This research aims to assess the stability of the Bung Xang Lake embankment in the context of changing water levels due to change climate, specifically recent high tides. In this research, data from two cross-sections were collected and analyzed using Plaxis 2D V22 software. The simulation results indicate that the piles with a length of 11.30 meters, as per the design, still fall within the deformation range of the subsoil, especially at the surveyed location with weak and thick geological conditions (MC2-2), which limits the effectiveness of the piles.

In this paper, we design and build a model of a centralised storage system, using big data mining to provide business data analysis functions according to their business requirements. To test and evaluate the effectiveness of the proposed model, we use the input data which is the actual business data set of an accessory business.

The investigation of magnetic field strength variations over subterranean layers may reveal their locations on Earth’s surface and provide physical and geometrical characteristics. Magnetic studies were carried out around Gölcük caldera lake using proton magnetometers to identify subsurface volcanic structures. The acquired data were inverted using four different edge detection algorithms such as analytic signal, tilt angle, theta map, horizontal gradient. Afterwards, the results were used to determine the locations of the anomalous structures.

Gravity data inversion or interpretation requires the removal of the gravitational effects of the a priori known geologic and/or morphologic features within the Earth’s system to model and reveal the remaining signals of the unknown anomalous subsurface density distributions. The Bouguer gravity anomalies reduced by the normal gravitational field of the Earth and the gravitational attraction of the topographic masses above the sea level are frequently used in geophysics for this purpose.

In order to compare species compositions of ostracods, 25 streams and 15 lakes were sampled in the spring, summer, and autumn seasons of 2018. A total of 26 ostracod species were found in lakes (18 spp.) and streams (12 spp.). The Shannon index (H’) and evenness values of streams were higher than in lakes in all seasons. The highest H’ values for all combined (lakes + streams) and lake data were reported in the autumn season, and in spring the highest values were in streams.

Capoeta kosswigi was described from Lake Van basin, Turkey, being close to C. damascina and C. umbla. It is distinguished from them by a pointed snout and a small horseshoe-shaped mouth, and differing from C. damascina by having smaller scales, and from the C. umbla by processing larger scales. In this study, we tested the suggested synonymy hypothesis of C. kosswigi and C. damascina by comparing the morphometric and meristic data. The results revealed that all morphometric and meristic characters of C. kosswigi overlap with those of C. damascina.

The research was conducted in Kisumu County; based on 167 respondents (5 state departments for Trade Directorate heads, 8 beach managers and 154 fishers) in the selected beaches along Lake Victoria. The beaches and fishers were included in the sample using systematic random sampling technique and Nassiuma (2000) sampling formulae respectively.

Surajpur Lake is a prominent wetland site in National Capital Region, India, known for its rich avifaunal and aquatic biodiversity. The present study was carried out to analyse water quality and to check the relationship among various physicochemical parameters in both temporal and spatial scales from March 2012 to February 2013. The water samples were collected from five different locations on monthly basis. Standard methods were followed for the collection, sampling and analysis for 12 physicochemical parameters. The data were analyzed using PAST (version 2.15) software.

Biotic indices to monitor water quality are helpful tools for evaluating the health of rivers. Water quality analysis is mainly done using physical and chemical attributes in the DR Congo. The objectives of this study were to assess the biological water of Cirhanyobowa River using macroinvertebrate index and the relationship between physicochemical parameters and the ecological index from January to December, 2017. Eight physicochemical parameters and abundance of macroinvertebrates were obtained for 6 sites from upstream to downstream part, with different land uses.

This study aims to evaluate the reduction of evaporation of Lake Nasser’s water caused by disconnecting (fully or partially) some of its secondary channels (khors). This evaluation integrates remote sensing, Geographic Information System (GIS) techniques, aerodynamic principles, and Landsat7 ETM+ images.

Viral hemorrhagic septicemia virus (VHSV) is one of the most serious pathogens of finfish worldwide in terms of its wide host-range, pathogenicity, disease course, and mortality rates. The disease was first documented in the 1930s in Europe in association with heavy losses in rainbow. Data collected over 50 years show that VHSV is a virus of marine origin: its ability to alternate between marine and freshwater environments remains an enigma which requires further investigation. In 2003, VHSV invaded the Laurentian Great Lakes basin causing devastating losses.

Wadi El Raiyan is a great depression located southwest of Cairo in the Western Desert of Egypt. Lake Qarun, located north of the study area, is a closed basin with a high evaporation rate. The source of water in the lake is agricultural and municipal drainage from the El Faiyum province. In 1973, Wadi El Raiyan was connected with the agricultural wastewater drainage system of the Faiyum province and received water that exceeded the capacity of Lake Qarun. Two hydrogeological regimes have been established in the area: (i) higher cultivated land and (ii) lower Wadi El Raiyan depression lakes.

The activities of the Sasa mine have led to industrial discharge being released into Lake Kalimanci since the beginning of mining activity in 1954. For this reason, an ecological risk assessment is urgently required. In the present study, surficial lake sediments were analyzed using inductively coupled plasma mass spectrometry (ICP-MS), with all geochemistry data processed using Statistica 8.

The Storage Engine is a resource provider. When the relational engine attempts to execute a T-SQL statement that accesses an object for the first time, it calls upon the storage engine to retrieve the object, put it into memory and return a pointer to the execution engine. To perform these tasks, the storage engine manages the physical resources for the TOE by using the Windows OS. The SQL-OS is a resource provider for all situations where the TOE uses functionality of the operating system. SQL-OS provides an abstraction layer over common OS functions and...

On an annual basis, the Great Lakes Commission - the repository for the Great Lakes – St. Lawrence River Water Use Database - sends an e-mail request for the pervious year’s water use data in the fall to states and provinces. All data are submitted to the repository in a Microsoft Excel or Access format then compiled into a single Microsoft Access database. All data are in one of two unit measures—millions of U.S. gallons per day (mgd) or millions of liters per day (mld)—and values are initially set to zero. Numeric values are required for all...

A large amount of information has accumulated on humic acids and related substances, which warrants the creation of an independent science of humic compounds. Two different concepts have emerged from the maze of data, one claiming humic compounds to be operational or fake compounds, produced by the analytical extraction procedures, and the other considering them to be natural compounds occurring in soils, rivers, lakes, oceans and their sediments.
