    This report documents all activity of the University of Miami Industrial Assessment Center (MIIAC) grant awarded by the United States Department of Energy (USDOE) Office of Energy Efficiency and Renewable Energy (EERE) Industrial Technology Program (ITP). This grant was coordinated through a collaborative effort with the Center for Advanced Energy Systems (CAES) located at Rutgers University in New Jersey (www.caes.rutgers.edu) which acted as the program’s Field Manager. The grant’s duration included fiscal years 2003-2006 (September 2002 – August 2006), and operated under the direction of Dr. Shihab Asfour, Director (MIIAC). MIIAC’s main goal was to provide energy assessments for local manufacturing firms. Energy consumption, productivity enhancement, and waste management were the focus of each assessment. Energy savings, cost savings, implementation costs, and simple payback periods were quantified using scientific methodologies and techniques. Over the four-year period of the grant, the total number of industrial assessments conducted was 91, resulting in 604 assessment recommendations and the following savings: 73,519,747 kWh, 435,722 MMBTU, and $10,024,453 in cost savings. A total of 16 undergraduate and graduate students were trained on energy assessment. Companies in over 40 different zip codes were assessed.

    The University of Miami (UM) has embarked on a very important and worthwhile mission: {open_quotes}To make UM one of the most energy efficient Universities in the Nation by the year 2000.{close_quotes} In order for the University to meet this goal we knew we would need to take advantage of all the available technologies and address the freon issues. In June 1990 the Coral Gables Campus had five chilled Water Production Plants, each representing small independent systems serving from four to ten buildings. Because of energy conservation measures of the past (i.e. elimination, reheat, first generation lighting retrofits, and some diversity), each plant had excess capacity. At that time we also had identified about 600 tons of old falling apart air conditioning equipment. Our Capital Construction Program was beginning design efforts for a new Music Recital Hall and an addition to the Law Library. With all this considered it made sense to develop a common chilled water loop to connect these plants and provide a vehicle to capitalize on available capacity. As this concept took shape it became evident that a master chilled water loop encircling the entire campus would address the next 20 years of campus development. This 20 year plan would require various phases of development. Phase I would connect three chilled water production plants and enable us to supply chilled water to seven existing facilities with approximately 600 tons of old inefficient air conditioning equipment and supply chilled water to the new Law and Music facilities, (approximately 400 tons) without buying any additional chillers.

    The University of Miami (UM) has embarked on a very important and worthwhile mission: ``To make UM one of the most energy efficient universities in the nation by the year 2000``. In order for the University to meet this goal the authors knew they would need to take advantage of all the available technologies and address the freon issues. In June 1990 the Coral Gables Campus had five chilled Water Production Plants, each representing small independent systems serving from four to ten buildings. Because of energy conservation measures of the past, each plant had excess capacity. At that time they also had identified about 600 tons of old falling-apart air conditioning equipment. The Capital Construction Program was beginning design efforts for a new Music Recital Hall and an addition to the Law Library. With all this considered it made sense to develop a common chilled water loop to connect these plants and provide a vehicle to capitalize on available capacity. In early 1991 Florida Power and Light offered a new CILC rate with criteria that the chilled water plants met. It allowed them to produce air conditioning at 5.8 cents a kWh, compared to 7.5 cents a kWh, at the buildings. This, added to the reality of not having to maintain or replace the old systems, made this the number 1 priority project. They were convinced that this could give them a competitive edge over other institutions because it insured that they could produce air conditioning at the least cost per square foot.

    2007-05-01

    Two recent major reports on the health of the oceans in the United States have warned that coastal development and population pressures are responsible for the dramatic degradation of U.S. ocean and coastal environments. The significant consequences of this increased population density, particularly in sub/tropical coastal regions, can be seen in recent weather events: Hurricanes Andrew, Ivan, and Katrina in the US Gulf of Mexico states, and the Tsunami in Southeast Asia in December 2004, all causing significant deaths and destruction. Microbial contamination, man-made chemicals, and a variety of harmful algal blooms and their toxins are increasingly affecting the health of coastal human populations via the seafood supply, as well as the commercial and recreational use of coastal marine waters. At the same time, there has been the realization that the oceans are a source of unexplored biological diversity able to provide medicinal, as well as nutritional, benefits. Therefore, the exploration and preservation of the earth's oceans have significant worldwide public health implications for current and future generations. The NSF/NIEHS Center for Oceans and Human Health Center (COHH) at the University of Miami Rosenstiel School and its collaborators builds on several decades of collaborative and interdisciplinary research, education, and training to address the NIEHS-NSF research initiative in Oceans and Human Health. The COHH focuses on issues relevant to the Southeastern US and Caribbean, as well as global Sub/Tropical areas worldwide, to integrate interdisciplinary research between biomedical and oceanographic scientists. The Center includes three Research Projects: (1) research into the application of toxic algal culture, toxin analysis, remote sensing, oceanography, and genomics to subtropical/tropical Harmful Algal Bloom (HAB) organism and toxin distribution; (2) exploring the interaction between functional genomics and oceanography of the subtropical

    Between October 1952 and February 1957, National Lead of Ohio (NLO), a primary contractor for the Atomic Energy Commission (AEC), subcontracted certain uranium machining operations to Alba Craft Laboratory, Incorporated, located at 10-14 West Rose Avenue, Oxford, Ohio. In 1992, personnel from Oak Ridge National Laboratory (ORNL) confirmed the presence of residual radioactive materials from the AEC-related operations in and around the facility in amounts exceeding the applicable Department of Energy (DOE) guidelines. Although the amount of uranium found on the property posed little health hazard if left undisturbed, the levels were sufficient to require remediation to bring radiological conditions into compliance with current guidelines, thus ensuring that the public and the environment are protected. Because it was suspected that uranium may have been used in the past in the immediate vicinity of Alba Craft in a Miami University building a team from ORNL, performed a radiological characterization survey of that structure in January 1994. The survey was conducted at the request of DOE as a precautionary measure to ensure that no radioactive residuals were present at levels exceeding guidelines. The survey included the determination of directly measured radiation levels and the collection of smear samples to detect possible removable alpha and beta-gamma activity levels, and comparison of these data to the guidelines. Results of the survey showed that all measurements were below the applicable guideline limits set by DOE.

    2004-04-01

    Pressures found in the biosphere (up to 1200 atm) have large effects on enzyme specificity and activity, molecular associations, protein folding, viral infectivity, and cellular morphology. The importance of pressure in pharmaceuticals, medical, and biomaterials sciences is beginning to be appreciated. Enzyme reactions under high pressure or in supercritical fluids may be promising in the synthesis of pharmaceuticals. High pressure processing of biopolymer networks may be important in producing matrices for biomaterials applications. In medicine, herpes, immunodeficiency viruses, and certain prion proteins are inactivated by pressure, which may be useful in the ex vivo treatment of blood. Even physiologically generated pressures, such as during colon peristalsis, have biological effects, for example, on the adhesion properties of epithelial cells in colon cancer. This presentation describes a new high-pressure structural and cellular biophysics laboratory under development at Miami University. Applications of specific methods, including high-pressure time-resolved fluorescence spectroscopy; high-pressure fluorescence microscopy; and high-pressure x-ray macromolecular crystallography will be discussed.

    Purpose: To describe University of Miami experience in the treatment of small cell carcinoma of the head and neck. Methods and Materials: A total of 12 patients with nonmetastatic small cell carcinoma of the head and neck were treated between April 1987 and September 2007. Radiotherapy was the primary local treatment modality for 8 patients. Results: Of the 12 patients, 8 had died after a median follow-up of 13 months. The 4 patients who were alive were followed for a median of 14 months. The Kaplan-Meier estimate of the proportion of small cell head-and-neck cancer patients surviving to 1 and 2 years was 63% and 26%, respectively. The percentage of patients remaining disease free at 1 and 2 years was 71% and 44%, respectively. The patients with tonsil/parotid gland cancer had significantly greater disease-specific survival compared with the other patients. The median survival time was 30 months in the tonsil/parotid group compared with 15.2 months in the other group (patients with small cell carcinoma of the sinonasal cavity, nasopharynx, and larynx). A total of 4 patients developed recurrence, 3 of whom had a distant failure component. The treatment modality was not associated with a difference in disease-specific survival. The 1-year disease-specific survival rate was 73% in the radiotherapy or radiotherapy/chemotherapy group compared with 67% in the other group. Conclusion: Radiotherapy with or without chemotherapy is a reasonable alternative to surgery for patients with small cell carcinoma of the head and neck. Patients with tonsillar or parotid small cell carcinomas did better than other sites. More aggressive treatment might be warranted for patients with sinonasal carcinoma. The outcome, however, continues to be suboptimal, and more effective therapy is needed because most patients had a component of local and distant failure.

    Anticipating pressing health care needs in the region, Florida International University (FIU) proposed the FIU College of Medicine (COM), which was approved by the Florida Board of Governors in March 2006. The FIU COM provides a program of study enabling graduates to pursue a wide spectrum of professional careers. This includes careers in general and subspecialty private practice, academic medicine, public service, health care, and public policy leadership. Irrespective of career choice, the special emphasis of the FIU COM mission is its focus on community health in a diverse metropolitan region. Clinical facilities are met through a public partner and multiple private hospital affiliations. Educational objectives are organized into five strands reflecting the breadth of medical education and running concurrently through the four-year curriculum: (1) human biology, (2) disease, illness, and injury, (3) clinical medicine, (4) professional development, and (5) medicine and society. Founding teaching faculty with expertise in the core basic sciences will not only introduce core scientific concepts during the initial seven months but reinforce these same concepts during organ system integrated courses and clerkships. The Neighborhood Health Education Learning Program is an FIU COM innovation in which each medical student is a member of a team that throughout the four-year curriculum identifies and addresses health care needs and factors affecting health outcomes. Preliminary approval of FIU COM was conferred in February 2008, with the first cohort of 40 students matriculating in August 2009. PMID:19881442

    Our universe can be described mathematically by a simple model developed in 1922 at Petrograd (St. Petersburg) by Alexander Friedmann (1888-1925). Without the benefit of observational evidence, Friedmann predicted that the whole universe would expand and evolve with time. This astonishing prediction was confirmed seven years later by Edwin Hubble. Its originator, unfortunately didn't live to savor this triumph. This vivid biography of an outstanding scientist sets his life and work against a wide backdrop of the history of cosmological studies and its major players, such as Einstein and others. The book is a window on Friedmann's school and university years, military service, and teaching and research during a seminal period of Soviet history. The authors include unique archival material, such as Friedmann's letters from the Russian Front, as well as contemporary records and reminiscences of colleagues. There is a detailed treatment of his work in theoretical cosmology (1922-1924), set in the context of the organization of Soviet science at the time.

    2002-01-01

    West of British Columbia, Canada, and south of the Yukon Territory, the southeastern coastline of Alaska trails off into the islands of the Alexander Archipelago. The area is rugged and contains many long, U-shaped, glaciated valleys, many of which terminate at tidewater. The Alexander Archipelago is home to Glacier Bay National Park. The large bay that has two forks on its northern end is Glacier Bay itself. The eastern fork is Muir inlet, into which runs the Muir glacier, named for the famous Scottish-born naturalist John Muir. Glacier Bay opens up into the Icy Strait. The large, solid white area to the west is Brady Icefield, which terminates at the southern end in Brady's Glacier. To locate more interesting features from Glacier Bay National Park, take a look at the park service map. As recently as two hundred years ago, a massive ice field extended into Icy Strait and filled the Glacier Bay. Since that time, the area has experienced rapid deglaciation, with many large glaciers retreating 40, 60, even 80 km. While temperatures have increased in the region, it is still unclear whether the rapid recession is part of the natural cycle of tidewater glaciers or is an indicator of longer-term climate change. For more on Glacier Bay and climate change, read an online paper by Dr. Dorothy Hall, a MODIS Associate Science Team Member. Credit: Jacques Descloitres, MODIS Land Rapid Response Team, NASA/GSFC

    The cause of the death of the Macedonian King, Alexander the Great, at Babylon in 323 BC has excited interest and conjecture throughout the ages. The information available in the surviving ancient sources, none of which is contemporaneous, has been reviewed and compared with modern knowledge as set out in several well-known recent surgical texts. The ancient sources record epic drinking by the Macedonian nobility since at least the time of Phillip II, Alexander's father. Alexander's sudden illness and death is likely to have resulted from a surgical complication of acute alcoholic excess.

    2009-03-01

    The dynamical properties of fractal networks have received wide range of attention. Works on this area by several pioneering authors^1-2 have led to the introduction of the spectral dimension that dictates the dynamic properties on a fractal lattice. Most of the studies involving spectral dimension have been performed on a type of fractal lattice known as percolation network. Alexander and Orbach^2 conjectured that the spectral dimension might be exactly 4/3 for percolation networks with Euclidean dimension de >= 2. Recent numerical simulations, however, could not decisively prove or disprove this conjecture, although there are other indirect evidences that it is true. We apply a stochastic approach^3 to determine the spectral dimension of percolation network for de >= 2 and check the validity of the Alexander-Orbach conjecture. Our preliminary results on 2- and 3-dimensional percolation networks indeed show that Alexander-Orbach conjecture is true, resolving a long-standing debate. References: 1. P.

    The accompanying articles that speculate that Alexander the Great had a traumatic carotid dissection or congenital cervical scoliosis demonstrate the difficulties in retrospective diagnosis as a historical enterprise. The extant primary sources were written centuries after Alexander's death and are ambiguous in their original languages, and even more so in translation. Thus we cannot be certain what illness Alexander actually had. Furthermore, anachronistic diagnosis removes Alexander from the medical context of this time, telling us little of historical significance about him. Such investigations also illustrate the more general limits that the absence of context imposes on the study of ancient history.

    2001-06-01

    Concentrating a wide range of spinal cord injury (SCI) research laboratories in a single location to accelerate progress and draw attention to the promise of SCI research has made The Miami Project to Cure Paralysis one of the most publicly recognized and often controversial research groups in the neurosciences. A "Center of Excellence" at the University of Miami School of Medicine, the Miami Project also serves as a model for SCI research programs being developed nationally and internationally. Founded in 1985, the Miami Project set out on an unprecedented path-to develop a research center dedicated to improving treatments for SCI by bridging basic and clinical science. In doing so, neurosurgeon Barth Green, M.D., enlisted not only a multidisciplinary team of scientists but also a devoted following of financial donors and volunteer research subjects, and support from the University of Miami and Florida legislature. Highly visible spokespersons, including cofounder ex-Miami Dolphin Nick Buoniconti and his son Marc, brought the issue of SCI paralysis and the promise of research before the public, the media, and sports communities. As progress in the neurosciences has raced ahead, public attention to medical research, and SCI research in particular, has grown exponentially. This review will assess the Miami Project as a model for disease-based research that unites academic, philanthropic, and patient communities in a common cause.

  5. A psychoanalytic study of Alexander the Great.

    PubMed

    Thomas, K R

    1995-12-01

    The purpose of this paper was to demonstrate how Freudian concepts such as the Oedipus complex, castration anxiety, fear of loss of love, the psychosexual stages of development, and the tripartite structure of personality can be used to understand the life and achievements of Alexander the Great. To accomplish this purpose, specific incidents, myths, and relationships in Alexander's life were analyzed from a Freudian psychoanalytic perspective. Green (1991), in his recent biography of Alexander, has questioned the merit of using Freudian concepts to understand Alexander's character. In fact, he stated specifically: If he (Alexander) had any kind of Oedipus complex it came in a poor second to the burning dynastic ambition which Olympias so sedulously fostered in him; those who insist on his psychological motivation would do better to take Adler as their mentor than Freud (p.56). Later, in the concluding section of his book, Green (1991, pp. 486-487) discounted Freudian interpretations of Alexander's distaste for sex, the rumors of his homosexual liaisons, his partiality for middle-aged or elderly ladies, and the systematic domination of his early years by Olympias as little more than the projected fears and desires of the interpreters. And again, an Adlerian power-complex paradigm was suggested as the preferable theoretical framework to use. Green's argument was based primarily on an exchange, reported originally by Plutarch, which took place between Alexander and Philip prior to Alexander's tutorship with Aristotle. Purportedly, Philip enjoined his son to study hard and pay close attention to all Aristotle said "so that you may not do a great many things of the sort that I am sorry I have done." At this point, Alexander "somewhat pertly" took Philip to task "because he was having children by other women besides his wife." Philip's reply was: "Well then, if you have many competitors for the kingdom, prove yourself honorable and good, so that you may obtain the

  9. Obituary: Donald Alexander Macrae, 1916-2006

    NASA Astrophysics Data System (ADS)

    Seaquist, E. R.

    2007-12-01

    With the passing of Donald Alexander MacRae on 6 December 2006 at age 90, the astronomy community lost a visionary scientist and a great educator in the field. Don MacRae was born in Halifax, Nova Scotia, on 19 February 1916, to Donald Alexander and Laura Geddes (Barnstead) MacRae. His father was originally a classics scholar and preceptor of Greek and Latin at Princeton, but at the time of Don's birth in 1916 he was Dean of the Dalhousie Law School in Halifax. The family moved to Toronto, Ontario, in 1924 when his father joined the faculty of Osgoode Hall Law School in Toronto as a Professor of Law. After the family moved to Toronto, where he received most of his early education, he obtained his undergraduate degree in Mathematics and Physics in 1937 from the University of Toronto (U of T). He obtained the degree of A.M. in 1940 and of Ph.D. in 1943 from Harvard University under the mentorship of Bart Bok in the field of galactic structure. During his early career he worked briefly at the University of Pennsylvania, Cornell University, and Carbide and Chemical Corporation at Oak Ridge, Tennessee. For Don the latter work was a brief and somewhat uneasy association with the Manhattan Project. In 1946, he obtained a position at Case Institute of Technology (now Case Western Reserve University), where he worked until 1953. In 1953, he accepted a position at the U of T, replacing Ralph Williamson, who had earlier introduced Don to the emerging field of radio astronomy while they both were at Cornell. Don's primary research field was stellar spectroscopy, but his interests were much broader than this, and he possessed an abiding ability to interest students and faculty in new and emerging ideas. In the early 1960s he developed a strong interest in the nature and origin of the lunar surface, and discussed these extensively with colleagues. Many of his ideas on this subject were later confirmed by the lunar exploration program. Don's continuing interest in radio astronomy

  10. GFAP and its role in Alexander Disease

    PubMed Central

    Quinlan, Roy A; Brenner, Michael; Goldman, James E.; Messing, Albee

    2009-01-01

    Here we review how GFAP mutations cause Alexander disease. The current data suggest that a combination of events cause the disease. These include: i) the accumulation of GFAP and the formation of characteristic aggregates, called Rosenthal fibres, ii) the sequestration of the protein chaperones αB-crystallin and HSP27 into Rosenthal fibres, and iii) the activation of both Jnk and the stress response. These then set in motion events that lead to Alexander disease. We discuss parallels with other intermediate filament diseases and assess potential therapies as part of this review as well as emerging trends in disease diagnosis and other aspects concerning GFAP.

    PubMed

    Vik, T

    1998-12-10

    Concert programmes and CD covers suggest that the Russian composer Alexander Borodin (1833-87) was also a great scientist. In this article we examine this proposition. Borodin was born in St. Petersburg as the illegitimate son of a Russian nobleman. As a boy his talents ranged from music to chemistry and languages. Borodin studied medicine at the Medico-Surgical Academy in St. Petersburg from 1850 to 1855 and defended his doctoral thesis on the similarity between arsenic and phosphoric acid in 1858. He did not, however, feel comfortable in his role as a doctor, and soon started to work as a chemist. In 1864 he was appointed professor of chemistry at the Medico-Surgical Academy. In 1861, Borodin attended the first international congress of chemistry in Karlsruhe, and he was among the founders of the Russian Chemical Society in 1868. He published 42 articles and was a friend of Dmitri Mendeleev, the scientist who described the periodic system. In 1872, Borodin started the first medical courses for women in Russia. It seems warranted to conclude that Alexander Borodin was indeed a great scientist and university teacher, though his immortality was earned by his leisure time activities. PMID:9914755

    2005-12-01

    Walter Alexander Feibelman, 79, an astronomer who discovered the E-ring of Saturn, died of a heart attack 19 November 2004 at his home at Riderwood Village in Silver Spring, Maryland. Walter was born 30 October 1925 in Berlin, Germany to Bernard and Dora Feibelman. He came to the United States with his parents in 1941. They were some of the last German Jews to flee Nazi Germany. Years later, he reported his experiences in an account contributed to the U.S. Holocaust Memorial Museum. As a youth, he worked at a cleaning shop and as a soda jerk before taking a course in tool and die making. He worked at the Abbey Photo Corp. in New York and in a model-making firm, where he constructed models of aircraft for use in identification courses by the Army Air Forces. After high school, he attended the Carnegie Institute of Technology and received his BS degree in 1956. Until 1969, he was a research scientist at the University of Pittsburgh. While working as an assistant research professor in physics and astronomy at the University of Pittsburgh in 1967, he examined a photo of Saturn taken a year earlier at the university's Allegheny Observatory. The E-ring -- unlike the bright main rings, A, B, C, D and F -- is faint and not easily spotted. He paired his observation with calculations and announced his discovery, which remained unconfirmed until the Pioneer 11 flyby in 1979. Walter joined the Optical Astronomy Division of Goddard Space Flight Center in Greenbelt in 1969, and worked there until 2002, when he became an emeritus astronomer at NASA. He became associated with the International Ultraviolet Explorer project, and worked on developing detectors for the orbiting observatory's spectrograph. The project turned out to be one of NASA's most successful observatories, operating from 1978 to 1996. In his scientific career, he published more than 200 refereed articles, mainly on hot stars and planetary nebulae. He also wrote papers in the fields of photography, spectroscopy

    NASA Astrophysics Data System (ADS)

    Dos Santos, P. M.; Matsuura, O. T.

    This is a biographical note on the life of Dr Alexander I. Postoiev, a victim of Stalin's purge of Soviet astronomers in 1936-1937 (McCutcheon, 1985). Along with his family, he left the Soviet Union in 1943, and lived in Germany as a refugee and "displaced person" until 1952, when he moved to Brazil. Then he started the second part of his professional career. Thanks to his efforts the Astronomical and Geophysical Institute (IAG) from the University of Sao Paulo (USP) was involved, for the first time, in programme of international cooperation, thus contributing to the institutional consolidation of IAG/USP as a leading centre of astronomical research and teaching today in Brazil.

    Alex Dalgarno's major contributions to the understanding of fundamental atomic and molecular processes enabled him to develop diagnostics of the physical conditions of atmospheres and astrophysical sources and to elucidate the roles of such processes in controlling those environments. He greatly influenced the research of physicists, chemists, atmospheric scientists, and astronomers, leading Sir David Bates to write, "There is no greater figure than Alex in the history of atomic physics and its applications." Alex was born and grew up in London. As a child, he enjoyed mathematical puzzles and did well at sports. He was invited to try out for the Tottenham Hotspur soccer team, but his professional sporting career ended due to an injury, which did not prevent Alex playing tennis and squash into his ninth decade. In 1945 Alex began to study Mathematics at University College London (UCL). In 1947 Sir Harrie Massey invited him to work for a PhD in Physics and suggested that Alex investigate collisions of metastable helium atoms in helium gas to determine the cross sections for excitation transfer. Richard Buckingham was Alex's immediate supervisor. After completing his graduate study in 1951, Alex became a member of staff in Applied Mathematics at the Queen's University of Belfast (QUB). He served as the Director of the Computational Laboratory after a 1954 visit to MIT, which had an electronic computer, led Alex to persuade colleagues that QUB needed one. In 1957, the poet Philip Larkin was the best man at the marriage of Alex to Barbara Kane. They had four children, Fergus, Penelope, Piers, and Rebecca, but the marriage dissolved after ten years. Alex's important work during the 1950s on the quantitative evaluation of long-range interactions underpinned his collaborations on precise scattering calculations relevant to ultra-cold collisions and the formation of atomic Bose-Einstein condensates over four decades later.

  2. "Most brilliant in judgment": Alexander the Great and Aristotle.

    From historical sources, it is evident that Alexander the Great was indebted to one of his teachers, Aristotle of Stagira. It was the teaching of Aristotle that evoked all the nascent talents of young Alexander and turned him into a great man. Alexander was extremely interested in the secrets of medicine and considered it an art. The medical knowledge he acquired from Aristotle may have saved his life and the lives of his troops on many occasions. If Alexander did not possess medical knowledge and if his everyday life had not been so greatly influenced by medicine, he might never have been able to create his empire.

  12. Alexander's disease: clinical, pathologic, and genetic features.

    Johnson, Anne B; Brenner, Michael

    2003-09-01

    Alexander's disease, a rare and fatal disorder of the central nervous system, most commonly affects infants and young children but can also occur in older children and sometimes adults. In infants and young children, it causes developmental delay, psychomotor retardation, paraparesis, feeding problems, usually megalencephaly, often seizures, and sometimes hydrocephalus. Juvenile cases often do not have megalencephaly and tend to have predominant pseudobulbar and bulbar signs. In both groups, characteristic magnetic resonance imaging findings have been described. In adult cases, the signs are variable, can resemble multiple sclerosis, and might include palatal myoclonus. In all cases, the examination of brain tissue shows the presence of widely distributed Rosenthal fibers. Almost all cases have recently been found to have a heterozygous, missense, point mutation in the gene for glial fibrillary acidic protein, which provides a new diagnostic tool. In most cases, the mutation appears to occur de novo, not being present in either parent, but some adult cases are familial.

    Miami International Airport (MIA) is endeavoring to essentially double its traffic volume by the turn of the century. This is a great challenge since the site is already highly developed. Space, safety and other constraints make it difficult to implement conventional detention/retention stormwater practices. Other practices were evaluated to control stormwater quantity/quality, since some of the downstream bodies of water are flood-prone or environmentally sensitive.

  16. The death of Alexander the Great: malaria or typhoid fever?

    PubMed

    Cunha, Burke A

    2004-03-01

    Alexander the Great had a profound effect on world history. His conquests covered the entire known world at the time, and he was responsible for the spread of Greek culture throughout the ancient world. In Babylon in 323 BC, Alexander died when he was nearly 33 years old. Possible explanations for his death have included alcoholic liver disease and strychnine poisoning, but little data support either condition as the cause of his death. Alexander most likely died from malaria or typhoid fever, which were rampant in ancient Babylon. The description of his final illness from the royal diaries is consistent with typhoid fever or malaria but is most characteristic of typhoid fever.

