The obturation with GuttaFlow Bioseal (GFB) in curved root canals is not clearly investigated due to the new generation of root filling material. This study compared the obturated surface area, extrusion of root filling material beyond the apical foramen and duration of obturation procedure in curved root canals using monocone obturation technique.

Since the administrative contract is concluded with the intention of achieving the public interest, this is one of the most important legal and legal guarantees for fulfilling the contracts, unlike the civil contract which is controlled by the principle of relativity of the effects of the contract based on the private interest of the contractors, a

Group B streptococcus (GBS) is a leading cause of maternally acquired invasive infections in neonates. Maternal immunization with GBS vaccine is of utmost demand for prevention of these infections. Required knowledge concerning vaccine candidates includes serotype-specific polysaccharides and GBS virulence proteins. This study aimed to undertake ca

With the advancement of technology, the ways human communicates and interacts with each other have changed exponentially, where face to face or physical meetings and contacts can now be replaced with google meet, emails, video conferencing, digital signature etc. in ensuring that the proposed or intendedaffairs are successfully done but is no less

Membrane distillation (MD) desalination is an emerging technology for fresh water production. This process incorporates phase change and transport of vapour through a hydrophobic membrane due to difference in vapour pressure across the membrane. The results from experimental studies and the 1 dimensional transport analyses of the heat and mass tran

In this study, sulphuric acid (H2SO4) was used in the pretreatment of sludge palm oil for biodiesel production by an esterification process, followed by the basic catalyzed transesterification process. The purpose of the pretreatment process was to reduce the free fatty acids (FFA) content from high content FFA (N23%) of sludge palm oil (SPO) to a

A solar assisted heat-pump system has been developed to provide cooling, water heating and drying. The energy required for the system is met by a combination of energy collected from the sun, ambient and the energy recovered from a vapor compression heat-pump system, which also serves as an air-conditioner. The presence of evaporator-collector, whi

Three different types of photovoltaic solar cells were installed and connected in grid-tie inverters to run a blower or pump under the meteorological conditions of Singapore. Experiments were performed over a period of time, where all three types of cel1s, each type having a rated power of 360W, were exposed to same enviromental conditions. For a d

A solar assisted heat pump drying system has been designed, fabricated and tested. The performance of the system has been investigated under the meteorological conditions of Singapore. This paper presents an economic optimization of a solar assisted heat pump drying system. Economic viability of solar energy heating systems is usually made by compa

This paper describes a method of economic optimization of an integrated solar heat pump system for space cooling, water heating and drying. The system can serve three functions simultaneously or independently. A simulation model for this system was developed to study the influence different variables. The results were validated by a series of exper
