breakadoninak.ml/map13.php Carcinogens differ somewhat from other toxins for two very important reasons. First, very small amounts of material can cause a carcinogenic effect. Second, the effects of exposure may not appear for years. Theoretically, one molecule can cause cancer called the one-molecule - one-hit theory although cancer is much more likely after substantial, repeated exposures.
Whenever a known or suspected carcinogen is involved, responders must use the highest levels of appropriate protection. Examples of carcinogens are coal tar, asbestos, vinyl chloride, and benzene. These changes can be inherited by offspring. Changes in the genetic sequence can alter the genetic code. These genetic changes can have numerous effects including the failure of important biochemical processes.
In some cases they can also cause cancer. Some known human mutagenic toxins are ethylene oxide, ionizing radiation, hydrogen peroxide, ethylene dibromide, and benzene. Esos cambios pueden heredarlos los hijos. Pregnant women must be very careful about the types of exposures they encounter. One of the most notorious teratogens is thalidomide, a drug used in the mids. This chemical was a treatment for morning sickness. It caused thousands of cases of phocomelia and amelia before being taken off the market.
Indeed, some substances, including fat soluble toxins, are readily passed to the infant, where they are trapped and accumulate in the womb. Some other agents known to be teratogenic in humans are anesthetic gases, organic mercury compounds, and ionizing radiation. Las mujeres embarazadas deben tener mucho cuidado sobre los tipos de exposiciones que puedan encontrar. Acute is a one-time, limited, or short-term exposure. Whereas, chronic is continuous, repeated, or long-term exposure. Slide title: Types of Effects Tipos de efectos Text: The same two terms are used when speaking of effects of chemicals on the body.
Acute effects range from immediate effects to death within minutes. Other acute effects could cause complications to the central nervous system. Chronic effects may not be detectable for years. They also may cause death, illness, or central nervous system damage.
There are a number of variables in toxicology that may affect reactions to an exposure. Those variables include the type of chemical or toxin, the dose or concentration, the duration and frequency of the exposure, and personal tolerances. Personal tolerances can be affected by age, sex, size, health, other toxins, and built up resistance or immunity from repeated exposure.
Slide title: Reversible and Irreversible Reversible e irreversible Text: Reversible effects are the types of reactions that generally refer to the ability of an injured tissue to repair itself. An example of a reversible effect would be a reaction from exposure to compounds that injure the liver, or cause changes in liver function during the time of exposure that are lessened once the exposure to the compound has been terminated.
At that point, the function of the liver is able to return to normal. Irreversible effects reflect organs that do not have this capability. Such an organ system would be the central nervous system. In this organ system, most toxic damage is generally irreversible. Los efectos reversibles son los tipos de reacciones que generalmente se refieren a la capacidad que tiene un tejido lesionado de curarse solo.
Systemic toxicity requires the distribution of a toxin away from its entry point. Systemic toxicity causes a response at a distant site from the point of absorption. Absorption - toxins can be absorbed into the body through the skin and through mucous membrane such as the eyes. Ingestion - toxins can also be ingested into our system. An example would be medicines that we take orally. Injection - finally, toxins can be injected into our bodies. Knowing the route of entry of toxins into our body will allow us to prevent exposure. A poison in small amounts can produce injury or death to susceptible tissues.
Having an overview of toxicology and the routes of entry of toxins into our body will allow us to prevent exposure whenever we work around these products. Debido a las reiteradas salidas de servicio ocurridas en un sector tan acotado de su traza, ubicado sobre Av. Se obtuvieron las siguientes curvas: Fig. La Fig. Se realizaron sondeos sobre el eje de las ternas a los efectos de definir el sector de la traza en el cual los cables se encuentran instalados en suelo arenoso y de escasa humedad.
Carga de la segunda terna: A. Se muestran en la Fig. Temperatura Exterior del Cable. Registros de Carga [Amper]. En la Fig. Registro de Temperaturas. La frecuencia necesaria para realizar las mediciones depende del estado de carga y temperatura de los cables.
