Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word technology can also mean the products resulting from such efforts, including both tangible products such as tools or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life. Technological advancements have led to significant changes in society. The earliest known technology is the stone tool, used during prehistory, followed by the control of fire—which in turn contributed to the growth of the human brain and the development of language during the Ice Age, according to the cooking hypothesis. The inve…

Human Capital, Tangible Wealth, and the Intangible Capital Residual. Since income is the return on wealth, the total wealth of a country should be around twenty times its GDP. Instead, the average observed ratio from the System of National Accounts (SNA) is a factor of 2.6–6.6. Clearly, wealth accounts are incomplete. Estimating the value of the most obvious omission, human capital, using the lifetime income approach for a sample of thirteen (mostly high-income) countries yields a mean share of human capital in total wealth of 63 per cent—four times the value of produced and fourteen times that of natural capital. But for selected high-income countries an average of 25 per cent of total wea…

Introduction. The introduction to the book frames its study of the architectural and urban spaces that shape cities’ tangible heritage, considering the urban networks, residential spaces and materials and methods of construction. The book also examines the parameters governing societies’ intangible heritage by defining: (i) individuals according to local identities, cultures and religions, (ii) behaviours rooted in local ways of life and social values, and (iii) practices including local customs, feasts and festivals. It outlines the relevance of globalisation to the preservation of tangible and intangible heritage and introduces the different chapters and what they will contribute to the b…

Nutritional adequacy and novel food products.. Adequate nutrition is an essential requirement for health, growth, prevention of nutritional diseases and normal physiological functions throughout life. Although there has been significant progress in agriculture, food systems, nutrition science, food insecurity and dietary insufficiency continue to be a significant public health challenge globally. This might be due to factors including limited dietary diversity, socioeconomic inequalities, infectious diseases, climate change and poor governance. This chapter thoroughly explains the concept of nutritional adequacy, its definition, evolution over time and the components of an adequate diet. It…

Shannon Capacity and Related Graph Invariants for Lexicographic Products.. This paper studies the Shannon capacity of lexicographic products of finite simple graphs, together with the Lovász theta function and the fractional Haemers number. The Shannon capacity is proved to be supermultiplicative under lexicographic products in either order, and these products are compared with the strong product. We explicitly construct three countably infinite families of lexicographic powers based on the Schläfli graph, the McLaughlin graph, and its second subconstituent; in each family, pairing each member with its complement yields strict supermultiplicativity and arbitrarily large multiplicative gaps.…

Design technology, or D.T., (also Digital Delivery (DD)) is the study, design, development, application, implementation, support and management of computer and non-computer based technologies for the express purpose of communicating product design intent and constructability. Design technology can be applied to the problems encountered in construction, operation and maintenance of a product. At times there is cross-over between D.T. and Information Technology, whereas I.T. is primarily focused on overall network infrastructure, hardware and software requirements, and implementation, D.T. is specifically focused on supporting, maintaining and training design and engineering applications and…
