    Summary The solid-substrate fermentation of wheat straw with an alkaliphilic white-rot fungus (Coprinus sp.) was found to be influenced by the levels of nitrogen, phosphorus+sulphur and free carbohydrates, in terms of biodegradation of straw ingredients, microbial protein production and changes in in-vitro dry matter digestibility (IVDMD). Nitrogen and Phosphorus+Sulphur compounds favoured the bioconversion and their optimum levels were (g/100 g DM): urea (sterile): 1.5, urea (unsterile): 3.0; superphosphate: 1.0. The addition of free carbohydrates as molasses and whey had detrimental effect on biodegradation of lignin as also on organic matter degradation and digestibility. However, the protein production was enhanced in the supplemented straw. The optimized laboratory fermentation was also extended to 4 kg-(sterile and unsterile) and 50 kg-(unsterile) fermentation.

    Abstract We report the first results on the determination of the ionization states of oxygen ions in the anomalous cosmic rays (ACR) from the measurements of their flux in the cosmic-ray experiment in Spacelab-3 (SL-3) mission of NASA flown at 350 km altitude during 29 April–6 May, 1985. The detectors used were specially prepared CR-39 plastics of very high sensitivity for recording tracks of ions withZ〉2. The measured orbit averaged flux of ACR oxygen is (2.9±1.3)×10−4 particles m−2sr−1s−1 (MeV N−1) at an energy of 23 MeV N−1. We made an independent estimate of the expected ACR oxygen flux at SL-3 orbit from interplanetary data and compared this with the measured flux to infer the ionization states of ACR oxygen ions. The flux and energy spectra of ACR oxygen at 1 AU outside the magnetosphere is obtained from the data of Voyager-2, during the same epoch as the SL-3 flight, and using the measured radial intensity gradient of 15%/AU for ACR oxygen between 1–17 AU. We calculate the geomagnetic transmission factors for ACR oxygen ions of charge states O+1, O+2, etc., from the known cut-off rigidities in the world grid and using the SL-3 trajectories for 116 orbits in the 6-day mission to obtain the expected flux at SL-3 for different charge states. When these flux values are compared with our measured flux, the averge ionization state of ACR oxygen ions in the energy interval of 20–26 MeV N−1 is obtained as O+1.

    Abstract In the present analysis the interactions of thermal and inertia effects on the performance of non-Newtonian squeeze films have been investigated. The numerical results for pressure drop and inertia correction in load have been obtained and their behaviours are illustrated in figures. The theoretically predicted results of pressure drop for the Newtonian lubricant have also been compared with experimental results of Tichy and Winer which are in close agreement at 70°F to illustrate the importance of the study.

    Abstract This paper discusses the results of a pot experiment conducted to study the effect of irrigation waters having varying Mg/Ca ratio (2, 4, 8 and 16) and electrolyte concentration (20 and 80 meq/l) on the soil properties and growth of wheat crop in two different soils. The development of salinity in the soils generally increased at higher electrolyte concentration of the irrigation water, but it was of a greater magnitude in the heavy-textured black soil dominated by montmorillonite clay mineral than in the light-textured alluvial soil having illite type of clay mineral. The accumulation of soluble salts as a result of saline water irrigation was higher in the surface layer than in the subsurface layer in both soils. The adsorption of Na and Mg in the soils increased with an increase in the Mg/Ca ratio and electrolyte concentration of the irrigation water. These changes in soil properties were adequately reflected by the grain and dry matter yields of wheat crop, which showed a significant reduction with an increase in the Mg/Ca ratio and electrolyte concentration of the irrigation water. However, the effects of these treatments were more pronounced in the heavy black clay soil than in the alluvial soil. Thus, the role of Mg is different from that of Ca under the conditions used in the experiment.

    Summary A study conducted in pots to evaluate the effect of different Mg/Ca ratios (2, 4, 8 and 16) and electrolyte concentrations (20 and 80 meq/l) at SAR 10 in irrigation water on the nutrient uptake and yield of wheat crop in two soils revealed that the average grain and dry matter yields of wheat decreased significantly with an increase in Mg/Ca ratio in irrigation water, but the magnitude of decrease was greater at higher electrolyte concentration than at lower electrolyte concentration. The concentration of Na in both straw and grain of wheat increased and that of K decreased with an increase in Mg/Ca ratio and electrolyte concentration of irrigation water, which led to higher Na/Ca and Na/K ratios in the plant. Further, the concentration of Ca and Mg both in straw as well as in grain increased with increasing electrolyte concentration of the irrigation water. An increasing proportion of Mg in saline irrigation water resulted in decreased concentration of Ca and increased concentration of Mg in both straw and grain of wheat crop. It was also noticed that the increasing proportion of Mg over Ca in the poor quality irrigation water increased the P content of both straw and grain of wheat crop.

