Globally, COVID-19 has had a negative impact on health systems and health outcomes, with evidence of differential gender impacts emerging. The COVID-19 timeline of events spanning from closures and restrictions to phased reopenings is well-documented in Kenya. This unique COVID-19 situation offered us the opportunity to study a natural experiment on pregnancy trends and outcomes in a cohort of Kenyan adolescent girls and young women (AGYW), enrolled in the KENya Single-dose HPV-vaccine Efficacy (KEN SHE) Study. The KEN SHE Study enrolled sexually active AGYW aged 15–20 years from central and western Kenya. Pregnancy testing was performed at enrollment and every 3 months. We determined pregnancy incidence trends pre- and post-COVID-19 lockdown, pregnancy outcomes (delivery, spontaneous, or induced abortion), and postabortion and postpartum contraceptive uptake. Kaplan–Meier survival estimates of incidence rates were used to estimate the cumulative probability of pregnancy during the study period. Cox regression was used to investigate factors associated with pregnancy incidence. Of the 2,223 AGYW included in the analysis, median age was 18.6 IQR (17.6–20.3), >90% had at least secondary school education, 95% were single at the time of enrollment, and 82% had a steady/primary sexual partner. Pregnancy incidence peaked at 2.27 (95% CI [1.84, 2.81])/100 women-years of observation at the end of the first quarter of 2020, a period coinciding with the government-imposed lockdown. AGYW had 60% increased risk of being pregnant during the lockdown when compared to prelockdown period (HR = 1.60, 95% CI [1.25, 2.05]). Among the 514 pregnancies reported, 127 (25%) ended in abortion, of which 66 (52%) were induced abortions. Our findings demonstrate the adverse sexual and reproductive health (SRH) consequences of the COVID-19 pandemic and the lockdown measures among AGYW. As services continue to be disrupted by the pandemic, there is an urgent need to strengthen and prioritize AGYW-centered SRH services, including contraception and safe abortion.

Viscosity is one of the factors affecting the performance of the auger pump. An auger pump is positive-displacement (PD) pump that moves fluids and semi-solid material along the screw axis using one or more screws. The study is about the analysis of the performance of the auger pump when transferring various viscosity liquids. In the study, a pumping device with auger shaft is designed. The sample liquids chosen for the experiment oil and concentrated detergent that poses various viscosity. The viscosity is being identified roughly by Zahn Cup Method with the temperature kept constant at 26°C throughout the measurement. The performance of the auger pump can be accessed by altering the motor speed in order to get various reading for the flow rate and pressure. It is found in the study; flowrate is affected by viscosity with the increasing motor speed. The study proves that the auger pump can operate with viscosity of 770 cSt liquid.

Published: December 2022

Numerical control is a useful technology to control a machine that utilize numeric values and codes. The machine comes with various sizes and built-in with its own controller. However, most of the commercial CNCs controllers are expensive and work only on the dedicated machine. With recent advancement of automation, a custom conrtoller for CN machine operation is possibly to be build. In this project, the three axis motion is controlled by Arduino Uno board with Atmega 328p microcontroller. In this case, the Arduino serves as an open source burner that burns the microcontroller using the provided programmes. Stepper motor drivers and the CNC shield accept signals from the Arduino board and transmit power to the stepper motors. Using Inkspace software, the user must first convert any image or text file into G-code before feeding it to the machine. The G-code file is then browsed in Universal G-code Sender software connected to a GRBL shield v0.9i and Arduino board through a laptop serial interface. The Universal G-code Sender programme has a G-code visualizer feature that allows to see the manufacturing processes alongside the simulation.
Rare distant metastases to pancreas, liver, and lung as initial presentation of mixed tall cell and columnar cell variants of papillary thyroid cancer
Authors: Harper Cody , Michael James , Rahmeh Tarek , Munro Vicki
Published: December 2022

