for a given riemannian manifold (m,g),it is an interesting question to study the existence of a conformal diffemorphism (also called as a conformal transformation) f : m ! m such that the metric g? = fg has one of the following properties: (i)(m; g?) has constant scalar curvature. (ii)(m; g?) is an einstein manifold.
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
Ageratum houstonianum occurs as a common agricultural weed, it is managed in small and large cropping situation by tillage can contribute to soil fertility waste mulch. The aim of this study was employ the pharmacognostic taxonomic parameters evaluate leaves houstonianum. were collected, identified, air dried, pulverized subjected microscopy, micromeritics, chemomicroscopy, fluorescence, solubl...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
INTRODUCTION Pulsatile Drug delivery systems are gaining a lot of interest as they deliver the drug at the right site of action at the right time and in the right amount, thus providing spatial and temporal delivery and increasing patient compliance. Pulsatile Drug Delivery systems are basically time-controlled drug delivery systems in which the system controls the lag time independent of envir...
The aim of this study was to evaluate microencapsulated controlled release preparations of tolmetin sodium using ethylcellulose as a retardant material. Microspheres were prepared by using water-in-oil-in-oil (W/O(1)/O(2)) double-emulsion solvent diffusion method, using different ratios of ethylcellulose to tolmetin sodium. Span 80 was used as the droplet stabilizer and n-hexane was added to ha...
Orthorhombic paracetamol (form II) can be obtained from ethanolic solution when seeding technique is applied although it converts to monoclinic (form I) upon contact with the solvent. In the present work different cooling temperature T(C) (-20, -10 and 0 degrees C) was applied under fixed agitation (700 rpm) and the crystalline product was harvested after different crystallization time t(H) (20...
*Research Scholar Department of Pharmacy, School of Medical and Allied Sciences Galgotias University, Gautam Buddh Nagar, Greater Noida (U.P.) e-mail: [email protected] Abstract: The objective of the present study was to develop floating microspheres of Gliclazide in order to achieve an extended retention in the upper gastrointestinal tract, which may result in enhanced absorption a...
