Authors: Joshi Ila , Abdul Nazeer Rasool
Published: June 2021

Background:

Oratosquilla woodmasoni is one of the marine squilla species, which is
found in the entire Asia-Pacific region. This current study assesses the species as the main basis of
both ACEi and antioxidant peptide.

Objective:

To isolate the ACEi peptide derived from O. woodmasoni and examine its ACE inhibition
along with antioxidant potential.

Materials and Methods:

The squilla muscle protein was hydrolysed using alcalase and trypsin enzymes
for 12 hours and tested for DH. The hydrolysates were examined for their ACEi activity and
then the best hydrolysate was sequentially purified in various chromatographical methods. The purified
peptide was studied for anti-oxidant and functional properties, followed by amino acid sequencing.
The purified peptide was also evaluated for its toxicity by in vitro cell viability assay.

Results:

The DH% was found to be 47.13 ± 0.72% and 89.43 ± 2.06% for alcalase and trypsin, respectively.
The alcalase 5th-hour hydrolysate was detected with potent activity (65.97 ± 0.56%) using
ACEi assay and was primarily fractionated using ultrafiltration; the maximum inhibitory activity
was found with 77.04 ± 0.52% in 3-10 kDa fraction. Subsequently, the fraction was purified using
IEC and GFC, in which the AC1-A2 fraction had higher antihypertensive activity (70.85 ±
0.78%). The non-toxic fraction showed hexapeptide HVGGCG with molecular weight 529 Da with
great potential of antioxidant activity along with functional property.

Conclusion:

This peptide could be developed as a potential ACE-inhibitory and antioxidant agent.
Benzotriazacycle Cored Perylene Diimide Non-fullerene Acceptors for
High-performance Organic Solar Cells
Authors: Deng Min , Ji Zhenkai , Xu Xiaopeng , Yu Liyang , Peng Qiang
Published: June 2021

Background:

Perylene diimide (PDI) is among the most investigated non-fullerene electron
acceptor for organic solar cells (OSCs). Constructing PDI derivatives into three-dimensional propellerlike
molecular structures is not only one of the viable routes to suppress the over aggregation tendency
of the PDI chromophores but also rise possibilities to tune and optimize the optoelectronic property of
the molecules.

Objective:

In this work, we reported the design, synthesis, and characterization of three electronaccepting
materials, namely BOZ-PDI, BTZ-PDI, and BIZ-PDI, each with three PDI arms linked to
benzotrioxazole, benzotrithiazole, and benzotriimidazole based center cores, respectively.

Method:

The introduction of electron-withdrawing center cores with heteroatoms does not significantly
complicate the synthesis of the acceptor molecules, but drastically influences the energy levels
of the propeller-like PDI derivatives.

Result:

The highest power conversion efficiency was obtained with benzoxazole-based BOZ-PDI
reaching 7.70% for its higher photon absorption and charge-transport ability.

Conclusion:

This work explores the utilization of electron-withdrawing cores with heteroatoms in the
propeller-like PDI derivatives, which provides a handy tool to construct high-performance nonfullerene
acceptor materials.
Identification and Description of Balance, Mobility, and Gait Assessments Conducted via Telerehabilitation for Individuals With Neurological Conditions: Protocol for a Scoping Review (Preprint)
Authors: O'Neil Jennifer , Barnes Keely , Morgan Donnelly Erin , Sheehy Lisa , Sveistrup Heidi
Published: June 2021

BACKGROUND

The COVID-19 global pandemic pushed many rehabilitation practitioners to pivot their in-person practice to adopt telerehabilitation as their main method of delivery. In addition to documenting information on interventions used with clients, it is best practice for therapists to use reliable and validated outcome measures to inform their interventions.

OBJECTIVE

Through this scoping review, we aim to identify (1) which outcomes are being used remotely to assess balance, mobility, and gait in patients with neurological conditions, and (2) what psychometric data (validity, reliability, etc.) for remotely administered outcomes are available.

