  1. 21. Bacteriological Hygiene in the Production of Pasteurised Milk

    Författare :Åsa Eneroth; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; RAPD; Bacillus cereus; Pseudomonas; Gram-negative; recontamination source; spoilage flora; phychrotrophs; recontamination; dairy hygiene; pasteurised milk; Livsmedelsteknik;

    Sammanfattning : Critical contamination sites and sources for the Gram-negative psychrotrophs (GNP) of the taxa Pseudomonas, Enterobacteriaceae and Aeromonas, and the Gram-positive spore-forming (GPS) species Bacillus cereus, have been traced in the production line of pasteurised milk. Samples of raw and pasteurised milk from different sampling sites along the line were collected. LÄS MER

  3. 22. Subsurface Environmental Impact in Urban Areas. Shallow Groundwater Composition, Corrosion of Soil-Buried Constructions, and Leachates from Reclaimed Asphalt Pavement

    Författare :Malin Norin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GC MS screening; soil-buried constructions; subsurface urban environment; shallow groundwater quality; corrosion; reclaimed asphalt pavement;

    Sammanfattning : Worldwide, groundwater represents the largest and most important source of potable water. Usually, urbanisation affects shallow urban aquifers in two ways: by radically changing patterns and rates of aquifer recharge, and by adversely affecting the quality of groundwater. LÄS MER

  4. 23. On the Study of a Liquid Steel Sampling Process

    Författare :Zhi Zhang; Pär Jönsson; Anders Tilliander; Seppo Louhenkilppi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The liquid steel sampling method is one of the commonly used procedures in monitoring the steelmaking process. Besides it can be used for analyzing the dissolved alloys, hydrogen content and oxygen content, it can be also employed to monitor the inclusion characteristics at the steelmakings. LÄS MER

  5. 24. The origin of the marine Lockne impact structure, Jämtland

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lockne; Jämtland; Earth sciences; Geovetenskap; allmän och historisk geologi; General and Historical Geology;

    Sammanfattning : The Lockne impact structure in Jämtland (63o00'20"N, 14o49'30"E), formed in the Middle Ordovician at approximately 455 Ma. The structure is a concentric crater with a total diameter of 13.5 km. The impact took place in a marine environment. LÄS MER

  7. 25. COMBINED DEHYDRATION METHODS - From Fresh Fruit to High-quality Ingredients

    Författare :Frédéric Prothon; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; semi-finished products; agent; collapse; apple; microwave-assisted air-drying; dehydration; osmotic treatment;

    Sammanfattning : Numerous products from the food industry contain fruit and/or berries, in the form of fillings or ingredients, e. g. in yoghurt, some bread products/cereal products, ice cream, etc. In order to produce these ingredients and improve their characteristics, many processing techniques are available.
