Efeito de épocas de colheita e período de repouso pós-colheita sobre as características físicas de frutos e sementes de mamoneira

This study aimed to assess the effect of harvesting times and of post-harvest resting period on physical characteristics of fruits and seeds of castor bean (AL Guarany 2002 genotype) and to verify if theses characteristics could be used to identify the ideal harvest time. Nine times of raceme harvest were assessed from 30 to the 142 days after anthesis (DAA) at fourteen days intervals, and four conditions of resting; (without and with seven days of resting period of seeds extracted (bare), from fruits and fixed to the racemes). It was evaluated water content, seed thickness, and length, width, and weight of fresh fruits and seeds, and seedling emergence in sand. The statistical design was completely randomized with four replications. The harvest times and the post-harvest rest period affected the physical characteristics of fruits and seeds of castor bean but none of these have proved to be effective in the identification of the ideal harvest time.

Validação de conteúdo do instrumento para consulta de enfermagem na visita domiciliar às pessoas com lesão medular: um enfoque no autocuidado

This study aimed to validate the contents of an Instrument for Nursing Consultation in the Home Visit of people with Spinal Cord Injury (INCEVDOP-LM), based on the Self-Care Deficit Theory. The methodological development study was conducted with spinal cord injured (SCI) people ascribed in the Family Health Units the city of Natal/RN/Brazil, and with the nurses of these institutions. The study was conducted from Januray 2012 to January 2013 in two phases: the first aimed to identify the need for self-care of persons with SCI, and the second to develop and validate the INCEVDOP-LM. The first phase consisted of a census study of people with SCI living in Natal/RN. In the second phase, a non-probabilistic convencience sample of subjects was selected to form two groups: First stage - Group 1 of the first stage was comprised by 73 adults with SCI diagnosed with paraplegia or tetraplegia, with cognitive function preserved and that were registered to some family health unit; Group 2 of the Second phase was composed of six experts that were nurses with doctoral formation, scientific experience in the area of technology development or assistance to persons with SCI, and with publications in periodicals Qualis A2. Data collection of the first phase was conducted through home visits of people with SCI that responded three instruments: Questionnaire I (comprised of demographic and socioeconomic variables), The Competency Rating Scale for Self-care (ASA) and the Barthel Index (an instrument for evaluation of functional capacity). The research for the second phase was conducted in two stages: I-construction of the INCEVDOP LM; II-validation of the INCEVDOP-LM. The instrument and an evaluation form were forwarded to the experts for the validation. The correlations between the responses were analyzed by the Kappa test, with accepting values of>0.75. The evaluation criteria were: organization, clarity, simplicity, readability, appropriateness of vocabulary, objectivity, accuracy, reliability and suitability and the positive responses with frequency values of≥90% were considered excellent. The chi-square test was used to investigate the differences between proportions. The study attended to the principles of Human Rights CNS Resolution 196/96. Results were reported by means of four articles derived from the study. The findings indicate that the items that showed disagreement among experts (k=0.02) were diagnoses, interventions and evaluation of the nursing features pertaining to the domains of Nutrition, Hygiene, Elimination, Physical, Social and Psychological, and of the Ability to perform work activities feature. Agreement among the experts were reported for the other items, with kappa ranging from 0.72 to 1. After removing items with disagreement, all criteria achieved excellent rates and no significant differences were observed between the proportions of responses of evaluation of experts (p>0.05). We conclude that the instrument shows validity to serve as a guide for nurses to conduct a systematic consultation during the home visit to people with spinal cord injury, with emphasis on self-care. The instrument must go through other levels of validation when applied in the clinical setting

Influência do manejo do solo nas propriedades químicas e físicas em topossequência na bacia do rio Araguaia, Estado do Tocantins

