Encampment time : an anthropological analysis of the land occupations in Brazil

In this article the social trajectory of a land occupation participant, an encamped woman (Edesmaria) who is a member of an extended landless family, is closely examined in order to demonstrate the inner workings of what is called 'the world of land occupations' in Brazil. Through a native expression (encampment time), it is demonstrated that nowadays, for some individuals, involvement in land occupations and landless workers' movements represents not just an opportunity to claim a parcel of land, but, even more importantly, a chance for social mobility and recognition. In this sense, encampment time is a social code and, as such, it not only quantifies the amount of time spent in a given encampment, but it is also a marker of prestige and status as well as a principle that organises and orders social relations in the land occupation world.

Collaboration of ultrasonography in the diagnosis of thyroid gland carcinoma in a dog - case report

The sonographic evaluation of thyroid glands in veterinary medicine presents challenges due to the complexity of the anatomical region, professional experience and type of ultrasonography equipment. The technique is considered a versatile diagnostic method that is noninvasive and has a low cost indicated in different clinical situations. Thyroid carcinoma is a malignant tumor that is often invasive and frequently metastatic to regional lymph nodes and lungs. The prognostic indicators for survival after surgery include tumor size, histological type, mobility and presence or absence of metastasis. The objective of the present report is to demonstrate the importance of ultrasound as a complementary method in the evaluation of thyroid carcinoma in dogs. At the Dr. Halim Atique Veterinary Hospital, an eight-year-old male Pit Bull was examined due to a history of firm painless swelling, approximately six inches in diameter, in the ventral cervical region, for about two months. The sonogram showed a nodular area, with defined and regular margins, and heterogeneous hypoechoic parenchyma, with areas of cavitation and swelling of the thyroid. Histopathology of the nodule was consistent with carcinoma. After thyreoidectomy and hormone replacemet, the patient is in good clinical condition.

Avaliação do efeito tóxico do herbicida trifluralina por meio do estudo histológico e histoquímico do intestino médio do diplópodo Rhinocricus padbergi

Currently the use of pesticides in agriculture is widespread due to their high effectiveness in combating pests, weeds and diseases leading to better productivity and economical performance in agricultural area. The use of pesticides affects the whole world and their use is often performed in an improper and indiscriminate way and for long periods. Several studies have been carried out in order to verify the presence of pesticides in nature, with worrying results. The presence of higher levels of pesticides and their degradation products in soil and surface and groundwater have indicated increasing contamination. Among the most widely used pesticides, herbicides are present and among these trifluralin has occupied an important place due to its widespread use; it is an herbicide originated from benzene derivatives belonging to dinitroanilines family; it is classified as belonging to group C, being possibly carcinogenic for humans, present a high persistence in soil as a result of its low mobility and therefore may affect local edaphic fauna. Diplopods belong to a group of invertebrates considered important in the soil dynamics; due to their close contact with it, these animals can be used as bioindicators of substrates toxicity. This study aimed to expose diplopod specimens of the species R. padbergi to different concentrations of trifluralin and therefore it was mounted five bioassays containing soil from the site where animals were collected (control group) and the same soil mixed to different concentrations of trifluralin herbicide (concentration recommended for agriculture use, that is, the dose recommended by the producer 0.0534g/m2, double, haft and quarter of this dose), animals were exposed for 7 and 90 days. During the entire period of exposure (90 days), it was observed that the number of animals in the control bioassay remained stable until the 5th week, presenting only...

Sociedade, tecnologias e educação: as tecnologias da informação e comunicação e o pensar da sociedade concreta

The information society is increasingly incorporating the immense volume of content available on the net. Access by electronic devices and the resulting ease of mobility and portability feed discussions on actual capacity of appropriation of this knowledge that circulates through cyberspace. Address and discuss the possibilities of educating across the network, therefore, gains more and more importance. On models of educational quality well developed – as is the case in Finland, for example-, Brazilian education is, year after year, failing in international marathons to achieve below average indexes required. Creates a field of analysis, in which this article arises, in the quest to understand more deeply the opportunity of use of Information and communication technologies (ICT) for a quality education, plunging by cultural issues that fall in the construction of objective conditions offered to students. This is an effort in understanding the historical factors that limit efforts to offering a quality education in Brazil.

Associação da raspagem com antibioticoterapia em um caso de periodontite agressiva generalizada

The treatment of aggressive periodontitis is a challenge to the clinician, therefore the search for effective treatment protocols of this disease is important. The aim of this case report was demonstrate the effectiveness of the combination of systemic antibiotics with non-surgical periodontal therapy in the treatment of generalized aggressive periodontitis. a 27-year-old patient (RCS), smoker for 11 years (10 cigarettes/day on average), with no systemic alteration, attended the periodontal clinic with a complaint abnormal dental position. After the clinical examination, the diagnosis of generalized aggressive periodontitis was defined. The non-surgical periodontal treatment was executed associated with administration of amoxicillin plus metronidazole for ten days. Clinical parameters (Clinical Attachment level, marginal gingival level, periodontal probing depth, bleeding on probing, plaque index and gingival index) and radiographic parameters (distance between the cemento-enamel junction and the bone crest) were evaluated before and after non-surgical periodontal treatment, after antibiotic therapy and three, six and 12 months after the treatment. After one year follow-up, the results showed improvement in clinical and radiographic parameters with stabilized and decreased tooth mobility and absence of tooth loss. It was concluded that the association of non-surgical periodontal therapy with the administration of amoxicillin/metronidazole was effective in the treatment of generalized aggressive periodontitis.

Influence of dental chair backrest inclination on the registration of the mandibular position

Varying the inclination of the dental chair backrest might alter the distribution of occlusal contact points. The purpose of this study was to identify the influence of backrest inclination on the registration of the mandibular position. Ten participants aged between 18 and 30 years with a complete permanent dentition, uncompromised motor function, no tooth mobility, and no temporomandibular disorders were selected. To register interocclusal contacts, an autopolymerizing methylmethacrylate device was adapted to the maxillary anterior teeth and a composite resin increment was added to the mandibular central incisors. Contacts were registered with the following variations in the inclination of the dental chair backrest: 90 degrees, 120 degrees, and 180 degrees. A standardized digital photograph was made of each mark in each backrest position, and the images were superimposed to measure the distances in registration from 90 to 120 and from 90 to 180 degrees. Data were analyzed with the Student paired t test (α=.05). When the chair was inclined from the 90-degree to the 120-degree position, the mandible was repositioned posteriorly by a mean of 0.67 mm, but the difference was not statistically significant. When the chair was inclined from the 90-degree to the 180-degree position, however, the mandible was repositioned posteriorly by a statistically significant mean of 1.41 mm. Mandibular position is influenced by increasing inclination, and this influence was statistically significant at a 180-degree incline.
