Enhancing prediction of elemental composition through machine learning decision tree models for biomass gasification optimization
Authors: Xu Peng , Zhang Jidong 
Published: September 2024

Abstract
The worldwide transition to cleaner, sustainable energy sources, prompted by population growth and industrialization, responds to uncertain fossil fuel prices and environmental concerns, highlighting the substantial benefits of renewable energy in reducing greenhouse gas emissions and addressing climate change. Derived from non-fossilized organic materials, biomass emerges as a significant and sustainable contributor to renewable energy. Its diverse nature is complemented by a range of conversion technologies, encompassing combustion, pyrolysis, gasification, and liquefaction, providing versatile avenues for biomass energy transformation. Gasification, the transformative process of converting organic matter into combustible gases under controlled oxygen levels, is accomplished through direct oxygen supply or pyrolysis. This method yields a dependable gaseous fuel versatile for heating, industrial processes, power generation, and liquid fuel production. Machine learning employs advanced statistical techniques for modeling across diverse industries, showcasing particular efficacy in optimizing thermochemical processes by precisely identifying the optimal operating conditions required for achieving desired product properties. These models utilize proximate biomass data to predict the elemental compositions of N2 and H2. Assessment of both single and two hybrid models indicated that the introduced optimizers significantly enhanced the estimation of N2 and H2 when combined with Decision Tree (DT), with Decision Tree Coupled with Artificial Hummingbird Algorithm (DTAH) proving particularly effective. Notably, DTAH demonstrated outstanding performance with remarkable R
2 values of 0.990 for N2 and 0.992 for H2. Additionally, the minimal Root Mean Square Error (RMSE) values of 1.291 and 1.550 for N2 and H2 predictions respectively underscore the precision of DTAH, establishing it as a suitable choice for practical real-world applications.

Abstract
Debris flow is one of the most common types of geological disasters in China. Owing to the influence of topography, geomorphology, geological conditions, human activity, and rainfall debris flow disasters frequently occur in the mountainous areas of Beijing. The research on debris flow in the Beijing area focuses on rainfall and risk evaluation, material sources, and early warning and prevention of debris flow. However, there are few studies on the development characteristics of single-gully debris flow and the prediction of hazardous areas in the Beijing area. Therefore, we chose the debris flow of Bangou Village in Yanqing District of Beijing as the research object. We analyzed the recharge conditions in the ditch domain and predicted the extent of the hazardous area around the gully, providing suggestions for control measures. The dynamic reserves of the loose deposits in the debris flow gully, currently in the development stage, were estimated as 15.48 × 104 m3, representing four supply sources: artificial deposits, alluvium and diluvium, residual slope deposits, and collapse. The peak flow is 24.49 m3/s for a 10-year rainfall event, 27.64 m3/s for a 20-year rainfall event, 31.79 m3/s for a 50-year rainfall event, and 34.93 m3/s for a 100-year rainfall event. The total amounts of solids washed out by a debris flow from the preceding events are 0.70 × 104 m3, 0.79 × 104 m3, 0.91 × 104 m3, and 1.00 × 104 m3, respectively. The size of the debris flow is small, with a maximum hazardous area of 0.2810 km2. We conclude that a small debris flow outbreak in the Bangou Village gully is possible. We expect that the results of this study will provide basic information and help improve debris flow research in Beijing.

Abstract
The objective of the study is to investigate the current state of the canyons in the northern part of Montenegro, their potential for sustainable development, which could be achieved through canyoning as an attractive tourist attraction, and to assess the area’s geotourism potential. The canyons encompassed in this research are the Nevidio Canyon, the Tara Canyon, the Grlja Canyon, and the canyon of the river Ibar. The research was carried out using the modified Geosite Assessment Model, which includes tourists’ opinions on the significance of indicators in the assessment process. The obtained results show that all four canyons possess significant scientific, educational, and aesthetic values for the development of canyoning tourism. Since surveyed tourists pointed out not only the advantages but disadvantages of these geosites, these findings should be further used for the valorization and geoconservation of the geosite and provide a more favorable deal for the arrival of as many tourists as possible. In the future, investigated geosites should be improved with tourist content and activities, such as interpretive boards for tourists, expert guides, organized visits, tourist infrastructure, and promotion. Successful activities in these critical areas could contribute to sustainable geotourism being one of the key economically beneficial activities of the local population that will develop local communities through the arrival of a larger number of domestic and foreign tourists.
The count-mass distinction in Hong Kong Sign Language: an intra- and cross-modal comparison
Authors: Koenders Emily 
Published: September 2024

