Experimental Characterization of Recycled Aggregate Concrete
Authors: NAOUAOUI Khaoula , BOUYAHYAOUI Azzeddine , CHERRADI Toufik 
Published: December 2019

The field of construction is evolving rapidly over the last decade. This is justified by the evolution of human activity in various fields mainly tourism, industry … and the aging of several buildings which implies a renovation or a demolition/re-construction. These construction activities involve a large need for aggregates for new construction and a large tonnage of waste from demolitions.
In order to remedy this, various stakeholders in the field (suppliers, cement works, research centers, etc.) have valued recycled aggregate concrete (RAC).
Recycled aggregates concrete is considered a new type of concrete based on the use of aggregates retrieved from the demolished structures instead of natural aggregates. This replacement affects, for sure, the characteristics of the concrete produced specially the mechanical properties.
Developed countries have made a great progress in normalizing the use of recycled aggregates (RA) in concrete implementation as a result of many studies done since 80’s. In Morocco, recycled aggregates do not have any specific standards, and is used mainly in roads and pavements construction. Even if it’s not normalized this use is not recent, in 1999 during the rehabilitation of the expressway road of Casablanca which was severely damaged on both channels, the authorities have opted for the reuse of aggregates instead of reloading the existing pavement with a new one.
The study is based on the use of recycled concrete crushed from an old building in Rabat- Morocco as aggregates and compared it with naturel aggregates from Morocco to determinate the effect of this replacement on several characteristics of concrete.
This article is aiming to investigate experimentally the effect of RA in concrete using different replacement levels, different types of adjuvant and different percentages of it.
The results show that over 30% of replacement, the compressive strength decreases considerably for basic concrete.
In order to increase the compressive strength for the RAC with a percentage of replacement over 50%, we used different types of additives (Plasticizer, superplasticizer and new generation superplasticizer) and different percentage of it (0.5%, 1% and 1.5%): We concludes that, for our case, the add of plasticizer gives the best result and that the 1% replacement is the optimum percentage.
The tests done on RCA made by plasticizer with different replacement level confirm the results without plasticizer:
Compressive strength decreases when the replacement percentage increases.

Published: December 2019

Abstract
Aims The main purpose of this article is to conduct audit of clinical profile and outcomes of patients presenting with acute variceal bleed in a tertiary care hospital.
Methods and Material This was a retrospective study of patients presenting with variceal bleed in a tertiary care center. Data were generated through a computerized electronic record system. Data of patients admitted for acute variceal bleed from August 2018 to December 2018 were collected and considered for analysis. Statistical analysis was done using the software Statistical Package for the Social Sciences (SPSS) 22.0 version.
Results Overall, 107 cases were analyzed. In 89.7% (96) cases, cirrhosis of liver was a cause of variceal bleed. Besides, 77.6% (83) patients had large esophageal varices. Five patients (4.7%) required glue injection. Rebleed rate in present study was 0.9%. Mortality due to variceal bleed was 9.3% (10). Acute rebleed (p = 0.002), low mean arterial pressure (MAP; p = 0.001), low platelet count (p = 0.001), high serum creatinine (p = 0.001), high serum total bilirubin (p = 0.001), high international normalized ratio (INR; p = 0.001), and higher model for end stage liver disease (p = 0.001) were associated with increased risk of mortality. Door to endoscopy time (<12 hours or 12–24 hours) did not affect the mortality rate (p = 0.699). Terlipressin given 24 hours after endotherapy is equally effective as terlipressin given 5 days after endotherapy.
Conclusion Mortality due to acute variceal bleed can be reduced with timely intervention. Low MAP, low platelet count, higher serum bilirubin and creatinine, and higher INR are predictors of increased mortality due to variceal bleed. Endoscopy done within 12 to 24 hours of presentation did not affect the outcome.
CBD Stone Formation Over Migrated Surgical Clip: A Rare Complication Developed Fourteen Years after Laparoscopic Cholecystectomy
Authors: Shah Parth , Rathi Pravin 
Published: December 2019

