Objective: to describe the effects of the new coronavirus pandemic carried out by the mobile emergency care service (SAMU) in Senador Canedo-Goiás in the period 2019-2020. Methods: This is a descriptive ecological study, using the SAMU service bulletins of the respective municipality as a source of information, referring to the period from January 2019 to December 2020. The absolute and relative frequencies of the selected variables were calculated and calculated the chi-square test with a significance level of 5% (p< 0.05). Results: In 2019, 1,078 occurrences were recorded, while in 2020, 1,705 were attended, showing an increase in the number of calls between years. Most attendances were male (2019-2020 - 59.4%) aged between 19 and 45 years (2019-2020 - 36.3%). The main place of occurrence was at home (2019-2020 - 45.9%), in the afternoon shift (2019-2020 - 34.1%) and the highest occurrences were carried out on weekends (2019-2020 - 32, 1%). The main type of occurrence was due to assistance in both years (2019-90.5%; 2020-79.6%), although removal/transport showed a significant demand in 2020 (2019-9.5%; 2020- 20.4% - p= <0.0001). The main reason for attendance was due to clinical causes (2019-19.5%; 2020-28.5% - p= 0.914), followed by external causes (2019-15.3%; 2020-26.6% - p=<0.0001). Conclusion: it was observed that the pandemic significantly influenced the increase in cases of occurrences in the year 2020, increasing the number of removals/ transportation, impacting the health service and it is expected that the unpublished data from the sample obtained can serve as a substrate for the planning and execution of measures aimed at improving health care.

Given that knowledge of hazardous substance pictograms is fundamental in the promotion of attitudes to minimize impacts on health and the environment, this study was carried out with the following aims: i) to assess the level of comprehension of hazardous substance pictograms, as defined by Professional Higher Technical Course students at a higher education institution; ii) to understand the way the training strategy that was followed with the students contributed to a conceptual change in the interpretation of hazardous substance pictograms, and; iii) to underline the importance of hazardous substance pictogram comprehension in minimizing the risk of environmental, workplace accidents and occupational disease. Comprehension of these pictograms by 669 students was assessed before and after training on the subject. Data analysis by a pictogram, as a function of the area of training, age and having, or not, the status of student worker or not, was performed through descriptive statistics tools and hypothesis testing. The average level of correct understanding of the pictograms after training (61.19%) was higher than observed before training (30.75%). Training on chemical hazards is essential for the improvement of understanding of the corresponding pictograms and should be valued and addressed in school curricula beginning with mandatory education and continuing through to the higher education level.

The objective of this study was to evaluate the antibacterial activity of different endodontic cements (MTA Fillapex, Sealapex, Sealer 26, and Endofill), both pure and mixed with 5% of amoxicillin or ciprofloxacin, against two strains of Enterococcus faecalis (ATCC 29212 and ATCC 4083). Bacterial susceptibility testing was conducted by radial diffusion methods and direct contact test after different periods. Data were subjected to ANOVA and Tukey test with a significance level of 5%. Sealapex was the only pure sealer to promote the inhibition of bacterial growth against both strains in different experimental periods. However, all cements present an increase in antibacterial activity by the addition of antibiotics (p<0.05). MTA Fillapex and Sealapex associated with amoxicillin promoted increased values for bacterial growth against ATCC 29212 and ATCC 4083 in comparison to other groups (p<0.001), including extended periods after setting time. The association of antibiotic agents increased the antibacterial effect of the evaluated sealers against the strains of E. faecalis. [ABSTRACT FROM AUTHOR]

The objective of this study was to demonstrate the influence of the type of training on the measurements of the palmar flexor tendons in vaquejada horses that run to the right of the ox in the microregion of the Alto Médio Gurgueia, South of Piauí, Brazil. Eight animals of the quarter-mile breed and their crossbreed, of different ages, weight and sex, were selected and asked about the time they were engaged in the activity of the vaquejada and the type of training they were submitted to as they practiced running on which side of the ox, in a vaquejada test in the municipality of Cristino Castro, South of Piauí, Brazil, where the participants came from different farms of the microregion of the Alto Médio Gurgueia, South of Piauí, Brazil. The ultrasonography of the IB, IIB and IIIB zones of the superficial digital (TFDS) and deep digital flexor tendons (TFDP) were performed in each animal, obtaining the measurements of the lateral diameters (DML) and palmar dorsum (DDP) through the transverse plane in each of the different zones. Data were submitted to statistical analysis (ANOVA), using the t test at the significance level of (p <0.05), observing that there was no significant difference between the measures evaluated. According to the results, horses for vaquejada athletes do not present significant difference in the lateral diameters and palmar dorsum of the flexor tendons between the right and left thoracic limb antimeres.

