Geological and Geochemical Responses to Productivity of CBM Wells in the Baiyang River Block of the Southern Junggar Basin, China

The southern Junggar Basin, Xinjiang, has abundant coalbed methane (CBM) resources. Currently, the Baiyang River development pilot test area (BYR block for short) in the Fukang east block has achieved large-scale CBM development, but the productivity characteristics and its controlling factor are still unclear. Based on the field production data of the BYR block and experimental tests, this paper summarizes the gas and water production characteristics and presents the analysis results of the geological and geochemical responses to the productivity of CBM wells. The productivity of CBM wells in the BYR block was generally characterized as medium-to-low yield. The productivity was jointly controlled by the burial depth, structure condition, thickness and number of co-production coal seams, and hydrogeological conditions. The gas production first increased and then decreased with the increase in the burial depth of the coal seam, and a burial depth between 750 and 1000 m was the most beneficial to increasing the gas production due to the good gas preservation conditions and suitable permeability and stress conditions. The total thickness of the co-production coal seams had a positive effect on the productivity of gas wells, but the productivity was also affected by the number of co-production coal seams and interlayer interference. In the BYR block, the co-production of the nos. 41 and 42 coal seams was the most favorable combination form for CBM drainage. The productivity of CBM wells had a good response to the Na+, K+ and HCO3− concentrations but a poor response to δD-H2O and δ18O-H2O. Based on the concentrations of the main ions and TDSs of the coal seam water, a productivity response index δ* was established, and there was a good positive correlation between the productivity and δ*.
Influence of laser-induced Au-plasma plume collision on the efficiency of x-ray radiations and the energy-transport process relevant to ICF

Experiments and simulations have been carried out to study the colliding process by two lasers irradiating a gold half-hohlraum. Via analyzing the evolutionary x-ray images, radiation fluxes and self-emission spectrum of tracers, influence on the x-ray conversion efficiency and the local plasma temperature Te,i from two gold-plasma plumes have been investigated deeply, which is similar as the configuration in Inertial Confinement Fusion (ICF). Experimental results confirm a region with high electron and ion temperatures Te,i are induced, satisfying the strong collision condition of λi<ΔL , where λ i and ΔL are respectively the ion mean-free path and the gradient length of Te . It leads to almost 30% increasing of M-band component compared to that from a single laser-irradiation case. Meanwhile ion temperature in this region increases more rapidly than electrons, reaching about Ti≈(16±4) keV ( Te≈(2±0.2) keV). Thus, our studies provide the experimental evidence of quantitative x-ray enhancement and a non-equilibrium evolution simultaneously due to the plasma collision for the first time. Besides, two-dimensional simulation results reveal that this process can not be precisely described by the traditional shock-heating model by dissipating the shock energy only to ions. But by distributing the viscous heating between both electrons and ions as theoretically discussed by Miller (2020 Comput. Fluids 210 104672), numerical results can match experiments better. This discovery will be of great importance to improve the precision of prediction for ICF.
Changes in the Active Drainage Network and Their Impact on the Hydrological Response and Flood Risk Management Process: A Case Study for a Flysch Mountain Catchment

The active drainage network (ADN), as a dynamic component of a catchment, plays an important role in a catchment’s functioning. Changes in the ADN are the most noticeable during extreme hydro-meteorological events, and they result from, among others, the incorporation of man-origin incisions into the ADN. Knowledge of the parameters of the “real” ADN is a key element in the field of catchment hydrology because the ADN affects the intensity of hydro-, geomorpho-, and biological processes. The goals of this study are to assess (1) the changes in the ADN during extreme hydro-meteorological events (with special attention paid to the human-induced impact on the ADN transformation) and (2) the consequences of the ADN changes on the hydrological response of a catchment and their impact on the flood hazard/risk management processes. The study was performed in a mountain catchment, prone to flash flood occurrences. The ADN was reconstructed with the use of ALS-LiDAR data using GIS tools, and the hydrological response was evaluated by using SCS-CN and GIUH models. The results revealed that the ADN functioning during heavy rainfalls is three to four times denser than the natural-origin river drainage network (RDN) (11.4 km·km−2 vs. 2.9 km·km−2), and the RDN is significantly modified by human-origin elements (e.g., roads, ditches, furrows, etc.—they constitute ca. 1/3 of the ADN). Moreover, significant structural changes in the ADN have occurred, which were confirmed by the Hortonians’ type of analysis. The changes in the ADN have affected the hydrological response of the catchment (predominantly an increase in the peak flow—up to 7%) and the dimensions of the 1% probable flood hazard zone (increase of ca. 5%). It may be concluded that significant changes in the ADN, in the catchment studied, had a moderate impact on the changes in the flood hazard level. The results give a new insight into the flood hazard/risk assessment processes in a small flysch mountain catchment.
Seasonal variation in mineral concentrations of four marine fish species retained by fishers in Vanga and Msambweni, Kenya

