SiO2 Dielectric Micro-Pattern Layer for Solar Cell Application
Authors: Dinh Lam Nguyen
Published: October 2022

Micro-patterns were created in a silicon dioxide (SiO2) dielectric layer (called SiO2 dielectric micro-pattern layer) via the photolithography and dry etching techniques. The SiO2 dielectric micro-pattern layer was utilized as an antireflection layer for solar cell application. The influences of structure of micro-pattern on the optical and electrical characteristics of solar cell were also investigated in detail. An improved performance of the GaAs solar cell by combination of antireflection coating layers and micro-pattern was observed. An enhancement in short circuit current density of 7.5% and conversion efficiency (about 1.2% absolute) were achieved in a cell coupling with the SiO2 dielectric 4 Î¼m period micro-pattern layer compared to those of a reference cell. The influences of the SiO2 dielectric micro-pattern layer on other performance characteristics such as open circuit voltage and fill factor were not clearly observed. Light beam induced current measurement was also carried out to indicate the contribution of the light trapping and light scattering effects on the cell performance.
Impregnation of Activated Carbon in Polyurethane Foam for Enhanced Solvent and Oil Adsorption from Water

Published: October 2022

This study illustrates the modification of the Poly-Urethane Foam (PUF) prepared from the Tung Oil (TO) and later impregnating it with varying ratio (~ 1 to 5 w/w%) of Activated Carbon (AC) which enable this modified entity to act as an effective adsorbent for the solvent and oil removal from the water. After its modification, it was found that the PUF impregnated with 5 w/w% AC displayed an enhanced solvent and oil adsorption capacity. The reusability of the adsorbent was observed to decrease with increasing number of cycles. Furthermore, the adsorption conduct was calculated in a batch-type process and validated using equilibrium and kinetics study. Here, the surface-modified PUF sorbent was characterized employing Scanning Electron Microscopy (SEM) and Contact Angle (CA) wettability study. Our findings inferred that with increasing AC ratio in the foam, its pore size and CA increases thereby enhancing the adsorption capacity making this proposed study to be more expedient for sustainable environment safety.

Published: October 2022

Polyvinyl Alcohol (PVA) capped Ag nanoparticles (AgNPs) formed through reduction of Silver Nitrate (AgNO3) by Sodium Borohydride (NaBH4) were studied for different PVA concentrations (C, %w/w of solution) in the bulk. Diameter (DAg) of Ag metallic core, obtained from plasmon resonance in Ultraviolet-Visible spectra, had a peak (â‰ˆ12.8 nm) at C~0.24, which almost exactly matched the gyration sphere diameter of PVA molecule (âˆ¼13 nm). Cluster diameter (Dcl), measured after a month through Dynamic Light Scattering (DLS) study, gave the number of NPs per cluster showing a dip at Câˆ¼0.24. Minimum inhibitory concentration (MIC) of AgNPs on Escherichia coli (E. coli), assayed from standard broth dilution method (CLSI M07-A8), showed MIC of 0.66 Î¼g/ml at the PVA concentration of 0.24%. Scanning Electron Microscopy (SEM) showed NP clusters accumulating over E. coli to have Dcl âˆ¼ DAg whereas those lying outside the bacteria to have Dcl âˆ¼ 3DAg, consistent with a strong size selectivity of antimicrobial efficacy.
La innovación del espacio doméstico en la Bauhaus: el papel de las mujeres en el diseño de interiores
Authors: VALDIVIESO MERCEDES
Published: October 2022

A través de dos casos de estudio, la Haus am Horn (Weimar, 1923) y la Casa del Director (Dessau, 1925), se analiza el papel de las mujeres de la Bauhaus en la concepción del espacio doméstico. Destacaron aquí tanto las estudiantes (Alma Buscher, Benita Otte), como las esposas de los maestros (Ise Gropius). Se prestó especial atención al diseño de la cocina, siguiendo las premisas de la ingeniería doméstica de racionalización del espacio (Weimar y Dessau), y del espacio infantil (Weimar), bajo los postulados de la pedagogía reformista.

