its gel structure in both the wet and dry states. Morpho- logical characterization by SEM indicates that the dried gel is composed of PVDF-HFP/graphene (0.25 wt% to PVDF-HFP) microspheres with a size distribution of 8~10 μm. The contact angles of pure PVDF-HFP and PVDF-HFP/graphene are 132.7 ± 2.7° and 151.6 ± 1.4°, respectively. This superhydrophobicity is due to the PVDF-HFP/graphene... Materials with appropriate surface roughness and low surface energy can form superhydrophobic surfaces, displaying water contact angles greater than 150°. Superhydrophobic carbon-based materials are particularly interesting due to their exceptional physicochemical properties. This review discusses the various techniques used to produce superhydrophobic carbon-based materials such as carbon fibers, carbon nanotubes, graphene, amorphous carbons, etc. Recent advances in emerging fields such as... -

turgor pressure due to increased intracellular glycerol. Proper sur- face signal sensing by the fungus stimulates the morpho- logical changes during the recognition phase. Thus, several signals are known to induce appressorium formation in M. oryzae. For example, an artificial hydrophobic surface is sufficient for appressorium formation (Lee and Dean, 1993). The spores of M. oryzae extend a... To establish an infection, fungal pathogens must recog- nize diverse signals from host surfaces. The rice blast fungus, Magnaporthe oryzae, is one of the best models studying host-pathogen interactions. This fungus recog- nizes physical or chemical signals from the host surfac- es and initiates the development of an infection struc- ture called appressorium. Here, we found that protein MoAfo1(appressorium formation, MGG_10422) was involved in sensing signal molecules such as cutin mono- mers and... -

the present study revealed wide morpho- logical variation among P. tritici-repentis isolates based on colony color and texture, mycelial radial growth, and conidial size prevalent on wheat in Algeria. Several researchers observed variation in mycelia color and colony morphology in P. tritici-repentis and its relat- ed species isolates collected from different geographical regions. Dos Santos... Tan spot caused by the fungus Pyrenophora triticirepentis is a serious disease of wheat, which is on increase in recent years in Mediterranean region. In the field this fungus produces a diamond-shaped necrotic lesions with a yellow halo on wheat foliage. The objective of this study was to characterize and compare several monospore isolates of P. tritici-repentis collected from different infected wheat fields in various locations of Algeria, and find the morphological differences between them,... -

the morpho- logical characteristics, particle sizes and surface area of the prepared catalyst was investi- gated. The prepared catalysts were characterized by several analytical methods: high resolu- tion scanning electron microscopy (HRSEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS). The XRD patterns... (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS). The XRD patterns showed that the supported TiO₂ nanocrystals are typically anatase, polycrystalline and body-centered tetragonal in structure. The EDS and XPS results complemented one another and confirmed the presence of carbon species in or on the TiO₂ layer, and the XPS data suggested the substitution of titanium in TiO₂ by carbon. Instead of using calcination, PAN pyrolysis was used... -

aortic hemodynamic, reactivity and morpho- logical changes. The rat’s weight throughout the 28-days experiment was deteriorating in nico tine-treated group although it was not significant. Previous study has shown a much higher nic- otine dose and longer period caused significant weight loss in rats given with nicotine at 2.5 mg/kg BW daily for 22 weeks [24]. The reduction in weight may be... Vascular remodelling is an adaptive mechanism, which counteracts pressure changes in blood circulation. Nicotine content in cigarette increases the risk of hypertension. The exact relationship between nicotine and vascular remodelling still remain unknown. Current study was aimed to determine the effect of clinically relevant dosage of nicotine (equivalent to light smoker) on aortic reactivity, oxidative stress markers and histomorphological changes. Twelve age-matched male Sprague-Dawley rats... -

by comparing its cultural and morpho- logical characteristics with descriptions published in the literature and by phylogenetic analysis (Rural Development Administration, National Institute of Agricultural Science and Technology, Plant Pathology Division, 2000). Zoospores probably function as the primary inoculum for infecting gom-chwi plants (Biles et al., 1995), however, a major problem is... Gom-chwi (Ligularia fischeri) is severely infected with Phytophthora drechsleri, the causal organism of Phy- tophthora root rot, an economically important crop disease that needs management throughout the cultiva- tion period. In the present study, Phytophthora root rot was controlled by using bacterial isolates from rhizo- sphere soils collected from various plants and screened for antagonistic activity against P. drechsleri. A total of 172 bacterial strains were isolated, of which, 49 strains... -

DNA from 75 F. graminearum strains, morphologically identified, was extracted using a CTAB method (Suarez et al., 2005), modified in this work using seven days fungal mycelium (100200 mg) and adding 1... Chemotype composition of Fusarium graminearum strains, isolated from durum wheat kernels from naturally FHB infected fields in Northern and Central Italy, was investigated by multiplex PCR. The different climatic and environmental conditions of the two examined areas separated by the Apennines affected the composition of chemotypes. 15Ac-DON chemotype was predominant in both the sub areas. Nivalneol chemotype was more frequent in the warmer sub area. -

Yield behavior of matrix precursor and interaction with reinforcement in randomly Con ict of Interest No potential confict of interest relevant to this article was reported.... The aim of the work was to investigate the thermo-electrical properties of low cost and rapidly produced randomly oriented carbon/carbon (C/C) composite. The composite body was fabricated by combining the high-pressure hot-pressing (HP) method with the lowpressure impregnation thermosetting carbonization (ITC) method. After the ITC method step selected samples were graphitized at 3000°C. Detailed characterization of the samples’ physical properties and thermal properties, including thermal...
