L’insegnamento di bioetica nei Diplomi Universitari della sanità
Authors: Spagnolo Antonio G. , Sgreccia Elio
Published: December 2020

Lo spostamento nell’ambito universitario del luogo di formazione di molte figure professionali dell’area sanitaria, mediante l’istituzione di specifici corsi di Diploma Universitario (DU), ha richiesto anche un livello universitario di formazione bioetica. Gli obiettivi, contenuti nelle tabelle ministeriali, sono quelli di permettere agli allievi di acquisire durante il corso la capacità di valutare i propri comportamenti, di conoscere i principi bioetici generali e quelli specifici che costituiscono le basi del consenso informato e delle valutazioni di pertinenza dei Comitati di bioetica, di approfondire le tematiche etico-deontologiche nella cura e nell’assistenza delle persone.

L’articolo, che costituisce uno dei capitoli di un “manuale di bioetica” specificamente rivolto agli allievi e ai docenti dei DU, intende fare il punto sul problema dell’insegnamento della bioetica, considerando alcuni aspetti. Innanzitutto, la collocazione più opportuna della disciplina nell’ambito dei corsi integrati. Gli autori, presentando l’esperienza della Facoltà di Medicina chirurgia dell’Università Cattolica del S. Cuore e tenendo conto anche delle indicazioni in materia del Comitato Nazionale per la Bioetica, propongono l’inserimento della bioetica sin dal primo anno di corso e non solo all’ultimo come previsto dalle tabelle ministeriali.

Circa gli obiettivi che gli allievi dovrebbero raggiungere, viene sottolineata la necessità di far sviluppare una maggiore consapevolezza e un’adeguata capacità di analisi razionale dei dilemmi morali nella professione, preparando lo studente ad accettare le responsabilità derivanti dal suo ruolo di operatore sanitario sia come singolo che come membro di una équipe.

Metodologicamente, viene proposto di programmare un modulo di insegnamento in parte integrato ad altre materie per far cogliere l’aspetto pratico della bioetica, in parte distinto per comprende il nucleo teoretico che ci deve essere dietro ad ogni decisione etica.

Infine, viene proposta la formazione di una specifica figura di docente di bioetica, per la quale andrebbe previsto e strutturato un corrispondente itinerario formativo risultante il più possibile da una integrazione di competenze disciplinari diverse.
Bioetica clinica - Adolescenza e comportamenti alimentari: orientamenti etici e strategie educative
Authors: Marinozzi Lorenza
Published: December 2020

In questo articolo l’Autrice, attraverso un’accurata analisi nosografica dei disturbi legati all’alimentazione e attraverso la descrizione di due casi clinici, afferma che sia l’anoressia nervosa, sia la bulimia nervosa, pur presentandosi con sintomi diversi, sono manifestazioni di un’unica malattia. Questo disturbo colpisce soprattutto l’età dell’adolescenza ed ha radici sociali e culturali. L’attuale epidemia non è altro che il riflesso dell’epoca in cui viviamo con tutte le sue ambiguità e contraddizioni, con tutti i suoi modelli irraggiungibili e irreali.

Un capitolo a parte è dedicato alle considerazioni etiche al fine di mettere in luce le proposte preventive oltre che curative. A questo proposito risulta molto importante la figura del genitore, il cui ruolo è quello di “navigatore”, di colui che indica la strada giusta senza però imporla. Le coordinate da seguire sono l’amore, l’ascolto, l’attenzione, unite al recupero di determinati valori quali “l’impegno lavorativo”, “il coraggio di affrontare gli ostacoli”, “la pazienza di aspettare”.

