Brazilian agribusiness is of significant magnitude, but dependent on external inputs, with emphasis on potassium, 96% imported. In Brazil there are several types of rocks that can be used for this purpose, but little explored. The objective was to evaluate the response of soybean sources of potassium (nepheline-syenite rock powder and KCl) and K2O doses (0, 25, 50, 100, 200 and 400 kg.ha-1) regarding biometric, physiological and productive aspects. The study was carried out in the 2021/2022 harvest at Fazenda Bonança, Montes Claros de Goiás-GO, in randomized blocks, with four replications. At the R1 stage, chlorophyll content in the leaves, stem diameter, plant height, and shoot dry mass were determined. At harvest, plant stand, grain moisture, weight of a thousand seeds and productivity were determined. Regardless of the potassium source used, soybeans responded to up to 100 kg.ha-1 of K2O. Lower grain moisture content at harvest was obtained with the application of nepheline-syenite rock powder. Its use was promising as a source of potassium for soybean, since it provided productivity similar to that obtained with the application of KCl, and could become an important alternative source of potassium for the region.

ABSTRACT Although acerola (Malpighia emarginata D.C.) has been suggested to be a climacteric fruit, little is known about its sensitivity to exogenous ethylene. The objective of the study was to evaluate the quality changes of acerola fruit at two harvest maturity stages in response to external ethylene application. ‘Flor Branca’ and ‘Junko’ acerolas were harvested at the maturity stages 1 (green fruit with density>1 g cm-3) and 2(green fruit with density

ABSTRACT The objective was to evaluate the quality of sunflower seeds classified according to their thickness and passed through the seeder-fertilizer dosing system under variation of the travel speed. A lot of M734 was classified by thickness passing the seeds through a set of oblong-hole sieves and two thicknesses were selected. A portion of the seeds with only the commercial classification was also reserved, named as non-classified. The biometric evaluation was done and the sowing was carried out at 5.0, 6.5, 8.0, 9.5 and 11.0 km h-1. The quality of the seeds was evaluated through: germination and first germination count, average time and percentage of emergence in sand, accelerated aging and tetrazolium test. The classification by thickness reduce the coefficient of variation of the length, width, thickness, and mass but seeds classification does not affect seed vigor and viability after sowing under speed variation. In the higher studied speed, the passage of seeds through the dosing mechanism reduces germination. The vigor is affected at 6.5 km h-1 speed by the accelerated aging test. According to the emergence in sand and tetrazolium test, speed variation does not affect the vigor and viability of sunflower seeds.

Resumo Objectives: to determine the prevalence of pathological findings according to the type of chorionicity in pregnancies in two institutions in Bogotá, Colombia. Methods: descriptive, retrospective, cohort study. Biometric variables were calculated, and pathological findings were evaluated according to the type of chorionicity in multiple pregnancies. Statistical characterization was performed with absolute frequencies, calculation of relative frequencies in qualitative variables, standard deviation measures, median and interquartile range. In addition, a descriptive analysis of the information was carried out. Results: 528 studies were carried out in 141 pregnant women, 98.5% (n = 139) twins and 1.4% (n = 2) triplets. A prevalence of 35.4% of fetal complications was calculated. The most frequent was fetal growth restriction (p=0.37). According to each type of chorionicity, fetal growth restriction was presented in 50% (1/2) of the trichorionics, 16.6% (7/42) of the monochorionics, and 11.3% (11/97) of the dichorionics. Conclusion: fetal growth restriction was the most common finding, both in trichorionics, monochorionics and dichorionics pregnancies.

Camucamuzeiro (Myrciaria dubia), a plant of the Myrtaceae family, is a fruit tree native to the Amazon region, occurring spontaneously in floodplains and on the banks of rivers and lakes. The objective of this work was to quantify the pulp yield and evaluate the morphometric characters of fruits and seeds in camucamuzeiro accessions established as progeny in the Germplasm Collection of Embrapa Amazônia Oriental in Belém, Pará. The physical characterization of the fruits was carried out based on a sample of 1600 fruits harvested from 32 progenies. The fruits were individually characterized according to the following aspects: weight, length, diameter, peel thickness and number of seeds per fruit. Seeds of 10 fruits per treatment were evaluated for weight, length, width and thickness. A completely randomized experimental design was used, with 32 progenies, and then the data. The results showed that the camucamuzeiro fruits have an average weight of 8.15g. The progenies CPATU-83 and CPATU-61 were the ones that stood out in terms of weight, with fruits presenting an average weight of over 11 grams. The average fruit length and diameter were 2.22 cm and 2.39 cm, respectively. The number of seeds averaged 1.92 seeds per fruit. Regarding °Brix, amplitudes of 10.70° and 6.93° occurred in the progenies CPATU-27 and CPATU-28. The pulp percentage of the progenies had an average of 68.70%, being CPATU-54, 62, 23, 24 and 17 statistically higher than the others. The percentage of seeds per fruit showed significant differences with the highest percentage of seeds in CPATU-27, 31 and 30, and the lowest value in fruits of the CPATU-23 plant. The germplasm collection of Embrapa Amazônia Oriental allows the identification of wide genetic variability among progenies of M. dubia. The camucamuzeiro progenies CPATU-17, 23, 24, 54 and 62 showed higher pulp yield. [ABSTRACT FROM AUTHOR]

