Specifics of some anti-corruption measures in Russia within the framework of public and state security
Authors: Plotnikova Tatyana , Paramonov Andrey
Published: February 2021

In the current difficult conditions for the economy of our state, corruption crimes represent a higher level of danger. It is necessary to reform anti-corruption activities in order to increase its effectiveness. One of the radical measures in the field of anti-corruption will be the abolition of the presumption of innocence for corrupt illegal acts. The presumption of inno-cence is a fundamental and irremovable principle of criminal law, which is enshrined in article 14 of the Code of Criminal Procedure of the Russian Federation. Violation of this principle is impossible for criminal proceedings, but modern circumstances require timely, prompt, and sometimes radical so-lutions. It is worth not to neglect the measures of “insuring” on the part of law enforcement agencies, since otherwise it will increase the share of cor-ruption crimes in law enforcement agencies. The content of paragraph 4 of article 14 of the Criminal Procedure Code of the Russian Federation is man-datory even if the presumption of innocence for corruption crimes is can-celed: “A conviction cannot be based on assumptions”. At the same time, the principle of differentiation of punishment will be implemented by assigning the term of imprisonment from the minimum to the maximum, depending on the severity of the illegal act.

Published: February 2021

This study aimed to identifying the role of learning in developing multiple developmental intelligences for Kindergarten children from their mothers' point of view. The study sample consisted of (160) mothers who were distributed into two groups: the first group consisted of (80) mothers of children attending kindergartens with learning corners, and the second group consisted of (80) mothers of children attending traditional kindergartens. To achieve the study objectives, the descriptive method was used and a questionnaire for assessing learning corners and multiple developmental intelligences scale (MIDAS) were used. The study results showed that multiple developmental intelligences among the children attending kindergartens with learning corners were high, while multiple developmental intelligences among the children attending traditional kindergartens were medium. The results also showed that there are statistically significant differences in the total score and in the sub-scores for each of the multiple developmental intelligences between the children attending kindergartens with learning corners and those attending traditional kindergartens in favor of the children attending kindergartens with learning corners. The study recommended that concerned authorities should include learning corners in the classroom as they develop multiple intelligences.

Authors: Jovita Liliana Dea , Dewi Elisabeth
Published: February 2021

Krisis pengungsi merupakan permasalahan serius yang terus diperdebatkan dalam politik Eropa. Meningkatnya jumlah pengungsi yang masuk ke Eropa sejak tahun 2015 tersebut dikhawatirkan dapat menimbulkan ancaman terhadap aspek-aspek kehidupan masyarakat. Salah satu negara yang menerima jumlah pengungsi terbanyak adalah Jerman. Namun, di awal terjadi krisis pengungsi, Pemerintah Jerman tidak menganggap pengungsi sebagai ancaman, melainkan sebagai korban dari penindasan yang dialami di negara asalnya. Penolakan terhadap masuknya pengungsi ke Jerman justru datang dari partai sayap kanan di Jerman, yaitu Partai Alternative für Deutschland (AfD). Berbeda dengan Pemerintah Jerman, Partai AfD berpendapat bahwa pengungsi merupakan ancaman terhadap masyarakat Jerman. Artikel ini bertujuan untuk melihat bagaimana Partai AfD membentuk persepsi pengungsi sebagai ancaman, sekaligus upaya sekuritisasi yang dilakukan oleh partai. Penelitian dilakukan dengan menggunakan pendekatan konstruktivisme sosial, serta konsep keamanan non-tradisional dan konsep sekuritisasi. Metode pengumpulan data yang digunakan adalah studi Pustaka dan metode analisis yang digunakan adalah metode studi kasus, dengan kasus yang diteliti adalah krisis pengungsi di Jerman. Adapun hasil dari penelitian ini adalah Partai AfD membentuk persepsi bahwa pengungsi merupakan ancaman terhadap identitas kolektif masyarakat Jerman, demografi penduduk, perekonomian Jerman, serta keamanan internal maupun nasional. Hasil penelitian juga menunjukkan bahwa Partai AfD memanfaatkan persepsi pengungsi sebagai ancaman tersebut untuk meraih dukungan suara dalam Pemilu Federal Jerman tahun 2017.

