| 2 | Experimental study on the meso-scale milling of tungsten carbide WC-17.5Co with PCD end mills显示文摘Tungsten carbide is a material that is very difficult to cut,mainly owing to its extreme wear resistance.Its high value of yield strength,accompanied by extreme brittleness,renders its machinability extremely poor,with most tools failing.Even when cutting with tool materials of the highest quality,its mode of cutting is mainly brittle and marred by material cracking.The ductile mode of cutting is possible only at micro leveIs of depth of cut and feed rate.This study aims to investigate the possibility of milling the carbide material at a meso-scale using polycrystaline diamond(PCD)end mills.A series of end milling experiments were performed to study the effects of cutting speed,feed per tooth,and axial depth of cut on performance measures such as cutting forces,surface roughness,and tool wear.To characterize the wear of PCD tools,a new approach to measuring the level of damage sustained by the faces of the cutter's teeth is presented.Analyses of the experimental data show that the effects of all the cutting parameters on the three performance measures are significant.The major damage mode of the PCD end mills is.found to be the intermittent micro-chipping.The progress of tool damage saw a long,stable,and steady period sandwiched between two short,abrupt,and intermittent periods.Cutting forces and surface roughness are found to rise with increments in the three cutting parameters,although the latter shows signs of reduction during the initial increase in cutting speed only.The results of this study find that an acceptable surface quality(average roughness Ra<0.2μm)and tool life(cutting length L>600mm)can be obtained under the conditions of the given cutting parameters.It indicates that milling with PCD tools at a meso-scale is a suitable machining method for tungsten carbides. | Wei Zhao Asif Iqbal Ding Fang Ning He Qi Yang | 2020 | Advances in Manufacturing2020，8，2： | 2 |
| 3 | Morphological and Genetical Variability among Rhizoctonia solani Isolates Causing Sheath Blight Disease of Rice显示文摘Eighteen isolates of Rhizoctonia solani collected from infected rice plants in four different locations of Bangladesh were studied by using morphological characters and molecular markers. Anastomosis study with a reference isolate confirmed that all the isolates belonged to R. solani. Significant variation was observed in sclerotial size, shape and distribution. Un-weighted pair group method with arithmetic mean dendrogram constructed based on the Gower's general similarity coefficient showed that these isolates were grouped into four clusters at the 0.68 similarity coefficent according to morphological characters. Cluster I was a major cluster consisting of 13 isolates, while clusters Ⅱ to Ⅳ consisted of 1 or 2 isolates. Analyses by variable number of tandem repeat and amplified fragment length polymorphism markers showed that the isolates were grouped into five and three clusters at a similarity coefficient of 0.64 and 0.69, respectively. Although most of the variability was found between isolates from different regions as expected, significant variation was observed within the isolates collected from similar agro-ecological regions. Our results suggest the presence of different races of R. solani within the same local geographic regions. | Zakiah Rahman MONI Md Ansar ALI Md Shahidul ALAM Md Asif RAHMAN Md Rejwan BHUIYAN Md Salim MIAN Khandakar Md IFTEKHARUDDAULA Md Abdul LATIF Mohammad Ashik Iqbal KHAN | 2016 | Rice science2016，23，1： | 2 |
| 4 | 腐植酸产品特性及其对真菌和植物生长的影响显示文摘天然腐植酸主要来自风化煤和褐煤等,其产品主要有Pak腐植酸盐、腐植酸盐肥料、PakHumax、Hum-kara和Humide等,它们在使用之前必须了解其功效。本研究比较了4种腐植酸肥料的理化性质、光学特性以及对小麦(栽培品种Sehr)、绿豆(绿豆-54)、玉米(C-12)和田菁种子萌发和生长的影响,同时研究了它们对4种真菌的影响。4种腐植酸肥料的含水量为52%~71.11%,溶解度为30.2%~98.2%,密度为1.67~4.17g/mL,2%腐植酸肥料水溶液pH值为5.39~10.11,EC值为3.140~1.143mS/cm。4种腐植酸肥料的碳含量为22.95%~36.56%、氮含量为0.658%~1.183%,相应的C/N比为30.91~44.16。将4种腐植酸肥料用0.1mol/LNaOH溶液溶解,分离获得腐植酸和黄腐酸,按含碳量计算,含碳量40.3%~77.5%的为腐植酸,含碳量22.5%~59.7%的为黄腐酸。对腐植酸在400nm、500nm、600nm和700nm下的光学性质进行了研究,并对465nm和665nm条件下的吸光度进行测量,计算其比值E4/E6(即消光系数)。结果表明,E4/E6比值变化在3.64~5.48之间,且光密度随着波长的增加而降低,与腐殖质的碳含量具有显著相关性。供试的4株真菌中,根据菌落直径观察,Tricho-dermaharzianum,T.hamatum和Alternariaalternate3种真菌在0.025%腐植酸培养基上生长最好。4种腐植酸肥料对小麦、玉米、绿豆种子萌发都有抑制作用,但对田菁种子萌发具有促进作用;对小麦和玉米的根具有促进生长的作用,同时可以提高小麦和玉米芽的干物质含量,而对绿豆和田菁没有影响。研究发现,巴基斯坦市场上销售的腐植酸肥料差异很大,为保障使用者的利益,对这些肥料进行质量监测十分必要。 | Asma Lodhi Shermeen Tahir Zafar Iqbal Ansar Mahmood Muhammad Akhtar Tariq Mahmood Qureshi Muhammad Yaqub Asif Naeem 董心亮 管天玉 林启美 | 2014 | 腐植酸2014，，2： | 2 |

