Mineral chemistry and geochronology of the Rajasthan emerald deposits, NW India
Authors: Alexandre Paul
Published: June 2020

The emerald deposits in Rajasthan, northwest India, are situated in a narrow NE–SW belt in the Aravalli Mountains. The studied deposits were formed by the metasomatic reaction between muscovite (± garnet ± tourmaline) pegmatites and lenticular bodies of altered ultramafic rocks that are hosted by the Delhi Group gneisses. This reaction produced phlogopite schists containing the exometasomatic emeralds, as in all other granite-related emerald deposits. Endometasomatic changes of the mineralogy of the pegmatites is indicated by the geochemistry of the muscovite (phengitic substitution) and the feldspars (disappearance of the potassic feldspar and calcification of the plagioclase).

The K-Ar analyses of syngenetic phlogopite (from the phlogopite schist) and muscovite (from the pegmatites) give an age of ca. 790 Ma, close to that of the last major orogeny affecting the region. This is in accordance with the ages of other granite-related deposits, which all formed in conditions of active orogeny. The ages of the biotite are lower than those of the muscovite, indicating limited radiogenic argon loss as a result of deformation.
THE PROBLEM OF SEXUAL EDUCATION OF CHILDREN AND YOUNG PEOPLE IN PEDAGOGICAL OPINION OF THE BEGINNING OF THE TWENTIETH CENTURY
Authors: Volikova
Published: June 2020

The article is devoted to the problem of sexual education of children and young people at the beginning of the twentieth century and its reflection in socio-pedagogical sources. In the publication the author reveals the peculiarities of sexual education of children and youth of the highlighted period, highlights the purpose, objectives and content of sexual activity education. It is proved that the problem of the study bothered as foreign, as domestic scientists (O. Bernstein, A. Gamme, A. Mol, A. Forel, E. Stil). The value of pedagogical ideas and experience of outstanding ones is substantiated educators and scholars who have dedicated their work to the problem of sex education of young people. In particular, the article found that since the beginning of the twentieth century scientists insisted on the need for a scientific approach to sexual education, which had to be aimed at eliminating the deep-rooted at a society of prejudice about many aspects of sexual life. Research results. The beginning of the twentieth century is a difficult historical one a period which was characterized by the presence of sufficiently controversial scientifictheoretical approaches to the problem of sexual education of young people. These differences of opinion related to statesmen, psychologists, educators and medical professionals. Increased attention to this issue was explained simultaneous effect of a number of objective economic factors (intensive industrial development, urbanization, population migration), scientific (medicine, biology, psychology) and sociocultural (deepening social stratification, family crisis, weakening of the educational role of the church, development of the feminist movement) development. All this contributed to the actualization issues of sexual education at the beginning of the twentieth century. Accordingly, the educational system in the sexual aspect functioned within traditional approaches that could not withstand the intensive development of medical and psychological sciences, so tried to use them for their own purposes. Necessity maintaining chastity before marriage was no longer religious or traditional guidelines, and medical and biological factors. It is proved that already at the beginning of the first decade of the twentieth century. Teachers have come conclusion about the need for systematic sexual education. However, it is education should not have been separated from the education system at all. The study has been hypothesized that built correctly and ethically sex education at school or in higher education will increase the level of literacy and awareness of pupils / students with sexual health and sexual development. Therefore, the problem of children and youth’s sexual education is one of the most urgent and socially significant in scientific discourse. Key words: education, sexual education, sexual life, sexual education, paternity and motherhood.

The sense of education-on of the main part in structure of educational process that is specified in knowledge system, skills and abilities, mastering which lays the foundation for development and the formation of student’s personality. So, pedagogic system review of the Volyn Gymnasium(Lyceum) the author begins by covering questions of purpose and content of it’s education, what significantly different from generally accepted standards. The organization of the educational process at the Lyceum was of a specific character. It was caused by the educational tasks of this institution, namely to provide its students with scientific knowledge appropriate to the level of European science development, to educate the young generation in love to their native land and respect for work. Regarding the forms of organization the educational process, it should be noted that the main form of its organization was the classroom lesson system. It should be noted that Lyceum educational programs was the attempt to connect humanitarian, natural and mathematical science. In addition the inspirational of the founders of the institution transform it in to university, aroused the desire of the teachers to create educational programs in the subjects taught at the Lyceum, close to university. So, the system of organizing the education of the Volyn Gymnasium (Lyceum) was quite holistic and had progressive ideas of the European level in the field of pedagogy. These include: - in-depth language learning at the initial stage of study (4 years); - paired teaching of subjects on the principle of affinity (Polish and Latin) and associativity (Italian language and music); - introduction into the course of study some separate subjects: history, geography, law and political economy; - the presence of a number of necessary subjects that developed students’ skills (prototypes of modern elective classes): mineralogy, bibliography, architecture, military construction; - additional riding, drawing, fencing, swimming, etc. In spare time; - various local activities of pupils under the teachers guidance; - the secular nature of teaching.
Heterogeneidad en el circuito superior de alimentos: empresas globales y empresas con anclaje en la formación socio-espacial
Authors: Busch Silvia Inés
Published: June 2020

