The necessary and sufficient conditions for retirement funding adequacy: A fuzzy set analysis
Authors: Zeka Bomikazi , Veri Francesco
Published: April 2022

Although retirement funding adequacy literature has explored perceptions of retirement preparations and savings targets, there remains a lack of understanding of which conditions are necessary and sufficient for it to occur. This study identifies the necessary and sufficient conditions for retirement funding adequacy by examining the extent to which demographic, psychological and behavioural variables predict its occurrence. Within the context of South Africa, fuzzy set qualitative comparative analysis was used to test a complex model and qualify the processes that lead to retirement funding adequacy. The results show that educated women of higher socio-economic status are associated with retirement provisions. Thus, the inclusion and empowerment of women in financial planning activities results in positive retirement outcomes. Furthermore, retirement provisions precede retirement funding adequacy, and financial knowledge is a necessary condition for both retirement provisions and retirement funding adequacy. This research is relevant for financial planners and institutions encouraging individuals to plan and save for retirement in order to reduce the retirement funding adequacy gap experienced by retirees.
System for maintaining effective axial load on the bit when drilling wells
Authors: Mikheev Sergey A.
Published: April 2022

The destruction of rock at the bottom by mechanical means is impossible without creating an axial load on the chisel. The efficiency of the entire process depends on the correct choice of the value and control of this parameter. Control of the axial load on the rock-breaking tool is one of the main methods of controlling the process of rock destruction in any drilling method. In this regard, a device for automating the search for an effective axial load on the bit is proposed, which allows reducing the time to find the optimal values. The operation of the device is based on the method of a braked drum. Its essence is to find the values of the tool weight corresponding to the maximum of the dPoс/dt function, i.e. the maximum of the mechanical drilling speed. The block diagram of the device and the functional diagram of the computing unit are presented. The time diagrams of fluctuations of the axial load on the chisel and the appearance of signals at the outputs of the device blocks are given.
Analysis of existing types of protection against single-phase earth faults and their application conditions
Authors: Andreev Anton A.
Published: April 2022

Currently, the problem of determining a single-phase earth fault in networks with isolated and compensated neutral mode is still relevant. According to the existing data, according to the time of elimination of these technological violations, the conclusion arises, according to which the effectiveness of existing protections is called into question. This issue is particularly acute for electric grid companies that serve urban electric networks, since the mass of lines laid next to each other and the heterogeneous nature of the load makes the network mode not suitable for the use of modern protections. Therefore, as a definition of damage, the method of sequential disconnection and the method of dividing the network into sections, which were used half a century ago, are used. Therefore, the analysis of the existing earth fault protection will help to identify the existing problem more clearly, as well as set the direction for further scientific research in this area. The methodological basis, in this article, is the analysis. The information for this method is taken from the theoretical and empirical information of previously published works. In particular, the existing types of protection against single-phase earth faults are considered. Their analysis and conditions of applicability for the electric economy of urban electric networks are made. In the course of the analysis, it was found that the existing protection against single-phase earth faults can reduce the search range of OZZ, but, so far, they can not provide absolute selectivity for the conditions of urban electrical networks made by cable lines. Since such electrical networks are typical for densely populated areas, the above problem is relevant and requires a quick solution.

Reviewing the prospects of forest decentralization in Indonesia after the Omnibus Law
Authors: Ramadhan R. , Daulay M.H. , Disyacitta F.
Published: April 2022

In 2020 Indonesia's government passed the Omnibus Law with the objective of creating more jobs and raising foreign and domestic investments by reducing regulatory requirements for businesses. This study examines how the central government is dealing with the administrative and legislative
issues caused by the new law with regard to forest management. Results reveal that while administrative decentralization appears to be occurring, when viewed through the lens of political/democratic decentralization, effective forestry decentralization is not currently taking place due to
a lack of devolvement of effective power to local level representatives.
Global progress towards sustainable forest management: bright spots and challenges
Authors: Shono K. , Jonsson Ö
Published: April 2022

