title: The Problems Confronting Small Utah Companies Seeking the First Increment of Public Equity Capital
Creators: name: Kerr, John A.
Publisher: name: Utah State University
Year: 1971

description: The objective of this research is to isolate and analyze those areas which represent the greatest difficulty in expense, ad ministrative burden and confusion. Information was gathered by survey and interviews to determine what services are offered by underwriting firms and what services small businesses have found most beneficial in planning and executing their offering. The information gathered in Utah is compared with that gathered in California to determine the differences in the public equity markets of the two regions. These differences are the bas i s for the recommended changes in the underwriting procedures in Utah.

description: Two ferromagnetic phases, FM1 and FM2, were first proposed to exist in LaCrGe$_3$ based on a broad maximum in the temperature derivative of resistivity resembling that of the superconducting ferromagnet UGe$_2$ where FM1 and FM2 are well-established. While evidence for two FM phases can be found in certain additional probes, corresponding anomalies in magnetization have not been recognized until now. Our spatially-resolved images of the magnetic domains show a substantial change in the domain structure between the higher temperature FM1 phase and the lower temperature FM2 phase. Furthermore, our measurements of the coercive field and virgin magnetization curves reveal an unconventional magnetic domain pinning region in the FM1 phase, followed by a depinning region at lower temperatures where the system is reported to crossover into the FM2 phase. We incorporate this discovery into a simple domain magnetization model that demystifies the magnetization curve seen in all previous studies. Finally, we find that the unusual domain behavior can be explained by a change in the ferromagnetic exchange interaction and magnetic moment, both of which are consistent with the existence of two FM phases. This revelation may help explain a range of anomalous behaviors observed in LaCrGe$_3$ and rekindles the discussion about the prevalence of multiple FM phases in fragile FM systems.

description: We study the accretion/ejection processes (i.e. disc/jet coupling) in the neutron star X-ray binary Aquila X-1 via a multi-wavelength approach. We use in the radio band the publicly available VLA archive containing observations of the object between 1986-2005, in the X-ray band the archival RXTE data (PCA and HEXTE) between 1997-2008, and in optical (R band) observations with the SMARTS recorded between 1998-2007. In the combined data set we find three outbursts for which quasi-simultaneous radio, optical (R band) and X-ray data exist and focus on them to some extent. We provide evidence that the disc/jet coupling in Aquila X-1 is similar to what has been observed in black hole X-ray binaries, at least from the point of view of the behaviour in the hardness-intensity diagrams (the hysteresis effect included), when the phenomenology of the jet is taken into account. Although based on a very small number of observations, a radio/X-ray correlation seems to exist for this system, with a slope of alpha=0.40 +/- 0.07 (F_{radio} \propto F_{X}^{alpha}), which is different than the slope of alpha=1.40 +/- 0.25 found for another atoll source, 4U 1728-34, but interestingly enough is relatively close to the values obtained for several black hole X-ray binaries. No significant correlation is found between the radio and optical (R band) emissions. We also report a significant drop in the radio flux from Aql X-1 above an X-ray flux of ~ 5 X 10^{-9} erg cm^{-2} s^{-1}. This behaviour, also reported in the neutron star X-ray binary 4U 1728-34, may be analogous to the suppression of radio emission in black hole X-ray binaries in bright, soft X-ray states. It suggests that from this point of view neutron star X-ray binaries can mimic the behaviour of black hole X-ray binaries in suppressing the jet in soft/disc-dominated X-ray states.

description: We have observed the low-mass protostellar source, IRAS 15398$-$3359, at a resolution of 0.$''$2-0.$''$3, as part of the Atacama Large Millimeter/Submillimeter Array Large Program FAUST, to examine the presence of a hot corino in the vicinity of the protostar. We detect nine CH$_3$OH lines including the high excitation lines with upper state energies up to 500 K. The CH$_3$OH rotational temperature and the column density are derived to be 119$^{+20}_{-26}$ K and 3.2$^{+2.5}_{-1.0}\times$10$^{18}$ cm$^{-2}$, respectively. The beam filling factor is derived to be 0.018$^{+0.005}_{-0.003}$, indicating that the emitting region of CH$_3$OH is much smaller than the synthesized beam size and is not resolved. The emitting region of three high excitation lines, 18$_{3,15}-18_{2,16}$, A ($E_u=$447 K), 19$_{3,16}-19_{2,17}$, A ($E_u=$491 K), and 20$_{3,17}-20_{2,18}$, A ($E_u=$537 K), is located within the 50 au area around the protostar, and seems to have a slight extension toward the northwest. Toward the continuum peak, we also detect one emission line from CH$_2$DOH and two features of multiple CH$_3$OCHO lines. These results, in combination with previous reports, indicate that IRAS 15398$-$3359 is a source with hybrid properties showing both hot corino chemistry rich in complex organic molecules on small scales $\sim$10 au) and warm carbon-chain chemistry (WCCC) rich in carbon-chain species on large scales ($\sim$100-1000 au). A possible implication of the small emitting region is further discussed in relation to the origin of the hot corino activity.

