Published: July 2020

Aim. Agrobacterium-mediated transient expression using viral-based vectors is one of the most effective method for recombinant protein production in plant. Transient expression of GFP using viral-based module system was studied in plant tissue culture in vitro. Methods. Regenerated shoots and callus clones of Nicotiana benthamiana were agroinfiltrated with viral-based module system. Protein extracts from GFP-positive tissues were resolved by non-reducing polyacrylamide gel electrophoresis. GFP from gel was eluted and GFP fluorescence was measured by fluorescence spectrometry with excitation filter at 395 nm and emission filter at 510 nm. Results. Regenerated shoots and callus clones lines accumulated GFP at 242.0±0.7 and 221.6±4.1 μg per g fresh tissue, respectively. The obtained level of transient expression is comparable with other plant production systems in early stage development. Conclusions. The developed technique shows promise for production of therapeutic proteins and antigens in the short term (14–16 days) by transient expression system in plant tissue culture in vitro.
Keywords: viral-based module system, transient expression, recombinant proteins, plant tissue culture, GFP.

Published: July 2020

Aim. The investigation of the T3 transgenic sunflower plants osmotic tolerance there were developed. The levels of free proline in plant shoots and roots were estimated. Methods. Mature sunflower plants (T3 and wild type) were cultured in standard pots. Those genotypes were tested during 12-day artificial drying. The levels of free proline in plant shoots and roots were measured. Results. The proline contents in transgenic plants preferred those parameters of control plants both under normal and stress conditions. The proline levels in shoots and roots increased in all genotypes cultivated under stress conditions. The shoot/root proline ratio of control plants was constant during whole experiment, while in T3 plants this parameter changed due to high elevation in roots. Conclusions. The changes of shoot/root proline ratio of T3 plants were the result of free proline transfer among plant organs.
Keywords: Helianthus annuus L., transgenic plants, L-proline, shoot/root proline ratio.

Published: July 2020

Aim. The purpose of investigation was to study the effect of microwave irradiation of varying intensity to lifespan in adults of Drosophila melanogaster Meig. Methods. Experiments were carried out on wild type Oregon-R strain. Two-day-old flies were irradiated by microwaves (frequency – 36.64 GHz, exposure time – 10 sec). The power density was 0.01, 0.1 and 1 W/m2. Lifespan was examined in the irradiated and non-irradiated (control) flies. Results. The females showed a reduction in life expectancy by power density of 0.01 and 1 W/m2, median decreased respectively by 6.0 % and 8.7 % (p < 0.05). In males, reduced life expectancy was found by microwave power density of 1 W/m2, the median fell by 11.8 % (p < 0.05). No effect was detected by irradiation intensity of 0.1 W/m2. Conclusions. Exposure to microwave irradiation can reduce the lifespan in Drosophila adults. The effect depends on the sex and power density of microwaves.
Keywords: Drosophila melanogaster, lifespan, non-ionising radiations.

Aim. Among the problems that arose after the accident at the Chernobyl nuclear power plant belongs to the most important problem of the transmission effect of genomic instability through irradiated gametes parents first generation of their descendants. Determine the frequency of chromosomal aberrations in bone marrow cells of the offspring of rats that were exposed to the radioisotope 131I. Methods. Cytogenetic analysis of bone marrow cells in the offspring of the first generation of irradiated both parents exposed the females and intact males and irradiated malesan dintact females. Results. The results of experimental studies have shown that in the descendants of irradiated 131I females, the frequency of chromosome aberrations in bone marrow cells exceeds the control level (4.83 ± 0.59 % experience, 0.83 ± 0.36 % control). In offspring of exposed parents detected chromosomal abnormalities in bone marrow cells. The frequency of aberrant metaphases was significantly higher than the control level (4.16 ± 0.54 % and 0.83 ± 0.36). Cytogenetic analysis of bone marrow cells descendants of rats exposed to 131I males showed that chromosomal damage detected not statistically different from controls. Conclusions. Cytogenetic analysis showed the presence of chromosomal aberrations in the bone marrow cells of the first generation progeny. The frequency of chromosome aberrations was significantly higher due to specific markers of radiation exposure: paired fragments, dicentric and acentric rings. Results of the study confirmed the findings of other authors on the high sensitivity of the organism in the prenatal period to the mutagenic effects of radiation on the induction of chromosomal instability transgenerational.
Keywords: rats, iodine-131I, offsprings, the first generation, cytogenetic effects, bone marrow cells.

