Authors: Hagan Travis , Cotilla-Sanchez Eduardo , Kim Jinsub , Silva Shashini De , Senaratne Dilan
Published: September 2022

This paper contributes to the growing body of work that aims to
characterize similarities and differences between synchrophasor data
from real-power systems and those from synthetic power systems with
emulated Phasor Measurement Units (PMUs). In particular, we survey
previous works that characterize PMU noise and analyze the impacts on
applications of these time-series data into machine learning algorithms
in the power systems domain. We benchmark these methodologies with three
datasets: data from an Oregon State University local PMU network, from
two PMUs using the same set of sensors, and from multiple-utility
interconnect-wide data. We found that it is important to consider each
signal individually when synthesizing PMU data with noise, and that the
noise needs to be adjusted by key statistical metrics.

4: Geriatric Syndromes and Diabetes
Authors: Drozdz Burke Sandra , Sikma Katie
Published: September 2022

Diabetes is a chronic condition characterized by variable levels of blood glucose. Normally, fasting blood glucose levels range from 70 to 99 mg/dl. Impaired glucose tolerance or impaired fasting glucose is now known as prediabetes; it is associated with blood glucose levels between 100 and 125 mg/dl. Diabetes, which occurs when fasting blood glucose levels are consistently at 126 mg/dl or higher, occurs frequently in the aging population. Because blood glucose levels rise insidiously, many people fail to experience symptoms of hyperglycemia until the blood glucose level is consistently well above 300 mg/dl. For this and other reasons, diabetes often goes undiagnosed for many years.
7: Steroid-Associated Hyperglycemia
Authors: Mathioudakis Nestoras , Dungan Kathleen , Baldwin David , Korytkowski Mary , Reider Jodie
Published: September 2022

Systemic steroids (glucocorticoids) are used ubiquitously in the hospital for a variety of indications. Although they have clear and wide-ranging benefits, they are also a major contributor to severe hyperglycemia. In patients with and without preexisting diabetes, steroids can exacerbate glycemic control and can make glucose management in the hospital challenging. Variability in steroid type, dose, and dosing schedules poses additional challenges to proactive adjustments in glycemic management strategies that promote safe blood glucose (BG) control and avoidance of hypoglycemia. Moreover, many patients receiving steroids have comorbid conditions or are receiving other medications that can affect glucose homeostasis. An understanding of the pathophysiology and pattern of steroid-associated hyperglycemia is necessary to guide management of hospitalized patients on steroids.
19: Emergency Department Management of Diabetes Patients with Non-crisis Hyperglycemia
Authors: Magee Michelle , Nassar Carine , Reyes-Castano John , McDonnell Marie
Published: September 2022

Annually in the U.S., adults over 18 years of age with diabetes accrue over 12 million visits to hospital emergency departments (EDs). Although the primary reason for the majority of these visits is not glycemic control, the ED setting presents an opportunity to intervene in and initiate evidence-based care for the patient with either known or previously unrecognized diabetes. Such interventions have the potential to affect both short- and long-term health-related clinical, behavioral, and economic outcomes, including resources utilization, and will be the main focus of this chapter.

Authors: Chen Kelvin , Purba Ronsen , Halim Arwin
Published: September 2022

Bidirectional Long Short Term Memory (Bidirectional LSTM) is a machine learning technique with the ability to capture data context by traversing backward data to forward data and vice versa. However, the characteristics of stock data with large fluctuations, high dimensions and non-linearity become a challenge in obtaining high stock price prediction accuracy values. The purpose of this study is to provide a solution to the problem of stock data characteristics with large fluctuations, high dimensions and non-linearity by combining the Complete Ensemble Empirical Mode Decomposition With Adaptive Noise method for exogenous features (XCEEMDAN), Bidirectional Long Short Term Memory (LSTM), and Splines. The predicted data will go through normalization and preprocessing using XCEEMDAN then the XCEEMDAN decomposition results are divided into high and low frequency signals. The bidirectional LSTM handles high frequency signals and the Spline model handles low frequency signals. The test is carried out by comparing the proposed XCEEMDAN-Bidirectional LSTM-Spline model with the XCEEMDAN-LSTM-Spline model using the same parameters and changing the noise seed randomly 50 times. The test results show that the proposed model has the smallest RMSE average value of0.787213833 while model which is compared only has the smallest RMSE average value of 0.807393567.

