The location of the River Capture or River Piracy and the sites of the rivers basins, which were separated into two parts, were identified. Also geological features with linear direction, forms of formation of plateaus, intersection, ground landing, and flood sediment and river bifurcation were identified. The geology of the region was also used to detect the occurrence of recent Morphotectonic activities. In this study we find that the upstream of Wadi Abu Ghar basin, was captured by the Sadir and Abu Ghuwair basins. The Sadir and Abu Ghuwair basins were not present at the beginning of the Quaternary period, and these basins were created when a fault occurred with northeast-southwest trend. Most recent studies indicate that the main river streams of the lower valleys were formed during the early Quaternary period. All geological and geomorphological evidences confirm that Recent Neotectonic movements were happened in this part during the Quaternary period.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000407","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46601247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Istanbul has experienced a highspeed urban growth in the last century. While the population of the city was under one million in 1900, it reached to 14 million in 2015. Almost 14 times growth in one century has made Istanbul the largest city in Turkey. High-speed urbanization and transformation of the natural environment and forests into built-up area has a critical impact on the metropolitan’s climate. Due to the alteration of heat energy balance and as a megacity, Istanbul has been affected by increasing severe heat waves in summer. This study focuses on two of the effective urban design factors upon the urban heat islands (UHIs) in Istanbul such as vegetation cover and characteristic of surface materials. The spatial pattern of land surface temperature (LST), surface albedo, the normalized difference vegetation index (NDVI) and land cover-land use (LCLU) are analyzed to explore the cooling or heating impacts of the green areas and the build-up areas on the UHI. The methodology is based on using Landsat 8 OLI (Operational Land Imager) satellite image that captured on 6 September 2015, and available meteorological data include two stations, one in city center (Kandilli Station) and the other one in rural area (Sile Station) that revealed average annual temperature differences 8.3°C in the last decade. The results of the analysis show that artificial surfaces with low albedo and low vegetation cover have the most positive exponential relationship with land surface temperature (LST) and increasing effect on UHI formation. The results of the analysis highlight that high albedo material (HAM), greenery on the surface and on the roofs (VEG), and a combination of them can be used as the UHI mitigation strategies.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":"8 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2017-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000423","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46463204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These components can be attained through the consumption of food, which can be attained from a variety of plants and animals. This attainment of food is thoroughly digested by your body in order to sustain it and provide it with energy for work. Garrett Hardin is an ecologist and philosopher, who warned us about the dangers of overpopulation through his literary work called The Tragedy of the Commons. He specifically outlined the difference in the energy needed for mere maintenance and work capacity for human beings. In this literary work he stated, “for man, maintenance of life requires about 1600 kilocalories a day (‘maintenance calories’). Anything that he does over and above merely staying alive will be defined as work, and is supported by ‘work calories’ which he takes in. Work calories are used not only for what we call work in common speech; they are also required for all forms of enjoyment” (Hardin). Through the Neolithic Revolution, “we abandoned the commons in food gathering, enclosing farm land and restricting pastures and hunting and fishing areas”, around 9000BC in the Fertile Crescent (Hardin). The Neolithic Revolution started the cultivation of “founder crops”, which consisted of wheat, barley, peas, lentils, chickpeas, and flax. The nomadic hunter-gatherers from 8000 BCE commenced the domestication of animals such as dogs, goats, sheep, cattle and pigs (Brown University). Industrial Revolution led to an explosion in improvement of technology and methods for farming, which provided people with the capability to produce massive amounts of food. Throughout the history of human beings, we as a species have never produced more food, than ever with so little manpower.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":" ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000427","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45777592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recognition of this interval is based on lithological changes and an accurate stratigraphic proxy allows to distinguish of three main facies. The use of multivariate (cluster analysis and principal component analysis) and univariate (one-way Anova test) analysis confirm dissimilarities in composition between facies as testified by the significant differences. Sedimentological, geochemical and mineralogical analysis leads to assess paleo-environmental changes and to ascertain the variation of the lysocline and CCD across the glauconitic marker bed. Facies 1, particularly, rich in cobalt, sulfides and iron oxides reflects containment conditions affecting the surface and bottom water. These conditions lead to the extinction of the majority of benthic foraminifera and the disruption in planktonic foraminifers’ assemblage. In addition, the Facies 1 displays a brief shoaling of lysocline and CCD evidenced by the low calcite content, the bad preserved benthic foraminifera associated to the maximum fragmentation shells of planktonic foraminifera. In contrary, the rapid pattern of microfossil and the calcite recovery through the Facies 2 indicate suboxic to oxic conditions and a deepen lysocline and CCD. The cobalt lightly increases within the upper Facies, suggesting slightly oxygen deficient bottom water environment. The base of the glauconitic marker bed seems to be a lateral equivalent of the Latest Danian Event recorded throughout the Tethyan Realm (Spain and Egypt) and the Pacific Ocean.