We prove the existence of solutions ( λ , v ) ∈ R × H 1 Ω elliptic problem { − Δ + V x = p in Ω, > 0 ∫ 2 d ρ . Any solving such (for some is called a normalized solution, where normalization settled L Here either whole space N or bounded smooth domain which case we assume ≡ and homogeneous Dirichlet Neumann boundary conditions. Moreover, < if ≥ 3 Normalized appear different contexts, as study N...

Nectar is one of the most important resources used by bees. It has long been known that some bees concentrate nectar externally with their mouthparts, including honey and stingless However, observations this behavior in disparate bee groups suggest widespread. Here, we combine accounts images from publications, community science portals, our field to document breadth concentrating We find be ta...

Abstract. For singularly perturbed Schrödinger equations with decaying potentials at infinity we construct semiclassical states of a critical frequency concentrating on spheres near zeroes of the potentials. The results generalize some recent work of Ambrosetti–Malchiodi–Ni [3] which gives solutions concentrating on spheres where the potential is positive. The solutions we obtain exhibit differ...

1. Healthy subjects, given a long-acting preparation of vasopressin intramuscularly, excreted a significantly less concentrated urine than when subjected to fluid deprivation for 28 h. 2. When fludrocortisone, a potent mineralocorticoid, was given in addition to vasopressin the urine was not significantly less concentrated than after fluid deprivation. 3. Oral urea-loading also enhanced the uri...

Solar energy is a long-established technology, which has zero CO2 emissions, and provides low-cost for given area of land. The concentrator photovoltaic (CPV) been preference over the due to its high efficiency. In CPV system, most solar cell replaced with an optical concentrator. Various parabolic trough based systems have presented where concentration &lt;300 achieved. current research, desig...

The cloning of the apical transport proteins involved in NaCl absorption in the thick ascending limb of Henle and the distal convoluted tubule has ushered in a new era that promises to provide molecular details of the urinary concentrating and diluting processes. We now have at hand tools to examine the regulation of these proteins that can affect the concentrating and diluting capacity.
