title: IRRIGAMETER USE FOR ESTIMATING CROP EVAPOTRANSPIRATION IN PROTECTED ENVIRONMENT

description: ABSTRACT In the face of climatic adversities associated with water lacking for irrigation, crop cultivation in greenhouses in Brazil has increased significantly, thereby demanding research that makes it possible to estimate crop water demand when grown in these environments. Therefore, the objective of this study was to evaluate the performance of Irrigameters to estimate the evapotranspiration of cowpea grown in protected environment. The experiment was conducted in the experimental area of the State University of Southwest of Bahia (UESB) under protected environment and the cowpea variety used was BRS Guariba. For this study, two Irrigameters were installed for the direct estimation of the daily crop evapotranspiration. Likewise, with the use of an automatic weather, the meteorological data were collected and the crop evapotranspiration (ETc) was estimated using the Kc values recommended for different phases of the crop. The data collected by the Irrigameter were compared with the data estimated by the Penman-Monteith method, as well as with Radiation and Blaney Criddle methods at one-, two- and three-day intervals. The results show that all the methods were efficient and accurate at estimating ETc at all studied intervals.

title: ENRICHMENT AND BIOAVAILABILITY OF TOXIC ELEMENTS IN INTENSIVE VEGETABLE PRODUCTION AREAS1

description: ABSTRACT Vegetable cultivation stands out for intensive use of agricultural inputs due to high nutritional requirements of plants within a short period and their high susceptibility to pests and diseases. This study aimed to identify the main factors responsible for changes in pseudo-total and bioavailable contents of Cd, Cu, Cr, Mn, Ni, Pb, and Zn in soils under intensive vegetable cultivation. Soil samples were collected from 146 sites in Petrópolis (RJ), Brazil, in 2017. The samples were collected at a depth of 0-20 cm in family farm systems during vegetable production period. Pseudo-total contents of toxic elements were determined by the EPA 3050B method. Geochemical fractionation procedure was used based on the BCR method. Pollution indices were also calculated. In general, vegetable producing areas presented low contamination by Cu, Zn, Pb, Mn, and Ni, except for Cd, which showed severe contamination. In areas with the lowest slopes, most of the toxic elements showed increasing contents, reflecting relief influence. Overall, inadequate soil management, intensive application of phosphate, potassium, and organic fertilization, and relief were the most influencing parameters on the enrichment and bioavailability of toxic elements in the soil.

title: Attributes that characterize a megalopolis

description: Abstract This work aims to define the specific attributes of a megalopolis. The study is qualitative and used discussion groups with 19 specialists who worked according to the interdisciplinary methodological perspective proposed by Delich. Data were collected, tabulated and analyzed according to the Method for Assigning Characteristics to Object (MACO), inspired by the method of Kano. This technique allows defining whether a certain characteristic belongs to a specific object or not. In the study, the object is the megalopolis. The results show that, considering the specific and important attributes, there are basically 20 attributes that must be taken into account. However, there are five specific attributes (the most important) that need recognition in megalopolis: strong adherence, integrated concentration of people, activities and wealth. This result allows the effectively recognition of whether an urban agglomeration is or is not a megalopolis.

title: Intermontane eolian sand sheet development, Upper Tulum Valley, central-western Argentina

description: ABSTRACTThe intermontane Upper Tulum eolian sand sheet covers an area of ca. 125 km² at north of the San Juan Province, central-western Argentina. The sand sheet is currently an aggrading system where vegetation cover, surface cementation and periodic flooding withhold the development of dunes with slipfaces. The sand sheet surface is divided into three parts according to the distribution of sedimentary features, which reflects the variation in sediment budget, water table level and periodic flooding. The central sand sheet part is the main area of eolian deposition and is largely stabilized by vegetation. The sedimentary succession is 4 m thick and records the vertical interbedding of eolian and subaqueous deposits, which have been deposited for at least 3.6 ky with sedimentation rates of 86.1 cm/ky. The construction of the sand sheet is associated with deflation of the sand-graded debris sourced by San Juan alluvial fan, which is available mainly in drier fall-winter months where water table is lower and wind speeds are periodically above the threshold velocity for sand transport. The accumulation of sedimentary bodies occurs in a stabilized eolian system where vegetation cover, thin mud veneers and surface cementation are the main agents in promoting accumulation. The preservation of the sand sheet accumulations is enabled by the progressive creation of the accommodation space in a tectonically active basin and the continuous burial of geological bodies favored by high rates of sedimentation.

title: The role of L1 English speakers’ familiarity with Brazilian-accented English (L2) in the intelligibility of Brazilian learners of English (L2): a discussion on intelligibility from a Complex Dynamic Systems perspective

description: Abstract The aim of this study is to investigate the effect of familiarity with Brazilian-accented English (L2) in the intelligibility of speech samples when judged by native English listeners. Speech samples were collected from five native Brazilian Portuguese individuals from Southern Brazil, with a pre-intermediate level of proficiency in English. Following a Complex Dynamic Systems account (De Bot et al., 2007), this is a longitudinal study in which a group of four British listeners participated in weekly intelligibility transcription tasks, administered over the course of five weeks. This group was comprised of individuals who had recently arrived in Brazil. Results suggest that familiarity with a speaker’s L1 and accented-L2 has an effect on the intelligibility of what is heard. From the perspective of Complex Dynamic Systems, we argue that there is an alteration of a listener’s perception of his/her own language system due to exposure to it as an L2.

