Influence of Soilless Growing Media Comprising Industrial By-products on Growth of Foliage Plants Epipremnum aureum and Dracaena sp.

Experiments were conducted during August, 2020 to April, 2021 at the ICAR-Directorate of Floricultural Research, Pune, Maharashtra, India to assess the suitability of industrial by-products fly ash and press mud as growing media component for foliage plants Epipremnum aureum and Dracaena sp. Different growing media compositions comprising of fly ash, press mud, cocopeat and vermicompost were evaluated in varying proportions. Foliage plants growth was monitored for nine months duration. Initial pH and electrical conductivity of growing media compositions were determined and leaf samples were analyzed for macro and micronutrients content at the end of the experiment. pH of growing media compositions ranged from near neutral to slightly alkaline pH and electrical conductivity of all media compositions was less than 1.0 dS m-1. Results indicated that growing media composition Fly ash+Vermicompost+Cocopeat (20:30:50) was the most suited growing media to grow Epipremnum aureum under 50% shade condition. Media compositions Cocopeat+Vermiculite+Perlite (33.3:33.3:33.3) and Fly ash+Vermicompost+Cocopeat (20:30:50) were observed to be more suited for growth of Dracaena sp. under 50% shade condition. Maximum plant height, number of leaves, leaf size and petiole length were recorded in Epipremnum aureum and Dracaena sp. plants grown in above media compositions respectively. Results inferred that fly ash along with vermicompost and cocopeat can be used as a growing media component for production of foliage plants Epipremnum aureum and Dracaena sp.

Optimizing the Zn and Mg contents of Al–Zn–Mg wrought alloys for high strength and industrial-scale extrudability

High-strength Al alloys of the 7xxx series are promising candidates for further light-weighting of car bodies. However, they are difficult to process by extrusion: complex geometries in particular pose a major challenge due to high extrusion pressures and tool wear. In addition to process optimization, alloy chemistries can be tailored for properties such as good extrudability or high strength. In this work, several experimental alloys based on EN AW 7108A were investigated with respect to the contents of the main alloying elements Zn and Mg, as well as heat treatment (e.g., homogenization), to achieve good extrudability and favourable mechanical properties. The experimental alloys were initially extruded on a small-scale extrusion press and evaluated with regards to their warm formability, microstructure, extrudability, and mechanical properties in T5 temper. Alloy compositions with Mg contents <1.2 wt.-% are optimal and lead to good extrudability as well as high yield strengths well above 350 MPa. The Zn content, on the other hand, has minor influence on the extrudability, but significantly increases strength at higher contents (∼60 MPa). However, the combined Zn + Mg content should not exceed 7 wt.-%. Based on these findings, two optimized alloys were designed, direct chill cast on industrial scale, and extruded on an industrial extrusion press. The alloys showed good extrudability and high strength in the T5 condition. The results also reveal that the limits of the EN AW 7108A alloy are exhausted and higher strengths could only be achieved with the optimized EN AW 7003 alloy.

Service withdrawal: The uncertain future of the games-as-a-service model

The last decade has seen a rapid growth of service-based offerings – also known as Game-as-a-Service or GaaS – in the video game industry, among which are some of the most popular franchises, such as Fortnite or League of Legends. Yet, even though these games are designed to be played and supported for an indefinite period of time, many studios have recently chosen to curtail services after introducing them, making for unclear outlooks on the future of this business model. Hence, based on secondary sources – including company documents, industry press and dedicated player forums – this multiple case study sets out to investigate the reasons behind studios’ decision to discontinue parts of five popular GaaS. Three main motives for withdrawing services emerge from the cases. Namely, rather than supporting services, studios decide to (1) attend to the company, to (2) attend to players and (3) to attend to the core product itself. The results contribute to the nascent GaaS literature, in particular with respect to business models and product-life cycle considerations. Implications for studios are offered in closing.

