The role of uncertainty of measurement In conformance testing
Authors:   National Laboratory Association, Sidney Steve
Published: March 2022

The vast majority of routine testing that takes place requires that the laboratory or the customer of the laboratory evaluates the test results in terms of either prescribed (regulations) or production limits. In more recent times simple acceptance rules that have been established over time have given way to a more ´scientific’ approach. These new ideas are intended to provide users of test and calibration reports that are specifically used for Conformance Testing, with more comprehensive support when the data is questionable. This paper reflects on what is questionable data, how it arises and makes reference to a new guidance document that was developed by the BIPM Joint Working Group on Guides • WG1 and published in 2012. It tackles the thorny question of Uncertainty of Measurement in Conformance Testing and provides a number of approaches which can be taken to help resolve issues that may arise. Although the BIPM, and this working group in particular, have traditionally focused on metrological issues, this approach will be of interest to all laboratories. As the role of uncertainty of measurement impacts more and more on certificates being issued, laboratories need to not only be aware of the effect that this has on conformance testing, but also be knowledgeable about how to answer customer’s queries in this regard. It is also hoped that authorities and regulators will start to adopt some of these ideas in order to avoid the cost or risk of incorrect decisions and it is hoped that this will also have a positive effect on decisions made as a result of laboratory data.
The need for a Dynamic Pressure Calibration Standard
Authors:   The Modal Shop, Schiefer Mark I.
Published: March 2022

Global need for dynamic pressure measurements is increasing rapidly. Dynamic pressure sensors are being used in all sorts of high value measurements from Gas Turbine stability control to liquid gas transport systems design and management. While there are several manufacturers of sensors which are capable of measuring dynamic pressure there is no standardization of calibration techniques. There is also little to no dynamic pressure sensor calibration expertise at the national metrology level, and thus no proficiency or international comparisons being carried out. There are also no international standards covering the topic. This paper will give an overview of the dynamic pressure calibration offerings by the various supplier organizations, including basic operating principles of each. It will furthermore cover current standardization efforts both within the ISA and ISO organizations. Lastly it will cover the intended format and outline of a newly formed TC108 working project intended to generate a dynamic pressure calibration standard.
The Transfer of Expert Tacit Knowledge in Industry
Authors:   Purdue University, Pippenger Brian
Published: March 2022

Industry today is as much knowledge based, as it is practical operational based. The business of knowledge is vital to the operation of the facility as is the machinery the product is manufactured. The tacit knowledge of people is difficult to capture in an explicit form, this includes professional insights, judgment, rules of thumb, intuition and subtle issues known by subject matter experts. Tacit knowledge tends not to be formally documented but can be crucially important to communicate to the organization and is a sustainable competitive advantage. Tacit knowledge is lost upon departure of its carriers from the project or from the organization and cannot be applied to other projects or even in later stages of the same project.
Calibration Set-up for Reference Radiosondes Meeting GRUAN Requirements
Authors:   Centre for Metrology and Accreditation • MIKES, Sairanen Hannu
Published: March 2022

Accurate and reliable weather observations are necessary for transport, industry and everyday living. Along with ground observations upper air observations provide data for forecasts and for climate change studies However, the quality of upper air measurements does not yet fulfil the requirements of climatologists [1] but improved methods and procedures are needed. To enhance the quality Global Climate Observing System (GCOS) has established GCOS Reference Upper-Air Network (GRUAN) comprising about 40 stations that will provide reference observation data for the global radiosonde station network. GRUAN has specified targets and their priority for measurements of all important parameters at upper troposphere and lower stratosphere [2]. Water vapour pressure is one of the first priority parameters with the uncertainty requirement of 2 % in terms of mixing ratio at the measuring range from 0.1 to 90000 ppm [3]. In order to meet the water vapour accuracy requirements set by GRUAN traceable calibrations for radiosondes are needed. Due to a short lifetime and a high calibration cost comparing to price of a sonde GRUAN aims to ensure radiosondes stability, traceability and uniformity by standards [4]. Regardless of that GRUAN requires calibration and traceability to SI for each radiosonde in order to be accepted to GRUAN [4]. This work presents a new apparatus for reference radiosonde calibrations meeting the GRUAN uncertainty requirements. The apparatus was designed to meet the requirements and still to be quick enough for practical calibration use. Applying a hybrid humidity generator method [5] with two saturators, the high accuracy of a single pressure generator and the short stabilisation time of a flow mixing generator are achieved in a single apparatus. The operation range covers dew-point temperatures from 183 K to 283 K and air temperatures from 183 K to 293 K. This paper presents the design of the apparatus with a preliminary uncertainty analysis.