The most common sites of distant metastases of papillary thyroid carcinoma (PTC) are lung and bone. Widespread distant metastases of PTC are rare and associated with poor overall prognosis. Metastases to sites such as liver and pancreas are extremely rare, and literature is sparse on overall survival. In this report, we present a 57-year-old man whose initial presentation of PTC was with pancreatic, liver, and lung metastases, and subsequently developed metastases to bone and brain. He underwent a total thyroidectomy, neck dissection, and tracheal resection. Pathology revealed a predominant columnar cell variant PTC with focal areas of tall cell variant, and genomic sequencing showed both PIK3CA and BRAF gene mutations. Radioactive iodine ablation with I-131 did not show any uptake in metastatic sites and he had progression of the metastases within 6 months. Therefore, therapy with lenvatinib was initiated for radioactive iodine refractory disease. Our patient has tolerated the lenvatinib well, and all his sites of metastases decreased in size. His liver and pancreatic lesions took longer to respond but showed response 6 months after initiation of lenvatinib, and he remains on full dose lenvatinib 18 months into treatment.

Learning points

Papillary thyroid carcinoma (PTC) usually metastasizes to lung and bone but can rarely occur in many other sites.

Patients with distant metastases have significantly worse long-term prognosis.

Lenvatinib can be an effective treatment of radioactive iodine refractory PTC with rare sites of distant metastases.

Lenvatinib can be an effective treatment of PTC with BRAF V600E and PIK3CA mutation.
Validación del compost producido a partir de especies invasoras como sustrato de propagación en el proceso de restauración ecológica
Authors: Azula-Barrera María Catalina
Published: December 2022

[Introduction]: The control and management of invasive species generates high volumes of waste material whose management and disposal becomes a problem. The use of this waste material through the composting process could lead to a substrate with potential use as germination and propagation substrate of native species, therefore giving possible solutions to the quantity of mass generated in the control. [Objective]: Validate the compost produced from invasive species as a potential substrate for propagation and growth of native species within the process of ecological restoration in Bogotá - Colombia. [Methodology]: Fifty seeds of three native species were sown in five treatments with different proportions of black soil and compost. The compost raw materials were Ulex europaeus L and Genista monspessulana (L.) L.A.S. Johnson. To evaluate its use germination, mortality, epigeal and hypogeal growth were measured. [Results]: Verbesina crassiramea S. F. Blake showed the highest germination in the substrate with 100 % compost followed by 0 % compost, 75, 50 and 25 % respectively. Dodonaea viscosa (L.) Jacq., showed a germination gradient of 75 compost, followed by 50, 100, 0 and 25 %. Duranta mutisii L.f. had an inverse germination gradient. The substrate with 25 % compost caused the lowest germination and highest mortality of Dodonaea viscosa and Verbesina crassiramea. Dodonaea viscosa grew best in substrates with 75 % compost, with the highest germination value, root growth, aerial development and biomass generated. [Conclusions]: Compost from invasive species, can be used as a substrate for the propagation of native species in early stages, the expression of invasive species was not evidenced, being an alternative to reduce the demand of soil.

Powder processing of the P6M5K5 alloy in rolls of the rolling mill has been performed. There was no contamination, and the oxygen content was not increased during the processing. Processing of the sprayed powder of the P6M5K5 alloy was carried out on a two-roll press DUO 180 with a speed of rotation of 10 rpm. Only one of the rolls was rotating, which made it possible to carry out a combination of three types of impact on the material - compression, impact, and abrasion. The gap between the rolls was zero. The number of processing passes varied from 5 to 20. For the use of powder in 3D printers, the optimal fractional composition of the powder is from 50 μm to 160 μm. The fractional composition of the powder was measured by its dispersion on a vibrating sieve analyzer of the ROTAP type. Since the process of destruction of any brittle material depends on their initial properties, the grinding of this material on a rolling mill cannot be quantitatively unambiguous. In processing the powder, rolling of the powder dominated, and the particles themselves were not easily destroyed. The reason for this turned out to be insufficient rigidity of the DUO 180 rolling mill for this powder. As a result of the processing of the P6M5K5 powder in the rolling state, the fluidity of the powder significantly decreased by more than 2 seconds from 22 s to 20 s, which is 10%. This is evidence that a rolling process took place, which led to a decrease in the number of satellites. Five cycles of processing the powder in the rolling mill were enough to reduce the fluidity by 10%. Increasing the number of processing cycles to 20 did not change the fluidity of the powder, but led to its slight grinding. Keywords: P6M5K alloy powder, rolling, grinding, fractional composition of the powder.

