Biogas refers to a gas, primarily of methane and carbon dioxide, produced by the anaerobic digestion or fermentation of biodegradable materials such as manure or sewage, municipal waste, energy crops etc in the absence of oxygen [2].
Biogas, a renewable energy carrier consisting mainly of methane (CH4) and carbon dioxide (CO2) and some traces such as hydrogen (H2), oxygen (O2) hydrogen sulfide (H2S), is the end-product of the anaerobic digestion of organic material [4,5].
The raw material for the biogas is from cow dung.

The types, manufacturing process and performances of optical fiber materials are mainly studied for meeting the demands of different network environments such as metropolitan area network, local area network, and network connection through relying on high-performance optical fiber.
(1) The quantity of information channels and the preparation of device interfaces should be redundant by about 20% based on actual conditions (2) Certain upgrade standard should be achieved by the equipments and optical cables in hidden project, so as to prevent repeated construction (3) The projects of prepared hole and wire should be constructed in strict accordance with relevant standards (4) The core equipment should be a technical level at least higher than the existing engineering requirement if capital is allowable (5) The materials about the final construction drawing, connecting device, and communication line parameters should be submitted and recorded in the acceptance of project, for making the subsequent investigation easy Conclusion Optical cable and its supporting products are various.

Introduction The reason of popularity of contemporary cable-stayed bridges among bridges can be attributed to: 1) the appealing aesthetics; 2) the full and efficient utilization of structural materials; 3) the increased stiffness comparing with suspension bridges; 4) the efficient and fast mode of construction; and 5) the relatively small size of the bridge elements [1].
This consideration leads to a reduction in the materials used in bridges and results in a decrease in the weight of bridges.

In regard to how to improve the management and science of the metro project, as well as strengthening the “objective management and process control", many scholars have done a lot of useful explorations.
The construction sites, on the one hand, need to deal with the existing traffic flow pressure, on the other hand, need to enclose construction sites and consider the entry and exist of construction machinery, materials, equipment, and personnel, which require the metro implementation process to separate the production supply of equipment and materials from used space.

The materials of expanding sleeve are usually spring steels of 65, 65Mn, 55Cr2, 60Cr2, etc [117].
In the meanwhile, the weight and cost would be increased, which is a waste of materials.

Methods 2.1 Biomass Sample The wood chip material obtained from furniture factory, with rubber wood as the main component was used for this study.
The carbon conversion efficiency presents the amount of carbon in the biomass material converted into gases shown in equation below.
Ash content (wt. %) for rice husk was slightly higher than those found in woody biomass materials.
