| 1 | Action Mechanisms of Arbuscular Mycorrhizal Fungi in Phosphorus Uptake by Capsicum annuum L.显示文摘A pot experiment was conducted to investigate the action mechanisms of arbuscular mycorrhizal (AM) fungi in phosphorus (P) uptake of Capsicum annuum L.in a sterilized fossil Oxisol.Three P levels of 0,10 and 200 mg kg-1 soil (P0,P10 and P200,respectively) without and with AM fungal inoculation were applied as Ca(H2PO4)2·H2O.Shoot dry matter yields and shoot P uptake increased significantly (P > 0.05) by the inoculation of AM fungi at P0 and P10.Root length and P concentration in soil solution increased with the inoculation of AM fungi but the root:shoot ratio decreased or remained constant.Around 50% roots of inoculated plants were infected by AM and the external hyphae amounted to 20 m g-1 soil at P10 and P200.The hyphae surface area of the infected root cylinder amounted to 11 and 2 cm-2 cm-2 root at P0 and P10,respectively.The increased P uptake of inoculated plants was mainly because of an up to 5 times higher P influx of the infected root.Model calculations showed that the root alone could not have achieved the measured P influx in both infected and non-infected roots.But the P influx for hyphae calculated by the model was even much higher than the measured one.The P uptake capacity of hyphae introduced in the model was too high.Model calculations further showed that the depletion zone around roots or hyphae was very narrow.In the case of the root only 7% of the soil volume would contribute P to the plant,while in the case of hyphae it would be 100%.The results together with the model calculations showed that the increased P uptake of AM inoculated plants could be explained partly by the increased P concentration in the soil solution and by the increased P absorbing surface area coming from the external hyphae. | M.SHARIF N.CLAASSEN | 2011 | Pedosphere2011，21，4： | 10 |
| 2 | 过瘤胃蛋白和氨基酸对奶牛、绵羊干物质采食量、消化率和生长性能的影响显示文摘数量充足和配比合理的营养对家畜生产性能起着决定性作用,其中蛋白质是动物生长发育、繁殖性能的主要限制因素之一。蛋白质的种类和水平决定着动物机体组成及日粮中必需氨基酸的供应。对反刍动物来说,蛋白质的作用是双方面,既要满足瘤胃厌氧微生物发酵的需要,又要满足动物成长的营养需要。然而,由于瘤胃的发酵作用,日粮中绝大多数蛋白质在瘤胃内被降解(称为瘤胃降解蛋白,RDP),只有小部分能通过瘤胃在小肠内吸收(称为非瘤胃降解蛋白,RUP),因此用于厌氧合成微生物蛋白的RDP以及RUP的种类决定了反刍动物日粮和机体必需氨基酸的利用率。微生物蛋白和过瘤胃蛋白决定了高产动物日粮中必需氨基酸的供应。因此,饲喂过瘤胃蛋白和氨基酸被认为是满足反刍动物生理以及生产需要的有效方法。文章综述了过瘤胃蛋白、过瘤胃赖氨酸和过瘤胃蛋氨酸在反刍动物上的应用,以及对奶牛、绵羊干物质采食量、消化率、生产性能影响的研究。蛋白质是反刍动物重要的限制性营养,由RDP和RUP组成。瘤胃微生物通过将RDP降解成小肽、氨基酸和氨等来合成微生物蛋白,其数量主要受日粮中瘤胃发酵率的制约。因此,RDP和RUP或氨基酸的供应对于满足反刍动物营养需要非常重要,尤其是对于饲喂低水平日粮的反刍动物。添加瘤胃保护蛋白和瘤胃保护氨基酸(特别是赖氨酸和蛋氨酸)能提高奶牛、绵羊的干物质采食量和消化率。同时,还能够提高生长性能、繁殖效率和产奶量。不管是单独添加,还是与赖氨酸同时添加,如果蛋氨酸的添加量大于肠道的可消化吸收量时,则有可能会产生负面影响。在奶牛泌乳早期的低蛋白水平日粮中添加蛋氨酸,能避免奶牛长期的不良反应。总而言之,反刍动物在低营养水平下添加瘤胃保护蛋白质和氨基酸,能提高饲料采食量、消化率以及生长性能。 | Ali C.S.

