作者： F. Akbar N. sultana University of Sargodha Pakistan

The main purpose of this paper is to prove some common fixed point theorems for pointwise R-subweakly commuting maps on non-starshaped domains in p-normed spaces and locally convex topological vector spaces. As applications, invariant approximation results are established. This work provides extension as well as substantial improvement of several results in the existing literature.

Hepatic Histoplasmosis: An Update

Journal of Clinical and Translational Hepatology 2022年第4期10卷 726-729页

Histoplasma capsulatum is the most common cause of en-demic mycosis in developing countries. It is a self-limited and asymptomatic disease in immunocompetent individu-als but remains a frequent cause of opportunistic infection in patients with compromised immune status. Liver in-volvement as a part of disseminated histoplasmosis is well known. However, liver infection as a primary manifestation of histoplasmosis without evidence of primary lung involve-ment is rare. In conclusion, clinicians should be aware of isolated histoplasmosis affecting the hepatobiliary system, and careful evaluation is warranted to confirm the diagno-sis. Given the appropriate clinical context, histoplasmosis should be considered in both immunocompetent and immu-nocompromised patients, regardless of pulmonary symp-toms, in non endemic as well as endemic areas.

Synthesis, Crystal Structure and Antimicrobial Activity of {[Bis(pyridine-κN)bis(3,5-dinitrosalicylato κ-O,O')Zn(Ⅱ)][bis(pyridine-κN)Zn(Ⅱ)]}

引用

Chinese Journal of Structural Chemistry 2016年第5期35卷 705-712页

作者： CHANG Fouzia MEMON najma AHMED Muhammad Naeem TAHIR Muhammad Nawaz MEMON Shahabuddin CHANG Abdul Sattar BHANGER Muhammad Iqbal CHANDIO Anwer National Centre of Excellence in Analytical Chemistry University of Sindh Department of Chemistry The University of Azad Jammu and Kashmir Department of Physics University of Sargodha HEJ Research Institute of Chemistry ICCBS University of Karachi

A novel {[bis（pyridine-κN）bis（3,5-dinitrosalicylato κ-O,O＇）Zn（Ⅱ）][bis（pyridine-κN）Zn（Ⅱ）]}（C_（34）H_（24）N_8O_（14）Zn_2） was synthesized by a self-assemble method at room temperature. The molecular structure was determined by single-crystal X-ray analysis. The compound crystallizes in the monoclinic system, space group P2_1/n with a = 12.2156, b = 13.5696, c = 22.5602 A, β = 90.061o, Z = 4 and V = 3739.6（3）A^3. The new 1D binuclear coordination polymer {[bis（py-κN）bis（3,5-dinitrosal κ-O,O′） Zn（Ⅱ）][bis（py-κN）Zn（Ⅱ）]} resulted from two different types of moieties. The polymer [bis（py-κN）bis（3,5-dinitrosal κ-O,O′）Zn（Ⅱ）] unit is connected with [bis（py-κN） Zn（Ⅱ）] by zigzag topology. One zinc（Ⅱ） cation has a six-fold coordination environment, in which the metal atom is connected with four oxygen atoms of two 3,5-dinitrosalicylic acids to form equatorial bonds and two nitrogen atoms of pyridine to generate the axial bonds. Other four-fold nucleus contain two Zn-O bonds from different 3,5-dinitrosalicylic acids and two bonds with the Natom of pyridine. Antimicrobial assay results indicated that the compound showed moderate activities against different bacterial and fungal strains.

Vibration characteristics of FGM circular cylindrical shells filled with fluid using wave propagation approach

引用

Applied Mathematics and Mechanics(English Edition) 2009年第11期30卷 1393-1404页

作者： Zafar Iqbal Muhammad Nawaz Naeem Nazra sultana Shahid Hussain Arshad Abdul Ghafar Shah Department of Mathematics University of Sargodha Department of Mathematics G. C. University Faisalabad Department of Mathematics University of Sargodha Department of Mathematics The Islamia University of Bahawalpur

The vibration characteristics of a functionally graded material circular cylindrical shell filled with fluid are examined with a wave propagation approach. The shell is filled with an incompressible non-viscous fluid. Axial modal dependence is approximated by exponential functions. A theoretical study of shell vibration frequencies is analyzed for simply supported-simply supported, clamped-simply supported, and clamped-clamped boundary conditions with the fluid effect. The validity and the accuracy of the present method are confirmed by comparing the present results with those available in the literature. Good agreement is observed between the two sets of results.
