Fusion of visual and infrared thermography images for advanced assessment in non-destructive testing.

For better evaluation of infrared measurements in non-destructive testing, especially for objects with complex geometry or small dimensions, it is beneficial to combine with the same viewing angle an image of a camera in the visible range with the image of an infrared camera. In the hybrid camera developed by us, a beam splitter is used which combines the visible and the infrared wavelength regions under the same viewing angle to form a hybrid image. The applications of this new technique range from the localization and the verification of false indications in non-destructive testing applications to the retrieval of 3D surface information with a hybrid picture as texture with defect indications and the filtering of laser markings displayed in the IR image to area and process monitoring.

Somatic kinetics or paroral membrane: which came first in ciliate evolution?

The ciliate species which lack a distinctive oral ciliature are considered to represent an ancestral state in ciliate evolution. Consequently, the somatic kineties composed of kinetids (kinetosomes plus cilia and associated fibrillar systems) are thought to be the ancestral ciliature. Results on stomatogenesis in 'gymnostomial ciliates' have shown that these ciliates probably have evolved from ancestors already equipped with an oral ciliature.

[Therapeutic local anesthesia in backache].

Low back pain for which operative therapy is not indicated, can prove resistant to treatment even with the aggressive application of conservative measures and the use of suitable drugs. Here, local anesthesia can often have a decisive influence on pain. On account of possible complications, particular consideration must be given to pharmacological aspects.

Electron microscopical observations on the ciliate Furgasonia blochmanni Fauré-Fremiet, 1967: Part II: Morphogenesis and phylogenetic conclusions.

The ultrastructural events during cortical morphogenesis of Furgasonia blochmanni are studied by TEM. The kinetosomal proliferation in the somatic cortex at the beginning of morphogenesis produces kinetosomal triads. All kinetosomes of these triads have the same fibrillar systems as somatic monokinetids.

Electron microscopical observations on the ciliate Furgasonia blochmanni Fauré-Fremiet, 1967: Part I: An update on morphology.

Light- and electron microscopical observations on the morphology of the nassulid ciliate Furgasonia blochmanni show that it has somatic kinetids which reveal the nassulid pattern of somatic mono- and dikinetids with a 'B-cartwheel' in the lumen of the kinetosome and paired alveolocysts as regular components of the kinetids. The buccal ciliature consists of a paroral membrane and three adorai membranelles. In contrast to the majority of the nassulid ciliates F.

[Significance of meningitis as a complication of spinal anesthesia].

A case is reported where the patient developed severe bacterial meningitis only hours after surgery. As a general anaesthetic was administered, no causal relationship could be found; spinal anaesthesia had originally been planned.

[Anesthesia for nuclear magnetic resonance tomography (NMR)].

The NMR-Tomography as a new imaging device is still in the experimental stage for clinical use. It has distinct advantages in comparison to other conventional methods especially when considering special indications and clinical considerations. In some cases NMR-Tomography can only be carried out when a patient is under general anesthesia.

[Problems in laser surgery and anesthesia].

Accidental thermal damage in case of explosion and fire caused by laser-surgery is a well-known problem and still not solved. A combination of laser beam, oxygen and inflammable substances are only one aspect. A main problem is the venturi-effect resulting from artificial ventilation under anaesthesia.

[Experiences with therapeutic whole-body hyperthermia].

Therapeutic whole body hyperthermia (WBH) as an additional therapy in the treatment of cancer has been known for a long time and is beginning to attain acceptance. In a clinical study 28 patients were treated 70 times with WBH at a core temperature of 41.8 degrees C.

The effect of whole body hyperthermia on 5-fluorouracil pharmacokinetics in vivo and clonogenicity of mammalian colon cancer cells.

In a non-randomized pilot study, 10 patients with histological proof of metastatic colorectal adenocarcinoma were treated by hyperthermia/chemotherapy protocol (41,8 degrees C and 1000 mg 5-FU). Plasma levels of 5-FU were determined after single dose at normothermia and hyperthermia. Plasma concentration time course was consistent with a two-compartment pharmacokinetic open model, with first order kinetic and was significantly altered by hyperthermic treatment.

[Extracorporeally induced whole-body hyperthermia in conventionally incurable malignant tumor patients].

Whole body hyperthermia was produced in 14 patients with conventionally incurable malignant disease. The technique consisted of arteriovenous shunting involving extracorporeal circulation with heat exchange during general anaesthesia. A temperature of 41.

[Changes of pressure within the middle ear during various kinds of anaesthesia (author's transl)].

Measurements of the middle ear pressure were taken during anaesthesia in 18 patients. Using nitrous oxide the middle ear pressure increased considerably. Other anaesthetics (i.

Synthesis and biological activity of seventeen analogues of human insulin.

We synthesized seventeen analogues of human insulin, applying the principle of stepwise, selective formation of the disulphide bonds. Most of these analogues only differ from human insulin in the replacement of a single amino acid in positions 2, 5, 6, 7, 8 and 11 of the A chain and 5, 7, 13 and 16 of the B-chain. The influence of these modifications on the physicochemical properties of the analogues is discussed.
