Canning of non exportable shrimps

The shrimp can with three compounds of salted water, oil, and sauce, in view of the organoleptic characteristics were compared to each other. Also the effects of processing methods including freezing, drying and canning were evaluated according to some qualitative parameters to raw shrimp (blank). The result showed that considering the organoleptic characteristics, the shrimp can with the compound of oil was better than the two others. On the other hand, the pH of the shrimp can, containing oil was 7.44 ± 0.01, freeze shrimp 7 ± 83-0.04 and dried shrimp 7.46 ± 0.01, that according to the T test, comparing to the blank these differences were statistically meaningful (P <U/01). The amount of protein in freeze shrimp was 96.2 ± 0.03, in dried shrimp 81 ± 0.7 and in canned shrimp (containing oil) was 76.8 ± 0.92, these differences were also statistically considerable. The quantity of the T.V.N in freeze shrimp was 0 ± 0.53, dried shrimp 66 ± 0.3 and in canned shrimp (containing oil) was significant. In view of the total number of the microorganisms, in freeze shrimp was 4800 per gram, in the dried shrimp 15500 per gram, and in the canned shrimp was negative

Assessment of research performance and educational research needs of Iran’s Dental schools-2004

Background and Aim: Compared to the information about educational responsibilities, there is not much information about the research skills and activities of the academics in dental schools. The aim of this study was to evaluate the research performance of the academic staff of the dental schools and their educational needs to promote their research skills. Materials and Methods: This cross-sectional study was done by mailing a questionnaire to all of the members of Iran dental faculties. The questionnaires contained personal information like age, sex, place of employment, educational records, and additional questions like the workshops previously attended, and interests to attend certain workshops. To evaluate the research performance of the academic staff, the number of accomplished researches, the articles published in known national and international journals, their skills in using internet, and the number of attended workshops about research methodology were included in the questionnaire. The completed questionnaires were gathered and evaluated by descriptive statistics. Results: From the questionnaires gathered, 436 were eligible to be included in the study, which formed 58% of the academic staff of dental schools. The results showed that 7.4% of the staff had more than 10 researches conducted, 15% had 5-10, 49.9% had less than 5, and 27.7 had no researches done. Considering the articles published in known national journals, 28.2% had no papers, 51.8% had 1-5 papers, and 20% had more than 5 papers. Regarding the number of articles published in known international journals, 77.5% had no papers, and 20.2% had 1-3, and 2.3% and more than 3 papers. The "preliminary research methods" workshop had the highest percent of participation (71.6%), and "Stata acquaintance" workshop had the least (0.7%). The participants were mainly interested to participate in three workshops, "English scientific writing" (26.3%), "principles of scientific writing" (17.5%), and preparing research proposals" (16.2%), respectively. Conclusion We concluded that the research skills and performance of the academic staff, though improved in the recent years, is still unsatisfying. In order to promote it, it is recommended to organize workshops about "research methodology", "scientific writing" and "preparing of proposals

Semi-flocking-controlled mobile sensor networks for tracking targets with different priorities

Semi-flocking algorithms have been demonstrated to be efficient in maneuvering MSNs in multi-target tracking tasks. In many real-world applications, targets can be assigned with different priorities according to their importance of being tracked. However, existing semi-flocking algorithms normally assume the importance of all targets to be identical, which may not allocate resources in an efficient manner. In this paper, we propose a target evaluation method that incorporates priorities of the targets in the assessment process. Based on the evaluation results, mobile agents decide to track a target or continue to scan the terrain via a probabilistic task switching mechanism. Simulation results indicate a higher effectiveness of the proposed method in target tracking and area coverage when compared with two existing semi-flocking algorithms.Department of Electronic and Information Engineering201905 bcrcpreprint_postprin
