Published: August 2021

Objetivou-se avaliar a variabilidade do estado de humor de atletas de Basquetebol durante uma competição. Participaram 27 atletas de Basquetebol, do mesmo clube, do sexo masculino, com idade entre 13 e 15 anos. Todos responderam a Escala de Humor de Brunel em seis jogos durante o campeonato. Os resultados demonstraram que os atletas investigados apresentaram, durante toda a competição, elevados escores de vigor, e baixaram os escores de confusão mental e tensão. Enquanto variabilidade, os atletas não apresentaram variabilidade durante a competição, ou seja, mantiveram-se com níveis elevados de humor positivo. Pode-se concluir que essa amostra apresentou o perfil de humor denominado de iceberg, durante toda competição.

It can safely be said that the colonial period ushered a new era of Sīrah-writing in the Indian subcontinent. A number of biographies of the Prophet (PBUH) were written in response to the works of Orientalists on Sīrah. In this wake, many Urdu biographers employed traditional and innovative methodologies in their biographies of the Prophet (PBUH). One such innovation was the usage of sacred scriptures of other religions in their biographies. This article studies the prophecies about the Prophet (PBUH) in Judeo-Christian scriptures and the ways in which Urdu biographers of the Prophet (PBUH) utilized them in their works.

Published: August 2021

With the growth of the construction market, it is necessary to develop new products. Taking this into account, this article proposes a study using recycled plastic in the development of porous floors for civil construction. The intention is to reduce the volume of this solid waste in the city and in the landfill, in addition to using less natural resources, such as wood and steel. For the development of the work, plastic bottles were used pets, in addition, the materials developed were tested in the laboratory, in which the necessary criteria were raised for eventual approval of the same. The results show that 99.5% of the water passes through the material developed, which is a very satisfactory result. The results achieved with respect to abrasion resistance, limpability, chemical resistance to attack and surface appearance were equally favorable. Therefore, it was observed that the material developed is suitable for use in the function of porous floors, besides contributing to the reduction of plastic waste in the city, to allocate this waste and to use less natural resources. These results prove that the product would be adequate to aid in urban drainage, since it would contribute to the surface runoff, and would also reduce the volume of solid waste.

Published: August 2021

The purpose of this study was to analyze and quantify spectral parameters, the absorption bands, specifically in the uv-visible region of some N-oxide ligands. From the spectra, the area under the absorption band, the molar absorptivity, the integrated absorption coefficient and the oscillator strength by the Gaussian approximation method were calculated for each of them, using the proposed evaluation by Drago and Figgs. According to the obtained results, it can be concluded that the heterocyclic compounds studied absorb very well electromagnetic radiation in the ultraviolet region. For the ligands QUI-NO and NIC-NO it was observed that there are two types of bands, primary and secondary, being transitions of type π → π * and n → π*, respectively. For DITBIS-NO, there was only one primary band (transition 1) and two additional shoulders, which had the highest observed absorbance coefficient. These ligands are expected as potential electron donors in complex systems whose purpose is to change the energy levels of the electronic system in order to promote a better utilization of the absorbed energy and therefore a better efficiency.

This work presents a low cost, simple and adequately reliable electrochemical alternative for the determination of uric acid in human serum in comparison to the enzymatic colorimetric reference method. The quality of the electrochemical measurements was assessed by comparing its uncertainty with a target value of 0.56 mg dL-1 and the measurements were carried out by the standard addition method. The modified working electrode consists of 25% lignin, 60% nanocarbon, 15% mineral oil and electrodeposited metallic copper. The uncertainty of measurement was estimated by the bottom-up approach, from which uncertainty components were combined by applying the uncertainty propagation law (LPI), the numerical method of Kragten and the Monte Carlo Simulation Method (MCM). The analytical procedure was successfully applied in the analysis of physiological sera added at 1.0, 3.0, 5.0, 7.0 and 9.0 mg dL-1 of AU and for two other samples of human saline. The results of the measurements carried out for the different serum samples using the proposed method, associated to the different methods for estimating the uncertainty, showed sufficiently low and metrologically equivalent values, in which the results were shown to be compatible with the estimated reference values.