Se presenta en la Fig. Observando la Fig. Translation - English Overview — The purpose of this paper is to explain the performance of works on an existing dual system of kV three-phase line of cables laid underground which has enabled to troubleshoot repeated breakdowns caused by temperature overheating, thus restoring them to its original power.
It contains the measuring method used, the notional survey performed from those measurements, and the outcome analysis that has resulted. Then it describes all civil works performed to restore installation reliability. Finally it introduces the approach that has been used for cable operation monitoring.
Keywords: Themal resistivity; temperature; thermal measurement; electric power transmission capacity. The repeated breakdowns occurred over such a brief portion of the cable route located on Rafael Obligado Ave. As a result the following curve graphs have been acquired: Figure 1: First Failure. As a conclusion from the graphic information shown above, in all three events, the 3-phase line had been operating continuously to the limit of its electric power transmission capacity, A MVA , during 24 hours prior to each of the outages.
All along this period, the other 3-phase line load, located at 0.
According to the information reported by the crew in charge of cable repairs, the area was on a gritty and totally barren ground under high temperature conditions. Heat dissipation is being put at stake because of the high thermal resistivity typical of those ground features. Heat input from cables causes greater ground dryness, thus increasing ground thermal resistivity. For this reason, temperature is being increased even further, therefore reducing humidity even more. Should the heat flow caused by cables goes beyond measure, the conditions will miss the right thermal balance causing a cascade effect.
This has been the case after the 24 hour operation to the limit of its capacity. In addition, a sensor for measuring temperature was installed on every location in contact with the outer cable jacketing for measuring out the ground heat dissipation capability on each location. Following there is a detailed observation from those probings: Measuring Point 1: It is located between 2 failure positions on the cable.
Ground encountered is composed of a totally dried very thin sand layer. Measuring Point 2: It is located at a meter NW-oriented distance from previous position. Ground encountered results in a totally wet sand layer. Measuring Point 3: Probing performed at a 1, meter SE-oriented distance from the original position. Ground encountered results in reddish-brown soil of little humidity. Measuring Point 4: It is performed at a meter SE-oriented from the original position. Ground encountered is sandy, humid with presence of oyster-shell mixtures.
Following observations in the excavations performed, it was determined that the portion of cable route with potential risk to future failures was being delimited by points Performing measurements after a three day period was necessary to gain some stable temperature level after covering the probes.
For that reason thermal analysis was performed by measuring temperatures on this location. Figure 4 shows temperature values from the outer cable jacketing measured from am to am on the next day: Figure 4. Outer Cable Temperature In order to obtain the ratio between the electrical three-phase lines load status and the temperature values measured, three-phase lines loads were recorded all along the same time of the day. Figure 5 shows those records. Figure 5. Load Records [Ampere]. Input of current values from the three-phase lines on an hourly basis and then assuming soil thermal resistivity values allows to obtain outer cable jacketing temperatures.
Soil thermal resistivity survey was possible by aproaching a measured temperature curve to a temperature based on a preset value. Figure 6. The resulting thermal resistivity accounts for the cable high temperature values, therefore occurring the subsequent failures after 24 hour continuous operation at maximum load. That is the reason why so many repeated failures have occurred in that portion of the cable route. After discovering root causes for cable overheating, it has become necessary to find the way to retoring soil features and optimizing heat dissipation capability of all three-phase lines, the purpose of which is to return the installation power to normal.
With this in view, a PVC tube has been fitted as shown on Figures The tubing has been used to feed in water in order to wet the ground and improve soil thermal resistivity coefficient. Along different portions and directly on the cable more thermocouples have been added to measure temperature and evaluate whether the results have been proper enough. Figure 7. Installation of tubing to feed in water Figure 8. Additionally, feeding of water was possible through plugs situated every 20 meters. This way the even distribution of humidity on the ground was achieved all along the cable route, avoiding possible timely overheating events.
The proper location of sensors was in between the closest existing plugs with the aim to measure temperature at the furthest point possible from the feed-in points.