Authors:   Technical Center for Information Technology and Electronics, Mihm Gerhard
Published: March 2022

SAP is a well-known name in the business management software market. The German Armed Forces Calibration Service uses SAP for more than two years now. Announced as “a perfect business solution”, SAP first turned out to be a nightmare and finally became a useable tool •with advantages and disadvantages, too. The presentation will give an overview over the experiences made. It will include the idea behind the system, show en detail how every single piece of test- and measurement equipment • known as “equipment” or “equi” - has to be set up in the system, explains how service plans and on-time notifications have to be handled, how templates have to be created and how customers and calibration technicians have to work with this software. The presentation will not try to sell SAP • but give an idea how the equipment management of test- & measurement equipment can be handled and might help to make decisions.
Calibration Requirements and Good Practices for Modular Instuments
Authors:   National Instruments, Nieves Dimaries , Robinson Patrick
Published: March 2022

A monitoring, measuring, or testing activity with test instruments is only useful and effective when the measurement results are reliable. To ensure the reliability of the measurement results from the test instruments, a calibration must be performed. Every electronic device needs a calibration schedule to verify its performance. As with traditional instrumentation, modular instruments should be verified and adjusted in a consistent manner to ensure its performance and to maintain its accuracy over time. However, unlike traditional instrumentation, modular instruments have additional requirements and considerations that need to be accounted for in order to perform a proper verification and adjustment process. As you may know, modular instrumentation consists of a combination of chassis, embedded controller and modules, and each module needs to be considered and maintained in order to obtain a consistent and reproducible process. Additionally, a software application is necessary in order to communicate with the instruments and obtain the results. The impact of these system aspects is not always considered. In this paper, calibration requirements and considerations that may influence the quality and confidence of the results for a modular instrument calibration process will be presented. Good Calibration Practices for modular instruments are defined and explained in order to considered and applied during the process. These good calibration practices also can be used by end users to ensure the quality of their measurements.
Global simulation of dissolved 231Pa and 230Th in the ocean and the sedimentary 231Pa∕230Th ratios with the ocean general circulation model COCO ver4.0
Authors: Sasaki Yusuke , Kobayashi Hidetaka , Oka Akira
Published: March 2022

Abstract. Sedimentary 231Pa/230Th ratios provide clues to estimate
the strength of past ocean circulation. For its estimation, understanding
the processes controlling the distributions of 231Pa and 230Th in
the ocean is important. However, simulations of dissolved and particulate
231Pa and 230Th in the modern ocean, recently obtained from the
GEOTRACES project, remain challenging. Here we report a model simulation of
231Pa and 230Th in the global ocean with COCO ver4.0. Starting
from the basic water-column reversible scavenging model, we also introduced
the bottom scavenging and the dependence of scavenging efficiency on
particle concentration. As demonstrated in a previous study, the
incorporation of bottom scavenging improves the simulated distribution of
dissolved 231Pa and 230Th in the deep ocean, which has been
overestimated in models not considering the bottom scavenging. We further
demonstrate that introducing the dependence of scavenging efficiency on
particle concentration results in a high concentration of dissolved
230Th in the Southern Ocean as observed in the GEOTRACES data. Our best
simulation can well reproduce not only the oceanic distribution of
231Pa and 230Th but also the sedimentary 231Pa/230Th
ratios. Sensitivity analysis reveals that oceanic advection of 231Pa
primarily determines sedimentary 231Pa/230Th ratios. On the other
hand, 230Th advection and bottom scavenging have an opposite effect to
231Pa advection on the sedimentary 231Pa/230Th ratios,
reducing their latitudinal contrast. Our best simulation shows the realistic
residence times of 231Pa and 230Th, but simulation without bottom
scavenging and dependence of scavenging efficiency on particle concentration
significantly overestimates the residence times for both 231Pa and
230Th in spite of similar distribution of sedimentary
231Pa/230Th ratios to our best simulation.
Brief communication: Application of a muonic cosmic ray snow gauge to monitor the snow water equivalent on alpine glaciers
Authors: Gugerli Rebecca , Desilets Darin , Salzmann Nadine
Published: March 2022

