Published: July 2021

O crescente aumento de consumo energético em edificações é uma questão preocupante. O modo como as edificações se comportam em relação ao clima em que estão inseridas é importante no seu consumo final, e assim, diretrizes iniciais de projeto voltadas ao seu comportamento térmico podem reduzir boa parte do consumo durante a operação. Isso porque essas diretrizes visam otimizar o desempenho das edificações, minimizando o uso de equipamentos de resfriamento para garantir o conforto dos usuários. No entanto, essas análises de desempenho térmico são realizadas com o projeto já consolidado, dificultando o alcance de bons níveis de desempenho e sem grande margem de alteração de projeto com este foco. Visando unir o processo a essas análises, o objetivo deste trabalho é o levantamento de dados sobre o processo de projeto de arquitetos para compreender quais parâmetros de desempenho já são considerados, quais outros poderiam ser incorporados, e quais as fases de maior relevância do ponto de vista térmico. Percebeu-se que os participantes deste estudo, apesar de considerarem relevante a avaliação de critérios como insolação e ventilação natural na concepção de projeto, o fazem com métodos pouco precisos. Além disso, evidenciou-se o desconhecimento de aspectos importantes, como a NBR 15575, a etiqueta de eficiência energética e o uso de simulações computacionais. Portanto, propõe-se uma estrutura de trabalho integrando as respostas sobre definições de projeto com os critérios de análise de desempenho. O desenvolvimento de uma estrutura de trabalho permitirá futuros experimentos de inserção de simulações no processo de projeto para validação.

Brincando na educação infantil − ensinar e aprender com retóricas lúdicas
Authors: Gomes Cleomar Ferreira
Published: July 2021

O ensaio em tela é fruto de uma investigação sobre retóricas lúdicas, narradas por professoras no cotidiano da Educação Infantil. Com um questionário semiestruturado, aplicado em seus loci de trabalho, identificamos a noção que as professoras têm de brincadeiras, o método que utilizam para atividades lúdicas no ambiente escolar, bem como as narrativas que organizam tais atividades, para algum resultado positivo na educação de crianças pequenas. Supomos apropriado considerar aquilo que alguns teóricos dos termos brinquedos e brincadeiras relevam como válidos pela pena da ciência. Foi muito rico para pesquisadores e professoras saber como elas lidam com esses conceitos e como aproveitam esses conhecimentos adquiridos nos cursos de formações específicas e estudos para, na intervenção, auferir algum resultado prático. Formulamos algumas questões que pudessem cercar esses conhecimentos no modus operandi de cada uma dessas professoras. As respostas revelaram que os discursos são favoráveis à entrada de brinquedos, jogos e brincadeiras no espaço escolar porque estimulam o curso natural do desenvolvimento das crianças. De modo particular, foi possível analisar as formas de envolvimento e as intervenções naquilo que narram como percepções, noções e mesmo intervenções pedagógicas, que melhor representam as funções estéticas e pedagógicas das brincadeiras e dos brinquedos quando se subsumem nos espaços de escolarização.

Authors: Fernandes Solange Jarcem , Alves Andrêssa Gomes de Rezende , Viana Elayne Silva
Published: July 2021

Este trabalho analisou a relação público-privada entre o município de Campo Grande, MS, e a Sociedade Caritativa e Humanitária (Seleta) em relação aos convênios firmados no período de 1997 a 2016. A parceria teve como objeto a prestação de serviços socioeducativos para preservação e ampliação das ações de atendimento à criança e ao adolescente em regime de cooperação com a Secretaria Municipal de Educação (SEMED). Esses convênios foram encerrados em dezembro de 2016, quando o Ministério Público do Estado de Mato Grosso do Sul (MPMS) impetrou uma Ação Civil Pública que culminou com a demissão de trabalhadores que prestavam serviços nos Centros de Educação Infantil (CEINFs). Como procedimento metodológico, foram realizadas consultas à legislação educacional em âmbito federal e municipal, aos documentos produzidos pelo município de Campo Grande, MS, aos documentos do MPMS e do TJMS e à literatura da área. Conclui-se que as transferências das ações estatais para uma entidade de caráter privado alteraram a responsabilidade do município em realizar concurso público para a contratação de trabalhadores para atuar nos CEINFs, ferindo-se o artigo 37 da Constituição Federal de 1988, pois não foi observado o caráter de excepcionalidade previsto na Constituição Federal de 1988.

