O Evangelho segundo a Pastoral da Criança :por uma pedagogia da sobrevivência

This work aims to analyze social and educational actions at Pastoral da Criança, using education as a survival tool. This was done at Parque dos Coqueiros, a neighborhood in Natal, Rio Grande do Norte. The methodology for data collection was composed of comprehensive interview (Jean Kaufmann), participant observation (Robert Bogdan) and documental analysis (Le Goff); all os which bring reflections related to concepts such as strategies, tatics and know how (Michel de Certeau), configuration (Nobert Elias), and control technology (Michel de Foucault), care ethics (Leonardo Boff) and etno-theories (Natália Ramos). Pastoral da Criança is a social action organism that belongs to the National Conference of Bishops of Brazil, originated at Florestópolis, Londrina (Paraná), in the year of 1983. These actions have been an expression of a new logic of actions of the Catholic Church. It values the participation of laymen in the activities of the Pastoral. Thus, the parish is seen as a nucleus that irradiates the Church s Social Doctrine. At Rio Grande do Norte this institution has guided poverty stricken families on issues related to children s health as well as working with laymen for volunteer work. This is considered devotion, that is firmed by an individual and group mystique. The social and educational actions are done in three axes: 1) Monthly home visits, where there is mother-child support; 2) Life Celebration Day, where they weigh children and promote nutritional surveillance; 3) Meeting for Evaluation and Reflection, that aims to articulate community leaders to think about problems attached to the social actions they realize. This action tripod , as it is called by the Pastoral Agents are the types of actions that fundament survival education for poor children ranging from 0 to 6 years old. The families learn to deal with prevention, the essential, the alternative and probabilities of survival tactics due to exclusion matters or even social extermination. The Pastoral da Criança aims to recover childhood emotions in poverty stricken areas. It also has influence in the diminishing of malnutrition and mother and child mortality. This education for survival is the base on the art of teaching and learning of poverty stricken children. It is a social educational action, non assistencialist, but considered a shy action in order to promote mobilization of the communities that are accompanied for the emancipation and change of social conditions

Sensitivity evaluation of a single-step PCR assay using Ehrlichia canis p28 gene as a target and its application in diagnosis of canine ehrlichiosis

O objetivo deste estudo foi aperfeiçoar um ensaio de PCR que amplificasse um fragmento de 843 pares de bases do gene p28 da Ehrlichia canis e compará-lo com outros dois métodos de PCR utilizados para amplificar partes do gene 16S rRNA e dsb do gênero Ehrlichia. Amostras sanguíneas foram colhidas de cães com diagnóstico clínico de erliquiose. A amplificação do gene p28 pela PCR produziu um fragmento de 843pb e esse ensaio permitiu a detecção do DNA de um parasita dentre 1 bilhão de células. Todas as amostras positivas detectadas pela PCR baseada no gene p28 foram também positivas pela nested PCR para detecção do gene 16S rRNA e também pela PCR dsb. Dentre as amostras negativas para a PCR p28, 55,3% foram co-negativas, mas 27,6% foram positivas pela PCR baseada nos genes 16S rRNA e dsb. A PCR p28 parece ser um teste útil para detecção molecular de E. canis, entretanto otimizações na sensibilidade nesta PCR são necessárias, para que esta técnica se torne uma importante alternativa no diagnóstico da erliquiose canina.

Infestation of froghopper nymphs changes the amounts of total phenolics in sugarcane

The increased rate of sugarcane harvest without previous burn has provided a very favorable environment to the froghopper Mahanarva fimbriolota (Stal, 1854), with high Moisture and low temperature variation. Few works have Studied the response of sugarcane to this pest, so little is known about resistant cultivars. Plant phenolics are widely studied compounds because of their known antifierbivore effect. This research aims to determine if the attack of M.fimbriolata nymphs stimulates the acccumulation of total phenolics in sugarcane. The experiment was carried Out in greenhouse and arranged in completely randomized design, in a 3 x 2 x 4 factorial with three replications. Second instar nymphs of M. fimbriolota were infested at the following rates: control, 2-4 and 4-8 nymphs per pot (first-second infestations, respectively). Pots were covered with nylon net and monitored daily to isolate the effect of leaf Sucking adults. Leaf and root samples were collected and kept frozen in liquid nitrogen until analyses. Infested plants showed higher levels of phenolics in both root and leaf tissues. In roots, the cultivar SP80-1816 accumulated more phenolic compounds in response to the infestation of M. fimbriolata. on the other hand, higher levels were found in leaves and roots of control plants of SP86-42, which might be an indication of a non-preference mechanism. The increase of total phenolics in sugarcane infested with root-sucking froghopper nymphs does not seem to be useful to detect the resistance to this pest.