A conversão do Cerrado nativo em áreas de exploração agrícola pode modificar os processos de decomposição e síntese da matéria orgânica do solo e, assim, na disponibilidade de nutrientes. Objetivou-se avaliar as propriedades químicas e físicas do solo em topossequência caracterizada por apresentar uso com pastagem cultivada com Brachiaria brizantha ao lado do Cerrado nativo, na camada de 0- 15 cm de profundidade. O estudo foi realizado no município de Colmeia, Estado do Tocantins. Foram determinados 10 pontos de coleta (cinco para Cerrado nativo e cinco para pasto) para cada posição do relevo (topo, encosta e pedimento); em cada ponto amostral, foram coletados solos em três profundidades (0-5, 5-10 e 10- 15 cm), totalizando 90 amostras. Foram realizadas as seguintes análises químicas e físicas: C orgânico, P, K+, Ca2+, Mg2+, H + Al, pH e granulometria. O C orgânico não apresentou diferença (p > 0,05) entre os valores encontrados no Cerrado nativo e pastagem e as posições do relevo avaliadas. A conversão de Cerrado nativo para uso agropecuário reduziu os teores de P. Os teores de K trocável não foram alterados pela retirada da cobertura vegetal original. Observou-se aumento dos teores de areia quando se passou da meia-encosta para o pedimento.

Efeitos da subsolagem e da adubação verde nas propriedades físicas do solo em pomar de citros

O presente trabalho teve por objetivo avaliar o efeito da subsolagem e da adubação verde nas propriedades físicas de um Latossolo Vermelho distrófico típico, cultivado com citros (laranjeira Valência). Os tratamentos empregados foram: manejo mecânico das plantas invasoras com roçadora (Testemunha); subsolagem em um lado da planta na entrecopa; subsolagem nos dois lados da planta na entrecopa, e semeadura direta de Crotalaria spectabilis na entrecopa. As propriedades físicas do solo avaliadas foram: porosidade total, macroporosidade, microporosidade, densidade, resistência mecânica à penetração vertical e condutividade hidráulica. Na avaliação efetuada na safra 2001-2002, obtiveram-se os maiores valores de densidade do solo e resistência do solo à penetração vertical, e os menores valores de macroporos e condutividade hidráulica do solo nas entrecopas com e sem tráfego no pomar, em relação à região da copa, principalmente na camada de 0,0-0,2 m de profundidade. Os tratamentos aplicados não surtiram efeitos positivos significativos nas propriedades físicas do solo.

Efeito prolongado de sistemas de preparo do solo com e sem cultivo de soqueira de cana crua em algumas propriedades físicas do solo

Este trabalho foi conduzido em Latossolo Vermelho distrófico típico, sob cultivo de cana crua, com o objetivo de avaliar o efeito prolongado de sistemas de preparo do solo, com e sem cultivo da soqueira, e épocas de amostragem sobre algumas propriedades físicas do solo. O delineamento experimental foi o de blocos ao acaso, em esquema de parcelas subsubdivididas, sendo os tratamentos principais quatro sistemas de preparo do solo: (i) controle da soqueira com duas gradagens, subsolagem e mais uma gradagem de nivelamento; (ii) controle da soqueira com herbicida e uma subsolagem; (iii) controle da soqueira com herbicida; (iv) controle da soqueira com herbicida, aração com arado de aivecas e uma gradagem de nivelamento. Os tratamentos secundários foram: com cultivo e sem cultivo da soqueira. Os tratamentos ternários foram as épocas de avaliação: dois dias antes e após a quarta colheita da cultura. A porosidade total, macroporosidade, microporosidade e densidade do solo foram avaliadas, além do perfilhamento e da produtividade da cultura. Após quatro sucessivas colheitas de cana crua, houve redução da macroporosidade com aumento da microporosidade nas camadas abaixo de 10 cm e aumento da densidade do solo entre 20 e 50 cm. A densidade do solo não foi alterada de modo consistente em função de todos os tratamentos testados. O cultivo da soqueira favoreceu o aumento da macroporosidade com decréscimo na microporosidade, e o efeito inverso foi observado após a colheita. Os sistemas de preparo do solo e de cultivo da soqueira não afetaram o perfilhamento e a produtividade da cultura.

