Cathode Shape Design for Steady-State Electrochemical Machining

The inverse or cathode shape design problem of electrochemical machining (ECM) deals with the computation of the shape of the tool cathode required for producing a workpiece anode of a desired shape. This work applied the complex variable method and the continuous adjoint-based shape optimization method to solve the steady-state cathode shape design problem with anode shapes of different smoothnesses. An exact solution to the cathode shape design problem is proven to exist only in cases when the function describing the anode shape is analytic. The solution’s physical realizability is shown to depend on the aspect ratio of features on the anode surface and the width of the standard equilibrium front gap. In cases where an exact and physically realizable cathode shape exists, the continuous adjoint-based shape optimization method is shown to produce accurate numerical solutions; otherwise, the method produces cathode shapes with singularities. For the latter cases, the work demonstrates how perimeter regularization can be applied to compute smooth approximate cathode shapes suitable for producing workpieces within the range of manufacturing tolerance.

Salinisation effects on freshwater macrophyte growth and establishment in coastal eutrophic agricultural ditches

Abstract The presence of submerged macrophytes is a desired environmental target for coastal freshwater ecosystems. Maintaining a rich community of these species can be challenging as salinisation by sea‐level rise poses an increasing threat to ecosystem integrity. We tested the effect of salinisation on the growth and germination of freshwater macrophytes experimentally using field sediment. In a 56‐day experiment, a macrophyte community was exposed to salinity treatments representing seasonal water management scenarios (a decreasing salinity from 1,500 to 300 mg NaCl/L, a stable salinity of 300 mg NaCl/L, an increasing salinity from 300 to 1,500 mg NaCl/L and a stable salinity of 1,500 mg NaCl/L), crossed with treatments simulating periodic turbidity pulses. All species except Elodea nuttallii grew poorly on the saline and eutrophic sediment, reflecting the challenges of growth in eutrophic coastal systems. Surprisingly, the highest community biomass was achieved in the salinity scenario of 1,500 mg NaCl/L. In a second experiment, field‐collected sediments were incubated at 300 and 1,500 mg NaCl/L salinity (representing summer and winter scenarios), and the germination capacity of the existing seedbank was quantified. Most germinated seedlings did not reach maturity irrespective of salinity treatment. This indicated that sediment salinity, rather than water column salinity, determined seedling establishment success. Interestingly, the established species were characteristic of freshwater habitats, thus indicating maladaptation of the seedbank. Our results show that a mismatch between the high salinity level of eutrophic sediment and the overlaying freshwater may hamper macrophyte growth. Furthermore, target species in coastal eutrophic freshwaters should be evaluated carefully. Elodea nuttalli, which has a wide tolerance range for nutrients and salinity, outperformed other macrophyte species in our study. Thus, species with similar traits may be most successful in establishing macrophyte stands in coastal eutropic wetlands.

Template-directed growth of sustainable carboxymethyl cellulose-based aerogels decorated with ZIF-67 for activation peroxymonosulfate degradation of organic dyes

A novel 3D advanced oxidation catalyst ZIF-67@C-CMC/rGO based on carboxymethyl cellulose (CMC) and reduced graphene oxide (rGO) was successfully synthesized by facile in-situ growth of Zeolitic imidazolate framework-67 (ZIF-67). C-CMC/rGO aerogel crosslinked by poly (methyl vinyl ether-alt-maleic acid)/polyethylene glycol system (PMVEMA/PEG) as the host material was prepared through a template-directed growth model and exhibited outstanding mechanical properties. The sustainable composite was successfully used as an efficient catalyst for activating peroxymonosulfate (PMS) to generate SO4−· and ·OH, then leads to the removal of organic contaminants. As a result, almost 100 % of 10 ppm MB/RhB solution can be degraded within 5 min due to the combination of catalyst aerogel and PMS. What's more, the aerogel showed a wide pH tolerance range from 4 to 9 and maintained up to 93 % of the contaminant removal rate compared to the initial value after four cycles. The ZIF-67@C-CMC/rGO aerogel with high load rate and excellent catalytic degradation performance not only solved the problem of dispersion and recovery of ZIF-67 particles, but also provided a new idea for the compound wastewater purification in sulfate radical-based advanced oxidation processes (SR-AOPs).

