Two hundred and thirty three Penan households from the Silat area, Ulu Baram and the Tutoh of the Fourth Division, Sarawak, were studied with regards to the prevalence of endemic goitre and the consumption of iodised salt. Of the 343 Penan women aged 15 years and above who were examined, 60.6% had goitres. The serious nature of this, in the case of the Penans, is indicated by the fact that 39.3...

Salt deposits are commonly regarded as ideal hosts for geologic energy reservoirs. Underground cavern construction-induced damage in salt is reduced by self-healing. Thus, studying the influencing factors on such healing processes is important. This research uses ultrasonic technology to monitor the longitudinal wave velocity variations of stress-damaged rock salts during self-recovery experime...

Creep phenomenon in rock engineering plays a key role in development of underground spaces as they must be stable enough for a long period of time. Current research involved designing and manufacturing of a new creep testing machine. The equipment is capable to perform simultaneous light-duty creep tests on more than one cylindrical rock samples at a very low cost.To evaluate the equipment’s pe...

Salt is a substance with many uses, including as condiment for our food. also rock, and it can be found underground in places around the world. What makes rock salt fascinating that, over hundreds to millions of years, that flows! Over long periods time, behaves bit like honey—like thick, viscous liquid. This means change shape faster than other rocks squeezed surface toothpaste out tube. flow ...

underground caverns in rock salt deposits are the most secure disposal method and a type of gas-storing facility. gas storage plays a vital role in ensuring that a strategic relationship is secured between an established energy infrastructure provider and a midstream energy company. the fischells brook area is a pillow-shaped body of salts located in the st. george's bay area of southwest newfo...
