Residual resistance of impact-damaged reinforced concrete beams
Authors: Adhikary Satadru Das , Li Bing , Fujikake Kazunori
Published: December 2014

The behaviour of reinforced concrete (RC) beams under single or repetitive drop-weight impact loading has come under increasing attention within the engineering community in the past decades. However, until now, little effort has been sought towards examining the residual resistance of RC beams after impact damage. To contribute towards a better understanding in this area, both experimental and numerical investigations were carried out. The beams were first tested under drop-weight impact loading. Subsequently, quasi-static bending tests were conducted on the same specimens to obtain the residual behaviour. Thereafter, one beam from each series without any prior damage was tested under monotonic static loading to compare its behaviour with impact-damaged specimens. Furthermore, to investigate the structural response in detail, a numerical procedure was developed in an explicit finite-element program. Upon successful validation of the numerical results with the experimental outcomes, numerical case studies were carried out to quantify the variation of residual resistance index in terms of various parameters.
Evaluation of seismic slope-performance models using a regional case study
Authors: Miles Scott B. , Keefer David K.
Published: December 2014

This paper compares four permanent displacement models based on Newmark's sliding-block analogy for assessing regional seismic slope-performance. The models vary primarily by the ground motion descriptor used to correlate with Newmark displacement. The first uses peak ground-acceleration (PGA). The second uses PGA but normalizes displacements by predominant period and equivalent cycles. The third uses Arias intensity. The fourth calculates cumulative displacements from double-integrating simulated earthquake accelerograms. The models are implemented in a GIS to characterize seismic slope-performance for the Oakland East quadrangle near San Francisco, California. The resulting slope-performance maps are compared visually and through statistical analysis to expose potential differences and assess the effects of using a particular approach within a decision-making context. These maps were created for the purpose of comparison and are not suitable for use as critical decision-making tools. The models forecast notably different levels of slope-performance, with the PGA-based models predicting the greatest Newmark displacement on average. Thus, considering the variety of slope-performance models, it is suggested that practitioners avoid reliance on a single model. Instead, multiple models can be implemented in a GIS framework to gain a better perspective of the potential hazard and make a more informed decision.
Mine failure associated with a pressurized brine horizon; Retsof salt mine, western New York
Authors: Gowan Samuel W. , Trader Steven M.
Published: December 2014

The eventual loss of the Retsof Salt Mine from flooding was initiated on March 12, 1994 with a magnitude 3.6 earthquake, the collapse of a small-pillar panel, an initial inrush of brine and gas to the mine and a sustained inflow of fresh water. An examination of closure data for two mine panels involved in the inflow suggested an anomalous buildup of fluid pressure above the panels in the period leading up to their collapse. The initial brine and gas inflow immediately following the collapse coincided with the apparent relief of the excess pressure. The potential existence of a pre-collapse, pressurized, brine and gas pool above the panels was investigated through an analysis of nineteenth century solution mining data, a review of recent salt mine data, and an interpretation of geologic and geophysical data from post-collapse investigations. Published reports from the nineteenth century reveal that natural brine and gas pools existed in the region prior to mining. Correlation of gamma ray logs with geologic logs from contemporary drill holes and core holes provided a mechanism for interpreting the distribution of those natural brine pools. Our investigation indicated that natural gas and brine pools existed within Unit D of the Syracuse Formation approximately 160 ft above the mining horizon. Such brine accumulation apparently formed from the circulation of meteoric water through vertical discontinuities that were connected to overlying fresh water aquifers long before mining began in the valley in the late nineteenth century.
Subsidence risk in Venice and nearby areas, Italy, owing to offshore gas fields; a stochastic analysis
Authors: Cassiani Giorgio , Zoccatelli Claudio
Published: December 2014

