Air pollution represents the biggest environmental risk for health. It is so widespread and it represents one of the main problems of the worldwide, especially because it is emitted by so many different types of sources. The pollutants can originate directly by exhausted or they can be formed because of the reaction with the atmosphere. The first one includes particulate matter and gaseous pollutants such as sulfur oxides, nitrogen oxides, and carbon oxides. The second one includes the ozone formed from nitrogen oxides and hydrocarbons, and particulate sulfate and nitrate aerosols created in the atmosphere from sulfur and nitrogen oxide gases. During the entire life course, people are exposed to the pollutants and suffer from different consequences depending on the age. The first nine month of life are generally recognized as more critical than latter time periods. The mortality associated to air pollutant exposure is main related to the concentrations of NOx , ozone, carbon monoxide, sulfur dioxides and particular matter. More than 92% of the world's population lives in places where air quality levels exceed the standards. In 2012, one out of every nine deaths was the result of air pollution-related conditions. In 2016 about 3 million deaths a year were linked to exposure to outdoor air pollution. In the last few years many epidemiological studies have shown associations between air pollutant concentrations and human health. Apart from people, even monuments and artworks can be damaged by pollution, especially in city centres. Furthermore, urbanization modified microclimate conditions of the cities, and, together with traffic and domestic heating, led to a discomfort of living conditions. For these reasons, there is the necessity to improve the research on the impact of pollutant and microclimate conditions inside urban areas. In this work different kinds of pollutants in Rome from 2006 to 2015 were analysed, and different techniques of post elaboration were used

The design and microwave simulation of two-to-one microstrip power combiners is described. The power combiners were designed for use in a four element phase array receive antenna subarray at 20 GHz. Four test circuits are described which were designed to enable testing of the power combiner and the four element phased array antenna. Test Circuit 1 enables measurement of the two-to-one power combiner. Test Circuit 2 enables measurement of the four-to-one power combiner. Test Circuit 3 enables measurement of a four element antenna array without phase shifting MMIC's in order to characterize the power combiner with the antenna patch-to-microstrip coaxial feedthroughs. Test circuit 4 is the four element phased array antenna including the RADC MMIC phase shifters and appropriate interconnects to provide bias voltages and control phase bits.

2016-07-01

Full Text Available Nature-based solutions have been identified by the European Union as being critical for the enhancement of environmental qualities in cities, where urban and peri-urban forests play a key role in air quality amelioration through pollutant removal. A remote sensing and geographic information system (GIS approach was applied to the Metropolitan City (MC of Rome to assess the seasonal particulate matter (PM10 removal capacity of evergreen (broadleaves and conifers and deciduous species. Moreover, a monetary evaluation of PM10 removal was performed on the basis of pollution externalities calculated for Europe. Deciduous broadleaves represent the most abundant tree functional group and also yielded the highest total annual PM10 deposition values (1769 Mg. By contrast, PM10 removal efficiency (Mg·ha−1 was 15%–22% higher in evergreen than in deciduous species. To assess the different removal capacity of the three functional groups in an area with homogeneous environmental conditions, a study case was performed in a peri-urban forest protected natural reserve (Castelporziano Presidential Estate. This study case highlighted the importance of deciduous species in summer and of evergreen communities as regards the annual PM10 removal balance. The monetary evaluation indicated that the overall PM10 removal value of the MC of Rome amounted to 161.78 million Euros. Our study lends further support to the crucial role played by nature-based solutions for human well-being in urban areas.

ROME (Request Object Management Environment)

Kong, M.; Good, J. C.; Berriman, G. B.

Most current astronomical archive services are based on an HTML/ CGI architecture where users submit HTML forms via a browser and CGI programs operating under a web server process the requests. Most services return an HTML result page with URL links to the result files or, for longer jobs, return a message indicating that email will be sent when the job is done. This paradigm has a few serious shortcomings. First, it is all too common for something to go wrong and for the user to never hear about the job again. Second, for long and complicated jobs there is often important intermediate information that would allow the user to adjust the processing. Finally, unless some sort of custom queueing mechanism is used, background jobs are started immediately upon receiving the CGI request. When there are many such requests the server machine can easily be overloaded and either slow to a crawl or crash. Request Object Management Environment (ROME) is a collection of middleware components being developed under the National Virtual Observatory Project to provide mechanism for managing long jobs such as computationally intensive statistical analysis requests or the generation of large scale mosaic images. Written as EJB objects within the open-source JBoss applications server, ROME receives processing requests via a servelet interface, stores them in a DBMS using JDBC, distributes the processing (via queuing mechanisms) across multiple machines and environments (including Grid resources), manages realtime messages from the processing modules, and ensures proper user notification. The request processing modules are identical in structure to standard CGI-programs -- though they can optionally implement status messaging -- and can be written in any language. ROME will persist these jobs across failures of processing modules, network outages, and even downtime of ROME and the DBMS, restarting them as necessary.

Full Text Available In February 2017 the “Carbonaceous Aerosol in Rome and Environs (CARE” experiment was carried out in downtown Rome to address the following specific questions: what is the color, size, composition, and toxicity of the carbonaceous aerosol in the Mediterranean urban background area of Rome? The motivation of this experiment is the lack of understanding of what aerosol types are responsible for the severe risks to human health posed by particulate matter (PM pollution, and how carbonaceous aerosols influence radiative balance. Physicochemical properties of the carbonaceous aerosol were characterised, and relevant toxicological variables assessed. The aerosol characterisation includes: (i measurements with high time resolution (min to 1–2 h at a fixed location of black carbon (eBC, elemental carbon (EC, organic carbon (OC, particle number size distribution (0.008–10 μ m, major non refractory PM1 components, elemental composition, wavelength-dependent optical properties, and atmospheric turbulence; (ii 24-h measurements of PM10 and PM2.5 mass concentration, water soluble OC and brown carbon (BrC, and levoglucosan; (iii mobile measurements of eBC and size distribution around the study area, with computational fluid dynamics modeling; (iv characterisation of road dust emissions and their EC and OC content. The toxicological assessment includes: (i preliminary evaluation of the potential impact of ultrafine particles on lung epithelia cells (cultured at the air liquid interface and directly exposed to particles; (ii assessment of the oxidative stress induced by carbonaceous aerosols; (iii assessment of particle size dependent number doses deposited in different regions of the human body; (iv PAHs biomonitoring (from the participants into the mobile measurements. The first experimental results of the CARE experiment are presented in this paper. The objective here is to provide baseline levels of carbonaceous aerosols for Rome, and to address

Population-based studies of the prevalence of all functional gastrointestinal disorders (FGID) using the Rome II criteria are lacking. It is also not certain whether subjects who meet the Rome II criteria for an FGID are different in terms of demographic and psychological characteristics from those subjects meeting exclusively the more restrictive Rome I criteria. To determine whether using the more restrictive Rome I criteria would result in a more biologically determined group of FGID than when the Rome II is applied. Subjects included individuals aged 18 years and older (n = 1,225) from the Penrith population who were initially surveyed with the Penrith District Health Survey in 1997. Subjects were sent a self-report questionnaire that contained items on gastrointestinal symptoms applying the Rome II criteria. Subjects were also assessed on psychological and personality factors and on physical and mental functioning. A total of 36.1% (n = 275) of respondents was diagnosed with an FGID according to Rome II criteria. The five most prevalent FGID were functional heartburn (10.4%), irritable bowel syndrome (8.9%), functional incontinence (7.6%), proctalgia fugax (6.5%) and functional chest pain (5.1%). Subjects meeting Rome II only criteria for FGID scored significantly higher on measures of psychological caseness and emotionality than Rome I only subjects, and these were independently associated with meeting Rome I only versus Rome II only criteria for FGID. The Rome II criteria FGID are common and do not appear to identify a vastly different group of FGID sufferers compared with the earlier Rome I criteria.

Eternal Rome: Guardian of the Heavenly Gates

Science.gov (United States)

Latura, G.

2016-01-01

The power of the Roman Empire did not come solely by way of brutal force. A spiritual vision inherited from the Greeks inspired the Romans—an ascent through the classical Planets to the intersections with the Milky Way, where stood the gates of heaven. This vision stretches back, through Macrobius and Cicero, to Plato's Republic and Timaeus. The Eternal City, capital of the Empire for four centuries, claimed control over the celestial portals, a tradition that is traced on Roman coins and medals over thousands of years. Julius Caesar borrowed enormous sums to campaign for the office of Pontifex Maximus—high priest of Rome—spending a fortune on “bread and circuses” to secure the support of the masses. Consolidating power at every turn, Caesar as dictator-for-life became absolute master of Rome, the city that, according to its coins, ruled the cosmos. Though his mortal frame fell to the knives of the senators, Caesar's soul was seen ascending to heaven as a comet. Thus was born the myth of Divvs Ivlivs—the divine avatar of the Roman Empire, whose name would become synonymous with the title of emperor over millennia (German Kaiser, Hungarian Csaszar, Russian Tsar, to name a few). Caesar's heir, Octavian, piously waited for Lepidus to die of old age before grabbing the office of Pontifex Maximus for himself, a title that would define the celestial authority of the ruler of Rome until Gratian renounced it four centuries later. Ambrose, bishop of Milan, convinced Gratian that such a pagan title was not fit for a Christian. Once the Roman emperor discarded the title Pontifex Maximus, the bishop of Rome picked it up and placed it above his own head, as can be seen on coins and medals of the Vatican to this day. In Jubilee years, the Pope knocks down the brick wall that has kept closed the Holy Door for a generation, a ceremony that reaffirms Rome's control of the celestial gates.

Human Trafficking and the Rome Statute of the International Criminal Court

Directory of Open Access Journals (Sweden)

CLARE FRANCES MORAN

2014-12-01

Full Text Available The case for extending the reach of the Rome Statute to the crime of human trafficking has not yet been made in detail. The brutality which occurs when human beings are trafficked by criminal gangs is of an equally egregious nature as the other crimes covered by the Rome Statute and yet it does not fall within the remit of the International Criminal Court. Such trafficking may also fall outwith the definition of slavery as a crime against humanity, particularly given the State policy threshold set by the Statute. This paper seeks to explore the viability of the inclusion of human trafficking as a discrete international crime within the Rome Statute as a response to this loophole.

This paper deals with the analysis of black crust coming from the statue of Oceanus belonging to the Fontana di Trevi (Rome). This monument is undoubtedly one of the main touristic attractions of Rome. During the restoration held between 2014 and 2015, some diagnostic analyses had been carried out. It has been highlighted that the sheltered surfaces suffer the formation of black crust, especially on the marble statues. The possibility to sample those degradation products, together with the unaltered substrate, represented an excellent opportunity to characterize the marble itself, to assess the impact of the urban air pollution on the stone material, and to detect the pollutant on a precise timescale. In fact, it is known that the previous restoration of the fountain had been carried out between 1989 and 1991 then, information about the air pollution over the last 25years can be highlighted, because it has been proved that black crusts act as passive samplers of pollution. In order to fully characterize those samples, several techniques were used, including optical and scanning electron microscopy, X-ray diffraction, laser ablation inductively coupled plasma mass spectrometry, infrared spectroscopy and ion chromatography. Furthermore, a new methodology based on CHN (Carbon, Hydrogen, Nitrogen) analysis has been developed for the quantification of the two main constituents of the carbonaceous fraction present in the black crusts, i.e. OC (organic carbon) and EC (elemental carbon). This integrated approach proposed in the present study allowed us to gain information about the mineralogical phases and the elements within the crusts and at the crust-substrate interface, giving the possibility to identify the pollution sources causing the stone decay within the monument.

2010-05-01

Full Text Available In this work, the trend of the Urban Heat Island (UHI of Rome is analyzed by both ground-based weather stations and a satellite-based infrared sensor. First, we have developed a suitable algorithm employing satellite brightness temperatures for the estimation of the air temperature belonging to the layer of air closest to the surface. UHI spatial characteristics have been assessed using air temperatures measured by both weather stations and brightness temperature maps from the Advanced Along Track Scanning Radiometer (AATSR on board ENVISAT polar-orbiting satellite. In total, 634 daytime and nighttime scenes taken between 2003 and 2006 have been processed. Analysis of the Canopy Layer Heat Island (CLHI during summer months reveals a mean growth in magnitude of 3–4 K during nighttime and a negative or almost zero CLHI intensity during daytime, confirmed by the weather stations.

1994-09-01

A program to jointly study vertical-cavity surface emitting lasers (VCSEL) for high speed vertical optical interconnects (VOI) has been conducted under an ES&E between Rome Laboratory and Cornell University. Lasers were designed, grown, and fabricated at Cornell University. A VCSEL measurement laboratory has been designed, built, and utilized at Rome Laboratory. High quality VCSEL material was grown and characterized by fabricating conventional lateral cavity lasers that emitted at the design wavelength of 1.04 microns. The VCSEL's emit at 1.06 microns. Threshold currents of 16 mA at 4.8 volts were obtained for 30 microns diameter devices. Output powers of 5 mW were measured. This is 500 times higher power than from the light emitting diodes employed previously for vertical optical interconnects. A new form of compositional grading using a cosinusoidal function has been developed and is very successful for reducing diode series resistance for high speed interconnection applications. A flip-chip diamond package compatible with high speed operation of 16 VCSEL elements has been designed and characterized. A flip-chip device binding effort at Rome Laboratory was also designed and initiated. This report presents details of the one-year effort, including process recipes and results.

Rome Criteria and a Diagnostic Approach to Irritable Bowel Syndrome

Directory of Open Access Journals (Sweden)

Brian E. Lacy

2017-10-01

Full Text Available Functional gastrointestinal disorders (FGIDs account for at least 40% of all referrals to gastroenterologists. Of the 33 recognized adult FGIDs, irritable bowel syndrome (IBS is the most prevalent, with a worldwide prevalence estimated at 12%. IBS is an important health care concern as it greatly affects patients’ quality of life and imposes a significant economic burden to the health care system. Cardinal symptoms of IBS include abdominal pain and altered bowel habits. The absence of abdominal pain makes the diagnosis of IBS untenable. The diagnosis of IBS can be made by performing a careful review of the patient’s symptoms, taking a thoughtful history (e.g., diet, medication, medical, surgical, and psychological history, evaluating the patient for the presence of warning signs (e.g., “red flags” of anemia, hematochezia, unintentional weight loss, or a family history of colorectal cancer or inflammatory bowel disease, performing a guided physical examination, and using the Rome IV criteria. The Rome criteria were developed by a panel of international experts in the field of functional gastrointestinal disorders. Although initially developed to guide researchers, these criteria have undergone several revisions with the intent of making them clinically useful and relevant. This monograph provides a brief overview on the development of the Rome criteria, discusses the utility of the Rome IV criteria, and reviews how the criteria can be applied clinically to diagnose IBS. In addition, a diagnostic strategy for the cost-effective diagnosis of IBS will be reviewed.

The updated Rome III Classification of paediatric functional gastrointestinal disorders (FGIDs) associated with abdominal pain comprises: functional dyspepsia (FD), irritable bowel syndrome (IBS), abdominal migraine, functional abdominal pain (FAP), functional abdominal pain syndrome (FAPS). To assess the value of the Rome criteria in identifying FGIDs in children with chronic abdominal pain. The study group consisted of 439 consecutive paediatric patients (192 boys and 247 girls) aged 4-18 years (mean age was 11.95 +/- 3.89 years) referred to the Paediatric Gastroenterology Department at Medical University of Lodz from January 2008 to June 2009 for evaluation of abdominal pain of at least 2 months' duration. After exclusion of organic disease children suspected of functional chronic abdominal pain were categorized with the use of Rome III criteria of FGIDs associated with abdominal pain (H2a-H2d1) and the Questionnaire on Paediatric Gastrointestinal Symptoms (with the permission of doctor L. S. Walker). The patients with known nonabdominal organic disease, chronic illness or handicap were excluded. In 161 patients (36.58%) organic etiology was confirmed. Of the 278 children (63.42%) with functional chronic abdominal pain, 228 (82.02%) met the Rome III criteria for FGIDs associated with abdominal pain (FD, 15.5%; IBS, 21.6%; abdominal migraine, 5%; FAP 24.5%; FAPS, 15.9%). Fifty cases (17.98%) did not fulfill the criteria for subtypes of abdominal pain-related FGIDs--mainly due to different as defined by Rome III criteria (at least once per week) frequency of symptom presentation. (1) In the authors'investigations FGIDs was the most frequent cause of chronic abdominal pain in children. (2) The significant number of children with nonclassified FGIDs implies the need to modify the diagnostic criteria of Rome III classification concerning the prevalence of symptoms.

Rome criteria were formulated to define functional gastrointestinal disorders (Rome III criteria, 2006) excluding organic diagnoses when alarm symptoms were absent. The aims of the study were to validate the Rome III criteria as to their capacity to differentiate between organic and functional abdominal pain and to assess the role of alarm symptoms in this differentiation. During 2 years all of the patients (ages 4-16 years) presenting with recurrent abdominal pain (Apley criteria) and referred to secondary care were included. Clinical diagnoses were based on protocolized evaluation and intervention with 6-month follow-up. Alarm symptoms were registered. Rome III criteria for functional pain syndromes were assigned independently. Descriptive statistical analyses were performed. In 200 patients (87 boys, mean age 8.8 years), organic (17%), functional (40%), combined organic and functional (9%), spontaneous recovery (27%), and other (8%) clinical diagnoses were established. Alarm symptoms were found in 57.5% (organic causes 56%, functional causes 61%). The evaluation for Rome symptom clusters revealed symptoms of irritable bowel syndrome in 27%, functional dyspepsia in 15%, functional abdominal pain in 28%, functional abdominal pain syndrome in 14.5%, and no pain syndrome in 15.5%. Rome diagnoses, based on symptoms and absence of alarm symptoms, predicted functional clinical diagnosis with sensitivity 0.35 (95% confidence interval 0.27-0.43), specificity 0.60 (0.46-0.73), positive predictive value 0.71 (0.61-0.82), and negative predictive value of 0.24 (0.17-0.32). The Rome III criteria for abdominal pain are not specific enough to rule out organic causes. Alarm symptoms do not differentiate between organic and functional abdominal pain.

During all seasons the rainfall shows a significant peak in the south and the southeast exposures, where the highest cover of lithobionts is found. The results show the role of incident rainfall in the climatic conditions of Rome as the main driving factor for the growth of lithobionts on walls where rainfall is their principal source of water. 31 refs., 4 figs., 2 tabs.

Pros and Cons While Looking Through an Asian Window on the Rome IV Criteria for Irritable Bowel Syndrome: Pros.

Science.gov (United States)

Ghoshal, Uday C

2017-07-30

A decade after Rome III, in 2016, Rome IV criteria were published. There are major differences between Rome IV and the earlier iteration, some of which are in line with Asian viewpoints. The clinical applicability of the Rome IV criteria of irritable bowel syndrome (IBS) in Asian perspective is reviewed here. Instead of considering functional gastrointestinal disorders (FGIDs) to be largely psychogenic, Rome IV suggested the importance of the gut over brain ("disorders of gut-brain interaction" not "brain-gut interaction"). The word "functional" is underplayed. Multi-dimensional clinical profile attempts to recognize micro-organic nature, like slow colon transit and fecal evacuation disorders in constipation and dietary intolerance including that of lactose and fructose, bile acid malabsorption, non-celiac wheat sensitivity, small intestinal bacterial overgrowth, and gastrointestinal infection in diarrhea. Overlap between different FGIDs has been recognized as Rome IV suggests these to be a spectrum rather than discrete disorders. Bloating, common in Asia, received attention, though less. Sub-typing of IBS may be more clinician-friendly now as the patient-reported stool form may be used than a diary. However, a few issues, peculiar to Asia, need consideration; Rome IV, like Rome III, suggests that Bristol type I-II stool to denote constipation though Asian experts include type III as well. Work-up for physiological factors should be given greater importance. Language issue is important. Bloating, common in IBS, should be listed in the criteria. Threshold values for symptoms in Rome IV criteria are based on Western data. Post-infectious malabsorption (tropical sprue) should be excluded to diagnose post-infectious IBS, particularly in Asia.

A program of compositional analysis using neutron activation has been performed on samples of Roman fine ware from the Palatine East excavations in Rome at the University of Illinois' TRIGA reactor. These experiments are ultimately intended to assist the authors in advancing the understanding of the organization of pottery production and distribution in central Italy during the late Roman imperial period (4th-5th c. AD). The objectives of this paper are to present an archaeological background of two regionally-produced fine wares, to discuss the methods of sampling, irradiation and data analyses, and to demonstrate the preliminary results of our investigation, which included the analyses of Plio-Pleistocene clays from the Janiculum Hill in Rome.

A canopy layer model and its application to Rome

International Nuclear Information System (INIS)

Bonacquisti, V.; Casale, G.R.; Palmieri, S.; Siani, A.M.

2006-01-01

An urban canopy layer model based on four energy balance equations at ground level and at building level was developed to simulate and describe the urban climate and the heat storage in an urban setting. Thermal and radiative characteristics of urban and rural surfaces as well as atmospheric parameters related to the general synoptic conditions were used as data input. In addition, buildings were modelled as parallelepipeds and the hysteresis of materials was taken into account. The model provides as output skin temperature of buildings, air temperature and humidity within the canopy layer and hence the mean surface temperature and the air temperature at 2 m above surface. The latter parameter was used for the comparison with in situ temperature observations. The model was applied to Rome in radiative summer and winter episodes. The results, which agree with observations, show that the Urban Heat Island (UHI) is a nocturnal phenomenon, present both in winter (the greatest difference between urban and rural temperatures is about 2 deg. C) and summer (the temperature difference is about 5 deg. C), mainly resulting from the urban geometry and the thermal properties of materials. The anthropogenic heat does not play an important role in the UHI development. A monthly nocturnal behaviour of temperature differences between urban and surrounding rural areas shows that the maximum mean value of 4.2 deg. C occurs in August. Moreover, the parks in the city centre, where temperatures are lower, define two distinct heat islands, east and west

Seismic response in archaeological areas: the case-histories of Rome

Donati, Stefano; Funiciello, Renato; Rovelli, Antonio

1999-03-01

Rome is affected by earthquakes associated to three different seismogenic districts: the Central Apennines area, the Colli Albani volcanic area and the Roman area. The major effects were exclusively due to Apennine seismicity and reached in some cases felt intensities up to VII-VIII degree (MCS scale). The predominant role in the damage distribution seems to be played by the local geological conditions. The historical centre of the city is characterized by the presence of two geomorphologic domains: the alluvial plain of Tiber river and the topographic relieves of Roman Hills, where tradition indicates the first site of the city foundation. In particular, the right river side is characterized by the outcropping of the regional bedrock along the Monte Mario-Gianicolo ridge, while the eastern relieves are the remnants of the Sabatini and Albani volcanic plateau, deeply eroded by the Tiber river and its tributaries during the last glacial low-stand (Würm). These domains are characterized by a large difference in seismic response, due to the high impedance contrast between Holocene coarse deposits filling the Tiber Valley and sedimentary and volcanic Plio-Pleistocene units. Seismic damage observed in 150 monuments of downtown Rome was indicating a significant concentration on alluvial recent deposits. This result was confirmed by the geographical distribution of conservation and retrofitting activities subsequent to main earthquakes, mostly related to local geological conditions. The cases of Marcus Aurelius' Column and Colosseum confirmed the influence of the Holocene alluvial network in local seismic response. During 2500 years of history, the monuments of Rome have `memorized' the seismic effects of historical earthquakes. In some cases, the integration of historical and geological research and macroseismic observations may provide original and useful indications to seismologists to define the seismic response of the city. Local site effects represent a serious

Full Text Available Investigations on atmospheric aerosols and their sources were carried out in October/November 2013 and May/June 2014 consecutively in a suburban area of Rome (Tor Vergata and in central Rome (near St Peter's Basilica. During both years a Saharan dust advection event temporarily increased PM10 concentrations at ground level by about 12–17 µg m−3. Generally, in October/November the ambient aerosol was more strongly influenced by primary emissions, whereas higher relative contributions of secondary particles (sulfate, aged organic aerosol were found in May/June. Absolute concentrations of anthropogenic emission tracers (e.g. NOx, CO2, particulate polycyclic aromatic hydrocarbons, traffic-related organic aerosol were generally higher at the urban location. Positive matrix factorization was applied to the PM1 organic aerosol (OA fraction of aerosol mass spectrometer (HR-ToF-AMS data to identify different sources of primary OA (POA: traffic, cooking, biomass burning and (local cigarette smoking. While biomass burning OA was only found at the suburban site, where it accounted for the major fraction of POA (18–24 % of total OA, traffic and cooking were more dominant sources at the urban site. A particle type associated with cigarette smoke emissions, which is associated with a potential characteristic marker peak (m∕z 84, C5H10N+, a nicotine fragment in the mass spectrum, was only found in central Rome, where it was emitted in close vicinity to the measurement location. Regarding secondary OA, in October/November, only a very aged, regionally advected oxygenated OA was found, which contributed 42–53 % to the total OA. In May/June total oxygenated OA accounted for 56–76 % of the OA. Here a fraction (18–26 % of total OA of a fresher, less oxygenated OA of more local origin was also observed. New particle formation events were identified from measured particle number concentrations and size distributions in May/June 2014 at

THE LEISURE IN ANCIENT ROME: CHRONICLES OF AN EMPIRE RISE

Directory of Open Access Journals (Sweden)

Maximiliano KORSTANJE

2009-12-01

Full Text Available The present research is aimed at describing scientifically how the citizenship practiced the leisure in Ancient Rome ranging from I B.C and I D. C centuries. Almost 123 years of history that deserves being uncovered. Readers who wish having clear how leisure conformed in High Empire should refer to classical biographers such as Cornelius Tacitus and Caius Suetonius. In different manners, both have contributed to understand further about how Romans lived. Like in Greece, mythology encouraged the conflict confronting sons against their fathers. The glory, fame and power were values that a child learned from the cradle. For that, in the lapse of few decades Rome transformed in a military and economic power that subdued all known world for more than four centuries. Under such a circumstance, leisure worked as a vehicle towards hegemony and ideology preventing social fragmentation as well as encouraging a rural migration to urban cities.

[Rome: capital of an empire under the banner of political biology (1936-1942)].

Science.gov (United States)

Vallejo, Gustavo

2012-01-01

This paper analyzes the symbolic conformation of Rome and Romanism as important factors in the affirmation of the power of fascism, especially after the proclamation of the Empire in 1936. Within this framework, it explores the role of science in legitimizing the direct correlation of this symbolic universe with a praxis that exalted racial superiority inherited from Ancient Rome. It investigates the links between the eugenic discourse and the exercise of power behind the "biology policy", including fascist organicism and racism. In fact, Rome was the essence of an empire that was reborn after fifteen centuries and, between its historical legacy and the new scenarios created by fascism for disciplining the population, Romanism had to condense all of the merits of the race, encouraging military conquests and promoting responsibility for maintaining racial purity and avoiding "unwanted miscegenation" with conquered peoples. The idea of Romanism also encouraged a continuation of the persecution of Jews started in Germany. Hence, science ratified a widespread idea of the Romanization as a crusade to impose a force, exaggerated on racial grounds, which integrated confidence in environmental factors with a crude biological determinism.

Giovanni Niccolò Servandoni: his early education among Florence, Rome and London

Directory of Open Access Journals (Sweden)

Francesco Guidoboni

2014-12-01

Full Text Available This research work – part of a phd thesis in co-supervision between the " Sapienza " University of Rome and the University of Paris 1 “Panthéon- Sorbonne” - has the objective of investigating the lesser-known aspects of the life of architect Giovanni Niccolò Servandoni, especially the period of his training in Florence and Rome, and the years when he lived in England before his arrival in Paris in 1724. At the same time he was painter, architect and decorator and his name was famous thanks to a large number of sets made for the Opéra and to the design of the façade of the church of Saint- Sulpice in Paris. During his life, Servandoni had the opportunity to travel throughout Europe, where he worked for the major courts of that time, from Paris to London, from Lisbon to Brussels, Vienna, Dresden and Stuttgart. The archival research allowed to make the major breakthroughs, such as the discovery of  the Servandoni stay in Rome between 1719 and 1720, in the Prince Vaini's palace, a man “entiérement attaché à la France” and related to the environment of the Capranica and d'Alibert theaters. This find let us to make some assumptions about his life and his contacts in the papal city. And yet, the study highlighted the strong relationship that he had with the english cultural environment during  his early stay in Rome, that convinced him to take the trip to London. Thanks to this research, Servandoni's complete work - so vaguely interpreted as an anticipation of the “goût à la grecque” and the revival of classicism of the late eighteenth century - is reinterpreted as the result of his training in Italy and England. It is indebted, in fact, that as well the classicism that characterized the Florentine architecture of that period as his close contact with the English Palladian circle and with the Wren, Vanbrugh and Hawksmoor works, exercised a great influence on him.

Beyond the limits of growth. Report to the Club of Rome. Jenseits der Grenzen des Wachstums. Bericht an den Club of Rome

Energy Technology Data Exchange (ETDEWEB)

Pestel, E.

1988-01-01

The author analyses the importance of the report to the Club of Rome 'The Limits of Growth' published by Denis Meadows in 1972, reassesses the value of the book, and goes on to evolve his theses of 'organic growth'. He recapitulates the history of the origin of the previous book and its extraordinary impact as well as, not least, the misunderstandings its statements gave rise to. His concern is above all to give an up-to-date diagnosis and present new ideas for solving the pressing problems of mankind. Thus he develops his own concept for reasonable growth, providing illustrative problem solutions. While this book was taking shape during 1987, it also assumed the character of a programme for other central themes of the Club of Rome, such as the maintenance of peace and security, the efficiency of societies, technology, energy, and the environment. Because of his personal experience gathered in many parts of the 'Third World', the author believes the western and eastern, modern industrialized nations - whether they like it or not - to exert the function of a model for developing countries, especially the 'threshold countries' among them. They must become aware of the responsibility that this role carries with it. (orig./HSCH).

Gruenert, D C; Novelli, G; Dallapiccola, B; Colosimo, A

2002-06-01

The recent surge of DNA sequence information resulting from the efforts of agencies interested in deciphering the human genetic code has facilitated technological developments that have been critical in the identification of genes associated with numerous disease pathologies. In addition, these efforts have opened the door to the opportunity to develop novel genetic therapies to treat a broad range of inherited disorders. Through a joint effort by the University of Vermont, the University of Rome, Tor Vergata, University of Rome, La Sapienza, and the CSS Mendel Institute, Rome, an international meeting, 'Genome Medicine: Gene Therapy for the Millennium' was organized. This meeting provided a forum for the discussion of scientific and clinical advances stimulated by the explosion of sequence information generated by the Human Genome Project and the implications these advances have for gene therapy. The meeting had six sessions that focused on the functional evaluation of specific genes via biochemical analysis and through animal models, the development of novel therapeutic strategies involving gene targeting, artificial chromsomes, DNA delivery systems and non-embryonic stem cells, and on the ethical and social implications of these advances.

Hospitals of Rome in the Early Nineteenth Century: The Apostolic Visit of 1825.

Science.gov (United States)

Duffin, Jacalyn

2016-01-01

Pope Leo XII marked the 1825 Jubilee by visiting the hospitals of Rome. Italy was recovering from the French invasion that had disrupted social and religious structures. The Visitors investigated conditions, and recommended changes. By 1826, eight large hospitals were ordered to unite, but, three years later, the order was rescinded. Based on the Visit's mostly unexamined records in the Vatican Secret Archives, hospital registers, and minutes of the governing council held in the Archivio di Stato di Roma, this paper reconstructs the network of Rome's hospitals in the early 19 th century. It also compares Roman hospitals to its Parisian counterparts, especially with respect to governance and education. Finally, it examines the merger as an early example of a practice that remains vibrant (if controversial) today.

Nonstationary modeling of a long record of rainfall and temperature over Rome

Villarini, Gabriele; Smith, James A.; Napolitano, Francesco

2010-10-01

A long record (1862-2004) of seasonal rainfall and temperature from the Rome observatory of Collegio Romano are modeled in a nonstationary framework by means of the Generalized Additive Models in Location, Scale and Shape (GAMLSS). Modeling analyses are used to characterize nonstationarities in rainfall and related climate variables. It is shown that the GAMLSS models are able to represent the magnitude and spread in the seasonal time series with parameters which are a smooth function of time. Covariate analyses highlight the role of seasonal and interannual variability of large-scale climate forcing, as reflected in three teleconnection indexes (Atlantic Multidecadal Oscillation, North Atlantic Oscillation, and Mediterranean Index), for modeling seasonal rainfall and temperature over Rome. In particular, the North Atlantic Oscillation is a significant predictor during the winter, while the Mediterranean Index is a significant predictor for almost all seasons.

Full Text Available This paper emphasizes the importance of groundwater resources of Rome with regard to its protection, and the associated issues. There are different tipologies of interference between human presence and groundwater in the city, ranging from the presence of water circulating inside the thick layers of anthropogenic deposits, the frequent contamination of groundwater, the presence of mining activities, the presence of archaeological heritage in underground or in low areas affected by flooding also induced by water table rising. Despite the various issues that are found, the knowledge of groundwater resources of Rome can be an important starting point to enhance its protection s and take advantage of the related countless benefits also aim to increase urban resilience.

Virtualizing ancient Rome: 3D acquisition and modeling of a large plaster-of-Paris model of imperial Rome

2005-01-01

Computer modeling through digital range images has been used for many applications, including 3D modeling of objects belonging to our cultural heritage. The scales involved range from small objects (e.g. pottery), to middle-sized works of art (statues, architectural decorations), up to very large structures (architectural and archaeological monuments). For any of these applications, suitable sensors and methodologies have been explored by different authors. The object to be modeled within this project is the "Plastico di Roma antica," a large plaster-of-Paris model of imperial Rome (16x17 meters) created in the last century. Its overall size therefore demands an acquisition approach typical of large structures, but it also is characterized extremely tiny details typical of small objects (houses are a few centimeters high; their doors, windows, etc. are smaller than 1 centimeter). This paper gives an account of the procedures followed for solving this "contradiction" and describes how a huge 3D model was acquired and generated by using a special metrology Laser Radar. The procedures for reorienting in a single reference system the huge point clouds obtained after each acquisition phase, thanks to the measurement of fixed redundant references, are described. The data set was split in smaller sub-areas 2 x 2 meters each for purposes of mesh editing. This subdivision was necessary owing to the huge number of points in each individual scan (50-60 millions). The final merge of the edited parts made it possible to create a single mesh. All these processes were made with software specifically designed for this project since no commercial package could be found that was suitable for managing such a large number of points. Preliminary models are presented. Finally, the significance of the project is discussed in terms of the overall project known as "Rome Reborn," of which the present acquisition is an important component.

Childbirth in ancient Rome: from traditional folklore to obstetrics.

Science.gov (United States)

Todman, Donald

2007-04-01

In ancient Rome, childbirth was a hazardous event for both mother and child with high rates of infant and maternal mortality. Traditional Roman medicine centred on folklore and religious practices, but with the development of Hippocratic medicine came significant advances in the care of women during pregnancy and confinement. Midwives or obstetrices played an important role and applied rational scientific practices to improve outcomes. This evolution from folklore to obstetrics was a pivotal point in the history of childbirth.

Traveling via Rome through the Stereoscope: Reality, Memory, and Virtual Travel

Directory of Open Access Journals (Sweden)

Douglas M. Klahr

2016-06-01

Full Text Available Underwood and Underwood’s 'Rome through the Stereoscope' of 1902 was a landmark in stereoscopic photography publishing, both as an intense, visually immersive experience and as a cognitively demanding exercise. The set consisted of a guidebook, forty-six stereographs, and five maps whose notations enabled the reader/viewer to precisely replicate the location and orientation of the photographer at each site. Combined with the extensive narrative within the guidebook, the maps and images guided its users through the city via forty-six sites, whether as an example of armchair travel or an actual travel companion. The user’s experience is examined and analyzed within the following parameters: the medium of stereoscopic photography, narrative, geographical imagination, and memory, bringing forth issues of movement, survey and route frames of reference, orientation, visualization, immersion, and primary versus secondary memories. 'Rome through the Stereoscope' was an example of virtual travel, and the process of fusing dual images into one — stereoscopic synthesis — further demarcated the experience as a virtual environment.

Fiumicino: New Port City and Gateway of Rome Fiumicino: nuova città portuale e porta di Roma

Directory of Open Access Journals (Sweden)

Luciano Fonti

2009-11-01

Full Text Available The municipality of Fiumicino, indipendent of Rome since 1992, plays two important roles in regional planning: it can be considered both an autonomous town and a satellite city of Rome. Because of its recent history, actually Fiumicino’s territory still presents the outskirts characteristics (many residential areas, lack of important public and private services, low quality of buildings and public spaces, inadequate infrastructures and not the shape of an independent town, although some chief and characteristics elements like the fish market, which is one of the most important of the Mediterranean sea, and the archaeological area of the ancient port, build at the time of the Emperor Traiano (II p.C.. In fact, at that time, Fiumicino had a specific identity: it represented the gate of Rome from the sea thanks to this port, which was renovated several times because of problems concerning the seabed. Then, after many transformations and attempts of requalification, the port was definitively transformed into a fishing dock. Since 1960, Fiumicino has played this ancient role again, thanks to the construction of the Leonardo Da Vinci Airport; now it is considered the gateway of Rome from the air, while the same role from the sea belongs to Civitavecchia’s port. However it’s important to say that the airport and the town are adjacent but not integrated. In fact, today, because of Capital’s process of growth, which absorbs all near minor towns, and because of the airport, Fiumicino is considered only an appendix of Rome, without a specific identity, but in the last years, some infrastructural aspects have been reconsidered, like its geographical position on the cost and the short distance between the town and some important poles like Rome, Civitavecchia’s port and the industrial areas of Gaeta and Pomezia. So the port authority of Civitavecchia has decided to extend its administration to the areas of Gaeta, which just has a trade port, and

Goethe in the Hall and His Journeys in Printed Rome

Directory of Open Access Journals (Sweden)

Victor Plahte Tschudi

2015-12-01

Full Text Available The article focuses on graphic reproductions in Johann Wolfgang von Goethe’s 'Italian Journey'. This travel account gives a clear sense of how important prints were as part of Goethe’s education and preparation for the encounter with classical Roman monuments. As the text itself was edited and rewritten thirty to forty years after the journey itself, however, prints also became crucial in the attempt to remember that journey. In other words, the author of the 'Journey', in contrast to the youthful traveler, no longer sees engravings of Rome, but Rome through engravings. The discussion takes as a point of departure Goethe’s vast collection of prints, still kept in Weimar. Measured up against the references in the travel journal, prints not only reflected his impression of monuments, but also structured those impressions, as the elderly man looks back and reassembles his memories to make an official account of his life. However, it is too easy to ascribe this reliance on prints to a fading memory — on the contrary. As he grows into old age, Goethe’s idea of graphic reproduction evolves in parallel with his increasingly refined theories of nature. His growing preference for prints depicted as ruins reflects the aging author’s own sense of change and transformation.