    We present the case of a Japanese male infant with Alexander disease who developed infantile spasms at 8 months of age. The patient had a cluster of partial seizures at 4 months of age. He presented with mild general hypotonia and developmental delay. Macrocephaly was not observed. Brain magnetic resonance imaging (MRI) findings fulfilled all MRI-based criteria for the diagnosis of Alexander disease and revealed mild atrophy of the dorsal pons and medulla oblongata with abnormal intensities. DNA analysis disclosed a novel heterozygous missense mutation (c.1154 C>T, p.S385F) in the glial fibrillary acidic protein gene. At 8 months of age, tonic spasms occurred, and electroencephalography (EEG) revealed hypsarrhythmia. Lamotrigine effectively controlled the infantile spasms and improved the abnormal EEG findings. Although most patients with infantile Alexander disease have epilepsy, infantile spasms are rare. This comorbid condition may be associated with the distribution of the brain lesions and the age at onset of Alexander disease.

  1. What is the alternative to the Alexander-Orbach relation?

    NASA Astrophysics Data System (ADS)

    Sokolov, Igor M.

    2016-03-01

    The Alexander-Orbach (AO) relation d w = 2d f /d s connecting the fractal dimension of a random walk’s (RW) trajectory d w or the exponent of anomalous diffusion α = 2/d w on a fractal structure with the fractal and spectral dimension of the structure itself plays a key role in discussion of dynamical properties of complex systems including living cells and single biomolecules. This relation however does not hold universally and breaks down for some structures like diffusion limited aggregates and Eden trees. We show that the alternative to the AO relation is the explicit dependence of the coefficient of the anomalous diffusion on the system’s size, i.e. the absence of its thermodynamical limit. The prerequisite for its breakdown is the dependence of the local structure of possible steps of the RW on the system’s size. The discussion is illustrated by the examples of diffusion on a Koch curve (AO-conform) and on a Cantor dust (violating AO relation).

    A view looking east shows the cities from Hollywood to Homestead in the greater Miami area. The photograph is centered directly over the city of Miami at approximately 25.5 degrees north and 80.5 degrees west. The average elevation of the area is 6 feet above mean sea level. Extensive drainage has taken place since the late 19th century to prevent massive flooding. The Miami River is one of the main drainage structures and is visible as a straight diagonal line near the center of the picture. Many of the small lakes in the lower portion of the view are catch ponds for runoff water. Many of the major roads are visible: Highway A1A follows the coast and ends at Miami Beach. Interstate 95 parallels the coast. The Taniami trail to the west across the Everglades (center-bottom) links Miami Beach to the mainland.

    PubMed

    Berkman, Julia M

    2005-01-01

    This article examines the life and work of Alexander Francis Chamberlain. Though he has received little attention since the early 1900s, the importance of this scholar should not be underestimated. Chamberlain made notable contributions to the body of knowledge in anthropology-a discipline that, at the time, was a combination of anthropological and psychological inquiry. His early work began with investigations into the cultures and languages of two Indian tribes indigenous to Canada and the northern United States and, within a few decades, positioned Chamberlain as the leading scholar in this domain. Beyond his ethnographic insights, Chamberlain queried the development of the child and wrote on the subject of childhood in world folklore. He concerned himself with a scope of worthwhile subjects ranging from linguistics to women's suffrage. No topic was out of range as all forms of human study addressed the need for seeing each group as a contributing force to humanity at large. Chamberlain emphasized that no single racial, ethnic, or religious group should be singled out as inherently superior to another, a belief far ahead of his time. This article is an attempt at drawing a picture of a man whose scholarly achievements and strength of character are captured in the depth and breadth of his writing. PMID:17549937

  9. Alexander disease: a review and the gene.

    PubMed

    Johnson, Anne B

    2002-01-01

    This review presents historical and clinical information on the rare human brain disorder known as Alexander disease (ALX), and reports on the recent discovery of the gene that appears to be causative. The disease is a fatal, white matter disorder (leukodystrophy) of childhood. Adult onset cases also have been described, but it has not been clear whether they represent the same disease. Until recently the diagnosis was made by the pathological examination of brain tissue, in which abundant Rosenthal fibers were found. These abnormal structures occurred within astrocytes, but their composition was unclear. In 1985, a child underwent a diagnostic brain biopsy at this institution, which established the diagnosis of ALX. Ultrastructural immunocytochemistry revealed that the Rosenthal fibers contained abundant amounts of glial fibrillary acidic protein (GFAP), a normal component of astocytic intermediate filaments. Thus, the gene for this filament protein was considered a candidate gene for the cause of ALX, and DNA samples from children presumed or proven to have this disorder were banked for future study. Other work on the same brain biopsy showed that Rosenthal fibers also contained abundant alphaB-crystallin, a heat shock protein, but no defect was found in its gene. A decade after the biopsy, a transgenic mouse with an extra copy of the gene for GFAP was produced. These mice died early and their brains contained Rosenthal fibers. Although not an exact model for ALX, this also suggested that the gene for GFAP should be considered a candidate gene for ALX. Subsequent research has demonstrated that the great majority of childhood ALX cases contain mutations in the gene for GFAP. This work is now being extended as a diagnostic test, as well as to seek understanding of the pathogenesis of ALX and possible approaches for treatment.

  10. Stratigraphy of the Upper Pleistocene Miami Limestone of Florida

    Zanvil Alexander Cohn, an editor of this Journal since 1973, died suddenly on June 28, 1993. Cohn is best known as the father of the current era of macrophage biology. Many of his scientific accomplishments are recounted here, beginning with seminal studies on the granules of phagocytes that were performed with his close colleague and former editor of this Journal, James Hirsch. Cohn and Hirsch identified the granules as lysosomes that discharged their contents of digestive enzymes into vacuoles containing phagocytosed microbes. These findings were part of the formative era of cell biology and initiated the modern study of endocytosis and cell-mediated resistance to infection. Cohn further explored the endocytic apparatus in pioneering studies of the mouse peritoneal macrophage in culture. He described vesicular inputs from the cell surface and Golgi apparatus and documented the thoroughness of substrate digestion within lysosomal vacuoles that would only permit the egress of monosaccharides and amino acids. These discoveries created a vigorous environment for graduate students, postdoctoral fellows, and junior and visiting faculty. Some of the major findings that emerged from Cohn's collaborations included the radioiodination of the plasma membrane for studies of composition and turnover; membrane recycling during endocytosis; the origin of the mononuclear phagocyte system in situ; the discovery of the dendritic cell system of antigen-presenting cells; the macrophage as a secretory cell, including the release of proteases and large amounts of prostaglandins and leukotrienes; several defined parameters of macrophage activation, especially the ability of T cell-derived lymphokines to enhance killing of tumor cells and intracellular protozoa; the granule discharge mechanism whereby cytotoxic lymphocytes release the pore-forming protein perforin; the signaling of macrophages via myristoylated substrates of protein kinase C; and a tissue culture model in which

    I propose that Alexander the Great died of acute pancreatitis secondary to heavy alcohol consumption and a very rich meal. The cause of death of prominent historic or artistic figures attracts considerable interest of historians and researchers. This is especially the case for Alexander the Great. More than 20,000 publications, books, or monographs on the life and work of Alexander the Great have been published. There are several theories and hypotheses regarding the cause of his death, that are based on historic descriptions, diaries, notations, and interpretations of events. It is inevitable that history and myth intermingle in any investigative approach, no matter how scholarly. In this article, on the basis of several historic sources. I have made an effort to reconstruct the final 14 days of his life and record the course of medical events that preceded his death with the formulation of a plausible diagnosis.

    Alexander the Great died in Babylon in 323 BC. His death at age 32 followed a 2-week febrile illness. Speculated causes of death have included poisoning; assassination, and a number of infectious diseases. One incident, mentioned by Plutarch but not considered by previous investigators, may shed light on the cause of Alexander's death. The incident, which occurred as he entered Babylon, involved a flock of ravens exhibiting unusual behavior and subsequently dying at his feet. The inexplicable behavior of ravens is reminiscent of avian illness and death weeks before the first human cases of West Nile virus infection were identified in the United States. We posit that Alexander may have died of West Nile virus encephalitis.

  11. A complex-network perspective on Alexander's wholeness

    NASA Astrophysics Data System (ADS)

    Jiang, Bin

    2016-12-01

    The wholeness, conceived and developed by Christopher Alexander, is what exists to some degree or other in space and matter, and can be described by precise mathematical language. However, it remains somehow mysterious and elusive, and therefore hard to grasp. This paper develops a complex network perspective on the wholeness to better understand the nature of order or beauty for sustainable design. I bring together a set of complexity-science subjects such as complex networks, fractal geometry, and in particular underlying scaling hierarchy derived by head/tail breaks - a classification scheme and a visualization tool for data with a heavy-tailed distribution, in order to make Alexander's profound thoughts more accessible to design practitioners and complexity-science researchers. Through several case studies (some of which Alexander studied), I demonstrate that the complex-network perspective helps reduce the mystery of wholeness and brings new insights to Alexander's thoughts on the concept of wholeness or objective beauty that exists in fine and deep structure. The complex-network perspective enables us to see things in their wholeness, and to better understand how the kind of structural beauty emerges from local actions guided by the 15 fundamental properties, and in particular by differentiation and adaptation processes. The wholeness goes beyond current complex network theory towards design or creation of living structures.

    1982-08-01

    The objective of the project was to produce and distribute a guide to commuting by bicycle in the Miami metropolitan area. The area is uniquely suited to bicycling because of its pleasant year-round climate and relatively flat topography. Persuading even a small percentage of automobile commuters to try biking to work could result in substantial energy savings in Miami as in most other major metropolitan areas. Seven of the largest employment centers in the area were selected as major commuter destinations suitable for bicycle commuters. Safe and scenic ways of commuting to these areas by bicycle were mapped and described in a series of short narratives. Additional material on safe riding techniques and the choice of equipment was developed. The resulting 40 page booklet, Biking to Work in Miami, was printed and distributed by the author to local cycling groups, bicycle interests, and others. Copies were also sent to interested parties outside the Miami area. The initial reception has been very encouraging and a number of favorable reply cards have been received with useful comments and suggestions. A revised version aimed at stimulating bikers to avail of the soon-to-be-opened rapid transit system is being considered. A writer for the Miami Herald is interested in using parts of the Guide for a series in the newspaper.

    Alexander (Andy) Franz Lubenow, Program Coordinator at the Space Telescope Science Institute, was diagnosed with cancer of the gallbladder, pancreas, and liver in May 2005 and died on 29 September 2005. He was forty-nine. Andy was born to Bodo and Helen Lubenow in St. Paul, Minnesota on 4 January 1956. In 1964 at the age of eight, he moved with his family to Buenos Aires, Argentina, and attended the American Community School there until returning with his family in 1973 to St. Paul. Argentina had a big impact on Andy's future as an astronomer. He later recalled how he had observed and was puzzled by the "upside-down" appearance of the Moon in the southern hemisphere. In Argentina, he built his first telescope using a mirror he had ground himself. He never parted ways with that instrument. Andy did not follow a standard educational track. He spent two years at St. Olaf College in Northfield, Minnesota, before transferring to the University of Minnesota, where he earned his bachelor's degree and began work towards a master's degree in astrophysics. Later he transferred to the University of Illinois at Urbana-Champaign, where he remained until Dr. Peter Stockman hired him to work on the Hubble Space Telescope project. While in school, he worked as a teacher's assistant, taught night school, and gave demonstrations of stargazing. He was an excellent teacher and had a flair for writing. He later wrote articles for a sailing magazine and a pilot's magazine. Andy was a very practical, meticulous, and steady worker, attributes that he combined with an understated and dry sense of humor. He was always able to find a way through a problem, no matter how sticky. If a job required him to roll up his sleeves and get it done through hard work, he would persevere. Nevertheless, he was always on the lookout for an easier way. He had no patience for being forced to deal with stupid things for stupid reasons. At work at the Space Telescope Science Institute (STScI), Andy was

  17. Alexander disease: a leukodystrophy caused by a mutation in GFAP.

    PubMed

    Johnson, Anne B

    2004-05-01

    Alexander disease, a rare fatal disorder of the central nervous system, causes progressive loss of motor and mental function. Until recently it was of unknown etiology, almost all cases were sporadic, and there was no effective treatment. It was most common in an infantile form, somewhat less so in a juvenile form, and was rarely seen in an adult-onset form. A number of investigators have now shown that almost all cases of Alexander disease have a dominant mutation in one allele of the gene for glial fibrillary acidic protein (GFAP) that causes replacement of one amino acid for another. Only in very rare cases of the adult-onset form is the mutation present in either parent. Thus, in almost all cases, the mutation arises as a spontaneous event, possibly in the germ cell of one parent.

    A preliminary report on the possible astronomical orientation of the Tomb of Alexander the Great, recently found and excavated by the greek archaeologist Liana Souvaltzi. The tomb is a greek building of doric style. Its enormous dimensions make it the largest amongst the found macedonian tombs (much bigger than the tomb of Philip II, Alexander's father). The tomb faces generally south---west and its orientation could be related either to the constellation of Centaurus or to the star Canopus. The walls of the two long sides of the building have strickingly different widhts. Moreover each wall has three doors (opposite in pairs) of slightly different sizes. We examine the possibility the openings of the doors and their assymetries to be designed and constructed according to some astronomical (solar or stellar) orientations.

    Glia play critical roles in maintaining the structure and function of the nervous system; however, the specific contribution that astroglia make to neurodegeneration in human disease states remains largely undefined. Here we use Alexander disease, a serious degenerative neurological disorder caused by astrocyte dysfunction, to identify glial-derived NO as a signalling molecule triggering astrocyte-mediated neuronal degeneration. We further find that NO acts through cGMP signalling in neurons to promote cell death. Glial cells themselves also degenerate, via the DNA damage response and p53. Our findings thus define a specific mechanism for glial-induced non-cell autonomous neuronal cell death, and identify a potential therapeutic target for reducing cellular toxicity in Alexander disease, and possibly other neurodegenerative disorders with glial dysfunction.

    Alexander's law states that the amplitude of the spontaneous nystagmus grows with increasing gaze in the direction of the fast phase. Using the search-coil method we employed head impulses at various eye-in-orbit azimuth angles to test (i) whether the normal vestibulo-ocular reflex (VOR) in the behaviorally relevant high-frequency range has intrinsic properties that could account for Alexander's law and (ii) whether such properties can also be shown in patients with unilateral vestibulopathy. We showed that the gain of the VOR remained unaffected by eye-in-orbit position in contols and in patients, both on ipsilesional and contralesional stimuli. These findings suggest that eye-in-orbit position does not directly modulate the activity in VOR pathways, neither during unbalanced but reciprocal (in controls), nor during unbalanced and nonreciprocal natural vestibular stimulation (in patients).

    Hinks, J. A.; Berg, J. A. van den; Donnelly, S. E.

    2011-03-15

    A transmission electron microscope (TEM) with in situ ion irradiation has been built at the University of Salford, U.K. The system consists of a Colutron G-2 ion source connected to a JEOL JEM-2000FX TEM via an in-house designed and constructed ion beam transport system. The ion source can deliver ion energies from 0.5 to 10 keV for singly charged ions and can be floated up to 100 kV to allow acceleration to higher energies. Ion species from H to Xe can be produced for the full range of energies allowing the investigation of implantation with light ions such as helium as well as the effects of displacing irradiation with heavy inert or self-ions. The ability to implant light ions at energies low enough such that they come to rest within the thickness of a TEM sample and to also irradiate with heavier species at energies sufficient to cause large numbers of atomic displacements makes this facility ideally suited to the study of materials for use in nuclear environments. TEM allows the internal microstructure of a sample to be imaged at the nanoscale. By irradiating in situ it is possible to observe the dynamic evolution of radiation damage which can occur during irradiation as a result of competing processes within the system being studied. Furthermore, experimental variables such as temperature can be controlled and maintained throughout both irradiation and observation. This combination of capabilities enables an understanding of the underlying atomistic processes to be gained and thus gives invaluable insights into the fundamental physics governing the response of materials to irradiation. Details of the design and specifications of the MIAMI facility are given along with examples of initial experimental results in silicon and silicon carbide.

The ingenuity of a titan of classical music, the Russian composer Alexander Scriabin (1872-1915), in combining all the sensory modalities into a polyphony of aesthetical experience, and his creation of a chord based on fourths rather than the conventional thirds are proposed as putative points of departure for insight, in future studies, into the neural processes that underlie the perception of beauty, individually or universally. Scriabin's "Omni-art" was a new synthesis of music, philosophy and religion, and a new aesthetic language, a unification of music, vision, olfaction, drama, poetry, dance, image, and conceptualization, all governed by logic, in the quest for the integrative action of the human mind toward a "higher reality" of which music is only a component.

  14. The 'horns' of a medical dilemma: Alexander the Great.

    PubMed

    Russell, Gül A

    2004-06-01

    Retrospective 'diagnosis' of clinical disorders of famous historical figures has been of medical interest. In the absence of a patient's 'body', the validity of 'physical symptoms' and their interpretation by contemporary diagnostic criteria are questionable. When the symptoms have been gleaned from the patients's effigy which, as in the case of Alexander the Great, is submerged in legend, the enterprise becomes inherently hazardous. In the present paper, some of the conceptual problems underlying retrospective diagnoses will be identified. Then the use of iconographic records, such as numismatics and sculpture, to provide evidence of clinical symptoms will be shown to be highly misleading.

    Alexander Disease (ALXDRD) is an autosomal dominant leukodystrophy caused by mutation in one allele of GFAP gene, encoding glial fibrillary acidic protein (GFAP). Most cases occur due to de novo. There are three clinical subtypes of ALXDRD: infantile, juvenile and adult form, but congenital form is also outlined. The disease's spectrum comprises of macrocephaly, progressive pyramidal signs, and seizures in congenital and infantile subtypes. Neuropathologically are enormous number of Rosenthal fibers (RF) mainly around vessels, in subependymal and subpial regions are found. The diagnosis is based on the typical findings on MRI: diffuse white mater lesions with frontal regions preponderance and possibly on the detection of the gene mutation. Here we present six Polish children affected of Alexander disease with congenital (1), infantile (4) and juvenile (1) form. Five of them were previously misdiagnosed as cerebral palsy or unspecific developmental delay; two patients had MRI because of another suspicion, before specific diagnosis was established. Molecular analysis performed in four cases confirmed mutations of GFAP gene; all mutation were de novo. The role of astroglia in brain is shortly reviewed. PMID:27442695

    Alexander the Great died in 323 B.C. from an unknown cause. Physical depictions of this historical figure reveal the likelihood of a cervical scoliotic deformity. This is substantiated with the medical history and is correlated with his untimely death. For the first time, it is concluded that Alexander's death may have ensued from the sequelae of congenital scoliotic syndrome.

  6. Obituary: Alexander (Andy) Franz Lubenow, 1956-2005

    Buie, Marc William

    2006-12-01

    Alexander (Andy) Franz Lubenow, Program Coordinator at the Space Telescope Science Institute, was diagnosed with cancer of the gallbladder, pancreas, and liver in May 2005 and died on 29 September 2005. He was forty-nine. Andy was born to Bodo and Helen Lubenow in St. Paul, Minnesota on 4 January 1956. In 1964 at the age of eight, he moved with his family to Buenos Aires, Argentina, and attended the American Community School there until returning with his family in 1973 to St. Paul. Argentina had a big impact on Andy's future as an astronomer. He later recalled how he had observed and was puzzled by the "upside-down" appearance of the Moon in the southern hemisphere. In Argentina, he built his first telescope using a mirror he had ground himself. He never parted ways with that instrument. Andy did not follow a standard educational track. He spent two years at St. Olaf College in Northfield, Minnesota, before transferring to the University of Minnesota, where he earned his bachelor's degree and began work towards a master's degree in astrophysics. Later he transferred to the University of Illinois at Urbana-Champaign, where he remained until Dr. Peter Stockman hired him to work on the Hubble Space Telescope project. While in school, he worked as a teacher's assistant, taught night school, and gave demonstrations of stargazing. He was an excellent teacher and had a flair for writing. He later wrote articles for a sailing magazine and a pilot's magazine. Andy was a very practical, meticulous, and steady worker, attributes that he combined with an understated and dry sense of humor. He was always able to find a way through a problem, no matter how sticky. If a job required him to roll up his sleeves and get it done through hard work, he would persevere. Nevertheless, he was always on the lookout for an easier way. He had no patience for being forced to deal with stupid things for stupid reasons. At work at the Space Telescope Science Institute (STScI), Andy was

  7. Miocene drowning of temperate (Foramol) carbonate platform: upper Miami Terrace

    SciTech Connect

    Carannante, G.; Simone, L.; Neumann, C.

    1986-05-01

    Oligocene neritic rocks dredged from 350 m on the upper Miami Terrace exhibit repeated phosphatization as well as a filled void system containing post-Burdigalian foraminifera. During drowning, a neritic hardground was subjected to both pelagic deposition (infills) and repeated marine exposure (borings, P-coatings, etc). The neritic grainstone-packstone contains large benthic foraminifera, red algae, bryozoans, pelecypods, ahermatypic corals, echinoids, and some planktonic foraminifera. This composition association is the Foramol type characteristic of temperate to subtropical neritic environments such as the present Mediterranean, Brazilian, and New Zealand shelves. These temperate sediments derive from the local biocoenose, and accumulate slowly in deep sheets of loose skeletal debris. They become relict seaward where they are often bored, corroded, stained, glauconitized, and cemented into hardgrounds. Locally, hemipelagic cover might produce a palimpsest sequence. Recent Foramol-type platforms are undergoing drowning. The Miami Terrace is compared to very similar Miocene Foramol-type platforms now exposed in the southern Apennines. Both are characterized by neritic sequences passing upward into hemipelagics, via a palimpsest interval marked by glauconitic, phosphatic, iron-stained grains often mineralized into hardgrounds. The drowning of the Miami Terrace hence coincided with and, the authors suppose, was a result of the shift from a rapid, oligotrophic, tropical accumulation to a slow, temperate, eutrophic carbonate accumulation caused in turn by a temporary paleo-oceanographic shift to cooler, richer, neritic conditions within the history of this now subtropical setting.

  8. Geophysical Investigation Along the Great Miami River From New Miami to Charles M. Bolton Well Field, Cincinnati, Ohio

    Sheets, R.A.; Dumouchelle, D.H.

    2009-01-01

    Three geophysical profiling methods were tested to help characterize subsurface materials at selected transects along the Great Miami River, in southwestern Ohio. The profiling methods used were continuous seismic profiling (CSP), continuous resistivity profiling (CRP), and continuous electromagnetic profiling (CEP). Data were collected with global positioning systems to spatially locate the data along the river. The depth and flow conditions of the Great Miami River limited the amount and quality of data that could be collected with the CSP and CRP methods. Data from the CSP were generally poor because shallow reflections (less than 5 meters) were mostly obscured by strong multiple reflections and deep reflections (greater than 5 meters) were sparse. However, modeling of CRP data indicated broad changes in subbottom geology, primarily below about 3 to 5 meters. Details for shallow electrical conductivity (resistivity) (less than 3 meters) were limited because of the 5-meter electrode spacing used for the surveys. For future studies of this type, a cable with 3-meter electrode spacing (or perhaps even 1-meter spacing) might best be used in similar environments to determine shallow electrical properties of the stream-bottom materials. CEP data were collected along the entire reach of the Great Miami River. The CRP and CEP data did not correlate well, but the CRP electrode spacing probably limited the correlation. Middle-frequency (3,510 hertz) and high-frequency (15,030 hertz) CEP data were correlated to water depth. Low-frequency (750 hertz) CEP data indicate shallow (less than 5-meter) changes in electrical conductivity. Given the variability in depth and flow conditions on a river such as the Great Miami, the CEP method worked better than either the CSP or CRP methods.

  9. Silurian Gastropoda from the Alexander terrane, southeast Alaska

    Gastropods are described from Ludlow-age strata of the Heceta Limestone on Prince of Wales Island, southeast Alaska. They are part of a diverse megabenthic fauna of the Alexander terrane, an accreted terrane of Siberian or Uralian affinities. Heceta Limestone gastropods with Uralian affinities include Kirkospira glacialis, which closely resembles "Pleurotomaria" lindstromi Oehlert of Chernyshev, 1893, Retispira cf. R. volgulica (Chernyshev, 1893), and Medfracaulus turriformis (Chernyshev, 1893). Medfracaulus and similar morphotypes such as Coelocaulus karlae are unknown from rocks that are unquestionably part of the North American continent (Laurentia) during Late Silurian time. Beraunia is previously known only from the Silurian of Bohemia. Pachystrophia has previously been reported only from western North American terranes (Eastern Klamath, York, and Farewell terranes) and Europe. Bathmopterus Kirk, 1928, is resurrected and is only known from the Silurian of southeast Alaska. Newly described taxa include Hecetastoma gehrelsi n. gen. and n. sp. and Baichtalia tongassensis n. gen. and n. sp. ??2008 The Geological Society of America.

  10. Alexander the Great's tombolos at Tyre and Alexandria, eastern Mediterranean

    NASA Astrophysics Data System (ADS)

    2008-08-01

    Tyre and Alexandria's coastlines are today characterised by wave-dominated tombolos, peculiar sand isthmuses that link former islands to the adjacent continent. Paradoxically, despite a long history of inquiry into spit and barrier formation, understanding of the dynamics and sedimentary history of tombolos over the Holocene timescale is poor. At Tyre and Alexandria we demonstrate that these rare coastal features are the heritage of a long history of natural morphodynamic forcing and human impacts. In 332 BC, following a protracted seven-month siege of the city, Alexander the Great's engineers cleverly exploited a shallow sublittoral sand bank to seize the island fortress; Tyre's causeway served as a prototype for Alexandria's Heptastadium built a few months later. We report stratigraphic and geomorphological data from the two sand spits, proposing a chronostratigraphic model of tombolo evolution.

  11. Teaching Nuclear Radiation and the Poisoning of Alexander Litvinenko

    2008-03-01

    The recent international story about the death of the former KGB agent Alexander Litvinenko has more than just a few wondering about radiation poisoning and the sinister sounding polonium-210. I was preparing to begin a nuclear radiation unit the Monday after Thanksgiving 2006. As it turned out, Litvinenko died Thanksgiving Day after a short and terrible three-week illness. Having the story continue to unfold throughout the next two weeks of the new unit provided a daily opportunity for students to see the relevance of what we were doing in class. My students were able to have meaningful and informed conversations with their peers and parents over an important international event. They even began to feel a bit like authorities themselves when listening to experts respond to media questions about polonium-210 and nuclear radiation in general. This paper discusses some of the ways that the story of Litvinenko was used while presenting the topic of nuclear radiation.

