    Full Text Available Se realizó la caracterización mensual de las agregaciones de merluza de cola usando registros acústicos obtenidos por equipos SIMRAD EK60 y ES60 a bordo de tres embarcaciones multipropósito que operaron en la Unidad de Pesquería Centro-Sur durante el año 2003, para lo cual se emplearon descriptores morfológicos y batimétricos. En cuanto a su morfología, las agregaciones mostraron una amplia variabilidad, explicada por su nivel de cohesión y tendencia a formar agregaciones de gran extensión horizontal, mientras que batimétricamente se determinó que el 90% de éstas se ubicaron preferentemente entre 300 y 450 m. Existe evidencia de asociación entre diversos descriptores y estos a su vez con otros factores como talla media, temperatura del agua, latitud y mes, lo que permite describir apropiadamente la forma de las agregaciones y su ubicación en la columna de agua. Algunas relaciones relevantes corresponden a: profundidad de las agregaciones respecto a la profundidad del fondo (r = 0,55, altitud de las agregaciones respecto a la profundidad del fondo (r = 0,72, altitud de las agregaciones respecto al índice de profundidad relativa (r = -0,98 y profundidad de las agregaciones respecto a la talla media (r = 0,66.A monthly characterization of Chilean hoki aggregations was done using acoustic records ob-tained with SIMRAD EK60 and ES60 devices aboard three multipurpose vessels that operated in the central-southern fishery unit during 2003; this considered morphological and bathymetric descriptors. The wide mor-phological variation of the aggregations was explained by their cohesión level and tendency to form large horizontal aggregations whereas, bathymetrically, 90% of the aggregations were located between 300 and 450 m. Evidence of associations between various descriptors was found, and these were, in turn, associated with other factors such as mean size, water temperature, latitude, and month, allowing an adequate description of the

    Full Text Available Se analizaron los cambios espacio-temporales de las capturas de merluza de cola obtenidas por la flota industrial de cerco en la zona centro-sur de Chile (34°-41°30'S, para revisar la hipótesis de migración hacia el norte de la fracción juvenil de merluza de cola en primavera. Se utilizaron datos de bitácoras de pesca del periodo 1986-2003, y a partir de éstos se calcularon centros de gravedad de las capturas y su varianza. Se postula que si la flota sigue el comportamiento migratorio de la fracción juvenil, se esperaría que los centros de gravedad de las capturas migren latitudinalmente de sur a norte conforme la estación de pesca avanza. No obstante, sólo se encontró cuatro casos en que ocurrió una migración hacia el norte de los centroides. Más bien, los centros de gravedad se presentan estacionarios, al interior de cada temporada de pesca. Se postula que existe una fracción juvenil residente que sólo incrementa su accesibilidad y vulnerabilidad en aguas superficiales en primavera debido al régimen ambiental, que se caracteriza por la dominancia de eventos de surgencia y no a una migración de sur a norte.We analyzed spatio-temporal changes in Patagonian grenadier catches by the purse-seine fleet off central-southern Chile (34°-41°30'S in order to check the hypothesis that the juvenile fraction of the population migrates northward in spring. Log-book data from 1986 to 2003 were used to calculate the center of gravity of and variance of each catch. We proposed that, if the fleet follows the migratory behavior of the juvenile fraction, the centers of gravity of the catches will migrate from south to north as the fishing season progresses. Nevertheless, the centers of gravity migrated northward in only four cases. Unexpectedly, the centers of gravity remained stationary within each fishing season. Now we propose that, in spring, a resident juvenile fraction of Patagonian grenadier increases its accessibility and vulnerability

    Full Text Available Important nursery grounds for Patagonian grenadier (Macruronus magellanicus are located mainly in the Northwest Patagonian Inner Sea (42ºS-44ºS, from which juvenile must to disperse or migrate offshore, then along the Chilean coast either northward or southward. The objective of this paper was to estimate northward spring juvenile migration of the Patagonian grenadier from nursery to feeding areas, which are located near Talcahuano (35º00’S-37º10’S. Length-frequency data (LFD were obtained from an acoustic survey carried out in November 1999, which covered from 35ºS to 47ºS. Generalized linear model was used to describe the presence of juvenile per latitude and depth, and to infer the origin and displacement of juveniles. Subsequently, LFD data were grouped according to latitudinal strata. Grouped LFD were decomposed into normal component groups, from which mean, standard deviation and proportion were estimated from the mixed LFD. The average length of the identified groups were sorted from south to north, and linked to compute significant increment in fish length and age per kilometers. The length increment per time was not due to growth, rather they was due to spatial displacement of juvenile from southern nursery grounds to northern feeding areas. Although homing to feeding areas and/or high residency (partial migration have been postulated, it seems that recruitment of juveniles to northern feeding areas are origintaed from NPIS nurseries. The West Wind Drift Current seems to be the main drive for dispersion of Patagonian grenadier to recruit northward in open waters along the continental shelf.

    Avian pox is an enveloped double-stranded DNA virus that is mechanically transmitted via arthropod vectors or mucosal membrane contact with infectious particles or birds. Magellanic Penguins (Spheniscus magellanicus) from two colonies (Punta Tombo and Cabo Dos Bahías) in Argentina showed sporadic, nonepidemic signs of avian pox during five and two of 29 breeding seasons (1982-2010), respectively. In Magellanic Penguins, avian pox expresses externally as wart-like lesions around the beak, flippers, cloaca, feet, and eyes. Fleas (Parapsyllus longicornis) are the most likely arthropod vectors at these colonies. Three chicks with cutaneous pox-like lesions were positive for Avipoxvirus and revealed phylogenetic proximity with an Avipoxvirus found in Black-browed Albatross (Thalassarche melanophrys) from the Falkland Islands in 1987. This proximity suggests a long-term circulation of seabird Avipoxviruses in the southwest Atlantic. Avian pox outbreaks in these colonies primarily affected chicks, often resulted in death, and were not associated with handling, rainfall, or temperature.

    Otoliths from blue grenadier (Macruronus novaezelandiae), which had been aged previously by annuli analysis, were analysed for the naturally occurring radionuclides 210 Pb and 226 Ra in an attempt to independently verify their age. It is concluded that the radiometric technique could not be applied to determine age because the results showed that 226 Ra was not incorporated at a constant rate throughout the life of M. novaezelandiae. Uptake of 226 Ra was greater in juveniles than in adult fish. This was probably due to the juvenile phase inhabiting inshore/estuarine waters. 20 refs., 1 tab., 2 figs

    On September 10, 1991, the International Bird Rescue Research Center (IBRRC) was contacted by Dee Boersma, professor of zoology at the University of Washington. An oil spill from an unknown source had affected large numbers of magellanic penguins (Spheniscus magellanicus) returning to breeding colonies along the coast of southern Argentina. Dr. Boersma had been studying the penguins at Punta Tombo since 1982. It wasn't unusual for some of the penguins to arrive oiled, but this year the numbers of oiled birds were up considerably. In the week of September 14 to 20, a survey of 239 kilometers of coastline (about one-third of the affected area) spotted 16,350 penguins with some degree of oiling

    Lipid deterioration of two lean fish species, saithe (Pollachius virens) and hoki (Macruronus novaezelandiae), during frozen storage at -20 and -30°C (up to 18months) was studied. Lipid composition, lipid oxidation and hydrolysis, and sensory attributes were evaluated on both light and dark muscles of the fish species. Results showed significant lipid deterioration with extended storage time, but lower storage temperature showed significantly more preservative effects. A marked difference was observed between the composition of dark muscle of hoki and saithe. Polyunsaturated fatty acids were the predominant lipids in dark muscle of saithe, while monounsaturated fatty acids were predominant in dark muscle of hoki. Further, the hydrolytic activity differed greatly between dark muscle of hoki and saithe, with significantly lower activity observed in hoki. Present results indicate that both tertiary lipid oxidation and hydrolysis products are appropriate for assessing lipid deterioration of saithe and hoki light muscle during frozen storage.

    Full Text Available The beneficial health effects of a diet rich in n-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA have been extensively researched in recent years. Marine oils are an important dietary source of n-3 LC-PUFA, being especially rich in two of the most important fatty acids of this class, EPA (eicosapentaenoic acid; 20:5n-3 and DHA (docosahexaenoic acid; 22:6n-3. Oils rich in n-3 LC-PUFA are prone to oxidation that leads to loss of product quality. Alaskan pollock (Gadus chalcogrammus Pallas, 1814 and New Zealand’s hoki (Macruronus novaezelandiae Hector, 1871 are the highest volume fisheries of their respective countries. Both produce large quantities of fishery byproducts, in particular crude or unrefined n-3 LC-PUFA containing oils. Presently these oils are used as ingredients for animal feed, and only limited quantities are used as human nutritional products. The aim of this research was to investigate the applicability of short path distillation for the purification of pollock and hoki oil to produce purified human-grade fish oil to meet quality specifications. Pollock and hoki oils were subjected to short path distillation and a significant decrease in free fatty acids and lipid oxidation (peroxide and para-anisidine values products was observed. Purified oils met the Global Organization for EPA and DHA Omega-3 (GOED standard for edible fish oils.

    Full Text Available The tongue of birds presents diversified morphologic characteristics, related directly their feeding habits and may be adapted to food capture. Penguins of the Spheniscidae family are pelagic birds that are totally adapted to the marine environment.  The objective of this study was to describe the morphology of the tongue in Magellanic penguins (Spheniscus magellanicus. In order to investigate these characteristics, six tongues of juvenile S. magellanicus were collected and their morphology analyzed macroscopically and microscopically.  The tongue of the Magellanic penguin has a fusiform shape with a round apex that is narrower than the root, following the shape of the beak.  The epithelium of the tongue of the Magellanic penguin showed to be stratified and very keratinized, with the presence of lingual papillae that showed a caudally inclined apex. The neighboring connective tissue showed absence of mucous glands. The cartilaginous skeleton was observed in the medial region of the tongue, extending from the base to the apex. The structure of the tongue of the Magellanic penguin showed to be similar to that of other penguin species, but also showed peculiar characteristics that were not observed in other bird families.

    This report presents a new case of mucormycosis encountered in penguin characterized by morphological variation of hyphae and presence of sporangia with numerous sporangiospores. A 4.5-year-old Magellanic penguin (Spheniscus magellanicus) died after exhibiting anorexia, poor nutritional condition and dyspnea. Multiple nodular lesions were observed in the thoracic and abdominal regions. Histopathologically, hyphae of various sizes were seen in the lungs, air sac and nodular lesions. Myriad sporangiospores and several sporangia were observed in/around the bronchi or parabronchi. The very narrow and short hyphae in the nodules were not consistent with the characteristics of Mucorales. However, for most hyphae, including those in the nodules, sporangiospores and sporangia, immunohistochemistry revealed Mucorales-positive reactions. In addition, these fungi were identified as Rhizomucor pusillus by gene analysis.

    Magellanic penguins (Spheniscus magellanicus) are non-breeding winter visitors to the Brazilian coast. In 2008 and 2010, plastic items and other marine debris were found in the stomachs and intestines of 15% of 175 dead penguins collected in the Lagos Region of the state of Rio de Janeiro. One bird had its stomach perforated by a plastic straw, which may have caused its death. There are few records of penguins ingesting plastic litter, but previous studies have found similar levels of debris ingestion among Magellanic penguins stranded on the Brazilian coast (35.8% of 397 birds). The high incidence of marine debris in this species in Brazil may result at least in part from the predominance of juveniles reaching these waters, as juvenile penguins may have a broader diet than adults. It is unclear to what extent plastic ingestion affects the mortality rate in this species and whether the incidence in stranded birds reflects that in the entire population. The present study addresses the increasing impact of plastic debris on marine life. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Magellanic penguins (Spheniscus magellanicus) are native to Argentina, Chile and the Falkland Islands. Magellanic penguins are highly susceptible to blood parasites such as the mosquito-borne Plasmodium spp., which have been documented causing high morbidity and mortality in zoos and rehabilitation centres. However, to date no blood parasites have been detected in wild Magellanic penguins, and it is not clear whether this is reflective of their true absence or is instead related to an insufficiency in sampling effort or a failure of the diagnostic methods. We examined blood smears of 284 Magellanic penguins from the Argentinean coast and tested their blood samples with nested polymerase chain reaction tests targeting Haemoproteus, Plasmodium, Leucocytozoon and Babesia. No blood parasites were detected. Analysing the sampling effort of previous studies and the climatogeography of the region, we found there is strong basis to conclude that haemosporidians do not infect wild Magellanic penguins on the Argentinean coast. However, at present it is not possible to determine whether such parasites occur on the Chilean coast and at the Falkland Islands. Furthermore, it is troubling that the northward distribution expansion of Magellanic penguins and the poleward distribution shift of vectors may lead to novel opportunities for the transmission of blood parasites.

    We undertook a light and scanning electron microscopic study of the eye in the Magellanic penguin (Spheniscus magellanicus). The anatomical peculiarities of the eyeball shape in Sphenisciformes have been previously described by others; here, we show that they are accompanied by several modifications in the organization of the anterior segment of the eye. The main change was found in the portion of opaque sclera extending from the cornea to the anterior border of the scleral ossicles, which was much broader than in other avian eyes. This scleral region was made of a very dense fibrous tissue and was as difficult to cut as the ossicles. The corneo-scleral boundary was also different from that of other birds, since the aqueous humor channel and the pectinate ligament were located 1.0-1.5 mm posterior to the cornea. The osseous ring was formed by 13 bones, including three pairs of over- and underplates. There was a single ciliary muscle, with meridionally oriented striated fibers. They were inserted on a circumference along the boundary between the fibrous sclera and the ossicles, far away from the wall of the aqueous humor channel. On their posterior end, the muscle fibers formed a tendinous structure attached to the inner surface of the sclera and to the outer surface of the ciliary body. Only short zonular fibrils were observed. These anatomical features are probably relevant for the adaptation of penguin eyes to vision on land and in the aquatic environment.

    The effect of massive neutrinos on the growth of cold dark matter perturbations acts as a scale-dependent Newton's constant and leads to scale-dependent growth factors just as we often find in models of gravity beyond General Relativity. We show how to compute growth factors for ΛCDM and general modified gravity cosmologies combined with massive neutrinos in Lagrangian perturbation theory for use in COLA and extensions thereof. We implement this together with the grid-based massive neutrino method of Brandbyge and Hannestad in MG-PICOLA and compare COLA simulations to full N -body simulations of ΛCDM and f ( R ) gravity with massive neutrinos. Our implementation is computationally cheap if the underlying cosmology already has scale-dependent growth factors and it is shown to be able to produce results that match N -body to percent level accuracy for both the total and CDM matter power-spectra up to k ∼< 1 h /Mpc.

  20. From mammals back to birds: Host-switch of the acanthocephalan Corynosoma australe from pinnipeds to the Magellanic penguin Spheniscus magellanicus.

    Trophically-transmitted parasites are regularly exposed to potential new hosts through food web interactions. Successful colonization, or switching, to novel hosts, occur readily when 'donor' and 'target' hosts are phylogenetically related, whereas switching between distantly related hosts is rare and may result from stochastic factors (i.e. rare favourable mutations). This study investigates a host-switching event between a marine acanthocephalan specific to pinnipeds that is apparently able to reproduce in Magellanic penguins Spheniscus magellanicus from Brazil. Detailed analysis of morphological and morphometrical data from acanthocephalans from penguins indicates that they belong to Corynosoma australe Johnston, 1937. Partial fragments of the 28S rRNA and mitochondrial cox1 genes were amplified from isolates from penguins and two pinniped species (i.e. South American sea lion Otaria flavescens and South American fur seal Arctocephalus australis) to confirm this identification. Infection parameters clearly differ between penguins and the two pinniped species, which were significantly lower in S. magellanicus. The sex ratio of C. australe also differed between penguins and pinnipeds; in S. magellanicus was strongly biased against males, while in pinnipeds it was close to 1:1. Females of C. australe from O. flavescens were smaller than those from S. magellanicus and A. australis. However, fecundity (i.e. the proportion of fully developed eggs) was lower and more variable in females collected from S. magellanicus. At first glance, the occurrence of reproductive individuals of C. australe in Magellanic penguins could be interpreted as an adaptive colonization of a novel avian host through favourable mutations. However, it could also be considered, perhaps more likely, as an example of ecological fitting through the use of a plesimorphic (host) resource, since the ancestors of Corynosoma infected aquatic birds.

    Tree cavities can provide critical roosting sites for cavity-using vertebrates. These sites can directly affect productivity and survival of bats. Histiotus magellanicus, one of the bat species with the southernmost distribution in the world, is suspected to use tree cavities, under bark, caves and human buildings for roosting. We document the first records of this bat roosting in tree cavities created by both cavity-facilitators (i.e., excavators) and tree-decay processes on standing dead an...

    Research was performed to increase our understanding of male Magellanic penguin (Spheniscus magellanicus) reproductive biology and to develop artificial insemination (AI) technology to assist with maintaining the species' genetic diversity. Seminal traits were characterized from seven males with noncontaminated ejaculates (n = 123) displaying high in vitro motion parameters, membrane integrity, and morphology. Seven females were maintained in nest sites that permitted visual, auditory, and tactile contact with their paired male but not copulation for 18.3 ± 2.4 days before egg lay. After cloacal AI (2.6 ± 0.4 inseminations/female) with semen chilled for up to 20.5 hr at 5°C, all females produced one to two fertile eggs, with the first oviposition occurring within 7 days of plasma progesterone concentrations exceeding 0.8 ng/ml. Overall fertility was 91.7%, hatchability was 63.6%, and genetic analyses confirmed that all embryos and hatchlings were sired by AI males. The heterospermic AI design demonstrated that eggs were fertilized by spermatozoa chilled for 1.5-19.8 hr before AI and were laid 4.5-11.5 days post AI. These results contribute new data on Magellanic penguin sperm biology and demonstrate that high fertility rates after AI of chilled semen can be achieved with females remaining in proximity to their paired mate.

  8. Creation and validation of a novel body condition scoring method for the magellanic penguin (Spheniscus magellanicus) in the zoo setting.

    2015-11-01

    This research aims to validate a novel, visual body scoring system created for the Magellanic penguin (Spheniscus magellanicus) suitable for the zoo practitioner. Magellanics go through marked seasonal fluctuations in body mass gains and losses. A standardized multi-variable visual body condition guide may provide a more sensitive and objective assessment tool compared to the previously used single variable method. Accurate body condition scores paired with seasonal weight variation measurements give veterinary and keeper staff a clearer understanding of an individual's nutritional status. San Francisco Zoo staff previously used a nine-point body condition scale based on the classic bird standard of a single point of keel palpation with the bird restrained in hand, with no standard measure of reference assigned to each scoring category. We created a novel, visual body condition scoring system that does not require restraint to assesses subcutaneous fat and muscle at seven body landmarks using illustrations and descriptive terms. The scores range from one, the least robust or under-conditioned, to five, the most robust, or over-conditioned. The ratio of body weight to wing length was used as a "gold standard" index of body condition and compared to both the novel multi-variable and previously used single-variable body condition scores. The novel multi-variable scale showed improved agreement with weight:wing ratio compared to the single-variable scale, demonstrating greater accuracy, and reliability when a trained assessor uses the multi-variable body condition scoring system. Zoo staff may use this tool to manage both the colony and the individual to assist in seasonally appropriate Magellanic penguin nutrition assessment. © 2015 Wiley Periodicals, Inc.

