    Notes: Experiments are described which test the feasibility of diminishing the leachate production of sanitary landfills by using the roots of transpiring plants to dry the refuse and surrounding soil. Full-scale models of landfill cores were constructed and filled with typical municipal refuse in the early spring of 1973. Selected plant species such as slash pine, thorny elaeagnus, bristly locust, black locust, and two grasses were used to vegetate two landfill models, while a third was denied vegetation and used as a control. Intermediate term results have been positive from several viewpoints. The various species of selected plants have thrived, even though gas sampling indicated that the lower two-thirds of the landfill models quickly became anaerobic. Roots proliferated rapidly through the top 2 1/2 feet (76.2 cm.) of cover soil and first refuse layer. Following December 1973, all three lysimeters began producing leachate. However, the volume of leachate produced differed considerably depending on whether the particular lysimeter was vegetated or fallow. To date, the unvegetated control has produced 17.53 inches (44.53 cm.) while the two vegetated models have produced 8.59 inches (21.82 cm.) and 2.49 inches (6.32 cm.) respectively. The lysimeter producing the minimum leachate volume was vegetated with pine and thorny elaeagnus. The unvegetated bin produced the most dilute leachate. If one uses the chemical oxygen demand, the total Kjeldahl nitrogen, and the total solids as indices representative of the potency of leachate, then the leachate from the lysimeter containing pine and thorny elaeagnus was 1.97 times more concentrated than that from the fallow lysimeter. Thus one realizes a net improvement factor of 3.57 due to the presence of plants.

    Notes: This paper presents the main trends in epigenetic research in the U.S.S.R. in the last years:〈list xml:id="l1" style="custom"〉1Study of epigenetic zonality in thick series of sedimentary rocks of various ages and tectonic regions, (zones of unaltered clay matrix, of altered clay matrix, of quartzitic structures and hydromica-chloritic cement, and of prick-like structures and phyllite-like schists).2Principles of stadial analysis and mineral indicators of different epigenetic stages (clay minerals, organic matter, zeolites, feldspars, sulfides).3Facies of regional epigenesis connecting the main petrographic families of unaltered terrigenic rocks (quartz sandstones with kaolinitic matrix and the same composition of associated clays, acidic arkoses with hydromicaceous clays, lithoclastic sands with several matrix components and associated clays, and volcanogenic greywackes) with “related” facies of regional metamorphism.4Some practical aspects of epigenesis are: for petroleum geology: maximum depth of burial according to porosity, interruption of quartz, feldspar, sphene, epidote, carbonate, biotite, and clay mineral epigenesis by oil migration; and for ore geology: (a) initial epigenesis: ore impregnation (e.g., volkonskoite in wood remains) due to intrastratal solution of heavy minerals and leaching of rock fragments; (b) deep epigenesis: e.g., galena impregnations due to release of trace elements during dissolution of rock forming minerals e.g., feldspars; and (c) metagenesis: “Alpine” veins across and along bedding, filled, e.g., with copper ores.

    GENETIC INTERPRETATION OF THE POLYMORPHISM OF THE KAOLINITE GROUP IN SEDIMENTARY ROCKS (1970)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The paper presents the dynamics of the structural change of kaolinite and its polymorphous (polytype) modifications at different stages of sedimentary rock formation. Sedimentogenesis is characterized by a gradual disordering of structure of triclinic kaolinite, the degree of disorder produced being proportional to the intensity and duration of the influence of the hydrodynamic medium. Epigenesis (deep) is connected with gradual transformation of kaolinite into dickite through the stage of mixed-layer growths inheriting the structure of twin rotations of disordered kaolinite from the sedimentogenesis stage.In metagenesis filling of fissures with dickite or nacrite takes place. The former is peculiar to the general thermodynamic medium of deep epigenesis/metagen-esis, whereas nacrite is an indicator of intense stress and seems to be due to transformation of dickite.

