| 1 | Bulk and bubble-scale experimental studies of influence of nanoparticles on foam stability显示文摘Influence of silicon oxide(SiO_2) and aluminum oxide(Al_2O_3) nanoparticles on the stability of nanoparticles and sodium dodecyl sulfate(SDS) mixed solution foams was studied at bulk and bubble-scale. Foam apparent viscosity was also determined in Hele-Shaw cell In order to investigate the foam performance at static and dynamic conditions. Results show that the maximum adsorption of surfactant on the nanoparticles occurs at 3 wt% surfactant concentration. Foam stability increases while the foamability decreases with the increasing nanoparticle concentration. However, optimum nanoparticle concentration corresponding to maximum foam stability was obtained at 1.0 wt% nanoparticle concentration for the hydrophilic SiO_2/SDS and Al_2O_3/SDS foams. Foam performance was enhanced with increasing nanoparticles hydrophobicity. Air-foams were generally more stable than CO_2 foams.Foam apparent viscosity increased in the presence of nanoparticles from 20.34 mPa·s to 84.84 mPa·s while the film thickness increased from 27.5 μm to 136 μm. This study suggests that the static and dynamic stability of conventional foams could be improved with addition of appropriate concentration of nanoparticles into the surfactant solution. The nanoparticles improve foam stability by their adsorption and aggregation at the foam lamellae to increase film thickness and dilational viscoelasticity. This prevents liquid drainage and film thinning and improves foam stability both at the bulk and bubble scale. | Nurudeen Yekeen Ahmad Kamal Idris Muhammad A.Manan Ali Mohamed Samin Abdul Rahim Risal Tan Xin Kun | 2017 | Chinese Journal of Chemical Engineering2017，25，3： | 9 |
| 2 | Numerical investigations of asymmetric flow of a micropolar fluid between two porous disks显示文摘Numerical solution is presented for the two-dimensionalflow of a micropolar fluid between two porouscoaxial disks of different permeability for a range of Reynoldsnumber Re (—300 ≤Re < 0) and permeability parameterA (1.0 ≤ A≤2.0). The main flow is superimposed bythe injection at the surfaces of the two disks. Von Karman'ssimilarity transformations are used to reduce the governingequations of motion to a set of non-linear coupled ordinarydifferential equations (ODEs) in dimensionless form. Analgorithm based on the finite difference method is employedto solve these ODEs and Richardson's extrapolation is usedto obtain higher order accuracy. The results indicate that theparameters Re and A have a strong influence on the velocityand microrotation profiles, shear stresses at the disks and theposition of the viscous/shear layer. The micropolar materialconstants c1, c2, c3 have profound effect on microrotationas compared to their effect on streamwise and axial velocityprofiles. The results of micropolar fluids are compared withthe results for Newtonian fluids. | Muhammad Ashraf M.Anwar Kamal K.S.Syed | 2009 | Acta Mechanica Sinica2009，25，6： | 4 |
| 3 | Predicting the presence of adenomatous polyps during colonoscopy with National Cancer Institute Colorectal Cancer Risk-Assessment Tool显示文摘AIM To evaluate the National Cancer Institute(NCI)Colorectal Cancer(CRC)Risk Assessment Tool as a predictor for the presence of adenomatous polyps(AP) found during screening or surveillance colonoscopy.METHODS This is a retrospective single center observational study.We collected data of adenomatous polyps in each colonoscopy and then evaluated the lifetime CRC risk.We calculated the AP prevalence across risk score quintiles,odds ratios of the prevalence of AP across risk score quintiles,area under curves(AUCs)and Youden’s indexes to assess the optimal risk score cut off value for AP prevalence status.RESULTS The prevalence of AP gradually increased throughout the five risk score quintiles:i.e.,27.63%in the first and 51.35%in the fifth quintile.The odd ratios of AP prevalence in the fifth quintile compared to the first and second quintile were 2.76[confidence interval(CI):1.71-4.47]and 2.09(CI:1.32-3.30).The AUC for all patients was 0.62(CI:0.58-0.66).Youden’s Index indicated the optimal risk score cutoff value discriminating AP prevalence status was 3.60.CONCLUSION Patients with the higher NCI risk score have higher risk of AP and subsequent CRC;therefore,measures to increase the effectiveness of CRC detection in these patients include longer withdrawal time,early surveillance colonoscopy,and choosing flexible colonoscopy over other CRC screening modalities. | Hassan Tariq Muhammad Umar Kamal Harish Patel Ravi Patel Muhammad Ameen Shehi Elona Maram Khalifa Sara Azam Aiyi Zhang Kishore Kumar Ahmed Baiomi Danial Shaikh Jasbir Makker | 2018 | World Journal of Gastroenterology2018，24，34： | 3 |
