The development of scaly buds (= cataphylls) has been traditionally associated with seasonally cold climates, although only few species from the southern hemisphere were investigated in this regard. present work focuses on apical and axillary seven tree native to South-American Temperate Rainforests (STR). Due differences lineages which these derived, high levels inter-specific variation bud st...

The Neanderthal taxonomic position is a matter of wide disagreement among paleoanthropologists. Some workers consider this fossil human group to represent a different species, Homo neanderthalensis, while others see it as a subspecies of Homo sapiens. This study developed two models of morphological variation to be applied to a comparison between Neanderthals and modern humans: modern human pop...

background and objective: oxidative stress plays an important role in the pathogensis of various diseases, including lung cancer, chronic obstructive pulmonary disease, and atherosclerosis. total antioxidant capacity plays a significant role in the body’s antioxidant defense, so its assessment is a matter of the utmost importance. currently, assessment of this capacity is performed in various s...

objective(s) developing and validating a simple, efficient, reproducible and economic reversed phase high performance liquid chromatographic (rp-hplc) method for the quantitative determination of pefloxacin in bulk material, tablets and in human plasma. materials and methods a shim-pack clc-ods column and a mobile phase constituting acetonitrile: 0.025 m phosphoric acid solution (13:87 v/v, ph ...

Imaging spectroscopy is a burgeoning tool for understanding ecosystem functioning on large spatial scales, yet the application of this technology to assess intra-specific trait variation across environmental gradients has been poorly tested. Selection specific genotypes via filtering plays an important role in driving and thus functional diversity space time, but relative contributions species ...

Pronunciation in spontaneous Mandarin speech tends to be much more variable than in read speech. In current recognition systems, pronunciation dictionaries usually only contain one standard pronunciation for each word, so that the amount of variability that can be modelled is very limited. Most recent research work for modelling variations in spontaneous speech focuses on the lexicon level, whi...

This paper proposes a new integrative view of manufacturing cell formation and both inter-cell and intra-cell layout problems. Cells formation and their popular bi-directional linear layout are determined simultaneously through a Dynamic Programming algorithm (with the objective of minimizing the inter-cell flow cost under a cell size constraint). This Dynamic Programming algorithm is implement...
