Proportional Variation of Potential Groundwater Recharge as a Result of Climate Change and Land-Use: A Study Case in Mexico

This work proposes a methodology whereby the selection of hydrologic and land-use cover change (LUCC) models allows an assessment of the proportional variation in potential groundwater recharge (PGR) due to both land-use cover change (LUCC) and some climate change scenarios for 2050. The simulation of PGR was made through a distributed model, based on empirical methods and the forecasting of LUCC stemming from a supervised classification with remote sensing techniques, both inside a Geographic Information System. Once the supervised classification was made, a Markov-based model was developed to predict LUCC to 2050. The method was applied in Acapulco, an important tourism center for Mexico. From 1986 to 2017, the urban area increased 5%, and by 2050 was predicted to cover 16%. In this period, a loss of 7 million m3 of PGR was assumed to be caused by the estimated LUCC. From 2017 to 2050, this loss is expected to increase between 73 and 273 million m3 depending on the considered climate change scenario, which is the equivalent amount necessary for satisfying the water needs of 6 million inhabitants. Therefore, modeling the variation in groundwater recharge can be an important tool for identifying water vulnerability, through both climate and land-use change.

SOMATOTYPOLOGICAL CHARACTERISTICS OF STUDENTS OF DIFFERENT HEALTH GROUPS BY R.N. DOROKHOV AND V.G. PETRUKHIN METHOD

A total of 381 girls aged 17–20 years of different health groups were evaluated. Dimensional and proportional variations of the physical parameters, body component composition were analyzed by R.N. Dorokhov and V.G. Petrukhin method. Was found that the overwhelming number of women belong to the microsomal (dimensional variation), to the microcorpulent (fat component composition), to the micro-bone (bone component composition), to the micro-muscle (muscle component composition) somatic types in all three groups. According to the proportional variation of the physical parameters, a heterogeneous distribution pattern was observed.

Study of Proportional Variation of Geopolymer Concrete which Self Compacting Concrete

Portland cement production process which is the conventional concrete constituent materials always has an impact on producing carbon dioxide (CO2) which will damage the environment. To maintain the continuity of development, while maintaining the environment, Portland cement substitution can be made with more environmentally friendly materials, namely fly ash. The substitution of fly ash material in concrete is known as geopolymer concrete. Fly ash is one of the industrial waste materials that can be used as geopolymer material. Fly ash is mineral residue in fine grains produced from coal combustion which is mashed at power plant power plant [15]. Many cement factories have used fly ash as mixture in cement, namely Portland Pozzolan Cement. Because fly ash contains SiO2, Al2O3, P2O3, and Fe2O3 which are quite high, so fly ash is considered capable of replacing cement completely.This study aims to obtain geopolymer concrete which has the best workability so that it is easy to work on (Workable Geopolymer Concrete / Self Compacting Geopolymer Concrete) and obtain the basic characteristics of geopolymer concrete material in the form of good workability and compressive strength. In this study, geopolymer concrete is composed of coarse aggregate, fine aggregate, fly ash type F, and activators in the form of NaOH and Na2SiO3 Be52. In making geopolymer concrete, additional ingredients such as superplastizer are added to increase the workability of geopolymer concrete. From this research, the results of concrete compressive strength above fc' 25 MPa and horizontal slump values reached 60 to 80 centimeters.

Longitudinal Changes in Body Composition Assessed Using DXA and Surface Anthropometry Show Good Agreement in Elite Rugby Union Athletes

Rugby union athletes have divergent body composition based on the demands of their on-field playing position and ethnicity. With an established association between physique traits and positional requirements, body composition assessment is routinely undertaken. Surface anthropometry and dual-energy X-ray absorptiometry (DXA) are the most common assessment techniques used, often undertaken synchronously. This study aims to investigate the association between DXA and surface anthropometry when assessing longitudinal changes in fat-free mass (FFM) and fat mass (FM) in rugby union athletes. Thirty-nine elite male rugby union athletes (age: 25.7 ± 3.1 years, stature: 187.6 ± 7.7 cm, and mass: 104.1 ± 12.2 kg) underwent assessment via DXA and surface anthropometry multiple times over three consecutive international seasons. Changes in the lean mass index, an empirical measure to assess proportional variation in FFM, showed large agreement with changes in DXA FFM (r = .54, standard error of the estimate = 1.5%, p < .001); the strength of association was stronger among forwards (r = .63) compared with backs (r = .38). Changes in the sum of seven skinfolds showed very large agreement with changes in DXA FM (r = .73, standard error of the estimate = 5.8%, p < .001), with meaningful differences observed regardless of ethnicity (Whites: r = .75 and Polynesians: r = .62). The lean mass index and sum of seven skinfolds were able to predict the direction of change in FFM and FM 86% and 91% of the time, respectively, when DXA change was >1 kg. Surface anthropometry measures provide a robust indication of the direction of change in FFM and FM, although caution may need to be applied when interpreting magnitude of change, particularly with FM.