    Notes:
    Abstract Chromosomes have been studied in seven species of bruchids belonging to the subfamilies Bruchinae and Amblycerinae. The diploid number of chromosomes is twenty in Bruchidius multilineolatus (Pic.), B. aureus Arora, B. saundersi (Jek.) and Conicobruchus indicus (Pic.); Bruchus pisorum L. and Specularius maindroni (Pic.) possess a diploid number of twenty-two whereas Spermophagus latescenta Arora has a diploid number of thirty-two. The male sex chromosome mechanism, however, is uniformly Xyp in all these species. The usual diplotene and diakinesis stages are not discrete in Bruchidius multilineolatus and Specularius maindroni. Instead, a “diffuse stage” is observed. A sticky anaphase bridge has also been observed in some cells of Bruchidius aureus.

    Abstract The morphology of chromosomes of two species of Silphidae and five species of Staphylinidae and the behaviour of chromosomes in mitosis and meiosis were studied. These staphylinoid beetles did not exhibit a ‘modal karyotype’. However, Xyp was found to be the most common male sex-chromosome mechanism althoughPhilonthus varius andQuedius fuliginosus possessed XO. Dicentric chromosomes were found inPhilonthus fuscipennis. Dicentrics were also found in both European and one East Siberian populations ofPhosphuga atrata. In the seven species, the diploid chromosome number ranged from 2n=24 to 2n=56. The evolution of karyotype and the interrelationships between species are dicussed.

    Summary Phanerochaete chrysosporium (ME-446) mineralized 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) in high N medium and in malt extract medium in which lignin peroxidases (LIPs) and manganese peroxidases (MNPs) are not produced; furthermore,per mutant of ME-446, which lacks LIPs and MNPs, mineralized 2,4,5-T as well as the wild type. These results indicate that LIPs and MNPs are not required for 2,4,5-T degradation byP. chrysosporium.

    The nonplanarity of a peptide unit has been studied by the ab initio method (GAUSSIAN 76) considering both the pyramidal structure of nitrogen and the variation of the ω angle for the N-methyl-acetamide and N-ethyl-acetamide in their cis and trans conformations. Several semiempirical methods have also been used for the sake of completeness of this work. All methods except CNDO and PCILO support a nonpyramidal structure for the nitrogen. The distortions of the planarity of the peptide unit show for both cis and trans conformations of the model compounds a significant asymmetric shift of the minimum on the energy curve for the ω rotation.

    Notes:
    Selected portions of the S0 and T1 potential energy surfaces of acetaldehyde surveyed in our earlier studies have been reexamined. The assumption of the additivity of basis-set polarization and of electron correlation effects used extensively in our earlier work on acetaldehyde has been tested through explicit polarized basis-set electron-correlation calculations. The “additivity assumption” introduces average absolute errors in energy differences of only 1.9 (MP3) to 3.4 (MP2) kcal mol-1 in seven comparisons. The effects of using 6-31G** SCF optimized geometries as opposed to single-point calculations on 3-21G SCF structures (6-31G**//3-21G) as in our previous papers were examined. In six comparisons, the average absolute error in relative SCF energies introduced by the use of the 3-21G geometries rather than the fully consistent 6-31G- ones was only 0.3 kcal mole-1. After a uniform scaling procedure, comparisons of the 6-31G** and 3-21G calculated vibrational frequencies with experiment for CH3CHO (S0), CH4, and CO (20 comparisons) yielded absolute differences of 41 cm-1 (6-31G**) and 57 cm-1 (3-21G). All these more elaborate calculations support for the specific case of acetaldehyde and various minima and transition states of relevance to its photochemistry, the commonly used and practically important approximations (e.g., additivity) made in our earlier studies.

    Notes:
    Bond orders and hybrid populations have been calculated from the density matrix localized in molecular space using similarity transformation for some fluorobenzene with the minimal basis set using Gaussian series of program. The ab initio bond orders and hybrid populations have been compared with the semiempirical calculations on this set of molecules. Also, these bond orders have been used in Coulson's bond order-bond length relationship to estimate bond lengths. The present calculations suggest that the qualitative predictions of molecular geometries are possible from these bond orders.
