ABSTRAKGerakan tanah di kompleks perkantoran Kabupaten Sukabumi di Jajaway, Palabuhanratu, terjadi di luar perkiraan dan perencanaan pembangunan sebelumnya. Untuk melihat kondisi dan luasan daerah gerakan tanah dan dalam usaha mengurangi resiko kerugian lebih besar, diperlukan identifikasi bidang gelincir gerakan tanah di kompleks tersebut. Bidang gelincir dicari berdasarkan model tahanan jenis yang diperoleh dari survei pengukuran geolistrik. Akuisisi data dilakukan pada 7 lintasan, dengan 6 lintasan berarah utara-selatan dan 1 lintasan berarah barat-timur. Metode akusisi yang digunakan adalah tahanan jenis multielektrode dengan konfigurasi dipole-dipole. Hasil penelitian membuktikan bahwa kondisi perlapisan batuan lepas tetapi lebih berat di atas lapisan lempung merupakan salah satu penyebab kejadian pergerakan tanah. Kejadian itu sangat terlokalisir karena kondisi seperti itu tidak ditemukan pada lintasan lainnya.Kata kunci: bidang gelincir, geolistrik, gerakan tanah, konfigurasi dipole-dipole, tahanan jenisABSTRACTGround movement in the Sukabumi Regency office complex (Jajaway, Palabuhanratu), occurred unexpectedly. To reduce the potential risk, we need to identify the slip surface to detect the possibility of more landslides. The resistivity model by the dipole-dipole geoelectrical method was applied to find the slip surface. Data acquisition was carried out in 7 lines: 6 north-south lines and 1 east-west line. The resistivity models present the distribution of resistivity below the surface. Above this clay layer, there is a higher resistivity layer, which is related to sandy tuff and breccia. The condition might cause the previous creeping type of ground movement. The type of layering is not found in the other lines. Therefore we do not expect a similar ground movement would occur in those lines.Keywords: dipole-dipole configuration, geoelectrical, landslide, resistivity, slip surface

ABSTRACTFor the last several years, we have been developing and characterizing “mobile” micro- and nano-instruments for use on-site (e.g., in the field). Although such portable, battery-operated instruments are much smaller that their laboratory-scale counterparts, sometimes they provide comparable performance and they often offer improved capabilities. As such, they are expected to cause a paradigm shift in classical chemical analysis by allowing practioners to “bring the lab (or part of it) to the sample”. Two classes of examples will be used as the means with which to illustrate the power of micro- and nano-instruments. One class involves a “patient” as the sample and an ingestible capsule-size spectrometer used for cancer diagnosis of the gastro intestinal tack as (part of) “the lab”. The other involves the “environment” as the sample and a portable, battery-operated, miniaturized instrument that utilizes a PalmPilot™ with a wireless interface for data acquisition and signal processing as (part of) “the lab”. To discuss how to electrically power such miniaturized instruments, mobile energy issues will be addressed. Particular emphasis will be paid to current or anticipated future applications and to the paradigm shifts that may prove essential in powering the next generation of miniaturized instruments.

This article examines the impact of Japan on U.S.-Soviet relations during Richard Nixon's first term as U.S. president. Drawing heavily on recently declassified documents pertaining to back-channel negotiations between Nixon's national security adviser, Henry Kissinger, and Soviet Ambassador Anatolii Dobrynin, the article explains why no Soviet-Japanese rapprochement proved feasible even during the height of East-West détente. The enduring hostility was in contrast to the realignments of the other major powers during this period.

Different grape processing, fermentation and aging technologies were compared in our study on the white wine-grape variety Grüner Veltliner between 2012 and 2014 in Hungary,Cserszegtomaj. The vines are grown on brown forest soil on dolomite bedrock, stocks were planted 3x1 m row and vine space, respectively in our experimental area. The soil has slightly alkaline pH, the orientation of the vine rows are East-West. The training system is modified Guyot cordon, with 1 m trunk height and cane pruning method. After the harvest half of the yield has been put into the de-stemmer crusher before pressing while the other half has been pressed immediately (whole bunches). From the filtered and bottled wine anthocyanin, and polyphenol content was measured in 2013 and 2014. Another enological technology testing experiment has been set on aging of Grüner Veltliner in 2013. The wine was fermented with addition of fine lees from juice sedimentation. Traditional (racking only), battonage and fast ready-made aging technologies have been set together, each treatment in three replicates were observed.

