Controlling the topological sector of magnetic solitons in exfoliated Cr1/3_{1/3}NbS2_2 crystals

We investigate manifestations of topological order in monoaxial helimagnet Cr$_{1/3}$NbS$_2$ by performing transport measurements on ultra-thin crystals. Upon sweeping the magnetic field perpendicularly to the helical axis, crystals thicker than one helix pitch (48 nm) but much thinner than the magnetic domain size ($\sim$1 $\mu$m) are found to exhibit sharp and hysteretic resistance jumps. We show that these phenomena originate from transitions between topological sectors with different number of magnetic solitons. This is confirmed by measurements on crystals thinner than 48 nm --in which the topological sector cannot change-- that do not exhibit any jump or hysteresis. Our results show the ability to deterministically control the topological sector of finite-size Cr$_{1/3}$NbS$_2$ and to detect inter-sector transitions by transport measurements.Comment: 7 pages, 8 figure

Innovational methods of development of intellectual labor for economy’s security

The notion “development of intellectual labor for the purpose of economy’s security” is viewed as development of society’s intellectual potential that includes the protected socio-economic information, developed by a person or a group of persons. The social factors that reduce economic security and their consequences in economy are given, namely: negative dynamics of implementing new progressive technologies into production, insufficient coordination of work in the sphere of innovational development, etc. The forms of intellectual development of human resources (intellectual development of personality, control over intellectual information) are offered, which bring the country’s economy to competitiveness and security. The traditional and innovational methods of intellectual labor development are studied (studying in universities and colleges, increase of personnel’s qualification in view of academic degrees (Ph.D., doctor of economics), as well as receipt of economic information through Internet resources, scientific publication, statistical information, etc.), as well as the methods of development of IT services and methods of prevention of intellectual diversions and violation of information confidentiality. It is offered to implement the program of equal initial possibilities for intellectual development of human resources in view of access to higher education, creative activities, as well as legal protection for everyone, etc. Analysis of implementation of innovational methods of intellectual labor development supposes planning activities in view of development of intellectual labor for the purpose of the region’s economy’s security.peer-reviewe

THE INFLUENCE OF MILK-CLOTTING ENZYMES ON THE FUNCTIONAL PROPERTIES OF PIZZA-CHEESES

The effect of the type and dose of milk-clotting enzymes (Chy-max® M based on recombinant camel chymosin, Fromase® TL based on Rhizomucor miehei protease) on the physicochemical, functional properties and shelf life of pizza-cheeses was studied. When using a low dose of milk-clotting enzymes (MCE) for milk coagulation (250–1100 IMCU per 100 kg of milk), cheeses were obtained with an increased moisture content (55–57%), excessive acidity (pH 4.8–4.9) and texture defects (incoherent, crumbly, with separation of free moisture). This is due to the formation of a weak curd, which releases moisture poorly during processing. The use of an increased dose of MCE makes it possible to obtain a denser curd, better releasing moisture. Cheese produced with a high dose of milk-clotting enzymes (2000–2800 IMCU per 100 kg of milk) had a lower moisture content (52–53%) and lower acidity (pH 5.0–5.1). The protein matrix is more hydrated in these cheeses, which ensures its better water holding capacity and a more homogeneous and cohesive texture. The use of an increased dose of MCE with a high total proteolytic activity (Fromase) gives undesirable consequences in the form of accelerated proteolysis of cheese mass proteins, rapid loss of functional properties of the cheese, and a decrease in the shelf life of cheese (less than 60 days). Cheese production using an increased dose of MCE with a low level of total proteolytic activity (Chy-max M) allows achieving a low level of proteolysis during cheese ripening and increasing its shelf life

(E)-2-(hydroxystyryl)-3-phenylquinazolin-4(3H)-ones: Synthesis, photochemical and luminescent properties

The new (E)-2-(hydroxyarilethenyl)-3-phenylquinazolin-4(3H)-ones with various substituents in phenyl fragment were synthesized. The effect of electron donor and acceptor substituents (±M) in quinazolinones on luminescence intensity and dual emission in 550-650-nm wavelength range was shown. The fact of the reversible photo/thermal E-Z isomerization for several substances was established. The (E)-2-(5-chloro-2-hydroxystyryl)-3-phenylquinazolin-4(3H)-one had shown the best combination of photochemical (E-Z isomerization) and photophysical properties. The (E)-2-(2-hydroxy-5-morpholinostyryl)-3-phenylquinazolin-4(3H)-one had revealed the best ESIPT-luminescence (Φrel = 5.3 %). © Arkat.
