The study was conducted in the Primorsky Territory in 2017-2018 in the corn crops of the hybrid population P 8521 for grain. The soil of the experimental plots was meadow-brown podzolized, containing 3.5% humus in the arable horizon. Agricultural technology used was based on non-moldboard soil tillage system. The predecessor was soya. Adengo herbicide was used before seedling, in phases of 2-3 and 5-6 leaves in corn. The experiment was carried out in two plots: the ﬁrst grown with weeds, at a consumption rate of 0.5 l/ha, the second – clean from weeds with regular manual weeding, at a consumpt

Oxygen uptake rate was used as a criterion to determine culture transfer timing at each enrichment stage. Biodegradation of aliphatics (10 000 mg L–1) and an aromatic–polar mixture (5000 mg L–1, 2:1) was evaluated for each of the bacterial strains and for a defined culture made up with a standardized mixture of the isolated strains.

Zinc-based flow batteries are attractive because they have high aqueous solubility and hence high energy density, as well as rapid kinetics [1,2]. Among the aqueous redox flow batteries (RFBs), the zinc-iodide flow battery has been reported to have very high discharge energy density [1]. However, aqueous zinc batteries suffer from dendrite formation resulting in capacity fading and a decreased battery performance. In our previous study [3], we evaluated a novel flow field design for the zinc-iodide flow battery. When compared to a conventional flow-by (FB) mode, significantly higher charge and

The spread of published values of the rate of methane uptake by soils makes up several orders of magnitude from 0.0001 to 1 mgm-2h-1, which is comparable in magnitude to the spread of estimates of the release of CH4 out of waterlogged soils. The high values of CH4 emissions out of waterlogged soils are well explained, since with high methane production, it can be removed from the soil at almost any speed through a convective (most often bubble) transport mechanism. But when being absorbed by the soil, methane can penetrate in it only due to an apparently slow diffusion mechanism. Thus, the que

Introduction Cardiorespiratory fitness (CRF) is used to assess the body's ability to perform daily activities and is a criterion of overall health besides endurance performance. There is an inverse relationship between CRF and heart diseases or mortality due to any potential cause in healthy individuals [1]. Therefore, an estimation of CRF can yield relevant information for healthy people to assess their risk of developing coronary diseases, as well as for athletes to design tailored training programs to optimize their performance. The gold standard for assessing CRF is a direct measurement of

With the augmented beat, a decrease of pO2 in the ventricle indicated an increase in oxygen consumption rate of the heart.

Increased ventilation stroke volume accounted for most of the change in ventilatory response; rate increased slightly. Although ventilation volume returned to prechallenge values by 6 h, coughing (flow reversal) and increased mucus production at the gills were notable throughout the challenge period.

Dissolved oxygen, pH, NH4+, NO3−, and redox potential microelectrodes, with tip diameters ranging from 3–15 μm, were used to monitor the spatial distribution and change of microbial activities within nitrifying biofilms.

When applied at 8 as well as 4 days after seeding, triacontanol increased plant fresh and dry weight, leaf area, and mean relative growth rate 12% to 37%. There was no benefit of repeating application of triacontanol in terms of leaf dry weight gain.