| 4 | Optimization of equitable irrigation water delivery for a large-scale rice irrigation scheme显示文摘Equitable water allocation is essential in an irrigation scheme for obtaining potential crop yields from the entire scheme,especially when water supply is inadequate.An optimization model achieved this goal by coupling an optimal water allocation model with available water supply and irrigation water demand for a river-fed rice irrigation system in Malaysia.This model consists of a paddy field water balance module and an optimization module.The outputs from the module are daily irrigation demand and surface runoff,if there is any.The optimization module consists of an objective function,which minimizes water shortage across the scheme area while maintaining equity in water allocation.This model performs optimization subject to several system constraints,and the decision variable of the model is daily releases or supply to the tertiary canals.Performance of this model remained unaffected under different water supply conditions,and the optimization model reliably examined the effects of alternate water allocation and management rules with field information.It improves efficiency and equity in water allocation with respect to crop growth stages and water shortages rather than simply cutting irrigation supply on a proportional basis to overcome water shortages. | Md Rowshon Kamal Muhammad Iqbal Md Abdul Mojid Mohd Amin Mohd Soom Lai Sai Hin | 2018 | International Journal of Agricultural and Biological Engineering2018，11，5： | 3 |

| 6 | Privacy and security federated reference architecture for Internet of Things显示文摘Physical objects are getting connected to the Internet at an exceptional rate,making the idea of the Internet of Things(IoT)a reality.The IoT ecosystem is evident everywhere in the form of smart homes,health care systems,wearables,connected vehicles,and industries.This has given rise to risks associated with the privacy and security of systems.Security issues and cyber attacks on IoT devices may potentially hinder the growth of IoT products due to deficiencies in the architecture.To counter these issues,we need to implement privacy and security right from the building blocks of IoT.The IoT architecture has evolved over the years,improving the stack of architecture with new solutions such as scalability,management,interoperability,and extensibility.This emphasizes the need to standardize and organize the IoT reference architecture in federation with privacy and security concerns.In this study,we examine and analyze 12 existing IoT reference architectures to identify their shortcomings on the basis of the requirements addressed in the standards.We propose an architecture,the privacy-federated IoT security reference architecture(PF-IoT-SRA),which interprets all the involved privacy metrics and counters major threats and attacks in the IoT communication environment.It is a step toward the standardization of the domain architecture.We effectively validate our proposed reference architecture using the architecture trade-off analysis method(ATAM),an industry-recognized scenario-based approach. | Musab KAMAL Imran RASHID Waseem IQBAL Muhammad Haroon SIDDIQUI Sohaib KHAN Ijaz AHMAD | 2023 | Frontiers of Information Technology & Electronic Engineering2023，24，4： | 1 |

| 15 | Rare sequalae of hiatal hernia causing pancreatitis and hepatitis:A case report显示文摘Hiatal hernia(HH) contents commonly include stomach, transverse colon, small intestine, and spleen but herniation of the pancreas is an extremely rare phenomenon.79-year-old female with multiple comorbidities presented to emergency department with complaints of weight loss for 6 mo and abdominal pain for one day. Physical examination revealed cachectic and dehydrated female and bowel sounds could be auscultated on the right side of chest. Computed tomography of the chest and abdomen revealed interval enlargement of a massive HH,containing stomach and much of the bowel as well as pancreas and distal extrahepatic biliary duct, probably responsible for obstructive effect upon same. There was increased prominence of the pancreas consistent with pancreatitis. There was a large HH causing obstructive effect with dilated biliary system along gall bladder wall edema and pancreatitis. Patient clinical status improved with conservative treatment.HH presenting with acute pancreatitis is a serious diagnostic and therapeutic challenge. The initial management is conservative, even if the abdominal content has herniated to mediastinum. The incentive spirometry can be utilized in the conservative of the large HH. After stabilization of the patient, elective surgical intervention remains the mainstay of the management. Definitive treatment will vary from case to case depending on the acuity of situation and comorbidities. | Muhammad Umar Kamal Ahmed Baiomi Mohamad Erfani Harish Patel | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，3： | 1 |