Published: July 2021

O presente artigo tem o objetivo de explorar diferentes conceitos acerca dos termos governança, governação e governabilidade, inseridos em uma perspectiva de influência dos modos de gestão. Busca-se aqui apresentar conceitos influenciadores da gestão escolar, assim como contrapor à ideia de surgimento de um novo modelo de gestão das escolas estaduais de Santa Catarina (SC). Após a conceitualização desses termos, apresenta-se a organização escolar por meio da adesão a um modelo de governança com raízes na administração empresarial. Destacam-se, nas análises, diferentes interpretações do conceito de governança, sendo uma delas utilizada para representar o modo de gestão aplicado nas escolas estaduais de SC como um modelo participativo e democrático. Por fim, apresentam-se no artigo as legislações e os decretos que resultaram na implementação desse novo modelo, juntamente de uma breve análise de textos e da conjuntura em que ocorreu a implementação. Para as conclusões deste estudo, destaca-se que, apesar de a gestão escolar caminhar para rumos democráticos por meio de legislações e teorias, a prática ainda ocorre nos velhos moldes centralizados e hierárquicos, em que o novo modelo de governança nada mais é que a reestruturação da velha organização escolar.

Authors: Souza Elizeu Clementino de , Pinho Ana Sueli Teixeira de
Published: July 2021

O texto objetiva estabelecer relações entre o acolhimento às diferenças e temporalidades dos sujeitos, observando implicações curriculares daí emergentes e seus efeitos na constituição do tempo escolar. Do ponto de vista metodológico, adotaram-se princípios da pesquisa (auto)biográfica e a entrevista narrativa como dispositivo de pesquisa. No modelo curricular, ainda vigente, a expectativa é de que o sujeito internalize formas de controle do tempo, a fim de convertê-lo num corpo dócil e previsível, em relação a suas ações, de modo que todos se tornem parecidos, apesar de suas diferenças. Destacamos, como resultado da pesquisa, a necessidade de as políticas curriculares considerarem a reação do outro, que não se submete a um modelo curricular pronto, baseado na imposição de uma sincronização, com a justificativa de socialização, de inserção no mercado, de preparação para a vida e necessidade de acolhimento às diferenças e suas temporalidades, a fim de garantir a oportunidade de pensar a educação, a partir da coexistência e interação da diferença.
The stereotypical representation of women in the classic fairy tales Snow White, Cinderella, and Sleeping Beauty
Authors: Berlianti Anisa Dyah
Published: July 2021

The stereotype that emerges from some classic fairy tales is a princess who has a beautiful face and an angelic heart, a prince on a white horse who is handsome and charming, and a happy ending forever. These three sweet things are generally always the main menu served in bedtime fairy tales, including the classic fairy tales Snow White, Cinderella, and Sleeping Beauty. Besides sounding beautiful, the plot and characterization presented in the classic fairy tale represent a woman through feminine standards packaged through stereotypes. This research uses qualitative research methods and narrative analysis. The research results found details of the seven functional characters of the characters in the fairy tale. It can then be seen that various stereotypical representations aimed at women in the three tales, ranging from the obsession with natural beauty, misconceptions about the meaning of ambition, and marriage, are the solution for all the problems of a woman.
RISK FACTORS FOR PREMATURE BIRTH IN INDONESIA
Authors: Sukma Hafiza Ajeng Dianing , Tiwari Sagar
Published: July 2021

