Reversible and Rapid Calcium Intercalation into Molybdenum Vanadium Oxides
Authors: Lakhnot Aniruddha S. , Bhimani Kevin , Mahajani Varad , Panchal Reena A. , Sharma Shyam , Koratkar Nikhil
Published: February 2022

Looming concerns regarding scarcity, high prices and safety threatens the long-term use of lithium in energy storage devices. Calcium has been explored in batteries because of its abundance and low-cost, but the larger size and higher charge density of calcium-ions relative to lithium impairs diffusion kinetics and cyclic stability. In this work, an aqueous calcium-ion battery is demonstrated using orthorhombic, trigonal and tetragonal polymorphs of molybdenum vanadium oxide (MoVO) as a host for calcium ions. Orthorhombic and trigonal MoVO outperforms the tetragonal structure because large hexagonal and heptagonal tunnels are ubiquitous in such crystals, providing facile pathways for calcium diffusion. For trigonal MoVO, a specific capacity of ~203 mAh g-1 was obtained at ~0.2C and at 100 times faster rate of ~20C, ~60 mAh g-1 capacity was achieved. The open-tunnel trigonal and orthorhombic polymorphs also promote cyclic stability and reversibility, showing a capacity fade rate of ~0.15% per cycle. A review of the literature indicates that MoVO provides one of the best performances reported to date for the storage of calcium.

Published: February 2022

Background: The aim of this study is to compare the LPP [luteal phase estradiol LPP/GnRH antagonists protocol] treatment of patients with poor ovarian response [POR] in terms of the results of in vitro fertilization [IVF] treatment who underwent LPP in the first IVF treatment or in the use of LPP in the second treatment of patients with a different protocol. Materials and methods: 293 cycles recorded in 226 patients with poor ovarian reserve who underwent LPP treatment, microdose flare-up protocols, and antagonist protocols between 2013 and 2019 were included in the study. Of these, 38 patients received LPP treatment in the first cycle and LPP treatment in the second cycle. After the microdose or antagonist protocols were applied in the first cycle, LPP treatment was applied to 29 patients in the second cycle. There were 128 patients who received LPP only once and 31 patients who received microdose flare-up only once, and these patients were included in the study based on LPP and microdose application results in the patient group with low ovarian response. Results: In our second cycle results of LPP application in patients with low ovarian response that resulted in one failed IVF, the clinical pregnancy rate was higher than the patients who received only LPP and patients who received LPP after different protocols [p=0.035]. In unsuccessful IVF patients who had LPP applied in the first cycle, β-hCG positivity per embryo and clinical pregnancy rates were found to be significantly higher in patients who received the LPP application in the second protocol [p=0.000, p=0.001].Conclusion: Repeated LPP may be the first choice protocol for low ovarian reserve patients.
Self-control and Mental Health? Exploring Perceptions of Control from the Experiences of Black and Minority Communities
Authors: Joseph Stephen , Keating Frank
Published: February 2022

Although the disparities in mental health outcomes for ethnic minorities are well-documented, very little is known regarding service user perspectives and experiences from locus of control ambit.  The aim of this qualitative study was to investigate the experiences of African and Caribbean service users, from the context of their Locus of Control (LOC). Informed by an Interpretivist approach, this study was conducted via in-depth interviews (N=10) and two focus groups (N=14). Purposive sampling methods were used to recruit mental health service users from a South London Borough to participate in the study. Data was collected through a semi-structured interview schedule and a focus group guide. Data analysis was informed by an Interpretive Phenomenology Analysis approach in the examination of the LOC profiles and service user perspectives. The study found that the drivers of LOC for the respondents were: perceived racism; perceived loss of control due to challenges pertaining to accessing employment, work stressors, lack of career advancement, socio-economic challenges; discrimination at work, identity challenges and entry to and exit pathways from mental health services, all of which promotes LOC externality. The findings suggest that mental health services need to take an active interest in factors that constitute externality in the LOC in assessment of the needs of A & C groups in clinical and community interventions. A holistic approach to psycho-social and socio-cultural issues are highly needed to improve the mental health outcomes for members of African and Caribbean communities with experience of mental health challenges.

