Ways and Countermeasures to the Ecological Development of Mineral Resources Industries in West China
Online since: October 2014
Authors: Shao Hong Cai, Wen Jiang Liu, Qiu Lan Xiang, Yang Lu
In the western area, ecological environment is fragile, and mining-induced secondary geological disasters exacerbate the deterioration of ecological environment; the damages caused by mining activities on the water balance system and the pollution caused by the “Three Wastes” from the mineral industries lead to vegetation, soil erosion, desertification, atmospheric water pollution and the degradation of the ecological environment; disordered mining construction, excavation of ore and waste rock dumps, not only destroy the landscape, tying arable land, the losses of water and soil resources are also exacerbated.
Because of its clustering features as geographic concentration, mutualism, cooperative and competitive, flexible, professional, etc., as well as its following competitive advantages: operating costs, technological innovation, resources allocation, collaboration, etc., it has been considered as an efficient industrial organization model in terms of economic benefits.

Each sample was made by diluting S-64 with appropriate amounts of water.
The details of the acid removed and water added in each cycle are shown in Table 3.

As water is being removed from the acid during evaporation, to replace the lost water, dehydration of hydrogen peroxide by sulphuric acid will take place, giving rise to reactive oxygen species which oxidises any organic material to give carbon dioxide and water.

Test Method for Self-Cleaning Performance of Semiconductor Photocatalytic Materials - Measurement of Water Contact Angle (ISO 27448: 2009).
It is asserted that by applying this method the decomposition of organic substance and change of water affiliation can be properly evaluated [3].
The CA, θ, made by a water droplet is then measured at 5 different points in the sample before and during irradiation.
During illumination, samples for analyses are obtained by washing the TPA layer with a mixture of ethanol/water solution (0.25 mL/cm2).
Self-cleaning activities determined by measurements of water contact angle (WCA) (left) and by TPA method (right).

Secondly, the ortho-rectification of TM images should be done based on Control Point by using the module of Image Geometric Correction of ERDAS IMAGINE 9.1, a Professional Software of Remote Sensing Image Processing.
Information extraction from the Remote Sensing images The Information Extraction from the Remote Sensing images is the processing of obtaining the land cover type and the attributes of mangrove forests, farmland, forest, water, village habitation and town land by man-machine interactive mode
Its shape is mostly banding and plane with clear boundary and with the water system throughout.
(4) Remote Sensing analysis of water: including two types: river and pond.

The BCIRA Test principle
has been applied for purposes of designing a Polish professional DMA Device named by its
designers a device for testing the high-temperature phenomena in casting cores [6, 7].
The effect of free water contents and the water chemically bounded in inorganic resin SE on the growth of substitutional specific heat c is also clearly evident.
The sources exist until water evaporation from the sample.

Because there is no professional equipment and consumables for vacuum sealing method, the vacuum packaging machine in the food industry is used in this study.
The sealed specimen are submerged in the water, and then weigh the quality in the water; 5.
To remove the samples from the water, untied bags, reweighing specimens dry weight.

Abstract.
Parallel to this were the engineering requirement of developing a stronger general and specific vocabulary, written/oral English in active ways that integrated and generated ideas in technical areas (water, chemistry, biology and ecology etc).
Role-playing and simulation were very important and included: simulated professional teamwork, work related technical problem solving tasks and/or workplace situations in activities like Debating and Theater Forum (based on Experiential Learning).
Valentukeviciene is from the Water Supply and Management Department was the Project's Manager, Edita Baltrenait÷, is a Doctoral Student (Environment Protection Department) was the Project's Assistant Administrator.

Nowadays, water-logging in cities usually occurred in large recurrence interval, so that many experts suggest that annual maximum value method is more applicable.
It isnecessary to evaluate the storm intensity formula, It is reasonable that evaluating storm formula, original stormformula for whether itis still applicable for the overall design plan of the city, the drainage professional planning and drainage engineering.

The performance of the engine slightly outreached 35 kW and it was used as a drive for water pump.
Harrington used a steam engine with sunlight drive that drove a pump, and delivered water up to the height of 6 metres and filled the reservoir of 20 m3
Wilson created the device for the distillation of water with daily output of 22,500 litres on the area of 5000 m2
Specialized literature oriented on the field of experts for installation of photovoltaic systems draws attention to the use of highly professional tools when fitting the cable endings by a method of crimping them to the conductor.
