Full Text Available Copepod community along the Mediterranean Moroccan coast was investigated, for the first time, during April 2013. Total abundance varied from 53 to 4557 ind. m-3 and high values were found in coastal waters. Oithona nana and Paracalanus parvus dominated in the entire area and species diversity was decreasing from the West to the East. Hierarchical clustering revealed three groups of stations, depending on their geographic position (western, central and eastern areas. Indicator species analysis pointed out that Clausocalanus furcatus and Gaetanus sp. were significantly associated with Group I, Clausocalanus sp., Centropages sp. and Centropages chierchiae with Group II, whereas Temora longicornis was significantly associated with Group III. Detrended Correspondence Analysis based on the species abundance and environmental variables (temperature, salinity, chlorophyll-a, highlighted a more or less similar setting of stations which was related to salinity and temperature. The presence of three anticyclonic gyres at the northern part of the study area is suggested as the major factor acting on the variability of copepod community along the Mediterranean Moroccan coast.

Seven microsatellite markers were used to study genetic diversity of three Egyptian (Egyptian Baladi, Barki and Zaraibi) and two Italian (Maltese and Montefalcone) goat breeds. The microsatellites showed a high polymorphic information content (PIC) of more than 0.5 in most of the locus-breed combinations and indicated that the loci were useful in assessing within- and between-breed variability of domestic goat (Capra hircus). The expected heterozygosity of the breeds varied from 0.670 to 0.792. In the geographically wider distributed Egyptian Baladi breed there were indications for deviations from random breeding. Analysis of genetic distances and population structure grouped the three Egyptian goat breeds together, and separated them from the two Italian breeds. The studied Mediterranean breeds sampled from African and European populations seem to have differentiated from each other with only little genetic exchange between the geographically isolated populations.

In this paper we present the concentrations of Hg, Cd, Se, Pb, Cu, Mn, Zn and Fe in organs of 6 non-common specimens of cetaceans that were stranded along the Israeli Mediterranean coast (IMC), during 2002-2010: two fin whales, one minke whale, one Cuvier's beaked whale, one rough-toothed dolphin, and one Risso's dolphin. Most of the specimens were calves stranded by accident. Concentrations of Hg and Cd were low in tissues of the baleen whales and higher in the toothed whales, with maximum concentrations of 1067 mg kg(-1) Hg in the liver of the Risso's dolphin and 29 mg kg(-1) Cd in the kidney of the Cuvier's beaked whale. As far as we are aware, this is the first report of trace elements in baleen whales in the Eastern Mediterranean, and the first report of trace elements in minke whale and rough-toothed dolphin in the Mediterranean.

A review of wave climate and prediction along the Spanish Mediterranean coast

Directory of Open Access Journals (Sweden)

A. Sánchez-Arcilla

2008-11-01

Full Text Available This paper reviews the characterization of wave storms along the Spanish/Catalan Mediterranean coast. It considers the "physical" and "statistical" description of wave parameters and how they are affected by the prevailing meteo patterns and the sharp gradients in orography and bathymetry. The available field data and numerically simulated wave fields are discussed from this perspective. The resulting limits in accuracy and predictability are illustrated with specific examples. This allows deriving some conclusions for both short-term operational predictions and a long-term climatic assessment.

2004-01-01

Within the framework of the Water Management Master-plan, a bio-indicator network (RINBIO) was deployed all along the French Mediterranean coast (1,800 km), using man-made cages containing mussels (Mytilus galloprovincialis) to assess contamination by heavy metals, persistent organic products and radionuclides. The caging technique compensated for the scarcity of natural shellfish stocks in significant parts of the coast and enable comparison between sites regardless of their physicochemical and trophic characteristics. Among the 103 stations of the entire program, 40 were selected for the measurement of anthropogenic radionuclides by high-efficiency gamma-spectrometry. Biometrics parameters of the each mussel samples, including 'condition index' as an indicator of soft part growth, will be correlated with radionuclides activities, allowing to correct raw data from differences in bioaccumulation between the various sites in relation to their trophic levels. A comprehensive picture of the distribution of radionuclides at a such a large spatial scale will be provided and the contribution of the Rhone river input, so far the main source for the coastal zone, will be investigated.

2018-03-01

Full Text Available This paper provides important information about the compositions and concentrations of polycyclic aromatic hydrocarbons in Alexandria’s coastal seawater during winter of 2015. By applying gas chromatographic technique using the FID detector, the determination of PAHs in seawater was used as a chemical signature to recognize various sources of PAHs pollutions. Concentrations were found to range between 13.4 and 6076 ng/L with a mean 991 ng/L; that exceeded the maximum admissible concentrations (200 ng/L for the water standard of the European Union. Percentage distribution of water samples showed that 41.7% of the analyzed samples contained less than 500 ng/L and 4.2% exhibited high concentrations that exceeded 6000 ng/L. The PAHs of four, five and six rings were 84%, 16.7%, 5.5% of the total PAH, respectively; while low molecular-weight did not exceed 1.5%. The sources of PAHs in the investigated area were mainly from pyrolytic origin that had been derived from incomplete combustion of the fuel of boats and vehicle engines with little evidence of petrogenic origins in El-Mex and Abou-Qir bay. Contribution of PAHs from El-Mex Bay and Eastern Harbor was found to be 2,860 and 15.3 kg/year, respectively. Keywords: PAHs, Pollution, GC-FID, Seawater, Egyptian Mediterranean

Egyptian imprints on Geto-Dacian magical medicine.

Baran, Dana

Several characteristics of Egyptian culture and civilization could be identified in prehistoric and ancient historic Geto-Dacian territories, belonging to modern Romania (Fig. 1). From early times, magic, religion and philosophy have been part of pre-scientific medicine. Therefore these aspects are to be tackled when speaking of medicine in mythological or legendary ages. Progress of ancient Geto-Dacian medicine was principally ascribed to the interface of local civilizations with ancient Egypt, Greece and Rome. Such connections were well documented and understood in historic times and were mainly based on texts of renowned Greek and Roman historians. Egyptian impact upon Dacia, -the ancient name of today's Romania-, was often explained in terms of indirect Greek- or Roman-mediated influences.The Greek and then the Roman colonies on the Black sea shore, together with later Roman colonies in Dacia Felix, founded in the heart of Transylvania, enabled access for Romania to Mediterranean cultures, including that of Egypt.

Torrential precipitations on the Spanish east coast: The role of the Mediterranean sea surface temperature

Science.gov (United States)

Millán, M.; Estrela, M. J.; Caselles, V.

Floods constitute one of the most important natural risks on the Spanish Mediterranean coast. Although it is very difficult to avoid them, a correct understanding of their principal cause, which is torrential rain, can facilitate their prediction and in this way avoid, at least partially, their catastrophic effects (both loss of human lives and material damage). The work presented here is part of a more extensive study underway in the CEAM (Centro de Estudios Ambientales del Mediterráneo). Its objective is the analysis of the conditions that produce torrential precipitations. These can be explained by the hypothesis of the Back Door Front, a mechanism which on its own permits the development of a potentially unstable mass above the Mediterranean sea. Among the different factors that are valued in this hypothesis, the Sea Surface Temperature is considered to play an important role. It is studied by means of satellite images since this is the only technique that permits a synoptic view of this parameter. NOAH satellite images have been used, applying the split-window operative technique. This work presents initial results that confirm the importance of the Sea Surface Temperature (SST) as a moisture source in the Mediterranean cyclogenesis.

Increasing severity of damage caused by floods in the Spanish Mediterranean coast (1960-2014), climate change or vulnerability?

Science.gov (United States)

Perez, Alfredo; Gil, Salvador; Lopez, Francisco; Barriendos, Mariano

2016-04-01

In recent decades, there has been an increase in physical and economic losses (WMO, CRED and UCL, 2014) that raises serious concerns in society. Climate change projections may explain the rise in flood losses; however, these shouldn't be considered yet (Bouwer, 2011). According to IPCC (2014), there is low confidence in anthropogenic climate change affecting the frequency and magnitude of fluvial floods on a global scale. In other words, this increase in flood events is not completely related to the higher frequency of heavy rainfall. To illustrate the aforementioned, a spatial example can be seen in the study area. In the Spanish Mediterranean coast, we see an increase in economic losses within the last 50 years due to flood events (Gil et al., 2014). It seems that the socio-economic growth and the rise of housing construction (Gaja, 2008) have led to an increase in vulnerability and exposure which are mainly responsible for those losses and the increase in severity of flood events (Pérez et al., 2015). Furthermore, this situation will probably become more precarious if some climate forecasts are met [IPCC, 2014; AEMET, 2015], and if the economic model fails to adopt efficient adaptive measures. Therefore, it is interesting to focus attention on social factors either within the present or future scenario in order to minimise the potential consequences and improve the adaptation. The main objective of this work focuses on the study of the evolution of the severity of the floods in the Spanish Mediterranean coast for the period (1960-2015). To do that, a statistical analysis of the data base [Gil et al., 2014; extended to the entire Spanish Mediterranean coast (MEDIFLOOD)] and a multiscale mapping (local, provincial and regional level) of the frequency of these events will take place in order to make comparisons and show spatiotemporal patterns according to the severity events evolution. Preliminary results show some interesting statistically significant

2012-08-01

Full Text Available Marine organisms are potentially prolific sources of highly bioactive secondary metabolites that might represent useful leads in the development of new pharmaceutical agents. The Moroccan marine biodiversity including macroalgae remains partially unexplored in term of their potential bioactivities. Antibacterial activity of methanolic extracts from 20 species of macroalgae (9 Chlorophyta, 3 Phaeophyta and 8 Rhodophyta collected from Moroccan Mediterranean coasts was evaluated against Escherichia coli, Staphylococcus aureus and Enterococcus faecalis. The extracts of the studied Rhodophyceae inhibited considerably the growth of the three tested bacterial strains and gave inhibition zones between 20 and 24 mm. The results indicate that these species of seaweed present a significant capacity of antibacterial activities, which makes them interesting for screening for natural products.

The French Institute for Radioprotection and Nuclear Safety (IRSN) runs a continuous monitoring program of the marine environment as a mandatory task. For the French Mediterranean coast, this monitoring activity focuses on two bio-indicators species: the Mediterranean mussel (Mytilus galloprovincialis) and the red mullet (Mullus sp.) sampled on a regular basis from natural populations at ten locations along the coast. Radionuclides are measured using direct low-level gamma spectrometry as a routine technique. In addition to this long-lasting monitoring, a broad survey of radionuclide baseline levels is conducted on all compartments of the coastal zone: water, sediments and a large selection of fish species among those most currently fished and marketed. This extended data collection is necessary to fulfill the information requirements of the UE Marine Strategy Framework Directive (MSFD) and its implementation by member states. This information is also essential for impact assessment of any incident or accident, included from a remote source. Levels of less commonly measured radionuclides like {sup 3}H, {sup 14}C, {sup 90}Sr, {sup 210}Po and U, Pu isotopes are investigated. Fish sampling relies mostly on scientific stock assessment campaigns. Mussel sampling is complemented by transplanted mussels on 40 specific sites. This regional survey also focuses on two possibly impacted areas: the Rhone river mouth coastal zone, with inputs from nuclear power plants along the river and the Bay of Toulon sheltering Navy harbor of nuclear-powered sub-marines and aircraft-carrier. First results show that the activity levels of artificial radionuclides are very low for most bio-indicator species, in accordance with previous monitoring trends. {sup 137}Cs is the only artificial radionuclide regularly detected by gamma spectrometry in mussel and fish samples at a level below 1 Bg.kg{sup -1} of dry weight. Values of {sup 3}H (organically bound Tritium) in the same samples lies under

NAA of the 'Minoan pumice' at Thera and comparison to alluvial pumice deposits in the Eastern Mediterranean region

Neutron activation analysis was used to determine up to 30 elements in the pumice layers from the 'Minoan eruption' at Thera (Santorini, Greece). Mt Pilato (Lipari, Italy) and in alluvial pumice from coasts of the Eastern Mediterranean region. The morphologically well distinguishable layers of the 'Minoan pumice' were found to be of nearly similar composition in respect to the elements determined and their distribution patterns could therefore be used to identify a sample as Santorinian or not. Additionally, this method was applied to pumice lumps found during archaeological excavations in the Nile delta, Egypt. The results showed that two of the three Egyptian samples are products of the Minoan eruption at Thera and therefore chronologically useful. A second group of pumices collected at Antalya (Turkey), Crete (Greece) and also in Egypt was found to have a distinctly different composition and is therefore related to another volcanic event.

In this study, the nutritive value of truffles was evaluated as protein efficiency ratio (C-PER) compared with casein C-PER. of white truffle was higher than brown truffle and therefore had a better nutritional quality over the brown truffle. Egyptian truffle could be considered as a good source of protein with good essential amino acids content and high nutritive value. It was found that white and brown truffles (Al-Kamah) grow in the north westarn coast of the Egyptian desert, white truffle was identified as Tirmania nivea while brown truffle was identified as Terfezia boudieri. Rats were fed on normal diet as (basal diet) for two weeks, then they were fed on the same diet with 10% of casein (control diet), replaced by 20% of irradiated and non irradiated white and brown truffle dried samples as a protein source. The nutritive value parameters were measured at the end of the experiment, gains in body weight, daily food intake, feed conversion ratio, protein efficiency ratio were measured, biological value, the biological effect on liver kideny function serum glucose. LDL and HDL-cholesterol were investigated too

Jellyfish blooms cause important ecological and socio-economic problems. Among jellyfish, cubozoans are infamous for their painful, sometimes deadly, stings and are a major public concern in tropical to subtropical areas; however, there is little information about the possible causes of their outbreaks. After a bloom of the cubomedusa Carybdea marsupialis (Carybdeidae) along the coast of Denia (SW Mediterranean, Spain) in 2008 with negative consequences for local tourism, the necessity to understand the ecological restrictions on medusae abundance was evident. Here we use different models (GAM and zero-inflated models) to understand the environmental and human related factors influencing the abundance and distribution of C. marsupialis along the coast of Denia. Selected variables differed among medusae size classes, showing different environmental restriction associated to the developmental stages of the species. Variables implicated with dispersion (e.g. wind and current) affected mostly small and medium size classes. Sea surface temperature, salinity and proxies of primary production (chl a, phosphates, nitrates) were related to the abundances of small and large size classes, highlighting the roles of springtime salinity changes and increased primary production that may promote and maintain high densities of this species. The increased primary (and secondary) production due to anthropogenic impact is implicated as the factor enabling high numbers of C. marsupialis to thrive. Recommendations for monitoring blooms of this species along the study area and applicable to Mediterranean Sea include focus effort in coastal waters where productivity have been enriched by anthropogenic activities.

Saleh, Salah

2016-07-01

The present Tectonic system of Southeastern Mediterranean is driven by the collision of the African and Eurasian plates, the Arabian Eurasian convergence and the displacement of the Anatolian Aegean microplate, which generally represents the characteristic of lithospheric structure of the region. In the scope of this study, Bouguer and the satellite gravity (satellite altimetry) anomalies of southeastern Mediterranean and North Eastern part of Egypt were used for investigating the lithospheric structures. Second order trend analyses were applied firstly to Bouguer and satellite altimetry data for examining the characteristic of the anomaly. Later, the vertical and horizontal derivatives applications were applied to the same data. Generally, the purpose of the applying derivative methods is determining the vertical and horizontal borders of the structure. According to the results of derivatives maps, the study area could mainly divided into important four tectonic subzones depending on basement and Moho depth maps. These subzones are distributed from south to the north as: Nile delta-northern Sinai zone, north Egyptian coastal zone, Levantine basin zone and northern thrusting (Cyprus and its surroundings) zone. These zones are separated from each other by horizontal tectonic boundaries and/or near-vertical faults that display the block-faulting tectonic style of this belt. Finally, the gravity studies were evaluated together with the seismic activity of the region. Consequently, the geodynamical structure of the region is examined with the previous studies done in the region. Thus, the current study indicates that satellite gravity mission data is a valuable source of data in understanding the tectonic boundary behavior of the studied region and that satellite gravity data is an important modern source of data in the geodynamical studies.

Full Text Available Proliferations of the genus Pseudo-nitzschia recur along the Catalan coast (NW Mediterranean throughout the year. The establishment of 58 clonal cultures facilitated morphological studies with scanning electron microscopy (SEM and ITS 5.8S rDNA sequence characterization. Moreover, strains of each species were examined with respect to sexual compatibility and toxicity. The results of the morphological and phylogenetic studies confirmed nine species of the genus Pseudo-nitzschia: P. brasiliana, P. calliantha, P. delicatissima clade A/del 2, P. arenysensis, P. fraudulenta, P. galaxiae, P. linea, P. multistriata and P. pungens clade I. Moreover, two Pseudo-nitzschia species, P. caciantha and P. cf mannii, could only be identified following SEM analysis of their morphology. None of the cultured strains of Pseudo-nitzschia analyzed produced domoic acid in amounts above the limit of detection. The current distributions of the Pseudo-nitzschia species in the Mediterranean Sea were plotted on maps, which led to the following observations: i diversity within this genus is much greater than previously considered, ii some species have a broad distribution (e.g. P. calliantha, iii whereas the distribution of others is narrowly restricted (e.g. P. pungens clade I. Moreover, this study reports the first detection of P. linea in the Mediterranean Sea and is the first description of P. galaxiae and P. cf mannii along the Catalan coast. Morphological studies coupled with molecular biological characterization, mating tests and biogeographic distribution analyses provide a critical theoretical basis for testing and/or implementing the current phylogenetic framework in the genus Pseudo-nitzschia.

The Environmental Monitoring Program for the Egyptian coastal waters of the Mediterranean Sea was established to initiate a monitoring data base system. This was done by applying quality control assessments to evaluate and protect the coastal zone, which ensure its sustainable use. An environmental risk assessment was performed, including a screening level ecological risk assessment (SLERA) and a human health risk assessment (HHRA). The aim of SLERA risk assessment was to determine which classes of chemical pollutants could possibly cause adverse ecological effects to benthic species and to determine whether hot spots exist or not. Investigation of the sediments revealed that the region which extends from the Alexandria harbor area to Port Said City is enriched with trace metals, polycyclic aromatic hydrocarbons (PAHs) and organo chlorine pesticides. Polychlorinated biphenyls (PCBs) were detected but in lower concentrations compared to the other organic compounds. The spatial distribution of the different contaminants investigated here showed that the Nile Delta region is more influenced by waste water discharge than the rest of the Egyptian coastal regions. In addition to sediments, two mussel species (Mactra corallina and Tapes decussate) were successfully used as bio indicators of marine environmental quality. The concentrations of most pollutants investigated (except organo chlorine pesticides, and some trace metals) were higher in the tissues of the mussels, especially M. caerulein, than in sediments. The highest concentration of PAHs in sediments and mussels were observed in front of the Alexandria harbor and Nile Delta, they possibly affected by shipping activities. Natural radioactivity of surface sediments and sea water samples were measured along the coastal Mediterranean Sea between Alexandria and Port Said City. The main source of radiation along the area is the black sands, which is rich in radionuclides. The measured values of "2"3"8U and "2"3"2Th for

Low crested coastal defence structures on the Catalan coast of the Mediterranean Sea: how they compare with natural rocky shores

2007-06-01

Full Text Available Erosion problems in coastal zones are increasingly threatening Mediterranean shores. In tourist areas such as the Catalan coast, there has been an increasing demand for the construction of low crested structures (LCS to maintain beaches for recreational purposes. We studied the composition of the biota from three LCS and compared it with that of nearby natural rocky shores. Our purpose was to assess the composition of the communities growing on the LCS at a regional scale and to explore potential patterns of community composition in LCS in relation to the nature of the surrounding coast (i.e. sand or rocky shore, distance from natural hard-bottom communities and orientation of the blocks within the structure. The communities growing on the LCS were similar to those from nearby natural shores but the diversity and the number of taxa was always lower. Sixty to 95% of the species present on natural rocky shores grew on LCS, and differences in the number of taxa between the natural and the artificial substrates increased with increasing distances between them. On the Catalan coast, LCS act as impoverished rocky shores that never become natural ‘climax’ communities.

Winter precipitation and cyclones in the Mediterranean region: future climate scenarios in a regional simulation

Directory of Open Access Journals (Sweden)

P. Lionello

2007-11-01

Full Text Available Future climate projections show higher/lower winter (Dec-Jan-Feb precipitation in the northern/southern Mediterranean region than in present climate conditions. This paper analyzes the results of regional model simulations of the A2 and B2 scenarios, which confirm this opposite precipitation change and link it to the change of cyclone activity. The increase of the winter cyclone activity in future climate scenarios over western Europe is responsible for the larger precipitation at the northern coast of the basin, though the bulk of the change is located outside the Mediterranean region. The reduction of cyclone activity inside the Mediterranean region in future scenarios is responsible for the lower precipitation at the southern and eastern Mediterranean coast.

The ingestion of microplastics and natural fibres (microplastics and natural fibres. A latitudinal increase in condition index (Fulton's K) of S. pilchardus gave an indication that larger individuals with better physical condition are less likely to ingest microplastics and natural fibres. Fibres were the most frequent particle type (83%) and Fourier Transform Infrared spectroscopy (FT-IR) analysis indicated polyethylene terephthalate was the most common microplastics material (30%). Results from this study show that both microplastics and natural fibres of anthropogenic origin are common throughout the pelagic environment along the Spanish Mediterranean coast.

The Mediterranean coast of the Iberian Peninsula concentrates an important part of the population and economic activities in Spain. Intensive agriculture, industry in the major urban centers, trade and tourism make this region the main center of economic dynamism and one of the highest rates of population and economic growth of southern Europe. This process accelerated after Franco regime started to be more open to the outside in the early sixties of the last century. The main responsible factor for this process is the climate because of warmer temperatures and a large number of sunny days, which has become in the economic slogan of the area. However, this growth process has happened without proper planning to reduce the impact of other climatic feature of the area, floods. Floods are the natural hazard that generates greater impacts in the area.One of the factors that facilitate the lack of strategic planning is the absence of a correct chronology of flood episodes. In this situation, land use plans, are based on inadequate chronologies that do not report the real risk of the population of this area. To reduce this deficit and contribute to a more efficient zoning of the Mediterranean coast according to their floods risk, we have prepared a high-resolution floods database (MEDIFLOOD) for all the municipalities of the Spanish Mediterranean coast since 1960 until 2013. The methodology consists on exploring the newspaper archives of all newspapers with a presence in the area. The searches have been made by typing the name of each of the 180 municipalities of the Spanish coast followed by 5 key terms. Each identified flood has been classified by dates and according to their level of intensity and type of damage. Additionally, we have consulted the specific bibliography to rule out any data gaps. The results are surprising and worrying. We have identified more than 3,600 cases where a municipality has been affected by floods. These cases are grouped into more than 700

Full Text Available During summer, when oligotrophic conditions prevail offshore in the Mediterranean Sea, enhanced phytoplankton stripes are often observed in nearshore waters. In this study, we examine the cross-shore hydrographic variability and the associated microbial plankton communities in this zone. Detailed cross-shore underway sampling at 47 coastal sites spread along the Balearic and Catalan coasts revealed the widespread existence of narrow bands of warm and decreased salinity water beholding high phytoplankton biomass (up to 50-fold vs. offshore chlorophyll. Most intense physical and biological anomalies along these transects were generally constrained to the first hundred meters from the shoreline (i.e., a transition zone starting at ~400 m. We use Principal Component Analysis (PCA and k-means cluster analysis to categorize temperature, salinity and chlorophyll (T, S and Chl in three main types of cross-shore trends. Prevalence of exponential-shaped Chl trends was observed particularly in areas with shoreward directed winds (B1-type. The other two trends (B2 and B3 presented variations off the coast produced by alongshore structures like river plumes, city outfalls and other features. Exponential-shaped cross-shore chlorophyll distribution (B1-type accumulated 90% of the total transect Chl variation in the first 367 ± 190 m from the shoreline, whereas this distance was variable in the other profile types. Repeated daily sampling at one site with this transect typology revealed that wind forcing variations produced fast response on cross-shore T and S properties. Chl was less sensitive to changes at this time-scale. Phytoplankton communities exhibited site-dependent responses to the nearshore environment. Pico- and nanoplankton assemblages, typically dominating coastal assemblages during summer in the Mediterranean Sea, showed lower cross-shore variation. Conversely, larger response to nearshore conditions was observed in microplankton populations

Egyptian Mythological Manuals

DEFF Research Database (Denmark)

Jørgensen, Jens Kristoffer Blach

From the hands of Greek mythographers a great number of myths have survived along with philosophical discussions of their meaning and relevance for the Greeks. It is little known that something similar existed in ancient Egypt where temple libraries and archives held scholarly literature used...... by the native priesthood, much of which has only been published in recent years. As part of this corpus of texts, the ancient Egyptian mythological manuals offer a unique perspective on how the Egyptian priesthood structured and interpreted Egyptian myths. The thesis looks at the different interpretative...... techniques used in the Tebtunis Mythological Manual (Second century CE) and the Mythological Manual of the Delta (Sixth century BCE) and the place of these manuals within the larger corpus of priestly scholarly literature from ancient Egypt. To organize the wealth of local myths the manuals use model...

Presented are the research objectives of the project "Irep en Kemet", Wine of Ancient Egypt, and the content of the project's website. This research aims at documenting the complete corpus of wine in ancient Egypt and analysing the data (iconography, textual sources and artefacts) to unveil the importance of the ancient Egyptian wine culture legacy in the Mediterranean region. At this stage, a bibliographical researchable database relevant to wine, viticulture and winemaking in the ancient Egypt has been completed, with 197 entries including articles, books, chapters in book, academic thesis (PhD and MA), essay, abstracts, on-line articles and websites. Moreover, a scene-detail database for the viticulture and winemaking scenes in the Egyptian private tombs has been recorded with 97 entries, some of them unpublished, and the collected data is under study. The titles of the tombs' owners and the texts related to the scenes will be also recorded. A photographic survey of the graves containing images related with viticulture and winemaking will be carried out in order to have the most accurate information on the location and stage of conservation of those images. Our main goal is to provide scholars with a complete, comprehensive archaeological and bibliographical database for the scenes of viticulture and winemaking depicted in the Egyptian private tombs throughout the ancient Egyptian history. The project's website (http://www.wineofancientegypt.com) will include all the collected data, the study and analysis, the project's history and team members, publications as well as the results of our research.

The objective of the present study was to evaluate the influence of pollen of Mediterranean Cypress (Cupressus sempervirens) on the effectiveness of the spa and health resort-based treatment (SHRT) of the patients with broncho-pulmonary pathology at the southern coast of the Crimea (SCC). This article presents the results of the analysis of the data on 122 patients presenting with broncho-pulmonary pathology who received SHRT under the conditions of the Southern Coast of the Crimea. Fifty one (41.8%) of these patients suffered from chronic obstructive pulmonary disease and 71 (58.2%) ones had bronchial asthma. The whole group was comprised of 44 men (36.1%) and 78 women (63.9%). The average (median) age of the patients was 55.8 years. All the participants of the study underwent the comprehensive examination including the general medical and physical examination, complete blood count, the study of sputum cytology and immunological properties of blood including the standard characteristics, IgE and lysozyme levels), evaluation of the respiratory and locomotor (physical) functions with the use of the 6-minute walking test. The aeropollenological study of the aerial environment of the southern coast of the Crimea in the region of Yalta showed that the «bloom» of the Mediterranean Cypress occurs during the period from February till April inclusive. The highest concentrations of cypress pollen are observed in March and early April. The overall effectiveness of SHRT for the patients with broncho-pulmonary pathology arriving for the treatment at the southern coast of the Crimea from other Crimean localities does not depend on the period of «flowering» (the presence of pollen in the air) of the Mediterranean Cypress. In these patients, the termination of the spa and health resort-based treatment during the «flowering» of the Mediterranean Cypress resulted in nothing more than a strained adaptive response manifested as the altered blood leukocyte count.

2015-11-01

The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

2003-07-01

Full Text Available We compared the seabird communities at two sites of the southern and northern shores of the Alborán Sea in the Western Mediterranean (Melilla and Adra respectively during a whole year. Similarities and differences in environmental characteristics of the two study sites were caused by a set of geographical, physical and socio-economic human factors. Sampling was performed weekly during two-hour periods by counting seabirds crossing a given point of the coast. We found similarities in the composition and seasonality of the species between Melilla and Adra. However, there were differences between the two sites in the number of species and individuals, which were usually higher on the southern shore. In this area, seabirds depending on marine trophic resources were more abundant, whereas on the northern shore the most abundant seabird species were those whose feeding habits were not so dependent on sea resources.

The Egyptian swift Rock Pigeon is a breed of fancy pigeon developed over many years of selective breeding. In this work, we report the complete mitochondrial genome sequence of Egyptian swift Rock Pigeon. The total length of the mitogenome was 17,239 bp and its overall base composition was estimated to be 30.2% for A, 24.0% for T, 31.9% for C and 13.9% for G, indicating an A-T (54.2%)-rich feature in the mitogenome. It contained the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region (D-loop region). The complete mitochondrial genome sequence of Egyptian swift Rock Pigeon would serve as an important data set of the germplasm resources for further study.

2016-10-01

Two rare species of parasitic copepods belonging to the genus Lernanthropus de Blainville, 1822 (Siphonostomatoida: Lernanthropidae) are redescribed in detail, based on material collected from Red Sea fishes, caught at El-Tor, near Sharm El-Sheikh on the Red Sea coast of Egypt. Adult females of Lernanthropus sanguineus Song & Chen, 1976 were found on the gills of snapper Lutjanus fulviflamma (Forsskål). This species was known only from its original description based on material from Chinese waters. Adult females of Lernanthropus triangularis Pillai, 1963 were obtained from the gills of mojarra Gerres oyena (Forsskål). Both parasite species are new records for Egyptian Red Sea waters and both host records are new.

Theoretical investigation and mathematical modelling of a wind energy system case study for Mediterranean and Red Sea

Energy Technology Data Exchange (ETDEWEB)

Shata, Ahmed Shata Ahmed

2008-06-26

Fossil fuel is getting more and more expensive every year, and is not readily available in some remote locations. Today, wind power can be harnessed to provide some or all of the power for many useful tasks such as generating electricity, pumping water and heating a house or barn. Egypt has two coastal areas that show significant promise for wind energy exploitation; the north coast on the Mediterranean Sea and the east coast on the Red Sea. The wind energy is utilized along the coast of Mediterranean Sea in Egypt on few occasions, while from national programs for wind energy utilization in Egypt, at the Red Sea coast, the master plan calls for 600 MW which are expected to be achieved by the year 2005. The contribution of fossil fuels (oil and natural gas) to electricity production in Egypt accounts for about 79% of total production, while 21% is hydropower. The demand is expected to grow rapidly to meet the large requirements of future projects. Studies showed that there is an additional need of annual electricity generation capacity around 1000 MW/year up to 2017 [14]. The purpose of this thesis is to present a new analytical method for the calculation of the wind energy potential available along the north coast of the Mediterranean Sea and the east coast of Red Sea in Egypt and moreover, it estimates the possible electrical power generated by large wind turbines and the expected cost in Euro cent/kWh for the power level of 2000 kW. It is hoped that the data analysis will help to identify good sites in Egypt for new wind turbine installations. This evaluation is hoped to trigger the use of large wind turbines at the selected sites along the coasts of Mediterranean Sea and Red Sea in Egypt. (orig.)

Long-term trajectory of some elasmobranch species off the Tuscany coasts (NW Mediterranean from 50 years of catch data

Directory of Open Access Journals (Sweden)

Alessandro Ligas

2013-03-01

Full Text Available The time series of elasmobranch catch rates off the Tuscany coasts (NW Mediterranean were investigated by means of min/max auto-correlation factor analysis in order to estimate variations in population abundance and evaluate the influence of environmental and anthropogenic factors. The analyses highlighted a general decreasing trend in the catch rates of sharks and skates from 1961 to the mid-1990s, mainly influenced by the increase in fishing effort. Since the 1990s, the EU Common Fishery Policy for the Mediterranean has promoted the reduction of fishing fleets through incentives to vessel demolition. The Porto S. Stefano trawl fleet has decreased by about 50%, leading to a decrease in fishing effort which seemed to be the most relevant factor affecting the increasing trend shown by the catch rates of Galeus melastomus, Scyliorhinus canicula and skates from 1991 to 2009. The elasmobranch assemblage did not undergo major shifts but the weighted frequency of occurrence shows that elasmobranchs were more frequent in the past. Particular caution should be paid in interpreting the recent rebound of some species as an early sign of recovery: trawl survey data and landing data show that over the last 50 years elasmobranch fauna have undergone a drastic decline and that recent rebounds are still far from a recovery to historical levels.

Daniel Golani

2006-12-01

Full Text Available The Indian scad, Decapterus russelli, is recorded for the first time from the Mediterranean. The presence of this Indo-Pacific species on the Mediterranean coast of Israel is evidently due to migration from the Red Sea via the Suez Canal. The collection of six specimens in the Mediterranean suggests that this species is well established in the Levant.

Beach impacts of shore-parallel breakwaters backing offshore submerged ridges, Western Mediterranean Coast of Egypt.

Iskander, Moheb M; Frihy, Omran E; El Ansary, Ahmed E; El Mooty, Mohamed M Abd; Nagy, Hossam M

2007-12-01

Seven breakwaters were constructed behind offshore submerged ridges to create a safe area for swimming and recreational activities west of Alexandria on the Mediterranean coast of Egypt. Morphodynamic evaluation was based on the modified Perlin and Dean numerical model (ImSedTran-2D) combined with successive shoreline and beach profile surveys conducted periodically between April 2001 and May 2005. Results reveal insignificant morphologic changes behind the detached breakwaters with slight coastline changes at the down and up-drift beaches of the examined breakwaters (+/-10 m). These changes are associated with salient accretion (20-7 0m) in the low-energy leeside of such structures. Concurrent with this sand accretion is the accumulation of a large amount of benthic algae (Sargassum) in the coastal water of the shadow area of these structures, which in turn have adverse effects on swimmers. Practical measures proposed in this study have successfully helped in mitigating such accumulation of algae in the recreation leeside of the breakwaters. The accumulation of Sargassum, together with the virtual insignificant changes in the up-drift and down-drifts of these structures, is a direct response to both coastal processes and the submerged carbonate ridges. Coastal processes encompass reversal of the directions of long-shore sand transport versus shoreline orientation, the small littoral drift rate and sand deficiency of the littoral zone. The beach response to the breakwaters together with the submerged ridges has also been confirmed by applying the ImSedTran-2D model. Results indicate that submerged ridges play a principal role in the evolution of beach morphology along the west coast of Alexandria. Although the study area is exposed to more than 70% wave exposures, the morphodynamic behavior of the beaches indicates that the submerged ridges act in a similar way as an additional natural barrier together with the artificial detached structures.

