On Water Circulation in the Valley Reservoir (Krasnodar Reservoir)
Authors: Pogorelov Anatoly V. , Laguta Andrey A.
Published: January 2021

The Krasnodar reservoir has undergone significant transformations during its operation since 1973. As a result of active delta formation of the Kuban and Belaya rivers, the reservoir was divided into two autonomous reservoirs, its area decreased by 35 %. To understand the mechanisms of transformation and the processes of siltation of the reservoir, it is necessary to establish the features of the dynamics of water masses. Based on the results of the ADCP survey carried out in July-August, 2016, the circulation of water masses in the reservoir was analyzed. The distance between survey lines during the survey was 100 m with a total length of 2518 km, the frequency of measurements was 0.28 m-1. The resulting array of data on the velocity vectors (18.6 million values) in combination with the resulting digital model of the reservoir basin was processed in GIS using geostatistical analysis tools. It has been established that the general dynamics of water masses is characterized by cyclonic circulation with a pronounced western runoff current along the right bank of the reservoir. The prevailing velocities of currents are 0.02 ... 0.05 m/s. With steady westerly winds, a shift of the main water jet to the south into the interior of the reservoir was recorded. In the vertical movement of water masses, ubiquitous downward currents were noted in the eastern part of the reservoir, caused by the influx of colder river waters.

A carência de conhecimento no que diz respeito ao ciclo da araruta, pode acarretar em prejuízos na produção, pois a colheita antecipada pode ocasionar perdas por não atingir o nível máximo de acúmulo de matéria seca nos rizomas e a colheita tardia aumenta o índice de podridão dos rizomas, diminuindo a qualidade do mesmo. Objetivou-se com este trabalho, determinar o efeito da época de colheita na produtividade e na qualidade química de amido de araruta. Foram utilizados rizomas de araruta, colhidos em cinco épocas diferentes (253, 273, 295, 314 e 336 dias após o plantio). No campo o experimento foi instalado em setembro de 2016 a agosto de 2017 no município de Lavras-MG em delineamento em blocos casualizados, com três repetições. No laboratório os experimentos foram realizados em delineamento inteiramente casualizados com três repetições, foi avaliado o rendimento da extração, composição centesimal, quantidade de amido purificado e análise de microscopia eletrônica. Os efeitos quantitativos foram ajustados a um modelo de regressão. Foi realizada análise de múltiplos fatores e análise fatorial. A época de colheita da araruta interfere nas características agronômicas de produtividade de rizomas, fécula e na composição química da fécula de araruta. A colheita da araruta variedade seta aos 336 dias após o plantio foi o mais propício, por apresentar maior produtividade de rizomas (61,31 Mg ha-1) e fécula (15,25 Mg ha-1) por área, além de apresentar maior pureza na fécula (99,02%) e menor teor de fibra (0,36%).

Published: January 2021

O desmatamento é um dos principais fatores de degradação do meio ambiente, apesar de haver uma Lei específica para a proteção de Área de Preservação Permanente (APP) e Reserva Legal (RL) ainda é difícil para o produtor/proprietário rural compreender a importância de seguir a legislação ambiental. Diante disto, o presente trabalho teve como objetivo avaliar o que 50 agricultores familiares das comunidades rurais do município de Ribeira Ambiental compreendem em relação à legislação ambiental, realizando um diagnóstico a partir de questionários referente à APP e RL. Os dados foram coletados e manipulados no Excel 2010, e transformados em gráficos através de percentuais de maneira qualitativa e quantitativa. Os resultados mostraram que os agricultores possuem pouca informação sobre as áreas de conservação, APP e RL, pois quando questionados sobre o conceito e a importância, a maioria 60% não souberam responder. Constatou-se pouco conhecimento sobre legislação ambiental em relação as áreas protegidas na agricultura familiar no semiárido da Bahia, o que de fato pode ocasionar danos ambientais.

