Soil carbon and nitrogen contents play an important role in sustaining soil physical and chemical quality and help to have healthy environments. The continues conversion of rangelands to arable lands has the potential to change carbon and nitrogen sequestration. In this study to evaluate the effects of land use change on soil organic carbon and nitrogen stock, forty samples collected from north...

Evidence is presented to suggest that, in three dimensions, spherical 6-designs with N points exist for N = 24, 26, ≥ 28; 7-designs for N = 24, 30, 32, 34, ≥ 36; 8-designs for N = 36, 40, 42, ≥ 44; 9-designs for N = 48, 50, 52, ≥ 54; 10-designs for N = 60, 62, ≥ 64; 11-designs for N = 70, 72, ≥ 74; and 12-designs for N = 84, ≥ 86. The existence of some of these designs is established analytical...

Inspired by the “generalized t-designs” defined by Cameron [P. J. Cameron, A generalisation of t-designs, Discrete Math. 309 (2009), 4835–4842], we define a new class of combinatorial designs which simultaneously provide a generalization of both covering designs and covering arrays. We then obtain a number of bounds on the minimum sizes of these designs, and describe some methods of constructin...

—Little information exists on nesting by seabirds and coastal waterbirds in Panamá. The present study of the Gulf of Chiriquí complements our previous study of nesting waterbirds of the Gulf of Panamá. In April 2012, about 4,000 nests of seven species of seabirds and other colonial waterbirds were identified during a complete survey by small plane and boat within and adjacent to the Gulf of Chi...

Abstract This study is the first that worked on temporal and spatial distributions of annual rainfall (Pyear) maximum 24-h (Pmax24h) in Semnan province. For this purpose, different statistical were used to estimate Pyear Pmax24h Six synoptic stations across province studied all had complete data. Different return periods studied. The goodness fit test for showed about 67% follow Generalized Par...

The implement of knowledge sharing in University Town facilitates to aggregate education resource and improve overall strength of University Town. According to factors and performance of teaching knowledge sharing in University Town, the model and theoretical hypothesis of teaching knowledge sharing in University Town are proposed. Questionnaire and structural equation model are used to empiric...
