Using the Veggie Meter in Elementary Schools to Objectively Measure Fruit and Vegetable Intake: A Pilot Study
Authors: Martinelli Sarah , Acciai Francesco , Tasevska Natasha , Ohri-Vachaspati Punam
Published: May 2021

Self-reported fruit and vegetable (FV) consumption in children has limitations that could be overcome with objective measures that are easy to implement. The Veggie Meter (VM) is a non-invasive portable device that measures skin carotenoid levels, a concentration biomarker of usual FV intake. While VM has been used to measure FV consumption in adults, few studies have explored its use in elementary school settings. Designing research studies using the VM with elementary school-age children requires an understanding of how well this device can be used in a school setting and of the distribution of VM scores in this population. We used VM to measure skin carotenoids in a diverse sample of 143 elementary school children who also answered commonly asked questions about consumption frequency of FV the previous day. Multivariable regression was used to assess the independent association of demographic variables with VM scores. VM scores were also compared with student-reported FV intake. There was a weak but statistically significant correlation between reported frequency of total vegetable consumption the previous day and observed VM scores (r = 0.174, p = 0.042). This study provides an example of the successful use of the VM in a school setting to collect an objective measure of FV intake and provides important description of data that can inform future studies.

Melissa officinalis is a medicinal herb with an extensive pharmacological profile that has been proven to have beneficial effects in oral and gastrointestinal disorders. However, the effects of this plant in oral, pharyngeal, and colorectal malignancies, types of cancer with an increased incidence in recent years, are less investigated. The present study aims to evaluate the pharmacological profile of a Melissa officinalis total extract for potential benefits in oral, pharynx and colorectal carcinoma. The LC-MS profile of MO total extract (MOte) indicated a rich content in polyphenols, data that support the potent antioxidant capacity exhibited and the antimicrobial activity against both Gram-negative and Gram-positive bacteria. In addition, MOte triggered a dose-dependent and selective decrease in the viability of tumor cells (tongue and pharynx squamous cell carcinomas, and colorectal adenocarcinoma), with the most significant effect being recorded at 100 μg/mL. At the same concentration, MOte exhibited an antiangiogenic effect by inhibiting the process of angiogenesis in ovo. Overall, our findings support the potential benefits of Melissa officinalis leaf total extract as a valuable candidate for the prophylaxis of oral, pharyngeal and colorectal neoplasms.
Coming Up Short: The Catholic Church’s Pastoral Response to the Transgender Crisis in America
Authors: Roy-Steier Stephanie
Published: May 2021

The Vatican and United States Conference of Catholic Bishops (USCCB) have issued official responses to the phenomenon of gender diversity, as well as instructions for the education and care of transgender and gender diverse (TGD) people in America. However, have these authorities effectively utilized current sociological research to develop and implement contextually appropriate pastoral practices that are lifegiving and to the greatest benefit of this at-risk population? This article argues that they have not and that their recommendations have been linked to increased harm and marginalization. Utilizing Richard Osmer’s framework for practical theological interpretation, this article begins with an overview of the Magisterium’s guidance, followed by a summary of quantitative data gleaned from national surveys, population studies, and demographic analyses that reveals unique experiences of suffering and oppression. The middle sections bring in leading theories and findings from social, health, and medical fields, which illustrate TGD needs and vulnerabilities and expose the Magisterial offices’ dangerous failure to meet or even acknowledge them. The final sections call for a revised pastoral approach grounded in the concrete situations of TGD people and congruent with the Church’s commitment to love, service, and social justice. Good practice models and ethical norms are suggested for immediate incorporation into care and praxis.
“Black Ovaries”: An Uncommon Case of First Systemic Recurrence of Melanoma
Authors: Cazzato Gerardo , Colagrande Anna , Arezzo Francesca , Resta Leonardo , Ingravallo Giuseppe
Published: May 2021

Here we describe a rare case of a 48-year-old woman with a previous history of malignant melanoma (pT2a pathological stage, IB clinical stage) occurring about five years previously. She complained of abdominal pain and pelvic discomfort, diagnosed as a consequence of a bilateral ovarian solid masses completely occupying the recto-uterine space. She underwent laparotomy surgery with total hysterectomy and bilateral salpingo-oophorectomy. Gross examination of the excised material revealed an unusual grey-black bilateral ovarian tumor; a histopathological diagnosis of ovarian bilateral metastatic melanoma was made. Imaging study (CT/MRI) did not reveal metastasis in other zones of the body. Melanoma metastasis usually affects the skin, liver, brain and lungs, and rarely gynecological localizations. On the other hand, most bilateral ovarian tumors are comprised of serous carcinoma, mature teratoma and gastrointestinal carcinoma metastasis. Exceptionally, primary ovarian melanoma may arise in mature ovarian cystic teratomas.