    This study presents an in-depth analysis of Alexander von Humboldt's descriptions and critical comments on the colonial society of the different regions he visited during his well-known expedition through the Americas (1799-1804). The criticisms of colonialism that he expressed, reflecting his personal convictions, have already been the focal point of many studies, but Humboldt also was able to offer a more differentiated assessment through comparisons of regional and local traditions and developments. This essay focuses on his personal diaries, which offer many interesting comments on colonial societies. These considerations and impressions made during the expedition are of particular scholarly value since they were not subject to censorship of any kind. PMID:19852391

    Heightened fall risk, potentially caused by aging-related changes in gait, is a serious health issue faced by older adults. The Alexander Technique is thought to improve balance and motor function; however, the technique's effect on gait has not been studied. The purpose of this study was to examine the effect of Alexander Technique training in older adults on the temporospatial characteristics of gait and medio-lateral center of mass displacement during fast and comfortably paced over-ground walking. Six licensed Alexander Technique teachers and seven controls between the ages of 60 and 75 years of age participated in the study. Alexander Technique teachers exhibited a reduction in medio-lateral center of mass displacement during fast paced walking compared to comfortably paced walking that was not present in controls. Due to this difference Alexander Technique teachers displayed a smaller medio-lateral Center of Mass displacement compared to controls during fast paced walking. Alexander Technique teachers also demonstrated significantly smaller stride width and lower gait timing variability compared to controls. These findings, which suggest superior control of dynamic stability during gait and potentially reduced fall risk in Alexander Technique teachers, warrant further study.

    This report contains the major findings of a 1999?2001 assessment of water quality in the Great and Little Miami River Basins. It is one of a series of reports by the National Water-Quality Assessment (NAWQA) Program that present major findings in 51 major river basins and aquifer systems across the Nation. In these reports, water quality is discussed in terms of local, State, and regional issues. Conditions in a particular basin or aquifer system are compared to conditions found elsewhere and to selected national benchmarks, such as those for drinking-water quality and the protection of aquatic organisms. This report is intended for individuals working with water-resource issues in Federal, State, or local agencies, universities, public interest groups, or in the private sector. The information will be useful in addressing a number of current issues, such as the effects of agricultural and urban land use on water quality, human health, drinking water, source-water protection, hypoxia and excessive growth of algae and plants, pesticide registration, and monitoring and sampling strategies. This report is also for individuals who wish to know more about the quality of streams and ground water in areas near where they live and how that water quality compares to the quality of water in other areas across the Nation. The water-quality conditions in the Great and Little Miami River Basins summarized in this report are discussed in detail in other reports that can be accessed from (http://oh.water.usgs.gov/miam/intro.html). Detailed technical information, data and analyses, collection and analytical methodology, models, graphs, and maps that support the findings presented in this report, in addition to reports in this series from other basins, can be accessed from the national NAWQA Web site (http://water.usgs.gov/nawqa).

  16. The modern mythology of the left-handedness of Alexander the Great.

    PubMed

    McManus, I C

    2006-11-01

    The prevalent modern suggestion that Alexander the Great was left-handed probably derives from Michael Barsley's (1966) book, Left-handed man is a right-handed word, perhaps by mutation from as earlier story cited by Wile in 1934 from a 17th century Rabbirical exegesis, which said that Alexander discovered a country where all the inhabitants were left-handed. That itself may derive in part from the medieval Hebrew Book of Jossippon, which mentions Alexander talking of the superiority of the left hand and of how "kings stemming from the tribe of kings are left-handed".

    Yost, William P.

    1995-01-01

    Hydrogeologic data were collected in September, October, and November 1993 to define the ground-water levels and the ground-water/surface-water relations in the vicinity of Dayton, Ohio. In this report, water levels are listed for 678 wells completed in sand and gravel. Data from 101 streamflow measurements made at selected sites along the Great Miami, Stillwater, Mad, and Little Miami Rivers and their tributaries during 2-day gain-loss study also are listed. Surface-water altitudes were determined at 11 stream-gaging stations and 39 other streamflow measurement sites. Discharge data for measurements made at 30 storm-sewer outfalls are given. Streamflow and discharge data obtained during the study were used to calculate the gain or loss of streamflow along 16 selected reaches of the Great Miami, Stillwater, Mad, and Little Miami Rivers. Streambed-conductivity data obtained by use of seepage meters at nine different sites also are given.

  13. The efficacy of medicine during the campaigns of Alexander the Great.

    PubMed

    Ruffin, J R

    1992-09-01

    This paper examines the various factors that may have determined the efficacy of physicians during the campaigns of Alexander the Great. Such general variables as the adequacy of preparation, the nature of the medical profession, and the extent of preventative measures are all discussed at the outset of the paper, followed by a more detailed examination of the specific wounds, illnesses, and treatments of Alexander as described in the accounts of the Alexander historians Plutarch, Curtius, and Arrian. Where no remedy is given by these writers (as is usually the case), this paper speculates on the efficacy of possible treatments as advocated in the contemporary Hippocratic corpus. Casualty statistics of the campaigns are compared to a similar review of Homer's Iliad. From these examinations, this paper concludes that wound treatment efficacy was significantly greater than that of illness treatment, and that Alexander lost many more men to disease than to the wounds of war.

  14. The Berlin tradition in Chicago: Franz Alexander and the Chicago Institute for Psychoanalysis.

    PubMed

    Schmidt, Erika S

    2010-01-01

    Freud considered Franz Alexander, the first graduate of the Berlin Psychoanalytic Institute and an assistant in the Berlin Polyclinic, to be "one of our strongest hopes for the future." Alexander went on to become the first director of the Chicago Institute for Psychoanalysis in 1932 and modeled some of the Chicago Institute's mission on his Berlin experiences. He was also a researcher in psychosomatic medicine, a prolific writer about psychoanalysis and prominent in psychoanalytic organizations. As he proposed modifications in psychoanalytic technique, he became a controversial figure, especially in the elaboration of his ideas about brief therapy and the corrective emotional experience. This paper puts Alexander's achievements in historical context, draws connections between the Berlin and Chicago Institutes and suggests that, despite his quarrels with traditional psychoanalysis, Alexander's legacy may be in his attitude towards psychoanalysis, characterized by a commitment to scientific study, a willingness to experiment, and a conviction about the role of psychoanalysis within the larger culture.

    John Alexander Lindsay was born at Fintona, county Tyrone in 1856, and at the age of 23 he graduated in medicine at the Royal University of Ireland. After two years in London and Europe he returned to Belfast to join the staff at the Royal Victoria Hospital and in 1899 he was appointed to the professorship of medicine. He was valued by the students for his clarity and by his colleagues for his many extracurricular contributions to the medical profession in the positions entrusted to him. He published monographs on Diseases of the Lungs, and the Climatic Treatment of Consumption, but his later Medical Axioms show his deep appreciation of studied clinical observation. Although practice was changing in the new century Lindsay displayed an ability to change with the new requirements, as evidenced by his lecture on electrocardiography as president of the section of medicine of the Royal Academy of Medicine in Ireland in 1915. He was impressed by the way the string galvanometer changed attention from stenosis and incompetence of the valves to the cardiac musculature, but rightly suspected that there was more to be told about the state of the myocardium than Einthoven's three leads revealed. His death occurred in Belfast in 1931.

    Bioengineering/Biomedical Engineering is considered amongst the most reputable fields within the global arena, and will likely be the primer for any future breakthroughs in Medicine and Biology. Bioengineering/biomedical engineering education has evolved since late 1950s and is undergoing advancement in leading academic institutions worldwide. This paper delineates an original study on the world proliferation of bioengineering/biomedical engineering education and bears the name 'Project Alexander the Great'. The initial step of the project was to survey all 10448 universities, recognized by the International Association of Universities, spread among the 193 member states of the United Nations within the six continents. The project aims at identifying, disseminating, and networking, through the world-wide-web, those institutions of higher learning that provide bioengineering/biomedical engineering education. The significance of this project is multifold: i) the inception of a web-based 'world-map' in bioengineering/biomedical engineering education for the potential international student desiring to pursue a career in this field; ii) the global networking of bioengineering/biomedical engineering academic/research programs; iii) the promotion of first-class bioengineering/biomedical engineering education and the catalysis of global proliferation of this field; iv) the erection of bridges among educational institutions, industry, and professional societies or organizations involved in Bioengineering/Biomedical Engineering; and v) the catalysis in the establishment of framework agreements for cooperation among the identified institutions offering curricula in this field. This paper presents the results obtained from Africa and North America. The whole project is due to be completed by 2009.

  20. Cyclicity in Silurian island-arc carbonates, Alexander terrane, Alaska

    SciTech Connect

    1993-03-01

    Silurian carbonates from Alaska (Alexander terrane) record the evolution of a submarine platform during waning volcanism in an island arc. A detailed stratigraphic analysis of a 47 meter-thick sequence revealed the existence of cyclically repeated limestones: coral-stromatoporoid wackestones alternate with oncoid packstones and bioturbated, silty lime mudstones. The coral-stromatoporoid deposits are characterized by a low-diversity assemblage of dendroid corals, massive stromatoporoids, Atrypoidea brachiopods, and rare occurrences of biostromes associated with Solenopora, high-spired gastropods, and crinoids. Oncoids typically are 2-6 mm in diameter and form massive, meter-thick units. Coated grains are symmetrically developed, have a shell or algal nucleus, and are also a minor component of coral-stromatoporoid beds. These lithologic units form seven, shallowing-upwards cycles (parasequences) that range in thickness from 3-9 meters. Coral-stomatoporoid wackestones form the base of each cycle and grade upwards into oncoid packstones with silty, lime mudstones at the top. This succession of lithofacies within each cycle reflects an increase in energy levels from relatively deeper water environments to relatively shallower ones. The lack of abrasion in the corals and stromatoporoids suggests predominantly quiet-water conditions in shallow subtidal areas affected by periodic turbulence. Comparison with correlative sections in Alaska and lack of correspondence with global sea level curves suggest that the primary cause of cyclicity was tectonic perturbations with secondary eustatic effects. Cyclic deposition in peri/subtidal sites was terminated by rapid drowning of the carbonate platform during late Silurian orogenesis.

  1. The life and death of Alexander Bogdanov, physician.

    PubMed

    Huestis, D W

    1996-08-01

    It was early in April in 1928 when the word went out in Moscow that Alexander Bogdanov had died. He was a controversial figure, an old Bolshevik who had left that party long before the 1917 revolution and never returned. All the same, he had had Lenin's respect as a scientist (as long as he stayed out of politics). More recently, he also had the support of the new party strong man, Stalin. Bogdanov opposed the growing despotism of the "dictatorship of the proletariat", under which slogan Communist autocracy was being developed. But he was respected as a tireless propagandist for the socialist cause, an enthusiastic teacher of the proletariat, and a writer of arcane science and philosophy. Bogdanov was held in such respect that Communist bigwigs spoke glowingly at the funeral, praising his intellect, courage, and dedication to science and humanity. They did not fail to point out that he had split with his one-time friend, Lenin, and had succumbed to ideological "errors". Indeed, he had powerful enemies in the early Soviet state. Bogdanov was a physician, economist, philosopher, natural scientist, writer of utopian science fiction, poet, teacher, politician (unsuccesful), lifelong revolutionary, forerunner of what we now call cybernetics and organizational science, and founder of the world's first institution devoted entirely to the field of blood transfusion. You could call him a Renaissance man. Although he clearly fitted the category of the late-nineteenth-century Russian intellectual revolutionary, Bogdanov differed from most of them in being no dilettante. More than just a theorist, he was an active scientist and physician. As a teacher, he firmly believed that education and indoctrination could alter people's ways of thinking and behaving, and that humanity could be perfected under socialism. Like many revolutionaries, Bogdanov tried to keep ahead of the Tsar's police by using a variety of pseudonyms, among them Riadavoy, Werner, Maximov, and Bogdanov. After

    We investigate tropical cyclone wind and storm surge damage reduction for five areas along the Miami-Dade County coastline either by hardening buildings or by the hypothetical application of wind-wave pumps to modify storms. We calculate surge height and wind speed as functions of return period and sea surface temperature reduction by wind-wave pumps. We then estimate costs and economic losses with the FEMA HAZUS-MH MR3 damage model and census data on property at risk. All areas experience more surge damages for short return periods, and more wind damages for long periods. The return period at which the dominating hazard component switches depends on location. We also calculate the seasonal expected fraction of control damage for different scenarios to reduce damages. Surge damages are best reduced through a surge barrier. Wind damages are best reduced by a portfolio of techniques that, assuming they work and are correctly deployed, include wind-wave pumps.

    During the second half of the 1980s, Miami had a syphilis epidemic while gonorrhea rates decreased. To determine whether the direction of these trends truly differed within all population subgroups or whether they resulted from aggregating groups within which trends were similar, records from four sexually transmitted disease clinics from 1986 to 1990 and census data from 1990 were used to compare race-, sex-, age-, and zip code-specific groups. Syphilis and gonorrhea clustering was similar; 50% of cases occurred in the same zip codes, representing 10% of the population. In all groups, gonorrhea decreased (aggregate 48%) while syphilis first increased (aggregate 47%) and then decreased. Determining reasons for these different trends may facilitate controlling these diseases.

    2011-02-01

    Traditionally, forms of body work such as Alexander Technique have been excluded from mainstream biomedicine and healthcare, despite attempts by practitioners to have the work accepted within the medical community. Using data from a UK-based study of Alexander Technique which combined participant observation, interviews with 17 teachers and pupils, and analysis of historical texts, this article examines the relationship of the Alexander Technique to the field of healthcare, looking at its embodied practices, and contrasting these with the discourses in which it is framed. Applying Foucault's concept of 'techniques of the self', the article examines Alexander Technique's physical practices as a form of embodied knowledge, and goes on to look at its use of particular ideas about nature and evolution as guiding authorities, its emphasis on holism through its conception of the 'self', and how it has been positioned in relation to biomedical approaches. The article argues that while the embodied practice of Alexander Technique has much to offer to mainstream healthcare, the discourses and knowledge systems in which it is embedded make it unlikely to receive mainstream medical acceptance.

    Annual losses from tropical cyclones (TCs) in the United States are estimated to average about $10-billion/year. Damages can be caused by wind, storm surge, and floods. Some U.S. coastal areas experience high TC wind speeds and contain geophysical features vulnerable to storm surges and flooding. Since the Miami-Dade County coastline contains a range of topography, bathymetry and infrastructure with different susceptibilities to TCs, optimal policy choices regarding methods to reduce TC damages depend strongly on locale. Various adaptation techniques, including "hardening", are available to reduce damages from TCs. Strategies to reduce the intensity of a TC, while still hypothetical, offer a very different approach to reducing damages. Here we investigate tropical cyclone wind and storm surge damage reduction for five areas along the Miami-Dade County coastline either by hardening buildings or by the hypothetical application of wind-wave pumps to modify storms. We calculate surge height and wind speed as functions of return period and sea surface temperature reduction by wind-wave pumps. We then estimate costs and economic losses with the FEMA HAZUS-MH MR3 damage model and census data on property at risk. All areas experience more surge damages for short return periods, and more wind damages for long periods. The return period at which the dominating hazard component switches depends on location.

    This historical article describes the life and work of the British physician Samuel Alexander Kinnier Wilson (1878-1937), who was one of the world's greatest neurologists of the first half of the 20th century. Early in his career, Wilson spent one year in Paris in 1903 where he learned from Pierre-Marie at Bicêtre Hospital. He subsequently retained uninterrupted links with French neurology. He also visited in Leipzig the German anatomist Paul Flechsig. In 1904, Wilson returned to London, where he worked for the rest of his life at the National Hospital for the Paralysed and Epileptic (later the National Hospital for Nervous Diseases, and today the National Hospital for Neurology and Neurosurgery) in Queen Square, and also at Kings' College Hospital. He wrote on 'the old motor system and the new', on disorders of motility and muscle tone, on the epilepsies, on aphasia, apraxia, tics, and pathologic laughing and crying, and most importantly on Wilson's disease. The other objective of our paper is to commemorate the centenary of Wilson's most important work published in 1912 in Brain, and also in Revue Neurologique, on an illness newly recognized and characterized by him entitled "Progressive lenticular degeneration, a familial nervous disease associated with liver cirrhosis". He analyzed 12 clinical cases, four of whom he followed himself, but also four cases previously published by others and a further two that he considered in retrospect had the same disease as he was describing. The pathological profile combined necrotic damage in the lenticular nuclei of the brain and hepatic cirrhosis. This major original work is summarized and discussed in the present paper. Wilson not only delineated what was later called hepato-lenticular degeneration and Wilson's disease, but also introduced for the first time the terms extrapyramidal syndrome and extrapyramidal system, stressing the role of the basal ganglia in motility. The present historical work emphasizes the special

    The medical response to radiation--whether the result of radiological warfare, terrorist deployment of improvised radiation dispersal weapons, political assassination, occupational or industrial accidents or the medically radiated patient remains one of the least taught among all disciplines within medical education. In the aftermath of 9/11 among medical vulnerabilities to toxicant threats, of all the categories of weapons of mass destruction (WMD)--whether using the CBRNE (chemical, biological, radiological, nuclear, explosive) or NBC (nuclear, biological, chemical) acronym--radiation is the least taught in professional schools, responder cultures or civil preparedness organizations. To date, few health care professionals (HCP) possess the fundamental knowledge or skills to identify and diagnose, let alone treat a radiation victim; this vulnerability made even more obvious in the aftermath of the high profile assassination of former Russian agent Alexander Litvinenko. He was poisoned with Polonium210. Radioactive substances are ubiquitous with radiation sources being in or transported through virtually every region nationwide. It is essential to increase preparedness among community and rural health care facilities as well as urban and university hospitals. Managing radiation injuries effectively requires access to specialized equipment and expertise. Radiation sickness is progressive and may require acute, critical and long-term care throughout the course of illness. Regardless of the source, preparedness rests upon acknowledging a threat exists and dedicating the resources to address the risks including the enhancement of training and equipment. Mass or individual exposures to radiation present unique challenges to the entire response continuum from law enforcement, first responders and emergency medical care. Increased education about and practice in responding to radiological threats is essential to enhance preparedness.

    The 19th century witnessed a resurgence of interest in Earth's magnetic field. Both observational and theoretical aspects were involved, and one of the emblematic figures of this period was Alexander von Humboldt. Throughout a long life he maintained a strong interest in a broad area of subjects, however, here we are interested in his role in geomagnetism, and particularly in his pioneering contributions to charting the geomagnetic field. Alexander von Humboldt efforts in measuring and charting the Earth's magnetic field are recounted and the maps of declination, inclination and total intensity he had prepared are compared, favorably, with maps for the same epoch based on a modern model of the geomagnetic field, gufm1. This modern assessment of the accuracy of von Humboldt's geomagnetic charts illustrates the importance of his work, being also our homage to the 150th anniversary of the death of Alexander von Humboldt.

    In Memoriam of Alexander A Golovin (1962-2008) Alexander (Sasha) Golovin passed away on 10 September 2008. Sasha's scientific heritage includes seminal works in different fields of physics, from Marangoni convection to self-assembly of quantum dots, and from combustion fronts to anomalous diffusion in flows and on a crystal surface. A graduate of the Moscow Institute for Physics and Technology, he had very broad scientific interests and a unique ability to identify and solve new, intellectually challenging and technologically important problems. One of the basic fields of Sasha's research was the fluid dynamics in systems with interfaces. His favorite subject was the motion of droplets, bubbles and particles in the presence of heat and mass transfer. Sasha's early works contained the discovery of the spontaneous motion of droplets due to the Marangoni effect and the investigation of the interaction between solid particles, bubbles and droplets caused by the Marangoni effect, which is a crucial factor that determines the effect of heat/mass transfer on the rate of coalescence. In both cases, Sasha's work was the first in a long sequence of papers written by different authors. Later, Sasha returned to that field when studying such fascinating subjects as levitation of droplets above the surface of an evaporating liquid and encapsulation of particles and bubbles by an advancing solidification front. The subject of interfacial hydrodynamics overlaps with another basic field of Sasha's research, the theory of pattern formation. The contribution of Sasha's work to the modern understanding of the variety of pattern formation phenomena is significant. It includes the analysis of the interaction between long-wave and short-wave instability modes in Marangoni convection, investigation of the large-scale Marangoni convection that led to the prediction of different patterns including quasipatterns, and the description of various non-potential effects in Marangoni convection

  20. Holocene morphogenesis of Alexander the Great's isthmus at Tyre in Lebanon

    In 332 B.C., Alexander the Great constructed an ≈1,000-m-long causeway to seize the offshore island of Tyre. The logistics behind this engineering feat have long troubled archaeologists. Using the Holocene sedimentary record, we demonstrate that Alexander's engineers cleverly exploited a shallow proto-tombolo, or sublittoral sand spit, to breach the offshore city's defensive impregnability. We elucidate a three-phase geomorphological model for the spit's evolution. Settled since the Bronze Age, the area's geological record manifests a long history of natural and anthropogenic forcings. (i) Leeward of the island breakwater, the maximum flooding surface (e.g., drowning of the subaerial land surfaces by seawater) is dated ≈8000 B.P. Fine-grained sediments and brackish and marine-lagoonal faunas translate shallow, low-energy water bodies at this time. Shelter was afforded by Tyre's elongated sandstone reefs, which acted as a 6-km natural breakwater. (ii) By 6000 B.P., sea-level rise had reduced the dimensions of the island from 6 to 4 km. The leeward wave shadow generated by this island, allied with high sediment supply after 3000 B.P., culminated in a natural wave-dominated proto-tombolo within 1-2 m of mean sea level by the time of Alexander the Great (4th century B.C.). (iii) After 332 B.C., construction of Alexander's causeway entrained a complete anthropogenic metamorphosis of the Tyrian coastal system.

  6. Identification of metapopulation dynamics among Northern Goshawks of the Alexander Archipelago, Alaska, and Coastal British Columbia

    Northern Goshawks occupying the Alexander Archipelago, Alaska, and coastal British Columbia nest primarily in old-growth and mature forest, which results in spatial heterogeneity in the distribution of individuals across the landscape. We used microsatellite and mitochondrial data to infer genetic structure, gene flow, and fluctuations in population demography through evolutionary time. Patterns in the genetic signatures were used to assess predictions associated with the three population models: panmixia, metapopulation, and isolated populations. Population genetic structure was observed along with asymmetry in gene flow estimates that changed directionality at different temporal scales, consistent with metapopulation model predictions. Therefore, Northern Goshawk assemblages located in the Alexander Archipelago and coastal British Columbia interact through a metapopulation framework, though they may not fit the classic model of a metapopulation. Long-term population sources (coastal mainland British Columbia) and sinks (Revillagigedo and Vancouver islands) were identified. However, there was no trend through evolutionary time in the directionality of dispersal among the remaining assemblages, suggestive of a rescue-effect dynamic. Admiralty, Douglas, and Chichagof island complex appears to be an evolutionarily recent source population in the Alexander Archipelago. In addition, Kupreanof island complex and Kispiox Forest District populations have high dispersal rates to populations in close geographic proximity and potentially serve as local source populations. Metapopulation dynamics occurring in the Alexander Archipelago and coastal British Columbia by Northern Goshawks highlight the importance of both occupied and unoccupied habitats to long-term population persistence of goshawks in this region.

  2. Urban Evapotranspiration and Carbon Dioxide Flux in Miami - Dade, Florida

    NASA Astrophysics Data System (ADS)

    2010-12-01

    Atmospheric Carbon Dioxide (CO2) concentrations are leading indicators of secular climate change. With increasing awareness of the consequences of climate change, methods for monitoring this change are becoming more important daily. Of particular interest is the carbon dioxide exchange between natural and urban landscapes and the correlation of atmospheric CO2 concentrations. Monitoring Evapotranspiration (ET) is important for assessments of water availability for growing populations. ET is surprisingly understudied in the hydrologic cycle considering ET removes as much as 80 to over 100% of precipitation back into the atmosphere as water vapor. Lack of understanding in spatial and temporal ET estimates can limit the credibility of hydrologic water budgets designed to promote sustainable water use and resolve water-use conflicts. Eddy covariance (EC) methods are commonly used to estimate ET and CO2 fluxes. The EC platform consist of a (CSAT) 3-D Sonic Anemometer and a Li-Cor Open Path CO2/ H2O Analyzer. Measurements collected at 10 Hz create a very large data sets. A EC flux tower located in the Snapper Creek Well Field as part of a study to estimate ET for the Miami Dade County Water and Sewer project. Data has been collected from December 17, 2009 to August 30, 2010. QA/QC is performed with the EdiRe data processing software according to Ameri-flux protocols. ET estimates along with other data--latent-heat flux, sensible-heat flux, rainfall, air temperature, wind speed and direction, solar irradiance, net radiation, soil-heat flux and relative humidity--can be used to aid in the development of water management policies and regulations. Currently, many financial institutions have adopted an understanding about baseline environmental monitoring. The “Equator Principle” is an example of a voluntary standard for managing social and environmental risk in project financing and has changed the way in which projects are financed.

  6. Protein misfolding and oxidative stress promote glial-mediated neurodegeneration in an Alexander disease model

    2011-01-01

    Although alterations in glial structure and function commonly accompany death of neurons in neurodegenerative diseases, the role glia play in modulating neuronal loss is poorly understood. We have created a model of Alexander disease in Drosophila by expressing disease-linked mutant versions of glial fibrillary acidic protein (GFAP) in fly glia. We find aggregation of mutant human GFAP into inclusions bearing the hallmarks of authentic Rosenthal fibers. We also observe significant toxicity of mutant human GFAP to glia, which is mediated by protein aggregation and oxidative stress. Both protein aggregation and oxidative stress contribute to activation of a robust autophagic response in glia. Toxicity of mutant GFAP to glial cells induces a non-cell autonomous stress response and subsequent apoptosis in neurons, which is dependent on glial glutamate transport. Our findings thus establish a simple genetic model of Alexander disease and further identify cellular pathways critical for glial-induced neurodegeneration. PMID:21414908

This article shows how clinical experience is used in Alexander’s works by concentrating on his therapeutic advice on epilepsy and, in particular, on pharmacology and the group of so-called natural remedies. I argue that clinical testing is used not only for the introduction of new medicines but also as an instrument for checking the therapeutic effect of popular healing practices. On another level, this article discusses Alexander’s role as the author of a medical compendium; it suggests that by marking the cases of clinical testing with a set of recurrent expressions, Alexander leads his audience to reflect on his medical authority and personal contribution.

