Effects of Affected Side One Leg Standing Training with PNF Sprinter and Skater Patterns on the Balance and Gait Function in Hemiplegic Patients
Authors: Eun Ikhwan , Nam Seungmin
Published: October 2021

This study was conducted to investigate the effect of affected side one leg standing training with PNF sprinter and skater patterns, which have a pattern like that of actual gait, on the balance function and gait function of chronic hemiplegic patients due to stroke. 23 inpatients diagnosed with stroke due to hemiplegia at a rehabilitation hospital located in South Korea. The patients were randomly divided into a experimental group and a control group. The experimental group performed PNF Sprinter and Skater Pattern training, and the control group performed balance pad training. Each group was trained for 30 minutes three times a week for six weeks. Static balance was measured using Biorescue, while dynamic balance was measured using the TUG. Gait function was measured using 10MWT, 6MWT. Both groups exhibited statistically significant improvements in static and dynamic balance function after the training (p<.05). The experimental group exhibited statistically significant increases in gait function after training (p<.05). A significant difference was observed between the two groups (p<.05). One leg standing training on the affected side using the PNF sprinter and skater patterns resulted in significant improvement in both balance and functional performance of gait in hemiplegic patients due to chronic stroke.

Published: October 2021

Until recently, the establishment of a universal test, allowing the early cancer detection by the analysis of blood, urine or other biological fluids seemed as realistic as the development of "Perpetuum mobile". There are numerous obstacles on this road: above all being the ultra-low concentrations of biomarkers shed by such tumors in the bloodstream. Meanwhile, in attempts to create such a test, the methodology of ultrasensitive DNA analysis has emerged, and stunning practical successes have been achieved in this field over the past few years. The performance of the CancerSEEK test has already reached the threshold for clinical utility of its practical implementation. Techniques based on the analysis of methylation patterns (Galleri test, cfMeDIP-seq) are also rapidly developing. A number of promising studies are based on quite unconventional approaches, for example, the analysis of tumor-associated viral or microbial DNA sequences circulating in plasma. In addition to universal tests aiming at the detection of any or many types of neoplasms in older people, the methods for early DNA-based detection of certain cancer types in selected high-risk groups are being developed. These advances finally make the prospects for introducing liquid biopsy into routine cancer screening look like a matter of the near future.
Modern view on the classification of neuroendocrine neoplasms of stomach
Authors: Peregorodiev Ivan , Bokhian Vagan , Delektorskaya Vera , Safonova Anna
Published: October 2021

Neuroendocrine neoplasms (NEN) of the stomach include a heterogeneous group of neoplasms characterized by different pathogenetic mechanisms, metastatic potential, and prognosis. The incidence of gastric NAN has increased 15-fold over the past few decades. It is necessary to clearly distinguish between well-differentiated neuroendocrine neoplasms (NETs) of the stomach and neuroendocrine cancer (NECs) of the stomach, as well as mixed neuroendocrine-non-neuroendocrine neoplasms.
To date, there are three classifications that are used in clinical practice: clinicopathological classification, WHO classification, and UICC TNM classification. It should be noted that over the past five years, these classifications have undergone important changes. In the clinicopathological classification, in addition to the existing three types, a number of authors proposed to add the 4th type (developing as a result of inadequate functioning of the proton pump) and the 5th type (developing in patients who receive long-term therapy with proton pump inhibitors). In the 2019 WHO classification, an important change is the acceptance that well-differentiated NETs can have a high degree of malignancy – Grade III. The main changes in the 8th edition of the TNM classification concerned the differentiation of the M symbol.
Thus, to date, the classification of gastric NENs allows us to accurately characterize tumor staging, the pathogenesis underlying their development, and prognosis. They form the basis for choosing an adequate treatment strategy that makes possible to achieve the most favourable result.