Biodiversity and biogeographic relationships of the polychaete fauna in French Atlantic and Mediterranean waters

Directory of Open Access Journals (Sweden)

Jean-Claude Dauvin

2006-12-01

Full Text Available A survey of the literature, including the recent systematic reviews, reveals that 934 polychaete species have been recorded in French Atlantic (including the English Channel and Mediterranean marine waters, including 818 species living on the continental shelf and 116 species that are strictly bathyal. These 934 species belong to 71 families, among which the Syllidae is the most diverse (97 species, followed by the Serpulidae (69 species, Spionidae and Phyllodocidae, each with more than 40 species. Forty-four families have fewer than 10 species recorded in each. The total number of species is spread over 11 continental shelf areas as well as the Atlantic and Mediterranean bathyal depths. In terms of species diversity, the richest areas are the Mediterranean coasts of Provence-Côte d’Azur (507 species and Languedoc-Roussillon (483 species, the western part of the English Channel (402 species, and the southern part of the Bay of Biscay (343 species. The lowest numbers of species were recorded in the eastern English Channel, due to an impoverishment of all the fauna in this part of the Channel. Other areas—for example, the Iroise Sea, the coast of Corsica and Mediterranean bathyal depths—also show low numbers, but this may only reflect the fact that insufficient information about these areas is available. A similarity analysis of 13 areas distinguishes four distinct faunal groups, each specific to one of four general locations: (1 the bathyal Atlantic and Mediterranean zones, including the coast of Corsica, (2 the two Mediterranean coastal areas (Provence-Côte d’Azur and Languedoc-Roussillon, (3 the four zones of the Atlantic continental shelf, and (4 the English Channel. The combined species can be separated into 17 different biogeographic groups.

Díaz-Martínez, J. Vicente; Segura, Sara; Estellés, Víctor; Utrillas, M. Pilar; Martínez-Lozano, J. Antonio

2013-04-01

statistics from MODIS with corresponding temporal statistics from AERONET, as proposed by Ichoku et al. (2002). Eight Mediterranean coastal sites (in Spain, France, Italy, Crete, Turkey and Israel) with available AERONET and MODIS data have been used. These stations have been selected following QA criteria (minimum 1000 days of level 2.0 data) and a maximum distance of 8 km from the coast line. Results of the validation over each site show analogous behaviour, giving similar results regarding to the accuracy of the algorithms. Greatest differences are found for the AOD obtained over land, especially for drier regions, where the surface tends to be brighter. In general, the MODIS AOD has better a agreement with AERONET retrievals for the ocean algorithm than the land algorithm when validated over coastal sites, and the agreement is within the expected uncertainty estimated for MODIS data.

1994-01-01

A permanent stations has been established in the Eastern Mediterranean coast of Turkey for continuous monitoring of aerosols and precipitation. The station is part of the MED-POL programme which includes all countries that have coasts in the Mediterranean Sea and attempts to determine the role of the atmospheric fluxes of pollutants on the pollution of the Mediterranea Sea. Aerosol and deposition samples have been collected since early 1992. Concentrations of SO 4 , NO 3 , Cl, Li, Pb, K, Ca, Al, As, Cd, Cr, Cu, Se, Zn and Na were determined by ion chromatography and atomic absorption spectrometry. Daily samples will be screened to select the ones which correspond to transport from Europe and will be analyzed for a larger number of parameters using INAA. Method development took most of the time in 1992, and analysis are still in progress. Available data have shown that concentrations of anthropogenic elements are smaller in the Eastern Mediterranean atmosphere compared to other rural sites in the Europe.

Full Text Available Hitherto a single species of Doridicola Leydig (Poecilostomatoida: Rhynchomolgidae has been found reported in association with gorgonians in Europe: Doridicola botulosus (Stock and Kleeton, 1963, living on the Mediterranean gorgonian Eunicella singularis (Esper, 1791. During a survey along the Iberian Mediterranean coast, several specimens of D. botulosus were collected from its reported host. Furthermore, an undescribed species of Doridicola was discovered living in association with Paramuricea clavata (Risso, 1826, a Mediterranean gorgonian usually living in overlaps with that of E. singularis. Although the new species is close to D. botulosus, they differ in the oral appendages. A common origin of these two species was suggested. This is a good example of sibling species produced by the colonisation of two hosts with overlapping habitats

NAA was employed to determine the concentration of 27 elements in an Egyptian cigarette filter before and after smoking. The filter of three foreign cigarette brands were also analyzed and compared to the Egyptian brand. The elements determined are Al, As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Mg, Mn, Na, Ni, Rb, Sb, Sc, Se, Sr, Th, Ti, V and Zn. It was observed that the concentration of the measured elements in the Egyptian brand were within the concentration range of foreign brands, and that the concentration of As, Br, Cl, K, Na and Se in the filters increased after smoking regardless the brands examined.

Seagrass as major source of transparent exopolymer particles in the oligotrophic Mediterranean coast

KAUST Repository

Iuculano, Francesca

2017-01-09

The role of seagrass, Posidonia oceanica, meadows as a source of transparent exopolymer particles (TEP) to Mediterranean coastal waters was tested by comparing the TEP dynamics in two adjacent coastal waters in the oligotrophic NW Mediterranean Sea, one characterized by oligotrophic open-sea waters and the other accumulating seagrass leaf litter, together with an experimental examination of TEP release by seagrass litter. TEP concentrations ranged from 4.6 µg XG Eq L−1 to 90.6 µg XG Eq L−1, with mean (±SE) values of 38.7 (±2.02) µg XG Eq L−1 in the site devoid of seagrass litter, whereas the coastal beach site accumulating leaf litter had > 10-fold mean TEP concentrations of 487.02 (±72.8) µg XG Eq L−1 . Experimental evaluation confirmed high rates of TEP production by P. oceanica litter, allowing calculations of the associated TEP yield. We demonstrated that P. oceanica is an important source of TEP to the Mediterranean Sea, contributing an estimated 0.10 Tg C as TEP annually. TEP release by P. oceanica seagrass explains the elevated TEP concentration relative to the low chlorophyll a concentration in the Mediterranean Sea.

Ancient Egyptian Medicine: A Systematic Review

Samuel Adu-Gyamfi

2015-12-01

Full Text Available Our present day knowledge in the area of medicine in Ancient Egypt has been severally sourced from medical papyri several of which have been deduced and analyzed by different scholars. For educational purposes it is always imperative to consult different literature or sources in the teaching of ancient Egypt and medicine in particular. To avoid subjectivity the author has found the need to re-engage the efforts made by several scholars in adducing evidences from medical papyri. In the quest to re-engage the efforts of earlier writers and commentaries on the medical papyri, we are afforded the opportunity to be informed about the need to ask further questions to enable us to construct or reconstruct both past and modern views on ancient Egyptian medical knowledge. It is this vocation the author sought to pursue in the interim, through a preliminary review, to highlight, comment and reinvigorate in the reader or researcher the need for a continuous engagement of some pertinent documentary sources on Ancient Egyptian medical knowledge for educational and research purposes. The study is based on qualitative review of published literature. The selection of those articles as sources was based on the focus of the review, in order to purposively select and comment on articles that were published based either on information from a medical papyrus or focused on medical specialization among the ancient Egyptians as well as ancient Egyptian knowledge on diseases and medicine. It was found that the Egyptians developed relatively sophisticated medical practices covering significant medical fields such as herbal medicine, gynecology and obstetrics, anatomy and physiology, mummification and even the preliminary form of surgery. These practices, perhaps, were developed as remedies for the prevailing diseases and the accidents that might have occurred during the construction of their giant pyramids. It must be stated that they were not without flaws. Also, the

Full Text Available Ecosystem services provided by oceans and seas support most human needs but are threatened by human activities. Despite existing maps illustrating human impacts on marine ecosystems, information remains either large-scale but rough and insufficient for stakeholders (1 km² grid, lack of data along the coast or fine-scale but fragmentary and heterogeneous in methodology. The objectives of this study are to map and quantify the main pressures exerted on near-coast marine ecosystems, at a large spatial scale though in fine and relevant resolution for managers (one pixel = 20 x 20 m. It focuses on the French Mediterranean coast (1,700 km of coastline including Corsica at a depth of 0 to 80 m. After completing and homogenizing data presently available under GIS on the bathymetry and anthropogenic pressures but also on the seabed nature and ecosystem vulnerability, we provide a fine modeling of the extent and impacts of 10 anthropogenic pressures on marine habitats. The considered pressures are man-made coastline, boat anchoring, aquaculture, urban effluents, industrial effluents, urbanization, agriculture, coastline erosion, coastal population and fishing. A 1:10 000 continuous habitat map is provided considering 11 habitat classes. The marine bottom is mostly covered by three habitats: infralittoral soft bottom, Posidonia oceanica meadows and circalittoral soft bottom. Around two thirds of the bottoms are found within medium and medium high cumulative impact categories. Seagrass meadows are the most impacted habitats. The most important pressures (in area and intensity are urbanization, coastal population, coastal erosion and man-made coastline. We also identified areas in need of a special management interest. This work should contribute to prioritize environmental needs, as well as enhance the development of indicators for the assessment of the ecological status of coastal systems.

Scenarios in the development of Mediterranean cyclones

Directory of Open Access Journals (Sweden)

M. Romem

2007-07-01

Full Text Available The Mediterranean is one of the most cyclogenetic regions in the world. The cyclones are concentrated along its northern coasts and their tracks are oriented more or less west-east, with several secondary tracks connecting them to Europe and to North Africa. The aim of this study is to examine scenarios in the development of Mediterranean cyclones, based on five selected winter seasons (October–March. We detected the cyclones subjectively using 6-hourly Sea-Level Pressure maps, based on the NCAR/NCEP reanalysis archive.

HMSO (1962 has shown that most Mediterranean cyclones (58% enter the Mediterranean from the Atlantic Ocean (through Biscay and Gibraltar, and from the south-west, the Sahara Desert, while the rest are formed in the Mediterranean Basin itself. Our study revealed that only 13% of the cyclones entered the Mediterranean, while 87% were generated in the Mediterranean Basin. The entering cyclones originate in three different regions: the Sahara Desert (6%, the Atlantic Ocean (4%, and Western Europe (3%.

The cyclones formed within the Mediterranean Basin were found to generate under the influence of external cyclonic systems, i.e. as "daughter cyclones" to "parent cyclones" or troughs. These parent systems are located in three regions: Europe (61%, North Africa and the Red Sea (34.5% and the Mediterranean Basin itself (4.5%. The study presents scenarios in the development of Mediterranean cyclones during the winter season, emphasizing the cyclogenesis under the influence of various external forcing.

The large difference with respect to the findings of HMSO (1962 is partly explained by the dominance of spring cyclones generating in the Sahara Desert, especially in April and May that were not included in our study period.

Origin and biogeography of the deep-water Mediterranean Hydromedusae including the description of two new species collected in submarine canyons of Northwestern Mediterranean

Directory of Open Access Journals (Sweden)

J. M. Gili

1998-06-01

Full Text Available Two new species of hydromedusae (Foersteria antoniae and Cunina simplex are described from plankton collected in sediment traps placed in the Lacaze-Duthiers Submarine Canyon and along Banyuls-sur-Mer coast (northwestern Mediterranean. The Mediterranean hydromedusan deep-water fauna contains 41 species which represent 45.5 % of the world-wide deep-sea hydromedusae fauna (90 and 20% of the total number of Mediterranean hydromedusae (204. The Mediterranean deep-water hydromedusan fauna is characterised by a large percentage of holoplanktonic species (61%, mainly Trachymedusae. Nevertheless, contrary to the general opinion, the percentage of meroplanktonic species is equally high. The most original features of this fauna lies however in the importance of the number of endemic species (22% and in the fact that the majority of them are meroplanktonic Leptomedusae with a supposed bathybenthic stage. Some of the endemic species could still represent relics of the primitive Tethys fauna having survived to the Messinian crisis. The origin of the Mediterranean deep-water hydromedusan fauna is discussed and a general hypothesis is proposed.

Full Text Available Objective: To examine the antioxidant and the antimicrobial activities of the marine seaweeds Padina pavonica (P. pavonica and Enteromorpha sp. from the Tunisian Mediterranean coast. Methods: The acetone and water were used for algae extraction to envisage the antimicrobial activity versus Gram-negative (Escherichia coli and Pseudomonas aeruginosa, Gram-positive bacteria (Staphylococcus aureus and Enterococcus faecalis and against four Candida. The microdilution method was used to evaluate this activity. In vitro, total phenolic content and the antioxidant activity including 1,1-diphenyl-2-picrylhydrazyl (DPPH radical scavenging and 2,2'-azino-bis-(3-ethylbenthiazoline-6-sulfonic acid (ABTS were also studied. Results: The highest amount of phenolic compound was found in the P. pavonica acetonic extract [(90.61 ± 0.11 mg catechin equivalent/g extract]. This brown algae sample demonstrated greater DPPH and ABTS radical scavenging ability potential in comparison to other green seaweed, Enteromorpha sp. The maximum antimicrobial activity was shown by the P. pavonica acetonic extract against all the pathogenic strains tested (minimum inhibitory concentrations = minimum inhibitory bactericidal = minimum inhibitory fungicidal concentrations = 0.04 mg/mL. Those activities might be due to phenolic substances present in this fraction. Conclusions: The present results highlight the possible use of P. pavonica as source of antioxidant and antimicrobial compounds.

The first record in the Mediterranean Sea of the invasive aorid amphipod crustacean Grandidierella bonnieroides is presented. A widespread circumtropical species, recorded off the Saudi coast of the Arabian Gulf, the Red Sea and the Suez Canal, it may have been introduced into the Mediterranean through the Suez Canal. This tube-builder species of soft bottoms recently established a population in the polluted Haifa Bay, Israel. Further, this is the first Mediterranean record of the genus.

The most abundant of the collagen protein family, type I collagen is encoded by the COL1A2 gene. The COL1A2 restriction fragment length polymorphisms (RFLPs) EcoRI, RsaI and MspI in samples from several different central-eastern Mediterranean populations were analysed and found to be potentially informative anthropogenetic markers. The objective was to define the genetic variability of COL1A2 in the central-eastern Mediterranean and to shed light on its genetic distribution in human groups over a wide geographic area. PCR-RFLP analysis of EcoRI, RsaI and MspI polymorphisms of the COL1A2 gene was performed on oral swab and blood samples from 308 individuals from the central-eastern Mediterranean Basin. The genetic similarities among these groups and other populations described in the literature were investigated through correspondence analysis. Single-marker data and haplotype frequencies seemed to suggest a genetic homogeneity within the European populations, whereas a certain degree of differentiation was noted for the Egyptians and the Turks. The genetic variability in the central-eastern Mediterranean area is probably a result of the geographical barrier of the Mediterranean Sea, which separated European and African populations over time.

The Red Sea is considered one of the youngest oceanic systems, with unique physical, geochemical and biological characteristics. Tourism, industrialization, extensive fishing, oil processing and shipping are extensive sources of pollution in the Red Sea. We analyzed the geochemical characteristics and microbial community of sediments along the Egyptian coast of the Red Sea. Our sites mainly included 1) four ports used for shipping aluminum, ilmenite and phosphate; 2) a site previously reported to have suffered extensive oil spills; and 3) a site impacted by tourism. Two major datasets for the sediment of ten Red Sea coastal sites were generated; i) a chemical dataset included measurements of carbon, hydrogen, nitrogen and sulfur, metals and selected semi-volatile oil; and ii) a 16S rRNA Pyrotags bacterial metagenomic dataset. Based on the taxonomic assignments of the 16S rRNA Pyrotags to major bacterial groups, we report 30 taxa constituting an Egyptian Red Sea Coastal Microbiome. Bacteria that degrade hydrocarbons were predominant in the majority of the sites, particularly in two ports where they reached up to 76% of the total identified genera. In contrast, sulfate-reducing and sulfate-oxidizing bacteria dominated two lakes at the expense of other hydrocarbon metabolizers. Despite the reported "Egyptian Red Sea Coastal Microbiome," sites with similar anthropogenic pollutants showed unique microbial community abundances. This suggests that the abundance of a specific bacterial community is an evolutionary mechanism induced in response to selected anthropogenic pollutants. Copyright © 2016 Elsevier Ltd.

Three species of the bunocotyline genus Saturnius Manter, 1969 are described from the stomach lining of mugilid fishes of the Mediterranean and Black Seas. Two of the species are new: S. minutus n. sp. occurs in Mugil cephalus off the Mediterranean coast of Spain; and S. dimitrovi n. sp., a parasite of M. cephalus off the Bulgarian Black Sea coast and the Spanish Mediterranean coast, was originally described as S. papernai by Dimitrov et al. (1998). In addition, S. papernai Overstreet, 1977 is redescribed from M. cephalus off the Spanish Mediterranean coast and from Liza aurata and L. saliens off the Bulgarian Black Sea coast. The three species are distinguished morphometrically using univariate and multivariate analyses. These results were verified using Linear Discriminant Analysis which correctly allocated all specimens to their species designations based on morphology (i.e. 100% successful classification rate) and assigned almost all specimens to the correct population (locality). The following variables were selected for optimal separation between samples: the length of the forebody, ventral sucker and posterior testis, the length and width of the posteriormost pseudosegment, and the width of the muscular flange at ventral sucker level.

Ahmed Mahmoud Yosri

2013-12-01

Full Text Available In 2008 the first Egyptian booklet Machine Readable Passport/ MRP has been issued and its security and informative standard quality levels were proved in a research published in 2011. Here the durability profiles of the Egyptian MRP have been evaluated. Seven mechanical durability tests were applied on the Egyptian MRP. Such tests are specified in the International Civil Aviation Organization / ICAO standard requirements documents. These seven very severe durability tests resulted in that the Egyptian MRP has achieved better & higher results than the values detected in ICAO-Doc N0232: Durability of Machine Readable Passports - Version: 3.2. Hence, this research had proved the complete conformance between the Egyptian MRP mechanical durability profiles to the international requirements. The Egyptian booklet MRP doesn’t need any obligatory modification concerning its mechanical durability profiles.

Full Text Available Rht8 is widely used in dry environments such as Mediterranean regions where it increases plant adaptability. Variation at the Gatersleben wheat microsatellite Xgwm261 locus, whose 192-bp allele closely linked to the dwarfing gene Rht8, on chromosome 2D within 0.6 cM, was used to screen thirty Egyptian bread wheat genotypes released from (1947-2004 to assess the variation at this locus. There were three microsatellite allelic variants based on size. Screening of this wheat collection showed that the three alleles Xgwm261-165, Xgwm261-174 and Xgwm261-192 bp were the most frequent. The highest allele frequency was observed for a Xgwm261-165 bp fragment (65.52% followed by a Xgwm261-174 bp fragment (24.14%. However, the allele frequency of a Xgwm261-192 bp fragment among these wheat genotypes was 10.34%. The percentage distribution of dwarfing alleles for the microsatellite locus Xgwm261 in the Egyptian wheat breeding programs was 30, 20, 20 and 30% for the wheat breeding program Giza, Sakha, Gemmiza and Sids, respectively. PIC for Xgwm261 was 0.527. Genetic heritage of Egyptian genotypes at the microsatellite locus Xgwm261 is consequence of new parental components usage, carriers short plant and early maturity attributes and consequent selection progeny with these traits in breeding programs. The present study will be helpful in characterization Egyptian wheat genotypes, as well as in accurate selection of parents for wheat breeding program in Egypt.

We have developed a new coastal database for the Mediterranean basin that is intended for coastal impact and adaptation assessment to sea-level rise and associated hazards on a regional scale. The data structure of the database relies on a linear representation of the coast with associated spatial assessment units. Using information on coastal morphology, human settlements and administrative boundaries, we have divided the Mediterranean coast into 13 900 coastal assessment units. To these units we have spatially attributed 160 parameters on the characteristics of the natural and socio-economic subsystems, such as extreme sea levels, vertical land movement and number of people exposed to sea-level rise and extreme sea levels. The database contains information on current conditions and on plausible future changes that are essential drivers for future impacts, such as sea-level rise rates and socio-economic development. Besides its intended use in risk and impact assessment, we anticipate that the Mediterranean Coastal Database (MCD) constitutes a useful source of information for a wide range of coastal applications.

2013-01-01

Full Text Available Abstract Background Artisanal fisheries in the Mediterranean, especially in Italy, have been poorly investigated. There is a long history of fishing in this region, and it remains an important economic activity in many localities. Our research entails both a comprehensive review of the relevant literature and 58 field interviews with practitioners on plants used in fishing activities along the Western Mediterranean Italian coastal regions. The aims were to record traditional knowledge on plants used in fishery in these regions and to define selection criteria for plant species used in artisanal fisheries, considering ecology and intrinsic properties of plants, and to discuss the pattern of diffusion of shared uses in these areas. Methods Information was gathered both from a general review of ethnobotanical literature and from original data. A total of 58 semi-structured interviews were carried out in Liguria, Latium, Campania and Sicily (Italy. Information on plant uses related to fisheries were collected and analyzed through a chi-square residual analysis and the correspondence analysis in relation to habitat, life form and chorology. Results A total of 60 plants were discussed as being utilized in the fisheries of the Western Italian Mediterranean coastal regions, with 141 different uses mentioned. Of these 141 different uses, 32 are shared among different localities. A multivariate statistical analysis was performed on the entire dataset, resulting in details about specific selection criteria for the different usage categories (plants have different uses that can be classified into 11 main categories. In some uses, species are selected for their features (e.g., woody, or habitat (e.g., riverine, etc. The majority of uses were found to be obsolete (42% and interviews show that traditional fishery knowledge is in decline. There are several reasons for this, such as climatic change, costs, reduction of fish stocks, etc. Conclusions Our research

Mesozoic carbonate-siliciclastic platform to basin systems of a South Tethyan margin (Egypt, East Mediterranean)

2015-04-01

The Mesozoïc Egyptian margin is the south margin of a remnant of the Neo-Tethys Ocean, at the African northern plate boundary. East Mediterranean basin developed during the late Triassic-Early Jurassic rifting with a NW-SE opening direction (Frizon de Lamotte et al., 2011). During Mesozoïc, Egypt margin was a transform margin with a NW-SE orientation of transform faults. In the Eastern Mediterranean basin, Mesozoïc margins are characterized by mixed carbonate-siliciclastics platforms where subsidence and eustacy are the main parameters controlling the facies distribution and geometries of the platform-to-basin transition. Geometries and facies on the platform-slope-basin system, today well constrained on the Levant area, where still poorly known on the Egyptian margin. Geometries and stratigraphic architecture of the Egyptian margin are revealed, thanks to a regional seismic and well data-base provided by an industrial-academic group (GRI, Total). The objective is to understand the sismostratigraphic architecture of the platform-slope-basin system in a key area from Western Desert to Nile delta and Levant margin. Mapping of the top Jurassic and top Cretaceous show seismic geomorphology of the margin, with the cartography of the hinge line from Western Desert to Sinaï. During the Jurassic, carbonate platform show a prograding profile and a distally thickening of the external platform, non-abrupt slope profiles, and palaeovalleys incisions. Since the Cretaceous, the aggrading and retrograding mixed carbonate-siliciclastic platform show an alternation of steep NW-SE oblique segments and distally steepened segments. These structures of the platform edge are strongly controlled by the inherited tethyan transform directions. Along the hinge line, embayments are interpreted as megaslides. The basin infilling is characterised by an alternation of chaotic seismic facies and high amplitude reflectors onlaping the paleoslopes. MTC deposits can mobilize thick sedimentary

2018-04-01

A study on Trace Elements (TE) from sea urchin gonads has been conducted in the western Mediterranean Sea. Contamination data were used to determine a Trace Method Pollution Index (TEPI). TE concentrations varied considerably depending on the location of the sampling stations. The results showed that five trace elements (Zn, Fe, As, Al, Cu) are ubiquitous. The geographical area considered (Corsica) represents an important range of environmental conditions and types of pressure that can be found in the western Mediterranean Sea. TEPI was used to classify the studied sites according to their degree of contamination and allowed reliable comparison of TE contamination between local and international sites. TE contamination of the western Mediterranean Sea displayed a north-to-south gradient, from the Italian coasts down through the insular Corsican coasts to the north African littoral. Due to the increasing environmental pressure on the Mediterranean Sea, a regular monitoring of TE levels in marine organisms is necessary to prevent any further environmental deterioration.

This paper is in two parts. Part one is about the methods for analyzing transuranium elements particularly the development of an analytical process for plutonium and for perfecting an Americium analyzing method, capable of treating samples of 200 litres of sea water, 100 grams of sediment and 100 grams of biological matter. Part two concerns the in situ determinations carried out within the scope of the study on the distribution and behaviour of transuranium elements in the Mediterranean sea. The high sea studies concerned the effects of atmospheric fall out and the vertical distribution of Pu and Am. Studies along the coasts enabled a quantitative study to be made of the contribution of rivers to the Mediterranean and to study the distribution of Pu along the French Mediterranean coast line [fr

"The main objective of this paper is to evaluate the impact of the large remittances made by Egyptian migrants to their home country on the Egyptian economy. In order to study this impact, we use the implications of the standard Keynesian model. We estimated the structural equations of the model using annual data for the Egyptian economy over the period from 1970 to 1984.... The results suggest that remittances have had a strong positive impact on GNP in Egypt." The authors note that remittances especially affect private consumption spending. Policy implications concerning labor migration are discussed. (SUMMARY IN FRE AND SPA) excerpt

Collado-Vázquez, S; Carrillo, J M

2014-09-01

Medicine and literature have been linked from ancient times; proof of this shown by the many doctors who have made contributions to literature and the many writers who have described medical activities and illnesses in their works. An example is The Egyptian, the book by Mika Waltari that provides a masterly narration of the protagonist's medical activity and describes the trepanation technique. The present work begins with the analysis of trepanations since prehistory and illustrates the practice of the trepanation in The Egyptian. The book mentions trepanation frequently and illustrates how to practice it and which instruments are required to perform it. Trepanation is one of the oldest surgical interventions carried out as treatment for cranial trauma and neurological diseases, but it also had the magical and religious purpose of expelling the evil spirits which caused the mental illness, epilepsy, or migraine symptoms. Trepanation is a surgical practice that has been carried out since prehistory to treat post-traumatic epilepsy, migraine, and psychiatric illness. The Egyptian is a book that illustrates the trepan, the trepanation technique, and the required set of instruments in full detail. Copyright © 2010 Sociedad Española de Neurología.

Full Text Available The striped eel catfish, Plotosus lineatus (Thunberg, 1787, is recorded for the first time from the eastern Mediterranean coast of Israel. Seventeen specimens of this highly-venomous fish were caught by a commercial trawler at depths of 20 m. This species´ occurrence in the Mediterranean is the result of migration from the Red Sea via the Suez Canal (Lessepsian migration.

Simulation and analysis of the mesoscale circulation in the northwestern Mediterranean Sea

Directory of Open Access Journals (Sweden)

V. Echevin

Full Text Available The large-scale and mesoscale circulation of the northwestern Mediterranean Sea are simulated with an eddy-resolving primitive-equation regional model (RM of 1/16° resolution embedded in a general circulation model (GM of the Mediterranean Sea of 1/8° resolution. The RM is forced by a monthly climatology of heat fluxes, precipitation and wind stress. The GM, which uses the same atmospheric forcing, provides initial and boundary conditions for the RM. Analysis of the RM results shows that several realistic features of the large-scale and mesoscale circulation are evident in this region. The mean cyclonic circulation is in good agreement with observations. Mesoscale variability is intense along the coasts of Sardinia and Corsica, in the Gulf of Lions and in the Catalan Sea. The length scales of the Northern Current meanders along the Provence coast and in the Gulf of Lions’ shelf are in good agreement with observations. Winter Intermediate Water is formed along most of the north-coast shelves, between the Gulf of Genoa and Cape Creus. Advection of this water by the mean cyclonic circulation generates a complex eddy field in the Catalan Sea. Intense anticyclonic eddies are generated northeast of the Balearic Islands. These results are in good agreement with mesoscale activity inferred from satellite altimetric data. This work demonstrates the feasibility of a down-scaling system composed of a general-circulation, a regional and a coastal model, which is one of the goals of the Mediterranean Forecasting System Pilot Project.

Mediterranean diet and colorectal cancer: A systematic review.

Science.gov (United States)

Farinetti, Alberto; Zurlo, Valeria; Manenti, Antonio; Coppi, Francesca; Mattioli, Anna Vittoria

Colorectal cancer is the third most common cancer worldwide, especially in developed countries where an estimated 60% of all cases occur. There is evidence of a higher risk for CRC in Western society, where people tend to eat more red and processed meat than those living along the Mediterranean coast, who have a decreased overall cancer mortality, which is correlated to their eating habits, such as Mediterranean diet. The aim of this review was to evaluate the correlation between three components of the Mediterranean diet (olive oil, red wine, and tomatoes) and incidence and progression of colorectal cancer. As such, we conducted a literature search using keywords "colorectal cancer," "dietary pattern," "Mediterranean diet," "olive oil," "protective effects," "resveratrol," and "lycopene." Olive oil polyphenols, red wine resveratrol, and tomato lycopene showed several characteristics in vitro that interfere with molecular cancer pathways. At the same time, many clinical studies have reported an association of these components with a reduction in cancer initiation and progression. More clinical studies are needed to identify the precise dose and administration of single agents or their combination to produce a coadjutant treatment to those already applied in chemoprevention and oncologic treatment.

2015-12-01

Full Text Available Majority of the alien foraminifers recorded in the eastern Mediterranean are Indo-Pacific originated and entered the Mediterranean via Suez Canal. In this study, current literature on the alien benthic foraminiferal fauna of the eastern Mediterranean was reviewed and the main dispersal pathways are determined. Distribution patterns of the alien species suggests that most of the species are introduced via Suez Canal and expand their range of distributions in a counter-clockwise manner by the general surface currents of the eastern Mediterranean. However, not all, but some of the species have also been dispersed westwards along the North African coast and reached central Mediterranean. Locally abundant records of Euthymonacha polita (Chapman, Coscinospira acicularis (Batsch and Amphistegina lobifera in the Aegean Sea indicates that Suez Canal may not be the only vector for the Indo-Pacific species to enter eastern Mediterranean and submarine springs help these thermophilic species to form establish populations in cool waters of the northern Aegean and the Sea of Marmara

Occupational stress (OS) among teachers predispose to depression and anxiety. No study was done to assess these problems among Egyptian teachers. This study aimed to assess the prevalence of OS, depression and anxiety among Egyptian teachers. A cross sectional study was done on 568 Egyptian teachers. The respondents filled a questionnaire on personal data, and the Arabic version of the Occupational Stress Index (OSI), the Arabic validated versions of Taylor manifest anxiety scale and the Beck Depression Inventory (BDI) were used to assess OS, anxiety and depression respectively. The prevalence of OS, anxiety and depression among teachers was (100%, 67.5% and 23.2%) respectively. OS, anxiety and depression scores were significantly higher among teachers with an age more than 40years, female teachers, primary school teachers, those with inadequate salary, higher teaching experience, higher qualifications and higher workload. A significant weak positive correlation was found between OS scores and anxiety and depression scores. This study indicated the need for future researches to address risk factors of OS and mental disorders among Egyptian teachers, and the need of periodical medical evaluation of teachers and medical and psychological support for the identified cases.

Measurements of natural radionuclides concentrations ( 226 Ra, 232 Th and 40 K) in sediments collected from sea, rivers or ocean is significant to protect the sea water ecosystem and to human health from radiation. Thirty-three sample of sediment have been collected from four ports in the Red Sea coast, Egypt for investigation by gamma-ray spectrometer using NaI(Tl) detector. The average and range activity concentrations of 226 Ra, 232 Th and 40 K were 26(5-58), 19(4-33) and 458(16-2665)Bqkg -1 in Quseir Harbour, 30(14-53), 20(14-34) and 430(378-511)Bqkg -1 in Abu-Tartour Harbour. However, the average and range activity concentrations were 23(14-35), 21(15-32), and 602(327-821)Bqkg -1 in Touristic Harbour and 14(5-26), 13(2-23) and 489(36-950)Bqkg -1 in Hurghada harbour. These results were compared with reported ranges in the literature from other location in the world. The radiation hazard parameters; radium equivalent activity annual dose, external hazard were also calculated and compared with the recommended levels by UNSCEAR reports. Eight heavy metals (Fe, Mn, Ni, Co, Zn, Cu, Pb and Cd) have been measured and analyzed by atomic absorption spectrometer. The concentration for the investigated heavy metals overtakes the allowable limits recommended by the Canadian Environmental Quality Guidelines. Because there are no existing databases for the natural radioactivity in the sediment samples from Egyptian Red Sea ports, our results are a start to establishing a database for Red Sea harbours environment.

A series of severe drought events in the Mediterranean region over the past two decades has posed a threat on both human society and biosystem. Holocene hydrological dynamics can offer valuable clues for understanding future climate and making proper adaption strategy. Here, we present a decadal-resolved stalagmite record documenting various hydroclimatic fluctuations in the north central Mediterranean region since the middle Holocene. The stalagmite δ18O sequence shows dramatic instability, characterized by abrupt shifts between dry and wet conditions Mycenaean Greece, Akkadian Empire, Egyptian Old Kingdom, and Uruk, occurred during the drought events, suggesting an important role of climate impact on human civilization. The unstable hydroclimate evolution is related to transferred North Atlantic Oscillation states. Rate of rapid transfer of precipitation patterns, which can be pin-pointed by our good chronology, improves the prediction to future climate changes in North Atlantic region. We also found that a strong correlation between this stalagmite δ18O and sea surface temperatures especially in Pacific Ocean. This agreement suggests a distant interregional climate teleconnection.

2003-06-01

Full Text Available A single adult male specimen of the East Asian crab Hemigrapsus sanguineus (de Haan, 1835 was collected in August 2001 in the northern Adriatic Sea along the northwest coast of the peninsula of Istra. This is the first record of this genus and species from the Mediterranean Sea. Previously, Hemigrapsus sanguineus had been reported to invade the Atlantic coasts of North America and of western France, while the congeneric East Asian species, Hemigrapsus penicillatus (de Haan, 1835, has established breeding populations along the Atlantic coast of Europe. The current absence of Hemigrapsus sanguineus in southern Europe and the western Mediterranean suggests an independent human-mediated introduction of the Croatian specimen. Preliminary genetic analyses reveal that specimens from Istra, North America, and Japan have identical DNA haplotypes corresponding to the mitochondrial large subunit rRNA gene (16S mtDNA, while the homologous sequence from a specimen of Taiwan differs in two out of 525 nucleotides.

The consumption of edible fish (e.g., Siganus spp) was assumed to have caused ciguatera poisoning at an atypical site, the eastern Mediterranean. This pilot study assesses the presence of ciguatoxin-like substances in edible fish on the eastern Mediterranean coast of Israel. Samples of Siganus rivulatus from polluted seawater (Haifa Bay), Siganus rivulatus from relatively clean seawater (Dor), and fish from the freshwater Sea of Galilee not inhabited by toxic algae were analyzed during summertime. Ciguatoxin-like substances were tested by a membrane immunobead assay that yields a color reaction (positive, weakly positive, negative). Significantly more large and small fish from Haifa Bay yielded positive color reactions compared to fish from Dor. Sea of Galilee fish gave no positive color reactions. Our results suggest the presence of ciguatoxin-like substances in edible fish of the eastern Mediterranean. Additional analyses are needed to determine whether these substances are ciguatoxins or related polyethers.