INDO12, a 1/12 regional configuration of the NEMO3.1 physical ocean model covering the whole Indonesian EEZ has been developed and was running with 3D daily and 2D surface hourly outputs in the framework of the INDESO project. Validate the model results highly required for any downstream applications (services or scientific studies). In order to enhance confidence in using the INDO12 model outputs in Makassar Strait, qualitative comparisons with observed variables is performed. The datasets were used in this study provided by the INSTANT and MITF programs. Validation of model outputs was performed by compare the value of variables from simulation with observation results.The method of comparisons was conducted as follows:current velocities, temperature and salinity, volume transport. The volume transports differences especially occurred below the thermocline layer. The model was colder and fresher in the thermocline layer, whereas deeper the model was warmer and saltier.The differences of the volume transport and temperature distribution affected the transport-weighted temperature and 16°C isotherm depth. The model produced warmer transport-weighted temperature and deeper 16°C isotherm depth compared to the observations. It is concluded from the validation results that the model give a fairly good comparison with the in-situ data, especially for seasonally signals.Keywords: Validation, INDO12, Ocean Model, Makassar Strait, INSTANT and MITF Programe

Published: February 2021

Estuaries are influenced by the mixture of river water with seawater; creating unique ecosystems with several physical and chemical processes affecting the water quality. Spatial and temporal assessment of the composition, abundance, and distribution of zooplankton fauna of Uta Ewa Estuarine water system was carried out between May 2019 and February 2020 to assess the effects of anthropogenic activities on the zooplankton assemblage. Water and Zooplankton samples were collected from three (3) stations using standard procedures. Some parameters like water temperature, dissolved oxygen, hydrogen-ion, electrical conductivity, and turbidity were determined in-situ. The ranges of the physico-chemical parameters were: water temperature (24.9-25.3oC), EC (62.3-70.9mS/m), pH (6.5-6.7), turbidity (12.0-28.0NTU), DO (3.8-4.7mg/L), BOD (2.3-3.2mg/L), phosphate (3.2-5.2mg/L), and nitrate (3.0-6.3mg/L). ANOVA showed a significant difference (p<0.05) in the spatial and temporal means values of some parameters. A total of 1,067 individuals from 30 zooplankton taxa and 4 taxonomic groups were recorded. Rotifers (33.4%) were the dominant group, followed by protozoa (32.9%), copepods (20.9%) and cladocerans (13.8%). Station 1 had the highest abundance (388 individuals), station 2 (303 individuals) and station 3(375 individuals). The higher number of individuals (193) was recorded in August 2019. The biodiversity indices pointed to slightly polluted to stable environment. This study showed that the water quality and zooplankton community was influenced by anthropogenic activities both spatially and temporally but season also played a major role in the temporal variation. In conclusion, the water quality was deteriorating due to anthropogenic activities, which in turn affected the structure of zooplankton community. Keywords: Abundance, Assessment, Zooplankton, Physicochemical, Estuary

Mackerel scad (Decapterus macarellus) is one of the important economical caught in the Indian Ocean West Sumatra waters captured using purse seine. Increased production of mackerel scad will lead to increased exploitation, causing population changes. Therefore, research was carried out to find out the biological aspects of the fish so that resource management can be done. The sampling was conducted in Lampulo, Sibolga, and Air Bangis from February to November 2016 with total samples of 716 fishes. This research was conduct to study some biological aspects which consist of size distribution, length-weight relationship, sex ratio, gonad maturity level, the length at first capture, and length of the first maturity in Indian ocean west Sumatera waters. The results showed that the size of the mackerel scad had ranged between 16 - 33.6 cm FL and the average was 24.5 cm. Growth patterns are allometric negative, sex ratio male and female in an unbalanced condition. The mackerel scad is most caught by purse seine in maturity condition. The average length at first captured was 25.08 cm FL and length at first mature was 20.47 cm FL. These were an ideal biological condition and must be maintained because it provides an opportunity for fish to increase the population. The mesh size purse must follow the Ministry of Maritime Affairs and Fisheries Regulation Number 71/2016 that adjusted for minimum at 1 inch. Keywords: Mackerel scad, Indian Ocean, purse seine