En la Argentina y en las últimas décadas, los circuitos productivos de alimentos de rápida preparación han atravesado sucesivas modernizaciones que profundizaron la difusión del medio técnico-científico informacional en la formación socio-espacial argentina en general y en su área concentrada en particular. En esos procesos, distinguimos dos grupos de actores que conforman el circuito superior puro de la economía urbana: las empresas globales y las empresas con anclaje en la formación socio-espacial. En este artículo, daremos cuenta de su diferenciación a través del análisis de dos variables: el medio construido y las finanzas. Más específicamente, estudiaremos las formas en las que las divisiones territoriales del trabajo particulares se engarzan con el medio construido y el poder de los actores para entretejer círculos de cooperación en finanzas.

Ante los nuevos fenómenos característicos de la ciudad neoliberal contemporánea, se realizó un estudio centrado en las áreas verdes de nuevos proyectos inmobiliarios de las dos comunas con mayor población de la Región Metropolitana de Chile y del país: Puente Alto y Maipú. De este modo, el objetivo fue desentramar la relación entre la nueva oferta de vivienda y la presencia de áreas verdes. A partir de un estudio de información institucional se calculó la accesibilidad por proyecto comparándola con estándares internacionales y locales. Con los resultados, fue posible discutir acerca de las nuevas relaciones desiguales acerca de lo verde y la vegetación en la ciudad, específicamente en su periferia, siendo esta dimensión parte de proyectos de lujo, estableciendo una relación de mercado, excluyendo a quienes no puedan pagar por ella. De esa forma la producción de naturaleza urbana deja variados desafíos para una planificación urbana socialmente integrada.

We report the results of a ∼4 yr direct imaging survey of 104 stars to resolve and characterize circumstellar debris disks in scattered light as part of the Gemini Planet Imager (GPI) Exoplanet Survey. We targeted nearby (≲150 pc), young (≲500 Myr) stars with high infrared (IR) excesses (L
IR/L
⋆ > 10−5), including 38 with previously resolved disks. Observations were made using the GPI high-contrast integral field spectrograph in H-band (1.6 μm) coronagraphic polarimetry mode to measure both polarized and total intensities. We resolved 26 debris disks and 3 protoplanetary/transitional disks. Seven debris disks were resolved in scattered light for the first time, including newly presented HD 117214 and HD 156623, and we quantified basic morphologies of five of them using radiative transfer models. All of our detected debris disks except HD 156623 have dust-poor inner holes, and their scattered-light radii are generally larger than corresponding radii measured from resolved thermal emission and those inferred from spectral energy distributions. To assess sensitivity, we report contrasts and consider causes of nondetections. Detections were strongly correlated with high IR excess and high inclination, although polarimetry outperformed total intensity angular differential imaging for detecting low-inclination disks (≲70°). Based on postsurvey statistics, we improved upon our presurvey target prioritization metric predicting polarimetric disk detectability. We also examined scattered-light disks in the contexts of gas, far-IR, and millimeter detections. Comparing H-band and ALMA fluxes for two disks revealed tentative evidence for differing grain properties. Finally, we found no preference for debris disks to be detected in scattered light if wide-separation substellar companions were present.
The Effects of Metallicity and Abundance Pattern of the ISM on Supernova Feedback
Authors: Karpov Platon I. , Martizzi Davide , Macias Phillip , Ramirez-Ruiz Enrico , Kolborg Anne N. , Naiman Jill P.
Published: June 2020

Supernova (SN) feedback plays a vital role in the evolution of galaxies. While modern cosmological simulations capture the leading structures within galaxies, they struggle to provide sufficient resolution to study small-scale stellar feedback, such as the detailed evolution of SN remnants. It is thus common practice to assume subgrid models that are rarely extended to low metallicities and that routinely use the standard solar abundance pattern. With the aid of 1D hydrodynamical simulations, we extend these models to consider low metallicities and nonsolar abundance patterns as derived from spectra of Milky Way stars. For that purpose, a simple, yet effective framework has been developed to generate nonsolar abundance pattern cooling functions. We find that previous treatments markedly over-predict SN feedback at low metallicities and show that non-negligible changes in the evolution of SN remnants of up to ≈50% in cooling mass and ≈27% in momentum injection from SN remnants arise from nonsolar abundance patterns. We use our simulations to quantify these results as a function of metallicity and abundance pattern variations and present analytic formulas to accurately describe the trends. These formulas have been designed to serve as subgrid models for SN feedback in cosmological hydrodynamical simulations.