description: Varroa mites are serious pests of European honeybees (Apis mellifera). For detection of Varroa mite, a new molecular LAMP-based assay has been developed, which retains the body of the mite intact for morphological identification. Six novel Varroa LAMP primers were designed from existing DNA sequences of the COI locus to target V. destructor and V. jacobsoni, providing the ability to tell them apart from other non-target beehive associated mite and insect species. This LAMP assay is specific in detecting these Varroa species and has been tested on specimens originating from multiple countries. It produces amplification of V. destructor and V. jacobsoni in 16 ± 3.4 min with an anneal derivative of 78 ± 0.5 °C whilst another Varroa species,V. underwoodi, showed late amplification. A gBlock gene fragment, used here as a positive control has a different anneal derivative of 80 °C. Three non-destructive DNA extraction methods (HotShot, QuickExtract and Xtract) were tested and found to be suitable for use in the field. The LAMP assay was sensitive to very low levels of Varroa DNA, down to 0.24 picogram (~ 1 × 10 copies/µL of Varroa gBlock). This is a new molecular tool for rapid and accurate detection and identification of Varroa mites for pest management, in areas where these mites do not occur.

description: Non Abelian vortices of a SU(2) Chern-Simons--Higgs theory in 2+1 dimensions are constructed numerically. They represent natural counterparts of the U(1) solutions considered by Hong, Kim and Pac, and, by Jackiw and Weinberg. The Abelian embeddings are identified, for all values of the Higgs selfinteraction strength $ν$, resulting in both attractive and repulsive phases. A detailed analysis of the properties of the solutions reveals the existence ofa number of unexpected features. For a certain range of the parameter $ν$, it is shown that the non Abelian vortices have lower energy than their topologically stable Abelian counterparts, resulting in an effective energy lower bound on the SU(2) configurations. The angular momentum of these vortices is analysed and it is found that unlike the Abelian ones, whose angular momentum and energy are unrelated, there is a nontrivial mass--spin relation of the non Abelian vortices.

Stability conditions for fermionic Ising spin-glass models in the presence of a transverse field

description: The stability of spin-glass (SG) phase is analyzed in detail for a fermionic Ising SG (FISG) model in the presence of a magnetic transverse field $Γ$. The fermionic path integral formalism, replica method and static approach have been used to obtain the thermodynamic potential within one step replica symmetry breaking ansatz. The replica symmetry (RS) results show that the SG phase is always unstable against the replicon. Moreover, the two other eigenvalues $λ_{\pm}$ of the Hessian matrix (related to the diagonal elements of the replica matrix) can indicate an additional instability to the SG phase, which enhances when $Γ$ is increased. Therefore, this result suggests that the study of the replicon can not be enough to guarantee the RS stability in the present quantum FISG model, especially near the quantum critical point. In particular, the FISG model allows changing the occupation number of sites, so one can get a first order transition when the chemical potential exceeds a certain value. In this region, the replicon and the $λ_{\pm}$ indicate instability problems for the SG solution close to all range of first order boundary.

