AbstractIndia’s coal contribution to the total electricity generation mix stood at 73% in 2018. To meet India’s NDC ambitions, the federal government announced determined targets to integrate 450 GW Renewable Energy in the grid by 2030. This paper explores the pathways to integrate high RE generation by 2030 with effective balancing of supply and demand and associated challenges of flexibility requirements. A Unit commitment and economic dispatch model, which simulates the power system operation was used. The overall share of variable renewables reaches 26% and 32% in the Baseline Capacity Scenario (BCS) and High Renewable Energy Scenario (HRES) respectively. Improved ramp rates and a minimum thermal loading limit induce flexibility in the thermal fleet. In the HRES, more than 16 GW of coal plants are required for two-shift operations in April and more than 50% of days see an aggregate all-India ramp from the coal fleet in excess of 500 MW per minute. Battery Storage provides daily balancing while reducing VRE curtailment to less than 0.2% in the HRES. Nationally Coordinated dispatch shows increased power transfer from high VRE regions to export power during high VRE generation periods. It is thus found that high RE penetration is possible by 2030 at no extra system costs.

„Die ungeklärten Gefahrenpotentiale der Gentechnologie“. Öffentliche Wissenschaft, Inszenierungsstrategien und Rhetorik der Objektivität im Kontext der bundesdeutschen Gentechnologie-Debatte
Authors: Schmidt Anna Maria 
Published: November 2022

ZusammenfassungIm März 1986 veranstalteten verschiedene ‚ökologiebewegte‘ Institutionen in Heidelberg ein öffentliches Fachsymposion mit dem Titel „Die ungeklärten Gefahrenpotentiale der Gentechnologie“, auf dem internationale Wissenschaftler*innen unterschiedlichster Disziplinen referierten. Anhand dieses Fachsymposions zeigt der Artikel, wie sich das öffentliche Auftreten von Wissenschaftler*innen als eine Form von politischem Aktivismus lesen lässt. Anhand dieser Perspektive wird herausgearbeitet, wie Biolog*innen, Chemiker*innen, Mediziner*innen, Rechts- und Politikwissenschaftler*innen politische Botschaften zu platzieren suchten, indem sie sich gerade als unabhängige Wissenschaftler*innen in Szene setzten. Das Heidelberger Fachsymposion, so die vertretene These, war darum beides: ein Ort der Wissenschaftsvermittlung und der politischen Agitation, und das in einer Zeit, da die schwarz-gelbe Bundesregierung an einer Gentechnikgesetzgebung arbeitete und auf unabhängige Expertisen angewiesen war. Der Beitrag macht deutlich, wie der Rekurs auf wissenschaftliche Unabhängigkeit zu einer Strategie in der kontroversen Debatte um den Einsatz von Gentechnik wurde. Er nimmt dabei eine Dimension politisch-wissenschaftlicher Aktivität in den Blick, die das in der Wissenschaftsgeschichte etablierte Expert*innen-Konzept nicht berücksichtigt.
Material gradients in gastropod radulae and their biomechanical significance: a combined approach on the paludomid Lavigeria grandis

Published: November 2022

Abstract
The radula, a chitinous membrane spiked with teeth, is the molluscan autapomorphy for the gathering and processing of food. The teeth, as actual interfaces between the organism and the ingesta, act as load transmitting regions and have to withstand high stresses during foraging — without structural failure or high degrees of wear. Mechanisms contributing to this were studied previously in paludomid gastropods from Lake Tanganyika. For some species, gradients in hardness and Young’s modulus along the teeth were detected, enabling the bending and relying of teeth onto the next row, distributing the stresses more equally. The here presented study on one of them — Lavigeria grandis — aims at shedding light on the origin of these functional gradients. The mechanical properties were identified by nanoindentation technique and compared to the elemental composition, determined by elemental dispersive X-ray spectroscopy (EDX, EDS). This was done for the complete radular (mature and immature tooth rows), resulting in overall 236 EDX and 700 nanoindentation measurements. Even though teeth showed regional differences in elemental composition, we could not correlate the mechanical gradients with the elemental proportions. By applying confocal laser scanning microscopy (CLSM), we were finally able to relate the mechanical properties with the degree of tanning. CLSM is a common technique used on arthropod cuticle, but was never applied on radular teeth before. In general, we found that nanoindentation and CLSM techniques complement one another, as for example, CLSM is capable of revealing heterogeneities in material or micro-gradients, which leads to a better understanding of the functionalities of biological materials and structures.
Organizational Culture as a Determinant of Outcome in Teams: Implications for the Pediatric Cardiac Specialist