Indonesia is currently taking on the challenge of the relatively high number of neonatal deaths influencing maternal and child health. Premature birth is the most significant contributor to the number of neonatal deaths. The occurrence of premature birth is motivated by various risk factors. Knowing the magnitude of the relationship between several risks, namely maternal age, location, parity, and maternal smoking habits with preterm birth incidents was the aim of this study. The 2017 Indonesian Demographic and Health Survey (IDHS) was a source of data used. This study employed a cross-sectional approach and then processed the results with univariate and bivariate tests. The results showed a relationship between maternal age and residential area with the premature birth, where mothers under 20 years and over 35 years had a higher probability of giving birth prematurely. The area of residence, which was divided into rural and urban, also had a relationship with premature birth. The parity and smoking habits showed no association with preterm birth. Education, Antenatal Care (ANC), and other various efforts to emphasize maternal and child health care during pregnancy need to be continuously improved to reduce preterm birth rates in Indonesia.

ANALYSIS OF FACTORS INFLUENCING THE INTENSITY OF TRANSFORMER OIL AGEING IN LONG-TERM OPERATION
Authors: Ponomarenko Serhii
Published: July 2021

The results of the analysis of influence of operational factors and peculiarities of transformer design on intensity of oxidative reactions of transformer oils in the tanks of 110 kV high-voltage power transformers are presented. As a result of two-way analysis of variance it was found that with increasing operating time there is a statistically significant increase in the value of the organic acid content in the oil. At the same time the rate of increase in the organic acids content in the transformer oil, operated under different conditions, significantly differs, which indicates a significant influence of operating conditions on the intensity of oxidative reactions. The results of two-way analysis of variance also show that the effects of changes in factor levels are not additive, that is, the effect of a change in the level of influence of one factor leads to a change in the effect of the level of influence of another. In other words, the process of oil oxidation is cumulative and a certain level of organic acids in the oil can be achieved either over a longer period of operation, but with relatively 'light' operating conditions, or over a shorter period of time, but with more 'heavy' operating conditions. In order to determine the factors most affecting the intensity of oxidative reactions, an analysis of the quality of filled oil, operating time, the influence of the region, the influence of the type and nominal characteristics of transformers on 6 data sets with identical rates of oxidative reactions was carried out. The results of the analysis show that the intensity of oxidation reactions is strongly influenced by the operating time, the transformer loading factors, the consumer composition (region of Ukraine) as well as the type and quality of oils. At the same time, factors such as rated capacity, type of transformer, number of windings, and the value of rated voltage on the medium and low voltage windings do not influence the intensity of oxidation of oils. The results obtained allow the correction of the maximum permissible values of oil acidity, taking into account the factors affecting the intensity of oxidation of oils.
DEVELOPMENT AND MODELLING OF HIGH SPREAD CONDUCTIVITY EARTH ELECTRODES FOR COMPLEX EARTHING ARRANGEMENTS
Authors: Balalaiev Vyacheslav , Fedoseenko Olena
Published: July 2021

The analysis of methods for calculating the electrical characteristics of earth electrodes in case of emergency currents of industrial frequency flowing through the elements of earthing arrangements is carried out. A method for improving complex earthing arrangements of electrical installations by optimization of their design parameters is proposed. The proposed method consists in installing an artificial earth electrode with an increased contact area of its surface with the ground, which makes it possible to increase the conductivity of earthing spreading. The use of these electrodes on the territory of projected or operating electrical installations ensures that the values of the normalized parameters of earthing arrangements are brought to permissible values. The use of the method given in the calculations of earthing arrangements requires the replacement of volumetric earth electrodes with a set of linear vertical electrodes. The design model is substantiated by equivalent electrical characteristics relative to the two-layer model of the electrical structure of the earth. The equivalent model was obtained by a given approximation of the electrical characteristics of a set of straight electrodes in the process of increasing their number to the equivalent characteristics of the reference model. In turn, the determination of the characteristics of the reference model was carried out directly by solving the boundary value problem for the potential satisfying Laplace equation using finite difference method. Theoretical investigations using induced potential method and methods of calculation of branched electric circuits with distributed parameters for calculation of electric field and resistance of the complex non-equipotential earth electrode in the ground with two-layer structure have been carried out. The developed electrodes of increased spread conductivity are mounted as experimental samples and are involved in the formation of the electrical characteristics of the earthing arrangements.
CORRECTION OF THE METHOD FOR MEASURING THE AMPLITUDES OF THE CURRENT OF THE IMPULSE ALONG THE LONG EARTH ELECTRODE
Authors: Nizhevsky Viktor , Berezka Sergey , Fedoseenko Olena , Nizhevsky Ilia
Published: July 2021

