This work is focused on the purification of soap factory wastewaters by a combined system planted of emerged macrophytes. The exploitation of this combined system planted reveals substantial results after twenty weeks of the purification of wastewater. Neutralization of the pH of filtered water and its cooling. Almost all suspended matter is removed (95%) from the filtered waters. Significant reductions in ammonium (75%) and nitrite (69%) contents are observed. Using this combined system planted, high removal rates of orthophosphates (56%) and anionic surfactants (81%) are obtained. The removal rate of organic matter is about 76% in BOD5 and 42% in COD.

Organizational researchers have long debated the meaning and consequences of organizational culture but the relationship between culture and organizational performance is still not well understood. Organizational culture is the collective behavior of humans who are part of an organization and the meanings that the people attach to their actions. Culture includes the organization values, visions, norms, working language, systems, symbols, beliefs and habits. The purpose of this study is to investigate the effect of organizational culture on the relationship between transformational leadership among elementary school teachers. In present study, five organizational culture aspects devised by Hafstede are used and their relations with leadership are measured. This is a survey – type descriptive research and data collection method is field study by using questionnaire. On this basis, 150 questionnaires were used in analyses from total among elementary school teachers in Kermanshah. Canonical correlations indicated “a modernly high relationship between leadership and organizational culture. The author found that the cultural elements of accomplishment, recognition, and affiliation tend to be positively correlated with all aspects of transformational leadership. The findings supported that transformational leadership practices are positively correlated with a constructive organizational culture, and that transformational leadership practices predict organizational culture. The results of this study will ensure confidence in the practice of employing and developing transformational leaders so that an innovative and constructive organizational culture, vital for organizational survival in the 21st century, could be Accomplished. The advantages of a constructive organizational culture transcend financial outcomes such as return on investment and profitability.

Brand name play a vital role when people look for products to purchase, use and to evaluate before they buy or dispose of products and services in which they expect will satisfy their wants and needs. In the present scenario companies use consumer driven approaches to substantiate their abilities to satisfy the countless emerging needs and wants of the modern consumer. Amongst these consumer driven approaches, branding has emerged as one of the crucial activities required in the building of a loyal customer base and the creation of an effective brand image. Consumers want to associate themselves with certain brands and this makes a large influence on their buying behavior . Understanding consumers’ behaviour is a crucial factor in the companies’ success around the world. Brand is a combination of name, symbol and design. Brands represent the customer’s perceptions and opinion about performance of the product. The powerful brand is which resides in the mind of the consumer. Brands differ in the amount of power and worth they have in the market place .The purpose of this paper is to analyze role of brand name when people take a purchase decision, especially in the purchase of car. The objective is to identify if buyers of passenger cars consider the brand name as an important cue while evaluating different alternatives.

The word entrepreneur originates from the French word, entreprendre, which means "to undertake." In a business context, it means to start a business. The Merriam-Webster Dictionary presents the definition of an entrepreneur as one who organizes, manages, and assumes the risks of a business or enterprise. Many experts and researchers refer to today's world as the age of discontinuity. Age of discontinuity means that past experience and solutions to current and future problems are not entrepreneur anymore and should think for new organizational solutions with modern structure, so that could produce the goods and services with minimal cost and with superior quality tailored to customer needs and preferences as global markets be subdued and captured and in this great race to be victorious. Therefore in order to have successful economics there dire need to have prosperous enterprises in competitive environments. This requires powerful, self-reliance and empowered employees, the Personnel who possess the creative and entrepreneurial morale. As result entrepreneurship, creativity, innovation and risky businesses, provide fuel modern economy that means in any enterprise if in any organization, the entrepreneurial context of a ewe be provided employment will be created and itself will be factor of technology transformation. Entrepreneurs are a factor to identify, create and expand new markets they have the ability to see market gaps and to identify opportunities perfectly. In other words, entrepreneurship is nothing but the opportunity recognition and optimum use of it. Therefore we consider the entrepreneurship as suitable strategy for development and improvement of enterprises in this paper and we believe that entrepreneurship has important role in productivity enhancement and to ease their innovative activities in order to implement the organization's success.

