Capital monopolista, ditadura e Estado no Brasil: o caso da trajetória da construtora Mendes Júnior

O artigo pretende analisar a relação entre capital e Estado no Brasil, problematizando a trajetória da construtora mineira Mendes Júnior, centrando em suas atividades ao longo da ditadura civil-militar brasileira (1964-1988), período de grande crescimento da empresa. Nossa hipótese é que essa empreiteira constitui um caso emblemático do capital monopolista gestado no Brasil ao longo do século XX, alimentado pelo fundo público e pelo protecionismo estatal implementado pelo regime autoritário. Dessa forma, analisamos o percurso da empresa enfatizando seu processo de crescimento e inserção junto às agências do Estado brasileiro. Concluímos que o processo de expansão da empresa se dá no compasso da afirmação do capital monopolista no Brasil, porém a construtora encontrou dificuldades em meio ao processo de transição política e durante a Nova República no país.

Growth and accumulation of nutrients in organic jambu

The objective of this study was to evaluate the growth and accumulation of nutrients in accessions of organic jambu. The experiment was conducted in the didactic garden of the Federal Institute of Pará, Campus Castanhal, in the period May and June 2015. The experimental design was a randomized complete block design with a 2 x 5 factorial arrangement with four replicates. The treatments were a combination of two jambu accessions (Purple Flower and Yellow Flower) and five sampling times (10, 18, 26, 34 and 42 days after transplanting - DAT). The period of greatest growth and nutrient demand was for access to Purple Flower from 18 to 34 DAT and for the Yellow Flower from 26 to 42 DAT. Nutrient accumulation by the two accesses of jambu, in decreasing order, was: potassium, nitrogen, calcium, magnesium and phosphorus.

PV technologies performance comparison in temperate climates

During the last decade, PV technology has been subject to a quick and remarkable improvement, affecting both the efficiency of modules and the manufacturing costs; during its period of greatest growth, the EU market was characterized by different major types of PV modules, but in many cases, due to the extremely rapid development of the sector, there is a lack of knowledge about the energy performance and behavior of such technologies under actual operating conditions. The aim of this work is thus to carry out a performance comparison of three different and representative PV technologies in temperate climatic conditions; in particular, the influence of climatic parameters on energy production was investigated, with a focus on the thermal and spectral analysis. The experimental results, referred to a monitoring period of one year, show a significant difference between the reference performances, rated under standard test conditions, and the actual daily/seasonal productivity, providing useful information about the different interaction with climate of the technologies tested.

Caring for children with IBD

Children are often regarded as the most important part of society because they represent the future. Because childhood is the period of greatest growth and development, optimizing their health outcomes could have a big impact on future public health. However, treating a child is not like treating a small adult. Congenital defects, genetic difference, and developmental issues are just some of the concerns that may require greater attention when caring for children than when caring for adults. Additionally, Klassen et al (2008) state that child healthcare providers must often rely on evidence that has been generated on adult populations. The authors explain that the problem with this is that the safety and efficacy profiles of medications may be significantly different for children than adults due to differences in developmental physiology and disease pathophysiology. Thus, there is a clear need to address the lack of randomized clinical trials of medications for children and ensure a standardization in the care of children. This is clearly the case in the management of children with irritable bowel syndrome (IBD).

Looking forward

It is with great pleasure that I am writing my first introductory editorial as the new editor of the Australian Occupational Therapy Journal. I am fortunate to be taking on this role after a period of great growth and development of the Journal which has ultimately led to the ISI listing. This listing is a wonderful achievement for Janet Fricke and the editorial team. This development well and truly positions the Journal on the international stage and we are likely to see an increase in the number and quality of submissions as a result. Gaining a reasonable impact factor which will be published in 2010 is the next challenge. Another exciting announcement is the introduction of a new annual award The Kryss McKenna First Time Writer's Award. This award was established by OT AUSTRALIA to honour the dedication and significant contribution made by Associate Professor Kryss McKenna to developing academic occupational therapy writers in Australia. It also acknowledges her long and productive association with the Australian Occupational Therapy Journal. The inaugural award will be presented at the National Conference. I encourage you all to attend the 23rd National Conference, be inspired, research and write, thus adding to our ever increasing evidence for practice. I would like to say a big thank you to reviewers, who are critical in maintaining a high standard of publications. The conference will be a great opportunity to meet with other reviewers and members of the Editorial team. We are always in need of experts to review for the Journal so if you would like to sign up you can do so by registering through manuscript central. I would also like to sincerely thank Janet and everyone involved in the Journal for supporting me in my new role.