Subsidence due to fluid withdrawal from the subsurface is being experienced in many regions. Water extraction for agricultural and civil needs is the most common cause of this phenomenon. However, hydrocarbon production from deep formations sometimes has been blamed for substantial rates of subsidence (e.g., Wilmington, California; Ekofisk, the North Sea). Hydrocarbon reservoirs in sensitive areas (lowlands), such as the Netherlands and the eastern Po River Plain in Italy, which includes the city of Venice, must be maintained under control to avoid actual or alleged subsidence. Because compaction in deep sediments is a relatively new research field, applicable data are sparse, and much work remains to be done. In particular, a strong discrepancy exists between rock compressibility values measured in the laboratory and in the field, these latter ones being probably more representative. Laboratory compressibility values are at least one order of magnitude larger than in situ values. Given this discrepancy, and in order to accommodate also for the variability of natural materials, a stochastic risk analysis is the most reliable tool for predicting subsidence due to hydrocarbon extraction. This approach is here applied to a planned gas production project from offshore fields in the northern Adriatic Sea, in order to assess the risk of subsidence on the coast and the nearby city of Venice. No stochastic theory of subsidence is available to date; consequently, a Monte Carlo technique is applied with respect to soil compressibility, which affects both the reservoir and subsidence simulations. A semi-analytical three-dimensional model based on the theory of Geertsma is used as a subsidence model. The results show that no actual risk of subsidence exists on the coast. Against intuition, the worst case scenarios coincide with the lowest compressibilities, since these values contribute to higher pressure declines in the reservoirs and the adjacent aquifers, and to a faster propagation of pressure change towards the shoreline. The results for the worst-case scenarios are confirmed by more sophisticated non linear, three-dimensional, finite element simulations.
Determination of optimum volume proportions for Sarooj (Pozzolan) lime mixes
Authors: Hago Abdel Wahid , Al-Rawas Amer , Al-Harthi Ali S.
Published: December 2014

Sarooj is an artificial pozzolan produced by burning special types of clays. It has been used extensively in Oman as a cementing material in concrete masonry construction, particularly in hydraulic structures, buildings and military installations. Sarooj is cementitious when mixed with lime and water. It is a cheap cementitious material for use in construction and restoration of historical buildings. An experimental research program was developed to determine the optimum volume proportions that can be used in concrete and mortar mixtures. Twenty five sarooj-lime mixes having different proportions of sarooj, lime, sand and water were tested. In addition, tow groups of mixes (sarooj, lime, sand, water) batched by weight and by volume, with each group contained three mixes of the same proportions, were tested to study the effect of the fineness of sarooj on the strength characteristics of the sarooj-lime mix. It was found that grinding sarooj to pass the 300 mu m sieve produced the highest compressive strength, while optimum volume proportions of sarooj, lime, sand and water for the highest compressive strength was 3:1:3:1.9.
Using an analytical geometry method to improve tiltmeter data presentation
Authors: Su Wen-June
Published: December 2014

The tiltmeter is a useful tool for geologic and geotechnical applications. To obtain full benefit from the tiltmeter, easy and accurate data presentations should be used. Unfortunately, the most commonly used method for tilt data reduction now may yield inaccurate and low-resolution results. This article describes a simple, accurate, and high-resolution approach developed at the Illinois State Geological Survey for data reduction and presentation. The orientation of tiltplates is determined first by using a trigonometric relationship, followed by a matrix transformation, to obtain the true amount of rotation change of the tiltplate at any given time. The mathematical derivations used for the determination and transformation are then coded into an integrated PC application by adapting the capabilities of commercial spreadsheet, database, and graphics software. Examples of data presentation from tiltmeter applications in studies of landfill covers, characterizations of mine subsidence, and investigations of slope stability are also discussed.
Coastal flooding and beach retreat from coseismic subsidence in the central Cascadia margin, USA
Authors: Peterson Curt D. , Doyle Debra L. , Barnett Elson T.
Published: December 2014

