Aim of the study: to discuss available information on vaccination of pregnant and breastfeeding women against COVID-19. Pregnant women with SARS-CoV-2 infection are at high risk of developing severe COVID-19 and adverse outcomes due to increased rates of preterm birth, caesarean section, and neonatal admissions to the intensive care unit. Concomitant chronic diseases increase the number of maternal and fetal complications. Taking into account the passive immunization of the newborn by transplacental transfer of maternal protective antibodies into the fetus and newborn blood circulation and then through breast milk, the role of vaccination in pregnant and breastfeeding women increases. Conclusions: after an individual risk-benefit assessment, COVID-19 vaccine should be recommended for pregnant and breastfeeding women.

Authors: Kirdan Olena , Kirdan Oleksandr
Published: January 2022

The urgency of the study is due to the need to provide graduates of the Doctor of Philosophy educational and scientific programs with the mastery in methodology of pedagogical activities. The purpose of the article is to analyze the content, scope, components of the pedagogical component of educational and scientific programs aimed at training a Doctor of Philosophy. To achieve the purpose of the article we used these general scientific methods: analysis, synthesis, comparison, specification, generalization, content analysis to identify and characterize the peculiarities of developing the ability to teach students of the third (educational-scientific) level within the educational process of modern higher education institutions. The importance of the formation of teaching competence in the context of compliance with the provisions of legal documents related to the training of Doctors of Philosophy, descriptors of the National Qualifications Framework, criteria for assessing the quality of the educational program and professional standards is substantiated. It is emphasized that relevant competences, programme learning outcomes and educational components providing student’s development as a representative of academic staff are normative provisions of the programme under focus. It is emphasized that the formation of the pedagogical component of educational and scientific programs aimed at training a Doctor of Philosophy depends on the policy of an institution of higher education, which determines the scope of pedagogical (teaching) practice, sets disciplines prerequisites. Some possibilities of non-formal education for the development of the future PhD’s teaching competence are outlined. The conclusion about the role and importance of the pedagogical component of educational and scientific programs aimed at training a Doctor of Philosophy is made.

Ganar la calle: imágenes de la(s) resistencia(s) en Chile. A propósito de Hoy y no mañana (Josefina Morandé, 2018).
Authors: Lobo Carballo Olga
Published: January 2022

Desde los inicios de los 2000, una serie de documentales han ido retratanto un Chile en el que la indignación gana progresivamente terreno, poniendo en tela de juicio el discurso de la derrota impuesto por el golpe de Estado de 1973 y 17 años de dictadura. Este proceso culminaría en el estallido social de octubre de 2019, simbólicamente denominado despertar, cuya consecuencia más llamativa será la transformación de un espacio urbano, reapropiado y resignificado para cambiar el curso de la Historia. Chile despertó en la calle y desde la calle se consiguió lo que no pudieron los acuerdos políticos: poner fin al más despótico de los reductos del poder pinochetista, la constitución de 1980. Tras un breve recorrido por las “poéticas” de ocupación de la ciudad de Santiago, el artículo se centrará en el análisis de Hoy y no mañana (Josefina Morandé, 2018), uno de los documentales que, estudiado desde la perspectiva de la revuelta (y de género), nos permite profundizar en ese Santiago de Chile convertido en terreno de conquista de un pueblo, de nuevo, dueño de su destino.

