One of the actions that took place as part of the above project was the creation of an in situ botanical garden in order to raise public awareness of the environment and the flora of the region. During the operation of the garden, the visitors answered questions related to their satisfaction or dissatisfaction of their visit. They also made suggestions for the improving of the garden. According to the number of the visitors and the analysis of the questionnaires, the operation of the garden was satisfactory. The in situ botanical garden proved useful not only for environmental awareness and education, but also for local economy. Two years since its creation, the garden eventually stopped operating. The main reason was lucky of funding. Based on the experience gained, it is suggested that the garden should be re-created under a new approach. Regions, such as Zagori, whose economy is based on environmental tourism, would benefit greatly from such structures. Moreover, in situ botanical gardens can play an important role in the protection of Greece＇s rich flora.展开更多

Wood transportation in Greece is carried out, almost exclusively, by trucks. The aim of this study is to analyze the evolution of timber trucking in Greece through the analysis of wood transportation waybills. A total of 1,471 waybills have been collected and analyzed that cover the period 1981-2008 from nine of the most productive and representative forest districts in Greece, in terms of timber production. The final dataset included information on the type and technical characteristics of truck types, the transported wood quantities and haulage distances. Furthermore, data on the wood transportation cost for the year 2010 have been collected and analyzed. According to the results, the number of two-axle trucks that dominated in the 1980s is reducing rapidly, mostly to the benefit of larger three-axle and four-axle trucks. More than three quarters （77%） of wood transportation is conducted in the period June-October. Mean vehicle load per vehicle type differs between conifer and broadleaved species from 7.1% up to 23.9%. Transportation of stacked wood with semitrailers is conducted with overloaded trucks, which could entail serious problems for public safety and the condition of road network. New design standards will enhance serviceability of the wood transportation routes and environmental protection.展开更多

This paper proposes and presents a proactive methodology for port safety risk assessment （including the techno-economically effective prioritized control） which constitutes an adaptation of the FSA （Formal Safety Assessment） for ships. The ability of the proposed methodology to offer this standardized approach for PRA （Port Risk Assessment） is demonstrated through reference to the container terminal of the Greek Port of Thessalonica, for which an empirical study is contacted utilizing the historical record of encountered accidents with regard to their frequency of occurrence and their impact upon the human and environmental resources of the port.展开更多

GIS analysis of topographic data and geological mapping revealed flanks of raised terraces created on Quaternary marine deposits. Luminescence ages of sediments from the three westernmost marine terraces tend to be consistent OIS-5, OIS-7 and OIS-9, respectively, thus agreeing with the three latest warm stages of the Pleistocene. Moreover, the type and the extent of deformation of the dated marine terraces allowed us to reflect on the neotectonic configuration of western Messenia as well as to conclude that progressive differential uplift over the last 300 ka has induced a dome-like structure to the upper crust of western Messenia.展开更多

In this article, a comprehensive literature search was conducted for the prevalence of hepatitis C virus(HCV) infection in Greece, since data on the HCV prevalence, viremia and genotypes are important for developing strategies to manage or eliminate HCV infection. In addition, the pattern of HCV infection was analyzed according to the geographic region and the risk factors. These differences reflect not only distinct epidemiological characteristics among populations, but also differences on the strategy of data acquisition and quantification. Although there are not enough data, the estimation of the current prevalence of Hepatitis C in Greece ranges from 0.5% to 2%. The most important risk factors for HCV infection include blood product transfusion, intravenous drug use, chronic hemodialysis, organ transplantation, occupational exposure, sexual transmission, and vertical transmission. Because of lack of vaccine or effective post-exposure prophylaxis for HCV, the main focus of prevention is to recognize and control these risk factors. HCV infection in Greece is closely associated with the development of chronic liver disease, cirrhosis, and primary hepatocellular carcinoma. As far as the genotype distribution is concerned genotype 1 estimated to be 45%-47% and it constitutes the prevalent genotype in Greece, followed by genotype 3.展开更多

