Asthma morbidity and mortality has increased. One of the possible causes is the excessive use of beta agonists. The aim of this study is to compare the effects of six week treatment with beclomethasone alone (Ibec) or the combination of beclomethasone-salmeterol (Ibe + Isal) on serum potassium (K), CPK-MB and ECG in children suffering asthma. It was a prospective, randomised, open cross-over tr...

The three-dimensional finite element model of the postoperative whole human eye after small incision lenticule extraction (SMILE) surgery and axisymmetric air-puff were established, influencing factors in Air-puff test explored from displacement nephogram on anterior corneal surface. Our results showed that maximum depression was positively correlated with corrected diopter when peak pressure e...

In this paper, an algorithm for detecting and attenuating puff noises frequently generated under the mobile environment is proposed. As a baseline system, puff detection system is designed based on Gaussian Mixture Model (GMM), and 39th Mel Frequency Cepstral Coefficient (MFCC) is extracted as feature parameters. To improve the detection performance, effective acoustic features for puff detecti...

Thermal recovery is still the most important means to increase heavy oil EOR. With in factor and difficulty of exploiting new exploration reserves, efficient utilization offshore reserves has attracted much attention. However, due challenges high development investments, operating costs, platform safety factors, economic cumulative yield, nearly 700 million tons have not been effectively utiliz...

Horizontal well fracturing technology is widely used in unconventional reservoirs such as tight or shale oil and gas reservoirs. Meanwhile, the potential of enhanced recovery (EOR) methods including huff-n-puff miscible injection are to further increase The complexities hydraulic fracture properties multiphase flow make it difficult time-consuming understand performance (i.e., production) fract...

Huff curves are well known for efficient arithmetics to their group law. In this paper, we propose two deterministic encodings from Fq to generalized Huff curves. When q ≡ 3 (mod 4), the first deterministic encoding based on Skalpa’s equality saves three field squarings and five multiplications compared with birational equivalence composed with Ulas’ encoding. It costs three multiplications les...

We show that for the Hardy class of functions H 1 with domain the ball or polydisc in CN , a certain type of uniform convexity property (the uniform Kadec-Klee-Huff property) holds with respect to the topology of pointwise convergence on the interior; which coincides with both the topology of uniform convergence on compacta and the weak ∗ topology on bounded subsets of H 1. Also, we show that i...

During oilfield development, there exist multi-cycle gas–water mutual displacement processes. This means that a cycling process such as water driving gas–gas driving water–water driving gas is used for the operation of injection and production in a single well (such as foam huff and puff in single well or water-bearing gas storage). In this paper, by using coreand micro-pore scales model, we st...
