Spatial-Temporal Changes In Phytoplankton Biomass And Primary Production In Chwaka Bay, Zanzibar, M. N. S. Kyewalyanga

Tanzania Journal of Science

Spatial-temporal variations in phytoplankton primary production (PP) and biomass (B) were studied for a period of about one year, from July 1999 to July 2000. In addition, changes in corresponding environmental variables were examined. Sampling took place at two stations in Chwaka Bay, one located in mangrove areas, Station I, and the other in an open area, Station II. Although there were changes both with location and time, there were no clear seasonal trends. Generally, the phytoplankton biomass and primary production (mg C m-3 h-1) were higher at Station I than at Station II. However, specific production, that is, primary …

Absolute Migration And The Evolution Of The Rodriguez Triple Junction Since 75 Ma, D. C. P. Masalu

Tanzania Journal of Science

The Rodriguez Triple Junction (RTJ) is a junction connecting three mid-ocean ridges in the Indian Ocean: the Southwest Indian Ridge (SWIR), the Central Indian Ridge (CIR) and the Southeast Indian Ridge (SEIR). The evolution of the RTJ has been studied extensively for the past 10 Ma and the triple junction is believed to be largely a ridge-ridge-ridge (RRR) triple junction. However, due to the scarcity of data, its configuration prior to that period is poorly understood. The migration of the RTJ in the hotspot reference frame, for the past 75 million years has been mapped, by reconstructing its traces on …

Search For Radiative B,-Hadron Decays In Pp̅ Collisions At √S=1.8 Tev, Darin Acosta, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We have performed a search for radiative b-hadron decays using events produced in pp̅ collisions at √s=1.8 TeV and collected by the Collider Detector at Fermilab. The decays we considered were B̅_d⁰→K^*0(→K^-π⁺) γ, B̅_s⁰→φ(→K⁺K^-) γ, Λ_b⁰→ Λ(→pπ^-) γ, and their charge conjugates. Two independent methods to identify photons from such decays were employed. In the first method, the photon was detected in the electromagnetic calorimeter. In the second method, the photon was identified …

Limits On Extra Dimensions And New Particle Production In The Exclusive Photon, Darin Acosta, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

The exclusive γE/_T signal has a small standard model cross section and is thus a channel sensitive to new physics. This signature is predicted by models with a superlight gravitino or with large extra spatial dimensions. We search for such signals at the Collider Detector at Fermilab, using 87   pb^-1 of data at √s=1.8   TeV, and extract 95% C.L. limits on these processes. A limit of 221 GeV is set on the scale |F|^1/2 in supersymmetric models. For 4, 6, and 8 extra dimensions, model-dependent limits on the fundamental mass scale M_D of 0.55, 0.58, and …

Mylanodon Rosei, A New Metacheiromyid (Mammalia: Palaeanodonta) From The Late Tiffanian (Late Paleocene) Of Northwestern Wyoming, Ross Secord, Philip D. Gingerich, Jonathan I. Bloch

Department of Earth and Atmospheric Sciences: Faculty Publications

Mylanodon rosei is a new genus and species of late Paleocene metacheiromyid palaeanodont from a new late Tiffanian locality, Y2K Quarry, in the Clarks Fork Basin, Wyoming. The type is an adult dentary with P₄ and a molariform double-rooted M₁. This provides the first evidence that molariform teeth were retained in early Metacheiromyidae. A second specimen is a juvenile dentary with a partial P₃ and an unerupted P₄. This is the first juvenile dentition known for a Paleocene metacheiromyid. The new specimens enable determination of dental homologies. Reduction of teeth in early metacheiromyids took …

A Lightweight Coordination Model And Middleware For Mobile Computing **Please See Wucse-03-12**, Gruia-Catalin Roman, Chien-Liang Fok

All Computer Science and Engineering Research

LimeLite is a new coordination model and middleware designed to support rapid development of applications entailing logical mobility of agents and physical mobility of hosts. Designed to function in open environments, LimeLite performs automatic agent discovery but filters the results to define for each agent an individualized acquaintance list in accordance with run-time policies specified at the application level. This asymmetry among participants in the coordination process is dictated by the need to accommodate settings involving large numbers of agents and hosts that come and go freely. It represents an important departure from coordination research in general. The coordination context …

Secure Sharing Of Tuple Spaces In Ad Hoc Settings**Please See Wucse-03-26**, Gruia-Catalin Roman, Radu Handorean

All Computer Science and Engineering Research

Security is emerging as a growing concern throughout the distributed computing community. Typical solutions entail specialized infrastructure support for authentication, encryption and access control. Mobile applications executing over ad hoc wireless networks present designers with a rather distinct set of security requirements. A totally open setting and limited resources call for lightweight and highly decentralized security solutions. In this paper we propose an approach that relies on extending an existing coordination middleware for mobility (Lime). The need to continue to offer a very simple model of coordination that assures rapid software development led to limiting extensions solely to password protected …

Domestic Terror (The Sniper Suspect's Divorce Records Show Patterns Of Power And Control And Missed Opportunities By The System To Intervene.), Jane C. Murphy

All Faculty Scholarship

Over the past few months, we have learned much about the violent, troubled life of sniper suspect John Allen Muhammad. Whether or not he pulled the trigger - some recent reports have pointed to his 17-year-old companion Lee Boyd Malvo as the main shooter - there is no doubt in the minds of domestic-violence experts that this adult is responsible for these deaths.

