background: among all cancers, malignancies of gastrointestinal tract are the most common cancer among iranian population. dietary behavior is thought to be the most important risk factor in gastric cancer. fear and perceived severity are two important constructs of the protection motivation theory (pmt). despite the evidence of the impact of these two constructs in modifying dietary habits aga...

We have developed very efficient suicide functions for biological containment based on the lethal Escherichia coli relF gene. The suicide functions are placed in duplicate within a plasmid and arranged to prevent inactivation by deletion, recombination, and insertional inactivation. The efficiency of this concept was tested in a plasmid containment system that prevents transfer of plasmids to w...

“Intellectual property protection is important, but, almost of necessity, imperfect. It is harder and therefore more costly to define than conventional property, and by the same token, it is costlier to enforce intellectual property rights. In some cases, the inventor gets more than his marginal contribution, in other cases, less. Intellectual property protection strengthens dynamic efficiency ...

Well-resolved air–sea interactions are simulated in a new ocean mixed-layer, coupled configuration of the Met Office Unified Model (MetUM-GOML), comprising the MetUM coupled to the Multi-Column K Profile Parameterization ocean (MC-KPP). This is the first globally coupled system which provides a vertically resolved, high near-surface resolution ocean at comparable computational cost to running i...

Abstract Conservation decision-makers and practitioners increasingly strive for efficient equitable outcomes people nature. However, environmental management programs commonly benefit some groups of more than others, very little is known about how efforts to promote equality (i.e. even distributions) equity proportional trade-off against efficiency total net outcome per dollar spent). Based on ...

A comprehensive discussion of feasible strategies for sustainable energy supply is urgently needed to achieve a turnaround of the current energy situation. The necessary fundamentals required for the development of a long term energy vision are lacking to a great extent due to the absence of reasonable long term scenarios that fulfill the requirements of climate protection and sustainable energ...

A new anti-corrosion compound, Melamine Formaldehyde (MF), was formulated by the addition of proper amount of formaldehyde to melamine under specific conditions. This compound was mixed with a novel nano powder, which was extracted from corn cob ash containing SiO2 particles, in order to improve its corrosion inhibition efficiency. This inhibitor provides a high level of protection f...

Integrated satellite-terrestrial networks can improve both the service coverage and spectral efficiency in spot-beam-based mobile satellite service system (MSS). In an integrated satellite-terrestrial network, MSS frequency is reused in both satellite spot beams and complementary ground component (CGC). Due to reuse of frequency, co-channel interference is present in both intra-component (betwe...