The objective of this work was to carry out the morphobiometric characterization of fruits, seeds and seedlings of Khaya grandifoliola. The fruits were characterized by evaluating length, diameter and thickness of the pericarp, and the seeds by length, width, thickness, weight of 1,000 seeds and moisture content. Germination and seedling morphology were also analyzed. The data were submitted to descriptive statistical analysis and the seeds grouped into classes, through a frequency distribution, according to their length. The fruits of K. grandifoliola are capsule-type with longitudinal dehiscence, polyspermic, with approximately 48 seeds of intermediate predominance and flattened shape, with a slight extension in the tegument and slightly winged. The seeds vary in length from 19.84 to 38.31 mm, width from 18.10 to 20.77 mm and thickness from 2.25 to 2.82 mm, weight of 1,000 seeds was 274.12 g and moisture content was 6.8%. Primary root protrusion is visible from the fifth day after sowing, and germination is of the cryptocotyledon hypogeal type, with seedling formation at 14 days, with reddish-green primary leaves. The results obtained are important to support methodologies definition and future additions to the RAS on the K. grandifoliola species. [ABSTRACT FROM AUTHOR]

Prunus campanulata is a species largely adopted for landscape composition in Brazil with limited seedling production by seed dormancy, lacking studies about in vitro propagation. This study aims to evaluate different P. campanulata seed pretreatments on germination, and the effect of GA3 on dormancy break and seedlings biometry. Seeds were processed in three treatments: complete seeds, seeds without endocarp, and isolated zygotic embryos incubated in a WPM medium containing different GA3 concentrations (0.0, 2.0, and 4.0 mg L-1). After 30 days of in vitro incubation were evaluated the germination percentage, mean germination time, percentage of normal seedlings, percentage of seedlings with leaves, and survival percentage were. Seedlings greater than 3.0 cm were selected for ex vitro adaptation, evaluating after 32 days the biometric variables: total length, aerial part length, root length, and the number of leaves. Complete seeds do not germinate, suggesting dormancy associated with the endocarp, whereas seeds without endocarp and isolated zygotic embryos showed the same germination rate, with no effect on GA3. The GA3 promoted greater seedling growth at concentrations between 1.89 mg L-1 for the total length of the isolated zygotic embryo and 2.24 mg L-1 for the length of the aerial part of seeds without endocarp. In conclusion, seed processing, i.e., removing the endocarp or isolating the zygotic embryo can overcome dormancy, improving germination and seedling production of P. campanulata in vitro.

ABSTRACT Ocimum basilicum L. (basil) is an annual herb belonging to the Lamiaceae family that has economic importance for many regions around the world. Thus, ecophysiological studies are needed to assess this species growth and dispersal. This work aimed to obtain equations from regression models that meaningfully estimate the leaf area of basil cultivars using linear dimensions of leaves. For this purpose, 300 leaves from 'Italiano Roxo' and 500 leaves from 'Folha Fina' cultivar were collected from plants cultivated in a greenhouse. Then, the length, width, and leaf area of each leaf were measured, and product of length by width were calculated. The equations were adjusted using the simple linear, linear without intercept, quadratic, cubic, power, and exponential regression models. Criteria for selecting the best equations were highest determination coefficient and Willmott's agreement index, lowest Akaike information criterion and root mean square error, and BIAS index closest to zero. All the equations fitted using the product of length by width (L.W) can estimate the leaf area of basil cultivars. Thus, basil leaf area can be estimated through a non-destructive method using linear dimensions of leaves. However, the equation ŷ = 0.8175*LW0.9307 is the most suitable for 'Italiano Roxo' and ŷ = 0.6335*LW for 'Folha Fina'.

The objective of this study was to evaluate the productive performance and intestinal biometry of Japanese quails fed levels of corn distillery dry grain (DDG) in the rearing phase. A total of 660 Japanese quails (Coturnix japonica) were distributed in a completely randomized design with five treatments and six replications, with 22 quails per experimental unit during 20 days of experimentation. The treatments used were diet with 0% (control), 5, 10, 15 and 20% of corn DDG inclusion. The variables evaluated were feed intake, weight gain, feed conversion and intestinal biometry. Data were analyzed using the linear and quadratic regression model at 5% probability and Dunnett's test at 5% probability. The use of corn DDG showed a difference (P<0.05) for feed intake, and the inclusion level of 9.51% of DDG maximized this parameter. There were no differences (P>0.05) for weight gain and feed conversion. For intestinal biometry there was difference (P<0.05) only for jejunum and ileum length. In conclusion, it is recommended to include corn DDG in diets of Japanese quails in the rearing phase up to 10.1% without causing damage to performance parameters and intestinal biometry.

The accuracy of the intraocular lens calculation is not perfect, and postoperative refractive errors are common, especially in patients who have undergone previous refractive surgery or in presence of asymmetric corneas. Corneal power after refractive surgery can be more accurately measured using the total optical power map in the 4-mm central zone, by means of Orbscan II or equivalent keratometric reading map available on pentacam, with central measurements of 1.0, 2.0, 3.0 and 4.5 mm. The purpose of this case series is to demonstrate four approaches performed in special corneal conditions, using pentacam equivalent keratometric reading to measure corneal power and biometrics, and comparing with possible results obtained with other strategies. The four eyes were submitted to previous refractive procedures, and the intraocular lens chosen from the use of the corneal power calculated by equivalent keratometric reading showed excellent postoperative results.

