the mathematical properties of nano molecules are an interesting branch of nanoscience forresearches nowadays. the periodic open single wall tubulene is one of the nano moleculeswhich is built up from two caps and a distancing nanotube/neck. we discuss how toautomatically construct the graph of this molecule and plot the graph by spring layoutalgorithm in graphviz and netwrokx packages. the sim...

669 Myofunctional Therapy for OSA—Camacho et al. INTRODUCTION Several medical and surgical treatment modalities exist as treatment for obstructive sleep apnea (OSA).1–3 Four pathophysiological traits seen in patients with OSA are: the passive critical closing pressure of the upper airway (Pcrit), arousal threshold, loop gain, and muscle responsiveness (PALM) with categories of 1, 2, 2a, 2b, and...

wiener index is a topological index based on distance between every pair of vertices in agraph g. it was introduced in 1947 by one of the pioneer of this area e.g, harold wiener. inthe present paper, by using a new method introduced by klavžar we compute the wiener andszeged indices of some nanostar dendrimers.

provided the original work is properly cited. CC Gastric bypass surgery is recognized as the most effective treatment for severely obese patients who cannot effectively control their weight through diet and exercise. During gastric bypass surgery, proper anesthetic management requires special attention from preoperative assessment to postoperative recovery, especially for airway management. We ...

in this paper pi, szeged and revised szeged indices of an infinite family of ipr fullereneswith exactly 60+12n carbon atoms are computed. a gap program is also presented that isuseful for our calculations.