Published: February 2022

This study aimed to get information on the cultivation of sweet pepper from the North West Region of Cameroon (Foumbot).  Data for the study were obtained from 92 farmers with the aid of well-structured questionnaires. Results obtained showed that among the sweet pepper farmers, males represented 80% of the sampled population and women 12%, all of them aged between 18 to 48 years old. Their level of education varies from primary school to University with the majority found between primary school (48%) and secondary school (30%).  41% of the sampled cultivators have the greatest level of experience in between 10 to 30 years and 52% with the lowest level of experience varying from 1 to 10 years. The sweetest pepper varieties cultivated was Yolo wonder and Simba. 89 % of respondents had a sweet pepper field with a surface area between 0.5 and 1 hectare.  According to farmers, the nursery is usually attacked by fungi after one week of growth, which always cause stems rot.  Fungicides (Mancostar 80WP) and insecticides (Mocap EC, Timik, Plantineb 80WP, Jumper and Ascot) are the most chemical products used to treat stems rot. Cypermethrin and Mancozeb represent respectively 63% and 85% of active ingredients used by the sampled growers to fight against sweet pepper diseases.  46 % of the sampled farmers said that they prefer spray pesticides in all stages while 44% of sweet pepper farmers did not take note of the number of times, they applied chemicals pesticides on their crops. NPK: 20.10.10 is the most chemical fertilizer used to grow sweet pepper. The major diseases and pests encountered in that region are (1) diseases: Mildew, cercospora leaf spot, phytophthora blight, fusarium wilt, anthracnose, ripe rot, tobacco mosaic virus, cucumber mosaic virus, and gal formations; (2) pests: flee beetles, cutworms, aphids, vegetable weevil, caterpillars, grasshoppers, pepper maggots and leaf miners.

The effect of chitosan nanoparticles on Escherichia coli viability in drinking water disinfection
Authors: Denisova V. , Mezule L. , Juhna T.
Published: February 2022

Drinking water disinfection or inactivation of pathogenic microorganisms is an essential step to minimize infection risks and decrease the incidence of waterborne diseases. Recently, chitosan nanoparticles (CNs) have been highlighted as an antimicrobial agent for a wide range of applications due to their natural antimicrobial properties, and low or no toxicity risk for human health. In this study, we generated CNs from three different molecular weight (MW) chitosan (low, medium, high) at various concentrations (0.25, 0.5 and 2% (w/v)). After the CNs preparation and quality assessment, the antimicrobial activity was evaluated by measuring the log reduction of Gram-negative bacteria E. coli as a model microorganism for faecal pollution. The results demonstrated that 0.25% of medium MW CNs are optimal for more than 99.99% reduction of cultivable E. coli and 97% inactivation of metabolically active E. coli. These results indicated that CNs were able to inhibit the growth of cultivable and metabolically active E. coli in tap water and demonstrated the potential use of CNs as an alternative antimicrobial agent in drinking water disinfection.
An integrated fuzzy optimization and simulation method for optimal quality-quantity operation of a reservoir-river system
Authors: Babamiri Omid , Azari Arash , Marofi Safar
Published: February 2022

In this study, a novel optimization-simulation dynamic approach was developed for optimal water operation of reservoir-river systems to improve the water quality and supply the water demands along a river. To this purpose, the WEAP-QUAL2 K linked model was developed to simulate water quality and quantity, which is dynamically coupled to a fuzzy multi-objective imperialist competition algorithm (FMOICA). The approach's applicability is demonstrated through the case study of the Dez reservoir river in Iran. The simulation and optimization period used was six years (October 2019-September 2025). Stochastic models (SARIMA(1,0,1)(1,1,1)) were used to forecast inflow into the Dez dam reservoir for the simulation period. Given that in the verification stage of the QUAL2 K and WEAP model it was concluded that the model has high accuracy in simulating the parameters of water quality and quantity, two scenarios were considered: the first scenario was used for dynamic coupling of the quantity-quality model (reference scenario), and the second was the fuzzy optimization of a linked model (optimal scenario). The results show that average water supply reliability increased from 86.13% in the reference scenario to 95.76% in the optimal scenario. Also, under the optimal scenario, the river water quality improves. It was also found that environmental flow rate demands of the river are fully supplied in different months.