Experiments Gone Wrong? Lived Experience of Filipino Teachers in Remote Science Education amid COVID-19 Crisis
Authors: Cahapay Michael B. , Labrador Mark Gil P.
Published: January 2022

The COVID-19 crisis moved teachers to engage in a sort of emergency instructional experiment to redesign how science could and should be taught. The lived experience of the teachers as implementers in the ground can be a source of practical insights in the continuous improvement of remote science education. Thus, the purpose of this phenomenology research is to analyze the lived experience of teachers in remote science education in the wake of continuing COVID-19 crisis. Through online interview procedures, eight purposively sampled secondary science teachers from public schools in Mindanao, Philippines were involved in this study. Using data analysis framework consistent with the descriptive approach in phenomenology, the responses of the participants were examined in stages. The results revealed four themes: (1) presenting difficult concepts in remote science teaching; (2) encountering challenges in the delivery of remote science teaching; (3) adjusting instructional practices in remote science teaching; and (4) drawing types of support to improve remote science teaching. These themes form the phenomenon of remote science education from the perspective of the teachers in the context of a crisis. Several practical recommendations to improve current remote science instruction are discussed at the end of this paper.

Eclipse mapping of Algol-type systems with oscillating δ Scuti type components
Authors: Lampens Patricia , Vermeylen Lore , De Cat Peter , Van Cauteren Paul
Published: January 2022

The oscillating Algol-type (oEA) stars are the former secondaries of evolved, semi-detached eclipsing binaries which are (still) undergoing mass transfer and form a newly detected class of pulsators close to the main sequence. Their unique feature consists of mass accretion onto the atmosphere of the pulsating star. Mass accretion affects the mass, radius, density as well as the star’s evolution. Such stars are therefore very attractive targets for asteroseismic studies. A new tool for mode identification of pulsating components in eclipsing binaries consists in using the event of primary eclipse as a spatial filter to resolve the pulsations across the stellar surface of the pulsator. During an eclipse, depending on the spatial structure of modes represented by the wave numbers (l,m), different shapes of the pulsation amplitude and phase variations can be observed. A comparison between the modelled and the observed amplitudes and phases then provides the correct mode identification. The method needs a geometrical model, the pulsation frequencies and the light curves as input. The geometrical model can be obtained from a simultaneous modelling of the light and radial velocity curves. The pulsation frequencies are obtained from subtracting a binary model from the original light curves followed by a frequency analysis of the residuals. We will identify and illustrate systems where observations with a fast CCD camera equipping the 3.6-m DOT telescope could deliver the data needed for the application of the eclipse mapping method.

Electrochemical Ozone Generation Using Compacted High Pressure High Temperature Boron Doped Diamond Microparticle Electrodes
Authors: Wood Georgia , Terrero Rodriguez Irina , Tully Josh , Chaudhuri Shayantan , Macpherson Julie
Published: January 2022

Electrochemical ozone production (EOP) from water is an attractive, green technology for disinfection. Boron doped diamond (BDD) electrodes, grown by chemical vapor deposition (CVD), have been widely adopted for EOP due to their wide anodic window in water and excellent chemical and electrochemical stability. High pressure high temperature (HPHT) synthesis, an alternative growth technique used predominantly for the high-volume synthesis of nitrogen doped diamond microparticles, has been seldom employed for the production of conductive BDD electrodes. In this letter, we demonstrate, for the first time, the use of BDD electrodes fabricated from HPHT conductive BDD microparticles for EOP. The BDD microparticles are first compacted to produce freestanding solid electrodes and then laser micromachined to produce a perforated electrode. The HPHT BDD electrodes are shown to exhibit high EOP, producing 2.23 ± 0.07 mg L-1 of ozone per ampere of current, at consistent levels for a continuous 20 hr period with no drop off in performance.
Hybrid Field Theory and Particle Simulation Model of Polyelectrolyte-Surfactant Coacervation
Authors: Madinya Jason , Sing Charles
Published: January 2022

