Purpose: Propofol is one of the most common drugs used in anesthesia induction and the pain during its intravenous injection is one of the most important side effectsthat it has. Therefore, many methods and drugs have been examined so far to reduce or eliminate this side effect. In this study a lot the effects of Alfentanil, Magnesium Sulfate and Ketamine drugs on reducing the pain during i...

Paradigm shift in language education has caused many countries including Iran to reshuffle their public EFL educational program. However, such a promising trend in Iran has entailed serious challenges, which necessitated this study aimed at collecting data from 70 teachers and 70 students to investigate the CLT challenges in terms of both teachers' pedagogical and assessment areas. A Partial Le...

BACKGROUND This study was designed to investigate the effect of metformin and flutamide alone or in combination with anthropometric indices and laboratory tests of obese/overweight PCOS women under hypocaloric diet. METHODS This single blind clinical trial was performed on 120 PCOS women. At the beginning, hypocaloric diet was recommended for the patients. After one month while they were on t...

Action languages allow to formally represent and reason about actions in a highly declarative manner. In recent work, revision and management of conflicts for domain descriptions in such languages wrt. semantic integrity constraints have been considered, in particular their reconciliation. However, merely ad hoc tests and methods have been presented to aid the user in analyzing and correcting a...

This paper evaluates and compares the retrieval effectiveness of eleven search models applied to four test collections written in the French, Portuguese-Brazilian, Hungarian and Bulgarian languages. For the latter two languages, we also compare wordbased and 4-gram indexing schemes. Applying four statistical tests and two ad hoc rules, we analyze the performance levels obtained in order to dete...

In Extreme programming unit testing is organized so that the unit tests are written before coding commences. For many programmers the selection of the test cases is something of an ’ad hoc’ process. Where programmers are experienced in writing test sets it is common for them to use white box or structural test techniques. However, these rely on the structure of the code being available which is...

The ensemble machine learning methods incorporating random subspace and random forest employing genetic fuzzy rule-based systems as base learning algorithms were developed in Matlab environment. The methods were applied to the real-world regression problem of predicting the prices of residential premises based on historical data of sales/purchase transactions. The accuracy of ensembles generate...

Most panel unit root tests are designed to test the joint null hypothesis of a unit root for each individual series in a panel. After a rejection, it will often be of interest to identify which series can be deemed to be stationary and which series can be deemed nonstationary. Researchers will sometimes carry out this classi.cation on the basis of n individual (univariate) unit root tests based...
