The 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.
Read MoreFetuin-A, also known as α2-HS-glycoprotein (AHSG), is a multifunctional glycoprotein produced largely in the liver. The reversible binding of Fetuin-A to the insulin-receptor tyrosine kinase inhibits the insulin-induced downstream signal flow, increasing insulin resistance. Adult and embryonic hepatocytes express it more than adipocytes and monocytes do. Fetuin-A has numerous physiological and pathological functions and binds to a variety of receptors. It regulates calcium metabolism and insulin signaling. Examine the relationship between serum fetuin-A levels and the presence or severity of
Read MoreThe use of computational chemistry as an effective means of designing eco-friendly organic corrosion inhibitors has been greatly enhanced by the development of Density Functional Theory (DFT). In this study, the inhibitory activity of benzothiazole and derivatives, was analyzed by this theory. The quantum chemical parameters/descriptors calculated using DFT at B3LYP/6-31G(d,p) level were used to show their inhibition properties in the copper corrosion. Quantum chemical parameters such as E_HOMO (highest occupied molecular orbital energy), E_LUMO (lowest unoccupied molecular orbital energy), en

Electromagnetic control of the electron beams provides scanned intensity modulation which is not possible with photon beams during radiotherapy. This study calculated the stopping power of high-energy (50-250MeV) electrons used in radiotherapy applications in Water, Blood, and Skin(ICRP). Stopping power for electrons is calculated using the eq(10) and Semi-empirical eq(12), then compared with experimental results obtained using the program Estar. Total mass-stopping
