This ethnographic vignette, part of a special section on flash ethnography, describes the responses bystanders and security state to an explosion at gas station in Fallujah, Iraq, during author's fieldwork 2021–2022.

The purpose of this paper is to contribute to the challenge of transferring know-how, theories and methods from design research to the design processes in information science and technologies. More specifically, we shall consider a domain, namely data-science, that is becoming rapidly a globally invested research and development axis with strong imperatives for innovation given the data deluge ...

The spread of online reviews, ratings and opinions and its growing influence on people’s behavior and decisions boosted the interest to extract meaningful information from this data deluge. Hence, crowdsourced ratings of products and services gained a critical role in business, governments, and others. We propose a new reputation-based ranking system utilizing multipartite rating subnetworks, t...

hroughout history, astronomers have been accustomed to data falling from the sky. But our relatively newfound ability to store the sky's data in " clouds " offers us fascinating new ways to access, distribute, use, and analyze data, both in research and in education. Here we consider three interrelated questions: (1) What trends have we seen, and will soon see, in the growth of image and data c...

The hydroelastic interaction between an underwater explosion and an elastic plate is investigated num- erically through a domain-decomposition strategy. The three-dimensional features of the problem require a large computational effort, which is reduced through a weak coupling between a one-dimensional radial blast solver, which resolves the blast evolution far from the boundaries, and a three-...

Cosmological GRBs are discussed with an emphasis on their plausible connection with black holes. GRBs can be triggered by collapse of stellar-mass objects that leads to formation of a black hole and a transient debris disk with a huge accretion rate. The disk is believed to produce a relativistic jet (“fireball”) that expands and emits to infinity the observed burst of gamma-rays. This accretio...

Whether or not a chemical reaction in a fluid leads to an explosion is shown to depend on four timescales: that for the chemical reaction to heat up the fluid containing the reactants and products, for heat conduction out of the reactor, for natural convection in the fluid, and finally for chemical reaction. This approach is developed for an irreversible, n-th order chemical reaction, A → B occ...

This overview ties together the various articles by relating them to the current debate on whether, and how, the Medicare program can add outpatient drugs as a covered benefit. The unifying theme for most of the articles is that they outline possible ways of administering a drug benefit and discuss policy issues that will arise, based on Health Care Financing Administration (HCFA) experiences o...

INTRODUCTION In parallel with technological improvements, humankind encounter with equipments/devices transforming chemical energy to electrical energy. Especially automobile batteries, watch and mobile phone batteries are the most encountered ones. In the literature, there are mainly facial burn cases due to mobile phone battery explosion. On the other hand very few examples of serious lower l...
