In this paper, we have investigated some of the most recent energy efficient routing protocols for wireless body area networks. This technology has seen advancements in recent times where wireless sensors are injected in the human body to sense and measure body parameters like temperature, heartbeat and glucose level. These tiny wireless sensors gather body data information and send it over a wireless network to the base station. The data measurements are examined by the doctor or physician and the suitable cure is suggested. The whole communication is done through routing protocols in a network environment. Routing protocol consumes energy while helping non-stop communication in a wireless environment. Because of the very tiny size, energy consumption matters a lot. We have focused on the protocols, which provide energy efficiency and improve network lifetime, through put and minimal path loss. We will be discussing some of the most recent energy efficient routing protocols in this paper; later their comparison with an appropriate table is presented. In addition, recent challenges, possible application and perspectives are discussed.

They also took from the less disciplined narrators, but they chose from their conversations a selection, and for this some prominent narrators who can be considered that Ibn Habban has been hardened to weaken them. Narrators who avoided Ibn Habban novel They are not true because Ibn Habban neglected her and left her to hurt some narrators who are confident in themselves
The Ayyub era witnessed a popular for science, knowledge and became the Ayyub state in its various regions a scientific beacon، despite their preoccupation with wars with the Crusaders now that did not discourage them from their care for science and scientists، and this scientific renaissance had many factors، foremost of which are the tendencies of the sultans and Ayyub kings to pay attention to science and its care، through their establishment of the role of science

... Show MoreBackground: preparation of root canals is an important step in root canal treatment. Mechanical instrumentation of root canals cause an irregular layer of debris, known as the smear layer. As a result, several studies reported that preferring the removal of the smear layer. Objective: To study the influence of the energy (100 mJ) of Erbium, Chromium: Yttrium Scandium Gallium Garnet (Er,Cr:YSGG) laser at short pulse duration (60 μs) on smear layer removal of apical third after using Photon induced photoacoustic streaming technique. Materials and methods: Eighteen straight single-rooted mandibular premolars were used. The roots length were uniform to 14mm from the anatomic apex and
