    The title of the research is \u27\u27Lutherā€™s Principles of Education.ā€ The problem was to learn what the basic educational principles of Luther were. Through general reading, the writer had come to look upon Luther as a great educator as well as religious reformer. The purpose of this research, therefore, was to gather enough data on Lutherā€™s educational views as to be able to draw specific conclusions as to his over-all principles. After the data were gathered, the writer arranged these views under headings of major principles in a systematic manner

    Exploring the Multifaceted Nature of Complex Syntactic Units in Linguistic Texts

    Get PDF
    This research delves into the intricate realm of complex syntactic units, emphasizing their role as pivotal linguistic and methodological entities. By intertwining the planes of expression and content, the study underscores the structural and semantic markers that define these units. A comprehensive review of existing literature on the subject reveals the depth and breadth of understanding surrounding complex syntactic units. The paper further highlights the primary characteristics of these units, emphasizing their role in bridging individual sentences and facilitating coherent communication. Special focus is given to the concluding sentences within these units, which play a crucial role in connecting and contextualizing disparate sentences

    Automated analysis of 15N and 14C in biological samples

    Includes bibliographical references (page 947).An automated method for the simultaneous analysis of total N, total C, 15N and 14C in small plant and soil samples is described. A commercial C-N analyser - continuous flow isotope ratio mass spectrometer (ANCA-MS) has been extended to also measure CO2 and collect 14CO2 produced by sample combustion. Samples containing 20 - 200 Ī¼g N and up to 5 mg C can be analysed directly with no sample preparation other than drying and fine grinding. The precision of total elemental analysis is comparable to that by conventional methods. The average standard deviation of 15N analyses of plant material at natural abundance was Ā±1 ā€°. This is accurate enough for all 15N studies except those using natural abundance and possibly long term studies of soil organic matter. Recovery of 14C in test samples was 100%. The instrument can be operated by graduate students under supervision and operating costs are primarily for sample cups, combustion catalyst and quartz tubes

    Mineralizable soil nitrogen: amounts and extractability ratios

    Includes bibliographical references (page 80).Studies were conducted on a 15N-labeled Weirdale loam, a Dark Gray Chernozemic soil (Boralfic Boroll) to (i) determine the amounts of N released by several methods previously used to obtain an estimate of potentially mineralizable N, (ii) determine their 15N enrichment and extractability ratios, and (iii) compare the results from the above with the N mineralized during incubation and NH+4 released by the chloroform fumigation incubation technique. The NH+4-N accumulated during 10 d in fumigated soils accounted for āˆ¼1% of total N, was highly labeled, and had extractability ratios of 6.6 to 7.4. These ratios were similar to ones obtained for N mineralized during incubation of unfumigated soils. Ammonium-N extracted with dilute acidic permanganate solution (0.01M KMnO4 in 0.1 or 0.5M H2SO4) accounted for 0.72 to 0.84% of total N and had extractability ratios ranging from 3.4 to 3.9. A stronger solution of acidic permanganate extracted more N that was less enriched. Dilute sulfuric acid extracted NH+4 and organic N that had extractability ratios of < 3. Ammonium-N released by autoclaving the soil accounted for āˆ¼1% of total N and had extractability ratios ranging from 0.6 to 0.9. Acid hydrolysis showed that 72% of total N was hydrolyzable, 32% was amino acid-N and 20% was NH+4 released on hydrolysis. The extractability ratio for NH+4 released on hydrolysis was 1.7 and was significantly (P < 0.01) greater than extractability ratios of hydrolyzable N and amino acid-N. The similarity and high extractability ratios of NH+4 released after fumigation and NO-3-N accumulating during aerobic incubation indicated that the fumigation extracted a biologically meaningful fraction. The biomass was responsible for only 15 to 25% of the net N mineralized during a 12-week incubation. Results indicated that (i) extraction of a highly labeled N pool in soil can only partly explain the source of N being mineralized, (ii) N is mineralized from several pools, and (iii) there is a remote possibility that a single extractant can extract the variety of N compounds undergoing mineralization and immobilization in soil