Elections were held, seriatim, one alter another, contrived supposedly to reflect the wishes of ethnic Russians in cities along Ukraine＇s eastern border, results of which triggered declarations by separatists of ＂independence＂ followed by formation of ＂people＇s republics＂ as city states. What this signifies is a clash of cultural expectations： of core values, both in the hearts and minds of all parties involved, and in the methods chosen by Russian Federation and Ukrainian independence movement leaders compared with Western governments. If Russia is revoking its transfer of the Crimea to Ukraine on an assertion that such transfer 60 years back was improvident then the Western Alliance should respond by revoking the Potsdam Declaration and other agreements investing Russia with control of Krnigsberg （renamed Kaliningrad） including the Treaty of Paris, and possibly revoking commitments made improvidently at the Teheran and Yalta summit conferences, transferring what was Eastern Poland west of the Curzon Line to the Soviet Union and eventually to Ukraine. If the West will tolerate a Russian siege of Crimea, it should forthwith impose an Allied siege of Kaliningrad and occupy that oblast immediately, retuming Krnigsberg to sovereignty under Lithuanian or Polish and EU control with annexation as a NATO base. What the West with NATO must do is to fight encirclement with encirclement including military, information, economic, trade encirclement as part of what is termed ＂hybrid warfare＂. Stopping military advancement eastward into Europe is only one prong of the problem. Another is Greece, a country that has formed the foundation of the defense of Europe to its own economic detriment. Ukraine as a hot spot is the consequence of China＇s ambition to partner with Ukraine in construction of a post-Panamax deep water cargo port on the Crimean peninsula, prompting Russian Federation opposition （Chinese Billionaire, 2013）. This paper proposes that China transfer its deep water port to Greece fund it through a new East Europe Infrastructure Investment Bank （EEIIB）, achieve the same USD Trillion annual trade influx into the European Union, relieve Greece＇s agony without austerity by inaugurating a Chinese ＂Marshall Plan＂ to become the ＂Chen Yi Plan＂, relieve Greece＇s economic agony without imposing austerity by relocating China＇s planned deep water post-Panamax mega-port from Yevpatoria in Crimean Peninsula to a suitable Greek port, thereby making Greece sustainably rich much as the Marshall Plan did for post-war Germany.展开更多

Furthermore, the disproportion between woman＇s and man＇s work and the mentality that labour and the raising of child is a burden that only woman has to bear, needs to be eliminated. This burden is softened by the protection provided to pregnant women by the state. This way, a great effort is made to promote the equality in working relations between men and women. This kind of protection is realized through the National Health and Social Care by giving economical provisions and through legislative regulations in order to harmonize work and parental role. In this study, regulations and services along with their health care personnel, referring to motherhood＇s protection in Greece, are presented and related data concerning other EU countries are given. Until now, the existing system of maternity of the ＂Social State＂ has not reached yet the desired goal.展开更多

To be successfully exploited it is important to know the mineralogical and microstructural characteristics of the ore. Besides, the identification of the mineralogical components as well as the fabric description, can lead to the interpretation of the mechanism of deposit genesis. The aim of the present study is the microscopic and microanalytical investigation of the Fe-Ni ores from Komnina Vermion area (N.W. Greece). The mineralogical composition of the ore is mainly hematite, quartz, chromite and chlorite, while in minor quantities goethite, nickeliferous chlorite, serpentine, talc and calcite are also present. The ore structure is allotriomorphic inequigranular and the texture is oolitic-pisolitic. According to microscopic examination the deposit can be registered as a secondary pseudo-autochthonous.展开更多