Published: December 2020

Изучается матричная задача Римана-Гильберта для модифицированного уравнения Ландау-Лифшица c ненулевыми граничными условиями на бесконечности. В отличие от случая нулевых граничных условий, при прямом рассеянии возникают многозначные функции. Для постановки задачи Римана-Гильберта введено аффинное преобразование, переводящее риманову поверхность в комплексную плоскость. В прямой задаче рассеяния подробно исследованы свойства аналитичности, симметрии, асимптотическое поведение функций Йоста и матрицы рассеяния. Кроме того, найдены дискретный спектр, условия на вычеты, следовые формулы и тета-условия в двух случаях: при наличии в спектре простых полюсов и полюсов второго порядка. С помощью задачи Римана-Гильберта, сформулированной в терминах функций Йоста и коэффициентов рассеяния, решены обратные задачи. В целях дальнейшего изучения структуры солитонных волн рассмотрено динамическое поведение солитонных решений модифицированного уравнения Ландау-Лифшица с безотражательным потенциалом. Проведен графический анализ некоторых значимых характеристик этих солитонных решений. На основании аналитических решений обсуждается влияние каждого из параметров на динамику солитонных и бризерных волн, а также предлагается метод управления такими нелинейными явлениями.
Взаимный переход андреевских и майорановских локализованных
состояний в сверхпроводящей щели
Authors: Chuburin Yurii Pavlovich , Tinyukova Tat'yana Sergeevna
Published: December 2020

С помощью гамильтониана Боголюбова-де Жена аналитически исследуются две модели со сверхпроводящим порядком: $p$-волновая модель с примесным потенциалом и $s$-волновая модель нанопроволоки с индуцированной благодаря эффекту близости сверхпроводимостью и с примесным потенциалом в присутствии поля Зеемана и спин-орбитального взаимодействия. С помощью уравнения Дайсона изучаются условия возникновения андреевских локализованных состояний с энергиями вблизи границ сверхпроводящей щели и возможность их перехода в майораноподобные локализованные состояния. Доказано, что для обеих моделей в топологической фазе (в $p$-волновом случае и в тривиальной фазе) могут существовать устойчивые андреевские локализованные состояния с энергиями вблизи границ щели, но если в $p$-волновой модели их возникновение обусловлено появлением (немагнитной) примеси, то в $s$-волновой модели они возникают лишь при локальном возмущении поля Зеемана. Для обеих моделей переход андреевских локализованных состояний в майораноподобные состояния (и обратно) в топологической фазе невозможен, что объясняется топологической защищенностью майораноподобных локализованных состояний в топологической фазе.

Authors: Rasappan Senthilkumar , Devi K. Indira
Published: December 2020

This paper proposes the application of matrix converter in supplying power from vehicle to grid (V2G) and grid to vehicle. Single phase matrix converter with four switches acting as DC to DC converter in bi-directional operation is proposed. The performance of DC to DC converter adopted for V2G operation is also applied with matrix converter operation. The DC bus is supported by hybrid power system. It comprises of solar and wind energy. Perturb and observe controller algorithm is adopted for power tracking of hybrid system. The charging systems of the batteries are connected by the service provider while the vehicles are parked and the battery also supports the service provider when any interruption occurs, thus a bi-directional power transfer is achieved. The results obtained here illustrate the better power transfer from the hybrid system to grid and grid to vehicles battery.

Authors: Mohan Manikandan , Udaiyakumar K.C.
Published: December 2020

Voluminous cram has been carried out in this project which is intended to improve the conjugate heat-transfer performance of a heat-exchanger. In this study, CFD method is effectively used to predict the effect of Protruded Fins in heat exchanger, which protrudes inside the tube in addition to the shell side. CFD analysis on Protruded Finned Heat Exchanger (PFHE) is carried out with three different fin configurations like rectangular, triangular and parabolic fins. The baseline model of counter flow shell-tube heat-exchanger is considered with standard dimensions and analyzed initially without fins. Later the numbers of fins are increased to optimize the fin position and counts. The shape of the fins is then modified to find an optimized model with a higher heat-transfer coefficient. Hence, the present conjugate heat-transfer and flow analysis focus on optimizing the number of fins for a heat-exchanger with counter flow along with the shape optimization of fins. The computational values are measured with the net heat exchange between the cold and hot-fluids in terms of temperature difference. Also, the area averaged surface heat transfer co-efficient (h) of the heat exchanger with different fin configurations are plotted and compared.