Solutions of oppositely-charged polyelectrolytes and surfactants have been widely studied for a variety of applications; they play an important role in the formulation of personal care products, can be used as an effective strategy for drug encapsulation, and serve as analogues to biological systems such as biomolecular condensates. Surfactant molecules self-assemble into micellar macroions that are known to form complexes with oppositely-charged polyelectrolytes, and can undergo a bulk liquid-liquid phase separation known as complex coacervation. This process results in a `coacervate' phase that is rich in macroions, and a `supernatant' phase that is dilute in macroions. It is challenging to model this phase separation process, due to the disparate length scales and strong Coulombic interactions in these mixed macroion systems. In this work, we present a hybrid simulation and field theory model to describe polyelectrolytes/surfactants solutions, where the surfactant species has self-assembled into worm-like micelle structures. We use self-consistent field theory (SCFT) to model the polyelectrolytes in the solution which interact with the surfactant micelles. The surfactant micelle structures are determined by performing Monte Carlo (MC) simulations, which are used to determine applied external fields in the SCFT portion of the model. We use these calculations to determine the system free energy and map the phase diagrams for polyelectrolyte-surfactant coacervates, and subsequently consider the effect of a number of molecular parameters such as polyelectrolyte chain length, the volume of the interacting micelle surface-sites, and the electrostatic binding energy between the polyelectrolyte and micelle surface. Our model shows that local charge-charge correlations are critical for phase separation to occur. Additionally, we evaluate the statistics of micelle bridging by the polyelectrolyte, and the relationship between bridging and the densities of the macroions and salt ions. This hybrid SCFT/MC model can be generalized to study a variety of mixed macroion systems, and make predictions for phase behavior and molecular structure.

The Scottish Deathscape in South Asia: Madras and Ceylon
Authors: MacKenzie John M.
Published: January 2022

Imperial deaths were given the status of martyrdoms in the cause of what European contemporaries considered the advance of civilisation. In many cases burials stimulated the overblown architecture of commemoration discovered in many places in the Indian Ocean world. There could well have been at least 1,000 cemeteries and church graveyards in South Asia, as well as grandiloquent memorials in cathedrals and churches throughout the region. While there are many examples from the eighteenth century, these practices became particularly striking in the nineteenth, which was an era in which the obsession with data produced a plethora of directories of memorial inscriptions and related lives. Some of these were officially inspired while others were produced by undertakers and those fascinated by documentation. From these we learn about imperial lives, careers, localised origins, and social and familial contexts. However, both these directories and the memorials which they documented were much more than the sentimental appropriation of colonial space. They also reflected ethnic and religious diversity, becoming indicators of the ‘four nations’ as well as of the contrasting Christian denominations of the United Kingdom. This was perhaps particularly true of Scots, whose geographical, social and religious affiliations can be charted through many examples in the Madras Presidency of South India and of the colony of Ceylon. They help to demonstrate that a full understanding of ethnic diversities can be derived from the study of the ‘deathscape’ of the imperial world.

The aim of the present work is to estimate the accumulation of various elements related to the core sediment belong to the Krishna-Godavari marginal area with a nuclear analytical technique. Hence, a 4.12 m long marine sediment gravity core was collected from near to Nizampatnam Bay that related to Bay of Bengal and by using particle induced X-ray emission (PIXE) elemental concentrations have been determined. The concentrations of major elements like Fe, Ca, K, Ti, Mn and minor (trace) elements such as Sr, Co, V, Zn, Ni, Cu, Rb, Sc and Cr have been evaluated with the obtained PIXE spectra. These values are interpreted based on the monsoonal runoff coming from the rivers causing to play an important role for bring lot of sedimentary material of the coastal waters to the Bay of Bengal. Further results are interpreted to understand biological and anthropogenic activities, chemical reactions etc during Holocene and Pleistocene periods.
HEAVY METALS CONTAMINATION AND DISTRIBUTION IN SURFACE WATER AND SEDIMENT OF THE ABOABO STREAM, AHAFO REGION, GHANA
Authors: Brobbey Ebenezer Asante Boafo , Koomson Bennetta , Agyemang Frank Ofori
Published: January 2022

