The results showed that the mulching treatment by direct seed- ing, the mulching treatment by transplanting, and the exposed treatment by trans- planting performed excellently in bringing seedling stage forward, improving germina- tion rate, yield and quality. For example, seedling emergence stages were 36, 31 and 31 d earlier; germination rates improved by 19.24%, 14.29% and 14.29%; yields grew by 41.98%, 26.72% and 11.45%; starch contents increased by 3.50%, 2.10% and 1.40%, respectively. Therefore, cassava in the mulching treatment by direct seeding is characterized by earlier seedling emergence stage, high germination rate, high yield and quality.展开更多

[Method]Dry matter production and N content of six B.napus parents (Zheshuang 3,Yangyou 7,ZJ1,Shilijia,Ningyou 14 and Huyou 16) and their F1 combinations from 6 × 6 complete diallel cross in maturity stage under two N levels were measured; heterosis of NUEg,combining ability and heritability size were analyzed and calculated. [Result]The results showed that NUEg has obvious heterosis; combining ability variance analysis indicated that NUEg was mainly controlled by additive,dominant and cytoplasmic effects; genetic variance analysis showed that additive effects and dominance effects were all significant in low nitrogen fertilizer and dominance effects were significant in high nitrogen fertilizer. [Conclusion]NUEg of B.napus has obvious heterosis.展开更多
In the wheat-cotton intercropping system, total 6 sowing rates (187.5, 225.0, 262.5, 300.0, 337.5 and 375.0 kg/hm2) were arranged, and the effects of sowing rate on marginal superiority and yield of wheat were inves...In the wheat-cotton intercropping system, total 6 sowing rates (187.5, 225.0, 262.5, 300.0, 337.5 and 375.0 kg/hm2) were arranged, and the effects of sowing rate on marginal superiority and yield of wheat were investigated. The re- sults showed that the effect of sowing rate on inner-line wheat was greater than that on side-line wheat; with the increased sowing rate, the marginal superiority of panicle number was reduced in overall, and the difference in panicle number be- tween inner and side lines was decreased from 9.0×10^5/hm2 (sowing rate of 187.5 kg/hm2) to 7.8×10^5/hm2 (sowing rate of 375.0 kg/hm2); the marginal superiority of grains per spike was increased first and then reduced, and the largest difference in grains per spike between the inner and side lines reached 4.6 under the sowing rate of 300.0 kg/hm2; the marginal superiority of 1 000-grain weight and yield was gradually increased, and the largest difference in 1 000-grain weight between the inner and side lines reached 3.9 g under the sowing rate of 337.5 kg/hm2, and in yield reached 3 136.5 kg/hm2under the sowing rate of 375.0 kg/hm2. The effects of sowing rate on the three yield factors of intercropped wheat ranked as panicle number 〉 grains per spike 〉 1 000-grain weight. The appropriate sowing rate of wheat was 225.0-262.0 kg/hm2 in the wheat-cotton intercropping system.展开更多

The real estate market has shifted from being undersupplied to having an equilibrium of supply and demand with regional oversupply. Real estate risks in some cities have begun to emerge, but overall real estate risks remain controllable. Given the major changes taking place in the supply and demand of China's real estate market and the current stage of its development, it is projected that China's real estate investment growth will continue to slow down during the 13th Five-year Plan period and pressures on the renovation of inventory housing will intensify. According to the changes in the development of China's current real estate market, the objectives of real estate development will be adjusted to put a higher premium on the development level, the quality of real estate development, and the improvement of housing conditions. Reform and policy adjustments should be carried out to effectively prevent real estate market risks and to achieve stable operations inside the real estate market itself.展开更多

The results showed that germination potential and rate both improved around 5% and the num- ber of root increased by 4% in the treatments with ultra-fine powder shaped maize seed coating agent compared with the control group without seed coating. What's more, the treatments with ultra-fine powder shaped maize seed coating agent took advantages in terms of fresh weight of seeding, stem diameter, and dry weight. It is notable that control effects on underground insects performed the best, with per- centage over 94%, which is more excellent relative to other agents in markets. Therefore, ultra-fine powder shaped maize seed coating agent can be widely applied in spring sowing areas in northeast China, without side effects.展开更多

