Influence lines have important application for the design of structures
that resist large live loads. In this chapter we will discuss how to draw
the influence line for a statically determinate structure. The theory is
applied to structures subjected to a distributed load or a series of
concentrated forces, and specific applications to floor girders and
bridge trusses are given. The determination of the absolute maximum
live shear and moment in a member is discussed at the end of
the chapter.

The orbital region
The orbits are a pair of bony cavities that contain the eyeballs; their associated muscles,
nerves, vessels, and fat; and most of the lacrimal apparatus. The orbital opening is
guarded by two thin, movable folds, the eyelids. 
 

Just to give you a little excitement about C++ programming, we going to give you a small conventional C++ Hello World program.
C++ is a super set of C programming with additional implementation of object-oriented concepts.

 Record Base (or Base Plate) Record bases (temporary denture base) defined as: A temporary form representing the base of denture to which occlusion rims are attached. It is used in recording maxilla-mandibular relations and in the arrangement of teeth. Uses: 1. Support of the occlusal rims. 2. Recording maxillomandibular relation. 3. Carry of artificial teeth to perform try in procedure. 4. Gives an idea about the contour, extent and esthetics of the denture. Materials used in the Construction of Record Base:- 1. Shellac record base. 2. Hot curing acrylic resin. 3.

Class V Tooth Cavity Preparations for Amalgam Restoration Class V lesion is present on the gingival third of facial and lingual surfaces of all teeth. Amalgam is not indicated for anterior teeth except when esthetics is of no concern, for example in very aged patients. Causes of Cl. V cavitation: 1. Dental caries. 2. Erosion: tooth loss caused by non-bacterial acids (Fig. 1). 3. Abrasion: tooth loss at gingival third due to mechanical action...............
