The economic consequences of Striga hermonthica in maize production in Western Kenya

Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.

Kvinnan:mannen::alternativet:normen ett feministiskt perspektiv på klassifikation

Using a feministic perspective and a critical approach, my purpose is to discuss bibliographic classification, a central aspect of Library and Information Science. More specifically, my aim is to demonstrate the norms and the dominating thoughts regarding the organization and representation of knowledge, subjects, and social categories in classification systems. I review previous research involving critical approaches to classification. These show that classification systems are a reflection of the context in which they are created, with the result that universal assumptions can be questioned. Some studies also present problems inherent in hierarchical structures.

ADHD och fetma hos vuxna personer : En litteraturstudie

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.

Sjuksköterskors uppfattningar ominformationssäkerhet : en kvalitativ intervjustudie

Inom hälso- och sjukvården hanteras känslig patientinformation. I framtiden kommer alltmer information att lagras elektroniskt och därmed bli mer lättillgänglig. Användarna av informationssystemen kan vara en säkerhetsrisk. Metoderna som används vid intrångsförsök inriktas alltmer på att involvera människor istället för att enbart använda sig av teknik.Syftet med detta arbete är att undersöka användarnas upplevelse och medvetenhet om icke tekniska hot mot informationssäkerheten för digitalt lagrad patientinformation.Datainsamlingen genomfördes i form av kvalitativa intervjuer med sjuksköterskor anställda på ett sjukhus i västra Sverige. Resultatet visar att det allt överskuggande upplevda hotet var intrång och förlust av sekretess i den elektroniska patientjournalen.

8263 kilometer: En studie i avståndets påverkan på styrsystem

The aim of this Master?s thesis is to study the effects that geographical distance have on the control systems in a scattered organization and how this, ultimately, affects the employees in terms of loyalty and motivation. In order to do this, a case study has been conducted on a multinational travel group and its local branches in Thailand. The study is based on a selected number of theories focusing mainly on control systems in multinational contexts as well as on theories regarding communication and autonomy. The conclusion of the study is that geographical distance has led to a rather large autonomy for the local branches and that the headquarter to a large extent rely more on formal control.

Tillförlitlighet hos information som hanteras av flera användare och genom flera system

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

Human Stem Cell - European National Innovation Systems and Patents

The purpose of this paper is for the reader to realise how national innovation systems are deeply intertwined with the legal background of a country and to understand the processes that involves national innovation systems specifically regarding the stem cell / genetics research and how the need for specific community law must be considered targeting the stem cell patents. The legal part will try to answer: Why is it important given the actual state of the European stem cell national innovation systems for the European Commission to take a stand and tackle issues regarding the patenting of the human stem cell innovations? This is done from a country industry analysis (business approach) and then linking it with competition law from a community stand point of view (that tackles biotechnology issues). In order to achieve this the paper is divided into three separate analyses beginning with a theoretical background of general biotechnology / genetic terms that will enable the reader to have a general understanding of the importance of this kind or research ( genetics / stem cell research). The chosen countries case studies exemplify very diverse economies and development perspective from the traditionally R&D intensive to the least and from the biggest countries in Europe to one of the smallest, thus giving cultural, legal, economic and scientific variety..

Kreativa föräldrar - En fallstudie om föräldraskapets och föräldraledighetens effekt på förälderns kreativitet i arbetet

Parenting and parental leave in a career context is a highly topical subject in which discussions about gender equality and corporate discrimination against parents occur daily. Media has recently raised the theory of parenting and parental leave as having positive impacts on personal development, such as creativity enhancement, which may promote the individual's work performance. Despite the subject's significant value for society and organizations, no scientific research is to be found. This paper examines how an individual's creativity at work is affected when becoming a parent and if parental leave has any contributory effect. Furthermore, the paper identifies and scrutinizes four creativity theories that may help explain these changes in creativity.

Utökade tillämpningsmöjligheter för turbinlösning i våtpartiet hos tissuemaskiner : Konceptförslag som möjliggör tillämpning av turbinlösning för maskiner vars banbredd är bredare än 2,9 meter

AbstractThis thesis is the final part of the Innovation and Design Engineering Programme (180 ECTS credits)at the Faculty of Health, Nature and Engineering Science at Karlstad University. The extent of thisthesis is 22.5 ECTS credits and has been performed independently by Hannes Jernberg during thespring of 2013. Metso Paper Karlstad AB is the task maker of this project, and Arvid Johansson is thecompany Representative. Metso Paper Karlstad AB is one of the world leading developer andmanufacturer of tissue paper machines.In the current situation, the company has developed and patented a power management systembased on a Cross Flow Turbine. The current construction is limited to a paper width of 2.9 meters.The company wants to take advantage of all the opportunities provided by the patents, to develop aturbine solution paper machine with a paper width that is wider than 5.5 meters, and give the abilityto manufacture paper for lower energy consumption which is an important part of the production asit is very energy intensive.Problems arise with the increasing length of the turbine, ultimately resulting in that the deflectionbecomes too big and that the momentums, due to the increased torque the turbine blades breaks.By applying the design process, this work has resulted in a number of potential solutions to theproblem.

Förutsättningskontroll och nedbrytningstest på oljeförorenad mark : Preem 2, Karlstad

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

The method used has been participant observation and was used to be able to comeclose to reality and thus find problem areas where there are opportunities for development.Validation was made through comments and opinions from workers at Grontmij AB, afterreading the reports analysis.Based on a system and holistic approach has parallels been drawn to the production systems suchas TPS (Toyota Production System) and lean production.

Vinstdelning: En studie i hur affärsjuridiska advokatbyråers vinstdelningssystem är uppbyggda och hur valet av vinstdelningssystem påverkar organisationen.

In the last couple of decades, corporate law firms have rapidly grown to become both influential and highly profitable corporations in the business world. Today, the largest law firms are assumed to bear far greater resemblance to large and often multinational public limited companies than the small businesses generally associated with legal services. However, one interesting specific set them apart from the majority of other companies; the partnership and its interrelated profit sharing. The aim of this study has therefore been to investigate partner compensation systems in corporate law firms and further examine what implications chosen compensation systems have on the organizations. Using a multiple case study, including 7 of Scandinavia?s largest and most well known law firms, the results show that partner compensation systems are highly individual and the critical question is whether to employ seniority based or performance based compensation systems.

Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem

This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.