Abstract. Monitoring the snow water equivalent (SWE) in the harsh environments of high mountain regions is a challenge. Here, we explore the use of muon counts to infer SWE. We deployed a muonic cosmic ray snow gauge (μ-CRSG) on a Swiss glacier during the snow-rich winter season 2020/21 (almost 2000 mm w.e.). The μ-CRSG measurements agree well with measurements by a neutronic cosmic ray snow gauge (n-CRSG), and they lie within the uncertainty of manual observations. We conclude that the μ-CRSG is a highly promising method to monitor SWE in remote high mountain environments with several advantages over the n-CRSG.
Engagement in Mindfulness Exercises during Large Lectures and Students’ Writing Self-Efficacy
Authors: Drewery David W. , Westlund Stewart Nicole , Wilson A. Wade
Published: March 2022

The purpose of this study was to examine the association between greater engagement (i.e., number of times participated) in mindfulness exercises administered in large university lectures and students’ writing self-efficacy. For eight weeks, a breathing exercise was administered to students in one lecture section, and a progressive muscle relaxation (PMR) exercise was administered to students in another lecture section of the same course. Participants (n = 147) completed measures of writing self-efficacy before (T1) and after (T2) the eight-week exercise period. Engagement was greater in the breathing exercise than in the PMR exercise (p < .05). Writing self-efficacy was marginally greater (p = .08) at T2 for those administered the breathing exercise than for those administered the PMR exercise. Correlational analyses further showed that engagement in the breathing exercise was associated with writing self-efficacy at T2 (p < .01), but engagement in the PMR exercise was not (p = .21). We conclude with implications for course instructors using mindfulness exercises to enhance desirable writing outcomes.

Published: March 2022

Background/Aims: Patients with ulcerative colitis (UC) are at an increased risk of certain infections and malignancies compared with the general population. Incidence rates (IRs) of hospitalized infections, herpes zoster (HZ), and malignancies in patients with UC, stratified by treatment, in Japan were estimated.Methods: This retrospective study identified patients with UC treated with corticosteroids, immunosuppressants, or tumor necrosis factor inhibitors (TNFi) from 2 administrative databases (Japan Medical Data Center [JMDC] and Medical Data Vision [MDV]). IRs (unique patients with events per 100 patient‐years) were estimated for hospitalized infections, HZ, and malignancies, between June 2010 and May 2018.Results: Among 6,033 MDV patients with UC receiving corticosteroids, immunosuppressants, or TNFi, IRs (95% confidence intervals) were: hospitalized infections, 1.73 (1.52–1.93); HZ, 1.00 (0.85–1.16), and malignancies, 1.48 (1.29–1.66). Among 958 JMDC patients with UC receiving corticosteroids, immunosuppressants, or TNFi, IRs (95% confidence intervals) were: HZ, 1.82 (1.27–2.37) and malignancies, 1.35 (0.87–1.82). In both cohorts, IRs of malignancies were generally similar among patients receiving immunosuppressants, TNFi, or combination therapy (immunosuppressants and TNFi); this was also true for IRs of hospitalized infections and HZ in the MDV cohort. IRs of hospitalized infections, HZ, and malignancies were higher in patients receiving calcineurin inhibitors compared with immunosuppressants or TNFi, in both cohorts.Conclusions: IRs of hospitalized infections, HZ, and malignancies among patients with UC were generally similar regardless of UC treatment, except for calcineurin inhibitors.