Only five of fourteen species of Fucales reported at the end of the XIXth century are currently present in the Albères Coast (France, NW Mediterranean). According to historical data there has been a steady decrease of all the populations since the 1940s. Seven taxa now extinct (Cystoseira crinita, Cystoseira barbata, Cystoseira foeniculacea f. tenuiramosa, Cystoseira spinosa, Cystoseira spinosa var. compressa, Sargassum hornschuchii and Sargassum vulgare) were considered frequent and some of them were the dominant and engineering species in several phytobenthic assemblages. Moreover, only one of the five species left, shows no signs of regression (Cystoseira compressa), two are considered as rare (Cystoseira caespitosa, Cystoseira zosteroides), and one is very rare (Cystoseira elegans). Cystoseira mediterranea, a species that was reported to make a continuous belt along the shores of the Albères coast, has almost disappeared from some areas. Overgrazing by sea urchins, outcompetition by mussels, habitat destruction, scientific research sampling and, probably, human trampling and chemical pollution are to be blamed for the decline of populations thriving in shallow waters. Deep-water species have been affected by an increase in water turbidity and, probably, chemical pollution and direct plant destruction attributed to net fishing. If degradation of the environmental conditions continues, the remaining Cystoseira species will face a most unwelcome prospect. Even after the removal of the causes that led to its die-off, natural restoration of extinct species seems not to be possible because the decline has also affected populations from nearby areas and zygotes are unable to disperse over long distances. Urgent management actions have to be designed in order to improve the current situation of the populations of Fucales in the Albères coast.

[Early Egyptian forerunners of the Paranatellonta?].

The term "paranatellonta" is well-known in greek astrological literature. It designates stars either rising together with the sun or being in other conspicuous positions to it. Tentatively, a forerunner of this conception is identified in an egyptian depiction attested several times from the 13th century BC onwards. There, "gods" are depicted who are defined by their positions in regard to the sun-god. It seems possible to connect their positions with the typical meanings of the word paranatellonta. Some reflections on the contribution of Egypt to hellenistic astrology are added, including some references to the largely unpublished corpus of demotic egyptian astrological texts.

The study of acetabular morphology has shown that there are geographic differences in the morphology and prevalence of acetabular dysplasia among different ethnic groups. However, few data exist on the shape of the acetabulum in various populations around the world. In this study, we examined samples of pelvic radiographs from Egyptian adults. Acetabular dysplasia in adults is characterized by a shallow and relatively vertical acetabulum.The aim of this study was to examine acetabular morphology to determine the prevalence of hip dysplasia in adult Egyptians. This included 244 adults, 134 men and 110 women between 18 and 60 years, who were used to measure center edge angle, acetabular Sharp angle, acetabular head index on anteroposterior radiographic views of the hip joints, and vertical center anterior margin angle on false profile views. The radiographs were taken of patients with no hip complaints at Tanta University Hospital.The results were statistically studied according to the age, height, and weight of patients. The prevalence of acetabular dysplasia was 2.25% for Egyptian men and 3.6% for women with respect to center edge angles, vertical center anterior margin angle, and acetabular head index.We concluded that gender variations in the morphology of the acetabulum and sex influences geometrical measurements of the acetabulum. Egyptian women were more dysplastic than men using the 4 parameters of hip measurements. There are also racial variations in hip morphology. Copyright 2011, SLACK Incorporated.

Egypt is famously known for its Nile and pyramids, yet not many people know that Egypt made possible the origin of the anatomical sciences. Several ancient papyri guide us through the Egyptians' exploration of the human body and how they applied anatomical knowledge to clinical medicine to the best of their knowledge. It is through records, such as the Edwin Smith, Ebers, and Kahun papyri and other literature detailing the work of the Egyptian embalmers, physicians, and Greek anatomists, that we are able to take a glimpse into the evolution of the anatomical sciences from 3000 B.C. to 250 B.C. It is through the Egyptian embalmer that we were able to learn of some of the first interactions with human organs and their detailed observation. The Egyptian physician's knowledge, being transcribed into the Ebers and Edwin Smith papyri, enabled future physicians to seek reference to common ailments for diagnosing and treating a variety of conditions ranging from head injuries to procedures, such as trans-sphenoidal surgery. In Alexandria, Herophilus, and Erasistratus made substantial contributions to the anatomical sciences by beginning the practice of human dissection. For instance, Herophilus described the anatomy of the heart valves along with Erasistratus who demonstrated how blood was prevented from flowing retrograde under normal conditions. Hence, from various records, we are able to unravel how Egypt paved the road for study of the anatomical sciences. Copyright © 2011 Wiley-Liss, Inc.

Purpose of the National Conference on Energy and Environment is to examine the energy cycle from the environmental, economic and employment standpoints to provide with a new frame of reference all actors concerned. The choice of the Mediterranean Sea as a subject in one of the themes under discussion, apart from being obviously grounded on Italy's central location in it, is explained by the number of critical factors showing in the area; among which energy aspects (as regards energy production, transportation and use), the high level of urbanization of its coasts, impact and conflicts for resource utilisation generated by and between economic activities - agriculture, industry, fisheries, tourism, sea freighting, and so on - and the uniqueness and variety of Mediterranean ecosystems

2017-12-01

Full Text Available Cutandia maritima is a circum-Mediterranean species that inhabits sandy dunes along the coast line. It is fairly frequent on the western Adriatic coast but fairly rare and possibly even non-native in the east. In Croatia, it was discovered in 1990 in Crnika Bay on the island of Rab, which was considered until 2005 to be the only site on the eastern Adriatic coast from the Gulf of Trieste in the north to Corfu in the south. In 2009, the species was briefly reported for Velika plaža (Long Beach in Ulcinj (Montenegro but without details about the habitat type and synecology. The aim of this paper is thus to provide a deeper insight into the ecology and synecology of C. maritima in the eastern Adriatic part of the distribution area. On Velika plaža in Ulcinj, the species was found along the whole sea-inland gradient of sand dunes, in various types of vegetation: [1210] - annual vegetation of drift lines, [2110] - embryonic shifting dunes, [2120] - shifting dunes with Ammophila arenaria (white dunes, [2220] - dunes with Euphorbia terracina, [2130*] - fixed coastal dunes with herbaceous vegetation (grey dunes, and also [2190] - humid dune slacks.

Homer and Herodotus to Egyptian medicine.

Science.gov (United States)

Rossi, Marco

2010-12-01

Egyptian medicine is the base of Greek medicine. Egyptian people and their medical knowledge are often mentioned in the Iliad and Odyssey of Homer (VIII sec. BCE). Many Greek doctors, such as Melampus, Asclepius as well as Hippocrates visited Egypt to study and understand medicine. This work intends to focus particularly on Homer, Herodotus and Plutarch's letters, where the importance of Egypt in religion, science and medicine is clear. Herodotus (484-420 BCE) in the second book of "The Histories" describes Egypt and the medical knowledge of its doctors. Plutarch (I-II sec CE) in "The virtues of Sparta" and "Life of Lycurgus", tells about an energy beverage, named nepenthe, made with drugs from Egypt.

Improving the wave forecast in the Catalan Coast

Pallares, Elena; Sanchez-Arcilla, Agustin; Espino, Manuel

2014-05-01

This study has been motivated by the limited accuracy of wave models under short-duration, fetch-limited conditions. This applies particularly to the wave period, and can be illustrated by the case of semi-enclosed domains with highly variable wind patterns such as the Catalan coast in the Spanish Mediterranean. The wave model SWAN version 40.91A is used here in three nested grids covering all the North-western Mediterranean Sea with resolution from 9 to 1 km, forced with high resolution wind patterns from BSC (Barcelona Supercomputing Center) for two study periods, the winter 2010 and the spring 2011. The results are validated in eight locations with different types of instrumentation. In order to improve the results, a modification of the whitecapping well-known formulation of Hasselmann (1974) has been considered. The delta coefficient is increased to adapt the dissipation to the growth rates actually observed in the region. This correction introduces a dependence on the squared wave number, improving the prediction of the energy spectra at lower frequencies. However, one may note that an over-prediction will occur for waves with longer fetch and/or duration. The results obtained show a clear improvement of the mean and peak wave periods for the study area, decreasing considerably the negative bias observed previously, while almost no change is observed in wave height due to the proposed modifications. These results can be generalized to the Spanish Mediterranean coast and could be exported to similar environments, characterized by young/moderate sea wave conditions due to limited fetch and transient wind driving.

Oil spill preparedness in the Mediterranean Sea

International Nuclear Information System (INIS)

Jorigne, E.M.; Wong, K.V.

1993-01-01

Over 15% of the world's consumption of crude oil and refined products is shipped through the Mediterranean Sea each year. The sea is one of the most polluted areas in the world and has areas of high risk for oil spills, notably those places where there is a very narrow passage between coasts or islands. The region also needs to modernize its ports by developing more deballasting facilities, since a large percentage of spill accidents happens during terminal operations. Release of oily wastes from ships is also significant. The World Bank Global Environment Facility trust fund is working on a project to help the southwest Mediterranean countries modernize reception facilities for ballast water, bilge water, and oily waste water. The Regional Marine Pollution Emergency Response Center (REMPEC) in Malta acts as the coordinating center for regional contingency planning for oil spill response. The cost of the port facilities modernization program and oil spill contingency plan implementation for the Mediterranean is estimated at US$444 million. An allocation of costs is suggested which will help those countries needing more financial aid to implement the proposed programs. In the long run, the cost of these programs will be much lower than that of a massive oil spill cleanup. 7 refs., 2 figs., 4 tabs

The egyptian placer deposits - A potential source for nuclear raw materials

1995-10-01

The extensive black sands placer deposits are disconsolately distributed along the northern Mediterranean castle plain of the Nile Delta and Sinai Peninsula. These sediments contain strategic and economic heavy minerals which are required for the industrial exploitation whether for nuclear industry or other metallurgical and engineering industries. They comprise huge reserves of monazite, Zircon, magnetite, ilmenite and garnet. The first three economic minerals contain U, Th, Zr, Hf, Ti and REEs. Thus, monazite assays 0.48% U{sub 3} O{sub 8}, 6.04% (Zr+Hf) 02, 0.06% U{sub 3} O{sub 8} and 0.04% Th O{sub 2}. The beach rutile has 98.64% Ti O{sub 2}. Therefore, the estimated geological reserves of the nuclear materials are enormous. In the light of these data, the nuclear materials Authority has its own programmes for physical and chemical processing of the Egyptian black sands. In the mean time, zircon as a mineral would be used in ceramic industry while rutile as a mineral would be used in welding rods industry. The rare earths oxides cake could be used ferro-silicon alloy. 2 figs., 5 tabs.

Nile damming as plausible cause of extinction and drop in abundance of deep-sea shrimp in the western Mediterranean over broad spatial scales

Science.gov (United States)

Cartes, J. E.; Maynou, F.; Fanelli, E.

2011-11-01

Greatly increased retention of flow in Nile River reservoirs was initiated in 1964, after completion of the Aswan High Dam, which induced important oceanographic changes in the Mediterranean Sea, including deep waters (below a depth of 150 m). Based on an analysis of data series starting in the 1940s/1950s, the giant red shrimp Aristaeomorpha foliacea has become locally extinct off of the Catalonian coasts (and elsewhere in the northwestern Mediterranean) at depths of 400-900 m, with a simultaneous and significant drop in the catches of red shrimp, Aristeus antennatus, in the second half of the 1960s. The extinction and sharp decline of deep-shrimp populations off Catalonian coast (at ca. 3200 km westwards from Nile Delta) followed the 1964 drop in Nile discharge with a delay of ca. 3-5 yrs (breakpoint analysis applied to data series). The breakpoints detected in the second half of 1960s both in Nile runoff and shrimps’ abundance were independent of climatic events in the study area (e.g. changes in NAO) and occurred before the increase in fishing effort off Catalonian coasts (breakpoint in 1973-1974). The Levantine Intermediate Water (LIW), inhabited by A. foliacea in the western Basin, had significant temperature (T) and salinity (S) increases in the 1950-1970 period, and Nile damming has contributed about 45% of the total S increase of Western Mediterranean deep-water masses from the 1960s to the late 1990s (Skliris and Lascaratos, 2004). This had to increase, for instance, LIW salinity at its formation site in the eastern Mediterranean. Nile damming was probably a triggering factor for the extinction/drop in abundance of deep-sea shrimp off Catalonian coasts.

Impact of large-scale circulation changes in the North Atlantic sector on the current and future Mediterranean winter hydroclimate

Science.gov (United States)

Barcikowska, Monika J.; Kapnick, Sarah B.; Feser, Frauke

2018-03-01

The Mediterranean region, located in the transition zone between the dry subtropical and wet European mid-latitude climate, is very sensitive to changes in the global mean climate state. Projecting future changes of the Mediterranean hydroclimate under global warming therefore requires dynamic climate models to reproduce the main mechanisms controlling regional hydroclimate with sufficiently high resolution to realistically simulate climate extremes. To assess future winter precipitation changes in the Mediterranean region we use the Geophysical Fluid Dynamics Laboratory high-resolution general circulation model for control simulations with pre-industrial greenhouse gas and aerosol concentrations which are compared to future scenario simulations. Here we show that the coupled model is able to reliably simulate the large-scale winter circulation, including the North Atlantic Oscillation and Eastern Atlantic patterns of variability, and its associated impacts on the mean Mediterranean hydroclimate. The model also realistically reproduces the regional features of daily heavy rainfall, which are absent in lower-resolution simulations. A five-member future projection ensemble, which assumes comparatively high greenhouse gas emissions (RCP8.5) until 2100, indicates a strong winter decline in Mediterranean precipitation for the coming decades. Consistent with dynamical and thermodynamical consequences of a warming atmosphere, derived changes feature a distinct bipolar behavior, i.e. wetting in the north—and drying in the south. Changes are most pronounced over the northwest African coast, where the projected winter precipitation decline reaches 40% of present values. Despite a decrease in mean precipitation, heavy rainfall indices show drastic increases across most of the Mediterranean, except the North African coast, which is under the strong influence of the cold Canary Current.

An investigation into the ancient Egyptian cultural influences on the Yorubas of Nigeria

Directory of Open Access Journals (Sweden)

Jock M. Agai

2013-07-01

Full Text Available There are many cultural practices that connect ancient Egyptians to the Yorubas and the new interpretation of the Oduduwa legend suggests that the Yorubas have originated or are influenced mainly by the Egyptians. The attestation of Egypt as the main influencer of the Yoruba culture made Egypt significant in the study of the history of the Yoruba people. Some writers are beginning to think that the ancient Egyptians were responsible for introducing and spreading many cultures amongst the Yorubas. As more Yorubas are tracing their origins and the origins of their culture to ancient Egypt, this research investigates whether the Egyptians were the originators and the main spreaders of the afterlife culture in Yorubaland.

Bonaparte's Egyptian Campaign (1798 - 1801), like all other episodes from the Napoleonic era, gave rise to an extensive literature on the subject, but most of all a significant medical literature. This fact is due to many reasons:--an important health service for this expeditionary corps of more than 36.000 men, with two main figures at its hea, Desgenettes and Larrey--but also with valuable subordinates like Assalini, Savaresi, Balme, Pugnet or Barbès.--A Commission for Science and Art, of which a few doctors and surgeons were members, but most of all pharmacists like Boudet or Rouyer--The presence in the field of Ludwig Frank, the nephew of the famous Johann Peter Frank.--The creation in Cairo of an Egyptian Institute and the publication of the masterly Description of Egypt and the establishment of printing houses.--The emergence of the myth of the Orient and its mysteries.--An extensive array of indigenous pathologies, which is characteristic of those countries. For instance: plague, dysentery, yellow fever, Egyptian ophthalmia, as well as more common diseases like tetanus, scurvy or venereal diseases.

Full Text Available Abstract Introduction Familial Mediterranean fever is an autosomal recessive disease that predominantly affects people of the Mediterranean coast. One of the most frequent complications of the disease is amyloidosis. This clinical entity is known as secondary (also called AA amyloidosis. Case presentation In this report, we describe the case of a 33-year-old Turkish man with familial Mediterranean fever and chronic renal insufficiency. He was admitted to our clinic with symptoms of suprarenal insufficiency. The patient died three months later as a result of cardiac arrest. Conclusion Our aim is to make a contribution to the literature by reporting a case of combined insufficiency due to the accumulation of renal and adrenal amyloid in a patient with familial Mediterranean fever, which has very rarely been described in the literature. We hope that adrenal insufficiency, which becomes fatal if not diagnosed and treated rapidly, will come to mind as easily as chronic renal failure in clinical practice.

Sabellaria spinulosa (Polychaeta, Annelida) reefs in the Mediterranean Sea: Habitat mapping, dynamics and associated fauna for conservation management

Bio-constructions by Sabellaria worms play a key functional role in the coastal ecosystems being an engineer organism and for this reason are the object of protection. The most widespread reef building species along Atlantic and Mediterranean coasts is S. alveolata (L.), while the aggregations of S. spinulosa are typically limited to the North Sea coasts. This paper constitutes the first detailed description of unusual large S. spinulosa reefs in the Mediterranean Sea. Defining current health status and evaluating the most important threats and impacts is essential to address conservation needs and design management plans for these large biogenic structures. Present knowledge on Mediterranean reefs of S. alveolata is fragmentary compared to Northeast Atlantic reefs, and concerning S. spinulosa, this paper represents a focal point in the knowledge on Mediterranean reefs of this species. A one-year study on temporal changes in reef structure and associated fauna is reported. The annual cycle of S. spinulosa reef shows a spawning event in winter-early spring, a period of growth and tubes aggregation from spring-early summer to autumn and a degeneration phase in winter. The variations exhibited in density of the worm aggregation and the changes in the reef elevation highlight a decline and regeneration of the structure over a year. The many ecological roles of the S. spinulosa reef were mainly in providing a diversity of microhabitats hosting hard and sandy bottom species, sheltering rare species, and producing biogenic structures able to provide coastal protection. The Mediterranean S. spinulosa reef does not shelter a distinctive associated fauna; however the richness in species composition underscores the importance of the reef as a biodiversity hot-spot. Finally, the roles of the biogenic formations and their important biotic and physical dynamics support the adoption of strategies for conservation of Mediterranean S.spinulosa reefs, according to the aims of the

Full Text Available Specimens of the sipunculan worm Phascolion (Phascolion caupo Hendrix, 1975 have been collected for the first time in the Mediterranean Sea, thus increasing the number of known sipunculan species of up to 36 in this area. They were encountered on soft bottoms from the coast of San Pedro del Pinatar (Western Mediterranean. Thirty specimens were collected at a depth ranging from 32.6 to 37.2 m, mainly in sandy substrata with high load of silt and clays. 80% of the individuals were found inhabiting empty shells of gastropods or empty tubes of serpulid polychaetes.

The Semi-enclosed Mediterranean Sea records various signals of high anthropic pressures from surrounding countries and the industrialized European countries. This is particularly true for oil pollution. Although accounting for 1% of the world's ocean surface, it receives about 25% of the petroleum inputs to the ocean. To achieve a global budget we need to collect information from different parts of the Mediterranean. Particularly, we focus in this paper on the Southern Mediterranean, where data are presently very scarce. In this context, the University of Sfax has undertaken an estimation of hydrocarbon pollution along the coasts of Sfax and Gabès Gulf. Non-aromatic hydrocarbons were analysed in 8 surface sediments by FT/IR and GC/MS. Non-aromatic hydrocarbon concentrations vary in the range 310-1406 microg g(-1) sediments dry weight, which is high, compared to other Mediterranean sites. GC/MS data indicate a large group of unresolved compounds suggesting a petroleum contamination, confirmed by the identification of hopanes with predominant C29 and C30alpha,beta compounds and steranes with predominance of C27 over C28) and C29 compounds.

The Marskhod Egyptian Drill Project

Shaltout, M. A. M.

We describe a possible participation of Egypt in a future Mars rover Mission. It was suggested that Egypt participate through involvement in the design, building and testing of a drill to obtain sub-surface samples. The Space Research Institute of the Russian Academy of Sciences (IKI), formally invited the Egyptian Ministry of Scientific Research to study the concept for potential use on the Russian Mars 2001 Mission. As one of the objectives of the Marskhod mission was the analysis of sub-surface samples, a drilling mechanism in the payload would be essential. The Egyptian expertise in drill development is associated with the archaeological exploration of the Pyramids. A sophisticated drilling system perforated limestone to a depth of 2 m without the use of lubricants or cooling fluids that might have contaminated the Pit's environment. This experience could have been applied to a drill development Mars 2001 mission, which was unfortunately canceled due to economic problems.

Full Text Available Literatures concerning the history of West African peoples published from 1900 to 1970 debate�the possible migrations of the Egyptians into West Africa. Writers like Samuel Johnson and�Lucas Olumide believe that the ancient Egyptians penetrated through ancient Nigeria but Leo�Frobenius and Geoffrey Parrinder frowned at this opinion. Using the works of these early�20th century writers of West African history together with a Yoruba legend which teaches�about the origin of their earliest ancestor(s, this researcher investigates the theories that the�ancient Egyptians had contact with the ancient Nigerians and particularly with the Yorubas.Intradisciplinary and/or interdisciplinary implications: There is an existing ideology�amongst the Yorubas and other writers of Yoruba history that the original ancestors of�the Yorubas originated in ancient Egypt hence there was migration between Egypt and�Yorubaland. This researcher contends that even if there was migration between Egypt and�Nigeria, such migration did not take place during the predynastic and dynastic period as�speculated by some scholars. The subject is open for further research.

Bottom sediment in a marine system is formed from organic and inorganic particles which settle from water of aquatic media. The sediment compartment is the receptor of radionuclides and it indicates the impact of pollution. Radioactive materials like Ra and U are normal constituents of earths crust. The present study was done to estimate 226 Ra and U(Nat) from various locations in sediment off Mumbai coast. The levels of 226 Ra in sediments of Mumbai coast has been observed to be between 3.8 to 26.0 Bq/kg with a mean averaged value of 13.3 Bq/kg which is similar to the sediment at Bay of Bengal (13.9 to 25.9 Bq/kg), Indian Ocean (13.8 Bq/kg), Arabian Sea (16.9 to 31.7 Bq/kg), Egyptian Red sea coast (27.4 Bq/kg). Uranium content in sediment was found to be in the range of 16.3 to 56.3 Bq/kg with an averaged mean of 32.2 Bq/kg. It is observed that, uranium concentration is higher than radium concentration in sediment. This may be attributed to the relatively higher mobility of radium as compared to uranium in an aquatic environment

This paper presents an assessment of global sea level rise and the need to incorporate projections of rise into management plans for coastal adaptation. It also discusses the performance of a shoreline revetment; M. Ali Seawall, placed to protect the land against flooding and overtopping at coastal site, within Abu Qir Bay, East of Alexandria, Egypt along the Nile Delta coast. The assessment is conducted to examine the adequacy of the seawall under the current and progressive effects of climate change demonstrated by the anticipated sea level rise during this century. The Intergovernmental Panel on Climate Change (IPCC, 2007) predicts that the Mediterranean will rise 30 cm to 1 meter this century. Coastal zone management of the bay coastline is of utmost significance to the protection of the low agricultural land and the industrial complex located in the rear side of the seawall. Moreover this joint research work highlights the similarity of the nature of current and anticipated coastal zone problems, at several locations around the world, and required adaptation and protection measures. For example many barrier islands in the world such as that in the Atlantic and Gulf of Mexico coasts of the U.S., lowland and deltas such as in Italy and the Nile Delta, and many islands are also experiencing significant levels of erosion and flooding that are exacerbated by sea level rise. Global Climatic Changes: At a global scale, an example of the effects of accelerated climate changes was demonstrated. In recent years, the impacts of natural disasters are more and more severe on coastal lowland areas. With the threats of climate change, sea level rise storm surge, progressive storm and hurricane activities and potential subsidence, the reduction of natural disasters in coastal lowland areas receives increased attention. Yet many of their inhabitants are becoming increasingly vulnerable to flooding, and conversions of land to open ocean. These global changes were recently

Separated Children’s Migration in the Mediterranean Sea. An Ethnohistorical Perspective.

In the imaginary of Italian people, the Island of Lampedusa (Italy) has always been considered a paradise destination for summer holidays. The beauty of this small island at the heart of the Mediterranean Sea, far from big harbors and cities, with its rich biodiversity and unspoilt nature, has made it a national and international tourist attraction. However, in recent years its name become associated with scenes of tragic, desperate journeys made by people of different origins trying to reach Europe from North African coasts. This shift exists not only in Italian people’s perception, but also all over the world, as the news related to Lampedusa and other Italian areas affected by this phenomenon often finds a place in major foreign newspapers. Even if migrants have been reaching Italian (and, more generally, South European) coasts for the last 20 years, the date of 3 October 2013 constitutes a significant turning point, as the shipwreck that occurred on this day lead to numerous deaths and the Italian coast guard has been accused of an unsuccessful, belated rescue of the people on the vessel. In recent months the number of people, especially unaccompanied children, arriving by boat has increased. Most of them are fleeing from wars and persecution, and even if they are aware of the risk of crossing the Mediterranean Sea, they still decide to try. The paper presents the results of an ethnographic research conducted with unaccompanied and separated children in Sicily, in order to point out their oral memories.

A two years study was conducted to evaluate the solid waste management system in 143 villages representing the Egyptian rural areas. The study covers the legal responsibilities, service availability, environmental impacts, service providers, financial resources, private sector participation and the quality of collection services. According to UN reports more than 55% of Egyptian population lives in rural areas. A drastic change in the consumption pattern altered the quantity and quality of the generated solid wastes from these areas. Poor solid waste management systems are stigmata in most of the Egyptian rural areas. This causes several environmental and health problems. It has been found that solid waste collection services cover only 27% of the surveyed villages, while, the statistics show that 75% of the surveyed villages are formally covered. The service providers are local villager units, private contractors and civil community associations with a percentage share 71%, 24% and 5% respectively. The operated services among these sectors were 25%, 71% and 100% respectively. The share of private sector in solid waste management in rural areas is still very limited as a result of the poverty of these communities and the lack of recyclable materials in their solid waste. It has been found that direct throwing of solid waste on the banks of drains and canals as well as open dumping and uncontrolled burning of solid waste are the common practice in most of the Egyptian rural areas. The available land for landfill is not enough, pitiable designed, defectively constructed and unreliably operated. Although solid waste generated in rural areas has high organic contents, no composting plant was installed. Shortage in financial resources allocated for valorization of solid waste management in the Egyptian rural areas and lower collection fees are the main points of weakness which resulted in poor solid waste management systems. On the other hand, the farmer's participation

Red to Mediterranean Sea bioinvasion: natural drift through the Suez Canal, or anthropogenic transport?

Science.gov (United States)

Shefer, Sigal; Abelson, Avigdor; Mokady, Ofer; Geffen, Eli

2004-08-01

The biota of the eastern basin of the Mediterranean Sea has experienced dramatic changes in the last decades, in part as a result of the massive invasion of Red Sea species. The mechanism generally hypothesized for the 'Red-to-Med' invasion is that of natural dispersal through the Suez Canal. To date, however, this hypothesis has not been tested. This study examines the mode of invasion, using as a model the mussel Brachidontes pharaonis, an acclaimed 'Lessepsian migrant' that thrives along the eastern Mediterranean coast. Our findings reveal two distinct lineages of haplotypes, and five possible explanations are discussed for this observation. We show that the genetic exchange among the Mediterranean, Gulf of Suez and the northern Red Sea is sufficiently large to counteract the build up of sequential genetic structure. Nevertheless, these basins are rich in unique haplotypes of unknown origin. We propose that it is historic secondary contact, an ongoing anthropogenic transport or both processes, that participate in driving the population dynamics of B. pharaonis in the Mediterranean and northern Red Sea.

2018-04-01

The development of male genital tract by female gastropods, or imposex, can be caused by the tributyltin used in antifouling paints. A spatial survey of imposex in the gastropod Stramonita haemastoma was conducted across five Western Mediterranean and eleven North-Eastern Atlantic sites, in order to monitor the effectiveness of the tributyltin regulation imposed in the International Maritime Organisation. Imposex still occurs in eight out of eleven Mediterranean sites and in three out of five Atlantic sites. Extreme values of imposex incidence (I%) and degree (VDSI) were recorded in Tunisia, mainly in Bizerta channel (I% = 96.2%, VDSI = 0.96). However, the Relative Penis Length index (RPLI) was higher in Western Mediterranean sites where values varied between 0.56 in Algiers (Algeria) and 11.80 in Bouznika (Morocco). In the European sites, moderate to low imposex level and degree were recorded. All the affected sites were below the Ecotoxicological Assessment Criteria (EAC) derived for TBT.

Modeling the dispersal of Levantine Intermediate Water and its role in Mediterranean deep water formation

Science.gov (United States)

Wu, Peili; Haines, Keith

1996-03-01

This paper demonstrates the importance of Levantine Intermediate Water (LIW) in the deep water formation process in the Mediterranean using the modular ocean general circulation model at 0.25° resolution, 19 vertical levels, over the entire Mediterranean with an open Gibraltar strait. LIW formation is strongly prescribed in the Rhodes Gyre region by Haney [1971] relaxation, while in other regions, surface salinity relaxation is much reduced by applying the `mixed' thermohaline surface boundary conditions. Isopycnal diagnostics are used to trace water mass movements, and volume fluxes are monitored at straits. Low viscosity and diffusion are used to permit baroclinic eddies to play a role in water mass dispersal. The overall water budget is measured by an average flux at Gibraltar of 0.8 Sv, of which 0.7 Sv is exchanged with the eastern basin at Sicily. LIW (density around 28.95) spreads rapidly after formation throughout the entire Levantine due to baroclinic eddies. Toward the west, LIW accumulates in the northern and central Ionian, with some entering the Adriatic through Otranto and some mixing southward in eddies and exiting to the western Mediterranean through Sicily. LIW is converted to deep water in the south Adriatic at an average rate of 0.4 Sv. Water exchange through the Otranto strait appears to be buoyancy driven, with a strong bias to the end of winter (March-April), while at Sicily the exchange has a strong symmetric seasonal cycle, with maximum transport of 1.1 Sv in December indicating the effects of wind driving. LIW pathways in the west are complex and variable. In the Tyrrhenian, intermediate water becomes uniform on isopycnal surfaces due to eddy stirring. West of Sardinia, two LIW boundary currents are formed in the Balearic basin; one flows northward up the west coast of Sardinia and Corsica, and one westward along the northern African coast. The northward current is consistent with observations, while the westward current is intermittent for

Full Text Available The endemic Mediterranean zooxanthellate scleractinian reef-builder Cladocora caespitosa is among the organisms most affected by warming-related mass mortality events in the Mediterranean Sea. Corals are known to contain a diverse microbiota that plays a key role in their physiology and health. Here we report the first study that examines the microbiome and pathobiome associated with C. caespitosa in three different Mediterranean locations (i.e., Genova, Columbretes Islands, and Tabarca Island. The microbial communities associated with this species showed biogeographical differences, but shared a common core microbiome that probably plays a key role in the coral holobiont. The putatively pathogenic microbial assemblage (i.e., pathobiome of C. caespitosa also seemed to depend on geographic location and the human footprint. In locations near the coast and with higher human influence, the pathobiome was entirely constituted by Vibrio species, including the well-known coral pathogens Vibrio coralliilyticus and V. mediterranei. However, in the Columbretes Islands, located off the coast and the most pristine of the analyzed locations, no changes among microbial communities associated to healthy and necrosed samples were detected. Hence, our results provide new insights into the microbiome of the temperate corals and its role in coral health status, highlighting its dependence on the local environmental conditions and the human footprint.

