Full textAbstract:
There has been a long debate in the literature over whether the caste system is a unique social phenomenon or simply one manifestation of processes of social stratification which have a wider generality. New divisions and differentiations have been giving rise to new antagonism and social norms. Caste is not today what it was before 1950; and it has not become completely class or replica of it in Nepal.

This study aimed to identify the fundamental factors and core values necessary to develop and implement a program for children at local child centers, considering their needs and characteristics. To achieve this, the research questions were set as follows: “What do researchers experience in operating programs at local child centers?” and “What does the experience of operating programs at local child centers mean to researchers?” The research employed the autoethnographic research method, and data were collected through memory materials, cultural artifacts, and self-reflection materials spanning from 2011 to 2022. The collected data were analyzed using the end-point coding method. The research findings revealed four types of programs: “Program of Living as I Am,” “Replica Program of Becoming an Expert,” “Superficial Program of Wanting to Become an Expert,” and “Subtle Program of Becoming an Expert.” These research results are significant as they provide direction and important guidelines for program development and operation. Additionally, they offer insights into the role of operators when utilizing the programs.

Full textAbstract:
Background Despite the global acceptance of the impact factor (IF) by researchers and academic institutions as one, criticism has been voiced regarding its effectiveness in evaluating the unbiased impact of a journal. To overcome the limitations and drawbacks of the IF that were presented by the scientific community, they introduced several other citation-based bibliometric indices. Methods All plastic and reconstructive surgery journals were analyzed, and bibliometric indices were extracted from the relevant source. Pearson correlation coefficients were used to determine correlations between the various indices. Results All correlations in between the various bibliometric indices were found to be positively and statistically significant, ranging from moderately highly associated for the IF and Eigenfactor (r = 0.632) to very strongly associated (r = 0.962) for the IF and the Article Influence Score. Conclusion In the field of plastic and reconstructive surgery, the Eigenfactor and its derivative, the Article Influence Score, could potentially serve as better indices than the IF in demonstrating the overall picture. This information is based on the inclusion of a greater number of journals in the calculation and subtraction of self-citations, without compromising their correlation with other indices. The use of Eigenfactor and other additional bibliometrics cooperatively with the IF could provide the most extensive evaluation of a journal's scientific impact.

Full textAbstract:
Purpose The purpose of this paper is to provide a “Q&A interview” conducted by Joanne Pransky of Industrial Robot Journal as a method to impart the combined technological, business and personal experience of a prominent, robotic industry engineer-turned entrepreneur regarding his pioneering efforts in starting robotic companies and commercializing technological inventions. The paper aims to discuss these issues. Design/methodology/approach The interviewee is Jack Morrison, CEO and Co-Founder, Scythe Robotics. Morrison shares how he and his co-founders started this innovative company, the milestones and challenges he’s faced and his long-term goals. Findings Morrison received Bachelor of Arts degrees in Computer Science and German from Bowdoin College. He attended The George Washington University as a PhD student in Computer Science but left to co-found Replica Labs, a producer of software that turns any mobile phone into a high-quality 3D scanner. Morrison served as Replica’s CTO until it was acquired by Occipital in 2016, where he stayed on as a computer vision engineer until co-founding Scythe Robotics in April 2018. Originality/value While mowing his lawn in Colorado, Jack Morrison had a sudden insight: what if he could apply the latest robotics technology he was so familiar with to the challenge of commercialized landscaping? In 2018, Morrison teamed up with Replica Labs co-founder Isaac Roberts and Occipital’s Davis Foster, to create Scythe Robotics, a company that builds autonomous robotics solutions for the $105bn commercial landscaping industry. In June 2021, Scythe Robotics emerged from stealth with over $18m in funding with its first commercial product: a transformational, all-electric, fully autonomous mower designed to keep crew productivity high while also increasing the quality of cut and worker safety. The machine features eight high dynamic range cameras and a suite of other sensors that enable it to operate safely in dynamic environments by identifying and responding to the presence of humans, animals and other potential obstacles. Simultaneously, the machine captures valuable property and mower performance data, which helps landscape contractors improve workflow, identify upsell opportunities, schedule more efficiently and manage labor costs. The all-electric powertrain is quiet, emissions-free and radically more reliable than gas-powered manual mowers. Scythe Robotics’ business model is based on Robot as a Service. Instead of buying machines outright, customers are billed by acres mowed. This massively reduces contractors’ expenses and eliminates substantial costs. Scythe Robotics is headquartered in Boulder, Colorado and has offices in Vero Beach, FL and Austin, TX. Scythe is the recipient of the 2020 ALCC (Associated Landscape Contractors CO) Innovation Winner and the 2021 Colorado OEDIT Advanced Industries Grantee.

