Effects of Quartz Precipitation on the Abundance and Preservation of Organic Matter Pores in Cambrian Marine Shale in South China

To evaluate the effects of quartz precipitation on the abundance and preservation of organic matter pores in marine shale reservoirs, the type of authigenic quartz and the source of silica, as well as the corresponding relation of the Lower Cambrian Shuijingtuo Formation shale in South China were investigated. Quartz in the Shuijingtuo shale occurs as four different types: detrital quartz, replacement of biosiliceous debris, euhedral quartz filled in interparticle pores, and microquartz dispersed in a clay matrix. Euhedral quartz (1–5 μm) and matrix-dispersed microquartz (100–400 nm) are found to be the dominant forms of authigenic quartz. The euhedral quartz accumulates along the interparticle pores, and the porous organic matter fills the interior of the space. Microquartz is mainly wrapped in porous organic matter. Two silica sources were revealed: biogenic silica and clay-derived silica. Biogenic Si is most likely the major source for authigenic quartz in the organic-rich (total organic carbon (TOC) > 2.55 wt. %) samples, which accounts for 23–57 wt. % (average 35 wt.%) of the total Si. Based on petrographic observations, we posit that the precipitation of large-sized euhedral quartz in the interparticle pores most likely originated from biogenic silica in the early stage of diagenesis and that the silica for the clay matrix-dispersed microquartz is provided by biogenic silica and clay-derived silica. The observation of SEM images indicates that the precipitation of early diagenetic euhedral quartz in the interparticle pores enhances rock stiffness, and the buttressing effect can protect the organic matter pores from compaction during the late-stage burial diagenesis. In contrast, the precipitation of late diagenetic microquartz in the clay matrix can lead to a reduction in the capacity of the accommodation space to host retained petroleum, consequently leading to a reduction in the development of organic matter pores and the generation of shale gas.
Mathematical Aspects of Subsonic and Transonic Gas Dynamics

By Lipman Bers London : Chapman and Hall Ltd. Pp. xv + 164. Price 62s. In the preface to this, the third volume in Surveys in Applied Mathematics, F. J. Weyl the Director of the Mathematical Sciences Division of the Office of Naval Research gives broadly speaking two aims as the basis for the series. These are (i) the need to make readily available up-to-date results in selected areas of research and (ii) the need to relate contributions from both sides of the iron curtain in order to produce a balanced appreciation of the present state of knowledge in any such area.
Immune Thrombocytopenia Secondary to COVID-19 in a Vitamin B12-Deficient Patient: A Diagnostic Dilemma and Therapeutic Challenge

Immune thrombocytopenia (ITP) caused by infectious and non-infectious conditions has been reported in coronavirus disease 2019 (COVID-19) patients too. Here we present a 64-year-old male patient with post-COVID-19 pneumonia who presented with a gastrointestinal bleed and was found to have severe isolated thrombocytopenia (22,000/cumm) diagnosed as ITP with extensive investigations. He was treated with pulse steroid therapy and later was also given intravenous immunoglobin in view of poor response. The addition of eltrombopag also resulted in a sub-optimal response. He was also having low vitamin B12, and his bone marrow also supported the megaloblastic picture. Hence, injectable cobalamin was added to the regimen, which resulted in a sustained rise in platelet count that reached 78,000/cumm, and the patient got discharged. This shows the possible hindrance to treatment response by concomitant B12 deficiency. Vitamin B12 deficiency is not an uncommon entity and should be tested in those who show no or slow response to thrombocytopenia.
Lorentz Estimates for Weak Solutions of Quasi-linear Parabolic Equations with Singular Divergence-free Drifts