This paper analyses global progress towards sustainable forest management by climatic domains and national income levels using data from the Global Forest Resources Assessment 2020. It also examines enabling conditions for sustainable forest management. The findings reveal progress
towards sustainable forest management globally supported by the widespread presence of enabling frameworks. However, such progress has been uneven, and the rate of forest loss is accelerating in tropical low-income countries where coverage of forest management plans remains low and forest
certification insignificant. Allocating higher proportions of forest areas to conservation and smaller proportions for production in these countries has not led to improved protection and management of forests. To enhance forest management in these priority geographies, this paper proposes
conservation through sustainable use and demonstrates the value of well-managed production forests in maintaining forest cover and ecosystem services at the landscape level.
Predicting Surface Resistivity on Concretes Containing Potential Supplementary Cementitious Materials Cured at Nonelevated and Elevated Temperatures
Authors: Rios Renee T. , Israel Alexandra A. , Kurtis Kimberly E.
Published: April 2022

Time-series surface resistivity (SR) measurements with up to 56 days of hydration on concretes containing potential supplementary cementitious materials (SCMs) cured at an ambient temperature of 23°C and an elevated temperature of 38°C have the potential to indirectly determine the reactivity of many of these SCMs more accurately than conventional indirect testing metrics, such as the strength activity index in ASTM C618, Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for Use in Concrete. SR time-series measurements can distinguish between microstructural densification caused by inert materials and densification caused by pozzolanic materials. However, it may be possible to assess pozzolanicity earlier in the test series, particularly when additional physical and chemical data regarding the material are known. The aim of this paper is to develop predictive models using machine learning on a broad range of both ASTM C618 conforming and nonconforming materials’ time-series SR curves based on the materials’ physical and chemical characteristics and early SR measurement data. Gaussian process regression models were used to predict the SR values of concretes cured at two different temperatures. These models can rapidly screen materials based solely on their chemical and physical characteristics to predict SR curves, which can then be used to determine a material’s suitability for beneficial use in concrete. Models using early age SR measurements were produced to predict the 56-day SR value for concretes cured at both elevated and nonelevated temperatures. This data-driven approach allows for the design of novel reactive materials, the inclusion of existing reactive materials in construction, and a reduction in testing durations.
Mechanical Properties and Microstructural Characteristics of AA5356 Aluminum Alloy Cylindrical Components Made by Wire Arc Additive Manufacturing Process
Authors: Prasanna Nagasai Bellamkonda , Malarvizhi S. , Balasubramanian V.
Published: April 2022

Wire arc additive manufacturing (WAAM) is a high-quality technology for producing large and complicated geometries in close proximity to net shape with low-cost production resources, including welding machines and filler wires. It offers the cost-effective fabrication of large-scale metal parts with high deposition. AA5356 aluminum–magnesium (Al-Mg) alloys can reach medium strength without a solid solution and quenching treatment, thereby avoiding product distortion caused by quenching, which has attracted the attention of WAAM researchers. However, challenges during the additive manufacturing of aluminum alloys, such as porosity or poor mechanical properties, can be overcome by using arc technologies with low heat input. This paper presents metallurgical characteristics and mechanical properties of WAAM AA5356 alloy cylindrical components fabricated by gas metal arc welding (GMAW) and cold metal transferred (CMT) arc welding processes. Herein, a comparison between the welding processes and the resulting heat input shows the effect on the resulting microstructure and the mechanical properties of additively manufactured AA5356 parts. Firstly, the influence of heat input on the porosity and microstructural characteristics were analyzed. Subsequently, the effect of heat input on the mechanical properties of the cylindrical components was studied. The cylindrical component produced by CMT process exhibits fewer and smaller pores with finer grains and reduced segregation of β-(Al3Mg2) phases than the GMAW process. The component fabricated by CMT process showed isotropic superior mechanical properties (tensile properties, hardness, and impact toughness) than the component made by GMAW process.
Análise Criminal como ferramenta de reformulação da Perícia Criminal
Authors: Campos Joara de Paula
Published: April 2022