Full textAbstract:
We wanted to know whether the mechanisms that discriminate the motion of first-order patterns (defined by spatial variations of luminance) differ from those that detect the motion of non-Fourier or second-order patterns (defined by spatial variations of contrast). To address this question we tested whether motion discrimination performance of first-order and second-order patterns was affected by a pedestal (Lu and Sperling, 1995 Vision Research35 2697 – 2722). A pedestal is a static replica of a moving pattern. We used pedestals with contrast or modulation depth twice the value at which it becomes possible to discriminate the direction of a moving pattern. A two-interval forced-choice task was used to determine how direction discrimination varies with contrast of sine gratings (1 cycle deg−1) and modulation depth of amplitude-modulated gratings presented either alone or with a pedestal. The amplitude-modulated gratings had a 5 cycles deg−1 carrier modulated at 1 cycle deg−1. Three different temporal frequencies (1, 3, and 12 Hz) were studied. Performance with sine gratings was unaffected by the pedestal at all temporal frequencies tested. For amplitude-modulated gratings the pedestal raised the modulation depth at which it became possible to discriminate the direction of motion. This elevation in threshold decreased when the mean contrast of the pattern was high. This result shows that immunity to pedestals of texture-contrast patterns (Lu and Sperling, 1996 Journal of the Optical Society of America13 2305 – 2318) does not generalise to other non-Fourier motion stimuli.

Dear Readers, It gives me great pleasure to announce the eighth regular issue of 2023. In this issue, five papers by 24 authors from nine countries cover various topical aspects of computer science. In an ongoing effort to further strengthen our journal, I would like to expand the editorial board: If you are a tenured associate professor or above with a strong publication record, you are welcome to apply to join our editorial board. We are also interested in high-quality proposals for special issues on new topics and trends. As always, I would like to thank all the authors for their sound research and the editorial board for their extremely valuable review effort and suggestions for improvements. These contributions, together with the generous support of the consortium members, sustain the quality of our journal. As we want to secure the financial support also for the years to come, we are looking for institutions and libraries to financially support our diamond open access journal as consortium members, who will then benefit from the research community, international visibility, and the opportunity to manage special issues and focused topics within the journal. Please think about the possibility of such financial participation of your institution, we would be very grateful for any kind of support. In this regular issue, I am very pleased to introduce the following 5 accepted articles: In a collaborative research effort between Jordan and Qatar, Ahmad Abusukhon, Ala Al-Fuqaha and Belal Hawashin present their technique for detecting underground water pipeline leakage based on an Internet of Things approach. In another collaboration between researchers from Croatia and Bosnia and Herzegovina, Ani Grubišić, Slavomir Stankov, Branko Žitko, Ines Šarić-Grgić, Angelina Gašpar, Emil Brajković, and Daniel Vasić describe and evaluate the performance of a semiautomatic authoring tool for knowledge extraction in the AC&NL Tutor and discuss strengths and weaknesses. Also in a collaboration between researchers from the United States and United Arab Emirates, Longhao Li, Taieb Znati, and Rami Melhem propose an energy-aware fault-tolerance model for silent error detection and mitigation in heterogeneous extreme-scale computing environments, referred to diffReplication, which is associated with one replica that executes at the same rate as the main process, and one diffReplica that is executed at a fraction of the execution rate of the main process. In a collaboration between researchers form China and Japan, Xiaojuan Liao, Hui Zhang, Miyuki Koshimura, Rong Huang, and Fagen Li propose in their paper an optimized strategy for solving restricted preemptive scheduling on parallel machines applying Partial Maximum Satisfiability (PMS), an optimized version of a Boolean Satisfiability (SAT) solver. Finally, in a collaboration between researchers from South Korea and the USA, Jaeyoung Yang, Sooin Kim, Sangwoo Lee, Won-gyum Kim, Donghoon Kim, and Doosung Hwang aim in their paper to establish a binary classification method for distinguishing copyrighted and noncopyrighted images by introducing a deep hashing model for an image authentication system, which uses deep learning-based perceptual hashing.

