In order to preparing strontium ion selective electrode 6-(4- nitropheny1)-2-pheny14, 4- dipropy1-3, 5-diaza-bicyclo [3, 1, 0] hex-2-ene (NPDBH) was used as an ionophore. This electrode responds to Sr (II)ion with a sensitivity of 28.2 ± 0.5 mV/decade over the range 1.0 x 10-6 to 1.0 Mat pH 3.0-10.0. Thelimit of detection was 2.4 x 10-7 M. The influences of membrane composition, the pH of the t...

ion has been found not to occur in the D + H20 reaction.22 Recently, the back reaction OH+D2 -HOD +D has been studied,12 and the HOD product shows pronounced back scattering, which is consistent with the proposed transition-state geometry. In addition to these investigations, two groups have reported experimental studies of the effect of vibrational excitation on the abstraction reaction. Crim ...

Our goals were to quantify how non-embolisminducing pressure gradients influence trunk sapwood specific conductivity (ks) and to compare the impacts of constant and varying pressure gradients on ks with KCl and H20 as the perfusion solutions. We studied six woody species (three c~nifers and three angiosperms) which varied in pit membrane struc. ture, pit size and frequency of axial water transp...

The system CaO-MgO-SiO2-CO2-H20 is an important model for many igneous and metamorphic processes, including the generation and differentiation of carbonatite and associated silicate magmas. We have experimentally established the vapor-saturated solidus for the system CaO-MgO-CO2-H20 from 595øC/1 kbar to <500øC/40 kbar, about 25øC lower than the corresponding temperatures for the CaOCO•-H•O syst...

ProSeal Laryngeal mask airway is increasingly being used as an airway device for laparoscopic surgery. Nitrous oxide can diffuse into the cuff of airway devices and may further increase the intracuff pressure. The present study was designed to investigate the intracufff pressure changes during anesthesia with and without use of nitrous oxide in patients undergoing laparoscopic surgery and also ...

BACKGROUND Nasal strips are used by athletes, people who snore, and asthmatics to ease the burden of breathing. Although there are some published studies that demonstrate higher flow with nasal strips, none had directly measured the effect of the strips on nasal resistance using the airflow perturbation device (APD). The APD is an inexpensive instrument that can measure respiratory resistance b...

A nest of long terminal repeat (LTR) retrotransposons (RTRs), discovered by LTR_STRUC analysis, is near core genes encoding the NPR1 disease resistance-activating factor and a heat-shock-factor-(HSF-) like protein in sugarbeet hybrid US H20. SCHULTE, a 10 833 bp LTR retrotransposon, with 1372 bp LTRs that are 0.7% divergent, has two ORFs with unexpected introns but encoding a reverse transcript...

Soja (Glycine max. (L.) Merr.) je jedna od najznačajnijih uljarica koja našla široku primjenu u ishrani ljudi, proizvodnji hrane za stoku te obogaćivanju tla dušikom. Obzirom na sve učestaliju pojavu klimatskih ekstrema, izostanak oborina ili nepravilan raspored tijekom razdoblja vegetacije nadprosječno visoke temperature zraka, zabilježeno sniženje prinosa soje uslijed jednog najvažnijih abiot...

Automated Machine Learning (AutoML) frameworks are designed to select the optimal combination of operators and hyperparameters. Classical AutoML-based Bayesian Optimization (BO) approaches often integrate all operator search spaces into a single space. However, disadvantage this history-based strategy is that it can be less robust when initialized randomly than optimizing each algorithm indepen...
