Resource Allocation and Mode Selection in 5G Networks Based on Energy Efficient Game Theory Approach
Authors: Tiwari Amit Kumar , Mishra Pavan Kumar , Pandey Sudhakar , Teja Panduranga Ravi
Published: December 2022

With the advent of next-generation cellular networks, energy efficiency is becoming increasingly important. To tackle this issue, this paper investigates energy efficiency in D2D-enabled heterogeneous cellular networks. Boosting the longterm energy efficiency of wireless 5G communication networks is being explored through mode selection and resource allocation. The study proposed a three-stage process for energy-efficient mode selection and resource allocation. The process starts with cellular users who switch to D2D emitting a beacon and cellular users within close proximity reacting to it. A proposed auction mechanism will be enacted inside the group in the second state ( in this paper, the group size will be four). Next, each cellular user was classified according to SINR values, distance, and battery life, so that they could dynamically transition between standard cellular mode and D2D mode. For stage three, direct-hop hybrid D2D communication, we developed a TAMM double auction game model that efficiently splits resources. To identify the true bidders in our game model, we compute the median and mode values of the ASK and BID values received by both seller and buyer cellular users. A simulation study shows that the proposed method is energy-efficient in a heterogeneous network enabled by D2D.
Revisiting “Citizenship Under Fire“
Authors: Ben-Porath Sigal
Published: December 2022

This short essay relates the impact of war on democratic and civic education to similar impacts generated by persistent polarization and extremism. Some misguided responses to both are discussed, especially those that entrench nationalistic sentiments and undermine democratic attitudes, as well as responses focused on singling out some identity groups as suspect. A normative case is made for addressing conspiracism and polarization through an intentional effort to build a civic community committed to sound epistemic practices.
On Education of Generations in History
Authors: Yakovlyeva Vita
Published: December 2022

This article is an attempt to bring children and youth to the forefront of debates on public education during war as actors of both education and its future. To do so, it relies on theoretical reflections on generations in history, especially pertaining to generational gap, conflict, and social change as produced intergenerationally. These primarily theoretical ponderings are grounded in the war-torn contemporary Ukraine, as well as the student actors of its recent educational reform entitled the New Ukrainian School.
‘Total War,’ ‘People’s War,’ ‘Wars’ of Inequality and Education in South Africa
Authors: Chisholm Linda
Published: December 2022

Wars, whether of full-scale invasion and military aggression or on a lower scale of intensity, destroy educational infrastructure and aspirations. But during war, education can also hold out the possibility for alternatives. Using South Africa in the 1980s as a case of low-intensity war, this article shows how parts of the system became militarised but also how an alternative vision was created through and in education. Nationalism, militarism and gendered identities romanticising war and violence were closely linked in white schools. For black youth, militarism became a defence against state violence. Apartheid was defeated, but the violence produced by the conflict has lived on in the society in different ways. Redrawing the boundaries of the nation after apartheid has created new Others. Education can and must continue to create the possibilities for thinking about different ways of organising society and looking to a future without war.
Educating the new Soldier in Post-Fascist Germany: The Example of “The soldier’s Everyday Life” (1957)
Authors: Berner Esther
Published: December 2022

The article deals with the role that the military should play as a socialization instance in the decades immediately after World War II. Even today, as the example of the German Federal Armed Forces (Bundeswehr) shows, armies claim not only to train but also to educate their soldiers. The Bundeswehr as well as other military organisations, however, have only received little attention in research in the history of education. The case of the Bundeswehr is interesting with respect to issues and concepts of military education, socialization, and discipline because rearmament in the postwar West German context was in particular need of political justification. Above all, after 1955 it was necessary to recruit volunteer soldiers. To this end, the Bundeswehr resorted to films as well as other media. One such promotional film, entitled "The Soldier's Everyday Life," will be used to show how the idea of the new democratic armed forces was presented to the population.
Third National Summit on Promoting Well-Being and Resilience in Healthcare Professionals: Abstracts from the Poster Winners
Authors: Building Healthy Academic Communities BHAC Journal
Published: December 2022

Symptoms of burnout, depression, and anxiety are experienced by more than half of all healthcare providers across the country. Like the general population, healthcare providers also engage in unhealthy lifestyle behaviors which can contribute to suboptimal mental health and chronic disease outcomes. Further, the mental and physical well-being of providers has been linked to the quality, safety, and cost of patient care. To address these critical issues, The Ohio State University partnered with the National Academy of Medicine’s Action Collaborative on Clinical Well-being and Resilience to bring together hundreds of clinicians, leaders, influencers, students, and agents of change for the Third National Summit on Promoting Well-Being and Resilience in Healthcare Professionals. The summit took place September 28-30, 2022, in Columbus, Ohio.

