Organic pollution of rivers by wastewater discharge from human activities negatively impacts people and ecosystems. Without treatment, pollution control relies on a combination of natural degradation and dilution by natural runoff to reduce downstream effects. We quantify here for the first time the global sanitation crisis through its impact on organic river pollution from the threats of (1) i...

Since the demand for more bandwidth, agile infrastructures and services grows, it becomes challenging for Service Providers like GÉANT to manage the proprietary underlay, while keeping costs low. In such a scenario, Software Defined Networking (SDN), open hardware and open source software prove to be key components to address those challenges. After one year of development, SDX-L2 and BoD, the ...

The demand for efficient, scalable and cost effective mobile information access systems is rapidly growing. Radio frequency broadcast plays a major role in mobile computing, and there is a need to provide service models for broadcasting information according to mobile users’ needs. In this paper we present a model called Broadcast on Demand (BoD), which provides timely broadcasts according to r...

In this paper, we consider the mathematical formulation and analysis of an optimal control problem for a nonlinear Dissolve Oxygen(DO)/ Biological Oxygen Demand(BOD) system with logistic growth term. In the BOD/DO system studied by Bermúdez [2] this logistic growth term is not included. We study the existence and uniqueness of solution for the nonlinear system as well as the existence and uniqu...

We investigated physical, chemical, and biological variables contributing to biochemical oxygen demand (BOD) in 17 North Carolina lotic and lentic water bodies affected by mild to severe hypoxia. Phytoplankton production created the dominant reservoir of labile carbon driving BOD, and subsequent hypoxia, in a Piedmont river subject to algal blooms, three urban streams, a set of anthropogenicall...

The Bod Pod has been found to be reliable/valid against several criterion methods, including hydrostatic weighing and dual-energy x-ray absorptiometry, and under different conditions, such as clothing, dehydrated states, and body temperature changes. However, questions remain regarding the effects of an acute bout of exercise. Therefore, the purpose was to determine the effects of an acute bout...

A physicochemical study for the treatment of pharmaceutical wastewater was performed. Objective of the laboratory investigation was to study the removal of color, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), turbidity and phenol and bring them up to the allowable limits for reuse purposes. Efficiency of coagulation, flocculation, sedimentation, sa...

Hawaii is the only state in the USA that grows, processes, and roasts coffee. Coffee processing, however, poses some challenges. One is the processing water, which must be treated, and should be re-used. We surveyed and collected several coffee processing water samples, both influent and effluent, from four small-scale (2-5 ha) coffee farms in Kona on Hawaii (Big Island), and from a large (1200...

There are many system proposals for satellitebased broadband communications that promise high capacity and ease of access. Many of these proposals require advanced switching technology and signal processing on-board the satellite(s). One solution is based on a geo-synchronous (GEO) satellite system equipped with on-board processing and on-board switching. An important feature of this system is ...

Body dysmorphic disorder an obsessive-compulsive and related disorder that is common and usually causes substantial distress and impairment in psychosocial functioning. is associated with markedly poor quality of and rates of suicidal ideation and behavior. The pharmacologic approach is a serotonin reuptake inhibitor, often at relatively high doses; serotonin reuptake inhibitors are also recomm...
