The article is dedicated to the complex stage in fate of Theodore Roosevelt, his life «Badlands» North Dakota, where he first appeared September 1883 hunt bison. Literally, we can say at glance fell love with these places. Fascinated by Roosevelt decided invest 14 thousand dollars purchase Chimney Butte Ranch, later renamed Maltese Cross Ranch. turned management lands over Sylwane Ferris and Bi...

We have examined each group of annual Nobel Prize winners since 1979. Beginning with the 1982 awards, I we included data from the research fronts we identify each year for Science Citation Index” (SCP’ ). Briefly, a research front is a group of current papers that cite a cluster of “core” papers identified by co-citation clustering. These procedures have been described previously.2 By systemati...

Platinum group metals (PGMs) play a key role in modern society as they find application clean technologies and other high-tech equipment. Spent catalytic converters secondary resource contain higher PGM concentrations the recovery of these via leaching is continuously being improved but efforts are also directed at purification individual metal ions. The study presents PGMs, namely, rhodium (Rh...

In 1995 Gebeck & Merrifield studied a successful and unsuccessful treated Class I II’s samples; they found -1.33 mm intrusion in the former 0.80 extrusion latter. The purpose of this article was to perform cephalometric evaluation maxillary incisors torque vertical changes. We sample 129 patients, 30 males 99 females, taken from Charles H. Tweed Foundation Long Term Study, at pretreatment mea...

In the goby, Gillichthys mirabilis, urotensin II (a bioactive neuropeptide present in the urophysis of teleost fish) has the dodecapeptide sequence, H2N-AGTADC-FWKYCV-OH, which is homologous with mammalian somatostatin at positions 1, 2 and 7-9. The Merrifield solid phase synthesis of Gillichthys urotensin II (UII) was accomplished by stepwise assembly from the carboxy terminus using N-alpha-te...

We report two asymmetric ligands for the generation of structural and functional dinuclear metal complexes as phosphoesterase mimics. Two zinc(II) complexes, [Zn2(CH3L4)(CH3CO2)2](+) (CH3HL4 = 2-(((2-methoxyethyl)(pyridin-2-ylmethyl)amino)methyl)-4-methyl-6-(((pyridin-2-ylmethyl)amino)methyl)phenol) and [Zn2(CH3L5)(CH3CO2)2](+) (CH3HL5 = 2-(((2-methoxyethyl)(pyridine-2-ylmethyl)amino)methyl)-4-...

Abstract. The energy of a molecular graph is a popular parameter that is defined as the sum of the absolute values of a graph’s eigenvalues. It is well known that the energy is related to the matching polynomial and thus also to the Hosoya index via a certain Coulson integral. Trees minimizing the energy under various additional conditions have been determined in the past, e.g., trees with a gi...
