Study of Material Flow and Mechanical Properties of Friction Stir Welded AA2024 with AA7075 Dissimilar Alloys using Top-Half-Threaded Pin Tool
Authors: Banjare Pragya Nandan , Dewangan Satya Kumar , Manoj Manoranjan Kumar
Published: October 2021

This research work was aimed at evaluating the material flow behavior and mechanical properties of dissimilar aluminum alloys (2024 and 7075) joints prepared by friction stir welding using a tool with top-half-threaded pin. Macro and microstructural study for material flow investigation was carried out. Whereas mechanical properties of welded joints are examined using tensile and micro-Vicker's hardness tests. Zeiss EVO 18 SEM was used for the fractographic study. Average grain sizes were determined at various weld regions. The effect of grain size with the hardness and strength has been discussed. The results demonstrate that the thread's location on the pin significantly affects the flow of the material. The area where the material has been severely plasticized and moved was located at the weld root. Hence welding root defects like void, pinhole, insufficient filling, etc. are avoided. The tensile strength of friction stir welded joint was 312.7 MPa, equivalent to the joint efficiency of 66.5 %.
HIGHLIGHTS

The threaded pin tool pushed the soft material downwards hence avoiding root defects.
The onion ring structure formation has been observed
The tool pin is responsible for creating two separate regions at weld line: Low flow region at the top and high flow region at central areas
The maximum tensile strength obtain is 312.7 MPa and 66.5 % joint efficiency

A partir de una reflexión en tomo a la historiografía clásica y reciente sobre el tema de los fastos públicos celebrados en los reinos pertenecientes a la Mo­narquía Hispánica así como sobre la recurrencia a programas emblemáticos para divulgar una teleología y conformar una política cohesionadora de los reinos, en este artículo me propongo apuntar algunas líneas de investigación que profundicen en la capacidad de articulación y en la problematización del uso de términos y categorías que se han venido utilizando prácticamente sin cuestionamiento alguno. Uno de esos términos es "barroco", no sólo en su acepción estilística o en tanto estructura histórica, como lo propone José An­tonio Maravall, sino como un adjetivo que merece ser replanteado en cada especificidad histórica y en cada entorno historiográfico.
La LOMLOE y sus controversias ante la ausencia de un pacto educativo en España
Authors: Novella-García Carlos , Cloquell-Lozano Alexis
Published: October 2021

Desde hace años, el sistema educativo español está sumergido en un aparente proceso de acuerdo social y político en el marco de la educación, cuyo pacto educativo proporcionaría un sistema estable, que al parecer no termina de germinar. En este artículo pretendemos reflexionar sobre el pacto educativo en España y la LOMLOE. Para ello, hemos analizado el debate social y político que ha suscitado la propia ley en todo su proceso, desde su propuesta en el Consejo de Ministros hasta su aprobación en el Congreso de los Diputados. Con una metodología cualitativa analítica, desde la hermenéutica crítica, hemos analizado los diarios de sesiones del Congreso y las 1.168 enmiendas presentadas. Asimismo, recogemos las valoraciones que los agentes sociales han realizado sobre la tramitación y aprobación de esta nueva ley educativa.

Published: October 2021

The space of scientific knowledge is understood as a system
of knowledge from various fields of science tested by the scientific community. The Common Digital Space of Scientific Knowledge (CDSSK) is a digital environment into which information resources and objects that
have been tested by the scientific community and that reflect scientific
knowledge from a different fields of science are integrated. The common digital space of scientific knowledge consists of a set of thematic subspaces related to various areas of science, built according to common principles. The first step towards the implementation of the CDSSK is the development of its
ontology, i.e. a multi-level system of concepts describing resources and objects of subject areas, concepts, terms and connections between them,
characterized by an open hierarchical and dynamic structuring, oriented both
for storing existing knowledge and for extracting new ones. Since the CDSSK
is a fundamentally new information environment, there are a number of
significant problems on the way to its implementation. The paper deals with
the problems and tasks of forming such a space and developing tools for
implementation and support the CDSSK

Automated System for Recording the Results of Scientific
Activity of Academic Institutions’ employees
Authors: Vlasova Svetlana
Published: October 2021

