INTRODUCTION 4 This subject, Urban Wet-Weather Flows, was comprised of three basic subareas – combined-sewer 5 overflows (CSOs), sanitary-sewer overflows (SSOs), and stormwater discharges. Major proceedings 6 related to wet-weather flow (WWF) published during 2000 were the following: (1) ASCE EWRI 7 Conference – Bridging the Gap: Meeting the World’s Water and Environmental Resources Challenges ...

Two new antibiotics, A-218 and K-41, were isolated from strains identified as Streptomyces hygroscopicus. The antibiotics are characterized as polycyclic polyether compounds and are active against gram-positive bacteria.

This paper describes a method to duplicate the structural performance of a graphite-reinforced cementitious composite as the mix proportions and constituents of its cementitious matrix are varied. This is accomplished by placing a test specimen constructed using a modified mixture over a reinforcing scheme identical to that of a control standard and then matching the end deflection of these sam...

To estimate multiple-input multiple-output (MIMO) channels, invariable step-size normalized least mean square (ISSNLMS) algorithm was applied to adaptive channel estimation (ACE). Since the MIMO channel is often described by sparse channel model due to broadband signal transmission, such sparsity can be exploited by adaptive sparse channel estimation (ASCE) methods using sparse ISS-NLMS algorit...

A comparative study is presented of the estimated wind load capacities of low-rise steel building frames based on loading patterns ~magnitude and distribution! established from aerodynamic databases on the one hand, and on patterns specified in the ASCE 7 Standard on the other. The estimated capacities are based on the assumption, verified by numerous sets of calculations, and also used in the ...

The title compound, C(51)H(78)N(4)O(12), is a derivative of rapamycin, a triene macrolide anti-biotic mol-ecule isolated from Streptomyces hygroscopicus. The macrocyclic ring structure has 15 chiral centres, with one of the substituent hy-droxy groups giving an intra-molecular hydrogen bond to a ketone O-atom acceptor. The mol-ecules also form inter-molecular hy-droxy-ketone O-H⋯O hydrogen-bond...

Several concrete structures in tectonically active regions of the world are exposed to chloride ingress from seawater, saltwater, and other sources, making them vulnerable corrosion-induced deterioration. Although it is well-known that deterioration influences force-displacement behaviour corroded components under cyclic loading, no adequate provisions have been incorporated into state-of-pract...

We describe synaptic connections through which information essential for encoding efference copies reaches two coordinating neurons in each of the microcircuits that controls limbs on abdominal segments of the crayfish, Pacifastacus leniusculus. In each microcircuit, these coordinating neurons fire bursts of spikes simultaneously with motor neurons. These bursts encode timing, duration, and str...