    Alexander von Lichtenberg (1880-1949) was one of the famous members of the German Urological Society (DGU) in pre-war Germany. He introduced excretion urography and a special TURP Instrument. In 1928 he was president of the 8th meeting held in the German capital Berlin. His Handbook of Urology, released by Ferdinand Springer publishing house, was a trendsetter in establishing urology as a specialty in Germany and bringing together the whole wisdom of all aspects of urology. He was the founder of the famous Maximilian Nitze Award of the DGU. As a Jew he-like many others-was forced to leave Nazi Germany after 1933. Even in Hungary, his native country, he again had to resist anti-Semitic hostility. Later on he lived in Mexico. Alexander von Lichtenberg has to be remembered with special focus on the exodus of German Jewish scientists during the Nazi time.

    A quartz monzonite-syenite-alkali granite plutonic complex in eastern Alaska crosscuts the contact of the Alexander terrane and Wrangellia and intrudes the basement rocks of both terranes. Zircon U-Pb data indicate an intrusion age of 309 {plus minus} 5 Ma (Middle Pennsylvanian) for the pluton, and {sup 40}K-{sup 40}Ar age for hornblende separates indicate cooling to about 450 C during Middle Pennsylvanian-Early Permian time. The new field relations and age data demonstrate the Wrangellia and the Alexander terrane were contiguous during the Middle Pennsylvanian. This conclusion provides an important new constraint on paleogeographic reconstructions of the northwest Cordillera, and necessitates reassessment of stratigraphic and paleomagnetic data that were cited as evidence that the terranes evolved separately until the late Mesozoic.

    Paleozoic limestone, graywacke, sandstone, milestone, red beds and volcanic rocks of the Alexander terrane, southeastern Alaska, have yielded six paleomagnetic pole positions after thermal and alternating-field demagnetization. These poles are from sample groups of late Middle Ordovician, Late Ordovician, Devonian, Late Devonian, and early and late Carboniferous age. To test various tectonic models for the structural development of this part of western North America, the paleomagnetic results are compared to those for the North American craton. It is found that the observed inclination and declination values deviate significantly from the values predicted for the present-day position of the Alexander terrane (55.5N, 133.5W). Better matching can be obtained for a paleoposition of the terrane at about 40N, 120W, in the present position of western Nevada and northeastern California. In addition, an in situ 25° clockwise rotation of the terrane is required to restore it to its original position.

We present evidence that this should be considered as a differential diagnosis and how it might explain an unusual symptom seen at his deathbed in Babylon six years later.

    Alexander disease is a fatal neurodegenerative disease caused by mutations in the astrocyte intermediate filament glial fibrillary acidic protein (GFAP). The disease is characterized by elevated levels of GFAP and the formation of protein aggregates, known as Rosenthal fibers, within astrocytes. Lithium has previously been shown to decrease protein aggregates by increasing the autophagy pathway for protein degradation. In addition, lithium has also been reported to decrease activation of the transcription factor STAT3, which is a regulator of GFAP transcription and astrogliogenesis. Here we tested whether lithium treatment would decrease levels of GFAP in a mouse model of Alexander disease. Mice with the Gfap-R236H point mutation were fed lithium food pellets for 4 to 8 weeks. Four weeks of treatment with LiCl at 0.5% in food pellets decreased GFAP protein and transcripts in several brain regions, although with mild side effects and some mortality. Extending the duration of treatment to 8 weeks resulted in higher mortality, and again with a decrease in GFAP in the surviving animals. Indicators of autophagy, such as LC3, were not increased, suggesting that lithium may decrease levels of GFAP through other pathways. Lithium reduced the levels of phosphorylated STAT3, suggesting this as one pathway mediating the effects on GFAP. In conclusion, lithium has the potential to decrease GFAP levels in Alexander disease, but with a narrow therapeutic window separating efficacy and toxicity.

  17. Compressibility effects in the Miami isopycnic coordinate ocean model

    NASA Astrophysics Data System (ADS)

    Sun, Shan

    Potential density referenced to sea level pressure (sigmasb0) has shown its usefulness as vertical coordinate in ocean models in many ways, but there are problems with sigmasb0 (potential density referenced to sea level) coordinates in the deep ocean: sigmasb0(z) can be multivalued, leading to coordinate folding, and sigmasb0 surfaces can deviate from the so-called neutral surfaces, which are the surfaces along which turbulent lateral mixing takes place in a stratified medium. The reason for both of these problems is that most isopycnal models regard seawater as uniformly compressible. However, the effect of water temperature on compressibility cannot be ignored. In this study a two-pronged approach is taken to improve the model accuracy. First, since the effects of compressibility variation are proportional to the difference between the local and the reference pressure, we replace the model's traditional sigmasb0 coordinate by sigmasb2 (potential density referenced to 2000 dbar). This step eliminates many of the coordinate folding problems associated with sigmasb0 and generally reduces the difference between coordinate and neutrally buoyant surfaces. Second, we split the compressibility coefficient into a pressure- and a temperature-dependent part and, recognizing that the former is dynamically passive, retain only the effect of the latter in the governing equations. This is accomplished by introducing a new variable called "active density"-the density with the pressure-related compressibility removed. Therefore, sigmasb2 is adopted as vertical coordinate, but active density is used to express the seawater density within the layers. The above changes are applied in a near-global, 16-layer, 2sp° x 2sp°cos (lat.) Miami Isopycnic Coordinate Ocean Model (MICOM). The model is driven by observed atmospheric conditions. MICOM modified in this fashion produces realistic meridional mass and associated heat fluxes in the three major ocean basins. A realistic formation

  11. Recruiting a Diverse Set of Future Geoscientists through Outreach to Middle and High School Students and Teachers in Miami, Florida

    NASA Astrophysics Data System (ADS)

    Whitman, D.; Hickey-Vargas, R.; Draper, G.; Rego, R.; Gebelein, J.

    2014-12-01

    Florida International University (FIU), the State University of Florida in Miami is a large enrollment, federally recognized Minority Serving Institution with over 70% of the undergraduate population coming from groups underrepresented in the geoscience workforce. Recruiting local students into the geosciences is challenging because geology is not well integrated into the local school curriculum, the geology is poorly exposed in the low-relief south Florida region and many first generation college students are reluctant to enter unfamiliar fields. We describe and present preliminary findings from Growing Community Roots for the Geosciences in Miami, FL, a 2-year, NSF funded project run by the Department of Earth and Environment at FIU which aims to inform students enrolled in the local middle and high schools to educational and career opportunities in the geosciences. The project takes a multi-faceted approach which includes direct outreach through social media platforms and school visits, a 1-week workshop for middle school teachers and a 2-week summer camp aimed at high school students. An outreach team of undergraduate geoscience majors were recruited to build and maintain informational resources on Facebook, Instagram, Twitter and Google Plus and to accompany FIU faculty on visits to local middle schools and high schools. Both the teacher workshop and the summer camp included lectures on geoscience careers, fundamental concepts of solid earth and atmospheric science, hands on exercises with earth materials, fossils and microscopy, exercises with Google Earth imagery and GIS, and field trips to local geological sites and government facilities. Participants were surveyed at the beginning of the programs on their general educational background in math and science and their general attitudes of and interest in geoscience careers. Post program surveys showed significant increases in the comfort of teaching topics in geoscience among teachers and an increased

    Gargus, Gerald Vincent

    This investigation represents an in-depth understanding of teacher professional development at the Alexander Science Center School, a dependent charter museum school established through a partnership between the California Science Center and Los Angeles Unified School District. Three methods of data collection were used. A survey was distributed and collected from the school's teachers, resulting in a prioritized list of teacher professional development needs, as well as a summary of teachers' opinions about the school's existing professional development program. In addition, six key stakeholders in the school's professional development program were interviewed for the study. Finally, documents related to the school's professional development program were analyzed. Data collected from the interviews and documents were used to develop an understand various components of the Alexander Science Center School's professional development program. Teachers identified seven areas that had a high-priority for future professional development including developing skills far working with below-grade-level students, improving the analytical skills of student in mathematics, working with English Language Learners, improving students' overall reading ability levels, developing teachers' content-area knowledge for science, integrating science across the curriculum, and incorporating hands-on activity-based learning strategies to teach science. Professional development needs identified by Alexander Science Center School teachers were categorized based on their focus on content knowledge, pedagogical content knowledge, or curricular knowledge. Analysis of data collected through interviews and documents revealed that the Alexander Science Center School's professional development program consisted of six venues for providing professional development for teachers including weekly "banked time" sessions taking place within the standard school day, grade-level meetings, teacher support

  13. Nitrogen and phosphorus in streams of the Great Miami River Basin, Ohio, 1998-2000

    Reutter, David C.

    2003-01-01

    Sources and loads of nitrogen and phosphorus in streams of the Great Miami River Basin were evaluated as part of the National Water-Quality Assessment program. Water samples were collected by the U.S. Geological Survey from October 1998 through September 2000 (water years 1999 and 2000) at five locations in Ohio on a routine schedule and additionally during selected high streamflows. Stillwater River near Union, Great Miami River near Vandalia, and Mad River near Eagle City were selected to represent predominantly agricultural areas upstream from the Dayton metropolitan area. Holes Creek near Kettering is in the Dayton metropolitan area and was selected to represent an urban area in the Great Miami River Basin. Great Miami River at Hamilton is downstream from the Dayton and Hamilton-Middletown metropolitan areas and was selected to represent mixed agricultural and urban land uses of the Great Miami River Basin. Inputs of nitrogen and phosphorus to streams from point and nonpoint sources were estimated for the three agricultural basins and for the Great Miami River Basin as a whole. Nutrient inputs from point sources were computed from the facilities that discharge one-half million gallons or more per day into streams of the Great Miami River Basin. Nonpoint-source inputs estimated in this report are atmospheric deposition and commercial-fertilizer and manure applications. Loads of ammonia, nitrate, total nitrogen, orthophosphate, and total phosphorus from the five sites were computed with the ESTIMATOR program. The computations show nitrate to be the primary component of instream nitrogen loads, and particulate phosphorus to be the primary component of instream phosphorus loads. The Mad River contributed the smallest loads of total nitrogen and total phosphorus to the study area upstream from Dayton, whereas the Upper Great Miami River (upstream from Vandalia) contributed the largest loads of total nitrogen and total phosphorus to the Great Miami River Basin

    This is a biographical note on the life of Dr. Alexander Postoyev, a victim of Stalin's purge of Soviet astronomers in 1936 - 1937. Together with his family, he left the Soviet Union in 1943 and lived in Germany as a refugee and a "displaced person" until 1952, when he moved to Brazil. There, he started the second part of his professional career. Thanks to his efforts, the Astronomical and Geophysical Institute (IAG) of the University of Sao Paulo (USP) was for the first time included in programs of international cooperation, thus contributing to the institutional consolidation of IAG/USP as a leading center of astronomical research and teaching in Brazil now.

  15. Origin of Silurian reefs in the Alexander Terrane of southeastern Alaska

    SciTech Connect

    Soja, C.M. )

    1991-04-01

    Lower to Upper Silurian (upper Llandovery-Ludlow) limestones belonging to the Heceta Formation record several episodes of reef growth in the Alexander terrane of southeastern Alaska. As the oldest carbonates of wide-spread distribution in the region, the Heceta limestones represent the earliest development of a shallow-marine platform within the Alexander arc and the oldest foundation for reef evolution. These deposits provide important insights into the dynamic processes, styles, and bathymetry associated with reef growth in tectonically active oceanic islands. Massive stromatoporoids, corals, and red algae are preserved in fragmental rudstones and represent a fringing reef that formed at the seaward edge of the incipient marine shelf. Accessory constituents in this reef include crinoids and the cyanobacterium Girvanella. Small biostromes were constructed by ramose corals and stromatoporoids on oncolitic substrates in backreef or lagoonal environments. These buildups were associated with low-diversity assemblages of brachiopods and with gastropods, amphiporids, calcareous algae and cyanobacteria. Microbial boundstones reflect the widespread encrustation of cyanobacteria and calcified microproblematica on shelly debris as stromatolitic mats that resulted in the development of a stromatactoid-bearing mud mound and a barrier reef complex. Epiphytaceans, other microbes, and aphrosalpingid sponges were the primary frame-builders of the barrier reefs. These buildups attained significant relief at the shelf margin and shed detritus as slumped blocks and debris flows into deep-water sites along the slope. The similarity of these stromatolitic-aphrosalpingid reefs to those from Siluro-Devonian strata of autochthonous southwestern Alaska suggests paleobiogeographic ties of the Alexander terrane to cratonal North America during the Silurian.

  16. Alexander Fleming, citrated blood and penicillin: paths not pursued and applications delayed.

    PubMed

    Mortimer, P P

    2009-12-01

    Ninety years ago Alexander Fleming (later to discover penicillin) jointly wrote a description of the use of indirect transfusions of citrated blood at a World War 1 (WW1) base hospital. It was the longest series yet to be published, incorporating what was then a novel procedure for treating war casualties. Returning to civilian life Fleming, a qualified surgeon and bacteriologist, chose a different career path, and not until the wars of the late 1930s were the advances in transfusion in WW1 fully incorporated into the management of trauma and haemorrhage. Like penicillin, the benefits of indirect transfusion were only slowly realised.

  17. Changes in saltwater intrusion in the Biscayne aquifer, Hialeah-Miami Springs area, Dade County, Florida

    USGS Publications Warehouse

    Klein, Howard; Ratzlaff, Karl W.

    1989-01-01

    A lobe of salty groundwater that had intruded the Hialeah-Miami Springs area municipal well field, adjacent to the Miami and Tamiami Canals in Dade County, Florida, was stabilized after flow-regulation structures were installed in the canals in 1946. However, in 1971, the saltwater began to readvance toward the center of the well field because of water level declines caused by large increases in withdrawals during a near-record dry season. To better protect the well field, a temporary flow-regulation structure, constructed in 1971, in the Tamiami Canal was moved in 1976 to a permanent site, about 3,000 ft farther seaward; this converted that tidal reach of canal to a controlled reach under a sustained freshwater head.

  2. Tourism and the Hispanicization of race in Jim Crow Miami, 1945-1965.

    This article examines how Miami's significant presence of Anglo Caribbean blacks and Spanish-speaking tourists critically influenced the evolution of race relations before and after the watershed 1959 Cuban Revolution. The convergence of people from the American South and North, the Caribbean, and Latin America created a border culture in a city where the influx of Bahamian blacks and Spanish-speakers, especially tourists, had begun to alter the racial landscape. To be sure, Miami had many parallels with other parts of the South in regard to how blackness was understood and enforced by whites during the first half of the twentieth century. However, I argue that the city's post-WWII meteoric tourist growth, along with its emergence as a burgeoning Pan-American metropolis, complicated the traditional southern black-white dichotomy. The purchasing power of Spanish-speaking visitors during the postwar era transformed a tourist economy that had traditionally catered to primarily wealthy white transplanted Northerners. This significant change to the city's tourist industry significantly influenced white civic leaders' decision to occasionally modify Jim Crow practices for Latin American vacationers. In effect, Miami's early Latinization had a profound impact on the established racial order as speaking Spanish became a form of currency that benefited Spanish-speaking tourists—even those of African descent. Paradoxically, this ostensibly peculiar racial climate aided the local struggle by highlighting the idiosyncrasies of Jim Crow while perpetuating the second-class status of native-born blacks.

    2006-01-01

    Background and Purpose The relationship between abnormal postural coordination and back pain is unclear. The Alexander Technique (AT) aims to improve postural coordination by using conscious processes to alter automatic postural coordination and ongoing muscular activity, and it has been reported to reduce low back pain. This case report describes the use of the AT with a client with low back pain and the observed changes in automatic postural responses and back pain. Case Description The client was a 49-year-old woman with a 25-year history of left-sided, idiopathic, lumbrosacral back pain. Automatic postural coordination was measured using a force plate during horizontal platform translations and one-legged standing. Outcomes The client was tested monthly for 4 months before AT lessons and for 3 months after lessons. Before lessons, she consistently had laterally asymmetric automatic postural responses to translations. After AT lessons, the magnitude and asymmetry of her responses and balance improved and her low back pain decreased. Discussion Further research is warranted to study whether AT lessons improve low back pain–associated abnormalities in automatic postural coordination and whether improving automatic postural coordination helps to reduce low back pain.

    The interpretation of the extent of late Wisconsin glaciation in southeastern Alaska has varied between geologists and biologists. Maps and reports of the region prepared by geologists commonly indicated that late Wisconsin ice extended as a large uniform front west to the edge of the continental shelf. However, the distribution of plants and animals in the region has led many biologists to suggest that there may have been ice-free areas that served as refugia during the late Wisconsin. Based on analyses of aerial photographs, topographic maps, and bathymetric charts, in conjunction with a review of previous literature and reconnaissance fieldwork throughout the region, this study presents data supporting a limited ice extent in the Alexander Archipelago during the late Wisconsin and identifies possible ice-free areas that may have served as refugia. These areas include (1) the Fairweather Ground, (2) the Herbert Graves Island area, (3) the western coast of southern Baranof Island and adjacent continental shelf, (4) Coronation Island and the adjacent continental shelf, (5) the Warren Island area, (6) the continental shelf from west of Heceta Island to Forrester Island in the south, (7) parts of the west coast of southern Dall Island, and (8) lowland areas in southern Prince of Wales Island. The identification of these possible refugia has bearing on the recolonization of the Alexander Archipelago, as they could have served as centers of biotic dispersal upon regional deglaciation and as stepping stones for early humans with a maritime tradition entering the western hemisphere from Asia. ?? 2007 NRC Canada.

  6. Trace element analysis of Alexander the Great's silver tetradrachms minted in Macedonia

    The coinage of Alexander the Great presents a special interest because of its international character in the frame of the ancient times. At least 31 mints (from Aigai to Babylon and from Pella to Alexandreia) operated in the vast state, which was created by Alexander in just over 10 years (334-323 BC). Impressive quantities of tetradrachms were consequently minted for the economic affairs of an expanding state. The mints continued to be active and after the premature death of the Macedonian king, producing among others and tetradrachms in his name. The elemental chemical composition of silver tetradrachms minted in Amphipolis as well as in other Macedonian Greek cities was analysed by energy dispersive X-ray fluorescence (EDXRF), and 12 elements were determined. The problem of the patina (silver corrosion layer) effects on the results was examined by analysis before and after the corrosion product removal. From the results of the chemical composition, a similar numismatic policy is deduced for all the analysed coin as well as metal provenance indications for some of the coins.

  7. Alexander of Macedon, the greatest warrior of all times: did he have seizures?

    PubMed

    Hughes, John R

    2004-10-01

    Alexander the Great (356-323 BC) was likely "the most incomparable general the world has ever seen." His name is often listed among the famous individuals in history who have had seizures. Examination of his illnesses reveals that in 333 BC he entered Tarsus, hot and exhausted, and plunged himself into the River Cydnus, ice-cold from melting mountain snows. His cramps were so severe that he was rescued half-conscious and ashen white, and quickly developed acute pneumonia. Only one doctor dared give him a medication, known for producing powerful and immediate effects. Immediately after drinking this medicine "he lost his speech and falling into a swoon, he had scarcely any sense or pulse left" (Plutarch, ad 75). His reactions were the direct effect of the medication, and this and only this phrase represents the "evidence" for epilepsy. None of his other illnesses involved seizures. Clearly, Alexander the Great did not have epilepsy and his name should be removed from the list of famous individuals who have had seizures.

  8. Geohydrology and water-chemistry of the Alexander Valley, Sonoma County, California

    2006-01-01

    This study of the geohydrology and water chemistry of the Alexander Valley, California, was done to provide an improved scientific basis for addressing emerging water-management issues, including potential increases in water demand and changes in flows in the Russian River. The study tasks included (1) evaluation of existing geohydrological, geophysical, and geochemical data; (2) collection and analysis of new geohydrologic data, including subsurface lithologic data, ground-water levels, and streamflow records; and (3) collection and analysis of new water-chemistry data. The estimated total water use for the Alexander Valley for 1999 was approximately 15,800 acre-feet. About 13,500 acre-feet of this amount was for agricultural use, primarily vineyards, and about 2,300 acre-feet was for municipal/industrial use. Ground water is the main source of water supply for this area. The main sources of ground water in the Alexander Valley are the Quaternary alluvial deposits, the Glen Ellen Formation, and the Sonoma Volcanics. The alluvial units, where sufficiently thick and saturated, comprise the best aquifer in the study area. Average recharge to the Alexander Valley is estimated from a simple, basinwide water budget. On the basis of an estimated annual average of 298,000 acre-feet of precipitation, 160,000 acre-feet of runoff, and 113,000 to 133,000 acre-feet of evapotranspiration, about 5,000 to 25,000 acre-feet per year is available for ground-water recharge. Because this estimate is based on differences between large numbers, there is significant uncertainty in this recharge estimate. Long-term changes in ground-water levels are evident in parts of the study area, but because of the sparse network and lack of data on well construction and lithology, it is uncertain if any significant changes have occurred in the northern part of the study area since 1980. In the southern half of the study area, ground-water levels generally were lower at the end of the 2002 irrigation

  14. Finding revelation in anthropology: Alexander Winchell, William Robertson Smith and the heretical imperative.

    PubMed

    Livingstone, David N

    2015-09-01

    Anthropological inquiry has often been considered an agent of intellectual secularization. Not least is this so in the sphere of religion, where anthropological accounts have often been taken to represent the triumph of naturalism. This metanarrative, however, fails to recognize that naturalistic explanations could sometimes be espoused for religious purposes and in defence of confessional creeds. This essay examines two late nineteenth-century figures--Alexander Winchell in the United States and William Robertson Smith in Britain--who found in anthropological analysis resources to bolster rather than undermine faith. In both cases these individuals found themselves on the receiving end of ecclesiastical censure and were dismissed from their positions at church-governed institutions. But their motivation was to vindicate divine revelation, in Winchell's case from the physical anthropology of human origins and in Smith's from the cultural anthropology of Semitic ritual.

    On March 27, 1980, the semi-submersible platform Alexander L. Kielland broke down in a storm in the North Sea, resulting in a loss of 123 lives. The investigation subsequently performed by the inquiry commission showed that one of the lower tubular bracings had failed by fatigue. As a result, the vertical leg attached to it was torn off, and the platform capsized. The fatigue fracture had started from a double fillet weld joining a 0.325-m tubular attachment to the bracing. The fillet welds were partially cracked in the early history of the platform due to lammelar tearing. Cumulative damage calculations indicated that the design fatigue life of the bracing was inadequate.

  17. The name of the father: conflict between Louis and Alexander Agassiz and the Embiotoca surfperch radiation.

    PubMed

    Bernardi, G

    2009-04-01

    The surfperch genus Embiotoca currently comprises two species, Embiotoca jacksoni, the black surfperch, and Embiotoca lateralis, the striped surfperch. Originally, however, Louis Agassiz described a third species in the genus Embiotoca, the rainbow surfperch, Embiotoca caryi. This latter name was changed by Louis' son, Alexander, to Hypsurus caryi, a name that remains valid. In this study, new molecular data (3545 bp of DNA from four mitochondrial and two nuclear DNA regions) indicated that the rainbow surfperch should be retained within the genus Embiotoca, a result consistent with recent morphological data. Adaptive radiation combined with sexual selection resulting in rapid morphological changes in the rainbow surfperch may have contributed to the conflicting position of this species.

    Alexander disease (AxD) is the only known human pathology caused by mutations in an astrocyte-specific gene, glial fibrillary acidic protein (GFAP). These mutations result in abnormal GFAP accumulations that promote seizures, motor delays and, ultimately, death. The exact contribution of increased, abnormal levels of astrocytic mutant GFAP in the development and progression of the epileptic phenotype is not clear, and we addressed this question using two mouse models of AxD. Comparison of brain seizure activity spontaneously and after traumatic brain injury (TBI), an effective way to trigger seizures, revealed that abnormal GFAP accumulation contributes to abnormal brain activity (increased interictal discharges) but is not a risk factor for the development of epilepsy after TBI. These data highlight the need to further explore the complex and heterogeneous response of astrocytes towards injury and the involvement of GFAP in the progression of AxD. PMID:25069089

  20. Silurian trace fossils in carbonate turbidites from the Alexander Arc of southeastern Alaska

    SciTech Connect

    Soja, C.M. )

    1990-05-01

    Early to Late Silurian (Wenlock-Ludlow) body and trace fossils from the Heceta Formation are preserved in the oldest widespread carbonates in the Alexander terrane of southeastern Alaska. They represent the earliest shelly benthos to inhabit a diversity of marine environments and are important indicators of the early stages in benthic community development within this ancient island arc. The trace fossils are significant because they add to a small but growing body of knowledge about ichnofaunas in deep-water Paleozoic carbonates. Proximal to medial carbonate turbidites yield a low-diversity suite of trace fossils that comprises five distinct types of biogenic structures. Bedding planes reveal simple epichnial burrows (Planolites), cross-cutting burrows (Fucusopsis), and tiny cylindrical burrows. These and other casts, including chondrites( )-like burrow clusters, represent the feeding activities (fodinichnia) of preturbidite animals. Hypichnial burrows and rare endichnial traces reflect the activities of postturbidite animals. Broken and offset traces indicate that infaunal biota commenced burrowing before slumping and subsequent soft-sediment deformation. The abundance and density of trace fossils increases offshore in the medial turbidites associated with a decrease in the size and amount of coarse particles and with an increase in mud and preserved organic material. Although diversity levels are similar in the proximal and medial turbidite facies, they are much lower than in Paleozoic siliciclastic turbidites. This may reflect unfavorable environmental conditions for infaunal biota or paleobiogeographic isolation of the Alexander terrane during the Silurian. A greater use of trace fossils in terrane analysis will help to resolve this issue and should provide new data for reconstructing the paleogeography of circum-Pacific terranes.

    This study examines the association between the presence of drugs and alcohol at time of suicide in Hispanic versus non-Hispanic youth suicide victims in Miami-Dade County, Florida. The Medical Examiner's records of 435 persons aged 24 years or younger classified as suicides in Miami-Dade County, Florida, from 1990 to 2011 were reviewed. Hispanic youth in Miami-Dade County, Florida were 1.62 times more likely than non-Hispanic youth to have used drugs and alcohol at time of suicide (OR 1.62; 95 % CI 1.07-2.04; p = 0.049). Firearm use was significantly associated with drug and alcohol use at time of death. Use of drugs and alcohol at the time of death are important risk factors for suicide in Hispanic youth.