Published: December 2020

Self-weight and durability analysis of non-airconditioned sleeper bus has been carried in present work. Automotive industry standards (052 and 119) are used to freeze bus dimensions. Generative surface design is used in preparation to compute model. The bus superstructure behaviour is simulated for load on cant and waist rails for self-weight analysis. Bump analysis is carried out considering total failure of suspension system. Behaviour of bus during bump is simulated for two situations i.e. bump focre applied to front left wheel suspension location and all other suspension locations are fixed and force applied to front two wheel suspension locations and rear two wheel suspension locations are fixed. Behaviour of bus under torsional load for two cases viz first, force is applied to left of front suspension location in upward direction and other on to right suspension location in downward direction while the rear wheel suspension points are fixed and in second case, force is applied to left of front suspension in upward direction while the second one is applied to right in rear suspension location. Braking and double lane change load conditions are simulated with a braking efficiency of 80% and a lateral load of magnitude 0.4g is evaluated. Durability of the bus based on outcomes from braking, bump, torsional and double-lane change road-load situations is evaluated. The stress and deflection magnitudes are in good agreement with the results available in literature.

Authors: Dinesh S. , Rajaguru K. , Saravanan K. , Yokeswaran R. , Vijayan V.
Published: December 2020

Automotive shafts require maximum strength with regard to axial, bending and torsional loading to transmit power to various parts of a vehicle. Hence, it is very critical to analyse the manufacturing process and its governing parameters to exercise control over the surface properties of the shaft as it needs to be precisely manufactured in terms of dimensions and the surface roughness. The effect of three input parameters over two responses are considered as two major criteria's for production of shaft. The input parameters are speed, feed and depth of cut whereas the responses are material removal rate and surface roughness. Central Composite design was used and experimental results were analysed with Response Surface Methodology. ANOVA analysis was carried out to identify the most contributing parameter for MRR and SR. Grey Relational Analysis was adopted to identify the most feasible combination of machining parameters for turning process. The optimized parameter is identified as speed of 1000 rpm, 0.15 mm of feed and 0.35 mm of depth of cut using Grey Relational Analysis.

Authors: Dharamendara M. , Jegadeeswaran N.
Published: December 2020

Degradation by high temperature oxidation is one important failure mode of the components made from Ti alloys, used in hot sections of gas turbines. One possible way to overcome this problem is to use coatings, which can withstand oxidation environment at elevated temperatures. The present research work explores the possibility of use of HVOF sprayed cermet coatings on the materials used in gas turbine systems followed by laser heat treated on the coatings. Oxide alloy powder will be sprayed on titanium alloy (Ti-15) used in turbine related applications. Oxidation studies were conducted in an air at 700ï‚°C for 50 cycles by thermogravimetric method. It is followed by the investigation of their cyclic oxidation of the coating behaviour before and after laser heat treated is compared with un-coated substrate alloys by thermo gravimetric method. The reaction products of oxidized samples will be identified and gone through structural investigation made by means of X-ray diffractometer (XRD), Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Analysis (EDAX) techniques.

Published: December 2020

Accompanying the development of mechanical industry, the demand for alloy materials having high hardness, toughness and impact resistance are increasing. Nevertheless, such materials are difficult to be machined by traditional machining method. Hence CNC machines are used to machine such materials, which are capable of producing fine, precise, corrosion and wear resistance surfaces. The problem of arriving at optimal levels of operating parameters has attracted the attention of the researchers and practicing engineers, for a very long time. Thus, this paper demonstrates the optimization of the process parameter of machining Inconel 718 super alloy material via., the Taguchi methodbased grey analysis. The modified algorithm adopted here was successfully used for both detraining the optimum settings of machine parameters and for combining multiple quality characteristics into one integrated numerical value called grey relational grade. An attempt has been made to identify the influence of various cutting parameters i.e., speed, feed rate and depth of cut on physical part characteristics i.e., metal removal rate and surface roughness. The predictions of optimal process parameter with respect to the response are the end results of the paper.

