Teacher Professional Development (TPD) is exponential for English teachers to the success of teaching and learning process in the classroom. Teachers with professional identity are deemed to have good quality in teaching. As stipulated by Rodgers & Scott (2008) teachers with professional identity are deemed to have good quality in teaching. The efforts to do this can be accomplished through such ways as participating  in conferences, seminars, workshops, and non-degree training, or even pursuing their further studies to master’ s degree and doctorate program. Also, they can conduct research and publish articles. This article is intended to provide evidence how novice, mid-career, and senior EFL teachers construct their identity professionally and autonomously. To arrive at the purpose of the study, an explorative survey was carried out to 129 EFL teachers throughout the Province of East Java via online questionnaire with 37 close-ended items. The findings revealed that (1) EFL teachers, be they junior, mid-career or senior ones involved in the present study, have tried to professionalize themselves via a number of corridors from self-directed ones to the ones imposed by other professional development providers; (2) teachers perceive their professional       status and areas in diverse ways, and (3) they have various professional and pedagogical knowledge and skills related to becoming professional EFL teachers. In conclusion, EFL novice, mid-career or senior teachers have manifested their professional identity with a number of corridors as professional autonomous learners.

Contemporary agricultural land use is highly impacted be the factors causing its degradation. That is particularly in evidence on those agricultural lands that are in the zone of risky farming with the conjoint exposure of the above factors. This zone includes the arid steppe of the Altai Krai occupying the area of more than 2,4 million hectares, which is of great importance concerning agriculture not only for the territorial subject of the Russian Federation, but also for the Siberian Federal District and the Russian Federation as a whole. To implement the priorities outlined in contemporary strategic regulatory documents and programs concerning the development of land resources, it is necessary to analyze them on a regular basis, identify natural and anthropogenic markers (restrictions) that affect their effective and rational implementation, as well as to model and manage the territory. In this paper assessment of the climatic, geobotanical and soil characteristics of the arid steppe territory of the Altai Krai has been taken, highlighting the features in municipal areas. An analysis of the use of agricultural lands in the dry steppe pointed out the irrationality of their use and the instability of the territory depending on various factors. Blowing has been found on absolutely all agricultural lands of the zone and is the main limiting factor on them. Therefore, the agroecological zoning of the territory, considered in this paper, and developed on the basis of the conducted agroecological assessment, systematizes the prospective effective use of agricultural land. Seven land groups and fifteen subgroups have been identified. Within the subgroups, classes, ranks, genera and subgroups have been outlined. While identifying agroecological groups of lands, the transformation of the land fund structure within administrative regions, the structure of cultivated areas and the system of crop rotation has been conducted. It is pointed out that measures of agricultural landscapes optimization will provide an increase in employment, the level of profitability per unit area, the increasing volume of natural capital, the increasing volume of agricultural production, while reducing the degree of development of blowing processes, thereby affecting the sustainability of agricultural land use.

The description and main characteristics of the deformation methods of the GGD field and GPS measurements used to assess the stress-strain state of seismically active mountainous areas of the Black Sea coast of Krasnodar Krai and Kamchatka are given. It has been established that the technology of the GGD field cannot guarantee the isolation of all recorded anomalies that are generated by the same source of the upcoming earthquake, and its practical use for the purposes of seismic forecasting remains limited. GPS measurement networks are a more technologically advanced and scientifically sound technology for monitoring seismic and geodynamic hazards. An example of using measurements in GPS networks and a multidimensional statistics algorithm to calculate an estimate of the integral criterion of the stress-strain state of the environment during the period of seismic activity in the Sochi area in 2017-2018 is shown.

An analysis of previously performed studies has shown that the coefficient of stability of the working sides of quarries and coal mines is considered constant along the open surface of the side or along its height. The method of limiting equilibrium for the entire sliding surface allows us to obtain an average value of the coefficient. The stress-strain state of the instrument array of the working side of a coal mine under the action of a distributed load from an external rock dump is investigated. The use of the finite element method and modern geomechanics software packages made it possible to obtain indicators of the stressstrain state and stability of the board at any point of the instrument array. The regularity of the change in the coefficient of the stability margin of the side according to its height is established. The lowest numerical value of the coefficient is characterized by the lower ledges of the side, the deformation of which leads to the weakening of the upper ledges and the possible manifestation of landslides.

