Esta tese parte da questão em se propor a restauração da paisagem para mais resilientes e adaptativas (LANDIS, 2017; FOLEY et. al., 2005), que estimule a produção de diferentes serviços ecossistêmicos, seus bens e serviços em diferentes escalas, em consequente mitigação aos episódios do clima extremo, como inundações e secas, e demais mudanças ambientais, como a perda da biodiversidade (ROCKSTROM et al., 2009; STEFFEN et al., 2011). Tem como problemática de partida a crise hídrica de 2013-2015 no estado de São Paulo, que justificou como medida de adaptação a transposição de parte da vazão das águas da bacia do rio Paraíba do Sul para o sistema Cantareira, sobrecarregando o uso deste curso d´água, que já abastece algumas cidades do sudeste de Minas Gerais, as cidades do Vale do Paraíba paulista e grande parte da região metropolitana fluminense (MENDES FILHO et al., 2016).

Published: April 2021

Essa pesquisa busca entender os espaços públicos esportivos e a sua apropriação pela comunidade, através de políticas públicas e engajamento dos indivíduos, analisando a estruturação da cidade a partir das suas áreas periféricas, e a relação entre o cidadão e seus espaços públicos, considerando as práticas sócio espaciais cotidianas que neles se estabelecem enquanto representação dos diferentes usos da cidade. Pretende-se averiguar, se a população utiliza os equipamentos esportivos dispostos na periferia, entendidos, nesse estudo, como instrumento de inclusão social, esporte e lazer para população, que expressa redefinição constante dos espaços públicos enquanto expressão do processo de produção da cidade, das suas contradições, conflitos e reflexos. As periferias das cidades se tornam espaços recortados para a pesquisa por se entender que são esses espaços relegados ao esquecimento pelo poder público e negado o direito de exercício da cidadania. No entanto, a possibilidade de um espaço público esportivo, onde o indivíduo tem algumas das suas necessidades atendidas, por meio de vivências lúdicas e sociais, adiciona a essa comunidade esperança de se sentir integrado dentro da sociedade. Para isso é importante a produção de espaço público que beneficie todo o munícipio. Por meio de análise dos questionários e da literatura revisada, além da descrição e discussão dos mapas, gráfico e da conclusão da tese iremos buscar o resultado da tese.

Este projeto de Iniciação Científica tem como finalidade auxiliar no desenvolvimento da adaptação de metodologia para a construção de uma versão brasileira do modelo que calcula a Pegada Ecológica de Nitrogênio (N-Footprint), desenvolvido por Leach et al. (2012). O modelo realiza os cálculos a partir de um Fator de Nitrogênio Virtual que utiliza variáveis relacionadas ao consumo geral de alimentos e energia pela população. O trabalho desenvolvido neste plano colabora com o desenvolvimento do projeto internacional INMS (International Nitrogen Management System) gerido pela UNEP (programa ambiental das Organizações das Nações Unidas) que tem como finalidade melhorar o controle global do nitrogênio unindo a comunidade científica e a sociedade civil. Como muitos dos efeitos relativos ao uso do nitrogênio estão intrinsecamente relacionados à demanda de consumo de produtos agropecuários, é importante buscar informações além de dados restritos ao ciclo biológico e físico, incluindo também informações socioeconômicas, inclusive comportamentais.Neste sentido, esta proposta teve como objetivo criar indicadores para nitrogênio, a partir dos dados levantados sobre a alimentação da população da bacia do Rio da Prata, considerando a relação das atividades antrópicas, como as alterações do meio, com o nitrogênio reativo.

A Survey of Computational Intelligence in Educational Timetabling
Authors:   School of Engineering and Technology, CQUniversity, Rockhampton, Q4702 Australia, Zhu Kaixiang , Li Lily D , Li Michael
Published: April 2021

Timetabling problems have been widely studied, of which Educational Timetabling Problem (ETP) is the biggest section. Generally, ETP can be divided into three modules, namely, course timetabling, school timetabling, and examination timetabling. For solving ETP, many techniques have been developed including conventional algorithms and computational intelligence approaches. Several surveys have been conducted focusing on those methods. Some surveys target on particular categories; some tend to cover all types of approaches. However, there are lack of reviews specifically focusing on computational intelligence in ETP. Therefore, this paper aims at providing a reference of selecting a method for the applications of ETP by reviewing popular computational intelligent algorithms, such as meta-heuristics, hyper-heuristics, hybrid methods, fuzzy logic, and multi-agent systems. The application would be categorised and described into the three types of ETP respectively.

