1. The concurrent accuracy of the modified telephone interview for cognitive status and mini-mental state examination tools in detection of cognitive impairment among older adults
RESUMO. Diante da necessidade de administração face a face de muitos testes de triagem cognitiva, nem sempre é viável rastrear amostras em grande escala. Objetivo: O objetivo deste estudo foi avaliar a validade discriminante da versão persa do Telephone Interview for Cognitive Status (TICS-m) e do Miniexame do Estado Mental (MMSE) na população irani

2. Impairments of facial detection in tobacco use disorder: baseline data and impact of smoking duration
Objective: Chronic tobacco consumption, classified as tobacco use disorder (TUD), has been associated with a variety of health problems. Investigations of face processing in TUD are hampered by lack of evidence. Here, we evaluated facial detection in TUD and assessed test-retest reliability for a facial detection task. Methods: Participants were instructed

3. Monitoring structures with optical fibers: infiltration detection
ABSTRACT The use of sensors and optical fibers for monitoring structures is continuously growing. Strains, displacements, accelerations, temperatures are just a few of the monitoring possibilities. In the case of dam structures, concrete face rockfill dams constitute a type of structures where the monitoring of water infiltrations is of particular interest.

4. Standardization of the face-hand test in a Brazilian multicultural population: prevalence of sensory extinction and implications for neurological diagnosis
OBJECTIVE: The face-hand test is a simple, practical, and rapid test to detect neurological syndromes. However, it has not previously been assessed in a Brazilian sample; therefore, the objective of the present study was to standardize the face-hand test for use in the multi-cultural population of Brazil and identify the sociodemographic factors affecting t

5. Role of a GenoType MTBDRplus line probe assay in early detection of multidrug-resistant tuberculosis at a Brazilian reference center
Resistance to Mycobacterium tuberculosis is a reality worldwide, and its diagnosis continues to be difficult and time consuming. To face this challenge, the World Health Organization has recommended the use of rapid molecular tests. We evaluated the routine use (once a week) of a line probe assay (Genotype MTBDRplus) for early diagnosis of resistance and for

6. Proposing the novelty classifier for face recognition
INTRODUCTION: Face recognition, one of the most explored themes in biometry, is used in a wide range of applications: access control, forensic detection, surveillance and monitoring systems, and robotic and human machine interactions. In this paper, a new classifier is proposed for face recognition: the novelty classifier. METHODS: The performance of a novel

7. Reconhecimento de faces com filtragens de frequências espaciais altas e baixas nos hemicampos visuais direito e esquerdo / Facial recognition in high and low spatial frequency filtering in the right and in the left hemifields
This study aimed to investigate whether face recognition occurs primarily by analytic or holistic processing in the cerebral hemispheres of men and women through the study of the spatial frequency spectrum. Therefore, in Experiment I, 40 volunteers (20 women) performed two sessions. In each of, 14 faces were memorized for a recognition task and each face was

8. Construção de sistemas bacterianos para a detecção de metais pesados em amostras ambientais. / Construction of bacterial systems for the detection of heavy metals in environmental samples.
Aiming at the construction of three bacterial biosensors for metals mercury, arsenic and lead, Cupriavidus metallidurans CH34 was chosen to obtain the DNA fragments (by PCR) corresponding to operons mer, ars and pbr. The fragments were inserted upstream of the EGFP gene, in plasmid pBB-EGFP, getting three new plasmids: pGHg, pGAs and pGPb. They were cloned i

9. Inquérito domiciliar sobre as percepções da população em relação à hanseníase em um município hiperendêmico de Minas Gerais
Hansens disease involves biological, cultural and social aspects in its dynamics and should be understood as a complex disease. Despite the advance of scientific knowledge, it remains as a public health problem in Brazil, with high detection and prevalence rates in some regions of the country. This situation suggests the existence of a gap between the scient

10. Caracterização de cepas de Escherichia coli contendo diferentes alelos rpoS. / Characterization of Escherichia coli strains carrying different rpos alleles.
Escherichia coli can be found in many different habitats and has to be prepared to survive and grow under unfavorable conditions. Bacteria adaptation to different growth conditions requires an efficient control of gene expression. One of the primary forms of gene expression control is the competition between different sigma factors for the binding to the cor

11. Retratamento endodôntico: casuística e comparação de dois métodos de diagnóstico por imagem / Endodontic retreatment: case studies and comparison of two methods of diagnosis by image
The radiographic test is an essential diagnosis component in the treatment of problems of endodontic origin. Despite the technical and scientific developments in endodontics, the number of endodontic retreatment continues high. In this scenario, Computerized Beam Cone Tomography (CBCT) is used to obtain three-dimensional images without distortions of structu

12. Controle de acesso baseado em biometria facial
Face recognition is one of the most ordinary and natural task carried out by humans. Even though it is a simple task, it has proved to be a major challenge for artificial intelligence and computer vision researchers. Researches on object detection and recognition, and more specifically those related to human face, has greatly increased their demand in recent
