Authors: Тормахова Анастасія , Товмаш Дмитро
Published: December 2024

Розглядається вплив глобалізації на ділову культуру, зосереджуючи увагу на подвійних процесах інтеграції та диференціації, які вона стимулює. Глобалізація сприяє безпрецедентному розширенню зв’язків і доступу до ресурсів, але, водночас, кидає виклик здатності національних культур зберігати свою унікальну ідентичність. Взаємодія між універсальними стандартами та місцевими цінностями формує сучасні бізнеспрактики, підкреслюючи критично важливу роль культурних та етичних принципів у визначенні організаційної поведінки. Окреслюється концептуалізація ділової культури як невід’ємної частини національної культури, вплив масової культури на бізнес-практики, а також проблеми узгодження глобальних стандартів з традиційними цінностями. Досліджується трансформаційна роль цифрових технологій, зокрема блогів і соціальних мереж, у зміні ділової комунікації та стимулюванні інновацій. Підкреслюється, що інтерактивні платформи дозволяють бізнесу підвищувати прозорість власної активності, реагувати на потреби споживачів.

Висвітлюється вплив комунікативних інновацій епохи Інтернету на соціокультурні процеси. Досліджено еволюцію комунікативних інструментів, що зумовлює трансформації в культурному вираженні, соціальних структурахта ідентичності, формуючи майбутнє культурного виробництва та поширення культурних наративів. Розглянуто як цифрові технології сприяють змішуванню культурних кодів, відображаючи тенденції глобалізації. Зауважено, що вказана гібридизація збагачує культурне середовище, але, водночас, викликає занепокоєння щодо т. зв. «ерозії» ідентичності, через переважання у дигітальному середовищі наративів домінуючих культур, що призводить до потенційних аксіологічних конфліктів між традиційними та сучасними підходами. З огляду на результати дослідження констатується, що штучний інтелект, попри свої переваги, створює ризики для соціокультурного і когнітивного благополуччя, змінюючи фундаментальні принципи комунікації та культурного обміну. Зроблено висновок, що Інтернет-технології ставлять суспільство перед необхідністю балансувати між інноваціями та збереженням культурної спадщини.

Drugs in Incretin Based Control of Type 2 Diabetes: Intervention for More Efficacy and Safety
Authors: S S Sreenivas S S Sreenivas
Published: December 2024

Diabetes mellitus (DM) is a global
health disorder due to insulin resistance or insulin
deficiency. T1DM is insulin dependant, while
T2DM, which affects about 90% of all cases,
known as non-insulin-dependent DM. Though
impaired regulation of incretin hormones a
fundamental defect in the pathogenesis of Type 2
diabetes, is not a primary event in the development
of type 2 diabetes, but rather a consequence of the
diabetic state. Glucagon-like peptide-1 (GLP-1)
and glucose-dependent insulinotropic polypeptide
(GIP) are the two important incretin hormones
secreted in small intestine in response to ingestion
of food. Glucagon producing α-cells, participate in
glucose counter-regulation to avoid dangerous
hypoglycemia. Thus major intervention started at
developing DPP-4 inhibitors for T2DM. DPP-4
resistant mimetics, GLP-1 receptor agonists
(incretin mimetics) have been designed.Exenatide
is the first analog of class incretin mimetics
followed by liraglutide. Other smaller molecules of
DPP-4 inhibitors available are vi., sitagliptin,
saxagliptin, linagliptin, alogliptin and
vildagliptin.Four more gliptins, namely
teneligliptin, anagliptin, omarigliptin, and
trelagliptin are also, found effective.

