Summary We have identified the tomato I gene for resistance to Fusarium wilt fungus oxysporum f. sp. lycopersici ( Fol ) and show that it encodes a membrane‐anchored leucine‐rich repeat receptor‐like protein LRR ‐ RLP ). Unlike most other genes involved in plant defence, is not member of cluster contains introns its coding sequence. The loopout domain larger than those s, with distinct composition rich serine threonine residues. also lacks basic cytosolic domain. Instead, this aromatic...

The chemical compositions of late Miocene - Pleistocene basalts in Phu Quy island defines two major geochemical groups that reflect the formation and development island. early low alkaline, TiO2 P2O5, high SiO2 group, comprising olivine tholeiitic basalts, forms base later TiO2, produced by central-type volcanic eruptions consisting alkaline overlies eruptive group. Crustal contamination may be expressed positive correlation between Ba/Nb SiO2, which are higher possibly reflecting...

Study of petrological and geochemical characteristics mantle peridotite xenoliths in Pliocene alkaline basalt Nghia Dan (West Nghe An) was carried out. Rock-forming clinopyroxenes, the major trace element containers, were separated from to analyze for major, Sr-Nd isotopic compositions. The data interpreted source geodynamic processes lithospheric beneath region. being mostly spinel-lherzolites composition, are residual entities having been produced following partial melting events...

Cam Thuy Permian basalts consisting of thick lava flows and pyroclastic layers appear along both sides the Song Ma fault zone in Thanh Hoa Son La Ninh Binh provinces, NW Vietnam. The magmatism has been thought to have genetic relationship with volcanism Da rift zone, which is believed be part Emeishan large igneous province, having extruded Red River shear following Paleogene India-Eurasian collision. A set volcanic samples including olivine alkaline was collected Lam area (Tho Xuan,...

Policy research can reveal gaps and opportunities to enhance policy impact implementation. In this study, we use a theoretically informed qualitative approach investigate the implementation of two policies promote breastfeeding in Vietnam. We conducted semi-structured interviews with national local stakeholders (n = 26) 2017. Interviews were audio-recorded, transcribed verbatim then translated English by certified translators. Transcript data analysed using an integrated conceptual framework...

Nghia Dan Neogene basalts occur as monogenetic volcanoes and thin lava layers (up to tens of meters thick). They are alkaline basanites, some containing mantle xenoliths such spinel lherzolite. Compared with Tay Nguyen (Western Highlands) Cenozoic (for example, Pleiku DacNong) the show much lower SiO2 (45-48.5wt.%) higher FeO*(up 9-11 wt.%), TiO2 (2.5-3 wt.%) CaO (9-10 wt.%); they very high in trace element contents especially Ba, Th, Nb 130 ppm), Sr 2000 ppm) Eu 4 ppm). Their rare earth...

A set of samples including porphyritic rhyolite, rhyo-trachyte, trachyte and basalt was collected in the Tram Tau district, Tu Le Mesozoic Basin, NW Viet Nam for analysis major, trace, elemental Rb-Sr Sm-Nd isotopic compositions. The volcanic rocks are alkaline highly enriched trace elements rare earth (REEs). However, primitive mantle chondrite element normalized patterns expose strong negative anomalies Ba, Sr, Eu Ti, possibly reflecting fractional crystallization plagioclase (for Sr Eu),...

The adsorbent based electroplating sludge and rice husk char (CR) was prepared by ultrasonication method for adsorption of methylene blue (MB) Ciprofloxacin (CIP) in water. characteristics such as surface morphology, specific area, functional groups, element components confirmed SEM, BET, FT-IR, XRD EDX. results showed the is porous structure with BET area 175.22 m2/g, most pore width belonged meso section. Removal effectiveness MB CIP were 99.89% 74.96%, respectively after 90 min...

Mangrove forests have been globally recognized as they play a vital role in preventing coastal erosion, mitigating the effects of wave actions, and protecting habitats adjacent shoreline land-uses from extreme events. Sentinel-1 (SAR) offers new opportunity for mangrove cover mapping biomass estimation, especially tropics where deforestation degradation are highest cloud is persistent. This study used Sentinel-1A-derived VV/VH polarizations with thresholds -23.5<VH<-9.05...