The article describes the automated system for creating and
maintaining a database for recording the results of scientific activities of
employees of academic institutions, developed by specialists of the Joint
Supercomputer Center RAS. The information base of the system contains
related data on the following classes of objects: persons (authors of
publications and reports), organizations and their subdivisions; publications
at analytical, monographic and summary levels; copyright certificates;
scientific events (conferences, symposia, seminars); reports. The system
reflects the sources of funding for scientific research, based on the results of
which the works were published, as well as the affiliations of each author
indicated in the articles. A distinctive feature of the system is the introduced
concept of “equivalent” objects. Objects are considered equivalent if they are
represented in the system by different metadata, but referring to the same
physical entity. Such objects are “persons” corresponding to the same author
with different spellings of the last name in the bibliographic descriptions of
publications; organizations with different versions of names; articles which
are published without changes in different languages. The system includes
two modules - administrative and user. The administrative module is intended
for entering and editing data. The user module of the system is a special search
engine that searches for information, visualizes it, navigates through related
resources and exports data.

Published: October 2021

Abstract. The three IASI instruments, launched in 2006, 2012, and 2018, are key instruments to weather forecasting, and most meteorological centers assimilate IASI nadir radiance data into atmospheric models to feed their forecasts. The EUropean organisation for the exploitation of METeorological SATellites (EUMETSAT) recently released a reprocessed homogeneous radiance record for the whole IASI observation period, from which thirteen years (2008–2020) of temperature profiles can be obtained. In this work, atmospheric temperatures at different altitudes are retrieved from IASI radiances measured in the carbon dioxide absorption bands (654–800 cm−1 and 2250–2400 cm−1) by selecting the channels that are the most sensitive to the temperature at different altitudes. We rely on an Artificial Neural Network (ANN) to retrieve atmospheric temperatures from a selected set of IASI radiances. We trained the ANN with IASI radiances as input and the European Centre for Medium-range Weather Forecasts (ECMWF) reanalysis version 5 (ERA5) as output. The retrieved temperatures were validated with ERA5, with in-situ radiosonde temperatures from the Analysed RadioSoundings Archive (ARSA) network and with EUMETSAT temperatures retrieved from IASI radiances using a different method. Between 750 and 7 hPa, where IASI is most sensitive to temperature, a good agreement is observed between the three datasets: the differences between IASI on one hand, and ERA5, ARSA or EUMETSAT on the other hand are usually less than 0.5 K at these altitudes. At 2 hPa, as the IASI sensitivity decreases, we found differences up to 2 K between IASI and the three validation datasets. We then computed atmospheric temperature linear trends from atmospheric temperatures between 750 and 2 hPa. We found that in the past thirteen years, there is a general warming trend of the troposphere, that is more important at the poles than at the equator (0.7 K/decade at the equator, 1 K/decade at the North Pole). The stratosphere is globally cooling on average, except at the South Pole as a result of the ozone layer recovery. The cooling is most pronounced in the equatorial upper stratosphere (−1 K/decade). This work shows that ANN can be a powerful and simple tool to retrieve IASI temperatures at different altitudes in the upper troposphere and in the stratosphere, allowing us to construct a homogeneous and consistent temperature data record adapted to trend analyis.
Recent decrease in summer precipitation over the Iberian Peninsula closely links to reduction of local moisture recycling

Published: October 2021

Abstract. The inherently dry summer climate of the Iberian Peninsula (IP) is undergoing drought exacerbated by more intense warming and reduced precipitation. Although many studies have studied changes in summer climate factors, it is still unclear how the changes in moisture contribution from the source lead to the decrease in summer precipitation. This study investigates the differences in the IP precipitationshed between 1980–1997 and 1998–2019 using the Water Accounting Model-2layers with ERA5 data, and assesses the role of local recycling and external moisture in reducing summer precipitation. Our findings indicate that the moisture contributions from the local IP, and from the west and the east of the precipitationshed contributed 1.7, 3.6 and 1.1 mm mon−1 less precipitation after 1997 than before 1997, accounting for 26 %, 57 % and 17 % of the main source supply reduction, respectively. The significant downward trend of the IP local recycling closely links to the disappearance of the wet years after 1997 as well as the decrease of local contribution in the dry years. Moreover, the feedback between the weakened local moisture recycling and the drier land surface can exacerbate the local moisture scarcity and summer drought.
Seasonal extrema of sea surface temperature in CMIP6 models
Authors: Wang Yanxin , Heywood Karen J. , Stevens David P. , Damerell Gillian M.
Published: October 2021