The physicochemical characteristics of phycocyanin extracted from cyanobacteria collected in Kaunas Lagoon were studied (spectrum characteristics, C-PC content in the dry mass and chemical purity). It was determined that the tested concentrations of C-PC in purified water should be in the range of 0.02–0.16% for measuring C-PC content in the dry mass and its spectrum characteristics. The two clear absorption maxima were detected in the spectrum of C-PC at the wavelengths of 277 and 619 nm. The content of C-PC in the dry powder form was in the range of 7.25% to 9.30% depending on its concentration in the solution and type of spectrophotometer. Furthermore, a purity factor of 1.5 was calculated, which indicated the food qualification of the obtained biomass of C-PC. Finally, the analytical procedure for studying the pro- and anti-oxidant activity of C-PC was developed and the antioxidant activity of C-PC was measured for the available markers. It was revealed that C-PC has dual properties (pro- and anti-oxidant ones) depending on its concentration, more exactly, its content in reaction mixtures with 2,2-diphenyl-1-picrylhydrazyl (DPPH). The following issues were resolved during the research: the concentration of ethanol in the DPPH solution was chosen in order to avoid precipitation of proteins in the reaction mixtures (50%); the ratio of the solution of C-PC to the DPPH solution was selected; the selected concentrations of the markers for the construction of their calibration curves were chosen for quercetin and for rutin. The antioxidant activity of the obtained C-PC sample was determined. Keywords: antioxidant activity, C-phycocyanin, cyanobacteria, DPPH, quercetin, rutin

The aim of the study was to evaluate changes in the activity of acid and alkaline phosphatases, calcium and phosphorus levels in rats with different courses of experimental gingivitis upon treatment with anti-inflammatory gel with Neovitin and peptide complexes. The experiment was conducted on 100 white nonlinear male rats aged 5-6 months divided into 10 groups: 1 control and 9 – with different courseі of gingivitis. The activity of alkaline and acid phosphatase (ALP, ACP), the levels of calcium (Ca) and phosphorus (P) in rat blood serum and gingiva supernatant were determined. It was found that upon gingivitis, the activity of ALP in blood serum decreased and in gingiva supernatant increased in all groups of animals compared to the control group. The activity of ACP in the serum decreased in hypoergic and hyperergic animal groups and increased in normergia, and in gingiva supernatant increased in all groups: by 2 times in normoergic and hypoergic animals and by 1.4 times in hyperergic. The treatment with anti-inflammatory gel normalized the activity of ALP in both serum and supernatant and decreased the ACP activity in the serum of animals in hypo- and hyperergic groups. The content of serum Ca increased in all groups, and in the supernatant of the gingiva even exceeded the control value. The content of phosphorus in the supernatant of periodontal tissues decreased. The development of the inflammatory process in the periodontium of rats with gingivitis was accompanied by changes in the activity of ACP, ALP, the content of Ca and P in the blood serum and gingival supernatant. The treatment with gel containing neovitin and peptide complexes had a more pronounced therapeutic effect in rats with unchanged reactivity of the organism.

Toxocariasis is common among children and causes digestive diseases. The aim of the work was to study the development of toxocariasis in children with digestive diseases. The serum levels of specific IgG to Toxocara canis and Ascaris, levels of IL-4 and TNF-α were determined in 63 children. In addition, tests for parasites and a retrospective survey in order to assess sanitation and hygiene practices were conducted. All children were divided into two groups: group I includes 19 (30.2%) patients seropositive for toxocariasis, and group II – 44 (69.8%) children without any parasites. The level of IL-4 was higher in group I (18.0 ± 6.4 pg/ml) than in group II (7.2 ± 2.0 pg/ml) (P < 0.001. While the level of TNF-α did not differ significantly between groups I (4.5 ± 2.1 pg/ml) and II (3.6 ± 1.1 pg/ml) (P > 0.05). A higher incidence of Toxocara was observed among rural residents (78.9%). Children with toxocariasis more often had soil-pica (42.1%), played with dogs (100%), and did not wash their hands (84.2%) compared to the group of uninfected children. It was noted that hygienic habits and place of living contribute to Toxocara canis infection. IL-4 levels were considerably higher in group I than in group II that can be accounted for the host immune response activation, at the same time, the levels of TNF-α did not differ. Children without toxocariasis had also increased levels of IL-4, which may be related to past helminthic infection.

