Post-Detonation Afterburning of High Explosives

High performance of an explosive compound with respect to afterburning requires sufficient combustible properties of the explosive, and a careful determination of the most appropriate charge positioning to achieve the desired afterburning effect. Understanding the physical processes of post-detonation afterburning and how these are affected by the surroundings, e.g. the Height of Burst (HoB), faciHigh performance of an explosive compound with respect to afterburning requires sufficient combustible properties of the explosive, and a careful determination of the most appropriate charge positioning to achieve the desired afterburning effect.

From a state of shock to agency in liminality, Syrians and their children on the move

Less than 10% of the estimated total of 11 million Syrians who fled their homes, have actually reached Europe; around 4.8 million Syrian refugees live in neighbouring countries and over 6.6 million are internally displaced people (IDP) within Syria (Migration Policy Centre, 2016). In 2014, the author travelled back to northern Syria, where she conducted anthropological fieldwork in the past betwee

Revising GDP estimates in sub-Saharan Africa : lessons from Ghana

The upward revision of GDP in Ghana, announced in November 2010, attracted considerable attention in the media, in the development community, and from development scholars. This paper clarifies what caused this upward revision and discusses how the revision was handled. Many other countries have outdated base years and do not utilize data sources fully. They can learn from the Ghanaian experience

Genetic variation in the ADIPOQ gene, adiponectin concentrations and risk of colorectal cancer : a Mendelian Randomization analysis using data from three large cohort studies

Higher levels of circulating adiponectin have been related to lower risk of colorectal cancer in several prospective cohort studies, but it remains unclear whether this association may be causal. We aimed to improve causal inference in a Mendelian Randomization meta-analysis using nested case–control studies of the European Prospective Investigation into Cancer and Nutrition (EPIC, 623 cases, 623

Users and Producers of African Income : Measuring African Progress

This article traces how African incomes have been measured through history, and shows that there has been a conflict of aims between producers and users of national income estimates. Politicians and international organizations seek income measures that reflect current political and economic priorities and achievements. Thus the importance given to markets, the state, and peasants in the estimates

Sensitization and cross-reactivity patterns of contact allergy to diisocyanates and corresponding amines : Investigation of diphenylmethane-4,4'-diisocyanate, diphenylmethane-4,4'-diamine, dicyclohexylmethane-4,4'-diisocyanate, and dicylohexylmethane-4,4'-diamine

Background: Isocyanates are used in polyurethane production. Dermal exposure to isocyanates can induce contact allergy. The most common isocyanate is diphenylmethane diisocyanate used for industrial purposes. The isomer diphenylmethane-4,4'-diisocyanate (4,4'-MDI) is used in patch testing. Diphenylmethane-4,4'-diamine (4,4'-MDA) is its corresponding amine. Concurrent reactions to 4,4'-MDI and 4,4'

Patients’ Satisfaction with Lower-limb Prosthetic and Orthotic Devices and Service delivery in Sierra Leone and Malawi

BACKGROUND People with disabilities have the right to personal mobility and available and affordable assistive technology, according to the Convention of Rights of Persons with Disabilities. Few studies have investigated overall satisfaction with prostheses fabricated using low-cost technology. Evidence-based recommendations for prosthetic and orthotic services in low-income countries are needed i

Measurement of the W boson polarisation in tt¯ events from pp collisions at √s = 8 TeV in the lepton + jets channel with ATLAS

This paper presents a measurement of the polarisation of W bosons from tt¯ decays, reconstructed in events with one high-pT lepton and at least four jets. Data from pp collisions at the LHC were collected at s = 8 TeV and correspond to an integrated luminosity of 20.2 fb- 1. The angle θ∗ between the b-quark from the top quark decay and a direct W boson decay product in the W boson rest frame is se
