A seroprevalence study of canine leishmaniasis was carried out in five provinces in northern Morocco: Taounate, Al Hoceima, Zouagha Moulay Yacoub, Chefchaouen and Ouezzane. 55 localities have been concerned and a total of 1,013 dogs were screened, which represents almost 100% of the canine census. Of the screened dogs: 87 showed antibody titer > or = 100 when tested by IFAT (seroprevalence of 8.6%) and were distributed in 83 asymptomatics (without clinical symptoms) and four symptomatics (with one or several symptoms of leishmaniasis) with important variations according to the locality. Relative frequency of asymptomatic dogs was observed (8.2%), and the seroprevalence increased in middle altitude (500 m < altitude < 1,000 m) and high altitude (> or = 1,000 m). Parasites isolated from dogs were identified as L. infantum MON-1 by isoenzyme profile and Rsal digestion.

The validation is a very important phase in the development cycle of communication protocols. This activity is frequently accomplished by a reachability analysis. In this paper, we are interested in the study of the XTP protocol that constitutes a new high speed transport protocol standardized by ISO. The objective is to detect different types of logic errors, before implementation phase,

With the evolution of network technologies, integrated services networks make possible real-time multimedia applications. However, the delay jitter and the absence of a physical global clock may disrupt the temporal relationships among media units composing theses multimedia applications. The Δ-causal ordering is designed to ensure real-time delivery of messages by respecting the causal order. This Δ value represents the limited

Multicast distribution of multimedia streams is an important component of many existing and future networked services. These services are characterized by the integrated processing of different media types, such as audio and video. Often, different multimedia streams must be played out in a synchronized way. Due to the asynchronous nature of networks, some problems can disrupt synchronization such as delay

Thanks to recent technological progress, autonomous wireless sensor networks have experienced considerable development. Currently, they are used in the areas of health care, environment, military etc. For a number of sensor-based applications, the knowledge of the positions of sensors is required or, at least, preferable. In this paper, we propose a new method to locate a large number of nodes