    Eight captive female Magellanic penguins (Spheniscus magellanicus) were monitored over a 10week period, commencing at 5weeks prior to egg lay (EL), to increase our understanding of the species' reproductive biology. Females in cordoned nest sites underwent cloacal artificial insemination (AI) every 4-7days with different semen donors for each insemination. The EL interval was 97.9±3.6h (range: 84-108h) and paternity analyses revealed that conceptive inseminations occurred from 11.5 to 4.5days before oviposition. A biphasic pattern of estradiol, testosterone, progesterone and the biochemical analytes triglyceride, iron, calcium and phosphorus occurred in relation to EL, with values increasing (P<0.05) to maximal concentrations during the three weeks preceding oviposition, then decreasing (P<0.05) rapidly after oviposition completion. In comparison with post-lay (baseline) values, concentrations of estradiol and testosterone relative to the first oviposition were elevated at Week-5, and those of triglyceride, a yolk formation index, as well as iron, calcium and phosphorus, became elevated at Week-4 (P<0.05). Collective data indicate an estimated total egg formation interval of 29days, with oviducal transit of the ovulated ovum occurring over the majority of the ∼4day EL interval. These findings indicate that egg formation is prolonged with folliculogenesis initiated at 5weeks or more prior to oviposition. Consequently, the period of folliculogenesis and egg formation is estimated to overlap with the final ∼3weeks that wild females spend at sea prior to returning to land for breeding.

    Full Text Available In this paper, we describe two new species of Syndesmis living in Pseudechinus magellanicus in the Southwest Atlantic Ocean. The new species have a long stylet in the male reproductive system, which is different from that of the known species of the genus. Specimens of Syndesmis selknami n. sp. have a ∼220-μm-long stylet (∼1/3 of the body length, 0.69 mm. This ratio is unique because only four species (Syndesmis echinorum, Syndesmis rubida, Syndesmis inconspicua and Syndesmis echiniacuti have similar stylet lengths but are larger in body sizes (3–5 mm. Specimens of Syndesmis aonikenki n. sp. have a ∼148-μm-long stylet (∼1/10 of the body length, 1.11 mm. Syndesmis pallida has a similar ratio but the uterus is located posteriorly, and the filament glands are very small and located in the posterior region of the body.

    Science.gov (United States)

    Townsend, S

    Social marketing entails promoting the appropriate and quality product to be sold in the right places at the right price. Even though mass media advertisement of condoms is forbid in Zaire, condoms have been effectively promoted and sold in the country using alternate approaches. 8 million units of the condom, Prudence, were sold in 1990, and Prudence has become the generic name for condoms in the Zaire. Noting that Coca-Cola, beer, and cigarettes may be purchased virtually ubiquitously, commercial outlets and local traders were enlisted to sell condoms at reduced prices on the market. Reduced price sales are possible since donor and government agencies provide the condoms to wholesalers and merchants free of charge. The successful social marketing of condoms expands condom availability to a greater segment of a country's population while recovering some public sector costs and shifting health care away from the public sector. Condoms are especially promoted to high risk groups such as commercial sex workers and their clients in Zaire. Similar programs have been inspired in 10 African countries including Cameroon and Burundi, as well as in Brazil, Haiti, and India. Prevention programs in Latin America and Asia will benefit from these program experiences in Africa. In closing, the article notes the need for an adequate and predictable commodity supply in attaining effective social marketing. Marked program success may, however, lead to sustainability problems.

    Enamel demineralization was studied over periods related to normal use of an orange juice, an apple juice, Pepsi Cola and Diet Pepsi Cola. Rectangular blocks of intact human enamel (3 mm x 3 mm) were cut from teeth, coated with nail varnish except for the enamel surface and exposed to the drinks for 2, 4, 5, 6 or 40 minutes. The amount of calcium released from the enamel into solution was determined with the use of an atomic absorption spectrophotometer. The results showed the following degree of enamel demineralization: Pepsi Cola = orange juice greater than apple juice greater than Diet Pepsi Cola. The results suggest that diet colas are less demineralizing than other acid drinks, and complementary plaque studies indicate that they are also less cariogenic. The study emphasized the importance of acid-type, buffer capacity, pH and the presence of other components on the degree of enamel demineralization.

    Ocean acidification, the progressive change in ocean chemistry caused by uptake of atmospheric CO2, is likely to affect some marine resources negatively, including shellfish. The Atlantic sea scallop (Placopecten magellanicus) supports one of the most economically important single-species commercial fisheries in the United States. Careful management appears to be the most powerful short-term factor affecting scallop populations, but in the coming decades scallops will be increasingly influenced by global environmental changes such as ocean warming and ocean acidification. In this paper, we describe an integrated assessment model (IAM) that numerically simulates oceanographic, population dynamic, and socioeconomic relationships for the U.S. commercial sea scallop fishery. Our primary goal is to enrich resource management deliberations by offering both short- and long-term insight into the system and generating detailed policy-relevant information about the relative effects of ocean acidification, temperature rise, fishing pressure, and socioeconomic factors on the fishery using a simplified model system. Starting with relationships and data used now for sea scallop fishery management, the model adds socioeconomic decision making based on static economic theory and includes ocean biogeochemical change resulting from CO2 emissions. The model skillfully reproduces scallop population dynamics, market dynamics, and seawater carbonate chemistry since 2000. It indicates sea scallop harvests could decline substantially by 2050 under RCP 8.5 CO2 emissions and current harvest rules, assuming that ocean acidification affects P. magellanicus by decreasing recruitment and slowing growth, and that ocean warming increases growth. Future work will explore different economic and management scenarios and test how potential impacts of ocean acidification on other scallop biological parameters may influence the social-ecological system.

Using Web of Science Core Collection database, we retrieved all studies declaring receipt of direct funding from the Coca-Cola brand, published between 2008 and 2016. Using conservative eligibility criteria, we iteratively removed studies and recreated Coca-Cola's transparency lists using our data. We used network analysis and structural topic modelling to assess the structure, organization and thematic focus of Coca-Cola's research enterprise, and string matching to evaluate the completeness of Coca-Cola's transparency lists. Three hundred and eighty-nine articles, published in 169 different journals, and authored by 907 researchers, cite funding from The Coca-Cola Company. Of these, Coca-Cola acknowledges funding forty-two authors (Coca-Cola Company appears to have failed to declare a comprehensive list of its research activities.

  16. Paralytic shellfish toxins in the sea scallop Placopecten magellanicus on Georges Bank: Implications for an offshore roe-on and whole scallop fishery

    2014-05-01

    To protect public health from the potential risk of paralytic shellfish poisoning (PSP) in sea scallops, Placopecten magellanicus, from the Atlantic offshore U.S. waters of Georges Bank, harvesting of roe-on or whole scallops is banned. Only adductor muscles may be sold if harvested from Georges Bank, Gulf of Maine, or the PSP closure areas as far west as 71° West Longitude. Given the limited toxicity data available for sea scallops from this region both prior to and subsequent to implementation of this management strategy, this study sought a more extensive spatial and temporal evaluation of sea scallop gonad and viscera toxicities that would inform management decisions related to the roe-on and whole scallop fishery. Both overall toxicity and toxin composition were measured for sea scallop gonads and viscera collected from 232 stations in 2007 and 23 in 2010. Overall toxicity was assessed using two screening methods: field-deployable Jellett Rapid Tests (JRT) and quantitative, laboratory-based receptor binding assays (in 2007). Additionally, a quantitative liquid chromatography with fluorescence detection (LC-FD) method was used to determine toxin composition and overall toxicity (in 2010). The at-sea qualitative JRT screening tool results, whereby a positive indicated the sample contained at least 40 μg saxitoxin (STX) equivalents 100 g-1, were often inconsistent with results obtained using the quantitative methods. Sea scallop viscera toxicity represented the majority of toxin load in the organism and was often in excess of the regulatory guidance level. Sea scallop gonads accounted for a small percentage of total toxicity, but at times reached unsafe levels. Toxin composition in both the gonads and viscera was dominated by STX and gonyautoxin 2/3, as has been reported in previous studies. No predictive indices of gonad toxicity were found. Results at this time do not support a roe-on or whole scallop fishery on Georges Bank. While access restrictions to

    Drinks that contain phosphoric acid have been shown to have erosive effects and cola drinks are strongly acidic (pH 2.5). Gingivitis may be caused by dietary acids. Therefore, this study analyses the interaction of Coca Cola consumption and oral mucosal damage. Thirty rats were divided into three groups of 10. The animals received saline (pH 7.0) or HCl acid buffered to pH 2.6 or Coca Cola (pH 2.6) per os with 24-h free access to these solutions. A biopsy was taken from the front of the gingiva and the tongue. Histopathological analysis showed no specific lesion and there were no differences among saline, Coca Cola and HCl groups. Flow cytometric analysis was used to assess proliferative activity. In the HCl acid and Coca Cola groups, cell cycle analysis showed that the effects of Coca Cola and HCl acid in inducing oral mucosal damage are similar. In both Coca Cola [G0/G1, 70.38+/-7.9; S, 28.06+/-10.13; G2/M, 1.62+/-2.80; proliferative index (PI), 28.68+/-7.981 and HCI (G0/G1, 67.7+/-18.9; S, 27.8+/-17.5; G2/M, 4.4+/-3.8; PI, 30.9+/-20.98), the rat cell population G0/G1 and G2/M phases were found to be low (p Coca Cola and HCl acid have similar proliferative and regenerative effects on oral mucosa, and it is possible that their regenerative effects are caused as a result of an irritant effect.

    Laboratory experiments can improve student interest in science. However, the contrary effect could occur if they are not well designed and seem tedious, too laborious, and disconnected from daily life. Cola beverages are one of the most widely consumed drinks and are most popular among students. Much attention is being paid to possible consequences of excessive consumption for human health. Intensive efforts are being made to assess the erosive potential for teeth because of the beverages' acidity (1, 2); adverse effects secondary to high caffeine intake (e.g., hypertension, allergic reactions, gastrointestinal disturbances) (3 - 5); and adverse effects on calcium metabolism due to their high phosphoric acid content, which combined with low dietary calcium intake could increase the risk of suffering from bone diseases (6 - 9). We propose here the quantification of the phosphorus content in this kind of drinks by a different procedure from that previously described by Murphy in this Journal (10). We think this laboratory experiment will seem very interesting to students.

    2000-03-01

    In ancient times, the main problem was to get food. Nowadays the difficulty is to decide for or against some foodstuff. In industrialized countries, this abundance led to the fact that people eat differently from what they should. Traditional populations were subject to periods of feast and famine. Those with a metabolism which stored energy with high energetic efficiency had a survival advantage. This is called the 'thrifty' genotype hypothesis. With the secured supply of calories, coupled with a sedentary lifestyle, the thrifty genotype becomes disadvantageous, causing obesity. Industrialization or 'cola-colonization' also leads to a dramatic increase in obesity and non-insulin dependent diabetes mellitus in developing countries. The spread of fast food restaurants all over the world has changed modern nutrition fundamentally. Influence begins early in childhood. Advertising concentrates on the selling of image over substance. However, fast food contains high levels of fat, especially trans fatty acids. Higher consumption of trans fatty acids was associated with a higher incidence of and mortality from coronary heart disease.

    We present the COmoving Lagrangian Acceleration (COLA) method: an N-body method for solving for Large Scale Structure (LSS) in a frame that is comoving with observers following trajectories calculated in Lagrangian Perturbation Theory (LPT). Unlike standard N-body methods, the COLA method can straightforwardly trade accuracy at small-scales in order to gain computational speed without sacrificing accuracy at large scales. This is especially useful for cheaply generating large ensembles of accurate mock halo catalogs required to study galaxy clustering and weak lensing, as those catalogs are essential for performing detailed error analysis for ongoing and future surveys of LSS. As an illustration, we ran a COLA-based N-body code on a box of size 100 Mpc/h with particles of mass ≈ 5 × 10{sup 9}M{sub s}un/h. Running the code with only 10 timesteps was sufficient to obtain an accurate description of halo statistics down to halo masses of at least 10{sup 11}M{sub s}un/h. This is only at a modest speed penalty when compared to mocks obtained with LPT. A standard detailed N-body run is orders of magnitude slower than our COLA-based code. The speed-up we obtain with COLA is due to the fact that we calculate the large-scale dynamics exactly using LPT, while letting the N-body code solve for the small scales, without requiring it to capture exactly the internal dynamics of halos. Achieving a similar level of accuracy in halo statistics without the COLA method requires at least 3 times more timesteps than when COLA is employed.

    The present paper describes the outbreak of health complaints that occurred in Belgium, in June 1999, among schoolchildren and members of the general public in relation to the consumption of Coca-Cola and other soft drinks. The outbreak took place in the wake of a major food crisis, caused by PCB/dioxin contamination of animal feed, that had erupted shortly before. The clinical features (absence of serious poisoning) and epidemiological characteristics of the Coca-Cola outbreak pointed to mass sociogenic illness, and no subsequent toxicological or other data have refuted this hypothesis.

    2002-01-01

    The Coca-Cola travel health kit has been used for about one decade for international travelers and required evaluation to see if the items contained were appropriate for the employees. Two hundred thirty-four travelers were sampled and filled out a voluntary survey including questions about demographic information, travel history, and usage and value of the contents of the travel health kit. One hundred eighty-one surveys were returned; 65% of the respondents were male, and the majority of travelers were between the ages of 36 and 45 years. The most useful items were analgesics and medications used for gastrointestinal problems. In general, the items identified as being the least useful were those requiring specialized use by a medical practitioner, such as needles and syringes. Suggestions of items to be added to the kit included vitamins, cough drops, sleep aids, and eye drops. A surprising result that Coca-Cola employees expressed the desire for brand name rather than generic items. Evaluation of the Coca-Cola Company travel health kit revealed it to be very useful to most corporate travelers. Suggestions that were made will be taken into consideration in designing a new kit, and consideration is being given to whether a basic travel health kit should be provided to which travelers can add other items depending on their personal needs.

    The effect of an acidic beverage (Coca-Cola) on the pharmacokinetics of a single dose of carbamazepine was studied. In a two-way cross-over design with a 1 week washout period, 10 healthy volunteers were randomized to received 200 mg carbamazepine orally with 300 ml of Coca-Cola or water. Blood samples were collected at 0, 0.5, 1, 2, 3, 6, 9, 12, 24, 48 and 72 h after drug administration. Plasma carbamazepine levels were higher with Coca-Cola as compared to water. The AUC0-infinity and Cmax of carbamazepine were significantly enhanced after Coca-Cola while tmax was achieved earlier with Coca-Cola. The results of the study indicate that concomitant administration of Coca-Cola enhances the rate and extent of absorption of carbamazepine.

    Bezoars are concretions of foreign bodies found in the gastrointestinal tract. In the past, most common method for the treatment of bezoar was surgical management. However, the current treatment methods include chemical dissolution and endoscopic mechanical lithotripsy. There were few reports on the treatment of phytobezoars by nasogastric Cola lavage. However, there was no report succeeded by oral route alone. In our two cases, phytobezoars were treated by oral administration of Coca-Cola. Our patients drank 700-800 mL of Coca-Cola daily, and after two months, complete dissolutions of bezoars were achieved. We report two cases of phytobezoars completely treated by drinking Coca-Cola.

    Colorectal fecaloma is hardening of feces into lumps of varying size that is much harder in consistency than a fecal impaction. Complications of colorectal fecaloma include ulceration, bleeding, perforation and obstruction of the colon. Most fecalomas are successfully removed by conservative treatment with laxatives, enemas and rectal evacuation to relieve fecal impaction. When conservative treatments have failed, a surgical intervention may be needed. Herein, we report a case of 4.7 cm sized sigmoid fecaloma showing no response to conservative treatments that was successfully removed by endoscopic fragmentation with Coca-Cola injection instead of surgery.

  9. Absorption and subjective effects of caffeine from coffee, cola and capsules.

    Science.gov (United States)

    Liguori, A; Hughes, J R; Grass, J A

    1997-11-01

    Coffee is often perceived as producing greater pharmacological effects than cola. The present study compared the magnitude and rapidity of peak caffeine levels and subjective effects between coffee and cola. Thirteen users of both coffee and cola (mean daily caffeine consumption = 456 mg) ingested 400 mg caffeine via 12 oz unsweetened coffee, 24 oz sugar-free cola or 2 capsules in a random, double-blind, placebo-controlled, within-subjects design. Subjects provided a saliva sample and completed subjective effect scales 15 min before and 30, 60, 90, 120, 180 and 240 min after ingestion. Mean peak saliva caffeine levels did not differ between coffee (9.7 +/- 1.2 micrograms/ml) and cola (9.8 +/- 0.9 micrograms/ml) and appeared to be greater with these beverages than with the capsule (7.8 +/- 0.6 micrograms/ml; p = NS). Saliva caffeine levels peaked at similar times for coffee (42 +/- 5 min) and cola (39 +/- 5 min) but later for capsule (67 +/- 7 min; p = 0.004). There was no main effect of vehicle or interaction of vehicle and drug on magnitude of peak effect or time to peak increase on self-report scales. In summary, peak caffeine absorption, time to peak absorption, and subjective effects do not appear to be influenced by cola vs. coffee vehicle. Perceived differences in the effects of coffee vs. cola may be due to differences in dose, time of day, added sweetener, environmental setting or contingencies.

  10. Cola beverage consumption delays alveolar bone healing: a histometric study in rats

    2010-06-01

    Full Text Available Epidemiological studies have suggested that cola beverage consumption may affect bone metabolism and increase bone fracture risk. Experimental evidence linking cola beverage consumption to deleterious effects on bone is lacking. Herein, we investigated whether cola beverage consumption from weaning to early puberty delays the rate of reparative bone formation inside the socket of an extracted tooth in rats. Twenty male Wistar rats received cola beverage (cola group or tap water (control group ad libitum from the age of 23 days until tooth extraction at 42 days and euthanasia 2 and 3 weeks later. The neoformed bone volume inside the alveolar socket was estimated in semi-serial longitudinal sections using a quantitative differential point-counting method. Histological examination suggested a decrease in the osteogenic process within the tooth sockets of rats from both cola groups, which had thinner and sparser new bone trabeculae. Histometric data confirmed that alveolar bone healing was significantly delayed in cola-fed rats at three weeks after tooth extraction (ANOVA, p = 0.0006, followed by Tukey's test, p < 0.01. Although the results of studies in rats cannot be extrapolated directly to human clinical dentistry, the present study provides evidence that cola beverage consumption negatively affect maxillary bone formation.

    Although bezoar dissolution by Coca-Cola® has been described in case reports and case series, to the best of our knowledge, the usefulness of other cola products such as Pepsi-Cola® has never been reported in the English literature. An 86-year-old Taiwanese man was diagnosed with a gastric bezoar. Endoscopic fragmentation with a polypectomy snare was attempted twice but failed to remove the bezoar. Subsequently, 500 mL of Pepsi NEX Zero® was administered daily for 4 days via nasogastric tube. The bezoar was softened and successfully fragmented by the polypectomy snare and needle-knife devices on the third attempt. This report presents the first case of a gastric bezoar successfully treated by endoscopic fragmentation in combination with Pepsi-Cola® administration, suggesting the possible utility of cola beverages in bezoar treatment, regardless of product brands.

    To investigate the mechanism of phytobezoar dissolution by Coca-Cola(®), persimmon phytobezoar pieces removed from a 60-year-old Japanese woman were analyzed by energy dispersive X-ray spectroscopy. The amount of calcium significantly decreased after dissolution treatment using Coca-Cola(®), suggesting a potential contribution of calcium to dissolution mechanisms. Moreover, immersion in Coca-Cola(®) for 120 hours on the exterior surface revealed that Coca-Cola(®) did not permeate persimmon phytobezoars. This is the first study to investigate the mechanisms of persimmon phytobezoar permeability and dissolution induced by Coca-Cola(®).