Prehistoric great earthquakes (Mw 8-9) in the central Cascadia margin have produced coastal subsidence (0-2 m) that has resulted in chronic lowland flooding and catastrophic beach erosion. Geologic records of wetland burial in 13 bays from Washington and Oregon are used with simple calculations to estimate likely coastal flooding and beach retreat following a great Cascadia earthquake. Plant macrofossils and peat-to-mud ratios recorded in core logs discriminate between forest, marsh, colonizing marsh, and mud-flat tidal settings. Transitions between these settings, i.e., across abrupt burial contacts, demonstrate either 0+ or -0.5, 1+ or -0.5, or 2+ or -0.5 m of paleosubsidence. Paleosubsidence from the last Cascadia event (AD 1700) decreases from 2+ or -0.5 m in the eastern reaches of south-west Washington bays to 0+ or -0.5 m in the western reaches of central Oregon bays. First-order estimates of post-subsidence flooding hazards are based on the predicted regional subsidence added to current 10- and 100-year flood elevations. At least 525 km of bay shorelines are threatened by chronic flooding following coseismic subsidence. Catastrophic beach retreat is estimated from Bruun's Rule to range from 50 to 300 m depending on assumed depth of closure, measured beach-berm heights, and predicted coseismic subsidence along the margin. Shorelines that are susceptible to catastrophic beach retreat from coseismic subsidence total at least 250 km in longshore distance.
Ultrashallow seismic reflection monitoring of seasonal fluctuations in the water table
Authors: Baker G. S. , Steeples D. W. , Schmeissner C. , Spikes K. T.
Published: December 2014

Ultrashallow seismic-reflection data were collected at a test site in Great Bend, Kansas. The purpose of the experiment was to image seasonal submeter-scale fluctuations in the water table over a period of one year to identify the factors important in monitoring the water table when using seismic-reflection techniques. The study indicates that detailed velocity information must be used when interpreting water-table levels. Using detailed velocity information as a control when depth-converting the seismic profiles yielded correct positioning of the water table within + or -12 cm at the test site.
Hydraulic conductivity of the Portland Basin deep aquifer system
Authors: Koreny John S. , Fisk Terry T.
Published: December 2014

The Portland Basin is 900 mi 2 in size and includes portions of Oregon and Washington. A deep aquifer system of the Troutdale Formation is used for municipal ground-water supply in both states over an area of approximately 300 mi 2 . Although lateral sedimentary facies variations are evident in the lithologic record, data from multi-well aquifer tests show that the aquifer forms a continuous hydrostratigraphic unit in both states. The aquifer is synclinal and in the center of the basin is well-confined by low-permeability layers. On the eastern and western margins of the basin, the aquifer is in hydraulic continuity with a buried Columbia River paleo-channel. The paleochannel forms a boundary to the aquifer and relative head differences between the aquifer and the river cause ground water to flow up the formation dip and against the Columbia River gradient in the eastern portion of the basin. The paleochannel acts as a discharge sink during low-pumping periods and a recharge source during extended pumping. Municipal use of ground water in the deep aquifers includes: a) continuous use which has increased from approximately 1 to 2 mgd in 1984 to 13 mgd in 1998 and, b) emergency use which has caused total use peaks of 55 mgd. The increased ground-water use has resulted in a modified flow regime causing the aquifer to receive induced recharge through the paleochannel deposits. The induced recharge available from the Columbia River may allow for further efficient development of groundwater supplies on the eastern and western margins of the basin.
Investigation of three methods for evaluating swelling pressure of soils
Authors: Attom Mousa F. , Barakat Samer
Published: December 2014

Determination of the swelling pressure of six types of clayey soils obtained from northern Jordan were measured using three methods, the Free Swell method, Different Pressure method, and the Zero Swell method. These methods show different values in swelling pressure of the soil. For all six soils, the Free Swell method provided the highest value, whereas the Different Pressure method provided the lowest. Discrepancy in the value of swelling pressure among the methods increases with lower initial water content, higher plasticity index, and clay content. This paper compares the three different methods for evaluating soil swelling pressure and presents mathematical models to predict the soil swelling pressure for each method.
The effects of water on planar features in compound slopes
Authors: Kroeger E. Bane
Published: December 2014

