Cultura de datos y mejora escolar: toma de decisiones educativas basadas en evidencias
Authors: González Acosta Melvis Lissety , Rodríguez Rodríguez Diana Isabel
Published: February 2020

La presente investigación tuvo como objetivo aprovechar el potencial del récord académico de los estudiantes para guiar la práctica docente al aumento del éxito educativo. Plantea como hipótesis que el análisis de la información contenida en el récord académico contribuye a transformar los procesos de enseñanza/aprendizaje, en cuatro niveles: descriptivo (qué ocurre); diagnóstico (por qué ocurre), predictivo (qué puede suceder) y prescriptivo (cómo se puede mejorar). Se trató de un estudio prospectivo en el cual se recolectaron datos históricos: notas de la asignatura de matemáticas del récord académico de un grupo de 15 estudiantes que han permanecido juntos durante cinco cursos escolares, en un periodo que va desde septiembre del año 2014 hasta julio del año 2019. Los resultados muestran que, en los primeros cinco años de estudio de las matemáticas, las calificaciones tienden a decrecer, y cuando se manifiesta un ascenso mínimo es por debajo del punto de partida. El bajo rendimiento académico a causa de las dificultades para el aprendizaje de la matemática está vinculado a posteriores deserciones en los primeros ciclos de la universidad, y constituye un problema actual de alcance nacional e internacional, que comparten un número considerable de instituciones educativas.

Authors: Jin Jie , Wu Xianming , Li Zhijun
Published: February 2020

An ultra low power mixer with out-of-band radio frequency (RF) energy harvesting suitable for the wireless sensors network (WSN) application is proposed in this paper. The presented mixer is able to harvest the out-of-band RF energy and keep it working in ultra low power condition and extend the battery life of the WSN. The mixer is designed and simulated with Global Foundries ’ 0.18 μ m CMOS RF process, and it operates at 2.4GHz industrial, scientific, and medical (ISM) band. The Cadence IC Design Tools post-layout simulation results demonstrate that the proposed mixer consumes 248 μ W from a 1V supply voltage. Furthermore, the power consumption can be reduced to 120.8 μ W by the out-of-band RF energy harvesting rectifier.
Dry magnetic separation technology for the recovery of iron minerals in fine-grained steel slag
Authors: Shi Liang Chang , Wang Nan Sheng , Cheng Gan
Published: February 2020

Using the MagNet software package, a permanent magnetic circuit was simulated and a sectorially-spliced magnetic system was designed. Consequently, a new roller permanent magnetic separator with different magnetic field intensities in each roller was developed. The modular structural design allows fine-grained minerals with different magnetic susceptibility to be separated in one pass, according to their different
processing characteristic. Steel slag, selected from a factory, was crushed, ground and sieved into different particle size ranges for the single-factor magnetic separation experiments. It was determined that the optimum value ranges for the particle size, magnetic separation distance and rotating frequency were 0.15 mm-0.3 mm, 10 mm-12 mm, 40 Hz～60Hz, respectively; using the chosen parameter values of 0.2mm, 11mm,
and 40Hz, the concentrate recovery and concentrate grade of the new separation technology reached up to 52.78% and 64.74%, in comparisson with the existing technology. Thus, it was demonstrated that the self-developed separation technology has the potential to improve the iron recovery of the fine-grained steel slag.

Published: February 2020

This work has as an objective a study of evolution of characteristic properties of crystalline microstructure and mechanical hardening of aluminum by iron oxide (III), (hematite α-Fe2O3) nan energetic material known as thermite, samples of massive alloys, Al (base)-X wt% Fe2O3 (X =2, 4, 16 and 40) were studied.Al-Fe2O3 composite was developed by a sintering technique from the mixtures of compacted powders of Al high purity and α-Fe2O3 under a temperature of 700 °C for 1 hour and then slowly cooled. We have not noted the formation of thermite as foreseen by the chemical reaction due to the mixture of aluminum with hematite. The evolution of crystalline microstructures and the morphologies of surface were determined by means of X-ray diffraction, thermal analysis and optical metallography. The mechanical behavior was characterized by the tests of Vickers indentation and corrosion resistance by electrochemical tests.
Energy transformation without using filter on high resistive load
Authors: Can Erol
Published: February 2020

