In this research, Lactobacillus casei and Lactobacillus acidophilus bacteria were added to watercress drink and the physicochemical properties, antioxidant activity, viability of probiotic bacteria and sensory characteristics of the samples were investigated in the period of 1, 15 and 30 days after production. The results showed that the pH in all samples decreased significantly with time. Brix of the samples containing higher amounts of watercress was more, and with the passage of time, the turbidity of all samples decreased significantly. The samples containing higher amounts of watercress had higher total phenol and antioxidant activity, and with the passage of time, the IC50 of all samples increased significantly and their total phenol decreased significantly. On the 1st and 15th days, the highest viability rates of both microorganisms belonged to samples containing 75% watercress. Watercress extract helped the viability of Lactobacillus casei and Lactobacillus acidophilus with its antioxidant activity and significant phenolic compounds. The results of the sensory evaluation showed that there was no statistically significant difference in the score of flavor, aroma, texture, color and overall acceptability of the samples on all the days investigated.

The concept of virtual water has considerable potential to help improving water management, especially in the agricultural sector. Therefore, virtual water analysis of basic products of the agricultural sector can help us in policy-making and planning in the optimal use of water resources. In this study, the amount of virtual water and its related indicators were determined using the basic approach and then, based on the amount of production and demand of the province for agricultural products, the amount of agricultural exchanges and the trade balance of virtual water in Hamadan province in 2018 were estimated. The results showed that the trade flow of the studied products has a volume equal to 924.7 million m3 of virtual water exports outside the province and 33.4 million m3 of virtual water imports into the province. Based on this, the trade balance of virtual water was estimated at 891.3 million m3. These results show that Hamedan province produces and exports water-intensive products within the province. The positive and significant trade balance warns of the need to change the cultivation pattern in the province due to the lack of water resources. According to the results of the study, it is suggested that the area under cultivation of crops such as corn, beans and alfalfa with high virtual water content be reduced and crops such as fodder corn and sugar beet, which require less virtual water, be replaced.

A library and information specialist cannot rely only on his academic views. He can perform his job successfully only when he has access to his colleagueschr('39') scientific knowledge which is based on their experiences and uses it alongside his own knowledge. Therefore, it is essential and necessary to identify the ways of transferring the tacit knowledge of librarians and the factors affecting this transfer in order to improve the current conditions. Thus, The purpose of the present study is to identify the methods of tacit knowledge transfer and sharing and factors affecting it among the librarians of public libraries in Fars Province.

This study is an applied research that was conducted by the survey method. The research population included all 400 librarians of the public libraries in Fars Province, from whom 190 librarians were selected by using simple random sampling. The data collection tool was a questionnaire. The validity of this questionnaire was measured by asking for the opinions of information science specialists and its reliability was confirmed by Cronbach chr('39')s alpha coefficient (α= 0.82 ). Furthermore, the SPSS (v.21) and Microsoft Excel (2016) were applied to analyze the data. Prioritization of the methods of tacit knowledge transfer and the factors affecting it were performed using the Kruskal-Wallis test, and the multiple linear regression and its coefficients were used to measure the relationships between the influential factors and the demographic characteristics of librarians.

The results indicated that the most important methods of transferring knowledge between librarians of public libraries in Fars Province were verbal communication between library staff and their participation in in-service training courses, respectively. From the perspective of respondents, all three factors, including personal, organizational and technological, affect the tacit knowledge transfer; The need for a proper reward system (among the organizational factors), access to Internet (among the technological factors) and maintaining the job position (among the personal factors) have been the most important factors from the viewpoint of librarians. However, in the overall comparison, organizational factors were assigned the highest score and personal factors were assigned the lowest score by the librarians. Results of the regression equation also confirmed the existence of a significant relationship between the librarianschr('39') age and gender and the technological factors.

