1. DEVELOPMENT OF A LOW-COST OPEN-SOURCE PLATFORM CONNECTED TO THE INTERNET FOR ACQUISITION OF ENVIRONMENTAL PARAMETERS AND SOIL MOISTURE
ABSTRACT The development of the Internet and the technologies associated with it has allowed disseminating and cheapening of communication equipment, prototyping services, electronic sensors, and all types of devices. Agriculture has benefited from these technological advances to boost its productivity and profitability. This study presents the development o

2. Synthesis of 1,2,3-Triazole Benzophenone Derivatives and Evaluation of in vitro Sun Protection, Antioxidant Properties, and Antiproliferative Activity on HT-144 Melanoma Cells
Benzophenones display several biological activities, including antioxidant, anticancer, and photoprotective. Furthermore, antioxidants can minimize both ultraviolet absorption and tumor development. In the present investigation, a series of twenty-six 1,2,3-triazole-benzophenone derivatives were synthesized and had their antioxidant, anticancer, and photopro

3. Evaluation of Global Heating Reduction Potential with the Replacement of Electricity Supplied by the Local Concessionaire Via Solar Renewable Source.
Abstract The objective of this paper is to evaluate, through the 100-year Life Cycle Analysis, Global Warming Potential (GWP) and Global Temperature Increasing Potential (GTP) impact categories. It is proposed scenario of replacement of the energy matrix for the supply of electricity by Solar Photovoltaic, adopting as consumption base the facilities of Supe

4. Trellis systems, rootstocks and season influence on the phenolic composition of ‘Chenin Blanc’ grape
ABSTRACT: The biosynthesis of phenolic compounds might be influenced by environmental factors, such as solar radiation, temperature and relative air humidity, and production system. Some components of the production system, particularly the trellis system and rootstock, might change the phenolic composition of grapes due to microclimate of the cultivation re

5. Life cycle analysis of HCNG light-duty vehicle demonstration project
ABSTRACT The demonstration is an effective initiative to bridge the gap between a premature technology and its large-scale commercialization. A systematic method of LCA was used to perform the well-to-wheel analysis of a CNG light-duty truck operated with 0%, 15%, and 30% blends of hydrogen with compressed natural gas fuel under the system boundary of “per

6. SOLAR RADIATION USE EFFICIENCY AND GROSS PROTEIN OF SORGHUM FORAGE ARE MODIFIED BY THE CUTTING MANAGEMENT
Resumo O objetivo deste trabalho foi determinar o crescimento, a eficiência do uso da radiação solar e a proteína bruta do sorgo forrageiro submetido a diferentes manejos de cortes. Foi utilizado um esquema unifatorial em delineamento de blocos casualizados (manejo de cortes), que variou do tratamento sem corte até quatro cortes. O primeiro corte ocorre

7. Analysis of the Insertion of Particular Photovoltaic Generation in the Low Voltage Installations, Under the Approach to Performance, Safety, Maintenance and Operation of the PVS
ABSTRACT The growing use of Photovoltaic Solar Energy in Brazil, both in power plants and in distributed generation systems, brings with it a series of practical and technical questions that are not limited to the design and project of the systems. Environmental factors and resources related to the use, operation, maintenance, decommissioning and final dispo

8. Body orientation for thermoregulation and daily activity cycle of Mabuya macrorhyncha (Squamata: Scincidae)
ABSTRACT We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cyc

9. Obtaining an Optical Trap Type Surface by Plasma Electrolytic Oxidation
High performance solar collectors are those with high selectivity surfaces, high solar radiation absorption and that do not thermally reemit to the external environment. Strategies to enhance this performance might involve surface porosity modification. In this work, a plasma treatment technique called plasma electrolytic oxidation (PEO) has been tested to p

10. Sensitivity of the sorghum yield to individual changes in climate parameters: modelling based approach
Based on sensitivity analyses the effect of changing in climate on sorghum has been investigated. This has been achieved by conducting crop modeling experiments carried out with weather observations and output of global climate models. As can be anticipated results demonstrated that the sorghum yield is more sensitive to rainfall, solar radiation and CO2 con

11. Strawberry yield efficiency and its correlation with temperature and solar radiation
The impact that future climatic conditions will have on agricultural productivity depends on the sensitivity to each environmental factor and relative changes in temperature, precipitation and UV-B radiation. The strawberry (Fragaria x ananassa) is a microclimatic crop cultivated almost worldwide and Spain is the world's second-largest strawberry producer af

12. Variabilidade climática e correlação entre TSM e vazão fluvial nos rios Amazonas e Negro / Climate variability of the Atlantic and Pacific oceans and flow of the rivers Amazonas and Negro
Climate variability is a complex system generated by the participation of various actors and their role in atmospheric dynamics, the Sea Surface Temperature(SST) plays a key role in influencing the several features of the climate indexes: Southern Hemisphere Cancel Index Mode (SAM), Southern Oscillation Index (SOI), El Nino / Southern Oscillation (ENSO), (TN
