Generally, wood vinegar (WV) is produced from one-step carbonization for all purposes, i.e., antibacterial, food preservative, and agriculture. This carbonization process will result in WV with high phenol content. High phenol is beneficial for antimicrobials but can cause damage to plants if the WV concentration is not suitable. This research aimed to examine the effects of pyrolysis temperature stratification on three other biomass pyrolysis. This study uses hardwood, softwood, and nonwood waste, which are pyrolyzed with temperature stratification, namely 200, 300, 400, and 500 oC. Proximates of raw material, pH, specific gravity, acetic acid, phenol, FTIR, and GCMS were used to characterize the physicochemical properties of the WV. The results showed that the pyrolysis temperature stratification affected the physicochemical of WV. The lowest acetic acid and phenol primarily obtained at a temperature of 200 oC, found in teak wood vinegar (TWV), followed by bamboo (BWV) and pine wood (PWV), i.e., 1.92%, 4.9%, 8.02% (acetic acid) 0.1%, 0.2%, and 0.52% (phenol) respectively. In general, liquid smoke at 200 oC is dominated by 2-methoxy phenol (in TWV & PWV), but at BWV, it is dominated by 2,6-Dimethoxyphenol. There were four dominant groups of compounds, namely acids, phenols, lactones, and carbonyls.

In pursuit of a biodynamically potent molecule, we have attempted to synthesize derivatives of piperazine by incorporating them into the Rosuvastatin intermediate. The reason behind this is that heterocyclic compounds with nitrogen atoms in their ring structure, such as pyrimidine, have great potential as drug design scaffolds. By doping piperazine into the Rosuvastatin intermediate, a series of new derivatives made up of aryl-amides, acetamides, and sulfonamides were produced. These derivatives were then assessed for their antimicrobial activity, with a few showing promising results.

Pyrazinamide (PZA) is one of the anti-tuberculosis (TB) drugs that have an action on the pncA gene encoding the PZase enzyme. Mycobacterium tuberculosis clinical isolates R14 and R7 showed PZA resistance up to doses 40 and 30 µg/mL, however, the basis of their resistance was unknown. The pncA gene of them was cloned into a pGemT vector, then characterized by sequencing. The pncA measuring 0.6 kb has been inserted into pGemT to form recombinant DNA at 3,6 kb. The pncA nucleotides of R14 and R7 showed four and two mutations toward the PZAsensitive isolate H37RV. The mutations of G76T; G112C; A403C; G426A changed amino acids A26S; A38P; T135P were found in R14, while mutations G115A and T506C which changed A39T and V169A amino acids found in R7. The mutation triggered the decrease of two hydrophobic amino acids in R14 PZase, but one in R7. An additional polar amino acid was also found in R7 PZase. The PZase structure of both mutants changed conformation from the native structure H37RV with RSMD as 0.5 and 0.3 Å. The pncA mutations that followed by the change in protein properties and structures might induce the emergence of PZA resistance in the isolates.

Authors: Kohli Ruchi , Mittal Anu , Mittal Amit
Published: April 2023

The density functional theory calculations have been applied to investigate hydrogen-bonded complexes of nicotinamide with parent uracil and its anticancer derivatives namely 5 fluorouracil and 2 thiouracil. The optimized complexes are analyzed in terms of structural, electronic, and energetic changes, binding free energy and enthalpy changes, dipole moments, atomic charge variation, electron delocalizations, topological parameters, chemical reactivity descriptors, etc. The study suggests that the most stable complexes are formed by nicotinamide with fluorouracil and the least stable with thiouracil. The uracil and its derivatives act as far better hydrogen bond donors than nicotinamide in the optimized complexes. Significant charge transfer between nicotinamide and parent uracil and its derivatives is suggested by Frontier Molecular Orbital (FMO) analysis and E(2) from Natural Bond Orbital analysis. The present computational study shows that uracil drugs form stable intercalation sites with nicotinamide. The results may prove useful in the molecular designing of new anticancer agents.