A perícia criminal precisa de reformulação para ser vista como mais do que uma ferramenta auxiliar aos magistrados no sistema de justiça. A sistematização de seus dados e sua utilização de forma a fortalecer a segurança pública, mais do que a resolução de casos individuais, é o principal caminho para o reconhecimento do seu papel fundamental para toda a sociedade. A análise criminal é uma excelente ferramenta (muito desenvolvida pelos outros órgãos de segurança pública como Polícia Militar e Polícia Civil, mas, ainda, pouco utilizada pela criminalística) para contribuir com a gestão, operacionalização, inteligência e reformulação da perícia criminal. Este trabalho bibliográfico narrativo realizado através de pesquisa em livros, bibliotecas virtuais nacionais e internacionais, e relatórios de órgãos ligados ao governo tem o objetivo de apresentar como a análise criminal pode transformar os resultados dos trabalhos desempenhados pela perícia criminal em ferramentas essenciais não só ao sistema de justiça, mas, também, ferramentas políticas e sociais, o que contribui com uma maior alocação de recursos, popularização do trabalho pericial e sua consequente ascensão na segurança pública. A sistematização de dados sobre vestígios e provenientes da análise pericial com a utilização da análise criminal (administrativa, tática e estratégica) podem contribuir com uma gestão mais eficiente, e com um papel mais ativo nas atividades de segurança pública e inteligência policial, contribuindo com a difusão de seu trabalho para a sociedade.

Published: April 2022

A adipocera (ou saponificação) é o fenômeno transformativo conservador no qual há uma interrupção no processo de decomposição dos tecidos moles, particularmente os mais ricos em lipídios. Apresenta grande interesse para as ciências forenses, pois, por preservar pelo menos parte dos tecidos moles, pode contribuir para o reconhecimento do corpo e para o esclarecimento das circunstâncias e causa da morte. Entretanto, pouca atenção é dada à possibilidade da saponificação contribuir para a identificação necropapiloscópica. Um dos maiores desafios neste tipo de identificação é a obtenção de um registro adequado em corpos que apresentam fenômenos transformativos conservadores, como a adipocera. Mas com a utilização de uma técnica necropapiloscópica adequada é possível obter um registro que permita o confronto papiloscópico. Este relato é de uma vítima de soterramento na qual foi possível a identificação necropapiloscópica após 267 dias de morte por técnica de fervura, com modelagem em Microsil seguida de fotografia digital, onde são discutidos os principais aspectos médico-legais relacionados.

Authors: Cotomacio André Carrara
Published: April 2022

A caracterização da poluição sonora constitui-se um desafio por se tratar de um tipo de evento que deixa vestígios de difícil quantificação e análise, cessando assim que interrompida a atividade da fonte emissora.  Apesar de haver normas que tratam da questão no ordenamento jurídico brasileiro, as medidas adotadas pelo poder público no sentido de caracterização desse tipo de poluição podem não ser tomadas de forma eficaz, principalmente devido à especificidade da norma técnica vigente e às dificuldades em sua interpretação por parte do Perito Criminal. Visando colaborar para uma maior facilitação nesse sentido, o presente trabalho consiste em um relato de experiência a respeito da medição dos níveis de pressão sonora de uma fonte poluidora em uma lanchonete, visando fornecer à autoridade requisitante elementos que possibilitassem a tipificação dos delitos cabíveis. Destarte, foi possível estabelecer os níveis de pressão sonora, conforme o exigido pela norma ABNT NBR 10151:2019, a partir dos procedimentos técnicos necessários para a caracterização de uma sirene como uma fonte emissora de ruído do tipo tonal. No presente relato são discutidos os aspectos e as dificuldades na aplicação da referida norma técnica, bem como as possíveis implicações penais.

Published: April 2022

The article discusses the patterns of distribution and the peculiarities of the formation of gold mineralization in the metamorphic and black shale strata of Azerbaijan  in order to determine metallogenic specialization. Mineragenic analysis of gold-bearing territories was carried out using numerous data of quantitative studies of the substance of the studied objects: ore-bearing sedimentary and metamorphic strata, ore bodies and processes ore genesis. The spatio-temporal relationships of gold-bearing mineralization of various material-morphological types, conditioned by lithological-geochemical conditions and time of manifestation of lithogenetic processes and metamorphism, have been determined. In the petrographic description of the studied rocks, two groups were distinguished: Early Paleozoic crystalline shales and Upper Paleozoic sedimentary rocks. It has been determined that the shales were initially enriched with gold during sedimentogenesis. In subsequent processes of metamorphism, part of the gold was removed from the shale and redeposited, and thus spread unevenly. Favourable zones of ore deposition could lead to the concentration of gold in shales in industrial conditions. In the studied crystalline shales, attention is drawn to the contents of Pt and Pd, the commonest elements of the platinum group. The Pt content in shales is 0.08 g / T on average, while the clarke for clayey shales is 0.03 g / t, i. e. almost three times higher than the clarke. Even more contrasting is the content of the platinum group element, palladium. In shales, the Pd content is 0.046 g / t. These data, together with the high gold content in the shales, can be considered as a typomorphic geochemical feature of the crystalline shales of the Asrikçay massif of the pre-Jurassic basement of the Lesser Caucasus. The studies have shown that during the formation of gold mineralization in metamorphic and black shale strata, an important role was played by the features of the host carbonaceous sedimentary complexes, which served as additional sources of noble and associated metals. Some of the ore elements in unaltered sediments have their own mineral forms.