Encuentros y desencuentros en la creación del personaje
Authors: CAÑADA RANGEL BENITO
Published: October 2022

Se considerará a el actor como el eje centrar de este encuentro – des – encuentro; encuentro con la técnica, la práctica y el proceso de experimentación o búsqueda de la creación del personaje (improvisación); desencuentro del actor con él mismo durante el proceso de creación del personaje, desencuentro con la técnica al enfrentarla a la práctica.

Nos centraremos en teorías como las de: Kowzan sobre el signo y el teatro; las acciones físicas de Stanislavsky y en estudios hechos por el que suscribe sobre la improvisación; dando énfasis en esta propuesta que, para lograr el momento de creación, podemos recurrir a la búsqueda y uso de los signos icónicos y miméticos tal como son señalados por Kowzan y adecuarlos por el actor para lograr la creación y caracterización del personaje, siempre utilizando la improvisación como parte sustancial en el proceso de experimentación y creación.

Se expondrán y vincularán cada uno de los de los conceptos antes citados y como se entrelazan para ayudar al actor a crear su personaje en el periodo de definición con las improvisaciones y como eso, lo ayuda a desvincularse de sus propios patrones corporales, ayudándole así a una creación integral.

Published: October 2022

Este trabajo analiza algunos de los más importantes conceptos de la dramaturgia desarrollada por Isidro Luna, quien ha dedicado más de veinte años a la producción teatral y ha reflexionado teóricamente sobre su propia obra y la realidad del teatro en esta época tardía.  Los conceptos estéticos de Luna analizados aquí configuran una dramaturgia hacker que se plantea superar el paradigma del teatro tradicional, convencional y comercial, suscitando la irrupción de otra dramaturgia que incluso aspira a superarse a sí misma. Isidro Luna (1950) trabaja desde Ecuador. Su producción teatral ha sido escenificada centenares de veces por grupos locales y nacionales. Los conceptos centrales de su dramaturgia son:  automatismo y trabajo técnico; inconsciente colectivo e inconsciente estético; la multitud, personaje principal; teatro y realidad; presentación y representación, más allá de la modernidad y la posmodernidad.

Variaciones H-KÑR. Proyecto artístico en torno a las hachas kañaris
Authors: NARVÁEZ GEOVANNY
Published: October 2022

Variaciones H-KÑR es un proyecto artístico en torno a las hachas kañaris –un objeto de metal de algunas culturas precolombinas de la parte andina, en especial de la cultura Kañari–. Tras un estudio iconográfico e interpretativo surgieron algunas hipótesis sobre las funciones utilitarias y simbólicas del hacha –denominado también tumi o cuchillo ceremonial– que comprenden implícitamente el aspecto cultural. De hecho, la cultura Kañari, que no tuvo escritura con grafías, dejó en sus objetos, el caso de las hachas, elementos significativos que nos invitan a una lectura y sobre todo a una experimentación artística. La realización de tableaux vivants, un tríptico audiovisual respecto de tres posibles usos (ritual, medicinal y bélico) conforma una parte de la propuesta. Otro componente cardinal del proyecto son las variaciones artísticas sobre ese objeto el cual se erige a partir de un comisionado de obras a dos artista: Lanner Díaz y Patricio Palomeque. De esta manera, se propicia un encuentro entre culturas (los pueblos originarios y la cultura artística actual) para reflexionar sobre saberes y técnicas, maneras de hacer y de pensar universos particulares a través del arte.

Published: October 2022

Definir, dar sentido y clasificar la composición musical y el trabajo interdisciplinario que incluye el sonido, exige un ejercicio de análisis crítico de los arquetipos dominantes conocidos como música académica, formal, contemporánea, popular, ancestral, entre otros. Buena parte de las formas de aprendizaje, transmisión y uso de estas categorías coincide con las nociones sistemáticas o intuitivas de la teoría del conocimiento que han ejercido un poder discriminatorio desde el centro a la hora de dar estatus a las organizaciones sonoras complejas o sencillas de diferentes culturas, aprobando o negando la validez de unas y otras. Se revisa brevemente corrientes musicales producto de la investigación-creación o del consumo incluyendo a Latinoamérica y Ecuador. Por último, se ofrece un testimonio de creación en el que confluyen lo sistmático, lo intuitivo y otros saberes.

