Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics
The explicit solution to Cauchy problem for linearized system of two-dimensional isentropic flow with axisymmetrical initial data in gas dynamics is given.
Photocatalytic Oxidation of Aniline in the Gas Phase Using Porous TiO2 Thin Films
The gas-phase photocatalytic oxidation of aniline on a new kind of porous nano-TiO2 composite films is investigated.
Acetone solution-casting films of poly(methylmethacrylate) were analyzed by differential scanning calorimetry and pyrolysis gas chromatography-mass spectroscopy under natural evaporation and ultrasonic vibration, respectively.
The former workers at the Okunojima poison gas factory (poison gas workers) are a high-risk group for malignant neoplasms and show abnormalities in cellular immunity.
At the same time, poison gas workers often have chronic respiratory diseases, such as chronic bronchitis, and are highly susceptible to respiratory infections.
To explore the possibility of immunological cancer prevention, we have periodically administered 200 μgNocardia rubra cell-wall skeleton (N-CWS) to poison gas workers once every 3 months since December 1978.
During this period, we noted a significantly lower incidence of influenza among poison gas workers receiving N-CWS than in those not receiving the drug during the influenza epidemic.
Therefore, periodical administration of N-CWS to poison gas workers was considered to enhance the reduced T-cell function of normalizing antibody production by stimulating the production of B-cell-stimulatory factor (BSF).
With the fast development of the urban construction,high density population,expensive land,more and more high-rise buildings and even skyscrapers stand out in cities.They are mostly up-to-dated,macro-scale operated and multi-functioned.Due to its high-rise floor,complicated function and various facilities, 3-dimensional burning,thick smog and toxic gas pose great threat to people's lives in case of fire.Therefore,evacuation and rescued word may be held up.It may cause a fatally economic loss and heavy casualties...
With the fast development of the urban construction,high density population,expensive land,more and more high-rise buildings and even skyscrapers stand out in cities.They are mostly up-to-dated,macro-scale operated and multi-functioned.Due to its high-rise floor,complicated function and various facilities, 3-dimensional burning,thick smog and toxic gas pose great threat to people's lives in case of fire.Therefore,evacuation and rescued word may be held up.It may cause a fatally economic loss and heavy casualties as well.Although there are many breaking-loose methods available for people in these buildings,they still face desperate situations and danger.This paper is to offer a more realistic and secure escaping method-Domino-Rope,which is a more effective approach to people trapped in a fire.
The underground public space is the important place where the people get together.The consequences from disaster in underground public space are more severe than that in aboveground ones.Compared with the evacuation stairs,the disaster prevention square can not only reduce the trouble,but also attract more people.In this paper,the necessary for setting up the disaster prevention square in underground space and how to design it is preliminary discussed.
In view of the emergencies such as chemical and biological terrorist attacks,proposes that the dose and dose-response relationship of chemical and biological weapon(CBW) agents should be taken as the basis of design and operation of the HVAC system.Presents the basic concept of dose,main routes of CBW agents invading people,and common parameters of dose.Presents the basic concept of dose-response relationship and relevant models of epidemiology and toxicology.Gives one general model and plots the dose-response...
In view of the emergencies such as chemical and biological terrorist attacks,proposes that the dose and dose-response relationship of chemical and biological weapon(CBW) agents should be taken as the basis of design and operation of the HVAC system.Presents the basic concept of dose,main routes of CBW agents invading people,and common parameters of dose.Presents the basic concept of dose-response relationship and relevant models of epidemiology and toxicology.Gives one general model and plots the dose-response curves of Bacillus anthracis and sarin based on it.Taking the attack scenarios for example,in which bacillus anthracis and sarin are continuously released into a room,calculates the variation of the concentration of agents in the air and the accumulate fatalities under six operate conditions.Obtains preliminary rules and suggestions through analysis and discussion.
