Precision Limits in Quantum Metrology with Open Quantum Systems
Authors: Haase J. F. , Smirne A. , Huelga S. F. , Kołodynski J. , Demkowicz-Dobrzanski R.
Published: October 2018

The laws of quantum mechanics allow to perform measurements whose precision supersedes results predicted by classical parameter estimation theory. That is, the precision bound imposed by the central limit theorem in the estimation of a broad class of parameters, like atomic frequencies in spectroscopy or external magnetic field in magnetometry, can be overcomewhen using quantum probes. Environmental noise, however, generally alters the ultimate precision that can be achieved in the estimation of an unknown parameter. This tutorial reviews recent theoretical work aimed at obtaining general precision bounds in the presence of an environment.We adopt a complementary approach,wherewe first analyze the problem within the general framework of describing the quantum systems in terms of quantum dynamical maps and then relate this abstract formalism to a microscopic description of the system’s dissipative time evolution.We will show that although some forms of noise do render quantum systems standard quantum limited, precision beyond classical bounds is still possible in the presence of different forms of local environmental fluctuations.
Effect Sizes for Paired Data Should Use the Change Score Variability Rather Than the Pre-test Variability
Authors: Dankel Scott J. , Loenneke Jeremy P.
Published: October 2018

Dankel, SJ and Loenneke, JP. Effect sizes for paired data should use the change score variability rather than the pre-test variability. J Strength Cond Res 35(6): 1773–1778, 2021—Effect sizes provide a universal statistic detailing the magnitude of an effect while removing the influence of the sample size. Effect sizes and statistical tests are closely related with the exception that the effect size illustrates the magnitude of an effect in SD units, whereas the test statistic illustrates the magnitude of effect in SE units. Avoiding statistical jargon, we illustrate why calculations of effect sizes on paired data within the sports and exercise science literature are repeatedly performed incorrectly using the variability of the study sample as opposed to the variability of the actual intervention. Statistics and examples are provided to illustrate why effect sizes are being calculated incorrectly. The calculation of effect sizes when examining paired data supports the results of the test statistic, but only when the effect size calculation is made relative to the variability of the intervention (i.e., the change score SD) because this is what is used for the calculation of the test statistic. Effect size calculations that are made on paired data should be made relative to the SD of the change score because this provides the information of the statistical test while removing the influence of the sample size. After all, we are interested in how variable the intervention is rather than how variable the sample population is. Effect size calculations that are made on pre-test/post-test designs should be calculated as the change score divided by the SD of the change score.

THIS ARTICLE INTRODUCES THE CONSTRUCT OF PHYSICAL LITERACY PARTICULARLY AS IT RELATES TO THE OLDER ADULT. MOST ARTICLES PERTAINING TO PHYSICAL LITERACY IN THE SCIENTIFIC LITERATURE HAVE SHARED INFORMATION RELATIVE TO THE SECTORS OF YOUTH SPORTS AND CHILDHOOD EDUCATION. HOWEVER, THE DEFINITION OF PHYSICAL LITERACY HIGHLIGHTS THE IMPORTANCE OF TAKING RESPONSIBILITY FOR ENGAGEMENT IN PHYSICAL ACTIVITIES FOR THE FULL LIFE SPAN. THEREFORE, THE FOCUS OF THIS ARTICLE IS ON THE OLDER ADULT, AN OFTEN OVERLOOKED AUDIENCE, AND ADDRESSES SPECIFIC SAMPLE EXERCISES THAT CAN HELP START THAT AUDIENCE ON THE PATH OF PHYSICAL LITERACY.

