The phenomenon of divorce is also inseparable from various causes, so that it becomes the reason for husband or wife to file for divorce at the religious court. In addition, the impact of divorce will have a major influence on the psychology of parties, the environment and the children are no exception. Specifically in Central Sulawesi, the number of divorces that occurred during 2016 was 2,699 cases handled by the Religious Courts in 13 districts and cities. This figure has increased when compared to 2015 only 2,490 cases. In addition, from this overall figure, it is noted that wives dominate filing for divorce compared to husbands.
ORGANIZED ECOLABELLING: NORTH-SOUTH IMPLEMENTATION OF “KICKING AWAY THE LADDER” (CASE: PALM OIL TRADE BETWEEN INDONESIA AND EUROPE)
Authors: Ayu Nanda Kartika
Published: February 2021

Liberalization is one of the theis that is expected to be able to answer the acceleration and development of the economy of developing countries. One element of liberalization is market openness that will make developing countries unite with global markets both in accepting investments or trading in exports and imports. However, along with the development of technology, the demand for the North (developed countries) in carrying out its trade began to implement an "ecolabelling" policy. For developing countries with all their industrial capabilities, ecolabelling policy is the same as the non-tarrif limitation policy given by developed countries to developing countries. So that this paper will focus on the application of the ecolabelling policy provided by the North to products that will enter the northern market, as one of the efforts of the northern countries to apply "kicking away the ladder", assuming the Southern state does not get a balanced trade surplus with the north and continues to be a developing country. This writing will use a structuralist approach that concentrates on the international structure of the north and south to describe the relationship between developed and developing countries, and uses the concept of "kicking away the ladder" to answer the situation from the implementation of ecolabelling policies for South countries. The author uses qualitative studies using literature review sources through books, journals and online media. Keywords: Ecolabelling, Kicking away the ladder.  North-South relations

Published: February 2021

After North Korea’s fourth nuclear tested in January 2016, U.S. and South Korea has an official discussion started in early February 2016. The choice to deploy the anti-missile defense system THAAD was made in July 2016 and therefore the first launchers in May 2017. This launch was in line with the tenure of President Moon Jae In at that point. President Moon Jae In initially opposed THAAD but has now accelerated its deployment in response to North Korea’s nuclear test on September 3. Even before the official THAAD discussion started, Beijing expressed its opposition to the system. Although China is additionally against  North Korea’s nuclear development, THAAD is seen as an arrange to undermine China’s strategic interests within the region. And because of this, China giving a ‘punishment’ to South Korea.                This research aims to describe how the conflict between South Korea and Chinese can happen, the impact of the place THAAD in South Korea to the relations between two countries, and the way the conflict ended. This research uses neorealism as an approach. The methodology employing a qualitative method and collecting the data employing Historical-comparative research.
Modeling of the stress-state longwall face during coal mining with the technology of roof management complete drop and stowing

Published: February 2021

Underground mining of coal deposits has a negative impact on all components of the environment. When developing a coal deposit, it is coal mining technology that determines the scale and consequences of the negative impact. Changes in the stress-strain state of the geo-environment can lead to a violation of the hydrological regime, increased gas emission from the host rocks, the initiation of gas-dynamic processes. Choice of roofing management technology - as a geotechnological method of natural and technical system management determines the environmental friendliness of coal mining and creates safety conditions. The article deals with the technology of roofing control during coal production. For this purpose mathematical modeling and analysis of stress-strain state of the bottomhole part of the coal bed for the conditions of S.M. Kirov is performed. As a result of modeling, two technologies of roof control were analyzed - complete caving and stowing. For the worked out clearing leaves filled with either caving rocks or stowing material, there are characteristic unloading zones in the massif to be worked and overworked, as well as pressure reference zones, which fall on the parts of the pillars associated with the lava. It was found out that the application of the stowing technology creates conditions for minimization of gravitational stresses in the geoenvironment, as well as significantly reduces the potential energy of form change.

