Optimisation of Strength Properties of FDM Printed Parts-A Critical Review.

Additive Manufacturing is currently growing fast, especially fused deposition modeling (FDM), also known as fused filament fabrication (FFF). When manufacturing parts use FDM, there are two key parameters-strength of the part and dimensional accuracy-that need to be considered. Although FDM is a popular technology for fabricating prototypes with complex geometry and other part product with reduced cycle time, it is also limited by several drawbacks including inadequate mechanical properties and reduced dimensional accuracy.

[Assessment of oncologic risk of breast reconstruction simultaneous with surgery for breast cancer].

The report deals with retrospective research in possible induction of relapse by breast reconstruction carried out simultaneously with surgery for breast cancer. The end results were compared between cases of modification of radical mastectomy combined with reconstruction (n=124) and controls who underwent surgery for cancer alone (n=379). Standard radio- and systemic therapy was used.

The use of TLD-700H dosemeters in the assessment of external doses at the former Semipalatinsk nuclear test site.

The joint projects performed since 1995 by the Jülich Research Centre in co-operation with the Kazakh National Nuclear Centre in the area of the former nuclear test site near Semipalatinsk, in eastern Kazakhstan, have assessed the current dose rate of the population at and around the test site, as well as determining retrospectively the dose rate of persons affected by the atmospheric tests. Measurements of the population by personal dosemeters depend on reliably wearing these dosemeters over prolonged periods of time, and of a sufficient dosemeter return. In the past, such measurements have been particularly successful whenever short wearing times were possible.

Cytogenetic biomonitoring carried out in a village (Dolon) adjacent to the Semipalatinsk nuclear weapon test site.

The Semipalatinsk region (Kazakhstan Republic) has been affected by extensive radioactive contamination due to more than 450 nuclear tests of which almost 100 were exploded in the atmosphere. The present results refer to cytogenetic assessments in a study cohort of the population of Dolon, a settlement located on the NE boundary of the nuclear weapon test site, which was exposed to elevated doses of ionising radiation primarily due to the first Soviet nuclear test in 1949. Conventional cytogenetic analyses were carried out on 21 blood samples from individuals (more than 50 years old) living in Dolon since the very beginning of nuclear testing.

[The effectiveness of breast-conserving surgery in T1-2N0M0 breast cancer].

A retrospective analysis of the end results of surgical treatment of 1.417 patients with T1-2N0-1M0 breast tumors is presented: local recurrence after radical surgery (1.151)-2.
