As Pension fund system is a cornerstone of countries economy, policymakers across the globe are still discussing about universal effective pension fund systems and struggling to implement and fit it to the country’s economy demography and financial system. From this point the main objective of this research topic was to test the effectiveness of new pension system reform in Georgia. It focuses on whether the reform will have positive effects on tackling poverty among elderly and bring to Georgian people real prosperity. The pension fund system represents the essential part of the economic policy. Moreover, it defines the social and political stability and future the development of the state economies. By other words, the simple objective of the pension system is to pay pensions to workers in their old ages and to protect elderly against the risk of poverty. As Pension fund system is a cornerstone of countries economy, policymakers across the globe are still discussing about universal effective pension fund systems and struggling to implement and fit it to the country’s economy demography and financial system. From this point the main objective of this research topic was to test the effectiveness of new pension system reform in Georgia. It focuses on whether the reform will have positive effects on tackling poverty among elderly and bring to Georgian people real prosperity. Despite of the central government announcement that the new system of accumulative pension was successfully adopted in the country, there are still hot debates and discussions in Georgian society including its fairness and effectiveness, which indicates the lack their awareness and involvement in this process.Since workers aged over 40 can opt-out from the pension system, hundreds of thousands among population will remain without a decent pension in the future. This will cause massive poverty in old age. The main aim of this paper is to analyze exciting pension fund reform in order to give people a clear understanding of reform. In the presented research, there is discussed the introduction and development reform of the pension system in Georgia. International experience is also analyzed on the example of other countries, specifically Armenia, Azerbaijan Estonia and Latvia. It also discusses the characteristic aspects of the pension model introduced in Georgia.

Authors: Bibani Herish , A. Alhaleem Ayad , Sharifi Mohammad
Published: March 2023

Heavy oil is classified as unconventional oil resource because of its difficulty to recover in its natural state, difficulties in transport and difficulties in marketing it. Upgrading solution to the heavy oil has positive impact technically and economically specially when it will be a competitive with conventional oils from the marketing prospective. Developing Qaiyarah heavy oil field was neglected in the last five decades, the main reason was due to the low quality of the crude oil resulted in the high viscosity and density of the crude oil in the field which was and still a major challenge putting them on the major stream line of production in Iraq. The low quality of the crude properties led to lower oil prices in the global markets as well as the high operation cost of production and transportation. The purpose of this paper is testing new technology applications on an Iraqi Heavy Oil Field and specifically (Qaiyarah Oil Field) by applying the cold cracking technique to upgrade Qaiyarah heavy oil properties through using series of electrical/ mechanical activities applied on the heavy crude that generates special kind of vibrations to re-structure the (H-C) bonds in the heavy oil to convert it to lighter crude with lower viscosity/ density which was the outcome of the distillation by reducing the unsaturated components and isolating the minerals and sulfur as sold components. The results were very optimistic, where the density has improved from 16 to 30.5 API degree, sulfur content has reduced from 6.4 to 1.507 weight percent and selling price per barrel would increase by 53% compare to 2.31% cost increment due to the upgrading operation. Therefore, applying the cold cracking technology is convenience for improving Qaiyarah oil properties as the main production stream line will be increased in Iraq.

Published: March 2023

in the series of publications, which this article opens, we consider five fundamental neuromorphological observations of our compatriot, the classic of world neuroscience, Volodymr Betz. For four of them, we demonstrate the status of discoveries for the first time, for the other one — the giant pyramidal neurons of the motor cortex — despite its widespread and long-standing recognition, we reveal the limitations of modern knowledge and ideas. Two of the mentioned observations — giant fusiform, or spindle-shaped neurons of the cingulate and insular cortex and islands of the entorhinal cortex — are currently known only to a narrow circle of specialists; to the others two, islands of Calleja and signs of the columnar cortex organization, we pay attention for the first time. In this, the initial part of the series, exposing modern apprehensions about the structure and functions of the entorhinal cortex, we demonstrate the weight of Betz's pioneering observation of extraordinary neuron clusters, which are nowadays known as entorhinal islands, and prove the fact of recognizing his historical priority in the description of these amazing brain structures.