    Full Text Available La actividad agrícola del estado de Sonora se caracteriza por ser de las más desarrolladas del país, es altamente productiva, tecnificada y generadora de divisas. Para mantener las demandas del mercado ha sido necesario implementar cultivos intensivos y el uso indiscriminado de agroquímicos, lo que ha provocado la contaminación del suelo. Los plaguicidas organoclorados (POC’s fueron utilizados desde l950 hasta 1991, principalmente en el cultivo de algodón. En países industrializados fueron prohibidos o restringidos desde 1970 y en México a partir de 1991. Los POC’s representan un riesgo para la salud y el medio ambiente por su toxicidad, bioacumulación, volatilidad y persistencia; es por ello, que a través del Convenio de Estocolmo, los países adheridos están comprometidos a su reducción o eliminación. El objetivo del presente trabajo fue verificar la presencia de los POC’s en suelos de las principales zonas agrícolas (ZA del estado de Sonora. Se extrajeron 17 POC’s por el método de dispersión de matriz en fase sólida (DMFS y análisis por cromatografía de gases. Se muestrearon 45 campos donde se recolectaron cinco muestras de suelo (capa superficial y 60 cm de profundidad y se entrevistó a los encargados para conocer los cultivos históricos y aplicación de POC’s. El 100% de los entrevistados manifestó haber utilizado POC’s. Los porcentajes de recuperación fueron del 78 al 116% con CV < 20%. Los residuos de POC’s estuvieron en un rango de no detectados (nd a 45.75 µg kg-1. En Caborca: 1.22-9.62, Hermosillo: nd-7.49, Magdalena: 0.73-24.40, Ures: nd 18.78 y Guaymas: 1.43-45.75. Los de mayor incidencia fueron: DDE, endosulfán, γ-clordano, heptacloro epóxido y endrín. La correlación positiva entre la materia orgánica y los POC’s, puede propiciar su acumulación en los suelos agrícolas analizados.

  3. Wine and Coca Cola: Serendipity and Entrepreneurial success

    Wyatt, Philip

    2007-03-01

    Starting a new company from scratch depends critically on identifying a product for which there will be enough demand to generate a profit after a reasonable time period. Many start-ups nowadays obtain early Government grants or contracts (e. g. the so-called SBIR programs), but until such contracts begin (if ever!) to provide positive cash flow, a source of other funds become essential. Despite contracts, venture capital, and some friends willing to ``gamble,'' our first entrepreneurial venture ended not with a bang, but a whimper! We had chosen the wrong market. On the day before the company closed its doors, an unanticipated event occurred. We had opened a few bottles of wine for our final farewell but, as we began drinking, we decided to study their laser-scattering properties with our unappreciated and failed instrumentation. The resulting press coverage of a paper reporting that ``tasting'' was phenomenal, though it was published too late to save the company. Starting a second entrepreneurial venture was far more difficult as the first ``angels'' were nowhere to be found. A forgotten proposal by that failed first venture was suddenly funded providing, thereby, the means to start the second. As the second venture began, the success of the wine paper suggested that trying the same method with cola drinks might prove interesting. A new paper reporting on those results was immediately picked up by Applied Optics for an issue cover. At first, a particular cola manufacturer was not amused. However, it soon recognized the significance of laser scattering and began to contribute to the Company's support. Complemented by their largesse and the newly funded contract, the Company's instrumentation commercialization programs became sharply focused: refine the development and sale of a new type of absolute light scattering photometer incorporating a laser. We never looked back.

    2015-01-01

    Full Text Available Kola nut is chewed in many West African cultures and is used ceremonially. The aim of this study is to investigate some biological effects of Cola nitida’s bark after phytochemical screening. The bark was collected, dried, and then powdered for the phytochemical screening and extractions. Ethanol and ethyl acetate extracts of C. nitida were used in this study. The antibacterial activity was tested on ten reference strains and 28 meat isolated Staphylococcus strains by disc diffusion method. The antifungal activity of three fungal strains was determined on the Potato-Dextrose Agar medium mixed with the appropriate extract. The antioxidant activity was determined by DPPH and ABTS methods. Our data revealed the presence of various potent phytochemicals. For the reference and meat isolated strains, the inhibitory diameter zone was from 17.5±0.7 mm (C. albicans to 9.5±0.7 mm (P. vulgaris. The MIC ranged from 0.312 mg/mL to 5.000 mg/mL and the MBC from 0.625 mg/mL to >20 mg/mL. The highest antifungal activity was observed with F. verticillioides and the lowest one with P. citrinum. The two extracts have an excellent reducing free radical activity. The killing effect of A. salina larvae was perceptible at 1.04 mg/mL. The purified extracts of Cola nitida’s bark can be used to hold meat products and also like phytomedicine.

    Foodborne nanoparticles (NPs) have drawn great attention due to human health concerns. This study reports the detection of the presence of fluorescent NPs, about 5 nm, in two of the most popular beverages, Coca-Cola (Coke) and Pepsi-Cola (Pepsi). The NPs contain H, C and O, three elements with a tunable emission and with a quantum yield of 3.3 and 4.3% for Coke and Pepsi, respectively. The presence of sp 3 -hybridized carbon atoms of alcohols and ethers bonds was confirmed by NMR analysis. The NPs can be taken up by living cells and accumulate within cell membrane and cytoplasm. Evaluation of the acute toxicity of the NPs revealed that the BALB/c mice appeared healthy after administration of a single dose of 2 g kg -1 body weight. Analysis of glutamate pyruvate transaminase (GPT), glutamic oxaloacetic transaminase (GOT), urea and creatinine showed that there were statistically, but not biologically, significant differences in some of these biochemical parameters between the test and control groups. No obvious organ damage or apparent histopathological abnormality was observed in the tested mice. The biodistribution study in major organs indicated that the NPs were easily accumulated in the digestive tract, and they were able to cross the blood-brain barrier and dispersed in the brain. In vitro digestion of the NPs showed a significant fluorescence quenching of the NPs. This work represents the first report of foodborne fluorescent NPs present in Coke and Pepsi, and provides valuable insights into physicochemical properties of these NPs and their toxicity characteristics both in vitro and in vivo.

    Full Text Available Cola nitida Linn (Sterculiaceae is an economic plant widely distributed throughout West Africa and possibly other parts of Africa.Members are malvalves because of their lobular nature. Because of its ubiquity, the plant plays an important role in commerce, and in social activities where it is casually eaten without prescription or restriction. The ethnopharmacological effects of bolus ingestion of 30g of Cola nitida was investigated on visually acute and healthy volunteers in order to determine its ocular implications or effects. Results showed that Cola nitida had no effecton the pupil diameter, visual acuity and intraocular pressure but improved the near point of convergence by 43% and increased the amplitude of accommodation by 11% while existing heterophorias are ameliorated. The stimulating effect of Cola nitida might overcome asthenopic symptoms with convergence insufficiency and allows near work to be donewithout stress. Somnolence and ocular muscle imbalance common features of the elderly canbe ameliorated or relieved.

    This study was carried out to evaluate the influence of an acidic beverage (Coca-Cola) on the pharmacokinetics of phenytoin in rabbits. In a cross-over study, phenytoin was given orally at a dose of 30 mg/kg and blood samples were taken at different intervals from 0-24 h. After a washout period of 7 days, Coca-Cola (5 ml/kg) was administered in combination with phenytoin (30 mg/kg) and blood samples were taken at various time intervals from 0-24 h. The same rabbits continued to receive Coca-Cola (5 ml/kg) for another 7 days. On the 8th day, Coca-Cola (5 ml/kg) in combination with phenytoin (30 mg/kg) was administered and blood samples were taken at similar intervals. Plasma was separated and assayed for phenytoin by high performance liquid chromatography (HPLC) and various pharmacokinetic parameters were calculated. It was concluded that an acidic beverage (Coca-Cola) increases the extent of absorption of phenytoin by significantly increasing the Cmax and AUC(o-á) of phenytoin. These results warrant the reduction of phenytoin dose when administered in combination with Coca-Cola to avoid any toxicity. (c) 2003 Prous Science

    Colonic obstruction is a relatively common condition in emergency care, with a mortality rate of up to 20%. In 90% of cases it results from colonic or rectal adenocarcinoma, volvulus, or stenosis secondary to diverticular disease. When fecal impaction is the underlying cause, the condition is usually managed conservatively, but may on occasion become complicated and even require surgical intervention. Based on the proven efficacy of Coca-Cola® to dissolve gastric phytobezoars, we report a case of colonic obstruction secondary to sigmoid fecaloma. A 58 years old woman arrived at the Emergency Room (ER) with persistent constipation for the last six days. An abdominal CT scan showed a large fecal mass at the sigmoid colon with retrograde dilated colonic loops. Cleansing enemas and oral lactulose were administered, which failed to resolve the clinical presentation, so we then proceeded to inject Coca-Cola® within the fecaloma using a sclerosing needle, and then washed the fecaloma surface also with Coca-Cola®. After a few minutes we started to fragment the fecalith, the consistency of which had been notably decreased. The use of Coca-Cola® for gastric washes in the management of phytobezoars is well established. Since fecaliths are partly composed of these same substances than phytobezoars, the use of Coca-Cola® might well be warranted against them as in our patient, without surgery. Our case report is the second one published in the literature, in which Coca-Cola® helped solve colonic obstruction secondary to fecaloma.

    The study was aimed at determining the effect of Coca-Cola on the pharmacokinetics of ibuprofen in rabbits. In a cross-over study, ibuprofen was given orally in a dose of 56 mg/kg, prepared as 0.5% suspension in carboxymethyl cellulose (CMC) and blood samples (1 ml) were drawn at different time intervals from 0-12 hr. After a washout period of 7 days, Coca-Cola in a dose of (5 ml/kg) was administered along with ibuprofen (56 mg/kg) and blood samples were drawn from 0-12 hr. To these rabbits, 5 ml/kg Coca-Cola was administered once daily for another 7 days. On 8th day, Coca-Cola (5 ml/kg) along with ibuprofen (56 mg/kg), prepared as a suspension was administered and blood samples (1 ml each) were drawn at similar time intervals. Plasma was separated and assayed for ibuprofen by HPLC technique and various pharmacokinetic parameters were calculated. The Cmax and AUC0-alpha of ibuprofen were significantly increased after single and multiple doses of Coca-Cola, thereby indicating increased extent of absorption of ibuprofen. The results warrant the reduction of ibuprofen daily dosage, frequency when administered with Coca-Cola.

    Full Text Available The Coca-Cola Company sold drink concentrates and licensed rights to its trademarked brands to contracted bottlers who produced and sold bottled drinks in designated geographic areas around the world, including Colombia, beginning in 1927. The franchise system enabled international expansion without large corporate growth or direct local employment allowing the company to externalize liability and financial risk. The franchise system helped the company situate the production of Coca-Cola within local economies, conscripting local elites and workers into its industry, and negotiating its representational forms to fit local contexts. The Coca-Cola Company thus benefited from the economic and political power of both the U.S. and the Colombian elite as it established its business in the country beginning in 1927. Examining print advertising from the 1920s and 1940s, the papers of Coca-Cola executives, and publications of the U.S. multinational and its Colombian franchise bottler, this article argues that The Coca-Cola Company tenuously constructed its industry, products, and brands as simultaneously global and local. While localizing the Coca-Cola industry, products, and brand, the company alluded to its modernity and global popularity, available for purchase by enterprising merchants and thirsty consumers in Colombia.

The aerobic exercise was performed for 5 days per week throughout the study (24 weeks and the exercise intensity was gradually increased during the first 8 weeks until it reached 20 meters / minute for 30 minutes. Body weight, lipid profile, glycemia, plasma creatinine levels, atherogenic index of plasma (AIP and systolic blood pressure (SBP were determined. After 6 months all rats were sacrificed. A kidney histopathological score was obtained using a semiquantitative scale. Glomerular size and glomerulosclerosis were estimated by point-counting. The oxidative stress and pro-inflammatory status were explored by immunohistochemistry. A one way analysis of variance (ANOVA with Tukey-Kramer post-hoc test or the Kruskal-Wallis test with Dunn's post-hoc test was used for statistics. A value of p < 0.05 was considered significant.At 6 months, an increased consumption of cola soft drink was shown in CS and CR compared with water consumers (p<0.0001. Chronic cola consumption was associated with increased plasma triglycerides, AIP, heart rate, histopathological score, glomerulosclerosis, oxidative stress and pro-inflammatory status. On the other hand, moderate exercise prevented these findings. No difference was observed in the body weight, SBP, glycemia, cholesterol and plasma creatinine levels across experimental groups.This study warns about the consequences of chronic consumption of cola drinks on lipid metabolism, especially regarding renal health.

The purpose of this study was to explore selected soft drinks (Coca-Cola Classic (registered) , Diet Coke (registered) , Coke Zero (registered) ) as indicators of bioaccessible uranium and other trace elements (As, Ce, Cu, La, Mn, Ni, Pb, Th, Y, Zn) in contaminated soils of the Mary Kathleen uranium mine site, Australia. Data of single extraction tests using Coca-Cola Classic (registered) , Diet Coke (registered) and Coke Zero (registered) demonstrate that extractable arsenic, copper, lanthanum, manganese, nickel, yttrium and zinc concentrations correlate significantly with DTPA- and CaCl 2 -extractable metals. Moreover, the correlation between DTPA-extractable uranium and that extracted using Coca-Cola Classic (registered) is close to unity (+ 0.98), with reduced correlations for Diet Coke (registered) (+ 0.66) and Coke Zero (registered) (+ 0.55). Also, Coca-Cola Classic (registered) extracts uranium concentrations near identical to DTPA, whereas distinctly higher uranium fractions were extracted using Diet Coke (registered) and Coke Zero (registered) . Results of this study demonstrate that the use of Coca-Cola Classic (registered) in single extraction tests provided an excellent indication of bioaccessible uranium in the analysed soils and of uranium uptake into leaves and stems of the Sodom apple (Calotropis procera). Moreover, the unconventional reagent is superior in terms of availability, costs, preparation and disposal compared to traditional chemicals. Contaminated site assessments and rehabilitation of uranium mine sites require a solid understanding of the chemical speciation of environmentally significant elements for estimating their translocation in soils and plant uptake.

    Gastric phytobezoars represent the most common bezoars in patients with poor gastric motility. A variety of dissolution therapies and endoscopic fragmentation techniques have been evaluated as conservative treatment so as to avoid surgery. To investigate the effectiveness of Coca-Cola for gastric phytobezoars dissolution. We performed a systematic search to identify publications on gastric phytobezoars to assess the efficacy of Coca-Cola as a dissolution therapy. Diospyrobezoars, formed after persimmon ingestion, are a distinct type of phytobezoars characterized by their hard consistency. Thus, these two subgroups of bezoars were compared in terms of successful dissolution. Over a 10-year period (2002-2012), 24 papers including 46 patients have been published. In 91.3% of the cases, phytobezoar resolution with Coca-Cola administration was successful, either as a single treatment (50%) or combined with further endoscopic techniques, whereas only 4 patients underwent surgery. Phytobezoars were more likely to dissolve after initial attempt with Coca-Cola compared with diospyrobezoars (60.6% vs. 23%, P = 0.022). Coca-Cola alone is effective in gastric phytobezoar dissolution in half of the cases and, combined with additional endoscopic methods, is successful in more than 90% of them. © 2012 Blackwell Publishing Ltd.

    Full Text Available Due to the large consumption of soft drinks in Brazil and worldwide in recent years and considering that some of the components present in their composition pose potential risks to human health, the aim of this study was to evaluate the cytotoxic and mutagenic potential of specific cola and grape-flavored soft drink brands. Bone marrow cells of Wistar rats were initially treated by gavage with one single dose of Cola or Grape soft drink, which was next offered ad libitum (instead of water for 24 hours. A negative control treatment was performed by administering one single dose of water and a positive control administering cyclophosphamide intraperitoneally. Statistical analysis showed that the Cola and Grape soft drinks studied were not cytotoxic. However, the Cola soft drink proved mutagenic in this experiment treatment time. Therefore, this study serves as a warning about the consumption of Cola-flavored soft drink and for the need for further subchronic and chronic studies on soft drinks in order to evaluate the long term mutagenic and cytotoxic effects of these substances.

    Full Text Available Objective: To report a rare case of hypokalemic rhabdomyolysis induced by the heavy and prolonged ingestion of cola-based beverages, and its uneventful recovery after kalemia normalization. Methods: We report a 38-year-old Caucasian male presented in our emergency room with a recent and progressive weakness of the lower limbs proximal muscles. Results: A dietary history revealed a prolonged ingestion of cola-based beverages. Blood tests showed severe hypokalemia and marked increase in serum creatine phosphokinase. The analysis of cerebrospinal fluid resulted normal. Electromyography was suggestive for a myopathy. The clinical, laboratory and neurophysiological data were evocative for a cola-induced hypokalemic rhabdomyolysis. After kalemia normalization, the improvements of the electromyographic findings paralleled the clinical recovery. Conclusion: Chronic consumption of large amount of cola-based soft drinks may result in severe symptomatic hypokalemia, eventually leading in turn to myopathy. To our knowledge, this is the first description of the electromyographic findings of the cola-induced hypokalemic rhabdomyolysis. An early diagnosis and a prompt treatment appear to be crucial for a benign clinical course.

    Full Text Available Garcinia cola Heckel, an angiospermae belonging to the  family Guttiferae, is known in commerce as bitter cola. It is a plant found in the West African subregion, mostly in moist conditions, and often in association with Cola acuminata. The seeds are highly valued ingredients in African ethonomedicine. The seeds have several social uses and applications in folk medicine. These seeds are ordinarily chewed by the local people without prescription or restriction. In an in vivo case control study, the effects of Garcinia cola on some visual functions: pupil diameter, near point of convergence (NPC, amplitude of accommodation (AA, intraocular pressure (IOP, visual acuity (VA and habitual phoria; following bolus ingestion of 20 g was undertaken using healthy visually active volunteers. Results showed that bolus ingestion of Garcinia cola constricted the pupil by 68%, reduced the NPC by 28%, increased the AA by 17.8% at peak effect and decreased the intraocular pressure by 31% without affecting the distance and near VA. The lateral phoria at far and near tended towards esophoria. Possibly the miotic effect and reduction in IOP could be of benefit to patients with raised IOP where conventional drugs may not be effective. Also it is possible that the effects on phoria could be exploited in oculomotor function in combination with visual training.

    Full Text Available Para 2011, estavam previstos R$ 570 milhões ao Programa de Subvenção ao Prêmio do Seguro Rural (PSR, mas apenas R$ 253,4 milhões foram alocados ao Programa em função de contingenciamentos do governo. Apesar disso, foi possível segurar 5,6 milhões de hectares com uma importância segurada de R$ 7,3 bilhões. Mas qual deveria ser o volume de recursos direcionados ao PSR para que todo o crédito de custeio das lavouras pudesse ser coberto pelo mercado segurador? O estudo apresenta uma metodologia para calcular qual deve ser o valor orçamentário médio do PSR para cobrir cem por cento do custeio das lavouras. Para 2011, os resultados sugerem que o volume de recursos deveria ter sido quatro vezes maior do que o valor empenhado. Ademais, os resultados foram desagregados por estado e por culturas agrícolas. A importância do PSR para a massificação do seguro rural é indiscutível. Porém, além dos recursos do PSR estarem subdimensionados, outro problema ameaça a continuidade do Programa. Pelo terceiro ano consecutivo, o PSR tem sofrido graves contingenciamentos que têm impactado negativamente o mercado. Portanto, fica evidente a necessidade de maior esforço do governo federal em ampliar os recursos da subvenção e destiná-los única e integralmente ao PSR.

    Full Text Available Este trabalho analisa as diferenças no estado de saúde entre e dentro dos grupos de ocupados agrícolas e não agrícolas no Brasil, utilizando medidas de autoavaliação do estado de saúde captadas no suplemento da PNAD (Pesquisa Nacional por Amostra de Domicílios de 2008. As análises baseiam-se na composição socioeconômica dos ocupados agrícolas e não agrícolas e nas estimativas de equações simultâneas para captar as relações não lineares entre saúde, renda e jornada de trabalho. Um dos pressupostos do trabalho é que a baixa prevalência de saudáveis entre os ocupados agrícolas estaria associada, sobretudo, à composição socioeconômica desse grupo, e não à maior insalubridade a que os ocupados das atividades agrícolas estariam submetidos em condições socioeconômicas semelhantes às dos não agrícolas. Analogamente, a desigualdade no estado de saúde seria menor entre os ocupados agrícolas devido aos hábitos mais homogêneos, não só no que se refere ao tipo de atividade, mas também em relação à qualidade de vida e ao acesso a uma série de itens de consumo, típico das localidades menos desenvolvidas onde as atividades agrícolas prevalecem.This paper analyzes differences of health conditions between and within agricultural and non-agricultural workers in Brazil. Self-reported health measures of the Health Supplement of Pesquisa Nacional por Amostra de Domicílios (PNAD, from 2008, are used. Results are based on the description of the socioeconomic characteristics of each group of employees and on estimates of a simultaneous equation to measure non-linear relations between health conditions, income and work hours. The main hypothesis is that the lower prevalence of workers with good health among agricultural workers is mainly due to socioeconomic characteristics of this group and not necessarily to higher insalubrious conditions that such workers would be submitted to in equivalent socioeconomic conditions

    Large gastric phytobezoars may occur in patients with gastric dysmotility disorders. Treatment options include dissolution with enzymes, endoscopic fragmentation with removal or aspiration, and surgery. We report our experience with nasogastric cola lavage therapy. Over an 8-year period, five consecutive patients were referred to our unit for endoscopic treatment of large gastric phytobezoars. They included one patient with lobectomy for lung cancer and four patients with diabetic gastroparesis. An initial attempt of endoscopic fragmentation and removal was unsuccessful. Patients were treated with 3 l of Coca-Cola nasogastric lavage over 12 h. Nasogastric lavage was very well tolerated by the patients. Complete phytobezoar dissolution was achieved in one session in all cases. There were no procedure-related complications. The dissolution of large gastric phytobezoars with cola nasogastric lavage is a safe, rapid and effective method. Patients may be treated in the medical ward, avoiding therapeutic endoscopy or surgery.

