Weak convergence for variational inequalities with inertial-type method

Weak convergence of inertial iterative method for solving variational inequalities is the focus of this paper. The cost function is assumed to be non-Lipschitz and monotone. We propose a projection-type method with inertial terms and give weak convergence analysis under appropriate conditions. Some test results are performed and compared with relevant methods in the literature to show the efficiency and advantages given by our proposed methods

PRODUCT INNOVATION, A SURVIVAL STRATEGY FOR SMALL AND MEDIUM ENTERPRISES IN NIGERIA

The study investigated how product innovation, as a strategy, enhances the survival of the small and medium enterprises in Nigeria, using Prodco Foods Nigeria Limited as a study. Among the objectives set out were the relationship between product innovation and the survival of Small and Medium Enterpries (SMEs), changes in tastes and preference of consumers necessitating product innovation, and whether product innovation increases sales volume of SMEs. The research study was developed around the product innovative and dynamic capability innovative theories. The theoretical model of the product life-cycle was used in developing the three hypotheses that were tested at 0.05 significant levels; through the survey of one hundred and forty respondents. Copies of the questionnaire were administered to the respondents sampled. The validity and reliability of the instrument were measured at Cronbach’s alpha of 0.63 and alternative form validity of 0.59. The findings revealed that there is a significant relationship between product innovation and the survival of SMEs, also, that changes in tastes and preference of consumers necessitate product innovation, and that product innovation increases sales volume of SMEs. The conclusion from the research findings showed that there is need for SMEs to carry out research on product innovation; in other to meet and fulfill the demand and expectations of all consumers and the market. It was recommended that adequate finance, condusive environment, and public policy framework should be developed by the Nigerian governments to support and encourage the SMEs

PRODUCT DIFFERENTIATION: A TOOL OF COMPETITIVE ADVANTAGE AND OPTIMAL ORGANIZATIONAL PERFORMANCE (A STUDY OF UNILEVER NIGERIA PLC)

In recent years the concept of competitive advantage has taken centre stage in discussions of business strategy; that is why, one of the major challenges organizations face today is how to have a competitive advantage. In most cases a stand out product will do the job, since products are perceived as both highly relevant and meaningfully, the ability for any one product to standout in a competitive category will guarantee the success of such organization. While there are numerous ways to differentiate brands, identifying meaningful product-driven differentiators can be especially fruitful in gaining and sustaining a competitive advantage. Differentiation is when a firm or brand outperforms rival brands in the provision of a feature(s) such that it faces reduced sensitivity for other features (Sharp & Dawes, 2001). Even in industrial economics, a discipline where there is more of a tradition of providing formal statements of theoretical concepts, two eminent industrial economists felt obligated to write an article for the Journal of Industrial Economics titled "What is Product Differentiation, Really?" (Caves and Williamson, 1985)

A Robust Numerical Scheme for Solving Riesz-Tempered Fractional Reaction-Diffusion Equations

The Fractional Diffusion Equation (FDE) is a mathematical model that describes anomalous transport phenomena characterized by non-local and long-range dependencies which deviate from the traditional behavior of diffusion. Solving this equation numerically is challenging due to the need to discretize complicated integral operators which increase the computational costs. These complexities are exacerbated by nonlinear source terms, nonsmooth data and irregular domains. In this study, we propose a second order Exponential Time Differencing Finite Element Method (ETD-RDP-FEM) to efficiently solve nonlinear FDE, posed in irregular domains. This approach discretizes matrix exponentials using a rational function with real and distinct poles, resulting in an L-stable scheme that damps spurious oscillations caused by non-smooth initial data. The method is shown to outperform existing second-order methods for FDEs with a higher accuracy and faster computational time.Comment: 26 page

Effect of drinking magnetized water on immunity and carcass quality of broiler chicken

This study was conducted to determine the effect of drinking Magnetized Water (MW) on the immunity of broiler chicken. The problem which this study focused on was the mortality rate of broiler chicken which is common in some poultry farms in Nigeria due to some factors that could lead to loss of income. There is a need for economical methods for boosting the immunity of Broiler Chicken (BC) in order to reduce the mortality rate. BC (Arbor Acres breed) was given MW. The magnetized water was produced by passing water through the magnetic field in a pipe. The treatments were MW treated for 33s by passing the water through pipe surrounded with magnets one time(T1), MW treated for 66 s by flowing twice through the magnetic unit (T2), T3 was MW treated for 99 s and control (Non-Magnetized Water, NMW, T0). A total of 80 BCs (day old) with 20 BC for each treatment were given MW (T1, T2 and T3), NMW and monitored for 7 weeks. Blood samples were collected for hematology and analyzed using standard methods. The values of white blood cell for T0, T1, T2 and T3 were 153.61×10-9/L, 133.20×10-9/L, 134.78×10-9/L and 101.12×10-9/L and for lymphocytes, were 137.08×10-9/L, 120.79×10-9/L, 125.49×10-9/L and 96.12×10-9/L, respectively. MW T1, T2 and T3 increased body weight gain of the BC by 410, 320 and 210g/broiler. Protein contents of the carcass for T1, T2, T3 and T0 were 13.13%, 13.23%, 13.18% and 12.80%, respectively. MW can therefore enhance production of healthy broiler chickens

Report of Mixed Infection of Infectious Bursal Disease and Chicken Infectious Anaemia Viruses

Infectious bursa disease (IBD) was tentatively diagnosed from an experimental cockerel flock. Clinical signs observed included dullness, diarrhoea characterized by greenish yellow colour and spiking mortality lasting four days. Post-mortem examination results showed pale and slightly enlarged liver and kidney, enlarged and haemorrhagic bursa, petechia haemorrhages on the spleen, keel and thigh muscles and thymus atrophy. Pale liver, thymus atrophy and haemorrhages in the bursa could also be presented in Chicken Infectious Anaemia (CIA) infection. The organs (Bursa, kidney, thymus and liver) from where the infected birds were further screened for IBD and CIA viruses using the polymerase chain reaction technique and were positive for both. This confirms IBD and CIA are responsible for the losses in the flock. This implies that many CIA infections or its mixed infection may be mistaken for IBD alone if no confirmatory diagnosis is carried out, since most post-mortem lesions presenting extensive syndrome are considered to be caused by IBD. &nbsp
