Tuberose is one of the most important aromatic cut flower among ornamental plants that its growth and quality is influenced by the type and percentage of mineral compounds in the substrate. This study was carried out on the basis of a randomized complete design to explore the impact of feldspar, talc, dolomite and tuff minerals at the rate of 10, 20 and 40% incorporated with garden soil and man...

This study is focused on the emission of fixed bed combustor batch operated. Real-time analyser ELPI (electrical low-pressure impactor) system was used to size-segregated particulate matter emission ranging from 40 nm to 10 μm. The results show that total number concentration were 3.4 × 10(3), 1.6 × 10(4), and 1.5 × 10(5) particles/cm(3) · kg(fuel), while total mass of particles were 12.2, 8.0,...

Consolidated bioprocess assures an efficient lignocellulosic conversion to fermentable sugars and subsequently to bioethanol. Such a single-step hydrolysis and anaerobic fermentation was achieved with acclimated Clostridium thermocellum DSM 1313 on different mildly pre-treated agricultural lignocellulosic residues without any additional enzymes/and strains. Acclimation was achieved by serially ...

Extruded pellets were made based on deoiled rice bran and paddy husk using glycerol and cashew nut shell liquid as plasticizer. Effects of incorporation levels of glycerol (GL, 6 to 14 %) and cashew nut shell liquid (CNSL, 6 to 14%) on the physical and functional characteristics of extruded pellets based on deoiled rice bran and paddy husk powders were studied. For A3 samples (12% GL) radial ex...

Most of the soil available for infrastructure development is not suitable construction. It a real challenge to overcome difficulties faced with problematic soil. We need get better experienced those soils. In India around The annual output RHA 31 million tons..It contains 85%-90% silica which pollutes environment and also causes health hazards.As it producing in large amount every year, there r...

Combustion characteristics of rice husk and coconut shell briquettes have been investigated with a view establishing its suitability as an energy source. The were collected carbonized in furnace charcoal (RHC) (CSC). These further down sized sieved to 2.5 mm particle size. RHC CSC mixed proportions 50:45, 60:35, 70:25, 80:15, 90:5% by weight respectively, 5% cassava starch used binder for all t...

Lateritic soil was treated with 0, 4, 8, 12 and 16% rice husk ash (RHA) by dry weight of to determine its consolidation properties. Test carried out include; particle size distribution, specific gravity, compaction test varying compactive efforts (British Standard Light (BSL), West African (WAS) as well British Heavy (BSH)) test. Samples for were compacted then cured 7, 28 56 days; subjected on...

In this study, we analyzed the operational characteristics of a 1.2-MW rice husk gasification and power generation plant located in Changxing, Zhejiang province, China. The influences of gasification temperature, equivalence ratio (ER), feeding rate and rice husk water content on the gasification characteristics in a fluidized bed gasifier were investigated. The axial temperature profile in the...

The potential of economically cheaper cellulose containing natural materials like rice husk was assessed for nickel adsorption from aqueous solutions. The effects of pH, contact time, sorbent dose, initial metal ion concentration and temperature on the uptake of nickel were studied in batch process. The removal of nickel was dependent on the physico-chemical characteristics of the adsorbent, ad...

this study was aimed to the examination of the effect of tillage row spacing and bush spacing on the performance and components of phaseou vulgaris var. (line: cos16). the investigation was conducted as cut terraces and in terms of complete random blocks in three replicates at brujerd agricultural research and natural resources in the agricultural year 2009-2010. here, the main terraces with th...