| 6 | SiC_p及Al_2O_(3w)增强铸态混杂金属基复合材料的疲劳裂纹扩展机理(英文)显示文摘研究了一种SiCp及Al2O3w增强铸态混杂金属基复合材料(MMC)的疲劳裂纹扩展(FCG)机理,同时对比研究了Al2O3w增强铸态金属基复合材料和铸态铝合金的疲劳裂纹扩展机理。在研究近临界和裂纹稳定扩展区域的疲劳裂纹扩展(FCG)机理时,发现混杂MMC的临界应力强度因子?Kth值高于其他两种材料的?Kth值,说明应力强度因子?K值较低时混杂MMC可以更好地抵抗裂纹扩展。随着?K值的降低,两种MMC在近临界区域显示出相似的FCG机理,即主要由增强相–基体界面的剥离控制,随后由铝基体中空隙的形核与合并控制;在裂纹稳定或中等扩展区域,?K值较高时FCG除了受界面上周期性裂纹扩展引起的增强相–基体界面剥离的影响之外,还显著受到铝基体中疲劳条带的影响。此外,在高?K值下,因为局部失稳断裂机制,可见铝基体中空隙的形核与合并以及SiCp和Al2O3w中的穿晶断裂。对于铸态铝合金,在低?K值下,FCG主要受空隙的形核与合并所控制;在高?K值下,FCG主要受铝晶粒的疲劳条带控制,随后受Si团簇中空隙的形核与合并控制。 | AKM Asif IQBAL Yoshio ARAI Wakako ARAKI | 2014 | Transactions of Nonferrous Metals Society of China2014，24，S1： | 2 |

| 16 | Application of Ceramic Film as Means of Lubrication for Forming of TiSheet in a Highly Localized Deformation Process显示文摘Incremental forming is a novel die-less sheet forming process. There is a need for special means to retain lubricant at the tool/sheet interface during forming. To fulfill the stated aim, a porous ceramic film was developed on pure Tisubstrate, and it was done through an electrochemical depsition process known as plasma electrolytic oxidation. The film with preferred pore size could be realized after several attempts by varying the processing parameters. In order to characterize the film, a variety of tests including microstructure, film-substrate bond strength and tribological properties tests were conducted. On-job performance of the film was also examined by forming Ticomponents employing a range of forming conditions. It was found that the proposed method of lubrication was effective, and the plasma eletrolytic oxidation process can be employed to fabricate films on pure Tisheet to provide means of lubrication during incremental forming. | GHULAM Hussain ASIF Iqbal | 2014 | Journal of Wuhan University of Technology(Materials Science)2014，29，5： | 1 |
| 17 | Optimization of Abrasive Water Jet Cutting of Ductile Materials显示文摘Full factorial design of experiments was developed in order to investigate the effects of jet pressure, abrasive mixing rate, cutting feed, and plate thickness upon three response variables, surface finish of cutting wear zone, percentage proportion of striation free area, and maximum width of cut. The set of sixteen experiments was performed on each of the following two ductile materials: AISI 4340 (high strength low alloy steel, hardened to 49HRc) and Aluminum 2219. Analysis of Variance (ANOVA) was performed on experimental data in order to determine the significance of effects of different parameters on the performance measures. It was found that cutting feed and thickness were highly influential parameters, while abrasive mixing rate is influential upon surface roughness only. Strong interaction was found between jet pressure and workpiece material. Multi-criteria numerical optimization was performed in order to simultaneously maximize/minimize different combinations of performance measures. | Asif IQBAL Naeem U DAR Ghulam HUSSAIN | 2011 | Journal of Wuhan University of Technology(Materials Science)2011，26，1： | 1 |
| 18 | A multi-purpose National Forest Inventory in Bangladesh:design,operationalisation and key results显示文摘Background:National forest inventory and forest monitoring systems are more important than ever considering continued global degradation of trees and forests.These systems are especially important in a country like Bangladesh,which is characterised by a large population density,climate change vulnerability and dependence on natural resources.With the aim of supporting the Government’s actions towards sustainable forest management through reliable information,the Bangladesh Forest Inventory(BFI)was designed and implemented through three components:biophysical inventory,socio-economic survey and remote sensing-based land cover mapping.This article documents the approach undertaken by the Forest Department under the Ministry of Environment,Forests and Climate Change to establish the BFI as a multipurpose,efficient,accurate and replicable national forest assessment.The design,operationalization and some key results of the process are presented.Methods:The BFI takes advantage of the latest and most well-accepted technological and methodological approaches.Importantly,it was designed through a collaborative process which drew from the experience and knowledge of multiple national and international entities.Overall,1781 field plots were visited,6400 households were surveyed,and a national land cover map for the year 2015 was produced.Innovative technological enhancements include a semi-automated segmentation approach for developing the wall-to-wall land cover map,an