1. Transbordamentos: elementos para uma cartografia dos campos cegos nos jogos da arte / Overflows: elements for a mapping of the blind fields in art sets
O trabalho explora a dinâmica dos jogos plásticos nas artes e das operações de suas obras enquanto máquinas de visão, dispositivos através dos quais determinados aprendizados se desenvolvem enquanto promovem certos processos de invisibilização. Entre negociações dos modos de ver se instaura a instituição do estatuto coletivo do visível. Fatores

2. \"Cego é aquele que só vê a bola\". O futebol em São Paulo e a formação das principais equipes paulistanas: S.C. Corinthians Paulista, S. E. Palmeiras e São Paulo F.C. (1894-1942) / \"Blind is the one who only sees the ball\". Football in São Paulo and the formation of the major teams from São Paulo: S. C. Corinthians Paulista, S. E. Palmeiras and São Paulo F. C. (1894-1942)
In recent years, many studies on the practice of football in Brazil have been carried out in different areas of knowledge. Understood as a broad-ranging social phenomenon, football which was once despised by intellectuals and academia has become a privileged source for the study of many interconnected social phenomena. Despite the development of said studies

3. CD34 immunoexpression in penile carcinoma
OBJECTIVE: To investigate microvessel density as a risk factor in squamous cell carcinoma of the penis. METHODS: Fifty patients with penile carcinoma were evaluated retrospectively. The mean age and standard deviation were 60.8±11.8 years. All of them were treated by penectomy and with positive nodes underwent groin lymphadenectomy. Tumor grading was 36 G1

4. VEGF immunoexpression in penile carcinoma
OBJECTIVE: To investigate the vessel endothelial growth factor (VEGF) as a risk factor in squamous cell carcinoma of the penis (SCCP). METHODS: Forty-seven patients with penile carcinoma were evaluated retrospectively. The mean age and standard deviation were 61.1±11.7 years. All of them were treated by penectomy and those with positive nodes underwent groi

5. Distribution and aetiology of blindness and visual impairment in mesoendemic onchocercal communities, Kaduna State, Nigeria. Kaduna Collaboration for Research on Onchocerciasis.
During a field trial of ivermectin in Kaduna State, 6831 people age 5 years and above, living in 34 mesoendemic onchocercal communities in Kaduna State, northern Nigeria, were examined for ocular disease. Visual function assessments included tests of visual acuity and visual fields. A total of 185 individuals (2.7%) were bilaterally blind by acuity criteria

6. Lack of effect of weak low frequency electromagnetic fields on chick embryogenesis.
Fertilised chicken eggs were incubated for 48 hours while exposed to pulsed trains of square wave magnetic fields having a duration of 0.5 msec and pulse repetition rates of 100 or 1000 Hz at magnetic field flux densities of 1.2 and 12 mu T. After exposure the embryos were scored blind for eight different gross structural features: primary vesicles, anterior

7. Visual field rehabilitation in the cortically blind?
Investigators have recently reported that specific practice facilitates the restitution of visual fields in partially blinded humans with lesions to the striate cortex. In order to further evaluate this work, attempts were made to retrain twelve homonymous hemianopic or quadrantanopic patients with similar methods, but under conditions in which possible cont

8. Massive cross-modal cortical plasticity and the emergence of a new cortical area in developmentally blind mammals
In the current investigation, the neurophysiological organization of the neocortex was examined in adult animals that were bilaterally enucleated very early in life, before the retino-geniculo-cortical pathway was established. Our results indicate that some aspects of development of cortical fields are not mediated by specific sensory inputs. However, the cu

9. Decomposition of a mixture of signals in a model of the olfactory bulb.
We describe models for the olfactory bulb which perform separation and decomposition of mixed odor inputs from different sources. The odors are unknown to the system; hence this is an analog and extension of the engineering problem of blind separation of signals. The separation process makes use of the different temporal fluctuations of the input odors which

10. Metabolic mapping of the primary visual system of the monkey by means of the autoradiographic [14C]deoxyglucose technique.
An autoradiographic technique that employs 2-[14-C]deoxyglucose to measure the local rates of glucose utilization within the brain has been applied to the binocular visual system of the Macaque monkey. This method, which pictorially displays the relative rates of glucose consumption in the component structures of the brain, delineates the regions of altered

11. Effects of 50 Hz electric currents on vigilance and concentration.
Seventy six male volunteers were studied in a crossover trial to assess the effect on the central nervous system of 50 Hz electric currents. Currents totalling 500 microamperes were passed through electrodes attached to the head, upper arms, and feet, simulating exposure to a vertical electric field of about 36 kV/m. Exposure and sham exposure sessions were

12. The field adaptation of the human rod visual system.
1. Incremental thresholds were measured in a retinal region 12 deg temporal from the fovea with a target of 200 ms in duration and 6 deg in diameter superimposed on background fields of various intensities and wavelengths. Measurements were made under rod-isolation conditions in five normal observers and in a typical, complete achromat observer who had no co
