An Update of Studies of the Bootheel Lineament in the New Madrid Seismic Zone, Southeastern Missouri and Northeastern Arkansas
Authors: Schweig Eugene S. , Marple Ronald T. , Li Yong
Published: July 2019

Five trenches across the Bootheel lineament, a possible surface expression of one of the coseismic faults of the great New Madrid earthquakes of 1811 and 1812, indicate that ground failure took place along this 135-km-long feature, probably in 1811 or 1812. The morphology and en echelon pattern of the north-northeast-trending lineament are suggestive of strike-slip displacement on a fault. Three trenches cross portions of the lineament along which liquefied sand was injected. Vertically displaced strata were observed in two of these trenches, but the displacement could be due to collapse caused by the removal of liquefied sand from below. Shear zones exposed in two other trenches do not appear to be directly related to liquefaction and may represent near-surface deformation associated with deeper deformation along potentially seismogenic structures.
Assessment of the Style and Timing of Surficial Deformation Along the Central Reelfoot Scarp, Lake County, Tennessee
Authors: Kelson Keith I. , VanArsdale Roy B. , Simpson Gary D. , Lettis William R.
Published: July 2019

Stratigraphic and structural relations exposed in a 90-m-long trench across the Reelfoot scarp in the central New Madrid Seismic Zone (NMSZ) provide data to assess the style and timing of late Holocene tectonic surficial deformation in the central NMSZ. Near-surface deposits exposed in the trench include natural levee, overbank, colluvial, and liquefaction-related deposits. The levee deposits consist of fine-grained, cross-bedded sands and silty sands and are overlain by clayey overbank and scarp-derived colluvial deposits. Liquefaction-related features include sand dikes and sills that intrude into the levee and overbank deposits, and a possible older extrusive sand deposit. Charcoal and archaeological artifacts from a deposit inset into and overlying the levee deposits suggest that the levee deposits are older than about A.D. 800 to 900. Charcoal from the overbank deposits yielded an age estimate of cal. A.D. 1310 ± 90; charcoal from the overlying colluvial deposits yielded an age estimate of cal. A.D. 1540 ± 90.

Distinct marker beds within the levee deposits define a broad monocline that parallels the ground surface and exhibits more than 5 m of down-to-the-east vertical separation. This fold consists, in part, of four smaller-scale flexures each having amplitudes of about 1 m. Associated with these flexures are numerous west-dipping normal faults that have a total net vertical separation of about 0.4 m in a down-to-the-west sense, which is opposite in sense to that exhibited by the scarp and the silty marker beds. We interpret that these faults are related to extension in the crest of the monocline, and that the monocline represents deformation above a west-dipping reverse fault that reaches or approaches the ground surface east of the trench and the base of the scarp. At the trench site, this interpretation places the surface projection of the fault near the western margin of Reelfoot Lake.

Stratigraphic relations exposed in the trench and several shallow boreholes permit identification of at least one and possibly three late Holocene earthquakes. Stratigraphic relations and age-estimates best support the interpretation that the unweathered liquefaction related features exposed in the trench are a result of the 1811–12 earthquakes, and that the scarp-derived colluvial deposits are a result of a prior event. Radiocarbon analyses show that this penultimate event occurred between about A.D. 1310 and A.D. 1540. Stratigraphic evidence of a third event prior to about A.D. 900 is present but equivocal. Given that the most-recent event occurred in A.D. 1812, we estimate that the time between the two most-recent earthquakes large enough to produce liquefaction and/or surface deformation was about 200 to 600 years.
A Test of Paleomagnetism as a Correlation and Dating Technique in the New Madrid Seismic Zone
Authors: Salyards Stephen L.
Published: July 2019

