Mobilidade estudantil de universitários oriundos do ensino médio público: experiências com o programa Ciência sem Fronteiras 1, 2, 3
Authors: Weller Wivian , Reis Jéssica
Published: July 2022

Resumo A internacionalização da educação superior é uma marca das universidades no mundo contemporâneo. Nesse processo, programas voltados à mobilidade acadêmica recebem centralidade, representando a faceta mais visível da internacionalização. O presente artigo analisa a mobilidade acadêmica de estudantes oriundos do ensino médio público no âmbito do programa Ciência sem Fronteiras, trazendo para a discussão o acesso ao programa, a experiência internacional e os projetos de futuro. A pesquisa foi conduzida em uma universidade pública da Região Centro-Oeste e consistiu na aplicação de dois surveys e na realização de grupos de discussão que foram analisados à luz do Método Documentário. Com base nos resultados, identificamos que a origem social e o capital escolar são dimensões que podem dificultar ou privar o acesso de estudantes de classes menos favorecidas em programas de mobilidade estudantil. Quando as barreiras são rompidas, as contribuições da experiência internacional ultrapassam os ganhos acadêmicos, possibilitando a abertura para novos projetos de futuro, tanto no campo pessoal quanto profissional.
Remote sensing and global databases for soil moisture estimation at different depths in the Pernambuco state, Northeast Brazil
Authors: Jucá Marcella Vasconcelos Quintella , Ribeiro Neto Alfredo
Published: July 2022

ABSTRACT The present study aimed to apply and assess an exponential filter that calculates the root-zone soil moisture using surface data from the soil moisture and ocean salinity (SMOS) satellite, as well as to assess soil moisture simulated in land-surface models from global databases. The soil water index (obtained after application of the exponential filter) and soil moisture simulated using land surface models (GLDAS-CLSM, GLDAS-Noah, and ERA5-Land) from global databases were compared with in situ data to evaluate their efficiency in estimating soil water content at different depths. Surface measurements from the SMOS satellite allowed the estimation of soil moisture at depths of 20 and 40 cm by applying the exponential filter. At both depths, the application of the exponential filter significantly improved the estimation of soil moisture measured by the SMOS satellite. The GLDAS-Noah model had the best root mean square error values, whilst the GLDAS-CLSM and ERA5-Land models overestimated the soil moisture. Nevertheless, the seasonal variation was well represented by all land surface models.

Rock burst forecasting technique and selecting a safe coal face advance direction
Authors: Kobylkin S. S. , Pugach A. S.
Published: July 2022

Mine planning involves selecting an optimal mine layout. At the same time key factors, including those influencing mining safety, should be comprehensively taken into account. A developed rock burst forecasting technique taking into account mine workings of an extraction area and a mine goaf enables determining the safe direction of a coal face. The proposed technique also takes into account all faulting/joint systems, occurring beyond a mine field. The distribution of specific potential energy in an intact rock mass is proposed to be used as the basis of the input data required for rock burst forecasting. The forecast is carried out via estimating the Lode-Nadai coefficient at different directions of coal face advancing. The stress (intensity) coefficient is proposed to be used as a criterion in order to determine a safe direction. We determined the safety criterion is equal to 10 in the Komsomolskaya Mine conditions. Besides, the safest direction of a coal face advance to mitigate the risks of rock burst was determined for this mine. The direction between 138° and 128° counter-clockwise from the north direction was identified to be the safest for the Komsomolskaya Mine conditions for any values of deformation modulus and Poisson’s ratio.
Controlling blast energy parameters to ensure intensive open-pit rock fragmentation
Authors: Nasirov U. F. , Zairov Sh. Sh. , Mekhmonov M. R. , Fatkhiddinov A. U.
Published: July 2022

