Aerothermal Characterization of a Rotating Ribbed Channel at Engine Representative Conditions—Part II: Detailed Liquid Crystal Thermography Measurements

The present two-part work deals with a detailed characterization of the flow field and heat transfer distribution in a model of a rotating ribbed channel performed in a novel setup which allows test conditions at high rotation numbers (Ro). The tested model is mounted on a rotating frame with all the required instrumentation, resulting in a high spatial resolution and accuracy. The channel has a cross section with an aspect ratio of 0.9 and a ribbed wall with eight ribs perpendicular to the main flow direction. The blockage of the ribs is 10% of the channel cross section, whereas the rib pitch-to-height ratio is 10. In this second part of the study, the heat transfer distribution over the wall region between the sixth and seventh ribs is obtained by means of liquid crystal thermography (LCT). Tests were first carried out at a Reynolds number of 15,000 and a maximum Ro of 1.00 to evaluate the evolution of the heat transfer with increasing rotation. On the trailing side (TS), the overall Nusselt number increases with rotation until a limit value of 50% higher than in the static case, which is achieved after a value of the rotation number of about 0.3. On the leading side (LS), the overall Nusselt number decreases with increasing rotation speed to reach a minimum which is approximately 50% of the one found in static conditions. The velocity measurements at Re = 15,000 and Ro = 0.77 provided in Part I of this paper are finally merged to provide a consistent explanation of the heat transfer distribution in this model. Moreover, heat transfer measurements were performed at Reynolds numbers of 30,000 and 55,000, showing approximately the same trend.

One pullus Cetratothoa capri parasite was found inside the bluefish gill, P. saltatrix from the coasts of Libya, in the southern Mediterranean determination, the infection rate of the fish was 2.5%. This is the first study from Libya on the presence of C. capri in bluefish.
Characteristic of nonlinear system stochastic resonance in the neighbourhood of bifurcation point

This paper studied the characteristics of stochastic resonance in the neighborhood of bifurcation point of two nonlinear dynamic systems, the pitchfork bifurcation system and FitzHughNagumo (FHN) cell model. The results of research show t hat the two nonlinear dynamic systems have the same bifurcation characteristic o f transition from one to two attractors (or from two to one attractors) when the bifurcation of each system occurs, that is, in the neighborhood of the bifurcat ion point there exist attractors before and after bifurcation on the both sides of the bifurcation point. Under the perturbation of noise, a transition may occu r between the two coexisting attractors on the right side of the bifurcation poi nt, in a way like the mechanism of traditional stochastic resonance; moreover,an other transition may also occur among the three attractors (one before bifurcati on and two after it) on two sides of the bifurcation point, which can induce sto chastic resonance alone. When the two types of transitions occur, the stochastic resonance induced by the second type of transition continues in a wide intensit y range of noise, which causes the first type of transition; and the stochastic resonance induced by the first type of transition stops in a rather small range of the noise intensity,and then causes the second type of transition.

Head Injury and Antisocial Personality Features in a Sample of Juvenile Detainees

Previous research has reported high prevalence rates of head injury amongst juvenile justice involved youth and relations between head injury and different forms of offending. However, little is currently known about the extent to which head injury is associated with antisocial personality features – characteristics that are strongly correlated with adult antisocial personality disorder symptomatology. The current study aimed to address this void in the existing body of research by analyzing a longitudinal sample of juvenile detainees (N = 881) to examine the relationship between head injury during childhood or early adolescence and a wide range of antisocial personality features in late adolescence. Results from a series of logistic regression models reveal that head injury is associated with impulsivity and aggression more than other features of antisocial personality. The implications of these results for juvenile justice intervention programming and avenues for future research are discussed.
Extended finite element method for modeling three-dimensional crack problems

