Dementia Incidence in Individuals With Parkinson's Disease in the Framingham Heart Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Limited information exists on incident dementia in individuals with Parkinson's disease (PD) in US community‐based samples. We examined cognitive statuses and PD diagnoses of 183 individuals in the Framingham Heart Study (FHS) to establish incident dementia, mortality rates, associations with sex, age at PD onset, and education level.

Junkers Type Gas Calorimeter & Burner

open access: yes, 1910
This continuous flow gas calorimeter is of the Junkers 1209 type. The burning of the gas in a standard burner heats a stream of water from a measured initial temperature to a measured final temperature.

A 17 Year Old With Developmental Delay Presenting With Increasing Confusion and Imbalance

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Methylmalonic acidemia is an autosomal recessive genetic disorder primarily caused by defects in methylmalonyl‐CoA mutase and cobalamin (vitamin B12) metabolism. These defects disrupt the tricarboxylic acid cycle and oxidative phosphorylation, leading to the abnormal accumulation of metabolic products such as methylmalonic acid, propionic acid,

The clinical significance of gas-containing liver abscesses converting from total gas content to gas and fluid content: a case report*

open access: yesInternational Journal of Clinical Practice, 2005
The first case of gas-containing liver abscesses converting from total gas content to gas and fluid content is reported, and the clinical significance of such a conversion is emphasised. A 58-year-old diabetic woman suffered from fever and chill due to totally gas-containing liver abscesses shown by computerised tomography (CT).

Vertical and lateral variation of gas content associated with coal seams [PDF]

open access: yes, 2015
Vertical and lateral gas content variation associated within a coal seam and its relation to porosity and geology was researched. Several seams of high sub-bituminous and bituminous coal volatile C from Amaga formation were selected. Channel samples were

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
