AbstractA modified QuEChERS method using a GC-ECD to determine the multiple residues of pyraclostrobin, difenoconazole, dimethomorph and azoxystrobin and to indirectly determine the total residues of maneb, mancozeb and propineb by a GC-FPD (with an S filter) was established and validated. Meanwhile, field trials were conducted in accordance with good agricultural practice (GAP) to study their characteristics of residue degradation under the agricultural climate and cropping system of Guangxi Province. The separation effect of each target peak was good with a linearity range of 0.01–5 mg L−1, a limit of detection (LOD) of 0.003–0.015 mg kg−1 and a limit of quantification (LOQ) of 0.01–0.05 mg kg−1. The average recovery ranges of vegetable tomatoes and cherry tomatoes were 70.5–120.0% and 70.8–119.8%, respectively, with relative standard deviations (RSDs) of less than 7.1%. Field trials of seven fungicides in vegetable and cherry tomatoes showed that the half-lives (t1/2) of the dithiocarbamate fungicides (metiram, mancozeb, and propineb, defined as total residues determined as CS2), pyraclostrobin, difenoconazole, dimethomorph, and azoxystrobin were in the ranges of 5.2, 12.7–17.8, 7.6–7.9, 6.6–6.9, and 6.3–6.6 d in vegetable tomatoes, respectively. The cherry tomatoes presented ranges of 4.3–4.5, 10.8–11.8, 6.7–7.0, 5.4–5.5, and 5.9–6.2 d, respectively. Combined with the final residue and market monitoring results, the results show that cherry tomatoes have significantly higher terminal residues, initial deposits, and maximum residues of seven fungicides than vegetable tomatoes, and these seven pesticides can be detected in cherry tomatoes purchased from three markets. Therefore, cherry tomatoes may be regarded as representative varieties of tomatoes in realizing residual extrapolation for the establishment of the maximum residue limit (MRL) value of fungicides in tomatoes and for conducting market monitoring.

Abstract
Composite materials are granted first choice in the present manufacturing scenario due to their compatibility with tolerances up to 0.001 mm and lower weight. The research design works on the composites of the metal matrix, which are used primarily for aeronautical and industrial applications. Metal matrix composites are being used extensively in structural engineering. Silicon carbide and fly shell ash were used as compliance in aluminium alloys for the manufacture of metal matrix composites (LM13). The composite metal matrix is created employing Stir Casting method. When compared to open moulding, closed moulding, and cast polymer moulding, it is a less expensive and more effective method. The composites produced were then examined for mechanical properties, from the results it was found that the presence of ash and ceramic grains can adversely impact the properties of the composites and even make them brittle. It is time to change the mechanical properties of aluminium by creating hybrid composites with double and often triple-reinforced sections. Hybrid composites have greater performance, better tolerance to tear, low density, resistance to corrosion and strong rigidity over metal matrix composites. In this research an Al-Sic-fly ash composite is proposed and the mechanical properties of hardness, tensile strength, corrosion strength, micro structure analysis are investigated.

Authors: Bodzás Sándor 
Published: March 2022

Abstract
The aim of the thesis is the geometric design, CAD modelling and TCA of spur gear pairs having normal teeth based on the modification of the pressure angle. The first task is the geometric design and CAD modelling of the gear pairs (5 pairs are designed) where only the pressure angle is modified beside the constancy of the other initial parameters. The second task is to analyse the comparison possibility and the accuracy similarity of the 2D and the 3D models by the Hertz (equivalent) stress analysis. Finally, I give analysis of the maximum equivalent stress, normal stress and contact pressure for each pair while three teeth are rolling down on each other.

Abstract
The paper presents the results of studies of diamonds from Early Jurassic sediments making up the Nyurbinskoe buried placer of the Nakyn kimberlite field, unique in diamond reserves. The main task is to identify diamond distribution patterns in the deposits of the Dyakhtar Stratum (lower deposit) and the Ukugut Suite (upper deposit) within the placer. A comparative analysis of the typomorphic features of diamonds from the upper and lower deposits of the placer was carried out. Variations in the contents of crystals with certain properties that form the image of a diamond-bearing geologic object have been revealed. The zonal distribution of diamonds by characteristics in sedimentary deposits, regardless of their age, has been established. The properties of diamonds and their associations change within the placer, which is due to their redeposition during the Early Jurassic sedimentation.
Stages of Paleoarchean to Paleoproterozoic Basic–ultrabasic Magmatism in the Sarmatian Craton

