Intimate Partner violence is not a culturally limited practice, but prevails in every country, irrespective of culture, class, and ethnicity. Violence is one of the mechanisms used by men to control and subjugate women; and is a manifestation of unequal power relationship sustained by patriarchy. Patriarchy makes violence necessary for the sake of its existence. Intimate partner violence, the most common forms of gender-based violence entails the exertion of power over a partner in an intimate relationship through a behavior that is intimidating, threatening, harassing or harmful. The spouse can be harmed physically, as well sexually, emotionally, and psychologically, the violence can occur multiple times. Intimate partner violence in Pakistan persists almost in every family because women have subjugated and vulnerable status and are generally treated as second class citizens. Generally, the occurrence of violence at home is effectively condoned and regarded it as ‘private matter’ which does not require any intervention. it is seldom recognized as a crime socially unless it takes an extreme form of murder or attempted murder which could range from driving a woman to suicide or engineering an accident (frequently the bursting of a kitchen stove). This study aims to find out the factors which precipitate Intimate partner violence in Pakistan and what are the factors which preclude the reporting of Intimate partner violence and seeking legal redress. This study has found that strict cultural and patriarchal system and values precipitate intimate partner violence and also preclude victims to report the incidences by not giving them appropriate moral, cultural and legal support.

This paper presents a computer simulation showing how the gear contact ratio affects the dynamic load on a spur gear transmission. The contact ratio can be affected by the tooth addendum, the pressure angle, the tooth size (diametral pitch), and the center distance. The analysis presented in this paper was performed by using the NASA gear dynamics code DANST. In the analysis, the contact ratio was varied over the range 1.20 to 2.40 by changing the length of the tooth addendum. In order to simplify the analysis, other parameters related to contact ratio were held constant. The contact ratio was found to have a significant influence on gear dynamics. Over a wide range of operating speeds, a contact ratio close to 2.0 minimized dynamic load. For low-contact-ratio gears (contact ratio less than two), increasing the contact ratio reduced gear dynamic load. For high-contact-ratio gears (contact ratio equal to or greater than 2.0), the selection of contact ratio should take into consideration the intended operating speeds. In general, high-contact-ratio gears minimized dynamic load better than low-contact-ratio gears.

Unconsolidated Porous Media

During CO2 storage, CO2 plume mixes with the water and oil present at the reservoir, initiated by diffusion followed by a density gradient that leads to a convective flow. Studies are available where CO2 convective mixing have been studied in water phase but limited in oil phase. This study was conducted to reach this gap, and experiments were conducted in a vertically packed 3-dimensional column with oil-saturated unconsolidated porous media at 100 bar and 50 °C (representative of reservoir pressure and temperature conditions). N-Decane and crude oil were used as oils, and glass beads as porous media. A bromothymol blue water solution-filled sapphire cell connected at the bottom of the column was used to monitor the CO2 breakthrough. With the increase of the Rayleigh number, the CO2 transport rate in n-decane was found to increase as a function of a second order polynomial. Ra number vs. dimensionless time τ had a power relationship in the form of Ra = c×τ−n. The overall pressure decay was faster in n-decane compared to crude oil for similar permeability (4 D), and the crude oil had a breakthrough time three times slower than in n-decane. The results were compared with similar experiments that have been carried out using water.