Published: October 2021

Introduction. Silver nanoparticles due to its pronounced cytotoxicity are regarded as promising agent for anticancer therapy. Determination of normal and transformed cells sensitivity to silver nanoparticles can be the basis for the application as an adjuvant cancer treatment.
The objective of the study was to investigate influence of atomic clusters of Argentum (ACA) in the form of silver bisilicate nanoparticles colloid solution on viability and proliferation of human myeloma cell line, mesenchymal stromal cells and blood lymphocytes.
Material and methods. Cell viability was evaluated by MTT and LDH assay. Cell proliferation was evaluated by flow cytometry.
Results. It was found that ACA had dose-depending cytotoxicity toward all investigated cell types, but normal and transformed cells varied significantly in the sensitivity to nanoparticles. IC50 for myeloma cell line RPMI8226 was 1,75 µg/ml. For MSCs of different origin IC50 was in the range of 12 to 16 µg/ml. ACA in concentration from 2 to 3 µg/ml induced RPMI8226 cells metabolic disruption and death without influence on viability and cell cycle of mesenchymal stromal cells and blood lymphocytes.
Conclusion. Results of work has shown distinct differences in sensitivity to ACA between myeloma cells, mesenchymal stromal cells and blood lymphocytes. The optimal range of ACA concentration with anticancer effect without cytotoxic influence on normal cells has been determined in vitro.
Portréty na mincích pergamských vládců / Portraits on coins of the rulers in Pergamon
Authors: Mašek Michal
Published: October 2021

During the rule of Alexander III the Great (BC 336–323) and after his death, unified coins circulated all over the entire Hellenistic world. The silver tetradrachms have head of Heracles on their obverse. After the Alexander´s death and after the royal proclamation of some Diadochi, portraits of the particular living rulers started to appear on obverse of the subsequent coins. The tetradrachms of the rulers in the Kingdom of Pergamon represented an exception. The coins showed only dead rulers. But the unique tetradrachm with portrait of Eumenes II (alive in time of production) seems to be a special case in the mentioned system.

Tri neznáme typy keltských mincí zo stredných Čiech / Three unknown types of the Celtic coins from central Bohemia
Authors: Fröhlich Július
Published: October 2021

Reportedly in 2018, three Celtic coins of unpublished types were found in the territory of central Bohemia. The first type is represented by a gold 1/8-stater, reportedly discovered on unknown location of the Kolín district. Its new iconography is confirmed by the reverse image of the sitting figure holding an object of the disc form in front and a stick bent in form of the reversed letter ‘U’. Based on the typological features, it is possible to judge that the coin was produced in horizon of the middle La Tène Period LT C1. Two remaining types of the Celtic coins are represented by one obol with image of standing bird (?) / horse and one obol with image of boar protoma (?) / horse. Both coins reportedly come from the south-east outer bailey of the Závist oppidum, and they were very likely produced during the late La Tène Period LT D1a.

Published: October 2021

In hochbelasteten Bereichen von Flachdecken werden häufig Unterzüge geringer Höhe angeordnet, um die einwirkende Gesamtquerkraft sowohl über die Unterzüge als auch über die Platte abzutragen. Trotz eines in der Realität fließenden Übergangs zwischen Querkraft- und Durchstanzeinwirkung sind die Anwendungsgrenzen für beide Nachweise normativ strikt voneinander getrennt. Zur notwendigen Aufteilung der Gesamtquerkraft auf Unterzug und Platte sowie zur Festlegung des zu führenden Nachweises bei Flachdecken mit integrierten Unterzügen geringer Höhe wurde eine Parameterstudie auf Basis einer numerischen Berechnung durchgeführt. Die Unterzugshöhe und das Stützweitenverhältnis der Platte wurden hierbei als maßgebende Einflussfaktoren auf das Tragverhalten identifiziert. Darauf aufbauend wurde ein ingenieurmäßiger Berechnungsansatz abgeleitet, der eine Aufteilung zwischen den Querkraftanteilen in der Platte und im Unterzug auf Basis der Plattenschnittgrößen an definierten Auswertungspunkten und -schnitten im FE-Modell ermöglicht. Zudem wurden Bemessungsdiagramme zur vereinfachten Abschätzung der Querkraftanteile von Unterzug und Platte sowie der entsprechenden Nachweisschnitte in der Platte entwickelt.

Published: October 2021

Será que o papel japonês é o material mais adequado para o facing de pintura sobre tela? Seria benéfica a utilização de papéis específicos adequados a cada caso? Este estudo procurou dar resposta a estas questões e dar a conhecer, dos papéis testados, qual o mais adequado ao facing em pintura a óleo sobre tela. Para o efeito, foram executadas maquetes, de três cores diferentes. Em cada cor foram realizadas duas texturas, uma lisa e outra empastada. Foram também definidas, em cada cor e textura, três áreas: duas para aplicação de dois vernizes distintos e outra para permanecer sem verniz. As maquetes foram realizadas para que se obtivessem todas as combinações dos materiais anteriormente descritos e cada papel foi testado em cada uma destas combinações.Realizados os ensaios e analisados os resultados, concluiu-se que, dos materiais testados, o papel japonês nem sempre foi o mais eficaz, tendo sido superado pelo Wet-strength Tissue, um papel celulósico, por demonstrar facilidade de aplicação, pela resistência do papel e pela perda de fibras.

