Identifying the Barriers to Iran’s Saffron Export by Using Porter’s Diamond Model
Saffron is an important export product of Iran. Saffron role as an agricultural export product is now obvious worldwide. It is important to identify the barriers to Iran’s Saffron export in order to maintain Iran’s position as the world’s biggest ...

The growing demand for lightweight, nontoxic, and multifunctional gamma shielding materials has intensified efforts to find alternatives to conventional lead and aluminum‐based protectants. In this work, we develop epoxy quartz fabric composites reinforced with cobalt chloride (CoCl2) microparticles, fabricated via hand lay‐up with varying filler ...

Axial collapse behavior of stainless steel circular tubes with thin walls in diamond mode
As a commonly used axial crushing energy-absorbing component, the theoretical model of the diamond mode of thin-walled circular tubes is less successful than the ring mode.

High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...

Carbon nanomaterial‐reinforced epoxy composites exhibit pronounced piezoresistive behavior, enabling intrinsic damage sensing under cyclic and fatigue loading. This review critically compares carbon nanotube and graphene systems, correlating filler content, percolation threshold, and gauge factor with sensing stability and damage evolution.

Slow ground motion modelling of diamond [PDF]
The need for high stability in third generation light sources has produced strict requirements on the design of the foundations. The specification for the concrete floor stability is a critical task, which can have a major cost impact. A careful assessment of the effects of slow ground motion on the accelerator is therefore required.

Guessing models and generalized Laver diamond [PDF]
We analyze the notion of guessing model, a way to assign combinatorial properties to arbitrary regular cardinals. Guessing models can be used, in combination with inaccessibility, to characterize various large cardinals axioms, ranging from supercompactness to rank-to-rank embeddings.