Controlling blast action, in order to increase its energy efficiency in a production blasthole is quite an important issue. This is because it enables the formation of broken rock mass with preset coarseness parameters. Increasing the blast pressure and the time of the blast impact on a rock mass is traditionally recommended as one of the ways to improve the blast action on the rock mass, thus reducing the oversize yield in open pits. One device which enables this approach to a certain extent is a turbulator. The turbulator is fabricated of aluminum plate twisted in a helical fashion around its longitudinal axis. It is mounted in a production blasthole according to a specially designed scheme. The methodology developed to study the stress and strain state of a rock mass when using a turbulator in a blasthole explosive charge allows the size of radial fracture zone and the radius of rock fragmentation to be defined. A method was developed to initiate blasthole charges in a pit blasting block. It includes drilling blastholes, filling them with explosive, installing downhole blasting caps, and blasting using non-electric initiation system. A blasting block is divided into two equal parts (sections), which in turn contain three series of blastholes for short-delay blasting. Blasthole charges are initiated simultaneously in the two parts of the block based on a trapezoidal blasting pattern, thus ensuring meeting detonation waves. In the first series, instantaneous blasting of blastholes located on both ends of the blasting block and forming a trapezoid (in plan view) is carried out. Then after 42 ms, the second series of blastholes (also forming a trapezoid) is detonated. After another 42 ms, the remaining blastholes are detanoated along the perimeter of the blast block in the third series. Implementation of this design with the effect of turbo-blasting for rock fragmentations by blasthole charges at the Kalmakyr deposit of JSC “Almalyk Mining and Metallurgical Complex” has led to the reduction of consumption of explosives, volume of drilling, secondary fragmentation costs, and increased productivity of excavators and mining safety.
Justification of geometrical parameters of lining plates for a belt conveyor drive drum
Authors: Ziborova E. Yu. , Mnatsakanyan V. U.
Published: July 2022

Belt conveyors are widely used in mining industry in open-pit and underground mining for moving bulkload in horizontal and inclined directions to the sites of processing. In order to create the best conditions of frictional contact between a belt and a drum, various methods of drive drum lining are used. The main lining material is rubber of different grades, providing proper coefficient of friction of a belt with a drum (within the range of 0.6–0.62). A drive drum lining material must have high wear resistance, thermal resistance, mechanical strength, ability not to accumulate electric charges on the surface and not to generate dangerous concentrations of toxic components (for example, chlorine gases, carbon monoxide) when heated. The use of ceramic lining opens up great opportunities for increasing lining durability and useful life of high capacity heavy-duty conveyors. The paper presents the results of the study of stress-strain state of belt conveyor drive drum ceramic lining plates. We used Solid Work Simulation environment in the study on the basis of the accepted analytical model of plate-belt contact for drive drum with diameter D = 1250 mm, belt width L = 1000 mm, and the belt entering branch tension value Se = 25400 daN with regard to the value, direction, and nature of the acting loads. On the basis of stress-strain analysis of alumina ceramics lining plates, the favorable geometrical parameters of the plate cleats (projections) and the required properties of lining material ensuring the proper load-carrying capacity at the contact with the belt rubber facing were found. It was established that a plate cleat diameter for heavy duty conditions should be not less than 4.5 mm and its end round R should be within the limits of 0.5–0.6 mm, and, in the base, 0.3–0.4 mm at a cleat height of 1.0–1.4 mm in order to prevent stress concentration in hazardous sections. It was also established that alumina ceramics bending strength must be no less than 350 MPa for effective functioning of rubber-ceramic lining. Simulation of a plate stress-strain state on exposure to alternating loads made it possible to identify characteristic areas with maximum stress concentration, which were foci of crack nucleation. Thus, it became possible to predict lining useful life.
VR/AR technologies and staff training for mining industry
Authors: Vavenkov М. V.
Published: July 2022

Personnel working at mining enterprises must be prepared to overcome professional difficulties and to possess the professional competencies required not only for the implementation of processes, but above all their safety. Modern digital modeling technologies used in mining activities expand the boundaries of practical training not only for future mining engineers, but also for working specialists. As part of the training process, it is important that the simulation of the mining environment be of a high quality almost indistinguishable from the actual environment. In this context, the development of process solutions based on virtual and augmented reality (VR/AR technologies) is most relevant. Process automation in the conditions of large-scale digital transformation laid the foundations for the development of VR/AR in mining industry. Data analysis shows that VR/AR technologies are the major consumer of IT solutions. They are in fact the integrator, or the highest “IT-transformation”, which in practical terms create digital parallel production objects and processes. Further developments in this area may also change some of the existing traditional entities or create new ones, in the training system as well. An example of such an entity, on which the digital future will depend, is the emerging “digital culture”. As such it will be applicable not only in the corporate, industry, but also nationally. Despite the diversity of areas in the development of VR/AR technologies, the maximum effect of their implementation is manifested in the development of special skills of personnel in equipment operation. This clearly relates to the need to ensure the efficiency and reliability of technological operations and processes. The interaction between the consumer and producer of VR/AR solutions together with universities allows a number of problems related to the formation of competencies in the future generation of specialists to be resolved. These include: training of university graduates; creation of specialized courses in educational programs; individual higher educational programs; professional development and retraining courses for specialists in the field of VR/AR technologies in mining; involvement of the academic community representatives in the development of practical tasks based on VR/AR solutions, including researchers of different specializations (geology, geophysics, geotechnics, geoinformatics, aerology, geotechnology, mining machinery and equipment, automation, etc.). Other key areas include the dissemination of the best practices of VR/AR usage in the interests of future customers; creation of a common method to assess the effectiveness of VR/AR projects to determine their investment attractiveness; as well as prediction and creation of future technologies.
Substantiation of pillar parameters in mining of inclined coal seams in Quang Ninh Province, Vietnam
Authors: Nguyen V. N. , Pham T. N. , Osinski P. , Nguyen T. C. , Trinh L. H.
Published: July 2022

