Weeds As Examples Weeds provide good examples to clarify what is meant by an invasive species because most people have a concept of what constitutes a " weed. " Invasion can be thought of as a process that in our example, a plant must go through to become a successful, yet harmful invader. Several barriers must be overcome for a plant to be considered an invasive weed. Invasive weeds are invasi...

In the present study, a two-step approach for damage prognosis in long trusses is suggested in which the first step deals with locating probable damages by wavelet transform (WT) and static deflection derived from modal data with the intention of declining the subsequent inverse problem variables. Then, in the second step, optimization based model updating method using Artificial Bee Colony (AB...

Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network design model which aims to select the facilities and candidate links in a way that yi...

At this time CDF anticipates the possible use of the following herbicides for invasive weed control and reforestation purposes: Clopyralid, Glyphosate, Imazapyr, Sulfometuron methyl, and Triclopyr. New products, formulations and application techniques may provide better control and improved environmental toxicology profiles. The listed products may prove to be ineffective on a specific species....

Ever-increasing demand for water to irrigate crops, support aquaculture, provide domestic water needs and to protect natural aquatic and riparian habitats has necessitated research to reduce impacts from a parallel increase in invasive aquatic weeds. This paper reviews the past 4-5 years of research by USDA-ARS covering such areas as weed biology, ecology, physiology and management strategies, ...

این آزمایش با استفاده از طرح بلوکهای کامل تصادفی با 8 تیمار و در 3 تکرار با هدف اصلی تعیین دوره بحرانی رقابت علفهای هرز با سیب زمینی در مزرعه مرکز تحقیقات کشاورزی خراسان انجام شد. تیمارها شامل دو گروه 4 تایی بودند. در گروه تیمارهای (weed free) به مدتهای 3، 6، 9 و 12 هفته پس از سبزشدن سیب زمینی، مزرعه عاری از علفهای هرز نگه داشته شد و در گروه تیمارهای (weed infested) به مدتهای 3، 6، 9 و 12 هفته ...

Continued interest in the metabolites of Wedelia trilobata (L.) Hitchc, a notoriously invasive weed in South China, led to the isolation of twenty-six ent-kaurane diterpenoids, including seven new ones 1-7. Their structures and relative configuration were elucidated on the basis of extensive spectroscopic analysis, including 1D- and 2D-NMR experiments. The antimicrobial activities of all isolat...

This paper presents the investigations on the application of evolutionary algorithms particle swarm optimization (PSO) and invasive weed optimization (IWO) to find approximate solutions of optimal control problems. For this purpose, discrete form of the problem is converted to a quasi assignment problem, considering a partition of the time-control space. The approximate optimal control function...

We report the 4.51 Mb draft genome of Pseudomonas sp. strain BMS12, a Gram-negative bacterium in the class of Gammaproteobacteria, isolated from the rhizospheric sediment of Phragmites karka, an invasive weed in Chilika Lake, Odisha, India. The Pseudomonas sp. strain BMS12 is capable of producing proteases and is also an efficient plant growth promoter that can be useful for various phytoremedi...