The realistic simulation model of a water distribution network has been widely applied in water resource management, from optimization design to operation management. However, the calibration of the model simulation to adapt with reality is still a challenging task, because within the water distribution network, there are numerous unknown variables, such as: variant consumptions, pipeline characteristics, losses and uncontrollable or non-revenue water, especially flows at potential leak points. This study presents the simulation and calibration of the hydraulic model of the water distribution network in the Northern area of Ho Chi Minh City, including Go Vap District and a part of District 12. The network currently supplies water for more than 140.000 water meters and the water flow into and out of the network in real time is controlled in the study area. The results of the calibration of the water distribution network model are assessed to be consistent with the actual operation in terms of flow and water pressure changes during the day at the observation points by performance metrics. On that basis, the study continues to apply the calibrated model to analyze the water source tracing to determine the interference areas between two water sources in the study area from two water treatment plants.

This is an experimental study to determine that the minimum fluidization velocity, the fluidized bed height, and the pressure loss through the grain layer depend on the thickness of grain layers and moisture content of materials. The drying materials used in this study are fresh pepper and dried pepper of which moisture content is 54.2% and 12%, respectively. All the experiments are conducted with the thickness of the pepper layer ranging from 4mm to 44mm while the wind speed ranging from 5 m/s to 11m/s. From the result of experimental analysis, it can be seen that the minimum fluidization velocity of an air stream through fresh pepper ranges from 5.2m/s to 6,5m/s. The pressure drop of air stream through the fresh pepper is 225Pa while 147Pa for dry pepper, corresponding to the grain thickness of 37mm layer. By comparing the results determined from these experiments with computational models and some available correlations, the computational models of Fedorov, Baeyens-Geldart and Leva all match the experimental data collected from the pepper material. The correlation between the calculated and experimental results has a negligible error, the tendency to increase pressure loss depends on the thickness of grain layer is also quite similar. From the experimental data results obtained by determining the pressure drop through the pepper layers which depends on the thickness of both fresh pepper and dried pepper, the linear equations of the first order are established with high credibility.

This paper presents a new pulse width modulation (PWM) technique in order to eliminate common mode voltage for a single-phase full H-bridge T-NPC inverter. Three-level NPC inverters are commonly used in grid connected applications or as UPS backup power for industry. In addition to abilities such as to withstand high voltage, and reach output voltage and current with low harmonic distortion, three-level NPC inverter is advantageous for mitigating common mode voltage and leakage current. The new proposed PWM technique is based on the switching state table of the three-level H-bridge T-NPC inverter that containing many switching states with zero common mode voltage. Furthermore, implementation of PWM control for single-phase three-level T-NPC inverter configuration can decrease voltage stress on the output and reduce output voltage distortion compared with bipolar PWM control technique for two-level H-bridge inverter. In this paper, the sine wave carrier PWM technique is analyzed, designed and modelled based on the switching table. The analytical analysis will be evaluated using MATLAB/SIMULINK. Simulation results of the proposed PWM technique for three-level T-NPC inverter are compared with conventional techniques without common mode voltage elimination; the quality of the three-level T-NPC inverter is also compared to that of traditional two-level inverter. The power loss content is evaluated using PLECS software. The obtained results confirm the advantages of the eliminated common mode voltage PWM technique in the three-level T-NPC inverter configuration.

Mineral scale deposition (especially CaCO3) is a severe problem at many oil fields, in which the scale adheres to the inner surface of the production tubing and the pre-processing facilities causing significant reduction of flow rate and damage the production system. Recently, many researches have been conducted by oil and gas company in Vietnam to study this subject based on production data and experimental results using commercial software for example ScaleChem and ScaleSoftPitzer. The previous mentioned commercial software only uses thermodynamics approach without consider the effect of fluid dynamics and chemical reaction kinetics. Moreover, there is still a lack of intensive researches on the physical and chemical phenomena associated with CaCO3 mineral scale deposition. This paper presents the construction of an integrated model in which the mechanism of mineral scale deposition is fully characterized by not only thermodynamics but also fluid dynamics and chemical reaction kinetics. The developed model can be used to build CaCO3 scaling profile for oil and gas production wells.

