The maximum entropy principle (MEP), which has been popular in the modeling of droplet size and velocity distribution in sprays, is, strictly speaking, only applicable for isolated systems in thermodynamic equilibrium; whereas the spray formation processes are irreversible and non-isolated with interaction between the atomizing liquid and its surrounding gas medium. In this study, a new model f...

Fruit flies (Diptera: Tephritidae) are among the most economically important pest species in the world, attacking a wide range of fruits and fleshy vegetables throughout tropical and sub-tropical areas. These species are such devastating crop pests that major control and eradication programs have been developed in various parts of the world to combat them. The array of control methods includes ...

We have studied the ignition of fuel sprays and simulated solid rocket fuels (SRF) by the photoignition of single wall carbon nanotubes (SWCNTs) with an ordinary camera flash. Our investigation includes the effect of solid additives such as aluminum nano-particles and solid oxidizers such as ammonium perchlorate (AP) on the photoignition characteristics. We have shown that by mixing CNT with ot...

© 2006. Research Information Ltd. All rights reserved DOI: 10.1564/17jun04 Abstract Insecticidal baits have been used to control grasshoppers and locusts since the 1880s. After the peak in the 1940s1950s, they were increasingly replaced by more economical dusts and sprays. Nowadays, baits are used on a regular basis in North America to control rangeland grasshoppers and Mormon crickets. A typic...

Periodic drought is one of the most serious hazards to young conifer plantations in several regions of this country. In the Lake States region, for example, droughts have occurred in four years of the past seven. Biologists have suggested that repellent substances sprayed on leaves of conifers to prevent rodent damage might, in addition, have a beneficial effect on survival during droughts. It ...

The aim of this review is to provide information regarding significant aspects and challenges in developing nasal sprays. This article outlined the relevant anatomy, physiology & biological, physicochemical pharmaceutical factors that must be considered during formulation development Nasal drug delivery system most preferable route than other routes administration as it gives rapid onset ac...