Published: October 2021

Low-cost nanoscale copper hexacyanoferrate (CuHF), a good selective adsorbent for cesium (Cs+) removal, was prepared using the chemical co-precipitation method. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and high-resolution transmission electron microscopy (HR-TEM) were conducted to determine the CuHF morphology. Copper hexacyanoferrate, Cu13[Fe(CN)6]14.(2K).10H2O, has a cubic structure (space group F-43m) in the range of 10-30 nm and a Brunauer-Emmett-Teller (BET) surface area of 462.42 m2/g. The removal of Cs+ and Sr2+ is dependent on pH; the maximum adsorption capacity (qmax) of CuHF is achieved at a pH = 6. From the Langmuir model, qmax = 143.95 mg/g for Cs+ and 79.26 mg/g for Sr2+, respectively. At high concentrations, Na+, Ca2+, and K+ ions have very little effect on Cs+ removal, and Na+ and K+ ions have a higher affinity for removing Sr2+ than Ca2+ at all concentrations. CuHF has a high affinity for alkaline cations in the order: Cs+ > K+ > Na+ > Ca2+ > Sr2+, as proposed and discussed.
On Optimizing WiFi RSSI and Channel Assignment using Genetic Algorithm for WiFi Tuning
Authors: Apavatjrut Anya , Kamdee Sathianporn
Published: October 2021

In this work, we proposed a genetic algorithm-based Wi-Fi-tuning platform that could facilitate the network administrators to cope with co-channel interference triggered by other wireless sources. Generally, with a well-designed WLAN, signal interference from adjacent areas is usually minimized. Unfortunately, when other wireless sources are introduced into the WLAN system, co-channel interference is inevitable. Interference usually causes degradation and/or disruption of network services. Resolving this issue becomes even more complicated when the interfering signals come from access points owned by other ISPs and are not accessible by the network administrators. This paper proposed a Wi-Fi tuning platform that allowed automatic reconfiguration of WLAN settings by finding the best settings for channel assignment and transmission power level. When signal interference is detected, the platform attempts to find heuristic solutions for wireless settings based on a genetic algorithm. From our experiments, we could see that our proposed algorithm could regenerate WLAN settings that provided stronger signal levels, higher coverage ranges while reducing interference levels in the deployment area. With the proposed platform, troubleshooting became less complicated, requiring less cost and time. With the help of the Wi-Fi tuning platform, the network administrators could promptly react to the incidence leading to the enhancement of availability, reliability, and consistency of the WLAN system.

An Impact Study of Hymnody on Selected Ghanaian Churches
Authors: Afriyie Edwin
Published: October 2021

This paper is an investigation of the efficacy of hymns and their impact on personality. The investigation was aimed at addressing ‘the problem of the relationship of hymnody and discipline, self-regulation which results in guarded behaviour reflecting in speech, personal appearance, and conduct within the Ghanaian society.’ The investigation was against the backdrop of the perception that hymnody influences devoted singers with the power to shape personality and bring about character transformation. The objective of the investigation was to spike the hymnody effect within society. The theory of personal transformation combined the qualitative design. The study consisted of a single question to determine the most predominant view about hymnody in hymn-singing churches in Accra and Kumasi. Findings indicated that 41% of 300 informants confirmed hymnody as powerful and transformative, but elitist and excluded the non-literate. Eurocentric and Afrocentric perspectives attended the analysis of Hymnody. The study concluded that hymnody is beneficial to mood and character change to stimulate the transformation of soul and mind, leading to the growth of the inner man as a function of discipline. Thus, a reference to the notions of pedagogy and discipline are underscored as transforming outcomes of devoted hymnody participation. The paper’s contribution to knowledge lies in its focus on the role of hymnody, a religious ritual, as catalyzing the development of the discipline ethic to engage the attention of the academy for further research.

Probiotic candidates among dairy Lactobacilli and Streptococcus thermophiles strains for control of the oral pathogen Porphyromonas gingivalis
Authors: Michaylova Michaela , Yungareva Tsvetelina , Urshev Zoltan , Dermendzieva Yana , Yaneva Blagovesta , Dobrev Iliyan
Published: October 2021

Introduction: The gram-negative bacterium Porphyromonas gingivalis is a major causative agent of periodontitis in adults. It is also associated with disorders of the cardiovascular and endocrine systems, rheumatoid arthritis, pancreatic cancer, and Alzheimer’s disease. Lactic acid bacteria (LAB) present in the oral cavity or introduced as probiotic preparations can support successful treatment of periodontitis due to their antagonism with the pathogen.

