OBJECTIVE The electrocardiogram (ECG) is an important, available, and inexpensive diagnostic tool to assess cardiac symptoms. Few studies address the prevalence of ECG abnormalities or changes of a normal tracing in ECG in outpatients. Our objective was to evaluate ECGs of adult outpatients to determine whether changes from a normal tracing could disclose the patients' cardiovascular health sta...

Municipal wireless network is a recently established infrastructure of city-based wireless network, which provides mainly outdoor broadband wireless access to Internet for public usages. The municipal network is usually regarded as a public-utility service, which not only delivers well connected broadband services in the city at an affordable price but also promotes society interaction and brin...

Tkc process air emissions from municipal wastewater treatmentplants primarily consist of hydrogen sulj?degas, along with other oigano-sulfilr compounds, and some trace quantities of volatile oiganic compounds (VOC). Various Federal and/or State Uegulativtzs require monitoring, and control of these em&sions dooutn to some specijied levels. At the Deer Island Wastewater Treatment Plant of the Mas...

This article answers three questions of J. Almeida. Using combinatorial, algebraic and topological methods, we compute joins involving the pseudovariety of finite groups, the pseudovariety of semigroups in which each idempotent is a right zero and the pseudovariety generated by monoids M such that each idempotent of M\{1} is a left zero.

This paper presents the results of an evaluation of Field Capacity of municipal solid waste at the University of Maiduguri dumpsite. The work describes the methodology and the devices designed for the determination of field capacity of municipal solid waste, in which a lysimeter was constructed to simulate the activities within the refuse dumpsite. The method consisted of applying dynamic compa...

In this paper, we consider network transmissions over a single or multiple parallel two-hop lossy paths. These scenarios occur in applications such as sensor networks or WiFi offloading. Random linear network coding (RLNC), where previously received packets are re-encoded at intermediate nodes and forwarded, is known to be a capacity-achieving approach for these networks. However, a major drawb...

Organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. Composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. An integrated approach of composting methodology was tested for municipal solid waste management. Solid waste first was composted and after 22 days, was...

This paper presents the Clarified system for passive network analysis. It is based on capturing complete packet history and abstracting it in form of different interactive high-level visual presentations. They allow for drilling from the high-level abstractions all the way down to individual packets and vice versa. The applicability of the system is demonstrated with the daily management of a l...

Traditional leaders have a formal role in South Africa’s post-apartheid local government, and in some cities in the country, notably in KwaZulu-Natal, their presence has presented some important political challenges. This paper explores the relationship between longstanding institutional arrangements which support chiefdoms and traditional authority control over land and development, and the em...