The aim of the study is to analyze climatic changes within the arid landscapes of the North Caucasus using observational data from the reference meteorological network, as well as spatial interpretation of the results using GIS technologies. Materials and methods. To assess climatic changes in arid landscapes, data from the Divnoe, Roschchino, Naurskaya, Makhachkala and Derbent meteorological stations were used for the period from 1961 to 2020. Material processing was carried out using statistical methods (Exсel). The results were mapped using GIS technologies (MapInfo and ArcGIS). Results. Analysis of the thermal regime of the arid landscapes of the North Caucasus for the period from 1961 to 2020 showed that climatic changes proceed according to the scenario of an increase in annual air temperature. Precipitation in the north- and southwestern areas of semi-desert landscapes is decreasing, while in the southeastern areas it is increasing. Against the background of an increase in air temperature and a decrease in precipitation, the value of the hydrothermal coefficient is also decreasing. Thematic maps obtained from the analysis of the hydrothermal coefficient illustrate the increase in the area of semi-deserts and dry steppes in 2011-2015. In comparison with 1991 -1995. Conclusions. Despite the decrease in the hydrothermal coefficient for all areas of the semi-desert landscapes of the North Caucasus, the hydrothermal coefficient value remains within the limits typical for semi-deserts and dry steppes.

The growth in the power supply and the development of a mechanized complex of mining districts in coal mines has an impact on the characteristics of their power consumption. The improvement of coal mining technologies affects the servicing factor of mining machines, and the introduction of a modern variable-frequencyelectric drive can affect the dynamics of changes in electrical loads. Cited in the literature, the characteristics of the electrical load of the excavation districts of coal mines were obtained in the XX century and are outdated. To make adequate technical solutions in the design and management of power supply systems for coal mines, it is necessary to update these characteristics. Implementation of the SCADA system in coal mines makes it possible to obtain a large amount of measurement information that can be processed using modern methods of working with big data. The purpose of this work is a comparative analysis of the statistical characteristics of the electrical load of the modern Eickhoff SL 900 shearer with similar characteristics of the shearers used in the 1980s. The measurement data is collected using the SCADA system of a coal mine and includes measurements of the current, the shearer speed and the conveyor traffic flow. The measurement period covers 72 days. After the initial processing of the measurements, data arrays were formed with a time interval of 5 seconds. As a result of statistical processing of the arrays of measurements, the following characteristics of the shearer were determined: cycle time; work time; downtime; cyclic duration factor (CDF); time utilization degree (ηТ); coefficient of variation (CV). Comparative analysis of the listed characteristics showed that the SL 900 shearer has a significantly longer duration of operation and the time utilization degreein comparison with shearers of the 1960-1970s. Correlation analysis of the electrical load of the shearer with the shearer speed and the conveyor traffic flow showed a weak relationship, from which it was concluded that the dynamics of the change in the longwall shearer electrical load is mainly determined by the presence of solid inclusions in the destroyed coal mass.

The article describes a structured approach to the collection and verification of data on the process of blast borehole drilling in the formation of geostructural block models. When using methods and means of machine learning to create block models based on interpreted drilling data, an important aspect is the accuracy of the input data for the learning process compared with the geological and structural information about the rock mass. To identify the real response of drilling to the variation of rocks and the structure of the rock, the article provides comparison of data on the drilling process, data on specific energy intensity and data on the analysis of the changeability of the drilling in the rock when entering various geologic zones and fracture zones. To identify the real state of the rock, its variability and response of drilling data, a comparison of the slope of the ledge after the contour explosion is made in conjunction with the information on the specific energy consumption of the discontinent rows passed in blocks. The results of the endoscopic of the main explosive boreholes for the delay of telemetry data with comparison with the specific energy of drilling are presented. The analysis of the research obtained during the studies showed that the measurement system during drilling gives a real response to changes in array, such as breed transitions, the presence of fracture and disorders, etc. For a more accurate assessment of the nature of the appearance of jumps of values, it is possible to compare the specific consumption energy intensity of drilling and data behavior during MWD drilling.