Authors: Kumar Ajay , Manisha Manisha , Yadav Divyadeep , Jha Ranjana
Published: December 2024

MoS2 has drawn much attention towards energy storage devices in recent years due to its high conductivity and good catalytic activity for electrochemical devices. 3D nanoflowers of 1T/2H MoS2 with different particle sizes were synthesized using facile hydrothermal method. Oxalic acid, nitric acid, and ascorbic acids were used during the synthesis method other than Mo and sulfur source, to study the effect on morphology, surface area, and electrochemical activity. X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), High Resolution Transmission Electron Microscopy (HRTEM) and UV-Vis Spectroscopytechnique were used to study the structure, morphology and band gap energy of synthesized nano powders. MoS2 nanoflowers formed using ascorbic acid as a precursor showed high specific capacitance(229 F/g) than other synthesized samples. Structural morphological and electrochemical results showed that MoS2nanostructure material formed with ascorbic acid as a reducing agent can be suitable electrode materials for electrochemical supercapacitorsdevices in the future.
Behavioral Economics: Understanding Human Decision-Making
Authors: Choudhury Sen Sushmita , Verma Dr. Ajeya
Published: December 2024

Behavioral economics, a rapidly growing field that merges insights from psychology and economics, seeks to understand how individuals make economic decisions in practice. Unlike traditional economic theories that assume rational decision-making, behavioral economics posits that humans often act irrationally due to cognitive biases, emotional influences, social factors, and heuristics. This paper explores the key principles of behavioral economics, the role of cognitive biases, and the implications for public policy and business strategy. It also highlights the contributions of seminal researchers such as Daniel Kahneman, Amos Tversky, Richard Thaler, and others, and discusses the growing significance of the field in shaping real-world economic outcomes.
Expression and activity of Ascorbate Peroxidase (APX) enzyme in Persian lime with HLB by the application of resistance elicitors

Published: December 2024

Persian lime is one of the most economically important citrus crops in Mexico, yet its productivity is significantly affected by diseases, with Huanglongbing (HLB) being the most devastating worldwide. Currently, no effective treatment exists to mitigate HLB. However, the exogenous application of resistance elicitors can reduce disease severity by inducing antioxidant response mechanisms in plants under biotic and abiotic stress. These biochemical responses include the production of reactive oxygen species (ROS), which trigger oxidative chain reactions neutralized by antioxidant defense systems. Key enzymes such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) play a role in activating defense-related gene expression. This study aimed to evaluate the gene expression and enzymatic activity of ascorbate peroxidase (APX) in Persian lime plants infected with HLB following treatment with resistance elicitors. Treatments included salicylic acid (SA), gamma-aminobutyric acid (GABA), and their combination (SA+GABA) at 10 mM via foliar application over eight weeks. Gene expression was analyzed through RT-PCR, and APX activity was quantified. Results indicated that SA induced the highest APX expression and enzymatic activity, followed by SA+GABA and GABA alone. The findings demonstrate that chemical elicitors enhance APX gene expression and enzymatic activity, contributing to the plant's defense against HLB.

Growing need for renewable energy and addressing challenges associated with indiscriminate wastes disposal has necessitated harnessing wastes to wealth. The study investigated parameters determining the physicochemical composition of palm oil mill effluent (POME) generated at Agricultural Development Authority Palm (ADAPALM) and palm oil mills in its catchment communities, located at Ohaji/ Egbema Local Government Area of Imo State, Nigeria and their implications on environmental health and treatment approaches required. Survey research design was used. From a randomly sampled small-scaled mill in each community, and for the lone medium and large-scaled mills, four homogenous samples of POME were collected from sampled small, medium and large-scaled mills for laboratory analysis of potential of hydrogen (pH), dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total carbon (TC), total solid (TS), total suspended solid (TSS), total organic carbon (TOC), total nitrogen (TN), total kjeldahl nitrogen (TKN), ammonia nitrogen (NH3-N), Manganese (Mn), Nickel (Ni), Iron (Fe), Copper (Cu), Chromium (Cr), Cadmium (Cd), Potassium (K), total phosphorus (TP), Calcium (Ca), and Magnesium (Mg) using standard methods for wastewater analysis as described in American Public Health Association. Data was analysed using multivariate analysis of variance, and showed that the physicochemical composition of POME was significantly different (p<0.01) across milling-scales, types of FFBs and seasons. The pH=11.728±0.467 and 4.10563±0.030, BOD= 52.042± 1.669 and 233.125±10.674; TSS=14421.748±2431.870 and 974.344±29.764; TN= 347.918±7.371 and 468.92500±31.315; TP=127.890±1.478 and 26.476±6.339 for dry and wet seasons respectively, and COD=3731.250±154.574 for dry season only were not within the acceptable wastewater discharge limits. The pH, Cd, Ni, Cu, K and organic content across seasons highlight specific concerns in the wastewater treatment. The study has simultaneously addressed a wider scope of independent variables that define the composition of POME, and required approaches necessary to revert environmental degradation and promote green energy access in the area.