Published: January 2021

A propagação sexuada do araticum apresenta alguns fatores limitantes causados pela dormência das suas sementes. Assim, tornam-se necessárias pesquisas que envolvam diferentes técnicas de propagá-lo. Diante do exposto, objetivou-se estimar o efeito de diferentes doses de ácido indolbutírico (AIB), tipos de estacas e substratos no enraizamento adventício de araticum. Foram realizados seis ensaios avaliando os fatores: época de coleta; doses de ácido indolbutírico; substratos; e estacas de diferentes consistências, tamanho, e quantidade de folhas. Nos experimentos com estacas sobreviventes avaliaram-se o número de folhas e brotos por estaca; porcentagem de estacas vivas; estacas com calo; estacas enraizadas; comprimento do sistema radicular; número de raízes por estacas; e massa de matéria fresca e seca do sistema radicular. No araticum a época do ano constitui-se como um dos principais fatores que interferem na porcentagem de estacas vivas, com calos, e enraizadas; e a consistência semilenhosa das estacas são mais viáveis para a sua propagação pelo método de estaquia.

Published: January 2021

Os indicadores são substâncias indigestíveis, geralmente de fácil determinação, muito utilizados para estimar a produção fecal em animais através de amostras fecais, dispensando coleta total de fezes. Os indicadores são bastante estudados em ovinos e bovinos, porém estudos em bubalinos são escassos, dessa forma objetivou-se avaliar a eficácia dos indicadores LIPE®, Óxido de Cromo III (Cr2O3) e Óxido de Titânio (TiO2) para estimar a produção fecal em búfalos. Utilizou-se 18 búfalos (Bubalus bubalis) machos, Murrah, com peso vivo médio de 150 kg. Uma vez ao dia a mensuração da excreção fecal foi realizada através da coleta total de fezes e estimada por indicadores externos LIPE®, Cr2O3 e TiO2. As estimativas de produção fecal com indicadores Cr2O3 e o LIPE® não diferiram da produção fecal determinada pela coleta total, porém não houve correlação com a coleta total. A estimativa de produção fecal realizado pelo TiO2 superestimou a produção total de fezes, porem houve correlação positiva com a coleta total de fezes, podendo ser corrigido a seguinte equação: Excreção fecal (Kg.d-1) = 0.17*Excreção fecal estimada pelo TiO2 (Kg.d-1) + 2.0671.

Objectives: We aim was to evaluate the quality and reliability of the information on knee arthroplasty available on YouTube in Turkish.
Methods: A systematic search was conducted using the term “diz protezi” (knee prosthesis) on 1 June 2020.Videos were filtered based on their degree of relevance alone. Videos that were not in Turkish, not on knee prosthesis or without audio and/or image were excluded. Copied videos were evaluated as a single video. The first 50 videos that came up in the search were included in the study. Video quality was scored using Global Quality Score (GQS). To assess reliability, modified DISCERN scale was used.
Results: The mean view count per video was 31.533 ± 100.921 and the total view count was 1.576.633. The mean duration per video was 337 ± 475 seconds. The median number of likes per video was 13 (0-426). The median number of dislikes per video was 2.5 (0-83). The mean GQS of the videos was 3.25 ± 0.9. When the reliability of the sources was evaluated using DISCERN, the mean score of the videos was 2.18 ± 1.2. It is striking that all videos were prepared by an orthopedic surgeon. Of the medical doctors preparing the resources, 44% had academic titles.
Conclusions: It was found that Turkish resources on arthroplasty on YouTube are promising in terms of quality. Content creators must make effort to increase their reliability according to DISCERN.

Authors: Hernández Horacio ANTONIO
Published: January 2021

El objetivo del presente fue determinar si el practicar el periodo seco en cabras bajo condiciones de pastoreo incrementa la producción láctea y la cantidad de los componentes químicos de la leche. En el grupo de cabras sin periodo seco los animales se mantuvieron diariamente en ordeño manual hasta la ocurrencia del parto (SPS; n = 9). En las cabras del grupo con periodo seco se practicó el secado al suspender el ordeño manual desde 50 días antes del parto (CPS; n = 11). Se utilizó un diseño factorial con un modelo lineal de efectos fijos para evaluar la producción de leche y la cantidad de sus componentes en respuesta al tratamiento, el factor tiempo y la interacción tiempo×tratamiento. Existió un efecto del tratamiento sobre la producción de leche durante la lactancia, por lo que ésta fue mayor para el grupo CPS que para el grupo SPS (P<0.001). De igual manera la cantidad de componentes de la leche mostró un efecto significativo del tratamiento (P<0.001). Se concluye que en cabras lactantes mantenidas en condiciones de pastoreo el practicar el periodo seco promueve una mayor producción de leche en la subsiguiente lactancia y por ello también una mayor cantidad de sus contenidos.