title: Collaborative study to evaluate the mineral content in feeds

description: SUMMARY The objective was to conduct a collaborative study to evaluate the mineral matter contents in feeds in seven feed analysis laboratories from institutions linked to the National Institute of Science and Technology in Animal Science (INCT-CA). Six feeds were evaluated: signal grass hey, sugarcane, corn silage, soybean meal, corn grain and citrus pulp. It was asked to each laboratory that the samples were analyzed for six days, consecutive or not, with three replicates per sample per day of evaluation. Variations were observed among laboratories, days of analysis and interaction effect of material and laboratory. The variation of results among laboratories accounted from 33.5 to 78.2% of the total random variation. It was verified that the repeatability represented 8.5 to 51.6% of reproducibility. It was noticed Horwitz ratios greater than 2 for three materials tested. It was found that 42.9% of the assessments show variations of the estimates as a function of days in which analysis was performed. Differences were also observed between procedures to assess mineral matter according to the different laboratories. The mineral matter contents estimate by each laboratory in this study have low reproducibility, which is aggravated by the interaction effect of material and laboratory.

title: Religiosity and quality of life of chronic renal failure patients under hemodialysis treatment

description: The study aimed to evaluate the correlation between religious attitude and quality of life (QOL) of 100 chronic renal failure patients under hemodialysis treatment. Data collection applied the questionnaires Socio-Demographic Data Form WHOQOL-Abbreviated Scale and the Religious Attitude Scale. The analyses revealed that component 1 of Religious Attitude Scale showed a correlation with the psychological domain of the WHOQOL-short (r=0.21, p&lt;0.05); component 2 correlated with QOL level of independence (r=0.28 , p&lt;0.01); component 3 correlated with the level of independence (r=0.22, p&lt;0.05) and with the social relationships domain (r=0.22, p &lt;0.05); satisfaction with QOL correlated with religiosity 2 (r=0.22, p&lt;0.05) component. Thus, one may conclude that religiosity is a source of comfort and hope to patients, providing overall well-being.

title: Urban entrepreneurs and the prodution of residential space: the ‘Condomínios-Clube’ in the South of Natal (RN)

description: This paper addresses the reasons that led to the spread of ‘Condomínios-clubes’ in Natal, Rio Grande do Norte state, Brazil, as well as the strategies put forward by urban entrepreneurs to promote the transformation of residential space in the city. The main result of this process is the consolidation of urban segmentation, which is a crucial element in the relationship between capital accumulation and production of urban space. Spatial innovation and its dissemination (convention), promoted by urban entrepreneurs in order to maximize profits, generates, as a rule, a certain homogenization of residential space; in this case, through the promotion of ‘Condomínios-clubes’. Based on authors such as David Harvey and Pedro Abramo to analyze the theoretical background, it is possible to understand the relationship between urban spatial form and capitalist development. In addition to a literature review, the methodology of this study also included open interviews with real estate managers in order to consider the relation between the built environment (housing stock) and the hegemonic discourse that seems to guide the residential market in the city. The results clearly show that this discourse tends towards a common objective; there is a convergence in the thinking and practice of real estate agents regarding the location and characteristics of each sort of real estate development. This has caused a sociospatial homogenization of certain neighborhoods at the expense of the rest of the city.

title: MOBILITY OF IMAZAQUIN HERBICIDE IN DIFFERENT SOILS TYPES

description: ABSTRACT: Imazaquin is an herbicide widely used in Brazil to control weeds associated with the soybean crop. This work aimed to study the mobility and leaching of imazaquin in soils with different characteristics. In both experiments, a completely randomized block design was used; with tree replicates. We study the mobility of imazaquin in Red Eutrophic Latosol, clayey; Alfisol Haplic Eutrophic, medium texture; Alfissol Eutrophic, medium texture; and Orthic Psament, sandy texture. To obtain the mobility rate (Mr), a solution of 14C-imazaquin with the activity of 304,75 Bq/mL was applied to plates containing different soils. All Mr values range between 0.803 and 1, indicating that imazaquin has a relevant mobility in our soils. In the leaching study, the soils were classified as Rhodic and differed chemically. The herbicide imazaquin (14C + imazaquin technical product) was applied to the highest recommended dose ( 161 g a.i. ha-1), directly on the soil surface of each column. After that, was done a rainfall simulation of 200 mm. Nearly 100% of the herbicide was in the 0-10 cm layer, however, the soil with higher pH, the herbicide was distributed to 15-20 cm depth. The herbicide imazaquin has greater mobility in soils with low organic matter and clay and soils with high Ph.
