Wireless sensor network (WSN) technologies are considered one of the key research areas in computer science and the healthcare application industries for improving the quality of life. The purpose of this paper is to provide a snapshot of current developments and future direction of research on wearable and implantable body area network systems for continuous monitoring of patients. This paper explains the important role of body sensor networks in medicine to minimize the need for caregivers and help the chronically ill and elderly people live an independent life, besides providing people with quality care. The paper provides several examples of state of the art technology together with the design considerations like unobtrusiveness, scalability, energy efficiency, security and also provides a comprehensive analysis of the various benefits and drawbacks of these systems. Although offering significant benefits, the field of wearable and implantable body sensor networks still faces major challenges and open research problems which are investigated and covered, along with some proposed solutions, in this paper.

ABSTRACT:The present study was conducted to evaluate 16 crosses between 4 breeds of rabbits from a physiological point of view. The breeds tested were Baladi Red (BR), Chinchilla Giganta (ChG), French Giant Papillon (FGP) and Simenwar (S). A total number of 6144 blood samples were collected to detect the effect of crossing, age of kits, month of kindling and sex effects. The traits evaluated were: haematological parameters; red blood cell count (RBCs), haemoglobin concentration (Hb), haematocrit value (Ht%), biochemical parameters of plasma; total protein (TP), albumin (Alb), globulin concentration (Glo), albumin/globulin ratio (Alb/Glo) and triglycerides (TG). BR or its crosses, using BR sires or BR dams, showed the highest value of RBCs, Hb and Ht%. Crossbred rabbits obtained from mating BR and FGP rabbits had the highest Glo values. Rabbits which were born in May-June months had the highest values of TP and its fractions (Alb and Glo). Age of kits had a highly signifi cant effect (P<0.001) on RBCs, Hb, Ht%, TP and TG. Moreover, Glo and Alb/Glo ratio (P<0.01) and Alb (P<0.05) were also signifi cantly affected. Sex had no signifi cant effect on all studied parameters. Signifi cant positive correlations were found between TP and each fi nal body weight, total weight gain, total feed intake, carcass weight and dressing percentage, while signifi cant negative correlation was found with feed conversion.

In lase years with all of the attention paid to social networks (SN) and Web 2.0 tools these days, it is important to both explore their uses and evaluate their effectiveness in supporting communication, developing, and revolutions of countries, are rapidly evolving technology and play an important role in every daily life activities in societies. This technology includes wikis(Wikipedia, Seedwiki), blog, micro blogging (Twitter), YouTube, social book marking, podcasts, Second Life (virtual communities), and RSS.This paper will illustrate how Web 2.0 technology has been successfully used as a supplement for communicative practice in societies. Moreover, this paper explores the impact of communication SNs, Web 2.0 technologies, and the Internet in particular, has been widely credited as contributor to the democracy and freedom of countries. Some challenges of SNs and Web 2.0 have been overviewed. In addition to, the role of such technologies has been influenced by the Tunisian and Egyptian revolutions in 2011 which have been explained and highlighted in this work.