Published: February 2021

Seam 14 is one of coal prospects owned by PT Alamjaya Bara Pratama (PT ABP) with an estimated coal resources of ±4,022,458.63 tons which is will be produced in 2020 so that required a pit and mine sequence design used as a guideline in carrying out coal production activities. On the other hand, the uncertainty of coal prices caused the mine sequence design to be evaluated within a certain time as the coal reference price (HBA) was altered and company’s production target. The model equation of coal reference price prediction in 2020 was carried out by using multiple linear regression method. Based on that model, prediction of coal reference price was obtained in CW 1 = $80.21, CW 2 = $81.47 and CW 3 = $82.50. The Pit 14 was designed with the consideration of company's geotechnical recommendation which is can be achieved on the conditions of stripping ratio (SR) of 6 and 7. The mine sequence was designed base on the evaluation of coal production in 2019 (CW 1 = SR > 3, CW 2 = 3 ≤ SR ≤ 6 and CW 3 = SR > 6). The calculation results of estimated revenue of Pit 14 with SR = 6 is CW 1 = US$40,131,297.12; CW 2 = US$36,431,457.31; and CW 3 = US$19,601,965.40. Estimated revenue of Pit 14 with SR = 7 is CW 1 = US$41,821,080.50; CW 2 = US$39,204,128.39; and CW 3 = US$31,715,767.60.

Three types of 6 monopoles array intelligent antennas was numerically and practically examined. The main purposes of the investigation is to guarantee that those designed antennas are feasible to implement and to install in a particular IoT based environmental surveillance network configuration. The basic differences of the three intelligent antennas lied on the frequency operations (i.e. 433 MHz, 875-915 MHz and 2.5 GHz) and the actual environment operations (whether for indoor or outdoor). The extreme differences of such frequency operations, of course, affecting the differences on the whole antenna physical dimension. The higher the frequency operation determined then the smaller the physical size of the designed antennas produced. However, the deep intelligent antenna evaluations presented in the paper is the one that operated on frequency band of 875 -915 MHz. The intelligent electronic part of six monopole wire elements arrayed on a circular ground plate was composed of LoRa chip module, Android Uno microcontroller, and the switching network part. The three parts determined whole antenna operation throughout the IoT network. The results of whole antenna examinations are thoroughly discussed in the paper.

Indonesia Government through the Ministry of Maritime Affairs and Fisheries is holding a fishery boat procurement assistance program of gross tonnage (GT) 5 to 30. In order to be effective investment for the program, a comprehensive study on fishing boat is emphasized to be carried out. This study aims to determine the investment components of a fishing boat with GT of 12, 21 and 30 based on the consideration of the local content, determine the feasibility of fishing boats investment including the local content aspect, and determine the weight of local content for the investment of fishing boat. The investment feasibilty was analysed by using Net Present Value (NPV) and Internal Rate of Return (IRR). In the present results, the three fishing boat sizes of GT 12, 21, and 30 were economic feasibility and suitable in order to support the welfare of fishermen in Sinjai Regency, South Sulawesi Province. The NPV and IRR within 10 years for the fishing boat size of GT 12 are approximately 823 million rupiahs and 77% respectively, 988 million rupiahs and IRR of 54% for GT 21, and 979 million rupiahs and 38% for GT 29. The weight of the local content aspect contributes in average of 81.47% on the investment of the fishing boat wherein the local content includes boat hull buliding, fishing equipment, and labor cost. In addition, the weight of the local content aspect for ship operation is average of 61.88% wherein the local content includes fishermen salary and fishing aggregating device.
Divergencia empresarial en la productividad total de los factores en el período de crisis y recuperación económica en el sector turístico español
Authors:   Universitat de Vic (España), Miró Albert
Published: February 2021

The main aim of this research is to contrast the existence of a positive relationship between the total factor productivity (TFP) of companies in the Spanish tourism sector and their use of Information and Communication Technologies (ICT). in the understanding that the trend is for companies to opt for ICT in‑ vestment and development to improve their TFP and their interaction with the international market (export and import) also leads to an improvement in TFP in the context of the “New” new trade theory. Likewise, the current debate on the dispersion of TFP has affected all economic sectors. In this case, the hy‑ pothesis revolves around the existence of a divergence of this variable between a period of crisis (2007‑2011) and a period of economic recovery (2012‑2017). The data from the Iberian Balance Sheet Analysis System (SABI) were extracted fto the ends of the correct development of this research which has allowed the TFP to be estimated using MCO, EF and LP, as well as the correct verification of the hypotheses using the SEM method. Three conclusions are reached: i) that the Spanish tourism sector seems to have a low level of ICT adoption in its business structure; ii) that TFP dispersion is demonstrated with respect to the two subperiods analysed (crisis and economic recovery), and that iii) internationalisation has a significant result on TFP.

