It consists dominantly of granite and lesser granodiorite and quartzolite. Petrographic and geochemical data revealed three granite groups: the biotite-hornblende granite (quartzolite - BHG); the biotite granite (BG) and the biotite-muscovite granite (BMG). The rocks generally have calc-alkaline and high-K calc-alkaline affinities, and calc-alkalic to alkali-calcic, peraluminous and ferroan and magnesian geochemistry. They are characterized by LILE enrichment, high LREE fractionation factor [(La/Yb) (6.74 to 45.14] with weak to moderate negative Eu (Eu/Eu* = 0.38 to 0.62) and strong negative Nb, P and Ti anomalies. Variation in the behavior of lithophile elements (Ba, Sr and Rb) revealed diverse granite trend such as “high and low Ba-Sr”; “normal”, “anomalous” “strongly differentiated” and “granodiorite and quartz diorite” granite. Their display of similar trace elements and REE patterns suggest they are cogenetic. Major and trace element data indicate differentiation of a mafic magma and partial melting of crustal components inherited from shale-greywacke and quartzose sedimentary protoliths in volcanic arc and post collisional settings. The field and geochemical characteristics of this granite suggest that they are similar to other granites in schist belts in other parts of Nigeria, forming the lateral continuation of the same Pan-African magmatic belt.","PeriodicalId":306249,"journal":{"name":"Challenging Issues on Environment and Earth Science Vol. 7","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127753950","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}

In addition, the Nevado de Toluca Station (15062) for 1964-1985 (initial period; 21 years of records) and 1986-2008 (posterior period; 22 years of records) also show these climatic changes. The box plots for precipitation, evaporation, observed temperature, minimum and maximum of the air, Student's “t” test, regression analysis and linear correlation indicated significant changes in time at p (le) 0.05 for both lakes. Likewise, the Student’s “t” test, regressions and correlations in the water quality records from 2006 to 2011 for Patzcuaro Lake, indicated significant changes in some physicochemical variables, due to agricultural, livestock, forestry, fishing, tourism, trade and cyanobacterial blooms. In El Sol Lake the physicochemical changes over time were related to tourism, livestock activity and phytoplankton biomass; changes associated with anthropic and climatic influence in both lakes throught changes in the meteorological variables. For Patzcuaro and El Sol lakes a decrease in maximum depth, surface area, length and width were associated with an increase in turbidity, nutrients and an increase in phytoplankton biomass and climate change between the initial and posterior periods, due to the change in the heat balance of water through variation in air temperature, precipitation, runoff, and evaporation. A management plan (reforestation, construction of wetlands, water lily harvest, regulation of agricultural activities, domestic, urban, tourist and industrial waste), it is recommended as appropriate for each lake ecosystem.","PeriodicalId":306249,"journal":{"name":"Challenging Issues on Environment and Earth Science Vol. 7","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121354184","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 objective of the current study is to investigate the application of these technologies using either fossil fuels or renewable energies in the hotel industry stating their characteristics, advantages and drawbacks. Various distributed electricity generation technologies, including co-generation of heat and power systems, are examined. Some of them are using renewable energies like solar energy, wind energy and biomass for electricity generation. Others are related with various co-generation systems including fuel cells. Many hotels require almost equal amounts of heat and electricity in their daily operations. Co-generation technologies have the advantage that they can cover almost all of their requirements in both electricity and heat. Some distributed electricity generation technologies including solar photovoltaic energy, co-generation systems, wind turbines and fuel cells are already used in hotels. Their energy efficiency varies in the range of 10% to 90%. Technologies using renewable energies generate carbon-free electricity while others fueled by natural gas generate electricity with low carbon emissions. Each technology has advantages and drawbacks while the possibility of using each technology depends on hotel’s characteristics as well as on the local availability of renewable energy resources. The results of the present study are important in hotel industry since they indicate the possibility of using the environmentally friendly distributed electricity generation technologies for covering their electricity as well as, in some cases, their heating requirements reducing their carbon footprint due to energy use and increasing their energy and environmental sustainability.","PeriodicalId":306249,"journal":{"name":"Challenging Issues on Environment and Earth Science Vol. 7","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126726696","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}

Aviation contributes to the quality of life – allowing us to visit friends and relatives, to travel, to experience new places, to shrink the world. Moreover, the aviation industry provides 56 million direct, indirect, and induced jobs worldwide. On the other hand, aviation affects the environment in many ways: people living near airports are exposed to aircraft noise; aircraft engines emit greenhouse gases and other pollutants to the atmosphere; large amounts of energy and water are consumed for the passenger needs and great volumes of waste are produced; streams, rivers, and wetlands may be exposed to pollutants discharged in storm water runoff from airports and many species of plants and animals are expatriated from the vicinity of airports. These negative externalities have been acknowledged during the last decades and the aviation industry is taking mitigation measures at a growing pace. National and international authorities, aviation institutions, aircraft manufacturers, airlines and airports issue advisory documents and manuals, establish environmental standards, apply new technologies and adopt environmental management systems to achieve environmentally-friendly operations in multiple dimensions: noise, air and water quality; energy consumption, waste production and biodiversity preservation. This chapter offers a comprehensive overview of the adverse environmental impact connected with air transportation and the corrective measures adopted by the aviation industry to mitigate this impact.","PeriodicalId":306249,"journal":{"name":"Challenging Issues on Environment and Earth Science Vol. 7","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114430795","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}

Changes in weather patterns and anthropogenic activities are evident in Uganda and are posing a serious threat to the country’s natural resources, biodiversity and health, as well as the social and economic development. Changes have been predicted to continue in the form of higher temperatures and inter-annual rainfall variability. Emergence and re-emergence of pests and diseases, and increasing frequency of severe floods will continue presenting social and economic hardships. Loss of plant mass due to reduced rainfall and high temperatures, promoting desertification will disturb the symbiotic relationship between plants and animals including insects. Some species of plants and animals may suffer extinction or change in locations and/or behaviour. Controlled anthropogenic activities, enforcement of existing policies and regulations on sustainable use of ecosystem resources, awareness raising to all stakeholders, strengthening institutional capacity to design and implement adaptation and mitigation strategies and improved monitoring of weather patterns and biodiversity are recommended.","PeriodicalId":306249,"journal":{"name":"Challenging Issues on Environment and Earth Science Vol. 7","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114834702","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}