    Our laboratory recently reported that a 3-month exposure of rats to cola-like beverages induced sex hormone changes. The aim of the study was to investigate the effects of various types of Coca-cola intake with different composition for 6 months on oxidative status in testes and testosterone in adult male rats. Fifty adult male Wistar rats were divided into control group drinking water, and groups drinking different Coca-cola beverages (regular Coca-cola, Coca-cola caffeine-free, Coca-cola Light and Coca-cola Zero). Oxidative and carbonyl stress markers were measured in the testicular tissue to assess oxidative status together with testicular and plasma testosterone. StAR expression in testes as a marker of steroidogenesis was quantified. No significant differences were found between the groups in any of the measured parameters. In conclusion, oxidative and carbonyl stress in testicular tissue were not influenced by drinking any type of Coca-cola. Additionally, testosterone in testes and in plasma, as well as testicular StAR expression were comparable among the groups. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available

    Com base nas reflexões de Mikhail Bakhtin (1988 sobre cronótopo e nos estudos dos semióticos, principalmente no que tange ao percurso passional do sujeito, analisamos propagandas impressas e comerciais televisivos da Coca-Cola. O objetivo principal é traçar a trajetória discursiva da Coca-Cola desde sua entrada no Brasil, em 1941, até a campanha Gostoso é viver, lançada em 2001. O discurso da Coca-Cola apresenta valores positivos como a alegria, emoção e prazer. Entretanto, são eliminados valores negativos e ocultados interditos, como: Coca-Cola é um produto norte-americano e industrializado, portanto, não é natural, engorda e vicia. Constrói-se, assim, um discurso que privilegia aspectos temáticos voltados para os estados passionais eufóricos (paixão, emoção, alegria. A Coca-Cola também reforça a idéia de que está presente em todo tempo e lugar. Assim, as categorias espaço-temporais são elementos importantes para a construção de sentido de suas propagandas. Reafirmando os mesmos valores e mantendo as categorias cronotópicas para a construção de sentido de suas propagandas, a Coca-Cola consolida a idéia de onipotência, ou seja, ela tem o "poder" de refrescar, trazer alegria, provovar emoção e satisfazer prazeres. Cria-se, assim, um estilo, isto é, uma identidade calcada em categorias divinas, tais como onipresença e onipotência.

    The purpose of this study was to determine the rate of change in indentation hardness of enamel in permanent teeth exposed to Coca-Cola. In a further experiment, the ability of a commercially available artificial saliva to remineralize enamel treated with Coca-Cola was tested. Ten enamel specimens were randomly chosen to be treated with Coca-Cola (experimental groups) and seven with water (control group). The fluids were applied for 1, 2, 3 h and overnight (15 h), washed off with a few drops of water and the moist enamel indentation hardness tested after each interval. With Coca-Cola treatment, the mean enamel hardness was 92.6% (s.d. = 7.9) of the original baseline hardness after 1 h, 93.25% (s.d. = 10.15) after 2 h, 85.7% (s.d. = 12.03) after 3 h and 80.3% after 15 h. The mean indentation hardness of control specimens treated with water was 108.7% (s.d. = 16.09) of the original hardness after 1 h, 99.09% (s.d. = 18.98) after 2 h, 98.97% (s.d. =11.24) after 3 h and 98.42% (s.d. = 22.78) after 15 h. In a separate experiment, the hardness of 9 enamel specimens was tested, as previously described, before and after treatment with Coca-Cola overnight and again after application of artificial saliva for 3 min. Coca-Cola reduced the mean indentation hardness of enamel in the teeth, but the hardness was partially restored with artificial saliva (Salivart) and increased by 18% from the demineralized enamel hardness.

  11. Colonic obstruction secondary to sigmoid fecaloma endoscopically resolved with Coca-Cola®

    Directory of Open Access Journals (Sweden)

    Guillermo Ontanilla-Clavijo

    Full Text Available Background: Colonic obstruction is a relatively common condition in emergency care, with a mortality rate of up to 20%. In 90% of cases it results from colonic or rectal adenocarcinoma, volvulus, or stenosis secondary to diverticular disease. When fecal impaction is the underlying cause, the condition is usually managed conservatively, but may on occasion become complicated and even require surgical intervention. Based on the proven efficacy of Coca-Cola® to dissolve gastric phytobezoars, we report a case of colonic obstruction secondary to sigmoid fecaloma. Case report: A 58 years old woman arrived at the Emergency Room (ER with persistent constipation for the last six days. An abdominal CT scan showed a large fecal mass at the sigmoid colon with retrograde dilated colonic loops. Cleansing enemas and oral lactulose were administered, which failed to resolve the clinical presentation, so we then proceeded to inject Coca-Cola® within the fecaloma using a sclerosing needle, and then washed the fecaloma surface also with Coca-Cola®. After a few minutes we started to fragment the fecalith, the consistency of which had been notably decreased. Discussion: The use of Coca-Cola® for gastric washes in the management of phytobezoars is well established. Since fecaliths are partly composed of these same substances than phytobezoars, the use of Coca-Cola® might well be warranted against them as in our patient, without surgery. Our case report is the second one published in the literature, in which Coca-Cola® helped solve colonic obstruction secondary to fecaloma.

  12. Cola soft drinks for evaluating the bioaccessibility of uranium in contaminated mine soils.

    2011-08-15

    There is a rising need for scientifically sound and quantitative as well as simple, rapid, cheap and readily available soil testing procedures. The purpose of this study was to explore selected soft drinks (Coca-Cola Classic®, Diet Coke®, Coke Zero®) as indicators of bioaccessible uranium and other trace elements (As, Ce, Cu, La, Mn, Ni, Pb, Th, Y, Zn) in contaminated soils of the Mary Kathleen uranium mine site, Australia. Data of single extraction tests using Coca-Cola Classic®, Diet Coke® and Coke Zero® demonstrate that extractable arsenic, copper, lanthanum, manganese, nickel, yttrium and zinc concentrations correlate significantly with DTPA- and CaCl₂-extractable metals. Moreover, the correlation between DTPA-extractable uranium and that extracted using Coca-Cola Classic® is close to unity (+0.98), with reduced correlations for Diet Coke® (+0.66) and Coke Zero® (+0.55). Also, Coca-Cola Classic® extracts uranium concentrations near identical to DTPA, whereas distinctly higher uranium fractions were extracted using Diet Coke® and Coke Zero®. Results of this study demonstrate that the use of Coca-Cola Classic® in single extraction tests provided an excellent indication of bioaccessible uranium in the analysed soils and of uranium uptake into leaves and stems of the Sodom apple (Calotropis procera). Moreover, the unconventional reagent is superior in terms of availability, costs, preparation and disposal compared to traditional chemicals. Contaminated site assessments and rehabilitation of uranium mine sites require a solid understanding of the chemical speciation of environmentally significant elements for estimating their translocation in soils and plant uptake. Therefore, Cola soft drinks have potential applications in single extraction tests of uranium contaminated soils and may be used for environmental impact assessments of uranium mine sites, nuclear fuel processing plants and waste storage and disposal facilities.

  15. Coca-Cola, caffeine, and mental deficiency: Harry Hollingworth and the Chattanooga trial of 1911.

    Science.gov (United States)

    Benjamin, L T; Rogers, A M; Rosenbaum, A

    1991-01-01

    Harry Hollingworth's 1911 investigation of the behavioral effects of caffeine is one of the earliest examples of psychological research contracted by a large corporation. The research was necessitated by a federal government suit against the Coca-Cola Company for marketing a beverage with a deleterious ingredient, namely, caffeine. Although Hollingworth's research played little role in the outcome of the Coca-Cola trials, it was important as a model of sophistication in experimental design. As such, it set a standard for psychopharmacological research. It also was particularly important in directing Hollingworth toward a life-long career in applied psychology.

    Full Text Available The domestication of plants can be considered as the first genetic manipulation of living organisms and it is associated with the origin of agriculture, and represents the major contribution of biotechnology to the development of mankind. The challenges the agricultural sector faces in the coming decades are population growth and the increasing demand for raw materials for food, feed, as well as the consumer preferences, environmental and legal aspects, and the overall globalisation of the economy. The agricultural biotechnology applications will undoubtedly play a role in meeting these challenges. Spain has competent scientific groups devoted to basic and applied research, with a wide knowledge on agricultural biotechnology. The transfer of the business sector needs to the scientific field, coordinating the R&D companies and research groups from universities and public research organisms is an objective to be attained in the future.La domesticación de plantas, primera manipulación genética de los organismos vivos y origen de la Agricultura, representa la mayor contribución de la biotecnología al desarrollo de la humanidad. Los retos a superar en las próximas décadas para el sector agrario están determinados por el aumento demográfico y la demanda de materias primas para alimentación humana y animal, por las preferencias en el consumo, por aspectos medioambientales y legales, y por la globalización de la economía. Las aplicaciones de la biotecnología agrícola van a jugar un papel incuestionable en el logro de estos retos. Nuestro país posee unos buenos grupos en investigación básica y aplicada, con amplios conocimientos de la agrobiotecnología. El traslado de las necesidades del sector empresarial a la investigación, coordinando los departamentos de I+D+I de las empresas y los grupos de investigación de las universidades y organismos públicos de investigación es una finalidad a conseguir en el futuro.

    2012-03-01

    The aims of the present study were to compare, using multivariate analyses, the degree of similarity of the endoparasite fauna of five fish species belonging to the order Gadiformes: Merluccius gayi, Merluccius australis, Macruronus magellanicus (Gadoidei) and Micromesistius australis and Nezumia pulchella (Macrouroidei), from the southern and central Chilean coast, and to evaluate whether the composition of the endoparasite fauna was determined by phylogenetic or ecological relationships. We employed our database of Merluccius australis, M. magellanicus and Micromesistius australis, which was complemented with published information for M. magellanicus, Merluccius australis, Micromesistius australis, M. gayi and N. pulchella. A higher number of endoparasite species was recorded for Merluccius australis, Micromesistius australis and M. magellanicus, namely Anisakis sp. and Hepatoxylon trichiuri, which is the most prevalent parasite among these hosts. Aporocotyle wilhelmi and Hysterothylacium sp. were detected only in M. gayi, whereas Lepidapedon sp. was found exclusively in N. pulchella. These results suggest that fish ecology rather than host phylogeny was the most important factor for the determination of similarity in parasite composition. This result could be explained by the similar trophic patterns of hosts and by the predominance of generalist larval species among these fish parasite communities.

  1. Does taste matter? How anticipation of cola brands influences gustatory processing in the brain.

    Directory of Open Access Journals (Sweden)

    Simone Kühn

    Full Text Available Brands surround us everywhere in daily life. Here we investigate the influences of brand cues on gustatory processing of the same beverage. Participants were led to believe that the brand that announced the administration of a Cola mixture provided correct information about the drink to come. We found stronger fMRI signal in right mOFC during weak compared to strong brand cues in a contrast of parametric modulation with subjective liking. When directly comparing the two strong brands cues, more activation in the right amygdala was found for Coca Cola cues compared with Pepsi Cola cues. During the taste phase the same beverage elicited stronger activation in left ventral striatum when it was previously announced by a strong compared with a weak brand. This effect was stronger in participants who drink Cola infrequently and might therefore point to a stronger reliance on brand cues in less experienced consumers. The present results reveal strong effects of brand labels on neural responses signalling reward.

    2007-10-01

    We examined the effect of various carbonated beverages, especially Coca-Cola, on the HCO3- secretion in the rat stomach and duodenum. Under urethane anaesthesia, a chambered stomach or a proximal duodenal loop was perfused with saline, and HCO3- secretion was measured at pH 7.0 using a pH-stat method and by adding 2 mM HCl. The amount of CO2 contained in these beverages was about 4-7 g/mL. Coca-Cola topically applied to the mucosa for 10 min significantly increased the HCO3- secretion in both the stomach and the duodenum. The HCO3- response in the duodenum was totally abolished by indomethacin and also partially inhibited by acetazolamide, an inhibitor of carbonic anhydrase. Likewise, the response in the stomach was also markedly inhibited by either acetazolamide or indomethacin. The mucosal application of Coca-Cola increased the PGE2 contents in both the stomach and the duodenum. Other carbonated beverages, such as sparkling water, Fanta Grape or cider, also increased the HCO3- secretion in these tissues. These results suggest that Coca-Cola induces HCO3- secretion in both the stomach and the duodenum, and these responses may be attributable to both the intracellular supply of HCO3- generated via carbonic anhydrase, and endogenous PGs, probably related to the acidic pH of the solution.

    Bowen, William H; Lawrence, Ruth A

    2005-10-01

    The purpose of this study was to determine and compare the cariogenicity of various fluids that are frequently fed to infants and toddlers. We chose to examine sucrose, cola drink, honey, human milk, cow milk, and water because some of these have been associated with development of early childhood caries, although direct experimental evidence is lacking. We used our desalivated rat model because the approach mimics the situation found in infants, whereby the flow of saliva is interrupted through mechanical effects of a nipple. The animals received basic nutrition by gavage, and the fluids being tested were available ad libitum. Thus, the only substances that came in contact with teeth were the test fluids. The investigation continued for 14 days. Cola, sucrose, and honey were by far the most cariogenic. In addition, cola and honey induced considerable erosion. Human milk was significantly more cariogenic than cow milk probably because of its lower mineral content and higher level of lactose. Our data show that the use of honey, cola, and sucrose water in nursing bottles should be discouraged. Although human milk is more cariogenic than cow milk, it is no more cariogenic than are common infant formulas. Protracted exposure to human milk or formula through allowing an infant to sleep on the nipple should be discouraged, and the need for oral hygiene after tooth eruption should be emphasized.

    Iron has been suggested to reduce the erosive potential of cola drinks in vitro. The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout period of 7 days. In each phase, they wore palatal devices containing two human enamel and two human dentin blocks. The volunteers immersed the devices for 5 min in 150 mL of cola drink (Coca-ColaTM, pH 2.6), containing ferrous sulfate (10 mmol/L) or not (control), 4 times per day. The effect of ferrous sulfate on the inhibition of erosion was evaluated by profilometry (wear). Data were analyzed by paired t tests (pcola drinks with ferrous sulfate can be a good alternative for the reduction of their erosive potential. Additional studies should be done to test if lower ferrous sulfate concentrations can also have a protective effect as well as the combination of ferrous sulfate with other ions.

    Full Text Available This study was conducted in order to evaluate the effect of cola beverages drinking on atherosclerosisand test the hypothesis whether cola beverages consumption at early life stages might affect the development and progression of atherosclerosis later in life. ApoE-/- C57BL/6J mice (8 week-old were randomized in 3 groups (n = 20 each according to free accessto water (W, sucrose sweetened carbonated cola drink(C or aspartame-acesulfame K sweetened carbonated 'light' cola drink (Lfor the next 8 weeks. Drinking treatment was ended by switching C and L groups to drinking water. Four mice per group and time were sequentially euthanized: before treatment (8 weeks-old, at the end of treatment (16 weeks-old and after treatment discontinuation (20 weeks-old, 24 weeks-old, 30 week-old mice. Aortic roots and livers were harvested, processed for histology and serial cross-sections were stained. Aortic plaque area was analyzed and plaque/media-ratio was calculated. Early consumption of cola drinks accelerated atherosclerotic plaque progression favoring the interaction between macrophages and myofibroblasts, without the participation of either T lymphocytes or proliferative activity. Plaque/media-ratio varied according to drink treatment (F2,54 = 3.433, p<0.04 and mice age (F4,54 = 5.009, p<0.03 and was higher in C and L groups compared with age-matched W group (p<0.05 at 16 weeks and 20 weeks, p<0.01 at 24 weeks and 30 weeks. Natural evolution of atherosclerosis in ApoE-/- mice (W group evidenced atherosclerosis acceleration in parallel with a rapid increase in liver inflammation around the 20 weeks of age. Cola drinking within the 8-16 weeks of age accelerated atherosclerosis progression in ApoE-/- mice favoring aortic plaque enlargement (inward remodeling over media thinning all over the study time. Data suggest that cola drinking at early life stages may predispose to atherosclerosis progression later in life in ApoE-/- mice.

O objetivo deste trabalho foi caracterizar os acidentes envolvendo tratores agrícolas ocorridos na região da Depressão Central do Rio Grande do Sul e, a partir disto, delinear estratégias eficientes na sua prevenção. Para o levantamento dos dados, foi aplicado um questionário aos operadores de tratores agrícolas da região da Depressão Central do Rio Grande do Sul. Os dados demonstraram que 39% dos trabalhadores rurais entrevistados já sofreram algum tipo de acidente de trabalho com tratores agrícolas. Dentre os tipos de acidentes com tratores agrícolas detectados na pesquisa, destacam-se o capotamento, que correspondeu a 51,71% do total de acidentes graves, e os escorregões, que corresponderam a 40,82% dos acidentes leves. As principais causas dos acidentes relatados foram a falta de conhecimento a respeito das medidas de segurança na operação de tratores (32,77%, a falta de atenção (32,22% para a tarefa executada e o equipamento inadequado (22,22%. Os acidentes graves tiveram causas diferentes comparativamente aos leves. Operadores sem treinamento adequado, a não observação de regras básicas de segurança e a longa jornada de trabalho são tendências observadas neste trabalho que ampliam os riscos de ocorrência de acidentes.

    Full Text Available O objetivo desse artigo é verificar se o trabalho infantil no setor agrícola produz impacto negativo sobre a saúde. Para a análise foram utilizadas as PNADs (Pesquisas Nacionais por Amostra de Domicílios de 1998 e 2003, que trazem suplemento especial sobre saúde, empregando a técnica econométrica de pseudo-painel. Assim, foram consideradas as crianças de 5 a 15 anos em 1998 e de 10 a 20 anos em 2003. Os resultados mostram que, para os indivíduos economicamente ativos, a atividade no setor agrícola e o trabalho de risco no setor agrícola não diferem dos outros setores, ou seja, trabalhar no setor agrícola não impõe um maior desgaste à saúde em relação aos outros setores da economia. Se considerados todos os indivíduos economicamente ativos, os resultados mostram que o trabalho agrícola não afeta a saúde e que o trabalho não-agrícola tem impacto negativo. Dessa forma, acredita-se que a atuação do governo deve ser setorial, visando uma melhoria no acesso ao sistema de saúde, bem como aos medicamentos, e a promoção da educação materna com relação à saúde.The aim of this dissertation is to identify the causal relation between rural child labour and health. The analysis utilized the PNAD, a Brazilian household survey, from 1998 and 2003. The econometric modeling was based on the pseudo-panel approach and was considered the children from 5 to 15 years old in 1998 and from 10 to 20 years old in 2003. The results show that work and work in risky jobs in the agricultural sector do not differ from those impacts of other sectors. It was also presented, for all individuals that work in the agricultural sector does not impact the health capital and work in the non rural sector impact negatively the health capital. So, the government intervention in rural areas should be different from the one implemented on the urban area to mitigate the impact of child labour on health and also, the government intervention should be

    We present a general parallelized and easy-to-use code to perform numerical simulations of structure formation using the COLA (COmoving Lagrangian Acceleration) method for cosmological models that exhibit scale-dependent growth at the level of first and second order Lagrangian perturbation theory. For modified gravity theories we also include screening using a fast approximate method that covers all the main examples of screening mechanisms in the literature. We test the code by comparing it to full simulations of two popular modified gravity models, namely f ( R ) gravity and nDGP, and find good agreement in the modified gravity boost-factors relative to ΛCDM even when using a fairly small number of COLA time steps.

