Muslim Women’s Right to Divorce and Gender Equality Issues in Bangladesh: A Proposal for Review of Current Laws

In Bangladesh, sharia law goes hand in hand with the statutory laws of the land. These laws are both conjointly used to regulate and monitor the issues of divorce among Muslims of the country. Orthodox Islamic laws provide husbands with the authority of issuing divorce or talaq to their wives known as Talaq-e-Tawfiz (popularly known as tawfiz) in the kabinnama (the written document of the contract of marriage). Women’s power to exercise the tawfiz, however, depends solely on the will of their husbands. Although Muslim women are capable of repudiating their marriages by the process of khula or mubarat, these are only executable under the free consent of their husbands. Also, the statutory laws of Bangladesh address Muslim women’s right to the dissolution of marriage by the intervention of the court, only under several grounds. The traditional interpretation of sharia law and the statutory laws of the country are both unwilling to establish Muslim women’s absolute right to renounce marriage as with their male counterparts. Current research reveals that this violation of gender equality and women’s rights generates female subordination in society and gives birth to numerous socio-legal complications

The impact of direct nucleation control on crystal size distribution in pharmaceutical crystallization processes

The control of crystal size distribution (CSD) in pharmaceutical crystallization is of primary importance, as downstream processes such as filtration or drying are greatly affected by the properties of the CSD. It is recognized that the variability in the final CSD is mainly caused by the significant uncertainties in the nucleation rates, and therefore, a good control of nucleation events is necessary to achieve the desired CSD. In this paper, a new direct nucleation control (DNC) approach is introduced that directly controls the apparent onset of nucleation defined as the formation of new particles with detectable size using in situ instruments. The approach uses information on nucleation and dissolution, provided by focused beam reflectance measurement (FBRM), in a feedback control strategy that adapts the process variables, so that the desired quality of product is achieved, for example large crystals with a narrow CSD. In addition, DNC provides in situ fines removal through the operating protocol, rather than having additional equipment and external recycle loops. DNC does not require concentration measurement and has the advantage of being a model-free approach, requiring no information on nucleation or growth kinetics in order to design an operating curve. The DNC approach automatically and adaptively detects the boundary of the operating zone; hence it is more robust to the presence of impurities or residual solvent than the supersaturation control approach. The approach has been applied for the crystallization of glycine and experimental results demonstrate the benefits of DNC of producing larger crystals with narrower CSD compared to classical operations

Mechanical and thermal properties of montmorillonite-reinforced polypropylene/rice husk hybrid nanocomposites

© 2019 by the authors. In recent years, there has been considerable interest in the use of natural fibers as potential reinforcing fillers in polymer composites despite their hydrophilicity, which limits their widespread commercial application. The present study explored the fabrication of nanocomposites by melt mixing, using an internal mixer followed by a compression molding technique, and incorporating rice husk (RH) as a renewable natural filler, montmorillonite (MMT) nanoclay as water-resistant reinforcing nanoparticles, and polypropylene-grafted maleic anhydride (PP-g-MAH) as a compatibilizing agent. To correlate the effect ofMMTdelamination andMMT/RHdispersion in the composites, the mechanical and thermal properties of the composites were studied. XRD analysis revealed delamination of MMT platelets due to an increase in their interlayer spacing, and SEM micrographs indicated improved dispersion of the filler(s) from the use of compatibilizers. The mechanical properties were improved by the incorporation of MMT into the PP/RH system and the reinforcing effect was remarkable as a result of the use of compatibilizing agent. Prolonged water exposure of the prepared samples decreased their tensile and flexural properties. Interestingly, the maximum decrease was observed for PP/RH composites and the minimum was for MMT-reinforced and PP-g-MAH-compatibilized PP/RH composites. DSC results revealed an increase in crystallinity with the addition of filler(s), while the melting and crystallization temperatures remained unaltered. TGA revealed that MMT addition and its delamination in the composite systems improved the thermal stability of the developed nanocomposites. Overall, we conclude that MMT nanoclay is an effective water-resistant reinforcing nanoparticle that enhances the durability, mechanical properties, and thermal stability of composites
