A comparative corpus stylistic analysis of thematization and characterization in Gordimer’s My Son’s Story and Coetzee’s Disgrace
Authors: Moustafa Basant S. M.
Published: March 2022

My Son’s Story and Disgrace are two novels written by two South African Noble laureates – Nadine Gordimer and J. M. Coetzee, respectively. The current study attempts to comparatively uncover the thematic foci as well as characterization aspects and interpersonal relations between characters in the two novels by dint of corpus linguistic tools, i.e., keywords and key clusters. Thus, using Sketch Engine online interface, the study presents a comparative thematic categorization of the two novels – a categorization which proves congruent with the thematization provided by previous critical literary studies of each novel. Both novels are found to revolve around racial tensions and illicit relationships in South Africa. However, although My Son’s Story is set during the apartheid and Disgrace is set after the apartheid is supposedly over, comparative corpus-driven investigation of the two novels reveals that the South Africa promised in My Son’s Story is betrayed in Disgrace, since racial violence and cross-race sexual dissipation persist. Quantitatively, using the notion of local textual functions, the associations between the use of key clusters, their repercussions on characters’ depiction, and their interpersonal relationships are uncovered. Clear affinities between the two protagonists, Sonny and David, are discerned, e.g., their love for music and literature, their sexual whims, their unsettled relationships with their children, etc. Empirically, the father–son/daughter turbulences, husband–wife vicissitudes, landlord–farmer intricacies, and love affairs’ intricacies are fathomed.

Published: March 2022

In this research paper, the authors aim to establish a novel algorithm in the finite difference method (FDM). The novel idea is proposed in the mesh generation process, the process to generate random grids. The FDM over a randomly generated grid enables fast convergence and improves the accuracy of the solution for a given problem; it also enhances the quality of precision by minimizing the error. The FDM involves uniform grids, which are commonly used in solving the partial differential equation (PDE) and the fractional partial differential equation. However, it requires a higher number of iterations to reach convergence. In addition, there is still no definite principle for the discretization of the model to generate the mesh. The newly proposed method, which is the SM method, employed randomly generated grids for mesh generation. This method is compared with the uniform grid method to check the validity and potential in minimizing the computational time and error. The comparative study is conducted for the first time by generating meshes of different cell sizes,i.e.,10×10,20×20,30×30,40×4010\times 10,\hspace{.25em}20\times 20,\hspace{.25em}30\times 30,\hspace{.25em}40\times 40using MATLAB and ANSYS programs. The two-dimensional PDEs are solved over uniform and random grids. A significant reduction in the computational time is also noticed. Thus, this method is recommended to be used in solving the PDEs.

Published: March 2022

Soft polymers such as polyether ether ketone (PEEK), polyurethane (PU) and polytetrafluoroethylene (PTFE) have gained significant research interest in the last few decades owing to their excellent material properties which can be harnessed to meet the demands of various applications such as biomedical implants and accessories, insulation panels to cooking utensils, inner coating material for non-stick cookware etc. In the present study, we provide a comprehensive review on the mechanical and tribological behaviour of PEEK, PU and PTFE polymers. Samples of these materials were also fabricated and the experimentally obtained tensile strength, flexural strength, wear rate and coefficient of frictions were ascertained with values reported in literature. It is highlighted that coefficient of friction of polymers were highly dependent on the surface texture of the polymer’s surface; where an uneven surface exhibited higher coefficient of friction. Perspectives for future progress are also highlighted in this paper.
mRNA editing of kainate receptor subunits: what do we know so far?
Authors: Gaidin Sergei G. , Kosenkov Artem M.
Published: March 2022