Abstract
The early stages of basic–ultrabasic magmatism in Sarmatia are characterized by the appearance of ultrabasic rocks formed from the mantle with an abnormally high iron content. Therefore, it is important to study them as the source of information about the stages and causes of the activity of the mantle and its possible composition. This magmatism has been recorded in Sarmatia since the beginning of the Eoarchean. The relics of Eo- and Paleoarchean basic and ultrabasic rocks were found in the Dniester–Bug, Kursk, and Azov provinces, which underwent tectonic reconstruction in the Mesoarchean and Paleoproterozoic. Mesoarchean basic–ultrabasic magmatism is manifested in all provinces of Sarmatia and is represented by effusive and intrusive facies. The Mesoarchean greenstone belts composed of komatiites and basalts have been well preserved in the Middle Dnieper province; in other provinces, they are strongly deformed and form narrow linear structures. The Paleoproterozoic endogenous activity in Sarmatia differs from that in other regions in the almost complete absence of magmatism in the period 2.5–2.3 Ga and its significant manifestation 2.1–2.0 Ga. The magmatism in Sarmatia at this stage is similar in the ratios of basic–ultrabasic and granitoid complexes to the magmatism in South Africa but differs from that in Fennoscandia and Canada. The volume of granitoids coeval with basic rocks is larger than the volume of mantle magmatism. The igneous complexes formed 2.1–2.0 Ga in Sarmatia and South Africa are also similar in the presence of norites, the enrichment in Ni and platinum group elements, and the ratio of granitoids and basic–ultrabasic rocks. Magmatic activity (first of all, basic–ultrabasic magmatism in ancient cratons) is not a synchronous phenomenon on a planetary scale and varies greatly in the volume of produced material within the same time intervals. Early Precambrian basic–ultrabasic rocks (volcanics of greenstone belts, intrusions of large igneous provinces, and layered massifs) resulted from plumes, whose derivates formed within the lower and upper mantle and/or the upper mantle and crust, which determined the heterogeneous composition of igneous rocks. The spatial heterogeneity and nonsynchronic occurrence of basic–ultrabasic magmatism might have been due to impact events serving as the triggers of plumes.

Abstract
—We have studied the mineral composition of ores from the Pepenveem epithermal Au–Ag deposit, which is a promising new object of the Chukchi Peninsula. It has been found that the ore formation process was developed in the following sequence: Pyrite, arsenopyrite, and marcasite were deposited at the early stage, next were Pb, Zn, and Cu sulfides; at the late stage, native gold, pyrargyrite, stephanite, proustite, minerals of the pearceite–polybasite series, acanthite, and other Ag minerals were deposited. The results of fluid inclusion studies indicate that the Au–Ag mineralization formed from low-temperature (236–137 °C) low-concentration chloride hydrotherms (0.18–1.57 wt.% NaCl eq.). The results of calculation of thermodynamic equilibria have shown that in the temperature range from 200 to 100 °C, there were a decrease in the fugacity of sulfur (lg fS2 from –10 to –21) and oxygen (lg fO2 from &lt;–36 to &lt;–48) and a change from near-neutral to acidic solutions. Compared to other Au–Ag deposits on the Chukchi Peninsula (Corrida and Valunistoe), which are characterized by wide distribution of Se- and Te-bearing Au–Ag chalcogenides (naumannite, cervelleite, and hessite), ore formation with gold–silver–sulfosalt mineralization at the Pepenveem deposit took place at lower temperatures and lower selenium, tellurium, and oxygen fugacity. The data obtained permit us to refer the Pepenveem deposit to the group of epithermal low-sulfidation (LS) deposits.
Quantification of Temperature-Dependent Sorption Isotherms in Shale Gas Reservoirs: Experiment and Theory
Authors: Yang Yun , Liu Shimin , Clarkson Christopher 
Published: March 2022

Summary
A critical component of natural gas in organic-rich shales is adsorbed gas within organic matter. Quantification of adsorbed gas is essential for reliable estimates of gas-in-place in shale reservoirs. However, conventional high-pressure adsorption measurements for coal using the volumetric method are prone to error when applied to characterize sorption isotherm in shale gas systems due to limited adsorption capacity and finer pores of shale matrix. Innovative laboratory apparatus and measurement procedures have been developed to accurately determine the relatively small amount of adsorbed gas in a Marcellus shale sample.
The custom-built volumetric apparatus is a differential unit composed of two identical single-sided units (one blank and one adsorption side) connected with a differential pressure transducer. The scale of the differential pressure transducer is ±50 psi, a hundred-fold smaller than the absolute pressure transducer measuring to 5,000 psi, leading to a significant increase in the accuracy of adsorption measurement. Methane adsorption isotherms on Marcellus shale are measured at 303, 313, 323, and 333 K with pressure up to 3,000 psi. In addition, a fugacity-based Dubinin-Astakhov (D-A) isotherm is implemented to correct for the nonideality and to predict the temperature dependence of supercritical gas sorption.
The Marcellus shale studied generally displays linear correlations between adsorption capacity and pressure over the range of temperature and pressure investigated, indicating the presence of a solute gas component. It is noted that the condensed-phase gas storage exists as the adsorbed gas on the shale surface and dissolved gas in kerogen, where the solute gas amount is proportional to the partial pressure of that gas above the solution. One of the major findings of this work is the experimental observation of the contribution of dissolved gas to total gas storage. With adsorption potential being modeled by a temperature-dependence expression, the D-A isotherm can successfully describe supercritical gas sorption for shale at multiple temperatures. Adsorption capacity significantly decreases with temperature attributed to the isosteric heat of adsorption. Lastly, the broad applicability of the proposed fugacity-based D-A model is also tested for adsorption data provided in the literature for Woodford, Barnett, and Devonian shale. Overall, the fugacity-based D-A isotherm provides precise representations of the temperature-dependent gas adsorption on shales investigated in this work. The application of the proposed adsorption model allows predicting adsorption data at multiple temperatures based on the adsorption data collected at a single temperature. This study lays the foundation for an accurate evaluation of gas storage in shale.
Neocolonialismo como causa e Turismofobia como efeito: Uma aproximação a partir da Geografia
Authors: Gastal Susana de Araújo , De Sá Felipe Zaltron 
Published: March 2022

