Knowing Our True Self and Transforming Suffering toward Peace and Love: Embodying the Wisdom of the Heart Sutra and the Diamond Sutra
Authors: Lin Jing , Khoo Yishin
Published: April 2022

The biggest crisis that we are in nowadays is existential, which is the state of not knowing our true natures or our true selves; hence, we suffer from deep anxiety and we fail to find safety and a way to ground ourselves. In this article, we share our practical experiences of encountering and practicing the teachings of two important Buddhist scriptures: the Heart Sutra and the Diamond Sutra. We show how both sutras, and especially their teachings on emptiness, allow us to remove our attachment to a sense of a separate self, which deepens our understanding about life, and transforms suffering toward peace and love. We further demonstrate the importance of meditation, contemplative chanting and reading, and experimentation with Buddhist teachings as pathways towards understanding our true natures. In sum, both sutras help us to go beyond the materialistic, capitalistic, narrow vision of who we are and to access the higher dimension of our existence, which allows us to discover our cosmic selves in the ultimate reality. It is through experiencing one’s true self that one gains a greater capacity to seek social transformation in times of crisis.

Published: April 2022

The average error rate in liver cirrhosis classification on B-mode ultrasound images using the traditional pattern recognition approach is still too high. In order to improve the liver cirrhosis classification performance, image correction methods and a convolution neural network (CNN) approach are focused on. The impact of image correction methods on region of interest (ROI) images that are input into the CNN for the purpose of classifying liver cirrhosis based on data from B-mode ultrasound images is investigated. In this paper, image correction methods based on tone curves are developed. The experimental results show positive benefits from the image correction methods by improving the image quality of ROI images. By enhancing the image contrast of ROI images, the image quality improves and thus the generalization ability of the CNN also improves.

Authors: Allouche Mohamed , Ishak Sahar , Nasri Ahmed , Harrath Abdel Halim , Alwasel Saleh , Beyrem Hamouda , Pacioglu Octavian , Boufahja Fehmi
Published: April 2022

The toxic effects of two commonly used glucocorticoids, the dexamethasone and prednisolone, on meiobenthic nematodes were assessed in a laboratory experiment for 30 days. Nine treatments were employed, comprised of two single and mixed concentrations of dexamethasone and prednisolone (i.e., 0.14 and 1.4 µg·L−1). The exposure to both glucocorticoids showed significant effects on the abundance and taxonomic diversity of nematodes. Such changes were mainly induced by the decrease in the abundance of the species Microlaimus honestus, considered to be sensitive to prednisolone and by the increase in Enoplolaimus longicaudatus abundance, which can be considered tolerant. The exposure to these glucocorticoids also led to a decrease in 2A feeding groups, 2–4 mm body-size interval, and c-p3 life history type in most treatments, with type of life history and shape of amphids as the most relevant functional traits impacted by these two glucocorticoids. The results could also be explained by the potential antagonism between these two pharmaceuticals.
Impact of Managerial Ownership on Corporate Social Responsibility in Korea
Authors: Cho Jungeun , Ryu Haeyoung
Published: April 2022

A firm’s corporate social responsibility (CSR) record improves its image and that of its managers. This ultimately can positively affect enterprise value. However, CSR investments do not necessarily lead to better firm performance, as long-term costs are incurred. Therefore, managers often make CSR investment choices based on personal incentives. This study analyzed the relationship between managerial ownership and CSR activities in Korean public companies based on different managerial CSR incentives and ownership levels. Using the Korean Economic Justice Institute’s CSR index, the results show that firms with higher managerial ownership had excellent CSR records. Higher managerial ownership led to alignment between managers and shareholders, with managers making CSR investments to enhance long-term enterprise value. However, in firms with lower accounting transparency, managers reduced CSR investments. Managers did not value their CSR reputations in firms with poor financial reporting quality and serious information asymmetry. Instead, they diverted CSR resources to other projects to meet their interests. As Korean firms increase their investment in CSR, CSR disclosure responsibility is strengthened. Our study results provide significant implications to academics, practitioners, investors, and other stakeholders, suggesting the importance of corporate ownership structure on investment in CSR.
LMS/RLS/OCTAVE Vibration Controls of Cold Orbital Forging Machines for Improving Quality of Forged Vehicle Parts
Authors: Chen Mingzhang , Ning Xinfei , Zhou Zijian , Shu Yuwen , Tang Yun , Cao Yang , Shang Xuebing , Han Xinghui
Published: April 2022