Aim: The aim of this study was in vitro assessment of the antimicrobial activity of Lactobacillus spp. and Streptococcus thermophilus against P. gingivalis.

Materials and methods: The antimicrobial effect of lactobacilli or S. thermophilus from the LBB Culture collection against P. gingivalis DSM 20709 was evaluated with the well diffusion assay on Wilkins Chalgren blood agar. Inhibition of the pathogen was evaluated by measuring the diameter of clear zones around the wells.

Results: Application of milk fermented with selected LAB resulted in а bacteriostatic effect. The most active culture was S. thermophilus 187/4, followed by L. delbr. ssp. bulgaricus (LBB.B1054, C3/2 and LBB.B120), L. helveticus LBB.H48/1 and L. rhamnosus I-1/13. The respective reconstituted freeze-dried preparations had a stronger inhibitory effect on the pathogen with the formation of clear bactericidal zones. The effect of milk acidified with lactic acid was apparent with minimal bactericidal zone observed at concentration of 0.1%. The effectiveness of the assay was confirmed with Elgydium and Eludril.

Conclusions:P. gingivalis DSM 20709 was sensitive to the metabolites produced in fermented milk by selected strains of L. delbr. ssp. bulgaricus, L. helveticus, L. rhamnosus, and S. thermophilus. Reconstituted freeze dried fermented milk had а stronger inhibitory effect compared to fresh samples. Lactic acid produced by lactic acid bacteria was the key component for inhibition of the pathogen.

Published: October 2021

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital disorder affecting female reproductive system (agenesis of uterus and upper part of vagina) alone (type 1), or associated with abnormalities of other organs and systems (type 2). We report a case of a 21-year-old woman diagnosed with MRKH due to primary amenorrhea during puberty and operated for formation of neovagina. She was admitted to the Department of Urology with abdominal pain and oligoanuria, where the physical examination and imaging studies revealed a malformation of the upper urinary tract: a solitary dystopia of kidney in the pelvis with stenosis of ureteropelvic junction and hydronephrosis. After initial desobstruction with a DJ stent, a pyeloplasty was performed. Females with primary amenorrhea are often delayed with the diagnosis of potential MRKH syndrome, and those diagnosed with the syndrome should undergo detailed examination to exclude concomitant urinary abnormalities.

Authors: Dimov Petar , Hurtig Jennie , Georgiou Konstantinos , Theodorou Dimitrios , Marinov Blagoi , Enochsson Lars
Published: October 2021

Introduction: Video games have a positive impact on the skills required for laparoscopic surgery. Several studies have assessed the impact of video games on laparoscopic skills.

Aim: This study aims to systematically review the existing evidence.

Materials and methods: A search strategy was implemented to retrieve relevant articles from MEDLINE and SCOPUS databases. The retrieved articles were reviewed for further evaluation according to the predetermined inclusion/exclusion criteria.

Results: Twenty-six studies were included in this systematic review. These included prospective (n=9), retrospective (n=5) and interventional (n=12). Other review papers were cited in the discussion section. Studies with positive outcomes significantly outweighed the negative ones (21 vs. 5, respectively).

Conclusions: Although there is some evidence that video game experience could give some advantage in laparoscopy no firm conclusions could be drawn yet. The reasons for that lay in the various aims, approaches and results of different study reports. Gaming could be used as a daily warm-up or as a tool to speed-up mastering new skills. A standardized protocol is needed for answering the different questions regarding the impact of video game exposure to laparoscopic skills development and progression.

Published: October 2021

Two new species of wood wasps (Anaxyelidae), Orthosyntexis elegansgen. et sp. nov. and Orthosyntexis thantisp. nov., are described from mid-Cretaceous Kachin amber. Orthosyntexisgen. nov. exhibits characters and character combinations unique to the family, such as the combination of two mesotibial spurs, a length ratio of forewing 1Rs to 1M<1, a length to width ratio of forewing cell 1mcu ≥ 2, and the presence of 2M+Cu in the hind wing. The new species and morphological characters allow for an exploration of anaxyelid phylogeny. The phylogenetic results indicate that Anaxyelidae are monophyletic and it is suggested to classify the genera in two subfamilies, Syntexinae and Anaxyelinae, the latter including Kempendajinae and Dolichostigmatinae.

