Blockchain is widely considered a new key technology. The Foundation for Technology Assessment (TA-SWISS) has proposed a comprehensive assessment of blockchain technologies. With this publication, TA-SWISS provides the much-needed social contextualisation of blockchain. The first, more technical part of the study takes an in-depth look at how blockchain functions and examines the economic potential of this technology. By analysing multiple real-world applications, the study sheds light on where the blockchain has advantages over traditional applications and where existing technologies continue to be the better solution. The second part of the study examines how blockchain became mainstream. It explores the origins of blockchain in the early history of information technology and computer networks. The study also reveals the impact blockchain has on industrial and public spaces. Finally, it discusses the social implications and challenges of blockchain against the background of a new socio-technical environment.

Abstract: The present study evaluates the economic viability of four different models of beef cattle production in the rio Vermelho hydrographic basin. The study focuses on the traditional extensive ranching system, which was compared to three intensive systems, one based on low levels of concentrated supplementation, a second with low levels of concentrated supplementation and confinement for fattening and an intensive grazing system, with supplementation during the dry and rainy seasons. The investments were estimated for the different levels of technical specifications of each system. The net present values and internal return rate were used for the assessment of the economic viability of the project, considering the minimum rate of attractiveness, equivalent to the inflation-adjusted savings interest rate (6.17%). The continuity of the sector was evaluated based on the gross and net margins, and profitability rates, where the system is already installed. All four systems had gross and net margins and profitability consistent with their economic sustainability over both the short and long terms. However, only two systems (reduced consumption of concentrated supplements and the intensive grazing system) were economically viable as start-ups.

Background: Wasting cases for children under five are currently increasing, the high risk of malnutrition continues to increase so that it has an effect on increasing the prevalence of nutritional problems which results in decreased productivity.Objectives: To estimate the economic potential lost due to wasting in children under five.Methods: Descriptive research, by processing data from various related agencies which are all in the form of secondary data. Calculate using the Konig (1995) formula and a correction factor from Horton's (1999) study. The research activities are carried out starting July 2018 until September 2018.Results: Nationally based on the prevalence of wasting in children under five in 2013 amounting to IDR 1.042 billion - IDR 4.687 billion or 0.01% - 0.06% of the total GDP of Indonesia.Conclusion: The prevalence of high wasting problems can increase the potential for economic losses and affect the economy of a country especially in developing countries and one of them is Indonesia.

Epilachna vigintioctopunctata is an important pest that causes considerable economic losses to many crops including egg-plants. The crude aqueous extracts of leaves from three indigenous plants namely Ricinus communis, Calotropis procera and Datura metel were used against this beetle aiming at its control under laboratory conditions. Larvicidal bioassays of the extracts showed the following order of toxicity: R. communis (LC50=18.40%) > C. procera (LC50=23.70%) > D. metel (LC50=29.61%). Subsequent data on some vital life-history traits were promising because the extracts significantly reduced both oviposition and egg-hatch, prolonged larval duration (P<0.001), and inhibited pupae formation and adult emergence (P<0.05). However, female ratio was not significantly affected by the treatments. Relevance of these findings on the control of this phytophagous species has been discussed.

Biopiracy as “a silent disease” is hardly detectable because it does not leave traces frequently. The corporate hijacking of food is the most important health hazard in this era; giant commercial enterprises are using intellectual property rights to patent indigenous medicinal plants, seeds, genetic resources, and traditional medicines. The new era of biotechnology relies on the genes of living organisms as raw materials. The “Gene Rush” has thus become similar to that of the old “Gold Rush.” Sri Lanka has been spotted in the top 34 biodiversity hotspots globally. Moreover, localized in the tropics, human generations in Sri Lanka have utilized the array of plant species for herbal treatments and treatment of diseases. Sri Lanka after its 30-year civil war is moving towards a solid growth and conservation of the environment which is a major component in a sustainable development where the conservation of biodiversity plays a significant role. In this paper, we present an overview of typical cases of global biopiracy, bioprospecting via introduction of cost-effective deoxyribonucleic acid (DNA) fingerprinting and international protocol with Private-Public-People Partnership concept as excellent forms of utilization of natural resources. We propose certain perspectives as scientists towards abolishing biopiracy and also to foster the fair utilization of natural resources; since the economy of most developing countries is agriculture based, the gross domestic product of the developing countries could be increased by enhanced bioprospecting via introduction of cost-effective DNA fingerprinting technologies and thus not being a pray of corporate hijacking.“Biopiracy is biological theft; illegal collection of indigenous plants by corporations who patent them for their own use” (Vandana Shiva).

An Experiment was conducted in the laboratory of the Division of Entomology, Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh to evaluate the efficacy of four indigenous plants parts such as leaves of raintree (Albizia saman), riot lata (Mikania micrantha), pithraj (Aphanamixis polystachya) and seeds of mahogani (Swietenia macrophylla) with methanol extracts at the rates of 10.0, 7.5, 5.0 and 2.5% for their direct toxicity against the pulse beetle, Callosobruchus chinensis (L.). Among the four plants extracts tested, pithraj leaf showed the highest (52.28%) mean repellency effect followed by riot lata (Mikania) leaf extract (46.07%), mahogani seed extract (38.79%) and raintree leaf extract (25.13%). On the basis of mean repellency rate, it was found that mahogany seed, pithraj leaf and riot lata (Mikania) leaf extracts were in the same repellency class i.e. Class Ill and except raintree leaf (Class II).DOI: http://dx.doi.org/10.3329/jesnr.v7i2.22224 J.

In many scholarly disciplines, books – not articles – are the norm. As print runs become smaller, the question arises whether publishing monographs in open access helps to make their contents globally accessible. To answer this question, the results of multiple studies on the usage of open access books are presented.The research focuses on three areas: economic viability; optimization of open access monographs infrastructure and measuring the effects of open access in terms of scholarly impact and societal influence. Each chapter reviews a di?ferent aspect: book sales, digital dissemination, open licenses, user communities, measuring usage, developing countries and the effects on citations and social media.
