Aims of research.The use, design and analysis of architectural and building structures in the form of smooth and composite surfaces have become relevant and in demand lately, which determined the purpose of this article - to analyze the use of analytical surfaces given vector, parametric or explicit equations in real structures.Methods.The relation
We used large samples of expressed sequence tags to characterize the patterns of codon Knee Pad usage bias (CUB) in seven different Citrus species and to analyze their evolutionary effect on selection and base composition.We found that A- and T-ending codons are predominant in Citrus species.Next, we identified 21 codons for 18 different amino acid
Objectives: To evaluate compliance with the self-regulation agreement of the food and drink vending machine sector in primary schools in Madrid, Spain.Methods: Cross-sectional study of the prevalence of vending machines in 558 primary schools in 2008.Using the directory of all registered primary schools in Madrid, we identified the presence of mach
Background: There are no current consensus guidelines that address screening patients who may have occult major venous injury in the setting of penetrating thigh trauma.Yet, such injuries confer significant morbidity and mortality to trauma patients if left untreated.Methods: This paper examines the cases of three patients who presented to our sing
The quantum superposition principle has been extensively utilized in the quantum mechanical description of bonding phenomenon.It explains the emergence of delocalized molecular orbitals and provides a recipe for the construction of near-exact electronic wavefunctions.On the other Facial Moisturiser hand, its existence in composite systems may give
