A superdiagonal composition is one in which the i-th part or summand of size greater than equal to i. In this paper, we study number palindromic compositions and colored compositions. particular, give generating functions explicit combinatorial formulas involving binomial coefficients Stirling numbers first kind.

Halomorphic (or saline) soils, are characterized by high concentrations of soluble salts or sodium, both. Saline soils have unfavorable agricultural properties but provide the natural habitats for a variety highly specialized plants, animals, and other organisms. It is these special interactions that create typical landscape saline known as “slatina”. The aim this study to assess evaluate geoto...

Effects of bilateral chemical lesions of the medial basal ganglia [lobus parolfactorius (LPO)] were examined in 7- to 14-d-old domestic chicks. Chicks were trained in a color discrimination task, in which the subject had to peck one of the two colored beads associated with rewards that differed in quantity (amount of food) and/or temporal proximity (delay of food delivery from peck). In experim...

Gloger's rule posits that darker birds are found more often in humid environments than in arid ones, especially in the tropics. Accordingly, desert-inhabiting animals tend to be light-colored. This rule is also true for certain mammalian groups, including humans. Gloger's rule is manifested at 2 levels: (1) at the species level (different populations of the same species have different pigmentat...

Wild areas provide a wide array of recreational opportunities in nature, including informal camping. We examined the potential for land degradation associated with campsites accessible by vehicle on margins wild country Central Plateau Tasmania, where alpine and sub-alpine ecosystems numerous glacial periglacial wetlands sit within Tasmanian Wilderness World Heritage Area. There were no integra...

In the present study, silica aerogel- egg shell was synthesized for dye removal of colored wastewater. The nano composite structure was characterized by Fourier transform infrared spectra FTIR and scanning electron microscope SEM.The ability of nano composite absorption was assessed for removal basic violet 16BV16 dye from aqueous solutions and was compared with two other adsorbents such as egg...

There is an almost dogmatic view of the different effects of moderate-level sound stimulation in neonatal vs. adult animals. It is often stated that exposure in neonates results in an expansion of the cortical area that responds to the frequencies present in the sound, being either pure tones or frequency modulated sounds. In contrast, recent findings on stimulating adult animals for a sufficie...

When one thinks of Amazonia, images of large towering trees, dark and humid forests, brightly colored frogs, and smiling native people decorated in paint and feathers come to mind. In addition to engaging public awareness, these popular images are used to raise funds for conservation, to advance green politics, and to promote cultural and ecotourism. They are updated versions of nineteenth cent...
