Purpose: To determine the chemical constituents of the volatile oil of Chenopodium ambrosioides L. from Mianyang in Sichuan Province of China, and assess the sub-chronic toxicity of the volatile oil in mice.Methods: The volatile chemical components were analyzed by gas chromatography-mass spectrometry (GC-MS). Sixty Kunming mice were divided into six groups of ten mice each. One group served as control (no treatment), two groups were orally administered ρ-cymene at doses of 3 and 7 mg/kg, respectively, for 27 days, while three groups received the volatile oil at doses of 10, 25 and 40 mg/kg, respectively, for the same duration. Sub-chronic toxicity in the mice was evaluated by observing their general behavior, measuring serum levels of aspartate transaminase (AST) and alanine transaminase (ALT), evaluating liver, heart, kidney and thymus indices, and assessing the histological morphology of the organs.Results: The volatile oil contained 14 chemical components, of which α-terpinene and ρ-cymene accounted for 32.89 and 24.25 %, respectively. The volatile oil caused significant (p < 0.05) increase in liver index, and serum AST and ALT levels, and also induced distinct morphological changes in mouse liver, heart and kidney.Conclusion: The main volatile components of the oil are α-terpinene and ρ-cymene. The volatile oil showed dose-dependent toxicity in mice, thus lending some support for the safe use of C. ambrosioides in traditional medicine.

Published: January 2021

Purpose: To assess the efficacy and predictors of treatment response of chronic hepatitis C genotype 4 Egyptian patients with sofosbuvir and daclatasvir, with or without ribavirin.Methods: This prospective study enrolled 200 patients with chronic hepatitis C virus (HCV) genotype 4 infection who received sofosbuvir plus daclatasvir for 12 weeks, with the addition of ribavirin for treating cirrhotic patients. Immunological parameters such as natural killer (NK) cell percentage, phenotype, and serum C-X-C motif chemokine 10 (CXCL10) were evaluated prior to treatment and at the end of the treatment.Results: Overall, 92.5 % of the patients achieved sustained virological response at 12 weeks (SVR12), where the non-cirrhotic group had 96.29 % SVR12, while the cirrhotic group had 84.61 % SVR12. Nonresponders had lower pretreatment platelet count, higher CXCL10 levels, and lower baseline frequencies of NK cells and NK subgroup CD56- CD16+.Conclusion: Based on these results, the use of sofosbuvir plus daclatasvir with or without ribavirin for 12 weeks, is an effective regimen in the treatment of Egyptian patients infected with genotype 4 HCV. The predictors of non-response are advanced age, liver cirrhosis, lower pretreatment platelet count, higher level of CXCL10, lower baseline NK cells frequency and percentage of the dysfunctional subset CD56- CD16+.

Icariin induces autophagy and apoptosis of chondrocytes by inhibiting NF-κB signaling pathway
Authors: Xiong Jun , Zou Hui , Yu Yi
Published: January 2021

Purpose: To investigate the effect of icariin on autophagy and apoptosis of chondrocytes, and the associated mechanisms.Methods: The chondrocytes were randomly divided into control (PBS intervention), TNF-α intervention, icarin +TNF-α, and NF-κB inhibition +TNF-α, with 8 strains in each group. The levels of IL-1, IL-6 and IL-12 were assayed by ELISA. The mRNA and protein expressions of ATG5, ATG7, Bax and Bcl-2 cells were determined by polymerase chain reaction (PCR) and Western blotting, while protein expressions of p-p65 and IκBα were assayed using Western blotting.Results: In the cartilage tissue of rats in the icariin +TNF-α group and NF-κB inhibition +TNF-α group, IL-1, IL-6 and IL-12 levels were significantly lower than those in TNF-α treatment group (p < 0.05). The AATG5 mRNA and protein in cartilage tissues of rats in icariin +TNF-α and NF-κB inhibition +TNF-α groups were significantly higher than those in TNF-α group. Bax mRNA and protein in cartilage tissues of icariin +TNF-α and NF-κB inhibition +TNF-α groups were downregulated, relative to TNF-α group; on the other hand, Bcl-2 mRNA and protein were significantly higher than those of TNF-α group (p < 0.05). In the cartilage tissues of Icarin +TNF-α, NF-κB inhibition +TNF-α groups, P-p65 protein was significantly lower than that of TNF-α (p < 0.05).Conclusion: TNF-α enhances the production of a large number of inflammatory factors by cartilage cells, inhibits autophagy of cartilage cells, and promotes cell apoptosis through regulation of NF-κB signaling pathway.

