Effects the Surface of Solar-light Photocatalytic Activity of Ag-doped TiO2 Nanohybrid Material prepared with a Novel Approach
Authors: Nagaraj G. , Mohammed Mustafa K. A. , Abdulzahraa Haider G. , Tamilarasu S. 
Published: February 2021

Abstract
Surface modification with a nanomaterial has been confirmed to be an effective strategy to enhance the visible-light photodegradation efficiency of titanium dioxide nanoparticles (TiO2-NPs). In this regard, we used silver as an additive into TiO2-NPs to improve their photodegradation activity under visible light irradiation. Herein, a novel and eco-friendly process was developed to prepare the Ag-doped TiO2 nanohybrid and named as photon-induced method (PIM). The XRD technique showed that the prepared Ag-doped TiO2 has mixed phases of anatase and rutile. However, the rutile-only phase was detected for the pure TiO2-NPs at 700°C of calcination. Ultraviolet-visible (UV-vis) absorption spectra revealed a reduction in the bandgap energy of TiO2 after Ag doping. Besides, the addition of Ag resulted in a significant improvement of TiO2 morphology. Methlyene blue (MB) dye was chosen to be an organic target to investigate the photocatalyst activity of the TiO2-NPs. In this regard, the degradation rate of MB was found to be 100% for the Ag-doped TiO2, which is higher than that of pure rutile TiO2. The incorporation of Ag additive plays a significant role in the improvement of TiO2 stability and photodegradation performance due to the surface plasmon resonance phenomenon.

Published: February 2021

Abstract
Despite the various studies carried out to evaluate the effects of seismic sequences on structures, the matter of the time gap required to be considered between the mainshock and its corresponding aftershocks in dynamic analyses has never been focused on directly. This subtle but in the meantime effective subject, influences on the amount of accumulated damage caused by earthquake sequences. In the present study, 244 near fault ground motion components from 122 earthquakes were applied to a wide variety of single degree of freedom systems having vibrating period of 0.05 to 7 seconds with linear and nonlinear behavior. Furthermore, 2 planar steel moment-resisting frames, having 3 and 12 stories, were subjected to a set of 30 ground motion components. The purpose of this investigation was to estimate the required time for the structures to cease the free vibration at the end of the mainshock. The main purpose is to generate an estimation that is function of structural system’s parameters and the strong motion duration. Excellent correlations were obtained between the rest time and the following parameters: the combination of natural period of single degree of freedom systems, as well as the strong motion duration of earthquake sequences. In consequence, a formula is proposed which estimates the required optimized rest-time of a structure based on natural vibration period, as well as the duration of strong motion. Additionally, results obtained from the dynamic analysis of the steel frames validate the rest-time values achieved from the proposed formula.

Abstract
Increasing the development and diffusion of low-carbon technologies on a global scale is critical to mitigating climate change. Based on over two million patents from 1995 to 2017 from 106 countries in all major climate mitigation technologies, our analysis shows an annual average low-carbon patenting growth rate of 10 percent from 1995 to 2013. Yet, from 2013 to 2017 low-carbon patenting rates have fallen by around 6 percent annually, likely driven by declining fossil fuel prices and, possibly, a readjustment of investors’ expectations and a stagnation of public funding for green R&D after the financial crisis. The Paris Agreement does not appear to have reversed the negative trend in low-carbon patenting observed since 2013. Innovation is still highly concentrated, with Germany, Japan, and the US accounting for more than half of global inventions, and the top 10 countries for around 90%. This concentration has further intensified over the last decade. Except for China, emerging economies have not caught up and remain less specialised in low-carbon technologies than the world average. This underscores the need for more technology transfers to developing and emerging economies, where most of the future CO2-emissions increases are set to occur. Existing transfer mechanisms, such as the UN Technology Transfer Mechanism and the Clean Development Mechanism, appear insufficient given the slow progress of technology transfer.
Modeling of tumor radiotherapy with damage and repair processes
Authors: Zhao Jiantao , Wei Xin , Tian Jianjun Paul 
Published: February 2021

