1Wheat straw pretreatment with KOH for enhancing biomethane production and fertilizer value in anaerobic digestion显示文摘Wheat straw biodegradability during anaerobic digestion was improved by treatment with potassium hydroxide(KOH)to decrease digestion time and enhance biomethane production and fertility value.KOH concentrations of1%(K1),3%(K2),6%(K3)and 9%(K4)were tested for wheat straw pretreatment at ambient temperature with a C:N ratio of 25:1.86% of total solids(TS),89% of volatile solids(VS)and 22% of lignocellulose,cellulose and hemicellulose(LCH)(22%)were decomposed effectively with the wheat straw pretreated by 6% KOH.Enhanced biogas production and cumulative biomethane yield of 258 ml·(g VS)^(-1)were obtained increased by 45% and 41%respectively,compared with untreated wheat straw.Pretreated wheat straw digestion also yielded a digestate with higher fertilizer values potassium(138%),calcium(22%)and magnesium(16%).These results show that TS,VS and LCH can be effectively removed from wheat straw pretreated with KOH,improving biodegradability biomethane production and fertilizer value.Muhammad Jaffar Yunzhi Pang Hairong Yuan Dexun Zou Yanping Liu Baoning Zhu Rashid Mustafa Korai Xiujin Li 2016Chinese Journal of Chemical Engineering2016,24,3:11
2A review on application of dielectric barrier discharge plasma technology on the abatement of volatile organic compounds显示文摘Volatile organic compounds(VOCs)released from the waste treatment facilities have become a significant issue because they are not only causing odor nuisance but may also hazard to human health.Non-thermal plasma(NTP)technologies are newly developed methods and became a research trend in recent years regarding the removal of VOCs from the air stream.Due to its unique characteristics,such as rapid response at room temperature,bulk homogenized volume,high reaction efficiency,dielectric barrier discharge(DBD)plasma technology is considered one of the most promising techniques of NTP.This paper reviews recent progress of DBD plasma technology for abatement of VOCs.The principle of plasma generation in DBD and its configurations(electrode,discharge gap,dielectric barrier material,etc.)are discussed in details.Based on previously published literature,attention has been paid on the effect of DBD configuration on the removal of VOCs.Effect of various process parameters such as initial concentration,gas feeding rate,oxygen content and input power on VOCs removal are also considered.Moreover,the role of catalysis and inhibitors in VOCs removal by DBD system are presented.Finally,a modified configuration of the DBD reactor,i.e.double dielectric barrier discharge(DDBD)for the abatement of VOCs is discussed.It was suggested that the DDBD plasma reactor could be used for higher conversion efficiency as well as for avoiding solid residue deposition on the electrode.These depositions can interfere with the performance of the reactor.Wenjing Lu Yawar Abbas Muhammad Farooq Mustafa Chao Pan Hongtao Wang 2019Frontiers of Environmental Science & Engineering2019,13,2:6
3e-antigen-negative chronic hepatitis B in Bangladesh显示文摘BACKGROUND:Bangladesh is a densely populated country where about 10 million people are chronically infected with hepatitis B virus(HBV).The aim of the present study was to evaluate the biochemical,virological and histological characteristics of HBeAg-negative chronic hepatitis B(CHB). METHODS:Patients were included in this study if they were chronically infected with HBV with detectable DNA.The patients who were co-infected with human immunodeficiency virus,hepatitis delta virus or hepatitis C virus,and previously subjected to antiviral treatment,and those with hepatocellular carcinoma were excluded.The study was conducted during the period of January 2001 to December 2007.During this period 2617 patients with CHB were studied.HBeAg-positive cases were included to compare the characteristics.Among them,237 cases underwent liver biopsy. RESULTS:2296 patients(87.7%)were male,with a mean age of 28.9±13.7 years.2375 patients(90.8%)had CHB,and 242(9.2%)were cirrhotic.HBV DNA levels were 7.6±1.5 copies/ml,ALT was 111.3±212.5 U/L,and AST was 91.5± 148.9 U/L.The number of HBeAg-negative CHB cases was 1039(39.7%).HBeAg-negative patients with a lower DNA load were older,and they had more fibrotic changes in the liver than HBeAg-positive patients.The two groups did not differ in necroinflammatory activity,but the former had lower ALT and AST values.Cirrhosis was more common in e-antigen-negative patients.CONCLUSIONS:e-antigen-negative CHB patients are older and have more hepatic fibrosis patients than HBeAg-positive patients,although they have similar necroinflammatory activity.Nooruddin Ahmad Shahinul Alam Golam Mustafa Abul Barkat Muhammad Adnan Rahat Hasan Baig Mobin Khan 2008Hepatobiliary & Pancreatic Diseases International2008,7,4:6
