The mechanical evaluation of Al7075/ periwinkle ash particulate composites was studied. Al7075/periwinkle ash particulate composites at different weight percentage (2%, 4%, 6% and 8%) of periwinkle ash particles were produced using the stir casting method. The as-cast samples consisting of varied weight percentage of 0, 2, 4, 6, and 8% amount of periwinkle ash particulate were tested for mechanical properties such as hardness and tensile tests andtribological properties such as wear and friction test. The results were compared with the unreinforced sample under the same conditions. It was observed that the addition of periwinkle ash particulate increased the mechanical properties of the alloy composites. The tensile test results showed the 8wt% composite having maximum tensile strength of 493.1 N/mm2while 0wt% (unreinforced alloy) had the least value of 242.55 N/mm2. The hardness was found to be maximum for the 8wt% composite with a value of 77.2 HRB and least with a value of 61.5 HRB for the 0wt% (unreinforced alloy). The wear results showed a lower wear rate and frictional coefficient for the composite compared with the unreinforced alloy. Optical microscopy was used to examine the microstructure of the composites developed and uniform dispersion of the reinforcement was observed in the micrographs. The composites produced has light weight combine with good strength and can be used as bearings for brake disc.

Acquired images for medical and other purposes can be affected by noise from both the equipment used in the capturing or the environment. This can have adverse effect on the information therein. Thus, the need to restore the image to its original state by removing the noise. To effectively remove such noise, pre knowledge of the type of noise model present is necessary. This work explores different noise removal filters by first introducing noise to an image and then applying different spatial domain filtering techniques to the image to get rid of the noise. Different evaluation techniques such as Peak to Signal Noise Ratio(PSNR) and Root Mean Square Error(RMSE) were adopted to determine how effective each filter is on a given image noise. Result showed that some filters are more effective on some noise models than others.

In an era of globalization and rapid technological advancement, the healthcare sector is undergoing profound transformation and increasing complexity. Nursing services are pivotal in this evolving global landscape that must be connected to these dynamic changes. This study probes into the complex interplay of organizational factors and organizational citizenship behaviour, examining the mediating influence of unit management competencies and the moderating role of work experience within a comprehensive theoretical framework. The main purpose of this research is to establish a vigorous theoretical foundation for investigating the impact of organizational factors on organizational citizenship behavior, with specific attention on the mediating role played by unit management competencies among nurses in-charge. This study follows a systematic five-stage approach, commencing with a comprehensive literature review facilitated by the Zotero reference management system and VOS viewer software. This method identifies existing research gaps and clarifies empirical and theoretical associations between various variables. The results were that the blend of existing research led to the formulation of hypotheses and the creation of a refined conceptual framework. Empirical and theoretical evidence substantiated the relationships between four key organizational factors: burnout, work environment, organizational support, interpersonal relationships and organizational citizenship behaviour. This proposed conceptual framework has the potential to be empirically tested within healthcare institutions, thereby expanding our comprehension of these crucial dynamics. Subsequent research in this domain will contribute to a deeper understanding of these critical factors. The findings of this study hold significant implications for nurse managers, hospital administrators, and, ultimately, the welfare of clients and the community at large.
