Core Ideas

PTFs for water contents at specific pressure heads were developed.

Covariate shift increased uncertainty in PTF predictions.

Relative importance of predictors in machine learning PTFs was determined.

There has been much effort to improve the performance of pedotransfer functions (PTFs) using intelligent algorithms, but the issue of covariate shift, i.e., different probability distributions in training and testing datasets, and its impact on prediction uncertainty of PTFs has been rarely addressed. The common practice in PTF generation is to randomly separate the dataset into training and testing subsets, and the outcomes of this random selection may be different if the process is subject to covariate shift. We evaluated the impact of covariate shift generated by data shuffling and detected by Kolmogorov–Smirnov test for the prediction of water contents using soil databases from Denmark and Brazil. The soil water contents at different pressure heads were predicted by developing linear and stepwise regression besides machine learning based PTFs including Gaussian process regression and ensemble method. Regression based PTFs for the Brazilian dataset resulted in better predictions compared with machine learning methods, which in their turn estimated high water contents in Danish soils more accurately. One hundred PTFs were developed for water content at specific pressure heads by data shuffling. From these, 100 sets of fitted van Genuchten parameters were obtained representing the generated uncertainty. Data shuffling led to covariate shift, resulting in uncertainty in water content prediction by the PTFs. Inherent variability of data may lead to increased prediction uncertainty. For correlated data, simple regression models performed as good as sophisticated machine learning methods. Using PTF‐predicted water contents for van Genuchten retention parameter fitting may lead to a high uncertainty.

A new mineral, siwaqaite, ideally Ca6Al2(CrO4)3(OH)12·26H2O [P31c, Z = 2, a = 11.3640(2) Å, c = 21.4485(2) Å, V = 2398.78(9) Å3], a member of the ettringite group, was discovered in thin veins and small cavities within the spurrite marble at the North Siwaqa complex, Lisdan-Siwaqa Fault, Hashem region, Jordan. This complex belongs to the widespread pyrometamorphic rock of the Hatrurim Complex. The spurrite marble is mainly composed of calcite, fluorapatite, and brownmillerite. Siwaqaite occurs with calcite and minerals of the baryte-hashemite series. It forms hexagonal prismatic crystals up to 250 μm in size, but most common are grain aggregates. Siwaqaite exhibits a canary yellow color and a yellowish-gray streak. The mineral is transparent and has a vitreous luster. It shows perfect cleavage on (1010). Parting or twinning is not observed. The calculated density of siwaqaite is 1.819 g/cm3. Siwaqaite is optically uniaxial (–) with ω = 1.512(2), ε = 1.502(2) (589 nm), and non-pleochroic. The empirical formula of the holotype siwaqaite calculated on the basis of 8 framework cations and 26 water molecules is Ca6.01(Al1.87Si0.12)Σ1.99[(CrO4)1.71(SO4)1.13(SeO4)0.40]Σ3.24(OH)11.63·26H2O. X-ray diffraction (XRD), Raman, and infrared spectroscopy confirm the presence of OH- groups and H2O molecules and absence of (CO3)2– groups. The crystal structure of this Cr6+-analog of ettringite was solved by direct methods using single-crystal synchrotron XRD data. The structure was refined to an agreement index R1 = 4.54%. The crystal structure of siwaqaite consists of {Ca6[Al(OH)6]2·24H2O}6+ columns with the inter-column space (channels) occupied by (CrO4)2–, (SO4)2–, (SeO4)2–, and (SO3)2– groups and H2O molecules. The tetrahedrally coordinated site occupied by different anion groups is subjected to disordering and rotation of these tetrahedra within the structure. The temperature of siwaqaite formation is not higher than~70–80 °C, as is evident from the mineral association and as inferred from the formation conditions of the natural and synthetic members of the ettringite group minerals, which are stable at conditions of T < 120 °C and pH = 9.5–13. The name siwaqaite is derived from the name of the holotype locality—Siwaqa area, where the mineral was found.

