Cities, Disaster Risk and Adaptation

Worldwide, disasters and climate change pose a serious risk to sustainable urban development, resulting in escalating human and economic costs. Consequently, city authorities and other urban actors face the challenge of integrating risk reduction and adaptation strategies into their work, although related knowledge and expertise are still scarce. Cities, Disaster Risk and Adaptation explores ways

OMAC: An Opportunistic Medium Access Control Protocol for IEEE 802.11 Wireless Networks

The ambitious goal of the upcoming IEEE 802.11ax (HEW) standard for wireless LANs (WLANs) to enhance throughput by four times (and beyond), compared with IEEE 802.11ac, demands a radical improvement of present medium access control (MAC) functionality. To this end, a promising paradigm would be a graceful migration towards new MAC protocols which incorporate higher certainty in their decisions. Ho

A polymer based electrode array for recordings in the cerebellum

A polymer foil based array with 9 gold electrodes for chronic electrophysiological recordings in the CNS has been developed. A polymer, SU-8, is pattered using photolithography techniques used every day in micro fabrication. This is beneficial if the electrode would be manufactured on a large scale basis. The technique makes it easy to adapt the array to best fit the structure of interest at the t

The Use of OECD Commentaries as Interpretative Aids : The Static/Ambulatory-Approaches Debate Considered from the Perspective of International Law

Since many years, international tax law experts debate the relevance of changes to OECD Commentaries for the purpose of the interpretation of previously concluded tax treaties. Although, generally, most experts seem averse to the idea of an ambulatory approach to the usage of OECD Commentaries, they are reluctant to exclude this idea altogether. Such a position raises an important issue of justifi

Ormen och byggmästaren - hebraismer och gnosis hos Carl William Hansen

The article examines how the Danish esoteric and heterodox Freemason Carl William Hansen (also known as Ben Kadosh) used and reinterpreted themes and motifs from the Old Testament and various Gnostic writings when constructing his unusual and aberrant philosophical system in his pamphlet "The Dawn of a New Morning: The Return of World Architect".

The evolution of photosynthesis and its environmental impact

Photosynthesis in plants is a very complicated process, utilizing two photosystems in series to carry out the very energy-demanding process of oxidizing water to molecular oxygen and reducing carbon dioxide to organic compounds. The first photosynthetic organisms, living more than 3.4, perhaps even 3.8 Ga, i.e. American billion (109) years ago, carried out a simpler process, without oxygen product

Saudi Arabia

Comparable country profile that describes the evolution and practice of corporate Sustainability and Responsibility (CSR) in Saudi Arabia.

Conservation of mutual and directed information

Two conservation laws for mutual information in terms of directed informations between two synchronized sequences of random variables are derived, the first for the case of no conditioning and the second for the case of causal conditioning on a third synchronized sequence. As a byproduct of the derivation of the first conservation law, the directed information specifying the feedback flowing from

What is Wrong with Extinction? - The Answer from Anthropocentric Instrumentalism

The book contains the first part of an investigation aimed at finding out why it is morally wrong (at least prima facie) to cause species to go extinct. That it is morally wrong seems to be a very basic and widely held intuition. It seems reasonable that a moral theory worth taking seriously ought to be able to account for that intuition. The most common attempt to answer our question is to refer

Changes in the quantities of violaxanthin de-epoxidase, xanthophylls and ascorbate in spinach upon shift from low to high light

Zeaxanthin, a carotenoid in the xanthophyll cycle, has been suggested to play a role in the protection against photodestruction. We have studied the importance of the parameters involved in zeaxanthin formation by comparing spinach plants grown in low light (100 to 250 mol m-2 s-1) to plants transferred to high light (950 mol m-2 s-1). Different parameters were followed for a total of 11 days. Our
