Comparative Evaluation of Different Treatment for Purulent Wounds in Dogs

Open Journal of Veterinary Medicine 2016年第7期6卷 119-126页

作者： ahmad massoud niazi Mohammad Monir Tawfeeq Amanullah Aziz Jahid Zabuli Shahpoor Rahmati Abdul Razaq Irshad Clinic Department Faculty of Veterinary Science Kabul University Kabul Afghanistan

To compare the healing of purulent wounds with Shilajit dressing vs. Vishnevsky dressing in dogs with purulent wounds of >2 weeks of duration, eight dogs were chosen from same ages in two groups i.e., Shilajit and Vishnevsky dressing group. Dressing was done on every day basis for more than two weeks of follow up period. Main outcome of healing measure was completed at three weeks. Wound healing status was assessed at three days intervals till end of three weeks. Shilajit treated achieved complete decrease in the wound surface area, effect of healing score in Shilajit dressing group in comparison to the Vishnevsky dressing group at p > 0.05 level of significance. Shilajit is highly effective in achieving a characteristic feature of regenerative and granulation healing of purulent wounds as compared to Vishnevsky dressing group in dogs.

Use of Random Regression Test-Day Model to Estimate Genetic Parameters of Milk Yield in Holstein Cows

引用

Open Journal of Animal Sciences 2018年第1期8卷 27-38页

作者： Yaser Fazel Masoud Asadi Fozi Ali Esmailizadeh Fatemeh Fazel ahmad massoud niazi Shahpoor Rahmati Mohammad Ibrahim Qasimi Department of Animal Science Faculty of Veterinary Kabul University Kabul Afghanistan Department of Animal Science Faculty of Agriculture Shahid Bahonar University of Kerman Kerman Iran Faculty of Veterinary Ferdowsi University of Mashhad Mashhad Iran Department of Clinic Faculty of Veterinary Kabul University Kabul Afghanistan

(Co) variance components and genetic parameters were estimated for milk yield of Iranian Holstein cows. A total number of 68,945 milk test-day records of first, second and third lactations of 8515 animals from 100 sires and 7743 dams originated from 34 herds collected during 2007 to 2009 by Iranian animal breeding center were used. The ASReml computer program was used to analyze the milk test-day records using the random regression procedure. Herd test date (HTD), milking times per day (milking frequency), number of lactations, year of birth, year of calving, age of animal at calving and days in milk (DIM) considered as fixed effects and additive genetic effects and animal permanent environmental effects were considered as the random effects. Additive genetic variance, animal permanent environment variance, residual variance, phenotypic variance, heritability and repeatability were estimated during different months of lactation between 5.7 - 19.6, 15.3 - 27.1, 31.4 - 17.2, 45.8 - 64.83, 0.1 - 0.32 and 0.4 - 0.6, respectively. Genetic correlation and phenotypic correlation were also estimated between months of lactation in range of -0.35 - 0.98 and 0.03 - 0.67, respectively. Genetic correlation and phenotypic correlation both showed the same changing pattern and they decreased as the interval between months of lactation increased.

Numerical analysis of intermodal delay in few-mode fibers for mode division multiplexing in optical fiber communication systems

引用

Optoelectronics Letters 2012年第2期8卷 138-141页

作者： Abid Munir 忻向军刘博 Abdul Latif Aftab Hussain Shahab ahmad niazi School of Electronic Engineering Beijing University of Posts and Telecommunications State Key Laboratory of Information Photonics and Optical Communications Beijing University of Posts and Telecommunications Beijing Key Laboratory of Work Safety Intelligent Monitoring Beijing University of Posts and Telecommunications

In order to achieve higher spectral efficiency, mode division multiplexing (MDM) in few-mode fibers is a new research area. The idea faces lots of technical issues including intermodal delay and mode coupling which limit the achievable length of the system. This paper is designated to complete the analysis of intermodal delay in step-index few-mode fibers. We analyze numerically all the parameters of fiber, which could impact intermodal delay in few-mode fibers and identify the conditions which can increase the number of multiplex modes without significant increase in maximum intermodal delay.

Co-existence generation of XG-PON and single carrier XLG-PON for ultra-high definition TV transmission with entirely passive optical plant

引用

Optoelectronics Letters 2013年第3期9卷 221-224页

作者： Shahab ahmad niazi 张晓光席丽霞 Abid Munir Muhammad Idress State Key Laboratory of Information Photonics and Optical Communication Institute of Information Photonics and Optical Communication Beijing University of Posts and Telecommunications

International telecommunication union (ITU) recently has standardized ultra-high definition television (UHD-TV) with a resolution which is 16 times more than that of current high definition TV. Increasing the efficiency of video source coding or the capacity of transmission channels will be needed to deliver such programs by passive optical network (PON). In this paper, a complete passive co-existence of 10 Gbit-PON (XG-PON) and single carrier 40 Gbit-PON (XLG-PON) for overlay of UHD-TV distribution to 32 optical network units (ONUs) on broadcast basis is presented. The results show error free transmission performance with negligible power penalty over a 20 km bidirectional fiber.
