BACKGROUND Clinical observations suggest that tolerance to heat stress may be impaired in patients with cardiovascular diseases, particularly those associated with impaired ventricular function and congestive heart failure (CHF). However, thermoregulatory function during a controlled heat stress challenge in patients with CHF has not been studied. METHODS AND RESULTS To test the hypothesis th...

Auckland has a temperate climate with comfortable warm, dry summers and mild, wet winters. Auckland house design not only focus on winter thermal performance and indoor thermal condition, but also indoor moisture control, which is closely related to indirect health effects such as dust mites, fungi, etc. Most Auckland houses are designed to use temporary heating for winter indoor thermal comfor...

This study focuses on the impact of school building design factors on winter extra energy consumption which mainly includes space heating, water heating and other appliances related to winter indoor thermal conditions. A number of Auckland schools were randomly selected for the study which introduces a method of using real monthly energy consumption data for a year to calculate winter extra ene...

Previous investigations have assumed that embryos lack the capacity of physiological thermoregulation until they are large enough for their own metabolic heat production to influence nest temperatures. Contrary to intuition, reptile embryos may be capable of physiological thermoregulation. In our experiments, egg-sized objects (dead or infertile eggs, water-filled balloons, glass jars) cooled d...

A continuous flow sonochemical reactor was developed capable of producing metastable cadmium sulfide (CdS) nanoplatelets with thicknesses at or below 10nm. The continuous flow sonochemical reactor included the passive in-line micromixing of reagents prior to sonochemical reaction. Synthesis results were compared with those from reactors involving batch conventional heating and batch ultrasound-...

Significant progress has been made on maximising passive solar heat gains to building spaces in winter. Control of the space heating in these applications is complicated due to the lagging influence of the useful solar heat gain coupled with the wide range of construction materials and heating system choices. Additionally, and in common with most building control applications, there is a need t...

Passive thermography is commonly used for composites load testing to detect damage formation as a function of the applied load. The advantages passive are real time implementation, large area coverage, and noncontact measurement. able location size, however, depth has been challenge quasistatic loading. Recent work shown that during loading produces heating composed two heat generation componen...

Substances undergoing endothermic reactions are of wide interest in the development of materials oriented to fire passive protection. These components can be used as aggregates in usual building materials in order to improve the response under high temperature scenarios. The mechanism of action is based on the absorption of part of the generated heat of combustion by the corresponding endotherm...

The relationships of pulmonary function with age, duration of asthma and social factors were studied in 630 asthmatics. Pulmonary function was assessed by peak flow rate at routine attendance (actual function). Persistence of obstruction was demonstrated by a trial of corticosteroids where necessary. The best obtainable peak flow rate was recorded (maximum function). Unrelieved potentially reve...

The objective of this study was to identify what measures are taken to prevent hypothermia in the intraoperative period. This is a non-experimental, descriptive-exploratory prospective study. To do this, a data collection instrument was developed, which was submitted to appearance and content validations. The sample consisted of 70 patients. The measure that was most commonly used in the operat...
