Authors: Prambudi Widyatmoko Reza , Giyanti Ida
Published: June 2021

This study aims to propose a lean analysis framework for waste management and to test it into the field case. The proposed framework was applied in a weaving process of a textile company in Indonesia. The seven classical Lean wastes were identified using value stream mapping (VSM). The result was then analyzed using the waste assessment model within which waste relationship matrix (WRM) and waste assessment questionnaire (WAQ) according to the answers of the head of weaving division studied. The major source of wastes was then determined utilizing the value stream analysis tool (VALSAT). In order to thoroughly examine the root cause of such dominant wastes and to propose corrective plans to minimize the waste, a fishbone diagram was used. As the main result, this study provides a lean waste analysis framework with examples to orientate managers about wastes. Particularly in our specific case, the results demonstrate that the waiting and defect become the most significant wastes that need to be treated. These findings allow a company to organize its activities and select tools or practices to optimize its efforts to create proper corrective plans in eliminating waste. In our study, the plans include periodic maintenance of weaving machines, clear division of tasks on the distribution of weft yarns, and eliminating unnecessary activities. In addition, it is mandatory to ensure the quality of warp yarns delivered to the weaving process as well as to perform a periodic calibration of equipment on weaving machines. This study advances in the theoretical and practical field by showing a structured way to incorporate lean analysis that can be adopted for any organization.

Approximate Models for the Lattice Thermal Conductivity of Alloy Thermoelectrics
Authors: Skelton Jonathan
Published: June 2021

Thermoelectric generators (TEGs) convert waste heat to electricity and are a leading contender for improving energy efficiency at a range of scales. Ideal TE materials show a large Seebeck effect, high electrical conductivity, and low thermal conductivity. Alloying is a widely-used approach to engineering the heat transport in TEs, but despite many successes the underlying mechanisms are poorly understood. In previous work, first-principles modelling has successfully been used to study the thermodynamics of alloy formation and to investigate its effect on the electronic structure and phonon spectrum. However, it has so far only been possible to examine qualitatively the impact of alloying on the lattice thermal conductivity. In this work, we develop and test two new approaches to addressing this. The constant relaxation-time approximation (CRTA) assumes the primary effect of alloying is on the phonon group velocities, and allows the thermal conductivity to be calculated assuming a suitable constant lifetime. Alternatively, setting the three-phonon interaction strengths to a constant further enables an assessment of how changes to the phonon frequency spectrum influence the lifetimes. We test both approaches for the Pnma Sn(S1-xSex) alloy system and are able to account for the substantially-reduced thermal conductivity measured in experiments.
EHreact: Extended Hasse Diagrams for the Extraction and Scoring of Enzymatic Reaction Templates

Published: June 2021

Data-driven computer-aided synthesis planning utilizing organic or biocatalyzed reactions from large databases has gained increasing interest in the last decade, sparking the development of numerous tools to extract, apply and score general reaction templates. The generation of reaction rules for enzymatic reactions is especially challenging, since substrate promiscuity varies between enzymes, causing the optimal levels of rule specificity and optimal number of included atoms to differ between enzymes. This complicates an automated extraction from databases and has promoted the creation of manually curated reaction rule sets. Here we present EHreact, a purely data-driven open-source software tool to extract and score reaction rules from sets of reactions known to be catalyzed by an enzyme at appropriate levels of specificity without expert knowledge. EHreact extracts and groups reaction rules into tree-like structures, Hasse diagrams, based on common substructures in the imaginary transition structures. Each diagram can be utilized to output a single or a set of reaction rules, as well as calculate the probability of a new substrate to be processed by the given enzyme by inferring information about the reactive site of the enzyme from the known reactions and their grouping in the template tree. EHreact heuristically predicts the activity of a given enzyme on a new substrate, outperforming current approaches in accuracy and functionality.

Published: June 2021

The dispersion of particulate porous solids in size-excluded liquids has emerged as a method to create Type III porous liquids, mostly using insoluble microporous materials such as metal-organic frameworks (MOFs) and zeolites. Here, we present the first examples of Type III porous liquids based on porous organic cages (POCs). By exploiting the solution processability of the POCs, racemic and quasiracemic cage microparticles were formed by chiral recognition. Dispersion of these porous microparticles in a range of size-excluded liquids, including oils and ionic liquids, formed stable POC-based Type III porous liquids. The flexible pairing between the solid POC particles and a carrier liquid allows the formation of a range of compositions, pore sizes, and other physicochemical properties to suit different applications and operating conditions. For example, we show that it is possible to produce porous liquids with relatively low viscosities (7-14 mpa∙s) or high thermal stability (325 °C). A 12.5 wt. % Type III porous liquid comprising racemic POC microparticles and an ionic liquid, [BPy][NTf2], shows a CO2 working capacity (104.30 μmol/gL) that is significantly higher than the neat ionic liquid (37.27 μmol/gL) between 25 °C and 100 °C. This liquid is colloidally stable and can be recycled at least 10 times without loss of CO2 capacity.