Kainate receptors (KARs) are considered one of the key modulators of synaptic activity in the mammalian central nervous system. These receptors were discovered more than 30 years ago, but their role in brain functioning remains unclear due to some peculiarities. One such feature of these receptors is the editing of pre-mRNAs encoding GluK1 and GluK2 subunits. Despite the long history of studying this phenomenon, numerous questions remain unanswered. This review summarizes the current data about the mechanism and role of pre-mRNA editing of KAR subunits in the mammalian brain and proposes a perspective of future investigations.
Doped TiO2slabs for water splitting: a DFT study
Authors: Khan Muhammad Isa , Khan Wahid Ullah , Majid Abdul
Published: March 2022

The realization of water splitting at a commercial scale is one of the major obstacles to the development of a viable and long-term hydrogen economy. In this regard 3d-transition metals (TMs) doped anatase TiO2slabs are investigated to understand the role of magnetism in water splitting using density functional theory (DFT). The structural stability of various 3d-TMs (V, Cr, Mn, Fe, Co, Ni, and Cu) doped in TiO2ultrathin films have been investigated. The electronic band structures show that the doping of 3d-TMs makes the bandgap of TiO2narrow which leads to the improvement of photo-reactivity as well as maintains the strong redox potential. The large magnetic moment of Fe- and Mn-doped slabs indicates that high charge transfer to water molecules with low adsorption energy. The results demonstrate that V, Fe, and Co doping makes the slabs ferromagnetic (FM), whereas Cr, Mn, Ni, and Cu doping makes the slabs non-magnetic. The water molecule is placed on each FM slab and their splitting behavior has been analyzed thoroughly. It was concluded that magnetism does not affect water splitting.
Courage and Fear: Weathering the Collective Racial Storm
Authors: Brewster Fanny
Published: March 2022

During the past 2 years our American collective has seen a return to political demonstrations and increased activities towards a deepening consciousness related to raciality. This article asks that we look at racism within the contexts of our collective American psychology and our personhood. This perspective considers Jungian psychology and its influences on the development of this form of psychoanalysis in America. Is this the work of psychology—to increase understanding and compassion among individuals of different ethnicities? The article explores the grievous and grief that is a necessary aspect of racial suffering for individuals of color. The individuation that Jungian psychology oftentimes references can be applied to the individual personhood of those within an Africanist cultural group. Discussion in the article acknowledges this inclusion as well as the idea of furthering a consciousness of Africanist people as valued members of American society.
Soft Power Polls and the Fate of Liberal Democracy
Authors: Nisbett Melissa , Rofe J. Simon
Published: March 2022

Since entering mainstream discourse, the term “soft power” has become more popular than ever. The last ten years has seen the emergence of a number of international polls that rank countries based on their soft power. These rankings have not just coincided with the rise in significance of soft power; they have actively shaped how the term is used and understood. Yet they remain unexamined. This article critically analyzes two of these polls: the Monocle Soft Power Survey and the Portland Soft Power 30 Ranking. While the analysis reveals substantial methodological flaws, this article ultimately concludes that these flaws are irrelevant. The polls neglect the broader context within which they sit and only partially engage with. Further, the polls overstate the primacy of the Western liberal order, while underplaying a creeping authoritarian threat at a time when liberal democracy is in peril. What is more, by recognizing and even celebrating the soft power gains of autocratic regimes, the polls give exposure and airtime to tyrants and autocracies, thereby legitimating them both domestically and overseas. The polls therefore demonstrate, inadvertently, that soft power has relevance beyond the West but do not recognize that it can be used strategically against the West for geopolitical gain. These polls have real-world consequences in shaping soft power at a time of both growing authoritarianism and liberal retreat, and, as such, they are implicated in the future and fate of Western democracy.