But at the same time, major coal mining accidents still exist nowadays. In order to review the overall situation and provide information on major accidents of coal mines in China, we investigated 26 major coal mining accidents in China between the years of 1949 and 2009 through statistical methods, each of which led to more than 100 fatalities. Statistical characteristics about accident-related factors such as time, death toll, accident reasons, characters and nature of enterprise were analyzed. And some special conclusions have been achieved. For example, although we have made great progress, the safety situation in China coal mining industry is still serious, and the reasons for the mining accidents are all human errors which are not inevitable. Such results may be helpful to prevent major accidents in coal mines. Moreso, based on both the knowledge of other countries which have good safety situation nowadays and the safety management situation of China, we made suggestion on safety management of China coal mining. In conclusion, countermeasures were proposed in accordance with the results of statistical studies and the analyses of problems existed in coal mines, including the perfec- tion of safety supervision organization, the establishment of cooperating agency among government, coal mines and workers, the perfection of safety rules and regulations, the improvement of safety investment, the enhancement of safety training, the development of safety technique, and the development of emer- gency rescue technique and equipment.展开更多

Maize (Zea rnays L.) cv. "Vijay" (composite), green gram (Vigna radiata L.) cv. "Samrat", black gram (Vigna mungo L.) cv. "Sarada", soybean (Glycine max L. Merril) cv. "PK 327" and peanut (Arachis hypogaea L.) cv. "JL 24", were tested in monoculture as well as in intercropping situations with 1:1 (additive series) and 1:2 ratios (replacement series). The result indicated that intercropped legumes improved the yield components of maize and offered some bonus yield. The highest maize grain yield (2,916.28 kg/ha) and maize equivalent yield (4,831.45 kg/ha) were recorded with maize + green gram (1:1) and maize + peanut (1:I), respectively. The values of all the competition functions were always greater than unity and maize + black gram (1:2) recorded the highest values of land equivalent ratio (1.433), area time equivalent ratio (1.374) and land equivalent coefficient (0.421). Maximum monetary advantage (Rs. 10,579.13) was found with maize + green gam (l:1). Maize + peanut (1:2) combination recorded the highest relative net return (2.01), net return (Rs. 28,523.08), benefit-cost ratio (2.76) ad per day return (Rs. 259.30).展开更多

Larval survival and growth during all life stages (larvae, spat, and adult) were compared among hybrid (DW, WD) and purebred (DD, WW) populations. Significant heterosis was detected for survival during the larval stage (〉 1% of the mid-parent values). The mean heterosis (Hm) varied in growth throughout the life span. More than 50% of the Hm values were positive and negative in the DW and WD groups, respectively. The influence of maternal effects and mating types (intrapopulation vs. interpopulation crosses) on growth for all life stages was not consistent. Larval survival did not differ significantly (P〉0.05) with maternal effect or mating type. In the harvest stage, shell length (SL), shell height (SH), shell width (SW), and total weight (TW) were larger in the hybrid compared with the inbred groups. Positive Hm values were observed in SL (1.5%), SW (5.8%), and TW (12.3%), and were more significant in the DW groups (6.1%, 4.5%, 6.8%, and 27.2%). These results suggest that hybridization between two geographic populations is a good tool for improving bay scallop growth. However, unstable heterosis between the two populations requires further study.展开更多

Hen...The superiority of wheat grain yield under no-till has been reported by many authors, and others reported significant interaction between wheat cultivar and tillage system for grain yield and other related traits. Hence, new breeding initiatives are needed to introgress favorable traits into wheat and other crops in areas where no-tillage is being adopted. The identification of such traits is solely possible via the assessment ofgermplasm under no-tillage. Moreover, Moroccan wheat breeding programs are carried out solely under conventional tillage system whilst the conservation one is becoming widely adopted. So, the ultimate objective of this research is to find out if the used wheat commercial cultivars behave differentially under no tillage system and to propose the use of appropriate cultivars for the appropriate tillage system and to implement a breeding program specifically for no tillage system. The experiment has been carried out during 2006-2007 at Douyet (F6s). Cultivars have been sown according to a strip-split plot design. At maturity, yield, yield components and related traits have been recorded. The results indicated that both water regime (WR) and variety (Vat) had a highly significant effect on all measured traits. In contrast, tillage system (TS) had similar effect on yield, grains m-2, biomass, and plant height, but had no effect on harvest index, 1000-kernel weight and heading date. The TSxVar interaction has been significant to highly so on all traits except on heading date. The magnitude of the interaction for grain yield was more important under irrigated treatment than under rainfed one. On the whole, No Tillage yielded more grains than conventional one. Moreover, Achtar and Areal (bread wheat cultivars) and Marjana and Marzak (durum wheat cultivars) yielded more under No-Till. The significant interaction between TS and Var paves the way for the implementation of a breeding program under no till system.展开更多