PROPOSED INDEX CALCULATION FOR ECONOMICS RANKING

Index; is a display in which more than one variable is included and is used to measure the proportional variation of the movements of these variables. Indices are useful because they allow summarization and comparison by making the data simple. In this study; a new index calculation has been proposed with the help Fuzzy Clustering method. Calculation of Index prepared with 10 index values used in the literature. The indices are; Open Market, Budget Transparency, European 2020-Competitiveness, Economic Freedom (by Heritage Foundation), Economic Freedom (by Fraser Institute), Depth of credit information, Financial Stability, Trade Facilitation, Financial Inovation and Global competition. FCM Calculations are made with Matlab.2016 and other calculations are made with Microsoft Excel.2017 programmes. There are variables which have different numbers and structures used in each index calculation. These variables have different weights within themselves. In this study, weights were calculated for the new index value which will be created by using the sequences created because of these indices. The weights of each index value obtained by the Fuzzy Clustering Analysis are multiplied by the index values to create a new index order. European countries were re-ordered under the title “Economy”. It can interpret this new index order as a general summation of all other orders. Thus, the order of the countries under different subject headings will be calculated together with the orders in a specific area (economy, law etc.).

Serpentine Life: The Nature of Movement in Gothic, Mannerism and Baroque

In many ways, movement is a test case for visual art as much as for philosophy: for both, we have to answer the question of whether they create real movement or merely a representation of it. Does the event really take place or is it only an illusion? This is a problem that pertains especially to Mannerism and the baroque, which rely heavily on the vocabulary of force and movement that has invested the field of art since the Renaissance. Although these styles are still dominated by classical figuration, they also introduce all sorts of distortions, deformations, and exaggerations in it. Mannerism and the baroque are attempts, within representation, to present the unrepresentable and to render visible the invisible. As a consequence, stable form is no longer the foundation of the image, but rather the limit of visual evidency. Inseparable from its relation to the formless, extension itself becomes a delimitation of intensity, a participation in the infinite. Yet the question remains: Have these attempts merely produced sensational and metaphorical works of art that are meant to move us by generating an illusion of movement in what is undeniably a stable structure or a framed picture, or are they somehow literally moving in themselves? The second position is held by Gilles Deleuze. In Francis Bacon: The Logic of Sensation, he develops a deep connection between Bacon and Michelangelo, since Mannerist painting discovered the ‘figural’: the point at which abstract movements or forces are rendered visible within classical figuration such that the organic figurability of sensation is enriched with an inhuman becoming. In his The Fold: Leibniz and the Baroque, Deleuze then goes on to show how the baroque introduces movement in classical art by means of infinite folding, such that forms would emerge from and dissolve into folds: ‘[t]he object is manneristic, not essentializing: it becomes an event’. The first position, by contrast, is taken up by Lars Spuybroek in The Sympathy of Things: Ruskin and the Ecology of Design (2011), who contrasts Mannerism and the baroque with the Gothic, arguing that while the former work away from static form to deformation, only the latter directly imitates the vicissitude and variety of living nature and produces movement in its continuous working towards form. For no matter how much we deform the painted figure and render it dynamic, it remains imprisoned within a frame hanging motionless on a wall. And no matter how much we cover a classical structure with lifelike ornament, it remains a lifeless construction. Worse still, each time we produce an image or effect of movement in this way, our experience actually becomes more detached from real movement than attached to it. ‘The Baroque,’ Spuybroek therefore concludes, ‘is merely distorted classicism’. The proposition I put to the test is that, to a certain, to be determined extent, we should differentiate between Mannerism and the baroque in a way analogous to Spuybroek’s distinction between the Gothic and the baroque. For while the Mannerist fine arts certainly do not arrive at the free aggregation of lines of Gothic ornament, as they are based on the (dis)proportional variation of the single human body rather than on configural variation, they also lack, or do not yet succumb to, the continuity and smoothness of the baroque. Whereas the baroque brings all movement back to a spectacular sensuality and physicality, we still find a much more abstract, or inorganic, experience in Mannerism. It is that of the life of the serpentine line, or what William Hogarth would later call the ‘line of grace’.

Effect of Dispersion Medium and Dominated Evaporation on the Pattern Formation of Colloidal Suspension

We study the effect of dispersion medium and dominated evaporation on the drying process and pattern of thin liquid layer colloidal suspention. Panasonic camera is used to capture the drying process and macroscopic pattern. It is shown that drying patterns are sensitive to the dispersion medium. As the volume ratio of ethanol in aqueous ethanol colloidal suspension increases, the evaporation rate increases, and film in the center becomes smaller and thinner, obvious broad-ring pattern can be observed. We suggest that difference in dispersion medium changes the evaporation rate, which has a direct proportional variation with strength of Marangoni convection. Furthermore, convection strength has great influence on self-assembly of colloid particles and the pattern formation of colloidal suspension. We design two simple experiments to change the evaporation rate and convection strength in order to verify the conclusion above. Broad-ring patterns with spray-like round edge at higher evaporation rate are obtained. Uniform film forms at lower evaporation rate.

The clotting plot—an analysis of the kinetics of the blood clotting reactions

Despite the complexity of blood coagulation reactions there are two linear mathematical relations between clotting time and concentration of clotting factors. One of these relations connects clotting time and reciprocal of concentration, and holds only when several clotting factors are reduced simultaneously. Experiments were carried out to determine which combinations of reduced factors were associated with reciprocal linearity. The hypothesis is put forward that the chain reaction which results in clotting is viewed as a whole in the clotting time test and that linearity results when the whole reaction runs in a balanced and organized manner. Proportional variation of a single clotting factor will seldom have this effect.