Published: February 2022

The increase in the population creates prerequisites for the use of new undeveloped places, which include underground space. The development of underground space is associated with the construction of underground structures. A promising technology for the construction of underground structures is geokhodnaya. The basic element of which is a geokhod. As a rule, structures are built at shallow depths, which are characterized by rocks with a strength coefficient up to f = 1 on the scale of Professor M.M. Protodiakonov. Traditionally, the sinking of workings in these rocks is carried out by knife executive bodies. During the development and executive body design, one of the main indicators for evaluating its work is the energy intensity of the face rock destruction. As a result, a promising direction is to study the influence of the shape of the cutting edge of the knife executive body of the geokhod on the energy intensity of the destruction of the face rock. The article presents variants of schematic solutions of the geokhod knife executive body with a different shape of the knife cutting edge, developed on the basis of a functional and constructive approach to the development of constructive solutions and requirements for the geokhod executive bodies. It is established that the geokhod executive body geometric parameters, depending on the knife cutting edge shape, include: the angle of inclination of the knife with an inclined shape of the knife cutting edge; the radius of curvature of the knife cutting edge with a semi-convex and knife convex shape. The previously developed method of determining the face rock destruction energy intensity by the knife executive body of the geokhod is presented. For a promising direction of studying the influence of the geokhod knife executive body cutting edge shape on the energy intensity of the face rock destruction, the article provides initial data, which include the physical and mechanical properties of rocks and geokhod geometric parameters. As a result of the study, it was found that: the angle of inclination of the knife to the plane perpendicular to the axis of rotation does not significantly affect the face rock destruction energy intensity by the geokhod knife executive body; an increase in the knife cutting edge radius of curvature by the executive body of the geokhod leads to an increase in the energy intensity of the face rock destruction; given the physical and mechanical properties of the destroyed rock and the geometric parameters of the geokhod, it was found that with a knife cutting edge semi-convex shape and rкр = rг, the energy intensity of the face rock destruction is 1.4% less than with a straight shape. With a convex shape of the knife cutting edge and rкр = rг /2, the energy intensity face rock destruction is 8.3% less than with a straight shape.
SUBSTANTIATION OF THE NEED TO CREATE A NEW SCIENTIFIC DIRECTION – GEODYNAMICS OF UNDERGROUND APPARATUSES

The article presents the new basic functional systems of underground devices of the “geokhod” class, as well as the problems faced by developers at all stages of the creation of experimental and prototypes of the new class of underground devices “geokhod”. The development of systems of a new class of underwater vehicles is hindered by the lack of special scientific and methodological support. The authors of the article propose the creation of a new scientific specialty “Geodynamics of underground apparatuses”. The article presents the formula of the scientific specialty “Geodynamics of underground apparatuses”; priority tasks of the scientific specialty “ Geodynamics of underground apparatuses “, within which research is carried out and primaryresults are obtained. But so far, the state of scientific and methodological support in this area is a deterrent. The development of a new scientific direction “Geodynamics of underground apparatuses” will make it possible to fill this gap. Similarly, with the Aerodynamics of aircraft, and Geodynamics of underground vehicles as a science should include the basics of two main components: geodynamics and dynamics of movement of underground vehicles. Geodynamics of underground apparatuses should determine the forces and moments acting on underground apparatuses and on the basis of this determine the rational forms of interacting surfaces. It is noted that in all known definitions and problems of geodynamics there is no binding to the definition of the interaction of the machine and the geoenvironment. The concept of “geomedia” is defined by the example of geokhod mining. The geomedia is heterogeneous and anisotropic in its properties. When a solid body interacts with a medium, the formation of an interaction surface is inevitable. For the process of motion of a solid body in a solid medium, there are two real surfaces: the surface of a moving body and the surface of the medium, the shape and dimensions of which may not coincide, perhaps even often cannot coincide. By analogy with the aerodynamic shape, it is proposed to introduce the concept of “geodynamic shape”. To reduce the forces of resistance to the movement of the underground apparatus in the geomedia and to ensure its stability, it is important not only the rational external form of the underground apparatus and its systems, but also the rational form of the surface of the geo-environment – the Geodynamic shape of the surface. In conclusion, the main tasks of Geodynamics of underground apparatuses are formulated.