The discovery of Skrugard in 2011 was a significant milestone for hydrocarbon exploration in the Barents Sea. The result was a positive confirmation of the play model, prospect evaluation, and the seismic hydrocarbon indicators in the area. In addition, the well result was encouraging for the CSEM interpretation and analysis that had been performed. Prior to drilling the 7220/8-1 well, EM resistivity images of the subsurface across the prospect had been obtained along with estimates of hydrocarbon saturation at the well position. The resistivity distribution was derived from extensive analysis of the multiclient CSEM data from 2008. The analysis was based on joint interpretation of seismic structures and optimal resistivity models from the CSEM data. The seismic structure was furthermore used to constrain the resistivity anomaly to the Skrugard reservoir. Scenario testing was then done to assess potential alternative models that could explain the CSEM data in addition to extract the most likely reservoir resistivity. Estimates of hydrocarbon saturation followed from using petrophysical parameters from nearby wells and knowledge of the area, combined with the most likely resistivity model from CSEM. Our results from the prewell study were compared to the postwell resistivity logs, for horizontal and vertical resistivity. We found a very good match between the estimated CSEM resistivities at the well location and the corresponding well resistivities. Thus, our results confirmed the ability of CSEM to predict hydrocarbon saturation. In addition, the work demonstrated limitations in the CSEM data analysis tools as well as sensitivity to acquisition parameters and measurement accuracy. The work has led to more CSEM data acquisition in the area and continued effort in development of our tools for data acquisition and analysis.

Abstract This paper will shed light upon the history and current state of Japanese Zen Buddhism in Europe. Japanese Zen has mainly been transmitted in two ways among European countries: via the group founded by Deshimaru Taisen, and through Christian Zen. Deshimaru went to Europe and taught Zen. His teaching represented Zen as a wholistic, scientific, and peaceful Eastern religion. Though his group initially expanded greatly, it split into several subgroups following Deshimaru’s death. On the other hand, Sanbō Kyōdan promoted ecumenical integration between Christianity and Zen. The longstanding interest in Zen among Christians can be seen in the contemporary “spiritual exchange of the East-West.” Concerning the current state of Zen in Europe, data show that there are more than 270 Zen centers in Europe, located in 24 countries. An analysis of the contemporary situation thus demonstrates that European Zen is mobile, has various forms, and has influenced Japanese institutions.

This chapter argues that the 8 May 1945 massacre is the direct impetus behind the 1954 Algerian revolution. It is a major game changer in the rapport between the Algerian intelligentsia and the Occident resulting in a political divorce, which engendered an important volume of literature that recorded the painful birth of a nation painfully tearing itself from the domination of another. Caught between the traumas of yesterday’s colonial night, and the uncertainties of tomorrow, the expression of these anxieties produced literary accounts of high value. Their themes varied from a narrative of alienation, to rebellion against colonial injustice, a questioning of decolonisation and imperialism, a revolt against social prejudice, and most importantly an endless search for identity, and an account of the East-West encounter demonstrating all the while that the other of the Maghrebi novel is the Occident. While decolonisation often meant a repudiation of everything brought by the ex-coloniser including its language, this position tended to lose its intensity as the ex-colonised came to realise the eternal dichotomy between two Occidents: the Occident as a colonial power which is now defeated, and the Occident as a culture and a civilisation which continues to captivate and enchant the Maghrebi person.

AbstractThis article discusses some characteristic methods and structures shared by modern Western and classical Chinese poetry, focusing on the works of Georg Trakl and major poets of the T’ang dynasty. Among the similarities examined are the preference for concrete imagery over abstract, discursive statement; the paratactical juxtaposition of images, which leaves their logical, temporal, and grammatical relationships unspecified and often ambiguous; and the tendency for images to become “ciphers” that suggest, but do not support, metaphorical interpretation. There is also a reluctance to obtrude a first-person speaker onto the scene, and this has led some critics to label Symbolist-post-Symbolist and Chinese poetry “impersonal”; this essay argues, however, that the hidden subjectivity of even the most “impersonal” poem should not be overlooked. Nevertheless, the omission of subject does frequently increase ambiguities among the other elements of a work and contributes to the “poetics of discontinuity” common to the two traditions.

This study focuses on the method to determine the slip surface in waterfront soil slope analysis under static and seismic conditions. Based on the limiting equilibrium theory and the stress analyzing method, a new method to determine the slip surface is suggested. In the method, the two basic assumptions are considered in order to solve the problem. One is that the slip surface comprises a series of straight lines, and the other is that the interslice boundary is an inclined plane. Three balance equations for any slice are proposed. The iterative method to solve the balance equations is also suggested. In the new method, the slip surface is obtained slice by slice going from downhill to uphill in terms of the balance equations of the slice, not predefined.

Temperature, humidity and precipitation have a strong influence on the generation of diseases in different crops, especially in vine. In recent years, advances in different disciplines have enabled the deployment of sensor nodes on agricultural plots. These sensors are characterised by a low cost and so the reliability of the data obtained from them can be compromised, as they are built from low-confidence components. In this research, two studies were carried out to determine the reliability of the data obtained by different SEnviro nodes installed in vineyards. Two networks of meteorological stations were used to carry out these studies, one official and the other professional. The first study was based on calculating the homogenisation of the data, which was performed using the Climatol tool. The second study proposed a similarity analysis using cross-correlation. The results showed that the low-cost node can be used to monitor climatic conditions in an agricultural area in the central zone of the province of Castelló (Spain) and to obtain reliable observations for use in previously published fungal disease models.
