Treatment of P4 with in situ generated [Na][SnPh3] leads to the formation of the sodium monophosphide [Na][P(SnPh3)2] and the Zintl salt [Na]3[P7]. The former was isolated in 46% yield as the crystalline salt [Na(benzo-15-crown-5)][P(SnPh3)2] and used to prepare the homoleptic phosphine P(SnPh3)3, isolated in 67% yield, as well as the indium derivative (XL)2InP(SnPh3)2 (XL = S(CH2)2NMe2), isola...

Increasingly users are seen as the weak link in the chain, when it comes to the security of corporate information. Should the users of computer systems act in any inappropriate or insecure manner, then they may put their employers in danger of financial losses, information degradation or litigation, and themselves in danger of dismissal or prosecution. This is a particularly important concern f...

Melt electrowriting (MEW) is an additive manufacturing process that produces highly defined constructs with elements in the micrometer range. A specific configuration of MEW enables printing tubular to create small-diameter structures. The small pool processable materials poses a bottleneck for wider application biomedicine. To alleviate this obstacle, acrylate-endcapped urethane-based polymer ...

Cefiderocol, a novel parenteral siderophore cephalosporin, exhibits potent efficacy against most Gram-negative bacteria, including carbapenem-resistant strains. The aim of this study was to perform a population pharmacokinetic (PK) analysis based on plasma cefiderocol concentrations in healthy subjects, subjects with various degrees of renal function, and patients with complicated urinary tract...

RESUMO O artigo consiste em uma revisão sistemática da literatura sobre a multifuncionalidade agricultura urbana e periurbana realizada nas bases de dados Science Direct (Elsevier), Scientific Electronic Library (Scielo) Portal Periódicos Capes, utilizando os descritores: “agricultura urbana” AND “multifuncionalidade”, “multifuncional”, “urban agriculture” “multifunctionality”, “multifunctional...

Although databases focus on the longevity of data, rarely is this data or its structure static. This is particularly true in some domains such as the protein databases that have seen and continue to see an exponential growth rate. Managing the effects of change on derived information (views, web pages) and on applications has been recognized as an important problem. Previous research efforts ha...

In the paper, parameters of 115 types existing wind turbines (WT) were analyzed and their power curves modeled by using Weibull cumulative distribution function (CDF). On basis these data, regression equations obtained for CDF WT due to main sizes: nameplate capacity generator P rotor D. Based on analysis sizes, model average used (AUP) in specific conditions has been built. The area existence ...