Authors: Manjunath C. , Somesha G.H. , Majumdar Sekhar
Published: December 2020

The complex fluid dynamics of different flow situations at low Reynolds number for natural flying objects like birds and insects, needs to be clearly understood for arriving at an optimum design for sizes ranging from the small man-made ones to very large size high speed commercial aircrafts or the fighter aircrafts. Airfoil performance at low Reynolds numbers impacts the performance of a wide range of systems. Computational Fluid Dynamics (CFD) tools have been around for a couple of decades now. With the superfast growth of computing power, speed and accuracy of these mathematical tools have improved to a considerable extent. However, any CFD simulation employing turbulence models needs to be validated against reliable and accurate measurement data obtained from wind tunnels. The present work focuses on 2D numerical simulation of turbulent flow past a symmetric NACA4412 aerofoil, using C- grid topology, for a Reynolds number of 1 million and 3 million. The computation uses the CFD code RANS3D, an implicit, pressure-based finite volume type Reynolds averaged Navier-stokes solver in generalized non-orthogonal curvilinear coordinates.

Systemic amyloidosis is a heterogeneous group of diseases associated with protein misfolding into insoluble beta-sheet rich structures that deposit extracellularly in different organs, eventually compromising their function. There are more than 30 different proteins, known to be amyloidogenic with “light chain” (AL)-amyloidosis being the most common type, followed by transthyretin (ATTR)-, and amyloid protein A (AA)-amyloidosis. Systemic amyloidosis is a rare disease with an incidence of around 10 patients in 1 million inhabitants. Recently several new therapeutic options have been developed for subgroups of amyloidosis patients, and the introduction of novel therapies for plasma cell myeloma has led to an increase in the therapeutic armamentarium for plasma cell disorders, including AL amyloidosis. Among them, proteasome inhibitors, immunomodulatory agents (-imids), and monoclonal antibodies have been successfully introduced into clinical practice. Still, high-quality data from randomised controlled trials regarding the benefit of these cost-intensive drugs in AL amyloidosis are widely lacking, and due to the rarity of the disease many physicians will not gain routine experience in the management of these frail patients. The diagnosis of AL amyloidosis relies on a close collaboration between clinicians, pathologists, imaging experts, and sometimes geneticists. Diagnosis and treatment options in this complex disorder should be discussed in dedicated multidisciplinary boards.
In January 2020, the first meeting of the Swiss Amyloidosis Network took place in Zurich, Switzerland. One aim of this meeting was to establish a consensus guideline regarding the diagnostic work-up and the treatment recommendations for systemic amyloidosis tailored to the Swiss health care system. Forty-five participants from different fields in medicine discussed many aspects of amyloidosis. These are the Swiss Amyloidosis Network recommendations which focus on diagnostic work-up and treatment of AL-amyloidosis.

This electronic document is a report on Image Stitching. Image stitching is the process of creating an image
panorama from a given set of images that have some common(overlapping) area in them. Previous researches
done on this topic show that there is still a lot of scope for improvement in this field as although we are able to
achieve good results but we haven’t really been able to achieve perfection. There are a lot of factors that are
to be blamed here. While Stitching Images, there could be many challenges such as images being corrupt by
noise and/or presence of parallax in the images. Image Stitching process is divided into 5 major steps: Image
Registration, Feature Detection, Feature Matching, Homography Estimation and Image Blending. In this
document we are going to discuss the current status of image processing techniques and what are the
challenges being faced.