Owis, Asmaa Ibrahim; El-Naggar, El-Motaz Bellah

2016-01-01

Background: Carob - Ceratonia siliqua L., commonly known as St John's-bread or locust bean, family Fabaceae - is one of the most useful native Mediterranean trees. There is no data about the chromatography methods performed by high performance liquid chromatography (HPLC) for determining polyphenols in Egyptian carob pods. Objective: To establish a sensitive and specific liquid chromatography–electrospray ionization (ESI)-tandem mass spectrometry (MSn) methodology for the identification of the major constituents in Egyptian carob extract. Materials and Methods: HPLC with diode array detector and ESI-mass spectrometry (MS) was developed for the identification and quantification of phenolic acids, flavonoid glycosides, and aglycones in the methanolic extract of Egyptian C. siliqua. The MS and MSn data together with HPLC retention time of phenolic components allowed structural characterization of these compounds. Peak integration of ions in the MS scans had been used in the quantification technique. Results: A total of 36 compounds were tentatively identified. Twenty-six compounds were identified in the negative mode corresponding to 85.4% of plant dry weight, while ten compounds were identified in the positive mode representing 16.1% of plant dry weight, with the prevalence of flavonoids (75.4% of plant dry weight) predominantly represented by two methylapigenin-O-pentoside isomers (20.9 and 13.7% of plant dry weight). Conclusion: The identification of various compounds present in carob pods opens a new door to an increased understanding of the different health benefits brought about by the consumption of carob and its products. SUMMARY This research proposed a good example for the rapid identification of major constituents in complex systems such as herbs using sensitive, accurate and specific method coupling HPLC with DAD and MS, which facilitate the clarification of phytochemical composition of herbal medicine for better understanding of their nature and

Coastal environment is a dynamic system in which numerous natural processes are continuously actuating and interacting among them. As a result, geomorphologic, physical and biological characteristics of coastal environments are constantly changing. Such dynamic balance is nowadays seriously threatened by the strong and increasing anthropic pressure that favors erosion processes, and the associated loss of environmental, ecologic and economic aspects. Sandy beaches are the most vulnerable environments in coastal areas. The aim of this work was to reconstruct the historical evolution of the Mediterranean coastline of Andalusia, Spain. The investigated area is about 500 km in length and includes the provinces of Cadiz, Malaga, Granada and Almeria. It is essentially composed by cliffed sectors with sand and gravel pocket beaches constituting independent morphological cells of different dimensions. This study was based on the analysis of aerial photos and satellite images covering a period of 55 years, between 1956 and 2011. Aerial photos were scanned and geo-referenced in order to solve scale and distortion problems. The shoreline was considered and mapped through the identification of the wet / dry sand limit which coincides with the line of maximum run-up; this indicator - representing the shoreline at the moment of the photo - is the most easily identifiable and representative one in microtidal coastal environments. Since shoreline position is linked to beach profile characteristics and to waves, tide and wind conditions at the moment of the photo, such parameters were taken into account in the calculation of shoreline position and changes. Specifically, retreat/accretion changes were reconstructed applying the DSAS method (Digital Shoreline Analysis System) proposed by the US Geological Survey. Significant beach accretion was observed at Playa La Mamola (Granada), with +1 m/y, because the construction of five breakwaters, and at Playa El Cantal (Almeria) and close

Cytochrome P4501A (CYP1A) monoxygenase, vitellogenin (Vtg) and Zona radiata proteins (Zrp) are frequently used as biomarkers of fish exposure to organic contaminants. In this work, swordfish liver sections obtained from the Mediterranean Sea, the South African coasts (South Atlantic and South Western Indian Oceans) and the Central North Pacific Ocean were immunostained with antisera against CYP1A, Zrp, and Vtg. CYP1A induction was found in hepatocytes, epithelium of the biliary ductus and the endothelium of large blood vessels of fish from the Mediterranean Sea and South African waters, but not from the Pacific Ocean. Zrp and Vtg were immunolocalized in hepatocytes of male swordfish from the Mediterranean Sea and from South African waters. Plasma Dot-Blot analysis, performed in Mediterranean and Pacific specimens, revealed the presence of Zrp and Vtg in males from Mediterranean but not from Pacific. These results confirm previous findings about the potential exposure of Mediterranean swordfish to endocrine, disrupting chemicals and raise questions concerning the possible presence of xenobiotic contaminants off the Southern coasts of South Africa in both the South Atlantic and South Western Indian Oceans

Long-term variations of man-made radionuclide concentrations in a bio-indicator Mytilus galloprovincialis from the French Mediterranean coast

Results from a 14-year monitoring (1984-1997) of man-made radionuclide (137Cs and 106Ru) levels in Mytilus galloprovincialis collected monthly on the French Mediterranean coast are presented. In this area sources of man-made radionuclides are on the one hand atmospheric fallout from both the past nuclear testings and the Chernobyl accident and on the other hand discharges from nuclear installations located on the Rhone River banks, especially those from the spent nuclear fuel reprocessing plant in Marcoule. Long-term variations of radionuclide concentrations in Mytilus demonstrated seasonal variations which are linked to the reproductive cycle of these organisms as well as to variations in land-based inputs of man-made radionuclides. A comparative study of these seasonal variations has been carried out with the aid of spectral analysis. Due to differences in released activities and discharge patterns, flow rates appear to govern mainly the 137Cs variations in the Rhone waters, whereas 106Ru variations are driven by the discharges. In the area under the influence of the Rhone outflow, 137Cs variations in mussels are characterized by seasonal variations which are themselves inversely correlated with variations of 137Cs concentrations in Rhone waters. This cyclic component seems to be closely linked to the mussel reproductive cycle. The possible influence of other parameters is discussed

Full Text Available During the summer of 2010, 31 species including fish, echinoderms, gastropods, crustaceans, cephalopods and sponges were sampled in the Bay of Villefranche on the French Mediterranean coast and screened for the presence of PLTX-group toxins using the haemolytic assay. Liquid chromatography tandem mass spectrometry (LC-MS/MS was used for confirmatory purposes and to determine the toxin profile. The mean toxin concentration in the whole flesh of all sampled marine organisms, determined using the lower- (LB and upper-bound (UB approach was 4.3 and 5.1 µg·kg−1, respectively, with less than 1% of the results exceeding the European Food Safety Authority (EFSA threshold of 30 µg·kg−1and the highest values being reported for sea urchins (107.6 and 108.0 µg·kg−1. Toxins accumulated almost exclusively in the digestive tube of the tested species, with the exception of octopus, in which there were detectable toxin amounts in the remaining tissues (RT. The mean toxin concentration in the RT of the sampled organisms (fishes, echinoderms and cephalopods was 0.7 and 1.7 µg·kg−1 (LB and UB, respectively, with a maximum value of 19.9 µg·kg−1 for octopus RT. The herbivorous and omnivorous organisms were the most contaminated species, indicating that diet influences the contamination process, and the LC-MS/MS revealed that ovatoxin-a was the only toxin detected.

Study of the radiation hazards for the building materials is interested in most international countries. Measurements of natural radioactivity was verified for some egyptian building materials to assess any possible radiological hazard to man by the use of such materials. The measurements for the level of natural radioactivity in the materials was determined by γ-ray spectrum using HP Ge detector. A track detector Cr-39 was used to measure the radon exhalation rate from these materials. The radon exhalation rates were found to vary from 2.83±0.86 to 41.57 ± 8.38 mBqm -2 h -1 for egyptian alabaster. The absorbed dose rate in air is lower than the international recommended value (55 n Gy h -1 ) for all test samples

2001-01-01

The concentrations of sulfur dioxide (SO 2 ), ammonia (NH 3 ) and particulate matter were measured for a 6-month period and the concentration of gas phase nitric acid (HNO 3 ) was measured for a 1-month period in the North-eastern Mediterranean atmosphere (Kuecuek Calticak, Antalya) using a 'filter pack' system that was developed and optimised in our laboratory. Among all the gas phase pollutants, HNO 3 had the lowest concentration (0.42 μg m -3 ) followed by ammonia. Most of the measured parameters showed variation in time depending on strengths of source regions and meteorological conditions. Nitric acid is found mostly in particulate form, but gas to particulate partitioning of SO 2 shows seasonal variation. Wind trajectory analyses indicate that the major contribution to the observed concentrations come mostly from Eastern Europe and Blacksea regions as well as the southern sector

A single adult specimen of Gonioinfradens giardi, a portunid crab known from the Red Sea, Gulf of Oman and Arabian Gulf, was recently collected off the southern Israeli coast, in the southeastern Mediterranean Sea. Morphological characters, as well as molecular analyses based on the mitochondrial barcoding gene cytochrome oxidase sub unit I (COI), support its distinction from the widely distributed G. paucidentata. Therefore, G. giardi is reinstated as a valid species, and withdrawn from its synonymy with G. paucidentata. Previous Mediterranean records of the latter species are misidentifications and should be referred to G. giardi. The species is described, illustrated, and differentiated from its cogener.

2015-05-01

The diversity and phylogeny of dinoflagellates belonging to the Gymnodiniales were studied during a 3-year period at several coastal stations along the Catalan coast (NW Mediterranean) by combining analyses of their morphological features with rDNA sequencing. This approach resulted in the detection of 59 different morphospecies, 13 of which were observed for the first time in the Mediterranean Sea. Fifteen of the detected species were HAB producers; four represented novel detections on the Catalan coast and two in the Mediterranean Sea. Partial rDNA sequences were obtained for 50 different morphospecies, including novel LSU rDNA sequences for 27 species, highlighting the current scarcity of molecular information for this group of dinoflagellates. The combination of morphology and genetics allowed the first determinations of the phylogenetic position of several genera, i.e., Torodinium and many Gyrodinium and Warnowiacean species. The results also suggested that among the specimens belonging to the genera Gymnodinium, Apicoporus, and Cochlodinium were those representing as yet undescribed species. Furthermore, the phylogenetic data suggested taxonomic incongruences for some species, i.e., Gyrodinium undulans and Gymnodinium agaricoides. Although a species complex related to G. spirale was detected, the partial LSU rDNA sequences lacked sufficient resolution to discriminate between various other Gyrodinium morphospecies.

The phosphate industry in Egypt includes three major activities, namely, mining and milling of phosphate rock, phosphate product manufacture, and phosphate product use. The production of fertilizers from natural phosphate ore can lead to the redistribution of uranium and other radionuclides in products, by-products and residues and hence, to severe environmental impacts and increased radiation exposures. In this study, the impact of loading cargoes of phosphate ore into ships at the Red Sea coast has been evaluated. The main objective was to assess the impact of phosphate loading activities near marine environment by determining the activity concentrations of '2 26 Ra ( 238 U) series, 232 Th series and 40 K in soil, sediment and seawater from El- Hamraween and Safaga Port where phosphate mine. The specific activities of 226 Ra ( 238 U) series, 232 Th series and 40 K (Bq/kg dry weight) were measured using gamma ray spectrometers based on hyper-pure germanium detectors. The specific activities showed high concentration level of 226 Ra. The concentration and distribution pattern of 226 Ra in sediment can be used to trace the radiological impact of the non-nuclear industries on the Red Sea coast. The absorbed dose (nGy/h) was also evaluated and can be used as a pre-operational baseline to estimate the possible radiological impacts due to mining, processing and future phosphate industrial activities. Because of the limited measures to control radiological hazards to individuals and the environment, normal occupational health and environmental protection measures were designed to protect against radiological hazards.

Full Text Available Data from 38 Argo profiling floats are used to describe the intermediate Mediterranean currents for the period October 2003–January 2010. These floats were programmed to execute 5-day cycles, to drift at a neutral parking depth of 350 m and measure temperature and salinity profiles from either 700 or 2000 m up to the surface. At the end of each cycle the floats remained at the sea surface for about 6 h, enough time to be localised and transmit the data to the Argos satellite system. The Argos positions were used to determine the float surface and intermediate displacements. At the surface, the float motion was approximated by a linear displacement and inertial motion. Intermediate velocities estimates were used to investigate the Mediterranean circulation at 350 m, to compute the pseudo-Eulerian statistics and to study the influence of bathymetry on the intermediate currents. Maximum speeds, as large as 33 cm/s, were found northeast of the Balearic Islands (western basin and in the Ierapetra eddy (eastern basin. Typical speeds in the main along-slope currents (Liguro-Provençal-Catalan, Algerian and Libyo-Egyptian Currents were ~20 cm/s. In the central and western part of Mediterranean basin, the pseudo-Eulerian statistics show typical intermediate circulation pathways which can be related to the motion of Levantine Intermediate Water. In general our results agree with the qualitative intermediate circulation schemes proposed in the literature, except in the southern Ionian where we found westward-flowing intermediate currents. Fluctuating currents appeared to be usually larger than the mean flow. Intermediate currents were found to be essentially parallel to the isobaths over most of the areas characterized by strong bathymetry gradients, in particular, in the vicinity of the continental slopes.

There are many critical industrial facilities such as energy production units and energy transmission lines along the southeast coast of Turkey. This region is also active on tourism, and agriculture and aquaculture production. There are active faults in the region, i.e. the Cyprus Fault, which extends along the Mediterranean basin in the east-west direction and connects to the Hellenic Arc. Both the Cyprus Fault and the Hellenic Arc are seismologically active and are capable of generating earthquakes with tsunamigenic potential. Even a small tsunami in the region could cause confusion as shown by the recent 21 July 2017 earthquake of Mw 6.6, which occurred in the Aegean Sea, between Bodrum, Turkey and Kos Island, Greece since region is not prepared for such an event. Moreover, the Mediterranean Sea is one of the most vulnerable regions against sea level rise due to global warming, according to the 5th Report of the Intergovernmental Panel on Climate Change. For these reasons, a marine hazard such as a tsunami can cause much worse damage than expected in the region (Kanoglu et al., Phil. Trans. R. Soc. A 373, 2015). Hence, tsunami hazard assessment is required for the region. In this study, we first characterize earthquakes which have potential to generate a tsunami in the Eastern Mediterranean. Such study is a prerequisite for regional tsunami mitigation studies. For fast and timely predictions, tsunami warning systems usually employ databases that store pre-computed tsunami propagation resulting from hypothetical earthquakes with pre-defined parameters. These pre-defined sources are called tsunami unit sources and they are linearly superposed to mimic a real event, since wave propagation is linear offshore. After investigating historical earthquakes along the Cyprus Fault and the Hellenic Arc, we identified tsunamigenic earthquakes in the Eastern Mediterranean and proposed tsunami unit sources for the region. We used the tsunami numerical model MOST (Titov et al

Lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials. Chemical analysis of cosmetics samples found in Egyptians tombs and the reconstitution of ancient recipes as reported by Greco-Roman authors have shown that two non-natural lead chlorides (laurionite Pb(OH)Cl and phosgenite Pb(2)Cl(2)CO(3)) were purposely synthesized and were used as fine powders in makeup and eye lotions. According to ancient Egyptian manuscripts, these were essential remedies for treating eye illness and skin ailments. This conclusion seems amazing because today we focus only on the well-recognized toxicity of lead salts. Here, using ultramicroelectrodes, we obtain new insights into the biochemical interactions between lead(II) ions and cells, which support the ancient medical use of sparingly soluble lead compounds. Submicromolar concentrations of Pb(2+) ions are shown to be sufficient for eliciting specific oxidative stress responses of keratinocytes. These consist essentially of an overproduction of nitrogen monoxide (NO degrees ). Owing to the biological role of NO degrees in stimulating nonspecific immunological defenses, one may argue that these lead compounds were deliberately manufactured and used in ancient Egyptian formulations to prevent and treat eye illnesses by promoting the action of immune cells.

Full Text Available The analysis of 255 bottom trawl samples obtained in annual experimental surveys (2007–2010 along the western Mediterranean shows the existence of five well-defined demersal assemblages that follow a depth distribution: (a upper shelf assemblages, including two assemblages differentiated by the type of substrate (sand-muddy and terrigenous muddy bottoms; (b a middle shelf assemblage; (c an upper slope assemblage; (d a middle slope assemblage. Faunally, they are dominated by fish (37% of 452 total species, followed by crustaceans (22%, molluscs (17%, echinoderms (9%, and other invertebrates (15%. The assemblages identified showed major alterations on the shelf and shelf edge and less pronounced ones on the upper and middle slope. The average diversity values were more or less high, evidencing the high species richness in the western Mediterranean. The identified assemblages may facilitate future multispecies fisheries management based on an ecosystem approach.

Conclusion: Our study concludes that mutations of NPHS2 gene are common among Egyptian children with SRNS. We support a model where ethnicity plays an important role in specific NPHS2 mutations, since a novel mutation was found in one patient in this study. Future study on a large number of Egyptian patients with SRNS is warranted to identify the actual genetic contribution of this gene in the development of SRNS in our population, which might help in patients' prognosis and management.

Full Text Available Background. Information about iodine intake is crucial for preventing thyroid diseases. Inadequate iodine intake can lead to thyroid diseases, including nontoxic nodular goiter (NNG. Objective. To estimate iodine intake and explore its correlation with thyroid diseases among Israeli adults living near the Mediterranean coast, where iodine-depleted desalinated water has become a major source of drinking water. Methods. Cross-sectional study of patients attending Barzilai Medical Center Ashkelon. Participants, who were classified as either NNG (n=17, hypothyroidism (n=14, or control (n=31, provided serum thyroglobulin (Tg and completed a semiquantitative iodine food frequency questionnaire. Results. Elevated serum Tg values (Tg > 60 ng/mL were significantly more prevalent in the NNG group than in the other groups (29% versus 7% and 0% for hypothyroidism and controls, resp., P<0.05. Mean estimated iodine intake was significantly lower in the NNG group (65±30 μg/d than in controls (115±60 μg/d (P<0.05 with intermediate intake in the hypothyroid group (73±38 μg/d. Conclusions. Elevated serum Tg values and low dietary iodine intake are associated with NNG among adult patients in Ashkelon District, Israel. Larger studies are needed in order to expand on these important initial findings.

For the purpose of estimating the radiological health and safety to the Egyptian population arises from the natural background involved with coastal areas, it is necessary to make a comprehensive study to investigate the natural radionuclides activities in this environmental ecology. The locations of such areas were chosen from those in which people spend some time (e.g. the Mediterranean and Red Sea beaches, Suez Canal in addition to the River Nile Ismailia Canal and Quaroun Lake). Water and soil samples were brought from these locations and subjected to intensive physical, chemical analysis and radiological investigations. The densities of the collected soil samples were found to fall in the region of clay densities (2.30 - 2.70 g/cm 3 ). The particle size distribution analysis, of these soil samples showed values ranging from 128 Μ m to 1303 Μ according to sample site. The collected samples are mainly silicates with variable amounts of the major cations; Ca + +, Mg + +, Na + , K + with some other trace elements. For the radiological investigations 238 U , 226 R a, 232 T h and 40 K activity concentrations were resolved by spectroscopy technique. The majority of samples examined in this work showed variable activities of the naturally occurring radionuclides with fairly low levels compared with literature values reported in other countries. The analysis and discussions of the obtained data are thoroughly performed with the use of equations to estimate the radiation doses

The composition, size distribution, and abundance of floating plastic debris in surface waters of the Mediterranean Sea were analyzed in relation to distance to land. We combined data from previously published reports with an intensive sampling in inshore waters of the Northwestern Mediterranean. The highest plastic concentrations were found in regions distant from from land as well as in the first kilometer adjacent to the coastline. In this nearshore water strip, plastic concentrations were significantly correlated with the nearness to a coastal human population, with local areas close to large human settlements showing hundreds of thousands of plastic pieces per km2. The ratio of plastic to plankton abundance reached particularly high values for the coastal surface waters. Polyethylene, polypropylene and polyamides were the predominant plastic polymers at all distances from coast (86 to 97% of total items), although the diversity of polymers was higher in the 1-km coastal water strip due to a higher frequency of polystyrene or polyacrylic fibers. The plastic size distributions showed a gradual increase in abundance toward small sizes indicating an efficient removal of small plastics from the surface. Nevertheless, the relative abundance of small fragments (plastic debris in areas closest to Mediterranean coast. The presence of a high concentration of plastic including tiny plastic items could have significant environmental, health and economic impacts.

A trial on the construction, maintenance and adaptation of the genetic sexing strain Vienna-8/Sr2 of the Mediterranean fruit fly, Ceratitis capitata (Wied.), has been done in the fruit fly laboratories of the Egyptian Atomic Energy Authority (EAEA) in the cooperation with the laboratories of International Atomic Energy Agency, Vienna. This trial was successful and this strain was maintained in the medfly laboratories of the EAEA for more than 10 generations up till now. Vienna-8/ Sr 2 is very stable strain and carries the dominant mutation called sergeant-2 (Sr 2 ) and could be used as a visible marker for the sterile male flies released in the field for controlling the Mediterranean fruit fly. This visible marker simplifies the discrimination between released sterile males and wild males caught in field monitoring traps. Males of this strain have three white stripes on the abdomen while wild males have only two stripes. The use of this genetic marker, as a replacement of the external dye marker, clearly has an immediate positive impact on the efficiency of Mediterranean fruit fly SIT programs (by using gamma radiation)

Verification of annual growth rings in Egyptian trees by C-14 method

International Nuclear Information System (INIS)

Belacy, N.; Abou El-Nour, F.; Jacoby, G.C.

1990-01-01

Annual growth rings in trees were thought to be due to sharp seasonal variations in the precipitation rates during the year. Accordingly temperature zone trees such as Egyptian trees were supposed to be away from this phenomenon. The temperature zones which are meant here are those of no sharp seasonal variations in the precipitation rates. The present study applied carbon-14 dating to prove that the growth rings in some Egyptian trees are annual. The method was based on the tropospheric measurements of C-14 during the period 1954-1981. C-14 exhibited a sharp peak resulting from the ever greater series of nuclear tests during 1963-1965. The presence of this peak for Egyptian trees proved that they form annual growth rings. (orig.)

Persistent chemicals and emerging pollutants are continuously detected in marine waters and biota. Out of these, polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCs) are significant contaminants with decades of presence in the marine environment. The Mediterranean Sea is an ecosystem directly affected by a variety of anthropogenic activities including industry, municipal, touristic, commercial and agricultural. The Mediterranean mussel (Mytilus galloprovincialis) is a filter feeder, which presents wide distribution. In this regard, the specific organism was used as a biological indicator for the monitoring and evaluation of pollution in the studied areas with focus on the mentioned chemical groups. Pristine Turkish sites with minimum effect from anthropogenic activities, in contrast with Greek sites which were subjected to heavy industrial and shipping activity, were selected. A gas chromatographic tandem mass spectrometric method (GC-MS/MS) was developed and validated to monitor 34 compounds (16 EPA priority PAHs and 18 OCs). Analyses of mussel samples in 2011 from sites with the limited anthropogenic pollution shores have shown the occurrence of 11 pollutants (6 PAHs, 5 OCs), while in the samples from sites with intensive activity and expected pollution, 12 PAHs and 6 OCs were detected. Biochemical and biological responses studied only in mussels samples from the sites with the highest contamination showed a situation that was under strong seasonal influence. The intensity of the response was also influenced by deployment duration. Noteworthy correlations were detected among biochemical/biological effects and between mussel body burden and these effects. Continuous monitoring of priority pollutants of East Mediterranean Sea is vital both for ecological and human risk assessment purposes. Copyright © 2014 Elsevier Ltd. All rights reserved.

Egypt, located on the isthmus of Africa, is an ideal region to study historical population dynamics due to its geographic location and documented interactions with ancient civilizations in Africa, Asia and Europe. Particularly, in the first millennium BCE Egypt endured foreign domination leading to growing numbers of foreigners living within its borders possibly contributing genetically to the local population. Here we present 90 mitochondrial genomes as well as genome-wide data sets from three individuals obtained from Egyptian mummies. The samples recovered from Middle Egypt span around 1,300 years of ancient Egyptian history from the New Kingdom to the Roman Period. Our analyses reveal that ancient Egyptians shared more ancestry with Near Easterners than present-day Egyptians, who received additional sub-Saharan admixture in more recent times. This analysis establishes ancient Egyptian mummies as a genetic source to study ancient human history and offers the perspective of deciphering Egypt's past at a genome-wide level. PMID:28556824

Tsunami deposits in the Balearic Islands (western Mediterranean) and implications for hazard assessment.

Significant earthquakes occur along the north Algerian and Carboneras faults (e.g. Djijelli 1865, Zemmouri 2003) and they may generate tsunamis in the western Mediterranean Basin and Alboran Sea, where tsunami hazard are poorly documented. The coast of southern Spain and Balearic Islands are densely populated, with touristic areas and important harbors. The 2003 event generated a small tsunami in the Balearic Islands (ships were moved by oscillations during more than 2 hours in some harbors). Reicherter et al. (2009) found evidences of two past tsunamis in lagoon of the Cabo de Gata (near Almeria), which they ascribed to the 1522 earthquake and an earlier event (islands revealed few evidences of past tsunamis. Thin sandy layers with marine bioclasts, possibly deposited by tsunamis, were found in three areas at altitudes always lower than 2m. Boulder clusters were found along the southern coast of Mallorca, but they could have been deposited by storms as well. These investigations are realized in the framework of the MAREMOTI project, funded by the French ANR and leaded by the CEA - DASE. Reicherter, K., Becker-Heidmann, P., 2009.

Hegemony for Beginners: Egyptian Activity in the Southern Levant during the Second Half of the Fourth Millennium B.C

Directory of Open Access Journals (Sweden)

Branislav Anđelković

2016-03-01

Full Text Available After a modest start in the mid-20th century, thousands of Protodynastic Egyptian objects have been unearthed and identified as such in the Southern Levant, including serekh-signs of several Dynasty 0 (Narmer, "Double Falcon", Ny-Hor, IryHor, Ka, and 1st Dynasty (Hor Aha pharaohs. The explanatory models presented so far fail to integrate the totality of the archaeologically manifested parameters, especially considering the impact of the last fifteen years of finds and their contextual and other analysis, into the proper semiotic matrix. The conundrum of Egyptian activity in the Southern Levant displays, at the same time, features of a small-scale trading partner, a colonizer, and a suzerain. Egyptian pottery of local origin provides an indication of a south-north flow of the Egyptian daily-life repertoire of pottery types, or rather their contents, between the Egyptian-related sites, that clearly demonstrates an Egyptian distribution system operating on an intra-regional level in the Early Bronze IB Southern Levant. The ‘Egyptian phenomenon’ is far from being unique since reestablishment of a similar geopolitical pattern, only on a considerably greater scale, can be recognized during the New Kingdom – the Egyptian province in Asia.

First record of the Central Indo-Pacific reef coral Oulastrea crispata in the Mediterranean Sea

Directory of Open Access Journals (Sweden)

B. W. HOEKSEMA

2014-03-01

Full Text Available A live colony of a non-indigenous zooxanthellate scleractinian coral was found in shallow water at the west coast of Corsica, western Mediterranean. Its diameter of 6 cm suggests that it has already survived for some years. It was identified as Oulastrea crispata, a species native on near-shore coral reefs in the central Indo-Pacific with a high tolerance for low water temperatures at high latitudes. Based on its morphology it can be distinguished from other zooxanthellate colonial scleractinians in the Mediterranean. O. crispata has a reputation of being a successful colonizer because it is able to settle on a wide variety of substrata and because it utilizes various reproductive strategies as simultaneous hermaphrodite and producer of asexually derived planulae. Owing to its original distribution range in temperate and subtropical waters, it is likely that it will be able to meet a suitable temperature regime in the Mediterranean for further range expansion.

Dental affinities of the C-group inhabitants of Hierakonpolis, Egypt: Nubian, Egyptian, or both?

Science.gov (United States)

Irish, J D; Friedman, R

2010-04-01

By c. 2050 BC a small community of C-Group Nubians was present deep within Egyptian territory at the city of Hierakonpolis. Their descendants stayed for the next 400 years. Today, the site of Hierakonpolis, 113 km north of Aswan, is known for its Egyptian deposits; however, it also contains a C-Group cemetery, which documents the northernmost occurrence of this culture. Sixty skeletons were excavated. Tombs feature Nubian architecture and goods, including leather garments, although the use of Egyptian mortuary practices and artifacts increased through time. Dates range from the early 11th Dynasty into the Second Intermediate period. During this time the Egyptian empire occupied Lower Nubia, and their state ideology vilified Nubians. Yet, at least in death, the C-Group inhabitants of Hierakonpolis proudly displayed their cultural heritage. Beyond discerning the reason(s) for their presence at the site (e.g., mercenaries, leather-workers, entertainers?), the focus of this report is to estimate their biological affinity. Were they akin to other Nubians, Egyptians, or both? And, was increasing 'Egyptianization' evident in the mortuary ritual accompanied by concomitant genetic influence? To address these queries, up to 36 dental morphological traits in the recovered individuals were compared to those in 26 regional comparative samples. The most influential traits were identified and phenetic affinities were calculated using the mean measure of divergence and other multivariate analyses. Assuming phenetic similarity provides an estimate of genetic relatedness, these affinities suggest the individuals comprising the C-Group sample were, and remained Nubian during their tenure at Hierakonpolis.

Environmental drivers of distribution and reef development of the Mediterranean coral Cladocora caespitosa

Science.gov (United States)

Chefaoui, Rosa M.; Casado-Amezúa, Pilar; Templado, José

2017-12-01

Cladocora caespitosa is the only Mediterranean scleractinian similar to tropical reef-building corals. While this species is part of the recent fossil history of the Mediterranean Sea, it is currently considered endangered due to its decline during the last decades. Environmental factors affecting the distribution and persistence of extensive bank reefs of this endemic species across its whole geographic range are poorly understood. In this study, we examined the environmental response of C. caespitosa and its main types of assemblages using ecological niche modeling and ordination analysis. We also predicted other suitable areas for the occurrence of the species and assessed the conservation effectiveness of Mediterranean marine protected areas (MPAs) for this coral. We found that phosphate concentration and wave height were factors affecting both the occurrence of this versatile species and the distribution of its extensive bioconstructions in the Mediterranean Sea. A set of factors (diffuse attenuation coefficient, calcite and nitrate concentrations, mean wave height, sea surface temperature, and shape of the coast) likely act as environmental barriers preventing the species from expansion to the Atlantic Ocean and the Black Sea. Uncertainties in our large-scale statistical results and departures from previous physiological and ecological studies are also discussed under an integrative perspective. This study reveals that Mediterranean MPAs encompass eight of the ten banks and 16 of the 21 beds of C. caespitosa. Preservation of water clarity by avoiding phosphate discharges may improve the protection of this emblematic species.

In recent decades the increased demand for the recreational use of beaches has resulted in the uptake of studies on the morphodynamic processes which are acting on beaches. This knowledge is fundamental for appropriate coastal erosion management, suitable tourist use of littoral and for the design and shape of human construction. The Mediterranean sectors of Moroccan littoral investigated in this study, Ksar Rimal and Cabo Negro beaches, are respectively located north and south of Cabo Negro promontory and, over recent years, have been subject to increasing tourist activity. This has consisted mainly of the construction of two tourist ports (Marina Smir and Kabila), residential developments, hotels and a motorway which runs parallel to the coast, affecting the dune ridges and two lagoons which are of great ecological interest. In detail, the dunes located in the backshore at Ksar Rimal beach, are nowadays occupied by summer houses threaten by coastal retreat. A wide, partially urbanized, backshore is observed at Cabo Negro beach. With the intention of characterize the morphodynamic and seasonal behavior and the response of the studied beaches to storm impact, a beach monitoring program was carried out in the period 2006-2008, with special attention to the February-March 2008 stormy period. On analyzing the information obtained, it was possible to characterize the morphology and sedimentology of the studied beaches, and to calculate beach volumetric variations. Ksar Rimal is an open, exposed beach characterized by an intermediate slope (tan β = 0.10) with medium-coarse sands. The beach showed a reflective beach state characterized by plunging breakers. Small morphological seasonal changes were observed, most important morphological and volumetric variations (about 20 m3/m) taking place after winter storms which usually gave rise to a more dissipative beach profile (tan β = 0.05) characterized by spilling breakers. Beach recovery was quite rapid, usually lasting 2

Extensive sampling of the Tsampika marly diatomites reveals the presence of at least three very important fish species, Bregmaceros sp., Sygnathus acus and Spratteloides sp.. Previous records of Bregmaceros sp. in the Mediterranean have suggested that this characteristic Pliocene warm-water circumglobal pelagic fish disappeared from the Mediterranean basin due to the climatic deterioration, after the Gelasian age1,2,3,4. The Tsampika fish-bearing deposits, mainly marly diatomites, are younger than 268 Ka, based on the occurrence of Emiliania huxleyi. Consequently, this is so far the youngest record of Bregmaceros sp. in the Mediterranean, suggesting that typical Pliocene fish may have found refuge in selected localities, such as Tsampika Bay, at least until the Ionian. Evidence for its presence in the Mediterranean basin today is ambiguous. Isolated records of Bregmaceros atlanticus place it in the Sicily Strait5, and off the Israeli and south Turkish coasts6. Although it appears more likely that Bregmaceros atlanticus has been introduced to the modern Mediterranean from the Red Sea, through the Suez Canal, the possibility that it is part of a small population native to the Mediterranean can not be excluded based on present-day data6. Indeed the late Pleistocene Mediterranean fish record is obsolete, due to the lack of appropriate sampling on this subject. Furthermore, the majority of Pleistocene Bregmaceros samples pertain to otoliths, which cannot be unambiguously identified on the species level. As a result, the present findings pose the considerable possibility that the Pleistocene Bregmaceros records belong to two species, B. albyi, the well known post-Messinian Mediterranean fish, and B. atlanticus, which may have invaded the Mediterranean Sea from Gibraltar along with several other warm-water taxa during recurring interglacial periods. The specific identification of the Tsampika fish will undoubtedly shed light to this possibility, and enhance our knowledge

Paleoradiology: advanced CT in the evaluation of nine Egyptian mummies.

2002-01-01

Axial thin-collimation state-of-the-art spiral computed tomography (CT) was combined with sagittal and coronal reformatting, three-dimensional (3D) reconstruction, and virtual "fly-through" techniques to nondestructively study nine Egyptian mummies. These techniques provided important paleopathologic and historical information about mummification techniques, depicted anatomy in the most informative imaging plane, illustrated the soft-tissue preservation and physical appearance of mummies in superb detail, and generated an intriguing virtual tour through hollow mummified remains without harming the specimens themselves. Images generated with these methods can help archaeologists and Egyptologists understand these fascinating members of mankind and can serve as adjunct visual aids for laypersons who are interested in mummies. CT has emerged as the imaging modality of choice for the examination of Egyptian mummies due to its noninvasive cross-sectional nature and inherently superior contrast and spatial resolution. As multi-detector row CT and postprocessing tools evolve, the capabilities and applications of CT will continue to proliferate, attesting to the expanded versatility and utility of CT as a noninvasive research tool in the multidisciplinary study of Egyptian mummies.

Full Text Available While views may differ on the factors that made the 2011 Egyptian revolution possible, the role of mass media will remain undisputable. The Internet-based social networks caught the Mubarak regime by surprise, and the popular disillusionment with the ‘national’ media led the public to turn to private newspapers and satellite channels for keeping pace with the events. This paper examines the role of specific media during the 18 days of the 2011 Egyptian revolution – from 25 January to 11 February, 2011 – which we have divided into four parts. It discusses how these media contributed to the unfolding of events, conceptualized the protests and the demands of the public, and presented the actors that participated in or opposed the revolution. These points are addressed by discussing the content of the Facebook pages of the Sixth of April Movement and We Are All Khalid Said, as well as that of a private Egyptian newspaper, al-Shuruq, and the state-run newspaper al-Ahram.

Determinants of the Egyptian labour migration.

Kandil, M; Metwally, M

1992-03-01

The objective is to summarize the pattern of Egyptian migration to Arab oil-producing countries (AOPC), to review some factors that are important determinants of labor movement based on theory, and to empirically model the migration rate to AOPC and to Saudi Arabia. Factors are differentiated as to their relative importance. Push factors are the low wages, high inflation rate, and high population density in Egypt; pull factors are higher wages. It is predicted that an increase in income from destination countries has a significant positive impact on the migration rate. An increase in population density stimulates migration. An increase in inflation acts to increase out-migration with a 2-year lag, which accommodates departure preparation. Egypt's experience with labor migration is described for the pre-oil boom, and the post-oil boom. Several estimates of labor migration are given. Government policy toward migration is positive. Theory postulates migration to be determined by differences in the availability of labor, labor rewards between destination and origin, and the cost of migration. In the empirical model, push factors are population density, the current inflation rate, and the ratio of income/capita in AOPC to Egypt. The results indicate that the ratio of income/capita had a strong pull impact and population density had a strong push impact. The inflation rate has a positive impact with a lag estimated at 2 years. Prior to the Camp David Accord, there was a significant decrease in the number of Egyptian migrants due to political tension. The findings support the classical theory of factor mobility. The consequences of migration on the Egyptian economy have been adverse. Future models should disaggregate data because chronic shortages exist in some parts of the labor market. Manpower needs assessment would be helpful for policy makers.

Zoogeographical patterns of flatfish (Pleuronectiformes parasites in the Northeast Atlantic and the importance of the Portuguese coast as a transitional area

Full Text Available Parasites are recognised as an excellent source of information on the distribution of their hosts. Here, the macroparasite fauna of 20 species of Pleuronectiformes belonging to five different families and inhabiting the Portuguese coast was investigated and compared with that known in four other areas (the North Sea, north Northeast Atlantic, Mediterranean Sea and Northwest African coast in order to determine (1 their zoogeographical pattern and (2 the role of the Portuguese coast as an intermediate biogeographic province. Macroparasites infecting Pleuronectiformes sampled along the Portuguese coast were collected using standard parasitological techniques, whereas data on those in the other four areas were obtained from the literature, rendering a total of 73 macroparasite species. Both sets of data were then compiled in a presence/absence matrix. Hosts and macroparasites were placed into zoogeographical categories according to their known distribution, and patterns were evaluated using multidimensional scaling and cluster analysis. The zoogeography of hosts and parasites was not entirely concordant, although that of endoparasites was generally consistent with the patterns for marine free-living species. On the other hand, only specific ectoparasites truly mirrored the distribution of their hosts. These differences reflect the importance of host ecology and dispersal and environmental factors on the patterns revealed. The Portuguese coast seems to play a significant role in the distribution of Pleuronectiformes’ parasites along the Northeast Atlantic and Mediterranean Sea, due to its transitional character and to the sympatric occurrence of related hosts, both promoting the acquisition of new parasite species or the maintenance of historical host-parasite relationships.

