Importance of development of STEM education for petrology and mineralogy
Authors: Takebayashi Tomohiro , Kumano Yoshisuke
Published: November 2021

Rocks and minerals are very important materials for studying Earth Sciences. They are used to investigate the planetary history and evolution and are utilized as resources to support our lives. At present, it is critical for all countries to secure a stable supply of mineral resources, and it is necessary to understand the deposits and the growing mechanisms of minerals. In Japan, elementary and junior high school students study igneous and sedimentary rocks and some other kinds of minerals. In this research, we conducted a questionnaire for 154 Japanese junior high school students to investigate their 1) knowledge of minerals, and 2) petrology and mineralogy with respect to usefulness of rocks and minerals to our living. First, about 95% of the students could answer the names of the stone, including those who mainly answered jewel names. However, ~56% students could not answer the benefits of minerals.In high school, 36% students learned Basic Earth Sciences and 1.2% learned Earth Sciences (MEXT 2017). There is concern that most of the Japanese people have few opportunities to learn Earth Sciences. As NGSS showed in 2013, Earth and Space Science are major fields of STEM learning. Conclusively, it is necessary to stop memorizing subjects and instead modify the Earth Sciences with respect to STEM education. In this paper, we discuss the student’s attitudes towards petrology and mineralogy so as to propose the Earth STEM education.

The IR transmittance spectrum of an isotopic mixture of chlorodifluoromethane (CHF2Cl, Freon-22) with a 33% fraction of 13C and a natural ratio of chlorine isotopes was measured in the frequency range 1400-740 cm–1 with a resolution of 0.001 cm–1 at a temperature of 20C. An ab initio calculation of the structure and sextic potential energy surface and surfaces of the components of the dipole moment has been carried out by the the electronic quantum-mechanical method of Möller-Plesset, MP2/cc-pVTZ. Then the potential was optimized by replacing the harmonic frequencies with the frequencies calculated by the electronic method of coupled clusters, CCSD(T)/aug-cc-pVQZ. The fundamental and combination frequencies were calculated using the operator perturbation theory of Van Vleck (CVPTn) of the second and fourth order (n=2,4). Resonance effects were modeled using an additional variational calculation in the basis up to fourfold VCI excitation (4). The average prediction error for the fundamental frequencies of the 12C isotopologues was ~1.5 cm–1. The achieved accuracy made it possible to reliably predict the isotopic frequency shifts of the 13C isotopologues. It is shown that the strong Fermi resonance ν4/2ν6 dominates in the 12C isotopologues and is practically absent in 13C. The literature assumption [Spectrochim. Acta A, 44: 553] about the splitting of ν1 (CH) due to the resonance ν1/ν2+ν7+ν9 is confirmed. The coefficients of the polyadic quantum number are determined. The analysis made it possible to carry out a preliminary identification of the centers of the vibrational-rotational bands of isotopologues 13CHF235Cl и 13CHF237Cl in the spectrum of the mixture in preparation for individual analyzes of the vibrational-rotational structures of individual vibrational transitions.

We report Zeeman infra-red spectroscopy of electronic-nuclear levels of 5I8 →5I7 transitions of Ho3+ in the C4v(F−) centre in CaF2 with the magnetic field along the ⟨111⟩ direction of the crystal. Transitions to the lowest 5I7 state, an isolated electronic doublet, and the next group of states, a pseudo-quadruplet consisting of a doublet and two nearby singlets, exhibit strongly non-linear Zeeman splittings and intensity variations. Simulated spectra based upon a crystal-field analysis give an excellent approximation to the data, illustrating the strong predictive ability of the parametrised crystal-field approach. Anti-crossings in the hyperfine splittings, the basis of quantum information storage in rare-earth doped insulating dielectrics, are also predicted.

