    Evaluation of the changes in mechanical properties of 3D printed parts resulting from variation of basic 3D printing parameters

    The advances in additive manufacturing techniques in recent years, especially the development of 3D printing techniques for polymer and metal 3D printing see rise of the use in these techniques in deferent fields of industry, like automotive, oil and gas and aero and space. Using these techniques for on demand manufacturing of spare parts used parallel to existing manufacturing techniques introduces the need for good evaluation of the mechanical properties of the 3D printed part. This paper evaluates the changes in the mechanical properties of standard parts used for ISO standards evaluation of parts made with polymeric materials. To this end we 3D print standard part with different basic 3D printing properties like, layer height, line width, infill density, number of perimeters and infill orientation. These parts are tested using the ISO standard for tensile measurements of plastic parts analyzing the elastic modulus, maximum force at break, the creep of the material. From acquired data we evaluate the optimal 3D printing properties needed to establish the best mechanical parameters of the 3D printed part.

    Nitric oxide is a ubiquitous molecule involved in a range of physiologic and pathophysiologic processes, and is often at the centre of the scientific debate with its inherent complexity. Synthesised under the influence of its three isoenzymes, this molecule has been implicated in processes like inflammation, premature birth and carcinogenesis. Via comparative and experimental biochemical analysis of the cervical fluid of a group of patients with premature labour pains, using the indirect method of detection (the Griess spectrophotometric analysis), as well as analysis of the systemic inflammatory response, this study shows the association of nitric oxide with the premature births before the gestational week 34 as an independent marker for development of premature birth. It also showsthe association between the local nitric oxide synthesis in the vagina and the systemic inflammatory response and the significance of this association in the development of premature birth
