The subsea jumper has become an essential part of production systems as a gas–liquid mixing pipeline connecting the end manifold (PLEM) to Christmas tree. During oil and gas transportation, common flow pattern, alternating characteristics slug easily cause vibration, resulting in instability or fatigue damage. present study investigates experimentally numerically M-shaped its induced vibrations...

In this research, the convective heat transfers of turbulent water fluid flow in alternating oval tubes is studied using computational fluid dynamics. The purpose of the study is to analyze the heat transfer enhancement and secondary internal flows under different alternate angles. Also, comparing the effect of two schemesfor the domain discretization to be used in the soluti...

Online media undermines the authority of religious preachers because many online users feel obligated to do da'wah (preaching) even though they not have capacity for knowledge. provides easy facilities sharing with people and groups one click. The distribution this content such as writing, images or videos is done on various platforms including WhatsApp group (WAG) often without considering sui...

the growth of the electrical energy consumption form one side and the bounded available fossil fuel and other limitations from the other side, makes the thermal power plants upgrading as a main demand in the world. decreasing the internal energy consumption, increasing the performance and the output power with the minimum costs are the important targets of the power plants retrofitting. nowaday...

Influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.Observations show that without a vent hood, there is a downward gas flow in theflu...

This paper outlines the prominence of home care for disabled people in the UK and Wales before introducing the debate surrounding paying for such services. It will then give an overview of policy developments in this area since 1997, including the Royal Commission on Long Term Care (Sutherland, 1999), the introduction of free personal care in Scotland following devolution, in 2001 and the failu...

Since devolution in 1998, the Welsh Assembly Government (WAG) has been proactive in exercising its responsibilities for equalities within its territories (Chaney, 2009; Davies, 2003). The Government of Wales Act 2006 moreover, placed a statutory duty on the Assembly to have due regard for equality of opportunity in everything it did. Although discrimination law in itself is not a function that ...
