We study ED TOL-systems with terminal alphabet in which all words derivated from the axiom countain a bounded number of occurrences of non-terminals. We define, also, unary operators associated with these systems.

The mechanisms underlying the acute neurophysiological and behavioral effects of volatile organic compounds (VOCs) remain to be elucidated. However, the function of neuronal ion channels is perturbed by VOCs. The present study examined effects of toluene (TOL), trichloroethylene (TCE), and perchloroethylene (PERC) on whole-cell calcium current (ICa) in nerve growth factor-differentiated pheochr...

The xylABC operon on the TOL plasmid directs the synthesis of enzymes for conversion of toluene to benzoate and is positively controlled by the regulatory gene xylR. In the study here the nucleotide sequence was determined for the regulatory region of this operon. The in vivo transcription initiation site of the operon was determined by S1 nuclease and reverse transcriptase mapping. RNA was pre...

In clinical and experimental settings, planning ability is typically assessed using the Tower of London (ToL) or one of its variants. For enhancing the comparability across studies, a common ToL problem set was recently suggested comprising a collection of 4- to 7-move problems. Based on previous theoretical and empirical analyses of problem space and task structure, development of the problem ...

Climate change is affecting the tourism industry through many different mechanisms (Weaver 2011;Gössling, 2002, 2007; Berrittella et al. 2005; Hall and Higham 2005; Peeters 2005; Dubois and Ceron 2006; Becken and Hay 2007; Buckley 2008; UNWTO-UNEP-WMO 2008;Gössling et al. 2009). These include: environmental changes and human responses at tourist destinations and countries of origin (Koenig and ...

The Tol-Pal system of gram-negative bacteria is composed of five proteins. TolA, TolQ, and TolR are inner membrane proteins, TolB is a periplasmic protein, and Pal, the peptidoglycan-associated lipoprotein, is anchored to the outer membrane. In this study, the roles of Pal and major lipoprotein Lpp were compared in Escherichia coli. lpp and tol-pal mutations have previously been found to pertur...

BACKGROUND Vapor–liquid and liquid–liquid equilibria of unsaturated saturated hydrocarbons with the bio-based solvent dihydrolevoglucosenone, trademarked as Cyrene, have been reported recently, aiming at utilization in extraction (LLX) extractive distillation (ED). In this work, for a model system comprised methylcyclohexane (MCH) toluene (TOL), both LLX-based ED-based processes were compared o...

Pembangunan infrastruktur Jalan Tol Padang-Pekanbaru sedang gencar dilakukan. Permasalahan pembangunan bermula pada proses pengadaan lahan yang lambat dimana negosiasi tidak berjalan lancar. Penelitian ini bertujuan untuk mengetahui faktor penyebab antara pemerintah dan warga setempat dalam ruas jalan tol Padang-Sicincin lancar serta mencari solusi agar dapat memaksimalkan sumber daya ada. Hasi...
