Desenvolvimento e nutrição do capim-Tanzânia em função da aplicação de zinco

It was aimed to assess the effects of zinc in the development and nutrition of Tanzania grass. The experimental design used was fully randomized, consisting of six doses of zinc (0, 15, 30, 60, 120 and 240 mg dm'3) and four repetitions. The experimental unit was formed in a vase filled with a Red Latosol dystrophic (Zn = 0.4 mg dm). There were two cuts, the first after 53 days of transplanting seedlings and the second 35 days after the first cut. Was evaluated the concentration of zinc in the soil, the content of zinc leaf, the number of tillers, number of leaves, plant height, the dry mass of the shoot, root system and the whole plant. The doses of zinc influenced the concentration of zinc in soil and plant, and production of dry mass of Tanzania grass, especially the first cut. The Tanzania grass shows high tolerance to the toxicity of zinc, and toxic critical level of 273 mg kg-1.

A participação escolar de alunos com deficiência na percepção de seus

The identification of the level of school participation of disabled students is crucial for monitoring the inclusive educational process. It requires the use of measuring instruments that provide functionality before school specific demands, and that at the same time can motivate the teacher to reflect on his judgment about the performance of students with disabilities. School Function Assessment (SFA) is a tool that helps recognize the special needs of students with disabilities according to parameters of functionality and participation. Thus, this study analyzed the influence of the use of SFA on the teacher's judgment of student participation and performance. Eight teachers responded regarding the participation of nine students with disabilities through the use of the SFA and a questionnaire. The results indicated that, for five teachers, SFA helped with the perception of the student's participation, focusing on the activity demand and brought reflections on: the need of evaluation not just in the classroom, co-relation between the degree of disability and the participation of the student, understanding of the specificities of the performance, importance of the adaptation to neutralize incapacity and the importance of the focus deviation from the disability toward functionality.

Descrição do conceito de deficiência a partir da mídia cinematográfica: uma análise comportamental

This work pointed out forming elements from the conception of special necessities that the media show the audience by the movies. An expression description has established special needs and they were identified as keywords on a search of movies (1994-2004) which were analyzed by two observers, according to a script. The results showed that 33 of the movies selected, 39.9% were classified in the ramacategory; 64% shows the disability as organic nature and 57% with predominant clinic diagnoses. Many labeled practices were identified (85%) and few accessibilities options (76%). In 85% of the movies the disability is said a manifestation of problems with few (58%) professionals intervention. The results are discussed by the media role on the concept formation of disabilities, offering interaction models with important role on social practice specification or unsuitable to the relation with the diversity and to the culture.

Úlcera de cameron como causa incomum de anemia por deficiência de ferro

Cameron ulcers are chronic linear lesions willing on the mucosal folds, the level of diaphragmatic impression, in patients with hiatal hernia. Its clinical relevance is due to the potential risk of gastrointestinal complications, such as acute or chronic bleeding and anemia. Usually, the diagnosis is incidental by upper gastrointestinal endoscopy. Proton pump inhibitors are essential for the conduct of cases and the administration of iron when the anemia is associated. Already, the benefit of surgery is in refractory cases. We present a case of this entity of a 50-year-old patient in postmenopausal who developed anemia due to iron deficiency and normal initial endoscopy.

Aspectos relacionais, familiares e sociais da relação pai-filho com deficiência física

The survey sought information from the relationship between father and child with disability regarding space, responsibilities and feelings in the parental relationship. Ten fathers, aged 31 to 66 years, with varied educational and professional backgrounds, answered a questionnaire with 19 semi-structured questions grouped into 16 categories of analysis. The conclusion showed that fathers perceive disability differently over time. The information usually comes from a doctor, but when the disability is not very evident, and doesn't cause significant impairment, realization comes over time. The shock of the discovery and behaviors of rejection are major feelings for fathers. Most fathers report differences in roles played by women and men in raising children; they believe that their responsibility is to provide for the family, while the mother's duty is to accompany the child. They feel that they share with the mothers the responsibility for caring for the child and, in general they don't feel they have been accused of being distant. They try to follow the child's treatment. The children are as attached to them as to other family members. To live with a minimum of quality of life they agreed unanimously about the need for greater income and benefits from social welfare. Most recognize that they are afraid of having other children with disabilities. They express low expectations for the total independence of the children, and among the fathers who have more than one child, the majority acknowledged the existence of differential treatment. They attributed the causes to medical errors. Fathers feel much the same as mothers, but they have different ways of demonstrating what they feel.

Marginal resection for treatment of mandibular osteomyelitis associated with osteopetrosis: Case report

Osteopetrosis (OP) is a rare hereditary disorder characterized by a dysfunction of the osteoclasts that impairs bone resorption, which together with the normal osteoblastic activity forms intense bone sclerosis with reduction of marrow. A common complication that arises, most frequently, as a result of tooth extraction is mandibular osteomyelitis. There is no consensus on the literature about the treatment of this infection in an osteopetrotic patient, therefore, the purpose of this paper is to report a case of marginal resection for treatment of mandibular osteomyelitis in an osteopetrotic patient and discuss relevant features of this procedure. © 2010 European Association for Cranio-Maxillo-Facial Surgery.

