Existing vibration technologies imply the high-temperature drying of food grains with further utilization of spent heat carrier for reheating it. In this case, the high-temperature drying of cereals and seed crops (grains, onions, etc.) does not make it possible to maintain high germination, emphasizing the need for low-temperature treatment, which, in this case, reduces the efficiency of spent heat carrier. Therefore, to improve the efficiency of the drying process and technology, it has been proposed to employ vibration low-frequency technologies that ensure seed quality. The trajectory and the kinetic energy of the drum container with a combined mechanical vibration exciter have been calculated for the improved vibratory drum grain dryer. The rational vibration intensity for seed drying providing the following kinetic characteristics has been established: vibration speed, to 0.03 m/s; vibration acceleration, 30 m/s 2 ; vibration intensity, 2.6 m 2 /s 2 ; at amplitude vibration not exceeding 2 mm. It has been also established that the intense warming of a barley layer occurs at a temperature of 50 °C and a humidity of 13.5 %, the final temperature is 42.4 °C, and, at 40 °C, is, accordingly, 35.4 °C. This has confirmed that the low-temperature drying of barley seeds of the variety \"Stalker\" (Ukraine) takes place during the periods of constant and falling drying speed characterized by a high level of germination (95...93 %)","PeriodicalId":268570,"journal":{"name":"SRPN: Other Sustainable Technology (Topic)","volume":"571 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122731916","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 India, 50 % of the remaining task at hand depends upon agribusiness. The responsibility of the agriculture part in the Indian economy is higher than some other divisions in India. In any case, Farmers utilized customary strategy for developing harvests, which involve less profitability of yields. Additionally, an erosion and disintegration are likewise a principle motivation to less profitability of yields. This will impact in diminishes fruitfulness level. Loss of soil supplements through different courses is likewise motivation to diminish soil richness level. Supplements like potassium (K), nitrogen (N), and phosphorus (P) are basic for the evolution of a plant. The advancement in agriculture is vital to tackle these issues in the agribusiness part and shrewd cultivating is that the appropriate response. This can be conceivable utilizing IOT gadgets. Farmers can get the necessary data just as the screen is yield. IOT associates the whole world with the help of sensors and other installed gadgets. The diverse soil tests will be taken from various fields and soil esteems will be determined to utilize a PH sensor where supplements worth will be separated from it. The live information will be sent to the cloud database where information will be put away. Where information will be broke down to improve crop yields. Here for information broke down information mining method is used. Information mining in agriculture assumes an imperative job in yield assumptions, soil productivity, and plant sicknesses and so on. Farmers can watch information on screen by a website. What's more, farmers will likewise get crop lists dependent on that information which harvests will be possible to yield in that soil.","PeriodicalId":268570,"journal":{"name":"SRPN: Other Sustainable Technology (Topic)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125641659","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 second figure of merit 𝐹2 was calculated for the constructed solar box cooker as 0.285 which is also within the prescribed range of 0.254-0.490m2oC/W, while delay observed in cooking time is attributable to the roughness in the foil, dirt and myth of overcast skies.

Energy can come from fossil or renewable sources. Both require the use of capital, which is also needed in the production of final goods. Renewable energy firms can invest in improving the productivity of their capital stock. The actual improvement is random and subject to spillovers. Productivity improvements by renewable firms require \"scrapping\" some of their existing capital. Together with spill-overs, this leads to under-investment in improving the productivity of renewable energy capital. In the presence of environmental externalities, the optimal allocation can be implemented through a Pigouvian tax on fossil fuel, together with a policy which promotes adaptation of new renewable technologies by taxing firms proportional to their under-scrapping. An implication of our analysis is that it is not optimal to make large investments in new technologies where progress is fast and where current capital becomes obsolete before long. We calibrate the model using world-economy data in order to study the implications of various proposed tax/subsidy scenarios for economic growth.","PeriodicalId":268570,"journal":{"name":"SRPN: Other Sustainable Technology (Topic)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131259069","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}

Building on an economic model of energy technology adoption that features network externality, this paper takes an explicit account of the potential importance of network externality in the design of RET adoption policies. We argue that as incumbent FET has established pervasive deployment and installed base advantages within the existing energy production, distribution and service network, it would create a network externality mechanism that makes it difficult to dislodge the dominant FET-based technological regime, leading to an inertia against the adoption of newly emerging RET even if energy policy regulations have been put in place to eliminate RET’s cost disadvantage. We hence propose that a reformulation of RET policy paradigm should consider extending the traditional scheme centring on eliminating cost gap to a new one that corrects for both cost and network externality gaps.","PeriodicalId":268570,"journal":{"name":"SRPN: Other Sustainable Technology (Topic)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126757185","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}