Abstract. CMIP6 model sea surface temperature (SST) seasonal extrema averaged over 1981–2010 are assessed against the World Ocean Atlas (WOA18) observational climatology. We propose a mask to identify and exclude regions of large differences between three commonly-used climatologies. The biases in SST seasonal extrema are largely consistent with the annual mean SST biases. However, the amplitude and spatial pattern of SST bias vary seasonally in the 20 CMIP6 models assessed. Large seasonal variations in the SST bias occur in eastern boundary upwelling regions, polar regions, the North Pacific and eastern equatorial Atlantic. These results demonstrate the importance of evaluating model performance not simply against annual mean properties. Models with greater vertical resolution in their ocean component typically demonstrate better representation of SST extrema, particularly seasonal maximum SST. No significant relationship with horizontal ocean model resolution is found.
Brief communication: Impact of common ice mask in surface mass balance estimates over the Antarctic ice sheet
Authors: Hansen Nicolaj , Simonsen Sebastian Bjerregaard , Boberg Fredrik , Kittel Christoph , Orr Andrew , Souverijns Niels , van Wessem Melchior , Mottram Ruth
Published: October 2021

Abstract. Regional climate models compute ice sheet surface mass balance (SMB) over a mask that defines the area covered by glacier ice, but ice masks have not been harmonised between models. Intercomparison studies of modelled SMB therefore use a common ice mask. The SMB in areas outside the common ice mask, which are typically coastal and high precipitation regions, are discarded. Ice mask differences change integrated SMB by between 40.5 to 140.6 Gt yr−1, (1.8 % to 6.0 % of ensemble mean SMB), equivalent to the entire Antarctic mass imbalance. We conclude there is a pressing need for a common ice mask protocol.
Large-scale snow data assimilation using a spatialized particle filter: recovering the spatial structure of the particles
Authors: Odry Jean , Boucher Marie-Amélie , Lachance-Cloutier Simon , Turcotte Richard , St-Louis Pierre-Yves
Published: October 2021

Abstract. The use of particle filters for data assimilation is increasingly popular because of its minimal assumptions. Nevertheless, implementing a particle filter over domains of large spatial dimensions remains challenging, as the number of required particles rises exponentially as domain size increases. A common solution to overcome this issue is to localize the particle filter and consider a collection of local applications rather than a single regional one. Although this solution can solve the dimensionality limit, it can also create some spatial discontinuity inside the particles. This issue can become even more problematic when additional data is assimilated. The purpose of this study is to test the possibility of remedying the spatial discontinuities of the particles by locally reordering the particles. We implement a spatialized particle filter to estimate the snow water equivalent (SWE) over a large territory in eastern Canada by assimilating local manual snow survey observations. We apply two reordering strategies based on 1) a simple ascending order sorting and 2) the Schaake Shuffle and evaluate their ability to maintain the spatial structure of the particles. To increase the amount of assimilated data, we investigate the inclusion of a second data set, in which SWE is indirectly estimated from snow depth. The two reordering solutions maintain the spatial structure of the individual particles throughout the winter season, which significantly reduces the random noise in the distribution of the particles and decreases the uncertainty associated with the estimation. The Schaake Shuffle proves to be a better tool for maintaining a realistic spatial structure for all particles, although we also found that sorting provides a simpler and satisfactory solution. The assimilation of the secondary data set improved SWE estimates in ungauged sites when compared with the open-loop model, but we noted no significant improvement when both snow courses and the SR50 data were assimilated.
A global analysis of the dry-dynamic forcing during cyclone growth and propagation
Authors: Besson Philippe , Fischer Luise J. , Schemm Sebastian , Sprenger Michael
Published: October 2021