Mangrove Ecosystem Services in Mitigation for Mollusca Communities in Lembar Sheet District, West Lombok Regency

Mangroves have an important role in mitigation and a significant contribution to the wealth of macrofauna. The success of mangrove management has significantly affected the diversity of macrofauna which are associated biota. The research objectives were to investigate the composition of mangroves and mollusc communities, the ecological conditions of the waters, and evidence of mangrove ecosystem services in mitigation. The research data sources are faunal, ecological, and social data. The research method uses purposive sampling and data analysis using descriptive statistics. The results showed that 7 mangrove species were found in the Cemare mangrove area. Avicennia marina, Bruguiera gymnorriza, Ceriops tagal, Rhizophora apiculata, Rhizophora mucronata, Rhizophora stylosa, and Sonnetaria alba. The dominant mangroves were Rhizopora stylosa (201 ind/Ha) and Rhizopora apiculata (146 ind/Ha). Meanwhile, the highest abundance of mollusc species was obtained by Cerithidea cingulate (38.94%) and Nerita undata (29.20%) from the gastropod class, while from the Bivalvia class, Anadara grandis (36.07%) and Anadara granosa (19.67%) were found). The condition of the aquatic environment at the research site is still within the tolerance range required for the growth and development of mollusk species. Furthermore, the majority of respondents know or are aware that mangroves have an ecological function (habitat/habitat for animals), an economic function (a livelihood location), a physical mitigation function (abrasion resistance), a non-physical mitigation function (reducing environmental heat) Good category. These results indicate that efforts need to be made to increase mangrove revegetation, given its significant benefits in mitigation.

Sex Differences in Thermal Tolerance of Nine Ornamental Fish Species from the Poecilidae, Cichlidae and Cyprinidae Family

Thermal tolerance and intersexual differences of nine ornamental fish species (Chindango demosoni, Aulonocara stuartgranti, Mylandia lombardoi; Cichlidae; Carassius auratus, Pethia conchonius, Branchydanio rerio; Cyprinidae; Xiphophorus helleri, X. maculatus, Poecilia reticulate; Poecilidae) were determined in this study. CT-min of the species ranged between 9.63 and 11.37 in poecilids, 11.29 and 12.53 in cichlids, 4.67 and 8.46°C in cyprinids, while CT-max ranged between 39.12 and 40.53 in poecilids, 37.82 and 39.37 in cichlids, 36.12 and 40.30°C in cyprinids. While intersexual differences in the CT-min/CT-max values were not evident in cichlids and cyprinids, these values significantly differed across poecilids. The females of poecilids were approximately 0.5 to 1°C more resistant to both low and high temperatures than their males. Among the species included in our study, due to their resistance to low temperature, especially C. auratus and a lesser extent B. rerio and P. conchonius were considered the most suitable ones for outdoor aquaculture in subtropical regions. However, if they are cultured outside of their natural distribution, it should be noted that upon escapement from aquaculture facilities to nature, they may interfere with the ecosystem and compete with native species there due to their wide range of thermal tolerance.

Genomic analysis and biological properties of the novel Serratia liquefaciens phage vB_SlqM_MQ-4.

A novel lytic Serratia liquefaciens phage, named vB_SlqM_MQ-4, was isolated from sewage. BLASTn analysis showed that the genome sequence of phage vB_SlqM_MQ-4 shared only 15% query coverage with that of Escherichia phage vB_EcoM-ep3, with 80.52% identity. Genomic analysis demonstrated that phage vB_SlqM_MQ-4 has a 43,534-bp dsDNA genome with 56% GC content and mightbe a member of a new genus in the order Caudoviricetes. Moreover, vB_SlqM_MQ-4 exhibited strong lytic performance with a short latent period (10 min) and a high burst size (267 PFU per cell) as well as a wide range of thermal (below 70 ℃) and pH tolerance (pH 4-12).

Copper(I)-Mediated Decarboxylative N-Arylation of Dioxazolones: Synthesis of N-Aryl Amides

AbstractDioxazolones, which are potent amide precursors, have been widely explored for the formation of C–N bonds with the help of transition-metal catalysts. Here, we highlight our recent studies on the synthesis of N-aryl amides using dioxazolones and boronic acids in the presence of copper(I) chloride under mild conditions. The versatility of the developed reaction is demonstrated by its wide range of functional-group tolerances as well as the release of nontoxic carbon dioxide. Optimization screenings reveal that a fluorine additive improves the desired reactivity toward the intended transformation. The addition of triphenylphosphine results in an N-acyl iminophosphorane, suggesting the involvement of an N-acyl nitrene intermediate in this transformation.