Authors: Shkolnyk Inna , Bondarenko Eugenia , Balatskyi Ievgen
Published: November 2019

The Ukrainian stock market is rated as an emerging market, which is characterized by high profitability and higher risk level as compared to developed economies. Securities transactions on the Ukrainian stock market are accompanied by stable uncertainties. Moreover, insurance is the most effective way to reduce financial risks and their negative effects. Given the current economic and political instability, financial risk insurance can ensure the economic performance of business entities and stimulate their further economic development. Financial risk insurance is the liability insurance in its nature, but its terms are often included in property insurance. This insurance sector has considerable facilities, which require activation of new insurance products that will be able to protect individual and institutional investors. Insurance and stock markets are direct competitors for limited investor resources, including strategic sources such as temporarily free institutional investor funds and household savings. In general, although there is a significant interaction between the insurance and other financial markets in Ukraine, it is hardly realized at all, unlike foreign economies, where it is used to its maximum. With the development of the insurance culture of the population and insurance in general, the relevance of insurance services in a high-risk segment like the stock market increases. The article harmonizes types of financial risks arising on the stock market with the methods of their leveling (insurance, hedging, diversification, etc.), determines the risk factors of the investor in the stock market, and specifies the professional risks of financial institutions. For the Ukrainian stock market participants, the use of two types of insurance coverage, namely, Bankers Blanket Bond and Financial Institution Professional Indemnity, is proposed.

Authors: Wibowo Nurhida Rahmalia , Wimbarti Supra
Published: November 2019

Interaction among children with their parents and peers has an important role in developing aggression in adolescents. Negative interaction can form children’s negative perception of attachment to their parents and peers. In turn, it facilitates adolescent’s negative schemes from childhood to adolescence. Negative scheme children are generally easy to get anxious, difficult to trust another person in interaction, and aggressive. This study aimed to examine the perceptions of attachment effect to their father, mother, and peer on male adolescents' aggressive behaviors. The subjects of this study were 31 adolescents aged 12-15 years old, who lived in PSMP Antasena in Magelang. They were selected through purposive sampling technique. The data were collected using aggressive behavior scale and modification of parents and peer attachment inventory. The method used for analyzing data was multiple regression. The results of the analysis showed that R=0.688, p<0.01, indicating that the perceptions of father, mother and peer attachment significantly can predict aggression in male adolescents.

Published: November 2019

The intention of employees to leave the organization, or known as turnover intention, is something that must be taken seriously by an organization as it may affect the sustainability of the organization. This study aimed to determine the effect of resilience as a mediator in the relationship between future time perspective (FTP) and turnover intention. Data were taken using convenience sampling from various state-owned enterprises (Badan Usaha Milik Negara, BUMN) in Depok and Jakarta area (N = 310). The study used a self-rating method using 3 measurements, namely Zimbardo Time Perspective Inventory, Brief Resilience Scale, and Turnover Intention. Data were analyzed using mediation technique by Hayes’ PROCESS macro on SPSS program. The results showed that FTP negatively and significantly affected turnover intention and that resilience fully mediated the relationship. As a practical implication, this study provides information for organizations to employ programs to increase employees’ future time perspective and resilience.

Authors: Pan Fanghui , Wang Youbao , Zhang Xinxi
Published: November 2019

The frequent occurrence of sudden water pollution accidents has become a major threat to water environment safety. Although most researches have focused on constructing a pollutant source identification model and risk assessment methods for dealing with sudden water pollution accidents, a real-time, effective emergency measure for controlling pollutant diffusion, isolating and removing the pollutant, aiming at sudden water pollution accidents, has not been emphasized. Therefore, in this paper, a novel emergency approach of soft isolation was investigated to control pollution diffusion and decrease damage as soon as the accident occurred. In stage 1, the feature of pollution diffusion regarding a sudden water accident was predicted through a water quality model using computational fluid dynamics (CFD). Then, a design scheme of soft isolation was constructed in stage 2 to isolate the polluted zone and attention was paid to optimizing the parameters of soft isolation. Ultimately, the mathematical model of complete purification was formulated in stage 3 to remove the pollution from the impacted zone. The results indicated that the emergency measure of soft isolation could have significant potential to control and isolate pollution occurring in a sudden water pollution accident in the future.