Cold orbital forging (COF) as an advanced incremental metal-forming technology has been widely used in processing vehicle parts. During the COF process, the vibration on the COF machine injures the service life of the machine and the quality of the forged part. The study of the vibration control of the COF machine is therefore necessary. In this study, the dynamic model of the COF machine is established, and the vibration performances of some key positions are obtained using Matlab&Simulink software. Subsequently, the vibration performances are effectively verified by conducting a vibration test experiment. Based on the dynamics model of the COF machine and Matlab&Simulink software, least-mean-squares (LMS), recursive least-squares (RLS) and OCTAVE vibration-control algorithms are applied to reduce the vibration. Comparing the vibration performances of the COF machine, these vibration-control algorithms are useful for reducing the vibration of the machine, which improves the service life of the machine and the quality of the forged part. Based on the vibration performances of the COF machine, the effects of LMS and RLS vibration controls are better than the OCTAVE, and they also obviously reduce the vibration of the COF machine. The vibration-control algorithms are first to be applied to reduce the vibration of the COF machines in this study, which will be beneficial to future research on the vibration controls of metal-forming machines and other mechanical systems.

Authors: Alshukri Mohammed , Eidan Adel , Najim Saleh
Published: April 2022

The incorporation of thermal energy storage materials (TESMs) into solar energy systems is a factor that boosts the performance of these systems. In this paper, an experimental study was addressed for enhancing the heat pipe’s thermal performance that works with an Evacuated Solar Tube Collector with Heat Pipe (ETCHP) as a solar water heater system. This is done by adding micro-zinc oxide (ZnO-MP) to the paraffin wax integrated as TESM into the evacuated tube (ET) of the system, where the evaporator section of the heat pipe is completely submerged within the micro-enhanced paraffin wax. Three experimental prototype rigs with one evacuated tube were designed, built, and tested to do the investigation. The most important parameters that have been studied in this study are the thermal resistance and the temperature distribution pattern along the heat pipe. The results show a clear indication of the decrease in the thermal resistance of the heat pipe of the proposed system compared to the system in which pure paraffin wax was incorporated. Also, it was noticed that there is a significant improvement in the temperature distribution along the heat pipe due to the improvement in the conductivity of the micro-enhanced wax compared to the pure wax.

Authors: Abd Alhassan Zainab , Jabbar Murtadha
Published: April 2022

This paper aims to investigate the effect of Ag nanoparticles addition in different percentages (0.12 wt. %, 0.15 wt. %, 0.25 wt. %, 0.35 wt. %) on the microstructure properties of Cu-21%Zn-6%Al shape memory alloy. Optical and SEM were carried out to studied such effects. Two heat treatments were carried out at (825 ℃ and 850 ℃) for 10 min and quenched in ice water. It was observed that both of heat treatment lead to formation M18R martensite with V-shape and needle like, but raising the temperature of heat treatment from 825 ℃ to 850 ℃ lead to a decrease formation α phase, which leads to improving the shape memory properties. Refinement of the grain size resulted as Ag nanoparticles addition increased from 0 to 0.25 wt. %, the grain size decreases from 1551 μm to 212 μm with reduction of 86.32 wt. % at 0.25 wt. % Ag. The microstructure observation indicated that the Ag nanoparticles addition leads to creating a multi-variant oriented martensite microstructure after quenching process in ice water.
Study on the Shear Failure of Reinforced Concrete Beams Using Extended Finite Element Method (XFEM)
Authors: Lateef Hanadi , Laftah Rafil , Jasim Nabeel
Published: April 2022

This research concerns with the fracture behavior of reinforced concrete beams without shear reinforcement numerically. The software ABAQUS is adapted to simulate the crack propagation using the eXtended Finite Element Method (XFEM), taking into account materials nonlinearities using concrete damage plasticity CDP criteria. XFEM is used to solve the discontinuity problems in the simulation. The maximum principal stress failure criterion is selected for damage initiation, and an energy-based damage evolution law based on a model-independent fracture criterion is selected for damage propagation. The traditional nonlinear finite element analysis is used to specify the crack initiation position, which is required to specify the crack location in the analysis of beams using XFEM. Three-dimensional reinforced concrete beam models are investigated subjected to three and four-point loading tests. Simply supported beams under the effect of applied static load are investigated. An elastic perfectly plastic model is used for modeling the longitudinal steel bars. The main variables considered in the study are beam depth and the shear span with beam length. The numerical results are compared with the available experimental results to demonstrate the applicability of the model. The XFEM provides the capability to predict the concrete member fracture behavior.

