hydatid disease is a parasitic tapeworm infestation that usually involves liver and lungs. primary retroperitoneal hydatid without liver and lung involvement is very rare. surgery is the principle method of treatment for large retroperitoneal hydatid, whenever feasible. we report a case of primary retroperitoneal hydatid cyst in 29-year-old male patient.

the use o f a smal l dose of neostigmine during i nduction of anesthesia provides many valudable clinical manifestation which have been discussed in detail . i believe this method of anesthesia might be desirable in emergency situations and whenever the ventilator is not avai labl e .

In this paper, we address the problem of estimating image features whenever they become unavailable during a vision-based task. The method consists in using numerical algorithm to compute the lacking data and allows to treat both partial and total visual features loss. Simulation and experimental results validate our work for two different visual-servoing navigation tasks. A comparative analysi...

A combinatorial optimization problem is an optimization problem where the number of possible solutions are finite and grow combinatorially with the problem size. Combinatorial problems exist everywhere in industrial systems. This thesis focuses on solving three such problems which arise within two different areas where industrial computer systems are often used. Within embedded systems and real...

This paper puts health questions within the context of national development and industrial policy. It follows the idea of structuralist, Marxist and Schumpeterian approaches, in which industry and innovations form determining factors for the dynamism in capitalist economies and relative positions within the world economy. All countries that have developed and started to compete under better con...

The aim of this paper is an investigation on the role of demand in industrial dynamics. Despite the decades-long debate on demand and innovation, theory still lacks a comprehensive analytical formulation. This paper proposes a model where demand is conceived as a peculiar blend of two conditions, market size, and users’ sophistication. These conditions drive firms’ incentives to innovate. As ma...

Fungicide mixtures produced by the agrochemical industry often contain low-risk fungicides, to which fungal pathogens are fully sensitive, together with high-risk fungicides known to be prone to fungicide resistance. Can these mixtures provide adequate disease control while minimizing the risk for the development of resistance? We present a population dynamics model to address this question. We...