Authors:   Universidad de Léon (España), González González Maria Jesús , Vallejo Pascual María Eva ,   Universidad de Léon (España)
Published: February 2021

The objective of this study is to identify the dimensions that motivate Spanish tourist demand by autonomous community of destination, from the trips as made by Spanish travellers recorded by the Resident Tourism Survey (ETR) for the year 2016, as prepared by the National Statistics Institute. The nature of the data requires the use of appropriate statistical methodology: the factorial technique called Simple Correspon‑ dence Analysis. After this analysis, the dimensions of the demand related to leisure were identified as pursuit of sun and sand; nature and / or sports tourism, and cultural tourism together with professional reasons and personal dimensions of visits to family and friends. These dimensions allow us to characterise each Spanish autonomous community according to national tourism demand, and to analyse their relative competitive posi‑ tion in relation to the diversity and structure of their tourism offer. The results obtained are a starting point for other research in subsequent years, given that the year analysed is the first with complete RTE data
Paisaje, patrimonio y turismo: expresión sistémica en la integración del Corredor Bioceánico Central
Authors:   Consejo Nacional de Investigaciones Científicas y Técnicas (Argentina), Mattioli Luisa
Published: February 2021

The territorial transformation being undergone by the Rural Department of Iglesia in San Juan‑ ‑Argentina opens up “opportunities” for development that may represent threats to its sustainability. The con‑ solidation of the Central Bio‑Oceanic corridor foresees new scenarios such as the construction of the Paso de Agua Negra International Tunnel, aimed at promoting integration and demanding, as a result, provision of utilities and amenities that broaden the horizon for regional planning, to compensate for previous partial projects. The aim of this research is to give a critical review of previous conceptual and methodological approaches to Heritage, Landscape and Tourism, as addressed in “The Plan of land use and territorial development for the rural area of Iglesia “. The aim is to provide a theoretical‑methodological approach that allows for an understanding of the systemic reality and of how landscape and heritage can be classified in a functional manner to structure tourism. Essential rural planning criteria are considered within the framework of the nascent heritage tourism vocation. The discussion and conclusions underline the systemic importance of these concepts as an input for all planning and territorial organisation. The broaching of alternative contextualised situations of development poses inter‑ disciplinary challenges to heritage conservation and possible alienation of the location from its territory.

This paper discusses the concept of “roughness” as the driving principle in the analysis of the rela‑ tionship between tourism development and built cultural heritage. It’s a theoretical reflection of an exploratory and descriptive nature that aims at synthesizing existing knowledge while providing new interpretative and analytical guidelines. Working from previous studies it was possible to identify the dialectics of the relationship between cultural heritage and tourism development with perspectives centering on two classification catego‑ ries, their intrinsic value and their market value. The study presents a re‑think of the concepts of roughness and heritage used in urban planning aimed at re‑interpreting urban space for tourism, re‑appraising their possible application to heritage sites in the city. The results may open up new perspectives for urban planning and roughness and balance out the advantages and disadvantages of re‑working the city space for tourism.

Authors:   Instituto de Investigaciones Gino Germani (Argentina), Catalano Bárbara
Published: February 2021

This paper addresses the sector of VFR tourism: visiting friends and relatives (VFR). The hypoth‑ esis is that tourism based on social ties facilitates integration in terms of social interaction and social iden‑ tification in the destination, in this case the city of Buenos Aires. The concept itself of VFR tourism is dealt with together with a description and attempted characterisation of the exact movement of this type of tour‑ ism over the last few years as a result of migratory movements with emphasis on social ties and practices. The emphasis is on the degree of social integration and identification occurring in this type of tourism. The methodology used is qualitative, based on semi‑structured interviews of key agents and is complemented with statistics designed to give fuller access to the comprehension of the context.

Published: February 2021

Objectives:

The objective of the study was to retrospectively investigate the safety and efficacy of computerized tomography-guided microwave ablation (MWA) in the treatment of Stage I non-small cell lung cancers (NSCLCs).