It is well known that microorganisms are omnipresent. It would be fascinating for scientists to encounter organisms that not only grow in normal conditions but are able to thrive in extreme conditions. Such organisms are suitably termed extremophiles including thermophiles, psychrophiles, alkaliphiles, piezophiles, and marine extremophiles, to name a few. The UN General Assembly has proposed 17 goals with 169 targets to attain sustainable development by 2030 with a motto of health for all. Microorganisms play a vital role in the well-being of not just humans but animals as well as plants. Of the 17 goals, goals 14 and 15 address life in water and life on land and the need for protecting our Biodiversity, both on land and sea. The soil on land is a hub for various microbes, likewise, microorganisms show equal presence in marine habitats, able to survive the extremes of conditions. The ability of these microbes to cope with such extremes of conditions makes them an ideal candidate in search of metabolites that would be suitable candidates for various industrial and pharmaceutical applications. It thus becomes significant to analyze and study extremophiles for their properties that include primary and secondary metabolites obtained from them. Enzymes from these extremophiles, known as extremozymes, could potentially be more stable which is an important aspect for various industrial aspects including pharmaceutical purposes. The present article dwells on extremophiles and the extremozymes obtained from them and how these could play a role towards achieving goals 14 and 15 that ultimately would also cater to goal 3, that being the health and wellbeing of all.

Tamoenju (Hibiscus surattensis L.) is one of the ethnomedicinal plants used in treating hypertension. One of the potential antihypertensive mechanisms includes angiotensin-converting enzyme ACE inhibitors, considered the firstchoice treatment for hypertension. This research presents a physicochemical, phytochemical, and ACE inhibitory activity test of tamoenju leaf extract (TLE). The leaf extract was evaluated to determine the physicochemical and phytochemical profiles using standard methods. The physicochemical evaluation indicated 20.66 ± 3.51% water content, 26.67±5.77% drying shrinkage, 2.0 ± 1.0% total ash value, 0.30 ± 0.13% acid insoluble ash value, 20.00 ± 4.00% water soluble extractive value, 57.00 ± 4.61% alcohol soluble extractive value, and 0.89±0.01 g/ml specific gravity extract. The total plate and yeast mold numbers were 15x103 CFU/g and 92 x 10 CFU/g, respectively. The results of metal contamination showed Pb 1.05 ± 0.15 mg/kg and Cd 0.14 mg/kg. The phytochemical evaluation revealed the presence of tannins (69.02%), flavonoids (27.63%), alkaloids (14.18%), saponins (2.12%), and steroids (1.06%). ACE inhibitory activity was tested and obtained at 38.50±1.41 µg/mL for TLE and 9.44±0.58 µg/mL for captopril. Based on the research results, TLE qualifies as a standardized extract and can be used as a reference for developing herbal medicines. Tamoenju leaves extract is quite high as a natural ACE inhibitor and has the potential as an antihypertensive.

Published: April 2023

The refractive index of liquid crystals at infrared wavelengths is to be measured using a novel technique. This method involves constructing the envelopes for the transmitted intensities using the envelope method on Fourier transform infrared spectral data before doing refractive index measurements. The upper and lower envelopes for the envelope approach are made using the transmitted wavenumber intensities. In this case, we consider hydrogenbonded mesogens, specifically p-n-alkyl benzoic acid : p-(p'-Octyloxybenzylidene)-p-cyanoaniline (nBA: OBCA, where n=6, 8). The outcomes of this research demonstrate that the hydrogen-bonded mesogens nBA:OBCA have higher refractive indices than the pure compounds. Refractive index values in the infrared area drop with decreasing wave number and reach saturation. The proposed technique evaluates samples' refractive indices in the infrared region (4000cm-1 - 400cm-1) which is difficult-to-measure. Molecular interactions of hydrogen-bonded liquid crystals are also investigated.