Abstract This paper investigates regularity in Lorentz spaces for weak solutions of a class of divergence form quasi-linear parabolic equations with singular divergence-free drifts. In this class of equations, the principal terms are vector field functions that are measurable in ( $x,t$ )-variable, and nonlinearly dependent on both unknown solutions and their gradients. Interior, local boundary, and global regularity estimates in Lorentz spaces for gradients of weak solutions are established assuming that the solutions are in BMO space, the John–Nirenberg space. The results are even new when the drifts are identically zero, because they do not require solutions to be bounded as in the available literature. In the linear setting, the results of the paper also improve the standard Calderón–Zygmund regularity theory to the critical borderline case. When the principal term in the equation does not depend on the solution as its variable, our results recover and sharpen known available results. The approach is based on the perturbation technique introduced by Caffarelli and Peral together with a “double-scaling parameter” technique and the maximal function free approach introduced by Acerbi and Mingione.
Normal-Fat vs. High-Fat Diets and Olive Oil vs. CLA-Rich Dairy Fat: A Comparative Study of Their Effects on Atherosclerosis in Male Golden Syrian Hamsters

The relationship between milk fat intake (because of its high saturated fatty acid content) and the risk of suffering from cardiovascular diseases remains controversial. Thus, Golden Syrian hamsters were fed two types of fat—sheep milk fat that was rich in rumenic (cis9,trans11-18:2) and vaccenic (trans11-18:1) acids and olive oil—and two doses (a high- or normal-fat diet) for 14 weeks, and markers of lipid metabolism and atherosclerosis evolution were analyzed. The results revealed that the type and percentage of fat affected most plasma biochemical parameters related to lipid metabolism, while only the expression of five (CD36, SR-B1, ACAT, LDLR, and HMG-CoAR) of the studied lipid-metabolism-related genes was affected by these factors. According to aortic histology, when ingested in excess, both fats caused a similar increase in the thickness of fatty streaks, but the high-milk-fat-based diet caused a more atherogenic plasma profile. The compositions of the fats that were used, the results that were obtained, and the scientific literature indicated that the rumenic acid present in milk fat would regulate the expression of genes involved in ROS generation and, thus, protect against LDL oxidation, causing an effect similar to that of olive oil.
A 65-yr Climatology of Unusual Tracks of Tropical Cyclones in the Vicinity of China's Coastal Waters During 1949-2013

AbstractDespite steady improvements in tropical cyclone (TC) track forecasts, it still remains challenging to predict unusual TC tracks (UNTKs), such as the tracks of sharp turning or looping TCs, especially after they move close to coastal waters. In this study, 1059 UNTK events associated with 564 TCs are identified from a total of 1320 TCs, occurring in the vicinity of China’s coastal waters, during the 65-yr period of 1949–2013, using the best track data archived at the China Meteorological Administration/Shanghai Typhoon Institute. These UNTK events are then categorized into seven types: sharp westward turning (169), sharp eastward turning (86), sharp northward turning (223), sharp southward turning (46), looping (153), rotating (199), and zigzagging (183) tracks, based on an improved UNTK classification scheme. Results show significant annual variability of unusual tracking TCs, ranging between 2 and 18 per year, many of which experience more than one UNTK event in the same or different UNTK types d.
CPML PARAMETER OPTIMIZATION IN FDTD MODELING OF IMPULSIVE SOURCE

The convolutional perfectly matched layer (CPML) is currently, perhaps, the most efficient type of absorbing boundary condition in finite difference time domain method (FDTD) modeling of electromagnetic fields. The aim of this paper is to give a more detailed insight into parameter setting and absorption performance of CPML. In case of electromagnetic waves absorption for high-frequency impulsive source modeling, a proper choice of the CPML parameters is substantial. The numerical results show that stretching coefficient affects both absorption efficiency and dispersion. We demonstrate that, in order to eliminate dispersion, the stretching coefficient should be as small as possible. Additionally, the results have shown that a differentiated Gaussian pulse is a better choice than a regular Gaussian pulse in FDTD simulations.
On Gromov's conjecture for uniform contractions