The modern approach to building neural networks evolves and continues to develop in
improving the mathematical model of neuron functioning, which leads to new differences from real
biological analogues, since a highly simplified model of the basic element (neuron) is used to model
modern neural networks. The purpose of this work is to calculate the information capacity of a neural
network built on a biological neuron, to provide evidence of the prospects for studying methods for
building a neural network using biological neurons. A mathematical description of the main structural
elements of a biological neural network is given: neurons, axons and dendrites and neurotransmitters, as
key parameters for data exchange between neurons. It is shown that biological neural networks, unlike
artificial ones, require up to 6000 times less energy for computing work and lower production costs.
Artificial neural networks are an expensive technology due to the high costs of training and development,
despite the fact that many manufacturers mass-produce integrated circuits. It was found that using a
biochip it is possible to reduce these costs many times, because living cells learn much faster, are
distinguished by high neuroplasticity. But in creating a neural network based on a biological neuron,
problems were noted: maintaining the vital activity of a biological neural network; synthesis of cells for
the system; as well as integration of biomaterials and a processor. In the work, the information capacity
of a biological neural network was calculated and compared with different types of artificial ones
(unidirectional sigmoid neural network, radical neural network, recurrent neural networks, recurrent
networks based on a perceptron, neural networks with self-organization based on competition, fuzzy
neural networks). The results of experimental calculations showed that a neural network built on
biomaterials is 92% higher in information capacity compared to a computer model, which indicates the
achievement of the goals set in the work.

Unlocking the gene potential of both humans and plants is an unsolvable task for existing
computers, so many problems are solved in a roundabout way. The problems of high-speed processing of
large data sets, studying the structure of proteins and the human genome, or modeling complex physical
systems are still relevant due to the slowness of classical computers. The potential of quantum computers
was investigated in the work using a theoretical experiment to assemble the human genome. A classical
computer with an AMD A10 4600M processor with 4 cores and a quantum computer with a Bristlecone
processor with 72 qubits act as comparison elements. It was found that the quantum device was 3.69
1014 times faster than the classical one, and conclusions were made about the potential application of
this technology. An approach to improving computational algorithms in biosystems on quantum
computers using the example of one qubit by creating an ideal quantum computer with a constant
coherent state was proposed, i.e. in such a computer there is no influence of the external environment
leading to decoherence. Thus, external signals that set the calculation parameters will carry out precise
control of the calculation. The state of the ideal quantum computer changes under the action of some
computational transformation according to the formed algorithm at each moment of time. From a formal
point of view, such transformations have the form U ⊗ I, where U is the matrix acting on the selected
qubits or qubit, I is the identity matrix acting on the remaining qubits. The resulting quantum algorithm
implies the sequential application of such transformations from one qubit to another.

