Determination of Source Parameters for Central and Eastern North American Earthquakes (1982–1986)
Authors: Nguyen B. V. , Herrmann R. B.
Published: July 2019

A search technique is applied to determine focal mechanisms from the surface-wave spectral amplitudes of recent earthquakes in the eastern U. S. and Canada. The technique provides the five source parameters of dip, slip, strike, depth, and seismic moment through a combination of criteria requiring best correlation coefficients, least residuals between theoretical and observed spectral-amplitudes and equality between independent seismic moment estimates from Love and Rayleigh wave data.

This technique is applied to eight earthquakes of mb ≈ 5 that occurred in the North American continent in recent years. The focal mechanism results, constrained by P-wave first motions, indicate that near horizontal pressure axes are in the ENE-WSW for the 1982 Miramichi, New Brunswick (Canada) mainshock and one large aftershock (another large aftershock has ESE-WNW P-axis), the 1982 Gaza, New Hampshire mainshock, the 1982 Arkansas mainshock, the 1983 Goodnow, New York mainshock, and the 1986 Perry, Ohio mainshock. On the other hand a near horizontal tension axis in the direction NNE-SSW is found for the 1984 Wyoming mainshock in the western part of North American continent. The results obtained are consistent with the regional stress patterns and generally agree with the solutions of other investigators who used other aspects of the seismic wavefield.
Recurrence Expectation for Earthquakes in Eastern North America South of 50°N Latitude
Authors: Howell B.F.
Published: July 2019

Gumbel’s method of extremes is used to estimate average recurrence intervals for four areas: eastern North America south of 50° N latitude, eastern United States, sixteen seaboard states and nine industrialized states (20, 44, 98 and 250 years, respectively, for magnitude 5.8).

The next large earthquake in eastern North America is likely to occur in a place that has not experienced even a moderate earthquake because past large earthquakes have tended to occur at places with no history of significant earthquakes. The rate of occurrence of very large earthquakes in the eastern United States has been lower for the past 48 years than previously, leading to the expectation that a magnitude 5.8 or larger earthquake may occur somewhere soon.
Crustal Structure Beneath the Atlantic Coastal Plain of South Carolina
Authors: Luetgert James H. , Benz Harley M. , Madabhushi Sriram
Published: July 2019

In April, 1991, a northwest-southeast trending 120-km-long seismic refraction/wide-angle reflection profile was recorded across the Atlantic Coastal Plain of South Carolina, the passive margin of the eastern United States formed by Mesozoic extension during the opening of the Atlantic and Gulf of Mexico. Two-dimensional ray tracing of first arrivals and reflections indicates large lateral velocity variations in the upper 5 km of the crust. From northwest to southeast along the profile, Coastal Plain sediments thicken from a few tens of meters to more than 1 km. P-wave velocities within the sediments range from 1.85 to 3.5 km s−1, while intercalated basalts have velocities of 5.2–5.5 km s−1. The top of the crystalline basement dips eastward and is characterized by velocities of 6.0–6.2 km s−1. High velocities of 6.2 km s−1 within the crystalline basement are locally restricted to a shallow 25-km-wide zone adjacent and east of the Dunbarton basin. Seismic, gravity and magnetic observations suggest that this anomaly represents a pre-Cretaceous mafic intrusion formed during Mesozoic rifting. Mesozoic rifting is also evident from observed eastward thinning of the crust from 37 to 32 km along the profile.
Comparison of two doses of Dexmedetomidine on hemodynamic parameters of patients undergoing spinal anesthesia
Authors: Reddy B. Srinivasulu , Surya K.
Published: July 2019

