The possibility of retrieving size distribution of aerosol particles in the stratosphere by measuring the extinction of solar radiation traversing the aerosol medium at two different wavelengths is explored in this work. This paper presents a parametric study of the effects of size distribution and composition of stratospheric aerosols on the value R, the ratio of extinction of solar radiation ...

1. Describe the range of symptoms and severity of postpartum depression (PPD). 2. Delineate the appropriate, validated screening tools for detecting PPD. 3. List the percentage of women in whom PPD is detected within the current standard of practice. 4. Describe the effects of PPD on maternal-infant interactions and parental attitudes and behaviors. 5. Characterize the method of determining opt...

The Strategic National Risk Assessment (SNRA) was executed in support of Presidential Policy Directive 8 (PPD-8), which calls for creation of a National Preparedness Goal, a National Preparedness System, and a National Preparedness Report. Specifically, national preparedness is to be based on core capabilities that support ―strengthening the security and resilience of the United States through ...

wage-loss replacement rate increases with the duration of disability, with PPD claimants doing the best. Of course, it should be pointed out that, under the assumption that the PPD claimants have lifelong (or permanent) impairments, their earnings losses will continue far beyond the five-year mark. This in turn will serve to lower the replacement rate since nearly all workers’ compensation paym...

In this paper, I develop a duopoly location model of differentiated products in which consumers’ product preferences vary positively with product prices. The level of preference price-dependence (“PPD”) is allowed to vary across consumers. I find that equilibrium prices increase with the PPD level of the marginal, or “just indifferent,” consumer, but are not influenced by the PPD levels of othe...

Leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. Determining drying characteristics of leather is vitally important so as to optimize the drying stage. This paper describes an analytical way for determination of the drying characteristics of leather. The model presented, is based on fundamental heat and mass tra...
