Repeated degradation and progradation of a submarine slope over geological timescales
Authors: Jackson Christopher A-L. , McAndrew Andrew E. , Hodgson David M. , Dreyer Tom 
Published: March 2021

ABSTRACTSubmarine slopes prograde via accretion of sediment to clinoform foresets and degrade in response to channel or canyon incision or to mass-wasting processes. The timescales over which progradation and degradation occur, and the large-scale stratigraphic record of these processes, remain unclear due to poor age constraints in subsurface-based studies and areally limited exposures of exhumed systems. We here integrate 3D seismic reflection and borehole data to study the geometry and origin of ancient slope canyons developed in late Mesozoic strata of the Måløy Slope, offshore Norway. Slope degradation and canyon incision commenced during the late Kimmeridgian, coincident with the latter stages of rifting. Later periods of canyon formation occurred during the Aptian to Albian and the Albian to Cenomanian, during early post-rift subsidence. The canyons are straight, up to 700 m deep, and 10 km wide on the upper slope and die out downdip onto the lower slope. The canyons trend broadly perpendicular to and crosscut most of the rift-related normal faults, although syn-filling fault growth locally helped to preserve thicker canyon-fill successions. The headwalls of the oldest (late Kimmeridgian) canyons are located at a fault-controlled shelf edge, where younger canyons overstep this fault, which was inactive when they formed, extending across the paleo-shelf. Downslope, Aptian to Albian canyons either erode into the older, late Kimmeridgian to Barremian canyon fills, forming a complicated set of unconformities, or in the case of the Albian to Cenomanian canyons, die out into correlative conformities. Boreholes indicate that the canyon bases are defined by sharp, erosional surfaces, across which we observe an abrupt upward shift from shallow- to deep-marine facies (i.e., late Kimmeridgian canyons), or deep marine to deep marine facies (Aptian to Albian and Albian to Cenomanian canyons). Missing biostratigraphic zones indicate the canyons record relatively protracted periods (c. 2–17 Myr) of structurally enhanced slope degradation and sediment bypass, separated by &gt; 10 Myr periods of deposition and slope accretion. The trigger for slope degradation is unclear, but it likely reflects basinward tilting of this tectonically active margin, enhanced by incision of the slope by erosive sediment gravity flows. The results of our study have implications for the timescales over which large-scale slope progradation and degradation may occur on other tectonically active slopes, and the complex geophysical and geological record of these processes. We also show that canyon formation can cause large volumes of margin-derived sediment to bypass proximal sub-basins within rifted terranes, an important process not currently captured by marine rift-basin tectono-stratigraphic models.

Published: March 2021

La identificación humana es uno de los objetivos principales de la odontología forense. Para llegar a esta identificación científica, el odontólogo debe encontrar propiedades tales como edad, sexo y características odontológicas individualizantes. La cavidad oral ofrece muchas posibilidades para la identificación, no solo a partir de los dientes y huesos de la cavidad craneal, sino también de los tejidos blandos orales; en consecuencia, ofrece un mayor campo de estudio. La rugoscopía, técnica basada en el estudio de las rugas palatinas, es un método de identificación muy poco explorado y de gran ayuda en la odontología forense para identificar personas. Las rugas palatinas son estructuras inmutables y perennes que, por su ubicación en la cavidad oral, están protegidas de cualquier trauma y no se alteran con la vecindad de las prótesis dentales ni por sustancias químicas. Ya que todos presentamos rugas diferentes en cuanto a su tamaño, posición, número y disposición (su forma no cambia desde el nacimiento hasta la muerte), las rugas constituyen elementos importantes en el proceso de identificación de personas en casos en los que las huellas dactilares son irrecuperables. Por tanto, el objetivo de esta investigación es revisar la reelevancia del análisis rugoscópico como un método efectivo y de bajo costo para la identificación de sujetos vivos, cadáveres recientes y cadáveres momificados o antiguos.
Escisión de torus mandibular bilateral en paciente sistémicamente comprometido: reporte de caso
Authors: Jiménez-Castellanos Fabio Andrés , Arango-Piñeros Dayana Andrea , Toloza-Cubillos Camila Andrea 
Published: March 2021