Analyzing Association Between Expression Quantitative Trait and CNV
for Breast Cancer Based on Gene Interaction Network Clustering and
Group Sparse Learning
Authors: Chen Xia , Lin Yexiong , Qu Qiang , Ning Bin , Chen Haowen , Liao Bo , Li Xiong
Published: February 2022

Aims:

Aims: The occurrence and development of tumor is accompanied by the change of pathogenic gene expression. Tumor cells avoid the damage of immune cells by regulating the expression of immune related genes.

Background:

Background: Tracing the causes of gene expression variation is helpful to understand tumor evolution and metastasis.

Objective:

Objective: Current gene expression variation explanation methods are confronted with several main challenges: low explanation power, insufficient prediction accuracy, and lack of biological meaning.

Method:

Method: In this study, we propose a novel method to analyze the mRNA expression variations of breast cancers risk genes. Firstly, we collected some high-confidence risk genes related to breast cancer and then designed a rank-based method to preprocess the breast cancers copy number variation (CNV) and mRNA data. Secondly, to elevate the biological meaning and narrow down the combinatorial space, we introduced a prior gene interaction network and applied a network clustering algorithm to generate high density subnetworks. Lastly, to describe the interlinked structure within and between subnetworks and target genes mRNA expression, we proposed a group sparse learning model to identify CNVs for pathogenic genes expression variations.

Result:

Result: The performance of the proposed method is evaluated by both significantly improved predication accuracy and biological meaning of pathway enrichment analysis.

Conclusion:

Conclusion: The experimental results show that our method has practical significance

Published: February 2022

Background:

Specific Antibody Deficiency (SAD) is a primary immunodefi-ciency disease (PID) characterized by the occurrence of recurrent infections and inade-quate antibody response to polysaccharide new antigens.

Objective:

This study aims to determine the titer of specific antibodies against unconju-gated 23-valent pneumococcal polysaccharide vaccine (PPSV-23), the presence of SAD, and its association with clinical and laboratory findings in Ataxia-telangiectasia (A-T) and selective immunoglobulin A deficiency (SIgAD) patients.

Methods:

32 A-T patients and 43 SIgAD patients were included in this cross-sectional study. Samples of the patients were obtained before and three weeks after vaccination with PPSV-23. Specific immunoglobulin G (IgG) directed towards pneumococcal capsular an-tigen and specific antibodies against whole pneumococcal antigens was measured.

Results:

Comparison of the response to vaccination revealed that 81.3% of A-T patients and 18.6% of the SIgAD patients had an inadequate response to PPSV-23 (p<0.001). The prevalence of recurrent infection (p=0.034) and pneumonia (p=0.003) in SIgAD patients was significantly higher in non-responders than responders. Likewise, the number of mar-ginal zone B cells (p=0.037), transitional B cells (p=0.019), plasmablasts (p=0.019), CD8+ naïve T cells (p=0.036), and percentage of CD8+ T cells (p=0.047), switched memory B cells (SMB) (p=0.026) and immunoglobulin M (IgM) memory B cells (p=0.022) in SIgAD patients were significantly lower in non-responder group than responder group. In con-trast, the percentage of CD4 T+ cells in A-T patients was lower in the non-responder group than responders (p=0.035).

Conclusion:

SAD is more frequent in A-T patients than SIgAD patients. The role of SMB and T cells should not be underestimated in SAD.
An Integrated, Multimodal, Digital Health Solution for Chronic Obstructive Pulmonary Disease: Prospective Observational Pilot Study
Authors: Gelbman Brian D , Reed Carol R
Published: February 2022

Background

Chronic obstructive pulmonary disease (COPD) affects millions of Americans and has a high economic impact partially due to frequent emergency room visits and hospitalizations. Advances in digital health have made it possible to collect data remotely from multiple devices to assist in managing chronic diseases such as COPD.

