introduction: educational justice is a process by which all those involved in education are pondering and seeking to establish it in their regulatory environments. this study aimed to investigate effective factors in an ideal educational justice and the current condition of educational justice from the students’ viewpoint and ultimately increase the awareness and understanding of authorities an...

optimization problem in a Banach space. The assumption that the strengthened Legendre– Clebsch condition holds is crucial. In particular, we refer the reader to Milyutin & Osmolovskiı̌ (1998) where the importance of this condition is fully explained. In this paper, we consider a fixed-endpoint optimal control problem with equality control constraints and provide a new set of sufficient condition...

A classical model of Brownian motion consists of a heavy molecule submerged into a gas of light atoms in a closed container. In this work we study a 2D version of this model, where the molecule is a heavy disk of mass M ≫ 1 and the gas is represented by just one point particle of mass m = 1, which interacts with the disk and the walls of the container via elastic collisions. Chaotic behavior of...

Some practitioners use advanced lipoprotein analysis with the goal of better predicting risk and individualizing lifestyle and drug therapy for cardiovascular prevention. Unfortunately, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) particle number and size, other lipoprotein subfractionation, apolipoproteins B and A, and lipoprotein(a) have not yet met current standards for b...

Serum pepsinogen I and II levels have recently become popular as indicators of atrophic gastritis in epidemiological studies. Previous studies show a significant association between serum pepsinogen levels and endoscopically diagnosed atrophic gastritis. This study assesses the level of agreement between the degree of atrophic gastritis as assessed by endoscopic examination and by serum pepsino...

Time based observations are the linchpin of improving predictions in any dynamic data driven application systems. Our predictions are based on solutions to differential equation models with unknown initial conditions and source terms. In this paper we want to simulate a waste spill by a water body, such as near an aquifer or in a river or bay. We employ sensors that can determine the contaminan...

The Riemann-Lanczos problem for 4-dimensional manifolds was discussed by Bampi and Caviglia. Using exterior differential systems they showed that it was not an involutory differential system until a suitable prolongation was made. Here, we introduce the alternative Janet-Riquier theory and use it to consider the Riemann-Lanczos problem in 2 and 3 dimensions. We find that in 2 dimensions, the Ri...

A string cosmology scenario (“pre-big-bang”) postulates that the evolution of the Universe starts from a state of very small curvature and coupling, undergoes a long phase of dilaton-driven kinetic inflation and at some later time joins smoothly standard radiation dominated cosmological evolution, thus giving rise to a singularity free inflationary cosmology. I report on recent progress in unde...

In this paper, the initial value problem for a structure floating on the surface of the sea is investigated under the assumptions of linear theory. Fourier transforms are used to connect the timeand frequency-domain representations of the coupled motion of the fluid and body. This allows the large-time asymptotics of the motion to be obtained from the singularity structure of the frequency-doma...

Hepatitis B: Hepatitis B infection can be prevented. If your work or lifestyle exposes you to the virus, we encourage you to get a Hepatitis B vaccine. If you have not had Hepatitis B vaccine, you can begin your Hepatitis B vaccine series immediately after being exposed. Hepatitis C: There is no vaccine to prevent Hepatitis C. If exposed, you must be tested regularly to make sure you have not b...
