RECOVERY OF CR FROM CHROME-CONTAINING LEATHER WASTES TO DEVELOP ALUMINUM-BASED COMPOSITE MATERIAL ALONG WITH AL2O3 CERAMIC PARTICLES: AN INGENIOUS APPROACH

Leather industries cause soil pollution in terms of leather wastes.Chrome-containing leather wastes (CCLW) also cause various types of pollutions such as air and soil pollution.The utilization of CCLW in the development of aluminum-based composite is the emerging area in the synthesis of materials.In this study, chromium(Cr) in the form of collagen

Perkembangan motorik pada lansia merupakan aspek penting yang mempengaruhi kualitas hidup dan kemandirian individu di usia senja.Penelitian ini bertujuan untuk menganalisis faktor-faktor psikologis dan sosial yang berkontribusi terhadap perkembangan motorik here lansia.Metode yang digunakan dalam penelitian ini adalah pendekatan kualitatif dengan t

A fundamental assumption of avian survival analysis is that the act of capture, handling, and marking birds does not affect subsequent survival.This assumption is violated when animals experience injury, physiological stress, or disorientation during capture and handling that increases their mortality risk following release.Such capture-related eff

The increasing use of modern power electronics raises the issue of harmonics in power systems which ultimately deteriorate its optimal performance in terms of: increased power loss, breaker failure and mal-operation of equipment.It has been found that the most severe harmonics in the system are odd ones due to their unsymmetrical nature.This work p