Correction of the Koenig Formula for the Kinetic Energy of a Rotating Solid
Authors: Alyushin Yuriy
Published: February 2021

An exact solution is obtained for the kinetic energy in the general case of the spatial motion of solids with arbitrary rotation, which differs from the Koenig formula by three additional terms that take into account the change in the centrifugal moments of inertia when the body rotates. The description of motion in the Lagrange form and the superposition principle are used, which provides a geometric summation of the velocities and accelerations of the joint motions in the Lagrange form for any particle at any time. The integrand function in the equation for kinetic energy is represented as the sum of the identical velocity components of the joint plane-parallel motions. In the general case of motion with 6 degrees of freedom, the energy of rotational motion is determined by three axial moments of inertia, as in the Koenig formula, and three additional centrifugal moments, which take into account the rotation of the body. They can be calculated through 6 integral characteristics of the density distribution, determined for the initial position of the body.
A Transition of Shared Mobility in Metro Cities- a Challenge post Covid-19 Lockdown
Authors: Aman Mohd , Miftah Bushra
Published: February 2021

This chapter is written for the welfare of the society, questioning and enlightening the effects of the increment or decrement in the percentage of quality of air causing pollution due to the rise in the traffic post-lockdown due to COVID-19 in metro cities, specifically in Delhi. In this chapter, we address the question about people's preference in moving in the shared taxis to their workplaces or their reluctance and denial of the idea of moving in the shared vehicle because of the fear of getting infected. The sensitivity of the situation will compel the people to move in a single occupied vehicle (SOV). The rise in the number of vehicles on the roads will result in traffic jams and different kinds of pollution where people battling with the pandemic will inevitably get exposed to other health-related issues. We use a BPR (Bureau of Public Roads) model to combat this issue endangering the environment and public health. We exploit the BPR function to relate average travel time to the estimated number of commuters travelling by car. We collect mode share data from the NITI Ayog, the State Resource Centre and other authentic sources, which gives unique figures of the impact of shared mobility in India and how, in its absence, various sectors will get affected. Using the given data and the BPR, we evaluate increased vehicle volumes on the road if different portions of transit and carpool users switch to single-occupancy vehicles and its effect on multiple other factors. Based on the study of densely populated city, Delhi, we predict that cities with significant transit ridership are at risk for extreme traffic and pollution unless transit systems can resume safe with effective protocols.

The high price of bioethanol is the barrier of its implementation as renewable energy sources. Therefore, efforts to reduce its price is an important factor to drive the implementation. Stripping is a way to separate bioethanol from the broth which will be cheaper than distillation process. This research was aimed to separate bioethanol from its fermented molasses. The effect of feed flow rate, air flow rate and feed temperature were investigated. A column with inside diameter of 0.1 m was used and packed with 0.02 x 0.016 m PVC rashig ring at 1 m of bed. The broth was fed from the top side and the air stripper was flown down from the bottom side. Six millimeters of the top product was collected at steady state condition for analysis of bioethanol concentration. The best experiment was the one which had feed flow rate 1,5 L/min and stripping air flow rate of 5,85 L/min. It resulted bioethanol content of 19.39% or equivalent to 38.5% stripped out of the broth.

Abstract. A sponge was made with a basic ingredient of glucomannan with the addition of charcoal. In this experiment, the effect of two types of alkaline solution i.e., Na2CO3 and NaOH, either the size and the amount of charcoal, were studied on the sponge's characteristics. The sponge was made by dissolving glucomannan flour in water. This step was followed by mixing the solution with Sodium Laureth Sulfate (SLS) and charcoal. The alkaline solution was added to form a wet gel. The dry sponge was obtained after thawing and sun drying. The sponge's characterization was done by observing the foam cavity using a camera microscope and analyzing water absorption, sponge expansion, and iodine adsorption. The sponge has cavities with a size between 0.1 mm to 0.25 mm. Sponges with water absorption and high expansion were obtained by adding NaOH solution, one gram of charcoal and the size of charcoal -50+60 mesh. Sponge produced using Na2CO3 with 0.5 gram charcoal with size - 60+70 mesh has a high diameter cavity and a high adsorbed iodine value.

