Scaling Properties of Multiplicity Fluctuations in the AMPT Model

From the events generated from the MC code of a multi-phase transport (AMPT) model with string melting, the properties of multiplicity fluctuations of charged particles in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}=\rm{~2.76 \,TeV}$ are studied. Normalized factorial moments, $F_{q}$, of spatial distributions of the particles have been determined in the framework of intermittency. Those moments are found in some kinematic regions to exhibit scaling behavior at small bin sizes, but not in most regions. However, in relating $F_{q}$ to $F_{2}$ scaling behavior is found in nearly all regions. The corresponding scaling exponents, $\nu$, determined in the low transverse momentum ($p_{\rm{T}}$) region $\le$ 1.0 GeV/c are observed to be independent of the $p_{\rm{T}}$ bin position and width. The value of $\nu$ is found to be larger than 1.304, which is the value that characterizes the Ginzburg-Landau type second order phase transition. Thus there is no known signature for phase transition in the AMPT model. This study demonstrates that, for the system under investigation, the method of analysis is effective in extracting features that are relevant to the question of whether the dynamical processes leading phase transition are there or not.Comment: 6 pages, 5 figure

Boundary Layer Flow Due To A Moving Flat Plate In Micropolar Fluid

The mathematical model for a boundary layer flow due to a moving flat plate in micropolar fluid is discussed. The plate is moving continuously in the positive x-direction with a constant velocity. The governing boundary-layer equations are solved numerically using an implicit finite-difference scheme. Numerical results presented include the reduced velocity profiles, gyration component profiles and the development of wall shear stress. The results obtained, when the material parameter K = 0 (Newtonian fluid) showed excellent agreement with those for viscous fluids. Further, the wall shear stress increases with increasing K. For fixed K, the wall shear, stress decreases and the gyration component increases with increasing values of n, in the range 0>n>1 where n is a ratio of the gyration vector component and the fluid shear stress at the wall

The Role of Organizational Culture in the Implementation of Personal Hygiene

Organisational culture is a system that continues to process in an organizational environment. The culture inherent in the organizational environment requires a long stage to become a thing that binds all elements in the organization. In nursing, organizational culture plays a vital role as a device that regulates the behaviors of nurses in carrying out their responsibilities. One of the most fundamental responsibilities is fulfilling the personal hygiene needs of inpatient clients. The c pandemic to post-pandemic conditions emphasized the need for personal hygiene as one of the essential items for the entire community and inpatient clients in hospitals. Implementing a right on target, effective and efficient personal hygiene is indispensable for a hospital to maintain service quality and increase client satisfaction. The extent to which organisational culture contributes to improving the quality of nursing services in carrying out actions to fulfil personal hygiene needs for clients needs to be investigated further. The results of this study can be a positive input for elements of hospital management to determine the direction of policies related to the implementation of nursing actions to meet the personal hygiene needs of clients. This study uses a qualitative method with a phenomenological approach. Determination of participants using purposive sampling, the number of participants is seven people, and data collection using in-depth interviews. Three themes were identified in this research, namely (1) Support System; (2) Teamwork; (3) Motivation. The effectiveness of the implementation of PH for clients must be distinct from the individual elements of the nurses themselves and the most excellent support from hospital management, both in appealing to and providing the facilities needed to improve service quality.

Numerical investigation of copper-water (cu-water) nanofluid with different shapes of nanoparticles in a channel with stretching wall: slip effects

The present study is focused on the presentation of a numerical solution for copper-water nanofluid through a stretching channel with spherical and cylindrical shape nanoparticles.The analysis of nanofluid in a channel with stretching walls under slip effects is made by introducing the conservation equation of nanoparticle volume fraction into Hamilton-Crosser’s nanofluid model. Governing partial differential equations are transformed into nonlinear ordinary differential equations by applying similarity transformation and then solved with the help of shooting method. The effects of different physical parameters on the rheology of nanofluids’ particles are presented in tabulation and pictorial representation. The study reveals that the thermal boundary layer thickness increases by increasing the solid volume fraction

Mathematical Approach for Predicting the Gross Domestic Product of Malaysia

Gross domestic product (GDP) is a monetary measure of the market value of overall final goods and services produced in a given year, and serves as a gauge of the economy’s overall health and size. The GDP prediction is significant, as it can capture and understand the future developments of a country’s economy. In this paper, three different mathematical models have been used to predict Malaysia’s gross domestic product using regressions. The models discussed in this paper are linear, exponential and parabolic regressions. In developing the models, data from year 1970 to 2014 has been employed and data from year 2015 to 2019 has been used to examine the models' accuracy. The models are then observed to identify the most appropriate to express the relationship between the years and Malaysia’s gross domestic product. In this study, it is found that the parabolic regression model is more accurate compared to the linear and exponential regression models. The parabolic regression model is also the most appropriate since it is adjusted to the real conditions of Malaysia's gross domestic product which is the main subject of this paper. Finally, it is obtained that the prediction values of GDP in Malaysia will increase for the next ten years (2020 - 2029). &nbsp; Keywords: Gross domestic product, Linear regression, Exponential regression, Parabolic regressio

Multiple Similarity Solutions Of Steady And Unsteady Convection Boundary Layer Flows In Viscous Fluids And Nanofluids

For many complex problems in convection boundary layer flow and heat transfer, multiple solutions may exist due to the nonlinearity of the differential equations, variation of geometric or fluid mechanical parameters. It is difficult to visualize the occurrence of multiple solutions experimentally, therefore mathematical computation is important to provide the details flow structure and to notice the occurrence of multiple solutions. This thesis aims to study the possible multiple similarity solutions that might exist in boundary layer flows and heat transfer. This is done by considering five different problems which are two problems in viscous fluid, one problem in nanofluid and the remaining two are in porous medium and in porous medium filled with nanofluid, respectively. For the problems in viscous fluid and nanofluid, different situations of shrinking sheet have been considered. On the other hand, vertical plate in porous medium and vertical cylinder in porous medium filled by nanofluid have also been considered. The basic governing equations in partial differential equations form for each problem are first transformed into similarity equations in nonlinear ordinary differential equations form by similarity approach. The resulting systems are then solved numerically using the shooting technique with the aid of shootlib fuction in Maple software. This technique involves Runge-Kutta method together with Newton-Raphson correction
