In this paper, the effects of hyperthermia on cells and immune system are introduced briefly. The mechanism of action of hyperthermia on human papilloma virus (HPV)-infected skin diseases was elaborated as an example in this paper. Many studies have proved that hyperthermia affects a number of cellular and molecu- lar constitutes in the skin immune system, involving both innate and adaptive immune responses; the efficacy of hyperthermia in treating some infectious and cancerous conditions has been validated and applied in clinics, while molecular mechanisms of hyperthermia affecting the immunereaction is still unclear.  相似文献

In this paper the research status of lateral shift of reflected electromagnetic wave at the interface of conductive media was reviewed, the lateral shift and the lateral delay were analyzed, and the charac- teristic of lateral shift curves varying with the angle of incidence was introduced in detail. For electro- magnetic wave logging, the error correction method of lateral shift was stressed in this paper, the magnitude of measured errors caused by the lateral shift was established. It is noticed that the longer wavelength, the larger error of measured results. With respect to the effect of lateral shift, the problem which still needs to be settled in the measurement of electromagnetic wave, as well as prospects on the further research and applications of lateral shift are described.  相似文献

1 Results Sulfonylsemicarbazide derivatives are important compounds as blowing agents in cellular rubber and plastics[1]. Different methods for the preparation of these compounds are reported. For example, sulfonylsemicarbazides are prepared by reaction of sulfinic acid salt with azodicarbonamide in water[2] and reaction of sulfonylchloride with semicarbazide[3-4]. In these methods the yields of products are not high[3-4], the solvent such as pyridine is toxic and also the sulfinic acid salt as starting material is not commercially available[2]. Recently, triphosgene [bis(trichloromethyl)carbonate], a crystalline solid which can be easily handled, was reported as a safe stable reagent[5]. It was successfully utilized to the synthesis of large variety of organic compounds[6].  相似文献

In this paper we are concerned with the existence of positive entire solutions of second order quasilinear elliptic equations of the type div(|Du|p-2Du)+f(x,u)=0, x∈RN, (1) where f(x, u) is a continuous function on RN×(0,∞). This problem appears in the study of non-Newtonian fluids and non-Newtonian filtration. The quantity p is a characteristic of the madium. Media with p>2 are called dilatant fluids and those with p<2 are called pseudoplastics. If p=2, they are Newtonian fluid. In the present paper we give new sufficient conditions which ensure the existence of positive entire solutions of (1).When p=2, the related results have been obtained by [1,2]. Our theorem for existence complement and extent to the results by [1,2].  相似文献

Since the early work of O. M. Bilanuik and B. C. Sudarshan in 1962 and G. Feinberg in 1967, the research work on the faster-than-light (superluminal) has been performed in the world, such as in USA, Europe and China. In this paper, the development stages of the study are presented, which include beginning stage, transitional stage and experimental stage. Based on the Einstein‘s paper in 1905, the velocities greater than that of light had no possibility of existence. However, in the Einstein‘s papers of 1907 it was founded that the superluminal signal speed could not be refuted absolutely. In this paper, the studies on velocities are classified. The definition of General Information Speed is suggested, which will ease the discussion. After reviewing the researches of 1962-2004, it can be concluded that the faster-than-light is a realizable scientific statement.  相似文献

This paper analyses the principles of the recommended method for measuring errors of PAL chrominance signal demodulation angle, which is constituted in IEC Publication 107-1[1]. Analysis shows that by means of above method, the measured phase matching error and amplitude matching error of delayed and undelayed signals are mixed with other errors. Thus the measurement results, especially for phase matching error, cannot correctly reflect the errors in associated circuits and cannot be used for assessing the properties of the comb filter or the receiver. In this paper, authors propose that the measuring signal and the measured point in the receiver should be changed. Practical measurement and observation of the line crawl on screen show that the modified method is more effective and more reasonable.  相似文献

In this paper, by applying the uniform persistence of infinite dimensional dynamical systems in paper[1][2], the model in paper [3] is analysised, and the sufficient conditions of the uniform persistence are obtained. And the method of proof in this paper simplifies that of the paper [3] and moreover, the method is more easier to be improved.  相似文献