object-based national land characterisation system,consistent estimates between sample-based and mapped land cover areas,use of mobile apps for tree species identification and data collection,and use of differential global positioning system for referencing plot centres.Results:Seven criteria,and multiple associated indicators,were developed for monitoring progress towards sustainable forest management goals,informing management decisions,and national and international reporting needs.A wide range of biophysical and socioeconomic data were collected,and in some cases integrated,for estimating the indicators.Conclusions:The BFI is a new information source tool for helping guide Bangladesh towards a sustainable future.Reliable information on the status of tree and forest resources,as well as land use,empowers evidence-based decision making across multiple stakeholders and at different levels for protecting natural resources.The integrated socioeconomic data collected provides information about the interactions between people and their tree and forest resources,and the valuation of ecosystem services.The BFI is designed to be a permanent assessment of these resources,and future data collection will enable monitoring of trends against the current baseline.However,additional institutional support as well as continuation of collaboration among national partners is crucial for sustaining the BFI process in future. | Matieu Henry Zaheer Iqbal Kristofer Johnson Mariam Akhter Liam Costello Charles Scott Rashed Jalal Md.Akhter Hossain Nikhil Chakma Olaf Kuegler Hossain Mahmood Rajib Mahamud Mohammad Raqibul Hasan Siddique Khaled Misbahuzzaman Mohammad Main Uddin Mohammed Al Amin Farid Uddin Ahmed Gael Sola Md.Baktiar Siddiqui Luca Birigazzi Mahmudur Rahman Ilias Animon Saimunnahar Ritu Laskar Muqsudur Rahman Aminul Islam Heather Hayden Frida Sidik Mondal Falgoonee Kumar Rakibul Hassan Mukul Hossain Nishad Ariful Hoque Belal Asif Reza Anik Abdul Khaleque Md.Shaheduzzaman Syed Shahadat Hossain Tariq Aziz Md.Tauhidor Rahaman Ruhul Mohaiman Patrick Meyer Purnata Chakma A.Z.M.Manzoor Rashid Sourav Das Shrabanti Hira Mohammed Jashimuddin Mohammad Mahfuzur Rahman Karl Wurster Sarder Nasir Uddin Abul Kalam Azad S.M.Zahirul Islam Laurent Saint-André | 2021 | Forest Ecosystems2021，8，1： | 0 |
| 19 | Analysis of Classical Encryption Techniques in Cloud Computing显示文摘Cloud computing has become a significant computing model in the IT industry. In this emerging model,computing resources such as software, hardware, networking, and storage can be accessed anywhere in the world on a pay-per-use basis. However, storing sensitive data on un-trusted servers is a challenging issue for this model. To guarantee confidentiality and proper access control of outsourced sensitive data, classical encryption techniques are used. However, such access control schemes are not feasible in cloud computing because of their lack of flexibility, scalability, and fine-grained access control. Instead, Attribute-Based Encryption(ABE) techniques are used in the cloud. This paper extensively surveys all ABE schemes and creates a comparison table for the key criteria for these schemes in cloud applications. | Muhammad Yasir Shabir Asif Iqbal Zahid Mahmood Ata Ullah Ghafoor | 2016 | Tsinghua Science and Technology2016，21，1： | 0 |
| 20 | Sustainable food industrial waste management through single cell protein production and characterization of protein enriched bread显示文摘Production of single cell protein(SCP)from food waste is one of the promising approaches for excellent waste management.In the present study,SCP was produced through submerged fermentation using selected food wastes(banana peel,citrus peel,carrot pomace and potato peel).During process optimization,combinations of various temperature and nitrogen sources were studied for optimum SCP yield(g/100g).The results indicated that maximum SCP yield was obtained at 30℃ for 7 days on potato peels,whereas citrus and banana peels exhibited the lowest SCP yield at the same process conditions.The SCP compositional analysis indicated that the amount of non-essential amino acids was significantly higher than wheat flour.Furthermore,SCP enriched bread was prepared by adding SCP at different concentrations(0,4,8,and 12%).The organoleptic properties indicated that SCP addition up to 4%was acceptable to prepare protein enriched bread.Thus,SCP may be effectively used for food waste management and food security. | Muhammad Kashif Iqbal Khan Muhammad Asif Zafar Ullah Razzaq Akmal Nazir Abid Aslam Maan | 2022 | Food Bioscience2022，46，2： | 0 |