Stereological study of acinar growth in the rat parotid gland induced by isoproterenol

The growth of the rat parotid gland induced by daily treatment with isoproterenol (IPR) for 2 weeks was investigated by stereological methods applied to light microscopy. After 7 days of treatment, the glandular mass presented a 286% growth, with the first 3 days being the period of greatest growth. Total acinar volume exhibited a 363% increase during the period from 0 to 7 days, while acinar-cell volume presented a 468% growth from 0 to 5 days of treatment. On the other hand, total acinar-cell number did not increase during the study period. Thus, under the conditions used, IPR-stimulated gland growth was essentially hypertrophic. However, a significant increase in the number of bipolar and multipolar mitoses was also observed, especially on the third and fifth days of treatment. As no increase in acinar-cell number occurred during growth, the presence of these mitoses suggests that cell death occurred during gland growth. On this basis, bipolar mitoses may occur to replace cells that probably degenerated during treatment, whereas multipolar mitoses may lead to the occurrence of polyploidy.

Destination Maintenance

Destinations rise and fall in popularity, and that pattern has given rise to the theory of the destination life cycle, which posits that each destination will enjoy a period of great growth followed by a period of stability and then one of decline. The decline occurs for many reasons, but improper maintenance of that destination is certainly one of them. On the other hand, maintaining the attractions of a destination would allow that destination to extend its popularity. A case in point is Schnebly Hill Road, a popular picnic spot amid the beautiful and dramatic scenery near Sedona, Arizona. Already experiencing degradation, Schnebly Hill will cease to be attractive to most visitors unless it is accorded some kind of protection. Moreover, the damage done to Schnebly Hill will reflect negatively on Sedona and the entire area.

Early stages of Purkinje cell maturation demonstrated by Thy-1 immunohistochemistry on postnatal rat cerebellum.

The cell surface glycoprotein, Thy-1, is present on Purkinje cells at birth, so allowing Thy-1 immunohistochemistry to demonstrate the final stage of migration and the transition to dendritic growth of these cells. In the most caudal lobule of the cerebellar cortex of the newborn rat, migrating Purkinje cells are found. These have a prominent process (up to 50 micron long) from which fine filopodia project, presumably sensing the environment in front of the cell. These cells are orientated tangentially, at right angles to the radial orientation they assume for dendritic growth. Strong Thy-1 labelling is found not only on their surface, but also on a cytoplasmic cap above the presumed leading pole of the nucleus. More rostrally in the cerebellar cortex, Purkinje cells arrive up to 3 days before birth and are quiescent until the postnatal development of their dendritic tree. At birth and during early postnatal periods a rounded cell is found with little cytoplasm; Thy-1 staining labels its surface and the fine processes which emanate from it. Such cells coexist with other Thy-1-positive Purkinje cells with more developed surface orientated processes. Even as early as the day of birth these fine processes cross the molecular layer and contact the lower level of the external granule layer. Orientated dendritic growth appears to occur by a selective thickening of these processes and a massive apical protrusion of intensely Thy-1-positive cytoplasm. The whole of the Purkinje cell surface membrane exhibits high levels of Thy-1 throughout dendritic growth and synaptogenesis, and cytoplasmic antigen is prominent during the period of greatest growth. Thy-1 is also found on the neurons of the deep cerebellar nuclei, and is seen transiently on Golgi interneurons. High levels of the antigen are present on blood vessels and choroid plexus at birth but are lost from these structures over the first 2 postnatal weeks.

Crayfish Production: A Reflection of Community Energetics

ABSTRACT Within any particular geographic area certain species of crayfish predominate: reasons for this predominance may be found in the demographic response of crayfish populations to such factors as nutrient addition, predation (including exploitation by man), or interaction with other crayfish species. Polytrophic crayfish utilize both primary and detrital production, both of which are governed by nutrient availability and energy distribution. The result is a sharply pulsed cycle of food availability at high latitudes in contrast to a more continuous cycle at low latitudes. Through modifications in their demographic response, life cycles of crayfish are adjusted to both the environmental conditions and resulting food availability prevalent at various latitudes. Often the end result is a match of young-of-the-year production to food production at each latitude. Most year to year differences in the cohort (year class) production of various species are due to fluctuations in mortality rates rather than to adjustments in growth or fecundity rates. The highest production rates are achieved by species with low mortality rates that coincide with the period of greatest growth (early age/size groups). Major impacts on these production rates are: exploitation, nutrient addition, and/or addition of new crayfish species. Exploitation, particularly in high latitudes. can increase the influence of environmental conditions on cohort mortality rates. Nutrient addition further modifies the cohort survival of certain species, depending on the latitude as well as on the presence of opportunistic competitors which may be better adjusted bioenergetically to exploit the prevailing food production cycle.