In this study, we adopted the strategy tripod to assess the extent to which elements related to industry, companies, and institutions affect the formulation of strategies and the perception of performance in companies in the same sector and the same geographic region. We developed the research in two phases, a qualitative phase, through interviews with CEOs of companies inserted in the information technology sector, and a quantitative phase, with the application of a survey to assess the extent to which these elements determine the results of the companies. These elements were analyzed using multivariate statistics and the hypotheses tested using linear regression. The tests revealed that among the eight hypotheses built, only three found support. The main result shows that the strategy tripod's dimensions do not work together in the formulation of strategies and the effects on performance. This study's managerial implications focus on the operational management of the investigated sample, making it challenging to idealize a long-term view and develop synergies for the formation of networks. Studies that approach the strategy tripod consider different institutional environments; in this sense, this study advances by measuring the strategy tripod in a homogeneous institutional context.

It was found association between Food Insecurity and the variables: educated mothers, monthly income of the families and the receiving of social benefit. Conclusion: a considerable number of children assessed who live in the countryside are in Food Insecurity situation; the associated factors relate to the social vulnerability of families. It is necessary to take actions that in fact will improve the access to food and living situation of these families. [ABSTRACT FROM AUTHOR]

Evaluated the production of melon seedlings placed on substrates based on shredded cassava branches and submitted to composting periods. The experiment was carried out in a protected environment and a completely randomized design in a 5 x 2 factorial scheme was adopted. The treatments corresponded to the combination of five composting periods of shredded cassava branches (0, 30, 60, 90 and 120 days) and two melon cultivars (Gaúcho Casca de Carvalho and Melão Amarelo). At seedling emergence, the emergence speed index and emergence percentage evaluations were started. At 30 days after sowing, plant height, stem diameter, height/diameter ratio, root length, shoot dry mass, root dry mass, total dry mass and Dickson Quality Index were evaluated. Data were subjected to analysis of variance and when significance was found by the F test, the cultivars averages were compared by Tukey test at a significance level of 5%. For the composting times regression was performed. Melon seedlings cv. Melão Amarelo presents better development than melon cv. Gaúcho Casca de Carvalho. The composting period of 120 days is the most suitable for the production of substrate for melon seedlings. [ABSTRACT FROM AUTHOR]

The purpose of this work is to identify variables relevant to the copper price formation process in the international market. Thus, hypothesis statistical tests and other statistical procedures were carried out to verify the historical relevance and the intensity of the impact of selected variables on the copper price. Among these variables, the global industrial production and the aluminum price in the international market presented the greatest evidence of being relevant to the formation of the copper price in the international market. In addition, the results obtained suggest that the copper stocks, exchange rate and crude oil price variables should be also considered. The information used in this research was monthly data from January 2009 to December 2015. [ABSTRACT FROM AUTHOR]

This contribution delves into the investigation of cohesive devices in original and translated texts by querying the impact of text and language typologies on the frequency of conjunctions (NUNES, 2014). Data was obtained in the Corpus de Língua Portuguesa em Tradução, a bilingual bidirectional parallel corpus in the language pair English-Brazilian Portuguese. The corpus is comprised of eight text types: research article, political speech, science popularisation, fiction, instruction manual, tourism leaflet, review and educational website. TreeTagger was used for POS tagging and R environment utilized to perform automatic word frequency and significance testing. The results showed highly above expected frequencies in reviews and in political speeches, thus corroborating explicitation hypotheses as to the frequency of cohesive marks in argumentative texts. Also, the explicitation hypothesis as to significantly above expected frequencies of conjunctions in translated texts and in the original and translated texts in Brazilian Portuguese was partially corroborated. Findings also showed relevance in statistically significant frequencies in fictional and educational website texts. As to the former, a tendency for the explicitation of conjunctions in original and translated texts in Brazilian Portuguese was revealed. Conversely, frequencies in the latter pointed to a tendency for the explicitation of conjunctive marks in translated texts in English. The findings mostly contribute to descriptive translation studies concerning language description of English and Brazilian Portuguese in their written modes. [ABSTRACT FROM AUTHOR]