Analyzing temperature distribution in pyrolysis systems using an atomic model

<abstract> <p>Pyrolysis is a complex energy conversion reaction due to the multiple stages of the process, the interaction of kinetics, mass and heat transfer and thermodynamics. The feedstock, temperature, heating rate, residence time, and reactor design are only a few factors that might impact the final product during the pyrolysis process. This study focuses on the temperature analysis of pyrolysis with sheep manure as feedstock, which includes reactor, pipes and condenser. The examination of the temperature distribution within a pyrolysis system can contribute to the preservation of product quality, the maintenance of heat balance, and the enhancement of energy efficiency. Based on the analysis, the degradation temperature of sheep manure is between 210–500 ℃. Consequently, it is crucial to control the reactor temperature at a desirable temperature that aligns with the degradation temperature of sheep manure. To ensure optimal condensation and maximize bio-oil yield, it is also necessary to control the condenser temperature. This study aims to determine the characteristics of temperature changes in pyrolysis systems using atomic models. The atomic model was built in OpenModelica using the Modelica language. The atomic model was validated with experiment, and it was found that there was a significant difference in reactor temperature. Complex processes occur in the reactor where pyrolysis occurs and various factors can impact the temperature of the reaction. The temperature in the multistage condenser gradually decreases by 1–3 ℃. In the principle of condensation, this temperature drop is considered less than optimal because the cooling fluid in the pyrolysis condensation system is air coolant, which is entirely reliant on ambient temperature. The accuracy of the atomic model is evaluated using error analysis and the mean absolute percentage error (MAPE). A value of 13.6% was calculated using the MAPE. The atomic model can be applied because this value is still within the tolerance range.</p> </abstract>

Uma revisão global sobre traços funcionais de macrófitas invasoras e sua relação com o sucesso no processo de invasão

Abstract: Aim Biological invasions by exotic macrophytes represent one of the main reasons for biodiversity and ecosystem changes in aquatic ecosystems. The reasons for their ability to succeed in new environments have been of ecological interest in the last years. We made a global review, aiming to describe functional traits related with invasiveness of macrophytes. Methods Our search was performed using keywords regarding invasive macrophytes and functional traits. We related the group traits of invasive species with their probability of species invasion success in new localities (invasiveness). We also performed a nestedness analysis that helped us to see which species possessed the higher number of traits related to invasiveness, as well as which traits were more common among the invasive species. Results Traits most often related to invasiveness were those indicating growth (94.5%) and reproduction (90.1%). Nearly 70.4% of invasive macrophytes traits were related with the probability of invasion success. Invasive species had a higher number of morphological and biotic interaction traits related with invasiveness than native species. Our nestedness analysis indicated a low degree of nestedness, but showed us that Egeria densa, Elodea canadensis and Elodea nutalli were the species with a wider range of environmental tolerances, explaining their invasibility across ecosystems. Conclusions We summarized and complement existing reviews on the functional traits related to invasion success of macrophytes. We believe this review contributed to the identification of the most common set of traits related with invasiveness, helping to speculate on successful invaders in the future.

The practicality and utility of this method are demonstrated by the derivatization of the product.

An open label clinical study to evaluate the efficacy of Ayurvedic intervention in chronic spine disorders

The spine is the central supporting structure of the torso; it routes and protects the spinal cord while providing for flexibility and shock absorption. In evaluating Chronic Spine Disorders, it is relevant to understand the prevalence of degenerative Spine pathologies. Spine degeneration affects both the mechanical properties and anatomic morphology of the vertebrae, discs, and surrounding tissues. Such changes progress with time and can affect the range of motion, loading patterns, and tolerance to traumatic events involving loads substantially greater than those applied during common activities. The sequelae of some degenerative pathologies may be misidentified as acute injuries if the underlying process was not previously identified. The COVID- 19 Pandemic & subsequent lockdown restrictions have impacted people’s ability to stay active and mobile. There has been rise in patients with spine-related problems as work from home has led to decrease in activity coupled with an already existing sedentary lifestyle. In the past, a patient suffering from Disc problems may have been prescribed pain killers / medications, instructed to refrain from physical activities, referred for steroidal shots or injections, and when they did not see improvement, they were sent for Spinal Surgery. Frankly speaking only 5% of Spinal problems require Surgeries; the other 95% can be dealt with conservative & curative Ayurvedic Panchkarma Chikitsa.

