A model for the pavement temperature prediction at specified depth

This paper examines the existing models for predicting pavement temperatures at a certain depth and formulates a new one using the regression equation to predict the minimum and maximum pavement temperatures at the specified depth depending on the surface pavement temperature and its depth

Functional dependency between the logistics security system and the MySAP ERP in metallurgy

MySAP ERP - Enterprise Resource Planning (system - solution which provides a whole set of functions for the business analytics, finance, human resources management, logistics and corporate services) has developed from SAP R/3. It is one of the main products of the SAP AG German multinational company and as such, it is a very important element of the international industrial and technological security system. By defining the functional dependency between the security systems (logistics security systems) and the IT (My SAP ERP) systems in metallurgy, a concept for designing MY SAP ERP system in metallurgic industry is defined, based on the security aspects

Logistic model of the security system in the military industry repair sector

The repair sector is a part of the military industry the establishment of the military combat readiness and thus the establishment of the state security system. This paper deals with the functional dependence of the military industry repair sector and the logistic model of a security system

Chemical composition and antimicrobial activity of Osage orange (Maclura pomifera) leaf extracts

The main goal of this study was to establish the chemical profile of Osage orange (Maclura pomifera) leaf extracts, obtained by conventional maceration technique, and to examine its antimicrobial activity. The identification and quantification of the extract compounds were done using ultra‐high‐performance liquid chromatography, with a diode array detector coupled with triple‐quadrupole mass spectrometer and gas chromatography–mass spectrometry techniques. Thirty‐one polyphenolic compounds were detected and identified in the ethanolic extracts, whereby 5‐O‐caffeoylquinic acid was found to be the dominant compound. Among other compounds, pentacosane and palmitic acid were the most abundant compounds in the dichloromethane extract. The preliminary antimicrobial activity screening shows that Gram‐positive bacteria tend to be more sensitive to the investigated extracts. The highest antimicrobial activity was determined against Enterococcus faecalis ATCC 19433 and Listeria monocytogenes ATCC 35152. From these results, Osage orange leaves can be considered as plant material with significant antimicrobial properties