Authors: Li Bin , Liu Aijun , Yang Ming , Su Junwu , Fan Xiangming
Published: March 2022

Background: There are few surgical treatment results in elderly patients with functional single ventricle (FSV) and total anomalous pulmonary venous connection (TAPVC). We retrospectively analyzed 10 years of mid-term surgical treatment results and risk factors of these age-specific people.
Methods: Between March 2008 and December 2018, 43 consecutive patients with FSV and TAPVC received initial surgical palliation in our center. There were 20 cases of supracardiac TAPVC, 21 of cardiac type, and two cases of mixed type. Initial surgical palliation procedures involved pulmonary artery banding (PAB) for patients, modified Blalock-Taussing shunt (mBTs) for five patients, and bidirectional Glenn (BDG) for 34 patients. TAPVC repair was performed in 12 patients during BDG.
Results: The 1-year and 5-year overall survival rates were 69.7% and 62.8%, respectively. In TAPVC repair group and non-TAPVC repair group, the 1-year overall survival rates after initial surgical palliation were 41.7 and 80.5%, respectively, and the 3-year ones were 25% and 77%, respectively. There were significant differences in the type of TAPVC (P < 0.001), preoperative pulmonary venous obstruction (P = 0.001), and overall mortality (P = 0.001) between these two groups. Cox univariate and multivariable analysis indicated concomitant TAPVC repair was the only risk factor for mortality.
Conclusions: The mid-term results of surgical treatment of FSV and TAPVC, especially for patients who underwent concomitant TAPVC repair, remain poor. TAPVC repair may be a priority over single-ventricular palliative surgery for patients with FSV and TAPVC.

Published: March 2022

Se determinó el efecto de la glutamina y del ácido glutámico adicionados a la dieta de cuyes (Cavia porcellus) sobre la estructura intestinal y la actividad de las enzimas digestivas, así como sobre el comportamiento productivo y económico. Se utilizaron 100 cuyes de ambos sexos, de 15 días de edad, con peso inicial de 358.8 + 27.5 g en dos fases (Inicial de 15 a 32 días y de crecimiento de 33 a 74 días de edad). Se incluyó en la dieta cuatro niveles del producto comercial AminoGut® (0, 0.025, 0.050 y 0.075%) a través de un diseño completo al azar con cuatro repeticiones. Se observó una mejor ganancia de peso y conversión alimenticia en la fase de inicio a través de un comportamiento cuadrático (p<0.05), con mejor respuesta en el nivel de 0.056% de inclusión; sin embargo, no hubo efecto significativo en la fase de crecimiento ni en el global. En la estructura intestinal, en el día 5 del destete, se observó criptas más profundas con mayores niveles de inclusión, pero sin afectar la relación vellosidad/cripta. Asimismo, la actividad de la enzima maltasa mostró un comportamiento cuadrático (p<0.05) con mayor actividad en el nivel estimado de 0.048% de AminoGut® en la dieta, aunque no hubo efecto en el día 8 posdestete. El beneficio económico y la rentabilidad fueron mayores en los tratamientos que recibieron mayores niveles de inclusión. Se concluye que la suplementación de glutamina y ácido glutámico fue satisfactoria para el desempeño productivo y económico de los cuyes, dando mejores respuestas con los mayores niveles utilizados en la dieta.

El estudio tuvo como objetivo conocer el nivel de empatía humano-animal y humano-humano, y la percepción de bienestar animal en estudiantes de profesiones relacionadas al uso, manejo y cuidado animal de instituciones mexicanas de educación superior. Se aplicó un cuestionario electrónico (Google Fomularios) donde se incluyó la Escala de Empatía de Paul (22 ítems) para medir el nivel de empatía humano-animal; el Índice de Reactividad Interpersonal (27 ítems) para medir la empatía humano-humano y el cuestionario para la medición de actitudes hacia el maltrato animal como indicador de percepción de bienestar animal (14 ítems). En total, 1688 encuestas procedentes de 35 instituciones fueron contestadas. Los resultados muestran que las mujeres tuvieron puntajes significativamente mayores que los estudiantes varones en la empatía humano-animal, humano-humano y percepción de bienestar animal. Hubo una reducción de la empatía humano-animal a partir del segundo año de la formación universitaria en varones y del tercer año en mujeres. Estudiantes con preferencia hacia la producción animal mostraron valores de empatía humano-animal y percepción del bienestar animal más bajas. Se considera necesario la introducción de contenidos en los planes de estudio para desarrollar habilidades de empatía hacia los animales desde el inicio y durante toda la formación profesional.

