Clóvis Moura: sociabilidade e formação intelectual (1940-1950)
Authors: Rocha Gabriel dos Santos
Published: January 2022

Neste artigo analisaremos o percurso de Clóvis Moura (1925-2003) em seus anos de formação intelectual e política, a saber: a juventude em Salvador e Juazeiro da Bahia nos anos 1940. Trata-se de uma etapa, da trajetória do autor, que antecede sua consagração como historiador e sociólogo marxista dedicado às insurreições negras no Brasil escravista e à luta antirracismo e anticapitalismo no pós-abolição. Abordaremos um período no qual a literatura e atividades culturais na esfera do então Partido Comunista do Brasil (PCB) são elementos de grande relevância, ou mesmo centrais, na vida social de Moura, embora a História e a Sociologia já apareçam como temas de seu interesse. As referências intelectuais e políticas presentes na correspondência do autor no referido período nos informam sobre suas escolhas, revelam elementos de seu ambiente social, e nos permitem compreender melhor o processo de sua produção nos anos posteriores.
1968 - 1978: o movimento estudantil como novo personagem?
Authors: Almada Pablo Emanuel Romero
Published: January 2022

O artigo analisa as retomadas das mobilizações do movimento estudantil na década de 1970, com especial atenção a reconstrução institucional da União Nacional dos Estudantes (UNE), seus episódios de mobilização e repressão, como a invasão da PUC-SP em 1977. Questiona-se, a partir da concepção de 'novos personagens' proveniente da obra de Eder Sader, a pertinência do processo de reorganização estudantil, dado a perseguição e o silenciamento de suas ações, no interior dessa matriz teórica. Através da metodologia da sociologia histórica e da análise documental, conclui-se que, na cidade de São Paulo, a relação do movimento estudantil com os setores progressistas da Igreja Católica, em especial na figura de D. Paulo Evaristo Arns, é fundamental para a compreensão de seu avanço organizativo e da construção de mobilizações em prol dos direitos humanos.

Authors: A.W. Yass, , F.G. Habasha, F.G. , S. Al-Sammarai,
Published: January 2022

A systemic study was done on the pathogenesis of experimentally induced Salmonella typhimurium infection in calves. The present investigation was carried out on sixteen normal colostrum fed friesian calves, ranging in age from 3 to 6 weeks. The calves were divided into two equal groups. Group I inoculated orally with (1.5 x 10'') Salmonella typhimurium and group IA served as control. 

• The early ultrastructural alteration in the mesenteric lymph nodes was the presence of many free Salmonella in localized vacuoles. The interaction between the host cells and phagocytized Salmonella was also observed.
The "rediscovery" of the meaning of life in the time of the pandemic
Authors: Pesci Furio
Published: January 2022

The time of the pandemic is characterized by multiple painful experiences: illness, death, the limitation of personal freedoms, the fear of contagion, widespread impoverishment. It is difficult to talk about the "positive" aspects of an emergency that is not over yet, but during its course it is possible to grasp from those same experiences that characterize it a new opportunity to reflect on aspects of human existence that the consumerist mentality previously placed in the background. The restrictions imposed by the health emergency have led to a collapse in investments and consumption which, if it has complicated the economic situation of many countries, makes it possible to "discover" the possibility that life can pass peacefully even without all the comforts and possibilities previously available. With this new awareness it is possible to reflect on the "philosophical" question of the meaning of life and on what is really "essential" for a possible happiness despite the contingencies of the time we live in.
Beauty and the wonder of poetry. Voices of a poetic education to revive our times
Authors: Ulivieri Stiozzi Stefania
Published: January 2022

Poetry is an epiphany of the gaze, an arousing vision. It opens a passage unexpectedly, where a glimmer of truth is found. The poetic word is a metaphor for this extraordinary time, revealing not only a fear of the other and the threat of death – which has become a tangible presence – but also the beauty of fragility when it is cultivated as a gesture of care for oneself and for the world. A word capable of restoring a look of wonder accords the verses of some poets, bearing witness to a different way of thinking. The text seeks to explore their voices, linked by a word that cultivates the expansion of detail and the beauty hidden between the folds of a troubling time. In a moment of estranging separation, their inspiration promotes an education consisting of listening and receptivity, reviving silence, inviting gestures of devotion and intimacy towards oneself and to others and cultivating an imperishable art of life.
La riscoperta dell'amicizia nell'età adulta in tempo di pandemia
Authors: Zannoni Federico
Published: January 2022