An improved method for measuring the amplitude reduction of the lightning current impulse as it flows from the beginning to the end of long horizontal earthing arrangement using ferromagnetic recorders has been substantiated. Two existing methods of pulse amplitude measurements at high voltages, the magnetic recording method and the method using a shunt, are used in justification. It is noted that in a number of cases it becomes necessary to determine the decrease in the pulse amplitude as it flows on a long object. This leads to the need to develop a method for performing such measurements. As an example, a long horizontal earth electrode was investigated when a lightning current pulse moves on it. Based on experimental studies in natural conditions, an improved method for measuring the decrease in the amplitude of the lightning current impulse along a long earth electrode is proposed. The proposed method has a measurement error not exceeding 10 %, and allows simultaneous measurements of the amplitude of the current strength at given points of the object, which can amount to tens or even hundreds. This method is implemented in a simple design and has an affordable manufacturing cost. The results of the experiments performed make it possible to recommend the corrected measurement method for practical use on existing electrical installations. The use of ferromagnetic recorders for recording and measuring the lightning current in areas of complex earthing arrangements is relevant for practical reasons, which include the possibility of measuring during a long wait and long-term storage of measurement results, does not require additional power sources and provides the possibility of synchronous measurements at various points of the grounding device. An important feature of the method is safety for technical equipment and personnel.
DEVELOPMENT OF A MEASUREMENT SYSTEM AND SOFTWARE PRODUCT TO COLLECT AND ANALYSE ELECTRICITY QUALITY PARAMETERS
Authors: Nikonov Nikolay Sergeevich , Borzenkov Igor Ivanovich , Lebedinsky Igor Leonidovich
Published: July 2021

In the real operating conditions of electrical networks, there are modes of operation characterised by deviations of their parameters from their nominal values. Of particular importance for the operation of electrical equipment are variations in the amplitude and frequency of the supply voltage. The permissible and limit deviations of these parameters are regulated in accordance with national standards. To calculate the main power quality parameters it is not sufficient to know only the methods of their calculation. Additional algorithms are needed to determine fundamental harmonic voltages and frequencies. Such a method is the discrete Fourier transform. This algorithm is designed for signal analysis. However, this algorithm was not widely used in calculating Fourier coefficients in modern software packages. The reason is that it takes much time and computer resources to determine the Fourier coefficients which reduces the attractiveness of this approach. For this reason, it is advisable to use the fast Fourier transform algorithm. This algorithm uses the periodicity properties of the trigonometric function, which allows reducing the number of multiplication operations. The results of using the fast Fourier transform algorithm are similar to the discrete Fourier algorithm, but the number of operations required for calculation is several times less. At the same time, fast and discrete Fourier transform algorithms can give quite a significant error in determining the frequency estimate. This deviation is related to multiplicity of time between signal measurements and its period. If the period of the analogue signal is a multiple of the sampled signal measurement distance, an additional Quin method must be used to reduce the error in determining the frequency of the main signal. In this regard, the development of algorithms and software complex for automated measurement systems of electrical power quality indicators using digital data acquisition and processing devices in real time is an urgent task.