REGIONAL RETRIBUTIONS IN SPECIAL AUTONOMIC PROVINCE : A CASE STUDY OF EXECUTIVE REVIEWS OF LOCAL REGULATIONS
Authors: Hasan Sulaiman Badri , Abdullah Muslem
Published: February 2022

In the effort to implement special autonomy, various provinces in Indonesia are competing in the effort to increase the retribution of their respective regions. This has encouraged the provinces to make regulations (regulations) that can bring added value to their provinces. These regulations sometimes experience disharmony and out of sync with higher regulations, both in terms of the material and the technical aspects of their manufacture. This has resulted in an increasing number of local regulations being canceled or needing to be revised again after being tested by the Ministry of Home Affairs. To date, the Ministry of Home Affairs has evaluated at least 7500 local regulations from 2002 to June 2009, originating from all districts/cities and provinces in Indonesia. Of this number, almost half of the regional regulations were annulled because they contradicted the principles of the formation of local regulations. It is assumed that this number will continue to increase in line with the increasing legislative process in the regions.
Mechanical and biotic strategies for post-mine reclaimed grasslands

Published: February 2022

Global energy production is in high demand and is expanding its
development into new landscapes, including grasslands. This expansion
has intensive impacts on above and belowground components of grasslands
which need to be addressed during reclamation to promote long-term
ecological integrity. This study was conducted to ascertain how
alternative reclamation practices may improve soil structure (i.e.,
compaction) while aiding in the creation of conditions that are
conducive for both the establishment and continued growth of native
grassland plant species. The grassland was reclaimed with different
combinations of seeding mixtures (grass or grass and forb), ripping
techniques (subsoil ripping or topsoil ripping), and the integration of
mulch into the soil profile. Species composition and abundance of the
vegetation community was estimated, and volumetric soil moisture and
penetration resistance readings were obtained. Year, seed mixtures,
ripping techniques and their interactions significantly affected
community composition and species diversity. Topsoil-ripping and
grass-forb treatment had a higher association with native, perennial
grasses while subsoil-ripping and grass treatment favor more short-lived
species. Similar trends persisted across penetration resistance and soil
moisture readings where topsoil-ripping and grass-forb treatment were
different from subsoil-ripping and Grass treatments (p<0.10).
Additionally, Kentucky bluegrass, an invasive grass species, increased
76% over one year and was more common in the topsoil-ripping and
grass-forb treatments. While early in the reclamation process, results
suggest topsoil-ripping and grass-forb treatment are a promising
combination reclamation practice that can establish a native grassland
community and initiate the improvement of compacted soil conditions.

Authors: King Morgan , Stambulic Thomas , Payne Darrin , Fernandez Angel Luis , El-Diasty Mohammad
Published: February 2022

The use of sutureless and rapid-deployment prostheses is generally
avoided in patients with BAV due to anatomical concerns and the elevated
risk of para-prosthetic leaks. Multiple studies have reported the use of
these prostheses in patients with BAV with varying degrees of success.
The focus of this review is to consolidate the available evidence on
this topic. A scoping review was conducted using a comprehensive search
strategy within Medline, Embase, and Cochrane Central Register of
Controlled Clinical Trials for relevant articles. All abstracts and full
texts were screened by two independent reviewers according to predefined
inclusion and exclusion criteria. Of 1052 total citations, 44 underwent
full text review and 13 (4 case reports, 6 retrospective analyses, and 3
prospective analyses) were included in the scoping review. Across all 13
studies, a total of 314 patients with BAV were used for data analysis.
In sutureless and rapid-deployment prostheses, the mean postoperative
aortic valvular gradients were less than 15mmHg in all studies with mean
postoperative aortic valvular areas all greater than 1.3cm. There were
186 total complications for an overall rate of 59%. Individual
complications included new onset atrial fibrillation (n=65), required
pacemaker insertion (n=24), intraprosthetic aortic regurgitation (n=20),
new onset atrioventricular block (n=18), and new onset paravalvular
leakage (n=10). The use of sutureless and rapid deployment prostheses in
patients with BAV showed comparable intraoperative and implantation
success rates to patients without BAV. Various techniques have been
described to minimize complications in patients with BAV receiving
sutureless or rapid-deployment prostheses.

