Carassius auratus were exposed to 50µg/l of ASDI mixture for 12 weeks. Recorded mid-term assays shows, significant increased levels of cortisol and aromatase after 4-weeks. Reduction in aromatase activity at 8 and 12 weeks is followed by estradiol (E2) showing a positive correlation between them. Hence, 11-Keto reduced significantly at 4-8 weeks and enhanced at 12 weeks. Remarkable reduction in E2 and 11-Keto may be correlated with the reduced egg production in stressed fish by these herbicides. However, no remarkable change in testosterone is observed at 4 and 12 weeks as compared to the control. ASDI mixture treatment induced remarkable induction in vitellogenin (Vtg) biomarker protein in male stressed fish. Furthermore, it may confer that modulation in the pathway of the reproductive cycle may alter the gamete quality, quantity and consequently may disrupt spawning and mating behaviour in fishes even at a realistic level of pollutant in the environment.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116423901","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 so called AGW (Anthropogenic Global Warming), is based on thousands of climate simulations that indicate that human activity is virtually solely responsible for the recent global warming. The climate models used are derived from the meteorological models used for short-term predictions. They are based on the fundamental and empirical physical laws that govern the myriad of atmospheric and oceanic cells integrated by the finite element technique. Numerical approximations, empiricism and the inherent chaos in fluid circulations make these models questionable for validating the anthropogenic principle, given the accuracy required (better than one per thousand) in determining the Earth energy balance. Aims and methods. The purpose is to quantify and simulate behavioral models of weak complexity, without referring to predefined parameters of the underlying physical laws, but relying exclusively on generally accepted historical and paleoclimate series. Results. These models perform global temperature simulations that are consistent with those from the more complex physical models. However, the repartition of contributions in the present warming depends strongly on the retained temperature reconstructions, in particular the magnitudes of the Medieval Warm Period and the Little Ice Age. It also depends on the level of the solar activity series. It results from these observations and climate reconstructions that the anthropogenic principle only holds for climate profiles assuming almost no PCA neither significant variations in solar activity. Otherwise, it reduces to a weak principle where global warming is not only the result of human activity, but is largely due to solar activity.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122092604","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}

An attempt has been made to demonstrate, through a few examples, that the construction of a sensitivity towards a tourism attentive to geological and geomorphological values, important because it leads to greater attention to the sites, their conservation and protection and ultimately to respect for the environment, requires, for their effective valorization, scientific knowledge, albeit at different levels of depth, of what is observed, of what is protected, and above all of what natural phenomena are the result. It is easy to appreciate, observe, photograph, and keep the memory of a beautiful mountain, a landscape, or a particularly original geological or geomorphological aspect, often identifiable with a geosite. It is less easy to recognize that the same value for the purposes of geoconservation, and therefore of valorization, can be attributed to phenomena, perhaps less beautiful from an aesthetic and environmental point of view, with a lower visual impact, significant both from a geological point of view, but even more historical, cultural, anthropic, revealing unexpected connections and transversal cultural and intangible values between different cultural areas. These sites, places, contexts can have a profound impact on human sensitivity and perception, transforming a geological place into a place of cultures, a geo-site into a geoheritage-site. This research has tried to deepen this aspect, proposing some cases, situated in an author’s known context, and particularly appreciated by the author, precisely because of the wealth of stimuli they can provide to the interested tourist, but also to the student to whom we wish to convey the perception of richness and depth of an environmental context, rich in scientific contents but also in cultural values.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122951356","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 present research aimed to observe the vegetation health index across the semi-arid regions of Karnataka state in 2015-2019 using GIS and remote sensing techniques. Landsat-8 dataset images, with a 30 m spatial resolution and from various platforms were used to recognize the Vegetation Condition Index and Temperature Condition Index. The VCI is dependent on the NDVI datasets. The Temperature Condition Index used LST. As an outcome, the VHI was generated and classified into 5 categories of drought: no drought, mild, moderate, severe, and extreme drought. The results indicate that the highest % of the extreme agricultural drought found in Chinthamani taluk is about 740.20 squares Km (20%) area. In the S-W monsoon showed Bagepalli is about 397.70 squares Km (18%), and Sidhlaghatta taluk is about 26 % (338.55 squares Km). In the North-east Monsoon extreme drought severity was affected in Malur at 22% (704.05 squares Km), Mulubhagilu at 26 % (909.99 squares Km), and Bangarapete at 21% (879.64 sq. km) of the area have severely affected the agriculture and vegetation from 2015-2019 respectively. Severe to moderate drought occurred in the north–east part of both areas of Kolar and Chikkaballapura districts. 2016 and 2017 experienced a less level of drought % with compared to the other study years. This study allows the monitoring of decision-makers, resolves drought conditions, and investigates more beneficially.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"59 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131624378","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}