Contratação integrada: o (des)alinhamento do regime a boas práticas internacionais
Authors: Forni João , Cavichioli Carmona Paulo
Published: July 2021

A contratação integrada é um novo regime de execução de obras e serviços de engenharia que integra as responsabilidades pela elaboração do projeto básico e pela execução da obra, em oposição ao modelo tradicional, presente na Lei n. 8.666/1993, que separa essas duas atribuições. A utilização desse regime tem se expandido com base em certos pressupostos, entre eles o alinhamento a boas práticas internacionais. O presente trabalho, por meio de revisão bibliográfica, pesquisa em atos normativos e análise de estudos empíricos objetiva testar esse pressuposto, demonstrando que a alusão à experiência internacional, especialmente ao design-build norte-americano, padece de fragilidades, tanto conceituais quanto relacionadas a requisitos de utilização. Além disso, modelos similares à contratação integrada ou são usados de maneira excepcional (Portugal); ou foram abandonados (Itália); ou envolvem requisitos mais rigorosos (França) em relação aos impostos pelo ordenamento brasileiro.
Rudist bivalves (Hippuritoidea) from the Clifton Limestone (Lower Campanian) of western Jamaica and a reassessment of the genus Vaccinites in the Americas
Authors: Mitchell Simon F.
Published: July 2021

The lower Campanian (Upper Cretaceous) Clifton Limestone of Jamaica yields three species of hippuritid bivalve: Barrettia ruseae CHUBB, Whitfieldiella luceae sp. nov. and Vaccinites vermunti MAC GILLAVRY, and the plagioptychid: Plagioptychus sp. The hippuritids are described in detail using statistics. Barrettia ruseae is demonstrated to be a more primitive species of Barrettia than B. monilifera WOODWARD or B. multilirata WHITFIELD, and the species Whitfieldiella luceae is shown to be a more primitive species of Whitfieldiella than W. gigas CHUBB. The specimens of Vaccinites from the Clifton Limestone are compared with populations of Vaccinites from elsewhere in the Americas, and five species (probably representing a single evolutionary lineage) are recognized: V. alencasteri sp. nov. (?late Turonian-?Coniacian), V. martini MAC GILLAVRY (probably early to mid Santonian), V. macgillavryi PALMER (probably mid to late Santonian), V. vermunti MAC GILLAVRY (earliest Campanian), and V. temazcali sp. nov. (late early Campanian). The Vaccinites species can be distinguished using statistical techniques. The ages of the Clifton Limestone and the five Vaccinites species are reviewed. This research demonstrates the value of using hippuritids for biostratigraphy in the Upper Cretaceous of the Americas.

The research objective to analyze the growth of the people's salt farming business using the geomembrane method compared to the traditional method to describe the impact of innovation on business sustainability and to explore the sustainability of the people's salt farming business from the perspective of internal stakeholders based on stakeholder theory. The research used a case study approach configurative ideographic studies as a research method. This study concludes that people's salt farming business know the geomembrane of the PUGAR program. The growth rate of using geomembranes is more profitable than using traditional methods, but only a part of farmers' land uses geomembranes because of the inability of capital and the break even point which becomes high due to unstable selling prices. People's salt farming entrepreneurs still have difficulty accessing credit from the government so that some still depend on accounts payable with traders/middlemen for capital. The salt from people's salt farming business is not purchased by PT. Garam because the quality is still not up standard. The CSR received by the community from PT Garam is in the form of social activities, not in the form of activities that support people's salt farming business. For informants of this study, the level of sustainability of people's salt farming business is still high, because salt farming is currently more productive than other farms.

Study on Fracture Characteristics and Controlling Factors of Tight Sandstone Reservoir: A Case Study on the Huagang Formation in the Xihu Depression, East China Sea Shelf Basin, China
Authors: Zhao Zhongxiang , He Youbin , Huang Xin
Published: July 2021