In this paper, 9-level, 17-level, 19-level, 21-level, 27-level, and 39- level inverters with SPWM are presented. According to a switching function, the high-multilevel inverter design has been described since a
new multi-level inverter structure is considered. The multilevel inverter structure is designed with placing switches and sources on levels. Pulse width modulation, controlling switches in the inverter structure, is also produced by comparison between triangles and sinus signals. Operating sequences of the switches are given in the table in order to demonstrate the inverter operation characteristic with the produced signals. Then, mathematical equations are formed by considering
an operation of switches on the load. In simulations and experiments, the 9-level, 17- level, 19-level, 21-level, 27-level, and 39-level inverters are performed on the resistance (R) and inductance (L) loads with different resistance, because it is difficult to generate current and voltage with an acceptable harmonic distortion on the impedances which have high ohmic values. After applications of experimentation and simulation, the obtained results are compared with other published papers of results and the international IEEE standard, which is 5% for harmonic distortions of creating currents and voltages.

Published: February 2020

Gneisses and granites mechanical properties knowledge such as the Los Angeles and Micro-Deval coefficients is very important for the engineer when designing and building civil engineering works. Laboratories test often performed to obtain Los Angeles and Micro-Deval values are expensive and time consuming. For this, the depths (parallel and perpendicular to the foliation planes) obtained during a rock drilling test will be used to estimate its coefficients Los Angeles and Micro-Deval. In this study, an ANFIS approach is used to estimate gneisses and granites Los Angeles and Micro-Deval that have been compared to the Multiple Linear Regression method. For this purpose, we have used a database of a sample size of 80 to determine the parameters of the ANFIS and Multiple Linear Regression models, and a second sample of size 15 used for the validation tests. The results obtained show us that we can estimate the mechanical properties (Los Angeles and Micro-Deval) of gneisses and granites with ANFIS approach.
El pasado es una puesta en escena: posmemoria e identidad en el documental y la ficción televisiva española actual
Authors: Gómez Iván
Published: February 2020

La relación entre memoria histórica y personal siempre ha sido un tema controvertido y poco pacífico. Historiadores, narratólogos e incluso neurobiólogos discuten sobre la mejor manera de acceder al traumático pasado que suponen hechos como la Guerra Civil o la posterior dictadura franquista en España. La producción documental audiovisual sobre esos años ha experimentado un auge en los últimos tiempos, fruto tanto de un interés por recuperar la memoria de los cada vez más mayores supervivientes, como de un legítimo intento por reescribir capítulos que algunos pretendían cerrados para siempre, cuando no directamente olvidados. La necesidad de fijar testimonios y sistematizarlos antes de que los protagonistas fallezcan ha animado proyectos muy diversos, acometidos en ocasiones por familiares directos de los protagonistas históricos. Nos referimos a productos como El muro de los olvidados (Joseph Gordillo, 2008), en donde el director francés trata de encontrar los restos de su abuelo, un maquis fusilado por la Guardia Civil en 1946; pero también a películas como Nadar (Carla Subirana, 2008), Pepe el andaluz (Alejandro Alvarado, Concha Barquero, 2012) o el cortometraje “Haciendo memoria” (Sandra Ruesga, 2005), integrado dentro del documental colectivo Entre el dictador y yo (2005). Estos productos establecen un modelo comparable con otros casos, como el argentino o el chileno, que han generado filmes muy similares. El objetivo del artículo es analizar los mecanismos de puesta en escena que utilizan estos documentales para averiguar en qué medida dichos recursos fílmicos refuerzan o desvirtúan, recuperan o inventan, según sea el caso, un pasado (in)accesible. Someteremos las películas a un análisis a partir de los conceptos sobre narración y autoficción, posmemoria, trauma e identidad. Pulsar el estado de la última producción documental española nos permitirá también reflexionar sobre los procesos de mediatización del pasado, siempre afectado por los rigores e inexactitudes de la memoria personal y por el filtro que impone el dispositivo fílmico.