In recent decades we have witnessed the disruptive rise of an ultraliberalism which, by enhancing the autonomy of the individual, has given the collective dimension a primarily instrumental connotation; the affirmation of the “self-centered man” (Bertin’s definition), that pursues the experience of the world above all on the level of “possession”, has intertwined with the crisis, especially among adults, in the practice of friendship, understood as a relationship of voluntary, free interdependence, which continues over time through manifestations of sharing, complicity, intimacy, affection and mutual assistance. The social isolation resulting from the pandemic event has led to the reconsideration of the importance of friendships and to the search for new opportunities for meeting, online or face to face (possibly respecting the current restrictive rules for the containment of the epidemic), in which “being together” is predominant over “doing something together”.

Published: January 2022

Reading the needs of students, in the modern-day reality, requires teacher to intervene with innovative teaching methodologies, able to integrate the two dimensions (analog and digital) of teaching and to promote talents. With these aims the comprehensive institute “Foscolo-Gabelli” in Foggia, formerly DADA school, signatory of a memorandum of understanding with the University of Foggia has included the DADA Teams in the Three-Year Plan of the Training Offer. They are cooperative working groups, carried out in curricular time. Within the DADA Teams, students are supported in learning by multimedia tools and learn to learn through transversal educational paths, discovering their talents passions and attitudes. This study aims to document the experimentation contextualizing it in the panorama of research on the interactions between teaching and talent development, where the use of flexible and “open” technologies and learning environments can be a driving force for change.
The aesthetic experience of learning between real and virtual
Authors: Di Biasio Simone
Published: January 2022

From Socrates to Dewey, learning is linked to reality and movement, in relation to the aesthetic implications of the communication/education dynamic: the possibilities offered by the virtual in the educational logic exist as a choice to increase reality, not decrease it. The article retraces stages of pedagogical thought in which the question of movement is central, opening the history of education to the work of Marshall McLuhan who first investigated the relationship media-learning. Also in the didactic practices of the current pandemic moment of "distance learning” has been introduced, we cannot disregard the idea of education as an "aesthetic experience", in search of beauty and of a balance, precarious yet rich, between real and virtual.
Relation of Urobilinogen Presence Resence in the Selection of Food (Salty or Sweet)?
Authors: Qadir Muhammad Imran , Hameed Fatima
Published: January 2022

The total amount of 100 subjects were contributed in this review and all were the students who are studying in Bahauddin Zakariya University Multan, Pakistan. The bilirubin is metabolized in the gut which produced a colorless pigment known as urobilinogen. It is by-product of bilirubin which is used to break down the red blood cells in hemolysis. Salty food contains usually more minerals and vitamins while sweet food is enriched with carbohydrates, water and many other fats soluble substances. Every person has a unique taste according to their taste buds. A questionnaire based was made to relate the urobilinogen with the food (salty or sweet). Urinalysis is a method which is used to measure the urobilinogen in urine. It was concluded that there is a scientific relation between the presence of urobilinogen in urine with eating of salty or sugary food. Table no. 1 represents that urobilinogen play important role in the choice of eating either salty food more or sweet.

Published: January 2022

Severe acute respiratory syndrome coronavirus- 2 (SARS-CoV-2) has affected millions of people across the world engendering an unprecedented pandemic. Coronavirus disease (COVID)-19 can present asymptomatic or in the form of the acute respiratory syndrome, viral pneumonia,or sepsis. Due to the novelty of the disease, the endocrine manifestations are not fully understood. It becomes indispensable to address the underlying endocrine disruptions contributing to the severe form of illness and thereby increasing the mortality.We discuss here the SARS-CoV-2 virus and endocrine reverberations based on the research with structurally similar SARS-COV-1. SARS-CoV-2 enters the body via its attachment to the angiotensin-converting enzyme 2 (ACE2) receptors. Apart from lungs,ACE2 expression on various organs can lead to endocrine perturbations.In COVID-19 infection, pre-existing endocrine disorders warrant cautious management and may require replacement therapy. COVID-19 and its repercussions on hormones are discussed extensively in this review.

