Ten coordination compounds based on a sulfonated monoazo dye, formulated as M(H(2)O)(2)(4,4'-abs)(2) (M = Mn , Co , Cu , Zn , Cd and Pb ; 4,4'-abs = 4-aminoazobenzene-4'-sulfonic anion), Ag(4,4'-abs) (), [Ln(H(2)O)(phen)(2)(4,4'-abs)(3)].3H(2)O (Ln = Gd , Tb , and Ho ; phen = 1,10-phenanthroline), as well as the parent ligand L [(4,4'-Habs)(2).4H(2)O] and precursor NaL.HL [Na(4,4'-abs)(4,4'-Hab...

Dinoflagellates are the large group of marine phytoplankton with primary studies interest regarding their symbiosis with coral reef and the abilities to form harmful algae blooms (HABs). Toxin produced by dinoflagellates during events of HABs cause severe negative impact both in the economy and health sector. However, attempts to understand the dinoflagellates genomic features are hindered by t...

Harmful Algal Blooms (HABs) are considered a major contributor to membrane biofouling in Seawater Reverse Osmosis (SWRO) desalination plants. The presence of HABs the raw feed water leads an increase fouling rate, chemical consumption, and can cause temporary shutdown Effective pretreatment reduce amount organic foulants reaching RO alleviate problem flux decline during operation frequent clean...

Harmful algal blooms (HABs) present an emerging threat to human and ecosystem health in the Alaskan Arctic. Two HAB toxins are of concern region: saxitoxins (STXs), a family compounds produced by dinoflagellate Alexandrium catenella, domoic acid (DA), multiple species diatom genus Pseudo-nitzschia. These potent neurotoxins cause paralytic amnesic shellfish poisoning, respectively, humans, can a...

Harmful algal blooms (HABs) have a severe impact on human health, aquatic ecosystems, and the economy. There is still lack of effective means to control blooms. Herein, TVP-A, positively charged photosensitizer with aggregation-induced emission (AIE) characteristics introduced as super-efficient, cost-effective, eco-friendly agent for governance HABs. TVP-A efficiently harvests white light gene...

abstract the aim of this study was the identify cyanobacterial flora of rice–fields in dargaz, to interaction between cyanobacteria by culturing in solid medium bg-110 in laboratory was investigated. nostoc piscinale and nostoc spongiaeforme were identified as strongest and weakness species, respectively, regarding secondary metabolits producing (allelochemicals).the algal pairs were classified...

Natural high proliferations of toxin-producing microorganisms in marine and freshwater environments result dreadful consequences at the socioeconomically environmental level due to water seafood contamination. Monitoring programs scientific evidence point harmful algal blooms (HABs) increasing frequency intensity as a global climate alterations. Among toxins, okadaic acid (OA) related dinophysi...

This study used scanning electron microscopy with an backscatter diffraction system to the refinement mechanism of proeutectoid ferrite (Pro-F) and eutectoid (Eut-F) in a D2 wheel steel under rolling contact conditions. The results indicate that as shear strain increased (γ < 0.21), dislocation density continuously, formed cells were distributed uniformly grains. Subsequently, cell boundaries c...

Virtually every coastal country in the world is affected by harmful algal blooms (HABs, commonly called "red tides"). These phenomena are caused by blooms of microscopic algae. Some of these algae are toxic, and can lead to illness and death in humans, fish, seabirds, marine mammals, and other oceanic life, typically as a result of the transfer of toxins through the food web. Sometimes the dire...
