Fur- thermore, after soils softening, seedling slinging or direct seeding was adopted, which is dominated by natural rainfall and supplemented by artificial irrigation. The test proved that the technology help increasing yield and profits over 20%, with chemical fertilizer reduced by more than 10%, and labor cost reduced by 10%. What's more, if the technology applied once, no-tillage or slight tillage is recom- mended in the field, which would maintain original eco-conditions of soils and reach high yield, with energy, water, labor costs reduced in an environment-friendly way.展开更多

Nevertheless, these techniques could be applied in engineering processes as well in order to improve the effectiveness and the efficiency of manufacturing processes in BI (building industry). Focusing on the case study of GLT (glued-laminated timber), this paper shows the procedure of programming a parametric algorithm adopted by authors that pursues two specific design intents: reducing the usage of unneeded high-quality raw material and improving the efficiency of production processes by producing DF (digital fabrication) contents for standard production systems of GLT. According to different European and international standards, thanks to FEM (finite element model) simulations and curvature analysis, the algorithm allows saving at least 33% of high-quality raw material and, according to early first surveys on a standard production system, 30% of operation time among product engineering-processes.展开更多

It is known for value added product from fish processing and the adhesive agent for wood paper book binding etc. This work was aimed with the method to produce fish glue from fish skin through representing optimum fish type and its glue character by study on standard method for fish glue processing (using Oreochromis niloticus skin as the model), optimum fish type and characterization of the glue from optimum fish skin. Soaking fish skin in 0.1 N NaOH for 6 h and changed it every 3 h for pretreatment before acid extraction with 0.5 M acetic acid was the optimum condition for the standard processing. Among 20 types (O. niloticus, Oreochromis sp., Nemipterus sp., Psettodes erumei, Epiephelus malabaricus, Sphyraena obstsata, Channa striata, Xenentodon cancila, Barbonymus gonionotus, Liza vaigiensis, Anabas testudineus, Chanos chanos, Micronema bleekeri, Thunnus tonggol, Rastrelliger brachysom, Epinephelus lanceolatus, Lutjanus lineolatus, Pomadasys hasta, Selar crumenophthalmus and Sardaorentalis sp.), Chanos chanos was an appropriate type for glue production. Fat, protein, carbohydrate, moisture, pH and viscosity of Chanos chanos glue were 0.32%, 4.23%, 83.8%, 11.56%, 3.35, 4,978.33-8,180 cp, respectively. The glue was collagen type I which was composed ofal (148 kDa) and a2 (129 kDa) chain and could bind paper, wood and foam sheet.展开更多

Gambiered Guangdong silk is a kind of natural product. All its raw materials are reproducible and degradable natural resources, and it can decompose completely when being discarded. R is comfortable to wear, and easy to clean and dry. It is mainly manufactured by dip-dyeing in dye yam solution, and insolating under the burning sun. The production energy is solar, a kind of clean and reproducible energy. The production process is clean and environmental friendly. There is neither the utilization of synthetic dyestuff and chemical auxiliary, nor the discharge of environment pollutant, and even the dreg of dye yam is used as fuel. The safety test results show that pH value of water extract, heavy metal content (except for Pb content), color fastness and odor meet the requirements of GB/T18885 - 2002 and Okeo-tex standard 100.展开更多

The topography, wide rainfall variation and varied temperature conditions enable inhabitancy of several plant species. This plant wealth is being used in various forms by tribes and natives of the area for centuries. These gain further importance due to the fact that ripe fruits serve as a source of food and medicine to tribes throughout the year. These wild fruits are source of minerals and vitamins in the diet of the rural people. The potential productivity and floristic diversity of the area have attracted the experts. There are more than 50 wild edible fruit species are available in Western Ghats region. These belong to 25 families and 38 genera. Out of the 25 families, the important ones as a source of fruits are Apocynaceae, Anacardiaceae, Euphorbiaceae, Moraceae, Sapotaceae and Sapindaceae. The fruiting period of different species ranges between two and six months. The highest number of species mature from April to May. The availability of these fruits reduces after October. Some of these fruits, such as Mangifera indica, Artocarpus heterophyllus, Carissa carandas, Emblica officinalis and Syzygium cuminii, have been given emphasis in order to identify high yield and high fruit quality clones and standardization of production technologies. The collection, conservation and utilization on some of the fruits, such as Garcinia indica and Garcinia gummigutta have started at various research organizations. Some other fruits, namely Chrysophyllum roxburghii (Family Sapotaceae), Canthium parviflora Lamk syn. Plectronia parviflora (Lam.) Bedd. (Family Rubiaceae), Elaeagnus conferta Roxbsyn, Elaeagnus latifolia L. (Family Elaeagnaceae), Securina leucopyrus syn. Flueggea leucopyrus (Family Euphorbiaceae), Elaeocarpus tuberculatus Roxb. (Family Elaeocarpaceae), Nephelium stipulacum Bedd. syn. Doratoxylon stipulatum (Family Sapindaceae) have potential for commercial cultivation. Thus, attempts were made with the objective of recording availability of these species, proximate analysis and their on farm and off farm conservation at Central Horticultural Experiment Station (CHES). Few plants were also provided to local growers on farm conservation. The continuous depletion of forest and the increasing human disturbance resulted in losses of these species. There is need to conserve these fruits for future.展开更多

