Description
Nanoparticles are defined by the worldwide federation of national standards bodies, the International Organization for Standardization (ISO), as nanoobjects with
all external dimensions in the nanoscale, where the lengths of the longest andshortest axes of nanoobjects do not differ significantly . Though nanoscale is basically ranged from 1 to 100 nm, nanoparticles can be categorized by three size ranges: larger than 500 nm, between 100 and 500 nm, and
between 1 and 100 nm (European Commission, 2010). With respect to the size and the size distribution, nanoparticles may exhibit size-related intensive properties. If they are small enough to confine their electrons, they produce quantum effects and exhibit unexpected properties, for example, gold nanoparticles appear red in solution (see, for instance, Eustis and El-Sayed, 2006), and melt at much lower temperatures than that in slab form (Buffat and Borel, 1976). The high surface-area-to-volume ratio of nanoparticles provides the significant changes in properties related to contact/surface area, such as catalytic (Astruc, 2008),surface-enhanced plasmon resonance (Melaine et al., 2015), etc.

PHT 112: HIV AIDS Determinants, Prevention and Management
HIV is a lent virus, which is a class of viruses that attack the immune system. Lent viruses are in turn part of a larger group of viruses known as retroviruses. The name 'lent virus' literally means 'slow virus' because they take such a long time to produce any adverse effects in the body.

Project -is a temporary endeavor undertaken to accomplish a unique purpose.
• A project has three key characteristics:
(i). Temporary - It must have a beginning and an end.
(ii). Unique - thus producing a unique deliverable. In other words, the project must never have been done before, and it must have a well-defined purpose.
(iii). Progressively elaborate - that development occurs in steps and then continues in small increments, adding features and definition.
Project management -is the application of knowledge, skills, tools, and techniques to project activities in order to meet or exceed stakeholder needs and expectations from a project.
