Owing to the MAF process’s capabilities for its efficient surface finishing, it is essential to understand the parallel quality of different response parameters and their interdependency. This paper focuses on identifying a relation between surface hardening and roughness induced by the MAF process. In this research work, the influence on micro-hardness from the value of surface roughness has been studied. The different experimental conditions are applied to Ti–6Al–4V specimens treated using a pulsating DC-MAF machining set-up, and Material removal was done using loosely bonded magnetic abrasive media. The surface roughness and microhardness share significant interdependency, represented by a graph showing the best relationship between surface microhardness and roughness.

The current trend of energy supply and its uses are very unstable economically, socially and environmentally. Greenhouse gas emissions are continuing to increase, and it will affect the environment globally. The scope of alternative refrigeration system like vapour absorption (VARS), vapour adsorption and ejector cooling can play significant role in the modern industry with low carbon emission. The experimental setup of 03 Ton of cooling (TR) of dry compression vapour compression refrigeration (VCRS) has been evaluated and compared with single-stage of LiBr-H2O-based VARS cooling system. The operating condition of condenser, evaporator temperature and pressure have been considered for performance analysis of both systems. The higher value of condenser temperature not suitable for efficient cooling and also decreases the energy performance ratio (EPR or COP) of system. The R134a is commercially useful eco-friendly refrigerant but applicable in VCRS (Energy consumption by VCRS is much more than VARS). The employment of VARS have tremendous potential for space cooling and water chilling application at same range of VCRS operating temperature of condenser with low-grade energy source or solar energy utilization. VARS is low carbon emission and non-toxic technology and able to map decarbonize economy for industrial sector.

Food innovation and sustainable development through biotechnology is a new and emerging world order. The Millenium Development Goals’ cardinal objective is eradication of extreme poverty and promotion of good well-being of humanity. Nigeria having evolved a policy with boards to drive this science and technological advancements has not been able to achieve this target optimally as evidenced by other countries globally. There are two major areas of concern which are determining the extent of government involvement in production of food innovation and sustainable development and establishing the relationship between food innovation and sustainable development under a bioeconomy perception in Nigeria. Having regard for the forgoing, the study examines food innovation toward sufficiency and sustainable development. A descriptive paper that looked at experiences across the globe against Nigeria and possible inventions from Agricultural products it can leverage on. It was observed that the right framework, policy, implementation, and drive have not been adopted. It was then submitted that current boards should be strengthened and integrative culturally. Also, a proper application of the triple helix concept that drives new inventions should be upheld.

The entropy generation principle of thermodynamics and statistical methodology have been used in the present work for evaluation of performance parameters of gas turbine–steam turbine (GT-ST)-based combined power generation system and assessment of major losses in components. The mathematical model is carried out for the quantitative analysis of exergy estimation, efficiency of parts in accurate manner. The statistical analysis is also agreed to examine the variations in performance of plant at different operating conditions. This research paper mainly deals with maximum exergy losses which are found in combustion chamber of GT system and exhaust flow system of ST system. The combined and exergetic efficiency of plant is found to be 41% and 38.5%, respectively. The statistical modeling concluded that the comparative results of performance parameters at different compression ratio of combustible gases affect the overall performance of combined GT-ST plant. This study helps to justify possible efficiency improvement with identifying the irreversibilities of plant utilities.
