In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys electroless plating. The properties of metal layers on were characterized SEM, resistance tester and metallographic microscope, respectively. When laser energy density is relatively low (Q<60J·cm -2 ), there mainly photothermal effect surface substrate presents ...

We study the implication of the time-dependent CP asymmetry in B → π + π − decays on the extraction of weak phases taking into account the precise measurement of sin 2β, obtained from the " gold-plated " mode B → J/ψKS. Predictions and uncertainties for the hadronic parameters are investigated in QCD factorization. Furthermore, independent theoretical and experimental tests of the factorization...

Direct contingency analysis has been shown to be important. Instead of this success providing a powerful foundation for major advances in all of the important areas of psychology, I fear that it is becoming a gold plated cage. My evidence: relatively narrow areas of interest are dominating the field, both applied and basic. We are not expanding, and a field not busy being born is a field that i...

Background: The aim of the study was to analyse compare between interlock nailing and dynamic compression plating in humerus diaphyseal fractures its functional surgical outcome. Methods: 2019 2022, patients were randomly divided into two groups with help computer-generated coded envelopes, group A (humerus treated plating) B nailing) 20 each group. Outcomes evaluated based on operative time, b...

near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. these pulse-type ground motions can be represented by pulse sequences with simple shapes. half-sinusoidal pulse sequences are used to approximate recorded ground motions and dynamic responses of sdof system under the excitation of these pulse sequences are studied. four cases are consi...

To improve the electromagnetic characteristics of conductive nano fillers, carbon nanofibers (CNFs) with nickel-phosphorous (Ni-P) and nickeliron (Ni-Fe) have been fabricated by the electroless plating process. Observations by the electron microscopy (SEM/TEM) and element analyzer (EDS/ELLS) showed the uniform Ni-P and Ni-Fe coated CNFs. The compositions of the plating layers were about Ni-6wt%...
