| 1 | Systematic Geometric Error Modeling for Workspace Volumetric Calibration of a 5-axis Turbine Blade Grinding Machine显示文摘A systematic geometric model has been presented for calibration of a newly designed 5-axis turbine blade grinding machine.This machine is designed to serve a specific purpose to attain high accuracy and high efficiency grinding of turbine blades by eliminating the hand grinding process.Although its topology is RPPPR(P:prismatic;R:rotary),its design is quite distinct from the competitive machine tools.As error quantification is the only way to investigate,maintain and improve its accuracy,calibration is recommended for its performance assessment and acceptance testing.Systematic geometric error modeling technique is implemented and 52 position dependent and position independent errors are identified while considering the machine as five rigid bodies by eliminating the set-up errors of workpiece and cutting tool.39 of them are found to have influential errors and are accommodated for finding the resultant effect between the cutting tool and the workpiece in workspace volume.Rigid body kinematics techniques and homogenous transformation matrices are used for error synthesis. | Abdul Wahid Khan | 2010 | Chinese Journal of Aeronautics2010，23，5： | 29 |

| 4 | Antiglycation and antioxidation properties of juglans regia and calendula officinalis:possible role in reducing diabetic complications and slowing down ageing显示文摘OBJECTIVE:Accumulation of advanced glycation end products(AGEs) in the body due to the non-enzymatic glycation of proteins and oxidation is associated with aging and diabetes mellitus.In this study we wanted to investigate the antiglycation and antioxidation potential of two medicinal plants:Juglans regia and Calendula officinalis.METHODS:In-vitro investigation was carried out to discover the antiglycation and antioxidation potential of J.regia and C.officinalis.Using an Ultraviolet Double-beam Spectrophotometer,we evaluated the antiglycation property of the crude methanolic extracts of J.regia and C.officinalis by assessing their ability to inhibit the Maillard reaction.Employing the same instrument we also measured the antioxidation potential of these plant extracts using the nitric oxide(NO) free radical-scavenging assay.RESULTS:J.regia had greater antiglycation ability,with a minimum inhibitory concentration(MIC 50) of 28 μg/mL as compared with that of C.officinalis(270 μg/mL).C.officinalis had greater antioxidation potential(26.10,22.07 and 16.06% at 0.5 mg,0.25 mg and 0.125 mg,respectively,as compared with 18.15,16.50 and 16.06% of J.regia,respectively).CONCLUSION:J.regia and C.officinalis inhibited the Maillard reaction and prevented oxidation in-vitro.Hence,the extracts of these plants could have therapeutic uses in curbing chronic diabetic complications and slowing down aging. | Haroon Ahmad Ibrar Khan Abdul Wahid | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 5 |
| 5 | 水下搅拌摩擦焊接:一种具有改善接头性能巨大潜力的搅拌摩擦焊接新方法(英文)显示文摘搅拌摩擦焊接(FSW)是一种固态焊接方法,它能够焊接普通熔焊过程难以焊接的材料;且与熔焊相比,具有高效节能和环境友好的特点。尽管FSW与熔焊相比有更多的优点,但是FSW过程中的热循环会溶解或者粗化热处理铝合金中的沉淀强化相,使接头软化,从而导致其力学性能下降。水下搅拌摩擦焊接(UFSW)是一种可以克服这些缺陷的方法。这种方法适合于在焊接过程中对热敏感的合金,且已广泛用于热处理铝合金。本文对UFSW的研究现状和发展提供了全面的文献综述。与FSW进行对比,从不同角度讨论和总结UFSW的重要性;并对材料流动、温度变化、工艺参数、显微组织和力学性能等基本原理进行详细阐述。结果表明,与FSW相比,UFSW是一种可以改善接头强度的新方法。 | Mohd.Atif WAHID Zahid A.KHAN Arshad Noor SIDDIQUEE | 2018 | Transactions of Nonferrous Metals Society of China2018，28，2： | 4 |
| 6 | Changes in Nutrient-Homeostasis and Reserves Metabolism During Rice Seed Priming:Consequences for Seedling Emergence and Growth显示文摘In this study influence of different seed priming treatments on the nutrient-homeostasis and reserve metabolism during seedling emergence and growth of rice were determined. Seed priming treatments included pre-germination, hydropriming for 48 h, osmohardening with KCl and CaCl2, ascorbate priming and hardening. All treatments shortened the emergence time and enhanced the energy and index of seedling emergence. Seedlings from primed seeds had greater length, number of roots and fresh and dry mass than control. Among the treatments, CaCl2, ascorbate and KCl proved better in enhancing emergence and seedling growth. Seed priming changed the pattern of N and Ca2+ homeostasis both of the seeds and seedlings, which were associated to enhancing α-amylase activity and reducing sugars content. Positive correlations of seedling attributes with nutrient content suggested that as a result of seed priming, most of N and Ca2+ were partitioned to embryo, which enhanced seedling emergence and subsequent growth of rice seedlings. | Muhammad Farooq Shahzad M A Basra Abdul Wahid Nazir Ahmad | 2010 | Agricultural Sciences in China2010，9，2： | 4 |

