Objective: Bacterial contamination and food poisoning is one of contemporary issues in the early years which many governments like Iran allocate some million dollars a year to medical and social treatment to prevent the implications. Methods: This paper aims to determine the bacterial load in pasteurized milk, produced for Loerstan province market in 2014. During the course of the year, 118 samples were collected and sent to the official laboratory. Results: According to the Iran standard testing protocols, 11% of samples exceeded acceptable range. Conclusions: The diversity of reports is because of different range of personal hygiene, delivery system quality, maintaining equipment and regards for milking. Beside these factors, season of sampling may affect the subject.

Objective: Food and nutrition services are one of the major sources of chemical and biological contamination. It has been anticipated that more than 70% of infectious diseases establish after consuming contaminated foods. Sanitary quality control seems more imperative considering that the confections cover a large proportion of food products in Iran. The purpose of this study is determination of microbial community and presence of Salmonella, Staphylococcus aureus, Escherichia coli, Enterobacteriacea, mold and yeast in confections supplied to Lorestan province. Methods: This research offers a descriptive and analytical perspective on sanitary status of confectionary products during March to April of 2014. Samples included 350 of different types of cake, biscuit, wafer, eclair and cookie which were transported to central food laboratory. Results: According to the tests results 4.28% of eclair samples were contaminated with Enterobacteriaceae out of acceptable range and other samples conform to the prescribed hygiene standards. Totally 0.85% of 350 collected samples were out of standard range. The difference between our result and other researches is related to diversity of sampling time, weather temperature, microbial culture conformity and manufacturing process. Conclusions: The low rate of contamination might appreciate regard for sanitary condition by labors.

Objective: Wheat is a strategic food crop in Iran. General consumption of wheat enhances the public health risk of probable contamination in the wheat products. Wheat is also exposed to different types of the microbial, fungal and chemical agents which could spoil it. This investigation intends to examine products of the flour milling factories for microbial contaminations. Methods: Since March to April 2014, 78 samples of flour produced in the factories of Dorood, Borujerd, Khorramabad, Aligoodarz, Koohdasht, Alashtar, Noor Abad, and Pol-e-Dokhtar were provided and submitted to the laboratory of food and drug administration. The total microbial load and mold population were counted by tests conformed to Iran national standard No. 2393. Results: The obtained results implied the all samples followed microbiological criteria for total microbial load and mold counting. Conclusions: All samples were acceptable and consumable so wheat milling process in the factories of Lorestan province carried out under sanitary condition.

The present study determines the co-authorship factor in the Iranian scientific output between 2000 and 2006 as reflected in the science, social science art and humanities citation indexes made available through the Web of Science database. Webometric indicators were used. The data were extracted in plain text from WOS, analyzed using HistCite software and counted in MS Office Excel program. Of the Total of 25320 documents indexed, 24480 documents were in Science Citation Index, 783 in Social Citation Index and 57 in Art and Humanities index. The findings indicated that co-authorship factor in the period studied had been on the rise. The highest participation rate belonged to the documents with two or three authors. General coauthorship factor was 0.59. The year 2006 had the highest coauthorship factor (0.62) while the year 2000 had the least (0.55). Bradford and Lotka laws were applied to the data sets. The Lotka's Law only held true for the science citation index. The Bradford's Law, however, held true for all indexes. In all citation indexes, the United States with 1865 documents (7.38) had the highest degree of coauthorship in Iranian scientific output.