Design and operation of auxiliary underground workings in coal mines involves substantiation of parameters of coal pillars and requires development of new approaches to substantiate their geometrics. On the one hand, sufficient stability of a “rock mass – working – coal pillar” system should be ensured. On the other hand, the parameters of “frozen” coal reserves in the pillars should be justified. The joint solution of these two problems requires accurate forecasting based on modern digital models of a rock mass. In this study, a model of rock mass and mine workings with different dimensions of a coal pillar is presented with the use of Flac3D software. The simulation findings showed that when developing sloping coal seams, the volume of coal extraction in a longwall has an effect on the stress-strain state of the enclosing rock mass. During the study different factors having effect on geometrics of a coal pillar were analyzed, and their influence on the field of stresses and shear of inclined layers in a rock mass was studied, and the size of the plastic deformation zone around an auxiliary mine working was also determined. The study findings are also of practical importance in terms of substantiating the parameters of a working support design. The size of coal pillar is also connected with the support type. It should be taken into account that bolts should be of sufficient length to ensure firm fixing and located in the zone of intact rocks. The research showed that a coal pillar should be 10 to 15 m wide in order to ensure optimal mining conditions and safety.

La narcotización del mundo será la propuesta temática central de este número de Cultura y Droga. Se trata tanto de una propuesta conceptual como de un supuesto de investigación que empezamos a trabajar hace tres años al término del tercer Congreso Carl Lumholtz en la ciudad de Chihuahua, México. Hoy, tras un periplo plagado de reuniones y nuevos congresos , ofrecemos avances teóricos y materiales empíricos cuyo trasfondo reflexivo y analítico está perfilado por tres nociones constitutivas del postulado inicial: el desencantamiento del mundo, el proceso de alcoholización y el proceso de normalización. Progresivamente, asistimos a una diversificación de sustancias y combinaciones de estas con otras ya consolidadas en las prácticas sociales de consumo narcótico en nuestro entorno latinoamericano, así como mundial. También está documentado el incremento exponencial en las cantidades comercializadas con registro sanitario o no. En suma, la vida cotidiana de la humanidad incorpora más cantidad y diversidad de sustancias narcóticasmientras que, por otra parte, las políticas públicas y los discursos dominantes en torno a estos productos y las prácticas socioculturales asociadas a ellos redundan desde hace décadas en la abstinencia o supresión de los consumos ante un fenómeno definido por defecto como problema social.
Usos de drogas, biocodificación del género, y sexualidades disidentes-minoritarias. Entre el pánico moral y la narcotización de la sexualidad
Authors: Deheza Gargiulo Rocío del Pilar
Published: July 2022

Desde los aportes teóricos de Preciado (2020) sobre el régimen farmacopornográfico, de Martínez-Oró (2015) sobre la normalización de los consumos de drogas, y la propuesta de Ibán Trapaga sobre el proceso de narcotización de la vida cotidiana, esbozamos aproximaciones a los procesos narcotizantes vinculados a la modulación de la tecnosexualidad, las prácticas sexuales disidentes-minoritarias y la biocodificación del género. A partir de una perspectiva histórica, se busca comprender las fuerzas que median en los procesos de narcotización de la sexualidad y de politización de los usos de drogas y de las sexualidades. A modo de ejemplo, se presentarán brevemente dos casos: las prácticas de chemsex y el uso de hormonas sexuales y esteroides anabólicos. Proponemos que el proceso de narcotización sobre la sexualidad de las personas puede entenderse como una forma de autoafirmación y resistencia, como una estrategia de sanación ante las heridas que el cisheteropatriarcado provoca en nuestros cuerpos.
“No soy vendedora de medicamentos, soy médico”. La prescripción médica en los consultorios adyacentes a farmacias, juego de tensiones y negociaciones
Authors: Morán Pérez Ana Victoria
Published: July 2022