Marine fish is a rich source of minerals in the diet of humans, but seasonal variation in fish mineral concentrations is relatively unstudied. We investigated seasonal mineral concentrations among four marine fish species retained by small scale fishers in Msambweni and Vanga fishing villages in Kenya. The fish species were Siganus sutor (rabbitfish) in Msambweni and Decapterus macarellus (mackerel scad), Sphraena forsteri (bigeye barracuda) and Sphyraena obtusata (obtuse barracuda) in Vanga. Mineral concentrations were quantified in 120 fish specimens (60/season) and their mineral supplementation potential evaluated. The concentrations of Potassium (K), Magnesium (Mg), Zinc (Zn), Iron (Fe) and Iodine (I) were determined using Inductively Coupled Plasma Optical Emission Spectrometry. K, Mg, Zn and I levels in fish samples varied between seasons with higher concentrations during the wet and cool southeast monsoon (SEM) season (April to October). However, Fe concentration was significantly higher during the dry and warm northeast monsoon (NEM) (November to March). S. fosteri recorded the highest concentrations of Mg (72.29 mg/100g in SEM) and Fe (3.63 mg/100g in NEM). S. sutor was the richest source of K (410.21 mg/100g in SEM). These two species also recorded the highest concentration of I (57.6 μg/100g in SEM) while D. macarellus had the highest Zn concentration (5.84 mg/100g in SEM). Mineral concentrations were dependent on fish species as well as season, influencing the mineral intake in Msambweni and Vanga villages.
Biomass Pyrolysis-Derived Biochar: A Versatile Precursor for Graphene Synthesis

Graphene, a two-dimensional carbon allotrope with a honeycomb structure, has emerged as a material of immense interest in diverse scientific and technical domains. It is mainly produced from graphite by mechanical, chemical and electrochemical exfoliation. As renewable energy and source utilization increase, including bioenergy from forest and woody residues, processed, among other methods, by pyrolysis treatment, it can be expected that biochar production will increase too. Thus, its useful applications, particularly in obtaining high-added-value products, need to be fully explored. This study aims at presenting a comprehensive analysis derived from experimental data, offering insights into the potential of biomass pyrolysis-derived biochar as a versatile precursor for the controlled synthesis of graphene and its derivatives. This approach comprehended the highest energy output and lowest negative environmental footprint, including the minimization of both toxic gas emissions during processing and heavy metals’ presence in the feedstock, toward obtaining biochar suitable to be modified, employing the Hummers and intercalation with persulfate salts methods, aiming at deriving graphene-like materials. Material characterization has revealed that besides morphology and structural features of the original wooden biomass, graphitized structures are present as well, which is proven clearly by Raman and XPS analyses. Electrochemical tests revealed higher conductivity in modified samples, implying their graphene-like nature.
Reacting to a Large-Scale UNK-UNK during Its Initial Onset: Fast Response and Retrospective Sensemaking in South Korea

