The retinal structures of the compound eyes of insects are being investigated as par t of a comparative study of the s tructure and biochemistry of visual organs (1 5). T he compound eye of the insect is composed of numerous ommatidia , each of which consists of f rom four to eight re t inula cells. Each re t inula cell contains a differentiated structure, the rhabdomere , a photoreceptor . The...

The title compound, C(16)H(24)O(3), was synthesized from ilicic acid which was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused six-membered rings both in chair conformations. In the crystal, mol-ecules are linked into chains running parallel to the a axis by O-H⋯O hydrogen bonds.

Inula britannica L., family Asteraceae, is used in traditional Chinese and Kampo Medicines for various diseases. Flowers or the aerial parts are a rich source of secondary metabolites. These consist mainly of terpenoids (sesquiterpene lactones and dimmers, diterpenes and triterpenoids) and flavonoids. The isolated compounds have shown diverse biological activities: anticancer, antioxidant, anti...

One of the most prominent features on gravity and aeromagnetic maps of the United States is a series of major, generally linear anomalies that extend from central Kansas to Lake Superior and then turn southward into central Michigan (Figures 1, 2). This system of anomalies clearly reflects major geological features, and as such it must represent a very significant episode in the history of the ...

O objetivo deste artigo é analisar os recursos imersivos presentes na obra de Realidade Virtual (RV) “Henry”, dos produtores da empresa Oculus Story Studio, vinculada à Oculus/Meta, Ramiro Lopez Dau e Saschka Unseld, com base no modelo teórico proposto por Ermi Mäyrä (2005). Para tanto, inicialmente apresentamos uma breve introdução sobre mídias dotadas tecnologias seus usos construção narrativ...
