    High-resolution remote-sensing images can be used in human activity analysis and criminal activity monitoring, especially in sparsely populated zones. In this paper, we explore the applicability of China’s Gaofen satellite images in the land cover classification of Xinjiang, China. First of all, the features of spectral reflectance and a normalized radar cross section (NRCS) for different types of land covers were analyzed. Moreover, the seasonal variation of the NRCS in SAR (Synthetic Aperture Radar) images for the study area, Dunkuotan Village of Yuli County, China, was demonstrated by the GEE (Google Earth Engine) platform accordingly. Finally, the CART (classification and regression trees) algorithm of a DT (decision tree) was applied to investigate the classification of land cover in the western area of China when both optical and SAR images were employed. An overall classification accuracy of 83.15% with a kappa coefficient of 0.803 was observed by using GF-2/GF-3 images (2017–2021) in the study area. The DT-based classification procedure proposed in this investigation proved that Gaofen series remote-sensing images can be engaged to effectively promote the routine workflow of the administrative department

    Agricultural development has long been the biggest challenge faced by governments or rulers of many countries and regions, be it in the past or at present. It affects the various political, social and economic development aspects of a country or region. Based on various long-term and short-term social needs, the authorities have attempted to find a suitable balance, searching constantly for feasible methods to manage agriculture, in the hope of harmonising the interests of peasant households, consumers and the ruling class through administrative measures. This has resulted in continuous adjustments in agricultural policies and effectively affected the development of agriculture as well as the well-being of farmers and the general public.As an entrepot, Hong Kong had very little arable land. The number of people engaged in farming, either directly or indirectly, was dwarfed by the consumer population. How to provide the large population with sufficient food, enabling it to be a driver behind economic development? This question became an important political issue for the Hong Kong colonial government for more than 100 years. Sino-British relations fluctuated considerably after the Second World War and this made agricultural development a thorny problem for the colonial government. In the course of studying 60 years of agricultural development, the most striking impression is that the Hong Kong colonial government was totally involved in agricultural production in the New Territories through the systematic promotion of the cooperative movement involving production, transport and marketing. This had made contribution to Hong Kong's unique political and social environment.This thesis reconstructs the agricultural history of Hong Kong in the post-war period. It explores the profound influence that the Agricultural Cooperative Movement has on the political ecosystem of the villages in the New Territories, economic efficiency and human relations in rural communities.陳煜禮.論文(哲學博士)--香港中文大學, 2007.參考文獻(p. 226-230).Source: Dissertation Abstracts International, Volume: 69-02, Section: A, page: 0713.Electronic reproduction.

    ilustraciones a color, diagramas, fotografíasEn el presente trabajo se estudia la síntesis de catalizadores basados en estructuras de Fe(III)-TiO2 (dióxido de titanio dopado con hierro), obtenidos a partir del mineral natural ilmenita extraída de arenas negras que constituyen un tipo de residuo de la industria minera (de explotación de oro) en la región de El Bagre Antioquia-Colombia. La síntesis se desarrolló mediante la extracción ácida controlada de las especies de titanio-hierro, permitiendo la obtención de catalizadores con diferentes contenidos de hierro. Dichos materiales se estudiaron mediante caracterizaciones, estructurales, superficiales, texturales y morfológicas (DRX, XPS, UV-Vis, TEM, EDX, difracción de electrones, isotermas de adsorción de N2, entre otras). Los resultados indican variaciones importantes en los diferentes sólidos, las cuales son marcadamente relacionables con el desempeño catalítico evaluado. Adicionalmente, se caracterizaron también dos sólidos comerciales (anatasa comercial y Degussa P25), con el objetivo de comparar las diferentes propiedades estudiadas. Los resultados indicaron mejores propiedades texturales y de tamaño de partícula (mayor área y menor tamaño) para la mayoría de los sólidos sintetizados y, de acuerdo al estudio estructural, se evidenció una posible substitución de Fe(III) en la estructura de TiO2 tipo anatasa. Los diferentes catalizadores sintetizados se evaluaron en la reacción de degradación fotocatalítica del ion cianuro (CN-) en medio acuoso, tanto en presencia de luz UV como de luz visible. Los resultados se compararon con las evaluaciones fotocatalíticas de los sólidos de referencia (anatasa comercial y Desgussa P25). Aunque los resultados demostraron una actividad comparable de los sólidos sintetizados con la actividad de la anatasa comercial, e inferior a la del TiO2 Degussa, bajo radiación UV, la actividad catalítica de dichos materiales sintetizados fue superior que la de los sólidos de referencia en presencia de luz visible. Además, los estudios cinéticos realizados mostraron excelente ajuste a la cinética de pseudo-primer orden mediante el modelo de Langmuir-Hinshelwood. Finalmente, se realizó la exploración de diferentes especies químicas involucradas en el mecanismo de reacción para la degradación de cianuro. Para ello, se empleó espectroscopía FTIR en modo de reflectancia difusa, mediante ensayos in situ (método transiente). Dichos experimentos permitieron verificar la desaparición progresiva de cianuro, la aparición de especies transitorias como cianato (CNO-), HCONH2 y NH2OH, entre otras. Adicionalmente, este estudio permitió entender mejor el papel del hierro incorporado en la estructura del TiO2, revelando la participación del Fe(III) estructural en la quimiadsorción del cianuro y su transformación en la superficie. Este resultado junto con aquellos obtenidos para la cinética de reacción, sugieren la participación predominante de un mecanismo tipo Langmuir-Hinshelwood. El presente estudio también permitió comprender mejor la función de los grupos -OH superficiales en el desempeño fotocatalítico de los sólidos.

