Abstract The early 1970s brought fundamental transitions in international scientific collaboration that significantly affected the relations global patterns are still relevant today. This article uses a multi-perspective approach to argue underlying condition for globalization of science diplomacy was increasing participation recently independent countries technoscientific affairs, examining cr...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
This paper explores whether Ethiopia's rapid economic growth is transformative enough for the country to eventually catch up with high-income countries. It does so by exploring change and continuity of four elements social capability from 1950 2020: structural transformation, inclusion state's autonomy accountability. finds that modestly strengthened until mid-1970s, then weakened early 2000s, ...
Introduction: Reverse osmosis (RO) is best known for its use in desalination (removing the salt from seawater to get fresh water), but since the early 1970s it has also been used to purify fresh water for medical, industrial, and domestic applications. The aim of this research was the performance study of reverse osmosis plants for water desalination in Bandar-Lengeh, Iran. Materials and Meth...
BACKGROUND The proportion of low birthweight babies (LBW: 1500-2499 g) in Japan decreased steadily from 1950 to the 1970s. However, since then it has started to increase consistently, the reason for which has not been discussed in detail. METHODS Trends of birthweight and the two known factors for low birthweight (maternal smoking, and pre-pregnancy weight) were analysed with vital statistics...
Since its origins in the 1970s and eighties, Social Structure of Accumulation (SSA) research has moved away from its early emphasis on organization-level dynamics of profit-making, reinvestment, and labor process (within their broader institutional setting). Recent authors have begun to explore ways of renewing this emphasis. This paper proposes using the theory of “organizational capabilities”...
Since the publication of the first paper on "cytochrome P450" in 1962, the biochemical research on this novel hemoprotein expanded rapidly in the 1960s and the 1970s as its principal roles in various important metabolic processes including steroid hormone biosynthesis in the steroidogenic organs and drug metabolism in the liver were elucidated. Establishment of the purification procedures of mi...
Natural rate misperceptions generated the potential of significant upward inflationary pressure in the late 1960s and 1970s. With the activist stabilization policy in place during this period, these misperceptions led to a series of persistent policy errors that inadvertently destabilized the economy and inflation expectations. We develop a model that highlights the interaction of these policy ...
