Abstract: A measurement of the underground muon decoherence function has been performed using the multiple muon events collected by the MACRO detector at the Gran Sasso National Laboratory. A detector-independent analysis is presented for different zenith regions and rock depths; this allows direct comparison with any model of hadronic interactions. The measured decoherence function is compared with the predictions of a Monte Carlo simulation based on data taken by recent collider experiments. © 1992 The American Physical Society.

Abstract: We report on the simultaneous observation of atmospheric erenkov light by a prototype five telescope array, GRACE, (Gran Sasso Air erenkov Experiment) with deep underground muons in the MACRO (Monopole Astrophysics and Cosmic Ray Observatory). The telescope array was deployed at Campo Imperatore above the Gran Sasso Laboratory for a run completed in the fall of 1992. The total live time for the combined surface-underground operation was ∼100 h during which more than 300 events were seen in coincidence. The efficacy of this technique to monitor the electromagnetic and penetrating muon components of a cosmic-ray-induced cascade is discussed. © 1994 The American Physical Society.

Abstract: Multimuon data from the MACRO experiment at Gran Sasso have been analysed using a new method which allows one to estimate the primary cosmic ray fluxes. The estimated all-particle spectrum is higher and flatter than the one obtained from direct measurements but is consistent with EAS measurements. The average mass number shows a weak dependence on the primary energy below 10^{6} GeV. Even within large uncertainties our data support a possible increase of the average mass number at higher energies.

Abstract: We present the analysis of multiple-muon events collected with one supermodule (1013 h live time) and two supermodules (1195 h live time) of the MACRO detector at Gran Sasso, Italy. Multimuon rates are shown to be sensitive to primary-cosmic-ray energies between 50 TeV and several thousand TeV. Experimental data are compared with the expected rates from two composition models: a light (i.e., proton-rich) and a heavy (i.e., Fe-rich) composition. The predictions are based on a Monte Carlo simulation of the hadronic interactions of cosmic-ray nuclei, followed by a detailed tracking of the muons through the rock and the experimental apparatus. The results show good sensitivity of the MACRO detector to primary composition. The data exhibit a preference towards the light composition model. © 1992 The American Physical Society.

Abstract: A negative search using 1/12 of the eventual MACRO detector has yielded nuclearite flux limits of 1.1[times]10[sup [minus]14] cm[sup [minus]2] sr[sup [minus]1] s[sup [minus]1] for 10[sup [minus]10][lt][ital m][lt]0.1 g, and 5.5[times]10[sup [minus]15] cm[sup [minus]2] sr[sup [minus]1] s[sup [minus]1] for [ital m][gt]0.1 g. We have modified the formula of De Rujula and Glashow for the light yield of nuclearites to include the uv light absorbed and reemitted in the visible region, and proved that the MACRO sensitivity extends almost to the escape velocity of the Earth. Our flux limit, therefore, can be used to address nuclearites that are possibly trapped in the solar system.

Abstract: The MACRO underground experiment has started a systematic experimental study of the structure of a very high multiplicity event sample, with the aim of gaining a better understanding of the features of the high energy showers. We present here two new analyses: a) the analysis of the distribution of the separation between pairs of high multiplicity muons (''decoherence'' function); b) the search for clusters of muons within high multiplicity events. The first results are discussed together with a comparison between the real data and the Monte Carlo predictions.

7. A phase II controlled study of a combination of the immune modulator, lentinan, with didanosine (ddI) in HIV patients with CD4 cells of 200-500/mm3

Subjects: Adult, Male, Didanosine, Lentinan, Adjuvants, Immunologic, Double-Blind Method, CD4 Antigens, Humans, Drug Therapy, Combination, Female, HIV Infections, Middle Aged
Abstract: This study was carried out to assess the safety and efficacy of a combination of lentinan, an immune modulator, and didanosine (ddI) in a controlled study in HIV positive patients with CD4 levels of 200-500 cells/mm3. Didanosine was administered to HIV patients at doses of 400 mg/day (po) for six weeks (bid), then 2 mg of lentinan i.v. was added per week for 24-80 weeks. A control group (20%) received ddI only. A total of 107 patients were enrolled at three sites, and 88 patients started the ddI/lentinan phase. The combination caused significant increases in CD4 levels up to 38 weeks, whereas ddI alone was significant at the 5% level at 14 weeks. Based on these data, lentinan qualifies as a participant in future multi-drug studies in HIV.

Abstract: The occupational health nurse is the primary workplace educator in the HIV pandemic. The policies and methods used to manage the employee with HIV must protect the confidentiality of the employee without discrimination. The occupational health nurse has a unique responsibility to monitor the disease progression and respond with appropriate recommendations for psychological support, AIDS resources, employee medical leave, and disability benefits. In addition, the occupational health nurse plays a pivotal role with the primary caregiver in clinical management of the employee at the worksite.

