37. Reduced protective effect of Plasmodium berghei immunization by concurrent Schistosoma mansoni infection
Studies on concomitant schistosomiasis and human and experimental malaria have shown a variation in the immunospecific response, as well as an increase in the severity of both parasitoses. In the present study, a murine co-infection model was used to determine the effects of a co-infection with Schistosoma mansoni and Plasmodium berghei on the protective imm

38. Performance prediction and validation of equilibrium modeling for gasification of cashew nut shell char
Cashew nut shell, a waste product obtained during deshelling of cashew kernels, had in the past been deemed unfit as a fuel for gasification owing to its high occluded oil content. The oil, a source of natural phenol, oozes upon gasification, thereby clogging the gasifier throat, downstream equipment and associated utilities with oil, resulting in ineffectiv

39. Growth hormone-insuline-like growth factor-I system in pejerrey Odontesthes bonariensis (Atheriniformes)
Using biotechnology to increase the growth rates of fish is likely to reduce production costs per unit of food. Among vertebrates, fish appear to occupy a unique position, when growth patterns are considered. With few exceptions, fish species tend to grow indeterminately, implying that size is never fixed. Both hyperplasia and hypertrophy contribute to post-

40. Abridged acid-base wet-milling synthesis of high purity hydroyapatite
There is a plethora of routes to produce hydroxyapatite(HA) and in general calcium phosphates(CP) but production usually leads to a mixture of several phases. Besides ionic contamination, most of these methods are cumbersome, restricted to small volumes of product and require a lot of thermal energy. The acid-base route eliminates foreign ions or additives a

42. A influência do porte no desempenho logístico das empresas usuárias do drawback
The use of government duty assistance, like drawback, can be, at first time, always be advantage without considering the firm size. However, many different factors inside and outside of the organization interfere on its use. With the proposal of analyse the influence of the company size on the performance of logistic integrations management activities on the

43. PCR-mediated recombination in development of microsatellite markers: mechanism and implications
Protocols for microsatellite-enrichment libraries have been widely applied to several species in order to supply the most informative molecular markers for population and inbreeding studies. One drawback of these protocols is the ratio of designed primer pairs that fail to amplify the expected fragment, even after exhaustive optimization attempts. A possible

44. Realce de contraste em imagens digitais usando equalização de histograma
Nowadays devices are able to capture and process images from complex surveillance monitoring systems or from simple mobile phones. In certain applications, the time necessary to process the image is not as important as the quality of the processed images (e.g., medical imaging), but in other cases the quality can be sacrificed in favour of time.This thesis f

45. Fontes de erro em medidas eletrogoniométricas de movimentos do joelho
Flexible goniometers are useful for direct movement measurements. However issues related to subject-sensor interface can introduce measurement errors. Crosstalk, i.e. the phenomenon that flexion/extension angles affect the varus/valgus angles, and vice versa, is considered as the main drawback of goniometers. It is not well known the effect of the variation

46. Molecular modeling of arylpiperazine compounds and their interactions with the 5-HT1A receptor / Modelagem molecular de compostos arilpiperazínicos e suas interações com o receptor 5-HT1A
Selective serotonin reuptake inhibitors (SSRIs) are the most important class of antidepressants in current clinical use. However, they present the serious drawback of a delay of two to six weeks in the onset of therapeutic effect. Clinical studies have shown that when a 5-HT1A receptor antagonist is administrated along with a SSRI, an increase of extracellul

47. Avaliação sócio-ambiental do uso de efluente de esgoto tratado na irrigação de culturas no Município de Lins - SP / Socioenvironmental assessment of the use of treated sewage effluent in the irrigation of crops in Lins - SP
Worldwide, there is an increasing competition for the use of water between different sectors of society. The agriculture is a major consumer of the total fresh water available. In this context, it is desirable a reallocation of water resources used in agriculture to other sectors, such as public supply. Since done in a controlled way, irrigation with effluen

48. Retroperitoneoscopic renal biopsy in children
OBJECTIVE: We present our experience in a series of 17 consecutive pediatric patients submitted to retroperitoneal laparoscopic renal biopsy. MATERIALS AND METHODS: Retroperitoneal laparoscopic renal biopsy (LRB) was performed in 5 boys and 12 girls. Mean age was 8.1 years and age range from 2 to 12. Two or three trocars were used to expose the inferior pole
