Thermal stability and oxidation characteristics of α-pinene, β-pinene and α-pinene/β-pinene mixture.

Turpentine is a renewable resource, has good combustion performance, and is considered to be a fuel or promising additive to diesel fuel. This is very important for the investigation of thermal stability and energy oxidation characteristics, because evaluation of energy or fuel quality assurance and use safety are necessary. The main components of turpentine are α-pinene and β-pinene, which have unsaturated double bonds and high chemical activity.

Thermal Stability Evaluation of Resin Acids and Rosin Modified Resins.

Rosin is a sustainable resource, which is mainly composed of resin acid. Rosin-modified resin is widely used in adhesives, inks, coatings, and other fields, and its stability is very important for the production, storage, and use of products. Thermal stability and reactivity of three resin acids (levopimaric acid, neoabietic acid, and dehydroabietic acid) and four rosin-modified resins were studied using an accelerating rate calorimeter (ARC).

Gas-phase reaction mechanism in chemical dry etching using NF and remotely discharged NH/N mixture.

Modeling of dry etching processes requires a detailed understanding of the relevant reaction mechanisms. This study aims to elucidate the gas-phase mechanism of reactions in the chemical dry etching process of SiO layers which is initiated by mixing NF gas with the discharged flow of an NH/N mixture in an etching chamber. A kinetic model describing the gas-phase reactions has been constructed based on the predictions of reaction channels and rate constants by quantum chemical and statistical reaction-rate calculations.

Pool walking may improve renal function by suppressing the renin-angiotensin-aldosterone system in healthy pregnant women.

This study aimed to examine the effect of pool walking on renal function in pregnant women. Fifteen pregnant women (mean gestational age, 37.8 weeks) walked in a pool (depth 1.

Growth Patterns of Neonates Treated with Thermal Control in Neutral Environment and Nutrition Regulation to Meet Basal Metabolism.

Little is known about the growth patterns of low birth weight neonates (<2500 g) during standardized thermal control and nutrition regulation to meet basal metabolism requirements compared to those of non-low birth weight neonates (2500 g and above). We retrospectively identified 10,544 non-low birth weight and 681 low birth weight neonates placed in thermo-controlled incubators for up to 24 h after birth. All neonates were fed a 5% glucose solution 1 h after birth and breastfed every 3 h (with supplementary formula milk if applicable) to meet basal metabolism requirements.

Optimal Thermal Control with Sufficient Nutrition May Reduce the Incidence of Neonatal Jaundice by Preventing Body-Weight Loss Among Non-Low Birth Weight Infants Not Admitted to Neonatal Intensive Care Unit.

Background: Neonatal jaundice is strongly attributable to excess body-weight loss as a result of insufficient calorific intake.

Objectives: To examine the incidence of neonatal jaundice (defined by use of phototherapy) and body-weight loss, as well as their association, among neonates under optimal thermal control with sufficient nutrition, a local protocol for temperature and nutritional regulation.

Methods: We retrospectively identified a cohort of 10,544 neonates (birth weight ≥2,500 g) placed in thermo-controlled incubators for 2 h immediately after birth.