Abstract: Measurements of inclusive cross sections at 100 GeV/c are presented for the double-charge-exchange reactions a/sup +/p ..-->.. ..pi../sup -/X with a = ..pi.., K, or p. The measurements covered a kinematic range in the Feynman x variable of 0.3 < or = x < or = 0.9 at transverse momenta of 0.3 and 0.5 GeV/c. A model summing the contributions from resonance production and from inclusive central-region ..pi../sup -/ production is used to fit the data and demonstrates the importance of resonance production via one-pion exchange for large values of the Feynman x.

Abstract: The relative probability distribution of π±and π0 mesons in pp annihilation was measured in 10 MeV bins from 2.15 to 2.23 GeV. No significant variation in probabilities was found, and mean values are consistent with those reported at 2.28 GeV. Observed multiplicity distributions are consistent with two-body cascading on the statistical model under equal weighting of G = ±1 states.

The data were taken at 100 and 175 GeV/c incident momenta using the Fermilab Single-Arm Spectrometer operated over the kinematic range 0.2 < x < 1.0 and p/sub t/ < or = 1.0 GeV/c. Investigating the x dependence of the data, we find agreement with a quark-parton picture, namely the cross sections have a power-law behavior in 1 - x independent of p/sub beam/ and p/sub t/.

Abstract: The differential cross sections for the elastic scattering of ..pi../sup +/, ..pi../sup -/, K/sup +/, K/sup -/, p, and p-bar on protons have been measured in the t interval -0.04 to -0.75 GeV/sup 2/ at five momenta: 50, 70, 100, 140, and 175 GeV/c. The t distributions have been parametrized by the quadratic exponential form dsigma/dt = A exp( B abs. value(t) + C abs. value(t)/sup 2/ and the energy dependence has been described in terms of a single-pole Regge model. The pp and K/sup +/p diffraction peaks are found to shrink with ..cap alpha..' approx. 0.20 and approx. 0.15 GeV/sup -2/, respectively. The p-barp diffraction peak is antishrinking while ..pi../sup +/- and K/sup -/p are relatively energy-independent. Total elastic cross sections are calculated by integrating the differential cross sections. The rapid decline in sigma/sub el/ observed at low energies has stopped and all six reactions approach relatively constant values of sigma/sub el/. The ratio of sigma/sub el//sigma/sub tot/ approaches a constant value for all six reactions by 100 GeV, consistent with the predictions of the geometric-scaling hypothesis. This ratio is approx. 0.18 for pp and p-barp, and approx. 0.12--0.14 for ..pi../sup +/- and K/sup +/-. A crossover is observedmore » between K/sup +/p and K/sup -/p scattering at abs. value t approx =0.19 GeV/sup 2/, and between pp and p-barp at abs. value t approx=0.11 GeV/sup 2/. Inversion of the cross sections into impact-parameter space shows that protons are quite transparent to mesons even in head-on collisions. The probability for a meson to pass through a proton head-on without interaction inelastically is approx. 20%, while it is only approx. 6% for an incident proton or antiproton. Finally, the results are compared with various quark-model predictions.« less

Abstract: Data are presented on the inclusive production of ..pi../sup + -/, K/sup + -/, p, and p-bar for ..pi../sup +/, K/sup +/, and protons incident on nuclear targets at 100 GeV. The results cover the kinematic range 30< or =P< or =88 GeV/c for P/sub t/ = 0.3 and 0.5 GeV/c. The observed A dependence of the invariant cross sections exhibits remarkable simplicity, which does not naturally follow from current models of particle production. The results show that the hypothesis of limiting fragmentation can be extended to include collisions with nuclei.

Abstract: The MACRO detector is presently under construction, its installation at Gran Sasso being planned to start in September 1987. It is a large area detector, the acceptance for isotropic particle fluxes being around 10 000 m 2 sr, designed to search for rare phenomena in the cosmic radiation. It makes use of three detection techniques: liquid scintillator counters, plastic streamer tubes, and track-etch. It will perform a search for GUT monopoles (or any supermassive charged penetrating particle), a survey of cosmic point sources of HE gammas and neutrinos, a systematic study of the penetrating cosmic ray muons, and will be sensitive to neutrino bursts from gravitational stellar collapses in the Galaxy.