Published: November 2022

AbstractAlthough enormous effort has focussed on how to build an effective culture in the business community, relatively little effort has addressed how to achieve this in the hospital environment, specifically related to the field of congenital heart disease teams. The examination of culture in pediatric cardiac care is particularly important for several key reasons: first, it represents high-stakes medicine, second, there are multiple stakeholders requiring collaboration between cardiologists, surgeons, anaesthesiologists, perfusionists, nursing staff, and allied health care professionals, and finally, both the patient and the family are intimately involved in the care pathway. This review article investigates some of the critical components to building an effective culture, drawing upon similarities in other disciplines, thereby fostering high performance multidisciplinary teams in congenital cardiology care. Strategies to change culture such as Kotter’s model of change are also discussed. High performance teams share one common vital characteristic: psychological safety for team members to speak their minds, thereby fostering an open culture, in which creativity can flourish to facilitate major breakthroughs. Adoption of the “Flight Plan” review promotes patient centric care and champions a psychologically safe culture.
Influence of warming climate and the green revolution on the optimum range of weather parameters of longan yield in Taiwan since 1909
Authors: Lai Li-Wei 
Published: November 2022

Abstract
Longans are the fruits of a subtropical evergreen tree (Dimocarpus longan Lour.) and are widely distributed in Southern China and Southeast Asia. However, there is a lack of historical records of these fruits. In addition to air temperature, other factors, such as the green revolution effect (GRE), sunshine duration, flower bud differentiation, flowering, and production period, may also be important for longan yield. This study incorporated Duncan’s multiple range tests, linear regression models, and multi-regression models, using the forward stepwise method. The results showed that a warming climate was unfavourable to the longan fruits yield (LFY), as the mean negative impact of climate change on LFY was 2489.6 ± 1072.2 kg/ha (mean difference ± 95% CI) under GRE. When considering warming climate and GRE, the results showed that, at the time of flower bud differentiation, the optimum ranges of mean air temperature and relative humidity (RH) were 18.0–19.4 °C and 73.9–75.7%, respectively; during flowering, the optimum ranges of cloud cover, sunshine-hour, and rainy days were 6.8–7.3 oktas, 381.3–476.6 h, and 28.9–41.9 days, respectively; during the production period, the optimum ranges of mean diurnal temperature and RH were 6.8–7.4 °C and 75.1–79.4% respectively. A smaller optimum range of weather parameters aids in a greater slope of the accumulated frequency of the LFY. The GRE and small optimum ranges of weather (stable weather conditions) were found to assist in ensuring stable LFY.

Published: November 2022

AbstractWe study thetruthful facility assignmentproblem, where a set of agents with private most-preferred points on a metric space have to be assigned to facilities that lie on the metric space, under capacity constraints on the facilities. The goal is to produce such an assignment that minimizes the social cost, i.e., the total distance between the most-preferred points of the agents and their corresponding facilities in the assignment, under the constraint of truthfulness, which ensures that agents do not misreport their most-preferred points. We propose aresource augmentation framework, where a truthful mechanism is evaluated by its worst-case performance on an instance with enhanced facility capacities against the optimal mechanism on the same instance with the original capacities. We study a well-known mechanism, Serial Dictatorship, and provide an exact analysis of its performance. Among other results, we prove that Serial Dictatorship has approximation ratio$$g/(g-2)$$g/(g-2)when the capacities are multiplied by any integer$$g \ge 3$$g≥3. Our results suggest that with a limited augmentation of the resources we can achieve exponential improvements on the performance of the mechanism and in particular, the approximation ratio goes to 1 as the augmentation factor becomes large. We complement our results with bounds on the approximation ratio of Random Serial Dictatorship, the randomized version of Serial Dictatorship, when there is no resource augmentation.
Arctic charr phenotypic responses to abrupt generational scale temperature change: an insight into how cold-water fish could respond to extreme climatic events
Authors: Hooker Oliver E. , Adams Colin E. , Chavarie Louise 
Published: November 2022