A new cold-water coral (CWC) province has been identified in the Mediterranean Sea in the Capo Spartivento canyon system offshore the southern coast of Sardinia. The 'Sardinia cold-water coral province' is characterized in the Nora canyon by a spectacular coral growth dominated by the branching scleractinian Madrepora oculata at a depth of 380-460 m. The general biohermal frame is strengthened by the common occurrence of the solitary scleractinian Desmophyllum dianthus and the occasional presence of Lophelia pertusa. As documented by Remotely Operated Vehicle survey, this area is a hotspot of megafaunal diversity hosting among other also live specimens of the deep oyster Neopycnodonte zibrowii. The new coral province is located between the central Mediterranean CWC provinces (Bari Canyon, Santa Maria di Leuca, South Malta) and the western and northern ones (Melilla, Catalan-Provençal-Ligurian canyons). As for all the best developed CWC situations in the present Mediterranean Sea, the new Sardinian province is clearly influenced by Levantine Intermediate Water which appears to be a main driver for CWC distribution and viability in this basin.

Building construction in accordance with the climate in oases of the Egyptian desert is discussed. Climatic conditions and the resulting consequences for structural physics play a major role. With the aid of Olgay's comfort diagram, requirements to be made on buildings in various oases are derived from the climatic data of these oases. To optimize the indoor climate, shading, heat storage and ventilation measures are discussed, and suggestions are made on how to make use of this knowledge in consideration of traditional Egyptian architecture.

The Restoration and Conservation of Egyptian Alabaster Vessels from the Early ERA in Atfiyah Museum Store - Helwan - Egypt

Egypt is considered one of the most countries which contain a lot of cultural heritage; the Ancient Egyptian used a lot of stones for his life like: limestone, sandstone, granite and Egyptian Alabaster. The Egyptian Alabaster is used for his daily and eternal life, he made a lot of funerary furniture from this stone like: vessels, statues, Architectural elements in the temples, tombs and canopic jars to preserve his viscera from decomposition like: stomach, liver … etc in the mummification process. Egyptian Alabaster is a sedimentary rock especially chemical- origin sedimentary rocks, it deposits inside caves and around springs which consists of calcium carbonates (CaCO3), they are very fragile "hardness = 3 in Mohs hardness scale". The Egyptian Alabaster vessels expose to a lot of deterioration factors in the burial and exposure environment after excavation. The study case vessels are made of Egyptian alabaster stone and belong to the early era (First and second Egyptian dynasties) in Atfiyah museum store, these vessels exposed to a lot of deterioration factors in the burial and exposure environment like: soil pressure, air temperature variety, relative humidity and salts. The vessels are conserved at the restoration laboratory in Atfiyah museum store by a lot of restoration and conservation processes like: cleaning - consolidation - assembling process for the separated parts and completion for the lost parts.

Caesium-137 in Marine Sediments of the Eastern Mediterranean from the Pre-Chernobyl Age to the Present

International Nuclear Information System (INIS)

Florou, Heleny; Evangeliou, Nikolaos; Kritidis, Panagiotis

2011-01-01

Caesium-137 (half-life 30.2 years) was first introduced into the marine environment as a result of the atmospheric nuclear weapon testing during 1953-1963. The second and largest contamination was the fallout after the Chernobyl accident in April 1986. Since 1986 the radiological status of the Mediterranean has been changed. During 1986 the average deposition of 137 Cs from the fallout in the Aegean Sea has been estimated to be approximately 4 kBq m -2 , whereas the respective value for the Ionian Sea (the area of 24,300 km 2 along the coasts) was 2.5 kBq m -2 . The total caesium ( 137 Cs + 134 Cs) input from Chernobyl fallout has been estimated to be 2400 TBq for the Black Sea, 820 TBq for the Aegean Sea and 600 TBq in the Ionian Sea (60 TBq in the zone of 50 km across the coasts). Although, the residence time of 137 Cs in seawater is long, it has been observed that 137 Cs has reached the bottom sediments, as the remaining period is long enough if compared to the estimated sinking time for the Mediterranean environment. The Mediterranean Sea is a semi-enclosed marine area, exchanging water, salt, heat and other physicochemical properties through the strait of Gibraltar with the Atlantic Ocean.The basin is characterized by low precipitation and high evaporation, which causes accumulation of contaminants in seawater and sediment. Taking into account the topography,one could note the importance of the eastern part of the Mediterranean,since it comprises a continuous source of interregional input (Black Sea). However,the motive of determining 137 Cs in the Greek marine territory was basic research (pre-Chernobyl age) and monitoring reasons (after Chernobyl accident). Several Greek marine systems have been examined throughout these years and the results are evaluated in the present study.

Ecosystem Alterations and Species Range Shifts: An Atlantic-Mediterranean Cephalaspidean Gastropod in an Inland Egyptian Lake

Science.gov (United States)

Malaquias, Manuel António E.

2016-01-01

The eastern Atlantic and Mediterranean marine Cephalaspidea gastropod Haminoea orbignyana was collected from Lake Qarun (Fayoum, Egypt), a landlocked lake that has undergone a shift from freshwater to estuarine conditions in the past 100 years. Species identity was confirmed by both morphological (anatomical dissection and scanning electron microscopy) and molecular methods (COI gene phylogeny). Observations suggested a robust population of H. orbignyana in the lake with a density of ca. 64 individuals/m2 and ca. 105 egg masses/m2 during surveys conducted in the summer of 2013. The vast majority of snails and egg masses were found under rocks. Observations of egg masses in the lab showed a gradual change from whitish to yellow-green as the eggs matured and the release of veliger larvae alone after about a week. Although adult cephalaspideans readily consumed filamentous red and green algae, and cyanobacteria, laboratory trials showed that they consumed significantly more of the red alga Ceramium sp., than of the green alga Cladophora glomerata, with consumption of Oscillatoria margaritifera being similar to those on the two algae. When grown on these resources for 16 days, H. orbignyana maintained their mass on the rhodophyte and cyanobacterium, but not in starvation controls. No cephalaspideans grew over the course of this experiment. Lake Qarun has been periodically restocked with Mediterranean fishes and prawns since the 1920s to maintain local fisheries, which represents a possible route of colonization for H. orbignyana. Yet, based on literature records, it seems more likely that invasion of the lake by this gastropod species has occurred only within the last 20 years. As human activities redistribute species through direct and indirect means, the structure of the community of this inland lake has become unpredictable and the long-term effects of these recent introductions are unknown.

This study aims to describe the patterns of soft bottom macrozoobenthic richness along French coasts. It is based on a collaborative database developed by the "Réseau des Stations et Observatoires Marins" (RESOMAR). We investigated patterns of species richness in sublittoral soft bottom habitats (EUNIS level 3) at two different spatial scales: 1) seaboards: English Channel, Bay of Biscay and Mediterranean Sea and 2) 0.5° latitudinal and longitudinal grid. Total observed richness, rarefaction curves and three incidence-based richness estimators (Chao2, ICE and Jacknife1) were used to compare soft bottom habitats species richness in each seaboard. Overall, the Mediterranean Sea has the highest richness and despite higher sampling effort, the English Channel hosts the lowest number of species. The distribution of species occurrence within and between seaboards was assessed for each major phylum using constrained rarefaction curves. The Mediterranean Sea hosts the highest number of exclusive species. In pairwise comparisons, it also shares a lower proportion of taxa with the Bay of Biscay (34.1%) or the English Channel (27.6%) than that shared between these two seaboards (49.7%). Latitudinal species richness patterns along the Atlantic and English Channel coasts were investigated for each major phylum using partial LOESS regression controlling for sampling effort. This showed the existence of a bell-shaped latitudinal pattern, highlighting Brittany as a hotspot for macrobenthic richness at the confluence of two biogeographic provinces.

Genetic Drift. The ancient Egyptian dwarfs of the Walters Art Museum.

Kozma, Chahira

2010-10-01

The ancient Egyptians left an impressive artistic legacy documenting many aspects of their society including the existence of dwarfs as highly valued members. In previous publications in the Journal, I discussed dwarfs and skeletal dysplasia in ancient Egypt. In this study, I examined the ancient Egyptian representations of dwarfs of the Walters Art Museum in Baltimore, Maryland. One of the highlights of the collection is a group of five ivory figurines from Predynastic Times (pre 3500-3100 BCE) depicting a couple, a man with a child, and two females. Representations from other periods include ordinary as well as dwarf deities. The dwarf gods, Bes and Ptah, are frequently depicted holding or biting snakes or standing on crocodiles symbolizing their ability to ward off dangers. A couple of statuettes from the Greco-Roman Period that, in contrast to earlier Egyptian Periods, depict harsh physical anomalies, twisted bodies, and facial pain. The artistic impression can be interpreted as either tragic or humorous. The grotesque depiction of dwarfs during the Greco-Roman Period in ancient Egypt is believed to be due to a greater infusion of Hellenistic influence. This study provides a microcosm of the legacy of dwarfs in ancient Egypt and supports the premise that dwarfs were accepted and integrated in the ancient Egyptian society, and with a few exceptions, their disorder was not depicted as a physical handicap.

Modelling the background aerosol climatologies (1989-2010) for the Mediterranean basin

Science.gov (United States)

Jimenez-Guerrero, Pedro; Jerez, Sonia

2014-05-01

Aerosol levels and composition are influenced by multiple atmospheric physico-chemical processes that can affect them from its release point (as primary aerosol), or via gas-to-particle conversion processes that give rise to secondary aerosols. The contribution of the various aerosol sources, the role of long-range transport and the contribution of primary and secondary particulate matter to the ambient aerosol concentrations over Europe are not well known (Kulmala et al., 2009). Focusing on the Mediterranean, Querol et al. (2009) point out that there is a lack of studies on the variability of particulate matter (PM) along the Mediterranean basin, necessary for understanding the special features that differentiate aerosol processes between the western, eastern and central Mediterranean basins. In this perspective, modelling systems based on state-of-science chemistry transport models (CTMs) are fundamental elements to investigate the transport and chemistry of pollutants behaviour at different scales and to assess the impact of emissions in aerosol levels and composition. Therefore, this study aims to summarise the results on the levels and chemical composition of aerosols along the Mediterranean basin, highlighting the marked gradient between the western-central-eastern coasts. Special attention is paid to the analysis of the seasonality of PM composition and levels. For this purpose, the regional modelling system WRF-CHIMERE-EMEP has been implemented for conducting a full transient simulation for the ERA-Interim period (1989-2010) using year-to-year changing EMEP emissions. The domain of study covers Europe with a horizontal resolution of 25 km and a vertical resolution of 23 layers in the troposphere; however the analysis focuses on the Mediterranean area. The PM levels and composition are compared to the measured values reported by the EMEP network, showing a good agreement with observations for both western and eastern Mediterranean.

Compatibility of global environmental assessment methods of buildings with an Egyptian energy code

Amal Kamal Mohamed Shamseldin

2017-04-01

Full Text Available Several environmental assessment methods of buildings had emerged over the world to set environmental classifications for buildings, such as the American method “Leadership in Energy and Environmental Design” (LEED the most widespread one. Several countries decided to put their own assessment methods to catch up with the previous orientation, such as Egypt. The main goal of putting the Egyptian method was to impose the voluntary local energy efficiency codes. Through a local survey, it was clearly noted that many of the construction makers in Egypt do not even know the local method, and whom are interested in the environmental assessment of buildings seek to apply LEED rather than anything else. Therefore, several questions appear about the American method compatibility with the Egyptian energy codes – that contain the most exact characteristics and requirements and give the outmost credible energy efficiency results for buildings in Egypt-, and the possibility of finding another global method that gives closer results to those of the Egyptian codes, especially with the great variety of energy efficiency measurement approaches used among the different assessment methods. So, the researcher is trying to find the compatibility of using non-local assessment methods with the local energy efficiency codes. Thus, if the results are not compatible, the Egyptian government should take several steps to increase the local building sector awareness of the Egyptian method to benefit these codes, and it should begin to enforce it within the building permits after a proper guidance and feedback.

The European sardine, Sardina pilchardus, exhibits a complex population structure, which has produced conflicting results in previous genetic studies. Despite its importance in the fisheries industry, stock delineation for management and conservation purposes is still a matter of debate throughout the distribution range of the species. This study examines whether otolith shapes are more efficient than genetic markers to detect population structure in pelagic species with large population sizes. Sardines were analyzed from 15 sampling localities in the Northeast Atlantic and Mediterranean Sea covering almost the whole distribution range of the species. A combination of otolith shape indices and elliptic Fourier descriptors was investigated by multivariate statistical procedures. Within the studied area, three distinct groups were identified with an overall correct classification of 77%. Group A: northern Mediterranean Sea and Gulf of Gabès; group B: Atlantic Morocco-south Alboran-Algero-provençal coasts; and group C: European Atlantic coast. The Almeria-Oran front and the Gibraltar strait are not an efficient barrier for sardine population separation as there seems to be exchanges between populations of the south-western Mediterranean Sea and those of the Moroccan Atlantic Ocean coast or Gulf of Cadiz. The results are discussed in relation to environmental conditions, oceanographic features, and physical barriers to dispersal in the study area, and compared with those obtained by previous genetic, morphometric, and meristic data. For pelagic species with high gene flow, present results highlighted the need to take into account the identification of phenotypic stocks to ensure sustainable fishery benefits and efficient conservation as they may have unique demographic properties and responses to exploitation.

Nutrient and Phytoplankton Analysis of a Mediterranean Coastal Area

Sebastiá, M. T.; Rodilla, M.

2013-01-01

Identifying and quantifying the key anthropogenic nutrient input sources are essential to adopting management measures that can target input for maximum effect in controlling the phytoplankton biomass. In this study, three systems characterized by distinctive main nutrient sources were sampled along a Mediterranean coast transect. These sources were groundwater discharge in the Ahuir area, the Serpis river discharge in the Venecia area, and a submarine wastewater outfall 1,900 m from the coast. The study area includes factors considered important in determining a coastal area as a sensitive area: it has significant nutrient sources, tourism is a major source of income in the region, and it includes an area of high water residence time (Venecia area) which is affected by the harbor facilities and by wastewater discharges. We found that in the Ahuir and the submarine wastewater outfall areas, the effects of freshwater inputs were reduced because of a greater water exchange with the oligotrophic Mediterranean waters. On the other hand, in the Venecia area, the highest levels of nutrient concentration and phytoplankton biomass were attributed to the greatest water residence time. In this enclosed area, harmful dinoflagellates were detected ( Alexandrium sp. and Dinophysis caudata). If the planned enlargement of the Gandia Harbor proceeds, it may increase the vulnerability of this system and provide the proper conditions of confinement for the dinoflagellate blooms' development. Management measures should first target phosphorus inputs as this is the most potential-limiting nutrient in the Venecia area and comes from a point source that is easier to control. Finally, we recommend that harbor environmental management plans include regular monitoring of water quality in adjacent waters to identify adverse phytoplankton community changes.

More than a Facebook revolution: Social movements and social media in the Egyptian Arab Spring

Luis Fernando Barón

2015-06-01

Full Text Available Public opinion leaders and activists characterized the Egyptian “Arab Spring” of January 2011 as a “Facebook Revolution”. They highlight the intrinsic power of social media as an influencing factor for social change. Undeniably, social media played important roles in that revolution process. However, these roles cannot be disconnected from the socio-political contexts. This paper discusses the use of social media, particularly of Facebook, by the April 6th Youth Movement (A6YM, a decisive actor of the Egyptian protests. It is based on the analysis of two Egyptian newspapers and one American newspaper, between 2008 and 2011. We propose that a social media provided alternative mechanisms for political expression and organization, b social media contributed to the genesis and consolidation of the A6YM and to the establishment of youth political identities, and c the combination of “bits and streets” amplified not just the movement’s mobilization but the degree of opposition experienced by the Egyptian regime.

The distribution of microplastics (MPs) was investigated in the sediments of five sampling sites from the northern Tunisian coast during June 2017. MPs were categorized according to type, colour and size. Representative MPs from the five sites were isolated for polymer identification using Fourier Transformed Infrared Spectroscopy in attenuated total reflectance mode (FTIR-ATR). Results showed that MPs were recovered, from all sediment samples, indicating for the first time, their extensive distribution in Tunisian coast. Concentrations varied from 141.20 ± 25.98 to 461.25 ± 29.74 items kg-1 dry weight. Fibres, fragments, Styrofoam®, pellets and films were the types registered in this study. With the exception of Menzel Bourguiba (MB), fibres significantly outnumbered plastic particles followed by fragments, Styrofoam®, films and pellets. The predominant colours are as follows: black > clear > white > red > blue > green for fibres, blue > white > clear > red > green > yellow > black for fragments, blue > white > black > clear for films while only white pellets and Styrofoam® were found. MPs particles ranged from 0.1 to 5 mm in length. A total of three polymer types were identified, polyethylene (PE), polypropylene (PP) and polystyrene (PS). Except for industrial pellets, the presence of MPs is likely due to the degradation of marine plastic debris accumulating in each site. This work provides original data of the presence of MPs in coastal sediments from Northern Tunisian coast.

Egyptian Activism against Female Genital Cutting as Catachrestic Claiming

Directory of Open Access Journals (Sweden)

An Van Raemdonck

2013-08-01

Full Text Available This paper deals with questions of the politics of location in knowledge and norm production within the context of Egyptian feminist activism for abandoning female genital cutting practices. It seeks to determine underlying schemes of international campaigning discourse and analyzes how these predicate and complicate Egyptian postcolonial activism. It draws on a broad literature study in addition to fieldwork in Cairo consisting of in-depth interviews with activists and policy makers. My focus is on the national Task Force against FGM from 1994 until 1999 and its subsequent cooptation by the National Council of Childhood and Motherhood. I argue through the concept of catachresis that location matters in setting the terms of anti-FGC discourse and its relation to religion.

On the presence of coastal upwelling along the northeastern Tyrrhenian coast

Science.gov (United States)

Martellucci, Riccardo; Melchiorri, Cristiano; Costanzo, Lorenzo; Marcelli, Marco

2017-04-01

The Mediterranean region shows a high climate variability due to the interactions between mid-latitude and tropical processes. This variability makes the Mediterranean a potentially vulnerable region to climatic changes. The present research aims to investigate the hydrographical response to Northerly wind in the northeastern Tyrrhenian coast, to identify the relations between upwelling events and teleconnection patterns. In the Tyrrhenian basin northerly winds flow between North-East and North-West and could be considered upwelling favorable winds. This atmospheric circulation can causes a divergent flow near the coast that generates a subsurface water flows inshore toward the coast up to the surface layer that is upwelling. This phenomenon strongly influence the marine ecosystems, contributing to the supply of nutrients and affecting the primary producers. In this context multi-platform observing system is an important tool to follow the evolution of these phenomena. Sea temperature and wind field acquired by the C-CEMS Observing system were used to identify upwelling phenomena between 2012 and 2016, in the coastal area of Civitavecchia, Northern Tyrrhenian sea, Italy. Moreover a thirty years' wind-driven upwelling conditions have been studied in the area. ERA-Interim (ECMWF) wind data for the period 1982-2012 have been used to compute the distribution of upwelling favorable wind events. These have been compared to "Copernicus Marine Environment Monitoring Service" Sea Surface Temperature (SST) to compute upwelling events. Upwelling favorable wind has been defined in the sector between Northwest and Northeast (Wd >330°N & Wd analysis. An increase of upwelling events in the Tyrrhenian coast is observed in the last thirty years; the occurrence of upwelling events has a seasonal oscillation, with a maximum frequency during winter and spring seasons. In the last decade an increase of these events in winter and a decrease in spring is observed; also a recurrence of

Diplomacy, Propaganda, and Humanitarian Gestures: Francoist Spain and Egyptian Jews, 1956-1968

Directory of Open Access Journals (Sweden)

Raanan Rein

2014-06-01

Full Text Available Historians still debate over the help extended by Francoist Spain to European Jews during the Holocaust. The Spanish dictatorship always exaggerated the extent of this assistance. This propagandist effort on the part of the Spanish regime to portray itself as the savior of Jews in distress, especially Jews of Sephardic origin, was put to the test during the 1950s and 1960s, when Madrid was asked to help Egyptian Jews following the 1956 and 1967 wars in the Middle East. Based on research in Spanish and Israeli archives, this article argues that: a Spain could have done more to help Egyptian Jews. Its policy was unclear and inconsistent. Moreover, the assistance that was finally given was intended mainly to improve the dictatorship’s image in the eyes of Western democratic public opinion; b the Francoist dictatorship did its best to prevent the settlement of Jews in Spain; c the help extended to Egyptian Jews owed more to the initiatives of individual Spanish diplomats than to the policy adopted by the Spanish government; d all this notwithstanding, the help given by Spain to Egyptian Jews should be appreciated and considered within the context of its overall effort to save Jews in distress in other Arab countries in the post-World War II period.

Climate Change Impacts on the Mediterranean Coastal Zones

International Nuclear Information System (INIS)

Brochier, F.; Ramieri, E.

2001-04-01

The main objective of this paper is to highlight the potential impacts of changes in climatic conditions and in related variables, which could affect coastal areas, as well as to identify potential response measures which could reduce the vulnerability of coastal systems and enhance their adaptability. Attention will be focused on the Mediterranean basin which is in the climate change context, a zone of great interest and of recent concern at the world scale by some features: strong ocean-atmosphere-land interactions; contrast between the small size of the sea and its significant role in the global climate system; possibility to use it at a scaled down model for the monitoring of environmental and climate evolution; critical environmental conditions of some areas and high human pressure; and strong geographical, socio-economic and climatic contrasts. The first section provides an introduction to the climate change issue, the past trends and the projections of future climate at the global scale. The second section presents the main features of the Mediterranean basin and some relevant regional projections of future climatic variables. The third section focuses on the main likely impacts on the Mediterranean coasts. Different coastal systems - such as islands, deltas, estuaries, coastal wetlands and coastal cities - and different climate change impacts - such as inundation, increased flooding, salinisation, salt water intrusion, desertification, and increased erosion - are addressed in this section. Finally the last section brings some conclusions and identify some strategies of adaptations and directions for future research aimed at improving our ability to predict and assess the local impacts of climate change in the region

Coastal lagoons, both hypersaline and freshwater, are common, but still understudied ecosystems. We describe, for the first time, using high throughput sequencing, the extant microbiota of two large and representative Mediterranean coastal lagoons, the hypersaline Mar Menor, and the freshwater Albufera de Valencia, both located on the south eastern coast of Spain. We show there are considerable differences in the microbiota of both lagoons, in comparison to other marine and freshwater habitats. Importantly, a novel uncultured sulfur oxidizing Alphaproteobacteria was found to dominate bacterioplankton in the hypersaline Mar Menor. Also, in the latter prokaryotic cyanobacteria were almost exclusively comprised by Synechococcus and no Prochlorococcus was found. Remarkably, the microbial community in the freshwaters of the hypertrophic Albufera was completely in contrast to known freshwater systems, in that there was a near absence of well known and cosmopolitan groups of ultramicrobacteria namely Low GC Actinobacteria and the LD12 lineage of Alphaproteobacteria.

First record and evidence of an established population of the North American mud crab Dyspanopeus sayi (Brachyura: Heterotremata: Panopeidae in the western Mediterranean

Directory of Open Access Journals (Sweden)

Christoph D. Schubart

2011-12-01

Full Text Available The panopeid crab Dyspanopeus sayi (Smith, 1869 is reported here from the Ebro Delta (Mediterranean coast of the Iberian Peninsula. Originally endemic to the Atlantic coast of North America, D. sayiz was involuntarily introduced into Britain, France and the Netherlands, and into the Adriatic and Black Sea within the last thirty years. Here we provide the first record of this species from the western Mediterranean Sea. Occurrences of ovigerous females at different localities of the delta and in different years provide evidence that the population is well established. Mitochondrial DNA confirms the identity of the species and indicates that the introduced population consists of at least three female lineages. The first zoeal stage of D. sayi was obtained in the laboratory from an ovigerous female captured in August 2010 with embryos in an advanced stage of development. The morphology of the zoea I is described here in detail and is similar to the one previously reported for native populations.

Alexithymia in Egyptian Substance Abusers.

Science.gov (United States)

El Rasheed, Amany Haroun

2001-03-01

Alexithymia is thought of as a trait that predisposes to drug abuse. Moreover, it is suggested to be related to type of the substance abused, with the worst-case scenario including a worse prognosis as well as tendency to relapse or even not to seek treatment at all. To address this important subject in Egyptian patients, a sample of 200 Egyptian substance abusers was randomly selected from inpatients in the Institute of Psychiatry, Ain Shams University, Egypt. The study also included 200 group-matched controls. DSM-IV criteria were used for assessment of substance use disorders, and toxicologic urine analysis was used to confirm the substances of abuse. Toronto Alexithymia Scale (TAS)-Arabic version was used for assessment of alexithymia. It was found that alexithymia was significantly more prevalent in the substance use disorders group as compared to healthy controls. It was also found that among the substance use disorders group, alexithymics reported more polysubstance abuse, more opiate use (other than heroin IV), lower numbers of hospitalizations, lower numbers of reported relapses, and a lower tendency to relapse as a result of internal cues compared to patients without alexithymia. Statistically significant associations were also found between alexithymia and more benzodiazepine abuse and nonpersistence in treatment. The results suggest that alexithymia should be targeted in a treatment setting for substance use disorders.

Changes in the Floating Plastic Pollution of the Mediterranean Sea in Relation to the Distance to Land.

Directory of Open Access Journals (Sweden)

Maria Luiza Pedrotti

Full Text Available The composition, size distribution, and abundance of floating plastic debris in surface waters of the Mediterranean Sea were analyzed in relation to distance to land. We combined data from previously published reports with an intensive sampling in inshore waters of the Northwestern Mediterranean. The highest plastic concentrations were found in regions distant from from land as well as in the first kilometer adjacent to the coastline. In this nearshore water strip, plastic concentrations were significantly correlated with the nearness to a coastal human population, with local areas close to large human settlements showing hundreds of thousands of plastic pieces per km2. The ratio of plastic to plankton abundance reached particularly high values for the coastal surface waters. Polyethylene, polypropylene and polyamides were the predominant plastic polymers at all distances from coast (86 to 97% of total items, although the diversity of polymers was higher in the 1-km coastal water strip due to a higher frequency of polystyrene or polyacrylic fibers. The plastic size distributions showed a gradual increase in abundance toward small sizes indicating an efficient removal of small plastics from the surface. Nevertheless, the relative abundance of small fragments (< 2 mm was higher within the 1-km coastal water strip, suggesting a rapid fragmentation down along the shoreline, likely related with the washing ashore on the beaches. This study constitutes a first attempt to determine the impact of plastic debris in areas closest to Mediterranean coast. The presence of a high concentration of plastic including tiny plastic items could have significant environmental, health and economic impacts.

Spatial variation of acid-volatile sulfide and simultaneously extracted metals in Egyptian Mediterranean Sea lagoon sediments.

Younis, Alaa M; El-Zokm, Gehan M; Okbah, Mohamed A

2014-06-01

In risk assessment of aquatic sediments, the immobilizing effect of acid-volatile sulfide (AVS) on trace metals is a principal control on availability and associated toxicity of metals to aquatic biota, which reduces metal bioavailability and toxicity by binding and immobilizing metals as insoluble sulfides. Spatial variation pattern of AVS, simultaneously extracted metals (SEM), and sediment characteristics were studied for the first time in surface sediment samples (0-20 cm) from 43 locations in Egyptian northern delta lagoons (Manzalah, Burullus, and Maryut) as predictors of the bioavailability of some divalent metals (Cu, Zn, Cd, Pb, and Ni) in sediments as well as indicators of metal toxicity in anaerobic sediments. The results indicated that the ∑SEM (Cu + Zn + Cd + Pb + Ni) values in sediments of lagoon Burullus had higher concentrations than those of Maryut and Manzalah. In contrast, AVS concentrations were considerably higher in lagoons Manzalah and Maryut and seemed to be consistent with the increase in organic matter than lagoon Burullus. Generally, the average concentrations of the SEM in all lagoons were in the order of Zn > Cu > Ni > Pb > Cd. The ratios of ∑SEM/AVS were less than 1 at all the sampling stations except at one station in lagoon Maryut as well as four stations located in lagoon Burullus (∑SEM/AVS > 1), which suggests that the metals have toxicity potential in these sediments. Therefore, SEM concentrations probably are better indicators of the metal bioavailability in sediments than the conventional total metal concentrations.

Count like an egyptian a hands-on introduction to ancient mathematics

Reimer, David

2014-01-01

The mathematics of ancient Egypt was fundamentally different from our math today. Contrary to what people might think, it wasn't a primitive forerunner of modern mathematics. In fact, it can't be understood using our current computational methods. Count Like an Egyptian provides a fun, hands-on introduction to the intuitive and often-surprising art of ancient Egyptian math. David Reimer guides you step-by-step through addition, subtraction, multiplication, and more. He even shows you how fractions and decimals may have been calculated-they technically didn't exist in the land of the pharaohs.

Environmental roots of the late bronze age crisis.

Directory of Open Access Journals (Sweden)

David Kaniewski

Full Text Available The Late Bronze Age world of the Eastern Mediterranean, a rich linkage of Aegean, Egyptian, Syro-Palestinian, and Hittite civilizations, collapsed famously 3200 years ago and has remained one of the mysteries of the ancient world since the event's retrieval began in the late 19(th century AD/CE. Iconic Egyptian bas-reliefs and graphic hieroglyphic and cuneiform texts portray the proximate cause of the collapse as the invasions of the "Peoples-of-the-Sea" at the Nile Delta, the Turkish coast, and down into the heartlands of Syria and Palestine where armies clashed, famine-ravaged cities abandoned, and countrysides depopulated. Here we report palaeoclimate data from Cyprus for the Late Bronze Age crisis, alongside a radiocarbon-based chronology integrating both archaeological and palaeoclimate proxies, which reveal the effects of abrupt climate change-driven famine and causal linkage with the Sea People invasions in Cyprus and Syria. The statistical analysis of proximate and ultimate features of the sequential collapse reveals the relationships of climate-driven famine, sea-borne-invasion, region-wide warfare, and politico-economic collapse, in whose wake new societies and new ideologies were created.

Are lionfish set for a Mediterranean invasion? Modelling explains why this is unlikely to occur.

Science.gov (United States)

Johnston, Matthew W; Purkis, Sam J

2014-11-15

The Atlantic invasion of Indo-Pacific lionfish (Pterois volitans/P. miles) has been as swift as it has been disastrous. Lionfish are non-native to the Mediterranean, but an invasion is perhaps even more likely than for the Atlantic. First, as for the Atlantic, there are many major cities on the coast of the Mediterranean (where aquarium-keeping is a common practice and chances of accidental and deliberate releases are high), and second, lionfish are native to the Red Sea, to which the Mediterranean is connected via the Suez Canal. Furthermore, there have already been four records of lionfish in the Mediterranean and so the pretext for an invasion is already in place. Up until now, however, it has been difficult to gauge the likelihood of an infestation of lionfish in the Mediterranean as, unlike the Atlantic, this sea has not been examined in terms of its hydrodynamics, ocean climate, and bathymetry, all factors known to be relevant to assessing the possibility of invasion. Motivated by this knowledge-gap, this study used remote sensing and computer modeling to investigate the connectivity between areas along the Mediterranean coastline that fulfill the necessary physical criteria to serve as potential lionfish habitat. Model results from the Mediterranean were compared and contrasted to those from the Atlantic and eastern Pacific. The Atlantic was considered because the lionfish invasion there has been voracious. Meanwhile, the eastern Pacific is interesting as a site without native lionfish, but with plenty of opportunity for their introduction, but no invasion yet recorded. Results indicated that, unlike in the Atlantic, connectivity among potential lionfish habitats in the Mediterranean was low in the study and comparable to that in the eastern Pacific. Although oceanographic conditions in the Mediterranean were found unfavorable for wide dispersion of lionfish larvae, hotspots where numerous lionfish sightings would forewarn an impending invasion were

We report two Egyptian male genomes (EGP1 and EGP2) sequenced at ~ 30× sequencing depths. EGP1 had 4.7 million variants, where 198,877 were novel variants while EGP2 had 209,109 novel variants out of 4.8 million variants. The mitochondrial haplogroup of the two individuals were identified to be H7b1 and L2a1c, respectively. We also identified the Y haplogroup of EGP1 (R1b) and EGP2 (J1a2a1a2 > P58 > FGC11). EGP1 had a mutation in the NADH gene of the mitochondrial genome ND4 (m.11778 G > A) that causes Leber's hereditary optic neuropathy. Some SNPs shared by the two genomes were associated with an increased level of cholesterol and triglycerides, probably related with Egyptians obesity. Comparison of these genomes with African and Western-Asian genomes can provide insights on Egyptian ancestry and genetic history. This resource can be used to further understand genomic diversity and functional classification of variants as well as human migration and evolution across Africa and Western-Asia. Copyright © 2017.

Khaled Asfour

2014-11-01

Full Text Available In Vitruvius’ treatise, what makes good architecture is its ability to communicate to the public particular messages that reflects the program of the building with spaces and components arranged in an orderly way. According to Vitruvius these messages when acknowledges by the public the building posses strong character. This research discusses this idea by reflecting on the 1895 competition of the Egyptian Museum project. Marcel Dourgnon, the French architect of the winning scheme, showed profound understanding of character resulting in a building that had positive vibe with the local community.  Today Vitruvius’ idea is still living with us. Norman Foster succeeded in upgrading the British Museum in a way that addressed all cultures of the world through his grand atrium design.  Similarly, Emad Farid and Ramez Azmy revived the presence of the Egyptian Museum in public cognition.  Spatial experience that evokes similar perceptions to all its visitors is a timeless piece that transcends cultural boundaries.

The ancient Egyptians mummified an abundance of cats during the Late Period (664 - 332 BC). The overlapping morphology and sizes of developing wildcats and domestic cats confounds the identity of mummified cat species. Genetic analyses should support mummy identification and was conducted on two long bones and a mandible of three cats that were mummified by the ancient Egyptians. The mummy DNA was extracted in a dedicated ancient DNA laboratory at the University of California – Davis, then directly sequencing between 246 and 402 bp of the mtDNA control region from each bone. When compared to a dataset of wildcats (Felis silvestris silvestris, F. s. tristrami, and F. chaus) as well as a previously published worldwide dataset of modern domestic cat samples, including Egypt, the DNA evidence suggests the three mummies represent common contemporary domestic cat mitotypes prevalent in modern Egypt and the Middle East. Divergence estimates date the origin of the mummies’ mitotypes to between two and 7.5 thousand years prior to their mummification, likely prior to or during Egyptian Predyanstic and Early Dynastic Periods. These data are the first genetic evidence supporting that the ancient Egyptians used domesticated cats, F. s. catus, for votive mummies, and likely implies cats were domesticated prior to extensive mummification of cats.