The extended finite element method(XFEM) is a new numerical method for modeling strong as well as weak discontinuities within a standard finite element framework.The computation mesh in XFEM is independent of the discontinuities,such that re-meshing for moving discontinuities can be overcome.An extended finite element method for modeling three-dimensional crack problems is described.In order to model the crack discontinuity,a Heaviside step function and the two-dimensional asymptotic crack-tip displacement fields are added to the finite element approximation for the local enrichment by using the framework of partition of unity.The crack is described with two level set functions.The nonlinear contact conditions between the crack faces are resolved with the linear complementary method;the iterative procedure is avoided.Stress intensity factors of crack front are obtained with two-point displacement extrapolation method.Three examples for three-dimensional elastostatic problems are given;the results show that the method can obtain high accurate stress intensity factors and effectively treat the contact problem between crack surfaces,and the combination of the XFEM and linear complementary method has wonderful practical merits for solving discontinuous problems.
Central Oxygen Venous Saturation and Mortality in Patients Undergoing Coronary Artery Bypass Grafting

Purpose Central venous oxygen saturation (ScvO2) has been reported as a prognostic marker of in-hospital mortality when it is below 60% in certain situations. Nevertheless, it has not been widely reported in patients undergoing coronary artery bypass graft (CABG). The study determined the association between ScvO2 and in-hospital mortality in patients undergoing CABG in a high-complexity health institution in Santiago de Cali, Colombia. Patients and Methods A retrospective cohort study was conducted with patients undergoing isolated CABG. The subject sample included 515 subjects aged 18 years or older. Exposure was defined as ScvO2 <60% upon admission to the intensive care unit (ICU) following surgery. The major outcome was mortality rates after 30 days. Furthermore, exposure variables were measured at preoperative, intra-operative, and postoperative time points. Results A total of 103 exposed and 412 unexposed subjects were included. The final model revealed a higher mortality risk in individuals with ScvO2 <60% upon ICU admission compared with those with higher saturation levels (relative risk 4.2, 95% confidence interval: 2.4–7.2; p = 0.001). Values were adjusted using variables such as age (>75 years), low socioeconomic stratum, chronic kidney failure before surgery, unstable angina before surgery, ischemia time (>60 min), and intra-operative inotrope use. The primary cause of death was cardiogenic shock (54.7%), followed by sepsis (25.0%) and postoperative bleeding (17.2%). Conclusion The study identified an association between ScvO2 <60% and in-hospital mortality in patients undergoing CABG.
Comparing the Effect of Geranium Aromatherapy and Foot Reflexology on Fatigue and Daily Activities of Patients Undergoing Hemodialysis: A Randomized Controlled Trial

Background: Fatigue is the most common symptom described by patients undergoing hemodialysis. Foot reflexology and then aromatherapy, among the types of complementary medicine, are the most frequently used intervention to control fatigue in patients undergoing hemodialysis. Objectives: The purpose of the present study is to compare the effect of aromatherapy with geranium essential oil and foot reflexology on Fatigue and daily activities of patients undergoing hemodialysis referred to the Hemodialysis Centers of Dezful University of Medical Sciences in 2019. Methods: This randomized controlled clinical trial was conducted on 90 patients (30 patients in the geranium essential oil aromatherapy intervention group, 30 patients in the foot reflexology intervention group, and 30 patients in the control group). After the consent form was completed by the patient, Visual Analogue Fatigue Scale (VAFS), Piper Fatigue Scale (PFS) and Nottingham Extended Activities of Daily Living (NEADL) scale were completed for patients before the intervention and then four weeks after the intervention. Data analysis was carried out using descriptive statistics (prevalence, mean and standard deviation) and inferential statistics (one-way analysis of variance and least significant difference (LSD) post hoc test, t test) in SPSS version 16. Results: There was a statistically significant difference between the pre-test and post-test PFS and NEADL scores in the foot reflexology group. After foot reflexology, the mean fatigue scores decreased significantly (P < 0.001) and the mean activities of daily living (ADL) scores increased significantly (P < 0.001). There were no changes in fatigue and ADL scores in the geranium essential oil aromatherapy and the control groups after the intervention (P > 0.05). Conclusions: Foot reflexology can be used as an effective nursing intervention to reduce fatigue and increase ADLs of patients with chronic kidney failure and undergoing hemodialysis treatment.