Popular Phonetic Mapping in The Qur’an and Its Implications on Teaching Arabic for Non-Native Speakers
Authors: Thohir Muhammad , Dzakiruddin Muhammad
Published: September 2022

The advantages of Arabic as the language of the Qur’an are its variety of sounds in each word with derivations in various forms and meanings. This study aimed to map popular phonetics with repetition rate in the Qur'an in order to build implicative concepts in Arabic learning for non-native speakers. The research used a qualitative approach with the type of literature research. As a preliminary research, data were obtained through documentary techniques from the Qur'an and Surah al-Wāqi'ah was taken as a data sourcebecause it represented the criteria as a popular surah. The analysis used a content analysis approach through the stages of condensation, presentation and conclusions. The results of the study was found that popular phonetics had vocal repetitions of 1,015 short vowels, 246 long vowels and 1,512 consonants. The results showed that the frequency of repetition of both vowels and consonants in the Qur’an had a phonetic sequence pattern from front to back, which was in line with Chomsky’s universal rules and the natural order hypothesis of Krashen. In addition, the results were complemented by the hypothetical presupposition of the implications in Arabic learning for non-native speakers, both linguistically, psychologically, and pedagogically.

Authors: Afiah Irma Nur , Nakashima Hiroki , Loh Ping Yeap , Muraki Satoshi
Published: September 2022

Studies investigating the walking patterns of elderly men are well documented, however, there has been no investigation of the gait parameters that specifically reflect the walking motion of elderly men. This study aimed to identify reliable gait parameters to represent the walking motion of elderly Japanese men. 33 elderly men (65 to 74.9 years old) and 20 very elderly men (≥ 75 years old) participated. A 3-dimensional motion analysis system was used to collect kinematic data and 52 gait parameters were analyzed namely; spatiotemporal gait, joint angle, and angular velocity parameters (peak value and peak timing at the hip, knee, and ankle joints. Our results showed that walking speed, cadence, walk ratio, gait cycle, peak joint angle timing, and angular velocity parameters significantly differ between elderly men and very elderly men. Delayed peak timing in the joint angle occurred during the terminal stance phase and pre-swing phase. The accurate parameters for walking motion in old Japanese men as they age may result from the peak timing of joint angle parameters and the peak value of angular velocity parameters.

Published: September 2022

This study aims to analyze silica's morphological characteristics and electrical properties based on the river and coastal sand. Iron samples were taken from Sompang river sand, East Lombok and Coastal Sand from Gading, Mataram City. The silica was synthesized using the sol-gel method with a sintering temperature variation of 100 to 175 ℃. Morphological characteristics samples analysis was done using SEM-EDX. The electrical properties of iron sand included measuring the dielectric constant using the parallel plate method. Furthermore, the resistivity was measured using the two-point probe method. In the silica-based on river sand sample, the resistivity value was inversely proportional to the sintering temperature. In contrast, the resistivity value of silica based on the coastal sand sample was directly proportional to the sintering temperature. Silica-based on river sand has a resistivity of about 7.1'104 Wm at a sintering temperature of 100℃ and 3.5'104 Wm at a sintering temperature of 175℃. Silica-based on river sand has a resistivity of about 1.8'104 Wm at a sintering temperature of 100℃ and 7.1'104 Wm at 175℃. This research is a preliminary study on the electrical properties of natural sand-based silica to improve understanding of the physical properties of silica to be used in technological applications, such as sensors. Furthermore, the dielectric constant value in the river sand sample was directly proportional to the sintering temperature. However, the dielectric constant in the coastal sand sample was inversely proportional to the sintering temperature. Silica-based on river sand has a dielectric constant of about 1.02'102 at a sintering temperature of 100℃ and 1.18'102 at 175℃. Silica-based on coastal sand has a dielectric constant of about 1.97'102 at a sintering temperature of 100℃ and 1.15'102 at 175℃.

