The epigenetic alterations like histone modifications , DNA methylation and others remarkable categories including nucleosome remodeling and RNA mediated targeting have been strongly investigated recently .In this way , beside the notable importance of DNA methylation ,the histone modifications are the most important issues in the tumorogenesis and cancer progression. Moreover...
This paper presents the results of a recent project of IKCo’s research center to modify Paykan 1600’s rear suspension mechanism with the purpose of improving comfort, stability and handling qualities. The car was originally equipped with a solid rear axle with leaf springs. By replacing the original mechanism with a three-link mechanism with panhard bar and coil springs, the ride comfort and ha...
Mesoporous silica nanoparticles with unique structure (SBA-15) were synthesized and modified by [3-(2-Aminoethylamino) propyl] trimethoxysilane (AEAPTMS). The synthesized nanoparticles were characterized by TGA, N2 adsorption, SEM, FTIR, CHN elemental analysis. The total weight loss for the modified SBA-15 is 15.2% and thermal analysis reveal...
classical xerogels are robust, inexpensive and nontoxic materials with low-ordered nanoporous structures. in water streams where the ph is higher than the point of zero charge, the surface of classical xerogels such as tetraethoxy orthosilan (teos) xerogel is negatively charged. it was assumed that a xerogel can work as a strong adsorbent for metal ions without further modification. therefore, ...
mesoporous silica nanoparticles with unique structure (sba-15) were synthesized and modified by [3-(2-aminoethylamino) propyl] trimethoxysilane (aeaptms). the synthesized nanoparticles were characterized by tga, n2 adsorption, sem, ftir, chn elemental analysis. the total weight loss for the modified sba-15 is 15.2% and thermal analysis revealed that 1.5 mmol aeaptms/1g sba-15 had been grafted...
Abstract The red clay is widely distributed in Guizhou province, which characterized by high natural moisture content, difficult compaction and serious shrinkage crackingin, phosphogypsum discharged for 5 million tons every year province. For the sake of effectively reducing accumulation phosphogypsum, mixtures were prepared with cement as a curing agent mass ratios to 1:1, 1:2 1:3 (low content...
Bulk of various astronomical observations black holes suggest that virtually all observed can be primordial origin. A modified mechanism the hole formation is described. universal log-normal mass spectrum with a mean around $$ \sim 10{{M}_{ \odot }}$$ predicted by this strongly confirmed LIGO/Virgo gravitational waves from coalescing binary holes.
