The results of a geochemical study and paleogeographic, paleoclimatic interpretation for a cyclically constructed section of upper Cretaceous deposits near Volsk city, Saratov region, are presented. Elementary formation cyclites and cyclic variations of a number of certain parameters were associated with the Milankovich astronomical-climatic cycles. The curves of changes of paleotemperature, humidity, paleobathymetry were compiled. The results obtained give an idea of the migration of the arid belt boundaries in the upper Cretaceous and the overall climatic zonation, which is important for regional and global paleoclimatic reconstructions, as well as the history of the development of shelf seas that covered the Russian plate (especially Ulyanovsk-Saratov trough). Paleotemperatures of the land surface in the denudation areas are obtained from the chemical index of alteration (CIA). In the Turonian-Campanian interval selected climatic cyclicity, including period of relative cooling (Turonian–Coniacian) with paleotemperature about 20 °С, the period of relative warming in the mid-late Campanian (20–24 °С), the cooling time at the end of the late Campanian (19–21 °С) and the period of warming at the turn of the Campanian and Maastrichtian and in the early Maastrichtian time. In Maastrichtian age, there are two climatic cycles, beginning with a time of relative cooling (about 19 °С) and ending with a time of relative warming (about 20 С, at the end of Maastrichtian to 25 °С). The cycles of climate humidity change are also determined: two cycles in Campanian time, three cycles in early Maastrichtian, and one cycle in late Maastrichtian. The boundary of the early and late Maastrichtian corresponds to the change of arid conditions to humid ones. The paleobatimetry curves show transgressive-regressive cycles: one in the late Turonian-Coniacian time, two in the late Campanian time, five in the early Maastrichtian time, and one in the late Maastrichtian time. Depth variations were estimated: in the Turonian-Coniacian time in the range of 70–80 m, in the Campanian-Maastrichtian time, the paleobatimetry consistently increased and changed from 100 to 200 m (on average about 150 m). The results obtaired give and idea of the migration of the boundaries of the arid belt in the Late Creataceous and main features of the climatic zonation, which is important for regional and global paleoclimatic reconstructions, as well as for the history of the development the Russian plate in the Ulyanovsk-Saratov region.

Presents the results of magnetotelluric soundings acquired in 2020 along the profile Rzhev– Velikie Luki, in the suture zone of three parts of Precambrian crust of East European platform: Fennoscandia, Sarmatia and Volga–Ural. In the central part of the profile, anomaly zone of increased conductivity in the crust was revealed. The crust conductor is weakly expressed on the components of the telluric tensor due to the screening effect of the conductive sedimentary cover; therefore, the focus in the qualitative analysis of data and inversion was made on magnetovariational parameters.According to the results of two–dimensional inversion carried out in the program of A.E. Kaminsky ZONDMT2D, on the geoelectric model a subvertical zone of low resistivity in the crust is identified, which is probably associated with the paleosubduction zone of the Belarusian Ocean Plate.

Published: January 2022

This article displays data on cristobalite and tridymite from the Arsenatnaya active fumarole, the Tolbachik volcano, Kamchatka, Russia. The minerals occur in associations with fumarolic sylvite, sanidine, cassiterite, hematite, pseudobrookite, johillerite, tilasite, badalovite. Fumarolic cristobalite is tetragonal (-modification); the unit-cell parameters for one of samples are: а = 4,975 (7) Å, с = 6,944 (13) Å, V = 171,89 Å3. There are two types of tridymite — monoclinic (MC) and orthorhombic (PO-10) — in the Arsenatnaya fumarole. The unit-cell parameters of these tridymite modifications are: a = 18,553 (5), b = 5,006 (1), с = 25,952 (10) Å, = 117,68 (2)o, V = 2134,3 (11) Å3 (MC); a = 9,941 (2), b = 17,165 (4), с = 82,362 (18) Å, V = 14053,4 (29) Å3 (PO-10). Mineral assemblages of cristobalite and tridymite indicate high-temperature formation conditions of these minerals — not lower 450–500 °С — with a high participation degree of HCl and HF in process of basalt alteration by fumarolic gas. The surrounding basalt was a source of silicon. This element was, probably, transported in the form of SiX4, where X = F, Cl.

Published: January 2022

In the work the speciation of metals in the water and bottom sediments of the Malaya Senga River, located in the Petushinsky district of the Vladimir region were studied. It is shown that all studied metals in the waters are predominantly in a dissolved form. At the same time, most of Fe, Cu, Cd and Pb in river waters are in the form of complexes with organic substances (which are mainly represented by their negatively charged compounds), and the main forms of occurrence of Ni and Zn are inorganic compounds and cationic complexes with low molecular weight organic ligands.In bottom sediments for the metals, the share of migratory forms of metals relative to the total contents is from 10 to 30%, while a significant part of them is represented by forms associated with iron and manganese hydroxides.

