Summary: The synthesis of azoalkanes such as azocyclohexane (1) and 4,4′‐bis(cyclohexylazocyclohexyl)methane (2) and their use as flame retardants in polymeric substrates is reported. For the first time it is demonstrated that azoalkanes alone can effectively provide flame retardancy and self‐extinguishing properties to poly(propylene) films at a very low concentration of 0.25 to 0.5 wt.‐%. All the poly(propylene) formulations passed DIN 4102‐1/B2 standards and the instant azoalkane‐containing poly(propylene) blends show no discoloration.

Aim To assess the role of the Balkan Peninsula as a Pleistocene refugium for the smooth newt, Lissotriton vulgaris, and to test whether its genetic differentiation is temporally compatible with the southern refugia model. Location The Balkan Peninsula. Methods Phylogeographical analyses were conducted using mitochondrial DNA (mtDNA) sequences sampled from 49 populations of L. vulgaris. A fossil‐calibrated estimate of divergence times among major mtDNA clades was obtained. Results We detected seven parapatrically distributed mtDNA clades with very little admixture among populations. Whereas most clades diverged in the Pleistocene, the earliest splits between Caucasian, Anatolian and Balkan clades occurred in the Pliocene. Clades C, D, K and M have local distributions within the Balkans and have evolved in isolation from other groups. Clade L originated in the Pannonian Basin and northern margin of the Balkan Peninsula and recently expanded across central and western Europe. Clades H and E have recently arrived in the Balkans from source populations in the Apennine Peninsula and Anatolia, respectively. Main conclusions The history of L. vulgaris involves multiple, independent refugial populations in the Balkans. Only one of them, located at the northern periphery of the peninsula, showed evidence of post‐glacial expansion into western and northern Europe. The Balkans have therefore served as a reservoir of old diversity for L. vulgaris. By contrast, populations at the northern and eastern frontiers of the peninsula have experienced non‐equilibrium dynamics. Our dating revealed that very little, if any, pre‐Pliocene genetic diversity has survived in Europe, despite an extensive fossil record for this species in the Miocene and Pliocene. Differentiation of the European mtDNA clades thus seems to have been primarily moulded by Pleistocene climate change. None of the currently recognized subspecies present in the Balkans are reciprocally monophyletic in their mtDNA. We hypothesize that incomplete lineage sorting and mtDNA introgression account for the observed discrepancies.

“…While the economic impacts of a college or university are varied and far-reaching, they can be considered as either effects on knowledge creation, research and development, or as effects of the direct and indirect expenditures flowing into the surrounding economy (Stokes & Coomes, 1998). Institutional studies have been conducted to illuminate the former impact and thus describe the economic effects of the transmission and discovery of knowledge and ideas, conducting pure and applied research, and the development of new technologies and industries (Ohme, 2003). While these studies estimate the effect on the labor market in both the short-term and long-term, other studies investigate the latter effects of economic impact created by the institution's pur-chasing of goods and services from within its local economy (Parsons & Griffiths, 2003).…”

Muadzam Shah is a small town in Rompin District, Pahang, Malaysia, established in 1979 by the South-East Pahang Development Authority (DARA). It is a quiet and tranquil agricultural based economy area and is a brainchild of Malaysia's second Prime Minister Tun Abdul Razak. The advent of University Tenaga Nasional in 2001 had changed the landscape of the local economy. Following the concept of "Town University", UNITEN has successfully contributed to amplify the local economy into a greater level, from the oil-palm industry area to a multi-sectoral economy such as retailing sector, food industries, hospitality as well as healthcare industry. Besides, UNITEN also serves as a medium of community and intellectual development between the academia and the society. By adopting Leontief inputoutput approach, this paper is designed to determine the economic multiplier effect that students and faculty staffs have on the local economy and community in Muadzam Shah.
