The (In)Efficient Curriculum: An Overview of How Canadian Education Has Historically Failed to Welcome Black Refugee Students
Authors: Heringer Rebeca
Published: December 2021

For at least a century, educators have sought to define what education should look like, its purposes, content and approach, and how it could be delivered in the most efficient way. However, when looking at some of the most pre-eminent approaches in the history of curriculum studies, it is possible to observe how each of those “efficient” methods have not been able to welcome the uniqueness of Black refugee students. Despite claims of “diversity celebration”, when educators do not challenge and resist White structures and assumptions, even the most “efficient” curriculum falls short of being responsive to the Other, serving, rather, as another disguise to racism, which has long structured Canadian education. I argue that rather than an efficient ready-made set of rules, education must be conceptualized as an act of unconditional openness to the unknown Other, however uncomfortable and “inefficient” that may sound.
Dear Dr. D’Amour: Relational Psychoanalysis at the Heart of Teaching and Learning
Authors: House Darcy James W.
Published: December 2021

Dr. Lissa D’Amour brings together relational psychoanalysis and developmental theory to offer practitioners of education an opportunity to unify theories of learning into a cohesive “dialectic model of learning and of learning’s refusal” (D’Amour, 2020, p. 142), a unification sorely needed in mathematics education as educators in Alberta feud over ‘back-to-basics’. Dr. D’Amour’s (2020) book, entitled Relational Psychoanalysis at the Heart of Teaching and Learning: How and Why It Matters, attempts to kick-start conversations about the relationships present in classrooms and offers respite from, and an alternative perspective of, the educational behemoth I have become a part of, one that increasingly ignores us humans, the relationships we have and our affective attunement with all that is around us.

Authors: Rusydi Muhammad Ilhamdi , Farhan M. , Winata Yoan , Putri Dhiny Yurichy , Anwar Muhammad Dani , Berliana H. Daelita
Published: December 2021

Health professionals have to use Personal Protective Equipment (PPE) that could cover the entire body to prevent the transmission of the SARS-CoV-2 virus while examining patients. The current stethoscope is not compatible with the need of health professionals. Therefore, this project aims to create a digital stethoscope that can fulfill the requirement of health professionals to examine patients according to health service guidance in Covid-19 era. Three main objectives in designing the stethoscope are to meet the needs of health professionals, easy and convenient to use. The designed stethoscope has an amplifier circuit with 100 gain and a bandpass filter with 20 Hz and 700 Hz for low and high cut-off frequencies. It is also able to calculate the heart rate and displays it on the stethoscope screen. The stethoscope has a record function that lets the users replay sound as much as they need for the analysis. This digital stethoscope has function tests, performance tests and user satisfaction tests. Seven health professionals who are well-experienced in handling Covid-19 patients auscultate and provide an assessment of the three objectives design. The test results showed that this stethoscope satisfies the health professional’s requirements to examine the patient, grade 4.69 of 5. Health professionals also give a perfect rating for the objective of being easy to use. This stethoscope is the right choice for examining patients according to health service guidance in the Covid-19 era.

TECHNOLOGICAL UTOPIA AND ARTIFICIAL INTELLIGENCE: REPRESENTATION IN THE LITERATURE OF THE EARLY 21st CENTURY (BASED ON THE LIBRETTO OF THE ELECTRONIC OPERA “2032: THE LEGEND OF THE UNFULFILLED FUTURE” BY V. ARGONOV)
Authors:   KSPU named after V.P. Astafyev, Zagidulina T.A.
Published: December 2021