Un diario de la vejez: La vida a ratos, de Juan José Millás
Authors: Prósperi Germán Guillermo
Published: September 2022

La obra de Juan José Millás se inscribe con facilidad en los debates acerca de los alcances de lo metafictivo y sus modulaciones tales como la escritura autofictiva. Ese proceso autofigurativo ya practicado por el autor valenciano en textos como El mundo (2007), encuentra en la publicación de La vida a ratos (2019) un nuevo ejercicio de interrogación, esta vez orientado hacia la escritura de un diario de vejez.
En este trabajo analizamos las marcas específicas de esa categorización a partir de su puesta en relación con otras especies textuales con las que dialoga, tales como la mencionada autoficción, la antificción y el diario de escritor. Nos preguntamos además por la posibilidad de leer esta ficción en tanto ejemplo de estilo tardío.
“Halléla flaca, vieja, sin dientes, arrugada y muy otra en su parecer“ (II, 3, 6): Agencia femenina y senectud en el Guzmán de Alfarache
Authors: Vila Juan Diego
Published: September 2022

El sino de Marcela, madre de Guzmán de Alfarache, es espejo quebrado donde se funden los tiempos de esplendor y decadencia, es reflejo de lo que fue, y podría haber logrado, y amargo anticipo de toda limitación ulterior que el hijo pícaro habrá de experimentar. Ya que la tragicidad del segundo abandono en el cual la madre quedará expósita y desamparada de toda protección filial reverbera culposa en la evocación del galeote escritor de una paráfrasis bíblica (Lucas, 23, 31) que él sólo juzga relevante a su respecto cuando cae, con muchos menos años, en desgracia: ‘si así siento aqueste trabajo, si esto pasa en el madero verde, ¿qué hará el seco?’ (II, 3, 8).
En los estertores de la aventura biográfica narrada, la contextual y elusiva figuración de la anciana madre susurra que el esfumado de un discurso diferencial sobre su vejez debe acrisolarse en múltiples ángulos: la diferencia genérica, la diversa valoración de los constituyentes familiares y la distancia etaria de cada cual. Ya que en esta constelación de tensiones significantes lo que se dirime, con las viñetas de Marcela decrépita, son los márgenes de libertad y agencia que cada cultura está dispuesta a tributar a sus mayores.
Modulaciones imaginativas de la infancia en la poesía de Luis García Montero y Fernando Beltrán
Authors: Sierra Gabriela
Published: September 2022

En el presente artículo, analizamos Poemas de Tristia (1982) y El jardín extranjero (1983) de Luis García Montero (Granada, 1958) y Aquelarre en Madrid (1983) y Gran vía (1990) de Fernando Beltrán (Oviedo, 1956) desde la categoría que denominamos figuraciones de la niñez o dibujos imaginativos de infancia (Sierra, 2021).

Dicha selección de textos nos permite establecer algunos puntos de encuentro entre sus poéticas particulares porque en ambos casos, desde sus publicaciones iniciales, la infancia se encuentra presente. En la poética de García Montero se vincula con la descripción del entramado de la ciudad natal y con las imágenes de la posguerra española, en el caso de Beltrán, se vincula con el deambular por diversos espacios de Madrid. En esta línea, leemos el cruce de una infancia visible y una infancia imaginaria que se proyecta desde los poemas.

Authors: Moreno Griselda , Graieb Augusto , Tack Jerónimo , Martínez Agustina , Zurita Eugenia , Cocchiararo Luciana , Liberto Romina
Published: September 2022

En este artículo describimos los sucesivos cambios en la planificación de la materia Biología para Ciencias de la Salud (Ciclo básico de Salud, Universidad Nacional Arturo Jauretche) y la racionalidad para realizarlos. Se describen los aspectos fundamentales de la propuesta didáctica, haciendo foco en la propuesta híbrida del primer cuatrimestre de 2022, pero estableciendo relaciones y comparaciones con las propuesta presencial (2019) y totalmente virtual (2020 y 2021).

Entre los aspectos tratados se encuentran: la selección y jerarquización de los contenidos, los materiales para les estudiantes, lo que se espera del trabajo cotidiano de docentes y estudiantes en cada una de las propuestas, la enseñanza de los modos de conocer y la evaluación. A modo de reflexión final consideramos que aun con la idea de sostener el mismo paradigma de enseñanza-aprendizaje se impone la revisión, adecuación y modificación de la propuesta pedagógica de la asignatura cuando existen cambios en las modalidades de dictado. Estos cambios impactaron tanto sobre los contenidos disciplinares como los modos de conocer que resultan diferenciales para las tres modalidades transitadas.
Reflexiones sobre algunas estrategias didácticas y evaluativas en modalidad mixta para implementar en la universidad en contexto de masividad
Authors: Olmedo Luciana , Torrieri Rocío , Pappalardo Brenda , Mancini Verónica
Published: September 2022