Abstract
Background: Under irradiation, some cells are damaged permanently and die while some damaged cells can be self-repaired and become normal cells. The same situation happens in tumor radiotherapy. There has been several models to calculate the probability of cell survival after irradiation, and mathematical models for tumor growth to incorporate cell survival probability in radiotherapy. However, there is no detailed study about how both radiation damage process and cell repair process impact outcomes of tumor radiotherapy. This study will focus on impacts of these two processes on tumor radiotherapy.
Methods: The study employs mathematical modeling. Based on established mathematical models for tumor growth and irradiation, a functional reaction diffusion system for tumor radiotherapy is proposed. The model has the tumor cell population and damaged tumor cell population, and tracks their movements in the tumor site. The model considers the repair time of damaged tumor cells as a delay parameter. Detailed analysis is conducted while numerical simulations are performed with glioma data.
Results: We obtain the radiation threshold which combines the tumor growth rate, the damaged cell death rate, and damaged cell repair rate. The radiation threshold is a decreasing function of radiation dose while the radiation damage rate is a increasing function of radiation dose. The radiation damage rate and repair time determine the outcome of radiotherapy. When the radiation damage rate is greater than the radiation threshold, radiotherapy may destroy the tumor while radiotherapy may control tumor growth and the tumor load decreases as the radiation dose increases when the radiation damage rate is less than the radiation threshold. For both situations, we also observe oscillations of two cell populations occurring from Hopf bifurcations and Turing instability appearing from a large repair time of damaged tumor cells and different cell motilities.
Conclusions: The damaged tumor cell repairing process increases the radiation threshold and complicates outcomes of radiotherapy. The medical implication of our results is that radiotherapy may control the tumor growth and the radiation dose can reduce the total tumor load when the damage rate is greater than the radiation threshold, and otherwise, radiotherapy may kill the tumor and the amount of the does not matter.

:
Compared to the classical chemicals, nanoparticles (NPs) exhibit unique properties,
which lead to challenges in sample preparation and analysis. Fractionation techniques
and, in particular, hollow fiber flow field flow fractionation (HF5) have recently
become popular in the characterization and quantification of nanomaterials, because of
their fine fractionation capability in the nanoscale-range. When dealing with NPs, a great
drawback during fractionation is the loss of particles in the fractionation devices, tubing
and connectors. There is a need for studies to systematically explore and assess the quality
of the fractionation process. A combination of two complementary mass-based setups
was used to determine particle loss in HF5. Inductively coupled plasma mass spectrometry
(ICP-MS) enabled the estimation of recovery rates for NPs after HF5 separation. Reciprocally,
laser ablation ICP-MS (LA-ICP-MS) permitted the evaluation of particles retained
on the hollow fiber. 15 nm Au-NPs in different concentrations were evaluated in
this study and showed a recovery level for Au-NPs of 50 – 65% based on the applied concentrations
after a complete HF5 separation run. Detection of sample deposition on the
hollow fiber by LA-ICP-MS indicated a sample loss of about 8%. These findings are important
for experiments relying on fractionation of low concentrated nanoparticulate samples.

BCR-ABL Transcript Level as Compared to LDH and Uric Acid Among Chronic Myeloid Leukemic Patients
Authors: Hailemariam Temesgen Sisay , Mehdi Mohammed , Kinde Samuel , Seifu Daniel , Edao Abebe 
Published: February 2021

Background:
Chronic myeloid leukemia is characterized by the presence of the Philadelphia
chromosome, which is caused by the breakpoint cluster region-Abelson fusion or joined gene.
A high concentration of BCR-ABL transcripts level can strongly forecast cytogenetic and hematologic
reversion in CML patients. However, the molecular test for BCR-ABL is costly and hardly
available in developing countries with low and middle-income. Owing to this, it is required to examine
other cost-effective and best diagnostic (prognostic) biomarkers.

Objective:
The present study aimed to estimate the total LDH and uric acid level as compared to
BCR-ABL transcript level among treated and treatment-naive Chronic Myeloid Leukemia (CML)
patients.

Methods:
A comparative cross-sectional study design was used to include eighty-one (81) CML patients
tested for BCR-ABL by GeneXpert RT-PCR transcript level at Tikur Anbessa Specialized
Hospital. The current study correlates LDH with BCR-ABL and hematological parameters using
the spearman correlation, Mann-Whitney U test, and roc curve data analysis tool.