Currently, resistance to antibiotics has become a problem for the treatment of infectious diseases. In this study, silver nanoparticles were synthesized using the aqueous extract of Palo santo (Burseragraveolens), for its biocide action, in order to determine its antimicrobial effect on Escherichia coli and Staphylococcus aureus. Different concentrations of nanoparticles (100 until1000 ppm) were evaluated at contact times of 1, 2, 5 and 10 minutes for 1500 and 15000 CFU/mL. Additionally, to determine effectiveness, disc diffusion tests using various concentrations of nanoparticles (500-1000 ppm) were performed on S.aureus and K. pneumoniae. According to the results of antimicrobial effect for E.coli, the effectiveness of nanoparticles can be established at all contact times for 1500 CFU from 800 ppm and for 15000 CFU from 400 ppm. With S.aureus, total inhibition was showed from 800 ppm in 1500 CFU at 5 minutes of contact and between 500-1000 ppm with 15000 CFU at minute one. S. aureus and K.pneumoniae tests showed sensitivity with nanoparticles. The average of susceptibility for S.aureus had the lowest inhibition between 500-600 ppm and the highest at 700-800 ppm. The average susceptibility for K. pneumoniae is more constant in terms of inhibition at 600-1000 ppm. This study demonstrated the antimicrobial effect of silver nanoparticles synthesized under the specified conditions.

The hydantoin and thiohydantoin heterocycles are present in a wide range of biologically active compounds including therapeutic drugs for the treatment of seizures and anti-tumor compounds. Thiohydantoins, have also been used as anti-convulsant agents and are present in fungicides, herbicides and natural products. However, the principal current interest comes from the application of thiohydantoins for the treatment of prostate cancers. Structural characterization of hydantoin and thiohydantoin are important to comprehend their effect mechanisms because of their considerable biological effects. In this work a thiohydantoin derivative, 1-acetyl-5-(2-methylpropyl)-2-thioxo-imidazolidin-4-one (I), has been obtained by the reaction of 2-amino-4-methylpentanoic acid with KSCN in acetic anhydride-acetic acid mixture. The heterocyclic compound was characterized by FTIR, NMR, powder and single-crystal X-ray diffraction analysis. This compound crystallizes in the triclinic system, space group P-1 (Nº2), Z=4, with two independent molecules in the unit asymmetric. The thiohydantoin (I) forms one-dimensional hydrogen bonded chains, via a single hydrogen bond between the carbonyl oxygens and the amine ring N3 position, that run along [100] direction, with graphset motif C(6). The nature of intermolecular interactions has been analyzed through Hirshfeld surfaces and 2D fingerprint plots.

With increasing contamination of water by various pollutants, which makes this resource increasingly scarce and unfit for use, there is a need to develop new treatment methods that are accessible, efficient, renewable and do not produce polluting waste that degrades the environment. Due to this the use of natural adsorbents has become one of the most investigated alternatives for the treatment of waters whether for the removal of organic or inorganic pollutants. This work aims to study the adsorption potential of a natural adsorbent from acerola seed by means of column chromatography to adjust the total hardness of groundwater after the characterization of physicochemical parameters such as pH, electrical conductivity, Turbidity, total dissolved solids, chlorides, alkalinity and total hardness. The adsorbent samples before and after being used for the treatment were characterized by infrared absorption spectroscopy (FTIR), scanning electron microscopy (SEM). The use of the natural adsorbent obtained from the acerola seed was very effective for the treatment of hardness of the analyzed.

