TB33: Utilization of Amino Acids from Proteins: Manual of Procedures

To meet the protein needs of the newly developing countries and the increasing world population, plant proteins and protein mixtures will be required in larger and larger amounts. The proteins studied in this investigation included an animal and a vegetable protein that are important agricultural products of the United States. While general information about the nutritive quality of these proteins is available, this regional study was designed to contribute to an understanding of the reasons for the quality differences and to provide a basis for formulating protein mixtures of high quality using various protein sources.https://digitalcommons.library.umaine.edu/aes_techbulletin/1172/thumbnail.jp

Nisbah Sinkronisasi Suplai N-Protein Dan Energi Dalam Rumen Sebagai Basis Formulasi Ransum Ternak Ruminansia

The experiment was conducted to determine the optimum synchronization ratio of N-protein and fermented organic matter (OM) in the rumen for the purpose of ration formulation for ruminant animals, in order to improve efficiency of rumen microbial N synthesis and feed efficiency. Nylon bag technique was adopted to determine ruminal characteristic of protein and OM degradation of feedstuffs (forage and concentrate diet) for which the synchronized index of N-protein and fermented OM in the rumen might be determined. By randomized block design, twelve local cattle were arranged to four groups. Each group was fed three types of diet that was different in synchronization ratio of supplying N-protein and fermented OM in the rumen, namely 20 g N/kg OM (R20); 25 g N /kg OM (R25); and 30 g N /kg MO (R30). The diets had iso-energy and iso-protein contents and had the same synchronization index. The results showed that the type of diet had no effect (P>0.05) on intake and digestibility of nutrients, N retention, average daily gain (ADG), and feed efficiency. But R20 had better parameter values than those of R25 and R30. It might be concluded that the diet having a synchronization ratio of 20 g N/kg fermented OM in the rumen will generate more efficient protein synthesis of rumen microbes and feed efficiency

Career Experiences of Counselor Educators: Early and Near-Tenure Experiences

Counselor educators near the tenure years (5-10 years) experience challenges that differentiate them from their early and late career colleagues, regardless of tenure status. The following phenomenological study sought to ascertain the experiences of counselor education faculty during these distinct years of their academic careers. Eight counselor educators were interviewed and themes were derived, including a need for increased support pre- and post-tenure, adequate doctoral level preparation for faculty roles, and challenges in balancing the functions within and outside of the academy. Recommendations for current and emerging counselor educators are provided

Big data in healthcare: What is it used for?

Big data analytics is a growth area with the potential to provide useful insight in healthcare. Whilst many dimensions of big data still present issues in its use and adoption, such as managing the volume, variety, velocity, veracity, and value, the accuracy, integrity, and semantic interpretation are of greater concern in clinical application. However, such challenges have not deterred the use and exploration of big data as an evidence source in healthcare. This drives the need to investigate healthcare information to control and reduce the burgeoning cost of healthcare, as well as to seek evidence to improve patient outcomes. Whilst there are a number of well-publicised examples of the use of big data in health, such as Google Flu and HealthMap, there is no general classification of its uses to date. This study used a systemic review methodology to create a categorisation of big data use in healthcare. The results indicate that the natural classification is not clinical application based, rather it falls into four broad categories: administration and delivery, clinical decision support (with a sub category of clinical information), consumer behaviour, and support services. Further, the results demonstrate that the use of big data in all examples in the literature is not singular in its approach and each study covers multiple use and application areas. This study provides a baseline to assess the proliferation of the use of big data in healthcare and can assist in the understanding the breadth of big data applications

57-Fe Mossbauer study of magnetic ordering in superconducting K_0.85Fe_1.83Se_2.09 single crystals

The magnetic ordering of superconducting single crystals of K_0.85Fe_1.83Se_2.09 has been studied between 10K and 550K using 57-Fe Mossbauer spectroscopy. Despite being superconducting below T_sc ~30K, the iron sublattice in K_0.85Fe_1.83Se_2.09 clearly exhibits magnetic order from well below T_sc to its N\'eel temperature of T_N = 532 +/- 2K. The iron moments are ordered perpendicular to the single crystal plates, i.e. parallel to the crystal c-axis. The order collapses rapidly above 500K and the accompanying growth of a paramagnetic component suggests that the magnetic transition may be first order, which may explain the unusual temperature dependence reported in recent neutron diffraction studies.Comment: 6 pages, 4 figures Submitted to Phys.Rev.

Localization Properties of Electronic States in Polaron Model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers

We numerically investigate localization properties of electronic states in a static model of poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers with realistic parameters obtained by quantum-chemical calculation. The randomness in the on-site energies caused by the electron-phonon coupling are completely correlated to the off-diagonal parts. In the single electron model, the effect of the hydrogen-bond stretchings, the twist angles between the base pairs and the finite system size effects on the energy dependence of the localization length and on the Lyapunov exponent are given. The localization length is reduced by the influence of the fluctuations in the hydrogen bond stretchings. It is also shown that the helical twist angle affects the localization length in the poly(dG)-poly(dC) DNA polymer more strongly than in the poly(dA)-poly(dT) one. Furthermore, we show resonance structures in the energy dependence of the localization length when the system size is relatively small.Comment: 6 pages, 6 figure

Lead iodide X-ray and gamma-ray spectrometers for room and high temperature operation

In this study, we report on the results of the investigation of lead iodide material properties. The effectiveness of zone refining purification methods on the material purity is determined by ICP-MS and ICP-OES and correlated to the electrical and physical material properties. We show that this zone refining method is very efficient in removing impurities from lead iodide and we also determine the segregation coefficient for some of these impurities. Triple axis x- ray diffraction (TAD) analysis has been used to determine the crystalline perfection of the lead iodide after applying various cutting, etching, and fabrication methods. The soft lead iodide crystal was found to be damaged when cleaved by a razor blade, but by using a diamond wheel saw, followed by etching, the crystallinity of the material was improved, as observed by TAD. Low temperature photoluminescence also indicates an improvement in the material properties of the purified lead iodide. Electrical properties of lead iodide such as carrier mobility, were calculated based on carrier- phonon scattering. The results for the electrical properties were in good agreement with the experimental data

Charge Solitons in 1-D Arrays of Serially Coupled Josephson Junctions

We study a 1-D array of Josephson coupled superconducting grains with kinetic inductance which dominates over the Josephson inductance. In this limit the dynamics of excess Cooper pairs in the array is described in terms of charge solitons, created by polarization of the grains. We analyze the dynamics of these topological excitations, which are dual to the fluxons in a long Josephson junction, using the continuum sine-Gordon model. We find that their classical relativistic motion leads to saturation branches in the I-V characteristic of the array. We then discuss the semi-classical quantization of the charge soliton, and show that it is consistent with the large kinetic inductance of the array. We study the dynamics of a quantum charge soliton in a ring-shaped array biased by an external flux through its center. If the dephasing length of the quantum charge soliton is larger than the circumference of the array, quantum phenomena like persistent current and coherent current oscillations are expected. As the characteristic width of the charge soliton is of the order of 100 microns, it is a macroscopic quantum object. We discuss the dephasing mechanisms which can suppress the quantum behaviour of the charge soliton.Comment: 26 pages, LaTex, 7 Postscript figure
