No âmbito escolar, entender de políticas públicas torna-se obrigatório, pois constantemente gestores e educadores são surpreendidos por políticas educacionais que regem toda a estrutura escolar. Com isso, são necessárias reflexões e discussões sobre a construção, abordagem e implementação de tais políticas nas escolas públicas. Nesse cenário, um grupo de professores universitários, pesquisadores e professores em atuação na educação básica está elaborando um material didático destinado ao ensino e aprendizagem de matemática, que esteja em consonância com a Base Nacional Comum Curricular (BNCC) e o Novo Ensino Médio (NEM). Assim, o objetivo desse texto é apresentar reflexões realizadas ao elaborar dois capítulos desse material e discutir alguns dos princípios norteadores e características gerais de dois capítulos do referido material. Um dos capítulos é destinado ao ensino e aprendizagem de projeções cartográficas e o outro a introdução ao pensamento computacional no ensino médio. Quanto ao pensamento computacional, destaca-se que da forma como está proposto neste momento, a BNCC privilegiou o aspecto algorítmico desse pensamento nas habilidades descritas e limitou a sua presença na área de Matemática e suas Tecnologias. Observa-se que o mesmo ocorre com o ensino de Projeções Cartográficas, que conforme a BNCC deve ser responsabilidade dos professores de Matemática. Visto que tanto a base quanto o NEM são realidades impostas, as reflexões apontadas no texto discutem as implicações da inclusão desses objetos do conhecimento no encargo da disciplina de Matemática. Além disso, apresentam-se atividades para que os professores de matemática consigam dar conta dessas novas demandas.

Published: March 2021

The summarized results of special tests of the Mi-2MSB helicopter equipped with the experimental system of 12,7 mm small arms (as a part with series-produced machine guns NSVT-12,7) and the serial system of unguided missile armament (NAR type C-8) are presented. The actual volume of assessments of inspections and work performed during the tests is given.
According to the results of processing the test materials, it was determined that the tactical range of the Mi-2MSB helicopter with the installed weapons system and boxes for collecting spent units (in the design provided for testing) at a takeoff mass of 3700 kg, at an altitude of not more than 300 m during combat mission in the area of the target for 5 minutes and the remaining fuel on the landing of 100 liters is (not less):

version of combat equipment 2 × B8V8MSB (payload - 16 NAR) - 190 km;
version of combat equipment 2 × NSVT-12.7 (payload - 600 rounds) - 200 km;
version of combat equipment 2 × B8V8MSB + 2 × NSVT-12.7 (payload - 16 NAR and 600 rounds) - 155

The results of special tests practically showed that the Mi-2MSB helicopter, equipped with an aviation weapon system, in addition to the functional tasks defined for the basic Mi-2MSB helicopter, is able to provide:

training and maintenance of skills for flight crew in the practical application of unguided aviation weapons and gun armaments in all types of maneuvering, defined by the tactics of army aviation;
accomplishment of certain tasks on air support of columns of troops on the march and fire missions on destruction of enemy manpower, single unarmored and lightly armored targets such as car, armored personnel carrier, infantry fighting vehicle, boat,

The main combat and functional capabilities in the actual operating conditions confirmed by the results of special tests as well as their validation of specified requirements make it possible (after eliminating the shortcomings identified in the test), to allow operation of Mi-2MSB helicopter in the entire operating range of heights and speeds equipped with aircraft weapons as part of the unguided missile system (NAR type C-8) and small arms system (as part of the series-produced machine guns NSVT-12.7)).

Published: March 2021

According to the experience of hostilities, including during the JFO (ATO), today much attention is paid by military experts to the development and improvement of optical and optoelectronic devices. This is due to the continuous improvement and development of new generation weapons systems that have improved tactical and technical characteristics, reduces the time spent by objects in the area of detection and damage, reduces the visibility of objects, increases their protection from interference and countermeasures, changes their tactics.
The main advantages of optoelectronic devices are: the secrecy of their use, in contrast to radar and radio equipment, they do not require additional systems of protection against interference; relative simplicity of design, operation and small dimensions; low energy consumption; ecological purity.
The current state of threats to Ukraine's sovereignty and territorial integrity, first of all the ongoing aggression of the Russian Federation, requires the introduction of necessary ways to counter them, improving approaches to the formation of military-technical policy, taking into account the urgent need to update existing weapons and military (special) equipment.
There is a need to create electron-optical transducers or matrix devices of other types that work in the visible and infrared ranges, for night vision devices, and opto-electronic systems for detection (registration) of laser radiation of rangefinders, control systems for homing projectiles, missiles in the optical range spectrum.
The paper describes the areas of improvement of optoelectronic means of surveillance, detection and aiming in order to increase the effectiveness of combat employment of armored weapons. The relevance of the study lies in the need to introduce fundamentally new concepts for the integration of optical and optoelectronic devices.

