Purpose. To determine the thickness of thin films of coal matter in the Sherubaynurinsky area of the Karaganda basin and their effect on the physical properties of these films. Methodology. In order to calculate the thickness of the surface layer of the coal substance using our proposed formula, one needs to know the molar mass and density. We will use the well-known work where it is shown that such a characteristic as the molecular weight of coal reflects rather well the degree of metamorphism, and is also decisive for the study on the composition and structure of coal raw materials. Findings. The role of the thickness of the surface layer of coal in the course of most physical processes is shown. A thin layer of coal matter differs significantly from metals and other compounds. But it is close to the structure of higher fullerenes. One fundamental parameter, the atomic volume of the surface layer, determines all the properties of the nanostructure of this layer. Originality. For the first time, the thickness of the surface layer of the coal substance has been determined, which is two orders of magnitude greater than the thickness of pure metals. The thickness of the surface layer of higher fullerenes C96 (135 nm) is close to that for OC coal (146 nm). The average statistical structural unit of coal corresponds to higher fullerenes with the number of carbon atoms in the cluster >100, which is a unique feature of coal matter. The thickness of the surface layer of coal in the Sherubaynurinsky area of the Karaganda basin with a size of ~150200 nm was obtained. This structure is a nanostructure. In this layer, the physicochemical properties of nanomaterials occur: a change in the crystalline (supramolecular) structure of coal; a change in its electronic structure and its electrical conductivity; change in the conditions of the stress state of coal; change in the conditions of methane diffusion in coal seams and many other phenomena. Practical value. The natural gas content C0 depends linearly on the reciprocal of d(I). For coal seam k, where d(I) = 180.8 nm, it was obtained 0 = 19 m3/t. After the release of coal and gas, the average value of C0 = 216 m3/t at a seam depth of 430 m, and in the Sherubaynurinsky area C0 = 14 m3/t at an average thickness of the surface layer d(I) = 170 nm. Hence, after the explosion d(I)v = 35 nm, i.e. the layer thickness decreases by almost 5 times, leading to the formation of coal dust. We have considered only a part of the nanostructure issues: porosity and gas content, explosiveness and moisture content of coal seams, and have shown that all physical phenomena in a thin layer of coal have a dimensional dependence and determine structures unexplored until now, and phenomena studies on which are necessary for the practice of mining.

Purpose. Development of a technique for the numerical study on the decomposition of gas hydrate plugs in deep-water pipelines under microwave radiation using a coaxial source. Theoretical efficiency evaluation of using such an impact to unblock the pipelines. Methodology. Mathematical modeling and computational experiment. Findings. An original mathematical model is proposed to describe heat transfer processes during the decomposition of gas hydrates in a pipeline under the action of heat sources distributed over the volume. The non-stationary problem of heat transfer was considered in a one-dimensional formulation. An algorithm for numerical computation is proposed. A mathematical expression is obtained for distributed heat sources generated by the microwave radiation from a coaxially located SHF antenna. Parametric numerical studies on temperature fields and decomposition dynamics of a gas hydrate plug are performed for specified parameters of pipe and microwave radiation power. The boundaries of the decomposition area and the dynamics of change in this area are determined. The decomposition time of a gas hydrate plug with a diameter of 0.3 m was determined using a 300 W microwave source. The complete decomposition took approximately 40 hours. Originality. The task of thermal decomposition of a cylindrical gas hydrate plug in a pipeline due to microwave heating using a coaxial microwave power source has been considered for the first time. The process is viewed as a sequence of several stages: heating, heating and decomposition, decomposition after complete heating of the gas hydrate layer. To model the volumetric dissociation of gas hydrate, it was proposed to use special functions that characterize the amount of decomposed gas hydrate. The introduction of such functions makes it possible to construct an efficient computational algorithm taking into account the action of volumetric sources in the decomposition area. The known models mainly consider only surface thermal effect or microwave impact on gas hydrate in porous mediums. The presented model allows describing the decomposition during volumetric heating of a solid hydrate adequately. Practical value. Blocking plugs may occur due to hydrate formation when transporting gas through deep-water pipelines or through pipelines in cold environments. The elimination of such complications is a complex technical task. In particular, a special source of microwave radiation, which was proposed by the authors in previous works, can be used to unblock the pipeline. The device that makes the microwave radiation is located along the pipe axis. The results of this work allow us to evaluate the effectiveness of the microwave method for eliminating the gas hydrate plug. The mathematical model and computational method can be used in the development of appropriate technologies using a coaxial microwave heating source.

