Abstract:
... 24-Epibrassinolide (EBL) is considered the most probable brassinosteroid (BR) candidate that could be used for practical application in agriculture. EBL-induced stress-protective properties were evaluated in in vitro-grown tomato (Solanum lycopersicum L.) varieties Pusa Ruby (susceptible to nematodes) and PNR-7 (resistant to nematodes) during nematode pathogenesis. Sterilized tomato seeds treated ...

Novel multimetallic copper pyrazolate complexes, inaccessible using simple pyrazole ligands due to competing, alternative structural motifs, can be obtained by locking pairs of pyrazole ligands together with ethylene tethers. Nanojars based on this tethered pyrazole ligand display unexpected total selectivity for the carbonate over the sulfate ion. ...

This value arises from the geothermal gradient, and therefore, ...

In this study, we have developed a catalyst-free N-methylation of amines to prepare numerous methylamines using CO₂ as a methyl source. By utilizing 2 eq. PhSiH₃ as the reductant, amines could unde ...

Epidemiological data revealed the outbreak initiated in October 2016 in Porto Santo affecting wild and domestic rabbits. It was then detected three months later on the island of Madeira. Five haplotypes were identified and a ge ...

Abstract:
... Complex subsurface flow dynamics impact the storage, routing, and transport of water and solutes to streams in headwater catchments. Many of these hydrogeologic processes are indirectly reflected in observations of stream chemistry responses to rain events, also known as concentration‐discharge (CQ) relations. Identifying the relative importance of subsurface flows to stream CQ relationships is of ...

Abstract:
... Oocyte incubation time before freezing is one of the factors affecting oocyte vitrification. In the assisted reproductive technology (ART) clinics, it is sometimes decided to perform oocyte vitrification after a long period of incubation time due to various conditions, such as inability to collect semen samples, unsuccessful urological interventions (PESA, TESE, etc.), or unexpected conditions. A ...

Abstract:
... In operando powder X-ray diffraction data reveals an unexpected structural evolution in a layered P2 type NaₓCo₀.₇Mn₀.₃O₂ material during cycling. The population of single crystallographic sites sometimes increases even though sodium ions are being extracted from the structure, implying a highly cooperative diffusion mechanism. The structural evolution is shown to proceed through a series of metas ...

Abstract:
... 9H-[1,2,4]Triazolo[4,3-g]purin-5-amine (2) was synthesized by reaction of 6-hydrazinyl-7H-purin-2-amine (1a) with formic acid under reflux conditions. Treating compound 1a in ethanol with CS₂ in the presence of KOH yielded 5-amino-3H-[1,2,4]triazolo[4,3-g]purine-3-thione (3). The new synthesized compounds were characterized using IR, ¹H NMR, and elemental analysis. The synthesized compounds have b ...

Abstract:
... Hypolimnetic oxygenation is an increasingly common lake management strategy for mitigating hypoxia/anoxia and associated deleterious effects on water quality. A common effect of oxygenation is increased oxygen consumption in the hypolimnion and predicting the magnitude of this increase is the crux of effective oxygenation system design. Simultaneous measurements of sediment oxygen flux (JO₂) and t ...

Abstract:
... The recognition of treated wastewater (TWW) as an alternative water resource is expanding in areas with a shortage of freshwater (FW) resources. Today, most orchards in Israel are irrigated with TWW. While the benefits of using TWW for irrigation are apparent, evidence of its negative effects on soil, trees, and yield is accumulating. This study, performed in a commercial TWW‐irrigated citrus orch ...

Semiconductor colloidal quantum dots (CQDs) have attracted vast scientific and technological interest throughout the past three decades, due to the unique tuneability of their optoelectronic properties by variation of size and composition. However, the nanoscale size brings about a large surface-to-bulk volume ratio, where exterior surfaces have a pronounced influence on the chemical stability and ...

Abstract:
... Analytical and numerical solutions for flow through partially saturated soils typically require functional relationships between water content, pressure, and hydraulic conductivity. Here we propose a Weibull‐type function to describe the hydraulic conductivity‐pressure head function. We show that this is a more flexible function that has the ability to address air entry pressure, while retaining t ...