Authors: Trujillo José Antonio , de-la-Bandera Isabel , Palacios David , Barco Raquel
Published: May 2021

The arrival of the Fifth Generation (5G) entails a significant evolution in the context of mobile communication networks. This new technology will bring heterogeneous scenarios with new types of services and an increasingly high number of users and nodes. The efficient management of such complex networks has become an important challenge. To address this problem, automatic and efficient algorithms must be developed to facilitate operators’ management and optimization of their networks. These algorithms must be able to cope with a very high number of heterogeneous data and different types of scenarios. In this paper, a novel framework for a cellular network behavioral analysis and monitoring is presented. This framework is based on a combination of unsupervised and supervised machine learning techniques. The proposed system can analyze the behavior of cells and monitor them, searching for behavior changes over time. The information extracted by the framework can be used to improve subsequent management and optimization functions.
Smart Cities of the Future as Cyber Physical Systems: Challenges and Enabling Technologies
Authors: Puliafito Antonio , Tricomi Giuseppe , Zafeiropoulos Anastasios , Papavassiliou Symeon
Published: May 2021

A smart city represents an improvement of today’s cities, both functionally and structurally, that strategically utilizes several smart factors, capitalizing on Information and Communications Technology (ICT) to increase the city’s sustainable growth and strengthen the city’s functions, while ensuring the citizens’ enhanced quality of life and health. Cities can be viewed as a microcosm of interconnected “objects” with which citizens interact daily, which represents an extremely interesting example of a cyber physical system (CPS), where the continuous monitoring of a city’s status occurs through sensors and processors applied within the real-world infrastructure. Each object in a city can be both the collector and distributor of information regarding mobility, energy consumption, air pollution as well as potentially offering cultural and tourist information. As a consequence, the cyber and real worlds are strongly linked and interdependent in a smart city. New services can be deployed when needed, and evaluation mechanisms can be set up to assess the health and success of a smart city. In particular, the objectives of creating ICT-enabled smart city environments target (but are not limited to) improved city services; optimized decision-making; the creation of smart urban infrastructures; the orchestration of cyber and physical resources; addressing challenging urban issues, such as environmental pollution, transportation management, energy usage and public health; the optimization of the use and benefits of next generation (5G and beyond) communication; the capitalization of social networks and their analysis; support for tactile internet applications; and the inspiration of urban citizens to improve their quality of life. However, the large scale deployment of cyber-physical-social systems faces a series of challenges and issues (e.g., energy efficiency requirements, architecture, protocol stack design, implementation, and security), which requires more smart sensing and computing methods as well as advanced networking and communications technologies to provide more pervasive cyber-physical-social services. In this paper, we discuss the challenges, the state-of-the-art, and the solutions to a set of currently unresolved key questions related to CPSs and smart cities.
Determination of Folic Acid Using Biosensors—A Short Review of Recent Progress
Authors: Di Tinno Alessio , Cancelliere Rocco , Micheli Laura
Published: May 2021

Folic acid (FA) is the synthetic surrogate of the essential B vitamin folate, alternatively named folacin, pteroylglutamic acid or vitamin B9. FA is an electroactive compound that helps our body to create and keep our cells healthy: it acts as the main character in a variety of synthetic biological reactions such as the synthesis of purines, pyrimidine (thus being indirectly implied in DNA synthesis), fixing and methylation of DNA. Therefore, physiological folate deficiency may be responsible for severe degenerative conditions, including neural tube defects in developing embryos and megaloblastic anaemia at any age. Moreover, being a water-soluble molecule, it is constantly lost and has to be reintegrated daily; for this reason, FA supplements and food fortification are, nowadays, extremely diffused and well-established practices. Consequently, accurate, reliable and precise analytical techniques are needed to exactly determine FA concentration in various media. Thus, the aim of this review is to report on research papers of the past 5 years (2016–2020) dealing with rapid and low-cost electrochemical determination of FA in food or biological fluid samples.
Strain Transfer Function of Distributed Optical Fiber Sensors and Back-Calculation of the Base Strain Field
Authors: Yoon Sangyoung , Yu Meadeum , Kim Eunho , Yu Jaesang
Published: May 2021