This research aimed to determine the influence of stress of various etiologies in pigs caused by transportation and pre-slaughter conditions on meat quality. For this purpose, pigs were divided into 11 groups within two meat processing enterprises, depending on the duration of transportation (short, long without breaks and long with breaks) and the conditions of keeping animals before slaughter. Also, within the two groups were created two subgroups with pigs of different breeds. A total of 156 pigs were studied. Blood was collected from all pigs to determine cortisol and lactate levels, and a sample of meat from the longest back muscle. The pH of the meat was determined at different stages of its maturation, and the weight loss of the sample was determined. As a result of the research, it was found that the highest quality pork was obtained from pigs that experienced lower levels of stress before slaughter. Keeping pigs for 10 – 14 hours before slaughter without access to water and food resulted in higher stress levels, which were probably expressed in higher blood concentrations of cortisol and lactate. Pigs’ access to food and water during pre-slaughter retention allows for high-quality meat by reducing the influence of stress. Pigs’ access to water before pre-slaughter does not affect the stress level but positively affects the loss of meat weight during maturation. The higher the concentration of lactate in pigs’ blood, the faster the pH of the meat decreases after slaughter, which negatively affects its quality and moisture retention. If there is a long-term transport of pigs, there is no rest stop that can significantly reduce stress levels in pigs. Duration of transportation of pigs does not correlate with stress levels, as the conditions before slaughter content.

Authors: Jakhrani Abdul Qayoom
Published: March 2022

Performance of solar photovoltaic water pumping units relies on available solar radiations of the area, geographical conditions and system configurations. This study was conducted to analyze the influence of solar radiation, motor speed and water head on water discharge of a solar water pumping systems (SWPS). For that, a SWPS was installed, configured and its performance was examined at Sadiqabad Colony, Nawabshah for two consecutive months from 12:00 to 13:00 hours. Light meter, Model- HDS 2302.0, Delta OHM was used for measurement of global solar radiation, PROVA-RM 1000 tachometer for motor pump speed and stopwatch for recording of elapsed time for filling up of 30 liters capacity water can. Results revealed that the average minimum solar radiations were 776 W/m2 at 12:00 hours in the month of May and maximum 902 W/m2 at 13:00 hours in the month of June during experimental work. The maximum average motor speed and flow rate were noted at L1 and minimum at L4, whereas, the maximum time taken by the solar water pumping system for filling up of water can at L4 and minimum at L1. The time taken to provide one liter of water was found inversely proportional with motor speed and directly with the water head.
Numerical Analysis of Stability of a Road Embankment Subjected to Floods
Authors: Bhutto Amjad Hussain
Published: March 2022

In the floodplains of the river Indus several road embankments have been failed due to the action of floods. The main motivation for this study is to analyse how much high floods a typical road embankment could sustain and to suggest remedies to prevent failure if the flood is exceptionally high. For this purpose, an 8 m high road embankment located in flood region of the Indus river was analysed for stability when subjected to 4 m and 7 m high floods. Numerical analysis was performed with finite element program PLAXIS 2D. The results showed that the road embankment was stable prior to occurrence of the flood. The road embankment became instable when it was subjected to flood water of 4 m. This implies that the road embankment might not withstand pressure of the flood water higher than 4 m. The analysis suggested that the road embankment could fail if the flood water is 7 m high. To stabilize the road embankment when subjected to 7 m high flood, rockfill berm was utilized on the downstream side. Optimization analysis was conducted to use minimum volume of rockfill in order to reduce costs. The findings of this study could be beneficial to practicing engineers involved in maintenance of road embankments in floodplains

