Conflicting Ideals for Reorganization

Most of the recent literature dealing with reorganization and thereorganization amendments to the Bankruptcy Act has emphasizedreorganization procedure, and properly so. Abuses conceived to haveexisted in the past have been primarily procedural. The general tenorof reform objective has been to shift control over reorganization frominvestment bankers to the security holders themselves or to publicauthority

Ground-State Properties of a Model of a Two -Dimensional System of Liquid Helium Three

An investigation is made of the low temperature behavior of a two-dimensional many-fermion system parameterized to serve as a model of a mono-molecular layer of liquid He3. The calculations are made using the ∧oo approximation of the Martin-Schwinger thermodynamic Green\u27s function theory. A Herzfeld potential is used for the two body interaction in order that the resulting T matrix equation can be solved exactly. Three sets of the three parameters of this potential are chosen by requiring that they reproduce either the experimental and theoretical low temperature second virial coefficient, the phase shifts calculated from the six-twelve potential, or the experimental binding energy and density of the three-dimensional system. The chemical potential, energy per particle, density, and specific heat are calculated. Of the three sets of parameters the maximum binding energy for the two-dimensional system results from the potential which predicts the correct three-dimensional experimental energy and density. The maximum binding in this case is 1.1°K at a density corresponding to ro = 6.1 Å. Three-dimensional calculations were made with the several sets of parameters with the result that the virial coefficient and phase shift sets predict too little attraction

INDUCTION OF BONE MARROW COLONY-STIMULATING ACTIVITY BY A FILTERABLE AGENT IN LEUKEMIC AND NORMAL MOUSE SERUM

1. Leukemic Swiss mice of ICR/Ha strain which had been injected at birth with a lymphoid-leukemia-inducing virus preparation yielded sera which produced elevations of serum colony-stimulating activity within 16 hr and significant plasma-LDH-enzyme elevation at 4 days when injected intraperitoneally into normal ICR/Ha Swiss mice. Colony-stimulating activity was assayed in vitro by the stimulation of hemopoietic colony formation by DBA/1 bone marrow cells. 2. The inducing agent in leukemic serum was passageable, filterable, sedimentable, and heat-, ether-, and UV-labile. 3. A similar agent was recovered from normal Swiss serum after blind serial passages through normal mice. 4. LDH elevating virus induced a similar elevation of serum colony-stimulating activity when injected at high titers, and cross-resistance was demonstrated between LDH virus and the passaged leukemic serum agent

Crab pulsar giant pulses: Simultaneous radio and GRO observations

Observations are reported of the Crab pulsar made at radio frequencies concurrent with Oriented Scintillation Spectrometer Experiment (OSSE) observations from 15 to 27 May 1991. Using the 43 m telescope at Green Bank at 0.8 and 1.4 GHz, samples were made continuously for 10 hrs/day at intervals of 100 to 300 microsecs. The analysis of the radio data includes calculation of histograms of pulse intensities, absolute timing to about 20 microsec precision, and characterization of intensity variations on time scales from the 33 ms spin period to days. The most detailed analysis is presented made of giant pulses. The ultimate goal is to bin the radio data into giant and nongiant pulses and to form average waveforms of OSSE data for the corresponding pulse periods. A test is done to see whether the violet radio fluctuations (which are not seen in other radio pulsars to the same degree) are correlated with low energy gamma rays, yielding constraints on the radio coherence mechanism and the steadiness of the electron-positron outflow in the magnetosphere. Timing analysis of the radio data provides a well defined ephemeris over the specified range of epochs. The gamma ray pulse phase was predicted with an error of less than 70 microsecs

Factors leading to the establishment of child-headed households: the case of Zimbabwe

This paper analyses factors associated with the establishment of 43 child- and adolescent-headed households in Manicaland, Zimbabwe. Such households result from the rapid increase in numbers of parental deaths leading to overburdening of the capacity of relatives to fulfil their traditional role of caring for orphans. Most children living in child and adolescent headed households have had both parents die in the preceding five years; many of them receive regular visits and support from relatives. Child-headed households represent a new coping mechanism in response to the impact of AIDS on communities. Community groups can help extended families to cope with the burden of orphans by encouraging the establishment of volunteer-based visiting programs to atrisk households and by channelling essential material support to destitute families