| 5 | Characterization of a Mineral Synthesized by Availing Silica from Plant Source显示文摘Rice husk was used to prepare the silica of amorphous nature being several times more reactive than that obtained from the mineral kingdom. Number of rice husk batches were pyroprocessed under varying time-temperature parameters for this purpose. The ash resulting from a batch pyroprocessed at 500℃ for 8 h contained 92.01% silica. It was upgraded to 98.50% by applying physicochemical purification procedures. The mineral, wollastonite (CaSiO3), was synthesized from thus prepared silica and limestone containing 55.91% CaO. Solid state reaction, between CaO and SiO2 was attempted at different temperatures in the presence of a mineralizer. The sintering temperature,for affecting the said synthesis, was ranged between 900℃ to 1300℃ with the steps of 100℃. Specific chemical analysis techniques were applied to determine the effectiveness of carried out reaction and promising batches were subsequently subjected to XRD investigations. The produced mineral was also characterized regarding its physical properties like: colour, hardness, melting point and specific gravity. Percent yield of the produced wollastonite was also estimated and compared with that of obtained by other researchers who synthesized it by using silica from mineral kingdom. Batches sintered at 1200℃ and 1300℃ for 1 h showed the overall best results. | M.Sharif Nizami | 2003 | Journal of Materials Science & Technology2003，19，6： | 1 |
| 6 | Phase Space Analysis and Anisotropic Universe Model in f(T) Gravity显示文摘In this paper, we study the stability of locally rotationally symmetric(LRS) Bianchi I universe model in f(T) gravity through phase space analysis. We assume that the f(T) gravity can be treated as effective dark energy behaving like perfect fluid, and suggest that there are interactions between pressureless matter as well as dark energy.We construct the corresponding autonomous system of equations to check the stability of the model for non phantom,vacuum and phantom phases. It is concluded that critical points remain more stable in phantom phase as compared to non phantom and vacuum cases. Finally, we discuss the cosmological behavior of the model through some cosmological parameters. | M.Sharif Saima Jabbar | 2015 | Communications in Theoretical Physics2015，63，2： | 0 |

| 8 | Phantom Energy Accretion by a Stringy Charged Black Hole显示文摘We investigate the dynamical behavior of phantom energy near a stringy magnetically charged black hole.For this purpose,we derive equations of motion for steady-state spherically symmetric flow of phantom energy onto the stringy magnetically charged black hole.It is found that phantom energy accreting onto a black hole decreases its mass.Further,the location of the critical points of accretion is explored,which yields a mass to charge ratio.This ratio implies that accretion process cannot transform a black hole into an extremal black hole or a naked singularity,hence cosmic censorship hypothesis remains valid here. | M.Sharif G.Abbas | 2012 | Chinese Physics Letters2012，29，1： | 0 |
| 9 | Singularities of noncompact charged objects显示文摘We formulate a model for noncompact spherical charged objects in the framework of noncommutative field theory.The Einstein-Maxwell field equations are solved with charged anisotropic fluid.We choose matter and charge densities as functions of the two parameters,instead of defining these quantities in terms of the Gaussian distribution function.It is found that the corresponding densities and the Ricci scalar are singular in origin,whereas the metric is nonsingular,indicating a spacelike singularity.The numerical solution of the horizon equation implies that there are two or one or no horizon(s),depending on the mass.We also evaluate the Hawking temperature and find that a black hole with two horizons is evaporated to an extremal black hole with one horizon. | M.Sharif G.Abbas | 2013 | Chinese Physics B2013，22，3： | 0 |
| 10 | Static Axially Symmetric Models and Structure Scalars in Self-Interacting Brans–Dicke Gravity显示文摘This paper investigates static axially symmetric models in self-interacting Brans–Dicke gravity. We discuss physically feasible sources of models, derive field equations as well as evolution equations from Bianchi identities and construct structure scalars. Using these scalars and evolution equations, the inhomogeneity factors of the system are evaluated. It is found that structure scalars related to double dual of Riemann tensor control the density inhomogeneity.Finally, we obtain exact solutions of homogenous isotropic and inhomogeneous anisotropic spheroid models. It turns out that homogenous solutions reduce to Schwarzschild type interior solutions for a spherical case. We conclude that homogenous models involve homogenous distribution of scalar field whereas inhomogeneous correspond to inhomogeneous scalar field. | M.Sharif Rubab Manzoor | 2017 | Communications in Theoretical Physics2017，67，7： | 0 |

We discuss scale factors as well as deceleration parameter in dark energy dominated era for different bulk viscosity models. The occurrence of big-rip singularity is also examined. It is concluded that expansion is faster when bulk viscosity is proportional to Hubble parameter as compared to other models. | M.Sharif Aisha Siddiqa | 2018 | Communications in Theoretical Physics2018，69，5： | 0 |