The decrease in fertility of highly productive dairy cows associated with postpartum ovarian depression is becoming one of the significant problems of modern dairy cattle breeding. The aim of this study was to identify and assess the state of protein, carbohydrate and lipid metabolism in Holstein-Friesian cows in the dynamics of postpartum period with the restoration and depression of ovarian ovulatory function against the background of their adequate feeding. The experiment included 16 fresh cows with an average annual dairy productivity of 9.5 ths kg. The blood for the study was obtained from the caudal vein on the 6th, 12th, 40th and 68th days after calving. Blood serum content of total protein and its fractions, urea, creatinine, total lipids, cholesterol, triglycerides and glucose was determined. The state of genitals was evaluated by transrectal palpation and ultrasound scanning, as well as by blood concentration of progesterone and estradiol. It has been shown that the formation of postpartum ovarian dysfunction in cows occurs against the background of low blood content of glucose, globulin protein fractions and increased creatinine content. The threshold serum concentration of glucose during the first two weeks after calving, at which ovarian dysfunction and a decrease in animal fertility should be predicted, is less than 2,2 mmol/L. There was expressed a judgment on the appropriateness of further researches to identify the relationship of the metabolic status of animals with the typological features of their higher nervous activity.

Published: February 2020

The article presents the analysis of materials of the primary zootechnical accounting and also the results of own researches of cows reproductive ability by year seasons on the dairy farms of Primorye and Priamurye. The analysis of the primary zootechnical accounting for the last five years detected the significant difference in calving quantity by year seasons. 46,2 % of cows from 4460 cows calved in spring, 11,7 % - in summer. In the same time the inter-seasons differences turned out to be less significant on the farms with year-round stable maintenance. For a number of years, the influence of individual meteorogical factors (temperature, air moisture, atmospheric pressure, sun activity, sunshine duration, magnetic storms) has been studied. The part of air temperature influence and air moisture varied from 0,02 to 0,09; atmospheric pressure – from 0,01 to 0,11; sunshine duration – from 0,05 to 0,33. The results of different years of observations are practically the same, and they indicate the weak influence of these factors, spontaneous display of cows wish in the pasture. The prolongivity of the sunshine is exception. The higher means of the factorial dispersion were received when using the monthly average means of weather during the pasturable period, but not when using the average daily or average day (morning, afternoon, evening) means. The calculations showed, that the higher the temperature, the worse the cow fertility. During seven summer seasons in different years on dairy farms with different levels of cow productivity, the effect of the standard extract of Eleutherococcus senticosus roots on fertility in the summer heat was studied. Average for all years of the experiment the fertility became higher on 15,68 %.(P< 0,001,td=4,9).
The genus Trochodendroides Berry in the cretaceous floras of Siberia
Authors: Golovneva L. B. , Alekseev P. I.
Published: February 2020

