in this paper, a new design of optical channel drop filter based on two- dimensional photonic crystal ring resonators with triangular lattice is proposed. the rods of this structure is silicon with the refractive index nsi=3.46 and the surrounding environment is air with the refractive index of nair=1.the widest photonic band gap obtains for the filling ratio of r/a = 0.2. the filter’s transmis...

New technologies are crucial in dealing with the problem of air and water pollution, which is an increasingly important issue with serious health and environmental consequences. Adoption of environmentally friendly technologies can be slow if the new technologies are not superior in terms of the firms’ private incentives, if firms have long equipment replacement cycles, or if firms do not have ...

This paper uses thunderstorm simulations, varying properties of thunderstorms consistent with the Southeast and Northeast U.S., in an attempt to explain the differences in Hg deposition between the regions. The model analyses are useful, explained thoroughly, and well-planned. However, the paper is essentially a model parameter space exploration for soluble tracer scavenging, and the conclusion...

This study provides the first systematic review of different marketing strategies used for promoting SMEs in Pacific Island Countries (PICs). Literature published high-ranked management journals was reviewed this area using PRISMA guidelines between 2000 to 2020. The identifies three major communication useful PICs: digital strategies, market orientation and experience based strategies. Further...

Approaches for the development of disease-resistant butternut (Juglans cinerea L.) are reviewed. Butternut is a threatened fine hardwood throughout its natural range in eastern North America because of the invasion of the exotic fungus, Sirococcus clavigignenti-juglandacearum Nair, Kostichka and Kuntz, which causes butternut canker. Early efforts were made to identify and collect putatively res...