Background: Dexmedetomidine is considered as safe adjuvant as it does not cause depression of the respiratory system. Whether it can be used in the dose of 5 mcg or 10 mcg needs evaluation. Objective of the study was to compare two doses of dexmedetomidine on hemodynamic parameters of patients undergoing spinal anesthesia.Methods: Present study was hospital based follow up study. 80 patients were studied who were of age 18-60 years. These patients were operated using spinal anesthesia. History in detail was taken. They were examined thoroughly and investigated. Informed written consent is taken. Two groups were made. One group with 30 patients received dexmedetomidine 5 mcg. Second group with 50 patients received 10 mcg dexmedetomidine.Results: All baseline parameters were similar in two group patients. Heart rate at various intervals was also similar in two groups patients. Systolic blood pressure at various intervals was also similar in two groups patients. Diastolic blood pressure at various intervals was also similar in two groups patients. Highest level of sensory block was also similar in two groups patients. Patients in 5 mcg group had both the sensory and motor block more compared to patients in 10 mcg group. All other parameters were similar in two group of patients.Conclusions: Dexmedetomidine in doses of 5 mcg and 10 mcg has been found to have similar effect on hemodynamic parameters of the patients. So, it can be used in any of these two doses without affecting the hemodynamic parameters.
A comparative study of serum ascitic fluid albumin gradient with ascitic fluid total protein in evaluating the etiology of ascites
Authors: Gopi Manigandan , Hanifah Mohamed
Published: July 2019

Background: The traditional method of classification of ascites by AFTP offers little insight into the pathophysiology of ascites formation and it has many drawbacks. In order to overcome it, the classification of ascites based on SAAG has emerged. Even SAAG has some draw backs like non correlation with ascites due to non-alcoholic cirrhosis and difficulty in identifying the ascites due to mixed etiology. This study is conducted to compare the diagnostic accuracies of SAAG and AFTP in identifying the pathophysiology of ascites.Methods: A total of fifty patients who were admitted with ascites were included in the study.  Ascitic fluid total protein and SAAG were calculated. They were classified on the basis of SAAG into High SAAG and Low SAAG and on the basis of AFTP into Transudate and Exudate. After the etiology of ascites evaluated by various diagnostic procedures, the sensitivity, specificity and diagnostic accuracy of SAAG and AFTP in identifying the pathophysiology of ascites calculated sepereately. The diagnostic accuracies of SAAG and AFTP were compared statistically.Results: The sensitivity of SAAG was found to be 86.84% and that of AFTP  60%. The specificity of SAAG was found to be 83.33% and that of AFTP was found to be 60%. The diagnostic accuracy of SAAG was found to be 86% and that of AFTP was found to be 60%. The diagnostic accuracy of SAAG and AFTP for individual etiologies of ascites were found and compared. SAAG was found to be superior to AFTP with a P value of <0.01 which was statistically significant.Conclusions: The sensitivity and specificity of SAAG was superior to AFTP in identifying the etiology of ascites.

Authors: Chaudhary Ajeet Singh , Tuteja Vinay , Agarwal M. K. , Jain Gunja , Luniwal Hemant
Published: July 2019

Visceral malignancies often present as cutaneous lesion and are an important clue towards the diagnosis. Authors report a case of a 64 years old male, who presented to us with right hemiparesis and multiple purple-red skin lesions. Systematic evaluation, thorough history and histological examination of the skin lesion showing the characteristic lesion lead to a final diagnosis of Renal Cell Carcinoma. Although in the history and physical examination there was no sign of Renal Cell Carcinoma, but eventually the case turned out to be an extensively spread cancer. This kind of Cutaneous lesions in a case of RCC is a rare phenomenon and has not been frequently mentioned in the previous literature, thus this case reminds us about the importance of a detailed clinical look out in each and every patient and various clues to make a correct and timely diagnosis of systemic diseases. The list of visceral malignancies causing cutaneous metastasis is quite long and requires a battery of test to diagnose the same.

Containerisation in the Baltic Sea Region: Development, Characteristics and Contemporary Organisation
Authors: Serry Arnaud
Published: July 2019

The main focus of the paper is on the container system development in the Baltic Sea Region studying cotemporary changes and organisation, as well as explaining the main driving forces of this situation.

The Baltic Sea is a transport corridor between Eastern and Western Europe. Over the last decade maritime transport in the Baltic Sea area has changed significantly. The disintegration of the Soviet Union forced Russia to start developing its own Baltic ports and terminals and to find new routes to export its oil and gas. The Baltic ports have welcomed a remarkable growth, especially in oil transportation and containerised flows.