Synthesis of 1,4-benzoxazine derivatives from α-aminocarbonyls under transition-metal-free conditions

The environmentally friendly and efficient method reported here is highly promising for constructing 1,4-benzoxazine derivatives via C–C/C–O cross coupling cyclization pathways. The present protocol exhibits a wide range of substrate scope and functional-group tolerance.

Differences in Nutrient Uptake Can Influence the Performance of Citrus Rootstocks under Huanglongbing Conditions

Huanglongbing {HLB [Candidatus Liberibacter asiaticus (C Las)]} has been one of the biggest challenges in citrus (Citrus sp.) production in Florida and wherever it is present. HLB-affected trees show significant shoot and root dieback, fruit drop, and reduction in yield. Currently, there is no cure for HLB, and there is no commercial HLB-resistant germplasm. Nonetheless, intensive nutrient management has been promising for citrus growers. The nutrient requirement of HLB-affected trees seems to be greater than that of healthy citrus trees. By understanding the nutrient uptake potential of rootstocks, fertilizer programs can be customized accordingly to enhance the performance of a rootstock in existing groves. Moreover, a reduction in the application of nutrients is possible by planting rootstocks with a high nutrient absorption capacity. Use of rootstocks with good nutrient uptake efficiency can take some burden off the growers who are intensively managing HLB-affected citrus groves. Therefore, the objective of this study was to evaluate and understand the nutrient uptake potential of the citrus rootstocks. To achieve this objective, a 100% hydroponic greenhouse study was conducted with six rootstocks with a range of tolerance to HLB. Several physiological and molecular tools were applied to evaluate the rootstocks for their nutrient uptake potential. A+Volk × O-19 (HLB-tolerant) rootstock had greater nutrient uptake efficiency, whereas US-896 (HLB-susceptible) had lesser nutrient uptake efficiency. Swingle, one of the most popular pre-HLB rootstocks, had poor zinc uptake and the least expression of ZINC TRANSPORTER, suggesting that zinc applications should be emphasized in Swingle plantings. US-896 rootstock expressed the least level of nutrient transporter genes, such as IRON TRANSPORTER. UFR-4 (a good performer under HLB conditions) had a large root biomass, but the uptake efficiency for nutrients was poor, suggesting that the nutrient uptake potential is a complex process that is not solely dependent on root biomass. This study is unique because it is one of the first citrus studies to report nutrient uptake efficiency and the potential of rootstocks. The information presented can be used to improve performance or select better-performing rootstocks under HLB conditions.

ESTIMATION OF THE TOLERANCE AREA FOR CORRECTION PARAMETERS IN INDUCTION ACCELERATION SYSTEMS

The general statements of the problems of the normal functioning of the object in real modes are considered, within which the problems of evaluating the area of admissible parameters are formulated. The issues of formalizing the formulation of problems for calculating tolerances for parameters in the presence of dynamic restrictions with respect to fluctuations of the state vector of a real object are studied. For the purpose of numerical implementation of this kind of inverse problems, the application of practical stability algorithms for systems of differential equations dependent on parameters is proposed. For linear dynamic constraints on the spread of the vector of phase coordinates, a necessary and sufficient condition for the corresponding estimate of the area of deviations of the system parameters in a given structure is given. It is shown that in this concretization the problem of tolerance estimation is completely covered by the statements of stability problems. A class of problems related to the estimation of deviations of the vector of parameters from the calculated ones in the presence of a variation in the quality index is singled out. For the numerical implementation of the formulations of such problems, a linear system of differential equations depending on parameters with fixed initial conditions is studied. The analysis of the corresponding system of differential equations with respect to the spread of the state vector and parameters was carried out by methods of practical stability. Provided that the deviations of the values of the vector of parameters from the nominal are small enough, and the change in the vector of parameters within the tolerance field is linear, the expression for the variation of the quality indicator is presented in the form of a linear form. Within the framework of the formulations formulated, the area of tolerances for parameters is specified structurally in the form of an ellipsoid. The range of admissible parameters was estimated by finding the maximum of the linear form on the ellipsoid. A more complicated variant of the problem of estimating the maximum range of allowable values of the spread of the vector of parameters by the methods of practical directional stability is considered. The algorithms are extended to the case of a nonlinear change in the vector of parameters within the tolerance field and non-fixed initial conditions of the original system. In the applied plan, the considered problem statements are extended to a discrete model of an induction acceleration system for estimating the tolerance range for the correction parameters under given restrictions on the spread of the quality criterion.