Tourist assets of the cross-border railway line Brest–Włodawa–Chełm
Authors: Anisiewicz Renata
Published: January 2021

The article is to show tourist assets of the cross-border railway line Brest–Chełm, which is disrupted by a state border and the lack of a bridge on the Bug River barring access to Brest–Włodawa line section on the Belarus side and to Włodawa–Chełm section on the Polish side. The locally operating sections, built in the eighties of the twentieth century, of the strategic railway linking the Warsaw–Terespol line with the Vistula River Railroad (Nadwiślańska) have a great potential for the development of railway tourism. The line runs along prized nature areas of the macro-regions West Polesie and Wołyńskie Polesie. Sundry landscapes of the border countryside and their biological diversity are decisive in enjoying the highly valued scenery along the line on the Polish side. The attractiveness of the Belarus side – in practice accessible to foreigners following the introduction of the tourist and recreation zone ‘Brest’ in 2018 – is usually associated with the uncommon rules of travelling by train in the Belarus cross-border region. Both fragments of the line Brest–Chełm lead to and run through interesting tourist localities and cross-border culture sites. The article also touches on the present restrictions for railway tourism along this route, and the chances of reviving regular traffic in the Polish section in view of the governmental programme Kolej+.
Resistance in adapting to sustainable mobility and new Sustainable Mobility Indicator – case study of a Polish agglomeration
Authors: Matusiewicz Maria
Published: January 2021

Sustainable growth is now the foundation of economic growth, especially if the 2020 pandemic prompts the conclusion that the over-exploitation of planet’s goods is ultimately turning against humanity. Despite the climate crisis, Poles are reluctant to give up cars, and city authorities in Poland do not increase the quality and efficiency of public transport. Young people around the world are seen as hope for changing trends. The aim of the article is to verify the hypothesis about greater awareness of young people in Poland about climate change, manifested by mobility habits, compared to the older generation. The hypothesis was verified by a study onducted on a group of 67 students commuting to the university at the age of 21-23 and a group of 45 commuters aged 25-65. The Sustainable Mobility Indicator (SMI) was created for the purposes of the article. The SMI considers daily travels of residents of a large Polish city. With the use of the created indicator, the hypothesis was rejected.

Authors: VAN SY NGUYEN , THANH TAM NGUYEN
Published: January 2021

This paper presents finite element simulation of the crash behavior and the energy absorption characteristics of S-shape square tubes which were fully or partially filled with aluminum foams. Base on the numerical results, it is found that, the density, the length of the filled foam and the thickness of tube directly affect the specific energy absorption (SEA) and peak crushing force (PCF) of the S-shape tubes. In this paper, the multi-objective particle swarm optimization (MOPSO) algorithm is employed to seek for optimal designs for the partial foam-filled S-shape tubes (PFSTs) and the full foam-filled S-shape tubes (FFSTs) with various design parameters such as the density, the length of filled foam and the thickness of tube, where response surface models are established to formulation SEA and PCF. The optimization results showed the energy absorption capability per unit mass of the PFSTs is more powerful than that of the FFSTs while the PCF constrained under the same level.