The geographical configuration of the region naturally places it away from major global shipping lines. This situation is accentuated by the organisation of maritime regular lines, centred in Northern European ports. For this reason, the regional container network is mainly made up of feeder services.
Transformations of Urban Electric Transport in Ukraine after 1991 in the View of Transport Policy
Authors: Rudakevych Ivan , Sitek Sławomir , Soczówka Andrzej
Published: July 2019

The article presents, in a multifaceted manner, the changes that occurred in urban electric transport in Ukraine after 1991. The purpose of the article is to research the diversification of the degree and directions of development and transformation of urban electric transport systems in the context of the transport policy. The legal and financial conditions for the functioning and development of the system are discussed, and a SWOT analysis of the current situation is carried out. In order to assess the direction of the changes occurring on individual networks, a synthetic index was used, constructed on the basis of the statistical data from 25 years available. The research has shown that in 1991‒2016, in the vast majority of Ukrainian cities there was a regression in urban electric transport, the largest in the east of Ukraine. That was of a bipartite nature: in the first years it practically applied to all networks, later a polarization in cities occurred ‒ in parts of cities the situation of urban electric transport has improved slightly. In the context of numerous diagnosed problems, the challenges faced by urban electric transport in Ukraine were indicated.
La consolidación de la educación pública brasileña en el estado de Mato Grosso (1889-1908)
Authors: Vieira Campos Ferreira Nilce , Montes Geles Yesica Paola
Published: July 2019

El presente artículo tiene como objetivo examinar el fortalecimiento de la educación pública mato-grossense en el periodo de 1889-1908, a través del análisis de las legislaciones gubernamentales descritas en los informes emitidos por los responsables de la educación pública en dicho tiempo. Para ello, se plantearon dos preguntas base que orientaron el análisis: ¿hubo consonancia entre la defensa de la escuela pública moderna y el modelo de escuela establecida en Cuiabá, capital del estado de Mato Grosso?; y ¿las escuelas públicas cuiabanas fueron subsidiadas con los materiales y la infraestructura adecuados para el desarrollo de actividades en el aula? Se utilizaron, como origen de la información, las fuentes históricas oficiales, tanto como los mensajes de los presidentes estatales, las leyes o los decretos relacionados con la educación pública primaria y los informes de la educación pública desde 1889 hasta 1908. Gracias al estudio se concluye que, en 1889, año de la proclamación de la República de Brasil, persistían los problemas existentes en las escuelas de Mato Grosso como la precariedad y la falta de recursos para la enseñanza, así como falta de profesionales cualificados, temas que fueron expuestos repetidamente en los mensajes emitidos por el gobierno.

Recently, cancer is  globally the second highest cause of death with a total death about 8.8 million in 2015. There are some  therapy of cancer, one of them  by using cyclophosphamid chemotherapy, but this regimen has side effects of bone marrow depression through its active metabolite of 4 hydroxy cyclophpsphamid and increase ROS which will  effect on serum MDA elevation. Increased MDA serum can be prevented by giving an antioxidant or plants that have various antioxidants, such as kenitu  leaves. The aim of this study was to determine the effect of antioxidants in  kenitu leaves (Chrysophyllum cainito L.)) extract  to MDA serum leves of  cyclophosphamid-induced mice. This study used quasi experimental method with post test only controlled group  design by using 1 normal control group, 1 negative control group (cyclophosphamid), and 5 treatment groups (dose of extract 50mg/kgBW; 100mg/kgBW; 200mg/kgBW; 400mg/kgBB; and 800mg / kgBW). The results of the treatment group dose 100mg/kgBB showed the  average of MDA serum levels was 1.94 μg/mL which is the highest decrease in this study. The result of Kendall Tau correlation test showed the effect of kenitu leaves extract to MDA serum level had p = 0.013 and correlation coefficient = 0.431.