METHODS

Three main concepts will be included in our search: (1) neurological conditions; (2) administration by telerehabilitation; and (3) outcome measures for balance, mobility, and gait. Studies reporting remote assessment of neurological conditions published since 1990 will be included. The database search will be completed in MEDLINE (Ovid), CINAHL, PubMed, PsycINFO, EMBASE, and Cochrane. Gray literature including dissertations, conference papers, and protocol papers will also be sourced. Two reviewers will independently screen each title and abstract using pre-established inclusion and exclusion criteria. Manuscripts that appear to meet the criteria will be subject to further review, and full-text extraction using a pre-piloted extraction sheet if all criteria are met. The data will be categorized by assessment types describing impairments (such as balance, strength, and mobility) or activity limitations or participation restriction (such as functional mobility, ambulatory functions, and activities of daily living).

RESULTS

This scoping review will document outcome measures currently used in the remote assessment of neurological conditions. To date, 235 titles and abstracts were screened. We are in the process of finalizing the full text screening for the inclusion of articles. We expect the full screening to be completed in November 2021 and data analysis in January 2022. Our results are expected to be published in early 2022.

CONCLUSIONS

The optimal use of telerehabilitation as a mode to deliver rehabilitation intervention should be coupled with the completion of validated outcome measures. Therefore, it is crucial to further our knowledge on remote outcome measures and therapeutic assessments.

The use of chatbots as supportive agents for people seeking help for drug and alcohol addiction: A systematic review. (Preprint)
Authors: Ogilvie Lisa , Carson Jerome , Prescott Julie
Published: June 2021

BACKGROUND

The use of chatbots in healthcare is an area of study receiving increased academic interest. As the knowledge base grows, the granularity in the level of research is being refined, seeing more targeted work in specific areas of healthcare, for example, chatbots for anxiety and depression, cancer care, and pregnancy support. This paper focuses on the targeted application of chatbots in drug and alcohol addiction.

OBJECTIVE

The aim of this paper is to systematically review and summarise the research conducted on the use of chatbots in the field of addiction, specifically the use of chatbots as supportive agents for those who suffer from drug and alcohol addiction.

METHODS

A systematic search of bibliographic databases using the broad search criteria of “chatbot and addiction,” identified papers for screening. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Mixed Methods Appraisal Tool were used, which resulted in the quality assessment and review of 5 papers.

RESULTS

Although the body of research in this field is limited, what has been published shows promising results. A combination of quantitative, qualitative, and mixed methods studies were reviewed, among which statistically significant findings were reported on the efficacy of chatbots targeted at drug and alcohol addiction. These findings were also substantiated in the qualitative work reviewed. A strong message of caution was conveyed however on the ethical implications of using chatbots to afford support to addicted individuals.

CONCLUSIONS

The literature reviewed shows that more work is needed to appreciate solutions that leverage existing data, such as big data available from social media, or that which is accessed by prevalent market leading chatbots. It also highlighted ethical concerns over the use of a non-human agent to afford support to those with drug and alcohol addiction. It was reported however, that statistically significant results were returned for ‘bespoke’ chatbots in this area of healthcare, setting a promising foundation for future work.
Re-examining COVID-19 Self-Reported Symptom Tracking Programs in the United States: Updated Framework Synthesis (Preprint)
Authors: Janvrin Miranda Lynn , Korona-Bailey Jessica , Koehlmoos Tracey Pérez
Published: June 2021

BACKGROUND

Early in the pandemic, in 2020, Koehlmoos et al completed a framework synthesis of currently available self-reported symptom tracking programs for COVID-19. This framework described relevant programs, partners and affiliates, funding, responses, platform, and intended audience, among other considerations.

OBJECTIVE

This study seeks to update the existing framework with the aim of identifying developments in the landscape and highlighting how programs have adapted to changes in pandemic response.

METHODS

Our team developed a framework to collate information on current COVID-19 self-reported symptom tracking programs using the “best-fit” framework synthesis approach. All programs from the previous study were included to document changes. New programs were discovered using a Google search for target keywords. The time frame for the search for programs ranged from March 1, 2021, to May 6, 2021.

