Opis:: For purposes of studying the heat transfer behavior of various fluids in a refrigeration system, a dynamic model is established, obtained on the basis of analysis concerning the effects of adsorption velocity, adsorbent bed temperature, condensing temperature, and heat transfer fluids, as well as changes of external conditions. It is demonstrated that adsorption velocity increases sharply in the initial phase of adsorption process and gradually declines after reaching a peak value, whereas condensing temperature increases sharply in the initial phase of desorption process and decreases after reaching a peak value with the desorption quantity decreasing. Furthermore, the increase of heat source temperature and the decrease of cooling water temperature can advance the adsorption process. The present study therefore suggests some ways of improving the performance of such a refrigeration system by increasing heat source temperature, decreasing ambient air temperature, increasing return air temperature and decreasing cooling water temperature.

Opis:: An increasing proportion of the world’s population lives in urban settings that have limited greenspace. Urbanization puts pressure on existing greenspace and reduces its access. Climate impacts, including increased temperature and extreme weather events, challenge the maintenance of urban vegetation, reducing its ecosystem services and benefits for human health. Although urban greenspace has been positively associated with numerous health indicators, the evidence for allergies and respiratory health is much less clear and mixed. To address these uncertainties, a workshop with 20 global participants was held in Munich, Germany, in May 2024, focusing on the impact of greenspace-related co-exposures on allergies and respiratory health. This narrative review captures key insights from the workshop, including the roles of urban greenspace in (1) climate change mitigation, (2) interactions with pollen, and (3) emissions of biogenic volatile organic compounds and their byproducts, such as ozone. Additionally, it presents research and stakeholder recommendations from the workshop. Future studies that integrate advanced greenspace exposure assessments and consider the interplay of greenspace with pollen and biogenic volatile organic compounds, along with their relevant byproducts are needed. Increased public awareness and policy actions will also be essential for developing urban greenspace that maximizes health benefits, minimizes risks, and ensures resilience amid a changing climate and rapid urbanization.

Opis:: Powszechnie przyjęte założenie, że każda ważna informacja naukowa jest dostępna w języku angielskim, przyczynia się do niedostatecznego wykorzystania wiedzy dostępnej w innych językach. Można jednak przypuszczać, że nieanglojęzyczne źródła naukowe przynoszą unikalne i cenne informacje, zwłaszcza w dyscyplinach, w których wiedza jest niepełna, oraz dla nowych problemów, gdzie synteza dostępnych faktów jest pilnym wyzwaniem. Jednak taki wkład wiedzy niedostępnej w języku angielskim i zastosowanie nauki rzadko jest określone ilościowo. W tym opracowaniu dowodzimy, że badania opublikowane w lokalnych językach dostarczają podstawowej wiedzy dotyczącej ochrony bioróżnorodności na świecie. Spośród przeanalizowanych 419 679 recenzowanych artykułów naukowych w 16 językach, zidentyfikowaliśmy 1234 nieanglojęzyczne publikacje dostarczające dowody na skuteczność interwencji na rzecz ochrony bioróżnorodności, w porównaniu z 4412 anglojęzycznymi badaniami, które spełniały te same kryteria. Takie nieanglojęzyczne prace są publikowane coraz częściej w sześciu z 12 języków, w których była wystarczająca liczba spełniających kryteria badań. Uwzględnienie badań nieanglojęzycznych może wzbogacić informacje anglojęzyczne poprzez rozszerzenie zasięgu geograficznego (tj. liczby komórek siatki $2^{\circ}$ × $2^{\circ}$ wraz z odpowiednimi badaniami) o 12-25%, zwłaszcza w regionach różnorodnych biotycznie, oraz zasięgu taksonomicznego (tj. liczby gatunków objętych odpowiednimi badaniami) o 5-32%, pomimo, że zazwyczaj opierają się one na mniej solidnie zaplanowanych badaniach. Nasze wyniki dowodzą, że synteza badań nieanglojęzycznych jest kluczem do przezwyciężenia powszechnego braku lokalnych, zależnych od kontekstu wyników i ułatwienia ochrony przyrody opartej na danych z całego świata. Postulujemy, aby wykorzystywać potencjał naukowych źródeł nieanglojęzycznych do nowej i rygorystycznej oceny w podejmowaniu decyzji dotyczących innych niż ochrona bioróżnorodności globalnych wyzwań.
The widely held assumption that any important scientific information would be available in English underlies the underuse of non-English-language science across disciplines. However, non-English-language science is expected to bring unique and valuable scientific information, especially in disciplines where the evidence is patchy, and for emergent issues where synthesising available evidence is an urgent challenge. Yet such contribution of non-English-language science to scientific communities and the application of science is rarely quantified. Here, we show that non-English-language studies provide crucial evidence for informing global biodiversity conservation. By screening 419,679 peer-reviewed papers in 16 languages, we identified 1,234 non-English-language studies providing evidence on the effectiveness of biodiversity conservation interventions, compared to 4,412 English-language studies identified with the same criteria. Relevant non-English-language studies are being published at an increasing rate in 6 out of the 12 languages where there were a sufficient number of relevant studies. Incorporating non-English-language studies can expand the geographical coverage (i.e., the number of $2^{\circ}$ × $2^{\circ}$ grid cells with relevant studies) of English-language evidence by 12% to 25%, especially in biodiverse regions, and taxonomic coverage (i.e., the number of species covered by the relevant studies) by 5% to 32%, although they do tend to be based on less robust study designs. Our results show that synthesising non-English-language studies is key to overcoming the widespread lack of local, context-dependent evidence and facilitating evidence-based conservation globally. We urge wider disciplines to rigorously reassess the untapped potential of non-English-language science in informing decisions to address other global challenges.

