AIM： To evaluate the surgical scars of external dacryocystorhinostomy （DCR） cosmetically. METHODS： Totally 50 consecutive cases of primary acquired nasolacrimal duct obstruction （PANDO） were included in the study. Surgical scars were assessed by the patients and two independent observers at 2, 6 and 12wk postoperatively on the basis of visibility of the scars and still photographs respectively and were graded from 0-3. Kappa test was utilised to check the agreement of scar grading between the two observers. Wilcoxan signed ranks test was used to analyse the improvement of scar ***： Thirty-four （68%） patients graded their incision site as very visible （grade 3） at 2wk. At 6 and 12wk, incision site was observed as grade 3 by 7 （14%） and 1 （2%） patients respectively. Photographic evaluation of patients by 2 observers showed an average score of 2.75, 1.94 and 0.94 at 2, 6 and 12wk respectively. Change in scar grading from grade 3 to grade 0 in consecutive follow-up （2, 6 and 12wk） was found to be highly significant both for the patient as well for the observers （P〈0.0001）.CONCLUSION： The external DCR is a highly effective and safe procedure and in view of low percentage of cases who complained of marked scarring in the present study, thus scarring should not be the main ground for deciding the approach to DCR surgery, even in young cosmetically conscious patients.

Three Tier Fog Networks: Enabling IoT/5G for Latency Sensitive Applications

引用

China Communications 2019年第3期16卷 1-11页

作者： Romana Shahzadi Ambreen Niaz Mudassar ali Muhammad Naeem Joel J.P.C.Rodrigues Farhan Qamar syed Muhammad Anwar University Engineering and Technology COMSATS University Islamabad Wah campus National Institute of Telecommunications (Inatel) Instituto de Telecomunicac??es University ITMO University of Fortaleza (Unifor)

Following the progression in Internet of Things(IoT) and 5G communication networks, the traditional cloud computing model have shifted to fog computing. Fog computing provides mobile computing, network control and storage to the network edges to assist latency critical and computation-intensive applications. Moreover, security features are improved in fog paradigm by processing critical data on edge devices instead of data centres outside the control plane of users. However, fog network deployment imposes many challenges including resource allocation, privacy of users, non-availability of programming model and testing software and support for the heterogenous networks. This article highlights these challenges and their potential solutions in detail. This article also discusses threetier fog network architecture, its standardization and benefits in detail. The proposed resource allocation mechanism for three tier fog networks based on swap matching is described. Results show that by practicing the proposed resource allocation mechanism, maximum throughput with reduced latency is achieved.

Measuring Porosity of Anodes in Solid Oxide Fuel Cell (SOFC) through Water Archimedeans Porosimetry

引用

Journal of Power and Energy Engineering 2015年第6期3卷 46-53页

作者： syed Mubashar Hassan syed ali Hasnain School of Engineering and Built Environment Edinburgh Napier University Edinburgh UK Centre of Excellence in Sustainable Building Design School of Energy Geosciences Infrastructure & Society Heriot-Watt University Edinburgh UK

The present research is aimed to measure the porosity of anodes in solid oxide fuel cell through water Archimedeans method. There are various alternatives available to replace fossil fuel cells like nuclear power, wind energy, solar energy, bio fuel, and geothermal and fuel cells. Among all the alternatives of fossil fuel, one form of energy production that stands out from the rest and promises a sustainable future energy is fuel cell. Moreover, it offers many advantages in contrast to other forms of energy generation. An Archimedean approach for water immersion porosimetry is carried out. Some of the results are beyond rational limits, and given negative and sometime above 100 percent porosity. The reasons for these unacceptable results are either due to water ingress into the sample or the sample turns into buoyant due to air in the cling film. The results from Archimedean porosimetry should only be used qualitatively due to errors associated with the results. It is also noted that Archimedean porosimetry is not the ideal technique for measuring the porosity of coated samples. It is suggested that larger samples should be analyzed that will help to minimize the weighing errors.