Published: April 2021

In Southeast Asia, durian is affectionately called the king of fruit. Durian is the most popular crop planted in eastern and southern of Thailand. The total crop is around 600,000 tons per year; among this, 500,000 tons of the total production were exported worldwide. In Thailand, the knowledge of durian production is based on experience from generation to generation, especially the knowledge of durian pests and diseases control. This paper presents the ontology knowledge based for durian pests and diseases retrieval system. The major contributions of the system consist of 1) the stored knowledge of durian pests and diseases and 2) the diagnosis of durian diseases and the suggestions for the treatments. The ontology knowledge consists of 8 main classes: 1) diseases, 2) pests, 3) cultivars, 4) symptoms of bunch, 5) leaf area symptoms, 6) symptoms of the branches and trunk, 7) symptoms of fruit, and 8) symptoms of root and growth. The experimental results yielded 100% of precision, 88.33% of recall, and 93.8% of overall performance.

Published: April 2021

The global luxury market reached €1.17 trillion in sales in 2018 and the global market for personal luxury goods is forecast to grow to €290 billion by 2020. Close to 70% of the global personal luxury goods sales are tribute by Generations X and Y. When considering the fact that Generation X is the smaller consumer segment based on a population size, compared to baby boomers or generation Y, Gen X segment’s total expenditure on personal luxury goods, which was greater than that of either of generational cohorts is highly noteworthy. A recent study by Kim (2019) found that both generations X and Y are much heavily involved in luxury goods consumption through the ownership of multiple product categories including clothing, shoes, handbags and small leather goods, and jewelry, compared to older and younger baby boomers. Regarding personal luxury consumption at different price points such as absolute luxury vs. accessible luxury has not received much attention. Thus, this study aims to provide insights by investigating US affluent Generations X and Y consumers’ perception and lifestyle variables and their predictability of behavioral variables in the personal luxury marketplace. Using a nationwide representative sampling and online survey, a final sample of 299 responses were collected and used for this study. The confirmatory factor analysis of the measurement more as well as proposed conceptual model revealed that data fit the proposed conceptual model well. All, except one, research hypotheses received statistical support. A structural equation modeling using multiple group analysis revealed that absolute luxury owners are significantly different from accessible luxury owners. Based on the findings, pragmatic implications and future research directions are provided.

Credit risk is the possibility of a loss resulting from a borrower’s failure to repay a loan or meet contractual obligations. With the growing number of customers and expansion of businesses, it’s not possible or at least feasible for banks to assess each customer individually in order to minimize this risk. Machine learning can leverage available user data to model a behavior and automatically estimate a credit score for each customer. In this research, we propose a novel approach based on state machines to model this problem into a classical supervised machine learning task. The proposed state machine is used to convert historical user data to a credit score which generates a data-set for training supervised models. We have explored several classification models in our experiments and illustrated the effectiveness of our modeling approach.

Achieving and sustaining competitive advantage is a goal among firms, but it is increasingly challenging in a rapid changing and sophisticated environment. Most of the environmental management undertaken by firms in developing countries are not able to increase the competitive advantage of the product. Hence, this study investigates proactive capabilities that need to be developed in a dynamic environment where it involves green product innovation, environmental proactivity, alliance pro-activeness, and knowledge-based dynamic capabilities that impact on competitive advantage performance. This study involved a survey of 157 manufacturing firms with ISO 14001 certification throughout Malaysia. By implementing structural equation modelling approach, the results provided evidence of positive and significant direct effects of green product innovation and environmental pro-activity on firm’s competitive advantage. The relationship of alliance pro-activeness was fully mediated by the presence of knowledge-based dynamic capabilities as a condition to survive and prosper in a competitive market.
Stridor at birth: a diagnostic dilemma
Authors: Ragu Rajparath , U. Ramkumaar
Published: April 2021