Authors: Ismaeel Abaas , Abbas Sarmad , Al-Rekabi Wisam
Published: April 2022

This research is an analytical study for simulation both sediment transport and flow within the Tigris river reach located downstream of the Al-Amarah barrage within the Maysan province. This study adopted a three-dimensional program (SSIIM) which use the Navier-Stokes equations for calculating the flow, and the convection-diffusion equations for calculating the sediment transport by the finite volume method as approximated method. A structured non-orthogonal three-dimensional grid is employed to perform the simulation. The obtained results are subsequently compared to the field measurements. The determination coefficient (R2) for this comparison is 0.96 for flow velocity distribution and 0.94 for sediment concentration distribution. The results also showed through the simulation of the water flow, the state of the secondary flow and its effect on both the main flow and the erosion of the river bed in the studied cross sections. According to the high convergence of the results of this model with the field measurements, this model is a powerful tool for simulating flow and sediment concentrations in river systems and channels.

Authors: Mustafa Mohammed , Rishack Qais , Abdulwahid Mohammed
Published: April 2022

This paper demonstrates experimental and numerical studies to investigate in perforation pipes with a phasing 180° and perforation densities 9 spm in a horizontal wellbore. The experimental study was conducted to investigate the phasing angle 180° in a horizontal wellbore. The wellbore has an inner diameter of 44 mm, as well as the length of the pipe is 2 m. For this purpose, a simulation model was created in the wellbore using the ANSYS FLUENT simulation software by using the standard k-𝜖 model and applied to the (CFD) with changing the axial flow from (40 - 160) lit/min and constant inflow through perforations from range (20 - 80) lit/min. Concerning the findings of this study, it was noticed that the total pressure drop (friction, acceleration, mixing) goes high as the total flow rate ratio increases. As well as, an increase of the inflow concerning the main flow rate ratio leads to an increase in the total pressure drop and a decrease in the productivity index. Furthermore, the percentage error of the total pressure drop between the numerical and experimental results in test 4 is about 5.4 %. Also, the average velocity goes high with increasing the total flow rates and the velocity keeps increasing along the length of the pipe until it reaches its maximum value at the end of the pipe due to the effect of the perforations. It was concluded that there are the numerical and experimental results reflected a good agreement concerning the study of the flow-through perforations at 180° angle in terms of pressure drop and apparent friction factor, etc.

Authors: Mohammed Eman , Abood Falah
Published: April 2022

A numerical study of mixed convection inside a horizontal channel with an open square cavity that includes an adiabatic rotating cylinder. The bottom wall of the cavity is heated at a constant temperature, and the remaining walls are adiabatic. The flow is incompressible, laminar and steady state. The equations of continuity, momentum and energy are solved numerically using computational fluid dynamics (CFD) with the commercial software package FLUENT 2019 R1. Reynolds number values of 50, 100 and 150, the Richardson number (0.1 ≤ Ri ≤ 10) and the angular velocity (ω) of cylinder is (0.5 ≤ ω ≤ 4) rad/sec with direction counter clockwise. Prandtl number for air flow is (Pr = 0.7). The results are presented in terms of streamlines, isotherms, and the average Nusselt value is given over the heated bottom cavity. The combined effects of natural and forced convection in and out of the cavity were obtained. The results showed that at low Richardson values, Ri = 0.1 the effect of buoyancy force is neglected. The effect of increasing the cylinder speed is clearly noticeable at low Reynolds values, Re = 50. Average Nusselt values increase with increasing rotational speed of the cylinder for all Richardson values.
Que trouve-t-on dans les bulletins et mémoires de la société centrale de médecine vétérinaire au temps de Louis Pasteur
Authors: Rosolen Serge Georges
Published: April 2022

