Wireless communication has become a preferred direction for the development of layered water injection tools due to its low cost and high reliability. However, wireless system relies on underground battery power supply，and each will consume significant amount energy. In order save energy consumption, adopts intermittent sleep mode, with intervals usually more than one month. During idle time co...

Web applications are exposed to myriad security vulnerabilities related to malicious user string input. In order to detect such vulnerabilities in Java web applications, this project employs string constraint analysis, which approximates the values that a string variable in a program can take on. In string constraint analysis, program analysis generates string constraints – assertions about the...

The problem of leakage production strings in and injection wells is becoming more urgent every year Russia’s fields. As a result, the water encroachment produced products increases, as operation becomes unprofitable. main reasons for are aging well stock, poor quality cementation during final works drilling, corrosion processes places where aquifers come into contact with string, killing at pre...

The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...

OBJECTIVE To compare the plaque removal efficacy of a water flosser to string floss combined with a manual toothbrush after a single use. METHODS Seventy adult subjects participated in this randomized, single-use, single-blind, parallel clinical study. Subjects were assigned to one of two groups; Waterpik Water Flosser plus a manual toothbrush (WF) or waxed string floss plus a manual toothbru...

In this work, we propose the use of an air segment in a sequential injection system to simultaneously improve the overlapping of the stacked zones and minimise dispersion. This strategy was developed for the determination of sulphate in natural and wastewaters. Barium chloride was used as a precipitating agent and the turbidity of the suspension formed was measured at 420 nm. Analysis was perfo...
