drought stress is the most limiting factor of agricultural production through the world. to evaluate the effect of super absorbent and humic acid to reduce drought stress in sugar beet production, a strip split plot arrangement based on randomized complete block design with three replications was conducted at research field of faculty agriculture, ferdowsi university of mashhad, iran during gro...

The dynamic aperture caused by persistent-current nonlinear field errors is an important concern in the design of superconducting hadron storage rings. The HERA proton ring is the second superconducting accelerator in operation. In this lecture note, its measured dynamic aperture is compared with that inferred from comprehensive tracking studies. To understand the difference between prediction ...

The use of super-wide angle and fish-eye lenses causes strong distortions in the resulting images. A methodology for the correction of distortions in these cases using only single images and linearity of imaged objects is presented in this work. Contrary to most former algorithms, the algorithm discussed here does not depend on information about the real world co-ordinates of matching points. M...

We perform numerical simulations of a new proposal of laboratory experiment that would allow the transformation of a classical °uid into a quantum-type (super)°uid through the application of a generalized quantum potential. This quantum potential is simulated by using a real time retroactive loop involving a measurement of density, a calculation of the potential in function of the measured dens...

Great expectations and promises rest on interdisciplinarity in nanoscale research. Yet, although many science and engineering disciplines actually began to engage in this field, it is only poorly understood what interdisciplinarity actually is and what factors hinder and promote it. Part I provides an introduction to interdisciplinarity, its cognitive and social elements, and its related concep...
