An experimental study was made of the ignition process of single droplets of binary mixtures subjected to a laminar flat flame propagating through a lean homogeneous propane/air mixture at constant pressure. Binary fuels consisting of n-hexane and n-hexadecane or n-dodecane, and benzene and n-hexadecane were tested. Water-emulsified liquids consisting of n-dodecane, and pure fuels like n-hexane, n-octane, n-dodecane, and n-hexadecane, were used as well. A combustion chamber made of a transparent ...

Abstract The aim of this study was to evaluate whether frailty was associated with 6-month mortality in older adults who were admitted to the intensive care unit (ICU) with an illness requiring emergency care. The investigation was a prospective, multi-center, observational study conducted among the ICUs of 17 participating hospitals. Patients ≥ 65 years of age who were admitted to the ICU directly from an emergency department visit were assessed to determine their baseline Clinical Frailty Scale (CFS) ...

An experimental study has been made of the ignition process of fuel droplet array subjected to a laminar fiat flame propagating through a lean homogeneous propane-air mixture at constant pressure. A combustion chamber made of a transparent duct was installed with spark electrodes, a pair of fine quartz fibers to suspend fuel droplets and a shutter to allow the burned gas to flow out. A high speed video camera was provided for the photographic observation of the droplets ignited by the propagating ...

To date, the monohexosylceramides present in the eukaryotic alga Euglena gracilis has not been reported. In this study, we extracted and purified a lipid fraction that eluted similarly to other reported monohexosylceramides. The structural determination of the lipid fraction revealed a monohexosylceramide ( m/ z = 889.5 and a loss of m/ z = 162), corresponding to the formula C 54 H 99 O 8 N having moieties corresponding to a monohexose (C 6 H 12 O 6 ), a 9-methyl-4,8-sphingadienine (C 19 H 37 O 2 N), and a ...

Abstract Background Evidence indicates frailty before intensive care unit (ICU) admission leads to poor outcomes. However, it is unclear whether quality of life (QOL) and activities of daily living (ADL) for survivors of critical illness admitted to the ICU via the emergency department remain consistent or deteriorate in the long-term compared to baseline. This study aimed to evaluate long-term QOL/ADL outcomes in these patients, categorized by the presence or absence of frailty according to Clinical ...

Summary A recent increase in the demand for pineapple necessitates the development of new varieties with superior flavour quality. In this study, we characterised the volatile profiles of three new Okinawan pineapple breeding lines using gas chromatography (GC)–mass spectrometry (MS)‐based electronic nose (e‐nose), glycosylated volatiles, and alcohol‐acyltransferase (AAT) activity measurements. The volatile profiles of the fruits were selected using the GC–MS‐e‐nose and visualised using multivariate ...

Rationale: It has been reported that preoperative reduced skeletal muscle mass and skeletal muscle mass loss during adjuvant chemotherapy are associated with discontinuation of adjuvant chemotherapy. However, the relationship between visceral fat mass and compliance has not yet been investigated. In this study, we investigated the impact of low preoperative visceral fat mass on compliance and relapse-free survival (RFS) after gastrectomy in gastric cancer patients.