Nurse Education and Hospital Readmissions for Children With and Without a Mental Health Condition
Authors: Riman Kathryn A. , Doupnik Stephanie K. , Kutney-Lee Ann M. , Lake Eileen T.
Published: December 2022

OBJECTIVES:

In adults, receiving care in a hospital with more baccalaureate-prepared nurses improves outcomes. This relationship is magnified in adults with serious mental illness or cognitive impairment. Whether the same is true in children with and without a mental health condition is unknown. The study purposes were to determine 1) whether the proportion of baccalaureate-prepared nurses affected the odds of readmission in children; and 2) whether this relationship differed for children with a mental health condition.

PATIENTS AND METHODS:

We linked cross-sectional data from the 2016 Healthcare Cost and Utilization Project State Inpatient Databases, the RN4CAST-US nurse survey in Florida, and the American Hospital Association. Inclusion criteria were ages 3 to 21 years. Mental health conditions were defined as psychiatric or developmental/behavioral diagnoses. These were identified using the Child and Adolescent Mental Health Disorders Classification System. We used multivariable, hierarchical logistic regression models to assess the relationship between nurse training and readmissions.

RESULTS:

In 35 081 patients admitted to 122 hospitals with 4440 nurses, 21.0% of patients had a mental health condition and 4.2% had a 7-day readmission. For individuals without a mental health condition, each 10% increase in the proportion of baccalaureate-prepared nurses was associated with 8.0% lower odds of readmission (odds ratio = 0.92, 95% confidence interval = 0.87–0.97). For those with a mental health condition, each 10% increase in the proportion of baccalaureate-prepared nurses was associated with 16.0% lower odds of readmission (odds ratio = 0.84, 95% confidence interval = 0.78–0.91).

CONCLUSIONS:

A higher proportion of baccalaureate-educated nurses is associated with lower odds of readmission for pediatric patients. This association has a larger magnitude in patients with a mental health condition.
ontologia social de Max Weber
Authors: Sell Carlos Eduardo , Bolda Bruna dos Santos
Published: December 2022

O artigo apresenta uma releitura da sociologia de Max Weber com base no individualismo âncora de Brian Epstein. Após apresentar a reflexão de Gert Albert sobre a ontologia de Weber, reconstruímos, em suas linhas gerais, os conceitos de anchoring e grounding da ontologia individualista de Epstein. Demonstramos, assim, que para Weber o nível social está “ancorado” nos indivíduos concebidos em sua dupla dimensão de seres biopsicológicos e socioculturais. Em relação ao “fundamento” [grounding] do social, mostramos que o conceito de ação com sentido pode ser lido como uma forma de projeção mental que encontra sua tradução coletiva na dimensão das relações sociais institucionalizadas [ordem social]. Dessa forma, a relação entre o nível institucional e o nível individual não é pensada em termos de causação direta, mas enquanto “dependência” [grouding].

Published: December 2022

In this work, functionalized reduced graphene oxide–silver (FrGO–Ag) nanocomposite was synthesized to enhance the antimicrobial activity and biocompatibility of FrGO for infected wound burn treatment. The reduction of GO and FGO was confirmed by the removal of some of the oxygen functional groups (carbonyl and epoxy groups) as revealed by Fourier transform infrared (FTIR) spectra. The face-centered cubic (fcc) silver nanoparticles were identified by X-ray diffraction (XRD). The contact time effect and the dose effect of the antimicrobial activity of rGO, FrGO, and FrGO-Ag nanocomposite toward Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans have been investigated. The cytotoxicity results of these compounds revealed that the functionalization by PVP and the decoration by AgNPs improved the biocompatibility of rGO sheets from 35.2 to 88% cell viability against the BJ1 normal human epithelial cell line.

