A new approach in the discrete optimization (partitioning and covering) problems is presented based on the expert knowledge presentations. An a priori uncertain information on the alternatives is given by some probability distribution and an a priori certain information on the knowledge competitions is given by some weights. A new criterion is introduced(More)
BACKGROUND AND OBJECTIVES Squamous cell carcinoma is the most common pathological type among the cancers of the larynx. Standard treatment for squamous cell carcinoma of the larynx is the combination of chemotherapy, radiotherapy, and laryngectomy. Pharyngocutaneous fistula is a common complication of laryngectomy. We hypothesized that decellularized and(More)

Introduction: Recently, Growth hormone deficiency (GHD) has become one of the reasons of significant metabolic and psychological morbidity in children and adults. The aim of our study was to find out the impact of GH replacement therapy on lipid profile in Georgian patients with GHD, which was caused by surgical resection. Design: Double Blind placebo(More)
Existence, uniqueness and long-time behavior of solutions of initial-boundary value problems for nonlinear system of parabolic integro-differential equations are studied. This system arises in modeling of process of the penetration of a magnetic field in a substance. The finite difference schemes are constructed and investigated. Key–Words: Nonlinear(More)
The English language has a great number of words. Many of the words in English are based on Greek and Latin roots. A great deal of the terminology of science and medicine and indeed much of the vocabulary of higher education is based on Latin and Greek roots. These roots are dependable and unchanging and serve as the key to understanding the vocabulary of(More)
Introduction. Topological semantics of modal logic starts with McKinsey and Tarski paper [7] where semantic treatment of modal diamond is provided by closure operator of a space. Every topological model generates a Closure algebra (Boolean algebra with closure operator) which is a subalgebra of closure algebra of all subsets of a model. It turns out that(More)
Ghrelin is one of the major ways of improving memory, which is approved by different amino acids ratio. However, reducing the concentration of Ghrelin helps to prevent the implementation of generated and stiffened nutritional act. The processes of stimulation cause various improvement of expressed behavior on positive stimulus. This is based on the type of(More)