Con la expansión de los consultorios adyacentes a farmacias (CAF) en México, surge la necesidad de indagar cómo ocurre la prescripción de  medicamentos en estos establecimientos, ello a causa de la consustancial vinculación entre consultorio y farmacia, característica central de los CAF. Este artículo tiene el objetivo de describir las prácticas de prescripción en consultorios adyacentes a farmacias ubicados al sur de la Ciudad de México, y analizar las determinantes que influyen en éstas, así como los significados que el personal médico atribuye a esta actividad. Se utilizó una metodología cualitativa bajo la cual se realizaron entrevistas a profundidad y conversaciones informales que recuperan las perspectivas de 22 médicos sobre el acto prescriptivo. Se muestran los factores que determinan los criterios para prescribir, la existencia de posibles conflictos de interés y las tensiones- negociaciones —entre médicos, pacientes, dispensadores y propietarios de la farmacia— que están articuladas en torno a los medicamentos. Las conclusiones apuntan a que los CAF son un espacio donde convergen actores con intereses y expectativas diferenciales pero que comparten un referente en el medicamento, en tanto objeto-proceso polisémico y multidimensional. Asimismo, se concluye que estos consultorios cumplen una función doble: brindar atención a la salud, a la vez que constituirse como nuevos mercados de consumo farmacéutico.
The factors of marketing channel selection of queen pineapple farmers in Camarines Norte
Authors: Campita Maria Christina F. , Tokuda Hiromi , Sales Hector M.
Published: July 2022

ABSTRACT
Purpose - Pineapple cultivation provides sustainable livelihood to many smallholder farmers in developing countries like the Philippines. However, income is affected by the selection of marketing channels. This article assessed the factors affecting the selection of marketing channels of Queen Pineapple farmers in Camarines Norte.
Methodology - A mixed data collection process was used, including semi-structured questionnaires and key informant interviews. Primary data gathered from 96 randomly sampled farmers and 32 purposively sampled buyers were used to characterize the nature of the channels. Profitability was measured by calculating the marketing costs, net profit, and profit margin per channel. The Chi-square statistics were used to test the influence of socio-economic variables on the marketing channels, while descriptive statistics were used to interpret the factors affecting the selection of marketing channels.
Findings - Among the five identified channels, respondents preferred the wholesaler channel despite low profitability. Quick cash was identified as the major factor in the selection of marketing channels. A significant relationship relative to marketing channels was traced to the interplay of the following key factors: gender, civil status, location, and sources of income. Profitability analysis dictates that the optimum channel for farmers is the direct channel, but requires higher capital for added marketing costs. Income analysis showed that the majority of the farmer respondents were living below the poverty threshold.
Conclusion – Financial pressures hinder most pineapple farmers from choosing the most profitable channel. It is hereby recommended to sell via direct channel by batch through synchronized harvesting; adopt a multi-crop pineapple production system to maximize land utilization; secure off-farm employment for an added source of capital and income; explore a joint marketing system to sell in bulk inside and outside the province; seek logistical and technical assistance from the LGUs, cooperatives, and DA to strengthen market linkage; and adopt the value chain concept to add value to the product.

Relationship between domestic logistics opportunity efficiency and international logistics opportunity efficiency based on market potential: empirical research on developing countries
Authors: Kara Karahan
Published: July 2022

