ISSN: 1365-3059Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Very severe infection of several crops of spring barley by Cochliobolus sativus occurred in Scotland during 1971–73. The most severely infected cultivar was Clermont, the high, susceptibility of which, combined with extensive seed infection, was responsible for the outbreak. Seed-borne infection by C. sativus was not wholly controlled by mercurial seed treatments, although no mercury tolerance was detected. The fungus is able to overwinter in the soil in Scotland and can also survive by infecting other graminaceous hosts. Several of these are believed to be new host records for this fungus in Britain.Type of Medium: Electronic ResourceURL: -

Published 1976Staff ViewISSN: 1365-3059Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The results of six studies using precision methods to obtain quantitative yield-loss relationships are reported. Losses ranged from 100 per cent for Pyrenophora graminea on barley, to 51 per cent in a simulated grazing trial on wheat, 20 and 8 per cent respectively for Fusarium nivale and Rhizoctonia solani causing culm lesions on wheat, and 12 per cent for yellow rust on barley. Evidence of interactions between seed treatment with mercury, F. nivale infection and mildew on barley is also presented, in which seed treatment was beneficial regardless of seed infection, and F. nivale intensified the loss due to mildew.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-0878Keywords: Photoreceptors ; Polychaete ; Submicrovillar cisternae ; Fine structureSource: Springer Online Journal Archives 1860-2000Topics: BiologyMedicineNotes: Summary The prostomium of Eulalia viridis has both microvillar and ciliary photoreceptors. The compound eyes each consist of a central lens surrounded by a layer of sensory and pigment cells. They resemble those of nereids, except that the lens is composed of vesiculated droplets produced by a specialized lenticular cell located in the cell layer surrounding the lens. Photoreceptoral microvilli of the sensory cell outer segments are underlain by “submicrovillar cisternae” (or SMC). The axial filament is ensheathed by part of the SMC complex. The sensory cells of the posterior photoreceptors are similar in cytology to those of the compound eyes but are not organized into “eyes”. Each ciliary photoreceptor unit consists of an extracellular vacuole bounded by a supporting cell and the ciliated terminal of a sensory cell dendrite which projects into the vacuole. They are similar to the ciliary photoreceptors of nereids. The discussion seeks to establish SMC as an important component of microvillar photoreceptors in polychaetes. SMC resemble subrhabdomeric cisternae of arthropod eyes and also lamellate structures found in photoreceptors of other animals. SMC are probably involved with the metabolism of photopigment.Type of Medium: Electronic ResourceURL: -

ISSN: 0362-2525Keywords: Life and Medical Sciences ; Cell & Developmental BiologySource: Wiley InterScience Backfile Collection 1832-2000Topics: BiologyMedicineNotes: The infracerebral gland of Nereis is made up of three types of cells. C1 cells are hypertrophied pericapsular elements, whereas C2 and C3 cells have the morphological and cytological features of neurosecretory neurons. C2 and C3 cells give rise to centripetal “proximal processes” which extend into the brain through the midventral pocket formed by delamination of the brain capsule. Their “distal processes” terminate within the gland or its immediate vicinity. “Centrifugal fibers” arise from nerve cells located within the brain and appear to synapse upon the proximal processes of C2 cells in the region of the midventral pocket and in the ventral region of the brain. The cytology of C2 and C3 cells suggests that they are the source of distinct peptide hormones.Type of Medium: Electronic ResourceURL: -

ISSN: 0362-2525Keywords: Life and Medical Sciences ; Cell & Developmental BiologySource: Wiley InterScience Backfile Collection 1832-2000Topics: BiologyMedicineNotes: The nuchal organs of polychaetes from four different families (Nereidae, Nephtyidae, Phyllodocidae and Glyceridae) were examined with the light and electron microscopes. In each case, the organ consists of ciliated cells and primary sensory elements. The ciliated cells are similar to the cells of the adjacent epidermis but bear motile cilia. Primary sensory neurons are situated within the organs in Nephtyidae and Phyllodocidae, but are located within the brain in Nereidae and Glyceridae. Each sensory cell gives rise to a distal process which penetrates between the ciliated cells to form an apical sensory bulb bearing modified cilia. Apically these processes are lined with juxtamembranous plaques. The ciliated cells are innervated by efferent axons from the brain, and in Nereis the axons appear to be peptidergic. The elements comprising the nuchal organs closely resemble those of the vertebrate olfactory mucosa.Type of Medium: Electronic ResourceURL: -

ISSN: 0363-9061Keywords: deformation analysis ; Shallow Strain Path Method (SSPM) ; penetration of clay ; Engineering ; Civil and Mechanical EngineeringSource: Wiley InterScience Backfile Collection 1832-2000Topics: Architecture, Civil Engineering, SurveyingGeosciencesNotes: A new method of analysis is described for estimating the deformations and strains caused by shallow undrained penetration of piles and caissons in clay. The formulation combines previous analyses for steady, deep penetration, with methods used to compute soil deformations due to near-surface ground loss, and is referred to as the Shallow Strain Path Method (SSPM). Complete analytical solutions for the velocity and strain rates are given for a planar wall, an axisymmetric, closed-ended pile and unplugged, open-ended pile geometries. In these examples, the analyses consider a single source penetrating through the soil at a constant rate, generating a family of penetrometers with rounded tips, referred to as simple wall, pile and tube geometries. Soil deformations and strains are obtained by integrating the velocity and strain rates along the particle paths.The transition from shallow to deep penetration is analysed in detail. Shallow penetration causes heave at the ground surface, while settlements occur only in a thin veneer of material adjacent to the shaft and in a bulb-shaped region around the tip. The size of this region increases with the embedment depth. Deformations inside an open-ended pile/caisson are affected significantly by details of the simple tube wall geometry. © 1997 by John Wiley & Sons, Ltd.Additional Material: 17 Ill.Type of Medium: Electronic Resource