Abstract 835: Occupational-related exposure to benzene and risk of female genital cancers: Systematic review and meta-analysis

Abstract Purpose: The IARC monograph has classified benzene as a class I carcinogen, as evidenced by its association with hematological malignancies. However, its association with female genital cancers (ovarian, uterine, cervical) has not been characterized. Therefore, a meta-analysis of cohort studies was performed to determine the possible correlation between occupational benzene exposure and the risk of female genital cancers. Methods: A systematic literature review was conducted that identified 7221 relevant publications. A total of 9 cohort studies detailing occupational exposure to benzene and correlated risk of ovarian, uterine, and cervical cancers were retained, and a meta-analysis (using fixed effects model) was performed. PECOS criteria and STROBE guidelines were followed, and the study protocol was registered in the PROSPERO database (Reg. No. 379720). Study quality was assessed using a modified Newcastle-Ottawa scale (NOS). Results: The summary relative risk (RR) for ever-benzene exposure was 1.22 (95% CI=1.03-1.44, I2&amp;lt;0.001%, n=19); corresponding RR results for female genital cancers incidence and mortality were 1.09 (95% CI=0.92-1.29, I2=5.0%, n=17) and 1.69 (95% CI=1.18-2.4, I2&amp;lt;0.001%, n=9), respectively. These findings were confirmed in sub-analyses by geographical area, industry type, publication year, and levels of benzene exposure. Heterogeneity was detected amongst industries of employment (p-het=0.012) which included petroleum, chemical, printing, and mixed industries categories. Notably, the printing industry (compositors, press operators, and bookbinders) had a summary RR of 2.56 (95% CI=1.45-4.52, I2=35.0%, n=2). However, no heterogeneity was observed for geographical regions (p-het=0.77), duration of benzene exposure (p-het=0.73), publication year (p-het=0.89), or among varying study quality (&amp;lt; or ≥ median NOS score; p-het=0.14). No publication bias was detected (p=0.43). Conclusions: Our meta-analysis identified an association between occupational benzene exposure and the risk of female genital cancers. The association was restricted to the industry of employment. Effects of residual confounding variables cannot be excluded, however, given the present association, there is a potential for causality, especially in workers employed in the printing industry.

Multiple Heat Recovery System for an Industrial Thermal Peeling Press Machine—Experimental Study with Energy and Economic Analyses

The enhancement of energy systems in industrial zones is attracting the attention of researchers from all over the world. At the same time, optimization and advancement in heat recovery systems are now generating major interest in the energy sector. In this context, the present study suggests a new multiple heat recovery system should be applied to an industrial thermal peeling press machine. The new system consists of multiple sources of energy: the heat excess in the chimney, the exhaust gas of the chimney, and the exhaust gas of the boiler. To proceed with testing the potential of the suggested system, a hydraulic thermal peel press machine in the wood industry undergoes different tests to achieve the best configuration that will enable this machine to reach its operational temperature when heating. Five test configurations are proposed, designed, and applied experimentally on this machine. Many parameters were effective during the experimental tests, such as water flow rate, ambient air temperature, and initial water temperature. It was found that the application of the multiple heat recovery system increases the rate of heating from around 7 °C/min to around 13 °C/min. In terms of energy and economy, the “chimney + boiler only” configuration proved to be the best system to apply during the fall and winter seasons.

Understanding the Injury Mechanism in Hamate Hook Fractures by Investigating Fracture Morphologies: A Case Series Study.

Many studies have described hamate hook fractures resulting from direct force from sporting tools. However, several authors have reported fractures that did not occur during swing-related activities. This study aimed to understand the injury mechanism of fractures by investigating their morphologies. We selected patients with hamate hook fractures and collected data on computed tomography scans, injury causes, and how athletes handled sporting tools. We investigated 50 patients, and the study cohort included 32 patients who sustained injuries during sports: 24 during baseball (group A) and 8 during other sports (group B). Sixteen patients sustained injuries from falls (group C), and 2 had their hands crushed while using an industrial press machine (group D). In group A, most patients had a fracture line starting from the middle section of the radial side, accompanied by osteosclerotic changes in their lower hand. In group B, most patients had fracture morphologies similar to those of most patients in group A. The main morphology of fractures in group C was a transverse fracture at the base. Two patients in group D had minimal fragments at the tip of the hooks. Our results question the theory that most hamate hook fractures in athletes are caused by direct force exerted on the palm because the fracture morphology was different from that of patients injured by acute trauma from direct force. Instead, these fractures likely stem from an indirect mechanism involving repetitive force generated by the tendons and muscles acting on the hook.

The mosaic tesserae in the industrial Byzantine wine press, Yavne, Israel: A natural unusually hard chalk or a chemically transformed chalk?