Problem statement. Scientific and technological progress associated with the ubiquitous spread of automation and development of the Internet entailed a transformation in the methods of production and perception of information, which outlined new ethical problems associated with technology and artificial intelligence, represented in fiction.Thus, the purpose of this article lies in identifying the elements of the phenomenon of techno-utopia in literature (based on the libretto of the electronic opera by V. Argonov “2032: The Legend of the Unfulfilled Future”), in determining the place of artificial intelligence in it, as well as in consider-ing options for resolving ethical issues related to this issue.Methodology (materials and methods). The paper demonstrates both traditional literary research methods (literary hermeneutics, analysis of mythopoetics) and philosophical methods (the author relies on the philosophy of technology, the philosophy of transhumanism).Research results. The results of the study are the identification of the genetic connection between techno-utopia and the Soviet utopian project, based, among other things, on Gnosticism, as well as identification of the central place of artificial intelligence in the artistic world of the emerging tech-nological utopia.Conclusions. Reading the text at the profane and religious-mystical levels provides a key to un-derstanding one of the vectors of development of socialist realist literature as utopian. It reveals how Soviet mythology is being transformed, for example, the myth of a large Stalinist family, the image of a leader on the basis of post-Soviet culture.As a result of the interdisciplinary complex analysis of the text, it can be concluded that there is a contradiction between the ideology of the new techno-utopia and the postulates of socialist realism.
Review of Open World Empire: Race, Erotics, and the Global Rise of Video Games by Christopher B. Patterson (New York University Press)
Authors: Sinnett Ian
Published: December 2021

In Open World Empire: Race, Erotics, and the Global Rise of Video Games, Christopher B. Patterson critically analyzes video games through the methodological framework of erotics. In doing so, he provides astute insights into the ways in which video games can work to challenge essentialized narratives and constructions of race while also fostering greater awareness and understanding of one’s own place within the larger geopolitical systems of capitalism and empire. Through understanding video gamers as not simply passive receptors of ideology, but rather as active participants in the gameplay experience, he contends that video games create pleasure and other forms of affective engagement through erotic play. Through this erotic play, Patterson argues that “games enact playful protests against the power, identity, and order of information technology” (7).

Objectives:

There is no consensus on the postoperative 30-day mortality, complication rates, and their risk factors post lower limb amputations (LLA) in the literature, especially in Saudi Arabia. To address this gap, we assessed these three parameters in our patients who underwent LLAs.

Methods:

We conducted a retrospective cross-sectional study in King Abdulaziz Medical City, Riyadh, Saudi Arabia, between 2015 and 2019. Using non-probability purposive sampling, we targeted 318 adults who underwent LLA at our hospital. The primary outcome variables were postoperative 30-day mortality and complications, such as stump pain, wound infections, hemorrhage, and acute kidney injury. In addition, we collected data on demographics, comorbidities, and clinical course from electronic medical records.

Results:

We assessed 318 patients (mean age = 65.7 [SD = 0.840] years), most of whom were male patients (68.6%) with endocrine and metabolic disorders (92.1%). Most amputees (87.1%) had peripheral vascular diseases as the main indication for LLA at an above-knee level (62.6%). The 30-day mortality and complication rates were 6.6% and 74%, respectively. Intermediate complications predominated (57%), with stump pain (17.3%) and phantom limb pain (15.4%) being the most common. Thirty-day mortality was significantly associated with some patient characteristics and comorbid kidneys and neurological disorders. The immediate, intermediate, and late complications were significantly related to smoking and several renal, vascular, and respiratory disorders.

Conclusion:

Calculating the 30-day mortality and complication rates after LLA and mapping the associated risk factors helped identify high-risk patients, deliver better treatment, lower medical costs, and establish protective measures.

Published: December 2021

В работе рассмотрена нелокальная задача с интегральным условием для нагруженного уравнения теплопроводности, где нагруженное слагаемое представляет собой производную второго порядка от неизвестной функции в начале координат. Доказано существование и единственность регулярного решения. С помощью функции Грина и тепловых потенциалов доказанао существование регулярного решения исследуемой задачи. Доказательство основано на редукции поставленной задачи к интегральному уравнению Вольтерра второго рода со слабой особенностью. Из разрешимости полученных интегральных уравнений Вольтерра следует существование единственного решения поставленной задачи.

In this paper, we consider a non-local problem with the integral condition for the loaded heat equation, where the loaded term is a derivative of the second order from an unknown function at the origin. The existence and uniqueness of a regular solution is proven. Using the Green’s functions and thermal potentials, the existence of a regular solution to this problem is proved. The proof is based on the reduction of the formulated problem to the second kind Volterra integral equation with a weak singularity. The solvability of the obtained Volterra integral equations implies the existence of a unique solution to the problem.