ABSTRACT Bell pepper (Capsicum annuum) is one of the most consumed vegetables around the world. Balanced fertilization is essential for growing this vegetable. The objective of this study was to evaluate the yield and morphological attributes of bell pepper under doses and times of application of biological fertilizers. Two experiments were carried out with applications of biological fertilizers prepared from manure and enriched organic compounds with cattle manure and sheep manure. The experimental design was a randomized complete block design, in a 4 x 3 + 1 factorial scheme, with three replications, referring to doses of biological fertilizers (100, 200, 300 and 400 L ha-1), times of application (0, 30 and 60 days after transplanting - DAT) and control. The evaluated variables were: total fruit weight (TFW), number of commercial fruits (NCF), number of non-commercial fruits (NNCF), fruit weight (FW), fruit diameter (FD), fruit length (FL), resistance of fruit peel (RFP), number of flower buds (NFB) and productivity (P). Biological fertilizers caused positive effects on TFW, NCF, FW and P of bell pepper. The application of cattle manure at 60 DAT and sheep manure at 30 DAT promoted a larger fruit diameter. The FW, FL and RFP were influenced by the doses and times of application of biological fertilizers. The application of biofertilizers is efficient in the production of bell pepper.

ABSTRACT: The aim of the present study was to describe the dynamics of glucose and insulin curves in pregnant mares, and to evaluate the curves according to body condition score, identifying the presence of insulin resistance and correlating these values with the weight, height and clinical changes of the neonates. For this, pregnant mares were evaluated and then grouped according to body condition score during the gestation length until lactation. GrM corresponds to mares with moderate body score (BCS 5-6); GrOv were mares with overweight body score (BCS 7) and GrOb were obese mares (BCS 8-9). A two-step oral sugar test (OST) was used to determine the data. Cortisol analysis was performed with 300-320 days of gestation, at foaling and after parturition. For evaluation of the neonate, a general clinical examination and, weight and height measurements were performed. The results showed hyperglycemia in response to OST with normal insulin values at foaling with a subsequent fall in both values at lactation disregarding group division. Baseline glucose was decreased in GrM compared to GrOv and GrOb with 70-100 days of gestation and with 130-160 days of gestation. With 270-300 days of gestation and post-partum GrOb had increased baseline glucose than GrM. After OST, glucose at foaling day in GrOb presented increased values than GrM. Baseline insulin values did not differ between groups. Post OST insulin levels were higher in GrOb than GrM and GrOv at parturition. No difference in cortisol between moments was identified. GrOb and GrOv maintained increased concentrations after foaling while GrM had a decrease. No correlation was found between maternal glucose and insulin values with foal weight and height, however, a lower ratio between neonatal weight and mare’s weight in GrOb and GrOv was identified in relation to the GrM. At foaling, mares presented glucose dysregulation, with obese and overweight mares presenting a greater response to OST.

ABSTRACT: Heterosis plays an important role on yield and profitability of beef production systems. This study evaluates the morphometrics of purebred Nellore (N) and Charolais (C) animals and of the second (G2) and third (G3) generations of their alternating crosses, regarding the effects of genetic group and heterosis from birth to 365 days of age. The experiment comprised 159 calves (C = 29, N = 22, G2 - 3/4C 1/4N = 21, 3/4N 1/4C = 9, G3-5/8C 3/8N = 44 and 5/8N 3/8C = 34). The foreshank girth (FG), thoracic girth (TG), body length (BL), and hip height (HH) were measured after birth, and at 63, 210, and 365 days of age, and the total increases were calculated. The Charolais animals had greater FG, TG, and BL values than Nellore, while the latter had greater HH. For the offspring generations, the predominance of Charolais genes in the genotypes resulted in greater measurements for FG and TG in G2, whereas the predominance of Nellore genes resulted in higher HH values in both generations. The crossbred animals had greater values for all measurements than the purebreds, with more significant differences in FG, TG, and BL compared to Nellore purebreds and in HH compared to Charolais. Charolais animals show higher values for muscularity; while, Nellore animals are taller. Crossbred animals show greater development compared to purebreds, indicating a significant effect of heterosis.

ABSTRACT Objective To compare the performance of Sanders-Retzlaff-Kraft/Theoretical, Hoffer Q, Barrett Universal II, Kane, and Hill-radial basis function formulas to calculate intraocular lens power in eyes with normal axial length, in terms of predicting target refraction by using partial coherence interferometry technology. Methods Phacoemulsification and intraocular lens implantation were performed in 135 eyes of 135 patients with an axial length between 22 and 24.5 mm. Axial length, keratometry, and anterior chamber depth were measured by intraocular lens Master 500. Sanders-Retzlaff-Kraft/Theoretical, Hoffer Q, Barrett Universal II, Kane, and Hill-radial basis function formulas were used for intraocular lens power calculations. The difference between the expected postoperative refraction and the mean absolute prediction error was calculated for each eye. Statistical significance was evaluated at the level of p0.05). Conclusion The study showed the third-generation (Sanders-Retzlaff-Kraft/Theoretical and Hoffer Q), fourth-generation (Barrett Universal II) and new-generation (Kane and Hill-radial basis function) intraocular lens power calculation formulas had similar performances regarding calculation of intraocular lens power to predict target refraction after phacoemulsification in eyes with normal axial length.