Natural fractures are not only the key to affect the natural productivity of tight sandstone reservoirs but also one of the important factors to control the fracturing effect. If the local strata are affected by multistage tectonic movement and diagenesis, it will lead to the complexity of fracture types and characteristics, which makes it difficult to accurately identify natural fractures, thus, seriously affect the development of fractured reservoirs and the fracturing effect. In this paper, the macroscopic fractures were studied by combining core, conventional logging, imaging logging, petrophysical logging, logging, drilling, and gas test data. The microscopic fractures were analyzed by casting thin sections and scanning electron microscopy and cathodoluminescence. The effect of fractures on hydrocarbon migration was analyzed by fluid inclusions in fractures. The core can be used to visually study the opening fracture, but when the color of the filling inside the fracture is similar to the surrounding, the filling fracture is not easy to be found. Imaging logging has high identification accuracy for filling fractures, but it can hardly be used as a means of identifying high-angle opening fractures. The opening fracture zone in the noncoring section can be studied by conventional logging, mud logging, drilling, and rock mechanical parameter. The macroscopic structural fractures are obviously directional, which is controlled by the tectonic stress field. The occurrence and density of macroscopic structural fractures are controlled by buried depth, lithology, rock thickness, sedimentary facies, distance from the fault, and structural location. The opening fractures are all of high angle, indicating that the inclination angle is an important factor affecting the filling degree of fractures. The direction of intragranular fractures is chaotic, which is affected by the mechanical weak surface of the mineral particles, particle morphology, and particle contact relationship and stress. Effective fractures provide channels for the migration of oil and gas and acidic fluids in the historical period, which promote the occurrence of hydrocarbon accumulation and dissolution.

Loss of the vast majority of heat and steam is an unavoidable problem encountered during conventional steam-assisted gravity drainage (SAGD) in extraheavy oil reservoirs. The noncondensate gas coinjection technique of reducing energy consumption and enhancing oil recovery can effectively solve this problem. Aiming at extraheavy oil with a high initial viscosity, the influence of noncondensate gases in multithermal fluids on the physical parameters of extraheavy oil was experimentally studied; the production characteristics and mechanism of multithermal fluid-assisted SAGD were studied through numerical simulation. A comparative investigation of the conventional SAGD and multithermal fluid-assisted SAGD injection schemes was conducted. The characteristics and mechanism of the steam chamber during the production processes were analyzed. The results show that a steam-gas-oil system forms in the steam chamber in the case of multithermal fluids. The steam chamber can be partitioned into four zones, and the flow of the oil mainly occurs in the steam condensation zone and the oil drainage zone. The injected multithermal fluids increase the horizontal expansion of the steam chamber, while the dissolved carbon dioxide reduces the residual oil saturation. Moreover, the nitrogen injection significantly reduces the heat loss and increases the heat utilization for multithermal fluid-assisted SAGD in developing extraheavy oil reservoirs.

Computational oral absorption models, in particular PBBM models, provide a powerful tool for researchers and pharmaceutical scientists in drug discovery and formulation development, as they mimic and can describe the physiologically processes relevant to the oral absorption. PBBM models provide in vivo context to in vitro data experiments and allow for a dynamic understanding of in vivo drug disposition that is not typically provided by data from standard in vitro assays. Investigations using these models permit informed decision-making, especially regarding to formulation strategies in drug development. PBBM models, but can also be used to investigate and provide insight into mechanisms responsible for complex phenomena such as food effect in drug absorption. Although there are obviously still some gaps regarding the in silico construction of the gastrointestinal environment, ongoing research in the area of oral drug absorption (e.g. the UNGAP, AGE-POP and InPharma projects) will increase knowledge and enable improvement of these models. PBBM can nowadays provide an alternative approach to the development of in vitro–in vivo correlations. The case studies presented in this thesis demonstrate how PBBM can address a mechanistic understanding of the negative food effect and be used to set clinically relevant dissolution specification for zolpidem immediate release tablets. In both cases, we demonstrated the importance of integrating drug properties with physiological variables to mechanistically understand and observe the impact of these parameters on oral drug absorption. Various complex physiological processes are initiated upon food consumption, which can enhance or reduce a drug’s dissolution, solubility, and permeability and thus lead to changes in drug absorption. With improvements in modeling and simulation software and design of in vitro studies, PBBM modeling of food effects may eventually serve as a surrogate for clinical food effect studies for new doses and formulations or drugs. Furthermore, the application of these models may be even more critical in case of compounds where execution of clinical studies in healthy volunteers would be difficult (e.g., oncology drugs). In the fourth chapter we have demonstrated the establishment of the link between biopredictive in vitro dissolution testing (QC or biorelevant method) PBBM coupled with PD modeling opens the opportunity to set truly clinically relevant specifications for drug release. This approach can be extended to other drugs regardless of its classification according to the BCS. With the increased adoption of PBBM, we expect that best practices in development and verification of these models will be established that can eventually inform a regulatory guidance. Therefore, the application of Physiologically Based Biopharmaceutical Modelling is an area with great potential to streamline late-stage drug development and impact on regulatory approval procedures.

