Published: January 2022

For Fangshan granite in Beijing, the static compression and dynamic compression tests have been carried out separately under natural air drying and water saturation. It was found that the dynamic compressive strength of water-saturated granite is higher than that of air-dried granite, which is contrary to the result that the strength of water-saturated rock is lower than that of air-dried granite under static load. Furthermore, under the medium strain rate condition, when the strain rate is 85 s−1, the dynamic strength of natural air-dried granite could be increased by nearly 0.5 times compared with its static state. The dynamic strength of water-saturated granite could be increased by nearly 1–2 times compared with its static strength, which shows that water-saturated granite has stronger strain rate sensitivity than natural air-dried granite. Meanwhile, under impact loading, from the perspective of water-bearing granite the Bernoulli effect of fluid, the adhesion effect of free water and the Stefan effect of fluid in water-saturated granite were revealed, and found to be the essential reasons affecting the dynamic strength of water-saturated granite. The dynamic strength in different water-bearing states in the range of medium strain rate could then be analyzed in depth, providing a certain reference value for the strength design of water-bearing rock engineering.

Sediment nutrients can be released to the surface water when hydraulic disturbance becomes strong in shallow lakes, which contributes to nutrient enrichment and subsequent lake eutrophication in the water column. To explore the seasonal variations and spatial distributions exhibited by nutrients in the water column, surface sediment, and pore water of Lake Yangcheng and its major tributaries, we determined the concentrations of nitrogen (N) and phosphorus (P) throughout the lake in different seasons of 2018. Total N (TN) and total P (TP) concentrations in the connected rivers were much greater than those in the lake, indicating that external loading greatly contributed to the nutrient enrichment. TN concentration in the water column was highest in the winter, whereas TP peaked in the summer. A similar temporal pattern was observed for TN and TP in the sediment with maxima in the winter and minima in the summer; however, nutrients in the pore water were highest in the summer, in contrast to the temporal variation in the sediment. Additionally, high TN values in the water column and high TP in the three compartments were distributed primarily in the west part of the lake, while high TN concentrations in the sediment and pore water were observed mainly in the east portion of the lake. According to the enrichment factor index (an indicator evaluating the nutrient enrichment by comparing the detected contents and standard values), nutrients in the lake sediment were severely enriched with TN and TP averaging 2195.8 mg/kg and 543.0 mg/kg, respectively. The vertical distribution of TN and TP generally exhibited similar decreasing patterns with an increase in sediment depth, suggesting mineralization of TN and TP by microbes and benthic organisms. More attention and research are needed to understand the seasonality of nutrient exchange across the sediment–water interface, especially in eutrophic lakes.

The solution to the problem of feed protein deficiency is possible with an increase in acreage and the selection of agrotechnical methods of soybean cultivation, taking into account the conditions of the natural and climatic zone. One of the main elements of the farming system that allows to increase the yield of soybeans is rational basic tillage, its depth depending on the type of soil, providing favorable conditions for plant growth and development, which has not been studied in the northern forest-steppe in the Tyumen region. The purpose of the work was to study the influence of agrotechnical techniques on soybean productivity in the northern forest-steppe in the Tyumen region. During the research the influence of basic tillage and its depth on agrophysical (soil density, reserves of productive moisture), agrochemical soil parameters, uniformity of sowing depth, germination and preservation of soybean plants has been established. The contamination of crops, the species composition of weeds, and the degree of contamination during soybean cultivation by basic tillage with the use of herbicide during the growing season has been studied. It has been found that the highest level of profitability of 39,7 % was achieved with the differentiated method of tillage, with the mouldboard plowing (20–22 cm) it was less by 7,2 %, with the subsurface tillage (20–22 cm) it was less by 19,3 %. The decrease in the depth of processing leads to the decrease in the level of profitability by 4,0 % with the mouldboard plowing, by 2,2 % with the subsurface tillage and by 7,4 % with the diff erentiated method. With zero tillage, the profitability level was below control by 14,6 %. Thus, the most cost-effective was the differentiated method of tillage (20-22 cm) with the profitability level of 39,7 % and a profit of 9765 rubles/ha.

