The aim of this study was to evaluate the effect of different thawing protocols (slow (P1), medium (P2), and fast (P3)) on percentage of motile sperm (MOT) and percentage of sperm cells with intact me...
Effects of aging and freezing/thawing sequence on quality attributes of bovine Mm. gluteus medius and biceps femoris
Aging Freezing Glutathione Peroxidase Purge Thawing
2017/3/9
The effects of aging and freezing/thawing sequence on color, physicochemical, and enzymatic characteristics of two beef muscles (Mm. gluteus medius, GM and biceps femoris, BF) were evaluated.
Effect of low-density lipoprotein addition to soybean lecithin-based extenders on bull spermatozoa following freezing-thawing–preliminary results
bull sperm cryopreservation sperm motility viability cryoprotectant
2016/12/20
Soybean lecithin-based extenders represent an alternative to extenders containing egg yolk, but there has been discussion about their cryoprotective efficacy. Low-density lipoprotein (LDL) was proved ...
Consumer Attitudes Toward Storing and Thawing Chicken and Effects of the Common Thawing Practices on Some Quality Characteristics of Frozen Chicken
Consumer Preference Poultry Chicken Freezing Thawing, Quality
2016/5/20
In this study, a survey was conducted to both evaluate the consumers’ general attitudes for purchasing and storing the raw chicken and determine the thawing practices used for defrosting frozen chicke...
UD prof studies how permafrost thawing affects vegetation,carbon cycle
UD prof permafrost thawing vegetation carbon cycle
2016/3/11
“There is a lot of carbon frozen in the Arctic soil’s permafrost layer. If this all thaws out, prevailing thought is that the carbon in the soil could be released to the atmosphere and potentially acc...
Effect of microwave thawing on microstructure and physicochemical stability of low fat white sauces made with soy protein
Confocal laser scanning microscopy (CLSM) microwave heating SDS-PAGE soy protein isolate starch
2014/2/24
The microstructural and physicochemical stability of white sauces made with soy protein and modified waxy maize starch was evaluated after subjecting them to a freezing-thawing process in a convention...
Colour Changes in Meat of Foals as Affected by Slaughtering Age and Post-thawing Time
Age at Slaughtering Foal Meat Meat Colour

The aim of the present work was to investigate how colour changes of foal meat can vary after thawing out in relation to the slaughtering age of the horses and to the post-thawing time. Eighteen Itali...
The effect of curvature in thawing models
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/29
We study the evolution of spatial curvature for thawing class of dark energy models. We examine the evolution of the equation of state parameter, $w_\phi$, as a function of the scale factor $a$, for t...

冻融循环对甲壳素凝聚态结构和脱乙酰反应的影响（Effects of Freezing-thawing Cyclic Treatment on Condensed State Structure and N-deacetylation of Chitin）
甲壳素 冻融循环处理 N-脱乙酰反应
2009/11/3
甲壳素和质量分数为40%的浓NaOH溶液的混合物在-18℃和40℃条件下反复进行冻融处理，结果表明慢速冷冻加低温解冻的冻融循环处理过程中，冰晶的反复形成和重结晶能够破坏甲壳素凝聚态特别是晶态结构。经过3次冻融循环处理，可使甲壳素在NaOH溶液中完全溶解，获得甲壳素最终质量分数为4%，NaOH最终质量分数约为10%的均相溶液，为用均相脱乙酰法制备半脱乙酰水溶性甲壳素提供前提。
