The Mnemonic Correction Becomes Meaningful Through Focus Group Discussion in Chemistry Learning

JTK (Jurnal Tadris Kimiya), 2022
One of the concerns in the learning process is the meaning of writing mnemonics to help students memorize chemistry concepts. The research aimed to correct mnemonics in learning presentation by prospective chemistry teachers' students to be meaningful ...

A "Periodic Table" for Supersymmetric M-Theory Compactifications

, 2002
We develop a systematic method for classifying supersymmetric orbifold compactifications of M-theory. By restricting our attention to abelian orbifolds with low order, in the special cases where elements do not include coordinate shifts, we construct a ...

The location and composition of Group 3 of the periodic table [PDF]

Foundations of Chemistry, 2020
AbstractGroup 3 as Sc–Y–La, rather than Sc–Y–Lu, dominates the literature. The history of this situation, including involvement by the IUPAC, is summarised. I step back from the minutiae of physical, chemical, and electronic properties and explore considerations of regularity and symmetry, natural kinds, and quantum mechanics, finding these to be ...

Non periodic Ishibashi states: the su(2) and su(3) affine theories [PDF]

, 2002
We consider the su(2) and su(3) affine theories on a cylinder, from the point of view of their discrete internal symmetries. To this end, we adapt the usual treatment of boundary conditions leading to the Cardy equation to take the symmetry group into ...

Model Equation Based on the 8 Groups and the 7 Periods in the Periodic Table of Elements

International Research in Education, 2021
The periodic table of chemistry contains all synthetic and naturally occurring elements. The elements are arranged in seven horizontal periods from left to right with increasing atomic number. The periodic table is divided into two groups: metals and nonmetals, within elements moving from left to right, the elements get less metallic, culminating in ...

Patient Activation in Childhood, Adolescent, and Young Adult Cancer Survivors: Current Insights and Implications for Survivorship Care—A Systematic Review From the e‐QuoL Project

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Patient activation—encompassing knowledge, confidence, and skills in managing individual's health—is a cornerstone of person‐centered care. However, its significance among childhood, adolescent, and young adult cancer survivors (CAYACS) remains unexplored. This article examines the application of the 13‐item Patient Activation Measure (

The Periodic Table and Kinetics?

CHIMIA, 2019
Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later.

Physical properties and defect processes of M3SnC2 (M = Ti, Zr, Hf) MAX phases: Effect of M-elements [PDF]

, 2018
We have employed density functional theory calculations for determining intrinsic defect processes and structural, elastic, and electronic properties of recently synthesized Sn-containing 312 MAX phases M3SnC2 (M = Ti, Zr, Hf) including Debye temperature,

Unheard and Under‐Supported: Health‐Related Quality of Life in Children, Adolescents, and Young Adults With Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
Abstract Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy affecting millions of individuals worldwide. The clinical expression and psychosocial burden of SCD vary widely across geographical, cultural, and healthcare system contexts, underscoring the need for setting‐specific approaches to assessment.