    Producing and retaining physician-scientists remains a major challenge in advancing innovation, knowledge, and patient care across all medical disciplines. Various programs during medical school, including MD-PhD programs, have been instituted to address the need for continued production of physician-scientists. From 1971 through 1989, 508 students with a prior PhD in the sciences, mathematics, or engineering graduated in two years from an accelerated MD program at the University of Miami School of Medicine. The program, designed to address potential clinical physician shortages rather than physician-scientist shortages, quickly attracted many top-notch scientists to medicine. Many program graduates went to top-tier residencies, pursued research careers in academic medicine, and became academic leaders in their respective fields. A retrospective examination of graduates conducted in 2008-2009 demonstrated that approximately 59% took positions in academic university medical departments, 3% worked for governmental agencies, 5% entered industry as researchers or executives, and 33% opted for private practice. Graduates' positions included 85 full professors, 11 university directors or division heads, 14 academic chairs, 2 medical school deans, and 1 astronaut. Overall, 30% of graduates had obtained National Institutes of Health funding after completing the program. These results suggest that accelerated medical training for accomplished scientists can produce a large number of successful physician-scientists and other leaders in medicine. Furthermore, these results suggest that shortening the medical portion of combined MD-PhD programs might also be considered. PMID:20354390

    Objective A cross-sectional study of mixed connective tissue disease (MCTD) was performed to determine if there were identifiable differences in the clinical expression of MCTD associated with race or ethnicity. Methods Miami, Florida, and Midwestern US (Missouri) Caucasian MCTD cohorts were studied. Clinical and laboratory features of the 2 MCTD cohorts were compared. A concurrently collected cohort of Sm-positive patients with systemic lupus erythematosus (SLE) was studied as a control. Disease activity and severity and functional status were measured. CD4+CD25high-expressing T-regulatory cells were enumerated and serum soluble L selectin was measured as biomarkers of disease activity. Results The Miami and Missouri Caucasian MCTD groups, while differing from the SLE group, were largely similar; however, gastroesophageal reflux, sclerodactyly, and malar rash were significantly more frequent in the Missouri MCTD group and alopecia was more frequent in the Miami MCTD group. Significant clinical and laboratory differences were found between the Miami MCTD and Miami SLE groups despite similar disease duration, activity, severity and functional status. Raynaud's phenomenon (RP), hand swelling, synovitis, myositis, and sclerodactyly were all significantly more common in RNP-positive MCTD versus Sm-positive SLE subjects. Conclusion Ethnic differences were observed in the frequency of end-organ involvement in the Miami MCTD versus the Missouri Caucasian MCTD groups. Clinical and laboratory features of all MCTD groups were clearly different from the SLE group, despite similar disease activity, disease severity, and functional status. Disease activity measures appeared to behave similarly as valid measures of disease activity in SLE and MCTD. PMID:18260175

    Between September 17 and November 9, 1962, the U.S. Geological Survey, in cooperation with Ohio Division of Water, Miami Conservancy District, and c,ty of Cincinnati, Ohio, co.,:ducted a refraction seismic study in Hamilton and Butler Counties, southwest Ohio. The area lies between Hamilton, Ohio, and the Ohio River and includes a preglacial valley now occupied by portions of the Miami River, Whitewater River, and Mill Creek. The valley is partially filled with glacial debris which yields large quantities of good-quality water. The object of the study was to determine the thickness of these glacial deposits and the shape of the preglacial valley.

  11. Focused risk assessment: Mound Plant, Miami-Erie Canal Operable Unit 4

    In 1969, an underground waste line at Mound Plant ruptured and released plutonium-238 in a dilute nitric acid solution to the surrounding soils. Most of the acid was neutralized by the native soils. The plutonium, which in a neutral solution is tightly sorbed onto clay particles, remained within the spill area. During remediation, a severe storm eroded some of the contaminated soil. Fine grained plutonium-contaminated clay particles were carried away through the natural drainage courses to the remnants of the Miami-Erie Canal adjacent to Mound Plant, and then into the Great Miami River. This focused risk assessment considers exposure pathways relevant to site conditions, including incidental ingestion of contaminated soils, ingestion of drinking water and fish, and inhalation of resuspended soils and sediments. For each potential exposure pathway, a simplified conceptual model and exposure scenarios have been used to develop conservative estimates of potential radiation dose equivalents and health risks. The conservatism of the dose and risk estimates provides a substantive margin of safety in assuring that the public health is protected.

  12. An overview of urban stormwater-management practices in Miami-Dade County, Florida

    2004-01-01

    Agencies with jurisdiction over stormwater-management systems in Miami-Dade County, Florida, include the Miami-Dade Department of Environmental Resources Management (DERM), South Florida Water Management District (SFWMD), and Florida Department of Transportation (FDOT). These agencies are primarily concerned with minor drainage systems that handle runoff from storms with return periods of 10 years or less (DERM), major drainage systems that handle runoff from storms with return periods of 25 years or more (SFWMD), and runoff from major roadways (FDOT). All drainage regulations require retention of at least a specified water-quality volume (defined volume of surface runoff), typically the first inch of runoff. The DERM and FDOT intensity duration frequency (IDF) curves used as a basis for design are similar but different, with differences particularly apparent for short-duration storms. The SFWMD 25-year 3-day storm incorporates an IDF curve that is substantially different from both the IDF curves of DERM and FDOT. A DERM methodology for designing closed exfiltration systems is applicable to storms of 1-hour duration, but is not applicable to all storms with a given T-year return period. A trench design that is applicable to all storms with a given T-year return period is presented as an alternative approach.

    An examination of the lives and careers of physician-activists Dorothy Boulding Ferebee (1898-1972) and Virginia M. Alexander (1899-1949) demonstrates how Black physicians in the first half of the 20th century used public health to improve the health of Black Americans and provides insights into the experiences of Black women physicians. I discuss their professional and personal backgrounds and analyze their divergent strategies to address health inequities. Ferebee used her leadership in Black women's organizations to develop public health programs and become a national advocate for Black health. Alexander, a Quaker, used her religious connections to urge Whites to combat racism in medicine. She also conducted public health research and connected it to health activism. Both were passionate advocates of health equity long before it gained prominence as a major public health issue. An analysis of their work illuminates past efforts to improve the health of Black Americans.

  12. Alexander Scriabin: his chronic right-hand pain and Its impact on his piano compositions.

    PubMed

    Altenmüller, Eckart

    2015-01-01

    Alexander Scriabin was an outstanding pianist and an avant-garde composer who influenced later generations with his innovative "multimedia" conceptions of aesthetic experience. As an adolescent, he was systematically trained as a concert pianist and received lessons from Vassily Safonoff, one of the founders of the legendary Russian Piano School. At age 20, Scriabin suffered an overuse injury of his right hand when attempting to improve the sound quality of his piano touch. This injury caused a deep crisis and influenced his later composition style in his piano works. From this time on, his works were frequently dominated by unusual virtuosic use and wide spans of his left hand. Rest, restricted repertoire, and an increased focus on composition contributed to recovery; however, he always remained anxious concerning the stamina of his right hand. The case report impressively demonstrates the stressors an aspiring young pianist had to cope with at the end of the nineteenth century. Furthermore, it is a convincing example of how resource-oriented behavior and intuition lead to the improvement of health status. Differential diagnoses and the modern concept of multimodal pain therapy in chronic overuse injury will be discussed from a historical perspective. PMID:25684291

    Eighty years ago, Alexander Fleming described the antibiotic effects of a fungus that had contaminated his bacterial culture, kick starting the antimicrobial revolution. The fungus was later ascribed to a putatively globally distributed asexual species, Penicillium chrysogenum. Recently, the species has been shown to be genetically diverse, and possess mating-type genes. Here, phylogenetic and population genetic analyses show that this apparently ubiquitous fungus is actually composed of at least two genetically distinct species with only slight differences detected in physiology. We found each species in air and dust samples collected in and around St Mary's Hospital where Fleming worked. Genotyping of 30 markers across the genome showed that preserved fungal material from Fleming's laboratory was nearly identical to derived strains currently in culture collections and in the same distinct species as a wild progenitor strain of current penicillin producing industrial strains rather than the type species P. chrysogenum. Global samples of the two most common species were found to possess mating-type genes in a near 1:1 ratio, and show evidence of recombination with little geographic population subdivision evident. However, no hybridization was detected between the species despite an estimated time of divergence of less than 1MYA. Growth studies showed significant interspecific inhibition by P. chrysogenum of the other common species, suggesting that competition may facilitate species maintenance despite globally overlapping distributions. Results highlight under-recognized diversity even among the best-known fungal groups and the potential for speciation despite overlapping distribution.

  14. Testing the equality of students' performance using Alexander-Govern test with adaptive trimmed means

    Analyzing the equality of independent group has to be done with caution. The classical approaches such as ttest for two groups and analysis of variance (ANOVA) for more than two groups always are favorable selection by researchers. However, sometime these methods were abused by the presence of nonnormality or variance heterogeneity or both. It is known that ANOVA is restricted to the assumptions of normality and homogeneity of variance. In real life data, sometimes these requirements are hard to attain. The Alexander-Govern test with adaptive trimmed mean (AG_atm) is one approach that can be chosen as alternative to the classical tests when their assumptions are violated. In this paper, the performances of AG_atm were compared to the original AG test and ANOVA using simulated and real life data. The simulation study proved that the AG_atm performs better than the original AG test and the classical test. For real life data, student's performance in decision analysis course, measured by final examination score was chosen. Based on the exploratory data analysis, this data found to have problem of nonnormality.

    Abstract Florida has the greatest proportion (19%) of older population (65 years or older) in the United States. The age distribution of its residents, in conjunction with a major shift in the leading cause of death within all age groups from acute illnesses to chronic disease, creates unprecedented health care challenges for the state. The objective of this study is to profile the older population living in Miami-Dade County (MDC) using 3 population-based, household-based surveys conducted over the past 5 years. This study examined cross-sectional data (demographics, health outcomes, risk factors, health assess, and utilization) collected from probability-sampled, household-based surveys conducted in 3 areas of MDC: north Miami-Dade, Little Haiti, and South Miami. The questionnaire was administered face-to-face by trained interviewers in English, Spanish, French, or Creole. Analyses were restricted to households containing at least 1 member aged 65 years or older (n = 935). One consenting adult answered the questionnaire on behalf of household members. The mean age of the respondent (60% females) was 60 years. Overall, respondents were predominantly African-Americans, Hispanics, and blacks of Haitian origin. One-third of all households fell below the US poverty thresholds. One-quarter of all households had at least 1 member who was uninsured within the year before the survey. Twenty percent of households had at least 1 member with an acute myocardial infarction or stroke during the year before the survey. Bone density tests and blood stool tests were strikingly underutilized. The health outcomes most prevalent within household members were cardiovascular diseases followed by cancer, anxiety/depression, obesity, asthma, and bone fractures.

    In January 2010, a massive earthquake struck Haiti resulting in unprecedented damage. Little attention, however, has focused on the earthquake's mental health impact in the Haitian diaspora community. As part of an established community-based participatory research initiative in Little Haiti, the predominately Haitian neighborhood in Miami, FL, USA, community health workers conducted surveys with neighborhood residents about earthquake-related losses, coping strategies, and depressive/traumatic symptomology. Findings reveal the earthquake strongly impacted the diaspora community and highlights prominent coping strategies. Following the earthquake, only a small percentage of participants self-reported engaging in any negative health behaviors. Instead, a majority relied on their social networks for support. This study contributes to the discourse on designing culturally-responsive mental health initiatives for the Haitian diaspora and the ability of existing community-academic partnerships to rapidly adapt to community needs.

    This article examines the multifaceted interactions among homelessness, HIV, substance abuse, and gender. Data were collected on 1,366 chronic drug users using a nationally standardized validated instrument within the Miami CARES project of a multisite federally funded program. HIV testing accompanied by pretest and posttest counseling was conducted on-site by certified phlebotomists and counselors. In addition to descriptive analyses and corresponding tests of significance, logistic regression analyses were used to clarify the complex associations between the outcome variables of homelessness and HIV, recognizing difficulties of determining temporal sequence. HIV infection was found to be 2.35 times more prevalent among homeless women than homeless men and significantly higher for homeless women. The findings indicate that among women, homelessness and HIV have a highly interactive effect increasing the vulnerability of this population and thus rendering them an extremely important priority population on which to focus public health efforts and programs.

  1. Correlation analysis of a ground-water level monitoring network, Miami-Dade County, Florida

    2005-01-01

    The U.S. Geological Survey cooperative ground-water monitoring program in Miami-Dade County, Florida, expanded from 4 to 98 continuously recording water-level monitoring wells during the 1939-2001 period. Network design was based on area specific assessments; however, no countywide statistical assessments of network coverage had been performed for the purpose of assessing network redundancy. To aid in the assessment of network redundancy, correlation analyses were performed using S-PLUS 2000 statistical analysis software for daily maximum water-level data from 98 monitoring wells for the November 1, 1973, to October 31, 2000 period. Because of the complexities of the hydrologic, water-supply, and water-management systems in Miami-Dade County and the changes that have occurred to these systems through time, spatial and temporal variations in the degree of correlation had to be considered. To assess temporal variation in correlation, water-level data from each well were subdivided by year and by wet and dry seasons. For each well, year, and season, correlation analyses were performed on the data from those wells that had available data. For selected wells, the resulting correlation coefficients from each year and season were plotted with respect to time. To assess spatial variation in correlation, the coefficients determined from the correlation analysis were averaged. These average wet- and dry-season correlation coefficients were plotted spatially using geographic information system software. Wells with water-level data that correlated with a coefficient of 0.95 or greater were almost always located in relatively close proximity to each other. Five areas were identified where the water-level data from wells within the area remained correlated with that of other wells in the area during the wet and dry seasons. These areas are located in or near the C-1 and C-102 basins (2 wells), in or near the C-6 and C-7 basins (2 wells), near the Florida Keys Aqueduct Authority

  2. Pleistocene barrier bar seaward of ooid shoal complex near Miami, Florida

    An ooid sand barrier bar of Pleistocene age was deposited along the seaward side of an ooid shoal complex southwest of Miami, Florida. The bar is 35 km long, about 0.8 km wide, elongate parallel with the trend of the ooid shoal complex and perpendicular to channels between individual shoals. A depression 1.6 km wide, interpreted as a back-barrier channel, isolates the bar from the ooid shoals. During sea-level fall and subaerial exposure of the bar, the ooid sand was cemented in place, preventing migration of the barrier. No Holocene analogue of this sand body is recognized, perhaps because of the relative youthfulness of Holocene ooid shoals. This Pleistocene ooid shoal complex, with its reservoir-size barrier bar, may serve as a refined model for exploration in ancient ooid sand belts.

    Endemic measles, if it occurs in the United States, will likely be found in cities, because large populations are required to sustain transmission and importations of measles virus are most frequent in cities. We investigated measles surveillance systems in 5 cities (Chicago, Houston, Los Angeles, Miami, New York City) during 1995-1999. The passive reporting of a measles case activated the systems to look for more cases and to intervene to prevent more cases. During 1995-1999, 1363 suspected measles cases were investigated. Only 58 of these were confirmed as measles (0.24 cases/100000 people), and the majority (57%) of confirmed cases were imported or linked to an importation. Most (83%) suspected cases that met the case definition had a complete case investigation, including a laboratory test for measles. We conclude that surveillance in these 5 cities shows no evidence of endemic measles transmission.

    On July 19, 2006, the director of a children's aquatic sports day camp notified the Miami-Dade County Health Department (MDCHD) of three campers who had received a diagnosis of cutaneous larva migrans (CLM), or "creeping eruption," a skin condition typically caused by dog or cat hookworm larvae of the genus Ancylostoma. MDCHD conducted an investigation to determine the source and magnitude of the outbreak and prevent additional illness. This report summarizes the results of that investigation, which identified exposure to cat feces in a playground sandbox as the likely source of infection. Although CLM outbreaks are reported rarely to the Florida Department of Health, evidence indicates that CLM is a potential health hazard in Florida. This disease cluster highlights the importance of appropriate environmental hygiene practices and education in preventing CLM.

  5. Geology and ore deposits of the Globe-Miami district, Arizona

    The rocks of the Globe-Miami district range from lower Precambrian to Recent. The oldest formation, the Pinal schist, comprises several varieties of schist formed by dynamic and thermal metamorphism of shale and feldspathic sandstone during the early Precambrian Mazatzal revolution. During the later stages of this revolution, the schist was intruded by a complex of dioritic rocks and by plutons of granite and quartz monzonite. There were extensive intrusions of a biotite-quartz diorite, known as the Madera diorite, mainly south of the district. In the northern part of the mapped area, the schist was invaded by an extensive mass, the Ruin granite, which is a coarse-grained rock most commonly of quartz monzonitic composition. There are also smaller sill-like masses of slightly gneissic muscovite granite.

    Evaluations of the lithostratigraphy, lithofacies, paleontology, ichnology, depositional environments, and cyclostratigraphy from 11 test coreholes were linked to geophysical interpretations, and to results of hydraulic slug tests of six test coreholes at the Snapper Creek Well Field (SCWF), to construct geologic and hydrogeologic frameworks for the study area in central Miami-Dade County, Florida. The resulting geologic and hydrogeologic frameworks are consistent with those recently described for the Biscayne aquifer in the nearby Lake Belt area in Miami-Dade County and link the Lake Belt area frameworks with those developed for the SCWF study area. The hydrogeologic framework is characterized by a triple-porosity pore system of (1) matrix porosity (mainly mesoporous interparticle porosity, moldic porosity, and mesoporous to megaporous separate vugs), which under dynamic conditions, produces limited flow; (2) megaporous, touching-vug porosity that commonly forms stratiform groundwater passageways; and (3) conduit porosity, including bedding-plane vugs, decimeter-scale diameter vertical solution pipes, and meter-scale cavernous vugs. The various pore types and associated permeabilities generally have a predictable vertical spatial distribution related to the cyclostratigraphy. The Biscayne aquifer within the study area can be described as two major flow units separated by a single middle semiconfining unit. The upper Biscayne aquifer flow unit is present mainly within the Miami Limestone at the top of the aquifer and has the greatest hydraulic conductivity values, with a mean of 8,200 feet per day. The middle semiconfining unit, mainly within the upper Fort Thompson Formation, comprises continuous to discontinuous zones with (1) matrix porosity; (2) leaky, low permeability layers that may have up to centimeter-scale vuggy porosity with higher vertical permeability than horizontal permeability; and (3) stratiform flow zones composed of fossil moldic porosity, burrow

    At the end of summer in 1992 the fishery of the Great Miami River took an unexpected deviation from the stasis of past years as an intense suspended algal bloom decreased the compositional diversity found at the lower GMR stations. Daytime supersaturation of oxygen and elevated pHs, reaching 9 by midday during the month of August, undoubtedly caused severe deficits of oxygen at night. Despite the aeration at every riffle, the intensities of the biological processes in the water were sufficient to cause very high positive and negative excursions of oxygen over the day and night cycle. This report documents a fish harvest that was conducted as part of the oxygen excess/deficit study.

    The Great and Little Miami River Basins drain approximately 7,354 square miles in southwestern Ohio and southeastern Indiana and are included in the more than 50 major river basins and aquifer systems selected for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Principal streams include the Great and Little Miami Rivers in Ohio and the Whitewater River in Indiana. The Great and Little Miami River Basins are almost entirely within the Till Plains section of the Central Lowland physiographic province and have a humid continental climate, characterized by well-defined summer and winter seasons. With the exception of a few areas near the Ohio River, Pleistocene glacial deposits, which are predominantly till, overlie lower Paleozoic limestone, dolomite, and shale bedrock. The principal aquifer is a complex buried-valley system of sand and gravel aquifers capable of supporting sustained well yields exceeding 1,000 gallons per min-ute. Designated by the U.S. Environmental Protection Agency as a sole-source aquifer, the Buried-Valley Aquifer System is the principal source of drinking water for 1.6 million people in the basins and is the dominant source of water for southwestern Ohio. Water use in the Great and Little Miami River Basins averaged 745 million gallons per day in 1995. Of this amount, 48 percent was supplied by surface water (including the Ohio River) and 52 percent was supplied by ground water. Land-use and waste-management practices influence the quality of water found in streams and aquifers in the Great and Little Miami River Basins. Land use is approximately 79 percent agriculture, 13 percent urban (residential, industrial, and commercial), and 7 percent forest. An estimated 2.8 million people live in the Great and Little Miami River Basins; major urban areas include Cincinnati and Dayton, Ohio. Fertilizers and pesticides associated with agricultural activity, discharges from municipal and

    Studies have shown that the environmental conditions of the home are important predictors of health, especially in low-income communities. Understanding the relationship between the environment and health is crucial in the management of certain diseases. One health outcome related to the home environment among urban, minority, and low-income children is childhood lead poisoning. The most common sources of lead exposure for children are lead paint in older, dilapidated housing and contaminated dust and soil produced by accumulated residue of leaded gasoline. Blood lead levels (BLL) as low as 10 microg/dL in children are associated with impaired cognitive function, behavior difficulties, and reduced intelligence. Recently, it is suggested that the standard for intervention be lowered to BLL of 5 microg/dl. The objectives of our report were to assess the prevalence of lead poisoning among children under six years of age and to quantify and test the correlations between BLL in children and lead exposure levels in their environment. This cross-sectional analysis was restricted to 75 children under six years of age who lived in 6 zip code areas of inner city Miami. These locations exhibited unacceptably high levels of lead dust and soil in areas where children live and play. Using the 5 microg/dL as the cutoff point, the prevalence of lead poisoning among the study sample was 13.33%. The study revealed that lead levels in floor dust and window sill samples were positively and significantly correlated with BLL among children (p < 0.05). However, the correlations between BLL and the soil, air, and water samples were not significant. Based on this pilot study, a more comprehensive environmental study in surrounding inner city areas is warranted. Parental education on proper housecleaning techniques may also benefit those living in the high lead-exposed communities of inner city Miami.

    Environmental justice (EJ) research has relied on ecological analyses of socio-demographic data from areal units to determine if particular populations are disproportionately burdened by toxic risks. This article advances quantitative EJ research by (a) examining whether statistical associations found for geographic units translate to relationships at the household level; (b) testing alternative explanations for distributional injustices never before investigated; and (c) applying a novel statistical technique appropriate for geographically-clustered data. Our study makes these advances by using generalized estimating equations to examine distributive environmental inequities in the Miami (Florida) metropolitan area, based on primary household-level survey data and census block-level cancer risk estimates of hazardous air pollutant (HAP) exposure from on-road mobile emission sources. In addition to modeling determinants of on-road HAP cancer risk among all survey participants, two subgroup models are estimated to examine whether determinants of risk differ based on disadvantaged minority (Hispanic and non-Hispanic Black) versus non-Hispanic white racial/ethnic status. Results reveal multiple determinants of risk exposure disparities. In the model including all survey participants, renter-occupancy, Hispanic and non-Hispanic black race/ethnicity, the desire to live close to work/urban services or public transportation, and higher risk perception are associated with greater on-road HAP cancer risk; the desire to live in an amenity-rich environment is associated with less risk. Divergent subgroup model results shed light on the previously unexamined role of racial/ethnic status in shaping determinants of risk exposures. While lower socioeconomic status and higher risk perception predict significantly greater on-road HAP cancer risk among disadvantaged minorities, the desire to live near work/urban services or public transport predict significantly greater risk among

    During the early stages of the drought of 1987-88 in Ohio, a number of diminished capacity complaints were received from domestic well owners in northwestern Montgomery County. Most home owners blamed the nearby Dayton-Miami Well Field (MWF). The MWF is situated in a preglacial, bedrock valley filled with outwash deposits. In this area, sand and gravel outwash deposits from a buried valley aquifer. Glacial outwash also covers that uplands to the west, where a large number of domestic water wells are located. Recharge to the uplands is primarily by infiltration of precipitation. The buried valley aquifer is recharged via infiltration from the Great Miami River and precipitation. Recharge into the valley aquifer is enhanced from man-made recharge lagoons near the well field. Additional recharge to the well field occurs from ground water inflow from north of the well field, and inflow from the adjacent uplands to the east. Temporal changes in the extent of the cone of depression surrounding the well field are shown on potentiometric surface maps. Furthermore, the cone of depression extends into the glacial outwash deposits underlying the upland area, clearly indicating a hydraulic connection between the buried valley aquifer and these glacial outwash deposits beneath the upland area. This expanding cone of depression indicates that increased pumping is exceeding recharge and ground water is being removed from aquifer storage. Ground water levels in the MWF reached their lowest point during the drought of 1987-88. This was the period during which most domestic well failures occurred. If production from the MWF continues to increase and/or this region experience another prolonged drought, dewatering of domestic wells east of the MWF will likely reoccur.

  12. Environmental Impacts of the Annual Agricultural Drawdown in Southern Miami-Dade County

    2008-05-01

    Water managers annually manipulate groundwater storage in Southern Miami-Dade County at the end of the wet season to support agricultural interests. The so-called "agricultural drawdown" in Southern Miami-Dade County involves a 0.8 ft (0.24 m) reduction in groundwater stages via the release of large volumes of water each fall to Biscayne Bay. An average of 21.4 billion gallons (65,800 ac-ft or 8.1x107 m3) of freshwater are released each year from the Biscayne Aquifer via the C-103 and C-102 canals during the drawdown in anticipation of the winter growing season. The side-effects of this groundwater drawdown and loss of stored water are felt primarily by the environment in, and adjacent to, southern Biscayne Bay. Without the rapid drainage of freshwater, these large volumes of water would gradually leak into Biscayne Bay and its low-lying coastal wetlands, providing freshwater flows further into the dry season. The rapid and sudden release of water from the Biscayne Aquifer within a few weeks of the end of the wet season brings about an artificially early start to the dry season. The following dry season is thus unnaturally dry, leading to long periods of dry marshes and high salinities along the shoreline. The result threatens productive estuarine fish and shellfish habitat, enhances predation of nearshore species by marine fish, encourages exotic plant species within the coastal wetland zone, and promotes a loss of wading bird foraging habitat during nesting season. The threat of saltwater intrusion into the Biscayne Aquifer is enhanced by this operational practice as well, since sea levels are at their seasonal maximums in October and November. The effects of the agricultural drawdown, the possible enhancements to the coastal ecosystem that could be realized by its elimination, and its future within the context of the Comprehensive Everglades Restoration Plan's Biscayne Bay Coastal Wetlands project will be explored.