In order to assess the use of paleomagnetic directions of liquefied sands for correlating and dating paleoseismic events, I studied historic liquefaction deposits in the New Madrid seismic zone to verify their ability to record the ambient geomagnetic field direction at the time of liquefaction. Erupted sand from the 1811–1812 New Madrid events are shown to have a remanent magnetic direction in agreement with the field direction recorded in St. Louis in 1819. There is a large variation in the magnetic quality between two adjacent erupted sand layers. These beds show identical magnetic composition and sand grain-size. Lacking a magnetic explanation for their differing behavior, turbulent forces or deformation causing signal degradation during reliquefaction are the preferred explanation. A similar explanation is also suggested for the poor magnetic quality of an injected dike that is coarser-grained, but magnetically identical to the erupted sands.
Minimum Magnitude of Completeness and Rates of Seismicity in the New Madrid Region
Authors: Hass Lotte , Ellis Michael , Rydelek Paul A.
Published: July 2019

We apply the Schuster test to an augmented Central Mississippi Valley (CMV) seismic catalog to determine the minimum magnitude of completeness (MMC). We test the null hypothesis that the events in the catalog are distributed as a Poissonian process at a period of 24 hours. The test is based, in part, on the assumption that event detection is modulated by differences between day and night noise. We tested different temporal portions of the catalog corresponding to the whole catalog, 1974 – 1990; the period of network improvement in 1980 – 1987; and post-1987. The minimum magnitude of completeness between 1980 and 1987 is 1.8 within the region reported in the CMV Earthquake Bulletin. The catalog shows anomalous distribution after 1987, which may be related to a combination of mistaken identification of blasts as earthquakes and changes in network personnel.

A significant (better than 95% confidence) increase in the rate of seismicity above magnitude 2.0 occurred in the central New Madrid seismic zone in 1981, followed by the Arkansas swarm less than a year later and by a significant rate increase in the enveloping region less than two years later. A significant rate decrease occurred in the whole region in June 1987, although the anomalous nature of the post-1987 catalog makes this change suspect. We suggest that the early rate increase is caused by a change in local (New Madrid) fault conditions, rather than a change in far-field conditions, because the rate increase appears first in the central region.
Tectonic Deformation in the New Madrid Seismic Zone: Inferences from Boundary Element Modeling
Authors: Gomberg J. S.
Published: July 2019

The lack of instrumental recordings and of obvious fault scarps associated with the 1811–1812 New Madrid earthquakes necessitates examination of more subtle indicators of the geometry and type of faulting responsible for these events. Morphologic and geologic features and the distribution of modern seismicity are used to infer the number, strike, length, width, type of faulting (strike- or dip-slip), and spatial variability of slip for the major faults in the New Madrid Seismic Zone (NMSZ). This is accomplished through two-dimensional boundary-element modeling of the strain field arising from slip on hypothetical faults that is driven by either coseismic or uniform regional strains. Tectonic deformation is reflected in the seismicity and in morphologic and geologic features including (1) the Lake County uplift, (2) Reelfoot Lake, (3) the deformed rocks of the Blytheville arch, and (4) the St. Francis Sunk Lands. Many of these features can be qualitatively explained as resulting from tectonic deformation due to slip on two left-stepping right-lateral strike-slip faults that are coincident with the northeast-trending zones of seismicity and the Blytheville arch. The morphology appears to be, at least in part, a consequence of major earthquakes that rupture these faults. The locations of the 1811–1812 and largest post-1812 earthquakes and the models are consistent with a process in which the 1811–1812 earthquakes relieved accumulated regional shear strain causing the greatest post-1812 shear strains to exist at the ends of the fault zone. Modeling results also suggest that the numerous small earthquakes in the NMSZ are not aftershocks of the 1811–1812 earthquakes but instead represent continuous localized adjustments to a uniform regional strain field. The Bootheel lineament does not appear to be significant in the shaping the morphology, geologic structure, and pattern of seismicity of the NMSZ. The inferred length of the 1811–1812 earthquake ruptures suggest that their sizes may have been overestimated. Model predicted subsidence within the St. Francis Sunk Lands suggests that tectonic deformation may also influence alluvial processes in the NMSZ.
Tectonic Signal in Baldcypress Trees at Reelfoot Lake, Tennessee
Authors: Stahle David W. , VanArsdale Roy B. , Cleaveland Malcolm K.
Published: July 2019