Distributed optical fiber sensors are a promising technology for monitoring the structural health of large-scale structures. The fiber sensors are usually coated with nonfragile materials to protect the sensor and are bonded onto the structure using adhesive materials. However, local deformation of the relatively soft coating and adhesive layers hinders strain transfer from the base structure to the optical fiber sensor, which reduces and distorts its strain distribution. In this study, we analytically derive a strain transfer function in terms of strain periods, which enables us to understand how the strain reduces and is distorted in the optical fiber depending on the variation of the strain field. We also propose a method for back-calculating the base structure’s strain field using the reduced and distorted strain distribution in the optical fiber sensor. We numerically demonstrate the back-calculation of the base strain using a composite beam model with an open hole and an attached distributed optical fiber sensor. The new strain transfer function and the proposed back-calculation method can enhance the strain field estimation accuracy in using a distributed optical fiber sensor. This enables us to use a highly durable distributed optical fiber sensor with thick protective layers in precision measurement.
Impact of Safety Message Generation Rules on the Awareness of Vulnerable Road Users
Authors: Lara Tomás , Yáñez Alexis , Céspedes Sandra , Hafid Abdelhakim Senhaji
Published: May 2021

In the face of cooperative intelligent transportation systems (C-ITS) advancements, the inclusion of vulnerable road users (VRU), i.e., pedestrians, cyclists, and motorcyclists, has just recently become a part of the discussion. Including VRU in C-ITS presents new challenges, most notably the trade-off between the increase in VRU safety and the aggravation in channel congestion resulting from VRU-generated messages. However, previous studies mainly focus on network-related metrics without giving much consideration to VRU safety-related metrics. In this context, we evaluated such a trade-off with a study of motion-based message generation rules for VRU transmissions. The rules were analyzed using theoretical and simulation-based evaluations. In addition to studying the message generation rules using channel load metrics, such as channel busy ratio (CBR) and packet delivery ratio (PDR), we introduced a new metric: the VRU Awareness Probability (VAP). VAP uses the exchange of messages from active VRU to measure the probability of VRU detection by nearby vehicles. Results show that fixed message-filtering mechanisms reduce the overall channel load, but they could negatively impact VRU detection. We established the importance of quantifying the VRU awareness and its inclusion in C-ITS analysis because of its direct impact on VRU safety. We also discussed approaches that include VRU context and dynamism to improve the definition of message generation rules.

Published: May 2021

Clinicians lack objective means for monitoring if their knee osteoarthritis patients are improving outside of the clinic (e.g., at home). Previous human activity recognition (HAR) models using wearable sensor data have only used data from healthy people and such models are typically imprecise for people who have medical conditions affecting movement. HAR models designed for people with knee osteoarthritis have classified rehabilitation exercises but not the clinically relevant activities of transitioning from a chair, negotiating stairs and walking, which are commonly monitored for improvement during therapy for this condition. Therefore, it is unknown if a HAR model trained on data from people who have knee osteoarthritis can be accurate in classifying these three clinically relevant activities. Therefore, we collected inertial measurement unit (IMU) data from 18 participants with knee osteoarthritis and trained convolutional neural network models to identify chair, stairs and walking activities, and phases. The model accuracy was 85% at the first level of classification (activity), 89–97% at the second (direction of movement) and 60–67% at the third level (phase). This study is the first proof-of-concept that an accurate HAR system can be developed using IMU data from people with knee osteoarthritis to classify activities and phases of activities.
Remote Sensing of Dispersed Oil Pollution in the Ocean—The Role of Chlorophyll Concentration
Authors: Haule Kamila , Freda Włodzimierz
Published: May 2021

