Price Spread Analysis of Tezpur Litchi: A Case Study from Assam, India

Purpose: Being a geographical indication certified fruit, Tezpur litchi enjoys the consumer price difference of Indian Rupees 10 per litchi from the common varieties of litchi. Therefore, it is crucial to consider the different aspects of price spread which will make a way out to provide maximum benefit to the litchi growers. With this motive, this study aimed to analyse the price spread and identify the pattern of marketing channels that would be feasible and give profitable returns to the litchi growers. Research Method: The empirical data were collected from 218 samples that included four channel members i.e., litchi growers, pre-harvesting contractors, retailers and final consumers who are mainly involved in the marketing and consumption of Tezpur litchi. The data were analysed using specific formulas of price spread, the share of channel members in consumer’s price and marketing efficiency. Findings: Four patterns of marketing channels were identified for Tezpur litchi. Channel III which included litchi growers, retailers and final consumers was found the most feasible in the study area where 79% of litchi growers directly sell to retailers instead of pre-harvesting contractors. It was observed that price spread, the share of channel members in consumer’s price and marketing efficiency shared an inverse relationship with the number of mediators in the marketing channel. However, from the practical point of view, channel III is suggested to the litchi growers for a feasible and profitable return. Research Limitations: Exact information on the distribution of Tezpur Litchi to the other states and countries was not available. Therefore, the geographical scope of the study is limited to Assam. Originality/ Value: Understanding price spread is considered very important to cognise the efficiency of the marketing channels operating for a product. An effective marketing channel not only meets the demand of the consumers but also creates a favourable environment for the growers and intermediaries to increase production and add value to the product.

Ecological Implications of Dam and Barrage Construction in the Indian Himalayan Region: A Comprehensive Assessment

Dams and barrages are vital infrastructure for human needs such as hydroelectric power generation, irrigation, and water storage, but their construction has significant negative impacts on the biodiversity and riverine ecosystem of aquatic species. The Indian Himalayan Region (IHR) is known for its unique ecological and environmental significance. However, the construction of dams and barrages in this region has raised concerns regarding their ecological consequences. This paper aims to assess the ecological impacts of dam and barrage construction in the IHR. The construction of dams and barrages in the IHR has resulted in significant alterations to the natural flow patterns of rivers, leading to changes in hydrology, sediment transport, and water availability. These alterations have had profound effects on the aquatic ecosystems, affecting fish populations, riverine habitats, and biodiversity. Furthermore, the fragmentation of rivers caused by dam construction has disrupted migratory patterns of several species, thereby impacting their breeding and survival. This paper provides an overview of the ecological consequences of dam and barrage construction in the Indian Himalayan Region, highlighting the need for sustainable and environmentally sensitive approaches to infrastructure development in this ecologically fragile region. By considering the ecological implications and adopting appropriate mitigation measures, it is possible to strike a balance between meeting the energy and water demands of the region while safeguarding its unique and diverse ecosystems.

A MATHEMATICAL FRAMEWORK TO CHARACTERIZE COMPLEXITY ASSEMBLY IN FRACTAL RIVER NETWORKS

As a multi-scale system featuring fractal hierarchical branching structure, the quantitative characterization of natural river networks is of fundamental significance for the assessment of the hydrological and ecological issues. However, as already evidenced, the fractal behavior cannot be uniquely inverted by fractal dimension, which induces a challenge in accurately describing the arbitrary scale-invariance properties in natural river networks. In this work, as per fractal topography theory, an open mathematical framework for the description of arbitrary fractal river networks is proposed by clarifying the assembly mechanisms of complexity types (i.e. the original and behavioral complexities) in a river network. On this basis, a general algorithm for the characterization of complexities is developed, and the effects of the original and behavioral complexities on the structure of a river network are systematically explored. The results indicate that the original complexity determines the tortuosity and spatial coverage of a river network, and the behavioral complexity dominates the river patterns, heterogeneity, and scale-invariance properties. Our investigation lays a foundation for assessing and predicting accurately the effect on environments, ecology and humans from river networks.

