Mountaineer Destroys Myth Of The "Yeti"

1998年10月上旬,德国的法兰克福正在举办第30届 Book Fair。Frankfurt Book Fair 是当今世界最大的书市。书市爆出一条新闻:ReinholdMessner 以其多次访问喜马拉雅山地区的冒险经历写了一本题为“Yeti”的书,并举行了记者招待会。其实,对于“Yeti”,并非新鲜名词。前人对这个“喜马拉雅山之谜”早有探究。《英汉大词典》就对 Yeti 一词提供了释义:Yeti=AbominableSnowman,雪人,传说生存于喜马拉雅山上的一种动物,据信是熊。而 ReinholdMessner 在喜马拉雅山地区的探险见闻,不过是证实了“据信是熊”这一点而已(claims to confirm this with the help of photos taken during severalencounters)。可是,德国的几家报刊却对他的发现提出质疑。其实,作者作为一个探险家的精神是不能抹杀的。作者对 Yeti 的描述一定扣人心弦。本文提及的世界另一著名“怪兽”:Scotland's fabled Loch Ness monster。据报道,那也不过是一种庞大怪异的水生动物而已。

Destruction mechanism of gas explosion to ventilation facilities and automatic recovery technology

In order to overcome the heavy casualties caused by gas explosion, we verified the propagation law of shock wave in pipeline and the overpressure distribution of gas explosion by similar experiments according to the analyses of reasons for casualty and ventilation system model destroyed by gas explosion in the mining face. We summarized the gas composition after the explosion and its danger, analyzed the effects of the gas explosion shock wave to ventilation system and facilities and the laws of toxic gas spread and diffusion in the ventilation network after the explosion. We presented a technical proposal to control the smoke and recover the ventilation system after a gas explosion and developed a reserve air door and control system that were embed in the lane, and could close automatically in conditions of no pressure and electricity. The results showed that the reserve air door normally opened and could close automatically controlling the smoke flow and resuming the ventilation system when the gas explosion shock wave destroyed the original shutting air door which resulted in the air short circuit.

Noninvasive treatment efficacy monitoring and dose control for high-intensity focused ultrasound therapy using relative electrical impedance variation

As an effective therapeutic modality, high-intensity focused ultrasound（HIFU） can destroy tumour tissues by thermocoagulation with less metastasis, but it is still limited by inaccurate non-invasive temperature monitoring and efficacy evaluation. A model of electrical impedance measurement during HIFU therapy was established using the temperatureimpedance relationship. Based on the simulations of acoustic pressure, temperature, and electrical conductivity, the impedance of the phantom was calculated and experimentally demonstrated for different values of acoustic power values and treatment time. We proved that the relative impedance variation（RIV） increases linearly with the increasing treatment time at a fixed acoustic power, and the relative impedance variation rate shows a linear relationship with the acoustic power.The RIV and treatment time required for HIFU treatment efficacy are inversely proportional to the acoustic power and the square of acoustic power, respectively. The favourable results suggest that RIV can be used as an efficient indicator for noninvasive temperature monitoring and efficacy evaluation and may provide new strategy for accurate dose control of HIFU therapy.

Destroying a Peldan Electrostatic Solution Black Hole

By throwing a particle with electric charge and angular momentum into the black holes, much evidence shows that the naked singularity of some （3＋1）-dimensional black holes might be seen, which is not allowed in the weak cosmic censorship conjecture. In this study, we consider a （2＋1）-dimensional Peldan black hole and find that it could be destroyed under certain conditions in both extreme and near-extreme cases.

Corrosion Mechanism of E-glass of Chemical Resistance Glass Fiber in Acid Environment

The corrosion of ECR glass fiber was investigated by the analysis methods of weight loss ratio under different acids and at various durations.Weight loss,leaching of cations,and surface composition of ECR glass fiber were analyzed.The corrosion mechanism of ECR glass fiber in acid environment was also discussed.The experimental results showed that the corrosion degree of ECR glass fiber in different acids obeyed the order： HNO3〉H2SO4〉HCl.The acid effects on corrosion of ECR glass fiberis were totally different.Hydrochloric acid mainly destroyed the network structure of [AlO4],while sulfuric acid and nitric acid mainly destroyed the structure of [SiO4].The acid resistance of ECR glass fiber is much better than that of E glass fiber due to the generation of intermediate product silicic acid gel Si（OH）4 during ion exchange.It can adhere to the glass surface to form a thin film and hinder the proceeding of corrosion.

