尚坤：力哥在领奖台上快哭了

全运会开始前，尚坤的心里是忐忑的。上海队已经集训了一个半月，和河南队、北京队、浙江队都一起合练过，但尚坤的信心还是不太足。“今年改了球，我前半年状态比较差，人也拢不到什么方向。”看了看小组赛的对手，尚坤说：“我们和河北队不好打，对粱靖崑我赢的比较少；河南队的任浩我也几乎没赢过。所以在看了小组赛对手后，我心里比较忐忑。”但一想到这一个半月的集训，想到尽职尽责的教练、队医，尚坤又对自己说：“全力以赴去打就好，在场上不用想太多，做好自己就行。”

Velocity of a Liquid Drop with a Sorption-Controlled Surfactant

The terminal velocity of a liquid droplet settling in a sulfactant solution has been studied for the non-linear adsorption Langmuir frameworks accounting for monolayer saturation and non-ideal surfactant interactions. Most prior research uses a linear adsorption model which cannot capture these effects, The Maragoni migration of a liquid drop settling through a surfactant solution is examined by using Langmuir framework. The solution concentration Ceq is assumed large enough for the surfactant mass transfer to be adsorption-controlled. Langmuir model generates non-linear Marangoni stresses which diverge in the limit of approaching ∝, strongly retarding U'.

Leaching kinetics in cyanide media of Ag contained in the industrial mining-metallurgical wastes in the state of Hidalgo, Mexico

The leaching kinetics in cyanide media of the silver contained in the Dos Carlos waste tailings at the City of Pachuca de Soto, Hidalgo State, Mexico were carried out. The used material contained the following chemical composition: 56 10-6of Ag, 0.6 10 6of Au and 70.43%(by weight) of SiO2; 7.032%(by weight) of Al2O3; 2.69%(by weight) of Fe; 0.46%(by weight) of Mn; 3.98%(by weight) of K2O; 3.34%(by weight) of CaO; 2.50%(by weight) of Na2O; 0.04%(by weight) of Zn; 0.026%(by weight) of Pb. The mineralogical phases present were the following: Silica, albite, argentite, berlinite, orthoclase, potassium jarosite, and natrojarosite. In the leaching kinetics in cyanide media, and under the studied conditions,the effect of the CN concentration on the reaction rate has no effect on the whole process of alkaline cyanidation, of which the reaction order is n 0. Temperature has an effect on the cyanidation rate of the reaction, with an activation energy of 47.9 KJ/mol. At the same time, when the particle size decreases there is an increase in the reaction rate, which is inversely proportional to the particle diameter; when increasing the NaOH concentration there is an increase in the reaction rate Kexp, with a reaction order(n) of 0.215 under the studied ranges.

Landslide risk perception and communication for disaster risk management in mountain areas of developing countries：a Mexican foretaste

The increasing impact of disasters at local,national,regional and global scales in recent decades has provided enough evidence to urgently direct attention towards the necessity of disaster risk reduction and management,and this requires knowledge.Knowledge without communication is barren,and to communicate the risk of disaster it is necessary to understand the perception of the people at risk.In particular,this paper deals with the necessity to delineate strategies of risk communication in pursuance of risk knowledge as a core of disaster risk reduction and management,especially in mountain areas of developing countries.To portray this issue,an analysis of landslide risk perception in terms of experience,landslide risk awareness,exposure,preparedness,and risk communication and trust was undertaken in the municipality of Teziutlán,Puebla,Mexico,an area that has been affected for several decades by episodes of mass movement.Analysis of the responses to a risk perception questionnaire has offered valuable insights in terms of the information and knowledge most required by the people living in the area of interest,in order to devise a realistic and functional strategy to communicate the risk of a landslide disaster.This includes better understanding of controlling factorsand drivers of this risk,and the establishment of potential trusted sources of risk communication.Beyond considering practical matters of risk assessment and management,risk perception and communication can increase the resilience of vulnerable people,and can enhance capacity building for present and future generations.

Effects of Transportation Stress during the Hot-Dry Season on Some Haematological and Physiological Parameters in Moroccan Dromedary Camels （Camelus dromedarius）

The purpose of this study was to determine the effects of road transportation under heat conditions on some haematological [Ht （haematocrit）, blood cells count and EOF （erythrocytes osmotic fragility）] and physiological [Tr （rectal temperature）, HR （heart） and RR （respiratory rates）, and circulating levels of Cor （cortisol）, Glu （glucose） and minerals] parameters in Moroccan dromedary camels. The animals were subjected to road transportation stressor for 2 h by truck during the hot-dry season. Blood samples were collected before loading and transport, and at the end of transport. Transportation induced a significant increase （P 〈 0.05） of erythrocytes count, Ht, EOF, Tr, HR and RR by comparison to values observed before transportation. The same stress conditions induced a significant increase （P 〈 0.05） of plasma Cor （ng/mL） and blood Glu （mM） （220 ± 30 vs. 137 ± 20, 9.7 ± 1.2 vs. 6.4 ± 1. 1 respectively） and a significant decrease （P 〈 0.05） of plasma magnesium （mM） （0.5 ± 0.1 vs. 0.9 ± 0.1） comparatively to pre-transportation values. These results indicate that road transportation associated to heat may be considered as a potent stressor which is able to induce several cellular alterations in camels. Further studies of an eventual protective role of vitamin C against haemolysis induced by transportation stress in camel are needed.

