Natural life history of cephalopods have been puzzling marine biologists for a long time. Fishery scientists also met with great difficulty in managing resources of squids as well as cuttlefishes. The lack of the accurate equation defining growth through time is one of the major reasons. This was due mainly to no stable characteristic for age determinations. It was known that in anatomy, stripe layers of cuttlebone are similar in embryonic development as shells of the bivalve, which has been use...

Due to the expense and logistics involved with operating real remotely operated vehicles (ROV), training and practice is often difficult to obtain. Therefore, many researches were conducted to increase ROV pilots experiences through virtual reality. However, most of the training systems that are in use today can only be controlled by a single operator. When two or more ROVs work in a same area, it needs proper concordance among pilots in order to avoid accidents such as collision or cable entang...

In this paper we developed an automatic sampling device which is capable of taking samples of the substrates at pre-programmed schedule and storing the samples for retrieval. For the reason that the sampler is operated in a severe ocean environment, the first design consideration is to use mechanisms and parts as simple as possible to reduce the risk of failure. Another primary concern is to make sure the design can preserve sediment securely in water. Besides, other considerations include size,...

Previous research shows that dissolved P losses in runoff are well related to soil test P (STP), thus, various P loss prediction models incorporate the use of a STP vs. runoff DRP relationship. However, the relationship between STP and runoff DRP will vary based on soil type due to differences in soil properties. The purposes of the first two studies were to (i) investigate the effect of soil mineralogy on P sorption behavior and dissolved P in runoff and (ii) determine if any simple soil test e...

Translational and rotational motion are coupled for spacecraft performing formation flying missions. This motion is coupled because orbital control is dependent on the spacecraft attitude for vectored thrust. Formation flying spacecraft have a limited mass and volume for propulsion systems. We want to maximize the efficiency of the spacecraft, which leads to minimizing the error introduced by thrusting in the wrong direction. This thrust direction error leads to the need for a coupled attitude a...

The strength and behavior of composite slabs are governed by the shear interaction between the concrete and the steel deck. The interaction property depends on several factors and it is not possible to express the relationship from a purely analytical basis. As such, analysis and design methods available today use the interaction property derived from full scale performance tests. In numerical modeling, the interaction property is obtained from a variety of elemental push off tests which, for th...

Abstract. Nitrification, the chemoautotrophic process via which ammonium-nitrogen (NH4-N) is converted to nitrate-nitrogen (NO3-N), is an important nitrogen (N) transformation in stream ecosystems. Experimental addition of dissolved organic carbon (DOC) has been shown to inhibit rates of nitrification, and rates have been stimulated by NH4-N addition. Insights regarding the role of particulate organic matter (POM) in this scenario could further enhance our understanding of linkages between ecosy...
