    Accurate three-dimensional quantum scattering studies of long-lived resonances for the reaction He+H+2→HeH++H (1990)

    Notes: The adiabatically adjusting principal-axis hyperspherical (APH) formulation of Pack and Parker for quantum reactive scattering in three dimensions (3D) is used to obtain converged results for the reaction of helium with H+2 (v=1–4) for total angular momentum J=0. The ab initio potential energy surface computed by McLaughlin and Thompson and fitted by Joseph and Sathyamurthy is utilized for the HeH+2 interaction potential. The predicted energy dependence of the accurate 3D state-to-state reaction probabilities show clear evidence for quantum resonances. These resonances are even more numerous than those reported earlier for reduced dimensionality studies of this reaction. The calculated time delays for several of these resonances are found to be over 1 ps. Bending corrected rotating linear model (BCRLM) studies of this same reaction are also reported. These results provide useful insight in sorting out the nature and contribution of the resonances found in the 3D studies.

    Notes: Although it is not free from errors in detail, one of the considerable merits of Macaulay's History of England is the attention it gives to the newspaper Press and to the effects of the Licensing Act and of its expiry in 1695. More recently Dr de Beer has provided an admirable but brief account of the period from 1695 to 1702, but these explorations have served to open up rather than to exhaust the subject. In the present article also some interesting and important topics will have to be neglected, such as the advertisements in newspapers, the publication of literary and trade journals, and the politics behind die discontinuance of the Licensing Act in 1695.

    Forced convection ovens for reheating pre-cooked frozen food (1969)
    Oxford, UK : Blackwell Publishing Ltd
    International journal of food science & technology 4 (1969), S. 0 
    Details

    Notes: Summary. The importance of food pack thickness in forced convection ovens is shown in relation to production rates. For ovens operated on a batch basis, a pack thickness of 16 mm was recommended, and for ovens operated on a continuous basis, a pack thickness of 10 mm was recommended.A method for evaluating forced convection ovens was developed and applied for five commercially available ovens which were then compared. the ovens with fans external to the oven cavity and with the air flow ducted across the trays were superior to the ovens with fans built into the oven cavity. the fastest reheating was 25 min for the ducted air type and 35 min for the stirred air type. the most uniform reheating occurred in the ducted air type of ovens.

    Energy balance of an isolated scots pine (1980)

    Notes: Abstract The transpiration of an isolated Scots pine (P. sylvestris), determined by weighing, was related to stomatal resistance and environmental factors. The tree had been sheared to 1.5 m diameter at the base and 1.8 m high. The transpiration (2.97 MJ for 12h) was rather constant throughout the day and similar in shape to direct beam radiation incident upon the side of a cone. Transpiration rates calculated with the gradient equation duplicated measured values when vapor density gradients (obtained from measured needle temperature), measured stomatal resistance, and characteristic width of 3 mm in aerodynamic resistance were used in the calculations. Net radiation (Q*) for the tree was calculated by replacing the direct beam component of measured net radiation with the direct beam component incident upon a cone. The sensible heat flux, calculated with needle temperatures, was large (50.8 MJ) and nearly equal to Q* (53.85). The resulting Bowen ratio was 17. Transpiration calculated with a modified Penman-Monteith type equation simulated measured values.

    Forest fertilization research and practice in the Pacific Northwest (1991)
    Springer
    Nutrient cycling in agroecosystems 27 (1991), S. 129-140

    Keywords: Douglas-fir ; nitrogen ; mineral cycling ; growth and yield

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Forest managers in the Pacific Northwest (PNW) use fertilization as a means to increase timber yields in managed stands. Information on the biological basis for nutrient amendments and stand growth responses to fertilization is required to effectively use fertilization as a silvicultural tool, and research programs in mineral cycling and forest nutrition have been underway in the region for about four decades. Most PNW Douglas-fir forest sites are nitrogen deficient. Mineral cycling research has shown high C/N ratios and low nitrification rates for soils in the region. Research and development projects in the Pacific Northwest have produced an information base that is used to select sites and stands for fertilization and to forecast growth after treatment. Much of the basis for operational fertilization programs in western Oregon and Washington comes from cooperative research programs; current activities for these programs are directed toward improving site-specific response information. Forest fertilization in the Pacific Northwest has become a silvicultural practice of major significance over the past two decades. Forest industry and government organizations managing forest lands in western Oregon and Washington apply nitrogen fertilizer to Douglas-fir stands over a range of soil and stand types (operational fertilization of other species is minor). About 50,000 to 55,000 ha are fertilized each year, and future programs will likely be of similar magnitude. Most current plans for management regimes including fertilization call for multiple applications.

    Major-element deficiencies inCasuarina equisetifolia (1993)

    Notes: Abstract Casuarina equisetifolia is being widely used in tropical and sub-tropical countries as a fast-growing multipurpose tree. It is tolerant of relatively infertile sites, especially because of symbiotic N-fixation. However, mineral requirements and deficiencies have been scantily studied, even though responses to fertilization have been reported. To study its mineral nutrition, seedlings ofC. equisetifolia were grown for six months in sand cultures, using a 1/2 strength Hoagland-typeComplete solution, and two reduced levels of N, P, K, Ca, and Mg. Plant heights were measured every 2–3 weeks; at harvest, dry weights of younger and older foliage, stems, and roots were recorded, and chemical analyses made for the elements being studied. Deficiency symptoms were observed, and the chemical analyses confirmed at least incipient deficiency in the reduced level treatments for each of the five elements. This made possible estimation of deficiency ranges, which should be useful in assessing needs for mineral fertilization.