Se analizaron datos en un periodo de dos años de 932 corderos de una granja. El modelo estadístico incluyó los efectos fijos del peso al destete (<11, 12-14, 15-17, >18 kg), el año (2012 y 2013), la época del año (lluvias, secas y nortes) y las interacciones simples significativas del año × la época del año y el error residual, NID (0, σ2e) sobre la ganancia diaria de peso posdestete (GDP, g/d), el peso final (PF, kg) y el periodo de engorda (PE, días). El peso al destete afectó todas las variables de respuesta evaluadas (p<0.05). Los corderos destetados entre los 12-14, 15-17 y >18 kg, tuvieron una GDP similar, y a su vez obtuvieron una mayor GDP que los corderos destetados con menor peso (<11 kg; p<0.05). El PF fue similar para los corderos destetados con 15-17 y >18 kg, superior al obtenido por los corderos destetados a los <11 kg (p<0.05). El PE fue diferente (p<0.05) para cada grupo de peso al destete, siendo mayor para los de menor peso al destete. En conclusión, el peso al destete es un factor que afecta la GDP, PF y PE de corderos en corrales elevados.

EASTER SHORT STORIES BY A. I. KUPRIN
Authors: Zhirkova Marina
Published: March 2022

Easter motifs permeate all of Kuprin's work and reflect the trends characteristic of the development of the Easter genre in Russian literature as a whole. Early short stories point to the crisis of the genre: “Bonze” contradicts the Easter canon; irony appears in the short stories “By order”, “My passport”, “Family style”, “Grass.” They contain mandatory elements of the genre: are timed to Easter, possess a special festive mood, tenderness and emotion, and display a spiritual renewal of the characters. In some of the short stories written in 1911–1916 (“Easter Eggs”, “Holy Lies”, “Daddy”) a comic component appears: satire intensifies, and irony turns into sarcasm. Traditional Easter plots seem banal, and therefore fake and feigned, resembling a parody of the genre. In exile, the writer again turns to the Easter genre: he writes “Moscow Easter” and “Easter Bells.” The author himself craves the enlightenment and transformation that Easter brings, creativity becomes salvation, bringing light and joy to the writer who is longing far from his homeland. Memories of childhood or youth become the basis of most Easter story plots. After all, a naive and sincere belief in miracles persists in children for a long time, they very keenly experience the joy that this holiday brings with it, while adults eventually lose this childish faith in miracles, and their life-drained, hardened souls become cold and still. Memories can be different, they are not always joyful or happy, but it is the experience of these memories, the immersion in the past that creates a special festive mood and promotes spiritual purification and transformation.

The properties of heteropoly acids and of their complexes with cationic surfactants at the trace level have been studied by ESR spectroscopy, UV-VIS spectrophotometry, NMR and FTIR spectroscopy, by the method of chemiluminescence analysis applied in aqueous solutions and on the cellulose surface. For elucidation of the mechanism of chemiluminescence reactions of heteropoly acids with luminol kinetic methods, diffuse reflectance spectroscopy and liquid chromatography have been applied. For the first time one-electron reduction of heteropoly acids by luminol was confirmed by registration of diffuse reflectance spectra of reduced heteropoly acids on cellulose surface. It has been suggested that the mechanism of heteropoly acids immobilization on cellulose includes combination of Coulomb and hydrophobic interactions. A scheme of heteropoly acids immobilization on the surface was proposed based on ion exchange processes on cellulose or diethylaminoethyl cellulose surface. It has been shown that ionic associates heteropoly acid – cationic surfactant react with an alkaline solution of luminol with light emission similarly to heteropoly acids themselves. For the first time, heterogeneous chemiluminescence, namely, the chemiluminescence of heteropoly acids immobilized on cellulose, with luminol, has been used for examining the composition of ionic associates heteropoly acid - cationic surfactant. By using Bjerrum’s method it has been found that in strongly acidic media (at pH 1.0) vanadomolybdophosphoric acid forms with cationic surfactant, namely, with dodecylpyridinium bromide, not tetra-substituted but triply substituted ionic associate. This result can be explained by the fact that the fourth proton in H4PVMo11O40 is weakly dissociated; it is more strongly bound to heteropoly anion and is localized on the oxygen atom of the Mo–O–Mo angular bond. Ionic associates of heteropoly acids were used as analytical forms for highly sensitive chemiluminescence determination of P, As, Si, Ge in waters of different types. Detection limits for P, As, Si, Ge are 0.02–0.07 µg/L. Due to the high sensitivity of the method, phosphorus was successfully determined in surface water and ultrapure water, arsenic – in river and mineral water, silicon – in ultrapure water and vapor condensate of electric power stations, germanium – in water of electronic industry.
Defining Developmental-Behavioral Pediatrics

