Abstract: In this study, we used the concept “didactical contract”, which was introduced by Guy Brousseau in 1980, as a tool for finding out the errors of students. In order to illustrate this approach, we used the type of a task: “In the space Oxyz, write the general equation of a plane (P) passing through point A(x0, y0, z0) and parallel to two straight lines: (d1) and (d2) ((d1) and (d2) are not parallel to each other)” which was mentioned in mathematics textbooks of Vietnam. We formulated the hypothesis H: there exists a rule of didactical contract: When solving the problem, students don’t verify whether (d1) and (d2) are parallel or not; therefore, students will commit errors in the case of (d1) and (d2) are parallel. The results of study showed that many students committed errors in solving the exercise because of the above didactical contract.

Abstract: The relative effectiveness of Information Communication Technology (ICT) and its consequences in this fast-changing world was endless. This paper investigates mobile phone, It usage, proficiency and it’s constrain in Nigeria. Global System for Mobile Communication (GSM) has brought tremendous changes in individual way of life and societies in general where people who stay far from one another can easily link together with wireless phone. A mobile phone also called mobile cellular telephone, or cell phone can be regarded as an electronic device used for two-way radio telecommunication over a cellular network of base stations known as cell sites. Most mobile phones provide voice communications, Short Message Service (SMS), Multimedia Message Service (MMS), and provide Internet services such as Web browsing and email etc. It promotes significant benefit to education, business transaction and social life in general. While on the other hand it contributed a lot toward spreading anti-social act, immorality and ill health to some extent etc. An official statistic by Nigerian Communication Commission (NCC) revealed that there are about 150,660,631 active mobile phone connections in Nigeria as at the end of third quarter 2015. Uses of mobile phone good or bad are two side of a coin. Every good thing when abuse can be harmful, so it is with mobile phone. Minimizing the amount of time spent using mobile phone, speaker mode use or a headset use and public awareness on proper cell phone use pattern would help toward having optimally benefited from having mobile phone.

Abstract: Management of the nasal tip is the most challenging step in rhinoplasty. Control over nasal tip projection is essential. A variety of techniques can be used to improve the position of nasal tip. The aim of the present study was to compare the changes of nasal tip between a novel tip plasty technique and the conventional sheen graft one. In this clinical trial study, 60 patients referring for rhinoplasty to the Department of Oral and Maxillofacial Surgery, Tabriz University of Medical Sciences, were included. The subjects were randomly divided in two groups: a new tip plasty technique was used for the first group and the conventional sheen graft technique for the second group. The nasal tip changes were compared between them. The means of tip projection were 28.92±4.16 and 26.95±7.30 preoperatively in groups A and B, and they were 33.00±3.86 and 31.29±6.35 after surgery, respectively, with no significant differences in between. The means of tip rotation before surgery were 114.10±7.53 and 113.08±9.94 in groups A and B, while these figures after surgery were 119.46±7.21 and 117.58±8.92, respectively. The new technique is as effective as conventional technique in improving nasal tip. Although the new technique of rhinoplasty is much easier.

Sinian system in the basin is one of the oldest hydrocarbon-bearing series also the earliest series found large gas reservoir (weyuan gas reservoir). As we known, the sinian system in the bottom of sichuan basin which formed long time ago and buried depth. The ancient hydrocarbon bearing serie experienced polycyclic tectonic movement .How to impact of sinian system Oil and gas geological conditions in deep basin by all previous tectonic movement that is the key to the evaluation of the oil and gas resource potential. Based upon this, I am from the perspective of tectonic evolution to to discussing the different tectonic movement how to influence the oil and gas accumulation conditions of sinian system, and meanwhile discuss about hydrocarbon source condition, reservoir condition and oil and gas accumulation and enrichment how to impact hydrocarbon accumulation, and then points out that where is the sinian system favorable zones for oil and gas exploration.

Abstract: The unconventional tight reservoir has experienced multiple geological processes, the types of reservoir are varied, the shape and size are different, the distribution is discrete, and the lithology is complex, resulting that the conventional modeling can’t effectively solve the problem of the unconventional tight reservoir. Taking the characteristics of different scale pore, complex nature/ artificial fracture network in unconventional tight reservoir into consideration, this paper proposes a method that taking the characterization of micro-pore texture of unconventional tight sandstone and the techniques for identification and description of natural/ artificial fractures as basis, and contains the modeling of different scale pore and complex nature/ artificial fracture network. This method is mainly divided into 4 aspects, firstly, based on mercury injection data, the pore type reservoir is divided into 4 stages, and stochastic simulating the matrix reservoir distribution model controlled by sedimentary model; secondly, taking seismic data as basis, combined with advanced techniques such as ant-body, deterministic simulating the large scale natural discrete fractures networks controlled by human computer interaction; thirdly, according to the medium-small scale fractures by logging data and micro scale fractures by casting lamella data, calculating the fracture intensity curve, simulating the medium-small and micro scale discrete fracture networks by stochastic algorithm; finally, based on micro seismic data, simulating the different scale artificial fractures by combining the stochastic and deterministic algorithm. This paper take the upper sweet-point of development pilot area in Changji oilfield which is in Lucaogou Formation of Junggar Basin of Xinjiang as example, establishing the model of tight reservoir by the method above, highlight the characteristics of tight reservoir, providing the static model of multi-medium reservoir with high precision to numerical simulation.