A general overview of the forests, forest management and forest biodiversity of Greece are briefly summarized. The distribution of the main forest species and their ecosystems in the Geographic regions of Greece is presented in a tabular form. Their multiple functions and uses, their management type/regime, their risks and threats, protection and conservation measures are also synoptically described. Furthermore, adaptive forest management and silviculture as well as management of genetic diversity in order to face climate change are also analysed. Research priority areas on biodiversity and challenges for biodiversity research and related policy in Greece have been summarized. The new Rural Development Program (2014-2020), which is currently in the final phase of implementation, will take into consideration the forest itself and forest-related European and National legal obligations. Finally, major conclusions and research priority areas on future management and conservation of forests are highlighted.展开更多

The Estuarine and Lake CΟmputer Model three-dimensional hydrodynamic model has been used, to simulate numerically the effects of the strong tide conditions, the atmospheric forcing, and the oceanographic conditions. Water age was calculated in all computational cells and its renewal was examined with the “pure” water of the open sea both on the surface layers, where the effect of tide and wind was pronounced, as well as on the deeper layers and bottom. It was investigated if in surface layers the tide and the wind restore the water of the study area, thus preventing its renewal. In the remote area, the mixing and dilution of the pollutants contained in the treated municipal waste of five installed diffusers in this complex hydrodynamic field, generated by the aforementioned loads, is simulated. It was found that even a slight stratification density has the effect of restricting the vertical mixing and entrapment of dirt in the deeper layers. The combined impact of municipal waste effluents on selected areas of high economic, tourist and environmental value in the Euboean Gulf was assessed. It was found out, that the Diffuser 2 has a great effect in all the five selected areas, because it has greater waste water discharge and because of the tide, who produce a velocity field and transfer the pollutants in longer distances. It was also investigated indicatively in an important area, whether the presence of tide contributes to better mixing and dispersing of pollutants and to better water quality or, on the contrary, as it restores remote pollutants that were released earlier.展开更多

In a typical residential building located in Crete, Greece, its annual operating energy has been appraised at 170 KWh/m2 and its embodied energy at 30 KWh/m2. Various locally available renewable energies including solar energy, solid biomass and low enthalpy geothermal energy with heat pumps have been considered for generating the required heat and offsetting the grid electricity used. Their technologies are mature, reliable and cost-effective. Offset of the annual grid electricity use in the building with solar-PV electricity is allowed according to the net metering regulation. For zero carbon emissions due to embodied energy of the building, generation of additional solar electricity injected into the grid is required. A mathematical model has been developed for sizing the required solar-PV system installed in the building in order to offset the grid electricity use. For a residential building in Crete, Greece with a covered area of 100 m2, the power of the additional solar-PV system has been estimated at 1.6 KWp and its cost at 2400 €. In the current work, it is indicated that the creation of a zero CO2 emissions residential building due to life cycle energy use in Crete, Greece does not have major difficulties and it could be achieved relatively easily.展开更多

