In this paper, a unique healthcare solution is described that supports the even more effective operation of the hospital information systems. The main question is whether the emerging opportunities of the Internet of things devices can also be exploited in the industrial hospital information system landscape. This demonstrated research describes the most feasible way to integrate the Internet of things capability into hospital information production systems. The initial goal was the design and implementation of a single, unified telemedicine hub offering community-based solution for integrated medical systems. This solution allows the intercepted information to be collected and interpreted at community level. The designed and implemented system acts as a transmitter between the physician and patient. The software solution operates with sensor-based information collected from the individual. Emerging Internet of things devices and solutions open new horizons for today’s health care systems. The presented and detailed system provides the ability to real-time health-monitoring and in-depth health analyzing through open application programming interfaces. The telemedicine hub system makes it easier to integrate the Internet of things capability into the operating health care systems.

This paper presents a new method based on thin-layer chromatographic separation, and image analysis (TLC-IA) of saffron colorant compounds for the discrimination of saffron from different origins. The color compounds of dried and ground saffron stigmas are extracted and separated by thin-layer chromatography at optimum conditions. After chromatographic development, the chromatograms are photographed, and intensity profiles of RGB characteristics are produced and processed by specially designed image analysis software. The main factors such as the extraction procedure of color compounds, chromatographic system (stationary and mobile phase), and designing of image analysis software are described. This method includes a new and fast data acquisition and does not require expensive instruments. The method also allows for comparison of different types of saffron using RF values, color range, and intensity of the separated color components. This method is successfully applied to determine the saffron from different regions of Iran and various adulteration colorants.

Correlated measurement of the lifetime and of the lineshape of the 511 keV annihilation radiation of positrons (age-momentum correlation, AMOC) has become a powerful tool for investigating reactions of positron or positronium in condensed matter as a function of time. The beam-based+
AMOC method installed at the Stuttgart relativistic positron beam facility (Ekine+
4MeV) offers substantial advantages over the conventional
E coincidence technique resulting in a fast data taking due to the unity detection efficiency of the+ scintillator which provides the start signal for the lifetime measurement. In this paper the application of AMOC to positronium chemistry is illustrated by the study of spin conversion of positronium in the system methanol/HTEMPO as a function of HTEMPO (4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl, a paramagnetic solute) concentration. The same technique can be applied to other systems and other reactions in positronium chemistry, e. g., oxidation or complex formation.
Thermal neutron prompt gamma activation analysis (PGNAA) has proven to be a useful tool for the multi-elemental characterization
of coal. The use of isotopic neutron sources allows the construction of relatively small irradiation facilities for the on-line
analysis of large volume samples. As a first step to an on-line analysis system for process control in a coal blending plant
we have developed a facility using a Cf-252 neutron source with an actual strength of 1 mg. This source, which is shielded
by layers of high purity lead and paraffin, can be moved to the center of cylindrical sample holders containing up to 150
kg of coal. To avoid background radiation the sample holders are made from polyethylene. The prompt gamma rays emitted from
the sample are measured with a 22% high purity germanium detector housed in a special horizontally extended cryostate assembly.
The detector is positioned on top of the sample; it is surrounded by a multi-layer decreasing Z-absorber to reduce low energy
gamma background. Paraffin loaded with 95% enriched lithium-6-carbonate is used between sample and detector as a gamma window
with high absorption for thermal neutrons. Moreover the detector is shielded against background radiation by lead and natural
lithiumcarbonate. The data processing system consists of high count-rate analogue electronics including pileup-suppression
and a fast data acquisition system, which permits on-line analysis of the collected data. Analysis of several samples of simulated
coals as well as Western Germany coals shows a good spectral response of our system for the elements H, C, Al, Si, S, Cl,
Ca, Ti and Fe, whereas the sensitivity for N, K and Na is somewhat lower. This means, that the quantitative determination
of the above elements will be possible within 20 minutes. Optimization of the system is continued with a stress on analysis
time and detection sensitivity.
seconds, which meant the cold water trap/desiccant removed the water vapor rapidly and the analyzer was optimized for fastdata acquisition without sacrificing accuracy. Laser smoke signal was next in least errors hierarchy in that it had a similar