La pandemia por COVID-19 y el consecuente traslado, en muchos casos, de una educación superior totalmente presencial hacia una completamente virtual, ha dado lugar a un mayor nivel de reflexión por parte de los docentes sobre sus propias prácticas de enseñanza y al reconocimiento de que no existe una sola forma de enseñar. En la búsqueda de una mejora de la educación universitaria, la virtualidad posiblemente haya llegado para quedarse y complementarse con la presencialidad, la cual se encontraba fuertemente instalada previo a dicho contexto. A esta situación de cambio, se adiciona el proceso de masificación que se está dando en muchas universidades del país, sin vista de detenerse en el corto plazo. Por este motivo, el presente trabajo, realizado en el marco del seminario “Estrategias didácticas para la enseñanza de las ciencias”, de la Especialización en Docencia Universitaria de la Universidad Nacional de La Plata, se focaliza en la identificación de posibles estrategias didácticas y evaluativas y su profundo análisis, para ser utilizadas en una modalidad mixta de educación universitaria en contexto de masividad estudiantil, y así contribuir en la mejora de las prácticas docentes actuales en concordancia con una forma problematizadora de la enseñanza.

Published: September 2022

En el presente escrito se exponen los resultados del análisis de los materiales educativos dispuestos para la asignatura electiva Inglés Comunicacional. La misma se dictó con modalidad de aula invertida por primera vez en el segundo semestre de 2021 para estudiantes de las carreras de ingeniería de la Facultad de Ingeniería y Ciencias Agropecuarias de la Universidad Nacional de San Luis. La narrativa aborda el análisis de los materiales desde la mirada del docente y desde la mirada de los estudiantes, ambos pilares fundamentales en la evaluación de una propuesta educativa. Si bien los resultados dan cuenta de una propuesta sólida y acorde a los fines planteados, la interpretación en conjunto desde ambas perspectivas permitió esbozar desafíos pendientes tendientes a optimizar algunos aspectos de la asignatura para el próximo dictado en el segundo semestre de 2022.

Este artigo aborda reflexões sobre a importância de educar o homem deste tempo para os valores, o que seria encontrar um referencial e um critério que garanta o agir humano e consequentemente um sentido para a própria vida. A presente pesquisa tem cunho teórico, sendo realizada através de um levantamento bibliográfico, em que o foco será a relevância da categorização de valores proposta por Viktor Frankl em sua teoria para a formação humana. Para Frankl, os valores são os meios por onde o ser humano realiza sentidos na vida, eles podem ser criativos, quando o homem “ entrega” ao mundo seus talentos, vivenciais, quando o homem “ recebe” do mundo experiências de amor e contemplação do belo e por fim, os valores de atitude, quando o ser humano é provocado a adotar uma postura diante de uma situação que não pode mudar. Nesse sentido, a educação abre o campo visual do educando por meio da própria consciência, para as possibilidades de realização de valores e sentido da vida.

OBJECTIVE

The purpose of this study was to characterize the relationship of diet and management factors with the glandular gastric mucosal microbiome. We hypothesize that the gastric mucosal microbial community is influenced by diet and management factors. Our specific objective is to characterize the gastric mucosal microbiome in relation to these factors.

ANIMALS

57 client-owned horses in the southern Louisiana region with and without equine glandular gastric disease.

PROCEDURES

Diet and management data were collected via a questionnaire. Gastroscopy was used for evaluation of equine gastric ulcer syndrome and collection of glandular mucosal pinch biopsies. 16S rRNA amplicon sequencing was used for microbiome analysis. Similarity and diversity indices and sequence read counts of individual taxa were compared between diet and management factors.

RESULTS

Differences were detected in association with offering hay, type of hay, sweet feed, turnout, and stalling. Offering hay and stalling showed differences in similarity indices, whereas hay type, sweet feed, and turnout showed differences in similarity and diversity indices. Offering hay, hay type, and sweet feed were also associated with differences in individual sequence read counts.

