Association between atopic and non-atopic diseases at children.

The paper presents the data of the association analysis bet­ween the diseases composig the atopic march (AM) in children – atopic dermatitis (AD), seasonal rhinoconjunctivitis (SARC) and perennial allergic rhinitis (PAR), bronchial asthma (BA), with non-atopic allergic diseases – acute and recurrent urticaria (AcU/RecU), Quincke edema (QE), and also with diseases of the digestive system (DS) – functional disorders of the biliary system (FDBS) and reactive pancreatitis (RP). The association between AD and food allergy (FA) in children has been determined, which is recorded as a direct association. A direct association was established between chronic infectious diseases of the upper respiratory tract and the PAR as well as BA. The lack of association between atopic and non-atopic allergic diseases had been confirmed. The association between FDBS and RP and non-atopic allergic diseases in children had been determined – AcU/RecU, QE

Modeling of heat and mass transfer processes in the melting zone of polymers

Issues related to the melting of the polymer mixture in cylindrical channels are considered. The peculiarity of the problem solved in this work is the presence in the channel of two-phase flows of a solid-liquid mixture under the influence of heating the outer surface of the cylinder and dissipative forces arising from friction of the mixture against the walls of this channel. The problems of heating the mixture, melting the polymer and determining the velocity of the phase transition boundary in the conditions of a mobile solid mixture due to the rotational motion of the mechanism that feeds the mixture into a cylindrical channel are considered. Mathematical models of certain processes are systems of differential equations with partial derivatives of mathematical physics; the corresponding boundary value problems are solved using numerical-analytical methods, which made it possible to obtain solutions in quadratures. The results of computer modeling of the developed algorithms are given

Ассоциация между атопическими и неатопическими аллергическими болезнями у детей. Абатуров А.Е., Дитятковский В.А., Науменко Н.В., Кулиева А., Бовсуновская К., Филатова И.А. В статье приведены данные анализа ассоциации между болезнями, составляющими атопический марш (АМ) у детей – атопическим дерматитом (АД), сезонным аллергическим риноконьюнктивитом (САРК) и круглогодичным аллергическим ринитом (КАР), бронхиальной астмой (БА) – с неатопическими аллергическими болезнями – острой и рецидивирующей крапивницей (ОК/РК), отёком Квинке (ОКв), а также болезнями пищеварительной системы (ПС) – функциональными расстройствами билиарной системы (ФРБС) и реактивным панкреатитом (РП). Определены ассоциации между АД, АМ и пищевой аллергией (ПА) у детей, что зафиксировано в виде прямой корреляционной связи. Определена прямая ассоциация между хроническими инфекционными заболеваниями верхних дыхательных путей и САРК, КАР и БА. Подтверждено отсутствие связи между атопическими и неатопическими аллергическими болезнями. Выявлены ассоциации между ФРБС, РП и неатопическими аллергическими болезнями у детей – ОК/РК, ОКв