Methodology. The energy-efficient and smart control of indoor heating is based on the fact that a control system is to elaborate and provide a compromise solution as for comfortable perception of proper conditions of someones staying indoors and minimum consumption of energy resources. To do that, first of all the problem should be solved concerning recognition of different heating conditions by a smart control system aimed at providing a process of system learning and database formation. To complete this task, the parameters of one-dimensional dynamic models describing heat-exchange processes are proposed to be used as the information signs for the classification of situations in terms of heating relative to the uncontrolled electric heaters; the input value is the heater capacity, and the output value is the air temperature within the local indoor zone. Within the framework of the development of a method for classifying indoor heating conditions, dependences of the parameters of dynamic models of local indoor heating zones on the characteristics of local heating zones were analysed. Besides, certain regularities of a control process for heaters were determined; that helped provide accurate identification of the models of local heating zones without considerable changes in a preset temperature mode. Computational experiments made it possible to evaluate the accuracy of determination of information signs for the classification of heating conditions while representing real characteristics of indoor heat-exchange processes. Findings. The studies resulted in the development of a method for identifying dynamic properties of indoor heat zones for the cases of using uncontrolled electric heaters with two states. Originality. For the first time, certain regularities have been identified concerning a capacity control process for electric heaters with two states and a process of temperature measurement within the local indoor zones. The regularities made it possible to determine the parameters of dynamic models of indoor heat-exchange processes with high accuracy and without considerable changes in the preset temperature mode, and to use these parameters as information signs while classifying the heating conditions. Practical value. The obtained regularities of the processes of heater control and temperature measurement allowed developing a method for identification of dynamic properties of local indoor heat zones, which makes up the basis for a classification procedure of heating conditions.

A cultura do consumo e o endividamento excessivo: uma discussão sobre possíveis intervenções da educação financeira
Authors: Ancelmo Lúcia Aparecida , Freitas Carlos Cesar Garcia
Published: August 2022

A dificuldade em administrar recursos financeiros tem levado muitos brasileiros ao endividamento, pois nem todos possuem o conhecimento necessário para lidar com o dinheiro de maneira assertiva. Somado a esse fato, a cultura do consumo estimula o consumismo, com desejos intermináveis e no consumo acrítico, interferindo no equilíbrio financeiro, adquirindo bens que não estão dentro do orçamento, podendo levar ao endividamento. Já a Educação Financeira apresenta conceitos e objetivos de encontro a essa problemática, objetivando o equilíbrio da vida financeira, o consumo consciente e a poupança. Assim, por meio de pesquisa qualitativa realizou-se um levantamento bibliográfico considerando a questão norteadora: Como a Educação Financeira pode contribuir para minimizar os impactos do Consumismo e Endividamento na sociedade? Os aportes teóricos Bauman (2001; 2008), Baudrillard (1985), Bourdieu (1983) e ENEF (2012), possibilitaram uma discussão de possíveis articulações entre consumismo e endividamento e os objetivos da Educação Financeira nas Escolas, considerando suas contribuições para o consumo consciente e o equilíbrio financeiro. Inferiu-se que a Educação Financeira pode contribuir para a amenização dos problemas com o consumismo e o endividamento, utilizando conceitos e ferramentas que estimulem as habilidades e que viabilizem um processo reflexivo sobre as atitudes para o equilíbrio da vida financeira.

Sendo classificado como cisto de desenvolvimento, o cisto dentígero (CD) é uma patologia benigna que surge do acúmulo de fluido no espaço entre o folículo circundante à coroa de um dente não erupcionado. Sua origem é incerta e devido a sua classificação, lesões de desenvolvimento não se relacionam com reações inflamatórias como causa. Na maioria dos casos, o CD é relatado de forma assintomática, sendo por vezes descoberto em radiografias de rotina. Os aspectos radiográficos dessa patologia se revelam com uma área radiolúcida, unilocular e de limites bem definidos, circundada por um halo radiopaco esclerótico, sempre em associação à coroa de algum dente impactado. O tratamento a ser escolhido depende do tamanho da patologia, da idade do paciente, e de quais estruturas ou dentes estão envolvidos, além da colaboração do paciente. O tratamento mais comum é a enucleação total do cisto junto com a extração do elemento impactado. Este artigo tem como objetivo apresentar um relato de cisto dentígero em mandíbula de grande extensão, em região posterior do lado direito associado aos elementos dentários 48 e 47 em um paciente do sexo masculino, 29 anos, leucoderma, mostrando suas propriedades, clínicas, imaginológicas e histopatológicas e destacando sua forma de tratamento.