Plane failure in rock and soil slopes is usually caused by the intersection of a discontinuity plane with a slope face. Typically, discontinuities are weaker than the surrounding intact material and provide a surface along which movement can occur. When designing a stable slope, it is often desirable to find the most critical conditions for a particular slope configuration and base the final slope design around those conditions. The worst case for most dry slopes usually includes a tension crack at a location determined by the slope geometry. The worst case for saturated slopes typically has a tension crack at the slope crest, providing the deepest tension crack, and a fully or partially dammed discontinuity. This paper focuses on plane failure analyses of compound slopes using limit equilibrium techniques. It provides new equations to calculate the position of a tension crack, water forces, and stability factor in compound slopes. The results of a compound slope and water pressures are illustrated through several examples.
Site-specific variation in the potentiometric response to subsidence above active longwall mining
Authors: Booth Colin J. , Curtiss Alan M. , Demaris Philip J. , Bauer Robert A.
Published: December 2014

Longwall underground coal mining produces major changes in the hydraulic properties and groundwater levels of overlying shallow aquifers because of the fracturing associated with mine subsidence. Many aspects of these impacts remain unclear and unpredictable, particularly the variations in response between different sites. Our detailed, long-term studies of subsidence strains and hydraulic responses at sites in Illinois address this and other aspects of the conceptual model. At a study site in Saline County, inconsistent permeability changes and large rapid head drops, without significant recovery, were observed in a low transmissivity sandstone over an active longwall panel. Corresponding head changes in overlying glacial drift units reflected localized drainage from the drift to the bedrock. In comparison to our earlier study at a site in Jefferson County, Illinois, in which full recovery occurred in a moderately transmissive sandstone aquifer affected by longwall mining, the Saline site illustrates the importance of local hydrogeologic characteristics, particularly variations in transmisivity and continuity with recharge sources, in controlling site-specific responses to longwall mining.
Calculating equivalent radial distances for determination of transmissivity and storativity using drawdown data from a multiple pumping well systems
Authors: Orient Jeffrey P.
Published: December 2014

A method is presented for the determination of aquifer transmissivity (T) and storativity (S), using distance-drawdown data from a wellfield with multiple pumping and observation wells. An equivalent radial distance calculated for each observation well, the aggregate system pumping rate (Q), and drawdown data for two or more nearby observation wells are used in the calculation of T and S. The method described can be used to evaluate complex pumping systems, as it can accommodate multiple pumping wells discharging at the same or at different rates, and varying well spacings. It can also accommodate a combination of both pumping and recharge wells concurrently operating. This versatile approach is particularly useful in determining the aquifer transmissivity and storativity for a series of extraction wells installed to remediate ground water, for use in subsequent capture zone and other design/performance evaluations. It is also useful for determining aquifer characteristics for evaluation of an operating water supply wellfield.
Evaluation of alternative cover systems using GIS
Authors: Coonrod Julie , Stormont John , Vantassell Lisa
Published: December 2014

Geographic Information Systems (GIS) can be used to determine and display the depths of native soil covers required for waste containment sites. Readily available data for the State of New Mexico are used in a GIS environment to determine the required depth of two separate cover systems. The depth of an evapotranspirative (ET) soil cover is determined using the available water capacity of the soil and the amount of dormant precipitation. The thickness of a capillary barrier cover system is determined using unsaturated hydraulic parameters, the amount of dormant precipitation, and an iterative numerical model. A difference map showing the savings using a capillary barrier instead of an ET cover is then created. The use of a capillary barrier in areas with fine-grained soils can decrease the necessary soil cover thickness by 90 cm of soil. The computed cover thickness compare well with those determined using Hydrologic Evaluation of Landfill Performance (HELP) (Schroeder et al., 1994), a model commonly used in New Mexico to determine if alternative cover systems can meet the required performance criteria.
Effects of anisotropic transmissivity on a contaminant plume at Nemo, South Dakota
Authors: Rahn Perry H. , Johnson Christopher S.
Published: December 2014