Alimentação de leitões com dietas contendo soro de leite fermentado mais zinco e cobre orgânico

An experiment was carried out to evaluate the performance of piglets fed rations containing fermented milk and zinc and copper amino acid complex. Sixty four piglets, littermates, were used. The experimental design was based on random block with two dietary treatments. One of these contained a basal diet (DB) with ZnO e CuSO 4 and the other one with the DB, but without CuSO 4 and with the addition of fermented milk and zinc and copper amino acid complex (SLF Lact +ZnCuAA). There were eight replicate pens per treatment, and pigs were grouped at 4 per pen. The SLF Lact + ZnCuAA didn't not affect (p>0.05) final live weight of the piglets. However, live weight was different (p<0.01) between males and females (24.3 vs. 24.0 kg) at end of experiment. The feed intake of animals feed with SLF Lact+ZnCuAA was higher (p<0.01) in 8% in the first 14 days (0.261 vs. 0.239 kg/d), 15% from 15 to 28 days (0.756 vs. 0.675 kg/ d) and 12% from 29 to 42 days (1.091 vs. 0.962 kg/ d) compared to control group. Daily average feed intake in the experimental period was 11% higher (p<0.01) for the animals fed with the diet contained SLF Lact+ZnCuAA. Weight gain of the treatment with SLFL act+ZnCuAA was higher (p<0.01) by 14% from 0 to 14 days (0.176 vs. 0.152 kg/d), 11% from 15 to 28 days (0.564 vs. 0.500 kg/d) and 12% from 29 to 42 days (0,572 vs. 0,501 kg/d). Average daily weight gain of 42 days of trial of treatment with SLF Lact +ZnCuAA was 12% higher (p<0.01) compared to control group (0.437 vs. 0.384 kg/d). Feed conversion ratio was 8% lower (p<0.01) for treatment with SLF Lact+ZnCuAA in the first 14 days (1.487 vs. 1.614). Supplementation with fermented milk and zinc and copper amino acid complex in diets containing zinc oxide improved growth performance of weanling piglets.

Doses de zinco e nitrogênio na produtividade e qualidade de grãos de ervilha

Peas present a potential to be cultivated in the winter, in Brazil, and also a great importance, especially in human feeding, due to its high protein content. However, its yield is still low and there are just a few studies aiming at improving pea grains quality and yield. This study aimed at evaluating the nitrogen and zinc fertilization effect on the pea grains (Utrillo cultivar) chemical quality and yield. The experiment was carried out in a dystrophic clayey Latosol-Haplustox, in Selvíria, Mato Grosso do Sul State, Brazil, in 2005. A randomized blocks design was used, in a 4×4 factorial scheme, totaling 16 treatments and 3 replications, including four nitrogen doses (0 kg ha-1, 60 kg ha-1, 120 kg ha-1, and 240 kg ha-1), as urea, via ground, at 30 days after sowing (DAS), and four zinc doses (0 kg ha-1, 1,5 kg ha-1, 3 kg ha-1, and 6 kg ha-1), as zinc sulphate, via leaf, at 45 DAS. The combination of zinc and nitrogen doses improved the grains chemical quality. Zinc had no effect on grain yield, however, high nitrogen doses negatively affected yield.

Influence of buccal bony crest width on marginal dimensions of peri-implant hard and soft tissues after implant installation. An experimental study in dogs

Aim: To evaluate the influence of the width of the buccal bony wall on hard and soft tissue dimensions following implant installation. Material and methods: Mandibular premolars and first molars of six Labrador dogs were extracted bilaterally. After 3 months of healing, two recipient sites, one on each side of the mandible, were prepared in such a way as to obtain a buccal bony ridge width of about 2 mm in the right (control) and 1 mm in the left sides (test), respectively. Implants were installed with the coronal margin flush with the buccal alveolar bony crest. Abutments were placed and the flaps were sutured to allow a non-submerged healing. After 3 months, the animals were euthanized and ground sections obtained. Results: All implants were completely osseointegrated. In respect to the coronal rough margin of the implant, the most coronal bone-to-implant contact was apically located 1.04 ± 0.91 and 0.94 ± 0.87 mm at the test and control sites, respectively, whereas the top of the bony crest was located 0.30 ± 0.40 mm at the test and 0.57 ± 0.49 mm at the control sites. No statistically significant differences were found. A larger horizontal bone resorption, however, evaluated 1 mm apically to the rough margin, was found at the control (1.1 ± 0.7 mm) compared to the test (0.3 ± 0.3 mm) sites, the difference being statistically significant. A thin peri-implant mucosa (2.4-2.6 mm) was found at implant installation while, after 3 months of healing, a biological width of 3.90-4.40 mm was observed with no statistically significant differences between control and test sites. Conclusions: A width of the buccal bony wall of 1or 2 mm at implant sites yielded similar results after 3 months of healing in relation of hard tissue and soft tissues dimensions after implant installation. © 2012 John Wiley & Sons A/S.

Softwares educativos para alunos com deficiência intelectual: Estratégias utilizadas

The computer is present in everyday school life and using it with educational software must be mediated and planned in order for this resource to contribute to student learning, including those with intellectual disabilities (ID). Therefore, the aim was to propose specific computer activities for students with ID using educational software, and to quantify and analyze the technical and pedagogical strategies used. The participants were six students with ID enrolled in two public schools. To collect information we used observation protocols and a field journal. Data were analyzed quantitatively and qualitatively, based on the concepts of mediation and the zone of proximal development of cultural-historical theory. The results indicated that when the content developed in the computer classes were compatible with the proposed activities in the classroom, students with ID had opportunities to experience different activities that enable them to be successful. We noted that what enabled them to understand and correctly perform the proposed activities were the teaching strategies. Thus, we consider that technical knowledge about educational software and pedagogical knowledge about content that is being worked on, are insufficient to ensure that the proposed activity will contribute to the development of students with ID.