The permissible wear of bearing seats does not exceed 0.3 mm, therefore, when restoring
with polymer composites, it is required to mix no more than 100 g of material at a time. The issue of
mechanical mixing of such small volumes has not been considered previously and requires research.
Devices with stirrers manufactured according to GOST 20680-200 cannot be used for mixing since they
have excess vessel volume (more than 0.01 m3). A method has been developed for calculating the design
and operating modes of a turbine stirrer when mixing a nanocomposite solution intended for restoring
bearing seats. The article presents the design parameters of three mixing devices of different sizes. The
technological mode of 3D printing of device parts and a turbine stirrer is described. A Flying Bear Ghost
5 3D printer is used, and PETG plastic is the consumable. An original composition of an elastomeric
nanocomposite filled with non-metallic nanoparticles has been developed. The material has unique
deformation and strength properties. The specific work of destruction of this nanocomposite is 2.54 times
higher than that of elastomers filled with metal nanoparticles and 1.24 times higher than that of carbon
nanotubes. An experiment was conducted that confirmed the applicability of the developed calculation
program to solutions of elastomeric nanocomposites filled with non-metallic nanoparticles. High
convergence of the calculated values of the optimal rotation frequency of the turbine mixer during mixing
with the actual ones was established (the discrepancy is no more than 6%). The efficiency of mixing the
nanocomposite solution was assessed by two criteria. The first criterion was the transmission coefficient.
The value was determined after manual and mechanized mixing and compared. The second criterion was
the strength of the nanocomposite samples after various mixing modes. The higher the quality of mixing,
the greater the strength of the samples. The study showed the unsuitability of the first criterion. This is
explained by the optical properties of the filler nanoparticles, which do not absorb but reflect the light flux.

Protection of structural materials from atmospheric corrosion remains a pressing issue for
corrosion engineers in industry and agriculture. For this purpose, the use of various types of paint and
varnish coatings is promising. The prospects for using a number of substances (sodium nitrite, cysteine,
sodium benzoate, benzotriazole) as inhibitors of flash corrosion for creating aqueous primers for metal
based on styrene-acrylic dispersions have been studied. It has been shown that the obtained coatings
have high adhesion to St3 steel. The efficiency of anticorrosive protection of steel in the presence of
inhibited primers has been studied using gravimetric and electrochemical methods. It has been shown
that the best protective effect (Z) is possessed by a coating with benzotriazole (Z = 83%) in distilled
water. In 0.5 M NaCl The efficiency of inhibited coatings in 0.5 M NaCl differs little from each other and
is within Z = 50 – 60%. According to the results of tests in the climatic chamber, the leading position is
occupied by the primer with sodium benzoate, Z = 94%. This coating also withstands the impact of the
aggressive atmosphere in the salt fog chamber longer than others. The analysis of polarization curves
shows that in a 0.5 M NaCl solution with a short-term exposure in the solution, benzotriazole is the most
effective inhibitor. The conductivity of all the inhibited coatings under study over 6 days is lower than
that of coatings without an inhibitor. Thus, benzotriazole and sodium benzoate can be selected as the
most promising substances for further testing in order to manufacture a commercial product.

Turbidity of drinking water is one of the most important indicators of its quality, according
to sanitary rules and regulations it should not exceed 2.6 units of turbidity by formazin (TUF). The use of
turbid water in technological processes often leads to failure of equipment, communications, and also
contributes to the deposition of mineral and organic particles on the internal surfaces of water pipes and
tanks. The purpose of the study is to determine the optimal design and operating parameters of the device
for cleaning and disinfecting water, upon reaching which turbidity will not exceed the maximum
permissible values. A device combining two stages of water purification from large and small impurities,
as well as a stage of its disinfection, is proposed. Theoretical and laboratory studies of the developed
device were carried out, during which the effect of water supply and the pore size of the filter element on
the turbidity index of water was determined. It was found that when using a filter element with pore sizes
of 1 μm and 5 μm, as well as with a feed of 2 l/min, the efficiency of reducing turbidity was 51% with an
approximation reliability value of 0.9, which indicates the achieved efficiency of the device. It was also
determined that an increase in the water flow rate when it passes through the device is accompanied by
an increase in turbidity. The studies were carried out using a turbidity analyzer that operates using the
nephelometry method and determines the scattering of light directed at an angle of 90° by suspended
particles, which ensures the greatest sensitivity of this device.

