title: Effect of climate and geographical conditions on the occurrence of cashew gummosis in the northeast of Brazil

description: ABSTRACT Cashew gummosis is one of the main diseases of the cashew in the semi-arid region of the northeast and is characterised by a decline in the plants and a reduction in stand. Lasiodiplodia theobromae, the causal agent, is an endophytic fungus that eventually takes on pathogenic characteristics; however, the environmental conditions that cause this change in behaviour are still unknown. It is assumed that stress in the host caused by environmental changes stimulate pathogenicity. The aim of this study was to define the relationship between climate and geographical factors and the occurrence of gummosis. Rainfall data, maximum and minimum temperature, thermal amplitude, and the altitude of 14 micro-regions in the northeast were compared and classified into five frequencies of disease occurrence: 0 (no occurrence), 1 (rare occurrence), 2 (frequent occurrence), 3 ( generalised occurrence) and 4 (generalised high-severity occurrence). The data were submitted to the Doornik-Hansen test for multivariate normality, and principal component analysis was carried out using the correlation matrix between the climate and geographical variables and occurrence of the disease. Areas of disease severity were correlated (Pearson’s correlation). Only thermal amplitude, altitude and latitude were associated with the different areas of gummosis occurrence. The districts of Buíque, in the state of Pernambuco, and São Raimundo Nonato, Canto do Buriti and Pio IX, in Piauí, with the highest incidence of the disease, had the highest values for thermal amplitude, altitude and latitude. Whereas the districts of Pacajus and Beberibe had a lower occurrence of gummosis, with lower values for thermal amplitude, altitude and latitude.

title: Morphological study of squash seeds at different stages of maturation through the use of X-ray

description: ABSTRACT Analysis of images has been recently used in order to both assess seed quality and elucidate some aspects of seed physiology, including X-ray tests and other resources. The objective of this study was to examine whether the X-ray may be successfully used to detect physical abnormalities, and relate their occurrence with physiological potential of tetsukabuto type squash seeds. Fruits were harvested at different maturation stages (15, 30, 45, 60 and 75 days after anthesis - DAA) and temporarily or not stored for 20 days. Seeds were radiographed using an intensity of 25 kV for 40 seconds and then germinated under alternating temperatures of 20-30 ºC. After four and eight days, percentages of normal and abnormal seedlings and dead seeds were recorded. Results of both counts were evaluated comparatively with images of the internal morphology of each seed, obtained by means of X-ray test. The radiographic analysis is effective in detecting full, malformed and empty squash seeds. This confirmed information provided by the germination test, in which seeds harvested from 60 DAA and stored for 20 days were better in physiological potential.

title: Acute toxicity of non-ionized ammonia on tambacu (Colossoma macropomum x Piaractus mesopotamicus)

description: ABSTRACT Ammonia is a toxic compound to aquatic organisms and at high concentrations in water, it can cause various changes in the animal. Therefore, it becomes important to determine the tolerance of farmed aquatic animals for that substance. Thus, the aim of this study was to determine the mean lethal concentration (LC50-96 h) of un-ionized ammonia (NH3) in tambacu fingerlings (Colossoma macropomum x Piaractus mesopotamicus) in acute toxicity test. The fingerlings were exposed to ammonia at concentrations of: 0.09 (control); 0.54; 1.23; 2.52; 3.44 and 3.66 mg L-1 NH3, which were obtained from the application of NH4Cl. The test lasted 96 hours and mortalities were recorded over that period. The LC50 was determined by the Trimmed Spearman Karber statistical method. The LC50-96 h of non-ionized ammonia (NH3) for fingerlings of the tambacu hybrid was 1.63 mg L-1.

title: Nitrogen utilization efficiency by naturally colored cotton cultivars in semi-arid region

description: ABSTRACT Knowledge on nitrogen (N) utilization efficiency in colored cotton enables the correct management of N fertilizers, optimizing yield and minimizing environmental degradation.The objective of this study was to evaluate the N utilization efficiency and to determine the accumulation of dry matter and N by naturally colored cotton cultivars subjected to N fertilization in the Brazilian semi-arid region.The experiment was carried out under field conditions, at the Farm of the Federal Rural University of the Semi-Arid, in 2016 and 2017. The experimental design was in randomized blocks with split plots and four replicates, randomizing five N doses (0; 50; 100; 150 and 200 kg ha-1) in the main plot and four colored cotton cultivars (BRS Safira, BRS Rubi, BRS Topázio and BRS Verde) in the subplots. Dry matter and N accumulations, agronomic, recovery, agrophysiological and physiological efficiencies in N utilization, and harvest index were evaluated. Cotton accumulates around 130 kg ha-1 of N along its cycle and directs 56.3% to seeds, 29% to leaves, 10.6% to stem and 3.8% to fibers. Nitrogen agronomic efficiency and recovery efficiency decrease with increased N doses. The cultivar BRS Topázio is the most responsive to N fertilization and the cultivar BRS Verde is the least responsive.