Inspection of armament and military equipment (AME) for the quality of manufacture and purpose tasks performance is carried out exclusively through testing. Tasks of conducting tests within the framework of ensuring the implementation of State programs for equipping the Armed Forces of Ukraine with modern armament and military equipment require proper instrumentation of the laboratory and test base of the Armed Forces of Ukraine, which is necessary to determine during tests numerical indicators of technical and operational characteristics in accordance with requirements of state standards parallel to standards of world’s major economies to evaluate new, upgraded armament, armament with service life extension and procured armament.
During the study, general scientific methods of information processing and systematization were used, in particular system analysis and synthesis of organizational and technical systems.
The purpose of the article is to improve the quality of testing of new and modernized pieces of AME by developing general requirements for a thermal pressure chamber.
A study was conducted to substantiate the composition of the thermal pressure chamber, its main tasks, objects of action, capabilities, conditions of application, requirements for interaction with control systems or other objects with which the system is combined. Based on the analysis, the article proposes general requirements for a thermal pressure chamber, which will improve the quality of testing of new and upgraded pieces of AME; reduce material and technical expenditures and reduce the time of AME testing.

Abstract
We present the first results from the Mapping Obscuration to Reionization with ALMA (MORA) survey, the largest Atacama Large Millimeter/submillimeter Array (ALMA) blank-field contiguous survey to date (184 arcmin2) and the only at 2 mm to search for dusty star-forming galaxies (DSFGs). We use the 13 sources detected above 5σ to estimate the first ALMA galaxy number counts at this wavelength. These number counts are then combined with the state-of-the-art galaxy number counts at 1.2 and 3 mm and with a backward evolution model to place constraints on the evolution of the IR luminosity function and dust-obscured star formation in the past 13 billion years. Our results suggest a steep redshift evolution on the space density of DSFGs and confirm the flattening of the IR luminosity function at faint luminosities, with a slope of

. We conclude that the dust-obscured component, which peaks at z ≈ 2–2.5, has dominated the cosmic history of star formation for the past ∼12 billion years, back to z ∼ 4. At z = 5, the dust-obscured star formation is estimated to be ∼35% of the total star formation rate density and decreases to 25%–20% at z = 6–7, implying a minor contribution of dust-enshrouded star formation in the first billion years of the universe. With the dust-obscured star formation history constrained up to the end of the epoch of reionization, our results provide a benchmark to test galaxy formation models, to study the galaxy mass assembly history, and to understand the dust and metal enrichment of the universe at early times.
On the Origin of Hard X-Ray Emissions from the Behind-the-limb Flare on 2014 September 1

Abstract
The origin of hard X-rays and γ-rays emitted from the solar atmosphere during occulted solar flares is still debated. The hard X-ray emissions could come from flaring loop tops rising above the limb or coronal mass ejection shock waves, two by-products of energetic solar storms. For the shock scenario to work, accelerated particles must be released on magnetic field lines rooted on the visible disk and precipitate. We present a new Monte Carlo code that computes particle acceleration at shocks propagating along large coronal magnetic loops. A first implementation of the model is carried out for the 2014 September 1 event, and the modeled electron spectra are compared with those inferred from Fermi Gamma-ray Burst Monitor (GBM) measurements. When particle diffusion processes are invoked, our model can reproduce the hard electron spectra measured by GBM nearly 10 minutes after the estimated on-disk hard X-rays appear to have ceased from the flare site.
Evaluation of the Panbio Leptospira IgM ELISA among Outpatients Attending Primary Care in Southeast Asia