Published: August 2021

The statement of cash flows is one of the required financial statements of public companies, and thus is required of all accounting majors. After learning the other required financial statements in an introductory financial accounting course and, again, in the first intermediate accounting course, accounting majors learn how to prepare the statement of cash flows in the second or last intermediate accounting course. Most accounting majors find the statement of cash flows significantly more difficult to learn than any other financial statements. Especially, students find it most difficult to understand the indirect method of preparing the statement of cash flows. Preparing the statement of cash flows using the indirect method, students go through the most difficult time, specifically, doing the adjustments that are made to net income to reconcile to cash flows from operating activities.In this paper, presented is a different way to explain the principles of indirect method of preparing the statement of cash flows with a focus on the reconciliation of net income to cash flows from operating activities. Different from the explanations in the textbooks available in the market, the approach presented in the paper is preferred by all the students who were taught the statement of cash flows. Also, pointed out in the paper are a few things that students are easily confused of in learning the statement of cash flows.
A Systematic Review of Qualitative Studies on Residential Consumer Experience with Smart Meters and Dynamic Pricing
Authors: Buckley Penelope
Published: August 2021

La littérature qualitative concernant l’étude de l’expérience des consommateurs avec les compteurs intelligents, ainsi que les incitations qui y sont associées, est analysée afin d’identifier les barrières à leur acceptation et à leur adoption. L’acceptation est un élément clé car les ménages doivent d'abord être prêts à installer des compteurs intelligents chez eux. L'adoption permet quant à elle de savoir si ces dispositifs peuvent être efficaces. Parmi les barrières identifiées, il y a le fait que les ménages ne font pas confiance aux compagnies d'énergie. Ils ne savent pas comment agissent les compteurs intelligents et comment ils peuvent les utiliser à leur profit. Ils trouvent que la tarification dynamique est complexe et lorsqu'ils ont le choix, peu d’entre eux optent pour cette tarification. L’effet sur la consommation de ces dispositifs est souvent de courte durée, les économies monétaires étant rarement suffisamment élevées pour encourager des changements de comportement persistants et les ménages étant contraints de faire un feedback selon leur niveau de confort personnel – sur lequel ils ne sont pas prêts à faire des compromis – et les rigidités de leur vie quotidienne. Grâce à cette analyse, différents segments cibles de consommateurs de ces compteurs intelligents sont identifiés.

An air disaster is a tragic event, usually brutal and unforeseeable, which often involves human and material losses. The investigation of such events requires extraordinary measures in order to apply state-of-the-art forensic technology, aiming to identify both the causes of the accident and the victims. Forensic dentistry is among the most important methods of identification, as it allows the use of techniques that can identify an individual based on the systematic study of corpses or bone remains, physiological and hereditary aspects, and, the specific variations of a person's teeth.

The aim of this paper is to review the available elements that can be used within the field of forensic dentistry to identify corpses and bone remains in the event of an air disaster.
Security in smart objects, a general view at the physical and logical level
Authors: Rodríguez Fabián Geovanny Cuzme
Published: August 2021

In this research we addressed an issue of big importance with regard to information and computer science security. Within this area, we know that security is framed within the CIA triangle, which refers to confidentiality, integrity and availability of information or objects connected to the Internet, a subject that should be treated with great awareness. There were some questions that we inevitably must ask in order to understand at a deeper level the different aspects of information security, such as: What is an object? How safe is our private information? What privacy settings do we have? We live in an interconnected world where most of devices at home, businesses, industries, organizations, and cities are connected to the Internet. Within that environment, these objects are fulfilling some functionality that facilitates the lives of each individual, although making them somehow dependent on this technology with a high degree of risk to which they are exposed. This study aimed to explain and demonstrate that most of electronic devices or intelligent objects that are developed, locally or overseas, do not have a proper design with regard to making information security a first priority, then, proposing a guiding scheme that allows an adequate development cycle of intelligent objects. The study concluded that we are not 100% safe, as well as cyber-attacks will continue to evolve, so the conception of information security will have to evolve as well.
Smuggling reduction of gas cylinders through the implementation of radio frequency identification technology
Authors: Revelo Marco David , Montenegro Victor Javier
Published: August 2021

Ecuador subsidizes fuels, the problem with this benefit is that, many citizens are dedicated to illegally market these resources in border cities,

among these fuels there are the cylinders of liquefied petroleum gas; the existing fragile control greatly benefits smuggling, representing a loss of resources for Ecuador.

