attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (tpe) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. in order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic modul...

Purpose: This paper investigates how entrepreneurial finance in Qatar affects the performance of small and entrepreneurship businesses (SEB). It is first study examining financial decisions SEB Qatar, illustrating advantages disadvantages traditional innovative sources finance. In addition, we investigate impact different funding on three dimensions performance: financial, marketing internal bu...

The objective of this work is to compare various ET models based on a standard dataset. We selected 9 ET models for comparison, including three surface energy balance residual models (SEBS, TSEB-P and TSEB-S), four Penman-Monteith models (PM-Mu, PM-Yuan, PM-Sun and PM-SW), one Priestly-Taylor model (PT-Fi) and one semi-empirical statiacital model (ST). ET is evaluated using surface climate data...

The Weishan Irrigation Zone along the lower reaches of the Yellow River consists of a total irrigated area of 3600 ha. The region has an average annual rainfall of 500–600 mm, with 60–70% of local rainfall occurring during the summer, and with less than 15% in spring. The water deficit during the spring affects the winter wheat growth from March to early June, which is a major growth period sig...

Plastics occupy wide place in the applications of automotive, electronics and house goods. Especially reinforced plastics become popular because of their high strength besides their advantages of low weight and easy manufacturability. In this study, mechanical and morphological properties of polypropylene (PP) and high density polyethylene (HDPE) matrix composites reinforced with surface modifi...

Cervical cancer chemoprevention agents under study include diet and micronutrients (particularly beta-carotene, folate, and vitamins A, C, and E); medications such as retinoids (retinyl acetate gel, all-trans-retinoic acid, and 4-hydroxyphenylretinamide) that are chemically related to micronutrients; and other chemopreventives meant to affect the carcinogenic process at the cellular level, incl...

Flexible strain sensors have attracted extensive attention due to their potential applications in wearable electronics and health monitoring. However, it is still a challenge obtain flexible with both high stretchability wide linear sensing range. In this study, styrene-ethylene-butadiene-styrene copolymer/carbon nanotubes (SEBS/CNTs) composite fiber which showed electrical conductivity was fab...

The droplet interface bilayer (DIB) is a promising technique for assembling lipid membrane-based materials and devices using water droplets in oil, but it has largely been limited to laboratory environments due to its liquid construction. With a vision to transform this lab-based technique into a more-durable embodiment, we investigate the use of a polymer-based organogel to encapsulate DIBs wi...