Evidências de validação de um protocolo para assistência às pessoas com úlceras venosas em serviços de alta complexidade

Venous ulcers are lesions resulting from chronic venous insufficiency, venous valvular abnormalities and venous thrombosis. Its occurrence has been growing with the increase in life expectancy of the world population. Considered as fundamental aspects in the approach to the person with venous ulcer care with the interdisciplinary approach, adoption of protocol-specific knowledge, technical skill, coordination between levels of care complexity of the Health System and active participation of patients and their families, a holistic perspective. The construction of a clinical protocol for people with venous ulcers can help professionals of high complexity services in patient assessment and the establishment of quality care in a systematic way and focused on the factors that interfere with wound healing. Thus, this study aimed to analyze the evidence of validation of a clinical protocol for people with venous ulcers treated at high-complexity services. This is a methodological study with a quantitative approach, developed in three stages: literature review, evidence of content validity and evidence of validation in the clinical context. Approved by the Federal University of Rio Grande do Norte Research Ethics Committee (Opinion: 147.452 and CAAE: 07556312.0.0000.5537). The literature review was conducted in August and September 2012, becoming the basis for the construction of the protocol. Then the evidence of content validity, which included 53 judges (experts) selected by the Lattes platform to evaluate the protocol items was performed. The judges were contacted by e-mail and rated the protocol via Google Docs . After analyzing the ratios obtained in this step, which reported kappa between 0.75 and 0.96 and between 0.80 and 0.98 IVC, and the suggestions of the judges, the protocol was adjusted and subjected to empirical evidence to validate the clinical setting at the University Hospital Onofre Lopes in Natal / RN. Evidence of validation in the clinical setting involved 4 judges who acted in pairs (paired) evaluated 32 patients with venous ulcers in the clinical context of high complexity. In both stages, we used the Kappa Index and Content Validity Index to analyze the responses of the judges. The parameters set as acceptable for these indices were: Kappa ≥ 0.61 and Content Validity Index > 0.80. Any evidence of content validity, as evidence of validation in the clinical context, the protocol items that have not reached Kappa and Content Validity Index established indices were excluded and some items were modified or added after suggestions. The process of content validation evidence and evidence of validation in the clinical setting allowed the improvement of the protocol for the care of people with venous ulcers initially proposed. The initial version of the protocol, built from the literature, contained 15 categories and 108 items; after evidence of content validity, remained the reduction to 15 categories with 91 items; the final version, clinically validated, is composed of the same 15 categories, 76 items. The protocol was validated in its content and in the clinical aspect, so we accepted the alternative hypothesis in the study. This protocol may contribute to the care system, allowing tailor behaviors and promote greater resolution in the treatment of people with venous ulcers in health services of high complexity

Trauma em idosos atendidos pelo serviço pré-hospitalar móvel

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

Autoestima e qualidade de vida de pessoas com úlcera venosa atendidas na atenção primária

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Análise da adesão ao tratamento e da qualidade de vida de pessoas com úlcera venosa

The therapeutic adherence is still a big problem among people with venous ulcers (VU) because the treatment is long, expensive and demand changes in lifestyle. In this context, this study aims to examine treatment adherence and quality of life (QOL) of people with VU assisted at primary health care. This is an analytical, cross-sectional study with a quantitative approach to treatment and data analysis. The study had the scenario 13 Family Health Units and 02 Units Mixed of Natal. The target population consisted of 44 persons with UV indicated by the teams of the Family Health Strategy between February and April 2014. Three instruments were used: an instrument to characterize the sociodemographic, health and care aspects, the Multidimensional Scale of Adherence Therapy composed of the dimensions: healthy lifestyle, compressive therapy and neurovascular monitoring and the Charing Cross Venous Ulcer Questionnaire (CCVUQ) that evaluates QOL in persons with VU composed by the domains: Total Score, Social Interaction, Domestic Activities, Aesthetics and Emotional State. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, CAAE: 07556312.0.0000.5537. The data concerning the sociodemographic characteristics showed that there was a predominance of females (65.9%), age range as of 60 years (59.1%) and income of up to 1 minimum wage (81.8%). With the characterization of health, it was evident that most people reported chronic diseases (63.6%), sleep more than 6 hours (81.8%), present pain (81.8%), denying alcoholism (86 4%) and smoking (77.3%) and showed a number greater than or equal to 1 (77.3%) recurrences. Concerning the therapeutic adherence was found that in the dimension compressive therapy there poor adherence. No associations between the domains of adherence and sociodemographic and health variables were found. Was observed, however, better adherence among individuals without pain and with higher schooling. When analyzed the averages of the dimensions of therapeutic adherence with the care characteristics there was statistical significance between: adherence to compression therapy and guidance for use of compressive therapy (p = 0.002) and guidance for regular exercise (p = 0.026). Considering the mean of total score of CCVUQ (mean 51.47, SD 18.33) it is observed that the overall QOL of respondents has approximate value of the median of the scale (50). The mean of the domain Social Interaction (mean 44.23, SD 21.38) and Domestic Activities (mean 45.70, SD 23.21) were those who reported better QOL. There were weak correlations but significant between adherence to healthy lifestyle and Domains Total Score (p = 0.012), social interaction (p-value = 0.048), Aesthetics (p-value = 0.025) and Emotional State (0.017) of CCVUQ. From the data analysis it is concluded that among people with UV, there poor adherence to compressive therapy. Furthermore, we found no statistically significant association between treatment adherence and sociodemographic and health characteristics. It is added that there was a correlation between the healthy lifestyle dimension and domains CCVUQ

