Customer Relationship Management (CRM) is an enterprise-wide business strategy directed at attracting, retaining and effectively serving customers to grow up their value over the long term. Because customers differ in their preferences and purchasing habit, and their mobility is enhanced by increasing availability of information, firms invest in technologies that help them gain detailed understanding of their customers, allowing them to know how to respond to customer needs and market products and services more effectively. While the modern CRM strategy is intensive in the use of analytical technologies, the Nigeria supermarket industry still at the first stage of its development phase have largely interacted with customers through personal interaction partly due to the low level of competition for customers, high cost of investment in analytical CRM infrastructure and lack of dynamic capability to integrate technology, people and processes.

Total Innovation Management (TIM) is the system of forming an innovative synergy between technology, organization and culture to build innovation competence in organizations. Supply Chain (SC) is a global network used to deliver products and services from raw materials to end-customers via an engineered flow of information, physical distribution and cash. This paper appraised TIM on SC in the automobile industry in Nigeria using structured questionnaire and interview. The upshot indicated 40% of SC executives are more concerned with risk associated with supply and thus invest in insurance policies. 80% of trained SC staff applies ICT tools in visibility (trackability). All SC staff were receptive to innovative ideas, indicating sustainability of TIM ideology in the sector.

A novel X7475 (Al-Zn-Mg-Cu) alloy was fabricated from recycled beverage cans (RBCs). Al was recovered from RBC. Zn and Mn were sourced from spent batteries, while Cu was sourced from copper wire. The weight percent (wt%) Zn was varied at 4, 4.5 and 5. Following the fabrication of rods, samples were taken through precipitation and artificial ageing at 475 °C and 145 °C respectively. The pin-on disc method within ASTM G99-17 was used for the wear test, while hardness post-mortem was done using ASTM E18 specifications. Wear mass loss (WML) and hardness were optimized using response surface methodology (RSM). The least WML of 0.017 g and maximum hardness of 142 HV were obtained from an alloy fabricated using 5 wt% Zn, when subjected to a load (L) of 30 N, speed (S) of 400 RPM and time (T) of 10 min. The MWL of 0.011 g and least hardness of 71 HV were observed in an alloy of 4 wt% Zn under a load of 20 N, with S, and T at 150 RPM and 6 min apiece. Formation of hardening precipitates like Al 2 CuMg, MgZn 2 and CuAl 2 , were suggested to be responsible for the low WML and hardness observed in the alloys. The result confirmed the significant of the optimization model at a confident interval of 95% (R 2 = 0.9531). Additional experiment was suggested for correlating hardness with tensile strength.

Aluminium (Al) alloys are employed, from aerospace, automotive body panel, building industry to kitchen wares. This paper attempts to close an existing gap in the usage and variation in the percentage weight (% w.t.) of two constituents [Magnesium (Mg) and Copper (Cu)] in Al alloy and evaluate the impact of such variations on yield strength in N/mm 2 and percentage elongation (% e) at ambient temperature. Experimental X7475 alloy was prepared from constituents drawn from 6 % Zn, 2.5 % -3.5 % Mg, 1.8 % -3.0 % Cu, 0.03 % Mn, 0.23 % Cr and Al as balance in all cases. The result revealed that yield strength increased with increase in Mg and decreased with increase in Cu as a maximum yield strength of 384.57 N/mm 2 was displayed by an alloy of 2.5 % Mg, 3.0 % Cu while the least yield strength of 130.00 N/mm 2 was recorded by an alloy of 3.5 % Mg, 3.0 % Cu. Ductility (% e) increased with increase in Cu. The paper submitted that mechanical properties of Al alloys depend not only on the content of alloying elements, but also on their relative chemistries with each other, impact of impurities and heat treatments.