Abstract
This article is in part an intra- and cross-modal comparison of the count-mass distinction (CMD) in Hong Kong Sign Language (HKSL). For the intra-modal analysis, HKSL data are compared to data found in Koulidobrova’s (2021) work on the CMD in American Sign Language/ASL (Koulidobrova, Elena. 2021. Counting (on) bare nouns: Revelations from American Sign Language. In Tibor Kiss, Francis Jeffry Pelletier & Halima Husić (eds.), Things and Stuff: The Semantics of the Count-Mass Distinction, 213–231. Cambridge: Cambridge University Press). According to Koulidobrova, the existing diagnostics used in spoken language research are insufficient to bring to light CMDs in sign languages. ASL’s CMD is visible in the failure to conjoin count and mass nouns and in the ungrammaticality of partitive constructions containing mass nouns. HKSL and ASL differ from each other in a few respects, among which the two aforementioned ASL diagnostic criteria. Regarding the cross-modal comparison, HKSL and ASL belong to different categories in Chierchia’s (2010) count-mass typology (Chierchia, Gennaro. 2010. Mass nouns, vagueness and semantic variation. Synthese 174. 99–149). Chierchia’s typology is based on CMDs in spoken languages. ASL is a number-neutral language (Type III), whereas HKSL is a number marking language (Type I) and thus patterns with languages like English and Dutch. The CMD in HKSL is visible in its failure to combine mass nouns directly with numerals and count adjectives without the intervention of a classifier. Based on my data analysis, I can furthermore argue that HKSL is a number marking language but that its plural number marking is realised through zero marking.

Несмотря на увеличение вклада комплексных подходов к переработке отходов лесной промышленности и растениеводства, основным способом утилизации отходов растительного сырья до сих пор является сжигание, что приводит к потерям ценных веществ. Альтернативным и прогрессивным способом переработки растительных отходов выступает экстракция с получением полезных веществ. В работе обобщены ранее опубликованные данные по экстракционным способам извлечения ценных веществ из древесных отходов и соломы различных культур в промышленных и лабораторных условиях. Систематизированы данные по химическому составу отходов лесной промышленности и растениеводства, а также содержанию химических соединений, имеющих потенциальную практическую ценность. Описаны основные подходы к извлечению из отходов растительного сырья таких ценных компонентов, как лигнин, фурфурол, воски, органические кислоты, полифенолы, красители, диоксид кремния и другие ценные вещества.
Despite the increasing contribution of integrated approaches to processing waste from the forest industry and crop production, the main method of recycling plant wastes is still combustion, which leads to losses of valuable substances. An alternative and advanced way of plant waste processing is extraction to obtain useful substances. The previously published data on the extraction-based methods to isolate valuable substances from wood waste and straw of various crops under industrial and laboratory conditions are generalised in this work. The data on the chemical composition of wastes from forest industry and crop production, as well as on the content of chemical compounds of practical significance are systematised. The basic approaches to retrieve such valuable components as lignin, furfural, waxes, organic acids, polyphenols, dyes, silicon dioxide and others from plant wastes are described.

Методом ЯМР 19F рассчитаны электронные эффекты ксенонсодержащих заместителей XeY, [Xe+] и [XeF2+] в растворителях разной природы. Полученные результаты позволяют отнести эти заместители к сильнейшим -электроноакцепторам ввиду сильного положительного индуктивного эффекта, тогда как резонансный эффект невелик.
The electronic effects of xenon-containing substituents XeY, [Xe+] and [XeF2+] in different solvents were calculated using the 19F NMR method. The results obtained allow us to classify these substituents as the strongest σ-electron acceptors due to the strong positive inductive effect, while the resonance effect is small.

Хелаторы на основе терпеновых бис(-аминооксимов), нанесенные на малополярные сорбенты (уголь, Сибунит, Полисорб), являются эффективными селективными экстрагентами для извлечения палладия и золота из кислых водных растворов, содержащих смеси благородных металлов и 3d-элементов. Применение сорбентов, импрегнированных новыми хелаторами, позволяет провести экстракцию в режиме жидкость–твердое, не прибегая к использованию какого-либо органического растворителя.
Chelators based on terpene bis(α-amine oximes) applied onto low-polar sorbents (coal, Sibunit, Polysorb) are effective selective extractants for the extraction of palladium and gold from acidic aqueous solutions containing the mixtures of precious metals and 3d-elements. The use of sorbents impregnated with the new chelators allows extraction in the liquid–solid mode without using any organic solvent.

