Langmuir–Blodgett (LB) technique has been used to deposit composite multilayers of poly(3-octylthiophene) with cadmium arachidate (POT-CdA), zinc arachidate (POT-ZnA) and copper arachidate (POT-CuA). These composite multilayers were used as precursors to develop the respective semiconducting CdS, ZnS and Cu2S nanoclusters in the POT-arachidic acid (POT-AA) matrix. The formation of sulphide nano...

Telomeres are composed of simple tandem DNA repeats that protect the ends of linear chromosomes from replicative erosion or inappropriate DNA damage response mechanisms. The mammalian Protection Of Telomeres (POT1) protein interacts with single-stranded telomeric DNA and can exert positive and negative effects on telomere length. Of four distinct POT1 homologs in the roundworm Caenorhabditis el...

The low-node pinching order at a high-density plant cultivation system (LN&HD) is now widely adopted for increasing tomato yield and fruit quality. LN&HD period spans 70–120 days, employs the use of small amount substrate (low volume), plants are usually topped between first fourth truss. Using in induces root restriction. Increasing extent restriction pots has been quality some advance...

South Africa has been described as a melting pot of different cultures, adding to the rich South African heritage, boasting eleven official languages. This cultural diversity, however, poses quite a unique challenge for designers of software, especially in the design of e-commerce websites. This paper describes an experiment with the net-generation and the effects of culture on users’ perceptio...

Conducting poly(o-toluidine) (POT) and poly(m-toluidine) (PMT) blends containing 10, 30, 50, 70, and 90 % wt/wt of polystyrene (PSt) were prepared by employing a two-step emulsion pathway. The bands characteristic of both polystyrene and POT/PMT are present in the IR spectra of POT–PSt and PMT–PSt blends. The UV-visible spectra of POT–PSt and PMT–PSt blends exhibit two bands around 313 and 610 ...

Mesembryanthemum crystallinum is considered a drought and saline stress-tolerant plant with many biological activities that has been revalued as cool flavouring plant. The objective of this work was to assess optimum mode cultivation M. produce edible parts under greenhouse conditions. Therefore, three soilless media were evaluated: peat, vermiculite hydroponic culture. Pot culture in peat did ...
