The snake transversus abdominis muscle is an extremely simple segmentally repeating muscle containing 80 to 100 muscle fibers in a single-fiber-thick sheet. This muscle exhibits a striking pattern of muscle fiber types: twitch fibers alternate with tonic fibers and, among the twitch fibers, slower and faster contracting subtypes also alternate. Thus, in many regions of the muscle the pattern of...

Several incidence theorems of planar projective geometry are considered. It is demonstrated that generalizations of Pascal theorem due to Möbius give rise to double cross-ratio equation and Hietarinta equation. The construction corresponding to the double cross-ratio equation is a reduction to a conic section of some planar configuration (203154). This configuration provides a correct definitio...

Considering the vulnerability of double-layer grid space structures to progressive collapse phenomenon, it is necessary to pay special attention to this phenomenon in the design process. Alternate path method is one of the most appropriate and accepted methods for progressive collapse resistant design of structures. Alternate Path Method permits local failure to occur but provides alternate pat...

In diesem Beitrag wird ein Programm zur effektiven Sicherheitssensibilisierung im Unternehmen entwickelt. Schwerpunkte des Programms liegen auf Bedrohungsszenarien, der Form eines ‚Alternate Reality Game‘ zur Wissensvermittlung und messbaren Erfolgsgrößen. Mithilfe des Programms soll eine dauerhafte Verhaltensänderung erreicht werden.

Let f : V (G) → {1, 2,..., |V (G)|} be a bijection, and let us denote S = f(u) + f(v) D |f(u) − f(v)| for every edge uv in E(G). f' the induced labeling, by vertex labeling f, defined as E(G) {0, 1} such that any E(G), (uv)=1 if gcd(S, D)=1, (uv)=0 otherwise. ef' (0) (1) number of edges labeled with 0 1 respectively. is SD-prime cordial |ef' (1)| ≤ G graph it admits labeling. In this paper, we ...

Since time immemorial the snake has been venerated as an enigmatic creature with supernatural powers. As a snake and staff symbol it is also traditionally associated with the healing arts, either as the single-snake emblem of Asklepios, or as the double-snake emblem (caduceus) of Hermes. The mythological basis for this symbolism is reviewed. The Asklepian emblem has been associated with health ...

Our paper has two goals: i) We propose the combinatorial approach to facilitate the calculation of the number of spanning trees for five new classes of graphs. ii) We use a new powerful operation (subdivision) to get larger graphs from a given graph. In particular, we derive the explicit formulas for the subdivision of ladder, fan, triangular snake, double triangular snake and the total graph o...

This paper presents the concept of muscle-driven locomotion for planar snake robots, which combines advantages both rigid and soft robotic approaches to enhance performance robot locomotion. For this purpose, two adjacent links are connected by a pair pneumatic artificial muscles wherein an alternate actuation these actuators causes rotational motion at connecting joints. The muscle-based actua...