El rol del artista en el cine independiente actual: Nomadland como ejemplo cultural del realismo capitalista
Authors: LÓPEZ DELACRUZ SANTIAGO , MARTÍNEZ NÚÑEZ EUGENIA
Published: October 2022

El arte audiovisual del siglo XXI con mayor frecuencia ha generado obras fílmicas de presupuesto limitado de gran resonancia a nivel público. Es el caso de Nomadland, dirigida en 2020 por la realizadora china Chloé Zhao, galardonada con el Oscar a la Mejor Película. El filme posee una lógica de distribución que recorrió los principales circuitos de exhibición comercial y servicios de streaming que problematiza el rol del artista en el cine independiente posmoderno. Entendiendo que la película se inscribe en una estrategia de negocio propia de un realismo capitalista, cuya finalidad es el marketing y el desentendimiento de un compromiso social efectivo, se propone como objetivo indagar, desde el contenido y la distribución de la película, de qué forma el trabajo creativo del artista se ve afectado cuando el capitalismo impone fórmulas de producción tomando a lo cultural como estrategia de mercado.

La crisis del soporte: los inicios de la objetualidad en Chile
Authors: BRUNA RODRIGO
Published: October 2022

A mediados de los años cincuenta, la pintura abstracta de carácter geométrico puso en crisis el ilusionismo pictórico replanteando los modos de producción y reflexión al interior del arte chileno. Durante los años sesenta, la abstracción geométrica se vio tensionada por el surgimiento de un tipo de abstracción, de carácter expresivo y gestual, que integró la realidad a la superficie pictórica. La influencia de estos grupos favoreció la aparición de un arte objetual que respondió al contexto político y a un afán experimental que desbordó los límites de la pintura y la escultura. A través del presente artículo, buscamos responder a la pregunta: ¿cuáles son los antecedentes que marcaron el surgimiento de la objetualidad en nuestro contexto? Mediante una metodología centrada en el análisis crítico de documentos y obras, abordamos la crisis del modelo representacional y cómo esta crisis impacta en la escena artística local renovando los discursos y la propia práctica artística.

El retorno de la artista cubana emigrada María Magdalena Campos Pons al panorama artístico de Cuba
Authors: SUÁREZ DEL VILLAR-SUÁREZ LARITZA B.
Published: October 2022

En el año 2012 aconteció en Casa de las Américas, institución insigne de Cuba, la exposición personal 1478 MB de la artista cubana residente en los Estados Unidos, María Magdalena Campos Pons. La muestra fue la primera de Magdalena en Cuba luego de emigrar hace 21 años y el hecho contundente de su reinserción en el circuito del arte de la isla. La artista cubana muestra en sus piezas la conexión con su pasado genealógico y el retorno a su terruño natal después de emigrar para enlazar su memoria y dialogar sobre la conformación de un sujeto multicultural. Su discurso se amplifica y guarda relación con su obra conocida en Cuba por la incorporación de estados introspectivos y de otros códigos propiciados por procesos vivenciales como su migración y su intercambio cultural, que de algún modo eran tratados por la artista desde una relectura de la historia de la nación cubana.

Non-Specific Medical Treatment Methods in Female Infertility
Authors: KAYA KAPLANOĞLU Dilek , TOK Abdullah
Published: October 2022

Infertility, which is defined as the inability to conceive despite one year of unprotected sexual intercourse, affects 15% of couples. Any patient with infertility by definition or at high risk of infertility may be offered an infertility evaluation. In women older than 35 years, this waiting period can be limited to 6 months, and then infertility evaluation can be started. In women older than 40 years, more urgent evaluation and initiation of treatment is the most important option. Evaluation of infertility must be done by experienced and trained physicians and necessary treatments must be followed by these physicians. Alternative treatment methods can be used in patients who do not respond after standard evaluation steps and generally accepted treatment options. Various supportive treatments come to the fore here. These options are used both to obtain better quality oocytes before treatment and to ensure that more follicles participate in stimulation. Antioxidants and metformin are the most commonly used agents before treatment in women who are thought to have insulin resistance, especially considering that oocyte mitochondrial DNA damage increases in advanced female age. On the other hand, agents such as growth hormone that should be used in a controlled manner by experienced specialists have been found effective in many publications. In the presented article, non-conventional treatment options for infertility are explained.
Body composition and level of physical activity of elderly people living in north-eastern Poland associated with socioeconomic factors
Authors: Omelan Aneta Anna , Borysławski Krzysztof , Podstawski Robert Stanisław
Published: October 2022