    Early to Late Silurian (Wenlock-Ludlow) limestones belonging to the Heceta Formation reflect bathymetric gradients within the ancient island arc exposed in the Alexander terrane of southeastern Alaska. These rocks record the earliest occurrence of widespread carbonate deposition in the region and represent the earliest foundation for shallow-water platform development within the arc. The excellent preservation of platform, platform margin, and slope deposits contrasts with the poor preservation of many marine sediments that originated within other island arcs. Hence, these limestones provide important insights into the styles, processes, and bathymetry of carbonate deposition in island arcs. Carbonate depositional sites within the arc extended laterally from nearshore intertidal and relatively shallow subtidal zones of a marine platform, to the seaward margins of a rimmed shelf, and into deeper subtidal areas of a slope environment. Fossiliferous deposits that originated on the platform comprise a diversity of shelly benthos, including corals and stromatoporoids in growth position. Dasycladacean algae, oncoids, and Amphipora also indicate shallow-water conditions. Organic buildups and reefs were constructed by cyanobacteria, massive stromatoporoids, corals, and algae at the platform margin. Deposition beyond the seaward edge of the shelf is evident from the carbonate turbidites that consist of skeletal debris of shallow-water derivation and an absence of coarse siliciclastic detritus. Sedimentation and resedimentation along a bathymetric gradient within the arc is especially well illustrated by the carbonate breccias that are enclosed within these deep subtidal sediments. They comprise detached stromatolites and clasts of shallow-water origin that were derived from the platform and its margin during periodic slumping of the shelf edge.

    Although a study using eye-tracking technology to assess the focus of attention when evaluating the beauty of a face demonstrated a marked attentional preference for the eye area (Cula, G.O. et al., Abst P1636), the skin at large is a main factor that reveals information about a person to everyone else with whom he or she comes into contact. Be it because of disease or because of aging, improving the appearance of the skin is as important as relieving pain, itch or other troublesome symptoms caused by skin diseases. Moreover, this can be much more important in a place like South Miami Beach, where bare skin is revealed on much more than just the face ... at least under normal circumstances, when the weather is not as surprisingly chilly as it was in March 2010 during the AAD annual meeting However, if beauty is very important for many people, health is important for everybody, and important news was also discussed on treatments for common and less common cutaneous diseases, ranging from psoriasis, acne and atopic dermatitis to a broad range of blistering, papulosquamous and granulomatous diseases. These are among the most important issues reviewed in the following report, which in combination with expert insight interviews freely accessible from the Access Dermatology website and the full abstracts from the meeting, available for download from the AAD website, will hopefully improve dermatologists' approach to treating skin diseases through use of the most novel therapies. Treatment is important, but so is prevention, and in that sense an important issue discussed during the meeting, which was nicely covered in an interview with Dr. Darrell S. Riegel from the Ronald O. Perelman Department of Dermatology at the New York University School of Medicine, was that protecting the skin from sunlight and artificial tanning beds is essential for preventing malignancies such as melanoma, while not jeopardizing adequate availability of active vitamin D.

    The circular Bokan Mountain complex (BMC) on southern Prince of Wales Island, southernmost Alaska, is a Jurassic peralkaline granitic intrusion about 3 km in diameter that crosscuts igneous and metasedimentary rocks of the Alexander terrane. The BMC hosts significant rare metal (rare earth elements, Y, U, Th, Zr, and Nb) mineralization related to the last stage of BMC emplacement. U–Pb (zircon) and 40Ar/39Ar (amphibole and whole-rock) geochronology indicates the following sequence of intrusive activity: (i) a Paleozoic basement composed mainly of 469 ± 4 Ma granitic rocks; (ii) intrusion of the BMC at 177 ± 1 Ma followed by rapid cooling through ca. 550 °C at 176 ± 1 Ma that was synchronous with mineralization associated with vertical, WNW-trending pegmatites, felsic dikes, and aegirine–fluorite veins and late-stage, sinistral shear deformation; and (iii) intrusion of crosscutting lamprophyre dikes at >150 Ma and again at ca. 105 Ma. The peralkaline nature of the BMC and the WNW trend of associated dikes suggest intrusion during NE–SW rifting that was followed by NE–SW shortening during the waning stages of BMC emplacement. The 177 Ma BMC was synchronous with other magmatic centres in the Alexander terrane, such as (1) the Dora Bay peralkaline stock and (2) the bimodal Moffatt volcanic suite located ~30 km north and ~100 km SE of the BMC, respectively. This regional magmatism is interpreted to represent a regional extensional event that precedes deposition of the Late Jurassic – Cretaceous Gravina sequence that oversteps the Wrangellia and Alexander exotic accreted terranes and the Taku and Yukon–Tanana pericratonic terranes of the Canadian–Alaskan Cordillera.

    Florida invested in preserving the Tequesta Indians' "Stonehenge-like" site along the Miami River. Direct observation, and telecast reports, show that a strong association exists between this area and Native American place names, hurricanes, tornados, a waterspout, and other nearby phenomena. Electromagnetic stimulation of human nervous systems in areas like these, discernable by appropriately sensitive individuals when these types of events occur, could plausibly account for some correct "predictions" of events like earthquakes. Various sensory modalities may be activated there. It may be important to understand other historic aspects associated with cultural artifacts like Miami's Tequesta remains. If it also generates instrumentally detectable signals that correlate with visual, "auditory," or nerve ending "tinglings" like those cited by the psychiatrist Arthur Guirdham in books like his Obsessions, applied physicists could partly vindicate the investment and also provide a net return. Society and comparative religious study may benefit.

  5. Recurrence flooding in Miami Beach as an indicator of accelerating rates of sea level rise along the US Atlantic coast

    2014-12-01

    Since 2006, the coastal community of Miami Beach has experienced an increasing rate of flooding, which caused severe property damage and significant disruptions to daily life. To evaluate the flooding frequency and its causes, we conducted a temporal analysis of tide gauge, rain, media report, insurance claim, and photo records from Miami Beach of the past 16 years. The analysis shows that most flooding events occur after heavy rain (> 80 mm) during high tide conditions, but also after the fall equinox tides regardless of rain events. In 2013, a "clear sky" flooding event also occurred just before the spring equinox. We also evaluated changes in flooding frequency over the past 16 years. Our analysis reveals that since 2006, rain-induced events increased by 33% and tide-induced events quadrupled, from 2 events during 1998-2005 to 8-16 events in 2006-2013. In order to understand the causes for the observed increase in flooding frequency, we analyzed the the nearby Virginia Key tide gauge record. We used the Ensemble Emperical Mode Decomposition (EEMD) technique to evaluate trend change in the record and found a significant acceleration in the rate of sea level rise (SLR) since 2006. The average rate of SLR since 2006 is 9±4 mm/yr, which is significantly higher than the global average rate of 3.2±0.4 mm/yr. We also have looked how SLR in the Miami area relates to the large-scale ocean circulation from a very high resolution global climate model simulation. The model results indicate that a weakening of the entire Gulf Stream system (decrease in kinetic energy) is correlated with increasing sea level in the Miami area. Our results support the hypothesis postulated by previous studies that accelerating rate of SLR along the US Atlantic coast are cause by the weakening of the Gulf Stream (e.g., Ezer et al., 2013).

    2002-04-01

    Atmospheric particulate matter and both wet and dry deposition was collected over a period of nine months at one location in the metropolitan area of Miami, Florida. Molecular distributions and concentrations of n-alkanes, fatty acids, polycyclic aromatic hydrocarbons (PAHs) and hopanes were determined using weekly composite samples over this time period in order to determine temporal variability, and their possible dependence on climatic parameters such as temperature, rainfall and wind direction and frequency. Based on molecular distributions of the compounds studied, potential emission sources for the atmospheric particles were assessed and suggested to be mainly derived from automobile exhaust and natural sources. Although wet and dry deposition processes were observed to remove about equal amounts of organic aerosols from the Miami atmosphere, dry deposition was dominant in the removal of anthropogenically derived compounds such as PAHs and hopanes. Only very limited seasonal trends were observed, while wind direction and frequency was found to be the most important meteorological parameter controlling the temporal variability of the organic aerosols. This is the first detailed report of this nature for the Miami area.

    This study examined the mental health consequences of the January 2010 Haiti earthquake on Haitians living in Miami-Dade County, Florida, 2–3 years following the event. A random-sample household survey was conducted from October 2011 through December 2012 in Miami-Dade County, Florida. Haitian participants (N = 421) were assessed for their earthquake exposure and its impact on family, friends, and household finances; and for symptoms of posttraumatic stress disorder (PTSD), anxiety, and major depression; using standardized screening measures and thresholds. Exposure was considered as “direct” if the interviewee was in Haiti during the earthquake. Exposure was classified as “indirect” if the interviewee was not in Haiti during the earthquake but (1) family members or close friends were victims of the earthquake, and/or (2) family members were hosted in the respondent's household, and/or (3) assets or jobs were lost because of the earthquake. Interviewees who did not qualify for either direct or indirect exposure were designated as “lower” exposure. Eight percent of respondents qualified for direct exposure, and 63% qualified for indirect exposure. Among those with direct exposure, 19% exceeded threshold for PTSD, 36% for anxiety, and 45% for depression. Corresponding percentages were 9%, 22% and 24% for respondents with indirect exposure, and 6%, 14%, and 10% for those with lower exposure. A majority of Miami Haitians were directly or indirectly exposed to the earthquake. Mental health distress among them remains considerable two to three years post-earthquake. PMID:26753105

  8. The grand experiment, a historical account of a museum/school partnership: The Alexander Science Center School of Los Angeles

    Heughins, Andrew R.

    This study tells the history of The Alexander Science Center School, a museum/school partnership between the Los Angeles Unified School District and the California Science Center created with the goal of becoming a national model in elementary science education. To provide a background to the development of the school, this study explores the definition of what constitutes a museum school, including the existence of a formal partnership between a school district and a museum and systemic change in the partner institutions leading to a marriage of formal and informal learning styles. In addition, the literature review explores the unique models of museum/school partnerships developed in the United States. The history of the Alexander Science Center School is told in a narrative style using documentation from the schools development and through interviews with individuals who played key roles, from the schools inception through its opening. The study covers the initiation of concept, architectural design, formation of the partnership, and development of the curriculum. The study also identifies the roadblocks encountered in the schools development and makes recommendations for school districts and institutions seeking to create future museum school projects. In addition, a comparison is made other recently studied museum schools to provide a context for the school's historical and programmatic development.

    A belt of unusual volcanogenic massive sulfide (VMS) occurrences is located along the eastern margin of the Alexander terrane throughout southeastern Alaska and northwestern British Columbia and exhibits a range of characteristics consistent with a variety of syngenetic to epigenetic deposit types. Deposits within this belt include Greens Creek and Windy Craggy, the economically most significant VMS deposit in Alaska and the largest in North America, respectively. The occurrences are hosted by a discontinuously exposed, 800-km-long belt of rocks that consist of a 200- to 800-m-thick sequence of conglomerate, limestone, marine elastic sedimentary rocks, and tuff intercalated with and overlain by a distinctive unit of mafic pyroclastic rocks and pillowed flows. Faunal data bracket the age of the host rocks between Anisian (Middle Triassic) and late Norian (late Late Triassic). This metallogenic belt is herein referred to as the Alexander Triassic metallogenic belt. The VMS occurrences show systematic differences in degree of structural control, chemistry, and stratigraphic setting along the Alexander Triassic metallogenic belt that suggest important spatial or temporal changes in the tectonic environment of formation. At the southern end of the belt, felsic volcanic rocks overlain by shallow-water limestones characterize the lower part of the sequence. In the southern and middle portion of the belt, a distinctive pebble conglomerate marks the base of the section and is indicative of high-energy deposition in a near slope or basin margin setting. At the northern end of the belt the conglomerates, limestones, and felsic volcanic rocks are absent and the belt is composed of deep-water sedimentary and mafic volcanic rocks. This northward change in depositional environment and lithofacies is accompanied by a northward transition from epithermal-like structurally controlled, discontinuous, vein- and pod-shaped, Pb-Zn-Ag-Ba-(Cu) occurrences with relatively simple mineralogy

    Time-domain electromagnetic (TEM) soundings were made in Miami-Dade and southern Broward Counties to aid in mapping the landward extent of saltwater in the Biscayne aquifer. A total of 79 soundings were collected in settings ranging from urban to undeveloped land, with some of the former posing problems of land access and interference from anthropogenic features. TEM soundings combined with monitoring-well data were used to determine if the saltwater front had moved since the last time it was mapped, to provide additional spatial coverage where existing monitoring wells were insufficient, and to help interpret a previously collected helicopter electromagnetic (HEM) survey flown in the southernmost portion of the study area. TEM soundings were interpreted as layered resistivity-depth models. Using information from well logs and water-quality data, the resistivity of the freshwater saturated Biscayne aquifer is expected to be above 30 ohm-meters, and the saltwater-saturated aquifer will have resistivities of less than 10 ohm-meters allowing determination of water quality from the TEM interpretations. TEM models from 29 soundings were compared to electromagnetic induction logs collected in nearby monitoring wells. In general, the agreement of these results was very good, giving confidence in the use of the TEM data for mapping saltwater encroachment.

    The Miami site, excavated in 1937, is in a small "playa" basin on the High Plains surface. The site is one of the earliest documented co-occurrences of Clovis points and mammoth. Reinvestigation of the site and related collections was undertaken to better understand the stratigraphy, geochronology, and archaeology. The basin, 23 m diameter × 1.6 m deep, filled with (1) dark gray silty clay, and (2) near the top of the section, a lens of well-sorted silt or loess. The basin started to fill ca. 13,700 yr B.P., the loess dates to ca. 11,400 yr B.P., and the bone bed probably dates to ca. 11,400-10,500 yr B.P. The loess may be the local manifestation of a "Clovis drought." The partial remains of five mammoths (three adults and two juveniles) were recovered in 1937; no other animal remains are known. The bone is heavily weathered and there are no clear indications of human modification. Artifacts found at the site include three Clovis points and a scraper found among the bones and two flakes and a scraper found on the surface near the playa. The origins of the bone and stone assemblage are uncertain but four scenarios are offered: a successful mammoth kill, an unsuccessful kill with wounded animals dying at the watering hole, opportunistic scavenging following natural deaths, or a palimpsest of multiple deaths following both natural and human causes.

    Fish were collected, using electroshocking techniques, from three sites in the Great Miami River (GMR) (September 7 and 8, 1995) as part of an annual survey for Fernald Environmental Restoration Management Corporation (FERMCO). The objective was to collect fish fillets for uranium analysis and examine the health of the fish community in comparison to data collected during the past eleven years. Samples were taken from upstream (river mile = RM; RM 38) and downstream (RM 19) of the Fernald site as well as from near the Fernald effluent line (RM 24). RM 38 is isolated from upstream fish migration by two dams located near Hamilton, Ohio and fish collected from this site should not be influenced by processes at the downstream sites. Samples of 549 fish from 29 species belonging to nine families provided seventy-two samples for uranium analysis by an independent laboratory. Chemical analysis of water samples collected at each site was used to determine the effect of chemical parameters on the fish community. This study focused on comparison of the density, biomass and diversity of the fish community between sites and between years.

  13. Geologic and hydrogeologic frameworks of the Biscayne aquifer in central Miami-Dade County, Florida

    2014-01-01

    Evaluations of the lithostratigraphy, lithofacies, paleontology, ichnology, depositional environments, and cyclostratigraphy from 11 test coreholes were linked to geophysical interpretations, and to results of hydraulic slug tests of six test coreholes at the Snapper Creek Well Field (SCWF), to construct geologic and hydrogeologic frameworks for the study area in central Miami-Dade County, Florida. The resulting geologic and hydrogeologic frameworks are consistent with those recently described for the Biscayne aquifer in the nearby Lake Belt area in Miami-Dade County and link the Lake Belt area frameworks with those developed for the SCWF study area. The hydrogeologic framework is characterized by a triple-porosity pore system of (1) matrix porosity (mainly mesoporous interparticle porosity, moldic porosity, and mesoporous to megaporous separate vugs), which under dynamic conditions, produces limited flow; (2) megaporous, touching-vug porosity that commonly forms stratiform groundwater passageways; and (3) conduit porosity, including bedding-plane vugs, decimeter-scale diameter vertical solution pipes, and meter-scale cavernous vugs. The various pore types and associated permeabilities generally have a predictable vertical spatial distribution related to the cyclostratigraphy. The Biscayne aquifer within the study area can be described as two major flow units separated by a single middle semiconfining unit. The upper Biscayne aquifer flow unit is present mainly within the Miami Limestone at the top of the aquifer and has the greatest hydraulic conductivity values, with a mean of 8,200 feet per day. The middle semiconfining unit, mainly within the upper Fort Thompson Formation, comprises continuous to discontinuous zones with (1) matrix porosity; (2) leaky, low permeability layers that may have up to centimeter-scale vuggy porosity with higher vertical permeability than horizontal permeability; and (3) stratiform flow zones composed of fossil moldic porosity, burrow

    Patients with five or more chronic conditions drive most Medicare costs. Our organization, ChenMed, developed a scalable primary care-led delivery model that focuses on this population while getting reimbursed through full-risk capitation by Medicare Advantage plans. ChenMed is a primary care-led group practice based in Florida that serves low-to-moderate-income elderly patients, largely through the Medicare Advantage program. Our model includes a number of innovations: a one-stop-shop approach for delivering multispecialty services in the community, smaller physician panel sizes of 350-450 patients that allow for intensive health coaching and preventive care, on-site physician pharmacy dispensing, a collaborative physician culture with peer review, and customized information technology. These innovations have improved patient medication adherence, increased the time doctors and patients spend together, and led to high rates of patient satisfaction. Additionally, our Medicare patients have substantially lower rates of hospital use than their peers in the Miami Medicare market. Creating chronic disease centers focused on seniors with multiple chronic conditions is a promising delivery system innovation with major potential to improve the cost and quality of care.

    Purpose. Kaposi's sarcoma (KS) is a rare low-grade vascular tumor associated with the human herpes virus 8. By analyzing the epidemiology, staging, and treatment of KS, we hoped to improve the quality of care at our institution. Methods. Review of the Mount Sinai Medical Center tumor registry database in Miami Beach, FL, USA, identified 143 cases of KS between January 1, 1987 and December 31, 2007. Results. The majority of patients were non-Hispanic whites, non smoking males diagnosed between 1987 and 1996. Most of the patients were HIV positive, with an equal percentage diagnosed with local or distant disease. Most patients received no chemotherapy or radiation. There were no significant differences in patient survival based on sex, HIV status, or radiation received. There was a trend toward improved survival among older patients who smoked, received no chemotherapy, and had localized stage at diagnosis. Multivariate analysis revealed that non-Hispanic whites had a significant worse survival than Hispanic whites (HR = 0.55, 95% CI (0.33, 0.90), P = 0.02). Patients diagnosed between 1987 and 1996 had a worse survival than those between 1997 and 2007 (HR = 0.33 (95% CI 0.19, 0.55), P < 0.0001). Conclusion. This large retrospective study provides further insight into KS. Ethnicity and date of diagnosis are important predictors of long-term survival. PMID:23320191

    The electrofishing survey of fish from the Great Miami River at RM 19, 24 and 38 from late summer 1996 demonstrated the sensitivity of the fish community to microhabitat variation. The variation was particularly clear between the pooled, low flow sections of the river and the runs, where fast current habitats occurred. In 1996, like most recent years, the differences were obvious between Rm 24 and RM 19 and RM 38. River Mile 24 was characterized by a fish community of current-loving fish, dominated by Catastomidae (suckers), and Ictaluridae (catfish). In contrast, samples from pooled stations at RM 19 and 38 were dominated by Centrarchidae, Clupeidae and Cyprinidae, particularly the carp. The microhabitats sampled around the abutments of bridges at RM 19 and 38 where fast current and physical structure occurred, both resembled the community at RM 24. Changes in the fish communities associated with the upstream/downstream changes in stream volume, channel size, morphology, etc., were evidenced by the community coefficients which showed least similarity between the most distant sites.

    Sixty percent of African Americans have had an HIV test, yet this population disproportionately contributes to AIDS mortality, suggesting that testing is not occurring early enough to achieve optimal outcomes. OraQuick, the first Food and Drug Administration-approved home-based HIV rapid test (HBHRT) could potentially increase testing rates. We assessed whether community health workers (CHWs) paired with HBRHT could improve HIV screening and health care access among African Americans in Miami, Florida. In October-November 2013, 60 African Americans were enrolled and randomized to the experimental condition, which received CHW assistance to complete HBHRT, or the control condition, which were instructed to complete HBHRT independently. Intervention participants were significantly (p ≤ .05) more likely than control participants to complete HBHRT and, if positive, get linked to HIV care (100% vs. 83%) χ(2) (1, N = 60) = 5.46, p ≤ .02. We concluded that CHW-assisted HBHRT may be a promising strategy to improve HIV testing and care among African Americans. PMID:27091604

    Twenty pilot-scale test plots were constructed in mid-1998 at the Cyprus Miami mine to investigate the feasibility and cost-effectiveness of various reclamation strategies for establishment of self-sustaining native vegetation on acidic copper tailings. Four reclamation strategies are being tested: (1) directly covering acidic tailings with varying thicknesses f cover soil; (2) removing and/or neutralizing particularly acidic surgical tailings before soil cover placement, (3) chemically and/or physically inhibiting upward water and solute movement using neutralizing and neutral capillary barriers, and (4) constructing a subgrade of neutral tailings beneath cover soil. Preliminary results suggest that thicker soil covers and capillary barrier test plots initially support vegetation to a greater extent than other test plots, probably because of their increased moisture storage capacity. Results also suggest that salts are beginning to migrate upward from underlying tailings into cover soil. Data collected from ongoing vegetation surveys and soil testing will be used to evaluate the effect of various reclamation strategies on vegetation establishment and the potential impact of upward salt migration.

    1982-01-01

    Over a two year period, the Miami-Dade Public Library System gave 12 free solar energy programs throughout Dade County in its various branches; Solar Water Heater Workshops, where registered participants actually took part in building or putting together a solar water heater. Kick-off programs were also given free-of-charge by a number of local solar companies, to inform the audience about solar energy in general and the solar workshops in particular. Average registered attendance at these workshops was twenty, not including the crowds of onlookers at the outdoor building sessions or the earlier kick-off programs, which often had an audience of sixty or more. A later phone check of ten workshop participants picket at random revealed four who had built or were building their own solar systems, three who were considering the purchase of -or had already bought - a domestic solar water heater, one who was reported to be no longer interested by his son, and two who could not be reached. One of the completed heaters has been donated to a local Girl Scout troop, where it is on permanent exhibit; another will be placed in a new library branch, with appropriate publicity about its source. Florida Power and Light, which formerly viewed our early workshops with suspicion, sent a speaker to our final program to announce financial assistance to those who wanted to buy a solar hot water heater.

    Hypereutectoid steels containing between about 1 and 2.1 wt%C, and now known as ultrahigh carbon steels (UHCS), have both a rich history (dating back to the time of Alexander the Great, i.e. {approximately} 300 BC) and an interesting, recent, technological period of development (from 1975 to the present). The connections between the modern UHCS and their ancient counterparts, and in particular Damascus steels, have received considerable attention. In addition to monolithic products, UHCS have also been used in both ancient and modern times in laminated composites. In the present paper, a summary of the modern development of UHCS and UHCS-containing laminates is given, and parallels are drawn with ancient materials. Also, ancient laminated composites containing other steels are described; controversial issues and a possible solution related to the age of such a laminate found in the Great Pyramid of Gizeh are discussed.

    Alexander Ivanov was an outstanding Russian painter who lived in the middle of the nineteenth century, during the romantic period. He did not accept romanticism but instead tried to create his own original style, an ambitious combination of spiritual profundity and a manner of execution unparalleled in Western European art. Ivanov's intention and style are best reflected in his major work The Appearance of Christ to the People, a picture on which he worked for over 20 years. He painted more than 400 sketches of the picture while attempting to bring his masterpiece to perfection. At the end of his life Ivanov became disillusioned, renounced his strong religious conviction and became suspicious. This study examines the influence of his background, life story and personality on the creative process. From a diagnostic perspective, Ivanov's personality featured obsessive, narcissistic and schizoid traits. In his final years he suffered from a delusional disorder. PMID:15682233

    During the late Wisconsin glaciation (circa 26,000-13,000 carbon-14 yr BP) the Cordilleran glacier complex formed vast ice fields and large glaciers along the crest of the Coast Mountains. As these glaciers flowed west to the Pacific Ocean, they were joined by local glaciers originating on the higher reaches of the Alexander Archipelago (Mann and Hamiltion, 1995). This extensive volume of ice was channeled into deep troughs (present-day fiords) that formed major outlet glaciers, such as the glaciers that occupied Chatham Strait and Dixon Entrance. In several places along the coast, deep glacially scoured submarine troughs indicate that glaciers reached to the edge of the continental shelf. For instance, the glacier that extended into the Dixon Entrance trough is known to have extended to the edge of the continental shelf. Its retreat began sometime after 16,000-15,000 carbon-14 yr BP (Barrie and Conway, 1999).

    James Sowerby included meteorites in his publications of British and exotic natural history and so raised interest in their nature and origins at a time of much debate and involving the President of the Royal Society, Sir Joseph Banks. The celebrations over the defeat of France in 1814 prompted Sowerby to make a sword from the Cape of Good Hope iron meteorite to present to the Russian Emperor, Alexander I, at the time of his state visit to London in June 1814 and in recognition of his achievements in bringing peace to Europe. The story of its attempted presentation, its final reception and the following response, including publications, all helped to increase interest in meteorites and their properties. The rediscovery of the sword after a lengthy disappearance probably brings an unusual saga to a fitting close.

    Although numerous studies have been conducted on the vulnerability of marginalized groups in the environmental justice (EJ) and hazards fields, analysts have tended to lump people together in broad racial/ethnic categories without regard for substantial within-group heterogeneity. This paper addresses that limitation by examining whether Hispanic immigrants are disproportionately exposed to risks from flood hazards relative to other racial/ethnic groups (including US-born Hispanics), adjusting for relevant covariates. Survey data were collected for 1283 adult householders in the Houston and Miami Metropolitan Statistical Areas (MSAs) and flood risk was estimated using their residential presence/absence within federally-designated 100-year flood zones. Generalized estimating equations (GEE) with binary logistic specifications that adjust for county-level clustering were used to analyze (separately) and compare the Houston (N = 546) and Miami (N = 560) MSAs in order to clarify determinants of household exposure to flood risk. GEE results in Houston indicate that Hispanic immigrants have the greatest likelihood, and non-Hispanic Whites the least likelihood, of residing in a 100-year flood zone. Miami GEE results contrastingly reveal that non-Hispanic Whites have a significantly greater likelihood of residing in a flood zone when compared to Hispanic immigrants. These divergent results suggest that human-flood hazard relationships have been structured differently between the two MSAs, possibly due to the contrasting role that water-based amenities have played in urbanization within the two study areas. Future EJ research and practice should differentiate between Hispanic subgroups based on nativity status and attend to contextual factors influencing environmental risk disparities. PMID:27490561

Miami GEE results contrastingly reveal that non-Hispanic Whites have a significantly greater likelihood of residing in a flood zone when compared to Hispanic immigrants. These divergent results suggest that human-flood hazard relationships have been structured differently between the two MSAs, possibly due to the contrasting role that water-based amenities have played in urbanization within the two study areas. Future EJ research and practice should differentiate between Hispanic subgroups based on nativity status and attend to contextual factors influencing environmental risk disparities.