文摘Hepatitis B has long been a serious public health problem both in Greece and in Albania.In the February 2009 issue of World Journal of Gastroenterology,Resuli et al presented the interesting epidemiological data concerning hepatitis B virus infection in Albania.The results of this study were discussed and several data from our similar research were provided.
文摘Hepatitis C is a global health issue and constitutes a major cause of chronic liver disease worldwide. In this article, a comprehensive literature search was conducted for the prevalence of hepatitis C virus(HCV) infection in Greece, since data on the HCV prevalence, viremia and genotypes are important for developing strategies to manage or eliminate HCV infection. In addition, the pattern of HCV infection was analyzed according to the geographic region and the risk factors. These differences reflect not only distinct epidemiological characteristics among populations, but also differences on the strategy of data acquisition and quantification. Although there are not enough data, the estimation of the current prevalence of Hepatitis C in Greece ranges from 0.5% to 2%. The most important risk factors for HCV infection include blood product transfusion, intravenous drug use, chronic hemodialysis, organ transplantation, occupational exposure, sexual transmission, and vertical transmission. Because of lack of vaccine or effective post-exposure prophylaxis for HCV, the main focus of prevention is to recognize and control these risk factors. HCV infection in Greece is closely associated with the development of chronic liver disease, cirrhosis, and primary hepatocellular carcinoma. As far as the genotype distribution is concerned genotype 1 estimated to be 45%-47% and it constitutes the prevalent genotype in Greece, followed by genotype 3.
文摘In every emergency medical situation,access to emergency medical services is an inalienable right of any citizen.The average acceptable time to provide first aid assistance is 60 minutes.In this paper,the possibility of using helicopters for air travel in mountainous areas was examined for the first time for all of Greece and especially for a mountainous and isolated area such as the Municipality of Agrafa.Initially,the time distance-virtual distance,from the hospitals was calculated at the national level of Greece,with an acceptable first contact time of 60 minutes(golden hour),i.e.,less than two hours from the nearest hospital to the incident and back to the hospital and the relevant conclusions are drawn.Then,the case study of Municipality of Agrafa,one of the most mountainous areas in Greece,was examined.The time distance of the settlements from the nearest primary health point,namely the Primary Health Centre(PHC)of West Fragkista,was calculated and the transportation by ground means was compared with the corresponding time by flying means,to investigate the contribution of air transportation or not,of the timely arrival of the patients in the appropriate health structure.Finally,possible helicopter landing locations were identified,using a geographic information system to facilitate the process of air medical transportation in the Municipality of Agrafa.
文摘The Russian Federation unilaterally invaded the Republic of Ukraine＇s Crimean Peninsula, then commenced to occupy more of Eastern Ukraine on the transparent pretext of protecting Russian speakers in 2014, using masked ＂zombie＂ fighters but denied that they were uniformed Russian soldiers, violating several agreements from 1954 to 1994 and legitimate international expectations before and afterwards. Elections were held, seriatim, one alter another, contrived supposedly to reflect the wishes of ethnic Russians in cities along Ukraine＇s eastern border, results of which triggered declarations by separatists of ＂independence＂ followed by formation of ＂people＇s republics＂ as city states. What this signifies is a clash of cultural expectations： of core values, both in the hearts and minds of all parties involved, and in the methods chosen by Russian Federation and Ukrainian independence movement leaders compared with Western governments. If Russia is revoking its transfer of the Crimea to Ukraine on an assertion that such transfer 60 years back was improvident then the Western Alliance should respond by revoking the Potsdam Declaration and other agreements investing Russia with control of Krnigsberg （renamed Kaliningrad） including the Treaty of Paris, and possibly revoking commitments made improvidently at the Teheran and Yalta summit conferences, transferring what was Eastern Poland west of the Curzon Line to the Soviet Union and eventually to Ukraine. If the West will tolerate a Russian siege of Crimea, it should forthwith impose an Allied siege of Kaliningrad and occupy that oblast immediately, retuming Krnigsberg to sovereignty under Lithuanian or Polish and EU control with annexation as a NATO base. What the West with NATO must do is to fight encirclement with encirclement including military, information, economic, trade encirclement as part of what is termed ＂hybrid warfare＂. Stopping military advancement eastward into Europe is only one prong of the problem. Another is Greece, a country that has formed the foundation of the defense of Europe to its own economic