Bluetooth is an ad hoc wireless technology that allows devices from lots of different manufacturers to communicate with one another when they come into range. Bluetooth is an short-range inexpensive wireless technology that eliminates the need of cabling between devices such as printers, cameras, personal digital assistants (PDAs), and handheld PCs. This paper outlines the recent advances of Bluetooth wireless technology in terms of version, range and data rates. The fundamentals of Bluetooth radio technology, ad-hoc networking, protocol stack and security issues are first introduced. The Bluetooth applications, air interface and the comparison of Bluetooth with other wireless communication technologies are presented in detail.

Stress is a person's physical, mental, or behavioral reaction to a "stressor" or situation. Every stressor is a result of a perceived threat (real or imagined). Stress is also the body's effort to respond to change. It can affect your ability to perform your job or fulfill commitments in your personal life and may cause health problems. Job and personal stressors are the two main causes for workplace stress. The National Institute for Occupational Safety and Health (NIOSH) defines job stress as "the harmful physical and emotional responses that occur when the requirements of the job do not match the capa-bilities, resources or needs of the worker". This can lead to health problems, lowered productivity, increased absenteeism, and job injury.- Geochemistry and Petrogenesis of Anorogenic(?) Granitoids of West Garo Hills, Meghalaya

The granite in Samingiri - Dilsekgiri area occurs as discordant, isolated pluton within the migmatitic terrain of West Garo Hills district, Meghalaya. The pluton is exposed over 140 sq km (18 km × 8 km). It exhibits structures of solid state and piecemeal stoping effect proximal to the contact and enveloped by a contact metamorphic aureole of albite-epidote-hornfels facies. Modally, it is biotite-monzogranite and biotite-syenogranite with minor biotite, chlorite, epidote and sericite and accessories like zircon, apatite, allanite, pyrite, magnetite and sphene. Geochemically, it is marked by restricted composition (69-76 wt% SiO2), high alkalies, low Ca, metaluminous to strongly peraluminous (Molar Al2O3/CaO+Na2O+K2O = 0.95-1.54), high FeO/MgO, high Ga/Al, high contents of Rb, Sr, Ba, Y, Zr and Ce and depleted in Ti and P. The field observation, mineralogical and geochemical aspects indicate the post-tectonic nature of West Garo pluton more like as A-type granite formed by partial melting of lower crustal blocks followed by low to moderate degree of fractional differentiation. Low Ca, alkaline nature and peraluminous character point to A-type nature of West Garo granite significantly different from other granites of Meghalaya Plateau. Rb-Sr age (616 ± 86 Ma) of granite, however, corresponds to widespread Middle to Upper Pan African activity, a thermal event prevailed during Late Proterozoic - Early Palaeozoic (500-800 Ma) period, manifested in the form of several granitic intrusions in the basement gneissic complex and the overlying Proterozoic metasediments of the Shillong Group in Meghalaya Plateau.Keywords