RESULTS

We screened 33 programs, of which 8 were included in our final framework synthesis. We identified multiple common data elements, including demographic information such as race, age, gender, and affiliation (all were associated with universities, medical schools, or schools of public health). Dissimilarities included questions regarding vaccination status, vaccine hesitancy, adherence to social distancing, COVID-19 testing, and mental health.

CONCLUSIONS

At this time, the future of self-reported symptom tracking for COVID-19 is unclear. Some sources have speculated that COVID-19 may become a yearly occurrence much like the flu, and if so, the data that these programs generate is still valuable. However, it is unclear whether the public will maintain the same level of interest in reporting their symptoms on a regular basis if the prevalence of COVID-19 becomes more common.

Published: June 2021

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for pain management during recovery from orthopaedic surgery. NSAID use is associated with increased risk of bone healing complications but it is currently unknown whether NSAIDs increase the risk of developing an orthopaedic-device-related infection (ODRI) and/or affects its response to antibiotic therapy. The present study aimed to determine if administration of the NSAID carprofen [a preferential cyclooxygenase-2 (COX-2) inhibitor] negatively affected Staphylococcus epidermidis (S. epidermidis) bone infection, or its subsequent treatment with antibiotics, in a rodent ODRI model. Sterile or S. epidermidis-contaminated screws (~ 1.5 x 106 CFU) were implanted into the proximal tibia of skeletally mature female Wistar rats, in the absence or presence of daily carprofen administration. A subset of infected animals received antibiotics (rifampicin plus cefazolin) from day 7 to 21, to determine if carprofen affected antibiotic efficacy. Bone changes were monitored using in vivo µCT scanning and histological analysis. The risk of developing an infection with carprofen administration was assessed in separate animals at day 9 using a screw contaminated with 102 CFU S. epidermidis. Quantitative bacteriological analysis assessed bacterial load at euthanasia. In the 28-day antibiotic treatment study, carprofen reduced osteolysis but markedly diminished reparative bone formation, although total bacterial load was not affected at euthanasia. Antibiotic efficacy was negatively affected by carprofen (carprofen: 8/8 infected; control: 2/9 infected). Finally, carprofen increased bacterial load and diminished bone formation following reduced S. epidermidis inoculum (102 CFU) at day 9. This study suggests that NSAIDs with COX-2 selectivity reduce antibiotic efficacy and diminish reparative responses to S. epidermidis ODRI.

Investigation and Design of Dual Gate Dielectrically Modulated Junction less TFET for Biomolecule Recognition
Authors: Tomar Ms. Aishwarya
Published: June 2021

This paperwork includes a tunnelling transistor with dual gate and employing the use of dielectric modulation (DG-DM-JL-TFET) based structure. In order to recognize the biomolecule like protein, biotin, uricase etc a nano cavity is presented above the tunnelling. Charge plasma technique is used to form the drain and source regions into the substrate. High work function creates a hole in source and similarly a lower work function will create an electron in drain. The “N” region is etched into the substrate using hafnium electrode with a work function of 3.9 eV. Si02 of 0.5nm thickness is inserted between electrode of source. The “P+” region is etched on intrinsic silicon substrate using Platinum electrode having a work function of 5.93 eV. The device structure proposed in this paper shows results for sensitivity for charged and neutral biological molecules. The sensitivity of the biological molecules having higher dielectric constant is greater than those biological molecules possessing lower dielectric constant.

Authors: Teja P Sai
Published: June 2021

Unsolicited e-mail also known as Spam has become a huge concern for each e-mail user. In recent times, it is very difficult to filter spam emails as these emails are produced or created or written in a very special manner so that anti-spam filters cannot detect such emails. This paper compares and reviews performance metrics of certain categories of supervised machine learning techniques such as SVM (Support Vector Machine), Random Forest, Decision Tree, CNN, (Convolutional Neural Network), KNN(K Nearest Neighbor), MLP(Multi-Layer Perceptron), Adaboost (Adaptive Boosting) Naïve Bayes algorithm to predict or classify into spam emails. The objective of this study is to consider the details or content of the emails, learn a finite dataset available and to develop a classification model that will be able to predict or classify whether an e-mail is spam or not.