The main result is the continuity of the solution map on the set of admissible parameters. Its application to the parameter identification problem is considered.
Blurred boundaries: A flexible approach for segmentation applied to the car market
Authors: Grigolon Laura
Published: October 2021

Prominent features of differentiated product markets are segmentation and product proliferation blurring the boundaries between segments. I develop a tractable demand model, the Ordered Nested Logit, which allows for asymmetric substitution between segments. I apply the model to the automobile market where segments are ordered from small to luxury. I find that consumers, when substituting outside their vehicle segment, are more likely to switch to a neighboring segment. Accounting for such asymmetric substitution matters when evaluating the impact of new product introduction or the effect of subsidies on fuel‐efficient cars.
Neighborhood effects and housing vouchers
Authors: Davis Morris A. , Gregory Jesse , Hartley Daniel A. , Tan Kegon T. K.
Published: October 2021

Researchers and policy makers have explored the possibility of restricting the use of housing vouchers to neighborhoods that may positively affect the outcomes of children. Using the framework of a dynamic model of optimal location choice, we estimate preferences over neighborhoods of likely recipients of housing vouchers in Los Angeles. We combine simulations of the model with estimates of how locations affect adult earnings of children to understand how a voucher policy that restricts neighborhoods in which voucher‐recipients may live affects both the location decisions of households and the adult earnings of children. We show the model can nearly replicate the impact of the Moving to Opportunity experiment on the adult wages of children. Simulations suggest a policy that restricts housing vouchers to the top 20% of neighborhoods maximizes expected aggregate adult earnings of children of households offered these vouchers.

Instructional Design, Educational Technology, and LGBTQ Students
Authors: Justice Lenora Jean , Hooker Steven D.
Published: October 2021

As diversity and social justice have become more important in education, educators are beginning to realize that their lessons, both real and virtual, need to be more inclusive. More specifically, this chapter addresses the culture, learning, and relationship with technology of a specific subset of students: individuals who identify as lesbian, gay, bisexual, transsexual/transgender, and queer/questioning (LGBTQ) or who have LGBTQ parents, guardians, friends, and/or family. Suggestions for educators on inclusive strategies when integrating technology into lessons through digital activities and various educational technology tools, as well as inclusive instructional design suggestions, are included. As for the question addressed in the title, none is the answer because all three of these things belong together in all forms of education, in all types of schools, and by all types of educators.
Case Study for Counseling Same Sex Couples Through the Fertility Process
Authors: Rausch Meredith A. , Wikoff Haley D.
Published: October 2021

Fertility and reproductive technologies are increasingly important topics for counseling LGBT+ individuals. As legislation improves, lesbian couples have additional opportunities to expand their families. Professional counselors may be aware of the various fertility methods (e.g., artificial insemination, in vitro fertilization), but may lack understanding of the specific differences inherent in the process for two females. Lesbians also face barriers present in a heteronormative society. This chapter describes a counseling relationship with a lesbian couple who are working through the fertility process. When performing counseling work, using the multicultural and social justice competencies allows the counselor to provide ethical practice. The counselors use Relational-Cultural Theory, a feminist theory, to help Jane and Kelsey set goals consistent with the tenets of the theory. Additionally, the counseling team and couple work through the unique barriers a lesbian couple faces when experiencing the fertility process in a heteronormative society.

Published: October 2021

This chapter focuses on the experiences of participants in an intergenerational art program for LGBTQIA+ audiences, which takes place at the Museum of Contemporary Art, Tucson (MOCA). In this chapter, the authors outline the impetus and purpose of this program. They consider the impact that it has had on LGBTQIA+ individuals and the formation of an intergenerational community. From combating loneliness to creating connections across generations, this program invites individuals into the museum space who identify as LBTQIA+ but rarely have the opportunity to connect with one another. Facilitators and participants design projects and gallery activities that promote engagement through dialogue and art-making. As such, art provides connections that give participants opportunities to share and learn from one another. Contemporary art and the museum become sites for engagement. Gallery activities and art-making allow participants to experiment with a range of materials and learn new skills through humor, play, creative inquiry, and collaboration.
A Latter-Day Sodom and Babylon
Authors: Endong Floribert Patrick C.
Published: October 2021

This chapter examines the manner in which Nigerian bloggers and web journalists interpreted, framed and represented Obama's gay rights diplomacy in Nigeria. The chapter specifically explores the extent to which these web journalists' interpretations of the American pro-gay movement generated new religion-inspired representations of the U.S. government and Americans on the social networks. The study is based on a quantitative and qualitative content analysis of over 162 online articles generated by Nigerian citizen journalists in reaction to Obama's gay rights advocacy in Nigeria and Africa. It answers the following research questions: how did Nigerian web/citizen journalists frame Obama's pro-gay move? What was their tone?