Opis:: A series of derivatives of azetidine were designed by stepwise replacing the hydrogen atoms of azetidine with nitroimine groups. At the G3MP2 level, the heats of formation (HOFs), bond dissociation energies (BDEs), molecular densities (ρ0), detonation velocities (D), and detonation pressures (P) of the nitroimine-substituted azetidines were investigated to look for high-energy-density compounds (HEDCs). It was found that the nitroimine-substituted azetidines have high HOFs and large BDEs, and sufficient thermal and kinetic stability. Furthermore, the covalent bond strength in the four-membered ring, accompanied by intramolecular hydrogen bonds, are the determining factors for isomer stability. Based on our calculations, derivatives E and F have better detonation performance than RDX and can be regarded as potential high-energy-density compounds. This work may provide basic information for further study of the title compounds.

Opis:: Against the background of increasing installed capacity of wind power in the power generation system, high-precision ultra-short-term wind power prediction is significant for safe and reliable operation of the power generation system. We present a method for ultra-short-term wind power prediction based on a copula function, bivariate empirical mode decomposition (BEMD) algorithm and gated recurrent unit (GRU) neural network. First we use the copula function to analyze the nonlinear correlation between wind power and external factors to extract the key factors influencing wind power generation. Then the joint data composed of the key factors and wind power are decomposed into a series of stationary subsequence data by a BEMD algorithm which can decompose the bivariate data jointly. Finally, the prediction model based on a GRU network uses the decomposed data as the input to predict the power output in the next four hours. The experimental results show that the proposed method can effectively improve the accuracy of ultra-short-term wind power prediction.

Opis:: In this work, low rank coal was used for the removal of nonylphenol ethoxylate with fifteen ethylene oxide groups (NPEO15) from aqueous solutions at different contact times, temperatures, and initial adsorbent concentrations. The adsorption isotherms showed good fit with the Langmuir equation. Maximum adsorption capacities calculated at 308, 318, and 328 K were 23.64, 29.41, and 35.71 mg g–1, respectively. The changes in the free energy of adsorption (ΔG°), enthalpy (ΔH°), and entropy (ΔS°) were calculated in order to predict the nature of adsorption. The results of the thermodynamic analysis indicated that a spontaneous process took place, driven synergistically by both enthalpy and entropy. The adsorption kinetics of NPEO15 were consistent with a pseudo-second order reaction model. XPS results showed that the oxygen functional groups on the low rank coal surface were significantly covered by NPEO15. Furthermore, while the content of C–C/C–H functional groups increased significantly, that of C–O functional groups decreased after absorption. These results clearly indicate that low rank coal is more hydrophobic and displays better floatability.

Opis:: A CO₂ boiled off gas (CO₂ BOG) reliquefaction system using liquid ammonia cold energy is designed to solve the problems of fuel cold energy waste and the large power consumption of the compressor in the process of CO₂ BOG reliquefaction on an ammonia-powered CO₂ carrier. Aspen HYSYS is used to simulate the calculation, and it is found that the system has lower power consumption than the existing reliquefaction method. The temperature of the heat exchanger heater-1 heat flow outlet node (node C-4) is optimised, and it is found that, with the increase of the node C-4 temperature, the power consumption of the compressor gradually increases, and the liquefaction fraction of CO₂ BOG gradually decreases. Under 85% conditions, when the ambient temperature is 0°C and the temperature of node C-4 is -9°C, the liquid fraction of CO₂ BOG reaches the maximum, which is 74.46%, and the power of Compressor-1 is the minimum, which is 40.90 kW. According to this, the optimum temperature of node C-4 under various working conditions is determined. The exergy efficiency model is established, in an 85% ship working condition with the ambient temperature of 40°C, and the exergy efficiency of the system is the maximum, reaching 59.58%. Therefore, the CO₂ BOG reliquefaction system proposed in this study could realise effective utilisation of liquid ammonia cold energy.

