EXTERNAL VIEW SURFACE VIEW OF HEART Position‚ Shape and Size of the Heart: The human heart is located between the lungs in the thoracic cavity (i.e. it is not situated on the left side of the chest). The heart is a hollow‚ fibro-muscular organ and is somewhat conical in shape. It is about the size of one’s fist‚ measures about 12 cm in length and 9 cm in breadth. Its weight is about 300 g in an adult. The heart is enclosed in pericardium (a double- layered membranous sac). It protects the

Believe it or not‚ this is determined by just three camera settings: aperture‚ ISO and shutter speed (the "exposure triangle"). Mastering their use is an essential part of developing an intuition for photography. UNDERSTANDING EXPOSURE Achieving the correct exposure is a lot like collecting rain in a bucket. While the rate

Female reproductive system of earthworm- It consists of following parts: 1. Ovary 2. Oviducal funnel 3. Oviducts 4. Female genital aperture 5. Spermathaceae 1. Ovary- They are the white lobed structures which are present in the intersegment of 12/13. They consist of ova secreting cells. The ova are usually generated by the process of oogenesis. They are generally arranged on the basis of maturation. The matured ones are contained in the distal end whereas the immature ones

What are the different types of aperture.? i) Effective aperture. ii). Scattering aperture. iii) Loss aperture. iv) collecting aperture. v). Physical aperture. 7.Define different types of aperture.? Effective aperture(Ae). It is the area over which the power is extrated from the incident wave and delivered to the load is called effective aperture. Scattering aperture(As.) It is the ratio of the reradiated power to the power density of the incident wave. Loss aperture. (Ae). It is the area of the antenna

HYDRAULICS IN MISSILES Nowadays‚ the electro-hydraulic actuator plays an important role in some modern tactical missiles. High power‚ great robustness and high tracking precision are the most significant demands for the missile actuator. Therefore an advanced method of active disturbance rejection control (ADRC) is presented aiming at the dynamics of the system are highly nonlinear and have large extent of model uncertainties‚ such as tremendous changes in load. Firstly‚ a novel ADRC controller

1. Examine the various search patterns investigators can use to systematically search crime scenes for evidence. Line/strip search-method used by one or two investigators who walk in straight lines across the crime scene. This method is best used in scenes where the boundaries are well established. Grid search-method employed by two people who perform overlapping line searches forming a grid. This method is very thorough. Spiral search-employs one person where the investigator moves either in

look more interesting. The third thing I have learned in photography is about the exposure triangle consisting of the aperture‚ the ISO‚ and the shutter speed. The aperture is the measurement that defines the size of the opening in the lens and can be adjusted to control the amount of light reaching the digital sensor. In the third project‚ we viewed the differences in aperture by keeping the shutter speed and ISO the same while setting the