Uma proposta de descrição do sistema de MENSAGEM na organização funcional discurso
Authors: Figueredo Giacomo Patrocinio
Published: July 2019

Este artigo investiga as funções linguísticas responsáveis pela organização textual do discurso. Mais especificamente, descreve o sistema semântico-discursivo de mensagem, o qual responde pelo gerenciamento da produção e acúmulo de significado no texto. Para tanto, explora a estrutura do discurso tendo como ponto de partida a relação entre esse e a gramática oracional que o realiza. Em seguida, descreve cada opção do sistema, bem como a forma como opera ao longo do fluxo textual, e assim assumindo valor nas relações que estabelece frente a outras opções. Para promover a descrição, utilizou-se o português brasileiro como língua de investigação. Um corpus com 100 mil tokens foi compilado com base na tipologia da língua no contexto de cultura. Os textos foram analisados segundo a manifestação estrutural, relações funcionais entre opções sistêmicas, e o significado gerado pela organização discursiva das mensagens. Ao final, o artigo mostra como as diferentes opções de mensagempré-selecionam funções na gramática, fazendo com que cada mensagem seja contextualizada, incorporando-se ao texto de forma a dar algum direcionamento à fase a qual pertence. O artigo mostra ainda o potencial sistêmico pelo qual diferentes tipos de texto determinam opções distintas na gramática e semântica textuais.
Um tratamento unificado da omissão e da expressão de sujeitos e objetos diretos pronominais de 3ª pessoa em português brasileiro
Authors: Othero Gabriel de Ávila , Spinelli Ana Carolina
Published: July 2019

Este trabalho apresenta um estudo sobre dois fenômenos envolvendo pronomes que vêm ocorrendo de maneira concomitante na história do português brasileiro (PB): a realização de objeto direto nulo (ON) de 3ª pessoa e o preenchimento pronominal do sujeito. Realizamos uma pesquisa diacrônica que buscou: (i) verificar se houve aumento de sujeitos pronominais expressos no intervalo de 20 anos em Porto Alegre (RS); (ii) verificar se houve aumento de objetos nulos na retomada anafórica nesse mesmo período, nessa mesma cidade; e (iii) verificar quais traços semântico-discursivos do referente (animacidade, especificidade ou gênero semântico) estão atuando como gatilho para a manifestação do pronome nas ocorrências de sujeito e de objeto direto pronominais. Analisamos dois corpora de língua falada espontânea: o corpus do projeto VARSUL, da década de 1990, e o corpus LinguaPOA, produzido e transcrito entre 2015 e 2018. Também usamos dados do NURC, com base no levantamento de Monteiro (1994). Nossos resultados mostram que houve apenas um leve aumento nas ocorrências de sujeito expresso no período de tempo analisado, o que sinaliza que essa mudança está estável em PB. Da mesma forma, também encontramos apenas um leve aumento de ONs no período, o que parece indicar, igualmente, a estabilização de uma mudança. Com relação ao objetivo (iii), mostramos que a distribuição de sujeitos nulos vs expressos e de objetos nulos vs pronomes plenos pôde (até certo ponto) ser explicada com a hipótese do gênero semântico do antecedente. Para os casos destoantes, deixamos sugestões para análises futuras.
Perlindungan Hukum Terhadap Pemberi Fidusi Dari Penerima Fidusia yang Pailit

Published: July 2019

Keberadaan jaminan atau agunan dalam hal pemberian suatu kredit dianggap merupakan bagian yang penting, walaupun adanya jaminan ini dapat dikatakan sebagai sesuatu yang tidak mutlak. Adanya suatu jaminan merupakan upaya untuk mengurangi resiko yang lebih besar terhadap pemberian suatu kredit tersebut. Debitor seringkali percaya atas penyerahan benda jaminan kepada kreditor. Seorang debitor perlu memperhatikan apakah lembaga pembiayaan tersebut sedang menghadapi masalah hukum, seperti terancam dipailitkan. Yang dimaksud dengan keadaan kepailitan adalah lembaga pembiayaan selaku kreditor dalam perjanjian utang piutang tetapi ia merupakan debitor dalam perjanjian yang lain. Apabila suatu ketika kreditor tersebut jatuh pailit, maka seluruh kekayaan kreditor tersebut masuk dalam boedel pailit. Sedangkan para debitor yang mengikatkan diri pada kreditor tersebut dalam perjanjian utang piutang dengan memberikan suatu jaminan tertentu juga akan merasakan akibatnya. Dalam Pasal 33 UUJF dan Pasal 36 ayat (1) UU KPKPU nampak bahwa terdapat perlindungan bagi debitor terhadap kepailitan kreditor. Dimana debitor pada saat terdapat putusan pernyataan pailit terhadap kreditor dapat meminta kepada kurator mengenai kepastian dari kelanjutan perjanjian kreditnya tersebut.
Proportionality Principle on Online Lending Contract in Indonesia