The article is devoted to the issues of forming a security-oriented information environment in Ukraine. In the context of increasing influence of internal and external destabilizing factors, realization of unprecedented threats to all components of national security caused by the military aggression of the Russian Federation, ensuring the formation of a security-oriented information environment is the basis for the realization of national interests, which creates new opportunities for strengthening the security of the national economy. The methodological content of the concepts of scientific approaches to ensuring the security of the national economy is investigated. It is proved that the information security of Ukraine’s economy is a complex, non-equilibrium, non-linear, self-organizing system, which justifies the use of a synergistic approach in its research. The concepts of forming a security-oriented information environment substantiated in the study are based on the provisions of a new paradigm of using the opportunities associated with the development of information technology and preventing and countering new threats to information security by protecting information, ensuring the reliability, integrity and availability of public information resources, restricted information, in particular, the one circulating in the economic information infrastructure facilities and determining the further secure development of the state by creating a security system for computer systems for economic data processing (CSEDP) and taking into account external and internal threats realized as a result of the military aggression of the russian federation. The authors have developed a model for the formation of a security-oriented information environment in Ukraine aimed at protecting national economic interests and ensuring the security of the national economy. These key conceptual provisions should serve as a theoretical basis for further development of the methodology for ensuring information security of the national economy.

Published: April 2023

The effectiveness of management decisions largely depends on timely receipt of information about economic operations. The main source of such information is accounting. A properly organized income accounting system has a significant impact on the strategic success of business entities, since the formation of the financial result of the enterprise and its further functioning in the long term depends on it. The purpose of the article is to study the essence of the accounting and economic category “income” and determine the place of income in the accounting and management system at an industrial enterprise. The article highlights the views of scientists regarding the economic meaning of the concept of “income”. An analysis of the definition of “income” in regulatory, accounting and economic sources was carried out, on the basis of which it was established that the accounting approach to the essence of income is based on the term “economic benefit”. Highlighting a unified approach to the essence of income allows you to emphasize the importance of this category for accounting and forming reporting indicators. The results of the conducted research showed that the lion’s share of income falls on income from operational activities, thereby emphasizing their importance in industrial enterprises. For effective management of operating income, it is important to have a high-quality classification of them. A meaningful classification of operating income plays a leading role in the accounting and management system at an industrial enterprise. The classification system should be flexible and quickly adapt to the needs of information users in order to make effective management decisions. However, industrial enterprises have significant features of their activities, therefore, when classifying income, the specifics of various branches of the industrial sector must be taken into account.

In the study, attention is updated to the problem of stimulating the development of small entrepreneurship at the local level and simultaneously improving the system of providing social services to the local population, in particular medical care. It was emphasized that stimulating the development of small business entities and also the medical sector in rural and remote areas is a very difficult task that requires identification in the implementation of specific tools and the involvement of sufficient resources for such purposes. It has been proven that this is why research in this field is always unique and has a high theoretical, methodological and applied value. The purpose of the study is to improve the theoretical, methodological and applied principles of forming policy tools for supporting and stimulating the development of small entrepreneurship in the medical field at the local level. It is shown that the decentralization reform, which is being implemented with permanent success in Ukraine, has largely shifted from the central to the local level the issue of management and financial and resource provision of local social and economic development. These issues become particularly acute in the field of medicine, and often local self-government bodies are objectively unable to solve these extremely difficult tasks on their own. It is necessary to use non-traditional methods and approaches. One of these can be the stimulation of private business in the form of small private health care institutions that provide a wide range of diagnostic and preventive medical services to the population. It was concluded that the policy of local self-government bodies in terms of promoting the development of small business initiatives in the field of providing medical services to the population should be broad in nature, in particular aimed at the general socio-economic development of small towns and surrounding rural areas. Conceptually, the principles of such a policy can be implemented in the following directions: development of production factors; creation and improvement of small business support infrastructure; formation of solvent demand due to increased employment and incomes of the population; development of priority sectors of the economy; increasing the efficiency of small enterprises in the medical field.
Use of clay-containing waste as pozzolanic additives
Authors: Gerasimov Andrei , Ustinov Ivan , Zyryanova Olga
Published: April 2023