detriment. Ukraine as a hot spot is the consequence of China＇s ambition to partner with Ukraine in construction of a post-Panamax deep water cargo port on the Crimean peninsula, prompting Russian Federation opposition （Chinese Billionaire, 2013）. This paper proposes that China transfer its deep water port to Greece fund it through a new East Europe Infrastructure Investment Bank （EEIIB）, achieve the same USD Trillion annual trade influx into the European Union, relieve Greece＇s agony without austerity by inaugurating a Chinese ＂Marshall Plan＂ to become the ＂Chen Yi Plan＂, relieve Greece＇s economic agony without imposing austerity by relocating China＇s planned deep water post-Panamax mega-port from Yevpatoria in Crimean Peninsula to a suitable Greek port, thereby making Greece sustainably rich much as the Marshall Plan did for post-war Germany.
文摘Pregnancy and motherhood are two situations which impose on the special regulation of the working conditions in order to secure the protection of the physical and psychological health of woman. Furthermore, the disproportion between woman＇s and man＇s work and the mentality that labour and the raising of child is a burden that only woman has to bear, needs to be eliminated. This burden is softened by the protection provided to pregnant women by the state. This way, a great effort is made to promote the equality in working relations between men and women. This kind of protection is realized through the National Health and Social Care by giving economical provisions and through legislative regulations in order to harmonize work and parental role. In this study, regulations and services along with their health care personnel, referring to motherhood＇s protection in Greece, are presented and related data concerning other EU countries are given. Until now, the existing system of maternity of the ＂Social State＂ has not reached yet the desired goal.
文摘Nickel laterites are considerable sources of nickel. To be successfully exploited it is important to know the mineralogical and microstructural characteristics of the ore. Besides, the identification of the mineralogical components as well as the fabric description, can lead to the interpretation of the mechanism of deposit genesis. The aim of the present study is the microscopic and microanalytical investigation of the Fe-Ni ores from Komnina Vermion area (N.W. Greece). The mineralogical composition of the ore is mainly hematite, quartz, chromite and chlorite, while in minor quantities goethite, nickeliferous chlorite, serpentine, talc and calcite are also present. The ore structure is allotriomorphic inequigranular and the texture is oolitic-pisolitic. According to microscopic examination the deposit can be registered as a secondary pseudo-autochthonous.
文摘This is a review paper based on national and international literature, national inventories and empirical approach. A general overview of the forests, forest management and forest biodiversity of Greece are briefly summarized. The distribution of the main forest species and their ecosystems in the Geographic regions of Greece is presented in a tabular form. Their multiple functions and uses, their management type/regime, their risks and threats, protection and conservation measures are also synoptically described. Furthermore, adaptive forest management and silviculture as well as management of genetic diversity in order to face climate change are also analysed. Research priority areas on biodiversity and challenges for biodiversity research and related policy in Greece have been summarized. The new Rural Development Program (2014-2020), which is currently in the final phase of implementation, will take into consideration the forest itself and forest-related European and National legal obligations. Finally, major conclusions and research priority areas on future management and conservation of forests are highlighted.
文摘The mixing characteristics in the marine environment of the Euboean Gulf are studied. The Estuarine and Lake CΟmputer Model three-dimensional hydrodynamic model has been used, to simulate numerically the effects of the strong tide conditions, the atmospheric forcing, and the oceanographic conditions. Water age was calculated in all computational cells and its renewal was examined with the “pure” water of the open sea both on the surface layers, where the effect of tide and wind was pronounced, as well as on the deeper layers and bottom. It was investigated if in surface layers the tide and the wind restore the water of the study area, thus preventing its renewal. In the remote area, the mixing and dilution of the pollutants contained in the treated municipal waste of five installed diffusers in this complex hydrodynamic field, generated by the aforementioned loads, is simulated. It was found that even a slight stratification density has the effect of restricting the vertical mixing and entrapment of dirt in the deeper layers. The combined impact of municipal waste effluents on selected areas of high economic, tourist and environmental value in the Euboean Gulf was assessed. It was found out, that the Diffuser 2 has a great effect in all the five selected areas, because it has greater waste water discharge and because of the tide, who produce a velocity field and transfer the pollutants in longer distances. It was also investigated indicatively in an important area, whether the presence of tide contributes to better mixing and dispersing of pollutants and to better water quality or, on the contrary, as it restores remote pollutants that were released earlier.
