Domestic Wastewater Treatment

A Multi-stage Reversing flow Bioreactor (MRB) was developed by the Public Works Research Institute in 1986. It utilizes the symbiotic interaction between anaerobic bacteria (sulfate reducing bacteria) and microaerobic bacteria (Beggiatoa=filamentous sulfur oxidizing bacteria) for self-granulated pellet formation. A MRB Pilot plant for domestic wastewater treatment (design capacity was 225 m3/day) was constructed in 1988. After several modifications of the initial design, stable pellet formation and high performance were achieved. This paper describes the results of the pilot plant operation.

Maximum Measurement Error

High performance and complex system-on-chip (SoC) design require a throughput and stable timing monitor to reduce the impacts of uncertain timing and implement the dynamic voltage and frequency scaling (DVFS) scheme for overall power reduction. This paper presents a multi-stage timing monitor, combining three timing-monitoring stages to achieve a high timing-monitoring resolution and a wide timing-monitoring range simultaneously. Additionally, because the proposed timing monitor has high immunity to the process–voltage–temperature (PVT) variation, it provides a more stable time-monitoring results. The time-monitoring resolution and range of the proposed timing monitor are 47 ps and 2.2 µs, respectively, and the maximum measurement error is 0.06%. Therefore, the proposed multi-stage timing monitor provides not only the timing information of the specified signals to maintain the functionality and performance of the SoC, but also makes the operation of the DVFS scheme more efficient and accurate in SoC design.

The Impact

In this work, aramid fibers were used to develop new, high-performance fabrics for high-temperature protective clothing. The research was based on the impact of the weave structure on fabric resistance to radiant heat. The goals of the research were primarily related to the development of new fabric structures created by the weave structure, which gives better protection of the body against high temperatures in relation to the standard weave structures that are used today. According to the results obtained it can be concluded that the fabric weave significantly affects the fabric structure, which consequently determines the effectiveness of protection against high temperatures. The justification for the use of multi-weft and strucks weave structure, which provides greater thermal protection and satisfactory breathability than commonly used weave structures, was ascertained.

Background: The phenomenon of almost loss of consciousness (A-LOC) is although known to the aviation fraternity since the 1980s, it is not well researched. Very few studies have attempted to elaborate the characteristics of A-LOC. The present study is a retrospective analysis which has endeavored to address the lacunae in literature. Materials and Methods: A retrospective analysis of the G training data in high-performance human centrifuge for a time span of 4 years (2009–2013) was carried out. Results: A total of 71 A-LOC incidents were reported and were analyzed for better understanding of A-LOC. On the basis of findings such as nystagmus, maintenance of postural tone, convulsions, amnesia, and dreams during A-LOC, neurophysiology of A-LOC has been hypothesized. Conclusion: The presence of nystagmus and maintenance of body posture suggest intact vestibulo-ocular reflex and sensory-motor tract, respectively. Non-recollection of dreams, amnesia suggests breach in memory and/ or information processing for higher functions. The mechanism of A-LOC in toto can be explained by regional differences in blood flow and vulnerability of cerebral centers to ischemic hypoxia. Convulsions in A-LOC could be attributed to hyperexcitability of nerve fibers due to hypoxia.