Published: January 2022

The development of beef cattle breeding and obtaining high-quality beef in Russia is currently one of the important tasks. The results of investigations on the influence of a feed additive with a low degree of protein breakdown on the efficiency of nitrogen use in the body of fattening steers and their productivity traits have been presented in the paper. The ration of steers included the feed additive as the source of hard-to-break down protein, which includes components of animal origin (feather fl our, fi sh meal, poultry waste), which have the high biological value of protein and its low degradation in the rumen. The feed additive was introduced into the daily ration at a dose of 1,5 g/kg of live weight. The accounting period of the experiment was 92 days. The degree of protein breakdown in the feed additive was determined on fistula animals in sacco, which was 55,2 %. The feed additive contains (%): 40–43 crude protein, 20–25 crude fat, 2,2 lysine, 1,9 methionine, 2,6 tryptophan, 1,5 calcium, 6,5 phosphorus. It has been found that the introduction of the protein additive with the low protein breakdown in the dose of 1,5 g/kg of live weight into the ration of steers had the positive influence on the indicators of the biochemical composition of blood, digestion in rumen, promoted better use of feed nitrogen and increased the productivity of fattening steers. There were significant differences in the increase in nitrogen deposition in the body of the experimental group of steerls by 29,5 %; the coefficients of nitrogen use from the feed consumed and from the digested increased by 5,57 and 7,71 abs.%, respectively. The average daily weight gain of the steers in the experimental group was 1102,17 g, which was 11,79 % higher compared to the animals of the control group that did not receive the protein additive. The research results indicate the effectiveness of the use of protein feed additive in the ration of young cattle during fattening.

Mitomaníaco: como lidar com crianças que mentem o tempo todo / Mythomaniacs: How to Deal with Children Who Lie All the Time
Authors: Rodrigues Fabiano de Abreu
Published: January 2022

Mentir é uma ação desenvolvida com o processo evolutivo cerebral do ser humano, deixando evidente que além da realidade em que vivemos, existe um mundo inacessível em todos nós. Este é utilizado quando existe uma necessidade de alcançar algum objetivo, como se ativado o modo de sobrevivência quando a região primitiva é acionada com medo de sentir as punições e/ou enfrentar as consequências das ações realizadas. Porém o ato de mentir demasiadamente faz com que forcemos o nosso cérebro a trabalhar de maneira inadequada, criando um ciclo vicioso devido sensação de recompensa liberada pelo neurotransmissor dopamina. Essa compulsividade altera significadamente a forma de nosso cérebro trabalhar e pode chegar num ponto onde a criança não consegue mais dizer a verdade e posteriormente, torna-se um adulto estrategista e frio, desencadeando desde cedo ansiedade, depressão e negatividade perante a própria vida. Tal acontece, pois, as sinapses são alteradas na região do córtex pré-frontal, criando essas anormalidades, precisando ser tratadas.

TanSat is China’s first greenhouse gases observing satellite. In recent years, substantial progresses have been achieved on retrieving column-averaged CO
2
dry air mole fraction (XCO
2
). However, relatively few attempts have been made to estimate terrestrial net ecosystem exchange (NEE) using TanSat XCO
2
retrievals. In this study, based on the GEOS-Chem 4D-Var data assimilation system, we infer the global NEE from April 2017 to March 2018 using TanSat XCO
2
. The inversion estimates global NEE at −3.46 PgC yr
-1
, evidently higher than prior estimate and giving rise to an improved estimate of global atmospheric CO
2
growth rate. Regionally, our inversion greatly increases the carbon uptakes in northern mid-to-high latitudes and significantly enhances the carbon releases in tropical and southern lands, especially in Africa and India peninsula. The increase of posterior sinks in northern lands is mainly attributed to the decreased carbon release during the nongrowing season, and the decrease of carbon uptakes in tropical and southern lands basically occurs throughout the year. Evaluations against independent CO
2
observations and comparison with previous estimates indicate that although the land sinks in the northern middle latitudes and southern temperate regions are improved to a certain extent, they are obviously overestimated in northern high latitudes and underestimated in tropical lands (mainly northern Africa), respectively. These results suggest that TanSat XCO
2
retrievals may have systematic negative biases in northern high latitudes and large positive biases over northern Africa, and further efforts are required to remove bias in these regions for better estimates of global and regional NEE.