Introducción: El torus mandibular es un crecimiento exofítico óseo ubicado en el área lingual de la mandíbula, generalmente bilateral. Puede estar asociado con trastornos temporomandibulares, afectar la pronunciación, producir halitosis, interferir con la deglución y causar dolor en la mucosa cuando está bajo prótesis mal diseñadas. Normalmente, el tratamiento no es necesario, excepto por necesidades protésicas, problemas funcionales, retención de alimentos, trastornos fonéticos o en caso de que se vaya a usar como injerto óseo autólogo. El objetivo de este reporte de caso fue realizar la escisión del torus mandibular bilateral en un paciente sistémicamente comprometido para su posterior rehabilitación con una prótesis parcial removible. Se realizo la atención de una paciente de 66 años sexo femenino, a quien, luego de analizar los medios diagnósticos y la evidencia científica, se le pudo realizar la escisión del torus mandibular bilateral de forma atraumática; esto permitió el correcto asentamiento de una prótesis parcial removible. La escisión del torus mandibular bilateral es un procedimiento seguro y predecible, y ayuda a evitar complicaciones protésicas, como el diseño de la estructura, y biológicas, como úlceras, depósitos de comida o halitosis, lo que devuelve laestabilidad y la función al sistema estomatognático.

Summary
Annulus pressure buildup (APB) problems in shale gas wells seriously affected on the safety and efficient exploitation of shale gas all around the world. The sealing failure of the cement sheath on interfaces caused by periodically changed fluid pressure in casing during hydraulic fracturing is treated as the main reason for APB in shale gas wells. Many methods are put forward to solve the APB problem in the field, and fortunately, the preapplied annulus backpressure (PABP) method shows an excellent utility. In this paper, an analytical model is established to explain the mechanism of the PABP method increasing the sealing ability of the cement sheath. The residual strain of the cement sheath and radial stress on interfaces are considered to analyze the factors that affect the effectiveness of the PABP method. In addition, based on the field data, an experimental device is established to test the validity of the PABP method and to certify the accuracy of the analytical model established in this paper. The analytical results show that the thickness of the casing has little effect on radial stress on interfaces. The outer diameter of the casing and the thickness of the cement sheath can temperately affect the radial stress. The elastic modulus of the cement sheath and the formation rock can significantly affect the radial stress. The higher elastic modulus of the cement sheath can dramatically increase the radial stress on interfaces. On the contrary, the higher elastic modulus of formation rock will induce smaller radial stress on the interfaces. In the field, the number of newly added shale gas wells with APB problems has dramatically decreased by using the PABP method. The work in this paper can be significantly useful for researchers and engineers to reduce the APB in shale gas wells.

Published: March 2021

Abstract
Background: The ability to reproduce efficiently is an important characteristic that has evolved through natural selection. Nutrition can modulate reproductive activities at different levels, its effect on nutrition is therefore complex and less predictable. This study aims at investigating the underlying effect of persistent dietary protein deficiency during early life on reproductive parameters of subsequent (F1 and F2) generations.Method: Rats in group of four (4) were fed daily, with different ration of protein diet (PD) formulated as: 21% protein diet, 10%protein diet, 5%protein diet and control diet (rat chow, containing 16-18% protein). They were fed ad libitum before mating, throughout gestation and lactation, and next generations were weaned to the maternal diet. Reproductive function analysis (which include; gestation and pubertal hormonal profiling, onset of puberty, oestrus cyclicity, sexual response) and morphometric analysis of the ovarian structure were carried out to assess associated consequences.Results: showed significant reduction in the fertility index as a consequence of altered reproductive function in the protein deficient models at P≤ 0.05. Low protein diet posed suboptimal intrauterine condition, which was linked to increased prenatal morbidity and mortality, lowered birthweight delayed onset of puberty, induced cycle irregularity, altered follicular maturation and endocrine dysfunction in the protein deficient groups. Reproductive status of an individual female organism critically depends on the maintenance of ovarian structure and function that has been associated with the hypothalamic pituitary-gonadal axis, hormonal events and sexual maturity.Conclusion: There is therefore an association between persistent early life protein deficiency and reproductive response which mechanistically involves life-long changes in key ovarian cytoarchitecture and function.

Abstract
Nanoparticle passivation by molecular recognition moieties (small molecules, aptamers, antibodies) imputes unique characteristics to nanoparticles (NPs) and unlocks their fascinating selectivity to targeting disease sites. Although non-passivated nanomaterials may archive selective targeting by exploring NP features and their interaction with biofluids proteins, such studies are scarce in the literature. Here, we report spherical manganese-based carbonaceous NPs (MnCQD), which specifically target mice kidneys after intravenous injection, even without direct surface chemical modification. Also, the NPs provide high image contrast in T1 magnetic resonance imaging (MRI) with subtle toxicological effects. The
unexpected selectivity of MnCQD to the kidney has been examined based on their determined intrinsic properties and their interaction with two blood proteins: Bovine Serum Albumin (BSA), and Human Transferrin (HTF). More particularly, aspects such as size, composition, superficial charge, spectroscopic features, interaction mechanism, affinities, thermodynamic, and protein structural changes have been investigated. All these results highlight the excellent potential of MnCQD as a low toxic T1-MRI contrast agent and open the prospect of using non-functionalized NPs as a selective agent to target specific organs.