Estimating Bridge Reliability by Using Bayesian Networks
Authors: Groeneveld Andrew B. , Wood Stephanie G. , Ruiz Edgardo
Published: February 2021

As part of an inspection, bridge inspectors assign condition ratings to the main components of a bridge’s structural system and identify any defects that they observe. Condition ratings are necessarily somewhat subjective, as they are influenced by the experience of the inspectors. In the current work, procedures were developed for making inferences on the reliability of reinforced concrete girders with defects at both the cross section and the girder level. The Bayesian network (BN) tools constructed in this work use simple structural m echanics to model the capacity of girders. By using expert elicitation, defects observed during inspection are correlated with underlying deterioration mechanisms. By linking these deterioration mechanisms with reductions in mechanical properties, inferences on the reliability of a bridge can be made based on visual observation of defects. With more development, this BN tool can be used to compare conditions of bridges relative to one another and aid in the prioritization of repairs. However, an extensive survey of bridges affected by deterioration mechanisms is needed to confidently establish valid relationships between deterioration severity and mechanical properties.
BITE MARKS ON AN AETOSAUR (ARCHOSAURIA, SUCHIA) OSTEODERM: ASSESSING LATE TRIASSIC PREDATOR-PREY ECOLOGY THROUGH ICHNOLOGY AND TOOTH MORPHOLOGY
Authors: DRYMALA SUSAN M. , BADER KENNETH , PARKER WILLIAM G.
Published: February 2021

Trace fossils such as bite marks provide rare, direct evidence of animal behavior, including predator-prey interactions. We present an osteoderm of the aetosaur Typothorax coccinarum from the Late Triassic Chinle Formation of Arizona with several punctures and scores, interpreted here as bite marks, preserved as evidence of predation/scavenging by a large carnivore. The marks include a single bite producing four subparallel fusiform pits on the ventral surface and several additional marks, including striated scores, on the dorsal surface. These traces are described and compared with known contemporaneous carnivorous taxa to determine the source of the bite marks. Some Triassic carnivores, including theropod dinosaurs can be ruled out because of tooth shape and serration densities. Phytosaurs and large paracrocodylomorphs remain as likely candidates based on tooth morphology. Although some phytosaur teeth are too rounded to produce the marks seen in this specimen, we demonstrate that the more lingually flattened teeth typically found in the posterior section of the snout are sufficiently mediolaterally compressed to produce a fusiform pit. A protective function for aetosaur osteoderms cannot be confirmed presently, but the extensive carapace these bones formed would have been a major barrier to both scavengers and active predators and may preserve more feeding/predation traces than previously thought. The bite marks described herein support the hypothesis that aetosaurs were prey items of large archosauromorphs, expanding our understanding of the complex, and seemingly carnivore dominated Late Triassic terrestrial ecosystems of North America.
Morphostructural Setting and Tectonic Evolution of the Central Part of the Sicilian Channel (Central Mediterranean)

