Influence of Perforation on Formation Fracturing Pressure

Hydraulic fracturing treatments of oil wells are greatly affected by the perforation parameters selected. The three-dimensional finite element model together with the tensile criterion of rock materials is employed to systematically investigate the influence of perforation parameters, such as perforation density, perforation orientation, perforation diameter, and perforation length as well as wellbore ellipticity, in vertical wells on the formation fracturing pressure. Based on a six-month simulation research in the University of Petroleum, China, several conclusions are drawn for the first time. Perforation density and perforation orientation angle are the most important parameters controlling the formation fracturing pressure. As the perforation density increases, the fracturing pressure decreases, not linearly but progressively. The fracturing pressure increases with the perforation orientation angle only when the angle is less than 45 degrees, and the relationship becomes very flat when the angle is 45 degrees. However, with regards to the perforation diameter and perforation length, their influences are much slighter. The wellbore ellipticity has a significant effect on the formation fracturing pressure. It is obvious that fracturing pressure increases linearly with the ellipticity of the wellbore.

Preparation and evaluation of ophthalmic thermosensitive in situ gels of penciclovir

Aim To develop pluronic F127 （PF127） based formulations of penciclovir （PCV） aimed at enhancing its ocular bioavailability. Methods Thermosensitive in situ gels of penciclovir were prepared through combination of HPMC K4M or carbopol 934P and pluronic F127. Optimized formulations were examined through measuring gelation temperature, rheology speciality, drug release behavior, pharmacokinetics and ocular irritation. Results The gelation temperature was reduced by adding HPMC K4M or carbopol 934P, and the viscosity was enhanced slightly. Either HPMC K4M or carbopol 934P delayed the release of PCV from in situ gel. PCV was released by non-Fickian diffusion. The study of ocular irritation for different PCV formulations did not show any irritation or damage for the cornea. PCV bioavailability from combination of carbopol 934P and pluronic F127 gels was higher than that obtained from any other gels. Conclusion Pluronic F127 formulations of PCV can be used as liquid for administration by instilling into the eye. Facilitated by the appropriate eye temperature, the formulations were transformed to gel phase. On the basis of in vitro and in vivo results, PCV formulations containing HPMC K4M or carbopol 934P and low concentration of pluronic F127 （12%） showed potential for use as a drug delivery system with improved ocular bioavailability.

Study on Drug Resistance and Relative Mechanisms of Chlamydia Trachomatis

Chlamydia Trachomatis (C.T.) is one of the most common pathogens of human sexually transmitted diseases. Treatment of C.T. infection primarily depends on Tetracyclines, Macrolides and Quinolones, but with the wide use of antibiotics an increasing number of drug-resistant Chlamydia trachomatis cases have been reported. This review summarizes the resistant conditions and the possible resistance mechanisms of C.T..

Clinical investigation of surgery for intermittent exotropia

Objective： To investigate the time and postoperative binocular vision of strabismus surgery for children with intermittent exotropia （X（T））. Methods： A retrospective investigation was conducted in 80 child patients with intermittent exotropia. Pre- and postoperative angles of deviation fixating at near （33 cm） and distant targets （6 m） were measured with the prolonged alternate cover testing. The binocular function was assessed with synoptophore. Twenty-one patients took the postoperative synoptophore exercise. Results： （1） A week after surgery, 96.2% of the 80 patients had binocular normotopia, while a year after surgery, 91.3% of the 80 patients had binocular normotopia; （2） Preoperatively, 58 patients had near stereoacuity, while postoperatively, 72 patients achieved near stereoacuity （P〈0.05）; （3） Preoperatively, 64 patients had Grade Ⅰ for the synoptophore evaluation and postoperatively, 76 patients achieved Grade Ⅰ. Meanwhile, 55 patients had Grade Ⅱ preoperatively and 72 achieved Grade Ⅱ postoperatively. For Grade Ⅲ, there were 49 patients preoperatively and 64 patients postoperatively （P〈0.05）; （4） Patients of 5-8 years old had a significantly better recovery rate of binocular vision than those of 9-18 years old （P〈0.05）; （5） Patients taking postoperative synoptophore exercise had a better binocular vision than those taking no exercise （P〈0.05）. Conclusions： （1） Strabismus surgery can help to preserve or restore the binocular vision for intermittent exotropia; （2） Receiving the surgery at young ages may develop better postoperative binocular vision; （3） The postoperative synoptophore exercise can help to restore the binocular vision.

