OBJECTIVES The objective of this study is to reach a model defining factors precipitating short survival in patients with oesophageal varices and improving the understanding of such factors. Models would help to prioritize the clinical goals and intervention for saving the lives of patients. METHODS Retrospective analysis of all patients admitted to King Abdul Aziz University Hospital who had...

Dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. These walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. In this research intermediate dual system of steel moment frame was chosen with int...

The integer-order delay of proportional–integral multi-resonant-type repetitive control (PIMR-RC) cannot provide excellent performance for grid-tied inverters when the grid frequency fluctuates. To address this issue and reduce errors, a fractional PIMR-RC (FD-PIMR-RC) scheme is proposed. In addition, to computational load memory consumption, Farrow-structure (FFD) filter adopted. digital with ...

By combining a transmission line system (TLS) and reverberation chamber (RC), hybrid electromagnetic compatibility (EMC) testing facility is designed constructed. Generally, the lowest usable frequency (LUF) of an RC limited by its dimension, which limits application RCs for EMC at low frequencies. Therefore, to improve field uniformity (FU) frequencies lower than LUF, TLS integrated into RC. A...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

Powerful rate-compatible codes are essential for achieving high throughput in hybrid automatic repeat request (ARQ) systems for networks utilising packet data transmission. The paper focuses on the construction of efficient rate-compatible low-density parity-check (RC-LDPC) codes over a wide range of rates. Two LDPC code families are considered; namely, regular LDPC codes which are known for go...

Quiescent nuclei from differentiated somatic cells can reacquire pluripotence, the capacity to replicate, and reinitiate a program of differentiation after transplantation into amphibian eggs. The replication of quiescent nuclei is recapitulated in extracts derived from activated Xenopus eggs; therefore, we have exploited this cell-free system to explore the mechanisms that regulate initiation ...

OBJECTIVES To describe perceptions of chronic care among diabetes patients 6 years after diagnosis by screening and to examine the impact of intensive treatment on patients' perceptions of chronic care. METHODS The ADDITION-Denmark (2001-2006) trial compared the effects of intensive multifactorial therapy (IT) with routine care (RC) among individuals with screen-detected diabetes. Perceptions...

The oscillatory behavior of the cephalopod giant axons in response to an applied current has been established by previous investigators. In the study reported here the relationship between the familiar "RC" electrotonic response and the oscillatory behavior is examined experimentally and shown to be dependent on the membrane potential. Computations based on the three-current system which was in...

This paper focused on energy consumption and carbon emission for heating and cooling during a building’s operation stage, and examined the energy effects of using Cross Laminated Timber (CLT) as an alternative building material to reinforced concrete (RC) in China’s 31 key cities located in different climate zones. The authors designed two seven-story residential buildings, which were construct...