| 10 | A survey on herbal management of hepatocellular carcinoma显示文摘In this review we outline the different mechanisms mediating hepatocarcinogenesis. We also discuss possible targets of bioactive herbal agents at different stages of hepatocarcinogenesis and highlight their role at each individual stage. We gathered information on the most common herbal prescriptions and extracts thought to be useful in prevention or sensitization for chemotherapy in management of hepatocellular carcinoma (HCC). The value of this topic may seem questionable compared to the promise offered for HCC management by chemotherapy and radiation. However, we would recommend the use of herbal preparations not as alternatives to common chemo /and or radiotherapy, but rather for prevention among atrisk individuals, given that drug/herb interactions are still in need of extensive clarification. The bioactive constituents of various herbs seem to be promising targets for isolation, cancer activity screening and clinical evaluation. Finally, herbal preparations may offer a cost effective protective alternative to individuals known to have a high risk for HCC and possibly other cancers, through maintaining cell integrity, reversingoxidative stress and modulating different molecular pathways in preventing carcinogenesis. | Nabil Mohie Abdel-Hamid Maiiada Hasan Nazmy Ahmed Wahid Mahmoud Michael Atef Fawzy Marco Youssof | 2011 | World Journal of Hepatology2011，3，7： | 3 |
| 11 | Isolation and characterization of marine-derived actinomycetes with cytotoxic activity from the Red Sea coast显示文摘Objective: To isolate and evaluate the cytotoxic activity of different actinomycetes species isolated from the Red Sea coast in Sharm el-Sheikh, Egypt.Methods: Forty actinomycetes strains were isolated from different sediments and seawater samples collected from the Red Sea coast in Egypt. Actinomycetes were recognized by morphological and microscopic examinations. Cell viability and cytotoxicity induced by the crude extracts on breast cancer cell lines MDA-MB-231 were assessed using methylene blue assay. The strains with promising cytotoxic activity were identified by sequencing and amplifying the 16 S r RNA genes. The antibacterial activities of the crude extracts were performed using Kirby–Bauer disc diffusion method.Results: The results indicated that five ethyl acetate extracts exhibited cytotoxicity towards breast cancer cell lines MDA-MB-231. The highest cytotoxic activity was found for the ethyl acetate extracts of EGY2 and EGY39. The isolate EGY3 was identified as a new Streptomyces species, while the actinomycete EGY22 was found to be a member of the genus Nocardiopsis sp. The crude extract of the isolate EGY8 showed slightly high antimicrobial activity against different test microorganisms.Conclusions: The results of the present study reveal that marine sediments of the Red Sea are a potent source of novel species of actinomycetes. The isolates may be useful in discovery of novel bioactive compounds and an important step in the development of microbial natural product research. | Mohamed Saleh Abdelfattah Mohammed Ismail Youssef Elmallah Usama Wahid Hawas Lamia Taha Abou El-Kassema Mennat Allah Gamal Eid | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，8： | 3 |