In the context of the development of the agro-industrial complex (AIC) of the Russian
Federation, the production of fruit and vegetable products is of particular importance. They are
characterized by a high moisture content and a short shelf life, therefore they require the creation of
special conditions for the preservation of vitamins and other valuable biological substances, for example,
by drying. Since the drying process can be multi-stage, it is necessary to use effective technological
approaches to control the drying mode, and this concerns the automation of all elements, as well as a
combination of exposure to various physical fields on the dried material. A drying unit operating in
automatic mode was considered. Thermal analysis and recording of the heater power using a multimeter
were carried out. The study of the temperature field distribution on the heater surface in the heat
emission mode was carried out by a contactless method using a thermal imager. The article presents a
mathematical model of a system for processing fruit and vegetable products, which includes such technological operations as microwave and vacuum drying. For the effective operation of the unit, a
control system was used that provides full automation of drying. The presented mathematical model
makes it possible to find the dependence of drying time on power, which allows for efficient distribution
of the power of drying systems at different stages. Drying of plant materials (pumpkins to 20% humidity
and then reducing humidity to 5-12% using microwaves) is efficient.

The article analyzes the performance properties of diesel fuel that affect the processes of its
mixture formation, ignition and combustion in the internal combustion engine (ICE). The main factors
leading to intensive carbon formation, as well as methods and means for its cleaning, are identified. A
rational design of a device for in-place cleaning of ICE parts from carbon is presented, which includes a
steam generator, a mixer-doser, a nozzle with a jet; a dosing needle, a diffuser. The steam generator on
the exhaust manifold of the engine has an input connected to a water tank through a water pipeline, the
output is carried out using a steam tube. It is connected to a mixer-doser of steam, introduced into the
intake manifold of the ICE through an insert containing a chamber for automatic dosing of steam
depending on the load on the ICE. The nozzle with the jet in the lower part of the water tank is connected
to the water pipeline, in the upper cover of the chamber there is a limiting screw and a spring, resting
with one end on the cover, and with the other on the membrane of the chamber, rigidly connected through
a rod with a metering needle. The metering needle in the form of a cylindrical rod with a conical end
enters the conical hole in the body of the steam dispenser. In the body of the insert in the intake manifold,
a diffuser is rigidly attached, into which the nozzle from the steam dispenser is brought out, turned with
the outlet hole towards the engine. The results of the conducted experiments on testing the developed
technical solutions on the KI-5540 test bench are presented, which showed that without significant
changes in the design of the standard ICE power supply system by supplying 17% steam to the
combustion chamber, it is possible to obtain the best technical result in restoring the engine's
performance characteristics without taking the equipment out of operation, and also to extend its service
life due to the complete cleaning of ICE parts from carbon deposits, which have an initial thickness of
1.72 mm.

The conducted analysis of the humus balance dynamics in the Tambov region in 1971-2018
showed a steady decrease in the content of organic matter in the soil, which can be associated with
insufficient livestock in agricultural organizations, problems with the use of technologies for processing
and applying organic fertilizers. The amount of organic matter introduced into the soil must be increased
to replenish the humus content in the soil. A solution to this problem is proposed using green manure. The
costs of their cultivation are 3-4 times less than the preparation and application of manure. The need for
a differentiated approach to maintaining fertility, taking into account local conditions, is shown. Field or
forage crop rotation with green manure fallow is recommended for the Tambov region, depending on the
focus of the enterprise (crop production or livestock farming). Three technologies for processing green
manure fallow, including mowing, crushing and incorporation of plant mass, are proposed. The
technological scheme using a machine-tractor unit, including a tractor of the MTZ-80L class, a frontmounted mower-chopper developed by the authors and a disc harrow, is recommended as the most
promising. During the forward movement of the unit, the stems of the plants are bent forward in the
direction of travel, due to the trough-shaped body they are formed into an array, which enters the
crushing zone at an angle that ensures supporting cutting of plants with a minimum cutting area.
Operational tests of the mower-chopper of green manure crops and stubble residues ISN-2.2-1 showed
that the technological process of crushing plants is carried out stably and with a quality that meets
agrotechnological requirements.