During 2020, at the level of legislative initiatives, there is an active discussion about the content of education and outreach activities. Due to the «vagueness» of the concepts of «education» and «educational activity» in academic circles, it is difficult to differentiate various kinds of activities that are valuable in broadcasting high-quality and meaningful information to a wide audience. The authors of the article consider the essential features of education in relation to the objectives of non-formal education and the principles set forth in the Model Law of 2002. The purpose of the article is to propose the author's definition of the concepts of «education» and «educational activity», considering the educational and educational potential in the conditions of mediatization of information and communication, leisure and educational environment. The empirical basis of the article is the materials of scientific publications, the content of the Model Law «On educational activities» and the Concept of educational activities presented in «Education for the future». Research results: 1.	The authors considered the connection between education and educational activities, carried out their substantive analysis, determined their mission and revealed their mechanisms and principles of organization. 2.	The qualitative component of educational activities is considered both at the level of providing the opportunity to carry out worldview, value-orientated, educational functions, and at the level of particular practices. 3.	The principles of educational activities are determined.
The removal efficiencies and mechanism of aniline degradation by peroxydisulfate activated with magnetic Fe-Mn oxides composite
Authors: Qiao Lin , Shi Yu , Cheng Qingli , Liu Bingtao , Liu Jing 
Published: March 2021

Abstract
The Fe-Mn oxides composite prepared by a chemical co-precipitation method was used as a heterogenous peroxydisulfate catalyst for the decomposition of aniline. This study investigated the mechanism of aniline degradation by PDS activated with catalyst. Reactive species resulting in the degradation of aniline was investigated via radical quenching experiments with different scavengers, including methanol, tert-butyl alcohol, EDTA and sodium azide. Based on the experiments made here, it is speculated that the predominant reactive species responsible for the degradation of aniline may be holes and singlet molecular oxygen rather than SO4·− and ·OH radicals. The degradation of compounds in catalyst/peroxydisulfate system was put forward. The three possible intermediates were speculated by high performance liquid chromatography-mass spectrometry, and two possible degradation pathways were proposed.
Development of ANN model for discharge prediction and optimal design of sharp-crested triangular plan form weir for maximum discharge using linked ANN–optimization model
Authors: Ayaz Md. , Mansoor Talib 
Published: March 2021

Abstract
Triangular plan form weirs are advantageous over a normal weir in two ways. Within the limited channel width, use of such a weir increases the crest length and hence for a given head, increases the discharge and for a given discharge, reduces the head in comparison with a normal weir. In a previous study, researchers proposed an empirical equation to compute the discharge coefficient of a triangular plan form weir. The prediction error on the discharge coefficient was ±7% from the line of agreement. In the present study, an ANN model has been utilized to train randomly selected 70% data, with 15% tested and validation made for the remaining 15% data. The model predicts the discharge coefficient with a prediction error in the range of ±2.5% from the line of agreement, thereby decreasing the prediction error in Cd by 64%. Also, the sensitivity analysis of the developed ANN model has been performed for all the parameters (weir height, skew weir length and flow depth) involved in the study and the weir height was found to be the most sensitive parameter. Furthermore, the linked ANN–optimization model has been developed to find the optimal values of design parameters of a triangular plan form weir for maximum discharge.

Abstract- The determinants of bank performance can be grouped into three groups, namely; 1) bank specific factors related to management decisions and policy objectives, 2) industry factors related to industrial structure and market growth, and 3) macroeconomic factors that reflect the economic conditions in which the bank operates. This study analyzes the effect of bank-specific factors and industry factors on banking performance using panel data regression analysis on a sample of 39 Indonesian Commercial Banks during the 2015-2019 period. Bank specific factors consist of bank size, efficiency, and capital adequacy, while the industrial factor in this study is the market structure which includes market concentration and market share. Banking performance is measured by Return on Equity and Net Interest Margin. The results of this study indicate that bank size and efficiency (BOPO) has a negative and significant effect on banking performance. Capital adequacy and market concentration have no effect on banking performance. Meanwhile, the market share variable has a positive and significant effect on banking performance as measured by Net Interest Margin but does not affect banking performance as measured by Return on Equity. Keywords : bank size, efficiency, capital adequacy, market structure, banking performance Abstrak- Determinan kinerja bank dapat dikelompokkan menjadi tiga kelompok yaitu ; 1) faktor spesifik bank yang terkait dengan keputusan manajemen dan tujuan kebijakan, 2) faktor industri yang terkait struktur industri dan pertumbuhan pasar, dan 3) faktor makroekonomi yang mencerminkan keadaan ekonomi dimana bank beroperasi.