Advantages of the cell block technique over the FNAC and correlation with histopathology of most prevalent breast lesions in the community at the tertiary care center
Authors: Puvvala Omkar Rama Krishna , Prakash Divya , Nuguri Vivek Kumar , Venkatapathappa Priyanka
Published: December 2022

Breast lumps are a common cause of concern in both young and older women throughout the world. Fine needle aspiration of breast lesions is an important and widely practiced method of providing a preoperative diagnosis in women presenting with a lump in the breast. Cell blocks that are made from the aspirates help in preserving the architecture, and the nuclear morphology and help in preserving the material for immunohistochemical studies. The present study aims to highlight the role of FNAC and cell block in the diagnosis of breast lesions.

This was a two-year prospective study of 72 patients presenting with palpable breast lesions referred for FNAC to the Department of Pathology JJMMC, Davangere from 1st July 2015 to 30th June 2017. After a detailed history, general physical & local examination, informed consent was taken and FNAC was performed under aseptic precautions. A part of the aspirate was fixed, then processed as cell blocks, and stained with H&E. Wherever lumpectomy or radical surgery was performed the histopathology was correlated with cytomorphological findings.

: The present study showed a diagnostic accuracy of 85.71% in the FNAC diagnosis. The sensitivity and specificity of FNAC in diagnosing breast lesions were found to be 82.60% and 87.23%. PPV and NPV were 76% and 91.11% respectively. When cell blocks were used the diagnostic accuracy increased to 88.57%. Diagnosis by using cell block showed a sensitivity of 79% specificity of 93.47%, PPV of 86.36%, and NPV of 89.58%.

: From the results of our study, it can be concluded that the accuracy of diagnosing breast lesions preoperatively can be increased when FNAC is combined with the cell blocks from the aspirates. The cell blocks also help to preserve the aspirated material for future reference and immunohistochemistry can also be applied for a more accurate diagnosis.
A dormant yet belligerent tumour, the sinonasal adenoid cystic carcinoma- A case report
Authors: Vasudevan Chenchulakshmi , Apoorva P , Sanikop Adarsh
Published: December 2022

Adenoid cystic carcinoma, also known as cribriform tumour or Cylindroma owing to the cellular arrangement or type of tissue that it originates from, is rare and shows perineural invasiveness as a pathognomic feature making treatment challenging. The tumour is known to arise in the salivary glands and seldom seen in the nasal cavity or paranasal sinuses. We here present a rare case of ACC occurring beyond its usual premise.

A male patient aged 32 presented with unilateral nasal obstruction and epistaxis and on examination a growth in the right nasal cavity was noted to peculiarly arise from beneath the mucosa of the nasal floor, extending posteriorly up to the choana, not involving the turbinates or septum. DNE with biopsy was done and CECT PNS was done for further evaluation and the mass was diagnosed to be stage III sinonasal adenoid cystic carcinoma.

This tumour originates from minor salivary glands and its presentation in the nose and paranasal sinuses has been reported to be very sparse. This is perhaps a reason for it to be missed out in daily practice due to clinical features being similar to several inflammatory and neoplastic diseases of the nose and paranasal sinuses. Histopathological cribriform and tubular subtypes are less aggressive than solid form and that determine the prognosis. It is a disease of 6th and 7th decade, slow growing and locally invasive very unusual to find it in a young patient such as ours.

