2. Characteristics and Manufacture of Spherical Smokeless Powders
ABSTRACT: Smokeless propellants have been studied and manufactured for many decades. They can exist in various physical forms and also can have different properties according to the use of each propellant. One important form of smokeless powders is the ball powder, which has spherical grains. The manufacture process of the ball powder has many advantages ove

3. ADN - The new oxidizer around the corner for an environmentally friendly smokeless propellant
Abstract: The search for a smokeless propellant has encouraged scientists and engineers to look for a chlorine-free oxidizer as a substitute for AP (ammonium perchlorate). Endeavors seemed to come to an end when ADN (ammonium dinitramide) appeared in the West in the early 1990s. Although some drawbacks soon became apparent by that time, the foremost obstacle

4. Estudo da decomposição térmica de propelente sólido compósito de baixa emissão de fumaça
The thermal decomposition of hydroxyl-terminated polybutadiene (HTPB)/ammonium nitrate (AN) based propellants, so called smokeless formulations, and raw materials were investigated by differential scanning calorimetry (DSC) and thermogravimetry (TG). The thermoanalytical profile of different components and of propellant were evaluated and the Arrhenius param

5. DeterminaÃÃo dos parÃmetros cinÃticos de um propelente de foguete sem fumaÃa (smokeless) via anÃlise tÃrmica.
Os propelentes com baixa emissÃo de fumaÃa sÃo usados em motores foguetes por terem uma melhor camuflagem e de um melhor controle de direcionamento no campo de batalha, devido ao fato de apresentar maior dispersÃo de fumaÃa lanÃada no ar em comparaÃÃo com os propelentes tradicionais. No desenvolvimento destes propelentes de alto desempenho sÃo utili

6. The user s of smokeless tobacco profile / Perfíl do usuário de tabaco sem fumaça
Analisando o tabagismo, nota-se o declínio no uso do cigarro pelas campanhas populacionais sobre os malefícios causados pelo vício de fumar. Houve, porém o ressurgimento de um vício milenar presente em rituais e costumes das sociedades indígenas americanas e também praticado por egípcios, persas e chineses desde o ano 1000 a.C.: o uso do tabaco sem f

11. Subtilisin Increases Macromolecular Efflux from the Oral Mucosa
The purpose of this study was to determine whether subtilisin, a potent serine proteinase derived from Bacillus species contaminating smokeless tobacco, increases macromolecular efflux from the oral mucosa and, if so, whether local elaboration of bradykinin mediates this response. Using intravital microscopy, I found that suffusion of subtilisin elicits sign

12. Effect of nicotine on secretory component synthesis by secretory epithelial cells.
Previously, we reported that secretory component (SC), lactoferrin (LF), and lysozyme (LY) levels were significantly lower in saliva from smokeless tobacco (ST) users than in saliva from control non-tobacco users. However, the levels of salivary immunoglobulin A were significantly higher, albeit with an altered attachment of SC, in ST users than in control s