Wind Energy Generation Potential in Union Hidalgo, Mexico： A Preliminary Study

Union Hidalgo municipality in Oaxaca State, Mexico, is located in an area with attractive wind potential. For this reason, this paper presents a preliminary study of the technical feasibility of wind power generation in Union Hidalgo, by a micro-study with a higher resolution than that used in Wind Resource Atlas of Oaxaea, published in April 2004. In this work, the wind map of Union Hidalgo was generated using the micro-scale model WAsP 9.1, with a resolution of 50 meters. Wind speed and direction data recorded at 15 m and 32 m agl （above ground level） over four years and seven months in a surface anemometer station were used. With Class 7 wind patterns, the results show values that justify the installation of wind turbines to produce electricity in the area. Estimated capacity factors （55% on average） are comparable with those obtained in wind power plants already operating in areas near Union Hidalgo and sites with high wind potential in other parts of the world. The topography of the study area is predominantly flat, and together with the directional behavior of the wind, which comes from the NNW 44% of the time, this favors the introduction of wind power plants in the area.

＂Questionable＂ Behaviors and Practices in Academic Productivity in Postgraduate Studies in Mexico

This paper reports the results acquired in a research work about ＂questionable＂ practices and behaviors in the academic production of researches and postgraduate social sciences and humanities studies of the programs that are appointed by the National Program of Quality Postgraduate Studies （PNPC, by its acronym in Spanish） in Mexico. Through a qualitative methodology, the authors interpreted some of the arguments that explain and/or justify certain practices in relation to doubled production, authorship, and coauthorship of academic products. In this paper, the authors present and analyze the results that they obtained after reviewing documents produced by professors and students of six postgraduate programs that are taught in two Mexican public universities. At the same time, the authors examine some of the practices that take place within said programs, given the institutional demands of improving finished studies efficiency. One of the hypotheses of this work is the demands that are imposed by external evaluations of academic processes on professors and their programs in order to reach desirable rates with the purpose of maintaining or increasing the levels of productivity, gives way to certain practices that must be analyzed. This work＇s theoretic framework is constituted by the contributions of career sociology and professional ethics.

Territorial Competitiveness in a Globalised Economy： Regional Efficiency of the Mexican Service Sector

The existence of a solid service sector and some degree of specialisation in tertiary activities are among a number of territorial diversity of factors which need to be taken into account in relation to the creation of competitive capacities. In addition globalisation has presumably played a significant role in the productive restructuring of economies in which the service sector has had an increasing quantitative and qualitative importance over the years Therefore, an evaluation of the role of services in constructing regional competitive capacities is required. This paper aims at addressing indirectly the meaning of services on improving competitiveness by providing a wide-ranging analysis of regional efficiency of the Mexican service sector and its determinants as well as an overview of its territorial distribution and special isation patterns. We evaluate the patterns of concentration of the third sector and its branches, and specialisation of regions. The efficiency of the service sector in the NAFTA period is analysed further because of the impact of services on regional competitiveness. We employ state leve data to examine technical efficiency＇s differentials across regions and their determinants. The methodology includes data envelopment analysis to measure technical efficiency which is the dependent variable in a reduced form model that links regional performance with a number of proxies for various types of agglomeration economies such as specialisation, urbanisation and internal economies of scale

Benguela CommunitylUNAM Wind Power Demonstration Projectm——Experiences in Implementation

The government of Namibia has committed itself to promote the use of economically viable RE （renewable energy） technologies, as a complement to grid electrification, and to improve energy provision to rural areas. This paper presents the implementation of the Benguela Community-UNAM Wind-Power Demonstration Project, which is a community-run wind-power mini-generation pilot plant in Luderitz, Namibia. Luderitz is located in South-Western Namibia along the Namib Desert. The region experiences abundant south-westerly winds and the coastal weather conditions make it a suitable location for wind energy. This project is an initiative from the community of Luderitz and a first of its kind in Namibia. It demonstrates the application of small-scale wind energy systems in Namibia and contributes to the growing national awareness of RE and use of wind power in the country. Through its activities, the project has created a dialogue between the local authorities, business community, schools and the greater community. The balance of the paper discusses lessons learned; envisaged future development plans; highlights technical, administrative and management activities; as well as potential for replication and barriers encountered during the project implementation including institutional constraints. The solution-methods developed are presented and discussed.

Fate Processes of Chlorobenzenes in Soil and Potential Remediation Strategies: A Review

Chlorobenzenes （CBs） are a group of organic pollutants that pose a high environmental risk due to their toxicity, persistence and possible transfer in the food chain. Available data in literature show that CBs axe detected in different environmental compartments such as soil, water, air and sediment. The widespread presence of CBs in the environment is related to their former extensive use in agriculture and industry. Some CBs are ranked in the list of priority pollutants by the Stockholm Convention, and their reduction or elimination from the environment is therefore of high importance. Environmental risk assessment of CBs requires knowledge on the role and importance of the main environmental fate processes, especially in soil. Furthermore, development of remediation strategies for reduction or elimination of CBs from the environment is related to the enhancement of fate processes that increase their dissipation in various environmental compartments. The main objectives of the current review were to present up-to-date data on fate processes of CBs in the soil environment and to explore possible remediation strategies for soils contaminated with CBs. Dechlorination of highly-chlorinated benzenes is the main degradation pathway under anaerobic conditions, leading to the formation of lower-chlorinated benzenes. Biodegradation of lower-chlorinated benzenes is well documented, especially by strains of adapted or specialized microorganisms. Development of techniques that combine dechlorination of highly-chlorinated benzehes with biodegradation or biomineralization of lower-chlorinated benzenes can result in useful tools for remediation of soils contaminated with CBs. In addition, immobilization of CBs in soil by use of different amendments is a useful method for reducing the environmental risk of CBs.