Introduction. Adolescence period requires special supervision as these years link the impact of generational and early childhood factors to adult outcomes. The World Health Organization (WHO) defines 10-19 years as adolescence period, an important stage of growth and development in the lifespan of an individual. The present study assessed nutritional status among adolescents of two villages of Purba Medinipur, West Bengal, India. Materials and Methods. A cross-sectional study of 443 (208 boys; 235 girls) rural high school students aged 10–15 years of Ajaya and Deulpota villages, Khejuri- I block, Purba Medinipur district, West Bengal, India, was undertaken to evaluate their growth pattern and nutritional status. Anthropometric measurements, including height (cm), weight (kg), mid-upper arm circumference (cm), were measured following standard techniques. Stunting, underweight and thinness were used as indicators of nutritional status. Results. The overall prevalence of stunting, underweight and thinness were 20.32%, 1.81% and 46.95%, respectively. The prevalence of stunting was similar in both sexes (20.67% in boys; 20.0% in girls). The prevalence of thinness was very high among the studied participants (46.63% in boys; 47.23% in girls). According to the WHO classification for assessing severity of malnutrition, the rate of stunting and underweight were medium and low in both sexes, respectively. However, they had very high prevalence of thinness thus indicating a critical situation of undernutrition. Conclusion. The nutritional status of these rural school going adolescents was not satisfactory. The existing prevalence of stunting and thinness among the studied population indicates chronic nutritional deficiency while the low prevalence of underweight reflects that the chronic food deprivation they have undergone was during childhood, not in recent period. Follow up studies and intervention of government schemes are required to ameliorate this problem.

Der Verjährungseinredeverzicht ist in der Praxis ein äusserst wichtiges Mittel des Verjährungsmanagements. Der Schuldner erklärt einen Verjährungseinredeverzicht in der Regel dann, wenn der Gläubiger aufgrund des bevorstehenden Verjährungseintritts damit droht, den behaupteten Anspruch mit einer Betreibung oder Klage durchzusetzen. Ein Verjährungseinredeverzicht verschafft den Parteien Zeit, einvernehmlich eine aussergerichtliche Einigung anzustreben, ohne dass diese durch den drohenden Verjährungseintritt erschwert wird. Das schweizerische Privatrecht hat seit dem 1.Januar 2020 ein neues Verjährungsrecht mitsamt einem revidierten Art. 141 OR über den Verjährungseinredeverzicht. Die Revision von Art. 141 OR bringt verschiedene Neuerungen mit sich. In vielen Punkten hielt der Gesetzgeber aber auch an der Rechtslage unter dem vor der Revision geltenden Recht fest. Ziel der vorliegenden Dissertation ist es, die revidierte Bestimmung über den Verjährungseinredeverzicht in seiner Gesamtheit zu erfassen und Unklarheiten zu beseitigen. Dabei ist der Autor bemüht, dogmatisch vertretbare und gleichzeitig für die Praxis taugliche Lösungen aufzuzeigen.

In the article, this method is adapted to construction practice: the coefficient of reflected radiation from the adjacent horizontal site of the studied building to an elementary section of the facade is calculated. Using this method, calculations were made for the component of solar radiation reflected from the underlying surface onto an elementary section of the facade for 12 months. The results are analyzed. The necessity of taking into account the dimensions of a horizontal platform adjacent to an arbitrarily located building and the location of the receiving area on the facade under study for the receipt of the reflected component of solar radiation from the underlying surface is shown.
SELECTION AND JUSTIFICATION OF THE DESIGN OF A BLOW-DOWN DOOR FOR A HOUSEHOLD OVEN
Authors: Shevyakov Vladimir
Published: March 2023

Various designs of blow-down doors for household stoves are considered. The result of the analysis of the existing blow-down doors showed that such designs do not allow to qualitatively regulate the flow of air into the furnace under different gorenje modes for different firewood stoves, which reduces the possibility of increasing efficiency and reducing CO emissions in the furnace. The design of a blow-down door with one entrance opening blocked by a curtain is proposed. A study of such a design with different-shaped inlet openings showed that a door with a triangular-shaped opening allows the most rational adjustment of the air flow into the furnace with a curtain, which improves the characteristics of the furnace.

