  2. 2. Damage mechanisms for near-infrared radiation induced cataract

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Zhaohua Yu; Uppsala universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; infrared radiation; photochemical; thermal; forward light scattering; lens; cataract; temperature; Arrhenius equation; heat diffusion;

    Abstract : Purpose: 1) To estimate the threshold dose and the time evolution for cataract induction by near infrared radiation (IRR) in seconds exposure time domain; 2) to determine the ocular temperature development during the threshold exposure; 3) to investigate if near IRR induces cumulative lens damage considering irradiance exposure time reciprocity; 4) to experimentally estimate the temperature in the lens indirectly from the measurement of temperature-induced light scattering increase.Methods: Before exposure, 6-weeks-old albino rats were anesthetized and the pupils of both eyes were dilated.

    Abstract : Popular Abstract in Swedish Värmestrålning är högst relevant i förbränningsmiljöer. I dessa miljöer är förbränningsgaser och partiklar den huvudsakliga källan till värmestrålning. Förbränningsmiljön är komplex att beskriva. READ MORE

  4. 4. Thermal stresses in load-bearing glass-timber components

    University dissertation from Växjö : School of Engineering, Linnaeus University

    Author : Karin Lundstedt; Linnéuniversitetet.; [2012]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermal stresses; thermal failure; glass and wood construction; incident solar radiation; shading; cracks; temperature difference; finite element method.; Technology byts ev till Engineering ; Teknik;

    Abstract : Thermal stresses can arise in glass used in architectonic realisations in buildings as a result of solar irradiation:  that is, sunlight.  The magnitude of these thermal stresses depends on the temperature conditions in the glass in terms of the temperature differences between warm and cold areas.

    Abstract : Ökat intresse för energiförbrukning och samtidiga krav på godtagbar termisk miljö gör det nödvändigt att i förväg kunna bedöma personpåverkan från olika kombinationer av klimatfaktorer. Enbart temperaturmätningar tar inte hänsyn till alla klimateffekter på en människa och speciellt inte för lokala effekter av luftrörelser och strålning. READ MORE