After the excavation and installation of tubes, all tubing was buried under ordinary earth instead of the already removed sand. As the various lengths of tubing were completed, feeding of water and measuring the temperature through the fitted thermocouples started. This was necessary because the affected area of the installation was 1, meters long, and an alternative solution would become essential, should the expected results were not feasible. Figure 9 shows qualitative temperature record curves for some of the sensors installed.
In addittion to reducing temperature, values among every location became standarized. Figure 9. In such a case, the early detection of a new injection of water is significant taking into account both load and temperature present in cables. After feeding in all water plugs, the ground humidity contents was such that the normal operation of all three-phase lines was possible. A weekly measurement frequency could be performed under this condition whenever a A average current was not exceeded.
When a higher load status became necessary, a more frequent monitoring became essential to check that temperatures would be kept within the expected values, i.
Figure 10 shows the expected temperature values for the three-phase line under survey based on the load record from both three-phase lines. Assuming the more proper curve depending on the current flow on that three-phase line and according to the current flow through the three-phase line under survey, it is possible to know the temperature for normal operation. It is important to state that these curves result from the cable operating temperatures under balanced, continuous and simultaneous conditions. Accordingly, in the case of cables with low load values, dryness of the soil should not be assumed whenever the temperature measured is a bit higher than the temperature shown in the graph.
That may be the case when thermal inertia in the installation is present, i. On the contrary, in the case of three-phase lines with high load values, whenever the measured temperature is closer to the temperature shown in the graph, it does not necessarily mean that the condition is normal since it might be that the expected balance has not been reached yet. Figure According to the explanation above, high load values present in three-phase lines mean a higher measurement frequency.
Daily measurements were necessary, especially performed at maximum load hours A or more. And like a summary, the policy based on the recorded values has been translated into graphical information on a chart. Figure 11 shows the graph curve to be followed regarding the actions that should be implemented based on the load values and the recorded temperatures, assuming a A value for the second three-phase line.
Similar curve graphs have been acquired for the different current values present in the same three-phase line. The closest value to the actual average value should be the one to be used. Primary measurements from each sensor show higher values, then coming to lower values as soon as the water injection begins. This is the baseline used to estimate the cable original thermal value. Should the ground humidity level is being achieved, that will be the expected temperature in all cables.

The recurrence of abstract motifs within the rock art of this area, and its durability over time, could be an indication of common cultural patterns among the different populations that inhabited the province.
We think that we are able to approach, in a scientific way, the ritual and symbolic aspects of those who elaborated these paintings. In this book, the author proposes an alternative according to the theoretical framework of disciplines such as ethnography, anthropology, landscape archaeology, archaeoastronomy and semiotics. She has participated in vari. This publication presents the defense of the city of Valencia during the years under two premises; whether Valencia was strategically bombed and which were the targets. The second premise is whether the city was efficiently organized to protect its civilians.
The methodological proposal is based on the use of the classical parameters of the archaeological intervention, with the possibility of elaborating catalogs of goods, thematic, temporary, etc. Those derived in tools for urban planning, archaeological charts, and other documents. It also carries out a comparative analysis of the current legislative framework at national and regional level Murcia, Valencia and Catalonia. A classification is made of the elements that make up the different heritages and their main characteristics. All this is done through extensive prospecting and GPS, with planimetric surveys of the localized remains and the digitalization of the entire planimetry of the time.
A planimetric map of all shelters in the city is elaborated and the village of Puig. Moreover, a glossary of military terminology is added with the purpose of helping the reader, in addition to a daily list of the bombings that the city suffered during the years to Spanish text with extended English summary. Available both in printed and e-versions. Also, its location meant that, from the middle of the 6th Century, it was directly affected by some of the most relevant historical episodes of those times: the foundation of the royal city of Reccopoli, the establishment of the Servitanus monastery, the transformation of Toledo as the metropolitan seat of the Carthaginian province and the military campaigns against the imperial forces.
