The TS of caged or tethered fish (n=76 total) was measured using a Simrad EY60 portable scientific echosounder at 120 kHz. We evaluated the relationship between TS and total length (TL, cm) for the three species. This is the first attempt to use split-beam acoustics to measure single-fish TS in the South China Sea by Chinese researchers. Our results will improve the accuracy and precision of acoustic abundance estimates of commercially important species and fi.trther the development of underwater acoustic survey techniques in fisheries in the South China Sea.展开更多

TOMS is analyzed as an example of a company that took this approach and succeeded. The main research questions try to examine the basic assumptions of TOMS business model in light of shared value concept and uncover the reasons of company's success. The authors claim that two factors played there a crucial role. Firstly the leader whose passion was so contagious that he/she managed to build the team and set up a company based on his/her ideas. Secondly TOMS business model concept (One for One) is convincing for customers who eagerly join the movement. This business case illustrates how a company that is based on social values can grow.展开更多

We isolate the protease-producing Planomicrobium sp. L-2 from the gastrointestinal tract of Octopus variabilis. At least three caseinolytic protease clear bands were observed in zymogram analysis. The crude alkaline protease was highly tolerant of a pH range from 7.0 to 9.0, and temperatures to 50℃ after incubation for 1 h. Proteolytic enzymes were stable towards three surfactants (5% Tween 80, 1% Triton X-100 and 0.05% SDS) and an oxidizing agent (1% hydrogen peroxide), in addition to being highly stable and compatible with popular commercial laundry powered detergent brands available in China. Our study demonstrates the potential these proteases have for development into novel classes of detergent additive. This study also suggests that the gastrointestinal tract of Octopus variabilis may be a rich source of commercially valuable strains of enzvme.展开更多

The specimens were sampled from December 2014 to November 2015, using bottom trawls with various mesh sizes by commercial vessels. The species were Nemapteryx caelatus, Sciades sona, Arius gagora, Batrachocephalus mino, Neturna thalassina, N. bilineata, Osteogeneiosus militaris, Plicofollis dussumieri, P. tenuispinis, Plotosus limbatus, and P. lineatus. Of the eleven species, two species A. gagora and N. bilineata were recorded for the first time and LWRs for four species A. gagora, N. bilineata, S. sona, and B. mino still have no data in the FishBase database. In addition, new maximum length for each of the three species N. bilineata, O. militaris andB. mino was also found.展开更多

Pistachio kernels arc very popular ingredients used in meat products and in the confectionary industry as a part of various pastry products. Historically, Iran has the advantage in supply side and leads the world in pistachio trade. Turkey comes in the third place in terms of production and provides over 70 thousand metric tons of pistachios in 2007, capturing 14 percent production share world wide. As being one of the major habitats of pistachios, Turkey has potential to develop new variaties and increase the productivity, thereby to take advantage of higher profits that may arise from foreign trade in pistachios. Even though pistachio production in Turkey has increased in the last 20 years, this opportunity is yet to be discovered since yield and quality factors are still at low levels, resulting in dramatic losses in foreign market shares. Possible remedies for this problem include irrigation made available to pistachio orchards, adopting new caltivars more tolerant to diseases, preventing the illegal entrance of Iranian pistachios, facilitating the unification of pistachio producers, provoking the consumption of fresh pistachios, and expanding the business into new international markets.展开更多

Therefore, the valuation, even if reflected in accounting reports, is far from objective, and each company considers it in accordance with their sectors or auditors. Auditors, consultants, and business schools are developing alternative tools for measuring these assets, but there is not a consensus formula that quantifies the business value of intangibles. In recent years, communication analysts and consultants have developed brand valuation and reputation methodologies, which are starting to have a relative weight in business management. The proposed research work is a review of the current methodologies of reputation valuation as a starting point for creating a reference model formula for the valuation of intangibles that provide professionals and experts in the field with a worldwide recognized tool.展开更多

Many fungi are serious parasites of seed primordial and maturing seeds and reduce yield of seed both quantitatively and qualitatively. Other fungi, including saprophytes and very weak parasites, may lower the quality of seeds by causing discoloration which may seriously depreciate the commercial value of seeds, particularly of grain when graded for consumption. Studies by using scanning electron microscopy (SEM) confirmed the importance of the seed coat, and seed cells as infection sites as well as location of the mycelium of the investigated fungus. Macrophominaphaseolina The present investigation is undertaken to study the colonization, infection and fungal establishment on different sesame seed parts by (SEM). A successful colonization of M. phaseolina to seed tissues was also detected. Different forms of pycnidial shapes were also observed.展开更多