Object of research: Soil samples contaminated with radionuclides and processes for treatment of contaminated soil.

The problem to be solved: Isolation of radionuclides from contaminated soil samples by extraction with weak solutions of acids and alkalis.

Main scientific results: Treatment of soil samples contaminated with uranyl nitrate using extraction with weak solutions of nitric and hydrochloric acid, caustic sodium and subsequent washing of soil residues with distilled water is effective process and leads to a more than tenfold decrease in the content of uranium isotopes (U238, U235, U234 and U236) in the soil samples. At the same time, there is a decrease in the content of natural radionuclides (Na22, K40, Zn65, Sn113, Sn126) in the extracted soil samples. An increase in their content in the extract of the analyzed soil samples corresponds to a decrease in their content in the residue of the extracted soil samples. The analysis of the values of the decrease in the content of natural radionuclides in the soil contaminated with uranyl nitrate corresponds to the values of the decrease in their content in the identical soil, but not contaminated with uranium isotopes. The combined extraction with weak solutions of acids and alkalis leads to the enrichment of the soil with nitrates and chlorine-containing compounds.

The area of practical use of the research results: Subdivisions of the Ministry of Emergency Situations and Chemical Troops specializing in the study of emergencies and natural disasters can use the results of these studies in the elimination of the consequences of global environmental disasters and incidents that pose a threat to the life of the civilian population and the personnel of paramilitary units.

Innovative technological product: The proposed method for treatment of soil contaminated with radionuclides makes it possible to more than tenfold reduce their concentration in the soil.

Scope of application of an innovative technological product: treatment of contaminated soil in areas affected by nuclear tests or accidents at nuclear power plants.

Partner Notification Service (PNS) Has Been A Long-Standing Component Of The HIV/AIDS Control Programs And A Keep Part Of The Innovative Approaches To Achieve Epidemic Control. Many Programs Around The World And Facilities, Especially In Nigeria, Have Been Scaling Up The Strategy. The Study Reviewed The Activities Of Partner Notification Services In The University Of Abuja Teaching Hospital, Abuja, Between January 2019 And December 2019. A Retrospective Cohort Analysis Of Client’s Folders, Registers, And The Electronic Medical Record Was Done. A Total Of 451 Clients With HIV Infection (194 New Positives And 257 Virally Unsuppressed Clients) Were Interviewed. The Majority Of The Clients (86.2%) Accepted The Offer Of Partner Notification Service And Elicited 457 Partners (1: 1.2 Partners), 388 (84.9%) Were Notified Of Their Risk Of Exposure To HIV. Of The 323 Partners That Were Reached, 97 (30%) Previously Knew Their HIV-Positive Status, 62 (19.2%) Were Newly Diagnosed, And 164 (50.8%) Tested Non-Reactive. The Total HIV Testing Yield Was 3.8% (207 Positives From 5394 HIV Test Done), Index Testing Done Through Partner Notification Service Had The Highest Yield At 27.4%, Then Voluntary Testing And Counselling At 10.1%, Followed TB Clinic HTS At A Yield Of 2.9%. Other Testing Points Had A Yield Of ≤ 1 %. The Study Supports Many Other Similar Studies In Demonstrating The Effectiveness Of Partner Notification Service As A Key Strategy In Achieving Epidemic Control Of HIV/AIDS. It Is Also Effective In The Management Of Scarce Resources That Currently Plagues Many Developing Nations Like Nigeria.