Published: November 2019

Bioluminescent Proteins (BLPs) are widely distributed in many living organisms that act as a key role
of light emission in bioluminescence. Bioluminescence serves various functions in finding food and protecting
the organisms from predators. With the routine biotechnological application of bioluminescence, it is recognized
to be essential for many medical, commercial and other general technological advances. Therefore, the
prediction and characterization of BLPs are significant and can help to explore more secrets about bioluminescence
and promote the development of application of bioluminescence. Since the experimental methods are money
and time-consuming for BLPs identification, bioinformatics tools have played important role in fast and
accurate prediction of BLPs by combining their sequences information with machine learning methods. In this
review, we summarized and compared the application of machine learning methods in the prediction of BLPs
from different aspects. We wish that this review will provide insights and inspirations for researches on BLPs.

Published: November 2019

Background:

Nilatinib is an irreversible tyrosine kinase inhibitor, which is used in the
treatment of some kinds of cancer. To study the interaction between Neratinib and MAD2L1, a potential
tumor target, is of guiding significance for enriching the medicinal value of Neratinib.

Method:

The binding mechanism between Mitotic arrest deficient 2-like protein 1 (MAD2L1) and
Neratinib under simulative physiological conditions was investigated by molecule simulation and
multi-spectroscopy approaches.

Results:

Molecular docking showed the most possible binding mode of Neratinib-MAD2L1 and the
potential binding sites and interaction forces of the interaction between MAD2L1 and Neratinib.
Fluorescence spectroscopy experiments manifested that Neratinib could interact with MAD2L1 and
form a complex by hydrogen bond and van der Waals interaction. These results were consistent with
the conclusions obtained from molecular docking. In addition, according to Synchronous fluorescence
and three-dimensional fluorescence results, Neratinib might lead to the conformational change
of MAD2L1, which may affect the biological functions of MAD2L1.

Conclusion:

This study indicated that Neratinib could interact with MAD2L1 and lead to the conformational
change of MAD2L1. These works provide helpful insights for the further study of biological

Authors: Guvenir Hakan , Arikoglu Tugba , Vezir Emine , Misirlioglu Emine Dibek
Published: November 2019

Drug hypersensitivity reactions are clinically heterogenous ranging from mild to severe. Most drug hypersensitivity reactions are accompanied by cutaneous manifestations. Fever, mucous membrane involvement, large blisters, facial oedema, pustulosis and visceral involvement are clinical features that lead to suspicion of severe adverse drug reactions. Severe cutaneous adverse drug reactions (SCARs) include Stevens-Johnson syndrome, toxic epidermal necrolysis, drug rash eosinophilia and systemic symptoms, acute generalized exanthematous pustulosis. Serum sickness like reactions, drug induced vasculitis and generalized bullous fixed drug eruptions are less severe clinical entities. SCARs are uncommon but associated with significant morbidity and mortality. Physician should be aware of specific red flags and danger signs to immediately identify these reactions. Immediate drug withdrawal is mandatory. Early diagnosis and appropriate treatment significantly affect the prognosis of the disease. The purpose of our review is to discuss clinical phenotypes of severe cutaneous drug hypersensitivity reactions.

Authors: Prasad Malavattu G. , Lakshmi Chapala V. , Katari Naresh K. , Anand Krishnan , Pal Manojit , Jonnalagadda Sreekantha B.
Published: November 2019

Background:

The oxazolone class of compounds is known to exert a profound effect on
malignant cell proliferation, tumor angiogenesis and /or on the established neoplastic vasculature.
Additionally, these compounds are generally known to have a low tendency to interact with DNA
which is not common with most of the conventional cytotoxic agents. Thus, this class of compounds is
of particular interest for the discovery and development of patient-friendly anticancer agents.

Objective:

The initial objective of this study was to synthesize and evaluate 2-substituted 4-arylidene-
5(4H)-oxazolones for their potential anticancer properties.