A comprehensive climatology of migratory anticyclones affecting the Mediterranean was generated with the aid of the University of Melbourne finding and tracking algorithm, applied to 34 years (1979-2012) of ERA-Interim mean sea level pressures. The algorithm is employed for the first time to study anticyclones in this region, thus, its robustness and reliability in efficiently capturing the individual characteristics of the anticyclonic tracks in the Mediterranean were checked and verified. The tracks and the statistical properties of the migratory systems revealed two major anticyclonic routes: over the northern (i.e. from the Iberian towards the Balkan Peninsula) and over the southern (i.e. the North Africa coast) Mediterranean barriers. A transition of the system density and anticyclogenesis maxima is evident throughout the year from solely continental environments in winter and autumn to also maritime in spring and summer. These variations can be attributed to the seasonal variability of the major anticyclonic systems that are involved in this region. The interannual variability of synoptic systems can be attributed to natural low frequency variability. The interannual variations of the system density and strength were linked to the Northern Hemisphere modes of atmospheric variability; e.g. more (less) antiyclonic tracks are observed around the Mediterranean basin during periods of positive (negative) NAO, with a consequent enhancement (decline) of the pressure field. Moreover, possible trends in the frequency and intensity of the anticyclonic systems were explored in an attempt to examine any impacts of recent global warming conditions. Positive trends of system density, genesis and intensity prevail during the cold period over the greater area around the Mediterranean basin. During summer, the general increase in system density is not followed by a corresponding tendency in the number of the generating systems and the intensity. Regarding the depth of the

A major tsunami-like event, locally known as `marrobbio', impacted the southwestern coast of Sicily on 25-26 June 2014. The event was part of a chain of hazardous episodes in the Mediterranean and Black seas during the last week of June 2014 resulting from an anomalous atmospheric system ("tumultuous atmosphere") propagating eastward over the region. The synoptic patterns and vertical structure of the atmosphere over Sicily at the time of the event indicate that atmospheric wave ducting was responsible for the generation of tsunamigenic air pressure disturbances that produced especially high sea level responses ("meteotsunamis") at certain sites along the Sicilian coast. The strongest sea level oscillations were observed at Mazara del Vallo, where a 1-m meteotsunami bore, propagating upstream in the Mazaro River, was generated. The combined effects of external resonance (Proudman resonance on the western Sicilian shelf) and internal resonant conditions (bathymetric and topographic characteristics of specific sites) were found to be the key factors that caused the meteotsunami (marrobbio phenomenon) on the coast of Sicily and the meteobore at Mazara del Vallo.

Transferability of the Mediterranean Diet to Non-Mediterranean Countries. What Is and What Is Not the Mediterranean Diet.

2017-11-08

Substantial evidence has verified the Mediterranean diet's (MedDiet) nutritional adequacy, long-term sustainability, and effectiveness for preventing hard clinical events from cardiovascular disease (CVD), as well as increasing longevity. This article includes a cumulative meta-analysis of prospective studies supporting a strong inverse association between closer adherence to the MedDiet and the incidence of hard clinical events of CVD. The MedDiet has become an increasingly popular topic of interest when focusing on overall food patterns rather than single nutrient intake, not only in Mediterranean countries, but also globally. However, several myths and misconceptions associated with the traditional Mediterranean diet should be clearly addressed and dispelled, particularly those that label as "Mediterranean" an eating pattern that is not in line with the traditional Mediterranean diet. The transferability of the traditional MedDiet to the non-Mediterranean populations is possible, but it requires a multitude of changes in dietary habits. New approaches for promoting healthy dietary behavior consistent with the MedDiet will offer healthful, sustainable, and practical strategies at all levels of public health. The following article presents practical resources and knowledge necessary for accomplishing these changes.

Full Text Available A comparative study of the feeding ecology of Nephrops norvegicus was carried out on a seasonal basis simultaneously in seven locations in the Eastern and Western Mediterranean and the adjacent Atlantic: the south coast of Portugal, Faro; the Alboran Sea, Malaga; the Catalan Sea, Barcelona; the Ligurian Sea, Genoa; theTyrrhenian Sea, Pisa; the Adriatic Sea, Ancona and the Aegean Sea, Gulf of Euboikos. The major groups observed (frequency of occurrence method in the stomachs of Nephrops norvegicus were decapod crustaceans, other crustaceans (euphausids and peracarids and fish. The results obtained showed no significant differences between sites or seasons, and can be considered very consistent. All major taxa were present in the diet at all sites and for all seasons, a fact that can be explained by the great similarity of the bathyal fauna in all sites, which provide a major trophic resource for N. norvegicus. The percentage of fullness was also estimated per site and season, and we registered a clear decrease of this value during the summer period for all sites, except the Tyrrheanian Sea, where the lowest value was found in autumn. PCA - analysis did not clearly separate the regions (sites. The Shannon-Weaver (H´, index of diversity, was also determined per site and season, and we found a significant difference between the values of the Atlantic coast and the Western Mediterranean when compared with those of the Eastern Mediterranean.

The accumulation of large boulders related to waves generated by either tsunamis or extreme storm events have been observed in different areas of the Mediterranean Sea. Along the eastern low-lying rocky coasts of Malta, five sites with large boulder deposits have been investigated, measured and mapped. These boulders have been detached and moved from the nearshore and the lowest parts of the coast by sea wave action. In the Sicily-Malta channel, heavy storms are common and originate from the NE and NW winds. Conversely, few tsunamis have been recorded in historical documents to have reached the Maltese archipelago. We present a multi-disciplinary study, which aims to define the characteristics of these boulder accumulations, in order to assess the coastal geo-hazard implications triggered by the sheer ability of extreme waves to detach and move large rocky blocks inland. The wave heights required to transport 77 coastal boulders were calculated using various hydrodynamic equations. Particular attention was given to the quantification of the input parameters required in the workings of these equations, such as size, density and distance from the coast. In addition, accelerator mass spectrometry (AMS) 14C ages were determined from selected samples of marine organisms encrusted on some of the coastal boulders. The combination of the results obtained both by the hydrodynamic equations, which provided values comparable with those observed and measured during the storms, and radiocarbon dating suggests that the majority of the boulders have been detached and moved by intense storm waves. These boulders testify to the existence of a real hazard for the coasts of Malta, i.e. that of very high storm waves, which, during exceptional storms, are able to detach large blocks of volumes exceeding 10 m3 from the coastal edge and the nearshore bottom, and also to transport them inland. Nevertheless, the occurrence of one or more tsunami events cannot be ruled out, since

Over the last decade, the Internet has become an important source of health-related information for a wide range of users worldwide. Yet, little is known about the personal characteristics of Egyptian Internet users who search for online health information (OHI). The aim of the study was to identify the personal characteristics of Egyptian OHI seekers and to determine any associations between their personal characteristics and their health information-seeking behavior.  This cross-sectional questionnaire study was conducted from June to October 2015. A Web-based questionnaire was sent to Egyptian users aged 18 years and older (N=1400) of a popular Arabic-language health information website. The questionnaire included (1) demographic characteristics; (2) self-reported general health status; and (3) OHI-seeking behavior that included frequency of use, different topics sought, and self-reported impact of obtained OHI on health behaviors. Data were analyzed using descriptive statistics and multiple regression analysis. A total of 490 participants completed the electronic questionnaire with a response rate equivalent to 35.0% (490/1400). Regarding personal characteristics, 57.1% (280/490) of participants were females, 63.4% (311/490) had a university level qualification, and 37.1% (182/490) had a chronic health problem. The most commonly sought OHI by the participants was nutrition-related. Results of the multiple regression analysis showed that 31.0% of the variance in frequency of seeking OHI among Egyptian adults can be predicted by personal characteristics. Participants who sought OHI more frequently were likely to be female, of younger age, had higher education levels, and good self-reported general health. Our results provide insights into personal characteristics and OHI-seeking behaviors of Egyptian OHI users. This will contribute to better recognize their needs, highlight ways to increase the availability of appropriate OHI, and may lead to the

Baseline study of the distribution of marine debris on soft-bottom habitats associated with trawling grounds in the northern Mediterranean

Full Text Available The present study aims to analyse the local and regional variability in the density and typology of marine debris on fishing grounds on the northern Mediterranean continental shelf, and to test relationships between marine litter and trawl fishing activity. Moreover, the colonization of plastics was examined in order to study the importance of plastics as a source of impact on marine communities and their further environmental implications. This study surveyed 11 sites, associated with trawling grounds and subjected to different levels of fishing intensity, located in four areas of the Mediterranean: one in Italy, the Central Tyrrhenian coast, one in Greece, the eastern Ionian coast, and two in Spain, the Murcian and Catalan coasts. Samples were collected during an oceanographic cruise undertaken from the 21 May to the 24 June 2009. Results showed geographical variation in the density of marine debris which ranged from 0 to 405 pieces per hectare in the surveyed areas, plastics being the dominant components. Variability within sites was higher than between areas, indicating small-scale patchiness in the distribution of the debris over the seafloor. Though the study areas were within trawling grounds, the density of debris was not significantly correlated with fishing effort. More than 30% of plastics were between 10 and 20 cm width/length, and more than 40% of the plastics were colonized by a biofilm of microorganisms, suggesting indirect effects on benthic communities.

DNA barcoding reveals a cryptic nemertean invasion in Atlantic and Mediterranean waters

Science.gov (United States)

Fernández-Álvarez, Fernando Ángel; Machordom, Annie

2013-09-01

For several groups, like nemerteans, morphology-based identification is a hard discipline, but DNA barcoding may help non-experts in the identification process. In this study, DNA barcoding is used to reveal the cryptic invasion of Pacific Cephalothrix cf. simula into Atlantic and Mediterranean coasts. Although DNA barcoding is a promising method for the identification of Nemertea, only 6 % of the known number of nemertean species is currently associated with a correct DNA barcode. Therefore, additional morphological and molecular studies are necessary to advance the utility of DNA barcoding in the characterisation of possible nemertean alien invasions.

AN OBSERVATION ON NOMINAL SENTENCES WITH N-DEMONSTRATIVES IN CLASSICAL EGYPTIAN

Institute of Scientific and Technical Information of China (English)

EdmundS.Meltzer

1995-01-01

The employment of both "bipartite" and "tripartite" nominal sentence patterns containing demonstratives of the n-series in Middle Egyptian~1 shows a characteristic sufficiently consistent to warrant the suggestion that a semantic constraint is operative: VIZ., that those sentences are employed with NPs that are [-PERSON], not [+PERSON]. Therefore, sentences such as ~*R’/it.i/ink (pw) nn/nf(3)/n3/nw are excluded. In a sentence suc(?) as bit.i pw n3 "This is my character/conduct"~2, bit.i "my character/conduct" is [-PERSON], whereas one could not say, e.g., ~*s3. i pw n3 "This is my son." According to this hypothesis, all Middle Egyptian

Ancient Egyptian chronology and the astronomical orientation of pyramids

Science.gov (United States)

Spence, Kate

2000-11-01

The ancient Egyptian pyramids at Giza have never been accurately dated, although we know that they were built approximately around the middle of the third millennium BC. The chronologies of this period have been reconstructed from surviving lists of kings and the lengths of their reigns, but the lists are rare, seldom complete and contain known inconsistencies and errors. As a result, the existing chronologies for that period (the Old Kingdom) can be considered accurate only to about +/-100 years, a figure that radiocarbon dating cannot at present improve. Here I use trends in the orientation of Old Kingdom pyramids to demonstrate that the Egyptians aligned them to north by using the simultaneous transit of two circumpolar stars. Modelling the precession of these stars yields a date for the start of construction of the Great Pyramid that is accurate to +/-5 yr, thereby providing an anchor for the Old Kingdom chronologies.

Aspects of the international migration of Egypt's urban educated elite are examined using data from a 1987 survey of 874 Egyptian university students. "Specific questions considered are: What has been the migration experience of these elites? In what ways has this experience changed over time and what changes are likely to occur in the future? What are some of the characteristics of the potential participants in these changes? How do answers to these questions vary among different segments of this elite and what can be inferred about the class nature of Egyptian migration processes?" excerpt

The main aim of this study was to isolate and characterize microsatellite loci in Cneorum tricoccon (Cneoraceae), a Mediterranean shrub relict of the early Tertiary, which inhabits western Mediterranean islands and coasts. Microsatellites will be useful for investigating biogeography and landscape genetics across the species distribution range, including current or past gene flow. Seventeen microsatellite loci were characterized, of which 10 were polymorphic and amplified for a total of 56 alleles in three populations of C. tricoccon. The markers revealed average coefficients of expected heterozygosity (H(e) = 0.425), observed heterozygosity (H(o) = 0.282), and inbreeding coefficient value per population (F(IS) = 0.408). These microsatellite primers will potentially be useful in the study of population and landscape genetics, conservation status of isolated populations, island-continental distribution, current or historical movements between populations, and in the investigation of the consequences of dispersal mechanisms of these plants.

Fisheries in the Mediterranean

Directory of Open Access Journals (Sweden)

C. PAPACONSTANTINOU

2000-06-01

Full Text Available The aim of this paper is to give a description of the Mediterranean fisheries, and its level of exploitation and to address the main questions dealing with its management. The Mediterranean is a semi-enclosed marine area with generally narrow continental shelves. The primary production of the Mediterranean is among the lowest in the world (26-50g C m-2 y-1. The Mediterranean fisheries can be broken down into three main categories: small scale fisheries, trawling and seining fisheries, which operated on demersal, small pelagic and large pelagic resources. After a general description of the state of the resources in the different areas of the Mediterranean it is concluded that (a the overall pictures from the western to the eastern Mediterranean are not considerably different, (b the total landings in the Mediterranean have been increased the last decades, and (c from the perspective of stock assessment, the very few available time series data show stable yield levels. In general fisheries management in the Mediterranean is at a rela- tively early stage of development, judging by the criteria of North Atlantic fisheries. Quota systems are generally not applied, mesh-size regulations usually are set at low levels relative to scientific advice, and effort limitation is not usually applied or, if it is, is not always based on a formal resource assessment. The conservation/management measures applied by the Mediterranean countries can be broadly separated into two major categories: those aiming to keep the fishing effort under control and those aiming to make the exploitation pattern more rational. The most acute problems in the management of the Mediterranean resources are the multispecificity of the catches and the lack of reliable official statistics.

Comparative Study Between The IAEA Model Regulations and The Egyptian Nuclear Law

2015-01-01

This study deals with the security of radioactive sources due to its great importance, in order to provide the adequate security of these sources from the threat of theft, sabotage, illegal seizure through doing a comparison between the model regulations of the International Atomic Energy Agency (IAEA) (11) and the Egyptian law (No. 7/2010) that regulates nuclear and radiation activities and its executive regulations. The Egyptian legislator has put a chapter entitled n uclear security w ith the aim of organizing the security of nuclear materials. However, there was a review to some regulatory rules issued by the IAEA on the security of these sources which include the responsibilities of the licensee towards it. This chapter also, addressed the security culture through rehabilitation and training, in addition to the obligations of the competent authorities who is responsible for the process of issuing the license when full requirements are met. It has been shown that the Egyptian law and its executive regulations contained the rule that provides the necessary protection for these radioactive sources. Furthermore, more regulations are still needed to provide adequate security and more protection for the radioactive sources and its facilities

Egyptian And International Automotive Diesel. Fuels: Specifications Meeting Challenges To Refining Industry

International Nuclear Information System (INIS)

Zayed, A.M.; EI Shamy, A.A.

2004-01-01

This paper presents a brief summary and comparison of Egyptian automotive diesel fuel to the international one. Recent legislation all over the world, requiring further reduction in sulfur, aromatics, T 90 and T 95 and increasing cetane value of the transportation diesel fuels, presents numerous technical and economic challenges to the refiners. While refiners grapple with these challenges, they will also face pressure from the increased demand of transportation diesel fuel and tighter capital restrictions. Overcome of these challenges makes a fair competition. A comparison of the Egyptian automotive diesel fuel and the international one will be a guide to locally and globally facing these challenges

2011-03-01

The study was aimed at describing the temperature humidity index (THI) dynamics over the Mediterranean basin for the period 1951-2007. The THI combines temperature and humidity into a single value, and may help to predict the effects of environmental warmth in farm animals. In particular, on the basis of THI values, numerous studies have been performed to establish thresholds for heat stress in dairy cows. The THI was calculated by using monthly mean values of temperature and humidity obtained from the National Center for Environmental Prediction/National Center for Atmospheric Research reanalysis project. The analysis demonstrated a high degree of heterogeneity of THI patterns over the Mediterranean basin, a strong north-south gradient, and an overall warming during the study period, which was particularly marked during summer seasons. Results indicated that several areas of the basin present summer THI values which were unfavorable to cow welfare and productivity, and that risk of heat stress for cows is generally greater in the countries of the south coast of the basin. Furthermore, THI data from the summer 2003 revealed that severe positive anomalies may impact areas normally characterized by a favorable climate for animal production. In conclusion, THI dynamics should be taken into careful consideration by farmers and policy makers operating in Mediterranean countries when planning investments in the sector of animal production. The investments should at least partially be directed towards implementation of adaptation measures, which may help to alleviate the impact of hot on farm animals welfare, performance and health.

For the laboratory experiment, several wall fragments of the Malqata palace in ancient Egypt (18th Dynasty, ca. 1390 B.C.) were investigated. In the field experiment, the block of Ramesses II (19th Dynasty, ca. 1270 B.C.), the Wooden Coffin of Neb-sny (18th Dynasty, ca. 1400 B.C.), the Funerary Stele of Amenemhat (11th Dynasty, ca. 2000 B.C.), and the painted walls of the Tomb of Userhat (18th Dynasty, ca. 1400 B.C.) were investigated. From white and blue colored parts, huntite and Egyptian blue were found, respectively, which are a very rare mineral and an artificial pigment prepared only in ancient Egypt, respectively. (author)

Full Text Available The purpose of this study was to investigate canal configuration of mandibular first premolars in an Egyptian population. Two hundred fifty human extracted mandibular first premolars were collected from Egyptian patients and a small hole in the center of the occlusal surface of each tooth was made perforating the roof of the pulp chamber. Teeth were decalcified by immersing in nitric acid and dehydrated in ascending concentrations of ethyl alcohol. A waterproof black ink was passively injected from the occlusal hole into pulp system and stained teeth were immersed in methyl salicylate solution for clearing. Standardized pictures of the cleared teeth were obtained and anatomical features of the root canal were observed. The average length of the mandibular first premolar teeth was 22.48 ± 1.74 mm, one-rooted teeth were 96.8% and the two-rooted were 3.2%. Vertucci Type I canal configuration represented the highest percentage (61.2% followed by Type V (16.4%, Type IV (13.2%, Type II (5.6% and Type III (2.8%. Vertucci Type VI canal configuration represented the lowest percentage (0.4% and a complex configuration was found in one tooth. Accessory canals were detected in 22.8% and inter-canal connections were observed in 24.8% while 54% showed apical delta. Such knowledge is clinically useful for localization and negotiation of canals of mandibular first premolar, as well as their subsequent management in Egyptian population.

Xeroderma pigmentosum (XP) is a rare autosomal recessive hereditary disease characterized by hyperphotosensitivity, DNA repair defects and a predisposition to skin cancers. The most frequently occurring type worldwide is the XP group A (XPA). There is a close relationship between the clinical features that ranged from severe to mild form and the mutational site in XPA gene. The aim of this study is to carry out the mutational analysis in Egyptian patients with XP-A. This study was carried out on four unrelated Egyptian XP-A families. Clinical features were examined and direct sequencing of the coding region of XPA gene was performed in patients and their parents. Direct sequencing of the whole coding region of the XPA gene revealed the identification of two homozygous nonsense mutations: (c.553C >T; p.(Gln185)) and (c.331G>T; p.(Glu111)), which create premature, stop codon and a homodeletion (c.374delC: p.Thr125Ilefs 15) that leads to frameshift and premature translation termination. We report the identification of one novel XPA gene mutation and two known mutations in four unrelated Egyptian families with Xermoderma pigmentosum. All explored patients presented severe neurological abnormalities and have mutations located in the DNA binding domain. This report gives insight on the mutation spectrum of XP-A in Egypt. This would provide a valuable tool for early diagnosis of this severe disease. © 2013 Elsevier B.V. All rights reserved.

The biodiversity of the Mediterranean Sea: estimates, patterns, and threats.

Directory of Open Access Journals (Sweden)

Marta Coll

Full Text Available The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists. We also assessed overall spatial and temporal patterns of species diversity and identified major changes and threats. Our results listed approximately 17,000 marine species occurring in the Mediterranean Sea. However, our estimates of marine diversity are still incomplete as yet-undescribed species will be added in the future. Diversity for microbes is substantially underestimated, and the deep-sea areas and portions of the southern and eastern region are still poorly known. In addition, the invasion of alien species is a crucial factor that will continue to change the biodiversity of the Mediterranean, mainly in its eastern basin that can spread rapidly northwards and westwards due to the warming of the Mediterranean Sea. Spatial patterns showed a general decrease in biodiversity from northwestern to southeastern regions following a gradient of production, with some exceptions and caution due to gaps in our knowledge of the biota along the southern and eastern rims. Biodiversity was also generally higher in coastal areas and continental shelves, and decreases with depth. Temporal trends indicated that overexploitation and habitat loss have been the main human drivers of historical changes in biodiversity. At present, habitat loss and degradation, followed by fishing impacts, pollution, climate change, eutrophication, and the establishment of alien species are the most important threats and affect the greatest number of taxonomic groups. All these impacts are expected to grow in importance in the future, especially climate change and habitat degradation.

The number of alien species in the Mediterranean Sea is steadily increasing and it seems that the pace has been accelerating since the turn of the century (Galil et al. 2014). In 2015 alone five additional fish species have been reported, Epinephelus geoffroyi (Klunzinger, 1870) (Golani et al. 2015); Stolephorus indicus (van Hasselt, 1823) (Fricke et al. 2015); Sardinella gibbosa (Bleeker, 1849) (Stern et al. 2015); Mobula japanica (Müller & Henle, 1841) (Capapé et al. 2015); and Cryptocentrus caeruleopunctatus (Rüppell, 1830) (Rothman & Goren 2015). Among the ca. 100 alien fish species reported from the Mediterranean to date (Galil & Goren 2014), five Indo-Pacific species belong to the genus Epinephelus Bloch, 1793: Epinephelus coioides (Hamilton, 1822), Epinephelus fasciatus (Forsskål, 1775), Epinephelus malabaricus (Bloch and Schneider, 1804) Epinephelus merra Bloch, 1793 (Golani et al. 2013a) and Epinephelus geoffroyi (Klunzinger, 1870) (Golani et al. 2015). Additional alien Epinephelus species reported from the Mediterranean are excluded for various reasons (Golani et al. 2013b). Here we report the finding of a sixth Indo-Pacific species of this genus along the Mediterranean coast of Israel.

The existence of dwarfism is amply documented in ancient Egypt due to the rich biological and artistic legacies. In previous articles published in this journal, I discussed the roles of people with skeletal dysplasia in ancient Egyptian civilization. In this article I, along with my Egyptian and American colleagues, describe two skeletons of dwarfs that date to 2700-2184 BCE and were unearthed from a funerary complex near the Great Pyramids in Giza. The first skeleton belongs to a high official, Per-ni-ankh-w, who died between 45 and 50 years of age. His statue is on display in the Egyptian Museum of Cairo. The second skeleton belongs to a pregnant female worker found with a fetus in situ. Her estimated age at death was 25-30 years. She most likely died during childbirth due to a small pelvic outlet as supported by her narrow sacrum. The fetal bones appear normal. Radiological examination of both skeletons confirmed the clinical diagnosis of achondroplasia. Ancient Egyptians concerned themselves with the search for spiritual fulfillment through the tradition of moral teachings. Amenemope, a wise man who lived during the reign of Amenhotep III (1391-1354 BCE), advocated respect toward individuals with disabilities: Do not jeer at a blind man nor tease a dwarf, Neither interfere with the condition of a cripple. Do not taunt a man who is in the hand of God, Nor scowl at him if he errs. In summary, artistic, biological, and written resources indicate that dwarfs were well integrated in ancient Egyptian society. Copyright © 2011 Wiley-Liss, Inc.

Using coastal lagoons to better constrain the isostatic signal in the western Mediterranean Sea

Coastal lagoons represent a very common feature of the microtidal Mediterranean coastlines. They are inland waterbodies, usually developing parallel to the coast, typically separated from the open sea by a sandy barrier. One or more restricted inlets ensure their continuous or intermittent connection to the open sea. The water depth is generally less than 1 m and seldom exceeds a few meters. They represent a very useful proxy for the reconstruction of Mediterranean Relative Sea Level (RSL). However, caution should be used in the definition of a correct indicative meaning that can be obtained only with a multiproxy analysis of both sedimentary features and faunal assemblages of the cores extracted in marshy to lagoonal environment. We report here the results of a wide coring campaign we carried out in in the last 2 years in a number of Mediterranean lagoons located close to important archaeological settlements in Corsica (France) Sardinia (Italy) and Mallorca Island (Spain). The multiproxy analysis of the cores allowed defining the depositional environments and their relationship (or non relationship) with the former mean sea level. These data were chronologically supported by a significant dataset of more than 100 new 14C dating performed on organic sediments, wood, plant remains and marine/lagoonal shells. We then produced alarge amount of new data to constrain the RSL evolution in the center of Western Mediterranean where the available geophysical models predict the largest glacio-hydro isostatic (GIA) influence at basin scale. However, such models where tested only on a limited dataset mainly composed of archaeological RSL indicators (i.e. last 2 ka BP). Our new record, expanding the last 10 ka BP, significantly improves the ability to define the general anatomy of Mediterranean Holocene RSL changes and to constrain the maximal GIA magnitude in the basin.

Learning is always a joyful experience for any human being and must always remain so. Children are happiest when they learn through play. The philosophy of my life is to keep encouraging children to think beyond they could achieve easily. I understand children are adaptive to change and take things with an open mind. They are ready to experiment new things and dare to dream big. I am fortunate to be a teacher by profession and thus I always attempt experimenting, observing and participating with other children and adults. Education is not about moulding children the way you think they should be. It is about organizing the natural longing in a human being to know. From birth children are active participants in building their own understanding. I always prepare the environment to help each child build on what they already know. It is such a great pleasure to observe every young kid become excited and curious to know when we teach them.

Information on seagrass paleo-ecology is very scarce because detailed seagrass paleorecords are virtually lacking. The endemic Mediterranean seagrass Posidonia oceanica conjugates two unusual features that allow the reconstruction of the past history of the plant at two different time scales. On the one hand, the study of the leaf sheaths that remain attached to the rhizomes after leaf abcision (lepidochronology), allows to differentiate up to 30 yearly cycles. On the other hand, radiocarbon dating of peat-like deposits derived from Posidonia oceanica rhizomes and roots ('mattes'), reveals a chronological organic record of the plant spanning several thousands of years. Changes in the isotopic signature (δ 13 C) of the sheaths along Posidonia rhizomes from a meadow off Medes Islands (NW Mediterranean, Spain), were highly correlated with changes in annual leave production and with water transparency. These relationships and the isotopic analysis of sheath debris from several Posidonia peats along the Spanish Mediterranean coast are used to make some preliminary inferences about long-term meadow history. Several phenomena potentially making difficult the interpretation of the information contained in Posidonia peats are critically discussed. It is concluded that a detailed study of P. oceanica peats will open new vistas in Mediterranean paleo-ecological and paleo-environmental research (author)

The Egyptian Arab Spring and Political Islam

Full Text Available This study elaborates and analyzes the phenomenon and concept of political Islam, the reasons of the increased role of the Islamists and their political and reformist tendencies in the light of the Egyptian revolution of Arab Spring, reasons and the main factors that have contributed on their advent into power and their influence in that time, the issue of the application of Islamic Sharia and complex realities about this dilemma. The revolutions of Arab Spring, including the Egyptian revolution, are considered one of the most important and most dangerous events in the XXI century after the terrorist attacks of 11 September 2001, not only in the Middle East but throughout the world because of their impact on peace and global security. The growth of the phenomenon of political Islam and the advent of Islamists into power in Egypt has represented one of the most remarkable features of this sudden revolution. No doubt that the issue of the relationship between Islam and the state's political system raises many confusing questions for many people. In this sense the importance of this study will directly identify the fact that the leadership of Islamists in Egypt is not the implementation of Islamic Sharia but their movements and ideology.

Currents and upwelling along the Latium coasts in the Central Tyrrhenian Sea (western Mediterranean

Directory of Open Access Journals (Sweden)

V. Rossi

1995-04-01

Full Text Available In this study, springtime coastal currents along the Latium coast and their relation to external forcings, mainly wind stress curl and atmospheric pressure, are analysed. As a main result, we find that hydrographical measurements reveal currents parallel to the bottom isobaths, but with isopycnal sloping upwards towards the coast, suggesting the importance of upwellings in determining the coastal currents. This is confirmed by thermal satellite data showing the presence of a ~10-km-wide patch of cold water east of Mount Argentario, i.e. a cyclonic vortex. The current meter data give rather small values of the time-averaged alongshore velocities (~2 cm s–1 for most current meters and ~3 cm s–1 for the current meter placed immediately off the Argentario and also smaller values for the offshore velocities. The correlation between these two types of currents is rather poor; this is also due to the variability characteristic of a wind-induced upwelling. Finally, we obtain a value of 0.74 for the correlation between the alongshore current (first mode of Empirical Orthogonal Functions decomposition and the wind stress if a 23-h time lag is assumed.

Limited data are available on the genetics of rheumatoid arthritis (RA) in Egyptians. Therefore, we investigated whether the confirmed genetic risk factors for RA in Europeans and/or Asians contribute to RA susceptibility in Egyptians. A set of seven single-nucleotide polymorphisms (SNPs) in the vicinity of CD28, TNFAIP3, PTPN22, PADI4 and HLA-DRA were tested in a large multi-centric RA cohort in Egypt, consisting of 394 cases and 398 matched controls. Patients were stratified based on the positivity of either anti-citrullinated protein antibodies (ACPAs) or rheumatoid factor (RF). Significant association was evident for three SNPs in this cohort: the CD28 (rs1980422) variant showed a strong association in the whole cohort (P=0.000119) and in seropositive subsets of the disease (PACPA+=0.004; PRF+=0.0005). Upon stratification, the PTPN22 (rs2476601) and TNFAIP3(rs5029939) variants showed association only with ACPA positive (PACPA+=0.00573) and negative (PACPA-=0.00999) phenotypes, respectively. Our results suggest that CD28(rs1980422) and PTPN22(rs2476601) contribute to RA-susceptibility in Egyptians. Failure to replicate the association of PADI4(rs2240340)/(PADI4_94) in Egyptian RA patients provides further support for the notion that genetic architecture of RA is different in multiple populations of European, Asian, African, and Middle Eastern ancestries. Further investigation using large-scale studies is thus needed to maximize the power of genetic association. Copyright © 2016. Published by Elsevier Inc.

Substantial evidence has verified the Mediterranean diet’s (MedDiet) nutritional adequacy, long-term sustainability, and effectiveness for preventing hard clinical events from cardiovascular disease (CVD), as well as increasing longevity. This article includes a cumulative meta-analysis of prospective studies supporting a strong inverse association between closer adherence to the MedDiet and the incidence of hard clinical events of CVD. The MedDiet has become an increasingly popular topic of interest when focusing on overall food patterns rather than single nutrient intake, not only in Mediterranean countries, but also globally. However, several myths and misconceptions associated with the traditional Mediterranean diet should be clearly addressed and dispelled, particularly those that label as “Mediterranean” an eating pattern that is not in line with the traditional Mediterranean diet. The transferability of the traditional MedDiet to the non-Mediterranean populations is possible, but it requires a multitude of changes in dietary habits. New approaches for promoting healthy dietary behavior consistent with the MedDiet will offer healthful, sustainable, and practical strategies at all levels of public health. The following article presents practical resources and knowledge necessary for accomplishing these changes. PMID:29117146

2015-01-01

Full Text Available Studying ancient Egyptian tombs have long been an important source of information regarding many aspects of Egyptian religion. Walls of New Kingdom tombs are often decorated with plenty of painted religious scenes. While they were primarily private structures containing images selected by the person who expected to be housed there for eternity, the funerary monuments also reflect religious beliefs. While numerous researches focused on many of the religious scenes depicted on the walls of ancient Egyptian tombs, no one focused on the knife - holders' scenes. Hence, the current study focused on knife - holders scenes depicted on the walls of both royal and private tombs dating back to the New Kingdom at Thebes. The current study was undertaken to shed light on the meaning and the function of knife in Ancient Egypt. To study the role of the knife-holders in Ancient Egypt. To spot light on the actions and behaviors and locations of the knife-holders in Ancient Egyptian civilization. To spot light on the representations of the knife-holders on the walls of the ancient Egyptians tombs in the Valley of the Kings and Valley of the Queens as well as the private tombs at western Thebes. To focus on the shapes and positions of the Knife-holders in Ancient Egypt. To explain the difference between Knife - Holders and Demons. To achieve the objectives of the study, the required data were collected from periodicals, references presenting Knife Holders scenes. Preserving the scenes of knife - holders on the walls of the royal tombs in the Valley of the Kings and Valley of the Queens dating back to the New Kingdom as well as the private tombs at western Thebes that contributed to the interpretation of all the data gathered from literature. The preliminary results indicated that the term (Knife-Holders is an expression which indicates to tomb-guardians, demons or minor divinities. These minor deities were subordinate to the major gods and goddesses. They

The eastern Mediterranean is a hotspot of biological invasions. Numerous species of Indo-pacific origin have colonized the Mediterranean in recent times, including tropical symbiont-bearing foraminifera. Among these is the species Pararotalia calcariformata. Unlike other invasive foraminifera, this species was discovered only two decades ago and is restricted to the eastern Mediterranean coast. Combining ecological, genetic and physiological observations, we attempt to explain the recent invasion of this species in the Mediterranean Sea. Using morphological and genetic data, we confirm the species attribution to P. calcariformata McCulloch 1977 and identify its symbionts as a consortium of diatom species dominated by Minutocellus polymorphus. We document photosynthetic activity of its endosymbionts using Pulse Amplitude Modulated Fluorometry and test the effects of elevated temperatures on growth rates of asexual offspring. The culturing of asexual offspring for 120 days shows a 30-day period of rapid growth followed by a period of slower growth. A subsequent 48-day temperature sensitivity experiment indicates a similar developmental pathway and high growth rate at 28°C, whereas an almost complete inhibition of growth was observed at 20°C and 35°C. This indicates that the offspring of this species may have lower tolerance to cold temperatures than what would be expected for species native to the Mediterranean. We expand this hypothesis by applying a Species Distribution Model (SDM) based on modern occurrences in the Mediterranean using three environmental variables: irradiance, turbidity and yearly minimum temperature. The model reproduces the observed restricted distribution and indicates that the range of the species will drastically expand westwards under future global change scenarios. We conclude that P. calcariformata established a population in the Levant because of the recent warming in the region. In line with observations from other groups of organisms

Forming dense beds that provide the structural basis of a distinct ecosystem, the gorgonian Eunicella cavolini (Octocorallia) is an important species in the Mediterranean Sea. Despite the importance and prevalence of this temperate gorgonian, little is known about its microbial assemblage, although bacteria are well known to be important to hard and soft coral functioning. Here, we used massively parallel pyrosequencing of 16S rRNA genes to determine the composition and relative abundances of bacteria associated with E. cavolini collected from different depths at a site on the French Mediterranean coast. We found that whereas the bacterial assemblages of E. cavolini were distinct and less diverse than those of the surrounding water column, the water depth did not affect the bacterial assemblages of this gorgonian. Our data show that E. cavolini?s microbiome contains only a few shared species and that it is highly dominated by bacteria from the genus Endozoicomonas, a Gammaproteobacteria that is frequently found to associate with marine invertebrates.