Published: January 2021

Background: Practicing the unsustainable system of farming contributes in no small way to soil deterioration which in turn affects agricultural productivity. Even though one of the important requirements for embracing any agrarian practice is the financial viability of the process, it is believed that the differences in the benefits obtained from both conventional farming and conservation agriculture are not well articulated. While general inference can be made, it is also important to make a thorough evaluation of the benefits that can be derived from conservation agriculture and conventional agriculture. Methods: The study was conducted in Okhahlamba Local Municipality, which is situated in-between Lesotho, Free State Province, Alfred Duma and the Inkosi Langalibalele Local Municipality. Secondary data were retrieved from the Mahlathini Organics dataset collected from three different seasons, such as 2012/2013 to 2014/2015 and 2016/2017 seasons. The farmers under study practiced conservation agriculture (0.8ha) and conventional agriculture (0.8ha). Result: Using Gross Margin in addition to indicators like Benefit-Cost Ratio, Internal Rate of Returns and Net Present Value, this research identified that the advantages of using the conservation system of farming are enormous when matched with conventional agriculture. Consequently, this research suggests the advancement and encouragement of conservation agriculture as it provides more incentives in the long run.

Authors: Rajput Manmohan Singh , Kamboj M.L. , Kumar Nishant
Published: January 2021

Background: Energy is the major nutrient needed for dairy cattle and its insufficient intake has a detrimental effect on their reproductive activity. Methods: The aim of this study was to investigate the effect of biostimulation on behaviour and energy balance of Sahiwal cows during peri-estrus through 2 types of bull contact. For this, 24 postpartum cows were divided into 3 similar groups (T0, T1 and T2) of 8 cows each. In T0, cows were not exposed to bull; in T1 the cows were exposed to bull through a fence-line contact and in T2, the cows were in direct bull contact for 12 hours daily. Result: In first post-partum estrus, the feeding time was non-significant among 3 groups but in second estrus, mean time spent on feeding was significantly (p less than 0.05) lower in T0 than T1 and T2 groups. The mean rumination time on d-0 of first estrus was significantly (p less than 0.01) lower in T1 and T2 cows as compared to T0 cows. Mean rumination time on d-0 in second estrus was significantly (p less than 0.05) lower in T1 and T2 than in T0. Mean resting times in first estrus in T1 and T2 were significantly lower (p less than 0.05) than in T0. Mean resting time in d-0 of second estrus was significantly (p less than 0.05) lower in T1 and T2 than the T0. There was no significant difference in the mean dry matter intake and levels of BHBA and NEFA among 3 groups of cows. It was concluded that biostimulation of Sahiwal cows through direct or fence-line bull contact during peri-estrus period highly reduced their feeding, rumination and resting times without affecting their energy balance as compared to non-bull exposed cows.

Published: January 2021

Background: High performance hybrid broilers require a high energy diet to exploit their full genetic potential. Therefore, high energy sources are being used in broiler diet which creates interest in the use of emulsifiers along with fat source. Hence, this study was conducted to evolve emulsifier supplementation strategy in low energy diet containing tallow as fat source in commercial broiler chickens. Methods: Total of 150 day old broiler chicks randomly distributed into three treatments with 5 replicates of ten chicks each. Treatment groups were fed basal diet which contains tallow as energy source (T1), basal diet supplemented with emulsifier at 250g per tonne of feed (T2) and 80 kcal Metabolizable energy reduced from basal diet supplemented with emulsifier at the rate of 250g per ton of feed (T3). Result: At 6th week of age significantly highest body weight was noticed in T2 group, lowest feed intake was recorded in T2 group but feed conversion ratio was comparable between T3 (1.72) and T2 (1.74) groups. No significant difference in carcass parameters and serum biochemical parameters were noticed. Emulsifier supplementation with reduced metabolizable energy can be used as a feeding strategy in broiler chickens to improve the production performance.