Published: July 2019

AbstractOnline lending is form of alternative funding resulted from financial technology innovation. Until February 2019 there are 99 financial technology corporations that engaged in lending activity that operated officially, legally, and recognized by Otoritas Jasa Keuangan. However, many problems arise form this innovation in form of online lending. Many consumers became the victims of either illegal or even legal online lending platforms. Started from the paramount loan interest applied in the online lending agreement until the amount of loan that need to be paid did not in accordance to the initial amount of debt, become core of the problems for the online lending consumers that treated unfair and unjustly by the online lending platform organizer. Moreover, online lending contract commonly belonged to the standard clause agreement that have been pre-arranged by one of the contracting parties. This research has purpose to determine the urgency of application of the proportionality principle on online lending contract. This research using doctrinal research method followed by conceptual and statute approaches. This research expected to generates conclusion on the notions of application of proportionality principle on online lending contract that included as standard clause contract in order to distribute contracting parties’ rights and obligations proportionally. Therefore, in future the online lending agreement could generate justice and proportional contract for contracting parties and the substance of the contract can reflect this proportionality principle.

Authors: ÖZDEMİR Lütfiye , BATGA Burcu , UÇAR Bekir
Published: July 2019

Cinsiyet bireyin biyolojik yönünü ifade etmektedir; ancak bireyin içinde doğduğu toplum tarafından cinsiyete yüklenen anlamlar toplumsal cinsiyeti beraberinde getirmektedir. Cinsiyete yüklenen kültürel anlam ve beklentiler, kadın ve erkeğin iş hayatında, evde, siyasette, sokakta nasıl davranması ve hangi rolleri üstlenmesi gerektiğine dair kalıpyargıları da oluşturmaktadır. Toplumsal cinsiyete yüklenen anlamlar özellikle kadınlar açısından bazı eşitsizlikleri ortaya çıkarmaktadır. Üniversite öğrencilerinin toplumsal cinsiyete bakış açılarının kalıpyargılardan uzaklaştırılması gelecek nesiller açısından önem arz etmektedir. Bu noktadan hareketle çalışmanın temel amacı İnönü Üniversitesi İİBF’de birinci sınıfta okuyan öğrencilerin toplumsal cinsiyet algılarını etkileyen demografik niteliklerini belirlemektir. Bu bağlamda araştırmanın evrenini İnönü Üniversitesi İktisadi ve İdari Bilimler Fakültesi’nde birinci sınıfta okuyan öğrenciler oluşturmaktadır. Araştırmada veri toplama aracı olarak 5’li likert ölçeğine göre hazırlanmış "Toplumsal Cinsiyet Rolleri Tutum Ölçeği” ve demografik niteliklerle ilgili soruların yer aldığı bir anket formu kullanılmıştır.  Araştırmada 676 öğrenciden veri elde edilmiş olup bu veriler SPSS programı kullanılarak analiz edilmiştir. Öncelikle ölçeğin güvenilir olup olmadığı Cronbach’s Alpha testi ile değerlendirilmiştir. Öğrencilerin toplumsal cinsiyet algılamalarını etkileyen demografik nitelikleri belirlemek amacıyla Çoklu Regresyon Analizi kullanılmış ve bu analiz sonucunda demografik niteliklerin tamamının hangi oranda toplumsal cinsiyet algısı üzerinde etkili olduğu saptanmıştır.

