This paper reports the results on the use of an innovative inert, based on stabilized fly ash from municipal solid waste incineration as a filler for polypropylene. The starting material, which contains large quantities of leachable Pb and Zn, was stabilized by means of an innovative process using rice husk ash as a waste silica source, together with other fly ashes, such as coal fly ash and fl...

Many non-conventional adsorbent have been studied as economic alternative to commercial activated carbon and mostly agricultural waste have been introduced such as rubber leaf powder and hazelnut shell. Microwave Incinerated Rice Husk Ash (MIRHA), produced from the rice husk is one of the low-cost materials that were used as adsorbent of heavy metal. The aim of this research was to study the fe...

This study evaluated the kinetic adsorption of Pb and Cu ions using rice husk ash as adsorbent in a fixed bed. The maximum adsorption capacities obtained for lead and copper ions in the fixed bed were 0.0561 and 0.0682 mmol/g (at 20 °C), respectively. The thermodynamic studies indicated that the lead adsorption process was exothermic and spontaneous, while the copper adsorption process was endo...

Because grain shape is an important component of rice grain yield, the discovery of genes related to rice grain shape has attracted much attention of rice breeding programs. In recent years, some of these genes have been cloned and studied. They have been found not only regulate grain shape by changing the shape of the spikelet hull, but also regulate endosperm development through control of ce...

Today concrete is most widely used construction material due to its good compressive strengt h and durability. Depending upon the nature of work the cement, fine aggregate, coarse aggregate and water are mixed in specific proportions to produce plain concrete. Plain concrete needs congenial atmosphere by providing moisture for a minimum period of 28 days for good hydration and to attain desired...

The study was conducted at Dr. Emilio B. Espinosa, Sr. Memorial State College of Agriculture and Technology (DEBESMSCAT) Cabitan, Mandaon, Masbate. experimental design used 3 x 7 CRD factorial with three varieties mushrooms (Pink Oyster, White Abalone, Milky Mushroom), seven agricultural substrates as treatments, Treatment A (70% rice straw 30% sawdust), B corn cob), C Carbonized Rice Hull), D ...

As concrete is still one of the most used in construction,developmenton improving its strength andpossible reduced environment impactis necessary.This study determines mechanical properties with addition recycled High-Density Polyethylene (HDPE) Macro Flat Fiber (MFF) and Rice Hull Ash(RHA) as partial replacement to cement. The objective this identify theoptimum mix ratio for compressive flexur...