Meal production involves processes that cause environmental impacts. Improving these factors is a challenge for managers who need to reconcile these aspects with clients' costs and needs. The objective of the study was to evaluate the environmental sustainability in food services and the nutritionist's perception in this regard. A check list was applied to obtain sustainability aspects and a questionnaire to evaluate the perception of the nutritionist, both with a score of up to 100%. The data were analyzed by mean and standard deviation. Student's t-test was used to analyze the difference between two means and analysis of variance (ANOVA) to analyze the difference among three or more means. The analyses of association between two quantitative variables were performed using the Pearson's correlation. All statistical tests considered a significance level of 5%. Of the total of restaurants (n=7), 71.4% (n = 5) had programs focused on environmental sustainability. Only one (14.3%) had a score of 77.4% on the sustainability check list, being classified as "good" and 85.7% (n = 6) presented a score of 50 to 74%, with a score of "acceptable ". Places with sustainability-focused programs had higher scores. A weak correlation was obtained when analyzing the association between the perception of sustainability and the check list score. It was possible to verify that most nutritionists have a high perception about sustainability, but observing the check list scores, it is noticed that few actions are taken in order to minimize the environmental impact.

The purpose of the study was to evaluate the behavioral changes of male and female adult rats exposed to fine and ultrafine particulate matter (PM≤2,5) suspended in air pollution during development. Wistar rats aged 7 postnatal days were exposed to the chamber of an atmospheric particle concentrator. Open field tests and sucrose preference tests were performed to assess the presence of anxiety and depression behaviors. Male rats from the pollution group showed reduced locomotor activity and length of stay in the open field center when compared to the control group. The sucrose preference test showed statistical significance between the pollution and control groups (male+female), and among the males of the pollution and control group. The study concluded that exposure to PM≤2.5 causes behavioral changes characteristic of depression and anxiety in adult male rats exposed during the developmental period. [ABSTRACT FROM AUTHOR]

Objective: to evaluate the access and its interference in the process of selfmedication in the elderly. Method: evaluation study of cross-sectional services with elderly men and women who use primary health care services in the city of Natal, Rio Grande do Norte. A total of 121 interviews were conducted in 09 basic health units of the municipality in 2016. Data were analyzed using the Student's ttest and chi-square test to determine the statistical significance between the two independent variables and outcomes. Results: the prevalence of self-medication was 66.7%, being negatively associated with access, a negatively assessed attribute in the perception of the elderly, showing an unsatisfactory degree (mean of 3.4). Fever (19.8%) was the main motivating complaint of self-medication, with analgesics being the most used self-medication. Self-medication showed a significant association between age and nonprescription medication for fever and headache. Conclusion: despite not finding an association between access and selfmedication, the high prevalence of this practice was identified. Thus, it is necessary to strengthen primary care through policies focused on the needs of the elderly with a comprehensive approach and greater access to multidisciplinary and multiprofessional care, not just the supply of medicines.

The current study was carried out to evaluate the quality of raw milk, in rainy and dry seasons in 2012, 2013 and 2014, in Goiás State, Brazil, by means of the hygienic-sanitary indicators TBC and SCC, comparing with the legal limits of the Normative. A total of 1,600 dairy herds of Goias State, that constitute the database of the Milk Quality Laboratory, were evaluated. Monthly data regarding TBC and SCC were analyzed. Explanatory variables were associated to time (years 2012 to 2014) and period (rainy and dry season). For statistical analysis, Scott Knott test at 5% significance was employed. There was statistical difference (p>0.05) when rainy and dry periods were compared along the years 2012 and 2013 for TBC and SCC. Geometric mean of TBC and SCC in 2012, 2013 and 2014 were within the legal range of 300,000 CFU/mL and 500,000 Cells/mL, but 23% and 21% of the herds, respectively, were above the legal range. The findings of this study reveal milk quality is highly affected by seasonal variations, i.e., rainy and dry seasons, indicating the need of a more effective control during the rainy period.