Tree-ring analyses of baldcypress (Taxodium distichum) from Reelfoot Lake, Tennessee, support historical accounts that the lake formed during the great New Madrid earthquakes of 1811–1812. Due to ground subsidence and permanent flooding all of the bottomland hardwood trees within the impounded area were killed. However, many water tolerant baldcypress survived, and hundreds of 200 to 800 year old baldcypress outline the positions of former stream channels drowned by the subsidence. Dendrochronological analyses of multiple cores from 21 baldcypress in the lake reveal several pronounced growth responses to the 1811–1812 earthquakes. These responses include a great surge in radial growth during the decade following the earthquakes and a permanent reduction in wood density beginning in 1812. These and other growth responses to the 1811–1812 earthquakes may allow detection and dating of other large earthquakes in the Reelfoot basin during the late Holocene and may help date the formation of other suspected sunk lands in the New Madrid seismic zone.
Implementation of Seismic Hazard Mitigation in the Central United States: The Policy - Setting Role of the States
Authors: Olshansky Robert B.
Published: July 2019

This research examines the potential for state-level seismic hazard mitigation policies in the seven member states of the Central United States Earthquake Consortium. The federal government requires mitigation to be a significant component of emergency preparedness activities, but such activities are only beginning to be implemented in the Central U.S. This paper describes current activities by the seven states and identifies future needs. The research found that awareness and preparedness activities have increased markedly over the past few years, five of the states now have state seismic building code requirements, several states have active seismic advisory councils, and some states are using innovative funding methods to finance seismic zonation mapping. The greatest future needs are to continue these efforts as well as initiate programs for existing building hazards and non-structural hazards. Programs should emphasize critical facilities.
Analysis of Shallow Microearthquakes in the South Sebec Seismic Zone, Maine, 1989–1990
Authors: Doll William E. , Rea Carol D. , Ebel John E. , Craven Sandra J. , Cipar John J.
Published: July 2019

Fifteen years of regional monitoring by the New England Seismic Network indicated a locally high level of seismicity near South Sebec, between the towns of Milo and Dover-Foxcroft in central Maine. Most of the events were located in a diffuse zone south of the distinctive, ENE trending Harriman Pond Fault (HPF) which is indicated by brittle deformation in outcrop and is represented as a depression in topographic maps and satellite images. A portable network consisting of both digital and analog instruments was deployed during the summers of 1989 and 1990 in order to characterize the pattern of the microearthquakes and to determine high-resolution epicenters, depths, and fault plane solutions. Seventy-three events were detected during the experiment, of which 28 could be located. Many of the events south of the fault lie along a NNW trending line which has no major expression in the surface geology. Only, a few of the events are subparallel to the HPF. The first motion data were insufficient for the determination of any fault plane solutions.
Seismotectonics of the 1987–1988 Lakeside, Utah, Earthquakes
Authors: Pechmann James C. , Arabasz Walter J. , Brown Ethan D.
Published: July 2019

From September 1987 through March 1988, an earthquake sequence which induded shocks of ML 4.8 and 4.7 on September 25 and October 26, respectively, and a total of 8 moderate-sized events of ML ≥ 3.8, occurred in NW Utah beneath a desert basin west of the Great Salt Lake (center of activity: 41° 12.0′ N, 113° 10.5′ W). Wood-Anderson seismograms indicate nearly identical magnitudes for the two largest earthquakes but a factor of two to five larger seismic moment for the first. Significant aspects of the 1987–1988 sequence induded: foreshock activity, proximity (epicentral distance, Δ, of 7 to 12 km) to a major pumping facility completed in early 1987 to lower the level of the Great Salt Lake, an unambiguous strike-slip focal mechanism for the ML 4.8 mainshock, and the lack of a clear association with late Quaternary surface faults.