| 12 | Removal of phenol by activated carbons prepared from palm oil mill effluent sludge显示文摘The study was attempted to produce activated carbons from palm oil mil l effluent (POME) sludge. The adsorption capacity of the activated carbons produ ced was evaluated in aqueous solution of phenol. Two types of activation were fo llowed, namely, thermal activation at 300, 500 and 800℃, and physical activatio n at 150℃ (boiling treatment). A control (raw POME sludge) was used to compare the adsorption capacity of the activated carbons produced. The results indicated that the activation temperature of 800℃ showed maximum absorption capacity by the activated carbon (POME 800) in aqueous solution of phenol. Batch adsorption studies showed an equilibrium time of 6 h for the activated carbon of POME 800. It was observed that the adsorption capacity was higher at lower values of pH (2 —3) and higher value of initial concentration of phenol (200—300 mg/L). The eq uilibrium data were fitted by the Langmuir and Freundlich adsorption isotherms. The adsorption of phenol onto the activated carbon POME 800 was studied in terms of pseudo- first and second order kinetics to predict the rate constant and equ ilibrium capacity with the effect of initial phenol concentrations. The rate of adsorption was found to be better correlation for the pseudo-second order kineti cs compared to the first order kinetics. | Md. Zahangir ALAM Suleyman A. MUYIBI Mariatul F.

| 13 | Characterization of Nitrogen Uptake Pattern in Malaysian Rice MR219 at Different Growth Stages Using ^(15)N Isotope显示文摘Nitrogen(N) use efficiency is usually less than 50%, and it remains a major problem in rice cultivation. Controlled release fertilizer(CRF) technology is one of the well-known efforts to overcome this problem. The efficiency of CRF, however, is very much dependent on the timing of nutrient release. This study was conducted to determine the precise time of N uptake by rice as a guideline to develop efficient CRF. Fertilizer N uptake by rice at different growth stages was investigated by using 15 N isotopic technique. Rice was planted in pots, with 15 N urea as N source at the rate of 120 kg/hm2. Potassium and phosphorus were applied at the same rate of 50 kg/hm2. Standard agronomic practices were employed throughout the growing periods. Rice plants were harvested every two weeks until maturation at the 14 th week and analyzed for total N and 15 N content. Nitrogen derived from fertilizer was calculated. Total N uptake in plants consistently increased until the 11 th week. After that, it started to plateau and finally declined. Moreover, N utilization by rice plants peaked at 50%, which occurred during the 11 th week after transplanting. N derived from fertilizer in rice plants were in the range of 18.7% to 40.0% in all plant tissues. The remaining N was derived from soil. Based on this study, N release from CRF should complete by the 11 th week after planting to ensure the maximum fertilizer N uptake by rice plants. Efficient CRF should contribute to higher N derived from fertilizer which also resulted in a higher total N uptake by rice plants, increasing the potential of rice to produce higher yield while at the same time of reducing loss. | Mohammad Mu'az HASHIM Mohd Khanif YUSOP Radziah OTHMAN Samsuri Abdul WAHID | 2015 | Rice science2015，22，5： | 3 |

| 15 | Effect of climate factors on the incidence of hand, foot, and mouth disease in Malaysia: A generalized additive mixed model显示文摘Climate change is one of the critical determinants affecting life cycles and transmission of most infectious agents,including malaria,cholera,dengue fever,hand,foot,and mouth disease(HFMD),and the recent Corona-virus pandemic.HFMD has been associated with a growing number of outbreaks resulting in fatal complications since the late 1990s.The outbreaks may result from a combination of rapid population growth,climate change,socioeconomic changes,and other lifestyle changes.However,the modeling of climate variability and HFMD remains unclear,particularly in statistical theory development.The statistical relationship between HFMD and climate factors has been widely studied using generalized linear and additive modeling.When dealing with time-series data with clustered variables such as HFMD with clustered states,the independence principle of both modeling approaches may be violated.Thus,a Generalized Additive Mixed Model(GAMM)is used to investigate the relationship between HFMD and climate factors in Malaysia.The model is improved by using a first-order autoregressive term and treating all Malaysian states as a random effect.This method is preferred as it allows states to be