 

There is no subsidy in neighboring countries such as Peru and Colombia, and unfortunately some citizens have chosen to engage in illegal fuel marketing, generating economic losses for the country. The actual cost of a 15 kilo gas cylinder is 12.00 dollars, however, it is sold at 1.60 dollar. It means that the government subsidizes 89% of the price of gas, with barely 11% being paid by consumers. (Diario el Comercio, 2013)

 

People who take advantage of the poor control of illegal marketing, reduce the number of cylinders in border areas of Ecuador and therefore increase the price, this situation has generated inconveniences for Ecuadorian citizens when they can not acquire gas cylinders. Currently, given the advance of technology in particular of microelectronics, it is very common to use portable electronic devices such as RFID (Radio Frequency Identifier) tags, for this project the active labels of 2.4 GHz allow the unique identification of each gas cylinder, as well as the portability of the information and the relation of belonging between gas cylinders and citizens, facilitating their monitoring and control.

The purpose of this study was to investigate the relationship between mental toughness (MT) and emotional intelligence (EI) of Turkish and American professional basketball players in Turkish Professional Leagues. The population target was 156 participants (x̄age=24,35±5,48) from Turkish citizens, and 42 participants (x̄age =27,69±3,15) from USA citizens and a total of 198 professional basketball players participated from 17 professional teams. Participants completed "Sports Mental Toughness Questionnaire (SMTQ)" developed by Scheard et al. (2009) and "Emotional Intelligence Scale for use in Sport (EISS)" developed by Let al.t al (2009). One-Way ANOVA test was utilized in order to examine the influence of an independent variable (citizenship) on dependent variables. The relation between emotional intelligence (EI) and mental toughness (MT) was analyzed through Pearson Product-Moment Correlation Coefficient technic (p <0.05). According to the results, significant differences were observed between citizenship variable in terms of EI and MT. In addition, a linear positive correlation was found while examining the relationship between the EI and MT subscales, EI social skills subscales and the MT constancy subscales. As a result of research, Turkish athletes have a higher of social skills score in terms of citizenship variables, while American players have better appraisal of others' emotions score. In addition, American citizens showed higher mean in terms of constancy and control subscales. The results also showed that the increase in MT constancy subscale scores causes the increase in EI social skills subscale scores.

Academic Literacies as Cornerstones in Course Design: A Partnership to Develop Programming for Faculty and Teaching Assistants
Authors: Bury Sophie , Sheese Ron
Published: August 2021

We discuss an educational development approach to embedding academic literacies instruction within disciplinary curricula. This developmental, embedded approach contrasts with the generic, extra-curricular, study-skills approach adopted in many universities. Learning Commons partners at York University, including librarians, writing instructors, and learning skills counsellors, collaborated with educational developers in the York Teaching Commons to design a program for course instructors and teaching assistants (TAs) who seek to improve their students’ academic literacies. This program includes interactive workshops focusing on strategies to facilitate the redesign of courses and assignments so as to give explicit attention to process-related practices and abilities involved in library research and writing. The academic theory underpinning this program is outlined along with its key content elements. We also describe how the program draws on SPARK (Student Papers and Academic Research Kit), an online resource, created by the York Learning Commons under a Creative Commons license with the goal of helping students succeed with written academic assignments. Feedback from instructors and TAs support that the program has played an important role in helping them to question their assumptions and redesign their teaching practice.
Developing Scholarly Identity: Variation in Agentive Responses to Supervisor Feedback
Authors: Inouye Kelsey , McAlpine Lynn
Published: August 2021