Stridor is a common complaint in neonates. Double aortic arch (DAA) is a congenital anomaly of the aortic arch. It is the most common type of complete vascular ring. When it occurs, the connected segment of the aortic arch and its branches encircle the trachea and esophagus, leading to symptoms related to these two structures. Association with respiratory distress mandates early flexible bronchoscopic examination of the airway. We report here the diagnosis and management of a neonate with double aortic arch that presented as stridor at birth. Persistence of stridor after surgery and its management was highlighted.

Published: April 2021

Background: Triage in an emergency is sorting out the patients based on the severity of illness and prioritizing care accordingly. Kumar et al devised a score taking temperature, heart rate, respiratory rate, blood pressure, capillary refill time, oxygen saturation, and sensorium. We propose to evaluate a sickness scoring system based on capillary refill time, sensorium using AVPU score, blood pressure, and oxygen saturation by pulse oximetry (CABS) which are least affected by stress, anxiety, temperature, acidosis, etc.Methods: Prospective study in children admitted consecutively in the age group one month to 12 years from 1st January 2019 to 31st December 2019, to paediatric intensive care unit. Triage score applied at the time of the first contact. Each variable in the study was scored as 0 for being normal and a score of 1 for being abnormal. The total score for each child is obtained. The outcome at discharge was correlated with the study variables and total score. ROC curve analysis was done for the overall predictive ability of the score.Results: Of 346 children admitted, 27 expired, and 319 children were discharged. The risk of mortality increased with the increasing score. CFT, sensorium, blood pressure, and oxygen saturation are all significantly associated with mortality. A cut-off score of 2 has the highest sensitivity and specificity of 96.3% and 70.2%. The total score has 90% predictive accuracy as AUC is 0.913.Conclusions: As no special training is required for its implementation, the score is promising as a triage tool in resource-poor settings.

Brecha de género en el acceso al financiamiento en Centroamérica y República Dominicana
Authors: Auguste Sebastián , Prat Jordi , Braun Gisele
Published: April 2021

La evidencia empírica internacional muestra que las mujeres tienen menos acceso al financiamiento, tanto al crédito personal como al crédito empresario (según el género de quién lidera la empresa). Esta brecha de género, que se debe a factores de oferta y de demanda, preocupa, tanto desde el punto de vista de equidad o igualdad de oportunidades, como de la eficiencia, ya que en una economía de mercado el acceso al financiamiento es clave para la asignación eficiente de los recursos, y cualquier imperfección en su funcionamiento se puede traducir en menos crecimiento económico. En este trabajo se analiza la brecha de género con tres bases de datos distintas, Global Findex, una encuesta a nivel de individuos, SME Finance Forum, datos agregados estimados, y Enterprise Survey, una encuesta a nivel empresarial que informa el género del gerente general. Se destaca que, en ningún caso, ni a nivel personal ni a nivel empresarial, ha sido posible eliminar las brechas incluyendo factores observables. Por lo tanto, las mujeres en la región están más desaventajadas y esto es un motivo de preocupación, ya que incide en la productividad de la economía, la fertilidad y la tasa de acumulación del capital humano, tres dimensiones donde los países estudiados muestran déficit.

The empirical evidence on their success, however, is still inconclusive. This study designs and evaluates two training programs focusing on soft skills, which are adapted to the Jamaican context. The first program provides soft-skills training on personal initiative, including the development of a proactive mindset and perseverance after setbacks. The second program combines soft-skills training on personal initiative with traditional training on hard skills aimed at changing business practices. Both programs are evaluated using a randomized controlled trial design involving 945 entrepreneurs in Jamaica. Findings indicate positive effects of the intensive soft-skills training, but not of the training combining soft and hard skills, on business outcomes (i.e., sales and profits) in the short-term (i.e., three months after the implementation of the trainings). The positive short-term effects of the soft-skills training are concentrated among men and are not significant for women. These effects, however, vanish when measured 12 months after the trainings. Nonetheless, the soft-skills training show persistent positive effects on some targeted soft skills, which are measured with both self-reported and incentivized measures.