title: Digital evaluation of the influence of interruption of the fixation process on radiographic contrast and base-plus-fog density in three commercial brands of radiographic films

description: INTRODUCTION : With the interest in anticipating access to the result of intraoral radiography, the radiographic processing is frequently neglected, compromising image quality. OBJECTIVE : The aim of this study was to evaluate the influence of interrupting the fixation process on the radiographic contrast and base-plus-fog density (BPFD) in three brands of periapical films. MATERIAL AND METHOD : Ninety radiographs were taken of an aluminum stepwedge and a lead plate for each brand, and they were divided according to the time of initial immersion in the fixative in: control group (without interrupting the fixing), 5, 10, 20, 30 and 40 seconds. During processing, films had the fixing stage stopped and were exposed to a negatoscope for 1 minute, then the fixation time of 10 minutes was completed. The radiographs were digitized and exported to Image Tool 3.0.software. RESULT : Kodak(r) film showed no statistically significant differences between groups, while Agfa(r) film presented difference in BPFD compared with Group 5 seconds, and Dentix(r) film showed statistical difference in all groups in comparison with the control group. CONCLUSION : Under the conditions studied, Kodak(r) film is not influenced by disruption of fixation as regards BPFD and image contrast, enabling early access to the results of radiographs, whereas Agfa(r) film requires at least 10 seconds of initial fixation, and Dentix(r) film obtains better results when the process of fixation is not interrupted.

title: Professional profile of dentists who are members of the Family Health Strategy city of Marília, São Paulo: the challenge of interprofessional work

description: INTRODUCTION: The inclusion of oral health professionals within the Family Health Strategy was legislated in December, 2000, by the Ministery of Health. These professionals are included in a new context which challenges the traditional education of fragmented knowledge and presents the challenge of interprofessional work. OBJECTIVE: To analyze the profile and the interprofessional practice of dentists working in the FHS in the city of Marília, São Paulo. MATERIAL AND METHOD: In 2012, a structured questionnaire and an adaptation of the Readiness Interprofissional Learning Scale (RIPLS), given to 34 dentists working in the FHS in the city of Marília, São Paulo, were used to collect data. Descriptive statistics and the nonparametric Kruskal-Wallis analysis of variance with SNK multiple comparisons post-test, at a significance level of p &lt; 0.05, were used for data analysis. RESULT: The dentists are in the 31 to 40 year age range (70.6%), are mostly women (82.4%) and 79.41% hold a specialization in Public and Family Health. Comparisons of the differences of the mean scores of the responses among professionals, with and without graduate study in this area, were statistically significant in the statements regarding the amount of human resources and interprofessional work. CONCLUSION: Graduate study in Public and Family Health provides dentists with background on the integration of teamwork, the understanding about the process of interprofessional work, the enhancement of common and collaborative professional skills and thus minimizes the effects of an incomplete health team. It is considered that professionals without graduate study are restricted to their traditional and reductionist preparation.

title: Demographic and clinical manifestations of oral in patients seropositive for HIV /SIDA

description: INTRODUCTION: The oral and perioral lesions are common in patients infected with HIV, and may represent the first signs of the disease, even before the systemic manifestations. OBJECTIVE : This study aimed to estimate the prevalence of oral manifestations in HIV seropositive individuals, considering the aspects socio-demographic, immunological and therapeutic. MATERIAL AND METHOD: Was performed nature study clinical-epidemiological transverse, between October 2007 to April 2008, with a sample of 40 patients. Was used the technique of intensive direct observation through appropriate clinical exam. Data were recorded on data sheets pre-prepared and analyzed by descriptive and inferential statistics. RESULT: There was a prevalence of females (52.5%), aged 40-49 years (45%). Treatment with antiretroviral drugs was found in 85.0% of cases, all being with high power therapy (HAART). It was observed that 52.5% of patients had a TCD4+ lymphocyte count above 500cél/mm ³ and 50.0% had an undetectable viral load. The prevalence of oral manifestations was 42.5%, the most significant for pseudomembranous candidiasis (19.23%), followed necrotizing ulcerative periodontitis (15.38%), hairy leukoplakia (11.54%) and angular cheilitis (11.54%). No association was observed between oral lesions and viral load (p=0.1268) nor the TCD4 cell count (p=0.3458). CONCLUSION: Prevalence of some oral manifestations associated with HIV infection is still high, with pseudomembranous candidiasis infection more prevalent, mainly among people with low education levels and longer HIV infection, independent of the therapy and immune status of the patient.