Introduction: Intraocular lens (IOL) power calculation, based on ocular biometry, is a determinant for the success of cataract surgery. Objectives: To characterize the ocular biometric parameters of Colombian patients over 40 years of age who are candidates for cataract surgery and to determine the prevalence of the 9 clinical conditions proposed by Holladay according to the interaction between axial length (AL) and anterior chamber depth (ACD). Materials and methods: Analytical cross-sectional study. The ocular biometry results of 781 patients (831 eyes) who were going to be taken to cataract surgery between January 2014 and January 2015 in Medellín, Colombia, were reviewed. After applying exclusion criteria, 716 eyes were included for analysis. Data on age, sex, AL, keratometry (flat keratometry (K1) and steep keratometry (K2)), ACD and white-to-white distance were collected. Results are presented using descriptive statistics. Results: Most eyes were from women (62.3%). The mean values of AL, K1 and ACD were 23.37±1.51mm, 43.52±2.06 and 3.03mm±0.41, respectively. Mean AL in men was 23.62±1.37mm, and in women, 23.21±1.67mm. The highest mean AL was observed in patients

The guabijuzeiro (Myrcianthes pungens) stands out for its coverage throughout the national territory and for the production and sweet taste of the fruits, but few studies have been conducted with this species so far. The objective of the present work was to carry out the biometric characterization of the fruits and the sensory analysis of the juice produced from three guabiju accessions. The methodology used consisted of collecting the fruits for analysis of fruit mass, pulp mass, pulp yield and Brix grade and for the production of guabiju juice. An acceptance test was carried out with 35 untrained evaluators. As a result, it was observed that the average fruit mass was 3.57 g, the pulp mass was 1.81 g, the pulp yield was 49.67 % and the average Brix grade was 14.27 %. Regarding juice production, access 1 produced 300 mL, access 2 200 mL and access 3 400 mL. Regarding sensory analysis, access 1 obtained the best acceptance score by 11.42 % of the evaluators, access 2 by 80 % of the evaluators and access 3 by 8.57 % of the evaluators, which shows the potential of use of these fruits for the development of juices with exotic fruits. It can be concluded that there is variation between accessions in fruit biometry, juice production and degree of acceptance by guabiju juice tasters. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the effect of immunocastration on the scrotal circumference, as well as in the macroscopic and microscopic testicular features in Nellore bulls bred under a semi-confining system for 91 days. Sixty animals were divided into two groups: 30 intact animals (non-vaccinated) and 30 immunocastrated animals. The immunocastrated animals were treated with two anti-GnRH vaccine doses (BoprivaTM - Zoetis Australia Pty Ltd). The scrotal circumference (SC) was measured on days 0 and 56. Testicular parameters: biometry traits (length, width, and height – cm; volume – cm3 ) and weight (g) was measured on day 91. Three testicles from each group were histologically processed to find the seminiferous tubule diameter and epithelium thickness (µm). Data were analyzed in the Minitab® 19 statistical software. The macroscopic features (SC, and testes weight, volume, length, width, and height) and the microscopic features (seminiferous tubule diameter and epithelium thickness) were compared between the two groups through Student’s t-test and Mann-Whitney test. All the values were lower (p

Abstract: The objective of this work was to assess the effect of genetic group and heterosis on the relationship between body weight and morphometric measurements, in purebred and crossbred animals from the second (G2) and third (G3) generations of Nellore and Charolais calves. Body weight (BW), average daily weight gain (ADG), foreleg circumference (FC), thoracic girth (TG), body length (BL), and croup height (CH) were measured at birth and at 63, 210, and 365 days of age in animals from G2 and G3. Charolais animals were superior to Nellore ones for gains BW, ADG, BL, and TG, as well as for the ratio between BW gain and CH gain; Nellore animals were superior for CH gains. Crossbred animals of both generations were superior to the purebred animals for gains of BW, BL, and CH. In G2, the predominance of Charolais genes resulted in greater gains of BW, ADG, FC, and TG. The G3 animals were superior to the purebred animals for ADG, FC, and TG. No differences were found for the ratio between gains of weight and morphometric measurements. Heterosis and complementarity are apparent for weight and body measurements of crossbred calves from rotational crossings.

ABSTRACT The specie Anadenanthera macrocarpa (Benth.) Brenan, angico-vermelho, is little studied regarding the morphological characters of its seeds, seedlings and tirodendo. Therefore, the aims of this study were to describe and illustrate the morphology of seed germination, seedling and tirodendro of angico-vermelho. Seeds of five matrices were harvested and submitted to germination test at 28 °C on paper roll and vermiculite substrates. The seeds are euryspermics with horseshoe-shaped pleurograma and seedlings epigeal-phanerocotylar. The seedling eophylls are compound, bi-pinnate, opposite, oblong-shape laminar and based asymmetric. Petiole has reddish oval gland at the beginning, and two to three rounded glands between the last pinnae. Eophylls and metaphylls have similar morphological characteristics, except for the pinnae number. The tirodendro presents metaphylls compounds bi-pinnate opposite, with gradual hypertrophy of the taproot 27th day after sowing, the xylopodium, that becames larger until 180 days.

