Agenda Control In The Indian Parliament And The Impact On Its Oversight Function – Analysis And Evidence, Maansi Verma Dec 2022

Agenda Control In The Indian Parliament And The Impact On Its Oversight Function – Analysis And Evidence, Maansi Verma

Socio-Legal Review

Separation of powers is understood as the diffusion of powers among different branches of the government, with each branch acting as a check on the other. This principle is considered an anti-thesis to totalitarianism, preventing the absolute concentration of power and thus protecting liberty. The Cabinet-style parliamentary form of government, with its genesis in Britain, fused together the executive with the legislature. This resulted in powerful executives and weakened legislatures with limited oversight capabilities. As institutions evolved over time, internal rules and procedures also evolved both as constraints and enablers of executive dominance, by distributing the powers of agenda control. …


‘Private Acts’ And Structural Inequality: Law And Housing Discrimination, Rowena Robinson Dec 2022

‘Private Acts’ And Structural Inequality: Law And Housing Discrimination, Rowena Robinson

Socio-Legal Review

This paper focuses on law and housing discrimination within the context of a sociological understanding of the cumulative disadvantageous effects of what are legally considered ‘private acts’. It therefore brings a distinct perspective to the examination of vertical versus horizontal rights. The paper particularly focuses on housing discrimination against Muslims in urban areas against the background of marginalisation, conflict, and violence. It seeks to think about housing segregation as both producing discrimination, targeted violence, economic inequality, and social exclusion as well as itself being a product of these factors. Public policy in the form of equal opportunities legislation has been …


Women, Gender Politics, And Resistance In Kashmir, Seema Kazi Dec 2022

Women, Gender Politics, And Resistance In Kashmir, Seema Kazi

Socio-Legal Review

This article focuses on Kashmiri women and the gender politics underpinning the August 5, 2019 revocation of Article 370 in Kashmir. Reclaiming Kashmiri women’s property rights was among the justifications cited by the state for revoking Kashmir’s autonomy. Paradoxically, however, most analyses centered on its political implications. Kashmiri women’s opinions regarding the revocation, the state’s use of the women’s rights argument to justify the same, or Kashmiri women’s rights and experiences in the wake of the revocation were seldom the subjects of discussion or analysis. Beginning with a brief overview of Kashmiri women’s role in the Kashmiri struggle, I juxtapose …

Herpes Zoster And Resultant Segmental Zoster Paresis: A Casereport And Literature Reviewarticle, Yen-Jou Ho, Hong-Yi Lin, Yao-Jen Chen

Rehabilitation Practice and Science

Herpes zoster (HZV) is ascribed to the reactivation of the dormant varicella-zoster virus (VZV) in the dorsal root ganglia. The most commonly seen manifestation is a painful skin rash. However, several additional complications have been documented in the literature. A less-mentioned yet severe complication is segmental zoster paresis (SZP), which can cause limb paralysis. SZP's mechanism is still under debate, and a direct invasion of motor fibers due to anatomical adjacency has been proposed. Here we report a patient who had sudden onset of left upper limb paresis and gradually developed a skin rash afterward, which a dermatologist confirmed as …

Integration Of Urban Farming Into City Infrastructure Development, Ayobami Popoola, Bolanle Wahab, Hangwelani Magidimisha Chipungu, Lovemore Chipungu

CSID Journal of Infrastructure Development

The ability to respond to the need for food is threatened by the scarcity of urban farmers (UF) in the elevation of the urban population. This shows that the availability of food is a cultivated land function, indicating that agriculture is only a mirage when sites are unavailable for farming. Irrespective of these conditions, the sustainability of food production within the city spaces is still the complimentary urban infrastructure enhancing the movement of goods and farmers. Therefore, this study aims to determine the patterns of integrating urban farming into city infrastructure development. In this case, a mixed methods approach was …

Platform: A Journal of Engineering

While ionic liquids are usually high in cost, only small amounts are needed to establish their beneficial characteristics combined with the utilization of a cosurfactant. A cationic surface-active ionic liquid, 1-hexadecyl-3- methylimidazolium bromide (C16mimBr) was chosen as the main surfactant because it is non-volatile, non-flammable, and able to withstand high temperature. However, it was studied that this ionic liquid poses a major threat to the aquatic environment, thus another surfactant is needed as a cosurfactant. Lauryl glucoside was used as the cosurfactant because it is environmentally friendly, has low toxicity and excellent biodegradability. The potential of this surfactant mixture for …

Platform: A Journal of Engineering

The Enhanced Oil Recovery (EOR) process has grown within the time oil exploration was conducted, and many recovery methods were invented to maximize production. One of the promising recovery techniques is carbon dioxide (CO2) flooding. However, CO2 flooding has its disadvantages where due to different mobility and heterogeneity between CO2 and reservoir, the sweep efficiency is reduced because of gas channelling and viscous fingering. Thus, the application of surfactant is introduced to solve the problem. But, by using surfactants in CO2 flooding, loss of surfactant to the formation is observed. Due to this setback, the cost of the EOR process …