Objective

In this pilot study, we evaluated the ability of patients with COPD to use the Wellinks mHealth platform to collect information from multiple modalities important to the management of COPD. We also assessed patient satisfaction and engagement with the platform.

Methods

A single-site, observational, prospective pilot study (N=19) was conducted using the Wellinks platform in adults with COPD. All patients were aged over 30 years at screening, owned an iPhone, and were currently undergoing a treatment regimen that included nebulized therapy. Enrolled patients received a study kit consisting of the Flyp nebulizer, Smart One spirometer, the Nonin pulse oximeter, plus the Wellinks mHealth app, and training for all devices. For 8 weeks, participants were to enter daily symptoms and medication use manually; spirometry, nebulizer, and pulse oximeter data were automatically recorded. Data were sent to the attending physician in a monthly report. Patient satisfaction was measured via a 5-point scale and the Net Promoter Score (NPS) captured in interviews at the end of the observation period.

Results

Average age of the patients was 79.6 (range 65-95) years. Participants (10 female; 9 male) had an average FEV1% (forced expiratory volume in 1 second as % of predicted for the patient) of 56.2% of predicted (range 23%-113%) and FEV1/forced vital capacity of 65%. COPD severity, as assessed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, was mild in 2 patients, moderate in 6, and severe/very severe in 11; 9 patients were on home oxygen. During this 8-week study, average use of the spirometer was 2.5 times/week, and the pulse oximeter 4.2 times/week. Medication use was manually documented 9.0 times/week, nebulizer use 1.9 times/week, and symptoms recorded 1.2 times/week on average. The correlation coefficients of home to office measurements for peak flow and FEV1 were high (r=0.94 and 0.96, respectively). Patients found the app valuable (13/16, 81%) and easy to use (15/16, 94%). The NPS was 59.

Conclusions

This study demonstrates that our cohort of patients with COPD engaged with the Wellinks mHealth platform avidly and consistently over the 8-week period, and that patient satisfaction was high, as indicated by the satisfaction survey and the NPS of 59. In this small, selected sample, patients were both willing to use the technology and capable of doing so successfully regardless of disease severity, age, or gender. The Wellinks mHealth platform was considered useful and valuable by patients, and can assist clinicians in improved, timely decision making for better COPD management.
Teledermatology and Artificial Intelligence
Authors: Navarrete-Dechent Cristian
Published: February 2022

Background

The use of artificial intelligence (AI) algorithms for the diagnosis of skin diseases has shown promise in experimental settings but has not yet been tested in real-life conditions. The COVID-19 pandemic led to a worldwide disruption of health systems, increasing the use of telemedicine. There is an opportunity to include AI algorithms in the teledermatology workflow.

Objective

The aim of this study is to test the performance of and physicians’ preferences regarding an AI algorithm during the evaluation of patients via teledermatology.

Methods

We performed a prospective study in 340 cases from 281 patients using patient-taken photos during teledermatology encounters. The photos were evaluated by an AI algorithm and the diagnosis was compared with the clinician’s diagnosis. Physicians also reported whether the AI algorithm was useful or not.

Results

The balanced (in-distribution) top-1 accuracy of the algorithm (47.6%) was comparable to the dermatologists (49.7%) and residents (47.7%) but superior to the general practitioners (39.7%; P=.049). Exposure to the AI algorithm results was considered useful in 11.8% of visits (n=40) and the teledermatologist correctly modified the real-time diagnosis in 0.6% (n=2) of cases. Algorithm performance was associated with patient skin type and image quality.

Conclusions

AI algorithms appear to be a promising tool in the triage and evaluation of lesions in patient-taken photographs via telemedicine.

