One of the problems faced in front of industry for potting media is limited amount of quality row materials (mainly peat) for unlimited production of quality substrates in the future. The using of natural minerals for production of substrates or as amendments for existing substrates is possible solution for this problem. The natural zeolites with their specific properties – high CEC, high conte...

The activity of calcium in plaque fluid is needed to calculate the saturation level of that fluid relative to the tooth mineral. One method to determine the calcium activity in very small plaque fluid samples is by micro ion-selective electrode (ISE). Two commercially available calcium ionophores, a neutral-carrier and a charged-carrier, were evaluated in micro ISEs and compared to a commercial...

Abstract Natural sources of antioxidants are plant materials, which include dietary fiber, oligosaccharides, vitamins, and minerals. Fruits vegetables the main natural macro- microelements one popular ingredients for creating functional products that have a regulatory effect on many body systems as whole. The article examines biochemical characteristics fresh fruits in order to highlight most p...

The purpose of this study is twofold: to examine macro (calcium, magnesium, and phosphorus) and trace mineral (iron) concentration in oriental supplements (OS), and to define OS prevalence in elite athletes. Participants of this study were 928 varsity athletes (male: 680, female: 248) with 23 sports types. Recent 3-month dietary supplements (DS) and OS practice was surveyed during training peri...

Many soil functions depend on the distribution of macro(≥ 0.25 mm) and micro(< 0.25 mm) aggregates and open space between aggregates (i.e. soil structure). Despite the importance of macroaggregates in soil, little is understood about how they form and become stable. We hypothesize that biological activities, chemical reactions, and physical forces which help to form macroaggregates differ from ...

Der Beitrag stellt auf Basis einer ersten empirischen Untersuchung den Status Quo des Geschäftsprozessmanagements (GPM) in der kommunalen Wirtschaftsförderung dar. Obwohl GPM in der öffentlichen Verwaltung ein Instrument von wachsender Bedeutung darstellt, wurde der Bereich kommunaler Selbstverwaltung hierzu bislang wissenschaftlich nicht evaluiert. Die vorliegende qualitative Voruntersuchung b...
