This study aimed to investigate the effect of storage at ?3 °C on myofibrillar protein in fast or slow frozen pork. Five pork loins 48 h post-mortem were subjected either (cold metal plate/?80 °C) freezing (still air/?20 followed by for 0, 1, 3, and 7 days before thawing. Freezing rate significantly influenced proteins within 3 °C, evidenced higher thaw loss, surface hydrophobicity reduced wate...

background : in many jobs, individuals are exposed to thermal stress, and thus, evaluation of heat stress is necessary. this study was conducted with the purpose of investigating the relationship of perceptual strain index (pesi) with other heat indexes under hot laboratory conditions. methods: this empirical-experimental and cross-sectional study was performed in 5 different temperatures (21 º...

The land surface temperature obtained from remote sensing was widely used in the simulation of permafrost mapping instead air with rapid development technology. freezing and thawing index (LFI LTI), which is commonly regarded as ground (GFI GTI), can produce certain errors distribution on Qinghai–Tibet Plateau. This paper improved accuracy thermal condition soil Engineering Corridor (QTEC) by c...

The EU directives on air quality force member states to inform the public on the status of the ambient air quality. The Internet is commonly used for this purpose and often air quality is being presented as an index ranging from good to bad. A review of existing websites and air quality indices shows that the way air quality is interpreted differs considerably. The paper presents a new air qual...

A mathematical model, numerical algorithm and program code for simulation thermal changes in permafrost as a result of operation of a horizontal flare system in northern oil and gas field are presented. In the model the most significant climatic and physical factors are taken into account such as solar radiation, determined by specific geographical location, heterogeneous structure of frozen so...

The present study was to improve the success for the cryopreservation of stallion spermatozoa, especially as the costs of using low post-thaw motility or sub-optimal fertility deters owners and breeders from using frozen semen. The aim was to develop a freezing extender/process that supports cell survivability throughout the freezing. Eleven stallions were collected and frozen in INRA 96 with t...
