Electronic instabilities at the crossing of the Fermi energy with a Van Hove singularity1 in the density of states often lead to new phases of matter such as superconductivity2,3, magnetism4 or density waves5. However, in most materials this condition is difficult to control. In the case of single-layer graphene, the singularity is too far from the Fermi energy6 and hence difficult to reach wit...

The purpose of this study was to determine and compare the Vertebral Heart Size (VHS) Cardio-Thoracic Rate (CTR) in normal Wistar Rats. size organs chest cavity heart can be measured by taking thorax radiographs. Thorax radiographs 85 male rats were taken under anesthesia, VHS CTR calculated digital environment. mean 7.22 mm right lateral position 7.34 left position. In radiography ventrodorsal...

In-plane uniaxial pressure has been shown to strongly tune the superconducting state of Sr2RuO4 by approaching a Lifshitz transition and associated Van Hove singularity (VHS) in density states. At VHS, $T_c$ in- out-of-plane upper critical fields are all enhanced, latter changed its curvature as function temperature from convex concave. However, due strain inhomogeneity it not possible so far d...

An unusual quasi-two-dimensional heavy band mass van Hove singularity (vHs) lies very near the Fermi energy in MgCNi3, recently reported to superconduct at 8.5 K. This compound is strongly exchange enhanced and unstable to ferromagnetism upon hole doping with approximately 12% Mg-->Na or Li (i.e., 0.04 hole/Ni). We identify an essentially infinite mass along the M-Gamma line, which accounts for...

Objective: This study aimed to evaluate the vaccine hesitancy, anti-vaccination, and anxiety levels of medical secretaries during pandemic.
 Methods: cross-sectional was conducted on 161 working at time Study. Sociodemographic characteristics form, Coronavirus Anxiety Scale (CAS), Vaccine Hesitancy (VHS) adapted pandemic, Anti-vaccination (AVS) were used in questionnaire form collect data ...

PURPOSE The condition in which visual hallucinations (VHs) are solely associated with a visual impairment is termed Charles Bonnet Syndrome (CBS). The study was undertaken to investigate whether the extent of visual acuity (VA) loss and central visual field loss predisposes a patient with age-related macular degeneration (AMD) to develop a CBS VH and, in addition, whether the progression in los...

BACKGROUND Non-alcoholic fatty liver disease (NAFLD) and dyslipidemia are closely related. Diet plays an important role in the progression of these diseases, but the role of specific dietary components is not completely understood. Therefore, we investigated the role of dietary sucrose and fat/cholesterol on the development of dyslipidemia and NAFLD. METHODS Seventy female guinea pigs were bl...

The main problem of private schools is the difficulty finding new learners (NL), exacerbated by Covid-19 pandemic, making even more slumped, including Centers Excellence Vocational High School (VHS CoE). Research objectives to analyze; (1) promotion strategies for VHS CoE, (2) impact CoE on interest NL, and (3) benefits CoE. Qualitative descriptive research methods. sample was four Stages resea...