In 1996 low concentrations of ethylene dibromide (EDB) were found in thirteen domestic water wells in Precambrian metamorphic rocks at Nemo, South Dakota. The source of the contaminant is believed to be the result of pesticides disposed at a U.S. Forest Service Work Station area in the 1970s. Monitoring wells were installed and ground water from nine of them contained EDB. Sixteen additional wells within three kilometers of Nemo were sampled but EDB was not detected. Water in two domestic wells one kilometer south-southeast of Nemo had high concentrations, 13 and 2.2 micrograms per liter of EDB. The impacted landowners were initially provided bottled water by the USFS. The USFS then drilled new wells outside of the contaminant plume which now provide water to the impacted landowners. An equipotential map indicates that ground water should flow easterly. However the contaminant plume extends towards the south-southeast, in the direction as the foliation in the Precambrian phyllite and quartzite at Nemo. This foliation strongly influences the direction of contaminant migration. Based on an equipotential map and the known plume orientation, a graphical solution of the transmissivity anisotropy indicates that the major transmissivity is oriented N 10 degrees W and is approximately 0.73 m 2 /d. The minor transmissivity is 0.13 m 2 /d. A computer solution utilizing anisotropic transmissivity generated a plume which agrees with the field data.
Characteristics of deep-seated landslides of Hokkaido; analyses of a database of landslides of Hokkaido, Japan
Authors: Yamagishi Hiromitsu , Ito Yoji , Kawamura Makoto
Published: December 2014

More than 12,800 deep-seated landslides of Hokkaido were inventoried by photointerpretation, and plotted in topographic maps (Yamagishi,1993). They were later published in a database of land-slides (Yamagishi et al.,1997), which is composed of localities (latitude and longitude), scales (length, width and area), elevation, directions, and geologic lithofacies of the main scarp and underlying bedrock. Several parameters of the landslides from the database, such as frequency histograms, scale, elevation, direction and lithofacies were analyzed. As a result, landslide distribution maps from many points of view were obtained, as well as many graphs by numerical analyses.
A combined GIS and HEC model for the analysis of the effect of urbanization on flooding; the Swan Creek watershed, Ohio
Authors: Wiles Jason J. , Levine Norman S.
Published: December 2014

This study investigates the effects of changes in land-use on the hydrology of the Swan Creek watershed in Lucas County, Ohio, over a thirty-year period. The study presents the GIS based runoff models and the HEC-RAS Flood analysis for the watershed. The runoff modeling was performed using a modification of the rational formula first proposed by Rossmiller in 1980. The C factor (land use) in the rational equation (Q = CIA) is modified to account for land use, soil type and slope factors. Four model runs for each of the land-use coverages were created based on the statistical precipitation recurrence intervals: P 10 , P 25 , P 50 , P 100 (a total of 12 model runs). The models differed only in the basic land-use classifications for each decade of interest. The runoff analysis predicts that increased runoff volumes in the watershed are directly related to increasing urbanization. The study showed that runoff volumes of a P 100 storm in 1973 of certain sub-basins has the equivalent runoff of a P 10 storm in 1995. The flood modeling was performed in the Army Corps of Engineer's Hydrologic Engineering Center's River Analysis System (HEC-RAS). Twelve model runs were also created in HEC-RAS to evaluate the effect of the land-use changes in each of the time periods for each of the storms. The study showed that flood extent of a P 50 storm in 1973 across the watershed has the equivalent flood extent of a P 10 storm in 1995. The flood modeling predicts that the Swan Creek hydrologic system responds more quickly and severely today to events that would have been smaller in the past.
Observations on brucite formation and the role of brucite in Iowa highway concrete deterioration
Authors: Lee Hyomin , Cody Robert D. , Cody Anita M. , Spry Paul G.
Published: December 2014