Performance Simulation of Multiferroic Neuron Device Driven by an Inclined Monopulse Clock

Multiferroic nanomagnet neuron devices have the advantages of ultra-low power consumption and high integration, which give them promising applications in neuromorphic computing. In this letter, a multiferroic nanomagnet neuron device driven by an inclined monopulse clock is proposed. The strain field direction of the device is at an angle to the nanomagnet's long axis, and the nanomagnet's magnetic moment can be driven to switch randomly 0°/180° by applying a pulse voltage of 0.1 ns pulse width only, thus realizing artificial neuron functions. The numerical model of the neuron device is established based on the Landau–Lifshitz–Gilbert equation. The numerical simulation results indicate that the neuron device can complete high-speed neuromorphic computation with tiny energy use(̴2.65aJ). Additionally, a three-layer artificial neural network based on neuron devices is built. The simulation results demonstrate that the network can recognize handwritten digits in the MNIST dataset at a rate of more than 98% and has a high tolerance for process error. The device has significant advantages over conventional spin neuron devices, including a simple structure, ultra-low energy consumption, fast computation capabilities, and a wide fabrication process error tolerance range. The study results in this letter can offer crucial theoretical recommendations for applying strain magnetoelectronic devices in neuromorphic computing.

Miracle molecule: Salicylic acid

Salicylic acid, a naturally occurring plant hormone acting as an important signaling molecule adds to tolerance against abiotic stresses. It plays a vital role in plant growth, ion uptake and transport. Salicylic acid is also involved in endogenous signaling to trigger plant defense against pathogens. This positive effect of SA could be attributed to an increased CO2 assimilation and photosynthetic rate and increased mineral uptake by the stressed plant under SA treatment. The application of salicylic acid, acetylsalicylic acid or other analogues of SA, to leaves of plants accelerated their leaf area and dry mass production, but plant height and root length remained unaffected. SA reduced the Na uptake of plants and/or increased the uptake of N, P, K, Ca, Mg and the other minerals as compared to control treatment under salt stress. Salicylic acid (SA) plays many roles in plant physiology. Besides pathogenesis-related resistance, SA is involved in the response to abiotic stress. However, the effects of SA on plant resistance to abiotic stress were found contra dictionary, and the actual role of SA in abiotic stress remains unresolved. Generally, deficiency of SA or a very high level of SA increase the plant susceptibility to abiotic stress. The optimal levels for the highest stress tolerance range from 0.1 mm to 0.5 mm for most plants. But the role of SA at a certain level in moderate and severe abiotic stress may be different. This can be attributed to redox regulations in plant cells. In this paper, we discuss the relationship between reactive oxygen species (ROS) and SA, and propose a subsequent intracellular signal transduction network of SA and ROS under abiotic stress. Anti-stress substances besides antioxidant enzymes induced by SA are also summarized.

Local Adaptive Prior-Based Image Restoration Method for Space Diffraction Imaging Systems

Thin-film diffractive optical elements (DOEs) have considerable potential to be used in the field of high-resolution remote sensing imaging satellites because of advantages such as a large aperture, small volume, lightness, wide tolerance range of surface shape, and easy replication. However, there are problems associated with thin-film diffraction imaging, including space variation, serious blur, and low contrast, which result in insufficient imaging quality with regard to traditional optical system requirements. To address this, a local adaptive prior-based image restoration method is proposed for thin-film diffraction imaging systems. An entire degraded image was divided into several isohalo regions based on imaging characteristics. Then, the regularization constraints were adaptively selected and updated according to the local scene prior characteristics. Additionally, the system parameters in the corresponding field of view were used as input to restore each subregion. In particular, the diffraction efficiency (DIE) was introduced into the model to remove the nondesign level background radiation. The experimental results show that the proposed algorithm can effectively improve the image quality of a thin-film diffraction imaging system, including space variation correction, clarity enhancement, and background radiation suppression. Furthermore, a DIE of less than 60% was found to significantly impact the final image products.

