ADVENTIVE GRYON AETHERIUM TALAMAS (HYMENOPTERA, SCELIONIDAE) ASSOCIATED WITH EGGS OF BAGRADA HILARIS (BURMEISTER) (HEMIPTERA, PENTATOMIDAE) IN THE USA

Adventive Gryon aetherium Talamas (Hymenoptera, Scelionidae) associated with eggs of Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae) in the USA

Bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera, Pentatomidae), has become a major pest of cole crops (cabbage, broccoli, cauliflower, kale) in California since its arrival in 2008.In this study we documented parasitism of B.hilaris eggs at a highly infested site in northern California by deploying sentinel B.hilaris eggs and collecting natura

Traumatic auricular hematoma

Auricular hematoma is a frequent complication of blunt trauma to the auricle.These are usually caused by sports such as boxing and wrestling.Hematoma formation is within the space between perichondrium and cartilage on the anterior ear.Because the blood supply to cartilage is dependent on the perichondrium, infection and cartilaginous necrosis ofte

On nonlinear dynamics and control of a robotic arm with chaos

In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic gotrax handlebar connector.In the mathematical model, a chaotic motion was identified, for a wide range of parameters.Controlling of the chaotic behaviour of the system, were implemented using, two control