Methods:

A simple, mild and non-hazardous synthetic methodology has been developed for the
preparation of 2-substituted 4-arylidene-5(4H)-oxazolones. The methodology involved lemon juice
mediated condensation of N-acyl glycine derivatives including hippuric acid with arylaldehydes in
PEG-400 under ultrasound irradiation. All the synthesized compounds were screened via an MTT
assay for their potential cytotoxic properties in vitro using the cancerous cell lines e.g. K562 (human
chronic myeloid leukemia), Colo-205 (human colon carcinoma), and A549 (human lung carcinoma)
and a non-cancerous HEK293 (human embryonic kidney) cell line.

Results:

Compounds 3a, 3c and 3i showed promising growth inhibition against A549 cell line but no
significant effects on HEK293 cell line, indicating their selectivity towards cancer cells. Moreover,
their IC50 values suggested that all these compounds were comparable to the reference drug
doxorubicin indicating their potential against lung cancer.

Conclusion:

he 4-arylidene-5(4H)-oxazolone framework presented here could be a new template for
the design and discovery of potential anticancer agents especially for lung cancer.
Non-coding RNA Associated Competitive Endogenous RNA Regulatory Network: Novel Therapeutic Approach in Liver Fibrosis
Authors: Riaz Farooq , Li Dongmin
Published: November 2019

Liver fibrosis or scarring is the most common pathological feature caused by chronic liver injury, and is widely considered one of the primary causes of morbidity and mortality. It is primarily characterised by hepatic stellate cells (HSC) activation and excessive extracellular matrix (ECM) protein deposition. Overwhelming evidence suggests that the dysregulation of several noncoding RNAs (ncRNAs), mainly long non-coding RNAs (lncRNAs), microRNAs (miRNAs) and circular RNAs (circRNAs) contributes to the activation of HSC and progression of liver fibrosis. These ncRNAs not only bind to their target genes for the development and regression of liver fibrosis but also act as competing endogenous RNAs (ceRNAs) by sponging with miRNAs to form signaling cascades. Among these signaling cascades, lncRNA-miRNA-mRNA and circRNA-miRNA-mRNA are critical modulators for the initiation, progression, and regression of liver fibrosis. Thus, targeting these interacting ncRNA cascades can serve as a novel and potential therapeutic target for inhibition of HSC activation and prevention and regression of liver fibrosis.

Authors: Joksimović Nenad , Petronijević Jelena , Janković Nenad , Kosanić Marijana , Milivojević Dušan , Vraneš Milan , Tot Aleksandar , Bugarčić Zorica
Published: November 2019

Background:

In order to make some progress in discovering the more effective way to
eliminate ROS which cause the oxidative stress in organism in humans and bearing in mind the
fact that ethyl-2-hydroxy-4-aryl(alkyl)-4-oxo-2-butenoates (β-diketonates) belong to a class of biologically
active compounds, series of β-diketonates were synthesized, characterized, and tested to
evaluate there antioxidant activity. Further, to investigate how coordination to copper(II) ion affects
the activity of β-diketonates, appropriate complexes were synthesized and characterized.

Methods:

All complexes were characterized by UV-Vis, IR, and EPR spectroscopy, MS spectrometry,
and elemental analysis. Fluorescence spectroscopic method was used for investigations of the
interactions between biomacromolecules (DNA or BSA) and compound 2E. Viscosity measurements
and molecular docking study were performed to confirm the mode of interactions between
DNA and BSA and compound 2E.

Results:

Scavenging activity on DPPH radical revealed that compounds 2A, 2B, and 2E possess
largest free radical scavenging, comparable to standard while results of superoxide anion scavenging
activities of tested samples showed that maximum scavenging activity (IC50=168.92 μg/mL)
was found for 2E, very similar to standard ascorbic acid, followed by 2B and 2G. Results of the
interactions between biomacromolecules and 2E indicated that 2E has the affinity to displace EB
from the EB-DNA complex through intercalation [Ksv = (3.7 ± 0.1) × 103 M-1], while Ka value obtained
via titration of BSA with 2E [Ka = (4.2 ± 0.2) × 105 M-1], support the fact that the significant
amount of the drug could be transported and distributed through the cells.