Iowa highway concretes containing reactive dolomite, (CaMg) 2 CO 3 , aggregate, composed of fine-grained, microporous dolomite, sometimes have service lives of less than 10 years. This premature deterioration may, in part, be caused by expansive forces created by newly formed minerals such as brucite, Mg (OH) 2 , in the cement paste as a result of dedolomitization of reactive dolomite coarse aggregate. Although calcite is the most abundant secondary mineral in cements of poorly-performing concretes, the present study found no evidence that it was expansionary. Brucite is common but less abundant than calcite and occurred chiefly in and near the margins of reactive dolomite in both the aggregate and cement paste of poorly-performing concretes. Most brucite occurs in partially dedolomitized rims around dolomite coarse aggregates. This type of brucite is widely disseminated through the rims, consists of extremely small (<1 m) microcrystalline masses, and was produced by direct precipitation from pore solutions. Smaller amounts of brucite occur in the cement paste. This type is relatively coarse-grained (10 mu m-20 mu m) and most was formed primarily by crystal surface mediated (topochemical) reactions between magnesium-rich pore solutions and portlandite, Ca(OH) 2 . Numerous microcracks are present in cement paste but are not spatially associated with brucite locations. There is no direct evidence for cracking caused by brucite but this is not conclusive evidence against brucite-induced expansion. Brucite is widely disseminated so that expansion at innumerable micro-locations may cause general concrete expansion which should be relieved by cracking at weaker locations in the concretes.
A laboratory investigation of some factors affecting the stability of a mine in the Eastern Transvaal coalfield, South Africa
Authors: Bell Fred G. , Jermy Colin A.
Published: December 2014

The stability of roofs and floors in pillared coal mines is affected by a number of properties of the strata above and below the coal seam which is worked. These include the lithological character of the rocks, the sedimentary features contained within them, the geomechanical properties of the rocks, notably their strength and deformation moduli, the durability of the rocks on exposure, and the incidence and geometry of discontinuities. Instability also can be associated with the development of excessive methane and water pressures in the strata surrounding a worked coal seam. Accordingly, rock-core material was obtained from a mine in the Eastern Transvaal Coalfield in order to investigate the influence of certain of these properties on the stability of the roof and floor of the mine. The investigation showed the existence of a number of sedimentary facies that had different geological characteristics and geomechanical properties. A large number of compressive and tensile strength tests were carried out on the rock-core material, as was permeability testing. The latter was undertaken using an Ohle cell, a Bernaix cell and a Hoek triaxial cell. The permeating fluids were nitrogen, methane and water, except in the case of the Hoek cell in which only methane was used. The Hoek cell allowed permeability to be determined under different stress conditions. In addition, the geodurability of the rocks of the argillaceous facies also was determined. The compressive and tensile strength of the various facies varied notably and the latter frequently showed significant anisotropy. Permeability tended to increase with increasing grain size in the coarser-grained facies whereas the opposite tended to occur in the fine-grained facies when tested with gas. The application of stress brought about a decrease in permeability. In the Bernaix cell, divergent flow was greater than convergent flow. The tensile stress that developed during divergent flow testing with water caused some specimens to fail. The durability indicated that some of the argillaceous material was of very poor quality.

La dissolution des carbonates en milieu oceanique; son role dans la genese des depots pelagiques pendant le Cenozoique
Authors: Leclaire L. , Clocchiatti M.
Published: December 2014

A review of previous works complemented with new data from the Indian Ocean at all latitudes indicates that the CCD is variable in the three main oceans following latitudes and basins. Despite the fact that the CCD is not directly related to the carbonate equilibrium in sea water, it seems probable that the degree of undersaturation of deep waters acts on the rate of dissolution of calcium carbonate contained in the sediments. Finally, the CCD would depend on the rate of dissolution and also on the rate of sedimentation. The CCD which delineates also the red clays-calcareous oozes boundary is presently controlled by surface water productivity (biochemical calcium carbonate precipitation rate), by interoceanic mixings of deep bottom waters and by river discharges. During the Quaternary, changes in the CCD are thought to be controlled by climatic fluctuations from which depend the rate of the calcareous biochemical precipitation and the river runoff. Correlations developed in this paper show that the Cenozoic climatic fluctuations (especially the Neogene and Quaternary ones) would have caused fast and high CCD fluctuations. (Auth. mod.)
Contribution a l'etude du volcanisme de l'arc des Nouvelles-Hebrides; caracterisation de deux series magmatiques de l'ile d'Erromango
Authors: Marcelot G. , Lefevre C. , Maillet P. , Maury R. C.
Published: December 2014