Activities of illegal small-scale miners promote continual introduction of wide pollutants into the Aboabo stream. Their toxicity poses health threats to the inhabitants of Krapoo village in the Ahafo Region, Ghana. The study assesses the impacts of illegal small-scale mining activities on the water quality of the stream. Levels of physico-chemical and microbiological parameters were determined using standard methods. Samples of sediment, water and plant were acid-digested with aqua-regia. Total Arsenic and Total Cadmium were analysed using Flame Atomic Absorption Spectrophotometer (FLAAS) whiles Total Mercury was analysed using Cold Vapour Atomic Absorption Spectrophotometer (CV-AAS). Turbidity, faecal coliforms and E-coli readings exceeded permissible limit of 5NTU and 0MPN/100ml respectively by Ghana’s Environmental Protection Agency (GS 1212) and World Health Organisation (WHO). Temperature, Electrical Conductivity and pH values were within the limit of <30oC, 1500μs/cm and 6.5-85 respectively at both seasons. Total suspended solids readings at the midstream were higher than the permissible limit. However, levels of total dissolved solutes and dissolved oxygen recorded, were below the limit. The sediments were also heavily polluted with Mercury, Arsenic and Cadmium. Alchornea cordifolia, Chromolaena odorata and Spigella anthelmia growing within the stream were taken to assess their efficiency in removing the heavy metals from the stream. It was observed that the plants species had bioaccumulation factor (BF) greater than 1 for cadmium. Alchornea cordifolia was the only plant with BF greater than 1 for mercury. The plants species are potential hyper accumulators for mercury and cadmium hence are suitable for phytoremediation.

Published: January 2022

This work seeks to assess the acid mine drainage (AMD) potential of stockpiled sulphidic gold bearing ore that was left untreated for a period of four (4) years. The mineralogical composition of the stockpiled sulphidic gold ore was determined using X-Ray Diffractometry (XRD) and Reflected Light Microscope. The AMD potential and kinetic studies on the ore sample were determined using Acid Base Accounting (ABA) and Humidity Cell (ASTMD 5744). The XRD and microscope analyses showed that the gold ore contain arsenopyrite and pyrite as the major sulphide minerals. The ABA confirmed that the gold sulphide ore could be a potential source of AMD with respect to AMD marginal of safety if the ore is left untreated for a very long period. Humidity Cell kinetic analysis showed a possibility of mobilizing Arsenic (As) into the geo-environment when there is a long period of oxidation of abandoned sulphide run-of-mine (ROM) ore.
DETERMINATION OF POROSITY-PERMEABILITY CORRELATION WITH PRESSURE AND DEPTH IN PART OF NIGER DELTA BASIN, NIGERIA
Authors: C. Ben Chukwu , -ari I. Tamunobereton , Opiriyabo Horsfall I.
Published: January 2022

Porosity indicates the potentiality or fluid storage capacity of a reservoir or rock. It is the first of the two essential attributes of a reservoir. Permeability is a parameter for the recovery of hydrocarbon from the reservoir, it is required for proper reservoir evaluation, as it aids in the estimation of how much fluid can produced from the reservoir. The aim of this study is to determine porosity-permeability correlation with pressure and depth in part of Niger Delta basin using well log data. A suite of geophysical well logs comprising of gamma ray, neutron, density, spontaneous potential and sonic logs from four oil wells were used in the study. Porosity values were estimated from well log data, while permeability and pressure values were determined using empirical relations with respect to specific depth in the wells. The results of this work show that three reservoirs (reservoir sands) were identified and correlated across the four wells, each reservoir sand unit spread across the wells and differs in thickness ranging from 8ft to 155ft, with some unit occurring at greater depth than their corresponding unit.The lithostratigraphic correlation section of the wells revealed a sand – shale sequence which is a characteristic of a typical Niger Delta formation. The average porosity, permeability, pressure and depth values for the four wells range from 0.001 to 0.309, 34.999mD to 306.360mD, 61926.863psi to 109928.054psi and 3000ft to 4450ft respectively. The analysis of the wells show that wells OTIG9 and OTIG11 have better reservoirs indicating high potentiality and productivity due to their more porous and permeable nature, reflecting well sorted coarse grained sandstone and linearity in the relationship between porosity, permeability, pressure and depth. The reservoir of well OTIG7 is the least porous but most permeable, thus is highly productive but less potential. The reservoir of OTIG2 has moderate potentiality and good productivity, hence is said to have average production capacity. The results of this work can be used as an evaluation tool for reservoir engineering activities, structural engineering, well stability analysis, blowout and lost circulation prevention.
DETERMINATION OF GEOMECHANICAL ROCK PROPERTY IN THE ESTIMATION OF SANDING IN FIELD “A” IN CENTRAL NIGER DELTA
Authors: I. Zi Chollom , -ari I. Tamunobereton , Opiriyabo Horsfall I.
Published: January 2022

