Background: Miniature neutron sources with high neutron flux have abundant applications in medicine, industry and researches. The most important general characteristic of miniature neutron sources is their diameter which is 3mm in average. In this research, we have surveyed and designed an Am-Be miniature neutron source fabrication. Materials and Methods: This investigation resulted in creation...

This paper fortifies and defends the so called Sufficiency Argument (SA) against Classical Invariantism. In Sect. 2, I explain the version of the SA formulated but then rejected by Brown (2008a). In Sect. 3, I show how cases described by Hawthorne (2004), Brown (2008b), and Lackey (forthcoming) threaten to undermine one or the other of the SA’s least secure premises. In Sect. 4, I buttress one ...

The study population is a group of key Iranian informants, faculty members, and doctoral graduates with scientific expertise and work experience in the field of entrepreneurship, especially academic entrepreneurship and international entrepreneurship, and managers of knowledge-based academic...

In network organisations and electronic commerce control mechanisms to guarantee inter-organisational contract compliance are important tools to enhance trust in a fair business transaction. We propose the e-value/control design methodology for designing controls for network organisations. The e-value/control design methodology is an extension of the e-value design methodology for business mode...

Background: Population ageing and improvements in healthcare mean the number of people living with two or more chronic conditions, ‘multimorbidity’, is rapidly increasing. This presents a challenge to current disease-specific care delivery models. Adherence prescribed medications appears particularly challenging for individuals multimorbidity, given often-complex dru...

We design an interactive stack in the setting of stream processing functions. The design passes through a series of abstraction levels relating different views of the stack component. The external view describes the component’s input/output behaviour, the transition view captures the stepwise transitions, and the state-based view discloses the internal structure. The different descriptions can ...