The use of MRI apparent diffusion coefficient (ADC) in monitoring the development of brain infarction

2011-01-01

To study the rules that apparent diffusion coefficient (ADC) changes with time and space in cerebral infarction, and to provide the evidence in defining the infarction stages. 117 work-ups in 98 patients with cerebral infarction (12 hyperacute, 43 acute, 29 subacute, 10 steady, and 23 chronic infarctions) were imaged with both conventional MRI and diffusion weighted imaging. The average ADC values, the relative ADC (rADC) values, and the ADC values or rADC values from the center to the periphery of the lesion were calculated. The average ADC values and the rADC values of hyperacute and acute infarction lesion depressed obviously. rADC values in hyperacute and acute stage was minimized, and increased progressively as time passed and appeared as 'pseudonormal' values in approximately 8 to 14 days. Thereafter, rADC values became greater than normal in chronic stage. There was positive correlation between rADC values and time (P < 0.01). The ADC values and the rADC values in hyperacute and acute lesions had gradient signs that these lesions increased from the center to the periphery. The ADC values and the rADC values in subacute lesions had adverse gradient signs that these lesions decreased from the center to the periphery. The ADC values of infarction lesions have evolution rules with time and space. The evolution rules with time and those in space can be helpful to decide the clinical stage, and to provide the evidence in guiding the treatment or judging the prognosis in infarction

Full Text Available In the second part of the text about the Filofei’s doctrine of “Moscow, Third Rome,” the author deals with its reception in later periods of Russian intellectual and political history. Although this doctrine in its original form had no explicit imperial or foreign-political connotation, this paper analyzes the interpretations of the “Third Rome idea” that had significant political consequences. Internally, this idea was used by Prince Kurbskii for the criticism of Ivan the Terrible’s politics (XVI Century, as well as the rejection of the church reforms of Patriarch Nikon in the Old Believers’ literature (XVII Century. However, the revival of interest in the idea of the “Third Rome” characterized the Russian nineteenth century when the discussions on the relationship between Russia and the West emerged. Criticizing the reforms by Peter the Great, the classical Slavophiles found confirmation of the Russian cultural originality and superiority in the past of traditional Muscovy. The author highlights the differences between religious-philosophical and geopolitical interpretations of Russian messianism in the works of Russian Slavophiles and Panslavs. In the final section of this article, Russian messianic ideas are put in a relation with the birth of nationalism in the context of the Russian Empire. In this way, the author’s findings call into question the widespread interpretation of the “Third Rome messianism” as a distinctive and exceptional Russian characteristic.

A large body of evidence supports an inverse association between socioeconomic status and mortality. We analysed data from a large cohort of residents in Rome followed-up between 2001 and 2012 to assess the relationship between individual education and mortality. We distinguished five causes of death and investigated the role of age, gender, and birthplace. From the Municipal Register we enrolled residents of Rome on October 21st 2001 and collected information on educational level attained from the 2001 Census. We selected Italian citizens aged 30-74 years and followed-up their vital status until 2012 (n = 1,283,767), identifying the cause of death from the Regional Mortality Registry. We calculated hazard ratios (HRs) for overall and cause-specific mortality in relation to education. We used age, gender, and birthplace for adjusted or stratified analyses. We used the inverse probability weighting approach to account for right censoring due to emigration. We observed an inverse association between education (none vs. post-secondary+ level) and overall mortality (HRs(95%CIs): 2.1(1.98-2.17), males; 1.5(1.46-1.59), females) varying according to demographic characteristics. Cause-specific analysis also indicated an inverse association with education, in particular for respiratory, digestive or circulatory system related-mortality, and the youngest people seemed to be more vulnerable to low education. Our results confirm the inverse association between education and overall or cause-specific mortality and show differentials particularly marked among young people compared to the elderly. The findings provide further evidence from the Mediterranean area, and may contribute to national and cross-country comparisons in Europe to understand the mechanisms generating socioeconomic differentials especially during the current recession period.

Natural building materials, characterised by middle-low-activity concentrations of primordial radionuclides ( 40 K, 232 Th and 238 U series) are widely used in Italy. Since natural materials reflect the geological variability of their sites of origin, a systematic study was carried out in the province of Rome and the results are reported in this paper. In the present work, in order to evaluate average, minimum and maximum contents of primordial radionuclides, more representative lithologies outcropping on the territory of the province of Rome were identified and around 150 samples were collected. Also, these lithologies were characterised from a radioprotection point of view, by means of the evaluation of the index, I, when they are used as building materials. The results confirm the high-primordial radionuclide content within some materials used in Latium (central Italy). Although the study was carried out in a limited area, the results confirm considerable variation in the primordial radionuclide content depending on the sites of origin. (authors)

2015-01-01

Functional gastrointestinal disorders (FGIDs) entail several distinct conditions that collectively account for a sizeable proportion of patients complaining of abdominal pain. Physicians' awareness is fundamental to avoid unnecessary evaluations and to alleviate stress-related problems. This study aimed to assess the relative frequencies of FGIDs and related categories in a selected Iranian population. We conducted this cross-sectional study in a gastroenterology clinic of a tertiary care pediatric hospital in Iran. Children and adolescents between the age of 4 and 18 years referred to the clinic from October 2011 to February 2013 were enrolled if they were diagnosed with FGID according to the Rome III criteria. A structured questionnaire was used to collect data on demographic characteristics, pain location, duration and frequency, associated symptoms, and pertinent family history. We used descriptive analyses to show mean (±SD) and relative frequencies of categories of FGIDs. We diagnosed 183 (114 female) with FGIDs out of 1307 children and adolescents who were visited in the clinic. There was history of psychiatric disorders in 42 (22.9%) participants, and migraine headaches and gastrointestinal disorders were at least in one of the parents in 21 (11.5%) and 64 (34.9%) participants, respectively. We defined 84 (46%) patients under Irritable Bowel Syndrome (IBS) category, 38 (21%) under Abdominal Migraine, 26 (14%) under Functional Abdominal Pain, 21 (11%) under Functional Dyspepsia, and 7 (4%) under Functional Abdominal Pain Syndrome. Seven children (4%) had no defining feature for FGID categories and therefore labeled as unclassified. FGID was a prevalent diagnosis among children and adolescents with abdominal pain. IBS was the largest category. Only a minority were unclassifiable under the Rome III criteria, indicating improved differentiation characteristics of Rome III criteria compared to the Rome II version.

Although 30-50% of constipated patients exhibit dyssynergia, an optimal method of diagnosis is unclear. Recently, consensus criteria have been proposed but their utility is unknown. To examine the diagnostic yield of colorectal tests, reproducibility of manometry and utility of Rome II criteria. A total of 100 patients with difficult defecation were prospectively evaluated with anorectal manometry, balloon expulsion, colonic transit and defecography. Fifty-three patients had repeat manometry. During attempted defecation, 30 showed normal and 70 one of three abnormal manometric patterns. Forty-six patients fulfilled Rome criteria and showed paradoxical anal contraction (type I) or impaired anal relaxation (type III) with adequate propulsion. However, 24 (34%) showed impaired propulsion (type II). Forty-five (64%) had slow transit, 42 (60%) impaired balloon expulsion and 26 (37%) abnormal defecography. Defecography provided no additional discriminant utility. Evidence of dyssynergia was reproducible in 51 of 53 patients. Symptoms alone could not differentiate dyssynergic subtypes or patients. Dyssynergic patients exhibited three patterns that were reproducible: paradoxical contraction, impaired propulsion and impaired relaxation. Although useful, Rome II criteria may be insufficient to identify or subclassify dyssynergic defecation. Symptoms together with abnormal manometry, abnormal balloon expulsion or colonic marker retention are necessary to optimally identify patients with difficult defecation.

Full Text Available Abstract Background Questionnaires are used in research and clinical practice. For gastrointestinal complaints the Rome II questionnaire is internationally known but not validated. The aim of this study was to validate a printed and a computerized version of Rome II, translated into Swedish. Results from various analyses are reported. Methods Volunteers from a population based colonoscopy study were included (n = 1011, together with patients seeking general practice (n = 45 and patients visiting a gastrointestinal specialists' clinic (n = 67. The questionnaire consists of 38 questions concerning gastrointestinal symptoms and complaints. Diagnoses are made after a special code. Our validation included analyses of the translation, feasibility, predictability, reproducibility and reliability. Kappa values and overall agreement were measured. The factor structures were confirmed using a principal component analysis and Cronbach's alpha was used to test the internal consistency. Results and Discussion Translation and back translation showed good agreement. The questionnaire was easy to understand and use. The reproducibility test showed kappa values of 0.60 for GERS, 0.52 for FD, and 0.47 for IBS. Kappa values and overall agreement for the predictability when the diagnoses by the questionnaire were compared to the diagnoses by the clinician were 0.26 and 90% for GERS, 0.18 and 85% for FD, and 0.49 and 86% for IBS. Corresponding figures for the agreement between the printed and the digital version were 0.50 and 92% for GERS, 0.64 and 95% for FD, and 0.76 and 95% for IBS. Cronbach's alpha coefficient for GERS was 0.75 with a span per item of 0.71 to 0.76. For FD the figures were 0.68 and 0.54 to 0.70 and for IBS 0.61 and 0.56 to 0.66. The Rome II questionnaire has never been thoroughly validated before even if diagnoses made by the Rome criteria have been compared to diagnoses made in clinical practice.

Estimation of strong ground motion and micro-zonation for the city of Rome

International Nuclear Information System (INIS)

Faeh, D.; Iodice, C.; Suhadolc, P.; Panza, G.F.

1994-03-01

A hybrid technique, based on mode summation and finite differences, is used to simulate the ground motion induced in the city of Rome by possible earthquakes occurring in the main seismogenetic areas surrounding the city: the Central Apennines and the Alban Hills. The results of the numerical simulations are used for a first order seismic micro-zonation in the city of Rome, which can be used for the retrofitting of buildings of special social and cultural value. Rome can be divided into six main zones: (1) the edge and (2) the central part of the alluvial basin of the river Tiber; (3) the edges and (4) the central part of the Paleotiber basin; the areas outside the large basins of the Tiber and Paleotiber, where we distinguish between (5) areas without, and (6) areas with a layer of volcanic rocks close to the surface. The strongest amplification effects have to be expected at the edges of the Tiber basin, with maximum spectral amplification of the order of 5 to 6, and strong amplifications occur inside the entire alluvial basin of the Tiber. The presence of a near-surface layer of rigid material is not sufficient to classify a location as a ''hard-rock site'', when the rigid material covers a sedimentary complex. The reason is that the underlying sedimentary complex causes amplifications at the surface due to resonance effects. This phenomenon can be observed in the Paleotiber basin, where spectral amplifications in the frequency range 0.3-1.0 Hz reach values of the order of 3 to 4. (author). 17 refs, 5 figs, 2 tabs

The environmental influence of biomass burning for civil uses was investigated through the determination of several air toxicants in the town of Leonessa and its surroundings, in the mountain region of central Italy. Attention was focussed on PM 10 , polycyclic aromatic hydrocarbons (PAHs) and regulated gaseous pollutants (nitrogen dioxide, ozone and benzene). Two in-field campaigns were carried out during the summer 2012 and the winter 2013. Contemporarily, air quality was monitored in Rome and other localities of Lazio region. In the summer, all pollutants, with the exception of ozone, were more abundant in Rome. On the other hand, in the winter, PAH concentration was higher in Leonessa (15.8 vs. 7.0 ng/m 3 ), while PM 10 was less concentrated (22 vs. 34 μg/m 3 ). Due to lack of other important sources and to limited impact of vehicle traffic, biomass burning was identified as the major PAH source in Leonessa during the winter. This hypothesis was confirmed by PAH molecular signature of PM 10 (i.e. concentration diagnostic ratios and 206 ion mass trace in the chromatograms). A similar phenomenon (i.e. airborne particulate levels similar to those of the capital city but higher PAH loads) was observed in other locations of the province, suggesting that uncontrolled biomass burning contributed to pollution across the Rome metropolitan area.

Full Text Available Objective. Over the last few years, a wide number of unregulated substances have been marketed on the Web and in smart and head shops; they are usually advertised as legal alternatives to commonly known drugs and are defined as “smart drugs,” “legal highs,” and “novel psychoactive substances” (NPS. Aim of our work is to describe use habits and distribution of NPS in a population of young adults in Rome club scene. Methods. A self-administered questionnaire was proposed to subjects over 18 years of age at the entrance of 5 nightclubs in Rome. Socioeconomic characteristics and substance use were investigated. Results. Preliminary results give evidence that 78% of respondents have a lifetime history of NPS use. In addition, 56% of the sample has consumed illicit drugs in the past and 39% has used psychoactive substances in the 12 hours preceding the questionnaire administration. Conclusions. A significant proportion of subjects report use of novel psychoactive substances; traditional illicit drugs consumption, particularly cocaine, appears to be very high as well in the club scene. These data highlight a serious public health challenge, since pharmacological, toxicological, and psychopathological effects linked to interactions among all these substances may be unpredictable and sometimes fatal in vulnerable individuals.

RNA interference (RNAi) is known to play an important part in defence against viruses in a range of species. Second-generation sequencing technologies allow us to assay these systems and the small RNAs that play a key role with unprecedented depth. However, scientists need access to tools that can condense, analyse and display the resulting data. Here, we present viRome, a package for R that takes aligned sequence data and produces a range of essential plots and reports. viRome is released under the BSD license as a package for R available for both Windows and Linux http://virome.sf.net.

Full Text Available After their defeat in the First Punic War, the Carthaginians, led by the Barcids, initiated the extension of their domains in Spain. Their movements did not slip by the Romans, who developed a series of diplomatic maneuvers. The ?rst possible contact with Hamilcar was followed by an agreement with his successor Hasdrubal. Unlike these measures, that would have favored a climate of dialog between both powers, the approximation of Rome to Sagunto, and Hannibal’s assault against the second one, produced unleashed tensions that ?nally culminate with the declaration of a new con?ict. The aim of this paper is to analyze the evolution of the diplomatic relationships between Rome and Carthage during the interwar period, paying special attention to their motivations, premeditation and ef?ciency, as well as to the perceptions that they could provoke in both sides.

Full Text Available La educación física y el deporte retrocedió —en la Roma antigua— respecto a los ideales físico-corporales griegos. Por contra, se fomentó una notable cultura de espectáculos y divertimentos, especialmente durante la época imperial. A fin de dar cobijo a los diversos espectáculos se construyeron en la ciudad de Roma —y por mimetismo en todas las urbes del Imperio— sofisticados edificios. En efecto, además de una importante red de circos —el más emblemático de los cuales fue el circo Máximo—, se levantaron anfiteatros y termas, amén del estadio de Dominiciano. La autora pasa revista a las distintas instalaciones «deportivas» de la Roma antigua, así como a los espectáculos que albergaban: las carreras del circo, los combates de gladiadores, las cacerías de fieras, las naumaquias, sin olvidar las competiciones del estadio y la pasión romana por las termas.Sport and physical education —in Ancient Rome-, looked back to the physical ideals of the Greeks. In contrast, there was also a specific encouragement of spectacles and performance or general entertainment during the Imperial Era. In order to cater for the diverse shows, sophisticated buildings were constructed in Rome, and reproduced in all the built-up areas throughout the Empire. In fact, besides the important circus network, the most emblematic of these being Maximo's Circus, amphitheatres, arenas and spa resorts were constructed, in addition to the Dominitian Stadium. The author studies the different types of «sporting» installations in Ancient Rome, considering the entertainments which took place in them: chariot races, gladiatorial combat, the hunting of wild beasts, naval combats, the stadium sports and, of course, the Roman passion for spas and hot baths.

The 5th ATLAS Physics Workshop in Rome: Report from the Physics Sessions

CERN Multimedia

Cobal, M

The 5th ATLAS physics workshop took place between the 6th and the 11th of June in Rome (after Trest '95, Grenoble '98, Lund '01, and Athens '03). This event turned out to be a great occasion to review the status of the physics and detector performance studies, under the beautiful sun of Rome. It is quite difficult to summarize the 100 talks (for a total of about 35 hours of presentations and discussions): I will just try to give here the general flavour of the workshop structure and conclusions. Four groups represented the Combined Detector Performances: Flavour tagging, E/gamma, Muon Combined and Jet/missing-transverse-energy/Tau. The main focus has been on the results of trigger studies: one introductory and one final talk provided the frame for more detailed presentations embedded in the relevant sessions. Progress was shown also from the Combined Testbeam analyses, where the data from the full ATLAS slice, collected in 2004, are being validated on real data reconstruction algorithms.

The ancient city of Rome, its empire, and the spread of tuberculosis in Europe.

Science.gov (United States)

Eddy, Jared J

2015-06-01

The formation of the Roman Empire constituted an unprecedented joining of Mediterranean and European lands and peoples, centering on the capital of Rome. During the late Roman Republic and early Roman Empire (ca. 200B.C.-ca. 200 A.D.) urbanization and population growth led to conditions favorable to the spread of tuberculosis throughout Italy and especially within Rome itself. Trade and military expansion would have acted as vehicles for the further extension of tuberculosis to the provinces via direct transmission from Italian-born Romans to the native populations. However, an alternative explanation may better explain the increase in the number of archeological cases of tuberculosis with the start of the Roman era. A literature review of Roman-era cases and their locations suggests that the development of an urban, Roman way of life resulted in significant increases in prevalence in regions where tuberculosis had previously been endemic only at a low level.

Full Text Available Abstract Background To study the rules that apparent diffusion coefficient (ADC changes with time and space in cerebral infarction, and to provide the evidence in defining the infarction stages. Methods 117 work-ups in 98 patients with cerebral infarction (12 hyperacute, 43 acute, 29 subacute, 10 steady, and 23 chronic infarctions were imaged with both conventional MRI and diffusion weighted imaging. The average ADC values, the relative ADC (rADC values, and the ADC values or rADC values from the center to the periphery of the lesion were calculated. Results The average ADC values and the rADC values of hyperacute and acute infarction lesion depressed obviously. rADC values in hyperacute and acute stage was minimized, and increased progressively as time passed and appeared as "pseudonormal" values in approximately 8 to 14 days. Thereafter, rADC values became greater than normal in chronic stage. There was positive correlation between rADC values and time (P Conclusion The ADC values of infarction lesions have evolution rules with time and space. The evolution rules with time and those in space can be helpful to decide the clinical stage, and to provide the evidence in guiding the treatment or judging the prognosis in infarction.

Strange history: the fall of Rome explained in Hereditas.

Science.gov (United States)

Bengtsson, Bengt O

2014-12-01

In 1921 Hereditas published an article on the fall of Rome written by the famous classical scholar Martin P:son Nilsson. Why was a paper on this unexpected topic printed in the newly founded journal? To Nilsson, the demise of the Roman Empire was explained by the "bastardization" occurring between "races" from different parts of the realm. Offspring from mixed couples were of a less stable "type" than their parents, due to the breaking up by recombination of the original hereditary dispositions, which led to a general loss of competence to rule and govern. Thus, the "hardness" of human genes, together with their recombination, was - according to Nilsson - the main cause of the fall of Rome. Nilsson's argument is not particularly convincingly presented. Human "races" are taken to have the same genetic structure as inbred crop strains, and Nilsson believes in a metaphysical unity between the individual and the race to which it belongs. However, in my view, Martin P:son Nilsson and his friend Herman Nilsson-Ehle had wider aims with the article than to explain a historical event. The article can be read as indicating strong support from the classical human sciences to the ambitious new science of genetics. Support is also transferred from genetics to the conservative worldview, where the immutability and inflexibility of the Mendelian genes are used to strengthen the wish for greater stability in politics and life. The strange article in Hereditas can, thus, be read as an early instance in the - still ongoing - tug-of-war between the conservative and the liberal ideological poles over how genetic results best are socially interpreted. © 2015 The Authors.

The clinical differentiation of Parkinson's disease (PD) from multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) may be challenging, especially in their early stages. The aim of this study was to evaluate the utility of apparent diffusion coefficient (ADC) measurement to distinguish among these degenerative disorders. Twenty-five MSA, 20 PSP, and 17 PD patients and 18 healthy controls were retrospectively studied. Axial diffusion-weighted and T2-weighted images were obtained using a 3-T MR system. Regions of interest (ROIs) were precisely placed in the midbrain, pons, putamen, globus pallidus, caudate nucleus, thalamus, superior cerebellar peduncle, middle cerebellar peduncle, cerebellar white matter, and cerebellar dentate nucleus, and the regional ADC (rADC) value was calculated in each ROI. In MSA, rADC values in the pons, middle cerebellar peduncle, cerebellar white matter, and cerebellar dentate nucleus were significantly higher than in PSP, PD, and controls. Furthermore, rADC values in the posterior putamen were significantly higher in MSA than in PSP and controls. In PSP, rADC values were significantly higher in the globus pallidus and midbrain than in MSA, PD, and controls. Furthermore, rADC values in the caudate nucleus and superior cerebellar peduncle were significantly higher in PSP than in MSA and controls. In PD, there were no significant differences in the rADC values compared to in MSA, PSP, and controls in all regions. Evaluation of rADC values in characteristic lesions in MSA, PSP, and PD by placing ROIs using 3-T systems can provide useful additional information for differentiating these disorders. (orig.)

The Streets of Rome: The Classical Dylan

Richard Thomas

2007-03-01

Full Text Available One of the preoccupations of Dylan scholarship has had to do with his intertexts, where his songs come from, and what meanings they derive from their places of origin, be they textual or musical, secular or religious, ancient or modern. In this article, Thomas explores Dylan’s contact with the ancient worlds of Greece and Rome, evident in particular in the Dylan of the last decade—that is, on the last three albums and in his “autobiography,” *Chronicles: Volume One*. This article counters the attacks of those who cannot distinguish plagiarism—a charge also leveled against the poet Virgil in antiquity—from creative reuse. Thomas discusses Dylan’s reperformance and lyrical renovation and variation from the perspective of the Homeric rhapsode, who like Dylan himself varies his initial text in performance, so creating constant shifts in meaning and emphasis.

All Roads Lead to Rome: Exploring Human Migration to the Eternal City through Biochemistry of Skeletons from Two Imperial-Era Cemeteries (1st-3rd c AD).

Migration within the Roman Empire occurred at multiple scales and was engaged in both voluntarily and involuntarily. Because of the lengthy tradition of classical studies, bioarchaeological analyses must be fully contextualized within the bounds of history, material culture, and epigraphy. In order to assess migration to Rome within an updated contextual framework, strontium isotope analysis was performed on 105 individuals from two cemeteries associated with Imperial Rome-Casal Bertone and Castellaccio Europarco-and oxygen and carbon isotope analyses were performed on a subset of 55 individuals. Statistical analysis and comparisons with expected local ranges found several outliers who likely immigrated to Rome from elsewhere. Demographics of the immigrants show men and children migrated, and a comparison of carbon isotopes from teeth and bone samples suggests the immigrants may have significantly changed their diet. These data represent the first physical evidence of individual migrants to Imperial Rome. This case study demonstrates the importance of employing bioarchaeology to generate a deeper understanding of a complex ancient urban center.

Full Text Available The first judgment of the International Criminal Court has confirmed that article 25 (3 of the Rome Statute adopts the theory of control of the act to distinguish between principals and accessories. On the contrary, since 2003, the ad hoc tribunals’ case law bases the notion of co-perpetration on the Joint Criminal Enterprise doctrine, using a subjective criterion approach. In this article we will first analyze the problems raised by that case law of the ad hoc tribunals, and then, we will study the article of the Rome Statute which apparently most resembles the Joint Criminal Enterprise doctrine: article 25 (3 (d. The article concludes that none of the three categories of that doctrine is included in the said provision.

In Italy, which is rabies-free, the national Law No. 281 [Legge Nazionale 14 agosto 1991. No. 281: Legge Quadro in materia di animali di affezione e prevenzione del randagismo. Gazz. Uff. Rep. Ital. no 203 del 30 agosto 1991: p. 3] on the management of pets and on the control of feral cats has introduced the no-kill policy for this species. Thus, "trap-neuter-release" (TNR) programs have been carried out for >10 years. In this paper we present data on registered colonies and censused cats in Rome from 1991 to 2000; the results of the neutering campaign from 1991 to 2000; and a survey, on 103 cat colonies, on the effects of demographic control of urban feral-cat colonies in the city of Rome, carried out by the local Veterinary Public Services (VPS) in collaboration with the associations of cat care-takers. In 10 years almost 8000 were neutered and reintroduced in their original colony. The spay/neuter campaigns brought about a general decrease in cat number but the percentage of cat immigration (due to abandonment and spontaneous arrival) is around 21%. This suggests that all these efforts without an effective education of people to control the reproduction of house cats (as a prevention for abandonment) are a waste of money, time and energy.

This study focuses on the impact of a program aimed at reducing heat-related mortality among older adults residing in central Rome by counteracting social isolation. The mortality of citizens over the age of 75 living in three Urban Areas (UAs) located in central Rome is compared with that of the residents of four adjacent UAs during the summer of 2015. The data, broken down by UA, were provided by the Statistical Office of the Municipality of Rome, which gathers them on a routine basis. During the summer of 2015, 167 deaths were recorded in those UAs in which the Long Live the Elderly (LLE) program was active and 169 in those in which it was not, implying cumulative mortality rates of 25‰ (SD ± 1.4; Cl 95%: 23–29) and 29‰ (SD ± 6.7; Cl 95%: 17–43), respectively. Relative to the summer of 2014, the increase of deaths during the summer of 2015 was greater in UAs in which the LLE program had not been implemented (+97.3% vs. +48.8%). In conclusion, the paper shows the impact of a community-based active monitoring program, focused on strengthening individual relationship networks and the social capital of the community, on mortality in those over 75 during heat waves.

Gods and Goddesses were invoked by the Romans for the termination of a good delivery. Diana, Juno, Lucina and Cybele were the preferred ones. Sterility was sometimes treated by the whip of the Lupercali of ministers of Pan. The first doctors in Rome were coming from Greece. Celsus, Pliny the Elder were encyclopedists, Rufus an anatomist, Dioscorides a pharmacologist. Archigenes, Aretaeus and Antyllus surgeons. Soranus from Ephesus, was the first to recommend podalic version. His works was a long time buried in a profound oblivion and discovered by scholars during the nineteenth century. Galen was looked as the most famous medical man after Hippocrates. During the Roman Empire of Occident (Byzantine Empire), Oribasius, Aurelianus Caelius, Moschion and above all Aetius and Paul of Aegina wrote many works which were many times plagiarized. Roman laws concerning public health were severe. Midwives took an important action in the care of pregnant women. Roman poets as Plautus, Terence, Lucilius, Catullus, Virgil, Tibullus, Ovid and Martial were many times concerned in their writings with gynecologic or obstetric subjects. Children were easily forsaken. Three Emperors, Trajan, Marcus-Aurelius and Alexander Severius, a writer, Aulu-Gelles, and a rhetor, Quintilian, took protection of them.

2005-09-01

A description of Calliope γ irradiation plant of ENEA-Casaccia Centre (Rome) is presented in this paper. In particular the main characteristics of the irradiation facility necessary to define time and irradiation procedure are summarised. The plant is equipped with dosimetric services that evaluate absorbed doses in materials during irradiation. Dosimetric techniques used are Fricke, RedPerspex and alanine-ESR dosimetries. In the first case, absorbed dose is determined by chemical changes induced in a solution by irradiation and the second method uses the optical density increase induced in dosimeter by irradiation. The last method is based on the analysis of the free radical concentration induced in α-alanine amino-acid during irradiation. The paper provides also a simulation of the γ radiation field inside the irradiation cell realised by using FLUKA code, which includes a good description of the electromagnetic physics down to about 0.1 KeV [it

The population prevalence, clinical characteristics, and associations for Rome IV functional dyspepsia are not known. Following the publication of the Rome IV criteria for functional gastrointestinal disorders, we aimed to assess the prevalence, characteristics, and associations for symptom-based Rome IV functional dyspepsia in adults across the USA, Canada, and the UK. We sent an internet-based cross-sectional health survey to adults in the general population of three English-speaking countries: the USA, Canada, and the UK. We used quota-based sampling to generate demographically balanced and population-representative samples. Individuals were invited to complete an online questionnaire on general health, without mention that the purpose of this survey was to examine gastrointestinal symptoms. We excluded participants who failed two attention-test questions or were excessively inconsistent on the three gastrointestinal questions that were presented twice in the survey for this particular purpose. The survey enquired about demographics, health-care visits, medications, somatisation, quality of life, and symptom-based criteria for Rome IV functional dyspepsia as well as for irritable bowel syndrome (IBS) and functional heartburn. We made subsequent comparisons between participants with Rome IV functional dyspepsia and controls without dyspepsia. The primary objective was to identify participants who fulfilled symptom-based criteria for Rome IV functional dyspepsia and categorise them into postprandial distress syndrome, epigastric pain syndrome, or overlapping subtypes. 6300 general population adults completed the health survey; 2100 each from the USA, Canada, and the UK. 369 responses were deemed inconsistent, leaving data for 5931 adults. Rome IV functional dyspepsia was significantly more prevalent in the USA (232 [12%] of 1949) than in Canada (167 [8%] of 1988) and the UK (152 [8%] of 1994; p<0·0001). The subtype distribution was 61% postprandial distress

Full Text Available Temple of Augustus and Rome, also referred as Monumentum Ancyranum (Ankara Temple, is located near Haci Bayram Mosque in Ulus, Ankara. The temple which was built on behalf of Phrygian God ‘Men’ in 2nd century BC has been destroyed. The temple whose remains are present, on the other hand, was built for Roman Emperor ‘Augustus’ (Gaius Octavius in 25 BC in the name of a commitment sign by King Pilamenes, the son of King Amintos, of Galatia. The positions of the 4 columns in the doorways and 2 columns in the rear sides are recognizable. Currently, only the sidewalls and ornamented door part are remaining. The original testament of Augustus in Temple of Rome, which is written in Latin and Greek and is telling the achievements of Augustus, is imitated in the mosque that is neighboring the wall of Monumentum Ancyranum. Some parts of the patina are spilled because of the climatic parameters (wind, heat, precipitation, and frost. As a result of the petrographic analysis made on the spilled parts of patina, it is concluded that the temple, which has a great importance in the world history, has to be restorated. As a result of the analyses (scanning electron microscope (SEM analysis, EDS, and X-ray diffraction (XRD analysis, inner and outer sides of Naos are being constructed without mortar. In the parts, which are broken from the main body, calcium carbonate (CaCO3 and magnesium carbonate (MgCO3 are detected. Besides, it is observed that the main body of the temple is mainly consisting of calcium mineral. If this temple will be restored in the future, it is important to watch out for the calcium mineral property of the building.

Functional nausea and vomiting disorders (FNVDs) are classified as chronic nausea and vomiting syndrome (CNVS) or cyclic vomiting syndrome (CVS) - CVS includes cannabinoid hyperemesis syndrome. We investigated the population prevalence of FNVDs, their characteristics, and associated factors. In the year 2015, an Internet cross-sectional health survey was completed by 5931 adults in the general populations of 3 English-speaking countries; 2100 participants were in the United States, Canada, or the United Kingdom. Quota-based sampling was used to generate demographically balanced and population-representative samples. The survey collected data on demographics, healthcare visits, medications, somatic symptom severity, quality of life, and symptom-based diagnostic criteria for Rome IV FNVDs as well as for irritable bowel syndrome and functional dyspepsia. Subsequent comparisons were made between Rome IV FNVD subjects and individuals without FNVDs (controls). Overall, 2.2% of the population (n=131) fulfilled symptom-based diagnostic criteria for Rome IV FNVDs - the United States (3%) had a greater prevalence than Canada (1.9%) or the United Kingdom (1.8%) (P=.02). The prevalence of CNVS was similar among the countries, ranging from 0.8% to 1.2%. However, the prevalence of CVS was higher in the United States (2%) than in Canada (0.7%) or the United Kingdom (1%) (P=.03). The proportion of subjects with CVS taking cannabis did not differ significantly among countries (P=.31), although the 7 cases of cannabinoid hyperemesis syndrome were in the United States. A significantly higher proportion of subjects with CVS reported a compulsive need for hot water bathing to alleviate emetic symptoms than subjects with CNVS (44% vs. 19%, P=.03); this behaviour was independent of cannabis but augmented by its use. Subjects with FNVDs had significantly greater health impairment and health care utilization than controls. On multivariate analysis, independent factors associated with FNVDs

The Club of Rome and its computer.

Chase, S

1973-03-01

When the Club of Rome, an assemblage of 75 scientists and businessmen gathered to study the ''predicament of mankind in the face of technology growing at an exponential rate,'' issued its computer study it launched a battle between proponents of gross national product and those favoring quality of life. The computer simulation studied the interaction of population growth, food supply, inductrial production, resource use, and pollution under varying conditions. It concluded that our industrial system is headed for too many people in relation to food and living space, too much production in relation to natural resources, and for too much pollution. This will affect all countries. The traditional economists say the continued growth of the gross national product is the only way to ensure better living conditions while the ecologists point out that quality of life is being destroyed. The author cites arguments both for and against the quality-of-life view. The problem is that continued industrial growth creates wants as well as satisfying them and leads to waste as well as needful consumption. John Stuart Mill stated 100 years ago that the world could not support continued technological expansion and society must reach an equilibrium. 8 steps must be taken if the planet is to reach such an equilibrium, which is essential to the survival of all: 1) a zero rate of population growth, although there may be variations between countries with some over and some under; 2) a zero rate of industrial output with overall new investment equal to overall rate of industrial depreciation; 3) a policy of recycling and conserving material resources; 4) an adequate budget of food, shelter, clothing, health services, and education for every human being (a budget which does not allow for autos and air conditioning); 5) a sharp decline in consumption of material goods in affluent societies with a corresponding shift to more services and an increase in material goods for low energy societies

Limited data are available on the prevalence of multiple sclerosis (MS) in central Italy. The objective of this study is to estimate MS prevalence in the metropolitan area of Rome. We used the capture-recapture method to calculate prevalence estimates in the study area. The selected prevalence day was December 31, 2015. A total of 1,007 patients, with a definite diagnosis of MS according to the revised McDonald's criteria, were considered for crude, age- and sex-specific prevalence estimation. The overall crude prevalence rate was 146.2 cases per 100,000 (95% CI 119.9-172.5). A higher prevalence rate was recorded in females (194.1, 95% CI 149.6-238.6) than in males (93.0, 95% CI 67.2-118.8) with a female to male ratio of 1.8. Age-specific prevalence peaked in the 25-34 , 35-44 and 45-54 years class; moreover, it was found to increase up to the 45-54 years age group in females and the 35-44 years age group in males, decreasing thereafter. The results confirm that the metropolitan area of Rome is a high-risk area for MS. © 2018 S. Karger AG, Basel.

Corrado Giaquinto’s Critical Fortune in Rome and the Reasons for His Departure for Madrid

Directory of Open Access Journals (Sweden)

Pierguidi, Stefano

2016-09-01

Full Text Available Around 1751, Cochin pointed out that the best painters then in Rome were Masucci, Mancini, Battoni and “le chevalier Corado”. Cochin’s statement would seem to be one of the most meaningful indications of the artist’s fame. Modern criticism, however, tends not to distinguish between the nature of Giaquinto’s and Masucci, Mancini and Batoni’s success: while the latter three artists had definitively established themselves as history painters in oil and could work for international patrons without leaving Rome, Giaquinto never succeeded in asserting himself in that capacity and in this medium. Indeed, in his letter Cochin mistook Corrado for the more famous and well-known knight Sebastiano Conca. Being summoned to Madrid was certainly a great achievement for Giaquinto, but leaving Rome was somehow a forced choice because in the 25 years he had spent there since 1727, the painter had never achieved the success to which he aspired.Alrededor de 1751 Cochin indicaba a los que eran considerados los mejores pintores de Roma en la época: Masucci, Mancini, Battoni y “le chevalier Corado”. El pasaje de Cochin representaría una de las demostraciones más significativas de la notoriedad del artista, pero la crítica moderna propende a no distinguir la diferente esencia del éxito de Giaquinto con respecto a lo de los varios Masucci, Mancini y Batoni, citados en la carta de Cochin: mientras que estos últimos habían triunfado definitivamente como pintores de historia al óleo, y podían trabajar para clientela internacional sin dejar Roma, Giaquinto nunca logró imponerse en aquella función. En la carta, de hecho, Cochin confundía y sobreponía Corrado a lo más célebre Sebastiano Conca. La llamada a Madrid fue un gran éxito por Giaquinto, pero la salida fue una elección obligada porque en veinticinco años que pasó en Roma, el pintor nunca obtuvo aquel reconocimiento a lo que ambicionaba.

Full Text Available The earthquake of June 12, 1995 has been located using local and regional data (41°48.8'N, 12°30.8°6E at a depth of about 11.5 km a few kilometers inside the city limit of Rome, in its southernmost part. This is the first event that occurred in Rome for which instrumental data are available. The local magnitude estimated from digital recordings is ML 3.6 and it was largely felt reaching intensity VI MCS. We constrained the focal mechanism by analyzing the S-wave polarization and it agrees well with the distribution of P-wave polarities. The fault plane solution shows a dominant strike slip mechanism (strike 275°, dip 70°, rake - 140°. Seismic moment, M0 = 2.3 ± 0.6 1021dyne × , was computed from S-wave displacement spectra of horizontal components of ground motion digital waveforms. The corresponding source radius ranges between 200 and 500 m, depending on the assumed stress drop (100 bars or 10 bars, respectively. The earthquake was preceded by a ML 2.6 foreshock. The seismic sequence lasted a few days during which 38 aftershocks were recorded. The seismicity pattern shows the characteristics of a mainshock-aftershock sequence, rather than swarm behavior which seems to characterize the activity of the neighboring seismogenic areas of the Alban Hills. We used a master event algorithm to locate some of the aftershocks. Results show that the relocated aftershocks are clustered in a small volume in proximity of the mainshock hypocenter.

