شاہ ولی اللہ رحمہ اللہ کا نظریہ تشکیل اخلاقیات

This research article consist unique study regarding constitution of Human being character building in the thoughts of eminent philosopher Shah Wali Ullah (1703-1764). In present critique the focus has been made to explore how individual characters build in the specific environments? How surrounding effects on the character building? Moreover linkage of Islamic ‘IB└DA and its positive impact on the Muslim society has been explored. In interpretation of Shah Wali Ullah, All ‘IB└DA are like tools which lead to generate four basic ethics i.e purity and transparency capitulation, gainful and abstinence. These are the basic moral code which are the ultimate result of the four kind of ‘IB└DA i.e prayer, fasting, zakat and hajj. Muslim has inestimable inner power in the form of six lat┐’ef )اطلفئ, )which ultimately resulted upon the change of behavior. Character building are etiquettes, noble practices, decentness and good morality. It is generally refers to a code of conduct, that an individual group or society hold as authoritative in distinguishing right from wrong. Ethics are phenomenon values and can develop up to reasonable universal standards. Conduct in Islam governs all aspects of life and specifically addresses such principles as truthfulness, honesty, trust, sincerity, brotherhood and justice, while Islam forbid false, conspiracy, dodge, rude, irascibility, corruption. To materialize the virtues and disgrace the fake a role model prophet Muhammad (S.A.W) were deputed from Allah to guide the human being. So In present article character building in the theory of Shah Wali Ullah especially while in other Muslims scholars in general has diagnosed.

Preparation of High Specific Activity Radionuclides for Therapeutic Radiopharmaceuticals

Production of radioactive scandium by irradiating natural titanium metal in Pakistan Research Reactor-1 was evaluated. The production rate of scandium-47 ( 47 Sc) and other radioactive scandium was estimated. High specific activity 47 Sc can be produced by irradiating enriched titanium-47 in sufficient quantities needed for therapeutic applications. A new separation technique based on column chromatography was developed. Neutron irradiated titanium was dissolved in hydrofluoric acid, which was evaporated and taken in distilled water. The resulting solution was loaded on silica gel column. The radioactive scandium comes out first and the inactive titanium is removed with 2 M HCl. More than 95% radioactive scandium was recovered, while chemical impurity of titanium determined by optical emission spectroscopy was less than 0.01 μg / mL in final product of 47 Sc. Production of Copper-64 ( 64 Cu) by irradiating copper and zinc metals in a reactor was evaluated. Low specific activity 64 Cu can be easily produced using thermal neutrons via 63 Cu (n, γ) 64 Cu reaction, while use of fast neutrons are mandatory for high specific activity 64 Cu via 64 Zn (n, p) 64 Cu reaction. Natural copper and zinc targets were irradiated in Pakistan Research Reactor-1. Radionuclidic impurities produced by thermal and fast neutrons were determined. Commonly available organic anion exchange resin (AG 1-X8) was used for the separation of no-carrier-added radiocopper from neutron irradiated zinc. More than 95 % 64,67 Cu was recovered. The radionuclidic and chemical purity of 64 Cu was determined. The specific activity of 64 Cu produced by 63 Cu (n, γ) and 64 Zn (n, p) was compared.The metallic cation, 68 Ga (III) is suitable for complexation with chelators either naked or conjugated with biological macromolecules, however, such labeling procedure requires high chemical purity and concentrated solutions of 68 Ga (III), which cannot be sufficiently fulfilled by the presently available 68 Ge/ 68 Ga generator eluate. A method to increase the concentration and purity of generator has been developed. The 68 Ga obtained from a commercial 68 Ge/ 68 Ga 68 Ga eluate (1M HCl) is extracted in methyl ethyl ketone, which is evaporated and taken in a small volume of buffer. Arsenic-77 (T 1/2 = 1.6 d) was produced by irradiating natural germanium in Pakistan Research Reactor-1. The nuclear reaction 76 Ge (n, γ) produces 77 Ge, which decays by emission of β - particles into 77 As. The neutron irradiated target was dissolved in aqua regia, excess of acid was removed by evaporation and finally the solution in basic media was passed through hydrous zirconium oxide (HZO) column. The Ge was quantitatively retained on HZO, while 77 As was present in the effluent. More than 90 % 77 As was recovered. The chemical impurity of Ge in 77 As was <0.01μg/mL. Large columns containing aluminum oxide (Al 2 O 3 ) or gel (e.g. zirconium molybdate) are needed to prepare 98 Mo(n,γ) 99 Mo→ 99m Tc column chromatographic generators that results in large elution volumes containing relatively high 99 Mo impurity and low concentrations of 99m Tc. Post elution concentration of 99m Tc using in house prepared lead cation exchange and alumina column was developed. The principle of the method developed is trapping of anionic pertechnetate on tiny alumina column. This can be only achieved in the absence of sulfate ions. These sulfate ions are removed from the eluate by reaction with lead ions loaded onto a cation exchange column, to precipitate lead sulfate, which is filtered out by the column packing. Using these columns high bolusvolumes (10-60 ml 0.02 M sodium sulfate) of 99m Tc can conveniently be concentrated in 1 mL of physiological saline. This approach also works very effectively to prepare high specific volume solutions of 99m Tc-pertechnetate from a fission based 99 Mo/ 99m Tc generator in the second week of its normal working life. Rhenium-188 is also obtained from alumina based 188 W→ 188 Re generator, and developed technique can also be used for the concentration of 188 Re. Because of the high content of inactive molybdenum in neutron irradiated MoO 3 , large columns containing alumina or gel are needed to produce chromatographic 99 Mo→ 99m Tc generator. This results in large elution volumes containing relatively high 99 Mo breakthrough and low concentrations of of 99m 99m TcO 4- . The decrease in specific volume Tc places a limitation on reconstitution of some kits for 99m Tc radiopharmaceuticals applied in diagnostic nuclear medicine. Hence concentration technique is mandatory for effective utilization of (n,γ) produced 99 Mo/ 99m Tc generators at the start of its life whereas in case of fission 99 Mo/ 99m Tc generator the technique may be quite useful at the end of first week of its life. Post elution concentration of 99m Tc using in house prepared lead (Pb) column was developed. The high bolus volumes (10-60 ml saline) can conveniently be concentrated in ~1 ml of saline. The adsorption behavior of Na 188 ReO 4 is quite different from Na 99m TcO 4 on lead column. Sodium perrhenate did not adsorb on Lead column and found quantitatively in effluent. Thus Lead column may also be used for the separation of Na 99m TcO 4 from Na 188 ReO 4 . The high bolus volumes (20–40 mL) of the generator-produced Rhenium-188 require post elution concentration of the eluate for the preparation of a dissolved β − source and radiopharmaceuticals labeled with Re-188 for radiotherapy. Solvent extractionof 188 Re in methyl ethyl ketone was studied. With the increase of organic phase volume, extraction of 188 Re was enhanced while mixing time of aqueous and organic phases did not show any significant effect on the extractability of 80% of 188 Re in the organic phase. Almost 188 Re was extracted in methyl ethyl ketone at a volume ratio of 1 : 2 for aqueous and organic phases. By evaporation/distillation of methyl ethyl ketone, concentrated and dissolved in the desired volume of physiological saline.