For the sake of benefits for companies, advertisements in English to promote the sale of goods are essential. Under this circumstance, advertisement is coming into being. Advertising English, as one of the members of advertisement family, has gradually got independence and separated from the common English after a long term development, which has great effects on the form of language itself. Definitely, this development needs more study as well. The advertising English has not only brought precious and vast commercial values to all walks of life, which can be proved in various examples, but also is provided with certain values for appreciation and language study. We all know that life lies in movement. Our familiar sports good industry is standing out particularly in this regard, such as a good and impressive advertisement. A resounding and impressive advertisement can leave people an unforgettable and indelible impression, which certainly will bring endless commercial benefits to this product and also help to establish a favorable brand image. Brand image, with its irreplaceable effects to companies, all starts with the advertising English as a small field of the big advertisement family, because the global communication between sport brands is most outstanding. By doing the research on sport English, we hope the general principles in advertising English canbe summarized and thus achieve the goal of putting English to the economy era to best make use of it.展开更多

The hypothesis is set that company managers do not have permanent values but they change accordingly to the change in economic conditions: in economical welfare situations business-managers more eagerly take larger responsibilities on ethical and philantrophical stages but in crisis only the lower stages (economical and legal ones) could be detained. In the paper, we firstly observe if values change in general and secondly we study if our pre-stated hypothesis holds. As the research method we use the method of critical incidents展开更多

With the development of graffiti art and the improvement of people's aesthetic idea, graffiti has penetrated into various aspects of people's life and has been closely integrated with people's life in many fields. Fashion design is one of the forms which have the closest relation with modem graffiti. Many famous brands have increased their own vitality and fashion sense of costume through graffiti. In modem fashion design, graffiti has special aesthetic value and personality characteristics, bringing about huge commercial opportunities to merchants. Its personality expression in fashion design involves factors in multi-aspects. This paper makes an in-depth analysis of this problem in simple terms, which is of positive significance to the combination of graffiti and fashion design.展开更多

Although a series of achievements have been formed, the deeper research is still needed in the following aspects: how to build parameter estimation model of various variables based on the interaction among customer assets elements and how to get the scientific and available measured data. In order to solve these problems, this paper, based on the characteristics of customer relationship in Business to Business (B to B) enterprise and the analysis of the variable factors in the interactive models will systematically and practically use the seemingly unrelated regression method to construct three main parameters estimation models in the customer assets measurement model, and prove the feasibility of the model through a case study. Research results show that measurement model system constructed by this method solves the problem of interaction and germination among parameters influencing factors. At the same time, factors concentration simplifies data sources to ensure the reliability and objectivity of the data, and thus improve the accuracy and feasibility of the estimation of customer assets value.展开更多

The proposed methodology includes the main figures of economic merit evaluated to each resource assessed, the sensitivity analysis on cash flow, and recommendations of investments to each energy option assessed. A study case is applied within the northwest region of Sao Paulo State (Brazil) for those renewable-energy options. Five options of renewable-energy resources were chosen to be evaluated: three ERs (energy resources) from supply side (small hydro, wind farms and sugarcane bagasse) and two ERs from demand side (replacement of incandescent lighting by fluorescent and replacement of electric showers by central heating systems). The conclusion is that, only two assessed ERs that have received investment grade were sugarcane biomass and fluorescent lamps replacing incandescent lamps. The rest have restriction due different reasons listed.展开更多

The number of intermuscular bones in WCC, PZCC, and GxAT ranged from 78 to 83 (n =81), 80 to 86 (n =84), and 77 to 84 (n=82), respectively. The numbers in ITCC and IRCC were significantly lower, ranging from 77 to 82 ( n =79) and 58 to 77 ( n =71), respectively. The average number of intermuscular bones in each sarco- mere, ranked in order from highest to lowest, was 0.721 (WCC), 0.673 (PZCC), 0.653 (GAT), 0.633 (ITCC), and 0.608 (IRCC). There was no difference between ITCC and GxAT or between GxAT and PZCC. However, the average number of intermuscular bones in the sarcomeres of ITCC, WCC, and PZCC differed significantly, as did that of IRCC and the four other kinds of fish. The intermuscular bone of these five fishes was divided into seven shape categories, non-forked (I), one-end-unequal-bi-fork (), one-end-equal-bi-fork (Y), one-end-multi-fork, two-end-bi-fork, two-end-multi-fork, and tree- branch types. Generally, the morphological complexity was higher in the anterior intermuscular bones than in the posterior body. The number of intermuscular bones was similar but not equal between the left and right sides of the body. ITCC had sig- nificantly fewer intermuscular bones than either WCC or PZCC, making it of greater commercial value. Additionally, IRCC and ITCC had fewer intermuscular bones than WCC. Our observations are significant in both fish bone developmental biology and genetic breeding.展开更多