Peristiwa makan adalah moment berharga bagi manusia. Makan bukan hanya peristiwa memasukkan makanan ke dalam mulut namun lebih dari itu peristiwa makan memiliki makna yang mendalam antara lain sebagai interaksi sosial dan identitas kultural. Makan adalah kegiatan sehari-hari yang selalu dilakukan manusia. Untuk bertahan hidup manusia harus makan. Seiring berjalannya waktu peristiwa makan bukan sekadar untuk mengenyangkan perut tapi juga suatu simbol untuk merayakan peristiwa penting. Bahkan dalam Kitab Suci banyak peristiwa iman yang ditandai dengan peristiwa makan. Peristiwa makan ini dimaknai sebagai moment perjumpaan kehidupan. Dalam tradisi Kristiani kita juga menemukan tradisi perjamuan ilahi yakni Ekaristi. Inti dari perayaan Ekaristi adalah ‘makan’ Tubuh dan Darah Kristus yakni yang disebut dengan Hosti dan Anggur. Segala bentuk aktivitas makan dalam kehidupan manusia dapat berdaya guna dan dapat membantu manusia memakani hidupnya dengan lebih mendalam. Untuk itu buah pemikiran dari teologi makan sangat dibutuhkan agar proses pencarian makna terdalam dari peristiwa makan pada kultur masa kini dan Ekaristi dapat ditemukan.

 

The occasion of eating is considered a precious moment for all people. Eating is not just a regime of putting food into the mouth, but rather than that, it is of deeper significance. Eating has means of social interaction and also of cultural identity. It is a day to day regular everyone committed to. In order to survive, humans are obliged to eat. As history went by, eating is not just an act of satiating the gut, but also marking significant events. In the Bible, numerous events of faith are celebrated through eating.

Facebook Post Data: A Primer for Educational Research
Authors: Borchers Conrad , Rosenberg Joshua , Swartzentruber Rita M.
Published: January 2022

Facebook is widely used and researched. However, though the data generated by educational technology tools and social media platforms other than Facebook have been used for research purposes, very little research has used Facebook posts as a data source—with most studies relying on self-report studies. While it has historically been impractical (or impossible) to use Facebook as a data source, the CrowdTangle platform allows academic researchers to freely access the massive collection of posts on public Facebook pages and groups. In this paper, we first outline how interactions and textual features in these public Facebook data in concert with established methods from educational data mining and learning analytics can be used to scrutinize educational discourse and knowledge sharing at scale. We then provide a primer that offers considerations for researchers before collecting these data (i.e., conducting research ethically and framing the study). The tutorial also covers matters directly pertaining to using CrowdTangle: accessing the CrowdTangle platform, uploading or identifying pages (or groups), and downloading historical data and it includes code using the statistical software and programming language R. We conclude with ideas for future directions for using Facebook posts as data with a focus on how educational researchers can leverage the scale of the available data and the time periods for which data is available to study educational affairs (i.e., issues or topics) and individuals (i.e., people or organizations) and to scrutinize how Facebook itself is used.

Assessment of the current residual capacity is a fundamentally important task, the solution of which is demonstrated on a landfill located in the Republic of Tatarstan. To solve the task, the modern methods of high-precision three-dimensional reconstruction were used based on the survey from an unmanned aircraft DJI Phantom 4, equipped with a global satellite navigation system (GNSS) receiver. As a result of combining the project data and data from field surveys into one coordinate system and elevations and reconstruction of designed underground and ground parts of landfill calculation, the difference of models and the residual capacity of the landfill becomes possible. Based on the materials considered as of July 2020, the residual capacity of the studied landfill is 41.2 % of the project capacity, which allows us to continue to operate this landfill. The proposed approach allows for rapid and high-quality active monitoring of the engineered facility. Photogrammetric processing of the results of low-altitude aerial photography makes it possible to obtain objective data on the current actual state of the landfills, to carry out competent and valid management of the landfill functioning. Significant, this will extend the landfill's lifetime, minimize the adverse effects on the environment and predict the yield to the project capacity much more accurately.

