These are bosons and fermions, respectively. Particles are divided into subcategories in both of them. A fermion is a particle that has odd half-integer spin, for example, like (frac{1}{2}) , (frac{3}{2}) and so on. Quarks, Leptons, Protons, Neutrons are fermions. Bosons are particles with integer spins such as 0, 1, 2, and so on. For example, Bosons are like Photons, Gluons, W+, W-, Z0 bosons, Higgs bosons, Mesons etc. All matter particles (with mass) are fermions and have a significant amount. All particles that carry force are bosons. In this chapter, I'll illustrate that only fermions interact with space-time and get reversed. In space-time, bosons interact but are not reversed. Anti-particles (fermions) have space-time reversed, but bosons have space-time that is identical. As a result, all matter particles have their anti-particle counterparts, but all force carrying particles do not have their anti-particle counterparts.","PeriodicalId":420684,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 10","volume":"387 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116484738","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}

Mordecai","doi":"10.9734/BPI/CASTR/V10/2069D","DOIUrl":"https://doi.org/10.9734/BPI/CASTR/V10/2069D","url":null,"abstract":"This paper empirically examined the impact of agricultural output on economic development in Nigeria using annual time series data spanning 1986 to 2014. Economic development proxied by per capita income (PCI) was explained by agricultural output (AOUT) and public agricultural expenditure (PXA). The contributions of agriculture to economic growth can be examined through the roles of the sector in the economy.  The study employed the Augmented Dickey-Fuller Unit Root test and the Vector Autoregressive model. The result of the multivariate VAR model indicated that most of the lags of the variables are not significant. However, the high level of the R2 and F value in the VAR regression estimates for PCI gave convincing results that collectively all the lagged terms are statistically significant, implying that agriculture plays an important role in Nigeria’s economic development. The variance decomposition analysis revealed that the greater contribution to shocks in economic development apart from feedback shocks was received from shocks to agriculture. The results of the impulse response function in support of the variance decomposition analysis showed that per capita income responded positively to shocks in agricultural output throughout the ten year period, while the response of PCI to shocks in PXA was negative in the first two year period but became positive throughout the last eight periods. We therefore concluded that agriculture is beneficial and plays a significant role in the development process of Nigerian economy. Hence, the government should increase its expenditure on the sector consistently and ensure that Nigerian economy is diversified, in other words, crude oil should not be the mainstay of Nigerian economy. Also, the government of Nigeria should encourage financial institutions to make certain percentage of their total credit facilities available for the agricultural sector in order to enhance food supply, employment generations, poverty reduction, etc.","PeriodicalId":420684,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 10","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121986666","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}

There is a revolution in India, an anti-corruption wave is growing within Indian civil society; in latest years, people from all walks of life have said: enough is enough, and each in their own way is doing something about it; some are taking to the streets, as we have seen the Jan Lokpal movement under the leadership of Anna Hazaare and his team has truly awakened the entire nation about administrative lawlessness. and They demanded that their suggestions be incorporated into the Lokpal bill, and their effort to live a democratic life has received widespread support. Others are fighting this through the courts, while others have turned to the media., but Still, specific measures are required to combat rising corruption in all sectors; strong and stringent laws must be enacted with teeth and power, leaving no room for the guilty to flee; and firm and strong steps must be taken in the implementation of LOKPAL.","PeriodicalId":420684,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 10","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130340875","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 part of the colony’s production time is spent on each forage site in the period when the crop or wild vegetation covering it is in flower. The total period covered by the sequence of sites, including the base site, must be equal to or less than the duration of the honeybee colony’s annual biological cycle. The migratory beekeeper draws up viable sequences of forage sites and calculates their profitability levels. Variations in the profitability of forage sites which alter the composition of the sequence, affecting provision of the non-marketed ecosystem pollination services impact the biodiversity of the pollinated plants with trickle-down effects on sustainability. \u0000In the case of migratory beekeeper, there is, therefore, a sequential relationship between profitability and sustainability.","PeriodicalId":420684,"journal":{"name":"Current Approaches in Science and Technology Research Vol. 10","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115900959","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}