DEVELOPMENT OF ORGANOMETALLIC COMPOUNDS OF SCHIFF BASES WITH DIVERSE APPLICATIONS

Schiff bases are well-known synthetic compounds which are known to be used as drug molecules for various pharmacological and therapeutic applications. These compounds were prepared synthetically in simple steps and used against various diseases as antimicrobial agents, anti-HIV agents, antitumour agents, industrial applications like enzymatic reactions, catalytic activity. However, considering the various challenges posed by different microorganisms to the conventional Schiff bases, medicinal chemists have initiated the novel approach by synthesizing the new lead compounds for different pharmacological activities containing complexes of Schiff bases with different metals as these are new compounds and potent molecules due to duo combination with metals. This combination has gained prominence now a days against those diseases for which Schiff bases are becoming ineffective, such as cancer due to resistance and irrational usage. Hence, this review is an attempt to throw some light on the recent developments in the world of new drug molecules comprising of Schiff bases complexes with different metals like Copper (Cu), Palladium (Pd), Aluminium (Al), gold (Au), Silver (Ag) etc.
Molecular dynamics simulations of ASC09, ritonavir, lopinavir and darunavir with the COVID-19 protease

Given the novelty of SARS-CoV-2 infection (COVID-19), and the lack of proven therapies, a wide variety of strategies are being employed to combat COVID-19 pandemic. Many of these emerging strategies rely on repurposing existing drugs and their mechanistic approaches that are effective against either similar viral infections or the serious symptoms that are caused by COVID-19. The recently solved issue of the crystal structure of the COVID-19 protease has made elucidating the structure–activity relationship feasible. The interaction of ASC09, ritonavir, lopinavir and darunavir with COVID-19 protease was simulated using the Site Finder module, molecular docking and molecular dynamics (MD). Analysis of the MD trajectories has provided the ligand/receptor interaction fingerprints, combining information on the crucial receptor residues and frequency of the ligand/residue contacts. The contact frequencies and the contact maps suggest that for all studied antiviral drugs, the interactions with Gln 107, Pro 108, Gln 110 and His 246 are an important factor for drugs affinities toward the COVID-19 protease. However, the leading interactions with Arg 105, Phe 134, Glu 240, Thr 243, Asp 245 or Phe 294 also significantly contribute to the ligand/receptor interplay and, in particular, differentiate their binding affinities toward COVID-19 protease.
A Posit based Handwritten Digits Recognition System

: The automated handwritten digit recognition system has numerous applications. It is required to be performed for address interpretation in postal services, bank cheque processing, or digitization of paper documents. But, for computers to recognize the handwritten numeral images is a challenging task. Various techniques have been utilized for this purpose, like convolutional neural networks architectures. This paper presents a novel design of a Posit-based handwritten digits recognition system, one of the convolutional neural network applications. Posit, a universal number system is a substitute of floating point arithmetic format and is hardware friendly. Herein, LeNet and ResNet-18 based HDRS (Handwritten Digits Recognition System) architecture is used for training and inference of model. The parameters obtained after training were converted to (8,0) Posit number system. Training of LeNet and ResNet-18 based HDRS has been done over the MNIST database, an open-source database for handwritten digits recognition. The proposed Posit (8, 0) based HDRS provides comparable accuracy to traditional floating point and fixed point based HDRS.
D- And A- Optimal Orthogonally Blocked Mixture Component-Amount Designs via Projections

Mixture experiments are usually designed to study the effects on the response by changing the relative proportions of the mixture ingredients. This is usually achieved by keeping the total amount fixed but in many practical applications such as medicine or biology, not only are the proportions of mixture ingredients involved but also their total amount is of particular interest. Such experiments are called mixture amount experiments. In such experiments, the usual constraint on the mixture proportions that they should sum to unity is relaxed. The optimality of the design strictly depends on the nature of the underlying model. In this paper, we have obtained D- and A- optimal orthogonally blocked mixture component-amount designs in two and three ingredients via projections based on the reduced cubic canonical model presented by Husain and Sharma [7] and the additive quadratic mixture model proposed by Husain and Parveen [3], respectively.
The existence of weak solutions to immiscible compressible two-phase flow in porous media: The case of fields with different rock-types

