The purpose of this study is investigating the chemical analysis of drinking water in Kashan district. This district contained Kashan, Aran and Bidgol and Nooshabad cities and it had an estimated population more than of 400,000 in 2007. 42 Samples were collected during October 2006 to May 2007.The temperature of the water Samples is in the range 25-30°C. The water samples were analyzed for pH ,...

BACKGROUND Malassezia species are lipophilic yeasts found on the skin surface of humans and other warm-blooded vertebrates. It is associated with various human diseases, especially pityriasis versicolor, which is a chronic superficial skin disorder. OBJECTIVES The aim of the present study was to identify Malassezia species isolated from patients' samples affected by pityriasis versicolor, usi...

In this paper we obtain several tight bounds on different types of alliance numbers of a graph, namely (global) defensive alliance number, global offensive alliance number and global dual alliance number. In particular, we investigate the relationship between the alliance numbers of a graph and its algebraic connectivity, its spectral radius, and its Laplacian spectral radius.

BACKGROUND Research has shown that the therapeutic alliance plays an important role in enhancing treatment outcome among individuals with a variety of disorders, including posttraumatic stress disorder (PTSD). However, the therapeutic alliance and treatment outcome has not yet been studied in dissociative disorders (DD). OBJECTIVES The current study sought to investigate the impact of allianc...

We examined the therapeutic alliance in evidence-based treatment for children (N=97, 24 girls and 73 boys, ages 6-13 years) referred clinically for oppositional, aggressive, and antisocial behavior. We predicted that the quality of the child-therapist alliance would be related to therapeutic improvements in the children at the end of treatment and that the alliance would be predicted by allianc...

Let G = (V, E) be a graph and let W:V→N be a non-negative integer weighting of the vertices in V. A nonempty set of vertices S ⊆ V is called a weighted defensive alliance if ∀v ∈ S ,∑u∈N[v]∩S w(u) ≥ ∑x∈N(v)−S w(x). A non-empty set S ⊆ V is a weighted offensive alliance if ∀v ∈ δS ,∑u∈N(v)∩S w(u) ≥ ∑x∈N[v]−S w(x). A weighted alliance which is both defensive and offensive is called a weighted pow...

This research focuses on services based on alliance and devises a novel concept called service alliance. Service alliance uses service as the unit that companies can exchange, furnish, and share services in the alliance. Service alliance emphasizes on the representation and exchange for value of single service from an individual company. This research utilizes game theory to discuss the best ac...

The determinants of strategic alliance performance have not been explored adequately in the literature. Empirical studies abound with numerous kinds of performance measures but, thus far, there is no coherent theoretical basis for the determinants of alliance performance. In this article we present a theoretical framework for understanding alliance performance in terms of its key antecedents. W...

We model the two-Wrm alliance as an iterated prisoners’ dilemma game with an exit option and test several theoretical predictions over two experimental studies. A new major eVect on alliance performance arises by including the exit option (i.e., the option to end the alliance and receive a Wxed payoV that is less than the payoV for mutual cooperation but greater than the payoV for mutual defect...
