PREDICTING OF ELDERLY POPULATION STRUCTURE AND DENSITY BY A NOVEL GREY FRACTIONAL-ORDER MODEL WITH THETA RESIDUAL OPTIMIZATION: A CASE STUDY OF SHANGHAI CITY, CHINA

Abstract Background Accurately predicting the future development trend of population aging is conducive to accelerating the development of the elderly care industry.This study constructed a combined optimization grey prediction model to predict the structure and density of elderly population.Methods In this paper, a GT-FGM model is proposed, which

The present study investigates the microfacies and source rock potential of the Eocene Nammal Formation in the Nammal Gorge Section, western Salt Range, Pakistan.The Nammal Formation consists of light grey to creamy color limestones, olive green to grey shales and light grey marls.Twelve rock samples of limestone were collected for microfacies anal

Volcanic eruptions through crater lakes often generate lahars, causing loss of life and property.On Ambae volcano, recent eruptive activities have rather tended to reduce the water volume in the crater lake (Lake Voui), in turn, reducing the chances for outburst floods.Lake Voui occupies a central position in the summit caldera and is well enclosed

Wolbachia are required for filarial nematode survival and fertility and contribute to the immune responses associated with human filarial diseases.Here we developed whole-mount immunofluorescence techniques to characterize Wolbachia somatic and germline transmission patterns and tissue distribution in Brugia malayi, a nematode responsible for lymph

In order to make the most of the digital outsourced documents, based on new technologies (e.g.: 3D LASER scanners, photogrammetry, etc.), a new IEC Mains Power Lead approach was followed and a new ad hoc information system was implemented.The obtained product allow to the final user to reuse and manage the digital documents providing graphic tools
