Effect of Calcination Temperature on the Adsorption Performance of Tanggamus Natural Zeolite for Ammonium Removal from Shrimp Pond Wastewater

This research explores the potential of locally sourced natural zeolite from the Tanggamus District, Indonesia, for the removal of ammonium from shrimp pond wastewater. The study utilizes a comprehensive approach involving desilication modification, batch adsorption experiments, and field-scale application. The zeolite, predominantly composed of clinoptilolite, undergoes calcination at varying temperatures, with 200°C proving to be optimal for enhancing ammonium adsorption capacity. The study also highlights the efficient use of zeolite at a lower dosage of 5 g/L, yielding high removal efficiency. The real-world effectiveness of this method was confirmed by field experiments, where the application of calcined zeolite resulted in lower ammonium concentrations in shrimp ponds. The results demonstrate that the application method, specifically direct spreading in the ponds, affects adsorption performance. These findings underscore the potential of using Tanggamus Natural Zeolite as a cost-effective and eco-friendly solution for ammonium control in shrimp pond wastewater. This work paves the way for future research focusing on the long-term application effects and zeolite regeneration methods to further improve the economic and environmental efficiency of this approach.

Structural and enzymatic characterization of a novel metallo-serine keratinase KerJY-23

KerJY-23 was a novel keratinase from feather-degrading Ectobacillus sp. JY-23, but its enzymatic characterization and structure are still unclear. In this study, the KerJY-23 was obtained by heterologous expression in Escherichia coli BL21(DE3), and enzymatic properties indicated that KerJY-23 was optimal at 60 °C and pH 9.0 and could be promoted by divalent metal ions or reducing agents. Furthermore, KerJY-23 had a broad substrate specificity towards casein, soluble keratin, and expanded feather powder, but its in vitro degradation against chicken feathers required an additional reducing agent. Homology modeling indicated that KerJY-23 contained a highly conserved zinc-binding HELTH motif and a His-Asp-Ser catalytic triad that belonged to the typical characteristics of M4-family metallo-keratinase and serine-keratinase, respectively. Molecular docking revealed that KerJY-23 achieved a reinforced binding on feather keratin via abundant hydrogen bonding interactions. This work not only deepened understanding of the novel and interesting metallo-serine keratinase KerJY-23, but also provided a theoretical basis for realizing the efficient use of waste feather keratin.

ELSSIE: A compact stereo spectral imager for planetary surface morphology and composition

Here we describe the design, prototyping, testing, and simulations that were conducted to demonstrate the technology for a concept of the next generation landed planetary spectral imager, the Europa Lander Stereo Spectral Imaging Experiment (ELSSIE). The concept was developed originally for a Europa Lander mission, but the design is applicable, with simplifications, to any ocean world of the outer solar system or to non-icy bodies, including Enceladus, the Moon, Mars, or the surface of Ceres. ELSSIE's design consists of two subassemblies. A Sensor melds a high-resolution, 20-filter, 0.4–3.65 μm, adjustable-focus multispectral stereo imager with a 0.8–3.6 μm point spectrometer, sharing a radiation-shielded single Teledyne H2RG 2048 × 2048 pixel focal plane array (FPA). Each camera includes two 6-position filter wheels with 5 filters and a blank position, providing 10 bandpasses for each of the 2 stereo eyes, and uses 700 × 700 pixels of the FPA. The point spectrometer uses a 6 ×350 pixel strip of the FPA. The Sensor provides stereo and imaging/spectroscopic measurements of reflected light from visible to medium wave-infrared (MWIR) wavelengths to characterize surface morphology, search for pyroclastic plumes, search for organics, identify salts and possible biominerals, characterize crystalline vs. amorphous ice and ice grain sizes, and map the distributions of key phases. In addition to addressing important geologic questions, these measurements support selection of a site for in situ sampling and analysis. A Data Processing Unit (DPU) performs mitigation of radiation that penetrates the shielding using sets of same-filter image frames or spectra of a single spot by removing image spatial pixels with radiation hits, and coadding the remainder for the same spatial pixel, improving signal-to-noise ratio (SNR). The DPU also performs onboard calibration of imager and spectrometer data, co-registration of multispectral images, and calculation of spectral index (“summary parameter”) images for efficient use of lander downlink. Co-registered multispectral image sets and spectra are retained onboard and can be downlinked upon query.