               Basically, when inflation, interest rates and exchange rates increase, the Composite Stock Price Index will decrease. The problem in this study is that in fact inflation, interest rates and exchange rates have increased, in fact the Composite Stock Price Index has increased. This study aims to determine the effect of inflation, interest rates and exchange rates on the Composite Stock Price Index on the Indonesia Stock Exchange. This type of research is associative, with a quantitative approach. This study takes all data in time series including inflation, interest rates, exchange rates and the Composite Stock Price Index for the 2015-2019 period. The sample in this study used a saturated sampling of 60 samples. The analysis technique used is multiple linear regression, classical assumption test and hypothesis testing. The partial test results show that inflation and exchange rates have no effect on the Composite Stock Price Index, interest rates have a significant negative effect on the Composite Stock Price Index. Simultaneous test results show that the variables of inflation, interest rates and exchange rates have a significant effect on the Composite Stock Price Index. The value of the coefficient of determination in this study is 0.451. This means that the ability of the independent variable to explain the dependent variable is 45.1%, while the rest is explained by other variables not included in this study.

Authors: Singh Amith A , Gupta Ravi , Swetha Swetha , Rao Bharath
Published: March 2022

Introduction: Restored teeth in the course of chewing or when exposed to thermal stimuli may lead to sensitivity. One of the significant reasons for sensitivity is microleakage. The repercussion of unaddressed microleakage leading to secondary caries and further on. The purpose of this study was to compare the microleakage of amongst different types of restorative materials which were silver amalgam and micro-hybrid composite resin with 7th generation bonding agent. And also to examine the effect of carbonated drink on microleakage. Materials and method: Forty extracted premolars were used for the study. Class V cavities were prepared on the buccal surfaces of the teeth, 1mm above the cementoenamel junction cervico-occlusal. Twenty cavities were restored with silver amalgam, and the remaining with composite resin. Group I and Group II both comprised of 10 teeth with silver amalgam restoration and ten teeth with composite resin restoration were immersed in the carbonated drink and water respectively for 15 minutes for ten days. The teeth were later immersed in methylene blue, sectioned and evaluated under a microscope. Statistical analyses used were Fisher's exact test. Result: Silver amalgam showed highest microleakage tendency in the carbonated drink, (P > 0.05). In water, silver amalgam had the least tendency for microleakage. However, composite resin did not statistically significant microleakage in both carbonated drink and water. Conclusion: The silver amalgam restorations showed microleakage in both carbonated drink and water. The microleakage was significantly higher in the carbonated beverage. On the other hand, composite resin restoration showed microleakage neither in carbonated drink nor water.

Published: March 2022

¿Existe alguna razón para preferir que la gestión de los daños que nos causamos unos a otros sea mediante un sistema de responsabilidad civil en lugar de un fondo social de compensación? La justificación de los fondossociales de compensación es más bien obvia, pues se intenta atender con celeridad las necesidades de las víctimas. En cambio, la justificación de la responsabilidad civil genera amplias controversias. Si la responsabilidad civil ha de ser justificada, parece que debe encontrarse en ella un valor que no puede ser perfectamente realizado con mecanismos alternativos. Ese será su valor intrínseco. En este trabajo se ofrece una visión de cuál es ese valor, y se argumenta que en última instancia resulta insuficiente para justificarplenamente la responsabilidad civil.
Toward Abiozoomorphism in Social Robotics? Discussion of a New Category between Mechanical Entities and Living Beings
Authors: Parviainen Jaana , Turja Tuuli
Published: March 2022

Social robotics designed to enhance anthropomorphism and zoomorphism seeks to evoke feelings of empathy and other positive emotions in humans. While it is difficult to treat these machines as mere artefacts, the simulated lifelike qualities of robots easily lead to misunderstandings that the machines could be intentional. In this post-anthropocentrically positioned article, we look for a solution to the dilemma by developing a novel concept, “abiozoomorphism.” Drawing on Donna Haraway’s conceptualization of companion species, we address critical aspects of why robots should not be categorized with animals by showing that the distinction between nonliving beings and living beings is still valid. In our phenomenologically informed approach to social robotics, we propose that the concept of abiozoomorphism makes it possible to transcend the strong ethos of biotism that prevails in both robot design and academic research on social robots.