The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS are excellent for the asteroseismic study of solar-like stars. In this work, we present an asteroseismic analysis of the red-giant star HD 222076 hosting a long-period (2.4 yr) giant planet discovered through radial velocities. Solar-like oscillations of HD 222076 are detected around 203 μHz by TESS for the first time. Asteroseismic modeling, using global asteroseismic parameters as inputs, yields a determination of the stellar mass (

), radius (

), and age (7.4 ± 2.7 Gyr), with precisions greatly improved from previous studies. The period spacing of the dipolar mixed modes extracted from the observed power spectrum reveals that the star is on the red-giant branch burning hydrogen in a shell surrounding the core. We find that the planet will not escape the tidal pull of the star and will be engulfed into it within about 800 Myr, before the tip of the red-giant branch is reached.

The accuracy of Monte Carlo simulations in reproducing the scientific performance of space telescopes (e.g., angular resolution) is mandatory for a correct design of the mission. A brand-new Monte Carlo simulator of the Astrorivelatore Gamma ad Immagini LEggero (AGILE)/Gamma-Ray Imaging Detector (GRID) space telescope, AGILESim, is built using the customizable Bologna Geant4 Multi-Mission Simulator (BoGEMMS) architecture and the latest Geant4 library to reproduce the instrument performance of the AGILE/GRID instrument. The Monte Carlo simulation output is digitized in the BoGEMMS postprocessing pipeline, according to the instrument electronic readout logic, then converted into the onboard data handling format, and finally analyzed by the standard mission on-ground reconstruction pipeline, including the Kalman filter, as a real observation in space. In this paper we focus on the scientific validation of AGILESim, performed by reproducing (i) the conversion efficiency of the tracker planes, (ii) the tracker charge readout distribution measured by the on-ground assembly, integration, and verification activity, and (iii) the point-spread function of in-flight observations of the Vela pulsar in the 100 MeV–1 GeV energy range. We measure an in-flight angular resolution (full width at half-maximum) for Vela-like point sources of

and

in the 100–300 and 300–1000 MeV energy bands, respectively. The successful cross-comparison of the simulation results with the AGILE on-ground and in-space performance validates the BoGEMMS framework for its application to future gamma-ray trackers (e.g., e-ASTROGAM and AMEGO).
Disseminated Melioidosis Presenting with Community-Acquired Pneumonia: A Presentation Not to be Missed – A Case Report
Authors: Paul Shaun Wayn , Malek Khasnur Abd , Peter Alan Basil , Sidek Sabrilhakim
Published: June 2020

BACKGROUND: Melioidosis commonly presents with pneumonia and is associated with a high mortality rate. This case report discussed a case of confirmed disseminated melioidosis. The case focused on the chronological clinical progressions of melioidosis which initially masqueraded as community-acquired pneumonia (CAP) and subsequently developed into septicemia. This case report aims to create awareness among the primary care doctors working in a potentially endemic area for melioidosis to be vigilant of its non-specific presentation.
CASE REPORT: We report a case of an 80-year-old man who was treated for CAP and presented with unresolved fever and subsequently sepsis. A contrast-enhanced computed tomography showed disseminated lesions of varying sizes in the lungs, liver, spleen, and blood cultures grew Burkholderia pseudomallei. A pigtail drainage catheter was inserted into the liver abscess. In addition, the patient received a 46-day course of intravenous ceftazidime and a 4-month maintenance regime of oral trimethoprim-sulfamethoxazole and oral doxycycline.
CONCLUSION: Completion of antimicrobial treatment resulted in resolution of clinical signs and abscesses on imaging.

