Responses of Apple Plants to Salinity Stress
Authors: ARAS Servet , EŞİTKEN Ahmet 
Published: July 2019

Salt stress is a common agricultural problem that
affects both quantity and quality of fruit crops. Responses of rootstocks
against salinity possess importance due to demonstrating stress tolerance.
Little is known about the early responses of apple plants to short term
salinity. In our study, we investigated the physiological responses of an apple
plant cv Fuji grafted onto M9 and MM106 rootstocks against 35 mM NaCl stress.
After 1 month, salt-treated plants exhibited decreased chlorophyll content
(SPAD). Salt stress decreased stomatal conductance values of Fuji/M9 and
Fuji/MM106 by 17.0 and 30.1%, respectively when compared with own control.
Membrane permeability decreased by 21.3 and 22.0% in salt-treated Fuji/M9 and
Fuji/MM106, respectively compared with own control. Reduction due to salt
stress in SPAD value, stomatal conductance and leaf relative water content and
increase in leaf temperature and membrane permeability were greater in
Fuji/MM106 than in Fuji/M9, suggesting that under short term salinity toxic
effects of NaCl were less in Fuji/M9.
Necessary condition for solvability of the control problem of an asynchronous spectrum of linear almost periodic systems with trivial averaging of the coefficient matrix
Authors: Demenchuk A. K. 
Published: July 2019

We consider a linear control system with an almost periodic matrix of coefficients. The control has a form of feedback and is linear in phase variables. It is assumed that the feedback coefficient is almost periodic and its frequency modulus, i.e. the smallest additive group of real numbers, including all Fourier exponents of this coefficient, is contained in the frequency module of the coefficient matrix.The following problem is formulated: choose such a control from an admissible set so that the closed system has almost periodic solutions, the frequency spectrum (a set of Fourier exponents) of which contains a predetermined subset, and the intersection of the solution frequency modules and the coefficient matrix is trivial. The problem is called the control problem of the spectrum of irregular oscillations (asynchronous spectrum) with a target set of frequencies.The aim of the work aws to obtain a necessary solvability condition for the control problem of the asynchronous spectrum of linear almost periodic systems with trivial averaging of coefficient matrix The estimate of the power of the asynchronous spectrum was found in the case of trivial averaging of the coefficient matrix.

Published: July 2019

Composites based on calcium phosphates in the matrix of biopolymer (citrated plasma and fibrin) were synthesized in neutral and alkaline medium. At pH 7 brushite composites were obtained, whereas at pH 11 amorphized hydroxyapatite was precipitated. Disruption of precipitation conditions led to the formation of tricalcium phosphate impurity, which was detected by XRD after thermal treatment of composites at 800 °C. Composition and morphology of calcium phosphates did not depend on biopolymer nature. To determine bioactivity degree, composites were incubated in model Simulated Body Fluid (SBF) for 75 days. It was found that composites based on amorphized hydroxyapatite incorporated in biopolymer matrix have maximum growth of biomimetic layer of apatite.

Authors: Senin P. V. , Stanishevskii L. S. , Akayeu Y. B. 
Published: July 2019

A convenient three-step method for synthesis of heptyl (4-triﬂuoroacetyl)benzoate, an important neutral anion carrier, has been developed. The key step of the method is acylation of toluene by triﬂuoroacetic anhydride in presence of aluminium chloride at –8 – –10oC. The procedure gives high overall yield and, unlike the earlier methods, does not include any organometallic reagents, therefore allowing scaling it up to several hundred grams, that makes the target compound much more readily available.

Published: July 2019

The article describes a possible way of introducing nanoscale powders into energy-saturated heterogeneous composite materials (ECM). By the example of polydispersed nanoscale carbon, the main well-known methods for introducing nanoscale components into dispersed and high-viscosity colloidal systems have been studied, their effectiveness has been evaluated, and limitations have been revealed. The main influencing factors on the uniform distribution of nanoscale components in the volume of the composite material and the ways of leveling their influence have beenfound. A technological scheme has been proposed for increasing the distribution uniformity of nanoscale components due to their preliminary deposition on the surface of the material prevailing in quantity of dispersed component while limiting the growth of its specific surface as a method of further reduction of the viscosity of the energy-saturated heterogeneous composite material at the stage of mixing its liquid and solid phases.The rate of change of the form factor, specific surface and distribution of the nanoscale diamond-containing additive over the particle surface of ammonium salt of perchloric acid has been studied depending on the modes of mixing the components in a gravity mixer. Acceptable technological mixing modes have been found.The main tasks of further study of phenomena arising at the phase boundary when introducing nanoscale additives into the dispersed medium of ECM have been determined.
