Optimizing the number, distribution, and accessibility of Brønsted acid sites in zeolite-based catalysts is of a paramount importance to further improve their catalytic performance. However, it remains challenging to measure real-time changes in reactivity of single zeolite catalyst particles by ensemble-averaging characterization methods. In this work, a detailed 3D single molecule, single tur...

a random 12 mers phage library was used to screen a pool of immunoglo¬bulin fractions obtained from vitiligo patients. subsequent to panning experiments, a panel of affinity selected phage from vitiligo patients were obtained. this panel was tested using an elis a for their reactivity with pooled sera from patients and normal controls. among the 16 randomly selected clones, two of clones showed...

Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectiv...

This paper aims to illustrate how the combination of Network Analysis and Futures Studies becomes a powerful instrument for envisioning and analyzing futures and social change. The study of three cases shows network analysis becoming an analytical tool in futures studies while, at the same time, acquiring the dimension of change and dynamics steaming from the futurist perspective.

Which side are you on? Scanning transmission X-ray microscopy is used for the first time to elucidate the coordination and distribution of aluminum in industrial-relevant zeolites at the single-particle level. Extended regions of a few hundred nanometers, rich in higher aluminum coordination environments, are heterogeneously embedded within the zeolite particle, before and after a steaming post...

The individualistic effect of unit operations of production, at household level, on some antinutritional factors in selected cowpea-based food products (moin-moin, akara, and gbegiri) was investigated. Four cowpea types (IT93K-452-1, IT95K-499s-35, IT97K-568-18, and market sample) were used for the study, whereas the three traditional food products were produced from each of the cowpea types, r...

StreamTo uses tamper resistant hardware tokens to generate the key stream needed to decrypt encrypted streaming music. The combination of a hardware token and steaming media effectively brings tried and tested PayTV technology to the Internet. We provide a security analysis and present two prototype implementations with a performance assessment, showing that the system is both effective and eff...