AbstractLaparoscopic cholecystectomy (LC) is currently the treatment of choice for symptomatic gallstones. Migration of surgical clips into common bile duct (CBD) is a rare complication after LC. Migrated surgical clips may lead to further complications like cholangitis, choledocholithiasis. We report a rare case of CBD stone formed over migrated surgical clips, 14 years after LC. A 41-year-old male with history of LC 14 years back, presented with repeated episodes of biliary colic. Computed tomography (CT) scan abdomen showed CBD stones with metallic foreign bodies and prominent CBD. Patient was managed successfully with endoscopic retrograde cholangiopancreatography. Patient became asymptomatic thereafter. This case is a rare complication developed after a very commonly performed surgery.
THE NATURE OF AUSTRALIA ANTIGEN AND ITS RELATION TO ANTIGEN-ANTIBODY COMPLEX FORMATION
Authors: Blumberg Baruch S. , Millman Irving , Sutnick Alton I. , London W. Thomas 
Published: December 2019

There is considerable data to support the hypothesis that Australia antigen is an infectious agent that causes hepatitis in man.
(a) Association with acute viral hepatitis.
(b) Association with chronic hepatitis.
(c) Virus-like appearance under the electron microscope (200-A particles).
(d) Transmission of Au(1) from man to man.
(e) Transmission and passage of partially purified Au(1) to an animal host (infant African green monkey).
(f) Localization [with fluorescent anti-Au(1)] of Au(1) in the nuclei of liver cells of patients with hepatitis and/or Au(1) in their blood.
(g) Distribution of Au(1) in institutions, disease groups, and populations is consistent with the distribution of an infectious agent.
(h) RNA identified in Au(1) particles isolated from blood.
(i) Apparent replication of Australia antigen in tissue cultures of human liver cells.
There is also considerable evidence that Australia antigen has many of the characteristics of a serum protein polymorphism. Since neither of these hypotheses has been rejected they can be combined to make a third hypothesis, namely, that Australia antigen is an infectious agent which causes hepatitis in some people infected with it and that it has the characteristics of an (inhertied) serum protein polymorphism. We propose calling agents of this postulated class "Icrons."

SKIN FERMENTS
Authors: Sexsmith Edna , Petersen William F. 
Published: December 2019

That a definite change in the reactivity of the skin takes place during the transition from infancy to childhood has been repeatedly noted. Rolly (5), working with a variety of bacterial toxins, found that infants did not react, but that reactions occurred with advancing age. Similarly Tenner (6), using Witte's peptone, colon bacilli, and tuberculin observed that at about the period that the skin of children became increasingly sensitive to tuberculin, a corresponding reactivity was manifest toward the other antigens. It seems possible to us that this phenomenon is related to the alteration in the ferments of the skin that takes place during the transition period. Thus while the protease of the adult type of skin causes a definite autolysis, that of the fetal skin does not, the synthetic potential evidently predominating. Of greater significance seems to be the fact that the skin of the young animal contains peptidase to a considerable amount, while the adult skin seems to be without this ferment activity.
If we assume that the disintegration of the native protein of the antigen is essential in eliciting certain skin tests, it would seem probable that the splitting would be less apt to take place in the young skin in which the lytic effects of the ferments are relatively suppressed. On the other hand, the young skin, containing peptidase, would be able to digest rapidly any antigen consisting of partially hydrolyzed proteins—as tuberculin—and in this way detoxicate and remove the noxious material. From these considerations the undoubted alteration of the skin reactivity taking place after infancy seems definitely correlated with changes in the proteolytic ferments. In how far they enter into and alter the specific reactions cannot be determined from the limited data so far available.
Of the other ferments, the lipases, as pointed out by Porter, are possibly of importance in the resistance of the skin to tuberculous infection. It will be observed from the table that the activity of these skin ferments is less manifest in their action as esterases, on ethyl butyrate, than on the neutral fats used, oleic oil and butter fat, in this way differing from the activity of the serum. The relative resistance of the skin to tuberculous infection can, however, hardly be due to the activity of the lipase alone, for it must be kept in mind that the lepra bacillus, also rich in lipoids, is enabled to proliferate well within the epithelial tissues.

