a case of tropical eosinophylia which seems to be an independent disease is described. the patient was admitted because of fever, loss of weight- ~and some respiratory disorders. the blood examination shows a high percentage of eosinophylia in several times. in this view other causes of the blood eosinophylia were eliminated by the laboratory tests. the patient was treated with arsenical drugs ...

background listeria monocytogenes has been isolated from various foods and environments in temperate areas, tropical countries and different parts of iran. the bacterium as a psychrotrophic organism is capable of growth at refrigeration temperatures. objective the current study was conducted to determine the incidence of listeria spp. on the surfaces of domestic refrigerators in ahvaz city as a...

Freshwater eels are important animals because they have a unique catadromous life history and are used as food resources. European, American and Japanese eel populations now are considered to be outside the safe biological limits and are seriously threatened with extinction. Therefore, the European eel was recently categorised as critically endangered by the European Union and the United Nation...

In many tasks related to reasoning about consequences of a logical theory, it is desirable to decompose the theory into a number of components with weakly-related or independent signatures. This facilitates reasoning when the signature of a query formula belongs to only one of the components. However, an initial theory may be subject to change due to execution of actions affecting features ment...

In this paper we consider updates that are specified as rules and consider simple knowledge bases consisting of ground atoms. We present a translation of the rule based update specifications to extended logic programs using situation calculus notation so as to compute the updated knowledge base. We show that the updated knowledge base that we compute satisfies the update specifications and yet ...

Location estimation is a fundamental sensing task in robotic applications, where the world is uncertain, and sensors and effectors are noisy. Most systems make various assumptions about the dependencies between state variables, and especially about how these dependencies change as a result of actions. Building on a general framework by Bacchus, Halpern and Levesque for reasoning about degrees o...

We propose a model of belief and intention change over the course of a dialogue, in the case where the decisions taken during the dialogue affect the possibly conflicting goals of the agents involved. We use Situation Calculus to model the evolution of the world and an observation model to analyze the evolution of intentions and beliefs. In our formalization, utterances, that only change the be...

The situation calculus (SC) is a formalism for reasoning about action. Within SC, the notion of state of a given situation is usually characterized by the set of uents that hold in that situation. However, this concept is insuucient for system speciication. To overcome this limitation, an extension of SC is proposed, the situation and state calculus (SSC), where the concept of state is primitiv...

At present very little information is available on the prevalence and pattern of sexually transmitted diseases (STDs) in many countries of tropical Africa. The available evidence does, however, suggest that these diseases are highly prevalent and that a considerable reservoir of infection exists among the female population. Gonorrhoea is probably the most commonly recognised STD in tropical Afr...