Heavy agricultural machinery used for field work has a negative impact on the soil,
reducing its physical, chemical and biological potential as a result of over-compaction. Over-compaction
negatively affects key soil functions, the main one of which is productivity. Although compaction is a wellrecognized problem, it is still difficult to quantify the level of environmental damage caused by the chassis of various equipment to the soil-crop system. This is especially true for vehicles operating in
harvesting and transport units. The paper offers a comparative assessment of the impact of the chassis of
ZIL-MMZ-554, KAMAZ-53205 and KAMAZ-65207 trucks on the yield of subsequent crops in the crop
rotation. It was found that under typical winter wheat harvesting conditions in the central zone of the
Krasnodar Territory (1000 m track length and 60.4 c/ha yield), the studied trucks cover an average of
15.1 to 18.1% of the entire field area with tracks. Soil compaction by the running gear of vehicles may
cause a decrease in its productivity. Thus, using a vehicle in a harvesting and transport unit that serves
one combine harvester per transport cycle may reduce the yield of the next crop in the crop rotation by
3.1%, serving two combine harvesters - by 6.7-7.2%. When driving empty vehicles over stubble, the risks
of reducing soil productivity are minimal: the predicted overall decrease in the yield of the next crop in
the crop rotation will not exceed 1%.

Harvesting, which also includes post-harvest processing, is of great importance in grain
production. The components of seed processing technology include preliminary, primary, including
secondary cleaning, as well as sorting and storage. The grain heap (moisture content up to 35%) coming
from combines is transported to the grain threshing floor, processed using mobile equipment, which
includes a granular material thrower. The material of the study was technical means for throwing grain,
which are widely used in cleaning, sorting, including transportation, cooling, drying of grain and its
processed products. A review of literature sources, patent search and their analysis were used as
research methods. Generalization of the obtained material provided the basis for solving the technical
problem of improving the device for throwing granular materials at a patentable level. The proposed
improved device for throwing granular materials makes it possible to improve the quality of the
transported processed material by reducing its damage and injury. Rubber coatings on the sickle-shaped
part of the blade, which is recommended to be installed at an angle of 30 to 40 degrees to the initial
radius of the drum in the opposite direction from the rotation of the drum, are provided to reduce the
impact force of the grain particle on the blade at a constant value of the angular velocity. This forms a
rational loading of the blades at the beginning, and then a shock-free unloading. The design feature of
this technical device allows to improve the compactness and reliability of operation, as well as reduce
metal and energy consumption.

The issues of evaluation of technological parameters of hose sprinklers (HS) operating in
positions or in motion are considered. The following technological parameters: precipitation layer per
pass, average rain intensity, effective irrigation coefficient and average diameter of raindrops were
calculated in the course of theoretical studies. Experimental studies on determination of rain quality were
conducted in Moscow region during irrigation of cabbage in cassettes and radish. Rain distribution was
studied on two variants of HS working bodies in laboratory and production conditions. Irrigation radius
by measuring with a tape the flight range of drops from HS nozzles and rain quality parameters were
determined. Precipitation layer per pass was determined using 0.5 l rain gauges during operation of the
sprinkler in motion at a pressure of 0.3 MPa. Studies of HS samples showed that when equipped for
operation in motion, they provide water consumption of 0.56…0.60 l/s at a pressure of 0.2 MPa and
0.83…0.90 l/s at a pressure of 0.3 MPa; the movement of the SD samples should be carried out at a speed
of 0.08 ... 1.0 m / min; the highest quality irrigation is achieved when arranging the SD with overlapping
according to the scheme of 10x10 m; the rain layer per pass depends on the water pressure; the
coefficient of effective irrigation at a pressure of 0.2 MPa and when arranging every 21 m was 0.74.
Technical and economic calculations confirm the high economic efficiency of the created technical
means, ensuring a reduction in capital costs by 60%. The DM-1 SD has passed state tests and is
recommended for serial production. Hose sprinklers of the DS-0.6 and DS-1 type and their modifications
for irrigation of small areas (up to 1 ha) on the basis of the conducted research and tests will find wide
application in sprinkling irrigation of various agricultural crops in farms, gardening, household and
individual farms.