Concentrations of Hg, Se, Cd, Cu, Zn, Fe, Mn and As, in kidney, liver, muscle and blubber from 7 specimens of Stenella coeruleoalba, stranded along the Israeli Mediterranean coast (IMC) from 2006 to 2011 (2011-series) were determined and compared to previous data on S. coeruleoalba from the IMC (2001-series). No differences were observed in essential and toxic elements concentrations, between the two series, except for hepatic Mn which was higher in the latter. Hg/Se molar ratios in blubber, kidney and liver increased linearly with log Hg concentrations, while muscle was more heterogenic in this respect. Means (±SD) of hepatic Hg concentrations (134±89 and 181±200mgkg(-1), from the 2011 and 2001 series, respectively) were similar to that found in 2007-2009 specimens from Spain, possibly reflecting the relatively high natural background levels of mercury in the Mediterranean Sea.

Plio-Pleistocene extinctions and immigration credit reflected in the size-frequency distribution of Mediterranean marine bivalves

Science.gov (United States)

Nawrot, Rafal; Zuschin, Martin; Chattopadhyay, Devapriya

2015-04-01

Following the opening of the Suez Canal hundreds of Red Sea species have entered the Mediterranean Sea making it a global hot spot of marine bioinvasion. With the ongoing influx of the subtropical and tropical alien species and increasing sea surface temperatures, the Mediterranean biota is currently gaining a more tropical character and increasingly becoming a mixture of faunal stocks with different evolutionary histories. This susceptibility to invasion was suggested to reflect the presence of an empty ecological space left after decimation of incumbent warm-water fauna during Plio-Pleistocene climate fluctuations. As molluscs are among the most prolific immigrants, we test this hypothesis using data on taxonomic composition and body size of Pliocene Mediterranean bivalves derived from the literature sources and museum collections. The Pliocene inter-specific size-frequency distribution (SFD) is strikingly similar to the SFDs of the Recent Red Sea bivalve fauna, in spite of different biogeographic provenance and the absence of true reef ecosystems in the Pliocene of the Mediterranean region. In contrast, body-size patterns in both assemblages are significantly different from the present-day Mediterranean fauna characterized by smaller median and modal size. Our preliminary results suggest that the distinct shape of the modern Mediterranean SFD may reflect the selective nature of the late Piacenzian - Galesian (Late Pliocene - Early Pleistocene) extinctions pulses related to the onset of the Northern Hemisphere glaciations. These extinctions affected almost 40% of Pliocene species and were biased towards large-bodied taxa. They were not followed by re-immigration of warm-water species owing to the isolation from the tropical Atlantic biota by the cold upwelling along the NW coasts of Africa. The resulting invasion credit (sensu Jackson & Sax, 2010) is currently being paid by the Red Sea bivalves colonizing the Mediterranean Sea through the Suez Canal. Successful

Experimental Inoculation of Egyptian Rousette Bats (Rousettus aegyptiacus with Viruses of the Ebolavirus and Marburgvirus Genera

Directory of Open Access Journals (Sweden)

Megan E.B. Jones

2015-06-01

Full Text Available The Egyptian rousette bat (Rousettus aegyptiacus is a natural reservoir for marburgviruses and a consistent source of virus spillover to humans. Cumulative evidence suggests various bat species may also transmit ebolaviruses. We investigated the susceptibility of Egyptian rousettes to each of the five known ebolaviruses (Sudan, Ebola, Bundibugyo, Taï Forest, and Reston, and compared findings with Marburg virus. In a pilot study, groups of four juvenile bats were inoculated with one of the ebolaviruses or Marburg virus. In ebolavirus groups, viral RNA tissue distribution was limited, and no bat became viremic. Sudan viral RNA was slightly more widespread, spurring a second, 15-day Sudan virus serial euthanasia study. Low levels of Sudan viral RNA disseminated to multiple tissues at early time points, but there was no viremia or shedding. In contrast, Marburg virus RNA was widely disseminated, with viremia, oral and rectal shedding, and antigen in spleen and liver. This is the first experimental infection study comparing tissue tropism, viral shedding, and clinical and pathologic effects of six different filoviruses in the Egyptian rousette, a known marburgvirus reservoir. Our results suggest Egyptian rousettes are unlikely sources for ebolaviruses in nature, and support a possible single filovirus—single reservoir host relationship.

Genetic drift evolution under vaccination pressure among H5N1 Egyptian isolates

Afifi Manal A

2011-06-01

Full Text Available Background The highly pathogenic H5N1 is a major avian pathogen that intensively affects the poultry industry in Egypt even in spite of the adoption of vaccination strategy. Antigenic drift is among the strategies the influenza virus uses to escape the immune system that might develop due to the pressure of extensive vaccination. H5N1 mutates in an intensified manner and is considered a potential candidate for the possible next pandemic with all the catastrophic consequences such an eventuality will entail. Methods H5N1 was isolated from the pooled organ samples of four different affected flocks in specific pathogen free embryonated chicken eggs (SPF-ECE. A reverse transcriptase polymerase chain reaction (RT-PCR was performed to the haemagglutingin and neuraminidase. Sequencing of the full length haemagglutingin was performed. Sequence analyses of the isolated strains were performed and compared to all available H5N1 from Egyptian human and avian strains in the flu database. Changes in the different amino acid that may be related to virus virulence, receptor affinity and epitope configuration were assigned and matched with all available Egyptian strains in the flu database. Results One out of the four strains was found to be related to the B2 Egyptian lineage, 2 were related to A1 lineage and the 4th was related to A2 lineage. Comparing data obtained from the current study by other available Egyptian H5N1 sequences remarkably demonstrates that amino acid changes in the immune escape variants are remarkably restricted to a limited number of locations on the HA molecule during antigenic drift. Molecular diversity in the HA gene, in relevance to different epitopes, were not found to follow a regular trend, suggesting abrupt cumulative sequence mutations. However a number of amino acids were found to be subjected to high mutation pressure. Conclusion The current data provides a comprehensive view of HA gene evolution among H5N1 subtype viruses in

The present work is a compilation of two tasks within the frame of the project ;Geomagnetic Survey & Detailed Geomagnetic Measurements within the Egyptian Territory; funded by the ;Science and Technology Development Fund agency (STDF);. The National Research Institute of Astronomy and Geophysics (NRIAG), has conducted a new extensive land geomagnetic survey that covers the whole Egyptian territory. The field measurements have been done at 3212 points along all the asphalted roads, defined tracks, and ill-defined tracks in Egypt; with total length of 11,586 km. In the present work, the measurements cover for the first time new areas as: the southern eastern borders of Egypt including Halayeb and Shlatin, the Quattara depresion in the western desert, and the new roads between Farafra and Baharia oasis. Also marine geomagnetic survey have been applied for the first time in Naser lake. Misallat and Abu-Simble geomagnetic observatories have been used to reduce the field data to the Epoch 2010. During the field measurements, whenever possible, the old stations occupied by the previous observers have been re-occupied to determine the secular variations at these points. The geomagnetic anomaly maps, the normal geomagnetic field maps with their corresponding secular variation maps, the normal geomagnetic field equations of the geomagnetic elements (EGRF) and their corresponding secular variations equations, are outlined. The anomalous sites, as discovered from the anomaly maps are, only, mentioned. In addition, a correlation between the International Geomagnetic Reference Field (IGRF) 2010.0 and the Egyptian Geomagnetic Reference Field (EGRF) 2010 is indicated.

1995-06-01

To determine the prevalence and risk factors of hepatitis C virus (HCV) infection among Egyptian blood donors, 188 consecutive adult blood donors from four hospitals and one temporary donor center located in Cairo, Egypt were evaluated. Sera were tested for HCV antibodies (anti-HCV) using second-generation enzyme-linked immunosorbent assay (ELISA) test kits. Sera that were repeatedly reactive by ELISA were further verified by a second-generation recombinant immunoblot assay (RIBA). Antibodies to HCV were detected by RIBA in 26.6% of the blood donors, which is higher than the 10-19% prevalence of antibody found in other studies of Egyptian blood donors. A history of selling blood (odds ratio [OR] = 12.1) and the use of illicit parenteral drugs (OR = 2.5) were significantly associated with anti-HCV seropositivity after controlling for age and gender. These data indicate that the use of illicit drugs may be one reason for high levels of reported HCV infection among Egyptian blood donors. These findings also indicate that Egyptian blood donors should be screened for anti-HCV and individuals who have a history of drug abuse should be deferred from donating blood.

In 2013, an airborne laser scan survey was conducted in the territory of the Ionian city of Kolophon near the western coast of modern Turkey as part of an archaeological survey project carried out by the Mimar Sinan University of Istanbul (Turkey) and the University of Vienna (Austria). Several light detection and ranging (LiDAR) studies have been carried out in the temperate climate zones of Europe, but only a few in Mediterranean landscapes. Our study is based on the first LiDAR survey carried out for an archaeological purpose in Turkey and one of the first in the Mediterranean that have been planned, measured and filtered especially for archaeological research questions. The interpretation of LiDAR data combined with ground-observations proved extremely useful for the detection and documentation of archaeological remains below Mediterranean evergreen vegetation and dense maquis. This article deals with the methodological aspects of interpreting LiDAR data, using the Kolophon data as a case study. We offer a discussion of the strengths and limitations of LiDAR as an archaeological remote sensing method and suggest a best practice model for interpreting LiDAR data in a Mediterranean context. © 2017 The Authors.

2005-01-01

Precipitated barium sulphate (Blank fixe) was prepared and evaluated as an extender pigment, making use of the naturally occurring Egyptian barytes ore. X-ray diffraction patterns, transmission electron microscope, thermal gravimetric analysis, color measurements, specific gravity, oil absorption, bulking value, bleed resistance, hydrogen ion concentration, permanence for light and heat and chemical resistance were different methods used for characterization and evaluation of the prepared pigment. Medium oil alkyd resin, melamine-alkyd and epoxy resin were used as different binding media for the application and testing of the prepared pigments as an extender- in some paint formulations, this was done in comparison with a commercial imported blank fixe sample and the Egyptian barytes ore that it was prepared from. It was found that; a white bright fine powder of precipitated barium sulfate could be successfully prepared from the locally abundant Egyptian barytes ore. It has a suitable properties as an extender pigment. Paints pigmented with blank fixe offered favourable rheological and protective properties exceeding that of the imported commercial sample and the ore that was prepared from

2017-11-25

Biochemical constituents and master elements (Pb, Cr, Cd, Fe, Cu, Zn, Hg, B, Al, SO 4 2- , Na, K, Li, Ca, Mg, and F) were investigated in six different seaweed species from Abu Qir Bay in the Egyptian Mediterranean Sea coast. The moisture level ranged from 30.26% in Corallina mediterranea to 77.57% in Padina boryana. On dry weight basis, the ash contents varied from 25.53% in Jania rubens to 88.84% in Sargassum wightii. The protein contents fluctuated from 8.26% in S. wightii to 28.01% in J. rubens. Enteromorpha linza showed the highest lipids (4.66%) and carbohydrate contents (78.95%), whereas C. mediterranea had the lowest lipid (0.5%), and carbohydrate contents (38.12%). Chlorophylls and carotenoid contents varied among the species. Total antioxidant capacity of the tested green seaweeds had the highest activities followed by brown and red seaweeds which had a similar trend of phenol and tannins contents. High reducing power was observed in all tested seaweeds extract except Ulva lactuca. Brown species had the highest amount of elements followed by red and green seaweeds. Notably, SO 4 2- recorded the highest level in the tested green species (108.05 mg/g dry weight (DW)). The Ca/Mg and K/Na ratios reflected highly significant difference between seaweed species. This study keeps an eye on 29 parameters and by applying stepwise multiple regression analysis, prospective equations have been set to describe the interactions between these parameters inside seaweeds. Accordingly, the tested seaweeds can be recommended as a source of healthy food with suitable ion quotient and estimated daily intake values.

Egyptian jojoba seeds newly cultivated in Ismailia desert in Egypt promoted us to determine its lipid components. Fatty alcohols, fatty acids, wax esters and sterols patterns were determined by capillary GLC whereas, tocopherols profile, isopropenoid alcohols and sterylglycosides were determined by HPLC. The Egyptian seeds are rich in wax esters (55 %) with fatty alcohols C20:1 and C22:1 as major components and amounted to 43.0 % and 45.6 % respectively followed by C24:1 and C18:1(9.6 % and 1.3 % respectively). The fatty acids profile showed that C20:1 is the major constituent (60 %) followed by C18:1 and C22:1 (14.5 and 11.8 % respectively) whereas C24:1 was present at low concentration amounted to 1.6 %. In addition, the Egyptian jojoba wax contained C18:2 fatty acid at a level of 8.7 %. Wax esters composition showed that the local wax had C42 and C40 esters as major components amounted to 51.1 and 30.1 % respectively. Also, it had C44 and C38 at reasonable amounts (10.0 and 6.3 % respectively). Whereas C36 and C46 were present at lower concentrations amounted to 1.4 and 1.1 respectively. The sterols analysis showed the presence of campe-, stigma-, beta-sito-, and isofuco- sterol amounting to 18.4 %, 6.9 %, 68.7 %, and 6.0 % respectively. The tocopherols pattern revealed that the local seed wax contained gamma-tocopherol as major constituent (79.2 %) followed by alpha-tocopherol (20.3 %). beta-tocopherol as well as delta-tocopherol were found as minor constituents. The isopropenoid alcohols and the sterylglycosides (free and acylated) were not detected. The wax is proposed to be used in oleo chemistry and cosmetics.

Khodayar, Samiro; Kalthoff, Norbert; Raff, Fritz

2013-04-01

Fall season heavy rainfall in the western Mediterranean region is one of the most threatening phenomena in the area. Devastating flash floods occur every year somewhere in eastern Spain resulting in a large amount of property losses, destruction of infrastructures, enormous agricultural losses and human fatalities. The forecast of the underlying HIW is a subject of special concern for local meteorologist because of its catastrophic nature. Within the framework of HyMeX (Hydrological cycle in the Mediterranean eXperiment) a HIW (High Impact Weather) event took place on the south and eastern part of the Spanish coast, particularly in Andalusia, Murcia, Valencia, Catalonia and less pronouncedly in the Balearic Islands, moving afterwards towards France southern coast. During this event casualties and important economic damage were registered. The amounts of precipitation locally overpassed 200 mm in 24 hours and a tornado occurred in Gandia (Valencia). The main objective of this work is to provide a comprehensive description of the physical atmospheric processes giving rise to the intense precipitation in this event and its movement along the Spanish coast. High-resolution COSMO-CLM model simulations supported by the analysis of observational data sets will be presented. The model simulations and observational data sets, such as a dense network of global positioning systems (GPS), raingauges, surface measurements and radiosoundings are analyzed to document in detail the evolution of the warm and wet air masses which fed the high precipitation event (HPE) systems, as well as the low-level convergence to which the main convective systems were associated.

Implementing a Mediterranean-Style Diet Outside the Mediterranean Region.

Science.gov (United States)

Murphy, Karen J; Parletta, Natalie

2018-05-04

Populations surrounding the Mediterranean basin have traditionally reaped health benefits from a Mediterranean diet (MedDiet), which may benefit Westernized countries plagued by chronic disease. But is it feasible to implement beyond the Mediterranean? To answer this question, we present evidence from randomized controlled trials that achieved high dietary compliance rates with subsequent physical and mental health benefits. In the 1960s, the Seven Countries Study identified dietary qualities of Mediterranean populations associated with healthy aging and longevity. The PREDIMED study confirmed reductions in CVD-related mortality with a MedDiet; a meta-analysis in over 4.7 million people showed reduced mortality, CVD-related mortality, and reduced risk of Parkinson's and Alzheimer's disease. Continually emerging research supports the MedDiet's benefits for chronic diseases including metabolic syndrome, cancers, liver disease, type 2 diabetes, depression, and anxiety. We summarize components of studies outside the Mediterranean that achieved high compliance to a Med-style diet: dietitian led, dietary education, goal setting, mindfulness; recipe books, meal plans, and food checklists; food hampers; regular contact between volunteers and staff through regular cooking classes; clinic visits; and recipes that are simple, palatable, and affordable. The next step is testing the MedDiet's feasibility in the community. Potential obstacles include access to dietetic/health care professionals, high meat intake, pervasive processed foods, and fast food outlets. For Western countries to promote a Med-style diet, collective support from government, key stakeholders and policy makers, food industry, retailers, and health professionals is needed to ensure the healthiest choice is the easiest choice.

This study compares postfire regeneration and diversity patterns in fire-prone chaparral shrublands from mediterranean (California) and non-mediterranean-type climates (Arizona). Vegetation sampling was conducted in tenth hectare plots with nested subplots for the first two years after fire. Floras in the two regions were compared with Jaccard's Index and importance of families and genera compared with dominance-diversity curves. Although there were 44 families in common between the two regions, the dominant families differed; Poaceae and Fabaceae in Arizona and Hydrophyllaceae and Rosaceae in California. Dominance diversity curves indicated in the first year a more equable distribution of families in Arizona than in California. Woody plants were much more dominant in the mediterranean climate and herbaceous plants more dominant in the bimodal rainfall climate. Species diversity was comparable in both regions at the lowest spatial scales but not at the tenth hectare scale. Due to the double growing season in the non-mediterranean region, the diversity for the first year comprised two different herbaceous floras in the fall and spring growing seasons. The Mediterranean climate in California, in contrast, had only a spring growing season and thus the total diversity for the first year was significantly greater in Arizona than in California for both annuals and herbaceous perennials. Chaparral in these two climate regimes share many dominant shrub species but the postfire communities are very different. Arizona chaparral has both a spring and fall growing season and these produce two very different postfire floras. When combined, the total annual diversity was substantially greater in Arizona chaparral.

Bibliographic and data gathered in scientific bottom trawl surveys carried out off the Southern Coasts of Sicily (Mediterranean Sea), from 1994 to 2009 and between a depth of 10 and 800 m, were analysed in order to prepare a checklist of demersal sharks and chimaera, which are species sensitive to fisheries exploitation. Out of the 27 previously reported demersal shark and chimaera taxa in the Mediterranean, only 23 were found in literature and 20 sampled during the surveys in the investigated area. Among the species sampled in the surveys, only 2 ubiquitous ( Squalus blainville and Scyliorhinus canicula ) and 3 deep-water ( Chimaera monstrosa , Centrophorus granulosus and Galeus melastomus ) species showed a wide geographical distribution with a consistent abundance. Excluding the rare (such as Oxynotus centrina ) or uncommon shark (e.g. Squalus acanthias ), the estimated frequencies of occurrence and abundance indexes show a possible risk of local extinction for the almost exclusively (e.g. angelshark, Squatina spp.) or preferential (e.g. Scyliorhinus stellaris ) neritic species.

Angiotensin-1-converting enzyme (ACE) is a crucial player in vascular homeostasis and in the pathogenesis of atherosclerosis and hypertension. The present study was conducted to determine whether there is an association between the ACE insertion/deletion (I/D) polymorphism and ischemic stroke in Egyptian population. Also, we analyzed the ACE gene I/D polymorphism as a risk factor for small-vessel (SV) versus large-vessel (LV) disease. Sixty patients with ischemic stroke were included: 30 with SV disease and 30 with LV disease. In addition, a control group of 30 apparent healthy subjects were studied. Clinical assessment, computed tomography, magnetic resonance imaging brain, and genetic study using the polymerase chain reaction of ACE gene were done for all subjects. We found that the distribution of ACE gene polymorphism frequency was significantly different between the 3 groups. The DD genotype was far more common in stroke patients compared to controls. It was also significantly more common in each of the patient groups compared to controls but rather similar in the 2 patient groups with SV and LV diseases. We found that the ACE gene deletion/deletion genotype is common in Egyptian patients with non-cardioembolic ischemic stroke but does not appear to be specific neither to SV nor to LV disease.

Phylogeography, historical demography and distribution modelling of freshwater fishes inhabiting seasonally fluctuating Mediterranean river systems: a case study using the Iberian cyprinid Squalius valentinus

Directory of Open Access Journals (Sweden)

Full Text Available The Mediterranean freshwater fish fauna has evolved under constraints imposed by the seasonal weather/hydrological patterns that define the Mediterranean climate. These conditions have influenced the genetic and demographic structure of aquatic communities since their origins in the Mid-Pliocene. Freshwater species in Mediterranean-type climates will likely constitute genetically well-differentiated populations as a consequence of fragmentation resulting from drought/flood cycles, to varying extents depending on basin size. We developed an integrative framework to study spatial patterns in genetic diversity, demographic trends, distribution modelling, and landscape genetics to evaluate the evolutionary response of Mediterranean-type freshwater fish to seasonal fluctuations in weather. To test this evolutionary response, the model species used was Squalius valentinus, an endemic cyprinid of the Spanish Levantine area, where seasonal weather fluctuations are extreme, although our findings may be extrapolated to other Mediterranean-type species. Our results underscore the significant role of the Mediterranean climate, along with Pleistocene glaciations, in diversification of S. valentinus. We found higher nuclear diversity in larger drainage basins, but higher mitochondrial diversity correlated to habitat suitability rather than basin size. We also found strong correlation between genetic structure and climatic factors associated with Mediterranean seasonality. Demographic and migration analyses suggested population expansion during glacial periods that also contributed to the current genetic structure of S. valentinus populations. The inferred species distribution models support the significant contribution of precipitation and isothermality for S. valentinus habitat suitability. We highlight the importance of stable habitat conditions, fostered by typical karstic springs found on the Mediterranean littoral coasts, for the preservation of

Little is known about the factors which might influence the adherence to a Mediterranean diet in non-Mediterranean European countries. Thus, the main purpose of this study was to determine the associations between socioeconomic, psychological, and physical factors on a Mediterranean diet. In this cross-sectional study, participants were 14-18-year-old adolescents ( N = 3071) from two non-Mediterranean countries: Lithuania ( N = 1863) and Serbia ( N = 1208). The dependent variable was Mediterranean diet, and was assessed with the Mediterranean Diet Quality Index for children and adolescents questionnaire. Independent variables were gender, body-mass index, self-rated health, socioeconomic status, psychological distress, physical activity, and sedentary behavior. The associations between dependent and independent variables were analyzed by using logistic regression. Results showed that higher adherence to a Mediterranean diet was associated with higher self-rated health, socioeconomic status, and physical activity, yet low adherence to a Mediterranean diet was associated with being female, having higher body-mass index, psychological distress, and sedentary behavior. Our findings suggest that future studies need to explore associations between lifestyle habits-especially in target populations, such as primary and secondary school students.

Octopus vulgaris (Cuvier, 1797) in the Mediterranean Sea: Genetic Diversity and Population Structure.

Science.gov (United States)

De Luca, Daniele; Catanese, Gaetano; Procaccini, Gabriele; Fiorito, Graziano

2016-01-01

The common octopus, Octopus vulgaris Cuvier 1797, is a largely exploited cephalopod species in the Mediterranean Sea and the Atlantic Ocean, as well as along the coasts of Africa, Brazil and Japan, where its taxonomic identity is still debated. The assessment of its genetic structure is a pressing need to correctly manage the resource and to avoid overfishing and collapsing of local stocks. Here we analysed genetic variation and population structure of O. vulgaris using thirteen microsatellite loci in seven sampling localities from the Mediterranean Sea and one from the Atlantic Ocean. We also used a DNA barcoding approach by COI gene fragment to understand the phylogenetic relationships among the specimens here investigated and the ones whose sequences are available in literature. Our results reveal high levels of allelic richness and moderate heterozygosity in all samples investigated, and a pronounced differentiation of the Atlantic and Sicilian specimens. This latter aspect seems to support the isolation of the biota within the Strait of Messina. A certain degree of differentiation was detected among the other geographic samples within the Mediterranean Sea, which is more compatible with an island model than isolation by distance. The occurrence of null alleles affected more genetic diversity indices than population structure estimations. This study provides new insights about the genetic diversity and structure of O. vulgaris in the area of interest, which can be used as guidelines for a fisheries management perspective.

The aim of the study was to provide a paleopathologic and radiologic overview of the jaws and teeth of 3 Egyptian mummies preserved in the Civic Museum of History and Art in Trieste. Computerized tomography (CT) imaging and postprocessing techniques were used to examine the oral structures. A 16-slice CT scanner was used (Aquilion 16; Toshiba Medical Systems Europe, Zoetermeer, The Netherlands). Scans were obtained at high resolution. Orthogonal-plane and 3-dimensional (3D) reconstructions were created along with curved reconstructions of the lower and upper jaws. Determination of decayed/missing teeth (DMT) and decayed/missing/tooth surfaces (DMTs) were made with 3D images. Analyses revealed differences in the embalming techniques and state of preservation of the bodies. Marked wear of the occlusal surfaces was a characteristic finding in all of the mummies. The DMT and DMTs were low compared with values for contemporary populations. Two mummies had fully erupted third molars. All mummies exhibited bone changes consistent with periodontitis. The CT evaluations of the oral structures of the mummies provided insight into the dental status and oral diseases of these ancient Egyptians. The low DMT and DMTs values and indications of periodontitis may be associated with the lifestyle of these Egyptians. The fully erupted and well aligned third molars may represent a morphologic adaptation of the arches to the muscular activity associated with grinding tough foods.

The Mariae species complex, consisting of Aedes mariae, Aedes phoeniciae, and Aedes zammitii, has a limited distribution worldwide. All three species are found in rocky habitats on the coastal areas of Mediterranean countries. Aedes phoeniciae and Ae. zammitii are two members of the Mariae complex that exist in Turkey. The aim of this study was to determine the distribution pattern and genetic structure of Ae. zammitii along the Mediterranean and Aegean regions. For this purpose, larval and adult samples of Ae. zammitii were collected from 19 different rocky habitats along the coastal regions of Antalya, Muğla, Aydın, İzmir, Balıkesir, and Çanakkale provinces. DNA isolation was performed primarily from collected samples, and mitochondrial NADH dehydrogenase 4 (ND4) gene was amplified by polymerase chain reaction. Based on ND4 sequence analyses, 21 haplotypes were detected along the distribution range of the species. Analyses of molecular variance (AMOVA) and spatial analyses of molecular variance (SAMOVA) indicated six groups, and most of the variation was among groups, demonstrating the population structuring at group level. Isolation by distance analyses (IBD) showed a correlation between geographic and genetic distances. © 2016 The Society for Vector Ecology.

Expression of therapeutic misconception amongst Egyptians: a qualitative pilot study.

Wazaify, Mayyada; Khalil, Susan S; Silverman, Henry J

2009-06-30

Studies have shown that research participants fail to appreciate the difference between research and medical care, labeling such phenomenon as a "therapeutic misconception" (TM). Since research activity involving human participants is increasing in the Middle East, qualitative research investigating aspects of TM is warranted. Our objective was to assess for the existence of therapeutic misconception amongst Egyptians. Study Tool: We developed a semi-structured interview guide to elicit the knowledge, attitudes, and perspectives of Egyptians regarding medical research. We recruited individuals from the outpatient settings (public and private) at Ain Shams University in Cairo, Egypt. Interviews were taped, transcribed, and translated. We analyzed the content of the transcribed text to identify the presence of a TM, defined in one of two ways: TM1 = inaccurate beliefs about how individualized care can be compromised by the procedures in the research and TM2 = inaccurate appraisal of benefit obtained from the research study. Our findings showed that a majority of participants (11/15) expressed inaccurate beliefs regarding the degree with which individualized care will be maintained in the research setting (TM1) and a smaller number of participants (5/15) manifested an unreasonable belief in the likelihood of benefits to be obtained from a research study (TM2). A total of 12 of the 15 participants were judged to have expressed a TM on either one of these bases. The presence of TM is not uncommon amongst Egyptian individuals. We recommend further qualitative studies investigating aspects of TM involving a larger sample size distinguished by different types of illnesses and socio-economic variables, as well as those who have and have not participated in clinical research.

2017-01-01

Full Text Available Social network platforms are tools, which are not just utilized for entertainment, but also serve as a multiple purposed tool in other areas, including politics. Egyptians have utilized these tools to communicate, coordinate, and bring about mass protests, since 2010. Drawing on the theoretical concepts of the public sphere and communicative action of Habermas, with the new public sphere and network society this paper examines the role of SNSs during the Arab Spring in Egypt. The lit review assumes that SNSs are causes of political upheavals. The article, however, argues that the SNSs are simply an instrument for communication and mobilization of people in the Egyptian 25th January political uprising.

The electrical properties of Egyptian natural graphite flakes, obtained from the graphite schists of Wadi Bent, Eastern Desert, were measured. The flakes were ground and compressed into pellets. The standard four probe dc method was used to measure the temperature dependence of the electric resistivity from room temperature down to 12 K. The transverse and longitudinal magnetoresistance were measured in the low magnetic field range at temperatures 300 K, 77 K and 12 K. The transverse magnetoresistance data was used to estimate the average mobility, assuming a simple two-band model. (author). 20 refs, 4 figs, 1 tab

Full Text Available Abstract Introduction Prune belly syndrome is a rare congenital anomaly of uncertain aetiology almost exclusive to males. The association between prune belly syndrome and Down syndrome is very rare. Case presentation A 4-month-old Egyptian boy was admitted to our institute for management of acute bronchiolitis. He was born at full term by normal vaginal delivery. His mother, a 42-year-Egyptian villager with six other children, had no antenatal or prenatal care. On examination, the boy was found to be hypotonic. In addition to features of Down syndrome, karyotyping confirmed the diagnosis of trisomy 21. Ultrasound examination of the abdomen showed bilateral gross hydronephrosis with megaureter. Micturating cystourethrography showed grade V vesicoureteric reflux bilaterally with no urethral obstruction. Serum creatinine concentration was 90 μmol/litre, serum sodium was 132 mmol/litre and serum potassium was 5.9 mmol/litre. Conclusion We report an Egyptian infant with Down syndrome and prune belly syndrome. The incidence of this association is unknown. Routine antenatal ultrasonography will help in discovering renal anomalies which can be followed postnatally. Postnatal detection of prune belly syndrome necessitates full radiological investigation to detect any renal anomalies. Early diagnosis of this syndrome and determining its optimal treatment are very important in helping to avoid its fatal course.

Hudson, William

2017-01-01

Background Egyptian Arabian horses have been maintained in a state of genetic isolation for over a hundred years. There is only limited genetic proof that the studbook records of female lines of Egyptian Arabian pedigrees are reliable. This study characterized the mitochondrial DNA (mtDNA) signatures of 126 horses representing 14 matrilines in the Egyptian Agricultural Organization (EAO) horse-breeding program. Findings Analysis of the whole D-loop sequence yielded additional information compared to hypervariable region-1 (HVR1) analysis alone, with 42 polymorphic sites representing ten haplotypes compared to 16 polymorphic sites representing nine haplotypes, respectively. Most EAO haplotypes belonged to ancient haplogroups, suggesting origin from a wide geographical area over many thousands of years, although one haplotype was novel. Conclusions Historical families share haplotypes and some individuals from different strains belonged to the same haplogroup: the classical EAO strain designation is not equivalent to modern monophyletic matrilineal groups. Phylogenetic inference showed that the foundation mares of the historical haplotypes were highly likely to have the same haplotypes as the animals studied (p > 0.998 in all cases), confirming the reliability of EAO studbook records and providing the opportunity for breeders to confirm the ancestry of their horses.

About 9% of the world's oil refining capacity is on the Mediterranean: some of the world's biggest and most advanced refineries are on Sicily and Sardinia. The Mediterranean refineries are important suppliers to southern Europe and N. Africa. The article discusses commercial refining in the Mediterranean under the headings of (i) historic development, (ii) product demand, (iii) refinery configurations, (iv) refined product trade, (v) financial performance and (vi) future outlook. Although some difficulties are foreseen, refining in the Mediterranean is likely to continue to be important well into the 21st century. (UK)

The occurrence and abundance of dinoflagellate cysts were investigated for the first time at an Ionian locality along the south-eastern coast of Sicily, subject to spring-summer harmful algal events. Thirty-four cyst morphotypes were recognized belonging to 24 taxa identified at least at the genus level. Cyst abundance in surface sediments ranged from 43 to 828 cysts g -1 dry weight, with the highest numbers recorded at the most restricted station. Germination experiments allowed confirmation of species identification determined by cyst analysis and provided clonal cultures of Alexandrium minutum and Gymnodinium nolleri, two of the bloom-forming species in the area. This represents the first record of G. nolleri for the Mediterranean Sea.

Knowledge of spatial patterns of genetic differentiation between populations is key to understanding processes in evolutionary history of biological species. Caulerpa is a genus of marine green algae, which has attracted much public attention, mainly because of the impacts of invasive species in the Mediterranean. However, very little is known about the ecological and evolutionary history of the Mediterranean native Caulerpa prolifera, a species which is currently found at sites distributed worldwide. C. prolifera provides a good model to explore the patterns of genetic diversity at different scales across the Mediterranean and Atlantic area. This study aims to investigate the biogeographical patterns of diversity and differentiation of C. prolifera in the Mediterranean, with special focus on the Mediterranean/Atlantic transition zone. We used two nuclear (ITS rDNA and the hypervariable microsatellite locus CaPr_J2) and one chloroplast (tufA) DNA markers on samples of C. prolifera from its entire range. Analyses of 51 sequences of the cpDNA tufA of C. prolifera, 87 ITS2 sequences and genotypes of 788 ramets of C. prolifera for the locus CaPr_J2 revealed three different biogeographical areas: West Atlantic, East Atlantic and a larger area representing the Mediterranean, the Mediterranean/Atlantic transition zone and a Pacific site (Bali). It was found out that the Mediterranean/Atlantic transition zone is a biogeographical boundary for C. prolifera. A lack of connectivity was revealed between Atlantic and Mediterranean types, and identical sequences found in the Mediterranean and Indo-Pacific suggest either recent gene flow along the Red Sea connection or a possible ancient Indo-Pacific origin.

2010-01-01

The concurrence and complementarities of obtained images under various wavelengths and the elemental and structural analyses provided by XRF and XRD, using portable non-invasive systems, have allowed for obtaining accurate data about the employed pictorial technique in two Egyptian wall paintings dating from the New Kingdom. Thus, compounds such as Egyptian blue, Egyptian green, goethite, jarosite, hematite, calcite, anhydrite or huntite have been detected in the paintings.