The current paper demonstrates theoretical analysis of two types of spectral curves for several configurations of system of two-level light emitters, considering the influence of local field and close environment inside a transparent medium. Probe field absorption spectra and resonant fluorescence spectra are calculated under excitation of a strong monochromatic cw laser. The sensitivity of absorption and emission optical spectroscopy method is compared for revealing the effects of the medium on individual emitters and their ensembles. Spectral curves were calculated for model emitters considering local field influence of a transparent dielectric medium and local electron-phonon interactions, which determined the response of the emitters to an external laser field and effective relaxation mechanisms. The calculation formalism is based on a semiclassical approach, while the relaxation processes associated with the phonon contribution are introduced phenomenologically with references to other studies.
Gender Transformation of Kwan Yin in Central China: The Mother Stereotype
Authors: Zhang Muyi
Published: November 2021

Kwan Yin, although typically depicted as female in Chinese literature and artworks, is originally a male deity Avalokite?vara in India. This essay examines the process, reason, and impact of Kwan Yin’s feminization in the ancient Chinese context and argues that her gender transformation is a transformation to the mother stereotype. The essay mainly relies on primary source of Buddhist texts and folklores of Kwan-Yin in China and secondary sources researching the gender transformation of Kwan-Yin through historical and sociological lens. The essay concludes that while the female Kwan Yin’s popularity could be seen as gender empowering, the mother stereotype she and female deities of other religions embody in fact dismisses woman’s individual value.

Published: November 2021

Abstract: Today in the rapid competition of the industries to get the best quality of the product in the minimum required time is the main aim of industries. To get the best quality and maximum production most advanced machines are used. But there are no facts that use only the advanced machines, to maintain their performance is real requirement of the industries, also to give proper facilities to the workers with good environmental condition and to reduce their efforts is one of the objects to achieve the best quality and high production. Sheet metal is simply a metal formed into thin and flat pieces. It is one of the fundamental forms used in metal working and can be cut and bent into a variety of different shapes. Countless everyday objects are constructed of the material. Thicknesses can vary significantly, although extremely thin thicknesses are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate. Sheet metal also has applications in car bodies, airplane wings, medical tables, roofs for buildings (Architectural) and many other things. Sheet metal of iron and other materials with high magnetic permeability, also known as laminated steel cores, has applications in transformers and electric machines. There are three primary procedures in Layout. They are Parallel, Radial, and Triangulation. The major aim to our experiment is to study about pneumatic control system, study about double acting cylinder, study about the advantage of pneumatic hand operated valve and study about high speed blade. We are using scissors for simple sheet metal cutting. It is a manual method so that sheet metals are to be wasted sometimes because of mistakes happened such as wrong dimensions etc., and also even a simple cutting may take long time. We are using a pneumatic system for sheet metal cutting in an easy way. It is operated by a pneumatic hand lever of two ways control valve. Control valve is operated by a compressor.

Transliteration: A Magnetic Analysis
Authors: Mishra Dr. Rudra Prasad
Published: November 2021

Abstract: Machine transliteration is an important problem in an increasingly multilingual world as it plays a critical role in many downstream applications such as machine translation or cross-lingual information retrieval systems. There is now a vast amount of information accessible via the Internet where a lot of regional and cultural information is put on the World Wide Web in different languages and scripts. There are more that six thousand living languages in the world. Adding to the diversity is the fact that some languages are written in different scripts in different regions of the world. The multitude of foreign languages and mutually incomprehensible scripts of the same language pose a barrier to information exchange as we cannot all learn every language or script in use worldwide. Therefore, if we can get around the language barrier or at least the script barrier, we can access much more of the world's culture and can explore its abundant richness.

