Ethylene is a stimulant to increase natural rubber latex. After ethylene application, both fresh yield and dry matter of latex are substantially improved. Moreover, we found that ethylene improves the generation of small rubber particles. However, most genes involved in rubber biosynthesis are inhibited by exogenous ethylene. Therefore, we conducted a proteomics analysis of ethylene-stimulated ...

Accurate and up-to-date mapping and monitoring of rubber plantations is challenging. In this study, we presented a simple method for rapidly and accurately mapping rubber plantations in the Xishuangbanna region of southwest China using phenology-based vegetation index differencing. Temporal profiles of the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Atmospher...

Tapping panel dryness (TPD) is a serious threat to natural rubber yields from rubber trees, but the molecular mechanisms underlying TPD remain poorly understood. To identify TPD-related genes and reveal these molecular mechanisms, we sequenced and compared the transcriptomes of bark between healthy and TPD trees. In total, 57,760 assembled genes were obtained and analyzed in details. In contras...

At designing pipeline transport of granulated solid materials, one of the most important parameter is the pressure loss over a given length of pipe. The pressure loss determines the applicable pump as well as the main portion of the operational costs. In the practice the transported solids can be characterized by size, density and shape distributions. Still many of the existing great number of ...

This study examined the factors that influence agricultural production and exports with specific reference to the natural rubber in India. Secondary data was used for this study. Ordinary Least Squares (OLS) technique was used in analyzing the relevant data. The OLS findings revealed that natural rubber production is significantly (p<0.05) by export of natural rubber (β=0.05), stock (β=0.21) an...

The angiogenic properties of natural rubber were evaluated in this work. We have used the chick chorioallantoic membrane assay (CAM) as a model to investigate the influence of the heating on biological activity in rubber membranes and in non rubber fraction as well. Results showed that natural rubber membranes can induce vascularization. It was observed that angiogenesis activity was maximum wh...

On the one hand, it is often assumed that the Rubber Hand Illusion (RHI) is constrained by a structural body model so that one cannot implement supernumerary limbs. On the other hand, several recent studies reported illusory duplication of the right hand in subjects exposed to two adjacent rubber hands. The present study tested whether spatial constraints may affect the possibility of inducing ...

The disposal of used tires is a major environmental problem throughout the world which causes environmental hazards. Crumb rubber is a waste material that is ideal for use in concrete applications. The aim of this study is achieved to use of rubber waste as partial replacement of fine aggregate to produce rubberize concrete in M30 mix. Different partial replacements of crumb rubber (0, 5, 10, 1...

Based on the classical regression model, timevarying coefficient model, unit root, co-integration, Granger causality test, VAR, impulse response and variance decomposition, the dynamic relationship between prices of natural rubber futures in China and Japan has been researched systematically. The following conclusions are gotten through empirical researches: Firstly, there is a stable co-integr...

A granulated cell in human skin has an ultrastructure similar to that of chromaffin cells of the adrenal medulla. This cell is closely associated with unmyelinated axons and may be the site of peripheral store of noradrenaline.