Decentralized Banking System on Ethereum
Blockchain
Authors: Gautam
Published: December 2020

Banking is the backbone of the financial sector of our times. Financial sector is one of the main facilitators in
the progress of our society. The world we see today would not have been possible without the banking
system. But the banking system currently has a centre dependency. CORE (Centralized Online Real-Time
Exchange) banking has major disadvantages like single point of failure, power and authority for planning
and decision making rest with top management organized around a hierarchical structure, dictatorial &
inflexible. Decentralized/Distributed banking is the need of the hour as it gives anonymity, low/no interest
rates, no single point of failure, power to the masses. It is resilient, inherently democratic and efficient.
Crypto Banks are decentralized banking platforms that provide the usual services similar to centralized
banks, primarily lending services and credit scoring. But it essentially cuts out all of the middlemen that a
centralized bank uses. There is no centralization whatsoever. The employees needed in a centralized bank to
structure financial data and approve loans are replaced in a crypto banking ecosystem by smart contracts
and p2p, peer-to-peer, services. Since all issues can be solved online, most of the network will be online.
The bank is moulded in the form of a computer interface, whether on a desktop or a phone, and the currencies
dealt with are mostly cryptocurrencies. In this project, I have created a smart contract on Ethereum
blockchain that functions as a bank. It covers basic banking operations - creating new accounts,
adding/withdrawing money, giving interest to the account holders, showing balances. I used Solidity
programming language to write the smart contract and wrote a few tests in Javascript. To test the smart
contract, I used Remix IDE. The project gives an idea of how crypto banks work in a real-time environment.

The paper presents the results of theoretical analysis and mathematical processing of experimental studies of the insulation state of individual elements of the same type of sections of 0.4 kV electric networks in underground workings conducted at the mining and processing mines at heights of workings up to 1000 m above sea level. The studies were carried out according to a single method in order to identify the effect of highlands on the insulation state of individual elements of 0.4 kV networks. It is recommended to complete scraper winches, fans and other mechanisms of high-altitude mines with organosilicon-insulated engines or with front coatings filled with top coat varnishes similar to excavator engines. A similar situation is noted with the launcher. More than 50 % of all the equipment of high-altitude mines have an active insulation resistance of less than 20 mOhm. A higher asymmetry of the total and active insulation resistance of launchers is noted. It is recommended to use silica gel to reduce air humidity inside the shells of the launcher...
CALCULATING FILTRATION AIR FLOW IN THE BLOCK OF GASIFIED COAL BED

Published: December 2020

The mathematical model for calculating the filtration air flow in the block of gasified coal bed is substantiated. It is proved that the rate of filtration of the air flow in the block of gasified coal bed will depend on the gas permeability of coal and the difference between the squares of the air pressure on the lines of injection and production wells. It is shown that the filtration rate of the air flow in the block of gasified coal bed is one of the main physical parameters of the process of underground coal gasification. Obviously, the efficiency of underground coal gasification can be controlled by changing the rate of filtration of the air flow, by changing the gas permeability of the coal bed and the differential pressure of air on the lines of injection and production wells.

A mathematical model of the temperature regime of a coal bed during underground coal gasification in a filtration channel for new geotechnologies of Tula State University is developed. It is proposed to describe the unsteady temperature field of the coal seam with the one-dimensional heat conduction equation with the heat sink that depends on the temperature of the coal bed. The equation is solved for semi-infinite space. The results of computational experiments have shown that the temperature front from the fire face moves deep into the coal bed. Consequently, in the process of underground gasification, pre-heating of coal in the gasified block and thermal preparation take place. Quite quickly, after the formation of stable combustion of coal in the fire face, a stationary temperature profile is established.

Los menores de edad se encuentran en una situación delicada frente a Internet, ya que son vulnerables a múltiples riesgos a los que están expuestos constantemente. En esta investigación se realizó una encuesta de once preguntas cerradas a una muestra de 137 estudiantes de Instituto de Jerez de la Frontera con el objetivo de analizar la probabilidad que tienen estos menores a sufrir una victimización por ciberacoso, así como comprobar si esta depende de las conductas de riesgos y los factores de protección. Los resultados permiten concluir que los menores están expuesto a una gran variedad de conductas de riesgos, pero las que incrementan la probabilidad de la victimización por ciberacoso son las horas que pasan conectados a Internet, el número de redes sociales en las que tienen un perfil y los riesgos altos y bajos. Los factores de protección que hemos recogido también muestran un efecto en la victimización por ciberacoso, siendo los padres los que más aportan información sobre Internet.