Social Distance and Intergroup Contact
Authors: Ata Abe W , Baumann Klaus
Published: December 2022

The effects of intergroup contact in reducing prejudices have been well documented, but few studies have investigated the importance of the broader context within which contact occurs. This article examines the predictors of social distance from Muslims in a large sample of (non-Muslim) German university students (N = 404). Intergroup contact was an important predictor of reduced social distance even after demographics and perceptions of parents, tertiary institutions, media and broader intergroup dynamics were taken into account. The contact-social distance relationship was, however, mediated in part by perceived parental support for intergroup relations and perceived fairness of media representation. Students’ perceptions of broader group dynamics relating to assigning positive and negative attributes largely impeded the relationship – more so for male students than female. The findings attest to the importance of the broader context within which contact occurs. Having contact with outgroup members leads to reduced social distance from the outgroup, but perceived norms and outgroup perceptions play a pivotal role in explaining this relationship.

Published: December 2022

The problem of environmental protection arose in the middle of the 20th century and remains relevant to this day. Plastic, being an important material in almost all branches of industrial production, causes irreparable damage to nature, animals, and human beings. Many states have decided to start combating environmental pollution with plastic by developing various measures, starting with increasing the level of environmental literacy of the population and introducing mandatory garbage sorting, ending with the introduction of taxation of plastic waste. In this article, the authors reviewed recent legislative initiated by Western countries aimed at taxation of non-recyclable plastic, studied the features of such taxation mechanisms, and also identified imperfections in current versions of the legislation. In particular, the authors came to the following conclusions: the mechanism of the non-recyclable plastic tax in the EU is not perfect and requires additional improvements in terms of determining the elements of the tax; the predicted amounts of the non-recyclable plastic tax collection are relatively small in comparison with the total budget revenues of the EU; the actual impact of the introduced tax on the increase in the level of plastic recycling has not been proven, and the existing mechanisms of its work, preliminary studies and assessments indicate that its main goal is the growth of recycling materials to reduce disposable waste - probably will not be achieved in the current version of the law and taking into account the speed of adoption and implementation of this law on the territory of the EU. The identified problems require additional study based on successful examples of similar taxes introduced in other countries, e.g., in California (the USA).

Published: December 2022

This study aims to examine the impact of banditry on Nigeria’s agricultural output with an emphasis on herdsmen attacks between 2014 and 2020. The study employs a quantitative research method, with the source of data being a secondary source. The proxies used for the independent variable are the total number of deaths resulting from pastoralists’ attacks, the total number injured by pastoralists, and the total number of internally displaced persons, while the agricultural output percentage of GDP was used to proxy the dependent variable. The data was collected from the Central Bank of Nigeria (CBN) Statistical Bulletin, 2020, the Global Terrorism Database, 2020, and the Internal Displacement Monitoring Center Database, 2022. The data was analysed using Auto-regressive Distribution Lag (ARDL). The results of the study show that as the number of deaths from herdsmen attacks increases the agricultural output decreases, while the number of injured from herdsmen attacks has no significant effect on the agricultural output. Furthermore, the results reveal that as persons become displaced internally, agricultural output rises. The study recommends that the government should provide more securities aid to the farming communities, provide adequate healthcare for these communities, and also help the internally displaced farmers and others to settle quickly to their new environment and provide them with adequate tools to engage effectively in agricultural activities.