Comparison of In Situ‐Fabricated Ternary NiCoMn‐Metal–Organic Frameworks versus Slurry Deposition on Porous Ni‐Foam: A Facile Approach for Enhancing Supercapacitor Performance

Owing to the worldwide energy requirements, metal–organic frameworks (MOFs) have been extensively used as electrode material. Ternary MOFs have been of prime importance because of their characteristic of a variety of oxidation states than mono‐ and bimetallic MOFs. Herein, a novel comparison and superiority of binder‐free MOF deposition known as in situ (IN) on the substrate have been investigated over the slurry deposition method involving the excellent properties of ternary MOFs. Confirmation of MOF formation using X‐ray diffraction and investigation of its morphological features have been explored using field‐emission scanning electron microscopy. Energy dispersive X‐ray area mapping has also been integrated for conformity of uniform elemental distribution. The electrochemical properties of NiCoMn‐MOF have been investigated and the results obtained for NiCoMn deposited using IN methodology are superior due to excellent penetration of MOF inside substrate that provides the basis of excellent electrochemical properties. A specific capacitance of 1000 C g−1 at 4 A g−1 in 3‐electrode assembly has been achieved accompanied by energy and power density of 55 Wh kg−1 and 2467 W kg−1 in 2‐electrode setup. An excellent cyclic stability of about 97% has been obtained after subjecting the asymmetric supercapacitor device to 5000 charge/discharge cycles at 20 A g−1. Diffusive nature dominancy over capacitive is also observed by manipulating Dunns’ model. The superior and novel aspect of using IN deposition may pave the way for their efficient use in energy storage devices.

An innovative ocean thermal energy conversion system with zeotropic Rankine cycle and direct contact membrane distillation for enhanced efficiency and sustainability

This research introduces an integrated ocean thermal energy conversion water and power cogeneration system (OTEC-WPCS), combining a Zeotropic Rankine Cycle (ZRC) with Direct Contact Membrane Distillation (DCMD) for efficient power and water production. The hydrofluoroolefins (HFOs), chosen for their zero ozone depletion potential (ODP) and extremely low global warming potential (GWP), are used as working fluid components in the ZRC. Additionally, DCMD is implemented for freshwater generation. A mathematical model is established, incorporating both thermodynamic and CFD simulations. The goal is to identify optimal operating conditions that maximize the output of the system. By coupling DCMD and ZRC in series, the system's efficiency reaches 8.92 %, an improvement of 5.71 % compared to a standalone ZRC system. This configuration allows for more efficient use of surface seawater heat compared to an ammonia-based Organic Rankine Cycle (ORC)-DCMD system. The enhancements include an increase in power and water production per unit mass flow of surface seawater by 0.55 kW/(kg·s) and 30 %, respectively. Over 60 % of the system's exergy destruction occurs in the DCMD modules and evaporator, while nearly 80 % of the capital cost is associated with the evaporator, condenser, and DCMD heat exchanger. Enhancing the DCMD module structure and heat exchanger can improve both energy and exergy efficiency, and economic feasibility.

The Role of Transport in Formation of the «Advancement Effect» in Ancient and Medieval Societies

Transport has played a very significant role in formation and development of ancient and medieval civilisations. At the same time, since ancient times, the transport factor has contributed to advancement of various social communities and societies (manifested in achievement of leadership by the corresponding cities, regions, countries) and formation of the «advancement effect», the essence of which is the possibility of more efficient use of available resources and implementation of existing advantages to ensure successful development.The influence of transport on formation of the «advancement effect» of societies is based on a wide range of socio-economic effects that are generated during movement of goods and passengers. These include, inter alia, adding value to goods as a result of movement, stimulating growth in the volume, scale and efficiency of goods production, disseminating knowledge, ideas and stimulating innovation.Because of the effects generated by transport activities, the centres of this activity develop rapidly and achieve economic, and often also political and cultural leadership. At the same time, transport leadership is associated both with geographical location and with socio-economic (primarily institutional) conditions that provide the opportunity to implement the benefits of the geographical location.The provided analysis covering approximately five thousand years of existence of ancient and medieval civilisations, using many examples, showed that transport indeed played an important role in advancement of certain societies localised within cities, regions and countries. Their advancement to leadership positions was achieved due to the synergy of an advantageous geographical location, innovative development of technical means of transport and institutions that facilitate the efficient conduct of transport activities and development of transport and commercial ecosystems. In turn, the cessation or significant weakening of the beneficial effects of the transport factor led to the loss of leadership positions by societies and the decline of the corresponding economic centres.

