An Assessment on Average Pressure Drop and Dust-Holding Capacity of Hollow-Fiber Membranes in Air Filtration.

In this work, we tried to analyze dust loading behavior of polypropylene hollow fiber membranes using average pressure drop models. Hollow fiber membranes varying in fiber diameter were loaded with a standardized test dust to simulate particle-polluted air. We measured pressure drop development of the membranes at different flowrates and dust concentrations, and, after each experiment, the dust deposited on the membrane fibers was weighed to obtain dust holding capacity (DHC).

[Distant healing and diabetes mellitus. A pilot study].

Background: The Institut für Grenzgebiete der Psychologie und Psychohygiene, Freiburg (IGPP) in cooperation with the Abteilung Naturheilkunde, University Hospital, Zürich investigated whether Distant Healing has a beneficial effect on patients with diabetes mellitus regarding the state of the disease and quality of life.

Objective: The goal of the pilot study was to observe the progression of the disease with various medical and psychological measures and to explore which of them might be sensitive for measuring possible treatment effects.

Patients And Methods: 14 diabetic patients were observed for a period of 16 weeks.

Analgesic efficacy of the serial application of a sulfurated mud bath at home.

The purpose of this randomized controlled trial was to evaluate the analgesic efficacy of a series of applications of sulfurated mud baths in outpatients suffering from back pain. Within 2 weeks 13 patients took 6 sulfurated mud baths (group A) and 12 patients 6 tap water baths (group B) at home. Before the bath and over 48 h after starting the 1st and the 6th bath, pain intensity was evaluated by the patients according to a visual analogue scale (VAS).