This study addresses how a nation may cope with a large unknow-unknown event with looming uncertainty. We focus on Korea’s response to the onslaught of COVID-19. Although Korea’s response was fast and immediate, it was also incremental and disjointed. This study aims to provide a structured understanding of the confusing state of early responses. We adopt the theory-building approach based on case studies and use newspaper articles and government press releases as the primary sources of data. We develop a grounded theoretical model as evidence and use the enactment theory to explain the underlying empirical and theoretical dynamics.
Excess River Sedimentation at Bridges in the Raya Graben (Northern Ethiopia)

This study investigates the temporal variability and effects of bio‐climatic factors and bridges on local hydro‐geomorphic conditions that cause excess sedimentation and flood hazard in ephemeral rivers of the Raya graben (northern Ethiopia). Normalized difference vegetation index (NDVI) was analyzed using Landsat imageries of 1972, 1986, 2000, 2005, 2010, and 2014. Daily rainfall data of three meteorological stations were considered to analyze the temporal trends and return time intervals of rainfall intensity in 24 h. Stream‐bed gradient and bed material grain size were measured in 20 river reaches. Results show that the maximum NDVI values were recorded in the time interval from 2000 to 2014. Nevertheless, during this decade, the study bridges experienced the largest excess sedimentation, in some bridges up to 1·6 m. Different factors to account for it are discussed as no evidence of rainfall pattern, accountable for an increase in sediment delivery from the headwaters, is found. The field data show that channel narrowing at bridges is the main cause of thick upstream sedimentation and of increasing frequency of overbank flows during the last 15 years. A simple hydraulic approach is presented to explain the variability of sediment deposition at bridges and change in bed material grain size between the main stem and the reach right upstream of the bridge.

Turkish Adaptation and Validation of the European Cyberbullying Intervention Project Questionnaire (ECIPQ)

Over the last two decades, cyberbullying has gained increasing attention from the research community as the phenomenon has become a public health issue affecting children, adolescents, and young adults. Although several instruments assess cyberbullying worldwide, many still need to be adequately validated in different languages, countries, and cultures. The European Cyberbullying Intervention Project Questionnaire (ECIPQ) is one instrument that aims to measure two dimensions of cyberbullying: cyber-victimization and cyber-aggression. Although the instrument has been translated into various languages and validated in several European and non-European countries, adaptation and validation studies have yet to be conducted in Turkish culture. This study aimed to adapt the ECIPQ into Turkish and investigate the psychometric quality of the instrument in the Turkish population. A total sample of 632 college students participated in the study. The results showed that the Turkish version of the ECIPQ had sufficient internal consistency. The confirmatory factor analysis supported the two-factor structure of the ECIPQ. The ECIPQ showed adequate convergent validity, as evidenced by the positive correlation between the cyberbullying and aggression scores and the negative correlation between cyberbullying and self-esteem scores. In conclusion, the ECIPQ can be considered as a psychometrically sound measure to assess Turkish college students' perceived cyber-aggression and cyber-victimization levels.
The impact of westernisation on the purchase intention of cruelty-free products: a study based on the Sri Lankan cosmetic market

PurposeA surge in demand for ethical products, including cruelty-free products, has been well documented in recent years, with direct ramifications for businesses. This trend towards ethical consumption seemed to be swiftly replicated in Eastern countries, especially in South Asian nations, as a result of westernisation. Based on the theory of planned behaviour and the concept of the attitude-behaviour gap, this study aims to investigate the impact of westernisation on the purchase intention of cruelty-free cosmetic products.Design/methodology/approachA positivist research paradigm was utilised in this study. Accordingly, an online self-administered questionnaire was shared among 242 consumers of cosmetic products in Sri Lanka in order to collect responses. The statistical techniques of correlation analysis, the Sobel test and moderator regression analysis have been utilised in this study.FindingsIt was found that there seems to be a positive impact of westernisation and the cruelty-free purchase intention of consumers. Moreover, consumer empowerment appears to mediate this relationship, while the attitude behaviour gap tends to further impact the relationship between consumer empowerment and the purchase intention of cruelty-free products.Originality/valueThis study seems to shed light upon the impact of westernisation on the purchase intention of consumers, especially from an ethical dimension and this study is likely to extend existing studies which have focussed on consumer empowerment, attitude-behaviour gap as well as the theory of planned behaviour, especially in the context of South Asia, where there seems to be a dearth of such investigations. Moreover, this study has attempted to contextualise the construct of “Westernisation” to the South Asian region in line with the tone set by an editorial article Dewasiri et al. (2021).
Impact of Bank Concentration on Volatility – The Case of European Economies

