Minimally invasive therapies are gaining increasing attention as an alternative to standard surgical therapies in the treatment of primary hepatocellular carcinoma. These include therapies administered transcatheterally (arterial embolization, intraarterial chemoinfusion, and combination chemoembolization) and percutaneously (chemical ablation with ethanol or acetic acid, and thermal ablation w...

Most successful mobile robots rely on 2D radial laser scanners for perceiving the environment. The use of these sensors for reactive navigation has a serious limitation: the robot can only detect obstacles in the plane scanned by the sensor, with the consequent risk of collision with objects out of this plane. The recent commercialization of RGB-D cameras, like Kinect, opens new possibilities i...

Laser diffractometry was employed for size analysis in liver cell and blood cell suspensions to assess its suitability for characterizing cell populations. The method proved sensitive to detect subpopulations in liver cells (bimodal or trimodal distributions) and to quantify their volume fractions. Cell debris and aggregates of cells could also be quantified, dead cell populations recognized by...

Periodic nanohole arrangements constitute an important building block of advanced photonic devices. Aside from standard nanofabrication tools, a direct laser-based approach is introduced here, that enables single-step and point-by-point machining arrays holes with subwavelength diameters depths reaching several micrometers at the surface fused silica. The method relies on simple optical arrange...

The article deals with assessment of the suitability using a laser triangulation sensor to measure displacement in vertical axis measuring microscope. Data obtained from calibration are used for determination range which smallest measurement error occurs. Linear approximation inverse function is applied correct systematic errors reduced sensor. Residual corrected output can be uncertainty calcu...

researchers of csiro land and water in griffith in australia have found a way to repeatedly reuse drainage water to grow crops. in the process the system will concentrate the salt in the water to a manageable level which can then be used or stored in an environmentally friendly manner. the process, known as sequential biological concentration, is based on a novel system for land, based treatmen...

All-optical compact plasma focusing and transportation of electron beams, in the passive mode a lens, is studied via real geometry particle-in-cell simulations for its suitability laser wakefield acceleration technique. The an beam by lens non-linear dynamic process, which strongly depends on space charge induced evacuation electrons vicinity propagating beam. Effects such energy spread, diverg...

In recent years, laser doping of selective emitters (LDSE) has demonstrated great promise for improving c-Si solar cell performance with the potential for low cost of adaptation. Absolute cell efficiency improvement of 1 – 2 % is seen with a process pioneered at the University of New South Wales which couples narrow-line LDSE processing with a self-aligning, light-induced plating (LIP) metalliz...
