Geographical distribution of American cutaneous leishmaniasis and its phlebotomine vectors (Diptera: Psychodidae) in the state of Sao Paulo, Brazil

Background: American cutaneous leishmaniasis (ACL) is a re-emerging disease in the state of Sao Paulo, Brazil. It is important to understand both the vector and disease distribution to help design control strategies. As an initial step in applying geographic information systems (GIS) and remote sensing (RS) tools to map disease-risk, the objectives of the present work were to: (i) produce a single database of species distributions of the sand fly vectors in the state of Sao Paulo, (ii) create combined distributional maps of both the incidence of ACL and its sand fly vectors, and (iii) thereby provide individual municipalities with a source of reference material for work carried out in their area. Results: A database containing 910 individual records of sand fly occurrence in the state of Sao Paulo, from 37 different sources, was compiled. These records date from between 1943 to 2009, and describe the presence of at least one of the six incriminated or suspected sand fly vector species in 183/645 (28.4%) municipalities. For the remaining 462 (71.6%) municipalities, we were unable to locate records of any of the six incriminated or suspected sand fly vector species (Nyssomyia intermedia, N. neivai, N. whitmani, Pintomyia fischeri, P. pessoai and Migonemyia migonei). The distribution of each of the six incriminated or suspected vector species of ACL in the state of Sao Paulo were individually mapped and overlaid on the incidence of ACL for the period 1993 to 1995 and 1998 to 2007. Overall, the maps reveal that the six sand fly vector species analyzed have unique and heterogeneous, although often overlapping, distributions. Several sand fly species - Nyssomyia intermedia and N. neivai - are highly localized, while the other sand fly species - N. whitmani, M. migonei, P. fischeri and P. pessoai - are much more broadly distributed. ACL has been reported in 160/183 (87.4%) of the municipalities with records for at least one of the six incriminated or suspected sand fly vector species, while there are no records of any of these sand fly species in 318/478 (66.5%) municipalities with ACL. Conclusions: The maps produced in this work provide basic data on the distribution of the six incriminated or suspected sand fly vectors of ACL in the state of Sao Paulo, and highlight the complex and geographically heterogeneous pattern of ACL transmission in the region. Further studies are required to clarify the role of each of the six suspected sand fly vector species in different regions of the state of Sao Paulo, especially in the majority of municipalities where ACL is present but sand fly vectors have not yet been identified.

Flood Risk Assessment in Coastal Drainage Basins through a Multivariate Analysis within a GIS-Based Model

This paper presents a GIS-based multicriteria flood risk assessment and mapping approach applied to coastal drainage basins where hydrological data are not available. It involves risk to different types of possible processes: coastal inundation (storm surge), river, estuarine and flash flood, either at urban or natural areas, and fords. Based on the causes of these processes, several environmental indicators were taken to build-up the risk assessment. Geoindicators include geological-geomorphologic proprieties of Quaternary sedimentary units, water table, drainage basin morphometry, coastal dynamics, beach morphodynamics and microclimatic characteristics. Bioindicators involve coastal plain and low slope native vegetation categories and two alteration states. Anthropogenic indicators encompass land use categories properties such as: type, occupation density, urban structure type and occupation consolidation degree. The selected indicators were stored within an expert Geoenvironmental Information System developed for the State of Sao Paulo Coastal Zone (SIIGAL), which attributes were mathematically classified through deterministic approaches, in order to estimate natural susceptibilities (Sn), human-induced susceptibilities (Sa), return period of rain events (Ri), potential damages (Dp) and the risk classification (R), according to the equation R=(Sn.Sa.Ri).Dp. Thematic maps were automatically processed within the SIIGAL, in which automata cells (""geoenvironmental management units"") aggregating geological-geomorphologic and land use/native vegetation categories were the units of classification. The method has been applied to the Northern Littoral of the State of Sao Paulo (Brazil) in 32 small drainage basins, demonstrating to be very useful for coastal zone public politics, civil defense programs and flood management.

PK/DB: database for pharmacokinetic properties and predictive in silico ADME models

The study of pharmacokinetic properties (PK) is of great importance in drug discovery and development. In the present work, PK/DB (a new freely available database for PK) was designed with the aim of creating robust databases for pharmacokinetic studies and in silico absorption, distribution, metabolism and excretion (ADME) prediction. Comprehensive, web-based and easy to access, PK/DB manages 1203 compounds which represent 2973 pharmacokinetic measurements, including five models for in silico ADME prediction (human intestinal absorption, human oral bioavailability, plasma protein binding, bloodbrain barrier and water solubility).

Groundwater favorability map using GIS multicriteria data analysis on crystalline terrain, Sao Paulo State, Brazil

This paper presents the groundwater favorability mapping on a fractured terrain in the eastern portion of Sao Paulo State, Brazil. Remote sensing, airborne geophysical data, photogeologic interpretation, geologic and geomorphologic maps and geographic information system (GIS) techniques have been used. The results of cross-tabulation between these maps and well yield data allowed groundwater prospective parameters in a fractured-bedrock aquifer. These prospective parameters are the base for the favorability analysis whose principle is based on the knowledge-driven method. The mutticriteria analysis (weighted linear combination) was carried out to give a groundwater favorabitity map, because the prospective parameters have different weights of importance and different classes of each parameter. The groundwater favorability map was tested by cross-tabulation with new well yield data and spring occurrence. The wells with the highest values of productivity, as well as all the springs occurrence are situated in the excellent and good favorabitity mapped areas. It shows good coherence between the prospective parameters and the well yield and the importance of GIS techniques for definition of target areas for detail study and wells location.