Let ${\mathbb E}^d$ denote the $d$-dimensional Euclidean space. The $r$-ball body generated by a given set in ${\mathbb E}^d$ is the intersection of balls of radius $r$ centered at the points of the given set. In this paper we prove the following Blaschke-Santal\'o-type inequalities for $r$-ball bodies: for all $1\leq k\leq d$ and for any set of given volume in ${\mathbb E}^d$ the $k$-th intrinsic volume of the $r$-ball body generated by the set becomes maximal if the set is a ball. As an application we prove the following. Gromov's conjecture (1987) states that if the centers of a family of $N$ congruent balls in ${\mathbb E}^d$ is contracted, then the volume of the intersection does not decrease. A uniform contraction is a contraction where all the pairwise distances in the first set of centers are larger than all the pairwise distances in the second set of centers, that is, when the pairwise distances of the two sets are separated by some positive real number. The author and M. Nasz\'odi [Discrete Comput. Geom. 60/4 (2018), 967-980] proved Gromov's conjecture as well as its extension to intrinsic volumes for all uniform contractions in ${\mathbb E}^d$, $d>1$ under the condition that $ N\geq \left(1+\sqrt{2}\right)^d$. We give a short proof of this result using the Blaschke-Santal\'o-type inequalities of $r$-ball bodies. Moreover, we prove it under the weaker condition $N\geq \sqrt{\frac{\pi}{2d}} (1+\sqrt{2})^d+1$ for $d\geq 42$. Finally, we prove an analogue result for uniform contractions of unions of congruent balls in ${\mathbb E}^d$, which improves the relevant earlier results.
Do customer knowledge and customer trust in IDIC affect bank customer retention? Evidence from Indonesia

Purpose — The primary focus of this research was to examine the impact of customer knowledge and customer trust in Indonesia Deposit Insurance Corporation (IDIC) on the retention of bank customers in Indonesia.Method — The study employed a cross-sectional design and quantitative survey study. Questionnaires were distributed randomly to respondents via social media. 141 respondents from bank customers in Indonesia have been analyzed. Hypothesis testing is done by multiple linear regression analysis with structural equation modeling and SmartPLS as a statistical tool.Result — The results show that the average bank customer in Indonesia has sufficient knowledge about the role, function, task, and performance of IDIC. However, knowledge needs to be improved because some customers do not understand it well. The results provide empirical evidence that customer knowledge and customer trust in IDIC have positive influence on bank customer retention.Contribution — There is a new concept with the integration of two theories that will benefit future research. The findings contribute to addressing research gaps that have inconsistent results. The findings also contribute to improving customer knowledge and customer trust as a solution to the impact of the COVID-19 pandemic and the global financial crisis. This study supports the G20 in strengthening financial safety nets, where multilateral development banks are encouraged to strengthen their financing systems to face global economic challenges.
Relationships between Extreme Rain Rates and Convective Intensities from the Perspectives of TRMM and WSR-88D Radars

TRMM PR 2A25, version 7 (V7), retrievals of reflectivity Z and rainfall rate R are compared with WSR-88D dual-polarimetric S-band radar data for 28 radars over the southeastern United States after matching their horizontal resolution and sampling. TRMM Ku-band measurements are converted to S-band approximations to more directly compare reflectivity estimates. Rain rates are approximated from WSR-88D data using the CSU–hydrometeor identification rainfall optimization (HIDRO) algorithm. Tropics-wide TRMM retrievals confirm previous findings of a low overlap fraction between extreme convective intensity, as approximated by the maximum 40-dBZ height, and extreme near-surface rain rates. WSR-88D data also confirm this low overlap but show that it is likely higher than TRMM PR retrievals indicate. For maximum 40-dBZ echo heights that extend above the freezing level, mean WSR-88D reflectivities at low levels are approximately 2 dB higher than TRMM PR reflectivities. Higher WSR-88D-retrieved rain rates for a given low-level reflectivity combine with these higher low-level reflectivities for a given maximum 40-dBZ height to produce rain rates that are approximately double those retrieved by the TRMM PR for maximum 40-dBZ heights that extend above the freezing level. TRMM PR path-integrated attenuation, and WSR-88D specific differential phase, differential reflectivity, and hail fraction indicate that the TRMM PR 2A25 V7 algorithm is possibly misidentifying low–midlevel hail and/or graupel as greater attenuating liquid, or vice versa. This misidentification, coupled with underestimation of path-integrated attenuation caused by nonuniform beamfilling and higher rain rates produced by specific differential phase (KDP)–R than Z–R relationships, results in low-biased 2A25 V7 rain rates in intense convection.
A Case of Recurrent Multiple Myeloma as Testicular Plasmacytoma Without Systemic Disease