Published: December 2022

The need for the development of the economy and its constant modernization in accordance with the demands of the external and internal environment require the construction of a new type of economy that actualizes the key role of human in it. The experience of socio-economic transformations in various countries shows that inattention to a human, his absence as a core-forming element in the economic system contributes to crises and recessions. Accordingly, there is a change of priorities towards a human-oriented economy. The purpose of the study is to develop a typology of the species diversity of a human-oriented economy. The methodological basis of the study was the systemic and categorical-systemic approaches. Methods were applied: content analysis, “Range of information criteria”. The following results of the study were obtained: 1) the variety of types of economic systems is indicated; 2) a typology of the species diversity of a human-oriented economy has been developed on the basis of its fundamental spheres that ensure the satisfaction of human needs, based on its threefold nature; 3) thirty-six types of humancentered economy are identified on the basis of combinations of its core-forming spheres; 4) possible directions of the development of a human-oriented economy are substantiated by identifying its type and determining the vector of “movement” along the trajectory of the species diversity; 5) the possibility of building management mechanisms by determining the current type of human-oriented economy and the image of its desired future is argued; 6) it is substantiated that the typology of the species diversity of a human-oriented economy is the basis for the development of preventive measures to prevent the regressive development. The practical and theoretical value of the conducted research is the possibility of further research to identify the level of development of the human-oriented economy and develop the directions of management decisions on this basis.

The article discusses the features of the macro-environment development of small and mediumsized business (SMEs) in the region. The study is based on the understanding of entrepreneurship as an independent process of organizing financial and economic activities. The factors of sustainable development of small and medium-sized business that must be taken into account when studying any region of the Russian Federation are identified: the economic and geographical position of the region, state and regional support for small and medium-sized businesses, labor resources, demand and markets, territorial tax benefits, administrative barriers. Based on them, this article analyzes the measures of state and regional support for small and mediumsized businesses. The relationship between the tools to support the business environment and the dynamics of development and exit from the shadow and legalization of the activities of business entities is characterized. The most effective instruments of institutional support and ways to improve the institutional environment for SMEs both in Russia and in the Volgograd region in particular have been identified. The author’s approach to the provision of measures of state financial support to business entities within the region is presented. The article substantiates the need for a mechanism for zoning state measures. It is advisable to apply the ranking of the measures of state financial support provided, depending on the priority of the activities of SMEs and on the territorial location of the place of doing business.

The principles of the economic development of the global economy before the series of world covid restrictions were the unity of the world economic space, the priority of human and business rights for unhindered movement and economic activity, the stability of global and national legislation. The economic impacts of the COVID-19 have demonstrated the willingness of the global community to abandon these principles, which led to the isolation of national economies and an increase in the importance of the geographical and national origin of the counterparty. At the same time, the demand of subjects of economic relations for the ability of business to function in non-standard situations, up to the situation of a “perfect storm”, has grown. At the same time, the importance of the intensive use of technology and human capital has increased not only as possible elements of the company’s competitive strategy, but also as conditions for the presence of a subject of economic relations in the market. The increase in geopolitical instability in the context of the continued risks of countries imposing restrictions on movement in 2022 has become a factor that enhances the importance of national technologies and human capital as a condition for the economic security of the national economy. An increase in the volatility of energy and other markets can become a trigger for rethinking the basics of the investment process, taking into account the importance of the partner company’s nationality and the politicization of the investment process, especially in the areas of creating innovations and reproducing human capital. The article collected and analyzed the most significant facts that require a rethinking of approaches to innovation, investment and human capital. Based on the results of the analysis, a range of solutions was proposed regarding the use of the results of such a rethinking in terms of the development of the innovation and investment climate in Russia and the Russian system of human capital reproduction.
Reduced wettability in compacted coal fly ash due to organosilane treatment

Organosilane (OS) treatment for water repellency has gained attention as a mechanism for mitigating leaching and for possible beneficial reuse of coal combustion residuals, particularly coal fly ash (CFA). However, little effort has been devoted to understanding the interaction between OS-treated CFA and water under conditions representative of field applications. In this study, the construction conditions of OS-treated CFA were simulated in the laboratory, and the degree of induced water repellency was investigated through contact angle measurements. A class F CFA from a coal-fired electric power plant ash impoundment and a commercially available OS were used. Besides CFA geotechnical and geochemical characterisation, samples were prepared by post-compaction treatment of CFA with OS solutions applied by spraying, which simulates a field irrigation truck. Results indicate that a 7% volume concentration of the OS solution is appropriate for construction purposes. However, the degree of water repellency, as measured by using contact angles, is strongly dependent on the water content of the compacted CFA. This suggests that the contractor should compact the CFA first, then apply truck-mounted jet drying or a similar technique and finally spray the OS solution on the surface. Results also demonstrate that about 84% of the treatment accumulates in the upper 5 cm of the compacted CFA.