Published: July 2020

Aim. As the genetic code is actually a protein’s code so still leaves in the shade the answer to the question that is our aim. Why in the certain time, in the right place happens the proper phenomenon during the formation of various configurations of cells, organs and organisms. Methods. Studying and analyzing the various scientific literature, we sought to theoretically give an answer to this question. Results. Synthetic theory of evolution is considering genome as a passive structure that encodes and transmits accidentally arising variations of genotypes. However, in recent years become more known the facts that indicate the genome is an active system that self-regulated and self-organized. The genome includes not only the material for evolution, but the mechanisms of its application for the creation of new genotypes and phenotypes in the future for active participation in the process of their own evolution. The modern scientific data confirm that most evolutionarily success is the genome that is capable of change. This means that in the genome there are mechanisms that control and create diverse and concerted restructuring of DNA. Conclusions. Evolution is the continuous development in which organisms survive. The evolution is typical for all levels of nature. The main active factors of evolution are a mutation, a recombination, a hybridization and a transgenesis.

Published: July 2020

La forte prévalence de la victimisation sexuelle chez les jeunes et les possibles répercussions associées incitent au développement de programmes de prévention efficaces. Or, l’implication des parents afin de prévenir cette forme de violence est reconnue comme nécessaire : en ce sens, le programme Empreinte – Agir ensemble contre les agressions à caractère sexuel inclut un volet leur étant destiné, offert par l’entremise de courtes vidéos accessibles par le Web. L’objectif de cette intervention est d’amener les parents à jouer un rôle actif dans la prévention de la violence sexuelle en les incitant à créer des opportunités de discussions auprès de leur jeune. Cette étude vise à évaluer les effets de ces six capsules vidéo auprès de parents d’adolescent.es. Les résultats démontrent que le visionnement des vidéos a permis aux 78 parents d’améliorer leurs connaissances face à la violence sexuelle, leurs attitudes exemptes de préjugés et leur sentiment d’autoefficacité. De plus, 68 % des parents ont affirmé avoir entamé une discussion en lien avec la violence sexuelle avec un.e jeune de leur entourage dans le mois suivant leur visionnement des capsules vidéo. Enfin, l’appréciation envers les vidéos est fortement positive. L’utilisation de vidéos offertes par le Web afin d’impliquer les parents dans la prévention de la violence sexuelle auprès d’adolescent.es s’avère donc une avenue prometteuse.
Fluid Mechanics
Authors: Chhabra Raj P. , Patel S.A. 
Published: July 2020

AbstractThis article provides an overview of the fundamentals and common applications of fluid mechanics in engineering settings, especially in the context of chemical and process engineering. Starting with the definition of a fluid, types of fluids, concept of continuum, and the Eulerian and Lagrangian viewpoints are introduced. This sets the stage for the development of the Reynolds transport theorem required to apply the laws of physics (conservation of mass and energy and Newton's laws of motion) to open systems in moving fluids. Integral and differential forms of these laws as applied to the moving fluids are obtained. Selected applications such as the estimation of frictional pressure drop in pipes and in packed columns are presented in detail. Similarly, the external flow of fluids over variously shaped objects such as sphere, cylinder, and circular discs is discussed next. The effects of solid boundaries on the detailed flow kinematics such as separation of shear layers and various flow regimes which directly influence the macroscopic flow are discussed briefly. The preceding treatment limited thus far to simple Newtonian fluids is then extended to more complex fluids such as non‐Newtonian and/or the flow of multiphase systems (gas–liquid, liquid–liquid, and gas–solid) in pipes, which are discussed in brief. The commonly used experimental tools in fluid mechanics for velocity, flow, temperature, and pressure measurements in single and multiphase flows are also introduced briefly, followed by the measurement of average holdup in multiphase flow situations. A short discussion of the other important areas of fluid mechanics not covered here is offered, supported by an extensive bibliography for further reading.
Surface Functionalization of Black Phosphorus by Cu: Effective Electron Doping and Enhanced Photoresponse
Authors: Zheng Yue , Yang Hang , Han Cheng , Mao Hong Ying 
Published: July 2020

