The effect of melt quality on hot tearing susceptibility of Al8Si3Cu alloy was examined under six different conditions, by using a traditional T-shaped mold. Grain refinement was carried out by two different modifiers: AlTi5B1 and Al3B. For each test, samples were cast before and after degassing of melt. Therefore, a new hot tearing tendency index was developed by both bifilm calculations and porosity that occurred in the middle of T-zone of casting parts. Results indicated that hot tearing of cast aluminum alloys was a complex phenomenon, and bifilms play a major role, especially by compensat ...Daha fazlası

Code Blue (CB) is an emergency that requires appropriate sequential actions gained through training with organized teamwork. This research has been conducted to evaluate the efficacy, efficiency, and application results of code blue which is used in our hospital
Pancreatic cancer is one of the most aggressive cancer due to the late diagnosis and failure to respond to the treatment despite advances in tumor biology and the development of new cancer therapeutic strategies. It has been reported that these characteristics of pancreatic cancer originate from cancer stem cells within the tumor mass. It has also been reported that Fentanyl is a fast-acting analgesic that binds to the mu-opioid receptors and some other mu-opioid receptors are involved in this cancer process. In this study, we determined the effect of Fentanyl on PANC-1 cells, by assessing the ...Daha fazlası
Charged-particle spectra at midrapidity are measured in Pb–Pb collisions at the centre-of-mass energy per nucleon–nucleon pair TeV and presented in centrality classes ranging from most central (0–5%) to most peripheral (95–100%) collisions.
Background: The 2019 novel coronavirus disease (COVID-19) pandemic has triggered a devastating effect worldwide. Objectives: This review of rehabilitation strategies and neurological consequences in patients with COVID-19 sought to consider potential neurorehabilitation strategies for managing the emerging neurological consequences of COVID-19. Methods: An exploratory review was conducted that comprised a narrative synthesis in two parts. Part I focused on neurological consequences and physiotherapy and rehabilitation approaches. Part II focused on general principles of rehabilitation interven ...Daha fazlası
Background: The 2019 novel coronavirus disease (COVID-19) pandemic has triggered a devastating effect worldwide. In addition to cardiovascular, pulmonary, and musculoskeletal deconditioning, reports of neurological consequences (e.g. stroke, critical illness polyneuropathy, myopathy, vertigo, headaches, facial palsy, and delirium) are growing increasingly common.

The measurement of the production of prompt D0, D+, D∗+, and D+s mesons in proton–lead (p–Pb) collisions at the centre-of-mass energy per nucleon pair of √sNN = 5.02 TeV, with an integrated luminosity of 292 ± 11 μb−1, are reported. Differential pro- duction cross sections are measured at mid-rapidity (−0.96 < ycms < 0.04) as a function of transverse momentum (pT) in the intervals 0 < pT < 36 GeV/c for D0, 1 < pT < 36 GeV/c for D+ and D∗+, and 2 < pT < 24GeV/c for D+s mesons. For each species, the nuclear modification factor RpPb is calculated as a function of pT using a proton-proton (pp) ref ...Daha fazlası
The pT-differential production cross section of prompt Λ+c charmed baryons was measured with the ALICE detector at the Large Hadron Collider (LHC) in pp collisions at √s = 7 TeV and in p-Pb collisions at √sNN = 5.02 TeV at midrapidity. The Λ+c and Λ–c were reconstructed in the hadronic decay modes Λ+c → pK−π+, Λ+c → pK0S and in the semileptonic channel Λ+c → e+νeΛ (and charge conjugates). The measured values of the Λ+c /D0 ratio, which is sensitive to the c-quark hadronisation mechanism, and in particular to the production of baryons, are presented and are larger than those measured previously ...Daha fazlası

In the present study, the corrosion behaviour of A356 (Al-7Si-0.3Mg) alloy in 3.5% NaCl solution has been evaluated using cyclic/potentiodynamic polarization tests. The alloy was provided in the unmodified form and it was then modified with AlTi5B1 for grain refinement and with AlSr15 for Si modifications. These modifications yield to better mechanical properties. Tensile tests were performed. In addition, bifilm index and SDAS values were calculated and microstructure of the samples was investigated. As a result of the corrosion test, the Ecorr values for all conditions were determined approx ...Daha fazlası

The effects of degassing, holding time and melt additions (Sr, Sr + Ti, Ti, B and B + Sr) on the quality of A356 melts were examined. A total of 120 reduced pressure test samples were collected. Pores in these samples were analyzed via digital image processing to determine the number density of pores as well as the statistical distribution of their sizes. Results showed that in all cases, degassing with argon reduced the number of defects regardless of the additions made to the melts. Moreover, all additions were found to degrade melt quality. The lowest number density of pores in all melts wa ...Daha fazlası
The production of J/ψ and ψ(2S) was studied with the ALICE detector in Pb-Pb collisions at the LHC. The measurement was performed at forward rapidity (2.5 < y < 4) down to zero transverse momentum (pt) in the dimuon decay channel. Inclusive J/ψ yields were extracted in different centrality classes and the centrality dependence of the average pt is presented. The J/ψ suppression, quantified with the nuclear modification factor (RAA), was measured as a function of centrality, transverse momentum and rapidity. Comparisons with similar measurements at lower collision energy and theoretical models ...Daha fazlası

The results were obtained in an extended transverse momentum interval, 2 < pT < 20 GeV/c, and with an improved precision compared to previous measurements performed in the same rapidity interval at centre-of-mass energies The pT- and y-differential production cross sections as well as the pT-differential production cross section ratios between dif ...Daha fazlası