Influência do cultivo da cana-de-açúcar e da mineralogia da fração argila nas propriedades físicas de latossolos vermelhos

As atuais técnicas de manejo da cultura da cana-de-açúcar utilizam um vigoroso revolvimento do solo por ocasião do plantio, com o uso de arados, grades pesadas e subsoladores. O objetivo deste trabalho foi avaliar o grau de modificação de algumas propriedades físicas de um Latossolo Vermelho caulinítico (LVd) e de um Latossolo Vermelho caulinítico-oxídico (LVdf) cultivados com cana-de-açúcar e sob mata nativa no município de Jaboticabal (SP), além de comparar as propriedades físicas encontradas em ambos os Latossolos. O delineamento experimental utilizado foi o inteiramente casualizado, em esquema de parcelas subdivididas 4 x 3 (manejos e camadas), com quatro repetições. Também foi realizada a análise conjunta entre as propriedades físicas dos Latossolos. Os sistemas de uso foram: cana planta (CP), cana soca de segundo ano (C2), cana soca de quarto ano (C4) e mata nativa (MN). Avaliaram-se a densidade do solo (Ds), a sua porosidade e o diâmetro médio ponderado (DMP) nas camadas de 00,10, 0,10-0,20 e 0,20-0,30 m. Os efeitos dos sistemas de uso e manejo sobre os atributos físicos, nas diferentes camadas, foram verificados a partir da análise de variância; quando significativas, as médias foram comparadas pelo teste de Tukey a 5 %. A MN do LVdf apresentou maior macroporosidade e menor microporosidade em relação à das áreas cultivadas, mas, para porosidade total e Ds, a MN apresentou diferença apenas para C2 e C4. O tempo de cultivo da cana-de-açúcar proporcionou o aumento da Ds e diminuição da macroporosidade em ambos os Latossolos. Entretanto, o maior teor de óxido de Fe no LVdf proporcionou maior porosidade total e menor Ds, e sua macroporosidade permaneceu acima de 0,10 m³ m-3 em todos os manejos e camadas. Os sistemas de uso do solo com cana-de-açúcar reduziram a estabilidade de agregados, em relação à mata nativa.

Uso de diferentes formas físicas e quantidades de ração pré-inicial para frangos de corte

The objective of this work was to evaluate the effect of the physical form and quantity of pre-starter diet on the broiler chicks performance. In the first trial, 684 day old males were distributed in a randomized design of three treatments with six replicates of 38 birds. The physical forms of pre-starter diets tested were: mash diet; crumb diet and pellet diet. Another was conducted with 912 day old male distributed in a randomized design of three treatments with eight replicates of 38 birds. The treatments consisted in feeding the broiler chickens with 150 g/bird; 200 g/bird and 250 g/bird. After that, all the birds were fed with the same feed program. In the first week and at 21 days old the birds fed with mash pre-starter diet had body weight gain lower than those fed crumbed and pelleted diets. The variables studied were not affected by the quantity of diets. In conclusion, the physical form of pre-starter diet was important for initial performance and the quantity of pre-starter tip to 150 g/bird did not improve the development of broiler chicks.