Гидрохимический мониторинг водных объектов позволяет получить информацию об их состоянии в изучаемый период и оценить влияние климатических факторов на режим водоема. В последнее десятилетие возрастает актуальность работ по изучению влияния криогенных процессов на ионный состав малых тундровых озер в российском Заполярье. Статистически установлено воздействие межгодовых колебаний температуры воздуха и осадков на ионный состав озер: изменяется содержание ионов NO2, SO4, NO3. Активная термоденудация по берегам озер увеличивает общую минерализацию в среднем на 42.8 % и изменяет концентрацию ионов Na, Ca, Mg, K, PO4, HCO3.
Hydrochemical monitoring of inland waters makes it possible to obtain information about their state and to assess the influence of climatic factors on the regime of water reservoirs. In the recent decade, relevance of the research related to the impact of permafrost thaw on the state of small lakes in the Arctic has been growing. The influence of interannual fluctuations in air temperature and precipitation on the ionic composition of lakes has been statistically established for the contents of NO2, SO4, and NO3 ions. Active thermodenudation on the shores of these lakes increases water mineralization levels by an average of 42.8 % and changes the concentrations of major ions Na, Ca, Mg, K, PO4, and HCO3.

При апробации метода дешифрирования спутниковых радиолокационных снимков для детализации строения наледей и наледных ландшафтов использованы радарные снимки Sentinel-1. По результатам первичного анализа установлены диапазоны типичных сигналов обратного рассеяния в пределах наледной поляны и выбраны репрезентативные точки на снимке, характеризующие различные компоненты наледного ландшафта. По снимку Sentinel-2 предварительно устанавливался тип поверхности наледного ландшафта (лед, открытая вода, снежный покров, горная порода и др.). В ходе полевых работ в пределах ранее выбранных точек на радарном снимке изучалось вертикальное строение наледного ландшафта и особенности его поверхности. В результате были определены диапазоны обратного рассеяния радиосигнала для согласованной и перекрестной поляризаций, отражающие четыре типа строения наледного ландшафта. На основе радарных снимков было детализировано строение наледного тела: установлены участки речного стока под наледью, места разгрузки подземных вод. На конечном этапе определены площади наледей в конце зимы в долинах рек Самокит и Верхняя Нерюнгра на основе радарных снимков и нормализованного разностного снежного индекса, вычисленного по изображениям Sentinel-2, а также оценено расхождение значений площадей наледей.
Synthetic aperture radar (SAR) images Sentinel-1 were used to detail the structure of aufeis and characteristic features of aufeis landscapes in the valleys of Verkhnyaya Neyungri and Samokit rivers (southern Yakutia). Based on the results of preliminary image analysis, the ranges of typical backscatter signals within the ice glade were established, and representative points characterizing various components of the ice landscape were chosen. The type of surface of the aufeis landscape (ice, open water, snow cover, rock, etc.) was preliminarily diagnosed using Sentinel-2 images. During fieldwork, the vertical structure of the aufeis landscape and its surface were studied at the chosen test plots. As a result, the ranges of backscattering of the radio signal for co-polarization (VV) and cross-polarization (VH) modes characteristic of the four types of the aufeis landscape were determined. Based on SAR images, the structure of the aufeis body could be detailed: areas of river flow under the ice and places of groundwater discharge were identified. At the final stage, aufeis areas at the end of winter in the Samokit and Verkhnyaya Neryungri river valleys were determined based on Sentinel-1 SAR images and the normalized difference snow index (NDSI) calculated from Sentinel-2 images; the discrepancy between the obtained estimates was assessed.

Published: September 2024

Aim of the studyIn this study, a novel approach was undertaken, employing the concept of SSF isochrones in tandem with the time-area histogram (TAH) method as a fresh model for SSF estimation within catchments.Material and methodsLeveraging the subsurface travel time equation of hillslopes and GIS software, the spatial delineation of isochrones within the soil was accomplished. Furthermore, a methodology was introduced to compute the TAH of SSF. Subsequently, the subsurface hydrograph of the catchment was derived by convoluting the TAH of SSF with the infiltration hyetograph. To validate the findings, the subsurface hydrographs calculated using the geomorphologic instantaneous unit hydrograph (GIUH) model were juxtaposed with those from two catchments in northern Taiwan—Heng-Chi and San-Hsia.Results and conclusionsThe mean error in comparison with the SSF time-area model stood at 10.5%, affirming the robustness of the proposed approach.10.5%.
