Background and aims: Heat stress is one of the most important occupational hazards that threaten the health of employees in many workplaces. This hazard is more important in the industries with hot processes, such as rubber industry. Therefore, control of this harmful agent is one of the essential measures and priorities of manager in these industries. The purpose of this study was to identifyi...

Kazakh dandelion (Taraxacum kok-saghyz, Tk) is a rubber-producing plant currently being investigated as a source of natural rubber for industrial applications. Like many other isoprenoids, rubber is a downstream product of the mevalonate pathway. The 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) enzyme catalyzes the conversion of 3-hydroxy-3-methylglutaryl-CoA to mevalonic acid, a key regulat...

The concept of a ‘‘bound rubber’’ phase extending over nanometre-scale distances from the interface of rubber-particle nanocomposites is generally accepted. However, the thickness and elastic properties of this interphase have not been confirmed by direct experimental observation. Here, we demonstrate the existence of bound rubber in hydrogenated nitrile butadiene rubber (HNBR)–carbon black com...

The objective of this study was to evaluate the opinions and attitudes of dentists toward the use of rubber dam during various restorative procedures in their dental practices. A structured questionnaire was designed, and distributed to 300 dentists and those that were fully completed were collected for analysis. The collected informations about the opinions and attitudes of dentists toward the...

Consecutive extraction of latex and natural rubber from the roots of rubber-bearing plants such as Taraxacum kok-saghyz (TKS), Scorzonera tau-saghyz (STS), and Scorzonera Uzbekistanica (SU) were carried out. Latex extraction was carried via two methods: Blender method and Flow method. The results of latex extraction were compared. Cultivated rubber-bearing plants contained slightly higher latex...

To improve the blast resistance of a wall system, it is necessary to enhance its energy absorption capabilities and/or increase its mass. Much research has been performed on improving the ductility, and thus the resistance, of a wall system using elastic materials externally attached to the tension side of a wall. This project investigated the static resistance of wall systems with elastic mate...

In this paper, the effect of reclaimed rubber modification on the rheological characteristics of asphalt binders is studied. Reclaimed rubber with the extent of 12, 16 and 20 is added to the neat asphalt binder and then shear complex modulus is obtained for neat and modified asphalt binder via Dynamic Shear Rheometer (DSR) test. Using Christensen-Anderson- Marasteanu (CAM) model, master curves ...

This study investigates basin-scale hydrologic implications of the replacement of forest-dominated land cover by rubber plantations in Montane Mainland Southeast Asia. The paper presents a new method for estimating the water demand of rubber and consequently water losses to the atmosphere through rubber evapotranspiration (ET). In this paper we argue that rubber ET is energy-limited during the ...

Renewed interest in the identification of alternative sources of natural rubber to Hevea brasiliensis has focused on the Compositae family. In our search for Compositae models for rubber synthesis, we extracted latex from stems of two lettuce species: Lactuca serriola, prickly lettuce, and Lactuca sativa cv. Salinas, crisphead lettuce. Both species contained cis-1,4-polyisoprene rubber in the d...

Electronic systems that offer elastic mechanical responses to high-strain deformations are of growing interest because of their ability to enable new biomedical devices and other applications whose requirements are impossible to satisfy with conventional wafer-based technologies or even with those that offer simple bendability. This article introduces materials and mechanical design strategies ...