A l’époque de Louis Pasteur, la Société centrale de médecine vétérinaire (ancêtre de l’Académie vétérinaire de France) édite deux périodiques influents, les Bulletins et les Mémoires de la Société Centrale de Médecine Vétérinaire. L’étude des textes parus entre 1844 et 1893 permet de mettre en évidence les divers sujets qui mobilisent alors les vétérinaires. Durant cette période, la profession vétérinaire se structure et gagne en notoriété. L’ «artiste vétérinaire » devient un savant, dont les compétences en matière d’hygiène et de santé publique sont pleinement reconnues. Les sociétés savantes vétérinaires commencent à publier régulièrement leurs travaux. Un personnage emblématique va dominer ce monde vétérinaire en plein développement : Henri Bouley. Converti aux thèses de Pasteur alors qu’il est Inspecteur Général des Écoles Vétérinaires, il reste pendant quarante ans secrétaire général de la Société centrale de médecine vétérinaire (SCMV) et rédacteur en chef du principal périodique vétérinaire : le Recueil de Médecine Vétérinaire (RMV). Son empreinte va structurer les 23 757 pages des Bulletins et des Mémoires de la SCMV, accessibles en ligne sur Gallica, bibliothèque numérique de la Bibliothèque nationale de France. Nous en avons analysé les contenus : comptes rendus de séances, questions cliniques, débats autour de la profession, sujets imposés ou libres développés dans les

Mémoires. Nous avons présenté sous forme de tableaux synthétiques l’activité de la SCMV et de ses membres au temps de Pasteur, ainsi que l’inventaire chronologique des interactions entre les membres de la SCMV et les membres du comité éditorial du RMV. Des figures rendent compte de l’évolution de la profession vétérinaire au cours de ces cinquante années : enrichissement des savoirs vétérinaires, orientation vers le monde scientifique et médical, contribution de la profession aux travaux de Pasteur et engagement des vétérinaires aux côtés des médecins pour la mise en place d’une véritable politique de santé publique.
Regulation of social media intermediary liability for illegal and harmful content
Authors: Watney Murdoch
Published: April 2022

The discussion focuses primarily on the manner in which the distribution of social media content needs to be governed in ensuring illegal and harmful content is limited (e.g. not accessible to children) whilst ensuring freedom of expression and speech. Closely linked to intermediary liability is the manner in which social media platforms self-regulate harmful content on their platforms. In September 2021 criticism was leveled at Facebook that it was not doing enough to prevent harmful content targeting children. It appears that self-regulation of social media content by companies are not effective. In some instances, it is alleged that profit outweigh safety and security concerns. Zuckerberg, CEO of Facebook, indicated in March 2021 in testimony to the United States Congress that he was of the opinion that social media companies should be regulated. Governments are now in the process of implementing regulations pertaining to social media content. Such regulation will have a ripple effect across the world and other countries will most probably follow. In this regard, the European Commission is considering the implementation of the Digital Services Act.
Since governments are implementing or considering implementing social media regulations, consideration should be given to the following issues: • How and what should a government regulate pertaining to social media content? • The issue of social media intermediary liability for harmful content is contentious. A social media platform cannot escape liability where it is used, for example, for sex trafficking, but how is liability determined? In March 2021 Zuckerberg made the following statement “platforms should be required to demonstrate that they have systems in place for identifying unlawful content and removing it. Platforms should not be held liable if a particular piece of content evades its detection—that would be impractical for platforms with billions of posts per day—but they should be required to have adequate systems in place to address unlawful content.” Zuckerberg submission to the US Congress is tied to the common law standard of duty of care. In the US businesses have a common law duty to take reasonable steps to not cause harm to their customers, as well as to take reasonable steps to prevent harm to their customers.  It is important to establish which human rights’ safeguards government regulation pertaining to content should have in place. Government regulations must provide a safe and secure place for free speech while addressing harmful speech, but the regulations should not silence all speech. Many governments are now concluding that seIf-regulation of harmful content by social media companies are for many reasons not effective. The Internet is borderless and therefore government regulations of social media content must comply with uniform guidelines to ensure free speech protection for the global communication environment
Taxonomy for Higher Education Institutions To Tell Micro-Stories With Content Marketing
Authors: Du Plessis Charmaine
Published: April 2022

The study explored a relatively new area, namely telling micro-stories with content marketing in the context of higher education institutions (HEIs). Although long-form content remains popular, the concept of creating concise content for social media while focusing on what matters to the target audience has gained traction. The study focused on HEIs because they operate in a multifaceted environment where they must maintain a high level of authenticity with current and prospective students. Additionally, many HEIs face increased competition from education service providers operating in various sectors and a reduction in public funding. Although HEIs have embraced digital marketing, effective marketing on social media requires some careful planning. HEIs need to connect and communicate with them emotionally to resonate with the target audience, using micro-stories.