Plasma cell neoplasms include various conditions ranging from indolent conditions such as monoclonal gammopathy of undetermined significance (MGUS) to more aggressive forms such as multiple myeloma (MM). The World Health Organization classifies plasmacytomas into two types: solitary osseous plasmacytoma (SOP) and extramedullary plasmacytoma (EMP). Most primary EMPs occur in the upper gastrointestinal tract, head and neck, upper respiratory system, central nervous system, lungs, liver, spleen, and kidneys. However, the occurrence of EMP involving the testis site is quite rare. Given the rarity of testicular plasmacytoma, there is no consensus on the standard of treatment for this diagnosis. Most EMP is radiosensitive, with few localized types responding to surgical intervention. Tumor recurrence and disseminated infiltration are treated with adjuvant chemotherapy after radiation or surgery. Our patient has a unique presentation of an individual who developed recurrent myeloma of the testis 12 years after his initial diagnosis of myeloma.
A WEB-BASED ENGLISH INSTRUCTION BLUEPRINT DESIGN: AN APPLICATION OF ESP WRITING COURSE

One among many considerations that should be taken into consideration when moving a conventional face-to-face course to a web-based course is learners' needs, which are transformed into a research-informed blueprint. This study addressed the process of blueprint design resulting from the needs analysis process of design-based research. The objective is to describe the designe d blueprint set for a web-based English Writing course for nursing students in Indonesia. The blueprint consists of designs of learning approach, performance goals, learning tasks and feedback, instructional strategies, and web design modules and interface. The descriptive statistics were used to test 37 items scored by experts of ESP and Writing about the blueprint. The results of Expert Judgments showed that all items obtained mean at the ‘Good’ categories. It means that the blueprint can be used in conducting the next stage, which is website development.
Effect of Abscisic acid on Legume Growth Rate, Seed Development and Protein Profile in Pisum sativum L.

I N THIS work, cultivated pea ( Pisum sativum L. cv. Master B) is used as a legume model crop plant to investigate the effect of abscisic acid (ABA) treatment on seed filling during embryogenesis. This was evaluated by using two exogenously applied concentrations (10& 20 µM) during three stages of seed developments (early, intermediate and late). Phenotypic characterization of the treated plants included measurement of seed / legume length and diameter at full maturation stages after treatment. The expression of major proteins of the treated plants was detected using SDS-PAGE electrophoresis technique. Our data showed a positive effect of ABA when applied at the late stage of seed development. ABA significantly increased legume size and elevated the expression of some major proteins such as convicilin (70-75kDa), vicilin (50, 34kDa) and legumin (40kDa). The impact of these results is further discussed.
Satellite tracking identifies important foraging areas for loggerhead turtles frequenting the Adriatic Sea, Central Mediterranean

The Adriatic Sea is one of the main foraging areas for marine turtles of the Mediterranean Sea, but the specific high-use sites are poorly known, due to the scarceness of satellite tracking data available for juvenile turtles frequenting the area. In the present study, we tracked 8 juvenile and adult loggerhead turtles (Caretta caretta) that were released along the north-western Adriatic coast after a rehabilitation period having been equipped with Argos-linked satellite transmitters. Tracked turtles displayed quite variable movement patterns, but mostly remained in the north-western Adriatic, especially during the summer months. A marked preference for specific coastal sites was revealed in many turtles, that actively moved towards these specific locations when released south of it or having spent the winter away. Pooling these data with those obtained in previous studies on a further 10 turtles, we highlighted the presence of two main high-use areas, north and south of the Po River delta, where future conservation actions may then be focused.
Heating and Moistening of the MJO during DYNAMO in ECMWF Reforecasts