The goal of this paper is to investigate the impact of concentration in the banking sector on the economic and financial stability. Having in mind that the European countries are predominantly bank-centered, we begin with the assumption that too much power concentrated in a small number of financial institutions could have a significant impact on the entire economy. Therefore, our aim is to examine the impact of concentration in the banking sector on the stability of both the financial system and the economy. For the purpose of the study, we have created a sample of 44 European countries, with data covering the period 2000-2021. The methodology involves two econometric techniques: logistic regression and the Generalized Method of Moments procedure to address the problem of possible endogeneity of the data. Using a set of independent variables representing the level of concentration and competition, as well as a set of controlling variables, the results show that the higher concentration of assets among the largest banks has a negative impact on economic stability, while the impact on financial stability is undetermined. The remaining variables show that the countries with higher growth rates and higher capital investments exhibit more stable growth, while the impact of inflation is generally negative.
Waveform correlation detection methods applied to the 2003-2004 seismic swarm in the Marysville volcanic province of central Utah

Earthquake swarms are defined as clusters of events that occur closely in space and time without the presence of an outstanding main shock. Swarms are especially common within the seismically active region of the Intermountain West, monitored by the University of Utah Seismograph Stations (UUSS). The source mechanism of swarms is not well understood, although previous work suggests that they are sometimes induced by the propagation of hydrothermal or magmatic fluids. To better understand the spatial and temporal characteristics of seismic swarms in Utah, waveform correlation methods were used to detect small events in a swarm sequence that were missed in routine UUSS earthquake cataloging. The main sequence of the analyzed swarm lasted from 29 Nov through 4 Dec 2003, and occurred near the Marysvale volcanic province in central Utah. Utilizing nine single-component and two three-component UUSS short-period seismic stations, at distances of 29-161 km from the swarm source, a single waveform template detector was run against continuous seismic data from 2003-2004. This method detected 453 new events, increasing the original UUSS catalog of 36 swarm events by a factor of about 13. A total of 126 of these detections were detected at four or more stations and are likely to be locatable. The single template method was tested for robustness by comparing results from multiple single event templates and by comparing the single event template to a stack template and a two-dimensional empirical subspace. Within the uncertainty bounds, no technique was superior when applied to all the stations. ABSTRACT. Ill. Ill LIST OF TABLES.v LIST OF FIGURES. vl ACKNOWLEDGMENTS.vlll Chapters
Design and Improvement of Dewatering System Implemented for Biogas Slurry

The project addresses the pressing need for organic fertilizers in Nepal and explores an eco-friendly alternative to chemical fertilizers. By dewatering biogas residue, this research contributes to sustainable agriculture practices. The project's methodology involved a combination of research, literature recommendations, and guidance from experienced supervisors. SolidWorks was utilized for the design phase, while ANSYS facilitated simulation works. Subsequently, the testing of the dewatering machine was conducted. The biogas slurry used for testing and sun-drying was sourced from a prototype 1m3 capacity biogas plant. The machine's performance was evaluated at various operating speeds, with 8 rpm identified as the most efficient. Notable outcomes included a liquid yield of 52.51%, an extraction efficiency of 79.11%, and extraction losses amounting to 22.80%. To enhance the quality of the organic fertilizer, the slurry sample underwent sun-drying for different durations: 24, 48, and 72 hours. Nutrient concentrations (TS, N, P, K) were analyzed, that came with the 48-hour sun-drying period proving to be the most effective in reducing Total Solid contents. Comparatively, pre-treating the slurry sample for 24 and 48 hours prior to testing in the dewatering machine allowed for an assessment of the machine's efficiency, offering valuable insights to be contrasted with the sun-drying process. This research paves the way for a greener, more efficient method of dewatering biogas slurry, aligning with Nepal's agricultural and environmental sustainability goals.
A Comparative Analysis of Choorna and Bhavitha Choorna of Flower Buds of Japa (Hibiscus rosa-sinensis Linn.) through High-performance Thin-layer Chromatography

