Legal and ethical issues in robotic surgery
(2010)Aim. With the rapid introduction of revolutionary technologies in surgical practice, such as computer-enhanced robotic surgery, the complexity in various aspects, including medical, legal and ethical, will increase ... -
Leptin levels in women with polycystic ovary syndrome before and after treatment with diazoxide
(1998)Leptin, a product of the ob gene, is a 16 kDa protein which is produced by adipocytes. In humans, obesity is a common finding in women with polycystic ovary syndrome (PCOS). The role, however, of leptin in PCOS is not clear ... -
MAIZE AND LEGUMES ROOT GROWTH AND YIELD AS INFLUENCED BY ORGANIC FERTILIZATION, UNDER MEDITERRANEAN ENVIRONMENTAL CONDITIONS
(2012)Field experiments were conducted to determine the effects of green manures on growth and yield of maize crop. This study also evaluated the effects of two different composts on nitrogen fixation and growth of legume crops. ... -
Mismatch repair hMSH2, hMLH1, hMSH6 and hPMS2 mRNA expression profiles in precancerous and cancerous urothelium
(2013)Changes in the expression of the mismatch repair (MMR) genes hMSH2, hMLH1, hMSH6 and hPMS2 reflect dysfunction of the DNA repair system that may allow the malignant transformation of tissue cells. The aim of the present ... -
A model supported interactive virtual environment for natural resource sharing in environmental education
(2013)This paper introduces a realistic 3D model supported virtual environment for environmental education, that highlights the importance of water resource sharing by focusing on the tragedy of the commons dilemma. The proposed ... -
A multipurpose quality assurance phantom for the small animal radiation research platform (SARRP)
(2012)In this work, the suitability and performance of a mouse-size MOSFET (Mousefet) phantom is investigated for routine quality assurance (QA) of the small animal radiation research platform (SARRP). This Mousefet phantom is ... -
A new SOI monolithic capacitive sensor for absolute and differential pressure measurements
(2005)In the present work, a new monolithic capacitive pressure sensor is being introduced. The sensor is manufactured according to a custom, 15-step SOI process. The process primarily offers great flexibility as far as sensor ... -
The nitric oxide (NO) donor molsidomine antagonizes scopolamine and L-NAME-induced performance deficits in a spatial memory task in the rat
(2009)Nitric oxide (NO) is considered as an intracellular messenger in the brain. Its involvement in learning and memory processes has been proposed. Compounds that inhibit NO synthase (NOS), the key synthesizing enzyme, may ... -
Noise sources in miniature flugate sensors. Part II: the case of sensors with Fe77.5Si7.5B15 amorphous wire cores
(2005)As a continuation of Part I this paper is devoted to fluxgate sensors that employ Fe77.5Si7.5B15 amorphous wires as magnetic cores, with attention being paid to fluxgate miniaturization. Two types of fluxgate sensors have ... -
Non-overlapping Generation Species: Complex Prey-Predator Interactions
(2015)In this paper we study a prey-predator dynamical system suitable for species having no overlap between successive generations. Assuming that population evolves in discrete-time steps we investigate the prey refuge effect ... -
Objective biophysical findings in patients with sensitive skin
(2005)The term sensitive skin has been used to describe a clinical phenomenon of hyperreactivity of the human skin, which develops exaggerated reactions when exposed to external factors. The aim of this study was to determine ... -
On the thermodynamic stability of retained austenite in 4340 steel
(1997)The effect of retained austenite on the mechanical behavior of quenched and tempered steels depends on its thermodynamic stability against mechanically-induced martensitic transformation during loading. In this work, the ... -
Optimization methodology of turbomachines for hybrid SOFC-GT applications
(2014)The objective of this work is to suggest a method for optimizing the compressor and turbine components in hybrid SOFC-GT (Solid Oxide Fuel Cell - Gas Turbine) applications. The hybrid system evaluations are made on the ... -
Pipe Networks Risk Assessment Based on Survival Analysis
(2011)Integrated management of pipe networks should include methods for monitoring, repairing and replacing deteriorating components (usually pipes), but also methods and everyday operating practices towards a proactive risk ... -
Production capacity modeling of alternative, nonidentical, flexible machines
(2002)Analyzing the production capacity of a flexible manufacturing system consisting of a number of alternative, nonidentical, flexible machines, where each machine is capable of producing several different part types simultaneously ... -
A quasi-continuum multi-scale theory for self-diffusion and fluid ordering in nanochannel flows
(2014)We present a quasi-continuum self-diffusion theory that can capture the ordering effects and the density variations that are predicted by non-equilibrium molecular dynamics (NEMD) in nanochannel flows. A number of properties ... -
Real-time production scheduling in a multi-grade PET resin plant under demand uncertainty
(2012)We deal with the real-time production scheduling of a continuous-process multi-grade PET resin plant. The process is surcharged by sequence-dependent changeovers, sequential processing with production and space capacity, ... -
Serum interleukin-1 beta, interleukin-8 and anti-heat shock 60 Chlamydia trachomatis antibodies as markers of ectopic pregnancy
(2012)Anti-Chlamydial trachomatis (anti-CT) responses, particularly anti-heat shock 60 (Hsp60), antibodies confer a higher risk of ectopic pregnancy. With emerging evidence supporting the pivotal role of interleukin-1 beta (IL-1 ... -
A simulation-based performance evaluation of a randomized MIS-based clustering algorithm for ad hoc networks
(2014)Ad-hoc networks represent distributed systems that comprise wireless nodes which can dynamically self-organize into arbitrary and temporary network topologies, without relying on pre-existing infrastructure, and thus network ... -
