The basic characteristics of basalt fiber Basalt fiber is basalts as raw materials, and made by high temperature melting processing of fibers.
Obviously, basalt fiber has the basic conditions of being a kind of environmental materials by means of analyzing its properties.
Owing to its low purification ability, the nature water body needs biological materials to provide spaces for microorganisms animals to inhabit more than urban sewage treatment.
Materials Based on Basalts from the European North of Russia.
Review Science & Technology.

In biofuel production, the raw materials commonly used are vegetable oils.
Experimental Method Materials.
The resulting materials denoted as 0.5M SZ, 1.0M SZ, and 1.5M SZ.
The materials obtained were labeled 1% NiMo-SZ, 2% NiMo-SZ and 3% NiMo-SZ.
The materials were then put into an autoclave and heated at 110 ºC for 5 h.

Lignocellulosic biomass is a renewable source for sustainable production of fuels, chemicals, and other materials with the advantages on its carbon-neutral nature.
Fractionation of lignocellulosic materials is a pre-requisite in the biorefinery process in order to convert the cellulose, hemicellulose, and lignin to valuable products with maximized economics prospective.
A conversion of cellulose and hemicellulose materials into fermentable sugars is an important step because these fermentable sugars extracted from biomass feedstock play an important role for further conversion to biofuel and other biorefinery products.
The lignin content accounts for (24.64%) of dried materials.

Research on Scene Organize Algorithm Based on BVH with Dynamic Rendering Tree Li XU1,a, Maozhen LIU2,b 1 Computer College, Beijing Information Science and Technology University, Beijing 100101, China 2 Virtual Reality and Simulation Laboratory, Beijing Information Science & Technology University, Beijing 100192, China aemail:xuli_lh@139.com, bemail:liumaozhen123@126.com KEYWORDS：Scene Organize; Multimedia Technology; Rendering Tree; Scene Management ABSTRACT: The real-time rendering of 3D scene need excellent algorithm to support scene management.
For example, suppose there is such a scene, in a room with three computers on three desks respectively, two material cabinets, three chairs, for such scenes, we can organize the structure of the scene through the following steps: first, to determine the object in the scene, computer, desk, chair, material cabinet; then determine their relationships, material cabinet and chairs can be regarded as independent that can be drawn, with independent bounding box to represent the object's bounding volume, the computer on the desk, we can put a desk and the corresponding computer to be surrounded in the body, desk and computer in separate surrounded in the body, similar to the other two desks and computers; finally, determine the hierarchy, according to the three branches under the root node, respectively organize material cabinets, chairs, desk, computer, but computer and desk is divided into two branches, respectively is a desk and a computer.