Current study evaluates the economic viability of ducks fed on phase nutrition plans at different population densities. Two hundred and forty native dusks were used within a totally randomized design in a 3x2 factorial scheme, with three nutritional plans (3,4 and 5 phases) and two pen densities (2 and 3 fowls/m²), with four replications with 10 ducks each. Performance of ducks was evaluated weekly. After 90 days, four ducks from each treatment were slaughtered to analyze meat production. Data were analyzed by Tukey's test at 5% significance. Significant differences (p<0.05) were observed for total feed consumption, feed conversion, feed costs and balance point between nutrition plans where, ducks fed at reduced phases (3 phases), had the best results. There were significant differences (p<0.05) between pen densities for consumption of total feed, weight at finish, feed costs, meat production (kg and kg/m²), production costs (kg and kg/m²) and equilibrium point, with the recommendation of 2 ducks/m² for the best results. Results show that confined ducks submitted to nutrition plans with reduced phases (3 phases) and pen densities of 2 ducks/m² provided the best performance, meat production and profitability. Further studies are required to determine other technical requirements for confined ducks. [ABSTRACT FROM AUTHOR]

Objectives: to identify the factors associated with hypovitaminosis A in children in the semi-arid region of the Brazilian State of Alagoas. Methods: a cross-sectional study was carried out with a probabilistic sample of 551 children aged under five years. Serum levels of retinol were measured using high-efficiency liquid chromatography. In order to identify any associations between the independent variables and hypovitaminosis A (retinol <20 μg/dL) the prevalence ration (PR) was used with a confidence interval of 95% calculated using the Poisson regression, with a robust adjustment for variance, both in the raw analysis and in the adjusted one. The latter included all the variables from the raw analysis for which p<0.1. Associations were considered statistically significant when p< 0.05. Results: the prevalence of hypovitaminosis A was 45.4% and the variables that remained associated in the multivariable analysis were low maternal schooling (PR=1.66; CI95%: 1.12-2.44), low birth weight (RP=1,41; 1C95%: 1,01-1,98) and being aged between 12.1 and 24 months (PR=1.45; CI95%: 1.04-2.02). Conclusions: this reveals that hypovitaminosis A is epidemiologically significant in children in the semi-arid region of Alagoas. Low birth weight newborns in the second year of life, born to mothers with a low level of education, should therefore receive priority health care. [ABSTRACT FROM AUTHOR]

Purpose: to investigate the relation between time and type of feeding with chewing, swallowing and breathing functions. Method: the sample consisted of 52 children of both genders, aged between 5 and 8 year-old. Through a questionnaire, we collected data regarding type and duration of children's breastfeeding and breathing. The children were submitted to clinical evaluation of functions, based on the Orofacial Myofunctional Assessment Protocol with Expanded Scores (AMIOFE-E). Data were descriptively and statistically analyzed. For testing the normality of the quantitative variable, we used the Lilliefors test. All relations among the variables were checked through Chi-square test, considering a 5% significance level. Results: there was no statistically significant relation between duration and type of feeding and breathing and swallowing variables. There was a statistical significance between feeding type and chewing, but not between feeding duration and this variable. Furthermore, the significant relation failed to follow the expected pattern. Conclusion: it was possible to conclude that, generally, there was no significant relation between time and type of feeding and the investigated functions, except for the significance between type of feeding and chewing. Probably, the lack of significance is due to the fact that the development of all the stomatognathic system has multifactorial sources. The statistical significance found as for the chewing function, since it showed an unexpected pattern, may have occurred because of the restricted number of subjects in each subgroup.

Purpose: to investigate the life quality of subjects with mouth or oronasal breathing. Method: the sampling was composed of 49 volunteers distributed into 2 groups: mouth breathing subjects' group with 24 subjects and oronasal breathing subjects' group (mouth and nose) with 25 subjects, within the 18-38 age group, both genders. The WHOQOL-BREF (Portuguese version) protocol was used and the data analysis and recording were carried out using the Statistical Analysis System. Results: the obtained results underwent Mantel-Haenszel chi-square test and variance analysis. Life quality in oronasal breathing subjects was demonstrated to be better in environmental, physical and psychological domain in relation to mouth breathing subjects. Conclusion: considering the obtained differences, the study draws attention to the need for better investigating the profile of oronasal breathing subjects and its relevance, so that the conducts, such as disregarding the group of oronasal breathing subjects or gathering them as mouth breathing subjects, are not improperly adopted.