4New molecular method to detect denitrifying anaerobic methane oxidation bacteria from different environmental niches显示文摘The denitrifying anaerobic methane oxidation is an ecologically important process for reducing the potential methane emission into the atmosphere.The responsible bacterium for this process was Candidatus Methylomirabilis oxyfera belonging to the bacterial phylum of NC10.In this study,a new pair of primers targeting all the five groups of NC10 bacteria was designed to amplify NC10 bacteria from different environmental niches.The results showed that the group A was the dominant NC10 phylum bacteria from the sludges and food waste digestate while in paddy soil samples,group A and group B had nearly the same proportion.Our results also indicated that NC10 bacteria could exist in a high p H environment(pH 9.24)from the food waste treatment facility.The Pearson relationship analysis showed that the p H had a significant positive relationship with the NC10 bacterial diversity(p<0.05).The redundancy analysis further revealed that the p H,volatile solid and nitrite nitrogen were the most important factors in shaping the NC10 bacterial structure(p=0.01)based on the variation inflation factors selection and Monte Carlo test(999 times).Results of this study extended the existing molecular tools for studying the NC10 bacterial community structures and provided new information on the ecological distributions of NC10 bacteria.Sai Xu Wenjing Lu Farooq Mustafa Muhammad Yanting Liu Hanwen Guo Ruihong Meng Hongtao Wang 2018Journal of Environmental Sciences2018,30,3:4
5Treatment of prediabetes显示文摘Progression of normal glucose tolerance(NGT) to overt diabetes is mediated by a transition state called impaired glucose tolerance(IGT). Beta cell dysfunction and insulin resistance are the main defects in type 2 diabetes mellitus(type 2 DM) and even normoglycemic IGT patients manifest these defects. Beta cell dysfunction and insulin resistance also contribute to the progression of IGT to type 2 DM. Improving insulin sensitivity and/or preserving functions of beta-cells can be a rational way to normalize the GT and to control transition of IGT to type 2 DM. Loosing weight, for example, improves whole body insulin sensitivity and preserves beta-cell function and its inhibitory effect on progression of IGT to type 2 DM had been proven. But interventions aiming weight loss usually not applicable in real life. Pharmacotherapy is another option to gain better insulin sensitivity and to maintain beta-cell function. In this review, two potential treatment options(lifestyle modification and pharmacologic agents) that limits the IGT-type 2 DM conversion in prediabetic subjects are discussed.Mustafa Kanat Ralph A De Fronzo Muhammad A Abdul-Ghani 2015World Journal of Diabetes2015,6,12:4
6Gene-gene,gene-environment,gene-nutrient interactions and single nucleotide polymorphisms of inflammatory cytokines显示文摘Inflammation plays a significant role in the etiology of type 2 diabetes mellitus(T2DM).The rise in the pro-inflammatory cytokines is the essential step in glucotoxicity and lipotoxicity induced mitochondrial injury,oxidative stress and beta cell apoptosis in T2 DM.Among the recognized markers are interleukin(IL)-6,IL-1,IL-10,IL-18,tissue necrosis factor-alpha(TNF-α),C-reactive protein,resistin,adiponectin,tissue plasminogen activator,fibrinogen and heptoglobins.Diabetes mellitus has firm genetic and very strong environmental influence; exhibiting a polygenic mode of inheritance.Many single nucleotide polymorphisms(SNPs) in various genes including those of pro and antiinflammatory cytokines have been reported as a risk for T2 DM.Not all the SNPs have been confirmed by unifying results in different studies and wide variations have been reported in various ethnic groups.The inter-ethnic variations can be explained by the fact that gene expression may be regulated by gene-gene,gene-environment and gene-nutrient interactions.This review highlights the impact of these interactions on determining the role of single nucleotide polymorphism of IL-6,TNF-α,resistin and adiponectin in pathogenesis of T2 DM.Amina Nadeem Sadaf Mumtaz Abdul Khaliq Naveed Muhammad Aslam Arif Siddiqui Ghulam Mustafa Lodhi Tausif Ahmad 2015World Journal of Diabetes2015,6,4:4
