BACKGROUND single-port laparoscopic surgery has gained popularity over the last decade. This technique is used for several surgical procedures. This paper documents a new and cheaper access method known as "surgical glove port" or "homemade single-port", and describes our initial experience with 25 cases. METHOD Eleven cholecystectomies, eight totally extraperitoneal inguinal hernia repairs, ...

Port Knocking is an important concept to secure services provided by the servers. By a predefined port knocking sequence server identify whether the request is a legitimate request for a service. This paper presents an analyzing the network security concept of Port Knocking and assesses their suitability as firewall authentication mechanisms for opening network ports or performing certain actio...

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...

BACKGROUND For many years, subcutaneous therapeutic port system was known as a major route to access central veins. However, significant complications have been reported through recent years. One of the most important complications of subcutaneous port implantation is skin necrosis. In order to decrease this complication, we would like to introduce subpectoral fascia port implantation through t...

The economizer principle is a well-known method to reduce the expansion losses of a refrigeration system. The alternative refrigerant CO2 has a relatively large isentropic exponent. Therefore it has a high potential for raising efficiency by application of this principle. Reciprocating piston compressors are favored for CO2 refrigeration applications due to their small sealing length and theref...

Port Lincoln, South Australia is the departure port for the only white shark, Carcharodon carcharias, cage dive industry in Australia. Established in the early 1960’s as a niche tourism venture, the industry has recently undergone a rapid expansion to accommodate greater passenger numbers, more tourism operators, and additional infrastructure aimed at capturing a greater proportion of the touri...

In this paper, an area-efficient decoder architecture is proposed for the quasi-cyclic low-density parity check (QC-LDPC) codes specified in the IEEE 802.16e WiMAX standard. The decoder supports all the code rates and codeword lengths defined in the standard. In order to achieve low area and maximize hardware utilization, the decoder utilizes 4 decoding function units, which is the greatest com...

The main objective of this work is to develop and evaluate the performance of a new PK technique, which can avert all types of port attacks and meets all network security requirements. The new technique utilizes three wellknown concepts, these are: port-knocking (PK), steganography, and mutual authentication, therefore, it is referred to as the hybrid port-knocking (HPK) technique. It can be us...

A two-port memory contains two duplicated sets of address decoders, which operate independently. Testing such memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests have to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible tests for single-port and two-port memories, as well...
