in this study, accumulation of h2o2, malondialdehyde (mda) (as cold-induced oxidative stress indicators), the transcript levels of dehydrin and beta-glucosidase genes (involved in metabolic responses) was evaluated in chickpea cv. jam, using qrt-pcr during control, cold acclimation (ca), cold stress (cs), recovery, and freezing phases. results showed the existence of wide range of genetic capac...

Changes in membrane lipid composition play important roles in plant adaptation to and survival after freezing. Plant response to cold and freezing involves three distinct phases: cold acclimation, freezing, and post-freezing recovery. Considerable progress has been made toward understanding lipid changes during cold acclimation and freezing, but little is known about lipid alteration during pos...

The main goal of the study is to test the applicability of Infrared Thermography for verification of Thermal Boundary Conditions at external non-isothermal walls bounding the flow domain. Experimental and numerical studies have been made for transient and steady natural convection in a differentially heated cube filled with water. The analysis is carried out for pure convection of water in the ...

Ovarian tissue freezing or cryopreservation might be the only acceptable method for preserving the young women fertility, before radiotherapy or chemotherapy. This technology might be used for patients with recurrent ovarian cysts or endometriosis, without ovarian stimulation. Many efforts have made to improve cryopreservation conditions that should be seriously considered for cancer patients. ...

Classical to quantum decoherence transition, an issue existing for incoherent superposition of Bell-diagonal states is studied for three dimensional bipartite AB mixed quantum systems. Depending on the initial conditions, the dynamics of classical and quantum correlations can exhibit a sudden transition between classical to quantum decoherence. This result is calculated numerically by using ent...

BACKGROUND We aimed to evaluate different copro-preservation conditions along the duration of one month for a better outcome of molecular diagnosis of Cryptosporidium species. METHODS Ten samples out of 380 fresh stool samples collected from patients with diarrhea proved positive after direct examination, concentration, staining and confirmed by immunochromatographic test. The study was condu...

Italian wall lizards (Podarcis sicula campestris) were introduced to Long Island, New York, in 1967 and have subsequently spread through many urban and suburban communities. Their ability to spread further may be limited by their ability to tolerate the relatively cold winters of New York. We found that these lizards were able to survive cold temperatures by supercooling if they were kept dry. ...

Non-freezing cold injury (NFCI) is the Cinderella of thermal injuries and is a clinical syndrome that occurs when tissues are exposed to cold temperatures close to freezing point for sustained periods. NFCI is insidious in onset, often difficult to recognize and problematic to treat, and yet the condition accounts for significant morbidity in both military and civilians who work in cold conditi...

In an era of continued economic development around the globe, numerous rock-related projects including mining and gas/oil exploration are undertaken in regions with cold climates. Winters in the Iranian western and northwestern provinces are characterized by a high precipitation rate and a cold weather. Under such conditions, rocks are exposed to long freezing periods and several freeze-thaw (F...

As a test of the hypothesis that REM sleep deprivation reduces fear, the freezing behavior of 60 rats was measured under the conditions of the Bolles-Collier (1976) paradigm. These animals were first exposed to one of three treatments for 4 day s: a dry-environment control, a wetenvironment control, or a 4-day REM deprivation period. Next, the animals were fear conditioned in a square-box and t...