La eliminación de metales tóxicos presentes en efluentes líquidos mediante resinas de cambio iónico. Parte XII: Mercurio(II)/H+/Lewatit SP112
Authors: Alguacil Francisco José , Escudero Esther
Published: June 2020

El mercurio(II) puede ser eliminado de disoluciones acuosas aci­das mediante la resina de intercambio catiónico Lewatit SP112. Se ha investigado la influencia de distintas variables experimentales sobre la carga del mercurio(II) en la resina: velocidad de agitación (275–1000 min−1), temperatura (20–60 °C), valor de pH del medio acuoso (0–4) y dosificación de la resina (0.05–0.4 g·L−1). La carga de mercurio(II) en la resina disminuye con el aumento de la temperatura (reacción exotérmica) en un proceso espontaneo, mientras que el modelo de núcleo recesivo representa al mecanismo de carga del metal en el rango de temperaturas investigado. Los datos experimentales se ajustan al modelo cinético de segundo orden (275 min−1) o al modelo de pseudo segundo orden (500–1000 min−1), aunque la carga máxima del metal en la resina no depende de la velocidad de agitación. Los datos experimentales se ajustan a la isoterma tipo-2 de Langmuir. Se ha comparado la carga de mercurio(II) con distintas resinas y con nanotubos de carbono de pared múltiple. El mercurio(II) puede ser eluido con distintos eluyentes, pudiéndose obtener mercurio en estado de oxidación 0 a partir de las disoluciones de elución conteniendo al Hg(II).

Published: June 2020

Our society is transitioning from the industrial age to the digital age, thus also revolutionising the enterprise landscape. In addition, one can observe how the notion of economic exchange is shifting from goods-dominant logic to service-dominant logic, putting the focus on continuous value co-creation between providers and consumers. Combined, these trends drive enterprises to transform continuously. During enterprise transformations, coordination among the stakeholders involved is key. Enterprise models are traditionally regarded as an effective way to enable informed coordination. At the same time, the digital age also provides ample challenges and opportunities for enterprise modelling. The objective of this chapter is therefore threefold. The first aim is to reflect on the role of enterprise modelling for coordinated enterprise transformation. The second aim is to explore the challenges posed by digital transformations to enterprise modelling. The third aim is to reflect on how enterprise modelling itself may benefit from the new digital technologies.
Enterprise IT Operations
Authors: Vin Harrick
Published: June 2020

Over the past decade or so, for most enterprises, information technology (IT) has shifted from being a support function to be a synonym for business wellness. During the same period, though, the scale and complexity of IT for running business has grown significantly; today, performing any business function requires complex interplay of many, often invisible and dynamically changing, technology components. This is making design resilient and interruption-free IT a significant challenge. This chapter discusses limitations of traditional approaches for managing enterprise IT operations; introduces the concept of cognitive automation, a novel approach that blends intelligence with automation to transform enterprise IT operations; and describes the design of ignio™, a cognitive automation platform for enterprises. The author concludes by highlighting the challenges in driving cognitive transformation of enterprise operations and providing some suggestions for embarking upon this journey.

In this article there are presented materials regarding problems of infectious complications, that appear as the result of formation of microbial biofilms, which is especially actual in medical practice nowadays because of wide usage of different invasive materials in surgical and traumatological and orthopedical departments of clinics. Classifications, which are based on works of many authors, of surgical infections are given, and also of pathogens, known nowadays, of which Staphylococcus aureus и S. epidermidis are superior. Stages of process and laboratory-experimental proven time intervals and special features of biofilm’s formation are determined, which points to an importance and perspectivity of prophylaxis of infectious complications at moments of contaminations and primary adhesion. In light of usage in implantational surgery of constantly advancing materials, the contemplation is necessary of biofilmforming features of known pathogenic and opportunistic bacterias and potentially dangerous, in particular, pathogens that lead to generalization of process.
Results of the Experimental Research and Clinical Application of Cannulated Screw with Bioactive Coverage on the Basis of Natural Hydroxiapatite during Osteosynthesis of Medial Fractures of Femur’s Neck
Authors: Markov Alexander
Published: June 2020

The goal of our research is clinical-experimental justification of differentiated application of osteosynthesis methodicsand application of cannulated screw with bioactive coverage on the basis of natural hydroxiapatitefor patients of old and senile age with the medial fracture of femur’s neck (MFFN) with taking into account the stability grade of fracture by Pauwels classification and motional activity of patients before trauma. The present research is based upon clinical observation of 110 old and senile patients with supcapital and transcervical femur’s neck fractures. With the purpose of scientific justification and detailed research of different types of MFFN osteosynthses experimental stand tests were conducted with the use of cannulated screws and methodic of vertical ostesynthesis by H. Kuntscher for determining and comparison of density and strength of experimental systems “fixator-bone” in static regime over MFFN models. Cannulated screws with bioactive coverage on the basis of natural hydroxyapatite were applied for 16 patients among all operated by us. Time of rehabilitation of supporting and motional functions of the limb has been decreased by using these implants among patients with grades I and II (by Pauwels classification). Thanks to osteoinductive and osteoconductive features of bioactive coverage on the basis of natural hydroxyapatite, rehabilitation of operated limb’s function was conducted in shorter terms and faster rate. For the purpose of obtaining the dynamic stability of osteosynthesis and conduction of accelerated rehabilitation cannulated cervical screw was developed and applied in practice. This screw is different in the design of spiral part and the presence on its surface of bioactive coverage on the basis of natural hydroxyapatite.

