Over the past three decades, dengue fever/dengue hemorrhagic fever has been rapidly expanding in the Eastern Mediterranean Region with outbreaks documented in countries along the coastal lines of the Red Sea and Arabian Sea and in Pakistan. The paper describes the current situation in the Region and proposes specific areas for strengthening of core capacities in the short, medium and long term ...

monitoring of water levels within the seas and oceans has been enhanced by application of satellite radar altimetry missions, compared to the traditional in-situ tide gauge measurements, due to their vast coverage and better spatial resolution. satellite radar altimetry, which is originally designed to measure global ocean surface height, has been applied to inland surface water hydrologic stud...

Two new triterpene glycosides, scabraside A (1) and B (2), and a structurally known compound (3), were isolated from the sea cucumber Holothuria scabra (Holothuriidae) collected from the South China Sea. Structure of these compounds was elucidated by spectroscopic and chemical methods. The glycosides 1 and 2 exhibit the same common structural features, i. e., the presence of 12- and 17-hydroxy ...

Activity-guided isolation of the fermentation broth of the deep-sea derived fungus Acaromyces ingoldii FS121, which was obtained from the China South Sea, yielded a new naphtha-[2,3-b]pyrandione analogue, acaromycin A (1) and a new thiazole analogue, acaromyester A (2), as well as the known compound (+)-cryptosporin (3). Their structures, including absolute configurations, were determined by ex...

in this paper, we consider a cooperative cognitive radio network in which there is an ofdm primary link and multiple single carrier secondary links.the primary link is required to maintain its secrecy rate above a predefined threshold. if the secrecy rate requirement is not satisfied, the secondary system help primary link to maintain its secrecy rate requirement. in doing so, the secondary trans...

800x600 in order to determine the effect of intracorneal rings (intacs sk), when implanted in keratoconic patients, on corneal curvature, uncorrected visual acuity (ucva), best corrected visual acuity (bcva) and on the progression of the cone through three years follow-up period. in this prospective nonrandomized study 114 eyes of 71 keratoconic patients (38 females and 33 males) were implanted...

Recently, the fifth-generation (5G) of wireless networks mainly focuses on terrestrial applications. However, well-developed emerging technologies in 5G are hardly applied to maritime communications, resulting from lack communication infrastructure deployed vast ocean, as well different characteristics propagation environment over sea and user distribution. To satisfy expected plethora broadban...

This article presents a simulated and experimental analysis of the effects evaporation duct on microwave propagation in Irish Sea. The is phenomenon that occurs almost permanently over all world’s oceans allows electromagnetic waves to travel beyond horizon. Weather data logged several years from four buoys off east coast Ireland has been analyzed find probability strength duct. Signal using pa...

The Medical Device Coordination Framework (MDCF) is an open source middleware package for interoperable medical devices, designed to support the emerging Integrated Clinical Environment (ICE) interoperability standard. As in any open system, medical devices connected to the MDCF or other ICE-like network should be authenticated to defend the system against malicious, dangerous, or otherwise una...