Growing productivity of mining and processing enterprises entails an increase in the volumes of liquid tailings impoundments and upstream impoundments of ore processing waste. Enterprises face the challenge of minimizing the environmental impact of waste and guaranteeing the sanitary and epidemiological safety of population. The article presents a possibility of recycling one type of such waste (clay-containing concentration tailings of apatite-nepheline and sylvinite ores, coal beneficiation tailings) by using them after preliminary thermochemical treatment as pozzolanic additives to cements and concretes, including concrete mixtures used for soil stabilization, development of territories, reclamation of mine workings, as a component of the insulating layer of landfills for the disposal of municipal solid waste. An analysis of the phase changes of kaolinite, one of the main minerals that make up clay-containing waste, in the temperature range of 200-1,000 °С showed that a change in its mineral form during heat treatment is the main factor in changing its pozzolanic activity. The effect of heat treatment of clay minerals at temperature of 700-800 °C on their pozzolanic activity, estimated by the ability to absorb calcium hydroxide (0.7 g Ca(OH)2 per 1 g of modified kaolinite), is considered. It is shown that the addition of heat-treated samples (20 % by weight) improves the quality of cement increasing its activity by 15 %, in comparison with the use of unmodified clay minerals. It was proved experimentally that partial replacement of Portland cement with thermally modified kaolinite increases the strength of consolidating stowing mixture by up to 15 %. This approach to processing of ores containing layered silicates, which provides for thermochemical modification of run-of-mine ore, intensifies the processes of tailings thickening and filtering.

This article is a review of the mechanical properties of fiber-reinforced concrete at high strain rates under tensile and compressive stresses. Fibre-reinforced concrete is widely used in the construction of protective structures, in tunnels, engineering structures in seismic areas, airport runways, river and marine engineering structures and is an important substitute for classic concrete.
The review covers the following aspects: advantages and disadvantages of various test methods used to determine the dynamic properties of fiber-reinforced concrete; studies of the dynamic characteristics of fiber-reinforced concrete in compression and tension, including their strength, deformation capacity and ability to absorb energy. The purpose of this review is to expand fundamental knowledge about the dynamic properties of fiber-reinforced concrete and to promote further research on its physical and mechanical characteristics and applications for increasing the strength of brittle materials.
At the beginning of the review, the most commonly used test setups and methods for dynamic testing are considered. The Kolsky method is most widely used to determine properties in dynamic compression, tension, and tensile splitting at high strain rates. Further, the main part of the review considers the mechanical properties of fiber-reinforced concrete under dynamic compression and tension, including strength, impact strength, and the ability to absorb energy. Studies have shown that with an increase in the rate of deformation, the dynamic strength of fiber-reinforced concrete increases. The use of an appropriate amount of fiber leads to a significant improvement in dynamic properties. However, there is a threshold fiber content. In conclusion, by summarizing and comparing previous studies, the advantages and disadvantages of existing studies are emphasized, and suggestions for further research are made.
MODELING OF THERMO-ELASTIC-VISCO-PLASTIC DEFORMATION OF SHALLOW METAL-COMPOSITE SHELLS USING THE REFINED THEORY OF BENDING
Authors: Yankovskii A.P.
Published: April 2023

