    THE DETERMINATION OF INTERIOR ORIENTATION ELEMENTS OF CLOSE RANGE CAMERAS WITHOUT CONTROL POINTS (1973)
    Oxford, UK : Blackwell Publishing Ltd
    The @photogrammetric record 7 (1973), S. 0 
    Details
    ISSN: 1477-9730
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Architecture, Civil Engineering, Surveying
    Notes: A novel method of calibration of non-topographic cameras is described, involving a simple three dimensional test object for photography at short object distances. The position of the camera with respect to the test object is resected at the same time as the computation of values of the interior orientation elements.

    Food habits of the mudskipper, Pseudapocryptes dentatus (Val.) (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 17 (1980), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The food habits of the mudskipper, Pseudapocryptes dentatus (Val.) ranging from 43 to 205 mm in total length collected from the mudflats at Fao estuary, Iraq were studied. A combination of numerical, frequency occurrence and gravimetric methods was used to analyse the stomach contents, both qualitatively and quantitatively. The fish was found to be a strict herbivore and a frequent feeder. It fed solely on phytoplankton dominated by benthic forms. Diatoms were the most important food item in respect of both numerical and frequency occurrence methods comprising about 84% of the total number of phytoplankton organisms. The types of phytoplankton that contributed significantly to the diet were, in decreasing order of importance, Pleurosigma, Navicula, Nitzschia, Synedra, Closteriopsis and Oscillatoria. Larger fish had consumed lesser amount of food, and there was usually a gradual decrease in consumption with increase in size. The mudskipper consumed food ranging from 1·3 to 10·5% of its body weight.

    The Amyloid Precursor Protein in Ischemic Brain Injury and Chronic Hypoperfusion (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Annals of the New York Academy of Sciences 695 (1993), S. 0 
    Details
    ISSN: 1749-6632
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Natural Sciences in General
    Notes: We studied changes in the spatial and temporal distribution of the β amyloid precursor protein (APP) of Alzheimer's disease (AD) in experimental ischemic brain injury. Rats with repeated reversible occlusions of one middle cerebral artery showed striking APP reactivity in astrocytic processes in perifocal regions and adjacent white matter. APP reactive dystrophic axons and neurons were also evident in the cortex and hippocampus ipsilateral to the MCA occlusion. Such changes were similarly apparent in animals subjected to partial forebrain ischemia induced by bilateral occlusion of the carotid arteries. Our studies suggest that focal ischemic insults or chronic hypoperfusion leads to increased accumulation or induction of APP in surviving cellular elements that may relate to the processes involved in β amyloid deposition in AD.

    The effect of Phragmidium mucronatum on rose understocks and maiden bush roses (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Plant pathology 32 (1983), S. 0 
    Details
    ISSN: 1365-3059
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Persistent infection of field-grown Rosa laxa hort, by the rust fungus Phragmidium mucronatum was observed throughout summer and autumn in 1979 and 1980. Rust significantly reduced shoot number, length and fresh weight (to 85 and 54% of the control after one and two seasons respectively) along with flower number and fruit yield. Root weight was also reduced to 55% of the control over two seasons.The growth of four bush rose cultivars budded on to rusted Laxa stocks was reduced, affecting bush quality. Overall, rust-free stocks produced twice as many saleable maidens as rusted stocks but bud take was not affected by P. mucronatum.

    Notes: The control of the rust fungus, Phragmidium mucronatum by seven fungicides (benodanil, fenpropimorph, oxycarboxin, thiram, triadimefon, triazbutyl and triforine), was examined both in vivo and in vitro. Oxycarboxin applied at monthly intervals to field-grown Rosa laxa gave excellent control. Similar results were obtained on detached leaflets using the fungicide as a protectant or eradicant. A benodanil-resistant isolate was identified in axenic culture.