Material and Methods:

This retrospective, single-center study evaluated 21 patients (10 males and 11 females; mean age 73.8 ± 8.2 years) with Stage I peripheral NSCLCs treated with MWA between 2010 and 2020. All patients were surveyed for metastatic disease. Clinical success was defined as absence of FDG avidity on follow-up imaging. Tumor growth within 5 mm of the original ablated territory was defined as local recurrence. Welch t-test and Fisher’s exact test were used for univariate analysis. Hazard ratio (HR) and odds ratio (OR) were determined using Cox regression and Firth logistic regression. Significance was P < 0.05. Data are expressed as mean ± standard deviation.

Results:

Ablated tumors had longest dimension 17.4 ± 5.4 mm and depth 19.7 ± 15.1 mm from the pleural surface. Median follow-up was 20 months (range, 0.6–56 months). Mean overall survival (OS) following lung cancer diagnosis or MWA was 26.2 ± 15.4 months (range, 5–56 months) and 23.7 ± 15.1 months (range, 3–55 months). OS at 1, 2, and 5 years was 67.6%, 61.8%, and 45.7%, respectively. Progression-free survival (PFS) was 19.1 ± 16.2 months (range, 1–55 months). PFS at 1, 2, and 5 years was 44.5%, 32.9%, and 32.9%, respectively. Technical success was 100%, while clinical success was observed in 95.2% (20/21) of patients. One patient had local residual disease following MWA and was treated with chemotherapy. Local control was 90% with recurrence in two patients following ablation. Six patients (28.6%) experienced post-ablation complications, with pneumothorax being the most common event (23.8% of patients). Female gender was associated with 90% reduction in risk of death (HR 0.1, P = 0.014). Tumor longest dimension was associated with a 10% increase in risk of death (P = 0.197). Several comorbidities were associated with increased hazard. Univariate analysis revealed pre-ablation forced vital capacity trended higher among survivors (84.7 ± 15.2% vs. 73 ± 21.6%, P = 0.093). Adjusted for age and sex, adenocarcinoma, and neuroendocrine histology trended toward improved OS (OR: 0.13, 0.13) and PFS (OR: 0.88, 0.37) compared to squamous cell carcinoma.

Conclusion:

MWA provides a safe and effective alternative to stereotactic brachytherapy resulting in promising OS and PFS in patients with Stage I peripheral NSCLC. Larger sample sizes are needed to further define the effects of underlying comorbidities and tumor biology.

Objectives:

Reproductive tract infection/sexually transmitted infection (RTI/STI) has become a silent epidemic that devastates women’s life. Improper maintenance of menstrual hygiene is one of the important causes of ascending infection of genital tract leading to RTI. The objectives of the study were to assess reproductive health status and menstrual hygiene practices of adolescent girls residing in the urban slums.

Material and Methods:

A community-based cross-sectional study conducted among adolescent girls residing in urban slums situated under field training area of the Department of Community Medicine, S.C.B. Medical College, Cuttack, Odisha. From among 10 Anganwadi Centres (AWCs) under this field training area, four AWCs having relatively more slum population were selected for the study. A total of 277 adolescent girls were studied who had attended menarche. Pre-designed and pre-tested questionnaire was used to collect information regarding the reproductive health status of adolescent girls.

Results:

Among the 277 adolescent slum girls, 116 (41.9%) had no complaint related to menstruation and reproductive health. Most of the adolescent girls had dysmenorrhea followed by irregular cycles, menorrhagia, and scanty menstruation. As per syndromic approach, 15.2% of adolescent girls had symptoms of RTI/STI. Only 36.8% of girls were using sanitary napkins.

Conclusion:

More than half of adolescent slum girls had one or more menstrual problems, the common being dysmenorrhea. Symptom of RTI/STI was also a common problem encountered among these girls as almost one in seven girls were having these symptoms and this was more among the girls not using sanitary pad during menstruation.