Well logs data from four wells were analysed for determining the petrophysical and geomechanical properties of two reservoirs in the study area. The parameters derived from these properties were used to predict the likelihood of the occurrence of sanding in the reservoirs of interest. Five sand production methods were used in predicting sanding in the reservoirs of interest. The results obtained from these sand prediction methods all showed that the reservoirs were not likely to produce sanding during drilling exploration and production. Reservoir geomechanical study has a significant role that cannot be neglected in the development of various hydrocarbon exploitation procedures, such as in the exploration and production, drilling and field development phase. The role of geomechanical properties have great impact on the drill bit selection, optimization of well trajectory placement, casing design, wellbore stability analysis, safe mud weight window (SMWW) prediction and sand production. Sand production is a serious problem widely existing in oil/gas production. The problems resulting from sand influx include abrasion of downhole tubular/casing, subsurface safety valve and surface equipment, casing/tubing buckling, failure of casing or liners from removal of surrounding formation, compaction and erosion; and loss of production caused by sand bridging in tubing and/or flow lines.
SOFT-SEDIMENT DEFORMATION STRUCTURES AND GRANULOMETRIC PROPERTIES DISTRIBUTION IN AJALI SANDSTONE RIDGES, WESTERN AFIKPO BASIN, UTURU, NIGERIA
Authors: Oyanyan Raphael Oaikhena
Published: January 2022

Three Ajali sandstone ridges (L1, L2 and L3) at Uturu being quarried for construction sands were studied for soft-sediment deformation structures (SSDS) and granulometric properties distributions. SSDS that includes recumbents foresets, sands dykes, flame structures and fluid escape tubes were identified only in ridge L3. The geometry of the SSDS indicates sediment loading/density contrast, fluidization and liquefaction as the mechanisms for their formation but with liquefaction as the most dominant mechanism. Gran size analysis and granulometric curves properties calculations show that: Mean grain size ranged from fine (1.18 ɸ) to medium (2.57 ɸ); Sorting ranged from rarely poorly sorted (1.13ɸ) to well sorted (0.37ɸ) but with mean values in each ridge as moderate sorted; Skewness ranged from strongly fine skewed (1.0) to strongly coarse skewed (-1.57); and Kurtosis ranged from very platykurtic (0.27) to very leptokurtic (2.0) but with sands of ridge L3 mainly very platykurtic. Granulometric curves and bivariate plot of properties indicate fluvial deposition with rare marine influence. Results show that there is no significant variation in sediment properties and depositional environments across the three ridges. The localization of SSDS and non-proximity to any fault suggest that liquefaction, as the dominant mechanism for soft-sediment deformation, was not triggered by an earthquake. Possible mechanisms include rapid sediment loading, localised sudden subsidence induced by loading of localised oxidized compressible peats and coal; and increased in sediments’ water saturation via localised groundwater seepage. Fine grains, well sorting, fine to strongly skewed very platykurtic characteristics of sediments made it more susceptible to liquefaction.