Ações de profissionais relativas ao banco de leite humano : uma perspectiva de mudança

This is an exploratory and descriptive study that aimed to investigate the actions of professionals in the context of breastfeeding, on the assumption that the actions taken by employees working together to postpartum and newborn are not competing to effect the distribution of pasteurized human milk so that it meets the needs of infants who depend on it. Thus, the study aimed to analyze the actions of medical and nursing staff of the distribution of pasteurized human milk to the newly born. The investigation was developed by action research in a federal hospital, located in the capital the state of Rio Grande do Norte, Brazil, reference assistance to women during pregnancy, childbirth and postpartum high risk in 2010. Study participants were fifty-five professionals chosen from the following inclusion criteria: to act in the NICU or rooming, being a pediatrician and / or neonatologists, nurses and technical nursing. According to the methodology of action research a questionnaire was applied, techniques in focus groups and courses were developed, and, finally, action evaluation. The project was submitted to the Ethics Committee at the Federal University of Rio Grande do Norte and approved with no protocol 448/2009. The problems identified in the responses issued by the social research were grouped into categories according to the similarity between them. The answer to the question of the survey - How is the need for pasteurized human milk for the newborns in neonatal intensive care unit and rooming identified? - Brought subsidies for action planning and implementation of strategies for change in the practice of professionals working in rooming and ICU. Thus, the study has relevance in social care and, when at the local level, will compete for the distribution pasteurized human milk to take effect as best as possible, as recommended by the Ministry of Health. It is also conceived that, in a macro view of society, it could contribute to minimizing the health problem that involves the child population

Adição de areia para dispersão de solos na análise granulométrica

A acurácia da análise granulométrica depende da obtenção de suspensões de solo completamente dispersas e estáveis para possibilitar a separação das suas frações granulométricas. O objetivo do presente trabalho foi avaliar a eficácia da adição de quantidades e tamanhos de grãos de areia na fase de dispersão da análise granulométrica de solos, visando à maior acurácia na obtenção dos resultados da análise granulométrica. Os solos utilizados foram: Latossolo Vermelho eutroférrico (LVef), LatossoloVermelho acriférrico (LVwf), Latossolo Vermelho eutrófico (LVe), Argissolo Vermelho-Amarelo eutrófico (PVAe) e Nitossolo Vermelho eutroférrico (NVef). A dispersão das amostras dos solos foi realizada por meio da adição de hidróxido de sódio e agitação rotativa (60 rpm) por 16 h. O delineamento experimental adotado foi o inteiramente casualizado, com esquema fatorial 6 x 2, com três repetições. Os tratamentos foram constituídos por seis quantidades (0, 5, 10, 15, 20 e 25 g) e dois diâmetros (2,0-1,0 e 1,0-0,5 mm) de areia, adicionados na fase de dispersão da análise granulométrica dos solos. de acordo com as equações ajustadas, a adição de areia com diâmetro entre 1,0 e 0,5 mm nas quantidades de 21,4 g para LVef, 19,6 g para LVwf e 25,8 g para NVef proporciona, respectivamente para esses solos, aumentos de 50, 38 e 14,5 % nos teores de argila. No LVe e no PVAe não se justifica a adição de areia na análise granulométrica, pois esses solos não apresentaram problemas de dispersão. Os resultados demonstram que a adição de 25 g de areia, com diâmetro entre 1,0 e 0,5 mm, na fase de dispersão da análise granulométrica de solos argilosos com altos teores de óxidos de Fe e com dificuldades de dispersão, é eficiente para promover efetiva dispersão das partículas primárias do solo.

Características de latossolos roxos desenvolvidos de rochas alcalinas e básicas de Jaboticabal, SP

Comparou-se as características químicas, físicas e mineralógicas de Latossolos Roxos desenvolvidos de rocha alcalina (LRe) e de rocha eruptiva básica (LRd), da região de Jaboticabal, SP. Os resultados indicaram que o LRe apresenta-se num estádio de desenvolvimento, comparativamente, menos evoluído que o LRd, enquanto esse se apresenta com tendência para a maturidade. Os menores teores de argila e ferro total e maiores teores de saturação por bases, Ki e CTC da fração argila apresentados pelo LRe comprovam esta tendência. Conclui-se que a ocorrência de Latossolo Roxo eutrófico no campus da UNESP-Jaboticabal, pode estar associada a participação de rochas alcalinas na sua pedogênese.