In the contrary to surface oil slicks, dispersed oil pollution is not yet detected or monitored on regular basis. The possible range of changes of the local optical properties of seawater caused by the occurrence of dispersed oil, as well as the dependencies of changes on various physical and environmental factors, can be estimated using simulation techniques. Two models were combined to examine the influence of oceanic water type on the visibility of dispersed oil: the Monte Carlo radiative transfer model and the Lorenz–Mie model for spherical oil droplets suspended in seawater. Remote sensing reflectance, Rrs, was compared for natural ocean water models representing oligotrophic, mesotrophic and eutrophic environments (characterized by chlorophyll-a concentrations of 0.1, 1 and 10 mg/m3, respectively) and polluted by three different kinds of oils: biodiesel, lubricant oil and crude oil. We found out that dispersed oil usually increases Rrs values for all types of seawater, with the highest effect for the oligotrophic ocean. In the clearest studied waters, the absolute values of Rrs increased 2–6 times after simulated dispersed oil pollution, while Rrs band ratios routinely applied in bio-optical models decreased up to 80%. The color index, CI, was nearly double reduced by dispersed biodiesel BD and lubricant oil CL, but more than doubled by crude oil FL.

Women’s participation in soccer has increased rapidly. The purpose of this study was to evaluate the physiological demands imposed on women’s NCAA Division I soccer players across a season according to speed, total distance traveled, and numbers of sprints measured via GPS (Polar Team Pro®). Eighteen athletes (19.2 ± 1.1 years, 50.5 ± 6.5 mL/kg/min and 23.4 ± 3.6% fat) participated in this study. The analysis was obtained through 13 official matches. Speed zones were defined as Zone 1 (1.0 to 5.99 km·h−1), Zone 2 (6.0 to 10.99 km·h−1), Zone 3 (11.0 to 15.49 km·h−1), Zone 4 (15.5 to 19.9 km·h−1) and Zone 5 (sprint > 20 km·h−1), with Zones 4–5 considered as high intensity running. Individual differences in playing time and total distance were highly variable due to substitutions. Average distance traveled per game in quartiles was 3.9 km, 5.6 km and 7.4 km in the 25th, 50th, and 75th quartiles, respectively. Relative to playing time, players travelled an average of 113.64 ± 17.12 m/min (range: 93.7 to 143.5 m/min) and ran one sprint every 4.12 ± 2.06 min. When distance was summated and analyzed for the entire team, significant difference between halves was found for speed Zones 2, 3 and 4, with greater values found in the first half. Total distance, high intensity running and sprint distance were significantly less than previously recorded in professional players. These findings suggest that coaches should consider the unique physiological demands and recovery opportunities present in NCAA play when constructing practices and conditioning programs.
An Overview of Equine Influenza in South America
Authors: Olguin-Perglione Cecilia , Barrandeguy María Edith
Published: May 2021

Equine influenza virus (EIV) is one of the most important respiratory pathogens of horses as outbreaks of the disease lead to significant economic losses worldwide. In this review, we summarize the information available on equine influenza (EI) in South America. In the region, the major events of EI occurred almost in the same period in the different countries, and the EIV isolated showed high genetic identity at the hemagglutinin gene level. It is highly likely that the continuous movement of horses, some of them subclinically infected, among South American countries, facilitated the spread of the virus. Although EI vaccination is mandatory for mobile or congregates equine populations in the region, EI outbreaks continuously threaten the equine industry. Vaccine breakdown could be related to the fact that many of the commercial vaccines available in the region contain out-of-date EIV strains, and some of them even lack reliable information about immunogenicity and efficacy. This review highlights the importance of disease surveillance and reinforces the need to harmonize quarantine and biosecurity protocols, and encourage vaccine manufacturer companies to carry out quality control procedures and update the EIV strains in their products.

The role of the state in the development of the rocket and space industry
Authors: Murtuzalieva Svetlana Yurievna
Published: May 2021

In the USSR, space exploration was considered a national achievement necessary for the state to raise the patriotic spirit of citizens and show the strength of the country. Of course, then the state was the main investor in this area. During this time, little has changed. As then, and now, all over the world, governments are the main investors in the rocket and space industry. Investments are made through the provision of grants, subsidies and direct fi nancing. Over the past ten years, the number of participating countries implementing space programs and participating in global production chains for the creation of rocket and space products has signifi cantly expanded. In addition, private funding for projects has increased, leading to a signifi cant infl ow of private capital into the space sector. The relevance of this article is explained by the fact that the number of players in the market for rocket and space products has increased signifi cantly, as has the intensity of the race in this area between countries. This trend is also facilitated by the active infl uence on this area of the American company SpaceX, whose achievements are monitored by the whole world, and Roscosmos is trying to keep up with its Western competitor. Also, do not discount China, which is one of the most, if not the most signifi cant, competitors to the United States both in the economy as a whole and in the rocket and space industry. The purpose of this article is to analyze the current situation in the rocket and space industry and the role of government regulation in this area.