    Full Text Available Due to the large consumption of soft drinks in Brazil and worldwide in recent years and considering that some of the components present in their composition pose potential risks to human health, the aim of this study was to evaluate the cytotoxic and mutagenic potential of specific cola and grape-flavored soft drink brands. Bone marrow cells of Wistar rats were initially treated by gavage with one single dose of Cola or Grape soft drink, which was next offered ad libitum (instead of water for 24 hours. A negative control treatment was performed by administering one single dose of water and a positive control administering cyclophosphamide intraperitoneally. Statistical analysis showed that the Cola and Grape soft drinks studied were not cytotoxic. However, the Cola soft drink proved mutagenic in this experiment treatment time. Therefore, this study serves as a warning about the consumption of Cola-flavored soft drink and for the need for further subchronic and chronic studies on soft drinks in order to evaluate the long term mutagenic and cytotoxic effects of these substances.Devido ao grande consumo de refrigerantes no Brasil e no mundo nos últimos anos, e tendo em vista que alguns dos componentes presentes na composição destes possuem potenciais danosos para os organismos, em especial o humano, o objetivo deste trabalho foi avaliar o potencial citotóxico e mutagênico de uma marca de refrigerante sabor Cola e uma de sabor Uva. Foram utilizadas como sistema-teste as células de medula óssea de ratos Wistar, tratados via gavagem com dose única do refrigerante sabor Cola ou Uva e, em seguida, fornecidos ad libitum (no lugar da água, por 24 horas.

  8. The use of Coca-Cola in the management of bolus obstruction in benign oesophageal stricture.

    Science.gov (United States)

    Karanjia, N. D.; Rees, M.

    1993-01-01

    Oesophageal stricture is a complication of oesophageal reflux and may itself be complicated by bolus obstruction. We reviewed the records of patients presenting with dysphagia and who were found to have benign oesophageal strictures. We studied the outcome of bolus obstruction in 13 episodes affecting eight patients. In six episodes Coca-Cola was administered on the day before endoscopy, and in all these patients the bolus had cleared. In seven episodes nothing was administered before endoscopy, and in all seven a bolus was evident at endoscopy. In five of these seven the bolus was removed piecemeal and in each of these instances the endoscope had to be passed between two and five times. In the remaining two instances the procedure was abandoned and the patients returned to the ward for the administration of Coca-Cola. At subsequent endoscopy these patients were found to be clear of any bolus. These results suggest that the administration of Coca-Cola (or other aerated drinks) may clear a bolus in the acutely obstructed oesophagus. PMID:8476194

    2002-01-15

    An epidemic of health complaints occurred in five Belgian schools in June 1999. A qualitative investigation described the scenario. The role of soft drinks was assessed by using a case-control study. Cases were students complaining of headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, or trembling. Controls were students present at school on the day of the outbreak but not taken ill. An analysis was performed separately for school A, where the outbreak started, and was pooled for schools B-E. In school A, the attack rate (13.2%) was higher than in schools B-E (3.6%, relative risk = 3.6, 95% confidence interval (CI): 2.5, 5.3). Exclusive consumption of regular Coca-Cola (school A: odds ratio (OR) = 29.7, 95% CI: 1.32, 663.6; schools B-E: OR = 7.3, 95% CI: 2.9, 18.0) and low mental health score (school A: OR = 16.1, 95% CI: 1.3, 201.9; schools B-E: OR = 3.1, 95% CI: 1.5, 6.6) were independently associated with the illness. In schools B-E, consumption of Fanta, consumption of Coca-Cola light, and female gender were also associated with the illness. It seems reasonable to attribute the first cases of illness in school A to regular Coca-Cola consumption. However, mass sociogenic illness could explain the majority of the other cases.

  12. Science organisations and Coca-Cola's 'war' with the public health community: insights from an internal industry document.

    Science.gov (United States)

    Barlow, Pepita; Serôdio, Paulo; Ruskin, Gary; McKee, Martin; Stuckler, David

    2018-03-14

    Critics have long accused food and beverage companies of trying to exonerate their products from blame for obesity by funding organisations that highlight alternative causes. Yet, conclusions about the intentions of food and beverage companies in funding scientific organisations have been prevented by limited access to industry's internal documents. Here we allow the words of Coca-Cola employees to speak about how the corporation intended to advance its interests by funding the Global Energy Balance Network (GEBN). The documents reveal that Coca-Cola funded and supported the GEBN because it would serve as a 'weapon' to 'change the conversation' about obesity amidst a 'growing war between the public health community and private industry'. Despite its close links to the Coca-Cola company, the GEBN was to be portrayed as an 'honest broker' in this 'war'. The GEBN's message was to be promoted via an extensive advocacy campaign linking researchers, policy-makers, health professionals, journalists and the general public. Ultimately, these activities were intended to advance Coca-Cola's corporate interests: as they note, their purpose was to 'promote practices that are effective in terms of both policy and profit'. Coca-Cola's proposal for establishing the GEBN corroborates concerns about food and beverage corporations' involvement in scientific organisations and their similarities with Big Tobacco. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available The agricultural and textile sectors, have been the greaters targets of the developed countries protectionism, that possess in common the fact that the amount of man-power used is sufficiently great, it means variation of the products final cost. Therefore, it is not difficult to understand why the most underdeveloped countries are more competitive in the dispute of the world-wide market’s control in these sectors. Thus the importance of the OMC elapses, in the search for the effectiveness of international trade regulation of agricultural goods is an activity that interests the developing countries, what is particularly applicable to Brazil, where the agricultural products answers almost for one third of the exportations.Los sectores agrícolas y textil, han sido los mayores objetivos del proteccionismo de los países desarrollados, que poseen en común la cantidad de mano-de-obra usado y esta energía es suficientemente grande y significa variación del costo final del producto. Por tanto, no es difícil comprender porque cuanto más subdesarrollados los países, más serán competitivos y amenazadores para el conflicto sobre el control del mercado mundial en estos sectores. Así la importancia del OMC transcurre, en la búsqueda para la eficacia de la regulación del comercio internacional de mercancías agrícolas es una, actividad que interesa a los países en vías de desarrollo en su totalidad, lo que es particularmente aplicable al Brasil, donde los productos agrícolas casi contestan para un tercio de las exportaciones.Os setores agrícola e têxtil, têm sido os maiores alvos do protecionismo dos países desenvolvidos, que possuem em comum o fato de que a quantidade de mão-de-obra utilizada é bastante grande o que significa margem de variação do custo final do produto.

    Chin, T W; Loeb, M; Fong, I W

    1995-08-01

    Absorption of ketoconazole is impaired in patients with achlorhydria. The purpose of this study was to determine the effectiveness of a palatable acidic beverage (Coca-Cola Classic, pH 2.5) in improving the absorption of ketoconazole in the presence of drug-induced achlorhydria. A prospective, randomized, three-way crossover design with a 1-week wash-out period between each treatment was employed. Nine healthy nonsmoking, nonobese volunteers between 22 and 41 years old were studied. Each subject was randomized to receive three treatments: (A) ketoconazole 200-mg tablet with water (control), (B) omeprazole (60 mg) followed by ketoconazole (200 mg) taken with water, and (C) omeprazole (60 mg) followed by ketoconazole (200 mg) taken with 240 ml of Coca-Cola Classic. The pH values of gastric aspirates were checked after omeprazole was administered to confirm attainment of a pH of > 6. Multiple serum samples were obtained for measurements of ketoconazole concentrations by high-pressure liquid chromatography. The mean area under the ketoconazole concentration-time curve from zero to infinity for the control treatment (17.9 +/- 13.1 mg.h/liter) was significantly greater than that for treatment B (3.5 +/- 5.1 mg.h/liter; 16.6% +/- 15.0% of control). The mean peak concentration was highest for the control treatment (4.1 +/- 1.9 micrograms/ml), for which the mean peak concentration showed a significant increase over that for treatment B. The absorption of ketoconazole was reduced in the presence of omeprazole-induced achlorhydria. However, drug absorption was significantly increased, to approximately 65% of the mean for the control treatment, when the drug was taken with an acidic beverage, such as Coca-Cola.

    Full Text Available El presente artículo examina las instalaciones y el equipamiento de los establecimientos vitivinícolas del Reino de Chile en el siglo XVIII. El tema es relevante porque en ese momento, Chile era el principal polo vitivinícola de América y ejercía un liderazgo en la región. Se estudian las distintas formas de lagares, tanto los de cuero como los de adobe, cal y ladrillo; también se indaga en la evolución de la vasija vinaria, de la greda la madera. Los hornos botijeros ocuparon un lugar importante por su aporte a la fabricación de tinajas y botijas. Estos recipientes fueron como un icono característico de la viticultura del sur de América (en México la vasija no era de greda sino de madera, aún al comienzo de la industria vitivinícola. Posteriormente, a partir de la mitad de la centuria, comenzó la incorporación de vasija de madera (pipas y barriles en Chile. Durante cincuenta años éstas convivieron con los recipientes de greda, hasta comenzar a sustituirlos progresivamente en el siglo XIX. Este equipamiento hizo posible el desarrollo de una de las principales industrias que hubo en América española durante la época colonial y que, actualmente, sigue siendo la principal industria de Chile.

    Full Text Available Las actividades agrícolas pueden tener impactos negativos sobre el ambiente, con efectos dentro y fuera de los predios. El presente artículo pretende contribuir al avance de la agricultura sostenible con énfasis en países en vías de desarrollo. Se revisan y analizan los conceptos de sostenibilidad y agricultura sostenible, incluyendo los diferentes puntos de vista en el debate sobre sostenibilidad'. El artículo examina los impactos ambientales debidos a las actividades agrícolas, destacando la importancia de fortalecer la investigación, con publicación de resultados, sobre la relación agricultura y medio ambiente. La complejidad de los factores que determinan la sostenibilidad agrícola exige una concepción de sistemas, integradora, participativa y holística. El uso de indicadores tiene un gran potencial en la evaluación de la sostenibilidad de sistemas productivos. La práctica de agricultura sostenible requiere tener en cuenta las condiciones ambientales, sociales y económicas en las cuales
    se desenvuelve la agricultura.Farming activities have the potential to affect the farming system itself and the offfarm environment. This paper attempts to contribute to the development of sustainable agriculture with emphasis in developing countries. The concepts of sustainability and sustainable agriculture are reviewed and discussed, including the different viewpoints in the sustainability debate. Environmental impacts due to farming activities are examined emphasising the need of promoting further research and publication of findings on the links between environment and agriculture. The complexity of the factors that determine farming sustainability requires
    a systematic, holistic, participative and integrated approach. Indicators are likely to contribute to the development of sustainable farming systems. Understanding environmental, social and economic circumstances is required to promote sustainability.

    Full Text Available El desarrollo sostenible se fundamenta en principios éticos, como el respeto y armonía con la naturaleza; valores políticos, como la democracia participativa y equidad social; y normas morales, como racionalidad ambiental. El desarrollo sostenible es igualitario, descentralizado y autogestionario, capaz de satisfacer las necesidades básicas de la población, respetando la diversidad cultural y mejorando la calidad de vida. La agricultura y el desarrollo sostenible se refieren a la necesidad de minimizar la degradación de la tierra agrícola, maximizando a su vez la producción. Este considera el conjunto de las actividades agrícolas, como el manejo de suelos y aguas,el manejo de cultivos y la conservación de la biodiversidad; considerando a su vez el suministro de alimentos y materias primas. La sostenibilidad de los sistemas de producción agrícola se refiere a la capacidad del sistema para mantener su productividad a pesar de las perturbaciones económicas y naturales, externas o internas. La sostenibilidad es función de las características naturales del sistema y las presiones e intervenciones que sufre, así como aquellas intervenciones sociales, económicas y técnicas que se hacen para contrarrestar presiones negativas; destacándose la resiliencia del sistema.

    An 82-year-old male presented with a chief complaint of upper abdominal pain. Subsequently, a bezoar and a gastric ulcer were detected by upper gastrointestinal endoscopy. The bezoar was dark green in color and extremely hard, having a major axis of 7 cm. After hospitalization, 500-1000 ml/day of Coca-Cola was orally administered continuously for 3 weeks. Thereafter, the bezoar decreased in size to a major axis of 4 cm and showed a softening trend. Therefore, lithotripsy was thereafter carried out under endoscopy using forceps.

    A bezoar is a mass of indigestible material. Bezoars can present with a gradual onset of non-specific gastrointestinal symptoms including abdominal pain, nausea and vomiting. However, bezoars can result in more serious conditions such as intestinal bleeding or obstruction. Without quick recognition, particularly in susceptible individuals, the diagnosis and treatment can be delayed. Currently resolution is achieved with enzymatic dissolution, endoscopic fragmentation or surgery. We describe, to our knowledge, the first pediatric patient with lymphoma to have had a bezoar treated with Coca-Cola.

    Full Text Available Corporate brand value, a key corporate asset, has traditionally relied on stakeholder interactions, heritage, and corporate identity. In dynamic fast clock-speed industries (information technology and consumer electronics, we note that brand values change dramatically within a few years based on their innovativeness. Using grounded theory approach and multi-case study method we examine how Apple, Samsung, Toyota, and Coca-Cola sustained their most valuable global brands while Kodak and General Motors eroded the same. Certain key dynamic innovative capabilities are identified as best practices. We conclude with implications for managers and future researchers, along with some limitations.

    To assess the impact of prenatal exposure to Maillard reaction products (MRPs) -rich diet and postnatal Coca-Cola consumption on metabolic status of female rats. Diet rich in MRPs and consumption of saccharose/fructose sweetened soft drinks is presumed to impose increased risk of development of cardiometabolic afflictions, such as obesity or insulin resistance. At the first day of pregnancy, 9 female Wistar rats were randomized into two groups, pair-fed either with standard rat chow (MRP-) or MRPs-rich diet (MRP+). Offspring from each group of mothers was divided into two groups and given either water (Cola-) or Coca-Cola (Cola+) for drinking ad libitum for 18 days. Oral glucose tolerance test was performed, and circulating markers of inflammation, oxidative stress, glucose and lipid metabolism were assessed. MRP+ groups had higher weight gain, significantly so in the MRP+/Cola- vs MRP-/Cola-. Both prenatal and postnatal intervention increased carboxymethyllysine levels and semicarbazide-sensitive amine oxidase activity, both significantly higher in MRP+/Cola + than in MRP-/Cola-. Total antioxidant capacity was lower in MRP+ groups, with significant decrease in MRP+/Cola + vs MRP-/Cola+. Rats drinking Coca-Cola had higher insulin, homeostatic model assessment of insulin resistance, heart rate, advanced oxidation of protein products, triacylglycerols, and oxidative stress markers measured as thiobarbituric acid reactive substances compared to rats drinking water, with no visible effect of MRPs-rich diet. Metabolic status of rats was affected both by prenatal and postnatal dietary intervention. Our results suggest that combined effect of prenatal MRPs load and postnatal Coca-Cola drinking may play a role in development of metabolic disorders in later life.

    To examine the effects of cola-flavored beverages and caffeine on growth and metabolism of Streptococcus mutans biofilm. This study was designed to determine if carbonated beverages or caffeine can increase S. mutans growth and biofilm formation and metabolic activity in vitro, potentially leading to increased S. mutans-associated cariogenicity in children that consume them. Six different cola-flavored products, plus pure caffeine, and pure high fructose corn syrup (HFCS), at different concentrations similar to those in the beverages were tested. A 16-hour culture of S. mutans was treated with different dilutions in bacteriological media. To test for the effect on biofilm formation, the biofilm was stained with crystal violet. The absorbance was determined to evaluate biofilm growth. Biofilm metabolic activity was measured based on biofilm having the ability to reduce XTT to a water-soluble orange compound. The inclusion of HFCS in the beverages, as well as pure HFCS, significantly enhanced bacterial biofilm formation and metabolic activity. Pure caffeine and the presence of caffeine in beverages did not significantly increase biofilm formation, but pure caffeine significantly increased metabolism, and Diet Coke had significantly greater metabolic activity than Caffeine-Free Diet Coke. HFCS increases both the biofilm formation and metabolism of S. mutans, and caffeine in some cases increases metabolism of S. mutans.

    Full Text Available Cet article, tel que son nom de Rhétorique du discours iconique de la marque Coca-Cola l’annonce, a comme thème la structure de la rhétorique des publicités de la marque Coca-Cola. Ces dernières sont représentées, de manière conventionnelle, par deux annexes auxquelles se réfère cette analyse. Ce que ce débat, à caractère sémio-rhétorique, se propose en particulier, c’est de mettre en évidence les liens qui s’établissent entre l’énoncé iconique des réclames de la marque Coca-Cola et les éléments rhétoriques de celui-ci. Les deux composantes (iconique et rhétorique sont évaluées de la perspective d’un discours public, d’un message de nature promotionnelle qui caractérise le marché libre. Cette approche se propose de démontrer les particularités de la rhétorique iconique qui, par le phénomène de l’argumentation discursive, poursuit l’acceptation d’une idée en vertu de raisons pragmatiques ou d’intérêts actionnels. La présente analyse a comme but l’identification des composantes de l’iconicité rhétorique et de la spécificité de celle-ci. L’article trace en ce sens les contours d’une stratégie analytique peu commune ; son objectif consiste dans la présentation d’une liaison pouvant être faite entre l’image et les valeurs rhétoriquesde celle-ci. Le thème de l’analyse est basé sur une dimension théorique qui renvoie à la manière dont les publicités Coca-Cola donnent naissance à un discours qui peut être étudié à partir de catégories rhétoriques telles : ethos, mythos, pathos etc. La seconde partie de l’article représente une analyse de la narrativité iconique et met en évidence la caractéristique rhétorique des images de la marque soumise à l’étude.

    Assessed the effect of single dose attack of Coca-Cola on early erosion and surface microhardness of permanent human enamel, in order to provide diet instructions on minimum amount and frequency of carbonated beverage consumption. Eighty enamel slabs were prepared out of 10 extracted human mandibular third molars, and distributed into 8 groups with randomized block design(n=10). Ten generally healthy volunteers with normal saliva secretion wore acrylic palatal appliances containing 2 enamel slabs, with formation of a salivary pellicle 2 h ahead. The volunteers were instructed to drink 100 ml fresh Coca-Cola within 20 s. And then the alterations of the enamel slabs were measured using a Vicker's microhardness tester at 1, 2, 4, 6, 8, 10, 20 and 30 min after the consumption of Coca-Cola. For each volunteer, the experiment was carried out in four days, 2 samples were examined each time. Data were analyzed using Kruskal-Wallis and Wilcoxon tests(α =0.05). Significant decreases in surface microhardness(SMH)were observed in each time point(PCoca-Cola could lead to significant decrease of enamel microhardness and initiate erosion of enamel surface. Enamel surface microhardness decreased to the lowest points at 2-8 min, and began to recover after 10 min. The enamel surface microhardness could not fully recovered to the baseline level in 30 min if no intervention was performed.