Comparing the reinforcement capacity of welded steel mesh and a thin spray-on liner using large scale laboratory tests

Steel mesh is used as a passive skin confinement medium to supplement the active support provided by rock bolts for roof and rib control in underground coal mines. Thin spray-on liners(TSL) are believed to have the potential to take the place of steel mesh as the skin confinement medium in underground mines.To confirm this belief, large scale laboratory experiments were conducted to compare the behaviour of welded steel mesh and a TSL, when used in conjunction with rock bolts, in reinforcing strata with weak bedding planes and strata prone to guttering, two common rock conditions which exist in coal mines. It was found that while the peak load taken by the simulated rock mass with weak bedding planes acting as the control sample(no skin confinement) was 2494 kN, the corresponding value of the sample with 5 mm thick TSL reinforcement reached 2856 kN. The peak load of the steel mesh reinforced sample was only2321 kN, but this was attributed to the fact that one of the rock bolts broke during the test. The TSL reinforced sample had a similar post-yield behaviour as the steel mesh reinforced one. The results of the large scale guttering test indicated that a TSL is better than steel mesh in restricting rock movement and thus inhibiting the formation of gutters in the roof.

On the Possibility to Construct Gravitational Eye

The possibility of modifying a conventional Cavendish torsion pendulum into a half-armed pendulum oscillator to measure the horizontal gravitational acceleration is discussed. A new kind of gravitational detector, gravieye, as we named, can be made by a proper combination of such oscillators to ＂see＂ remote objects and to be used, e.g. to detect the movement of huge mass at a long distance.

Environment map building and localization for robot navigation based on image sequences

SLAM is one of the most important components in robot navigation. A SLAM algorithm based on image sequences captured by a single digital camera is proposed in this paper. By this algorithm, SIFT feature points are selected and matched between image pairs sequentially. After three images have been captured, the environment’s 3D map and the camera’s positions are initialized based on matched feature points and intrinsic parameters of the camera. A robust method is applied to estimate the position and orientation of the camera in the forthcoming images. Finally, a robust adaptive bundle adjustment algorithm is adopted to optimize the environment’s 3D map and the camera’s positions simultaneously. Results of quantitative and qualitative experiments show that our algorithm can reconstruct the environment and localize the camera accurately and efficiently.

Television Sports News Between Performance, Violence and Spectacle

The purpose of this paper is to analyze today＇s construction of sports news, and to see the way that media present the live sports events and how do livc sports events become global breaking news. We started with the theoretical background and we analyzed the audiences of the TV channels dedicated to sports. Media and violence is a well-known subject, and many theorists have analysed it but little research has been conducted about the effects that violence in sport news may have on people or society. Therefore, the aim of this study is to provide insights into these effects, to try to demonstrate that today＇s sports news does not focus on pcrformancc any more, but they have become a spectacle of violence and gossip. After reviewing the literature in order to gain a perspective on this topic, we focused on the complex reconstructive and subjective nature of news rcception, the different ways the audience constructs meaningful intcrpretations from the news, exposure to news and the construction of violent images of reality.

Numerical computation algorithm of explosion equations and thermodynamics parameters of mine explosives

A new numerical algorithm is presented to simulate the explosion reaction process of mine explosives based on the equation of state, the equation of mass conservation and thermodynamics balance equation of explosion products. With the affection of reversible reaction of explosion products to explosion reaction equations and thermodynamics parameters considered, the computer program has been developed. The computation values show that computer simulation results are identical with the testing ones.

A Method to Measure Eye-Hand Coordination for Extracting Skilled Elements-Simultaneous Measurement of Eye-Gaze and Hand Location-

The purpose of this study was to construct bases for exploring the process of skill acquisition from the viewpoint of eye-hand coordination. The information obtained from eye-gaze is closely related to physical movements in any activity. It is important to establish a method to measure eye-hand coordination for extracting skilled elements and understanding the skill acquisition process. Using a system which consists of an eye mark recorder and a three-dimensional location measurement device, a method for measuring eye-hand coordination was proposed on the basis of the simultaneous measurement of eye-gaze and brush tip locations. After describing the measurement algorithm, the eye-hand coordination during calligraphy was exemplified. More concretely, using such a system, an attempt was made to show that the relationship between the line of eye-gaze and the brush tip stroke was different between a novice and an expert. In such a way, we suggested that the proposed method is promising for exploring the process of skill acquisition.

