Gd-149:What's confirmed? What's new?

A long run performed with EUROGAM II allowed remeasuring the Gd-149 superdeformed (SD) band 1. The Delta I = 4 bifurcation in band 1 is confirmed and two resolved gamma-ray transitions linking the SD band 1 and the normal deformed states have been observed

The Effectiveness of Mindfulness Training- Cognitive Bias Modification in Reducing Anxiety Symptoms

Background and Purpose: Early conceptualizations of anxiety indicate that maladaptive cognitions cause and maintain anxiety disorders so that anxious people show bias in processing information, prefer to pay attention to threatening stimuli, and interpret emotional ambiguity in a threatening direction. Therefore, the present study aimed to examine the effectiveness of mindfulness training-attention bias modification in reducing anxiety symptoms. Methods: The current research method was quasi-experimental with a pretest-posttest design, and a control group. The statistical population consisted of experimental and control groups of students at the University of Kurdistan; hence, 31 students were selected by convenience sampling through recall and randomly assigned to experimental and control groups. Before and after the intervention, the participants responded to the Beck Anxiety Inventory (BAI) and the Spielberger state-trait anxiety inventory, as well as the dot-probe test. Results: The analysis of results using the repeated measures univariate analysis of variance (ANOVA) indicated a significant effect of the intervention and showed that the combined treatment of cognitive bias modification with mindfulness training reduced anxiety scores (beck, state, trait), and also reduced attention bias towards the threat. Conclusion: The results indicated that mindfulness- attention bias modification in the present study had the necessary efficiency to reduce social anxiety; hence, the therapy was effective

Synthesis, Electrochemical, Thermodynamic, and Quantum Chemical Investigations of Amino Cadalene as a Corrosion Inhibitor for Stainless Steel Type 321 in Sulfuric Acid 1M

The corrosion of stainless steel is one of the major industries’ issues that gained wide interest among researchers. It became necessary to develop and apply eco-friendly approaches to corrosion control. This work explores the inhibitory effect of a newly synthesized amino cadalene (ACM) on the corrosion of stainless steel type 321 in sulfuric acid 1M. Particularly, the experimental study consisting of electrochemical and surface analyses was conducted in conjunction with a theoretical approach. The electrochemical results showed that ACM acted as a mixed-type corrosion inhibitor and the inhibition efficiency attained 91% at 10−3M. EIS measurements revealed that both metal charge transfer and diffusion processes are involved in the interfacial metal/solution reactions. The interfacial mechanism is thoroughly investigated; the physisorption of the protonated molecules was preceded by the formation of a negative layer due to adsorption of the solution anionic species. The experimental insights are corroborated with the quantum chemical calculations

Fabrication of TiO2 Nanotube by Electrochemical Anodization: Toward Photocatalytic Application

In this study, a self-organized nanotubular titanium dioxide (TiO2) array was successfully produced by anodizing pure titanium in a mixture of glycerol, distilled water (8% vol.), and ammonium fluoride using a dual electrode system. The size control and distribution of the nanopores were performed in a DC voltage range varying from 30 V to 60 V. The diameter of TiO2 nanopores varies from 59 to 128 nm depending on the anodizing voltage. Energy-dispersive X-ray spectroscopy (EDX) analysis reveals that the as-prepared films are essentially composed of TiO2. According to the X-ray diffraction (XRD) and Raman spectroscopy analysis, the nanotubular arrays of TiO2 annealed at 600°C for 2 hours are composed of a phase mixture of anatase and rutile. Mott-Schottky analysis showed that the TiO2 nanotubes are consistent with an n-type semiconductor with a donor density of about 1017 cm-3. Preliminary results on the photocatalytic degradation of a pharmaceutical pollutant showed that the TiO2 nanotubes can be used as a promising material for application in wastewater treatment