The purpose of this study is to determine the development of MSMEs in Gorontalo Regency and to provide new innovations in the development of MSMEs based on Creative Economy (Ekraf) and Gig economy in Gorontalo Regency. This study uses a descriptive qualitative approach, which describes and describes facts according to the phenomenon of how development is seen from the strengths, weaknesses, threats and opportunities (SWOT analysis) with the aim of providing an Creative Economy-based MSME development strategy and the Gig economy in Gorontalo Regency. Data collection was carried out through observation, interviews and documentation about the strengths, weaknesses, opportunities, and threats of MSMEs against informants from three business fields, namely the Food Business Sector (dodol processed food), clothing (Sulaman Karawo) and handicrafts spread across three existing sub-districts in Gorontalo Regency. The results showed that the creative economy-based and gig economy-based MSMEs in Gorontalo Regency have not been fully implemented by MSME actors because they have limited capabilities and experience problems in their business development, this is due to several problems faced such as limited capital, raw materials and the use of simple production equipment, limited marketing media due to the absence of a MSME center, the types of products offered, quite a lot of transaction costs, less skilled labor, and product copyright registration problems for that from the results of the SWOT analysis of the diversification strategy at a more precise value to be applied, because it is considered more appropriate to the current conditions in Gorontalo Regency. In addition, the use of the gig economy is a part-time worker who is competent and innovative for MSMEs that are progressing and ready to compete.

La demanda de alimentos a nivel mundial se duplicará para el año 2050, para lo cual se deberá incrementar la productividad agrícola. Esta acción sugiere el uso excesivo de insumos agrícolas sintéticos, tales como los plaguicidas, con el objetivo de garantizar la producción y calidad de los alimentos. Los plaguicidas son sustancias o mezcla de sustancias que son utilizados de manera intensiva para plagas y enfermedades agrícolas; sin embargo, diversos aspectos se deben considerar para su uso extensivo. El presente trabajo muestra una revisión crítica y propositiva sobre los diferentes tipos de plaguicidas empleados en la agricultura nacional para la producción de granos y hortalizas. Además, se analiza de forma detallada la contribución de estos fungicidas a la contaminación del suelo, y las repercusiones a la salud humana. Por otra parte, se discute la legislación mexicana y la posición actual de nuestro país ante esta problemática, integrando recomendaciones y alternativas sostenibles para contribuir de forma positiva al control de plagas, mitigando los efectos al ambiente y a la salud generados por el uso de los plaguicidas empleados actualmente.
Recopilación de antecedentes de la Universidad Veracruzana Intercultural sobre artes regionales y sus amenazas en Selvas, Grandes Montañas, Totonacapan y Huasteca.
Authors: Martell León Jesús Alberto
Published: December 2020