Result:
A total of 81 CML patients were assayed; 46(56.8%) of them were in the medically treated
group, and the remaining 35 (43.2%) were treatment-naive patients. Significant positive correlations
were observed between LDH and BCR-ABL (r=0.79, P<0.001).The correlation coefficient
value of uric acid (r=0.295, p<0.008) with BCR-ABL showed a weak correlation between the two
test parameters. There was a statistically noteworthy (p<0.05) difference in the median level of
BCR-ABL and LDH among patients in the treatment group (median=21%, 350 U/L) and the treatment-
naive group (median=57%, 1246 U/L), respectively. For uric acid, there was no statistically
significant (p<0.542) difference between the study group. The AUC for LDH, Basophil, and WBC
was 0.881, 0.889, and 0.748, respectively, which showed better performance for the follow-up of
patients with CML than uric acid (0.695) and platelets (0.70).

Conclusion:
The CML LDH value strongly correlated with BCR-ABL transcript level, whereas
uric acid was weakly correlated with BCR-ABL. Hence, in parallel with the BRC-ABL transcript
level, these findings could be a patent for confirming the capability of LDH as an alternative cost--
effective diagnostic, prognostic biomarker, and a novel therapeutic target in CML disease.
Deformation Behavior, Fatigue and Fracture Surface Microstructure of Porous Titanium Nickelide
Authors: Marchenko Ekaterina , Yasenchuk Yuriy , Avdeeva Diana , Baigonakova Gulsharat , Gunther Sergey , Iuzhakova Mariya 
Published: February 2021

Background:
The porous SHS–TiNi alloy is a widely used material for repairing defects in
bone tissues.

Objective:
The objective of the study is to comprehensively investigate porous SHS–TiNi alloy samples
for fatigue strength under cyclic bending, to study deformation characteristics under quasistatic tension
and bending, and to carry out the fractographic analysis of fracture features.

Methods:
The study employed the electrospark method for cutting plates from a porous isotropic SHS–
TiNi rod 30 mm in diameter and 300 mm in length.

Results:
Deformation behaviour under tension and three-point bending of porous plates showed that
porous samples undergo viscoelastic deformation due to the austenite–martensite (A→M) phase transformation.
The fracture surfaces of elastic porous samples were studied by SEM. Microscopic studies of
fracture surfaces revealed zones of quasi-brittle fracture of martensite and viscous fracture of austenite.
The porous framework of intermetallic alloy exhibits a continuous brittle layer and numerous brittle
non-metallic inclusions. However, successful fatigue tests showed that brittle phases and inclusions do
not significantly affect deformation and fatigue characteristics of porous titanium nickelide. It was
found that 70% of porous samples sustain 106 cycles of deformation without fracture due to reversible
A→M→A phase transformations in the TiNi phase, which is one of the components of multiphase porous
alloy.

Conclusion:
Viscoelastic behavior of the porous sample and its high fatigue strength under cyclic loading
is due to reversible deformation of the TiNi phase. The corrosion-resistant layer of the porous
framework allows an effective use of SHS–TiNi.

Od ceremoniału papieskiego do ceremoniału biskupiego. Wpływ renesansowej Cappella Papale na liturgiczny rytm życia stolic biskupich
Authors: Krzych Bartłomiej Krzysztof 
Published: February 2021

Głównym źródłem i podstawą liturgii pontyfikalnych jest Pontyfikał (Pontificale Romanum) i Ceremoniał Biskupi (Caeremoniale Episcoporum). O ile pierwszy z nich jest pełnoprawną księgą liturgiczną, o tyle drugi jest księgą opisującą jedynie ceremonie (dla liturgii całego roku liturgicznego) oraz elementy etykiety obowiązującej na dawnych dworach biskupich, katedrach i kolegiatach, opisując niejako ich życie codzienne (od wyboru biskupa, przez obchody roku kościelnego, po szczegółowe funkcje ministrów). Ceremoniał Biskupi, wydany po raz pierwszy w 1600 roku (na polecenie ojców Soboru Trydenckiego), jest w istocie – jak podkreślają badacze i znawcy liturgii – ceremoniałem papieskim (Caeremoniale Romanum lub Caeremoniale Apostolicum) dostosowanym do realiów katedry biskupiej. Ceremoniał ten był dziełem tzw. wielkich mistrzów ceremonii papieskich (Agostino Piccolomini, Joannes Burchard, Paride Grassi). Okazuje się, że liturgia rzymska (zwłaszcza w jej formie pontyfikalnej, ale także w wymiarze parafialnym), przynajmniej w jej kształcie do początku drugiej połowy XX wieku, została skodyfikowana w ceremoniale papieskim, rozprzestrzeniając się na cały świat katolicki.