Purpose- This research has two main purposes. The first purpose is to determine the domestic and international logistics opportunity efficiency levels based on the market potentials of developing countries. The second purpose is to determine whether the domestic logistics opportunity (DLO) efficiency of developing countries has a significant effect on the international logistics opportunity (ILO) efficiency.
Methodology - Two basic analysis techniques have been applied in this study. In the first analysis, two output-oriented data envelopment analysis (DEA) models have been developed to determine the DLO and ILO efficiency of developing countries. The data of the input variables are taken from the Market Potential Index (MPI) 2021 report. Data for output variables are taken from the Agility Emerging Markets Logistics Index (AEMLI) 2022 report. In the second analysis, simple regression analysis has been applied to determine the relationship between DLO efficiency and ILO efficiency. The sampling consists of 45 developing countries.
Findings- According to the DEA Model-1, the DLO efficiency of 26 developing countries has been determined at the full efficiency level. 19 countries are not at the full efficiency level. According to the DEA Model-2, the ILO efficiency of 31 developing countries has been determined at the full efficiency level. 14 countries are not at the full efficiency level. According to the simple regression analysis findings, DLO efficiency has a positive and significant effect on ILO efficiency.
Conclusion- It has been determined which country should focus on which input variable for the developing countries that are not at the full efficiency level to reach the full efficiency level. It has been determined that the DLO and ILO efficiency of five countries are different. Empirical evidence has been obtained that the steps to be taken to increase the DLO efficiency will also increase the ILO effectiveness.

Authors: Gunes Evrim , Sekerdil Resat
Published: July 2022

Purpose – The purpose of this study is to reveal the entrepreneurial and innovative behavior tendencies and skills of Y and Z generations based on experiences and perceptions, and to provide an understanding of the problems these generations face while collaborating and the needs necessary for their cooperation.
Methodology– In order to obtain in-depth information about the subject, the qualitative research method was used in the research. Semi-structured interviews were conducted with the entrepreneur mentors of Ege University Technopolis and the entrepreneurs in the technopolis. The sample consists of 8 people in total. The data were analyzed with descriptive and content analysis.
Findings – The expressions of the participants were evaluated under the themes of entrepreneurship and innovation skills of the Z generation and the entrepreneurship and innovation perceptions of the Y generation, which emerged as a result of the analysis. Entrepreneurship and innovation skills for the Z generation; being a researcher, being aware of what one wants, agility, social relations, being able to offer different suggestions, self-confidence, being open-minded, being open to learning, being result-oriented, being proactive, taking risks, having business management knowledge. For the perception of entrepreneurship and innovation of the Y generation; commercial perception, innovation barriers, time, scaling, realism, and result-oriented qualities came to the fore.
Conclusion – Entrepreneurship is often defined in terms of risk taking, self-confidence and proactive behavior. These general behavior patterns are not well understood in entrepreneurship and innovation surveys. There are many more factors to be discovered for scaling these concepts. In this study, it was revealed that in order to be an entrepreneur, it is necessary to be innovative first, and being innovative is related to openness to learning and frequency of experimentation in addition to general behavior patterns.

). Moderating impact of the board of directors on environmental accounting and market reactions in South Africa
Authors: Amon Bagonza , Chen Yan , Rech Frederik , Aliyi Abdurahman
Published: July 2022

Purpose-The UN environment challenge 2030 was set to develop and enhance approaches to sustainable development. The study was carried out to investigate the impact of environmental accounting on market reactions in Africa and more so the moderating impact of the board of directors on the said relationship.
Methodology- The study used 119 listed firms on the Johannesburg stock exchange with the period spanning 2008-2019. We used Investment variable regression model for the study using share price and adjusted market returns as proxy for market reactions and environment accounting as reported in annual integrated reports as a proxy for environmental accounting
Findings- Results obtained show that environmental accounting has a positive and statistical relationship with market reactions and the board of directors does moderate the relationship between market reactions and environmental accounting. The study shows that firms in South Africa are taking sustainability accounting correctly by accounting for the environment. This supports the legitimacy theory and also supports the notion that firms are taking the lead in climate change consideration. We are the first to make such a study in an African setting and thus we hope that regulators will pay more attention to the reports and workings of firms and their contribution to the environment.
Conclusion- The study supports stakeholder and legitimacy theories as it shows that directors carry out decisions for the benefit of all stakeholders, and firms carry out decisions to prove their legitimacy in fulfilling their societal obligations which include taking care of the environment as any responsible citizen would. In order to achieve the UN environmental goals of 2030 of a cleaner environment, we need everyone on board including firms, investors and the public. Investors can help push firms be more sustainable and take care of the environment in which they operate by refusing to buy the assets of firms engaging in pollution or purchasing assets for firms that are environmentally compliant.

