SammanfattningDenna studie ämnar till att bredda kunskap kring sexual debut i Rwanda, där forskning i en afrikansk kontext kopplar tidig ålder vid sexual debut samt föräktenskapligt sex till ett riskfyllt sexuellt beteende. Eftersom att risken för ökat antal sex partners samt oskyddat sex stiger, vilket kan leda till oönskade effekter så som sexuellt överförbara sjukdomar och oönskade graviditeter. Rwanda är ett land som drabbats hårt av HIV spridning framförallt som en konsekvens av oskyddat samlag. Därför anser vi att en studie kring sexuellt beteende är ett viktigt område att belysa. Uppsatsen avser att studera vilka faktorer som kan tänkas ha ett samband med ålder vid sexual debut, kontrollerat för om första samlaget skedde innan äktenskapet eller efter.

Chile and Santiago are struggling with heavy environmental problems as a consequence of Urbanisation and industrialisation. In the Santiago region the air is seriously contaminated and most of the rivers are classified as heavily polluted.The aim of this thesis is to survey the industrial fluid waste situation in the Santiago region and to make suggestions on technological improvements or process changes. The purpose is also to study five different enterprises more closely and to give more detailed suggestions for improvement. Another purpose is to summarize relevant Chilean legislation.Information, provided by the supervisory authority, about the release of industrial wastewater to rivers has been analysed. Deep interviews have been made with authorities and consultants.

The population growth and Urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.
