1. Cold stress reduces rice grain yield in temperate conditions
RESUMO O arroz é originário de climas tropicais e, quando cultivado em regiões temperadas, pode ter sua produtividade reduzida por exposição ao estresse por frio. Este estudo buscou avaliar as perdas produtivas associadas ao frio em diversas variedades de arroz e a tomada de decisão pela resemeadura da lavoura. A semeadura foi realizada em época preco

2. Effect of ethanol Adiantum capillus-veneris extract in experimental models of anxiety and depression
Depression is one of the most common psychiatric disorders with a prevalence of 15%-25%. Monoamine aminotransferases, in particular, norepinephrine, serotonin, and dopamine, change in the brain of depressed people. Adiantum capillus-veneris is one of the species of the maidenhair fern genus that have traditionally been used to treat cough, cold symptoms, and

3. Ammopiptanthus mongolicus stress-responsive NAC gene enhances the tolerance of transgenic Arabidopsis thaliana to drought and cold stresses
Abstract Drought and cold are the primary factors limiting plant growth worldwide. The Ammopiptanthus mongolicus NAC11 (AmNAC11) gene encodes a stress-responsive transcription factor. Expression of the AmNAC11 gene was induced by drought, cold and high salinity. The AmNAC11 protein was localized in the nucleus and plays an important role in tolerance to drou

4. Determination of phases and residual stresses after martensitic transformation induced by rolling in 304L stainless steel
RESUMO O aço inoxidável austenítico 304L é suscetível à transformação martensítica induzida por deformação. Esta transformação de fases depende da temperatura, assim como do modo, taxa e nível de deformação. Neste trabalho as fases e tensões residuais de um aço TRIP 304L, em que a transformação martensítica foi induzida por laminação a

5. Comparative Analysis of C-repeat Binding Factors (CBFs) in Tomato and Arabidopsis
Abstract Cold stress is one of the limiting factors of plant production that plants use different mechanisms for cold tolerance. CBF genes play critical role to regulate the cold responsive genes. To better understand of CBF gene functions, the tomato-CBFs and Arabidopsis-CBFs were evaluated using bioinformatics tools, and finally the expression patterns of

6. Effect of cold-working process on cyclic deformation of electrolytic copper
Abstract Cyclic softening and hardening processes are expressed by the change in the stress amplitude necessary to cause a given strain amplitude. Understanding the cyclic stress-strain behavior of materials is an important step in the complex study of their fatigue behavior. The potential differences between the defect structures of cold-formed materials ma

7. Effect of vaporized perfluorocarbon on oxidative stress during the cold ischemia phase of lung graft preservation
RESUMO O perfluorocarbono (PFC) líquido tem sido estudado experimentalmente como uma substância adjuvante na preservação de enxertos pulmonares durante o período de isquemia fria. O objetivo deste estudo foi avaliar se o PFC vaporizado (e não instilado) também atuaria como protetor de enxertos pulmonares em diferentes tempos de isquemia fria. Realizam

8. INFLUENCE OF DIFFERENT THERMAL ENVIRONMENTS ON THE PERFORMANCE OF LAYING HENS DURING THE INITIAL STAGE OF REARING
ABSTRACT This study was conducted with the aim of assessing the effects of different ambient temperature values on the performance of laying birds from one to 42 days of age in order to obtain optimal comfort temperatures. A total of 864 laying hens were distributed in four climatic chambers with different temperature ranges. One of the chambers was maintain

9. Mechanical characterization of PM aluminum composites by small punch test
ABSTRACT In this work Small Punch Test (SPT) was applied to study the mechanical behavior of ultrafine-grained Al-Al2O3metal matrix composites (MMCs) fabricated in situ via powder metallurgy route (HITEMAL®). Such MMCs show attractive mechanical properties, enhanced creep performance and increased thermal stability at elevated temperatures, not normally ass

10. Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm ischemia (group 1), cold ischemia (group 2), RIPC followed

11. Transcriptome sequencing analysis of alfalfa reveals CBF genes potentially playing important roles in response to freezing stress
Abstract Alfalfa (Medicago sativa L.) is an important perennial forage, with high nutritional value, which is widely grown in the world. Because of low freezing tolerance, its distribution and production are threatened and limited by winter weather. To understand the complex regulation mechanisms of freezing tolerance in alfalfa, we performed transcriptome s

12. Microstructure, Texture and Microhardness Evolution during Annealing Heat Treatment and Mechanical Behavior of the Niobium-Stabilized Ferritic Stainless Steel ASTM 430 and Niobium-Titanium-Stabilized Ferritic Stainless Steel ASTM 439: a Comparative Study
A comparison of the influence of microstructure and texture on mechanical behavior between the niobium-stabilized ferritic stainless steel type ASTM 430, 430Nb, and the niobium-titanium-stabilized ferritic stainless steel type ASTM 439 was performed. The two steels were supplied as cold rolled thin sheets and the annealing was interrupted in different tempe