AbstractReforecasts produced by the ECMWF Integrated Forecast System (IFS) were used to study heating and moistening processes associated with three MJO events over the equatorial Indian Ocean during the Dynamics of the Madden–Julian Oscillation (DYNAMO) field campaign. Variables produced by and derived from the IFS reforecast (IFS-RF) agree reasonably well with observations over the DYNAMO sounding arrays, and they vary smoothly from the western to eastern equatorial Indian Ocean. This lends confidence toward using IFS-RF as a surrogate of observations over the equatorial Indian Ocean outside the DYNAMO arrays. The apparent heat source Q1 and apparent moisture sink Q2 produced by IFS are primarily generated by parameterized cumulus convection, followed by microphysics and radiation. The vertical growth of positive Q1 and Q2 associated with the progression of MJO convection can be gradual, stepwise, or rapid depending on the event and its location over the broader equatorial Indian Ocean. The time for con.
Influence of complex terrain and anthropogenic emissions on atmospheric CO2 patterns–a high‐resolution numerical analysis

The accuracy of regional or mesoscale carbon budgeting by means of inverse modelling depends strongly on the ability of the atmospheric model to capture relevant atmospheric transport processes. In order to analyze the influence of terrain‐induced flow dynamics and intense local anthropogenic emissions, we present high‐resolution (forward) simulations of spatio‐temporal CO2 variations using a recent biosphere–atmosphere model. The selected region is characterized by complex terrain and both rural and densely populated areas. The results indicate that, in situations with weak synoptic forcing, the nocturnal near‐surface CO2 distribution is strongly affected by terrain‐induced turbulent kinetic energy (TKE) above mountain ridges and by local convergent downslope winds. By increasing the grid spacing from ≈ 1 to ≈ 3 km, we show that, due to the smoothed model topography, the atmospheric flow causing the CO2 heterogeneity cannot be resolved any more. Finally, we quantify the influence of intense anthropogenic CO2 sources on atmospheric CO2 concentrations. A significant anthropogenic signal can be identified around and downstream of industrial and urban areas, especially in the morning but also within a well‐mixed planetary boundary layer in the daytime. The results provide valuable information for including non‐background CO2 observations in mesoscale inverse modelling studies using coarser resolutions than in this study.
Proposition of New Testing Procedure for the Mechanical Properties of Bulk-Fill Materials

This study analysed flexural properties, microhardness, and the degree of conversion (DC) of five bulk-fill composites under clinically relevant conditions (4 mm thick specimens) in comparison to 2 mm specimens according to ISO 4049. Additionally, the effect of rapid polymerisation on 4 mm specimens was evaluated after accelerated aging. DC was measured using Fourier transform infrared spectrometry at 2 and 4 mm thick layers, while flexural properties and Vickers microhardness were tested using 16 × 2 × 2 mm or 16 × 2 × 4 mm specimens. Three polymerisation protocols were used: (I) “ISO”: 2 mm thickness, 1000 mW/cm2, double-sided; (II) “10 s”: 4 mm thickness, 1000 mW/cm2, one-sided; and (III) “3 s”: 4 mm thickness, 2600 mW/cm2, one-sided. Mechanical properties were tested after 1 day, after 10,000 thermocycles, and after 10,000 thermocycles followed by a 7-day immersion in absolute ethanol. The “ISO” protocol produced a higher DC and microhardness of all materials. Elastic modulus was significantly higher for the “ISO” protocol compared to the 4 mm specimens. The differences in flexural strength for all polymerisation protocols were equalised after thermocycling and immersion in absolute ethanol. All tested materials met the ISO 4049 flexural strength requirement (80 MPa) for all polymerisation methods and all aging conditions. Rapid polymerisation achieved nearly optimal properties (ISO), except for elastic modulus, which was significantly reduced in 4 mm samples.
Operation and Performance of Sufi-Led Political Parties in Contemporary Bangladesh

Although Sufi-led political parties have been active in Bangladesh for almost four decades, they have received little scholarly attention. Therefore, this article discusses the historical context within which post-independence Sufi/Pir-centred political parties emerged, their interaction with other parties, and their electoral performance. It also touches upon some basic issues relating to Pir-cum political leaders: once a Pir becomes a politician, does his previous relationship with his murids (disciple) remain intact? This paper concludes that instead of posing any meaningful challenge to the political regimes, Pir-led parties have developed a tendency to maximise their political opportunities by reaching various kinds of agreements with dominant political parties.
