Gas Hure Oilfield is the biggest one in the Qaidam Basin. Through intensive sampling and GC-MS a- nalysis, the authors analyzed the geochemical characteristics of the crude oils in the Gas Hure Oilfield. The re- sults show that the crude oils have even-odd carbon predominance for n-alkanes. In shallow reservoir, part of crude oils suffered biogenic degradation. As for normal oils, they have low Pr/Ph ratios with abundant gammac- erane and C35 homohopane, which indicate that the crude oils are formed in strong reducing salt water environ- ment. Compared deep （ E~ ） reservoir with shallow （ N1 - N2^1 ） reservoir, the ancient salinity of sedimentary en- vironment of Nj-N1 crude oils is slightly higher than that of E3^1crude oils; the C21-/C22＋ ratios of crude oils are 1.02-1.71 with a higher abundance of C27sterane, which shows that their mainly origin matrix are bacteria and algae; the C29 sterane 20S/（20S ＋ 20R）is generally low, the ratio in deep E3^1 reservoir distributes between 0.31 and 0. 40, but in shallow reservoir is relatively low with 0. 29-0. 36. At the same time, C29sterane αββ（αββ ＋ααα） and Ts/Tm both are extremely lower. All the above show that the crude oils in Gas Hure are mainly low mature oils, although the maturity of deep reservoir crude oils is slightly higher than shallow one.

Groundwater is the main resource for human consumption in many countries, especially in developing countries. This groundwater is often brackish and hyperfluorinated, which leads to diseases such as dental and bone fluorosis, etc. The water from the Diouroup water drainage facilities, like those from many other water drainage facilities in the regions of Fatick, Kaolack, Diourbel and the area of Touba, is facing this problem. To solve these problems, several physicochemical and membrane methods have been implemented. In this work we have briefly outlined some of these methods and we have chosen one of them, low pressure reverse osmosis. In addition, this technique is very simple to operate and maintain. Reverse osmosis provides good quality water in a single step, without the need for additional sterilization or remineralization treatments. We then carried out simulations with the Reverse Osmosis System Analysis (ROSA) software. For reasonable operating parameters, we have noticed a low feed pressure of 11.58 bars, a good average flow of raw water of 27.79 L/m2/h and a recovery rate of the first pass of 75.01%. The results obtained also showed a good quality of the permeate which respects the recommendations of the World Health Organization (WHO) on drinking water. The fluorides of 0.59 mg/L have a recovery rate of 90.8% while the chlorides of 59.09 mg/L have a recovery rate of 92.12% as for the Total Dissolved Solids of 184.90 mg/L for an abatement of 92%. Finally, the low energy consumption of the process makes it possible to consider it in coupling with an electric supply by photovoltaic solar collectors for isolated sites.

Terms of intelligence in 20th and 21th century mean the methods of automatic extraction, analysis, interpretation and use of information. Thus, the intelligence services in the future created an electronic database in which to their being classified intelligence products, users could choose between the latter themselves relevant information. The EU （European Union） that activities are carried out from at least in year 1996, terrorist attacks in year 200l is only accelerating. Proposals to increase surveillance and international cooperation in this field have been drawn up before September 11 2011. On the Web you can fmd a list of networks （Cryptome, 2011）, which could be connected, or are under the control of the security service--NSA （National Security Agency）. United States of America in year 1994 enacted a law for telephone communication--Digital Telephony Act, which would require manufacturers of telecommunications equipment, leaving some security holes for control. In addition, we monitor the Internet and large corporations. The example of the United States of America in this action reveals the organization for electronic freedoms against a telecom company that the NSA illegally gains access to data on information technology users and Internet telephony.

The aim of this paper is to estimate the direct solar radiation on a horizontal plane in five regions of Chad using the Liu and Jordan’s model in view of the installation of a thermo-solar power plant. For this purpose, the HelioClim-3 Data Base of Solar Irradiance V5’s is used. All the results presented in this paper were obtained using Microsoft Excel software 2015. These results show that compared to the other regions considered for this study, the direct solar radiation on a horizontal plane in Moundou is less.
