Stable palladium nanoparticles were prepared by the passivation of palladium–carbon covalent linkages by the reduction of diazonium derivatives. The resulting particles were characterized by TEM, UV-vis, FTIR, and NMR measurements. Interestingly, in electrochemical studies of the electronic conductivity of the particle solid ensembles, Pd–biphenyl particles exhibited metallic temperature depend...

The antitumor activity of a novel ansamycin antibiotic, trienomycin A, against various murine tumors was studied with two treatment schedules. The intraperitoneal injection of the antibiotic showed remarkable antitumor activity on sarcoma 180 and P388 leukemia at doses of 160 or 320 mg/kg, showing 151% and 100% increase in life span, respectively. Trienomycin A inhibited the growth of Ehrlich a...

There have been several attempts to account for the impact of Mathematical Anxiety (MA) on brain activity with variable results. The present study examines the effects of MA on ERP amplitude during performance of simple arithmetic calculations and working memory tasks. Data were obtained from 32 university students as they solved four types of arithmetic problems (one- and two-digit addition an...

Abstract Fly ash represents a promising alternative source of rare earth elements (REE). However, information on REE containing mineral phases and their association with other fly components, vital for recovery from ash, is currently lacking. Herein, the mass fraction, distribution, crystallography solid-state chemistry REE, U Th in Nigerian simulated samples were characterised using range labo...

We performed a molecular genetic study on the sequences of 18S ribosomal RNA (ITS1 region) gene in 4-day-old adult worms of Macroorchis spinulosus recovered in mice experimentally infected with metacercariae from crayfish in Jeollanam-do Province, Korea. The metacercariae were round, 180 μm in average diameter, encysted with 2 layers of thick walls, but the stylet on the oral sucker was not cle...

Event-related brain potentials were used to investigate the shortcut calculation strategy and nonshortcut calculation strategy in performing addition using mental arithmetic. Results showed that the shortcut calculation strategy elicited a larger P220 than the nonshortcut calculation strategy in the 180-280 ms. Dipole source analysis of the difference wave (shortcut calculation minus nonshortcu...

The relationship between conflict resolution strategies and organizational citizenship behavior (OCB) and the moderating role of trait Emotional Intelligence (EI) were investigated. Participants were 320 public servants (male = 180, female = 140) randomly selected from 5 states in southwestern Nigeria. Measures of trait EI, OCB, and conflict resolution strategies were administered to the respon...