This study uses the basic theory of critical discourse analysis combined between Theo van Leeuwen's model which focuses on micro aspects, namely discourse production using inclusion and exclusion strategies and Norman Fairclough's model on meso and macro analysis. The results of the analysis on the micro aspect with the use of exclusion and inclusion strategies in the discourse show the dominance of the inclusion of actors, namely the indigenous people of Kalimantan and environmental activists as victims of government policies in terms of relocating the capital city. The meso aspect analysis shows that the whole discourse production process was created and compiled by the BBC News team based on the results of field observations and interviews. The production team also showed more contra voices by including more counter arguments in the dialogue and narrative. The strategy for distributing discourse through the YouTube channel was chosen because the issue raised is an important issue and is currently being discussed nationally. The macro analysis shows the relationship that the BBC News coverage related to the issue of relocating the capital city to Kalimantan is about the majority of people in Kalimantan who are contradicting the issue of relocating the capital city.

A diminuição das taxas de natalidade, os avanços tecnológicos e científicos e a adoção de estilos de vida mais saudável são fatores que vem contribuído com o crescimento exponencial da população idosa. Pode-se dizer que o envelhecimento da população é um fenômeno mundial de números relevantes, inclusive, no Brasil. Os dados da Pesquisa Nacional por Amostra de Domicílios (PNAD-2005) revelaram que a população com 60 anos ou mais era de 18 milhões de cidadãos, ou seja, cerca de 10% da população, com a projeção de dobrar em termos absolutos até o ano de 2030. De acordo com a Organização Mundial da Saúde (OMS), o contingente de brasileiros idosos, por volta da metade deste século, poderá corresponder a um quinto da população brasileira. Todavia, as concepções da sociedade acerca da velhice e do envelhecimento ainda se baseiam em uma visão homogênea e estigmatizada, com respostas padronizadas para situações de características distintas. Cumpre-nos salientar que os idosos, os negros, os indígenas, as mulheres e os trabalhadores são exemplos de atores sociais historicamente marginalizados pela sociedade. A partir disto, podemos inferir que a sociedade vivencia um paradoxo dos tempos modernos, pois, ao mesmo tempo que se deseja viver muito, nega-se o fato de ser velho, ou de se parecer velho. Com isso, temos dois quadros. No primeiro, a cada dia, a ciência avança no ponto de vista teórico e clínico para conceber uma maior expectativa de vida aos mais velhos. No segundo, a sociedade demonstra rejeição às limitações funcionais, ao desgaste do corpo, aos vincos na face, à voz mais cadenciada, ao andar mais vagaroso e à fragilidade dos movimentos. Diante do exposto, versamos que a justificativa deste estudo se esteia na necessidade de ampliarmos os debates, não só nos meios acadêmicos, mas também na sociedade, no âmbito legislativo, no contexto familiar, a fim de ressignificando os conceitos e as noções acerca da velhice e do envelhecimento, estabelecendo novos contornos sobre os interesses e as realizações pessoais da pessoa idosa. O arcabouço teórico utilizado neste trabalho de pesquisa teve como respaldo os autores Simone Beauvoir (2018), Ecléa Bosi (2004), Norberto Bobbio (1997), Maria Cecília Minayo e Coimbra Jr. (2002), Anita Liberalessa Neri (1991/2011), Guita Debert (2012), dentre outros. Assim sendo, a metodologia ancorou-se em três desdobramentos que se articulam entre si: bibliográfico, documental e pesquisa de campo. Este último, realizado no Centro Municipal de Convivência em Tefé (AM). Ao contrário das representações incorporadas ao imaginário social, que associam a imagem da velhice a aspectos depreciativos, os idosos da pesquisa revelaram que envelhecer é um privilégio concedido a poucos e marcado por realizações pessoais.