To date, no study has examined which micro-stories HEIs can tell as part of their social media content marketing efforts to capture the attention of their target audience in a cluttered online environment. To take a fresh look at this phenomenon, the social media posts of five HEIs involved in content marketing were analysed and triangulated across four social media networking sites, following a grounded theory approach. The findings indicate that to connect with current and prospective students, HEIs tell micro-stories in an online brand community that are authentic, depicted as a visual experience and meet the long-term needs of the target audience. The proposed taxonomy can stimulate further academic debate and future studies.

With the emergence of mobile dating applications like Tinder, people have changed how they pursue romantic relationships. However, real-world issues pertaining to race and ethnicity that often emerge as people interact are still being experienced in the virtual world. Given the increased popularity of mobile dating applications, there is a pressing need to explore how racialised digital dating are manifested online. The study therefore explored the racialised digital dating experiences of users of the mobile dating application Tinder as well as the influence of Tinder’s affordances on these experiences. Through a qualitative study based on 25 semi-structured interviews, the study identified three categories of racialised digital dating experiences,: Matching Experiences, Communication & Interaction as well as Fetichism & Stereotypes. The study also revealed how Tinder affordances of Locatability, Multimediality, and Visual Dominance could be actualised by users to achieve their preferred racialised digital dating experiences.
Terminology Management for Social Media Communication During Covid 19 Pandemic: A Case Study with a Portuguese Higher Education Institution
Authors: Pinto Susana , Tavares Célia , Silva Manuel
Published: April 2022

The process of attracting new students is a constant challenge for Portuguese Higher Education Institutions (HEIs). It is challenging because it implies the definition of a communication strategy that uses both traditional and digital tactics to promote the institution and its educational offer. Considering the constraints resulting from the COVID-19 pandemic, HEIs had to change their strategies and, in a short period, create digital communication mechanisms to facilitate new students' access to relevant information about the institution.

This paper intends thus to determine and evaluate which are the predominant factors in seeking information about a degree in business sciences, specifically regarding the Porto Accounting and Business School in Portugal. To do that, we will consider the various factors that tend to influence the decision-making process of choosing a higher education degree, namely: the institutional website, social networks (Instagram, Facebook, Twitter and YouTube), other contact mechanisms (live chat, e-mail, text messages, ZOOM videoconference) and alumni testimonials. This study will also consider the role of terminology and positive language to obtain a successful communication strategy for social media.

The analysis of these factors, combined with research developed with a focus group of high school students' graduates to assess their online preferences, will allow the presentation of a digital communication proposal whose purpose is to attract and retain new students. This proposal will consider the role of a strategic terminology management approach to capture students' attention when responding to their social media preferences.

This paper results from the perception that being aware of the students' online preferences and communication skills and needs is essential to enhance the quality of the digital communication that HEIs promote in social media channels, especially in a time frame as specific and multifaceted as the one that we are currently experiencing.
Virtual Communities of Practice for Research Postgraduate Students: Determining Needs and Reducing Isolation
Authors: Barry Jenna , Corcoran Niall
Published: April 2022

Postgraduate research is considered a lonely endeavour with students frequently experiencing social and intellectual isolation. Research offices in many higher education institutions have developed programmes to support supervisors and students undertaking research studies and supervision. These programmes include instruction on research techniques and methodologies but are often lacking in community-based approaches such as creating support and peer groups where students can share information and ideas directly. This study explores the use of online communities of practice as a support tool for postgraduate researchers in a university in Ireland. The research questions seek to determine the antecedents for successful implementation, the dominant problems associated with using online communities, and the motivators for, and barriers to, participation in communities of practice in this context. The study facilitates student collaboration by implementing a community of practice on an enterprise social network (ESN) platform. These platforms are increasingly used in industry to facilitate online community groups that collaborate professionally and socially. Professionally, ESN can be used as a platform to host virtual communities of practice (vCoP), where members can engage in sharing knowledge of their practice domains and experiences. The promotion of ESN and vCoP for this study is a joint initiative of the Research Support Office, the Students' Union, and the Postgraduate Society, who advocate for a strong peer to peer support system for postgraduate students. The study adopts an Action Research design and a mixed-methods approach, and data collection includes system use metrics, surveys, focus groups and interviews. The practical objective of the project is to manage the implementation of the virtual community as a peer-to-peer support environment, and success is determined primarily from usage statistics. This may lead to developing a framework for implementation that is generalisable to other higher education institutions.
Roma Cultural Influencers: Social Media for Identity Formation
Authors: Rétvári Márton Rétvári , Kovács Lajos , Kárpáti Andrea
Published: April 2022

