2. 21. Identification and validation of risk factors in cold work

   Author : Lina Giedraityte; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Work Environment; Industriell produktionsmiljö;

   Abstract : There are very few methods available for the assessment of cold exposure and they rely more or less on complex equations for calculating heat balance; therefore, there is a need for new practical methods for the identification and control of cold hazards in workplaces. In the first study, the aim was to test a checklist which enables cold risk assessment based on observations in the workplace. READ MORE

4. 22. Stability of ultra-high temperature treated milk : the effect of raw milk quality, storage temperature and storage time

   Author : Maria Karlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : The composition and properties of raw milk are important for the stability of dairy products, especially for products with long shelf-life, e.g. ultra-high temperature (UHT) treated milk. READ MORE

5. 23. Physiological and biochemical aspects of vegetable processing. A case study on carrots

   Author : Federico Gómez Galindo; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; mild blanching; antifreeze proteins; cell wall; cold acclimation; carrots; metabolism;

   Abstract : The aim of the present study was to enhance our understanding of vegetables as living organisms, interacting dynamically with the environment, and to explore the possible influence of metabolic changes on subsequent processing operations. Growing conditions, harvesting and handling in the packing house and storage conditions are key events leading to a defined “physiological status” of the vegetable that is going to be consumed as a fresh product or a processed product.

6. 24. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

   Author : Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

   Abstract : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.

7. 25. Plasticized Poly (lactic acid) Films - Preparation and Properties

   Author : Nadia Ljungberg; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phase separation; aging; thermal properties; dynamic mechanical properties; processing; film preparation; oligomer synthesis; poly lactic acid ; plasticizers; migration; cold crystallization; Polymer technology; biopolymers; Polymerteknik;

   Abstract : The development of biodegradable polymers from renewable resources is of importance in order to prevent the depletion of fossil fuels and the increasing emissions of carbon dioxide to the atmosphere caused by the commodity plastics of today. However, to be able to replace these non-environmentally friendly materials, production costs of biodegradable polymers have to be decreased and their physical properties need to be enhanced.
