3D Bioprinting of Hydrogels and Bone like Composites
No full textHydrogels have emerged as a type of biomaterial with excellent biocompatibility, and they are currently frequently used as cell-laden bioprinting materials. Cellular inkjet printing, laser-assisted bioprinting, stereolithography, and extrusion-based printing have all been
investigated as bioprinting technologies. So far, little attention has been paid to various printing process factors and the correlations between the parameters and printing fidelity. Many factors, such as hydrogel fusion during printing, gravity-induced distortion, and nonuniform extrusion due to changes in printing speed, will have a significant impact on printing resolution during the extrusion-based bioprinting process. It lacks research studies that comprehensively discuss biomaterial printability or the correlations between printing
quality/fidelity and process parameters
MACHINE LEARNING IN NEURODEGENERATIVE DISORDERS
No full textNeurodegenerative disorders were responsible for 272,644 deaths in 2016 along in the US. The government spent $655 billion in 2020 for the direct and indirect medical costs from these diseases. Although experiments have been going on to find the cure for the neurodegenerative diseases, there has not been an efficient way till date to completely cure the diseases. Recently, there have been studies in understanding the cause of the diseases so as to plan for the early detection and treatment of diseases such Alzheimer’s, Parkinson’s disease and motor neuron diseases. Since proteins are the functional backbone of our body, understanding their formation and their relation to disease growth is a subject of interest. This is a study to link the application of a few methods developed in recent times to predict the presence of neurodegenerative diseases

The Effect of Economic Freedom on Economic Growth: A Reexamination
No full textNumerous studies have attempted to uncover the nature of the relationship between economic growth and various measures of legal, financial and political institutions. One of the fundamental questions is this: does economic freedom lead to economic growth? Skepticism about the economic performance of democratic institutions is as old as democracy itself. One school of thought argues that democracy can be a constraint on economic growth. According to this school, more political rights do not translate into growth (Robert Barro, 1997). The evidence from the literature has been mixed. A review paper by Gering et al. (2005) concludes that the net effect of democracy on growth performance cross-nationally over the last five decades is negative or null. A recent paper by Acemoglu et al. (2019) provides evidence that democracy has a positive effect on GDP per capita. Its baseline results show that democratizations increase GDP per captia by about 20% in the long run. Brik et al (2020) show that increases, but not the levels, in economic freedom are related to economic growth. Empirical studies on the effect of political institutions on GDP face several challenges such as the issue of measurement error and missing variables. This study contributes to the literature by using most recent data to examine the relationship between economic growth and economic freedom. It shows that improvement in economic freedom leads to positive economic growth
The Impact of Blockchain and Algorithm on FinTech
No full textThe dawn of the 21st century have witnessed the emergence of several technologies targeting the financial sector. The FinTech industry is gradually maturing and covers an array of financial services on the global economy (Laidroo, Koroleva et al. 2021). However, it is needless to state that FinTech is still at its early stage of development. This research explores and highlight the great profitability FinTech has on all asset class and the abundance it gives on the return on investment. FinTech and Blockchain are prevalent topics among technology leaders in finance today. Algorithms govern the peer to peer decentralized network using machine learning techniques. This is owed to the advancement in processor pace and ample data gives room to more financial analysis
Scalability: One Of The Main Challenges Of a Blockchain
No full textBlockchain is a distributed peer-to-peer network, which is connected using nodes throughout the globe. Each node has a transactions ledge, which maintains the whole record of transactions. In blockchain data is stored electronically in digital format which is amazing. A database ordinarily stores its data in tables, whereas in blockchain data is stored in chunks as referred by its name blocks. They are better for maintaining secure and decentralized transactions because in blockchain blocks are connected as a single network. In blockchain transactions can be done between two parties without the involvement of a third party, which means one can maintain their own money without depending on others. Bitcoin is one of application of blockchain, where bitcoin goes through many confirmations on the blockchain before it is cleared because the unconfirmed transaction can be reversed or crypto-currency can be spend twice. Average confirmation time on bitcoin network for a BTC payment is about 10 minutes, which seriously needs be scaled for real-time applications
THE IMPACT OF POLITICAL INFLUENCE ON ECONOMIC DEVELOPMENT IN NIGERIA
No full textAfrica, the cradle of humankind, has excellent economic development potential due to a rich supply of mineral resources and agricultural productivity. Studies indicate that in the early-1970s, the median income of resource-ample developing countries was estimated at 50% higher than countries whose resources were deemed poor (Auty, 2008). Therefore, countries with abundant or ample resources had a profitable additional investment and import resources through commodity rent. Nigeria is Africa's most populated country, ranked second in oil reserves. In addition to the oil reserves, which are ranked eighth worldwide, Nigeria also has a large productive agricultural land regarded as 10th worldwide. Despite the wealth in mineral resources, in terms of economic development, Nigeria still suffers a low gross domestic development (GDP) per capita of around $ 2100, thus ranking below the top 200 worldwide (World-Bank, 2020). Nigeria has a poverty rate of about 70% and a life expectancy of around 50yrs, making it among the poorest country per capita worldwide (Bouchat, 2013). Scholars highlighted a significant factor as the cause of instability in the Nigerian Economy is the corrupt practices of political leaders in public offices. According to Seteolu (2005), political offices are seen as a means for acquiring wealth; thus, they misuse their offices for financial gain (Agwu, 2011). This study discusses the impact of politics on the Economy of Nigeria
Foreign Currency Reserve & Function United States, Russia, and China
No full textIn October 1959, a Yale professor sat in front of Congress’ Joint Economic Committee and calmly announced that the Bretton Woods system was doomed. The dollar could not survive as the world’s reserve currency without requiring the US to run ever-growing deficits. This dismal scientist was Robert Triffin, and he was right. The Bretton Woods system collapsed in 1971, and today the dollar’s role as the reserve currency has the US running the largest current deficit in the world