We study a model describing immiscible, compressible two-phase flow, such as water-gas, through heterogeneous porous media taking into account capillary and gravity effects. We will consider a domain made up of several zones with different characteristics: porosity, absolute permeability, relative permeabilities and capillary pressure curves. This process can be formulated as a coupled system of partial differential equations which includes a nonlinear parabolic pressure equation and a nonlinear degenerate diffusion-convection saturation equation. Moreover the transmission conditions are nonlinear and the saturation is discontinuous at interfaces separating different media. There are two kinds of degeneracy in the studied system: the first one is the degeneracy of the capillary diffusion term in the saturation equation, and the second one appears in the evolution term of the pressure equation. Under some realistic assumptions on the data, we show the existence of weak solutions with the help of an appropriate regularization and a time discretization. We use suitable test functions to obtain a priori estimates. We prove a new compactness result in order to pass to the limit in nonlinear terms. This passage to the limit is nontrivial due to the degeneracy of the system.
Determine of Nitrogen Dioxide Emissions over Khuoms City in Libya Using MODIS and TROPOMI Satellites

Sentinel-5 Forerunner (S-5P), carrying the TROPO round recognition Instrument (TROPOMI) nadir-viewing crystal spectroscope, is that the beginning mission of the Copernicus Program committed to the recognition of air quality. Within the given data the TROPOMI tropospheric gas (NO2) level-2 (L2) item has been substantially over capably sullied urban districts by comparison with coincident high-resolution MODIS remote detecting observations (1 km×1 km). Satellite products may be ideally surveyed backed by 5 bands, as an out-measured amount of lackey pixels may be completely mapped within the system of the S-5P approval campaign over Khumos town in Libya. Each piece of information was taken in 2020 over a power station in Khuoms city in Libya, for mapping the level dissemination of tropospheric NO2, each image pixel was fully covered by approximately 370 to 700 nm for visible spectrum (MODIS and TROPOMI pixels). The TROPOMI and MODIS NO2 emissions were similar in concept, the regression analysis of both data with well correlated (R2= 0.87), and there is a negative relationship (−0.03×1015 molec/cm2) recorded when clouds and dust were prevalent over the study area. From the results obtained from MODIS and TROPOMI data, nitrogen dioxide emissions were high to medium (6.6 to 3.2×1015 molec/cm2) at their source and five kilometers from the source, while the rest of the study area ranged from (2.2 to 0.15×1015 molec/cm2) low to very low.
Complete moment convergence for arrays of rowwise NSD random variables

In this paper, the complete convergence and complete moment convergence for arrays of rowwise negatively superadditive dependent (NSD, in short) random variables are investigated. Some sufficient conditions to prove the complete convergence and the complete moment convergence are presented. The results obtained in the paper generalize and improve some corresponding ones for independent random variables and negatively associated random variables.
Analysis of a degenerate biofilm model with a nutrient taxis term

We introduce and analyze a prototype model for chemotactic effects in biofilm formation. The model is a system of quasilinear parabolic equations into which two thresholds are built in. One occurs at zero cell density level, the second one is related to the maximal density which the cells cannot exceed. Accordingly, both diffusion and taxis terms have degenerate or singular parts. This model extends a previously introduced degenerate biofilm model by combining it with a chemotaxis equation. We give conditions for existence and uniqueness of weak solutions and illustrate the model behavior in numerical simulations.
3D Segmentation by Spectral Clustering Using Shape Index

The 3D segmentation is a required pretreatment for many applications of 3D processing objects (Search by content, compression, animation, etc.). The design of a segmentation algorithm must take into account the purpose of the algorithm and the application domain to which it is intended. We propose in this paper a new approach to construct the recursive spectral clustering technique using a similarity matrix. This approach is based on the shape index values of adjacent faces and a hierarchical segmentation by optimal recursive cuts. The experimental results obtained are very encouraging and have allowed us to evidence the effectiveness of our approach for segmentation of 3D objects.
Tax Avoidance in Relationship on Capital Intensity, Growth Opportunities, Financial Distress and Accounting Conservatism

Tax avoidance is an act of legal tax avoidance, but in this case the state suffers losses from this action. There are several factors that affect tax avoidance including capital intensity, growth opportunities, financial distress, and accounting conservatism. This type of research uses quantitative research with company objects that are members of the Jakarta Islamic Index 70. Data sources use secondary data listed in the company's financial reports for the 2018-2021 period. A total of 105 research data were tested using the SPSS version 25 application. The test results showed that only capital intensity had a negative and significant effect on tax avoidance, while other variables had no effect on tax avoidance. The test results show that tax avoidance tends to be influenced by factors that affect cost reduction.