Seventeen species of the genus Trochodendroides and one species of the genus Nyssidium are described from the Albian-Maastrichtian deposits of the Chulym-Yenisei depression (Western Siberia), Lena-Vilyui depression (Eastern Siberia) and Kolyma River basin. The study of recently collected materials and revision of previous data allow us to describe 4 new species (T. buorensis Golovn., sp. nov, T. beketovii Golovn., sp. nov., T. rostrata Golovn. et P. Alekseev, sp. nov.) and to offer 6 new combinations (T. tiungensis (Budants.) Golovn., comb. nov., T. heterophylla (Budants.) Golovn., comb. nov., T. kemensis (Ananjev) Golovn., comb. nov., T. sibirica (Tcherepnin) P. Alekseev, comb. nov., T. bajkovskae (I. Lebed.) Golovn., comb. nov., T. gromovii (E. Lebed.) Golovn., comb. nov). The new names were proposed for two species (T. budantsevii Golovn., nom. nov., T. ananjevii Golovn., nom. nov.). The morphological diversity, variability and value of different characters for distinction of species are discussed. The epidermal features were firstly examined for T. heterophylla and T. ananjevii. They are mostly similar to epidermal features of Cercidiphyllum. The genus Trochendroides firstly appeared in Siberia in the early-middle Albian as a minor component of the conifer-dominated Mesophytic floras. The determination of this genus is verified by the findings of Nyssidium fruits. During the Late Cretaceous the genus Trochodendroides was common member in floras of the Siberian-Canadian phythogeographic region. The systematic and morphology diversity of Trochodendroides was comparatively low in the late Albian–Cenomanian and the findings of these leaves are rare. The abundance of Trochodendroides leaves was increased in the Turonian and the Coniacian. During the Coniacian this genus reached the highest systematic and morphologic diversity (the Antibes and the Vilyui floras). In the Santonian-Campanian the abundance of Trochodendroides leaves was decreasing again. In this time the lanceolate or narrow-ovate leaf morphotypes were most usual. They were often described as Macclintockia, Zizyphus or Paliurus. Genus Trochodendroides is not presented in the Cretaceous deposits of Europe and firstly appeared there in the Tertiary. This genus is rare in the Late Cretaceous deposits of the Turan province, near the boundary between Siberian-Canadian and Euro-Sinian phythogeographic regions.

Published: February 2020

At present the ruderal vegetation of Salavat town (Baschkortostan Republic) (classes Polygono arenastri–Poёtea annuae, Galio-Urticetea and Robinietea) is presented by 4 associations, 2 subassociations, 2 communities of 4 alliances (1 derivate and 1 basal) belonging to 3 orders. The plant coenosis of the class Polygono arenastri–Poёtea annuae have the greatest distribution among the considered vegetation classes. They are most actively developed n an urban environment due to continuous existence of a trampling factor. Coenosis of the class Galio-Urticetea occupy small patches I which is connected with geographical position of the studied town. It a fact that the greatest variety of communities of the class Galio-Urticetea is connected with natural forests. However these forests are not many in the town and the forest vegetation is presented mainly by artificial plantations (particularly the plant communities of the class Robinietea).

Islamic bank’s mudarabah contract customers. The injustice is on the nisbah or
ratio between the capital owner and the capital manager. There ara model or
proposal to how to determine the profit sharing ratio, however, there is still

This research, using an explorative and qualitative approach contributes to the
philosophical basis in determining the just profit sharing ratio. The reason
for the research is since justice is one of the Islamic economy pillars in
Islamic economy paradigm. By this research, it is hoped that the future
practice of profit sharing ratio will be just for the actors of the Muḍārabah contract.
Language Ideology in Cross-Cultural Communication
Authors: Yanka Amelia , Rex Ed
Published: February 2020

According to Franz Boas, the socio-cultural context within which a speech community thrives and upon which its collective preferences and linguistic prejudices are established should be considered only as a "secondary rationalization" and should be relegated below the more important aspect of studying the inherent dynamics of the language itself. In the process, Boas developed an alternative linguistic model where race, language, and culture may be separated from-and can function independently of-each other. This model allows an external observer to develop a keen understanding of any given language without the need to solicit value-laden information-such as cultural, religious, or social judgments-from native speakers. Thus, secondary rationalizations, while important, may be bypassed in any attempt of a non-native linguist to understand and reconstruct a given language
Biofluid choking a paradigm shift in the diagnostic sciences of stroke - Blood pressure ratio and heat capacity ratio are the risk factors for hemorrhage and heart attack
Authors: V R SANALKUMAR
Published: February 2020