Despite constraints on accessibility to the epicentral area, the stations of the regional seismic network (Δ ≥ 60 km) were supplemented with local stations—initially four portable seismographs and later up to four telemetered stations (2 ≤ Δ ≤ 27 km) that operated continuously from October 7, 1987, through March 1988. Well-located aftershock foci form a 6-by-6-km zone between 6 and 12 km depth which is steeply dipping and trends SSE, parallel to the right-lateral nodal plane of the mainshock focal mechanism. Despite coincidental timing and proximity of the earthquakes to major pumping activity at the surface, the case for induced seismicity related to the pumping is weak.

Purpose of the study. Analyze the parameters of the interaction between the left ventricle and the arterial system in patients with chronic forms of coronary heart disease and to identify relationships with levels of proadrenomedullin (MR‑proADM) and N‑terminal precursor of the brain natriuretic peptide B (NT‑proBNP).Materials and methods.240 patients with chronic forms of coronary heart disease (median – 55,9 [43; 63] years) and Q‑forming myocardial infarction in the past were examined. Of these, 110 patients with myocardial infarction and preserved lef ventricular ejection fraction and 130 patients with ischemic cardiomyopathy. All patients were calculated parameters of lef ventricular‑arterial interaction and the determination in blood serum levels of MR‑proADM and NT‑proBNP.Results.In patients with ischemic cardiomyopathy, an increase in the lef ventricular‑arterial interaction index was detected (2,51 [1,18; 5,00]), which reﬂects a decrease in the functional abilities and efficiency of the heart. In patients with myocardial infarction and a preserved left ventricular ejection fraction, this indicator was in the range of normal values (0,78 [0,55; 1,07]), which indicates an eﬀective cardiac work. A study of MR‑proADM and NT‑proBNP levels demonstrated an increase in both groups (1,72 [1,56; 1,98] nmol/l and 779,3 [473; 2193] pg/ml in the group of patients with ischemic cardiomyopathy; 0,89 [0,51; 1,35] nmol/l and 246 [118; 430] pg/ml in the group of patients with myocardial infarction and preserved left ventricular ejection fraction), and the correlation analysis with left ventricular‑arterial coupling interaction parameters allowed identify statistically significant connections (in the group of patients with ischemic cardiomyopathy: with the level of MR‑proADM ‑ r=0,67, p=0,006, with the level of NT‑proBNP ‑ r=0,78, p<0,001; in the group of patients with myocardial infarction and preserved left ventricular ejection fraction: with MR‑proADM level ‑ r=‑0,52, p=0,024, with NT‑proBNP level ‑ r =‑0,38, p=0,037).Conclusion.The findings suggest a pathogenetic association between the biomarkers under study and the parameters of left ventricular‑arterial coupling interaction.

Published: July 2019

Tradicionalmente, os retificadores do tipo Boost operando no modo de condução descontínua (MCD) não usam controle de corrente e operam com razão cíclica constante, mas apresentam uma distorção harmônica significativa devido à presença de uma componente de 3ª harmônica. O presente artigo equaciona matematicamente o problema e propõe o uso de uma técnica de modulação que corrige a razão cíclica durante o período da rede e, assim, elimina significativamente a distorção harmônica da corrente, sem adicionar sensores de corrente. A técnica de modulação utilizada já foi apresentada na literatura, no entanto, este artigo demonstra um maior detalhamento matemático da estratégia e propõe uma metodologia para determinar o índice de modulação ótimo. Adicionalmente, propõe-se também uma alternativa para tornar a técnica menos susceptível às variações da tensão de entrada. De modo a validar o estudo teórico, construiu-se um protótipo de 500 W do retificador Boost bridgeless modificado, com tensão eficaz de entrada de 220 V, tensão de saída de 450 V e frequência de comutação de 58,6 kHz. Resultados experimentais apresentaram uma melhoria na distorção harmônica total de 22,17% para 4,88% e no fator de potência de 0,977 para 0,996, ambos em carga nominal.
Identities with Historical Regions – are they Adapting to Modern Administrative Division? The Case of Ukraine
Authors: Gnatiuk Oleksiy , Melnychuk Anatoliy
Published: July 2019