BMP´s are signaling proteins that belong to the Transforming Growth Factor-β (TGF-β) superfamily. These proteins promote the recruitment and differentiation of mesenchymal progenitor cells into bone forming cells, the osteoblasts and increase the rate of bone formation. The carrier systems to release rhBMP-2 to the action site are based on the use of free and soluble BMP incorporated into biopolymers such as collagen, gelatin, chitosan, hyaluronic acid and silk. The fused rhBMP-2-thioredoxin could be an interesting approach for new advances in the field of carrying systems of these growth factors. The fused protein thioredoxin can be useful as a coupling agent of BMP-2 to the carrier system, binding it to the surface of the matrix and it is one of the main aims of this work. The recombinant protein rhBMP-2 was produced by IPTG induction obtaining a soluble protein without the need for refolding process. The immobilization of rhBMP-2 at the surface of the TEMPO modified cellulose nanofibrils was indicated by FTIR spectroscopy. The cellular viability tests indicated increased proliferative behavior of both, C2C12 and stem cells from rats, when seeded in presence of rhBMP2 when compared to the free rhBMP2 substrate. The calcified extracellular matrix confirmed the increased activity of the rhBMP2-cellulose substrate, indicating the success of the proposed method. The cell proliferation assays indicated the method used to immobilize rhBMP2 onto the surface of the TEMPO modified cellulose was successful. The cells growth increased when compared to the reference sample free of rhBMP2.

The objective of this study was to evaluate some compositional and physicochemical changes that occur during UHT (Ultra-high temperature) milk storage for up to four months. A total of 120 samples of UHT milk were collected from two dairy plants in the state of Minas Gerais, Brazil, and stored under two temperatures (20°C and 30°C) during five periods (0, 30, 60, 90 and 120 days). The experimental design was completely randomized, in a 2x2x5 factorial arrangement, with six replicates per treatment (six batches). Evaluated parameters included fat, total protein, casein, lactose, total solids, solids nonfat (SNF) and milk urea nitrogen (MUN) contents, as well as acidity, density, freezing point and indexes of lipolysis and caseinomacropeptide (CMP). When compared to the Brazilian requirements for UHT milk, the mean values ​​for acidity, fat and SNF contents were in accordance with the standards ​​until the last day of storage. The other parameters are still not covered by the specific UHT milk legislation in Brazil. There was no change of relative density and lactose content also remained constant, except for a decrease at the fourth month. A significant increase, over storage time, in acidity, MUN, lipolysis and CMP indexes occurred. On the other hand, there was a significant decrease in SNF and protein contents. The results showed that there was a gradual loss of quality during UHT milk storage, aggravated by the rise in temperature. These findings demonstrate that UHT milk legislation could be improved by adding parameters such as lipolysis and CMP indexes.

Coffee growing is an important activity for the income of farms and the production of specialty coffees should be encouraged. However, it is necessary that this process respects the principles based on the economic, environmental, and social axes of sustainability. This research was carried out in the municipality of Conceição do Castelo, State of Espírito Santo, Brazil aiming to assess the initial benchmark of the sustainability of three farms. The results showed a gap in the three axes with intervention needs mainly related to economic standards, followed by social and environmental. Different interventions and adaptations need to be used on each farm aiming to reach better levels of adequacy according to sustainability criteria; however, the values of the families and their limitations must be respected, particularly the economic, social, and cultural conditions. The three coffee farms need adjustments for the production of specialty coffees, mainly related to economic criteria. In this way, farms will be able to reach new markets, add value to coffee beans, increase farm income and develop sustainability.

Este trabalho teve como objetivo principal identificar e analisar comparativamente a percepção de qualidade discente de uma universidade federal pública e de um centro universitário privado[1]. O instrumento utilizado captou sete dimensões da qualidade percebida em relação aos serviços educacionais ofertados: reputação mercadológica, segurança, atendimento administrativo, relacionamento interpessoal, infraestrutura, aspectos educacionais e aspectos acadêmicos. Obtiveram-se 160 respostas válidas. Caracterizaram-se as amostras, verificou-se a confiabilidade do estudo, realizaram-se os tratamentos descritivos por dimensão e identificaram-se as médias finais por entidade. As dimensões atendimento administrativo e infraestrutura obtiveram as maiores e menores médias respectivamente nas duas instituições. Registraram-se reclamações sobre cantinas e estacionamentos das entidades. Verificou-se que a IES privada alcançou médias numericamente superiores em todos os construtos do instrumento e na média final. No entanto, em tratamento estatístico por meio do teste de hipótese, concluiu-se que as diferenças entre as médias não apresentaram significância. Por fim, diagnosticou-se uma relevante contribuição teórica que poderá auxiliar na gestão dos serviços educacionais referente ao curso avaliado. Outra evidência ressaltada é a necessidade de ampliação de pesquisas científicas sobre a temática qualidade no ensino superior brasileiro.

