Background: The snake, Echis carinatus, one of the most venomous snakes in Asia, possesses a deadly hemotoxic venom. It has been reported that suramin, an anti-trypansomiasis drug, can inhibit the toxic effects of some snake venoms. This study was conducted to evaluate the possible antagonistic effects of suramin against the hemorrhagic activity of the venom from an Iranian snake, Echis carinat...

we show that when both sources ( lepton flavor violation sources and cp-violating phases) are present, the electric dipole moment of the electron, $d_e$, receives a contribution from the phase of the trilinear $a$-term of staus, $phi_{a_ au}$. for $phi_{a_ au}=pi/2$, the value of $d_e$, depending on the ratios of the lfv mass elements, can range between zero and three orders of magnitude a...

Amphibious snake-like robots are advantageous than traditional snake-like robots for their adaptability in aquatic environments. This paper presents a novel amphibious snake-like robot. The mechanism and control system of the robot are illustrated. A simplified Serpenoid Curve is used to generate the basic undulation of the robot. Three-dimensional gaits are generated by combining undulations o...

Snake-like robots have been widely studied due to their special 3D locomotion ability and the adaptability in diverse complex environments. Autonomous locomotion, that is, acquiring environment information, making locomotion decisions independently and then performing locomotion, is of the essence for snake-like robots to complete self-governed tasks in various complex terrain. The traditional ...

Recently, several generalizations of the notion of orthogonal polynomials appeared in the literature. The aim of this paper is to study their zeros. Let P k be the unique polynomial of exact degree k such that Z b a x i P k (x) dd(x) = 0; for i = 0; : : : ; k ? 1 where is a positive Borel measure on a; b]. P k is the polynomial of degree k belonging to the family of orthogonal polynomials on a;...

Snake robots have been a topic of discussion among researchers for decades. They are potentially strong enough to bring substantial contributions the fields which unsafe/ narrow/ dirty/ hard reachable human operators, such as inspections, rescue missions, firefighting, etc. Though inventions wheel and legged mechanisms amazing, they often fail when coming these scenarios. Terrain adaptability i...

Taloo and Shirband hunting Prohibited area is located 12 kilometers North-East of Damghan in Semnan Province, south of the Alborz Mountain Chains. It has a cold and dry climate in the winter and warm and dry in the summer. This area has a rich biodiversity, especially in its reptilian fauna. 22 snake species were reported so far from Semnan Province. However, no comprehensice study was executed...
