Method discussion for quick response grey prediction of stronger aftershocks of an earthquake sequence

In this paper, we take occurrence process of early strong aftershocks of a main after shock type′s earthquake sequence as a complex grey system, and introduce predicting method for its stronger aftershocks by grey predicting theory. Through inspection prediction for 1998 Zhangbei M S=6.2 earthquake sequence, it shows that the grey predicting method maybe has active significance for the investigation of quick response prediction problems of stronger aftershocks of an earthquake sequence.

Urtra-Hard Bonds in P-Carbon Stronger than Diamond

The hardness and ideal strength of P-carbon, i.e., a new carbon phase for the cold-compressed carbon with an orthogonal structure recently proposed and named as P-carbon, are investigated by means of first-principles calculations. The strength calculations reveal that the failure mode in P-carbon is dominated by the tensile type. The ideal tensile strength of P-carbon is calculated to be 76.T GPa in the [001] direction, which is higher than that of the previously known most stable Z-carbon, of 71.4 GPa. Meanwhile, the theoretical Vickers hardness of P-carbon is estimated as 89 GPa, which is comparable with that of diamond. Especially, two types of bonds in P-carbon with hardness values of 114 GPa and 105 GPa are significantly stronger than those of diamond. The results provide insight into exploration of the ultra-hard P-carbon for potentially technological applications.

Imagining exercise can make you stronger

A new research study suggests that just thinking of exercising can have the same effects as actually hitting the gym, officials say. A recent study published in the Journal of Neurophysiology found that simply imagining exercise can tone muscle, delay atrophy, and even make your muscles stronger.

Stronger Yuan Arouses Concern

THE exports of Beijing Haifu Trading Co. Ltd. last year were 4 percent higher than those in 2012. but the company didn＇t make much money, accord- ing to Li Haifu. owner of the company. Sitting in the Dahongmen area. Haifu is mainly engaged in the production of curtains and beddings. with most of its products being exported. According to Li. for exported products, the U.S. dollar is used at all stages from ordering to settling, and it takes four months for the company to collect the payment for goods. Owing to fierce competition in the textile market, the prices charged cannot be too high.

Protective effect and mechanism of stronger neo-minophagen C against fulminant hepatic failure

AIM: To investigate the protective effect of stronger neo-minophafen C (SNMC) on fulminant hepatic failure (FHF) and its underlying mechanism. METHODS: A mouse model of FHF was established by intraperitoneal injection of galactosamine (D-Gal N) and lipopolysaccharide (LPS). The survival rate, liver function, inflammatory factor and liver pathological change were obtained with and without SNMC treatment. Hepatocyte survival was estimated by observing the stained mitochondria structure with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate fluorescence nick end labeling (TUNEL) method and antibodies against cytochrome C (Cyt-C) and caspase-3. RESULTS: The levels of plasma tumor necrosis factor alpha (TNF-α), nitric oxide (NO), ET-1, interleukin-6 (IL-6), and the degree of hepatic tissue injury were decreased in the SNMC-treated groups compared with those in the model group (P < 0.01). However, there were no differences after different dosages administered at different time points. There was a significant difference in survival rates between the SNMC-treated groups and the model group (P < 0.01). The apoptosis index was 32.3% at 6 h after a low dose of SNMC, which was considerably decreased from 32.3% ± 4.7% vs 5% ± 2.83% (P < 0.05) to 5% on d 7. The expression of Cyt-C and caspase-3 decreased with the prolongation of therapeutic time. Typical hepatocyte apoptosis was obviously ameliorated under electron microscope with the prolongation of therapeutic time. CONCLUSION: SNMC can effectively protect liver against FHF induced by LPS/D-Gal N. SNMC can prevent hepatocyte apoptosis by inhibiting inflammatory reactionand stabilizing mitochondria membrane to suppress the release of Cyt-C and sequent activation of caspase-3.

“Being Stronger,Better and Bigger”:The Logical Unity of Theory and Practice of State-owned Enterprise Reform-Development Course and Prospect of State-owned Enterprises in China

China’s state-owned enterprises(SOEs)have developed more than 70 years since the People’s Republic of China(PRC)was founded in 1949.From 1949 to 1978,SOEs provided material guarantee for the construction of the PRC,laid a solid foundation for the industrialization process,and ensured that the people were masters of their own affairs.From 1978 to 2012,SOEs upgraded their growth quality and increased their efficiency for improving people’s material and cultural life.Since 2012,SOEs have become“stronger,better and bigger”on all fronts for satisfying people’s growing expectations for a better life.In essence,reforming SOEs means interpreting and exercising the people-centered development philosophy,and means addressing principal social contradiction through different stages of socialist development,as SOEs care about the main needs of the people.Such a development is a process of constant exploration and continuous growth from strength to strength,which is the inherent logic of theory and practice of SOE growth in new China for more than 70 years.

Effect of a less permeable stronger soil layer on the stability of non-homogeneous unsaturated slopes

Slope failure occurs due to an increase in the saturation level and a subsequent decrease in matric suction in unsaturated soil.This paper presents the results of a series of centrifuge experiments and numerical analyses on a 55°inclined unsaturated sandy slope with less permeable,stronger silty sand layer inclusion within it.It is observed that a less permeable,stronger silty sand layer in an otherwise homogeneous sandy soil slope hinders the infiltration of water.The water content of the slope just above the stronger layer increases significantly,compared to elsewhere.No shear band is found to initiate in a homogeneous sandy soil slope,whereas for a non-homogeneous slope,they initiate just above the less pervious,stronger layer.A discontinuity of the shear zone is also observed for the case of a non-homogeneous soil slope.The factor of safety of a non-homogeneous,unsaturated soil slope decreases because of the less permeable,stronger layer.It decreases significantly if this less permeable,stronger soil layer is located near the toe of the slope.
