On the effectiveness of dry drainage in soil salinity control

引用

Science China(Technological Sciences) 2009年第11期52卷 3328-3334页

Dry drainage is thought to be a potential approach to control soil salinity. This study took the Hetao Irrigation District as an example and evaluated the effectiveness of dry drainage by using remote sensing, a conceptual model and a field experiment. Archived remote sensing images from 1973―2006 were used to delineate the temporal and spatial change of soil salinity. The conceptual water and salt balance model was used to evaluate the role of dry drainage in removing excess salt from the irrigated land. The field experiment was performed to get field validation and give more accurate estimation. The results show that dry drainage did contribute to remove excess salt from the irrigated land and succeed in controlling soil salinity in the Hetao Irrigation District. It can be taken as an alternative approach in (semi-)arid area where artificial drainage is not applicable.

Two sides of a coin： host-plant synchrony fitness trade-offs in the population dynamics of the western spruce budworm

引用

Insect Science 2018年第1期25卷 117-126页

作者： Jacques Regniere vincent G. Nealis Natural Resources Canada Canadian Forest Service Laurentian Forestry Centre Quebec Canada Natural Resources Canada Canadian Forest Service Pacific Forestry Centre Victoria British Columbia Canada

Conifer-feeding budworms emerge from overwintering sites as small larvae in early spring, several days before budburst, and mine old needles. These early-emerging larvae suffer considerable mortality during this foraging period as they disperse in search of available, current-year buds. Once buds flush, surviving budworms construct feeding shelters and must complete maturation before fresh host foliage senesces and lignifies later in the summer. Late-developing larvae suffer greater mortality and survivors have lower fecundity when feeding on older foliage. Thus, there is a seasonal trade-off in fitness associated with host synchrony： early-emerging budworms have a greater risk of mortality during spring dispersal but gain better access to the most nutritious foliage, while, on the other hand, late-emerging larvae incur a lower risk during the initial foraging period but must contend with rapidly diminishing resource quality at the end of the feeding period. We investigate the balance that results from these early-season and late-season synchrony fitness trade-offs using the concept of the phenological window. Parameters associated with the variation in the phenological window are used to estimate generational fitness as a function of host-plant synchrony. Because defoliation modifies these relationships, it is also included in the analysis. We show that fitness trade-offs characterizing the phenological window result in a robust synchrony relationship between budworm and host plant over a wide geographic range in southern British Columbia, Canada.

What Do We Really Know about Cellulose Biosynthesis in Higher Plants?

Journal of Integrative Plant Biology 2010年第2期52卷 161-175页

作者： Gea Guerriero Johanna Fugelstad vincent Bulone Division of Glycoscience School of BiotechnologyRoyal Institute of TechnologyAlbaNova University CenterSE-106 91 StockholmSweden

Cellulose biosynthesis is one of the most important biochemical processes in plant biology. Despite the considerable progress made during the last decade, numerous fundamental questions related to this key process in plant development are outstanding. Numerous models have been proposed through the years to explain the detailed molecular events of cellulose biosynthesis. Almost all models integrate solid experimental data with hypotheses on several of the steps involved in the process. Speculative models are most useful to stimulate further research investigations and bring new exciting ideas to the field. However, it is important to keep their hypothetical nature in mind and be aware of the risk that some undemonstrated hypotheses may progressively become admitted. In this review, we discuss the different steps required for cellulose formation and crystallization, and highlight the most important specific aspects that are supported by solid experimental data.

Anti-plane (SH) waves diffraction by an underground semi-circular cavity:analytical solution

Earthquake Engineering and Engineering Vibration 2010年第3期9卷 385-396页

Diffraction of a two-dimensional （2D） semi-circular cavity in a half-space under incident SH-waves is studied using the classic wave function expansion method with a new de-coupling technique. This so-called ＂improved cosine half- range expansion＂ algorithm exhibits an excellent performance in reducing displacement residual errors at two rim points of concern. The governing equations are developed in a manner that minimizes the residues of the boundary conditions. Detailed derivation and analysis procedures as well as truncation of infinite linear governing equations are presented. The semi-circular cavity model presented in this paper, due to its simple profile, is expected to be used in seismic wave propagation studies as a benchmark for examining the accuracies of various analytical or numerical methods for mixed-boundary wave propagation problems.

Molecular Plant 2019年第2期12卷 145-147页

作者： vincent N. Fondong Delaware State University Department of Biological Sciences Dover DE USA

Geminiviruses (family Geminiviridae) are among the most devastating plant pathogens worldwide, causing heavy losses on food and cash crops and representing a threat to global food security and sustainability. These viruses have very compact genomes comprising one (monopartite) or two (bipartite) circular singlestranded DNA (ssDNA) molecules, each ranging from 2.6 to 2.8 kb.

Elucidating the dynamics of polymer transport through nanopores using asymmetric salt concentrations

While notable progress has been made in recent years both experimentally and theoretically in understanding the highly complex dynamics of polymer capture and transport through nanopores,there remains significant disagreement between experimental observation and theoretical prediction that needs to be *** salt concentrations,where the concentrations of ions on each side of the membrane are different,can be used to enhance capture rates and prolong translocation times of electrophoretically driven polymers translocating through a nanopore from the low salt concentration reservoir,which are both attractive features for single-molecule ***,since asymmetric salt concentrations affect the electrophoretic pull inside and outside the pore differently,it also offers a useful control parameter to elucidate the otherwise inseparable physics of the capture and translocation *** this work,we attempt to paint a complete picture of the dynamics of polymer capture and translocation in both symmetric and asymmetric salt concentration conditions by reporting the dependence of multiple translocation metrics on voltage,polymer length,and salt concentration *** asymmetric salt concentration conditions,we experimentally observe the predictions of tension propagation theory,and infer the significant impact of the electric field outside the pore in capturing polymers and in altering polymer conformations prior to translocation.