An Implementation of Lighting Control Systems Buildings with Time Based Mapping and AC Light Dimmer Integrated IoT

The use of a building lighting control system is very necessary to regulate lighting in a building to suit needs, because not only low lighting conditions can cause discomfort, lighting conditions that are too bright can also cause discomfort. The problem is that natural light cannot play much of a role in lighting buildings which are generally closed and have minimal ventilation, as well as the availability of lighting which, if not controlled properly, cannot directly meet the lighting needs of the building, whether it is the value of the light intensity produced, mapping the lighting of the lights, setting the duration of the use of lights as lighting or in the case of excessive lighting by turning on all the available lights in the room becomes a problem in terms of efficient use of electrical energy, so a special system design is needed to overcome this problem, namely the implementation of a building lighting control system. with time-based mapping and an AC light dimmer integrated with the Internet of Things which has a specific purpose as a system for controlling building lighting to suit needs, whether it is setting the light intensity value, mapping the use of lights or setting the time of use of lights as lighting. The test results have shown that the implementation system for the building lighting control system with time-based mapping and AC Light Dimmer which has been integrated with the Internet of Things as remote control and monitoring communication has been successfully implemented and is working well according to the specified targets. Keywords: lighting, AC light dimmer, mapping, Internet of Things.

Energy-use efficiency of organic and conventional plant production systems in Germany

Sustainable and efficient energy use in agriculture helps tackle climate change by reducing fossil energy use. We evaluated German farming systems by analysing energy input and output. Data from 30 organic and 30 conventional farms (12 arable, 18 dairy farms each) between 2009 and 2011 was used. Energy input, output, and the influence of farm type, farm structure, and management intensity on energy-use efficiency (EUE) were analysed for crop production using the farm management system REPRO. Conventional farms (CF) always had higher energy input. The energy input for organic farms (OF) was 7.2 GJ ha−1 and for CF 14.0 GJ ha−1. The energy output of CF was also higher. Reductions were higher in energy input than in energy output. In 73.3% of the farm pairs, OF were more energy efficient than CF. The EUE was comparable with CF on 10% of OF and for 16.7% of CF the EUE was higher suggesting better fossil energy utilization. EUE can be increased when reducing fossil energy inputs through more efficient machinery, reduction of agrochemicals, precision farming, the use of renewable energy or energy retention, and by increasing yields. A reduction of inputs is urgently required to lower the (political) dependence on fossil energy.

A Fast, Convenient, Polarizable Electrostatic Model for Molecular Dynamics.

We present an efficient polarizable electrostatic model, utilizing typed, atom-centered polarizabilities and the fast direct approximation, designed for efficient use in molecular dynamics (MD) simulations. The model provides two convenient approaches for assigning partial charges in the context of atomic polarizabilities. One is a generalization of RESP, called RESP-dPol, and the other, AM1-BCC-dPol, is an adaptation of the widely used AM1-BCC method. Both are designed to accurately replicate gas-phase quantum mechanical electrostatic potentials. Benchmarks of this polarizable electrostatic model against gas-phase dipole moments, molecular polarizabilities, bulk liquid densities, and static dielectric constants of organic liquids show good agreement with the reference values. Of note, the model yields markedly more accurate dielectric constants of organic liquids, relative to a matched nonpolarizable force field. MD simulations with this method, which is currently parametrized for molecules containing elements C, N, O, and H, run only about 3.6-fold slower than fixed charge force fields, while simulations with the self-consistent mutual polarization average 4.5-fold slower. Our results suggest that RESP-dPol and AM1-BCC-dPol afford improved accuracy relative to fixed charge force fields and are good starting points for developing general, affordable, and transferable polarizable force fields. The software implementing these approaches has been designed to utilize the force field fitting frameworks developed and maintained by the Open Force Field Initiative, setting the stage for further exploration of this approach to polarizable force field development.