modeled as random effects and accounts for time series data autocorrelation.The findings indicate that climate variables such as rainfall and wind speed affect HFMD cases in Malaysia.The risk of HFMD increased in the subsequent two weeks with rainfall below 60 mm and decreased with rainfall exceeding 60 mm.Besides,a two-week lag in wind speeds between 2 and 5 m/s reduced HFMD's chances.The results also show that HFMD cases rose in Malaysia during the inter-monsoon and southwest monsoon seasons but fell during the northeast monsoon.The study's outcomes can be used by public health officials and the general public to raise awareness,and thus,implement effective preventive measures. | Nurmarni Athirah Abdul Wahid Jamaludin Suhaila Haliza Abd.Rahman | 2021 | Infectious Disease Modelling2021，6，1： | 2 |
| 16 | Mycorrhiza and Phosphate Solubilizing Bacteria:Potential Bioagents for Sustainable Phosphorus Management in Agriculture显示文摘Phosphorus(P)is a critical nutrient that plays an essential role in improving soil fertility for optimum plant growth and productivity.It is one of the most deficient macro-nutrients in agricultural soils after nitrogen and is considered inadequate for plant growth and production.To P availability in soils,the farmers are applying huge amounts of synthetic P fertilizers that adversely affect the wider environment,groundwater,soil fertility and microbial population.Many beneficial microbes are known to release and supply soluble P for improving growth and yield of a variety of plants in a sustainable manner in P deficient soils.Thus,inoculation of these microbes,including arbuscular mycorrhizal fungi(AMF)and phosphate solubilizing bacteria(PSB)to soil to enhance crop production without harming the environment,is an alternative approach to chemical fertilizers.The combined role of AMF and PSB in P solubilization is not well understood and the application and mode of action of these microbial groups are often naive due to variation in the environment.Therefore,the current review article would develop a better understanding of the interactive role and mechanisms of AMF and PSB in improving P availability from both organic and inorganic sources in a sustainable crop production system.Finally,the current review would loop out further avenues for researchers interested to commercially produce effective AMF and PSB-based biofertilizers for sustainable management of phosphorus over a wide range of agricultural crops worldwide. | Fazli Wahid Muhammad Sharif Shah Fahad Amjad Ali Muhammad Adnan Rafiullah Shah Saud Subhan Danish Muhammad Arif Ali Niaz Ahmed Hüseyin Arslan Doğan Arslan Murat Erman Ayman EL Sabagh Fatemeh Gholizadeh Rahul Datta | 2022 | Phyton-International Journal of Experimental Botany2022，91，2： | 2 |

| 19 | Numerical evaluation of new Austrian tunneling method excavation sequences: A case study显示文摘The main aspects that require attention in tunnel design in terms of safety and economy are the precise estimation of probable ground conditions and ground behavior during construction. The variation in rock mass behavior due to tunnel excavation sequence plays an important role during the construction stage.The purpose of this research is to numerically evaluate the effect of excavation sequence on the ground behavior for the Lowari tunnel project, Pakistan. For the tunnel stability, the ground behavior observed during the actual partial face excavation sequence is compared with the top heading and bench excavation sequence. For this purpose, the intact rock parameters are used along with the characterization of rock mass joints related parameters to provide input for numerical modelling via FLAC 2D. The in-situ stresses for the numerical modelling are obtained using empirical equations. From the comparison of the two excavation sequences, it was observed that the actual excavation sequence used for Lowari tunnel construction utilized more support than the top heading and bench method. However, the actual excavation sequence provided good results in terms of stability. | Hafeezur Rehman Abdul Muntaqim Naji Wahid Ali Muhammad Junaid Rini Asnida Abdullah Han-kyu Yoo | 2020 | International Journal of Mining Science and Technology2020，30，3： | 2 |