Quantum Alice and silent Bob: Qubit-based Quantum Key Recycling with almost no classical communication
Authors: Leermakers Daan , Skoric Boris
Published: February 2021

We answer an open question about Quantum Key Recycling (QKR): Is it possible to put the message entirely in the qubits without increasing the number of qubits compared to existing QKR schemes? We show that this is indeed possible. We introduce a prepare-and-measure QKR protocol where the communication from Alice to Bob consists entirely of qubits. As usual, Bob responds with an authenticated one-bit accept/reject classical message. Compared to Quantum Key Distribution (QKD), QKR has reduced round complexity. Compared to previous qubit-based QKR protocols, our scheme has far less classical communication. We provide a security proof in the universal composability framework and find that the communication rate is asymptotically the same as for QKD with one-way postprocessing.

Actualmente es importante tener en cuenta que los estudiantes están involucrados en el mundo tecnológico de manera abrumadora y no tienen bien en claro cómo realizar sus actividades académicas de manera que acorten tiempos y den gran utilidad para la elaboración de sus actividades, más aún en un contexto de aislamiento producido por la pandemia por covid-19. Ante ello, se propuso examinar el resultado de la aplicación de la Multiplataforma de sistema información de contenido educacional para desarrollar la competencia digital en estudiantes de una institución educativa de la región Lambayeque. Metodológicamente se sigue un enfoque cuantitativo con diseño cuasiexperimental, para ello se utilizaron los métodos hipotético deductivo y empírico. Se arroja que existe inicialmente un desarrollo poco significativo en ambos grupos focalizados, lo mismo que fue superado, en el caso del grupo experimental, a partir de aplicar un estudio piloto. Finalmente, se concluye que, si se utiliza la multiplataforma de sistemas de información de contenido educativo mejora significativamente la competencia digital en los estudiantes de educación secundaria que formaron parte del estudio, dado que, el valor de la prueba normal estándar (z) es significativo (p < 0,05 “Se rechaza H0”). Es decir, el nivel de conocimiento mejora en el grupo que se aplicó el estímulo.
State of stress in central and eastern North American seismic zones
Authors: Mazzotti S , Townend John
Published: February 2021

We use a Bayesian analysis to determine the state of stress from focal mechanisms in ten seismic zones in central and eastern North America and compare it with regional stress inferred from borehole measurements. Comparisons of the seismologically determined azimuth of the maximum horizontal compressive stress (S HS ) with that determined from boreholes (S HB ) exhibit a bimodal pattern: In four zones, the S HS and regional S HB orientations are closely parallel, whereas in the Charlevoix, Lower St. Lawrence, and Central Virginia zones, the S HS azimuth shows a statistically significant 30°-50° clockwise rotation relative to the regional S HB azimuth. This pattern is exemplified by the northwest and southeast seismicity clusters in Charlevoix, which yield S HS orientations strictly parallel and strongly oblique, respectively, to the regional S HB trend. Similar ~30° clockwise rotations are found for the North Appalachian zone and for the 2003 Bardwell earthquake sequence north of the New Madrid zone. The S HB /S HS rotations occur over 20-100 km in each seismic zone, but they are observed in zones separated by distances of up to 1500 km. A possible mechanism for the stress rotations may be the interaction between a long-wavelength stress perturbation source, such as postglacial rebound, and local stress concentrators, such as low-friction faults. The latter would allow low-magnitude (<10 MPa) postglacial rebound stresses to locally perturb the preexisting stress field in some seismic zones, whereas postglacial rebound stresses have little effect on the intraplate state of stress in general. © 2010 Geological Society of America.

©2019. American Geophysical Union. All Rights Reserved. The 14 November 2016 Mw7.8 Kaikōura earthquake in the northern South Island, New Zealand, involved highly complex, multifault rupture. We combine data from a temporary network and the permanent national seismograph network to repick and relocate ~2,700 aftershocks of M≥3 that occurred between 14 November 2016 and 13 May 2017. Automatic phase-picking is carried out using REST, a newly developed hybrid method whose pick quality is assessed by comparing automatic picks for a subset of 138 events with analysts' picks. Aftershock hypocenters computed from high-quality REST picks and a 3-D velocity model cluster almost exclusively in the shallow crust of the upper plate and reveal linkages at depth between surface-rupturing fault segments. Only eight aftershocks are relocated on a deeper structure positioned between patches of geodetically detected afterslip. This indicates that afterslip has not triggered significant earthquake activity on the subduction interface during the period of aftershock activity analyzed.

