Optimization of Process Parameters for Steel Wire-Reinforced Polylactic Acid Composites Produced by Additive Manufacturing.

The mechanical performance of Fused Deposition Modeling (FDM)-produced polymer composites is highly dependent on processing parameters; however, most studies focus on unreinforced polymers, leaving a gap in understanding how these parameters influence continuous wire-reinforced composites. This study addresses this gap by investigating the effect of hatch spacing and layer thickness on the tensile properties of steel wire-reinforced PLA composites. The Taguchi method was employed to systematically optimize mechanical performance, using an L9 orthogonal array to evaluate tensile strength across different process conditions.

Effect of Atmospheric Plasma Treatment on Mechanical Properties of 3D-Printed Continuous Aramid Fiber/PLA Composites.

In this study, an aluminum heating block with two inlets (for the Polylactic acid (PLA) filament and the continuous aramid fiber) was produced and placed onto an extruder, and continuous-aramid-fiber-reinforced PLA composites were fabricated by using the nozzle impregnation method. Layer height values of 0.4 mm, 0.

Effect of morality or capitalist ideology in choosing dentistry as a career in Türkiye: a cross sectional study.

Background: Previous studies have provided important findings on the profession of dentistry and the motivators for choosing dentistry. This study has attempted to contribute to this accumulation by using a sociocultural perspective and interpreting the relationships among motivators from this perspective in a large Turkish sample. The aim of this study was to investigate what motivates dental students to choose dentistry as a career in Türkiye.

Vaccination status of COVID-19 patients followed up in the ICU in a country with heterologous vaccination policy: A multicenter national study in Turkey.

Objective: Vaccination against severe acute respiratory syndrome coronavirus-2 (SARS-2) prevents the development of serious diseases has been shown in many studies. However, the effect of vaccination on outcomes in COVID-19 patients requiring intensive care is not clear.

Methods: This is a retrospective multicenter study conducted in 17 intensive care unit (ICU) in Turkey between January 1, 2021, and December 31, 2021.

Effects of SARS-CoV-2 infections in patients with cancer on mortality, ICU admission and incidence: a systematic review with meta-analysis involving 709,908 participants and 31,732 cancer patients.

Background: Cancer patients constitute one of the highest-risk patient groups during the COVID-19 pandemic. In this study, it was aimed to perform a systematic review and meta-analysis to determine both the incidence and ICU (Intensive Care Unit) admission rates and mortality in SARS-CoV-2 infected cancer patients.

Methods: The PRISMA guidelines were closely followed during the design, analysis, and reporting of this systematic review and meta-analysis.

The Coherence Between Epistemologies and SSI Teaching: A Multiple-Case Study with Three Science Teachers.

Unlabelled: The purpose of the present study was to understand the nature of the link between science teachers' epistemologies and their socioscientific issue (SSI) teaching discourse. It is important to consider this link due to the limitations of science teachers in shifting from monologic to more dialogic orientations in their teaching, despite SSI-based science education reforms in many countries. Teachers' epistemologies are likely to contribute to the difficulties experienced in this shift.

Effect of radiation on brain tissue endothelin-1 level and tumor development.

Background: Radiotherapy causes injury in the endothelial cells of blood vessels and the production of vasoactive amines such as endothelin-1 (ET-1). ET-1 is an important peptide in cancer development. In this study, the effects of radiation on brain tissue ET-1 level were evaluated.

Clinical and radiological outcomes are correlated with the age of the child in single-stage surgical treatment of developmental dysplasia of the hip.

The principles of treatment of developmental dislocation of the hip (DDH) in an older child are different from those in a newborn. In the older child retraction of the muscles around the hip, associated with a marked acetabular dysplasia and elongation of the joint capsule explain the difficulty and instability of reduction and the frequency of complications. The aim of this study is to evaluate the effect of age on the results of a one-stage open reduction in developmental dislocation of the hip.

Presence of a meningioma in a cervical myelomeningocele sac.

An 11-year-old female, presented with a cervical myelomeningocele. Interestingly, the myelomeningocele sac was seen to contain a meningioma. There are no aetiological factors in the embryogenetic period that would lead to such a combination of lesions.

Cutting edge: the toll pathway is required for resistance to gram-positive bacterial infections in Drosophila.

In Drosophila, the response against various microorganisms involves different recognition and signaling pathways, as well as distinct antimicrobial effectors. On the one hand, the immune deficiency pathway regulates the expression of antimicrobial peptides that are active against Gram-negative bacteria. On the other hand, the Toll pathway is involved in the defense against filamentous fungi and controls the expression of antifungal peptide genes.