Historical regions remain the most common basis for the formation or promotion of regional identities in Europe. However, regions and regional identities are in the process of constant formation and can change significantly in line with new conditions. In this paper we focused on the changes of the spatial spread of identities with historical regions in Ukraine in comparison to the initial boundaries of those. The results show that identities with historical regions are markedly adapting to modern administrative boundaries. At the same time, the symbolic value of historical regions constitutes an essential element of identity building in contemporary administrative regions.
RESOURCE-EFFICIENT METHODS FOR PREDICTING AND SELECTING HEAT-RESISTANT ALLOYS
Authors: Evdokimov V.B. , Artamonov A.A. , Plotnikov E.V. , Konstantinova N.A.
Published: July 2019

The power plant resource efficiency is largely dependent on heat-resistant alloys and is limited by the standard turbine operating temperature, which is slightly greater than 1000°C. These temperature limits are dependent on the characteristics of the heat-resistant alloys used in power plants. The current research aimed to discover new heat-resistant alloys using computer-based models to simulate the various properties of such materials. The first-principle methods were initially used in this study. These methods can determine the most important properties of alloys with a high degree of accuracy. This study presented an overview of the software used for first-principle simulation. Using RuAl as the demonstration alloy in this study, we provided step-by-step instructions on how to effectively study the properties of the heat-resistant alloys. Using the first-principle methods, the phonon spectrum and density of the phonon states of B2 RuAl were assessed. We use the parameters of the phonon spectrum to calculate the Grüneisen constant, volume coefficient of thermal expansion, Debye temperature, and temperature dependence of the heat capacity to estimate the melting temperature. Based on the RuAl alloy, the bulk moduli of the elasticity and equilibrium values of lattice parameters were calculated. The simulated results showed good agreement with the experimental data. The calculated parameters of RuAl were compared with those of the NiAl heat-resistant alloy. Using these results, we presented a method for selecting an alloy based on the replacement of ruthenium with nickel in the RuAl alloy. Selection was performed by analyzing the bulk modulus of elasticity and the electron structure of the Ru(Ni)Al alloy.
COMPARISON OF GLOW, ARC, AND MAGNETRON DIRECT CURRENT DISCHARGES
Authors: Abrahamyan A.S. , Mkrtchyan A.H. , Chilingaryan R.Yu.
Published: July 2019

Glow discharge (GD) in a tube, arc discharge (AD) without cathode heating from an external source, and magnetron discharge (MD) in a planar magnetron are compared. In each of the discharges, characteristic areas are distinguished. In MD, electrons trapped in the near-cathode region are not directly involved in ionization processes, but “wake” acceleration of slow ions by electrons that move along Larmor orbits is possible, which gives additional energy to ions moving toward the cathode. In GD in the near-cathode region, the average energy of the ejected electrons is on the order of several electron volts, and the energy of the ions and neutrals is less than 0.1 eV. In MD in the near-cathode region, the average energy of knocked-out electrons, ions, and neutrals is on the order of tens of electron volts. The differential resistance of GD is negative, that of AD is usually negative, and that of MD is positive. The energy of ions in the magnetron plasma can be greater than that of electrons, which gives new possibilities for acoustoplasma control of MD and the creation of appropriate instruments and devices.
Agrupamentos fonéticos da vogal média anterior /e/ em posição pretônica no Atlas Linguístico de Rondônia (ALiRo)