Oportunidades de melhoria ergonômica das exigências físicas da atividade jangadeira em Ponta Negra Natal-RN

The fishing is an activity with rafts marked by unpredictability, poor tools, physical stress, awkward postures, risk of accidents and incidents, which contribute to insecurity in the context of activity. This study aimed to contribute to reducing of physical effort and the biomechanical impacts in jangadeiro activity of artisanal fishing using jangadas on the beach of Ponta Negra, Natal-RN. To achieve this purpose the methodology of the Work Ergonomic Analysis - WEA became a reference using techniques such as observational and interactional observation notes, photographs, videos, action conversational and listening verbalizations. The resulting activity in health jangadeiro, discussed in this research were: static postural assessment, flexibility of movement of shoulder flexion-extension, flexibility of the hamstrings and lower back, grip and musculoskeletal pain. It was found from observations, interactions and activity analysis, that in carrying out fishing rafts are frequent awkward postures associated with demand for power and many are already feeling the jangadeiros reflections of years of life dedicated to this work. These have already adopted some measures to manage the activity, such as job rotation during the expedition of capture. Therefore, there is a need to expand these measures of activity management, as well as design and capabilities of the raft, seeking positive changes in the activity and consequently the quality of life jangadeiro

Abordagem da ergonomia para análise da acessibilidade a hóspedes com deficiência visual em hotéis: soluções de inclusão de pessoas cegas e com baixa visão

This study evaluates the level of accessibility for people with visual impairment (blindness and low vision) hotels in the city of Natal-RN, Brazil, and provides principles, guidelines and means of projective make hotels accessible, to promote comfort, autonomy and security of these people. We used a qualitative research methodology and quantitative trait descriptive, analytical and interpretive. Was taken as a base for field studies Ergonomic Analysis of Work, beginning with a study of the demands of accessibility of hotels and analyzing the modeling activity in these establishments through the application of interactional and observational techniques, such as film, photographic records, conversational actions and observation protocols. A protocol was developed and applied to evaluate the compliance of accessibility of hotels in the face of Brazilian technical standard NBR 9050 (2004). We used methods of Cognitive Task Analysis (CTA) associated with simulated activities to identify the processes of decision making and analyzing the observables of the activities performed by people with visual impairment (POS). Interviews were conducted with people who are blind and low vision in various cities in order to meet accessibility difficulties they faced in hotels and recommendations for improvement that they indicate. The mapping results showed that of 16 hotels 4 and 5 star studied in Natal-RN, reached only 7% of the 50 items of the protocol, while none of them reached 70% of the items. About the results obtained in simulated activities and analyzed from the ATC, we saw that the hotel where it was performed this step shows a need to adequately address the guests with visual impairments

Desempenho, eficiência de utilização dos nutrientes e estrutura do trato digestório de pintos de corte alimentados na fase pré-inicial com rações de diferentes formas físicas

Este estudo foi realizado com o objetivo de avaliar o efeito da forma física da ração sobre o desempenho, a utilização dos nutrientes das rações e o desenvolvimento do trato disgestório de pintos de corte na primeira semana de vida. Foram utilizados 150 pintos machos Cobb distribuídos ao acaso em três tratamentos com cinco repetições de dez aves. Os tratamentos consistiram das formas físicas farelada, triturada e peletizada de uma ração pré-inicial comercial. Com exceção da moela, os órgãos do trato digestório e a estrutura morfométrica do intestino não foram influenciados pela forma física da ração. Maior digestibilidade do N foi obtida com a ração peletizada, enquanto a ração triturada possibilitou maior digestibilidade do EE. A energia metabolizável determinada para a ração farelada foi menor que a obtida nas demais formas físicas da ração. As aves alimentadas com ração farelada tiveram menor consumo de ração e ganho de peso e pior conversão alimentar. Ingeriram ainda menos energia, apresentaram menores retenções de proteína, gordura e energia corporal e utilizaram maior proporção da energia ingerida para produção de calor. As rações pré-iniciais na forma peletizada ou triturada possibilitam maior aproveitamento dos nutrientes da ração pelos pintos e melhor desempenho.
