Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...

modeling, representation, analysis Model making and manipulation, conscious or unconscious plays a major role in all of our lives. All of us perceive the world and the day to day problems we need to solve through the filters of internal models, and for better or worse, these filters affect all aspects of our interactions and our decision making. Externalising those models, either formally or in...

Component-based software engineering means constructing new systems from already existing, service-providing components. Object-based software engineering means constructing a new system in terms of interacting, distinct units of information and services called objects. Both components and objects have encapsulation properties and are accessed via well-de ned interfaces. Both components and obj...

The early modern debates on the nature of space enjoy a renewed interest in the recent philosophical literature. Focal points of the discussion are the opposition between the “absolute” vs. the “relational ” conception of space and the related issue of its presumed substantival nature. Quintessential formulations of the key positions in the debate remain the viewpoints attributed to Newton and ...

This paper demonstrates the relativity of Computability and Nondeterministic; the nondeterministic is just Turing's undecidable Decision rather than the Nondeterministic Polynomial time. that is equivalent of the Polynomial time and actual time; it redefines the NTM based on its undecidable set of its internal state. It comes to the conclusions: The P-­‐reducible is misdirected from the Turing ...

Background: Using of natural and synthetic surfactant is a rescue treatment for respiratory distress syndrome. In Iran, Survanta and Curosurf are the most frequent used natural surfactant preparations. We compared the clinical response and safety of two surfactants poractant alpha (Curosurf) and beractant (Survanta) for treatment of respiratory distress syndrome (RDS) in preterm infants. Method...

Background and Aims: Several studies have shown that host genetic factors can be associated with the risk of developing Helicobacter pylori infections. Therefore, we evaluated the most prevalent toll-like receptors (TLRs) polymorphisms in Helicobacter pylori positive subjects and their possible role in susceptibility to Helicobacter pylori infections. Materials and Methods: Using related keywo...