Vibronic coupling, the interaction between molecular vibrations and electronic states, is a pervasive effect that profoundly affects chemical processes. In the case of molecular magnetic materials, vibronic, or spin-phonon, coupling leads to magnetic relaxation, which equates to loss of magnetic memory and loss of phase coherence in molecular magnets and qubits, respectively. The study of vibronic coupling is challenging, and most experimental evidence is indirect. Here we employ far-infrared magnetospectroscopy to probe vibronic transitions in in [Yb(trensal)] (where H3trensal = 2,2,2-tris(salicylideneimino)trimethylamine). We find intense signals near electronic states, which we show arise due to an “envelope effect” in the vibronic coupling Hamiltonian, and we calculate the vibronic coupling fully ab initio to simulate the spectra. We subsequently show that vibronic coupling is strongest for vibrational modes that simultaneously distort the first coordination sphere and break the C3 symmetry of the molecule. With this knowledge, vibrational modes could be identified and engineered to shift their energy towards or away from particular electronic states to alter their impact. Hence, these findings provide new insights towards developing general guidelines for the control of vibronic coupling in molecules.
Mechanically axially chiral catenanes and noncanonical chiral rotaxanes
Authors: Maynard John , Gallagher Peter , Lozano David , Butler Patrick , Goldup Steve
Published: December 2021

Chirality, the property of objects that are distinct from their own mirror image, is important in many scientific areas but particularly chemistry, where the appearance of molecular chirality because of rigid arrangements of atoms in space famously influences a molecule’s biological properties. Less generally appreciated is that two molecular rings with chemically distinct faces combined like links in a chain results in a chiral structure even when the rings are achiral. To date, no enantiopure examples of such mechanically axially chiral catenanes has been reported. We re-examined the symmetry properties of the mechanically axially chiral motif and identified a straightforward route to such molecules from simple building blocks. We also identify that common representations of axially chiral catenanes obscure that a previously overlooked stereogenic unit arises when a ring is threaded onto a dumbbell-shaped molecule to generate a rotaxane. These insights allowed us to demonstrate the first stereoselective syntheses of an axially chiral catenane and a noncanonical axially chiral rotaxane motif. With methods to access these structures in hand, the process of exploring their properties and applications can now begin.

Australian Directors' Duties: What Does It Mean to Say They are Public Duties?
Authors: Kingsford-Smith Dimity
Published: December 2021

This article pursues the meaning and effect of what are (in Australia, at least )long-standing public duties of directors. It argues that there has been and continues to be, a slow evolution from an exclusively private character, to a hybrid public and private content in Australian directors’ duties. That duties may be both public and private, does not deny the truth of either of those characters. Instead, using the statutory duty of care in s 180(1) of the Corporations Act, this article analyses the juristic features and public elements that animate the duty and its enforcement sanctions. The cardinal legal and practical question of to whom the public directors’ duties are owed, both to no one in particular and to all the world, rather than only to the company, is also considered.
Rethinking Public Law in a Time of Democratic Decline
Authors: Palmer Geoffrey
Published: December 2021

