Research paper thumbnail of REVIEW PAPER: Collaboration of Industry with Academia: The Engine of Industrialisation and Development

Proceedings of the Nigerian Academy of Science, Jul 1, 2021

This paper examined and illuminated with examples the ways and means of creating the environment ... more This paper examined and illuminated with examples the ways and means of creating the environment for science and technology research to flourish. It underpins the creation of virile industrial production base as the trigger for research to plume; and consequently, prescribes the key to a sustainable research funding and mutually benefiting collaboration and symbiotic partnership between the industry and academia.It is shown, using comparative analysis, that a sine qua non for the creation of sustainable industrial base is urgent completion of Ajaokuta, NIOMCO, ALUMCO and making other metals, iron, steel and machine tools companies functional; as this generates spinoff industries, promotes beneficiation of local raw materials, expands manufacturing companies in magnitude and number; thereby create wealth to fund government budget and hence, research. It is further established that having correct policies, institutional and governmental, which include pertinent tax regime with rebate rights; and getting every company of specified grade to have a Research Unit locally in the country, provides needed framework for research and collaboration. It is also noted the effect in reducing cost and saving forex for infrastructures (e.g. rail lines, power, dams, etc.); as such, freeing money to fund intensive research, education, health and municipal services. Hence, unleash the benefits accruable to Industry, Academia, citizens; and the consequence on human development index (HDI) and the country at large.It is concluded, that the issue with Nigeria is not dearth of proficient researchers to do quality cutting-edge research, but lack of environment, wherewithal: industrial production base, policy, legal framework, weak political will and discipline to drive any policy. Ways to obviate these barriers to engender research and collaboration with industry beyond the usual concept of local content are elucidated in the paper

Thereupon, exact closed traveling wave and similarity solutions to the plate solidification problem are obtained for some special cases of timevarying plate surface temperature.

Research paper thumbnail of An effect of a purely dissipative process of microstresses on plane strain gradient plasticity problems

Theoretical and Applied Mechanics, 2018

Anand, A theory of strain gradient plasticity for isotropic, plastically irrotational materials Part I: Small deformations, J. Mech. Phys. Solids 53 (2005), 1624?1649] for an isotropic material undergoing small deformation in the absence of plastic spin. It is assumed that the system of microstresses is purely dissipative, so that the free energy reduces to a function of the elastic strain, while the microstresses are only related to the plastic strain rate and gradient of the plastic strain rate via the constitutive relations. The plane strain problem of the Gurtin?Anand model for a purely dissipative process gives rise to elastic incompressibility. A weak formulation of the flow rule is derived, making the plane strain problem suitable for finite element implementation.

Research paper thumbnail of A theory of strain-gradient plasticity with effect of internal microforce

Theoretical and Applied Mechanics, 2017

The proposed theory is based on a system of microstresses which include a microstress vector consistent with microforce balance; the mechanical form of the second law of thermodynamics which includes work performed by the microstresses during plastic flow; and a constitutive theory that allows the free energy to depend on the elastic strain E??, divergence of plastic strain div E?? and the Burgers tensor G. Substitution of the constitutive relations into the microforce balance leads to a nonlinear partial differential equation in the plastic strain known as flow rule which captures the presence of an additional energetic length scale arising from the accounting of microstress vector. In addition to the flow rule, nonstandard boundary conditions are obtained, and as an aid to finite element solution a variational formulation of the flow rule is ...

It underpins the creation of virile industrial production base as the trigger for research to plume; and consequently, prescribes the key to a sustainable research funding and mutually benefiting collaboration and symbiotic partnership between the industry and academia. It is shown, using comparative analysis, that a sine qua non for the creation of sustainable industrial base is urgent completion of Ajaokuta, NIOMCO, ALUMCO and making other metals, iron, steel and machine tools companies functional; as this generates spinoff industries, promotes beneficiation of local raw materials, expands manufacturing companies in magnitude and number; thereby create wealth to fund government budget and hence, research.