ABSTRACT The objective of this work was to use biometric measurements to predict carcass characteristics of lambs of the Morada Nova breed. We used 48 lambs with mean initial body weight (BW) of 15.0±0.04 kg and slaughter body weight (SBW) of 26.37±2.43 kg. The animals were weighed weekly and underwent a period of adaptation of 15 days before slaughter. The biometric measurements were obtained the day before slaughter, comprising body length, withers height, rump height, thigh length, breast width, rump width, thigh perimeter, rump perimeter, thorax perimeter, leg length, and body condition score. Additional measurements included slaughter BW and empty BW (EBW). The data recorded at slaughter comprised the weights of the viscera, carcass, and internal fat and offal. The in vivo measurements of body length were present in most of the equations for predicting the SBW, EBW, hot carcass weight (HCW), and cold carcass weight (CCW). The SBW and EBW presented a variation of approximately 9%. The variables that evaluated the carcass, HCW, and CCW demonstrated less data variation than SBW and EBW, which was probably because these measurements were obtained following evisceration and skinning, thus removing factors of more significant variation in vivo . The prediction models found in the present study varied with an R² of 0.49-0.93, indicating high levels of variation. In sum, biometric measurements can be used to predict the carcass characteristics of Morada Nova lambs with different body conditions.

Path analysis is a tool used in soybean breeding programs to better understand how characters between characters, decomposing as correlations in direct and indirect effects. Given this, it is possible to evaluate by path analysis the influence of agronomic characters on research in commercial soybean cultivars of different cycles. The experiment was conducted in Serra do Salitre City, Minas Gerais State. Nine cultivars are divided into early (SYN1163IPRO, CD2687RR and P95R21RR), medium (SYN1080RR, CD2728IPRO and P97Y07RR) and late (SYN13870IPRO, CD237RR, and P98Y30RR) cycles. Were evaluated the grain productivity and agronomic characters: plant height, first lane insertion height, number of nodes produced, number of lanes per plant, and number of grains per plant. The multicollinearity analysis was initially performed, followed by the path analysis, adopting the crest regression procedure. To the SYN1163IPRO, CD2687RR, P95R21RR, SYN1080RR, and P97Y70RR cultivars the number of pods per plant and the number of grains per plant, or the ones that most influence soybean use. For cultivar CD237RR and P98Y30RR plant height and first pot height were the major effects on soybean percentage, respectively. [ABSTRACT FROM AUTHOR]

In the next issues of Clinical and Biomedical Research, the Biostatistics section will introduce a new series of articles addressing a very important subject for research planning: the minimum sample size to achieve the aim of a study. This series will show how to calculate sample size using PSS Health (Power and Sample Size for Health Researchers). This tool was built using R language through the Shiny package. It can be used for different types of study and is designed for health researchers by using terms and concepts commonly used in this area. PSS Health also suggests a text with information considered in the calculation to minimize problems of interpretation by the researchers. In this first article, a general overview of PSS Health will be presented. This tool, which was developed by the Research and Graduate Group Biostatistics Unit of the Hospital de Clínicas de Porto Alegre, is useful not only to calculate sample size but also to determine power of a hypothesis test.

Abstract Estimating leaf area is essential to evaluate vegetal growth. Our study sought to obtain statistical models to allow the leaf area estimation of Palicourea racemosa, considering its length (L) and width (W). For such purpose, we collected 200 leaves of this species in the State Park Mata do Pau-Ferro, in the municipality of Areia, Paraíba, Northeast of Brazil. The regression models used were: linear, linear without intercept, power and exponential. The choice of the best equation was based on the values of the coefficient of determination (R2), root mean square error (RMSE), Akaike information criterion (AIC), Willmott concordance index (d) and BIAS ratio. All linear and power models may be used to measure the P. racemosa leaf area; however, the power model LA = 0 . 609 * ( L . W ) 0 . 995 is the most recommended to estimate this species’ leaf area.

Objective: Observe the agreement between IOL Master 500 and Pentacam AXL and describe the averages. Methods: We analyzed 35 medical records, totaling 61 eyes. All patients underwent biometric evaluation on both devices from August 2018 to August 2019. The data collected were: age, gender, anterior chamber depth, axial length, K1, K2, biometrics and IOL target. Results: The averages of the variables analyzed between the optical biometric devices in question had a statistically significant difference (p <0.05). Linear regression showed no influence of any anterior chamber variables on the difference in biometrics and target values between the devices. Conclusion: There was no statistical agreement between the devices for the analyzed variables. Therefore, the interchange of Pentacam AXL with IOL Master 500 should be avoided.