The thirteen separate segments of this article are designed to explore the consequences for New Zealand public law of the global decline of democracy in many parts of the world, although not in New Zealand. The trend towards autocracy is evident in many countries and has been increasing. There was a time when democracy was thought to be inevitable, but that time has passed. Since New Zealand is a small and open society, democratic rot and decline could set in, as it has in other democracies. In order to combat these tendencies, it is necessary to think about the implications of these developments for teaching public law and for the need to bolster education in citizenship, so people can better understand the advantages of democracy, participate in it and feel a commitment to it. Many New Zealanders not born here may not understand the culture, may not have English as their first language and may be discouraged from engagement. New Zealand is increasingly diverse.The article explores the recent history of the United States and to a lesser extent, the United Kingdom, to discern the tendencies at work in those democracies. Returning to the fundamental elements of public law, it is suggested that the analysis begins with the nature and character of the state, followed by international law. Then it is argued it is necessary in the New Zealand context to examine the situation of Māori, Te Tiriti o Waitangi, the activities of the settler governments and the remaining consequences of colonisation. There appears at this time to be an opportunity to more significantly recognise indigenous Māori culture. From there, an examination of some important principles of political philosophy is provided. This leads to a summary of the main types of government that are available for any state. Then are set out the main political ideologies that often impel political actors. The changes in democratic practice that have resulted from the digital revolution are then examined with the effects upon political parties and how they have changed New Zealand. The manner in which public opinion can be manipulated and the need to become literate in politics and political practice is emphasised. The article concludes with a discussion of public law as an autonomous discipline and a final conclusion about what all this means for New Zealand. In the mind of the author, after a long career in public law and politics, these separate elements combine into a message about the need for democratic refurbishment and future vigilance in New Zealand.
One Boat, Two Captains: Implications of the 2020 Samoan Land and Titles Court Reforms for Customary Law and Human Rights
Authors: Land Craig
Published: December 2021

Samoa's 2020 Land and Titles Court reforms, which contributed to the Human Rights Protection Party losing support at the April 2021 elections after almost 40 years of government, have recentred attention on the tensions of legal pluralism in the South Pacific. Although Samoa maintains a system of English common law, 81 per cent of Samoan land falls under the traditional matai titles system, giving a central role to the customary Land and Titles Court (LTC). In December 2020, the Samoan parliament passed three Acts – the Constitution Amendment Act 2020, the Land and Titles Act 2020 and the Judicature Act 2020 – establishing the LTC in a parallel court hierarchy with equivalent status to the Samoan Supreme Court and Court of Appeal. This proposal has prompted debate between those favouring incorporation and promotion of Samoan custom over Western legal norms, and others who argue the amendments undermine human rights protections and the rule of law. This article evaluates the effects of these changes on the role and administration of custom in Samoa, contextualising them within broader socio-legal debates around customary legal systems. It first analyses the effect of the three Acts with regard to the bifurcation of the court system, procedural reforms in the LTC hierarchy and the introduction of a judicial guidance clause. This leads into a critical evaluation of these changes, highlighting impacts upon judicial coherence; constitutional human rights; consistency between customary and common law procedures; and resourcing constraints. The article concludes by providing broad options for future reform. It does not focus on issues which have received attention elsewhere, such as the amendments' potential impacts on judicial independence.
Commercial Common Sense in Contract Interpretation: Observations on the Court of Appeal in Technix v Fitzroy and The Malthouse v Rangatira
Authors: Marsich Ryan
Published: December 2021

The contemporary principles of contract interpretation require courts to have regard to a number of factors to determine the meaning of a contract, including the plain meaning of the express contractual language, the contract's context, and commercial common sense. These principles superseded the narrower plain meaning rule, which directed courts to interpret contracts in a manner largely consistent with the plain and ordinary meaning of their express words. Since their manifestation some 20 years ago, these principles have undergone change, development and elaboration to the extent that some commentators now claim the approach to contract interpretation more closely resembles the former plain meaning rule, with courts giving "primacy" to the words of the contract in order to deliver "commercial certainty". This article argues that while courts must give primacy to the express contractual language, that does not mean courts should maintain an unwavering loyalty to the plain meaning of those words, even if their meaning is clear. Courts that adopt this approach, referred to by some as the "conservative approach", risk obscuring the true meaning of a contract that can only be obtained through the careful balancing of a contract's internal and external factors, including commercial common sense. This article demonstrates the problem with the "conservative approach" through the analysis of two Court of Appeal decisions, and argues that courts should not overstate the circumstances in which departure from the plain meaning of a contract should occur.
Pushing the Boundaries: A Tentative Taxonomy of Money in New Zealand Private Law
Authors: Solinas Matteo
Published: December 2021

