the selection of a growing medium is one of the most important decisions in the culture of hydroponic crops. in order to select a suitable medium for hydroponic cucumber (cucumis sativus l. cv. negin), an experiment was carried out on growing media containing different particle sizes of perlite and organic substrates in a run-to-waste system in a greenhouse experiment. the growing media tested ...

agaricus bisporus is the most important industrially cultivated edible mushroom. using organic wastes as substrate for cultivation of edible mushroom can provide a perfect solution for disposal of these waste materials and is part of the world's food requirements .in this study to investigate the usability of various organic wastes as growing bed for button mushroom, four types of substrat...

A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...

In this work, Poly(ethyleneterephthalate) (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing PCL )polycaprolactone( as organic phase and TEOS )tetraethoxysilane( as inorganic phase. The coating was prepared through a sol-gel process and applied on the surface by dip coater. Then, electrically conducting polythiophene (PTh) nanoparticles were depo...

During this project the research focused on the following topics: a) the development of a MEMS reconfigurable Sierpinski antenna on LCP substrate; b) the development of a low cost localized packaging technique for RF MEMS switches integrated on a multilayer organic substrate (this is extremely important for the switch reliability that will be required in the reconfigurable antenna system); c) t...

the effect of three levels of eucalyptus leaf (0, 28.65 or 57.37mg/200mg substrate), which were either oven, freeze or air dried on in vitro ruminal fermentation characteristics was assessed. the studied parameters were in vitro gas production (ivgp), methane production, ammonia (nh3-n) concentration, in vitro organic matter degradability, partitioning factor (pf) (ratio of substrate truly degr...

Paper mill effluent (PME) was used as an organic feedstock for production of biohydrogen via dark fermentation using heat-shock pretreated anaerobic sludge under mesophilic conditions. The influence of substrate concentration (5, 10 and 15 g-COD/L) and the initial pH (5 and 7) on the efficiency of dark hydrogen fermentation from PME were investigated. The highest hydrogen yield of 55.4 mL/g-COD...

the aim of this study was to investigate the fermentation characteristics and cellulolytic enzymes activities of dromedary camels rumen anaerobic fungi in fed with cultivated and pasture forages. hence, the inoculant of rumen anaerobic fungi was prepared by using specific medium and the gas production, digestibility and enzyme activity of rumen fungi were determined on the basis of a 2 × 2 fact...