Numerical investigation of a novel rhombohedral interconnector configuration for planar solid oxide fuel cells

ABSTRACT In this article, a novel rhombohedral interconnector with a staggered position is proposed by considering the influence of flow field variations on heat and mass transfer. The rhombohedral staggered interconnectors help to alter the fluid flow patterns in the flow channels, leading to an improvement in heat and mass transport behavior. It also assists to control the pressure distribution in the flow channels and improves the performance of anode-supported SOFCs. First, a comparison between existing experimental research and a traditional rectangular interconnector model is carried out to validate the physics of the SOFC functioning. Then the performance of a staggered-position rhombohedral interconnector is evaluated to that of a typical rectangular interconnector. To further understand the impact of flow rate on cell performance, parametric research with varied mass flow rates is conducted. The findings indicate that when compared to a conventional rectangular interconnector, the rhombohedral staggered interconnector design enhances the power density by 33.9%. With an increase in mass flow rate beyond a specified stoichiometric range, the performance decreases indicating an excessive supply of reactants. Using the proposed staggered rhombohedral interconnector configuration, the SOFC can be designed to operate optimally.

Morphohydraulic of a dam-impacted large river: The São Francisco River, Brazil

Many studies have highlighted dam impacts in the reduction of the transmission of nutrient loads and suspended sediments downstream, increasing coastal erosion (sediment budget) and water residence time, beyond modifying the channel planform on a reach scale. However, the morphohydraulic changes, which are induced by flow regulation, have been little explored. This study has sought to analyze temporal changes in the at-a-station hydraulic geometry from 9 cross-sections along the São Francisco River, comparing the pre and post-dam periods. In addition to that, it was also sought to compare our results with other tropical river systems and assess the relationships of morphohydraulic parameters with channel patterns and functional trends. We have used field data collected by the National Water Agency and the Geological Survey of Brazil covering the middle, lower-middle, and lower courses of the São Francisco River. Potential functions were extracted using the least squares fit method. We have applied the Mann-Whitney non-parametric statistical test to assess any dataset changes. Finally, we have analyzed the data through the ternary diagram. Our results have demonstrated that the São Francisco River has high bank stability and variations in flow are mainly accommodated by changes both in depth and flow velocity. We found changes in the sensitivity of width, depth, and velocity in the post-dam period that imply high mobility of the cross-sections in the ternary diagram. Changes in land use patterns are potentially associated with these observed changes. Despite the São Francisco banks being stable in the analyzed cross-sections, the sensitivity of the channel width increased in the post-dam period. Differences were observed between the response patterns in the post-dam period in the physiographic provinces of the São Francisco River. However, the increase in width sensitivity predominates, with few exceptions. Hydraulic geometry analyses have proved to be essential for the characterization of the functional dynamics of river systems and allowing inferences about sediment transport conditions, flow stage, and channel stability.

Was the termination of the Jizera River meandering during the Late Holocene caused by anthropogenic or climatic forcing?

AbstractThe Jizera River in Czechia is a typical mid‐sized Central European watercourse. Its floodplain shows a morphological contrast between the laterally stable low‐sinuous current channel and preserved palaeomeanders. The aim of this paper was to date and explain the obvious metamorphosis of the channel pattern from meandering to low‐sinuous. We analysed the morphology of the lower river reach using a digital terrain model (DTM) and historical maps from the 1840s. Furthermore, the floodplain architecture was described based on the DTM, geophysical imaging (ground penetrating radar, GPR), sediment lithology and anthropogenic contamination using geochemical proxies, and optically stimulated luminescence (OSL) dating. The geochemical proxies were processed using log‐ratio methods from the compositional data analysis toolbox. According to our results the Jizera River showed signs of systematic lateral floodplain reworking during the Late Holocene with only minor aggradation, although parts of the catchment are covered by easily erodible loess. Interestingly, vertical aggradation did not show a significant increase during the last millennium. In the main study area, this limited vertical aggradation resulted in the preservation of palaeomeander fragments and palaeochannel belts with 100–200 m mean width in the 300–600 m wide floodplain, which are recognisable in the topography and in subsurface GPR imaging. This channel meandering took place between around 4 and 1.2 ka, and the transition towards the laterally stable modern channel with low sinuosity occurred around 1.2 ka. This timing indicates a climatic rather than anthropogenic impact, which was rather weak around that time. One likely cause for this transition was the influx of material from ravines incised into the sandstone valley edges during past climatic extremes. Subsequently, the re‐establishment of a meandering pattern was possibly prevented by a combination of low fluvial activity and the construction of weirs that reduced stream power.

