Down syndrome is one of the most common chromosomal disorders in pediatrics characterized by variable intellectual disability, generalized joint laxity, and hypotonia that compromises their function causes a delay developing gross motor skills, poor balance, coordination. Thus, this study aims to determine current yet effective treatment approaches improve balance population. The studies were e...

The aim of this work is to present the mathematical description of a detailed multivariate population balance model to describe the structure and composition of silica nanoparticles. Silica nanoparticles are formed by the interaction of silicic acid monomers (Si(OH)4)in the gas-phase. A detailed numerical study of a stochastic particle algorithm for the solution of the multidimensional populati...

OBJECTIVE to evaluate spinopelvic balance using the pelvic incidence, sacral slope and pelvic tilt among patients with lumbar disk hernias who underwent surgical treatment. METHODS thirty patients at the spinal services of Hospital Santa Casa de Misericórdia de Vitória and Hospital Vila Velha were evaluated by measuring their spinopelvic balance from the angles of pelvic tilt, sacral slope an...

Investigation of multiphase systems generally requires the solution of the population balance equation; bubble columns, crystallisation and precipitation reactors are some examples of important industrial applications. As mixing also plays an important role in determining phase interactions, often the population balance has to be included in a Computational Fluid Dynamics (CFD) code. This can b...

For a population of identical one compartment systems with daily inputs which are random samples from a stationary distribution the mean of the daily balance (balance = input minus excretion) taken over the population of compartments or over days for one compartment is linearly dependent on input with a slope which is independent of the distribution of the inputs and an intercept which depends ...

Background: Falls amongst elderly people are often associated with fractures. Training of balance and physical performance can reduce fall risk; however, it remains a challenge to identify individuals at increased risk of falling to whom this training should be offered. It is believed that fall risk can be assessed by testing balance performance. In this study a test battery of physiological pa...

We reanalyze some of the data used by Klots to establish an experimental basis for the claim by Gspann that clusters have a highest temperature in molecular beams. The value of this temperature is given by the evaporative activation energy and a dimensionless parameter, called the Gspann parameter. The value of the Gspann parameter we derive from the data is higher than the value found by Klots...