By using internal analysis of market and nonmarket variables, we detail how the future growth rate of the middle class is dependent on three issues: domestic consumption trends of Generation Y in China, the valued opportunity of the science and technology industry, and the importance of maintaining a strong work force able to increase productivity. In particular, we discuss market demands from Generation Y, products best suited for Chinese consumers, and the effect social-economic inequalities in Western China will have on development measures of the middle class. Based on data collection, interviews, library research and econometric analyses, we show how these above issues will continue to influence consumer behavior, reform policies, and the growth of the middle class in China. It is important to note that economic growth and prosperity in China will only continue if the national government and private institutions, along with the international agendas of other countries, are in balance, and not excess, of the resources and capabilities available for desired growth levels.展开更多

With a relationship between the reaction rate con- stant and the electrode potential, we find that the heat dissipation βq equals to the dynamic irreversibility of the reaction system minus an internal entropy change term. The total en- tropy change Ast is defined as the summation of the system entropy change As and the heat dissipation/βq such that △st=△s+βq. Even though the heat dissipation depends linearly on the electrode potential, the total entropy change is found to satisfy the fluctuation theo- rem 〈e-△st 〉=1, and hence a second law-like inequality reads (△st)≥0. Our study provides a practical methodology for the stochastic thermodynamics of electrochemical reactions, which may find applications in biochemical and electrochemical reaction systems.展开更多

Brands financial values are not quantified in balance sheets, so quantifying them provides important financial data. This is the research topic. The research questions are: (i) How is the importance of the brand in the revenues of football clubs and (ii) what is the financial value of the brands Futebol Clube do Porto (FCP), Sport Lisboa e Benfica (SLB), and e Sporting Clube de Portugal (SCP)? This investigation was based on an adaptation of the inter brand equity model. This model considers equity as the economic value generated as net profit of the company, which can be apportioned to the brand. The data was collected from the financial maps of these three clubs between 2005/2006 and 2009/2010 seasons. In order to adapt the model to the football industry, a panel of five experts of professional football club managers was questioned. These experts claim that in football industry, brand management contributes with 16% of the economic value, sport management with 63%, financial management with 16%, and other factors with 5%. The conclusion is that FCP has the most valuable brand, with about 54.5 m , followed by SLB with about 51.6 m , and finally by SCP with about 39.5 m.展开更多

High correlations ranging from 0.973 to 0.999 indicate that ERA-Interim could capture the annual cycle very well. However, an average root-meansquare error(rmse) of 3.7°C for all stations reveals that ERA-Interim could not be applied directly for the individual sites. The biases can be mainly attributed to the altitude differences between ERA-Interim grid points and stations. An elevation correction method based on monthly lapse rates is limited to reduce the bias for all stations. Generally, ERA-Interim captured the Plateau-Wide annual and seasonal climatologies very well. The spatial variance is highly related to the topographic features of the TP. The temperature increases significantly(10°C- 15°C) from the western to the eastern Tibetan Plateau for all seasons, in particular during winter and summer. A significant warming trend(0.49°C/decade) is found over the entire Tibetan Plateau using station time series from 1979-2010. ERA-Interim captures the annual warming trend with an increase rate of 0.33°C /decade very well. The observation data and ERA-Interim data both showed the largest warming trends in winter with values of 0.67°C/decade and 0.41°C/decade, respectively. We conclude that in general ERA-Interim captures the temperature trends very well and ERA-Interim is reliable for climate change investigation over the Tibetan Plateau under the premise of cautious interpretation.展开更多

The image of the place of origin influences the assessment of products and brands (brand image) they come from. Traditionally, consumers extrapolate the characteristics of the country and its inhabitants on the characteristics of the product. Chinese products are very common and they can be purchased almost anywhere. The consumer does not have to take any special efforts to acquire products "made in China". Many of these products do not have specific characteristics that allow them to be considered as the unique. Products, whose names indicate the place of origin, are witnessing an increasing popularity. In the case of products "made in China", the matter is different. Often, consumers do not admit that they purchase goods produced in China. Research on consumer behaviour in the market of chines products, conducted among Polish citizens, indicated that these products are readily bought. This article presents the results of the research on consumers' attitudes towards regional "made in China" which was conducted in April 2015 among Polish citizens. Furthermore, the article will include the comparison of attitudes towards Chinese products between consumers from Poland and other European countries.展开更多