Introduction: Studies conducted in various regions of the world have indicated that physical activity level, body composition and socioeconomic variables can be associated. Therefore, the objective of this study was to determine whether socioeconomic factors are associated with level of physical activity and differences in the body composition of elderly people living in north-eastern Poland.
Materials and Methods: The study involved 774 older residents (60 years or more). Physical activity levels were measured with the International Physical Activity Questionnaire. The respondents’ body composition was determined with an InBody 270 analyser. Pairs of means were compared with Student’s t-test; more than two means were compared with one-way ANOVA; and proportions were compared with the chi-square test. Statistical significance was defined as p≤0.05.
Results: The marital status of men and women was significantly associated with differences in physical activity level and body composition. The place of residence and level of education of women (but not of men), were also significantly associated with differences in body composition. Age and material situation were not significantly associated with differences in body composition and physical activity level.
Conclusion: The mean values of parameters of body composition in the surveyed group exceeded the norms. The level of physical activity of the subjects is at a sufficient level, but in the case of women it depends on socio-economic characteristics. Therefore, there is a need to find effective ways to support older adults in maintaining (or increase) their physical activity with a particular focus on women.
Osteoarthritis in early modern population from Dąbrówki (Podlaskie Province)
Authors: Kątniak Anna , Podladowska Joanna , Wawrzeniuk Joanna , Tomczyk Jacek , Wyżewski Zbigniew , Myszka Anna
Published: October 2022

The aim of this analized is to evaluate the frequency of osteoarthritis in the early modern population of Dąbrówki (Poland). Evaluation of degenerative joint changes was based on standard methods commonly used in physical anthropology. Three types of changes were studied: osteophytes, porosities, and eburnations. They were analyzed in the shoulder, elbow, wrist, hip, knee, and proximal ankle joints. Osteoarthritic changes were assessed in 24 female, 20 male, and 8 undetermined sex individuals in the Dąbrówki population.
In the population from Dąbrówki the highest frequency of degenerative changes was noted in the hip joint, and the lowest in the knee joint. Osteophytes were the predominant type of lesions. The less frequent type was porosity, while polishing of the articular surfaces did not occur. In males, degenerative changes were noted more frequently than in females. Due to the existence of many interpretative limitations (there is no a complete picture of the population from Dąbrówki - skeletal material under exploration; not entirely clear and multifactorial etiology of degenerative joint changes), further analysis of the markers of environmental stress in the population from Dąbrówki is necessary.

Перманентное технологическое обновление в условиях демографического старения населения актуализирует необходимость включения новых технологий в ключевые сферы жизнедеятельности старшего поколения. Однако их возрастные и ментальные особенности, образовательные и финансовые возможности могут формировать барьеры, снижающие востребованность цифровых технологий пожилыми людьми, тем самым создавая вызовы их уровню и качеству жизни. Цель исследования − выявление зависимости между элементами технологического пространства и уровнем жизни пожилых людей. Методы исследования: анализ, синтез, регрессионный анализ. Методом регрессии на основе данных комплексного наблюдения условий жизни населения проведен эмпирический анализ влияния элементов технологического пространства на уровень жизни и экономическую активность пожилых людей. Результаты: в статье подтверждается наличие связи элементов технологического пространства и уровня жизни, отмечен положительный и отрицательный эффект во взаимосвязи с уровнем денежного дохода. Выводы: согласно полученным результатам, влияние субъективных показателей элементов технологического пространства на уровень жизни и экономическую активность пожилых людей имеет как положительный эффект, что отражает важность внедрения технологических изменений в различные сферы жизнедеятельности старшего поколения, облегчения многих рутинных операций (покупка товаров через Интернет, оплата коммунальных услуг), так и отрицательный эффект, что говорит о недостаточной вовлеченности и сложности адаптации старшего поколения к новым цифровым практикам и необходимости формирования инструментов вовлечения пожилых людей в цифровые практики.