Possible effects of antimetabolites on virus replication
Creators: name: McMillan, Jeanette Margot
Publisher: name: University of British Columbia
Year: 2011

description: Because of the varied opinions and findings concerning the effect of cellular antimetabolites on the replication of both RNA and DNA-containing animal viruses, this project was undertaken to observe the effects of antimetabolites on Newcastle disease and vaccinia viruses: an RNA and a DNA virus respectively. The compounds chosen were the pyrimidine analogues 5-fltrorouracil and 5-iodo-deoxyuridine, and thioguanine, a purine antimetabolite. These compounds were chosen because they have already been shown to have growth inhibiting properties in other systems. Inhibition of virus replication was attempted rather than protection of cells, although some effort was made at the outset to determine the tolerance of the 10 - 12 day old chick embryo for the antimetabolites used in this study. The tolerance of the 10 - 12 day old chick was determined by inoculating the yolk sac of the developing embryo with the analogues and noting the survival time. The maximal concentration of the analogue which allowed 3 out of 4 embryos to survive for 48 hours at 37°c was the dose employed in the tests. Inoculation of the embryos with the virus was via the allantoic cavity or the chorio-allantoic membrane. Administration of the antimetabolite was made via the yolk sac either immediately after virus inoculation or if- hours later. After incubation for 36 - 48 hours at 37°C, the allantoic fluid and homogenized chorio-allantoic membranes were assayed to determine whether, there was any decrease in the production of virus-specific material in the presence of the antimetabolites. Tissue cultures of chick fibroblast cells infected with vaccinia virus were treated with antimetabolite and observed for noticeable changes. Nucleic acid analogues appear to vary in their inhibitory effects on different viruses. The enzymatic mechanism of the inhibitions seems to differ in different organisms. Antimetabolites may inhibit replication of DNA viruses and not of RNA viruses, or they may vary in degree and manner of inhibition among the DNA or RNA containing viruses themselves. 5-Fluorouracil was found to inhibit partially the replication of vaccinia virus in the chick embryo. The antimetabolite appeared to have no significant effect on the replication of Newcastle Disease virus. There were no observable differences in the titers of either virus harvested from thioguanine treated embryos as compared with-untreated embryos.

description: We study compact hidden charm pentaquarks in the Born-Oppenheimer approximation, previously introduced for tetraquarks, assuming the heavy pair to be in a color octet. We show that Fermi statistics applied to the complex of the three light quarks, also in color octet, requires S-wave pentaquark ground states to consist of three octets of flavour-SU(3)_f, two with spin 1/2 and one with spin 3/2, in line with the observed, strangeness S=0,-1, spectrum. Additional lines corresponding to decays into J/ψ+ Sigma and J/ψ+ Xi are predicted. In the language of non-relativistic SU(6), ground state pentaquarks form either a 56 or a 20 representation, distinguished by presence or absence of pentaquarks decaying in the spin 3/2 decuplet, e.g. in J/ψ+ Delta^++. Observation of a strangeness S=-2 or isospin I=3/2 pentaquarks would be a clear signature of compact, QCD bound pentaquarks.

Creators: name: Enright, Thomas W.
Publisher: name: Utah State University
Year: 1968

description: The prime interest of this study was to measure and analyze the authority/responsibility conceptions the program managers had of themselves as compared to that held by the line or functional personnel with whom the program managers were in day-to-day contact. A questionnaire consisting of 22 questions was distributed to 20 program managers and 73 line personnel. Of these 93 distributed questionnaires, 92 were returned and analyzed. The questionnaire asked to what degree, in the opinion of the respondent, did the program manager have the authority to perform 22 different functions. Categories of Always, Frequently, Seldom and Never were offered.
The hypothesis tested was that there was no difference between the conception the program manager held of his authority and responsibility as compared to what the line organization personnel held it to be. A chi square test was applied using a significant level of five percent to accept or reject the hypothesis. The Program Management responses were considered as the theoretical frequency and the line personnel responses as the observed frequency . The null hypothesis was accepted 59 percent of the time.
Percentage relationships of the responses to each question were also computed. On a percentage basis the program managers typically viewed their authority to be greater than did the line personnel.
The basic conclusion was that no clear pat tern of agreement emerged between the program managers and the line personnel as to the degree of authority held by the program manager and that the company involved i n the study should improve the authority/responsibility relationships involving the Program Management and line organization personnel.

description: The neutron superfluidity in the inner crust of a neutron star has been traditionally studied considering either homogeneous neutron matter or only a small number of nucleons confined inside the spherical Wigner-Seitz cell. Drawing analogies with the recently discovered multi-band superconductors, we have solved the anisotropic multi-band BCS gap equations with Bloch boundary conditions, thus providing a unified description taking consistently into account both the free neutrons and the nuclear clusters. Calculations have been carried out using the effective interaction underlying our recent Hartree-Fock-Bogoliubov nuclear mass model HFB-16. We have found that even though the presence of inhomogeneities lowers the neutron pairing gaps, the reduction is much less than that predicted by previous calculations using the Wigner-Seitz approximation. We have studied the disappearance of superfluidity with increasing temperature. As an application we have calculated the neutron specific heat, which is an important ingredient for modeling the thermal evolution of newly-born neutron stars. This work provides a new scheme for realistic calculations of superfluidity in neutron-star crusts.