En los sistemas de producción porcina, uno de los puntos críticos que deben ser atendidos con estricto rigor, es la salud de los cerdos. La salud, es un componente estructural del bienestar animal y refleja un estado óptimo de los animales, lo que repercute directamente en un mayor desempeño productivo y mejores condiciones de desarrollo. Uno de los eslabones más frágiles de la salud de los cerdos, es la presencia de enfermedades infecciosas más importantes, las cuales pueden representar pérdidas hasta del 100 % de la producción, por lo cual, debe ser un tema de atención constante, y continuamente vigilado por el Médico Veterinario Zootecnista y los productores, en perfecta coordinación con las autoridades sanitarias oficiales. En la actualidad, la implementación de mejores prácticas en la cadena productiva es de interés para productores y consumidores. El control de las enfermedades infecciosas debe ser un tema de colaboración entre los diferentes actores del entorno y ser considerado un bien público, ya que las repercusiones negativas, pueden ser desde el nivel local hasta mundial. En la presente revisión, se abordará la temática relacionada con las principales enfermedades infecciosas que ponen en riesgo la salud porcina, el impacto, las principales aportaciones realizadas por el Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias (INIFAP) en sus 35 años de vida, específicamente en el Centro Nacional de Investigación Disciplinaria en Salud Animal e Inocuidad (CENID-SAI), anteriormente conocido como el emblemático CENID-Microbiología o Palo Alto.

Actores, territorios y conflictos en políticas administrativas de la pesca artesanal. El caso de la zona contigua en la Region de Los Lagos y Aysén, sur de Chile
Authors: Alvarez Burgos Catalina , Gajardo Cortés Claudio , Ther Ríos Francisco
Published: November 2021

Durante siglos han existido desplazamientos de habitantes entre la Isla Grande de Chiloé, sus alrededores y el Archipiélago de las Guaitecas. Posterior a la regionalización del país y luego de las actividades pesqueras, los trayectos de pescadores de la región de Los Lagos hacia Aysén debieron gestionarse bajo una figura política y administrativa. Ésta incluye una zona contigua donde los gobiernos regionales negocian compromisos y compensaciones y una mesa público privada que define, desde el punto de vista político, científico, empresarial y pesquero-artesanal, la extracción de recursos en la zona. El presente trabajo describe las relaciones y estrategias que se despliegan en torno a ésta figura y la mesa de trabajo, identificando para ello a los actores, sus contextos discursivos y las dimensiones histórico-culturales. La capacidad de agencia en las prácticas y discursos de los actores da cuenta de un vínculo entre planos sociopolíticos y socio territoriales que, constituyendo una verdadera interfaz social, cuestionan la identificación dicotómica entre el Estado y las sociedades así como la verticalidad predominante en la visión y elaboración de las políticas públicas permitiendo nuevas lecturas y reflexiones tendientes a elaborar alternativas bajo una mirada política actualizada.
Turismo y patrimonio desde el cerco del acontecer
Authors: Rodriguez Isabel
Published: November 2021

¿Desde cuándo lo que vemos son interpretaciones y versiones de lo viejo? Si por un lado, el legado es inequívocamente complejo porque simboliza el devenir de la imparable metamorfosis del territorio y sus gentes; y por otro lado, la intensidad de las prácticas turísticas han penetrado los entre pliegues de los lugares, reconfigurándolos con  fuertes transformaciones que los habilitan para la visita. Entonces, necesariamente, la relación patrimonio y turismo condensa uno de los grandes retos de estos tiempos, pues afecta a la herencia en su más amplio sentido, la reconfiguración turística de los lugares. El territorio retiene en formas materiales las surgencias de significados cambiantes en el tiempo, cristalizando en sus paisajes los actos y decisiones labradas por el quehacer del hombre. Una herencia única con las mismas imágenes que se dicen de formas diferentes y, por supuesto, con significados en continua transformación: el continuo resultado del arte por excelencia del saber hacer, de la acción y el conocimiento, de la imperiosa necesidad del actuar y del conocer consecuente que obliga a un eterno reinicio; a partir del paisaje y su estudio, se explicitan las expresiones de ese saber hacer, de ese arte del diseño colectivo de nuestra espacialidad.