The concept of fuzzy measure was introduced by Sugeno in 1974. A notion of signed fuzzy measure is introduced in this paper, and its elementary properties are briefly discussed. An analogue of Hahn decomposition theorem is established under the null-null-additive condition. A version of the Jordan decomposition theorem is proved under the null-additive condition.  相似文献

Ralph Waldo Emerson, born in 19th century's America, is most famous for his transcendental ideas and writings. He was deeply influenced by European Romanticism in his thirties and formed an informal Transcendental Club with people of like minds. His thought is often considered the core of Transcendentalism. "Nature" is the fundamental document of his philosophy and an embodiment of his transcendental attitude towards the phenomenal world. He also wrote some other brilliant essays such as "The American Scholar", "Self-Reliance", "The Over-Soul" and "The Poet", etc, all of which established his indisputable position in the history of culture, especially in the American Culture where he is regarded as the one who, in literally terms at least, really put America on map. But considering Emerson's writings without significant emphasis on his verse would be a great loss. Emerson wrote poetry from the time he was a boy to nearly the end of his life. These poems are essential for understanding him and his transcendental theories and are receiving more extensive representation in anthologies while significant critical analyses are emerging though some modern readers and scholars tend to view his poetry as secondary to the "essential" Emerson. In view of the above, this paper supposes to introduce Emerson's views on poets and poems and then analyze some of his famous poems in the order of 'Emerson as a Poet', 'Emerson's Views on Poets and Poems' and 'Emerson's Poems' with the third one as the focus of this paper. The purpose of this paper is to try to make the comprehension on Emerson and his abstract transcendental theories more complete and thorough by emphasizing his contribution in the poetic field.  相似文献

INTRODUCTIONLong-time preservation leads books and archives to discoloration or the reduction of folding endurance of paper, which curtail their life span. Discoloration occurs more frequently in paper which was particularly produced from mechanical pulp [1]. Aging rate even in acidic paper increases so that its possible preservation span is, at most, 50 years or so [2]. Previous studies show that the major cause of paper deterioration is the acid-catalyzed hydrolysis of cellulose by…  相似文献

The accidents at the Fukushima Daiichi nuclear power station stunned the world as the sequences played out over several days and video of hydrogen explosions were televised as they took place. The accidents all resulted in severe damage to the reactor cores and releases of radioactivity to the environment despite heroic measures taken by the operating personnel. The following paper provides some background into the development of these accidents and their root causes, chief among them, the prolonged Station Blackout Conditions that isolated the reactors from their ultimate heat sink – the ocean. The interpretations given in this paper are summarized from a recently completed report funded by the USDOE [1].  相似文献

1 Results Humidity sensors have been widely used in meteorology, process controlling, agriculture and manufacturing. In recent year, more attention has been paid to resistive-type polymeric humidity sensors. Polyelectrolytes are the most usually used materials for their advantages of high sensitivity, fast response, easy preparation, low cost, etc[1,2]. In this paper quaternized and salt-doped copolymer of 2-(dimethylamino) ethylmethacrylate (DMAEMA) with poly(ethylene glycol) methyl ether methacrylate (PEGMEMA) were prepared and used for the construction of resistive thin film humidity sensors. Salt-doped PEGMEMA was used to improve the conductivity of sensors in dry atmosphere, while 2-(dimethylamino) ethyl methacrylate (DMAEMA) which was quaternized with n-butyl bromide (BB) was employed to maintain good humidity sensitive properties.  相似文献

Luminescence study from the silicon oxide films embedded nm carbon particles (CSO) and nm silicon particles (SSO) is of great importance in integrated optoelectronics[1]. The pioneering work on electroluminescence (EL) from the SSO was reported by Dimaria et al[2]. They attributed the light emission to band-band recombination of electron-hole pairs in nanosize silicon particles. This model is referred to as the quantum confinement model. In this paper,we deposit CSO and SSO films onto p-type Si substrate and study comparatively visible EL from the Au/CSO/p-Si and Au/SSO/p-Si structures.  相似文献
