PBXN-109EB is a new plastic bonded explosive containing energetic binder system NHTPB-NPB that has better performance and energetic properties than PBXN-109. In this work, at first, kinetic parameters of thermal decomposition were extracted via kissinger method and differential scanning calorimetery (DCS) technique for PBXN-109EB in various heating rates and then its decomposition half-life (ag...
Use of energetic plasticizer, N-Butyl-N-(2-Nitroxyethyl) Nitramine (BuNENA), in the propellants’ formulations, has some advantages such as not migration in the fuel, high thermal stability, low sensitivity of the propellant formulation, improvement in mechanical properties and raising the impulse due to light molecular weight of combustion gases. In this study two acidic ionic liquids ([(...
1) RFC 892 is an older version of the ISO Transport Protocol Specification. Therefore this RFC should be assumed to supercede RFC 892. 2) This document has been prepared by retyping the text of ISO/TC97/SC16/N1576 and then applying proposed editorial corrections contained in ISO/TC97/SC16/N1695. These two documents, taken together, are undergoing voting within ISO as a Draft International Stand...
The Earth’s ring current and how it responds to varying interplanetary conditions is described and an account provided of the production of Energetic Neutral Atoms (ENAs) in the geo-corona. Also, the potential to remotely monitor, on a global scale, the temporal and spatial evolution of magnetospheric plasma populations through analysing ENA images recorded during magnetic storms/substorms is i...
[1] The first all‐sky maps of Energetic Neutral Atoms (ENAs) from the Interstellar Boundary Explorer (IBEX) exhibited smoothly varying, globally distributed flux and a narrow “ribbon” of enhanced ENA emissions. In this study we compare the second set of sky maps to the first in order to assess the possibility of temporal changes over the 6 months between views of each portion of the sky. While ...
In this study, computational synthesis of carbon nanostructures' derivatives with TATB or 2,4,6-triamino-1,3,5- trinitrobenzene , which is an energetic substance in the temperature range of 300-400 K were evaluated by density functional theory method. In this regard, at the outset, the substances in the both sides of intended reactions for forming the desired products were optimized geometrical...
مقدمه و هدف: اهداف کلی باید در یک بیانیه خط مشی کیفیت مدون شود و بیانیه به امضای بالاترین مقام اجرایی برسند. این بیانیه حداقل باید شامل مراحل مختلف باشد. آزمایشگاه باید خط مشی ها، سیستم ها، برنامه ها، روش های اجرایی و دستورالعمل های خود را تا حدی که برای تأمین کیفیت نتایج آزمون ضروری باشد، مستند سازد مواد و روش کار: در حال حاضر استاندارد بین المللیiso/iec 17025 که در نتیجه تجربیات وسیع حاصل از ...
With a dataset of more than 600 million small RNAs deeply sequenced from mouse hippocampal and staged sets of mouse cells that underwent reprogramming to induced pluripotent stem cells, we annotated the stem-loop precursors of the known miRNAs to identify isomoRs (miRNA-offset RNAs), loops, non-preferred strands, and guide strands. Products from both strands were readily detectable for most miR...
gallium extraction from jajarm bayer process liquor (jajarm, iran) was investigated using microemulsions. also the behavior of aluminum was studied as an impurity. kelex100 (4-ethyl, 1-methyl, 7-octyl, 8-hydroxyquinoleine), iso-decanol and n-butanol, and kerosene were used as the surfactant, co-surfactant, and oil phase, respectively. ternary phase diagrams were produced using various co-surfac...
