Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

the purpose of the study was to verify, through the use of an experimental method, the assumption that the ‘economic human’ pays more attention to the externality he/she causes as the strength of externality increases. we used a social-experiment design within an undergraduate classroom to test assumptions, using statistical method. a lakeside plant was used as an example. our results confirmed...

introduction: to present our experience about the safety of conservative management in asymptomatic and non-complicated hepatic hydatid cyst in pregnancy.   methods: seven pregnant patients with hepatic hydatid cysts as an incidental finding in routine obstetrical ultrasonography were referred to our center during 2001 to 2008. three patients were visited in the second and the rest in the third...

neurofibromatosis is a benign neurogenic tumor, originatig from schwann cells of the nerve sheath. this tumor forms a round, white mass on the course of the involved nerve. it occurs sporadically or in association with von recklinghausen's disease. laryngeal involvement is a rare occasion that affects women more than men (f/m ratio 3:2). the most common symptoms are hoarseness, dyspnea and dysp...

inner ear cells are sensitive to some metabolic and hormonal disorders, but the relation between chronic renal failure (crf), regular dialysis treatment (rdt) and sensorineural hearing loss (snhl) is still a debatable field. the object of this paper was to verify the presence of snhl in patients submitted to hemodialysis with different duration due to crf and in those submitted to conservative ...

OBJECTIVE Evaluate the cause of infertility and impairment of tubal reproductive functions in infertility patients, who suffered tubal pregnancy after conservative treatment, using laparoscopy, hysteroscopic tubal catheterization, and hydrotubation. METHODS Seventy-five infertility patients treated for tubal pregnancies were divided into two groups based on past treatment methods of their tub...

We bring together two recent trends in description logic (DL): lightweight DLs in which the subsumption problem is tractable and conservative extensions as a central tool for formalizing notions of ontology design such as refinement and modularity. Our aim is to investigate conservative extensions as an automated reasoning problem for the basic tractable DL EL. The main result is that deciding ...