In order to test the hypothesis that digital literacy skills improve the elderly cognitive performance, more specifically episodic and working memory, meta-memory, and auto-efficacy in memory, two experimental groups (EG) were created. The groups were formed with a total of 22 elderly people who participated in a workshop on Digital Inclusion. The constructs were assessed in pre- and post-activities. EG performance was compared to a control group (CG) composed by other 16 elderly participants. After 19 workshops of two hours each, the changes in cognitive processes of the elderly which were observed in this research cannot be assigned to the educational process evaluated. The limitations of the quasi experiment and scientific and social implications of the results are also analyzed. [ABSTRACT FROM AUTHOR]

The Big Five model sustains that human personality is composed by dozens of specific factors. Despite of diversity, specific factors are integrated in five broad traits that are in the same hierarchical level. The current study presents an alternative hypothesis arguing that there are hierarchical levels between the broad traits of the model. Six hundred and eighty-four junior and high school level students from 10 to 18 years old (M = 13.71 and SD= 2.11) of a private school in the city of Belo Horizonte, Minas Gerais, Brazil participated in the study. The Big Five was measured by an Inventory of Personality Traits, initially named as Personality Adjective Inventory, elaborated by Pinheiro, Gomes and Braga (2009). This instrument measures eight polarities of the ten presented in the Big Five Model. Two models were compared through path analysis: a four-level hierarchical model and a non-hierarchical one. The hierarchical model showed adequate data fit, pointing to its superiority in relation to the non-hierarchical model, which did not present it. Implications to the Big Five Model are discussed.

This study is part of the Project entitled "Relevance Theory and Socio-Rhetorical Genre Analysis," which aims to analyze the theoretical and conceptual interfaces of these approaches based on journalistic genre corpora. In this paper, we evaluate the correlations between front-page texts and inner texts, arguing that ostensive stimuli of both front-page and inner text headlines and leads form a whole with the inner text itself. The former texts guide the focal scale elements of the latter ones. In order to deal with this hypothesis, we highlighted the 27th front-page text, and the 33rd inner text of Caldeira (2007, p. 77 and 114) on the prohibition of outdoor advertising in São Paulo, collected from September 27, 2006 edition of Folha de S.

The atmosphere of a store can be used to produce specific emotions that enhance purchase probability, and the ambient scent, artificially added, is among its dimensions. This article investigates the relationship between the presence of an ambient scent in a retail store, and customers' evaluation of the store, its environment and products, as well as the behavioral intentions related to return and time spent in the store. The research design included an exploratory stage, examination of publications in the fields of physiology, psychology and consumer behavior, to provide the conceptual background and to formulate research hypothesis; and a causal stage, quasi-experiment, to verify the effects of scent presence. Semantic differential scales were employed for data collection. Descriptive statistics and hypothesis test were performed for data analysis and the results revealed that the scent presence did not improve the evaluations or the intent to return but retained the consumer longer in the store.

Based on the assumption that trust is a mechanism of relational governance, which can influence the costs associated with the formation, development and maintenance of interorganizational relationships, in this article one aims to test the relation between trust and transaction costs in these relationships. Based on the literature on trust and on transaction costs, one puts forward four new hypotheses, which suggest a negative relation between trust and costs of information, of negotiation, of implementation and of monitoring in interorganizational relationships. These hypotheses were tested using multiple regression analysis in a quantitative case study where the buyer is illustrated by an automaker and its suppliers are represented by a sample of the major ones. The results suggest that there are significant, yet negative relations between trust and costs of negotiation and of monitoring. The relations between trust and costs of information and of implementation, in turn, are not statistically significant. We believe that these results represent a more-fined grained understanding of the relation between trust and transaction costs in interorganizational relationships to the degree that it is suggested that the four types of transaction costs are not perfectly correlated.