Author reported conclusively through the state-of-the-art closed-form analytical methodology that the stroke and the transient-ischemic-attack could occur due to the boundary-layer induced blockage at the transition region while attaining the biofluid choking condition without any iota of symptom of plaque formation in the arteries particularly with bifurcation regions. At the biofluid choking condition, the systolic-to-diastolic blood pressure ratio (BPR) is a unique function of the blood/biofluid heat capacity ratio (BHCR). The biofluid flow choking occurs when the blood/biofluid velocity in the blockage region (boundary-layer and/or plaque-induced blockage) is equal to the local velocity of sound. Biofluid choking is more susceptible during winter due to an enhanced blood viscosity. Sanal flow choking creates cavitation and shock waves leading to pressure-overshoot causing stroke and/or Spontaneous coronary artery dissection (SCAD). The SCAD is more severe for the vessels with high-relaxation modulus as a result of the memory effect (stroke history) carried over the years due to choking and unchoking phenomena due to the fluctuating BPR. While using the blood-thinners and/or drugs with anticoagulant properties the dynamic viscosity of blood decreases and as a result Reynolds number increases and the laminar flow could be disrupted and become turbulent and thereby the boundary-layer-blockage factor increases leading to an early biofluid choking, cavitation and shock wave generation. The author concluded that suppressing the turbulence level and simultaneously reducing the blood viscosity are the key tasks to prevent heart attack and stroke, which could be achieved through a single-medicine or a companion-medicine, with traditional-anticoagulants-drugs, capable to increase the BHCR or decrease the BPR. The author also concluded through an analytical model that the stents could reduce the risk of MI but no better than drugs owing to the fact the biofluid choking could occur with and without stent.
Moderators of Career Calling and Job-Search Behaviors among Unemployed Individuals
Authors: Dalla Rosa Anna , Vianello Michelangelo , Galliani Elisa Maria , Duffy Ryan D.
Published: February 2020

We examined the relationship between calling, job-search clarity, and job-search intensity in a cross-sectional study of Italian unemployed job seekers (N = 315). Structural equation modeling with observed variables and latent moderated structural equation models were adopted to test whether optimism, self-esteem, and perseverance moderate the relation between calling, job-search clarity and job-search intensity. Perceiving a calling was positively related with job-search clarity and intensity and these relations were stronger in individuals with lower levels of optimism, self-esteem, and perseverance. This study suggests that perceiving a calling is an important personal resource that is related to a clearer job-search goal, more intense job-search activities and can support job seekers in personal adverse condition. These results suggest integrating job-search behaviors in the Work as Calling Theory and that incorporating the construct of calling into career counselors’ practices may increase the efficacy of job-search activities.

Plants on the road landscape have various uses, both architectural, functional, ecological and aesthetic aspects. Functional means it can be used optimally and aesthetically and can be interpreted as something beautiful. In terms of aesthetics, trees can be enjoyed in terms of shape, color, aroma, texture, roots, stems, leaves, flowers and fruit that can provide spiritual satisfaction to humans. The purpose of this study is to identify and evaluate the shape and function of trees, using survey methods with quantitative parameters namely pollution reduction, noise reduction and physical barriers. The parameters are adjusted to the citeria for road landscape plant functions as determined by the Department of Public Works of the Directorate Generalof Highways (1996). The presence of plants on the Green Lane landscape of the Veterans Road has important significance in relation to security, safety and comfort of road users and the sustainability of the surrounding environment Based on the results of the evaluation conducted, it can be concluded that the quantity and quality of plants on the site from the aspect of its function as a pollution reduction, noise reduction and room divider and aesthetic aspects have not fully met the criteria. Pollution reducing parameters, on the East side 73.8%; Middle Park 86.46%; and West 75.36%, with good to very good levels.

Study on the virus transmission based on data analysis of confirmed cases of 2019-nCoV coronavirus in China (II)
Authors: Chen Peng
Published: February 2020

This study is the continue work of the first analysis result posted in 31 Jan (https://doi.org/10.31219/osf.io/ek9n4).[1] This study was also based on the numerical analysis and general system evolution principle to analyze the number of confirmed cases and related data of 2019-nCoV coronavirus in China from 31 January to present (4 February) announced by the National Health Commission. The analysis result shows that during this period, the number of confirmed cases increased roughly according to a linear growth, the turning point is on 30 Jan. The main conclusion is that the spread of the virus has been effectively restricted since 23 Jan in most region of China, that is, since Wuhan city and many other cities were put on lockdown. The lockdown strategy shows the power equivalent to near 80% of the people infected with the virus being captured by hospitals or isolated at home in the statistical equivalent. Based on these results, the spread of the virus can be expected to be slowdown due to the harsh lockdown strategy that leads to a slow decrease of the number of people who have not been diagnosed. It is suggested to maintain the lockdown strategy, especially in Hubei province, continue to concentrate the study on 2019-nCoV coronavirus transmission mechanism and then take targeted measures to comprehensively stop the virus infection.
Maskless exposure device for photolithography
Authors: Rajan Dhanesh Kattipparambil
Published: February 2020