River pattern discriminant method based on Rough Set theory

Study regionThe Yellow River located in the north of China, the most hyper-concentrated sediment-laden rivers in the world, is featured by complicated spatiotemporal variation of river patterns. Study focusRiver patterns contribute to comprehending the spatial morphological evolution of rivers associated with hydrological processes. However, it is still a challenge to effectively discriminate different river patterns due to the dynamics and variability of rivers. A solution is proposed to discriminate river patterns based on Rough Set theory via a holistic synthesis of multi-dimensional morphological information. First, a hierarchical structure integrating the boundary and the interior was suggested to maximally describe the morphological feature of river patterns. Rough Set theory was applied to select the main feature factors from multiple geometric indexes and landscape pattern indexes. Finally, river pattern discriminant rules were generated based on the reduced feature subsets. New hydrological insights for the regionResults demonstrate that 81 discriminant rules efficiently express the morphological feature of four river patterns. Compared with several competitive machine learning methods, river pattern discriminant rules display good performance, with the advantages of interpretability, simple modelling, and fewer training samples. Furthermore, the established discriminant rules of river patterns have achieved an accuracy of 98.63% in the application of the Lower Yellow River, which is expected to analyse the spatiotemporal evolution and geomorphological processes of different river patterns.

MmWave extra-large-scale MIMO based active user detection and channel estimation for high-speed railway communications

The current High-Speed Railway (HSR) communications increasingly fail to satisfy the massive access services of numerous user equipment brought by the increasing number of people traveling by HSRs. To this end, this paper investigates millimeter-Wave (mmWave) extra-large scale (XL)-MIMO-based massive Internet-of-Things (IoT) access in near-field HSR communications, and proposes a block simultaneous orthogonal matching pursuit (B-SOMP)-based Active User Detection (AUD) and Channel Estimation (CE) scheme by exploiting the spatial block sparsity of the XL-MIMO-based massive access channels. Specifically, we first model the uplink mmWave XL-MIMO channels, which exhibit the near-field propagation characteristics of electromagnetic signals and the spatial non-stationarity of mmWave XL-MIMO arrays. By exploiting the spatial block sparsity and common frequency-domain sparsity pattern of massive access channels, the joint AUD and CE problem can be then formulated as a Multiple Measurement Vectors Compressive Sensing (MMV-CS) problem. Based on the designed sensing matrix, a B-SOMP algorithm is proposed to achieve joint AUD and CE. Finally, simulation results show that the proposed solution can obtain a better AUD and CE performance than the conventional CS-based scheme for massive IoT access in near-field HSR communications.

Hydrology and Seasonality Shape the Coupling of Dissolved Hg and Methyl‐Hg With DOC in Boreal Rivers in Northern Québec

AbstractCo‐loading of mercury (Hg) with dissolved organic carbon (DOC) is a key driver of the observed spatial and temporal Hg patterns among aquatic ecosystems. Their strong biogeochemical coupling has spurred the use of DOC as a predictor of Hg concentrations and exports in boreal regions where sampling logistics for Hg are costly and complex. Yet relationships between Hg and methylmercury (MeHg) with DOC have recently been shown to be highly variable in terms of slope and strength, suggesting that mechanisms other than co‐transport along the land‐water continuum may drive the relationship between Hg and DOC across landscapes. In this study, we explore the relationship between Hg and MeHg with DOC across 18 boreal rivers collectively draining over 350,000 km2 of the eastern James Bay territory (Québec), comprising watersheds with a wide range of vegetation, water residence time and riverine DOC concentrations and optical properties. Our results show that although a large portion of the variation in Hg and MeHg is explained by concentrations of DOC, Hg‐DOC and MeHg‐DOC relationships and ratios vary greatly both spatially and temporally. We show that ratios and strength of the coupling can be predicted from system hydrology, with declines in Hg:DOC and increase in MeHg:DOC ratios and stronger coupling during the seasonal progression to warmer temperatures, higher water evaporation, and longer residence time. Our study highlights the role of seasonal hydrology and biogeochemical processing in governing Hg, MeHg and DOC patterns in boreal rivers.