Avaliar a tendência temporal de vínculos de trabalho para os profissionais enfermeiros da região sudeste durante o período de 2003 a 2018. Trata-se de um estudo ecológico de tendência temporal utilizando dados obtidos através de uma base de dados pública, analisou-se a tendência da geração de vínculos dos enfermeiros durante o período de 2003 a 2018, utilizando-se as equações polinomiais através dos recursos do software estatístico R.  Considerou-se tendência significativa quando o p-valor ≤ 0,05. A partir da construção da linha temporal, identificou-se a tendência estacionária na geração de vínculos para enfermeiros na região Sudeste com queda significativa de vínculos registrados no período. As tendências estacionárias observadas na região sudeste revelam uma possível estagnação dos postos de trabalho para enfermeiros. Este cenário pode influenciar na assistência de enfermagem segura e de qualidade uma vez que a redução da força de trabalho contratada pode gerar intensificação e sobrecarga dos que estão no mercado.

Objective: To compare the prevalence of radix in the mandibular first and second molars using cone beam computed tomography and panoramic radiography. Methods: 850 exams were analyzed, dated from January 2017 to February 2021, in a radiology clinic in the city of Brumado-Ba. Images were acquired using a Cranex 3D CT scanner. Thus, a total of 280 lower first and second molars were selected by tomographic images and then the images of the relative panoramic radiographs were separated. Radix prevalence was analyzed using On Demand software for the scans from CT and Scanora software for the panoramic radiographs. The data obtained were analyzed using descriptive and inferential statistics, using methods to compare between variables and methods of interest. A significance level of 5% was assumed for all analyzes. Results: No case of radix was identified in the analysis of panoramic radiograph images, corresponding to a percentage of 0%. In tomographic sections, this study showed that the prevalence of radix was 0.7%, 100% of which was radix entomolres. There was no statistically significant difference in the prevalence of these canals with respect to age group, sex, and group of teeth examined (first or lower second molars). Conclusion: It was concluded that CBCT is an important auxiliary method in the analysis of the presence of radix canals.

Kanker payudara adalah keganasan yang berasal dari epitel duktus maupun lobules di jaringan payudara. Di sisi lain, penyakit fibrokistik adalah benjolan teraba di payudara dan terkait dengan siklus menstruasi. Karena gejala awal yang mirip, pada pemeriksaan klinis, penyakit fibrokistik sering salah didiagnosis sebagai kanker payudara. Oleh karena tingginya kasus kanker payudara di Indonesia, penentuan stadium klinis dan pemeriksaan histopatologi diperlukan untuk menentukan diagnosis dan tata laksana lebih lanjut.Penelitian ini bertujuan untuk mengetahui bagaimana perbedaan kepadatan jaringan ikat dan perbedaan luas sel pada kanker payudara dan penyakit fibrokistik.Jenis penelitian ini adalah eksperimen dengan rancangan penelitian cross sectional. Sampel dalam penelitian ini adalah blok paraffin pasien kanker payudara dan penyakit fibrokistik di Rumah Sakit Islam Cempaka Putih Jakarta. Pengumpulan data ini dilakukan dengan data primer sediaan biopsi eksisi atau mastektomi pasien kanker payudara dan penyakit fibrokistik dan diolah menjadi sediaan slide menggunakan pewarnaan masson’s trichrome dan Hematoxylin Eosin. Analisis dilakukan menggunakan uji komparatif dua sampel yang tidak berpasangan dan distribusi tidak normal dengan uji Kolmogorov Smirnov.Penelitian ini menunjukkan bahwa rerata luas morfologi kelenjar pada kanker payudara lebih besar dibandingkan penyakit fibrokistik (226,324 um : 60,522 um). Berdasarkan hasil uji analisis didapatkan perbedaan yang bermakna secara statistik antara luas morfologi kelenjar pada kanker payudara dan penyakit fibrokistik. Semenetara jumlah jaringan ikat pada fibrokistik lebih banyak dibandingkan kanker invasif payudara. Kepadatan rata-rata jaringan ikat pada fibrokistik payudara sebesar 52%. Sedangkan kepadatan rata-rata jaringan ikat pada kanker payudara sebesar 29,17%. Berdasarkan hasil uji analisis Kolmogorov Smirnov didapatkan hasil yang signifikan secara statistik antara variabel kepadatan jaringan ikat pada kanker payudara dan penyakit fibrokistik (p kurang dari 0.05).Terdapat perbedaan bermakna jaringan ikat antara kanker payudara dengan penyakit fibrokistik. Sementara luas morfologi kelenjar pada kanker payudara lebih besar dibandingkan penyakit fibrokistik
