ڈاکٹر سید فرید احمد برکاتی نے یکم جولائی ۲۰۰۷ء کو داعی اجل کو لبیک کہا، انا ﷲ وانا الیہ راجعون۔
ڈاکٹر صاحب کے جد امجد مولانا حکیم برکات احمد صاحب اپنے زمانے کے مشہور فاضل، یگانہ استاد اور علوم عقلیہ و حکمیہ میں سرآمد روزگار تھے، یہ بہار سے آکر ریاست ٹونک میں آباد ہوگئے تھے، ٹونک کے والی نے بڑی قدردانی کی اور اپنا خصوصی معالج مقرر کیا، علوم عقلیہ کی طرح طبابت بھی اس خانوادے کا امتیاز تھا، اس میں کئی نامور طبیب گزرے ہیں، ڈاکٹر فرید احمد کے والد بزرگوار شفاء الملک مولانا سید ظہیر احمد برکاتی بھی ایک حاذق طبیب اور ریاست کے نواب صاحب کے معالج خاص تھے۔
یادش بخیر حکیم محمد سعید بانی ہمدرد دواخانہ کراچی کے دست راست اور راقم کے مخلص کرم فرما جناب مسعود احمد برکاتی صاحب اسی خانوادے کے گوہر ناب ہیں، ڈاکٹر فرید احمد اپنی خاندانی ذہانت، علم و فضل، شرافت، ملنساری اور سخاوت کے حامل تھے، آٹھ برس کی عمر میں قرآن مجید حفظ کیا، دارالعلوم خلیلیہ نظامیہ ٹونک سے ابتدائی اور دینی تعلیم حاصل کی، علی گڑھ مسلم یونیورسٹی سے عربی میں ایم اے کیا اور اول پوزیشن حاصل کی، پھر راجستھان یونیورسٹی سے اردو میں ایم اے اور پی ایچ ڈی کیا اور یہیں تدریسی خدمات انجام دے کر ۲۰۰۲ء میں سبک دوش ہوئے۔
ان کا تحقیقی مقالہ ’’فرہنگ کلیات میر‘‘ ۱۹۸۸ء میں شائع ہوا تھا، اسی زمانے میں پورے ملک میں مولانا ابوالکلام آزاد صدی تقریبات منائی جارہی تھیں، راجستھان یونیورسٹی کے شعبہ اردو فارسی میں بھی مولانا پر سمینار ہوا تھا، اس میں شرکت کے لیے گیا تو ڈاکٹر فرید صاحب سے ملاقات ہوئی اور انہوں نے اپنی کتاب معارف میں تبصرے کے لیے عنایت کی، اس سے ان کی محنت اور لغت میں مہارت...
Malaria is still a health problem in Indonesia. The number of malaria cases according to the 2018 RISKESDAS reached 8076 cases, and the highest number was obtained from Papua province with 3,334 cases. Multiple infection malaria in Indonesia according to RISKESDAS 2018, has a rate of 0.01% of the total cases, namely Plasmodium Falciparum malaria and Plasmodium non Falciparum malaria. A 47 year old man was referred from the clinic with complaints of high fever preceded by chills 10 days before being admitted to the hospital. Accompanied by shortness of breath, unable to get off the treatment bed due to feeling very weak, nauseous, sick and having a bulging stomach. Physical examination revealed a pale conjunctiva, ronkhi in the lower field of the right lung, dim percussion in the basal of the left lung, hepatomegaly, splenomegaly, shifting dullness. Ring form vivax, on chest X-ray found a left pleural effusion. It is known that the patient previously lived in Papua from September 2018 to May 2019. During treatment, the patient was given artesunate injection therapy, dihydroartemisin + piperaquine and primaquin for seven days of treatment. At the end of the treatment, another chest X-ray was performed and re-examination of the peripheral blood smear, no more pleural effusions were found and no parasites were found on re-examination of the peripheral blood smear. Mixed infection of vivax and falciparum malaria, is a rare case that may occur in endemic areas where both plasmodium can be found. The prevalence in Indonesia according to RISKESDAS is only about 0.01% of all malaria cases in Indonesia.
Theoretical Investigations on Enhancement of Nonlinear Optical Properties of Alkali and Alkaline Earth Metal Doped X12Y12 Nanocages Materials with nonlinear optical response find applications in laser physics, optical fibers, optical computing, optical data handling, optical wave guides and gyroscopes, optical limiters, sensors and scanners. A number of strategies have appeared in the literature to design high performance nonlinear optical materials. A few well studied strategies are bond length alternation (BLA), synthesis of octupolar molecules, molecules with diradical character electrides, and alkalides. A relatively less explored strategy is doping of organic and inorganic systems with alkali metals. Doping with alkali metal generates diffuse excess electrons which reduce the transition energies for crucial excitations. The present research aims at exploring the potential of alkali and alkaline earth metal doping on the nonlinear optical response of X12Y12 nanocages. The objective of this study is not only to find the best nano-cage for doping but also to compare alkali metal with alkaline earth metal doping (substitutional and exohedral). Prior to this study, the literature illustrated only exohedral doping of alkali metal on Al12N12 nano-cage. In this study, Al12N12, B12N12, Al12P12 and B12P12 nanocages were studied. The stabilities of exohedral and substitutional doped nanocages are evaluated through adsorption and cohesive energies, respectively. The exohedral complexes of alkali metal are quite stable as reflected from their adsorption energies; however, certain alkaline earth metal doped systems have negligible adsorption energies. Cohesive energies of substitutional doped nanocages were less than the undoped system. Regardless of the doping mode, the HOMO-LUMO gaps are reduced significantly. The H-L gaps are reduced up to 74% of the original value. The maximum change in H-L gap is observed for Ca@PtopAl12P12 where the gap is reduced to 74.4% of the pristine AlP nanocage. The decrease in H-L gap also reduced the energies for crucial excitation which leads to significantly higher hyperpolarizabilities. The hyperpolarizabilities of the doped nanocages generally range from 1.3×102 au to 7.9×105 au which are several orders of magnitude higher than the values for pristine nanocages. Two level model is also applied to rationalize the obtained hyperpolarizabilities of certain doped systems. The trends of xi hyperpolarizabilities from two level method agree with the hyperpolarizability values from DFT calculations. 2nd hyperpolarizability values, which are real measure of practical application of a system are evaluated through βvec, are also remarkably high and in the same order as first hyperpolarizabilities. The participation of diffuse excess electrons in boosting nonlinear optical response of these doped systems is confirmed through analysis of partial densities of states. The results offer new insight into structure property relationship of inorganic fullerenes in designing new high performance nonlinear optical materials.