CLINICAL RELEVANCE

This study provides preliminary characterization of the complex relationship between the glandular gastric microbiome and diet/management factors. The ideal microbiome to promote a healthy glandular gastric environment remains unknown.
Detoxification and adaptation mechanisms of Trichoderma atroviride to antifungal agents

Filamentous fungi are crucial for recycling of organic material in nature. In natural habitats, they cope with many stress factors and therefore their adaptation ability to various conditions is very high. Trichoderma sp., fungi used in agriculture as biocontrol agent, are exposed to a variety of toxic molecules including pesticides and fungicides. They have to fight with toxic molecules using stress adaptation mechanisms known as the stress response. Adaptation of fungi to stress, especially to chemical stress, is not well studied in environmental fungal strains. Moreover, the adaptation process presents a risk of resistance mechanism induction to antifungal agents. Such resistant strains could be spread in the environment. This work aims to contribute to the knowledge of the adaptation process spread throughout the fungal kingdom. Transcriptional response of ABC transporters, the main detoxification efflux pumps of subfamily B and G in presence of antifungal agents, is shown. On the other hand, as azoles are the most commonly used antifungal structures in clinical practice and agriculture, changes in important fungal ergosterol biosynthesis genes as a result of their exposure to various azoles structure are highlighted.
Multifunctional Role of Chitosan in Farm Animals: A Comprehensive Review

The deacetylation of chitin results in chitosan, a fibrous-like material. It may be produced in large quantities since the raw material (chitin) is plentiful in nature as a component of crustacean (shrimps and crabs) and insect hard outer skeletons, as well as the cell walls of some fungi. Chitosan is a nontoxic, biodegradable, and biocompatible polyglucosamine that contains two essential reactive functional groups, including amino and hydroxyl groups. This unique chemical structure confers chitosan with many biological functions and activities such as antimicrobial, anti-inflammatory, antioxidative, antitumor, immunostimulatory and hypocholesterolemic, when used as a feed additive for farm animals. Studies have indicated the beneficial effects of chitosan on animal health and performance, aside from its safer use as an antibiotic alternative. This review aimed to highlight the effects of chitosan on animal health and performance when used as a promising feed additive.
Comparison of the Quality of Mountain Sheep Milk Obtained from Animals Kept on a Natural and Organic Mountain Pasture
Authors: Kawęcka Aldona , Radkowska Iwona
Published: September 2022

The purpose of this study was to evaluate the quality of mountain sheep milk obtained from animals kept on mountain pastures: natural and organic. The experimental procedure was conducted under production conditions, during annual grazing of mountain sheep on two mountain pastures in the region of the Polish Carpathians: on organic pasture certified for organic farming and natural mountain pasture belonging to the National Park. This study showed greater plant species diversity in the organic mountain pasture, but its yielding was lower than that of the natural pasture. The sward of the natural pasture was characterised by lower dry matter and fibre content but contained more total protein. The type of pasture did not affect the basic composition of the milk of mountain sheep, while differences were found in terms of acidity, alcohol number, fatty acid profile of fat and milk protein fractions. Milk obtained from sheep grazed on organic pasture was characterised by a higher proportion of medium chain fatty acids, as well as polyunsaturated fatty acids, and also essential unsaturated fatty acids, both linoleic acid, α-linolenic acid, γ-linolenic acid and arachidonic acid. In milk originating from the natural mountain pasture, a higher proportion of monounsaturated fatty acids, docosahexaenoic acid and the CLA c9-t11 isomer was found. The composition of milk protein fractions varied according to the location of grazing: milk from sheep grazing on natural pasture had a higher content of whey fractions, important for consumer health, milk from organic pasture had a higher content of κ-casein, of greatest importance in dairy processing technology. The floral composition of the pasture had an influence on the quality of sheep milk in relation to the fatty acid profile of fat and protein fractions of milk, which is important in terms of both the health-promoting and technological aspects of the raw material and may affect the quality of products made from it.
Investigating the effect of number of metal electrodes on performance parameters of AlGaN MSM photodetectors

Published: September 2022

In most past studies, MSM (Metal–Semiconductor–Metal) detectors with the varying area have been investigated for varying number of fingers (metal electrodes) of equal width (W) and spacing (S). Therefore, there is a need to investigate fixed area MSM detectors with varying number of fingers as there are few reports on electrical analysis of larger electrode spacing dimensions. In the current work effect of variation in the number of fingers is studied for two types of Al0.5Ga0.5N/AlN/Sapphire based fixed area MSM detectors. Comparative performance analysis between (S = W) and (S = 2W) based detectors is carried out for photocurrent, dark current density and transient response. I–V characteristics, structure diagram plots are generated using the TCAD Silvaco simulator. It has been observed that S = W detectors exhibit higher photocurrent and lower dark current density is shown by S = 2W designs. Therefore, simulation outcomes can be beneficial for selecting suitable MSM detector for reliable, high-speed optical communication and switching applications.