    Coca-Cola was invented in May 1886 in Atlanta, Georgia by a pharmacist who, by accident or design, mixed carbonated water with the syrup of sugar, phosphoric acid, caffeine, and other natural flavors to create what is known as "the world's favorite soft drink." Coca-Cola is currently sold in more than 200 countries and in early 2000, the company sold its 10 billionth unit case of Coca-Cola branded products. Given the worldwide consumption of Coca-Cola, a project of experimental bioassays to study its long-term effects when administered as substitute for drinking water on male and female Sprague-Dawley rats was planned and executed. The objective of the project was to study whether and how long-term consumption of Coca-Cola affects the basic tumorigram of test animals. The bioassays were performed on rats beginning at different ages, namely: (a) on males and females exposed since embryonic life or from 7 weeks of age; and (b) on males and females exposed from 30, 39, or 55 weeks of age. Overall, the project included 1999 rats. During the biophase, data were collected on fluid and feed consumption, body weight, and survival. Animals were kept under observation until spontaneous death and underwent complete necropsy. The results indicate: (a) an increase in body weight in all treated animals; (b) a statistically significant increase of the incidence in females, both breeders and offspring, bearing malignant mammary tumors; (c) a statistically significant increase in the incidence of exocrine ademonas of the pancreas in both male and female breeders and offspring; and (d) an increased incidence, albeit not statistically significant, of pancreatic islet cell carcinomas in females, a malignant tumor which occurs very rarely in our historical controls. On the basis of the results of this study, excessive consumption of regular soft-drinks should be generally discouraged, in particular for children and adolescents.

    A novel method for the fabrication of carbon nanodots (CDs) is introduced: extracting CDs from the well-known soft drink Coca Cola via dialysis. The obtained CDs are of good monodispersity with a narrow size distribution (average diameter of 3.0 nm), good biocompatibility, high solubility (about 180 mg ml-1) and stable fluorescence even at a high salt concentration. Furthermore, they are sensitive to the temperature change with a linear relationship between the fluorescence intensity and temperature from 5 °C-95 °C. The CDs have been applied in high stable temperature sensing. This protocol is quite simple, green, cost-effective and technologically simple, which might be used for a range of applications including sensing, catalysts, drug and gene delivery, and so on.

    Rehardening effects by cow's milk and by secreted saliva were investigated, in situ, following softening of human enamel with an acidic beverage (Coca-Cola). Volunteers wearing orthodontic removable appliances participated in the study. The intra-oral test was chosen for measuring microhardness of enamel slabs inserted into the dental appliance. The softening and the rehardening degrees were defined as the alterations between initial- and experimental-microhardness value at the enamel surface. In addition, SEM photos were prepared from the initial and experimental stages. Exposure of enamel slabs to the acidic beverage during 1 hour had a softening effect as expressed by the hardness decrease and visualized by the SEM photo. Rehardening effects following milk or saliva exposures respectively were evident, presumably due to deposited organic and mineral material on the enamel surface.

    Eye injuries and subsequent loss of vision from the glass and caps of exploding pressurized bottled drinks have been well reported, and as a result most developed countries now use mainly plastic bottles. In Nigeria, however, most drinks are still sold in glass bottles and ocular injuries from this source are therefore not uncommon. To retrospectively analyze ocular injuries resulting from exploding glass-bottled Coca-Cola® and propose ways of eliminating such injuries in future. Eye Clinic, University of Port Harcourt Teaching Hospital, Port Harcourt, Nigeria. The medical records of all cases of ocular injury that presented at the Eye Clinic of the University of Port Harcourt Teaching Hospital over a 5-year period (January 2006 to December 2010) were retrieved and relevant data including age, sex, occupation, events surrounding bottle explosion, and type of ocular injury sustained were extracted. A total of 426 cases of ocular injuries was seen during the period under review. There were 335 (78.6%) males and 91 (21.4%) females. Six patients had ocular injury from exploding glass-bottled Coca-Cola®, giving an incidence of 1.4%. The presenting visual acuities (VA) were light perception (2 cases), counting fingers (2 cases), and 1 VA of 6/24 and 1 VA of 6/12. There were 4 (66.7%) cases of corneoscleral laceration with uveal prolapse and 1 case of total hyphema. Because pressurized glass-bottles can explode with normal handling, legislation to ban the use of glass containers for bottling carbonated drinks will go a long way to reducing ocular morbidity from this source. Plastic bottles should be introduced as an alternative.

    Full Text Available Existen bastantes evidencias para vincular la cultura del vino con el entorno y el desarrollo sostenible. En primer lugar, destaca que la cultura del vino es el reflejo del aprovechamiento vitivinícola del medio y, por tanto, refleja su efecto sobre el desarrollo social y económico de las regiones, lo que es plausible a través del devenir histórico de las mismas. Más recientemente, el aprovechamiento de la cultura del vino para su explotación a través de las experiencias enoturísticas, ha supuesto una revalorización de muchos territorios, impulsando el desarrollo social y económico. La cultura del vino no es sólo el eje temático de la actividad enoturística, sino que es su base y pilar esencial, por tanto, se relaciona directamente con la sostenibilidad ambiental, económica y social que subyace tras el enoturismo. Además, es importante tener en cuenta que gran parte de la importancia de la cultura del vino se centra en las señas de entidad asociadas a cada territorio, que aportan características distintivas y singulares, contribuyendo a la sostenibilidad cultural. En España, ACEVIN y el Rutas del Vino de España son claros ejemplos de como la cultura del vino es un motor del desarrollo sostenible de las regiones vitivinícolas.

    Food additives generally used in carbonated drinks, such as 4-methylimidazole (4MI), caffeine (Caf?), citric acid (CA), and aspartame (Apm), were measured by matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) using nanometer-sized particles of iron oxide (Fe 2 O 3 NPs). The quantification of 4MI in Coca Cola (C-cola) was carried out. In order to improve the reproducibility of the peak intensities, Fe 2 O 3 NPs loaded on ZSM5 zeolite were used as the matrix for quantification. By using 2-ethylimidazole (2EI) as the internal standard, the amount of 4MI in C-cola was determined to range from 88 to 65 μg/355 mL. The results agree with the published value (approx. 72 μg/355 mL). It was found that MALDI using Fe 2 O 3 was applicable to the quantification of 4MI in C-cola.

    Verbeke, Wim; Van Kenhove, Patrick

    2002-01-01

    This article focuses on consumer reactions during and after the Coca-Cola crisis of June 1999 in Belgium. The research tests for associations between the personality trait "emotional stability," attitude toward the brand, and self-reported behavior. Cross-sectional data are collected from a sample of Coca-Cola drinkers between 19 and 22 years old. The data are analyzed through the specification and estimation of a structural equation model and ANOVA. A direct and positive effect of attitude toward the brand on the behavioral response is found. No direct effect of emotional stability on behavior is revealed. However, indirect effects of personality mediated by attitude are discovered. Further, emotional stability is found to correlate negatively with importance attached to information during the crisis. Fast and transparent communication with specific attention to lower emotional stability groups, as well as the inclusion of personality and attitude measurements in future health and food safety studies, are recommended.

    2004-11-01

    The interaction of tooth-coloured dental restorative materials (a conventional glass-ionomer, two resin-modified glass-ionomers and two compomers) with acidic beverages has been studied with the aim of investigating how long-term contact affects solution pH and specimen surface hardness. For each material (ChemFil Superior, ChemFlex, Vitremer Core Build-Up/Restorative, Fuji II LC, Dyract AP and F2000) disc-shaped specimens were prepared and stored in sets of six in the following storage media: 0.9% NaCl (control), Coca-Cola, apple juice and orange juice. After time intervals of 1 day, 1 week, 1 month, 3 months, 4 months, 6 months and 1 year, solution pH and Vickers Hardness Number were determined for each individual specimen. Differences were analysed by anova followed by Student-Newman-Keuls post hoc analysis. All materials were found to reduce the pH of the 0.9% NaCl, but to increase the pH of the acidic beverages. The conventional glass-ionomers dissolved completely in apple juice and orange juice, but survived in Coca-Cola, albeit with a significantly reduced hardness after 1 year. The other materials survived in apple juice and orange juice, but showed greater reductions in surface hardness in these beverages than in Coca-Cola. Fruit juices were thus shown to pose a greater erosive threat to tooth coloured materials than Coca-Cola, a finding which is similar to those concerning dentine and enamel towards these drinks.

    Full Text Available La agricultura es el sustento para la alimentación de una población mundial creciente. La agricultura es la cuarta causa de emisiones de GEI, y emite grandes cantidades de los llamados “gases que no son CO2” incluyendo al N2O y el CH4 con un poder de calentamiento 265 y 28 veces, respectivamente, mayor en comparación con el CO2. En México la información de las emisiones de GEI se reporta en diversos foros y desde diferentes perspectivas. En este trabajo se recopiló información de las emisiones de GEI de las Comunicaciones Nacionales y el Primer Informe Bienal, de publicaciones arbitradas por pares y de la literatura gris. Las emisiones del sector agrícola reportadas en las diferentes Comunicaciones presentan inconsistencias debido a factores como falta de información y de acceso a esta en las primeras dos Comunicaciones y a cuestiones de tipo metodológico en las Comunicaciones subsecuentes. De acuerdo con las estimaciones más actuales (Informe Bienal, las actividades agropecuarias son la tercera causa de generación de emisiones de GEI con una contribución del 12% a las emisiones nacionales. Dentro de esta categoría la mayor parte de las emisiones se generan por la fermentación entérica, el manejo del estiércol y por el uso de fertilizantes en los suelos agrícolas. Los principales retos para mejorar las estimaciones y reducir su incertidumbre es la generación de factores de emisión nacionales para lo cual es esencial contar con mayor información de las fuentes clave. En este trabajo se encontró que existe información relevante que sería de utilidad pero se encuentra dispersa por lo que falta síntesis y organización de la información sobre todo de la que se encuentra en la literatura gris.

    Full Text Available The definition of the agriculture sector as a supplier dominated is a very restrictive supposition which implies that the technological changes would be residual. The learning process of the farmer throughout, determines the increase in productivity, and simultaneously the reduction in the cost of production, which all depends on the ability of the producers to recognize the value of new information, as well as the managerial ability to apply technological knowledge. The investments in the managerial capability of the farmers allow taking better advantage of the external knowledge. With the aim of systemizing the chains of the main ideas on agricultural dynamics, one has sought to construct the Evolutionary Model of Learning. Preliminary results showed that innovative producers on average maintain an avant-garde technological stance. The increase in the absorptive capacity serves to conquer gains in production and to make lower costs.A definição do setor agrícola como sendo dominado pelos fornecedores é uma pressuposição muito restritiva, já que define a mudança tecnológica como residual. O processo de aprendizado do agricultor no decorrer do tempo é responsável pelo aumento da produtividade e, paralelamente, pela redução dos custos de produção, dependendo da capacidade do produtor de interpretar e assimilar as novas informações, bem como da habilidade gerencial do uso do conhecimento tecnológico. Os investimentos na capacidade gerencial dos agricultores possibilitam um melhor aproveitamento do conhecimento externo. No intuito de sistematizar o encadeamento das principais ideias da dinâmica agrícola, buscou-se construir o modelo evolucionário de aprendizado. Os resultados preliminares mostraram que os produtores inovadores, em média, mantêm posições de vanguarda tecnológica. O aumento da capacidade de absorção auxilia nos ganhos produtivos e nas quedas dos custos.

    2009-01-01

    Full Text Available Los cambios sustantivos en el sistema agroalimentario mexicano han impulsado a las empresas a aplicar estrategias que les permitan funcionar en un contexto cada vez más competitivo, complejo e incierto. En el ramo avícola, Industrias Bachoco ha logrado posicionarse como líder nacional, a pesar de las presiones de la apertura comercial y de la competencia interna de dos de los mayores consorcios avícolas transnacionales. El presente artículo destaca los resultados obtenidos por esta empresa a partir de su estrategia de desplazamiento por la república mexicana. Desde la perspectiva de la teoría de la localización y de la nueva geografía económica, se plantea la hipótesis de que tal estrategia le ha permitido a Bachoco sumar ventajas comparativas regionales y le ha conferido la capacidad de suministrar una oferta adaptada a las costumbres y tradiciones de cada mercado regional, que no ha sido igualada por ninguna de sus competidoras. Se concluye que la apertura total inminente del mercado avícola mexicano inducirá al consorcio a acelerar su actualización, para estar a tono y competir con las empresas internacionales.

    Full Text Available Frente al actual escenario territorial, donde la ruralidad persiste en todas sus expresiones identitarias, sociales y económicas, el suelo agrícola pierde extensión, en una pugna constante por sobreponerse a la expansión urbana. Las modificaciones estructurales del espacio periurbano en las últimas décadas nos presentan la consolidación de los procesos de crecimiento y transformación urbana desiguales, que bajo el modelo neoliberal imperante y persistente, se hacen cada vez más visibles en las ciudades de rango intermedio. Si bien no tienen la escala metropolitana, adquieren velocidades de crecimiento urbano aún mayores. El presente estudio compara la evolución de indicadores relacionados con el desarrollo urbano del territorio, para analizar las dinámicas de crecimiento y la pérdida de suelo agrícola. Si bien las ciudades de rango intermedio promueven el consumo de suelo urbano, existe una oportunidad de resaltar el valor patrimonial y productivo del suelo agrícola.

  19. Las actividades complementarias de las explotaciones agrícolas peruanas

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available La diversification des sources de revenu des exploitations agricoles est une question cruciale pour le bien être des populations rurales. En effet, toute utilisation supplémentaire du travail en milieu rural pour des activités autres que celles directement liées à l’exploitation agricole peut contribuer à augmenter les revenus, même modestement. Cet article montre que malgré le potentiel que représentent les activités complémentaires des exploitations agricoles tant en termes de création d’emplois que de revenus, elles sont encore un domaine peu compris de l’économie rurale. Cette faiblesse provient à la fois de l’hétérogénéité de ces activités qui est à la source de nombreuses confusions conceptuelles et des lacunes des statistiques nationales disponibles qui n’enregistrent pas ces activités de manière adéquate. En dépit de ces difficultés, cet article tente de donner un aperçu de l’importance et des caractéristiques des activités complémentaires des exploitations agricoles péruviennes. Quatre conclusions principales émergent de l’ensemble des résultats présentés : la sous-estimation indubitable de ces activités donc des revenus qui en découlent la part significative qu’occupe l’agriculture dans l’ensemble des activités complémentaires, la concentration de ces activités dans deux ou trois secteurs, la relative stabilité de leur distribution selon les secteurs dans le temps et dans l’espace, une division du travail assez marquée entre les hommes et les femmes. La diversificación de las fuentes de ingresos de las explotaciones agrícolas es un asunto crucial para el bienestar de las poblaciones rurales. De hecho, en el medio rural, todo trabajo adicional en actividades distintas a las directamente relacionadas con la explotación agrícola puede contribuir al aumento de los ingresos, aun en forma modesta. Este trabajo muestra que, pese a su potencial en términos de generación de empleos e

    Full Text Available The adsorption of methylene blue from aqueous solution onto activated carbon prepared from cola nut shell has been investigated under batch mode. The influence of major parameters governing the efficiency of the process such as, solution pH, sorbent dose, initial concentration, and contact time on the removal process was investigated. The time-dependent experimental studies showed that the adsorption quantity of methylene blue increases with initial concentration and decreasing adsorbent dosage. The equilibrium time of 180 min was observed and maximum adsorption was favoured at pH 3.5. The dye removal using 0.1 g of adsorbent was more than 90%. This dosage (0.1 g was considered as the optimum dosage to remove methylene blue from aqueous solutions. The equilibrium adsorption data were analyzed by the Freundlich, Langmuir adsorption isotherm models. The kinetics of methylene blue solution was discussed by pseudo-first-order, pseudo-second-order, and Elovich models. The adsorption process follows the Elovich rate kinetic model, having a correlation coefficient in the range between 0.9811 and 1.

    2012-08-01

    This 13-month evaluation used five Kenworth T370 hybrid tractors and five Freightliner M2106 standard diesel tractors at a Coca Cola Refreshments facility in Miami, Florida. The primary objective was to evaluate the fuel economy, emissions, and operational field performance of hybrid electric vehicles when compared to similar-use conventional diesel vehicles. A random dispatch system ensures the vehicles are used in a similar manner. GPS logging, fueling, and maintenance records and laboratory dynamometer testing are used to evaluate the performance of these hybrid tractors. Both groups drive similar duty cycles with similar kinetic intensity (0.95 vs. 0.69), average speed (20.6 vs. 24.3 mph), and stops per mile (1.9 vs. 1.5). The study demonstrated the hybrid group had a 13.7% fuel economy improvement over the diesel group. Laboratory fuel economy and field fuel economy study showed similar trends along the range of KI and stops per mile. Hybrid maintenance costs were 51% lower per mile; hybrid fuel costs per mile were 12% less than for the diesels; and hybrid vehicle total cost of operation per mile was 24% less than the cost of operation for the diesel group.

    Advertising language is an important research material of social change, it is picked up conveniently. There is no distortion and glossing over history, it is the most simple and most visual material. For English advertising, it reflects values, aesthetic tastes, lifestyle, cultural traditions in the U.S., Britain and other countries. With their own unique ways of recording social change, English advertising is quietly playing an important role in the social life and the psychology of social culture. As a practical style, the advertising language has its unique characteristics in vocabulary, syntax, rhetoric and other aspects. Leech opened the first systematic study of advertising language. He studied the various features of advertising language from literature perspective. With the emergence of the theories of pragmatics, some Chinese scholars, like Zhao Jing, Huang guowen, also set out to explore the advertising language from different aspects. But few of them devoted themselves to the English advertising of American beverage. This paper sets out to explore the issues from a pragmatics perspective. Based on the characteristics of advertising language of American Coca-Cola and Pepsi, the paper analyzes the inevitable language impact on social functioning and the concept of values between English advertising and the interaction of modem simple life, revealing the failure of English advertising language in cross-cultural exchanges and social pragmatic information.

    Full Text Available DOI: 10.12957/cadest.2014.18277 Diante de um ambiente cada vez mais competitivo, as empresas devem adotar uma linha de trabalho orientada para qualidade. Nos processos produtivos, o monitoramento e controle da variabilidade são fundamentais para a melhoria da qualidade. Com processos sob controle, os produtos apresentam mais qualidade e a linha de produção mais produtividade. Neste contexto, o controle estatístico do processo, através da utilização das cartas de controle, é requisito para as organizações que buscam reduzir a variabilidade dos processos a fim de aumentar a qualidade dos produtos e reduzir seus custos. As cartas de controle univariadas, mais especificamente para variáveis e atributos, monitoram características da qualidade independentes. Embora amplamente utilizadas, em alguns contextos específicos elas falham, sendo mais indicada a utilização de cartas de controle multivariadas, onde as características da qualidade monitoradas são dependentes entre si. Com isso, este artigo tem por objetivo fazer uma revisão bibliográfica sobre as cartas de controle multivariadas e realizar um estudo de caso aplicado no controle estatístico de processo produtivo de vinícolas italianas.Palavras-chave: Controle Estatístico do Processo; Carta de Controle Multivariada; Qualidade do Vinho.