Published: April 2022

Children’s tourism is one of the widespread types of tourism and performs educational, pedagogic, sanitary and other socially significant functions. It is one of the most steady sectors of the tourist services market. The most developed and oldest segments of children’s tourism in Kazakhstan are health- improvement and cultural-educational tourism, educational programs are consistently in demand. The article is devoted to the development of children’s and youth tourism in the modern social space of Kazakhstan. The article analyzes how children’s and youth tourism is organized in the regions of Kazakhstan, its structure and quantitative parameters. The authors note that both the number of health-improving institutions for children and the consumer structure of children’s and youth recreation have changed: the number of children having a vacation in urban school camps with a day stay, specialized and spa-type camps is gradually increasing. The problem of forming a system of management for children’s and youth tourism lies in the large number of activities with different subordination. The article analyzes the situation with camps in Kazakhstan on the basis of data from the years 2016–2019. We have highlighted the prospects of the regions to develop children’s and youth tourism and the main directions of its improvement. Thereto the market of children’s and youth tourism was studied, the types of recreation that are in the greatest demand were identified. We evaluated the opportunities to develop children’s sightseeing tours in the regions and cities of the Republic of Kazakhstan. To study the needs of children, an opinion poll was held among parents via Google Forms. The polling consisted of 5 questions to which 114 results were received from respondents. In Kazakhstan children’s and youth tourism have a different level of development. The formation and development of children’s tourism depends on many factors: high- quality personnel, a favourable natural environment and the location of historical and cultural heritage, financing, etc. It is understood that the economic growth in the field of children’s tourism in Kazakhstan is kept back by insufficient information transparency, focus on the provision of tourism services, which, in its turn, contradicts the emerging opportunities of communication innovations that have significantly changed the conditions and opportunities to implement processes of interaction between people and elements of socio- economic systems, the high level of inequality of the population’s income requiring the diversification of the tourist product.

The review describes methods of stress corrosion cracking (SCС) tests that implement various conditions for samples loading: at a constant static load or deformation, at a constant or increasing load of samples with a previously grown fatigue crack, with a slow strain rate. Such tests shall be carried out to determine the resistance of shipbuilding materials to be used in loaded ship structures in contact with seawater. Brief descriptions of the mechanism of stress corrosion cracking of steels and alloys are given. The necessity to carry out bench tests of steels and their welded joints, as well as models simulating individual units and elements of structures, is indicated. At this stage, conditions are ensured as close to operating conditions as possible due to exposure in various climatic zones of the world’s oceans (variations in temperature, chloride concentration, amount of dissolved oxygen, degree of biofouling, and their simultaneous impact). It is shown that during verification field tests (final stage) new materials promising for operation in marine conditions pass the final evaluation of corrosion resistance in the form of elements of ship structures and systems in the conditions of ship operation.

A technique was developed for the numerical analysis of the thermal state of long mandrels of a three-roll rolling mill using modern computer simulation software. The initial and boundary conditions were determined taking into account the peculiarities of rolling in a three-roll screw rolling mill on a long mandrel. The authors carried out a qualitative assessment of the thermal state of a long mandrel by means of visualized representation and established its significant inhomogeneity. Influence of the rolling temperature and diameter of the long mandrel were revealed. Small diameter mandrels are heated to higher temperatures (577 °C) with a significantly lower gradient between the axial zone and the surface. An increase in the mandrel diameter to 154 mm lowers the temperature of the outer surface to 530 °C and increases temperature gradient in the near-surface layers up to 18 °C/mm. So the temperature in the near-surface layers for a mandrel of 154 mm at a distance of 10 – 15 mm from the surface decreases from 530 °C to 315 °C. Features of the temperature field in the cross section were established taking into account thermal interaction of the sleeve with the mandrel in the zone of contact with hot metal and in gaps between the rolls. Temperature of the near-surface layers in the contact zone is 30 °C higher than in the gaps. Dependences of temperature of the cross-section characteristic points on the rolling time were determined, it has been established that in the first two seconds there is an intense growth according to the parabolic, and then according to the linear laws. Temperature of the central layers with a radius of 50 mm increases with a much lower intensity, by about 100 °С during the entire period of rolling, while during the same time, the near-surface layers are heated by 300 – 400 °С.