Educação a Distância – teoria e prática
Authors: Do Nascimento Cinara Ourique , Lemos Sainz Ricardo
Published: March 2022

Nosso objetivo foi provocar reflexões sobre as rupturas e sentidos que a utilização da modalidade de Educação a Distância – EaD traz à Educação Profissional. Buscando contribuir na produção de conhecimento, desenvolvemos um texto na forma ensaística, oferecendo reflexões sobre o espaço relacional dos cursos técnicos a distância do Instituto Federal de Educação, Ciência e Tecnologia Sul-rio-grandense (IFSul). Apresentamos acontecimentos, ideias e reflexões teorizadas que unem o sujeito professor, a EaD e a instituição. Por fim, este ensaio serve àqueles que desejam se aventurar na utilização da EaD, rompendo com a cultura institucional, reinventando-se na práxis educativa e, principalmente, na compreensão de que a EaD está longe de ser concebida numa visão representacionista da realidade.
Extensão Universitária na EaD: além das fronteiras físicas da Universidade
Authors: Correia de Almeida Ana Carolina
Published: March 2022

Este relato tem como objetivo refletir sobre a extensão universitária na Educação a Distância considerando o desenvolvimento das ações extensionistas do Centro de Apoio à Educação a Distância (CAED) da Universidade Federal de Minas Gerais (UFMG). O trabalho ora apresentado relata a experiência na coordenação de cursos, programas, projetos e eventos de extensão acadêmica. Tal processo pressupõe difundir o conhecimento produzido dentro da universidade e, ao mesmo tempo, criar condições que possibilitem absorver a cultura da comunidade externa. Dessa forma, conclui-se que a extensão deve fazer parte do cotidiano dos cursos a distância ministrados pela universidade, e, assim como a pesquisa, devem ser inseridos no mesmo horizonte em que são ofertados nos cursos presenciais.

Formação docente para a inclusão: impacto do Plano Nacional de Educação no Plano Municipal
Authors: Carvalho Ambrosina Suely de , Assis Renata Machado de
Published: March 2022

A presente reflexão tem o propósito de discutir a formação docente em uma perspectiva inclusiva, à luz da legislação educacional, nacional e municipal. Intencionamos discorrer sobre: formação continuada de professores para a inclusão no Brasil; e a legislação brasileira para a formação de professores da educação inclusiva. O problema que investigamos foi: como vem ocorrendo a formação continuada dos professores no Plano Municipal de Educação (PME) em um município do Centro-Oeste brasileiro? Os objetivos propostos foram: analisar como ocorre a proposta de formação continuada com destino à educação inclusiva no Plano Nacional de Educação (PNE) de 2014 e discutir as orientações, sobre isso, no PME de 2015. Fundamentamos nossas reflexões em autores que abordam a formação docente nas diversas dimensões e na legislação existente. Os resultados demonstraram que, ao se referir à formação continuada, há lacunas a serem enfrentadas. A legislação se mostra mais propositiva do que interventiva, no que se refere à efetivação da formação docente para o trabalho com a inclusão. Este estudo detectou a necessidade de políticas públicas voltadas à formação continuada de professores para a inclusão.
Máscaras do racismo e inscrições corporais negras: entre mistificações, o desaparecer de si e a resistência
Authors: Oliveira Carlos Adriano da Silva , Paula Silva Maria Cecília de
Published: March 2022

O artigo reflete acerca do conceito de corpo, em especial as inscrições corporais negras no Brasil. Trata-se de resultados de uma investigação que objetiva compreender as marcas (efeitos) de sentido de docentes universitários sobre inscrições corporais negras no Centro de Formação de Professores da Universidade Federal do Recôncavo da Bahia (CFP/UFRB). Utiliza-se uma abordagem qualitativa mediada por elementos da metodologia da pesquisa histórica do tempo presente, tendo como técnica de análise de dados a produção de sentidos. O estudo ampliado conta com a produção de dados indicando levantamentos de artigos científicos e teses. Também conduzimos entrevistas em ambiente virtual com docentes e analisamos imagens no campo empírico da pesquisa. Como resultados desse artigo problematizamos a existência de mistificações históricas que perpetuam a sentença de convívio habitual com o racismo. A presença de máscaras do racismo é tensionada por estratégias de reparação e resistência, amparadas no reconhecimento das inscrições corporais negras e materialidade da vida.
Adaptações curriculares como componente da formação docente
Authors: Yamauchi Torres Érica , Silva Nery Magda , Santos Gonçalves Barreto Bezerra Claudia
Published: March 2022