Introduction:High-performance thin-layer chromatography (HPTLC) is nowadays adopted by the major pharmacopoeias of the world for analysis of herbal drugs and preparations. The current use is generally limited to the visual observation of the fingerprints for identification and detection of adulterations and falsifications. It makes sense to use HPTLC to expand chromatographic fingerprints to identify the main active ingredients in medicinal plants. Compared to thin layer chromatography, the separation and resolution are significantly superior, and the outcomes are far more consistent and repeatable. Materials and Methods: Japakusuma mukula (flower buds of Japa) which is botanically identified as Hibiscus rosasinensis Linn. contains various phytoconstituents such as flavonoids, terpenoids, steroids, polysaccharides, alkaloids, amino acids, lipids, sesquiterpene, quinones, and naphthalene groups. HPTLC fingerprinting profile of choorna (powder) and bhavitha choorna (triturated powder) of flower buds of Hibiscus rosa-sinensis Linn. is demonstrated in methanolic extract in this study and bands are analyzed at 254 nm and 366 nm using CAMAG Linomat V Automatic Sample Spotter. The peaks and area are compared. Results and Conclusion: Similarity in the peak areas even in different Max Rf values, it could be inferred that the phytoconstituent obtained in both conditions will be having similarity. Since the bhavitha choorna possess, the greater number of large value peak areas in both the wavelength of visualization, it is clear that bhavitha choorna is more potent in comparison with choorna.
Depositional processes in the distal part of a large alluvial fan's feeder channel in Himalayan foothills, India

This paper presents results of detailed facies and architectural element analyses of the sedimentary fill of the Ranibag valley in the Himalayan foothills of north‐western India. Forming a buffer zone between the source and sink of the Ganga foreland basin's Gola alluvial fan, the Ranibag valley is filled with coarse gravels comprising five distinct facies. These are clast‐supported massive gravel, horizontal‐bedded gravel, crudely bedded gravel, sandy gravel and matrix‐supported disorganized gravel facies. The specific assemblages and sequences of these facies, defined by fifth‐ and fourth‐order bounding surfaces, belong to mutually associated channel (CH) and gravel bar and bedform (GB) architectural elements. Both the elements have accreted only during floods by combined fluvial and debris‐flow processes, but dominantly by the fluvial processes under conditions of high water‐to‐sediment ratio. Depositional processes in the valley are akin to those of the proximal alluvial fans of the Ganga Basin. Nonetheless, voluminous alluviation of coarser gravels in this extreme distal feeder channel valley has affected the fan processes downstream. It reduced the sediment budget and thus increased water‐to‐sediment ratio downstream to favour fluvial processes on the Gola fan. Copyright © 2016 John Wiley & Sons, Ltd.
A Temporal Approach to Defining Place Types based on User-Contributed Geosocial Content

Author(s): McKenzie, Grant | Advisor(s): Janowicz, Krzysztof; Raubal, Martin | Abstract: Place is one of the foundational concepts on which the field of Geography has been built. Traditionally, GIScience research into place has been approached from a spatial perspective. While space is an integral feature of place, it represents only a single dimension (or a combination of three dimensions to be exact), in the complex, multidimensional concept that is place. Though existing research has shown that both spatial and thematic dimensions are valuable, time has historically been under-utilized in its ability to describe and define places and their types. The recent availability and access to user-generated geosocial content has allowed for a much deeper investigation of the temporal dimension of place. Multi-resolution temporal signatures are constructed based on these data permitting both place instances and place types to be compared through a robust set of (dis)similarity measures. The primary contribution of this work lies in demonstrating how places are defined through a better understanding of temporal user behavior. Furthermore, the results of this research present the argument that the temporal dimension is the most indicative placial dimension for classifying places by type.