Oxborrow, Kathryn. "Inter-Library Loans and Document Supply Services in Italy Appear to Supplement Journal Subscriptions Rather Than Replace Them." Evidence Based Library and Information Practice 6, no. 4 (December 15, 2011): 124. http://dx.doi.org/10.18438/b83614.
Full textAbstract:
Objectives – To examine patterns of Inter-Library Loans and Document Supply (ILL) in a large network of libraries over a period of five years, in order to establish whether ILL services are being used to replace journal subscriptions. The authors also aimed to establish which journal titles were most requested in their network, to inform future acquisitions policy.
Design – Longitudinal study using transactional data collected from the Italian Network for Inter-Library Document Exchange (NILDE) for the period 2005-2009.
Setting – The Italian library sector.
Subjects – Member libraries of NILDE, which is the largest ILL network in Italy with several hundred libraries. These consist primarily of university libraries, but also hospitals and health research institutions, public research institutions, and not-for-profit and public organisations.
Methods – ILL request data collected from the NILDE network software were analyzed. Figures were retrieved for the number of different journal titles requested per year of the study overall and by individual institution. Further analysis was undertaken on requests for more recent articles, those published up to five years prior to being requested. This involved creating a list of the most requested titles for each year, and then compiling a core collection of journals that were requested 20 or more times in each year of the study. These core titles were analyzed for trends by subject and publisher, and for any significant correlations between either Impact Factors (IFs) or citation counts and ILL requests for particular journals.
Main Results – The data revealed that the number of ILLs processed through NILDE increased every year during the period of the study. The majority of journals were only requested a small number of times in the five year period of the study, with 60% being requested five times or less. In the majority of instances, institutions were not borrowing the same title regularly. Analysis of the core collection of journals revealed that these repeated requests of the same title were mainly in the biomedical sciences and science and technology subject areas, and that these journals were often produced by smaller publishers who were not included in consortia purchasing. There was no correlation between journal impact factors (IFs) and ILL requests, but there was a statistically significant correlation between citation counts and ILL requests.
Conclusions – ILL numbers are increasing despite big deals and consortia purchasing. The majority of requests are for articles that are two years old or older, and the authors suggest that this indicates that ILLs do not influence journal subscriptions. The authors suggest that ILLs may have increased during the course of the study (and may continue to do so) due to the current global financial crisis and its impact on library acquisitions.