Though uncommon the ACC mustn’t go undiagnosed and must be differentiated from commoner nasal masses. Otorhinolaryngologists need to work in collaboration with pathologists and oncologists to accurately diagnose and treat this belligerent tumour in a multifaceted approach. Complete surgical excision with post-operative radiotherapy is the most accepted treatment plan
Florid vascular proliferation of colon: An incidental finding in intussuscepted bowel with underlying adenocarcinoma
Authors: Kiruthiga Kala Gnanasekaran , Kulkarni Anusha Prakash , Joshi Aparna , Pradhan Avinash
Published: December 2022

A 47-year-old man presented with intussusception of the colon and was found to have a large tubulo-villous adenoma with high grade dysplasia, transforming into adenocarcinoma. The bowel adjacent to the polyp showed florid vascualr proliferation, mimicking a vascular neoplasm. However, there were no signs of atypia or malignancy in the vascular lesion. We illustrate an example of chronic obstruction inducing hypoxia, leading to neo-angiogenesis, histologically masquerading as a vascular neoplasm.
A pediatric case of anaplastic pleomorphic xanthoastrocytoma (Grade 3)
Authors: Sharma Saket , Rana Neema
Published: December 2022

Pleomorphic xanthoastrocytoma (PXA) is a glial tumor which accounts for less than 1% of astrocytomas. PXA most commonly occurs in the temporal lobe in the outer cortex of brain and usually seen in young adults and children. As per 2020 WHO classification of CNS tumors, PXA with a mitotic activity ≥5 mitoses/10 HPF is defined as anaplastic pleomorphic xanthoastrocytoma (APXA), WHO grade 3. Here we present a rare case of Anaplastic Pleomorphic Xanthoastrocytoma developing in a female child of 11 years of age.

A 11 years old female child presented with symptoms of continuous headache, giddiness, fever and vomiting since last 15 days. Computed Tomography of her brain revealed a soft tissue density mass lesion in right temporal lobe involving the insular cortex and capsuloganglionic region. The radiological differential diagnosis was a neoplastic lesion, most likely glioma. The patient underwent surgery for removal of temporal lobe tumor and the resected tumor bits were sent for histopathological assessment. Microscopically, many multinucleated lipidized giant cells were seen having eccentrically pushed nuclei, conspicuous nucleoli and abundant eosinophilic granular cytoplasm. A second population of few spindled cells with less amount of cytoplasm was also noted in the intervening parenchyma. Immunohistochemical workup showed the tumor to be positive for GFAP, S-100, Synaptophysin, p53 and CD-68. The tumor was negative for CD34. Ki-67 index was 15-20%. A final diagnosis of Anaplastic Pleomorphic Xanthoastrocytoma (grade 3) was made.

APXA is a rare astrocytic tumor and has relatively more aggressive radiological and histomorphological features than pleomorphic xanthoastrocytomas and therefore it needs to be identified and treated separately.

Distal phalanx intraosseous epidermoid inclusioncyst: A rare thing!
Authors: Pathak Garima , Gulati Rashi Ahuja , Joshi Hem Kumar , Sabharwal Paramveer Singh
Published: December 2022

Pathological structures called epidermoid bone inclusion cysts are surrounded by a layer of stratified squamous epithelium that contains keratin debris. They go by the name epidermal bone cysts as well. Intraosseous epidermoid cysts are uncommon lesions that can develop as a result of trauma (puncture wound or pressure erosion). They typically affect the toes, phalanges, and head. The distal phalanx of the fingers is where phalangeal involvement most frequently occurs. Despite the fact that the cause of intraosseous epidermal inclusion cysts is still unknown, the majority of patients do recall a prior traumatic event, supporting the post-traumatic origin theory. Following digital trauma or surgery, it is hypothesised that surface epithelial cells are pushed into the underlying osseous compartment.

Following the initiating event, symptoms may start to appear months to years later. It is challenging to distinguish intraosseous epidermoid inclusion cysts on radiographs from other radiolucent lesions, necessitating tissue diagnosis.

We present a case of a 45-year-old man with right middle finger distal phalanx edoema for five months and a known history of minor blunt trauma. A well-defined expansile hypodense lytic lesion with eccentric phalanx erosion was discovered during radiological analysis. A creamy substance was found inside the lesion after surgery, and it was later determined by histology to be an epidermoid inclusion cyst.

Gross examination of the surgical specimen indicated a cystic lesion with significant necrotic regions and pale, creamy material. A burst intraosseous epidermoid inclusion cyst was discovered upon microscopic inspection and was effectively removed.

Published: December 2022

Polycystic kidney disease is a rare developmental anomaly inherited as Autosomal dominant or recessive. Autosomal recessive polycystic kidney disease (ARPKD) is an intractable cystic renal disease that results in chronic renal failure. It has a profound effect on growing fetus and result in serious implications if pregnancy is continued in the long run after being detected on sonography. Although prenatal imaging studies and clinical findings are suggestive of ARPKD it can be accurately diagnosed by histopathology if an autopsy is performed in cases of infant death. In this article we here in present the features of ARPKD diagnosed antenatally by USG in a 22 yr female, and was confirmed further by fetal autopsy.

