Introduction: In conventional Laparoscopic Appendicectomy, three ports are used wherein both the subumbilical and supra-pubic port sites are hidden the by the natural camouflages and the only visible scar is the third port in the iliac fossa. The third port scar can be made invisible by using a needle port for trans-parietal appendicular traction. Materials and Methods: From January 2013 to May...

Introduction Single-port laparoscopic surgery has some advantages, including improved cosmetic outcomes and minimized parietal trauma. However, pure single-port laparoscopic rectal cancer surgery is challenging because of the difficulties in creating triangulation and applying the laparoscopic staplers with sufficient distal margins in the narrow pelvic cavity. Recently, a reduced-port robotic ...

Abstract This paper explores theoretically the formation of a system cities in which ports affect spatial location and size cities. We use complex systems economic geography approach to generate 2D cellular automata simulate landscape urban agglomerations based on different configurations port locations. The dynamics model shows emergence classical city-size distributions number their layout af...

The lack of information about core’s internal structure is The designers must rely solely on the test set distributed by the core provider. Sometimes the stuck at fault (SAF) model and automatic test pattern generation (ATPG) are used to generate test vectors for those pre-defined blocks. However, a SAF test set could waste lots of time to verify the pre-verified internal structure of the cores...

The aim of the study was to analyze the treatment effect of transumbilical single-port laparoscopic varicocelectomy (TUSPLV) on recurrent varicocele (VC). In order to compare the surgical effects of TUSPLV to traditional retroperitoneal ligation of the internal spermatic vein, 64 patients with recurrent VC were enrolled and divided into the control group (n=30) and the observation group (n=34)....

Testing two-port 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 as the test strategy. This paper discusses the consequences of the port restrictions (read-o...

Testing two-port memories requires the use of single-port tests as well as special two-port tests; the test strategy determines which tests to be used. Many two-port memories have ports which are read-only or write-only; this impacts the possible fault models, the tests for single-port and two-port memories, as well as the test strategy. This paper presents a test strategy for two-port memories...

The present study was performed to investigate the effect of commercial and operational factors on competitiveness improvement of Shahid Beheshti Port (SBP) in Chabahar in attracting shipping lines. The research method is applied in terms of purpose. Initially, the researcher conducted the qualitative phase to identify important variables, create a typology, or make new theories. To reach the s...

Many methods have been adopted by shipping operators to evaluate, analyze and select ports of calls. Majority of these methods are generally based on evaluating different port performance criteria involved. The ports performance criteria are interrelated and are of a complex nature. Comparison of ports by different evaluation methods provides a basis for implementing operating strategies for...
