Two simple and sensitive indirect spectrophotometric methods for the assay of propranolol hydrochloride (PPH) and piroxicam (PX) in pure and pharmaceutical formulations have been proposed. The methods are based on the oxidation of PPH by a known excess of standard N-bromosuccinimide (NBS) and PX by ceric ammonium sulfate (CAS) in an acidic medium followed by the reaction of excess oxidant with ...

A CE instrument coupled with chemiluminescence (CL) detection was designed for the determination of promethazine hydrochloride (PTH) and promazine hydrochloride (PMH) in real samples. An important enhancement of the CL emission of luminol with potassium ferricyanide was observed in the presence of these phenothiazines; so this system was selected for their detection after CE separation. Paramet...

Personal mobile healthcare (PMH) services based on Internet-of-Things (IoT) have big potentials in business. To catch this opportunity, an ecosystem should be established first. Technical architectures should aim for a cooperative ecosystem by addressing the interoperability, security, and system integration. In this paper, we propose an ecosystem-driven design strategy and apply it in the desi...

Pure motor hemiplegia (PMH) is a well defined syndrome usually caused by ischemic lesions of lacunar type located either in the internal capsule or in the pons. Angiography and isotope scanning are usually normal. CT scan reveals small deep infarcts and appears to be the most reliable investigative method. The CT scan findings are described of thirty patients with PMH of rapid onset (less than ...

Particle Metropolis-Hastings (PMH) allows for Bayesian parameter inference in nonlinear state space models by combining MCMC and particle filtering. The latter is used to estimate the intractable likelihood. In its original formulation, PMH makes use of a marginal MCMC proposal for the parameters, typically a Gaussian random walk. However, this can lead to a poor exploration of the parameter sp...

BackgroundEpidemiological data on neonatal bloodstream infections (BSI) in sub-Saharan Africa are extremely limited.MethodsA comparative analysis of laboratory-confirmed BSI episodes was conducted retrospectively two large units Botswana and South (January 1 to December 31, 2017). Routine laboratory ward register were used determine rates, the pathogen spectrum, outcomes.ResultsIn 2017, Princes...

In order to establish the relationship between academic self-perception of university professors according their gender, which takes into account internal and external factors, such as technostress, PMH scale (unidimensional Positive Mental Health Scale) factors that are related an organization, is understood be a university, climate commitment professor, constructs were used in our research. T...

The proliferation of the Open Archive Initiative Protocol for Metadata Harvesting (OAI-PMH) has resulted in the creation of a large number of service providers, all harvesting from either data providers or aggregators. If data were available regarding the similarity of metadata records, service providers could track redundant records across harvests from multiple sources as well as provide addi...

In this paper, we introduce the Enhanced Kepler Framework, an evolution of the original Kepler framework which implements an OAI-PMH-compliant data provider for individual publishers. The enhanced Kepler framework is heavily influenced by Fasttrack, a peer-to-peer network. In particular, we introduce the concept of buddy nodes and SuperNodes to improve scalability. We also propose enhancements ...