Abstract. Mechanisms driving the intensification and propagation direction of extratropical cyclones are an active field of research. Dry-dynamic forcing factors have been established as fundamental drivers of the deepening and propagation of extratropical cyclones, but their climatological interplay, geographical distribution, and relatedness to the observed cyclone deepening and propagation direction remain unknown. This study considers two key dry-dynamic forcing factors, the Eady growth rate (EGR) and the upper-level induced quasi-geostrophic lifting (QGω), and relates them to the surface deepening rates and the propagation direction during the cyclones' growth phase. To this aim, a feature-based cyclone tracking is used, and the forcing environment is climatologically analysed based on ERA-Interim data. The interplay is visualized by means of a forcing histogram, which allows one to identify different combinations of EGR and QGω and their combined influence on the cyclone deepening (12 h sea-level pressure change) and propagation direction. The key results of the study are as follows. (i) The geographical locations of four different forcing categories, corresponding to cyclone growth in environments characterized by low QGω and low EGR (Q↓E↓), low QGω but high EGR (Q↓E↑), high QGω and low EGR (Q↑E↓), and high QGω and EGR (Q↑E↑), display distinct hot spots with only mild overlaps. For instance, cyclone growth in a Q↑E↑ forcing environment is found in the entrance regions of the North Pacific and Atlantic storm tracks. Category Q↓E↑ is typically found over continental North America, along the southern tip of Greenland, over parts of East Asia, and over the western North Pacific. In contrast, category Q↑E↓ dominates the subtropics. (ii) The four categories are associated with different stages of the cyclones' growth phase: large EGR forcing typically occurs earlier, during the growth phase at genesis, while large QGω forcing attains its maximum amplitude later towards maturity. (iii) Poleward cyclone propagation is strongest over the North Pacific and North Atlantic, and the poleward propagation tendency becomes more pronounced as the deepening rate gets larger. Zonal, or even equatorward, propagation on the other hand is characteristic for cyclones developing in the lee of mountain ranges, e.g. to the lee of the Rocky Mountains. The exact location of maximum QGω forcing relative to the surface cyclone centre is found to be a good indicator for the direction of propagation, while no information on the propagation direction can be inferred from the EGR. Ultimately, the strength of the poleward propagation and of the deepening is inherently connected to the two dry-dynamic forcing factors, which allow cyclone development in distinct environments to effectively be identified.
FUEL SUBSIDY REMOVAL AND THE NIGERIAN ECONOMY
Authors: Maria Chinecherem Uzonwanne , Regina Uju Ezenekwe , Paul Chinenye Iregbenu
Published: October 2021

Despite the huge amount of money Nigerian government spends on fuel subsidy, the situation in the oil sector has not been promising and Nigerians still experience scarcity of premium motor spirit. There have been dearth of infrastructural investments in the oil sector due to the enormous funds sunk into fuel subsidization, and as it is now, the government is yet to fix her refineries. As a result, there has been little or no significant improvement in the quality of life for the majority of Nigerians, 54 percent of who still lives below the national poverty line. Hence, the main objective of this study was to assess the contributions of the fuel subsidy in the Nigerian economy, that is, the study examined the problems, the prospects and a way forward for the sustainable economic growth in Nigeria. The study used Rosenstein-Rodan’s Thesis or Theory of the “Big Push” to drive home the message. The major sources of data used in the study were primary and secondary data. The primary data were collected through the use of questionnaire and the secondary data were also collected. Descriptive statistics was used to analyze the data. The study found that fuel subsidy has not resulted in a significant improvement in the quality of the life for the majority of Nigerians. The study therefore recommended that government should invest heavily on infrastructures and human capital instead of focusing on just removing fuel subsidy.

Notwithstanding the unstable nature of Nigeria economy small business owners created approximately 32 million jobs and contribute almost 45% to the nations GDP. However, startup small businesses fail at rate over 80% the first five years. Guide by theory of constraints, the purpose of this qualitative multiple-case study was to explore survival strategies required by some small business owners to sustain business in Nigeria beyond 5 years. Data collection was through semi-structured interviews with 3 owners with up to 5 years of experience in small business management from 3 different regions of Nigeria. The 3 major themes from final data analysis were cost efficiency, informal crediting and aggressive marketing which participants said were crucial for business survival. Data analysis also revealed two critical constraints confronted by small business owners as Government Policy and capital constraints. Findings of this study contribute to social change by indicating some strategies which prospective and existing small business practitioners may use to sustain for survival beyond first five years. The findings may prove useful for small business programs and training schedules to practitioners, managers and owners.

