Thirty-two compounds, including alcohols, ketones, aldehydes, esters, terpenoids, carboxylic acids, etc. were identified. The analysis revealed that the diurnal rhythm of release of volatile compounds from maple differed in July and in August. In July, the releasing of most volatile compounds reached the peak at 14 o'clock, when in August, the emission of volatile compounds reached the peak at 10 o'clock. Besides diurnal rhythm, there also existed other differences in the releasing of volatiles and their relative contents in July and in August. A possible explanation for this phenomenon is the maturation of leaves, since the sampling conditions were the same both in July and August. At the same time, the response of Anoplophora glabrpennis Motschulsky to volatiles was examined with field bioassay with traps. cis-3-hexen-1-ol was found to be more effective to attract A. glabrpennis than other volatiles released by ash-leaf maple tree in field trapping test. A mixture of 1-butanol, 1-pentanol and 2-pentanol was tested to be the most attractive to A. glabripennis among all tested volatiles. More field trapping tests should be conducted.展开更多

In the present work, surface diurnal warming strength in the East China Sea was calculated by the sea surface temperature(SST) data derived from the MODIS sensors carried by the satellites Aqua and Terra. Due to transit time difference, both the number of valid data and the surface diurnal warming strength computed by the MODIS-Aqua data are relatively larger than Terra. Therefore, the 10-year MODIS-Aqua data from 2005 to 2014 were used to analyze the monthly variability of the surface diurnal warming. Generally, the surface diurnal warming in the East China sea is stronger in summer and autumn but weaker in winter and spring, while it shows different peaks in different regions. Large events with ΔT≥5 K have also been discussed. They were found mainly in coastal area, especially near the Changjiang(Yangtze) River estuary. And there exists a high-incidence period from April to July. Furthermore, the relationship between surface diurnal warming and wind speed was discussed. Larger diurnal warming mainly lies in areas with low wind speed. And its possibility decreases with the increase of wind speed. Events with ΔT ≥2.5 K rarely occur when wind speed is over 12 m/s. Study on surface diurnal warming in the East China Sea may help to understand the daily scale air-sea interaction in the shelf seas. A potential application might be in the marine weather forecasts by numerical models. Its impact on the coastal eco-system and the activities of marine organisms can also be pursued.展开更多

In addition, sea surface temperatures （SSTs） over equatorial Pacific Ocean were integrated in the analysis. The association between each of the meteorological-biometeorological parameters and clinical-reported malaria cases was examined by using Poisson distribution and log as link function between the two categories of dataset. The next step was the building of a model by using Poisson multiple regression models （GLMs） in order to know the weather variables that lead to statistically changes in clinical-reported malaria cases. The study revealed that an increase of I m.s1 of wind speed can lead to an increase of about 164% and 171% in the monthly occurrence of malaria at 95% confidence interval in derived savanna and humid forest zone respectively. Also, an increase of I ℃ in air temperature and sea surface temperature is associated with 53.4% and 29% increase in monthly malaria occurrence （CI： 95%） in derived savanna while an increase of 1 ℃ in air temperature and sea surface temperature is associated with 56.4% and 15.4% increase in monthly malaria occurrence at 95% confidence interval in humid forest zone of Ondo State展开更多

I intend to raise a few questions that will help us to understand the role of this competition in the Portuguese musical and cultural scene of the 1960s. RTP Song Contest is the longest television song contest in Portugal. This competition went through several crucial moments in the recent history of Portugal, witnessing the change from dictatorship to democracy. In late 1960s, still under the authoritarian regime, several social changes took place and music played an important role in these changes, as several studies have documented. In 1969, Portugal bet on Simone de Oliveira to bring us the prize, but the result was not the expected. This event brought us many questions about the importance of the Portuguese participation in the Eurovision Song Contest and the faimess of the European evaluation. This paper intends to reflect the implications of this particular event and the importance of the Contest for the Portuguese music scene at the end of the critical 1960＇s. With this paper, I intend to introduce some lines of analysis of the first ten years of the Portuguese Radio and Television Song Contest （Festival RTP da Cang6o--RTP Song Contest）. I intend to raise a few questions that will help us to understand the role of this competition in the Portuguese musical and cultural scene of the late 1960s and 1970s, based on the study of the daily press. RTP Song Contest is the most long-life television contest in Portugal. For this reason, it is important to make a short historical overview of this period and the history of television in Portugal. At the same time, the analysis of statistical data of audiences enables us to understand the television phenomenon in the late 1960s.展开更多

Despite this high density, the production of dates is still insufficient even for the local consumption, this is due to： Increasing salinity of water and soil in the old palm groves, the spread of many fungal diseases, where the most serious is the Bayoud （Fusaruim oxysporum）, and finally insect pests, three of them remain the most serious： white scale locally named Semm （Parlatoria blanehardi）, Boufaroua （Oligonyehus afrasiaticus）, and Doud called dates worm （Ectomyelois ceratoniae）. By using different trapping techniques, an entomofauna inventory was realized in the region of Saoura, where 3238 individuals are collected, distributed in 13 orders, 72 families and more than 132 species. The inventory will allow us to classify insects according to their economic importance, determine their life cycle and know their adaptation to date palm. The dynamics of these populations will be studied through the spatial-temporal repartitions. In parallel this study aims to identify the natural enemies （auxiliaries and parasitoids） of date palm pests in order to improve the biological control and this in hopes to ameliorate the production.展开更多

In this dilemma, it appears that the oil communities are powerless in the face of the obnoxious display of might and the right to make and apply policies that affect the general well-being of the Niger Delta people and their environment. The question that might arise in this situation is the ethical perception of some of those who make and execute policies about the ecological problems of the region. Therefore, this paper focuses on discussing eco-justice in the light of Jesus teaching on equity and equality in Matt. 7.12, where he counsels that human actions on the others should be moderated by the actors＇ desire for his well-being.展开更多