| 12 | Shearfree Spherically Symmetric Fluid Models显示文摘We attempt to discover some exact analytical models of the spherically symmetric spacetime of collapsing fluid under shearfree conditions.Two types of solution are considered:one is to impose a condition on the mass function,while the other is to restrict the pressure.We obtain five exact models in total,and some of them satisfy the Darmoie conditions. | M.Sharif Z.Yousaf | 2012 | Chinese Physics Letters2012，29，5： | 0 |
| 13 | Evolution of Dissipative Anisotropic Expansion-Free Axial Fluids显示文摘A general study of non-static restricted class of axial system with anisotropic dissipative expansion-free fluid under geodesic condition is carried out. It is found that expansion-free model must be dissipative under geodesic condition to preserve axial symmetry. We also investigate this system without geodesic condition. Finally, the role of dissipation is explored via transport equation. | M.Sharif Zunaira Nasir | 2015 | Communications in Theoretical Physics2015，，8： | 0 |
| 14 | Tidal Forces in Dyonic Reissner-Nrdstrom Black Hole显示文摘This paper investigates the tidal as well as magnetic charge effects produced in dyonic Reissner-Nordstr¨om black hole.We evaluate Newtonian radial acceleration using radial geodesics for freely falling test particles.We establish system of equations governing radial and angular tidal forces using geodesic deviation equation and discuss their solutions for bodies falling freely towards this black hole.The radial tidal force turns out to be compressing outside the event horizon whereas the angular tidal force changes sign between event and Cauchy horizons unlike Schwarzschild black hole.The radial geodesic component starts decreasing in dyonic Reissner-Nordstr¨om black hole unlike Schwarzschild case.We conclude that magnetic charge strongly affects the radial as well as angular components of tidal force. | M.Sharif Lubna Kousar | 2018 | Communications in Theoretical Physics2018，69，3： | 0 |
| 15 | Effects of f(R) Model on Dynamics of Axial Shear-Free Dissipative Fluids显示文摘We present a general analysis on non-static axial system with dissipative shear-free anisotropic fluid using polynomial inflationary f(R) model.We study the effects of dissipation on the dynamics of geodesic matter distribution.This leads the system either to rotation-free or expansion-free but not both simultaneously under geodesic condition.It is found that the system preserves its symmetry in both cases.For the rotation-free case,when there is no dissipation and Ricci scalar is constant,the axial system reduces to FRW universe model.This is exactly the same result obtained in general relativity. | M.Sharif Zunaira Nasir | 2016 | Communications in Theoretical Physics2016，65，4： | 0 |

| 18 | Arabic Sign Language Gesture Classification Using Deer Hunting Optimization with Machine Learning Model显示文摘Sign language includes the motion of the arms and hands to communicate with people with hearing disabilities.Several models have been available in the literature for sign language detection and classification for enhanced outcomes.But the latest advancements in computer vision enable us to perform signs/gesture recognition using deep neural networks.This paper introduces an Arabic Sign Language Gesture Classification using Deer Hunting Optimization with Machine Learning(ASLGC-DHOML)model.The presented ASLGC-DHOML technique mainly concentrates on recognising and classifying sign language gestures.The presented ASLGC-DHOML model primarily pre-processes the input gesture images and generates feature vectors using the densely connected network(DenseNet169)model.For gesture recognition and classification,a multilayer perceptron(MLP)classifier is exploited to recognize and classify the existence of sign language gestures.Lastly,the DHO algorithm is utilized for parameter optimization of the MLP model.The experimental results of the ASLGC-DHOML model are tested and the outcomes are inspected under distinct aspects.The comparison analysis highlighted that the ASLGC-DHOML method has resulted in enhanced gesture classification results than other techniques with maximum accuracy of 92.88%. | Badriyya B.Al-onazi Mohamed K.Nour Hussain Alshahran Mohamed Ahmed Elfaki Mrim M.Alnfiai Radwa Marzouk Mahmoud Othman Mahir M.Sharif Abdelwahed Motwakel | 2023 | Computers, Materials & Continua2023，，5： | 0 |
| 19 | Dark Energy Models and Cosmic Acceleration with Anisotropic Universe in f(T) Gravity显示文摘This paper is devoted to studing the accelerated expansion of the universe in context of f(T) theory of gravity. For this purpose, we construct different f(T) models and investigate their cosmological behavior through equation of state parameter by using holographic, new agegraphic and their power-law entropy corrected dark energy models. We discuss the graphical behavior of this parameter versus redshift for particular values of constant parameters in Bianchi type I universe model. It is shown that the universe lies in different forms of dark energy, namely quintessence,phantom, and quintom corresponding to the chosen scale factors, which depend upon the constant parameters of the models. | M.Sharif Sehrish Azeem | 2014 | Communications in Theoretical Physics2014，61，4： | 0 |