The dynamic problem of thermo-elastic-viscous-plastic deformation of shallow composite shells is formulated using the refined theory of bending. In this case, tangential displacements along the thickness of constructions are approximated by polynomials of the third and higher orders, and the deflection does not depend on the transverse coordinate. Normal transverse stresses in the composition have a linear distribution over the thickness. The temperature over the thickness of the curved panels is approximated by a 7th order polynomial. The geometric nonlinearity of the problem is taken into account in the Karman approximation. The constructions are multidirectionally reinforced with continuous fibres. The composition materials are isotropic; their plastic deformation is described by the flow theory with isotropic hardening, and the loading function depends on temperature and strain rate. The numerical solution of the coupled nonlinear two-dimensional initial-boundary value problem is obtained using an explicit scheme. Elastic-viscous-plastic, thermo-elastic-plastic and thermo-elastic-viscous-plastic response of a metal-composite cylindrical shallow shell of a rectangular shape with an orthogonal 2D-reinforcement structure has been studied. The construction is frontally loaded with an air blast wave. It has been demonstrated that curved metal-composite panels under such loading must be calculated, taking into account the temperature response that occurs in them and the sensitivity of the plastic properties of the composite materials to the rate of their deformation. In this case, it is necessary to apply the refined theory of bending of shallow shells, and not its simplest version, the Ambartsumian theory. A more intense thermomechanical response of a curved panel is observed when it is dynamically loaded from the convex front surface. In this case, at individual points of the construction, the temperature can briefly increase by 200 °C. It has been found that under dynamic loading of shallow shells from the side of any face-surface, they snapping towards the concavity of thin-walled structures.

Penyakit ini menjadi sorotan karena kemunculannya di akhir taun 2019 pertama kali di wuhan, china. Penyebab corona virus merupakan virus single stranded RNA yang berasal dari kelompok corona viridae. Dinamakan corona virus karena permukaannya yang berbentuk seperti mahkota. Virus lain yang termasuk dalam kelompok yang serupa adalah virus yang menyebabkan Middle East Respiratory Syndrome (MERS-Cov) dan Severe Acute Respiratory Syndrome (SARS-Cov) beberapa tahun silam. Namun virus corona wuhan ini merupakan virus baru yang belum pernah teridentifikasi pada manusia sebelumnya. Karena itu, virus ini juga disebut sebagai 2019 Novel Corona Virus atau Covid-19. Salah satu hal yang dapat mencegah penyebaran Virus Covid-19 ini adalah dengan melakukan penanganan Virus Covid-19. Sebagai upaya penanganan Covid-19 di tingkat mikro Satuan Tugas (Satgas) Covid-19 melalui Surat Edaran nomor 9 tahun 2021 memaparkan tentang langkah dan unsur pembentukan Posko Covid-19 Desa/Kelurahan. Posko Covid-19 Desa/Kelurahan sendiri adalah tempat dan perangkat pelaksana sebagai pusat perencanaan, koordinasi, pengendalian dan evaluasi kegiatan penanganan Covid-19 di suatu wilayah desa/kelurahan melalui fungsi pencegahan, fungsi penanganan, fungsi pembinaan, dan fungsi pendukung. Pembentukan Posko Covid-19 di Desa Kalimporo dilakukan berdasarkan inisiatif kepala desa Kalimporo. Maka dari itu, kami dari mahasiswa KKN PPL-Reguler Angkatan XXII Universitas Negeri Makassar, turut membantu dalam pembuatan posko penanganan Covid-19 di Desa Kalimporo Kecamatan Bangkala Kabupaten Jeneponto.

The inverse problem of reconstructing the vertical profiles of CO2 in the atmo- sphere by IR–spectra of the solar light transmission is investigated. To solve this problem, we propose the two-stage method. On the first stage, we use the modified Tikhonov method. On the second stage, to approximate a solution of the regularized equation, we apply the modified Gauss–Newton method. The convergence theorem is formulated and the numerical results for a few of measured spectra are presented.

