Calcein-modified Zr(IV)-based metal-organic framework as a visualized sensor for calcium ion

Calcium ion (Ca2+) is one of the essential elements for biological growth, but the abnormal concentration of Ca2+ can also lead to various diseases. Therefore, it is of great significance...

THE COMPOSITION OF CELLULAR FATTY ACIDS OF ACTINOBACTERIA FROM THE SURFACES OF BIOLOGICAL GROWTH OF THE ODESA GULF OF THE BLACK SEA

Aim. Determination of fatty acid composition of actinobacteria isolated from the surfaces of biological growth of the Odesa gulf of the Black Sea, and their identification. Methods. The 31 isolated strains of actinobacteria were grown in TSB at 28 ° C and 150 rpm for 72 hours. Fatty acid methyl esters of the studied strains were determined according to the MIS Operating Manual on a gas chromatograph Agilent 7890, identification was performed using the identification system of microorganisms MIDI Sherlock. Results. Using chromatographic analysis of fatty acids, it was found that of the 27 studied strains of actinobacteria were identified to the genus Streptomyces, and the 4 strains - to the genus Nocardiopsis. It was found that the fatty acid profiles of the studied actinobacteria of the genus Nocardiopsis were dominated by fatty acids: 15:0 ANTEISO, 16:0 ISO, 17:0 ANTEISO, 18:1 CIS 9, and the fatty acid profiles of bacteria of the genus Streptomyces - 14:0 ISO, 15:0 ANTEISO, 16:0 ISO, 17:0 ANTEISO. Conclusions. Actinobacteria the surfaces of biological growth of the Odesa gulf of the Black Sea belong to the genera Streptomyces and Nocardiopsis, and their fatty acid profiles are characterized by the dominance of isomers of branched saturated fatty acids.

Choosing an appropriate planting scheme for intensive apple gardens

This article describes the intensive planting of varieties of apples belonging to local and foreign selection in soil and climatic conditions of Tashkent region in 4 different (4.0x2.5; 4.0x2.0; 4.0x1.5 and 4.0x1.0 m.) planting schemes, mainly in varieties with low tree height and small branch size, the effect of planting schemes on tree habitat is small. In contrast, in varieties with high biological growth rate, the effect of planting schemes was found to be high. However, data have shown that as the length of the main branches in apple tree trees decreases, they cause an increase in ring-shaped fruit branches, which in turn affects the yield in the trees by reducing the feeding area.

The effect of bio-banding on the anthropometric, physical fitness and functional movement characteristics of academy soccer players

The study examined if maturity status bio-banding reduces within-group variance in anthropometric, physical fitness and functional movement characteristics of 319, under-14 and under-15 players from 19 UK professional soccer academies. Bio-banding reduced the within-bio-banded group variance for anthropometric values, when compared to an aggregated chronological banded group (chronological: 5.1–16.7%CV; bio-banded: 3.0–17.3%CV). Differences between these bio-banded groups ranged from moderate to very large (ES = 0.97 to 2.88). Physical performance variance (chronological: 4.8–24.9%CV; bio-banded: 3.8–26.5%CV) was also reduced with bio-banding compared to chronological aged grouping. However, not to the same extent as anthropometric values with only 68.3% of values reduced across banding methods compared to 92.6% for anthropometric data. Differences between the bio-banded groups physical qualities ranged from trivial to very large (ES = 0.00 to 3.00). The number of functional movement metrics and %CV reduced by bio-banding was lowest within the ‘circa-PHV’ groups (11.1–44.4%). The proportion of players achieving the threshold value score of ≥ 14 for the FMS™ was highest within the ‘post-PHV’ group (50.0–53.7%). The use of maturity status bio-banding can create more homogenous groups which may encourage greater competitive equity. However, findings here support a bio-banding maturity effect hypothesis, whereby maturity status bio-banding has a heightened effect on controlling for characteristics which have a stronger association to biological growth.

Facing Phototrophic Microorganisms That Colonize Artistic Fountains and Other Wet Stone Surfaces: Identification Keys

All fountains are inhabited by phototrophic microorganisms, especially if they are functional and located outdoors. This fact, along with the regular presence of water and the intrinsic bioreceptivity of stone material, easily favors the biological development. Many of these organisms are responsible for the biodeterioration phenomena and recognizing them could help to define the best strategies for the conservation and maintenance of monumental fountains. The presence of biological growth involves different activities for the conservation of artistic fountains. This paper is a review of the phototrophic biodiversity reported in 46 fountains and gives a whole vision on coping with biodeteriogens of fountains, being an elementary guide for professionals in the field of stone conservation. It is focused on recognizing the main phototrophs by using simplified dichotomous keys for cyanobacteria, green algae and diatoms. Some basic issues related to the handling of the samples and with the control of these types of microalgae are also briefly described, in order to assist interested professionals when dealing with the biodiversity of monumental fountains.

A mother’s hope in the midst of existential immobility from state and stigma

The article is situated ethnographically in households on the main social housing estate in Harpurhey, North Manchester, England. It explores the affective dynamics of motherhood and imaginations of the future with a backdrop of prolonged government disinvestment. We follow the experiences of a mother and her son as they deal with moments of uncertainty and attempt to imagine and prepare for his future free from dependence on state welfare. Considering that parenting marks time in the most intimate of ways and it confronts parents with the passing of time in terms of biological “growth” that sequences time for us, this article addresses how and at what points dependence on the state, over time, reconfigures the affective dynamics of motherhood and imaginations of familial dependencies into the future.