This work aimed to characterize seed biometry of Solanum paniculatum L. and to evaluate seed germination after overcoming dormancy with sulfuric acid (H2SO4). A completely randomized experimental design was used with four repetitions of 25 seeds, each. Treatments to overcome dormancy were: immersion in H2SO4 during 5, 10, 15 and 20 minutes and intact seed as control treatment. Seeds were sown on gemitest paper and placed in a Biochemical Oxygen Demand (BOD) germination chamber at 30 °C with a photoperiod of 12 hours. Percentage of germination (G%), germination speed index (GSI), mean germination time (MGT) and relative frequency of germination (RF) were evaluated. A 200-seed sample was selected for biometry characterization. Statistical analysis was performed using the software InfoStat. Jurubeba seed presented average values of length, width, thickness and fresh mass of 3.9; 3.3; 1.3 cm; and 10 mg, respectively. Biometrics data showed high variability for seed fresh mass. Analysis of variance indicated that all variables were significantly influenced by seed exposure time in H2SO4. Optimal germination performance of jurubeba seeds pretreated with H2SO4 is obtained in a time interval of 11 to 12 min. [ABSTRACT FROM AUTHOR]

Determining equations to estimate with precision the volume of commercial trees is relevant for decision taking on the use of the forest and on the establishment of public policies for the monitoring and control of natural resources, their valorization and investments. Current paper develops volume equations for the Dense Ombrophilous Forest in Ipixuna, northeastern region of the state of Pará, Brazil. The real volume of 296 sample trees was determined according to the Smalian method. Forty-six trees were selected for a database for the validation of the equations. Twelve mathematic models were tested, of which six had simple entrance and six had a double entrance. Simple entrance models proved to have the best adjustment quality for the Hohenald & Krenn model, with equation v = 5.29918-0.1374d+0.00010d² (R²aj. = 0.84, Sy.x% = 19.81; DMP% = -3.63). In the case of double entrance, the best was Schumacher & Hall model, with equation Logv = -3.7657+1.9242.logd+0.7540.logh, (R²aj. = 0.96, Sy.xr% = 10.46, DMP% = -0.34). After validation of selected equations, the Schumacher & Hall was recommended to estimate the volume of commercial trees in the municipality of Ipixuna due to high precision adjustment.

Abstract Purpose To determine cervical biometry in pregnant women between 18 and 24 weeks of gestation and the ideal mode of measurement of cervical length in cases of curved and straight cervical morphology. Methods The uterine cervices of 752 low-risk pregnant women were assessed using transvaginal ultrasound in a prospective cross-sectional study. In women with straight uterine cervices, cervical biometry was performed in a continuous manner. In women with curved uterine cervices, the biometry was performed using both the continuous and segmented techniques (in segments joining the cervical os). Polynomial regression models were created to assess the correlation between the cervical length and gestational age. The paired Student t-test was used to comparemeasuring techniques. Results The cervical biometry results did not vary significantly with the gestational age and were best represented by linear regression (R2 = 0.0075 with the continuous technique, and R2 = 0.0017 with the segmented technique). Up to the 21st week of gestation, there was a predominance of curved uterine cervix morphology (58.9%), whereas the straight morphology predominated after this gestational age (54.2%). There was a significant difference between the continuous and the segmented measuring methods in all the assessed gestational ages (p < 0.001). Conclusion Cervical biometry in pregnant women between 18 and 24 weeks was represented by a linear regression, independently of the measuring mode. The ideal measuring technique was the transvaginal ultrasound performed at a gestational age 21 weeks.

Abstract The estimation of pineapple total leaf area by simple, fast and non-destructive methods allow inferences related to carbon fixation estimative, biotic and abiotic damages and correlating positively with yield. The objective was to estimate D leaf area and total leaf area and of ‘Pérola’ pineapple plants from biometric measurements. For this purpose, 125 slips were selected and standardized by weight for planting in pots. Nine months after planting in a greenhouse, the plants were harvested to evaluate the total leaf area of the plant, D leaf area and D leaf length and width using a portable leaf area meter. Pearson correlation analysis was made and it was observed significative positive and strong correlation among the studied variables. Then, regression models were adjusted. It was observed that the D leaf area of ‘Pérola’ pineapple can be estimated from the length and width of this same leaf and the total leaf area can be estimated from the D leaf area.

The objective of the present study was to test multivariate tools to evaluate the growth of Berganês and crossbreed in the Northeastern Semiarid region. Biometric measurements were performed at the beginning and at the end of the experiment in uncastrated male lambs belonging to the Berganês (BG), Berganês x Santa Inês (BSI), Dorper x Berganês (DB) genotypes and the Dorper x Santa Inês (DSI), of eight lambs per genotype. The design was completely randomized. Data were subjected to Person correlation analysis. It performed factor analysis based on principal components - (FA), in order to summarize the original set of variables in a few factors and to indicate the variables that most contribute to the evaluation of animal growth. A significant correlation (p < 0.01) was observed for most variables measured at the end of the experiment. The most important characteristics to evaluate the biometric growth of Berganês and crossbreed lambs are associated with the breed pattern and body development of the animals, according to factor analysis. The lambs were classified in their respective genotypes at the end of the experiment according to the discriminant analysis. The multivariate techniques used in this study were handy to understand and differentiate the Berganês genetic group and its crossbreed based on biometric characteristics. [ABSTRACT FROM AUTHOR]