Body Image and Emotional Well Being Among Gay and Heterosexual Religious Young Men
Authors: Fisherman Shraga
Published: October 2021

This chapter attempts to create a close-up picture of the society of Orthodox Jewish men in regard to their levels of religiosity and sexual identity. The author examines BI, emotional wellbeing, and the connection between them, among three groups of religious Israeli young men: Modern Orthodox (MO) heterosexual men, Modern Orthodox gay men (MOG), and ultra-Orthodox heterosexual men (UO). The findings pose an extremely important challenge to educators in Israel. The young men answered two questionnaires: SWLS and the Body Image Questionnaire. The BI and wellbeing scores for the MOGs were significantly lower than for the MOs and UO. The correlations between BI and wellbeing were different in each group: there was no significant correlation among the MO, among the MOGs there was a negative, medium, and significant correlation, and among the UO there was a positive, high, and significant correlation. These differences were explained by social and educational trends.

Published: October 2021

The chapter explores and describes community participation in the National Development Plan through Primary Health Care by using case studies of LGBT organizations in South Africa. Post-Apartheid and democratic South Africa has endorsed community participation as one of the fundamental pillars of the public Primary Health Care approach in its governance structures. This chapter focuses on the current major health issue in South Africa, the HIV epidemic, which is one of the leading causes of death in the country. Particular attention is paid to members of the LGBT community because of their discrimination in public healthcare facilities on grounds of their sexual orientation. The chapter relies on secondary sources of data collection from extant literature, textbooks, journal articles, and internet sources. Challenges to address LGBT community discrimination in HIV testing, prevention, treatment, care, and support were identified and solutions to uphold their human rights were proffered. These solutions are based on the principles of social justice, inclusion, diversity, and equality.

Authors: Natarajan Elango , Razif Muhammad Rusydi Muhammad , Faudzi AAM , Palanikumar K.
Published: October 2021

Soft actuators are generally built to achieve extension, contraction, curling, or bending motions needed for robotic or medical applications. It is prepared with a cylindrical tube, braided with fibers that restrict the radial motion and produce the extension, contraction, or bending. The actuation is achieved through the input of compressed air with a different pressure. The stiffness of the materials controls the magnitude of the actuation. In the present study, Silastic-P1 silicone RTV and multi-wall carbon nanotubes (MWCNT) with reinforced silicone are considered for the evaluation. The dumbbell samples are prepared from both materials as per ASTM D412-06a (ISO 37) standard and their corresponding tensile strength, elongation at break, and tensile modulus are measured. The Ogden nonlinear material constants of respective materials are estimated and used further in the finite element analysis of extension, contraction, and bending soft actuators. It is observed that silicone RTV is better in high strain and fast response, whereas, silicone/MWCNT is better at achieving high actuation.

Authors: Carnevale Marcos Vinícius Ramos , Filho Armando Carlos de Pina
Published: October 2021

The use of robotics in the industrial environment has, in general, very similar goals. Because of productivity requirements, or due to reliability, industries have been constantly equipping their floor with robots. In that sense, the chapter observed—in a fiberglass company—the chance of using a robot to execute a boring and repetitive task. The task mentioned is, actually, the manufacturing of fiberglass reinforced plastic (FRP) molded grating. To confirm the possibility of using a robot to this job, a cost and time analysis was made about the whole molded gratings manufacturing process. Afterward, research about robotics was taken in parallel with the conception of the robot (named “roving-robot”). Calculations were made to the mechanical project of the robot. Applying computer-aided design (CAD), technical drawing and bill of materials were generated to permit the robot assembling. All of these project steps are presented in this chapter.

A Literature Review on Automation Testing Using Selenium+Sikuli
Authors: Lathwal Ashish
Published: October 2021

Automation testing is a methodology that uses an application to implement the entire life cycle of the software in less time and provides efficiency and effectiveness to the testing software. In automation testing, the tester writes scripts and uses any suitable application software to test the software application. Automation is basically an automated process that is comprised of lots of manual activities. In other words, automation testing uses automation tools like Selenium, Sikuli, Appium, etc., to write test script and execute test cases, with no or minimal manual involvement required while executing an automated test suite. Usually, automation testers write test scripts and test cases using any of the automation tool and then groups test several cases. Here, we will discuss a neat case study explaining the automation testing using a hybrid test script.
