Potentiometric analysis of sea water II. Determination of titration alkalinity

Sea water is alkaline mainly due to the presence of appreciable quantities of carbonate, bicarbonate and borate ions. These react with the H+ from the ionization of water leaving an excess of OH\u27 present…

Potentiometric analysis of sea water I. Determination of chlorinity

In general the determination of chlorinity of sea water is made by the classical Mohr method except when greater accuracy is desired in which case the more accurate but longer Volhard method is used. When the results are utilized for hydrodynamical considerations the Mohr method is normally used because of its speed in the titration of the numerous samples; but to attain the accuracy required in this exacting work, extreme care is demanded with the shaking during titration and in the proper selection of end point

Performance management of National Sports Organisations: a holistic theoretical model

Purpose Organisational performance of sport organisations has been studied over the last three decades. However, little attention was paid towards performance management (PM) compared to performance measurement. The purpose of this paper is to close this research gap by establishing a holistic perspective for PM of National Sports Organisations (NSOs) that accounts for their uniqueness, the interdependence of their operating systems and their relationship with their environments. Furthermore, this paper presents a holistic model of PM for NSOs. Design/methodology/approach The model was developed from a literature review process and uses the macro, meso and micro framework to describe external and internal environmental influences that affect the PM of NSOs. Findings The NSO’s ability to respond to the dynamics of their external environment by implementing organisational processes that account for the resources available and their structural designs influences their PM. Furthermore, the ability of the individuals within NSO to create enabling environments for PM influences organisational efficiency and effectiveness. Research limitations/implications This paper contributes to sport management literature on the PM of NSOs, and informs sport managers on ways to improve organisational performance by implementing holistic approaches to PM. Originality/value This is the first study that takes a holistic approach to PM of NSO and depicts the specific elements that play a crucial role in managing NSO’s multi-dimensional performance

Noise effects on One-Pauli Channels

The possibility of stochastic resonance of a quantum channel and hence the noise enhanced quantum channel capacity is explored by considering one-Pauli channels which are more classical like. The fidelity of the channel is also considered

Genome sequences of 15 Gardnerella vaginalis strains isolated from the vaginas of women with and without bacterial vaginosis

Gardnerella vaginalis is a predominant species in bacterial vaginosis, a dysbiosis of the vagina that is associated with adverse health outcomes, including preterm birth. Here, we present the draft genome sequences of 15 Gardnerella vaginalis strains (now available through BEI Resources) isolated from women with and without bacterial vaginosis

Structural Analysis in a Conceptual Design Framework

Supersonic aircraft designers must shape the outer mold line of the aircraft to improve multiple objectives, such as mission performance, cruise efficiency, and sonic-boom signatures. Conceptual designers have demonstrated an ability to assess these objectives for a large number of candidate designs. Other critical objectives and constraints, such as weight, fuel volume, aeroelastic effects, and structural soundness, are more difficult to address during the conceptual design process. The present research adds both static structural analysis and sizing to an existing conceptual design framework. The ultimate goal is to include structural analysis in the multidisciplinary optimization of a supersonic aircraft. Progress towards that goal is discussed and demonstrated

Withering the citizen, managing the consumer: complaints in healthcare settings

This paper considers concepts of citizenship and consumerism in light of complaints about healthcare, which have risen since the early1990s, due to a greater willingness by the healthcare user to complain, and also the reforms in complaint systems. The narrow legal model for dealing with complaints has been replaced by a managerial model based on corporate sector practice that views complaint handling as a way of retaining customers and organisational learning. The managerial model has proved difficult to embed into the English NHS and has been superposed with a centralised regulatory system that aims to manage performance while also being responsible for reviewing, complaints and being responsive to complainants. It is argued that this may have positive consequences in terms of improving healthcare quality but more negatively, the promotion of consumerism within complaints processes has led to a loss of the right to due process and public accountability