Conclusions:

All β-diketonates exhibited better scavenging activities than their corresponding copper
complexes. Among all the tested compounds, 2E gave the highest reducing power, even higher
than standard ascorbic acid, while reducing power for compounds 2A and 2B was also good but
lower than standard. DNA and BSA binding study for 2E showed that this compound has the potential
to be used as medicament.

Published: November 2019

Background:

Chalcones are naturally occurring compounds found in various plant species which are
widely used for the traditional popular treatments. Chalcones are distinguished secondary metabolites that are
reported to display diverse biological activities such as antiviral, antiplatelet, anti-inflammatory, anticancer,
antibacterial and antioxidant agents. The presence of a,ß-unsaturated carbonyl group in chalcones is assumed to
be responsible for their bioactivity. In addition, heterocyclic compounds having nitrogen such as isoquinolines
are of considerable interest as they constitute the core structural element of many alkaloids that have enormous
pharmacological activities.

Objective:

The objective of this study is the synthesis and biological activity of novel chalcones incorporating
thiadiazolyl isoquinoline as potential anticancer candidates. Different genetic tools were used in an attempt to
know the mechanism of action of this compound against breast cancer.

Methods:

An efficient one pot synthesis of novel chalcones incorporating thiadiazolyl isoquinoline has been
developed. The cytotoxic activity of the novel synthesized compounds was performed against four different
kinds of cancer cell lines.

Results:

Among all the tested derivatives, chalcone 3 has the best cytotoxic profile against A549, MCF7, and
HeLa cell lines, with IC50s (66.1, 51.3, and 85.1μM, respectively). Molecular docking studies for chalcone 3
revealed that CDK2, and EGFRTK domains have strong binding affinities toward the novel chalcone 3, while
tubulin-colchicine-ustiloxin, and VEGFRTK domains illustrated moderate mode of binding.

Conclusion:

We have developed an efficient method for the synthesis of novel chalcones incorporating thiadiazolyl
isoquinoline. All compounds showed better cytotoxicity results against four kinds of cancer cell lines
(A549, MCF7, HCT116, and HELA cells). The results depicted that chalcone 3 has a high and promising cytotoxic
effect against HELA cell line and the mechanism of cytotoxicity was widely studied through different
theoretical and experimental tools. Thus, the newly synthesized derivative 3 can be utilized as a novel chemotherapeutic
compound for cervical carcinoma.

The aims of this study were to describe patient utilization of an urgent care clinic (UCC) in a dental school for one year and to assess dental students’ perceptions of the benefits of training in this clinic. Aggregate clinic data from July 3, 2017, through July 6, 2018, were used to determine number of patients, number of new patients, number of new patients who elected to transfer their primary dental care to the university, number who were seen for a follow‐up, and service/clinic to which each patient was referred. Student evaluations were used to determine the benefits students perceived in their training in the UCC. Results showed that 1,674 patients were seen in the UCC during the study period. Of these, 67% were new patients, and 53% of these new patients opted to transfer their primary dental care to the university. An average of 7.03 patients were treated per day, and 2.48 new patients per day were generated for the predoctoral student clinic. The most common referrals were to oral surgery (37%), endodontics (30%), and the predoctoral dental clinic (28%). Among these patients, 39% scheduled follow‐up appointments, and the attendance rate was 69%. About 80% of eligible students (40/50) completed the questionnaire, and many provided optional comments. Over 80% of the responding students responded favorably regarding the learning experiences and assessments during the UCC rotation. This study found that establishment of the UCC increased the pool of patients and provided students the necessary experiences in triaging and treating dental emergencies.

Methods

Female employees at a private hospital were invited to participate in the study via mailing lists and intranet ads. A total of 653 individuals self-enrolled through the website. Eligible participants were randomized between control (n=240) and intervention (n=250) groups. The well-being mobile app provides an 8-week program with 4 classes per week (including a brief theoretical portion and a 15-min guided practice). The active control app also provided 4 assessments per week that encouraged participants to self-observe how they were feeling for 20 min. We also used the app to conduct Web-based questionnaires (10-item Perceived Stress Scale and 5-item World Health Organization Well-Being Index) and ask specific questions to assess subjective levels of stress and well-being at baseline (t1), midintervention (t4=4 weeks after t1) and postintervention (t8=8 weeks after t1). Both apps were fully automated without any human involvement. Outcomes from the control and intervention conditions at the 3 time points were analyzed using a repeated measures analysis of variance.