This article seeks to define the boundaries of money in the context of proprietary taxonomy in New Zealand. It suggests that the traditional legal concept of money exclusively based on state issued (fiat) currency is dated, as does not accommodate the near-universal use of bank money in commercial transactions, nor the recent technological changes introduced by virtual currencies. As long as something functions as a means of payment and the holder has the right to exchange it for legal tender, the divide between mutually agreed payment obligations into those made on the base of fiat currencies and those not, becomes artificial. In providing responses to similar commercial arrangements and parties' legitimate expectations, not only coins and banknotes, but also balances held by customers in banking institutions, foreign money, and digital currencies, should qualify as money for private law purposes.
Obligations in Contract, Tort and Equity: Reliance, Responsibility, and the Moral Dimension: Essay in honour of Sir John McGrath
Authors: Tipping Andrew
Published: December 2021

I publish this essay to honour the memory of Sir John McGrath. I sat with Sir John for a number of years, first in the Court of Appeal and then in the Supreme Court. Professional respect soon turned into friendship. While we did not always agree, I always respected his views. They were carefully considered and fully researched. John gave detailed consideration to the opinions of others but was very much his own man when it came to his ultimate conclusion. His innate caution in departing from the well-trodden path was a valuable contribution in a final appellate court. Stability is an important feature of any legal system. And John provided that quality, but not at the expense of innovation when that was clearly desirable and could be achieved in a principled way. John's passing, so soon after his retirement, was a great loss, not only to his wife and family, but also to his many friends and colleagues, both in the law and beyond.

Re-Membering and Naturing my Life and Work in a Fifth Province
Authors: McCarthy Imelda
Published: December 2021

This paper will outline my own systemic journey of engagements and movements in and away from a more natured inclusion in my life and work.   Looking back, I can see that from childhood my life was filled with sustainability practices in that I had parents who planted much of our food and never threw away anything that might be useful in the future. In my team, the Fifth Province Associates, one was a farmer’s daughter and grew up with a deep knowledge of our countryside and the other was an ecological and climate activist. How had I managed not to put all this together into a more coherent systemic roadmap before now? I thank Roger Duncan (2018) and many of my colleagues here in this issue for re-minding me of what I already knew and experienced, and how it could be recycled as it were for a possible more useful future (Simon & Salter, 2020; Palmer, 2014; Santin, 2020; Triantafillou et al., 2016; Edwards, 2020). They have facilitated me to re-member experiences around nature practices, the possibilities for love and colonisation in our practices, the co-creation of an indigenous Irish therapy practice and my experiences of a deep spiritual practice which I have seen over and over again to foster resilience and equanimity1 not only in my own life but also in the lives of clients and those in our Sangha. In the Irish language, the word for resilience, athléimneacht is interesting. Athléimneacht directly translated means jumping (across/in) a ford, an open space or a hollow between two objects. I resonate with this translation as it points to a liminal space so important in Celtic consciousness and of course a fifth province space. Maybe resilience or athléimneacht has been called forth as a need in all of us by the sudden advent, fear and stress of a world in panmorphic crisis (Simon, 2021).

Zemahşerî’nin Nahiv alanında kaleme aldığı el-Unmûzec adlı eseri hacim olarak küçük ama ilmî değeri yüksek olan bir çalışmadır. Şerhe muhtaç görülen bu esere birçok şerh yapılmıştır. el-Unmûzec şârihleri; tanım, istişhâd ve tenkitler gibi konularda önemli yorum ve tahliller yaparak ana metne bir takım katkılar sağlamışlardır. Nahivde önemli bir yer teşkil eden tanımlar el-Unmûzec՚de kısmen zikredilmiştir. Kısmen de zikredilmemiştir. el-Unmûzec՚de bahsi geçmeyen bazı tanımları şârihler yapmışlardır. el-Unmûzec՚de zikredilen tanımlar ise analize tabi tutularak herhangi bir hataya denk gelindiğinde genelde bu hatanın giderilmesi adına çözümler üretilmeye çalışılmıştır. el-Unmûzec՚de istişhâd unsurlarına yeterince yer verilmemiştir. Bu boşluk şârihler tarafından doldurularak Kur’ân-ı Kerim âyetleri, hadis ve Arap kelamı gibi istişhâd malzemeleriyle metin zenginleştirilmiştir. Nahiv konularını bütüncül bir şekilde ele alan şârihler, birden çok amaç için istişhâd malzemesini kullanmışlardır. Buna bağlı olarak nahiv bilgisinin önemli kaynaklarından olan âyet ve Arap kelâmına oldukça yer vermişlerdir. Ancak bu durum hadis için geçerli değildir. Âyet ve Arap kelâmına nazaran hadise daha az yer verilmiştir. Şârihler, tanımlarda olduğu gibi bazı yerlerde Zemahşerî՚nin konuları işleme biçimi ve ifadelerine de müdahalelerde bulunarak analist bir tutum sergilemişlerdir. Tenkit merkezli olan bu yaklaşımla okuyucuya doğru bilgi verme gayreti sergilenmiştir. Şârihlerin metotlarında sadece kurucu metne tenkit yapmak yoktur. Bazen de kurucu metne yöneltilebilecek tenkitlerin bertaraf edildiği görülmüştür.