In the ‘Societies and Lifestyles’ project, 2006-2009, 10 post-communist countries analysed values of so-called fringers: small ethnic groups living on the fringes of society. One of them, the Hungarian Roma appeared to have a rich cultural heritage that had been exploited without its integration into an authentic and empowering cultural presence. (Forray & Beck, 2008). Roma heritage, representing about 10 % of Hungarian population, is not exhibited permanently, rarely appear in social media and isn’t recognised even by the socially challenged Roma community. Stakeholder meetings indicate that educational poverty is more threatening for youth than financial needs: it is cultural immersion is needed to build healthy identity. As part of the HORIZON2020 AMASS - Acting on the margins – Arts as social sculpture research project, we developed a training and mentoring program for aspiring Roma cultural influencers. We assumed that social media can be an agent to fight educational poverty and can be used as an arts-based intervention to promote the development of socially challenged youth. Influencers of the Roma community, predominantly male, focus on celebrities and scandals or raise their voice against negative prejudices. Their attitudes do not encourage majority youth to read their messages. Our young Roma girl influencers show cultural values of Roma heritage in witty, youthful voice that is convincing and popular. This paper presents their emergence and shows their unique voices. After two semesters of training in Roma culture, media skills, legal regulations, and online journalism, nineteen girls have successfully established themselves in social media. When disadvantaged minorities try to raise their voices, the response is often characterised as hostile and biased (Glucksman, 2017). We identified psychological traits needed for successful cultural media presence through pre- and post-course measurement. Our training program enhanced skills in all areas with digital competence showing the greatest improvement. The process-folios (documentation of growth during training, cf. Gardner, 1999) showed increased self-assurance and commitment to Roma roots. Those who opted out of the course were threatened by the aggressive tone of social media and / or found regular presence irreconcilable with daily duties (Kárpáti and Somogyi-Rohonczy, 2021). We analysed the social media iconography (Drainville, 2018) of the Roma on Instagram and TikTok in Hungary and on the international scene and identified the scarcity of authentic cultural content. Through cultural immersion, they appropriated ancient motives and symbols that often-assumed new meaning. Not hiding gloomy reality, their intention was to show beauty in their environment and highlight cultural achievements and personal growth against all the odds. The Hungarian Roma Cultural Influencers are not only content providers – they are role models also for their communities.

Background:Vertigo is one of the most distressing symptom seen in patients encountered in clinical practice by otolaryngologist and neurologist. It results from dysfunction of vestibular system, among which most common is BBPV(benign paroxysmal positional vertigo). BPPV present with short episodes of vertigo lasting for few seconds, usually precipitated by change in head position. In BPPV, otoconia from utricles are thought to collect in semicircular canal making them abnormally gravity sensitive. BPPV is clinical diagnosis on the basis of typical history and Dix Hallpike testing. Dr. T Brandt and Daroff introduced Brandt daroff home exercises based on cupulolithiasis theory. In 1980, John M Epley introduced canalolith repositioning procedure of Epley in the treatment of BPPV. Because of lack of consensus regarding the optimal treatment maneuver, in our study we have compared the effectiveness of Brandt Daroff and Epleys maneuver.

Published: April 2022

Social Forestry (SF) is one of the government’s community-based forest management programs, which aims to balance environmental needs with the welfare of communities around the forest. However, in the program’s implementation, due to social norms and gender inequalities, women are often marginalized in access and management of SF. This study analyzes women’s participation in SF, primarily from the perspective and experience of women at the site level. This study used qualitative research; data mining was carried out through focus group discussions (FGD) and interviews with women at the site level and with assistance from civil society organizations (CSOs) in five provinces (Nanggroe Aceh Darussalam, Bengkulu, West Kalimantan, Central Sulawesi, and West Papua). This study shows how cultural barriers affect the forms and good practices of women’s participation in SF and their impacts.

Authors: Jia Xinju , Tan Ran , Peng Biyu
Published: April 2022

In this work, a multi-site polyether amine triazine derivative (ET) was prepared via a one-step process and its structure was confirmed using FT-IR and 1H NMR analyses. Then, the ET was applied to the tanning process and the ET tanning approach optimized and evaluated. The result indicated that after tanning with 8% ET at pH 6 for 6 h, the shrinkage temperature of leather was 83.9°C and the thickness change rate was 97.5%. The XRD, DSC, TG, SEM and Zeta potential analyses demonstrated that ET could couple with the amino groups of the collagen side chains and breaking partial hydrogen bonds between fibers, brought significant improvement to the softness of leather without obvious damage to the high-level structure of collagen. Residual Cl- concentration in the wastewaterdecreased 42.1% in the tanning process compared to the conventional chrome tanning method. The emissions of COD and TDS in the tanning process reduced by 40.5% and 27.2%, respectively. It is conceivable that the ET tanning approach provides an improved approach to promote leather industry to develop sustainably.