description: The synthesis of Si3N4 nanowires from the reaction of silicon nanoparticles with N2 in the 1200-1440 C temperature range is reported. The nitridation conditions are such that the reaction with nitrogen is favoured by the presence of silicon oxide in the particles and by the active oxidation of silicon without a catalyst. It is shown that the Si to Si3N4 conversion rate depends on the amount of silicon particles used in the experiments and that, in general, the reaction slows down for greater amounts. This trend is explained by particle stacking, which restricts the exchange of gases between the furnace atmosphere and the atmosphere around the inner particles. In a first stage, local oxygen partial pressure increases around the inner particles and inhibits nitridation locally. If the amount of reactant Si nanoparticles is small enough, this extrinsic effect is avoided and the intrinsic nitridation kinetics can be measured. Experiments show that intrinsic kinetics does not depend on temperature.

There is need for new methods, strategies, and tools to facilitate those reviews. Here, we describe PACMan2, an updated tool for proposal review management that utilizes machine learning models and techniques to topically categorize proposals and reviewers, to match proposals to reviewers, and to facilitate proposal assignments, mitigating some conflicts of interest. We find that the classifier has cross-validation accuracy of $80.0\pm2.2\%$ on proposals for time on the Hubble Space Telescope and the James Webb Space Telescope.

description: Ancestral graphs can encode conditional independence relations that arise in directed acyclic graph (DAG) models with latent and selection variables. However, for any ancestral graph, there may be several other graphs to which it is Markov equivalent. We state and prove conditions under which two maximal ancestral graphs are Markov equivalent to each other, thereby extending analogous results for DAGs given by other authors. These conditions lead to an algorithm for determining Markov equivalence that runs in time that is polynomial in the number of vertices in the graph.

description: The cosmic origin of the elements, the fundamental chemical building blocks of the Universe, is still uncertain. Binary interactions play a key role in the evolution of many massive stars, yet their impact on chemical yields is poorly understood. Using the MESA stellar evolution code we predict the chemical yields ejected in wind mass loss and the supernovae of single and binary-stripped stars. We do this with a large 162 isotope nuclear network at solar-metallicity. We find that binary-stripped stars are more effective producers of the elements than single stars, due to their increased mass loss and an increased chance to eject their envelopes during a supernova. This increased production by binaries varies across the periodic table, with Fluorine and Potassium being more significantly produced by binary-stripped stars than single stars. We find that the C12/C13 could be used as an indicator of the conservativeness of mass transfer, as C13 is preferentially ejected during mass transfer while C12 is preferentially ejected during wind mass loss. We identify a number of gamma-ray emitting radioactive isotopes that may be used to help constrain progenitor and explosion models of core-collapse supernovae with next-generation gamma-ray detectors. For single stars we find V44 and Mn52 are strong probes of the explosion model, while for binary-stripped stars it is Cr48. Our findings highlight that binary-stripped stars are not equivalent to two single stars and that detailed stellar modelling is needed to predict their final nucleosynthetic yields.

description: The transport of heavy, neutral or charged, point-like particles by incompressible, resistive magnetohydrodynamic (MHD) turbulence is investigated by means of high-resolution numerical simulations. The spatial distribution of such impurities is observed to display strong deviations from homogeneity, both at dissipative and inertial range scales. Neutral particles tend to cluster in the vicinity of coherent vortex sheets due to their viscous drag with the flow, leading to the simultaneous presence of very concentrated and almost empty regions. The signature of clustering is different for charged particles. These exhibit in addition to the drag the Lorentz-force. The regions of spatial inhomogeneities change due to attractive and repulsive vortex sheets. While small charges increase clustering, larger charges have a reverse effect.

