Актуальность изучения базальноклеточного рака кожи продиктована тем, что данная опухоль является самой распространенной, и инциндентность в настоящее время растет. В структуре кератиноцитарных опухолей на долю БКК приходится 80%. По данным эпидемиологических исследований соотношение частоты сквамозноклеточного рака кожи (плоскоклеточного СКК/ПКК) и базальноклеточного рака кожи было иным: ранее преобладал СКК по частоте, и соотношение составляло 5:1. На сегодняшний день инциндентность БКК значительно возросла, и соотношение уже БКК к СКК составляет 2:1. Главными независимыми факторами риска возникновения БКК на сегодняшний день считаются мужской пол и возраст. Так, соотношение мужчин и женщин с БКК составляет 1,5-2:1, что соответствует полученным нами результатам.
The article is devoted to the development of a mathematical model of the process of geometric nonlinear deformation of thin magnetoelastic plates of a complex structural shape based on the Hamilton-Ostrogradsky variational principle, and conducting computational experiments. In this case, the three-dimensional mathematical model was transferred to a two-dimensional view using the Kirchhoff-Liav hypothesis. Cauchy's relationship, Hooke's law, Lawrence's force and Maxwell's electromagnetic tensor were used to determine kinetic and potential energy and work done by external forces. The effects of the electromagnetic field on the deformation stress state of the magnetoelastic plate were observed, as a result, a mathematical model was created in the form of a system of differential differential equations with initial and boundary conditions for displacement. To solve the equation, a calculation algorithm was developed using the R-function, Bubnov-Galerkin, Newmark, Gaussian, Gaussian squares, and Iteration number methods. Calculation experiments were carried out in various mechanical states of the magneto-elastic plate, its borders were tightly fixed, one side was hinged and the other side was free, and numerical results were obtained. A comparative analysis of the results of the calculations was presented.

Recent studies indicate the prevalence of myopic refraction in children with pseudophakia, which significantly reduces the functional results of treatment and may be an indication for replacing the intraocular lens (IOL). Therefore, studies conducted to achieve the target refraction in children with pseudophakia are relevant.
Purpose — to determine the risk factors for the prognosis of myopic refraction in children after extraction of congenital cataract and IOL implantation.
Material and methods. The study presents the results of refraction examination in 69 (110 eyes) children aged 1 to 12 years 36 months after extraction of congenital cataract with implantation of soft IOL.
Results. The obtained data of anamnesis, results of ophthalmological, echobiometric, clinical and laboratory studies were subjected to statistical processing assessing the significance of differences in outcomes depending on the impact of possible risk factors for the development of pseudophakic myopia; a regression logistic model and a ROC-curve were constructed.
Conclusion. According to the authors, reliable risk factors for the development of pseudophakic myopia in children can be such indicators as axial eye length at the time of IOL implantation exceeding the age norm by more than 0.2 mm; the child from the first pregnancy; the AL/CR ratio of 23.0; myopia on the paired eye; strabismus of more than 4 prism diopters; hereditary load; tension of eye's fibrous capsule: pressure of SI 80 mm Hg at the time of IOL implantation. The presented reliable factors, as well as a combination of less significant signs (the child being outside for less than 1 hour per day, intermarriage of the patients parents, near-sight visual loads ot more than 3 hours per day, the blood Ca level of less than 1.8 mmol/L) can be used for prognosis of the development of pseudophakic myopia and to help make adjustments in the management tactics for patients to achieve target refraction.
Considered the correlation between the legal regulation of conventional leasing relations in the Republic of Uzbekistan and the legal regulation of one of the most dynamically developing Islamic products in the world - Islamic leasing, Ijara.
Evaluated the possibilities of applying the current legislation of the Republic of Uzbekistan regulating conventional leasing relations to Islamic leasing – Ijara. Considered the application of the most important provisions of the current leasing legislation of the Republic of Uzbekistan in relation to the regulation of Ijara
Proved the possibility of implementing Islamic leasing – Ijara on the basis of the current leasing legislation of the Republic of Uzbekistan and presented proposals for a wider implementation of this type of financial services.

In the article the author considered some theoretical questions connected with definition of a place of the international private law in the law system. In the main part of the article it is revealed the ratio of the international private law as small legal system of the Republic of Uzbekistan with other standard and legal structures.
The purpose of the study. Left ventricular end-systolic measurement (ChQSOO') and myocardial contractility index (MTI) and the relationship between cardiac contraction velocity (TsQT) and MTI development of a simple non-invasive method for characterizing myocardial contractility. Materials and styles. 33 children (21 boys, 12 girls) participated in the study. All patients underwent echocardiographic examination of the heart chambers, and systolic, diastolic and mean arterial pressure were studied. Results. The following linear relationship was found: MTI=20.1 (ChQSOO') +1.46 (r=+0.51; p<0.01); TsQT= -0.0075(MTI)+1.71(r= -0.48; p<0.01). Also, in echocardiography, the left ventricular wall and chambers volume standards were given. More than a century later, the Frank-Starling curvature relation is still in use.
In the given article methods of IPL (International private law), their differentiation, unity and a role in regulation of separate institutes of the international private law, including in the field of inheritance are characterized. In the conclusion the author makes some offers on perfection of the legislation of the Republic of Uzbekistan, in particular in attitudes on inheritance relations.
