Soybean agglutinin (SBA) represents the anti-nutritional molecule in soybean. This agglutinates erythrocytes of several animal species. The specific binding SBA to glycoprotein c...
For the first time an ordered mesoporous silica (Fe-Al-SBA-15) with catalytically active isolated Fe surface species for the hydroxylation of benzene with nitrous oxide is prepared by introduction of Fe3+ in the synthesis gel of Al-SBA-15.
پورفیرین ها یک ترکیب ماکروسیکل هترو اتم می باشند که نقش مهمی در زندگی موجودات زنده ایفا می کنند. به طور مثال هِم موجود در ساختار هموگلوبین که مسئول انتقال اکسیژن در خون است و کلروفیل که رنگدانه فتوسنتزی گیاهان به شمار می رود، نوعی پورفیرین می باشند. ساختار مولکولی پورفیرین ها ، متشکل از چهار واحد پیرولی است که به وسیله پل های مِتین به هم متصل شده اند. این ساختار در سال 1912 توسط کوستر پیشنهاد شد،...
Extracellular recordings were obtained from the ganglion cell (GC) layer during correlated spontaneous bursting activity (SBA) in the immature turtle retina. Pharmacological agents were bath-applied, and their effects on burst and correlation parameters were determined. SBA requires synaptic transmission. It was blocked in the presence of curare and mecamylamine, two cholinergic nicotinic antag...
A family of heterogeneous catalysts has been prepared by employing different strategies: firstly by direct reaction or grafting of titanium, zinc, aluminium and magnesium precursors with dehydrated SBA-15 and secondly by reaction of the metallic derivatives with a hybrid SBA-15 mesoporous material, which possesses a new covalently bonded linker based on an amino alcohol chelate ligand. These ma...
Current cloud service offerings, i.e., Software-as-a-service (SaaS), Platform-asa-service (PaaS) and Infrastructure-as-a-service (IaaS) offerings are often provided as monolithic, one-size-fits-all solutions and give little or no room for customization. This limits the ability of Service-based Application (SBA) developers to configure and syndicate offerings from multiple SaaS, PaaS, and IaaS p...
Consistent resting brain activity patterns have been repeatedly demonstrated using measures derived from resting BOLD fMRI data. While those metrics are presumed to reflect underlying spontaneous brain activity (SBA), it is challenging to prove that association because resting BOLD fMRI metrics are purely model-free and scale-free variables. Cerebral blood flow (CBF) is typically closely couple...
Developing and deploying Service-based Applications (SBAs) using different Software-as-a-service (SaaS), Platform-as-a-service (PaaS) and Infrastructure-as-a-service (IaaS) offerings from multiple providers in the cloud is still not possible, since current cloud service offerings are often provided as monolithic, one-size-fits-all solutions and give little or no room for customization. This lim...
An inorganic-organic silica material (SBA-15-1), prepared by immobilization of the naphthalimide derivative within the channels of the mesoporous silica material SBA-15, is characterized by several spectroscopic methods. SBA-15-1 can be used as a chemical sensor for detecting and removing Hg(2+) in a heterogeneous system. The fluorescence enhancement of SBA-15-1 was attributed to the formation ...
SBA-15 was utilized as mesoporous support for the dispersion of vanadium phosphate (VPO) compounds. Loading of SBA-15 with VPO compounds was found to be accompanied by decreasing (29)Si MAS NMR signals of Q(2) (Si(2Si,2OH)) and Q(3) (Si(3Si,1OH)) silicon species, which indicates coverage of the mesoporous support by the guest compounds. The (51)V MAS NNR spectra of the activated VPO/SBA-15 cata...