The main objective of this study is to assess the effect of parent brand perceived quality and perceived similarity on the evaluation of corporate service brand extensions. It is also the intention of this study to verify whether providing information cues about the characteristics of the extension contributes to the brand extension evaluation. The hypotheses were tested by means of three experiments involving 1,131 subjects. The results of Study 1, conducted with fictitious brands as stimuli, demonstrated that the perceived quality of the parent brand played a more significant role than perceived similarity on the evaluations of brand extensions. In Study 2, where real brands were used as stimuli, the results were the same as in Study 1. Study 3 found that providing information cues about the characteristics of the extensions had a positive effect for one of the extensions of the high quality parent brand but not for the two proposed extensions of the low quality parent brand. Taken as a whole, the results suggest that the perceived quality of the parent-brand plays a fundamental role in the evaluation of corporate service brand extensions. The study also contributes several hypotheses for future studies and managerial implications for managers of corporate service brands. [ABSTRACT FROM AUTHOR]

Based on the work of Entwistle and colleagues about how students perceive and live learning experiences, the main aims of the present study were: first, to understand and to analyze meanings attributed to learning, to study and preferences for types of teaching, in order to understand how students conceptualize what is required from them in terms of learning in Higher Education; second, to understand if students' approaches to studying and conceptions of learning differ according to the scientific areas and course years. Furthermore, if differences were found, our intention was to analyze its meanings, what seems most relevant in terms of learning pathways for those involved. In this sense, we considered the perceptions of students regarding teaching and learning, as indicators that influence what students think about teaching, studying and learning (preferences for types of lectures and teaching). Considering the proximity between constructs we wanted to further relate the approaches to learning with the conceptions of learning (reproductive and significant) and, the preference for diversified types of learning and of instructions. It was also our intention to set profiles according to the ways the students approach study and learning. This descriptive, correlational and non experimental study design was developed with a sample of 568 students at a university in the south of a European country. The results supported the hypothesis that there are some significant differences in terms of year of course and of the scientific domain, and allowed us to set profiles according to the ways students perceive study and learning tasks.

In vitro mycelium growth of five Agaricus bisporus strains submitted to different temperature conditions. The in vitro mycelium growth of Agaricus bisporus strains AB1-05/03, ABI-06/04, ABI-04/02, ABI-06/05 and ABI-01/01 was evaluated in solid culture media made up of compost. Evaluations were performed by means of measurements of four diameters of the colonies, every 48 hours, during 12 days of incubation in darkness under 20 and 25°C. The experimental design consisted of randomized blocks, using the Tukey test to compare averages. Based on the obtained results, it was verified that: mycelium growth of A. bisporus is influenced by the temperature of incubation; the temperature of 25°C was more favorable to the mycelium growth of all A. bisporus strains; under the temperature of 20°C, the best growth was obtained with strains ABI-06/05 and ABI-01/01 and, under the temperature of 25°C. strain ABI-01/01 showed significantly higher growth than all other strains.

Background: Chronic venous disease afflicts individuals in their most productive years, resulting in pain and loss of mobility and independence in performing routine daily activities, which may directly interfere with the patient's quality of life. Clinical symptoms result from venous hypertension caused by reflux and/or venous blockage. Objective: To determine differences in the quality of life of patients with mild and severe chronic venous disease. Methods: A cross-sectional comparative study was conducted in a health care facility during an 8-month period. The sample was composed of 88 patients divided into two groups: group A (clinical CEAP class 1, 2 and 3) and group B (clinical CEAP class 4, 5 and 6). The Medical Outcomes Study - 36-Item Short-Form Health Survey (SF-36) questionnaire was used. Statistical analysis was conducted using the Student t test, with a 95% confidence interval and a level of significance set at p < 0.05. Results: We analyzed 88 subjects, 47 in group A and 41 in group B. Of the total, 87.5% (77) were women and 34% (30) were aged 30 to 40 years. Subcutaneous changes (CEAP class 4) were the most common symptoms, observed in 28.4% of the individuals. Except for the general health perceptions domain, group B showed lower scores than group A in all other domains. Conclusions: The quality of life of patients with mild and severe chronic venous disease proved to be different according to disease severity. [ABSTRACT FROM AUTHOR]

The objective of this study was to evaluate the effect of three fertilizer-seeders, in ground conventionally prepared and five densities of plants in the row in soybean yield and agronomic characteristics. The sowing was carried through in years 2001/2002 and 2002/2003, with Monarca and Conquista cultivars. Fertilizer-seeders were used, being two precision seeders and a one seed drills and manual sowing (witness). The experimental design was randomized blocks, with three replications, and treatments in split plots. Accuracy in plant spacing in the row, grains yield, pods for plant, mass of 100 grains, plants height, lodging and real density of plants in the row had been evaluated. The precision seeder with vacuum metering system provided larger accuracy and grains yield, in relation the mechanical metering system, in the densities from 10 to 19 plants m-1; in the 22 plants m-1 density it did not have difference between the precision seeders with regard to yield; the seed drills, with the conformation used in this work, was not adjusted for the implantation of the soybean crop.