从我国封建社会看传统文化与设计的关系

所谓设计是指对现有事物的突破并加以创新的过程。从英文的DESIGN来看，其由de及sign两部分合成，de代表destroy，即破坏的意思，sign则是记号的意思，因此其意思可以说是对既有的事物突破、重新组合或发明而创造新的事物。一块天然的岩石不具备文化意蕴，但经过人工打磨，便注入了人的价值观念，进入“文化”范畴。所谓文化．是人类复杂历史经验的全部成果，文化作为一民族成员共同遵守的一种思想和行为模式，它将某一民族和其他民族区分开来。可以说，一种文化即一种生活方式的总和。文化既包括血缘、地缘、语言、宗教、仪式、艺术、器物、组织、社会、经济、政治、哲学等进而探究，这个民族所呈现出来的是否有共通的基础或规则。

Clinical Trial of Medicinal Synthetic Aluminum-Magnesium Silicate (Antivirt®) on Viral Loads and CD4-Lymphocytes Counts of HIV/AIDS Patients

For clinical trial of Medicinal synthetic Aluminum-magnesium silicate (MSAMS, Antivirt®), on viral loads and CD4-lymphocytes counts of HIV/AIDS patients, 10 volunteers were treated. Their blood samples were tested for viral loads and for CD4-lymphocytes counts, before the treatment and every 4 weeks during the medication. The regimen was: MSAMS (50 mg/kg), MSAMS-stabilized Ampicillin trihydrate (7.5 mg/kg) and immunace extra protection® (1 tablet/day), for 4 weeks. Then, it was reduced to 50 mg/kg (MSAMS) and the immune stimulant. When their viral loads become undetectable, they would be treated for additional 4 weeks. Initially, the Antivirt®-regimen appeared to worsen both HIV infection-load and immune deficiency but later relieved them. Patients’ mean-viral load increased (P = 0.020), from 1820.30 ± 868.75 to 2855.90 ± 960.98, after 4 weeks before reducing (P = 0.030) to 1565.20 ± 743.17, after 8 weeks. Similarly, their mean-CD4-lymphocytes count reduced (P = 0.008) from 496.80 ± 194.39 to 263.90 ± 149.26, after 4 weeks before improving (P = 0.001) to 507.90 ± 133.19, after 8 weeks.

Hammerhead ribozymes as unique tools for gene therapy of HPV-related cancers

Hammerhead ribozymes are small RNA moleculesthat bind to a complementary sequence of RNA andcleave that sequence at a conserved triplet NUX (N =G, A, X = A, U, C). ln comparison with ilntisensemolecuIes, ribozymes not only bind to target RNA butalso cleave the target at predicted sites. They havebeen used as molecular agents to destroy either viralRNA or oncogene transcripts in human cancers. Manyhuman cervical and oral carcinomas express RNA

A Method to Defend File-Attacking

The paper points out that the deep reason why modern computer system fails to defense malware lies in that user has no right to control the access of information, and proposes an explicit authorization mechanism. Its basic idea is that user explicitly authorizes program the file set it can access, and monitor all file access operations; once program requests to access file out of the authorized file set, refuse it, and this means that the program is malicious or has design errors. Computers based on this novel mechanism can protect information from attacking reliably, and have good software and hardware compatibility. A testing system is presented to validate our theory.

Analysis of Functional Group of Alkaline Phosphatase from DFRKN-1

To further understand characters of alkaline phosphatase and provide reference for in-depth study of the mechanism of NFRKN-1 invading into knot nem-atode and its development and utilization, the effects of metal ions, organic reagents and chemical modifier on activity of alkaline phosphatase from DFRKN-1 were analyzed in the paper. The results showed that Mg^2＋ , Ba^2＋ and K^＋ under certain concentrations activated enzyme significantly and Zn^2＋ could inhibit enzyme activ-ity. Methanol, ethanol and ethylene glycol inhibited enzyme activity in similar degrees. Histidine residue and Lysine residue are essential groups of alkaline pbos-phatase; sulflaydryl of cysteine was not an essential group, but disulfide bond played an important role in maintaining the active conformation of alkaline phospha-tase.