VAJİNİSMUSUN ÜSTESİNDEN GELMEK: TÜRKİYE’DE BİR BAŞARI HİKAYESİ OLARAK CİNSEL BİRLEŞME
Authors: ŞEN Neslihan
Published: April 2021

Bu makale, kadınlarda cinsel ilişkiye girememe sorunu olarak tanımlanan, cinsel işlev bozukluğu vajinismusu analiz etmektedir. Mevcut araştırmalar, Türkiye’yi vajinismusun dünyada en çok kayıt altına alındığı ülke olarak işaret etmektedir. Vajinismus kültüre bağlı hastalıklar arasında gösterilmese bile görülme sıklığı ülkeden ülkeye değişir. Türkiye’de sık rastlanan bir cinsel işlev bozukluğu olduğundan vajinismus ülkemizde beden ve cinsellik algısına, toplumsal cinsiyete, kadınlığa, erkekliğe, heteroseksüelliğe, aile ve evlilik kurumuna dair önemli ipuçları verir. Bu makalede İstanbul’da katıldığım vajinismus grup terapilerini kaynak olarak kullanıp bedenen iyileşmenin nasıl tamamen cinsel birleşmeyi (penetrasyon) başarabilmekle özdeşleştirildiğini irdeleyeceğim. Türkiye’de 2000’lerde yaşanan sağlık alanındaki dönüşümle artan özel klinikler hastalığın bir rant haline gelmesine ve tedavi sürecinin yine kadın bedeni üzerine odaklanmasına neden olmaktadır. Bu makale cinsel birleşmenin kadın bedeni üzerinden medikalizasyonu ve metalaşmasına dikkat çekmektedir. Ayrıca, bu süreçte kadının kendisiyle, aynı tanıyı almış diğer kadınlarla ve tedavi sürecinde karşılaştıkları uzmanlarla ilişkilerinin bu çerçevede yeniden nasıl düzenlendiğini incelemektedir.
HİMENOPLASTİDEN SONRA: HİMENOPLASTİ SONRASI İYİLEŞME SÜRECİNDE DEVİNİMSİZLİK ALANI VE NEOLİBERAL (NA)BAKİRE KADININ İNŞASI
Authors: GÜZEL Hande
Published: April 2021

“Kızlık zarı dikimi” olarak tabir edilen himenoplasti ameliyatları, kadınların daha önceden vajinal penetrasyon içeren cinsel ilişki yaşamış olmalarına rağmen, ameliyattan sonraki ilk ilişkilerinde bakire olduklarını iddia etmek amacıyla kanama sağlamalarını amaçlamaktadır. Bu ameliyatlar, tıp çevrelerinde etik olarak tartışmalı kabul edilmekte ve hatta bazı hekimler tarafından bir ‘suç’ olarak görülmektedir. Buna rağmen çok sayıda jinekolog ve plastik cerrah bu ameliyatları gerçekleştirmektedir. Bu makale, çevrimiçi forum gönderileri (2010-2017) ile İstanbul, Ankara ve İzmir’de gerçekleştirilen yarı yapılandırılmış derinlemesine görüşmeler (2016-2017) üzerinden ‘kalıcı’ himenoplasti sonrası iyileşme dönemine odaklanmaktadır. Kadınlar, ameliyat sonrasında, doktorların ameliyat öncesinde kanamanın gerçekleşeceğine dair kendilerine verdikleri garantinin geçerli olmadığını fark etmektedirler. Bu makalede, Joanna Latimer’in “tecil alanı” (2007a) ve “devinim alanı” (2007b) kavramlarından yola çıkılarak doktor-hasta ilişkisindeki güvenin zedelenmesiyle birlikte kadınların iyileşme döneminde bir devinimsizlik alanına sıkıştığı öne sürülmektedir. Bu devinimsizlik alanından çıkmak amacıyla kadınlar, çevrimiçi forumların da yardımıyla, kendilerini iyileştirme sorumluluğunu üstlenirler. Böylece neoliberal bir (na)bakire kadının inşası mümkün olur.
Prediction of Difficult Tracheal Intubation by Artificial Intelligence: A Prospective Observational Study
Authors: ÇELİK Fatma , AYDEMİR Emrah
Published: April 2021