Production of Calcareous Nannofossil Ooze For Sedimentological Experiments
Authors: Buls Toms , Anderskouv Kresten , Fabricius Ida L. , Friend Patrick L. , Thompson Charlotte E.L. , Stemmerik Lars
Published: July 2019

The notion of fine-grained pelagic carbonates as uniform, monotonous sequences of sediments settled in a quiescent environment has been challenged over the past few decades. Fine-grained pelagic carbonates can undergo substantial reworking after their first deposition, as illustrated by an abundance of sedimentary structures, such as drifts, moats, sediment waves, and channels documented in the Upper Cretaceous Chalk Group of NW Europe. Despite chalk being a major hydrocarbon reservoir rock of the North Sea, surprisingly little is known about the physical behavior of the pelagic carbonate sediment from which the chalk formed—calcareous nannofossil ooze. This poses a serious challenge to the understanding of the depositional system and the properties of facies distribution. Experimental tests, such as those performed in laboratory flumes, are necessary to provide empirical data on this subject. However, the use of modern calcareous nannofossil ooze as an analogue for Cretaceous ooze is associated with a number of disadvantages such as generally higher noncarbonate content and smaller coccolith size of modern oozes. Here, we document a preparation method for the production of calcareous nannofossil ooze for the purpose of physical experiments, based on disaggregation of Upper Cretaceous chalk through repeated freezing and thawing. We further document the textural characteristics of the ooze compared to the original chalk, based on quantitative backscatter scanning electron image analysis, laser diffraction granulometry, and smear slides. The Upper Cretaceous chalk chosen for disaggregation is highly friable due to delicate contact cement and has a low noncarbonate content (< 2 wt %), a high porosity, friability, and good nannofossil and microfossil preservation. These characteristics allowed an effective disaggregation of the chalk matrix into its basic nannofossil and microfossil components, which show good preservation through the disaggregation process. Textural analysis of chalk used for disaggregation and the produced ooze shows no significant differences between the two, thus validating the use of the freeze–thaw method for production of experimental ooze to model the basic depositional behavior of Cretaceous chalk.

The upper reservoir zone of the Lower Cretaceous Kharaib Formation (46–54 m thick in the studied wells) is regarded as the upper portion of a third-order depositional sequence comprising higher-order cycles. Whereas the third-order sequence interpretation is clearly supported by the upward-shoaling trend of the reservoir zone, relationships defining the component cycles have not previously been documented and are the focus of the present study. Core descriptions from four wells in a single oilfield reveal little evidence of facies changes or trends of facies patterns indicative of high-frequency depositional cycles. Cycle boundaries could possibly be represented by the repetitive pattern of coarse beds (rudstone and floatstone) 0.1–2 m thick, commonly having sharp basal contacts and gradational upper contacts with enclosing packstone to wackestone. Because the coarse beds do not appear correlative between wells, however, we prefer the alternative interpretation that they reflect episodic storm events which locally redistributed detritus, sourced from a patchwork of low-relief lithosomes, across the flat surface of the epeiric Kharaib platform–lagoon. Although the existence of high-order eustatic fluctuations during upper Kharaib deposition is well established, low-amplitude variations in water depth may not have touched down on the sea floor to significantly affect sediment textures in contrast with the dominant storm signal.

Reservoir sub-zones used for production operations, but previously suggested to be fourth-order parasequence sets, are defined by dips in porosity-log profiles, reflecting thin (approximately 1 m) intervals of increased stylolite frequency. These boundaries are thus diagenetic in character, but their correlation over tens to hundreds of kilometers indicates an underlying depositional control. We suggest that the link between sea level and diagenesis is depositional-clay content, which facilitates stylolitic dissolution. Profiles of bulk-rock alumina analyses in the studied cores show subtle indications of higher clay content at the sub-zone tops. Much greater clay peaks mark the third-order sequence boundaries, resulting in the “dense” (very low porosity) zones above and below the studied reservoir zone and the increased stylolite frequency in the upper and lower several meters of the zone. Possible factors promoting clay influx across a carbonate shelf during falls in sea level include increased stream gradients and more humid climate.
Landslide Interpretation of the Northeast Flank of Kohala Volcano, Hawaii
Authors: Bishop Kim M.
Published: July 2019