Published: January 2022

The occurrence of adrenal crisis after retroperitoneal laparoscopic unilateral adrenalectomy is usually concealed. If not timely diagnosis and treatment,it may cause shock, and even lead to death. It is very difficult to distinguish the clinical manifestations of adrenal crisis from nausea, vomiting, fatigue,gas separation from the lower diaphragm, abdominal pain, hypotension, hypertension, fever and hypothermia after operation. This makes it very difficult to identify and diagnose adrenal crisis early. This article mainly discusses the early recognition, diagnosis and treatment of adrenal crisis after unilateral adrenalectomy by retroperitoneoscope.
Covid-19 Mutations and the Effect of Different Vaccines on Immune Memory
Authors: Sofra Xanya
Published: January 2022

We traced the coronavirus classification and evolution, analyzed the Covid-19 composition and its distinguishing characteristics when compared to SARS-CoV and MERS-CoV. Despite their close kinship, SARS-CoV and Covid-19 display significant structural differences,including 380 amino acid substitutions, and variable homology between certain open reading frames that are bound to diversify the pathogenesis and virulence of the two viral compounds. A single amino acid substitution such as replacing Aspartate (D) with Glycine (G) composes the D614G mutation that is around 20% more infectious than its predecessor 614D. The B117 variant, that exhibits a 70% transmissibility rate, harbours 23 mutants,each reflecting one amino acid exchange. We examined several globally spreading mutations, 501.V2, B1351, P1, and others, with respect to the specific amino acid conversions involved. Unlike previous versions of coronavirus, where random mutations eventually precipitate extinction, the multiplicity of over 300,000 mutations appears to have rendered Covid-19 more contagious, facilitating its ability to evade detection, thus challenging the effectiveness of a large variety of emerging vaccines. Vaccination enhances immune memory and intelligence to combat or obstruct viral entry by generating antibodies that will prohibit the cellular binding and fusion with the Spike protein, restricting the virus from releasing its contents into the cell. Developing antibodies during the innate response,appears to be the most compelling solution in light of the hypothesis that Covid-19 inhibits the production of Interferon type I, compromising adaptive efficiency to recognize the virus, possibly provoking a cytokine storm that injures vital organs. With respect to that perspective, the potential safety and effectiveness of different vaccines are evaluated and compared,including the Spike protein mRNA version, the Adenovirus DNA, Spike protein subunits, the deactivated virus genres, or, finally, the live attenuated coronavirus that appears to demonstrate the greatest effectiveness, yet,encompass a relatively higher risk.

Introduction: Oral cancer is one of the most common cancers globally and in Sri Lanka, which follows premalignant lesions. It is curable if it is detected early. Several adjunctive methods to diagnose premalignant lesions early are available. Among these, Toluidine blue staining method before a biopsy is currently receiving much attention.

Method: This is a prospective study done by studying 103 patients presented to the Oral and Maxillofacial Surgery Unit, District General Hospital, Gampaha, Sri Lanka. The oral lesions of all the patients are categorized as benign, premalignant, and malignant by clinical examination. Toluidine Blue mouth wash is introduced to all the patients, followed by biopsy from the stained sites and the clinically decided sites in non-stained lesions. Histopathological diagnosis was obtained for all cases. The accuracy of diagnosis of premalignant, malignant, and benign cases by clinical assessment and by using Toluidine blue was assessed and compared statistically in relation to sensitivity, specificity, positive predictive and negative predictive values, and likelihood ratios (LR).

Results: Toluidine blue has no added advantage over clinical examination in our setup even though it might be helpful in screening. However, it has an added value to confirm clinically benign cases as benign.

Conclusion: Toluidine Blue can be used as an adjunct in screening and to confirm clinically benign cases so that those can be followed up in clinics without doing unnecessary biopsies.