Aim: Many predictive clinical tests are used together for preoperative detection of patients with difficult airway risk. In this study, we aimed to predict difficult intubation with different artificial intelligence algorithms using various clinical tests and anthropometric measurements, besides, to evaluate the accuracy performance of Cormack and Lehane (C-L) classification with artificial intelligence.
Material and Methods: This study was conducted as a single-blind prospective observational study between 2016 and 2019. A total of 1486 patients with American Society of Anesthesiologists physical status I-III, scheduled to undergo elective surgery and requiring endotracheal intubation, were included. Demographic variables, clinical tests and anthropometric measurements of the patients were recorded. Difficult intubation was evaluated using the 4-grade C-L system according to the easy and difficult intubation criteria. Difficult intubation was tried to predict using 16 different artificial intelligence algorithms.
Results: The highest success rate among artificial intelligence algorithms was obtained by the RandomForest method. With this method, difficult intubation was predicted with 92.85% sensitivity, 96.94% specificity, 93.69% positive predictive value and 96.52% negative predictive value. C-L classification accuracy performance also determined as 95.60%.
Conclusion: Artificial intelligence has been considerably successful in predicting difficult intubation. Besides, C-L classifications of easy and difficult intubated patients were successfully predicted with artificial intelligence algorithms. Using a 6-grade modified C-L classification for laryngeal view may provide stronger difficult intubation prediction. A safer and more potent prediction in training artificial intelligence can be achieved by adding individual differences and clinical features that support the definition of difficult intubation.

Authors: ECEVIT Ata , KARACA Okay Güven , KALENDER Mehmet , DARÇIN Osman Tansel
Published: April 2021

Aim: Tunneled hemodialysis catheters are frequently used for hemodialysis patients and provide temporary venous access. However, it causes complications such as catheter-related infection, pneumothorax and hematoma. In this study, we aimed to evaluate the infections, complications and catheter patency rates that developed after the use of tunnel catheters connected to three different access routes.
Material and Methods: A total of 145 patients who underwent hemodialysis due to chronic renal failure and who were placed on permanent hemodialysis catheter were included. In this study, jugular vein route was used as the first choice for the dialysis access route, when other access routes were needed due to complications and infection, femoral vein route was the second choice, while subclavian vein route was the third choice.
Results: The femoral vein group had the highest infection rate and the lowest patency rate (both p<0.001). The infection rate at the end of one year was 65.3%, 95.6%, and 64.0% for the jugular vein, femoral vein and subclavian vein, respectively. At the end of one year, patency rates for the jugular vein, subclavian vein and femoral vein were 57.3%, 6.7%, and 32.0%, respectively.
Conclusion: Although the jugular vein is the first choice for venous entry in hemodialysis patients, femoral and subclavian veins are also used. In this study, the jugular vein was the best option in terms of patency rate and infection. The femoral vein, on the other hand, had the worst patency rate and was also the access route with the highest infection rate.
Methods for Monitoring the Psychophysiological State of a Human Operator via Emotions Reflected in Facial Expressions and Analysis of Blinking Characteristics using Deep Convolutional Neural Networks
Authors: Korsun O.N. , Yurko V.N.
Published: April 2021

We analysed two approaches to estimating the state of a human operator according to video imaging of the face. These approaches, both using deep convolutional neural networks, are as follows: 1) automated emotion recognition; 2) analysis of blinking characteristics. The study involved assessing changes in the functional state of a human operator performing a manual landing in a flight simulator. During this process, flight parameters were recorded, and the operator’s face was filmed. Then we used our custom software to perform automated recognition of emotions (blinking), synchronising the emotions (blinking) recognised to the flight parameters recorded. As a result, we detected persistent patterns linking the operator fatigue level to the number of emotions recognised by the neural network. The type of emotion depends on unique psychological characteristics of the operator. Our experiments allow for easily tracing these links when analysing the emotions of "Sadness", "Fear" and "Anger". The study revealed a correlation between blinking properties and piloting accuracy. A higher piloting accuracy meant more blinks recorded, which may be explained by a stable psycho-physiological state leading to confident piloting
Static and Total Pressure Sensor Development Methodology based on Elastic Sensing Elements and Optical Rules
Authors: Borisov R.A. , Antonets I.V. , Krotov A.V.
Published: April 2021

