Development of a CT Image Analysis Model for Cast Iron Products Based on Artificial Intelligence Methods.

This paper presents an assessment of the possibility of using digital image classifiers for tomographic images concerning ductile iron castings. The results of this work can help the development of an efficient system suggestion allowing for decision making regarding the qualitative assessment of the casting process parameters. Special attention should be focused on the fact that automatic classification in the case of ductile iron castings is difficult to perform.

Technological Optimization of the Stirrup Casting Process with the Use of Computer Simulations.

In the initial stage, the output technology was analyzed, and on the basis of a series of virtual experiments the cause of defects in the casting was highlighted. The optimization process includes different designs of a gating system.

Intrathoracic negative pressure therapy and/or endobronchial valve for pleural empyema minimal invasive management: case series of thirteen patients and review of the literature.

Introduction: Intrathoracic negative pressure therapy is an adjunct to standard methods of complex empyema management in debilitated patients. Nevertheless, the use of endoscopic one-way endobronchial valves to successfully close large bronchopleural fistulas in patients with advanced pleural empyema has been described in only a few case reports.

Aim: To present our experience in managing complex pleural empyema using thoracostomy with intrathoracic negative pressure therapy and/or endobronchial valve implantation.

Social mobility of the father influences child growth: A three-generation study.

Model identification of stomatognathic muscle system activity during mastication.

The present study aimed to determine the numeric projection of the function of the mandible and muscle system during mastication. An experimental study was conducted on a healthy 47 year-old subject. On clinical examination no functional disorders were observed.

Patient-Specific CT-Based Instrumentation versus Conventional Instrumentation in Total Knee Arthroplasty: A Prospective Randomized Controlled Study on Clinical Outcomes and In-Hospital Data.

Total knee arthroplasty (TKA) is a frequently performed procedure in orthopaedic surgery. Recently, patient-specific instrumentation was introduced to facilitate correct positioning of implants. The aim of this study was to compare the early clinical results of TKA performed with patient-specific CT-based instrumentation and conventional technique.

Identification and association of relationships between selected personal and environmental factors and formal components of temperament and strategies of coping with stress in asthmatic patients.

Background: Personal and environmental factors might have an impact on strategies of coping with stress and temperamental traits according to the Regulative Theory of Temperament in asthmatic patients. They can modify the clinical picture, the course of a disease and effectiveness of treatment. Personal variables are key factors in determining formal characteristic of behavior and effective management method in asthmatic patients.

Blood vessel matrix seeded with cells: a better alternative for abdominal wall reconstruction-a long-term study.

Purpose: The aim of this study was to present abdominal wall reconstruction using a porcine vascular graft seeded with MSC (mesenchymal stem cells) on rat model.

Material And Methods: Abdominal wall defect was prepared in 21 Wistar rats. Acellular porcine-vascular grafts taken from aorta and prepared with Triton X were used.

Pretreatment verification of dose calculation and delivery by means of measurements with PLEXITOM™ phantom.

Aim: To validate a pretreatment verification method of dose calculation and dose delivery based on measurements with Metaplex PTW phantom.

Background: The dose-response relationships for local tumor control and radiosensitive tissue complications are strong. It is widely accepted that an accuracy of dose delivery of about 3.

Socio-demographic characteristics of patients with diagnosed functional dyspepsia.

Introduction: The term "dyspepsia" comes from the Greek words "dys' and 'peptin", which maen "ill digestion" or indigestion, although this set of symptoms in the adult clinic has little to do with the digestion or absorption process, and refers more to ailments related to the upper section of the gastrointestinal tract.

Aim: Assessment of the frequency of functional dyspepsia diagnosis, the characteristics of the group and an attempt to identify the accompanying symptoms, assessment of histological lesions and an attempt to answer question about the efficiency of anti-secretory and eradication therapy.

Material And Methods: The study involved patients reporting for gastrofiberscopic examination due to dyspeptic ailments.

Biomarkers in management of inflammatory bowel disease.

In recent years the use of faecal and serologic biomarkers has been evaluated in the diagnosis and management of inflammatory bowel disease (IBD). Faecal calprotectin (FC) has been proposed as a surrogate marker for intestinal inflammation; elevated concentrations in IBD patients have been confirmed in numerous studies. Already available rapid calprotectin tests help to differentiate between IBD and irritable bowel syndrome.

Spontaneous rupture of the spleen - a rare case.

The study presented two cases of spontaneous rupture of the spleen. Both patients were treated at the Department of General, Oncological, and Endocrinological Surgery. The first patient underwent splenectomy.

Anodic oxidation of oxidized forms of coenzymes Q(10) and Q(0) on carbon electrodes in acetic acid solutions.

The anodic oxidation of oxidized forms of coenzyme Q(10) (ubiquinone, CoQ(10)) and Q(0) (CoQ(0)) on a glassy carbon macroelectrode (GC) and on a carbon fiber microelectrode (CF) was investigated in acetic acid using voltammetric techniques. Voltammograms recorded on these electrodes show well-defined peaks or waves in the potential range of above 1.5 V (vs.

Education concerning carcinoma of prostate and its early detection.

Introduction And Objectives: Prostate cancer is the most common male cancer. Insufficient knowledge of PCa among men causes its low detection. Lack of essential actions in health education and widely understood prophylaxis, the need of the latter are maybe responsible for the increasing mortality rate.

Chromatographic methods and techniques used in studies of coals, their progenitors and coal-derived materials.

The use of chromatography in studies of coals, their progenitors and coal-related products was reviewed. The specificity of the coal structure was discussed. The use of extraction in preparing study samples was discussed paying special attention to the occurrence of undesirable phenomena such as aggregation of coal derivate molecules, resulting from the formation of their dimers and trimers, and degradation of polar solvents at temperatures above 350 °C.

A mechanistic interpretation of root transport of water.

The present paper offers a mechanistic interpretation of filtration coefficients L(pr) in isolated maize roots, measured with the use of the root pressure probe by Steudle and others (Steudle 1990, 1992; Steudle and Brickmann 1989; Steudle and Frensch 1989; Steudle and Jeschke 1983; Steudle et al. 1993) on the basis of the Kedem-Katchalsky equations.