Natural deep eutectic solvents-based green extraction of vanillin: optimization, purification, and bioactivity assessment.

The sustainable extraction of natural compounds has recently attracted significant attention. The extraction of high-quality natural vanillin in active form is crucial for its efficient use in various industries, but conventional solvents are not suitable for this purpose. The flammability, volatility, and toxicity of organic solvents can harm extraction personnel, and their waste liquid can cause environmental pollution. Natural deep eutectic solvents (NADES) are cost-effective, environmentally friendly, biodegradable, and non-toxic organic alternative to conventional solvents. In this study, 20 different NADES were tested for the sustainable extraction of natural vanillin. Among these, a DES system composed of choline chloride: 1,4-butanediol: lactic acid exhibited the highest extraction rate (15.9 mg/g). Employing response surface methodology (RSM), optimal extraction conditions were determined, yielding a vanillin content 18.5 mg/g with water content of 33.9%, extraction temperature of 64.6°C, extraction time of 32.3 min, and a solid-liquid ratio of 44.9 mg/mL. Subsequently, the optimized NADES system was then assessed for reusability in extracting vanillin from vanilla pods and kraft lignin over three cycles, retaining 43% of its extraction efficiency and demonstrating potential for waste reduction. Purification of vanillin was achieved through chromatography using a non-polar resin SP700, with ethanol as a desorption eluent and a feed solution pH of 4.0, resulting in the highest vanillin purity. HPLC and GC-MS analyses confirmed purity, while antioxidant activity assays (DPPH and ABTS) showcased significant antioxidant activity of the purified vanillin. Moreover, vanillin exhibited notable antimicrobial activity against a panel of food-borne bacteria. This study introduces an environmentally friendly approach to vanillin extraction highlights using NADES, emphasizing the potential for producing high-quality bioactive vanillin with reduced environmental impact. The applicability of NADES systems extends beyond vanillin, offering a versatile method for extracting diverse natural compounds.

Research on Land Use Versatility Evaluation, Spatiotemporal Coupling, and Influencing Factors Based on Multimethod Integration

Land use multifunctionality research is important for the efficient use of land resources and the resolution of land use conflicts. With the use of methods such as the technique for order of preference by similarity to ideal solution (TOPSIS) model, coupling coordination model, and geographical detector, the land use multifunctionality level, spatiotemporal coupling, and influencing factors in the Sichuan Province of China from 2000 to 2020 were systematically analyzed in this paper. It was revealed that, from 2000 to 2020, the comprehensive land use functionality in Sichuan Province was continuously improved with increasing economic, social, and ecological functionality levels. The comprehensive land use functionality in each city (prefecture) exhibited a positive development trend. The coupling coordination degree of the land use multifunctionality in Sichuan Province has been continuously improved, undergoing an evolutionary process from the brink of disarray to barely coordinated, then to primary coordination, and finally to medium coordination. The spatial differentiation of land use multifunctionality coupling coordination among cities (prefectures) was notable, showing center–periphery spatial distribution characteristics. The average slope and employed population density exhibited the highest explanatory power for the spatial differences in land use multifunctionality coupling coordination. The interaction between any two factors exerted a greater impact than any single factor on the spatial differentiation of land use multifunctionality coupling coordination. Based on the regional development characteristics, region-specific strategies should be adopted to enhance the land use multifunctionality level in Sichuan Province.

Biobanking Legislation in Spain: Advancing or Undermining Its Ethical Values?

Biobanks are important resources for improving public health and individual care. Some legal frameworks can be more or less conducive to advancing the potential benefits of biobanks. The purpose of this article is to assess biobanking legislation and practices in Spain to determine how well they fare in such a regard. We focus here on some of the primary ethical values that ground relevant legislation and that we believe are consistent with promoting biobanking benefits: the value of scientific research; efficient use of scarce resources; and respect for the dignity of donors. We argue that although Spanish regulations advance these values in important ways, they also have provisions that undermine them and thus risk limiting the potential benefits of biobanks. We offer some suggestions for improvement.