On some aspects of the fight against mobbing: problems of rulemaking and judicial practice
Authors: Lushnikov Andrey M. , Karpov Alexandr A. , Smirnov Dmitry A.
Published: December 2022

The article is devoted to the analysis of the problem of combating mobbing. The article substantiates that mobbing is not just an interdisciplinary concept, but also quite thoroughly rooted in common sense. Second, the everyday understanding of mobbing is clearly manifested in the claims of employees against employers, which were analyzed in the article. It was concluded that a request for a legislative ban on mobbing and its delineation was already quite ripe in society. The authors proposed a definition of mobbing, which they propose to include in the Labor Code of the Russian Federation. Also, the authors analyzed the current capabilities of employees in the fight against vertical mobbing (bossing). In particular, attention was paid to the provision of Art. 195 of the Labor Code of the Russian Federation, which gives the right to the representative body of employees to demand that the head of the organization be brought to disciplinary responsibility up to dismissal. The grounds for dismissal, which can be applied to the manager in the event of a boss, are analyzed. It was concluded that without a legislative ban on mobbing, bringing the head of the organization to justice is quite difficult. Also, by-laws, which mention mobbing, in the field of education, were analyzed. It was concluded that the state and local governments are making certain efforts to combat mobbing, but these efforts are aimed at mobbing in relations between students. As for the fight against mobbing of teachers in relation to students and each other, the authors identified 3 grounds for dismissal, according to which, according to the current legislation and judicial practice, a teacher can be dismissed.

Representation of the literary protagonist’s figure and its authorial characterization in translation (exemplified by American prose)
Authors: Zhulidov Sergey B. , Zolotova Marina V. , Ivanov Sergey S.
Published: December 2022

Interrelation of literary and linguistic aspects in translating prosaic literary works - a contemporary American novel - into Russian is dealt with. Paramount attention is focused on the most significant literary aspect - the protagonist’s figure and its characterization formulated by the author of the original as well as her peculiarities recreated and represented in the translated text. The protagonist’s main features are defined concretely on the basis of the authorial description and characterization of her appearance, behavioral, psychological and some other personal individual traits represented in detail in the original, but, however, either deliberately distorted or erroneously translated. The methodology of research is based primarily on the comparative linguistic analysis of relevant excerpts taken from the original and its published translation. Special attention is paid to the results of the performed distortions followed by the authors’ detailed commentaries and, in most cases, their own suggested versions of contextual correspondences. A strictly systematized explicit classification consisting of four types of the translation invariant’s violation, defined and exposed by the authors, will, hopefully, help systematize them while teaching translation to philology students as well as caution translators of literary prose, both beginners and advanced ones, against making mistakes of this sort in their practical creative activities.

Published: December 2022

Cinereous Harrier Circus cinereus is a local species in Ecuador, occurring in agricultural grasslands and páramofrom north to central-south Andes. Little is known about its distribution in southern Ecuador. In this region, records are scarce and have not been adequately documented. We present the first video record of an adult female and a sighting of an adult male in the páramoof Quimsacocha National Recreation Area, Azuay province, southwest Ecuador. Our findings suggest that C. cinereus may be locally distributed further south of the currently known distribution and that it prefers open habitats, particularly cushion páramo, wetlands, and marshes in the high Andes and humid inter-Andean valleys.

Authors: Garcia-Rodríguez Luis Eduardo , Gonzalez-Guzman Luis Germán
Published: December 2022