Published: October 2018

FOR DECADES, MOST SCIENTISTS AND PRACTITIONERS HAVE AGREED THAT MUSCLE HYPERTROPHY ALSO INDUCES STRENGTH GAINS. HOWEVER, A RECENT PUBLICATION “THE PROBLEM OF MUSCLE HYPERTROPHY: REVISITED,” BUCKNER, SL, DANKEL, SJ, MATTOCKS, KT, JESSEE, MB, MOUSER, JG, COUNTS, BR, ET AL. THE PROBLEM OF MUSCLE HYPERTROPHY: REVISITED. MUSCLE NERVE 54: 1012–1014, 2016, QUESTIONED THE MECHANISTIC ROLE THAT EXERCISE-INDUCED INCREASES IN MUSCLE SIZE HAVE ON THE EXERCISE-INDUCED INCREASES IN STRENGTH (OR FORCE PRODUCTION), AS WELL AS THE INFLUENCE THAT EXERCISE-INDUCED INCREASES IN STRENGTH HAVE ON SPORTS PERFORMANCE. SUCH SUGGESTIONS UNDERMINE THE IMPORTANCE OF CERTAIN ASPECTS OF STRENGTH AND CONDITIONING FOR SPORT. SPECIFICALLY, IF NOT ACTING AS A MECHANISM FOR STRENGTH ADAPTATION, IT IS UNCLEAR IF THERE IS A SPORTS-RELATED BENEFIT TO SKELETAL MUSCLE HYPERTROPHY. IN ADDITION, THE AUTHORS ARGUED THAT IF STRENGTH HAS LITTLE IMPACT ON SPORTS PERFORMANCE, STRENGTH AND CONDITIONING PROGRAMS MAY BE DOING LITTLE MORE THAN DELAYING RECOVERY FROM PRACTICING THE ACTUAL SPORT. THIS CONTENTION ALSO INDICATES THAT HYPERTROPHY SHOULD BE AVOIDED IN NEARLY ALL SCENARIOS BECAUSE INCREASED MUSCLE SIZE WOULD BE ADDITIONAL MASS THAT MUST BE OVERCOME. THE PURPOSE OF THIS SPECIAL DISCUSSION IS TO ALLOW FOR AN IN-DEPTH SCIENTIFIC DISCUSSION OF THE EXPERIMENTAL EVIDENCE FOR AND AGAINST THE POSITION OF BUCKNER ET AL. THAT EXERCISE-INDUCED INCREASES IN MUSCLE SIZE HAVE LITTLE RELEVANCE ON THE EXERCISE-INDUCED INCREASES IN STRENGTH, AND THUS, SPORT PERFORMANCE.
Examination of the Effects of Solids Content on Thickened Gold Mine Tailings Sedimentation and Self-Weight Consolidation
Authors: Bonin Michaël Demers , Cabral Alexandre R. , Nuth Mathieu
Published: October 2018

Thickening is being increasingly adopted by the mining industry because of its economic and environmental attributes, such as decreased amounts of water released following deposition and a smaller footprint of the tailings site. This study presents an assessment of the continuous process of sedimentation and the self-weight consolidation of slurry and thickened mine tailings. The results of a series of settling column tests performed with specimens with solids contents between 50 % and 72 % are presented and discussed. Lower solids contents that are more characteristic of slurry tailings were also included to cover a wide range of settling behavior. High-precision monitoring of pore water pressure was used to identify the transition from sedimentation to self-weight consolidation, which likely occurs between solids contents of 65 % and 68 % for this material, and it highlighted the fact that the combination of these two settlement processes accelerates ue dissipation. The displacement results for the tailings–water interface corroborate values in the technical literature related to the settlement of suspensions. Equilibrium was reached within a narrow time range (i.e., 400 to 500 min) despite the wide range of initial solids content in the slurries tested (i.e., 50 % S to 65 % S).
Soluble CD163 was linked to galectin-3, diabetic retinopathy and antidepressants in type 1 diabetes
Authors: Melin Eva O , Dereke Jonatan , Thunander Maria , Hillman Magnus
Published: October 2018

Objective

Depression has been associated with diabetic retinopathy and increased plasma levels of galectin-3, a lectin expressed in activated macrophages. Increased levels of sCD163, the soluble form of a macrophage expressed scavenger receptor involved in several inflammatory processes, have been demonstrated in the vitreous of the eye in type 1 diabetes (T1D) patients with severe diabetic retinopathy. The aim was to explore whether circulating sCD163 was associated with diabetic retinopathy, depression and/or galectin-3 in T1D patients, controlling for gender, metabolic factors, other diabetes complications, life style and medication.

Design

Cross sectional.

Methods

Two hundred eighty-seven T1D patients, men 56%, age 18–59 years, diabetes duration ≥1 year, were consecutively recruited from one specialist diabetes clinic. Depression was assessed by Hospital Anxiety and Depression Scale-Depression subscale. Blood samples, anthropometrics and blood pressure values were collected, supplemented with data from electronic medical records and the Swedish National Diabetes Registry. High plasma sCD163 was defined as ≥0.575 mg/L (corresponding to the 80th percentile) and high plasma galectin-3 as ≥4.659 µg/L (corresponding to the 95th percentile).