7Structural and optical properties of thermally reduced graphene oxide for energy devices显示文摘Natural intercalation of the graphite oxide, obtained as a product of Hummer's method, via ultra-sonication of water dispersed graphite oxide has been carried out to obtain graphene oxide(GO) and thermally reduced graphene oxide(RGO).Here we report the effect of metallic nitrate on the oxidation properties of graphite and then formation of metallic oxide(MO) composites with GO and RGO for the first time. We observed a change in the efficiency of the oxidation process as we replaced the conventionally used sodium nitrate with that of nickel nitrate Ni(NO_3)_2, cadmium nitrate Cd(NO_3)_2,and zinc nitrate Zn(NO_3)_2. The structural properties were investigated by x-ray diffraction and observed the successful formation of composite of MO–GO and MO–RGO(M = Zn, Cd, Ni). We sought to study the effect on the oxidation process through optical characterization via UV-Vis spectroscopy and Fourier Transform Infrared(FTIR) spectroscopy.Moreover, Thermo Gravimetric Analysis(TGA) was carried out to confirm > 90% weight loss in each process thus proving the reliability of the oxidation cycles. We have found that the nature of the oxidation process of graphite powder and its optical and electrochemical characteristics can be tuned by replacing the sodium nitrate(NaNO_3) by other metallic nitrates as Cd(NO_3)_2, Ni(NO_3)_2, and Zn(NO_3)_2. On the basis of obtained results, the synthesized GO and RGO may be expected as a promising material in antibacterial activity and in electrodes fabrication for energy devices such as solar cell, fuel cell,and super capacitors.Ayesha Jamil Faiza Mustafa Samia Aslam Usman Arshad Muhammad Ashfaq Ahmad 2017Chinese Physics B2017,26,8:3
8Perspectives of Using L-Tryptophan for Improving Productivity of Agricultural Crops: A Review显示文摘Plant growth regulators are biologically active signaling molecules that regulate a number of plant physiological processes. Auxin(indole-3-acetic acid) is an important plant growth regulator and is synthesized within plant tissues through L-tryptophan(L-TRP)-dependent and-independent pathways. It has been found that plants respond to exogenously applied L-TRP due to insufficient endogenous auxin biosynthesis. The exogenous application of L-TRP is highly significant for normal plant growth and development.L-tryptophan is applied through foliar spray, seed priming, and soil application. Soil-applied L-TRP is either directly taken up by plants or metabolized to auxin by soil microbiota and then absorbed by plant roots. Similarly, foliar spray and seed priming with L-TRP stimulates auxin synthesis within plants and improves the growth and productivity of agricultural crops. Furthermore, L-TRP contains approximately 14% nitrogen(N) in its composition, which is released upon its metabolism within a plant or in the rhizosphere and plays a role in enhancing crop productivity. This review deals with assessing crop responses under the exogenous application of L-TRP in normal and stressed environments, mode of action of L-TRP, advantages of using L-TRP over other auxin precursors, and role of the simultaneous use of L-TRP and auxin-producing microbes in improving the productivity of agricultural crops. To the best of our knowledge, this is the first review reporting the importance of the use of L-TRP in agriculture.Ayesha MUSTAFA Muhammad IMRAN Muhammad ASHRAF Khalid MAHMOOD 2018Pedosphere2018,28,1:2
9Heritability and correlation analysis of morphological and yield traits in genetically modified cotton显示文摘Background:Cotton is known for fiber extraction and it is grown in tropical and sub-tropical areas of the world due to having hot weather.Cotton crop has a significant role in GDP of Pakistan.Therefore,the two-years research was conducted to estimate heritability and association among various yield contributing parameters of cotton,i.e.,plant height,number of bolls per plant,number of sympodial branches per plant,seed cotton yield,boll weight,seed index,ginning outturn(GOT),fiber length,fiber strength,and fiber fineness.Results:Association analysis revealed that seed cotton yield had a significant positive correlation with plant height,number of bolls per plant,number of sympodial branches per plant,GOT,staple length and fiber strength.Staple length and fiber strength were negatively linked with each other.Estimates of heritability were high for all of the traits except the number of sympodial branches per plant and boll weight.Conclusion:The parent IUB-222 was found to be the best for plant height,the number of bolls per plant,boll weight,GOT,seed cotton yield,and seed index.The genotypes namely,NIAB-414 and VH-367 were identified as the best parents for fiber length,strength,and fineness.Among the crosses NIAB-414×IUB-222 was the best for the number of bolls per plant,seed index,seed cotton yield and fiber fineness,whereas,the cross of NIAB-414×CIM-632 was good for plant height.The combination of A555×CIM-632 was the best for the number of sympodial branches per plant,boll weight,fiber length,and strength,and VH-367×CIM-632 proved the best for GOT.REHMAN Abdul MUSTAFA Nida DU Xiongming AZHAR Muhammad Tehseen 2020Journal of Cotton Research2020,3,3:2