A review of:
Duy, Joanna and Liwen Vaughan. “Can Electronic Journal Usage Data Replace Citation Data as a Measure of Journal Use? An Empirical Examination.” The Journal of Academic Librarianship 32.5 (Sept. 2006): 512-17.
Abstract
Objective – To identify valid measures of journal usage by comparing citation data with print and electronic journal use data.
Design – Bibliometric study.
Setting – Large academic library in Canada.
Subjects – Instances of use were collected from 11 print journals of the American Chemical Society (ACS), 9 print journals of the Royal Society of Chemistry (RSC), and electronic journals in chemistry and biochemistry from four publishers – ACS, RSC, Elsevier, and Wiley. ACS, Elsevier, and Wiley journals in chemistry-related subject areas were sampled for Journal Impact Factors and citations data from the Institute for Scientific Information (ISI).
Methods – Journal usage data were collected to determine if an association existed between: (1) print and electronic journal use; (2) electronic journal use and citations to journals by authors from the university; and (3) electronic journal use and Journal Impact Factors.
Between June 2000 and September 2003, library staff recorded the re-shelving of bound volumes and loose issues of 20 journal titles published by the ACS and the RSC.
Electronic journal usage data were collected for journals published by ACS, RSC, Elsevier, and Wiley within the ISI-defined chemistry and biochemistry subject area. Data were drawn from the publishers’ Level 1 COUNTER compliant usage statistics. These data equate 1 instance of use with a user viewing an HTML or PDF full text article. The period of data collection varied, but at least 2.5 years of data were collected for each publisher.
Journal Impact Factors were collected for all ISI chemistry-related journals published by ACS, Elsevier, and Wiley for the year 2001. Library Journal Utilization Reports (purchased from ISI) were used to determine the number of times researchers at the university cited journals in the same set of chemistry-related journals over the period 1998 to 2002. The authors call this “local citation data.” (512)
The results from electronic journal use were also analysed for correlation with the total number of citations, as reported in the Journal Citation Reports, for each journal in the sample.
Main results – The study found a significant correlation between the results for print journal and electronic journal usage. A similar finding was reported for correlation between electronic journal usage data and local citation data. No significant association was found between Journal Impact Factors and electronic journal usage data. However, when an analysis was conducted for the total number of citations to the journals (drawn from the Journal Impact Factor calculations in Journal Citation Reports) and electronic journal use, significant correlations were found for all publishers’ journals.
Conclusion – Within the fields of chemistry and biochemistry, electronic journal usage data provided by publishers are an equally valid method of determining journal usage as print journal re-shelving data. The results of the study indicate this association is valid even when print journal subscriptions have ceased. Local citation data (the citations made by researchers at the institution being studied) also provide a valid measure of journal use when compared with electronic journal usage results. Journal Impact Factors should be used with caution when libraries are making journal collection decisions.

Full textAbstract:
AbstractThis chapter draws on a detailed transgenerational case study, the story of ‘Masimbo’, which involves migration, to highlight the conceptualisation and journey of mental illness within an African cultural perspective. In Masimbo’s story, African understandings of mental disorder are side-lined by Western approaches with untoward consequences for him and his family. The implication that is drawn from this, however, is not that African perspectives should replace Western approaches but rather that they should be used together. Thus, Masimbo’s story is illuminated with comments woven in from both an African (Yoruba traditional conceptualisation) and a systemic psychotherapy perspective. This shows how respecting both perspectives is possible and preferable from a person-centred point of view as different narratives/understandings are foregrounded and backgrounded like a tapestry, promoting an approach in which mental illness and the nuances that culture brings, is appreciated and worked with. We conclude with a reflection on the nature of storytelling as mythopoetry within African culture and its role in bridging between perspectives in mental health.

Abstract This chapter tells the story of an experiment published in one of the most prestigious journals in the world. The original experiment found that participants who were shown images of Rodin’s famous sculpture The Thinker reported lower levels of religiosity than those who were shown images of the ancient Greek sculpture of the Discus Thrower. Since it was published in 2012, other teams of scientists have tried to repeat the experiment and failed to replicate the finding: but journals seem reluctant to publish such failures to replicate. This story is a cautionary tale, but also carries hope that scientists can work together to improve one another’s research.

Abstract The Internet offers rapid publication; ‘live’ cross-reference links; and greater inter- action between journals and their readers. Most journals presently replicate some or all of their content onto Web pages and add a search engine; others are using the Internet to improve traditional publishing practices, devising new ways of delivering content with additional features. The peer-review process is revolutionized by unlimited publication space; greater interactivity between editors, authors, and reviewers making peer review an ongoing process of comment and revision (rather than a one-off event); and the possibility of an openness that offers greater accountability and higher standards of ethical behaviour.