Published: January 2022

The article presents the results of a study of the climatic characteristics of the cold period in the city of Ufa of the Republic of Bashkortostan in the modern period. For the analysis, the authors used traditional processing methods. To identify climate changes, different base periods were considered (1961-1990, 1981-2010, 1991-2020). In some cases, time series of long-term observations were available only since 1973, so in these cases two base periods were distinguished. The statistical characteristics and changes in air temperature and its amplitude, the dates of the beginning/end and duration of the cold period, the amount of precipitation, relative humidity, the height of the snow cover and its moisture reserves, the dates of establishment/destruction and the duration of the snow cover are analyzed. Correlations between climatic indicators are shown. The study revealed that in all months of the cold period there is a tendency to increase air temperature, while the greatest contribution is made by an increase in minimum temperatures. A steady reduction in the duration of the cold period was found due to the shift of the start date to a later date, and the end date to an earlier one. The amount of precipitation tends to increase. Due to the reduction of the cold period, the duration of the snow cover in the city of Ufa decreases.

Broadband Performance Assessment of an RF Power Transistor Employing the Real Frequency Technique
Authors: yarman siddik
Published: January 2022

selected active device is essential to design an RF power amplifier for optimum gain and power added efficiency. As they are obtained, these impedances may not be realizable network functions over the desired frequency band to yield the input and the output matching networks for the amplifier. Therefore, in this paper, first, we introduce a new method to test if a given impedance is realizable. Then, a novel “Real Frequency Line Segment Technique” based numerical procedure is introduced to assess the gain-bandwidth limitations of the given source and load impedances, which in turn results in the ultimate RF-power intake/ delivering performance of the amplifier. During the numerical performance assessments process, a robust tool called “Virtual Gain Optimization” is presented. Finally, a new definition called “Power-Performance-Product” is introduced to measure the quality of an active device. Examples are presented to test the realizability of the given source/load pull data and to assess the gain-bandwidth limitations of the given source/load pull impedances for a 45W-GaN power transistor, namely “Cree CG2H40045”, over 0.8 -3.8 GHz bandwidth.

Published: January 2022

High voltage overhead transmission line route selection has become a vital component of the power transmission line project life cycle as demand for electricity has increased and global awareness of the environmental implications of large-scale power projects has grown. The project necessitates meticulous planning, engineering designs, facility installations, commissioning, and maintenance, as any errors made at this stage may have a flowing detrimental impact on the following phase, which may be too costly to fix. Using geographic information system (GIS), multi-criteria decision analysis approach, and environmental impact factors strategies, this study determines the best route from existing geographical space between Lafia 330/132/33kV Substation in Nasarawa State and New Apo (Pigba) 330/132/33/kV Substation in the Federal Capital Territory, Central Nigeria, Abuja. Land use, land cover, and other environmental data were obtained by performing image classification on Landsat 8 satellite image using ArcGIS 10.1 to achieve this goal. Three key terrain elements were identified to define the land cover types: built-up areas, vegetation, and water bodies. These layers were created to reveal the locations of significant settlements, geological formations, and the HV-OHTL route that avoided crossing protected areas. Using pair-wise comparison of analytic hierarchy process (AHP) approach, each criterion evaluated was assigned relative weight that shows their level of influence on the proposed power transmission line, and these were provided as GIS layers for visualizations. To build the cost surfaces assessed during route selection for HV-OHTL, weights derived from AHP method for each decision makers were applied to all layers to create the cost surfaces analyzed during route selection for HV-OHTL.

Fisiología de la tiroides e hipotiroidismo en el embarazo. Revisión de tema
Authors: Rueda-Galvis Myriam Vanessa , Builes-Barrera Carlos Alfonso
Published: January 2022

Durante el embarazo se generan múltiples cambios fisiológicos a nivel hormonal para llevar a cabo de manera satisfactoria la gestación. Uno de los ejes hormonales con cambios más importantes que repercuten de manera directa en el desarrollo fetal y bienestar materno es el tiroideo, el cual presenta modificaciones para lograr suplir las necesidades de hormona tiroidea tanto materna como fetal, principalmente en las primeras etapas del embarazo. Entre estas, se describen cambios en la cantidad de proteínas transportadoras de hormonas, aumento en el estímulo y producción de hormonas tiroideas, incremento del aclaramiento renal de yodo y alteración en la actividad de las desyodinasas. Estos mecanismos ofrecen suficiente hormona tiroidea al feto, el cual es dependiente del aporte materno. Un desajuste en cualquiera de estos mecanismos, puede conducir al desarrollo de hipotiroidismo con múltiples complicaciones, como la pérdida del embarazo e hipertensión gestacional, entre otras. Una tamización oportuna y un tratamiento temprano pueden evitar estos desenlaces adversos. De ahí la necesidad fundamental de conocer y comprender el comportamiento del eje tiroideo en la gestación.

