in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...

Abstract Diffuse coplanar surface barrier discharge (DCSBD) was used to activate the opposite side of plasma‐exposed linear low‐density polyethylene/polyamide (LLDPE/PA) tubular film multilayer casing. We determined that conductive metal rubber roller in DCSBD system allowed formation microfilaments perpendicular surface, resulting improved wettability and adhesion inner LLDPE film. These findi...

Three consecutive years of field experiments were carried out to investigate the effect of root temperatures induced by the application of mulches for phytoextraction of As, Ag, Cr and Sb using potato plants (roots, tubers, stems and leaflets). Four different plastic covers were used (T1: transparent polyethylene; T2: white polyethylene; T3: white and black coextruded polyethylene; and T4: blac...

Three consecutive years of field experiments were carried out to investigate the effect of different root temperatures, induced by the application of mulches on the concentration of sulfur (S) forms (organic-S, total-S and SO4(2-)) and Se in different organs of potato plants (roots, tubers, stems and leaves). Four different plastic covers were used (T1: transparent polyethylene; T2: white polye...

Three consecutive years of field experiments were conducted to investigate how different root-zone temperatures, manipulated by using different mulches, affect the phytoextraction of Ba, Cl, Sn, Pt and Rb in different organs of potato plants (roots, tubers, stems and leaves). Four different plastic covers were used (T1: transparent polyethylene; T2: white polyethylene; T3: white and black coext...

Polymeric multifilaments have gained a significant interest in recent decades. In the studies of mechanical characteristics, although there are different types tests, such as rupture, abrasion, creep, impact and fatigue, it can be said that main characterisation is tensile rupture strength (Yarn Break Load, YBL), which also serves parameter for other tests. The objective this work to evaluate r...

The effect of different root zone temperatures on the concentration and content of B and Al in potato plants was examined using four different treatments of plastic mulches: T1: transparent polyethylene; T2: white polyethylene; T3: coextruded black and white polyethylene; T4: black polyethylene. An open-air treatment (T0) was used as control. The results showed significantly positive effects of...