El arte indígena es parte importante de cualquier cultura,  se requiere  de saberes milenarios  y destreza manual para construir o producir obras. Estas pueden ser individuales o colectivas, permanentes o efímeras. El arte indígena se expresa en un sinfín de actividades que manifiesta un acontecimiento importante en relación a todo el año o temporadas del año. Dicho acontecimiento es parte de un conjunto que forma una cultura. En el presente trabajo se pretende seleccionar, clasificar y analizar información  de  documentos  recepcionales  de la Universidad  Veracruzana  Intercultural como metodología de estudio, para determinar qué tipo de arte se presenta en la zona de Selvas, Grandes Montañas, Totonacapan y Huasteca, y de qué manera están siendo afectadas. Los tipos de arte reportado para la zona de Selvas fueron la alfarería, el teatro, el arte textil, materia prima y tintes para el arte textil, fandango, fotografía, música y danza. En la zona de Grandes Montañas municipio de Tequila se registraron música de rock y prehispánica, trabajo artesanal de lana, técnica de telar y fotografía. En el Totonacapan son las danzas relacionadas con la ritualidad y la cosmovisión.  Y  finalmente  en  la  Huasteca  se  encontraron  reportes  de  bordados,  música  de Huapango,  banda  de  viento,  alfarería,  cestería  y  cera.  Lo  anterior  nos  muestra  que  algunas actividades se asemejan de una zona a otra, que aún existe diversidad de actividades artísticas, pero lo más notable y alarmante es que las  costumbres  y tradiciones  artísticas  están en  riesgo por diferentes factores, por lo cual el presente trabajo puede ser la iniciativa para reincentivar el gusto y la práctica de las actividades propias de cada zona.

Los sistemas de rendimiento que proveen estimaciones de volumen maderable por clase diamétrica (predicción implícita) son una herramienta de alto valor para la planificación del manejo forestal, ya que, al revelar la estructura del rodal, permite definir los tratamientos silvícolas que se pueden aplicar y saber a qué edad y diámetro se encuentra la mayor concentración de volumen. Sin embargo, la Cooperativa Integradora Forestal de Zacualpan, Veracruz (CIFZA) ha establecido 3,000 ha con Pinus patula durante los  últimos 14  años,  y no  cuenta con  estudios  que permitan  estimar  productividad o  predecir  el crecimiento maderable para programar la cosecha. Considerando lo anterior, se desarrolló un sistema en base a distribuciones diamétricas. En su construcción se utilizó información dasométrica derivada de dos remediciones en 50 parcelas permanentes de muestreo de 400 m2; en una crono-secuencia de edades que van de manera compacta de los 3 a los 11 años pero que tienen parcelas aisladas de hasta 21 años.  El sistema implícito se desarrolló tomando como base la distribución Weibull de tres parámetros y sugiere que a los 15 años la distribución diamétrica más probable concentra el 45.17% del volumen de árboles mayores de 25 cm. Evidentemente en plantaciones forestales comerciales se requiere de prácticas silvícolas intensivas y bien programadas a fin de maximizar el potencial de crecimiento durante los primeros 20 años.

Los metales pesados afectan la cadena alimenticia por su bioacumulación; ello es debido a su alta persistencia en el entorno. El estudio del contenido de metales en los alimentos constituye un aspecto de importancia debido a que algunos de estos metales son necesarios para el desarrollo normal de los organismos, mientras que otros, aún en bajas concentraciones no pueden tolerarse debido a su toxicidad para los seres humanos. El objetivo del presente estudio es registrar la concentración de metales pesados en Orechromis niloticus (tilapia). En septiembre de 2017, se colectaron 85 especímenes, se congelaron in situ y se transportaron al laboratorio para su análisis. Las muestras se analizaron mediante espectrofotometría de absorción atómica. Los resultados indican la presencia de Pb en peces, en el músculo se registró una concentración por encima de los límites permisibles. La presencia de Cr, Cd y Mn en las branquias se registró en concentraciones relativamente altas (Golovanova, 2008). Por lo tanto, es importante monitorear estos elementos para garantizar la calidad del pescado que proviene de este río en el cauce del Balsas. Los peligros de los metales para los seres humanos a partir del consumo de alimentos contaminados, dependerá de los niveles relativos de metal y su especiación. En caso de toxicidad crónica, se conoce que el plomo causa efectos dañinos sobre los riñones; además del deterioro de la función renal, disfunción hepática y escasa capacidad reproductiva (Abou-Arab et al., 1996); igualmente se ha reportado que en humanos, la exposición al plomo produce reducción del coeﬁciente intelectual, diﬁcultades de aprendizaje, retardo del crecimiento, anomalías de comportamiento, diﬁcultades de audición y de las funciones cognitivas (Dahiya et al., 2005).