    Full Text Available O Sistema Agroindustrial Citrícola constitui um exemplo muito interessante de interação entre formas de governança. O mesmo produtor coordena suas transações de venda de laranja para os agentes dos canais de comercialização de várias formas, situação que na teoria é chamada de formas plurais ou mix contratual. Nas vendas para os compradores que destinam a fruta para o consumo in natura, ele realiza transações baseadas no mercado spot. Já nas negociações com a indústria de suco, predominam os contratos. O produtor pode, ainda, arrendar parte da capacidade ociosa de uma indústria para processar sua fruta e vender diretamente ao mercado (quase integração ou integrar a venda da fruta in natura, através de barracões (hierarquia. O objetivo principal deste trabalho é identificar os fatores que explicam a decisão do citricultor em vender para diferentes compradores empregando governanças distintas. Uma das conclusões acerca dos determinantes das formas plurais no caso citrícola está relacionada ao fato de existir necessidades específicas por parte dos compradores que pertencem a canais de distribuição distintos, gerando restrições que tornam a decisão por múltiplos canais e formas de governança a única opção para muitos produtores. Porém, a principal conclusão é a de que as transações entre produtores e os canais de distribuição diferem em pelo menos um dos atributos (especificidade de ativos, frequência ou incerteza, o que explica a adoção de formas diferentes de coordenação.The citrus agroindustrial system is a very interesting example of the interaction of different forms of governance. The same producer manages his orange sales to the market agents in different ways: this situation is called plural forms or contractual mix. On sales to purchasers that sell the fruit for in natura consumption, the producer deals in terms of spot market. On the other hand, contracts are predominant in transactions

    Full Text Available O trabalho visa contribuir para o debate sobre desindustrialização no Brasil, atribuída à apreciação cambial que, para vários autores, decorre do aumento das exportações agrícolas. Do emprego do método constant market share sobre informações de comércio exterior da FAO, para o período 1991-2003, chegou-se à conclusão que a exportação agrícola brasileira cresceu mais que o potencial, resultado de aumento expressivo da competitividade. Depois da mudança cambial, em 1999, parte da competitividade foi neutralizada pelo aumento da participação na pauta de produtos com demanda mundial em declínio. Da decomposição do valor exportado prevaleceu o efeito do aumento da quantidade, fato mais evidente depois da mudança cambial, porque o efeito preço foi negativo. Mesmo descontando o efeito da depreciação real do câmbio, a mudança nos preços internacionais foi desfavorável à agricultura brasileira. O efeito flexibilidade da pauta, negativo em todo o período, indica grande participação de produtos em desacordo com a lei geral da oferta, fato mais grave no período recente, quando a maior parte dos produtos com aumento do volume exportado estava com preço em baixa no mercado internacional. O declínio da exportação de manufaturados e o maior crescimento do comércio de produtos básicos indicam tendência à desindustrialização da agricultura.This paper aims to contribute to the Brazilian deindustrialization debate, attributed to exchange appreciation that, for several authors, is the agricultural export increase effect. Constant market share method applied on FAO export data, for the 1991 to 2003 period, indicates that Brazilian agricultural export increased more than the potential rate, due to expressive competitiveness gains. After the exchange regime change, in 1999, the competitiveness increase was partly neutralized by growth share of products whose world demand was in decline. Exports value decomposition showed

Un total de 7 especies pertenecientes a 6 géneros fueron identificadas: Pomacea bridgesii; Helobia sp.; Thiara (Melanoides tuberculata; Melanoides maculata; Physa sp.; Physella venustula y Biomphalaria sp. Melanoides maculata fue recolectada en el río Lluta y clasificada como especie criptogénica. Los moluscos exóticos recolectados podrían tener éxito en su establecimiento si se considera la vulnerabilidad de los hábitats nativos debido al cambio en las condiciones climáticas globales o a las elevaciones térmicas producidas en el sector costero por los fenómenos de El Niño. En este sentido, las especies subtropicales observadas se podrían considerar como no endémicas y vectores potenciales de zoonosis parasitarias. Las principales vías de introducción de moluscos dulceacuícolas exóticos se derivaron del intercambio comercial, por lo cual, y frente a su incremento interregional, se hace necesario recopilar datos ecológicos y taxonómicos adecuados que permitan evaluar el riesgo de su establecimiento, así como servir de base para la aplicación de futuros tratamientos en bioseguridad.The exotic freshwater mollusk species we report here were collected in wetlands, commercial aquariums, or were given to us by government officials who intercepted some exotic species at customs offices.

    Persistent gaps in the availability of essential medicines have slowed the achievement of global health targets. Despite the supply chain knowledge and expertise that ministries of health might glean from other industries, limited empirical research has examined the process of knowledge transfer from other industries into global public health. We examined a partnership designed to improve the availability of medical supplies in Tanzania by transferring knowledge from The Coca-Cola system to Tanzania's Medical Stores Department (MSD). We conducted a process evaluation including in-depth interviews with 70 participants between July 2011 and May 2014, corresponding to each phase of the partnership, with focus on challenges and strategies to address them, as well as benefits perceived by partners. Partners faced challenges in (1) identifying relevant knowledge to transfer, (2) translating operational solutions from Coca-Cola to MSD, and (3) maintaining momentum between project phases. Strategies to respond to these challenges emerged through real-time problem solving and included (1) leveraging the receptivity of MSD leadership, (2) engaging a boundary spanner to identify knowledge to transfer, (3) promoting local recognition of commonalities across industries, (4) engaging external technical experts to manage translation activities, (5) developing tools with visible benefits for MSD, (6) investing in local relationships, and (7) providing time and space for the partnership model to evolve. Benefits of the partnership perceived by MSD staff included enhanced collaboration and communication, more proactive orientations in managing operations, and greater attention to performance management. Benefits perceived by Coca-Cola staff included strengthened knowledge transfer capability and enhanced job satisfaction.

    Full Text Available Persistent gaps in the availability of essential medicines have slowed the achievement of global health targets. Despite the supply chain knowledge and expertise that ministries of health might glean from other industries, limited empirical research has examined the process of knowledge transfer from other industries into global public health. We examined a partnership designed to improve the availability of medical supplies in Tanzania by transferring knowledge from The Coca-Cola system to Tanzania's Medical Stores Department (MSD. We conducted a process evaluation including in-depth interviews with 70 participants between July 2011 and May 2014, corresponding to each phase of the partnership, with focus on challenges and strategies to address them, as well as benefits perceived by partners.

    Full Text Available Objetivo: caracterizar las granjas avícolas y la autosuficiencia de maíz y soya, en Tungurahua-Ecuador. Metodología: se realizaron entrevistas a noventa avicultores seleccionados mediante muestreo no probabilístico; se utilizó estadísticas de producción y exportaciones reportadas por la Asociación de Fabricantes de Balanceados (AFABA y el Ministerio de Agricultura, Ganadería, Acuacultura y Pesca (MAGAP, y se calcularon índices de Tasa Media de Variación Acumulada y autosuficiencia y dependencia alimentaria. Resultados: en Tungurahua el 78% de avicultores se dedican a la crianza de aves de postura y el 62% tienen instalaciones semiautomatizadas. El 100% de maíz y soya utilizado por la avicultura de Tungurahua, procede de otras provincias e importaciones internacionales. Entre el 2007 y 2016, el maíz registró un índice de autosuficiencia promedio anual de 0.9, mientras que la soya registró 0.08. Limitaciones: la información estadística de producción nacional e importaciones de granos se encontró dispersa. Conclusiones: los resultados indican la presencia de diversos tipos de sistemas de producción avícola. Éstos, según el nivel tecnológico, van desde los artesanales hasta los automatizados. Así mismo, la producción nacional alcanza a cubrir con dificultad la demanda nacional del sector avícola, no así la soya nacional que cubre una mínima parte. Con base en éstos resultados se sugiere mantener la política de sustitución de importaciones de maíz amarillo y ampliar a la soya.

    Full Text Available La estructura económica del Ecuador se ha basado, tradicionalmente, en el sector agrícola, el cual enfrenta un panorama económico mundial desalentador. El actual, pero bajo, precio del petróleo, podría incentivar a los importadores de materias primas, pero a la vez complicaría la situación de los exportadores de productos agrícolas, especialmente en economías, como la ecuatoriana, que no cuentan con estrategias de mejora de los niveles de productividad ante el régimen de tipo de cambio flexible de las economías vecinas y de aquellas que demandan bienes nacionales, es decir, que no pueden devaluar la moneda, para compensar el impacto de las pérdidas en los términos de intercambio de la demanda, que genera el abaratamiento del petróleo. Por otra parte, la tasa de crecimiento de la economía ecuatoriana ha tenido que ser replanteada ante los cambios en el contexto mundial, lo cual puede significar, un retroceso en cuanto a la planeación estatal y la determinación del Presupuesto General del Estado para el 2016. En este escenario, el sector agrícola de Ecuador, se ve abocado a contribuir con un porcentaje –cada vez mayor– a la composición del Producto Interno Bruto, sin contar con incentivos ni mejoras dirigidas precisamente a impulsar este sector.

    Full Text Available Los seguros agrícolas basados en índices climáticos son instrumentos financieros novedosos para la gestión de riesgos de agricultores. A diferencia de los seguros tradicionales, éstos pueden mitigar e incluso anular el riesgo moral y la selección adversa, permitiendo abaratar sus primas. Esta característica hace de este tipo de seguros un mecanismo atractivo para economías en vías de desarrollo con gran parte de población rural sumida en severas condiciones de precariedad y, simultáneamente, se promueve el desarrollo de un mercado de seguros agrícolas. Este tipo de seguros no es aún empleado en Bolivia, pero su promoción por parte del aparato público tiene gran potencial de coadyuvar a la seguridad alimentaria y promover el desarrollo económico. El documento presenta algunas experiencias exitosas en el desarrollo de seguros basados en índices climáticos a nivel mundial y analiza el estado actual de desarrollo de este mercado en Bolivia. Se revisan en detalle los fundamentos técnicos de la creación de este tipo de seguros, a partir de los cuales, se presentan propuestas de esquemas paramétricos de seguros agrícolas basados en índices climáticos para la protección de cultivos de trigo y papa, ambos de ciclo intermedio, en el municipio de Anzaldo (sur-oeste de Cochabamba.

    2010-12-01

    Full Text Available Este artículo presenta algunas metodologías para cuantificar riesgo cuando la distribución de pérdidas presenta eventos extremos, debido a que los activos financieros generalmente presentan alta curtosis. De esta manera, el principal concepto utilizado en el documento es el valor en riesgo (VaR, por sus siglas en inglés, medida introducida por J. P. Morgan en 1995. Desde el punto de vista estadístico, VaR es un cuantil de una función de distribución; sin embargo, su valor dependerá de la forma de la distribución que se utilice para ajustar los datos de pérdida. Por tal razón, al estimar de manera confiable el parámetro de forma de la distribución de pérdidas, se obtiene un estimador confiable de medida de riesgo. La teoría del valor extremo (EVT, por sus siglas en inglés es una técnica estadística que ha sido empleada para tal fin. En este documento se utiliza la metodología de EVT, denominada picos sobre el umbral (POT, por sus siglas en inglés, en el cual, se estima el parámetro de forma de la distribución de excesos mediante máxima verosimilitud. Este método de estimación se revisa brevemente en el documento junto con el método de mínimos cuadrados ponderados. Este último se utiliza para cuantificar el estimador de Hill y con este valor se calcula el VaR para distribuciones con colas pesadas. Finalmente, se comparan las metodologías propuestas en el artículo para cuantificar VaR con otras dos metodologías que son simulación histórica y bajo el supuesto de normalidad mediante pruebas de desempeño a dos casos

En el sureste de Asia, este padecimiento tiene una importancia relativa; en México, se le considera un problema de salud pública emergente desde 1970, cuando fueron registrados los primeros casos. Hasta la fecha, no se han establecido con precisión los caracteres morfométricos para diferenciar las L3A de las tres especies del género distribuidas en este país. Recientemente, se registraron larvas del parásito en peces dulceacuícolas de los Pantanos de Centla, Tabasco, sin definir su identidad específica. El análisis de cuatro especies de peces de la misma localidad reveló que tres de ellos: Petenia splendida (n=58, Cichlasoma managuense (n=35 y Gobiomorus dormitor (n=9, resultaron positivas a la infección por Gnathostoma binucleatum. La identificación del parásito se obtuvo comparando la secuencia del espaciador interno 2 (ITS2 del ADN ribosomal del material de Tabasco, con secuencias disponibles en Genbank.

    Full Text Available This article analyses how the topics linked to water management have changed in social perception and political agenda in Spain. From a hydraulic and agricultural-oriented logic it has shifted toward other more integral and multifunctional one, where the Ministry of Environment is the most relevant player. In such a social and political context, the new orientations of rural development policies are analysed, particularly in relation to the sustainable management of water resources in farming sector and their implications on territory. The authors propose a typology of irrigable areas in Spain, and analyse the process of implementation of the new European Regulation on Rural Development (Reg. 1690/2005. The conclusion is that this new policy could be a useful tool to promote the environmental sustainability of these areas only if there was a good coordination between agricultural and environmental departments at the regional level.En este artículo se analiza la percepción social y política de los temas relacionados con la gestión del agua en España, mostrando cómo se ha pasado de una lógica hidráulica y sectorial (agraria, canalizada a través de los ministerios de Obras Públicas y Agricultura, a otra integral y multifuncional, en la que se valoran sus implicaciones territoriales y en la que asume protagonismo el ministerio de Medio Ambiente. En ese contexto, se analizan las nuevas orientaciones de las políticas de desarrollo rural, especialmente en lo relacionado con la gestión sostenible de los recursos hídricos en la agricultura y sus efectos sobre el territorio. La diversidad del regadío agrícola en España es analizada por los autores, proponiendo una tipología de zonas regables con problemas de eficiencia, y valorando en qué medida las acciones contempladas en el nuevo Reglamento europeo de Desarrollo Rural (FEADER pueden ser un instrumento útil para avanzar en la sostenibilidad ambiental de dichas áreas.

    Full Text Available The aim of this work was to assess the biological and food safety of two different beverages: Classic Coca Cola™ (CCC and Caffeine-Free Coca Cola (CFCC. To this end, we determined the genotoxicological and biological effects of different doses of lyophilised CCC and CFCC and Caffeine (CAF, the main distinctive constituent. Their toxic/antitoxic, genotoxic/antigenotoxic, and chronic toxicity (lifespan assay effects were determined in vivo using the Drosophila model. Their cytotoxic activities were determined using the HL-60 in vitro cancer model. In addition, clastogenic DNA toxicity was measured using internucleosomal fragmentation and SCGE assays. Their epigenetic effects were assessed on the HL-60 methylation status using some repetitive elements. The experimental results showed a slight chemopreventive effect of the two cola beverages against HL-60 leukaemia cells, probably mediated by nonapoptotic mechanisms. Finally, CCC and CAF induced a global genome hypomethylation evaluated in LINE-1 and Alu M1 repetitive elements. Overall, we demonstrated for the first time the safety of this famous beverage in in vivo and in vitro models.

    To develop evidence-based hypoglycemia treatment protocols in patients receiving total enteral nutrition, this study determined the effect on enteral tube flow of glucose therapy agents: apple juice, orange juice, and cola, and it also examined the effects of tube type and feed type with these glucose therapy agents. For this study, 12 gastrostomy tubes (6 polyethylene and 6 silicone) were set at 50 mL/h. Each feeding set was filled with Isosource HN with fibre or Novasource Renal. Each tube was irrigated with 1 glucose therapy agent, providing approximately 20 g of carbohydrate every 4 h. Flow-rate measurements were collected at 2 h intervals. The results showed that the glucose therapy agent choice affected flow rates: apple juice and cola had higher average flow rates than orange juice (P = 0.01). A significant difference was found between tube type and enteral formula: polyethylene tubes had higher average flow rates than silicone tubes (P orange juice, and thus may be considered as primary treatment options for hypoglycemia in enterally fed patients. Polyethylene tubes and Isosource HN with fibre were less likely to clog than silicone tubes and Novasource Renal.

    Full Text Available “Mecanización agrícola; ¿Deterioro o conservación del suelo?” trata sobre el mito de que la mecanización o preparación de los suelos, en forma mecánica, es el detonante del deterioro de los suelos por erosión sobre todo por erosión hídrica y en menor grado por erosión eólica. La erosión de los suelos puede ser de poca o de gran magnitud, dependiendo de cuatro factores, los cuales se analizan como errores que se cometen en el momento de preparar los suelos. Estos errores son, en realidad, los causantes del deterioro de los suelos por erosión y no la mecanización, ya que esta, bien planificada y aplicada, puede incluso servir para la conservaciónde los suelos y el medio ambiente. También se describen los implementos agrícolas que pueden usarse para reducir la erosión de los suelos, citando su forma de trabajo y algunas de las ventajas del uso de esos implementos.

Os operadores de tratores agrícolas foram medidos por meio de um painel constituído por duas chapas metálicas, permanecendo durante as medições em pé, eretos, com o mínimo de roupa possível e em contato com o painel. As variáveis medidas foram as seguintes: altura do corpo; altura ao nível dos olhos; altura ao nível dos olhos sentado; altura do cotovelo; alcance do braço; alcance da mão; distância pé-patela; apoio do assento. Os dados obtidos demonstram que há diferenças entre o biótipo do operador utilizado pela indústria de tratores agrícolas e o do operador da região, de forma que este último apresentou, para todas as medidas, à exceção do apoio do assento, uma média maior. Observa-se também que, para cada medida, os limites inferior e superior do intervalo onde se encontram 90% dos operadores avaliados foram, respectivamente, menores e maiores que o padrão utilizado pela indústria, caracterizando uma maior variação. Levando-se em consideração as diferenças existentes entre o perfil antropométrico dos operadores de tratores agrícolas da Depressão Central do Rio Grande do Sul e os parâmetros utilizados pela indústria, pode-se confirmar a hipótese de que os tratores agrícolas que se encontram atualmente em comercialização no Brasil podem não oferecer o conforto necessário ao operador desta região .The objective of this work was to evaluate the anthropometric measures of the agricultural tractor operators of the Central Region of Rio Grande do Sul State.

Tendo em vista a necessidade de se aumentar a eficiência energética na agricultura, alguns fabricantes disponibilizam para os agricultores uma configuração de TDP que proporciona o acionamento dessas máquinas a um regime de rotação menor do motor do trator. Assim, a rotação da TDP é mantida podendo-se obter uma redução do consumo de combustível. Este trabalho objetivou quantificar o consumo de combustível de um trator agrícola, operando com duas configurações de TDP (normal e econômica em duas áreas agrícolas de relevo distinto. Como resultado, evidencia-se que, com a utilização da TDP econômica, tanto o consumo horário quanto o consumo operacional de combustível, em ambas as áreas trabalhadas, foi menor quando comparado à TDP normal.

    Full Text Available Para proponer estrategias de educación y comunicación sobre plaguicidas en las comunidades agrícolas de Sonora, se requiere situar la problemática de la exposición a plaguicidas en el contexto socio-cultural y ambiental de las comunidades afectadas, tomando en cuenta los factores que contribuyen al mayor riesgo de exposición de los trabajadores agrícolas y de sus familias. Este estudio examina los factores poblacionales, educacionales, culturales y de trabajo de habitantes y trabajadores agrícolas de dichas comunidades, así como las limitaciones de infraestructura comunitaria y de condiciones de vivienda en relación al riesgo de contaminación por plaguicidas. Sobre la base de este análisis se proponen posibles alternativas educacionales orientadas a mitigar tal riesgo en el contexto socio-cultural de dichas comunidades. Método De los estudios reportados sobre la presencia de residuos de plaguicidas en productos agrícolas y acuícolas, en suelos, agua, medio ambiente y en líquidos corporales de niños y adultos de Sonora, se puede concluir que tanto los trabajadores agrícolas como la población que reside cerca de las zonas agrícolas, están sujetos a un mayor riesgo de contaminación por plaguicidas. Para la realización del presente estudio se seleccionaron cinco comunidades localizadas en los valles agrícolas más productivos de Sonora, en las cuales se han llevado a cabo investigaciones relacionadas con plaguicidas. Básicamente, se analizó la información obtenida de encuestas aplicadas a residentes y trabajadores agrícolas de dichas comunidades, para explorar su conocimiento sobre uso y manejo de plaguicidas, percepción del riesgo que tales sustancias representan y las prácticas de protección personal que llevan a cabo para la prevención de dichos riesgos (en el hogar y trabajo. También se describe la infraestructura de los poblados y las viviendas de sus habitantes en relación al potencial de riesgo de contaminaci

    Full Text Available La diversidad geológica y climática de Chile continental permite la diferenciación de una gran variedad de ecosistemas terrestres y acuáticos. La evidencia de los actuales patrones de distribución de especies dulceacuícolas sugiere en gran medida una relación con las glaciaciones del Pleistoceno y algunos eventos tectónicos postglaciales que afectaron la hidrografía del país. Las especies de moluscos dulceacuícolas en Chile, a diferencia de las especies marinas, han sido escasamente valoradas, a pesar del papel que cumple un importante número de ellas en los ecosistemas. Actualmente no existen estudios biogeográficos que permitan establecer patrones distribucionales y los procesos que los condicionaron. Un análisis de parsimonia de endemismos (PAE y de riqueza de cinco zonas hidrográficas, basado en 75 especies de moluscos dulceacuícolas, sugiere la existencia de tres áreas biogeográficas: Norte (entre las latitudes 17°-33° S, Centro-Sur (33°-44° S y Sur (44°-56° S. La zona hidrográfica V (44°-56° S, incluida en el área Sur, posee el mayor porcentaje de endemismo (75 %, a diferencia de la zona hidrográfica III (17°-26° S, incluida en el área Centro-Norte, la cual registró el valor más bajo (42 %.The Chilean geological and climatic diversity allows the differentiation of a great variety of terrestrial and aquatic ecosystems. Evidence provided by distributional patterns of freshwater species suggests a correspondence with Pleistocene glaciations, and some post-glacial tectonic events that affected the hydrography of the country. The species of freshwater Chilean mollusks, unlike the marine species, have been undervalued. Currently there are no biogeographic studies that would allow identifying distribution patterns and the possible processes that shaped them.

