Planejamento urbano e geração de empregos: A cidade de São Paulo (Brasil) nos anos 90

This paper attempts to show the convergence of principles between labor market politics and urban management, emphasizing it relationship with pro-market theories. Limits and possibilities of the application of this theoretical frame were investigated by examining the changes in both composition and stock of labor in three important business spaces in São Paulo: Central Area, Paulista Avenue and the new expansion front near Luiz Carlos Berrini and Águas Epraiadas avenues. Despite the claims of pro-market theoreticians, information provided by Labor Ministry showed that between 1996 and 2000, a re-arrangemenet of the workers contingent among the investigated areas occurred, instead of the expected growth. The favorable behavior registered in Berrini/ Águas Espraiadas, because of the bulky volume of investments, took place at the same time that a decrease of labor in the Downtown; meanwhile, in Paulista, a growth of the number of employees was observed, in spite of the landing less elevated of investments.

Dificuldades e alternativas encontradas por licenciandos para o planejamento de atividades de ensino de óptica para alunos com deficiência visual

Partial outcomes of a study aimed to verify future High School teachers performance during the development of a Teaching Practice undergraduate course. The student teachers were asked to plan, elaborate and teach, in a classroom situation, optics topics to a class which included visual handicapped pupils. Data analysis shows that the main difficulties found by the student physics' teachers are related to which approach will be used to perceive phenomena dependent on vision and also to the need to break away from traditional pedagogy.. On the other hand, as alternatives, future teachers have shown creativity in order to overcome passive aptitudes related to this educational problem, working out methodological strategies that do not require the knowing/seeing relation, as well as, emphasizing oral communication within the physics teaching context.

Morfologia e morfometria dos tipos de fibras do músculo reto abdominal de cadelas (canis familiaris) durante a gestação

The present paper deals with the evaluation of morphological and morphometric alterations of slow-twist (I) and fast-twitch (II) fibers of rectus abdominis muscle of adult female dog during pregestational phase, at 30 and 60 days of pregnancy and at 30 days after the parturition. At the every phases, using the open biopsy technique, muscle samples were collected. The samples were plunged. Histological sections were cut in a microtome. For general morphology, some sections were stained with HE. Subsequent sections were reacted for myofibrillar ATPase (m-ATPase), after alkaline (pH 10.4) and acid (pH 4.4) pre-incubations, in order to identificate type I and II fibers. In the pre-gestational phase, muscle tissue revealed to be composed by fibers with different diameters, presenting polygonal outlines and one or more periphery nuclei. At 30 days of pregnancy, muscle fiber characteristics were similar. At 60 days, in addition to the existence of normal fibers, polymorphic and small diameter fibers were frequent. At 30 days after the parturation, the morphology of muscle fiber were similar to that observed in the pre-gestational phase. In the four phases, type II fiber diameters were lager than type I. The diameters of both fiber types showed a significant reduction in the 30 days phase and a significative increasing at 60 days. The expansion of the abdominal wall during the pregnancy represents a chronic stimulus, induced changes in the morphology and in the fiber type diameters.

Quantificação do interferon-tau durante o reconhecimento materno da gestação em fêmeas bovinas Bos taurus indicus

During the critical period of the maternal recognition, which occurs between days 15 and 19 of pregnancy, the conceptus must competently synthesize molecules capable of blocking the synthesis of prostaglandin F2α (PGF2α) and luteolysis. In cattle, the major macromolecule involved in suck blockage is the protein interferontau (IFN-τ). During the critical period, failures in the recognition of pregnancy determine embryonic mortality on up to 40% of inseminated cows. Data about IFN-τ in Bos taurus indicus are still scarce. Objective of this study was to quantitatively evaluate the presence of IFN-τ during the critical period for maternal recognition of pregnancy in uterine flushings obtained in vivo by Foley catheter (Days 14, 16 and 18 post estrus) or post-mortem (Day 18 post estrus). Multiparous, cyclic or pregnant zebu cows (Bos taurus indicus) on days 14, 16 and 18 post estrus were used for in vivo or post mortem uterine flushing collection. In both cases, a Ringer solution was used to wash the uterus of cows. Uterine flushings were concentrated by ultrafiltration and lyophilized. Proteins were separated by one-dimensional electrophoresis (SDS-PAGE) in a 15% polyacrilamide gel. Interferontau quantification in uterine flushings was performed by western blotting and densitometry. Non-specific protein bands were observed in both in vivo and post mortem uterine flushings. Interferon-tau was detected only in uterine flushings obtained from pregnant cows post-mortem (P<0.05). Optical density of protein bands was not affected by the day of the critical period, state (cyclic or pregnant) or interaction day x state. There was no effect of the conceptus weight or progesterone concentration on the day of uterine flushing collection in the optical density of the IFN-τ protein band. It was concluded that the detection and quantification of IFN-τ in the uterine environment of zebu cows, in these experimental?conditions, is only possible in uterine flushings obtained post-mortem.

Planejamento agrícola e implantação de sistema de cultivo de cana-de-açúcar com auxílio de técnicas geoestatísticas

Sugarcane is one of the most important crops of the Brazilian agribusiness and this importance justifies the use of techniques that allow the implementation of cultivation systems capable of reducing the variability of soil characteristics and the establishment of efficient agricultural planning. The aim of the present work was the planning and implementation of cultivation systems for sugarcane using geostatistical techniques, in the Pereira Barreto region, SP. An area of 505 ha was mapped using the global positioning system (GPS) and a Digital Elevation Model was elaborated (MDE). Soil samples were collected for 0-0.25 m depth, in each 7 ha, for their chemical attributes and texture characterization. Data were analyzed by descriptive statistics and geostatistics. The determination of the spatial distribution of soil granulometric and chemical attributes allowed the allocation of the studied sugarcane varieties according to soil fertility and clay content. The kriging maps of soil granulometric and chemical attributes brought useful information to the establishment of production environments with different soil and crop managements. The identification of different environments by means of geostatistical techniques allowed the precise planning of the sugarcane cultivation, as well as the adequacy of fertilization practices and the allocation of suitable sugarcane varieties adapted to the conditions imposed by differences in the soil attributes.

