Laparoscopic cholecystectomy has virtually replaced conventional open cholecystectomy as the gold standard for symptomatic cholelithiasis. The laparoscopic approach brings numerous advantages at the expense of higher complication rates, especially in training facilities. This comparative 18-month review examines the outcomes of 52 cholecystectomies performed by a single surgical resident at the...

We present a mathematical model for a dynamic Delphi survey method which takes advantages of Web technology. A comparative study on the performance of the conventional Delphi method and the dynamic Delphi instrument is conducted. It is suggested that a dynamic Delphi survey may form a consensus quickly. However, the result may not be robust due to the judgement leaking issues.

Analysis techniques. All these techniques and algorithms have their advantages and limitations. This proposed paper discusses various techniques and transformations proposed earlier in literature for extracting feature from an ECG signal. In addition this paper also provides a comparative study of various methods proposed by researchers in extracting the feature from ECG signal.

This paper describes a comparative investigation of two spectral momentbased identification procedures with each other and with the method of maximum likelihood. The case considered is that of a bilinear system. Analyses making use of secondand third-order moments are presented. Inputs investigated are pulse, pulsepair and stochastic. Some of the relative advantages and disadvantages of each es...

INTRODUCTION Video-assisted thoracoscopic surgery (VATS) has gained enormous acceptance among pediatric surgeons. However, most studies on advantages of VATS do not reach a high level of evidence. According to a recent classification of the Oxford Centre for Evidence-Based Medicine (CEBM), studies can be classified into Levels 1 to 5 in order of descending quality. We aimed to identify comparat...

Amisulpride is an atypical antipsychotic drug with a unique receptor pharmacology which is dose dependent. It is a standard treatment in dysthymia as well as in psychosis. Amisulpride is efficacious, effective and well tolerated in positive symptoms of schizophrenia: there is extensive evidence that it treats negative symptoms when given in low doses, although relative lack of EPS and an antide...

We critically assess the comparative efficiency advantages and disadvantages of capitalist cooperative firms using team production as a frame reference. revisit debate about such (dis...

Many studies have shown that being bilingual presents an advantage in executive control. However, it appears that knowing two (or more) languages is not enough to improve executive control. According to the adaptive control hypothesis (Green and Abutalebi, 2013), the interactional context in which bilinguals behave is a key factor that modulates cognitive advantage in executive control. Transla...

It was a hot humid morning as always in the small village of Amokwasuaso in Ghana’s western region. We sat in the small, dilapidated community meeting hall awaiting the arrival of a World Bank fact-finding mission. The Amokwasuaso community has achieved some celebrity in Ghana as the first community to have the rights to manage wildlife devolved to its residents by the State. The fact-finding m...

Polyacrylamide gel electrophoresis (PAGE), which is widely used to assess protein purity and molecular weight [1], is best combined with a highly sensitive, reproducible, inexpensive, rapid, and easy to perform protein staining/detection method. Coomassie brilliant blue (CBB)1 staining is a popular method, known for its simplicity, economy, and compatibility with downstream analysis but relativ...