AbstractPhenotypic plasticity, the ability of an organism to express multiple phenotypes in response to the prevailing environmental conditions without genetic change, may result in a response to anthropogenic environmental change. Given that increasing climate variability is predicted to pose a greater risk than directional climate change, we tested the effect of a water temperature differential of 4 °C on the Arctic charr phenotypic within a single generation. We demonstrate that Arctic charr phenotype can respond rapidly and markedly to an environmental temperature cue. The plastic response to different temperature regimes comprised a shift in the mean expressed phenotype but also coupled with a reduction in the between-individual phenotypic variation in the expressed head shape. The magnitude of shape difference between temperature conditions was cumulative over time but the rate of divergence diminished as fish became larger. Overall, individuals raised in the elevated temperature treatment expressed a phenotype analogous to a benthivorous ecotype of this species, rather than that of the parental pelagic feeding form. The response of cold-water freshwater species to temperature change is likely to be an interaction between the capacity of the organism for phenotypic plasticity, the mean speed of change in the environment, and the degree of short interval variation in the environment.
Valorization of Waste Wood Flour and Rice Husk in Poly(Lactic Acid)-Based Hybrid Biocomposites

Published: November 2022

AbstractThis study explores the possibility of developing a new class of hybrid particulate-filled biocomposites using wood flour and rice husk wastes as environmentally friendly additives to poly(lactic acid) (PLA) as matrix material. Samples were prepared with fillers of different concentrations (0, 2.5, 5, 7.5 and 10 wt %), while the ratio of wood flour and rice husk was fixed at 1:1 in all cases. The preparation of biocomposites was performed through extrusion using a twin-screw extruder. Subsequently, they were formed into specimens by injection molding. Mechanical, thermal, thermomechanical, and morphological properties were examined. The addition of natural waste particles resulted in a remarkable improvement both in tensile and flexural modulus; however at a cost of impact strength and tensile strength. Meanwhile, flexural stress at conventional strain values were barely affected by the presence of wood flour and rice husk. The SEM images confirmed that there is a limited interfacial adhesion between the components, which supports the results obtained during mechanical tests. Both the differential scanning calorimetry (DSC) and the dynamic mechanical analysis indicated that the glass transition temperature of PLA was not affected by the incorporation of filler particles; however, the crystalline structure was gradually altered with increasing filler loading according to the DSC. Additionally, the particles were observed acting as nucleating agents, thereby increasing the overall crystallinity of PLA.
A closest point method library for PDEs on surfaces with parallel domain decomposition solvers and preconditioners
Authors: May Ian C. T. , Haynes Ronald D. , Ruuth Steven J. 
Published: November 2022

AbstractThe DD-CPM software library provides a set of tools for the discretization and solution of problems arising from the closest point method (CPM) for partial differential equations on surfaces. The solvers are built on top of the well-known PETSc framework, and are supplemented by custom domain decomposition (DD) preconditioners specific to the CPM. These solvers are fully compatible with distributed memory parallelism through MPI. This library is particularly well suited to the solution of elliptic and parabolic equations, including many reaction-diffusion equations. The software is detailed herein, and a number of sample problems and benchmarks are demonstrated. Finally, the parallel scalability is measured.

Published: November 2022

AbstractUsing a case-study approach, we aim to understand how teachers interact with both analogue and digital resources in the science classroom for formative assessment (FA) purposes and their justifications for such interactions. The study was conducted in the context of a European Union project on FA in science and mathematics education. The case involved two Norwegian primary school teachers teaching their grades 5 and 7 students a series of science lessons on the topic “how to prevent microorganisms from spreading.” The data set consisted of lesson plans, classroom observations, pre- and post-interviews conducted with teachers, student tasks, post-interviews with students, and student work. We identified eight analogue and digital resources, which were used to employ five FA strategies. The strategies that were most commonly used related to “engineering effective classroom discussions” that elicited evidence of student understanding and “activating students” as autonomous learners and peer instructors. The teachers’ rationales for using the selected resources were mainly connected to their effectiveness, practicality, and relevance. Teacher interactions with the selected resources are described, and educational implications are discussed.

