A distributed air pollutant dry deposition modeling system was developed with a geographic information system (GIS) to enhance the functionality of i-Tree Eco (i-Tree, 2011). With the developed system, temperature, leaf area index (LAI) and air pollutant concentration in a spatially distributed form can be estimated, and based on these and other input variables, dry deposition of carbon monoxid...
Eco-exergy and emergy based self-organization of three forest plantations in lower subtropical China
The bio-thermodynamic structures of a mixed native species plantation, a conifer plantation and an Acacia mangium plantation in Southern China were quantified over a period of 15 years based on eco-exergy methods. The efficiencies of structural development and maintenance were quantified through an integrated application of eco-exergy and emergy methods. The results showed that the storage of e...
Unique fragments of adenovirus type 2 DNA generated by cleavage with endonuclease R-Eco RI or endonuclease R-Hsu I (Hin dIII) were used to map cytoplasmic viral RNAs transcribed early in productive infection. Radioactive early viral RNA was first fractionated by polyacrylamide gel electrophoresis. Eluted viral RNAs were then tested for hybrid formation with DNA fragments. The Eco RI DNA fragmen...
مطالعات مقایسه ای از توالی های rdna به منظور بررسی روابط فیلوژنی در محدوده وسیعی از سطوح تاکسونومی مورد استفاده قرار می گیرند. نواحی its و فواصل داخل ژنی dna ریبوزومی هسته ای، واحد های تکراری تکامل یافته ثابت می باشند و ممکن است در بین گونه های داخل یک جنس یا در بین افراد یک جمعیت متغیر باشند. مقایسه توالی نواحی its به طور وسیعی در تاکسونومی و فیلوژنی مولکولی به کار برده می شود به دلیل اینکه دا...
A methodology to generate spatially continuous fields of tree heights with an optimized Allometric Scaling and Resource Limitations (ASRL) model is reported in this first of a multi-part series of articles. Model optimization is performed with the Geoscience Laser Altimeter System (GLAS) waveform data. This methodology is demonstrated by mapping tree heights over forested lands in the continent...
The paper presents a CAT generation algorithm for Dyck paths with fixed length n. It is the formalization of a method for the exhaustive generation of these paths which can be described by two equivalent strategies. The former uses a rooted tree, the latter lists the paths and provides a visit of the nodes of the tree, basing on three simple operations. These constructions are strictly connecte...