While many pundits conclude that we will never know what motivated the sniper suspect, to domestic violence experts his is an all-too-familiar story of a man whose relationships with the women and children - possibly including Malvo …

The Design Of Reliable Protocols For Wireless Traffic Signal System, Qingfeng Huang, Ronald Miller

All Computer Science and Engineering Research

Electronic traffic signal has the advantage of being easily visible to machines. It is expected to augment the traditional traffic light system in future intelligent transportation environments, where intelligent vehicles interact with each other and with traffic systems and give informed advisories to drivers. One problem with wireless signals is that they are essentially omnidirectional. Even if one uses directional wireless signaling source, it is not clear how any recipient of a signal can reliably determine whether the signal is meant for him or her, in the presence of signal reflections. In this paper, we present a basic electronic traffic …

Perturbative Calculation Of The Triply Differential Cross Section For Photo-Double-Ionization Of He, Andrei Y. Istomin, N. L. Manakov, Anthony F. Starace

Anthony F. Starace Publications

Single-photon, two-electron ionization of He is analyzed, taking into account electron correlation using lowest-order perturbation theory and including all individual electron angular momenta in the final two-electron continuum. Perturbative account of electron correlation in the final state, which describes the so-called TS-1 mechanism of double photoionization, combined with a variational account of electron screening, is found to provide results for the triply differential cross section at an excess energy of 20 eV that are in excellent agreement with both absolute experimental data and results of non-perturbative calculations, for all kinematics of the process in which the TS-1 mechanism is expected …

Parts And Properties In Aristotle's Categories, Phil Corkum

The Society for Ancient Greek Philosophy Newsletter

Call a property recurrent if it can be found in more than one subject, and nonrecurrent otherwise. The question whether Aristotle holds that there are nonrecurrent properties has spawned a lively debate among recent commentators. An assumption held in common by both sides of the debate is that a property is nonrecurrent if it is inseparable from an individual subject. In this paper, I’ll argue that this assumption is false. There are a variety of kinds of separation in Aristotle. When we focus attention on what notion of separation is relevant, we will see that the inseparability possessed by individual …

Targeting Emotion In Early Stoicism, Scott M. Rubarth

The Society for Ancient Greek Philosophy Newsletter

The Stoic sage is a cold, heartless being who would not grieve over the loss of a beloved companion or child. Unmoved, unemotional, uncaring, the sage is an ethical and emotional monstrosity hiding behind the pretension of the so-called virtues of detachment and austerity. That, at least, is how many who study Stoic ethics perceive the sage in regard to his/her emotional life. In this paper I will argue that this conception of the Stoic theory of emotion and passion is misleading; emotions, in fact, are central to Stoic ethics and apatheia should not be confused with the contemporary idea …

Juvenile Clam Mortality Study At Three Intertidal Flats In Hampton Harbor, New Hampshire, Brian F. Beal

PREP Reports & Publications

Soft-shell clams, Mya arenaria L., represent an important recreational fishery along the New Hampshire coast. Intertidal flats in the Hampton-Seabrook Estuary are among the most heavily harvested. As recently as the fall of 1998, the sandy flats in this area supported more than 900 clammers, who, on weekends, easily harvested their 9.5-liter limit (Varney, 1999). Recently, however, quantitative benthic surveys have suggested that the abundance of adult clams (> 50 mm shell length, SL) has dwindled on the three estuarine flats (Brown’s Flat, Common Island, and Middle Ground). Clammers support this contention and many have been disappointed at the relative …

Hyperbolic Billiard Paths, Rebecca Lehman, Chad White

Mathematical Sciences Technical Reports (MSTR)

A useful way to investigate closed geodesics on a kaleidoscopically tiled surface is to look at the billiard path described by a closed geodesic on a single tile. When looking at billiard paths it is possible to ignore surfaces and restrict ourselves to the tiling of the hyperbolic plane. We classify the smallest billiard paths by wordlength and parity. We also demonstrate the existence of orientable paths and investigate conjectures about the billiard spectrum for the (2, 3, 7)-tiling.

Pigeon-Holing Monodromy Groups, Niles G. Johnson

Mathematical Sciences Technical Reports (MSTR)

A simple tiling on a sphere can be used to construct a tiling on a d-fold branched cover of the sphere. By lifting a so-called equatorial tiling on the sphere, the lifted tiling is locally kaleidoscopic, yielding an attractive tiling on the surface. This construction is via a correspondence between loops around vertices on the sphere and paths across tiles on the cover. The branched cover and lifted tiling give rise to an associated monodromy group in the symmetric group on d symbols. This monodromy group provides a beautiful connection between the cover and its base space. Our investigation …

Reflection Influence On Output Frequency Spectrum At Submillimeter Frequency Tunable Gyrotrons, Aripin Aripin, B. Kurniawan

Makara Journal of Science

Influence of output window reflections on oscillatory processes in gyrotrons has been studied. The processes in a gyrotron have been modeled numerically, and enhancement of the spectrum signal in the presence of reflections has been studied. Dependencies of output power versus time and frequency spectrum for different value of reflection coefficient are given. Possibilities of significant increasing of output spectrum are demonstrated experimentally. The results demonstrate significant influence of reflections on operation stability and composition of the output radiation of the gyrotron.