Published: October 2022

Background: Getting pregnant and maintenance of the pregnancy in cows is crucial for the dairy farmers for sustainable production. Many methods are used for this purpose, one of them is the administration of gonadotropins at insemination and later in the early embryonic period. In this study, it was aimed to investigate the effects of different gonadotropin applications on fertility. Methods: A total of 406 dairy cows were divided randomly into five treatment groups according to GnRH (10 µg buserelin acetate, im) and hCG (1500 IU, im) administrations in different time periods at AI and post AI as; GI (n=84, d7; hCG), GII (n=106, d7; GnRH), GIII (n=62, d0 and d7; hCG), GIV (n=80, d0 and d7; GnRH), GV (n=74, d0 and d7; placebo: 2.5 ml 0.9% NaCl). Pregnancy control was done on day 30 and 45 post AI. Fertility parameters (conception rate, first service pregnancy rate, pregnancy per AI, embryonic loss) were calculated with the obtained data. Result: Our findings indicated that double dose hCG administration caused an improvement on the fertility parameters in cows with greater than 150 DIM. Also, conception rates of the cows with higher parity, milk yield and lower BCS improved with the administration of hCG on d0 and d7. We concluded that double-dose hCG administrations on d0 and d7 can be used to improve fertility after 150 DIM in cows with higher parity and milk yield.

A node selection algorithm to graph-based multi-waypoint optimization navigation and mapping
Authors: Sellers Timothy , Lei Tingjun , Luo Chaomin , Jan Gene Eu , Junfeng Ma
Published: October 2022

Autonomous robot multi-waypoint navigation and mapping have been demanded in many real-world applications found in search and rescue (SAR), environmental exploration, and disaster response. Many solutions to this issue have been discovered via graph-based methods in need of switching the robotos trajectory between the nodes and edges within the graph to create a trajectory for waypoint-to-waypoint navigation. However, studies of how waypoints are locally bridged to nodes or edges on the graphs have not been adequately undertaken. In this paper, an adjacent node selection (ANS) algorithm is developed to implement such a protocol to build up regional path from waypoints to nearest nodes or edges on the graph. We propose this node selection algorithm along with the generalized Voronoi diagram (GVD) and Improved Particle Swarm Optimization (IPSO) algorithm as well as a local navigator to solve the safety-aware concurrent graph-based multi-waypoint navigation and mapping problem. Firstly, GVD is used to form a Voronoi diagram in an obstacle populated environment to construct safety-aware routes. Secondly, the sequence of multiple waypoints is created by the IPSO algorithm to minimize the total travelling cost. Thirdly, while the robot attempts to visit multiple waypoints, it traverses along the edges of the GVD to plan a collision-free trajectory. The regional path from waypoints to the nearest nodes or edges needs to be created to join the trajectory by the proposed ANS algorithm. Finally, a sensor-based histogram local reactive navigator is adopted for moving obstacle avoidance while local maps are constructed as the robot moves. An improved -spline curve-based smooth scheme is adopted that further refines the trajectory and enables the robot to be navigated smoothly. Simulation and comparison studies validate the effectiveness and robustness of the proposed model.
Potential new applications of immunotherapy for neuroendocrine neoplasms: immune landscape, current status and future perspectives
Authors: Bai Rilan , Li Wenqian , Cui Jiuwei
Published: October 2022