In recent years Facebook, MySpace, and other social-networking sites have been blamed for the suicides of teenagers in Missouri, Massachusetts, and New York. Parents complained their children were traumatized by nasty comments posted by cyberbullies on social-networking sites. Schools and districts are taking action in response. According to a T H E Journal survey conducted in 2009, 68 percent of respondents replied that their districts banned social networking sites for students and teachers, 19 respondents replied that they banned social networking sites only for students, and another 12 percent said there was no ban in their districts. In the following case study, which is a true story based on a news report in the Sprint of 2010, a middle school principal calls for parents to yank their children from all social-networking sites after a so-called “Naughty List” was posted on Facebook. Is his extreme measure justifiable?

Full textAbstract:
Aim/Purpose: Labeling a journal as “predatory” can do great damage to the journal and the individuals that have contributed to it. This paper considers whether the predatory classification has outlived its usefulness and what might replace it. Background: With the advent of open access publishing, the term “predatory” has increasingly been used to identify academic journals, conferences, and publishers whose practices are driven by profit or self-interest rather than the advancement of science. Absent clear standards for determining what is predatory and what is not, concerns have been raised about the misuse of the label. Methodology: Mixed methods: A brief review of the literature, some illustrative case studies, and conceptual analysis. Contribution: The paper provides recommendations for reducing the impact of illegitimate journals. Findings: Current predatory classifications are being assigned with little or no systematic research and virtually no accountability. The predatory/not predatory distinction does not accommodate alternative journal missions. Recommendations for Researchers: The distinction between legitimate and illegitimate journals requires consideration of each journal’s mission. To serve as a useful guide, a process akin to that used for accrediting institutions needs to be put in place. Impact on Society: Avoiding unnecessary damage to the careers of researchers starting out. Future Research: Refining the initial classification scheme proposed in the paper.

Full textAbstract:
The article presents the calculation results of dynamic coefficients of hydrodynamic slide bearings obtained using three different methods. The numerical analysis based on a linear and nonlinear algorithm was carried out. The software developed at the Institute of Fluid-Flow Machinery PAN was applied for this purpose. In the experimental research, we used the impulse response method for the determination of dynamic coefficients of hydrodynamic bearings. This method is based on a linear algorithm and allows the calculation of stiffness, damping and mass coefficients for the rotor – bearings system. It allows calculating the complete set of coefficients in only one calculation step. During experimental research, vibrations of the rotor supported on two slide bearings are excited using an impact hammer at the middle part of the shaft. Stiffness, damping and mass coefficients are determined after the analysis of displacements of the journals and the registered excitation forces. The shaft mass is known, therefore mass coefficients can be used for quick verification of the obtained results — by comparing their values with the shaft mass. The experimental tests were carried out on the test rig produced by SpectraQuest. The basic dynamic characteristics of the test rig were determined in the framework of this research, including vibration trajectories of the journals for both bearings — at rotational speeds between 2250 and 6000 rpm. In this speed range, a resonant speed of the rotor was noticed. The vibration trajectories of the journals were used to verify calculated coefficients of the hydrodynamic slide bearings. Since the tested system exhibits nonlinear properties, the three different calculation methods produced large differences in results. The numerical calculations conducted with a linear algorithm provide only one set of stiffness and damping coefficients for each rotational speed (two main and two cross-coupling coefficients for each bearing). In the case of calculations utilizing nonlinear algorithm, the values of coefficients vary over time, notwithstanding the fact that the rotational speed is a fixed value. In each time step, we have different values of stiffness and damping coefficients of the hydrodynamic bearings. In the case of calculations based on the results obtained from experimental research, we receive one set of coefficients for each rotational speed, just as it is for the linear algorithm. The mean and standard deviation of stiffness, damping and mass coefficients are obtained by repeating many times experimental tests followed by statistical calculations. To get values of the coefficients for more than one rotational speed, calculations must be made for each one separately. As a matter of fact, most mechanical systems exhibit certain nonlinear properties. In rotating machinery, we sometimes face distortions of their operation caused by, for example, couplings or supporting structures. In the ideal case, if the system had linear properties and operated correctly without any distortion, the results obtained from all three methods would be the same. The reality is that the experimentally and numerically determined coefficients of the hydrodynamic journal bearings differed, and their differences were discussed in this article. These differences arise from the adopted assumptions and abilities of the three different calculation models. In numerical calculations based on a linear algorithm, it is assumed that the bearing journal is in static equilibrium during its operation. For nonlinear calculations, the solution is found by iterations. The stiffness and damping coefficients are determined for sufficiently small time steps such that we can replace their values in every position of the bearing journal. In experimental research, it is essential that the bearing operation should be considered as the operation in the linear range.