El uso del agua suministrada por los acueductos y/o agua subterránea en la actividad de lavado de autos es una práctica general a nivel mundial. Las estaciones de lavado de vehículos convencionales son uno de los sectores de servicios que más consume agua en su proceso productivo. La mayoría de los establecimientos son convencionales y desconocen las ventajas que les traería recircular el agua residual. Se estima un volumen entre 250 y 500 litros de agua para realizar un lavado general de un automóvil y otros, este vertimiento genera un impacto negativo al medio ambiente debido a que estas aguas residuales terminan en cuerpos de aguas, ríos y quebradas. A partir del año 2017 en el servicentro Deprisa ubicado en Bucaramanga (Colombia), se instaló un sistema piloto de Ecolavado electrofloil para el tratamiento, aprovechamiento y recirculación del agua residual no doméstica y así eliminar el vertimiento al alcantarillado. Lo anterior permitió cumplir con el programa de uso eficiente y ahorro del agua estipulado en la ley de Colombia 373 de 1,997 y a su vez logró la certificación como negocio verde, emitido por la Corporación Autónoma Regional Para la Defensa de la Meseta de Bucaramanga (CDMB). El sistema piloto de recirculación instalado en el año 2017 logró reducir el agua de consumo un 80% y un impacto positivo en la reducción de las emisiones de dióxido de carbono, generando beneficios ambientales y económicos.
Empirical Modelling and Multi-Objective Optimisation of Laser Micro Machining on Magnesium Alloy AS21-SiC Metal Matrix Composite
Authors: Rao D Rognatha , Srinivas C
Published: December 2022

Micromachining techniques are now being used more frequently as a result of miniaturization. This technique has been supported by the requirement for material processing at an affordable cost and microatomic resolution in numerous sectors. Laser micromachining is a precise, non-contact method of machining that is used to create tiny, up to 500 m, components. The small elemental areas are the focus of laser ablation, which helps absorb a high amount of energy. In this micro-machining, metal removal rate and surface finish are represented by the deepness of the groove and the height of the recast layer. While machining, a layer called a recast layer forms on the work piece surface as a result of the tremendous heat generated, and this layer is damaging to the component's surface quality. For accurate applications, the recast layer must be as tiny as possible. As a result, the objective functions are the height of the recast layer and the deepness of the groove. Experiments designed by the DOE are used to generate empirical models. For each experimental run present in the matrix, the specified input parameter combination is set and the work piece is machined accordingly. The response surface methodology based on mathematical modeling and analysis of the machining properties of a pulsed Nd: YAG laser during micro-grooving operation on a work piece of Magnesium Silicon Alloy metal matrix composite is the focus of this research study. Initially, magnesium alloy AS21-SiC metal matrix composites are manufactured with Ultrasonic pro assisted stir casting. For the machined samples, the deepness of the groove and the height of recast layer will be measured by an optical measuring microscope. Consequently, the measured data is used by the GP to develop the mathematical models. In this work, an efficient GA-based genetic algorithm (NSGA-II) is applied to obtain the optimal parameters. As the chosen objectives are conflicting in nature, the problem is formulated as a multi-objective optimization problem.
Improvement of the algorithm for adaptive separation of the vibroseis signal from its harmonics in case of strong additive noise
Authors: Denisov M. S. , Zykov A. A.
Published: December 2022

An algorithm for separating a vibroseis signal from its harmonics implies preliminary prediction of harmonics with their subsequent adaptive subtraction from the correlogram. To obtain the adaptation filter estimates, a statistical criterion is used that minimizes the energy of the subtraction result. The amplitudes of the signals in a seismic trace decay due to geometrical spreading, which leads to statistical inhomogeneity in the objective formed. Therefore, an increase in the statistical reliability of estimation should be associated with an increase in signal amplitudes at large recording times. On the other hand, the source records always contain additive noise, and the signal-to-noise ratio decreases at longer times. In order to provide a compromise between the growth of signal amplitudes and maintaining a satisfactory signal-to-noise ratio in the operator adjusting gate, self-tuning weighting functions are included into the objective. A method for modifying the objective is proposed, which enables increased performance of the algorithm.
The Case of the Curious Comestible from Bengali into English: Rendering Sarcasm, Polysemy, Ambiguity, and Connotation by Direct Translation, Footnoting, Transliteration, and Addition
Authors: Sircar Sanjay
Published: December 2022

A translator's choices include directly translating source language words into the target language (with and without inverted commas), retaining these in transliteration, explaining them in footnotes, and inserting unmarked additional words (a few or many) as seems best. This essay focuses on a single word, a metaphor for reddening in anger, its literal referent most likely the word for a sweetmeat, the Bengali lāl-mohan, used sarcastically (so it seems) for the angry being to whom it is applied. This comes from Gaganendranath Tagore's classic humorous fantasy narrative Bhondaṛ Bahadur (1926), translated in Fantasy Fictions from the Bengal Renaissance (OUP, 2018). This word lāl-mohan has several referents, multiple etymologies, and  pairs of positive/negative connotations. A sense of all these is automatically part of the linguistic capital of the Bengali speaker, and not that of Anglophone readers, pan-South Asian or other.  Hence I attempt to justify my inclusion of what seemed to be the most important shades of meaning, and how I attempted this, and why I left out the others.
The online mock OSCE - a mixed-methods analysis of its benefits and overall student experience
Authors: Coe Calvin , Bryant Pauline
Published: December 2022