COVID-19 es una enfermedad infecciosa respiratoria aguda, causada por el SARS-CoV-2, un nuevo coronavirus, que se extendió rápidamente por todo el mundo, dando como resultado una pandemia. Los pacientes presentan un amplio espectro de manifestaciones clínicas, entre ellas, la miocarditis, y de manera alterna, algunos pacientes sin síntomas de enfermedad cardíaca, tienen anomalías en las pruebas, como elevación de la troponina y arritmias cardíacas en el electrocardiograma, o anomalías en las imágenes cardíacas. La patogenia del compromiso miocárdico no es clara, pero las dos principales teorías prevén un papel directo de la enzima convertidora de angiotensina 2, que funciona como el receptor viral, y una respuesta hiperinmune, que también puede conducir a una presentación aislada. El estándar de oro del diagnóstico es la biopsia endomiocárdica, la cual no está disponible en la mayoría de los escenarios. En esta revisión, se pretende brindar al lector pautas para identificar las manifestaciones clínicas, ayudas diagnósticas y manejo de los pacientes con sospecha de miocarditis por COVID-19.

Resumo: A busca por uma carreira vitoriosa e de sucesso no futebol profissional é uma constância entre jovens e adolescentes. A competitividade para chegar ao alto rendimento, faz com que boa parte desses jogadores fiquem pelo caminho. O estudo teve como objetivo evidenciar os motivos de sucesso e insucesso na transição da carreira de futebol de base para o profissional entre o Brasil e Irã. Foi elaborado um questionário com questões fechadas, enviado via formulário no Google forms® para jogadores que atuam em categorias de base, ex-jogadores (categorias de base ou profissional), e atletas que atuam no futebol profissional atualmente. No Brasil os jogadores são mais dependentes dos alojamentos pelo motivo dos clubes brasileiros serem mais estruturados em relação ao Irã. Percebe-se que no Brasil por ter uma expansão territorial enorme, o distanciamento familiar é inevitável para os brasileiros. E também, a falta de oportunidades no ingresso aos clubes e na transição entre as categorias no Brasil, obtendo assim, resultados que demonstram os motivos do insucesso no futebol de campo para esses jovens atletas comparando os dois países citados. Sendo assim, com essa pesquisa concluímos que, as condições financeiras tanto dos clubes quanto dos atletas afetam na transição entre as categorias no Irã, já no Brasil a falta de oportunidades e o distanciamento familiar são fatores primordiais.

Perubahan iklim memiliki dampak bagi produksi garam dan rumah tangga petani garam. Penelitian ini dilakukan di Desa Donggobolo Kecamatan Woha, Kabupaten Bima pada bulan Agustus–September 2020 dengan melakukan penilaian terhadap penggunaan modal nafkah, tindakan resiliensi, serta adaptasi sebagai bentuk respons perubahan iklim. Hasil penelitian menunjukkan bahwa modal fisik merupakan modal utama yang digunakan oleh masyarakat pada sektor publik maupun privat. Keberadaan fasilitas dan lokasi desa yang dapat diakses dengan mudah menjadikan fasilitas fisik mudah dimanfaatkan dalam pemenuhan nafkah. Tindakan self-organization merupakan tindakan resiliensi dengan nilai tertinggi. Berbagai adaptasi juga dilakukan sesuai dengan fenomena iklim yang dihadapi seperti mengatur jumlah tenaga kerja di tambak garam, memberhentikan produksi, mencari alternatif nafkah, serta adaptasi teknologi. Jumlah petani garam menurun saat musim kemarau panjang dengan kemungkinan pemberhentian produksi dikarenakan musim kemarau panjang yang tidak diikuti musim hujan yang panjang sebelumnya akan menyebabkan kelimpahan stok garam dan penurunan harga. Alternatif nafkah menjadi prioritas apabila penghasilan pada saat musim garam yang tidak mencukupi. Pemanfaatan teknologi masih sedikit dilakukan karena sebagian besar pengadaannya bergantung pada pemerintah.
