Mechanisms of uptake of rare earth elements (REEs) were investigated, particularly those by REE accumulator species (autumn fern). Rare earth elements are practically insoluble under natural conditions, suggesting some unknown mechanism in REE accumulator species. In the present investigation, two notable phenomena were observed. (I) Concerning the ionic-radius dependence of REE uptake by leave...

Although technology advancement can pack more and more physical registers in processors, the numbers of architectured registers defined by the instruction set architectures (ISAs) remain relatively small on most modern processors. Exposing more architectured registers to compilers and programmers can improve the effectiveness of compiler optimization and the quality of code. However, increasing...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...

Cryptographic accumulators allow to accumulate a finite set of values into a single succinct accumulator. For every accumulated value, one can efficiently compute a witness, which certifies its membership in the accumulator. However, it is computationally infeasible to find a witness for any nonaccumulated value. Since their introduction, various accumulator schemes for numerous practical appli...

A compressor was developed using R32 which was a low GWP R32 refrigerant for coping with global warming. However, there is a tendency for vibrations of a compressor to also increase because the circulation of refrigerant increases according to specification for using R32 refrigerant. Since large vibrations of a compressor causes outdoor units to generate solid propagation sound, there is a need...

A notation is developed which permits space and time efficiemcy comparisons of four basic computer architectures in use today for executing Fortran-style assignment statements. From the com~arisona, we discover that a suitably designed l-address archit.cture (one accumulator machine) outperforms toe other architectures in speed of execution and in encoded size ~ compiled Fortran statements. The...