Authors: Aslam Masood , Khan Tariq M. , Naqvi Syed Saud , Holmes Geoff
Published: April 2022

As part of industrial quality control in the leather industry, it is important to segment features/defects in wet-blue leather samples. Manual inspection of leather samples is the current norm in industrial settings. To comply with the current industrial standards that advocate large-scale automation, visual inspection based leather processing is imperative. Visual inspection of wet-blue leather features is a challenging problem as the characteristics of these features can take on a variety of shapes and colour variations to constitute various normal and abnormal surface regions. The aim of this work is to automatically segment leather images to detect various features/defects along with the background through visual analysis of the surfaces. To accomplish this, a deep learning-based technique is developed that learns to segment wet-blue leather surface features. On our own curated leather images dataset, the proposed ensemble network performed well, with an F1-Score of 74 percent.

A type of polyurea microspheres with rough surfaces and different sizes (1-12 μm), which was used for waterborne polyurethane matte leather coating, were prepared by precipitation polymerization in H 2 O/acetonitrile system, using isophorone diisocyanate as polymerized monomer, 2,4-diaminobenzenesulfonic acid sodium salt as hydrophilic monomer and nano-SiO 2 as surface roughener. The effect of the loading of isophorone diisocyanate and 2,4-diaminobenzenesulfonic acid sodium salt, the volume ratio of H 2 O/acetonitrile and the addition stage of nano-SiO 2 on the particle size and surface roughness were investigated so as to achieve the excellent matte effect of the coating. The results indicated that the adding of hydrophilic monomer can reduce the particle size of microspheres and improve its re-dispersibility in water, while the increase of the proportion of acetonitrile in the mixed solvent and the loading of polymerized monomer can enlarge the size of the polyurea microspheres. As surface roughener, with the increase of nano-SiO 2 loading, the surface roughness and the particle size of microspheres increase. When nano-SiO 2 is added at the stage of the reaction system getting turbid, the maximum surface roughness of polyurea microspheres can be achieved. Polyurea microspheres with particle size (1-2 μm) and high surface roughness have better matting effect, and the gloss of the prepared waterborne polyurethane coating can be adjusted to less than 1.6° (60°-incident Angle).

Tatanan kehidupan normal baru (New Normal) pandemi covid 19 dapat memanfaatkan teknologi informasi guna mendukung penerapan pyhsical distancing khususnya dalam mengetahui jumlah orang yang sedang berkumpul pada suatu lokasi secara akurat. Selama ini proses untuk mengetahui jumlah orang dii suatu tempat harus dilakukan dengan penghitungan manual yang tentunya membutuhkan banyak upaya dan juga tenaga yang dibutuhkan.Informasi keberadaan orang dalam suatu tempat saat ini sangat dibutuhkan guna melakukan penekanan terhadap COVID-19, oleh karena itu dibutuhkan sebuah aplikasi mobile yang sifatnya dapat digunakan dimana saja dan juga sangat cocok untuk membantu aktivitas-aktivitas yang memiliki mobilitas tinggi. Aplikasi Mobile Assistant yang dibuat ini berbasis Sistem Operasi Android, dengan memasukkan fungsi pelacakan dari lokasi dengan menggunakan GPS (Global Positioning System) atau dengan metode yang biasa disebut Location Based Services (LBS) untuk menginformasikan keberadaan orang dalam suatu tempat umum yang bisa di setting seperti pasar, perkantoran, rumah sakit, tempat peribadatan, kampus, dan lain-lain. Metode Pengembangan Perangkat lunak menggunakan metode Extreme Programming. Ada empat tahapan yang harus dikerjakan yaitu planning (perencanaan), design (perancangan), coding dan testing. Aplikasi ini dapat menunjang kinerja Pemerintah dalam menjalankan New Normal dan mengetahui jumlah  orang dalam kerumunan sehingga physical distancing bisa berjalan secara optimal dan dapat menekan angka laju penyebaran Covid-19.