Information on the parameters of static atmospheric pressure and total pressure of the incoming air flow is the primary information in the air signal system, which is part of the integrated aircraft control system. This information makes it possible to calculate the altitude and speed of the aircraft for automated and automatic control. Static and total pressures are measured by aerometric parameter sensors, whose technical characteristics largely determine the range and values of the measurement accuracy of the air signal system. Relying on the requirements for aircraft flight safety and in accordance with the existing standards for horizontal and vertical separation, rather stringent requirements are imposed on the accuracy of air pressure measurement. Instrumental errors in measuring static and total air flow pressures with a probability of 0.95 should not exceed 0.02 and 0.05 % of the measurement range. The considered original aerometric pressure sensor based on an optical rule, whose high sensitivity requires minimal deformation of the elastic sensitive element, makes it possible to fulfill these requirements. The non-contact digital information retrieval and the operation of the information system under vacuum conditions significantly increased the efficiency of measurement processes. The paper focuses on an algorithm for calculating the main design parameters of elastic sensitive elements in almost the entire range of their standard sizes taking into account the technical capabilities of the secondary converter. The results of the experiments and experimental studies confirmed the sufficiency of theoretical methods for calculating the parameters of elastic elements for pressure sensors

Effect of Zinc Supplementation on Histomorphology of Testis and Epididymis in Male Wistar Rats
Authors: Kour Juneet , Devi Jonali , Sarma Kamal
Published: April 2021

Background: Bio potency of trace elements is very important in animal growth and reproduction. Among the trace minerals, zinc is very important as it is required for many normal physiological functions. It also plays an essential role in testicular steroidogenesis androgen metabolism and interaction with steroid receptors. Testes have a strict zinc requirement and severe zinc deficiency compromises spermatogenesis, sperm viability, motility and fertility in human beings. Zinc depletion studies in mice resulted in oligospermia with poor Leydig cell function and lowered testosterone concentration and was reversed by zinc supplementation. But, relatively few studies have been conducted on male animal responses to supplementation of important mineral like zinc at their critical phase of growth and reproduction. The present investigation was taken up to study the effect of zinc supplementation in two different doses with a view to assess its implication in testicular and epididymal sperm morphology during growth period in Wistar rats. Methods: The study was conducted in 72 weaned Wistar male rats for a period of 8 weeks from 4 to 12 weeks of age, which were procured from Indian Institute of Integrative Medicine, CSIR Laboratory, Jammu. The experimental rats were divided in to three groups as control: rats fed diet without zinc supplementation, T1 (treatment 1): rats fed diet containing zinc sulphate @ 50 mg/kg body weight/day and T2 (treatment 2): rats fed diet containing zinc sulphate @ 100 mg/kg body weight/day. They were provided standard pelleted ration and clean drinking water ad libitum and maintained under standard managemental conditions. On 6, 8, 10 and 12 weeks of experiment, the rats were sacrificed after induction of proper anaesthesia. The reproductive organs (testes and epididymidis) were collected from each rat and tissue pieces from testes and three parts of the epididymis viz. caput, corpus and cauda, were fixed separately in 10 per cent Neutral Buffered Formalin solution and processed for paraffin sections by alcohol- xylene method. Sections 5 μ thickness was stained by Haematoxylin and Eosin (Luna, 1968) for histological studies. Result: Elongated spermatids were seen in the seminiferous epithelium only in treatment (T1 and T2) groups at 6 weeks of age, not in the control rats. At 8 weeks of age, maximum number of spermatozoa were seen in the seminiferous tubular lumen in the T1 group as compared to T2 treatment group. At 10 weeks, spermatozoa were seen in the lumen of the seminiferous tubules in all the rats under study. The epididymis revealed no sperm pack in cauda epididymis in all group rats at 6 weeks of age. However, at 8 weeks of age, the sperm pack was seen in the lumen of the epididymal tubules of the cauda epididymis of T1 and T2 groups. The significant finding was that in T1 rats the sperm pack was very compact at 10 weeks in cauda epididymis as compared to T2 and control group rats.
Genesis of paradoxical features of kimberlites
Authors:   Institute of Geology of Diamonds and Precious Metals SB RAS, Shkodzinskiy V. S.
Published: April 2021

