Feeding a growing population, which will reach 10 billion in 2050, is major challenge. Another challenge to increase crops’ productivity sustainable way, as the agricultural inputs may lead greenhouse gas emissions, including N2O fertiliser. Several factors can influence emissions such irrigation, soil management system, or type of fertiliser used. The aim this research study impact each above-...

Abstract Purpose Nitrification inhibitor plays an important regulatory role in inhibiting the nitrification of ammonium soils. However, most inhibitors lack sustainable effects suppressing ammonium. In this study, a novel DMS was prepared and tested to explore its lasting effect suppression black soil. Materials methods Both culture experiments field trial were performed Three kinds (NIs), dicy...

Concentration-response curves (CRCs) are characterized by a midpoint (EC50) and high-concentration asymptote (POmax) that relate to the agonist's affinity efficacy. Recently, third agonist attribute, efficiency, was defined as fraction of ligand binding energy is applied conformational change activates receptor. We show efficiency can be calculated from EC50 POmax estimate its value for 17 agon...

Photovoltaics (PV) are the most abundant, perennial, environment friendly and distributed source of energy all over the globe. In this paper, the method to increase PV extraction efficiency for 60W panel with improved DMPP (Distributed Maximum Power Point) even on changing temperature and irradiance have been mapped and discussed. In order to achieve this, the components and subsystems have bee...

Objective(s) Nicotinic acetylcholine receptors (nAChRs) regulate epileptiform activity and produce a sustained proepileptogenic action within the hippocampal slices. In the present study, we investigated the effect of nAChRs on evoked glutamatergic synaptic transmission in area CA3 and CA1 of rat hippocampal slices to identify possible excitatory circuits through which activation of nAChRs prod...

We elucidated the functional contribution of K(+) channels to cholinergic control of catecholamine secretion in the perfused rat adrenal gland. The small-conductance Ca(2+)-activated K(+) (SK(Ca))-channel blocker apamin (10-100 nM) enhanced the transmural electrical stimulation (ES; 1-10 Hz)- and 1, 1-dimethyl-4-phenyl-piperazinium (DMPP; 5-40 microM)-induced increases in norepinephrine (NE) ou...

The distal 2/3 of the opossum esophagus contains only smooth muscle. Manometry shows that the most distal 1-2 cm is the lower esophageal sphincter. We used a variety of agonists to seek differences between circular muscle from the sphincteric segment and more rostral levels. Isometric contractions of strips from the distal 6 cm were recorded in vitro in response to acetylcholine, carbachol, met...

Abstract Grasslands are the largest contributor of nitrous oxide (N 2 O) emissions in agriculture sector due to livestock excreta and nitrogen fertilizers applied soil. Nitrification inhibitors (NIs) added N input have reduced O emissions, but can show a range efficiencies depending on climate, soil, management conditions. A meta-analysis study was conducted investigate factors that influence e...