Planejamento, síntese e avaliação farmacológica de compostos híbridos potencialmente ativos para o tratamento da anemia falciforme

Sickle cell disease (SCD) is a hereditary hemolytic anemia caused by the inheritance of one S hemoglobin gene from each ancestor. Patients with SCD present increased circulating levels of cytokines, including TNF-alpha (TNF-α). Hydroxyurea (HU) is the available therapeutically strategy for treatment; it acts as a source of nitric oxide and benefits patients by increasing the levels of fetal hemoglobin (HbF). Thus, within one research line that aims at finding new drugs, a series of compounds with TNF-α inhibition and nitric oxide donation properties have been synthesized in order to explore possible synergism of actions beneficial in the treatment of the disease. Six compounds were synthesized: five derivatives of organic nitrates and one of sulfonamide. The compounds, (1,3-dioxo-1,3-dihydro-2Hisoindol-2-yl) methyl nitrate (compound I); (1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) ethyl nitrate (compound II); 3-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound III);4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N-hydroxybenzenesulfonamide (compound IV); 4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound V) and 2-[4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) phenyl]ethyl nitrate (compound VI), were synthesized using linear synthetic methodology, with excellent overall yields. All compounds showed anti-inflammatory and analgesic effects with a reduction in 43%-65% of ear edema in mice and a reduction of 25%-42% of writhing induced by acetic acid. All compounds showed comparable reductions in the leukocyte infiltration capacity and ability to generate nitric oxide. The aryl compounds (III, IV and V) presented less mutagenic activity compared to compounds I, II and VI according to the salmonella mutagenicity assay (Ames test). Compounds IV and VI showed activity in K562 culture cells, with increases in gamma globin gene expression to levels higher than with hydroxyurea suggesting a potential to increase fetal hemoglobin. This data set characterizes new potentially useful drug candidates for the treatment of symptoms of sickle cell anemia.

Zoneamento geoambiental aplicado ao planejamento da gestão ambiental e territorial do município de Colorado D'Oeste, RO

This research is based on the physical characterization of the environment to support definition of the best land use for the county of Colorado D'Oeste, in State of Rondônia, Brazil. Remote sensing and geoprocessing techniques were applied to support the preparation of a Geoenvironmental Zoning, which was used to define strategies of territorial and environmental management in that county. Digital and analogical remote sensing products, acquired by satellites, and additional cartographic and thematic maps allowed a morphostructural analysis to define low and high structural associated study site tectonic. Subsequently, this information was used to support analysis of the physiographic compartmentation of the study area. Based on this study information, it is possible to define geoenvironmental subzones and local hidrological regime, soils, mineral components, texture, color, and sedimentary materials. By integrating previous described information, a synthesis cartographic map generated. Accordingly, this Cartographic Sheet spatially defined the best land use over the study area, indicates zones for conservation, agricultural, and regeneration (areas that should be recovered). Finally, the results of this research can contribute and support governmental and non-governmental organization and local communities could improve land use and soil management, avoiding natural resource destruction and future land scarcity in the county of Colorado D'Oeste.

Planejamento em saúde bucal no município de João Pessoa, Estado da Paraíba: o cirurgiãodentista enquanto protagonista da atenção básica

The aim was to identify the perception of Oral Health Planning (OHP) of basic care (BC) dental surgeons (DSs) in João Pessoa, Paraíba State, Brazil. Seventeen BC DSs from João Pessoa were interviewed. A qualitative analysis was performed using the Discourse of the Collective Subject (DCS) methodology. DCS obtained: Impact - My work is effective when the user's need remains at the BC. Social Control - The population participates in the organization of promotional activities, but I think it doesn't have enough maturity to opine on OHP. OHP Basis and Organization - The OHP has a diverse organization and is based on user needs. It can be concluded that the knowledge of the DSs on OHP is varied. There is limited understanding about problem-solving. Social control is considered incipient and weak. It is understood that the organization of the local OHP assumes a diverse character and should be based on user demands.

Perda e luto: Vivências de mulheres que interromperam a gestação por malformação fetal letal

The scope of this study was to investigate the grieving experiences of women who terminated pregnancies under judicial authorization, due to life-incompatible fetal malformation. Ten women attended in the Fetal Medicine Department of Botucatu Clinical Hospital participated in the study. Data collection was conducted by means of semi-structured interviews forty days after termination. The interviews were recorded and transcribed in full, with the data analyzed from the thematic content analysis perspective. The results revealed that the mothers sought explanations and meanings for the loss, with religious responses and self-blame being very frequent. The reports were marked by feelings of sadness, longing and sensations of emptiness due to the loss of the child, revealing the need of the mothers to dwell on the issue. The mothers were and continued to be linked to their children; the termination of the pregnancy, although being a choice to minimize the pain of an inevitable loss, did not spare the women from experiences of great suffering. The study includes input for the discussion and planning of health approaches and care for women who terminate their pregnancy due to lethal fetal malformation, by means of judicial authorization.