"Well-off society" is a relatively vague concept, and the contents of it ceaselessly change with the advancement of society and the development of productivity. Now the construction of a well-off society in an all-round way enters a critical stage, so the original evaluation standards must change with gradual advancement of the construction goal of a well-off society. So it is very necessary for us to build a comprehensive evaluation index system and make it better and better to provide effective statistical consultation and statistical supervision for constructing a well-off society in an all-round way. This paper attempts to analyze the current evaluation index system, then puts forward the general thinking and flame work of the index system of building a well-off society in an all-round way.展开更多

The EC (European Commission)-Mixing Zone Guidelines were applied to seven effluent discharges. The effluents were from industrial processes used in the Ronnskar smelter, in northern Sweden. Each outlet in the smelter area discharges water into the Bothnian bay of the Baltic Sea. Cadmium (Cd), mercury (Hg), nickel (Ni) and lead (Pb) were the primary substances present in the effluents. A "Tiered Approach" was followed for mixing zone assessments in each of the discharge points. Discharge Test was used at Tier 2 and CORMIX (Cornell Mixing Zone Expert System model), version 7, at Tier 3. At each discharge point, the AA-EQS (annual average-environmental quality standard) for each metal was met within a distance of 500 m from the outfalls. This distance was exceeded to meet the MAC-EQS (maximum allowable concentration-environmental quality standard) criteria at points 1 and 3 for total Hg concentrations. However, for the proper application of Mixing Zone Guidelines, a version of the Discharge Test for coastal waters should be developed and used. The decision at which tier the dissolved metal concentration should be compared with EQS values could depend on the effluent characteristics. For Swedish coastal waters, some consideration should be given to the background concentration of metals.展开更多

Distributions of tt^- invariant mass and that for transverse momentum of top quark with respect to Standard Model and unparticle production are predicted. An odd valley with scalar unparticle contribution appears for some values of du, which is due to the big cancellation between the contribution from SM and that from unparticle. This character may be used to study the properties of scalar unparticle. Our investigations also show that scalar unparticle may play a significant role in tt^- production at the photon collider if it exists.展开更多

Effectively beekeeping today means using several pastures per year with a yield of 50-60 kg per hive. Mobile beekeeping is the only way to achieve high yields of production and it has considerable advantage over stationary one which is less rentable. Mobile beekeeping require higher investments and labor but with good climate and ecological conditions, one can achieve several times higher income than in stationary beekeeping. Some of the success in mobile beekeeping depends of the selection of hives. The hives must be designed to give the bees the best environment for work and development to be most efficient. Data was collected from 57 beekeepers that live in the district. Data analysis was conducted by using standard statistical and economic processes. Criteria for a recommended for the proposed beekeeping model were incomes and profit per hive. For effective beekeeping and production of bee products, especially honey, beekeeper must have adequate equipment and a good bee hives. Beekeeper must have transportation and additional equipment because their movement depends season on the season and distance to pasture.展开更多

We find that the production cross section is larger than that of the process γγ→ W+ H-H in the minimal supersymmetric standard model. With reasonable values of the parameters in the TC2 model, the cross section can reach the level of a few fb. Furthermore, the flavor-changing (FC) decay mode ∏t^0 → te^- is the best channel to detect the neutral top-pion due to the clean SM background. With a large number of events and the clean background, the neutral top-pion should be observable at future linear colliders operating in γγ mode at the TeV energy scale.展开更多

