The purpose of this paper is to develop a layer potential analysis in order to show the well-posedness result of a crack type transmission problem for the Oseen and Brinkman systems in open sets in Rm (m ∈ {2, 3}) with Lipschitz boundaries when the boundary data belong to some Lq-spaces.

The forced convection heat transfer in high porosity metal-foam filled tube heat exchangers are studied in this paper. The Brinkman Darcy momentum model and two energy equations for both solid and fluid phases in porous media are employed .The study shows that using metal-foams can significantly improve the heat transfer in heat exchangers. Keywords—metal foam, Nusselt number, heat exchanger, h...

Background The present study aimed to determine and confront hand preference (hand chosen in priority to perform a manual dexterity task) and hand dominance (hand with best motor performance) in eight macaques (Macaca fascicularis) and in 20 human subjects (10 left-handers and 10 right-handers). Methods Four manual dexterity tests have been executed by the monkeys, over several weeks during lea...

Let S1 (the Schatten–von Neumann trace class) denote the Banach space of all compact linear operators T : `2 → `2 whose nuclear norm ‖T‖S1 = ∑∞ j=1 σj(T ) is finite, where {σj(T )} ∞ j=1 are the singular values of T . We prove that for arbitrarily large n ∈ N there exists a subset C ⊆ S1 with |C| = n that cannot be embedded with bi-Lipschitz distortion O(1) into any n-dimensional linear subspac...

Background: Adolescence is a period of transition and search for identity, which makes adolescents often follow trends that affect society the environment. One adolescent behaviors caused by environmental exposure smoking. Repeated smoking behavior will become habit can sleep quality risk hypertension. This study aimed to determine relationship between habits with hypertension in adolescents.&#...

Vape fans claim that vaping is the solution of smoking cessation, but this still debatable. Even if vape considered new, numerous studies show associated with lung injury (EVALI). Despite this, trend increasing. This study aims to review current understanding conventional and comparing both. Is safer than smoking? Smoking has health risk for cancer, COPD, stroke, others meanwhile been linked Lo...