Published: March 2022

There is an insufficient number of specialty developmental-behavioral pediatrics (DBP) physicians, despite nearly 25% of children and adolescents having a developmental, learning, behavioral, or emotional problem. In the nearly 20 years since becoming a board-certified subspecialty, the definition of DBP clinical practice remains somewhat unclear. This lack of clarity likely contributes to recruitment challenges and workforce issues, and limited visibility of DBP among parents, other professionals, payors, and administrators. Defining DBP is therefore an important step in the survival and growth of the field. In this paper, we describe the methodology used to develop this definition along with the origins of DBP, the persistent challenges to defining its scope, what training in DBP involves, and what distinguishes DBP from other overlapping fields of medicine. We propose the following definition of DBP: developmental-behavioral pediatrics (DBP) is a board-certified, medical subspecialty that cares for children with complex and severe DBP problems by recognizing the multifaceted influences on the development and behavior of children and addressing them through systems-based practice and a neurodevelopmental, strength-based approach that optimizes functioning. Developmental behavioral pediatricians care for children from birth through young adulthood along a continuum including those suspected of, at risk for, or known to have developmental and behavioral disorders.
Tongue rolling stereotypy in cattle – etiological, epidemiological and clinical investigations
Authors: Binev R.
Published: March 2022

The present studies were carried out to establish the causes for appearance, prevalence, age- and sex-related features, the frequency and 24-hour pattern of clinical signs accompanying the tongue rolling stereotypy in cattle. The animals were distributed in 2 groups: group I (n=1055) – control animals that did not demonstrate the tongue play orosthenic syndrome and group II (n=48) – cattle manifesting this stereotypy. Both groups were uniform with regard to age, breed, body condition and sex. They were placed under equal housing conditions (animal hygiene parameters, feed quantity and quality) and activity regimens (walks, feeding etc.). It was found out that the causes for demonstration of the tongue rolling hyperactivity in cattle were the deprivation from food and boredom, due to deficiency of environmental stimuli. The studied stereotypy was observed in cattle in different age groups – suckling and weaned calves, as well as heifers, including pregnant ones. The tongue play activity was no longer exhibited by heifers after calving and moving into the basic herd of lactating cows. The highest intensity (up to 80%) of this orosthenic syndrome was manifested before the morning feeding, between 9.00 and 12.00 AM. Most commonly, the tongue rolling activity was found out in heifers between 13 to 25 months of age. The studied oral stereotypy was not accompanied with changes in measured clinical parameters – rectal body temperature, pulse and respiratory rates, rumen movements, as well as in other activities e.g. rumination, eructation, appetite, sentience, locomotion etc.
Willingness to persist
Authors: Whited Jennifer , Damico Jack S.
Published: March 2022