Las pinturas murales del convento franciscano de San Gabriel, Cholula
Authors: Fernández Flores Ligia
Published: February 2022

Uno de los temas que mayor interés ha suscitado entre los especialistas del arte virreinal en México, es el relacionado con la pintura mural del siglo XVI debido a que en dicha manifestación artística —entre otros aspectos— se puede estudiar y reflexionar en torno a la forma en que posiblemente los indígenas pudieron asimilar las formas y técnicas artísticas procedentes del mundo europeo. Por ello, el objeto de este trabajo es realizar un breve acercamiento artístico a algunas de las pinturas murales que aún se conservan en el claustro del convento franciscano de San Gabriel en Cholula, ciudad localizada en el actual estado de Puebla, ya que fue uno de los conjuntos conventuales más importantes durante dicha centuria en la zona Puebla-Tlaxcala.
La narrativa de Rosario Castellanos
Authors: Spada Suárez Rosa
Published: February 2022

Rosario Castellanos (1925-1974) es una de las primeras mujeres mexicanas reconocida como escritora profesional. Esto quiere decir que es la primera en dedicar su tiempo y su interés a la literatura como oficio, y en comprometerse con esta tarea como actividad central de su vida. Así lo demuestran la consistencia de su obra y su ejercicio docente. Ella misma fue muy consciente de su elección, así se lo comentó a Emmanuel Carballo: “Desde mis primeros textos quise vivir profesionalmente como escritora. La poesía es algo en lo que no se puede fiar [...] Necesitaba llenar el resto del tiempo con una disciplina constante y que dependiera de mi voluntad. Esta disciplina sólo podría lograrla a través de la prosa”.

La narrativa de Rosario Castellanos puede caracterizarse por dos discursos: el feminista y el indigenista.

En México, y en especial, en la ciudad de México, la mujer venía luchando por manifestarse más activamente en la sociedad; entre 1940 y 1950 comienzan a publicar algunas mujeres cuyos libros llegaron a tener gran difusión como Emma Godoy, Margarita Michelena y la propia Rosario Castellanos. Por entonces, también, se hace más abierta la reflexión sobre el tema de la “condición femenina”, y se desarrolla con más fuerza un discurso femenino y feminista. De esto es ejemplo la misma Rosario Castellanos con su primera obra ensayística titulada Sobre cultura femenina 1950.3

Es conveniente apuntar, aunque sea de manera muy general, algunas de las características del contexto literario mexicano en el cual se inscribe la producción de Cas-tellanos. Durante el periodo de 1948 a 1974, el desarrollo de la narrativa mexicana asume la superación o neutralización de la novela de la Revolución mexicana en función de la consolidación del Estado burgués emanado de la misma Revolución. El crecimiento y el desarrollo de la ciudad de México determinan el nacimiento de la novela propiamente urbana y el interés por la indagación subjetiva típica de esta modalidad. Se modernizan las técnicas y la atención se desplaza de lo local, social e indígena, a lo urbano, individual y mestizo. Aparece, además, la literatura de la “onda”, la novela del lenguaje y otras manifestaciones. Castellanos pertenece a la generación de narradores del cincuenta. Asi mismo en Oficio de tinieblas asistimos a la auscultación literaria de lo nacional, lo que corresponde a ciertas tendencias de la época, pero Castellanos no la hace desde una perspectiva filosófica, antropológica o mítica de corte estático y metafísico, sino desde una visión dinámica del tipo histórica y social.
Conocer la Catedral de Sal es una mina de cultura colombiana
Authors: Spada Rosa
Published: February 2022

Los profesores de español, de arte, de literatura y de historia para extranjeros en la ciudad de Bogotá, Colombia organizan dos veces al mes visitas a lugares turísticos que forman parte del patrimonio cultural de ese país. Ejemplo de ello fue la visita a la catedral de Sal en Zipaquirá. Tan sólo a 50 kilómetros al norte de la capital de Colombia, a unos 45 minutos (por auto) y casi dos horas por tren, se localiza el municipio de Zipaquirá, a una altura de 2 750 metros en la Cordillera Oriental de los Andes. En ese lugar se encuentra el Cerro del Zipa, que forma parte de las minas de sal dentro de las cuales se construyó la Catedral, una magnífica obra de arte e ingeniería, bajo la tierra, en las salinas.