Background The social distancing requirements of the COVID-19 pandemic have resulted in an inability to deliver traditional, face-to-face Mock OSCEs; a means of clinical skill learning that has been shown to be beneficial to students. This study investigated the ability of an Online Mock OSCE to replace the in-person format and assessed whether similar benefits could be obtained by this method of delivery. Methods A student-run Online Mock OSCE was designed and rolled out to Year 2 undergraduate medical students; a questionnaire was then distributed to 43 students who consented to be involved in the research. Both quantitative and qualitative data were collected, with interpretation carried out via paired sample t-tests and supplementary thematic analysis. Results Comparison of pre-and-post-OSCE scores demonstrated a significant decrease in anxiety both towards summative OSCEs with similar stations and with different stations. Student confidence levels and self-reported retention of clinical skills showed statistically significant increases as a result of the Online Mock OSCE. Students had a strongly positive opinion of the process; analysis of written responses identified the provision of useful feedback on clinical skills, allowance of recognition of knowledge gaps, and enablement of increased familiarity with the assessment process as common justifications for this. Conclusions The Online Mock OSCE represents an excellent alternative to face-to-face delivery; it is well-received by students and offers a number of benefits, including decreased anxiety levels, increased confidence and improved self-reported retention of clinical skills, alongside logistical advantages of the online process. This study gives evidence for its continuing adaptation and inclusion within the medical curriculum even as in-person practice becomes feasible once more, such are the extensive assets it offers, and the potential for the method to be utilised within blended learning.

Authors: Balbuena Palacios Patricia
Published: December 2022

En el Perú, la pandemia del COVID-19 ha generado impactos en diversas dimensiones del desarrollo humano y del país. Si bien es cierto los niños y niñas no se han visto afectados en cuanto a la mortalidad, se evidencia un impacto negativo a corto y largo plazo sobre su desarrollo. En ese sentido, en el Perú la atención oportuna y de calidad a través del acceso al paquete integrado de servicios del Ministerio de Salud se vio severamente afectada, reduciendo su cobertura y generando escenarios de riesgo para el desarrollo físico, emocional y mental de los niños y niñas en el futuro. Ante este contexto, el Estado impulsó intervenciones temporales a través del Decreto de Urgencia 095-2020, entre ellas intervenciones dirigidas al desarrollo infantil temprano a cargo del Programa Nacional de Apoyo Directo a los más pobres “JUNTOS”. Este artículo tiene como objetivo examinar la implementación de dichas intervenciones por parte de “JUNTOS”, analizar los desafíos y resultados alcanzados, así como proponer hipótesis de trabajo para la investigación. Se propone explicar el éxito de la implementación a través de: i) la innovación ante los desafíos de implementación; ii) la relevancia de la coordinación intersectorial; y, iii) mejorar la calidad de lo servicios públicos a través de mecanismos universales de afiliación y acompañamiento a las familias.
Meeting the new challenges in the teaching of Western civilisation for EFL students
Authors: Rahmani Mokhtaria
Published: December 2022

Globalization has affected every aspect of life, particularly higher education. New values and aspirations came to shape learners’ attitudes towards education, exemplified by slender engagement in classes. Algerian EFL students are a good case in point. This urged teachers to make strenuous efforts to create convenient learning environments. Regarding the course of Western civilization, they had to equip themselves with new skills. This paper aims to explore, through the specific experience of the author, the nature of the adjustments made, pending both approaches and educational strategies. To conduct this investigation, the researcher used both a self-assessment and a student questionnaire destined for first-year students. The findings indicate the possibility of creating student-centered classes through the use of different teaching techniques such as outline composition, text analysis, discussion sequences, and summary writing. The paper demonstrates the necessity of constant updating of one’s teaching approaches and strategies.
Keywords:   Globalization; higher education; new skills; student-centered classes; Western civilization.