Purpose: This qualitative investigation studied children with language disorders engaged in remediation for literacy impairment. Specifically, we studied behavioral interactions between the speech-language pathology students and children when providing literacy intervention. Based on the study results, this article proposes a positive, strengths-based view of avoidance behaviors that re-frames avoidance behaviors used by children as compared to a traditional, deficit-based view. Method: Qualitative methods were employed; specifically, interactional analysis, a process derived from conversation analysis, was employed to analyze video transcripts of children engaged in remediation of literacy impairment. Results and conclusions: This study revealed six types of avoidance behaviors signaling a willingness to persist rather than a desire to quit. These avoidance behaviors include shadowing, delaying, making sound effects, producing related comments, and producing unrelated comments or questions. These behaviors indicate that these children remained engaged in the therapeutic contract, even though they avoided reading. This research indicates a shift in therapeutic perspective. We should view avoidance behaviors not as negative behavior to suppress, but rather as a sign of willingness to persist in the activity. In addition, these findings suggest that avoidance behaviors are signals for increased therapeutic support and shifts in instructional direction. The results suggest that even potentially problematic behaviors, if focused on engaging in the social action at hand, are a sign of motivation to read.
The Dimensions of Territorial Embeddedness of the Business Services Sector in Central and Eastern Europe
Authors: Geodecki Tomasz
Published: March 2022

Objective: The purpose of this article is, first, to propose a range of measures of territorial embeddedness in order to describe the phenomenon in question, and, second, to use the se measures to determine the level and dynamics of the embeddedness of the Business Services Sector (BSS) in Central and Eastern European (CEE) economies.
Research design & Methods: In the debate about the future of the BSS in these low-cost economies, two challenges have been identified. The first one involves the threat of relocation. The other one is associated with linkages between service companies and local customers/suppliers weaker than that of in Western Europe. These two challenges can be addressed by tackling the third one, namely the increasing of process efficiency. In consequence, even an increased share of foreign contractors does not have to reduce the scale of cooperation with local entities. In the empirical part of this paper, changes in these three areas that make up territorial embeddedness are explored in depth. Eight divisions covering the BSS in the CEE-11 countries were compared with their Western European counterparts (the EU-17) at two points in time, i.e. in 2000 and in 2014. The study relies on basic statistical data and calculations with the use of the World Input-Output Tables.
Findings: It was found that due to productivity growth, the cost competitiveness of the BSS in CEE countries was
maintained in the period of interest. Moreover, despite the growing internationalisation of the sector, the scale
of cooperation of the BSS with local actors has increased. The rapidly improving skills of employees in the Central European BSS – as well as the growing importance of knowledge-intensive services (KIS) in the structure of value added – can further contribute to the importance of CEE as a location for business services in Europe.
Implications/Recommendations: The studied period saw an improvement in the structure of value added, as an increasing share of it was accounted for by knowledge-based services. This implies a high probability of further productivity growth of the BSS in CEE, and bodes well for the degree of territorial embeddedness both in terms of decreasing the likelihood of relocation and amplifying the capacity of local actors to act as the suppliers and the recipients of state-of-the-art services.
Contribution/Value Added: I have recognised that when service provision is subject to massive offshoring, it is not so much the intensity of service provision (exports) as the intensity of value added creation in the local economy that is of significance. Moreover, the relative gains in this respect should determine the scale of territorial embeddedness, the competitiveness of individual sectors, as well as their growth prospects.