Three series of experiments were carried out to study the possibility of replacing quartz sand in the initial charge for the production of glass with a silica clay. The experiments were carried out at atmospheric pressure and temperatures of 900–1200 С. It is shown that the complete replacement of quartz sand with a silica clay and the use of the presented initial compositions based on silica clay in the glass industry will lead to an increase in the temperature in the technological scheme of production, an increase in energy consumption and is economically unprofitable.Production schemes are promising, in which, along with the silica clay, the original charge contains cullet. It is shown that the disappearance of crystalline phases in this case in the samples with the addition of the silica clay occurs at a lower temperature than in the samples without the silica clay.

Published: January 2022

High-frequency electric field measurements with a regular receiving dipole characterized by poor electrode contact are greatly influenced by the capacitive currents arising between wires and ground. At the same time, making use of the non-contact receiving dipoles is not generally suitable for low-frequency electric field measurements.We introduce a novel hybrid galvanic-capacitive receiving dipole, which could be used for broadband electric field measurement even with high contact resistance of the grounded electrodes.

The article presents the results of the interpretation of magnetotelluric soundings performed in the Southern Ladoga region. When performing the 3D inversion, both new data obtained by the LADOGA working group in 2018–2021 and data from the profile 1-EV (the “Loop” section) worked out in the early 2000s were used. Based on the results of automatic inversion performed in the ModEM program (Egbert and Albert), a three-dimensional geoelectric model of the earth’s crust to a depth of 60 km is constructed, which shows the complex heterogeneous structure of the studied territory.In the geoelectric model, two anomalous zones of core electrical conductivity of the south-eastern and north-eastern directions are distinguished, the first of which is a continuation of the well-known Ladoga anomaly. The presence of the second conducting structure confirms the results of single magnetovariational sounding performed by Igor Ivanovich Rokityansky in different parts of the East European Platform in the early 80s of the last century.

ObjectiveTo assess the effect of uterine septum resection on reproductive outcomes of in vitro fertilization (IVF) / intracytoplasmic sperm injection (ICSI) in patients with secondary infertility complicated with uterine septum.MethodsA retrospective cohort study included 269 patients. Surgical group included 169 patients with secondary infertility complicated with uterine septum, who underwent 252 embryo-transfer (ET) cycles following septum resection. Control group consisted of 100 patients with secondary infertility and uterine septum, who underwent 178 ET cycles. Cumulative pregnancy rate and cumulative live birth rate after one complete assisted reproductive technology (ART) cycle were the primary outcomes.ResultsThe results showed that the cumulative pregnancy rate was higher in the surgery group, and statistically significant difference was observed in the cumulative pregnancy rate between the two groups (71.0 vs. 59%, P = 0.044). In fresh ET cycle, no statistically significant difference between the two groups was evident (54.9 vs. 40.6%, P = 0.061). Statistical analysis of other results of the fresh ET cycle did not differ significantly between the two groups. In terms of frozen embryo transfer (FET) cycle outcomes, the clinical pregnancy rate and delivery rate in surgery group were 52.7 and 38.2%, respectively, which were significantly higher than those in the control group (38.2 and 22.5%, respectively) (P = 0.028 and P = 0.011).ConclusionThe reproductive outcomes of IVF/ICSI after septum resection in patients with secondary infertility were better than that in the untreated group, suggesting that uterine septum resection can be performed in patients with uterine septum combined with infertility to improve their reproductive outcomes.

Published: January 2022

The fouling/wetting of hydrophobic membrane caused by organic substances with low-surface energy substantially limits the development of the membrane distillation (MD) process. The sulfate radical (SO4 ·−)-based advanced oxidation process (AOP) has been a promising technology to degrade organics in wastewater treatment, and peroxydisulfate (PDS) could be efficiently activated by heat. Thus, a hybrid process of MD-AOP via PDS activated by a hot feed was hypothesized to mitigate membrane fouling/wetting. Experiments dealing with sodium dodecyl sulfate (SDS) containing a salty solution via two commercial membranes (PVDF and PTFE) were performed, and varying membrane wetting extents in the coupling process were discussed at different PDS concentrations and feed temperatures. Our results demonstrated permeate flux decline and a rise in conductivity due to membrane wetting by SDS, which was efficiently alleviated in the hybrid process rather than the standalone MD process. Moreover, such a mitigation was enhanced by a higher PDS concentration up to 5 mM and higher feed temperature. In addition, qualitative characterization on membrane coupons wetted by SDS was successfully performed using electrochemical impedance spectroscopy (EIS). The EIS results implied both types of hydrophobic membranes were protected from losing their hydrophobicity in the presence of PDS activation, agreeing with our initial hypothesis. This work could provide insight into future fouling/wetting control strategies for hydrophobic membranes and facilitate the development of an MD process.