Published: February 2021

The Plio-Quaternary tectonic evolution of the central sector of the Sicilian Channel and the resulting morphostructural setting have been analyzed using a large geophysical dataset consisting of multichannel seismic profiles, which some of them never published, and available bathymetric data. This area hosts two regional-scale tectonic domains that registered the complex pattern of deformation occurred since the Early Pliocene: (1) the Sicilian Channel Rift Zone (SCRZ), which can be divided into a western sector formed by the Pantelleria graben (PG) and in a eastern one represented by the Linosa and Malta grabens (LG and MG) and (2) the Capo Granitola-Sciacca Fault Zone (CGSFZ), a NNE-oriented lithospheric transfer zone that crosses the Sicilian Channel from the Sicily coast to the Linosa Island, of which only its northern part has been studied to date. Data interpretation has allowed achieving the following outcomes: (i) the presence of an alternation of basins and structural highs forming a NNE-oriented separation belt between the western and eastern sectors of the SCRZ, and interpreted as the shallow expression of the southern part of the CGSFZ; (ii) a NE-oriented tectonic lineament separating the MG in a northern and southern part, and interpreted as the southern prosecution of the Scicli-Ragusa Fault System; (iii) the presence of syn-rift deposits in the Plio-Quaternary fill of the grabens, suggesting that the opening of the grabens of the SCRZ was coeval, and started since Early Pliocene in the framework of a NW-oriented right-lateral transtensional mega-shear zone; (iv) continental rifting ended around the Early Calabrian, during which extensional tectonics dominated along the separation belt; (v) the CGSFZ conditioned the SCRZ configuration at a regional scale, leading to the development of the PG in the western sector and of the LG and MG in the eastern one; and (vi) after the Early Calabrian, the PG and the southern MG followed a different tectonic evolution with respect to the LG and northern MG. The syn-rift deposits of the PG and southern MG were sealed by an undeformed post-rift succession, while the LG and the northern MG suffered a basin inversion that ended around the Latest Calabrian time. During this stage, the separation belt was affected by a transpressional tectonics. At present, the grabens of the Sicilian Channel seem to be tectonically inactive, while the CGSFZ represents an active tectonic domain.

Published: February 2021

A análise multidimensional da deficiência contribui para o entendimento de práticas espaciais relacionadas à procura e obtenção de saúde. No presente artigo, pretendemos discutir a necessidade e importância do uso de procedimentos da Pesquisa Qualitativa para analisar a deficiência motora a partir das representações dos sujeitos que a vivencia, tanto de forma individual quanto coletiva, no espaço Presidente Prudente (SP). Para tanto guiamos nosso estudo, principalmente, por procedimentos da Pesquisa Qualitativa com fontes orais, no intuito de obter relatos de pessoas com deficiência motora que vivem na cidade pesquisada. A partir da pesquisa, foi possível descobrir que existem várias dimensões a serem consideradas para entender o contexto destas pessoas. E isso pode ser observado pelos dados resultantes das entrevistas realizadas e em respostas sobre quando, como e quais os motivos se tornaram deficientes motores. O que nos possibilitou considerar que, implantar um rótulo generalizado de pessoa com deficiência motora pode dificultar o conhecimento da realidade desses sujeitos, uma vez que o inclui numa categoria estanque, ignorando outras categorias, assim como qual representação social (social e coletiva) estes indivíduos fazem da deficiência. Nesta perspectiva, este artigo propõe possibilidades temáticas, importantes, que podem ser estudas pela Geografia a partir de pesquisas histórico-dialéticas com enfoque qualitativo.

Coronary heart disease (CHD) is the result of complex metabolic disorder caused by various environmental and genetic factors, and often comorbidity with anxiety. Anxiety was known to an independent risk factor for the adverse cardiovascular events and mortality in patients with CHD, while how stress-induced anxiety behavior impacts the metabolome of blood plasma in CHD patients and contributes to CHD worse is unclear. So this study aimed to investigate the effect of anxiety on metabolome of plasma in CHD patients. According to the inclusion and exclusion standard the blood plasma of CHD patients and CHD comorbidity with anxiety were collected after ethics approval. Metabolome analysis of blood plasma using liquid chromatography mass spectrometry (LC/MS) was performed, then multivariate data analysis was applied to evaluate the data. Disturbance of 39 plasma metabolites were altered in CHD patients accompany by anxiety patients as compared to control group. These disturbed metabolites were mainly involved in tryptophan metabolism, pyrimidine metabolism, glycerophospholipid metabolism, pentose phosphate metabolism, phenylalanine metabolism, pentose and glucuronate interconversions. The most significant pathway was tryptophan metabolism including the down-regulation of tryptophan and serotonin. In addition to tryptophan metabolism, the glycerophospholipids metabolism, pentose and glucuronate interconversions and pentose phosphate pathway were also greatly affected in this study. These results suggest that anxiety may further disturb CHD three translation of material metabolome. Besides theses metabolism pathway pyrimidine metabolism disturbed significantly which can aggravate the disease in patients with CHD. From these resoults the plasma metabolites monitoring was suggested to be recommended and may be conducive to early detect biomarkers to personalized treatment anxiety in patients with CHD in future.

