Abstract The development of efficient green light-emitting diodes (LEDs) is of paramount importance for the realization of colour-mixing white LEDs with a high luminous efficiency.While the insertion of an InGaN/GaN superlattice (SL) with a lower In content before the growth of InGaN/GaN multiple quantum wells (MQWs) is known to increase the effici

Recently, Kim-Kim introduced the truncated degenerate Bell polynomials and numbers.In this paper, we introduce the truncated Lah-Bell polynomials and numbers.We obtain some identities, recurrence relations read more and properties.Furthermore, we also introduce the truncated modified Lah-Bell polynomials and numbers, truncated degenerate Lah-Bell p

This experiment investigated the effect of number of visual demonstrations on the acquisition of discreet motor skill.Seventy-four college here students of both sex participated in this study.The participants observed a visual model twice or ten times.In the acquisition phase, the participants were asked to throw a dart with postero-anterior moveme

In this paper we show that certain consonants have the effect of depressing the tone on adjacent vowels in Malawian CiTonga, a Bantu read more language spoken mainly in Nkhata Bay.We argue that some of these effects are phonological, changing High vowels to Low.In other cases the effect is not categorical, but gradient, as certain consonants have a

Jordanians live in compact cities with limited green spaces causing several environmental problems that deteriorate the urban quality of life.Many reports and studies demonstrate the benefits of urban green infrastructure (UGI) in overcoming environmental deterioration in compacted cities.Nevertheless, Urban Green Infrastructure is still lagging in
