Nowadays, more than a third of agricultural production is lost due to abiotic or biotic stress, such as drought, salinity, pests and diseases. Current predictions indicating an expanding world population until the end of the century, one of humanity's greatest challenges should be how to feeding the world in a sustainable way, as future increases in crop yields should be achieved with fewer input of fertilizers and pesticides. These challenges have raised awareness of the importance of the plant root microbiome to improve agricultural and horticultural practices. \u0000Plant roots are colonized by a surprising number of microorganisms, revealing in most cases an intimate symbiotic relationship which facilitates nutrient uptake and provides the host plant with higher resistance against attackers. In this context, plants can be seen as \"superorganisms\" that depend on their root microbiome for important functions. But the impact of plant domestication on the functional diversity and beneficial activities of this root microbiome is still largely unknown. Recent studies showed taxonomic differences in the root microbiome between wild relatives and modern cultivars, mainly in root architecture and root exudation. This leads to the hypothesis that present-day cultivars might have lost traits to recruit and activate host-specific beneficial root microbiota. \u0000Our research project investigates tomato species and native soils in the Andes to explore the taxonomic and functional diversity of their root microbiomes. Next generation sequencing and ‘omics technologies, combined with classic microbiological techniques are being used to obtain insight in the diversity of root-associated microbial communities of tomatoes. We hypothesize that wild tomatoes grown in their native soils harbour unique and higher frequencies of beneficial root microbiota, compared to modern cultivars.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126770189","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}

Here, we report a study on the response of ZnO nanostructures based H2S sensor at different temperatures. It was observed that the response didn’t exhibit the same behavior at all concentrations with increase in temperature. It can be attributed to adsorbed oxygen molecules, adsorption-desorption rate and number of surface charge carriers, which vary with temperature. This variation in sensor response with temperature for different concentration can be useful in developing single sensor based electronic nose to detect multiple gases selectively.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124376047","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}

A completely randomized design with seven treatments and five repetitions was used. The treatments were the four native isolates (TI6301, TS6304, PS5002, PS5003; at a concentration of 1 x108 conidia.mL-1), Chemical (Engeo at a dose of 1mL.L-1 water), a commercial biological (Micosplag at a dose of 0.5 g.L-1 of water) and a control treatment with sterile distilled water. The treatments were applied by immersion. Mortality assessment was recorded at 5, 10, and 15 days after treatment application. Abbott's formula was used for the correction of mortality. To determine the confirmed mortality, dead adults were conditioned in humid chambers to verify the presence of mycelium on dead insects. The data was processed by ANOVA, the comparison of means was made with the Tukey test (P <0.05). The chemical treatment showed an immediate response in adults of M. hemipterus with a 100% mortality efficiency before the first 24 hours, while the native isolates began to reflect mortalities from the second day. The native isolates of Metarhizium spp. TI6301, TS6304 and PS5002 caused accumulated and corrected mortalities above 70%, and Micosplag treatment reached an efficiency of 4.17%. Confirmed mortalities were between 72.4 and 76% with native isolates TS6304 and TI6301, respectively on adults of M. hemipterus.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114613205","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 not only involves training tasks, but also those aspects that can influence both performance improvement and injury prevention. These aspects are known as invisible training. Invisible training will improve the recovery between sessions, reduce the risk of injury and better assimilate the training. The assumption of these basic measures, together with mental and physical training, will be decisive for sports performance. For example, in endurance sports, training load, nutrient intake and sleep are key factors that modulate immune function, positively or negatively. Regular physical activity as well as a balanced diet and sufficient sleep are associated with improved immune function. On the other hand, prolonged or too intense exercise, energy deficit and lack of sleep decrease the function of the immune system and increase the probability of suffering from infections and pathologies. Therefore, psychological training, rest, nutritional and hydration habits and social aspects will be a necessary activity for the technical managers of a sport, if they wish to achieve medium or long-term physical objectives.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128927789","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 systems either require the visitors to provide details of authenticity, for instance, ID cards, passwords, etc. or require someone to explicitly be near the entrance to manually check the details. There are even some existing security systems which become cumbersome for the owners by seeking permission time and again even when the visitor is a frequent one. This paper, therefore is focused on providing a smart solution, without compromising security, by employing a system which will not only grant access to authorized visitors, but will also allow some expected visitors to walk through the doors and restrict the rest even when there is no one physically present near the entrance or anywhere near the concerned area to manually check on the visitors. This system will therefore solicit permission from the owner only when the visitor is unknown. This remote access system therefore uses face recognition, which is a biometric artificial intelligence based technology, and Internet of Things (IoT) to give access to the known visitors when it recognizes them successfully or to give access to the expected visitors by sending an e-mail to the owner with a picture of the visitor, to let the owner decide whether or not to give access to the visitor even when the owner isn’t anywhere near the entrance. For face recognition, histogram of oriented gradient has been used as it requires lower computational time and lower processing power. To allow the owner to remotely send controlling commands to the raspberry pi, Flask has been used to host a webpage designed solely for the stated purpose, along with serveo that allows remote port forwarding. The system also uses an IoT API (ThingSpeak) to upload the name of the authorized visitors and their time of arrival.","PeriodicalId":337320,"journal":{"name":"Proceedings of MOL2NET 2019, International Conference on Multidisciplinary Sciences, 5th edition","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130843208","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}