Published: July 2019

Este estudo trata da análise e cartografia da variação da vogal média pretônica /e/ a partir do corpus do Projeto Atlas Linguístico de Rondônia – ALiRO. O trabalho segue a orientação teórico-metodológica da Dialetologia Pluridimensional e Relacional (RADTKE; THUN, 1996), da Geossociolinguística (RAZKY, 1998; 2004; 2010), da Sociolinguística Quantitativa (GUY; ZILLER, 2007) e da noção de agrupamento (RAZKY, 2013; RAZKY; GUEDES, 2015; RAZKY; COIMBRA; COSTA, 2017). Foram analisados dados de 62 colaboradores distribuídos entre os 16 pontos de inquérito que compõem a rede de pontos do ALiRO, os quais foram estratificados conforme os grupos de fatores considerados no referido projeto, quais sejam: faixa etária (dois informantes de 18 a 30 anos e dois de 50 a 65 anos); sexo (dois homens e duas mulheres); e localidade (microrregiões e municípios). Em Porto Velho, capital, tem-se 8 colaboradores estratificados em sexo (quatro homens e quatro mulheres), faixa etária (quatro informantes de 18 a 30 anos e quatro informantes de 50 a 65 anos) e escolaridade (quatro até o ensino médio e quatro com nível superior). Foram investigadas três realizações da vogal média pretônica anterior /e/, a saber: abaixamento, alçamento e manutenção. Os resultados mostram que o fator diageracional influencia o abaixamento e a manutenção da vogal /e/, uma vez que o abaixamento foi mais recorrente na fala dos informantes mais velhos, ao passo que a manutenção predominou na fala dos mais jovens. O estudo demonstra, ainda, que há quatro tipos de agrupamentos fonéticos no território rondoniense, os quais corroboram com a noção de agrupamento adotada nesta pesquisa.

O presente artigo analisa o uso cotidiano e amplamente difundido do “português de arremedo” entre brasileiros. Adota-se o termo português de arremedo em referência à prática linguística na qual uma pessoa replica palavras e expressões de variedades não padrão, à margem do português padrão, com o intento de fazer graça. Para tanto, utiliza-se uma análise qualitativa a partir de dados que são profusamente compartilhados online através de aplicativos de mensagens, blogs, redes sociais, além da mídia tradicional. Com base em conceitos e pesquisas da sociolinguística e antropologia linguística, busca-se mostrar que (1) o português de arremedo produz uma falsa sensação de inocuidade; (2) a pessoa que produz o português de arremedo — ou seja a pessoa que arremeda o português dos falantes das variedades não padrão, i.e. marginalizadas — ocupa um lugar de fala que é resultado de desigualdade linguística e social; e (3) a pessoa que produz o português de arremedo é, em parte, responsável pela reprodução dessa desigualdade.
KAJIAN KEBIJAKAN MAKROPRUDENSIAL LOAN TO VALUE RATIO DALAM PENGENDALIAN KREDIT PEMILIKAN RUMAH
Authors: Muthia Azka
Published: July 2019

Housing credit in Indonesia has high growth from 2011. This growth could become excessive growth and cause housing bubble. Therefore, the government implement Loan To Value (LTV) to control mortgages. However, growth of housing credit is still fluctuating and slowing down when the government loosening LTV policy. This condition become the reasons to evaluate the success of LTV in Indonesia. The results using Hodrick Prescott (HP) filter method identified that housing credit several times experienced excessive growth and with Generalized Linear Autoregressive Moving Average (GLARMA) method shows that housing credit to GDP ratio is influenced by previous month and not influenced by LTV policy.

