Analysis of the Application of Nanofluids in the Capture and Utilization of Renewable Energy 

ubbiah Muthuraman,Natarajan Saravanan,Murugan Sivaraj,Ayyappan Kumar
Solar energy is becoming a viable and alternative renewable energy source. The sun generates solar energy, whereas fossil fuels are extracted, which is detrimental to the environment. The availability of fossil fuels is diminishing, although solar energy is plentiful. The utilization of fossil fuels to fulfil our requirements, such as electricity, produces energy applicable to diverse purposes. The combustion of fossil fuels generates detrimental gasses, resulting in air, water, and soil polluti...

Symmetric Theory Omnipresent Medium Planck

Giuseppe Azzarello
In this article, we continue the development of the Symmetric Theory. What we will show is the coupling between the universe and the medium Planck, understood as the medium that formalises the characteristics of the zero-point field. We will show how the phenomena of the infinitely large of the universe and the infinitely small of the atom harmonize in relation to the medium Planck. We will show how Hawking radiation, Unhru effect, Casimir effect, Entropic force, Stefan-Boltzmann’s cons...

Enterprise Network Design and Security Optimization

Kelechi Ikpe,Evans Ashigwuike
Enterprise networks are the backbone of an organization’s ability to communicate and share data. Information Technology Systems (ITS) extends beyond Computers and includes Phone Systems, Fax Machines, Internet of Things (IoT), applications, and other communication and data devices. A large company may have an extensive enterprise network that connects buildings around its headquarters campus with a high-speed network and other prerequisites, thereby making it highly vulnerable to threats and att...

Prevalence and Associated Factors of Cardiac Autonomic Neuropathy Among Diabetic Patients at Bugando Medical Centre, Mwanza, Tanzania

Sabrina Sven Kumlin,Samuel Elias Kalluvya,Eva Mujuni
Introduction: DM has been implicated with multiple complications including diabetic cardiac autonomic neuropathy (DCAN), with a global burden ranging from 1% - 90% in type 1 DM and 20% - 73% in type 2 DM. Poor glycemic control, long duration of DM and traditional cardiovascular risk factors have been associated with the development and progression of DCAN. In Tanzania, there is limited data on DCAN burden and its associated factors. This study was conducted to raise awareness ab...

Impact of Credit Default on the Capital Adequacy Ratio of Quoted Deposit Money Banks in Nigeria

Agbana John,Umar Abbas Ibrahim,Ephraim Adamu Tonga,Arinze-Emefo Ifeyinwa Chinyere
The need for the proper and efficient management of credit default and capital adequacy ratio of the quoted deposit money banks (QDMBs) in Nigeria is urgent. It continues to constitute challenges detrimental to the Nigerian banks’ progress and, by extension, the country’s economy at large. This study, thus, investigates the impact of credit default on the credit adequacy ratio of QDMBs in Nigeria. Thirteen (13) deposit money institutions listed on the Nigerian stock exchange were utilised to acc...

The paper also analyzes the role of Christian missionaries in reshaping cultural and educational institutions, leading to the adoption of new religious and social no...

Another Look at Node Renumbering

Ibrahim F. Khatib
Node renumbering is an important step in the solution of sparse systems of equations. It aims to reduce the bandwidth and profile of the matrix. This allows for the speeding up of the solution of the system or allows for the addressing of even larger systems than otherwise would be possible. Research on this topic dates to the late sixties. In most of these algorithms nodal degree is an important consideration. In the new algorithm, we consider the maximum difference in adjacent node numbers as ...