A structure metric for quantitative assessment of fracture surfaces in 3D conceived based on confocal laser scanning microscopy data

Assessment of fracture surfaces typically involves the identification of qualitative features such as dimples, grain facets, and river patterns to determine type of fracture. The present study formulates a measure termed Real-to-Projected Area (RPA) ratio/metric to quantitatively assess fracture surfaces. Fractures surfaces of several metallic alloys tested monotonically and in fatigue to fracture including three Mg alloys, a Ti alloy in two conditions, and a Ni-based superalloy were observed using confocal laser scanning microscopy in 3D and quantitatively assessed using the metric. The metric successfully separated fracture surfaces obtained after fatigue testing from those obtained after monotonic tension testing. Specifically, the values of the metric were found to be in the range of 40–80 pct for fatigue fracture, while 90–140 pct for monotonic tension fracture. As a result, the metric can be used to distinguish between fracture in fatigue and fracture in monotonic tension when fracture types / loading modes are unknown. Moreover, the metric is sensitive to ductility of tested alloys as well as any presence of critical defects in the microstructure responsible for rapid fracture such as intermetallic inclusions. An added utility of the metric is also to identify outliers in the data such as invalid mechanical tests. • Real-to-Projected Area (RPA) ratio/metric is defined to quantitatively assess fracture surfaces. • Fracture surfaces of several alloys are observed using confocal laser scanning microscopy and quantified using the metric. • The metric can successfully separate fatigue fracture surfaces from monotonic tension fracture surfaces. • The metric is sensitive to ductility of tested alloys and defects in the microstructure such as intermetallic inclusions. • The metric can identify outliers in testing to fracture data such as invalid mechanical tests.

Behavior and Marketing Analysis of Pepper (Piper nigrum L.): A Comparative Study of Farmers, Trading Districts and Retailers in Southeast Sulawesi, Indonesia

Inefficient marketing and low production are the main obstacles in the selling of pepper and they also cause a low bargaining position for farmers in the market. Therefore, this study aims to determine the market behavior activities carried out to determine prices, as well as analyze marketing channels, profits received by participants and efficiency. Samples used in this study were 27 farmers, 4 trading districts, and 3 respondent retailers. The qualitative analysis was used to analyze the pattern of channels, the functions performed by associated agencies and the market behavior of the pepper commodity. Quantitative analysis was also carried out to evaluate the marketing margins, costs incurred by traders, profits received and efficiency. The results show that the selling price of pepper was determined by the merchant, with different payment systems including cash, initial deposit, and balance through oral cooperation in the form of an agreement on a place of sales, followed by the provision of capital to farmers. In the marketing process, 4 patterns of channels were formed, which include local markets and others outside the regency, and their efficiencies were above 50%. These results show that government need to provide pepper markets outside the province to improve the welfare of farmers and ensure they don't depend only on the local marketplace during harvest.

Lagrangian Numerical Simulation of Proppant Transport in Channel Fracturing

This paper focuses on the numerical simulation of particle (“proppant”) transport in channel fracturing, in which fiber-proppant fluid is pumped intermittently into hydraulic fractures, alternated with clean fluid pulses. The pulsed pumping protocol leads to heterogeneous/channelized proppant distribution in fractures, generating open flow channels with high conductivity. To understand the evolution of the channelized proppant distribution, we develop an efficient pseudo-3D multiphase particle-in-cell (P3D MP-PIC) method to simulate the proppant transport during the pumping process. Compared with the Eulerian-Eulerian (EE) models, the MP-PIC approach has higher accuracy in modeling particle-fluid and particle-particle interactions by tracing the particles in a Lagrangian fashion. Compared with the computational fluid dynamics-discrete element method (CFD-DEM), the MP-PIC method is more computationally efficient due to a parcel feature and the fast calculation of particle forces. Reduced from the 3D MP-PIC method, the P3D MP-PIC method has better computational efficiency and flexibility to couple with other subsurface processes (e.g., fracture propagation and fluid leakoff) while also achieving sufficient accuracy for engineering purposes. Due to the Eulerian-Lagrangian (EL) nature, the P3D MP-PIC method can track the trajectories of the fiber-proppant clusters whose effective viscosity and the settling velocity are determined based on the laboratory results. With an accurate description of fluid and particle dynamics, this work reveals the critical physical mechanisms of the proppant transport in channel fracturing: stable displacement and Saffman-Taylor (ST) instability. The alternate occurrence of these two mechanisms gives rise to the channelized proppant distribution. To investigate the influential factors of the channel patterns, we conduct parametric studies on the operational parameters, including injection rate, fiber concentration, and pulsing mode. The effect of fracture propagation and gravitational settling is also discussed in detail.