Based on the obtained evidence of hot heterogeneous accretion of the Earth and the calculated quantitative model of kimberlite magmas, the nature of the main features of kimberlites is explained. Their presence only within ancient cratons is conditioned by the crystallization of the magma ocean. The formation of kimberlites from residual melts in the bottom peridotite layer resulted in the enrichment of kimberlites with melt-like components, the presence of diamonds in them, the small volume of bodies and the scattered distribution. Decompression solidification of magmas at the shallow stage of ascent is the cause of the explosion under the influence of the preserved pressure of the gas phase and the absence of kimberlite lavas.
Physicochemical simulation of the conditions for the mafic granulite formation (Bunger Hills, East Antarctica)
Authors:   Saint Petersburg Mining University, Abdrakhmanov I. A.
Published: April 2021

The article presents the results of mineral thermobarometry and physico-chemical simulation of the formation of garnet-enstatite gneiss from the Mesoproterozoic metamorphic suite of the Bunger Hills, East Antarctica. As a result, the water activity, temperature and pressure of rock formation were estimated. It is shown that the peak temperature of metamorphism could reach 900 °С or more. Such temperature conditions indicate the prerequisites for the occurrence of UHT-metamorphism during the formation of the East Antarctic Shield.
From teaching experience. VII. Subordination of symmetry groups and crystallographic criterion of harmony
Authors:   Saint Petersburg Mining University, Voytekhovsky Yu. L.
Published: April 2021

It is shown by the example of the fences of Saint Petersburg that they combine the borders of all seven symmetry groups in different ways. A criterion is proposed: a lattice is harmonious if the symmetry groups of the borders are subordinate, otherwise it is eclectic. According to the author’s experience, such an approach on the border of crystallography and architecture facilitates the perception of the topic on the subordination of 32 point symmetry groups in the university course of crystallography. The article is dedicated to the memory of the outstanding scientist and popularizer of mineralogy Professor A. G. Bulakh.

Published: April 2021

L’objectif principal était d’évaluer l’impact d’un complément alimentaire, le Vitanimal (mélange de coques et de tourteau de coton), sur les performances laitières des vaches Borgou dans un contexte de rareté du fourrage en saison sèche et de réduction de la mobilité pastorale. L’évaluation a concerné un troupeau de 15 vaches ayant eu au moins deux mises bas à la Ferme d’élevage de l’Okpara. Les animaux ont été répartis en trois lots : le lot 1, lot témoin, a bénéficié uniquement du fourrage des parcours naturels et artificiels de la ferme, de pierres à lécher et d’eau ad libitum ; les lots 2 et 3 ont bénéficié de la même alimentation que les témoins avec en plus respectivement 2 et 4 kg du complément alimentaire. Les quantités de lait produites et les refus du complément ont été collectés et quantifiés chaque jour pendant 90 jours. Les analyses ont montré des différences significatives (p < 0,05) pour l’ingestion du complément alimentaire entre les lots 2 et 3, et pour les refus qui ont été plus importants dans le lot 3. Le Vitanimal a eu des effets significatifs sur les performances des vaches. Les productions journalières de lait ont été de 0,76 ± 0,35 kg, 1,04 ± 0,35 kg et 1,16 ± 0,46 kg respectivement pour les lots 1, 2 et 3. Ces quantités ont augmenté avec la quantité de complément servie. Toutefois, la ration du lot 2 a été plus rentable, soit 75 % de taux de rentabilité contre 25 % pour le lot 3.
