Background and aims: Hazard identification is a critical factor to ensure safe design and operation of systems in the process industries. Process industries are one of the most complex systems, with a variety of equipment, control systems, and executive procedures. In these industries, the use of hazardous materials as raw materials or products is quite common. Interactions between technical co...

This paper presents a preliminary study on the system reliability for the geotechnical design of braced excavations in soft clays. In this system reliability geotechnical analysis, both ultimate limit state (ULS) and serviceability limit state (SLS) are considered. Herein, the ULS failure refers to the basal heave failure, while the SLS failure refers to failures sue to excessive ground-surface...

Previous mapping studies have revealed that the frequency and large size of inverted repeat junction shifts in Apiaceae plastomes are unusual among angiosperms. To further examine plastome structural organization and inverted repeat evolution in the Apiales (Apiaceae + Araliaceae), we have determined the complete plastid genome sequences of five taxa, namely Anthriscus cerefolium (154,719 base ...

Abstract background and aims: Nowadays the growing complexity of technology and industry has led to vast changes over the last few decades. These changes, in addition to their positive and valuable effects, have also caused industrial accidents affecting human life and the environment. According to the ILO 2011 report, there are 340 million annual workplace accidents and 160 million occupation...

Chronic obstructive pulmonary disease (COPD) affects more than 250 million people around the world. In addition to daily symptoms and functional limitation, living with COPD are susceptible acute deteriorations in respiratory health. People say that these exacerbations most disruptive aspect of their frequent associated rapid progression, impaired quality life, excess mortality. Exacerbations t...

Background: A malaria vaccine could be an important addition to current control strategies. We report the safety and vaccine efficacy (VE) of the RTS,S/AS01 vaccine during 18 mo following vaccination at 11 African sites with varying malaria transmission. Methods and Findings: 6,537 infants aged 6–12 wk and 8,923 children aged 5–17 mo were randomized to receive three doses of RTS,S/AS01 or compa...

We study a twoband Hamiltonian for hybridized and correlated bands of sc and bcc symmetry, the latter case approximating a twodimensional band. Magnetic phase diagrams are obtained, showing in the bcc case a region of rapid phase change with filling which is absent in the sc case. We consider a twoband system described by the b z -2(A,+B,) following Hamiltonian in the site representation: (3) c...

ions and let expressions. Any such renaming is permitted so long as we avoid clashes with free variables. The nal group of structural rules in Figure 5 is closely modeled on the typing rules for OP and can be used to describe the reduction of subterms within a given term. 3.3 Equalities between terms The rules in Figure 6 de ne the equality relation for terms in OP as the transitive, symmetric ...

The elbow is a congruent joint with high degree of inherent stability, provided by osseous and soft-tissue constraints; however, when substantial lesions these stabilising structures happen, instability the occurs. Significant improvements in surgical diagnosis treatment have been recently introduced both for acute chronic cases. Specific stress tests, clinical practice, different imaging techn...

enemy” in the minds of South Korean conservatives who returned to power in 2008 rather than a real general in the 1950s. This film differs from post-1990 war films by clearly establishing the fact that the Korean War was an invasion of the South by the North, not unlike Cold War anticommunist films, but is more anti-North Korean than anticommunist by presuming that the “enemy” is the Supreme Le...
