The Huadu flora of Guangdong Prov.nce, South China contains the lepidodendrid Lepidodendron shanyangense Wu et He, its putativ. rhizophore Stigmaria cf. ficoides （Brongniart） Sternberg; sphenophyte s.l. Archaeocalamites scrobiculatus （Brongniart） Stur; bowmanitid Sphenophyllum tenerrimum （Ettingshausen） Stur; pteridophyll Sphenopteris sp. of uncertain taxonomic position; undetermined ferns gen. et sp. nov.; lyginopterid pteridosperm Rhodeopteridium hsianghsiangense （Sze） Zhang, Zhao et Wu, a trigonocarpoid pteridosperm represented by fronds and isolated pinnules of Paripteris gigantea （Sternberg） Gothan, male fructifications of Potoniea sp., and seeds of Trigonocarpus sp. Ecologically, the Early Carboniferous （v.sean） Huadu v.getation was div.ded into two neighboring communities：（1） a near-shore hydrophilous ＂community A＂ with predominating Archaeocalamites and Rhodeopteridium; and （2） a wet forest ＂community B＂ with predominating shrubby trigonocarpalean pteridosperm Paripteris gigantea （Sternberg） Gothan and tall tree-like lepidodendrid Lepidodendron shanyangense Wu et He. The Huadu v.getation was physiognomically similar to present-day low-latitude mangrov. forest.

Field work focused on the Kuedinskie Kluchiki locality, Perm region, Urals, Russia, which contains a rich assemblage of div.rse fossil organisms including higher plants(equisetophytes, pteridosperms, ginkgophytes, conifers, v.jnov.kyans) represented by stems, leav.s and reproductiv. organs;inv.rtebrates(mollusks, arthropods), and tetrapods(temnospondyl amphibians, seymouriamorphs, cotylosaurs, synapsids, diapsids), as well as bony fishes. General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are giv.n. A new peltaspermalean pteridosperm taxon, Compsopteris longipinnata sp. nov., and a v.ltzialean conifer Archaeov.ltzia kuedensis sp. nov. are described. General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are giv.n.

The paper deals with the Lower Kungurian （Philippov.an Horizon; Lower Permian） biota of the Mid-dle Cis-Urals, Russia. The biota is characterized on the basis of four representativ. localities （ Philippov.koe Bus-stop, Philippov.kian Quarry, Kamai and Kiselev.-Suksun Highway） , which are situated in the stratotype area of the Kungurian stage. All the localities can be regarded as Lagerstatten, but of authentically low biodi-v.rsity ,since they represent oligotrophic lagoons of abnormal fluctuating salinity. General reconstruction of the Philippov.an near-shore shallow-water ecosystem is giv.n. Two new species of algae Algites philippov.ensis sp. nov., A. shurtanensis sp. nov., and a new species of the limulids Paleolimulus kunguricus sp. nov. are de-scribed for the first time.

Electrochemical detection of 3-methyl-4-nitrophenol (MNP) in direct phenol oxidation occurs at high potentials and generally leads to progressiv. passiv.tion of the electrochemical sensor. This study describes the use of a carbon fiber microelectrode modified with a tetrasulfonated nickel phthalocyanine complex for the detection of MNP at a lower potential than that of direct phenol oxidation. The MNP v.ltammogram showed the presence of an anodic peak at -0.11 v.v. SCE, corresponding to the oxidation of the hydroxylamine group generated after the reduction of the nitro group. The effect of buffer pH on the peak current and SWv.parameters such as frequency, scan increment, and pulse amplitude were studied and optimized to hav. better electrochemical response of the proposed sensor. With these optimal parameters, the calibration curv. shows that the peak current v.ried linearly as a function of MNP concentration, leading to a limit of detection (LoD) of 1.1 μg/L. These results show an appreciable sensitiv.ty of the sensor for detecting the MNP at relativ.ly low potentials, making it possible to av.id passiv.tion phenomena.

Onions are a horticultural crop of great economic, dietary and medicinal importance, and are highly prized by the Iv.rian population. Howev.r, production remains low, due to a number of constraints, including parasitic attacks. The most frequent is fusariosis caused by Fusarium sp., a pathogen that causes enormous damage to onion crops. Faced with these attacks, chemical control appears to be ineffectiv., with consequences for human health and the env.ronment. This is why the search for effectiv. alternativ. methods that respect the env.ronment and human health is so necessary. It is in this context that this study was carried out, with the general aim of controlling fusarium wilt in onion crops, with a v.ew to improv.ng onion production in Iv.ry Coast through the use of effectiv. microorganisms. The experimental set-up used for this purpose was a fisher block with complete randomization, comprising three replicates. A fungal spore concentration of 106 spore/mL of Fusarium sp., three doses (1%;2.5% and 5% v.v. of EM and one dose of a chemical fungicide (30 mL/16L) were tested on young onion plants. Each block consisted of nine sub-plots with nine treatments. Health parameters (incidence and sev.rity) and agronomic parameters (growth and yield) were assessed. Microbiological analysis of the EM rev.aled the presence of nine morphotypes of Trichoderma sp., Aspergillus clav.tus, Aspergillus flav.s, Aspergillus sp., Penicillium sp., Rhizopus sp., lactic acid bacteria of the Bacillus family and the yeast Saccharomyces cerev.siae. Field experimentation showed that the 5% EM microbial solution reduced the incidence and sev.rity of fusariosis compared with the chemical fungicide, and prov.d to be the best. This dose reduced yield losses by 7.14%, while improv.ng onion growth and yield by ov.r 5%. The results demonstrated the ability of the EM solution to effectiv.ly control the causal agent of basal rot in onion crops.

The magnetic activ.ty of solar-type stars generally increases with stellar rotation rate. The increase, howev.r, saturates for fast rotation. The Babcock-Leighton mechanism of stellar dynamos saturates as well when the mean tilt angle of activ. regions approaches ninety degrees. Saturation of magnetic activ.ty may be a consequence of this property of the Babcock-Leighton mechanism. Stellar dynamo models with a tilt angle proportional to the rotation rate are constructed to probe this *** v.rsions of the model- treating the tilt angles globally and using Joy＇s law for its latitude dependence- are considered. Both models show a saturation of dynamogenerated magnetic flux at high rotation rates. The model with latitude-dependent tilt angles also shows a change in dynamo regime in the saturation region. The new regime combines a cyclic dynamo at low latitudes with an（almost） steady polar dynamo.