© 2019 K. C. Weaver et al. The 2016 Mw 7.8 Kaikōura earthquake induced groundwater level changes throughout New Zealand. Water level changes were recorded at 433 sites in compositionally diverse, young, shallow aquifers, at distances of between 4 and 850 km from the earthquake epicentre. Water level changes are inconsistent with static stress changes but do correlate with peak ground acceleration (PGA). At PGAs exceeding 2 m/s2, water level changes were predominantly persistent increases. At lower PGAs, there were approximately equal numbers of persistent water level increases and decreases. Shear-induced consolidation is interpreted to be the predominant mechanism causing groundwater changes at accelerations exceeding 2 m/s2, whereas permeability enhancement is interpreted to predominate at lower levels of ground acceleration. Water level changes occur more frequently north of the epicentre, as a result of the fault's northward rupture and resulting directivity effects. Local hydrogeological conditions also contributed to the observed responses, with larger water level changes occurring in deeper wells and in well-consolidated rocks at equivalent PGA levels.

Matched-filters are an increasingly popular tool for earthquake detection, but their reliance on a priori knowledge of the targets of interest limits their application to regions with previously documented seismicity. We explore an extension to the matched-filter method to detect earthquakes and low-frequency earthquakes on local to regional scales. We show that it is possible to increase the number of detections compared with standard energy-based methods, with low false-detection rates, using suites of synthetic waveforms as templates. We apply this to a microearthquake swarm and an aftershock sequence, and to detect low-frequency earthquakes. We also explore the sensitivity of detections to the synthetic source's location and focal mechanism. Source-receiver geometry has a first-order control on how sensitive matched-filter detectors are to variations in source location and focal mechanism, and this likely applies to detections made using both synthetic and real templates.

Principal slip zone gouges recovered during the Deep Fault Drilling Project (DFDP-1), Alpine Fault, New Zealand, were deformed in triaxial friction experiments at temperatures, T, of up to 350°C, effective normal stresses, σn′, of up to 156 MPa, and velocities between 0.01 and 3 μm/s. Chlorite/white mica-bearing DFDP-1A blue gouge, 90.62 m sample depth, is frictionally strong (friction coefficient, μ, 0.61-0.76) across all experimental conditions tested (T = 70-350°C, σn′ = 31.2-156 MPa); it undergoes a transition from positive to negative rate dependence as T increases past 210°C. The friction coefficient of smectite-bearing DFDP-1B brown gouge, 128.42 m sample depth, increases from 0.49 to 0.74 with increasing temperature and pressure (T = 70-210°C, σn′ = 31.2-93.6 MPa); the positive to negative rate dependence transition occurs as T increases past 140°C. These measurements indicate that, in the absence of elevated pore fluid pressures, DFDP-1 gouges are frictionally strong under conditions representative of the seismogenic crust.
Fundamental and higher-mode Rayleigh wave characteristics of ambient seismic noise in New Zealand

In order to use ambient seismic noise for mapping Earth's structure, it is important to understand the spatiotemporal characteristics of the noise field. This study uses data collected during four austral winter months of 2002 to investigate New Zealand's ambient seismic noise field in the double-ocean-wave-frequency range (0.1-0.3 Hz). It is shown via beamforming analysis that there are two distinct dispersive waves in the data. These waves can be separated. Their estimated phase velocities (2.5-2 and 4-3 km/s in the frequency range 0.14-0.25 Hz) match well with fundamental and higher-mode Rayleigh dispersion curves. Studies of double-wave-frequency microseisms elsewhere generally show the Rayleigh noise fields to be dominated by fundamental mode waves. The reason why higher-mode signals are observed here may reflect a combination of long ocean wave periods, large waveheights, the direct deep water approach to narrow continental margins, and the proximity of the seismograph array to the source regions.

