The purpose of this thesis is to test whether the theories of reciprocal altruism, nepotism due to kin selection and costly signaling can explain patterns of human altruism. A new way of investigating this has surfaced since the introduction of mobile phone money transfers in areas where social sharing is frequently exercised. Data was collected from 167 respondents in Nairobi, Kenya on their late

In the laminator there are three laminator stations where protective layers are applied to the paperboard. In each station there are several rollers which help perform the lamination process, the most important rollers to be considered in this thesis are the nip roller and the chill roller. The nip roller is pushed towards the chill roller using hydraulic cylinders , thus creating a narrow contact

This thesis aims to aid the consultancy Living Institute in evaluating the perceived effects of the cross‐cultural training courses it provides to a wide variety of clients. To do this we study the company in relationship to its clients, mapping out its theoretical foundation as well as its strategies for teaching culture. In order to gain a deeper understanding of what the company teaches and how

Det är tonfallet i texten och den stiliserade formen som gör att hundboken "The Dog Owner’s Manual" verkar både roligare och trendigare än en vanlig hundbok. Genom att framställa hunden som en produkt, använda ett tilltal som liknar det i en teknisk manual och göra illustrationerna stiliserade har boken fått en ironisk prägel som känns unik. Med den här uppsatsen har jag velat klargöra v

The last part of the product design process is called embodiment design, it aims to give a “physical body” to the product so as to make it ready to use. It is on that particular part of the design activity that I was working, I was included in the research for the embodiment design team of the machine design division in LTH. The main research work was upon the process of this phase, to try to unde

This Master Thesis treats the problems involved with a dust explosion inside a filter unit. The project is a cooperation between AB Ph. Nederman in Helsingborg and the Mechanical Design Department of Design Sciences LTH, Lund. The Master thesis was carried out from December 2009 to April 2010. The initial phase of the project involves studies of the phenomena dust explosions, standards and regulat

Objective: To redesign the current assembly process of the Ektorp Sofa from IKEA in order to improve cycle times, quality levels and to reduce, if possible, costs associated with manufacturing, production times and materials. IKEA wants to increase either the productivity or the quality standard of the Ektorp Sofa by simplifying the processes involved in the construc-tion of the sofa and modernizi

Fouling of direct steam injectors and holding cells is a serious problem in the heat treatment of products in the dairy industry. The fouling limits the run time of a plant and increases the time for cleaning. Both these factors will increase the processing cost. Four different direct steam injectors are tested and evaluated using the criteria fouling of the injector, the stability of the injector

This thesis provides insight into Global Care Chains located between Italy and Ukraine. The countries under analysis represent different ends of the Global Care Chain, Italy being a country of immense immigration and Ukraine being on the other side as a country of large emigration. The women who migrate are mostly mothers and/or wives and their most common employment is in the reproductive sector

The final purpose of this project is to create a platform that leads to the improvement of the braking feeling by the users of heavy vehicles. The complexity of the problem lays on the different constraints: geometrical and functional, and as well on the interaction with a human operator. The task is to design a new electronic brake pedal, with the possibility to change the relationship between fo

This report is part of the Master thesis performed by Markus Jonasson and Alexander Mann at the Department of Design Sciences at Lund University. Markus and Alexan-der have studied to become Masters of Science in Mechanical Engineering with In-dustrial Design. Per Liljeqvist, senior lecturer in Industrial Design at the Department of Design Sciences is instructor. Robert Bjärnemo, professor in Mach

The aim of the project is to retrofit a 3-axis CNC milling machine from the late 80’s with a 5-axis head, a new controller, reducing the noise and the vibrations produced by the machine to achieve a healthy work and educational environment. At the same time, the purpose is to study the CNC milling machine within the marc of European Directives and Standards to improve the security features and ens

This paper tries to connect economic development and total fertility rate together and used two VAR model with the optimal lag respectively to analyze the impacts of economic conditions on total fertility rate in Denmark within half a century from 1956 to 2008. From the regression result of the first model VAR (4), there are slight difference in the impacts caused by GDP per capita, consumer price

In this article, I estimated the impacts of American economy on Swedish economy from long-term perspective with using the standard form vector autoregression model (VAR model). In order to obtain a comprehensive point of view, I decided to investigate the relationship between these two countries from three aspects, living and working environment, export and import volumes and stock market. After g

This Master Thesis has been carried out for Dresser Wayne AB in Malmö, done at the Division of Machine Design, Department of Design Science at LTH, Lund’s Univer-sity. Dresser Wayne was interested in finding a new or improved flowmeter for their fuel-dispensers since the two current flowmeters were either expensive or having drift problems. Dresser Wayne also had their own idea of replacing the pi

This master thesis follows the process of a product design and development project concerning the mechanical design of an ultrasound sensor. The project giver is the global medical technology company Gambro specialized in products for dialysis. The mentioned ultrasound sensor is a level detector from Gambro’s hemodialysis ma-chines, designed to prevent the occurrence of air embolism. Air that for

Genom Europakonventionen och regeringsformen tillförsäkras den enskilde ett flertal rättigheter. Varje medborgare åtnjuter bland annat skydd till frihet och personlig säkerhet samt till privat och familjeliv, sitt hem och sin korrespondens. Dessa friheter får begränsas genom lag under förutsättning att begränsningen tillgodoser ändamål som är godtagbara i ett demokratiskt samhälle. Att utreda brotThe Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR) and the Swedish constitution guarantee everyone a number of civil rights. Every citizen has the right to respect for his private and family life, his home and his correspondence. These rights may be limited by law, presumed that these limitations have a righteous purpose in a democratic society. Investigating crimes

Vid genomgång av tidigare forskning visar det sig att det finns kunskapsluckor att fylla på området sustainable marketing communication inom modeindustrin. Syftet med uppsatsen är därför att undersöka hur modeföretag inriktat på masskonsumtion kommunicerar ut hållbarhet på ett trovärdigt sätt. Uppsatsen avser att belysa den intressekonflikt som kan råda mellan uppmuntrande av ständiga återköp och

Vietnam has experienced massive poverty reduction and rapid economic growth, following the effects of “the Doi Moi”, initiated in the late 1980’s. One of the growth sectors in this dramatic development is the ICT industry, which Danida has supported in various manners, amongst others through the Business-to-business (B2B) programme. The way inwhich it contributes to the ICT industry’s development
