در این پروژه نانو کامپوزیت های na y/ hpw ، hpw / nay / aam ، hpw /nay/mcm -41 و hpw /nay/mcm -41 aam تهیه شدند و توسط روش های xrd, ft-ir و tga, sem مورد بررسی قرار گرفتند. نتایج بدست آمده نشان داد مقادیر قابل توجهی از hpw درون کامپوزیت ها ، حتی پس از شستشو باقی مانده است و این نشان دهنده آن است که هتروپلی اسید hpwبشدت به درون منافذ و سطوح کامپوزیت ها متصل شده است. برای تعیین فعالیت کاتالیست ها...
OBJECTIVE Type 2 diabetes adversely affects the liver and kidney function tests. This study was conducted to determine that either the liver and kidney functions are disturbed in the patients having gestational diabetes mellitus (GDM). METHODS One hundred and three women with GDM, and 97 healthy pregnant women (HPW) in their third trimester were registered in the Obs/Gyn Unit of Khyber Teachi...
The aim of this study was to evaluate the therapeutic potential of oxidative stress (OS) reduction by using pyridoindole (PI) antioxidants in adjuvant arthritis (AA). The substances tested were stobadine dipalmitate (STB) and SMe1. AA was used as animal model. The experiments included healthy animals, control arthritic animals and arthritic animals with administration of PI in the oral daily do...
OBJECTIVE The objective of the study was to report the socio demographic risk factors of gestational diabetes mellitus (GDM). METHODS This study was conducted in the Institute of Chemical Sciences, University of Peshawar. In this study 103 GDM and 97 healthy pregnant women (HPW) were registered in Khyber Teaching Hospital (KTH), Peshawar, Pakistan. Women with gestational diabetes were diagnos...
We propose an ultracompact broadband polarization beam splitter (PBS) based on a combined hybrid plasmonic waveguide (HPW). The proposed PBS separates transverse-electric (TE) and transverse-magnetic (TM) modes using a bent lower HPW with vertical nanoscale gaps and a straight upper HPW with a horizontal nanoscale gap, respectively, without relying on an additional coupling region. This design ...
The main objective of this work was to design an innovative method prepare heterogeneous heteropolyacid catalysts. H3PW12O40 (HPW) modified with tin(II) by two methodologies: a conventional aqueous ion-exchange (CS) and redox solid-state (SS). In both cases, Fourier transform infrared spectroscopy (FTIR) X-ray diffraction (XRD) measurements evidenced that Keggin structure preserved. All materia...

Serum uric acid (SUA) and ascorbic acid levels were evaluated in 40 patients preclampsia [18-diabetic pre-eclamptic women (DM-PRW) & 22 without diabetes (PRW)]; 20 normotensive pregnant women [8 with gestational diabetes (G-DM) & rest 12 were healthy pregnant women (HPW)]; and control group consisting of 20 healthy non-pregnant women. SUA values were significantly increased in PRW & DM-PRW as c...