The Hawaiian Island volcanic edifices have shed at least 15 giant submarine landslides, each classified as either a slump or debris avalanche. Controversy exists regarding the number, size, and type of landslides on the northeast flank of Kohala Volcano. This study provides a new interpretation for the Kohala flank based on contour and balanced cross-section analysis. Specifically, contours indicate that there is a landslide extending from the summit to the coast between Pololu and Waipio Valleys. The contour evidence also shows that the slide plane is planar and dips less steeply than the topographic slope. Balanced cross sections show the slide plane to be approximately 950 m deep immediately downhill from the zone of depletion, and the slide plane presumably reaches the surface at the base of the coastal cliffs on the northeast coast of Kohala mountain. The lower part of the landslide once extended from the coast to approximately 10 km offshore, but this portion now has been completely removed, apparently as a debris avalanche. Removal of this distal landslide mass created a 200 to 450 m headwall that is now topographically represented by sea cliffs. This newly identified slide/debris avalanche is informally named the “Kohala landslide.” Based on cross-cutting relations of landslide faults with Hawi series lava flows, the upper slide part of the landslide moved sometime between 270 and 60 ka. The age of the lower, debris avalanche part is even less certain and depends on whether canyons cut in the seafloor after the avalanche movement were eroded in the subaerial or submarine environment.

Published: July 2019

Serious soil erosion can endanger human survival and sustainable development. Therefore, simple and highly efficient soil stabilizers that can be used to treat loess soil, which has poor water stability and easily disintegrates, are a topic of concern for researchers. In this work, a biomass-based polymeric soil stabilizer (CXZ) was prepared using a “green” strategy with polymerization of carboxymethyl cellulose and xanthan gum. A direct shear test, unconfined compressive strength properties, water stability, and erosion resistance were systematically investigated to test the stabilization performance. The stabilizer agglomerated small loess particles into large aggregates through “coating” and “weaving” effects to increase the cohesion, water stability, and erosion resistance significantly, as demonstrated by Fourier transform infrared spectroscopy and scanning electron microscope. Furthermore, in a 30-day growth experiment, the number of alfalfa plants and the plant height in stabilized loess both increased with the increase in CXZ stabilizer concentration. This work provides insight into a novel biomass-based soil-curing agent, broadening its applications in loess remediation and soil erosion control.

Published: July 2019

Anchored retaining walls are restraining walls constructed using anchors to achieve the highest stiffness possible within economic considerations. Anchor length estimation has an important role in the study of the stability of anchored retaining walls. The purpose of this study was to investigate the anchor length using different proposed failure models and Kranz's classic model. In addition, several parametric studies were conducted to find reliable results in the stability analysis of retaining anchored walls with the aim of obtaining stable and shorter anchor lengths. A numerical study was carried out using Geo4 and Plaxis 8.6 software on the same standard profile as analytically studied so as to validate the proposed mechanical models. The failure models proposed in this work are shown to be a useful tool for obtaining stable and shorter anchor lengths for anchored retaining walls.
Application of Hydraulic Flushing in Coal Seams To Reduce Hazardous Outbursts in the Mengjin Mine, China

Published: July 2019

Hydraulic fracturing and waterjet slotting fracturing have been demonstrated to be effective in creating artificial fractures and stimulating gas production in hard coal seams. However, these methods are inefficient for soft-outburst coal seams because these created fractures are short and easy to close. To eliminate the outburst risk of soft coals, a novel enhanced coalbed methane under-panel cross-strata drainage technique via hydraulic flushing was proposed in this work. The hydraulic flushing effects of boreholes of different sizes in the coal seam were also pre-evaluated by a simulation approach. The modeling results indicate that as the radius of the borehole increases, the plastic and stress-decreasing zone expands. A field test was also conducted in the Minjin mine, China, that investigated the gas pressure variation between three monitoring boreholes at different distances from a hydraulic flushing borehole. Test results indicate that the effective influence radius of gas extraction is approximately 5.5 m. Based on the results of the field test and borehole camera observation, the unloaded coal quantity and the average diameter of the boreholes were estimated to be 8.0 t and 942 mm, respectively. The borehole diameter expanded up to 10 times larger than its original size. The average gas extraction concentration and gas flow rate increased by approximately 2 and 3.5 times, respectively, demonstrating the effectiveness of the proposed hydraulic flushing in improving the gas extraction efficiency. The hydraulic flushing technique therefore is proved to be efficient in eliminating the outburst risk of coal and reducing greenhouse gas emissions.
Optimizing Digital Elevation Model Resolution Inputs and Number of Stream Gauges in Geographic Information System Predictions of Flood Inundation: a Case Study Along the Illinois River, Usa