Evaluation of river longitudinal connectivity based on landscape pattern and its application in the middle and lower reaches of the Yellow River, China.

River connectivity plays an essential role in maintaining the health and stability of river basin ecosystems. It is of great significance to protect river ecosystems to clarify the effect of water conservancy project construction and operation on river hydrological connectivity. The longitudinal connectivity is affected by the landscape patterns of river, such as the convergence and dispersion of the mid-channel bars and the river areas. This study aims to analyze the impacts of construction and regulation of Xiaolangdi Dam on the connectivity of the middle and lower reaches of the Yellow River from the perspective of landscape pattern. An improved longitudinal river connectivity evaluation method was proposed by accounting for the influence of the landscape pattern represented by mid-channel bars based on barrier coefficient method, and then was applied to analyze the connectivity pre- and post-dam construction. The results show that the amplitude and frequency of the oscillation of the river were greatly reduced and tended to be stable. The aggregation degree of mid-channel bars was reduced, and the distribution of mid-channel bars was more dispersed. The river longitudinal connectivity before and after the construction of the Xiaolangdi Dam were 1.35 and 1.50 respectively, indicating an increased river longitudinal connectivity. Overall, there are differences in connectivity before and after Xiaolangdi Dam construction, and connectivity fluctuates after dam construction. Because of the dam regulation of water and sediment, the river connectivity during the flood season increased significantly, and was greater than that before and after the flood season. The longitudinal connectivity evaluation method established in this study is accurate and efficient, and provides an intuitive and reliable new method for quantitatively analyzing the changing laws and characteristics of river connectivity.

Quasi-equilibrium channel metamorphosis in planform of a subtropical river in India in post-dam period

A basic fluvio-dynamics process in the sediment-energy fluxes is channel meandering and braiding. The construction of dams and barrages has primarily altered the meandering and braiding patterns of the world's large rivers. To this end, the present study aims to analyze post-dam planform characteristics of the Damodar River, a subtropical river in India, based on the analysis of meander geometry, Mueller’s sinuosity index, braiding index, channel count index, and channel length index during the last 50 years (1970–2020) using topographical maps and satellite images. The study also intends to forecast channel meandering and braiding characteristics for 2030 and 2050 using an Artificial Neural Network (ANN) model. The study results show that between 1970 and 2020, the standard sinuosity index (SSI) showed a larger tendency to meander in the middle of the river than the upper and lower courses owing to hydraulic control, while the lower and upper courses were controlled by topographic factors. Similarly, channel braiding indices (BI*, BI, and Pt) exhibit swelling in the upper and middle courses followed by a gradual fall in the lower stretch. The building of dams, the presence of lineaments, faults, and other anthropogenic controls primarily regulate the physical planform characteristics of the river. Regarding allometry, the river's upper segments exhibit both positive and negative allometry in certain combinations, whereas the lower segments primarily exhibit negative allometry. The study demonstrates that over the past 50 years, overall channel meandering has slightly decreased while braiding has slightly increased over time, indicating a quasi-equilibrium channel metamorphosis. However, the prediction with higher accuracy (80–95 %) shows that the river meandering and braiding (BI* and BI) will increase in the short run (2030), and decrease in the long (2050). The study findings may be helpful for the various planners and stakeholders involved in the development of the river basin.

Deep learning-based multimode fiber imaging in multispectral and multipolarimetric channels

Multimode optical fiber (MMF) imaging is an emerging fiber imaging technology that has been developed during the last decade. In this work, we demonstrate deep-learning-based MMF imaging for multispectral and multipolarimetric channels. Specifically, by controlling the wavelength and polarization of the incident light of MMF, different spectral and polarization channels are constructed. We conduct MMF transmissive imaging experiments and record a large number of object-speckle pairs in each channel for neural network training. A neural network is trained to simultaneously reconstruct the intensity and classify the channel of objects in eight spectral or nine polarimetric channels. The average structural similarity (SSIM) of the image reconstruction in each spectral and polarimetric channel exceeded 0.9 with the accuracy of the channel classification exceeding 99.9%. By superimposing speckle patterns of different spectral channels, a new dataset is constructed for training, and the reconstruction of images containing multiwavelength information is also tested in eight spectral channels. Our findings have the potential to extend the application of MMF imaging with spectral and polarimetric information