La Catedral está dedicada a la Virgen del Rosario, que los indígenas llamaban: “Nuestra Señora de Guasá”. En sus socavones se concibieron espacios para las 14 estaciones del Vía Crucis, una bellísima cruz de grandes proporciones tallada en bajorrelieve, cuya iluminación produce una apacible ilusión óptica, capillas y estancias sacramentales en un ambiente de sombras y penumbra que nos transmiten paz y armonía sublimes.

Zipaquirá es un lugar sagrado de sal. Su nombre deriva de la palabra en lengua indígena chicaquicha que significa al “pie del suegro o yerno” y de la palabra chipaquicha al “pie de nuestro padre”; Zipaquirá, —que hasta antes del siglo pasado se escribía Cipaquirá— significa “Ciudad o poblado de nuestro Padre”, era el sitio donde habitaban los indígenas muiscas a los pies del Cerro de Zipa.

Las salinas de Zipaquirá tienen una existencia milenaria y fueron explotadas por los muiscas, que además del uso práctico, hicieron de la sal su principal instrumento de intercambio, equivalía a su moneda. Por ese motivo, la sal, fue causa de varios conflictos entre los muiscas quienes trataban de ejercer dominio absoluto sobre ese preciado bien.

Un acercamiento al estudio de las creencias de los profesores de lengua extranjera
Authors: Pizarro Carmona Mercedes
Published: February 2022

En los últimos 25 años, la didáctica de lenguas ha experimentado una importante evolución. Concretamente, el desarrollo de los estudios sobre la cognición ha permitido explorar las concepciones de los profesores acerca de la enseñanza y aprendizaje de una lengua extranjera (LE) y ha revelado que las creencias ejercen gran influencia en las decisiones que se toman en clase. Toda elección sobre qué y cómo enseñar, refleja las creencias del profesor sobre lo que piensa del proceso de enseñanza y aprendizaje de una lengua y ello influye en su actitud en el aula. Tomar conciencia sobre los pensamientos del profesor acerca de lo que cree eficaz en el proceso de enseñanza-aprendizaje de una lengua extranjera es un paso previo y fundamental para mejorar la labor docente.

Published: February 2022

A la pregunta: “Del curso de español, cuáles han sido las actividades que más te han gustado”” la respuesta más general fue: “Aquellas en las que podíamos trabajar en equipo y hablar de nuestros países”.

¿A qué actividades se refieren los estudiantes? ¿Qué puntos gramaticales se enfocan en ellas? ¿Qué procedimientos se siguen en su desarrollo? ¿Qué plantea la actividad para establecer lazos entre culturas distintas? ¿Qué concepto de interculturalidad subyace en las actividades?

Daremos aquí una respuesta a estas preguntas y propondremos algunas actividades en la que se unan la gramática y la interculturalidad.

Presentaremos primero lo que para nosotr@s significa interculturalidad y cómo la relacionamos con la gramática en las actividades que diseñamos para la enseñanza y el aprendizaje del español.

Al mismo tiempo, iremos presentando actividades en las que hemos procurado desarrollar en forma conjunta ambas competencias; esperamos que esto contribuya a la reflexión sobre este tema y a que nuestr@s lector@s elaboren o reelaboren algunas propuestas de actividades que podrían ser pertinentes para su quehacer docente.
PROBLEMATIKA PENGATURAN DAN PENERAPAN SANKSI PIDANA ATAS PELANGGARAN PASAL 15 UNDANG-UNDANG NOMOR 24 TAHUN 2011 TENTANG BADAN PENYELENGGARA JAMINAN SOSIAL
Authors: Khakim Abdul
Published: February 2022