Authors: DANG KHOA TRAN NGOC
Published: January 2021

This paper reports a new compliant bistable micromechanism (BM) with the flexibility of force output under a space constraint. The mechanism has four Bézier curved beams and a shuttle mass at its center. Bézier curves offer high flexibility for design of beam shapes of BMs. Compared to the conventional BMs with cosine curved beams and slanted straight beams, the BM with Bézier curved beam can be designed to have smaller switching forces under the same device area and thickness.
Named Entity Recognition in Low-resource Languages using Cross-lingual distributional word representation
Authors: Melatagia Yonta Paulin , Mbouopda Michael Franklin
Published: January 2021

Named Entity Recognition (NER) is a fundamental task in many NLP applications that seek to identify and classify expressions such as people, location, and organization names. Many NER systems have been developed, but the annotated data needed for good performances are not available for low-resource languages, such as Cameroonian languages. In this paper we exploit the low frequency of named entities in text to define a new suitable cross-lingual distributional representation for named entity recognition. We build the first Ewondo (a Bantu low-resource language of Cameroon) named entities recognizer by projecting named entity tags from English using our word representation. In terms of Recall, Precision and F-score, the obtained results show the effectiveness of the proposed distributional representation of words

La reconnaissance des entités nommées (REN) est une tâche fondamentale du TALN dont le but est d'identifier les expressions telles que les noms de personnes, de lieux et d'organisations dans un texte. Il existe de nos jours plusieurs systèmes de REN, cependant les données nécessaires pour les utiliser dans le traitement des langues peu dotées telles que les langues camerounaises ne sont pas disponibles. Nous exploitons le fait que les entités nommées apparaissent rarement dans les textes pour définir une nouvelle représentation distributionnelle interlingue des mots, qui soit adaptée à la REN. En utilisant notre représentation, nous projectons les entités nommées de l'anglais vers l'ewondo (une langue bantou du Cameroun); nous obtenons donc le tout premier modèle de reconnaissance des entités nommées en langue ewondo. Les résultats en terme de précision, rappel et f-mesure montrent l'efficacité de notre représentation

Comparing classic time series models and the LSTM recurrent neural network: An application to S&P 500 stocks
Authors: Oliver Muncharaz J.
Published: January 2021

In the financial literature, there is great interest in the prediction of stock prices. Stock prediction is necessary for the creation of different investment strategies, both speculative and hedging ones. The application of neural networks has involved a change in the creation of predictive models. In this paper, we analyze the capacity of recurrent neural networks, in particular the long short-term recurrent neural network (LSTM) as opposed to classic time series models such as the Exponential Smooth Time Series (ETS) and the Arima model (ARIMA). These models have been estimated for 284 stocks from the S&P 500 stock market index, comparing the MAE obtained from their predictions. The results obtained confirm a significant reduction in prediction errors when LSTM is applied. These results are consistent with other similar studies applied to stocks included in other stock market indices, as well as other financial assets such as exchange rates.
Processes of Coping with Difference among Adolescents
Authors: Powroznik Natalie , Tepeli Dilek A. , Loth Martina
Published: January 2021

Against the backdrop of their collective identity, identity formation poses a special challenge to young Alevis and Afghan Christians. In Turkey, Alevis constitute a marginalized group not officially recognized by the state. In Afghanistan, conversion to Christendom is denounced as apostasy and is punished with death. This contribution compares the coping strategies of two young adults who are radically segregated by the state’s majority due to their marginalized religious identity. German diaspora offers new degrees of freedom. Thus, besides many psychosocial burdens for immigrants and their descendants, the two adolescents can confidently accept their difference and integrate it into their diverse identity.

Vacinas contra a Covid-19: estado da arte
Authors: Macedo Souto Xênia
Published: January 2021

O SARS-CoV-2, agente etiológico da COVID-19, já infectou quase 14 milhões de pessoas e resultou em, aproximadamente, 592 mil mortes. A publicação da sequência genética do SARS-CoV-2, em 11 de janeiro de 2020, desencadeou intensa corrida global para desenvolver uma vacina efetiva contra o vírus. Neste contexto, essa revisão tem como objetivo apresentar o panorama atual da busca mundial por vacinas contra a COVID-19. Tentativas passadas de produzir uma vacina para as doenças dos coronavírus SARS e MERS geraram um conhecimento substancial sobre a função e estrutura desse grupo viral, o que favoreceu o desenvolvimento de plataformas de produção de vacinas para a COVID-19. No entanto, os desafios para a obtenção de um produto desse tipo que seja seguro, eficaz e acessível, em um curto espaço de tempo, são grandes. Apesar disso, até o momento,163 candidatos à vacina para a COVID-19 estão sendo desenvolvidos e o potencial de vacinas inespecíficas avaliado. Embora a doença já tenha sido controlada em alguns países, a pandemia está longe de terminar segundo a Organização Mundial da Saúde. Esse cenário torna a busca por intervenções profiláticas desse tipo ainda imperativa a fim de reduzir a morbimortalidade se o vírus se estabelecer na população.