    Since intensive farming practices are essential to produce enough food for the increasing population, farmers have been using more inorganic fertilizers, pesticides, and herbicides. Agricultural lands are currently one of the major sources of non-point source pollution. However, by changing farming practices in terms of tillage and crop rotation, the levels of contamination can be reduced and the quality of soil and water resources can be improved. Thus, there is a need to investigate the amalgamated hydrologic effects when various tillage and crop rotation practices are operated in tandem. In this study, the Soil Water Assessment Tool (SWAT) was utilized to evaluate the individual and combined impacts of various farming practices on flow, sediment, ammonia, and total phosphorus loads in the Little Miami River basin. The model was calibrated and validated using the 1990-1994 and 1980-1984 data sets, respectively. The simulated results revealed that the SWAT model provided a good simulation performance. For those tested farming scenarios, no-tillage (NT) offered more environmental benefits than moldboard plowing (MP). Flow, sediment, ammonia, and total phosphorus under NT were lower than those under MP. In terms of crop rotation, continuous soybean and corn-soybean rotation were able to reduce sediment, ammonia, and total phosphorus loads. When the combined effects of tillage and crop rotation were examined, it was found that NT with continuous soybean or corn-soybean rotation could greatly restrain the loss of sediments and nutrients to receiving waters. Since corn-soybean rotation provides higher economic revenue, a combination of NT and corn-soybean rotation can be a viable system for successful farming.

    Fish sampling by electroshocking in the Great Miami River upstream and downstream the Fernald site (September 25 and 26, 1994) was designed to determine changes in the health of the fish community compared to the previous ten years and to collect samples for uranium analyses in fish fillets. Samples of 853 fish, from 27 species, eight families and three sites at river mile (RM) 38, RM 24, and RM 19 provided seventy-eight samples for uranium analyses by an independent laboratory. The biomass of fish caught per hour was greatest at RM 24 > RM 19 > RM 3 8. The diversity index and the heaviest fish community was RM 24 > RM 38 > RM 19. The pooled site at RM 38 near Hamilton was diagnostically separated from the other sites by the young-of-the-year (YOY) golden redhorse, smallmouth bass and golden shiner. The darns at Hamilton acted as an effective barrier against fish migration upriver. Larger freshwater drum, gizzard shad, channel catfish and flathead catfish, which might be expected in rapid current reaches of mid-sized rivers characterize RM 24. The pool at RM 19 was distinguished from the others by YOY gizzard shad, bluegill, and longear sunfish. Thus the fish community in 1994 was separated ecologically by the physical features of the habitat more than by water quality differences between sites. These data suggest that the Fernald effluents in September were having no detectable effects on the distribution of fishes, independent of changes in habitat quality separated on physical attributes of the river channel at each site.

    Square array electrical soundings were made at 13 sites in the Biscayne Aquifer distributed between 1 and 20 km from the shoreline. These soundings were modeled to investigate how resistivity varies spatially and with depth in the upper 15 m of the aquifer. Porosity was estimated from the modeled formation resistivity and observed pore fluid resistivity with Archie's Law. The models were used to interpolate resistivity and porosity surfaces at -2, -5, -8, and -15 m elevations. Modeled resistivity in the unsaturated zone is generally higher than 300 Ω m with the resistivity at sites with thick unsaturated zones greater than 1000 Ω m. Resistivity in the saturated zone ranges from 30 to 320 Ω m. At many sites in the western portions of the study area, resistivity is constant or increases with depth whereas sites in the center of the Atlantic Coastal Ridge exhibit a distinct low resistivity zone (ρ < 45 Ω m) at elevations ranging between -5 and -10 m. At one site near the shore of Biscayne Bay, the resistivity is less than 10 Ω m at -5 m elevation reflecting the presence of salt water in the aquifer. The estimated porosity ranges between 14% and 71% with modal values near 25%. The porosity structure varies both with depth and spatially. Western sites exhibit a high porosity zone at shallow depths best expressed in a NE-SW trending zone of 40-50% porosity situated near the western margin of the Atlantic Coastal Ridge. This zone roughly corresponds in depth with the Q5 chronostratigraphic unit of the Miami Fm. which constitutes the upper flow unit of the Biscayne Aquifer. The highest porosity (>50%) is seen at elevations below -5 m at sites in the center of the Atlantic Coastal Ridge and likely corresponds to solution features. The general NE-SW trend of the resistivity and porosity structure suggests a causal connection with the Pleistocene paleogeography and sedimentary environments.

    Introduction Farmers market-based interventions, including the Farmers’ Market Nutrition Program of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), represent a promising strategy for improving dietary behaviors in low-income communities. Little is known, however, about the health-related characteristics of low-income parents who frequent farmers markets in urban settings. The objective of this study was to examine the relationship between family-health factors and the use of farmers markets by mothers of WIC recipients. Methods We recruited a convenience sample of mothers of children seeking care at a primary care clinic in a large urban public hospital in Miami, Florida, in 2011 (n = 181 total). The clinic was adjacent to a newly established farmers market at the hospital. Each mother completed an interviewer-administered survey that included self-reported measures of maternal and child health, acculturation, dietary behaviors, food insecurity, and use of farmers markets. Results Reported use of farmers markets was independently associated with maternal history of diabetes (odds ratio [OR], 6.9; 95% confidence interval [CI], 1.3–38.3) and increased maternal vegetable (but not fruit) consumption (OR, 3.5; 95% CI, 1.5–8.1). Intended future use of farmers markets was independently associated with being unemployed (OR, 2.4; 95% CI, 1.0–5.7), increased maternal vegetable consumption (OR, 2.5; 95% CI, 1.1–5.7), and food insecurity (OR, 3.6; 95% CI, 1.3–10.3). Conclusions This study provides a snapshot of factors associated with farmers market use in a diverse population of urban low-income families. Understanding these factors may inform public health approaches to increase fresh fruit and vegetable consumption in communities at high risk for preventable chronic conditions. PMID:23764344

    2015-09-01

    Recent environmental justice (EJ) research has emphasized the need to analyze social inequities in the distribution of natural hazards such as hurricanes and floods, and examine intra-ethnic diversity in patterns of EJ. This study contributes to the emerging EJ scholarship on exposure to flooding and ethnic heterogeneity by analyzing the racial/ethnic and socioeconomic characteristics of the population residing within coastal and inland flood risk zones in the Miami Metropolitan Statistical Area (MSA), Florida—one of the most ethnically diverse MSAs in the U.S. and one of the most hurricane-prone areas in the world. We examine coastal and inland flood zones separately because of differences in amenities such as water views and beach access. Instead of treating the Hispanic population as a homogenous group, we disaggregate the Hispanic category into relevant country-of-origin subgroups. Inequities in flood risk exposure are statistically analyzed using socio-demographic variables derived from the 2010 U.S. Census and 2007-2011 American Community Survey estimates, and 100-year flood risk zones from the Federal Emergency Management Agency (FEMA). Social vulnerability is represented with two neighborhood deprivation indices called economic insecurity and instability. We also analyze the presence of seasonal/vacation homes and proximity to public beach access sites as water-related amenity variables. Logistic regression modeling is utilized to estimate the odds of neighborhood-level exposure to coastal and inland 100-year flood risks. Results indicate that neighborhoods with greater percentages of non-Hispanic Blacks, Hispanics, and Hispanic subgroups of Colombians and Puerto Ricans are exposed to inland flood risks in areas without water-related amenities, while Mexicans are inequitably exposed to coastal flood risks. Our findings demonstrate the importance of treating coastal and inland flood risks separately while controlling for water-related amenities, and

    Hydrogeologic characterization of karst limestone aquifers is difficult due to the variability in the spatial distribution of porosity and dissolution features. Typical methods for aquifer investigation, such as drilling and pump testing, are limited by the scale or spatial extent of the measurement. Hydrogeophysical techniques such as ground penetrating radar (GPR) can provide indirect measurements of aquifer properties and be expanded spatially beyond typical point measures. This investigation used a multiscale approach to identify and quantify porosity distribution in the Miami Limestone, the lithostratigraphic unit that composes the uppermost portions of the Biscayne Aquifer in Miami Dade County, Florida. At the meter scale, laboratory measures of porosity and dielectric permittivity were made on blocks of Miami Limestone using zero offset GPR, laboratory and digital image techniques. Results show good correspondence between GPR and analytical porosity estimates and show variability between 22 and 66 %. GPR measurements at the field scale 10-1000 m investigated the bulk porosity of the limestone based on the assumption that a directly measured water table would remain at a consistent depth in the GPR reflection record. Porosity variability determined from the changes in the depth to water table resulted in porosity values that ranged from 33 to 61 %, with the greatest porosity variability being attributed to the presence of dissolution features. At the larger field scales, 100 - 1000 m, fitting of hyperbolic diffractions in GPR common offsets determined the vertical and horizontal variability of porosity in the saturated subsurface. Results indicate that porosity can vary between 23 and 41 %, and delineate potential areas of enhanced recharge or groundwater / surface water interactions. This study shows porosity variability in the Miami Limestone can range from 22 to 66 % within 1.5 m distances, with areas of high macroporosity or karst dissolution features

    2005-01-01

    The Great Miami River Buried Valley Aquifer System is one of the most productive sources of potable water in the Midwest, yielding as much as 3,000 gallons per minute to wells. Many water-supply wells tapping this aquifer system are purposely placed near rivers to take advantage of induced infiltration from the rivers. The City of Hamilton's North Well Field consists of 10 wells near the Great Miami River, all completed in the lower Great Miami River Buried Valley Aquifer System. A well-drilling program and a multiple-well aquifer test were done to investigate ground-water flow directions and to estimate aquifer hydraulic properties in the lower part of the Great Miami River Buried Valley Aquifer System. Descriptions of lithology from 10 well borings indicate varying amounts and thickness of clay or till, and therefore, varying levels of potential aquifer confinement. Borings also indicate that the aquifer properties can change dramatically over relatively short distances. Grain-size analyses indicate an average bulk hydraulic conductivity value of aquifer materials of 240 feet per day; the geometric mean of hydraulic conductivity values of aquifer material was 89 feet per day. Median grain sizes of aquifer material and clay units were 1.3 millimeters and 0.1 millimeters, respectively. Water levels in the Hamilton North Well Field are affected by stream stage in the Great Miami River and barometric pressure. Bank storage in response to stream stage is evident. Results from a multiple-well aquifer test at the well field indicate, as do the lithologic descriptions, that the aquifer is semiconfined in some areas and unconfined in others. Transmissivity and storage coefficient of the semiconfined part of the aquifer were 50,000 feet squared per day and 5x10-4, respectively. The average hydraulic conductivity (450 feet per day) based on the aquifer test is reasonable for glacial outwash but is higher than calculated from grain-size analyses, implying a scale effect

    Research examining the determinants of fear of crime has arguably raised more questions than it has answered. This exploratory study addresses one of the compelling questions that remains unanswered: what is the role of ethnicity, both at the community and individual levels, in understanding variation in fear of crime? Guided by racial or minority group threat theory, we examine the relative sizes of both the Black and Latino populations as indicators of minority group threat to determine their role in understanding individual fear of crime in a city where Latinos represent a much larger proportion of the population than Blacks (Miami-Dade County, Florida). Furthermore, the race and ethnic backgrounds of the respondents are also considered to evaluate their role in understanding variation in the fear of crime. Using both Census tract-level data and data collected from a NIDA sponsored grant that was part of a larger study about physically disabled residents, our findings reveal that in Miami-Dade County where Blacks are highly segregated from whites, the relative size of the Latino population is a predictor of fear of crime among white residents. Implications of this finding are considered, including a call for more nuanced research focusing on the predictors of fear of crime within multiethnic communities. PMID:19227693

  1. Helicopter electromagnetic survey of the Model Land Area, Southeastern Miami-Dade County, Florida

    2012-01-01

    This report describes a helicopter electromagnetic survey flown over the Model Land Area in southeastern Miami-Dade County, Florida, to map saltwater intrusion in the Biscayne aquifer. The survey, which is located south and east of Florida City, Florida, covers an area of 115 square kilometers with a flight-line spacing of 400 meters. A five-frequency, horizontal, coplanar bird with frequencies ranging from 400 to 100,000 Hertz was used. The data were interpreted using differential resistivity analysis and inversion to produce cross sections and resistivity depth-slice maps. The depth of investigation is as deep as 100 meters in freshwater-saturated portions of the Biscayne aquifer and the depth diminishes to about 50 meters in areas that are intruded by saltwater. The results compare favorably with ground-based, time-domain electromagnetic soundings and induction logs from observation wells in the area. The base of a high-resistivity, freshwater-saturated zone mapped in the northern 2 kilometers of the survey area corresponds quite well with the base of the surficial aquifer that has been determined by drilling. In general, saltwater in the survey area extends 9 to 12 kilometers inland from the coast; however, there is a long nose of saltwater centered along the Card Sound Road Canal that extends 15 kilometers inland. The cause of this preferential intrusion is likely due to uncontrolled surface flow along the canal and subsequent leakage of saltwater into the aquifer. Saltwater also extends farther inland in the area between U.S. Highway 1 and Card Sound Road than it does to the west of this area. Until 1944, a railroad grade occupied the current location of U.S. Highway 1. Borrow ditches associated with the railroad grade connected to Barnes Sound and allowed saltwater to flow during droughts and storm surges to within a few kilometers of Florida City. Relicts of this saltwater that settled to the bottom of the Biscayne aquifer can be seen in the helicopter

  2. Fluid inclusions in vadose cement with consistent vapor to liquid ratios, Pleistocene Miami Limestone, southeastern Florida

    1988-01-01

    Vadose cements in the Late Pleistocene Miami Limestone contain regions with two-phase aqueous fluid inclusions that have consistent vapor to liquid (V-L) ratios. When heated, these seemingly primary inclusions homogenize to a liquid phase in a range between 75??C and 130??C (mean = 100??C) and have final melting temperatures between -0.3?? and 0.0??C. The original distribution of Th was broadened during measurements because of fluid inclusion reequilibration. The narrow range of Th in these fluid inclusions suggest unusually consistent V-L ratios. They occur with small, obscure, single phase liquid-filled inclusions, which infer a low temperature origin (less than 60??C), and contradict the higher temperature origin implied by the two phase inclusions. The diagenetic environment producing these seemingly primary fluid inclusions can be inferred from the origin of the host calcite enclosing them. The ??18O composition of these cements (-4 to-5.5%., PDB) and the fresh water in the fluid inclusions are consistent with precipitation from low-temperature meteoric water. The carbon-isotope composition of the vadose cements that contain only rare two-phase fluid inclusions are comparable to the host rock matrix (??13C between 0 and +4%., PDB). Cements that contain common two-phase fluid-inclusions have a distinctly lighter carbon isotopic composition of -3 to -5%.. The carbon isotope composition of cements that contain common two-phase inclusions are about 6%. lighter than those of other vadose cements; models of early meteoric diagenesis indicate that this is the result of precipitation from water that has been influenced by soil gas CO2. Our hypothesis is that the primary fluid inclusions, those with consistent V-L ratios and the single-phase liquid inclusions, form at near-surface temperature (25??C) and pressure when consistent proportions of soil gas and meteoric water percolating through the vadose zone are trapped within elongate vacuoles. This study corroborates

    cherts on both Admiralty and Kupreanof Islands contain radiolarians as young as Permian, the age of the Cannery Formation is herein extended to Late Devonian through early Permian, to include the early Permian rocks exposed in its type locality. The Cannery Formation is folded and faulted, and its stratigraphic thickness is unknown but inferred to be several hundred meters. The Cannery Formation represents an extended period of marine deposition in moderately deep water, with slow rates of deposition and limited clastic input during Devonian through Pennsylvanian time and increasing argillaceous, volcaniclastic, and bioclastic input during the Permian. The Cannery Formation comprises upper Paleozoic rocks in the Alexander terrane of southeastern Alaska. In the pre-Permian upper Paleozoic, the tectonic setting of the Alexander terrane consisted of two or more evolved oceanic arcs. The lower Permian section is represented by a distinctive suite of rocks in the Alexander terrane, which includes sedimentary and volcanic rocks containing early Permian fossils, metamorphosed rocks with early Permian cooling ages, and intrusive rocks with early Permian cooling ages, that form discrete northwest-trending belts. After restoration of 180 km of dextral displacement of the Chilkat-Chichagof block on the Chatham Strait Fault, these belts consist, from northeast to southwest, of (1) bedded chert, siliceous argillite, volcaniclastic turbidites, pillow basalt, and limestone of the Cannery Formation and the Porcupine Slate of Gilbert and others (1987); (2) greenschist-facies Paleozoic metasedimentary and metavolcanic rocks that have Permian cooling ages; (3) silty limestone and calcareous argillite interbedded with pillow basalt and volcaniclastic rocks of the Halleck Formation and the William Henry Bay area; and (4) intermediate-composition and syenitic plutons. These belts correspond to components of an accretionary complex, contemporary metamorphic rocks, forearc-basin deposits,

    Streambed-sediment and fish-tissue samples were collected at eight sites in the Great and Little Miami Basins as part of the U.S. Geological Survey's National Water Quality Assessment Program. The samples were analyzed for trace elements and synthetic organic compounds, including organochlorine insecticides, polychlorinated biphenyls (PCBs), and semivolatile compounds (SVOCs). Data from state-agency investigations within the study unit (more than 200 sites) were incorporated to gain a broader perspective of the occurrence and distribution of contaminants in the study unit. All data were compared to streambed-sediment-quality guidelines and fish-tissue guidelines to identify elevated contaminant concentrations. Guideline exceedances were plotted on distribution maps to identify areas in the study unit that may be of potential concern for wildlife health. Several trace elements were detected in both sediment and fish-tissue samples. In sediment, lead and zinc were most frequently detected at levels that may have adverse effects on aquatic organisms. Generally, only one of the trace elements analyzed for per site exceeded concentrations above which adverse biological effects are frequently anticipated. Organochlorine insecticides were infrequently detected in sediment or fish tissue throughout the study unit. More organochlorine insecticides were detected in fish tissues than in sediment; however, more guidelines were exceeded in sediment. No distinct geographic overlap between sediment and fish-tissue sites was evident with respect to elevated organochlorine insecticide concentrations. Sediment-quality guideline exceedances were generally widespread throughout the study unit, whereas fish-tissue guidelines were exceeded only on the Mad River. PCBs were detected more often in fish tissue than in sediment throughout the study unit. Elevated PCB concentrations in fish tissue were common and widespread. No distinct geographic overlap of PCB exceedances was evident

    1992-01-01

    The efforts toward realistic vortex modeling for rotary wings which began under the guidance of professor A. A. Nikolsky of Princeton University in 1955-1956 are discussed. Attention is given to Nikolsky's flow-visualization studies and major theoretical considerations for vortex modeling. More recent efforts by other researchers have led to models of increasing complexity. The neglect of compressibility and viscous effects in the classical approach is noted to be a major limiting factor in full-scale rotor applications of the classical vortex theory; it has nevertheless been valuable for the delineation of problem areas and the guiding of both experimental and theoretical investigations.

    An increased demand for fresh groundwater resources in South Florida has prompted Miami-Dade County to expand its water reclamation program and actively pursue reuse plans for aquifer recharge, irrigation, and wetland rehydration. The U.S. Geological Survey, in cooperation with the Miami-Dade Water and Sewer Department (WASD) and the Miami-Dade Department of Environmental Resources Management (DERM), initiated a study in 2008 to assess the presence of selected pharmaceuticals and other organic wastewater compounds in the influent and effluent at three regional wastewater-treatment plants (WWTPs) operated by the WASD and at one WWTP operated by the City of Homestead, Florida (HSWWTP).

    The current study utilizes the recently curated and databased Alexander Grasshopper Collection coupled with a new resurvey program to measure the effects of climate change on grasshoppers found along an elevational gradient in the southern Rocky Mountains of Colorado. The Alexander Collection is composed of approximately 19,000 pinned grasshoppers and a series of field data notebooks from a three year 1958-1960 survey project. During these survey years, Alexander processed over 65,000 grasshoppers from repeatedly sampled sites along an elevational gradient from Boulder (1530 m elev.) to Mt Evans (3900m elev.) in the Colorado Front Range. Data from 2006 shows that at mid-elevation sites grasshoppers are becoming adults 15-28 days earlier than they did nearly a half century ago. We found no changes in the time to reach adulthood at the high elevation sites. Preliminary data from 2007 (a year with milder spring temperatures) suggests that unlike the dramatic patterns documented in 2006, that the time to reach adulthood for grasshoppers at low and high elevation sites was not much different than it was 50 years ago. In 2007, several grasshopper species at mid-elevation did become adults earlier than they had a half century ago.

    During the 1790s, Alexander von Humboldt (1769-1859), who showed an early interest in many facets of natural philosophy and natural history, delved into the controversial subject of galvanism and animal electricity, hoping to shed light on the basic nature of the nerve force. He was motivated by his broad worldview, the experiments of Luigi Galvani, who favored animal electricity in more than a few specialized fishes, and the thinking of Alessandro Volta, who accepted specialized fish electricity but was not willing to generalize to other animals, thinking Galvani's frog experiments flawed by his use of metals. Differing from many German Naturphilosophen, who shunned "violent" experiments, the newest instruments, and detailed measurement, Humboldt conducted thousands of galvanic experiments on animals and animal parts, as well as many on his own body, some of which caused him great pain. He interpreted his results as supporting some but not all of the claims made by both Galvani and Volta. Notably, because of certain negative findings and phenomenological differences, he remained skeptical about the intrinsic animal force being qualitatively identical to true electricity. Hence, he referred to a "galvanic force," not animal electricity, in his letters and publications, a theoretical position he would abandon with Volta's help early in the new century.

  20. Deficits in Adult Neurogenesis, Contextual Fear Conditioning, and Spatial Learning in a Gfap Mutant Mouse Model of Alexander Disease

    Glial fibrillary acidic protein (GFAP) is the major intermediate filament of mature astrocytes in the mammalian CNS. Dominant gain of function mutations in GFAP lead to the fatal neurodegenerative disorder, Alexander disease (AxD), which is characterized by cytoplasmic protein aggregates known as Rosenthal fibers along with variable degrees of leukodystrophy and intellectual disability. The mechanisms by which mutant GFAP leads to these pleiotropic effects are unknown. In addition to astrocytes, GFAP is also expressed in other cell types, particularly neural stem cells that form the reservoir supporting adult neurogenesis in the hippocampal dentate gyrus and subventricular zone of the lateral ventricles. Here, we show that mouse models of AxD exhibit significant pathology in GFAP-positive radial glia-like cells in the dentate gyrus, and suffer from deficits in adult neurogenesis. In addition, they display impairments in contextual learning and spatial memory. This is the first demonstration of cognitive phenotypes in a model of primary astrocyte disease. PMID:24259590

    This article presents results from a mixed-method evaluation of a structured cooking and gardening program in Australian primary schools, focusing on program impacts on the social and learning environment of the school. In particular, we address the Stephanie Alexander Kitchen Garden Program objective of providing a pleasurable experience that has a positive impact on student engagement, social connections, and confidence within and beyond the school gates. Primary evidence for the research question came from qualitative data collected from students, parents, teachers, volunteers, school principals, and specialist staff through interviews, focus groups, and participant observations. This was supported by analyses of quantitative data on child quality of life, cooperative behaviors, teacher perceptions of the school environment, and school-level educational outcome and absenteeism data. Results showed that some of the program attributes valued most highly by study participants included increased student engagement and confidence, opportunities for experiential and integrated learning, teamwork, building social skills, and connections and links between schools and their communities. In this analysis, quantitative findings failed to support findings from the primary analysis. Limitations as well as benefits of a mixed-methods approach to evaluation of complex community interventions are discussed.

    The Jabirian Corpus refers to the K. Thahirat Al-'Iskandar, "The Book of the Treasure of Alexander" (hereafter BTA), as one of several forgeries suggesting that alchemical secrets were hidden in inscriptions in various places. The book was neglected until 1926, when Julius Ruska discussed it in his work on the Emerald Tablet, placing the BTA within the literature related to the development of Arabic alchemy. His preliminary study became an essential reference and encouraged many scholars to work on the BTA in the following decades. Some years ago, we completed the first translation of the BTA into a Western language. The work was based on the acephalous Escorial manuscript, which we identified as a fourteenth-century copy of the BTA. This manuscript is peculiar, as part of it is encoded. After finishing our translation, we started to establish the text of the BTA. At present, the text is in process of fixation--to be followed by textual criticism--and has been the main focus of a thorough study of ours on medieval hermeticism and alchemy. A sample of the work currently in progress is presented in this paper: an analysis of the variations between different manuscripts along with a study and English translation of its alchemical chapter.

  4. Methods to quantify seepage beneath Levee 30, Miami-Dade County, Florida

    A two-dimensional, cross-sectional, finite-difference, ground-water flow model and a simple application of Darcy?s law were used to quantify ground-water flow (from a wetlands) beneath Levee 30 in Miami-Dade County, Florida. Geologic and geophysical data, vertical seepage data from the wetlands, canal discharge data, ground-water-level data, and surface-water-stage data collected during 1995 and 1996 were used as boundary conditions and calibration data for the ground-water flow model and as input for the analytical model. Vertical seepage data indicated that water from the wetlands infiltrated the subsurface, near Levee 30, at rates ranging from 0.033 to 0.266 foot per day when the gates at the control structures along Levee 30 canal were closed. During the same period, stage differences between the wetlands (Water Conservation Area 3B) and Levee 30 canal ranged from 0.11 to 1.27 feet. A layer of low-permeability limestone, located 7 to 10 feet below land surface, restricts vertical flow between the surface water in the wetlands and the ground water. Based on measured water-level data, ground-water flow appears to be generally horizontal, except in the direct vicinity of the canal. The increase in discharge rate along a 2-mile reach of the Levee 30 canal ranged from 9 to 30 cubic feet per second per mile and can be attributed primarily to ground-water inflow. Flow rates in Levee 30 canal were greatest when the gates at the control structures were open. The ground-water flow model data were compared with the measured ground-water heads and vertical seepage from the wetlands. Estimating the horizontal ground-water flow rate beneath Levee 30 was difficult owing to the uncertainty in the horizontal hydraulic conductivity of the main flow zone of the Biscayne aquifer. Measurements of ground-water flows into Levee 30 canal, a substantial component of the water budget, were also uncertain, which lessened the ability to validate the model results.