The purpose of this paper analyzes the differences in sanctions regulation for violations of Article 15 and Article 19 of Law No. 24 of 2011 on Social Security Administering Body (Law 24/2011), which is a violation of Article 15 of Law 24/2011 subject to administrative sanctions (based on Article 5 PP 86/2013), while violations of Article 19 paragraph (1) and (2) of Law 24/2011 are subject to criminal sanctions (based on Article 55 of Law 24/2011). This study used normative juridical research methods. The results of this study show that there is a gap in the regulation and application of sanctions between Article 15 and Article 19 of Law 24/2011, whereas substantive violations of both articles are the same, because employers do not register themselves and their workers as participants to the Social Security Administering Body (BPJS). In fact, it aims to avoid the collection and payment of dues of participants who are responsible to BPJS. It should be a violation of Article 15 of Law 24/2011 not subject to administrative sanctions, but criminal sanctions article 55 of Law 24/2011 as well as Article 19 paragraph (1) and (2) Law 24/2011. The problem is constrained by the principle of legality in criminal law and depends on the ‘Courage’ of the judge to make a legal discovery. Conclusions obtained in the study are: (a) open possibility of application of criminal sanctions (ultimum remedium)against violations of Article 15 of Law 24/2011; (b) the occurrence of dissent against the possible application of criminal sanctions for violations of Article 15 of Law 24/2011 due to the separation of sanctions arrangements; (c) Employees of The Manpower Supervisory (PPK) must be observant and committed in law enforcement, especially against violations of Article 15 of Law 24/2011; and (d) on the issue of differences in sanctions it needs a deep understanding and built comprehensive legal construction as well as the need for legal discovery by judges.

The authors analyze and systematize multi-temporal cartographic material, as well as information on the history of Buinsk city territory development in determining the historic boundaries of settlements. For this, information is presented on the formation of the uezd town of Buinsk on the basis of Buinskoye village in the Simbirsk gubernia in the 18th century and the transformation of its borders during the 19th century. The authors present an overview of historical cartographic sources, the results of analyzing scientific historical and cultural (historical and architectural, historical and urban planning, historical and archival, archaeological) materials, information obtained arising from viewing the ancient buildings of the historical settlement, containing information on the city of Buinsk. Cartographic overlay and spatial referencing of historical and modern materials were carried out, taking into account the location of cultural heritage objects included in the unified state register (historical and cultural monuments) of the Russian Federation’s peoples, identified cultural heritage features and historically valuable cityforming ones. In addition, the results of analyzing compositional-and-species relationships of the historic settlement were taken into account. In this article, for the first time, cartographic sources on the history of Buinsk city are collected and summarized. Our studies served as the basis for defining the boundaries of the regional significance historical settlement territory, as well as identifying the elements of the regional significance historic settlement subject protection – “City of Buinsk”. As a result, the objects of cultural heritage and the subject of protection of the historical settlement were identified; the requirements for the regimes of maintaining the territory and town planning regulations were determined for them.
Algumas considerações acerca do anacronismo na história da arte
Authors: Gonçalves Rosa Gabriella
Published: February 2022

O objetivo deste artigo é o de refletir acerca da estratégia do anacronismo no âmbito das artes visuais, o qual entendemos como sendo a aproximação entre objetos produzidos por diferentes culturas, como uma montagem na qual não são considerados sua origem ou finalidade. Tal forma de apresentação, recorrente em exposições na contemporaneidade, remonta às exposições e publicações concebidas pelas vanguardas históricas, com a expectativa de por meio de uma espécie de choque, revelar novos significados e objetos de conhecimento, mas por outro lado, tais aproximações correm o risco de serem apenas atraentes, sem contribuir para uma compreensão aprofundada da diversidade cultural.

El propósito de esta investigación consistió en exponer la creación de un indicador ponderado para evaluar el desarrollo económico que fuera más representativo y acorde con las condiciones de México. En el índice propuesto se consideran dos aspectos clave en su configuración: el aspecto subjetivo, el cual es definido a través de una encuesta aplicada a un grupo de expertos temáticos; y el aspecto objetivo, evaluado a partir de variables cuantitativas. El índice, en su aspecto subjetivo, contó con validación estadística realizada mediante el análisis de factores, y la validez de contenido, que se obtuvo con base en la opinión de personas expertas relacionados con el área de estudio. El índice propuesto tuvo una importante aportación en torno a la medición del desarrollo económico y su relación teórica con el desarrollo social del país. Con la aplicación de este indicador, y sus resultados obtenidos, se espera que funja como una herramienta complementaria en la medición del desarrollo económico, e incluso, que pueda ser de apoyo en la definición de problemas con la posibilidad de ser resueltos mediante la implementación de políticas públicas.