The synthesis process involved a controlled acid extraction of titanium-iron species, enabling the production of catalysts with different iron contents. These materials were studied by structural, surface, textural, and morphological characterizations (X-ray diffraction, X-ray photoelectron spectroscopy, UV-Visible spectroscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, electron diffraction, nitrogen adsorption isotherms, among others). The results revealed significant variations among the different solids, which are closely correlated with the evaluated catalytic performance. Additionally, two commercial solids (commercial anatase and Degussa P25) were also characterized for comparing different properties. The findings indicate superior textural properties (higher surface areas) and lower particle sizes for most of the synthesized solids. Furthermore, based on structural analysis, a potential isomorphic substitution of Fe(III) in the anatase-type TiO2 structure was observed. The synthesized catalysts were assessed in the photocatalytic degradation performance of cyanide (CN-) in aqueous medium, under UV radiation, and also using visible light. The results were compared with the photocatalytic performance of the reference solids (commercial anatase and Degussa P25). The findings demonstrated a comparable photo-activity of the synthesized solids with the commercial anatase and a lower activity than TiO2 Degussa under UV irradiation, but the catalytic photo-activity of these synthesized materials surpassed that of the reference solids under visible light irradiation. On the other hand, the kinetic studies demonstrated an excellent correlation with the Langmuir-Hinshelwood model, using a pseudo-first order approximation. Finally, an exploration of different chemical species involved in the reaction mechanism for cyanide degradation was conducted. For this purpose, diffuse reflectance Fourier-transform infrared (FTIR) spectroscopy was employed by in situ measures (transient method). These experiments allowed the verification of the progressive disappearance of cyanide and the emergence of transient species such as cyanate (CNO-), HCONH2, and NH2OH, among others. Additionally, this study enhanced the understanding of the role of iron incorporated into the TiO2 structure, revealing the participation of structural Fe(III) in the chemisorption and transformation of cyanide on the catalyst surface. This result, and those obtained by the kinetic experiments, suggest the predominant occurrence of the Langmuir-Hinshelwood mechanism. This study also provided a better comprehension on the role of surface -OH groups in the photocatalytic performance of the solids.

    Problems of Russian Theatrical Reception of Shakespeare in Criticism of Yuli Eichenwald

    No full text
    The problem of this study lies in evaluating the methodological approach of Yuli Eichenwald (1872—1928) as a theatrical critic and theorist, specifically his writings on Shakespearean productions both in Russia and abroad. Known primarily as a literary critic, Eichenwald also wrote about theater, but his works in this area have been largely unexplored. The aim of this study is to shed light on Eichenwald's principles of theatrical criticism. The material used consists of little-known articles by Eichenwald on theater theory and Shakespearean productions from 1903 to 1927. The research employs hermeneutic and comparative methods. The findings reveal that Eichenwald demonstrates a literature-centric position in his articles on theater, according to which theater is merely an illustration of literary works. He increasingly uses productions as a pretext to discuss Shakespeare, often without mentioning the actors or directors. Eichenwald’s perception of theater as a mediator, as an auxiliary device between the play and the reader, leads to his rejection of the concept of directorial theater and the denial of the director as the author of the production. The authors conclude that Eichenwald’s theatrical criticism is a logical outcome of literature-centric judgments about theater, from Aristotle to Hegel, where theater is considered as part of literature