Circular Economy: The future in sustainable cities
Authors: Matsumura Cecilia Emi Yamanaka , Ramos Heidy Rodriguez , Dias António José Guerner
Published: July 2022

Cities are like living organisms that, to function, need resources and goods such as energy, raw materials, water, and food. After being used, the surplus of these resources is discarded, being directly responsible for most of the environmental impacts caused by human actions on the planet and not only in the territory where urban agglomerations are concentrated. Circular Economy arises to meet the need to reverse and contain the current scenario of exhaustion of natural resources and loss of biodiversity, introducing sustainable production and consumption. Its concept has been explored by different segments of society such as industries, academia, NGOs, government entities, among others, with multiple approaches and applications. Thus, this article, from a theoretical framework, explores the origins of the Circular Economy concept, providing a review of the main schools of thought that preceded it, and analyzes the common point of view on the Circular Economy concept. The article also identifies some scenarios in Brazil and in the world, whose countries and regions have stood out for their representativeness in the global context. It concludes with an insight on the current “status”, the future, and transition to Circular Economy.
Socio-environmental vulnerability as a consequence of urban problems in Brazil: An overview
Authors: Gonçalves Elton de Oliveira , Grigio Alfredo Marcelo , Souza Neto Luiz Tavernard de , Diodato Marco Antonio
Published: July 2022

The expansion of human occupation over the limits of cities leads to the depletion of infrastructure, impacts on its dynamics and imposes mobility difficulties. This type of territorial occupation results in urbanization patterns that undermine equity, efficiency and the continuity of the city as a support for social life. Therefore, this article aims to reflect on the importance of socio-environmental vulnerability in territorial planning and its use to guarantee the social function of the city. In order to reach the objective, an integrative review was used using the following questions: What approaches have guided the approaches to socio-environmental vulnerability in undergraduate and graduate courses? What are the methodologies for applying socio-environmental vulnerability that can be identified in the publications? For the selection of articles, the Scientific Electronic Library Online (SCIELO) database was used. It can be seen that research on socio-environmental vulnerability has contributed satisfactorily to the importance of this topic in Brazil, which allows progress through the use of new techniques and tools, which enabled a favorable diagnosis of socio-environmental vulnerability factors in the country. Brazilian context. However, it was found that in Brazil there is great potential to make a qualitative leap in several areas, including the issue of territorial planning, which should associate measures of an ethical, social, economic and environmental nature that carry out the maximum of Brazilian environmental legislation. With regard to land use and occupation, there is still a lack of awareness for an orderly, balanced and fair occupation.
Fragments of green infrastructure: the case of the Tijuco Preto stream in São Carlos, São Paulo, Brazil
Authors: Borchers Tatiane , Figueirôa-Ferreira Victor Garcia , Fernandes Ricardo Augusto Souza
Published: July 2022

The growing and accelerated Brazilian urbanization has caused several adverse effects, among them the channelization of streams and rivers, often seen as a sign of progress. This urbanization and the worsening of climate change increases the magnitude of the threats to urban areas. The planning of green infrastructure seeks to integrate nature with the city, favoring the mitigation of environmental impacts and allowing greater adaptation and resilience in facing the problems caused by climate change. In this context, this study sought to analyze the renaturalization of a section of the Tijuco Preto stream, in the city of São Carlos, São Paulo state, Brazil, as a green infrastructure strategy and to contrast this section with the others, composed of gray infrastructure. The stream was divided into three study sections: (i) section 1 – renaturalized; (ii) section 2 – buried; and (iii) section 3 – channelized. Section 1, despite presenting the best environmental conditions of the whole stream, is configured as a fragment of green infrastructure that, alone, cannot mitigate all the impacts of adverse events downstream, such as floods. Thus, it is necessary to integrate this space with other equipment and green spaces, as well as expand the renaturalization initiative to the other sections.

Additional fossil specimens of Eophylica (Rhamnaceae) in mid-Cretaceous amber from the Hukawng Valley, Myanmar
Authors: Poinar, Jr. George O. , Chambers Kenton L.
Published: July 2022

The recently described fossil angiosperm genus Eophylica (Rhamnaceae) was based on 18 amber-embedded specimens derived from two sites in northern Myanmar. A vegetatively similar fossil, which came from the same amber mines but which lacked flowers, had been previously described as a putative green alga and given the name Electrophycus. The dimensions and vegetative aspect of that taxon’s holotype specimen are identical with those of the Eophylica fossils. Four additional specimens were acquired by the senior author after the publication of Electrophycus, all of which have a single terminal flower that is either immature or essentially fully formed. Using techniques of floral dissection, high magnification microscopy, and microphotography of the better-developed flowers, we present a more detailed picture of the floral organs, especially the stamens and style, of Eophylica. These flowers differ from the holotype specimen of Eophylica and 3 of its paratypes in that they possess involucral bracts of a so-called ‘pseudanthial head,’ a structure that the authors of Eophylica had only ascribed to certain other paratype specimens of the genus.