Many of the surfaces of a large industrial scale wine press from the Byzantine period in Yavne, Israel, are covered in mosaic tesserae. These surfaces are part of the grape presses, storage pools, fermentation pools and also the walkways between these structures. The calcitic tesserae resemble limestone in color, texture and fracture properties. We were therefore surprised to discover that they are more disordered at the atomic level than consolidated limestone and in fact they are as disordered as porous and friable chalk. In addition SEM examination of fracture surfaces reveals abundant nannofossils, mostly coccoliths and foraminifera; properties that are also reminiscent of chalk. The nanofossil identifications shows that the tesserae are from the Middle Eocene, and this includes the chalky Maresha Formation that outcrops about 15kms from the site. SEM examination of polished surfaces shows that the larger pores of tesserae are lined with euhedral calcite crystals. Vickers hardness measurements show that the tesserae are much harder than chalk, and are comparable to limestone. There are two scenarios for explaining these seemingly contradictory observations. One scenario is that a chalky limestone geological formation with all these properties exists somewhere in the Mediterranean region and is the source of the raw material for the tesserae. The second scenario is that the Byzantine constructors of the wine press transformed a chalk into a harder and more consolidated material. Chalk transformation processes akin to plaster formation can be excluded based on the analyses of the stable carbon isotopic compositions of the tesserae, as well as their 14C concentrations. A chemical transformation using a weak acid that would only affect the calcite in the vicinity of the accessible pores, and leave the bulk of the chalk and its microfossils in a good state of preservation, is conceivable. In fact a by-product of producing wine is vinegar and the acetic acid of the vinegar could conceivably have been used for this purpose. If indeed a chemical transformation of soft chalk into a hard durable material was used, this would represent a “lost” technology that might even be useful in present times.

Additive Manufacturing of Hot-Forming Dies Using Laser Powder Bed Fusion and Wire Arc Direct Energy Deposition Technologies

Additive technologies are now widely used for the production of complex precise parts and have high potential for the production of forming dies. In this work, hot-forming dies optimized for additive manufacturing were developed and produced with wire arc direct energy deposition (WA-DED) and laser powder bed fusion (L-PBF) technologies. The concept of lightweight hot-forming dies with a 2D-lattice structure was developed, which reduced the weight of each die by 56%, from 14.2 kg to 6.1 kg, in production using L-PBF. Maraging/precipitation-hardened steel 17-4PH was used as an alternative to traditional hot-working steels with slightly lower mechanical properties and a much higher processability in the additive manufacturing process. The workability of the manufactured dies was confirmed by forging tests on an industrial screw press.

Properties of engineered wood flooring with cold-pressing and emulsion polymer isocyanate adhesive

For the sake of improving the product quality and economy, a series of cold-pressing experiments were carried out to investigate the material properties of engineered wood flooring with emulsion polymer isocyanate adhesive. Effect of pressing time, pressure, and adhesive spreading rate on modulus of elasticity (MOE) and modulus of rupture (MOR) was analyzed based on orthogonal experimental design. According to the results, both the MOE and MOR were positively correlated with pressing pressure and adhesive spreading rate. The MOE first increased and then decreased with the increase of pressing time, and MOR showed an increasing trend with the pressing time. Meanwhile, pressing time had the greatest effect on the MOE, followed by adhesive spreading rate, and pressing pressure. However, adhesive spreading rate had the greatest influence on the MOE, followed by pressing time and pressure. Furthermore, pressing time had a significant contribution to both MOE and MOR, and adhesive spread rate had a significant effect on only the MOR. Finally, the optimal cold-pressing condition was determined as 18 s pressing time, 1.25 MPa pressure, and 200 g/m3 adhesive spreading rate, and it is proposed for application in the industrial cold pressing of engineered wood flooring for the highest MOE, MOR, and production benefit.

Collecting and Pre-Processing Data for Industry 4.0 Implementation Using Hydraulic Press

More and more activities are being undertaken to implement the Industry 4.0 concept in industrial practice. One of the biggest challenges is the digitization of existing industrial systems and heavy industry operations, where there is huge potential for optimizing and managing these processes more efficiently, but this requires collecting large amounts of data, understanding, and evaluating it so that we can add value back based on it. This paper focuses on the collection, local pre-processing of data, and its subsequent transfer to the cloud from an industrial hydraulic press to create a comprehensive dataset that forms the basis for further digitization of the operation. The novelty lies mainly in the process of data collection and pre-processing in the framework of edge computing of large amounts of data. In the data pre-processing, data normalization methods are applied, which allow the data to be logically sorted, tagged, and linked, which also allows the data to be efficiently compressed, thus, dynamically creating a complex dataset for later use in the process digitization.