Results

The prevalence of depression was 10%, antidepressant medication 8%, diabetic retinopathy 72%, high sCD163 20% and high galectin 3 5%. High galectin-3 (AOR 9.7), antidepressants (AOR 3.8), diabetic retinopathy (AOR 2.4) and systolic blood pressure (per mmHg) (AOR 1.03) were associated with high sCD163.

Conclusions

This is the first study to show that circulating sCD163 was independently associated with galectin-3, the use of antidepressants and diabetic retinopathy, in patients with T1D. Depression was not associated with sCD163.
Evocando a PAULO FREIRE Trayectoria sócio-histórico-filosóficoideológica
Authors: Mendez Ginna
Published: October 2018

El presente artículo constituye un homenaje a la vida y obra del reconocido pedagogo brasileño Paulo Freire, así como una invitación a reencontrarnos con las contingencias históricas e influencias filosóficas que le llevaron a forjar una apuesta pedagógica, tal y como él mismo la caracterizara, eminentemente problematizadora, crítica y liberadora. De esta manera, reconociendo el elemento dialéctico que tuvo lugar entre la historia de vida, las fuentes filosóficas de las que se nutriera Freire y su proyecto emancipatorio y libertario que concibiera a través de la educación, nos proponemos dar cuenta de estos recorridos, los que a su vez esperamos constituyan una oportunidad para la re-contextualización y reinvención de la pedagogía crítica de Freire.

Published: October 2018

We present an inventory, followed by a consolidated list, for the avifauna of Estação Ecológica da Serra das Araras (EESA), state of Mato Grosso, Brazil. In our expeditions, we identified 287 species, 82% of them documented. Of these, 28 species are new records for EESA. Six are threatened, such as Lophornis gouldii (Lesson, 1832). Other noteworthy records include the first documentation of Oxyruncus cristatus Swainson, 1821, for Mato Grosso. The consolidated list includes 458 species, of which 255 were assigned to the primary list and 203 to the secondary list. The significant number of species compiled herein places EESA among the most species-rich protected areas of Brazil, especially in regard to areas not predominantly covered by forest. In terms of species composition, this is a community typical of an ecotone environment, featuring many species characteristic of the Cerrado and the Amazon and some of the Pantanal wetland.
Eulimids (Gastropoda, Eulimidae) on the Sea Cucumber Holothuria mexicana (Ludwig, 1875) (Holothuroidea, Holothuriidae) in Belize

Published: October 2018

This study presents new records for 4 eulimid species (Gastropoda, Eulimidae) including Melanella eburnea (Megerle von Mühlfeld, 1824), Melanella hypsela (Verrill & Bush, 1900), Melanella sp., and Eulimostraca encalada Espinosa, Ortea & Magaña, 2006 found on the body wall of the sea cucumber Holothuria mexicana in Belize. Three of these records (M. hypsela, M. eburnea, and E. encalada) represent a first for the Western Caribbean ecoregion and close a distributional gap for these species in the Caribbean. The geographic distribution of M. eburnea is thereby expanded by ~800 km; M. hypsela by ~1,200 km and E. encalada by ~970 km in the Tropical Northwestern Atlantic province. This article presents for the first time H. mexicana as a new host record for E. encalada.

Authors: Litwin Urszula , Budkowski Szczepan
Published: October 2018

The boundaries of land-records plots are shown in the real estate cadastre on the basis of documentation created as a result of geodetic and legal activities, connected with determining the
location of existing border points. The course of land plots’ boundaries should be considered in
the aspect of technological and legal space. This implies the need for an analysis of the problems
accompanying the implementation of standards for electronic data exchange (EDI) of land-register data, and the validation process in the context of the quality of these data. The example is
provided by two standards for the land records EDI: SWDE and GML.