    Subtle ``instrumentation" is often unnoticed. Stone-chamber transponder-receivers are principle and secondary wave detectors, part of the ``technologic" arsenal of men like Passaconaway/Metacomen of colonial-era Massachusetts, or the earthquake-predicting Shawnee Tecumseh of the Ohio Valley region, during 1811-1813. An Ohio stone-effigy ``serpent" is a thunderstorm precursor signal indicator. The Hopi require similar ``equipment," when duping gullible ``rain-dance" patrons. Tornado/waterspout activity is documented right in the Tequesta site at the river in Miami, Florida, which generates detectable signals. Columbus could have used similar ``secret sacred science" previously learned from American Indians, and thereby successfully predicted an anomalous hurricane on a subsequent trip. These, and the Hawaiian volcano goddess Pelee, seem to be a mythic equivalent of electromagnetically generated signals, i.e., a metaphor for ``environmental applied physics" we detect at A.S.

    Florida purchased the Tequesta ([Langue] doc Christ Spirit-signal) Indian site along the Miami River site that vigorously pulsates with even minor rainstorms entering or leaving the area. Although there is a laughable chimera of a fountain of youth associated with Ponce de Leons discovery of the Florida peninsula in about AD 1513, the Calusa (Royal Christ Jesus Spirit-signal) Indian Nation has an associated significance with EMF signals they possibly monitored throughout their area of activity. Our efforts have also led to the investigation of cultural and other influences implied by the Matacumbe Keys that indicate a shared commonality of awareness with Native Americans of the northeast such as Metacomet, or regions like Maines Grand Lake Matagamon and its associated electromagnetic Spirit Signal. Wikiwa Springs near Orlando shares much with Massachusetts (adherent of serpent Jesus Christ Spirit-signal) Natick, and New Hampshires Naticook Island. These are the locales of environmentally sensitive instrumentation.

    The objective of this project was to test the ability of the Miami Isopycnic-Coordinate Ocean Model (MICOM) to simulate the global ocean circulation, setting the stage for the model's incorporation into coupled global climate models. An existing basin-scale model will be expanded to global domain; suitable atmospheric forcing fields, including precipitation and river runoff, will be selected; the modeling of ayssal flow will be improved by incorporating compressibility and particularly thermobaric effects; a sea-ice model will be added; parameterization options will be explored for subgrid-scale deep convection; parallel coarse- and fine-mesh simulations will be carried out to investigate the impact of grid resolution; the sensitivity of the model's solution to magnitude of vertical (diapycnal) exchange coefficient will be studied; and long-term trends in meridional heat transport and water-mass properties in model solutions will be documented and interpreted.

    Four popular, recreational beaches in Miami, FL are Hobie Beach, Virginia Key Beach, Crandon Park Beach, and Bill Baggs Cape Florida State Park. While all of the beaches are within a few miles of each other in Biscayne Bay, they have greatly differing water qualities, as determined by the testing for fecal indicator bacteria performed by the Florida Department of Health. Using the geodesic theory of transport barriers, we identify Lagrangian Coherent Structures (LCSs) in each area. We show how these material curves, which shape circulation and mixing patterns, can be used to explain the incongruous states of the water at beaches that should be comparable. The LCSs are computed using a hydrodynamic model and verified through field experimentation at each beach.

    The Munisport Landfill site is an inactive landfill in, and owned by, the City of North Miami, Florida. The site is an urban area adjacent to the Oleta River Recreational Area, a state mangrove preserve, and Biscayne Bay. Soil, sediments, surface water, and ground water are contaminated. The authors selected ammonia, benzene, di(2-ethylhexyl)phthalate, cadmium, carbon disulfide, chloromethane, coliform bacteria, dieldrin, lead, methylene chloride, pentachlorophenol, polychlorinated biphenyls (PCBs), styrene, vanadium, and zinc as contaminants of concern. Accidentally ingesting contaminated soil and surface water, and breathing contaminated smoke are completed human exposure pathways. Children who swam in the landfill lakes risked bacterial and viral infections. Based on the available data, the authors categorize the Munisport Landfill site as an indeterminate public health hazard.

    In 1998, 25 samples of ground water from the Lockport Dolomite in western Ohio were analyzed for major ions, trace elements, and arsenic. Samples were collected from residential wells in Darke, Miami, Montgomery, and Preble Counties. The water sampled was untreated, except perhaps for water from one well. In general, samples from the northern part of the study area had the highest concentrations of common constituents such as calcium, magnesium, potassium, sulfate, boron, and strontium. Iron and strontium concentrations were generally high throughout the study area, with median concentrations of 4,500 ?g/L (micrograms per liter) and 1,500 ?g/L, respectively. Arsenic concentrations, which ranged from less than 1 ?g/L to 29 ?g/L, did not exceed the drink ing-water standard of 50 ?g/L.

    Expansion of mosquito-borne pathogens into more temperate regions of the world necessitates tools such as mathematical models for understanding the factors that contribute to the introduction and emergence of a disease in populations naïve to the disease. Often, these models are not developed and analyzed until after a pathogen is detected in a population. In this study, we develop a spatially explicit stochastic model parameterized with publicly available U.S. Census data for studying the potential for disease spread in Urbanized Areas of the United States. To illustrate the utility of the model, we specifically study the potential for introductions of dengue to lead to autochthonous transmission and outbreaks in a population representative of the Miami Urbanized Area, where introductions of dengue have occurred frequently in recent years. We describe seasonal fluctuations in mosquito populations by fitting a population model to trap data provided by the Miami-Dade Mosquito Control Division. We show that the timing and location of introduced cases could play an important role in determining both the probability that local transmission occurs as well as the total number of cases throughout the entire region following introduction. We show that at low rates of clinical presentation, small outbreaks of dengue could go completely undetected during a season, which may confound mitigation efforts that rely upon detection. We discuss the sensitivity of the model to several critical parameter values that are currently poorly characterized and motivate the collection of additional data to strengthen the predictive power of this and similar models. Finally, we emphasize the utility of the general structure of this model in studying mosquito-borne diseases such as chikungunya and Zika virus in other regions. PMID:27532496

    After extensive experimentation during the 1790s, Alexander von Humboldt remained skeptical about "animal electricity" (and metallic electricity), writing instead about an ill-defined galvanic force. With his worldview and wishing to learn more, he studied electric eels in South America just as the new century began, again using his body as a scientific instrument in many of his experiments. As had been the case in the past and for many of the same reasons, some of his findings with the electric eel (and soon after, Italian torpedoes) seemed to argue against biological electricity. But he no longer used galvanic terminology when describing his electric fish experiments. The fact that he now wrote about animal electricity rather than a different "galvanic" force owed much to Alessandro Volta, who had come forth with his "pile" (battery) for multipling the physical and perceptable effects of otherwise weak electricity in 1800, while Humboldt was deep in South America. Humboldt probably read about and saw voltaic batteries in the United States in 1804, but the time he spent with Volta in 1805 was probably more significant in his conversion from a galvanic to an electrical framework for understanding nerve and muscle physiology. Although he did not continue his animal electricity research program after this time, Humboldt retained his worldview of a unified nature and continued to believe in intrinsic animal electricity. He also served as a patron to some of the most important figures in the new field of electrophysiology (e.g., Hermann Helmholtz and Emil du Bois-Reymond), helping to take the research that he had participated in to the next level.

Log-Pearson Type III distributions were fit to annual peak flow values for the period 1921 or 1922 through 2007 (the most recent year of published peak flow values at the time of this analysis) and annual peak dam-pool storage values for the period 1922- 2008 to determine peaks with recurrence intervals of 2, 5, 10, 25, 50, 100, 200, and 500 years. Once storages had been estimated for the various recurrence intervals, corresponding dam-pool elevations were determined from elevation-storage ratings provided by the Miami Conservancy District.

  20. Einstein's conversion from his static to an expanding universe

    NASA Astrophysics Data System (ADS)

    Nussbaumer, Harry

    2014-02-01

    In 1917 Einstein initiated modern cosmology by postulating, based on general relativity, a homogenous, static, spatially curved universe. To counteract gravitational contraction he introduced the cosmological constant. In 1922 Alexander Friedman showed that Albert Einstein's fundamental equations also allow dynamical worlds, and in 1927 Georges Lemaître, backed by observational evidence, concluded that our universe was expanding. Einstein impetuously rejected Friedman's as well as Lemaître's findings. However, in 1931 he retracted his former static model in favour of a dynamic solution. This investigation follows Einstein on his hesitating path from a static to the expanding universe. Contrary to an often advocated belief the primary motive for his switch was not observational evidence, but the realisation that his static model was unstable.

    Subsurface water flow in South Florida is largely controlled by the heterogeneous nature of the karst limestone in the Biscayne aquifer and its upper formation, the Miami Limestone. These heterogeneities are amplified by dissolution structures that induce changes in the aquifer's material and physical properties (i.e., porosity and dielectric permittivity) and create preferential flow paths. Understanding such patterns are critical for the development of realistic groundwater flow models, particularly in the Everglades, where restoration of hydrological conditions is intended. In this work, we used noninvasive ground penetrating radar (GPR) to estimate the spatial variability in porosity and the dielectric permittivity of the solid phase of the limestone at centimeter-scale resolution to evaluate the potential for field-based GPR studies. A laboratory setup that included high-frequency GPR measurements under completely unsaturated and saturated conditions was used to estimate changes in electromagnetic wave velocity through Miami Limestone samples. The Complex Refractive Index Model was used to derive estimates of porosity and dielectric permittivity of the solid phase of the limestone. Porosity estimates of the samples ranged between 45.2 and 66.0% and showed good correspondence with estimates of porosity using analytical and digital image techniques. Solid dielectric permittivity values ranged between 7.0 and 13.0. This study shows the ability of GPR to image the spatial variability of porosity and dielectric permittivity in the Miami Limestone and shows potential for expanding these results to larger scales and other karst aquifers.

    I believe that the transient blindness which presented Alexander the Great after his being wounded on his head and/or his neck by a stone from a catapult during the siege of Cyropolis (329 BC) was in all probability a case of transient cortical blindness that was recognized as a special entity in the 1960s. I reached this conclusion after the comparative study of the Emperor's clinical picture provided by ancient texts, especially those of Plutarch and Quintus Curtius Rufus, with that of a modern medical bibliography.

    This study describes the rates of HIV, HBV, and HCV seropositivity among drug-involved, female street sex workers in low-income, inner-city sections of Miami, Florida; further, their sociodemographic characteristics, drug use, and sexual risk behaviors were assessed; and predictors of infection were reported. A sample of 586 sex workers was recruited through targeted sampling methods, interviewed, and counseled and tested for the presence of antibody to HIV, HBV, and HCV. Respondents' median age was 38 years, median time in sex work was 14 years, all were heavily involved in the use of alcohol and drugs, and 42% were homeless. More than half (51.0%) had engaged in unprotected vaginal sex in the past month. Prevalences were HIV, 22.4%; HBV, 53.4%; HCV, 29.7%. A multidimensional public health program must address not only issues related to unsafe sex, but also the problems of drug abuse, homelessness, and other lifestyle factors that contribute to risk behaviors.

    Pregnant women and infants are two groups at the highest risk of severe outcomes from foodborne illnesses. We surveyed adult clients of a Women, Infants, and Children (WIC) clinic serving predominately African Americans in inner-city Miami, Florida, to assess food safety practices. Eligible and consenting women completed a 23-item self-administered survey with questions concerning food handling practices around the Partnership for Food Safety Education's Fight BAC! campaign constructs of "clean", "separate" (not cross-contaminated), "cook", and "chill". Of 342 eligible clients, 299 (87.4%) consented to participate. In general, the clients' food safety practices were most problematic in the cook and chill constructs. Using a cooking thermometer, refrigerating foods within 2 h, and thawing them safely were the least commonly reported safe practices. Women who were pregnant with their first child had the lowest food safety practice scores. Of the 62 pregnant participants, 32 (51.6%) reported eating hot dogs or deli meats without first reheating them some of the time or more often, and 22 (35.5%) reported eating soft cheeses and blue-veined cheeses some of the time or more often, putting the women at risk of listeriosis. Although all women in the WIC program could benefit from food safety education, these findings indicate that women during their first pregnancy should especially be targeted for food safety education.

    Street-based female sex workers constitute a vulnerable population for HIV, as they are often enmeshed in chronic patterns of substance use, sexual risk, homelessness, and violent victimization. This study examined the specific contributions of victimization history and abuse-related traumagenic factors to mental health functioning and sexual risk behaviors, while considering the impact of environmental risk factors as well. Using targeted sampling strategies, we enrolled 562 Miami-based female sex workers into an intervention trial testing the relative effectiveness of two alternative case management conditions in establishing linkages with health services and reducing risk for HIV. Lifetime prevalence of abuse was extremely elevated at 88%. Nearly half reported abuse before the age of 18, while 34% reported violent encounters with "dates" or clients in the past 90 days. Serious mental illness (SMI) was quite common, with 74% reporting severe symptoms of depression, anxiety, or traumatic stress. For those with histories of abuse, SMI appeared to mediate the association between abuse-related trauma and unprotected sex behaviors. Mental health treatment would appear to be an important component of effective HIV prevention among this vulnerable group, and should form part of a compendium of services offered to female sex workers.

    This paper evaluates the efficacy the Moss-Miami System instrumentation for surgical treatment of spinal deformity. Eight-five patients with AIS underwent a posterior spinal fusion with using this system between 1994 and 1998. Radiographs of the spine were taken preoperatively, at discharge, one year after surgery, and at the latest follow-up (average of 2.5 year, range 2 to 6 years). All radiographs were assessed for curve magnitude, coronal balance, kyphosis, lordosis, junctional kyphosis, and sagittal balance. The scoliosis research society instrument was administered at the final follow-up. the average curve correction ranged from 53 to 65 percent. All patients showed solid fusion by final follow-up. three patients required a second operation for complications related to their scoliosis; two patients showed a rod fracture without evidence of pseudoarthrosis or curve progression. Two transient neurological complications related to the surgery were observed. SRS results were favorable with regard to function and cosmetic appearance. PMID:17907427

    Cervical cancer disproportionately affects minorities, immigrants and low-income women in the USA, with disparities greatest among Latino immigrants. We examined barriers and facilitators to cervical cancer screening practices among a group of immigrant Latino women in Florida, USA. Between January and May 2013, six focus group discussions, involving 35 participants, were conducted among Hispanic women in Miami to explore their knowledge, beliefs about cervical cancer and facilitators and barriers to cervical cancer screening using a theoretical framework. The data showed that family support, especially from female relatives, was an important facilitator of screening and treatment. Women, however, reported prioritising family health over their own, and some expressed fatalistic beliefs about cancer. Major obstacles to receiving a Pap smear included fear that it might result in removal of the uterus, discomfort about being seen by a male doctor and concern that testing might stigmatise them as being sexually promiscuous or having a sexually transmitted disease. Targeted education on cancer and prevention is critically needed in this population. Efforts should focus on women of all ages since younger women often turn to older female relatives for advice.

    Although homelessness has frequently been associated with substance abuse, and has been established as a predictor of HIV risk among substance abusers, little is known about the impact of homelessness on HIV risk among female sex workers. This analysis investigated the contribution of homelessness to sexual risk taking among a sample of 485 female sex workers recruited into an HIV prevention programme in Miami, Florida, 41.6% of whom considered themselves to be currently homeless. Findings indicated that in comparison to non-homeless sex workers, significantly more homeless sex workers were daily users of alcohol and crack, and their past month sex work reflected significantly more frequent vaginal and oral sex acts, higher levels of unprotected vaginal sex and more numerous sexual activities while 'high' on drugs. At the same time, a significantly greater proportion of homeless sex workers encountered customers that refused to use condoms than did the non-homeless sex workers. There were no significant differences in HIV seropositivity between the homeless and non-homeless women (22.5 and 24.9%, respectively), primarily because the majority of the women in the study cycled in and out of homelessness.

    Recent field studies to clarify stratigraphic relationships between the Elkahatchee Quartz Diorite Gneiss and the Brevard zone lead to the interpretation that part of the Emuckfaw Group is correlative with, and probably structurally continuous with, part of the Wedowee Group. The Josie Leg formation of Bieler and Deininger (1987) is a sequence of metagraywackes and interbedded metapelites; it is here interpreted as a coarse submarine fan facies. The northwestern contact of the unit, frequently mapped as the Alexander City fault, maps into the Wadley Line in the New Site and Daviston quadrangles. The southeastern contact is a sheared contact with structurally overlying migmatitic rocks that include quartzites and calcsilicates. The Josie Leg and Wedowee rocks form a southwesterly plunging synform in which the Elkahatchee lies. Where the contact between the units is gently dipping it is mapped as the Wadley line. Where the contact has been folded and dips steeply, it is highly sheared and is mapped as the Alexander City fault. It is impossible to determine at this time how much the section has been attenuated during the shearing. Although the contact has been interpreted as structural, the data are not unambiguous. The Josie Leg/Wedowee contact may be a stratigraphic contact with the apparent structural discordance reflecting the different mechanical behavior of the contrasting lithologies.

    Background Type 2 diabetes mellitus disproportionately affects the Latino community. Latinos with diabetes are also less likely to have adequate control of cardiovascular risk factors such as cholesterol and blood pressure. Community health workers (CHWs) are increasingly being used to address various health disparity conditions, including diabetes. However, evidence of their effectiveness from randomized controlled trials is limited. Methods The Miami Health Heart Initiative is a randomized controlled trial of 300 Latino patients with diabetes. Patients with hemoglobin A1c (HbA1c) ≥8.0% were recruited from Miami-Dade’s public hospital system. At baseline, all patients underwent phlebotomy, physical examination, and a structured 90-minute research interview. They were then randomized to either usual care or a CHW intervention called Cariño. For participants in the Cariño arm of the study, CHW services included assistance with nonmedical social services, health education, and patient navigation in which the CHWs serve as a bridge between patients and the health care system. These services were delivered through home visits, phone calls, and group visits. At 12 months, all subjects had a follow-up examination. The primary outcomes at 1 year are changes in systolic blood pressure, low-density lipoprotein, and HbA1c. Secondary outcomes include medication adherence, medication intensification, diabetes self-efficacy, physical activity, and self-reported fruit and vegetable intake. Discussion The Miami Healthy Heart Initiative is one of the first rigorously conducted randomized controlled trials to provide evidence on the impact of CHWs on diabetes intermediate outcomes among Latinos. If the data support our primary hypotheses, the study would lend added support to ongoing efforts to incorporate CHWs as part of our national efforts to reduce and ultimately eliminate health disparities.

    Biscayne Bay is an oligotrophic, subtropical estuary located along the southeastern coast of Florida that provides habitat for a variety of plant and animal life. Concern has arisen with regard to the ecological health of Biscayne Bay because of the presence of nutrient-laden discharges from the east coast canals that drain into the bay. This concern, as well as planned diversion of discharges for ecosystem restoration from the urban and agricultural corridors of Miami-Dade County to Everglades National Park, served as the impetus for a study conducted during the 1996 and 1997 water years to estimate nutrient loads discharged from the east coast canals into Biscayne Bay. Analytical results indicated that the highest concentration of any individual nutrient sampled for in the study was 4.38 mg/L (milligrams per liter) for nitrate at one site, and the lowest concentrations determined were below the detection limits for orthophosphate at six sites and nitrite at four sites. Median concentrations for all the sites were 0.75 mg/L for total organic nitrogen, 0.10 mg/L for ammonia, 0.02 mg/L for nitrite, 0.18 mg/L for nitrate, 0.20 mg/L for nitrite plus nitrate nitrogen, 0.02 mg/L for total phosphorus, and 0.005 mg/L for orthophosphate. The maximum total phosphorus concentration of 0.31 mg/L was the only nutrient concentration to exceed U.S. Environmental Protection Agency (1986) water-quality criteria. High concentrations of total phosphorus usually reflect contamination as a result of human activities. Five sites exceeded the fresh-water quality standard of 0.5 mg/L for ammonia concentration as determined by the Miami-Dade County Department of Environmental Resources Management. Median total organic nitrogen concentrations were higher in urban and forested/wetland areas than in agricultural areas; median concentrations of nitrite, nitrate, and nitrite plus nitrate nitrogen were higher in agricultural areas than in urban and forested/wetland areas; and ammonia, total

    Objectives: Hepatitis C virus (HCV) is the most common chronic blood borne viral infection in the United States. We assessed the HCV prevalence, risk factors, and sensitivity of the Centers for Disease Control and Prevention's (CDC) routine screening criteria among clients of a large urban sexually transmitted disease (STD) clinic. Methods: Participants were recruited from a public STD clinic in Miami, Florida, and were interviewed regarding known and potential risk factors. The survey assessed CDC screening criteria, as well as other risk factors (for example, intranasal drug use, history of incarceration, exchanging sex for money, number of lifetime sex partners, and history of an STD). Testing was done by enzyme immunoassay (EIA) and confirmed by recombinant immunoblot assay (RIBA). Results: The prevalence of anti-HCV positivity was 4.7%. Four variables were significantly associated with being anti-HCV positive, independent of confounding factors. These included injection drug use (odds ratio (OR) = 31.6; 95% confidence intervals (CI) 11.0 to 90.5); history of incarceration (OR = 3.0; 95% CI 1.1 to 8.1); sexual contact with an HCV positive person (OR 12.7; 95% CI 2.5 to 64.7); and older age (OR 1.4; 95% CI 1.2, 1.6). The sensitivity of CDC's routine screening criteria was 69% and specificity was 91%. Conclusions: The prevalence of anti-HCV in this clinic was similar to that determined in studies of comparable populations. Having sexual contact with an HCV positive person and history of incarceration were independently associated with being anti-HCV positive. CDC's screening criteria identified approximately two thirds of the anti-HCV positive participants. PMID:12576631

    Synechococcus sp. strain Miami BG 043511 exhibits very high H[sub 2] photoproduction from water, but the H[sub 2] photo-production capability is lost rapidly with the age of the batch culture. The decrease of the capability coincides with the decrease of cellular glucose content. However, H[sub 2] photoproduction capability can be restored by the addition of organic substrates. Among 40 organic compounds tested, carbohydrates such as glucose, fructose, maltose, and sucrose were effective electron donors. Among organic acids tested, only pyruvate was an effective electron donor. Among alcohols tested, glycerol was a good electron donor, whereas ethanol was a poor but positive electron donor. These results demonstrate that this unicellular cyanobacterium exhibits a wide substrate specificity for H[sub 2] photoproduction but has a different substrate specificity compared to photosynthetic bacteria. The maximum rates of H[sub 2] photoproduction from a 6-day-old batch culture with 25 mmol of pyruvate, glucose, maltose, sucrose, fructose, and glycerol were 1.11, 0.62, 0.05, 0.47, 0.30, and 0.39 [mu]moles per mg cell dry weight per hour respectively. Therefore, this cyanobacterial strain may have a potential significance in removing organic materials from the wastewater and simultaneously transforming them to H[sub 2] gas, a pollution-free energy. The activity of nitrogenase, which catalyzes hydrogen production, completely disappeared when intracellular glucose was used up, but it could be restored by the addition of organic substrates such as glucose and pyruvate.

    In 1999 and 2000, the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program conducted a national pilot study of pesticides and degradates in drinking-water supplies, in cooperation with the U.S. Environmental Protection Agency (USEPA). William H. Harsha Lake, which provides drinking water for several thousand people in southwestern Ohio, was selected as one of the drinking-water supplies for this study. East Fork Little Miami River is the main source of water to Harsha Lake and drains a predominantly agricultural basin. Samples were collected from the East Fork Little Miami River upstream from Harsha Lake, at the drinking-water intake at Harsha Lake, at the outfall just below Harsha Lake, and from treated water at the Bob McEwen Treatment Plant. These samples were analyzed using standardized methods developed for the NAWQA Program. In all, 42 pesticide compounds (24 herbicides, 4 insecticides, 1 fungicide, and 13 degradates) were detected at least once in samples collected during this study. No compound in the treated water samples exceeded any drinking-water standard, although atrazine concentrations in untreated water exceeded the USEPA Maximum Contaminant Level (MCL) for drinking water (3 ?g/L) on four occasions. At least eight compounds were detected with greater than 60 percent frequency at each sampling location. Herbicides, such as atrazine, alachlor, acetochlor, cyanazine, metolachlor, and simazine, were detected most frequently. Rainfall affected the pesticide concentrations in surface waters of the East Fork Little Miami River Basin. Drought conditions from May through November 1999 led to lower streamflow and pesticide concentrations throughout southwestern Ohio. More normal climate conditions during 2000 resulted in higher streamflows and seasonally higher concentrations in the East Fork Little Miami River and Harsha Lake for some pesticides Comparison of pesticide concentrations in untreated lake water and treated drinking water

    The technique of cellular immobilization was applied to the process of hydrogen photoproduction of nonheterocystous, filamentous marine blue-green alga, Oscillatoria sp. Miami BG 7. Immobilization with agar significantly improved the rate and longevity of hydrogen production, compared to free cell suspensions. Rates of H2 production in excess of 13 microliters H2 mg dry/wt h were observed and hydrogen production was sustained for three weeks. Immobilization also provided some stabilization to environmental variability and was adaptable to outdoor light conditions. In general, immobilization provides significant advantages for the production and maintenance of hydrogen photoproduction for this strain.

    Horton, Sarah; Leventhal, Laura

    Universal usability of World Wide Web (Web) environments—that is, having 90% of households as successful users—requires universal access, usability, and universal design. Factors such as Web technology and user-centered design contribute to universal access and usability, but key to universal usability is a universal design methodology. Universal design principles for the Web follow from universal design principles for the built environment, and emphasize perceptibility, self-explanation, and tailorability for the user. Universally usable Web environments offer the benefit of expanded participation, as well as the unanticipated benefits that generally follow from innovative design initiatives. However, to achieve Web universal usability, Web designers need tools that facilitate the design of intuitive interfaces without sacrificing universal access.
