Nowadays, complex electronic products, such as DVD players or mobile phones, offer a huge number of functions. As a consequence of the complexity of the devices, customers often have problems to use such products effectively. For example, it has been observed that an increasing number of technically sound products is returned due to, e.g., interaction problems. One possible root cause of this p...

Recent information systems (IS) publications reveal an emerging interest in studying postadoptive system use behaviors. Compared to the well-established research stream of IS adoption and initial usage, understanding of IS use behaviors after initial implementation stage is still at its early stage. To further develop knowledge about this phenomenon, this study reviews the IS implementation sta...

Information systems (IS) research has focused extensively on the factors that foster adoption and usage. A large body of work explores overall beliefs about system usage, antecedents of system satisfaction, and other perceptions that enable system success, create positive attitudes, and encourage usage. However, much less attention has been given to what perceptions uniquely inhibit usage. In l...

the effect of short term usage of gnrh antagonist as pretreatment on superovulation in goats was evaluated. statistical analysis was performed using t-test and showed that usage of gnrh antagonist as pretreatment can improve number of recovered embryos (p0.05). this study showed that usage of gnrh antagonist can improve superovulatory response in term of embryo recovery in goats .this study sho...

The gradually varied surface was introduced and studied in digital and discrete spaces by Chen. The basic idea of introducing gradually varied surfaces is to employ a purely discrete interpolation algorithm to fit a discrete surface when the desired surface is not required to be “smooth.” In this paper, we generalize the concept of gradually varied surfaces. A digital surface is defined as a ma...

Philosophic concepts and pragmatic approaches toward improved understanding of the effect of drugs in the hepatocyte are reviewed. No set pattern of studies is advocated but rather observations are encouraged within the framework of studies that provide for varied exposure of the hepatocyte. Clinical usage should be imitated to provide earliest possible indications of toxicity in man. The need ...

In this chapter, we present an industrial case study for the creation and usage of architectural knowledge. To establish the context of our usage of architectural knowledge, we introduce business domain, service portfolio, and knowledge management approach of the company involved in the case in a first section. In this first section, we briefly review general architectural concepts such as view...

This paper presents the idea of Usage Oriented Requirements Engineering, an extension of Use Case Driven Analysis. The main objective is to achieve a requirements engineering process resulting in a model which captures both functional requirements and system usage aspects in a comprehensive manner. The paper presents the basic concepts and the process of Usage Oriented Requirements Engineering,...

variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...