Published: January 2022

This study focuses on the markers of tectonically stressed zones inside the rock mass, that were identified during the regional geodynamic zoning of the mine fields of the Talnakh orogenic system. Identification features for tracing geodynamically active structures within the western flank of the Talnakh orogenic system have been identified based on morphometric analysis of the Tunguska series sediments, which are the upper layer of the ore-bearing intrusions and associated ore deposits. In the larger morphostructural groups, the boundaries of contrastingly alternating zones of elevated and depressed absolute depths at the base and the roof of the Tunguska series sediments represent the boundaries of tectonic blocks of different elevation levels with sharply contrasting indices of terrain stress. The circular-shaped structures highlighted in the morphostructural schemes spatially coincide with the tectonic forms were formed as the result of strike-slip and torsional processes. A heterogeneity, which is reflected in the allocation of blocks with different values of the stress distribution coefficient (K) is identified in the initial stress field of the Tunguska series sediments. The boundaries of the geodynamic blocks that were identified using to different methods are identical. It is established that the assumed faults correspond to the faults identified based on the detailed exploration data.
Methodological approach to characterizing pollution of natural water bodies using satellite data with account of aggregation of finely dispersed mineral processing waste
Authors: Ostapenko S.P. , Mesyats S.P.
Published: January 2022

The level of the environmental impact of the mining industry specifies the urgency of ecological management of the natural resources based on the satellite monitoring data. The high content of the suspended mineral particles in the industrial waters and the requirement to reduce their access to the natural water reservoirs determine the need to characterize the mininginduced pollution that can be carried out correctly with due account of the aggregate stability of dispersions. In spite of the theoretical concepts, prediction of the particles aggregation is limited by a lack of data on their interaction parameters. In order to parametrize the interactions in the mineral-water-mineral system it is proposed to use experimental data on aggregation of finely dispersed particles, obtained by the laser diffraction method in the equilibrium conditions. For this purpose the procedure of the experimental appraisal of the effective Hamaker constants has been elaborated using ores of developed deposits of the Kola mining complex as an example. The authors have studied the conditions of the surface layer of natural water reservoirs in the most industrially developed central part of the Murmansk region and defined characteristics of pollution with finely dispersed by-products of the mineral raw material treatment, according to the satellite observation data of the spatial distribution of the normalized difference turbidity index. The authors have established that the least propagation of the pollution into the natural water reservoirs is observed in the case of the apatite-nepheline ores processing by-products, which is explained by the effective aggregation of the finely dispersed nepheline particles. The proposed approach to apply data on mineral particles aggregation for interpretation of the satellite observations does not require carrying out in-situ observations and makes it possible to identify the mining-induced pollution of natural water reservoirs in industrial territories using suspended particles.

The typology of rubies and their industrial significance
Authors: Barnov N.G. , Shchiptsov V.V.
Published: January 2022

Information on the International Genetic Classification of Noble Corundum is given. The scheme of location of the main deposits and occurrences of ruby-bearing complexes of the world is attached: 1 – magmatic; 2 – metamorphogenic; 3 – sedimentary (residual ancient crusts of chemical weathering, alluvial and dealluvial-alluvial placers). The location of ruby objects is shown, including the largest areas of depleted, currently operating and promising for the near future ruby deposits in 36 countries around the world. The main typological features of rubies are described. It is emphasized that all properties of rubies are determined by their primary indigenous origin. The typology of rubies is based on the principles of the relationship between magmatism and metamorphism in the formation of the groups under consideration. Hydroblasting and selective crushing methods for mining of corundum-bearing complexes are characterised. The trend towards increased research into the commercial exploitation of the primary sources of ruby-bearing complexes is highlighted. In countries with highly developed mining industries, underground mining is the main way to extract gemstones.
On determining the parameters of face blocks during mining operations with backhoes
Authors: Litvin O.I. , Litvin Ya.O. , Tyulenev M.A. , Markov S.O.
Published: January 2022

The backhoe hydraulic shovels (backhoes) have been widely used in open-pit mining operations in the Kuznetsk coal basin since the early 2000s. Now their number is growing every year, both because new operations begin on new sites, and because of the backhoe advantages. However, up to now parameters of their operation, more particularly the parameters of the face blocks, are often taken according to the actual data, i.e. based on the accumulated experience of the mining companies, and are not calculated using the approved scientifically validated methods. In the given article the authors give some preconditions for creation of a uniform methodology to calculate parameters of the face blocks depending on mining-geological and miningtechnical conditions. It is noted that the manufacturers of excavation equipment quote the data corresponding to the maximum possible parameters of the equipment operation, in particular the height of the excavated layer, as a result of which it is rather difficult to apply this in practice. Preliminary conclusions about the need to take into account the diversity of the above conditions and their interrelation with the parameters of a particular model of the excavation and loading equipment have been made.
Experience of CAE Fidesys application in numerical geomechanical modelling of Zhdanovskoe deposit
Authors: Miroshnikova L.K. , Mezentsev A.Yu. , Kadyralieva G.A. , Perepelkin M.A.
Published: January 2022