The volcanic series of Mt Rantop and Robertson's Thumb, Erromango Island, New Hebrides, formed by fractional crystallization of orogenic basaltic magma of near-island-arc tholeiitic type. Differentiation was controlled mainly by separation of plagioclase, olivine and clinopyroxene. The Mt Rantop series is predominantly tholeiitic (plagioclase at the liquidus, late appearance of magnetite, pigeonite in microphenocrysts, and Fe and Ti remaining constant or increasing in the early stages of differentiation); those of Robertson's Thumb are mostly calc-alkaline (magnetite at the liquidus, late appearance of plagioclase, olivine quickly becoming unstable, orthopyroxene in phenocrysts and early decrease of Fe and Ti). The compositional differences reflect higher fO 2 and PH 2 O in Robertson's Thumb during fractional crystallization.
Mise en place et evolution magmatique des complexes plutoniques de la caldera de Courbet, ile Kerguelen (T.A.A.F.)
Authors: Giret A. , Lameyre J.
Published: December 2014

The two plutonic intrusions of the caldera of the Courbet Peninsula in Kerguelen Island present different styles of emplacement and trends of differentiation. In the Montagnes Vertes intrusion, which illustrates a cauldron subsidence process of emplacement, the petrographic evolution is centripetal; it evolves gradually from outer basic rocks to differentiated rocks in the core, following an alkaline and weakly silica undersaturated trend. In the Mamelles intrusion, which shows good evidence of diapirism, the differentiates are silica-saturated or oversaturated and overlay the basic rocks. Such evolution is consistent with amphibole fractionation and this process suggests an intense water/magma interaction. (Auth.)
Dechirures continentales et plutonisme; Etude petrologique et structurale comparee de l'association ignee de Guevgueli (Macedoine grecque) et des formations plutoniques basiques situees en bordure nord du Massif des Ballons (Vosges, France)
Authors: Andre Francis , Bebien Jean
Published: December 2014

The Guevgueli igneous association and the Ballons massif are intrusive into a rhyolitic volcaniclastic series. They both contain gabbro-dioritic cumulates and abundant magmatic breccias containing melanocratic microgranular and leucocratic granular rocks. Two distinct parageneses, formed under different PH 2 O, one with bytownite, the other with amphibole + or - biotite + or - ferro-titanian oxides, control the magmatic differentiation processes. Structural studies reveal diastrophisms which favoured a water contribution from the sialic country rocks during magmatic crystallization. An emplacement in continental fractures accounts for the distinctive features of these rocks.
Effects of biological insecticides NeemAzal T/S and pyrethrum FS EC and their interaction with organic products in treatments of pea aphid Acyrthosiphon pisum (Harris) (Hemiptera: Aphididae) on Pisum sativum (L.)
Authors: Nikolova Ivelina , Georgieva Natalia
Published: December 2014

The efficacy and effects of two biological insecticides, NeemAzal T/S? and
Pyrethrum FS EC, applied individually and in combination with Polyversum (a
biological growth regulator and fungicide) and Biofa (an organic foliar
fertilizer), in controlling Acyrthosyphon pisum population density were
studied. Nurelle D (a synthetic insecticide), applied alone and in
combination with Flordimex 420 (a synthetic growth regulator), was used as a
standard. The products were applied once (at budding stage) or twice (at
budding and flowering stages). Twenty-four variants were studied. The
interaction of Pyrethrum with Biofa was the most efficient variant of the
biological products, causing a reduction in aphid density that reached 48.2%
after double treatment, while Pyrethrum+Polyversum (42.5%) was the second
most successful treatment. The combination of Pyrethrum with Biofa achieved
the highest efficacy and synergism and their efficacy approached that of the
synthetic insecticide.
