The major aim of the present study was to investigate element (Fe, Ni, Pb, V, Zn) concentrations in sediment and different tissues of Phragmities australis and Typha latifolia in Hor al-Azim Wetland Southwest Iran. Sampling of sediments and aquatic plants was carried out during spring and summer 2014. Results showed that the mean  concentrations of elements in Phragmities ...

In the mononuclear title complex, [Ni(C(14)H(19)N(2)O(3))(NCS)], the nickel(II) atom is four-coordinated in a square-planar geometry by the O and N atoms of the tridentate Schiff base ligand and by the N atom of a thio-cyanate ligand. The crystal structure is stabilized by inter-molecular C-H⋯S and C-H⋯O hydrogen bonds, forming a three-dimensional network.

RESUMO Uma doença ou condição de saúde pode ser entendida enquanto um estímulo que produz uma Necessidade Informação (NI). Cada vez mais, indivíduos recorrem a comunidades on-line para solucionar suas dúvidas sobre sua situação saúde. A pandemia da Covid-19 configurou-se como evento singular produção NI. Nesse contexto, o objetivo do estudo foi identificar as NI em comunidade organizada no Face...

We discuss the kinetics of a disoriented chiral condensate, treated as an open quantum system. We suggest that the problem is analogous to that of a damped harmonic oscillator. Master equations are used to establish a hierarchy of relevant time scales. Some phenomenological consequences are briefly outlined.

Activation energies for the intermixing reaction of textured metal-metal multilayer thin films have been determined using x-ray diffraction analysis. Kinetic data were collected utilizing an area detector so as to reduce intensity bias from changes in out-of-plane texture during the intermixing reaction. Activation energies for Al/Pt, Ni/Ti, and Co/Al metal-metal multilayer thin films have been...

Hydrogenase [hydrogenase: (acceptor) oxidoreductase, EC 1.12. . -1 is present in many bacteria. It is one of the enzymes having potential use in the biophotolysis of water (Weaver et al.. 1980). When we began our research on hydrogenase in 1977, two types of enzymes were known: (i) enzymes containing 12 Fe atoms and an equivalent amount of acid-labile S atoms and (ii) enzymes containing only fo...

OBJECTIVE The aims of the study are to assess the marginal accuracy of base metal and titanium alloy casting and to evaluate the effect of repeated ceramic firing on the marginal accuracy of base metal and titanium alloy castings. MATERIALS AND METHODS Twenty metal copings were fabricated with each casting material. Specimens were divided into 4 groups of 10 each representing base metal alloy...

CU-acquired nosocomial infection (NI) remains one of the major causes of ICU mortality. This study presents the incidence of ICU-acquired nosocomial infection in ICU HUKM for the years 1998 and 1999, as part of the ongoing ICU-acquired nosocomial infection surveillance program. The overall incidence was 23%. The main types of NI was lower respiratory tract infection (15.3%), primary bacteraemia...