Acute pancreatitis in childhood is not common and viral and bacterial infections, bile duct diseases, medications, systemic diseases, trauma, metabolic diseases, and hyperlipidemia are among the most common causes in them. Acute necrotizing pancreatitis is even rarer. The clinical presentation of Multisystem Inflammatory Syndrome in Children associated with COVID-19 (MIS-C) includes fever, severe illness, and the involvement of two or more organ systems, in combination with laboratory evidence of inflammation and with or without laboratory or epidemiologic evidence of SARS-CoV-2 infection. We present a case of a 15 years old boy with fatal acute necrotizing pancreatitis that fulfilled MIS-C definition based on RCPCH (Royal College of Pediatrics and Child Health) and CPSP (Canadian Pediatric Surveillance Program) criteria.

Malignant pericardial effusion is a usual and crucial exacerbation in malignancies. In some cases, pericardial effusion may be the first manifestation of the disease. Neoplastic pericarditis is extremely rare in thyroid cancer. Hereby, we describe the case of a 54-year-old man submitted to the hospital for chest pain and dyspnea. Clinical and radiological examinations were suggestive of pericardial effusion and mediastinal lymphadenopathy. The patient underwent pericardial drainage and surgical biopsy of a paratracheal lymph node. Pericardial biopsies were also taken. Histology study was compatible with metastatic papillary thyroid carcinoma with “signet-ring” cell morphology. Extended study of thyroid gland and function was performed and he was referred to oncologists for further treatment.

The Cauchy problem for a higher order modification of the nonlinear Schrödinger equation (MNLS) on the line is shown to be well-posed in Sobolev spaces with exponent \(s > \frac{1}{4}\). This result is achieved by demonstrating that the associated integral operator is a contraction on a Bourgain space that has been adapted to the particular linear symbol present in the equation. The contraction is proved by using microlocal analysis and a trilinear estimate that is shown via the \([k; Z]\)-multiplier norm method developed by Terence Tao.

A two-strain model of the transmission dynamics of herpes simplex virus (HSV) with treatment is formulated as a deterministic system of nonlinear ordinary differential equations. The model is then analyzed qualitatively, with numerical simulations provided to support the theoretical results. The basic reproduction number \(R_0\) is computed with \(R_0=\text{max}\lbrace R_1, R_2 \rbrace \) where \(R_1\) and \(R_2\) represent respectively the reproduction number for HSV1 and HSV2. We also compute the invasion reproductive numbers \(\tilde{R}_1\) for strain 1 when strain 2 is at endemic equilibrium and \(\tilde{R}_2\) for strain 2 when strain 1 is at endemic equilibrium. To determine the relative importance of model parameters to disease transmission, sensitivity analysis is carried out. The reproduction number is most sensitive respectively to the contact rates \(\beta_1\), \(\beta_2\) and the recruitment rate \(\pi\). Numerical simulations indicate the co-existence of the two strains, with HSV1, dominating but not driving out HSV2 whenever \(R_1 > R_2 > 1\) and vice versa.

La motivación y satisfacción con los estudios son dos variables fundamentales dentro del proceso de elección de una carrera, por lo que la presente investigación planteó como objetivo determinar si existe relación entre los tipos de motivación y la satisfacción con la profesión elegida, además de establecer diferencia entre los niveles de estudio y género; para ello se empleó un enfoque de investigación cuantitativo de alcance descriptivo-correlacional, diferencias de grupo y diseño no experimental-transversal. Los instrumentos que se utilizaron para recolectar datos fueron la Escala de Satisfacción con la Profesión Elegida, y el Cuestionario de Motivación para Estudiar Psicología (MOPI). La muestra calculada mediante fórmula fue de 213 estudiantes de la Carrera de Psicología Clínica de la Universidad Técnica de Machala. Los principales resultados evidencian que, no existe una relación significativa entre los tipos de motivación y los niveles de satisfacción que presentan los estudiantes, además, no hay diferencias estadísticamente significativas entre las motivaciones según el género ni los niveles de estudio, excepto en la motivación intrínseca de conocimiento que es mayor en los estudiantes de los primeros cuatro niveles, con respecto a los semestres superiores.
