1. Chilling requirement of four peach cultivars estimated by changes in flower bud weights
ABSTRACT The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four di

2. Do climate changes alter the distribution and transmission of malaria? Evidence assessment and recommendations for future studies
Abstract Malaria, a mosquito-borne infectious disease, is considered a significant global health burden. Climate changes or different weather conditions may impact infectious diseases, specifically those transmitted by insect vectors and contaminated water. Based on the current predictions for climate change associated with the increase in carbon dioxide con

3. Climatic Response of Cedrela fissilis Radial Growth in the Ombrophilous Mixed Forest, Paraná, Brazil
ABSTRACT We examined the climatic response of Cedrela fissilis radial growth based on precipitation, air relative humidity, temperature and monthly thermal amplitude. It was intended to assess how the secondary growth of C. fissilis is influenced by the climatic variables and which one are the best growth predictors in Ombrophilous Mixed Forest, southern Bra

4. Trends in Crop Reference Evapotranspiration and Climatological Variables Across Ceará State – Brazil
Resumo A irrigação representa uma parte substancial na demanda de água mundial. Em âmbito global, a retirada para a agricultura é de 69%. A irrigação é necessária para compensar o déficit em evapotranspiração (ET) devido à precipitação insuficiente. O conhecimento dos impactos das mudanças climáticas em variáveis meteorológicas que afetam

5. Using climate change models to assess the probability of weather extremes events: a local scale study based on the generalized extreme value distribution
ABSTRACT Regional climate models (e.g. Eta) nested to global climate models (e.g. HadGEM2-ES and MIROC5) have been used to assess potential impacts of climate change at regional scales. This study used the generalized extreme value distribution (GEV) to evaluate the ability of two nested models (Eta-HadGEM2-ES and Eta-MIROC5) to assess the probability of dai

6. Influence of tribological test on the global conversion of natural composites
Abstract The vinyl ester resins and natural composites have emerged as a suitable alternative in tribological application due to mechanical behavior, which relates to the conversion of the double bonds. During tribological test the permanent contact between polymeric sample and counterpart can increase the temperature affecting the crosslinking of the sample

7. Energy consumption reduction strategy for freezing of packaged food products
Abstract In this work, a model of the process of freezing strawberries placed in boxes using forced air tunnel was studied. A strategy of operating condition modification in each stage of the process (pre-cooling, freezing step and sub-cooling) was applied, in a simulated process, regarding air temperature change. Time and energy consumption behaviors due to

8. Population dynamics of Siderastrea stellata Verrill, 1868 from Rocas Atoll, RN: implications for predicted climate change impacts at the only South Atlantic atoll
ABSTRACT Coral reefs are one of the most vulnerable ecosystems to ocean warming and acidification, and it is important to determine the role of reef building species in this environment in order to obtain insight into their susceptibility to expected impacts of global changes. Aspects of the life history of a coral population, such as reproduction, growth an

9. Agriculture and food security challenge of climate change: a dynamic analysis for policy selection
ABSTRACT This study presents an empirical examination of climate change related to vulnerability impacts on food security and remedial adaptation options as a suitable strategy by prioritizing needs over a 50-year period. An Empirical Dynamic Commutable General Equilibrium Model for Climate and the Economy (EDCGECE) is applied using future strategies for Mal

10. Contaminación del aire en la Ciudad Autónoma de Buenos Aires: el riesgo de hoy o el cambio climático futuro, una falsa opción
Based on the theoretical framework of environmental risk, this article discusses the management of air quality in the Autonomous City of Buenos Aires in relation to current and potential impacts of toxic gases and global climate change on the health of the population. Information on historical and current management of the air was linked to the results of th

11. Hormonal changes in female buffaloes under shading in tropical climate of Eastern Amazon, Brazil
The hormonal responses of 20 female buffaloes raised under the sun (SS group) or in the shade (CS group) in Belém, Pará, Brazil, were assessed. The CS group (n = 10) was kept in a silvopasture system featuring Racosperma mangium, whereas the SS group (n = 10) was kept in paddocks without shade featuring Brachiaria humidicola, drinking water, and mineral sa

12. Um problema de interação oceano-atmosfera-biosfera: alterações potenciais na vegetação da América do Sul devidas ao aquecimento global
One of the expected consequences of global warming is change in the distribution and structure of vegetation. Few studies have evaluated the dynamic behavior of tropical vegetation against a backdrop of elevated CO2, with mixed results for the vegetation in South America. One possibility to explain the opposite results are different patterns of sea surface t
