The pressure injection pump PGP 30/40 is an pneumatic driven 2- component gearpump, suitable for the work under mining and civil engineering conditions. It consists of a powerfull 8kW pneumatic drive and two mining approved high capacity gearpumps. With its high constant flowrate of 40 l/min at a pressure up to 40 bar, it is the perfect pump for all injections works where you must be able to pumpe a lot material in a short time frame. Of course this pump can be uses with all common Polyurethan injection resins. With additional gearpumps, that can be purchased optional, it is also possible to use this pump with injection resins which need a mixing ratio od 2:1 or 4:1. For safety reasons this machine is equipped with overpressure valves at both pressure outlets, and a mining approved pressure switch. Application: The PERFORATOR PGP 30/40 is a powerfull gearpump for the injection of 2- component injection Materials, mainly used in the mining and civil engineering industry. It is meant for the use with common 2- component Polyurethan injection Materials with a mix ratio of 1:1. Due to the high flowrate generated by this pump it is predestined for all jobs where you have to pump much material in a short period of time.

Parkinson's disease (PD) is a common progressive neurodegenerative disorder. Studies using resting-state functional magnetic resonance imaging (fMRI) to investigate underlying pathophysiology of motor and non-motor symptoms in PD yielded largely inconsistent results. This quantitative neuroimaging meta-analysis aims to identify consistent abnormal intrinsic functional patterns in PD across studies. We used PubMed to retrieve suitable resting-state studies and stereotactic data were extracted from 28 individual between-group comparisons. Convergence across their findings was tested using the activation likelihood estimation (ALE) approach. We found convergent evidence for intrinsic functional disturbances in bilateral inferior parietal lobule (IPL) and the supramarginal gyrus in PD patients compared to healthy subjects. In follow-up task-based and task-independent functional connectivity (FC) analyses using two independent healthy subject data sets, we found that the regions showing convergent aberrations in PD formed an interconnected network mainly with the default mode network (DMN). Behavioral characterization of these regions using the BrainMap database suggested associated dysfunction of perception and executive processes. Taken together, our findings highlight the role of parietal cortex in the pathophysiology of PD.

In this work, we present a new method to analyze thick insulating samples by PIXE technique. The method is based on the use of both an electron flood gun to compensate the charge build-up at the insulating surface and a beam profile monitor (BPM) to provide a precise indirect measurement of the beam current and accumulated charge. A filament extracted from an ordinary flashlight lamp was used as an electron flood gun. While, a commercial BPM has been adapted in order to carry out charge measurements. The results have revealed the convenience of using BPM for measuring the charge in PIXE measurements. The use of the electron flood gun has given very satisfactory results in term of preventing charge build-up and reducing its contribution to the bremsstrahlung background in the PIXE spectra. The applicability and efficiency of the overall system for elemental analysis were successfully verified using IAEA-Soil-7 reference material where both accuracy and precision were found to be better than 10% in most cases.

► A new comprehensive method to analyze directly thick insulating samples by PIXE technique is presented. ► The method is based on the use of an electron flood gun and a beam profile monitor. ► Both accuracy and precision of the experimental procedure were successfully verified using reference material.