Development and testing of an allterrain wheelchair built with light magnesium alloy to improve the mobility of the rural population

The objective of this work was to design and test an all-terrain wheelchair for the rural population, implementing an AZ31 magnesium alloy and a lever propulsion mechanism to reduce the effort made during mobility. Two wheelchair prototypes were evaluated under the ISO7176 standard and usability testing. To validate the fact that the wheelchair weight reduction represents a benefit, a repeated measures study was carried out to establish the effect of the material change on mobility efficiency. The tests were carried out in an academic campus in Colombia in an open space with a surface covered with grass, unevenness, and other obstacles to emulate the conditions of a rural environment. A convenience sample was used, randomly selecting 17 subjects from the academic community without disabilities or overweight. Two prototypes were manufactured, one in aluminum and the second in magnesium alloy. For the study of repeated measurements, each participant had to complete three tests with both prototypes: a short-dis ance test, an obstacles test, and a long-distance test, which were performed randomly. The magnesium alloy prototype achieved a 25% weight reduction. In ISO7176 testing, both prototypes maintained their structural integrity and functionality. Also, with a confidence of 95%, it was possible to establish that with the magnesium prototype, the users traveled a greater distance in the same time. The new design meets the needs of mobility, support, and comfort of users, making efficient use of magnesium alloy. Weight reduction in the wheelchair allows the user to save time on mobility or cover greater distances with less physical effort. This is a starting point to offer a contextualized and affordable product to the Latin American population.

Evaluation of the urban Land use plan’s effectiveness in achieving resource efficiency: the case of Bahir Dar city- Ethiopia

ABSTRACT Urban land use plans (ULUPs) contribute to the efficient use of resources for sustainable urban development. However, the metered contribution of Bahir Dar’s ULUPs to the efficient use of resources has not yet been known. Bahir Dar is the capital of the Amhara Region and a scenic city on the southern shore of Lake Tana, Ethiopia’s largest lake and the source of the Blue Nile. It attracts many visitors from inside and outside the country. This study evaluates the effectiveness of ULUPs in Bahir Dar to achieve efficient use of resources such as water, energy, and food. Thus, the study developed criteria to assess the effectiveness of ULUPs based on the global indicator framework for the Sustainable Development Goals (SDGs). The results show that its ULUPs were not resource efficient in terms of food production, water quality and yield, and transport energy usage.

Hyperspectral Imaging of Soil and Crop: A Review

The remote sensing is one of the precision technologies, can be used to monitor and assess the target area or object such as soil, crop, and water. Hyperspectral imaging (HSI), also known as imaging spectrometry or hyperspectral remote sensing, is a combined technique of spectroscopy and imaging system for sensing spectral information of an area or object. It involves capturing images of an object using multiple distinct optical bands that cover a wide range of the electromagnetic spectrum (350-2500 nm). The hyperspectral bands are continuous, narrow, and contagious and contain hundreds and thousands of numbers. Hyperspectral remote sensing is particularly valuable for gathering precise and up-to-date information necessary for agricultural planning and precision farming. HSI technology is the employment of hyperspectral sensors aids in analyzing soil physical (bulk density, texture, water content), chemical (pH, EC, SOC, and macro and micro nutrients), biological (SOM) properties and helps to categorize different crop varieties, identify pests and diseases, and assess crop yield and water stress in plants. The spectral reflectance of soil is affected by its properties such as mineral composition (Fe oxides), organic matter, soil moisture, and texture. For example, the spectral reflectance will be more if soil has less organic matter. The chemical bonds of soil molecules interact with the electromagnetic spectrum, and produce distinct pattern of reflectance. But the data collected from hyperspectral imaging are required big storage due to its large amount of data and finding the most appropriate hyperspectral image classification algorithm is a challenging task. So, these problems should be solved in future and national soil spectral library is needed for calibration of models which helps for efficient use of hyperspectral imaging technology.

