Abstract The volume of water losses depends largely on the approach to active leakage control networks. Losses comprise physical (leakages transmission and/or distribution networks, at utility’s storage tanks, and service connections), commercial (unauthorised consumption metering inaccuracies data handling errors) unbilled authorised (unbilled metered unmetered consumption). Reduction real may...

selfish director, however, might restrict himself to poaching the best staff members from the university without giving anything back. Writing for the daily paper Frankfurter Allgemeine Zeitung (FAZ), the nine university professors, led by biochemist Günter Blobel from Rockefeller University, have outlined what they call the “unsolved MaxPlanck problem” of German research, namely the artificial...

there are human and animal health concerns related to drainage systems because nutrients, especially nitrogen and phosphorus, can contaminate water supplies. a field study was conducted on consolidated paddy fields of sari agricultural sciences and natural resources university, northern iran (36.3°n, 53.04°e), to determine the effect of subsurface drain depth and spacing on nitrogen (n) and pho...

TCP is a popular transport protocol used in present-day internet. When packet losses occur, TCP assumes that the packet losses are due to congestion, and responds by reducing its congestion window. When a TCP connection traverses a wireless link, a significant fraction of packet losses may occur due to transmission errors. TCP responds to such losses also by reducing congestion window. This res...