Simulation of mechanical behaviour of the proximal femur as a poroelastic solid using particles

Published: December 2019

Abstract
Full understanding of the mechanical behaviour of living bone is the key to solving many important problems of modern orthopaedics and arthroplasty. An important role in the study of the mechanical behaviour of living bone belongs to the development and use of comprehensive numerical models. In this work, we model the mechanical behaviour of the proximal femur as a 3D poroelastic solid consisting of the interior cancellous part and the outer cortical part. For simplicity, both parts are assumed isotopic linear poroelastic material. However, they have different values of porosity, fluid content and elastic properties, which are taken from literature. For computer simulation, we used the so-called movable cellular automaton method, which is a representative of simply deformed discrete elements i.e. computational particle mechanics. The method allows simulating dynamics of the elastic skeleton deformation and viscous fluid flow in the skeleton pores according to Biot’s theory of linear poroelasticity. Using the model developed we study the mechanical behaviour of the proximal part of the femur in compression with different rate of loading and different permeability. The results obtained for both saturated and drained bones are discussed.
Generating efficient basis sets for unbounded domains
Authors: Mumtaz F , Alharbi F H 
Published: December 2019

Abstract
The treatment of the problems involving unbounded domains (UDs) with vanishing boundary conditions is always challenging. For spectral methods, in particular, very limited basis sets are commonly used for such domains, in which the ranges of the decay rates with acceptable computational efficiency, are very small. Furthermore, maintaining high level of analyticity becomes burdensome. Developing efficient mapped basis tailored for such problem is one of the main strategies to overcome these difficulties. In this work, we present a technique to generate efficient basis sets for UDs. This approach allows using basis sets defined for bounded domains (BDs) for problems in UDs, and hence, providing more freedom to choose from a variety of basis sets. To ensure computational efficiency, the designed transformations cover a wide range of decay rates and allow solving integrals analytically. The method is applied to solve many differential equations encountered frequently in many physics related problems. The results illustrate the efficiency of the developed technique and mapped basis sets.
Stressed state of a steel construction working in hydrogen containing environment
Authors: Emel’yanov I G , Polyakov A A , Hodak A S 
Published: December 2019

Abstract
An approach is proposed to solve the problem of estimating the stress state of a shell structure loaded with a thermomechanical load and in contact with a hydrogen-containing medium. The stress state of the steel housing of the diffusion apparatus for the production of highly pure hydrogen was determined. The object of study is presented in the form of a composite shell of rotation, loaded by internal pressure and operating at elevated temperatures. The purpose of the work is to determine the stress state of the shell at normal and elevated pressure, taking into account changes in the mechanical properties of the combined effect of temperature and hydrogen. In the general case, the task of calculating such a structure under given operating conditions is related. In the phenomenological approach, the relationship between thermal diffusion and mechanical problems is manifested in a change in the parameters of the sample deformation diagram with increasing temperature and hydrogen concentration. The integration of differential equations of a boundary value problem for a shell under pressure is performed by the discrete orthogonalization method S.К. Godunov.
Canonical quantization of anisotropic Bianchi I cosmology from scalar vector tensor Brans Dicke gravity
Authors: Ghaffarnejad Hossein 
Published: December 2019

Abstract
We applied a generalized scalar-vector-tensor Brans Dicke gravity model to study canonical quantization of an anisotropic Bianchi I cosmological model. Regarding an anisotropic Harmonic Oscillator potential we show that the corresponding Wheeler de Witt wave functional of the system is described by Hermit polynomials. We obtained a quantization condition on the ADM mass of the cosmological system which raises versus the quantum numbers of the Hermit polynomials. Our calculations show that the inflationary expansion of the universe can be originate from the big bang with no naked singularity due to the uncertainty principle.