In the purely hydrodynamical models, we always obtain (at least) binary systems. When more than two stars are present, their gravitational interaction triggers mergers until there are two stars left. The following gas accretion increases their orbital separation and hierarchical fragmentation occurs so that both stars host a comparable disk and stellar system which then form similar disks as well. We identify several modes of fragmentation: Toomre-unstable disk fragmentation, arm-arm collision and arm-filament collision. Disks grow in size until they fragment and become truncated as the newly-formed companion gains mass. When including magnetic fields, the picture evolves: the primary disk produces less fragments, arm-filament collision is absent. Magnetic fields reduce the initial orbital separation but do not affect its further evolution, which is mainly driven by gas accretion. With magnetic fields, the growth of individual disks is regulated even in the absence of fragmentation or truncation. Conclusions. Hierarchical fragmentation is seen in unmagnetized and magnetized models. Magnetic fields, including non-ideal effects, are important because they remove certain fragmentation modes and limit the growth of disks, which is otherwise only limited through fragmentation.

description: A two-parameter family of complexity measures $\tilde{C}^{(α,β)}$ based on the Rényi entropies is introduced and characterized by a detailed study of its mathematical properties. This family is the generalization of a continuous version of the LMC complexity, which is recovered for $α=1$ and $β=2$. These complexity measures are obtained by multiplying two quantities bringing global information on the probability distribution defining the system. When one of the parameters, $α$ or $β$, goes to infinity, one of the global factors becomes a local factor. For this special case, the complexity is calculated on different quantum systems: H-atom, harmonic oscillator and square well.

description: This note is an extension of [DZ23] there the supersymmetric vacua of three-dimensional $\mathcal{N}=2$ gauge theories with matter are shown to be in one-to-one correspondence with the eigenstate of $\text{XXZ}$ integrable spin chain Hamiltonians with open boundary conditions. We consider the $A_{2}$ quiver gauge theory, which is the simplest non-trivial quiver gauge theory, and $sl_{3}$ open $\text{XXZ}$ spin chain with diagonal boundary condition. We demonstrate the correspondence between the vacuum equations of different gauge groups and Bethe Ansatz equations with different boundary parameters. Not only that, but we furthermore push forward the program to the general $A_{r}$ quiver gauge theory.

description: The Weyl double copy is a formula relating solutions of scalar, gauge and gravity theories, and is related to the BCJ double copy for scattering amplitudes. The latter relates Yang-Mills theory to ${\cal N}=0$ supergravity, where an axion and dilaton are present in addition to the graviton. However, the traditional Weyl double copy applies only to pure gravity solutions, such that it remains to be seen whether or not it can be extended to the full spectrum of ${\cal N}=0$ supergravity. We examine this question using recently developed twistor methods, showing that some sort of double copy formula for ${\cal N}=0$ supergravity is indeed possible for certain solutions. However, it differs both from the traditional Weyl double copy form, and recent conjectures aimed at generalising the Weyl double copy to non-vacuum solutions.

description: Petroleum product exposure is a known risk factor for respiratory diseases. This study investigated the effect of petroleum product inhalation on oxidative stress parameters and histopathological indices of the lung tissue of male Wistar albino rats. Forty-five rats aged 3 months and weighing 180–220 g were divided into five groups: Group A (Control), Group B (PMS exposure - 500 ml), Group C (Kerosene exposure - 500 ml), Group D (Diesel exposure - 500 ml), and Group E (Mixed petroleum products - 500 ml). The exposure lasted for 28 days, and lung tissue homogenate samples were collected at days 0, 14, and 28 to measure superoxide dismutase (SOD), catalase (CAT) activity and glutathione-s-transferase (GST) activity. The lungs were harvested using dissection to test the histological effects of the exposure. The results showed that SOD and CAT activity were significantly decreased (p<0.05) (11.12 ± 0.48 and 1.63 ± 0.23) when compared with the control (12.87 ± 0.93 and 3.29 ± 0.70) while GST activity significantly increased (p>0.05) (24.02 ± 0.54) compared with the control (23.20 ± 0.45). Histology of the lungs showing degeneration of the dentate granular layer in male Wistar albino rats exposed to diesel. These results emphasize the harmful effects of inhaling petroleum products on critical organ systems, particularly the lungs
On intersective polynomials with non-solvable Galois group

description: We present new theoretical results on the existence of intersective polynomials with certain prescribed Galois groups, namely the projective and affine linear groups $PGL_2(\ell)$ and $AGL_2(\ell)$ as well as the affine symplectic groups $AGSp_4(\ell):=(\mathbb{F}_\ell)^4 \rtimes GSp_4(\ell)$. For further families of affine groups, existence results are proven conditional on the existence on certain tamely ramified Galois extensions. We also compute explicit families of intersective polynomials for certain non-solvable groups.