Dr. Pinkava mentored 35 students as chair or co-chair, including seven Ph.D. students, many of whom have launched their own academic careers (see list of graduate students at the end). He published generously with his students on Cactaceae, the Flora of Arizona and documenting new chromosome counts for both (see bibliography below).
On the origin of the two putative allopolyploids, Opuntia curvispina and O. martiniana (Cactaceae): A case of cryptic speciation in prickly pear cacti
Authors: Majure Lucas C.
Published: July 2022

The putative allopolyploid taxon, Opuntia curvispina, is distributed from northeastern Arizona and southern Nevada to southeastern California, where it often grows in close proximity to, or sympatric with, O. chlorotica, O. engelmannii and O. phaeacantha. Another putative allopolyploid, O. martiniana, grows sympatrically with O. curvispina in only one area north of the Hualapai Mts., northwestern Arizona. Both of these taxa have previously been treated as either nothospecies or mere spontaneous hybrids by previous researchers. My objectives were to determine the origins of both O. curvispina and O. martiniana to test previous hypotheses of hybrid origin, with O. curvispina putatively derived from O. chlorotica and O. phaeacantha and O. martiniana putatively derived from O. chlorotica and O. engelmannii. I also wanted to determine the overall extent of the ranges of the two taxa by expanding collections and verifying existing herbarium collections, as numerous specimens identified as O. martiniana and O. curvispina have been reported from outside of their expected ranges. My data indicate that O. curvispina indeed is partially derived from O. chlorotica, as well as another putative parent, likely O. phaeacantha, while O. martiniana appears to be most likely derived from O. curvispina and O. macrorhiza, two taxa not before implicated in the origin of O. martiniana. The hexaploid O. phaeacantha also appears to be non-monophyletic and may have been derived several times from different hybridization events. Careful morphological study of O. martiniana clearly separates that species from O. curvispina, although it may be considered cryptically different, a likely result of its partial putative origin from O. curvispina. Given the very broad distribution and dominance of O. curvispina in parts of its range, it is most appropriate to recognize this allopolyploid as a species, rather than as a nothotaxon, as previously designated. The unique feature of an obovate or urceolate style in Opuntia martiniana appears to be a transgressive trait rather than a synapomorphy, given that the taxon is derived from reticulation, and neither putative parent exhibits that character state. This work provides a framework for species recognition using DNA sequence data, morphological characters, geography and cytological information—a total evidence approach clearly needed for taxonomically difficult taxa, such as many within the genus Opuntia. A treatment of O. curvispina and O. martiniana is given with updated descriptions, and O. martiniana is neotypified.

Published: July 2022

Cemento-ossifying fibroma is a rare benign fibro-osseous neoplasm commonly involving the jaws majority of lesions occur in mandible bone. It can be discovered as an incidental finding in radiological imaging. Symptomatic patients are presented with a slowly growing mass involving the jaws commonly in mandible bone and can attain a large size with the passage of time. It can cause facial deformity if left untreated. We present such a case of Cemento-ossifying fibroma involving the right hemi-mandible bone, and its radiological imaging findings, including X-ray (OPG), CT scan, and Histopathology.
Targeted delivery of therapeutic oligonucleotides in pancreatic cancer
Authors: Iris Yang
Published: July 2022

Currently, the most common treatment options for pancreatic cancer include chemotherapy, radiation, and surgery. These treatment options are not specific to the cause of the disease and therefore result in a large number of side effects including nausea, fatigue, hair loss, etc. The use of oligonucleotides may be a more efficient and safe method of cancer therapy. This mini-review will cover how oligonucleotides have been used to treat diseases in the past as well as different methods for delivery into the body and finally the applications of oligonucleotides in pancreatic cancer therapy.

We present a hypothesis for low vitamin D as a sign of untimely relocation of the human being during its history. This improper displacement prone our species to infectious and non-infectious diseases during our life journey, low vitamin D is a sign that needs to be addressed as a marker of the unsafe journey in our lifetime not the cause for diseases that are associated with it and replacement of vitamin D is the least that we have done.