Published: May 2021

The article is devoted to an urgent problem of our time — the integration of Canadian energy markets into the energy markets of the Asia-Pacifi c region. Canada’s economy is currently the 16th largest in the world in terms of GDP and is heavily dependent on international trade, whose prosperity is inextricably linked to external markets and the ability to access those markets. In turn, China, Japan, and South Korea are the world’s largest importers of crude oil and liquefi ed natural gas. The purpose of this work is to investigate how exactly interactions between these countries are built on the market, in addition, to explore the building of relationships in a given region. The scientifi c novelty of the work is to consider the relationship between the countries of the Asia-Pacifi c region and Canada, not only based on recently signed agreements but also with the involvement of the opinions and works of modern experts in the fi eld of international energy. The study examines the reasons for the need to enter the energy markets of Canada in the Asia-Pacifi c region, and also analyzes the dependence of the Canadian economy on the economy of the United States of America. Besides, the comprehensive and progressive agreement on the Trans-Pacifi c Partnership — CPTPP, signed in 2018 by Canada and the Indo-Pacifi c countries, was examined. As a result of the study, the need to change the course of Canada’s energy exports towards the Asia-Pacifi c region was substantiated; in addition, the importance of Canada’s energy markets for Asian countries was revealed.

Este artigo propõe uma abordagem histórica sobre imigração a partir da literatura, especificamente das obras Adeus, Haiti, de Edwidge Danticat, e Garota, Traduzida, de Jean Kowok. O principal argumento explora experiências de imigrantes relativas(i) às razões da saída, (ii) às expectativas e frustrações vividas, (iii) aos mecanismos institucionais e informais da acolhida e (iv) à imigração visualizada como sentimentos, particularmente, a formação da família e de outras sociabilidades. A tentativa de problematização desse tema se desdobra da compreensão de que a literatura, inspirada em experiências históricas vividas, como é o presente caso, possibilita a reflexão no campo da História à medida que é também um documento e uma intervenção interessada na realidade. Teoria e método consideraram tais características de modo a interrogar, analisar e explorar Adeus, Haiti e Garota, Traduzida a partir de perspectivas identificadas nas autoras e dos pontos que compuseram o roteiro da pesquisa, anteriormente numerados. Por fim, esperamos que os resultados mais tangíveis animem a inserção da História nas expressivas migrações recentes cuja importância tem sido contada pelos migrantes em narrativas trágicas e dramáticas, mais do que em formatos épicos e exitosos.
Direitas Revolucionárias no Cone Sul
Authors: Souza Mendes Ricardo Antonio

A ideia de revolução alcançou enorme prestígio em boa parte do mundo nos anos 1960 e 1970. As análises acadêmicas do conceito normalmente abordam o termo e o conceito a partir das referências à esquerda que a palavra apresenta. Considerado em grande medida como “esquerdista”, não apenas pelos próprios componentes desse segmento político, mas também pelos setores das direitas, por vezes o termo foi incorporado de forma positiva por parcelas desse segundo grupo em seu discurso. Busco, nesse artigo, apresentar que a utilização do termo “revolução” pelas direitas no Cone Sul não foi desprovida de sentido, assumindo vínculos com a significação associada às esquerdas, mas também apresentando reconfigurações representacionais que devem ser consideradas para uma análise das direitas em relação às suas estratégias e projetos políticos

Risks and Benefits of Kidney Transplantation during the COVID-19 Pandemic: Transplant or Not Transplant?
Authors: Ajaimy Maria , Liriano-Ward Luz , Graham Jay A. , Akalin Enver
Published: May 2021