Conventional sintered silicon carbide (SSiC) has been applied in journal bearings of pumps for more than 20 years with the pumped medium itself being the lubricant. High corrosion and wear resistance of SSiC have contributed to this success. The brittle failure of that material quite often is a problem, though, and limits the application of SSiC in highly loaded bearings. In contrast, ceramic matrix composites (CMC) based on C- or SiC-fiber-reinforced SiC-ceramics show strongly improved fracture toughness on the level of cast iron and are applicable in cases where conventional ceramics due to their lack of reliability cannot be used. These CMC-materials have been developed in several programs primarily for space and military applications and are also beeing successfully used in journal bearings for pumps in power plants [1] and for tubular casing pumps [2]. In power plant pumps, low viscosity water of up to 160°C can be the lubricant. In tubular casing pumps quite often water loaded with abrasive sand particles lubricates the bearings. CMC-journal bearings for pumps in cryogenic rocket engines for reusable launch vehicles (RLVs), where the lifetime of mechanical components is a critical issue, are presently tested. Journal bearings of the type introduced in water pumps could replace ball bearings presently in use. Improved stiffness and damping properties, reduced wear, increased reliability and no limitations in speed times diameter would be some of the expected advantages [3]. Journal bearings for hot hinges in re-entry systems are foreseen for the space vehicle CRV (crew rescue vehicle) and have successfully been tested under close to real conditions. They are envisaged to be flight-tested on the experimental NASA vehicle X38. The bearing faces run under dry conditions and temperatures of more than 1600°C in air of about 50 mbar pressure [4]. Presently, only CMCs based on carbon fibers have potential to operate successfully under such conditions.

Torrefaction and biomass pelletization into pellets for solid fuel development are considered sustainable energy solutions to mitigate fossil fuel dependency and environmental challenges. This study investigated the effect of particle size, compaction pressure, and torrefaction on the quality and thermal properties of pelletized corncob residues. The corncob samples were collected, sorted, and pulverized before the torrefaction pretreatment. The torrefaction was achieved by placing the corncob in a furnace at a temperature and residence time of 280 °C and 30 minutes, respectively. The inert atmosphere was attained and maintained by initially purging a nitrogen gas into the torrefying chamber and passing it at 100mL/min during the processes. The raw and torrefied corncob fines were screened to 0.3 mm, 0.5 mm, and 1.0 mm grain sizes. Using starch as a binder (5% wt), pellets were produced employing their respective raw and torrefied fines at compaction pressures of 50 MPa, 75 MPa, and 100 MPa. Though all pellet samples exhibited good quality and thermal properties, the pellets from torrefied corncob are better. Also, the effects of particle size and compaction pressure are significant on the produced pellets. The compressed density varied from 760 to 1,250 kg/m3 and 637 to 920 kg/m3 for raw and torrefied corncob pellets. A maximum heating value of 25.8 MJ/kg was obtained from the torrefied pellet sample of 1.0 mm, rendering improvements of 37.2% when compared with 18.8 MJ/kg of raw corncob of the same particle size. The energy values obtained for torrefied corncob for all particle sizes compared favorably with the value obtained in coal. Investigation of particle size, compaction pressure, and torrefaction on quality and thermal properties of pelletized corncob residue proved that it can replace coal and hence could be used for energy applications.