Photolithography plays a consequential role in transferring patterns from photomasks to substrates and thereby is an important tool in semiconductor, IC, MEMS and many microstructures’ production. The photomasks are preprinted prior to the photolithographic procedure with certain layouts, and these layouts are transferred to surfaces of materials like silicon during the lithography and finally these surfaces undergo chemical processes by which three dimensional micro features are formed. Therefore photomasks containing specific layouts are the inevitable components in the entire procedure, but unfortunately those are expensive in its nature together with time consuming production formalities. Some of the successful attempts to remove these difficulties are cost effective photomasks and maskless lithography.A system named ‘Maskless Exposure Device’ (MED) is introduced here as my thesis related research and it is intended to replace the expensive photomasks. The device transfers images and layouts created on a computer, easily and effortlessly to different substrate surfaces and can be repeatedly used in photolithography by introducing new drawings on the computer screen and thereby, MED is nothing but a maskless lithographic technique.The device can be mainly used in research and development applications in MEMS production, microfluidic systems, semiconductor and biosensor designs, patterning of cell culture substrates, electrode structures etc. Research on design of microsensors and microactuators could be confronted extremely cost effectively with maximum time saving considerations.
A unified test of cognitive impulsivity reveals novel relationships with trait impulsivity and real world impulsive behaviour
Authors: Verdejo-Garcia Antonio , Tiego Jeggan , Kakoschke Naomi , Moskovsky Neda , Voigt Katharina , Lubman Dan I , Bellgrove Mark
Published: February 2020

Impulsive behaviours are a major contributor to global burden of disease. Recent research has criticised measures of cognitive impulsivity for poor reliability and inability to predict real-world behaviours. We address this concern via the development of the Cognitive Impulsivity Suite (CIS), comprising three computerised/online tasks delivered within a harmonised gamified interface. We conceptualise impulsive behaviour as arising from the failure of three distinct mechanisms: attentional control, information gathering, and shifting. Utilising the CIS, we aimed to examine: (1) construct and criterion-related validity in an online sample (N = 1056), (2) test-retest reliability and between-subjects variability in a face-to-face sample (n = 63). Results supported the theoretical architecture of the attentional control, information gathering, and shifting constructs. The three factors were differentially associated with trait-impulsivity facets, and the strength of these associations were substantially higher than previously reported. Furthermore, the CIS demonstrated incremental criterion-related validity for prediction of real-world, addiction-related problems.

The internet allows people to connect with virtually anyone across the globe, building communities based on shared interests, experiences, and goals. Despite the potential for furthering our understanding of communities more generally through exploring them in online contexts, online communities have not generally been a focus of community psychologists. A conceptual, state-of-the-art review of eight major community psychology journals revealed 23 descriptive or empirical articles concerning online communities have been published in the past 20 years. These articles are primarily descriptive and can be organized into four categories: community building and maintenance (seven articles, 30.43%), community support (six articles, 26.09%), norms and attitudes (six articles, 26.09%), and advocacy (four articles, 17.39%). These articles reflect a promising start to understanding how we can utilize the internet to build and enhance communities. They also indicate how much further we have to go, both in understanding online communities and certain concepts regarding community psychology more generally. Community psychologists involved in practice and applied settings specifically may benefit from understanding online communities as they become integral components of advocacy, community organizing, and everyday life.
Grouping mechanisms in numerosity perception