AbstractMaking transactions can get a lot of profit, then there are several ways, one of which is in the form of investing. To make investments can be done by individuals or a person entity that has excess funds or is often called a company securities. Regulations regarding risk in Municipal Bonds are not the same as arrangements in corporate bonds and corporate bonds themselves, basically payment of Municipal Bonds made by this Regional Government comes from funds from the utilization / use of infrastructure built from publishing the regional bonds and reserve funds in the APBD must be allocated to repayment. it is important to research how to regulate and the process of issuing regional bonds. From this background can be drawn formulation of the problem, namely, How to Analyze the regulation and issuance process of Bonds Regions in Indonesia?The results of the formulation of the problem that the author took was that all the rulesrelated to procedures and issuance of municipal bonds is clear and regulated in law -invite, namely Law Number 33 of 2004 concerning Financial Balance between the Central Government and Regional Government, Government Regulation Number 30 In 2011 concerning Regional Loans, Minister of Finance Regulation Number 180 / PMK.07 / 2015 concerning Amendments to Regulation of the Minister of Finance Number 111 / PMK.07 / 2012 concerning Procedures for Issuance and Accountability of Bonds Area. Issuance of bonds can also be done through a public offering.

Through history, particular attention has been paid of the study of the relationship between the energy use and the city structure. Improving energy efficiency in modern agglomerations is the most promising means to mitigate climate change and its impacts. In this current context of globalisation, European Union proposes initiatives and policy targets to rethink the urban development strategies towards the ‘zero energy objectives’. Providing a methodological approach with a simulation district analysis, the present article summarizes how the ‘zero energy’ challenge is analyzed in an existing district (Epinlieu) to articulate the users’ requirements in energy. This study contributes to the scientific discussion of the districts’ urban structure and energy planning by establishing a linkage among the beneficial influence of the KPIs of the districts’ form to increase their energy efficiency and its application in a real case study in Belgium.

The effect of river fronts on oil slick transport has been demonstrated using high resolution forcing models and a fully fledged oil drift model, OpenOil. The model system is used to simulate the 2010 DeepWater Horizon oil spill. Metocean forcing data are taken from the GoM-HYCOM 1/50° ocean model with realistic river input and ECMWF global forecast products of wind and wave parameters with 1/8° resolution. The simulations are initialized from satellite observations of the surface oil patch. OpenOil includes most of the relevant processes, such as emulsification, evaporation, wave entrainment, stranding and droplet formation. The model takes account of the actual oil type and properties, using the ADIOS oil weathering database of NOAA. The effect of using a newly developed parameterization for oil droplet size distribution is studied and compared to a traditional algorithm. Although the algorithms provide different distributions for a single wave breaking event, it is found that the net difference after long simulations is negligible, indicating that the outcome is robust regarding the choice of parameterization. That indicates that the wave entrainment, vertical mixing and re-surfacing mechanisms that are part of OpenOil are more important for determining the final droplet size spectrum than the spectrum prescribed for individual wave breaking events. In both cases, the size of the droplets controls how much oil is present at the surface and hence are subject to wind and Stokes drift. The effect of removing river outflow in the ocean model is investigated in order to showcase effects of river induced fronts on oil spreading. A consistent effect on the amount and location of stranded oil is found, and considerable impact of river induced fronts is seen on the location of the surface oil patch. During a case with large river outflow (May 20-27, 2010), the total amount of stranded oil is reduced by about 50% in the simulation with no river input. The results compares well with satellite observations of the surface oil patch.

We report fabrication of crystalline microresonators of high quality (Q) factors with a controllable wedge angle on lithium niobate on insulator (LNOI). Our technique relies on femtosecond laser assisted chemo-mechanical polish which allows us to achieve ultrahigh surface smoothness as critically demanded by high Q microresonator applications. We show that by refining the polish parameters, Q factors as high as 4.7 × 107 can be obtained and the wedge angle of the LNOI can be continuously tuned from 9° to 51°.

