For individuals with vision-touch synaesthesia, the sight of touch on another person elicits synaesthetic tactile sensation on the observer's own body. Here we used the traditional rubber hand paradigm (Botvinick and Cohen, 1998) and a no-touch rubber hand paradigm to investigate and to authenticate synaesthetic tactile sensation. In the traditional rubber hand paradigm, the participant views a...

nanocomposite vulcunizates based on styrene-butadiene rubber (sbr), organoclay and a conventional sulfur curing system were prepared by melt blending process in an internal mixer. in order to study the effects of the type of interfacial compatibilizer on the properties of sbr and clay nanoparticles,three types of compatibilizers, maleic anhydride grafted ethylene-propylene diene rubber (epdm-g-...

Natural rubber from Hevea brasiliensis is a high molecular mass polymer of isoprene units with cis-configuration. The enzyme responsible for the cis-1,4-polymerization of isoprene units has been idengified as a particle-bound rubber transferase, but no gene encoding this enzyme has been cloned from rubber-producing plants. By using sequence information from the conserved regions of cis-prenyl c...

Hevea brasiliensis is the most widely cultivated species for commercial production of natural rubber (cis-polyisoprene). In this study, 10,040 expressed sequence tags (ESTs) were generated from the latex of the rubber tree, which represents the cytoplasmic content of a single cell type, in order to analyse the latex transcription profile with emphasis on rubber biosynthesis-related genes. A tot...

Soils are called problematic soils when they do not have sufficient bearing strength to provide a founda-tion for the structures be built on them and these types of need improved with appropriate methods depending their properties. Improvement applied strengthen often cause financial burden. Recently, there studies about use waste rubber tires, which pose an environ-mental risk during storage, ...

MYB transcription factors hold vital roles in the regulation of plant secondary metabolic pathways. Laticifers in rubber trees (Hevea brasiliensis) are of primary importance in natural rubber production because natural rubber is formed and stored within these structures. To understand the role of MYB transcription factors in the specialized cells, we identified 44 MYB genes (named HblMYB1 to Hb...

The addition of cork to a natural rubber compound and the vulcanization parameters were studied in terms their influence on properties cork–rubber materials. characterization different compounds was carried out included determination mechanical related application composites as vibration isolation pads, such static dynamic behavior under compressive loading. Statistical methods, ANOVA regressio...

BACKGROUND Primary tracheal tumors occur infrequently, accounting for less than 0.1% of all tumors. Adenoid cystic carcinoma (ACC) is the second most common type of malignancy of the trachea after squamous cell carcinoma (SCC). Little has been reported on the risk factors for tracheal ACC. The purpose of this study is to describe a case of tracheal ACC in a patient who had been exposed to rubbe...

In alpine regions, the durability of asphalt pavement is worse due to harsh climate. However, crumb rubber modified has potential improve pavement. Based on matrix asphalt, rubber, Trans-Polyoctenamer Rubber Reactive Modifier (TOR), and an orthogonal test, preparation scheme suitable for regions was obtained. The selected 30 mesh, content 24% quality asphalt. Shearing time 60 min, temperature 2...

Natural rubber is used as an important raw material by the pressure sensitive adhesives industry. However, the normal quality variation is relatively high compared to synthetic polymer alternatives. This paper discusses measurements of the magnitude and nature of this natural rubber quality variation using a special dynamic mechanical rheological tester. Also the paper discusses some of the cau...