Enumeration of a dot array is faster and easier if the items form recognizable subgroups. This phenomenon, which has been termed groupitizing, appears in children after one year of formal education and correlates with arithmetic abilities. We formulated and tested the hypothesis that groupitizing reflects an ability to sidestep counting by using arithmetic shortcuts, for instance using the grouping structure to add or multiply rather than just count. Three groups of students with different levels of familiarity with mathematics were asked to name the numerosity of sets of 1-15 dots in various arrangements, for instance 9 represented as a single group of 9 items, three distinct groups of 2, 3, and 4 items (affording addition 2+3+4), or three identical groups of 3 items (affording multiplication 3x3). Grouping systematically improved enumeration performance, regardless of whether the items were grouped spatially or by color alone, but only when an array was divided into subgroups with the same number of items. Response times and error patterns supported the hypothesis of a multiplication process. Our results demonstrate that even a simple enumeration task implicitly involves mental arithmetic.

At present there are still many government offices, especially the tourism and cultural offices of the Thousand Islands, which do not utilize technology for employee attendance, resulting in frequent manipulation of attendance data. Manual presence can cause the tourism office to have to manually record a large amount of attendance data, and make the process ineffective and inefficient. Therefore, this study aims to discuss the Employee Presence System Design with IoT (Internet of Things) Based RFID Using NodeMCU ESP8266. So this research can facilitate the Department of Tourism for the present system of attendance for employees to be more effective and efficient and does not take much time. This system is integrated with the website so that when the employee makes a presence, the data is automatically saved directly into the website database. Database processing on websites using MySQL with the PHP programming language. From several tests, many types of cards can be read by RFID Reader, because these

O objetivo do trabalho foi verificar as características físicas e conservacionistas da bacia hidrográfica do Rio Santa Helena com o uso do sensoriamento remoto e geoprocessamento, e criar um modelo empírico de vulnerabilidade a erosão para a região. Foram realizadas as análises da densidade de drenagens, área total, perímetro total, coeficiente de compacidade, fator de forma, índice de circularidade, padrão de drenagem, comprimento do curso d´água principal, comprimento total dos cursos d´água e ordem dos cursos d´água. Para a criação do modelo de vulnerabilidade à erosão foi realizada a classificação supervisionada através do algoritmo de máxima verossimilhança, o cálculo do potencial erosivo das chuvas para a região, além da análise da declividade e do tipo de solo. Os resultados obtidos foram: área de drenagem 1461,68 km²; perímetro 329,16 km; comprimento axial 68,81 km; coeficiente de compacidade 2,41; fator de forma 0,31 e o índice de circularidade 0,17. A hidrografia apresenta padrão dendrítico, de 5ª ordem e com densidade de drenagem baixa (0,96 km/km²). Esses dados indicam um formato irregular e alongado da bacia. Quanto ao potencial erosivo, a bacia apresenta de baixo a médio risco, principalmente devido à declividade e à cobertura do solo.Palavras-chave: manejo de bacias hidrográficas; geoprocessamento; modelagem erosiva. PHYSICAL AND CONSERVATIONAL ATRIBUTES OF THE SANTA HELENA RIVER WATER BASIN ABSTRACT: The objective of this work was to verify the physical and conservation characteristics of the Santa Helena River basin using remote sensing and geoprocessing, and to create an empirical model of erosion vulnerability for the region. Drainage density, total area, total perimeter, compactness coefficient, shape factor, circularity index, drainage pattern, length of main watercourse, total length of watercourses and order of watercourses were analyzed. For the creation of the erosion vulnerability model, the supervised classification was performed through the maximum likelihood algorithm, the rainfall erosive potential calculation for the region, as well as the slope and soil type analysis. The results obtained were: drainage area 1461.68 km²; perimeter 329.16 km; axial length 68.81 km; compactness coefficient 2.41; form factor 0.31 and circularity index 0.17. The hydrography has a dendritic pattern of 5th order and low drainage density (0.96 km / km²). These data indicate an irregular and elongated shape of the basin. As for the erosive potential, the basin presents low to medium risk, mainly due to the slope and the ground cover.Keywords: management of watersheds; geoprocessing; erosive modeling.
