Abstract: The low order faults lead the oil-water relationship of oil-bearing block reservoirs complicated, especially in those blocks that show poor continuity of single sand spatial distribution and obvious heterogeneity of sand internal structure. The recognition of low order faults plays an important role in finding favorable well location and solving injection contradictions. Based on a single anticlinal structure of Wei 21 Block in Weixing oil field, this article investigates and analyses the relative variation trend of Putaohua top location reflected in the well information of named well line by using the dense well pattern material of Putaohua reservoir group, and achieves the goal of low order fault recognition in this block effectively in conjunction with seismic profiles, so as to provide foundations in designing interspaced well project.

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.

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: 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: Big emotion well oilfield is located in the southern songliao basin in the central depression area in the middle of the changling sag, is the jilin oil field.

Abstract: Evaluation of reservoir lithology recognition technology, is the foundation of reservoir and the reservoir comprehensive evaluation, and its precision directly affects the effect of reservoir evaluation, determine the level of fluid identification, capacity evaluation and precision. Portugal's west oil field, the black temple putaohua reservoir sedimentary environment is complex, because of its sedimentary environments and different hydrodynamic conditions, cause different sand body on the rock constituents, lithology involving powder sandstone and argillaceous siltstone, silty mudstone, mudstone, etc. Based on Portugal's west oil, the black temple putaohua oil layer in the particularity of geographic, sedimentary environment, cannot copy and paraphrasing from other parts of the existing interpretation result. In the understanding of the black temple, putaohua reservoir characteristics on the basis of sedimentary environment and establish corresponding relations between logging data and rock lithology lithologic identification methods should be a more suitable research train of thought.

Hypertension recognized as silent killer, has strong relationship with hormones secreted by endocrine glands. Present study was carried out to access the level of estradiol and testosterone in male and female cardiovascular hypertensive patients and to affirm their relation with hypertension. Serum samples of Cardiovascular hypertensive patients were tested for the level of estradiol and testosterone. Male and female cardiovascular patients were recruited for this study who were having treatment in District Head Quarter hospital. Estradiol level was significantly higher (61.38pg/ml; P=0.000) in post-menopausal hypertensive females, while normal concentration (51.01pg/ml; P=0.351) was observed in ovulating hypertensive females. In cardiovascular hypertensive males elevated estradiol level (51.545pg/ml; P=0.004) was found. Level of testosterone was higher (4.509ng/ml; P=0.000) in post-menopausal hypertensive females. Testosterone level was also raised significantly (4ng/ml; P=0.000) in hypertensive females that were in ovulating phase. We observed low level of testosterone (P=0.020) in cardiovascular hypertensive males. The level of the reproductive hormones was not normal range in females and males cardiovascular hypertensive patients. Level of the testosterone was lower in males suffering from hypertension while raised in female hypertensive patients that can lead towards problems in their marital life.

Medical students are the future health professionals and are expected to be teachers of hygiene as well as role models of self-care regimens for their patients. The objective was to assess self-reported oral health attitude and behavior among undergraduate medical students. A self-administered questionnaire based on the Hiroshima University-Dental Behavioral Inventory (HU‑DBI) was distributed among 421 undergraduate medical students which consisted of 20 dichotomous responses (Agree- Disagree). Data were analyzed. Mean HU‑DBI scores among nursing students is 5.62 (Average) which shows students have average attitudes towards oral health. This study did not show any statistical difference between male and female students (p>0.05). Furthermore, second, third and final year students had better oral health attitude and behavior especially towards gingival health, oral hygiene practices and visiting the dentist.

Mixed dentition space analysis is very important in orthodontic diagnosis and treatment planning. The present study evaluated prediction methods for the estimation of size of unerupted canine & premolars, and observed any sexual dimorphism in tooth size in a local population. A cross-sectional study was conducted on 192 boys and 192 girls aged 13-15 years who met the inclusion /exclusion criteria from schools of Lahore, Pakistan. Dental impressions of both arches were made and mesiodistal widths of teeth were measured with digital vernier caliper. Students t-test, Pearson correlation coefficient analysis and simple linear regression analysis was used to statistically compare tooth size differences in arches, among genders and predict maxillary and mandibular canine and premolars width based on sum of four mandibular incisors; sum of mandibular incisors and first molar; and sum of mandibular incisors and maxillary first molar. New regression equation was formulated for each arch and sex separately based on sum of mandibular incisors and maxillary first molar. Sum of maxillary first molar and mandibular incisors showed high correlation and determination coefficient in prediction of size of unerupted canine and premolars in the study population. Significant gender difference was found in tooth size in this sample. Sum of mandibular incisors and maxillary first molar is the better predictor for estimation of size of unerupted canine and premolars in our study population. Proposed prediction equations showed good accuracy, easy application and can be used in orthodontic treatment planning in local population.

Changes in today’s manufacturing environment allow tedious, fatiguing and repetitive tasks to be mechanically performed by robots, as manually controlled work is transition to auto-cycle control equipment. Such changes tend to take advantage of, and expand upon, operator process knowledge. As this trend continuous, the operator’s contribution becomes more technically oriented and less physically oriented with significantly greater product output being release. A robot is a reprogrammable multifunctional manipulator designed to move material parts, tools or specialized devices through variable programmed motions for the performance of variety of tasks. The step by step control and feedback is provided by a computer program run on either an external or embedded computer or a microcontroller.