Published: January 2021

A água é uma substância primordial para manutenção dos seres vivos, sendo utilizada em  diversos fins, como consumo humano, lazer, irrigação, entre outros. A qualidade da água está diretamente ligada ao modo de uso e ocupação do solo, ao clima, topografia, geologia, cobertura vegetal e constituintes de uma bacia hidrográfica, ou seja a qualidade da água está relacionada tanto com os aspectos naturais quanto antrópicos. Devido à importância desse recurso natural, esse trabalho teve como objetivo realizar análises de alcalinidade, cloretos, dureza, temperatura e condutividade em amostras de água do município de Almenara – Minas Gerais, afim de conciliar os conhecimentos teóricos, sobre coleta de amostras e o método de volumetria ácido-base, de precipitação e de complexação, com os conhecimentos práticos de uma análise de qualidade da água. Essas análises fizeram parte de uma aula prática da disciplina de Química Analítica do curso de Engenharia Agronômica do Instituto Federal do Norte de Minas Gerais, campus Almenara. Foram coletadas três amostras de água, uma do rio Jequitinhonha, uma de nascente e outra em uma residência da cidade. Os resultados das análises demonstram que as três amostras apresentaram seus parâmetros de acordo com os determinados pela Resolução CONAMA 357 de 2005 do Conselho Nacional de Meio Ambiente e pela Portaria de Consolidação 5 de 2017 do Ministério da Saúde.

Revolução Cubana, literatura e homossexualidade: disputas pela memória de Virgilio Piñera em Mariel – Revista de Literatura y Arte (1983-1985)
Authors: Ferreira Drummond Caroline Maria
Published: January 2021

Mariel – Revista de Literatura y Arte foi fundada em 1983, em Miami, por escritores cubanos exilados nos Estados Unidos durante o exílio massivo de Mariel (1980), e circulou até 1985 nos Estados Unidos, América Latina e Europa. O projeto editorial coletivo era oposicionista ao regime revolucionário cubano e declarava-se anticomunista, antitotalitário, defensor da democracia e das liberdades individuais, possuindo pujante caráter de denúncia. Em nosso estudo, analisamos como os intelectuais que colaboraram com a revista debateram a literatura, a homossexualidade e a identidade nacional. Nossa proposta central é compreender como o projeto editorial constituiu uma oposição política ao governo revolucionário cubano durante o exílio nos Estados Unidos, por meio de disputas pelas memórias da Revolução e da intelectualidade cubana. Dessa forma, investigamos a seção Confluencias da revista, que estabelecia um “contra-cânone” combativo da literatura cubana, com foco no escritor Virgilio Piñera.

A TRIBUTAÇÃO DO INDÉBITO TRIBUTÁRIO DECORRENTE DE DECISÃO JUDICIAL TRANSITADA EM JULGADO PELO IRPJ E PELA CSLL
Authors: Tonelli Júnior Renato Adolfo
Published: January 2021

O trabalho discute o momento em que deve ocorrer a tributação pelo IRPJ e pela CSLL do indébito tributário reconhecido por decisão judicial transitada em julgado. A análise adota como premissas teóricas considerações gerais sobre a tributação da renda, especialmente a constatação de que renda disponível é renda líquida, assim como o princípio da realização da renda, da perspectiva do evento crítico, que corresponde ao momento em que se verifica a sua disponibilidade. Em seguida, o tema é examinado nas duas modalidades de aproveitamento do crédito pelo contribuinte: no recebimento de valores em espécie através de precatório ou de requisição de pequeno valor ou na compensação administrativa, na sistemática de tributação tanto pelo regime de caixa, como pelo regime de competência.
RECEITA TRIBUTÁVEL E REDUÇÃO DE DÍVIDAS NA RECUPERAÇÃO JUDICIAL
Authors: Marques Thiago de Mattos
Published: January 2021