Background

Esophagojejunal anastomotic leakage is a serious complication after total gastrectomy. This study evaluated the safety and efficacy of transnasal placement of drainage tube, jejunal decompression tube, and jejunal nutrition tube under fluoroscopy for treatment of esophagojejunal anastomotic fistula after gastrectomy in gastric cancer patients.
Methods

Retrospective review of patients with esophagojejunal anastomotic fistula treated with transnasal placement of abscess drainage tube, decompression tube, and jejunal nutrition tube under fluoroscopy. Fistula healing time, patient survival, and Eastern Cooperative Oncology Group (ECOG) performance status before and after treatment were evaluated.
Results

Thirty-eight patients were included in the study. Insertion of the transnasal abscess drainage tube, jejunal decompression tube, and nutrition tube was successful on the first attempt in all patients. Simple transnasal drainage was used in 27 patients (one drainage tube placed plus one drainage tube replacement in 15 patients, and one drainage tube placed in 12 patients), and transnasal drainage plus percutaneous abscess drainage in 11 patients. After placement of the tube, the mean volume of drainage was 120 ml (10–850 mL); the amount steadily decreased from then on. The fistula healed in 33 patients. Median time to fistula healing was 78 days (6-248 days). Two patients suffered gastrointestinal bleeding after the procedure but one patient died.
Conclusions

Transnasal insertion of transnasal abscess drainage tube, jejunal decompression tube, and jejunal nutrition tube under fluoroscopy appears to be a simple, minimally invasive, effective, and safe method for treating esophagojejunal anastomotic fistula after gastrectomy for gastric cancer.

Abnormal DNA methylation (DNAm) has been associated with the onset and development of cancer; thus, it is vital to develop an in-depth understanding of DNAm patterns as well as the accompanying variations across multiple cancer cohorts to explore the mechanism of cancer development. The use of DNAm biomarkers holds great promise for the standardization of cancer diagnostics in clinical trials. This research focused on the discovery of universally specific or common biomarkers that would be. First, we explored primary cancers with significantly higher variations compared with normal solid tissues, as well as the heterogeneity in methylation in different cancers. Second, we found 138 differently methylated CpGs (DMCs) with a common methylation trend and eight common differently methylated regions (DMRs) in different cancer cohorts. Third, we found 99 DMCs to distinguish 32 different cancer cohorts in Random Forest (RF) analysis because of the specificity mechanism, but each DMC still had high instability. Additionally, the most important 10 DMCs among the 99 DMCs affected the survival time of cancer individuals. By employing a comprehensive analysis of DNAm patterns and variations in cancers, our results could facilitate the development of biomarkers that are universally specific and common features among DNAm profiles across multiple cancer cohorts. Our findings also provide new insights for the prevention and treatment of cancer.