Objective: To demonstrate how a high-skilled competitively-priced Polish labour force, thriving amid enlightened manufacturing policies which are far from a coalition of coincidences, has created a specialist yacht-building sector – and a superyacht one with exceptional potential.
Research Design & Methods: This theoretical and empirical study sets out, after defining and describing the superyacht sector by reviewing limited existing research, to apply basic quantitative methods – correlation and regression - to isolate the demand and production factors most likely to explain and ensure continued success. From limited data and previous research it produces a clear result; manufacturing nations with a strong labour market, upholding a highly-skilled, cost-competitive workforce, compared with boatyards in nascent or mature boatbuilding nations, are delivering persistent prosperity with promise of further growth. This, for the first time, weighs the comparative importance of supply-side factors that drive production and points the way for further work to understand its success. Warsaw’s support for manufacturing has quietly created ideal conditions for a niche sector to flourish, success also within reach of countries with a similar labour pool.
Findings: A positive relationship between overall global fleet size and numbers of millionaires in producer countries is confirmed by correlation and then regression analyses prove three hypotheses. First, the dominant influence of competitive labour resources; second, the much lesser (though still important) role of tax policy among other factors, such as industry path dependency and education levels, which can also be expected to be key economic drivers of growth. A third, subsidiary, hypothesis also holds: that a sector with special advantages – in this case luxury products in a resilient marketplace – can outperform other manufacturing segments. The findings confirm the global superyacht market presents significant opportunities for sustained expansion and enterprise for producers like Poland.
Implications/Recommendations: The EU recognises the importance of marine industries to trade and enterprise. However, to take advantage of assured superyacht market growth, policymakers need to continue to nurture a skilled labour pool with funding and training support. They could also cut corporation tax to specifically support boatbuilders, perhaps introducing a lower tier for innovating and expanding industries under Industrial Revolution 0.4 strategies.
Contribution/Value Added: An in-depth examination of a specific sector with appeal to work and wealth creators worldwide, identifying a special labour market premium in Poland and previously unrecognised upside opportunities for all market participants.

Horticulture has emerged as one of the potential agricultural enterprise in accelerating the growth of Indian economy. Cole crops are the most important group of vegetable crops which is widely grown and popular across the world. India holds second position in production of cole crops. The vast production base offers tremendous opportunities for trade in India.The study explores the export performance of major cole crops in India during the period 1990-91 to 2019-20. The present study was computed by CGR, CV, Cuddy Della Valle index, trend analysis and NPC. The major cole crops growth rate of area, production, productivity, export quantity and export value has shown positive and significant growth rate, for period I, period II and overall period except in productivity of cabbage and other brassicas showed positive and non-significant growth rate in period II and export quantity of cauliflower and broccoli showed positive and non-significant growth rate in period I and period II. The coefficient of variation of cabbage and other brassicas for productivity, export quantity, export value was found to be high in period I but area and production was found to be high in the overall period. The co-efficient of variation of cauliflower and broccoli for area production, export quantity, export value was found to be high in overall period, but productivity was found to be high in the period I. The Cuddy-Della instability index of major cole crops was found to be high instability index in production, export quantity and export value during period I area was found to be during overall period except productivity of cabbage and brassicas was found to be high in the overall period. The trend analysis of major cole crops in area, production and export indicates that among the competitive parametric models, in maximum cases cubic models are found best fitted based on R2 and significance of coefficients except in case of cabbage and other brassicas export quantity and export value the compound models was found best fitted and in case of cauliflower and broccoli export quantity the power model was found best fitted based on R2 and significance of co-efficients. The NPC value of cabbage and other brassicas was found lesser than unity (0.52) indicates that possess export competitiveness. The NPC value of cauliflower and broccoli was found greater than unity (1.40) indicates that possess non export competitiveness. Thus, the study concluded that major cole crops have better export potential in future. Hence, it is suggested that to achieve the break through in major cole crops export, there is need to initiate a systematic and long-term export planning at the state as well as national levels.

A well known fact that the exclusively produced surplus crop residue has the potential to yield useful energy and it can be used as the renewable energy source to reduce the conventional energy demand. The present study deals with the feasibility of energy conversion in the production of activated biochar using vacuum pyrolyser from wheat straw and coconut shell. The biomass of 5 kg was fed into the reactor to produce the activated biochar at operational temperature of 500 °C. The Series of steps involved in the production of activated biochar was observed and studied. The individual energy consumption of each utility was evaluated and the energy saving opportunities was pointed out. While energy indices were also computed based on the input and output energy involved in the production. The average amount of the biochar produced during the auditing was found to be 1.525 kg from wheat straw and 1.775 kg from coconut shell. The input and output energy was resulted as 112.796 MJ and 66.597 MJ for wheat straw, 126.051 MJ and 79.975 MJ for coconut shell biochar production, respectively. Based on the results obtained the energy indices were computed and the use of vacuum pyrolyser in the production of activated biochar was found feasible for the efficient energy conversion.

