A new generalized model for predicting the density of single- and mixed-electrolyte solutions
No full textA new generalized method is proposed for predicting the density of single- and mixed-electrolyte solutions at 298.15 K from osmotic pressure and ionic radii. In this treatment, the electrolyte solution was modeled as a mixture of ionic hard sphere and compressible water situated in the field of an external pressure, i.e., osmotic pressure. The molar volume of the solution is considered to be the sum of both intrinsic volume of ions and apparent molar volume of water. The former is estimated from the method suggested by Conway et ai. [B.E. Conway, J.E. Desnoyers, C. Smith, Philos. Trans. R. Sec. London, Ser. A 256 (1989) 389-392], and the latter directly from the osmotic pressure. The applicability of the model was tested with 138 single- and 15 binary-electrolyte solutions. The overall average absolute relative deviations (AAD) were found to be 2.38% and 1.13% for the single-electrolyte solutions and 2.80% and 0.96% for the binary-electrolyte solutions when the Pauling radii and the maximum Shannon radii were used for the ionic radii in solutions. On the other hand, in cases where the ionic radii in solutions were treated as the ion-specific parameters that can be applied to all types of salts, the AAD were greatly improved to 0.88% for the 138 single-electrolyte solutions and 0.65% for the 15 binary-electrolyte solutions.

An investigation into the factors that influence the intention to use E-commerce : the Jordanian business-to-business market
No full textSeveral researchers have suggested that behavioural decision theories from the field ofsocial psychology could provide a potential foundation for research on user behaviour.Generally, the majority of research in information technology adoption have utilisedone of four of the well-established theories (diffusion of innovation, theory of reasonedaction, theory of planned behaviour and technology acceptance model). Mostly thesetheories have proposed to measure attitudes toward behaviour and identify the role ofthese attitudes in shaping behaviours. Gaps in the previous theories were identified anda preliminary study was conducted to generate a better understanding of the status ofbusiness to business (B2B) e-commerce usage within Jordanian companies. Theliterature review led to the development of a conceptual model proposing severalfactors such as trusting information technology, security, legal issues, company size,cost, education infrastructure, foreign language skills and top management support,which could impact on the intention to use B2B e-commerce in Jordan. Therefore, thisstudy aimed to investigate and identify the major factors that affect the intention to useB2B e-commerce in Jordan.Following the development of the conceptual model, a research survey was developedand conducted to investigate the intention to use B2B e-commerce among Jordaniancompanies. The hypotheses that were derived from the conceptual model wereexamined through statistical analysis using factor analysis, Mann-Whitney U Test,Kruskal-Wallis Test, multiple and hierarchical regressions. The findings of this studysuggested that there are three main factors that tend to affect firms' intentions to useB2B e-commerce: trusting information technology and security, top managementexperience, perceived ease of use and perceived usefulness. This study has a number oftheoretical and practical implications. It contributes to the state of knowledge in ecommerceadoption in developing countries and contributes to filling the previouslyidentified gaps in the literature on B2B e-commerce adoption by being the initial studyto deal with the intention of Jordanian companies to adopt e-commerce. The findings ofthis study are important and relevant to Jordanian and international companies and thegeneral and IT managers of these companies. Based on the findings of the study, a setof strategies were recommended which could be potentially used to enhance B2B ecommerceadoption in Jordan