The article describes an algorithm for constructing unstructured triangulation mesh using the advanced front method. The method of correcting errors of intersection of edges, which usually occurs while constructing triangular mesh, is presented. The errors and their correction are demonstrated in the form of diagrams. Also, in order to compare the parameters at certain nodes before and after changing the boundary of the elastic domain, the article considers the possibility of constructing an additional mesh when a certain part of the boundary of the domain changes in the direction of increase, while the original mesh in the remaining parts of the domain is not changed. The article contains the results of triangulation of certain examples in the form of diagrams. Taking into account that the triangulation code by the method of advanced front was not found in the open access, the approximate code of triangulation including the above methods was written in the Python programming language and posted on the Internet (the link is provided). The article includes a general description of the code. The matplotlib package was used to visualize the results.

We consider a mathematical model which describes the dynamic process of con- tact between a piezoelectric body and two obstacles. The behavior of the material is modeled with a nonlinear electro-viscoelastic constitutive with law long memory and damage. The mechanical damage of the material, caused by excessive stess or strains, is described by a damage function whose evolution is modeled by an inclusion of parabolic type. The contact is modeled with adhesion and wear. The adhesion field, whose evolution is described by a first order differential equation. The evolution of the wear function is described with Ar- chard’s law. For the variational formulation of the contact problem, we present and prove the existence of a unique weak solution to the problem. The proof is based on arguments of time dependent variational inequalities, parabolic inequalities, differential equations and fixed point arguments.

Salinity stress is a form of abiotic stress that threatens the sustainability of agriculture in almost all countries in the world. It has an impact in reducing plant productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable crop that has high nutritional value, but extensive saline land area can cause red amaranth yields to decline. Osmopriming is a seed priming method in which seeds are immersed in a solution that has a high osmotic potential, such as PEG (polyethylene glycol) in order to increase germination under unfavorable conditions. This study determined the effect of osmopriming on germination, physiological, and root anatomical attributes of red amaranth roots under salinity stress conditions. The research design used a completely randomized design with two types of treatment, namely, osmopriming and salinity stress. Each treatment used three concentrations, seed osmopriming with 0%, 5%, and 10% of PEG and salinity stress of 0 mM, 50 mM, and 100 mM of NaCl. The measured parameters were germination, growth, physiological, and root anatomical characters. Osmopriming of seeds with 10% PEG increased germination as indicated by the germination percentage, time, and rate reaching 95.55%, 1.393 day, and 71.98%/day, respectively. Red amaranth plants that had been osmoprimed with 10% PEG grew faster when exposed to salinity stress. Application of PEG 5% and 10% increased total chlorophyll levels while decreasing proline levels and Ca-oxalate crystal density. Under salinity stress conditions, PEG application improved the root anatomical characters of red amaranth as shown by increased epidermis thickness, cortex thickness, and stele diameter. Priming application with 10% PEG has the potential to increase the tolerance of red amaranth to salinity stress.

Background: Microplastics (MPs) and microrubbers (MRs) are a substantial source of pollutants entering the environment and a cause for debate in environmental studies in soils surrounding two landfills and a municipal solid waste transfer station near Ahvaz Metropolis. Since the current information about these particles in Iranian municipal solid waste transfer station and landfill systems is scanty, this study aimed to determine the amounts and abundance of MPs and MRs in soils. Methods: Each of the twelve sites that determined using a systematic grid sampling method had approximately 100 g of soil samples from a depth of 0-10 cm with three replications. The method used for extracting MPs from the soil samples was density separation with saturated zinc chloride solution. The particles were investigated by the size, shape, abundance and colour. A total of 1807 MP and 1872.7 MR particles were detected from the samples. The Pearson’s correlation coefficient (r) was used for describing correlations. Results: The highest abundance of MPs was observed at the S5 site (325.9±26.8 items/100 g soil). The particles were categorized into fragments, foams, fibers, films and spheres. Five ranges of particle size were identified (between 1 mm ≤L and L≤100 μm) in nine color categories. The 1 mm ≤L size class was dominant in MPs (54%) and MRs (52%). The majority of the MPs (41.8%) were white/transparent, whereas MRs were identified as black/gray (99.1%). Conclusion: Contamination by MPs and MRs exceeded allowable standards, compared to other transfer stations across the globe.
