Mutations in the torpedo gene, which encodes the fruitfly homolog of the epidermal growth factor receptor (DER), disrupt a variety of developmental processes in Drosophila. These include the survival of certain embryonic ectodermal tissues, the proliferation of the imaginal discs, the morphogenesis of several adult ectodermal structures and oogenesis, torpedo is genetically complex: a number of...

In the torpedo attack, appropriate firing distance is key to ensure hit target, it’s necessary used within maximum distance. Therefore, under premise of known conditions, determine and be familiar with factors that affect value influencing rules each factor. Based on model acoustic homing torpedo, expression established, main affecting are obtained. Through simulation, influence analyzed quanti...

Particle filter is proposed for tracking a torpedo using bearings-only measurements when torpedo is attacking an ownship. Towed array is used to generate torpedo bearing measurements. Ownship evasive maneuver is used for observability of the bearings-only process. Particle filter combined with Modified Gain Bearings-Only Extended Kalman Filter is used to estimate torpedo motion parameters, whic...

Torpedoes play an irreplaceable role in naval warfare; therefore, it is significant to study the dynamic response of direct navigation torpedoes. In order torpedoes under different Munk moment coefficients, equation established based on momentum theorem and theorem. The linear motion mathematical model obtained. relationship between torpedo coefficient derived. straight-line moments established...

Creatine kinase isoenzymes from Torpedo californica electric organ, skeletal muscle, and brain were purified and characterized. Torpedo electric organ and skeletal muscle creatine kinase have identical apparent Mr, electrophoretic mobility, and cyanogen bromide fragments. The electrophoretic mobility of the Torpedo creatine kinase was anodal as compared to mammalian MM creatine kinase. No creat...

This paper introduces the world’s first laser profile measurement system for the refractory lining of hot torpedo ladles, the LaCam®. The torpedo measuring system allows immersion of a laser head into a hot torpedo ladle with surrounding temperatures of more than 1,000°C. Benefits include improved safety, increased ladle availability and capacity, extended refractory life, and cost savings in e...

In this research, a stochastic simulation based design tool that facilitates design in a dynamic environment is developed. The simulation includes a full dynamic model of an Autonomous Underwater Vehicle (AUV) that was developed to evaluate the effectiveness of such a craft given a set of physical attributes. These attributes include but are not limited to: speed, mass, moments of inertia, cont...

Antisera against purified acetylcholine receptors from the electric tissues of Torpedo californica and of Electrophorus electricus were raised in rabbits. The antisera contain antibodies which bind to both autologous and heterologous receptors in solution as shown by an immunoprecipitation assay. Antibodies in both types of antisera bind specifically to the postjunctional membrane on the innerv...

When the four subunits of the Torpedo californica nicotinic acetylcholine receptor (AChR) are expressed in mammalian fibroblasts, they properly assembly into alpha 2 beta gamma delta pentamers only at temperatures lower than 37 degrees C (Claudio, T., W. N. Green, D. S. Hartman, D. Hayden, H. L. Paulson, F. J. Sigworth, S. M. Sine, and A. Swedlund. 1987. Science (Wash. DC). 238:1688-1694). Expe...