Public participation in shaping the central space of the Jerzmanowice village located in the buffer zone of the Ojców National Park
Authors: Olczak Barbara , Nawrotek Magdalena
Published: October 2018

Suburban villages undergo dynamic transformations that significantly affect their spatial and social structure. Particular attention should be paid to those locations situated within an attractive
landscape, where investment pressure is gaining momentum. The threat of implementing new
functions at the expense of open areas increases with an attractive location in the vicinity of large
cities. The situation described herein concerns the Jerzmanowice-Przeginia municipality, which
is adjoining the Ojców National Park. The activities on the part of municipal authorities, aimed
at protecting the identity of the village, are conducted on two planes: related to land planning,
and to architecture. Students from the University of Agriculture were involved in the architectural scope of planning, and they developed concepts for the management of the central area of
Jerzmanowice village based on the results of social research carried out by the staff of the Faculty
of Biotechnology and Horticulture at the University of Agriculture in Kraków.
Influence of the city council towards model urban development
Authors: Pavliv Andriy
Published: October 2018

We examined post-industrial urban planning and problems of impulse development as well as
city management in the conditions of the information society, which turned out to be the most
urbanized in the history of mankind.
It was found that for specific conditions of a post-industrial city, the design of the impulse model
should consist of two stages – city-wide, and cluster-wide. Moreover, given the danger of hyper-urbanization, the first stage has to focus only on those factors that have a ‘transformative’
character, and those whose potential is mainly ‘inhabiting’ should be left behind. It should be
considered as an object of activity of city-wide institutions, applying such impulse factors as accessibility, favourability, self-sufficiency, and nobility.
This paper lists practical tasks of city-wide management institutions within the framework of the
universal impulse layer, which are derived from the universal factors of the spin-off development
of urban structures.
The role of knowledge transfer in the process of implementing new products by companies
Authors: Dąbkiewicz Marcin
Published: October 2018

The aim of the paper is to show the multi-faceted interactions occurring between the phenomenon of technology transfer and cooperation existing along the knowledge-business axis.
Research methods are the theoretical-empirical analysis, complemented with the study of subject literature, including reports and research done by the author. The study of the literature
proved the correctness of the hypothesis that the cooperation between scientific units and various businesses is determined by the transfer of knowledge, aimed at implementing innovative
solutions. Searching for facilitators and inhibitors in the process of knowledge transfer outside
the theoretical domain reveals an enormous practical dimension in updating economic programs, on both the domestic and international level.

This article was migrated. The article was marked as recommended. BackgroundThe Association of Faculties of Medicine of Canada, Future of Medical Education in Canada report shared a collective vision to improve social accountability, including a review of admissions policies to enhance student diversity. This study explored if and how the Medical College Admissions Test (MCAT) might mediate the socioeconomic diversity of Canadian medical schools by quantifying the costs and other cost-related factors of preparing for the exam.MethodsA 34-question anonymous and bilingual (English and French) online questionnaire was sent to the 2015 first-year cohort of Canadian medical students. Developed collaboratively, the survey content focused on MCAT preparation and completion activities, associated costs, and students' perceptions of MCAT costs.FindingsThe survey response rate was 32%. First-year medical students were more likely than the Canadian population to belong to high-income families (63% vs. 36%) and less likely to be from rural locations (4.5% vs. 19%). Use of MCAT preparation materials was reported by nearly every MCAT test-taker (95.3%): of those, 76.4% used free practice tests; 59.8% paid for practice tests; 45.1% registered for preparation courses; and 3.3% hired a private tutor. In terms of writing the MCAT, the total economic costs per respondent are estimated at $6,357 ($4,755-$7,958) and total direct costs per respondent are estimated at $2,970 ($1,882- $4,058). Opportunity costs represented the majority of economic costs, at $3,387 ($2,872 - $3,901), or 53.2%. MCAT preparation costs are estimated to be $2,372 ($1,373-$3,372), or 79.9% of total direct costs and 37.3% of economic costs. Most respondents agreed, 76%, that the MCAT posed a financial hardship.ConclusionThe financial demands of preparing for and completing the MCAT quantified in this study highlight an admissions requirement that is likely contributing to the current student diversity challenges in Canadian medical schools. In the spirit of social accountability, perhaps it is time to prioritize equitable alternative for assessing applicants' academic readiness for medical school.

