ultra-endurance mountain running has become extremely popular in recent years, and the energy cost is one of the factors that influence the final performance. the aim of this study was to determine if the energy cost of uphill running (uphill cr) can be calculated from level cr (energy cost of running in mlo2.kg-1.mn-1) in a heterogeneous group of mountain ultra-endurance runners using the di p...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
• Multiple configurations of VPP aggregating CCHP and Solar PV are assessed. New profit maximization objective function is presented for regulated markets Optimization solved with GA simulating different system sizes. The propsoed method improved the cost energy reduced grid dependency This paper investigates design operation management VPPs in markets. A new framework based on this study. hypo...
Hybrid power systems based on new and renewable energy sources, especially photovoltaic and wind energy, are an effective option to solve the power-supply problem for remote and isolated areas far from the grids. Microsoft Excel software programming package is used to analyze data measurements for both wind and solar radiation measurements for the two locations in Palestine (Ramallah and Nablus...
The optimal planning of grid-connected microgrids (MGs) has been extensively studied in recent years. While most the previous studies have used fixed or time-of-use (TOU) prices for sizing MGs, this work introduces real-time pricing (RTP) implementing a demand response (DR) program according to national grid Iran. In addition long-term MG, day-ahead operation MG is also analyzed get better unde...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
In this study, a standalone hybrid wind turbine (WT)/photovoltaic (PV)/biomass/pump-hydro-storage energy system was designed and optimized based on technical, economic, environmental parameters to provide the load demand with an objective function of minimum cost (COE). The constraints proposed approach are loss power supply probability, excess fraction. allows combination different sources bes...
Isotropic sa mples of Barium Ferrite are prepared by coprecipit a tion method. To study the effect of sintering temperature on magnetic propeTl ies of Barium ferrite we have sintered the samples in diUerent temperature from 900 up to J 100°C. Mean partieal size and porosity of the samples are dete rmind by scanning electron miecroseop (SEM), magnetic phase and magnetic parameters are meas...
Water irrigation systems (WISs) are an important factor for agricultural development and food security. However, their energy supply is affected by several problems related to the use of diesel generators, especially in remote areas. This paper describes a new methodology used design cost-effective sustainable solution provide water system with demand 40 kWh/day. A combined side management (SSM...
World population growth and increased energy demand are taking a heavy toll on the environment. Aside from developed countries, adverse effects far more apparent in third-world which also affected by climate change, pollution, fuel scarcity. One of primary solutions to this challenge is implementation cleaner sustainable resources. Building scale renewable integration one included hybrid system...