Population-based surveys on the quality of life of people with Down syndrome (DS) are difficult to perform because of ethical and legal policies regarding privacy and confidential information, but they are essential for service planning. Little is known about the sample size and variability of quality of life of people with DS living in the city of Rome, which has a population of 2.7 million inhabitants. The aim of the present study is to explore the needs and challenges in health, social integration and daily life, of people with DS living in Rome. A cross-sectional, census-based survey was conducted in 2006. All family doctors (3016 in total) of the National Health Service were involved by the Statistical Bureau of the Municipality of Rome. As per the census, every resident citizen is registered with a family doctor and every person with disabilities is coded. Associations for Down Syndrome encouraged their members to participate in the research. Questionnaires were completed by families of people with DS, in accordance with privacy laws. An initial survey, conducted via a letter and a telephone contact with family doctors, identified 884 people with DS residing in the city of Rome. Data on the medical and social conditions of 518 people with DS, ranging in age from 0 to 64 years, were collected. Some 88% of these were living with their original family; 82.1% had one or more siblings, and 19.5% had lost one or both parents. A full 100% of children with DS were enrolled in the public school system. This ensures that they are fully occupied and entirely integrated in society. After secondary school there is a lack of opportunities. Thus, only 10% of adults were working with a regular contract. A mere 42.2% of people with DS aged 25-30 were involved in some form of regular activity (although not always on a daily basis). After the age of 30, the percentage of people demonstrating decline in function increased sharply, while disability-related support decreased. In

Morgese, Giorgia; Lombardo, Giovanni Pietro; Albani, Alessandra

2016-11-01

This article examines the areas of research conducted at the Laboratory of Experimental Psychology of the University of Rome from 1907 to 1947, directed first by Sante De Sanctis (1862-1935), and then, from 1931 on, by Mario Ponzo (1882-1960). The method used to distinguish the topics and areas of research that characterized the Roman School during this period is the textual analysis of the titles of the journal in which studies completed at the laboratory were published, namely, Contributi del Laboratorio di Psicologia sperimentale [Psychological Contributions of the Laboratory of Experimental Psychology]. This empirical analysis, which complements and supports the historiographical interpretation, demonstrates the disciplines that emerged under a system managed by the directors over 2 periods of time in the pursuit of scientific psychology in Rome and in Italy. This analysis highlights the process of adjustment from a traditional, general approach to a more theoretical-technical application. This article is a new contribution to the Italian debate on the periodization of the "crisis" in Italian psychology. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Le « Plan de Rome » de Paul Bigot à l’Université de Caen et son double virtuel : de l’objet patrimonial à l’outil scientifique

Full Text Available Le travail de restitution virtuelle de la Rome du IVe siècle ap. J.-C. a commencé à l’Université de Caen Basse-Normandie en 1994. Le prétexte du projet est une maquette en plâtre de 70 m2, réalisée par l’architecte Paul Bigot au début du XXe siècle et connue sous le nom de « Plan de Rome ». Le plan de Rome est un objet patrimonial exceptionnel puisqu’il n’a que deux autres équivalents dans le monde : un double conservé à Bruxelles et la maquette réalisée par I. Gismondi, située au Musée de la civilisation romaine de Rome. La restitution virtuelle est entièrement interactive et comprend à la fois de l’architecture et des systèmes mécaniques. En restituant le passé, les chercheurs peuvent tester leurs hypothèses, sous l’aspect architectural et topographique, ou encore tester le fonctionnement des machines. Le visiteur peut se déplacer dans une ville à l’échelle 1, entrer dans la plupart des édifices publics et dans quelques bâtiments privés. Le travail préliminaire à la restitution est celui de l’analyse des sources anciennes, réalisé dans l’équipe, avec l’aide d’experts extérieurs sur des points particuliers. Les sources sont accessibles en permanence depuis le modèle virtuel.Work on developing a virtual model of the city of Rome in the fourth century A.D. began in Caen in 1994.

2011-01-01

Objective: To estimate the applications of ADC value and rADC value in the diagnosis of nodular lesions of breasts. Methods: Fifty-two cases with 66 nodular lesions of breasts confirmed by histopathology underwent diffusion-weighted magnetic resonance imaging. Three b values (0, 800 and 1000 s/mm 2 ) were applied. The mean ADC values of the breast nodules, the ADC values of ipsilateral breast (rADC 1 ) and ADC values of contralateral breast (rADC 2 ) were respectively measured.

Banner headlines in an Italian newspaper read on May 11, 2011: "Absence boom in offices: the urban legend in Rome become psychosis". This was the effect of a large-magnitude earthquake prediction in Rome for May 11, 2011. This prediction was never officially released, but it grew up in Internet and was amplified by media. It was erroneously ascribed to Raffaele Bendandi, an Italian self-taught natural scientist who studied planetary motions and related them to earthquakes. Indeed, around May 11, 2011, there was a planetary alignment and this increased the earthquake prediction credibility. Given the echo of this earthquake prediction, INGV decided to organize on May 11 (the same day the earthquake was predicted to happen) an Open Day in its headquarter in Rome to inform on the Italian seismicity and the earthquake physics. The Open Day was preceded by a press conference two days before, attended by about 40 journalists from newspapers, local and national TV's, press agencies and web news magazines. Hundreds of articles appeared in the following two days, advertising the 11 May Open Day. On May 11 the INGV headquarter was peacefully invaded by over 3,000 visitors from 9am to 9pm: families, students, civil protection groups and many journalists. The program included conferences on a wide variety of subjects (from social impact of rumors to seismic risk reduction) and distribution of books and brochures, in addition to several activities: meetings with INGV researchers to discuss scientific issues, visits to the seismic monitoring room (open 24h/7 all year), guided tours through interactive exhibitions on earthquakes and Earth's deep structure. During the same day, thirteen new videos have also been posted on our youtube/INGVterremoti channel to explain the earthquake process and hazard, and to provide real time periodic updates on seismicity in Italy. On May 11 no large earthquake happened in Italy. The initiative, built up in few weeks, had a very large feedback

Full Text Available Non-motorized transportation modes, especially cycling and walking, offer numerous benefits, including improvements in the livability of cities, healthy physical activity, efficient urban transportation systems, less traffic congestion, less noise pollution, clean air, less impact on climate change and decreases in the incidence of diseases related to vehicular emissions. Considering the substantial number of short-distance trips, the time consumed in traffic jams, the higher costs for parking vehicles and restrictions in central business districts, many commuters have found that non-motorized modes of transportation serve as viable and economical transport alternatives. Thus, local governments should encourage and stimulate non-motorized modes of transportation. In return, governments must provide safe conditions for these forms of transportation, and motorized vehicle users must respect and coexist with pedestrians and cyclists, which are the most vulnerable users of the transportation system. Although current trends in sustainable transport aim to encourage and stimulate non-motorized modes of transportation that are socially more efficient than motorized transportation, few to no safety policies have been implemented regarding vulnerable road users (VRU, mainly in large urban centers. Due to the spatial nature of the data used in transport-related studies, geospatial technologies provide a powerful analytical method for studying VRU safety frameworks through the use of spatial analysis. In this article, spatial analysis is used to determine the locations of regions that are characterized by a concentration of traffic accidents (black zones involving VRU (injuries and casualties in São Paulo, Brazil (developing country, and Rome, Italy (developed country. The black zones are investigated to obtain spatial patterns that can cause multiple accidents. A method based on kernel density estimation (KDE is used to compare the two cities and show

Contribution for an Urban Geomorphoheritage Assessment Method: Proposal from Three Geomorphosites in Rome (Italy

2017-09-01

Full Text Available Urban geomorphology has important implications in spatial planning of human activities, and it also has a geotouristic potential due to the relationship between cultural and geomorphological heritage. Despite the introduction of the term Anthropocene to describe the deep influence that human activities have had in recent times on Earth evolution, urban geomorphological heritage studies are relatively rare and limited and urban geotourism development is recent. The analysis of the complex urban landscape often need the integration of multidisciplinary data. This study aims to propose the first urban geomorphoheritage assessment method, which originates after long-lasting previous geomorphological and geotouristic studies on Rome city centre, it depict rare examples of the geomorphological mapping of a metropolis and, at the same time, of an inventory of urban geomorphosites. The proposal is applied to geomorphosites in the Esquilino neighbourhood of Rome, whose analysis confirm the need for an ad hoc method for assessing urban geomorphosites, as already highlighted in the most recent literature on the topic. The urban geomorphoheritage assessment method is based on: (i the urban geomorphological analysis by means of multitemporal and multidisciplinary data; (ii the geomorphosite inventory; and (iii the geomorphoheritage assessment and enhancement. One challenge is to assess invisible geomorphosites that are widespread in urban context. To this aim, we reworked the attributes describing the Value of a site for Geotourism in order to build up a specific methodology for the analysis of the urban geomorphological heritage.

To resolve long-standing problems with the stratigraphy of the Conasauga Group and the Rome Formation on the Copper Creek fault block near Oak Ridge National Laboratory (ORNL), an 828.5-m-deep test borehole was drilled. Continuous rock core was recovered from the 17.7- to 828.5-m-deep interval; temperature, caliper, neutron, gamma-ray, and acoustic (velocity and televiewer) logs were obtained. The Conasauga Group at the study site is 572.4 m thick and comprises six formations that are - in descending stratigraphic order - Maynardville Limestone (98.8 m), Nolichucky Shale (167.9 m), Maryville Limestone (141.1 m), Rogersville Shale (39.6 m), Rutledge Limestone (30.8 m), and Pumpkin Valley Shale (94.2 m). The formations are lithologically complex, ranging from clastics that consist of shales, mudstones, and siltstones to carbonates that consist of micrites, wackestones, packstones, and conglomerates. The Rome Formation is 188.1 m thick and consists of variably bedded mudstones, siltstones, and sandstones. The Rome Formation thickness represents 88.1 m of relatively undeformed section and 100.0 m of highly deformed, jumbled, and partially repeated section. The bottom of the Rome Formation is marked by a tectonic disconformity that occurs within a 46-m-thick, intensely deformed interval caused by motion along the Copper Creek fault. Results from this study establish the stratigraphy and the lithology of the Conasauga Group and the Rome Formation near ORNL and, for the first time, allow for the unambiguous correlation of cores and geophysical logs from boreholes elsewhere in the ORNL vicinity. 45 refs., 26 figs., 2 tabs

Life cycle assessment of urban waste management: energy performances and environmental impacts. The case of Rome, Italy.

2008-12-01

Landfilling is nowadays the most common practice of waste management in Italy in spite of enforced regulations aimed at increasing waste pre-sorting as well as energy and material recovery. In this work we analyse selected alternative scenarios aimed at minimizing the unused material fraction to be delivered to the landfill. The methodological framework of the analysis is the life cycle assessment, in a multi-method form developed by our research team. The approach was applied to the case of municipal solid waste (MSW) management in Rome, with a special focus on energy and material balance, including global and local scale airborne emissions. Results, provided in the form of indices and indicators of efficiency, effectiveness and environmental impacts, point out landfill activities as the worst waste management strategy at a global scale. On the other hand, the investigated waste treatments with energy and material recovery allow important benefits of greenhouse gas emission reduction (among others) but are still affected by non-negligible local emissions. Furthermore, waste treatments leading to energy recovery provide an energy output that, in the best case, is able to meet 15% of the Rome electricity consumption.

Aiding and Abetting: The Responsibility of Business Leaders under the Rome Statute of the International Criminal Court

Caspar Plomp

2014-08-01

Full Text Available While no business leaders have yet been charged before the International Criminal Court (ICC, such future proceedings will typically be conducted with reference to the accessorial mode of liability of aiding and abetting, under Article 25(3(c of the Rome Statute of the ICC. There exist diverse and competing interpretations of Article 25(3(c. This paper aims to advocate the creation of a dominant interpretation of Article 25(3(c and, consequently, to the clarification of the potential responsibility of business leaders who aid or abet crimes under the jurisdiction of the Rome Statute, in two ways. First, it asks whether Article 25(3(c can be interpreted in harmony with the dominant practice on aiding and abetting in international criminal law generally. Second, it presents a case study on the provision of arms by the Russian corporation Rosoboronexport to the Syrian government, which is likely to have committed crimes against humanity since March 2011 and war crimes since mid-2012. The theoretical conclusions are applied to a discussion on the potential criminal responsibility of the Director General of Rosoboronexport for aiding and abetting the commission of international crimes by high-level Syrian officials.

1998-01-01

The study of phenomena related to the quantum behavior of macroscopic systems is subjected to new efforts both from theoretical and experimental point of view. The validity in fact of the description of macroscopic systems given by Quantum Mechanics is still under test, especially for what concerns the macrorealistic interpretation of the real world and the influence of dissipation on quantum systems. Many groups tried in the last few years to realize an experimental set-up to perform an MQC experiment; the intrinsic dissipation however limited the possibility to fulfill the experimental requirements. The technology for realizing high quality Josephson Junctions is now so advanced that in principle the tests proposed in the last ten years can hopefully performed with success. In the following we will present a short description of the basic principles for an MQC experiment, with special emphasis on the experiment planned by the Rome group. (author)

Some recent epidemiological studies suggest an association between lymphatic and haematopoietic cancers and residential exposure to high frequency electromagnetic fields (100 kHz-300 GHz) generated by radio and television transmitters. Vatican Radio, a very powerful radio station transmitting all over the world (up to 600 kW) is located in Santa Maria di Galeria, in the northern suburbs of the city of Rome. Electric field measurements in the proximity of the radio station ranged between 1.5 and 25 V/m. In the 10 km area around the station, with 60.182 residents (1999), leukaemia mortality among adults (> 14 years, 40 cases) in the period 1987-98 and childhood leukaemia incidence in the period 1987-99 (8 cases) were evaluated. The analysis (Stone's conditional test) was performed computing observed and expected cases (reference: population of Rome) in 5 bands of increasing radius (2 km width). The risk of childhood leukaemia was higher than expected within 6 km from the station (Standardized Incidence Ratio = 217; 95% Confidence Interval 99-405). Stone's test showed a significant decrease in risk with increasing distance both for male adult mortality (p-value = 0.03) and for childhood incidence (p-value = 0.04). A Score test, showed a significant decrease in risk of childhood incidence as function of the distance. The main limitations of this study are the small number of observed cases and the use of distance as a proxy for RF exposure. Further research will require a systematic campaign of electromagnetic field measurements to allow better assessment of the population exposure.

The sudden death of Alaric I (c. 370-410AD), the vanquisher of Rome: A tale of malaria and lacking immunity.

Alaric I (c. 370-410AD), King of the Visigoths, sacked Rome for the second time in over eight centuries of history. Historians suggest that malaria, probably contracted either in Rome or in the Pontine Marshes, was responsible for his sudden death in Cosenza (Calabria) in the autumn of 410AD, where he was allegedly buried in the River Busento. In this article, we aim to examine this hypothesis through a full pathographic reassessment of the most likely cause of Alaric's demise. To achieve this, we resorted to a dual philological-medical approach: clinical likelihood and malaria seasonality coupled with primary historical sources (mainly Jordanes' work De origine actibusque Getarum) and the reconstruction of the itineraries followed by Alaric and his army after the sack of Rome. Sudden death is caused by several factors. The possibility that Alaric died of a cardiovascular disease was discarded since no description of potentially pathological signs emerged from the available sources. Given his lack of semi-immunity, falciparum malaria was considered as the most likely cause of his demise. It took him over two months to reach the coasts of Calabria during the peak of malaria's transmission (summer-autumn). During the march, Alaric did not suffer from recurrent fevers or other ailments, which would have been reported by historians. The scenario emerging from this multidisciplinary reanalysis allows us to hypothesise that Plasmodium falciparum malaria, contracted during his journey through Calabria, was the most likely candidate responsible for Alaric's unexpected demise.

Ground stability of the built environment of the city of Rome in central Italy has been extensively investigated in the last years by using Interferometric Synthetic Aperture Radar (InSAR), with focus on deformation of both the monuments of the historic centre (e.g., [1-2]) and the southern residential quarters (e.g., [3]). C-band ERS-1/2 and ENVISAT ASAR time series deformation analyses brought evidence of overall stability across the town centre, except for localized deformation concentrated in areas geologically susceptible to instability (e.g. western slope of the Palatine Hill), whereas clear subsidence patterns were detected over the compressible alluvial deposits lying in proximity of the Tiber River. To retrieve an updated picture of stability and subsidence across the city, we analysed a time series of 32 COSMO-SkyMed StripMap HIMAGE, right-looking, ascending mode scenes with an image swath of 40 km, 3-m resolution and HH polarization, acquired between 21 March 2011 and 10 June 2013, with repeat cycle mostly equal to 16 days. Persistent Scatterer Interferometry (PSI) processing was undertaken by using the Stanford Method for Persistent Scatterers (StaMPS) as detailed in [4], and more than 310,000 radar targets (i.e. PS) were identified, with an average target density of over 2,800 PS/km2. The performance of StaMPS to retrieve satisfactory PS coverage over the urban features of interest was assessed against their orientation and visibility to the satellite Line-Of-Sight, as well as their conservation history throughout the biennial investigated (2011-2013). In this work we discuss effects due to local land cover and land use by exploiting the Global Monitoring for Environment and Security (GMES) European Urban Atlas (IT001L) of Rome at 1:10,000 scale, thereby also evaluating the capability of the X-band to spatially resolve targets coinciding with man-made structures in vegetated areas. Based on this assessment, our PSI results highlight those environmental

Vertical distribution of Saharan dust over Rome (Italy): Comparison between 3-year model predictions and lidar soundings

Mineral dust particles loaded into the atmosphere from the Sahara desert represent one major factor affecting the Earth's radiative budget. Regular model-based forecasts of 3-D dust fields can be used in order to determine the dust radiative effect in climate models, in spite of the large gaps in observations of dust vertical profiles. In this study, dust forecasts by the Tel Aviv University (TAU) dust prediction system were compared to lidar observations to better evaluate the model's capabilities. The TAU dust model was initially developed at the University of Athens and later modified at Tel Aviv University. Dust forecasts are initialized with the aid of the Total Ozone Mapping Spectrometer aerosol index (TOMS AI) measurements. The lidar soundings employed were collected at the outskirts of Rome, Italy (41.84°N, 12.64°E) during the high-dust activity season from March to June of the years 2001, 2002, and 2003. The lidar vertical profiles collected in the presence of dust were used for obtaining statistically significant reference parameters of dust layers over Rome and for model versus lidar comparison. The Barnaba and Gobbi (2001) approach was used in the current study to derive height-resolved dust volumes from lidar measurements of backscatter. Close inspection of the juxtaposed vertical profiles, obtained from lidar and model data near Rome, indicates that the majority (67%) of the cases under investigation can be classified as good or acceptable forecasts of the dust vertical distribution. A more quantitative comparison shows that the model predictions are mainly accurate in the middle part of dust layers. This is supported by high correlation (0.85) between lidar and model data for forecast dust volumes greater than the threshold of 1 × 10-12 cm3/cm3. In general, however, the model tends to underestimate the lidar-derived dust volume profiles. The effect of clouds in the TOMS detection of AI is supposed to be the main factor responsible for this effect

Both active and passive tobacco smoke is carcinogenic. In the last years the most important countries of European Community developed and passed smoke-free public places and smoke-free workplace legislations. The aim of this study was to investigate the real application of smoking ban in bars and restaurants of Rome and to value social, economic and health effects caused by the application of the law. The study was carried out in 200 public places (100 restaurants and 100 bars) with an inspection of the sites and the administration of a questionnaire to the managers of the public places. Results demonstrate that smoking ban in public places is widely respected and that the application of the law had a very positive impact on the quality of life and health of workers and general population.

Geoheritage studies have been highly intensified and diversified in recent years. This field of research has a strong applicability, especially in interdisciplinary and sustainable forms of tourism. For this purpose the most modern technologies are used for supporting the dissemination of research results, in particular for educational purposes (Kenteris et al., 2011 and references therein). This is the case of smartphone and tablet applications developed by the Institute of Geography and Sustainability of Lausanne University (IGD), devoted to geotourist itineraries. This work presents the application developed for the city of Rome, based on the itinerary proposed by the Earth Sciences Department of the Sapienza University (Del Monte et al., 2013; Pica et al., 2015). The Aeterna Urbs, with more than 3000 years of historical development, is a very good place to develop urban geotourism, especially because most of the cultural places are related to morphological features (Pica et al., 2015). As shown by the Geoguide Lausanne (Reynard et al., 2015) - a virtual itinerary showing the relationships between geology/geomorphology, climate/hydrology, and urban development in Lausanne (Switzerland) - and TOURinSTONES - a virtual guide on the rocks used for the construction of urban monuments and infrastructures in the city of Turin (Italy) - the urban context has the advantage of easily showing the links between natural features and human activities. From a technical point of view the application is an updated version of Geoguide Lausanne using jQuery Mobile as development framework, which allowed for increasing the usability and solved some gaps of the previous versions. The contents are organized the same way as for the Geoguide Lausanne, proposing three educational themes, an itinerary arranged in georeferenced stops shown by images and described in their characterizing aspects. The themes are Geology, History and Legends. By means of the relationships between them they

Highlights: • Geochemical study of black crusts developed on three monuments located in Milan, Florence and Rome. • Trace element composition of the black crusts is greatly influenced by anthropogenic pollution. • Geochemical characterization of black crusts can be used as a reliable indicator of environmental pollution. - Abstract: This work presents results from a petrographic, morphological and chemical study of the black crusts developing on monuments in three Italian cities, the Cathedral of Milan, the Cathedral of St. Maria del Fiore in Florence, and the Vittoriano Monument in Rome. Black crusts (BCs) were studied with traditional techniques such as optical microscopy (OM), scanning electron microscopy coupled with energy-dispersive X-ray spectrometry (SEM-EDS) and infrared spectroscopic techniques (FT-IR), in combination with laser ablation inductively coupled mass spectrometry (LA-ICP-MS), which has shown itself to be particularly useful in determining concentrations of heavy metals in BCs. Although the BCs of the three monuments show general enrichment in heavy metals with respect to the substrate (S), interesting differences were observed among them. The BCs from Milan are the richest in heavy metals, particularly Pb and Zn, reflecting the severe air pollution of this very large city, which, in addition to its intense traffic, is located in the most highly industrialized area of Northern Italy. The BCs from the south-eastern side of the Cathedral of St. Maria del Fiore in Florence, facing a pedestrian area, show little enrichment in heavy metals, and those from the Vittoriano Monument in Rome, which is exposed to intense road traffic, display variable enrichment, attributable to mobile emission sources. Results show that the various enrichment trends in heavy metals observed in the BCs of these three monuments are due to many factors: various sources of anthropogenic pollution, sampling height, exposure, orientation, and the shape of the deposition

Cardio-oncology is a relatively new discipline that focuses on the cardiovascular sequelae of anti-tumour drugs. As any other young adolescent discipline, cardio-oncology struggles to define its scientific boundaries and to identify best standards of care for cancer patients or survivors at risk of cardiovascular events. The International Colloquium on Cardio-Oncology was held in Rome, Italy, 12–14 March 2014, with the aim of illuminating controversial issues and unmet needs in modern cardio-oncology. This colloquium embraced contributions from different kind of disciplines (oncology and cardiology but also paediatrics, geriatrics, genetics, and translational research); in fact, cardio-oncology goes way beyond the merging of cardiology with oncology. Moreover, the colloquium programme did not review cardiovascular toxicity from one drug or the other, rather it looked at patients as we see them in their fight against cancer and eventually returning to everyday life. This represents the melting pot in which anti-cancer therapies, genetic backgrounds, and risk factors conspire in producing cardiovascular sequelae, and this calls for screening programmes and well-designed platforms of collaboration between one key professional figure and another. The International Colloquium on Cardio-Oncology was promoted by the Menarini International Foundation and co-chaired by Giorgio Minotti (Rome), Joseph R Carver (Philadelphia, Pennsylvania, United States), and Steven E Lipshultz (Detroit, Michigan, United States). The programme was split into five sessions of broad investigational and clinical relevance (what is cardiotoxicity?, cardiotoxicity in children, adolescents, and young adults, cardiotoxicity in adults, cardiotoxicity in special populations, and the future of cardio-oncology). Here, the colloquium chairs and all the session chairs briefly summarised what was said at the colloquium. Topics and controversies were reported on behalf of all members of the working group

Meteorological events in the lower atmosphere can affect the ionosphere by electromagnetic and mechanical processes. One type of the latter ones is the internal atmospheric gravity waves (AGWs) which can often be generated by thunderstorms. According to a Superposed Epoch Analyses (SEA) using the time series of the critical frequency (foEs) and virtual height (h'Es) of the sporadic E layer and WWLLN (World Wide Lightning Location Network) lightning data over the ionospheric station of Rome (41.9° 12.5°) there is a statistically significant decrease in the foEs of the sporadic E layer after the time of the lightnings. This may indicate a sudden decrease in the electron density of the sporadic E layer associated to lightnings. In order to understand the physical explanation for this phenomenon further studies are performed as follows: a SEA for different seasons and for daytime - nightime lightnings separately. Direction of arrival of thunderstorms is also taken into account.

Full Text Available A scale-invariance analysis of space and time rainfall events monitored by meteorological radar over the area of Rome (Italy is proposed. The study of the scale-invariance properties of intense precipitation storms, particularly important in flood forecast and risk mitigation, allows to transfer rainfall information from the large scale predictive meteorological models to the small scale hydrological rainfall-runoff models. Precipitation events are monitored using data collected by the polarimetric Doppler radar Polar 55C (ISAC-CNR, located 15 km Southeast from downtown. The meteorological radar provides the estimates of rainfall intensity over an area of about 10 000 km2 at a resolution of 2×2 km2 in space and 5 min in time. Many precipitation events have been observed from autumn 2001 up to now. A scale-invariance analysis is performed on some of these events with the aim at exploring the multifractal properties and at understanding their dependence on the meteorological large-scale conditions.

Full Text Available The Camera di Commercio of Rome, created in 1809, has always been closely connected with the commercial, industrial, economic and touristic reality of the city. According to these features, the Camera would need for its library and its documentation center to have an additional interface with its users and to have an effective tool to play his mission. Despite the economic difficulties have not allowed the realization, a detailed project of the structure, whose name should have been 'Bibliocentro', was done. It provides the following qualities: Thematic nature, Utilities, Usability, Visibility, Activities, Interactivity and Historicity. The bibliographic collection and media should be strongly focused on the issues of the institutional activities, along with the complete collection of all publications edited by the Camera. The collection should be ordered and indexed according to the Dewey Decimal Classification. The project also provides for the membership of Bibliocentro to the National Libraries System, to ensure visibility and accessibility.

The Rome IV Committee introduced a major change in the classification of functional gastrointestinal disorders, proposing a more restrictive definition of gastroesophageal reflux disease (GERD). It was suggested that hypersensitive esophagus (HE) may sit more firmly within the functional realm. It was suggested that GERD diagnosis should be based upon abnormal acid exposure time (AET) only, implying no advantage of impedance-pH over pH monitoring. Symptom association probability (SAP), symptom index (SI) and heartburn relief with proton pump inhibitor (PPI) therapy were regarded as unreliable, whereas a lack of response to PPI was considered as evidence of functional heartburn. These assumptions are contradicted by numerous studies showing the clinical relevance of weakly acidic refluxes and the diagnostic utility of SAP, SI and new impedance parameters, namely the post-reflux swallow-induced peristaltic wave (PSPW) index and the mean nocturnal baseline impedance (MNBI). The PSPW index and MNBI provide significant diagnostic advantage, particularly in patients with normal AET who can be classified as HE when both parameters are abnormal, even though SAP and SI are negative. Visceral pain modulators are recommended by the Rome IV Committee despite scanty evidence of efficacy, but a positive outcome with medical or surgical anti-reflux treatment has been reported by several studies of HE patients. Therefore, we believe that patients with endoscopy-negative heartburn should be investigated by means of impedance-pH monitoring with analysis of PSPW index and MNBI: such an approach provides accurate identification of HE cases, who remain, in our opinion, within the realm of GERD and should be treated accordingly.

Full Text Available The archaeological site of Ostia Antica hosts the ruins of the ancient roman city called Ostia founded in the VII century B.C. near the mouth of Tiber River. The area was strategically important for Rome, not only for the control of the river, but also for some salt marshes (Ostia Pound. During the XIX century, the whole area was reclaimed and the salt production stopped. Nowadays drainage canals and pumps avoid the flood of zones placed below sea level, keeping dewatering below the ground surface. In February 2014, the site was largely flooded after an exceptional rainfall event and the Superintendence for Archaeological Heritage of Rome ordered the closure for 15 days. Few months later (July 2014 a groundwater monitoring project started with the aim of studying the aquifer response to local rainfall and prevent future damage and groundwater flooding. The activity consisted in water-table monitoring, groundwater electrical conductivity (EC and temperature continuous measurements, coupled with chemical analysis of major ions. Preliminary results shows the link between water table fluctuations and rainfall distributions. The average elevation of the archaeological area is about 2,5 m a.s.l. and the local water-table depth is of about 0,5 m a.s.l.; groundwater flows from the Tiber River to the reclaimed area according to regional flowpath. Groundwater sampled from three wells is Ca-HCO3 freshwater (600 - 1000 μS/cm, while the sample collected from a well located close to ancient salt storage warehouse (now Ostia Antica museum, is Na-Cl brackish water (about 4000 μS/cm. The chemical evolution of groundwater from summer to winter suggested a possible lateral inflow from the Tiber River, affected by salt-wedge intrusion. The inflow of Ca-Cl, SO4 Tiber’s water with an intermediate salinity could determine salinization of Ca-HCO3 freshwaters and refreshing of Na-Cl brackish water.

Data assimilation techniques are methods to limit the growth of errors in a dynamical model by allowing observations distributed in space and time to force (nudge) model solutions. They have become common for meteorological model applications in recent years, especially to enhance weather forecast and to support air-quality studies. In order to investigate the influence of different data assimilation techniques on the meteorological fields produced by RAMS model, and to evaluate their effects on the ozone and PM10 concentrations predicted by FARM model, several numeric experiments were conducted over the urban area of Rome, Italy, during a summer episode.

Full Text Available In recent years, researchers and practitioners are increasingly interested in the role and influence of the forms of business organization on the economy and society. Interpretations of the role of companies in the modern period, ranging from enthusiastic support (as the most important invention of capitalism, an explanation of the Western civilization’s expansion to moderate and often critical positions, where the company is seen as a solution, not necessarily optimal, to market imperfections. On the other hand, we often ponder upon the explanation of political, administrative and infrastructural success of ancient Rome: the state or the enterprise (the private initiative? Closer to our time, we rediscover with amazement that the "dark" Middle Ages are not at all dark and lacking in progress, at least in terms of capitalist organization and logic. The development of trade in the two poles of medieval Europe (the Mediterranean and the BaltoScandinavian area, of industry and trade in the North-Western quadrant (Flanders and neighbouring regions, was concurrent with the improvement of organizational forms of business, with the diversity and flexibility of entrepreneurial or even corporate frameworks. Of course, the study of historical sources (ancient or medieval cannot provide direct answers or solutions to the questions of modern society, because the challenges of today are rather different to those of the past. On the other hand, understanding history can help companies to build a more complete and a wiser enterprise functionality and role in the modern society, to reformulate the questions and to find new solutions. Our paper, with a clear juridical perspective on economic history, focuses on the organization of firms in ancient Rome and medieval Europe, tries to provide examples, useful interpretations and diverse solutions to the problems of contemporary society and economy.

Air quality high resolution simulations of Italian urban areas with WRF-CHIMERE

Falasca, Serena; Curci, Gabriele

2017-04-01

The new European Directive on ambient air quality and cleaner air for Europe (2008/50/EC) encourages the use of modeling techniques to support the observations in the assessment and forecasting of air quality. The modelling system based on the combination of the WRF meteorological model and the CHIMERE chemistry-transport model is used to perform simulations at high resolution over the main Italian cities (e.g. Milan, Rome). Three domains covering Europe, Italy and the urban areas are nested with a decreasing grid size up to 1 km. Numerical results are produced for a winter month and a summer month of the year 2010 and are validated using ground-based observations (e.g. from the European air quality database AirBase). A sensitivity study is performed using different physics options, domain resolution and grid ratio; different urban parameterization schemes are tested using also characteristic morphology parameters for the cities considered. A spatial reallocation of anthropogenic emissions derived from international (e.g. EMEP, TNO, HTAP) and national (e.g. CTN-ACE) emissions inventories and based on the land cover datasets (Global Land Cover Facility and GlobCover) and the OpenStreetMap tool is also included. Preliminary results indicate that the introduction of the spatial redistribution at high-resolution allows a more realistic reproduction of the distribution of the emission flows and thus the concentrations of the pollutants, with significant advantages especially for the urban environments.

Full Text Available In the last decade, many investigations and studies have appeared on Renaissance style architectural episodes in Calabria and yet, nevertheless, something always appears to be missing.  It might be identified, however,  if we look beyond the borders of Calabria, towards the predominant cities towards which the long toe of Italy was drawn for both political and commercial reasons. As the title suggests, and without taking anything from the contribution of the local 15th-16th cent. schools and the original work of architects and stonemasons, it is necessary to look at the principal  sources of Calabrian Renaissance architecture (Neapolitan and Roman sources. These sources were reviewed and ‘naturalized’ through the filters of building tradition, materials, style and time-honoured  local habits. Above all, it is fundamental to look ‘nearby’, towards closer sources, even if identification is paradoxically difficult due to the poor knowledge of Neapolitan Renaissance architecture, especially if we think about the great quantity of research which has always focused on Florence, Rome and Venice.

Interpreting Sustainability through Co-Evolution: Evidence from Religious Accommodations in Rome

Paola M. A. Paniccia

2017-12-01

Full Text Available In recent decades, concepts such as sustainability, innovation, and competitiveness have become fundamental for the development of tourist destinations, and thus, particularly, for the generation of value co-creation processes. To understand the role of tourism firms in these processes, more theoretical and empirical research is required. This paper addresses this need by examining the increasing role played by religious accommodations, adopting a co-evolutionary approach to sustainability and the resulting value co-creation processes. The study focuses on the dynamics of the relationship between this new hospitality model, territories, and tourists, through the analysis of six case studies localized in the historic centre of Rome (Italy. Findings show that religious accommodations can be considered as a new sustainability-oriented hospitality model that, by creating effective multi-level co-evolutionary adaptations with its territory and tourists, positively affects sustainable development as well as the generation of value co-creation processes. The paper contributes significantly both to sustainability literature and to the study of new hospitality models. Thus, theoretical and managerial implications emerge, together with suggestions for future research.

Accurate air temperature observations are important for urban meteorology, for example to study the urban heat island and adverse effects of high temperatures on human health. The number of available temperature observations is often relatively limited. A new development is presented to derive temperature information for the urban canopy from an alternative source: cell phones. Battery temperature data were collected by users of an Android application for cell phones (opensignal.com). The application automatically sends battery temperature data to a server for storage. In this study, battery temperatures are averaged in space and time to obtain daily averaged battery temperatures for each city separately. A regression model, which can be related to a physical model, is employed to retrieve daily air temperatures from battery temperatures. The model is calibrated with observed air temperatures from a meteorological station of an airport located in or near the city. Time series of air temperatures are obtained for each city for a period of several months, where 50% of the data is for independent verification. Results are presented for Buenos Aires, London, Los Angeles, Paris, Mexico City, Moscow, Rome, and Sao Paulo. The evolution of the retrieved air temperatures often correspond well with the observed ones. The mean absolute error of daily air temperatures is less than 2 degrees Celsius, and the bias is within 1 degree Celsius. This shows that monitoring air temperatures employing an Android application holds great promise. Since 75% of the world's population has a cell phone, 20% of the land surface of the earth has cellular telephone coverage, and 500 million devices use the Android operating system, there is a huge potential for measuring air temperatures employing cell phones. This could eventually lead to real-time world-wide temperature maps.

A 3D GIS METHOD APPLIED TO CATALOGING AND RESTORING: THE CASE OF AURELIAN WALLS AT ROME

Directory of Open Access Journals (Sweden)

M. Canciani

2013-07-01

Full Text Available The project involves architecture, archaeology, restoration, graphic documentation and computer imaging. The objective is development of a method for documentation of an architectural feature, based on a three-dimensional model obtained through laser scanning technologies, linked to a database developed in GIS environment. The case study concerns a short section of Rome's Aurelian walls, including the Porta Latina. The city walls are Rome's largest single architectural monument, subject to continuous deterioration, modification and maintenance since their original construction beginning in 271 AD. The documentation system provides a flexible, precise and easily-applied instrument for recording the full appearance, materials, stratification palimpsest and conservation status, in order to identify restoration criteria and intervention priorities, and to monitor and control the use and conservation of the walls over time. The project began with an analysis and documentation campaign integrating direct, traditional recording methods with indirect, topographic instrument and 3D laser scanning recording. These recording systems permitted development of a geographic information system based on three-dimensional modelling of separate, individual elements, linked to a database and related to the various stratigraphic horizons, the construction techniques, the component materials and their state of degradation. The investigations of the extant wall fabric were further compared to historic documentation, from both graphic and descriptive sources. The resulting model constitutes the core of the GIS system for this specific monument. The methodology is notable for its low cost, precision, practicality and thoroughness, and can be applied to the entire Aurelian wall and to other monuments.

A key point for cultural heritage protection in many modern cities is to prevent damaging of historical monuments from urbanization disturbances, such as road and subway traffic vibrations. A typical dilemma is whether to focus on the effects of short-term vibrations due to construction activities or on the consequences of long-term traffic induced vibrations. Both case s present practical difficulties in both monitoring and data analysis procedures. Besides, specific standards do not provide indications neither on how to extract meaningful features from data, nor on how to identify proper strategic decisions for an effective maintenance of monuments. In this paper, an example of state - of - the - art monitoring system is presented with its application to the continuous trigger free dynamic monitoring of the Flavian Amphitheater , widely known as the Colosseum , in Rome . The installation of the monitoring system , composed of wireless accelerometers located on the top portion of the North façade of the Monument , has allowed to study all the features of recorded vibrations, beyond the usually considered peaks . The system architecture, the wireless protocol and the processing of the data are described in detail in this paper . A discussion on the data collected during a full year of monitoring is presented , with focus on statistical representation s of the dynamic response, such as fractiles of the peak acceleration s, which are meaningful and synthetic indicator s of the effects induced on the Monument by external actions of both natural and man-made nature.

Indoor and outdoor concentrations of polycyclic aromatic hydrocarbons (PAHs) associated with PM2.5 particles were monitored in three microenvironments (schools, homes and offices) in the city of Rome, Italy, between winter 2011 and summer 2012. Molecular signatures and indoor/outdoor concentration ratios of PAHs were investigated, with special emphasis on carcinogenic congeners. At indoor locations, total PAHs ranged, on average, from 1.8 to 8.4 ng/m3 in winter and from 0.30 to 1.35 ng/m3 in spring/summer. Outdoors, total PAH concentrations were found to reach 6.3-17.9 ng/m3 in winter and 0.42-1.74 ng/m3 in spring-summer. Indoors, the concentration of benzo[a]pyrene (BaP) was as high as 1.1 ng/m3 in winter and below 0.1 ng/m3 in the warm season, independently of site type; the yearly average remained below the European guideline value. The indoor/outdoor concentration ratios of individual compounds were lower than one for most of congeners, suggesting that outdoor sources were predominant. Nonetheless, the percentages of PAH compounds changed with sites and seasons; in particular, in spring/summer, the concentration of BaP at our sites was more than twice that recorded at the regional network stations.

Entertainment in View of Politicians in Ancient Greece and Rome

2012-01-01

Full Text Available The article discloses the cultural and social conditions of the entertainment phenomenon in Ancient Greece and Rome and the attitude of the authorities to it. The appearance of entertainment is closely related to the worship of cult of Gods. It is shown that the Romans being more materialistic and pragmatic paid less attention to spiritual entertainment than Greeks who fostered dramatic performances. Greek rulers and noblemen saw relaxational and educational function of the entertainment and also considered it as reducing tension and promoting solidarity. However, they did not intrude into its practical organization and had only a monitoring position, whereas the Romans were more interested in daily life and its bodily pleasures. Accordingly in recreational activities – games there dominated the spirit of competition, especially the gladiators games, which were bloody and cruel, but heated passions of spectators whose majority was comprised of plebs. There is shown that the authorities considered the entertainment as an effective tool to reach political aims, especially for gaining the support of commons in various elections, so they financed gladiators’ performances generously.This tradition is still topical in the flow of years. These days it has become the constituent part of the political marketing.

The Italian political unification is a process starting in 1861. The next ten years, until the freeing of Rome, are a period of strong changes because the the new nation starts by heavier backwardness conditions compared to other European nations.

The basic conditionings that bound the new nation are summarized in some causes: an underdeveloped economic system where there are areas of industrial development; a significant shortage of mineral and energy resources; and an urban structure that is still that of the sixteenth century, the last brightness period of the Italian cities. The same internal communication system is composed of a basic road network which is still one of Roman origin and of isolated sections of rail network, with few links among the pre-unity nations.