A Novel Deep Convolutional Neural Network for Tuberculosis Detection
Authors: Abidi Syed Farhan Hyder
Published: June 2021

India accounts for the world’s largest number of cases in TB, with 2.8 million cases annually, and accounts for more than a quarter of the global TB burden. Tuberculosis (TB) is caused by the bacterium (Mycobacterium tuberculosis) which most commonly affects the lungs. TB is transmitted from person to person through the air. When people with TB cough, sneeze or spit, the germs are propelled into the air. This paper showcases a methodology which uses a Deep Learning Model (dCNN) for the detection of Tuberculosis in the lungs. The accuracy obtained by the methods for the model is desirable and dependable, which is increasingly productive in contrast to the accuracy shown by other neural networks.

Authors: Hartati Sri , Fitriani Hani , Taryana Nanang , Nawawi Nawawi , Cahyani Yani , Kurniawati Siti , Sudarmonowati Enny
Published: June 2021

Background: This study aimed to evaluate the growth ability of cassava mini stem cuttings with different node number and a variety of stem cutting shapes and their correlation with starch content in the stems at initial growth stages. Methods. In this study, the viability of cassava stem cuttings was identified in two type experiments i.e. mini-stem cuttings consisting 1 and 2 nodes and shape variation of single node mini-stem cutting. Parameters observed were shoots emergence period, number of sprouting cuttings, shoots number  of individual stem cuttings, shoots height and number of leaves. In addition, starch histochemical test was  also carried out on stems of young shoots and initial stem cuttings using Lugol’s solution. Results. Both cassava stem cuttings consisting of 1 and 2 buds indicated the same survival rate of 100%. 1 bud stem cuttings with different shapes showed different survival rate, i.e. 60-80% for semicircular and fully circular cuttings and 30-40% for box shape cuttings. The difference in survival rate with different stem size is probably related to the availability of the amount of starch to support shoots growth. Observations at week 3 after planting generally showed that the stem cuttings with 2 buds were higher than those of stem with 1 bud. Conclusion: There were differences in the scores on the starch content test qualitatively with Lugol staining, in various parts of the plant originating from 1 bud and 2 bud cuttings which may indicate a breakdown of starch during shoot development.

How does power distance belief influence consumers' new product acceptance? Life satisfaction and social demonstrance as moderators
Authors: Li Qing , Chen Siyun
Published: June 2021

Scholars have not yet established how power distance belief (PDB) influences consumers' new product acceptance. We examined the relationship between PDB and new product acceptance (i.e., consumers' preference and attitude), along with the moderating roles of life satisfaction and social
demonstrance, and the mediating role of need to belong. Through three studies, our findings show that when life satisfaction was low, consumers with low (vs. high) PDB had a more favorable attitude toward the new products and showed a stronger preference for them. Further, need to belong was
a principal mechanism inducing the influence of PDB and life satisfaction on new product acceptance, with the interaction effect being stronger among consumers with high (vs. low) social demonstrance. Our investigation makes important theoretical contributions by expanding the PDB literature,
and also has practical implications for marketers in their promotion of new product acceptance. For example, marketers could sell new products in cultures with low PDB or use advertisements to remind consumers of the importance of equality. This will help to prime consumers with low PDB when
their life satisfaction is low, thereby enhancing their attitude toward new products.
Optimal Multi-port-based Teleportation Schemes
Authors: Mozrzymas Marek , Studziński Michał , Kopszak Piotr
Published: June 2021

In this paper, we introduce optimal versions of a multi-port based teleportation scheme allowing to send a large amount of quantum information. We fully characterise probabilistic and deterministic case by presenting expressions for the average probability of success and entanglement fidelity. In the probabilistic case, the final expression depends only on global parameters describing the problem, such as the number of portsN, the number of teleported systemsk, and local dimensiond. It allows us to show square improvement in the number of ports with respect to the non-optimal case. We also show that the number of teleported systems can grow when the numberNof ports increases aso(N)still giving high efficiency. In the deterministic case, we connect entanglement fidelity with the maximal eigenvalue of a generalised teleportation matrix. In both cases the optimal set of measurements and the optimal state shared between sender and receiver is presented. All the results are obtained by formulating and solving primal and dual SDP problems, which due to existing symmetries can be solved analytically. We use extensively tools from representation theory and formulate new results that could be of the separate interest for the potential readers.