En este trabajo se describe el estudio de la estructura y composición química por microscopía electrónica del esmalte dental humano, así como del defecto que se observa en el centro de los cristales del esmalte, llamado “línea obscura” (CDL). Las imágenes del esmalte dental fueron tomadas por microscopia electrónica de transmisión (TEM) de alta resolución (HRTEM) y de microscopía electrónica de barrido transmisión (STEM) en el modo de detección anular de la dispersión a alto ángulo (STEM-HAADF). Los dientes humanos usados en este trabajo se obtuvieron de extracciones ortodóncicas. La preparación de las muestras se realizaron por métodos metalográficos. Los resultados indican que la CDL se formo durante la amelogénesis y que es una zona con residuos de material orgánica.

Los componentes bioactivos de fuentes vegetales suelen ser inestables frente a factores como la radiación y los cambios de temperatura, lo cual implica que su conservación y manejo sea un reto. Un método para estabilizar este tipo de componentes es el secado por aspersión, que consiste en asperjar una solución líquida de forma distribuida en la cámara de secado que circula aire caliente, para eliminar el agua y obtener un polvo. El primer punto de control es durante la alimentación al equipo, ya que debe mantenerse en in intervalo de temperatura o de lo contrario podría generar una modificación no favorable en los componentes termolábiles. El objetivo del trabajo fue predecir a partir de cálculos numéricos de la transferencia de calor en el contenedor de alimentación del sistema de secado, la afectación del tiempo finito de evaluación, y los coeficientes convectivos y conductivos de transferencia de calor sobre el historial térmico, además de los requerimientos de suministro de energía para mantener la temperatura controlada.

Una de las potenciales amenazas de los desechos mineros es la dispersión de polvos tóxicos, los cuales pueden ser inhalados por las personas, poniendo en riesgo su salud. Esta investigación se centra en el estudio de partículas magnéticas contenidas en una muestra de desechos mineros provenientes del municipio de Mineral de la Reforma Hidalgo, México. En este estudio, una muestra representativa fue atricionada y secada para realizar un análisis granulométrico por tamizado. Posteriormente se llevó a cabo una separación magnética de cada muestra para determinar la concentración de partículas magnéticas. Se obtuvieron muestras de partículas fuertemente magnéticas y medianamente magnéticas, estas fueron analizadas por difracción de rayos X, espectroscopía infrarroja y microscopía electrónica de barrido. Los resultados de este estudio servirán para determinar la viabilidad de construir un separador magnético que permita mejorar el proceso de tratamiento de estos desechos, a fin de disminuir el impacto que tienen en el medio ambiente.

Las características de la espectrometría de masas (EM) la han elevado a una posición destacada entre los métodos analíticos debido a su sensibilidad inigualable, límites de detección, rapidez y su combinación con la cromatografía (Milman, 2015). aplicaciones biotecnológicas de algunos complejos proteicos requieren información detallada sobre su estructura y composición, lo que puede ser difícil de obtener en el caso de las proteínas de origen natural (Kaldmäe et al., 2019). Importante ejemplo es la ficocianina (FC), aislada de microorganismos fotosintéticos. Rivera et al (2021), exponen que este metabolito genera efectos biológicos con alto poder antioxidante, antiinflamatorio, anticancerígeno e incluso ha demostrado potencial antiviral y su posible uso en trastornos relacionados con el brote de COVID-19. A pesar de su utilidad, se desconoce en gran medida estructuras e interacciones de sus subunidades centrales. Por lo que, se realizó una revisión bibliográfica del análisis por EM para revelar su estabilidad e identificar sus homólogos arquitectónicos.

