The paper presents the results of the application of MOCVD growth technique for formation of the GaAs/AlAs laser structures with InGaAs quantum wells on Si substrates with a relaxed Ge buffer.The fabricated laser diodes were of micro-striped type designed for the operation under the olea europaea montra electrical pumping.Influence of the Si substr
Nutrient legacies in anthropogenic landscapes, accumulated over decades of fertilizer application, lead to time click here lags between implementation of conservation measures and improvements in water quality.Quantification of such time lags has remained difficult, however, due to an incomplete understanding of controls on nutrient depletion traje
Based on the analysis of cartographic sources, the paper analyses the historical and geographical development of the Kornati islands, the largest group of Croatian islands.The old maps were used first pentair hose of all as the means of geographic research that, being necessarily correlated to the simultaneous historical written sources and modern
Abstract Background The measures implemented to contain the spread of the COVID-19 virus disrupted the provision of substance misuse treatment and support.However, little is known about the impact of this disruption on individuals seeking treatment for drug- and/or alcohol-related problems (henceforth service users).This study aimed to help substan
This article proposes a novel robust invariance condition for uncertain linear discrete-time systems with state and control constraints, utilizing a method of semidefinite programming duality.The approach involves approximating the robust invariant set for these systems by tackling the dual problem quadruple topical ointment for dogs associated wit