Published: June 2021

El objetivo de este artículo es revisar el contexto mundial, y especialmente el colombiano, respecto al manejo de los residuos de equipos eléctricos y electrónicos, su aprovechamiento, recuperación y los principales métodos para la extracción de metales base y preciosos de alto valor agregado. Para ello, se realizó una revisión bibliográfica para obtener las cantidades de residuos, sus componentes principales y los métodos de extracción de metales base y preciosos; para Colombia, se realizó un estudio de caso, en el que, mediante un proceso de hidrometalurgia aplicado a teléfonos celulares, se calcularon las cantidades de metales base y preciosos que se pueden obtener. Se encontró que solo se aprovecha el 15,5 % de los residuos electrónicos en el mundo, que los principales componentes reciclables son el hierro (Fe), el cobre (Cu), el aluminio (Al), el plomo (Pb), el níquel (Ni), la plata (Ag), el oro (Au) y el paladio (Pd), y que el uso de los residuos electrónicos como fuente de metales podría reducir el consumo de energía entre 60 % y 95 %. Para el estudio de caso en Colombia, se encontró que se podrían obtener 3,8 t/año de Cu, 3,5 t/año de Fe, 56,5 kg/año de Ag, 6 kg/año de Pd y 10 kg/año de Au. Se concluye que es viable la recuperación de metales a partir de residuos eléctricos y electrónicos y que se deben buscar alternativas para aprovecharlos debido a su potencial valor agregado.
Formação Pedagógica e o Ensino-Aprendizagem de Programação: Um estudo preliminar
Authors: Berssanette João Henrique , De Francisco Antonio Carlos
Published: June 2021

A literatura tem evidenciado que os docentes, ao ensinar programação, têm obtido menos êxito do que deveriam e precisariam ter. Nessa direção, considerando que pelo menos uma parte das dificuldades relativas ao processo de ensino-aprendizagem de programação pode estar relacionada à formação pedagógica ou à ausência dela pelos docentes, objetivou-se, neste estudo, por meio de duas diferentes abordagens investigar uma possível relação entre a formação pedagógica e o ensino-aprendizagem de programação. Para tanto, foi desenvolvido um estudo exploratório de abordagem qualitativa. Por intermédio da análise dos dados coletados, observou-se que os docentes com formação pedagógica possuem uma percepção positiva da preparação fornecida pelo ensino superior para exercer a docência, quando em comparação aos docentes que não possuem essa formação. Ademais, pode-se verificar que não há diferenças significativas no que tange aos índices de aprovação entre os docentes com e sem formação pedagógica.

Busca-se compreender e identificar as origens, estratégias, habilidades desenvolvidas e os desafios e potencialidades do Pensamento Computacional (PC) na Educação Básica. Por meio de uma Revisão Sistemática da Literatura, compreendemos que: (1) quando se aplica conceitos do PC com estratégias didático-pedagógicas condizentes; (2) quando se chega ao entendimento de que a programação de computadores não está restrita a profissionais da Computação, mas pode ser aplicada nas séries iniciais para que se desenvolva habilidades espaciais, de raciocínio e de resolução de problemas e de aptidões cognitivas; (3) quando se parte da compreensão de que alunos em situações vulneráveis, geralmente, prosperavam nos ambientes computacionais, ponderamos que compreensão crítica e aprofundada sobre o PC com propostas exequíveis para a formação de professores, aliada a organização curricular e a estratégias didático-pedagógicas incluindo métodos de avaliação da aprendizagem, consistem em elementos fundamentais para agregar contribuições na formação básica dos alunos para o século XXI.
The determinants of banks’ capital adequacy ratio: Evidence from Western Balkan countries
Authors: Keqa Flamur
Published: June 2021