Monitoring the state of natural and technical systems in urban areas using remote methods allows not only to fix zones of anomalies of various genesis, but also to create opportunities for predicting areas of suffusion cavities occurrence and their growth rate before appearance on the surface. To determine the scenarios of sinkhole formation, a physical hydrogeological modeling was carried out. Non-destructive testing methods may play an important role in the localization of potentially dangerous areas with disturbed physical and mechanical properties of natural and technical systems. The revealed regularities make it possible to carry out predictive assessments and identification of hazardous processes.

The results of comprehensive petrological, geochemical, and mineralogical studies of effusive volcanic rocks from the diamond-bearing Tolbachik fissure eruption of 2012-2013 (TTI-50) are summarized. It is concluded that the eruption was two-phase, which began with a short-term eruption of trachybasalts and continued with the formation of trachyandesite basalts. In comparison with lavas from other Tolbachik eruptions (BTTI, BD), the studied volcanic rocks are characterized by higher alkalinity and high K content (up to shoshonites), but lower Mg content. In terms of geochemical properties, they correspond to riftogenic magmatites formed due to the deep-mantle chamber of picrite magma. The studied volcanic rocks are characterized by widely varying vesicularity up to bubbly lavas, which comprise 80-90% of volcanic glass, and whose degree of recrystallization varies from maximum in basaltic trachyandesite to minimum in trachyandesitebasalt bomb. According to the degree of iron oxidation in the glass phase, volcanics correspond to the products of terrestrial eruptions in an island-arc or continental-rift geodynamic setting. The microlites are dominated by olivine Fo56-84, plagioclases An87±9 Ab9±10 Ort4±2, and spinel solid solutions based on magnetite, magnoferrite, ulvite, and cuprospinel. Individuals of decomposition in phase-heterogeneous grains of magnetite are represented by hemoilmenite and ilmenite. As accessory microminerals, jirite-spionkopite of composition Cu1.7S-Cu1.32S, native iron composed of Fe75Sn4(Cu,Mn,Cr), and native copper of composition Cu7-10(Sn0.9-1.8Fe0.1-0.2)1-2

The article presents the results of studying the amphibolites of the Nyartinskiy Complex and the Mankhobeyskaya Suite. Based on the petrographic and mineral features of the rocks and the chemical zoning of the garnets, two episodes of metamorphism manifestations have been established. The first episode is characterized by a higher temperature (500 amphibolite facies (B3). The pressure at this stage is estimated at 6 10 kbar. The second episode corresponds to low-temperature diaphthoresis (284 4). Similar conditions of the rocks metamorphism of the Nyartinskiy Complex and the Mankhobeyskaya Suite confirm the idea that Mankhobeyskaya Suite is not an independent stratigraphic unit, but is a complex of low-temperature diaphtorites in rocks similar to those that compose the Nyartinskiy Complex.

This article discusses the results of a study in solving the inverse problem of gravimetry. It is shown that the solution of the inverse problem should be conducted in two stages. At the first step, the contour of the area occupied by gravitation masses is determined using the Laplace equation. At the second step, a generalization of the Poisson equation is used to determine the density distribution of the masses that fill the area, whose contour is determined at the first step. In this case, when setting the problem of analytic continuation, the provisions of potential theory are applied. The results of numerical calculations are presented on a model example with the determination of unknown values of density and values of the gravitational field inside a region filled with gravitation masses.

It is shown that an external gravitational action onto the planet core leads to the generation of its magnetic field. The natural phenomena as earthquakes, orogeny, oceanic currents, tides, time and solar day sudden changes, periodic solar activity, which can be easily explained with proposed mechanism of planets interaction are considered. Clear relationship of planets magnetic fields, their forms and value from solar activity, magnetic and gravitational fields measurements, oceanic level monitoring, as well as natural processes observation data may be accepted as evidence. Analysis of all the data leads to the unique conclusion about the influence of Earth’s core movement to many processes occurred and measured on the planet surface. Proposed approach allows integrating many separate processes to the single hole.
