آنکھ سے دور سہی دل کے قریں رہنے دے

آنکھ سے دُور سہی، دل کے قریں رہنے دے
میری ہر سانس میں تو خود کو مکیں رہنے دے

میں کہ اک عکس ہوں گمنام سا پس منظر ہوں
کب کہاں کیسے کسی طور کہیں رہنے دے

اک نظر مجھ پہ مرے ماہِ منیر ایسی ہو
کب طلب میں نے کیا زر یا نگیں، رہنے دے

میں ہوں اس قافلۂ عشق سے بچھڑا راہی
میرا کب ٹھور ٹھکانہ ہے کہیں، رہنے دے

تجھ سے منسوب ہوئی، تجھ سے ہی منسوب رہوں
غیر کے آگے جھکے گی یہ جبیں، رہنے دے

دل میں یا آنکھ میں یا دستِ حنائی میں فضاؔ
تیری مرضی ہے جہاں چاہے، وہیں رہنے دے

The Impact of Nicotine and Social Drinking Behavior and Brain Function

Nicotine acts on nearly every Physiological System of the human body. The effects of nicotine on the Peripheral nervous system have been extensively studied and are now quite well understood. The effects of nicotine on the central nervous system are more complex, and our understanding of these effects is limited. The Pharmacokinetic and Pharmacodynamics of nicotine, with an emphasis on the Psychopharmacological basis of nicotine dependence. In South America, seeking for psychoactive effects of nicotine might be as old as the origin of horticulture, beginning some eight thousand years ago present Ritual tobacco was used in shamanism aimed to achieve acute nicotine intoxication, which induced in the shamans’ catatonic states representing symbolic death. The effect of large doses of nicotine on the autonomic and central nervous system gave the impression of a gradual death of the shaman, who then returned miraculously to life (Wilbert 1987). Regular, moderate use of nicotine alone or in combination is a well-known, widely established and loved practice of men and women both. Despite, health consequences of these pharmacological agents, people continue, quite persistently, to consume these substances and afford much value to the pleasure of a regular intake.

Shortest Path Tree Scaling Hierarchical Power Efficient Routing for Wireless Sensor Networks

In the domain of Wireless Sensor Networks (WSN) the primary issue is the power awareness. The major energy resources of Wireless Sensor Networks are small batteries of the sensor nodes. These small batteries have limited energy. Generally, the users are unable to access these small sensor nodes once they are deployed. Hence it is impossible to replace these energy resources. To enhance the lifetime of network, energy efficiency is the main design issue to be handled carefully. Most energy dissipation occurs during communication, thus routing protocols in Wireless Sensor Networks mainly focus and strive to minimize the energy utilization. A number of protocols have been developed for Hierarchical Networks Routing aimed at minimizing the energy utilization and at prolonging the network life. However, there still is a need for enhanced protocols to further improve the lifetime of the network. To that end, a new technique called Shortest Path Tree Scaling Hierarchical Power Efficient Routing (SPTSHPER) for WSN is proposed in this work. In the SPTSHPER, the network operations are divided into two phases. These phases are zone setup phase and data communication phase. In zone setup phase, first network is divided into sub zones called clusters, and a node is selected as a representative node called Cluster Head (CH). In data communication phase, the actual transmission of data between nodes to Cluster Head and Cluster Head to the Base Station (BS) occurs. Dijkstra?s Algorithm is used to find the Shortest Path Trees (SPT) rooted at Base Station to all other cluster heads. In this way, sensor data is transmitted to Base Station by Shortest Path Tree. To prolong the lifetime of the network and to save average energy the SPTSHPER evenly distributes the energy dissipation among all the sensor nodes. The novelty of the proposed protocol lies in the use of both single-hop and multi-hop routing. In multi-hop routing it uses the Shortest Path Trees to communicate with the BS. The significant advantage of the proposed approach is that the network scalability is preserved by using both single-hop and multi-hop routing. Moreover, by using Dijkstra?s Algorithm the SPTSHPER can save energy and reduce delay of the data package among Cluster Heads and Base Station.
