Imaging the ring opening reaction of 1,3-cyclohexadiene with MeV ultrafast electron diffraction

We resolve the structural dynamics of the ultrafast photoinduced ring opening reaction of 1,3-cyclohexadiene in space and time employing megaelectronvolt gas phase ultrafast electron diffraction. We, furthermore, observe coherent large ampl...

Pengaruh Model Project Based Learning Berbantuan Media Virtual Terhadap Penguasaan Konsep Peserta didik pada Materi Alat-alat Optik

Learning physics should be able to provide an understanding physics of abstract concepts. One of the efforts being made to improve the learning of Physics is to use appropriate learning model. This study aims to improve the student’s...

Fixed field alternating gradient accelerator with small orbit shift and tune excursion

A new design principle of a nonscaling fixed field alternating gradient accelerator is proposed. It is based on optics that produce approximate scaling properties. A large field index k is chosen to squeeze the orbit shift as much as possib...

Impact of solvents on doctor blade coatings and bathocuproine cathode interlayer for large-area organic solar cell modules

Efforts to commercialize organic solar cells (OSCs) by developing roll-to-roll compatible modules have encountered challenges in optimizing printing processes to attain laboratory-level performance in fully printable OSC architectures. In t...

The Relationship between Exercise and Salivary Oxidative Stress: A Systematic Review

Salivary content has been reported as a potential biomarker for oxidative stress assessments especially in context of exercise-induced oxidative stress. This systematic review following PRISMA guidelines aimed to evaluate the effects of phy...

Culture, emotion, and cognition: Understanding the psychological dynamics of Chinese sports with emotional regulation skills and cognitive reappraisal

This study illuminates the complex relationship between cultural orientation towards collectivism, emotional regulation skills, cognitive reappraisal ability, sports engagement, perceived coach support, and sports self-efficacy in Chinese a...

Floristic diversity and structural parameters on the forest tree population in the Luki biosphere reserve, Democratic Republic of Congo

Tropical rainforests play an important role in the global Eco-climatic balance and its sustainable management is a major concern that has attracted the attention of researchers. The Luki biosphere reserve, while under a status of protected ...

METHOD OF CONVERSATION IN PSYCHODIAGNOSTICS BY PROJECTIVE METHODS IN WORKING WITH STUDENTS OF NAUTICAL SPECIALTIES

Is health-related quality of life the same for elderly polish migrants, Turkish migrants and German natives? Testing the reliability and construct validity of the Sf-36 health survey in a cross-cultural comparison

Objective: The Sf-36 is the most widely used instrument to measure health-related quality of life (HRQoL) with the most convincing evidence of both internal consistency and test–retest reliability. In addition, it is appropriate for use amo...

Paths to Diversity: A Simulation of Conformity in Environments with Different Geometries

The geometry of the environment can affect numerous psychological, social, and ecological processes. But its roles in social learning and the dynamics of descriptive norms remain unclear. Here we use agent-based modeling to explore how envi...

Children’s memory “in the wild”: examining the temporal organization of free recall from a week-long camp at a local zoo

Abstract Free-recall paradigms have greatly influenced our understanding of memory. The majority of this research involves laboratory-based events (e.g., word lists) that are studied and tested within minutes. This literature shows that adu...
