Effects of Tapping and Stimulation Frequency on Performance of Yield and Selected Latex Physiological Parameters of Rubber (Hevea Brasiliensis Muell.Arg.) Clones RRIM 600 and Gt 1
Three experiments were conducted on two rubber
clones to study the effects of tapping and stimulation
frequency on performance of yield and some selected
latex physiological parameters. The first experiment
studied the long-term effects of various frequencies of
2.5% ethephon stimulation on yield performance of RRIM
60 0 over 14 years duration. The second experiment
investigated the various combinations of tapping and
stimulation frequency on the yield performance of GT 1. over 14 years duration. A short-term experiment of four
years constituted the third experiment which studied the
effects of tapping and stimulation frequency on
performance of yield, some selected latex physiological
parameters and bark characteristics of RRIM 600
REGARDS CROISÉS DU MÉCANISME DE TOURS DE PAROLE DANS LES DISCUSSIONS ENDOLINGUES ET EXOLINGUES EN FRANÇAIS
International audienceThe management of turn-taking's strategies are not always identical from one language-culture system to another. In the intercultural conversation, this feature from the speaking turn causes difficulties for non-native, and it is possible that forces them to adapt to the native's behavior for " succeeding " the conversation

Sensitivity analysis of cotton trade liberalization: a global simulation model approach
Despite global efforts to reduce international trade barriers in order to enhance trade liberalization and establish a more fair competition environment with generally accepted standards, agricultural trade is still regarded as a distorted area, where subsidies are particularly abused by some countries with an aim to create unfair advantage for their goods in the world market. The cotton sector is one of the typical examples for the abuse of subsidies in international trade by titling the playing arena against developing countries. This thesis seeks to study the impact of cotton trade liberalization (i.e. removal of all tariffs and subsidies) and analyze the sensitivity of the Armington elasticities; in particular how escalating these elasticities may affect the results. This analysis is undertaken by developing a partial equilibrium model similar to the Global Simulation model (’GSIM’) designed by Francois and Hall (2003). The results show that the world prices increase evenly with the level of trade liberalization. The complete removal of tariffs and subsidies would increase the world cotton price by 7.13 per-cents. If the world price is lifted, non-subsidizing countries increase their production while the subsidizing countries decrease the same. The research once again confirms that huge losses that non-subsidizing countries suffer due to subsidies will become attained gains for these countries when such subsidies were eliminated. In addition, escalating the maximum value of elasticities of substitution will lead to smaller impacts on world prices (6.82 per-cent change in world price), but larger impacts on quantity (23.05 per-cent change in quantity).
Furthermore, the sensitivity analysis performed in this thesis showed no evidence that the Armington elasticities have a significant impact on the results
Optimizing Transportation Sequence in Warehouse with Genetic Algorithms
International audienceOptimizing transportation sequence is crucial to reduce material handling costs in warehouse operations and thus in total logistics costs. Transportation sequence is the ordering of storage and retrieval jobs that a material handling device has to perform to finish an order list. In many studies, the optimization of transportation sequence has been simplified as an order-picking problem, and accordingly solved as a classical traveling salesman problem. However, transportation sequence is a double-cycle storage and retrieval problem (DCSRP) in itself, meaning that the combination of storage and retrieval jobs into double cycles has to be considered simultaneously. In this paper, we propose formulating the DCSRP as a permutation problem and applying several genetic algorithms to solve the formulated problem. Extensive computational experiments were performed to demonstrate the capability of the approach. The experimental analysis confirms that our approach could solve the problem efficiently on the one hand, and addresses the question of which genetic operators are best applied to the formulated DCSRP on the other hand
Integrated Cross Sections of the Photo-Neutron Reactions Induced on Au with 60 Bremsstrahlung
Abstract. Seven photo-neutron reactions 197Au(γ,xn)197-xAu (with x=1-7) produced by the bremsstrahlung end-point energy of 60 MeV were identified. In this work, we focus on the measurement of integrated sections. Experiments were carried out based on the activation method in combination with off-line gamma-ray spectrometric technique. The integrated cross sections of the investigated reactions were determined relative to that of the monitoring reaction 197Au(γ,n)196Au. To validate the experimental results, theoretical predictions were also made using the computer code TALYS 1.9. The current integrated cross-sections of the 197Au(γ,xn)197-xAu reactions with 60 MeV bremsstrahlung end point energy are measured for the first time
Effects of chlorogenic acid on porcine oocytes
Chlorogenic acid (CGA) is a quinic acid conjugate of caffeic acid, and a phytochemical found in many fruits and beverages that acts as an antioxidant. The present study investigated the effects of CGA supplementation during in vitro maturation, on in vitro development of porcine oocytes, in order to improve the porcine in vitro production (IVP) system. Oocytes were matured either without (control) or with CGA (10, 50, 100, and 200 µM). Subsequently, the matured oocytes were fertilised, and cultured in vitro for 7 d. The rates of maturation, fertilisation, and blastocyst formation of oocytes matured with 50 µM CGA was significantly (p < 0.05) higher than those of the control oocytes. Hydrogen peroxide (H2O2) is one of the reactive oxygen species and induces DNA damage in porcine oocytes. When oocytes were matured with 1 mM H2O2 to assess the protective effect of CGA, 50 µM CGA supplementation improved the maturation rate and the proportion of DNA-fragmented nuclei in oocytes compared with control oocytes matured without CGA. Moreover, when oocytes were matured with either 50 µM CGA (control) or caffeic acid (10, 50, and 100 µM), the rates of maturation, fertilisation, and the blastocyst formation of oocytes matured with 50 µM CGA were similar to those of oocytes matured with 10 and 50 µM caffeic acid. Our results suggest that CGA has comparable effects to caffeic acid, and in vitro maturation with 50 µM CGA is particularly beneficial to in vitro production of porcine embryos and protects oocytes from DNA damage induced by oxidative stress. Supplementation of CGA to the maturation medium has a potential to improve porcine IVP system
Review of Literature of Faculty Motivation for Doing Research in Universities
Faculty research in the universities plays a very important role in the education and development of every country in the world. The purpose of this research is to review studies in this field, different approaches in studies, and fundamental theories used for studies. The results obtained from the literature review show that many scholars have conducted researches on the determinants influencing the faculty productivity to do research. Most of studies apply the theories of working motivation. However, not many scholars conduct research on the faculty motivation to do research. The final result of this research provides follow-up suggestions for studies of the motivation for conducting research on the side of lecturers, thereby guiding managers to enhance faculty motivation to do research.
