Two simple and sensitive extractive spectrophotometric methods (Method A and Method B) have been developed for the determination of Escitalopram in bulk and pharmaceutical preparation which are based on the formation of coloured complex of the drug with dyes namely bromothymol blue (BTB) and methyl orange (MO). The ion pair complexes formed was quantitatively extracted into chloroform under the experimental conditions. All the variables have been optimized and the concentration measurements are reproducible with a relative standard deviation of 1.98 and the recoveries are 99-100.7%.

Present study aims to provide a thorough analysis of the various factors that are likely to affect tourism. The general perception is that terrorism is directly linked to the tourism industry and a rise in terrorism the security threat in Pakistan has resulted in the decline of the tourism industry. Therefore, it is necessary for the government to deal with the problem. The study analyzes the various factors effecting tourism and takes terrorism into focus. The concept is new and it surfaced initially during the 1970s. Through various research tools and techniques, we shall try to find the reasons behind the current state of affairs regarding the travel and tourism industry in Pakistan. The research aims to critically analyze the factors affecting the situation and to suggest a concrete solution to the problem through thorough analysis. The sample of the research consists of over 70 respondents that include the respondents from Pakistan as well as those from foreign countries. The research aims to provide a domestic as well as an international perspective on the state of tourism in Pakistan.

The independent dominating set problem is a classical optimization problem and has been shown to be NP-Complete. This study finds a molecular computing model to solve the independent dominating set problem, based on Adleman-Lipton model. It proves how to apply stickers in the sticker based model to construct the DNA solution space of the independent dominating set problem and how to apply DNA operations in the Adleman-Lipton model to solve that problem from the solution space of stickers. The time complexity of the proposed computational model is O(n + 2m) and to verify this model, a small independent dominating set problem was solved. This proves the capacity of molecular computing for solving the complex independent dominating set problem.

This paper explores the level of coordination and cooperation between the academics and industrialists. The data were collected by using in-depth interviews, focus group discussions with different stakeholders of the Management Faculty. This study reveals a lack of coordination and cooperation among the major stakeholders. A lack of trust between the stakeholders, little commitment or heavy workloads among the academics, limited forum for dialogue and unawareness of mutual expectations of each other lead to weak coordination and cooperation between or among them. This low level of coordination and cooperation among the key stakeholders has resulted in low employ-ability among graduates in Universities.

The amino acid composition of proteins from leaves of Acalypha wilkesiana and Tridax procumbens was studied using gas chromatography. A. wilkesiana leaf protein had lower total essential, but higher total sulphur containing and aromatic amino acid content than T. procumbens leaf protein. Both proteins had high contents of essential amino acids, histidine, threonine and valine, though deficient in isoleucine. Thus both proteins may serves as good sources for the supplementation of histidine, threonine and valine

This research will explore conceptual framework of Globalization and subsequently discuss how Globalization affected contemporary work organization in general and Indian work organization located in special economic zones (sezs) in particular.This research is an exploratory qualitative study. It is based on extensive review of literature summing up the findings on the topic in question. Finally an answer to the issues discussed in the systematic literature review has been suggested at the conclusion.

Abstract The development of nanotechnology is making the interest of researchers towards the synthesis of nanoparticles for the bioapplication. Metal oxides such as ZnO have received increasing attention as antibacterial materials in recent years because of their stability under harsh processing conditions, and also because they are generally regarded as safe materials for human beings and animals. Zinc activates 300 enzymes, and it plays a role in many another phenomenons like growth, membrane stability, bone mineralization, tissue growth, and repair, wound healing and cell signaling. Many studies have shown that ZnO nanoparticles have enhanced antibacterial activity. Use of plant and plant materials for the synthesis of Zinc nanoparticles is relatively new and exciting research field. Various plants were used for the synthesis of nanoparticles using green synthesis method

Present study was designed to explore the habits profile of university students. Six habits were selected as effective for the students at university such as, Balance, Time management, Optimism, Team work, Understanding and Organization. A random sample of 148 students was collected from various universities of Islamabad among them 66 were males and 82 were females, their age ranged from 20 to 28 years and their family income level ranged from 25000 to 100000. The findings of the study revealed that the most common habits exhibited by the university students are Balance, Organization and Optimism. University students need to learn how to practice habits of Understanding, Teamwork and Time Management. No gender difference was found in practicing the habit of Balance, Time management and optimism, however male university students score higher on Understanding and Organization as compared to female students. Younger students are more Balance and Organized as compared to the older students, on the other hand older students have the habit of Optimism and understanding as compared to younger ones.

This study aimed to determine the haematological values as well as the phenotypic correlation among the parameters of haematology. One hundred and twenty (120) Japanese quails were raised on a deep litter system. Two experimental diets (starter diet and layers diet) were given to the birds. Blood samples were taken from the birds at six (6) weeks for haematological analysis. According to the result obtained, sex did not have any significant (P> 0.05) effect on any of the haematological parameter. Meanwhile, it was also observed that increment in body weight was found supportive of the haematological parameters.

Neural Networks are being used for character recognition from last many years. This paper presents creating the Character Recognition System, in which Creating a Character Matrix and a corresponding Suitable Network Structure is key. The Feed Forward Algorithm gives insight into the enter workings of a neural network; followed by the Back Propagation Algorithm which compromises Training, Calculating Error, and Modifying Weights. We have made an attempt to recognize handwritten English characters by using a multilayer perceptron with one hidden layer. In addition, an analysis has been carried out to determine the number of hidden nodes to achieve high performance of back propagation network in the recognition of handwritten English characters. The results showed that the MLP networks trained by the error back propagation algorithm are superior in recognition accuracy and memory usage. The result indicates that the back propagation network provides good recognition accuracy of more than 70% of Handwritten English characters.
