Particle packing optimization is a philosophy that has evolved over the years. Its use in concrete proportioning helped creating denser and stronger mixes. Numerous theories models have course of time to optimize concrete. Out which Modified Andreassen curve found its practical application optimizing high-performance The main objective study was different particle their effects on mortar mixes ...

Several agri-environment schemes aim to improve pollinator diversity and abundance, including the sowing of wildflower areas. These seed mixes are often either low in floral target few species (mainly social bees), or high but with limited evidence good establishment component species. In order support a greater wild bees farmland, we need more diverse mixes, containing shown wide insect pollin...

It has long been understood that anonymity and efficiency are conflicting design criteria in the design of communication systems. Strongly anonymous systems such as those using Chaum's Mix networks can impose significant bandwidth and latency overheads, while other systems typically attain better performance at the expense of relaxing their resistance to traffic analysis. This paper describes a...

Sequencing in less than four lanes on a gel, using only one fluorescent label for the four bases (without variations in electrophoretic mobilities or problems with spectral overlap) in one tube was introduced in (1). In that process T7 DNA polymerase and buffer containing magnesium ions were used. By adjusting the ddNTPs ratios the sequence is deduced from the peak magnitudes corresponding to t...

The performance requirements of the concrete of containment structures are mainly radiological protection, structural integrity and durability, etc. For this purpose, highperformance heavy density concrete with special attributes can be used. The aggregate of concrete plays an essential role in modifying concrete properties and the physico-mechanical properties of the concrete affect significan...
