NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.
Minskande andelar kraftfoder i foderstaten under betesperioden : effekt på mjölkavkastning och betesbeteende hos mjölkkor
Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.
OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

EC Legal Regulation of the Insurance Market; Challenges of Integration
Over the last decade, the private insurance market has undergone a stable growth in turnover and growing demand for insurance products in all Member States of the European Union. Therefore, the creation of a single market in insurance will enable consumers to have access to wider choice of insurance products, and insurance companies to gain access to markets in various Member States and compete effectively.
The EU legal framework for the insurance industry embraces the Treaty freedoms of services, establishment and capital, the EC Directives and the ECJ case-law. The present thesis identifies numerous factors that hinder the Community insurance market integration and offers possible remedies. The summary of the market obstacles is all-inclusive and reflects the responses to the questionnaires and the Commission surveys.

Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Probiotika som prevention mot urogenitala sjukdomar
About 10 % of the adult women population in Sweden are treated annually for urinary tract infections. The increasing bacterial resistance towards antibiotics is classified by WHO (World Health Organization) and ECDC (European Centre for Disease Prevention and Control) as one of the greatest treats for human health in a global perspective. To find alternatives scientists are studying the possibility to use probiotics to reduce the frequency of recurring urinary tract infections. This literature study examines five randomized double blinded placebo controlled studies where different strains of Lactobacillus have been used as a prophylactic to women suffering from recurrent urinary tract infections and bacterial vaginosis. Overall the studies do not display enough promising results to recommend the use of probiotics as a prophylax or cure..
Möjligheterna för teknikkonsultföretag att bidra till positiv indirekt miljöpåverkan : En studie hur teknikkonsultföretag kan genomföra fler miljörelaterade uppdrag
As the environmental requirements on businesses increase from various stakeholders, the incentives for businesses to work more with environmental issues also increase. Historically, the requirements were focusing on companies with direct emissions from operations. Lately, the environmental impacts that occur indirectly as results of corporate activities have become more topical. Companies and organizations that mainly offer services often have a greater indirect than direct environmental impact. This is because they are affecting third parties, which in turn have a direct environmental impact.
