Traditionally, the port management model has been characterized by the presence of a centralized public agent in charge of the long run planning and provision of most of the port services. Nowadays, in many cases the need to adjust public expenditure has motivated the search for the active participation of the private sector in many countries, not only for the provision of port services but als...

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...

Objective: The objective of this research is to examine PCB compounds in the Persian Gulf in the Southern Pars area. Methods: In the research, 6 stations were sampled: Asalouyeh Port, Kangan Site, Mehr Petro Kima Petrochemical, 4th Refinery in Southern Pasr, Taheri Port and Aria Sasol Polymer. To sample water in the stations determined, one-liter sampling bottles of dark glass were used. In eac...

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...