IgG antibody responses to Plasmodium falciparum merozoite antigens in Kenyan children have a short half-life.
No full textBACKGROUND: Data suggest that antibody responses to malaria parasites merozoite antigens are generally short-lived and this has implications for serological studies and malaria vaccine designs. However, precise data on the kinetics of these responses is lacking. METHODS: IgG1 and IgG3 responses to five recombinant Plasmodium falciparum merozoite antigens (MSP-119, MSP-2 type A and B, AMA-1 ectodomain and EBA-175 region II) among Kenyan children were monitored using ELISA for 12 weeks after an acute episode of malaria and their half-lives estimated using an exponential decay model. RESULTS: The responses peaked mainly at week 1 and then decayed rapidly to very low levels within 6 weeks. Estimation of the half-lives of 40 IgG1 responses yielded a mean half-life of 9.8 days (95% CI: 7.6-12.0) while for 16 IgG3 responses it was 6.1 days (95% CI: 3.7-8.4), periods that are shorter than those normally described for the catabolic half-life of these antibody subclasses. CONCLUSION: This study indicates antibodies against merozoite antigens have very short half-lives and this has to be taken into account when designing serological studies and vaccines based on the antigens
3D pgRouting and visualization in Cesium JS using the integrated model of LADM and IndoorGML
No full textA web-based application has been developed, exploiting the integrated model of LADM andIndoorGML to provide indoor navigation based on the user's access rights in an educationalbuilding. Different types of users (students, teachers, visitors, etc.) have different access rights,which also depend on the exact time (e.g. inside or outside office hours). A 3D BIM IFC fileof a building has been geo-referenced and converted into a LADM complaint database inPostgreSQL/PostGIS and is enriched with information about access rights based on therelationship between users, time and indoor spaces. The PostgreSQL extension pgRouting hasbeen used for the actual routing. To support the access rights-based routing, the databasecontains several tables to represent nodes, edges, parties (users), and rights. There is one overallnetwork for the whole building, and database views are used to dynamically select the relevantnodes and edges based on the time and the user’s rights. The Dijkstra algorithm is used tocompute the shortest path. Finally, the 3D geospatial web-platform Cesium JS is used to createa client GUI allowing to specify start and destination, the user and time, and to visualize thenavigation routes. As this GUI is web-based it can run on different platforms, such as desktops,laptops, tablets and mobile phones. This paper provides a complete description of all the stepsto design, develop and test the integrated model of LADM and IndoorGML.GIS Technologi

Eddy-Induced Growth Rate of Low-Frequency Variability and Its Mid- to Late Winter Suppression in the Northern Hemisphere
No full textSynoptic eddy and low-frequency flow (SELF) feedback plays an important role in reinforcing low-frequency variability (LFV). Recent studies showed that an eddy-induced growth (EIG) or instability makes a fundamental contribution to the maintenance of LFV. To quantify the efficiency of the SELF feedback, this study examines the spatiotemporal features of the empirical diagnostics of EIG and its associations with LFV. The results show that, in terms of eddy vorticity forcing, the EIG rate of LFV is generally larger (smaller) in the upper (lower) troposphere, whereas, in terms of eddy potential vorticity forcing, it is larger in the lower troposphere to partly balance the damping effect of surface friction. The local EIG rate shows a horizontal spatial distribution that corresponds to storm-track activity, which tends to be responsible for maintaining LFV amplitudes and patterns as well as sustaining eddy-driven jets. In fact, the EIG rate has a well-defined seasonality, being generally larger in cold seasons and smaller in the warmest season, and this seasonality is stronger in the Northern Hemisphere than in the Southern Hemisphere. This study also reveals a mid-to late winter (January-March) suppression of the EIG rate in the Northern Hemisphere, which indicates a reduced eddy feedback efficiency and may be largely attributed to the eddy kinetic energy suppression and the midlatitude zonal wind maximum in the midwinter of the Northern Hemisphere.O (subject to Restrictions below, author can archive publisher's version/PDF)1144sciescopu
Frozen Corpses and Feuding Parents: Re JS (Disposal of Body)
No full textIn October 2016, a dying teenager won the legal right to have her remains cryogenically frozen and stored indefinitely in an American clinic. The cryonics aspect was novel, posing questions around the legality of this particular method of corpse ‘disposal’ in the UK and the processes involved. More significantly, the case raises other substantive legal issues around the fate of the dead, including the status of funeral instructions under English law, and how courts adjudicate parental disputes over the funeral arrangements for a dead child
