شہدائے خیر پور ناتھن شاہ
ستون دار پر رکھتے چلو سروں کے چراغ
جہاں تک یہ ظلم کی سیاہ رات چلے
جنرل ضیاء الحق کے مارشل لاء کے خلاف تحریک بحالی جمہوریت 1983ء میں پاکستان پیپلز پارٹی کے پانچ سو ارکان شہید ہو ئے تھے مگر 12ستمبر 1989ء کو سب سے خون ریز واقعہ خیر پور ناتھن شاہ سندھ میں پیش آ یا جب فوج کی گلیوں سے بارہ افراد شہید ہو ئے ۔آج ان کی برسی خیر پور ناتھن شاہ میں منائی جا رہی ہے ۔
The phenomenon of unemployment is one of the problems, which affects the development of individuals and society. Total unemployment or underemployment may be permanent or temporary. Its negative and damaging effects lay an everlasting result especially in times of economic recession. The importance of this study is to explore the role of individual, and methods of solution in the light of Sunnah. Hadith and Sunnah clearly mark the virtues of work and its value and positive impact on the community. Thus we see the greatness of our religion in this concern for human beings and preserving their dignity, and to find ways to ensure decent life, where there is neither no vacuum, nor unemployment.
This study is comprised of five experiments, in the first experiment chemical changes taking place in lipid fraction of pasteurized milk was studied. Raw milk from the same source was at once cooled down to chilling temperature and in second instance it was put on the lab shelf for two hours at ambient temperature and then chilled to same temperature, followed by pasteurization and chilled storage. In the second experiment, samples of UHT milk were tested for chemical characteristics and lipid oxidation. In third experiment, impact of UHT treatment (142oC for 2 sec) and 90 days ambient storage (30-35oC) on protein and amino acid profile of UHT milk and sedimentation was investigated. In fourth experiment, samples of UHT Treated products were stored for 90 days. Transition in antioxidant capacity, vitamin A, E, fatty acid profile was studied. Transition in protein profile, Maillard reaction products and lipid oxidation of flavored UHT treated milk was investigated. In fifth experiment, Samples of mango flavored UHT milk 200 ml pack (475 Nos.) were purchased from the market and stored at ambient temperature for the duration of 90 days. Proteolysis, hydroxyl methyl furfural furosine, Nε-carboxymethyl lysine, FAP, FFA, PV and sensory characteristics were studied at 0, 45 and 90 days of storage. It was observed that chemical characteristics and storage stability of raw milk in the second instance was different from the milk cooled at once. Therefore, it is recommended that milk collection system in the developing countries should be improved to avoid any delay in between milking and chilling of raw milk. The results of the second experiment disclosed that fatty acid and triglyceride profile were not affected till 60 days with a steady increase in lipase activity. Strong correlations between peroxide value and induction period were established. For the anticipation of oxidative stability of UHT milk, induction period can be used. After UHT treatment, β-lactoglobulin, β-lactalbumin, immunoglobulin and serum albumin decreased by 12.1%, 15.4%, 10.6% and 10.2% with no effect on casein fractions. Sedimentation was comprised of 14.9% αs1-casein, 3.42% αs2-casein, 9.88% β-casein, 2.27% κ-casein, 4.36% β-Lactoglobulin, 1.88% β-lactalbumin, 1.84% immunoglobulin and 0.61% Serum Albumin. Out of 80% casein and 20% whey, 38.5% and 8.7% became the part of sedimentation. Tyrosine content of flavored UHT milk increased during the storage. Tyrosine content of flavored UHT milk at 0, 45 and 90 days of storage were 3.5, 6.9 and 15.2 µg tyrosine/ml. HMF content of UHT milk at 0, 45 and 90 days of storage were 1.56, 4.18 and 7.61 (µmol/L). Furosine content of flavored UHT milk at 0, 45 and 90 days of storage intervals were 278, 392 and 561 mg/100g protein.