La creación de la película Nostalgias del Far West (1987) comienza con una discusión. Probablemente las tensiones en el rodaje son parte inherente de la naturaleza de una creación colectiva y para el colectivo Cabo Astica —uno de esos que proliferaron en el audiovisual chileno durante la dictadura militar— la disyuntiva previa a la filmación oscilaba entre la ficción y el documental. La elección por el género debía ser la que más se ajustara para retratar al poeta Jorge Teillier, objeto de la segunda película de este colectivo integrado por Sergio Navarro, Vicente Parrini, Ricardo Carrasco, Felipe Tirado y Gonzalo Duque

The misconception is a problem in learning and it is very necessary to solve it so that learning is better. Students who are identified with misconceptions on material concepts can make it difficult for them to believe new concepts that are true. The purpose of this study is to identify the existence of misconceptions in students in an ecosystem material concept that they have studied previously. This study uses a descriptive method with a quatitative approach. The research was conducted at Senior High School (SMA) in Sukabumi Regency. The subjects studied were 36 students of class XI MIPA 5. The instrument used was 45 multiple choice questions with the help of the Certainty of Response Index (CRI). The results showed the understanding of students in the percentage of conceptual understanding (PK), understanding the concept of being unsure (PKKY), Misconception (M), and not knowing the concept (TTK) were 20%, 6%, 32%, 42%. The highest misconception percentage at level 1 after testing was at the indicator describing the relationship between ecosystem components (60%), level 2 understanding the pattern of interactions between organisms (53%), and the lowest on indicators showing succession definition (12%). Therefore, misconceptions among students in ecosystem material need to be eliminated by choosing the right method, learning model, and approach.

Sentiment Analysis on Social Media using Machine Learning Approach
Authors: Omuya Erick , Okeyo George , Kimwele Michael
Published: November 2021

Social media has been embraced by different people as a convenient and
official medium of communication. People write messages and attach
images and videos on Twitter, Facebook and other social media which they
share. Social media therefore generates a lot of data that is rich in
sentiments from these updates. Sentiment analysis has been used to
determine opinions of clients, for instance, relating to a particular
product or company. Knowledge based approach and Machine learning
approach are among the strategies that have been used to analyze these
sentiments. The performance of sentiment analysis is however distorted
by noise, the curse of dimensionality, the data domains and size of data
used for training and testing. This research aims at developing a model
for sentiment analysis in which dimensionality reduction and the use of
different parts of speech improves sentiment analysis performance. It
uses natural language processing for filtering, storing and performing
sentiment analysis on the data from social media. The model is tested
using Naïve Bayes, Support Vector Machines and K-Nearest neighbor
machine learning algorithms and its performance compared with that of
two other Sentiment Analysis models. Experimental results show that the
model improves sentiment analysis performance using machine learning
techniques.
Preventing transfusion associated hyperkalemia in pediatric cardiac surgery : Measure The Levels of Potassium in Packed Red Blood Cells Before Using – invited Commentary
Authors: Budak Ali Baran
Published: November 2021

The authors present an revolutionary study aiming to evaluate the effect
of alterations in potassium concentrations in transfused packed red
blood cells (PRBC) on neonate and infant potassium levels after
congenital cardiac surgery. By establishing a strict protocol which
restricts the rate of transfusion, the age of the transfused PRBC, and
not transfusing a PRBC with a potassium level above 15 mmol/L, they
accomplished to suggest a safe and easy way for preventing transfusion
associated hyperkalemia.

Agroforestry systems provide soil microorganisms with a rich variety of
carbon sources and a relatively stable living environment. In this
study, five planting systems were investigated; a pure poplar (Populus ×
euramericana ‘Nanlin 895’) plantation (P) system, a pure crop (wheat
[Triticum aestivum L.] and soybean [Glycine max (Linn.) Merr.])
(WS) system, a poplar + wheat + soybean agroforestry (PWS) system, a
poplar + potherb mustard (Brassica juncea var. multiceps) agroforestry
(PP) system, and a poplar + native chicken agroforestry (PN) system. The
Biolog EcoPlate method was used to determine the vertical and seasonal
variations in soil microbial metabolic capacity. The average well color
development, carbon source utilization ability, and microbial diversity
index values were higher throughout the soil profile, and highly stable
with seasonal changes in the PWS and PP agroforestry systems.
Furthermore, the influence of the planting systems and seasonal changes
on the metabolic activity of soil microorganisms decreased with an
increase in soil depth. Overbreeding chickens in the forest reduced the
metabolic activity of soil microorganisms. It was also found that plants
influenced soil microbial metabolism through the available carbon source
types. Therefore, agroforestry systems improved the metabolic potential
of the soil microbial community. Our results demonstrated that soil
microbial communities are affected by the planting system and soil
depth. The findings enhance our understanding of the functional
diversity of soil microorganisms in agroforestry systems.

