The effect of pressure screening fractionation of OCC pulp on several conventional pulp fiber structural defects such as CURL and kink indices evaluated in this research. Aperture velocity and volumetric reject ratio were considered as variable parameters of screening operation and eight trials totally conducted in this work. CURL and kink indices and total kink angle of feed, accept and reject ratio of pulp fiber determined using fiber quality analyzer (FQA). The results of this study showed that pressure screening increased pulp fiber structural defects. Also, it was found that CURL and kink indices and total kink angel of pulp fiber increased as aperture velocity raised but, change in volumetric reject ration didn’t considerably affect structural indices. Refining process of long fiber fraction had an affirmative role on decreasing of fiber structural defects. According to the results of previous works that introduced refining as a suitable device to pulp fiber fibrillation of OCC pulp and findings of this study, refining could be strongly recommended for OCC pulp improvement.

Tomato leaf CURL virus (TLCY, Family Geminiviridae, genus Begomovirus) is a whitefly (Bemisia tabaci) transmitted geminivirus (WTG) causing a destructive disease of tomato in many regions of India, East Asia and Australia. While TLCY isolates from Australia, Bangalore (India) and Taiwan and Tomato yellow leaf CURL virus (TYLCY) isolates from different regions of Asia, Europe and America have a single genomic component (designated DNA A), those from Northern India and Thailand have two components (DNA A and DNA B). Previously, TYLCY-like geminiviruses have been identified from southern provinces of Iran causing leaf CURLing, stunting, and severe reduction in fruits of tomato plants in the fields. We have used degenerate DNA A specific PCR primers to clone part of the genome of an Iranian isolate of TLCY (TLCY-Ir) from field-infected tomato plants growing in Iranshahr, Sistan-Baluchestan Province. Degenerate DNA B-specific PCR primers did not amplify a putative DNA B from infected tomato under conditions that DNA B fragments were amplified from plants infected with Tomato golden mosaic virus, a known bipartite begomovirus. The full-length 2763 nucleotide DNA A genome of TLCY-Ir was sequenced and compared to Iranian isolate of TYLCY (TYLCY-Ir, previously sequenced by Bananej et al., (GcnBank accession No. AJ 132711) isolated from tomato in the same region.As other monopartite TLCV and TYLCV isolates, both TLCV-Ir and TYLCV-Ir genomes contain six open reading frames, two on the virion-sense strand and four on the complementary-sense strand. Sequence comparisons indicated that TLCV-Ir is substantially different from TYLCV-Ir with only 79% nucleotide sequence identity. Phylogenetic analysis showed while the TYLCV-Ir represents an isolate of TYLCV-Israel (TYLCV-Is) group, the TLCV-Ir is closer to TLCV isolates from southern India (TLCVs-Bangalore 2-5) which are most similar to other WTGs infecting tomato and cotton in Pakistan, India and East Asia and differ substantially from T(Y)LCVs of the Middle East, America, Europe and Australia.Presence of two tomato - infecting begomoviruses in the same area provides a favorable environment for recombination of these viruses.

Background and objectives: Carpal Tunnel Syndrome (CTS) is the most common mononeuropathy encountered in clinical practice. Conventional electro diagnosis studies have been useful in the diagnosis of this condition. The Terminal Latency INDEX (TLI) is a derived neurophysiological value that adjusts the Distal motor Latency (DL) for the terminal distance and motor nerve Conduction Velocity (CV).Several studies have suggested utility of the median TLI for diagnosis of CTS.The goal of this study is to evaluate prospectively the sensitivity of the median TLI in the diagnosis of CTS and compare it with other electrodiagnosis techniques.Material and Methods: This study was done on 111 patients as CTS group & 62 healthy subject as control group. In all groups five selected tests of electrodiagnosis were done and all of them were compared with TLI sensitivity.Results: The mean TLI was 0.3±0.05 in the CTS group and 0.42±0.03 in the control group. The sensitivity of TLI was 73% The TLI wasn't statistically better than the other tests, but in three cases from the CTS group, the TLI was the only abnormal test.The 7 and 14 cm method had meaningful sensitivity in contrary to other tests.Conclusion: The sensitivity of TLI has no meaningful difference with other routine electro diagnostic tests in diagnosis of CTS.The median TLI is a useful but not more sensitive electrodiagnostic test for CTS.

Introduction: Three methods of OCRA INDEX, Strain INDEX (SI), and ACGIH HAL have been proposed for the assessment of risk factors of upper limb musculoskeletal disorders. Investigating the correlation and consistency of these three methods are of prominence importance in the workplaces. Thus, this study aimed to determine the correlations of the results of the above mentioned methods. Materials and Methods: In this cross-sectional study, a total of 150 tasks were studied in four industries. For each task, a video taping of a full working cycle was prepared and evaluated according to the instructions of each method. The level of risk exposure to musculoskeletal disorders was analyzed with correlation and Kappa agreement coefficient tests using SPSS (version 16) and R software packages.Results: The correlation between the results of risk assessments of OCRA and SI methods for right and left hands were acceptable and equal to 0.751 and 0.726, respectively (p<0.001). Meanwhile, the coefficients of agreement between OCRA and HAL methods for left and right hands were 0.526 and 0.595, respectively.Conclusion: These findings partly confirmed the agreement between the methods of risk assessment. The origin of this partial agreement can be the number and type of variables and their impacts on the final score of the methods.

Introduction: J.E.Hirsch introduced H INDEX to scientometric domain, representing actual scientific profitability quality of a researcher’s publications; and is equal to effective INDEX for researchers. Literature review: Studies showed that documents database have provided different H scores for each researcher and for different scientific fields. Despite the utmost advantages of H-INDEX it also have some flaws such as need to use complementary indices such as m, r, g INDEX. Conclusions: The strength point of H INDEX, is its ability to use in limited levels which is an complementary for other bibliomeetric exist INDEXes. This INDEX, with others, could be a suit INDEX to improvement scientific levels for researchers, scientist, and scientific board members.

A begomovirus, tentatively named Tobacco leaf CURL Japan virus -JpU (TbLCJV-JpU), was isolated from Lonicera japonica (Honeysuckle) Plants Grown in Utsunomiya showing veinal chlorosis symptoms. The TbLCJV-JpU genome with 2, 761 nt showed a highest identity with TbLCJV-Jp3 and was also close to TbLCJV and as well to TbLCJV-Jp2. The overall nt identity with TbLCJV-Jp3 amounted to 92.94%, while the identities in encoded amino acid (aa) sequence of Coat Protein (CP) and putative products of AC1 and AV2 ORFs were as high as 98.05, 92.54 and 93.96%, respectively. Low sequence identities were observed in the Intergenic Region (IR) of TbLCJV-JpU as compared with TbLCJV, Ageratum yellow vein Taiwan virus-Kochi isolate and Honeysuckle yellow vein virus -Kagoshima isolates. Recombinations were detected in the 5´end (2650 to 2761) and extreme 3´ portion of the genome (220 to 350). Both regions demonstrated high identities with AYVTV-Kochi and HSYVV-Kagoshima. To the best of our knowledge this is the first report of isolation of TbLCJV fromL. japonica.