Elementary Petri net inside RFID distributed database (PNRD)

Usually, a Petri net is applied as an RFID model tool. This paper, otherwise, presents another approach to the Petri net concerning RFID systems. This approach, called elementary Petri net inside an RFID distributed database, or PNRD, is the first step to improve RFID and control systems integration, based on a formal data structure to identify and update the product state in real-time process execution, allowing automatic discovery of unexpected events during tag data capture. There are two main features in this approach: to use RFID tags as the object process expected database and last product state identification; and to apply Petri net analysis to automatically update the last product state registry during reader data capture. RFID reader data capture can be viewed, in Petri nets, as a direct analysis of locality for a specific transition that holds in a specific workflow. Following this direction, RFID readers storage Petri net control vector list related to each tag id is expected to be perceived. This paper presents PNRD cornerstones and a PNRD implementation example in software called DEMIS Distributed Environment in Manufacturing Information Systems.

GIS-portal - Utredning och design av GIS-portal ochingående tjänst åt Vägverket

Denna rapport presenterar ett examensarbete på D-nivå där uppdragsgivaren har varit WM-data Consulting och kunden Vägverket Produktion.Vägverket har ett antal olika applikationer för geografisk information som ligger utspridda på företagets hemsida . För att samla alla applikationer på ett och samma ställe fick vi i uppdrag att göra en grundläggande utredning av en GIS-portal. Denna portal ska fungera som en enhetlig ingång där kartdata samkörs och visualiseras. Ytterligare en del i uppdraget var att utreda vad som borde förändras och förbättras i den redan existerande tjänsten Beläggning på vägarna. Denna tjänst kommer att fungera som en testapplikation för GIS-portalen.Målen med examensarbetet var att utreda vilka krav som finns på en GIS-portal och applikationen Beläggning på vägarna samt att beskriva de önskemål som finns på dessa. Ett designförslag och en funktionsbeskrivning arbetades fram för både tjänsten Beläggning på vägarna och för GIS-portalen. Utredningen kommer att ligga till grund för utveckling av en GIS-portal samt fortsatt utveckling och förbättringar av tjänsten Beläggning på vägarna.För att komma fram till ett resultat har vi använt oss av ett antal teorier om IT-tjänster, systemarkitektur och användbarhet. Förutom dessa teorier har även de intervjuer som utförts spelat en stor roll för vårt arbete. Vi har lagt en bra grund för Vägverket att fortsätta arbetet med utveckling av en GIS-portal och tjänsten Beläggning på vägarna.

Geografiundervisning om eller med GIS : En intervjustudie om gymnasielärares didaktiska val för implementering av GIS i geografiundervisningen

I studien har gymnasielärares didaktiska val för implementering av geografiska informationssystem (GIS) i geografiundervisningen undersökts. Resultatet baseras på intervjuer med sex stycken respondenter, vilka har framhållit sina erfarenheter, tillämpnings- och förhållningssätt till GIS. De slutsatser som framkommer är att respondenterna enbart använder webbaserade och kostnadsfria GIS-program i undervisningen. I dessa tillämpas GIS som ett verktyg för att behandla olika frågor i undervisningen, och därmed är det undervisning, med hjälp av GIS, som karakteriserar respondenternas användning. De didaktiska valen behandlar naturgeografiska förhållanden, såsom landformer. Vissa respondenter använder också GIS till att behandla frågor med utgångspunkt i kulturgeografiska förhållanden, till exempel olika typer av befolkningsfrågor. Att arbeta tvärvetenskapligt i GIS, således mot ämnets två vetenskapliga discipliner, är inte karakteristiskt för alla respondenter. Dessutom använder ett fåtal respondenter fortfarande kartboken, eller låter eleverna rita kartor för hand.   Nästan alla respondenter anser att de vill, och behöver, öka användningen av GIS i och med utformningen av de nya kursplanerna för geografiämnet i Gy11. Emellertid hämmas respondenternas möjligheter att undervisa i geografiska informationssystem av en kombination av brist på tid, resurser och kunskap. 

Conceptualizing Wilderness Through GIS

The word “wilderness” in America is generally identified with pristine places where humans are not among the primary influences on the land and its ecology. The American wilderness ethic creates a strict dichotomy between humans and nature. The Wilderness Preservation Act of 1964 defines wilderness as “an area where the earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain” (wilderness.net). This statutory definition of wilderness is essentially the functional embodiment of the American wilderness ethic. Wilderness can also be interpreted in ways that incorporate humans as active players in the natural world. Land which is managed for human use but is uninhabited can be considered wilderness to some degree because “man himself is a visitor who does not remain.” Wilderness, especially in the Northeast, can be visualized based on different land use characteristics. Conservation in the Northeast requires a redefinition of wilderness in order to incorporate land that has been utilized by humans.
