The study mainly focuses on the use of Golden Ratio and Fibonacci sequence. connection between them can be clearly visible in nature. With help sequence scientists have solved many mysteries related to Everything that is around us somehow or other depends numbers, Ratio, Some examples are –Flower petals- Lily, Rose, Daisy, Marigold, Sunflower, Iris, Buttercups, wild rose, larkspur Trillium, Blo...

Flower image retrieval is a very important step for computer-aided plant species recognition. In this paper, we propose an efficient segmentation method based on color clustering and domain knowledge to extract flower regions from flower images. For flower retrieval, we use the color histogram of a flower region to characterize the color features of flower and two shape-based features sets, Cen...

Article history: Received on: 19/11/2013 Revised on: 10/12/2013 Accepted on: 05/03/2013 Available online: 27/04/2014 The neuropharmacological activity of different doses (100, 200, 400 mg/kg/p.o.) of petroleum ether (SIP), methanolic (SIM) and aqueous extract (SIA) obtained from Sphaeranthus indicus Linn were studied in mice. Sphaeranthus indicus was evaluated for its effect on motor coordinati...

Loading conditions and complex geometry have led the cylinder heads to become the most challenging parts of diesel engines. The aim of this study is to compare the distribution of temperature and stress in the aluminum and magnesium cylinder heads under thermo-mechanical loads. The three-dimensional model of the cylinder heads was simulated in abaqus software and a two-layer viscoplasticity mod...

Flower color variation among plant populations might reflect adaptation to local conditions such as the interacting animal community. In the northwest Iberian Peninsula, flower color of Gentiana lutea varies longitudinally among populations, ranging from orange to yellow. We explored whether flower color is locally adapted and the role of pollinators and seed predators as agents of selection by...

The tendency for flower longevity to increase with altitude is believed by many alpine ecologists to play an important role in compensating for low pollination rates at high altitudes due to cold and variable weather conditions. However, current studies documenting an altitudinal increase in flower longevity in the alpine habitat derive principally from studies on open-pollinated flowers where ...

This paper describes an interactive presentation that introduces the Talking Heads website, which was originally proposed at the AVSP'97 meeting in Rhodes, Greece. Talking Heads is an effort to bring together information from a wide range of sources. The site provides interactive access to multimodal material in both its original form and as summarized by us. In addition, the authors have provi...

Purpose: To evaluate the phytochemical profile as well as in vitro antioxidant, iron-chelating, and antiglucosidase activities of Typha domingensis Pers. (Typhaceae) Methods: Total polyphenols, flavonoids, hydroxycinnamic acids, and pro-anthocyanidins in the respective aqueous extracts of male and female flowers, and fruit of T. domingensis were determined by established procedures. Antioxidant...

C oncussion, or mild traumatic brain injury (MTBI), continues to occupy the center stage in sports medicine. The relationship between contact sports and degenerative central nervous system diseases—such as dementia, amyotrophic lateral sclerosis, depression, and chronic traumatic encephalopathy (CTE)—remains unclear and thus deserves focused investigation as researchers probe for clinical answe...

The growth in the human population poses a wide range of serious threats to the planet. Many have been highlighted but the political and social response has been ineffective in many countries. A special issue of the Philosophical Transactions of the Royal Society, published online, provides us “with an intellectual feast”, even though the papers “will leave a bitter taste in the mouth afterward...
