Arbitration: Legislation, Scope, and Functioning in Pakistani Legal System a Pragmatic Approach in Law and Sharī‘ah

This study investigates the case of arbitration in the modern states in general and in the Islamic Republic of Pakistan in particular, as a self-binding, amicable mode of Alternative Dispute Resolution (ADR). It starts with arbitration’s meaning, history and evolutional background and discusses them as preliminaries and entrance to the main topic. The study debates Pakistani legislation on the subject, with special focus on the Arbitration Act, 1940. It examines the functioning of arbitration in Pakistani legal system, detects the flaws and areas of improvement therein, and most significantly, suggests proposals for required amendments in the relevant laws. In this connection, the equivocal nature of ADR provisions in some statutes other than Arbitration Act, has been specially highlighted.  As per requirement of the Article 2(A) of the Constitution 1973, some inconsistencies of the laws on the subject with Sharī‘ah have also been traced. The issue of qualifications of arbitrators (hakams) has been detected as the main subject of inconsistency between law and Sharī‘ah, resulting in substantial and effective bearings. A similar inconsistency, comparatively with a lesser effect, has been noted in arbitration of family disputes regarding fixation of number of arbitrators and the hail from families of the disputing spouses. While investigating all these issues, an analytical-cum comparative strategy has been followed. The conclusion contains a concise brief on comparison between Sharī‘ah and law on the subject and a package of proposed amendments in the gray areas.

Synthesis, Characterization and Applications of Lanthanide Nano Particles Doped on Zno, Tio2, Sio2.

Three sets of nanoparticles (ZnO, Gd/ZnO, Sm/ZnO, La/ZnO), (TiO2, Gd/TiO2, Sm/ TiO2, La/TiO2) and (SiO2, Gd/SiO2, Sm/SiO2, La/SiO2) were fabricated by sol-gel method using appropriate precursors with and without using surfactant (Sodium Dodecyl Sulphate)below its CMC value. The synthesized samples were characterized by Thermo gravimetric Analysis/Differential scanning calorimetry (TGA/DSC) for their thermal properties, by scanning electron microscopy (SEM) for morphology of nanoparticles, by Transmission electron microscopy (TEM) for particle size, by X-Ray Diffraction (XRD) for crystal structure and crystallite size, and Fourier Transform Infrared Spectroscopy (FTIR) was used to analyze metal-oxygen bonding and functional groups. All characterization techniques confirmed the synthesis of nanoparticles. The average size of all nanoparticles was observed below 30nm and results obtained from TEM and XRD for particle size are in agreement with each other. Solid phase UV-visible absorption spectrophotometer (SPS) analysis was performed to study optical band gap of metal oxide nanoparticles and effect of doping on the band gap of nanoparticles. It was observed that band gap of undoped nanoparticles were higher than the band gap of same material in bulk form and band gap of lanthanide doped nanomaterials was less than undoped material. The observed optical band gap value for ZnO was 3.62eV, for TiO2 was 3.69eV and for SiO2 was 3.58eV. Catalytic activity was done by photodegradation of a highly neurotoxic, industrial pollutant Methylene Blue at different reaction conditions for time intervals 30 minutes, 60 minutes and 120 minutes using UV-light, Sunlight and dark. The photocatalytic degradation of MB was studied by using UV-Vis spectrophotometer in kinetic mode and first order rate constant (k) was calculated. Maximum degradation (26.146%) with k-value 0.1031 Sec-1was made Gd/ZnO nanoparticles after 120 minute reaction in UV-light. It was also observed that photodegradation activity of Gd/ZnO, Sm/ZnO and Sm/TiO2 was approximately equal with a slight difference. Also SiO2 and Ln (Ln= Gd,Sm,La) doped SiO2 have lower catalytic degradation activity as compared to (ZnO, Gd/ZnO, Sm/ZnO, La/ZnO) and (TiO2, Gd/TiO2, Sm/ TiO2, La/TiO2). Results suggested that these nanoparticles may be envisaged for the treatment of waste water.
