Advances in mathematical modelling of biofilm structures
(2007)Biofilms are found everywhere in natural waters forming complex microbial communities, playing an important role in ecosystem processes in streams and lakes and making their characterization a major research question. ... -
Biophysical characterization of V3-lipopeptide liposomes influencing HIV-1 infectivity
(2007)The V3-loop of the HIV-1 gp120 alters host cell immune function and modulates infectivity. We investigated biophysical parameters of liposome constructs with embedded lipopeptides from the principle neutralizing domain of ... -
Chirality transfer from a 3D macro shape to the molecular level by controlling asymmetric secondary flows
(2022)Homochirality is a fundamental feature of living systems, and its origin is still an unsolved mystery. Previous investigations showed that external physical forces can bias a spontaneous symmetry breaking process towards ... -
Comparison of physiological and post-endovascular aneurysm repair infrarenal blood flow
(2017)Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms results in redirection of blood through the deployed endograft (EG). Even though EVAR is clinically effective, the absolute flow restoration is not warranted. ... -
Essential oil-in-water microemulsions for topical application: structural study, cytotoxic effect and insect repelling activity
(2022)Essential oils (EOs) extracted from aromatic plants have been well recognized for their insect repellent properties. Although EOs are effective when freshly applied, their protective effect usually dissipates quickly due ... -
Flood inundation mapping sensitivity to riverine spatial resolution and modelling approach
(2016)An innovative approach in the investigation of complex landscapes for hydraulic modelling applications is the use of terrestrial laser scanner (TLS) that can lead to a high-resolution digital elevation model (DEM). Another ... -
Haemodynamic performance of AFX and Nellix endografts: A computational fluid dynamics study
(2018)OBJECTIVES The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated ... -
Hydrodynamics and near trapping effects in arrays of multiple elliptical cylinders in waves
(2018)The purpose of the present study is the investigation of the hydrodynamic interactions induced by arrays of elliptical cylinders subjected to regular waves. The solution methodology employs linear potential theory and is ... -
Magnetic field effect on the cooling of a low-Pr fluid in a vertical cylinder
(2010)Results of direct numerical simulations are presented for the transient and turbulent natural convection cooling of an initially isothermal quiescent liquid metal placed in a vertical cylinder in the presence of a vertical ... -
Near trapped modes in long array of truncated circular cylinders
(2019)The purpose of this article is to investigate near trapped-mode occurrences by arrays of truncated cylinders. The basic question that this article tries to answer is whether near trapped modes (peak loading wave numbers) ... -
A novel method for the automatic extraction of quality non-planar river cross-sections from digital elevation models
(2020)Flood simulation and hydrodynamic modeling of river flow require a dense sequence of river cross-sections. These cross-sections should be perpendicular to the flow path and are usually obtained through an in-field survey ... -
Numerical Investigation of Wind Driven Circulation and Horizontal Dispersion in the Surface Layer of a Re-flooded Shallow Lake
(2016)The re-flooded lakes with unique natural and cultural values that are under threat from anthropogenic pressure, consist a very important section of fresh water resources management in the Mediterranean. Lake Karla, positioned ... -
Optimum design of the entrance of a fishpond laterally to the main stream of an open channel
(2017)In this study, the optimum design of the entrance of a fishpond laterally to the main flow of an open channel was investigated numerically and experimentally. The flow characteristic measurements were realized with the PIV ... -
Quantification of normal CSF flow through the aqueduct using PC-Cine MRI at 3T
(2012)Quantification of cerebrospinal fluid (CSF) flow through the cerebral aqueduct is of paramount importance in patients with hydrocephalus. The purpose of this study was to evaluate the normal CSF flow measurements at three ... -
Study of water renewal and sedimentation of a square harbor encapsulated in a coastal front with seawalls due to wind-induced hydrodynamic circulation
(2021)In the current study in the middle of a coastal zone, a harbor basin in the form of a square area recessed to the front is considered. A breakwater of variable length and position offers protection from waves. The water ... -
Tribological design of hydrodynamic sliding journal bearings - formulating new functional charts
(2005)Purpose - This paper aims to introduce an innovative methodology for the determination of operational characteristics of journal bearings (j-bs) through using new type charts based upon a numerical solution of the Reynolds ...