Este estudo visa demonstrar os impactos fiscais decorrentes do conceito de receita tributável sobre as empresas envolvidas em um cenário de recuperação judicial: tanto empresas devedoras (em recuperação), como empresas credoras. A partir da análise de dois requisitos necessários para a configuração de receita tributável, que apontam para a exigência de ingresso financeiro que revele efetiva capacidade contributiva para que fique caracterizada a receita tributável, o estudo demonstrará não apenas que a redução de dívidas não pode ser considerada como receita tributável da perspectiva das empresas devedoras, mas também que o perdão de dívidas (ainda que parcial) autoriza as empresas credoras a recuperar tributos eventualmente recolhidos sobre valores que, na realidade, não foram recebidos.
A REGRA-MATRIZ DE MODULAÇÃO DOS EFEITOS (RMME) NA DECISÃO DE INCONSTITUCIONALIDADE EM MATÉRIA TRIBUTÁRIA
Authors: Salum Vinicius Dourado Loula
Published: January 2021

O artigo pretende construir uma regra-matriz de modulação dos efeitos (RMME) nas decisões de inconstitucionalidade em matéria tributária. O trabalho transita pelo estudo tanto dos modelos de controle de constitucionalidade quanto do postulado da proporcionalidade, para, enfim, compreender as raízes do instituto da modulação dos efeitos, aplicando esta técnica na hipótese de decisão de inconstitucionalidade de norma jurídica de tributação e no caso da inconstitucionalidade de norma jurídica de desoneração tributária. Trata-se de uma norma de estrutura, que traz no antecedente (hipótese) a descrição de um fato cuja ocorrência somente se verifica após a aplicação do postulado da proporcionalidade em suas três dimensões (adequação, necessidade e proporcionalidade stricto sensu), e no consequente prescreve a modificação do comando normativo que declara a inconstitucionalidade da lei ou ato normativo do Poder Público.
IMUNIDADE RECÍPROCA EM SOCIEDADES ESTATAIS
Authors: Zilveti Fernando Aurelio
Published: January 2021

O Estado e as sociedades estatais sofreram alterações em função da evolução socioeconômica. A maior participação estatal na atividade econômica é um reflexo disso, bem como do esgotamento de alguns modelos econômicos típicos do século XX. Naturalmente, o conceito de imunidade recíproca aplicado às empresas estatais sofre ao longo do tempo ajustes axiológicos segundo à perspectiva constitucional do intérprete do direito. Este artigo procura explorar o tema da imunidade recíproca a partir da constituição do Estado Federal e verificar como a corte constitucional STF garante esse direito às empresas estatais.
OS PRINCÍPIOS CONSTITUCIONAIS DA UNIVERSALIDADE E DA PROGRESSIVIDADE COMPORTAM UM REGIME DIFERENCIADO NA TRIBUTAÇÃO DO GANHO DE CAPITAL?
Authors: Freire André Borges Coelho de Miranda
Published: January 2021

À luz da previsão constitucional de que o imposto sobre a renda e sobre os proventos de qualquer natureza atenderá aos critérios da universalidade e da progressividade, o presente artigo propõe-se a analisar se o tratamento tributário conferido aos ganhos de capital comporta, sob essa previsão, um regime diferenciado. Partindo-se da teoria da concretização normativa de Friedrich Müller, estudam-se as peculiaridades dos ganhos de capital e como elas foram tratadas pela legislação ao longo do tempo, para concluir, depois de analisado o conteúdo dos princípios constitucionais reitores do imposto de renda, que dar-lhes tratamento especial não só é possível, como exigível.
SEGURANÇA JURÍDICA E MUDANÇA JURISPRUDENCIAL: O CASO DA PROGRESSIVIDADE DOS IMPOSTOS REAIS NO ENTENDIMENTO DO STF
Authors: Gomes André Silva
Published: January 2021