Published: March 2021

ABSTRACTDespite estimates suggesting Leptospira spp. being endemic in Southeast Asia, evidence remains limited. Diagnostic accuracy evaluations based on Leptospira ELISA mainly rely on hospitalized and severe patients; therefore, studies measuring the pathogen burden may be inaccurate in the community. We evaluated the Panbio Leptospira ELISA IgM among 656 febrile outpatients attending primary care in Chiangrai, Thailand, and Hlaing Tha Yar, Yangon, Myanmar. ELISA demonstrated limited diagnostic accuracy for the detection of acute leptospiral infection using the manufacturer recommended cutoff, with a sensitivity of 71.4% and specificity of 36.4%, and an area under the receiver operator characteristic curve value of 0.65 (95% CI: 0.41–0.89), compared with our reference test, the PCR assay. ELISA also performed poorly as a screening tool for detecting recent exposure to Leptospira spp. compared with the “gold-standard” microscopic agglutination test, with a specificity of 42.7%. We conclude that the utility of the Leptospira IgM ELISA for both serodiagnosis and seroprevalence is limited in our setting.

Authors: Kvach Elizabeth J. , Weinand Jamie , O'Connell Ryan 
Published: March 2021

ABSTRACT

Background
Increasing numbers of transgender and nonbinary (TNB) people seek careers in medicine, but little is known about their experiences and the effect of their gender identity during residency application.

Objective
This project sought to evaluate the experiences and needs of TNB individuals during the residency application and Match process in order to inform the practice of residency programs.

Methods
An online survey was distributed in 2019 via social media, professional groups, and snowball sampling to TNB persons, who were current residents or recent graduates (within the past 3 years) of a US residency program.

Results
Twenty-six eligible respondents from 10 medical specialties completed the survey. Eighteen (69.2%) respondents felt unsafe disclosing their gender identity or discussing it during interviews some or all of the time due to fear of discrimination and how it might affect their match; 26.9% (7 of 26) felt they were ranked lower than their qualifications due to their gender identity. Eleven (42.3%) were misnamed or misgendered some or all of the time during interviews through use of incorrect name and pronouns. Respondents' recommendations for programs included: (1) adopt gender-affirming practices; (2) offer gender-affirming health benefits; (3) advertise nondiscrimination policies; (4) understand experiences of discrimination during medical training; and (5) value resident gender diversity.

Conclusions
TNB residents and recent graduates perceived gender identity discrimination during residency application, including feeling unsafe to disclose their gender identity and being misnamed or misgendered. Suggestions for programs to improve the experience of TNB applicants are included.

Published: March 2021

Studies have attributed project failure to poor communication management. This research assessed the impact of communication management on the delivery of construction projects in Abuja, with a view to proposing strategies for improving communication management. The quantitative research method was adopted for the study. Data collection was done through questionnaire survey. Analysis of data was carried out using Mean Item Score (MIS) and Relation Importance Index (RII). Results of the study revealed that the most important causes of poor communication management on construction projects range from Poor feedback (RII = 0.89) to Lack of training (RII = 0.82). The influence of communication management on the cost (MIS = 3.80-4.55), time (MIS = 3.83-4.50) and quality (MIS = 3.53-4.25) delivery of construction projects is significant. Based on these findings, it was concluded that the impact of communication management on the delivery of construction projects in Abuja is significant. It was recommended that project managers should avoid the major causes of poor communication management which range from “Ineffective communication channel used” to “Lack of training” in order to minimise potential dispute, misunderstanding and project failures as a result of poor management of communication on project sites.

In the 21st century, from bank to insurance, multinational companies to government offices have increased thousands of times their profitability, productivity, sustainability, and also market expansion through the successful uses of ICT. Today another aspect is the preparation of a high-quality financial report that relies entirely on the information. Quality information depends on several characteristics like completeness, accuracy, timeliness, consistency, validity, accessibility, and integrity of that information, etc. Having these characteristics in financial information is the prerequisite for good financial reporting. Usages of IT have a great role in producing quality information and financial reporting consequently. The use of IT in the banking sector is more sophisticated than in other sectors in Bangladesh. Therefore, the purpose of this research is to examine analytically the relationship between the use of Information Technology and the quality of financial reporting. Using primary data sourced a structured questionnaire was administered to selected banks in Bangladesh and data analysis was done through the General Regression Model by OLS method to examine the nature of the relationship that exists between the quality of financial reports and the Adoption of Information Technology. The result of the data analysis of the study showed that a positive correlation exists between IT and the quality of reports.
