Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate. AP particles at the micro and nano-scales, have a great influe...
در این پایان نامه، حلقه های –aps انژکتیو را به عنوان تعمیمی از حلقه های –ps انژکتیو و حلقه های –ap انژکتیو معرفی می کنیم و مثال های زیادی از حلقه های –aps انژکتیو بیان می کنیم. همچنین برخی نتایج بدست آمده برای حلقه های –ap انژکتیو و –ps انژکتیو را به حلقه های –apsانژکتیو توسیع می دهیم.
of the Caucasian population. The purpose of this study was to investigate the morphometry of the proximal tibia in thestandard resected surface of total knee arthroplasty (TKA).Methods: In this descriptive study, the anthropometric data of the proximal tibia were measured in 132 knees (80 malesand 52 females) using magnetic resonance imaging in 2015. The collected data include...
In this paper the Cross-linked double base propellant (XLDB) based on polyurethanes comprised of polycaprolactone (PCP) as binder and ammonium perchlorate (AP) and RDX as solid oxidizer have been prepared and characterized. Propellant burning rate were determined by the strand burner method (Crawford bomb). In the AP-based composition, the energy is enhanced and the pressure exponent reduced ...
Objective(s): K+ channel blocker 4-aminopyridine (4-AP) stimulates the release of glutamate from nerve terminals and induces seizures. Berberine as a potential herbal drug exerts several pharmacological actions on the central nervous system including anxiolytic, anticonvulsant, and neuroprotective properties. The present study aimed to investigate the effect of berberine on seizure onset and ti...
Background. Many mechanisms are involved in pain transmission in the spinal cord. Therefore, combination of drugs acting on different kinds of mechanisms might be useful for analgesia. We investigated the interaction betweenγ-aminobutyric acid （GABA）B receptor agonist, baclofen, and N-methyl-D-aspartate （NMDA） receptor antagonist, AP-5, orα-amino-3-hydroxy-5-methylisoxazole-4-propionic acid ...
هدف ما در این پایان نامه این است که با استفاده از معرفی ویژگی (*) برای فضای توپولوژی x، نشان دهیم که هرگاه x دارای این خاصیت و دو ویژگی زیر باشد: ویژگی (الف): هر زیرفضای شمارا فشرده از x با خاصیت (*) یک فضای دنباله ای یا یک فضای ap است. ویژگی ( ب ): x یک فضای دنباله ای یا یک فضای ap با ویژگی (*) است. آن گاه مفاهیم فشردگی، شمارا فشردگی و دنباله ای فشرده بر هم منطبق می باشند.
background: epidemic and endemic cholera is a major public health problem for many countries. aim of this study was to evaluate ap-pcr for investigation of clonal relatedness among the strains of vibrio cholerae recovered from an outbreak occurred in different parts of iran in 2005. methods: the study was conducted during the cholera outbreak occurred in some of provinces in iran in summer 2...