| 17 | Effects of Tinospora tuberculata leaf methanol extract on seedling growth of rice and associated weed species in hydroponic culture显示文摘The study was conducted to evaluate the responses of rice and rice weed seedlings(barnyardgrass and weedy rice) at the three-leaf stage to Tinospora tuberculata leaf methanol extract(3.12, 6.25 and 12.5 g L–1) under hydroponic culture. It shows that the leaf methanol extract had various degrees effects depending on target plant species and each tested index(biomass, root length, shoot length, transpiration volume, chlorophyll a, chlorophyll b and carotenoid contents). The effective concentration of the leaf extract capable of reducing 50% of rice growth was higher than those of target weed species. Moreover, the root length was more tolerant to leaf methanol extract in comparison to the other plant parameters measured. A greater reduction was observed in chlorophyll a content compared to chlorophyll b and carotenoid. The results revealed that the reduction of transpiration volume closely coincided with the magnitude of growth inhibition of tested plants. Ultra-fast liquid chromatography analysis revealed 11 of 32 peaks in chemical profile, including benzoic acid, caffeic acid, chlorogenic acid, isoorientin, isovitexin, orientin, p-anisic acid, syringic acid, trans-cinnamic acid, trans-ferulic acid, and vitexin have the same retention time with those peaks of the extract. The amount of compounds was present in the range of between 4 817 and 115.5 mg kg–1 dry weight(DW). The concentration-response bioassay of all 11 individual compounds and their equimolar mixture against the seeds of barnyardgrass revealed their contribution in the allelopahic activity of T. tuberculata leaf extract. The examined compounds and their combination exhibited various degrees of growth inhibitory effects on the early growth of barnyardgrass. Therefore, the specific number, concentration, combination and inhibitory activity of bioactive compounds leads to allelopathy activity of T. tuberculata leaves which could be employable directly as a natural herbicide and its growth inhibitor compounds can be used as a template for producing new herbicides. | Farzad Aslani Abdul Shukor Juraimi Muhammad Saiful Ahmad-Hamdani Farahnaz Sadat Golestan Hashemi Md Amirul Alam Md Abdul Hakim Md Kamal Uddin | 2016 | Journal of Integrative Agriculture2016，15，7： | 1 |

| 19 | Advancements in the Development of Various Types of Dye-Sensitized Solar Cells:A Comparative Review显示文摘The global increase in energy demand has resulted in the depletion of non-renewable resources and caused environmental degradation.Consequently,emerging renewable technologies are a potential solution to fulfil energy demand and mitigate the effect of global warming.Low-cost solar energy harvesting technologies are most feasible technologies.Various solar cells technologies have been developed with improved overall performance and conversion effi-ciency.However,due to low cost and a wide range of applications,dye-sensitized solar cells(DSSCs)have been immensely focused on one of the most promising third-generation solar cells.The highest conversion efficiency of DSSC achieved after three decades of research is more than 14%,but the commercialization of this technology is still a challenge.In this review paper,an attempt has been made to present the comparison of different articles published,that gives the in-depth study of recent developments in various types of DSSCs based on architectural assembly and physical appearance.An overview of the limitations and challenges with their possible improvement strategies have also been discussed.This review paper concludes that appropriate selection of electrolytes dramatically affects the performance of DSSC,and quasi-solid-state electrolyte proves to be a better option.Besides,it also concludes that tandem structures are widely agreed with the approach to expand light utilization spectrum for an overall increase in its performance.However,still,the research is required,which could efficiently widen the applications of the DSSCs. | Sandhia Bai A.K.Amirruddin A.K.Pandey M.Samykano Muhammad Shakeel Ahmad Kamal Sharma V.V.Tyagi | 2021 | Energy Engineering2021，118，4： | 0 |
| 20 | Existence and Essence in Mulla Sadra’s Ontology显示文摘This paper examines the relationship between existence and essence in Mulla Sadra’s ontology.It analyses his arguments against the possibility of a real distinction between existence and essence of the existing entities in the world,which is advocated by Ibn Sina,and then explicates how Mulla Sadra after rejecting Ibn Sina’s notion of the real distinction interprets the ontological difference between reality and the possible world by reflecting on his doctrines of the principality of existence(asālat al-wujūd)and the gradation of the reality of existence(tashkīk al-wujūd),rather than existence-essence dichotomy. | Muhammad Kamal | 2019 | Journal of Philosophy Study2019，9，7： | 0 |