Particular attention should be paid on the impact of the economic processes on the cities: they have a strong impact on European cities since the early nineteenth century, but their impact on Italian cities (beginning from the main northern cities, Milan and Turin is more limited, if compared with the transformations concerning other continental cities.

The unification starting from 1861 imposes additional critical elements, because the Italian urban structure is not ready to the event, particularly for the choice of the capital city. A city that can rightfully define itself as capital exists, and it is Turin; but it is peripheral to the rest of the Italian territory. Furthermore there is an in pectore capital city, Rome, that is the symbolic centre of the Italian history. But the city has to wait another ten years to join to the rest of Italy. The solution is to temporarily move the capitol to Florence, even if nobody explicitly says it to Florentines! The step from Turin to Florence, and from Florence to Rome sets in motion a complex organizational mechanism and a significant money‘s amount, invested in the effort to bring the two cities to the new role

A hybrid technique, based on mode summation and finite differences, is used to simulate the ground motion induced in the city of Rome by the January 13, 1915, Fucino (Italy) earthquake (M=6.9). The technique allows us to take into consideration source, path, and local soil effects. The results of the numerical simulations are used for a comparison between the observed distribution of damage in Rome, and certain quantities related to the computed ground motion. These quantities are those commonly used for engineering purposes, e.g. the peak ground acceleration, the maximum response of a simple oscillator, and the so-called ''total energy of ground motion'' which is related to the Arias Intensity. Integral quantities of the computed time-series, such as the total energy of ground motion, are in good agreement with the observed distribution of damage and turn out to give a good representation of the ground motion. From the computation of spectral ratios, it has been recognised that the presence of a near-surface layer of rigid material is not sufficient to classify a location as a ''hard-rock site'' when the rigid material has a sedimentary complex below it. This is because the underlying sedimentary complex causes amplifications due to resonances. Within sedimentary basins, incident energy in certain frequency bands can also be shifted from the vertical, into the radial component of motion. This phenomenon is very localized, both in frequency and space, and closely neighboring sites can be characterized by very large differences in the seismic response, even if the lateral variations of local soil conditions are relatively smooth.

Highlights: • A systematic approach for energy management of complex structures is proposed. • Technological systems of Leonardo da Vinci Airport of Rome are described. • A multi-year consumption analysis highlights the most energy-consuming sectors. • The “Smart Grid” prototype project inherent to T1 Terminal is presented. • Wind and photovoltaic plants are designed and discussed to test the smart storage. - Abstract: Because of the growing need for efficient energy production systems, energy policies promoted in recent years have also involved complex structures, like airports. This paper proposes the implementation of an energy management system for a very energy-consuming structure, composed of different power plants and many energy consumers: the Leonardo da Vinci International Airport of Rome. In this study, the examination of historical data related to airport electric power, thermal energy and fuel consumption is discussed, starting with the analysis of the production energy plants, mainly based on a combined heat and power system. Furthermore, pioneering solutions are proposed, not only to cover airport energy requirements, but also to test the safety and reliability of innovative load management systems. For this reason, the choice of the Leonardo da Vinci management company, oriented to install a smart storage in order to manage the bidirectional energy flows by consumers and producers, is justified. Such innovative energy procurement systems are examined, with the goal of achieving greater penetration of renewable sources: mini and micro wind power plants and high concentrator photovoltaic plants.

Between 1907 and 1908, Maria Montessori's (1870-1952) educational method was elaborated at the Children's Houses of the San Lorenzo district in Rome. This pioneering experience was the basis for the international fame that came to Montessori after the publication of her 1909 volume dedicated to her "Method." The "Montessori Method" was considered by some to be scientific, liberal, and revolutionary. The present article focuses upon the complex contexts of the method's elaboration. It shows how the Children's Houses developed in relation to a particular scientific and cultural eclecticism. It describes the factors that both favored and hindered the method's elaboration, by paying attention to the complex network of social, institutional, and scientific relationships revolving around the figure of Maria Montessori. A number of "contradictory" dimensions of Montessori's experience are also examined with a view to helping to revise her myth and offering the image of a scholar who was a real early-twentieth-century prototype of a "multiple" behavioral scientist.

Since the dawn of medicine, medical rights and ethics have always been one of mankind's concerns. In any civilisation, attention paid to medical laws and ethics depends on the progress of human values and the advancement of medical science. The history of various civilisations teaches that each had its own views on medical ethics, but most had something in common. Ancient civilisations such as Greece, Rome, or Assyria did not consider the foetus to be alive and therefore to have human rights. In contrast, ancient Persians valued the foetus as a living person equal to others. Accordingly, they brought laws against abortion, even in cases of sexual abuse. Furthermore, abortion was considered to be a murder and punishments were meted out to the mother, father, and the person performing it.

Accurate air temperature observations in urban areas are important for meteorology and energy demand planning. They are indispensable to study the urban heat island effect and the adverse effects of high temperatures on human health. However, the availability of temperature observations in cities is often limited. Here we show that relatively accurate air temperature information for the urban canopy layer can be obtained from an alternative, nowadays omnipresent source: smartphones. In this study, battery temperatures were collected by an Android application for smartphones. It has been shown that a straightforward heat transfer model can be employed to estimate daily mean air temperatures from smartphone battery temperatures for eight major cities around the world. The results demonstrate the enormous potential of this crowdsourcing application for real-time temperature monitoring in densely populated areas. Battery temperature data were collected by users of an Android application for cell phones (opensignal.com). The application automatically sends battery temperature data to a server for storage. In this study, battery temperatures are averaged in space and time to obtain daily averaged battery temperatures for each city separately. A regression model, which can be related to a physical model, is employed to retrieve daily air temperatures from battery temperatures. The model is calibrated with observed air temperatures from a meteorological station of an airport located in or near the city. Time series of air temperatures are obtained for each city for a period of several months, where 50% of the data is for independent verification. The methodology has been applied to Buenos Aires, London, Los Angeles, Paris, Mexico City, Moscow, Rome, and Sao Paulo. The evolution of the retrieved air temperatures often correspond well with the observed ones. The mean absolute error of daily air temperatures is less than 2 degrees Celsius, and the bias is within 1 degree

We here report the results of field trials carried out in Rome with the aim to obtain data on the feeding behaviour of Aedes albopictus, in relation to different availability and abundance of putative hosts. Human Blood Index values were found higher than 75% in urban areas, where humans represented the most abundant hosts, and lower than 60% in rural areas, where host alternative to humans were frequent. The overall results confirm the generalist feeding-behaviour shown by this species in its original range of distribution and highlighting its high potential as vector of human pathogens in urban areas of Italy.

Full Text Available This article addresses certain issues related to the enforcement of the Rome II Regulation. The mentioned Regulation was adopted in order to unify, within the European Union, the rules regarding choice of law concerning non-contractual obligations. The application of the Regulation has caused some controversies in jurisprudence, regarding the implications on the national laws and international treaties or conventions. Almost two years after its prescribed date of application, a rigorous analysis of the Regulation’s impact over the case law, both on national and European level is necessary. The purpose of this study is to briefly describe, the research of the two authors regarding the practical effects of the aforementioned Regulation, as well as some judicial problems arisen from its application, mainly relating to the general rule of law, expressed in the fourth Article of the Regulation.

Full Text Available Biosphere-atmosphere interactions were investigated on a sandy dune Mediterranean ecosystem in a field campaign held in 2007 within the frame of the European Projects ACCENT and VOCBAS. The campaign was carried out in the Presidential estate of Castelporziano, a peri-urban park close to Rome. Former campaigns (e.g. BEMA performed in Castelporziano investigated the emission of biogenic volatile organic compounds (BVOC. These campaigns focused on pseudosteppe and evergreen oak groves whereas the contribution of the largely biodiverse dune vegetation, a prominent component of the Mediterranean ecosystem, was overlooked. While specific aspects of the campaign will be discussed in companion papers, the general climatic and physiological aspects are presented here, together with information regarding BVOC emission from the most common plant species of the dune ecosystem. During the campaign regular air movements were observed, dominated by moderate nocturnal land breeze and diurnal sea breeze. A regular daily increase of ozone concentration in the air was also observed, but daily peaks of ozone were lower than those measured in summer on the same site. The site was ideal as a natural photochemical reactor to observe reaction, transport and deposition processes occurring in the Mediterranean basin, since the sea-land breeze circulation allowed a strong mixing between biogenic and anthropogenic emissions and secondary pollutants. Measurements were run in May, when plant physiological conditions were optimal, in absence of severe drought and heat stress. Foliar rates of photosynthesis and transpiration were as high as generally recorded in unstressed Mediterranean sclerophyllous plants. Most of the plant species emitted high level of monoterpenes, despite measurements being made in a period in which emissions of volatile isoprenoids could be restrained by developmental and environmental factors, such as leaf age and relatively low air temperature

There is evidence of adverse health impacts from human exposure to particulate air pollution, including increased rates of respiratory and cardiovascular illness, hospitalizations, and pre-mature mortality. Most recent hypotheses assign an important role to ultrafine particles (UFP) (<0.1 μm) and to associated transition metals (in particular Fe). In a large city like Rome, where many active people spend more than one hour per day in private or public transportation, it may be important to evaluate the level of exposure to harmful pollutants which occurs during urban travelling. In this context, the aim of this work was to examine the relative contribution of different transport modes to total daily exposure. We performed experimental measurements during both morning and evening traffic peak hours throughout the winter season (December 2013–March 2014), for a total of 98 trips. Our results suggest that the lowest UFP exposures are experienced by underground train commuters, with an average number concentration of 14 134 cm −3 , and are largely a reflection of the routes being at greater distance from vehicular traffic. Motorcyclists experienced significantly higher average concentrations (73 168 cm −3 ) than all other exposure classes, and this is most likely a result of the presence of high-concentration and short-duration peaks which do not occur when the same routes are traveled by car. UFP concentrations in subway train environments were found to be comparable to urban background levels. Still, in underground trains we found the highest values of PM 10 mass concentration with a maximum value of 422 μg/m 3 . PM 10 concentration in trains was found to be four and two times higher than what was measured in car and motorbike trips, respectively. Transport mode contribution to total integrated UFP daily exposure was found to be 16.3%–20.9% while travelling by car, 28.7% for motorbike trips, and 8.7% for subway trips. Due to lower exposure times

Full Text Available Through the presentation of two case studies this paper aims to engage the theoretical debate on the persistence of public space in the contemporary city, and focuses the attention on the way people practice these spaces and on the policies which are regulating their uses. Starting from the description of different ways in which some urban spaces in Rome (Italy are used by two different communities of people, one mainly composed by immigrants and the other by young city users, and the diverse ways in which their different practices are seen and tolerated, the aim of this paper is to reflect on public spaces. Observing how city users practice public spaces, and analysing the way in which these practices are considered, are particularly exciting perspectives that can offer an interesting vision of the spatial and social reality of the city and of hegemonic relations which govern it.

Full Text Available Research on the geographical structure of the flora of Podgorica revealed that 85.9% of the species are native, while 14.1% are non-native. This ratio is typical of Mediterranean settlements, where even the most urbanized region reflects the overall character of the surrounding flora. In terms of chorologic groups, the three largest are: eury-Mediterranean (18.2%, cosmopolitan (12.6%, and steno-Mediterranean (8.3%. The percentage of endemic and subendemic plants is also significant (6.8%. Within the group of aliens, species of Asian origin prevail. Comparative analysis of the chorologic spectra of Podgorica, Rome, Patras, and Salonika revealed some similarities.

Full Text Available Functional constipation is very common with heterogeneous symptoms that have substantial impact on patient quality of life as well as medical resources which are rarely reported as life-threatening. The aim of this study is to examine the prevalence and symptoms characteristic of functional constipation (FC by using Rome III diagnostic criteria among tertiary education students with an intention to introduce treatment in the future.Demographic, socio-economics characteristics and symptoms of FC using the Rome III criteria were sought using a questionnaire administered to Malaysian students in a tertiary education setting. Other data obtained were the general health status, lifestyle factors and anthropometric measurements. Using a simple random sampling method, a total of 1662 students were recruited in the study with a response rate of 95.0%. Sampled data are presented as frequency and percentage and stratified accordingly into categories for Chi-square analysis.The prevalence of functional constipation among the students was 16.2%, with a significantly higher prevalence among women (17.4% than men (12.5%. Hard or lumpy stool, incomplete evacuation, anorectal obstruction and straining were reported as the commonest symptoms experienced. Type 3 was the most frequent stool consistency experienced among the constipated individuals (35.2%. Only 4.4% of individuals reported having less than three defecations per week. Using univariable analysis, FC was significantly associated with sex (odds ratio: 1.48, 95% CI: 1.06-2.06 and age group (odds ratio: 1.34, 95% CI: 1.01-1.79 with P value < 0.05 significance level. In multivariate logistic regression analysis, only sex was found significantly associated with FC (adjusted odds ratio: 1.53, 95% CI: 1.08-2.17, P < 0.05.Based on the prevalence rate, constipation is a common problem among tertiary education students (16.2%, with significantly more prevalence among the female respondents.

Full Text Available The aim of the study was to perform a study on the western slope of the Monti Parioli hill (Rome, Italy affected by frequent rock-fall phenomena, such as the one that occurred on 13 November 2007.

This goal was achieved by defining a detailed reconstruction of the stratigraphical, geological and geomechanical structure of the slope and by conducting a back-analysis of the rock-fall event using 2-D and 3-D modeling tools.

The reconstruction of the slope's geological structure, characterized by the presence of two anthropogenic cavity systems, and the characterisation of geomechanical properties of outcropping terrains have been realized by means of a detailed geological survey and a campaign of direct and indirect investigations. Therefore, continuous rotary, coring boreholes up to 60 m, collecting undisturbed samples for laboratory tests and performing direct investigations such as SPTs and pressuremeter tests were carried out. The indirect investigations included electrical tomography surveys, linear surface seismic refraction surveys and seismic cross-hole tests.

Using the reconstructed geological-technical model, it was possible to define the stability conditions of the slope at the time of collapse by using a computational two-dimensional explicit finite difference program (FLAC and a 3-D finite element analysis (FEMLAB.

Full Text Available The authors show the results of an integrated model for risk management of tuberculosis in a sample of sheltered homeless in Rome. Tuberculin skin test (TST was used for evaluating the prevalence of latent infection (LTBI. In TST positives, expectorate was collected and chest X-ray was achieved. Multiple logistic regression analysis was performed to investigate determinants of infection. Out of 288 recruited subjects, 259 returned for the TST reading; 45.56% were positive and referred to a specialized center; 70 accessed the health facility and completed the clinical pathway. The risk factors associated to LTBI were male gender (OR=3.72, age over 60 years (OR=3.59, immigrant status (OR=3.73, and obesity (OR=2.19. This approach, based on an integrated social network, guarantees high adherence to screening (89.93%, allowing patients testing positive for latent tuberculosis infection to be diagnosed and rapidly referred to a specialized center.

Full Text Available Plant disease management may be improved by collecting, storing, manipulating, analysing and displaying epidemiological information using a Geographic Information System (GIS, a useful tool to evaluate plant disease problems in a spatial context. In this study, GIS analysis was applied along with global positioning systems (GPS to integrate field data-collected with the spatial distribution of the pathogen Inonotus rickii. This pathogen provokes a decay of sapwood/heartwood and cankers, determining a progressive crown dieback and structural weakness of the trees, therefore increasing risk of branch breaks and tree failures. It is widespread in tropical and subtropical countries and it has already been recorded in many areas in Rome on Acer negundo, Albizia julibrissin, Koelreuteria paniculata, Celtis australis and Platanus x acerifolia. A survey was carried out in different boulevards of A. negundo and A. julibrissin with the aim of evaluating disease symptoms such as sparse foliage, dead twigs and branches, wood decay and presence of fungal structures. In this survey, I. rickii was recorded also on Robinia pseudoacacia, which is a new host. The study allowed to obtain thematic maps showing the spatial distribution of all infected trees, as well as the presence of anamorph and/or teleomorph structures of the fungus. Moreover, a map representing the incidence of the pathogen in different boulevards was obtained. The usefulness of GIS analysis in studies aimed to support and refine management strategies for disease control in urban trees is discussed.

2013-12-01

Full Text Available This work presents the preliminary results of a groundwater and geothermal model applied to the hydrothermal system of the Tivoli- Guidonia plain, located in the east surroundings of Rome. This area, which is characterized by a thick outcropping travertine deposit, has been an important quarry extraction area since roman age. Today the extraction is in deepening helped by a large dewatering action. By an hydrogeological point of view, the travertine aquifer of the Tivoli- Guidonia Plain, is recharged by lateral discharge in the Lucretili and Cornicolani Mts., and by piping trough important regional faults, located in the basal aquiclude, in the central area of the basin. Piping hydrothermal groundwater is the main contribution on flow in the basin. Preliminary simulations of the groundwater-geothermal model, reproduce quite well the heat and mineralization plumes of groundwater observed in the travertine aquifer.

Abstract:
Background: oral health is an important aspect of well-being. In Italy immigrants can have different access to health care services, and can opt for the national Health Service (nHS and/ or private non- profit health care organizations. The purpose of this study was to develop an instrument to evaluate oral health in the immigrant population of rome and to investigate the differences between two different types of ser- vices: the First observation unit at the department of oral and Maxillo Facial Sciences, at the "Sapienza" university of rome (a nHS affiliate, and a charitable organization, the caritas dental center (cdc.
Methods: a multiple-choice questionnaire was administered between the last trimester of 2006 and the first trimester of 2007. a chi square analysis was performed and the level of significance was set at p<0.05. reSulTS: The sample was composed of 250 people, of which 100 were patients of the cdc and 150 were patients of the nHS. The percentage of non-Italians was 80% (n=80 in the cdc sample, and only 16% (n=25 in the nHS sample. In the cdc, definitive resolving therapies, such as tooth extractions, prevailed (60% v’s 47% nHS; p=0.033. In addition, the frequency of consumption of sugary foods and drinks was significantly higher among cdc patients (31% reported to consume these over 9 times a day compared to nHS patients (11% reporting this consumption.
Discussion: the study shows a substantial under using of the national Health Service for oral health care needs by the immigrant population. The particular composition of the sample, with a high prevalence being of romanian nationality, might reflect specific conditions of this nationality. The results showed that immigrants were satisfied with the health care even though they encountered difficulties in terms of level of communication.

Turning the rumor of May 11, 2011 earthquake prediction In Rome, Italy, into an information day on earthquake hazard

2011-12-01

A devastating earthquake had been predicted for May 11, 2011 in Rome. This prediction was never released officially by anyone, but it grew up in the Internet and was amplified by media. It was erroneously ascribed to Raffaele Bendandi, an Italian self-taught natural scientist who studied planetary motions. Indeed, around May 11, 2011, a planetary alignment was really expected and this contributed to give credibility to the earthquake prediction among people. During the previous months, INGV was overwhelmed with requests for information about this supposed prediction by Roman inhabitants and tourists. Given the considerable mediatic impact of this expected earthquake, INGV decided to organize an Open Day in its headquarter in Rome for people who wanted to learn more about the Italian seismicity and the earthquake as natural phenomenon. The Open Day was preceded by a press conference two days before, in which we talked about this prediction, we presented the Open Day, and we had a scientific discussion with journalists about the earthquake prediction and more in general on the real problem of seismic risk in Italy. About 40 journalists from newspapers, local and national tv's, press agencies and web news attended the Press Conference and hundreds of articles appeared in the following days, advertising the 11 May Open Day. The INGV opened to the public all day long (9am - 9pm) with the following program: i) meetings with INGV researchers to discuss scientific issues; ii) visits to the seismic monitoring room, open 24h/7 all year; iii) guided tours through interactive exhibitions on earthquakes and Earth's deep structure; iv) lectures on general topics from the social impact of rumors to seismic risk reduction; v) 13 new videos on channel YouTube.com/INGVterremoti to explain the earthquake process and give updates on various aspects of seismic monitoring in Italy; vi) distribution of books and brochures. Surprisingly, more than 3000 visitors came to visit INGV

Irritable bowel syndrome (IBS) is one of the most common functional gastroenterological diseases, affecting 11.2 % of people worldwide. Previous studies have shown that probiotic treatment may benefit IBS patients. However, the effect of probiotics and the appropriate type, dose, and treatment duration for IBS are still unclear. The aim of the current study was to assess the efficacy of different probiotic types, doses and treatment durations in IBS patients diagnosed by Rome III criteria via a meta-analysis of randomized controlled trials (RCTs). Medline, EMBASE, and the Cochrane Central Register of Controlled Trials up to October 2015 were searched. RCTs including comparisons between the effects of probiotics and placebo on IBS patients diagnosed by Rome III criteria were eligible. Dichotomous data were pooled to obtain the relative risk (RR) with a 95 % confidence interval (CI), whereas continuous data were pooled using a standardized mean difference (SMD) with a 95 % CI. Twenty-one RCTs were included in this meta-analysis. Probiotic therapy was associated with more improvement than placebo administration in overall symptom response (RR: 1.82, 95 % CI 1.27 to 2.60) and quality of life (QoL) (SMD: 0.29, 95 % CI 0.08 to 0.50), but not in individual IBS symptoms. Single probiotics, a low dose, and a short treatment duration were more effective with respect to overall symptom response and QoL. No differences were detected in individual IBS symptoms in the subgroup analyses. Probiotics are an effective pharmacological therapy in IBS patients. Single probiotics at a low dose and with a short treatment duration appear to be more effective in improving overall symptom response and QoL, but more evidence for these effects is still needed.

The Azienda Sanitaria Locale Roma E (ASL-RME) outpatient clinic is the main reference center in Rome for HIV testing of foreign people. To define the prevalence and incidence of HIV infection among foreign transsexual sex workers attending the center. A cross-sectional, follow-up study was conducted. Between 1993 and 1999, 353 transsexuals attended the ASL-RME. They were from Colombia (n = 208), Brazil (n = 122), and other countries (n = 23). Most of these transsexuals reported having 5 to 10 partners per day. The overall HIV prevalence was 38.2%, which multivariate analysis found to be associated with origin from Brazil and a higher number of sex partners. The observed HIV seroconversion rate was 4.1 per 100 person-years, and non-regular condom use was the only factor related to seroconversion. The data from this study suggest that promotion of safer sex practices and regular condom use still is the main priority among marginalized population subgroups, such as foreign prostitutes, involved in sex activities that put them at risk for HIV infection.

2014-01-01

Full Text Available Internet penetration has created a revolutionary change in people's communication nowadays. By creating immaterial and elusive cyberspace, without borders and limits of communication a three-dimensional territorial concept has been transformed by globalizing social relations and reducing importance of regional or national dimensions. All situations taking place on the Internet also occur somewhere in the reality. Sometimes it is difficult to measure whether the events are random or unrelated to particular events. Technological progress offers new possibilities to change a user's real location either consciously or subconsciously. However, the law is highly territorial in nature. This article focuses on existing conflict of law rules under the EU law and reveals its weaknesses in relation to non-contractual obligations caused by the Internet. Therefore, the author observes core concepts of the applicable law by analyzing the legal notions and information technology concepts and assessing the suitability of regulation in cyberspace. The EU regulation, the doctrine of European and domestic authors as well as the EU case law have been examined. As a result, a number of conclusions have been drawn on the suitability of non-contractual relationships in cyberspace considering Rome II Regulation.

To determine diagnostic performance of simple measurements on diffusion-weighted MR imaging (DWI) for assessment of complete tumour response (CR) after neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC) by signal intensity (SI) and apparent diffusion coefficient (ADC) measurements. Sixty-five patients with LARC who underwent neoadjuvant CRT and subsequent surgery were included. Patients underwent pre-CRT and post-CRT 3.0 T MRI. Regions of interest of the highest brightness SI were included in the tumour volume on post-CRT DWI to calculate the SI{sub lesion}, rSI, ADC{sub lesion} and rADC; diagnostic performance was compared by using the receiver operating characteristic (ROC) curves. In order to validate the accuracy and reproducibility of the current strategy, the same procedure was reproduced in 80 patients with LARC at 1.5 T MRI. Areas under the ROC curve for identification of a CR, based on SI{sub lesion}, rSI, ADC{sub lesion}, and rADC, respectively, were 0.86, 0.94, 0.66, and 0.71 at 3.0 T MRI, and 0.92, 0.91, 0.64, and 0.61 at 1.5 T MRI. Post-CRT DWI SI{sub lesion} and rSI provided high diagnostic performance in assessing CR and were significantly more accurate than ADC{sub lesion}, and rADC at 3.0 T MRI and 1.5 T MRI. (orig.)

Technology transfer: federal legislation that helps businesses and universities

Oaks, Bill G.

1992-05-01

In 1980, Congress enacted the Stevenson-Wydler Technology Innovation Act to encourage federal laboratories to `spin off' their technology to industry, universities, and state and local governments. The law reflected Congressional concern for the economic well-being of the nation and the need for the United States to maintain its technological superiority. Almost half the nation's research is conducted in federal laboratories. Other legislation, the Small Business Innovation Development Act of 1982 and the National Cooperative Research Act of 1984, was followed by the Technology Transfer Act of 1986 that strengthened and consolidated policy concerning the technology transfer responsibilities of the federal labs. The law allows the labs to directly license their patents and permits the issuance of exclusive licenses. It allows the labs to enter into cooperative research and development agreements with industry, universities, and state and local governments. It institutionalized the Federal Laboratory consortium which, to that point in time, had been a formal but largely unrecognized body. Under the provisions of the law, the United States Air Force Rome Laboratory located in Rome, New York, as the Air Force lead laboratory in photonics research entered into an agreement with the Governor of the State of New York to collaborate in photonics research and development. Subsequent to that agreement, the state established the not-for-profit New York State Photonics Development Corporation in Rome to facilitate business access to Rome Laboratory's photonics research facilities and technologies. Rome Laboratory's photonics research and development program is described in this paper. The Technology Transfer Act of 1986 is summarized, and the roles and missions of the New York State Photonics Development Corporation is explained.

Objective: To explore the value of diffusion weighted imaging (DWI) in differentiating intracranial tuberculomas from high-grade astrocytomas and metastases. Methods: The conventional MR imaging and DWI were performed in 50 eases (14 cases with intracranial tuberculomas, 15 cases with high- grade astrocytomas, and 21 cases with metastases) before treatment or operation. The mean apparent diffusion coefficient (ADC) values and relative apparent diffusion coefficient (rADC) values were calculated from the mass as well as from the peripheral edema regions of intracranial lesions. Results: The mean ADC values and rADC values were (1.2±0.2) x 10 -3 mm 2 ·s -1 and 1.6±0.3 in the mass of intracranial tuberculomas respectively; (0.8±0.1) x 10 -3 mm 2 ·s -1 and 1.1±0.1 in the parenehyma of high-grade astrocytomas; (0.8±0.1) x 10 -3 mm 2 ·s -1 and 1.0±0.2 in the parenchyma of metastases. There was significant difference of the mean ADC values (F=33.57, P -3 mm 2 ·s -1 and 2.5±0.2 in the peripheral edema regions of intracranial tuberculomas respectively; (1.4±0.2) x 10 -3 mm 2 ·s -1 and 1.8±0.3 in the peripheral edema regions of high-grade astrocytomas; and (1.9±0.2) x 10 -3 mm 2 ·s -1 and 2.3±0.5 in the peripheral edema regions of metastases. There was also significant difference in the mean ADC values (F23.17, P<0.01) or rADC values (F=5.94, P<0.01) among the peripheral edema regions of the three groups. Conclusion: The ADC values and rADC values are quite effective in differentiating intracranial tuberculoma from high-grade astrocytoma and metastasis. (authors)

The US Air Force Air Combat Command (ACC) has tasked the US Department of Energy (DOE) Federal Energy Management Program (FEMP) to identify, evaluate, and assist in acquiring all cost-effective energy projects at Griffiss Air Force Base (AFB). FEMP, with support from the Pacific Northwest Laboratory (PNL), is designing this model program for federal customers served by the Niagara Mohawk Power Company. The program with Griffiss AFB will (1) identify and evaluate all cost-effective electric energy projects; (2) develop a schedule for project acquisition considering project type, size, timing, capital requirements, as well as energy and dollar savings; and (3) secure 100% of the financing required to implement electric energy efficiency projects from Niagara Mohawk and have them procure the necessary contractors to perform detailed audits and install the technologies. This report provides the results of the electric energy resource opportunity (ERO) assessments performed by PNL at one of Niagara Mohawk`s primary federal facilities, the ACC Griffiss AFB facility located near Rome, New York. The results of the analyses of EROs are presented in seven common energy end-use categories. A narrative description of each ERO provides information on the initial cost, energy and dollar savings; impacts on operations and maintenance (O&M); and, when applicable, a discussion of energy supply and demand, energy security, and environmental issues. The evaluation methodology and technical and cost assumptions are also described for each ERO. Summary tables present the operational performance of energy end-use equipment before and after the implementation of each ERO and the results of the life-cycle cost analysis indicating the net present value (NPV) and savings-to-investment ratio (SIR) of each ERO.

Le jeu de l’intertextualité dans Rome sauvée ou Catilina de Voltaire : Les enjeux de transmotivation et de transvalorisation // The intertextuality in the Voltaire’s tragedy Rome sauvée ou Catilina: The issue of transmotivation and revaluation

Directory of Open Access Journals (Sweden)

Marek Očenáš

2015-12-01

Full Text Available The article deals with intertextual relationships of the xviiith century tragedy : these relationships are particularly rich, because the contemporary dramatist partly seeks a theme in the works of ancient authors, and he partly uses contemporary drama procedures and he separates himself from dramas/plays with the same subject. The characteristic feature of processing of the play of the same idea is transmotivation and revaluation, which functioning is supported by author’s analysis of Voltaire’s tragedy “Rome sauvée ou Catilina”, taking into account Voltaire’s rivals plays — Catiline by Ben-Johnson and especially Catilina by Crébillon. Just the confrontation of these plays allows defining principles of Voltaire’s dramaturgy : the structural role of love in motivating acts and the moral elevation of the hero, who has to be an example.

Saverio Miccoli

2015-11-01

Full Text Available Many large projects held over the last few decades in Europe have been based on the enhancement of community goods as a strategy to put in place sustainable urban regeneration. The inclusive nature of these goods and the social importance of the related decision-making processes suggests the need to involve the relevant community and to take into account its intentions and wishes regarding planning and organization. Therefore, before even starting to plan possible interventions, it is crucial to know what the members of the community think about the good in terms of social appreciation, in order to achieve socially sustainable choices. This paper offers a method to measure the social appreciation of community goods and describes the following: (a deliberative esteem value technology to measure the social appreciation based on a combination between stated preference techniques and deliberative methods; (b the criterion and methodology of the valuation technique proposed; and (c an experimental application of the valuation technique pertinent to the specific case of the East Elevated Expressway of Rome.

2009-02-01

A multitemporal analysis on a humid area in Rome's archaeological site is presented; the floristic data are used as bioindicators for main environmental changes over the last 50 years. By comparing the structural, biogeographical and ecological features of today's florula with the ones of a 1955 survey, and by assessing the new, the rare and the locally disappeared species, it was possible to define and analyse the main floristic changes and their ecological meaning for this site. Our results show that the floristic richness of the area did not differ significantly from 1955. However, the species composition has changed considerably: over 40% of the species have disappeared. More than half of these were rare and typical of humid environments. Approximately the same number of species has appeared but these are mainly ruderal and widespread entities, with the overall result being a progressive and general vulgarization of the local flora. Finally, we analyse the main reasons, linked for the most part to human activities, which led to the reported floristic changes.

The Case of Capogrossi in Rome: Collecting Data with Different Technologies on a Contemporary Mural Painting

Mezzadri, P.; Russo, J.

2017-05-01

This paper focuses on the presentation of a part of the main thematic data documenting the pathologies and the degradation problems of a contemporary mural painting, which was designed and carried out by the italian artist Giuseppe Capogrossi in 1954. This forgotten masterpiece is developed on the ceilings of the main double stairscase at the entrance of the Airone, an ex-cinema-theatre in Rome (Italy). In time, the original project was completely damaged and now the Airone cinema is abandoned since 1999; the decoration, strictly connected to the function of the original project, has been completely covered by synthetic coatings. The documentation of the observed pathologies and the original materials of the lower ceiling takes place during a restoration project in 2015-2016 and was accomplished by utilizing different technologies in order to facilitate the collecting of the main data within several graphic thematic tables. The challenge of this documentation was to create a contact point, and perhaps also a contamination, between the practices of CAD graphic documentation, restoration and GIS technology.

The CMS Electromagnetic Calorimeter: Results on Crystal Measurements, Quality Control and Data Management in the Rome Regional Center

Costantini, S

2004-01-01

The barrel of the CMS electromagnetic calorimeter is currently under construction and will contain 61200 PbWO4 crystals. Half of them are being fully characterized for dimensions, optical properties and light yield in the INFN-ENEA Regional Center near Rome. We describe the setup of an automatic quality control system for the crystal measurements and the present results on their qualification, as well as the REDACLE project, which has been developed to control and ease the production process. As it will not be possible to precalibrate the whole calorimeter,the crystal measurements and quality checks performed at the Regional Center will be crucial to provide a basis for fast in-situ calibration with particles. REDACLE is at the same time a fast database and a data management system, where the database and the workflow structures are decoupled, in order to obtain the best flexibility.

Air pollution is associated with several adverse health outcomes in children, such as respiratory illnesses and cognitive development impairment. There are suggestions of an effect of traffic-related air pollution on the occurrence of childhood obesity, but the results are not consistent. The aim of the study is to analyse whether air pollution and vehicular traffic exposure, during the first four years of life, influence obesity- related measures among 4 and 8-year-old children from a prospective birth cohort in Rome. A cohort of newborns, enrolled in 2003-2004 within the GASPII project, was followed at 4 and 8 years of age with parental interviews and clinical examinations. Air pollution was assessed at residential address using Land Use Regression models (for NO 2 , NOx, PM 10 , PM 2.5 , PMcoarse, PM2.5 absorbance and one traffic variable (Total traffic load of all roads in a 100m buffer)). The outcomes under study were body mass index (BMI Z-scores according to WHO recommendations, considered both categorical and continuous) measured at 4 and 8 years, and, waist circumference, waist-to-hip ratio, total and HDL cholesterol measured at 8 years. The associations were evaluated through both cross-sectional and longitudinal approaches, using logistic regression models, Generalized Estimating Equation models (GEE) and linear regression models, as appropriate. Moreover, Inverse Probability Weighting (IPW) methodology was used to account for selection bias at enrolment and at follow-up. A total of 719 infants were enrolled and 581 (80.8%) and 499 (69.4%) were followed at 4 and 8 years, respectively. The prevalence of overweight/obesity was 9.3% and 36.9% at 4 and 8 years. No evidence of an association was found between vehicular traffic and being overweight/obese. Similarly, there was no evidence of an association between exposure to air pollutants and all other ponderal excess parameters. The study shows no association between exposure to vehicular traffic and

this study aims at presenting the results from the Italian EpiaAir2 Project on the short-term effects of air pollution on adult population (35+ years old) in 25 Italian cities. the short-term effects of air pollution on resident people died in their city were analysed adopting the time series approach. The association between increases in 10µg/m(3) in PM10, PM2.5, NO2 and O3 air concentration and natural, cardiac, cerebrovascular and respiratory mortality was studied. City-specific Poisson models were fitted to estimate the association of daily concentrations of pollutants with daily counts of deaths. The analysis took into account temporal and meteorological factors to control for potential confounding effect. Pooled estimates have been derived from random effects meta-analysis, evaluating the presence of heterogeneity in the city specific results. it was analysed 422,723 deaths in the 25 cities of the project among people aged 35 years or more, resident in each city during the period 2006-2010. daily counts of natural, cardiac, cerebrovascular, and respiratory mortality, obtained from the registries of each city. Demographic information were obtained by record linkage procedure with the civil registry of each city. mean number of deaths for natural causes ranged from 513 in Rovigo to 20,959 in Rome. About 25% of deaths are due to cardiac diseases, 10% to cerebrovascular diseases, and 7% to respiratory diseases. It was found an immediate effect of PM10 on natural mortality (0.51%; 95%CI 0.16-0.86; lag 0-1). More relevant and prolonged effects (lag 0-5) have been found for PM2.5 (0.78%; 95%CI 0.12-1.46) and NO2 (1.10%; 95%CI 0.63-1.58). Increases in cardiac mortality are associated with PM10 (0.93%; 95%CI 0.16-1.70) and PM2.5 (1.25%; 95%CI 0.17-2.34), while for respiratory mortality exposure to NO2 has an important role (1.67%; 95%CI 0.23-3.13; lag 2-5), as well as PM10 (1.41%; 95%CI - 0.23;+3.08). Results are strongly homogeneous among cities, except for

Analysis of the Seismic Site Effects along the Ancient Via Laurentina (Rome

Full Text Available This paper presents an evaluation of the Local Seismic Response (LSR along the route of the ancient Roman road Via Laurentina, which has been exposed in several areas of southwest Rome over the last decade during the construction of new buildings and infrastructures. It is an example of LSR analysis applied to ancient and archaeological sites located in alluvial valleys with some methodological inferences for the design of infrastructure and urban planning. Since the ancient road does not cross the alluvial valley (namely the Fosso di Vallerano Valley normal to its sides, it was not possible to directly perform 2D numerical modelling to evaluate the LSR along the road route. Therefore, outputs of 2D numerical models obtained along three cross sections that were normal oriented respect to the valley were projected along the route of the Via Laurentina within a reliable buffer attributed according to an available high-resolution geological model of the local subsoil. The modelled amplification functions consider physical effects due to both the 2D shape of the valley and the heterogeneities of the alluvial deposits. The 1D and 2D amplification functions were compared to output that non-negligible effects are related to the narrow shape of the fluvial valley and the lateral contacts between the lithotecnical units composing the alluvial fill. The here experienced methodology is suitable for applications to the numerical modelling of seismic response in case of linear infrastructures (i.e., roads, bridges, railways that do not cross the natural system along physically characteristic directions (i.e. longitudinally or transversally.

[Aspects of senile dementia in ancient Rome: literary fiction and factual reality].

Science.gov (United States)

Moog, Ferdinand Peter; Schäfer, Daniel

2007-01-01

Old people and their pecularities have been the object of writers since the beginning of Western literature. The aim of this study is to verify the social and juridical significance of senile dementia in ancient Rome. Among the few relevant sources the 10th satire of Juvenal attracts attention. It describes a demented patient who revises his succession in favour of a lady with bad reputation. Logically, we wonder whether such dispositions were possible and after all legally binding. Or did Juvenal exaggerate? A look at the Roman legislation shows: Since the Twelve Tablet Law there were instruments to control or to help demented people. This meant care in the sense of the today's curatorship or guardianship. These measures were supposed to prevent extravagancy or doing business and legal acts like marriages or last wills in the state of diminished responsibility. Nevertheless, it must be assumed that there was a considerable discrepancy between juridical theory and daily practice, because the position of the "pater familias" was virtually untouchable, the individual freedom of the full citizen was firmly underlined and the Roman civil law allowed only little executive interferences. Juvenal's bizarre example should not only be taken as good literary fiction. It might reflect the sad, but nevertheless probable reality of the people directly concerned. Apart from that it has to be said that senile dementia played only a minor role in Roman legislation. Mainly because there were considerably less very old people--and in particular people with senile dementia--than today.