HDR image-based deep learning approach for automatic detection of split defects on sheet metal stamping parts

Sheet metal stamping is widely used for high-volume production. Despite the wide adoption, it can lead to defects in the manufactured components, making their quality unacceptable. Because of the variety of defects that can occur on the final product, human inspectors are frequently employed to detect them. However, they can be unreliable and costly, particularly at speeds that match the stamping rate. In this paper, we propose an automatic inspection framework for the stamping process that is based on computer vision and deep learning techniques. The low cost, remote sensing capability and simple implementation mean that it can be easily deployed in an industrial setting. A particular focus of this research is to account for the harsh lighting conditions and the highly reflective nature of products found in manufacturing environments that affect optical sensing techniques by making it difficult to capture the details of a scene. High dynamic range images can capture details of an environment in harsh lighting conditions, and in the context of this work, can capture highly reflective metals found in sheet metal stamping manufacturing. Building on this imaging technique, we propose a framework including a deep learning model to detect defects in sheet metal stamping parts. To test the framework, sheet metal ‘Nakajima’ samples were pressed with an industrial stamping press. Then optimally exposed, sequence of exposures, tone-mapped and high dynamic range images of the samples were used to train convolutional neural network-based detectors. Analysis of the resulting models showed that high dynamic range image-based models achieved substantially higher accuracy and minimal false-positive predictions.

Optimization of a High Capacity Industrial Bar Press for Jatropha Curcas Oil Extraction

This study allowed us to achieve the optimal yield for the extraction of Jatropha Curcas oil from the main operating variables of an industrial press. We used an industrial bar press with a large extraction capacity to carry out this work. Two interesting and indicative parameters on the influence of the efficiency of the press have been analyzed, namely the number of steps of screw and the no-load temperature on the efficiency, the temperatures of the screw, oil and cake, the flow rate of the press, the power, the specific mechanical energy of the press. The best result of 31.09%, which corresponds to the maximum recovery rate of 76.92%, was obtained with the highest number of steps of screw and the highest no-load temperature. The influence of the no-load temperature of the screw on the stability of the press has also been highlighted. The screw, the oil and the cake temperatures stabilize when the no-load temperature is greater than or equal to 100°C. The study of operating variables shows their role on the specific mechanical energy. Indeed, the increase in the number of steps of screw from 4 to 6 results in a decrease in seed flow and increase in power leading to an increase in the specific mechanical energy from 34.01 to 49.83 Wh/kg.

Informatization of all areas of modern human activity and the rapid development of new information and communication technologies create favorable conditions for the implementation of programs of operational access to remote material and intellectual resources distributed throughout the globe. Over the past decade, social media has changed the way people, communities, and organizations create, share, and consume information from each other and businesses. However, today people have become more careful about their presence on the Internet, especially on social networks. It is becoming increasingly clear that social media poses enormous risks to individuals, communities, companies, and even society as a whole. Examples of such risks in social media include cyberbullying, addictive use, trolling, online witch-hunts, fake news, and privacy violations. The credibility of our study was enhanced by detailed data collection aimed at obtaining a deeper understanding of the phenomena of personal perception of social networks based on primary data obtained from interviews with social network experts and secondary data from the analysis of a large amount of secondary data (industry reports, press releases, eSports columns, and blogs). Using a reverse approach with primary and secondary data, we were able to ensure that all information based on the secondary data set was consistent with the expert interviews, and this was the basis for our interviewee research. As part of this process, we asked our interviewees to describe the motivational factors behind their involvement in social networks. The main goal of this study was based on the multidimensionality and duality of individual perceptions of social networks. Applying a qualitative methodological approach, the article investigates the individual attitude of consumers toward behavior in social networks (SNS). Through the prism of personal brand development, it is understood that people strive to create a satisfactory presentation of the desired self. At the same time, an important criterion of individual behavior in social networks is the preservation of public perception of one's identity. The fear of being unclear is associated with conflicting opinions in front of the target audience. In addition to promotion, the research helps to understand how personal brand interests influence social perception. The obtained results help to gain more knowledge about consumers from the point of view of their involvement in marketing communication.

