police, Customs, Tax investigators but also within
private companies and organisations. However, there are areas within the
storage device that are not part of the organisied structure that a file system
gives. The reason for that might be that the information has been erased by
intention, a virus destroyed the file system and so on.
Studie av olika metoder för att mobilanpassa stora CMS webbplatser
The work has been performed in collaboration with Jönköping University. The aim of this work has been to study different methods for mobile adaption of large CMS (Content Management System) websites, where the website of Jönköping has been used as a reference.The website at Jönköping University is used daily by current students, faculties, prospective students and external users. Research carried out by the University shows that the use of mobile devices has increased, and it is therefore necessary to examine the mobile adaptation of the large CMS website.A layout proposal has been suggested by determining which method that is most relevant for mobile adaption of a large CMS website. The website should adapt to different resolutions and devices according to how the existing website is based in the current situation. Emphasis has been put on menu operations, to navigate through the large website in a user-friendly way.
Avblås för torkning av kabel
This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.
Ett på allvar integrerat svenskämne? : En studie av uppgiftskulturen i läromedlet Känslan för ord.
The aim of this paper is to analyze and problematize the content in the teaching media Känslan för ord through an integrative perspective. This is done by using two sets of questions based on two of the didactic questions what and how. How is the content of the Swedish subject constructed in Känslan för ord? and How is this content integrated in Känslan för ord? The used material consists of a fairly large amount of literature which provides different approaches, priorities, and methods about the Swedish subject. This literature forms the base for the model used to analyze the course books.The results are based on an analysis of the exercise culture (uppgiftskultur) in the two books and are extensive.
Det digitala teknikskiftets inverkan på pressfotografer : en undersökning av övergången till digital fototeknik på Bohusläningen
The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.
Naturlig nedbrytning av klorerade lösningsmedel i grundvatten
Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

Är priset ett sätt att påverka mängd frukt och grönsaker i kosten?
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Is pricing a way to affect share of fruits and vegetables in a diet?Author: Maria PopovSupervisor: Heléne Bertéus ForslundExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 23, 2013Background: Fruits and vegetables (FV) are important for health, including occurrence of diabetes, obesity and cardiovascular diseases. Said diseases cause most cases of illness and death in high-income countries. Only a small part of the population achieves the FV-intake goal, so a higher FV-intake is desirable. Besides general information campaigns there is another method of influencing what people might buy.Objective: To examine whether different pricing is connected to FV-intake or ?purchase.Search strategy: Databases PubMed, Scopus and Summon were searched with ?vegetable consumption", "price/pricing policy" and "food choice? in different combinations.Selection criteria: Studies performed after year 2000 on at least 18 years old persons from North America, Europe or Australia, examining changes in FV-price and -purchase.
Etisk organisationskulturs inverkan på revisionskvalitet i företag
In today's society there is tougher climate both financially and time wise. Accountants working under tight deadlines leading to the compromise between quality and quantity in the audit process and them therefor are being guilty of so-called reduced audit quality, RAQ. Reduced audit quality involves intentional actions designed to somehow reduce the evidence contained in the audit. We examine in this study the impact of time budget pressure (TBP), underreporting of time (URT), ethical organizational culture and charismatic leadership has on the frequency of RAQ.Previous research has already shown that there are clear links between TBP and RAQ, between URT and RAQ and between ethical culture in organizations and audit quality available. Five hypotheses were designed to the study.