Published: January 2021

Background: E. coli is a Gram negative bacterium commonly found in the intestine of animals and humans. Most E. coli are harmless but some can cause infection. Antimicrobial resistance is a public health problem, hence this study was carried out to estimate the antimicrobial resistance pattern and virulotyping of E. coli isolates. Methods: During the period 2018-19, a total of 100 faecal samples from goats (n=50) and sheep (n=50) were processed for isolation and identification of E.coli. All the E. coli isolates were tested for resistance against 10 different antibiotics. The prevalence of various antibiotic resistance genes viz bla TEM, tetA and tetB and virulence genes Stx1, Stx2 and hlyA in all E. coli isolates was determined by PCR. Result: Out of 100 samples, 40 isolates of E.coli (24 from goats and 16 from sheep) were isolated, identified biochemically and by PCR. Majority of the E.coli isolates were found resistant to penicillin (100%) followed by ampicillin (93%), tetracycline, (68.8%), gentamicin (37.4%), ceftriazone (18.8%), amikacin (16.7%), chloramphenicol (4.2%), co- trimoxazole (4.2%) and ofloxacin (4.2%). Out of all the isolates, 12 isolates were positive for blaTEM, 10 for tetB, 19 for tetA, five for Stx1 and hlyA and none carried Stx2 gene.
Tolerance mechanisms of Indonesian plant varieties of yardlong beans (Vigna unguiculata sub sp. sesquipedalis) against drought stress
Authors: Lestari M.W. , Arfarita N. , Sharma A. , Purkait B.
Published: January 2021

Plants that experience drought stress protects themselves through several mechanisms namely avoidance, tolerance, recovery, and escape. Eight varieties of yardlong bean plants were subjected to a drought stress at the rates of 50% of the field capacity (FC) and 100% of the field capacity (FC). The results showed that yardlong bean plants possessed the mechanisms of escape, demonstrated by the increase in Peroxidase (POX) enzyme activity. Avoidance was demonstrated by the reduced evapotranspiration surface of the decreased leaf surface area, and the increased number of closed stomata. Tolerance was demonstrated by the increased proline accumulation.
Performance of some promising germplasm of Fenugreek (Trigonella foenum-graecum L) towards growth and yield and their response to accumulated heat towards rate of flowering and pod development

Published: January 2021

Fenugreek is an important seed spice in India. Both leaves and seeds are used which are rich in protein, vitamin A and vitamin C. It has good potential in medicinal and pharmaceutical industries especially for the presence of trigonellin and diosgenin in the seed. However in spite of all these benefits, the crops have not gained much attention of the growers. This is primarily due to the lack of information on good planting materials and using the same varieties year after years. Fenugreek crop has a definite life cycle that matches seasonal necessity. Within the dynamic range of plant–temperature relations, where short-term responses are readily reversible, phenology and productivity have been successfully linked with various measures of accumulated heat (thermal time), and predictive models validated. Through the present experiment to evaluate some promising germplasms of fenugreek, Agf-1, Agf-2, Agf-3 and the local existing varieties were found to perform well and may be suggested for cultivation in this agro climatic zone. For selection purpose towards contributing seed yield, some attributes like plant height, number of branches, pod length, seed weight per pod may be taken into consideration.

