“Mirage: An optical effect that is sometimes seen at sea‚ in the desert‚ or over a hot pavement‚ that may have the appearance of a pool of water or a mirror in which distant object are seen inverted‚ and that is caused by the bending or reflection of rays of light by a layer of heated air of varying density.”(Merriarn-Webster’s Medical Dictionary) Imagine yourself walking alone in the desert‚ you haven’t drink any water for a long time‚ you were tired‚ thirsty and exhausted. Suddenly‚ there was

Experiment 4.14 Portal Frame ( Plastic Bending of Portals ) AIM : To compare the ability of the portal frame to resists vertical and horizontal loadings. DESCRIPTION: Figure 1 shows the Plastic Bending of Portals experiment set up in a Test Frame. The Plastic Bending of Portals experiment consists of a specimen steel portal frame held firmly at the bottom corners by two fixing blocks (ensuring an encastre fixing). Two load cells load the specimen frame by wires and adjustable

Torsion- twisting of the embryo along the left-right axis (similar to the twist of the body when a golfer swings at the ball). MOST prominent in the 48-hour chick embryo Flexion- bending of the embryo along the anterior-posterior axis. In amniotes the tip of the head bends towards the heart. Types of flexion: cranial flexion‚ cervical flexion‚ pontine flexure‚ dorsal flexure‚ caudal flexure. ^Cervical flexure- ventral bend in embryo at transition between myelencephalon and spinal cord ^Dosal Flexure-

The results of the experiments carriedout for the degradation of fabric dyes from aqueous solution using Chara and Chara beads are discussed below.Various analytical techniques like UV-Vis‚ FTIR spectroscopy were used to confirm the decolorization as UV-Vis spectroscopy; FT-IR spectroscopy and toxicity bioassay were truly used [14]. Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]

The required diameter for the round member AB to resist only the bending action of the force P (use a factor of safety F.S.=2). The diameter of the pin C‚ also made of A-36 steel‚ so it acts as a fail-safe mechanism to limit the loading of the member CD to 75%