Purple urine bag syndrome is a rare condition that occurs predominantly in the elderly, immobilized and bearer of chronic bladder catheter. It is a phenomenon usually associated with urinary tract infection, particularly in the presence of high bacterial load. The presence of alkaline urine, constipation, high-protein diet and dehydration are predisposing factors. In most cases it is an asymptomatic condition. We described the case of an elderly patient admitted to the geriatric Department in which purple urine was found in the urine collection bag. The culture of urine showed the presence of infection with Klebsiella pneumoniae. Targeted antibiotic treatment and proper hydration determined the resolution of the phenomenon and the resolution of the infection. Although it is an alarming phenomenon due to the particularity of the color of the urine, it is a treatable and solvable condition with an adequate specific antibiotic treatment. Prevention measures are equally effective and consist in eliminating the risk factors for this condition.

Authors: Ahangari Alebtekin , Abdolrahmani Mohammad
Published: June 2020

Kinesiophobia is one of the pain complications which eventually might cause disability. Several studies showed correlation between age-related problems with kinsiophobia. The objective was to investigate clinical trials about managing kinesiophobia among older adults aged +65 years until March 2020. PubMed, CINAHL, Google Scholar, and PsycINFO databases were electronically searched until March 2020. All studies about kinesiophobia, with clinical trials, and randomized trials study design among older adults aged +65 years were included in the review. Two set of searching terms including ‘kinesiophobia AND intervention’ and ‘fear of movement AND intervention’ were used. From a total of 2669 articles, after excluding for different reasons, only three articles with total of 87 participants, mean age 68.5, all from Turkey related to the objectives of this study remained. Two of them were evaluated using two different physiotherapy approaches to manage neck pain and low back pain and one of them was regarding falls. Kinesiophobia was used as measure for the effectiveness of treatments. Older adults with routine and properly designed exercise and activity are healthier, with a lower probability for disability and therefore higher quality of life and longer healthy life. But to reach those goals, agerelated diseases and barriers should be investigated.
Small, micro and medium enterprises financing: Costs and benefits of lending technologies in the Eastern Cape province of South Africa
Authors: Mbedzi Edson , Simatele Munacinga
Published: June 2020

Orientation: As lack of access to credit hinders small, micro and medium enterprises (SMMEs) success and lending technologies being conduits transmit credit access, more focus must be on the effect of lending technologies on credit rationing.Research purpose: To analyse the extent of credit rationing amongst SMMEs based on lender and firm characteristics.Motivation for the study: In South Africa, SMMEs are funded by different lenders using different lending technologies, but little is known about which ones are more effective.Research approach/design and method: The study takes a quantitative approach. In this study, 321 SMMEs are sampled from 1486 small businesses on the registers of the Nelson Mandela Bay Business Chamber and the Border-Kei Chamber of Business in the Eastern Cape province of South Africa. Financing of SMMEs is captured with a categorical credit-rationing variable. Accordingly, a logit technique is used. The first model captures credit rationing as a binary variable. In the second model, the nature of credit rationing is disaggregated resulting in a four-measure categorical variable.Main findings: Little rationing occurs when asset-based and venture capital methods are used. Microfinance and privately owned development financial institutions have high rationing levels, similar to commercial banks, defeating the purpose of their special existence to address excluded groups. Black people-owned and female-owned businesses are the most rationed. Credit rationing decreases with firm size, but the effects are amplified by race.Practical/managerial implications: To improve SMMEs access to finance, the government should focus on allocating funds to firms using SMMEs’ credit rationing risk profiles.Contribution/value-add: Lending technology, lender type and SMME characteristics relationships indicate that SMMEs can benefit from a well-understood rationing risk profile of firms in the economy. Therefore, policies on support and regulation of the distribution of loan portfolios aligned to empirical rationing risk profiles can improve SMME growth. However, this study has used SMME data from the Eastern Cape province only, one of the nine provinces in South Africa. Thus, the provincial heterogeneity effects are not captured in this study.