VOLUNNTARY COMPLIANCE DENGAN KONSEP KEADILAN PAJAK PERSPEKTIF IBNU KHALDUN BAGI WAJIB PAJAK
Authors: Andriani Sri
Published: January 2021

This research is to identify and analyze the concept of voluntary compliance with the concept of Ibn Khaldun's perspective of tax justice for tax duty. Research with qualitative descriptive type which uses data through interviews with participants: religious leaders, tax officials, tax consultants, tax academics based on the slippery slope framework research results show that voluntary compliance / tax compliance can be defined as mandatory will taxes to be subject to tax regulations in a country. The measurement of compliance that is measured by the knowledge and concept of justice shows that 25 respondents chose strongly agree and 12 respondents chose agree from 37 respondents, meaning that the community realized that tax was the country's biggest source of revenue. Public knowledge about self-assessment shows an average of 3.35, which means that the community has the potential to choose neutral in their knowledge, and 3.3 which shows the level of tax compliance. This tax compliance behavior arises because there is a fairly regulated income tax system, the way income tax is fairly distributed to each taxpayer, and the income tax that is charged is carried out fairly. The principles of convenience and productivity in the realization of taxes which are considered oppressive are emphasized with the concept of equality and neutrality. In other words, someone's awareness is recognized by how much someone's knowledge about the law, that someone's awareness is recognized by how much someone's knowledge about the law.

Published: January 2021

Tanto el concepto de límite como el de musicalidad poseen en la obra de José Ángel Valente un valor axial. Con el presente trabajo, se pretende vincular la poética de Valente con los presupuestos de la corriente espectralista. Con vistas a este propósito se revisarán los fundamentos de la poética de madurez del gallego y se contrastarán con las bases teóricas del espectralismo. La condición permeable y fluctuante del concepto de límite se impone en ambos objetos trabajados –música espectral y poesía de Valente–. Podría decirse que lo reverberante constituye el fundamento epistemológico e incluso ontológico de ambas propuestas estéticas. El modo en que tanto la poesía como la música estudiada se proponen como vías de conocimiento pasa por un curso de exploración de la propia materialidad. El conocimiento de sí posee la cualidad de objeto estético.
La cuestión del territorio en la poesía argentina contemporánea: objetivismo, «poesía de los noventa» y un experimento en la Antártida
Authors: Baigorria Martín
Published: January 2021

El territorio, entendido como una atención particular al espacio en términos de realidad local, permite pensar algunas innovaciones importantes surgidas en la poesía argentina contemporánea. La dialéctica entre habla e imagen que caracteriza a una parte importante de la «poesía de los noventa» puede servir para examinar los puntos de contacto entre la percepción subjetiva, las transformaciones del espacio social actual y las controversias históricas que rodean a muchas de estas cuestiones. El guadal (García Helder) y La zanjita (Desiderio) constituyen dos extremos compositivos que respectivamente nombran la experiencia actual del territorio mediante la observación o la experimentación con el habla. Esas posibilidades, no excluyentes entre sí, vuelven a hallarse en El cielo de Boedo (Durand), Poesía civil (Raimondi) o Hatuchay (Cucurto). Poesía civil y Pujato (Cortiñas) profundizan en la tematización de asuntos que se remontan al ensayo argentino del siglo XX; tanto la reflexión sobre los símbolos colectivos como la problemática de la identidad y sus vínculos con el territorio son para estos autores problemas muy actuales.
Diarios falsos, confesiones fabuladas y rostros hechos a medida: las performances intimistas de Alan Pauls
Authors: Rodriguez Montiel Víctor Emiliano
Published: January 2021

Este trabajo desarrolla una lectura crítica de las incursiones egotistas de Alan Pauls. Su propósito es reflexionar acerca de las estrategias de autofiguración a las que este autor apela para intervenir su material autobiográfico. Para ello, se parte del siguiente supuesto: la narración de eso que llamamos «vida», para un dandi como lo es Pauls, no se deja al arbitrio de los valores que cimentan, en su sentido más vulgar, la práctica de la confidencia (léase búsqueda de autenticidad, franqueza, espontaneidad). Lejos de presentársele como un stock de testimonios fidedignos, la «vida» no es otra cosa para Pauls que pura actuación, montaje, performance. Esta argumentación, dividida en tres partes (la primera centrada en La vida descalzo, la segunda en sus diarios falsos y la tercera en la importancia de la figura paterna), sostiene como hipótesis que los ejercicios confesionales de Alan Pauls, a pesar de las medidas profilácticas que toma para repeler la pretensión de verdad, dejan entrever la persistencia de ciertos impulsos íntimos vinculados con su padre, Axel.