Este estudo se propõe a analisar o fenômeno da mudança de jurisprudência e seus efeitos sobre a segurança jurídica, focando especificamente no caso do entendimento do Supremo Tribunal Federal sobre a aplicação da progressividade de alíquotas aos impostos reais. Inicialmente apresenta-se o conteúdo normativo da segurança jurídica como princípio garantidor de um estado de coisas em que haja estabilidade normativa e confiança na manutenção dos posicionamentos dos tribunais, o que se faz por meio da consolidação e observação das orientações jurisprudenciais. Em seguida, examina-se o fenômeno da mudança de jurisprudência, que se dá quando um tribunal revê posicionamento anteriormente adotado sem que tenha ocorrido qualquer novidade fática ou normativa que influencie a nova decisão, baseando-se apenas nos mesmos elementos já existentes quando da tomada da primeira decisão. A mudança jurisprudencial, quando implementada, deve ser devidamente justificada, e devem ser tomadas medidas de mitigação dos seus efeitos. Ao final, analisa-se o histórico do posicionamento adotado pelo STF com relação à aplicação da progressividade de alíquotas aos chamados impostos reais, concluindo-se que, a despeito de possuir um histórico jurisprudencial consolidado e estável no sentido da inaplicabilidade da progressividade a esses impostos, no julgamento do RE 562.045 a Corte efetivamente realizou uma mudança de jurisprudência sem que tenham sido observados os requisitos de devida justificação. Com isso, foi causado um prejuízo à estabilidade e confiança inerentes à segurança jurídica.

Published: January 2021

ABSTRAK       Kecurigaan umat manusia terhadap bidang studi teologi Kristen pada abad XXI adalah tantangan baru bagi kekristenan masa kini. Orang menganggap bahwa teologi adalah sebuah bidang studi yang kuno dan telah hilang ketenarannya di dunia akademis. Memperhatikan hal di atas, maka dibuatlah penelitian untuk mengkaji ulang secara historis dan teologis tentang urgensitas bidang studi teologi di abad XXI. Untuk menemukan jawabannya, maka dibuatlah sebuah penelitian dengan pendekatan kualitatif dan menggunakan metode penelitian kepustakaan (library research).  Hasilnya adalah teologi adalah jawaban atas segala ”kegalauan” manusia tentang problematika kehidupan, teologi menuntun manusia memahami Allah Pencipta, teologi menjadi pedoman hidup manusia, teologi menuntun manusia memiliki kehidupan kekal dibalik kematian. Maka teologi adalah guru bagi ilmu pengetahuan (science), sehingga teologi wajib memberikan evaluasi terhadap ilmu pengetahuan (science) dengan cara intergrasi.   

 

ABSTRACT

       Humanity's suspicion of the field of Christian theology in the XXI century is a new challenge for Christianity today. People think that theology is an ancient field of study and has lost its fame in the academic world. Noting the above, a study was made to review historically and theologically about the urgency of theological studies in the XXI century. To find the answer, a study was made using a qualitative approach and using the method of library research. The result is that theology is the answer to all the "turmoil" of humans about the problems of life, theology leads people to understand the Creator God, theology is the guide to human life, theology leads humans to have eternal life behind death. So theology is a teacher for science (science), so theology must provide an evaluation of science (science) by way of integration.
Successful treatment of refractory Gastric Antral Vascular Ectasia (GAVE) in a cirrhotic patient with transcatheter arterial embolisation in a tertiary care facility in Pakistan: a case report
Authors: Alam Laima , Ayesha Usmani  , Admin
Published: January 2021

Abstract
Gastric antral vascular ectasia (GAVE) is a rare but important cause of upper gastrointestinal bleeding that may present with refractory anaemia or overt gastrointestinal bleeding requiring multiple admissions and resuscitation. Although endoscopic therapies are considered first line treatment for the management of refractory gastric antral vascular ectasia, angiographic embolisation of the culprit vessel(s) may emerge as an effective and safe treatment modality in the near future. Here, we present the case of a middle-aged gentleman with refractory gastric antral vascular ectasia, who was not responding to repeated sessions of Argon Plasma Coagulation (APC) and was successfully treated with trans-catheter arterial embolisation of gastro-duodenal artery.