The central task for doctoral students, through the process of writing, feedback and revision, is to create a thesis that establishes their scholarly identity by situating themselves and their contribution within a field. This longitudinal study of two first-year doctoral students investigated the relationship between response to supervisor feedback on the thesis proposal and the development of scholarly identity (self-confidence, independence in research thinking, positioning the self in relation to others), through the lens of individual agency (self-assessing work, seeking and critically engaging with others’ feedback in order to clarify research thinking). Data consisted of semi-structured interviews conducted over 3 months, different drafts of the research proposal, and written supervisor comments on the drafts. Narrative analysis and open coding were used to produce in-depth portraits of the individual experiences and perceptions of each participant. There were differences between the two individuals in their growing scholarly identities as regards their agency. The degree of agency exhibited in engaging critically with feedback in relation to self-assessment, and clarifying research thinking appeared linked to the development of the student’s scholarly identity: her sense of confidence, scholarly independence in thinking, and positioning in relation to others. Such confidence and ownership in turn inspired greater agency. Interestingly, differences in the extent to which participants were agentive in relation to feedback appeared influenced by previous experiences with feedback. These results contribute a richer understanding of the relationship between use of supervisor feedback and growing scholarly independence.

Writing and Identity: A Narrative Inquiry on Two Saudi Arabian ESL Females
Authors: Hersi Mustafa A.
Published: August 2021

Writing in a second language is considered extremely challenging for several reasons. Concerns that perplex second-language learners include cognitive complications, the composing process, building arguments, and constructing an identity as a writer. Cultural issues related to writing also pose problems for second-language writers This paper focuses exclusively on how international students, female Saudi ESL students, construct their writing identity in the ESL milieu and navigate critical issues in cross-cultural writing. This paper explores how two ESL Saudi Arabian female students in an English program in the United States negotiate and construct their identities while writing in English. The study will also investigate challenges faced by those students in acquiring English writing skills and how those challenges inform their thinking and shape or reshape their identities as writers. 

The study involves two female Saudi students who are studying the English language at a mid-size diverse Southwest public university in the United States. The researcher collected the data through semi-structured interviews with the participants and then performed a textual analysis of their responses. The researcher transcribed and analyzed the data and describes the results thematically herein. The findings of this study augment our understanding in how female Saudi ESL students construct their identities as writers. The analysis covers some sociocultural factors that shape their writing. The paper concludes with pedagogical implications for ESL teachers and suggestions for future study.

Com o objetivo de  discutir as interferências sobre as questões etnico-raciais no contexto da América Latina e os desdobramentos para os processos de (in)exclusão da população afrodescendente, a partir dos relatórios e documentos dos organismos internacionais, realizou-se estudo bibliográfico e documental. As discussões foram articuladas com Munanga (2015), Goes e Silva (2013), Sousa, (2009), Gentili (2001) e Barreto (2009), além de outros. A partir do estudo é possível perceber que, apesar de conquistar a liberdade, no contexto da América Latina, a população afrodescendente ainda sofre com as mazelas históricas que negam e invisibilizam a cultura e os aspectos históricos que provocaram tal exclusão. Nos documentos dos Organismos Internacionais encontram-se informações que ora denunciam as situações de (in)exclusão presentes na América Latina e ora fazem indicações/recomendações para desencadear pretensas ações visando os processos inclusivos dos afrodescendentes, porém alinhadas aos interesses do capitalismo.

Planejar o arranjo físico ou layout é uma maneira de melhorar o desempenho das organizações em termos de custos, utilização de espaço e fluxo de operações, adequando equipamentos, pessoas e materiais no ambiente de produção. Portanto, o objetivo deste artigo é propor melhorias ao arranjo físico de um ambiente de produção de joias através do método Systematic Layout Planning – SLP. Esse método auxilia nas decisões sobre como organizar e posicionar equipamentos e pessoal dentro do espaço disponível por meio de atividades inter-relacionadas. Assim, realizou-se um estudo de caso de natureza aplicada e descritiva, com coleta de dados por meio de entrevistas semiestruturadas e de observação direta. A análise e interpretação dos dados foi conduzida de forma qualitativa de acordo com as fases do método SLP. Como resultado, foram feitas propostas de layouts e, respeitando as necessidades da organização analisada, apontou-se a mais adequada.
Nonlinear homogeneous dynamical system of fully cracked concrete beam
Authors: Mohan G. , Pandey U.K.
Published: August 2021