A Two-Level Factorial Design for Screening Factors that Influence the Growth of Bacillus sp. Strain ZEID-14 on Acrylamide

Acrylamide is often used to strengthen soil structure and usually leachate from this application forms a major source of acrylamide pollution in the environment. The soil matrix means physicochemical methods of removal will be costly if not difficult. Bioremediation using acrylamide-degrading bacteria is an appealing technique. In this investigation, a previously isolated molybdenum-reducing bacterium with the ability to degrade amides was discovered based on critical characteristics contributing to optimal growth on acrylamide utilizing a two-level factorial design. Five independent parameters that influence the growth of the bacterium on acrylamide were evaluated using a two-level factorial design. Among these variables are pH, temperature, incubation period, acrylamide content, and glucose concentration. The two-factor factorial design was successful in identifying significant contributing parameters to the growth of this bacterium on acrylamide, namely acrylamide concentration, pH, and incubation time, which can be further otpimized using RSM in future studies. Using ANOVA, Pareto's chart, perturbation's plot, and other diagnostic plots, the significant contributing factors or parameters were examined. Half-normal, Cook's distance, residual vs runs, leverage versus runs, Box-Cox, DFFITS, and DFBETAS diagnostic plots all supported the two-level factorial result. This work was conducted using acrylamide concentrations well within the known tolerance range of most acrylamide-degrading bacteria. Incubation time is an expected consequence, as longer incubation time permits more growth. The majority of acrylamide-degrading microorganisms thrive under near-neutral circumstances, as indicated by the results of our investigation, which are consistent with previous literature trends.

Tandem C-C/C-N Bond Formation via Rh(III)-Catalyzed α-Fluoroalkenylation and Sequential Annulation of 2-Arylquinazolinones and gem-Difluorostyrenes.

An efficient method of Rh(III)-catalyzed coupling reaction between 2-arylquinazolinones and gem-difluorostyrenes has been developed. In this work, two diverse structures of monofluoroalkenes and isoindolo[1,2-b]quinazolin-10(12H)-one derivatives were respectively synthesized by controlling the amount of additives (Ca(OH)2 and AgNTf2) to achieve controlled stepwise breaking of the C-F bonds of gem-difluorostyrenes. This reaction has the characteristics of a wide range of substrates and good functional group tolerance. Meanwhile, several control experiments were conducted and a plausible mechanism was proposed.

Ecohydrological, climatic and tree architectural considerations for reforestation program using swamp vegetation of Bangladesh

Swamp forests are now at the edge of extinction in the Haor (Haor ecosystem is a type of wetland comprised of swamp forest located in the lowlands of the north-eastern part of Bangladesh which is characterized by a bowl or saucer shaped shallow depression) region of Bangladesh. To reverse such a trend, there is an urgent need to start a reforestation program. However, the silvics of individual species and dynamics of swamp forest stands are only marginally understood. Hence, the purpose of this study was to provide detailed information on swamp vegetation water tolerance range and to identify suitable habitat range for species that are dominant in the reforestation program. It was found that high water-tolerant species can tolerate waterlogging conditions for an average of 13 weeks, followed by 07 weeks by medium water-tolerant species and 02 weeks by low water-tolerant species. In the case of species water depth tolerance, the high water-tolerant group can tolerate an average of 4ft water followed by 2.5 ft water by medium and 1ft by low water tolerant group. Hijol (Barringtonia acutangula), Koroch (Pongamia pinnata), Pitali (Trewia nudiflora) and Borun (Crataeva magna) were the dominant species used for existing small scale reforestation programs. There are no significant differences in resistance against water flow among Hijol, Koroch, Pitali and Borun regardless of vegetation density and water depth. For future large-scale plantations, the machine learning model shows that more than 50% of Haor area is suitable for plantations by these four species. The information generated through this study can be beneficial to planners and managers to aid in developing plantation plans and the design of habitat restoration and enhancement efforts.