Ferrous metallurgy enterprises continuously fill dumps with steelmaking and blast furnace sludge with high zinc content. Sludge occupying significant territories of enterprises is not involved in production and harms the environment. Since zinc leads to the formation of deposits in the blast furnace, manufacturers cannot involve this sludge in sinter processing. In addition, working with sludge can lead to problems such as decrease in iron content in the sinter, decrease in productivity of sintering machines, and increase in fluctuations in the sinter chemical composition. At the same time, zinc-containing sludge can become a valuable secondary product. Zinc remains a scarce metal, which encourages the development of technologies for processing zinc-containing materials. Extraction of zinc from sludge is difficult because it is not in oxide, but in sulfate or sulfide forms. In this paper, the possibilities of zinc extraction from sludge using the FactSage software package are evaluated. The authors present results of thermodynamic calculations of the possibility of zinc extraction from four types of sludge from two Russian ferrous metallurgical plants – EVRAZ NTMK and MECHEL. The data of chemical and phase analyses of this sludge are considered, as well as simulated graphs of zinc extraction dependencies from them. The graphs were built on basis of the received data from FactSage package. Addition of the reducing agent to the sludge varied, as well as temperature of the process. In addition, the possibility of abandoning carbon as a reducing agent was evaluated. To save the reducing agent, an optimal mixture of the company’s sludge was selected, in which coke consumption can be minimized.

A new approach to obtain amorphous oxides was investigated both theoretically and experimentally using X-ray diffraction (XRD) and electron probe microanalysis (EPMA) techniques. In this work, the conventional sol-gel method was modified by the addition of malic acid as an oxidizing agent and successfully applied to obtain two oxides Al2O3 & Fe2O3 with the amorphous structure. The results of the modified sol-gel method were compared to those obtained by thermal decomposition of corresponding salts, and the advantage of new technique was clearly demonstrated. Thermal stability of the obtained amorphous oxides was examined by the differential scanning calorimetry (DSC). It was found that amorphous Al2O3 is stable up to 790 – 810 °C, while amorphous Fe2O3 recrystallises at about 160 – 180 °C, depending on the heating rate.

The new casting austenitic Cr – Ni – Mn steel with 0.5 % N (grade 05Kh21AG15N8MFL) surpasses the casting steel of the 18Cr – 10 Ni type used for comparison in the entire range of climatic temperatures. In this part of the article, attention is paid to the particles of non-metallic inclusions (NMI) in the cast metal of nitrous steel as a factor that can affect the mechanical properties under static and impact loading at low temperatures. NMI in laboratory metal are globular oxysulfides, with SiO2 oxides in the central part and an outer layer formed by manganese sulfide MnS, with an average particle size of ~75 % up to 4 μm. It has been established that when testing casting steel for impact bending at –160 °C, these NMI do not serve as a source of crack initiation, do not contribute to their propagation and are in a fracture surface in isolated pits. Under tensile conditions at –110 °C, the yield strength of nitrogen containing steel increases by more than 1.7 times in comparison with the properties at +20 °C; ductility does not decrease when cooled to –110 °C. In this case, NMI particles are strongly deformed due to the development of cracks in their oxide part, and even when NMI reaches the surface of the sample in working part in the neck zone, they do not serve as a source of crack initiation. Cracks at the boundary “NMI/ deforming metal” are not formed. Even with a random arrangement of particles in the form of chains along the axis of application of the tensile load, at a distance of 5 – 20 μm from each other, pores do not form around the particles and merge into a crack nucleus. The results obtained correlate with the literature data that NMI can act as stress relaxers in ductile steels.
