Abstract:
This study investigated the neuroprotective effects of Dendropanax morbifera leaves and stems (DMLS) water extract on scopolamine (SCO)-induced memory impairment in mice. First, we conducted experiments to determine the protective effect of DMLS on neuronal cells. Treatment with DMLS showed a significant protective effect against neurotoxicity induced by Aβ(25–35) or H2O2. After confirming the neuroprotective effects of DMLS, we conducted animal studies. We administered DMLS orally at concentrations of 125, 250, and 375 mg/kg for 3 weeks. In the Y-maze test, SCO decreased spontaneous alternati

Abstract:
Background. Direct metal laser sintering (DMLS) is an additive manufacturing technique that allows the fabrication of dental implants layer by layer through the laser fusion of titanium microparticles. The surface of DMLS implants is characterized by a high open porosity with interconnected pores of different sizes; therefore, it has the potential to enhance and accelerate bone healing. To date, however, there are no histologic/histomorphometric studies in the literature evaluating the interface between bone and DMLS implants in the long-term. Purpose.

Introduction: A close marginal adaptation of a fixed partial denture is crucial for its long-term functionality without any adversity. Human errors and casting defects are common with conventional techniques. The latest techniques, direct metal laser sintering (DMLS), and computer-aided design and manufacturing (CAD/CAM) tend to overcome these errors. Methods: 33 dies were fabricated from similar number of impressions of a tooth based on standardized measurement and were equally distributed in 3 groups (11 each).

Abstract:
Injection molding is one of the most common methods of mass production. After injecting molten plastic into a mold, the heat must leave the plastic material, enter the mold steel, enter the coolant, and exit the mold. This heat flow is critical to producing high quality parts rapidly. As plastic cools, the plastic shrinks. Uneven cooling causes uneven shrinkage which can cause the part to warp from the resulting internal stresses or create sink marks on the part. Thus the effect of uneven cooling is lower part quality, both in appearance and in dimension. Standard or conventional cooling chann

However, DMLS generally produces material with lower mechanical performance and higher anisotropy as compared to conventional manufacturing approaches of the same material. Furthermore, components made by DMLS are believed to be more vulnerable to corrosion due to the presence of residual porosity, as well as laser induced microstructural deformations.

Abstract:
Recent technological advances in the field of additive manufacturing (AM), particularly with direct metal laser sintering (DMLS), have increased the potential for building gas turbine components with AM. Using DMLS for turbine components broadens the design space and allows for increasingly small and complex geometries to be fabricated with little increase in time or cost. Challenges arise when attempting to evaluate the advantages of DMLS for specific applications, particularly because of how little is known regarding the effects of surface roughness. This paper presents pressure drop and hea

Abstract:
We show that clock synchronized transmission has reduced receiver-side jitter that limits DMLs’ performance compared to conventional clock and data recovery. We access transmission quality using 35-GHz-bandwidth DMLs at 1271 and 1373 nm.

Abstract:
Additive manufacturing (AM) via the direct metal laser sintering (DMLS) route is a new technology for both new make and repair application in gas turbine hot gas path components. This paper presents the development of a new oxidation coating Ceral 10 as a protective coating on the AM CoCrMo alloys. A high Al activity slurry aluminide coating (Ceral 10) was deposited on the DMLS CoCrMo. The coating produced on DMLS CoCrMo was uniform and intact having a thickness of ∼ 80–100 μm. The slurry aluminide coating showed an Inward diffusion with the DMLS CoCrMo substrate having an Al of 38–40 wt% and

Abstract:
With the advances of Direct Metal Laser Sintering (DMLS), also generically referred to as additive manufacturing, novel geometric features of internal channels for gas turbine cooling can be achieved beyond those features using traditional manufacturing techniques. There are many variables, however, in the DMLS process that affect the final quality of the part. Of most interest to gas turbine heat transfer designers are the roughness levels and tolerance levels that can be held for the internal channels. This study investigates the effect of DMLS build direction and channel shape on the pressu

Abstract:
This essay presents a critical examination of trust in the context of minipublics (DMPs), with the aim of substantiating the notion of contingent trust and making recommendations for its formalization. Filling a gap in the literature on minipublics, it argues that proponents of DMPs have underestimated the conditions for public trust, risking a potential backlash against democratic innovations. It posits that trust in DMPs should not be based solely on their perceived benefits for democracy, but rather on the demonstrated trustworthiness of these mechanisms. And the trustworthiness of DMPs sho