In SOUTHERN BRAZILIAN JOURNAL OF CHEMISTRY 2021 INTERNATIONAL VIRTUAL CONFERENCE. DR. D. SCIENTIFIC CONSULTING, 2022. http://dx.doi.org/10.48141/sbjchem.21scon.23_abstract_rubensan.pdf.
Full textAbstract:
Dental resins have been designed to replace amalgam restorations due to their more favorable physical, chemical, and biological properties. However, depending on its composition, the efficiency of its polymerization, and the degradation of the polymer matrix, Bisphenol-A can be present and therefore released from this material to the human body. It has been reported that residues of additives and minority by-products of polymer reactions, such as Bisphenol-A, can be released from plastics into aqueous media through polymer hydration, water-polymer diffusion, residue dissolution, and equilibrium between dissolved residues in water and polymer. Over time, this could lead to a polymer material with an external layer practically free of Bisphenol-A. However, the newly formed layer could be removed by brushing during oral cleaning, similar to toothbrushing, exposing the new layer containing Bisphenol-A to the aqueous media. Due to the toxic effects of this compound, an increasing number of plastics labeled as BPA-free have been introduced to the dental market, including tooth coating, dental sealants, and resins. Nevertheless, more specific studies on analytical chemistry have revealed a trace of Bisphenol-A in dental resins labeled as BPA-free and pointed out the need for even more sensitive and accurate detection methods to help manufacturers evaluate the presence of background contaminations in their products and to avoid false-negative results. In this way, liquid chromatography-tandem mass spectrometry has been considered one of the most suitable methods for confirming Bisphenol-A even at low concentrations, in high complex matrices, due to its high select sensitivity. In the present work, we developed a sensitive, reliable, and efficient approach to trace the release profile of Bisphenol-A by LC-MS/MS in dental resin samples purchased in the Brazilian dental market. With the analysis of five different brands of resin composites performed in eight days of exposition to water, four of them released Bisphenol-A from 3.4 pg/mm2 to 10.1 ng/mm2. The brand labeled as BPA-free released BPA at concentrations of 1.1 ng/mm2. However, one sample reached the maximum of released BPA in only 3 days, one in 4 days, and two virtually did not reach a maximum of BPA released into the water in the window time assessed. Limits of detection and quantification of the LC-MS/MS method were 40 pg/mm2 and 100 pg/mm2, respectively, and allowed the quantification of BPA released from a composite labeled as BPA-free. For future analysis, we will conduct a more comprehensive study on the release profile of BPA from resin composites into the water using a tooth brushing simulator to determine if the obtained profiles might have clinical implications.

Abstract The United Nations Guiding Principles on Business and Human Rights (UNGP BHR) provides a clear framework in managing the aspect of human rights for governments and business sectors. While the governments are responsible to protect the human rights, businesses must respect these human rights and ensure an adequate access to remedies for the affected stakeholders. A well-designed grievance mechanism is a pivotal element in promoting accountability and transparency, with all due respect to human rights within the Company. This paper elaborates on the remarkable journey of PETRONAS Upstream in Malaysia, namely PETRONAS Carigali Sdn. Bhd. (PCSB) in building a robust grievance mechanism management for effective and legitimate compliance with host any authority requirements, comprehended by a unique and customized approach that others can replicate.

Full textAbstract:
Universities are under heightened pressure to become more efficient using less resources., the quality of teaching and the student experience must not be sacrificed in pursuit of efficiency. One strategy is to use automation, smart technology to augment the work of human teachers. Not to replace the teacher but to make them better at what they do. Give them smart tools to do their jobs more effectively. Learning Analytics is one such tool that has the potential to leverage teaching capability. This paper examines the learning analytics implementations at five diverse Australian universities (regional and metropolitan) with varying degrees of success reported. These implementations are evaluated using of DeLone and McLean’s (2003) information system success model. It will be seen that participants in this interpretivist case study regard learning analytics as having potential benefits but are not sure about how best to realise analytics systems with extensive usability research built-in and offering sophisticated functionality seem likely to emerge and take precedence over the trial and error approach. This study addresses an apparent gap in the research as limited studies exist targeting both learning analytics and information system success.