The Zhdanovskoe copper-nickel sulfide ores deposit is located in the north-west of the Murmansk region and is a mineral raw material source for JSC «Kola MMC». The main mining method used is sublevel caving. In some areas, due to the complex shape of the ore bodies, the open stoping mining method is used which requires determining stable parameters of stopes and pillars. It is necessary to study the stress-strain state of the deposit to ensure safe mining conditions. One of the possible solutions is the modeling of the stress-strain state of rock mass using the finite element method, for example, CAE Fidesys, which is FEMbased software. The use of CAE Fidesys for solving geomechanics tasks allows creating models of individual excavation units to determine the stability of stopes and pillars, and large-scale models that include several ore bodies and areas of the host rock mass. The article considers solutions of both types of geomechanic tasks using CAE Fidesys for conditions of the Zhdanovskoe deposit.
Assessment of various scenarios for the development of mineral deposits in the region (as exemplified by the Republic of Tuva)
Authors: Dabiev D.F. , Chupikova S.A. , Chuldum A.F.
Published: January 2022

It is shown that Tuva has a sufficiently rich mineral and raw material diversity and the potential for their development. Nevertheless, the development of the republic is hindered by the existence of transport and infrastructure restrictions, to eliminate which, first of all, it is necessary to build a railway along the Kyzyl-Kuragino highway. On the other hand, given the border area of the territory that adjoins western Mongolia, there is a possibility of implementing various scenarios for the construction of railway tracks. The calculations performed to evaluate scenarios for the development of mineral resources of the republic using methods of intersectoral assessment shows that when implementing a pessimistic option for the development of the potential of mineral resources of Tuva (in which the construction of the railway to Tuva is frozen and only deposits of non-ferrous metals and gold are developed), the gross regional product of the republic will grow to 164 billion rubles, which will be 45% of the growth of this indicator in relation to the GRP of 2018. With the implementation of the optimistic option I, (in which it is planned to build a railway along the Kuragino-Kyzyl highway, coal deposits, non-ferrous metals, gold are being developed), the GRP of the republic will grow up to 351 billion rubles. In addition, calculations have been made for the construction of railways that would connect Tuva with Mongolia and China.

Penyaringan tes ujian pada penerimaan mahasiswa baru atau biasa disingkat dengan PMB, merupakan salah satu tahapan selain melengkapi berkas administratif. Pada Universitas Islam Lamongan (Unisla), tes penyaringan ini digunakan untuk melihat potensi calon mahasiswa berdasarkan nilai yang diperoleh. Dilihat dari hasil tes ini, maka langkah selanjutnya adalah panitia PMB dapat menentukan calon mahasiswa yang harus mengikuti kuliah matrikulasi atau tidak. Untuk saat ini penentuan dari hasil nilai tes dilakukan secara mengurutkan dari nilai tertinggi. Panitia juga akan memberikan nilai batas minimal dari nilai rata-rata tes yang diberikan untuk menentukan calon mahasiswa yang berhak tidak mengikuti kuliah matrikulasi. Pada penelitian ini akan membuat pengujian model klaster untuk menentukan kelompok calon mahasiswa yang tidak wajib mengikuti kuliah matrikulasi dan yang wajib mengikuti. Metode klaster yang digunakan adalah Fuzzy C-Means. Dengan menggunakan data uji sebanyak 400 data calon mahasiswa dan menggunakan 5 atribut nilai dari hasil tes PMB. Dan pengujian metode ini diimplementasikan pada Software Matlab telah mendapatkan hasil klaster 1 (Tidak Mengikuti kuliah matrikulasi) sebanyak 178 dengan nilai tes rata-rata 273,039 sedangkan pada klaster 2 (Wajib mengikuti kuliah matrikulasi) sebanyak 222 dengan nilai tes rata-rata 212,610.