O estudo do Turismo ganha status acadêmico considerando-o como prática social e ciência inter e transdisciplinar que permite diálogos, entre outros, com os estudos geográficos. Tais aproximações levam a maior entendimento do mesmo, especialmente nas suas tensões decorrentes da estrutura econômica-capitalista que, desde o século XIX, se apropria das práticas e imaginários associados às viagens. Nesses termos, o presente artigo segue estrutura teórico ensaística apoiada em revisão de literatura, propondo repensar o Turismo e, mais especificamente, o overtourism e a turismofobia, a partir da Geografia. Apoia-se para tal em Rogério Haesbaert e seu texto no livro “O mito da desterritorialização: do ‘fim dos territórios’ à multiterritorialidade”, ali buscando as teorizações do autor no que refere à questões associadas ao território. Reforçam-se as fortes interfaces do Turismo com o[s] território[s] e encaminha-se que o overtourism e a turismofobia, mesmo que ainda não com esta denominação, já chamavam atenção acadêmica desde os anos 1960, em paralelo à expansão do dito Turismo de massa e a apropriação neocolonial dos territórios para fins turísticos, primeiramente na própria Europa para a seguir buscar territórios turistificáveis na periferia do capitalismo central, como América Latina e África.

Este artigo aborda acerca da racionalidade de diversos atores que são determinadas pelas relações de poder articuladas pelo processo de internacionalização do turismo. Também, diante do domínio de mercado turístico reflete-se sobre as atuações exógenas que exercem influência sobre a dinâmica do território do arquipélago de Bazaruto, assim como, sobre a lógica horizontal estabelecida por relações de vivência baseadas em laços de fortalecimento solidário. É neste contexto que, buscando materializar esta pesquisa de cunho qualitativo, com base na análise documental e bibliográfica, auxiliada da atividade em campo, interagiu-se com os sujeitos de pesquisa através da realização de entrevistas com membros da comunidade autóctone, empresários turísticos e funcionários da administração do Parque Nacional do Arquipélago de Bazaruto (PNAB). Também, realizou-se a observação direta e encontro participativo tendo em vista a apreensão das questões cotidianas do arquipélago de Bazaruto. Por meio do contato que a comunidade tem com o contexto turístico, a comunidade passa a ter novas exigências e procura as facilidades da vida moderna. Contudo, enquanto a comunidade local se preocupa com a disposição de serviços e a aquisição de bens de consumo tidos como o mínimo para a subsistência, as firmas, mediante a atuação em rede, procuram atender a acumulação de capital pelos níveis de domínio tecnológico, da organização do trabalho e de capital, assim como de expansão de atividades, a exemplo daquelas ligadas ao turismo. A dinâmica territorial torna-se, no entanto, dependente e propícia à abertura de projeções exógenas que se fundamentam na lógica hegemônica de importação e difusão dos modelos de consumo.

On the energetics of radical adduct formation of OH• with phenol analogs and aniline
Authors: Štellerová Dagmar , Lukeš Vladimír 
Published: March 2022

Abstract
Theoretical studies on aniline, phenol, benzenethiol, benzeneselenol, and their corresponding adducts with hydroxyl radical in possible positions on a hydrocarbon ring are presented. Bond dissociation enthalpies, related to radical scavenging of primary antioxidants, were calculated using the M06–2X/6–311+G** method. Calculated data were compared with available experimental data. Preferable homolytic bond dissociation of the presented molecules with OH• through functional groups X—OH followed by the m–OH ones has been confirmed. The highest antioxidant activity among the investigated positions is predicted for benzeneselenol. Also, the formation of non-covalent van der Waals structures has been shown as important in radical scavenging.