The intricate anatomy and physiology of cranial nerves have inspired clinicians and scientists to study their roles in the nervous system. Damage to motor cranial nerves may result from a variety of organic or iatrogenic insults and causes devastating functional impairment and disfigurement. Surgical innovations directed towards restoring function to injured motor cranial nerves and their associated organs have evolved to include nerve repair, grafting, substitution, and muscle transposition. In parallel with this progress, research on tissue-engineered constructs, development of bioelectrical interfaces, and modulation of the regenerative milieu through cellular, immunomodulatory, or neurotrophic mechanisms has proliferated to enhance the available repertoire of clinically applicable reconstructive options. Despite these advances, patients continue to suffer from functional limitations relating to inadequate cranial nerve regeneration, aberrant reinnervation, or incomplete recovery of neuromuscular function. These shortfalls have profound quality of life ramifications and provide an impetus to further elucidate mechanisms underlying cranial nerve denervation and to improve repair. In this review, we summarize the literature on reconstruction and regeneration of motor cranial nerves following various injury patterns. We focus on seven cranial nerves with predominantly efferent functions and highlight shared patterns of injuries and clinical manifestations. We also present an overview of the existing reconstructive approaches, from facial reanimation, laryngeal reinnervation, to variations of interposition nerve grafts for reconstruction. We discuss ongoing endeavors to promote nerve regeneration and to suppress aberrant reinnervation and the development of synkinesis. Insights from these studies will shed light on recent progress and new horizons in understanding the biomechanics of peripheral nerve neurobiology, with emphasis on promising strategies for optimizing

利用因热源作用而收缩和膨胀的导管研究一阶化学反应和热辐射对幂律Carreau流体热质传输的影响。考虑了以热辐射形式产生热量的流体流动的体积热源和非线性热辐射。采用基于射击简单算法的RK-4方法对径向模式下的质量、动量、能量和物种浓度等基本守恒方程进行了重构和数值求解。考虑粒子的布朗性和热泳性,纳米粒子存在的模型是现象模型。将动量方程与扩展Jaffrey-Hamel问题的Carreau模型组合在一起。不同幂律指数对流体摩擦传热、传热量和传质的影响主要表现在流变性能上,说明剪切增稠型流体比剪切减薄型流体更有效。热传输率在热源处最大,在幂指数最大化时最小。这些研究可能有助于开发一种物理上合理的方法,用于系统化评估收缩/扩张通道中的流体流动和能量使用。

Nitrogen(N) metabolism related enzyme activities,cell uitrastructure and nutrient contents as affected by N level and barley genotype

引用

Journal of Integrative Agriculture 2017年第1期16卷 190-198页

作者： Jawad Munawar Shah syed Asad Hussain Bukhari ZENG Jian-bin QUAN Xiao-yan Essa ali Noor Muhammad ZHANG Guo-ping Department of Agronomy Zijingang Campus Zhejiang University Hangzhou 310058 P.R. China

Development of the new crop cultivars with high yield under low nitrogen （N） input is a fundamental approach to enhance agricultural sustainability, which is dependent on the exploitation of the elite germplasm. In the present study, four barley genotypes （two Tibetan wild and two cultivated）, differing in N use efficiency （NUE）, were characterized for their physiolog- ical and biochemical responses to different N levels. Higher N levels significantly increased the contents of other essential nutrients （P, K, Ca, Fe, Cu and Mn）, and the increase was more obvious for the N-efficient genotypes （ZD9 and XZ149）. The observation of ultrastructure showed that chloroplast structure was severely damaged under low nitrogen, and the two high N efficient genotypes were relatively less affected. The activities of the five N metabolism related enzymes, i.e., nitrate reductase （NR）, glutamine sy＇nthetase （GS）, nitrite reductase （NiR）, glutamate synthase （GOGAT） and glutamate dehydrogenase （GDH） all showed the substantial increase with the increased N level in the culture medium. However the increased extent differed among the four genotypes, with the two N efficient genotypes showing more increase in com- parison with the other two genotypes with relative N inefficiency （HXRL and XZ56）. The current findings showed that a huge difference exists in low N tolerance among barley genotypes, and improvement of some physiological traits （such as enzymes） could be helpful for increasing N utilization efficiency.

In this paper, synthesis and anticancer activities of morpholine hydrazones scaffold（1-17） thoroughly studied. Small series of morpholine hydrazones synthesized by treating 5-morpholinothiophene-2-carbaldehyde with different aryl hydrazides to form morpholine hydrazones scaffold（1-17）. The in vitro anticancer potential of all these compounds was checked against human cancer cell lines like Hep G2（human hepatocellular liver carcinoma） and MCF-7（human breast adenocarcinoma）. Analogs 13 had similar substantial cytotoxic effects towards Hep G2 with IC_（50） value 6.31±1.03μmmol/L when compared with the standard Doxorubicin（IC_（50）value 6.00±0.80μmmol/L）; while compounds 5,8 and 9 showed potent cytotoxicity against MCF-7 with IC_（50） value 7.08±0.42μmmol/L, 1.26±0.34μmmol/L and11.22±0.22μmmol/L respectively when compared with the standard Tamoxifen（IC_（50）= 11.00±0.40μmol/L）. Molecular docking studies also performed to understand the binding interaction.