Background: The application of Deep Learning (DL) in MR image reconstruction is increasingly gaining attention due to its potential of increasing image quality and reducing acquisition time. However, the technology hasn’t been yet implemented in clinical routine. The aim of this study was therefore to describe the implementation of this novel DL image reconstruction for turbo spin echo (TSE) sequences in clinical workflow including a thorough explanation of the required steps and an evaluation of the obtainable image quality compared to conventional TSE.Methods: DL image reconstruction using a variational network was clinically implemented to enable acquisition of accelerated TSE sequences. After internal review board’s approval and informed consent, 30 examinations for knee, shoulder, and lumbar spine in 15 volunteers at 3 T were included in this prospective study. Conventional TSE sequences (TSE) and TSE with deep learning reconstruction (TSEDL) were compared regarding overall image quality, noise, sharpness, and subjective signal-to-noise-ratio (SNR), as well diagnostic confidence and image impression. Comparative analyses were conducted to assess the differences between the sequences. A survey on technologists’ acceptance was performed for DL image reconstruction. Results: DL image reconstruction was successfully implemented in a clinical workflow and TSEDL allowed a remarkable time saving of more than 50%. Overall image quality, diagnostic confidence and image impression for TSEDL were rated as excellent (median 4, IQR 4-4) and comparable to TSE (image quality: p=0.059, diagnostic confidence: p=0.157, image impression: p=0.102). Noise, sharpness, artifacts, and subjective SNR for TSEDL reached significantly superior levels to TSE (noise: p<0.001, sharpness: p=0.001, artifacts: p=0.014, subjective SNR: p<0.001). Technologists reported high levels of acceptance for DL image reconstruction. Required time for the reconstruction process was rated moderate and longer than standard sequences (median 2, IQR 2-3). Required time and effort for the implementation in daily workflow was rated as low effort (median 4, IQR 3-4). General applicability of DL reconstruction as well as acceptance of DL sequences in clinical routine were rated excellent (median 4, IQR 3-4). Conclusion: DL image reconstruction for TSE sequences can be implemented in clinical workflow and enables a remarkable time saving (>50%) in image acquisition while maintaining excellent image quality.Trial registration: Your clinical trial is officially registered at the German DRKS with the registration number: DRKS00023278.

By combining the discrete element method (DEM) with computational fluid dynamics (CFD), a three-dimensional CFD–DEM fluid–solid coupling microscopic computational model was established to analyse the micro-mechanism of instability and failure in a coal-bearing soil slope during rainfall. According to the results, the main failure mode of coal-bearing soil slopes simulated by the CFD–DEM fluid–solid coupling model was rainwater washing, and the slope sliding surface was predicted as an approximately linear segment. The adaptability of this numerical method was verified by considering its similarity to a range of rain-washed slopes in an outdoor model test. During rainfall, microscopic parameters, such as force chain and coordination number slope soil particles, changed, as confirmed by changes in the coordination number of the slope’s top particles from 6.0 in the initial state to 3.2 in the unstable state. This was directly related to the macroscopic mechanics of the slope soil. In this study, based on the analysis of the changes in the microscopic parameters of the particles, the law of failure evolution of coal-bearing soil slopes during rainfall was explored from the microscopic perspective. This study not only provides a theoretical basis for the protection design and construction of coal-bearing soil slopes in the region but also encourages an effective analytical method for the macroscopic mechanical law of discrete media from a micro-macro perspective in geotechnical engineering.

AimTo assess the predictive and prognostic aim of interim and end-treatment 18F-fluorocholine PET/CT (FCH-PET/CT) and 99mTc-methilen diphosphonate bone scintigraphy (BS) in patients with castration-resistant prostate cancer and bone metastases (CRPC-BM) treated with Radium 223 dichloride (223Ra). Methods: Prospective and multicentre ChoPET-Rad study including 82 patients with CRPC-BM. Baseline, after 3 (interim) and 6 doses (end-treatment) BS and FCH PET/CT were performed in patients who meet the study criteria. Clinical variables, imaging and clinical progression were obtained and their association with progression free survival (PFS), and overall survival (OS) was studied. Agreement between BS and FCH PET/CT response was assessed using Kappa (K) analysis.Results:Median of PFS and OS was 3 and 16 months, respectively. Agreement between interim BS and FCH PET/CT was weak (K: 0.28; p=0.004). No agreement was observed between end-treatment diagnostic studiesInterim and end-treatment FCH PET/CT were related to PFS (p=0.011 and p<0.001, respectively). Therapeutic failure and interim BS and FCH PET/CT showed association with OS (p<0.001, p=0.037 and p=0.008, respectively).Conclusions: Interim and end-treatment FCH PET/CT were good predictors of biochemical progression in patients treated with 223Ra. Therapeutic failure and progression in interim BS or FCH PET/CT were adverse factors for OS.