Hoy día los sistemas de generación renovables no convencionales a pequeña escala empiezan a tomar fuerza dentro de los sistemas eléctricos de potencia. La generación para autoconsumo puede beneficiar las pequeñas y medianas empresas a fin de volverlas más competitivas y atractivas hacia los clientes. Sistemas eólicos en pequeña escala, así como las instalaciones de sistemas solares son un ejemplo de cómo se ha masificado la tecnología, de manera que contar con un procedimiento explícito, simple y confiable para la implementación de sistemas renovables sería de gran utilidad. Este artículo presenta un procedimiento paso a paso a cerca de la implementación de sistemas fotovoltaicos en pequeñas industrias donde propone un diseño de una instalación incluyendo un análisis económico. Se toman en cuenta los sistemas de almacenamiento de energía. Los beneficios económicos y ambientales son cuantiosos, donde se demuestra una alta viabilidad de implementación de este tipo de aplicaciones en pequeñas industrias. Se logró concluir que la implementación de un sistema solar fotovoltaico en una pequeña empresa permite reducciones de costos de electricidad mayores al 90% con una pronta recuperación de la inversión.

La Agencia Internacional de la Energía en 2017 estimó que el 40% de la reducción de emisiones de gases contaminantes necesarias para que en 2050 se limite a dos grados el incremento de temperatura global, podría lograrse a partir de las medidas de eficiencia energética. En esta investigación se evaluó por medio de software el consumo de energía eléctrica anual del edificio N°1 de la UTP, se comparó el resultado con la facturación más reciente disponible y se propuso medidas de eficiencia energética, cuyos beneficios económicos y ambientales fueron también estudiados. Entre las propuestas planteadas se encuentran la instalación de lámparas LED, generación fotovoltaica, adaptaciones al sistema de acondicionamiento de aire, ventanas eficientes y ventilación del ático de la cubierta del edificio N°1 junto a la instalación de barreras radiantes. Los resultados obtenidos evidencian un consumo de 2 497 912 kWh/año, los cuales se verían reducidos en un 38.81%, representando un ahorro hasta de B/. 218 426.14 anuales y una disminución del 57.27% de emisiones de CO2.

Este proyecto simuló escenarios de confinamiento que buscan analizar diferentes formas de la sección transversal del plasma y de esta manera prever el parámetro beta óptimo en un tokamak esférico de baja razón de aspecto como lo es MEDUSA-CR. Además, se busca diseñar sistemas para operación y diagnóstico en este dispositivo. Finalmente, en este proyecto proponemos un experimento único como prueba de principio utilizando antenas RF para inducir ondas de Alfvén en un Tokamak esférico. Las simulaciones de las interacciones del plasma con las ondas electromagnéticas RF y ECRH permiten explorar en este dispositivo escenarios de calentamiento optimizado que también son del interés de la comunidad científica debido a que la alta temperatura es un requisito indispensable para procesos de fusión.

Cosmopolites sordidus est une contrainte majeure à la production de bananes (Musa spp.). Le champignon entomopathogène Metarhizium anisopliae, Ascomycota : Hypocreales, se présente comme une alternative de lutte contre les charançons. Nos enquêtes ont été menées pour évaluer l'efficacité de différentes luttes antiparasitaires dans les jachères et les bananeraies établies. Dans les jachères, le piège à phéromone inoculé avec Metarhizium et le piège à phéromone avec ramassage de charançons ont été comparés pour leur efficacité à réduire l'infestation larvaire de charançons. Dans le champ de bananes établi, le piège à pseudo-tronc inoculé avec Metarhizium a été comparé à l'application chimique, et la combinaison du piège à pseudo-tronc inoculé avec Metarhizium et l'application chimique. L'efficacité des traitements a été mesurée par les paramètres de Vilardebo : le coefficient d'infestation et le taux d'infestation. Les résultats ont montré que le traitement utilisant M. anisopliae s'est avéré le plus efficace, réduisant l'infestation larvaire. Dans les champs établis de bananier, insecticide chimique + traitement de M. ansisopliae et application mensuelle de piège à pseudotronc inoculé, ont réduit les paramètres d'infestation de plus de 50 %. Avant la replantation en jachère, une combinaison de phéromone + M. anisopliae avait diminué les niveaux d'infestation larvaire de 60 %. Les pièges inoculés avec le champignon entomopathogène Metarhizium sont apparus comme une méthode innovante et durable pour lutter contre le charançon du bananier Cosmopolites sordidus dans les champs de bananier et de plantain.
