The title compound α-ammonium iron(III) bis-[hydro-gen arsenate(V)], α-NH4Fe(HAsO4)2 (or poly[ammonium bis-(μ-hydro-gen arsenato)ferrate(III)], {NH4[Fe(HAsO4)2]} n ), syn-the-sized hydro-thermally, is isostructural with NH4Fe(HPO4)2. Condensation of the hydro-gen arsenate groups with FeO6 coordination octa-hedra via common corners results in an overall three-dimensional framework containing int...

This paper describes a software tool called Hydro Planner, being developed as part of CSIRO’s Water for a Healthy Country National Research Flagship Program. The main purpose of Hydro Planner is to enable urban water planners and managers to adopt a systems approach to obtain an improved understanding of how water, wastewater and stormwater systems interact with each other and with natural wate...

The attenuation of engine vibration transmitted to a chassis has been a major focus in the automotive community for the increase of comfort for the driver and passengers. A hydro-mount system is designed to reduce the transmission of engine vibration to the chassis. It is also used for supporting the static load by an engine weight. In this paper, we present a modeling and parameter estimation ...

In the title compound, the de-hydro-dipeptide (Boc-Phe-ΔAla-OiPr, C20H28N2O5), the mol-ecule has a trans conformation of the N-methyl-amide group. The geometry of the de-hydro-alanine moiety is to some extent different from those usually found in simple peptides, indicating conjugation between the H2C=C group and the peptide bond. The bond angles around de-hydro-alanine have unusually high valu...

BACKGROUND One of the considerable uses of lettuce (Lactuca sativa) seed in traditional medicine has been to reduce semen, sperm and sexuality. OBJECTIVE The aim of this study was to investigate the effects of aqueous and hydro-alcoholic extracts of lettuce seed on testosterone level and spermatogenesis. MATERIALS AND METHODS In this experimental study 24 adult male NMRI mice weighing 20-25...

Transition from fossil fuels to renewable sources is inevitable. In this direction, variation and intermittency of renewables can be integrated into the grid by means of hybrid systems which operate as a combination of alternative resources, energy storage and long distance transmission lines. In this study, we propose a two-stage stochastic mixed-integer programming model for sizing an integra...

In this paper, an artificial-based optimizes and analysis of an optimal proportional, integral, derivative (PID) controller is introduced for a hydro-turbine generator governor. The main purpose, optimization PID controller parameters of hydro-turbine connected to the network for damping output frequency oscillation. In The proposed approach, an optimal and evolutionary based proportional, inte...

An advanced operational semi-empirical algorithm for processing satellite remote sensing data in the visible region is described. Based on the Levenberg-Marquardt multivariate optimization procedure, the algorithm is developed for retrieving major water colour producing agents: chlorophyll-a, suspended minerals and dissolved organics. Two assurance units incorporated by the algorithm are intend...

The title compound {systematic name: (2S,3R)-ethyl 3-[(3aS,4R,6S,6aS)-6-tert-butyl-dimethyl-silyl-oxy-2,2-dimethyl-per-hydro-furo[3,4-d][1,3]dioxol-4-yl]-2-nitro-3-[(S)-tetra-hydro-2H-pyran-2-yl-oxy]propanoate}, C(23)H(41)NO(10)Si, is the product of the Henry reaction of 1-O-tert-butyl-dimethyl-silyl-2,3-O-isopropyl-idene-α-d-lyxo-penta-dialdo-1,4-furan-ose with ethyl nitro-acetate and the subs...

This paper describes the design and development of pico-hydro generation system using consuming water distributed to houses. Water flow in the domestic pipes has kinetic energy that potential to generate electricity for energy storage purposes in addition to the routine activities such as laundry, cook and bathe. The inherent water pressure and flow inside the pipe from utility’s main tank that...