Published: February 2021

A gestação se tornou um período de fragilidade mediante a pandemia da COVID-19. Diante disso, este artigo apresenta um relato de experiência do projeto de extensão “Fale com a Parteira - PB” (FCP-PB), vinculado à Universidade Federal da Paraíba (UFPB), para teleorientações a mulheres do ciclo gravídico puerperal do Estado da Paraíba durante a atual pandemia. A gestação em si já é um fenômeno em que alterações anatômicas e fisiológicas predispõem a mulher ao acometimento de infecções respiratórias. No caso das brasileiras, o risco da contaminação pelo vírus SARS-Cov-2 aumenta em razão da situação de vulnerabilidade socioeconômica e de saúde que elas se encontram. Assim, visando diminuir a exposição à COVID-19, o projeto promove teleatendimento e educação em saúde obstétrica para todas as gestantes, puérperas e parturientes paraibanas, via Instagram e WhatsApp. Nos quatro meses de projeto, as mulheres que receberam atendimento gratuito e especializado por enfermeiras obstetras foram estimuladas a manter as recomendações da Organização Mundial da Saúde (OMS), no que tange ao isolamento social, para reduzir o risco de exposição ao SARS-Cov-2. Ademais, as mulheres que precisavam dos serviços de saúde foram orientadas sobre os centros de referência e medidas de segurança. O projeto “Fale com a Parteira-PB” também se apresentou com potencialidade para ser replicado por gestores da saúde tendo em vista que é de baixo custo e de acesso remoto rápido.

A Terapia Comunitária Integrativa (TCI) mostra-se como uma estratégia eficaz na prevenção e no enfrentamento dos desequilíbrios emocionais causados pela pandemia do novo coronavírus. Este artigo objetiva relatar a experiência das autoras na condução de um projeto de extensão acadêmica, desenvolvido com a Terapia Comunitária Integrativa, no qual se procurou clarificar as estratégias de enfrentamento utilizadas pelos participantes durante o período de distanciamento físico em virtude da pandemia pela Covid-19. Mesmo remotamente, percebe-se a TCI como espaço de acolhimento, de fala e de escuta dos seus participantes. Concluiu-se que, mesmo diante de um contexto difícil de saúde pública, os encontros virtuais de TCI possibilitaram a troca de estratégias de enfrentamento, a formação de redes de apoio e de autoestima, o que pode acarretar resultados positivos para a promoção da saúde mental da comunidade acadêmica e da população externa, participantes do projeto.
A INFLUÊNCIA DE DOCUMENTOS NORTEADORES NA PRÁTICA PEDAGÓGICA DE PROFESSORES DE EDUCAÇÃO FÍSICA DO ENSINO MÉDIO
Authors: Gonçalves Santos Gilmara , Cláudia Mara Niquini  
Published: February 2021

O presente artigo, fruto de uma dissertação de mestrado, teve como objetivo analisar a concepção de professores de Educação Física do Ensino Médio sobre os documentos norteadores para o ensino de Educação Física na escola, dentre eles os Parâmetros curriculares Nacionais (PCNS), Conteúdo Básico Comum-Minas Gerais (CBC-MG) e a Base Nacional Comum Curricular (BNCC), assim como, compreender em que medida esses documentos orientam o planejamento de suas aulas e das suas práticas pedagógicas. Trata-se de uma pesquisa de campo, com abordagem qualitativa, que investigou 6 professores de Educação Física das escolas públicas da cidade de Araçuaí-MG que atuam no ensino médio. Como instrumento de coleta de dados, optamos pela entrevista semiestruturada e análise do planejamento de ensino dos sujeitos pesquisados. Para o tratamento dos dados, recorremos à técnica de análise de conteúdo proposta por Bardin (1977). Os resultados evidenciam que a maioria dos professores utilizam o CBC-MG como referência para o planejamento das aulas e consideram a proposta importante para a prática pedagógica. Em relação aos PCNS e à BNCC, os professores relatam conhecê-los superficialmente. Entendemos que, devido à escassez de pesquisas que tratam sobre a sistematização dos conhecimentos da Educação Física na escola, os documentos norteadores se apresentam como um significativo suporte para o professor crítico planejar e organizar os conteúdos de suas aulas. No entanto, torna-se necessário haver um debate mais amplo nos processos de construção desses documentos, permitindo uma maior participação e reflexão dos docentes que se encontram no cotidiano e na realidade das escolas.