The article is devoted to the synthesis of a chemically modified version of one of the most important additives for the prevention of low-temperature precipitation in engine oils - polyalkenyl succinimide. This additive is prepared by alkylating maleic anhydride with an α-olefin oligomer and then reacting the resulting oligoalkenyl succinic anhydride with various amines. A new compound, an oligomer of hexene-1 with dicyclopentadiene, was used as an alkylating agent, which makes it possible to expand the raw material reserves of oligomeric compounds used in the synthesis of polymer additives, as well as to impart anticorrosive properties to the additive by introducing dicyclopentadiene rings. The composition and structure of the obtained compounds were studied by appropriate physicochemical research methods. The content of 1.5% of the obtained additive in M-11 oil completely eliminates oil corrosion and improves detergent properties. And this allows you to create a lubricant composition with a simpler composition and, as a result, gives an economic effect. The sample of the new additive complies with the requirements for the industrially produced C-5A additive and, in addition to an increased oil viscosity index; it also has anti-corrosion properties, which is due to the chemical structure of the raw material, i.e., the presence of a carbocyclic dicyclopentadiene fragment in the molecule

The platinum nanocomposites were synthesized by chemical reduction of H2PtCl6·6H2O in situ with a methanol—water mixture using mesoporous graphitic carbon nitride as a stabilizing matrix and a catalyst support. The textural, morphological, and optical properties of the obtained platinum – mesoporous carbon nitride composites (Pt/mpg-C3N4) were studied. Pt/mpg-C3N4 has been developed as an effective heterogeneous catalyst for the gas and liquid phase hydrogenation of phenylacetylene. An efficient and versatile approach to the modification of platinum with various organic solvents and ligands for the selective hydrogenation of phenylacetylene to styrene in a flow gas-phase process is pre-sented. The addition of pyridine, piperidine, or morpholine to the starting solution of phenylacetylene in hexane provides 95–100% conversion and 90–92% selectivity to styrene. A sharp increase in the selectivity to styrene without substantial changes in conversion is also observed when THF, ethanol, triethylamine, dioxane, or chloroform are used as diluents. The obtained Pt/mpg-C3N4 composites also demonstrated considerable catalytic activity in the selective hydrogenation of phenylacetylene to styrene at low temperatures in the liquid phase

Alunite ore containing a significant amount of aluminum, iron oxide, titanium dioxide, and other valuable components (Ga – 0.003 wt%, V – 0.0315 wt.%) is the main raw material for the production of alumina and promising raw material for the production of gallium and vanadium. This paper studies the dynamics of the distribution of gallium and vanadium in the liquid phase during the dissolution of raw alunite in an alkaline solution are studied. The results have showed that alkali concentration, leaching temperature, liquid-to-solid ratio have a significant effect on the degree of extraction of these elements from solution. It has been found that when raw alunite ore is leached with a 5% NaOH solution (S:L=1:6) for 2 hours, the degree of extraction of Ga and V is, respectively, 50.2 and 59.23% of their total content in the rock

Стаття присвячена актуальному питанню сучасності – створенню нових організацій часу і форми праці, які є гнучкими формами зайнятості, орієнтованими насамперед на продуктивність і повне використання потенціалу працівника. Проаналізовано різноманітні форми гнучкої зайнятості. Досліджено світовий досвід організації часу і форм праці. Виявлено, що завдяки розвитку ІКТ (інформаційно-комунікаційних технологій) і доступу до Інтернет, змінюється модель роботи шляхом впровадження дистанційної роботи, що виступає трендом сучасного менеджменту праці, системи розподілу завдань і віддаленого обліку робочого часу. Така модель праці особливо важлива в ІТ-сфері і створює можливості працевлаштування спеціалістів незалежно від місця їх проживання. Однак, щоб організація функціонувала належним чином відповідно до моделі, має бути виконано ряд технічних умов, необхідних для виконання роботи та спілкування в компанії, а також формальних умов, пов’язаних, серед іншого, з формою працевлаштування. Окреслено перспективи майбутніх досліджень.