Cyanine dyes are exceptionally useful probes for a range of fluorescence-based applications. We recently demonstrated that appending a ring system to the pentamethine cyanine ring system improves the quantum yield and extends the fluorescence lifetime. Here, we report an optimized synthesis of persulfonated variants that enable efficient labeling of nucleic acids and proteins. We demonstrate that a bifunctional sulfonated tertiary amide significantly improves the optical properties of the resulting bioconjugates. These new conformationally restricted cyanines are compared to parent species in a range of contexts including their use on a DNA-nano-antenna, in single-molecule Förster resonance energy transfer (FRET) applications, far-red fluorescence lifetime imaging microscopy (FLIM), and single-molecule localization microscopy. These efforts define contexts in which eliminating cyanine isomerization provides meaningful benefits to imaging performance.
Machine Learning to Predict Diels-Alder Reaction Barriers from the Reactant State Electron Density
Authors: Vargas Santiago , Hennefarth Matthew , Liu Zhihao , Alexandrova Anastassia N.
Published: June 2021

Reaction barriers are key to our understanding of chemical reactivity and catalysis. Certain reactions are so seminal in chemistry, that countless variants, with or without catalysts, have been studied and their barriers have been computed or measured experimentally. This wealth of data represents a perfect opportunity to leverage machine learning models, which could quickly predict barriers without explicit calculations or measurement. Here, we show that the topological descriptors of the quantum mechanical charge density in the reactant state constitute a set that is both rigorous and continuous, and can be used effectively for prediction of reaction barrier energies to a high degree of accuracy. We demonstrate this on the Diels-Alder reaction, highly important in biology and medicinal chemistry, and as such, studied extensively. This reaction exhibits a range of barriers as large as 270 kJ/mol. While we trained our single-objective supervised (labeled) regression algorithms on simpler Diels-Alder reactions in solution, they predict reaction barriers also in significantly more complicated contexts, such a Diels-Alder reaction catalyzed by an artificial enzyme and its evolved variants, in agreement with experimental changes in kcat. We expect this tool to apply broadly to a variety of reactions in solution or in the presence of a catalyst, for screening and circumventing heavily involved computations or experiments.

Published: June 2021

COVID-19 government regulations resulted in increased social isolation, risk of stress, depression, anxiety, cognitive decline, and re-hospitalization. Telehealth has been highlighted as a potential bridge for healthcare needs, especially in the COVID-19 context. In response to this need our group developed a multicultural, intergenerational, community-based psychosocial intervention. We trained more than 300 volunteers who were able to provide friendly phone support in more than 17 languages to more than 600 older adults across the Greater Montreal Area who could benefit from social connection and support to access community resources. The experience has been heartwarming and facilitating enriching life experiences for seniors, volunteers, and clinicians alike. Furthermore, some preliminary observations suggest that this intervention might have positive effects on the seniors’ mental health.

Aim/Purpose: The aim of this study is to explore the role of service-learning in Information Systems (IS) education.

Background: While the use of modern technologies presents many operational benefits, such as the lowering of the costs, it may also aggravate social-economic is-sues. IS professionals should account for these issues as well as exhibit the skills demanded by modern-day employers. Hence, why there is a need for IS educators to adopt a new pedagogy that supports the development of more holistic and socially responsible IS graduates.

Methodology: In this qualitative exploratory case study, two IS service-learning courses at a South African university were studied. Interviews, course evaluations, and reflection essays were analyzed to gain insight into the implications that service-learning may have for students.

Contribution: This study contributes to IS education research by advancing discussions on the role of service-learning in providing learning outcomes such as the development of important skills in IS, civic-mindedness, and active participation in society.

Findings: The findings showed that the courses had different implications for students developing skills that are important in IS and becoming civic-minded due to the variation in their design and implementation.

Recommendations for Practitioners: It is recommended that IS educators present their courses in the form of service-learning with a careful selection of readings, projects, and reflection activities.

Recommendations for Researchers: IS education researchers are advised to conduct longitudinal studies to gain more insight into the long-term implications that service-learning may have for IS students.

Impact on Society: This paper provides insight into how IS students may gain social agency and a better understanding of their role in society.

Future Research: It is recommended that future research focus on mediating factors and the implications that service-learning may have for IS students in the long-term.

Study of nickel leaching using sulfuric acid and phosphoric acid on the selectivity of low-grade laterite nickel ore under atmospheric conditions has been successfully carried out. In this study, the laterite nickel leaching process was carried out by varying the solution concentration and operating time. The concentrations of sulfuric acid and phosphoric acid solutions were varied at 5 M and 6 M concentrations, while the operating time was varied at 4 hours and 6 hours. For other operating conditions, it is kept constant with an operating temperature of 90 Ã¢âÆ, pulp density 15% w / v, particle size Ã¢â°Â¤ 200 mesh. After that, the analysis stage was carried out using an atomic absorption spectroscopy (AAS) tool to determine the nickel content in the sample. The results showed that the highest nickel recovery was obtained at the concentration of 5 M sulfuric acid solution of 2.60% and 5 M phosphoric acid of 2.59% with the optimum operating time at 4 hours of operating time.
Ion transporters and their molecular regulation mechanism in plants
Authors: Walid Saibi , Faiçal Brini
Published: June 2021

With the global population predicted to grow by at least 25% by 2050, the need for sustainable production of nutritious foods is important for human and environmental health. Recent progress demonstrate that membrane transporters can be used to improve yields of staple crops, increase nutrient content and resistance to key stresses, including salinity, which in turn could expand available arable land. Exposure to salt stress affects plant water relations and creates ionic stress in the form of the cellular accumulation of Na+ and Cl- ions. However, salt stress also impacts heavily on the homeostasis of other ions such as Ca2+, K+, and NO3- and therefore requires insights into how transport and compartmentation of these nutrients are altered during salinity stress. Since Na+ interferes with K+ homeostasis, maintaining a balanced cytosolic Na+/K+ ratio has become a key salinity tolerance mechanism. Achieving this homeostatic balance requires the activity of Na+ and K+ transporters and/or channels. The aim of this review is to seek answers to this question by examining the role of major ions transporters and channels in ions uptake, translocation and intracellular homeostasis in plants.
