Abstract:

A monitoring instrument of environment condition is described in this paper, which uses the LPC2368 as the controller. The acquisition of environmental condition is realized by using SHT11, which is a digital temperature and humidity sensor. A DS1302 is used as the real time reference clock device, and the time message is displayed on the LCD together with the environment temperature and humidity. As if the temperature or humidity is beyond the setting range, the alarm light and sound will be switched on to inform the manager. At the same time, the alarm message could be sent out to other moni

Abstract Flexible humidity sensors are effective portable devices for human respiratory monitoring. However, the current preparation of sensitive materials need harsh terms and the small production output limits their practicability. Here, we report a synthesis method of single-crystal BiOBr nanosheets under room temperature and atmospheric pressure based on a sonochemical strategy. A flexible humidity sensor enabled by BiOBr nanosheets deliver efficient sensing performance, a high humidity sensitivity (I g/I 0 = 550%) with relative humidity from 40% to 100%, an excellent selectivity, and a de

Abstract:

Hygrothermal modelling is increasingly used to inform building envelope design. A key input for these calculations is the material’s vapour diffusion properties. Respecting a growing international concern, this research has questioned the appropriateness of the current test method to establish construction material for vapour diffusion properties. This article reports on the empirical measurement of the vapour diffusion properties of two vapour-permeable building membranes commonly used in Australia residential systems when subjected to variable relative humidity conditions.

The present results showed that cooling water (CLW) was more easy to be contaminated than the condensed water (CDW) of central aircondition by Legionella in high air temperature and humidity, and the Legionella was not observed in all sample of the cold medium water (CMW) of central aircondition. The air temperature and relative humidity have significant impact on Legionella. No sample was positive while the average relative humidity was lower than (77.08 ± 1.30) %, and the high value of the ratio of positive samples occurred while the average air temperature and the average relative humidity

Abstract:

The environmental experiments of the thermal cycling (-40~125°C) and the high temperature/humidity (85°C, 85%RH) aging were used to evaluate the reliability of the specimens bonded with ACFs. It was found that the high temperature/humidity was the harshest condition to the ACFs bonding. The DSC testing and interfacial stresses analysis has been done under the high temperature/humidity condition. The mechanisms of the bonding strength decrease were investigated.

Two years experiment was carried out to study the impact of climatic factors on growth and quality of low chilling peach [Prunus persica (L.) Batsch] cultivar, viz. Early Grande. The results reveal that plant volume of Early Grande was positively influenced by maximum and minimum temperature at P1 stage. Minimum temperature at P3 stage exerted positive impact on plant volume, while plant volume was negatively related to humidity at P2 and P3 stages. Shoot extension growth was also negatively influenced by relative humidity at P3 stage. During second year, plant volume and shoot extension growt

Abstract:

To improve the reliability and design of body armor, it is imperative to understand the failure modes and the degradation rates of the materials used in armor. Despite the best efforts of manufacturers, some vulnerability of armor materials to aging due to hydrolytic or oxidative environments is expected and may result in the degradation of material properties such as tensile strength. In this work, p-aramid yarns from two manufacturers were exposed to environmental conditions of various fixed temperature and humidity combinations. The maximum temperature and humidity condition was 70℃ and 76%

This paper describes a new electro-active actuator based on cellulose and poly(3-hydroxybutyrate) (PHB) blend film that can produce high bending displacement in room humidity condition. Cellulose based actuator has been reported as a smart material that has merits in terms of lightweight, dry condition, biodegradability, sustainability, large displacement output and low actuation voltage. However, its actuator performance is very sensitive to humidity, which requires high humidity condition for the maximum actuator performance. To overcome this drawback, we introduce cellulose-PHB blend film b

Creep, as one of the most important properties of concrete, has important influences on concrete structures. In present domestic researches, studies on humidity diffusion in concrete are relative inadequate; and few models can take comprehensive consideration on humidity factors. According to humidity diffusion theory of concrete, this paper studied the distribution of humidity field within concrete at constant humidity condition by using finite element method. Based on the drying creep of the Model B3, this paper analyzes the effects of humidity field on creep of RC beams.

AbstractIncreases in the severity of heat stress extremes are potentially one of the most impactful consequences of climate change, affecting human comfort, productivity, health, and mortality in many places on Earth. Heat stress results from a combination of elevated temperature and humidity, but the relative contributions of each of these to heat stress changes have yet to be quantified. Here, conditions for the baseline specific humidity are derived for when specific humidity or temperature dominates heat stress changes, as measured using the equivalent potential temperature (θE).
