It is common in many countries that engineers having an academic degree in Civil Engineering are appointed responsible for different tasks related to Bridge Engineering. However, there are serious questions about whether formal university courses in civil engineering could cover the needs of a bridge engineer to fulfill his or her job successfully. Regarding the recent significant advances in t...

In this study, access flow in hemodialysis patients with bridge grafts was measured by a newly developed device. The technique is based on the measurement of changes in the ultrasound characteristics of blood. These changes were initiated by an injection of isotonic saline and measured in the tubes of the extra-corporeal circuit. The access flow rate (mean +/- standard variation) was 880 +/- 44...

We show that every bridgeless graph of maximum degree ∆ has a spanning d(∆ + 1)/2e-walk. The bound is optimal.

We review some techniques of resummation applied to heavy quark production in hadronic scattering and electroproduction near partonic threshold, and discuss the reduction of factorization scale dependence in resummed cross sections.

Venous access is the foundation for safe and effective hospital-based care. Inpatient providers must have a deep knowledge of the different types of venous access devices (VADs), their relative indications, contraindications, and appropriateness. However, such knowledge is difficult to come by and usually only gleaned through years of clinical experience. To bridge this gap, we provide an in-de...

This paper presents the comparative study of three phase twenty five level diode clamped and cascaded H-bridge multilevel inverters. The comparison is made in respect of requirement of devices, quality of output voltage and reduction of total harmonic distortion at the multilevel inverter terminals. In this work multicarrier sinusoidal pulse modulation control methods of Phase disposition (PD-P...

This article investigates the approaches of the various discourses operating in the water sector and how they address the issues of scarcity and equitable access under projected climate change impacts. Little synergy exists between the different approaches dealing with these issues. Whilst being a sustainable development and water resources management issue, a holistic view of access, scarcity ...

Access control is a mechanism for achieving confidentiality and integrity in software systems. Specifying access control policies (ACPs) is a complex process that can benefit from requirements engineering techniques. In this paper, we present a method for deriving access control policies from software requirements specifications (SRS) and database designs. The approach provides prescriptive gui...

The purpose of this pilot study was to explore the experience with computers and the meaning of computers to a group of homeless men living in a long-term shelter. This descriptive exploratory study used semistructured interviews with seven men who had been given access to computers and had participated in individually tailored occupation based interventions through a Work Readiness Program. Th...