Neuroendocrine neoplasms (NENs) are a highly heterogeneous class of tumors arising from neuroendocrine cells and peptidergic neurons. After failure of first-line treatment, patients have poor prognosis and limited treatment options. Immune checkpoint inhibitors (ICIs) may be a powerful means of increasing therapeutic efficacy for such patients, but ICIs alone have low response rates and short disease control durations in most NENs and may be effective for only a portion of the population. ICIs combined with other immunotherapies, targeted therapies, or cytotoxic drugs have achieved some efficacy in patients with NENs and are worthy of further exploration to assess their benefits to the population. In addition, accumulating experimental and clinical evidence supports that the interaction between neuroendocrine and immune systems is essential to maintain homeostasis, and assessment of this broad neuroendocrine-immune correlation is essential for NEN treatment. In this review, we summarize the immune microenvironment characteristics, advances in immunotherapy, predictive biomarkers of ICI efficacy for NENs, and the effects of common endocrine hormones on the immune system, highlighting possible new application areas for this promising treatment in neglected NENs.

Published: October 2022

After long years of development, the technology of analyzing the working condition of power units based on vibration signals has had relatively stable applications, but the accuracy and the degree of automation and intelligence for fault diagnosis are still inadequate due to the limitations of the current development of key technologies. With the development of big data and artificial intelligence technology, the involvement of new technologies will be an important boost to the development of this field. To support the subsequent research, bibliometrics is used as a tool to sort out the development of the technology in this field at the macro level; at the micro level, the classical and key literature is studied to grasp the development status at the technical level and prepare for the selection of entry points to continue in-depth innovation afterwards.
Anterior Hox Genes: Evolution by Birth and Death With Developmental Constraints
Authors: Marcelino Victor Montenegro , Oliveira Janaina Lima , Soares Paulo Toscano , Vieira Gustavo Calazans , Farias Savio Torres
Published: October 2022

Hox genes represent an important gene family that is involved in the segmentation pattern and identity of the segments during the formation of the body plan in metazoans. For many years, several studies have sought to establish a correlation between the evolution of these genes and the evolution of large groups of metazoans. Here, we use publicly available sequences of Hox gene clusters to reconstruct the evolutionary history of anterior Hox genes. We show that information harbored by these genes, in part, reflects the evolution and diversification of most animal archetypes, but in many cases, there were conflicts between the evolutionary history of some genes and the history of large groups, these cases may have occurred due to specific and similar selective pressures in relatively distant groups, which may have led to evolutionary convergences. Our findings also reveal that the evolution of Hox genes (and clusters) as a multigene family is consistent to a birth-and-death model constrained by development, where there is a trade-off between a relatively fast gene turnover and their central developmental roles

Facebook (FB) is the most popular online networking platform. There are several FB pages dedicated to spreading awareness about the Celiac disease (CD). To get the latest information, a huge number of CD patients follow Celiac disease Facebook (CD-FB) pages. Such pages frequently post beneficial information. However, very less is known if they provide appropriate information to CD patients. We conducted this study to know if CD-FB pages spread misleading information to CD patients. CD-FB pages from three celiac-influenced countries were explored using the FB platform and Google search engine. From October 2021 to April 2022, a total of 147 CD-FB, Italy (n=63), the USA (n=46), and India (n=38), were found eligible. Of them, 13% of pages (followers Mean±SD; Italy 2478±2011; USA 12635±12486; India 667±313) shared misleading information, particularly about gluten-free ingredients, and treatment of CD. In total,16% of CD-FB pages discussed alternative treatments option. Surprisingly, 7% of pages (followers Mean±SD; USA 23800±10465; India 628±333) supported alternative treatments for CD. CD-FB pages are useful for disseminating celiac-related information. While most of such pages provide useful information, a few pages sometimes contain misleading information. CD patients must consult their treating unit before following any uncertain information posted on CD-FB pages.

