In modern energetic propellant formulations, conventional plasticizers are being gradually replaced by energetic plasticizers having nitro, nitroamino, azido and other energetic groups. Energetic Plasticizers used to improve processing, mechanical properties and index of energy. Designer of propellant for decrease migration and improve safety factors in propellant’s formulation should to notice...
in this work, thermal degradation behavior of a fuel-rich energetic mixture containing epoxy binder was studied by thrmogravimetric analysis and differential scanning calorimetry under dynamic nitrogen atmosphere at different heating rates. variation of the thermal degradation activation energy of the mixture was evaluated by differential and integral isoconversional methods via akts software p...
this study was conducted to evaluate the effect of adding a commercial medicinal plant (mp) powder containing garlic (allium sativum) and thyme (thymus vulgaris) to diets that included olive pulp (op), on the performance and carcass characteristics of broiler chicks. a total of 240 day old male ross-308 broiler chicks were allocated into six iso-nitrogenous and iso-energetic dietary groups with...
the behavior of nanoscale energetic materials is quite different from micronsized energetic materials inmany ways. recently, some techniques such as sol-gel method, high speed air impaction and vacuum codeposition have been employed to obtain nanoscale energetic materials. however, only few attentionswere paid to nanoscale energetic materials because of the fabrication difficulty. in this paper...
AIMS Development of metabolic syndrome is associated with impaired cardiac performance, mitochondrial dysfunction and pro-inflammatory cytokine increase, such as the macrophage migration inhibitory factor MIF. Depending on conditions, MIF may exert both beneficial and deleterious effects on the myocardium. Therefore, we tested whether pharmacological inhibition of MIF prevented or worsened meta...
an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...
Recent approach in the field of design and manufacture of the propellant and explosive has led to the use of energetic ingredients. Introduction of energetic plasticizers as a replacement of commonly used inert plasticizers is another approach to improve the energy level of propellants. In this meantime, energetic compound based on organic azids were attracting a lot of attention. The poor mech...
the objective of present study was to determine the effects of β-mannanase-based enzyme (hemicell®) on productive performance and egg quality in diets containing graded levels of whole date waste (wdw) fed to laying hens. a total of 336 hy-line leghorn hens after production peak were randomly divided into 56 cages. eight iso-energetic and iso-nitrogenous experimental diets in a 4 × 2 factorial ...
Gamma-ray bursts (GRBs) are known to be highly collimated events, and mostly detectable when they seen on-axis or very nearly on-axis. However, GRBs can from off-axis angles, the recent detection of a short GRB associated gravitational wave event has conclusively shown such scenario. The observer viewing angle plays an important role in observable spectral shape energetic events. We present num...
Formation of waste water from military industries and also accumulating of energetic materials from incomplete explosion could cause to penetration of energetic materials to ground and underground waters. The issues of this penetration could be catastrophe. Therefore, proper manners, in order to infiltration of these waters, must to be implemented. Attention to variety energetic materials, best...
