The journal welcomes all kind of research/review/abstract papers regarding Engineering subjects including Earth and Planetary Sciences, Environmental Science, Chemical Engineering, Agricultural and Biological Sciences, Renewable Energy, Biochemistry.
A novel spectrophotometry method has been proposed to quantitatively evaluate neomycin sulphate in its pure form and pharmaceutical eye drop preparations. The Hantzsch condensation reaction method was developed by adding trimethylammonium bromide as a surfactant to create a condensed complex with a strong orange color and a high absorption peak at 488 nm wavelength. Beer's law linearity was determined to be between 5 and 125µg/ml in concentration, with a molar absorptivity of 2.89 x103 l/mol.cm, Sandell sensitivity of 0.212 µg/cm2, a limit of quantification of 3.66 µg/ml, and a determinatio

Individuals were divided into insulin-sensitive (group A) and insulin resistance (group B). The study comprised euglycemic non-diabetic individuals with an HbA1C of less than 6.5%. Fasting insulin was done using a competitive enzyme-linked immunosorbent assay (ELISA) technique. Colorime
Read MoreMicroplastics have emerged as a pervasive environmental contaminant, yet the potential risks they pose to human well-being remain poorly understood. Several routes of exposure have been identified, including ingestion, inhalation, and dermal penetration, with the latter warranting equal attention as the former two. Notably, microplastics have been detected in human-derived biological samples, such as excrement, biofluids, and tissues. The majority of toxicological studies on microplastics have relied on laboratory rodents and human-derived cells, revealing potential targets including energy ho
Read MoreThe reduction of quality-related costs has become increasingly important to managers in recent decades, primarily aimed at improving the company's profit. Indeed, a product poor quality generates additional direct and indirect costs, which in turn have negative effects on the profit of the company's shareholders. But what about the costs generated by products on the environment? Are they taken into consideration? The aim of this paper is to contribute to addressing the concept of quality costs (COQ) as a management tool related to the environment within a business. This gap persists despite th

Their structure was identified by FT-IR, 1HNMR, 13CNMR and were screened in vitro anti-microbial for biological activity.
