    A simple argument based on current algebra is given to show how monopoles can lead to baryon decay and other flavor-changing processes

    Comparison of production and composition of milk from cows grazing gahi-1 and Starr Pearl millets

    During midsummer, maintenance of milk flow is a problem to most dairy farmers. In general, shortage of high quality forage during the dry summer months reduces the milk yield. Permanent pastures in this area are usually less productive during this period. The varying topography, responsive soils and livestock potential offer wide scope to build up a year round pasture management program. The main objective should be to find an adapted species that has good persistency, disease resistance and a high yield in tonnage and total digestible nutrients for seasons. Gahi-1 and Starr and two varieties of pearl millet (Pennisetum glaucum) recently introduced for summer grazing in this area of the United States. Both varieties are known to have a wide range of soil adaptation, resistance to drought and foliage diseases and a high leaf-stem ratio. Absence of prussic acid gives more preference to them than other summer pastures and they are more productive than common pearl millet. Studies have been made comparing Sudan and pearl millets since the millets became popular in this area. But little work has been done to compare the various varieties of millets or to evaluate the quality of Gahi-1 and Starr on the basis of milk yield and composition, The future dairy industry has to face a problem of great economic interest. The fallacy, that regular intake of milk fat in the diet may predispose heart attack, prevails among a section of the milk consuming public. This fear may have created in many people the tendency to lower the intake of fat by decreasing the intake of fluid milk. The nutritional significance of milk fat – a powerful energy source of high caloric value has been underestimated. To avoid this dreadful disease, many have considered skim milk to be the safest for consumption. Today the per capita consumption of skim milk and other beverages containing milk solids - not - fat, has increased rapidly. Should we need milk laden with fat or total solids? Are the available methods of detecting fat and total solids accurate enough to satisfy the quality demands? To standardize dairy products and to satisfy quality demands and legal requirements, a correct estimation of both total solids and fat content of milk has become a routine in dairy plants. Several volumetric and gravimetric methods are in use for the determination of fat. The Cenco Moisture Balance and the Mojonnier are the two commonly used methods for the estimation of total solids. The use of the Babcock test for estimating the fat content has been universally accepted as a routine, reliable and quick method of the Mojonnier fat test method has been used to compare the accuracy of the Babcock method. The Cenco Moisture Balance was introduced recently in the dairy industry for the estimation of total solids and has not yet obtained official recognition. Varying results obtained, in other parts of this country, necessitated a repeated testing of the instrument as to its efficiency in estimating total solids when compared with other accepted methods like the Mojonnier. Results so far obtained in estimating total solids with the Cenco Balance seem to be quite encouraging and it holds promise for the near future. Simplicity in operation, less expense and saving of much labor and time are certain advantages with the instrument. The two objectives of this investigation were to find the relative summer feeding value of Gahi-1 and Starr millets in terms of milk yield, percent butterfat, percent total solids and body weight changes; and the relative efficiency of the Babcock versus the Mojonnier method for estimation of butterfat and the Mojonnier versus the Cenco Moisture Balance method for totally solids of milk samples collected from cows grazing Gahi-1 and Starr millets

    Second-order Phase Transitions, Inflationary Universe, and Formation of Galaxies

    Full text link
    At the critical point of a second-order phase transition, statistical fluctuations are correlated and enhanced in amplitude. We explore this phenomenon in the early universe as a possible mechanism for the formation of galaxies. In an inflationary universe, such dynamical effects on galactic scales are consistent with the constraints imposed by the horizon. Spontaneous breakdown of lepton number provides a model where these ideas are realized. The two-point correlation function for density fluctuations is calculated and agrees with the observed correlation for galaxies. An estimate of the density contrast is shown to be of the required magnitude

    Breakdown of Flavor Conservation in a Monopole Background

    We give a simple derivation of the catalysis of baryon decay and other flavor-changing processes by monopoles. The role of the axial anomaly is clarified. A general current-algebraic argument which clarifies the nature of flavor violation is also given

    Delay-insensitive ternary logic (DITL)

    This thesis focuses on development of a Single Rail Ternary Voltage Delay-Insensitive paradigm called Delay-Insensitive Ternary Logic (DITL), which is based on NULL Convention Logic (NCL). Single rail asynchronous logic has potential advantages over Dual-Rail logic such as reduction of Power and Interconnect as well as Logic Area. The DITL concept is developed in steps of individual circuit components. These components are designed at the transistor level and are connected together to form a registered pipeline system. Some variations in pipeline design are also investigated --Abstract, page iii

    Asthma Endotypes and an Overview of Targeted Therapy for Asthma

    Get PDF
    Guidelines for the management of severe asthma do not emphasize the measurement of the inflammatory component of airway disease to indicate appropriate treatments or to monitor response to treatment. Inflammation is a central component of asthma and contributes to symptoms, physiological, and structural abnormalities. It can be assessed by a number of endotyping strategies based on “omics” technology such as proteomics, transcriptomics, and metabolomics. It can also be assessed using simple cellular responses by quantitative cytometry in sputum. Bronchitis may be eosinophilic, neutrophilic, mixed-granulocytic, or paucigranulocytic (eosinophils and neutrophils not elevated). Eosinophilic bronchitis is usually a Type 2 (T2)-driven process and therefore a sputum eosinophilia of greater than 3% usually indicates a response to treatment with corticosteroids or novel therapies directed against T2 cytokines such as IL-4, IL-5, and IL-13. Neutrophilic bronchitis represents a non-T2-driven disease, which is generally a predictor of response to antibiotics and may be a predictor to therapies targeted at pathways that lead to neutrophil recruitment such as TNF, IL-1, IL-6, IL-8, IL-23, and IL-17. Paucigranulocytic disease may not warrant anti-inflammatory therapy. These patients, whose symptoms may be driven largely by airway hyper-responsiveness may benefit from smooth muscle-directed therapies such as bronchial thermoplasty or mast-cell directed therapies. This review will briefly summarize the current knowledge regarding “omics-based signatures” and cellular endotyping of severe asthma and give an overview of segmentation of asthma therapeutics guided by the endotype

    Relativistic Wave Equation For Anyons

    Full text link
    Construction of one-particle states as unitary representations of the Poincare algebra in 2 + 1 dimensions shows that an anyon has one polarization state. However, for nonzero spin manifestly linear and covariant realizations of Lorentz transformations require more than one field component, and an infinite number is needed when the value of spin is not an integer or half-integer. We discuss the relation between these two aspects of Poincare symmetry. In particular, we construct a relativistic equation for anyons where the number of physical polarizations is reduced to one by virtue of a gauge symmetry or equivalent constraint