This research aims to evaluate the impacts of liquidity, profitability, size, loans and capital structure on banks’ capital adequacy ratio (CAR) in the Western Balkan region using annual data from 103 commercial banks operated in Western Balkan countries for the period between 2010 and 2018. Panel data fixed effect method is employed. The data comprises of a total 51 observations for panel least squares. The empirical findings obtained panel data regression show that profitability proxies by the return on asset (ROA) have the largest impact on CAR among other financial ratios. In addition, liquidity and size have statistically significant positive effects in determining capital adequacy ratio for the banks in the region, unlike leverage ratio. However, the leverage ratio has a negative impact on the capital adequacy ratio. The policy implications of this study suggest that in order to accomplish requirements for capital adequacy expectations are to have good indicators in regard to performance, liquidity and size.

Este artigo tem o intuito de refletir sobre a presença dos povos indígenas nos territórios urbanos, em especial os Guarani Mbya, localizados na zona noroeste da cidade de São Paulo, destacando a importância da preservação e estruturação dos territórios indígenas para a reprodução e a sobrevivência de suas culturas. Para essa reflexão, partiremos de uma revisão bibliográfica com o objetivo de entender as noções de território indígena  e território urbano, contrapondo a ótica guarani de ocupação e reprodução com a ótica capitalista de se articular no espaço. Na sequência, olharemos para a presença dos povos indígenas na cidade de São Paulo e seus desafios, observando, em particular, os Guarani Mbya com seu modo de viver e ocupar a terra, para ressaltar as formas de violência e os processos de exclusão aos quais esses povos foram submetidos, que, todavia, resistem e sobrevivem na cidade.
O compromisso regional das universidades comunitárias por meio da extensão
Authors: Fioreze Cristina , Moretto Clenir Maria , Henrich Giovana
Published: June 2021

A extensão constitui-se, historicamente, na mediação pela qual as universidades comunitárias regionais tecem vínculos com a comunidade. Este artigo, apoiado em pesquisa de campo, estuda a extensão nas instituições comunitárias face à concorrência mercantil que passaram a vivenciar recentemente. Analisa as feições assumidas pela extensão no modelo comunitário: ainda está centrada nas demandas por desenvolvimento de suas comunidades regionais? Ou os rearranjos ocorridos em nome da sobrevivência econômico-financeira fragilizam essas características? Trabalha-se com as noções de bem público e privado na educação superior e com o conceito de capitalismo acadêmico na nova economia. Evidencia-se um deslocamento do modelo institucional para uma extensão capaz de se sustentar financeiramente, o que não significa o total afastamento do compromisso com demandas da comunidade. A curricularização dessa dimensão mostra-se potente para revitalizar uma extensão comprometida com o bem público, capaz de reaproximar as IES comunitárias regionais do compromisso social que marca sua origem.

La pandemia del machismo: Masculinidades en tiempos del COVID-19
Authors: Bustillos Diego
Published: June 2021

El presente artículo tiene como objetivo analizar los elementos para reflexionar esta coyuntura de la pandemia del Coronavirus desde la masculinidad y brindar herramientas que nos permitan afrontar esto desde una manera más positiva pero también más proactiva desde una perspectiva de futuro en la que nuestras prácticas se traduzcan en culturas donde el cuidado , la paz , la afectividad y la igualdad sean elementos centrales en nuestra vida como hombres. Pienso que esta crisis sanitaria además de mostrar nuestro sistema de salud precario ha evidenciado el machismo que impera en el Perú , que es tan grave como esta pandemia  , sin embargo no se le ha puesto la atención debida .De esta manera, considero que es indispensable percibir el cómo esta cuarentena , como factor de riesgo ha reforzado los comportamientos machistas y los roles de género de la sociedad peruana, pero también a la vez  debería ser  una oportunidad para cuestionarnos y deconstruirnos entre nosotros.
