background: leiomyomata is the most frequent gynecological neoplasm. one of the major complications of myomectomy is intrauterine adhesion (synechiae). objective: to evaluate and compare the rate and severity of synechiae formation after myomectomy by laparotomy and laparoscopy. materials and methods: in this non-randomized interventional trial, hysteroscopy was performed in all married fertile...

This paper presents a fault location technique for transmission lines with minimum current measurement. This algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. These current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...

    Hub covering location problem, Network design,   Single machine scheduling, Genetic algorithm,   Shuffled frog leaping algorithm   Hub location problems (HLP) are synthetic optimization problems that appears in telecommunication and transportation networks where nodes send and receive commodities (i.e., data transmissions, passengers transportation, express packages, postal deliveries, etc....

In the current competitive conditions, all the manufacturers’ efforts are focused on increasing the customer satisfaction as well as reducing the production and delivery costs; thus, there is an increasing concentration on the structure and principles of supply chain (SC). Accordingly, the present research investigated simultaneous optimization of the total costs of a chain and customer satisfa...

Since, most of the organizations present their services electronically, the number of functionally-equivalent web services is increasing as well as the number of users that employ those web services. Consequently, plenty of information is generated by the users and the web services that lead to the users be in trouble in finding their appropriate web services. Therefore, it is required to provi...

Let $x$ and $y$ be two distinct vertices in a connected graph $G$. The $x,y$-location of a vertex $w$ is the ordered pair of distances from $w$ to $x$ and $y$, that is, the ordered pair $(d(x,w), d(y,w))$. A set of vertices $W$ in $G$ is $x,y$-located if any two vertices in $W$ have distinct $x,y$-location.A set $W$ of vertices in $G$ is 2-located if it is $x,y$-located, for some distinct...

DNA double strand breaks (DSBs) are the most dangerous form of DNA damage and need to be repaired efficiently in order to maintain genomic stability. The kinase ATM becomes activated upon recognition of DSBs and transduces this into cell cycle checkpoint activation and DNA repair. There are two main pathways by which DSBs can be repaired: Non-homologous end joining (NHEJ) and homologous recombi...

At the request of the American Joint Committee on Cancer (AJCC), non-anatomic (non-TNM) classifications were evaluated and important classifications incorporated into staging recommendations for oesophageal cancer in the 7th edition of the Cancer Staging Manual [1]. Cancer location, histopathological cell type and histological grade were demonstrated to enhance cancer staging [2]. Adenocarcinom...