La Palabra sobrevive a un año más de trabajo editorial. Por lo tanto, es importante hacer un balance de 2020. Varias han sido las circunstancias que han variado nuestro trabajo en este año de pandemia, donde pudimos, recurriendo a la usanza de muchas otras revistas, haber convocado un número sobre literatura y pandemia o algo por el estilo, esto podría responder a la lógica de la vida actual donde la actualización genera resultados en reproducciones, diseminación de información masiva y distribución de esta por la red. No quisimos responder a esa lógica sino que respetamos el proceso editorial que se había planeado desde el año pasado.

Método para la solución de tareas experimentales cualitativas de biología
Authors: García Dayly , Guerra Yusimí , Leyva Julio
Published: January 2021

Se aborda la problemática de la baja independencia cognoscitiva de los estudiantes al realizar las prácticas de laboratorio de biología. Para atenuarla, se propone transformar las prácticas de laboratorio tradicionales en tareas experimentales e introducir un método para orientar a los estudiantes en la solución independiente de las tareas experimentales cualitativas de biología. Dicho método fue obtenido por analogía. Para la validación de la propuesta, se realizó un experimento de modelo y una intervención práctica, donde se siguió una secuencia de apertura en una muestra de estudiantes de la Licenciatura en Educación, Biología. Desde el punto de vista estadístico, se aplicó un diseño de bloques completos al azar para comparar la independencia cognoscitiva de los estudiantes en las diferentes etapas del método de solución, y de los estudiantes entre sí. Como resultado del experimento, se evidenció la funcionalidad del método para el diseño de las tareas experimentales correspondientes a las disciplinas biológicas. En la intervención práctica se detectaron regularidades didácticas, que permitieron obtener avances significativos en la independencia cognoscitiva de los estudiantes de la muestra.
Diseño e implementación de una secuencia didáctica para la enseñanza del concepto de elemento químico
Authors: López Dulce María
Published: January 2021

Este estudio propone la implementación de una secuencia didáctica basada en el modelo de aprendizaje como investigación orientada, para la enseñanza del concepto de elemento químico en la educación secundaria. Su diseño se ha basado en las ideas previas de los estudiantes y en el análisis histórico sobre este concepto. La evaluación se ha realizado al comparar grupos de estudiantes que han seguido esta secuencia didáctica con grupos de estudiantes que han mantenido una enseñanza tradicional. Los resultados revelan que los estudiantes de los grupos experimentales respecto a los grupos control: 1) presentan un mejor manejo en la definición procedimental de sustancia en el nivel macroscópico; 2) definen mejor el concepto de elemento químico en el marco de la teoría daltoniana; 3) distinguen mejor los conceptos de sustancia simple y elemento químico; y 4) presentan una mejor distinción del concepto microscópico de mezcla —de sustancias simples o de sustancias compuestas— cuando es utilizada una secuencia didáctica de orientación constructivista.

Minimax differential game with delay
Authors: Kim Arkadii V. , Bocharov Gennady A.
Published: January 2021

The paper considers a minimax positional differential game with aftereffect based on the i-smooth analysis methodology. In the finite-dimensional (ODE) case for a minimax differential game, resolving mixed strategies can be constructed using the dynamic programming method. The report shows that the i-smooth analysis methodology allows one to construct counterstrategies in a completely similar way to the finite-dimensional case. Moreover as it is typical for the use of i-smooth analysis, in the absence of an aftereffect, all the results of the article pass to the corresponding results of the finite-dimensional theory of positional differential games.
Fractional order differential pursuit games with nonlinear controls
Authors: Mamatov Mashrabjon Sh. , Alimov Khakim N.
Published: January 2021