    Induction of carbofuran oxidation to 4-hydroxycarbofuran by Pseudomonas sp. 50432 (2002)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 214 (2002), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Pseudomonas sp. 50432 biotransformed a highly toxic pesticide, carbofuran (2,3-dihydro-2,2-dimethylbenzofuran-7-yl methylcarbamate) to 7-phenol (2,3-dihydro-2,2-dimethyl-7-hydroxy benzofuran) and several unknown metabolites. One of the unknown metabolites identified by gas chromatography/mass spectroscopy was 4-hydroxycarbofuran (2,3-dihydro-2,2-dimethyl-4-hydroxybenzofuran-7-yl methylcarbamate). It had a mass (237) similar to 3-hydroxycarbofuran and 5-hydroxycarbofuran but different fragmentation patterns. This is the first report in which an inducible oxidative enzyme, hydroxylase, mediated the conversion of carbofuran to 4-hydroxycarbofuran. A second constitutively synthesized enzyme hyrolase transformed carbofuran to 7-phenol.

    Evidence on the presence of two distinct alkaline phosphatases in Serratia marcescens (2000)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 182 (2000), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Certain strains of Serratia marcescens synthesized two different types of alkaline phosphatase (APase), constitutive (CAPase) and inducible (IAPase) APases, in low phosphate medium. Synthesis of the IAPase was repressed in the presence of high phosphate. Purification and separation of these electrophoretically distinct APases was achieved by using fractional (NH4)2SO4 precipitation, adsorption on a DEAE-cellulose column and elution of enzymes by a linear sodium chloride gradient. Starch gel electrophoresis of certain fractions revealed the separation of not only IAPase from CAPase but its separation into four distinct isozymes. CAPase gave maximum enzyme activity around pH 9.5, whereas for IAPase a broad range of enzyme activity was found between pH 8.5 and 10.5. Reversible inactivation at low pH occurred for IAPase but very little with CAPase. CAPase was more thermolabile than IAPase at 95°C. The two APases were found to be distinct in their kinetic as well as immunological properties, suggesting two distinct enzyme species.

    Annual changes in the ovarian activity of the freshwater teleost, Barbus luteus (Heckel) from Southern Iraq (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 14 (1979), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The present paper describes the morphology, histology, and annual cyclical changes in the ovaries of Barbus luteus (Heckel). The ovaries are paired structures, joined by short oviducts. The ovarian structure consists of a number of lamellae, which contain the germ cells in various phases of maturation—immature, maturing and mature. Two types of yolk have been reported in the oocyte. The endocrine function of the gonads has been attributed to the follicular cells forming the ‘pre-ovulatory corpus luteum’ and ‘postovulatory corpus luteum’. The ovaries undergo a regular annual cycle which has been divided into five stages, based on various criteria, viz, ovarian size, colour, gonosomatic index, average ova-diameter, histological composition, and the spawning activity.

    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The testes of Barbus luteus are a pair of elongated structures composed of an anastomosing system of seminiferous lobules. Six spermatogenetic stages of germ cells have been described in the gonad. The endocrine factor lies in the interstitial cells. Spermiation occurs during the months of May, June and July. Fertilization appears to be external. Un-expelled spermatozoa undergo pycnotic degeneration. The testes show a regular annual cycle which has been described in five arbitrary stages.

    Salinity tolerance of Gambusia affinis (Baird & Girard) and Heteropneustes fossilis (Bloch) (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 11 (1977), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The present paper describes the results of a study on the salinity tolerance of two freshwater fishes, Gambusia affinis (Baird & Girard) and Heteropneustes fossilis (Bloch). The two species were treated with various concentrations of sea water and three most common salts found in the saline waters of Iraq, namely sodium chloride, calcium chloride and potassium chloride. The mortality rates following these treatments were recorded. Both species showed the highest degree of resistance for sea water and sodium chloride, and the lowest degree of tolerance to potassium chloride. Gambusia affinis was more resistant to these salts and sea water than H. fossilis.
