Seasonal effects of wastewater to the water quality of the Caeté river estuary, Brazilian Amazon

A situação socioeconômica de Bragança depende principalmente dos recursos biológicos estuarinos e marinhos, que são influenciados pelos ciclos de marés e climatologia. Coletas oceanográficas (com medidas de variáveis hidrológicas, hidro-dinâmicas e microbiológicas) foram realizadas na área mais urbanizada do estuário do Caeté, para caracterizar a qualidade das águas no setor estudado. Durante o período seco, o estuário foi mais eutrófico e apresentou os maiores valores de temperatura (30,5°C em Out./06), salinidade (17 psu em Fev./07), pH (8,24 em Fev./07) e coliformes fecais (>1000 MNP/ 100 ml em Dez./06 e Fev./07). As espécies fitoplanctô-nicas Cyclotella meneghiniana, Coscinodiscus centralis e outras espécies r-estrategistas também foram observadas. A falta de saneamento básico foi responsável pela contaminação local, especialmente durante o período seco, quando o esgoto foi lançado mais concentrado no estuário, mostrando a influência humana na redução da qualidade da água estuarina estudada. A pesca é considerada uma das principais atividades econômicas do município de Bragança e, portanto, esta contaminação poderá afetar negativamente a qualidade ambiental deste ecossistema amazônico.

Ocorrência de contusões em carcaças bovinas em frigorífico

The animal welfare is a series of practices that involves the maintenance of psychological and physiological freedoms of animals, to them remain healthy until slaughter and provide a satisfactory quality carcass and to avoid unnecessary suffering to animals. One way to evaluate the animal welfare is monitoring the occurrence of bruises on carcasses that is an indicative of inadequate management of the animals. The present study aimed to evaluate the occurrence of bruises in cattle carcasses at a slaughterhouse located in the Midwest Region of the State of São Paulo, Brazil. Was applied a check-list that determined the presence of bruises, the location and severity of them, ranking among scores I to III. Was observed in 98% (880/898) of the animals the presence of contusion. The Grade I injuries in the region of the hips at half carcasses had higher incidence with an average of 61.8% between the right and left sides. Could be observed multiple lesions in several animals slaughtered. In 133 animals observed were removed 15.6 kilograms of material only the injured region only of the hips, demonstrating economic losses to cattle farmers and industries for failures in animal welfare practices. The inappropriate pre-slaughter management compromises animal welfare and the quality of carcasses, discrediting our products on international meat trade and consisting in economic losses to the national cattle herds.

Influence of Parity and Season of the Year on Oocyte Quality and Number in Buffaloes

The aim of the present study was to evaluate the effects of season of the year (summer and winter) and parity (heifers and cows) on oocyte quality and number in buffaloes. For this purpose, 71 buffaloes had follicular wave emergence synchronized before OPU. OPU of all follicles >= 2mm was done 5 days after the beginning of the hormonal protocol, in 4 replicates (two for each season). Data were analyzed by ANOVA using PROC GLIMMIX, in a 2 x 2 factorial arrangement of treatments. No interactions were observed in following variables: number of follicles, number of total and viable oocytes, recovery rate, percentage of viable oocytes, grade I oocytes, grade II oocytes, grade III oocytes, denuded oocytes, expanded cumulus oocytes, and atretic/degenerated oocytes. Number of follicles visualized at OPU and recovery rate were not affected by parity or season. Relative to parity, number of total and viable oocytes were greater in heifers than in cows, respectively. Concerning season of the year, number of viable oocytes and viable oocyte rate were increased in winter. In conclusion, better oocyte quality can be obtained from heifers and during winter in buffaloes. However, the number of total oocytes seems to be more influenced by parity than by season of the year in this species.

O provimento do cargo do gestor escolar e a qualidade de ensino nas escolas públicas: análise a partir das publicações nacionais (1990-2005)

The research that originated this article was aimed at analyzing how the Brazilian publications from 1990 through 2005 set out the relationship between the appointment of school principals and democratic management and quality education. To that end, 38 books were selected and divided into three periods: 1990-1995; 1996-2000; 2001-2005. The findings indicate that from the second period on there is increasing consensus among scholars about the election of school principals as a form of appointment directly related to the democratization of management and quality improvement, defined as a collective and participatory construction of educational goals and practices.

Calvarial Autogenous Bone Graft for Maxillary Ridge and Sinus Reconstruction for Rehabilitation With Dental Implants

Autogenous bone grafting is the gold-standard technique for bone augmentation procedures prior to implant placement. If the amount of available intraoral donor bone is insufficient, it is necessary to harvest bone graft from extraoral sites, such as calvaria. Although this technique is well established, only a few case reports show the histological analysis of the grafted bone at the moment of implant placement. This article reports the case of a 48-year-old female patient with a critical atrophic maxillary ridge reconstructed using autogenous calvarial bone graft prior to implant placement, with clinical and histological evaluation. Bone was collected under general anesthesia from the parietal bone. The outer cortical originated the bone blocks, and the medullar bone layer between was collected to be used in the sinus augmentation procedure, together with 5 of the bone blocks triturated. Six months after bone augmentation, 8 implants were placed in the grafted area and 2 biopsies were retrieved (anterior and the posterior regions), allowing the visualization of the bone-remodeling process in the grafted areas. The patient had a stable recovery. Our results showed that although necrotic bone could still be seen in the outer layer of the grafted area, the interface between this necrotic bone and the already remodeled bone was consistent with biocompatibility. Two-year radiographic evaluation showed success of the grafts and the implants in supporting an esthetic and functionally stable prosthesis. Summarizing, calvarial bone grafts are a viable alternative for the attainment of adequate bone volume prior to implant placement.

Relação entre potenciais evocados auditivos de média latência e distúrbio de processamento auditivo: estudo de casos

The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.

Resistência à tração de coroas de NiCr cimentadas sobre munhões de liga de titânio, com 4 diferentes tipos de cimentos

In this work of tensile strength was evaluated the efficacy of 4 cements (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelyX Luting 2 composite resin/glass ionomer and Panavia 21 TC special acrylic resin) used to fix NiCr crowns to usinated titanium alloy abutments. Were used 40 abutments distributed in groups of 10 elements, to each material. The mechanical essays were developed at a MTS 810 universal machine, adjusted to a 0.5 mm/m velocity. The ANOVA applied to data pointed out the existence of significant differences between groups; the subsequent Tukey´s test (p<0.05) also detected significant differences, except at comparisons of phosphate versus RelyX and phosphate versus Ketac Cem. The better performance was presented by Panavia 21 (1,127.996 N); RelyX (478.197 N) showed itself similar only to phosphate (430.662 N), wich had a performance similar to that of Ketac Cem (227.705 N).

Considerações sobre a não-realização da vogal epentética em corpus poético do Português Arcaico

This study has as main aim to discuss the motivation for the non-occurrence of epenthetic vowel at the beginning of the word in the context of word junction in the first hundred Cantigas de Santa Maria (CSM – Afonso X, 1221-1284). Through this work and from a non-explored corpus (especially as for linguistic themes - SNOW, 1987, p. 478-480; MASSINI-CAGLIARI, 2005, p. 24-26), we intended to contribute to reaching a deeper knowledge of Portuguese prosody history in the period of its recognition as an “independent” language in relation to Latin.