The article is devoted to the problems of extending the results and methods of the theory of differential games and optimal control to systems of fractional order. The research is motivated by numerous applications of fractional calculus in control problems of industrial facilities, chemical and biochemical plants, etc. The article considers the problem of pursuit in games represented by nonlinear differential equations of arbitrary fractional order in the sense of Caputo. To study this pursuit problem, we use an approach similar to the method of L. S. Pontryagin, developed for linear differential games of integer orders. In this paper, new sufficient conditions are obtained for solving the pursuit problem in the class of games under study. It has been proven that if these conditions are met, the game can be completed within a certain limited period of time. When solving the pursuit problem, we also used the representation of the solution to a differential equation in terms of generalized matrix functions.
Level of Effectiveness for ERP System in Improving the Educational Process in Higher Education Institutions in Yemen: A Case Study of the University of Science and Technology
Authors: Ali AL-Mandi Mohammed , AL-Sharjabi Abdulrahman
Published: January 2021

This study aimed to identify the level of effectiveness of the Enterprises Resource Planning (ERP) in improving the educational process in higher education institutions in Yemen. The case study was carried out in the University of Science and Technology (UST). The study adopted the analytical descriptive method, using a questionnaire, which was distributed to the whole population (90 employees), who deal with the ERP system at the university, and who were selected by the complete census method. Only 74 questionnaires were returned and were subject to statistical analysis. Major findings revealed that there was a statistically significant correlation between the dimensions of the questionnaire and the overall effectiveness of the ERP system at the university. Therefore, this result indicates that there is a high degree of effectiveness of the ERP system in improving the educational process with a high agreement score on the dimensions of the questionnaire. It was found that the highest effectiveness degree was in the dimension of admission and registration support, followed by academic support and student affairs, and the lowest degree was in the dimension of technical support. Overall, the level of application of the ERP system at the university was high. Based on these findings, it was recommended that this system should be applied so as to cover all departments that do not use the ERP system, which would lead to effective and efficient performance of such departments.

Keywords: ERP system effectiveness, educational process, higher education institutions

The paper describes a clinical case of hypersensitivity pneumonitis in a young patient during the COVID-19 pandemic when the patient having complaints of dyspnea and interstitial lung changes as ground glass opacity was initially unambiguously diagnosed with viral COVID-related bilateral pneumonia. The chief computed tomography manifestations in the lung were infiltrative inflammatory changes as numerous areas of predominantly interstitial infiltration by the type of ground glass, with consolidation areas and reticular changes, varying in extent, peripheral localization, mainly in the lower lobes and with the 25–50% involvement of the right and left lung parenchyma. The diagnosis of hypersensitivity pneumonitis was confirmed by cytological and histological examinations of the biopsy material obtained during bronchoscopy using a set of biopsies and endobronchial cryobiopsy.This clinical case demonstrates that the chest computed tomography detection of pulmonary ground glasstype changes is a reason for further patient examinations and requires morphological verification of the diagnosis, since the cost of a diagnostic error is the life of a patient.

Thyroid sonography as an extension of the bedside examination in hyperthyroidism
Authors: KYRIACOU ANGELOS , Syed Akheel A , Economides Panayiotis A
Published: January 2021

In this mini-review, we examine the utilization of thyroid sonography as a ‘point-of-care’ tool for assessing and managing patients with (suspected) hyperthyroidism who present to the endocrine outpatients. Thyroid USS may aid the distinction between hyperthyroidism and destructive thyroiditis. Presence of intense vascularity (‘thyroid inferno’) on power Doppler has a very high positive predictive in identifying hyperthyroidism. It may also allow the sub-classification of hyperthyroidism into autoimmune and nodular hyperthyroidism. The presence of thyroid nodules is important to acknowledge at an early stage as this may affect management. Not only toxic nodules are managed with definitive treatment, but the presence of nodules is important to be clarified in Graves’ disease because of the evidence of an increased risk of malignancy and, possibly, more aggressive behaviour if malignant disease is confirmed. Current guidelines on hyperthyroidism do not clearly state thyroid sonography as a first line investigation although recent authoritative reviews point in that direction. Given the aforementioned benefits of thyroid sonography, alongside the reduced costs and widespread availability of high-resolution (including portable) ultrasound devices, there is an argument for thyroid sonography to be applied as a first line investigation for all patients with hyperthyroidism. More precisely, formally trained endocrinologists could perform thyroid sonography as an extension of their clinical examination when patients first present with hyperthyroidism in the endocrine clinic.
