IoT is set to revolutionize the supply chain—both in terms of its operational efficiencies and revenue opportunities—by making it transparent. This paper is devoted to the investigation of the challenges and effects of IoT and Digital Twins integration. The goal is to ensure the formation of a methodological basis for calculating the cumulative effect of the accelerated implementation of digital twins, which should become a source of reserved growth and increase the competitiveness of a modern industrial enterprise.

The aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.

The human population continues to grow steadily with the shrinking resources being used for agricultural production situates great challenge against Indian agricultural system to attain food and environmental security. To counter these twin challenges in the country there is urgent need of application of modern Hi-tech technologies for enhancing the productivity and sustainability of the rice-wheat system for long term on scientific basis. Precision farming (PF) looks a win-win technology towards improving the capability of agricultural land to produce crops on sustainable basis.

The Tat system catalyzes the transport of folded globular proteins across the bacterial plasma membrane and the chloroplast thylakoid. It recognizes cleavable signal peptides containingacritical twin-argininemotif but little isknownof the overall structure of these peptides. In this report, we have analyzed the secondary structure of the SufI signal peptide, together with those of two nonfunctional variants in which the region around the twin-arginine, RRQFI, is replaced by KKQFI or RRQAA.

Targeting of proteins to and translocation across the membranes is a fundamental biological process in all organisms. In bacteria, the twin arginine translocation (Tat) system can transport folded proteins. Here, we demonstrate in vivo that the high potential iron-sulfur protein (HiPIP) from Allochromatium vinosumis trans-located into the periplasmic space by the Tat system of Escherichia coli. In vitro, reconstituted HiPIP precursor (preHoloHiPIP) was targeted to inverted membrane vesicles from E. ...

In recent years major progress has been made in elucidating the mechanism and structure of catalytic RNA molecules, and we are now beginning to understand ribozymes well enough to turn them into useful tools. Work in our laboratory has focused on the development of twin ribozymes for site-specific RNA sequence alteration. To this end, we followed a strategy that relies on the combination of two ribozyme units into one molecule (hence dubbed twin ribozyme).

The twin-arginine translocation (Tat) system transports folded proteins across the bacterial plasma membrane. Three subunits, TatA, B and C, are known to be involved but their modes of action are poorly understood, as are the inter-subunit interactions occurring within Tat complexes. We have generated mutations in the single transmembrane (TM) spans of TatA and TatB, with the aim of generating structural distortions.

Twin-arginine translocation (Tat)-mediated protein trans-port across the bacterial cytoplasmicmembrane occurs only after synthesis and folding of the substrate protein that contains a signal peptide with a characteristic twin-arginine motif. This implies that premature contact between the Tat signal peptide and the Tat translocon in themembranemust be prevented. We used site-specific photo-crosslinking to demonstrate that the signal peptide of nascent Tat proteins is in close proximity to the chaperone and peptidyl-prolyl isomerase trigger factor (TF). ...

DiGIR2 is the group I splicing-ribozyme of themobile twin-ribozyme intron Dir.S956-1,present in Didymiumnuclear ribosomal DNA. DiGIR2 is responsible for intron excision, exon ligation,3¢-splice site hydrolysis,and full-length intron RNA circle formation. We recently reported that DiGIR2 splicing (intron excision and exon ligation) competes with hydrolysis and subsequent full-length intron circularization. Herewe present experimental evidence that hydrolysis at the 3¢-splice site in DiGIR2 is dependent on structural elements within the P9 subdomain not involved in splicing....

The Rieske [2Fe)2S] protein (ISP) is an essential subunit of cyto-chromebc1 complexes in mitochondrial and bacterial respiratory chains. Based on the presence of two consecutive arginines, it was argued that the ISP ofParacoccus denitrificans, a Gram-negative soil bacterium, is inserted into the cytoplasmic membrane via the twin-arginine translocation (Tat) pathway.

Twin-arginine translocase (Tat) is involved in the translocation of fully folded proteins in a process that is driven by the proton motive force. In most prokaryotes, the Tat system transports only a small proportion of secretory proteins, and Tat substrates are often cofactor-containing proteins that require folding before translocation.