Hepatitis C virus genotype 4 (HCV-4) is spreading beyond Africa and the Middle East but data regarding treatment with pegylated interferon alpha and ribavirin of European populations infected with HCV-4 remains limited. Interestingly, European (vs. Egyptian) origin has been associated with lower sustained virological response rates. Hence the aim of this study was to investigate the treatment outcomes of Greek (vs. Egyptian), treatment-naïve patients infected with HCV-4 (subtype a) and to identify factors influencing response rates. One hundred seventy-seven consecutive patients (mean age: 44.6 ± 10.2, males: 143/177; 80.8%, Egyptians: 76/177; 42.9%) treated over a 7-year period at the Hepatology clinics of three tertiary care hospitals in Greece were retrospectively evaluated. Overall, sustained virological response was achieved in 75/177 (42.4%) of the cohort without a significant difference between the two ethnic groups [Greek: 44/101 (43.6%); Egyptian 31/76 (40.8%), P = 0.7598]. In multivariate analysis, it was found that ethnicity was not associated with an impaired response but age ≥45 years [odds ratio (OR): 0.4225, 95% confidence interval (CI): 0.2135-0.8133; P = 0.0134], diabetes (OR: 0.2346, 95% CI: 0.0816-0.0674; P = 0.0071), advanced liver fibrosis (OR: 0.3964, 95% CI: 0.1933-0.8133; P = 0.0116), and treatment suspension (OR: 0.1738, 95% CI: 0.0482-0.6262; P = 0.0075) showed an independent negative association with response to antiviral treatment. In contrast to previous European data suggesting Egyptian ethnicity to be a positive predictor for a sustained virological response, there was no influence of Greek versus Egyptian ethnicity on treatment outcomes. Higher age, advanced liver fibrosis, and diabetes have been shown to reduce significantly response rates in patients infected with HCV-4. Copyright © 2012 Wiley Periodicals, Inc.

M. BONACORSI

2013-03-01

Full Text Available Over the last few years, a widespread regression of Posidonia oceanica meadows has been noticed in the Mediterranean Sea. However, the magnitude of this decline is still debated. The objectives of this study are (i to assess the spatio-temporal evolution of Posidonia oceanica around Cap Corse (Corsica over time comparing available ancient maps (from 1960 with a new (2011 detailed map realized combining different techniques (aerial photographs, SSS, ROV, scuba diving; (ii evaluate the reliability of ancient maps; (iii discuss observed regression of the meadows in relation to human pressure along the 110 km of coast. Thus, the comparison with previous data shows that, apart from sites clearly identified with the actual evolution, there is a relative stability of the surfaces occupied by the seagrass Posidonia oceanica. The recorded differences seem more related to changes in mapping techniques. These results confirm that in areas characterized by a moderate anthropogenic impact, the Posidonia oceanica meadow has no significant regression and that the changes due to the evolution of mapping techniques are not negligible. However, others facts should be taken into account before extrapolating to the Mediterranean Sea (e.g. actually mapped surfaces and assessing the amplitude of the actual regression.

Benefits of the Mediterranean diet beyond the Mediterranean Sea and beyond food patterns.

Martínez-González, Miguel A

2016-10-14

Abundant and growing evidence has accrued to demonstrate that the traditional Mediterranean diet is likely to be the ideal dietary pattern for the prevention of cardiovascular disease. A landmark randomized trial (PREDIMED) together with many well-conducted long-term observational prospective cohort studies support this causal effect.A new, large British cohort study by Tong et al. assessing the association between adherence to the Mediterranean diet and cardiovascular disease was recently published in BMC Medicine. Using a superb methodology, they followed-up 23,902 participants for 12.2 years on average and observed several thousand incident cases.The results of this cohort study showed a significant beneficial effect of the Mediterranean diet on cardiovascular events. These findings support the transferability of this dietary pattern beyond the shores of the Mediterranean Sea. The authors provided measures of population impact in cardiovascular prevention and estimated that 19,375 cases of cardiovascular death would be prevented each year in the UK by promoting the Mediterranean Diet.Please see related article: http://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-016-0677-4 .

Deciphering Egyptian Hieroglyphs: Towards a New Strategy for Navigation in Museums

Directory of Open Access Journals (Sweden)

Jaime Duque-Domingo

2017-03-01

Full Text Available This work presents a novel strategy to decipher fragments of Egyptian cartouches identifying the hieroglyphs of which they are composed. A cartouche is a drawing, usually inside an oval, that encloses a group of hieroglyphs representing the name of a monarch. Aiming to identify these drawings, the proposed method is based on several techniques frequently used in computer vision and consists of three main stages: first, a picture of the cartouche is taken as input and its contour is localized. In the second stage, each hieroglyph is individually extracted and identified. Finally, the cartouche is interpreted: the sequence of the hieroglyphs is established according to a previously generated benchmark. This sequence corresponds to the name of the king. Although this method was initially conceived to deal with both high and low relief writing in stone, it can be also applied to painted hieroglyphs. This approach is not affected by variable lighting conditions, or the intensity and the completeness of the objects. This proposal has been tested on images obtained from the Abydos King List and other Egyptian monuments and archaeological excavations. The promising results give new possibilities to recognize hieroglyphs, opening a new way to decipher longer texts and inscriptions, being particularly useful in museums and Egyptian environments. Additionally, devices used for acquiring visual information from cartouches (i.e., smartphones, can be part of a navigation system for museums where users are located in indoor environments by means of the combination of WiFi Positioning Systems (WPS and depth cameras, as unveiled at the end of the document.

2011-11-01

Full Text Available Abstract Background Autism is a biological disorder with clearly defined phenomenology. Studies from the Middle East on this topic have been particularly rare. Little is known about the influence of culture on clinical features, presentations and management of autism. The current study was done to compare characteristics of autism in two groups of Egyptian as well as Saudi children. Methods The sample included 48 children with Autism Spectrum Disorder. They were recruited from the Okasha Institute of Psychiatry, Ain Shams University, Cairo, Egypt and Al-Amal Complex for Mental Health, Dammam, Kingdom of Saudi Arabia. They were grouped into an Egyptian group (n = 20 and a Saudi group (n = 28. They were assessed both clinically and psychometrically using the GARS, the Vineland adaptive behavioral scale, and the Stanford Binnet IQ test. Results Typical autism was more prevalent than atypical autism in both groups. There were no statistically significant differences in clinical variables like regression, hyperactivity, epilepsy or mental retardation. Delayed language development was significantly higher in the Egyptian group while delay in all developmental milestones was more significant in the Saudi group. The Vineland communication subscale showed more significant severe and profound communication defects in the Saudi group while the Gilliam developmental subscale showed significantly more average scores in the Egyptian group. Both groups differed significantly such that the age of noticing abnormality was younger in the Saudi group. The age at diagnosis and at the commencement of intervention was lower in the Egyptian group. The Saudi group showed a higher percentage of missing examinations, older birth order and significantly higher preference to drug treatment, while the Egyptian group showed a high preference to behavioral and phoniatric therapies, higher paternal and maternal education, higher employment among parents and higher family

Full Text Available Familial Mediterranean Fever is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. It affects the populations from Mediterranean basin. Genetic mutation of the disease is on MEFV gene located on short arm of Chromosome 16. The disease is diagnosed based on clinical evaluation. Amyloidosis is the most important complication. The only agent that decreases the development of amyloidosis and the frequency and severity of the episodes is colchicine, which has been used for about 40 years. In this review, we aimed to discuss especially the most recent advances about Familial Mediterranean Fever which is commonly seen in our population.

Vitamin D deficiency is becoming endemic in many parts of the world. To study vitamin D status in Egyptian females of different age groups. A cross-sectional study was conducted on 404 females, who were categorized into group 1 (51 nursing females); group 2 (50 pregnant females); group 3 (208 females of childbearing age); group 4 (38 elderly females); and group 5 (57 geriatric females). Females completed a questionnaire regarding dietary calcium and vitamin D intake, sun exposure, and clothing habits, and performed laboratory tests including calcium, PO4, alkaline phosphatase, intact PTH, and 25-OH vitamin D levels. Median and IQR of vitamin D levels across groups 1, 2, 3 and 5 were in the deficient range, being lowest in groups 3, 5, and 1, respectively. Vitamin D deficiency was found in 72.6% of the nursing group, 54% of the pregnant group, 72% of the childbearing age group, 39.5% of the elderly group, and 77.2% of the geriatric group. Vitamin D was significantly higher in non-veiled females [23ng/dl] as compared to veiled females [16.7ng/dl]. Vitamin D levels with poor, fair, and good sun exposure were 14.1, 14, and 37ng/dl, respectively. These results show a high prevalence of vitamin D deficiency among healthy Egyptian females.

Mediterranean coastal dune systems: Which abiotic factors have the most influence on plant communities?

Science.gov (United States)

Ruocco, Matteo; Bertoni, Duccio; Sarti, Giovanni; Ciccarelli, Daniela

2014-08-01

Mediterranean coastal dunes are dynamic and heterogeneous ecosystems characterised by a strong interaction between abiotic and biotic factors. The present study aimed to adopt a multidisciplinary approach - integrating data on dune morphology, sediment texture and soil parameters as well as shoreline trend - in order to define which are the abiotic factors that most affect the distribution and composition of Mediterranean plant dune communities. The study was carried out in two protected areas, located in central Italy, subjected to different shoreline trends in recent years. 75 plots were identified along eleven randomly positioned cross-shore transects, starting from the beach continuing up to the plant communities of the backdunes. In each plot floristic and environmental data - such as distance to the coastline, plot altitude, inclination, shoreline trend, mean grain-size, sorting, pH, conductivity and organic matter concentration - were collected. The analyses revealed significant changes of vegetational cover, dune morphology and geopedological features along the coast-to-inland gradient. Relationships between vegetation composition and environmental factors were investigated through Canonical Correspondence Analysis (CCA). Four factors - distance to the coastline, mean grain-size, shoreline trend and organic matter - were found to be closely correlated with the floristic composition of plant communities. Finally, soil properties were highlighted as the most determinant factors of community zonation in these Mediterranean coastal dune ecosystems. These results could be taken into account by local managers in conservation actions such as protecting the eroding foredunes as well as in artificial dune reconstructions.

2018-06-01

Full Text Available Egyptian chickens, representing 2 breeds and 7 strains, were genotyped using the PCR-RFLP and sequencing techniques for detection of a non-synonymous dimorphism (G/A in exon 14 of chicken Myxovirus resistance (Mx gene. This dimorphic position is responsible for altering Mx protein’s antiviral activity. Polymerase Chain reactions were performed using Egyptian chickens DNA and specific primer set to amplify Mx DNA fragments of 299 or 301 bp, containing the dimorphic position. Amplicons were cut with restriction enzyme Hpy81. Genotype and allele frequencies for the resistant allele A and sensitive allele G were calculated in all the tested chickens. Results of PCR-RFLP were confirmed by sequencing. The three genotypes AA, AG, GG at the target nucleotide position in Mx gene were represented in all the studied Egyptian chicken breeds and strains except Baladi strain which showed only one genotype AA. The average allele frequency of the resistant A allele in the tested birds (0.67 was higher than the sensitive G allele average frequency in the same birds (0.33. Appling PCR-RFLP technique in the breeding program can be used to select chickens carrying the A allele with high frequencies. This will help in improving poultry breeding in Egypt by producing infectious disease-resistant chickens. Keywords: Egyptian chickens, Antiviral activity, Mx gene, Genotyping, PCR-RFLP

In the present work, radioactivity has been studied in several Mollusca collected from four selected sites(Al Basset, Lattakia, Banise and Tartous) along the Syrian coast. Concentration Factors (CF) of radionuclides (Lead-210, Polonium-210, Uranium Isotopes, Potassium-40 and Cesium-137) in mussels and shells of Mollusca have been calculated in order to determine the species that could be used as Bioindicators for these isotopes. Statistical analysis of the results using the box plot method showed that the mussels of Spondylus spinosus and Chama pacifica can be used as biomonitor for the studied radionuclides in addition to shell of Strombus persicus and Spondylus spinosus. While the mussels of Brachidonta variabilis and Spondylus spinosus have shown good selectivity for Cd and Pb and Pinctada radiate for Zn and Thais haemostoma for Cu. In addition, the migrant Mullusca from the Red Sea, Strombus persicus, can be used as biomonitor for lead, Zn and Cu, Cd, while the shell of Thais haemostoma for lead. However, the importance of the results of the present study that are considered as a baseline data for radionuclides in Mullusca distributed along the Syria coast and it is the only study in the eastern Mediterranean basin, that defined the Mollusca species which could be use as biomonitors for radionuclides.

2006-01-01

The analyses of pigments originating from well dated ancient boat models found in Egyptian graves were used for characterization and for dating tasks of unknown objects. A nearly destruction free sampling technique using cotton buds was applied for sampling these valuable artifacts for a subsequent Total Reflection X-Ray Fluorescence Spectrometry (TXRF) analysis. Two relevant collections of Egyptian object of art were at our disposal, one of the Agyptisches Museum Berlin and the second of the British Museum London. Three groups of colors were studied, they originate from white, red and blue/green paints, respectively. The results of the analyses performed on micro-amounts of paints (< 1 μg) show that some artifacts were misclassified and belong to other epochs. Some others were retouched with modern colors. In general, it can be stated that results obtained by Total Reflection X-Ray Fluorescence Spectrometry may dissipate some uncertainties when applying classical archaeological dating methods

Zaqoot, Hossam Adel; Ansari, Abdul Khalique; Unar, Mukhtiar Ali; Khan, Shaukat Hyat

2009-01-01

Artificial Neural Networks (ANNs) are flexible tools which are being used increasingly to predict and forecast water resources variables. The human activities in areas surrounding enclosed and semi-enclosed seas such as the Mediterranean Sea always produce in the long term a strong environmental impact in the form of coastal and marine degradation. The presence of dissolved oxygen is essential for the survival of most organisms in the water bodies. This paper is concerned with the use of ANNs - Multilayer Perceptron (MLP) and Radial Basis Function neural networks for predicting the next fortnight's dissolved oxygen concentrations in the Mediterranean Sea water along Gaza. MLP and Radial Basis Function (RBF) neural networks are trained and developed with reference to five important oceanographic variables including water temperature, wind velocity, turbidity, pH and conductivity. These variables are considered as inputs of the network. The data sets used in this study consist of four years and collected from nine locations along Gaza coast. The network performance has been tested with different data sets and the results show satisfactory performance. Prediction results prove that neural network approach has good adaptability and extensive applicability for modelling the dissolved oxygen in the Mediterranean Sea along Gaza. We hope that the established model will help in assisting the local authorities in developing plans and policies to reduce the pollution along Gaza coastal waters to acceptable levels.

Global warming enhances sulphide stress in a key seagrass species (NW Mediterranean).

Science.gov (United States)

García, Rosa; Holmer, Marianne; Duarte, Carlos M; Marbà, Núria

2013-12-01

The build-up of sulphide concentrations in sediments, resulting from high inputs of organic matter and the mineralization through sulphate reduction, can be lethal to the benthos. Sulphate reduction is temperature dependent, thus global warming may contribute to even higher sulphide concentrations and benthos mortality. The seagrass Posidonia oceanica is very sensitive to sulphide stress. Hence, if concentrations build up with global warming, this key Mediterranean species could be seriously endangered. An 8-year monitoring of daily seawater temperature, the sulphur isotopic signatures of water (δ(34)S(water)), sediment (δ(34)SCRS ) and P. oceanica leaf tissue (δ(34)S(leaves)), along with total sulphur in leaves (TS(leaves)) and annual net population growth along the coast of the Balearic archipelago (Western Mediterranean) allowed us to determine if warming triggers P. oceanica sulphide stress and constrains seagrass survival. From the isotopic S signatures, we estimated sulphide intrusion into the leaves (F(sulphide)) and sulphur incorporation into the leaves from sedimentary sulphides (SS(leaves)). We observed lower δ(34)S(leaves), higher F(sulphide) and SS(leaves) coinciding with a 6-year period when two heat waves were recorded. Warming triggered sulphide stress as evidenced by the negative temperature dependence of δ(34)S(leaves) and the positive one of F(sulphide), TS(leaves) and SS(leaves). Lower P. oceanica net population growth rates were directly related to higher contents of TS(leaves). At equivalent annual maximum sea surface water temperature (SST(max)), deep meadows were less affected by sulphide intrusion than shallow ones. Thus, water depth acts as a protecting mechanism against sulphide intrusion. However, water depth would be insufficient to buffer seagrass sulphide stress triggered by Mediterranean seawater summer temperatures projected for the end of the 21st century even under scenarios of moderate greenhouse gas emissions, A1B

Georgoulis, Michael; Kontogianni, Meropi D.; Yiannakouris, Nikos

2014-01-01

The aim of the present review is to examine current scientific knowledge on the association between the Mediterranean diet and diabetes mellitus (mostly type 2 diabetes). A definition of the Mediterranean diet and the tools widely used to evaluate adherence to this traditional diet (Mediterranean diet indices) are briefly presented. The review focuses on epidemiological data linking adherence to the Mediterranean diet with the risk of diabetes development, as well as evidence from interventional studies assessing the effect of the Mediterranean diet on diabetes control and the management of diabetes-related complications. The above mentioned data are explored on the basis of evaluating the Mediterranean diet as a whole dietary pattern, rather than focusing on the effect of its individual components. Possible protective mechanisms of the Mediterranean diet against diabetes are also briefly discussed. PMID:24714352

Arbuscular mycorrhizal fungi associated with psammophilic vegetation in Mediterranean coastal sand dunes

Camprubi, A.; Calvet, C.; Cabot, P.; Pitet, M.; Estaun, V.

2010-07-01

This study was conducted in order to characterize the natural albacore's mycorrhizal (AM) biodiversity from Mediterranean sand dune ecosystems and to protect in a collection this biodiversity. The occurrence of AM fungi associated with sand dune plant species in three Mediterranean locations on the north-eastern coast of Spain was examined in one well preserved coastal sand dune and in two embrionary dunes recently protected from public access. Traditional taxonomy and molecular techniques were used to identify the AM fungal species present in these ecosystems. The species identified and isolated were: Scutellospora persica (Kiosk and Walker) Walker and Sanders, Glomus ambisporum Smith and Schenck, Glomus diaphanum Morton and Walker, Glomus clarum Nicolson and Schenck, Glomus intraradices Schenck and Smith, Glomus microaggregatum Koske, Gemma and Olexia and Gigaspora margarita Becker and Hall. Spores of Glomus were the most abundant in the direct soil extraction samples. The molecular analysis indicates that the most abundant fungi forming AM in the roots belonged to the Gigasporaceae group followed by fungi of Glomus group A and Glomus group B. The highest diversity of fungi and abundance of the AM fungal spores was found in the well preserved and undisturbed dune systems. (Author) 26 refs.

Full Text Available This study aims to measure the gap between the administration and the beneficiaries of the quality of the service in the federation and sport regions of Karate. The sample of this study was chosen randomly between the members of the board of directors of the Federation and regions, the coaches , referees and players registered in theEgyptian Federation of Karate whose numbers are (149. The sample of the study was classified into two beneficiary classes. The first beneficiary class is coaches and referees whose number are (70 persons and their administration is the members of the board of directors of the Federation and its regions whose number are (14persons. The second class is the players whose number are (65 players and their administration is the members ofthe board of directors of the Federation and its regions the referees and coaches' number are (84 persons. This study used a questionnaire (SERVQUAL to measure the quality of the service. Results pointed to a negative gap between the expectations of the beneficiaries of the excellent service level and the perceptions of the administrations of these expectations.These results refer to the weakness of administration ability in the Egyptian Federation of Karate to know the needs and desires of beneficiaries from (coaches-referees- players of the quality level in the service provided to them. The existence of a relative gap between the perceptions of the beneficiaries of the service actually provided and the administration of the qualities of the service actually provided, therefore itrefers to the decline the motive level of the administration of Egyptian Federation of Karate to provide the service to the beneficiaries in a form that conforms with what the administration already decided for the specifications. The existence of a negative gap between the expectations of the beneficiaries of the level of theexcellent service and its perception of the actual performance of this service refers to

Full Text Available The purpose of this study was to investigate the relationships between employee perception of equity and job satisfaction in the Egyptian private universities. Data were gathered using a face-to-face survey of 80 teaching staff members at three Egyptian universities. Findings revealed positive relationships between perceptions of equity, where a "motivator" was the outcome in the comparison, and job satisfaction. The study also revealed that there was no relationship between perceptions of equity and job satisfaction where a "hygiene factor" was the outcome in the comparison. This study is exploratory and findings are not conclusive. Its implications and limitations are discussed.

The palmaris longus (PL) is one of the most variable muscles in the human body. Racial differences in its variation have been documented. Several studies have attempted to correlate PL absence with other anatomical variations. This study was conducted to determine the prevalence of absence of PL, correlate it with gender and body side and to determine its association with other anatomical variations in the Egyptian population. The presence of PL was clinically determined in 386 Egyptians using the standard technique. All subjects were examined for the presence of the flexor digitorum superficialis (FDS) to the fifth finger. Allen's test was done to assess the completeness of the superficial palmar arch (SPA). The overall prevalence of absence of the PL in Egyptian subjects was 50.8%. There was no significant difference in PL absence with regard to the body side but a significant difference was seen as regards gender and when bilateral absence of PL was compared to its unilateral absence. Absence of FDS tendon to the fifth finger was seen in 1.3% subjects. There was no association between the absence of the FDS tendon to the fifth finger and either presence or absence of PL and also between the absence of PL and the incompleteness of SPA in both genders. In conclusion, the prevalence of absence of PL in the Egyptian population represents one of the highest rates of absence to be reported for this muscle, which is significantly different from that in other ethnic groups.

Erosion and Land Degradation in Mediterranean areas as a adaptive response to Mediterranean agriiculture

Science.gov (United States)

Imeson, Anton

2014-05-01

The motivation for this session is the statement or claim that Mediterranean areas are sensitive to erosion and desertification. One result of the LEDDRA Approach, which is applying the Complex Adaptive (CAS)paradigm at study sites in Mediterranean Spain, Greece and Italy is that there is just a single socio-environmental system in which land degradation is being caused by the actions of people and the Mediterranean soils have co-eveolved with people under the influence of fire and grazing. They are therefore resilient, and this was demonstrated by Naveh and Thornes. Also the Medalus field sites showed very low rates of erosion. With examples from different Mediterranean landscapes, it is considered that Mediterranean landscapes went through an initial phase of being sensitive to erosion which ended up with the original soils before ploughing or deforestation, being eroded from most of the areas, In some places these are found. LEDDRA The Leddra approach is to consider different states which are separated by transitions. The first state is that of the deforestaion and destruction of the forest that took place 6000 10000 years ago, in the Eastern and Northern Mediterranean, and 2000 to 4,000 years ago in large areas of the Western Mediterranean, and 100 to 400 years ago in California. Australia, New Zealand and Chile. The second state involves appropriating and settling the land from indigenous people and introducing cattle and sheep and Mediterranean crops. The current state of desertification is one in which erosion occurs because of the use of specific cultivation methods and subsidies for irrigating and producing crops outside of their range. In the Mediterranean landscape State, such as found near Santiago in Chile and in Crete, society gains many cultural benefits from grazing. However, the consequences of this are that the whole ecosystem is maintained in an arid state, so that areas in Crete receiving 800-1100 mm rainfall have a semi arid vegetation, instead

Coal in the Mediterranean

International Nuclear Information System (INIS)

Sore, J.C.; Coiffard, J.

1992-01-01

Mediterranean countries are not traditionally coal producers. In France, the main mines were located in the North and East, and belonged to the great coal fields of northern Europe. Spain is a modest producer (ten million tonnes), as is Turkey with its three million tonnes. The only way most of these mines can stand up to international competition is by an array of protectionistic measures and subsidies. This state of affairs has marked events of quite another nature, as it relates to energy economics. That is, coal has taken on increasing importance in the energy supplies of all the countries of the Mediterranean zone over the past twenty years. In this article, we set out by describing coke supply for the Mediterranean ensemble, and then go on to analyze the development aspects of coal for electrical production, the future of Mediterranean lignite, and the supply of imported coal. 4 refs., 11 figs., 3 tabs

The Mediterranean Basin atmosphere is influenced by both strong natural and anthropogenic aerosol emissions and is also subject to important climatic forcings. Several programs have addressed the study of the Mediterranean basin; nevertheless important pieces of information are still missing. In this framework, PM10 samples were collected on a daily basis on the island of Lampedusa (35.5° N, 12.6° E; 45 m a.s.l.), which is far from continental pollution sources (the nearest coast, in Tunisia, is more than 100 km away). After mass gravimetric measurements, different portions of the samples were analyzed to determine the ionic content by ion chromatography (IC), the soluble metals by inductively coupled plasma atomic emission spectrometry (ICP-AES), and the total (soluble + insoluble) elemental composition by particle-induced x-ray emission (PIXE). Data from 2007 and 2008 are used in this study. The Positive Matrix Factorization (PMF) model was applied to the 2-year long data set of PM10 mass concentration and chemical composition to assess the aerosol sources affecting the central Mediterranean basin. Seven sources were resolved: sea salt, mineral dust, biogenic emissions, primary particulate ship emissions, secondary sulfate, secondary nitrate, and combustion emissions. Source contributions to the total PM10 mass were estimated to be about 40 % for sea salt, around 25 % for mineral dust, 10 % each for secondary nitrate and secondary sulfate, and 5 % each for primary particulate ship emissions, biogenic emissions, and combustion emissions. Large variations in absolute and relative contributions are found and appear to depend on the season and on transport episodes. In addition, the secondary sulfate due to ship emissions was estimated and found to contribute by about one-third to the total sulfate mass. Results for the sea-salt and mineral dust sources were compared with estimates of the same contributions obtained from independent approaches, leading to an

Full Text Available Background. Children who drink too little to meet their daily water requirements are likely to become dehydrated, and even mild dehydration can negatively affect health. This is even more important in Middle-Eastern countries where high temperatures increase the risk of dehydration. We assessed morning hydration status in a sample of 519 Egyptian schoolchildren (9-11 years old. Methods. Children completed a questionnaire on breakfast intakes and collected a urine sample after breakfast. Breakfast food and fluid nutritional composition was analyzed and urine osmolality was measured using osmometry. Results. The mean urine osmolality of children was 814 mOsmol/kg: >800 mOsmol/kg (57% and >1000 mOsmol/kg (24.7%. Furthermore, the results showed that a total water intake of less than 400 mL was associated with a significant higher risk of dehydration. Surprisingly, 63% of the children skipped breakfast. Conclusions. The results showed that a majority of Egyptian schoolchildren arrive at school with a hydration deficit. These results highlight the fact that there is a need to educate schoolchildren about the importance of having a breakfast and adequate hydration.

The global health community faces a challenge with breast cancer being the most common cause of cancer related death among women around the globe. Since breast cancer’s pathogenesis is poorly understood, primary prevention is still a distant goal. Thus secondary prevention through early detection is the only feasible approach at present. With this strong conviction, the launching o f the first Egyptian national screening program W omen Health Outreach Program ( WHOP), was announced on October 30 th 2007. This project is a government- funded program that offers free breast screening for all Egyptian women above the age of 45 years. In addition to free mammograms, the program gives the participants a chance to be screened for diabetes, hypertension and obesity as well. Positively detected cases are also offered the option of free management. During the period from October 30 th , 2007, up to February 9 th , 2009, 20, 098 women in Cairo, Alexandria and Suez governorates were screened for breast cancer, diabetes, hypertension and obesity through the program. In this article we will represent the achievements, challenges and services delivered by WHOP

2003-01-01

Eight different types of food items, collected from eight Egyptian governorates, were subjected to elemental analysis to determine Ni, Al, and Sr concentration by using Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES). The result indicated that the concentration of Ni, Al and Sr are in range of 0.04-7.31, 0.07-5.56, 0.02-13.4 mg/kg-wet weight respectively. The maximum concentrations of Ni and Al are present in cereals and leafy vegetables while minimum values are present in roots and tubers. Sr concentration showed completely different trend. Its maximum value is present in fish samples. This focuses a very important remark about its active pathway (aquatic ecosystem) to prevent completely the disposal of radioactive Sr in any water body.By knowing the food consumption values by Egyptian, the daily dietary intake of these elements were calculated. The obtained mean values are 1.894, 2.242 and 1.483 mg/d/caput for Ni, Al and Sr respectively. These values are within the reported data and far away from their toxic intake level

Ahmed, Sahar; Grobler, Paul; Madisha, Thabang; Kotze, Antionette

2017-09-01

The mitochondrial D-loop region was used to investigate genetic diversity within and between populations of Egyptian goats, to elucidate processes that explain present patterns of diversity and differentiation and to characterize Egyptian goats relative to international breeds. A total of 120 animals from six populations were sampled. Results confirm the main trend from previous studies of mtDNA diversity in goats, with high levels of diversity within populations, but with a comparative lack of genetic structure supporting geographic distribution. Haplotype diversity varied in a narrow range whereas nucleotide diversity values were more informative in showing differences between populations. The majority of goats analyzed (93.2%) displayed haplotypes that group with Haplogroup A, the most common type found in global goat populations. The remaining animals grouped with the less common Haplogroup G. Population differentiation analysis showed some uniqueness in the Aswan and Sharkawi populations from the South and East of Egypt. Overall, the structure of the Egyptian goat population is characterized by a high degree of homogeneity among populations from the north-western coastal region, the Nile Delta and the upper and middle regions of the Nile valley, but with possible introgression of rarer haplotypes into populations at the southern and eastern extremities of the country.

We investigated SIRT-1 genetic variant and its association with vitamin D level in Egyptian patients with rheumatoid arthritis (RA). Seventy Egyptian subjects were enrolled in our study and divided into two groups: RA group (n = 50 patients) and healthy control group (n = 20 subjects). Five milliliter blood sample was withdrawn from each subject followed by laboratory investigation and DNA extraction for SIRT-1 gene polymorphism assessment (rs7895833 A>G, rs7069102 C>G and rs2273773 C>T) and vitamin D level expression. There was statistically significant difference between rheumatoid cases and controls with regard to vitamin D level with 88% of cases showing insufficient vitamin D versus all controls showing sufficient level. SIRT-1 different SNPs rs2273773, rs7895833and rs7069102 genotype frequencies were statistically significant in RA compared to control group (P = 0.001). There was no statistically significant difference between different genotypes of rs2273773, rs7895833 and rs7069102 with regard to vitamin D level. We concluded that there is a strong association between SIRT-1 polymorphism genotyping and RA. Vitamin D level was insufficient in Egyptian patients with RA.

Full Text Available Objective: To present the first information on the feeding habits of the Mediterranean needlefish Tylosurus acus imperialis (T. a. imperialis of Tunisia and to examine the diet variation in relation to the fish size, maturity and sex. Methods: Gut contents of 92 specimens of T. a. imperialis, collected mainly from May 2004 to July 2006 off the Gulf of Gabès, Southeastern Tunisian coast, were analyzed. Results: The results showed that 55.4% of them had empty guts and 44.6% contained food in their guts. The emptiness index did not vary significantly according to size classes or sexes of T. a. imperialis. Basic food consisted of teleosts (Mugilidae, Gobidae and Belonidae (62.6% followed by crustaceans (37.3%, mostly decapods Sycionia carinata (5.4%. A decrease in the feeding rate at the peak of the spawning season was observed for both sexes. A diet variation among juvenile and adult specimens of T. a. imperialis was found. Conclusions: This study enhances our knowledge on the biology of the Mediterranean needlefish T. a. imperialis. This fish is an active predator and an opportunistic feeder but the feeding rate declines at the peak of the spawning season.

This essay looks at acts of hospitality and revenge as constituent elements of a broad social code in rural Egyptian narratives. By looking at five stories in particular, I argue that hospitality and revenge work in complementarity, and that they often trespass and blur each other’s social and literary borders, creating ambiguity and complexity in the stories. The traditional rules that govern hospitality are at times challenged or inverted by hostile intentions, and revenge may be exacted fo...

2008-01-01

In the present work, radioactivity has been studied in several Mollusca collected from four selected sites (Al Basset, Latakia, Banise and Tartous) along the Syrian coast. Concentration Factors (CF) of radionuclides (Lead-210, Polonium-210, Uranium Isotopes, Potassium-40 and Cesium-137) in mussels and shells of Mollusca have been calculated in order to determine the species that could be used as Bioindicators for these isotopes. Statistical analysis of the results using the box plot method showed that the mussels of Spondylus gaederopus spinosus and Chama pacifica can be used as biomonitor for the studied radionuclides in addition to shell of Strombus decorus persicus and Spondylus gaederopus spinosus. While the mussels of Brachidonta variabilis and Spondylus gaederopus spinosus have shown good selectivity for Cd and Pb and Pinctada radiate for Zn and Thais haemostoma for Cu. In addition, the migrant Mullusca from the Red Sea, Strombus decoruspersicus, can be used as biomonitor for lead, Zn and Cu, Cd, while the shell of Thais haemostoma for lead. However, the importance of the results of the present study that are considered as a baseline data for radionuclides in Mullusca distributed along the Syria coast and it is the only study in the eastern Mediterranean basin, that defined the Mollusca species which could be use as biomonitors for radionuclides.

Mediterranean coastal ecosystems suffer many different types of natural and anthropogenic environmental pressure. Microbial communities, major conductors of organic matter decomposition are also subject to these environmental constraints. In this study, our aim was to understand how microbial activities vary at a small spatio-temporal scale in a Mediterranean coastal environment. Microbial activities were monitored in a Pinus halepensis litter collected from two areas, one close to (10 m) and one far from (300 m) the French Mediterranean coast. Litters were transferred from one area to the other using litterbags and studied via different microbial indicators after 2, 5 and 13 months. Microbial Basal Respiration, qCO₂, certain enzyme activities (laccase, cellulase, β-glucosidase and acid phosphatase) and functional diversity via Biolog microplates were assayed in litterbags left in the area of origin as well as in litterbags transferred from one area to the other. Results highlight that microbial activities differ significantly in this short spatial scale over time. The influence of microlocal conditions more intensified for litters situated close to the sea, especially during summer seems to have a stressful effect on microbial communities, leading to less efficient functional activities. However, microbial activities were more strongly influenced by temporal variations linked to seasonality than by location. Copyright © 2014 Elsevier B.V. All rights reserved.

Full Text Available This study aims to analyze the principal factors affecting the interaction of 137Cs, 60Co and 89Sr with coastal sediments and their importance for migration of these ions in surface water. The second goal is to assess the acceptability of radiological consequences of proposed routine discharges of nuclear installations for radioactive materials into surface water as well as to confirm the suitability of the site to select and to establish limits for radioactive discharge into water. Uptake of the investigated ions by Mediterranean Sea bottom sediment samples have been studied as a function of liquid to solid ratio (V/m and contact time using batch technique. The suspended sediment concentration, different discharge rates of radionuclides and the distance between the source point in the sea and the beach were investigated. The obtained results show that Kd of Cs+, Co2+ and Sr2+is 20, 32 and 10 l/g, respectively. The lowest effective dose is for 89Sr, while the highest effective dose is for 137Cs, at the same distances. A mathematical model for the migration of the investigated isotopes in surface water was constructed to predict the concentration of these ions for both different distances and time periods.