The Blind Spot of the Sovereign Eye： On the Gaze in Merleau-Ponty and Lacan

In this essay I will explicate the gaze （le regard） and the ways in which it exceeds or transcends what we know as vision, the objectifying or representational power of the eyes. Building critically on Sartre, the gaze in Lacan and Merleau-Ponty is part of the technical apparatus used to describe the foundation, production, and reproduction of the subject. I will begin by discussing the role of visual perception in subject-formation in their respective work, differentiating between the Merleau-Pontian notion of the ＂gaze of the world,＂ i.e., the ways in which things cast their gaze upon us, and the Lacanian gaze as a manifestation of the scopic drive. Through an analysis of anamorphosis I will show （1） how the gaze evades the spectator, （2） what the relationship of the gaze is to the object petit a as the object of the scopic drive, and （3） how both Merleau-Ponty and Lacan require a movement that precedes and destabilizes the subject of intentional consciousness.

Physical Concept of Human Eye

This article describes model of human eye fluctuations such as refraction etc. and makes its physical interpretation. Because mistakes in refraction measurements correspond to fluctuations in eye＇s focus, it is possible to calculate theoretical limits for the best accuracy in measurements of eye＇s refraction （0.25-0.3 D）. Optical model for astigmatic human eye predicts possibility only 70% compensation of visual acuity by cylindrical glasses. New data and methods for digital measuring of color and gray vision were tested, too. Also ,some new results and model for periphery color and grey vision were proposed and discussed.

Land＇s Prior Use Affects the Establishment and Productivity of Rabbiteye Blueberry （Vaccinium ashel~ Cultivars

＂Austin＂ and ＂Climax＂ rabbiteye blueberries （Vaccinium ashei） grown on two soil types in Columbia, AL were studied during 2009-2010 to evaluate the effect of soil quality on blueberry vegetative growth, yield, and fruit characteristics. The site previously used for peanut production had 2% organic matter, a high soil pH, and a high phosphorus level, while the site previously left to pasture had twice as much organic matter, lower pH and phosphorus. Both cultivars had greater fruit set when grown on pasture land in comparison to the same cultivars grown on old crop land. Pasture land grown ＂Austin＂ and ＂Climax＂ plants produced as much as three times greater yields than the same cultivars grown on old crop land, and were more vigorous in comparison with plants grown on old crop land. Higher plant vigor and yields may be a result of the alleviation of establishment stress provided by the higher organic content found on the pasture land soil. Proper soil amendment prior to planting may serve to improve some of the differences in rabbiteye blueberry plant performance during the years of establishment.

The Effect of Water Hyacinth （Eichhornia Crassipes） Infestation on Phytoplankton Productivity in Lake Naivasha and the Status of Control

The paper presents data collected in an assessment of the effects of water hyacinth （Eichhornia crassipes） infestation on phytoplankton productivity in Lake Naivasha. A summary of the status of control and strategies used is given. The ecological effects of water hyacinth on the lake have received little attention compared to the large body of work available on the weed＇s socioeconomic impact. This study was conducted to determine the effect of hyacinth infestation on the phytoplankton productivity. Several sampling stations were set up in the lake at sites containing floating mats of the weed and at sites where the weed was absent. Phytoplankton chlorophyll-a concentration and dissolved oxygen were measured at each station and used as proxies for phytoplankton productivity. The findings show that phytoplankton productivity in weed covered areas is reduced with significant change in species composition and biodiversity suggesting that water hyacinth can alter the ecology of the lake. Although water hyacinth has continued posing serious ecological consequences, the control strategies already adopted will continue to reduce deleterious impacts and allow sustained development in the Lake Naivasha Basin. There is need however to undertake research to quantify the level of ecological damage and the costs of control. There are other effects such as livelihood loss, diseases, and disruption of normal operations that also need to be quantified.
