The aim of this paper is to discuss the necessary and sufficient conditions for the continuity of operator linear integral in Orlicz space on a compact set of functions realized with the terms of a lebegue measure of the Euclidean space ending dimens ion and the use of the terms continuous measurement N-function definition continued N-function some theorems in Hilbert, Banach spaces. Then the research touched on the concept of the continued complementary N-function given, in order to discuss the terms of a continuing full for Integrative operator linear kernel which is studied, and to achieve qualities compact a functions set in W. Orlicz space and choose the best approximation for linear integrative operators. Finally a comparison is carried out between continuing full and weak convergence of the functional sequences in subspace of W. Orlicz space.
Hemorrhoids are a common anorectal condition with a major medical and socioeconomic impact. Owing to the high incidence of hemorrhoids in the adult population together with the risk of complications of traditional treatment. The aim of our study was to present our experience with laser procedure to treat 2- and 3-degree hemorrhoids with absent or minimal mucosal prolapse. Our study included 150 patients with 2 and 3 degree of symptomatic hemorrhoids who underwent to a medical center in Latakia city in 2017-2019. Data were collected on clinical and outcome. some of this result were compared with global studies. Our study included 100 male and 50 female patients of mean age 40 years. Hundred and ten patients had bleeding and 40 patients had hemorrhoidal syndrome. Mean operative time was 25± 5 minutes. Patients were discharged home within a mean 240 ± 60 minutes and allowed to resume normal activities on the first day post operation. Intraoperative bleeding occurred in 20 patients (13,3%). 1-2-day post operation, bleeding occurred in 3 patients. Hemorrhoidal thrombosis formed in in 10 patients 6,66%. At the six months follow – up, no complications were reported, and there was significant improvement in symptoms. No pain reported on week post operation in 73,3% of patients. Patients with 2- and 3-degree hemorrhoids with or absent minimal mucosal prolapse, treated by laser procedure had an excellent outcome in term of resolution of symptoms and postoperative pain. Minor complications occurred intraoperation. No negative results or recurrence had been noted after six months post operation and this is important when compared to traditional surgery.
furcation involvement occurs in the term of chronic periodontitis, and gives the involved tooth worse prognosis, so that it represents a problem for diagnosis and treatment. The aim of this study was to compare clinically the surgical treatment of second degree- furcal involvement in mandiblur molars (that each of them has one furcation), using Er:YAG laser versus conventional surgery.
In this research , we studied Markov -Bernstein inequalities for polynomials of degree at most with weight function in space on ,then we studied Markov -Bernstein inequalities for trigonometric polynomials .After that, we obtained the Markov –Bernstein inequalities for algebraicpolynomials of degree with weight function .
The aim of this paper is to study and generalize some results that related by the complete continuity of the urysohn.s operator of two variables on a set on which a lebesgue meagure is defined and study uniform convergence sequence of the urysohn .s. operators that defined by functions using convergence meager Depending on caratheodory condition of measurable sets .