Average annual rainfall is usually regarded as the most important factor controlling soil moisture regime, water availability, and therefore various environmental variables. The present study deals with the ecology of an area located in the semi-arid area of Israel, where average annual rainfall is ~280 mm. The area is located in a loess covered area. The loess cover was deposited during a wet climatic phase. However, pedological and ecological data point to a desertification effect. Data obtained show that non-climatic factors, such as local surface properties, can exert a strong influence on the environment. In addition, the global models disregard the characteristics of the local rainfall regime, such as the distribution of rain intensities, and the duration of individual rain-showers during a rainstorm. Under the present rainfall regime about 85% of the rains are below 5 mm/hr,1, rainfall is also highly intermittent, limiting runoff generation, and infiltration depth. Under such conditions, a high evaporation rate leads to a soil salinization process.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125166842","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}

Corbetti geothermal prospect is located at about 250 km south of Addis Ababa and 20km from Awassa city and the area is bounded by Lake Awassa to the south and Lake Shalla to the north with geographic location between latitude 7.170N-7.250N and longitudes 38.300E-38.470E. The Corbetti Caldera is characterized by Quaternary volcano-tectonic activity which is mainly silicic volcanism and a resurgent caldera structural system. Quaternary volcanism is associated with a wide spread of steaming ground and fumarolic activity which could confirm the existence of a heat source at depth. Fifty six (56) VES points, 200 gravity and about 200 magnetic data have been used and analyzed. The results are presented as magnetic, gravity and electrical counter maps for qualitative interpretation. Constrained gravity and magnetic 2D model and results obtained from the geoelectric section were made for quantitative interpretation. The complete Bouguer gravity anomaly in conjugation with the total magnetic field anomaly map of the area indicates the existence of intrusion beneath the caldera, i.e. the highest Bouguer gravity anomaly resulting from the higher density of the intrusion. Correspondingly the shallower heat source caused by this intrusion is characterized by the lowest magnetic anomaly response. Results from vertical electrical soundings along profile-2 indicate the presence of a middle thicker conductive zone which is associated with the increase in temperature and alteration of rocks. Apparent resistivity map for AB/2=1810m and AB/2=2700m shows low resistivity anomaly follows the eastern and northern caldera rim, stretching north of the caldera towards Lake Shalla.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"19 34","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132747757","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}

For a model of equal-rotation velocity of matter, where the main component of plasma is rotating around a common axis with the same velocity close to the light velocity, with a high Lorentz factor (gamma rate), it is concluded that the matter distribution is condensed to a region with a much smaller radius than that of the event horizon of the Kerr spacetime. The gravitational waves that are generated from the condensed matter region due to the orbital motion of the binary, return towards the source, after ceasing at the critical sphere in the vacuum region of spinning Kerr spacetime. At the stage where returning waves encounter with foreword waves, the gravitational waves are deformed to standing waves that carry no energy outside of the event horizon. We conclude that no gravitational wave is radiated from the supermassive black hole binary.","PeriodicalId":298809,"journal":{"name":"Earth & Environmental Science Research & Reviews","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127286241","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}