So far, no research has been conducted within the country on the methods of tacit knowledge transfer and the factors affecting it among the librarians of public libraries. Therefore, the current research can pave the way for other studies in this field. In addition, among the studied factors, organizational factors and then technological factors were assigned the highest scores by librarians. Paying attention to these results can be useful in the short and long term planning of Iran Public Libraries Foundation in order to facilitate and reinforce tacit knowledge transfer among librarians. Furthermore, the results of the research showed that the existence of joint agreements and programs between Iran Public Libraries Foundation and universities, educational and research centers in order to hold different training courses can be effective in facilitating knowledge sharing.

One of the most commonly used methods for evaluating the academic activities of a university is the scientometrics that is possible using databases.

Epstein-Barr virus (EBV) is a tumorigenic herpes virus and belong to DNA viruses that infects and persists in B lymphocytes in the majority of humans and also is associated with a portion of cases of Hodgkin lymphoma (HL). The aim of the present study was to investigate the presence of Epstein-Barr virus in Hodgkin's lymphoma through EBERs in situ hybridization (EBERs-ISH) in children Iranian. In this study, 16 Hodgkin's lymphoma tissue samples formalin-fixed paraffin embedded blocks collected from the archive of departments country hospitals. Samples were obtained from the tissue cancer biopsies, The presence of RNA transcripts encoded by Epstein-Barr virus were analyzed with EBERs in situ hybridization (EBERs-ISH). Data analyzed by SPSS16 statistical software, Fisher's exact test. The presence of Epstein-Barr virus (EBV) in 16 formalin-fixed, paraffin-embedded samples of Hodgkin's disease (HD) was investigated by EBERs in situ hybridization. 12 samples were from male (75%) and 4 samples were from female (25%). Age range of Patients was 4 -12 years (with a median of 8 years). In 12 specimens (75%) Epstein-Barr virus was present. The positive cases included 9 male samples (75%) and 3 female samples (75%). Fisher's exact test showed statistically no significant difference between sex (p-value: 1.000). Epstein-Barr virus was present in different subtypes of Hodgkin's lymphoma. 80% (4 of 5) of Mixed Cellularity (MC), 67% (6 of 9) of Nodular Sclerosis (NS) and 100% (2 of 2) of Lymphocyte Predominance (LP) subtypes were positive. There is not significant different between subtypes (p-value: 0.826). The presence of Epstein-Barr virus in the age groups of 4-7 and 8-12 years were 71.5% (5 of 7) and 77.8% (7 of 9), respectively. There is not significant different between age groups (p-value: 1.000). Study results show strong association between Epstein-Barr virus and Hodgkin lymphoma in Iranian children. Epstein-Barr virus and Hodgkin lymphoma association in Iranian children show similar pattern with other developing countries.

The Epstein-Barr Virus (EBV(is related with various diseases including infectious mononucleosis، Burkitt''s lymphoma، Hodgkin''s lymphoma، nasopharyngeal carcinoma and post-transplant lymphoprolifrative disorders. The aim of this study was to characterize the association between EBV and Hodgkin''s lymphoma through EBERs in situ hybridization (EBER-ISH) in Iranian patients. In this study، 43 Hodgkin''s lymphoma tissue samples were selected from formalin-fixed paraffin embedded blocks and analyzed by EBERs in situ hybridization. Data analyzed by SPSS16 statistical software، Fisher''s exact test and Mantel-Haensel significant level 0. 05. 43 Hodgkin''s lymphoma patients were 29 (67%) male samples and 14 (33%) female samples. In 20 (47%) samples Epstein-Barr virus was present. The positive cases included 13 samples male and 7 samples female. Fisher''s exact test showed statistically no significant difference between sex and subtypes. Age distribution of relation of Hodgkin''s lymphoma and EBV virus were 75% (12 of 16) in the age group of 1-14 years، 22% (5 of 23) in the age group 15-49 years and 75% (3 of 4) in the age group over 49 years، respectively. Fisher''s exact test showed statistically significant difference between 1-14 and 15-49 age group years (p-value: 0. 003). Results shown higher presence rate of Epstein-Barr virus in Hodgkin''s lymphoma specimens of children and older adult. This pattern is similar to other developing countries.