Today, a sufficiently developed reader chooses a publication that provides informative and expert information according to his interests, tastes, culture and level of education. In recent years, we can see that the demand for industry journalism has increased more than universal journalism. That is why it is one of the most important issues to differentiate mass media in our country and region and consider effective ways to increase the number of readers. The author points out that the market of modern periodicals is filled with newspapers and magazines of different directions, topics, formats, sizes, and regional industry press occupies a special place among this diversity. It is clearly shown that it is the main source of information in the districts and regions, a center of socio-cultural relations, coordinating the life of the local population and forming public opinion. The article examines the originality, formation, development history, functional purpose of the modern regional press, and defines and analyzes the current face of the press in the Syr region. It is shown by examples that the regional press plays a great role in strengthening and improving the independence of the state. Based on the fact that the periodical press is going through a period of complex transformation, the author of the article concludes that in order to effectively implement their activities, regional publications need to stimulate the civil activity of regional readers, in addition to showing the truth and increasing the quality of information products.

Gender bias in AI-based decision-making systems: a systematic literature review

The related literature and industry press suggest that artificial intelligence (AI)-based decision-making systems may be biased towards gender, which in turn impacts individuals and societies. The information system (IS) field has recognised the rich contribution of AI-based outcomes and their effects; however, there is a lack of IS research on the management of gender bias in AI-based decision-making systems and its adverse effects. Hence, the rising concern about gender bias in AI-based decision-making systems is gaining attention. In particular, there is a need for a better understanding of contributing factors and effective approaches to mitigating gender bias in AI-based decision-making systems. Therefore, this study contributes to the existing literature by conducting a Systematic Literature Review (SLR) of the extant literature and presenting a theoretical framework for the management of gender bias in AI-based decision-making systems. The SLR results indicate that the research on gender bias in AI-based decision-making systems is not yet well established, highlighting the great potential for future IS research in this area, as articulated in the paper. Based on this review, we conceptualise gender bias in AI-based decision-making systems as a socio-technical problem and propose a theoretical framework that offers a combination of technological, organisational, and societal approaches as well as four propositions to possibly mitigate the biased effects. Lastly, this paper considers future research on the management of gender bias in AI-based decision-making systems in the organisational context.

REFRAME, REFORM, AND TRANSFORM: POLICY APPROACHES TO IMPROVE NURSING HOME QUALITY IN THE UNITED STATES

Abstract Nursing homes (NHs) are one of the most heavily regulated industries in the United States. However, concerns about quality of care remain, especially for more vulnerable residents, including those with dementia. Concerns only increased during recent natural disasters and the COVID-19 pandemic. Community and industry advocates have suggested diverse reforms that prompted new federal policies. This study poses the following research questions: (1) How do federal policies compare with proposals by community (staff and patient advocates) and industry (NH) advocates to improve quality of care in NHs before and during the pandemic; and (2) How do federal policies address micro, mezzo, and macro level issues? To address these questions, this study employs a multi-level comparison case study design. Primary data includes systematically collected and analyzed federal bills, CMS regulations, and community and industry reports, press releases, and website data from 2018 through 2022. Findings revealed that policy proposals fell into three categories: reframe, reform, and transform. Reframe approaches included minimal transformation at the micro-level. Reform approaches involved more mezzo and macro-level changes. Transform approaches proposed significant structural changes at the macro-level. Community advocates presented far more transformative changes than industry advocates and federal policymakers. Federal policies focused on reframe and reform solutions at the micro level and rarely proposed transforming macro-level structures (e.g., workforce structural inequities). This study has important implications for research, policy, and practice by exposing limitations and strengths of proposed solutions for addressing resident care and concludes with suggestions for better aligning with community advocates.

Procyanidins from Cranberry Press Residues-Extraction Optimization, Purification and Characterization.

Procyanidins are a polyphenolic group that can be found in a variety of foods such as chocolate, tea, cranberries and others. Type A procyanidins can be found in a handful of sources and one of the richest sources are American cranberries. These compounds possess antioxidative, anticancer and anti-inflammatory activities and are most widely used as prevention for urinary tract infections. Cranberries are utilized for jam and juice production, and the latter produces industrial food waste press residues. Press residues contain free and bound procyanidins which can be extracted for use as nutraceuticals. In this study, the extraction of cranberry press residues has been optimized using RSM and the resulting extracts have been purified and fractionated. The obtained procyanidin fractions have been investigated for their antioxidative potential and analyzed using LC-ESI-FTICR-HRMS to determine individual procyanidins. The optimization showed that the optimal extraction can be conducted using acetone in a concentration of 53% without the addition of an acidifying agent. Strong correlation was observed for procyanidin contents and their antioxidative activity using DPPH, ABTS and FRAP methods. The purified fractions contained 78 individual (65 Type A) procyanidins with the degree of polymerization of up to 9.