Results

Among the randomized participants (n=490), 185 participants were excluded at the 4-week follow-up and another 79 at the 8-week follow-up because of noncompliance with the experimental protocol. Participants who did not complete t4 and t8 assessments were equally distributed between groups (t4: control group=34.6% [83/240] and intervention group=40.8% [102/250]; P=.16; t8: control group=29.9% [47/157] and intervention group=21.6% [32/148]; P=.10). Both groups showed a significant increase in general well-being as a function of time (F2,426=5.27; P=.006), but only the intervention group presented a significant increase in work-related well-being (F2,426=8.92; P<.001), as well as a significant reduction in work-related and overall stress (F2,426=5.50; P=.004 and F2,426=8.59; P<.001, respectively).

Conclusions

The well-being mobile app was effective in reducing employee stress and improving well-being.

Published: November 2019

The Borneo Orangutan Survival Foundation (BOS) Foundation is an Indonesian non-profit organization dedicated to the conservation of the Bornean Orangutan and its habitat. The BOS Foundation is the largest reintroduction program in the world. This study aims firstly to describe the process of community-based social movements conducted by the Borneo Orangutan Survival Foundation (BOS) Foundation and secondly to describe the type and motive of social movement actors that give awareness of the importance of orangutan conservation. This research type is descriptive research. This study aims to describe the phenomenon in addressing Central Kalimantan Orangutan. The approach used is case study. The results of this study indicate that the emergence of BOS movement is caused by an endangered orangutan population. The destruction of forests has resulted in this endangered orangutan population, the loss of biodiversity, as well as rising greenhouse gas emissions that could trigger global warming. In addition to the impact of forest fires in 1997, the ex-PLG Million Ha area also caused a decrease in the Orangutan population. Therefore, BOS is present to make efforts to save the Orangutan
Evaluación de los parámetros del proceso de congelación para la pulpa de Açaí

La refrigeración y la congelación son procesos tradicionalmente utilizados en la conservación de alimentos. En el caso del açaí, una fruta brasilera, estas tecnologías corresponden a los métodos más empleados por la industria. La aplicación de modelos teóricos para la predicción de tiempos y temperaturas de congelación permite mantener un control eficaz de dicha operación. El objetivo de este trabajo fue estimar y evaluar el tiempo, temperatura y velocidad de dos procesos de congelación para pulpa de açaí, tanto convencional como criogénico. El tiempo de congelación convencional para el producto fue 153,68 ± 6,42 min, con mínimo error respecto a las ecuaciones de Pham (0,54 %) y Nagaoka (1,71 %). Para la congelación rápida, el tiempo fue de 100,56 ± 17,90 s (1,68 ± 0,29 min), siendo representado eficazmente por el modelo de Nagaoka (6,81 %). Las temperaturas de inicio de la congelación fueron, para la operación lenta y rápida, de -0,64 ± 0,02 °C y -2,91 ± 0,86 °C. Por medio de estos resultados, es posible obtener y validar correlaciones que permitan predecir efectivamente los tiempos de congelación de la pulpa de açaí fresca, al considerar los principales parámetros del proceso: geometría, temperatura del medio frio y composición del alimento.
Sparse Subspace Clustering in Hyperspectral Images using Incomplete Pixels
Authors: Bacca Jorge Luis , Arguello Henry
Published: November 2019