the exercise group where, starting from a not significantly higher
pulsatility index, it showed a continuous decrease during pregnancy to a
lower level than the non-exercise group, in which it remained unmodified
throughout pregnancy. Conclusion: A regular supervised mild-moderate
exercise program during pregnancy does not deteriorate fetal or maternal
Doppler, suggesting that fetal wellbeing is not compromised. UAPI
z-score decreases during pregnancy in the exercise group, while it
remains stable in the non-exercise group. Funding statement: Research

Organic materials are essential to increase soil organic carbon (SOC).
However, it is unclear whether C sequestration is primarily affected by
the form of organic materials or soil types. Wheat straw, tobacco straw,
and their derived biochars were added to acidic soil, saline soil and
calcareous soil in the same C concentration and incubated for 30, 90,
and 180 days, respectively. The contents of humic substances (HS), the
structural characteristic of SOC, and enzyme activities were
investigated. The results revealed that both biochar-C and crop straw-C
were mainly sequestered in humin (HU) across all soil types. Moreover,
humic acid (HA) levels increased in straw treatments but not in biochar
treatments. The cluster analysis and principal components analysis
showed that HU had a significantly positive correlation with SOC. The
aryl C of SOC increased in biochar treatments, while phenolic C and
O-alkyl C of SOC increased in straw treatments. A positive correlation
was found between aromatic C and SOC concentration, as well as between
polyphenol oxidase activity and O-alkyl C. The formation of O-alkyl C
was affected by polyphenol oxidase activity. These findings suggest that
the form of organic materials and microbial activity, rather than soil
types, influence the formation of HS and functional groups of SOC. Soil
amended with biochar can sequester more recalcitrant C while also
increasing the hydrophobicity of SOC.

Published: February 2022

This research paper is concerned with developing, analyzing, and
implementing an adaptive optimized one-step block Nyström method for
solving second-order initial value problems of ODEs and time-dependent
partial differential equations. The new technique is developed through a
collocation method with a new approach for selecting the collocation
points. An embedding-like procedure is used to estimate the error of the
proposed optimized method. The current approach has produced approximate
solutions to real-world oscillatory, periodic and stiff application
problems. The numerical experiments demonstrate that the introduced
error estimation and stepsize control strategy presented in this
manuscript has produced a good performance compared with some of the
other existing numerical methods.

Exploring highly active and stable electrocatalyst for oxygen evolution
reaction is important for the development of water splitting and
rechargeable metal-air batteries. Herein, a hybrid electrocatalyst of
CoFe alloy and CoxN heterojunction encapsulated and embedded in N-doped
carbon support (CoFe-CoxN@NC) was in situ coupling via a pyrolysis
process of a novel coordination polymer from lignin biomacromolecule.
CoFe-CoxN@NC exhibited an excellent OER activity with a low
overpotential of 270 mV at 10 mA•cm−2 and stability with increment of 20
mV, comparable to commercial Ir/C. DFT calculations revealed that CoxN
and N-doped grapheme encapsulation can reduce the binding strength
between *O and CoFe alloy, prevent metals leaching and agglomeration,
and improve electron transfer efficiency, thereby, remarkably enhancing
the OER activity and stability. In situ coupling strategy of alloy and
nitride heterojunction on N-doped lignin-derived carbon provided a
promising and universal catalyst design for the development of renewable
energy conversion technologies.
Defesa internacional contra as doenças epidémicas: Da visão de Jules Héricourt
Authors:   CIEP da Universidade de Évora, Bonito Jorge
Published: February 2022

As doenças epidémicas que assolaram as populações europeias vieram juntar-se às misérias já existentes até meados do século XIX, provocando consideráveis perdas de vidas humanas. O continente europeu tem uma longa história com a peste, doença causada pela bactéria Y. pestis. Ao contrário do que se possa pensar, a peste bubónica não é uma doença do passado. Continua presente em mais de uma dezena de países do mundo. Este artigo analisa as ideias de Jules Héricourt relativamente à transmissibilidade internacional das doenças epidémicas e o modo de mitigar as suas cadeias. Apoia-se, na essência, na sua obra Les Frontières de la Maladie, nomeadamente na Défense internationale contre las maladies épidémiques, et systémes quarantenaires. Em 1901, um surto de peste assolou os passageiros e a tripulação do navio Senegal, num cruzeiro no Mediterrâneo. Foi imposta uma quarentena a toda a tripulação e aos 174 passageiros no lazareto do arquipélago francês de Frioul. Registou-se uma morte. A falta de serviços mínimos e de medidas de desinfeção imediata dos passageiros e dos respetivos pertences poderia ter agudizado o problema. Héricourt, médico coautor da seroterapia, discorda dos métodos adotados pelas autoridades sanitárias, que seriam ilusórios na defesa internacional contra as doenças epidémicas. O autor propõe uma dupla solução prática e eficaz para o problema da transmissão das doenças exóticas nas viagens marítimas: a valorização do passe sanitário e a modificação do papel do médico de bordo. Todos os passageiros provenientes de territórios contaminados deveriam ser portadores do passe sanitário, sob rigoroso controlo das autoridades. Ao médico de bordo caber-lhe-ia constituir-se como verdadeiro agente da administração sanitária, como higienista, desmascarando potenciais doentes a partir de exames médicos durante a viagem e evitando que passageiros dados como sãos contaminassem a comunidade, por estarem efetivamente doentes.