Background: Pulmonary dysfunction has been reported in patients with
β-thalassaemia major but data are conflicting and the association with
iron overload remains unclear. Objectives: To determine the pattern of
pulmonary dysfunction in patients with β-thalassaemia major and their
associations with iron overload. Methods: Subjects with β-thalassaemia
major were recruited for lung function assessment. Serum ferritin and
magnetic resonance imaging (MRI) measurements of iron status of the
myocardium and the liver were used as surrogate indexes of body iron
content. A subgroup of this cohort provided data on the longitudinal
progress of their lung function. Results: One hundred and one patients
were recruited with a mean age of 25.1 years (SD 7.9 years).
Thirty-eight (38%) and five (5%) had restrictive and obstructive lung
function deficits, respectively. There was a significant correlation
between MRI myocardial T2* relaxation time and forced vital capacity
(r=0.291, p=0.048). Higher MRI cardiac T2* relaxation time was
associated with lower risk of having restrictive lung function deficit
(Odds ratio (OR): 0.94; 95% CI: 0.89-0.99; p=0.023) after adjusting for
age, gender and BMI. Twenty-three subjects underwent lung function
reassessment with a mean follow-up duration of 13 years. Overall, they
did not demonstrate significant changes in pulmonary function over time,
3 patients who had normal lung function at baseline developed
restrictive abnormality at follow-up. Conclusions: Restrictive lung
disease is prevalent in patients with β-thalassaemia major, and the
severity correlates with myocardial iron overload. Monitoring of lung
function in this group of patients is important, particularly for those
with iron overload.
Undergraduate basic sciences and engineering students’ understanding of the concept of derivative
Authors: Haghjoo Saeid , Reyhani Ebrahim
Published: November 2021

Derivative is one of the most important topics in calculus that has many applications in various sciences. However, according to the research, students do not have a deep understanding of the concept of derivative and they often have misconceptions. The present study aimed to investigate undergraduate basic sciences and engineering students’ understanding of the concept of derivative at Tehran universities on based the framework of Zandieh. The method was descriptive-survey. The population included all undergraduate students of Tehran universities who passed Calculus I. The sample included 604 students being selected through multi-stage random cluster sampling. The measurement tool was a researcher-made test for which the reliability coefficient was obtained using Cronbach's alpha (r=.88). Inspired by Hähkiöniemi’s research, nine tasks on derivative learning were given to the students. The students’ responses were evaluated using a five-point Likert scale and analyzed using descriptive responses. The results indicated that students have no appropriate understanding of the basic concepts of derivatives in numerical, physical, verbal, and graphical contexts. Basic sciences students performed meaningfully were better in understanding the tangent line slope compared to engineering students, while engineering students performed meaningfully were better than basic sciences students in the rate of change.
Philosophy of Inequality in the Context of Post-Humanism
Authors: Rostova Natalya N.
Published: November 2021

In the article the author examines humanism criticism that does not result in post-humanism. The author shows that post-humanism is the reaction to the humanistic idea of man as the center of the world that was typical for west-European philosophy. At the same time post-humanism doe not negate the logic of humanism, but extrapolates it to the whole of non-human world. On the contrary, Russian philosophy is free from the original premises of humanism and it views the crisis of humanism in a different perspective. The author shows that Russian philosophy is not anthropocentric, but on the contrary – anthropologic. Its feature consists in viewing the man in the perspective of his ontological expansion. The idea of such ontological expansion is based on the philosophy of inequality. When west-European philosophy today conceptualizes total world democracy on the other side of man, Russian philosophy turns to the idea of metaphysical gaps that substantiate the idea of man’s freedom and anthropological necessity of self-restrictions.
