Abstract
Two new lignans, 3,4-(10-methoxy-phenylallyl)-9″-((10′-isopropanol-3′,4′-furan)-phenylacetyl)-8″-dioxane-7″-O-β-d-glucopyranoside (1), 3,4-benzolactone-9″-((12′-isopropanol-3′,4′-furan)-phenylbutenone)-8″-dioxane-7″-O-β-d-glucopyranoside (2), and nine known lignan derivatives (3–11) were isolated from the flower buds of Magnolia biondii Pamp. for the first time. Their structures were elucidated by 1D and 2D NMR, UV, IR, and MS data, as well as by comparison with those of the references. Compounds (1–11) were evaluated for their neuroprotective activities against 6-OHDA-induced cell death in SH-SY5Y cells. As a result, compounds 1, 2, and 5 exhibited significant neuroprotective activities with IC50 values in the range of 3.08–6.12 μM.

Abstract
This study focuses on evaluation of degradation aptitude of white rot fungus (Coriolus versicolor) against Indosol Turquoise FBL dye. The outcome of numerous parameters including pH, temperature, carbon sources, nitrogen sources, C/N ratio and effect of dye concentration were studied. Maximum decolorization (99.896%) of Indosol Turquoise FBL was obtained by C. versicolor under optimized conditions. After three days, the maximum dye degradation (98%) was observed at pH 4 and 30 °C. Six carbon sources fructose, glucose, maltose, sucrose, rice bran and wheat bran were used and 96.66% degradation was observed by maltose at its optimum growth concentration (0.1 g/100 mL). Various nitrogen sources were employed for decolorization but ammonium nitrate decolorized dye up to 98.05%. The activity of three different enzymes laccase, Lignin peroxidase (LiP) and Manganese peroxidase (MnP) were calculated. The dead biomass of White rot fungus (WRF) was used for biosorption experiments. Maximum q (36 mg/g) was obtained at pH 2, at 30 °C using 0.05 g biosorbent. An increase in the q value was observed with increase in dye concentration. Freundlich adsorption isotherm and pseudo second order kinetics were followed by the data. It can be concluded that C. versicolor could be an efficient source for degradation of dyes from industrial effluents.

Abstract
In this study, an extremely effective electromembrane extraction (EME) method was developed for the selective extraction of Cu(II) followed by Red-Green-Blue (RGB) detection. The effective parameters optimized for the extraction efficiency of EME include applied voltage, extraction time, supported liquid membrane (SLM) composition, pH of acceptor/donor phases, and stirring rate. Under optimized conditions, Cu(II) was extracted from a 3 mL aqueous donor phase to 8 µL of 100 mM HCl acceptor solution through 1-octanol SLM using an applied voltage of 50 V for 15 min. The proposed method provides a working range of 0.1–0.75 µg·mL−1 with 0.03 µg·mL−1 limit for detection. Finally, the developed technique was applied to different environmental water samples for monitoring environmental pollution. Obtained relative recoveries were within the range of 93–106%. The relative standard deviation (RSD) and enhancement factor (EF) were found to be ≤4.8% and 100 respectively. We hope that this method can be introduced for quantitative determination of Cu(II) as a fast, simple, portable, inexpensive, effective, and precise procedure.

Ground-Motion Duration Prediction Model from Recorded Mexican Interplate and Intermediate-Depth Intraslab Earthquakes
Authors: Jaimes Miguel A. , García-Soto Adrián-David 
Published: November 2020

ABSTRACTPredictive models for ground-motion duration of Mexican subduction interplate and intermediate-depth intraslab earthquakes are presented. The considered sites are rock sites. For the ground-motion duration models, the significant durations for ranges between 5%–75%, 5%–95%, and 2.5%–97.5% of Arias intensity are considered for the analyses. The significant duration predictive models are expressed in terms of magnitude, distance, and focal depth; this last variable is considered only for intraslab earthquakes. A total of 418 and 366 accelerograms obtained from 40 Mexican interplate and 23 intraslab earthquakes, respectively, are used. The applicability of the duration equation for subduction interplate events is restricted to moment magnitudes 5&lt;Mw&lt;8 and distances to the fault surface 17&lt;R&lt;400  km; for intraslab events, it is restricted to 5.2&lt;Mw&lt;8.2, 22&lt;R&lt;400  km, and focal depths 35&lt;HD&lt;75  km. The models are compared against existent models for Mexico and other regions. The analyses and comparisons indicate that using ground-motion duration models accounting for the two types of earthquakes is required and that such models should be developed for specific regions.
Damping Values Derived from Surface-Source, Downhole-Receiver Measurements at 22 Sites in the San Francisco Bay Area of Central California and the San Fernando Valley of Southern California
Authors: Boore David M. , Gibbs James F. , Joyner William B. 
Published: November 2020

AbstractA method discussed in Gibbs, Boore, et al. (1994) was applied to surface-source, downhole-receiver recordings at 22 boreholes, in the San Francisco Bay area in central California and the San Fernando Valley of southern California, to determine the average damping ratio of shear waves over depth intervals ranging from about 10 m to as much as 245 m (at one site), with most maximum depths being between 35 and 90 m. The average damping values range from somewhat less than 1% to almost 8%, with little dependence on grain size for sites in sediments. Surprisingly, the average damping values for sites with average velocities greater than about 450  m/s, including, but not limited to rock sites, are generally larger than for sites with lower average velocities. The combined effect of the higher damping and shorter travel times through the rock columns, however, leads to an effective attenuation that is generally comparable or smaller than for soil sites.

