Data acquisition from a multi‐hop large‐ scale outdoor wireless sensor network (WSN) deploy‐ ment for environmental monitoring is full of chal‐ lenges. This is because the severe resource constraints on small battery‐operated motes (e.g., bandwidth, memory, power, and computing capacity), the big data acquisition volume from the large‐scale WSN, and the highly dynamic wireless link c...

Introduction In this paper we consider cell centered nite di erence approximations for second order convection di usion equations of divergence type Our goal is to construct nite di erence methods of second order of approximation that satisfy the discrete maximum principle The error estimates are in the discrete Sobolev spaces associated with the considered boundary value problem Approximation ...

A rabbit lymphocyte-mouse myeloma hybrodoma (RX54-3) was administered to BALB/c mice, in order to determine whether hybridoma cells have any protective effect on the tumorigenicity of the P3X63/Ag8 mouse myeloma cell line, one of the parents of this hybridoma. Two sublines of RX54-3 were studied, (a) "new" cells, which produce rabbit light chains and mouse immunoglobulin, are killed by anti-mye...

Bacteria or their products have repeatedly been reported to have a beneficial effect on human neo plastic disease (@l, 7, 192).The earlier work has been reviewed by Shear (8), Shwartzman (9), and Andervont (1). Since then, many additional ob servations on tumor inhibition or regression asso ciated with naturally occurring or artificially in duced infections have been reported (4). Despite the e...

Today’s cellular technologies allow users to access the Internet in a car or on a high-speed train, albeit the access bandwidth is far lower than that through a typical wired access technology such as Ethernet. Numerous new applications and services are under development for users of wireless technologies. Locationbased services (e.g, GPS navigation) and streaming media services are just two ex...

background: in recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. objectives: this study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing chal lambs. methods: eighteen male ...

background: caprine besnoitiosis is an economically important disease of goats. neospora caninum, another coccidian parasite of worldwide distribution, infects several animal species and is a major cause of abortion in cattle . combined infections of n. caninum and besnoitia caprae can occur in geo-graphical areas endemic for both species of parasite in goats. this experiment was conducted to i...

ever-increasing advances in the field of bioethics have been encouraged by recent developments of biomedical technolo-gies. stem cell research and therapy are among the most promising approaches in medicine of which are raised some ethical chal¬lenges. likewise, the therapeutic potential of stem cell-based therapies created new policy concerns for health care sys¬tems, particularly the issue of...

Nowadays, in a competitive and dynamic environment of businesses, organizations need to moni-tor, analyze and improve business processes with the use of Business Process Management Systems(BPMSs). Management, prediction and time control of events in BPMS is one of the major chal-lenges of this area of research that has attracted lots of researchers. In this paper, we present a...

Bitcoin and blockchain technologies have proven to be a phenomenal success. Œe un-derlying techniques hold huge promise to change the future of €nancial transactions, andeventually the way people and companies compute, collaborate, and interact. At the sametime, the current Bitcoin-like proof-of-work based blockchain systems are facing many chal-lenges. For example, a huge amoun...