Este estudo analisa a compreensão de docentes sobre as adaptações curriculares para os estudantes público-alvo da educação especial e as ações da formação continuada destes profissionais em relação à construção de uma escola na perspectiva inclusiva. Desenvolveu-se uma pesquisa aplicada e qualitativa, a qual se enquadra como um estudo de caso. O tema das adaptações curriculares é relevante na medida em que estas manifestam um olhar educacional específico, sendo uma prática pedagógica inclusiva, além de ser um componente na formação continuada docente. Os resultados foram discutidos fundamentados em aspectos legais que versam sobre a educação inclusiva, dialogando com pesquisadores como Capellini (2018), Pletsch (2009), entre outros. A partir da análise dos dados, foi possível averiguar que os docentes percebem e realizam adaptações curriculares isoladamente, o que caracteriza lacunas na formação desses docentes e o descumprimento das políticas públicas inclusivas.

Authors: Oliveira Marcos Martins de , Oliveira Giovanna Lianne Teran Villanueva de , Quineteiro Jose Reinaldo
Published: March 2022

Sabemos que son grandes los desafíos para implementar una educación inclusiva para todos. El problema que guió este ensayo de investigación fue: ¿la capacitación inicial de profesores garantiza la cualificación teórica y practica para implementar una escuela inclusiva para estudiantes con deficiencia? Los objetivos propuestos fueron: reflexionar sobre la capacitación inicial y continua de profesores y la construcción de una escuela inclusiva; analizar la capacitación docente en una perspectiva inclusiva; presentar lineamentos de la Base Nacional Común curricular para la Capacitación Continua de Profesores de Educación Básica. Resultados nos mostraron que la capacitación inicial en las universidades aún es precaria. Nuestras consideraciones nos hicieron reflexionar sobre la necesidad de invertir en la capacitación inicial y continua de profesores para actuar con las diferencias en el espacio escolar.

Radar-climatology of Delhi and neighbourhood : spatial and. . diurnal variations of precipitation echo distribution
Authors: KULSHRESTHA S. M. , JAIN P. S.
Published: March 2022

The paper presents a radar-climatological analysis of the New Delhi radar data for a period of 31 months (December 1957 to June 1960). The object is to investigate the space and time variations of precipitation echo distribution within a range of 200 miles round the radar station. The distribution of areal coverage as well as that of the heights of precipitation echoes in the area have been studied both on a month-by-month and a seasonal basis. The diurnal variations of areal and height distributions have also been studied for all the months.
ANALIZA POSLOVNIH I FINANSIJSKIH REZULTATA PRIVREDE SRBIJE U PERIODU 2014-2020., SA OSVRTOM NA DOPRINOS NARODNE BANKE SRBIJE
Authors: Janković Stojan
Published: March 2022

Srpska privreda je u periodu od 2014. do 2020. godine znatno poboljšala svoj poslovni i finansijski položaj, o čemu svedoči povećanje poslovne aktivnosti i profitabilnosti, posmatrano na ukupnom planu, po privrednim delatnostima i grupama preduzeća. Povoljnijim ostvarenjima privrede doprinosila je i Narodna banka Srbije po osnovu relaksacije monetarne politike i obezbeđenja relativno stabilnog kursa dinara, čime su preduzeća u Srbiji u velikoj meri rasterećena od ključnih finansijskih rashoda – troškova kamata i negativnih kursnih razlika. U prilog očuvanja ostvarenih rezultata u proteklim godinama govori i činjenica da je srpska privreda, i u uslovima zdravstvene i ekonomske krize bez presedana, prošlu godinu završila sa uvećanim poslovnim i finansijskim dobitkom.