Parallel to this, archaeological excavations document a process of disrupting the old urban centres in favour of small populations within their municipal territory. In this way, the ancient Roman cities were reduced to serve as a symbolic reference of the small villages that developed in the shadow of the old urban centres. This volume presents a historical and archaeological study of the province of Cuenca in Late Antiquity. The study concludes with an examination of the archaeological collection from the province, which has been divided into three large groups: monumental sculpture and epigraphic items, ceramic productions and metalwork arts.
The first group is mainly constituted by the findings made in the excavations of Cabeza de Griego Segobriga. Most of the pottery productions correspond to vessels placed as funerary deposits. Due to the absence of excavations, the ceramics for kitchen and storage use are hardly represented, whereas there is an overrepresentation of types destined for use as libations or offerings. Finally, most of the elements of industrial arts correspond to elements of the Latin-Mediterranean fashion or Byzantine style of the 7th Century.
The almost total absence of materials corresponding to the Pontic-Danubian fashion also should be noted. The research focusses on the archaeological and paleopathological remains of the religious population.

The archaeological excavations were supported with the existing archival material, and enabled the first assessment of Jerez society to be carried out, including a whole series of elements that have not been studied thus far, such as the causes of death and disease suffered by the people of the city. To this end, a study was carried out examining the pathologies found in the skeletal remains housed at the municipal archaeological museum of Jerez de la Frontera, which originated mainly from epidemic burials.
Etnicidad vs. Una mirada desde la meseta sur by Rafael Barroso Cabrera. Spanish text with English summary. The Visigoth settlement in the Iberian Peninsula and its relationship with the archaeological record of the 5th-6th centuries AD continues to be one of the most controversial issues in Spanish archaeology. The purely archaeological aspect of the controversy relates to an archaeological interpretation, stemming from the ranks of the so-called New Archeology, of the Castilian necropoleis containing grave goods of Pontic-Danubian type. This interpretation places special emphasis on social and cultural phenomena above the ethnic criteria defended by the Vienna School.
This volume approaches the ideological question that underlies these controversies, as well as their repercussions in the direction adopted by later archaeological investigations in relation to the history of Spain. At the same time, it relativizes the role played by the Visigoth period in the Francoist ideological construction.
Once the discussion is framed in these terms, the author dedicates his study to a refutation of the cultural interpretation of the phenomenon of the Visigothic necropoleis of the Castilian plateau based on the archaeological data and by comparing this data with literary sources.
The study also addresses two other historical problems that could be related to the Gothic settlement in the Castilian plateau: the creation of the bishopric of Segovia and the flourishing of the city of Toledo.

The general objective of this research is to determine what was the mode of operation of terrestrial vertebrates small and big , and the importance that they had in the survival of human populations that occupied the coastline during the late Holocene last years.
This book offers a valuable contribution to the development of a methodology to address the study of archaeological quartz artifacts, combining various analytical tools to study these objects so that we might better understand the technological strategies of hunting societies who made use of this raw material. Paperback; xmm; pages; illustrated throughout with 67 plates in colour. This book deals with the documentation and interpretation of the rock sites located in La Mancha center Spain , from the detailed study of the symbols that have been engraved in the rock.
These sites, from historical times, can provide valuable information for the study of the mentalities and beliefs of the popular classes during the Modern Age, strongly influenced by the atmosphere created after the Counter-Reformation. Crosses, calvaries, orbs, human and animal representations, letters, cup-marks and game boards make up an authentic symbolic universe, of clear Christian roots, whose understanding is possible to achieve even though it requires collaboration between multiple fields of knowledge such as archaeology, theology, numismatics, heraldry, architecture, sculpture, painting Unfortunately, researchers have paid scant attention to the issue at hand, assuming paradigms that from our point of view should be reviewed, such as the authorship of the petroglyphs or their chrono-cultural affiliation.
The study of the rock formations located in La Mancha center can shed light on these and other subjects, providing a good starting point in order to improve the documentation and interpretation of historical rock engravings in other parts of the world. This book presents, in sixteen papers, recent developments and some of the main topics seen in academic Medieval Archaeology studies in Spain.