According to WHO, 420 million adults worldwide are suffering from diabetes. The diabetic patient should regularly verify and control their blood glucose levels. However, the existing blood glucose meters use a needle to collect blood, thus causing problems such as pain and infections. A non-invasive blood glucose meter is a measuring instrument that can avoid these problems, but such an instrument has not been developed to date. Diabetic patients should ensure blood glucose control and exercise therapy: however, the difficulty of management and lack of guidance on exercise therapy are problematic issues that need to be overcome. In this study, a non-invasive blood glucose meter and blood glucose control system has been developed, which can be used along with a healthcare sensor equipped with a non-invasive blood glucose measurement function.

Construction of structures on soft soil is a challenging task and considered as one of the biggest concerns in geotechnical engineering. Binders that are environmentally friendly such as fly ash based geopolymer have been explored widely. In this study, the agro-waste material, Palm Oil Fuel Ash (POFA) was used to produce an environmentally friendly geopolymer binder to be used in soft soil stabilization. POFA was used in three ratios; 10%, 20% and 30% of dry weight of soil to produce geopolymer. Sodium hydroxide (NaOH) was used as an alkali activator at 12 molarity along with sodium silicate (Na2SiO3). Physical properties of soil (Atterberg Limits, Plasticity Index, and Linear Shrinkage Limit) and compaction assessment; before and after mixing with the geopolymer binder were investigated. The studied soil was classified as an inorganic high plasticity silt (MH), according to the Unified Soil Classification System (USCS). From compaction results; optimum moisture content (OMC) values showed a decreased pattern from 24.7% to 17.5%; and maximum dry density (MDD) increased from 1.37 Mg/m3 to 1.73 Mg/m3 for geopolymer with POFA ranging from 0% to 30% of the dry weight of soil, respectively. The optimum dosage of POFA based geopolymer was found to be 30% according to all tests mentioned. These properties suggest the potential use of the agro-waste based geopolymer binder to stabilize the soft soil.

The object detection system is a computer technology related to image processing and computer vision that detects instances of semantic objects of a certain class in digital images and videos. The system consists of two main processes, which are classification and detection. Once an object instance has been classified and detected, it is possible to obtain further information, including recognizes the specific instance, track the object over an image sequence and extract further information about the object and the scene. This paper presented an analysis performance of deep learning object detector by combining a deep learning Convolutional Neural Network (CNN) for object classification and applies classic object detection algorithms to devise our own deep learning object detector. MiniVGGNet is an architecture network used to train an object classification, and the data used for this purpose was collected from specific indoor environment building. For object detection, sliding windows and image pyramids were used to localize and detect objects at different locations, and non-maxima suppression (NMS) was used to obtain the final bounding box to localize the object location. Based on the experiment result, the percentage of classification accuracy of the network is 80% to 90% and the time for the system to detect the object is less than 15sec/frame. Experimental results show that there are reasonable and efficient to combine classic object detection method with a deep learning classification approach. The performance of this method can work in some specific use cases and effectively solving the problem of the inaccurate classification and detection of typical features.

Natural rubber (NR) glove disposal is not environmentally appropriate and a range of approaches have been suggested to overcome the problem. Herein we indicate a simple method for producing high-value nanotubes from waste NR glove as a partial solution to the environmental problem. The laboratory-based waste NR glove was selected as a carbon precursor. Carbon nanotubes (CNTs) were synthesized using chemical vapor deposition (CVD) method comprising ferrocene over SiO2 substrate, which acted as a catalyst and surface for the carbon conversion process. The growth temperature was varied using 500, 600 and 700°C. The carbon precursor was analyzed using thermogravimetric analysis (TGA) to determine the optimum thermal decomposition of the waste. The CNTs collected after CVD process were analyzed using Raman spectroscopy, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM). Optimization studies to determine the effect of temperature showed that the highest yield of CNTs was produced under a reaction temperature of 700°C (yield % = 5.47%, Raman ID/IG ratio = 0.82). The nanomaterials formed confirmed as CNTs and amorphous carbon under TEM images of the tubular structure of the products with a diameter range of 13 – 16 nm.