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":" ","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2017-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000428","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45708701","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vehicular traffic is now recognized as one of the main sources of air pollution in Sanctuary and has noticeable impact on air quality. Emissions have been estimated using emission factor and activity based approach recommended by IPCC. The highest concentration of pollutants by different vehicles was recorded in summer (June) which can be attributed to the high vehicular load due to the tourist rush whereas the lowest was recorded in early winter (November). The present observation revealed that the highest emission of criteria pollutants (CO2, CO, NO, SO2, and PM) was emitted by four-wheeler direct injection diesel vehicles (DI) excepting one i.e. carbon monoxide (CO) emitted by four-wheeler gasoline vehicles (4WG). The high emission of pollutants in the summer season (June, July, August) might cause more negative effect to the plants and trees especially to the road side vegetation as compared to early winter season (September, October, November). The number of vehicles was recorded highest in the month of June and lowest was recorded in the month of November. Visiting of the vehicles to the site must be allowed in certain limit in order to keep the fragility of the sanctuary into consideration. The traffic authorities should check the PUC certificate of vehicles before entering the state.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":" ","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000421","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47115185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mücke","doi":"10.4172/2157-7617.1000419","DOIUrl":"https://doi.org/10.4172/2157-7617.1000419","url":null,"abstract":"Investigations of the two minerals concern their chemical compositions and formulae, their intergrowths with other minerals, typical minerals that occur in association with them, their mode of formation within defined types of ore deposits/occurrences and finally also their optical characteristics under reflected light. Mackinawite was observed at 16 localities distributed all over the world from which more than 50 polished sections were available and more than 70 analyses were carried out. Valleriite was found at six localities. Microscopic work was based on more than 40 polished sections and more than 30 analyses. \u0000In the literature, mackinawite is reported as a metal excess phase with the formula (Fe, Ni)1+xS and (x ≤ 0.07). Deduced from analyses of this study, mackinawite has a wider compositional range and the formula: (Fe, Ni, Co)1- xS to (Fe, Ni, Co)1+y S, where x=0.00–0.10 and y=0.00–0.10. Therefore, mackinawite may not only occur as a metal excess phase, but also as a metal deficiency one. The high-temperature (max. about 500°C) mineral mackinawite occurs in various types of sulphidic deposits, and is characteristically accompanied with chalcopyrite, pyrrhotite, sometimes pentlandite, pyrite, sphalerite and cubanite and occurs often in oriented intergrowth within chalcopyrite which is always twinned due to inversion. At lower temperature, mackinawite was also formed by the replacement of chalcopyrite (not twinned) and rarely by that of pentlandite and linneite. \u0000The formula of valleriite is (Fe, Cu)2S2 • 1.5 [(Mg, Al)1(OH)2]. The analyses of this study show, that valleriite has a wider compositional range and the proposed formula is: (Fe, Cu)2S2 • [(Mg, Fe)1(OH)2] • y [Al(OH)0] with x=1.20 – 2.10 and y=0 – 0.50. Identical with the latter formula, namely that Al and vacancies are constituents of the OH-layer, the formula inverts to: (Fe, Cu)2S2 • [(Mg2+, Fe2+, Al3+ y, ϒy/2)1(OH)2] where x=1.24–2.25 and y=0.00–0.26. \u0000Valleriite, formed under mesothermal up to low katathermal conditions, is always a newly-formed mineral. It occurs together with chromite and/or magnetite, mostly along their cracks and fissures, in ultramafic rocks that are serpentinized, but only in the presence of chalcopyrite. Valleriite was also observed as replacer of chalcopyrite. Valleriite decomposes under high-grade metamorphic conditions (e. g. in Outokumpu, Finland).","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":"13 1","pages":"1-14"},"PeriodicalIF":0.0,"publicationDate":"2017-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70382783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently indiscriminate hill cutting is considered as one of the major environmental destructions in Chittagong city. Hill cutting problems are triggering deforestation and loss of biodiversity, local level climate change, increasing water logging and landslides. Remarkably, few researches are available to help identifying geographical distribution of hill cutting areas in Chittagong city, Bangladesh. This paper addresses this gap by conducting field investigations, observations and surveys in Chittagong city Corporation (CCC), Bangladesh. Through field investigations, observations and surveys, this research divides hilly areas in four categories. These include a) existing hilly areas, b) moderately susceptible hilly areas, c) highly susceptible hilly areas, and d) extinct hilly areas. The research suggests that there are still 40 hills in CCC which still are not affected by any hill cutting problems. The moderately susceptible hilly areas are located in Khulsi and Bayazid Bostami thanas. The highly susceptible hilly areas are located in Bayazid Bostami (11 Hills), Khulshi (10 Hills) and Kotowali thanas. The extinct hilly areas are mainly located in Panchlaish, Bayazid, Kotowali and Khulshi thanas. In order to stop hill cutting in Chittagong city, this research suggests six key areas of actions: (i) education and training, (ii) information collection and dissemination, (iii) formation of strong advisory committee, (iv) enforcement of laws by consisting of personnel from Bangladesh Army, Police, Ansar and BDP, (v) monitoring hilly areas by LiDAR DEM and (vi) formation of a monitoring committee to report strength and weakness of hill protection activities time to time.","PeriodicalId":73713,"journal":{"name":"Journal of earth science & climatic change","volume":" ","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2017-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4172/2157-7617.1000420","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49045092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