Authors: Daza-Hernández Leonar Ernesto , Montoya-Quintero Diana María
Published: February 2022

La Contraloría General de Medellín, en el ejercicio del control a los recursos públicos que gestiona el municipio y particulares, requiere que en las auditorías fiscales se refleje el conocimiento organizacional como producto de los conocimientos personales de quienes participan en las decisiones y no un conocimiento personalizado que pueda llevar a diferentes interpretaciones o decisiones opuestas en el análisis, valoración y validación de observaciones y/o hallazgos; para ello, se diseñó un modelo de Gestión del Conocimiento para las auditorías fiscales que realiza la entidad, a fin de fortalecer las competencias funcionales y el conocimiento organizacional. Se revisó documentos y bibliografía para identificar, comparar y seleccionar modelos y/o teorías generales cercanas a la problemática, se identificaron elementos organizacionales, contextuales y de proceso necesarios para la construcción del modelo y se elaboró el mapa de conocimientos. El estudio fue de tipo descriptivo, se aplicó observación directa, entrevistas y cuestionarios como herramientas de recolección de datos. Mediante metodología mixta se identificaron conceptos y variables relacionadas con las capacidades dinámicas del proceso auditor. El resultado fue un modelo de Gestión del Conocimiento para las auditorías de control fiscal realizadas por la Contraloría General de Medellín; entidad en la que fue socializado y validado, allí se resaltó su importancia y los resultados obtenidos, entre ellos, la necesidad de la entidad por gerenciar en debida forma el conocimiento del talento humano para fortalecer el área misional, el formato y el procedimiento de lecciones aprendidas, los resultados de las brechas de necesidades y las iniciativas estratégicas propuestas para conservar y transferir de manera eficiente y sistemática el conocimiento para fortalecer las competencias funcionales de los auditores y el conocimiento organizacional.

Continuous measurement of temperature profiles on the human body surface provides handy information for the diagnosis and as a beneficial guide to take appropriate action. A textile based Resistance Temperature Detector (RTD) has been reported recently, which could be exploited to monitor the temperature of human body over extended period of time. For the purpose of calibrating these textile based sensor, a tailor-made test rig has been developed. The working principle of this sensing fabric is the same as the RTD i.e. change in resistance because of change in temperature. Validation of experimental results by modelling was one of the prime objectives of this study. This paper reports the steady state mathematical model of the test rig components, by the application of fundamental heat transfer principles. It was concluded that the temperature varies linearly across the thickness of textile based temperature sensor in a rig setting while the temperature of the sensing element of textile based temperature sensor could be approximated by knowing its exact position within the fibrous structure. This input would be helpful for the calibration purpose of the sensor samples in an improved manner and to circumvent the individual testing and repetition of experiments on a test rig.

An experiment was conducted at Experimental Farm, College of Horticulture and Forestry, Neri, Hamirpur during May 2019 to October, 2019 cropping season to study the effect of different sowing dates viz., 17th May (1st), 7th June (2nd), 27 June (3rd) and 17th July (4th) on the development of bacterial leaf spot of bottle gourd and pumpkin caused by Xanthomonas cucurbitae. It was observed that the mean disease severity in both bottle gourd and pumpkin crops decreased with delay in the date of sowing from mid May (40.15 and 31.73%, respectively) to the end of June (27th June, 31.65 and 27.06%, respectively) or mid July (17th July, 23.32 and 20.13%, respectively). The disease incidence was also found to be minimum in the fourth (31.31%) and third (39.60%) dates of sowing in case of bottle gourd fruits and no incidence of the bacterial spot was recorded in case of pumpkin fruits. In the case of bottle gourd, the expected yield loss was minimum in crops sown mid July (31.44%) while in pumpkin, the fruit yield was more in mid July (9.59 kg vine-1) sown crop in comparison to mid May and early June sown crops. So, it was concluded that late June and mid July sown crops of both bottle gourd and pumpkin are less vulnerable to the disease leading to reduced crop losses and higher yield.
