Heterotrophic plate count (HPC) constitutes a common indicator for monitoring of microbiological water quality in distribution systems (DS). This paper aims to identify factors explaining the spatiotemporal distribution of heterotrophic bacteria and model their occurrence in the distribution system. The case under study is the DS of Quebec City, Canada. The study is based on a robust database r...

The purpose of distributed generation systems (DGS) is to enhance the distribution system (DS) performance be better known with its benefits in power sector as installing (DG) units into DS can introduce economic, environmental and technical benefits. Those obtained if DG units' site size properly determined. aim this paper studying reviewing effect connecting on transmission efficiency, reacti...

Chondroitin sulfate (CS) and dermatan sulfate (DS) are expressed in significant amounts in the brain and play important roles in the development of the central nervous system in mammals. CS and DS structures are often found in a single CS/DS hybrid chain. The l-iduronic acid (IdoA)-containing domain, which defines a DS-type domain, appears key to the biological functions of the CS/DS hybrid cha...

We present a comprehensive theory of the Dyakonov-Shur (DS) plasma instability in current-biased graphene transistors. Using hydrodynamic approach, we derive equations describing DS two-dimensional electron fluid at arbitrary values drift velocity. These nonlinear together with Maxwell's are used for numerical analysis spatial and temporal evolution system after is triggered by random current f...

Voltage instability and power loss are significant problems in distribution Systems (DS). However, these usually mitigated by the optimal integration of distributed generation (DG) units DN. In this regard, location size DGs crucial. Otherwise, System performance will deteriorate. This study is conducted to place radial DS. Mayfly Algorithm (MA) used determine placement minimize loss, increase ...

Abstract In the distribution system, decentralized generation is incorporated to maximize system reliability and economic stability, avoid redundancy in system. The efficient implementation of distributed‐generations (DGs) a distribution‐system (DS) can be done by employing demand‐side management (DSM). this research proposal, location size selection DGs DS considering DSM accomplished using hy...

Direction selectivity (DS) is an important neuronal property in the visual system, but how DS is generated beyond the retina remains controversial. Here, we report a close correspondence between the preferred direction (PD) and the morphology of DS cells in the optic tectum. Ca(2+) imaging in cells expressing the genetically encoded Ca(2+) indicator GCaMP3 and multiphoton-targeted patch-clamp r...

The proteoglycan decorin and its associated glycosaminoglycan (GAG), dermatan sulfate (DS), regulate collagen fibril formation, control fibril diameter, and have been suggested to contribute to the mechanical stability and material properties of connective tissues. The spatial distribution and orientation of DS within the tissue are relevant to these mechanical roles, but measurements of length...

We have recently reported reduced telomere length in T lymphocytes of individuals with Down syndrome (DS) and dementia due to Alzheimer's disease (AD). We have now replicated and extended that study by finding that people with DS and mild cognitive impairment (MCI-DS) also have shorter telomeres than people with DS without MCI-DS. Additional new findings demonstrated that light intensity measur...
