As compared with other candidate carbon sequestration technologies, mineral carbonation offers the unique advantage of permanent disposal via geologically stable and environmentally benign carbonates. The primary challenge is the development of an economically viable process. Enhancing feedstock carbonation reactivity is key. Heat activation dramatically enhances aqueous serpentine carbonation ...

Unique and interesting gait of the snakes makes them able to crawl, climb a hill, climb a tree by winding and move on very slippery floor. Snake does not have hands and legs, however it has many function. It is useful to consider and understand the mechanism of the gait of the snakes for mechanical design and control law of snake robots. Snake robots is active code mechanism and is usefule for ...

397 holstein dairy cows were used to determine locomotion score, lameness prevalence and its relationship with age of the animal and body condition score (bcs). locomotion score was determined using seven gait properties of animal. the results showed that more than 56% of cows in the herd had no locomotion problems. more than 40% of cows were placed in the group of suspected subclinical lamenes...

[1] Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analyses of B and Li in serpentinized peridotites from the Feather River Ophiolite (California) indicates that B is enriched in serpentine minerals compared to the whole-rock and less altered olivine grains, while Li in serpentine is depleted or comparable to whole-rock Li. The high B contents of serpentine minerals cor...

Plants on serpentine soils provide extreme examples of adaptation to environment, and thus offer excellent models for the study of evolution at the molecular and genomic level. Serpentine outcrops are derived from ultramafic rock and have extremely low levels of essential plant nutrients (e.g., N, P, K, and Ca), as well as toxic levels of heavy metals (e.g., Ni, Cr, and Co) and low moisture ava...

Adaptations to particular stresses may occur only in populations experiencing those stresses or may be widespread within a species. Nickel hyperaccumulation is viewed as an adaptation to high-Ni (serpentine) soils, but few studies have determined if hyperaccumulation ability is restricted to populations from high-Ni soils or if it is a constitutive trait found in populations on both high- and l...

Rauwolfia species (Apocynaceae) are medicinal plants well known worldwide due to its potent bioactive monoterpene indole alkaloids (MIAs) such as reserpine, ajmalicine, ajmaline, serpentine and yohimbine. Reserpine, ajmalicine and ajmaline are powerful antihypertensive, tranquilizing agents used in hypertension. Yohimbine is an aphrodisiac used in dietary supplements. As there is no report on t...

The Problem: The problem is to design an autonomous mobile robot that is self-assembling from independently mobile segments. We choose a design inspired by the constitution and motion of snakes or worms. In such a construction, the body of the robot is segmented and each segment can be designed as an autonomous entity, which is able to move and couple with other segments. Several of these segme...