Ductal carcinoma is a rare tumor, which accounts for 1 to 3% of all malignant salivary gland tumors primarily affecting middle-aged men with a high potential for metastasis. In salivary gland neoplasms, rhabdoid cells are not commonly seen. We report the case of a 58-year-old man, who presented a mass of the left cheek evolving for 3 months, who underwent an exofacial parotidectomy, the extemporaneous histopathological analysis of the specimen revealed a ductal carcinoma with rhabdoid features. We completed by a total conservative parotidectomy of the facial nerve. Salivary duct carcinoma with rhabdoid features should be distinguished from malignant lymphoma, malignant melanoma, and myogenic sarcomas. Transformation to ductal carcinoma with rhabdoid features has occurred in metastatic lesions. Treatment was based on extensive carcinological resection with postoperative radiotherapy with regular follow-up.

The noninfectious disease, diabetes increases the risk of the infectious disease TB. In developing countries TB remains a major cause of mortality and in these countries the prevalence rate of diabetes in increasing rapidly. In this study, totally 1200 number of TB clinic attendees were included and blindly screened for the diabetes. Random blood sugar was checked for the selected population. Blood samples were tested by glucometer. Out of 1200 TB clinic attendees, diabetes was diagnosed with 750 patients (63%). From our study, we conclude that the TB clinic attendees are at high risk and showing high percentage of DM. We also suggest that the danger of the co-existence of TB and DM should be explored and to be taught to the society especially to the TB clinic attendees to ensure the effective treatment.

Data aggregation system is the majority sensible technique for wireless sensor networks. It reduce a large amount of communication. To screen announcement during aggregation homomorphism encryptions have been practical in previous be taught. So the enciphered data can be aggregated algebraically without decryption. Although data aggregation could considerably reduce broadcast, it is defenseless to some attacks. However, these schemes failed to satisfy multi-application surroundings. The main drawback of these scheme is that, it become insecure in case a number of sensor nodes are compromised. Also, these scheme do not provide secure counting. Thus, it is suffer due to unauthorized aggregation attacks. An alternative move toward for this problem is to collective encrypted messages in a straight line from SN, thereby avoid the forgery of aggregate result. To end these drawbacks, we propose a new hidden data aggregation system called CDAMA, provide CDA connecting multiple groups. It is extensive from homomorphism community encryption system. There are three contributions in the proposed system. First, it is intended a multi-application surroundings. Next, it mitigates the crash of compromising attack in single request environments. Compared with conservative schemes, CDAMA mitigates the collision of compromise SN from beginning to end the construction of manifold groups. It reduces the damage from illegal aggregations.

The present study was carried out to investigate the effect of key word method on the retention rate of Iranian EFL learners. Thus far, the studies on the efficiency of key-word method, as a strategy of vocabulary learning, have indicated mixed results, and reached no conclusive findings. To carry out the study, 40 students were chosen from among university students registered for English classes in Isfahan University. They were all pretested to make sure that they did not know the target words that were supposed to be taught in order to find out their retention rates. All the learners were divided into two groups: one key-word method group (KWMG) and one rehearsal method group (RMG). The same set of words was taught to both groups. For the first group, we used key-word method and we let the students to choose and use their own key words, which would lead to deeper processing of information, in order to enhance long term retention. For the second group only rehearsing of the new words was used. At the end of experiment, two tests were administered: one immediate test to check out their short term retention and one delayed post test to measure their long-term recall. The results of the study have shown no significant difference in short term retention but with regard to long-term retention, the Key-word method group students outperformed the rehearsal group. In addition, in a semi- structured interview with key word method group students, it was revealed that they show a great interest in the method, and maintained that they would opt for the method when memorizing other words.

In this study, the effects of seven nanofilm types on organoleptic properties have been investigated and microbial counts of packed volume bread have been studied. Packed of volume bread has been evaluated due to 21 days at three temperatures. Microbial counting was done in 5°C, 20°C and 35°C in fourteenth day. The results analysis indicated that the main factors such as film type, storage temperature and duration had significant effect on the bread staling rate. The lowest and highest staling rate was observed at SC3 film and control regular respectively. With the increasing nanosilver percentage, the total number of microbes declined. In three temperatures greatest number of total germs and mold was related to the control regular. Lowest and the most number of total molds and microbes was found in 5°C and 35°C respectively. Therefore, the SC3 hybrid nanofilm, has been recognized as the best film for keeping bread more fresh.