Published: July 2019

Spatial analysis using Geographic Information Systems (GISs) is evaluated for its ability to predict the potential hazard of a flood event in the Illinois River region in the state of Illinois. The data employed in the analysis are available to the public from trusted organizations such as the Illinois State Geological Survey and the U.S. Geological Survey. Since available GIS data may be limited for flood risk modeling in some parts of the world, the purposes of this study are to examine the use of spatial analysis in a GIS to determine flood inundation risk and to produce an accurate flood inundation vulnerability map employing the least amount of data. This study concentrates on areas that have stream gauge data with definable flood stage(s) and utilizes the inverse distance weighted interpolation method on different digital elevation models (DEMs) with different spatial resolutions (1 m, 10 m, and 30 m) to determine the extent of flooding over the study area. Resulting maps created for the Illinois River region yielded about 80 percent agreement with the effects of an actual flood event on the Illinois River near Peoria, IL, on April 23, 2013. A four-gauge distribution scenario using a 10-m DEM produced the most accurate results, but all scenarios generated reasonable flood simulation. Thus, we speculate that it is possible to create a flood prediction map with a reasonable amount of accuracy using only two initial input data layers: stream gauges and a DEM.
Qualitative Rock Wedge Stability Evaluation Performed For Foundation of Green Peter Dam, Oregon
Authors: Loar Todd N.
Published: July 2019

Green Peter Dam is a concrete gravity structure located in west-central Oregon on the Middle Santiam River within the Willamette Valley Basin. A risk assessment for the project identified continuous and adversely oriented low-angled shear zones underlying portions of the foundation that could potentially facilitate sliding instability of one or more monoliths during earthquake loading. Conceptually, a potential foundation rock wedge could be formed with a shear zone as its sliding surface and joints as the side planes. This wedge, which would otherwise be stable under static conditions, could feasibly be displaced and/or shifted during seismic ground shaking, resulting in significant structural damage and/or breach of the dam. A qualitative evaluation was performed to characterize the geomechanical conditions and geometry of movement (i.e., kinematics) of the dam-foundation system associated with rock wedges. The study revealed that wedges could indeed be formed by adversely oriented and intersecting rock mass discontinuities. The qualitative evaluation concluded that the displacement geometry and geologic conditions in the foundation collectively suggest that the wedges would likely be stable under even large probabilistic seismic loading. While no concrete dams are known to have failed due to seismic loading, an increased knowledge of higher seismicity in the Pacific Northwest region warranted a careful evaluation to ensure that the risks of foundation rock wedge deformation are well characterized, and that our level of confidence in the available data is acceptable to better constrain the potential risk posed by this failure mode. This paper summarizes the background, findings, and results of the preliminary and qualitative dam-foundation system stability evaluation that was performed for Green Peter Dam.
Lessons Learned from Usace Seepage Barrier Wall Construction: Wolf Creek To Present
Authors: Hlepas Georgette , Bateman Vanessa
Published: July 2019

The U.S. Army Corps of Engineers (USACE) maintains a lessons-learned goal for all major projects to capture knowledge gained. The focus of the formal lessons-learned process is to share knowledge and experience nationwide improving USACE contracting methodologies, reducing overall costs, and improving designs. This continuous improvement can be seen in the evolution of USACE barrier wall construction designs and contracting methods. From the first Wolf Creek Dam barrier wall installed in the 1970s to the more recent Bolivar and East Branch Dam barrier wall projects, documentation and sharing of lessons learned in areas such as grouting, data management, and quality assurance procedures have increased the efficiency and effectiveness of barrier wall designs, monitoring, and contract specifications. Contractual philosophy, use of pre-grouting treatment, verification methods, and data management processes have all changed due to lessons learned and have enabled the USACE to improve the overall end product of barrier wall projects.