COVID-19 has significantly affected the transplant community, by leading to decreased transplant activity and increased waiting list time. As expected, COVID-19 causes substantial mortality in both ESKD and kidney transplant populations. This is due to underlying CKD and a high prevalence of comorbid conditions, such as diabetes mellitus, hypertension, and cardiovascular disease in this group. Transplant programs have faced the difficult decision of weighing the risks and benefits of transplantation during the pandemic. On one hand, there is a risk of COVID-19 exposure leading to infection while patients are on maximum immunosuppression. Alternatively, there are risks of delaying transplantation, which will increase waitlist times and may lead to waitlist-associated morbidity and mortality. Cautious and thoughtful selection of both the recipient’s and donor’s post-transplant management has been required during the pandemic, to mitigate the risk of morbidity and mortality associated with COVID-19. In this review article, we aimed to discuss previous publications related to clinical outcomes of COVID-19 disease in kidney transplant recipients, patients with ESKD on dialysis, or on the transplant waiting list, and the precautions transplant centers should take in decision making for recipient and donor selection and immunosuppressive management during the pandemic. Nevertheless, transplantation in this milieu does seem to be the correct decision, with careful patient and donor selection and safeguard protocols for infection prevention. Each center should conduct risk assessment on the basis of the patient’s age and medical comorbidities, waitlist time, degree of sensitization, cold ischemia time, status of vaccination, and severity of pandemic in their region.

Right to live, equity and social justice are watch words that determine quality of life in a society. There is always a fight between the haves and have nots’, in the end the powerful would not only prevail in the society but dominate the have nots’ to the utter dismay of the social thinkers (1). Question arises whether films and film songs address the issue of social inequality and voice against the sufferings of the lowest rung of the people of Tamil Society? In his scholarly article Robert L Hardgrave states that “Film had become increasingly pervasive in almost all aspects of Tamil society and perhaps most prominently in political life”. He also states that “although Bombay is usually considered the capital of the Indian film world, it is within south India that film has made its greatest impact (2).
Embodied Mind and Neural Underpinnings of the Aesthetic Experience. A Case Study from the German Eighteenth Century: 4E Cognition Theories Forecasted by Johann Gottfried Herder
Authors: Gambino Renata , Pulvirenti Grazia
Published: May 2021

Recent theories within the avenue of the bio-cultural turn, and particularly about embodied cognition are forecasted in the anthropological, philosophical, physiological and scientific debate of the late 18th century in Germany. Philosopher and theologian Johann Gottfried Herder contributed to this discourse sigificantly, opening up new perspectives on the link among thought and language and body. In this paper we aim at highlighting some core issues of Herders’s discourse about knowledge, perception and cognition, that seem to anticipate some of the most recent 4E Cognition issues.

Authors: Hasan Mohamad Rais , Mohd Ghazali Mohd Sabri , Mohtar Nor Fazliyana
Published: May 2021

Hydroxyapatite (HAp) with the chemical formula of Ca10(PO4)6(OH)2is a mineral component found in bone structure, and has broad application in many fields. Several sources can be used for the extraction of HAp either synthetic or natural. However, sources such as porcine and bovine have drawbacks that decreased the demand of HAp. This study aimed to extract and determine particle size distribution and pore characteristics of hydroxyapatite nanoparticles (HAp NPs) derived from spotted sardinella (Amblygaster sirm). Further characterization of extracted HAp NPs was carried out by Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS) and Brunauer–Emmett–Teller(BET). SEM analysis has shown that the extracted HApNPs has an irregularsp here-like shape with particle size distribution ranged from 95nm to 100nm.

Published: May 2021

Confirmation of identity, along with determination of the quality and purity of herbal drug is an important step towards ensuring its safety and efficacy. This study therefore sought to document the botanical constituents and drug indications of traditional oral liquid herbal formulations (TOLHFs) manufactured in Ogbomoso, Nigeria. It also examined the conservation status of the medicinal plants so used alongside the cultivation efforts being made by the drug manufacturers in order to provide information on whether continual exploitation of the plants for TOLHFs is sustainable. Through a questionnaire, 14 traditional herbal medical practitioners (THMPs)provided information on the recipes of their products, the sources of their raw material herbs, and types of health conditions treated or managed with the drugs.