Efforts have been made to make solar cookers efficient to reduce the health risk and environmental impact of traditional cooking energy supplies used in rural areas. The solar cookers effectiveness for cooking purposes must be assessed in a specific area before installation. In essence, this paper assesses the experimental efficiency of German Scheffler, small mirror pieces, and aluminum foil based solar cookers. The solar cookers performances are evaluated at international standards by analyzing the figure of merits such as standard cooking power, sensible heating time, and exergy efficiency by using 1.7652 kg water and 1-liter oil as a heating material. The regression analysis is also performed to observe experimental data compliance with regression line. The time required to attain a water temperature of 95˚C by German Scheffler and small mirror pieces is 25 min and 1 hour with their exergy efficiency of 48.51% and 19.16% respectively, while the aluminum foil solar cooker achieves maximum water temperature of 74˚C within 2 hours and 5 minutes with 13.47% exergy efficiency. Similarly, the highest oil temperature of 275˚C is observed for the German Scheffler solar cooker. From experimental and regression results, it is revealed that German Scheffler possesses more cooking power relative to other solar cookers and their performances are highly dependent on following factors such as solar radiations, ambient temperature, environment (dust particles concentration and wind speed), radiation reflective material, aperture area, and heat losses respectively.

Rubber-based composites are widely used especially in transportation. The goal of this paper is to study the mechanical properties of rubber-based composites of carbon black and Nano Aluminum trioxide additive (50 nm). Various percentage of carbon black was used (20,40, and 60 phr). The increase in Carbon black percentage shows an increase in mechanical properties of the composites (for 60 phr properties tensile test improve by 49%, for hardness resistance the improve was 21%, and for the wear test the composite improve by 22%). Various wetting percentage of nano Aluminum trioxide was used (1,1.5,2, and 2.5 %). Increasing the wetting percentage increase tensile strength (27%, hardness resistance increase by 28%, and wear resistance increase nonlinearly with a percentage reaching 70%). Selecting the optimal composition of the two fillers, then study different irradiances for it with the ultraviolet laser of moderately low energy after the vulcanization process. Post ultraviolet laser of (345 nm). Furthermore, laser vulcanization shows improvement in mechanical properties.
Induction Generator with Direct Control and a Limited Number of Measurements on the Side of the Converter Connected to the Power Grid
Authors: Kasprowicz Andrzej , Strzelecki Ryszard
Published: October 2022

The article presents an induction generator connected to the power grid using the AC / DC / AC converter and LCL coupling filter. In the converter, both from the generator side and from the power grid side, three-level inverters were used. The algorithm realizing Pulse Width Modulation (PWM) in inverters has been simplified to the maximum. Control of the induction generator was based on the Direct Field Oriented Control (DFOC) method. At the same time, voltage control has been used for this solution. The MPPT algorithm has been extended to include the variable pitch range of the wind turbine blades. The active voltage balancing circuit has been used in the inverter DC voltage circuit. In the control system of the grid converter with an LCL filter, the number of measurements was limited to the measurement of power grid currents and voltages. Synchronization of control from the power grid side is ensured by the use of a PLL loop with the system of preliminary suppression of undesired harmonics (CDSC).

Cancer stem cells remain a challenge to isolate and characterize because of their plastic phenotype. Using a microfluidic lab-on-a-chip based on ultra-high frequency dielectophoresis, we measured the electromagnetic signature of colorectal cancer cells and demonstrated that cancer stem cells show a distinct and lower electromagnetic signature than differentiated cells. The release of extracellular vesicles from tumor cells can drive tumor progression and metastasis development. As extracellular vesicles from cancer stem cells carry more aggressive content, we treated colorectal cancer cells with these vesicles to test whether the lab-on-a-chip can detect a change in phenotype. The electromagnetic signature of treated cells is modified in comparison to untreated cells and sometimes even when no biological change is observed. The lab-on-a-chip provides rapid and relevant result without prior labeling compared to conventional biological approaches. It could be useful in the clinic for early detection of cancer stem cells in the tumor mass and for monitoring the aggressive potential of extracellular vesicles in the bloodstream in order to adapt therapeutic management and prevent relapse.
Potential of textile-dye extract as the sensitizer in dye-sensitized solar cells

