ABSTRACT
The paper presents the results of an experimental study of a cylindrical orifice with the orifice diameter ratio ß = 0.5 and the flow opening length-to-diameter ratio L/d = 1, with hydraulic oil flowing in the DN50 measuring channel. The measurements of the values characterising the oil flow were made in the laminar flow regime, for the Reynolds numbers ranging between Re = 100 to 950. Based on the experimental tests, standard flow characteristics were created for four kinematic viscosity values in the range of 13.4-33.3 cSt, for which the average value of the discharge coefficient C in the tested flow rate range of qv < 0.5 dm3/s was determined.
ABSTRACT
The article presents the influence of the camera and its optical system on the uncertainty of object position measurement in vision systems. The aim of the article is to present the methodology for estimating the combined standard uncertainty of measuring the object position with a vision camera treated as a measuring device. The identification of factors affecting the location measurement uncertainty and the determination of their share in the combined standard uncertainty will allow determining the parameters of the camera operation, so that the expanded uncertainty is as small as possible in the given measurement conditions. The analysis of the uncertainty estimation presented in the article was performed with the assumption that there is no influence of any external factors (e.g., temperature, humidity, or vibrations).
ABSTRACT
Contraceptive is an important issue of women's life. In the present times there are many methods to prevent unwanted pregnancy. Each of them has its advantages and disadvantages and an appropriate choice of the method determines its promotion high efficiency and comfort its application. Today there is no method of contraception, which would not be charged some risk for the application. Following the review will allow literature to analyze impact of the various methods for the development of cancer control means diseases which may constitute a serious threat to health and life women.

INTRODUCTION: Discussion on the frequency of coexistent celiac disease and type 1 diabetes mellitus (DM1) as well as an attempt to standardize diagnostic methods of celiac disease detection among DM1 children have been performed. OBJECTIVES: To assess the incidence of celiac disease among DM1 children in the Pomeranian region of Poland followed by analysis of the putative prognostic factors for celiac disease development in this particular group of children. MATERIALS AND METHODS: 70 children aged 9.47+/-4.59 (group 1) de novo diagnosed with DM1 and 223 children aged 10.20+/-3.87 with long-standing diabetes mellitus type 1 (4.47+/-3.16 years from the diagnosis) were enrolled in the study. All the patients had C-peptide, HbA1c, CRP, TSH, fT4, fT3, urinary albumin secretion rate, IgA, level of antigliadin antibodies (AGA), anti-tissue transglutaminase (TGA) IgA and IgG antibodies (ELISA), anti-endomysium (EmA) IgA and IgG antibodies (immunofluorescence) and anti-tyreoglobulin antibodies (TG), anti-thyroid peroxidase (TPO) antibodies (ELISA) evaluated. All the patients had jejunal biopsy and thyroid ultrasound examination. RESULTS: 5.7% of group 1 patients were diagnosed with celiac disease based on the positive jejunal biopsy in comparison with 9.4% in the group 2. TGA antibodies were present in 9.52% of group 2, AGA in 7.62%, EmA in 6.19%. 10% of group 1 children had autoimmune thyroiditis versus 24.2% of group 2 children. The group of children with coincident long-lasting DM1 and celiac disease (group A) was characterized by significantly earlier age at diagnosis (p=0.003), higher HbA(1)c (p=<0.001), CRP (p<0.001) and elevated urine albumin secretion in relation to children without celiac disease and autoimmune thyroiditis (group B). Serologic test detecting TGA antibodies was found to be the most sensitive (95.2%) for the detection of celiac disease among DM1 children, while the lowest sensitivity was obtained in the case of the EmA antibody test (61.9%). CONCLUSIONS: The celiac disease morbidity confirmed by jejunal biopsy is high among DM1 children (9.4%). The assessment of the serum TGA appears to be the most sensitive screening marker for the celiac disease detection in DM1 children.