    NEW ASPECTS OF THE OPTICAL STUDY OF LAYER SILICATES (1970)
    Oxford, UK : Blackwell Publishing Ltd

    Topics: Geosciences
    Notes: The structure of multilayer polytype modifications of layer silicates may be regarded as the result of a combination of regularly oriented single layers. Accordingly, the optical constants of a single layer (of a monolayer polytype modification) may be used for the calculation of optical constants of any other multilayer polytype modification of a given type of layers.The formulas connecting the constants of a polytype modification of layer silicates have enabled the establishment of the main parameters (Ng, Nm, Np, 2V) of the muscovites 1M and 2M2 according to the known optical constants of the muscovite 2M1, and the computation of the new constants of kaolinite and nacrite based on the known parameters of dickite. The optical constants established theoretically were confirmed by direct measurements for muscovite 1M, muscovite 2M2 (gämbelite) and kaolinite. The optically positive character of kaolinite with +2V = 25° has been established.The assumption of the optical mixibility of finely dispersed polyminerallic media, in which the dimensions of monotype crystals are smaller than the visible light waves, made it possible to determine the quantitative relations of clay minerals in the mixtures based on optical constants of oriented aggregates.

    DIETARY EFFECTS ON BEEF COMPOSITION. 4. Processing and Palatability Attributes (1971)

    Notes: SUMMARY– The influence of dietary regimen of 104 half-sib Angus steers allotted to 1 of 13 combinations of hay, corn silage and corn concentrate, and of slaughter weights of 284 vs. 340 kg and 409 vs. 454 kg (live weight) on processing qualities and palatability of beef was studied. Measurements included postmortem glycolytic activity, water- and fat-binding capacity, textural properties, cooking losses, flavor and juiciness of selected muscles. Results showed that feeding regimens had a greater effect than did slaughter weight on qualities studied. Corn silage in the early dietary regimen of cattle weighing 284 and 340 kg resulted in significantly lower pH values (5 and 45 min post-mortem), higher amounts of glycogen at slaughter and greater water- and fat-binding capacity as compared to hay. Similar effects of early diet were noted for 5- and 45-min pH and water-binding capacity in cattle fed to heavier weights (409 and 454 kg); however, in these animals the early-hay diet resulted in greater muscle glycogen deposition than the early-silage diet. Steaks from animals fed corn silage in the early period were determined to be more tender by both shear values and panel scores and were more juicy and flavorful than those from hay-fed animals. These differences in palatability due to early diet were still evident after the cattle had been fed to heavier (409 and 454 kg) weights. When steers weighing 409 and 454 kg were grouped together, the effects of feeding regimen during the intermediate period were considerably less pronounced than those of the early feeding period.

    Notes: SUMMARY: The role of cuticle (mucoprotein layer on the egg shell) in preventing spoilage of eggs by microorganisms was studied. Eggs collected from the uterus or eggs treated with 5% EDTA solution to remove cuticle spoiled at a much faster rate than the normally laid eggs. The weight of the egg shell and its membranes did not affect the spoilage of eggs collected from the uterus. The protection provided by the cuticle was found to last at least up to 96 hr after the eggs are laid.

    Notes: SUMMARY: The area most prone to infection and consequent spoilage of eggs was identified. Different areas of the egg were coated with paraffin wax. The waxed eggs were exposed to infection by Pseudomonas aeruginosa and spoilage studied by ultraviolet light candling. The blunt end was found to be most vulnerable followed by the equitorial region and the small end.

    Common Errors in Developing a Ground-Water Aquifer (1970)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 8 (1970), S. 0

    Notes: This paper presents some of the more common errors made in the development of ground-water supplies in the alluvial aquifers along the Ohio River in Kentucky. Ample available literature on proper methods of development of the alluvial aquifers generally seems to have been ignored by the water users in the area. The more common errors made in the typical developments are singled out for discussion.In the typical development the aquifer is treated as an inexhaustible underground river. Wells generally are clustered in small areas remote from the Ohio River, and are likely to be located more for convenience and economy of pipeline or property access than for hydrologic considerations. It is hoped by highlighting these errors and showing alternative methods of development that proper development practices will be fostered.Stages in the development of two hypothetical groundwater aquifers in the Ohio River valley are shown by eight illustrations that stress the common errors made in development and alternative methods of development taking into account hydrologic considerations.