O estudo teve como base, um mosaico em escala nominal aproximada de 1:10.000, produzido a partir de fotografias aéreas verticais do ano 2000, em escala nominal aproximada 1:30.000. Os resultados permitiram constatar que a pastagem foi a maior ocupação do solo, com 430,89 ha, correspondente a 65,21% da área estudada. Devido ao manejo inadequado do solo, é a cobertura vegetal que mais produz sedimentos por ocasião das chuvas, merecendo cuidados especiais para evitar os processos erosivos do solo. Foi constatado também, que os serviços de adequação e melhoria de estradas rurais, executados nas estradas municipais BRU-030 (antiga Bauru/Piratininga) e variante da BRU-030, atingiram seus objetivos, pois, praticamente, acabaram com a erosão das estradas, permitindo tráfego o ano inteiro, reduzindo o custo de manutenção das estradas e aumentando o abastecimento do lençol freático, além de outros benefícios.  UNITERMOS: ocupação do solo, erosão do solo, fotointerpretação.   PEREIRA, E.A., SOUSA, A. de P., CAMPOS, S.  LAND USE MAPPING IN SÃO JOSE AND ÁGUA DO VENTURA STREAMLET SUB-BASINS, BAURU (SP)   2 ABSTRACT  This work aimed the soil occupation mapping of São José and Água do Ventura streamlet sub-basins over the year 2000 and to verify how this occupation has been acting on sedimentation processes of streams and rivers. The study was based on a 1:10,000 nominal scale mosaic obtained from vertical aerial photographs in the year 2000 in a 1:30,000 approximate nominal scale. The results allowed to verify that pasture was the largest soil occupation, comprising 430.89 ha, corresponding to 65.21% of the whole area. Due to inappropriate soil usage, pasture has accounted for the major sediment production. It has also been verified that services for rural road suitability and improvement which were performed on BRU-030 municipal road (Bauru/Piratininga old road) and its branch have reached their objectives as erosion has been ceased leading to a better motor traffic all year long. Other benefits such as reduction of road servicing cost and rising of soil water table have also been observed.  KEYWORDS: soil occupation, soil erosion, photo interpretation.

Dessa forma, esta pesquisa objetivou avaliar a influência da lâmina requerida no desempenho desse sistema, para diferentes tipos de solo e comprimento de sulco. A análise de sensibilidade do desempenho foi desenvolvida mediante simulações do processo da irrigação por sulco, feitas pelo procedimento matemático hidrodinâmico do modelo SIRMOD (Surface Irrigation Simulation Model). Em todos os estudos de caso adotou-se a estratégia de manejo com vazão constante e a condição de irrigação adequada. As simulações foram realizadas em quatro tipos de solo, seis lâminas d’água e quatro comprimentos de sulco. Para os tipos de solo estudados observa-se que, no comprimento de sulcos de 100m, a eficiência de aplicação decresce à medida que a lâmina requerida aumenta, mas no sulco com comprimento de 250m ela aumenta sempre que a lâmina requerida também aumenta.  UNITERMOS: irrigação por sulcos, desempenho, lâmina requerida  AZEVEDO, C.A.V.; PORDEUS, R.V.; SILVEIRA, J.I.; LIMA, V.L.A.

INFLUENCE OF THE REQUIRED WATER DEPTH ON THE FURROW IRRIGATION PERFORMANCE  2 ABSTRACT  Considering the great using of the furrow irrigation system in Brazil as well as in most countries of the world, this research had the objective of evaluating the influence of the required water depth on the performance of that system, for different soil types and furrow lengths. The performance sensitivity analysis was developed through simulations of the furrow irrigation process performed by the hydrodynamic mathematical procedure of the SIRMOD model (Surface Irrigation Simulation Model). For all case studies, the continuous flow management strategy and the adequate irrigation condition were adopted. The studies were accomplished in four soil types, six required water depths and four furrow lengths. For the soil types studied, it is observed that in the 100m furrow length, theapplication efficiency decreases as the required water depth increases, but in the 250 m furrow length the application efficiency increases as the required water depth increases.  KEYWORDS: furrow irrigation, performance, required water depth

Para alcançar esse objetivo foi executada uma série de medidas nos rotores das bombas hidráulicas, uma metodologia de cálculo com base na teoria das bombas hidráulicas e em coeficientes experimentais fornecidos pela literatura especializada disponível. Os resultados obtidos permitiram verificar que um método simples, rápido e de baixo custo pode fornecer os valores nominais ou de projeto dos modelos de bombas avaliados. A conclusão do trabalho é que a metodologia proposta foi capaz de estimar os valores nominais da vazão Q0, da altura manométrica H0, da potência P0, do NPSH requerido NPSHr0, do rendimento Rg0 e da velocidade específica Nq0, a partir das medidas das características físicas dos rotores dos modelos de bombas estudados.  UNITERMOS: sistemas de bombeamento, irrigação, agricultura.   CALGARO, M., ROBAINA, A.

