Smouldering fires in wood pellet silos are not uncommon. The fires are often difficult to deal with and extinguishment is a lengthy process. Injection of inert gasses to prevent oxygen from reaching the smouldering fire zone and suppress combustion is a new firefighting strategy. This article argues that injection of inert carbon dioxide into the silo headspace is unsafe. Carbon dioxide is gene...

To achieve sensitivity, comfort, and durability in vital sign monitoring, this study explores the use of radar technologies in wearable devices. The study first detected the respiratory rates and heart rates of a subject at a one-meter distance using a self-injection-locked (SIL) radar and a conventional continuous-wave (CW) radar to compare the sensitivity versus power consumption between the ...

Spoken user interfaces are conventionally either dialogue based or menu-based. In this paper we propose a third approach, in which the task of invoking responses from the system is treated as one of retrieval from the set of all possible responses. Unlike conventional spoken user interfaces that return a unique response to the user, the proposed interface returns a shortlist of possible respons...

Venting devices are commonly used to try to reduce the damage caused by any dust explosion that may occur in silo systems. In North America and Europe the sizing of these vent areas is governed by standards NFPA 68 and EN 14491 respectively, both of which have recently come into force. The aim of the present work was to compare these standards in terms of the cost of protecting against dust exp...

For many years, the health care community has used a silo approach to oral health, with little exception, treating the oral cavity as the sole province of the dentist, with no interaction with the medical profession. However, as research shows links between periodontal disease and diabetes, stroke, heart disease, and peripheral arterial disease, it seems clear that the silo approach to oral hea...

The aim of this study was isolation and identification fungi producing aflatoxin B1 from wheat which stored for four months in some silos Baghdad , including Al Taji Silo, Khan Bani Saad Silo Dhari Silo. Those Silos were included the agricultural plan marketing season 2020. Different types obtained. They initially identified according to cultural morphological characteristics as Alternaria spp,...

I. Introduction Banking-style institutions have existed for over two thousand years and are even documented in the earliest civilizations. For example, in ancient Egypt and Mesopotamia, barley and grain were forms of currency and the grain silos and state warehouses acted as banks. 1 An ancient Babylonian clay tablet explains that city workers received wages denominated in liters of barley that...

Objective. To describe a profoundly immunocompromised (panleukopenia) child with septic shock who developed abdominal compartment syndrome (ACS) and was successfully treated with surgical decompression. Design. Individual case report. Setting. Pediatric intensive care unit of a tertiary children's hospital. Patient. A 32-month-old male with Fanconi anemia who underwent bone marrow transplantati...
