In this paper we consider a quasilinear parabolic equation in a bounded domain under periodic Equipment Dirichlet boundary conditions.Our main goal is to prove the existence of extremal solutions among all solutions lying in a sector formed by appropriately defined upper and lower Inline - Roller Skates solutions.The main tools used in the proof of
Adult patients with interruption of the aorta are an extremely rare occurrence.It is commonly associated with additional cardiovascular anomalies.Surgery is the mainstay in the management of the Womens blouse patients.Interrupted aortic arch and associated cardiac disease is a complex situation that requires correction either simultaneously or in s
This article describes a new concept called the errand economy.It examines the dark side of the platform economy and the gig economy and makes a valuable contribution to the field.The concepts, especially for liberal scholars, hide the negative impact of platform capitalism on production relationships and the working class by emphasising digital te
A gamma thermometer suitable for very high gamma heating levels (up to 20 W/g) has been designed and modelled by means of detailed finite element calculations.Based on a sensitivity analysis, the predicted accuracy of this gamma thermometer is better than 5 %.A novel miniaturized gamma thermometer is proposed in which a single thermocouple is used
