طاقت کا سرچشمہ

طاقت کا سرچشمہ

طاقت کا سر چشمہ عوام ہوتے ہیں ۔جس دن انہیں اپنی طاقت کا احساس ہو گیا تو ایسا انقلاب برپا ہو گا ۔اس دن وڈیرے جاگیردار سرمایہ دار پیسے کے بل بوتے پر سیاست کر نے والے اسٹیبلشمنٹ اور اس کے گماشتے نا م نہاد عوام کی لاتوں سے ایسے اچھالے جائیں گے ۔

جب تخت گرائے جائیں گے جب تاج اچھالے جائیں گے

اب ٹوٹ گریں گی زنجیریں اور زندانوں کی خیر نہیں

اسلامی تعلیمات كی روشنی میں پسند كے نكاح كا تحقیقی جائزہ

lam is a Moderate ShariahAll its orders are free from exaggeration. Islam gives relaxation in the man's natural instincts and desires and checks to cross such limits which are based on the Principles of Prohibition. That is why, the one hand[ man is stopped strictly to do any wrong act while on the other side it was necessary to provide the others suitable and fair ways for catharsis. Moreover, it is the requirement of the man's mental and Shariah need. That there should be a legitimate contact between man's and woman's relationship-it is called"Nikah" in the light of the Holy Qura ’n and the Hadis.In terms of Nikah it must complete authority to men and women for their likings and disliking and the guardians are strictly forbidden to use enforcement and an the other side motivate both male and female that they should take their guardians in confidence while taking any step in this context

Catalytic and Biological Screening of Newly Synthesized Organotin Iv Carboxylates

Di- and tri-organotin(IV) carboxylates (1-47) of the type R2SnL2 [R = CH3, n-C4H9, n-C8H17] and R3SnL [R = CH3, n-C4H9, C6H5, where L= 3-(4-fluorophenyl)-2-methylacrylic acid (HL1), 2-(4-ethylbenzylidene) butanoic acid (HL2), 2-(4-ethoxybenzylidene) butanoic acid (HL3), 3-(4- cyanophenyl)-2-methylacrylic acid (HL4), 3-(4-ethoxyphenyl)-2-methylacrylic acid (HL5), 3-(2- fluorophenyl) 2-methylacrylic acid (HL6), 3-(4-fluorophenyl) acrylic acid (HL7), 3-(4- cyanophenyl) acrylic acid (HL8) have been synthesized and characterized by various analytical techniques such as elemental analysis, FT-IR, NMR (1H, 13C) and single crystal X-ray analysis. The results showed that the ligands coordinate with Sn atom via carboxylate moiety (COO−) with bidentate mode of binding. The diorganotin(IV) dicarboxylates exhibited distorted octahedral or skew trapezoidal geometry in solid state while the coordination number around tin changed from six to five in solution state. The triorganotin(IV) carboxylates exhibited polymeric trigonal bipyramidal geometry in solid state while monomeric tetrahedral geometry in solution state. The catalytic activity of the synthesized complexes was assessed in the production of biodiesel. Biodiesel is the monoalkyl ester of long chain fatty acids derived from the renewable feed stock, such as vegetable oil and is produced by a transesterification of vegetable oil with methanol. The results revealed that triorganotin(IV) complexes exhibited comparatively higher catalytic activity than their diorganotin(IV) analogues. The synthesized complexes were also screened for their biological activities such as antibacterial, antifungal and cytotoxicity. The results showed that triorganotin(IV) complexes exhibited more bactericidal, fungicidal and cytotoxic effects than diorganotin(IV) complexes. DNA interactions studies of the ligands and synthesized complexes were investigated by UV-Vis absorption spectroscopy. The results showed that both ligands and complexes interact with DNA via intercalation as well as minor groove binding.