In the processes for the "production of many models in small quantities" by multi-skilled workers, a manufacturer cannot make good use of the management method with standardized work tables used by large enterprises. Thus, it is necessary to develop ways to f'md standardized work that is suitable for smaller enterprises. Therefore, we investigated two kinds of factories that utilized flexible manufacturing procedures for the "production of many models in small quantities," and considered their work instructions, work contents, changeover methods, workers' abilities, etc. One of the compared processes was a case where there was defined standardized work, which was not observed. In the other, a QA (quality assurance) network was created to guarantee the quality. Based on the investigation results, we formulated improvement plans, had the supervisors review them, and clarified the characteristics of their problems. The results revealed areas where much attention was required to find standardized work for such processes. In addition, we made it possible to support the specification of difficult tasks and the renewal of standardized work by extending a standardized work table for the entry of workers' actions. This paper reports a method to define and make good use of standardized work tables and standardized work combination tables, i.e., a way to find and use standardized work based on the results of the previously mentioned factory investigation.展开更多

These evaluations are generally supported by three sources: estimations of using country-specific macroeconomic data on which they can determine patterns of growth, inflation, unemployment, productivity, income per capita, etc.; timely data on current conditions and developments in production, income and spending; and institutional information on policy makers, business practices and financial markets. This paper focuses on the first two where we examine the publically available macroeconomic data for the Kingdom of Bahrain to determine their reliability. Among our findings are: (1) creating a reliable data base of macroeconomic data is difficult due to data revision and incomplete data gathering; (2) the movement of standard macro-variables is often unusual, leading one to question further the reliability of the data; (3) based on available data it appears that the growth in Bahrain has been driven almost solely by an increase in the number of people working, with little to no apparent rise in productivity; and (4) the growth of GDP will eventually be constrained by physical limits on population growth, and can be improved only if ways can be found to increase the productivity of the workforce.展开更多

文摘In the context of topcolor-assisted technicolor (TC2) model, we study the charged and neutral top-pions production process γγ →W+ ∏t-∏t^0. We find that the production cross section is larger than that of the process γγ→ W+ H-H in the minimal supersymmetric standard model. With reasonable values of the parameters in the TC2 model, the cross section can reach the level of a few fb. Furthermore, the flavor-changing (FC) decay mode ∏t^0 → te^- is the best channel to detect the neutral top-pion due to the clean SM background. With a large number of events and the clean background, the neutral top-pion should be observable at future linear colliders operating in γγ mode at the TeV energy scale.
文摘Many smaller manufacturers utilize production systems such as "individual production" and the "production of many models in small quantities." In the processes for the "production of many models in small quantities" by multi-skilled workers, a manufacturer cannot make good use of the management method with standardized work tables used by large enterprises. Thus, it is necessary to develop ways to f'md standardized work that is suitable for smaller enterprises. Therefore, we investigated two kinds of factories that utilized flexible manufacturing procedures for the "production of many models in small quantities," and considered their work instructions, work contents, changeover methods, workers' abilities, etc. One of the compared processes was a case where there was defined standardized work, which was not observed. In the other, a QA (quality assurance) network was created to guarantee the quality. Based on the investigation results, we formulated improvement plans, had the supervisors review them, and clarified the characteristics of their problems. The results revealed areas where much attention was required to find standardized work for such processes. In addition, we made it possible to support the specification of difficult tasks and the renewal of standardized work by extending a standardized work table for the entry of workers' actions. This paper reports a method to define and make good use of standardized work tables and standardized work combination tables, i.e., a way to find and use standardized work based on the results of the previously mentioned factory investigation.
文摘Business analysts worldwide use the standard theories and tools of macroeconomics and finance to determine the investment, trade or production possibilities in foreign markets. These evaluations are generally supported by three sources: estimations of using country-specific macroeconomic data on which they can determine patterns of growth, inflation, unemployment, productivity, income per capita, etc.; timely data on current conditions and developments in production, income and spending; and institutional information on policy makers, business practices and financial markets. This paper focuses on the first two where we examine the publically available macroeconomic data for the Kingdom of Bahrain to determine their reliability. Among our findings are: (1) creating a reliable data base of macroeconomic data is difficult due to data revision and incomplete data gathering; (2) the movement of standard macro-variables is often unusual, leading one to question further the reliability of the data; (3) based on available data it appears that the growth in Bahrain has been driven almost solely by an increase in the number of people working, with little to no apparent rise in productivity; and (4) the growth of GDP will eventually be constrained by physical limits on population growth, and can be improved only if ways can be found to increase the productivity of the workforce.