Four body-size and fourteen head-size measurements were taken from each Chinese alligator (Alligator sinensis) according to the measurements adapted from Verdade. Regression equations between body-size and head-size variables were presented to predict body size from head dimension. The coefficients of determination of captive animals concerning body- and head-size variables can be considered extremely high, which means most of the head-size variables studied can be useful for predicting body length. The result of multivariate allometric analysis indicated that the head elongates as in most other species of crocodilians. The allometric coefficients of snout length (SL) and lower ramus (LM) were greater than those of other variables of head, which was considered to be possibly correlated to fights and prey. On the contrary, allometric coefficients for the variables of obita (OW, OL) and postorbital cranial roof (LCR), were lower than those of other variables.
Impacts of endangered Key deer hervivory on imperiled pine rocklands: a conservation dilemma?

In the lower Florida Keys, endangered Key deer (Odocoileus virginianus clavium) herbivory, along with fire, can affect pine rocklands, an endangered plant community. We compared pineland vegetation from three studies over approximately 50 years on four islands with either high or low deer density (historical analysis). We also compared extant vegetation samples between two islands with high or low deer density, which contained pinelands burned 10 years and 14 years prior to sampling and control areas (unburned for > 50yr). In addition, experimental deer exclosures and control plots established in pineland were prescribe burned and analyzed for deer effects on an island with high density of Key deer. The historical analysis suggests that, over time, deer-preferred plant species declined while less-preferred species increased, regardless of fire history on islands. The extant vegetation analysis suggests that fire and Key deer herbivory both reduce hardwood plant density and growth. Densities of deer-preferred woody species were higher on an island with low deer density than on an island with high deer density in burn treatments, but relatively similar in control areas. On the high deer density island, a fire effect was evident in that the control area had higher densities of woody species than burned areas, and herbaceous species richness was higher in the control area, indicating a possible refuge from deer herbivory. In deer exclosures, preferred woody species and herbaceous species tended to increase after fire, but decrease in adjacent open plots. Results suggest that Key deer herbivory, along with fire, shapes pine rockland plant communities, and that overbrowsing might have substantial impacts on preferred herbaceous and woody species in pinelands. Therefore, efforts could be confounded in managing both the endangered Key deer and the endangered pine rocklands that they affect.

Objective: To photodegrade Diuron with TiO2-Al2O3 nanomaterials supported on graphene nanoplatelets (GnPs)
Design/methodology/approach: The synthesis of the materials was carried out by the sol-gel method under mild conditions. Subsequently, the obtained materials were subjected to thermal processing for structural stabilization and pulverized. Synthesized nanomaterials were then characterized by nitrogen adsorption/desorption, X-ray diffraction, scanning electron microscopy, and Uv-Vis spectroscopy.
Results: The adsorption/desorption results indicated that the ternary TiO2-Al2O3/GnPs nanomaterials were found to have complex porosity, which suggested that TiO2-Al2O3 was formed on agglomerated GnPs. X-ray diffraction data revealed that the anatase phase of TiO2 and the g-Al2O3 phase coexist with the crystalline phase of graphene. The morphology of the materials indicates that the nanoplatelets were randomly dispersed in a continuous mixed oxide phase. About the UV analysis, the presence of GnPs at 1 wt % concentration reduces the band gap by 6%.
Limitations on study/implications: The physical and chemical properties of GnPs make the material an excellent candidate for the degradation of pollutants by photocatalysis.
Findings/conclusions: The addition of GnPs improved the Diuron degradation, probably by forming a nanostructured interface or heterojunction.
