Because of bifercation of states such as Andhra Pradesh and Telangana in India based on linguistic backgrounds of both states, the promotion of products in these two markets was become difficult in the context of personal selling. Sales force of these two states would confront some problems of language. A research is needed to identify the barriers of communication between sales force and customers in these two states....
Wireless Sensor Networks (WSNs) consist of a set of accurate devices called sensors or sensor nodes. These sensors are distributed within a certain area to perform some functions of surveillance or control in this environment, such as monitoring temperature, pressure, sound, movement, pollution or noise. Distributed sensors cooperate with each other to transfer the monitored data wirelessly to centralized computers or control centers which can handle and benefit from the transfered data for protection and doing the necessary studies. One of the most important and effective applications of WSNs is the monitoring environments and natural reserves to protect them from fire, flood, aggressors and extinction.
In this paper, researchers are building a proposed strong and effective system for monitoring and protecting the Ibex Reserve at Hotat Bani Tamim, Saudi Arabia. The propsed system is based on the wireless sensor networks’ technologies, advanced sensors and smart monitoring cameras in order to protect the wildlife inside the Ibex Reseve. In addition to prevent overfishing animals and birds, unfair cutting of trees and grasses, and help doing the necessary studies. The proposed system can be applied on the wildlife sanctuaries at Saudi Arabia (sixteen natural wildlife reserve)and three mariene protected. In addition to the availability of informations and evidences needed to make studies to protect them.

The relationship between the East and West and the adjustment to western traditions and mores are two major themes Alaa Al-Aswani discusses in his novels Emarrat Ya'copian (2002) and Chicago (2008).These novels are mainly concerned with the themes of clash of civilization, interracial relationships, cultural traumas and the westernized intellectual groups crisis of identity in their traditional societies. In these novels Al-Aswani not only give us a direct image of the Egyptian society but most of the time, in the background, appears the shade of another society, a society each of the characters dreams of living in: that is the country of peace, justice and egalitarianism. That ideal hoped society most of the time is cited as being the western society in which most of the fictional characters in the novels subject to study spent long periods of their lifetime. However; Al-Aswani challenges this belief. He argues that most of these characters end up as failures and that life in the west is not successful all the time....
In almost all of his fictional and dramatic works, Wole Soyinka criticizes and mocks the intellectual group for their passive inadequate responses to the decadent socio-political reality prevailing Nigeria in his realistic comments on injustice, filthiness, poverty and corrupt practices in business and politics. This appears clearly in his novel 'The Interpreters' which launches a supremely witty critique of the Nigerian society led by a corrupt, laughable, and self-hating elite. The few intellectuals in the novel ( Sagoe, Sekoni, Egbo, Bandele, Kola and Dehinwa) who attempt to change the ugly situation prevailing their country are portrayed as failures who instead of initiating reforms to the decadent system, degenerate into frivolity. This is the impression a first reading of Soyinka’s The Interpreters creates in readers through its fixed flat characters who only criticize and mock the sociopolitical reality surrounding them but after all cannot bring about positive change to it....
The term wireless networking refers to technology that enables two or more computers to communicate using standard network protocols and utilizing radio waves. With the rapid development of wireless networking, wireless sensor networks (WSNs) have been emerged which consist of large amount of small resource constrained devices; called sensors. S-MAC is a medium-access control (MAC) protocol designed for wireless sensor networks, it is different from traditional wireless MACs such as IEEE 802.11 in several ways such as energy conservation and self-configuration. A lot of protocols are designed to reduce energy consumption of the wireless sensor nodes. Periodic listen and sleep protocol, adaptive listen protocol and prolong listen protocol are examples of these protocols. In this book, a new S-MAC protocol named; "prediction S-MAC protocol" is proposed to improve the performance of the previous S-MAC protocols.Book Details:

With the rapid development of wireless networking and micro-electro-mechanical systems (MEMS), wireless sensor networks (WSNs) have been immerged. WSNs consist of large amount of small, low-end, resource constrained devices, called sensors. Since sensor nodes are usually intended to be deployed in unattended or even hostile environments, it is almost impossible to recharge or replace their batteries. One of the most important research issues in the wireless sensor networks is to extend the network lifetime by energy efficient battery management. So, there are a lot of approaches that are designed to reduce the power consumption of the wireless sensor nodes. In this paper; a new protocol named "prediction S-MAC protocol" is proposed to reduce the power consumption of the wireless sensor nodes and to improve their performance compared to the previous S-MAC protocols....
A wireless sensor node, being a microelectronic device, can only be equipped with limited power sources, e.g., batteries. Since wireless sensors are usually intended to be deployed in unattended or even hostile environments, it is almost impossible to recharge or replace their batteries. The lifetime of a sensor node is much dependent on its power consumption. Hence, energy efficiency is of highly concern to the wireless sensor networks design.
In this paper a prolong listening protocol is studied. This protocol is increasing both throughput and average node life while decreasing both average packet delay and average node power consumption compared to both periodic listen & sleep and adaptive listen protocols. A new protocol named prediction S-MAC protocol is proposed to improve the performance parameters of the existing S-MAC protocols. Simulation results show that prediction S-MAC protocol increases both throughput and average node life while decreasing both delay and average node power consumption compared to prolong listening protocol.