Abstract: We have analyzed a sample of 1.8 x 10(6) muons with E(mu) greater-than-or-similar-to 1.3 TeV collected by the first and second supermodules of the MACRO detector at Gran Sasso during the period 1989 February to 1991 February. We have searched for an excess of muons of celestial origin over cosmic-ray background. Our search for steady sources in solid angle bins of DELTAOMEGA almost-equal-to 3.0-degrees x 3.0-degrees in the declination range -5-degrees less-than-or-equal-to delta less-than-or-equal-to 90-degrees was negative; the upper limit with 95% C.L. to the muon flux at mid-latitudes (delta approximately 45-degrees) is J(mu)steady less-than-or-similar-to 2 x 10(-12) cm-2 s-1. In addition, we have searched for muon excesses modulated by the orbital period of selected X-ray sources, including Cyg X-3, Cyg X-1, Her X-1, 4U 0115+63, and 4U 1907+09. For Cyg X-3 we obtained an upper limit with 95% C.L. of J(mu)mod less-than-or-equal-to 8.8 x 10(-13) cm-2 s-1. Further, we have no evidence of any bursting activity from Cyg X-3, during our search period, which includes the radio outburst of 1991 January.

Abstract: We have performed a high-sensitivity search for massive long-lived particles produced at 2.5 mrad by 400-GeV/c protons on a beryllium target using time-of-flight, Cherenkov, and calorimetric techniques. A total of 10{sup 11} light particles ({pi}{sup -},K{sup -},{bar p}) was sampled at 70 GeV/c. This experiment places a limit of 1.1 x 10{sup -37} cm{sup 2}/(GeV/c){sup 2} {center_dot} nucleon on the invariant cross section for the production of stable particles in the mass range of 4 to 10 GeV/c{sup 2}.

Abstract: Impact-parameter representations of elastic differential cross sections for the processes ..pi../sup plus-or-minus/p, K/sup plus-or-minus/p, pp, and p-barp at incident energies from 50 GeV to 175 GeV and in the -t range 0.03--0.75 GeV/sup 2/ are presented. The meson-baryon interactions are found to be 20% more transparent than the baryon-baryon interaction, and to have an interaction radius which is 6% smaller. The increase in the p-p total cross section as a function of energy is shown to come primarily from an increase in the p-p interaction radius, while in the K/sup +/p case an increase is seen in both the central opacity and the interaction radius.

Abstract: In this paper, the first of a two-part work, we present the reconstruction and measurement of muon events detected underground by the MACRO experiment at Gran Sasso (E-mu greater than or equal to 1.3 TeV in atmosphere). The main aim of this work is to discuss the muon multiplicity distribution as measured in the detector. The data sample analyzed consists of 4.4 x 10(6) muon events, of which similar to 263 000 are multiple muons, corresponding to a total live time of 5850 h. In this sample, the observed multiplicities extend above N-mu = 35, with intermuon separations up to 50 m and beyond. Additional complementing measurements, such as the inclusive muon Aux, the angular distribution, and the muon separation distribution (decoherence), are also included. The physical interpretation of the results presented here is reported in the following companion paper.

32. A phase II controlled study of a combination of the immune modulator, lentinan, with didanosine (ddI) in HIV patients with CD4 cells of 200-500/mm3.

Author: Gordon M, Guralnik M, Kaneko Y, Mimura T, Goodgame J, DeMarzo C, Pierce D, Baker M, and Lang W
Subjects: Adult, Didanosine adverse effects, Double-Blind Method, Drug Therapy, Combination, Female, HIV Infections pathology, Humans, Lentinan adverse effects, Male, Middle Aged, Adjuvants, Immunologic therapeutic use, CD4 Antigens analysis, Didanosine therapeutic use, HIV Infections drug therapy, HIV Infections immunology, Lentinan therapeutic use
Abstract: This study was carried out to assess the safety and efficacy of a combination of lentinan, an immune modulator, and didanosine (ddI) in a controlled study in HIV positive patients with CD4 levels of 200-500 cells/mm3. Didanosine was administered to HIV patients at doses of 400 mg/day (po) for six weeks (bid), then 2 mg of lentinan i.v. was added per week for 24-80 weeks. A control group (20%) received ddI only. A total of 107 patients were enrolled at three sites, and 88 patients started the ddI/lentinan phase. The combination caused significant increases in CD4 levels up to 38 weeks, whereas ddI alone was significant at the 5% level at 14 weeks. Based on these data, lentinan qualifies as a participant in future multi-drug studies in HIV.

34. When an employee is HIV positive.

Author: DeMarzo C and Goodgame J
Subjects: Humans, HIV Infections nursing, Occupational Health Nursing methods, Patient Care Planning
Abstract: The occupational health nurse is the primary workplace educator in the HIV pandemic. The policies and methods used to manage the employee with HIV must protect the confidentiality of the employee without discrimination. The occupational health nurse has a unique responsibility to monitor the disease progression and respond with appropriate recommendations for psychological support, AIDS resources, employee medical leave, and disability benefits. In addition, the occupational health nurse plays a pivotal role with the primary caregiver in clinical management of the employee at the worksite.