La incorporación de materiales novedosos a la ingeniería de tejidos ha ayudado a resolver problemas específicos de regeneración ósea. El óxido de grafeno (GO), se ha utilizado como refuerzo mecánico en biomateriales con matrices cerámicas o poliméricas. En este trabajo se analiza el diseño y las propiedades mecánicas a compresión de andamios compuestos por Policaprolactona (PCL), Hidroxiapatita (HAP) y óxido de grafeno (GO), en una relación porcentual en peso de PCL (80)-HAP (20) /GO (0.1). El GO se obtuvo mediante el método de Hummers y la HAP se sintetizó por coprecipitación. Los andamios fueron sometidos a una deformación del 70% en la máquina de ensayos Univert® de la marca Cell Scale®. Una vez hechos los ensayos mecánicos, se analizan los datos para obtener las curvas esfuerzo-deformación. También se desarrolla un modelo mecánico a través del algoritmo de mínimos cuadrados de Levenberg-Marquardt en el software Comsol Multiphisics®, de donde se obtienen los parámetros del modelo que se ajustan al material diseñado.

Se adquirió la zeolita sintética comercial 13X-HP, la cual es comercializada como tamiz molecular para su aplicación en concentradores de Oxígeno. Acorde a la tabla de uso la pureza de este material es mayor al 90%, por lo que se realizó difracción de rayos X para corroborar este valor. Del mismo modo, el número “13” en el nombre es un indicativo de que el catión intercambiable presente es sodio (Na), para corroborar este resultado se realizó la caracterización por MEB-EDS para un barrido elemental de la zeolita; aprovechando la técnica se revisó la morfología de los cristales para poder correlacionarlos con los resultados de DRX y así corroborar la presencia de la estructura tipo Faujasita.

En este trabajo de investigación se realiza un estudio de dos rocas: roca zeolítica y roca fosfórica. Se realiza la caracterización de cada una mediante difracción de Rayos X, Microscopia Electrónica de Barrido, análisis químico por Fluorescencia de Rayos X. Una de las rocas zeolíticas es intercambiada por iones amonio para lograr la obtención de iones disponibles dentro de la estructura de los cristales de zeolita. Los resultados indican que al realizar una mezcla de estas tres rocas se logra obtener un sustrato que puede ser capaz de sustituir los fertilizantes químicos para los diferentes tipos de plantas, basándonos en que la nutrición de estas dependen de tres elementos esenciales como el Nitrógeno, Fósforo y Potasio, estos proporcionan el material de construcción para los tejidos vegetales, las proporciones entre ellos van a variar según el tipo de cultivo; al conocer por medio de los estudios anteriormente mencionados los componentes de cada elemento en estas rocas podemos construir un sustrato según lo que se desea cultivar.

El nitrito de sodio se ha utilizado durante muchos años para inhibir la corrosión de los metales por el agua. Al funcionar como un inhibidor anódico. El nitrito de sodio oxida los iones ferrosos a iones férricos en las superficies de hierro y acero para producir una película adherente muy delgada de óxido férrico en las áreas anódicas. En el presente estudio se evalúa el comportamiento electroquímico de un inhibidor base nitrito, en agua desmineralizada, en un acero estructural con 0.21% C, en el intervalo de 0 a 800 ppm de nitritos (0.44, 0.88, 1.76, 3.52 y 5.28 ml/l de Inhibidor) a 55°C, mediante resistencia a la polarización (Rp) y curvas de polarización.  Los resultados muestran que la presencia del inhibidor reduce la velocidad de corrosión, alcanzando un máximo a 0.88 ml/l pero vuelve a aumentar ligeramente en la presencia de más inhibidor.
