background : in recent years tissue engineering developed to replace or repair damaged tissues using cell and biomaterial. one of the most important fields of tissue engineering is simulation of in vivo micro environment of body tissues. this study aimed to develop culture chamber and cell biomaterial sheet engineering for the reconstruction of cartilage tissue. methods : stainless steel cultur...

introduction for dose measurement in megavoltage (mv) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. therefore, the result of measurement should be corrected with a displacement perturbation correction factor (pdis) or using an effective point of measurement (epom). the aim of this study is to calculate the epom for cylindrical ion chamber and...

The article below aims to analyze the feeling of thermal comfort model in real and simulated conditions. research survey were carried out on a group students lecture hall, “Energis” intelligent building, Kielce University Technology. respondents assessed impressions situation. In climate chamber, climatic room quality simulated. Particular attention was paid temperature humidity, which set at s...

introduction computed tomography scans are a very important tool for diagnosis and assessment of response to treatment in the practice of medicine. ionizing radiation in medical imaging is undoubtedly one of the most powerful diagnostic tools in medicine. yet, as with all medical interventions, there are potential risks in addition to the clear potential benefits. materials and methods two refe...

Branched glycerol dialkyl glycerol tetraethers (br GDGTs) are membrane lipids produced by unknown Bacteria and are being increasingly used as temperature proxies. Nevertheless, the direct effect of temperature on br GDGT distributions has been rarely evaluated. In this study, the impact of increasing temperature on brGDGT distributions and the speed of adaptation of br GDGT source microorganism...