Published: October 2021

Este trabalho traz uma abordagem sobre processos socioeducativos e transição agroecológica. A base teórica se assenta nos autores Altieri (2012); Costabeber (2004); Machado (2014); Caporal (2008); Pacífico e SoGlio (2010). O Assentamento Terra Vista, em Arataca, Bahia, serviu de base empírica para os autores associarem as concepções teóricas, a partir das práticas dos agricultores assentados e assim analisar se os processos socioeducativos vivenciados pelas famílias assentadas são propulsores ou não da transição agroecológica. Portanto, partimos da hipótese que a transição agroecologia só é possível quando há a participação efetiva dos atores, por meio de processos socioeducativos. Neste sentido, uma agricultura de base ecológica requer a assimilação pelos atores sociais a apropriação dos instrumentos de sua realização, compreendendo a participação como a ferramenta principal dos processos sociais de mudanças. Neste sentido, os processos educativos são de fundamental importância, como ressalta Costabeber (1998) para a construção do conhecimento Agroecológico e assim efetivar a transição agroecológica. A experiência do Assentamento Terra Vista, vem demostrando, na prática a importância dos processos socioeducativos para a transição agroecológica.

Electronic Resources for Online Mathematics Primary Education – Specifics, Types, Quality
Authors:   Sofia University, Aleksieva Lyubka
Published: October 2021

This paper presents a theoretical research on electronic resources provided for mathematics education in primary school including online education, which has become ubiquitous as a result of the COVID-19 pandemic. Various aspects and forms of application of e-resources in mathematics education are explored in the literature, but the issue of their quality is less studied. E-resources potential to dynamically illustrate the mathematical learning content is defined as their main advantage, but this potential could be realized only in compliance with the principles of multimedia, as well as the requirements for accessibility, ergonomics and visual design. Therefore, in this study the parameters for the quality of e-resources for mathematics education in primary school are derived and specific criteria and requirements for their quality are proposed. Thus, in addition to providing a basis for future research, this paper could serve to primary teachers as a guide for measuring the quality of e-resources that they select or create for online mathematics education.

The main goal of this study was to construct an accurate classification model for the prediction of the antiproliferative activity against breast cancer cell lines of uredio-substituted sulfamates based on molecular structures alone and provide some insights into the structural features responsible for their activity. Partial least squares coupled with stepwise variable selection led to a statistically best significant model with coefficient of determination (r2) of 0.8396 and cross validated correlation coefficient (q2) of 0.7922. Design of novel uredio-substituted sulfamate molecules has been performed on the basis of chemical information obtained from descriptors of QSAR equations. The predictive accuracy of models, together with the identification of important contributions in QSAR and classification models, offer the possibility of designing potent selective inhibitors and estimating their activity prior to synthesis.

Lisinopril is used in the treatment of hypertension and heart failure in myocardial infarction and also in diabetic nephropathy. It is very poorly absorbed from GIT. Intranasal administration is an ideal alternative to the parenteral route for systemic drug delivery. Formulating multiparticulate system with mucoadhesive polymers may provide a significant increase in the nasal residence time. The microspheres prepared by emulsion solvent evaporation method were characterized for encapsulation efficiency, drug loading, particle size, surface morphology, degree of swelling, ex vivo mucoadhesion, drug release and ex vivo diffusion studies. Entrapment efficiency of microspheres was in range of 84.95±0.50% to 97.44±0.61% mucoadhesion was 83.76% and 94.41% and drug release up to 40 minutes was 53.66% to 88.32%. In ex vivo studies, the microspheres showed good bioavailability by nasal route compared to oral drug administration. Both in vitro and in vivo studies conclude that combination of Carbopol and HPMC based microspheres are better than single carbopol-based formulation for the delivery of lisinopril.

Upper respiratory tract infections (URTIs) are illnesses caused by an acute infection which involves the upper respiratory tract: nose, sinuses, pharynx or larynx. Roxithromycin (macrolide antibiotic) and ambroxol HCl (mucolytic) are used for this treatment. The dual release system of roxythromycin and ambroxol HCl was successfully prepared by bi-layer tablet approach for management of URTI. Quick release of roxithromycin was achieved by using disintegrants and slow release of ambroxol HCl was achieved by using matrix formulation of drug with HPMC K4M and ethyl cellulose. The 32 full factorial design was adopted for optimization of polymer concentration to achieve identical drug release with theoretical dissolution profile. The amount of HPMC K4M and ethyl cellulose were selected as independent variable and the similarity factor with theoretical dissolution profile and percentage drug release at 10th hr was selected as dependent variables. The prepared dual release tablets were evaluated for physical parameters, drug content, in vitro drug release study, etc. All the parameters were found to be acceptable in range. As the concentration of HPMC K4M is increased, the drug release decreases and the effect of ethyl cellulose was found to be less compared to HPMC K4M.