A dye-sensitized solar cell (DSSC) is a device for converting photons from sunlight into electrical energy. In a DSSC, an important role is played by the dye sensitizer, which absorbs light and injects excitation electrons into the conduction band of a semiconductor oxide. As the sensitizer, complex ruthenium-based dyes provide high conversion efficiency but are expensive and scarce. As alternatives to Ru-based dyes, natural ones extracted from plants are environmentally friendly, inexpensive, and abundant. However, in DSSCs natural dyes are yet to offer higher conversion efficiency than that of complex Ru-based dyes, given low absorption in the visible range and low stability. High-purity textile dyes have been investigated as sensitizers in DSSCs, and dispersive azo dyes for textiles have been purified successfully by column chromatography, with a minimum purity of 97.3%. As such, textile-dye extract could be used as a dye in a DSSC by purifying the former using column chromatography. This article describes research on (i) DSSC fabrication and characterization, (ii) column chromatography for purifying dispersive azo dyes, (iii) the absorbance of several types of textile dye, (iv) the characteristics of the textile dye Remazol Red RB-133, and (v) the performance of a DSSC based on that dye.
Improvements to conventional methods for determining lung cancer areas from CT scan images using ImageJ - software

Published: October 2022

Early detection of lung cancer will definitely help the patients in treating the illness precisely and as early as possible.  One of the methods used to detect lung cancer is through CT scan examination. The images from CT scan will show the cancer area of lung describing the severity of lungs affected by cancer. However, the conventional method is often not accurate. Therefore, this research  aims to determine the area of cancer by segmenting the lung organs affected by cancer using Image-J software. The edge detection method was employed to segment an image. The results show that by using the proposed method, the largest cancer area is obtained in the seventh slice with the area of 15.39 cm2 and the smallest cancer area is obtained  in  the  first  slice  with  the  area  of 1.52  cm2. Whereas by using the convetional method, the  largest  cancer  area  is obtained in the fourth slice with the area of 20.57 cm2  and the smallest cancer area is  obtained  in  the  teenth  slice  with  the  area  of 3.52  cm2. The area of lung cancer in each CT Scan slice determined using ImageJ software is more accurate than the conventional method. For that reason, the  proposed  technique  is potential to improve the accuracy of a medical image analysis.

Published: October 2022

The potential users of “big data” need to consider many factors when choosing whether to use a large observational database for their research question and, if so, which database is the best fit for the scientific question. The first section of this paper, written by Dr. James A. Browne, provides a framework (who, what, where, when, and why?) to assess the critical elements that are included in a large database, which allows the user to determine if interrogation of the data is likely to answer the research question. The next section of this paper, written by Dr. Bryan Springer, focuses on the importance of having an a priori research question before deciding the best data source to answer the question; it also elaborates on the differences between administrative databases and clinical databases. The final section of the paper, written by Dr. Kurt P. Spindler, reviews the concepts of hypothesis-generating and hypothesis-testing studies and discusses in detail the differences, strengths, limitations, and appropriate uses of observational data versus randomized controlled trials.

Abstract: Electronic health records (EHRs) have created great opportunities to collect various information from clinical patient encounters. However, most EHR data are stored in unstructured form (e.g., clinical notes, surgical notes, and medication instructions), and researchers need data to be in computable form (structured) to extract meaningful relationships involving variables that can influence patient outcomes. Clinical natural language processing (NLP) is the field of extracting structured data from unstructured text documents in EHRs. Clinical text has several characteristics that mandate the use of special techniques to extract structured information from them compared with generic NLP methods. In this article, we define clinical NLP models, introduce different methods of information extraction from unstructured data using NLP, and describe the basic technical aspects of how deep learning-based NLP models work. We conclude by noting the challenges of working with clinical NLP models and summarizing the general steps needed to launch an NLP project.
Commercial Claims Data Sources: PearlDiver and Individual Payer Databases
Authors: Bolognesi Michael P. , Habermann Elizabeth B.
Published: October 2022

Individual or pooled commercial claims data sources such as the IBM MarketScan and PearlDiver provide information from health-care encounters by individuals enrolled in participating health insurance plans. These data sources contain deidentified data on demographic characteristics, enrollment start and end dates, inpatient and outpatient procedures and medical diagnoses with associated service dates and settings, and dispensed medications. Although there are concerns that long-term follow-up is limited because of interruptions in the continuity of coverage and reliance on billing data may overrecord or underrecord diagnoses and confounders, these data sources are nevertheless valuable for orthopaedic studies focusing on short-term complications, costs, and utilization.
