size reduction of high energy materials such as 1, 3, 5, 7-tetranitro- 1, 3, 5, 7-tetraaza cyclooctane (hmx) has considerable influences on improving their explosive characteristics. in this study, nanosized hmx par­ticles were produced using ultrasonically reprecipitation method by applying water as a safe and accessible antisolvent instead of unsafe conventional methods. sem photographs revea...

Majority of organizations have a high dependence on the role information technology (IT). IT has very important for business, so implementation needs to be protected from various threats and disruptions avoiding failures occurrence risks that will poor impact business activities organization. To ensure sustainability an organization continuity planning (BCP) document. BCP is complete set proced...

Observations of strong solar wind proton flux correlations with ROSAT X-ray rates along with high spectral resolution Chandra observations of X-rays from the dark Moon show that soft X-ray emission mirrors the behavior of the solar wind. In this paper, based on an analysis of an X-ray event observed by XMM-Newton resulting from charge exchange of high charge state solar wind ions and contempora...

Free-standing transmission gratings will be used in a new generation of space instruments for magnetosphere energetic neutral atom (ENA) imaging which requires efficient suppression of the exceptionally strong background extreme ultraviolet (EUV) and UV radiation. The first results of the experimental study of grating (period 200 nm) optical properties in the 50130 urn wavelength range are pres...