Spatially and temporally systematic hydrologic changes within large geoengineered landslides, Cromwell Gorge, New Zealand, induced by multiple regional earthquakes
Authors: O'Brien GA , Cox SC , Townend John
Published: February 2021

©2016. American Geophysical Union. All Rights Reserved. Geoengineered groundwater systems within seven large (23 × 104–9 × 106 m2), deep-seated (40–300 m), previously slow-creep (2–5 mm/yr.) schist landslides in the Cromwell Gorge responded systematically to 11 large (Mw > 6.2) earthquakes at epicentral distances of 130–630 km between 1990 and 2013. Landslide groundwater is strongly compartmentalized and often overpressured, with permeability of 10−17 to 10−13 m2 and flow occurring primarily through fracture and crush zones, hindered by shears containing clayey gouge. Hydrological monitoring recorded earthquake-induced meter- or centimeter-scale changes in groundwater levels (at 22 piezometers) and elevated drainage discharge (at 11 V notch weirs). Groundwater level changes exhibited consistent characteristics at all monitoring sites, with time to peak-pressure changes taking ~1 month and recovery lasting 0.7–1.2 years. Changes in weir flow rate near instantaneous (peaking 0–6 h after earthquakes) and followed by recession lasting ~1 month. Responses at each site were systematic from one earthquake to another in terms of duration, polarity, and amplitude. Consistent patterns in amplitude and duration have been compared between sites and with earthquake parameters (peak ground acceleration (PGA), seismic energy density (e), shaking duration, frequency bandwidth, and site amplitude). Shaking at PGA ~0.27% g and e ~ 0.21 J m−3 induced discernable gorge-wide hydrological responses at thresholds comparable to other international examples. Groundwater level changes modeled using a damped harmonic oscillator characterize the ability of the system to resist and recover from extrinsic perturbations. The observed character of response reflects spectral characteristics as well as energy. Landslide hydrological systems appear most susceptible to damage and hydraulic changes when earthquakes emit broad-frequency, long-duration, high-amplitude ground motion.

PERCEPTION AND INTERPRETATION OF CREATIVITY OF ALISHER NAVOI IN FRENCH ORIENTAL STUDIES
Authors:   Samarkand  State  Institute  of  Foreign Languages of Uzbekistan, Kholbekov Mukhammadjon
Published: February 2021

Information about Navoi began to reach Europe as early as the 17th century. Over time, he became one of the most famous people of the East in Europe. His works are translated into some European languages in separate fragments. Similar works have been translated in France, England, Italy, Holland, and other countries [Захидов 1961:13-14]. In the 19th century, the study of Navoi art in these countries was especially intensified. His works are translated, scientific works about his work are written, dictionaries for his works are compiled, etc.The study of creativity and translations of works by A. Navoi after the works of Christopher and D’erbelo falls on the first half of the XIX century. One of the founders of the “School of living Oriental languages”, the famous orientalist Sylvester de Sasi (1758-1838) in his research also touched on the work of Navoi. As the Russian orientalist M. Nikitsky testifies, S. de Sasi, using the books of Davlatshah Samarqandi and Som Mirza, wrote a great work about the life and work of the classics of Turkic literature. In his book, he noted the ambiguity of Navoi’s work and his contribution to the development of Uzbek literature. S. de Sasi described the life and work of the poet in more detail, but he does not give a scientific and critical assessment of his individual works [Никитский 1856:3].Another French orientalist, Etienne Catremer (1782-1857), published his works on the culture, history and literature of the Uzbek people in the Journalasiatique. His early articles “Essays on the history of the Abbasid dynasty” (1835) and “On the life of Sultan Shahrukh” (1836) aroused great interest among European scholars. Especially appreciated is his book “anthology of Eastern Turkic literature”, published in 1841 [Chrestomatie 1841]. In the Preface to this book, the author writes that he included in the anthology “Muhakamat al-lugatain” (“judgment on two languages”) and “Tarikhi Muluk-i Azham” (“History of the Persian kings”) by A. Navoi, excerpts from Babur’s “Baburname” and other monuments of Uzbek literature. The 2nd volume of this book was to publish “an Essay on the life and work of Alisher Navoi”. But the second part of the book was never published. E. Catremer also collected a large library of Oriental literature. Later, his student M. Galm published a catalog (a total of 3,825 names of sources) of the Catremer library, which included 65 names of sources in Turkic languages. Here we find the names of works by A. Navoi, Babur, Abu-l-Ghazi Khan, Gulbadanbegim, etc [Bibliotheque Quatremere 1858:268].