A doença provocada pelo novo vírus SARS-CoV-2 (COVID-19) foi relatada pela primeira vez em dezembro de 2019, em Wuhan, China, e posteriormente disseminou-se por todo o mundo. A 2 de março de 2020, foram confirmados os primeiros dois casos de COVID-19 em território português, com a primeira morte a ser registada duas semanas depois, a 16 de março. Daí em diante, um conjunto alargado e variável de medidas sanitárias foram aplicadas, assim como a publicação de normas e orientações pela Direção-Geral da Saúde (DGS) e pela Autoridade Nacional do Medicamento e Produtos de Saúde, I.P. (INFARMED). Posteriormente, a 27 de dezembro de 2020, foi administrada a primeira vacina contra a COVID-19 (Comirnaty®; BioNTech Manufacturing GmbH/Pfizer), no Centro Hospitalar Universitário de São João, no Porto, marcando o início do plano de vacinação definido pela task-force e o envolvimento dos diversos profissionais de saúde. A Farmacovigilância das vacinas contra a COVID-19 constitui uma área de enorme importância, através da geração de evidência de mundo real sobre a segurança e efetividade pós-comercialização. Os Sistemas de Farmacovigilância têm a responsabilidade de rececionar, validar, analisar, solicitar dados adicionais, codificar e colaborar na imputação de causalidade de todas as suspeitas de reações adversas. Este artigo retrata a pandemia de COVID-19 em Portugal, no que concerne à sua evolução, plano de vacinação e atividades de Farmacovigilância. Adicionalmente, articula-se o tema com a realidade internacional, evidenciando-se as principais medidas, intervenientes e impacto na saúde pública.
Os Vírus são "singulares" e desafiam os paradigmas da Ciência
Authors:   Universidade do Porto, Faculdade de Ciências, Calafate Luís
Published: February 2022

A história do progresso do conhecimento científico dos vírus demonstra que a tendência dos investigadores para se prenderem a paradigmas e teorias específicas sobre as causas das doenças, não os deixa ver as ameaças de patógenos conhecidos e desconhecidos (Honigsbaum, 2021). É o caso, por exemplo, da “teoria dos germes” da doença, apresentada pelo bacteriologista alemão Robert Koch e o seu colega francês Louis Pasteur, na década de 1880. O paradigma bacteriológico da gripe humana, ao ser defendido por Richard Pfeiffer em 1892, atrasou durante décadas a compreensão da sua etiologia viral. Infelizmente, raro era o homem de ciência que ousava desafiar a autoridade de Koch e dos seus discípulos. Neste artigo pretendemos contribuir para a elaboração de uma imagem científica dos vírus, confrontando-a, sempre que necessário, com a ontologia da vida quotidiana. Para Dennett (2021), a imagem científica é algo que se tem de aprender na escola, e a maioria das pessoas adquire um conhecimento superficial da mesma. Não obstante, na nossa relação com os vírus, temos que aprender quais as “coisas” a retirar da nossa ontologia da vida quotidiana e quais as novas categorias a introduzir para criar uma ontologia da imagem científica dos vírus, fundamentando a nossa compreensão destas entidades singulares que desafiam os paradigmas científicos. É neste contexto que a abordagem do processo de produção do conhecimento científico tem sido apontada como de fundamental importância para compreender a Ciência, e a Virologia, como atividade humana historicamente contextualizada.