The objectives of the study were to characterize the ovarian dimensions and evaluate two techniques of recovering COC's (Cumulus-oocyte complexes) from the ovaries of gilts with an average age of five months and average body weight of 80 kg. Ovaries from slaughterhouse were used (n=127), which were weighed using a digital balance and measured (length, width and height) with a caliper. Of the 127 ovaries, 38 were submitted to follicular aspiration and 20 were sectioned using a scalpel. The COC's of those 58 ovaries were classified with grades 1, 2, 3 and 4 using a stereomicroscope. The means of COC's recovered according to those techniques were compared by t test (P<0.05). The variables were correlated using the Pearson Correlation test. The average results observed were: ovarian weight 4.26 g; length 2.57 cm; width 1.99 cm and height 1.39 cm. A total of 5,871 COC's were recovered from the 58 ovaries. The percentages of each grade were as follows: 0.87%; 2.23%; 14.50% and 82.40% (grades 1, 2, 3 and 4 respectively). Of the total number of COC's collected, grade 4 was the most prevalent and significant to this experiment. Body weight and ovarian width have more influence on the quantity and quality of COC's. It is concluded that the ovarian section method provides greater recovery of COC's. When the technique of recovering COC's is used in prepubertal swine females, the recovery of grade 4 COC's prevails. [ABSTRACT FROM AUTHOR]

Current analysis was undertaken in the western region of the state of Paraná, Brazil, an agrostockbreeding reference center in fish production, characterized by 17 fish abattoirs and industries. The study informs the producer on fattening of fish lots and analysis of ponds' water quality to verify faults in management that contribute towards the difference in fish finishing size. Six ponds in four small farms in the municipality of Toledo PR Brazil were monitored during five months (October 2018 - February 2019). Samples with 50 specimens per pond were used for biometry, weighed and measured individually. Weight difference was calculated by sample standard deviation of each lot. Multiparameter probe measured temperature, pH, electric conductivity, dissolved total solids, dissolved oxygen and turbidity. Results showed strong relationship between turbidity, total dissolved solids and electric conductivity and difference in tilapia size. Over population in the ponds was also detected. Standard deviation of weight increased according to fish growth. Results show that water quality directly affects the development of fish and lack of proper management contributes towards an increase in differences in tilapia weight and size.

The aims in this study was test the genetic discernment among five goats populations of the Republic of Cape Verde (n=533) by biometric data and statistical analysis. It were analysed 16 characteristics in adult goats, through descriptive statistics, analysis of variance, test for multicollinearity, Mahalanobis distance (D²) and UPGMA algorithm (Unweighted Pair Group Method Arithmetic Mean). After the test of multicollinearity was identified and discarded the variable thoracic depth. The D² were calculated using 15 biometric measurements. The maximum value of D² was between the populations of the islands of Fire and São Nicolau (22.73), and D² was lower between Santo Antão and São Vicente (3.71). The dendrogram based on biometric data in five populations put the goats on the Fire Island in other branch. Clustered in one the branch the goats from the islands of Santo Antão and São Vicente. This result is consistent with the geographic distance among the islands of Cape Verde and the recent history of exchange of animals among them. [ABSTRACT FROM AUTHOR]

The objective of this study was to perform the morphometric characterization and classification of common bean seeds, Carioca, Gordo, Ovo-de-rola and Preto varieties, for agroecological cultivation. The research was carried out during the month of October, 2018, in the Phytopathology Laboratory of the Center of Agrarian and Environmental Sciences of the State University of Paraíba, located in the municipality of Lagoa Seca, Paraíba. Creole seeds of common bean (Phaseolus vulgaris L.) of the Carioca, Gordo, Ovo-de-rola and Preto varieties were used by producers in the region of Montadas, Paraíba, during the 2018 harvest. For each variety, four subsamples of 50 seeds were taken, totaling 200 units. The results showed that, among the bean varieties, the Feijão Gordo variety showed the best results, being 13,6 mm long, 7,2 mm wide, 6,3 mm thick and 0,40 g mass. [ABSTRACT FROM AUTHOR]

Tamarindus indica L. is a tree species very appreciated for ornamentation, being considered a multifunctional tree, since it can be used pulp, seeds, flowers, leaves, wood, bark, whether for nutritional or medicinal use. In addition, this species presents in its chemical composition amino acids, fatty acids, minerals, being outstanding for presenting excellent nutritional qualities. Thus, the present work aimed to characterize the biometry of fruits and seeds of Tamarindus indica L. For this, the biometry was performed using a random sample of 100 fruits and 100 seeds. Mass, length, width and thickness of fruits and seeds and number of seeds per fruit were evaluated. The fruits of Tamarindus indica presented average values of length, width, thickness and mass of: 59.72; 22.80; 15, 29 mm and 7.78 g respectively, with an average of three seeds per fruit. In the biometric analysis of the seeds we observed averages of length, width, thickness, and mass of 14.7; 10.15, 3.85mm and 1.12g respectively. The fruits and seeds of Tamarindus indica showed variability in their biometric characteristics, for the trees evaluated in this study. The fruits presented greater variation in length, while in the seeds it was observed greater variability in thickness and width. [ABSTRACT FROM AUTHOR]