Purpose: Purpose of this paper is the theoretical formulation of elasto-dynamics behaviour of fully cracked concrete beams for two-degree of freedom (DOF) dynamical system. Such modelled system is demonstrated by a new class of two-DOF conservative, fully-nonlinear systems known as nonlinear homogeneous dynamical (NHD) systems. Design/methodology/approach: The theoretical formulation of Two-DOF dynamical system has been developed by using the fundamental concept of structural analysis. Further, the behaviour of such class of conservative dynamical system has been concluded by using MATLAB. Findings: Findings can be distinguished into two aspects. First, when subjected to service loads, reinforced concrete structures possess tension cracks. Due to load variation with time leads the breathing action (opening-closing-reopening) of existing cracks and the behaviour of such structures are nonlinearly-elastic. Second, such class of fully nonlinear dynamical system possess dependence of stiffness coefficients on nodal displacements. Research limitations/implications: The mechanism behind such class of fully nonlinear dynamical system is not yet fully explored. Practical implications: Practical implications are related to the structural response of fully cracked concrete beam to different earthquake excitation, especially to understand the response of such nonlinear homogeneous elasto-dynamical system with two-DOF concrete beam. Originality/value: Elasto-dynamics of fully cracked concrete beams.
Free vibration behaviour of thin-walled concrete box-girder bridge using Perspex sheet experimental model
Authors: Verma V. , Nallasivam K.
Published: August 2021

Purpose: Curved box-girder bridges offers an excellent solution to the problems associated
with traffic congestion. However, owing to their complex geometry, they are subjected to
shear lag, torsional warping and cross-sectional distortion, which must be assessed in
their study and design. Furthermore, the dynamic behaviour of curved bridges adds to the
complexity of the issue, emphasizing the importance of studying free vibration. The purpose
of this study is to numerically model the concrete curved box-girder bridge considering
torsional warping, distortion and distortional warping effects and to identify key parameters
that influence the free vibration response of the box-girder bridge by validating it with
experimental and analytical studies.
Design/methodology/approach: The concrete bridge is numerically modelled by
means of computationally effective thin-walled box-beam finite elements that consider
torsional warping, distortion and distortional warping, which are prominent features of thinwalled
box-girders. The free vibration analysis of the concrete curved box-girder bridge is
performed by developing a finite element based MATLAB program.
Findings: The identification of critical parameters that influence the free vibration behaviour
of curved thin-walled concrete box-girder bridges is one of the main findings of the study.
Each parameter and its effect has been extensively discussed.
Research limitations/implications: The study limits for the preliminary design phase
of thin-walled box-girder bridge decks, where a complete three-dimensional finite element
analysis is unnecessary. The current approach can be extended to future research using
a different method, such as finite element grilling technique on multi-span curved bridges
having unequal span.
Swarm Behaviour Optimisation Methods Based on an Original Algorithm
Authors: FALKOWSKI Krzysztof , DUDA Michał
Published: August 2021

This article presents an authorial swarm algorithm that performs coverage tasks using the Sweep Coverage method. The presented solution assumes stochastic movement of the objects in the swarm which allows them to be simple ones. Our goal was to find an optimal number of objects in the swarm. The main evaluated factors are time and energy consumption. Changing input data allowed us to designate different cases and to examine the influence of varying parameters of a single boid on a whole swarm behaviour.

Published: August 2021

In this article, the authors mentioned the function of short-recoil-operated weapons with a vertical sliding-wedge breechblock. The dynamic simulation was conducted and then the results were compared with the corresponding experimental data to verify reliability of the model. The model is calculated and tested out on the 37 mm twin anti-aircraft gun. Besides, the article presents the effect of some structural parameters on functionality of the automatic weapon. The reported results are an important theoretical basis to determine the rate of fire and the forces acting on the guns. The movement of the breechblock also affects stability of the weapon and can therefore be used to a math model or to simulate the movement of the weapon. Calculated and verified data could be used for the design of an automatic firing system as well as for solving vibration on automatic guns when burst firing.

