Pectinase recognized as an industrial important enzymes which occupies 10 percent in enzyme production of world while 25 percent of food production. While keeping in view in the light of above scenario the study was design to produce pectinase from local agro wastes. The Pomelo (Citrus Grandis) was considered as novel substrate for pectinase production through solid state fermentation by Aspergillus niger. In first portion of this study, the OFAT (one factor at a time) was opted for optimizing the conditions of temperature, pH and time period for pectinase production. While the other factor was optimized thorugh RSM-DOE (Respone Surface Methadology), a statistical tool for the analysis of variant factor on pectinase activity. About 14 RSM trial were conducted by employing following condition i.e. Substrate (3-28g), inoculum level (1.5-7.5ml) nitrogen (0.625-1.375g), moisture (5-105%). The highest activity of pectinase was observed at pH (5), temperature (30 ?C), incubation day (4 ) by OFAT. In RSM maximum activity at 279.2 U/mL were achieved at optimize temperature 30 ?C, pH 5, day 4 th , moisture level 30%, inoculum size 6ml, substrate 3g and nitrogen level at 0.250g. For purification, ammonium sulphate, dialysis and gel chramatograpghy was performed. The results indicates that at 60% ammounium sulphate precipitation was achieved with specific enzyme activity at 0.856U/mg recorded after purification. Present finding proved that Pomelo peel was abundant and cheap source for production at commercial.

دکھیارے

                ’’دکھیارے‘‘از انیس اشفاق لکھنؤ کی زوال پذیر تہذیب کی عکاسی کرتا ہوا یہ ناول جس میں انیس اشفاق نے بہت سادہ اسلوب زبان اختیار کیا ہے۔ مصنف بہت خوبصورتی سے حال اور ماضی کے واقعات کو بیان کر رہا ہے اور ان واقعات کو حقیقت کے اس قدر قریب تر بتایا ہے کہ کہیں بھی کوئی جھول نظر نہیں آتا۔ مصنف نے ذکر کیا ہے کہ غربت اس قدر بڑھ گئی ہے کہ مکان کی قرقی ہو گئی ہے۔کرداروں میں ایک ماں اور اس کے تین بیٹے ہیں۔ ایک بیٹا ذہنی عارضے میں مبتلا ہے جس کو جنونی کیفیت ہونے پہ یہ احساس ہی نہیں ہوتا کہ وہ ماں کو اپنی وحشت کا نشانہ بنا رہا ہے۔

                مصنف نے ناول میں حالات و واقعات کو اس طرح بیان کیا ہے کہ تمام کڑیاں ایک دوسرے سے باہم مربوط ایسے معلوم ہوتی ہیں کہ بات میں سے بات نکلتی ہوئی محسوس ہوتی ہے۔ ناول کے آغاز میں ہی مصنف حال میں بات کرتے کرتے اچانک بات کا رخ کچھ اس طرح سے موڑ دیتے ہیں کہ بات ماضی میں چلی جاتی ہے۔ ایسا لگتا ہے کہ مصنف نے خودان سب حالات و واقعات کو قریب سے محسوس کیا  اور پھر قلم کے ذریعے اس کو ہم تک پہنچایا۔

                ’’ماں ‘‘ نے خود جس طرح حالات کا سامنا کیا  اور اولاد کو بتایا نہیں کہ یہ مکان جس میں وہ رہتے ہیں ان کا نہیں ہے تو پہلی بار پتا چلنے پر احساس ہوا کہ اس بات کو چھپا کر خود تک رکھنا ماں کے لیے کتنا تکلیف دہ تھا۔مکان کی قرقی ہونے پر راز افشاں ہوا کہ باپ نے یہ مکان گروی رکھا ہوا تھا۔ماں نے جیسے تیسے مقدمہ لڑنے کی کوشش...

The Socio-Economic Implications of Decline in Artisanal Fishing and its Effect on Women: A Case Study of Shams Pir Island, Karachi

Artisanal fishing is carried out in the coastal villages of Karachi. Through centuries, these fishing villages have maintained their traditional practices of fishing. Shams Pir Island is in vicinity of Karachi coast. The main occupation of islanders is artisanal fishing which is extremely threatened by various factors. Historically, in coastal communities of Karachi, women were part of fishing and its related activities. With the decline in traditional fishing methods, females have been withdrawn from fishing work. Implications of this process have been drastic for fishing households such as increased poverty, unemployment, environmental degradation etc. The research is conducted to highlight these problems especially from gender perspective. It is exclusively based on females of Shams Pir Island. Female’s socio-economic conditions, family status, perceptions on different contemporary issues pertaining to the endangered livelihood of their family and its relation with environmental changes is investigated in particular. In total, sixty women representing fishing households, few community leaders and representatives of fisher folk’s NGO were interviewed. The results emphasized the livelihood issues of females and their perceptions on environment and climate change. The vulnerabilities of females in fishing communities have been discussed in detail. ______

Development of Productitive Enhancement Framework for Private Sector Autom Otive Manufacturing Industry of Pakistan

Organizational productivity is one of the basic tools to gauge its competitiveness. Research has proven that methodologies for gauging productivity are lacking in industries globally, and mostly non-standard tools are used to measure and evaluate productivity. In Pakistan specifically, not enough efforts have been put in place to gauge and enhance the productivity of manufacturing industry. This research is focused on identifying the prevalent status of productivity in automotive industry of Pakistan and then suggesting a productivity enhancement framework. This mixed methodology research has been conducted using both qualitative and quantitative methods. Sequential explanatory design in combination with sequential exploratory design was used as suggested by Creswell [106]. Quantitative research was conducted by carrying out productivity analysis of the industry using secondary data from sample companies. Authentic government sources, such as Engineering Development Board and two national level associations i.e. Pakistan Automotive Manufacturers Association (PAMA) and Pakistan Association of Automotive Parts and Accessories Manufacturers of Pakistan (PAAPAM) were consulted for data collection. Secondary data for ten years covering FY 2000-2010 for two major automotive manufacturing firms was gathered. Total Productivity and all partial productivities were computed using methodology proposed by Sumanth [4], while Total Factor Productivity (TFP) was computed using Cobb-Douglas production function. Results gathered showed low productivity status of the industry as compared to that of international industry. In order to develop a productivity enhancement framework, qualitative research was conducted by collecting primary data through qualitative interviews from top management of 26 automotive manufacturing companies. A total of 40 interviews were conducted on the basis of theoretical saturation and theoretical sampling. Open ended questions used for survey were compiled from the internationally published literature for validity and reliability requirements. Using explanatory and descriptive study, role of technology in productivity enhancement of the industry was examined. Findings of this research have been used to develop a productivity enhancement framework for the industry. Developed framework was compared with the framework of 6 different countries, including USA, UK, Sweden, India, China and Thailand [33], [36], [37], [44], [45]. Comparison resulted in emergence of the finalized productivity enhancement framework of the industry. This framework was then implemented in one of the major auto parts manufacturing companies of Pakistan for its validation. Results of the implementation not only validated the model but also depicted that there is an immediate need to implement these concepts for productivity enhancement. The cost- effective solutions suggested in this model and its cross cultural comparisons also show that this model can be used for manufacturing industries in general in the developing countries.
