This research defines the software life cycle models and refers to the significance of the requirements gathering and analysis. There are many methods for capturing software requirements; this work focuses on one informal, two semiformal and two formal methods. Informal method in the requirements elaboration uses QUARS Tool techniques to deal with natural language. Semiformal methods are Unified Modeling Language (UML) and User Requirements Notation (URN). UML and URN supports different types of diagrams to view the system, URN is different from UML, and it is specially developed for telecommunication services and systems. The conversion of the URN into the other International Telecommunication Union -Telecommunication (ITU-T) languages is also supported. Formal methods use set-theory and logics, Specification and Description Language (SDL) and Knowledge Acquisition in automated specification or?Keep All Objectives Satisfied (KAOS) are examples of formal methods. KAOS uses graphical notations to elaborate the problem. Requirement engineering process has a great importance in the process of software development. Study demonstrates that to produce quality software more attention should be paid in improving the requirement engineering process. In this research five key process areas are described for the improvement of the requirement engineering process. First is the goal-based methodology in requirement engineering process. The second area is to support the cyclical and incremental activities in requirement engineering process. Third area is for encouraging the stakeholders involved in requirement engineering process. Fourth is for the support of management and fifth is for defining the planning phase of requirement engineering process.

اپنی تصویر بھی یوں مجھ سے چھپاتی کیوں ہو

اپنی تصویر بھی یوں مجھ سے چھپاتی کیوں ہو
دوسرا چہرہ بہانے سے دکھاتی کیوں ہو

تم کو معلوم ہے بنجارے کہیں ٹھہرے ہیں؟
جانے والوں کو بھلا ایسے بلاتی کیوں ہو

ایک شاعر کا یہ شکوہ ہے شکایت بھی ہے
جب دکھانی نہیں تصویر بناتی کیوں ہو

تم بھی مشتاقِ محبت ہو سبھی جانتے ہیں
جذبۂ دل کو بتائو تو چھپاتی کیوں ہو

جب ترے بس میں نہیں روگ محبت والا
تم فضاؔ دل کو یہی روگ لگاتی کیوں ہو

A Study of Pakistan’s Various Reform Policies Regarding Islamic Seminaries

ABSTRACT: Pakistan is an Islamic country based on Islamic ideology where society has an emotional attachment with religion, hence an expanded network of Dini Modaris [traditional institutions of Islamic learning] is prevailing in urban as well as in rural areas of the country; where the teaching- learning process remains continue in a traditional way. While on other hand, at the same time, modern education system is followed by government and non-government run institutions. These two different systems with different ideologies and pedagogical techniques have produced two different social classes with different world views about the way Pakistan should be managed. This situation of education system is worrying. In an Islamic welfare state, ideally speaking, serious efforts are required to be done in order to eliminate the gulf between the two systems entirely having antagonistic approaches. In such perspective, this paper is aimed to study the efforts and practical steps, taken for the reforms and development of Dini Modaris by various governments of Pakistan as per their policies.

Preparation and Nutritional Evaluation of Poultry Farm Litter and Dead Birds Compost for Use in Poultry Feed

The poultry industry produces large amount of wastes, including poultry litter, manure, and dead birds, requiring regular and prompt disposal during the course of a normal production cycle. Disposal by burial, incineration, landfills, rendering, on-farm freezers, or other preservation techniques is not adequate and may have serious implications for animal, poultry, and human health. Poultry farmers need a convenient, environmentally acceptable, and bio-secure way of disposing poultry carcasses. A potentially efficient and cost-effective option for the disposal of poultry waste (litter, dead birds) is to recycle the waste as a feedstuff for use in poultry feed, which could be possible through proper composting of the litter and dead birds, and optimized feed management practices. The utilization of dead hens and rendered spent hens as a feed source is well documented in the literature, but, to our knowledge, no literature exists regarding the use of compost in poultry feed. It was hypothesized that including compost in poultry diets at levels up to 10% could produce similar performance gains as diets without compost while being more cost-effective. Thus, this study was planned to explore the effect of including compost in the diet on performance, blood biochemical profile, and immune antibody response of commercial broilers, quail broilers, and commercial layers. The study was executed in two phases. In phase I, litter and dead bird compost was prepared and chemically analyzed. In phase II, three biological trials were conducted to assess the feeding values of compost for commercial broilers (experiment 1), quail broilers (experiment 2), and commercial layers (experiment 3). In experiment 1, a total of 300 day-old broiler chicks (Cobb-500) were randomly distributed to five treatment groups. Each treatment group contained 10 birds and experiments were replicated six times using a completely randomized design (CRD). In experiment 2, a total of 1200 newly hatched quail chicks (Coturnix coturnix japonica) were distributed to five treatment groups. Each treatment group contained 40 birds and experiments were replicated six times using a CRD. In experiment 3, a total of 150 laying hens (Novogen White, 18-week-old) were distributed to five treatment groups. Each treatment group contained six hens and experiments were replicated five times. The experimental diets consisted of increasing levels of compost (0, 2.5, 5, 7.5, and 10%), but were otherwise iso-caloric and iso-nitrogenous. Data were analyzed by one-way ANOVA under CRD. In experiment 1, there were no differences (P>0.05) in feed intake, live weight gain, feed efficiency, and mortality for birds fed compost at any level compared to birds fed the control diet. Carcass yield and relative weights of breast, thigh, wing, liver, gizzard, and heart were not affected (P>0.05) by the compost supplement to the diet; however, the highest level of compost (10%) caused a marked decrease (P=0.028) in abdominal fat content compared to control and 2.5% compost diets. Similarly, there were no differences (P>0.05) in sensory grading, compositional profile, serum biochemical indices, and immune-related parameters in birds fed the different diets. Birds fed the 10% compost diet, however, showed the lowest (P=0.0001) feed cost per kg weight gain compared to those fed the control diet. Similarly, in experiment 2, feed intake, live weight gain, feed efficiency, and mortality for birds given the compost supplemented diet was comparable (P>0.05) to that of birds fed the control diet. Carcass yield and relative weights of breast, thigh, wing, liver, gizzard, heart, and abdominal fat were not significantly different across treatments (P>0.05). Although, a slight reduction in breast and thigh weights was observed in chicks fed compost at 10% level compared to control chicks, but statistically this difference was not significant (P>0.05). Similarly, no differences (P>0.05) in sensory properties, compositional profile, serum biochemical indices, and immune-related parameters were observed among the diets. The experimental group fed compost at 10% showed the lowest (P=0.0001) feed cost per kg weight gain compared to control group. In experiment 3, hen performance parameters, including average daily feed consumption, final body weight, egg production, egg weight, cumulative egg mass, feed efficiency values, livability, and uniformity percentage, were not affected (P>0.05) by the addition of compost to the diet at any level. Although, hens fed the diet containing 10% compost exhibited slightly lower egg production and egg weight compared to control hens, but statistically this difference was not significant (P>0.05). Similarly, there were no differences (P>0.05) in egg quality, yolk fatty acid composition, egg sensory characteristics, serum biochemical profile, and immune-related parameters among the diets. Finally, the lowest (P=0.0001) feed cost per kg egg mass was observed in the hens fed diets containing compost 10% compared to control hens. Taken together, these data indicate that compost can be utilized in diets for commercial broiler, quail broiler, and commercial layer up to 10% without compromising performance, blood biochemical profile, and immune antibody response. Furthermore, the utilization of compost as a feed resource may reduce feed cost per kg live weight gain and feed cost per kg egg mass