Spectral image clustering is an unsupervised classification method which identifies distributions of pixels using spectral information without requiring a previous training stage. The sparse subspace clustering-based methods (SSC) assume that hyperspectral images lie in the union of multiple low-dimensional subspaces.  Using this, SSC groups spectral signatures in different subspaces, expressing each spectral signature as a sparse linear combination of all pixels, ensuring that the non-zero elements belong to the same class. Although these methods have shown good accuracy for unsupervised classification of hyperspectral images, the computational complexity becomes intractable as the number of pixels increases, i.e. when the spatial dimension of the image is large. For this reason, this paper proposes to reduce the number of pixels to be classified in the hyperspectral image, and later, the clustering results for the missing pixels are obtained by exploiting the spatial information. Specifically, this work proposes two methodologies to remove the pixels, the first one is based on spatial blue noise distribution which reduces the probability to remove cluster of neighboring pixels, and the second is a sub-sampling procedure that eliminates every two contiguous pixels, preserving the spatial structure of the scene. The performance of the proposed spectral image clustering framework is evaluated in three datasets showing that a similar accuracy is obtained when up to 50% of the pixels are removed, in addition, it is up to 7.9 times faster compared to the classification of the data sets without incomplete pixels.

La modelación de la temperatura contribuye a la gestión de embalses, ya que es posible crear escenarios con diferentes condiciones para predecir su respuesta ante los cambios climáticos y los procesos de mezcla. Con este trabajo se busca aportar elementos de análisis del funcionamiento e identificación de los forzantes que dominan la dinámica térmica de un embalse tropical de montaña. Se registró la temperatura y el nivel de agua en tres sitios del embalse durante tres muestreos. Además, se midieron los caudales de entrada y salida al embalse y se analizaron los registros climáticos históricos. Con esta información se construyeron los archivos de entrada del modelo bidimensional CE QUAL-W2, para simular cuatro escenarios climáticos (seco, lluvia, transición y el fenómeno El Niño). De las afluencias se evidenció que la quebrada Santa Mónica en términos hidrodinámicos ejerce su efecto hasta el sitio de captación; de otro lado, la quebrada la Nitrera presenta recirculaciones verticales que aumentan el tiempo de residencia lo que tiene consecuencias en la calidad del agua para este sector del embalse. Los resultados de este ejercicio preliminar de modelación indican que el comportamiento térmico del embalse responde de manera diferenciada según el escenario climático y la magnitud de las extracciones. Durante el fenómeno El Niño y ante un incremento del agua captada, el embalse disminuye el nivel de agua en cerca de un metro y aumenta su temperatura alrededor de 3°C en la zona central del embalse. Ante la tendencia de crecimiento del municipio, se espera mayores demandas de agua que deberán ser suplidas por el embalse, por lo que toman importancia las herramientas de modelación que apoyen la gestión ambiental y reduzcan el riesgo al desabastecimiento ante la vulnerabilidad al cambio de climático.

Published: November 2019

Existen diferentes métodos que permiten establecer a escalas regionales la susceptibilidad a la ocurrencia de movimientos en masa. Entre los métodos más utilizados se encuentran los métodos estadísticos bivariado y multivariado, los cuales exigen un inventario de procesos de remoción en masa. En el presente estudio se evalúa y zonifica la susceptibilidad por movimientos en masa en el norte de los Andes colombianos, región conocida como valle de Aburrá, por dos métodos estadísticos, uno de ellos bivariado, denominado Peso de la Evidencia, y recomendado por el Servicio Geológico Colombiano para estudios de amenaza en suelos rurales; y un segundo método estadístico tipo multivariado, denominado Regresión Logística, de amplio uso a nivel mundial. Para ambos casos, la construcción del modelo de susceptibilidad se realizó soportado en el histograma de frecuencias, correlación de Pearson, Análisis Discriminante y Análisis de Componentes Principales. Para evaluar el desempeño, la capacidad de predicción y los criterios de zonificación en alto, medio y bajo de cada uno de los métodos utilizados se utilizó el análisis ROC. Para la regresión logística se obtuvo un área bajo la curva del 76.8 % para el desempeño y 77.5 % para la capacidad de predicción, mientras que para el Peso de la Evidencia se obtuvo un 77.8% en el desempeño y 77.5% en la predicción, señalando resultados satisfactorios que permiten la incorporación de dichos resultados en los estudios básicos necesarios para la ordenación del territorio.
