Soil Quality Assessment Using Geomatics Techniques For The Garraf River Basin

Overview of assessment in geographical areas (GIS) and model reviews, positioning (GNSS), positioning, this study was conducted for the purpose of estimating the soil quality of the Gharat River Basin in the north of Dhi Qar Governorate using geomatics techniques represented by geographic information systems (GIS), remote sensing (RS) and positioning systems (GNSS). Which is about (90 km) from the city center. In nature soils and the correlation (B / C) reached (R2 = 0.907) for sand, while the clay was correlation with the range (B / R) and it was (R2 = 0.763) in While the correlation between the silt and the band (B/R) was recorded (R2 = 0.730), the ph record (7.8-8.42) as it was classified as a neutral slant to the basal and it was clear from the statistical analysis that there is a relationship with the range (C / B) as it reached (R2 = 0.583). The results showed a decrease in the values of soil samples between (0.2 - 1.7%) and the results of the analysis. 0.114% -0.197%) and the results of the statistical analysis showed the correlation of the range (C/NIR) and gypsum with a correlation value of (R2 = 0.686) in the proportion of lime ranged between (64.5% -21.5%) and the statistical analysis showed a correlation between calcium carbonate and the relativity of the range (C / NIR) as recorded (R2 = 0.513), the results of the analysis of samples from the study samples ranged between (26.86-395.55), and through the statistical analysis it was found that there is a relationship between the rate of sodium adsorption and the ratio of the bandwidth of the satellite visual correlation amounted to (R2 = 0.736), and it ranged The electrical conductivity values for the soils of the study area (5.79 -44.2 dS.m¯1) and it was a correlation (G / R) and the correlation value was (R2 = 0.602), the calcium values in the area. The study ranged between (400-1944 ppm) and the correlation numbering (R2 = 0.640) and the rates of magnesium in the study table ranged, the correlation coefficient (R2 = 0.602), the sodium record between (50-1307 ppm) and the correlation range was (C / NIR) ) Correlation coefficient reached (R2 = 0.920), calcium carbonate ratios were found in the study stations (64.5% -21.5%) and its ratio reached with the range (C / NIR) as the proportion of gypsum in the region was calculated. The correlation coefficient of gypsum and range (C / NIR) was calculated) where it reached (R2 = 0.686), the sodium adsorption ratio (SAR) was calculated and meals were between (26.86-395.5) and there was an association with the range (B / R + NIR) as it was recorded (R2 = 0.737)

Volumetric threshold of pituitary macroadenoma as a predictor to visual impairment

Purpose: In this study, we aimed at correlating the curve of visual impairment against pituitary macroadenoma size. Method: In this study, we retrospectively analyzed the visual correlation between the volume and dimensions of pituitary adenoma and the degree of visual impairment on patients’ examination. 35 patients with no history of eye or refraction disorder were included in the study. Spearman correlation test was used to validate the correlation. Results: 57 % of pituitary macroadenoma patients suffer from visual impairment, even if not the primary presentation. Macroadenomas greater than 5 cm³ in volume and/or 2 cm height are more likely to cause various degrees of visual impairment, this correlation is not linear beyond these values. Conclusion: Visual impairment due to pituitary adenomas is more frequent than the presentation, the threshold volume is 5 cm³ and height is 2 cm, bigger adenomas behaviour is more multifactorial than the only size.

Personal Style in Portraiture Painting – ‘Visual Dialogues with Water’ Analysis of the Portraiture by Eddy Ochieng

Portraiture is arguably one of the most celebrated genres of art and artistic expression through the ages. Artists have always sought to create depictions of themselves in self-portraits as well as the depiction of sitters through in-person posed sessions, referencing, or imagination. They have also used portraiture for artistic expression particularly when aiming to depict human feelings and emotions for the practical reason that human expression itself is synonymous with facial expression. It is only through the study of physical facial expression that an artist is able to derive artistic expression in a continuum that ranges from extreme joy signified by laughter to extreme distress, signified by tears. In between the continuum is a whole retinue of feelings and emotions, such as amusement, happiness, irritation, anger, sorrow, despair, fear, anxiety, sadness, and many other human manifestations that emanate from life’s experiences. Apart from the obvious outer facial expressions, there are also the innate expressions that underscore personality and character that artists wish to unearth, study, and explore in their subjects. To execute and achieve these expressions in portraiture, the artist uses selected media, styles, and techniques that best suit the desired objective. This paper posits that there exists a correlation between individual style and the effectiveness of the intended purpose of portraiture where effectiveness applies to the communicative or expressive value of a portrait as well as its overall acclaim. It must be noted that there is no portraiture that lacks intent, be it portrayal of likeness from self-portraits or sitters or portraits derived from photographs, thematic referencing that leads to the depiction of certain facial expressions in subject matter or creating portraiture from imagination including surrealistic inspirations. When certain portraiture is at times perceived as not being effective in terms of its intent, it is fair to conclude that this may often be as a result of the personal style of the artist or its execution being incompatible with the intended purpose. Hence viewers fail to see or extract what was intended for them to decipher essentially because they are distracted by the personal style. In the same token, when portraiture is seen to be effective, it is often presupposed that this is a result of the personal style of the artist and its execution being deemed compatible with its intended purpose. Hence to a significant extent, the viewer is able to extract this purpose because they are aided by rather than distracted by the style and specifically, personal stylistic rendition. This paper examines the portraiture of Eddy Ochieng, an outstanding Kenyan hyperrealist in order to ascertain whether there exists this visual correlation between his personal style and the intent of his portraiture. He embraces the hyperrealism style featuring some self-portraits as well as of others derived from photographs. The inquiry is whether this style delves into any other meaning other than the quest for the photographic representation of likeness and whether the likeness itself is effectively extracted.

Exploring the visual correlation of choropleth maps using an evolutionary algorithm

Multivariate choropleth maps are often used to compare patterns of different spatial variables. This approach can be implemented by simultaneously drawing a series of choropleth maps, with each representing a particular variable. In this paper, we develop an evolutionary algorithm that can be used to generate a set of classifications that allow a user to explore the spatial patterns of multiple choropleth maps in terms of their visual correlation. Synthetic and census data are used to demonstrate the effectiveness of our approach. We also discuss the role of our approach in an interactive mapping environment and its implication for spatial data mining.

Spatial Distribution Of Atmospheric Pollutants Through Biomonitoring In Tree Bark Using X-Ray Fluorescence

Several studies have shown that tree barks can absorb air contaminants, therefore, trees can be used as biomonitors to identify the distribution of atmospheric pollutants. The city of Paranaguá, located at the coast of the Paraná State in Brazil, hosts the largest bulk cargo port in Latin America and an elevated number of fertilizer processing industries. In this study we used tree barks coupled to X-ray fluorescence spectrometer analysis to biomonitor the distribution of air pollutants in the city of Paranaguá. We identified a visual correlation between the level of the elements K and Cl, with high levels detected near fertilizer warehouses. A relation between Fe levels and position of railways and train stations were also clear. The low levels of the elements Zn, Al, Ba and Mg detected in a traffic restricted zone confirm the use of these elements as markers of vehicles traffic and validate the approach of using tree barks for air pollution biomonitoring.