15Interrelationships between Deformation and Metamorphic Events across the Western Hinterland Zone, NW Pakistan显示文摘Microscopic to mesoscopic structural investigations and foliation intersection axes(FIAs) preserved in porphyroblasts reveal a very complex history of deformation and tectonism within the southwestern part of the western hinterland zone along the northern margin of the Indian plate, NW Pakistan. D_1, D_2, and D_3 related structures in the southwestern part resemble the F_1/F_2, F_3, and F_4 related structures in the northeastern part of the western hinterland zone. These structures developed at the same time through the same changes in the direction of bulk shortening in southwestern and northeastern parts of the western hinterland zone. FIA set 1 indicates NW-SE shortening. The D_2 fabrics, mineral lineations and fold axes indicate E-W shortening. FIA set 2, D_3 fold axes and mineral lineations indicate NNE-SSW shortening. D_3 deformation event is equivalent to the F_4 deformation event in the northeastern part of the western hinterland zone. D_4 fold axes, mineral stretching lineations and axial plane foliation suggest ENE-WSW shortening. The D_4 NNW-SSE fabrics, which formed in the region after the formation of the MMT(main mantle thrust), Khairabad-Panjal thrust fault, Hissartang thrust fault and MBT(main boundary thrust), likely resulted from ENE-WSW bulk shortening related to development of the Hazara-Kashmir syntaxis.Asghar Ali Mustafa Yar Muhammad Asif Khan Shah Faisal 2016Journal of Earth Science2016,27,4:1
16The Effects of Thermal Radiation and Viscous Dissipation on the Stagnation Point Flow of a Micropolar Fluid over a Permeable Stretching Sheet in the Presence of Porous Dissipation显示文摘In this paper,the effects of thermal radiation and viscous dissipation on the stagnation–point flow of a micropolar fluid over a permeable stretching sheet with suction and injection are analyzed and discussed.A suitable similarity transformation is used to convert the governing nonlinear partial differential equations into a system of nonlinear ordinary differential equations,which are then solved numerically by a fourth–order Runge–Kutta method.It is found that the linear fluid velocity decreases with the enhancement of the porosity,boundary,and suction parameters.Conversely,it increases with the micropolar and injection parameters.The angular velocity grows with the boundary,porosity,and suction parameters,whereas it is reduced if the micropolar and injection parameters become larger.It is concluded that the thermal boundary layer extension increases with the injection parameter and decreases with the suction parameter.Muhammad Salman Kausar H.A.M.Al-Sharifi Abid Hussanan Mustafa Mamat 2023Fluid Dynamics & Materials Processing2023,19,1:1

18Foliar application of micronutrients enhances crop stand, yield and the biofortification essential for human health of different wheat cultivars显示文摘Globally about half of the world’s population is under micronutrient malnutrition due to poor quality food intake.To overcome this problem,fortification and biofortification techniques are often used.Biofortification is considered a better option than fortification due to the easy control of nutrient deficiencies present in daily food.This field experiment was conducted to evaluate the effects of foliar application of a micronutrient mixture(MNM)consisting of zinc(Zn),iron(Fe),copper(Cu),manganese(Mn)and boron(B)on yield and flour quality of wheat.The results show the effectiveness of foliar feeding for growth and yield parameters,in addition to the enriching of wheat grains with Zn,Cu,Fe,Mn and B.Compared to the control without foliar feeding,foliar application on wheat crop increased tillering ability,spike length,grain yield and the contents of Zn,Cu,Mn,Fe and B by 21,47,22,22 and 25%in wheat flour,respectively.Therefore,foliar feeding of micronutrients could be an effective approach to enrich wheat grains with essential nutrients for correcting malnutrition.Muhammad Zahir Aziz Muhammad Yaseen Tanveer Abbas Muhammad Naveed Adnan Mustafa Yasir Hamid Qudsia Saeed XU Ming-gang 2019Journal of Integrative Agriculture2019,18,6:1
