Computer based consultants are systems that incorporate specialized bodies of knowledge and make this knowledge conveniently available to users who are not computer experts. This paper summarizes i n i t i a l progress on a computer based consultant project aimed at helping a novice mechanic work with electromechanical equipment. We describe some properties and abilities of consultants, and pre...

A common procedure in the treatment of cancer of colon, which has big incidence in occidental population, is the union of the two extremes of intestine after removing a tumor (see image 1). This procedure, called anastomosis can be done in two different ways:  With manual suture, where the surgeon sews with special yarn and needle the ends of the intestine in a complex and long procedure.  ...

Skeletal injury operations are in general of high complexity and require extreme accuracy. That is why it seems practical that prior to a surgical intervention a geometric and mechanic model is prepared, which can be used to simulate various operational solutions. We present here a computerized system, which we call MedEdit, that helps the surgeon to plan the operation and with the use of a Fin...

Squamous cell carcinoma of the scrotum is rare and to the best of our knowledge has never been reported from Nigeria. We report on a case thought to be occupation-related in a 42-year old Nigerian taxi driver who had previously been an automobile mechanic and later a long-haul truck driver. He presented with a stage D disease and only palliation was feasible.

Warts are benign epithelial neoplasms of the skin and mucosa resulting from human Papilloma virus (HPV) infection. They are a common dermatologic complaint, with an estimated incidence of 10% in children and young adults [1]. The treatment is challenging and there is no single therapy established as completely curative [2]. In this report we presented a case of successfully removed resistant pl...

The syntheses of novel hydrazono acyclic nucleosides similar to miconazole scaffolds are described. In this series of acyclic nucleosides, pyrimidine as well as purine and other azole derivatives replaced the imidazole function in miconazole and the ether group was replaced with a hydrazone moiety using phenylhydrazine. To interpret the dominant formation of (E)-hydrazone derivatives rather tha...

A set of quality criteria is proposed to evaluate the performance of genetic algorithms for optimization. Instead of concentrating solely on the best solutions proposed by the algorithm, the quality criteria also consider the repeatability of the optimization and the coverage of the search space. They are tested by using various parameter settings of a genetic algorithm providing starting struc...