The application of marketing strategies within the company is very influential in the performance of the company concerned. The success or failure of the company is largely determined by how developed by the company to be able to compete for consumers in the implementation of an effective marketing strategy. Cafes that will be observed were located in Rengat. The choice of the objects because they have been existed until today, even though the Pandemic rises. Furthermore, The marketing strategy itself is a plan for implementing and controlling activities aimed at influencing exchanges in order to achieve organizational goals. Developing and implementing a marketing strategy, one of the stages is planning a marketing mix consisting of four elements, namely product, price, distribution/place, and promotion. Consumers are one of the most decisive elements. On the marketing variable, the Cafes should reconsider the amount of costs offered for sales, and managers should pay attention to the comfort of the consumers and increase promotion to get stability number of sales during pandemic. it is also necessary to take a stance to make improvements to previous program failures in achieving future targets. Cafes’ managers need to formulate short-term, medium-term and long-term goals so that it needs to strive to build positioning in the community.

Handing down the land : Origins and recent shifts in the problem of the Other, Bernard Derouet
The problem of the Other is at the heart of the study of family reproduction. But the questions it raises have been thoroughly overhauled within this framework. There is an increasing awareness that, alongside the old questioning of spatial diversity, which must be reformulated along new lines, other dimensions of otherness exist, particularly with regard to the insertion of pratices within history. Thus one is compelled to picture the handing over and the transfers which go with it in the light of their articulation with a set of social practices within which these transfers are only one element in a more complex mechanism. A new approach, shunning the institutional construction of family systems as well as the atomized view of individual strategies, and centered on the necessity to take into account the multiple levels of otherness, would develop first and foremost the concept of "alternative solution".

Buckwheat Diffusion in Modern France Michel Nassiet
First attested in lower Normandy in the middle of the Fifteenth century, the cultivation of buckwheat had spread over the entire Armorican massif by the Sixteenth century, then to Champagne Sèche, and to the Limousin and Auvergne in the Seventeenth century, where the grain was used for human consumption. This plant is well suited to acidic soils, and its spread was limited by pedological and pluviométrie constaints. In the Massif Central, where crops were rotated biennially, buckwheat was planted only as a replacement for other cereals. In the Armorican massif, an area of triennial crop rotation, its propertied as a summer cereal and its astringent qualities allowed for it use at the beginning of the rotation, and made fallow land productive. Its spread and inclusion in crop rotation probably caused a noticeable rise in global grain production. This growth contributed to population growth in the Armorican massif in the Sixteenth century. On the northern coast of Brittany, the surplus of exportable grain made possible a partial reconversion to the cultivation of flax, and thus to canvas manufacturing.

Предрасполагающими факторами развития опухолей нёбных миндалин могут быть употребление алкоголя и длительное курение, различные рецидивирующие вирусно-бактериальные заболевания, приводящие к хроническому воспалительному процессу. Канцерогенные вещества, содержащиеся в табачном дыме, являются ведущей причиной возникновения воспаления слизистой оболочки, а алкоголь (спирт), как полагают, действует синергично с канцерогенными компонентами табачного дыма. В настоящее время увеличение заболеваемости раком миндалины также связывают с вирусом папилломы человека 16-го и 18-го типа. За последнее десятилетие отмечается тенденция к росту показателей заболеваемости и смертности среди пациентов с раком нёбных миндалин. За десятилетний период наблюдения уменьшилась доля случаев ранней и своевременной диагностики в 1,2 раза с 27,0% в 2011 г. до 22,4% в 2020 г. В 1,6 раза увеличилось число случаев заболевания в далеко зашедших стадиях (29,1% в 2011 г. и 45,6% в 2020 г.). В статье представлены данные о динамике грубых интенсивных показателей заболеваемости и смертности в отношении злокачественных новообразований нёбных миндалин.
Tumors of the palatine tonsils do not have a specific etiology; only a number of factors are known that increase the risk of their development. The predisposing factors can be of various reasons, such as alcohol consumption and prolonged smoking, various recurrent viral and bacterial diseases that lead to a chronic inflammatory process. Carcinogens in tobacco smoke are the leading cause of mucosal inflammation, and alcohol is believed to act synergistically with the carcinogenic components of tobacco smoke. Currently, the increase of the incidence of tonsil cancer is also associated with human papillomavirus of the types 16 and 18.Over the past decade, there has been the tendency towards the increase of morbidity and mortality among patients with cancer of the palatine tonsils. Over the ten-year observation period, the share of early and timely diagnosis cases decreased by 1.2 times from 27.0% in 2011 to 22.4% in 2020.The number of cases in advanced stages increased significantly, by more than 1.6 times (29.1% in 2011 and 45.6 in 2020). The article presents data on the dynamics of rough intensive indicators of morbidity and mortality from malignant neoplasms of the tonsils.