The papers explore some of the emergent and consolidated topics of the discipline, such as landscapes, cities, rural spaces, bio-archaeological records, archaeology of architectures, agrarian archaeology, post-Roman archaeology, colonial archaeology in the Canary Islands and the archaeology of religious minorities, opening new lines of enquiries and providing new theoretical and methodological approaches.
An overview of Medieval Archaeology studies in Spain is offered, proposing a wide range of topics for discussion. Finally, the book explores the connections between Spanish Medieval Archaeology and other European traditions, specifically, English, Italian and Portuguese Medieval Archaeology. His principal interests lie in the study of the archaeology of landscapes, the archaeology of rural communities, Mediterranean Archaeology, Archaeology of Architectures, and the study of Social Complexity.
Besides, he is very interested in a multi-proxy and multidisciplinary approach to cultural resources. Currently, he is preparing a book about the Archaeology of Medieval Peasantry. This book presents the results obtained during geoarchaeological studies carried out in the locality of Touro Passo, municipality of Uruguaiana, Brazil.
The archaeological sites are located in the alluvial plains of the Uruguay River and the Touro Passo Stream and correspond to the late Pleistocene-early Holocene transition. The geoarchaeological approach allowed the understanding of the stratigraphic sequence and the processes of formation and post-depositional disturbance of the archaeological sites in a fluvial environment.
Archaeological excavations, soundings, stratigraphic profile surveys, sequence correlations and numerical dates were carried out. The dispersion of artifacts on the surface and cave erosion was recorded, and a lithic taphonomy study was carried out. The new chronologies obtained for the initial period of human occupation in the region represent a scientific advance for the study of hunter-gatherer occupations during the Late Pleistocene-Early Holocene in the triple border of Brazil, Argentina and Uruguay.
She acts as a consultant in archaeological and patrimonial research in environmental licensing, with experience in Precolonial research and Patrimonial Education. The site is a good example of past societies adaptation to hyper-arid environments, and provides new insights into the early human occupations of South America. The well-preserved stratigraphic record, together with 13 radiocarbon dates, show that the site was occupied around 11, cal BP.
One can highlight the presence of flakes of allochthonous raw-materials, imported from other areas, which have been flaked at Chipana-1 in order to produce bifacial tools. Chipana-1 was an important location for Late Pleistocene hunter-gatherer groups, poorly known until now, for the gathering of raw-materials and lithic production in the Atacama Desert. The site was integrated within a broader network of mobility that we are just starting to discover. Spanish text with English preface and abstracts. UK VAT This collective work, carried out by both senior and beginning researchers, is for those scholars who have their gaze fixed on the fascinating mosaic of cultures that was the North-African world from the moment Rome appeared in the region.
Even before this date, the arrival of Phoenicians on the continent and their subsequent spread throughout the north of it, initiated a rich process of contacts, interchanges and relations with the Libyan-Berber populations that inhabited the zone from time immemorial. All these subjects are treated in the present book through some specific scientific contributions whose geopolitical frame is the whole Proconsular Africa.
Most of the articles in this volume are dedicated to the world of images, but others also treat many other issues as Historiography, Archaeology of Architecture, Libyan-Berber ethnicities and even cultural parallels between North Africa and the Iberian Peninsula. The result of that research was the book Africa. In this case, she was specifically devoted to the study of the collection of sculptural materials belonging to the city and to the villas of the Tusculan surroundings.
Due to this research she published the volume Tusculana Marmora. She is specialist in the Libyan-Berber world, subject to which she dedicates her current doctoral thesis. His investigations are focused on Landscape Archaeology in the Baetica, Africa and Italy, besides his participation in research projects on domestic spaces in Pompeii and the Roman sculpture of Carthage.
Ya antes de esa fecha, la llegada de fenicios. The History of archaeological research has only recently become a research topic of interest within Spain. Eleven papers are presented in this proceedings volume. They address several aspects from different perspectives that collectively enrich the historiography of Spanish archaeological research.