X.OPERATIONAL PERFORMANCE CURVES OF CENTRIFUGAL PUMPS DETERMINED FROM THE PHYSICAL CHARACTERISTICS OF THE IMPELLER I - NOMINAL VALUES   2 ABSTRACT   This work aimed to develop a methodology to determine the nominal values of the outflow, manometric height, output, required potency and required NPSH in the highest point of efficiency for several pump models, from the measurements of the physical characteristics of the rotors (d1, d2, b2, e2 and ß2). To reach this objective a series of measurements was done in the hydraulic pump rotors, the used calculation methodology was based on the hydraulic pump theory   and on experimental coefficients, which were supplied by the available specialized literature. The obtained results allowed to verify that a simple, fast, low cost method can supply either the nominal or project values of the evaluated pump models. This work concluded that the proposed methodology was capable of estimating the nominal values of the outflow Q0, the manometric height H0, the potency P0, the Net Positive Suction Head required NPSHr0, the output Rg0 and the specific speed Nq0 starting from measurements of the physical characteristics of the rotors of the studied pump models.  KEYWORDS: pump’s system, irrigation, agriculture.

Mossoró-RN  1 RESUMO  Na irrigação localizada a economia de água se tornou uma grande vantagem em relação aos outros métodos.  Esta economia de água deve-se, principalmente, ao fato deste método de irrigação umedecer somente parte do solo no qual se encontram as raízes da planta.  O cálculo da quantidade de água necessária a cultura, pode ser obtido indiretamente a partir do coeficiente de cobertura do solo, utilizando o coeficiente de redução.  O objetivo deste trabalho foi de estimar o coeficiente de cobertura para a cultura do melão para as condições do município de Mossoró – RN.  Na pesquisa, o ciclo da cultura foi subdividido em cinco fases, sendo o, coeficiente de cobertura estimado no final e no ponto médio de cada fase. Os resultados mostraram que o coeficiente de cobertura variou entre os valores de 2,40 e 80,50 % nos finais das fases inicial e de floração, respectivamente.  Aos 52 dias após o plantio,  o coeficiente de cobertura atingiu 100%, este ponto coincidiu com o ponto médio da fase de frutificação.  UNITERMOS: Irrigação localizada, desenvolvimento vegetativo e ciclo da cultura.  BEZERRA, J.

ESTIMATE OF COVERING COEFFICIENT FOR  MELON CULTURE  2 ABSTRACT  In localized irrigation water saving has become a great advantage in comparison to the other methods.  This water saving occurs mainly because this system causes partial wetting of the soil in the root zone.  Calculating how much water is necessary for the crop can be done indirectly using the reduction factor based on the crop ground cover. This paper aimed to estimate the ground cover coefficient for melon in Mossoró – RN.  In this study the melon growing cycle was divided into five development stages and the ground cover coefficient was estimated at the average and finals point of each stage.  The results showed that the covering coefficient varied between 2.40 and 8.50% in the end of the initial and flowering phases, respectively.  At 52 days after the melon planting, the ground cover coefficient reached 100%, which was the same one as the fructification stage.  KEYWORDS: drip irrigation, vegetative development and cycle of the culture.