文摘The research explored adaptability maize seed coating agent in spring sowing and effects of ultra-fine powder shaped areas in northeast China. The results showed that germination potential and rate both improved around 5% and the num- ber of root increased by 4% in the treatments with ultra-fine powder shaped maize seed coating agent compared with the control group without seed coating. What's more, the treatments with ultra-fine powder shaped maize seed coating agent took advantages in terms of fresh weight of seeding, stem diameter, and dry weight. It is notable that control effects on underground insects performed the best, with per- centage over 94%, which is more excellent relative to other agents in markets. Therefore, ultra-fine powder shaped maize seed coating agent can be widely applied in spring sowing areas in northeast China, without side effects.

文摘From the year of 1949 to the present, the China national coal output has been increasing quickly and became first in the world in 2009. But at the same time, major coal mining accidents still exist nowadays. In order to review the overall situation and provide information on major accidents of coal mines in China, we investigated 26 major coal mining accidents in China between the years of 1949 and 2009 through statistical methods, each of which led to more than 100 fatalities. Statistical characteristics about accident-related factors such as time, death toll, accident reasons, characters and nature of enterprise were analyzed. And some special conclusions have been achieved. For example, although we have made great progress, the safety situation in China coal mining industry is still serious, and the reasons for the mining accidents are all human errors which are not inevitable. Such results may be helpful to prevent major accidents in coal mines. Moreso, based on both the knowledge of other countries which have good safety situation nowadays and the safety management situation of China, we made suggestion on safety management of China coal mining. In conclusion, countermeasures were proposed in accordance with the results of statistical studies and the analyses of problems existed in coal mines, including the perfec- tion of safety supervision organization, the establishment of cooperating agency among government, coal mines and workers, the perfection of safety rules and regulations, the improvement of safety investment, the enhancement of safety training, the development of safety technique, and the development of emer- gency rescue technique and equipment.

文摘This study describes the complete diaUel hybridization between newly introduced bay scallop stock (W) from Canada and local commercial stock (D) grown under laboratory conditions, in China. Larval survival and growth during all life stages (larvae, spat, and adult) were compared among hybrid (DW, WD) and purebred (DD, WW) populations. Significant heterosis was detected for survival during the larval stage (〉 1% of the mid-parent values). The mean heterosis (Hm) varied in growth throughout the life span. More than 50% of the Hm values were positive and negative in the DW and WD groups, respectively. The influence of maternal effects and mating types (intrapopulation vs. interpopulation crosses) on growth for all life stages was not consistent. Larval survival did not differ significantly (P〉0.05) with maternal effect or mating type. In the harvest stage, shell length (SL), shell height (SH), shell width (SW), and total weight (TW) were larger in the hybrid compared with the inbred groups. Positive Hm values were observed in SL (1.5%), SW (5.8%), and TW (12.3%), and were more significant in the DW groups (6.1%, 4.5%, 6.8%, and 27.2%). These results suggest that hybridization between two geographic populations is a good tool for improving bay scallop growth. However, unstable heterosis between the two populations requires further study.

The magnitude of the interaction for grain yield was more important under irrigated treatment than under rainfed one. On the whole, No Tillage yielded more grains than conventional one. Moreover, Achtar and Areal (bread wheat cultivars) and Marjana and Marzak (durum wheat cultivars) yielded more under No-Till. The significant interaction between TS and Var paves the way for the implementation of a breeding program under no till system.
文摘This study provides an evaluation of China's growing middle class, the new consumers for world economies and estimated to be 300-500 million people. By using internal analysis of market and nonmarket variables, we detail how the future growth rate of the middle class is dependent on three issues: domestic consumption trends of Generation Y in China, the valued opportunity of the science and technology industry, and the importance of maintaining a strong work force able to increase productivity. In particular, we discuss market demands from Generation Y, products best suited for Chinese consumers, and the effect social-economic inequalities in Western China will have on development measures of the middle class. Based on data collection, interviews, library research and econometric analyses, we show how these above issues will continue to influence consumer behavior, reform policies, and the growth of the middle class in China. It is important to note that economic growth and prosperity in China will only continue if the national government and private institutions, along with the international agendas of other countries, are in balance, and not excess, of the resources and capabilities available for desired growth levels.

