UNLABELLED Lasers have been used in the management of benign prostatic hyperplasia for the last two decades. To be comparable, they should reduce or avoid the immediate and long-term complications of transurethral resection of the prostate (TURP) or open prostatectomy (OP), especially bleeding and need for blood transfusion. Although Holmium laser treatment of the prostate was compared frequent...

Failure and fault slip in crystalline rocks is associated with dilation. When pore fluids are present drainage insufficient, dilation leads to pressure drops, which turn lead strengthening of the material. We conducted laboratory rock fracture experiments direct in-situ fluid measurements demonstrate that dynamic rupture propagation can be stabilised (i.e., become quasi-static) by such a dilata...

PURPOSE There is a paucity of information on the clinical efficacy and safety of the photoselective vaporization (PVP) of the prostate using the 180W lithium triborate (LBO) laser. We report on initial outcomes of PVP with the 180W laser, comparing the first 50 cases with the last 50 cases performed with the 120W LBO laser. METHODS All cases performed by a single surgeon (HHW) have been prosp...

Modern spark ignition engines mostly use one injection system to deliver gasoline into the combustion chamber, using either direct or port fuel injection. Both technologies have their respective advantages. To integrate advantages and promote of renewable fuels, dual are in development recent years. Dual represents an advanced is a novel technology address urgent issues sustainability environme...

OBJECTIVES To compare the safety and efficacy of bipolar transurethral plasma vaporisation (B-TUVP) as an alternative to the 'gold standard' monopolar transurethral resection of the prostate (M-TURP) for the treatment of benign prostatic hyperplasia (BPH) in a prospective randomised controlled study. PATIENTS AND METHODS In all, 82 patients indicated for prostatectomy were assigned to two gro...

In the framework of Work Package DIV 1 – “Divertor Cassette Design and Integration” EUROfusion action, a research campaign has been jointly carried out by University Palermo ENEA to investigate steady-state thermal-hydraulic performances DEMO divertor cassette cooling system. The activity focussed onto most recent design Body (CB) circuit, consistent with baseline 2017 equipped liner two Reflec...

Unconstrained metal powders of Cu, Cr, Ni and Al were applied to submerged arc welding (SAW) clarify the chemical behaviour copper in this modified SAW process. Aluminium is avoided because it easily oxidised. Excessive aluminium oxides form slag or inclusions weld will lead poor materials properties. an effective deoxidiser can be used prevent Cr loss by preventing oxidation these metals. The ...

Space weathering is now commonly accepted to modify the optical and magnetic properties of airless body regoliths throughout the Solar System. Although the precise formation processes are not well understood, the presence of ubiquitous sub-microscopic metallic iron (SMFe) grains in lunar soils and corresponding spectral analyses have explained both the unique optical and magnetic properties of ...