AbstractBlack phosphorus (BP) emerges as a monoelemental 2D semiconductor with a direct bandgap, exhibiting a hole‐dominated ambipolar transport characteristic. The modulation of charge carriers type and concentration is of great necessity for its applications in electronic and optoelectronic devices. Herein, the effective electron doping of BP by surface functionalization of copper (Cu) is demonstrated. Moreover, the electron mobility of BP increases from 63 to 156 cm2 V−1 s−1 after Cu modification. The formation of electron accumulation layer within BP after Cu modification is further revealed by in situ photoelectron spectroscopy characterizations. No chemical reaction is observed at the Cu/BP interface where a notable electron transfer from Cu to BP occurs indicated by an ≈0.20 eV shift of P 2p peak to high binding energy after Cu functionalization. With the formation of local electric field at the interface, the dissociation of photogenerated excitons is facilitated, leading to an ≈6 times enhancement of the photoresponse for Cu‐modified BP.

AbstractAqueous rechargeable Ni‐Fe batteries featuring an ultra‐flat discharge plateau, low cost, and outstanding safety characteristics show promising prospects for application in wearable energy storage. In particular, fiber‐shaped Ni‐Fe batteries will enable textile‐based energy supply for wearable electronics. However, the development of fiber‐shaped Ni‐Fe batteries is currently challenged by the performance of fibrous Fe‐based anode materials. In this context, this study describes the fabrication of sulfur‐doped Fe2O3 nanowire arrays (S‐Fe2O3 NWAs) grown on carbon nanotube fibers (CNTFs) as an innovative anode material (S‐Fe2O3 NWAs/CNTF). Encouragingly, first‐principle calculations reveal that S‐doping in Fe2O3 can dramatically reduce the band gap from 2.34 to 1.18 eV and thus enhance electronic conductivity. The novel developed S‐Fe2O3 NWAs/CNTF electrode is further demonstrated to deliver a very high capacity of 0.81 mAh cm−2 at 4 mA cm−2. This value is almost sixfold higher than that of the pristine Fe2O3 NWAs/CNTF electrode. When a cathode containing zinc‐nickel‐cobalt oxide (ZNCO)@Ni(OH)2 NWAs heterostructures is used, 0.46 mAh cm−2 capacity and 67.32 mWh cm−3 energy density are obtained for quasi‐solid‐state fiber‐shaped NiCo‐Fe batteries, which outperform most state‐of‐the‐art fiber‐shaped aqueous rechargeable batteries. These findings offer an innovative and feasible route to design high‐performance Fe‐based anodes and may inspire new development for the next‐generation wearable Ni‐Fe batteries.
Quantifying the effect of polarity on the behavior of mixtures of n‐alkanes with dipolar solvents using polar soft‐statistical associating fluid theory (Polar soft‐SAFT)
Authors: Alkhatib Ismail I. I. , Vega Lourdes F. 
Published: July 2020

AbstractWe present results concerning the phase equilibria and excess properties of binary mixtures of n‐alkanes with a range of fluids from low to high dipolar strength, namely 1‐hexene, chloroform, dichloromethane, tetrahydrofuran, acetone, dimethylformamide, and N‐methyl pyrrolidone modeled by polar soft‐statistical associating fluid theory. Polar interactions are considered through the theory of Gubbins and Twu, extended to chainlike fluids by Jog and Chapman, and a priori fixing the polar parameters of the pure fluids, instead of fitting to experimental data. The equation provides accurate predictions for low to moderate dipolar molecules with n‐alkanes, while the induced dipoles created by very strong dipolar fluids (μ ≥ 3.5 D), is implicitly considered by the appropriate selection of pure component parameters and a binary parameter which can be transferred to predict other properties. The equation is used to systematically study the effect of asymmetrical energy scales between polar and nonpolar fluids on vapor–liquid equilibria and excess properties.
