Aim: To determine the safety and benefits of single port laparoscopic cholecystectomy. Materials and methods: A search for randomized controlled trials comparing single port laparoscopic cholecystectomy with conventional laparoscopic cholecystectomy was conducted using Google scholar, HighPress and SCOPUS. Results: Single port laparoscopic cholecystectomy has a longer operating time, with equiv...

Career anchors development management results in job satisfaction, professional commitment, and higher effectiveness. The purpose of this study was to determine different dimensions of career anchors among in the personnel of vice-chancellor offices of Shiraz University of M...

The KB-5 high pressure gas burners were popularly and widely used in Thailand. This research was aimed to study the influence of four significant parameters, namely degrees of outer and inner ports and the number of outer and inner ports of high pressure gas burners, to the thermal efficiency by the experiments. The thermal efficiency was tested with reference to the standard industrial stoves ...

We analyze an optical three-port reflection grating by means of a scattering matrix formalism. Amplitude and phase relations among the three ports, i.e., the three orders of diffraction, are derived. Such a grating can be used as an all-reflective, low-loss coupler to Fabry-Perot cavities. We derive the input-output relations of a three-port grating coupled cavity and find distinct properties t...

The recent literature on ports and regional development mostly documents the weakening spatial fix of flows and the negative externalities of ports on their surrounding territories. Except for port impact studies that remain difficultly comparable across locations, such observations are mostly based on simplified measures of port activity, such as total port throughputs, and on developed countr...

Port hopping is a typical proactive cyber defense technology, which hides the service identity and confuses attackers during reconnaissance by constantly altering service ports. Although several kinds of port hopping mechanisms have been proposed and implemented, but it is still unknown how effective port hopping is and under what circumstances it is a viable moving target defense because the e...

Empirically validated psychosocial therapies for individuals diagnosed with schizophrenia were described in the report of the Schizophrenia Patient Outcomes Research Team (PORT, 2009). The PORT team identified eight psychosocial treatments: assertive community treatment, supported employment, cognitive behavioral therapy, family-based services, token economy, skills training, psychosocial inter...

ÐThis paper begins with an overview of realistic fault models for dual-port memories, divided into single-port faults and faults unique for dual-port memories. The latter faults cannot be detected with the conventional single-port memory tests; they require special tests. A precise notation for all faults, such that ambiguities and misunderstandings will be prevented, has been emphasized. Next,...

Dry port is an inland intermodal terminal directly linked by road or rail to a seaport as a center for the transshipment of sea freight to inland destinations. However roads contribute to pollution more than rail. For sustainable transportation systems, we need to improve the performance of rail dry port systems. The purpose of this research is to propose a diagnostic system for modeling and cl...