The regulation of 3-hydroxy-3-methylglutaryl-CoA reductase activity, cholesterol esterification and the expression of low-density lipoprotein receptors in cultured monocyte-derived macrophages.

Human blood monocytes cultured in medium containing 20% whole serum showed the greatest activity of 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase and [14C]acetate incorporation into non-saponifiable lipids around the 7th day after seeding, the period of greatest growth. Although there was enough low-density lipoprotein (LDL) in the medium to saturate the LDL receptors that were expressed by normal cells at that time, HMG-CoA reductase activity and acetate incorporation were as high in normal cells as in cells from familial-hypercholesterolaemic (FH) patients. Both the addition of extra LDL, which interacted with the cells by non-saturable processes, and receptor-mediated uptake of acetylated LDL significantly reduced reductase activity and increased incorporation of [14C]oleate into cholesteryl esters in normal cells and cells from FH patients ('FH cells'), and reduced the expression of LDL receptors in normal cells. Pre-incubation for 20h in lipoprotein-deficient medium apparently increased the number of LDL receptors expressed by normal cells but reduced the activity of HMG-CoA reductase in both normal and FH cells. During subsequent incubations the same rate of degradation of acetylated LDL and of non-saturable degradation of LDL by FH cells was associated with the same reduction in HMG-CoA reductase activity, although LDL produced a much smaller stimulation of oleate incorporation into cholesteryl esters. In normal cells pre-incubated without lipoproteins, receptor-mediated uptake of LDL could abolish reductase activity and the expression of LDL receptors. The results suggested that in these cells, receptor-mediated uptake of LDL might have a greater effect on reductase activity and LDL receptors than the equivalent uptake of acetylated LDL. It is proposed that endogenous synthesis is an important source of cholesterol for growth of normal cells, and that the site at which cholesterol is deposited in the cells may determine the nature and extent of the metabolic events that follow.

Ecology of Hexagenia Naiads (Insecta-Ephemeridae) in an Oklahoma Reservoir

A stratified, random sampling schedule of benthic samples was initiated to contribute information to the life history of a mayfly, Hexagenia, in Oklahoma. Sampling was carried out from March, 1966, to February, 1967, in Boomer Lake, Payne County. The Hexagenia population consisted of at least two species, H. limbata (Serville) and H. bilineata (Say), which together comprised a monthly mean of from 19 to 56% of the total number of organisms collected. Mean biomass of Hexagenia in the lake was greatest in May (8.2 kg/ha) and lowest in September (1.8 kg/ha). Mean numerical standing crop was lowest in August (148/M2) and greatest in December (968/M2). Period of greatest growth was approximately from March until December during 1966. During winter months, mean biomass per individual remained relatively constant. Evidence for a one-year life cycle is presented. Anoxic conditions occurred in Boomer Lake but it was not determined, from collected samples, whether or not Hexagenia populations were affected. Abundance of Hexagenia was found by statistical analysis to vary independently of depth of water and near-bottom water temperature.

A closer look at the non‐television household

The growth in percentage of American homes with television over the past dozen years has outstripped even the adjectives used to describe the phenomenon. Although the period of greatest growth was between 1950 and 1955, the proportion of U.S. homes with television has climbed from two out of every three in June of 1955 to nine out of ten today. The non‐television owner has become something of a rare bird, not necessarily needing sanctuary, but certainly worthy of study. At the time this research was performed, the Census Bureau reported 85% set ownership in the sample area (a figure in excellent agreement with findings in the present study). This study was financed in part by a grant‐in‐aid from the National Educational Television and Radio Center. Field work was conducted by students of Professor Ralph O. Nafziger. Dr. Richard F. Carter, now of Stanford University, also contributed to the study.

The digestibility of bur clover as affected by exposure to sunlight and rain

Abstract does not appear. First page follows. The principal forage plants of California foothill and valley ranges are annuals.3 They germinate with the coming of the fall rains and make, during the winter, an amount of growth that varies according to moisture and temperature conditions. From February to May is usually the period of greatest growth. When the rains cease and moisture is depleted, the forage matures and dries. Stock is then either maintained on the dry feed or moved to summer ranges in the high mountains. In the latter case, the stock is brought to the lower ranges in the early fall and subsists on the old dry feed until rains bring on new forage. The changes in the plants from the early vegetative stage to the dried condition involve marked changes in chemical composition and nutritive value. After drying, the feed is subjected to the processes of weathering. Studies by Woodman and others(1), (2), (3) on the nutritive value of pasture have shown that young pasture grass is in digestible composition a “watered concentrate” rather than a roughage. They found that 70 per cent of the organic matter was digestible and that the small amount of fiber which it contained was 80 per cent digestible. The immature grass contained approximately 20 per cent digestible protein with a nutritive ratio of about 1:3.
