SIE-SECURITY

The purpose of this paper is to present the application named SIE-Security providing web programmers with a tool that searches vulnerable links within their web site (i.e. a product page), attempting to perform an SQL Injection and finally, trying to find the admin login page and crack the MD5 hashed password (inappropriately called “crack” because we are actually using Rainbow tables). The application is structured on three tabs, each corresponding to the actions performed by the application and, if you take into consideration that this is a project in development, it could be considered an All-In-One database security testing utility.commerce, application, vulnerable, attack, decryption, security, testing

Spatio-temporal insights into microbiology of the freshwater-to-hypersaline, oxic-hypoxic-euxinic waters of Ursu Lake

Ursu Lake is located in the Middle Miocene salt deposit of Central Romania. It is stratified, and the water column has three distinct water masses: an upper freshwater-to-moderately saline stratum (0–3 m), an intermediate stratum exhibiting a steep halocline (3–3.5 m), and a lower hypersaline stratum (4 m and below) that is euxinic (i.e. anoxic and sulphidic). Recent studies have characterized the lake's microbial taxonomy and given rise to intriguing ecological questions. Here, we explore whether the communities are dynamic or stable in relation to taxonomic composition, geochemistry, biophysics, and ecophysiological functions during the annual cycle. We found: (i) seasonally fluctuating, light-dependent communities in the upper layer (≥0.987–0.990 water-activity), a stable but phylogenetically diverse population of heterotrophs in the hypersaline stratum (water activities down to 0.762) and a persistent plate of green sulphur bacteria that connects these two (0.958–0.956 water activity) at 3–3.5 to 4 m; (ii) communities that might be involved in carbon- and sulphur-cycling between and within the lake's three main water masses; (iii) uncultured lineages including Acetothermia (OP1), Cloacimonetes (WWE1), Marinimicrobia (SAR406), Omnitrophicaeota (OP3), Parcubacteria (OD1) and other Candidate Phyla Radiation bacteria, and SR1 in the hypersaline stratum (likely involved in the anaerobic steps of carbon- and sulphur-cycling); and (iv) that species richness and habitat stability are associated with high redox-potentials. Ursu Lake has a unique and complex ecology, at the same time exhibiting dynamic fluctuations and stability, and can be used as a modern analogue for ancient euxinic water bodies and comparator system for other stratified hypersaline systems

THE FREQUENCY OF OCCURRENCE OF FLASH FLOODS ON THE RIVERS IN THE LAND OF DORNA

Flash floods are extreme natural phenomena that determine numerous property damage and loss of human life on both global and local level. In order to highlight not only the frequency of occurrence of floods on the rivers in the Land of Dorna but also their effects on the community, we set ourselves to perform a secondary analysis of data provided by Siret River Basin Administration. As a result, one can observe that the highest frequency of occurrence of flash floods in the region of Dorna is in the spring. During the same period of time (from 1993 to 2003) there were recorded only significant property damages after the flash floods. At the end of this paper we suggested a series of coherent measures in order to combat the negative effects of flash floods

L'évolution du modelé lacustre et la salinité des lacs de Cojocna (plaine de Transylvanie, Roumanie) (Morphological evolution and salinity of Cojocna lakes (Transylvanian plain, Romania))

Salt lakes of Cojocna are located on a salt diapir in the Western part of the Transylvanian Basin. Their origin is anthropic (collapse of sedimentary materials which were covering the salty mines) and natural (salt dissolution). The basins are characterized by a very active dynamics : the increased filling, the mobility thresholds between the old mines, the general reduction of the slope, the mergering of many pits, the rapidity of the dissolution process at the contact between water and salt. Salinity differs from one lake to another. Lakes where the sedimentary material have not isolated salt from water show an important growth of salinity from surface to bottom (Durgǎu lake — 42 g/l at 0,5 m and 249 g/l at 43,8 m). When salt was separated from water through sedimentary materials, salinity has decreased to minimal values ; can appear inversions of the values, in the case of pumping out water from one lake to another to maintain the constant level. Due to the very great tourist flux, theses lakes must be preserved and the authors suggest a new town planning.Les lacs salés de Cojocna sont situés sur un diapir à l'ouest du bassin transylvain. Ils sont nés de l'effondrement de toits de mines de sel abandonnées, puis de leur inondation. Leur évolution est extrêmement rapide du fait de la dissolution des évaporites, qui réduit les seuils, fait entrer en coalescence les anciens puits et amoindrit les pentes. Deux types de lacs ont une évolution divergente. Les premiers, comme le lac Durgǎu, conservent une dissolution active, que confirment leur hypersalinité et la croissance des concentrations de la surface vers le fond. Les seconds, comme le lac des Bains, ont subi un colmatage tel que la dissolution est gênée par une barrière sédimentaire. Ils sont en cours de comblement et leur salinité décroît, perdant alors leur attractivité touristique et curative. Les auteurs font des propositions d'aménagement pour préserver ces plans d'eau.Serban Gheorghe, Alexe Mircea, Touchart Laurent.

THE USAGE OF TECHNOLOGIES IN TERRESTRIAL MEASUREMENTS FOR HAZARD MAPS

In the context of natural phenomena (earthquakes, floods, landslides etc.) bring economical and social prejudices year by year, watching on them and taking decisions becomes mandatory for reducing the material and human lives loss. Making hazard maps represents a tool used on wide global scale but also particularly in our country. This paper work has the purpose to reveal the interests of certain authors related to the usage of the new technologies of terrestrial measurements (GPS technologies, photogrammetry, cartography and of remote sensing) in order to make these hazard maps

Change detection in the cluj forest district using remote sensing and gis application

International audienceThis paper focuses on the testing and comparison of the sensitivity of vegetation indices to determine the changes occurred in forest areas of the Cluj Forest District during the post-socialist period, between 1986 and 2009. Concurrently, the paper pursues to assess the way in which the socioeconomic and social changes have caused alterations of the forest areas. These have been significantly affected by the changes occurred over the past decades, as well as by the increase of the anthropization degree of the natural areas. Remote sensing applications are very efficient tools in detecting and assessing the changes both in space and over time. Two vegetation indices were used-NDVI and SAVI. The results show the spatio-temporal dynamics of the vegetation cover for approximately one third of the area, as the used indices presented decreasing values of up to 35% (NDVI 27%, SAVI 32%). The accuracy of classifying indices in decreasing, increasing and no-change areas is 88.20%, while the Kappa coefficient is 0.82. In addition, user's and producer's accuracy was calculated for each class