CARACTERIZAÇÃO FÍSICO-HÍDRICA DE UM CONDICIONADOR DE SOLO E SEUS EFEITOS QUANDO MISTURADO A UM SUBSTRATO ORGÂNICO  Eliezer Santurbano Gervásio1;  José Antônio Frizzone21Instituto Centro de Ensino Tecnológico, Unidade Descentralizada de Sobral, Sobral, CE, esgervas@ig.com.br2Departamento de Engenharia Rural, Escola Superior de Agricultura “Luiz de Queiroz”, Universidade de São Paulo, Piracicaba, SP.  1 RESUMO              O propósito desse trabalho foi caracterizar as propriedades físico-hídricas de um condicionador de solo e verificar os seus efeitos quando misturado a um substrato orgânico. Foi utilizado o condicionador comercial TerraCottem®, o qual foi submetido a ensaios de absorção em água destilada, absorção em solução salina e reabsorção. Posteriormente, doses do condicionador (0; 2,5; 5; 7,5 e 10kg m-3) foram adicionadas a um substrato orgânico, o qual foi submetido a ensaios laboratoriais para a determinação da curva característica de retenção de água e condutividade hidráulica do substrato saturado. Os excelentes resultados obtidos em laboratório, principalmente em termos de absorção e reabsorção, não são os mesmos quando da utilização do condicionador misturado ao substrato, podendo inviabilizar a sua aplicação principalmente devido o seu elevado custo. Quando o objetivo é a retenção de água, a atividade dos polímeros hidroabsorventes fica reduzida quando adicionados ao substrato orgânico.  UNITERMOS: Condicionador, polímeros hidroabsorventes, substrato.  GERVÁSIO, E. S.; FRIZZONE, J. A. PHYSICO-HYDRIC CHARACTERIZATION OF A SOIL CONDITIONER AND ITS EFFECTS WHEN MIXED TO AN ORGANIC SUBSTRATE  2 ABSTRACT  The purpose of this work was to characterize the physico-hydric properties of a soil conditioner and verify its effects when mixed to an organic substrate. Commercial conditioner TerraCottem® was used, then submitted to absorption tests in distilled water, in saline solution and re-absorption. Afterwards, doses of the conditioner (0; 2.5; 5; 7.5 and 10kg m-3) were added to an organic substrate, which was submitted to laboratory tests to determine the characteristic water retention curve and hydraulic conductivity of the saturated substrate. The excellent results obtained in laboratory, mainly for absorption and re-absorption, are not the same ones when compared to the use of the conditioner mixed to an organic substrate, which might make its application impossible mainly due to its high cost. When the objective is water retention, the activity of hydro absorbent polymers is reduced if they are added to organic substrate.  KEYWORDS: Conditioner, hydro absorbent polymers, substrate

O cultivo de soja é uma opção economicamente viável para a ocupação dessas áreas em rotação e/ou em sucessão à orizicultura. Este trabalho foi realizado em casa de vegetação localizada em uma área experimental da ESALQ/USP, Piracicaba – SP, com o objetivo de avaliar os efeitos de rebaixamentos sucessivos do nível freático (NF) no desenvolvimento e na produtividade de plantas de soja, cv. BR-16, e identificar o estádio de desenvolvimento da cultura com maior sensibilidade à inundação do solo. O delineamento utilizado foi o inteiramente casualizado, em arranjo fatorial (2x5) com um tratamento adicional (testemunha), sendo os fatores estudados: período de desenvolvimento da cultura durante a inundação do solo (estádios V8 e R4) e rebaixamento do NF (10, 20, 30, 40 e 60 cm dia-1). As plantas de soja apresentaram maior suscetibilidade à inundação do solo durante o período vegetativo. As taxas de rebaixamento do NF influenciaram o desenvolvimento e a produtividade dessa cultura. O aumento da velocidade de drenagem reduziu os danos ocasionados às plantas pelo excesso de água no solo, principalmente no estádio menos tolerante a essa condição. UNITERMOS: inundação, coeficiente de drenagem.  SÁ, J.

SENSITIVITY OF SOYBEAN PLANTS TO WATER TABLE DRAWDOWN   2 ABSTRACT Agricultural diversification in low lands is very important in several Brazilian regions and countries, especially in irrigated rice lands. Soybean is a viable economic option for low lands. This study was carried out in an experimental area at ESALQ/USP, Piracicaba, São Paulo – Brazil. The objectives were to estimate the effects of water table drawdown in the growth and crop yield of soybean cv. BR-16 and to identify the most sensitive crop stages to soil water logging. The statistical experimental design was a completely randomized one with factorial arrangement (2x5) one additional treatment (control) and four replications. The study was done in the V8 e R4 crop stages. The water table was lowered 10, 20, 30, 40 and 60cm per day, from initial level. Control plants where only irrigated without flooding. The soybean plants showed highest susceptibility to soil water logging in the vegetative stage. The water table drawdown rates influenced the development and productivity of soybean plants. The drainage rate increase reduced the damage caused to the plants by the water excess in the soil, mainly in the less tolerant stage. KEYWORDS: flooding, drainage coefficient.