Published: December 2019

Abstract
The implementation of the deep space expeditions to the outer Solar system is the one of main priorities of modern astrodynamics. One of the irritating factors for this is the probability of the life determination in the underground ocean at the Jovian icy moon Europa. In that regard the realization of the cosmic projects using the spacecraft — orbiters around the Jovian Galilean Moons and especially the descent modules implementation on their surface is one of the basic focuses of the current international cosmic space researches collaboration. The mission design of such cosmic projects must be executed using new advanced methods for their planning: Low Energy Tours exploring, Favourable Total Radiation Doze of the spacecraft (SC) provision, and tolerable maintenance of the SC’s Time of Flight during the Jupiter system phase. Furthermore, the saving character of the trajectory design for the artificial satellite of the Galilean moon necessary required the smallness of the SC’s velocity relative this moon, i.e. the smallness of the SC’s hyperbolic velocity excess vector. In this work multibody bunch adaptive synthesis algorithms to overcome ballistic determinism expressed by existing of the integral of Jacobi in the basic CR3BP (circular restricted three body problem) are developed. It is shown that the diversity of the gravity of the ensemble in the Jovian system, not only complicates the accurate ballistic mission analysis, but, when its multibody effective use, allowing you to tailor flowed algorithms for the constructing scenarios of gravity assist maneuvers for interplanetary missions design, including circumvention of dangerous radiation areas, as well as landing at selected Galilean moon at a reasonable cost, resources and time.

Published: December 2019

Abstract
The article explores the methods of mathematical and computer modelling of the nonlinear dynamics of particle beams in cyclic accelerators in terms of the matrix formalism using both numerical and symbolic representations of the corresponding nonlinear differential equations. This paper shows how the matrix formalism approach allows the use of modern computational algorithms and artificial intelligence methods for more efficient and flexible modelling of particle beam dynamics in accelerators. Also, the article proposes a method of representing control elements using LEGO objects, which makes it possible to increase the efficiency of using control elements from a computational point of view and to facilitate the process of modelling particle dynamics.
Reputation in Majority Rule Model leading to democratic states
Authors: Oliveira Leonardo S. , Rodrigues Anderson C. , Forgerini Fabricio L. 
Published: December 2019

Abstract
We study the Majority Rule (MR) model, a sociophysics model developed to describe how a group of agents with initial different opinions can reach consensus. At each instant of time, a group is selected at random and discuss among each other. After the discussion, all members of this discussion group follow the majority opinion. The number of agents in the discussion group is not fixed and it is selected each instant of time from a Gaussian distribution. The system dynamics stops when only one opinion survive. In this work we introduced in the MR model a ‘reputation’ for each agent, a weight to be considered in the system dynamics. Our results show that the introduction of reputation leads the system to a steady state in which not every agent on the system have exactly the same status, but a majority of them sharing the same opinion. In addition, our model with the inclusion of reputation do not show the critical point usually observed. Instead we have obtained the critical point pc
= 1, in contrast with the standard Majority Rule model.
Novel approach for accurate detection of contaminating human mitochondrial DNA in next-generation sequencing data
Authors: Ishiya Koji , Ueda Shintaroh 
Published: December 2019

AbstractDNA molecules are degraded after the death of an organism. However, the degree and rate of DNA degradation enormously vary depending on environmental conditions, such as temperature or humidity, which greatly affect DNA preservation. Most samples excavated in warm, humid, or dry areas are often poorly preserved samples with from<0.1%-1% endogenous DNA. In these degraded samples, the contamination by exogenous DNA remains a potential challenge, no matter how much effort is made to prevent it. For an accurate DNA sequence analysis, quality control must be thoroughly performed, using the mitochondrial DNA as an indicator of exogenous DNA contamination. Here, we propose a practical approach for detecting exogenous human mitochondrial macro haplogroups, and discuss the effectiveness of this approach using simulated data. Our approach is based on the Bayes classification, which is a supervised machine learning algorithm, and it can detect a contaminating macro haplogroup in high-throughput sequencing data. This approach can help validate the quality of high-throughput sequencing data from possibly contaminated or degraded human samples.