AbstractThe activity of penta- FTPhPFe(III)/Al2O3 biomimetic catalyst in the reaction of methane direct conversion into methanol by green oxidant hydrogen peroxide was studied at T = 150–350 °C and atmospheric pressure, where methanol yield was 19.2% with methane conversion of 28%. Based on the results of the structural analysis of the Al2O3 support and the biomimetic catalyst sample the mesoporosity of support with pore size in the range of dp = 2.4–22.2 nm in the cylindric shape with an open end and the synthesized biomimetic nanostructure were determined. The data on the definition of the nature and quantitative assessment of Al2O3 support acid–base centers are given that made possible to describe probable mechanism of methane coherent-synchronized oxidation into methanol on the biomimetic.

Published: November 2022

AbstractPredictive maintenance has revealed as one of the paradigms of Industry 4.0. This paper addresses a complete system for the acquisition, computing, monitoring and communication of ventilation equipment in underground tunnels based on TCP/IP protocol and accessible via WEB services. Not only does the proposed system collect different sensor data (temperatures, vibrations, pressures, tilt angles or rotational speed), it performs local data processing as well. This feature is the newest and most important of all those provided by the system design, and there is no equipment that offers a similar performance in current ventilation systems. This paper shows the design and implementation of the equipment (system architecture and processing), as well as the experimental results obtained.

AbstractIn the first two years of the COVID-19 pandemic, members of Boston Emergency Medical Services, the City of Boston’s municipal ambulance service, had 7,689 encounters with confirmed-positive Boston residents. As COVID-19 virus strains continue to infect residents in Boston and across the country, understanding the correlation between population positivity, EMS encounters, and hospitalizations can inform healthcare response. This study examines urban virus-surveillance indicators that can serve as an early warning of the volume of Emergency Medical Services (EMS) encounters with COVID-19 positive patients and subsequently how EMS encounters with confirmed COVID-19 patients can serve as an early indicator of future hospital-demand surges. With daily data from Boston EMS and three other public agencies, we evaluate the relationship between five indicators and confirmed Boston EMS COVID-19 encounters by estimating separate Auto Regressive Integrated Moving Average models and cross-correlating their residuals. This study finds a significant and positive correlation between new COVID-19 cases citywide and EMS encounters 6 days later (p < 0.01), as well as between confirmed EMS encounters with COVID-19 patients and the number of intensive care unit beds occupied 7- and 18 -days later (p < 0.01). This study provides city health leadership needed clarity on the specific ordering and associated time lag in which infections in the population increase, EMS members encounter positive patients, and hospitals deliver care.

Published: November 2022

AbstractPsychosocial factors contribute to persistence of poverty, but are rarely addressed in poverty reduction programs. We use mixed methods to investigate the relationship between a psychosocial behaviour change approach—empowered worldview (EWV), and investment decisions in children wellbeing among smallholder farmers in Zambia. Three years after exposure to EWV, logistic regression model results suggest that exposure to EWV was associated with an increased probability of parents providing basic needs of children including school fees, clothes, and food. This probability increased with more trainings. Using a matched sample, the average treatment effect on the treated of EWV is positive and statistically significant. Qualitative results reveal EWV enhanced participant agency, spouses’ propensity to work together and with others in the community, and aspirations for themselves and their children. These results point to the prevalence of psychosocial constraints and the need for interventions to sustainably address them to support human development.
Best of ASCO 2022—bladder cancer
Authors: Pichler Martin 
Published: November 2022

SummaryAlthough no game-changing studies in bladder cancer were presented this year at ASCO, we saw a series of interesting data including follow-up updates, exploratory analyses and promising results of phase I/II trials. An up-date analysis of the JAVELIN 100 Bladder study indicated a benefit of avelumab maintenance treatment irrespective of the response to platin-based first-line treatment and administration of second-line treatment. A new HER2-directed antibody drug conjugate, disitamab vedotin, showed promising results with high-response rates in HER2 high and low bladder cancer. Longer follow-up data confirmed the significant benefit of enfortumab-vedotin in the third-line treatment setting.