Deep The research study focuses on the concept of Fuzzy Logic and its applications in diverse sectors like Behavioural Science, Machining, Business Operations, Medicinal Science, Water Quality Management, Manufacturing, Anti-Braking systems, etc. Fuzzy Logic is regarded as the best option to deal with complex problems which arise due to uncertainty, incomplete information, and lack of preciseness. The major focus of this research is then divided into a case study on the application of Grey Fuzzy Optimization in the Manufacturing and Machining sectors, using the Fuzzy Logic Toolbox of MATLAB. The case study deals with a Job-Shop Scheduling Problem in a Flexible Manufacturing System (FMS). Scheduling of Jobs is a crucial task for meeting and exceeding the market demands. The decision of which part will be the next to be processed considers some criteria that influence the performance of a job shop system. The job shop system is taken from previous literature and the proposed approach is applied to get the optimal scheduling of products. Within the vast field of production and operation, its applicability was tested in scheduling conflicts in flexible manufacturing systems (FMS). All the output values were in the range of single-digit percentage error owing to different sets of rule formations but nonetheless, the proximity of the actual and calculated values reaffirmed the confidence that the verification was justified.

The rolling process had been used in every aspect of our life. Various types of sections like tee, angle, channel, railway track, sheets, foils of different mate-rial are made by rolling process. The quality of the product depends upon the various characteristics of rolling parameters. At the junction, the key role played by lubricants for saving energy and properties of the material in contact. Re-searchers are putting continuous efforts into the tribological analysis and developing new lubricants for the rolling process according to the material. The authors had reviewed the lubricants used in different rolling processes and found out a diverse range of lubricants. Various ecologically safe and effective lubricants had been reviewed. Lubrication performance testing tribometer for testing of tribological properties of lubricants had been reviewed. Hydrodynamic, mixed and boundary lubrication mechanisms had been found in different rolling conditions. The use of lubricants was found helpful in reducing power consumption in rolling and good quality products, hence the cost

Marbofloxacin has promising leishmanicidal activity due to the direct action on the Leishmania chagasi amastigotes. It was developed only for veterinary medicine uses, and it could be used as an drug for the treatment of Canine Visceral Leishmaniasis (CVL). In the present study, we evaluated the leishmanicidal effect and macrophage modulation of marbofloxacin in macrophages infected with amastigotes of L. chagasi. Macrophages were collected from peritoneum of BALB/c mice and infected with promastigotes of L. chagasi. After internalization and transformation into amastigotes forms, cells were treated with marbofloxacin in concentration of 100, 500 and 750 μg/mL for 18 hours. The leishmanicidal effect was evaluated by morphological spects of amastigotes inside of macrophages by phagocytosis assay and detection of death amastigotes and macrophages by TUNEL assay. Macrophage modulation was evaluated by release of cytotoxic metabolites and cytokine production. The results showed that L. chagasi-infected macrophages treated with the highest concentration of the drug showed lower amount of amastigotes into the macrophages (p<0,0632) than untreated infected cells. There was pronounced presence of cellular vacuoles in the treated infected-cells, and more apoptotic amastigotes in alive macrophages. It was observed decreased levels of H2O2, IL-1β, IL-6, and TNF-α dose-dependent of marbofloxacin in infected macrophages. The results indicate the leishmanicidal effect of marbofloxacin in infected macrophages and immunomodulation actions in these cells.

This work presents the manufacturing and characterization process of two types of transparent conductive oxide (TCO) films, as contacts. Aluminum doped zinc oxide (AZO) deposited with the Sputtering technique and tin doped indium oxide (ITO) using the pyrolysis spray technique, these transparent and conductive films were deposited as contacts on a film of siliconrich oxide (SRO) which was deposited by two systems of chemical vapor deposition by low-pressure (LPCVD) and by hotfilament (HFCVD) on quartz substrates with polysilicon film as metal contact, with the object of building two Metal-InsulatingMetal (MIM) structures, one with SRO-LPCVD film and another SRO-HFCVD thus highlighting the electrical characteristics of these structures. The precursors used for the LPCVD system are silane (SiH4) and nitrous oxide (N2O) and for the HFCVD system the gaseous precursors are obtained from a solid quartz source stripped with atomic hydrogen. First, we present results of the optical characterizations of the TCO´s and SRO films, the band gap obtained by Tauc to calculate the size of the nanocrystal in SRO-films, causing light spots. And I-V curves of MIM structures with interesting results.