Micromelum minutum is used widely in traditional folk medicine. Although this species has been investigated extensively and several bioactive compounds have been isolated, little work has been done on Indonesian M. minutum. This research aimed to study the chemical constituents and biological activities of M. minutum cultivated in Bantimurung Bulusaraung National Park, South Sulawesi, Indonesia. The isolated compounds were assessed for their cytotoxicity towards MCF-7 and 4T1 cell lines by MTT method. The dried ground leaves of M. minutum were sequentially macerated with n-hexane, ethyl acetate, and methanol. The n-hexane and ethyl acetate extracts contained a flavonoid 5,7-dihydroxy-3,4',8-trimethoxyflavone (1) which inhibited MCF-7 and 4T1 cell viability by 50% at concentrations of 369±8 and 227±5 µM, respectively. Further separation of the ethyl acetate extract by column chromatography yielded acetyldihydromicromelin A (2) and a mixture of dihydromicromelin A (3) and dihydromicromelin B (4), which were not active toward MCF-7 and 4T1 cells.
Welding Distortion Prediction for Multi-Seam Welded Pipe Structures using Equivalent Thermal Strain Method
Authors: Wu Chunbiao , Wang Chao , Kim Jae-Woong
Published: August 2021

Distortion prediction of a welded structure is an important way to improve work efficiency and ensure product quality during the fabrication process. Recently, the widely used approaches for evaluating residual deformation include the thermo-elastic-plastic finite element method (TEP-FEM) and the inherent strain method (ISM). The former can accurately simulate the entire welding process with excessive computational time, whereas the latter has great potential in the fast prediction of residual distortion in complex welded components. In this study, an equivalent thermal strain method based on inherent strain theory was proposed to predict residual deformation of the multi-seam welded pipe structures. Moreover, a full 3D TEP-FEM model was also developed to estimate the distributions of inherent strain in longitudinal (L-seam) and circumferential (C-seam) welds. To validate the accuracy of the proposed ISM, the welding distortion predicted by the proposed ISM is compared with the experimental data and TEP-FEM simulation results. It is discovered that the proposed ISM can be used to accurately predict welding-induced deformation in multi-seam welded pipe structures. Furthermore, compared with TEP-FEM simulation, the significant advantage of this approach is that the computing efficiency can be increased by about 50 times.
Evaluation of the Synergistic Effects of Ciprofloxacin and Low-Power Laser on Apoptosis, Cell Viability, and Reactive Oxygen Species Levels in Skin Cancer (A375 Cancer Cells)
Authors: Saleki Baghban Shahrzad , Zarrabi Ahrabi Nakisa , Tabaie Seyed Mehdi
Published: August 2021

Background: Skin cancer is one of the most common diseases. Ciprofloxacin creates free radicals and causes DNA damage, and due to the chromophore nature of this drug, the production of free radicals increases. Low-power laser (LPL) is the inhibition of red and near-infrared light to tissues to repair injuries and lesions created to heal wounds and connective tissue and treat acute and chronic pain. Objectives: The aim of this research was to investigate the synergistic effects of ciprofloxacin and LPL on apoptosis, cell viability, and reactive oxygen species (ROS) levels in skin cancer (A375 cancer cell lines). Methods: The viability rate of A375 cancer cell lines treated with ciprofloxacin and LPL was evaluated by microscopic and MTT methods, and then flow cytometry was used to evaluate their effects on apoptosis and ROS levels. Statistical analysis was done using one-way ANOVA. Results: Treatment of cancer cells with ciprofloxacin (100 μg/mL) and LPL for 30 seconds could prevent the process of cancer cell proliferation after 48 and 72 hours. Also, the combination of these two methods increased the rate of cellular apoptosis by 5% and reduced ROS levels by 0.1%. Conclusions: Because the combination of ciprofloxacin and LPL therapy can stop the proliferation of cancer cells, especially skin cancer cells thus, the use of this treatment can be used to treat cancer in the future.