文摘In this work, we discussed the stochastic thermodynamics of mesoscopic electron transfer reactions between ions and electrodes. With a relationship between the reaction rate con- stant and the electrode potential, we find that the heat dissipation βq equals to the dynamic irreversibility of the reaction system minus an internal entropy change term. The total en- tropy change Ast is defined as the summation of the system entropy change As and the heat dissipation/βq such that △st=△s+βq. Even though the heat dissipation depends linearly on the electrode potential, the total entropy change is found to satisfy the fluctuation theo- rem 〈e-△st 〉=1, and hence a second law-like inequality reads (△st)≥0. Our study provides a practical methodology for the stochastic thermodynamics of electrochemical reactions, which may find applications in biochemical and electrochemical reaction systems.
文摘As in many other industries, strong brands play an important role in football industry inducing sales for the clubs that own it. Brands financial values are not quantified in balance sheets, so quantifying them provides important financial data. This is the research topic. The research questions are: (i) How is the importance of the brand in the revenues of football clubs and (ii) what is the financial value of the brands Futebol Clube do Porto (FCP), Sport Lisboa e Benfica (SLB), and e Sporting Clube de Portugal (SCP)? This investigation was based on an adaptation of the inter brand equity model. This model considers equity as the economic value generated as net profit of the company, which can be apportioned to the brand. The data was collected from the financial maps of these three clubs between 2005/2006 and 2009/2010 seasons. In order to adapt the model to the football industry, a panel of five experts of professional football club managers was questioned. These experts claim that in football industry, brand management contributes with 16% of the economic value, sport management with 63%, financial management with 16%, and other factors with 5%. The conclusion is that FCP has the most valuable brand, with about 54.5 m , followed by SLB with about 51.6 m , and finally by SCP with about 39.5 m.

文摘In this study, surface air temperature from 75 meteorological stations above 3000 m on the Tibetan Plateau are applied for evaluation of the European Centre for Medium-Range Weather Forecasts(ECMWF) third-generation reanalysis product ERA-Interim in the period of 1979-2010. High correlations ranging from 0.973 to 0.999 indicate that ERA-Interim could capture the annual cycle very well. However, an average root-meansquare error(rmse) of 3.7°C for all stations reveals that ERA-Interim could not be applied directly for the individual sites. The biases can be mainly attributed to the altitude differences between ERA-Interim grid points and stations. An elevation correction method based on monthly lapse rates is limited to reduce the bias for all stations. Generally, ERA-Interim captured the Plateau-Wide annual and seasonal climatologies very well. The spatial variance is highly related to the topographic features of the TP. The temperature increases significantly(10°C- 15°C) from the western to the eastern Tibetan Plateau for all seasons, in particular during winter and summer. A significant warming trend(0.49°C/decade) is found over the entire Tibetan Plateau using station time series from 1979-2010. ERA-Interim captures the annual warming trend with an increase rate of 0.33°C /decade very well. The observation data and ERA-Interim data both showed the largest warming trends in winter with values of 0.67°C/decade and 0.41°C/decade, respectively. We conclude that in general ERA-Interim captures the temperature trends very well and ERA-Interim is reliable for climate change investigation over the Tibetan Plateau under the premise of cautious interpretation.
文摘This article introduces the analysis of strategic management of film production companies. The first part presents processes and models of strategic management and introduces a new and unified model of strategic management. It is noteworthy that the film/film industry value chain helps to understand the notion that the links between separate stages have an impact on the company's competitive advantage and reveal how the main product in the film industry, the feature film, is developed. Therefore, the following part analyses models and composition of film industry value models. The final part of this article analyses the main features of a film production company and the sources of funding thereof. The strategic model of independent film production companies is based on the characteristics of strategic management and the value chain models of independent film projects.
文摘In the eyes of consumers, each product has some kind of origin (its country, region, and continent). The image of the place of origin influences the assessment of products and brands (brand image) they come from. Traditionally, consumers extrapolate the characteristics of the country and its inhabitants on the characteristics of the product. Chinese products are very common and they can be purchased almost anywhere. The consumer does not have to take any special efforts to acquire products "made in China". Many of these products do not have specific characteristics that allow them to be considered as the unique. Products, whose names indicate the place of origin, are witnessing an increasing popularity. In the case of products "made in China", the matter is different. Often, consumers do not admit that they purchase goods produced in China. Research on consumer behaviour in the market of chines products, conducted among Polish citizens, indicated that these products are readily bought. This article presents the results of the research on consumers' attitudes towards regional "made in China" which was conducted in April 2015 among Polish citizens. Furthermore, the article will include the comparison of attitudes towards Chinese products between consumers from Poland and other European countries.