Soil health plays a vital role to ensure sustainable agricultural production. To protect soil health, the Government of India launched Soil Health Cards (SHC) Scheme in 19th February 2015. A sample size of 60 farmers of two groups 30 SHC holders and 30 non-holders were randomly selected for the study. Fertilizer use efficiency was estimated through stochastic frontier analysis for card holders and the results revealed that area and phosphorus were significant variables at 1 and 5 per cent level. For non-holders, human labour and nitrogen was significant at 1 per cent level and machine labour was significant at 5 per cent level. Technical efficiency was also estimated and reported as 20.65 per cent in case of SHC holders and 48.57 per cent for non-holders. Cost of cultivation worked out for card holding farmer (Rs.27171.66/ac) was found to be lesser than the non-holders (Rs.28902.12/ ac). But gross income and net returns for card holders was more when compared to non-holders due to proper utilization of fertilizer and other resources. B: C ratio for card holders was 1.14 and for non-holders it was 1.06. The constraints were ranked using Garrett ranking technique and difficulty in calculating appropriate fertilizer dose matching the nutrient status of soil was ranked as first by card holders and non-issuance of SHC was reported by non-card holders.

The aim of this study is to compare the areas of effectiveness of half-sine monophasic and biphasic depolarizing defibrillation pulses in the diagram of energy / phase of fibrillation cycle. The study was carried out on the ten Tusscher-Panfilov 2006 model of the human ventricular myocyte under the influence of simulated fibrillation in the BeatBox simulation environment under the Fedora operating system. The simulation was carried out on a computer under the Windows 10 operating system, the Fedora operating system was implemented in the Oracle VM VirtualBox virtualization environment. The results of computer simulations have shown that the areas of effectiveness for monophasic and biphasic defibrillation pulses are significantly different. In a biphasic pulse, the fraction of a fibrillation cycle at which refractoriness is extended is significantly higher than that of a monophasic pulse at low defibrillation pulse energies. It can be assumed that this provides the energy advantage of a biphasic defibrillation pulse over a monophasic one.

Resumo: Este artigo analisa como o campo das religiões de matriz africana evoca o discurso racial como narrativa público-política em resposta a atos de intolerância religiosa, destacando o período das eleições municipais de 2020 na região de São Gonçalo (RJ). Como contraface desse processo, examinaremos também como o discurso racial é empregado pelos grupos evangélicos no dia a dia de suas igrejas, articulado com sua ação expansionista e missionária de forma geral e em São Gonçalo. Como suporte teórico para empreendermos a análise das relações entre racialidade, identidade e política, baseamo-nos no conceito de interseccionalidades, categoria que alude à multiplicidade de diferenciações.

Gestos e posturas: dançando com os espíritos
Authors: Cunha João Alipio
Published: March 2022

Resumo: O estudo realizado junto ao grupo Jongo de Pinheiral, na antiga Fazenda Pinheiros, no Vale do Paraíba (RJ), revelou que seus integrantes mantêm uma relação afetiva entre si e têm um histórico de lutas sociais marcado por gestualidades ligadas à dança. Com base nesses dados, apresento, neste artigo, uma análise do ritual praticado por jongueiros e umbandistas dedicado a “passagem para o outro plano” dos espíritos que habitam a fazenda. Para isso, mobilizo os estudos da antropóloga Marlene Cunha no campo dos gestos e postura no candomblé Angola. A análise permite a compreensão dos gestos preliminares, liminares e pós-liminares do ritual.
