This article analyzed decision-making in terms of the adoption of public cloud computing and its determinants in the context of e-government. The authors proposed a theoretical model and related hypotheses after reviewing the literature and combining technology adoption theory with IT decisionmaking authority theory. Then, they collected samples from 227 public sectors and tested hypotheses usi...

Spectrophotometric-dual-enzyme-simultaneous-assay (SDESA) for enzyme-linked-immunosorbent-assay (ELISA) of two components in one well is a patented platform when a special pair of labels is accessible. With microplate readers, alkaline phosphatase on 4-nitro-1-naphthylphosphate (4NNPP) served as label A; Pseudomonas aeruginosa arylsulfatase (PAAS) and acetylcholinesterase (AChE) on their substr...

Cloud technology is evolving at a rapid pace with innovation occurring throughout the software stack. While updates to Software-as-a-Service (SaaS) products require a simple push of code to the production servers or platform, updates to the Infrastructure-as-a-Service (IaaS) or Platform-as-a-Service (PaaS) layers require more intricate procedures to prevent disruption to services at higher abst...

In this paper, we describe Roots – a system for automatically identifying the “root cause” of performance anomalies in web applications deployed in Platform-as-a-Service (PaaS) clouds. Roots does not require application-level instrumentation. Instead, it tracks events within the PaaS cloud that are triggered by application requests using a combination of metadata injection and platform-level in...

ABSTRACT The study aims to show the evolution of percentage schools adhering School Health Program (PSE) that carried out a collective activity on Promotion Adequate and Healthy Eating (PAAS) over last five years verify if there is difference in this indicator according adhesion Growth (PCS). Ecological study, developed with data registered Information System for Primary Care (SISAB). performan...

We present the design and implementation of AppScale, an open source extension to the Google AppEngine (GAE) Platform-asa-Service (PaaS) cloud technology. Our extensions build upon the GAE SDK to facilitate distributed execution of GAE applications over virtualized cluster resources, including Infrastructure-as-a-Service (IaaS) cloud systems such as Amazon’s AWS/EC2 and Eucalyptus. AppScale pro...

This work reports the development of new non-thrombogenic polymers based on the linear polymers of polyamidoamines (PAAs), having heparin binding ability, obtained by polyaddition of secondary amines to N,N'-methylene bis-acrylamide. PAAs could not be used directly in the making of blood-contacting materials due to their poor mechanical strength. In order to overcome this lacuna, copolymers of ...

The 4CaaSt project aims at developing a PaaS framework that enables flexible definition, marketing, deployment and management of Cloud-based services and applications. This paper describes the major challenges tackled by 4CaaSt for the comprehensive management of applications and services in a PaaS. These challenges involve the blueprint language to describe applications in the cloud and its li...

In this work, the dispersive effect of low molecular weight sodium polyacrylate (PAAS) on serpentine, and its dispersion mechanism were systematically investigated through zeta potential measurements, micro and batch flotation as well as adsorption tests. At pH 5, where flotation of iron sulphide was routinely performed, pyrite and serpentine minerals were oppositely charged, and therefore they...

Cloud Platform as a Service (PaaS) is a novel, rapidly growing segment in the Cloud computing market. However, the diversity and heterogeneity of today’s existing PaaS offerings raises several interoperability challenges. This introduces adoption barriers due to the lock-in issues that prevent the portability of data and applications from one PaaS to another, “locking” software developers to th...