2015-11-01

The 28th International Conference on Antiviral Research (ICAR) was held in Rome, Italy from May 11 to 15, 2015. This article summarizes the principal invited lectures. Phillip Furman, the Elion award recipient, described the research leading to sofosbuvir. Dennis Liotta, who received the Holý award, described how an investigation into HIV entry inhibitors led to a new therapy for cancer patients. Erica Ollmann Saphire, winner of the Prusoff Young Investigator award, explored the world of viral proteins and how they remodel to perform different essential roles in viral replication. The keynote addresses, by Raffaele De Francesco and Michael Manns, reported on the remarkable progress made in the therapy of chronic HCV infections. A third keynote address, by Armand Sprecher, related the difficulties and successes of Médicins Sans Frontières in West Africa ravaged by the Ebola outbreak. There were three mini-symposia on RNA Viruses, Antiviral Chemistry and Emerging Viruses. There was a good collection of talks on RNA viruses (norovirus, rabies, dengue, HEV, HCV, and RSV). A highlight of the chemistry was the preparation of prodrugs for nucleotide triphosphates as this opens a door to new options. The third mini-symposium emphasized how research work in the antiviral area is continuing to expand and needs to do so with a sense of urgency. Although this meeting report covers only a few of the presentations, it aims to illustrate the great diversity of topics discussed at ICAR, bringing together knowledge and expertise from the whole spectrum of antiviral research.

Full Text Available European eel and chub samples were analyzed to determine the levels of non-dioxin-like polychlorobiphenyls (NDL-PCBs, polychlorodibenzodioxins (PCDDs and polychlorodibenzofurans (PCDFs, dioxin-like PCBs (DL-PCBs, and brominated polybromodiphenyl ethers (PBDEs in order to evaluate the extent of contamination of the river Tiber along the urban tract through the city of Rome (Italy. All samples presented detectable levels of the chemicals analyzed, and exhibited species-specific differences in terms of congener composition and total concentrations. On average the European eel presented the highest values. In this species the dioxin-like compound sums (WHO-TEQs exceeded the pertinent maximum levels (MLs. Non-ortho PCBs constituted approximately 80% of WHO-TEQ toxicological potential whereas NDL-PCB and PBDE concentrations appeared to match values determined in other polluted aquatic ecosystems where non-point contamination sources were present. The contamination patterns determined in fish tissues seemed to reflect the impact of generic contamination source(s.

The development of close-range photogrammetry has produced a lot of new possibility to study cultural heritage. 3D data acquired with conventional and low cost cameras can be used to document, investigate the full appearance, materials and conservation status, to help the restoration process and identify intervention priorities. At the same time, with 3D survey a lot of three-dimensional data are collected and analyzed by researchers, but there are a very few possibility of 3D output. The augmented reality is one of this possible output with a very low cost technology but a very interesting result. Using simple mobile technology (for iPad and Android Tablets) and shareware software (in the case presented "Augment") it is possible to share and visualize a large number of 3D models with your own device. The case study presented is a part of an architecture graduate thesis, made in Rome at Department of Architecture of Roma Tre University. We have developed a photogrammetric survey to study the Aurelian Wall at Castra Praetoria in Rome. The surveys of 8000 square meters of surface have allowed to identify stratigraphy and construction phases of a complex portion of Aurelian Wall, specially about the Northern door of Castra. During this study, the data coming out of 3D survey (photogrammetric and topographic), are stored and used to create a reverse 3D model, or virtual reconstruction, of the Northern door of Castra. This virtual reconstruction shows the door in the Tiberian period, nowadays it's totally hidden by a curtain wall but, little and significative architectural details allow to know its original feature. The 3D model of the ancient walls has been mapped with the exact type of bricks and mortar, oriented and scaled according to the existing one to use augmented reality. Finally, two kind of application have been developed, one on site, were you can see superimposed the virtual reconstruction on the existing walls using the image recognition. On the other hand

The ASL Rome "C" community-based psychiatric service. Verona Service Satisfaction Scale-54, a multidimensional instrument which measure satisfaction with community-based psychiatric service. Main results (301 scales for patients, 163 scales for relatives), pointed out for patients a higher satisfaction for the technical and interpersonal skills of psychiatrists and psychologists (score of specific items > 4). Lowest scores of satisfaction were towards the appearance, comfort level and physical layout of the facility (score 2.95) and towards the response of the service to emergencies during the night, weekend and Bank Holidays (score 2.87). Relatives were not particularly keen for the item regarding help to find open employment (score 2.76). Furthermore patients and their relatives gave a negative evaluation of the publicity and information offered by Mental Health Services. Dimension's analysis reaches the same conclusions deduced items's average score. The result of this study emphasizes the patients higher degree of satisfaction than the relatives. The above results point out three aspects to be improved by the Mental Health Service in order to satisfy the demands of the patients and relatives: 1. appearance, comfort level and physical layout of the facility, 2. publicity and information, 3. social activities and social skills.

New concept of functional anorectal disorders. In relation to newly published ROME III

International Nuclear Information System (INIS)

Takano, Masahiro

2007-01-01

In newly published Rome III, Functional anorectal disorders are divided into 7 disorders. F1 Functional fecal incontinence is divided into staining, soiling, seepage and leakage in the degree and urge and passive incontinences in the dynamics, of which the former is dysfunction of the rectum and the latter of the anus. For the treatment, the most effective is biofeedback therapy (BF). F2 Functional anorectal pain is divided into F2a Chronic proctalgia, F2a1 Levator ani syndrome, F2a2 Unspecified functional anorectal pain and F2b Proctalgia fugax. F2a1 Levator ani syndrome is defined as a pain caused by traction of the levator ani, but in my experience, only 4 (3.5%) among 116 cases accorded to the criteria making us dubious of the definition. As for F2b Proctalgia fugax, the cause has not yet been found. In these two F2a, various treatments are tried without significant effectiveness due perhaps to the unknown pathogenesis which I assume to be the neuralgia of pudendal nerve. F3 Functional defecation disorders consist of F3a Dyssynergic defecation and F3b Inadequate defecatory propulsion of which, the former is caused by paradoxical contraction or inadequate relaxation of the pelvic floor muscles and the latter caused by inadequate propulsive force in defecation. Their treatments are BF and defecatory enforcement. (author)

Inference in media space. The case of IBM Software Executive Briefing Center - Rome

Toni Marino

2014-11-01

Full Text Available In our paper we apply Peirce's model of Arguments (Statistical Deduction, Probabilistic Deduction, Induction and Abduction to a communication process where negotiating sense and meanings is emphasized. We selected a communication space where everything is planned as a medium of sense (video terminals, screens, lights, etc. namely the IBM Software Executive Briefing Center in Italy, a workplace used to exchange views, negotiate or transact. It is based in Rome in the same building as the International Development Laboratory of the IBM Software Group. The Software Center is the place where IBM welcomes its potential customers and has the opportunity to show them its technology and offer solutions. This paper focuses on "media space" in the Center which is structured by the seller according to his/her idea of the buyer's interpretive process. This paper analyzes the roles of visual codes in the allocation of functions. It also looks into the relation between the symbolism of the company with its marketing, past history and media space in order to define the buyer's typology of inference (deduction, induction or abduction in relation to the communication strategy of the media space design. The research is conducted directly in the field by interviewing the Manager of the IBM Center as well as asking people who use it to fill in an anonymous questionnaire, which analyses both the media space and the plan of the building.

Stress at work: development of the Stress Perception Questionnaire of Rome (SPQR), an ad hoc questionnaire for multidimensional assessment of work related stress.

Science.gov (United States)

Cinti, M E; Cannavò, M; Fioravanti, M

2017-01-01

Stress is an emotional condition, mostly experienced as negative, initially identified and defined by Selye in the mid-thirties of the last Century. Since the first definition, stress concerns the adaptation pro- cess mostly related to environmental changes. An application of stress focuses on the evaluation of its interference on work conditions, and the scientific evidence on work related stress is very ample and rich. We are proposing a new ad hoc questionnaire for the multidimensional assessment of work related stress, called Stress Perception Question- naire of Rome (SPQR) composed of 50 items. The development of this questionnaire is based on a multi-step process: a) Identification of all the relevant topics to work related stress and areas in the scientific evidence and their transformation on specific contents of 60 tentative items; b) Exploratory factor analysis aimed to identify the best items (50) which could guarantee the maximum convergence on single scales (8), and the minimum redundancy between scales; c) Validation of the 8 scales' structure by a confirmatory factor analysis (fully achieved); d) Factor analysis for a second level factor resulting in a single factor identified as the questionnaire total score (Stress Score); d) Reliability analysis of the questionnaire total score and the single scale scores (at optimum level); e) Validation by external criteria of work related stress identified in the presence of personal violence episodes experienced by a group of health workers with different professional profiles and from two different hospitals in Rome. Our results show that the SPQR is a useful and sensitive tool for assessing the presence of emotional stress related problems identifiable in a work environment. The advantage of this questionnaire is that it allows for a multidimensional description of the different components of this problematic area besides its ability to quantify the overall stress level of those who have been administered

Liminal cosmopolitanisms: Identity strategies and categorization of culture and class in multi-ethnic squats in Rome

Directory of Open Access Journals (Sweden)

Piero Vereni

2016-08-01

Full Text Available In the last twenty years, the squatting movement in Rome has witnessed a steady increase of foreign participants as regular members but a scarce presence among the leadership. Moreover, the incidence of immigrants among squatters is typically not marked in the public self-representation of the movement yet overemphasized and disputed by mainstream media. The essay attempts an interpretation of this peculiar distribution of foreign immigrants among squatters. On the one side, their being foreigners within Italian welfare puts them at risk of higher exclusion; on the other, political leaders in the squats may see the foreigners (as bearers of a shared class condition as a suitable pool for the wider political aim of squatting, namely the implementation of an alternative urban lifestyle. Furthermore, foreigners may take part into squats just as a self-attained form of social emancipation, since the act of squatting may equal an otherwise inaccessible house possession. Within these apparently contradictory aims, multi-ethnic squats turn into cosmopolitan spaces of identities that accept transcending their specificities to pour into a common kiln of class identity, between revolutionary proletariat and pity bourgeoisie seeking full social integration.

Sixty-seven transvestite prostitutes from Latin America (49 from Brazil and 18 from Colombia) who attended an HIV unit located in the inner city of Rome between January 1991 and June 1992 were studied for syphilis markers by means of both the Treponema pallidum haemoagglutination test (TPHA) and a solid phase haemadsorption test for detection of specific IgM (SPHA-IgM) which are typically present in recent infections. All participants reported more than 500 sexual partners in the past year, and 67.1% of them more than 1500 partners (between 5 and 10 partners per working day). The overall prevalence of anti-HIV antibodies in this population was 65.7%. The prevalence of positive TPHA tests in the population studied was 73.1%, while that of positive SPHA-IgM tests was 10.4%. The prevalence of positive TPHA and SPHA-IgM tests was higher among Columbians than among Brazilians (83.3% vs 69.4% and 22.2% vs 6.1%, respectively) and also showed a positive correlation with the duration of their permanence in Italy. The TPHA and SPHA-IgM positivities were significantly higher among subjects older than 29 years. Positive TPHA was also significantly higher in subjects who reported a history of heroin and/or cocaine abuse while positive SPHA-IgM was higher in subjects who did not use condoms or reported irregular use of them than in subjects who regularly used condoms. No overall correlation was evident between TPHA positivity and anti-HIV positivity, while SPHA-IgM positivity was found to be higher among anti-HIV-negative subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to investigate MRI-derived diffusion weighted imaging (DWI) and arterial spin labeling (ASL) perfusion imaging in comparison with {sup 18}F-dihydroxyphenylalanine (DOPA) PET with respect to diagnostic performance in tumor grading and outcome prediction in pediatric patients with diffuse astrocytic tumors (DAT). We retrospectively analyzed 26 children with histologically proven treatment naive low and high grade DAT who underwent ASL and DWI performed within 2 weeks of {sup 18}F-DOPA PET. Relative ASL-derived cerebral blood flow max (rCBF max) and DWI-derived minimum apparent diffusion coefficient (rADC min) were compared with {sup 18}F-DOPA uptake tumor/normal tissue (T/N) and tumor/striatum (T/S) ratios, and correlated with World Health Organization (WHO) tumor grade and progression-free survival (PFS). Statistics included Pearson's chi-square and Mann-Whitney U tests, Spearman's rank correlation, receiver operating characteristic (ROC) analysis, discriminant function analysis (DFA), Kaplan-Meier survival curve, and Cox analysis. A significant correlation was demonstrated between rCBF max, rADC min, and {sup 18}F-DOPA PET data (p < 0.001). Significant differences in terms of rCBF max, rADC min, and {sup 18}F-DOPA uptake were found between low- and high-grade DAT (p ≤ 0.001). ROC analysis and DFA demonstrated that T/S and T/N values were the best parameters for predicting tumor progression (AUC 0.93, p < 0.001). On univariate analysis, all diagnostic tools correlated with PFS (p ≤ 0.001); however, on multivariate analysis, only {sup 18}F-DOPA uptake remained significantly associated with outcome (p ≤ 0.03), while a trend emerged for rCBF max (p = 0.09) and rADC min (p = 0.08). The combination of MRI and PET data increased the predictive power for prognosticating tumor progression (AUC 0.97, p < 0.001). DWI, ASL and {sup 18}F-DOPA PET provide useful complementary information for pediatric DAT grading. {sup 18}F-DOPA uptake

Led by the Italian Institute for Environmental Protection and Research, in collaboration with NERC British Geological Survey, Geological and Mining Institute of Spain, University of Milano-Bicocca and Cyprus University of Technology, the PROTHEGO project, co-funded in the framework of JPI on Cultural Heritage EU program (2015-2018), brings an innovative contribution towards the analysis of geo-hazards in areas of cultural heritage in Europe. The project apply InSAR techniques to monitor monuments and sites that are potentially unstable due to natural geo-hazard. After the remote sensing investigation, detailed geological interpretation, hazard analysis, local-scale monitoring, advanced modeling and field surveying for some case studies is implemented. The selected case studies are: the Alhambra in Granada (ES); the Choirokoitia village (CY); the Derwent Valley Mills (UK); the Pompei archaeological site and Historical centre of Rome (IT). In this work, in particular, we will focus on ground deformation measurements (obtained by satellite SAR Interferometry) and on their interpretation with respect to the ancient Rome City Walls. The research activities carried out jointly with the Superintendence's technicians, foresee the implementation of a dedicated web GIS platform as a final repository for data storage and spatial data elaboration. The entire circuit of the ancient city walls (both Mura Aureliane and Mura Gianicolensi), was digitalized and georeferenced. All the elements (towers, gates and wall segments) were drawn and collected in order to produce a map of elements at risk. A detailed historical analysis (during the last twenty years) of the ground and structural deformations were performed. A specific data sheet of ruptures was created and fulfilled in order to produce a geographic inventory of past damage. This data sheet contains the following attributes: triggering data; typology of damage; dimension, triggering mechanism; presence of restoration works

This work focuses on preliminary results achieved by means of a research project carried out by ISPRA in collaboration with Soprintendenza Capitolina (the Cultural Heritage Capitoline Superintendence), aimed at defining an interpretative model of natural and anthropic evolution of the Pincio Hill (Rome, Italy) during the last 2,500 years. The study area is located in the NE sector of the city of Rome and includes the Pincio hill Cultural Heritage site and the surrounding area of the Tiber River flood plain. The Pincio Hill is a very interesting case of interplay among: i) natural landscape setting; ii) historical urban transformations; iii) human activity and recurrence of natural hazard events impacting heavily on the territory since ancient times. During the last decades, designs of new areas to be allocated for underground parking jointly with new archaeological excavations surveys have allowed the acquisition of a large amount of new data. The study has been carried out through a new reinterpretation of recently drilled boreholes stratigraphic logs and the conspicuous related archaeological literature. The main outcome of the research activities are summarized as below. Concerning the top of the hill, latest archaeological excavations brought to the light traces of ancient structures and settlements dating from the Archaic period until the fourth century AD, highlighting the facto the character of strong agricultural and landscape appeal that have involved the western sector of the Pincio hill since the ancient times, without evidence of relevant alterations of the original landscape. In the slope sector, the information coming from geotechnical survey allowed the reconstruction of isochronous surfaces inside of landfills, divided according to their age. The profile of the slope below the landfill from the Roman period seems very steep and irregular, in strong contrast to the medieval one and the current one, characterized by multiple succession of terraces.

Abdominal pain is common in patients with functional bowel disorders (FBDs). The aim of this study was to characterize the predominant sites of abdominal pain associated with FBD subtypes, as defined by the Rome III criteria. A total of 584 consecutive patients attending FBD consultations in a tertiary center participated in the study. Stool form, abdominal pain location (nine abdominal segments), and pain intensity (10-point Likert scale) during the previous week were recorded. Logistic regression analysis was used to characterize the association of abdominal pain sites with specific FBD subtypes. FBDs were associated with predominant pain sites. Irritable bowel syndrome (IBS) with constipation was associated with pain in the left flank and patients were less likely to report pain in the right hypochondrium. Patients with functional constipation reported pain in the right hypochondrium and were less likely to report pain in the left flank and left iliac site. IBS with alternating constipation and diarrhea was associated with pain in the right flank, and unsubtyped IBS with pain in the hypogastrium Patients with functional abdominal pain syndrome reported the lower right flank as predominant pain site. Patients with unspecified FBDs were least likely to report pain in the hypogastrium. Patients with functional diarrhea, IBS with diarrhea, or functional bloating did not report specific pain sites. The results from this study provide the basis for developing new criteria allowing for the identification of homogeneous groups of patients with non-diarrheic FBDs based on characteristic sites of pain. © 2013 John Wiley & Sons Ltd.

The aims of this study were to observe magnetic resonance imaging (MRI) features and the frequency of hemorrhagic transformation (HT) in patients with acute cerebral infarction and to identify the risk factors of HT. We first performed multimodal MRI (anatomical, diffusion weighted, and susceptibility weighted) scans on 87 patients with acute cerebral infarction within 24 hours after symptom onset and documented the image findings. We then performed follow-up examinations 3 days to 2 weeks after the onset or whenever the conditions of the patients worsened within 3 days. We utilized univariate statistics to identify the correlations between HT and image features and used multivariate logistical regression to correct for confounding factors to determine relevant independent image features of HT. HT was observed in 17 out of total 87 patients (19.5 %). The infarct size (p = 0.021), cerebral microbleeds (CMBs) (p = 0.004), relative apparent diffusion (rADC) (p = 0.023), and venous anomalies (p = 0.000) were significantly related with HT in the univariate statistics. Multivariate analysis demonstrated that CMBs (odd ratio (OR) = 0.082; 95 % confidence interval (CI) = 0.011-0.597; p = 0.014), rADC (OR = 0.000; 95 % CI = 0.000-0.692; p = 0.041), and venous anomalies (OR = 0.066; 95 % CI = 0.011-0.403; p = 0.003) were independent risk factors for HT. The frequency of HT is 19.5 % in this study. CMBs, rADC, and venous anomalies are independent risk factors for HT of acute cerebral infarction. (orig.)

Multivariate analysis demonstrated that CMBs (odd ratio (OR) = 0.082; 95 % confidence interval (CI) = 0.011-0.597; p = 0.014), rADC (OR = 0.000; 95 % CI = 0.000-0.692; p = 0.041), and venous anomalies (OR = 0.066; 95 % CI = 0.011-0.403; p = 0.003) were independent risk factors for HT. The frequency of HT is 19.5 % in this study. CMBs, rADC, and venous anomalies are independent risk factors for HT of acute cerebral infarction. (orig.)

To investigate the pathophysiology of functional heartburn (FH) in Japanese patients. A total of 111 patients with proton pump inhibitor (PPI)-refractory non-erosive gastroesophageal reflux disease underwent intraesophageal pressure testing and 24-h multichannel intraluminal impedance-pH (24MII-pH) testing. The patients also completed several questionnaires while they were receiving the PPI treatment, including the questionnaire for the diagnosis of reflux disease (QUEST), the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG), the gastrointestinal symptoms rating scale (GSRS), SF-36, and the Cornell Medical Index (CMI). The subjects were classified into FH and endoscopy-negative reflux disease (ENRD) groups based on the Rome III criteria. Thirty-three patients with esophageal motility disorder were excluded from this study, while 22 patients with abnormal esophageal acid exposure time (pH-POS) and 34 with hypersensitive esophagus (HE) were included in the ENRD group. The FH group included 22 patients with no reflux involvement. Sex, age, and body mass index did not differ significantly between the groups. The mean SF-36 values were < 50 (normal) for all scales in these groups, with no significant differences. The GSRS scores in these groups were not different and showed overlap with other gastrointestinal symptoms. The QUEST and the FSSG scores did not differ significantly between the groups. Neuroticism was diagnosed using the CMI questionnaire in 17 of the 78 included subjects within the pH-POS (n = 4), HE (n = 8), and FH (n = 5) groups, with no significant differences. Clinical characteristics of the FH and PPI-refractory ENRD groups were similar. Therefore, esophageal function should be examined via manometry and 24MII-pH testing to differentiate between them.

Giuseppe Campani (1635-1715) was a polymath in Rome, Italy, during the Scientific Revolution in the XVIIth century. In particular, he forged the screw barrel microscope and was manufacturing his own lenses for microscopes and telescopes. He mastered the art of lens grinding. Those lenses have been analyzed with modern methods and turned out to be of extremely good quality, shining light on the fact that Giuseppe Campani mastered the theories of optics. Moreover, in a letter that Giuseppe Campani sent to Pope Innocent XI, he clearly described the use of a microscope for the examination of wounds of legs. This letter dates back to 15 August 1686 and is the first evidence of the use of microscopes to analyze wounds, sores, and anatomic specimens in medical and surgical settings. MG Yasargil previously showed the lithography accompanying this letter and was the first to recognize its great importance. We accessed this original letter in the Vatican Library, and for the first time we have translated it from Latin to English in order to unveil its significance in the context of the Scientific Revolution and the history of medicine and surgery.

1994-06-01

Full Text Available A methodology is used which combines stochastic generation of random series with a finite-difference technique to estimate the expected horizontal ground motion for the city of Rome as induced by a large earthquake in the Central Apennines. In this approach, source properties and long-path propagation are modelled through observed spectra of ground motion in the region, while the effects of the near-surface geology in the city are simulated by means of a finite-difference technique applied to 2-D models including elastic and anelastic properties of geologic materials and topographic variations. The parameters commonly used for earthquake engineering purposes are estimated from the simulated time histories of horizontal ground motion. We focus our attention on peak ground acceleration and velocity, and on the integral of the squared acceleration and velocity (that are proportional to the Arias intensity and seismic energy flux, respectively. Response spectra are analyzed as well. Parameter variations along 2-D profiles visualize the effects of the small-scale geological heterogeneities and topography irregularities on ground motion in the case of a strong earthquake. Interestingly, the largest amplification of peak ground acceleration and Arias intensity does not necessarily occur at the same sites where peak ground velocity and flux of seismic energy reach their highest values, depending on the frequency band of amplification. A magnitude 7 earthquake at a distance of 100 km results in peak ground accelerations ranging from 30 to 70 gals while peak ground velocities are estimated to vary from 5 to 7 cm/s; moreover, simulated time histories of horizontal ground motion yield amplitudes of 5% damped pseudovelocity response spectra as large as 15-20 cm/s for frequencies from 1to 3 Hz. In this frequency band, the mean value is 7 cm/s for firm sites and ranges from 10 to 13 cm/s for soil sites. All these results are in good agreement with predictions

Early life exposure to air pollution has been linked with cognitive impairment in children, but the results have not been conclusive. We analyzed the association between traffic-related air pollution and cognitive function in a prospective birth cohort in Rome. A cohort of 719 newborns was enrolled in 2003-2004 as part of the GASPII project. At age 7 years, 474 children took the Wechsler Intelligence Scale for Children-III to assess their cognitive development in terms of IQ composite scores. Exposure to air pollutants (NO2, PMcoarse, PM2.5, PM2.5 absorbance) at birth was assessed using land use regression models. We also considered variables indicating traffic intensity. The effect of environmental pollution on IQ was evaluated performing a linear regression model for each outcome, adjusting for gender, child age at cognitive test, maternal age at delivery, parental educational level, siblings, socio-economic status, maternal smoking during pregnancy, and tester. To account for selection bias at enrollment and during follow-up, the regression models were weighted for the inverse probabilities of participation and follow-up. A 10 μg/m³ higher NO2 exposure during pregnancy was associated with 1.4 fewer points (95% confidence interval = -2.6, -0.20) of verbal IQ, and 1.4 fewer points (95% confidence interval = -2.7, -0.20) of verbal comprehension IQ. Similar associations were found for traffic intensity in a 100 m buffer around home. Other pollutants showed negative associations with larger confidence intervals. Consistent with previous evidence, this study suggests an association of exposure to NO2 and traffic intensity with the verbal area of cognitive development.See Video Abstract at http://links.lww.com/EDE/B12.

Colli Albani (Italy) is an alkali-potassic volcanic district located about 20 km SE of Rome (3 M inhabitants) and lastly erupted 36 ka ago. Since the modern volcanic activity at Colli Albani seems not particularly intense, scientists have interpreted this volcano to be quiescent. Therefore, unlike other Italian volcanoes, the area has not undergone extensive monitoring. However, a seismic swarm during 1989-1990 has been related to a local uplift of ca. 30 cm since the 1950's along a line crossing the western side of the volcano, giving rise to a debate about its possible interpretation in terms of unrest. Furthermore, recent geological investigations indicate a coupling of eruption history, uplift history, and changes in the regional stress field, pointing to the conclusion that Colli Albani is in unrest. Here, we investigate the deformation processes and the gas geochemistry (He, CO2 and their isotopic ratios). From the analysis of about 20 years of InSAR data (1992-2010), we retrieve a puzzling deformation field at Colli Albani, consisting of long-term, constant rate, uplift of its western and southern flanks, and by coeval intra-caldera subsidence. This deformation setting cannot be related to a single cause, but reflects the interaction between different and spatially independent dynamic processes. Furthermore, we obtain information on the nature of the sources from the isotopic composition of the discharging CO2 and helium, showing that the Colli Albani dynamics are the result of decoupling between magma intrusion along pre-existing tectonic faults and caldera subsidence. In order to design a comprehensive geophysical model inclusive of all the above reported peculiarities, we consider potential sources related to magma/fluid migration or accumulation processes at depth through the main tectonic structures active at CA, by means of a numerical model. In summary, we demonstrate that despite the present-day phase of caldera deflation, the magmatic system at

Full Text Available This study reveals the arrival of prints and books to the North of Spain acquired by the Italian merchant Antonio Pisano in Rome during a trip of 1582-1583. The voyage was financed thanks to the temporary commercial company established between Pisano and the Genoese Juan Luis de Musante, royal master-builder to Felipe II in Navarre, and both residents in Pamplona. The works include engravings of sacred and profane themes by the most important engravers of the epoch, such as the Dutch Cornelis Cort and the Mantuans Adamo and Diana Ghisi, in addition to books of figures, some by outstanding artists such as Michelangelo or Polidoro da Caravaggio.

Full Text Available BackgroundEructation is a physiologic event which allows gastric venting of swallowed air and most of the time is not perceived as a symptom. This is called gastric belching. Supragastric belching occurs when swallowed air does not reach the stomach and returns by mouth a short time after swallowing. This situation may cause discomfort, life limitations and problems in daily life.ObjectiveOur objective in this investigation was to evaluate if gum chewing increases the frequency of gastric and/or supragastric belches.MethodsEsophageal transit of liquid and gas was evaluated by impedance measurement in 16 patients with complaint of troublesome belching and in 15 controls. The Rome III criteria were used in the diagnosis of troublesome belching. The esophageal transit of liquid and gas was measured at 5 cm, 10 cm, 15 cm and 20 cm from the lower esophageal sphincter. The subjects were evaluated for 1 hour which was divided into three 20-minute periods: (1 while sitting for a 20-minute base period; (2 after the ingestion of yogurt (200 mL, 190 kcal, in which the subjects were evaluated while chewing or not chewing gum; (3 final 20-minute period in which the subjects then inverted the task of chewing or not chewing gum. In gastric belch, the air flowed from the stomach through the esophagus in oral direction and in supragastric belch the air entered the esophagus rapidly from proximal and was expulsed almost immediately in oral direction. Air swallows were characterized by an increase of at least 50% of basal impedance and saliva swallow by a decrease of at least 50% of basal impedance, that progress from proximal to distal esophagus.ResultsIn base period, air swallowing was more frequent in patients than in controls and saliva swallowing was more frequent in controls than in patients. There was no difference between the medians of controls and patients in the number of gastric belches and supragastric belches. In six patients, supragastric belches

Water content in the soil was measured using a Theta Probe Soil Moisture sensor (ML2x by Delta-T-Devices with a direct read-out device that provides soil moisture estimates as percent volume. The correlation between the experimental values obtained by the gravimetricmethod and thevalues directly measured by Theta Probe was found significant. Soil moisture at 100 cm depth indicates soil water as permanently available for plants through the year except during exceptionally dry summer periods. Therefore, oaks experienced no water deficiency with normal rainfall rates, possibly suffering root asphyxia during rainy years. Results are collected in fenced areas, sheltered by the action of the local fauna.

Full Text Available Abstract Background In acute stage of cerebral infarction, MRI indices (rDWI & rADC deteriorate during the first 3-7 days after the ictus and then gradually normalize in approximately 10 days (pseudonormalization time, although the tissue is already infarcted. Since effective treatments improve these indices significantly and in less than the natural pseudonormalization time, a combined analysis of these changes provides an opportunity for objective evaluation on the effectiveness of various treatments for cerebral infarction. Hydroxyl radicals are highly destructive to the tissue and aggravate cerebral infarction. We treated brainstem infarction patients in acute stage with hydroxyl radical scavengers (Edaravone and hydrogen by intravenous administration and evaluated the effects of the treatment by a serial observation and analysis of these MRI indices. The effects of the treatment were evaluated and compared in two groups, an Edaravone alone group and a combined group with Edaravone and hydrogen, in order to assess beneficial effects of addition of hydrogen. Methods The patients were divided in Edaravone only group (E group. 26 patients and combined treatment group with Edaravone and hydrogen enriched saline (EH group. 8 patients. The extent of the initial hump of rDWI, the initial dip of rADC and pseudo-normalization time were determined in each patient serially and averages of these data were compared in these two groups and also with the natural course in the literatures. Results The initial hump of rDWI reached 2.0 in the E group which was better than 2.5 of the natural course but was not as good as 1.5 of the EH group. The initial dip of rADC was 0.6 in the E group which was close to the natural course but worse than 0.8 of the EH group. Pseudonormalization time of rDWI and rADC was 9 days only in EH group but longer in other groups. Addition of hydrogen caused no side effects.

Clement’s New Clothes. The Destruction of Old S. Clemente in Rome, the Eleventh-Century Frescoes, and the Cult of (AntiPope Clement III

Directory of Open Access Journals (Sweden)

Lila Yawn

Full Text Available In the early 1100s, the fifth-century church of S. Clemente in Rome was buried beneath an entirely new basilica.  Inspired by suggestions published by Tommaso di Carpegna Falconieri (1998 and Valentino Pace (2007, the present article considers the possibility that this radical intervention constituted an act of damnatio memoriae or, better, of deletio memoriae, an obliteration of memory prompted by the nascent cult of miracles associated with Pope Paschal II’s enemy and rival, (antipope Clement III.  Clement III (Wibert of Ravenna died in 1100, not long after the execution of an extensive fresco cycle in the early Christian basilica celebrating the miracles and cult of the first-century pope and martyr St. Clement I of Rome.  Resonances between these images and the prodigia attributed to Clement III may have invited analogies between the two Clements, especially during the turbulent early years of Paschal II’s pontificate, when Paschal, alarmed by reports of his adversary’s miracles, had Clement III’s corpse exhumed and thrown into the Tiber. The perceived correspondences between the first-century pope and his eleventh-century namesake may have extended to their postmortem resting places – Clement I was martyred by being thrown into the Black Sea – as well as to their shared attributes, particularly the pontifical vestments and white hair prominently displayed in the frescoes. These attributes disappear in the early twelfth-century mosaic of Clement I on the apsidal arch of the new, upper church, where the saint is instead represented as a young man with dark hair, a dark beard, and an apostle’s clothing.  This extreme makeover in a work securely associable with Roman reform-party sponsorship effectively dissociated Clement I from the painted images in the earlier church and, very probably, from his eleventh-century namesake in the Tiber.

A dynamic city-wide air pollution exposure assessment study has been carried out for the urban population of Rome, Italy, by using time resolved population distribution maps, derived by mobile phone traffic data, and modelled air pollutants (NO2, O3 and PM2.5) concentrations obtained by an integrated air dispersion modelling system. More than a million of persons were tracked during two months (March and April 2015) for their position within the city and its surroundings areas, with a time resolution of 15 min and mapped over an irregular grid system with a minimum resolution of 0.26 × 0.34 Km2. In addition, demographics information (as gender and age ranges) were available in a separated dataset not connected with the total population one. Such BigData were matched in time and space with air pollution model results and then used to produce hourly and daily resolved cumulative population exposures during the studied period. A significant mobility of population was identified with higher population densities in downtown areas during daytime increasing of up to 1000 people/Km2 with respect to nigh-time one, likely produced by commuters, tourists and working age population. Strong variability (up to ±50% for NO2) of population exposures were detected as an effect of both mobility and time/spatial changing in pollutants concentrations. A comparison with the correspondent stationary approach based on National Census data, allows detecting the inability of latter in estimating the actual variability of population exposure. Significant underestimations of the amount of population exposed to daily PM2.5 WHO guideline was identified for the Census approach. Very small differences (up to a few μg/m3) on exposure were detected for gender and age ranges population classes.

We present preliminary results of a multidisciplinary geophysical investigation applied to the subsoil imaging of the archaeological site of Cocciano, near Rome. The area was place of a series of archaeological findings, which are generally recognized as the remains of a vast Roman villa of the imperial age, notably attributed to Emperor Tiberius. We acquired capacitive coupled resistivity data along two parallel profiles and we performed a magnetic survey over a small subset of the survey area. The recovered resistivity models suggest the presence of a shallow, sub-horizontal, resistive layer (ρ > 350 Ωm), of slightly variable thickness (2 - 3 m), which we interpret as the response of ancient substructions overlying a relatively low-resistive layer, which we ascribe to the geological substratum. Processed magnetic data show a clear magnetic signature aligned to form a curve-shaped anomaly right at the prosecution of a nearby, partially exposed, ancient wall.

2006-01-01

Currently, there is a strong demand for efficient seawater desalination plants, which can meet the tougher environment regulation and energy saving requirements. From this standpoint the present work was undertaken to include proposed scheme (solar Fired Combined Reverse Osmosis (ROY Multi-Effect Distillation (MED) Seawater desalination Plant (SCDP) integrated with electrical power grid (EPG)) for repowering and modification of the conventional grid connected RO desalination plants. The model of SCDP during sunny periods may be applied to the following modes operation: *Full solar desalination (i.e. solar thermal and electrical power generation in solar plant is elivered to the desalination process and the surplus electricity is fed into EPG). *Hybrid solar desalination (I.e. a small share of the electrical power consumption for desalination process compensated by EPG). During cloudly periods and at night the SCDP operates as a conventional RO desalination plant. To establish the range, in which solar energy for seawater desalination would be competitive to fossil energy and investigates the potential effect of the proposed scheme on the repowering effectiveness, mathematical model has been developed.

Background: in Europe homelessness is a known risk factor both for active and latent tuberculosis (TB. In Rome 409 cases of TB were notified in 2004, but the real occurrence among homeless people is unknown. Tuberculosis surveillance has been organized with the aim to develop an integrated model for the risk evaluation and management of both Latent Tuberculosis infections (LTBI and TB in Rome homeless people.

Methods: the eligible individuals have been recruited in the homeless’ refuges. The Tuberculin Mantoux test has been used to evaluate the infection prevalence; in case of a positive result, the individual’s expectorate has been collected and the chest X-ray has been performed. A collecting data form has been filled in for evaluating some risk factors. Multiple logistic regression models have been carried out to find statistically significant determinants of infection.

Results: out of 120 subjects recruited, 108 came back for the evaluation of the skin test; the prevalence of LTBI was 43.5% (47/108 subjects; no active TB cases were found. According to the multivariate analysis, factors significantly associated to LTBI are gender (for males OR = 4.94; 95% CI: 1.46 – 16.67, 1st model; OR 5.84; 95% CI: 1.26 – 21.10, 2nd model, birth place (for Europe: OR 3.05; 95% CI: 1.02 – 9.13, 1st model; OR 3.12; 95% CI: 1.10 – 8.88, 2nd model; for East Mediterranean native Region OR = 4.34; 95%CI: 1.15-16.39; Body Mass Index class (for obesity OR = 3.34; 95% CI:1.31-8.51.

Conclusions: these preliminary results have demonstrated a high prevalence of LTBI among homeless people. Male gender, birth place (Europe and East Mediterranean native Region and obesity were found to be significant risk factors. The surveillance system allowed positive patients for LTBI to be rapidly directed to a specialized centre for the clinical evaluation and the appropriate therapy

The Aggradational Successions of the Aniene River Valley in Rome: Age Constraints to Early Neanderthal Presence in Europe

Science.gov (United States)

Ceruleo, Piero; Pandolfi, Luca; Petronio, Carmelo; Rolfo, Mario F.; Salari, Leonardo

2017-01-01

We revise the chronostratigraphy of several sedimentary successions cropping out along a 5 km-long tract of the Aniene River Valley in Rome (Italy), which yielded six hominin remains previously attributed to proto- or archaic Neanderthal individuals, as well as a large number of lithic artefacts showing intermediate characteristics somewhere between the local Acheulean and Mousterian cultures. Through a method of correlation of aggradational successions with post-glacial sea-level rises, relying on a large set of published 40Ar/39Ar ages of interbedded volcanic deposits, we demonstrate that deposition of the sediments hosting the human remains spans the interval 295–220 ka. This is consistent with other well constrained ages for lithic industries recovered in England, displaying transitional features from Lower to Middle Paleolithic, suggesting the appearance of Mode 3 during the MIS 9-MIS 8 transition. Moreover, the six human bone fragments recovered in the Aniene Valley should be regarded as the most precisely dated and oldest hominin remains ascribable to Neanderthal-type individuals in Europe, discovered to date. The chronostratigraphic study presented here constitutes the groundwork for addressing re-analysis of these remains and of their associated lithic industries, in the light of their well-constrained chronological picture.

In this study, forecast errors in dust vertical distributions were analyzed. This was carried out by using quantitative comparisons between dust vertical profiles retrieved from lidar measurements over Rome, Italy, performed from 2001 to 2003, and those predicted by models. Three models were used: the four-particle-size Dust Regional Atmospheric Model (DREAM), the older one-particle-size version of the SKIRON model from the University of Athens (UOA), and the pre-2006 one-particle-size Tel Aviv University (TAU) model. SKIRON and DREAM are initialized on a daily basis using the dust concentration from the previous forecast cycle, while the TAU model initialization is based on the Total Ozone Mapping Spectrometer aerosol index (TOMS AI). The quantitative comparison shows that (1) the use of four-particle-size bins in the dust modeling instead of only one-particle-size bins improves dust forecasts; (2) cloud presence could contribute to noticeable dust forecast errors in SKIRON and DREAM; and (3) as far as the TAU model is concerned, its forecast errors were mainly caused by technical problems with TOMS measurements from the Earth Probe satellite. As a result, dust forecast errors in the TAU model could be significant even under cloudless conditions. The DREAM versus lidar quantitative comparisons at different altitudes show that the model predictions are more accurate in the middle part of dust layers than in the top and bottom parts of dust layers.