文摘The possibility of creating zero CO2 emissions residential buildings due to life cycle energy use in the island of Crete, Greece has been examined. In a typical residential building located in Crete, Greece, its annual operating energy has been appraised at 170 KWh/m2 and its embodied energy at 30 KWh/m2. Various locally available renewable energies including solar energy, solid biomass and low enthalpy geothermal energy with heat pumps have been considered for generating the required heat and offsetting the grid electricity used. Their technologies are mature, reliable and cost-effective. Offset of the annual grid electricity use in the building with solar-PV electricity is allowed according to the net metering regulation. For zero carbon emissions due to embodied energy of the building, generation of additional solar electricity injected into the grid is required. A mathematical model has been developed for sizing the required solar-PV system installed in the building in order to offset the grid electricity use. For a residential building in Crete, Greece with a covered area of 100 m2, the power of the additional solar-PV system has been estimated at 1.6 KWp and its cost at 2400 €. In the current work, it is indicated that the creation of a zero CO2 emissions residential building due to life cycle energy use in Crete, Greece does not have major difficulties and it could be achieved relatively easily.
文摘Patients with end-stage renal disease in Greece are facing long waiting times to receive a kidney transplant from a deceased donor.Living kidney donation offers a valuable alternative that provides optimal outcomes and significantly expands the donor pool but still remains relatively underutilised.Developments around the world in the field of kidney transplantation mandate a change in current practice to include additional options for living donation through paired exchange,antibody-incompatible transplantation and other strategies,following careful consideration of the cultural and ethical factors involved in these complex clinical decisions.An increase in living donation rates may be achieved in several ways,including targeted campaigning to overcome potential barriers.Educating clinicians on transplantation will prove as equally important as informing patients and prospective donors but requires training and resources.Adoption of established practices and implementation of new strategies must be tailored to the needs of the Greek donor and recipient population.Local beliefs about donation,perception of associated risk and other social characteristics must be considered in the design of future strategies.Facilitating living donation in a safe environment with appropriate donor and recipient education will form the solid foundation of a new era of kidney transplantation in Greece.
基金funded by the Hellenic and Chinese Governments,in the frame of the Greek-Chinese R&T Cooperation Programme project“Comparative study of extreme climate indices in China and Europe/Greece,based on homogenised daily observations—CLIMEX”(Contract T7ΔKI-00046)the National Key Technologies Research and Development Program“Comparative study of changing climate extremes between China and Europe/Greece based on homogenised daily observations”(Grant No.2017YFE0133600)。
文摘In this paper,we describe and analyze two datasets entitled“Homogenised monthly and daily temperature and precipitation time series in China during 1960–2021”and“Homogenised monthly and daily temperature and precipitation time series in Greece during 1960–2010”.These datasets provide the homogenised monthly and daily mean(TG),minimum(TN),and maximum(TX)temperature and precipitation(RR)records since 1960 at 366 stations in China and 56stations in Greece.The datasets are available at the Science Data Bank repository and can be downloaded from https://doi.org/10.57760/sciencedb.01731 and https://doi.org/10.57760/sciencedb.01720.For China,the regional mean annual TG,TX,TN,and RR series during 1960–2021 showed significant warming or increasing trends of 0.27℃(10 yr)^(-1),0.22℃(10 yr)^(-1),0.35℃(10 yr)^(-1),and 6.81 mm(10 yr)-1,respectively.Most of the seasonal series revealed trends significant at the 0.05level,except for the spring,summer,and autumn RR series.For Greece,there were increasing trends of 0.09℃(10 yr)-1,0.08℃(10 yr)^(-1),and 0.11℃(10 yr)^(-1)for the annual TG,TX,and TN series,respectively,while a decreasing trend of–23.35 mm(10 yr)^(-1)was present for RR.The seasonal trends showed a significant warming rate for summer,but no significant changes were noted for spring(except for TN),autumn,and winter.For RR,only the winter time series displayed a statistically significant and robust trend[–15.82 mm(10 yr)^(-1)].The final homogenised temperature and precipitation time series for both China and Greece provide a better representation of the large-scale pattern of climate change over the past decades and provide a quality information source for climatological analyses.