The objective of this study was to estimate the base temperature for leaf appearance and the phyllochron of a maize variety in several sowing dates and two growing seasons. A field experiment was conducted in Santa Maria, RS, with seven sowing dates using the BRS Missões variety in two growing seasons (2005-06 and 2006-07). The experimental design was a completely randomized blocks, with six replications. Plots were three 5 m rows in a 0.8m x 0.21m spacing. Three plants in the central row of each plot were randomly tagged, and the number of fully expanded leaves (NFE) and the number of leaf tips (NFT) were counted once a week on the tagged plants. The base temperature varied with sowing date from 4.5 to 12°C and an average of about 8°C was used to calculate thermal time. Phyllochron was higher when calculated on an NFE basis than on a NFT basis, and varied with sowing date from 50.0 to 69.9°C day leaf-1 and from 39.6 to 59.8°C day leaf-1, respectively, with photoperiod being a likely cause to explain the variation in the phyllochron with sowing date.

The objective of this trial was evaluated the effect of different crude protein (CP) levels of diet for males with or without coumbing. Body weight, semen volume, number of spermatic cells and fertility were evaluated. A total of 32 males Cobb 500 were used being 50% coumbed and 50% decoumbed males. The roosters were exposed the same management conditions in starting and rearing phases. They were housed in individual metallic cages with feeders and drinkers. The experimental design was entirely casualized in a factorial 2x2, two comb conditions (with or without) and two levels of crude protein (12 and 16%). Semen was collected using the American methods and number of spermatic cells was determined by counting in Neubauer chamber. At 42, 43 and 44 weeks of age, six females were artificially inseminated by treatment, twice a week, with dosage of 0.05ml of fresh semen. The eggs were collected four times a day, identified, disinfected and incubated in similar conditions. After 21 day of incubation they were broken and examined macroscopically to analyze the fertility. The level of 12% of crude protein was enough to assist the reproductive demands and the permanence of males. Combed males had body weight higher than without combed males. [ABSTRACT FROM AUTHOR]

The analysis of genotype x environment interaction in plant breeding have been enlarged with new methodologies in the last decade, improving its efficiency on the selection of genotypes under different environmental conditions. The objective of this research was to analyze the yield and stability of twelve genotypes of rice, in eight environments, during the years 2005 and 2006 in Colombia. Completely randomized block designs with four replications were used. The phenotypic stability parameters and grouping of environments were estimated by the genotype-environment interaction study according to SREG (Sites Regression) method and its biplot graphic (GGE). The statistical analysis indicated significant differences (with 5% probability error) among genotypes and among environments. Also, it pointed out the significance (with 5% probability error) of the genotype-environment interaction, indicating different responses of genotypes confronted with different environments. In SREG method, the two first principal components of interactions explained 75.29% of the interaction. The genotypes 400094, 350361 and the variety Fedearroz were found as the highest yields. According to the biplot GGE graphic the environments La Libertad and Escobal were the ones with small variations during the years of study. [ABSTRACT FROM AUTHOR]

The statistical techniques and statistical accessibility were analyzed in a sample collected from the original articles published between 1996 and 2006 by two fruticulture journals: the Revista Brasileira de Fruticultura (RBF) and the French journal Fruits. A total of 986 original articles were classified in 16 classes of statistical analyses, previously ordered by increasing degree of complexity. The complexity of statistical techniques used by both journals increased in time. Along the 1996-2006 period, the articles published in the RBF journal utilized more complex statistical techniques, as well as experimental designs in randomized blocks, factorial, split plot and hierarchical arrangements, and the test of Tukey for mean comparisons. In the articles published by the Fruits journal the use of other parametrical tests and the Duncan test was more frequent. In both journals the SAS statistical software was most frequently utilized. Readers of the RBF journal required a higher level of statistical knowledge to understand the techniques utilized in the articles. [ABSTRACT FROM AUTHOR]