Currently, around the world there are several exchanges clubs, where groups of people exchange goods and services with mutual and in a friendly manner to keep its characteristics and exchanges. Also, there is the possibility of inserting a local currency without the purpose to make profit by third parties, to facilitate the value recovery system of products and services for the poorest communities. Therefore, this project creates a biometric access software with a simple usability and low cost of computing resources for deploying and managing a virtual social currency focused on local communities, in order to provide a social inclusion and regional development. The development of a biometric computer system by controlling access by face recognition validation which makes it faster and cheaper to deploy a local currency system given that there is no need to ballots printing or magnetic cards that can become more expensive and not always easy to obtain them. With software developed, the initial tests turned out with positive results because the access security system product requires affordable equipment to any seller and/or community that aims to create a social currency system.

Background: Coatis (Nasua nasua) have easy interaction with man, besides being sociable and curious animals. The proximity to urbanized areas encourages them to intake food from anthropogenic sources, and it can change their eating habits and make them prone to obesity. The body condition evaluates the animals' energetic status and measures variations in their body fat reserves. There are direct-invasive methods and indirect methods that rely on size and body mass to evaluate the body condition, like body condition score and body mass index. Thus, the aim of the present study was to assess different methods to determine the body condition of wild coatis (Nasua nasua) living in urban areas. Materials, Methods & Results: Sixteen wild coatis (Nasua nasua), nine females and seven males, were captured at Faculty of Veterinary Medicine and Animal Science (FMVZ) of São Paulo State University, Botucatu, in pitfalls. The animals were anesthetized with ketamine and midazolam and subjected to biometric evaluation after physical exams proved normal. The following variables were analyzed: body weight, body condition score (BCS) based on the five-point scale for dogs, thoracic and abdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus. Two body mass index (BMI) were calculated from these data, one was based on dogs (BMI1) and another one on cats (BMI2), as well as the body fat percentage (%BF). Results showed that 25% of the assessed coatis were overweight. Body weight, thoracic and abdominal circumference, height at the withers, spine length and distance from the patella to the calcaneus were significantly higher in males than in females and the other assessed parameters did not present differences between sexes. The correlation between fat percentage and body weight was significant, and that between fat percentage and BCS was not. There was closer correlation between BMI2 and body weight, and BCS, than between BMI1 and these two parameters. Discussion: Anthropogenic interactions could change the body condition of these animals and make them prone to obesity, since their body condition scores were altered. With regard to the nutritional body condition, although males were bigger than females, the measures did not show significant differences between them. Results of this parameter varied in different studies with coatis, some studies have shown that males have body mass 1/3 higher than that of females and others have not recorded any difference between sexes. Fat percentage estimated through the metrics used in cats is not a good method when it is applied alone in body condition evaluations. A study that has correlated body mass, body condition score, body fat estimates, body mass index and abdominal circumference recorded positive results between these two evaluation methods. Such finding corroborated with the present study, but it was differed from it in abdominal circumference, which did not correlate to the two body mass indices and to body fat percentage. Therefore, it is possible saying that there is biometric difference between male and female coatis. The body condition score adopted for dogs was efficient for coatis (Nasua nasua), as well as the body mass index used for dogs and cats - the one used for cats was even more efficient. The proximity wild coatis (Nasua nasua) have to humans could change the body condition of these animals and make them prone to obesity. [ABSTRACT FROM AUTHOR]

Human speech has been studied in different areas of knowledge, which range from biometry to phonetics and phonology. In research conducted in such areas, speech samples are necessary resources for obtaining results and validating hypotheses. For this, samples of different speakers and contents are stored in audio files and organized into databases. Such databases allow the continuity, practicality and reliability of studies, eliminating the difficult and time consuming step of data collection. Moreover, they allow consistent comparisons between different studies. However, free access databases in the Portuguese language or recorded in controlled environments are rarely found. The objective of this paper is to construct a free and public database of Brazilian Portuguese, named Corpus CEFALA-1. The database comprises 104 speakers guided by a specific protocol for the collection of audiovisual speech samples recorded in a studio. The paper presents the methodologies for processing, segmentation and organization of speech samples, statistical analysis, application to biometric verification and preliminary phonetic-phonological analyses.

This study aimed to verify the influence of the size of the diaspores and scarification treatments on the emergence rate and initial growth of Pterodon emarginatus Vog. (Fabaceae) after one year of storage. Diaspores of the species were collected, measured, weighed and separated into three size classes, with amplitude determined by the width of the fruit. Subsequently, they were submitted to thermal and mechanical scarification. A randomized experimental design was used, with 10 replicates of 10 units / each. We performed a survival analysis, besides analysis of variance and Tukey post-hoc test to verify significant differences in the percentage of diaspores emergence. We used generalized linear models to verify the variation in the initial growth of the seedlings. Our results indicated that treatments intercropped with the largest diaspore sizes positively influenced the percentage of emergence. Larger diaspores also resulted in larger diameter seedlings and stem length. Mechanical scarification led to a higher biomass allocation in the roots. We suggest that P. emarginatus diaspores should be submitted to pre-germination treatments to potentiate seedling emergence and development. We also recommend choosing the largest diaspores.