Authors: Cukarso Salshabiyla Naura Almamira , Herbawani Chahya Kharin 
Published: November 2020

Background: The Javanese community is one of the largest ethnic groups in Indonesia. This culture influences people's behaviour in daily life, including maternal care. Some people still believe in traditional myths and practices related to pregnancy. Even it can threaten the pregnancy. Purpose: This systematic review aims to describe the behaviour of people related to practices and beliefs in Javanese culture. Method: This review used a systematic review method. A systematic and relevant search for scientific articles through Google Scholar with a publication period between 2010-2020. Result: There are still many people who obey the traditional beliefss that has no scientific basis. They hope by believing this can make the pregnancy run smoothly and avoid unwanted events. Conclusion: Traditional beliefs and practices have positive and negative impacts on pregnant women. Health workers must provide evidence-based interventions or health education about pregnancy to the community to prevent behaviour that is contrary to health values and can be harmful to the mother and fetus. Information about pregnancy care is not only conveyed to pregnant women but can also be shared with her husband or parents.
Stratigraphic Measures of Reservoir Connectivity and Heterogeneity in Heavy Oil Fields
Authors: Connell Sean David , Laugier Fabien Jean 
Published: November 2020

Abstract
Optimizing reservoir recovery relies on successfully transforming natural geological complexity into functional flow units that can be used to predict reservoir behavior. Stratigraphic connectivity and heterogeneity can be used to identify preferential flow-paths at different scales within a reservoir. Connectivity and heterogeneity are determined using well-established stratigraphic and reservoir-management methods, including amalgamation ratios, reservoir-quality indices, and Lorenz heterogeneities. Lorenz curves have a broad utility for defining permeability–porosity relationships among well-log and model datasets. Stratigraphic Modified Lorenz Plots (SMLP) are useful for defining quality-contribution rates for specific increments of depth to identify potential flow-risk elements. Different measures of reservoir quality (i.e., Reservoir Quality Indices) highlight heterogeneity distributions and identify potentially movable oil within flow units.
Stratigraphic connectivity and heterogeneity concepts can be used to identify flow units, thief zones, baffles, barriers, or depleted regions that may not be obvious from traditional well-log or sand-flag analyses. Connectivity and heterogeneity workflows for porosity, permeability, saturation, and temperature properties are applied to a high-net fluvial reservoir system to illustrate how fine-scale stratigraphic heterogeneities impact flow within a heavy oil field. Although net-to-gross and related property flags are useful for identifying opportunities, subtle variations in sand quality may not be adequately captured by simple sand-flag analyses.
Reservoir facies defined by heterogeneity and connectivity can guide well-path selection and improve predictions of reservoir behavior from field- to pattern-scale. Integrated connectivity and heterogeneity workflows enable opportunity identification for steamflooding and support heat-management plans by providing geologically consistent and objective measurements that can optimize or accelerate resource maturation in new and mature fields.
Ultra Low IFT or Wettability Alteration: What is More Important for Tight Carbonate Recovery
Authors: Zhang Zifan , Azad Madhar S. , Trivedi Japan J. 
Published: November 2020

AbstractRecently, carboxybetaine based zwitterionic surfactants (CnDmCB) have gained attention for surfactant aided recovery processes for unconventional oil-wet reservoirs due to their high salinity tolerance, wettability alteration potential and ultra-low IFT at extremely low concentrations. Several researchers have investigated the dominant recovery mechanisms among the wettability alteration and interfacial tension (IFT) reduction during surfactant flooding in unconventional, tight, oil-wet reservoirs. Most of the previous studies carried out using spontaneous imbibition fail to answer the dominance of prominent mechanisms, especially with respect to time and location.In this paper, these research gaps are addressed through physico-chemical interactions, and microfluidic studies carried out using carboxybetaine based zwitterionic surfactants (CnDmCB). Four zwitterionic surfactants corresponding to tertiary amines with different chain lengths of 12, 14, 16, 18 carbons were synthesized and characterized by 1H NMR. IFT measurements and rock wettability were investigated for wide range of salinities and surfactant concentrations. CnDmCB surfactant based on its ability to alter rock wettability and reduce interfacial tension reduction was selected for representative carbonate microfluidic studies.Experimental results demonstrated the IFT of carboxybetaine surfactants reduced with the increasing carbon chain length except for C18DmCB due to its poor solubilisation in the high saline brine system. The lowest IFT was up to 4*10-3mN/m for surfactant C16DmCB under the concentration of 0.025 wt% with produced high saline brine. However, this formulation called as F1 could change the zeta potential values of limestone only mildly from 3.07 mV to −3.79 mV. F2 and F3 formulations could change zeta potential value from 10.4 mV to −6.22 mV and −8.12 mV respectively. This signifies that higher wettability alteration potential of F3 and F2 when compared with F1 formulation. The IFT of F2 formulation is also ultralow (6.6*10-3mN/m), whereas the IFT of F3 formulation is relatively higher (0.115 mN/m). The observations of microfluidic studies are significant to emphasize that at early time F2 and F3 formulation corresponded to higher imbibition rate than F1 formulation due to its higher ability to alter the rock wettability from oil-wet to water-wet. As the front propagates to far location, F1 with ultra-low IFT begins to outperform F3 by providing better microscopic displacement and quicker front propagation throughout. The amount of residual oil trapped at far location was higher for F3 formulation than F1 due to its higher IFT.The results of the study signify that significant IFT reduction is needed at later stage while good wettability alteration is important during early stage of flooding and therefore this study holds significance in selecting or designing surfactant based fluid formulation for applications in unconventional tight reservoirs.