Opis:: Abnormal iris mechanical properties have been considered to be an important cause of pupillary-block and angle-closure glaucoma. In this research, viscoelasticity, anisotropy and location-dependence of mechanical properties of rabbit iris were investigated using uniaxial tensile test. Methods: Iris strips were taken along three directions: inner-circumferential direction (ICD), outer-circumferential direction (OCD) and radial direction (RD), respectively. Quasi-static tensile tests and stress–relaxation tests were applied on the iris strips. Then, the stress–stretch data was fitted with third order Ogden model; the stress–relaxation data was fitted with the third order Prony series model. Through comparing the tangent modulus and relaxation limit of the strips from different directions and locations, the viscoelasticity, anisotropy and location-dependence of mechanical properties of rabbit iris were explored. Results: The tangent moduli of iris at the stretch of 1.05 along ICD, OCD, and RD were 3.2 ± 1.4 kPa, 4.2 ± 2.6 kPa, 1.5 ± 0.8 kPa, respectively. Iris strips in ICD and OCD were found to have almost the same stress–relaxation behavior, and both relaxed slower than iris strips in RD. Conclusions: The mechanical properties of the iris were typically nonlinear, viscoelastic, anisotropic and location-dependent. The stress growth rate of the circumferential direction iris strip is significantly lower than that of RD and the stress–relaxation rate is significantly higher than that of the RD. That is, the iris is more prone to deformation in RD and the stress–retention ability after deformation in RD is weak, which is consistent with the fact that the iris bombe more likely happens in RD in vivo. The results of this study may also help us to establish a more accurate finite element model to simulate the flow field of humor aqueous and find the key factor of pupillary-block.

Opis:: A lightning protection system (LPS) of an urban 110 kV substation is designed and analysed according to NFPA 780 and IEC 62305-3 standards. The analysis of the LPS is established on the value of risk assessment. The total area of the plant is described by one soil layer with uniform resistivity. This study aims to improve the understanding of an unexpected manner of the grounding system beneath lightning currents by clarifying the basic concepts of the lightning protection level and the new design procedure in this paper was clarified according to NFPA-780 level 1 for a lightning protection system. The program is integrated with the CDEGS software, which provides effective geometrical modeling with object and result visualization. Furthermore, module and automated fast Fourier transform (FFT) is implemented in this study to simulate electromagnetic fields in the time and frequency domains. These current values are compared to the desired protection levels within the standards. The study results show that for the improved protection of the system against lightning, the total power grid must be considered as a source of improvement for studying shielding influence and the protection levels provided inside this substation.

Opis:: The development of low-cost organic/inorganic puncture-resisting composites is suggested to improve their puncture resistance and thermal insulation properties. In this paper, recycled high modulus Kevlar fiber and glass fabric were used together with polyester/lowmelting polyester nonwovens. The result shows that the static puncture resistance improves proportionally with Kevlar fibers; but the dynamic puncture resistance remains the same at first and then rises up to 20 wt % for Kevlar fibers. The increasing low-melting polyester fibers on the surface result in an upward and then downward trend for both static and dynamic puncture resistances. The additional polyester/low-melting polyester nonwovens are beneficial for the improvement of puncture resistances. Moreover the thermal conductivity of all the composites is in range of 0.015-0.025 W/m·K. According to the results, Kevlar fibers are also shown to be advisable reinforcement to achieve better tensile and bursting strengths.
Badano możliwości zwiększenia odporności na przebicie oraz odporności termicznej tanich organiczno-nieorganicznych kompozytów. W badaniach stosowano wysoko modułowe włókna Kevlar z recyklingu oraz tkaninę z włókien szklanych łącznie z włókninami wykonanymi z niskotopliwego poliestru. Stwierdzono, że statyczna wytrzymałość na przebicie zwiększa się proporcjonalnie z ilością włókien Kevlar, ale dynamiczna wytrzymałość na przebicie pozostaje początkowo taka sama, a następnie wzrasta do zawartości włókien Kevlar 20%. Zastosowanie niskotopliwych włókien poliestrowych powoduje tendencje wzrastające, a następnie malejące dla wytrzymałości statycznej i dynamicznej. Stwierdzono, że dodatek włókien Kevlar jest korzystny dla wytwarzanych kompozytów.