Air merupakan salah satu sumber kehidupan yang sangat penting. Salah satu cara untuk melakukan penghematan air yaitu dengan memonitoring debit air yang dikonsumsi perbulannya. Pengukuran debit aliran diterapkan pada setiap rumah tangga yang menggunakan PDAM, sehingga setiap rumah dipasang meteran air, yang mana alat tersebut digunakan untuk mengukur atau mencatat seberapa besar volume air yang telah digunakan untuk keperluan setiap rumah tangga. Pengukuran besarnya volume air yang terdapat pada meteran air digunakan untuk penentuan jumlah tarif yang harus dibayar setiap rumah tangga kepada pihak PDAM setiap bulan pemakaian. Pada penelitian ini dibuat sistem yang dapat memonitoring kualitas dan penggunaan air PDAM. Pada sistem ini digunakan sensor turbidity yang akan mengukur tingkat kekeruhan air dalam satuan NTU. Nilai NTU ini akan menunjukkan kualitas air PDAM apakah layak untuk digunakan dalam kebutuhan sehari-hari atau tidak. Sensor water flow akan dipasang ditengah-tengah pipa PDAM, data debit  aliran air yang terukur pada sensor akan  diproses pada modul Arduino Uno untuk dikonversi menjadi data perkiraan biaya pengunaan air PDAM. Selanjutnya semua data akan ditampilkan pada LCD, yaitu data tingkat kekeruhan air, data besarnya debit air dan perkiraan biaya yang harus dibayar oleh pelanggan. Semua data akan dikirimkan ke server blynk  melalui Camera ESP32. Data yang tersimpan pada server dapat diakses menggunakan aplikasi blynk pada smartphone. Selain itu data juga akan tersimpan pada SD Card sebagai back up data. Hasil pembacaan sensor turbidity menunjukkan nilai kekeruhan air sebesar 5 NTU. Nilai eror dari hasil pembacaan sensor water flow sebesar 1,6% yang artinya tingkat akurasinya sebesar 98,4%. Sedangkan data hasil pembacaan sistem penghitung biaya penggunaan air PDAM tidak terdapat eror sehingga akurasi datanya mencapai 100%.

Produk sampah setiap hari semakin meningkat seiring dengan bertambahnya jumlah produk dan pola konsumsi masyarakat. Banyak masyarakat yang tidak memisahkan sampah organik dan anorganik saat pembuangan. Salah satu penyebabnya adalah masyarakat tidak dapat membedakan sampah organik dan anorganik. Berdasarkan permasalahan tersebut maka dirancang sebuah alat berbasis Internet of Things yang menggunakan NodeMCU ESP8266 sebagai mikrokontroler-nya. Untuk membedakan sampah organik dan anorganik digunakan tiga sensor sekaligus, yakni sensor proximity infrared, Kapasitif dan Induktif. Data yang dibaca oleh alat ini kemudian menyalakan LED sesuai jenis tempat sampah. Pada penelitian ini, juga dirancang tempat sampah yang menggunakan sensor ultrasonic untuk mendeteksi ketinggian sampah. Informasi ketinggian ini kemudian dikirimkan ke aplikasi monitoring berbasis website menggunakan jaringan wifi dan protokol MQTT. Aplikasi ini digunakan oleh petugas kebersihan untuk memantau tempat sampah mana saja yang sudah harus diangkut. Dari hasil pengujian, ketiga sensor proximity yang digunakan berhasil membedakan sampah organik dan anorganik. Jarak yang direkomendasikan agar sensor bekerja optimal adalah 3 mm. Data yang didapatkan oleh alat pemilah juga berhasil dikirimkan ke aplikasi monitoring ketinggian sampah. Petugas mendapatkan notifikasi pada website, tempat sampah mana saja yang sudah harus diangkut.

Esophageal stenosis is a morphofunctional alteration that causes inflammatory lesion in the submucosal and muscular layers of the esophagus, inducing them to fibrosis and altering the esophageal diameter. The present report addresses the use of a balloon dilator as an auxiliary way to correct esophageal stenosis in a canine, female, Pug patient, with a history of recurrent vomiting as the main complaint. Through endoscopy, it was observed that the thoracic esophagus was inflamed, with thickened and fibrotic mucosa, in addition to whitish colored fibrous rings, which hindered the passage of the probe, enabling the determination of the diagnosis of esophageal stenosis. In this report, we opted for the use of a dilator balloon, with three procedures being performed one week apart, to improve the symptomatic condition. After the dilator procedure, the favorable development of the clinical condition presented by the patient was possible.
