The demand of biscuits is increasing day by day, due to change in life style of people and convenient foods with improved formulations are making their way to market shelves. Proximate composition of different materials such as dates, peanuts and vetch protein isolate are found suitable for the preparation of DFBB. Sucrose, the main sweetener for biscuits bars could be replaced with fruit sugars that are more digestible and sweet with fewer calories. Low grade dates were used to prepare date-fructose (DF) by using enzyme assays. DFBB with 15% sucrose replacement with date fructose was found the best in terms of physical and sensory characteristics. For improving the protein quality of date-fructose biscuit bars, protein isolates from cheaper and locally available Indian vetch (Lathyrus sativus) were incorporated (IVPI).Sensory parameters especially color, taste, flavor and overall acceptability were affected with the replacement of IVPI and DF in DBB at different levels. 15% IVPI 15% DF replacement into DFBB did not affect the physical and sensory qualities. For 90 days shelf life study, levels of natural antioxidant extracts obtained from peanut peel and withania coagulans were optimized by using Response Surface Methodology (RSM). Optimized levels; 0.21% peanut peel and 0.32% withania coagulans extracts were found to provide the highest response in DFBB without affecting sensory characteristics during storage. Calorific value, free fatty acids and peroxide value,minerals content were non-significantly affected, while amino acids profile was greatly improved in DFBB. Biochemical serum profile and protein quality of the DFBB were evaluated through Spargue-Dawley rats studies. Biological value of BFBB was improved as a result of added IVPI. Serum electrolytes were affected non-significantly among groups. Lipid profile wasaffected significantly within diet groups, while study seasons remained non-significant. ALP, Bi.T, ALT, AST and blood glucose were significantly found lower as compared to control.No effect was observed on the in-vitro protein (IVPD) and starch digestibilities (IVSD). All the bars were acceptable with good sensory characteristics but bars containing medium level (0.5% of optimized combined levels of extracts) of antioxidant extracts were maximally preferred. DFBB achieved 3.53±0.4Kcal/gcalorific value. It was concluded that DFBB containing 15% Indian vetch protein isolate, 15% date fructose and 0.5% peanut peel and withania coagulans blended extracts were proved as the best biscuit bars having good sensory qualities and have 90 days shelf stability.

حافظ ہدایت حسین

حافظ ہدایت حسین ؍ علامہ راشد الخیری ؍ مولانا شیر علی
میری علالت کے زمانہ میں ملک و ملت کی کئی نامور ہستیوں نے اس دنیائے فانی کو الوداع کہا حافظ ہدایت حسین صاحب مرحوم اس صوبہ کے مسلمانوں کی بڑی دولت تھے، اس دولت کا چھن جانا ہماری سب سے بڑی محرومی ہے، دلی کے پایہ تخت کی بھی ایک یادگار مٹ گئی، یہ مولانا راشد الخیری کی ذات تھی، جس نے اپنی ساری عمر مسلمان عورتوں کی علمی و ادبی و تعلیمی خدمت گزاری میں بسر کردی، دکن کے خزانہ کا بھی ایک قیمتی ہیرا گم ہوگیا، یعنی مولانا شیر علی صاحب سابق مدرس اعلیٰ دارالعلوم ندوہ و سابق استاد کلام جامعہ عثمانیہ نے وفات پائی، مرنے والے مرگئے، مگر ان کے کارنامے دنیا میں یادگار رہ گئے۔

Analyse psychosociale de la littérature féminine en Mauritanie

Over the years, Mauritanian Moorish women have managed to have their own poetry, an oral literature known locally as "tebrāʕ" translated into French by the word "ingenuity", sometimes also "invention". It is a love poetry originally used by girls or by women in general to express feelings that social norms prevent them from manifesting publicly. Tebrāʕ is deeper than a mere female expression of passion, it is rather a social and psychological state of mind that empowers women and helps them break taboos virtually for a short period of time. This article is an analytical reading of Tebrāʕ and presents new models and ways of examining this oral literature. It tries also to answer several questions which can be summarized as follows: Can this form of poetry be considered as a female literature? The closed circle where these words are composed and pronounced, can it be considered a therapy session? And above all, what power do these women and girls derive from this practice? This article is also a study of the perception of men and women in Mauritania in relation to this oral art practice based

Wavelets and Radial Basis Functions in Scienti C Computing

The present work is an application of wavelets and radial basis functions to numerical computing. More specifically, we have used Haar and Legendre wavelet for applications of wavelets and multiquadric for applications of radial basis functions. The application areas considered in this thesis are the numerical solution of Integral Equations (IEs), various order Integrodifferential Equations (IDEs), systems of IEs, Elliptic Partial Differential Equations (EPDEs), Parabolic Partial Differential Equations (PPDEs) and highly oscillatory integrals. A few theoretical results are proved for efficient evaluation of some particular systems that arise when we apply one- or two-dimensional Haar wavelet in the wavelet collocation method. Based on these theoretical results new numerical methods based on Haar wavelet are developed for solution of IEs, IDEs and systems of IEs. EPDEs are solved numerically using collocation methods with Haar and Legendre wavelet. Legendre wavelet is also applied for the numerical solution of PPDEs. A new method based on multiquadric radial basis functions is introduced for numerical solution of highly oscillatory integrals. While applying Haar wavelet to numerical solution of IEs we have considered both nonlinear Fredholm and nonlinear Volterra IEs of the second kind. Similarly in case of IDEs a Haar wavelet based method is applied to find numerical solution of first and higher orders nonlinear Fredholm and nonlinear Volterra IDEs. The main advantage of this method is that it is generic as it can be applied to IEs, IDEs and systems of IEs. More specifically the new approach aims at the numerical solution of Fredholm, Volterra and Volterra-Fredholm types of IEs, IDEs and IDEs of higher orders including initial- as well as boundary-value problems. With a slight modification the method can also be applied to find numerical solution of two-dimensional IEs, system of IDEs and partial IDEs. Another distinguishing feature of themethod is that unlike many other existing methods in the literature it does not use any intermediate technique for numerical integration of the kernel function in IEs or IDEs. We have developed two new types of collocation methods based on Haar wavelet and Legendre wavelet for numerical solution of EPDEs. A modification of the collocation method based on Haar wavelet for elliptic differential equations is also introduced that improves the efficiency of the method. The collocation method based on Legendre wavelet is extended to find numerical solution of PPDEs. An advantage of the proposed methods is that it can be applied to different types of boundary conditions (BCs) with slight modifications. For highly oscillatory multidimensional integrals a new Levin’s type method based on multiquadric radial basis functions is developed. Levin method converts the numerical integration problem of highly oscillatory multidimensional integral to a PDE which is subsequently solved using meshless method. The proposed methods are validated on a variety of problems as well as numerical results of the proposed methods are compared with several existing methods from the literature. The numerical results show better performance of the proposed methods for several benchmark problems.