Hydro-mechanical processing of brewer's spent grain as a novel route for separation of protein products with differentiated techno-functional properties

© 2019 Elsevier Ltd Hydro-mechanical processing using a colloid mill with a large gap setting leads to the preferential breakup of the residual aleurone and endosperm tissues of brewer's spent grain, forming a protein rich fines material with small particle size around 1–10 μm. This fraction can be separated from the coarser husk fraction by centrifugation, giving a protein product with enhanced techno-functional properties. The fines have good stability in aqueous suspensions, with potential for stabilising other particulate materials in food or drink formulations. The fines particles can stabilise oil-water emulsions, possibly through a Pickering mechanism, which may also support use in food applications. Fines suspensions have strong shear-thinning behaviour, which may be beneficial from a textural or transport perspective. Spray drying of fines suspensions is shown to avoid particle coalescence, which is important for effective resuspension on rehydration. The high surface area of the fines also leads to more efficient digestion by proteases. Industrial relevance: A novel hydro-mechanical milling process has been investigated for separation of a protein fine fraction from brewer's spent grain having enhanced techno-functional properties. The small particle size of the fines would be a key attribute for formulation in shake or smoothie products, where sensory attributes of the product would not be compromised and the properties of the fines could confer stability against settling. Applications may be found for the fines material as an ingredient in spreads and sauces or infant purees, in-particular where it might be used to stabilise of products based on oil-water emulsions. The market for protein-rich ingredients for foods and drinks is already established in the fitness and well-being market, as derived from other vegetable or cereal sources such as hemp, pea or rice. This controlled pre-milling step is also shown to lead to greater rate and extent of protease digestion of spent grain, which may be of value for generation of protein and peptide products for well-being and cosmetics applications

Effect of moisture content on thermal and water absorption properties of microfibrillar cellulose with polymeric additives

The aim of this study was 1) to investigate the influence of polymeric additives such as carboxyl methyl cellulose (CMC) and locust bean gum (LBG) added before and after homogenisation on the moisture uptake of microfibrillar cellulose (MFC) in the dry and semi-wet state; and 2) to further understand the thermally induced structural transitions of low moisture MFC in the presence of the polymeric additives. A higher moisture content in the highly dense MFC network maintains the fibrillated network structure, which is lost during the drying process resulting in MFC aggregates. The addition of polymeric additives results in the regaining of the structure upon redispersion of the dry material with CMC being more effective than LBG). Results also indicated that CMC has a high level of compatibility with MFC, whereas LBG appears to have limited distribution in the MFC dense microfibrillar network and probably exists as a separate phase when added after homogenisation, however co-processing of LBG and cellulose significantly changed this behaviour. The presence of low-temperature transitions in MFC/additives/water mixtures indicates the involvement of these semi-flexible polymeric additives in the formation of liquid crystals when added to MFC in low moisture environments (2% and 20% w/w). An insight is offered into the theory of surface interactions between MFC and polymeric additives, which prevents the agglomeration of microfibrils present in the highly fibrillated suspension upon drying

Search for B0s oscillations using inclusive lepton events

A search for B0s oscillations is performed using a sample of semileptonic b-hadron decays collected by the ALEPH experiment during 1991-1995. Compared to previous inclusive lepton analyses, the proper time resolution and b-flavour mistag rate are significantly improved. Additional sensitivity to B0s mixing is obtained by identifying subsamples of events having a B0s purity which is higher than the average for the whole data sample. Unbinned maximum likelihood amplitude fits are performed to derive a lower limit of Deltam_s>9.5ps^-1 at 95% CL. Combining with the ALEPH D-s based analyses yields Deltam_s>9.6ps^-1 at 95% CL.Comment: 23 pages, 10 figure