Full textAbstract:
Reported in this paper are the field rotor instability and vibration elimination experienced recently on a compressor train installed on an offshore platform for natural gas service. The compressor train consists of a low-pressure compressor and a high-pressure compressor, which is driven by a gas turbine through a gearbox. The compressor train is rated at a maximum continuous speed of 12,054 rpm. During its first commissioning, a high subsynchronous vibration showed up on the high-pressure compressor when it was put on load at full speed. The high-pressure compressor has nine stages, which are arranged back-to-back in two sections. The high-pressure compressor is rated at a discharge pressure of 176.5 bar (2,560 psia). Field vibration data were analyzed and compared to the rotordynamic results from the lateral vibration model of the rotor. The root of the subsynchronous vibration was identified to be the destabilizing aerodynamic excitation generated mainly by the intermediate seal and the impellers. To eliminate the subsynchronous vibration, a gas pocket damper seal was designed specially to replace the existing intermediate labyrinth seal. Meanwhile, the existing tilt-pad bearings were replaced with the deflection pivot bearings to further improve the rotordynamic performance. The compressor was tested with the new center seal and journal bearings at full load, full pressure, and full speed. The subsynchronous vibration was eliminated. Now the compressor train operates smoothly at its design conditions and the vibration readings remain low and stable.

Full textAbstract:
Se presenta la concepción, diseño y puesta en marcha de un hub de innovación para la enseñanza de física experimental usando los sensores de los teléfonos inteligentes (o smartphones). El hub de innovación se fundamenta en el trabajo en red entre profesores y estudiantes universitarios de países iberoamericanos (España, Cuba y Colombia), a partir de procesos y proyectos de cooperación internacional. Así mismo, al interior del nodo de cada país, se busca dinamizar el trabajo en red entre universidades y colegios, a partir del fortalecimiento de la enseñanza de la física al interior de las facultades de ingeniería, así como de la transferencia de conocimiento a escuelas y colegios, a partir de los proyectos de aula desarrollados por estudiantes universitarios, compartidos en entornos escolares. El avance vertiginoso de las Tecnologías de Información y Comunicaciones (TIC) ha traído consigo el desarrollo de los teléfonos móviles hasta llegar a las versiones actuales de los llamados teléfonos inteligentes. La gran variedad de sensores que portan los convierte en dispositivos portátiles muy amenos y atractivos para el desarrollo de innovaciones docentes. Los teléfonos inteligentes pueden ser vistos como laboratorios docentes de Física de bolsillo si pensamos en su portabilidad, conectividad y precisión de sus sensores, cuando estos últimos son utilizados como instrumentos de medición. Los smartphones comenzaron a utilizarse en la docencia desde hace relativamente poco tiempo. Muchos han sido los artículos publicados desde entonces (más de 150) en relación con el uso de sus sensores como instrumentos de medición. La mayoría de estos artículos han sido publicados en revistas emblemáticas de la enseñanza de la física, tales como: European Journal of Physics, American Journal of Physics, Revista Brasileira de Ensino de Física, Physics Education, The Physics Teacher y la Revista Española de Física. Los alumnos utilizan su propio teléfono como instrumento de medición, donde los sensores son controlados mediante aplicaciones gratuitas para móviles. La idea no es exactamente buscar la precisión, más bien se busca que los alumnos puedan interpretar los fenómenos físicos de una forma más clara e inmediata. Las Apps disponibles permiten usualmente visualizar los datos medidos en tiempo real o exportarlos a fichero para su análisis posterior. Se espera que a partir de la puesta en marcha del hub de innovación “Smartphones para Educar: Laboratorios STEM en tus Manos”, se puedan replicar las experiencias en el aula universitaria con estudiantes de las escuelas y colegios, a partir de talleres de apropiación tecnológica presenciales, virtuales y/o híbridos. De igual forma, se visiona que, en el nodo de Colombia, en el mediano plazo, el hub de innovación pueda hacer parte del programa nacional “Computadores para Educar”, donde se pueda ampliar el alcance del proyecto e impactar de una forma más contundente la educación en estados precedentes, con énfasis en la educación campesina y rural, en diferentes regiones del país.