The quality and quantity of cow’s milk produced were determined by the genetic, food, age, milking processing, and the treatment of cattle. The storability of fresh cow's milk tends to be short. Therefore, it is necessary to find ways to extend the life time of fresh cow's milk, one of which is by processing fresh cow's milk into other products, such as milk soap bar. The purpose of this study was to determine the appropriate method of milk soap bar production in home industries capacity and to formulate composition of vegetable oils and fresh cow's milk. The milk soap bar obtained then was analyzed in several laboratory tests such as acidity test (pH), moisture content, free alkaline content, and foam stability. Based on the research, it is turned out that the appropriate method of milk soap bar production was the cold process. The optimum formula is olive oil (11%), coconut oil (22%), palm oil (22%), fresh cow's milk (33%), and NaOH pellets (12% - equivalent to 9.2 N). The free alkaline content will decrease according the curing time. Simpler economic evaluation obtained that the production cost of milk was Rp.6,711.22/package of 80 grams of milk soap bar. Milk soap bar  is sold for Rp. 7,000.00 will provide 87.96% after-tax of ROI, 11.7 – month of POT, and 65.31% of BEP.

The survey, conducted by the Research Institute for Food, Drugs and Cosmetics –The Council of Indonesian Ulama (MUI) shows that there are still some consumers who pay less attention to the existence of the halal label on cosmetics products, whereas it indicates the halal status of a product. The better understanding of the religion makes Muslim consumers selective in choosing the product to be consumed. This study is aimed at determining the effect of the halal product label of Mustika Ratu cosmetic products on consumer trust in Bandung City. The research sample consists of 115 female Muslims in Bandung who actively use MustikaRatu cosmetic products. The sampling technique in this study is purposive sampling. The data collection was conducted using questionnaires. The data analysis in this research is descriptive and verification analysis using Partial Least Square (PLS) approach with Smart-PLS 3.0. The results of this study illustrate that the halal product label has a positive and significant effect on consumer trust. It is proven from the finding of this research that the existence of halal product label in green and round shape with the writings of halal in Arabic and the Council of Indonesian Ulama, attached to the packaging, affects customer trust.

Published: July 2019

Existen evidencias de un escaso interés hacia las ciencias en el alumnado de la educación obligatoria. Asimismo, está descendiendo la frecuencia del contacto directo con la naturaleza en la niñez y en la adolescencia y el peso de la educación ambiental en el currículo es escaso. Ante estas tendencias, la presente investigación analiza cómo mejorar en la educación secundaria el proceso de enseñanza-aprendizaje de la biodiversidad. Se propone adoptar un enfoque constructivista y aplicar experiencias de aprendizaje basado en problemas, incluyendo prácticas de campo. De esta forma, se pretende aumentar la implicación del alumnado y su aprendizaje significativo, además de crear sinergias con otras materias para la comprensión integral de los aspectos socio-ambientales que regulan la dinámica del entorno.
Quantitative Characterization of Architecture Elements and Their Response To Base-Level Change In A Sandy Braided Fluvial System At A Mountain Front
Authors: Li Shunli , Yu Xinghe , Chen Bintao , Li Shengli
Published: July 2019

The Rockcave Member of the Yungang Formation (Middle Jurassic), in the Datong Basin, China, is a multistory sandstone that is interpreted as a sandy braided fluvial deposit based on grain size, lithofacies, and architectural elements. The depositional setting was the mountain front of the Datong Basin, which was tens of kilometers from the shoreline of a lacustrine basin during the Middle Jurassic. The concept of base level is used to analyze the architectural elements of the braided system obtained from photographic mosaics and high-resolution measurement of six outcrop sections from Yungang Rock Cave. Grain size, lithology, and bounding surfaces together with scale and dimension parameters of the sedimentary structures in various architectural elements were used to quantitatively characterize each group of architectural elements and stratigraphic units. Width/thickness values of trough crossbeds were found to be a fundamental component of the hydrodynamic regimes. During base-level rise the braided fluvial system developed large-scale channel units, bar units, and overbank fills. The relatively high proportion of bar units and overbank fills reflect processes operating during positive accommodation. However, during base-level fall there are a high proportion of small-scale channel units that reflect incision-dominated processes such as channels with low W/T values for trough crossbeds and less common overbank fines.