The long-term effect of Fe3O4 in activating persulfate to degrade refractory organic contaminants for groundwater remediation

Highly reactive metal-based materials for persulfate activation have been intensively studied for treatment of groundwater contaminants. However, the long-term efficacy of the readily available metal-oxide additives, which can be more important for groundwater remediation practice, has received minimal attention. In this study, the results of preliminary experiments demonstrated that Fe3O4 was superior to seven metal oxides (MnO, Fe2O3, MnO2, CuO, Cu2O, CoO, NiO) and zero-valent iron for activating persulfate to degrade 1,2-dichloropropane. Experiments were then conducted to examine the long-term effects of Fe3O4-activated persulfate degradation of four contaminants, i.e., 1,2-dichloropropane, 1,1,2-trichloroethane, 1,4-dioxane, and methyl tert-butyl ether (MTBE). The system achieved complete removal of the contaminants in approximately 72 h, which was contrasted to a removal efficiency less than 35 % in the absence of Fe3O4. Highly efficient use of persulfate for contaminant degradation was observed with insignificant production of soluble Fe before depletion of the contaminants. Production of sulfate radical (SO4•−) and hydroxyl radical (HO•) via surface reactions was likely the process responsible for the degradation. Ten and five cycles of 1,2-dichloropropane degradation experiments were conducted in deionized water and actual groundwater. These results suggested that the Fe3O4 could retain 80 % of its original activation capacity after 5 cycles, but partial oxidation of Fe3O4 eventually occurred. Production of some Cl-containing degradation-resistant intermediates from degradation of 1,2-DCP was observed and could be mitigated under specific conditions. The results show that Fe3O4 has a long-term effect in activating persulfate for contaminant degradation, which is promising for applications such as permeable reactive barriers and nanoparticle injection for groundwater remediation.

Economic Growth in the Age of Ubiquitous Threats: How Global Risks are Reshaping Growth Theory

Abstract One of the most outstanding accomplishments of the economic science over the last decades is the development of a sound and coherent theory of economic growth. Research in growth theory has demonstrated that significant and systematic increases in well-being are attainable whenever the right formula is implemented. When combined with efficiency, the ingredients of this formula – innovation, the diffusion of ideas, and human capital accumulation – can drive the economy toward a virtuous path of sustained growth. Notwithstanding, this is an overly optimistic view of growth that does not account for the many obstacles that the creation of wealth may encounter. The current essay surveys cutting-edge research on growth theory to conclude in favor of a paradigm shift: the main concern is no longer just with how to correctly combine production inputs, but with how their efficient use is eventually hampered by a large collection of worldwide risks and threats. Global risks come in many shapes (they can be classified as economic, environmental, geopolitical, societal, and technological) but, in any case, they call for a reexamination of growth theory.

Irrigation Scheduling and Cultivar Management for Increasing Water Productivity under Dryland Condition: A Review

In Dryland environments with limited water resources, irrigation scheduling and cultivar management are play pivotal roles in enhancing water productivity. Effective irrigation scheduling involves the judicious timing and amount of water application, considering factors such as soil moisture levels and crop growth stages. Utilizing advanced technologies, such as soil moisture sensors and remote sensing, facilitates precise irrigation management. This approach not only conserves water but also prevents waterlogging and salinity issues, promoting optimal plant growth. Cultivar selection is another critical aspect, focusing on identifying and cultivating crops that are well-adapted to arid conditions. Drought-resistant cultivars with traits like deep root systems and efficient water use contribute significantly to water productivity. Integrating modern breeding techniques and genetic engineering enhances the development of cultivars with improved drought tolerance, ensuring resilience in dryland agriculture. Furthermore, the implementation of agro ecological practices, such as conservation tillage and organic farming, complements irrigation scheduling and cultivar management. These practices enhance soil structure, water retention, and overall ecosystem health, fostering a more sustainable and resilient agricultural system. Adopting a comprehensive approach that combines precise irrigation scheduling, resilient cultivar selection and agro ecological practices holds great potential for increasing water productivity in dryland conditions. This integrated strategy not only addresses the challenges posed by water scarcity but also contributes to the long-term viability of agriculture in arid regions.