: Gastrointestinal (GI) disorders in early life contribute to a lower quality of life and more persistent GI symptoms during the rest of life. Epidemiologic data on adolescence GI disorders are scarce. We aimed to perform a population-based study to assess the prevalence of GI symptoms in adolescents and their relation to sex, age, and socioeconomic status. : A multistage random sample of Tehran middle and high school students (ages 14-19 years) was selected. A validated Persian version of the Rome II questionnaire was used to measure the frequency of different GI disorders as well as demographic socioeconomic variables. : A total of 1436 participants were enrolled in the study, 736 (51.3%) of whom were men. Mean (SD) age was 16.9 (1.8) years. The frequency of at least 1 GI symptom was 32.4%. The 4 most prevalent GI symptoms were bloating (16.9%), heartburn (4.9%), incontinence (4.3%), and irritable bowel syndrome (4.1%). Bloating, irritable bowel syndrome, and proctalgia fugax were significantly more common in girls (P < 0.05). Incontinence was significantly more prevalent in lower socioeconomic status levels (P = 0.01). In logistic regression, age was a risk factor for abdominal bloating and dysphagea and a protective factor for incontinence. : Our study indicates that GI symptoms are common among adolescents. Girls are more prone to these disorders. Special psychological and medical interventions are necessary for high-risk groups.

This paper compares MR perfusion/diffusion-derived parameters with microsphere determination of asymmetry of renal perfusion in a dog model of renal artery stenosis. A left renal artery stenosis was created by placement of a silk ligature. Nb-95-labeled microspheres were injected into the left ventricle, and a reference blood sample was drawn. The dog was imaged in a 1.5-T MR imager with both spin-echo and turbo-FLASH perfusion/diffusion-sensitive pulse sequences. The kidneys were excised, weighted, divided into sections, and counted. Two dogs have been studied to date. In dog 1, left renal blood flow (RBF) was 42 mL/min/100g and right RBF was 337 mL/min/100g. In dog 2 left RBF was 444 mL/min/100g and right RBF was 608 mL/min/100g. The apparent diffusion coefficients (ADC) reflected the asymmetry of flow in dog 1 for both spin-echo and turbo-FLASH sequences (RADC/LADC = 1.7) and showed essentially equal flow in dog 2(RADC/LADC = 0.7)

Knowledge of the frequency of contact between a mosquito species and its different hosts is essential to understand the role of each vector species in the transmission of diseases to humans and/or animals. However, no data are so far available on the feeding habits of Aedes albopictus in Italy or in other recently colonized temperate regions of Europe, due to difficulties in collecting blood-fed females of this diurnal and exophilic species. We analyzed Ae. albopictus host-feeding patterns in two urban and two rural sites within the area of Rome (Italy). Ae. albopictus was collected using sticky-traps and the blood-meal origin of 303 females was determined by direct dot-ELISA. The blood-fed sample, although representing only 4% of the total Ae. albopictus collected, demonstrates the useful application of sticky-trap in studying the feeding behavior of the species. The human blood index was significantly different among sites, ranging from 79-96% in urban sites to 23-55% in rural sites, where horses and bovines represented the most bitten hosts. The results obtained confirm the plastic feeding behavior shown by Ae. albopictus in its original range of distribution and highlights the high potential of this species as a vector of human pathogens in urban areas of Italy, where both humans and the mosquito itself may reach very high densities.

In this multidisciplinary contribution, several diagnostic tests were carried out in order to characterize the stone materials, forms of alteration, and protective products applied in the past to two monumental tombs located in the Protestant Cemetery of Rome (Italy). The Protestant Cemetery is a very important historic site, and has been included in the List of 100 Most Endangered Sites in the World since 2005. In this work, two of its tombs were studied: those of Karl (or Charles) Brjullov, a Russian painter who lived in the first half of the nineteenth century, and of Lady Elisa Temple, wife of the artist Sir Grenville Temple. The tombs are both made of white marble and travertine, and the same forms of alteration and degradation, such as blackish biological patinas, black crusts, and chromatic alterations, were found on both monuments. Petrographic analysis of the different lithotypes made it possible to determine textural characteristics, evaluate the state of preservation, and formulate some hypotheses about their provenance by means of oxygen and carbon isotopic ratios, and evaluation of maximum grain size (MGS) and shape preferred orientation (SPO) of calcite grains. Laboratory culture analysis identified autotrophic species and, in some cases, black patinas caused by fungal species were found. Lastly, Fourier transform infrared spectroscopy (FT-IR) revealed that some synthetic protective products had been used in previous, undocumented restoration processes on some portions of both graves.

THE BEST ATHLETES IN ANCIENT ROME WERE VEGETARIAN!

Full Text Available The figure of gladiators recalls the ideas of strength, hard training, endurance, and deadly efficiency: a perfect fighting machine. Historically, a gladiator was a sort of sport hero, and gladiator's medicine probably one of the first forms of organised sports medicine. Statues and paintings of the ancient roman period tell us of this astonishing world of fighters. There are traces of famous gladiators all over the known world at Roman times, resembling our Mohammad Ali or Mike Tyson. Most of them grew up in fighting schools, the most famous in Capua, near Naples in Italy: Spartacus, the rebel gladiator who inflicted a severe defeat to Roman army, came from there. Gladiators had to endure long session of training to fight in the arena. Considering the modern diets of strength athletes, we should expect that gladiators had a high protein diet. However, analysis of their bones has put forward the hypothesis that gladiators were vegetarian athletes: in his accounts of Rome, the ancient historian Plinius refers to gladiators as "hordearii" (barley-eaters (Eichholz et al., 1938. Plants contain higher levels of strontium than animal tissues. People who consume more plants and less meat will build up measurably higher levels of strontium in their bones. Levels of strontium in the gladiators' bones were two times as high than the bones of contemporary Ephesians (Kanz and Grossschmidt, 2007. Roman army troopers, the "legionnaires", had daily expenditure of energy that can be estimated at around 5000 kcal for the legionnaire performing engineer work and at 6000 kcal for the legionnaire in war action. At present, only workmen and sportsmen reach such levels of energy expenditure (Fornaris and Aubert, 1998. Legionnaires were able to endure long war campaignes and endless "magnis itineribus" (forced marches with incredible resistance to fatigue. The legionnaire's daily ration consisted of 78% carbohydrates, mainly from wheat or barley. This diet has the

Direct radiative effects by anthropogenic particles at a polluted site: Rome (Italy)

International Nuclear Information System (INIS)

Bergamo, A.; De Tomasi, F.; Perrone, M.R.

2008-01-01

The direct radiative effect (DRE) by all (anthropogenic plus natural) and anthropogenic aerosols is calculated at the solar (0.34 μm) and infrared (4-200 μm) spectral range to better address the annual cycle of the anthropogenic aerosols impact at a site (Rome, Italy) significantly affected by pollution. Aerosol optical and microphysical properties from 2003 AERONET Sun/sky-photometer measurements and solar albedos based on MODIS satellite sensor data constitute the necessary input to radiative transfer simulations. Clear- and all-sky conditions are investigated by adopting ISCCP monthly products for high-, mid-and low-cloud cover. It is shown that monthly mean values of aerosol optical depths by anthropogenic particles (AOD a ) are on average more than 50% of the corresponding all-aerosol-optical-depth (AOD) monthly means. In particular, the AOD a /AOD ratio that varies within the (0.51-0.83) on autumn-winter (A W, October-March), varies within the (0.50-0.71 range on spring-summer (S S, April-September) as a consequence of the larger contribution of natural particles on S S. The surface (sfc), all-sky DRE by anthropogenic particles that is negative all year round at solar wave-lengths, represents on average 60% and 51% of the all-sky sfc-DRE by all aerosols on A W and S S, respectively. The all-sky atmospheric forcing by anthropogenic particles (AF a ) that is positive all year round, is little dependent on seasons: it varies within the (1.0-4.1) W/m 2 and (2.0-4.2) W/m 2 range an A W and S S, respectively. Conversely, the all-sky A F by all aerosols is characterized by a marked seasonality. As a consequence, the atmospheric forcing by anthropogenic particles that on average is 50% of the A F value on A W, decreases down to 36% of the A F value on S S. Infrared aerosols DREs that are positive all year round are significantly smaller than the corresponding absolute values of solar DREs. Clouds decrease on average ToA- and sfc-DRE absolute values by anthropogenic

Variations in healthcare provision around the world may impact how patients with functional gastrointestinal disorder (FGIDs) are investigated, diagnosed, and treated. However, these differences have not been reviewed. The Multinational Working Team of the Rome Foundation, established to make recommendations on the conduct of multinational, cross-cultural research in FGIDs, identified seven key issues that are analyzed herein: (i) coverage afforded by different healthcare systems/providers; (ii) level of the healthcare system where patients with FGIDs are treated; (iii) extent/types of diagnostic procedures typically undertaken to diagnose FGIDs; (iv) physicians' familiarity with and implementation of the Rome diagnostic criteria in clinical practice; (v) range of medications approved for FGIDs and approval process for new agents; (vi) costs involved in treating FGIDs; and (vii) prevalence and role of complementary/alternative medicine (CAM) for FGIDs. Because it was not feasible to survey all countries around the world, we compared a selected number of countries based on their geographical and ethno-cultural diversity. Thus, we included Italy and South Korea as representative of nations with broad-based coverage of healthcare in the population and India and Mexico as newly industrialized countries where there may be limited provision of healthcare for substantial segments of the population. In light of the paucity of formal publications on these issues, we included additional sources from the medical literature as well as perspectives provided by local experts and the media. Finally, we provide future directions on healthcare issues that should be taken into account and implemented when conducting cross-cultural and multinational research in FGIDs. © 2014 John Wiley & Sons Ltd.

Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by L1, L2, L3 serovars of C. trachomatis (CT). Since 2003, LGV cases have been increasing in Europe. Aim of this report is to describe the LGV cases diagnosed in the largest STI center in Rome, Italy, from 2000 to 2016. This report shows that two clinically and epidemiologically different series of cases exist, and that, at present, the ano-rectal LGV represents the clinical variant occurring more frequently among men having sex with men (MSM), particularly those HIV-infected. Ten cases of LGV were observed. Three were diagnosed in 2009 in HIV-negative heterosexuals patients that presented the classical genito-ulcerative form with lymphadenopathy. Seven cases were observed in 2015-2016 in HIV-infected MSM, that presented the rectal variant and L2b serovar infection; 4 of these had been misclassified as a chronic bowel disease. Chlamydia infection was confirmed by CT-specific PCR (ompA gene nested PCR), followed by sequence analysis to identify the serovar. All the patients were treated with doxycycline for 3 weeks, obtaining a complete response with healing of both clinical symptoms and dermatological lesions. Our findings suggest that, in case of persistent rectal symptoms in HIV-infected MSM, LGV should be taken into account and investigated through molecular analyses, in order to achieve a correct diagnosis and management of the patients.

This brief examines the development of the first Danish Air Force Air Operations Doctrine, which was officially commissioned in October 1997 and remained in effect until 2010. The development of a Danish air power doctrine was heavily influenced by the work of Colonel John Warden (USAF), both...... through his book ”The Air Campaign” and his subsequent planning of the air campaign against Iraq in 1990-1991. Warden’s ideas came to Denmark and the Danish Air Force by way of Danish Air Force students attending the United States Air Force Air University in Alabama, USA. Back in Denmark, graduates from...... the Air University inspired a small number of passionate airmen, who then wrote the Danish Air Operations Doctrine. The process was supported by the Air Force Tactical Command, which found that the work dovetailed perfectly with the transformation process that the Danish Air Force was in the midst...

Full Text Available In Italy the illicit substances routinely tested are cannabinoids, cocaine, opiates, amphetamines / methamphetamine, MDMA and similar but these substances are not the most use in our country. In particular, the consumption of ketamine represents an emerging problem. Ketamine is a anesthetic with hallucinogenic and dissociative effects and these are the ones sought for the voluptuary pur-pose, while the amnesic effect are exploited for drug facilitated sexual assault. Our study was car-ried out to assess the positivity for the illicit substances routinely tested and also for ketamine in a population of 182 patients arrived at the emergency room of the Hospital “San Camillo Forlanini” of Rome, for which have been required toxicological tests on the basis of Articles 186 and 187 of the New Highway Code.The choice of this kind of population allows to have an accurate and reliable epidemiological data about the real diffusion of voluptuary use of drugs. The study examines 182 samples subjected to routine toxicological investigations in the period be-tween October 2011 and August 2012. The Authors have researched the presence of ethanol, cannabinoids, cocaine, opiates, amphetamines and benzodiazepines with the use of “ADVIA Chemistry Systems ”, while the ketamine is tested by a single-phase tests on urine [Sure Screen Diagnostic (Di. Ra.Lab] with a cut-off level of this method is 1000ng/ml. During this period we have considered 182 patients (males 78%, females 22%.

Intra-arterial revascularization therapy (IART) for acute ischemic stroke has become increasingly popular recently. However, early change in apparent diffusion coefficient (ADC) values after full recanalization in human stroke has not received much attention. The aim of this study was to evaluate ADC changes immediately after interventional full-recanalization in patients with acute ischemic stroke. ADC values of 25 lesions from 18 acute ischemic stroke patients were recorded with both pre- and post-recanalization ADC maps. Measurement was done by placing region of interests over the representative images of the lesion. For analysis, lesions were divided into territorial infarction (TI) and watershed infarction (WI). Mean ADC values of the overall 25 lesions before IART were 415.12 × 10-6 mm 2 /sec, and increased to 619.08 × 10-6 mm 2 /sec after the IART. Average relative ADC (rADC) value for 22 TI increased from 0.59 to 0.92 (p < 0.000), whereas, average rADC value for 3 WI did not change significantly. There was a conspicuous increase of ADC values immediately after full-recanalization in TI lesions. On the other hand, WI lesions did not show significant change in ADC values after recanalization

[Plinius and Greek physicians in Rome: the concept of nature and medical critique in Naturalis Historia].

Hahn, J

1991-01-01

Pliny's historical outline of the development of medicine, in Natural History 29.1-27, is our primary source concerning the reception of scientific medicine at Rome during the later Republic and early Empire. Here, as elsewhere, Pliny handles Greek doctors and their medical practices with vehement disapproval. But this attitude, at first glance anti-Hellene, traditionalistic, and critical of his coevals, arises from more deeply rooted notions: a specific conception of nature which can be shown to be the basis of Pliny's critique of medicine and his own times. Reconstruction of this "Plinean" conception reveals a view of nature marked by Stoic terminology and categories, though in fact derivate from various sources, idiosyncratic and characterized by a genuine love of and respect for nature and her creations. True comprehension of the lessons offered by nature, resulting in concrete mores of behaviour and moral categories, as opposed to theory and speculation, is the proper modus operandi for Pliny. And thus, with regard to the human process of self-discovery in the natural world, medicine plays a decisive role--for providential nature displays herself most clearly in the production of healing substances. Pliny notes among the proponents of scientific medicine, a general disregard for nature and her rules, while he finds just the opposite in traditional medicine. His own accomplishment resides not only in the safeguarding of numberless recipies from the world of folk medicine, but also in the facts that he under-pins these traditional methods of healing, and their basic principles, with a specific conception of nature, and that he marks out an exceptionally important place for traditional methods of healing in the canon of general knowledge.

the Hippocratic ideas that diseases are a result of mood imbalance. Results: Differing from the current Hippocratic idea, only in extreme cases he prescribed medications and bloodletting, two of the most-used therapies of that time. He usually prescribed therapies based on the Epicurean thought, then consisting of walks and music, massages, and thermal baths.

Analysis of inhalatory exposure to air pollution is an important area of investigation when assessing the risks of air pollution for human health. Inhalatory exposure research focuses on the exposure of humans to air pollutants and the entry of these pollutants into the human respiratory tract. The principal grounds for studying the inhalatory exposure of humans to air pollutants are formed by the need for realistic exposure/dose estimates to evaluate the health effects of these pollutants. The AirPEx (Air Pollution Exposure) model, developed to assess the time- and space-dependence of inhalatory exposure of humans to air pollution, has been implemented for use as a Windows 3.1 computer program. The program is suited to estimating various exposure and dose quantities for individuals, as well as for populations and subpopulations. This report describes the fundamentals of the AirPEx model and provides a user manual for the computer program. Several examples included in the report illustrate the possibilities of the AirPEx model in exposure assessment. The model will be used at the National Institute of Public Health and the Environment as a tool in analysing the current exposure of the Dutch population to air pollutants. 57 refs.

The impact of air movement on perceived air quality (PAQ) and sick building syndrome (SBS) symptoms was studied. In total, 124 human subjects participated in four series of experiments performed in climate chambers at different combinations of room air temperature (20, 23, 26 and 28 °C), relative...... and the humidity of the room air. At a low humidity level of 30% an increased velocity could compensate for the decrease in perceived air quality due to an elevated temperature ranging from 20 °C to 26 °C. In a room with 26 °C, increased air movement was also able to compensate for an increase in humidity from 30...... humidity (30, 40 and 70%) and pollution level (low and high). Most of the experiments were performed with and without facially applied airflow at elevated velocity. The importance of the use of recirculated room air and clean, cool and dry outdoor air was studied. The exposures ranged from 60. min to 235...

Abdominal pain-related functional gastrointestinal disorders in children include functional dyspepsia, functional abdominal pain, irritable bowel syndrome, and abdominal migraine. We aimed to evaluate a possible association between functional abdominal pain disorders and Helicobacter pylori infection and faecal calprotectin level. Prospective observational study including consecutive children with functional gastrointestinal disorders fulfilling Rome III criteria (cases) and age/sex-matched healthy controls. H pylori has been detected by biopsy-based tests and stool-antigen detection, faecal calprotectin by enzyme-linked immunosorbent assay. A total of 56 cases (27 with functional dyspepsia) and 56 controls were enrolled. H pylori being detected in 17 of 56 cases (30.4%) and 4 of 56 controls (7.1%, odds ratio: 5.7; 95% confidence interval [CI]: 1.8-18.2, P = 0.003). H pylori was detected significantly more frequently in cases with functional dyspepsia (14/27, 51.9% odds ratio: 14.0; 95% CI: 3.9-49.7, P = 0.00001) than in controls and not in cases with other well-recognized functional gastrointestinal complaints (3/29, 10.3%). The median faecal calprotectin level was similar in cases (7.8 μg/g, 95% CI: 7.8-8.4) including those with gastritis, and controls (9.1 μg/g, 95% CI: 7.8-11.3). Gastritis features were more frequent in H pylori-infected and noninfected cases with functional dyspepsia (27/27, 100%) than in cases with other abdominal functional complaints (15/29, 51.7%, P = 0.007). H pylori gastritis and noninfectious gastritis were associated with functional dyspepsia in children referred for abdominal pain-related functional gastrointestinal disorders while faecal calprotectin is not a predictor of gastritis and is similar in children with functional abdominal pain symptoms and in controls.

Full Text Available Abstract A research on micromammals in the area of "Valle dell'Inferno" (in the north-west of Rome was carried out. The study was based on a previous phytosociological survey which describes a Quercus suber population in the valley (a once larger residua1 of a roman cork-tree wood which is now included in the town. Specimens from Rodents (Apodemus sylvaticus, Mus domesticus, Rattus rattus, R. norvegicus, Pitymys savii and Insectivores (Crocidura suaveolens, Erinaceus europaeus were captured by live traps. Most of Insectivores specimens are represented by C. suaveolens. Generally C. suaveolens lives in sympatry with C. leucodon but no specimens of the latter were found in this area. Three different kinds of landscape are present in the "Inferno" valley, namely, the wood, the meadow, and the bottom valley (with high anthropic impact; we have compared these three landscapes with biotic indexes (index of faunistic affinity, index of biocoenotic affinity and index of environmental evaluation. We have also compared through the same indexes, the micromammal fauna of the "Inferno" valley with six other differently polluted localities in Latium, where animals were captured with the same live traps. This area retains its natura1 environment in despite of the high anthropic impact. Riassunto È stato effettuato uno studio sulla micromammalofauna terrestre della Valle dell'Inferno situata a nord-ovest di Roma. Lo studio è basato su una precedente indagine fitosociologica effettuata per la caratterizzazione vegetazionale di una sughereta un tempo molto estesa ed ora racchiusa nell'abitato cittadino. È stato pertanto possibile tracciare, tramite gli indici biotici, una correlazione tra microteriocenosi ed effetti dell'impatto antropico.

Full Text Available Urban forests represent key elements of green infrastructure and provide essential ecosystem services in both the ecological and social spheres. Therefore, forestation planning plays a decisive role in the sustainable development strategies of metropolitan areas and addresses the challenge of maintaining biodiversity while improving human health and well-being. The aim of this work is to present a methodological approach that can be used to identify priorities in urban forest planning and can provide comprehensive responses to ecological and social needs in any metropolitan context. The approach, which is based on interdisciplinary principles of landscape ecology, ecosystem geography and dynamic plant sociology, has been adopted in the Municipality of Rome (Italy. The first step entails defining an ecological framework for forestation plans by means of the ecological land classification and assessment of landscape conservation status. The second step entails setting forestation priorities according to both ecological and social criteria. The application of the method proved to effectively select limited areas requiring intervention within an extensive metropolitan area. Furthermore, it provided responses to sustainability issues such as long-term maintenance of restored habitats, landscape perspective of planning, greening of urban agriculture, improvement in urban resilience, and cost-effective improvement in ecosystem services provision.

Intestinal parasite infections in immigrant children in the city of Rome, related risk factors and possible impact on nutritional status

Directory of Open Access Journals (Sweden)

Manganelli Laura

2012-11-01

Full Text Available Abstract Background Parasitic diseases can represent a social and economic problem among disadvantaged people - even in developed countries. Due to the limited data available concerning Europe, the aims of the present study were to evaluate the presence of parasites in immigrant children and the risk factors favouring the spread of parasites. Subsequently, the possible correlation between nutritional status and parasitic infections was also investigated. Findings A convenience sample of two hundred and forty seven immigrant children (aged 0–15 attending the Poliambulatorio della Medicina Solidale in Rome was examined. Data were collected using structured questionnaires, and parasitological and anthropometric tests were applied. Chi-squared test and binary logistic multiple-regression models were used for statistical analysis. Thirty-seven children (15% tested positive to parasites of the following species: Blastocystis hominis, Entamoeba coli, Giardia duodenalis, Enterobius vermicularis, Ascaris lumbricoides and Strongyloides stercoralis. A monospecific infection was detected in 30 (81% out of 37 parasitized children, while the others (19% presented a polyparasitism. The major risk factors were housing, i.e. living in shacks, and cohabitation with other families (p Conclusions This study shows that parasite infection in children is still quite common, even in a developed country and that children’s growth and parasitism may be related. Extensive improvements in the living, social and economic conditions of immigrants are urgently needed in order to overcome these problems.

Estimation of air quality by air pollution indices

International Nuclear Information System (INIS)

Liblik, Valdo; Kundel, Helmut

1999-01-01

A novel system for estimating the quality of atmospheric air in the over-ground air layer with the help of air pollution indices was developed. The method is based on a comparison of measured or calculated maximum short-term concentrations and average annual concentrations of pollutants with maximum permissible concentrations (with regard to human beings and vegetation). Special air quality estimation scales for residential areas and natural systems are presented. On the basis of the concentration of the substance under study zones of very high, high, rather high, moderate, low and very low air pollution were distinguished in the over-ground layer of the atmosphere. These are projected to land surface for landscape zonation. The application of the system of indices is demonstrated in the analysis of air quality for the towns of Kohtla-Jarve, Johvi and Kivioli (in 1997-1998). A comparative analysis of the air pollution zones distinguished on the basis of emissions and data from bio monitoring yielded satisfactory results. The system of air pollution indices developed enables to process the results of air monitoring in case of pollution fields of complicated composition so that the result for estimating the quality of ambient air in a residential area is easily understood by inhabitants and interpretable with the help of a special scale; analyse temporal changes in the quality of the air in towns, villages and other residential areas and use the results as basis for developing measures for reducing the pollution of ambient air; carry out zonation of large territories on the basis of air pollution levels (spatial air pollution zones are projected on the ground surface) and estimate air quality in places where air monitoring is lacking to forecast the possible effect of air pollution on natural systems (author)

{sup 212}Pb as tracer for PM deposition on urban vegetation

Energy Technology Data Exchange (ETDEWEB)

Voltaggio, Mario; Spadoni, Massimo; Carloni, Serena; Guglietta, Daniela

{sup 212}Pb concentration in outdoor air is closely correlated with fine suspended particulate matter in the atmosphere. Thanks to this association, this isotope can be used to trace the sinking processes of particulate matter due to the vegetation, also providing accurate estimations of the deposition velocity on foliar surfaces. This approach is particularly effective in areas with high thoron fluxes and, consequently, high {sup 212}Pb fluxes from soil. The contribution of vegetation to the improvement of air quality (AQImp) in the municipality area (MA) of Rome (Latium, Italy), almost entirely located on Th-enriched volcanic soils, was estimated by studying {sup 212}Pb deposition velocity on the grasses (0.9–2.5 mm·s{sup −} {sup 1}) and on the most common tree classes, namely conifers (1.5–15 mm·s{sup −} {sup 1}), evergreen (1–4 mm·s{sup −} {sup 1}) and deciduous (0.2–1.5 mm·s{sup −} {sup 1}). {sup 212}Pb activity in outdoor air was determined by gamma spectrometry after air pumping with accumulation on cellulose filters and after collection on artificial electrostatically charged surfaces (ECS). The high {sup 212}Pb activity values obtained from this analysis (0.90 ± 0.6 Bq m{sup −} {sup 3} and 0.58 ± 0.15 Bq m{sup −} {sup 3}, respectively near and far from the soil) are consistent both with the average regional thoron flux from volcanic soils (2.9 · 10{sup 4} Bq m{sup −} {sup 2}·h{sup −} {sup 1}) and with the thoron flux measured in the volcanic soils of the study area. Thoron and {sup 212}Pb fluxes were also measured both in laboratory and in the field under different soil moisture conditions. The total AQImp for the period from September 2014 to September 2015, calculated after the classification of the MA of Rome into six classes of vegetation, provided a value of 0.20 corresponding to 2.3 Tons per day of removed PM{sub 10}. The role of grasslands in the PM{sub 10} removal, the contribution of the vegetation to the

Air pollution has become the world's single biggest environmental health risk, linked to around 7 million deaths in 2012 according to a recent World Health Organisation (WHO) report. The new data further reveals a stronger link between, indoor and outdoor air pollution exposure and cardiovascular diseases, such as strokes and ischemic heart disease, as well as between air pollution and cancer. The role of air pollution in the development of respiratory diseases, including acute respiratory infections and chronic obstructive pulmonary diseases, is well known. While both indoor and outdoor pollution affect health, recent statistics on the impact of household indoor pollutants (HAP) is alarming. The WHO factsheet on HAP and health states that 3.8 million premature deaths annually - including stroke, ischemic heart disease, chronic obstructive pulmonary disease (COPD) and lung cancer are attributed to exposure to household air pollution. Use of air cleaners and filters are one of the suggested strategies to improve indoor air quality. This review discusses the impact of air pollutants with special focus on indoor air pollutants and the benefits of air filters in improving indoor air quality.

Air Consumption Analysis of Air-Jet Weaving

2016-07-01

Full Text Available In Textile industry, production is mostly key concern for Industry owner. This always has attracted researchers and machines manufacturers to make new developments in process and machines. Air-jet is one of the leading and successful highest productive weaving machines. However, it is now well established that due to add of charges of compressed air, manufacturing cost of air-jet weaving machine is higher as compared with rapier and projectile weaving machines. This is why countries having energy issues do not prefer air-jet weaving machines comparing projectile weaving machines. In this regard, several researchers and machine manufacturers have continuously been working to improve the efficiency of air-jet weft insertion. However, industry practice is as important as design made by researchers. The aim of this research is to investigate the air consumption of air-jet weaving on industrial scale practice. In this study, five weaving machine of same manufacturer and model were selected. It was observed that despite of manufacturing same quality of fabric, air consumption was varying almost in all weaving machines. Conventionally, mill workers adopt hit and trial practice in weaving industry including airpressure setting which leads to variation of nozzle pressure. Main reason of disparity of air consumption in air-jet weaving machines may be variation of distance from compressor to weaving machines, number of joints, un-necessary valve opening and pipes leakages cause an increase of compressed air consumption.

Intra-arterial revascularization therapy (IART) for acute ischemic stroke has become increasingly popular recently. However, early change in apparent diffusion coefficient (ADC) values after full recanalization in human stroke has not received much attention. The aim of this study was to evaluate ADC changes immediately after interventional full-recanalization in patients with acute ischemic stroke. ADC values of 25 lesions from 18 acute ischemic stroke patients were recorded with both pre- and post-recanalization ADC maps. Measurement was done by placing region of interests over the representative images of the lesion. For analysis, lesions were divided into territorial infarction (TI) and watershed infarction (WI). Mean ADC values of the overall 25 lesions before IART were 415.12 × 10-6 mm{sup 2}/sec, and increased to 619.08 × 10-6 mm{sup 2}/sec after the IART. Average relative ADC (rADC) value for 22 TI increased from 0.59 to 0.92 (p < 0.000), whereas, average rADC value for 3 WI did not change significantly. There was a conspicuous increase of ADC values immediately after full-recanalization in TI lesions. On the other hand, WI lesions did not show significant change in ADC values after recanalization.

Cross-cultural, multinational research can advance the field of functional gastrointestinal disorders (FGIDs). Cross-cultural comparative research can make a significant contribution in areas such as epidemiology, genetics, psychosocial modulators, symptom reporting and interpretation, extra-intestinal co-morbidity, diagnosis and treatment, determinants of disease severity, health care utilisation, and health-related quality of life, all issues that can be affected by geographical region, culture, ethnicity and race. To identify methodological challenges for cross-cultural, multinational research, and suggest possible solutions. This report, which summarises the full report of a working team established by the Rome Foundation that is available on the Internet, reflects an effort by an international committee of FGID clinicians and researchers. It is based on comprehensive literature reviews and expert opinion. Cross-cultural, multinational research is important and feasible, but has barriers to successful implementation. This report contains recommendations for future research relating to study design, subject recruitment, availability of appropriate study instruments, translation and validation of study instruments, documenting confounders, statistical analyses and reporting of results. Advances in study design and methodology, as well as cross-cultural research competence, have not matched technological advancements. The development of multinational research networks and cross-cultural research collaboration is still in its early stages. This report is intended to be aspirational rather than prescriptive, so we present recommendations, not guidelines. We aim to raise awareness of these issues and to pose higher standards, but not to discourage investigators from doing what is feasible in any particular setting. © 2014 John Wiley & Sons Ltd.

field of territorial development policies, which are increasingly entrusted to local and regional dimension, in which tend to manifest ideas, proposals and initiatives. On the other hand, as regards the national infrastructure policies, the long absence of comprehensive planning documents, which can provide a reference for local authorities and economic operators, has been mirrored in an episodic and often contradictory action. This situation seems to persist despite the profound changes that, since the 90s, have invested "traditional” planning tools in the direction of greater institutional coordination, and despite the EU territorial policies.Thus, large territorial networks eventually take, at most, the role of (probable elements of a "scenario" and not that of strategic development factors.An example of these difficulties is given by the recent territorial plan of the Province of Rome.The article suggests the assumption of the European strategic and multi-level (highly experimental approach, based on the concept of “Territorial Platform”, towards the overcoming of the highlighted problems.

Can a Clean-Air Heat Pump (CAHP) maintain air purification capability when using polluted air for regeneration?

DEFF Research Database (Denmark)

Sheng, Ying; Fang, Lei

2018-01-01

Clean Air Heat Pump (CAHP) was one type of rotary desiccant cooling system which combined a silica gel rotor with a heat pump to achieve air cleaning, dehumidifying and cooling in buildings. Using exhaust air from the conditioned room for regeneration of the silica gel rotor might have an advantage...... on reducing the regeneration air temperature and further improving the energy performance of the CAHP. However, the exhaust air carried a lot of indoor air pollutants. Whether using exhaust air for the regeneration of the silica gel rotor had an impact on the air cleaning performance of the CAHP...... was experimentally studied. The results showed that using the air contained acetone or toluene for regeneration reduced the pollutants removal capability of CAHP with a reduction of approx. 10% in air cleaning efficiency. The energy performance of the CAHP when using exhaust air for regeneration was also evaluated...

The condition of the air in the occupied zone in airconditioned rooms is influenced by the mixing of supply air with room air. When supplying air from the ceiling there is a mixing all over the room, when supplying from the floor or from desks there is a mixing region only in the lower area. Above this their is warm air from which the return air is drawn. For air supply from below the cooling load can be decreased. In combination with the possible enthalpy difference between room air and supply air this decrease of the cooling load influences the necessary air rate. The interdependence of various air conditioning systems and various air temperatures is shown with a computer program. The load factor for various air distribution system at various cooling loads have been measured in a room of (8 x 5)m/sup 2/ x 3m. Experiments in a smaller model room (scale 1:3) showed how the heat was transported from the mixing region to the stratification region. The theoretically gained influence of the supply air jets of the height of the mixing region and on the load rate could be verified by the experiments. For the design of the fresh air rate, experience has been gained by measurements with tracegas (N/sub 2/O) in a third room. In comparing calculations the annual energy consumption has been computed for a building assuming various air conditioning systems and typical operation data. From experience with the existing systems the conclusions have been drawn how air distribution from floor to ceiling can be installed and operated.

Full Text Available We processed X-band COSMO-SkyMed 3-m resolution StripMap HIMAGE time series (March 2011–June 2013 with the Stanford Method for Persistent Scatterers (StaMPS, to retrieve an updated picture of the condition and structural health of the historic centre of Rome, Italy, and neighbouring quarters. Taking advantage of an average target density of over 2800 PS/km2, we analysed the spatial distribution of more than 310,000 radar targets against: (1 land cover; (2 the location of archaeological ruins and restoration activities; and (3 the size, orientation and morphology of historical buildings. Radar interpretation was addressed from the perspective of conservators, and the deformation estimates were correlated to local geohazards and triggering factors of structural collapse. In the context of overall stability, deformation was identified at the single-monument scale, e.g., for the Roman cistern and exedra in the Oppian Hill. Comparative assessment against InSAR processing of C-band imagery (1992–2010 published in the literature confirms the persistence of ground motions affecting monuments and subsidence in southern residential quarters adjacent to the Tiber River, due to the consolidation of compressible deposits. Vertical velocity estimated from COSMO-SkyMed PS exceeds −7.0 mm/y in areas of recent urbanization.

In the past decade, there have been exciting developments in the field of lithium ion batteries as energy storage devices, resulting in the application of lithium ion batteries in areas ranging from small portable electric devices to large power systems such as hybrid electric vehicles. However, the maximum energy density of current lithium ion batteries having topatactic chemistry is not sufficient to meet the demands of new markets in such areas as electric vehicles. Therefore, new electrochemical systems with higher energy densities are being sought, and metal-air batteries with conversion chemistry are considered a promising candidate. More recently, promising electrochemical performance has driven much research interest in Li-air and Zn-air batteries. This review provides an overview of the fundamentals and recent progress in the area of Li-air and Zn-air batteries, with the aim of providing a better understanding of the new electrochemical systems.

Nitrogen fluorescence in air for observing extensive air showers

CERN Document Server

Keilhauer, B; Fraga, M; Matthews, J; Sakaki, N; Tameda, Y; Tsunesada, Y; Ulrich, A

2012-01-01

Extensive air showers initiate the fluorescence emissions from nitrogen molecules in air. The UV-light is emitted isotropically and can be used for observing the longitudinal development of extensive air showers in the atmosphere over tenth of kilometers. This measurement technique is well-established since it is exploited for many decades by several cosmic ray experiments. However, a fundamental aspect of the air shower analyses is the description of the fluorescence emission in dependence on varying atmospheric conditions. Different fluorescence yields affect directly the energy scaling of air shower reconstruction. In order to explore the various details of the nitrogen fluorescence emission in air, a few experimental groups have been performing dedicated measurements over the last decade. Most of the measurements are now finished. These experimental groups have been discussing their techniques and results in a series of \\emph{Air Fluorescence Workshops} commenced in 2002.

The contribution of Saharan-dust advections to both daily and annual PM average values can be significant all over Southern Europe. The most important effects of dust on the number of PM exceedances are mostly observed in polluted areas and large cities. While a wide literature exists documenting episodes of Saharan dust transport towards the Euro-Mediterranean region and Europe in general, a limited number of studies are still available providing statistically significant results on the impact of Saharan dust on the particulate matter loads over the continent. A four-year (2001-2004) study performed in Rome (Italy) found these events to contribute to the average ground PM10 with about 15±10 µg/m3 on about 17% of the days in a year. Since the PM10 yearly average of many traffic stations in Rome is close to 40 μg/m3, these events can cause the PM10 concentration to exceed air quality limit values (50 μg/m3 as daily average) set by the EU Air Quality Directive 2008/50/EC. Although the European legislation allows Member States to subtract the contribution of natural sources before counting PM10 exceedances, definition of an optimal methodology to quantitatively assess such contribution is still in progress. On the basis of the current European Guidelines on the assessment of natural contributions to PM, the DIAPASON project ("Desert-dust Impact on Air quality through model-Predictions and Advanced Sensors ObservatioNs", recently funded under the EC LIFE+ program) has been formulated to provide a robust, user-oriented methodology to assess the presence of desert dust and its contribution to PM levels. To this end, in addition to satellite-based data and model forecasts, the DIAPASON methodology will employ innovative and affordable technologies, partly prototyped within the project itself, as an operational Polarization Lidar-Ceilometer (laser radar) capable of detecting and profiling dust clouds from the ground up to 10 km altitude.

The aim of this study was to show the influence of air conditioning control for microbial contamination of air inside the operating theatres equipped with correctly working air-conditioning system. This work was based on the results of bacteria and fungi concentration in hospital air obtained since 2001. Assays of microbial air purity conducted on atmospheric air in parallel with indoor air demonstrated that air filters applied in air-conditioning systems worked correctly in every case. To show the problem of fluctuation of bacteria concentration more precisely, every sequences of single results from successive measure series were examined independently.

Chronostratigraphic study of the Grottaperfetta alluvial valley in the city of Rome (Italy: investigating possible interaction between sedimentary and tectonic processes

G. Di Giulio

2008-06-01

Full Text Available We carried out geomorphologic and geological investigations in a south-eastern tributary valley of the Tiber River in Rome, the Grottaperfetta valley, aimed to reconstruct its buried geometry. Since results of the geomorphologic study evidenced anomalies of the stream beds, we performed geoelectric and boreholes prospecting to check whether recent faulting, rather than an inherited structural control, possibly contributed to the evolution of the alluvial valley. Vertical offsets of the stratigraphic horizons across adjacent boreholes were evidenced within the Late Pleistocene-Holocene alluvium and its substratum. In order to rule out the effects of irregular geometry of the alluvial deposits, we focussed on sectors where vertical offsets affected all the stratigraphic horizons (alluvium and pre-Holocene substratum, showing an increasing displacement with depth. We identified a site where repeated displacements occur coupled with a lateral variation of soil resistivity, and we drilled an oblique borehole aimed to cross and sample the possible fault zone affecting the terrain. A 7 cm thick granular layer, inclined 50°÷70° on the horizontal, was recovered 5 m b.g., and it was interpreted as the filling material of a fracture. The convergence of the reported features with independent evidence from geoelectric and geomorphologic investigations leads to hypothesize the presence of a faulting zone within the Holocene alluvial terrains and to propose the excavation of a trench to verify this hypothesis.

The NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has been the home of processing, archiving, and distribution services for the Atmospheric Infrared Sounder (AIRS) mission since its launch in 2002 for the global observations of the atmospheric state. Giovanni, a web-based application developed by the GES DISC, provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data without having to download the data. Most important variables, including temperature and humidity profiles, outgoing longwave radiation, cloud properties, and trace gases, from version 6 AIRS product are available on Giovanni. The AIRS is an instrument suite comprised of a hyperspectral infrared instrument AIRS and two multichannel microwave instruments, the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB). As the HSB ceased operation in very early stage of AIRS mission, the AIRS project operates two parallel retrieval algorithms: one using both IR and MW measurements (AIRS+AMSU) and the other using only IR measurements (AIRS-only) for the most time of the mission. The AIRS+AMSU product is better and the variables on Giovanni are from it. However, the generation of AIRS+AMSU product has been suspended since the AMSU instrument anomaly occurred in late 2016. To continue exploring up-to-date AIRS observations, the same set of variables from the AIRS-only product are added on Giovanni by the GES DSIC. This will also support the comparison of AIRS-only with AIRS+AMSU retrievals. In the presentation, we will demonstrate the visualization of AIRS-only product and the plots/statistics of comparison with AIRS+AMSU product using Giovanni.

A new air quality monitoring and early warning system: Air quality assessment and air pollutant concentration prediction.

Science.gov (United States)

Yang, Zhongshan; Wang, Jian

2017-10-01

Air pollution in many countries is worsening with industrialization and urbanization, resulting in climate change and affecting people's health, thus, making the work of policymakers more difficult. It is therefore both urgent and necessary to establish amore scientific air quality monitoring and early warning system to evaluate the degree of air pollution objectively, and predict pollutant concentrations accurately. However, the integration of air quality assessment and air pollutant concentration prediction to establish an air quality system is not common. In this paper, we propose a new air quality monitoring and early warning system, including an assessment module and forecasting module. In the air quality assessment module, fuzzy comprehensive evaluation is used to determine the main pollutants and evaluate the degree of air pollution more scientifically. In the air pollutant concentration prediction module, a novel hybridization model combining complementary ensemble empirical mode decomposition, a modified cuckoo search and differential evolution algorithm, and an Elman neural network, is proposed to improve the forecasting accuracy of six main air pollutant concentrations. To verify the effectiveness of this system, pollutant data for two cities in China are used. The result of the fuzzy comprehensive evaluation shows that the major air pollutants in Xi'an and Jinan are PM 10 and PM 2.5 respectively, and that the air quality of Xi'an is better than that of Jinan. The forecasting results indicate that the proposed hybrid model is remarkably superior to all benchmark models on account of its higher prediction accuracy and stability.

Indoor air quality investigation at air-conditioned and non-air-conditioned markets in Hong Kong

International Nuclear Information System (INIS)

Guo, H.; Lee, S.C.; Chan, L.Y.

2004-01-01

To characterize indoor air quality at the markets in Hong Kong, three non-air-conditioned and two air-conditioned markets were selected for this study. The indoor air pollutants measured included PM 10 (particulate matters with aerodynamic diameter less than 10 μm), total bacteria count (TBC), carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO 2 ) and sulfur dioxide (SO 2 ). The indoor and outdoor concentrations of these target air pollutants at these markets were measured and compared. The effects of air conditioning, temperature/relative humidity variation and different stalls on the indoor air quality were also investigated. The results indicated that all of the average indoor concentrations of PM 10 , TBC, CO and NO 2 at the markets were below the Hong Kong Indoor Air Quality Objectives (HKIAQO) standards with a few exceptions for PM 10 and TBC. The elevated PM 10 concentrations at Hung Hom, Ngau Tau Kok and Wan Chai markets were probably due to the air filtration of outdoor airborne particulates emitted from vehicular exhaust, whereas high concentrations of airborne bacteria at Sai Ying Pun and Tin Shing markets were linked to the use of air conditioning. Correlation analysis demonstrated that indoor bacteria concentrations were correlated with temperature and relative humidity. The operation of air conditioning did not significantly reduce the levels of air pollutants at the markets. However, the higher indoor/outdoor ratios demonstrated that the operation of air conditioning had influence on the levels of bacteria at the markets. It was found that average PM 10 concentration at poultry stalls was higher than the HKIAQO standard of 180 μg/m 3 , and was over two times that measured at vegetable, fish and meat stalls. Furthermore, the concentration of airborne bacteria at the poultry stalls was as high as 1031 CFU/m 3 , which was above the HKIAQO standard of 1000 CFU/m 3 . The bacteria levels at other three stalls were all below the HKIAQO standard

This paper reviews medical activity provided from 1996 to 2000 by the International Radio Medical Centre (Centro Internazionale Radio Medico, C.I.R.M.). C.I.R.M. is a non-profit organization headquartered in Rome and providing freely telemedical advice to ships flying of any flag navigating on all seas of the world, to civil airplanes and to small Italian islands. From 1996 to 2000 C.I.R.M. has assisted 4,982 patients, 4,686 of which (94%) on board ships, 85 on airplanes and 206 on small Italian islands. More than 65% of requests of telemedical advice received by C.I.R.M. were from non-Italian ships. This indicates the really international nature of C.I.R.M.'s activity. The largest number of medical requests come from the Atlantic Ocean, followed by the Mediterranean sea, Indian Ocean and Pacific Ocean. In terms of pathologies assisted, accidents took the first place, followed as main pathologies by gastrointestinal disorders, cardiovascular pathologies, respiratory disorders, infectious and parasitic diseases and nervous system complaints. Analysis of the outcome of C.I.R.M.'s medical activity showed that more than 50% of patients assisted were recovered or improved while assisted by the Centre.

Smoke-free air laws have been implemented in many Kentucky communities to protect the public from the harmful effects of secondhand smoke exposure. The impact of different strengths of smoke-free air laws on indoor air quality was assessed. Indoor air quality in hospitality venues was assessed in seven communities before and after comprehensive smoke-free air laws and in two communities only after partial smoke-free air laws. One community was measured three times: before any smoke-free air law, after the initial partial law, and after the law was strengthened to cover all workplaces and public places with few exemptions. Real-time measurements of particulate matters with 2.5 mum aerodynamic diameter or smaller (PM(2.5)) were obtained. When comprehensive smoke-free air laws were implemented, indoor PM(2.5) concentrations decreased significantly from 161 to 20 microg/m3. In one community that implemented a comprehensive smoke-free law after initially passing a partial law, indoor PM(2.5) concentrations were 304 microg/m3 before the law, 338 microg/m3 after the partial law, and 9 microg/m3 after the comprehensive law. The study clearly demonstrated that partial smoke-free air laws do not improve indoor air quality. A significant linear trend indicated that PM(2.5) levels in the establishments decreased with fewer numbers of burning cigarettes. Only comprehensive smoke-free air laws are effective in reducing indoor air pollution from secondhand tobacco smoke.

Cavitation today is a very important problem that is solved by means of experimental and mathematical methods. The article deals with the generation of cavitation in convergent divergent nozzle of rectangular cross section. Measurement of pressure, flow rate, temperature, amount of dissolved air in the liquid and visualization of cavitation area using high-speed camera was performed for different flow rates. The measurement results were generalized by dimensionless analysis, which allows easy detection of cavitation in the nozzle. For numerical simulation the multiphase mathematical model of cavitation consisting of water and vapor was created. During verification the disagreement with the measurements for higher flow rates was proved, therefore the model was extended to multiphase mathematical model (water, vapor and air), due to release of dissolved air. For the mathematical modeling the multiphase turbulence RNG k-ε model for low Reynolds number flow with vapor and air cavitation was used. Subsequently the sizes of the cavitation area were verified. In article the inlet pressure and loss coefficient depending on the amount of air added to the mathematical model are evaluated. On the basis of the approach it may be create a methodology to estimate the amount of released air added at the inlet to the modeled area.

Monitoring of deformation phenomena affecting urban areas and man-made structures is of key relevance for the preservation of the artistic, archaeological and architectural heritage. The differential SAR interferometry (DInSAR) technique has already been demonstrated to be an effective tool for non-invasive deformation analyses over large areas by producing spatially dense deformation maps with centimetre to millimetre accuracy. Moreover, by exploiting long sequences of SAR data acquired by different sensors, the advanced DInSAR technique referred to as the small baseline subset (SBAS) approach allows providing long-term deformation time series, which are strategic for guaranteeing the monitoring of urban area displacements. In this work, we investigate the effectiveness of the two-scale multi-sensor SBAS-DInSAR approach to detect and monitor displacements affecting historical and artistic monuments. The presented results, achieved by applying the full resolution SBAS technique to a huge set of ERS-1/2 and ENVISAT data, spanning the 1992–2010 time interval and relevant to the city of Rome (Italy), show the capability of this approach to detect and analyse the temporal evolution of possible deformation phenomena affecting historical buildings and archaeological sites. Accordingly, our analysis demonstrates the effectiveness of the full resolution multi-sensor SBAS approach to operate as a surface deformation tool for supporting the study and conservation strategies of the historical, cultural and artistic heritage

The Multi-Ethnic Study of Atherosclerosis and Air Pollution (MESA Air) leveraged the platform of the MESA cohort into a prospective longitudinal study of relationships between air pollution and cardiovascular health. MESA Air researchers developed fine-scale, state-of-the-art air pollution exposure models for the MESA Air communities, creating individual exposure estimates for each participant. These models combine cohort-specific exposure monitoring, existing monitoring systems, and an extensive database of geographic and meteorological information. Together with extensive phenotyping in MESA—and adding participants and health measurements to the cohort—MESA Air investigated environmental exposures on a wide range of outcomes. Advances by the MESA Air team included not only a new approach to exposure modeling but also biostatistical advances in addressing exposure measurement error and temporal confounding. The MESA Air study advanced our understanding of the impact of air pollutants on cardiovascular disease and provided a research platform for advances in environmental epidemiology. PMID:27741981

2015-06-01

Full Text Available Palazzo Valentini, a historical site of Rome׳s Provincial Administration, is located at the heart of the city. The building was purchased in 1827 by Vincenzo Valentini, a banker and consul general of the Prussian Crown. In 1939, with the outbreak of World War II, a fully self-contained, air-raid shelter was built under the courtyard, with an exit tunnel heading onto the Trajan׳s Forum. Archaeological investigations started in 2005 in view of a simple rehabilitation work of the underground level. As work progressed, the sample-plots brought to light new archaeological findings: relics of a huge temple and what remained of two residential houses with thermal baths. We therefore designed an exhibition space with glass surfaces to allow visitors to appreciate the findings while following a path through historical ages: from the 16th-century courtyard to the underground Roman domus (the sumptuous houses of senators and dignitaries of the Roman Empire, with private baths, to the remains of a Roman temple, and all the way to the Trajan׳s Column pedestal by way of the air-raid shelter. Virtual reconstructions, graphic effects, and movies are the means used to revive the hypothetical original appearance of the environments and the daily life of that epoch in order to help us build a prototype of an on-site museum of the third millennium.

1986-01-01

An ordinary air conditioner in a very humid environment must overcool the room air, then reheat it. Mr. Dinh, a former STAC associate, devised a heat pipe based humidifier under a NASA Contract. The system used heat pipes to precool the air; the air conditioner's cooling coil removes heat and humidity, then the heat pipes restore the overcooled air to a comfortable temperature. The heat pipes use no energy, and typical savings are from 15-20%. The Dinh Company also manufactures a "Z" coil, a retrofit cooling coil which may be installed on an existing heater/air conditioner. It will also provide free hot water. The company has also developed a photovoltaic air conditioner and solar powered water pump.

Abstract Zn–air batteries are becoming the promising power sources for portable and wearable electronic devices and hybrid/electric vehicles because of their high specific energy density and the low cost for next‐generation green and sustainable energy technologies. An air electrode integrated with an oxygen electrocatalyst is the most important component and inevitably determines the performance and cost of a Zn–air battery. This article presents exciting advances and challenges related to air electrodes and their relatives. After a brief introduction of the Zn–air battery, the architectures and oxygen electrocatalysts of air electrodes and relevant electrolytes are highlighted in primary and rechargeable types with different configurations, respectively. Moreover, the individual components and major issues of flexible Zn–air batteries are also highlighted, along with the strategies to enhance the battery performance. Finally, a perspective for design, preparation, and assembly of air electrodes is proposed for the future innovations of Zn–air batteries with high performance. PMID:29721418

2018-01-01

The Tiber valley is a prominent feature in the landscape of ancient Rome and an important element for understanding its urban development. However, little is known about the city’s original setting. Our research provides new data on the Holocene sedimentary history and human-environment interactions in the Forum Boarium, the location of the earliest harbor of the city. Since the Last Glacial Maximum, when the fluvial valley was incised to a depth of tens of meters below the present sea level, 14C and ceramic ages coupled with paleomagnetic analysis show the occurrence of three distinct aggradational phases until the establishment of a relatively stable alluvial plain at 6–8 m a.s.l. during the late 3rd century BCE. Moreover, we report evidence of a sudden and anomalous increase in sedimentation rate around 2600 yr BP, leading to the deposition of a 4-6m thick package of alluvial deposits in approximately one century. We discuss this datum in the light of possible tectonic activity along a morpho-structural lineament, revealed by the digital elevation model of this area, crossing the Forum Boarium and aligned with the Tiber Island. We formulate the hypothesis that fault displacement along this structural lineament may be responsible for the sudden collapse of the investigated area, which provided new space for the observed unusually large accumulation of sediments. We also posit that, as a consequence of the diversion of the Tiber course and the loss in capacity of transport by the river, this faulting activity triggered the origin of the Tiber Island.

Estimates for 2010 indicate that infiltration in residential buildings was responsible for 2.85 quads of energy (DOE 2014), which is about 3% of the total energy consumed in the US. One of the mechanisms being implemented to reduce this energy penalty is the use of air barriers as part of the building envelope. These technologies decrease airflow through major leakage sites such as oriented strand board (OSB) joints, and gaps around penetrations (e.g., windows, doors, pipes, electrical outlets) as indicated by Hun et al. (2014). However, most air barrier materials do not properly address leakage spots such as wall-to-roof joints and wall-to-foundation joints because these are difficult to seal, and because air barrier manufacturers usually do not provide adequate instructions for these locations. The present study focuses on characterizing typical air leakage sites in wall assemblies with air barrier materials.

The results of air treatment process modeling at the location of the air curtain in the air suppliers and ventilation shafts

Full Text Available In the existing shaft air heater installations (AHI, that heat the air for air suppliers in cold seasons, a heater channel is used. Some parts of the air from the heater go to the channel, other parts are sucked through a pithead by the general shaft pressure drawdown formed by the main ventilation installation (MVI. When this happens, a mix of two air flows leads to a shaft heat regime violation that can break pressurization of intertubular sealers. The problem of energy saving while airing underground mining enterprises is also very important. The proposed solution of both tasks due to the application of an air curtain is described in the article. In cold seasons the air treatment process should be used and it is offered to place an air curtain in the air suppliers shaft above the place of interface of the calorifer channel to a trunk in order to avoid an infiltration (suction of air through the pithead. It’s recommended to use an air curtain in a ventilation shaft because it reduces external air leaks thereby improving energy efficiency of the MVI work. During the mathematical modeling of ventilation and air preparation process (in SolidWorks Flowsimulation software package it was found out that the use of the air curtain in the air supply shaft can increase the efficiency of the AHI, and reduce the electricity consumption for ventilation in the ventilation shaft.

Regarding global warming issue, one of the impact that is very interesting to be investigated is sea level rise. Sea level rise is predicted has very big impact since, in general, in coastal areas locate a lot of important activities for such city or country. On the context of Indonesian locality, most of big cities such as Jakarta, Surabaya, Semarang, Makasar, etc. are located on the coastal area. Since a lot of important activities located on those cities, in general, sea level rise will influence the development processes of those cities. On the basis of the observation gathering in Surabaya City, the impact of sea level rise will influence not only the development of coastal area but also development of Surabaya City in general. The influence is because the area accommodates activities which are very important in city development both for present and future. The activities are port, industrial estate and location for new housing.

Full Text Available The aim of the study was to determine the microbiological characteristics of air blown from warm air hand dryers, and to compare findings with the microbiological characteristics of indoor air in which the dryer settled. Air samples was taken from different public places (shopping centers, restaurants and hospitals and investigated for total viable counts, coagulase negative Staphylococcus, E. Coli, Staphylococcus aureus and enteric pathogens. There were differences between sampling indoor places for some of the microorganisms, but all of the air samples taken from dryers contained more microorganisms than indoor air, and the differences between hand dryers and indoor air were statistically significant (p<0.05 except for enteric pathogens. As a result it could be said that warm air hand dryers could be microbiological contamination sources in restrooms or the other places that they are used. [TAF Prev Med Bull 2005; 4(1.000: 1-7

Indoor air humidity, air quality, and health - An overview.

Science.gov (United States)

Wolkoff, Peder

2018-04-01

There is a long-standing dispute about indoor air humidity and perceived indoor air quality (IAQ) and associated health effects. Complaints about sensory irritation in eyes and upper airways are generally among top-two symptoms together with the perception "dry air" in office environments. This calls for an integrated analysis of indoor air humidity and eye and airway health effects. This overview has reviewed the literature about the effects of extended exposure to low humidity on perceived IAQ, sensory irritation symptoms in eyes and airways, work performance, sleep quality, virus survival, and voice disruption. Elevation of the indoor air humidity may positively impact perceived IAQ, eye symptomatology, and possibly work performance in the office environment; however, mice inhalation studies do not show exacerbation of sensory irritation in the airways by low humidity. Elevated humidified indoor air appears to reduce nasal symptoms in patients suffering from obstructive apnea syndrome, while no clear improvement on voice production has been identified, except for those with vocal fatigue. Both low and high RH, and perhaps even better absolute humidity (water vapor), favors transmission and survival of influenza virus in many studies, but the relationship between temperature, humidity, and the virus and aerosol dynamics is complex, which in the end depends on the individual virus type and its physical/chemical properties. Dry and humid air perception continues to be reported in offices and in residential areas, despite the IAQ parameter "dry air" (or "wet/humid air") is semantically misleading, because a sensory organ for humidity is non-existing in humans. This IAQ parameter appears to reflect different perceptions among other odor, dustiness, and possibly exacerbated by desiccation effect of low air humidity. It is salient to distinguish between indoor air humidity (relative or absolute) near the breathing and ocular zone and phenomena caused by moisture

Air conditioner

The present invention provides an air conditioner which can prevent an undesirable effects on a human body due to radon daughter nuclides in a closed space. That is, the concentration of the radon daughter nuclides in the air in the closed space is continuously measured. A necessary amount of ventilation air is determined based on the measured concentration to generate control signals. External air is introduced into the closed space by the generated control signals. With such procedures, necessary amount of external air is taken from the atmospheric air which can be regarded to have the radon daughter nuclide concentration substantially at zero, thereby enabling to reduce the concentration of the radon daughter nuclides in the closed space. As a result, undesired effects on the human body due to the radon daughter nuclides staying in the closed space can be prevented. According to simulation, the radon daughter nuclides are rapidly decreased only by ventilation only for three times or so in one hour. Accordingly, ventilation is extremely effective and convenient means as a countermeasure for the radon daughter nuclides. (I.S.)

1992-04-01

In 1992, a clean air strategy will be developed to incorporate views of British Columbians on ways to meet goals related to air quality. A discussion paper is presented to provide information to those interested in participation in developing this strategy. The paper gives information on air quality issues important to the province, including local air quality, urban smog, ozone layer depletion, and global climate change. The views and concerns expressed by stakeholders who attended the Clean Air Conference in 1991 are summarized. The process used to develop the clean air strategy is outlined and some outcomes to be anticipated from the strategy are suggested, including policies and priorities for action to ensure clean air. Air pollutants of concern are total reduced sulfur, mainly from pulp mills and gas processing plants; smoke from wood burning; sulfur dioxide from pulp mills and gas plants; hydrogen fluoride from aluminum smelting; ground-level ozone in urban areas; and acid rain. Elements of a clean air strategy include a smoke management policy, management strategies for greenhouse gases and ozone smog, ozone layer protection measures, regional air quality management plans, and long-term planning efforts in energy use, transportation modes, community design, and land use. 12 refs., 14 figs., 2 tabs

Connectable solar air collectors

Oestergaard Jensen, S.; Bosanac, M.

2002-02-01

The project has proved that it is possible to manufacture solar air collector panels, which in an easy way can be connected into large collector arrays with integrated ducting without loss of efficiency. The developed connectable solar air collectors are based on the use of matrix absorbers in the form of perforated metal sheets. Three interconnected solar air collectors of the above type - each with an transparent area of approx. 3 m{sup 2} - was tested and compared with parallel tests on two single solar air collectors also with a transparent area of approx. 3 m{sup 2} One of the single solar air collectors has an identical absorber as the connectable solar air collectors while the absorber of the other single solar air collector was a fibre cloth. The efficiency of the three solar air collectors proved to be almost identical in the investigated range of mass flow rates and temperature differences. The solar air collectors further proved to be very efficient - as efficient as the second most efficient solar air collectors tested in the IEA task 19 project Solar Air Systems. Some problems remain although to be solved: the pressure drop across especially the connectable solar air collectors is too high - mainly across the inlets of the solar air collectors. It should, however, be possible to considerably reduce the pressure losses with a more aerodynamic design of the inlet and outlet of the solar air collectors; The connectable solar air collectors are easy connectable but the air tightness of the connections in the present form is not good enough. As leakage leads to lower efficiencies focus should be put on making the connections more air tight without loosing the easiness in connecting the solar air collectors. As a spin off of the project a simple and easy way to determine the efficiency of solar, air collectors for pre-heating of fresh air has been validated. The simple method of determining the efficiency has with success been compared with an advance method

The effect of air velocity on heat stress at increased air temperature

DEFF Research Database (Denmark)

Bjerg, B.; Wang, Xiaoshuai; Zhang, Guoqiang

Increased air velocity is a frequently used method to reduce heat stress of farm animals housed in warm conditions. The main reason why the method works is that higher air velocity increases the convective heat release from the animals. Convective heat release from the animals is strongly related...... to the temperature difference between the surfaces of animals and the surrounding air, and this temperature difference declines when the air temperature approaches the animal body temperature. Consequently it can it by expected that the effect of air velocity decreases at increased air temperature. The literature...... on farm animals in warm conditions includes several thermal indices which incorporate the effect of air velocities. But, surprisingly none of them predicts a decreased influence of air velocity when the air temperature approaches the animal body temperature. This study reviewed published investigations...

2002-06-01

This report is intended as a training cum reference document for scientists posted at the Environmental Laboratories at the Nuclear Power Station Sites and other sites of the Department of Atomic Energy with installations emitting air pollutants, radioactive or otherwise. Since a manual already exists for the computation of doses from radioactive air pollutants, a general approach is take here i.e. air pollutants in general are considered. The first chapter presents a brief introduction to the need and scope of air pollution dispersion modelling. The second chapter is a very important chapter discussing the aspects of meteorology relevant to air pollution and dispersion modelling. This chapter is important because without this information one really does not understand the phenomena affecting dispersion, the scope and applicability of various models or their limitations under various weather and site conditions. The third chapter discusses the air pollution models in detail. These models are applicable to distances of a few tens of kilometres. The fourth chapter discusses the various aspects of meteorological measurements relevant to air pollution. The chapters are followed by two appendices. Apendix A discusses the reliability of air pollution estimates. Apendix B gives some practical examples relevant to general air pollution. It is hoped that the document will prove very useful to the users. (author)

Thermal conditions and perceived air quality in an air-conditioned auditorium

Polednik, Bernard; Guz, Łukasz; Skwarczyński, Mariusz; Dudzińska, Marzenna R.

2016-07-01

The study reports measurements of indoor air temperature (T) and relative humidity (RH), perceived air quality (PAQ) and CO2, fine aerosol particle number (PN) and mass (PM1) concentrations in an air conditioned auditorium. The measurements of these air physical parameters have been carried out in the unoccupied auditorium with the air conditioning system switched off (AC off mode) and in the unoccupied and occupied auditorium with the air conditioning system switched off during the night and switched on during the day (AC on/off mode). The average indoor air thermal parameters, CO2 concentration and the PAQ value (in decipols) were elevated, while average PM1 concentration was lower in the AC on/off mode. A statistically significant (p PAQ values and CO2 concentrations (r = 0.66 and r = 0.59, respectively) in that AC mode. A significant negative correlation has been observed between T and PN and PM1 concentrations (r = -0.38 and r = -0.49, respectively). In the AC off mode the above relations between T and the particle concentrations were not that unequivocal. These findings may be of importance as they indicate that in certain AC operation modes the indoor air quality deteriorates along with the variation of the indoor air microclimate and room occupation. This, in turn, may adversely affect the comfort and productivity of the users of air conditioned premises.

An alternative solution is the use of CFD models, developing including the air jets aerodynamics in the premise, the presence of furniture, equipment, transfer of ions under an electric field, and other physical factors, determining intensity and shape of air ions concentration field in the premise. Methodology. Influence of air flow was taken into account in the development of CFD models for calculation of air ion regime in the apartment, caused by operation of ventilation, diffusion, electric field impact, as well as the interaction of different polarity ions with each other, and their interaction with dust particles. The proposed model of calculation of air ion regime in premises based on the use of aerodynamics, electrostatics and mass transfer levels. This model allows operatively to calculate air ions concentration field with the influence of the walls, floor, ceiling and obstacles on the process of air ions dispersion, the specific location of different polarity ions emission and their interaction in the premise and work areas in conditions of artificial air ionization. Results. The calculated data were obtained and on their base could be estimated the concentration of air ion anywhere in the premise with artificial air ionization.

Clean air is considered to be a basic requirement for human health and well-being. To examine the relationship between cognitive performance and ambient pollution exposure. Studies were identified through a systematic search of online scientific databases, in addition to a manual search of the reference lists from the identified papers. Air pollution is a multifaceted toxic chemical mixture capable of assaulting the central nervous system. Despite being a relatively new area of investigation, overall, there is mounting evidence implicating adverse effects of air pollution on cognitive function in both adults and children. Consistent evidence showed that exposure to air pollution, specifically exposure to particulate matter, caused poor age-related cognitive performance. Living in areas with high levels of air pollution has been linked to markers of neuroinflammation and neuropathology that are associated with neurodegenerative conditions such as Alzheimer's disease-like brain pathologies.

Outdoor air pollution is a major environmental health problem affecting all people in developed and developing countries alike. Ambient (outdoor) air pollution in both cities and rural areas was estimated to cause 3.7 million premature deaths worldwide in 2012. In modern society, people are expending an increasing amount of time in polluted urban environments, thus increasing their exposure and associated health responses. Some cities provide information about air pollution levels to their citizens using air quality monitoring networks. However, due to their high cost and maintenance, the density of the monitoring networks is very low and not capable to capture the high temporal and spatial variability of air pollution. Thus, the citizen lacks a specific answer to the question of "how the air quality is in our surroundings". In the framework of the EU-funded CITI-SENSE project the innovative concept of People as Sensors is being applied to the field of outdoor air pollution. This is being done in eight European cities, including Barcelona, Belgrade, Edinburgh, Haifa, Ljubljana, Oslo, Ostrava and Vienna. People as Sensors defines a measurement model, in which measurements are not only taken by hardware sensors, but in which also humans can contribute with their individual "measurements" such as their subjective perception of air quality and other personal observations. In order to collect the personal observations a mobile app, CityAir, has been developed. CityAir allows citizens to rate the air quality in their surroundings with colour at their current location: green if air quality is very good, yellow if air quality is good, orange if air quality is poor and red if air quality is very poor. The users have also the possibility of indicating the source of pollution (i.e. traffic, industry, wood burning) and writing a comment. The information is on-line and accessible for other app users, thus contributing to create an air-quality map based on citizens' perception

Description of system for air concentration measuring in air-steam mixture during the transients is represented. Air concentration measuring is based on discrete sampling method. The measuring system consists of sampler, transport pipeline, distributor and six measuring vessels. From the sampler air-steam mixture comes to distributor through transport pipeline and fills consecutively the measuring vessels. The true air concentration in place of measurement was defined based on measured air concentration in samples taken from measuring vessels. For this purpose, the mathematical model of transients in measuring system was developed. Air concentration transient in air-steam mixture in place of measurement was described in mathematical model by air concentration time-dependent function. The function parameters were defined based on air concentration measured in samples taken from measuring vessels. Estimated error of air concentration identification was about 10%. Measuring system was used in experiments on EREC BKV-213 test facility intended for testing of VVER-440/V-213 reactor barbotage-vacuum system

Air Leakage and Air Transfer Between Garage and Living Space

Energy Technology Data Exchange (ETDEWEB)

Rudd, A.

2014-09-01

This research project focused on evaluation of air transfer between the garage and living space in a single-family detached home constructed by a production homebuilder in compliance with the 2009 International Residential Code and the 2009 International Energy Conservation Code. The project gathered important information about the performance of whole-building ventilation systems and garage ventilation systems as they relate to minimizing flow of contaminated air from garage to living space. A series of 25 multi-point fan pressurization tests and additional zone pressure diagnostic testing characterized the garage and house air leakage, the garage-to-house air leakage, and garage and house pressure relationships to each other and to outdoors using automated fan pressurization and pressure monitoring techniques. While the relative characteristics of this house may not represent the entire population of new construction configurations and air tightness levels (house and garage) throughout the country, the technical approach was conservative and should reasonably extend the usefulness of the results to a large spectrum of house configurations from this set of parametric tests in this one house. Based on the results of this testing, the two-step garage-to-house air leakage test protocol described above is recommended where whole-house exhaust ventilation is employed. For houses employing whole-house supply ventilation (positive pressure) or balanced ventilation (same pressure effect as the Baseline condition), adherence to the EPA Indoor airPLUS house-to-garage air sealing requirements should be sufficient to expect little to no garage-to-house air transfer.

Full Text Available Abstract The conflict between Israel and Palestine on Gaza Strip has caused not only military casualties but also civilian casualties which are protected by the international law. The protection of civilians in armed conflict is basically set in the Geneva Convention of 1949 which has been ratified by Israel and Palestine, in which violations of its provisions constitute war crimes. This paper discusses the mechanism of the International Criminal Court based on the Rome Statute 1998 in enforcing the law against war crimes on Gaza Strip. Articles 13 and 15 of Rome Statute 1998 provide jurisdiction for the settlement of an international criminal case. Palestine has made several attempts in accepting the jurisdiction of the ICC in 2009 and 2015, namely through their declaration and accession which further gave legal implication on the implementation of the international law. Based on these studies, this paper will further discuss the legal implication of the Palestine's declaration in 2009 and 2015, as well as its accession in 2015. Abstrak Konflik yang telah terjadi bertahun-tahun antara Israel dan Palestina di jalur Gaza telah memakan tidak hanya korban militer namun juga korban sipil yang dilindungi oleh hukum internasional.

This paper presents a study aiming at assessing the seismic safety and developing the rehabilitation design of a masonry retaining wall, known as 'Bastione Farnesiano', and placed around the Palatinum hill, in the central archeological area of Rome, in Italy. It is a singular artifact of its kind and hardly identifiable with known stereotypes or constructive models. The phase of survey, together with both the material and degradation analyses, showed the impossibility to define with certainty some features, even geometrical, of the monument, necessary to reach a judgment about its safety. Therefore, it was necessary to formulate the risk assessment problem by taking into due consideration all uncertainties and evaluating them in probabilistic terms. A simple mechanical model, considering different and alternative collapse modes, was developed and, after characterizing the uncertain parameters in probabilistic terms, Monte Carlo simulations were carried out. Based on the obtained results: a) the value of the current risk index has been determined, and b) a sensitivity analysis has been performed in order to identify the parameters that mostly affect the monument safety. This analysis has provided useful information that has allowed to orient the seismic amelioration design strategy by acting on one of the parameters that have greater impact on the risk reduction.

Air pollution is an environmental and a social problem which leads to a multitude of adverse effects on human health and standard of human life, state of the ecosystems and global change of climate. Air pollutants are emitted from natural, but mostly from anthropogenic sources and may be transported over long distances. Some air pollutants are extremely stable in the atmosphere and may accumulate in the environment and in the food chain, affecting human beings, animals and natural biodiversity. Obviously, air pollution is a complex problem that poses multiple challenges in terms of management and abatements of the pollutants emission. Effective approach to the problems of air pollution requires a good understanding of the sources that cause it, knowledge of air quality status and future trends as well as its impact on humans and ecosystems. This chapter deals with the complexities of the air pollution and presents an overview of different technical processes and equipment for air pollution control, as well as basic principles of their work. The problems of air protection as well as protection of other ecosystems can be solved only by the coordinated endeavors of various scientific and engineering disciplines, such as chemistry, physics, biology, medicine, chemical engineering and social sciences. The most important engineering contribution is mostly focused on development, design and operation of equipment for the abatement of harmful emissions into environment.

Air Conditioning Compressor Air Leak Detection by Image Processing Techniques for Industrial Applications

Directory of Open Access Journals (Sweden)

Pookongchai Kritsada

2015-01-01

Full Text Available This paper presents method to detect air leakage of an air conditioning compressor using image processing techniques. Quality of air conditioning compressor should not have air leakage. To test an air conditioning compressor leak, air is pumped into a compressor and then submerged into the water tank. If air bubble occurs at surface of the air conditioning compressor, that leakage compressor must be returned for maintenance. In this work a new method to detect leakage and search leakage point with high accuracy, fast, and precise processes was proposed. In a preprocessing procedure to detect the air bubbles, threshold and median filter techniques have been used. Connected component labeling technique is used to detect the air bubbles while blob analysis is searching technique to analyze group of the air bubbles in sequential images. The experiments are tested with proposed algorithm to determine the leakage point of an air conditioning compressor. The location of the leakage point was presented as coordinated point. The results demonstrated that leakage point during process could be accurately detected. The estimation point had error less than 5% compared to the real leakage point.

THE USE OF AIR LAYERS IN BUILDING ENVELOPES FOR ENERGY SAVING DURING AIR CONDITIONING

Directory of Open Access Journals (Sweden)

S. N. Osipov

2017-01-01

Full Text Available Since there are no large natural energy resources in Belarus, energy savings ought to be a point of the special attention. With this regard it is important to develop modern ways of savings during the process of air conditioning inside new buildings with an air layer in the enclosure, especially in translucent ones. The system of ventilation of air layers in the enclosure of a building has been introduced in which air movement is caused by the gravitational and aerodynamic forces. It makes it possible to arrange further ventilation – a natural, forced or a hybrid one. With the purpose of increasing and streamlining natural draught the partitions are used separating the different parts of air layers. For natural ventilation with the use of gravitational forces the holes in the upper and lower parts of the partitions between adjacent air layers are applied. Natural ventilation in the holes of the partitions is regulated by movable shutters, blinds or other adjusting devices. For combined or forced air exchange between adjacent zones of air layers fans are used pumping air from the air layer zones with a higher temperature to zones of air layers with lower temperature and vice versa. When air exchange is forced, in order to intensify the infiltration of air into zones of air layers jets are laid on a hard surface. In order to cool a multi-layered enclosure of a building, where the movement of air between the air layers (that have been formed by internal partitions is being fulfilled by a natural, forced or combined mode, a part of the air or the total air processed inside the building (i.e. conditioned or non-conditioned air cooler as compared with the outside one is being sent to these strata. Combined or forced flow of the air processed inside the building into the air layers is done through the ducts associated with the output channels of the air conditioners. The internal partitions are equipped with the air valve hole.

A description of Calliope {gamma} irradiation plant of ENEA-Casaccia Centre (Rome) is presented in this paper. In particular the main characteristics of the irradiation facility necessary to define time and irradiation procedure are summarised. The plant is equipped with dosimetric services that evaluate absorbed doses in materials during irradiation. Dosimetric techniques used are Fricke, RedPerspex and alanine-ESR dosimetries. In the first case, absorbed dose is determined by chemical changes induced in a solution by irradiation and the second method uses the optical density increase induced in dosimeter by irradiation. The last method is based on the analysis of the free radical concentration induced in {alpha}-alanine amino-acid during irradiation. The paper provides also a simulation of the {gamma} radiation field inside the irradiation cell realised by using FLUKA code, which includes a good description of the electromagnetic physics down to about 0.1 KeV. [Italian] In questo lavoro viene descritto l'impianto di irraggiamento {gamma} Calliope del Centro Ricerche ENEA-Casaccia (Roma). In particolare vengono riportate le principali caratteristiche dell'impianto di irraggiamento necessarie per definire le modalita di tempo e di irraggiamento. Le tecniche dosimetriche utilizzate sono: la dosimetria di Fricke, la Red-Perspex e quella ESR con alanina. Nel primo caso la dose assorbita e misurata attraverso cambiamenti chimici indotti dalla radiazione in una soluzione mentre nel secondo metodo si utilizza l'aumento della densita ottica del dosimetro dovuto all'irraggiamento. Infine la tecnica ESR ad alanina si basa sull'analisi dei radicali liberi indotti dall' irraggiamento nell' aminoacido {alpha}-alanina. Nel lavoro e anche fornita una simulazione del campo di radiazione all'interno della cella di irraggiamento realizzata con il codice FLUKA, che include l'ottima descrizione dei processi di iterazione elettromagnetici fino ad un'energia di 0.1 KeV.

Functional heartburn is defined by Rome III criteria as an endoscopy-negative condition with normal oesophageal acid exposure time, negative symptom association to acid reflux and unsatisfactory response to proton pump inhibitors. These criteria underestimated the role of non-acid reflux. To assess the contribution of impedance-pH with symptom association probability (SAP) analysis in identifying endoscopy-negative patients with reflux disease and separating them from functional heartburn. Consecutive endoscopy-negative patients treated with proton pump inhibitors (n=219) undergoing impedance-pH monitoring off-therapy were analysed. Distal acid exposure time, reflux episodes, SAP and symptomatic response to proton pump inhibitors were measured. Based on impedance-pH/SAP, 67 (31%) patients were pH+/SAP+, 6 (2%) pH+/SAP-, 83 (38%) hypersensitive oesophagus and 63 (29%) functional heartburn. According to pH-metry alone/response to proton pump inhibitors, 62 (28%) were pH+/SAP+, 11 (5%) pH+/SAP-, 61 (28%) hypersensitive oesophagus and 85 (39%) functional heartburn. In the normal-acid exposure population the contribution of impedance-pH/SAP compared to pH-metry alone/response to proton pump inhibitors in identifying patients with reflux disease and functional heartburn resulted to be 10%. In patients with abnormal-acid exposure, the contribution of impedance-pH/SAP increased by 3%. Comparing impedance-pH testing with pH-metry alone plus the response to proton pump inhibitor therapy demonstrated that the latter ones cause underestimation of reflux disease patients and overestimation of functional heartburn patients.