title: A Survey for the Planning and Utilization of the Television Medium in Teaching Selected Courses at Utah State University and Continuing Education Centers in Utah
Creators: name: Taylor, Gordon M.
Publisher: name: Utah State University
Year: 1968

description: The purpose of this thesis was to survey facilities at Utah State University and the Uintah Basin Center, develop teaching utilization models which would operate in given situations, and identify problems and recommend areas for further study.
The investigator found the facilities presently used by the Uintah Basin Center adequate or nearly adequate for the use of instructional television. There are also classrooms and auditoriums at Utah State University which can be adapted for the use of television. However, equipment must be purchased in both localities . The Uintah Basin Center also must have a trained technician responsible for the equipment.
In view of the large number of students taking the televised courses each quarter, the investigator recommends the use of large screen projectors rather than monitors at Utah State University . This is not to say that courses taught by television with smaller enrollments per quarter should not use monitors.
The teaching utilization models developed by the investigator for the Uintah Basin Center and Utah State University were similar in nature, but each met the unique requirements for the institution for which it was designed.
As a result of the survey, this writer recommends the appointment of a coordinator for the whole project of determining the effective utilization of television at Utah State University, the Uintah Basin Center, and other continuing education centers as they may develop as a part of Utah State University's instructional program. He also recommends the development of a public relations program to stimulate interest in instructional tele-vis-ion and the development of utilization seminars to instruct those involved in television with effective ways of utilizing course material.
It is the opinion of the writer that the use of television instruction at continuing education centers and institutions of higher learning can be as good as it is planned to be . The success of instructional television is based upon the coordination of the entire television package. This coordination includes the detailed preparation of the physical classroom setting and courses of instruction designed to be effectively utilized in this classroom situation. The interweaving of these elements can provide effective student learning through instructional television.

Travel Time Shifts due to Amplitude Modulation in Time-Distance Helioseismology

description: Correct interpretation of acoustic travel times measured by time-distance helioseismology is essential to get an accurate understanding of the solar properties that are inferred from them. It has long been observed that sunspots suppress p-mode amplitude, but its implications on travel times has not been fully investigated so far. It has been found in test measurements using a 'masking' procedure, in which the solar Doppler signal in a localized quiet region of the Sun is artificially suppressed by a spatial function, and using numerical simulations that the amplitude modulations in combination with the phase-speed filtering may cause systematic shifts of acoustic travel times. To understand the properties of this procedure, we derive an analytical expression for the cross-covariance of a signal that has been modulated locally by a spatial function that has azimuthal symmetry, and then filtered by a phase speed filter typically used in time-distance helioseismology. Comparing this expression to the Gabor wavelet fitting formula without this effect, we find that there is a shift in the travel times, that is introduced by the amplitude modulation. The analytical model presented in this paper can be useful also for interpretation of travel time measurements for non-uniform distribution of oscillation amplitude due to observational effects.

Synthesis and characterization of 2'-adenosine diphosphate and 3'-adenosine diphosphate
Creators: name: Mitchel, Ronald E. J.
Publisher: name: University of British Columbia
Year: 2011

description: 2'-adenosine diphosphate and 3'-adenosine diphosphate were made from the corresponding unprotected nucleoside monophosphates using phosphoramidic acid. This synthesis of the pyrophosphate link was stimulated by pyridine. Both compounds were more labile than 5'-ADP, and they were shown to degrade by two separate routes. The degradation rate determining path seems to be cyclization with the vicinal hydroxyl, to form 2', 3'-cyclic AMP. A direct cleavage of the pyrophosphate link is an alternate slower route. Degradation curves at pH 3.5, 7.0 and in 7N ammonium hydroxide, at 100° C, are given. 3'-ADP was shown to be less stable than 2'-ADP at acid and neutral pH's, probably due to an increased nucleophilicity of the 2'-hydroxyl resulting from hydrogen bridging to the nitrogen in the 3 position of adenosine. Both compounds were found to be remarkably stable in 7N ammonium hydroxide at room temperature. The action of various enzymes was tested on these materials.. Bacterial alkaline phosphomonoesterase was active on both. Ribonuclease T₂ was active only on 3'-ADP and produced 3'-AMP. Snake venom diesterase and spleen diesterase were inactive on both.