Increasing the coefficient of performance of air conditioner with air-cooled condenser is a challenging problem especially in area with very hot weather conditions. Application of evaporatively cooled air condenser instead of air-cooled condenser is proposed in this paper as an efficient way to solve the problem. An evaporative cooler was built and coupled to the existing air-cooled condenser of a split-air-conditioner in order to measure its effect on the cycle performance under various ambient air temperatures up to 49 C. Experimental results show that application of evaporatively cooled air condenser has significant effect on the performance improvement of the cycle and the rate of improvement is increased as ambient air temperature increases. It is also found that by using evaporatively cooled air condenser in hot weather conditions, the power consumption can be reduced up to 20% and the coefficient of performance can be improved around 50%. More improvements can be expected if a more efficient evaporative cooler is used. (author)

Controlled air incineration

Seitz, K.A.

1991-01-01

From 1960 to 1970, incineration was recognized as an economical method of solid waste disposal with many incinerators in operation through the country. During this period a number of legislation acts began to influence the solid waste disposal industry, namely, the Solid Waste Disposal Act of 1965; Resource Conservation Recovery Act (RCRA) of 1968; Resource Recovery Act of 1970; and Clean Air Act of 1970. This period of increased environmental awareness and newly created regulations began the closure of many excess air incineration facilities and encouraged the development of new controlled air, also known as Starved-Air incinerator systems which could meet the more stringent air emission standards without additional emission control equipment. The Starved-Air technology initially received little recognition because it was considered unproven and radically different from the established and accepted I.I.A. standards. However, there have been many improvements and developments in the starved-air incineration systems since the technology was first introduced and marketed, and now these systems are considered the proven technology standard

Oxidation behavior of stainless steel 430 and 441 at 800 C in single (air/air) and dual atmosphere (air/hydrogen) exposures

Intermediate temperature ({proportional_to}800 {sup o}C) planar solid oxide fuel cells (SOFCs) allow the use of ferritic stainless steel (FSS) interconnects. SOFC FSS interconnects are used to stack individual cells into series, and are simultaneously exposed to air on the cathode side and fuel on the anode side, creating a 'dual atmosphere' exposure. The thermally grown oxide (TGO) layers on the air side of FSSs 430 and 441 were analyzed as a function of simulated dual atmosphere exposures (moist air/moist hydrogen) for up to 300 h. FSS 430 showed some changes in oxidation behavior, with a slight Fe concentration increase and localized Fe{sub 2}O{sub 3} nodule formation observed in the dual atmosphere TGO layer relative to its single atmosphere (air/air) counterpart. Significantly accelerated and anomalous oxidation was observed with FSS 441 subjected to dual atmosphere exposures compared with air/air exposures. The TGO layer formed on the 441 exposed to air/air was comprised of Mn-rich, Cr and Fe-containing isomorphic spinel surface crystallites, with a Cr{sub 2}O{sub 3} (eskolaite)-based bottom layer, having a total TGO layer thickness of <2{mu} m after 300 h. In contrast, the TGO layer formed on 441 during dual atmosphere exposure was much faster-growing (>6{mu} m in 20 h) and exhibited a continuous, porous Fe{sub 2}O{sub 3}-rich surface layer with a relatively thin (<2{mu} m) sublayer of similar composition to the TGO layer formed during the air/air exposure. Spontaneous TGO layer spallation was also observed for the air side of 441 exposed to dual atmosphere for >100h. The observed oxidation behavior and TGO layer evolution of 441 in both air/air and dual atmosphere are presented, with possible mechanisms and implications discussed. (author)

Neuromodulators for Functional Gastrointestinal Disorders (Disorders of Gut-Brain Interaction): A Rome Foundation Working Team Report.

2018-03-01

Central neuromodulators (antidepressants, antipsychotics, and other central nervous system-targeted medications) are increasingly used for treatment of functional gastrointestinal disorders (FGIDs), now recognized as disorders of gut-brain interaction. However, the available evidence and guidance for the use of central neuromodulators in these conditions is scanty and incomplete. In this Rome Foundation Working Team report, a multidisciplinary team summarized available research evidence and clinical experience to provide guidance and treatment recommendations. The working team summarized the literature on the pharmacology of central neuromodulators and their effects on gastrointestinal sensorimotor function and conducted an evidence-based review on their use for treating FGID syndromes. Because of the paucity of data for FGIDs, we included data for non-gastrointestinal painful disorders and specific symptoms of pain, nausea, and vomiting. This information was combined into a final document comprising a synthesis of available evidence and recommendations for clinical use guided by the research and clinical experience of the experts on the committee. The evidence-based review on neuromodulators in FGID, restricted by the limited available controlled trials, was integrated with open-label studies and case series, along with the experience of experts to create recommendations using a consensus (Delphi) approach. Due to the diversity of conditions and complexity of treatment options, specific recommendations were generated for different FGIDs. However, some general recommendations include: (1) low to modest dosages of tricyclic antidepressants provide the most convincing evidence of benefit for treating chronic gastrointestinal pain and painful FGIDs and serotonin noradrenergic reuptake inhibitors can also be recommended, though further studies are needed; (2) augmentation, that is, adding a second treatment (adding quetiapine, aripiprazole, buspirone α2δ ligand

Air toxics and the 1990 Clean Air Act: Managing trace element emissions

The US Environmental Protection Agency (EPA) has historically regulated air toxics (hazardous air pollutants) under Section 112 of the Clean Air Act. To date, EPA has established emission standards for 8 hazardous air pollutants (arsenic, asbestos, benzene, beryllium, mercury, radionuclides, coke oven emissions and vinyl chloride). The US electric utility industry was not determined to be a source category requiring regulation for any of the eight chemicals. Of the eight, radionuclides were the last species for which EPA established hazardous emissions standards. In this instance, EPA determined that the risks associated with electric utility fossil fuel power plant emissions were sufficiently low that they should not be regulated. However, the 1990 Clean Air Act Amendments require a new evaluation of the electric utility industry emissions of hazardous air pollutants. This paper summarizes the key features of the air toxics provisions of the Clean Air Act Amendments, describes EPRI's activities on the subject, and provides some preliminary insights from EPRI's research to date

2004-01-01

Building occupants, including cleaning personnel, are exposed to a wide variety of airborne chemicals when cleaning agents and air fresheners are used in buildings. Certain of these chemicals are listed by the state of California as toxic air contaminants (TACs) and a subset of these are regulated...... by the US federal government as hazardous air pollutants (HAPs). California's Proposition 65 list of species recognized as carcinogens or reproductive toxicants also includes constituents of certain cleaning products and air fresheners. In addition, many cleaning agents and air fresheners contain chemicals...... that can react with other air contaminants to yield potentially harmful secondary products. For example, terpenes can react rapidly with ozone in indoor air generating many secondary pollutants, including TACs such as formaldehyde. Furthermore, ozone-terpene reactions produce the hydroxyl radical, which...

Large scale air monitoring: Biological indicators versus air particulate matter

International Nuclear Information System (INIS)

Rossbach, M.; Jayasekera, R.; Kniewald, G.

2000-01-01

Biological indicator organisms are widely used for monitoring and banking purposes since many years. Although the complexity of the interactions between bioorganisms and their environment is generally not easily comprehensible, environmental quality assessment using the bioindicator approach offers some convincing advantages compared to direct analysis of soil, water, or air. Direct measurement of air particulates is restricted to experienced laboratories with access to expensive sampling equipment. Additionally, the amount of material collected generally is just enough for one determination per sampling and no multidimensional characterization might be possible. Further, fluctuations in air masses have a pronounced effect on the results from air filter sampling. Combining the integrating property of bioindicators with the world wide availability and uniform matrix characteristics of air particulates as a prerequisite for global monitoring of air pollution will be discussed. A new approach for sampling urban dust using large volume filtering devices installed in air conditioners of large hotel buildings is assessed. A first experiment was initiated to collect air particulates (300 to 500 g each) from a number of hotels during a period of three to four months by successive vacuum cleaning of used inlet filters from high volume air conditioning installations reflecting average concentrations per three months in different large cities. This approach is expected to be upgraded and applied for global monitoring. Highly positive correlated elements were found in lichen such as K/S, Zn/P, the rare earth elements (REE) and a significant negative correlation between Fig and Cu was observed in these samples. The ratio of concentrations of elements in dust and Usnea spp. is highest for Cr, Zn, and Fe (400-200) and lowest for elements such as Ca, Rb, and Sr (20-10). (author)

Air pollution and urban air quality management in Indonesia

The trade-led industry and economic development after the Asian financial crisis a decade ago has been accelerated in Indonesia to improve the quality of life of its population. This rapid development of Indonesia was in fact heavily fueled by fossil fuels, especially oil, followed by natural gas and coal. The exploitation of fossil fuel in fueling the development resulted in significant environmental quality degradation. Air pollution is perhaps Indonesia's most severe environmental problem. Industry and transportation were the typical main sources of urban air pollutants. Moreover, Indonesia also failed to reach its original 2005 target for a complete phase-out of leaded gasoline. As a result, the level of Pb together with other pollutants such as CO, NO{sub x}, SO{sub 2}, and total suspended particulates has exceeded or at least approached the designated ambient air quality standards. The urban air pollution will not be lesser in extent, but surely will be more severe in the future. Unfortunately, the capability of the Indonesian authorities to manage the urban air quality is still very limited and the portion of the budget allocated to the improvement of urban air quality is still remarkably low, typically 1% of total. This is why the efforts to enhance the capability to manage the urban air quality could not be handled by the environmental authorities in Indonesia's cities themselves, but outside stimulation in the form of man power, consultant and equipment assistance along with financial support has been very important.

1989-01-01

This paper reports two unoccupied bilevel houses of identical design and construction studied to determine the relationships among air exchange, energy consumption, and indoor air quality. The experimental house was retrofitted to increase building tightness and was equipped with an air-to-air heat exchanger; the control house was kept in its initial state of construction. Infiltration, energy, indoor air quality, and environmental parameters were monitored in both houses before and after the retrofit. It was found that the retrofit decreased air infiltration rates by nearly 25 percent, heating energy savings of 12 to 20 percent were achieved through the retrofit, and among the pollutants monitored, only radon and radon progeny increased in proportion to the reduced infiltration. Similarly, when the heat exchanger was operated, radon and radon progeny were the only pollutants reduced in proportion to the added air exchange

The ever increasing level of air pollution in most areas of the world has led to development of a variety of air quality indices for estimation of health effects of air pollution, though the indices have their own limitations such as high levels of subjectivity. Present study, therefore, aimed at developing a novel, fuzzy-based air quality index (FAQI ) to handle such limitations. The index developed by present study is based on fuzzy logic that is considered as one of the most common computational methods of artificial intelligence. In addition to criteria air pollutants (i.e. CO, SO 2, PM 10, O 3, NO 2), benzene, toluene, ethylbenzene, xylene, and 1,3-butadiene were also taken into account in the index proposed, because of their considerable health effects. Different weighting factors were then assigned to each pollutant according to its priority. Trapezoidal membership functions were employed for classifications and the final index consisted of 72 inference rules. To assess the performance of the index, a case study was carried out employing air quality data at five different sampling stations in Tehran, Iran, from January 2008 to December 2009, results of which were then compared to the results obtained from USEPA air quality index (AQI). According to the results from present study, fuzzy-based air quality index is a comprehensive tool for classification of air quality and tends to produce accurate results. Therefore, it can be considered useful, reliable, and suitable for consideration by local authorities in air quality assessment and management schemes. Fuzzy-based air quality index (FAQI).

Air quality management: challenges and solutions in delivering air quality action plans

Energy Technology Data Exchange (ETDEWEB)

2000-07-01

The Air Quality Strategy for England, Scotland, Wales and Northern Ireland (DETR, 2001) has the aim of showing how improved local air quality in the UK may be delivered. Through a process of reviewing and assessing local air quality in both urban and rural localities, a clear picture is emerging of areas of the UK where air quality objectives are not likely to be met. The next challenge will be the identification of the required actions and new ways of working to achieve specific air quality objectives. The declaration of air quality management areas, where objectives are not predicted to be met by their target years, involves co-ordinated local action and collaborative working, which can only be effective with support across local authority departments and external stake holders. This paper provides a background to the relevant legislation underpinning, local air quality management and summarises the review and assessment process. It then comments on future directions in relation to the designation of Air Quality Management Areas and considers the requirements of action plans to deliver the goal of cleaner air in the UK. It is concluded that the UK has developed a highly sophisticated system of air quality management over a relatively short period of time, and with it has brought a new way of local authority working. The challenge of the next stage of the process is likely to be in implementing cost effective and proportional solutions to identified problems at the local level. (Author)

The article discusses the role of EPA's Air and Energy Engineering Research Laboratory (AEERL) in pollution prevention research for cleaner air. For more than 20 years, AEERL has been conducting research to identify control approaches for the pollutants and sources which contribute to air quality problems. The Laboratory has successfully developed and demonstrated cost-effective sulfur dioxide, nitrogen oxides, and particulate control technologies for fossil fuel combustion sources. More recently, it has expanded its research activities to include indoor air quality, radon, organic control, stratospheric ozone depletion, and global warming. AEERL also develops inventories of air emissions of many types. Over the last several years, it has made substantial efforts to expand research on pollution prevention as the preferred choice for air emissions reduction

Feasibility of a solar-assisted winter air-conditioning system using evaporative air-coolers

2011-07-01

The paper presents a winter air-conditioning system which is suitable for regions with mildly cold but dry winters. The system modifies the evaporative air-cooler that is commonly used for summer air-conditioning in such regions by adding a heating process after the humidification process. The paper describes a theoretical model that is used to estimate the system's water and energy consumption. It is shown that a 150-LPD solar heater is adequate for air-conditioning a 500 ft3/min (14.4 m3/min) air flow rate for four hours of operation. The maximum air-flow rate that can be heated by a single solar water-heater for four hours of operation is about 900-cfm, unless a solar water heater large than a 250-LPD heater is used. For the 500 ft3/min air flow rate the paper shows that the 150, 200, 250 and 300 LPD solar water-heaters can provide air-conditioning for 4, 6, 8 and 10 hours, respectively, while consuming less energy than the equivalent refrigerated-type air-conditioner.

Optimization of recirculating laminar air flow in operating room air conditioning systems

Full Text Available The laminar flow air-conditioning system with 100% fresh air is used in almost all operating rooms without discrimination in Turkey. The laminar flow device which is working with 100% fresh air should be absolutely used in Type 1A operating rooms. However, there is not mandatory to use of 100% fresh air for Type 1B defined as places performed simpler operation. Compared with recirculating laminar flow, energy needs of the laminar flow with 100 % fresh air has been emerged about 40% more than re-circulated air flow. Therefore, when a recirculating laminar flow device is operated instead of laminar flow system with 100% fresh air in the Type 1B operating room, annual energy consumption will be reduced. In this study, in an operating room with recirculating laminar flow, optimal conditions have been investigated in order to obtain laminar flow form by analyzing velocity distributions at various supply velocities by using computational fluid dynamics method (CFD.

Full Text Available Beijing has been publishing daily reports on its air quality since 2000, and while the air pollution index (API shows that the air quality has improved greatly since 2000, this is not the perception of Beijing’s residents. The new national ambient air quality standard (NAAQS-2012, which includes the monitoring of PM2.5, has posed stricter standards for evaluating air quality. With the new national standard, the air quality in Beijing is calculated using both NAAQS-2012 and the previous standard. The annual attainment rate has dropped from 75.5% to 50.7%. The spatial analysis of air quality shows that only a background station could attain the national standard, while urban and suburban stations exceed the national standard. Among the six pollutants included in the NAAQS-2012, PM2.5 is the major contributor to the air quality index (AQI comparing with the five other pollutants. The results indicate that under previous NAAQS without PM2.5 monitoring, the air quality has improved greatly in the past decade.  By considering PM2.5, the air quality attainment has dropped greatly. Furthermore, a great effort is needed for local government to bring down the PM2.5 concentration.

The purpose of this paper is to reveal both the psychosomatic and the physical effects of local air velocity from an air conditioner using biomarkers which can be collected noninvasively. Salivary {alpha}-amylase activity (SAA) and salivary cortisol were used as the indexes of psychosomatic effects. The total protein (TP) collected from stratum corneum was used as an index of the physical condition of dry skin. A continuous experiment over a 5 days period in summer was conducted using 8 healthy young male adults for 2-types of airflow conditioners, a whole ceiling-type air conditioner (without local air velocity) and a normal-type air conditioner (with local air velocity). The subjects felt cool, windy, dry and uncomfortable when under the normal-type air conditioner as determined in a subjective evaluation. The SAA under the normal-type air conditioner fluctuated more widely than with the whole ceiling-type air conditioner. The level of salivary cortisol decreased more in a day under the normal-type air conditioner than with the whole ceiling-type air conditioner. These results showed that reducing local air velocity may provide more healthy psychosomatic conditions over the long-term. Moreover, the TP of a drying-exposed skin area showed a significant change during this experiment whereas the TP of drying-protected area was relatively unchanged. It was indicated that one week's exposure to local air velocity conditions possibly influences the drying of facial skin. Thus, air movement at low velocity can be provides more comfortable conditions not only psychosomatically but also physically. (author)

Air lasing

CERN Document Server

Cheng, Ya

2018-01-01

This book presents the first comprehensive, interdisciplinary review of the rapidly developing field of air lasing. In most applications of lasers, such as cutting and engraving, the laser source is brought to the point of service where the laser beam is needed to perform its function. However, in some important applications such as remote atmospheric sensing, placing the laser at a convenient location is not an option. Current sensing schemes rely on the detection of weak backscattering of ground-based, forward-propagating optical probes, and possess limited sensitivity. The concept of air lasing (or atmospheric lasing) relies on the idea that the constituents of the air itself can be used as an active laser medium, creating a backward-propagating, impulsive, laser-like radiation emanating from a remote location in the atmosphere. This book provides important insights into the current state of development of air lasing and its applications.

Microfluidic liquid-air dual-gradient chip for synergic effect bio-evaluation of air pollutant.

In this paper, a novel prototype liquid-air dual gradient chip is introduced, which has paved the way for effective synergic effect bio-evaluation of air pollutant. The chip is composed of an array of the agarose liquid-air interfaces, top air gradient layer and bottom liquid gradient layer. The novel agarose liquid-air interface allows for non-biased exposure of cells to all the substances in the air and diffusive interactions with the liquid phase; while the dual liquid-air gradient provides powerful screening abilities, which well reduced errors, saved time and cost from repeated experiment. Coupling the two functions, the chip subsequently facilitates synergic effect evaluation of both liquid and air factors on cells. Here cigarette smoke was taken as the model air pollutant, and its strong synergic effects with inflammatory level of A549 lung cancer cells on their fate were successfully quantified for the first time. These results well testified that the proposed dual-gradient chip is powerful and indispensable for bio-evaluation of air pollutant. Copyright © 2018 Elsevier B.V. All rights reserved.

Long-term Changes in Extreme Air Pollution Meteorology and the Implications for Air Quality.

Science.gov (United States)

Hou, Pei; Wu, Shiliang

2016-03-31

Extreme air pollution meteorological events, such as heat waves, temperature inversions and atmospheric stagnation episodes, can significantly affect air quality. Based on observational data, we have analyzed the long-term evolution of extreme air pollution meteorology on the global scale and their potential impacts on air quality, especially the high pollution episodes. We have identified significant increasing trends for the occurrences of extreme air pollution meteorological events in the past six decades, especially over the continental regions. Statistical analysis combining air quality data and meteorological data further indicates strong sensitivities of air quality (including both average air pollutant concentrations and high pollution episodes) to extreme meteorological events. For example, we find that in the United States the probability of severe ozone pollution when there are heat waves could be up to seven times of the average probability during summertime, while temperature inversions in wintertime could enhance the probability of severe particulate matter pollution by more than a factor of two. We have also identified significant seasonal and spatial variations in the sensitivity of air quality to extreme air pollution meteorology.

Air Leakage and Air Transfer Between Garage and Living Space

2014-09-01

This research project focused on evaluation of air transfer between the garage and living space in a single-family detached home constructed by a production homebuilder in compliance with the 2009 International Residential Code and the 2009 International Energy Conservation Code. The project gathered important information about the performance of whole-building ventilation systems and garage ventilation systems as they relate to minimizing flow of contaminated air from garage to living space. A series of 25 multi-point fan pressurization tests and additional zone pressure diagnostic testing characterized the garage and house air leakage, the garage-to-house air leakage, and garage and house pressure relationships to each other and to outdoors using automated fan pressurization and pressure monitoring techniques. While the relative characteristics of this house may not represent the entire population of new construction configurations and air tightness levels (house and garage) throughout the country, the technical approach was conservative and should reasonably extend the usefulness of the results to a large spectrum of house configurations from this set of parametric tests in this one house. Based on the results of this testing, the two-step garage-to-house air leakage test protocol described above is recommended where whole-house exhaust ventilation is employed.

In Japan, biological safety cabinets (BSCs) are normally used by medical staff while handling antineoplastic agents. We have also set up a class II B2 BSC at the Division of Chemotherapy for Outpatients. The air temperature inside this BSC, however, decreases in winter. We assumed that this decrease is caused by the intake of open-air. Therefore, we investigated the effects of low open-air temperature on the BSC temperature and the time of admixtures of antineoplastic agents. The studies were conducted from January 1 to March 31, 2008. The outdoor air temperature was measured in the shade near the intake nozzle of the BSC and was compared with the BSC temperature. The correlation between the outdoor air temperature and the BSC temperature, the dissolution time of cyclophosphamide (CPA) and gemcitabine (GEM), and accurate weight measurement of epirubicin (EPI) solution were investigated for low and normal BSC temperatures. The BSC temperature was correlated with the open-air temperature for open-air temperatures of 5-20°C (p air is drawn from outdoors. We showed that the BSC temperature affects the dissolution rate of antineoplastic agents. Further, we suggested that the BSC temperature drop might delay the affair of the admixtures of antineoplastic agents and increase the waiting time of outpatients for chemotherapy.

Highlights: • A numerical study of desiccant air conditioning systems is presented. • The ε-NTU model is used for the analysis. • Different arrangements of the desiccant systems were compared. • The systems were compared under different operating conditions. - Abstract: This paper presents a numerical analysis of three desiccant air-conditioning systems equipped with different indirect evaporative air coolers: (1) the cross-flow Maisotsenko cycle heat and mass exchanger (HMX), (2) the regenerative counter-flow Maisotsenko cycle heat and mass exchanger and (3) the standard cross-flow evaporative air cooler. To analyze the desiccant wheel and the indirect evaporative air coolers, the modified ε-NTU-model was used. The simulations were performed under assumption that the desiccant wheel is regenerated with air heated to relatively low temperature values (50–60 °C), which can be produced with solar panels in typical moderate climatic conditions. It was established that the main advantage of the presented solutions is that they can provide comfort conditions even with less effective dehumidification. The different systems were compared under variable selected operational factors (i.e. inlet air temperature, humidity and regeneration air temperature). The analysis allowed establishing the advantages and disadvantages of presented solutions and allowed estimating their application potential.

A critical aspect of air pollution exposure assessments is estimation of the air exchange rate (AER) for various buildings where people spend their time. The AER, which is the rate of exchange of indoor air with outdoor air, is an important determinant for entry of outdoor air pollutants and for removal of indoor-emitted air pollutants. This paper presents an overview and critical analysis of the scientific literature on empirical and physically based AER models for residential and commercial buildings; the models highlighted here are feasible for exposure assessments as extensive inputs are not required. Models are included for the three types of airflows that can occur across building envelopes: leakage, natural ventilation, and mechanical ventilation. Guidance is provided to select the preferable AER model based on available data, desired temporal resolution, types of airflows, and types of buildings included in the exposure assessment. For exposure assessments with some limited building leakage or AER measurements, strategies are described to reduce AER model uncertainty. This review will facilitate the selection of AER models in support of air pollution exposure assessments.

The effect of facially applied air movement on perceived air quality (PAQ) at high humidity was studied. Thirty subjects (21 males and 9 females) participated in three, 3-h experiments performed in a climate chamber. The experimental conditions covered three combinations of relative humidity and local air velocity under a constant air temperature of 26 C, namely: 70% relative humidity without air movement, 30% relative humidity without air movement and 70% relative humidity with air movement under isothermal conditions. Personalized ventilation was used to supply room air from the front toward the upper part of the body (upper chest, head). The subjects could control the flow rate (velocity) of the supplied air in the vicinity of their bodies. The results indicate an airflow with elevated velocity applied to the face significantly improves the acceptability of the air quality at the room air temperature of 26 C and relative humidity of 70%.

This report provides technical information on air sampling that will be useful for facilities following the recommendations in the NRC's Regulatory Guide 8.25, Revision 1, ''Air sampling in the Workplace.'' That guide addresses air sampling to meet the requirements in NRC's regulations on radiation protection, 10 CFR Part 20. This report describes how to determine the need for air sampling based on the amount of material in process modified by the type of material, release potential, and confinement of the material. The purposes of air sampling and how the purposes affect the types of air sampling provided are discussed. The report discusses how to locate air samplers to accurately determine the concentrations of airborne radioactive materials that workers will be exposed to. The need for and the methods of performing airflow pattern studies to improve the accuracy of air sampling results are included. The report presents and gives examples of several techniques that can be used to evaluate whether the airborne concentrations of material are representative of the air inhaled by workers. Methods to adjust derived air concentrations for particle size are described. Methods to calibrate for volume of air sampled and estimate the uncertainty in the volume of air sampled are described. Statistical tests for determining minimum detectable concentrations are presented. How to perform an annual evaluation of the adequacy of the air sampling is also discussed

The Atmospheric Infrared Sounder (AIRS) on NASA's Aqua spacecraft has been returning daily global observations of Earth's atmospheric constituents and properties since 2002. With a 12-year data record and daily, global observations in near real-time, AIRS data can play a role in applications that fall under many of the NASA Applied Sciences focus areas. For vector-borne disease, research is underway using AIRS near surface retrievals to assess outbreak risk, mosquito incubation periods and epidemic potential for dengue fever, malaria, and West Nile virus. For drought applications, AIRS temperature and humidity data are being used in the development of new drought indicators and improvement in the understanding of drought development. For volcanic hazards, new algorithms using AIRS data are in development to improve the reporting of sulfur dioxide concentration, the burden and height of volcanic ash and dust, all of which pose a safety threat to aircraft. In addition, anomaly maps of many of AIRS standard products are being produced to help highlight "hot spots" and illustrate trends. To distribute it's applications imagery, AIRS is leveraging existing NASA data frameworks and organizations to facilitate archiving, distribution and participation in the BEDI. This poster will communicate the status of the applications effort for the AIRS Project and provide examples of new maps designed to best communicate the AIRS data.

Significance of air humidity and air velocity for fungal spore release into the air

Science.gov (United States)

Pasanen, A.-L.; Pasanen, P.; Jantunen, M. J.; Kalliokoski, P.

Our previous field studies have shown that the presence of molds in buildings does not necessarily mean elevated airborne spore counts. Therefore, we investigated the release of fungal spores from cultures of Aspergillus fumigatus, Penicillium sp. and Cladosporium sp. at different air velocities and air humidities. Spores of A. fumigatus and Penicillium sp. were released from conidiophores already at air velocity of 0.5 ms -1, whereas Cladosporium spores required at least a velocity of 1.0 ms -1. Airborne spore counts of A. fumigatus and Penicillium sp. were usually higher in dry than moist air, being minimal at relative humidities (r.h.) above 70%, while the effect of r.h. on the release of Cladosporium sp. was ambivalent. The geometric mean diameter of released spores increased when the r.h. exceeded a certain level which depends on fungal genus. Thus, spores of all three fungi were hygroscopic but the hygroscopicity of various spores appeared at different r.h.-ranges. This study indicates that spore release is controlled by external factors and depends on fungal genus which can be one reason for considerable variation of airborne spore counts in buildings with mold problems.

Because of better comfort, air conditioning systems are a common feature in automobiles these days. However, its impact on the number of particles and microorganisms inside the vehicle--and by this its impact on the risk of an allergic reaction--is yet unknown. Over a time period of 30 months, the quality of air was investigated in three different types of cars (VW Passat, VW Polo FSI, Seat Alhambra) that were all equipped with a automatic air conditioning system. Operation modes using fresh air from outside the car as well as circulating air from inside the car were examined. The total number of microorganisms and the number of mold spores were measured by impaction in a high flow air sampler. Particles of 0.5 to 5.0 microm diameter were counted by a laser particle counter device. Overall 32 occasions of sampling were performed. The concentration of microorganisms outside the cars was always higher than it was inside the cars. Few minutes after starting the air conditioning system the total number of microorganisms was reduced by 81.7%, the number of mold spores was reduced by 83.3%, and the number of particles was reduced by 87.8%. There were no significant differences neither between the types of cars nor between the types of operation mode of the air conditioning system (fresh air vs. circulating air). All parameters that were looked for in this study improved during utilization of the car's air conditioning system. We believe that the risk of an allergic reaction will be reduced during use also. Nevertheless, we recommend regular maintenance of the system and replacement of older filters after defined changing intervals.

Kinetics of NO formation and decay in nanosecond pulse discharges in Air, H2-Air, and C2H4-Air mixtures

International Nuclear Information System (INIS)

Burnette, David; Shkurenkov, Ivan; Adamovich, Igor V; Lempert, Walter R

Time-resolved, absolute NO and N atom number densities are measured by NO Laser Induced Fluorescence (LIF) and N Two-Photon Absorption LIF in a diffuse plasma filament, nanosecond pulse discharge in dry air, hydrogen-air, and ethylene-air mixtures at 40 Torr, over a wide range of equivalence ratios. The results are compared with kinetic modeling calculations incorporating pulsed discharge dynamics, kinetics of vibrationally and electronically excited states of nitrogen, plasma chemical reactions, and radial transport. The results show that in air afterglow, NO decay occurs primarily by the reaction with N atoms, NO  +  N  →  N 2   +  O. In the presence of hydrogen, this reaction is mitigated by reaction of N atoms with OH, N  +  OH  →  NO  +  H, resulting in significant reduction of N atom number density in the afterglow, additional NO production, and considerably higher NO number densities. In fuel-lean ethylene-air mixtures, a similar trend (i.e. N atom concentration reduction and NO number density increase) is observed, although [NO] increase on ms time scale is not as pronounced as in H 2 -air mixtures. In near-stoichiometric and fuel-lean ethylene-air mixtures, when N atom number density was below detection limit, NO concentration was measured to be lower than in air plasma. These results suggest that NO kinetics in hydrocarbon-air plasmas is more complex compared to air and hydrogen-air plasmas, additional NO reaction pathways may well be possible, and their analysis requires further kinetic modeling calculations.

Full Text Available Backgound and Objectives: Individuals living in cities increasingly spend more time indoors in air-conditioned environments. Air conditioner contamination can be caused by the presence of aerosols from the external or internal environment, which may be associated with disease manifestations in patients present in this type of environment. Therefore, the aim of this review was to assess the air quality in air-conditioned hospital environments as a risk factor for hospital-acquired infections – HAI – as the air can be a potential source of infection, as well as assess the exposure of professionals and patients to different pollutants. Material and Methods: A literature review was performed in the LILACS, MEDLINE, SCIELO, SCIENCE DIRECT databases, CAPES thesis database and Ministry of Health – Brazil, including studies published between 1982 and 2008. The literature search was grouped according to the thematic focus, as follows: ventilation, maintenance and cleaning of systems that comprehend the environmental quality standard. Discussion and Conclusion: Outbreaks of hospital-acquired infections associated with Aspergillus, Acinetobacter, Legionella, and other genera such as Clostridium and Nocardia, which were found in air conditioners, were observed, thus indicating the need for air-conditioning quality control in these environments.

Air pollution control in India

International Nuclear Information System (INIS)

Jain, S.K.

1995-01-01

Prior to rapid spurt in industrialization in India, people were used to inhale pure air containing about 78% nitrogen, 21% oxygen and some carbon dioxide. But afterwards this composition of pure air was disturbed as a result of increased economic activities. Air, now a days also contains sulphur dioxide, carbon monoxide, nitrogen oxides etc., etc. which are extremely harmful for human health. Virulence of air pollution was realised in late eighties after Bhopal Gas Tragedy (BGT) and an effective air quality management started taking shape in India afterwards. The basic components of air quality management are legislation and regulations, emission inventory, air quality standards and monitoring, air dispersion models and installation of pollution control equipment which are being discussed in this paper.

Technology Candidates for Air-to-Air and Air-to-Ground Data Exchange is a two-year research effort to visualize the U. S. aviation industry at a point 50 years in the future, and to define potential communication solutions to meet those future data exchange needs. The research team, led by XCELAR, was tasked with identifying future National Airspace System (NAS) scenarios, determining requirements and functions (including gaps), investigating technical and business issues for air, ground, & air-to-ground interactions, and reporting on the results. The project was conducted under technical direction from NASA and in collaboration with XCELAR's partner, National Institute of Aerospace, and NASA technical representatives. Parallel efforts were initiated to define the information exchange functional needs of the future NAS, and specific communication link technologies to potentially serve those needs. Those efforts converged with the mapping of each identified future NAS function to potential enabling communication solutions; those solutions were then compared with, and ranked relative to, each other on a technical basis in a structured analysis process. The technical solutions emerging from that process were then assessed from a business case perspective to determine their viability from a real-world adoption and deployment standpoint. The results of that analysis produced a proposed set of future solutions and most promising candidate technologies. Gap analyses were conducted at two points in the process, the first examining technical factors, and the second as part of the business case analysis. In each case, no gaps or unmet needs were identified in applying the solutions evaluated to the requirements identified. The future communication solutions identified in the research comprise both specific link technologies and two enabling technologies that apply to most or all specific links. As a result, the research resulted in a new analysis approach, viewing the

Air Pollution and Stroke.

2018-01-01

The adverse health effects of air pollution have long been recognised; however, there is less awareness that the majority of the morbidity and mortality caused by air pollution is due to its effects on the cardiovascular system. Evidence from epidemiological studies have demonstrated a strong association between air pollution and cardiovascular diseases including stroke. Although the relative risk is small at an individual level, the ubiquitous nature of exposure to air pollution means that the absolute risk at a population level is on a par with "traditional" risk factors for cardiovascular disease. Of particular concern are findings that the strength of this association is stronger in low and middle income countries where air pollution is projected to rise as a result of rapid industrialisation. The underlying biological mechanisms through which air pollutants exert their effect on the vasculature are still an area of intense discussion. A greater understanding of the effect size and mechanisms is necessary to develop effective strategies at individual and policy levels to mitigate the adverse cardiovascular effects of air pollution.

Optimizing the Air Dissolution Parameters in an Unpacked Dissolved Air Flotation System

Directory of Open Access Journals (Sweden)

Adam Dassey

2011-12-01

Full Text Available Due to the various parameters that influence air solubility and microbubble production in dissolved air flotation (DAF, a multitude of values that cover a large range for these parameters are suggested for field systems. An unpacked saturator and an air quantification unit were designed to specify the effects of power, pressure, temperature, hydraulic retention time, and air flow on the DAF performance. It was determined that a pressure of 621 kPa, hydraulic retention time of 18.2 min, and air flow of 8.5 L/h would be the best controlled parameters for maximum efficiency in this unit. A temperature of 7 °C showed the greatest microbubble production, but temperature control would not be expected in actual application. The maximum microbubble flow from the designed system produced 30 mL of air (±1.5 per L of water under these conditions with immediate startup. The maximum theoretical dissolved air volume of 107 mL (±6 was achieved at a retention time of 2 h and a pressure of 621 kPa. To isolate and have better control over the various DAF operational parameters, the DAF unit was operated without the unsaturated flow stream. This mode of operation led to the formation of large bubbles at peak bubble production rates. In a real-world application, the large bubble formation will be avoided by mixing with raw unsaturated stream and by altering the location of dissolved air output flow.

Interactions between particulate air pollution and temperature in air pollution mortality time series studies

International Nuclear Information System (INIS)

Roberts, Steven

2004-01-01

In many community time series studies on the effect of particulate air pollution on mortality, particulate air pollution is modeled additively. In this study, we investigated the interaction between daily particulate air pollution and daily mean temperature in Cook County, Illinois and Allegheny County, Pennsylvania, using data for the period 1987-1994. This was done through the use of joint particulate air pollution-temperature response surfaces and by stratifying the effect of particulate air pollution on mortality by temperature. Evidence that the effect of particulate air pollution on mortality may depend on temperature is found. However, the results were sensitive to the number of degrees of freedom used in the confounder adjustments, the particulate air pollution exposure measure, and how the effects of temperature on mortality are modeled. The results were less sensitive to the estimation method used--generalized linear models and natural cubic splines or generalized additive models and smoothing splines. The results of this study suggest that in community particulate air pollution mortality time series studies the possibility of an interaction between daily particulate air pollution and daily mean temperature should be considered

Perception of cabin air quality in airline crew related to air humidification, on intercontinental flights.

Science.gov (United States)

Lindgren, T; Norbäck, D; Wieslander, G

2007-06-01

The influence of air humidification in aircraft, on perception of cabin air quality among airline crew (N = 71) was investigated. In-flight investigations were performed in the forward part and in the aft part on eight intercontinental flights with one Boeing 767 individually, equipped with an evaporation humidifier combined with a dehumidifying unit, to reduce accumulation of condensed water in the wall construction. Four flights had the air humidification active when going out, and turned off on the return flight. The four others had the inverse humidification sequence. The sequences were randomized, and double blind. Air humidification increased relative air humidity (RH) by 10% in forward part, and by 3% in aft part of the cabin and in the cockpit. When the humidification device was active, the cabin air was perceived as being less dry (P = 0.008), and fresher (P = 0.002). The mean concentration of viable bacteria (77-108 cfu/m(3)), viable molds (74-84 cfu/m(3)), and respirable particles (1-8 microg/m3) was low, both during humidified and non-humidified flights. On flights with air humidification, there were less particles in the forward part of the aircraft (P = 0.01). In conclusion, RH can be slightly increased by using ceramic evaporation humidifier, without any measurable increase of microorganisms in cabin air. The cabin air quality was perceived as being better with air humidification. PRACTICAL IMPLICATION: Relative air humidity is low (10-20%) during intercontinental flights, and can be increased by using ceramic evaporation humidifier, without any measurable increase of microorganism in cabin air.

Full Text Available In Sweden, the dam-safety guidelines call for an overhaul of many existing bottom outlets. During the opening of an outlet gate, understanding the transient air-water flow is essential for its safe operation, especially under submerged tailwater conditions. Three-dimensional CFD simulations are undertaken to examine air-water flow behaviors at both free and submerged outflows. The gate, hoisted by wire ropes and powered by AC, opens at a constant speed. A mesh is adapted to follow the gate movement. At the free outflow, the CFD simulations and model tests agree well in terms of outlet discharge capacity. Larger air vents lead to more air supply; the increment becomes, however, limited if the vent area is larger than 10 m2. At the submerged outflow, a hydraulic jump builds up in the conduit when the gate reaches approximately 45% of its full opening. The discharge is affected by the tailwater and slightly by the flow with the hydraulic jump. The flow features strong turbulent mixing of air and water, with build-up and break-up of air pockets and collisions of defragmented water bodies. The air demand rate is several times as much as required by steady-state hydraulic jump with free surface.