Dalla prima notizia relativa ad una proposta di distacco, agli inizi del Novecento, fino al definitivo rifiuto di tale intervento nel 1916, i documenti rinvenuti rivelano alcuni passaggi di un lungo dibattito che vide  opinioni e personalità diverse confrontarsi - e spesso contrapporsi - sul complesso tema del restauro. E’ grazie alla ferma decisione con cui il Ministero della Pubblica Istruzione ne impedì il distacco se, ancora oggi, è possibile apprezzare l’affresco del Filotesio nella sua «sede naturale, nel proprio luogo di origine, dove ess[o] ha[nno] un significato ed un valore assolutamente speciali» (Icilio Bocci.

    Alcohol causes gastroesophageal reflux and mucosal damage in the oesophagus and the stomach. The transmucosal electrical potential difference gives information on gastric mucosal integrity and function, while the validity of oesophageal measurements have been discussed. Baseline oesophageal potential difference measurements were performed three times with an interval of at least one week. We found oesophageal potential difference measurements reliable with an acceptable reproducibility. Oesophageal and gastric potential difference and pH were measured by use of a new microelectrode principle in 10 healthy volunteers following intake of coca-cola, wine and alcohol. Oesophageal and gastric potential difference decreased after intake of 250 ml coca-cola, 250 ml 11 vol% red wine and 60 ml 43 vol% whisky. Gastric potential difference decreased after intake of 250 ml ethanol 11 vol% and 60 ml ethanol 43 vol%. Intake of red wine and whisky resulted in a significant greater gastric potential difference decrease compared to similar concentrations and volumes of ethanol. The time until the potential difference had regained baseline level was longer after intake of red wine compared to coca-cola, whisky and ethanol. Oesophageal pH decreased after intake of coca-cola and red wine, but was unchanged after whisky. Gastric pH was unchanged after intake of all the drinks. In conclusion, the gastric potential difference reduction was not correlated to alcohol concentration. Red wine seems to affect the gastric potential difference more than coca-cola, whisky and ethanol. The observed changes in oesophageal and gastric potential difference might be due to changes in Cl- secretion and/or due to a damaging effect of the additives of the beverages.

Nesta metodologia são abordados todos os tópicos do seu programa. Na abordagem, apesar de ser dirigida aos cursos de Engenharia Agrícola, os temas básicos e aplicações são de interesse de diversos cursos de engenharia e áreas afins. A deficiência de material didático básico para dar suporte a tal disciplina é muito grande, principalmente nos cursos de Engenharia Agrícola, que tratam de um segmento específico relacionado aos Recursos Naturais, o que motivou a realização deste trabalho que, certamente, preencherá a lacuna de um material didático ilustrado e com várias aplicações na Engenharia Agrícola. Nesta pesquisa constatou-se que a utilização da informática nos seus mais diversos modos é uma experiência que, além de estimular e familiarizar o aluno ao uso de novas ferramentas de trabalho, permite formar um engenheiro melhor preparado para as novas necessidades do mercado de trabalho. Verificou-se ainda que a metodologia de ensino desenvolvida nesta pesquisa mostrou-se eficaz no aprendizado do conteúdo da disciplina Sensoriamento Remoto I, ministrada no curso de graduação em Engenharia Agrícola da UFPB.

Methodology/methods: Two brands (CocaCola and Carlsberg which were the official sponsors of a sports event (EURO 2016 were monitored in social media. For this purpose information gathered by socialmention.com and likemore.pl were used. Presentation of the results of the analysis required the use of descriptive statistics as well as the Wilcoxon test and a network graph. Scientific aim: Determination of the scope and nature of the influence of sponsorship of an international sports event on the way a brand is perceived by social media users based on a selected set of data derived from brand monitoring. Findings: In case of Carlsberg the attitude of social media users did not change during EURO 2016, however, majority of their statements was connected with the issues related to this sports event. In case of Coca Cola, the perception of the brand by its clients changed within the studied period of time, however, the issues related to EURO 2016 were only one of many other issues raised by them. Conclusions: Assessment of the influence of brand sponsorship of an event on social media users’ perception faces the following difficulties: scope of monitoring, its efficiency, choice of data set generated by the monitoring tool for the analysis, level of recognition of brands and brand multi-sponsorship (parallel engagement of the brand in many events.

    Full Text Available En este estudio se buscó determinar y analizar el nivel y la estructura del costo y la rentabilidad del proceso de producción de la miel de abeja en los siete principales estados productores de México. Se encontró que la estructura de los costos de producción de la miel se compone mayoritariamente por el costo variable (67.1% cuyos principales rubros son la erogación para el pago de mano de obra y compra de insumos alimenticios, mientras que en el caso de los costos fijos (32.9% el principal valor lo constituyó la depreciación en infraestructura (23.3%. Esta composición del costo total tiene relevancia en la administración de la producción apícola nacional, pues las variaciones en los precios hacia la baja afectan en forma más sensible a los apicultores cuyo costo fijo medio es menor. Por su parte, la principal causa que puede provocar la variación en el nivel de la rentabilidad de las explotaciones apícolas la representa el nivel del ingreso por la venta de miel, el cual determina el precio que se le paga al productor mexicano, que depende del mercado donde realice la transacción. Finalmente, se encontró que la rentabilidad por colmena en México asciende a 158 pesos y a 305.3 pesos por cada mil pesos invertidos en activos fijos, en tanto que la relación beneficio-costo indica una rentabilidad de 38 centavos por cada peso invertido; esta actividad es rentable porque lo invertido supera la recuperación que se obtendría en pagarés de renta fija.

    Thirty-six Sprague Dawley rats, 22 days of age, were divided randomly into three groups of 12 each and housed in a programmable feeder. The three experimental groups received either Coca-Cola (CC), Coca-Cola with calcium lactate (CC-CaL), or distilled water. The programmable feeder was set to deliver 17 equal volumes of fluid per day with each feeding period lasting between 80-90 min. All groups were given Diet MIT 305 in one premeasured amount per 24 hr period (ad libitum). The pH of the CC with calcium lactate was adjusted to match the CC without calcium lactate by the addition of citric and phosphoric acids. The test period lasted five weeks. Each week, the food and fluid consumed and the weight gain were measured. Erosion of the teeth was scored by the method of Restarski et al. (1945). ANOVA indicated that there was a significant difference in the amount of erosion among groups. A Newman-Keuls analysis showed that the mean erosion score of the CC group was significantly greater (P less than 0.05) than that of the CC-CaL and distilled water groups (54.2 +/- 0.12; 0.0275 +/- 0.0123; 0.132 +/- 0.070, respectively). There was no significant difference in erosion between the CC-CaL and distilled water groups. There was no difference in the amount of food and fluid consumed among the group of rats. In conclusion, calcium lactate added to CC resulted in significantly reduced tooth erosion in rats.

    Full Text Available Resumo: O objetivo deste trabalho foi desenvolver um método para identificação e monitoramento, em tempo quase real, de áreas agrícolas cultivadas com lavouras temporárias de verão, com uso de imagens orbitais Modis, no Estado do Rio Grande do Sul. A metodologia foi denominada detecção de áreas agrícolas em tempo quase real (DATQuaR e utiliza imagens do sensor Modis referentes aos índices de vegetação (IVs EVI e NDVI, disponibilizadas em composições de 16 dias. Foram utilizadas quatro métricas para agregar os valores de IVs por pixel, dentro dos períodos bimensais avaliados: média, máximo, mínimo e mediana. Para gerar as imagens (ImDATQuaR, a imagem agregada para o período imediatamente anterior foi subtraída da imagem agregada para o período em monitoramento. Essas imagens foram classificadas por meio de fatiamento e comparadas às classes de referência obtidas pela interpretação visual de pixels aleatorizados em imagens Landsat. Cada ImDATQuaR gerou dois mapas DATQuaR: um com filtragem de moda com janela 3x3 pixels e outro sem filtragem. O melhor mapa DATQuaR é produzido com uso de imagens EVI e filtragem - ao se subtrair a imagem de mínimo valor para o período anterior da imagem de máximo valor para o período monitorado - e atinge concordâncias com a referência superiores a 81%.

    Denture bases may undergo color change over time induced by pigment accumulation within their body; however there is a lack of information regarding the role of yerba mate tea in this process. This work evaluated the effect of five common beverages, including yerba mate tea, on color changes of acrylic denture base resins processed in three different ways. Three different processing techniques were used (P1--microwave irradiation/microwave activated resin; P2--heat polymerization/conventional heat activated resin and P3--microwave irradiation/conventional heat polymerized resin) to make twenty five resin discs each (3.0 mm thick x 20 mm diameter), totaling seventy-five resin discs. The discs made with each technique were randomly divided into five groups (n = 5) and placed in the following solutions: G1-water; G2-cola; G3-coffee; G4-yerba mate tea; G5-red wine, for 30 days at 37 degrees C. The solutions were renewed every 3 days. Color change on the CIE-L*a*b* scale was measured with a Konica-Minolta CR-10 colorimeter and compared with original L* a* and b* values of each specimen prior to immersion. Data were analyzed using 2-way ANOVA, and showed no difference among techniques and significant statistical differences among solutions (p < 0.05). Tukey's post-hoc test showed that the lowest color changes were for water and cola, which were undistinguishable from each other; coffee produced the second lowest color change; yerba mate tea produced second greatest color change, while the greatest color change was produced by red wine. Within the limitations of this study, it was concluded that almost all the solutions used can change color in acrylic resin, especially yerba mate tea, considered distinguishable by professionals, and red wine, considered distinguishable by patients and clinically unacceptable.

  1. Análisis conceptual del uso agrícola del suelo: Su incidencia en la sostenibilidad

    Full Text Available El tema del desarrollo sostenible ha sido muy discutido y analizado en las últimas décadas; no obstante, aún no se ha desarrollado satisfactoriamente; se inició en el año de 1987 con el informe Brundtland denominado Nuestro futuro común, de la Comisión Mundial para el Medio Ambiente. En el informe se puntualiza y se define concretamente al desarrollo sostenible como: “Satisfacer las necesidades del presente sin comprometer la capacidad de satisfacer las futuras generaciones”. En la actualidad, casi todas las personas coinciden con tan importante definición; sin embargo, no se ha plasmado a los niveles que se requiere para deshacer los trances que se exhiben en ese sentido a escala mundial, fruto de los ambiciosos intereses particulares.  El suelo es uno de los recursos que, en condiciones ambientalmente normales, bien puede llenar las expectativas de poder llevar a la praxis tan anhelada descripción, integrando con perspectiva de sistema agrícola los tres elementos claves que la componen: el elemento social, el económico y el ambiental.  El desarrollo de los sistemas agrícolas y sus aplicaciones e implicaciones en el proceso de la sostenibilidad, trae consigo cambios considerables en términos social, económico y ambiental, que, indudablemente, contribuye a tan anhelado proceso, en el sentido de poder lograr un cambio en el entorno común, alcanzando a armonizar la naturaleza, los beneficios económicos y las necesidades de la población.

Além disso, pretendeu-se verificar se as vinícolas fazem uso do isomorfismo em suas respostas às pressões do ambiente institucional para obterem legitimação na comunidade vitivinícola. Para tanto, foram revisados temas relativos à teoria institucional, em suas vertentes respostas estratégicas, pressões ambientais e isomorfismo, bem como se buscaram, em sítios eletrônicos e artigos acadêmicos, etc., pressões oriundas do ambiente institucional que impactem diretamente nas atividades das vinícolas em estudo. Foi realizado um estudo qualitativo, tendo como instrumento para coletar os dados primários, junto a três vinícolas que compunham a amostra, um roteiro de entrevista semiestruturado com três questões abertas. Entre os resultados, verifica-se que todas as vinícolas adotaram respostas estratégicas menos flexíveis face às requisições dos consumidores por práticas ambientalmente corretas.

    Gastric bezoars are concretions of undigested material, and Coca-Cola therapy is an easy, efficacious and safe approach for bezoar treatment. Gastric outlet obstruction due to a migratory gastric bezoar during Coca-Cola therapy is an uncommon presentation and, to the best of our knowledge, no cases have been previously reported. We herein describe one such case with no known predisposing factors that recovered via the endoscopic technique. A thorough literature search was performed, which yielded eight relevant patients from seven publications, all of who developed gastrointestinal obstruction during dissolution treatment and recovered uneventfully after surgical intervention. In conclusion, this potential complication should be kept in mind in the event that alternative treatment is necessary.

    Full Text Available Resumo: O presente artigo analisou o comportamento do preço da terra agrícola nos municípios do Paraná no período de 1999-2011. Partindo da revisão bibliográfica dos principais estudos nacionais sobre o tema, foi possível identificar os determinantes do preço da terra e os métodos utilizados. Neste sentido, optou­-se por estimar um modelo para o preço da terra via painel de dados espaciais. As estimativas indicaram que o valor bruto da produção agropecuária, a valorização patrimonial, o financiamento total à agropecuária, a relação investimento-receita municipal, o percentual da área plantada do município com soja e a incorporação da dependência espacial do preço da terra são variáveis que explicam o preço da terra no estado do Paraná. Estas explicariam 84% dos preços e indicaram que há maior ajuste intrapainel, sendo os efeitos espaciais mais intensos no próprio município e em relação ao todo. Em especial, o modelo proposto avançou em termos estruturais, com a incorporação de variáveis coletadas para todos os 399 municípios do Paraná, e em termos metodológicos, ao estimar via painéis de dados a influência dos efeitos de espacialidade sobre o preço da terra agrícola, destacando a importância da localização e da vizinhança na determinação de tal preço.

    Full Text Available O principal objetivo deste artigo é analisar as implicações das transformações tecnológicas da agricultura paranaense e os impactos ambientais decorrentes dessas mudanças estruturais, elegendo como cenário a região Oeste do Paraná. O modelo agrário tecnológico introduzido na agricultura brasileira desde a década de 1950, e, posteriormente (década de 1970, especificamente no quadro agrícola paranaense, tem como uma de suas características centrais a exclusão dos pequenos produtores, estimulando a produção de cultivos de elevada cotação comercial (commodities, os quais por sua natureza requerem extensas áreas de plantio, em detrimento dos alimentos produzidos pela maioria dos produtores. Cabe destacar que a pressão do setor industrial sobre o setor agrícola, fortalecido após o processo de industrialização e de internacionalização do capital, é significativa. A metodologia empregada envolveu a revisão bibliográfica, relacionando os ciclos econômicos que marcaram a ocupação do território paranaense e a exploração dos recursos naturais, como também a manutenção das áreas de preservação ambiental, mais especificamente o Parque Nacional do Iguaçu, instituído em 1939, como reserva de Proteção Integral. A análise dos resultados permitiu considerar o caráter de dispersão das mudanças tecnológicas na agricultura do Estado do Paraná, entendendo que nem todas as regiões do Estado se tecnificaram e mecanizaram ao mesmo tempo.

    Full Text Available RESUMEN La caracterización de la actual dinámica del Cinturón Hortícola Platense tendría un mejor ajuste si se interpreta desde el enfoque de economías de aglomeración. Así, una actividad que se caracterizó históricamente por su producción atomizada y descentralizada, ahora muestra una concentración espacial y cercana articulación con los eslabones de aprovisionamiento de insumos y comercialización. El objetivo del trabajo es desarrollar la influencia y dependencia de un servicio existente en la zona hortícola platense: las plantineras. Se busca identificar las razones de su surgimiento, su evolución y actual importancia y dependencia. También describir su interrelación con las semilleras y agronomías. Finalmente, se caracteriza el rol de las plantineras en el aglomerado de empresas que conforma la horticultura platense. Se concluye que las plantineras pueden considerarse un caso de economía externa, causa y consecuencia a su vez del incremento de la competitividad en este espacio productivo. ABSTRACT The current dynamics of La Plata’s Horticultural Belt seem to fit better if interpreted from the agglomeration economies perspective. Thus, an activity historically characterized by its fragmented and decentralized production nowadays shows a spatial concentration and close coordination with the links in supply of inputs and marketing. The aim of this work is to develop the influence and dependence on an existing service in La Plata’s horticultural zone: the nursery garden. It seeks to identify the reasons for its emergence, evolution and current importance and dependence. Also to describe their interrelationships with seed companies and agrochemical shops. Finally, the nursery garden role in horticultural agglomerate of La Platais characterized. It is concluded that nursery garden could be considered a case of external economy, cause and consequence of increasing competitiveness in the productive space.

    We report a case of gastric bezoar-induced gastric outlet obstruction that was successfully treated with a combination of endoscopic injection and irrigation with Coca Cola. A 73-year-old diabetic woman had a history of perforated peptic ulcer and had received pyloroplasty more than 20 years previously. She had been ingesting Pho Pu Zi (Cordia dichotoma Forst. f.) as an appetizer for 1 month. She presented with epigastric pain, nausea, and vomiting. Upper gastrointestinal endoscopy, performed at a local hospital, showed 2 gastric bezoars in the stomach, and 1 of them impacted at the pylorus. She was referred to our emergency department for removal of the gastric bezoars that were suspected to be causing gastric outlet obstruction. All attempts at endoscopic removal using a polypectomy snare, biopsy forceps and Dormia basket failed. We then injected Coca Cola directly into the bezoar mass, followed by irrigation with Coca Cola. Follow-up endoscopy was performed the next day, which revealed that the gastric bezoars had dissolved spontaneously.

    Full Text Available Este trabalho analisa a questão do financiamento da produção agrícola sob uma ótica sistêmica, considerando o papel dos agentes privados no fornecimento de crédito rural. Desenvolve-se a idéia de que o volume e o custo de recursos financeiros disponibilizados para a produção agrícola são afetados por "fricções" em diversas transações sequenciais interligando emprestadores e tomadores de crédito. O objetivo do trabalho é analisar as vantagens comparativas dos diversos agentes que atuam no mercado de crédito, enfocando o potencial de cada agente em reduzir as tais fricções. Esta análise comparativa baseia-se na leitura do funcionamento do mercado de crédito agrícola dos Estados Unidos e pode ser aplicada nara o desenvolvimento de novos arranjos contratuais no mercado brasileiro.

Se tomara como horizonte epistemológico las contribuciones de una sociología de las emociones para desentramar los operativos ideológicos que subyacen en el montaje de las distintas instantáneas de consumo en torno a la campaña. Será pertinente para este caso, realizar una genealogía de las interpelaciones a lo sensible que construyó la empresa desde su llegada al país en 1942 y el especial tratamiento que reside en esta última apuesta del monopolio de la bebida al asalto de las experiencias. Por último, siguiendo el dictum benjaminiano, algunas imágenes publicitarias de la campaña que circulan en redes sociales para pensar el escenario mediático que refuerza los procesos de regulación a lo sensible.

    The paper introduces an RO unit (reverse osmotic membrane equipment) for producing water holding for the canned coffee drink processing line introduced to the Ibaraki plant of Tone Coca-Cola Bottling Co. The unit aims at reducing hardness components from city water and producing water holding for the coffee drink processing line. The capacity of the unit is 25m{sup 3}/h and the recovery rate is 80%. The unit is composed of a sand filter, an heat exchanger, a pre-filter, RO modules, a treated water tank, chemicals storage tanks, and an RO cleaning unit, which are all for pretreatment. The treated water, into which chlorine is injected, is sent through the existing activated carbon tower and micro filter to the processing line. The RO unit can remove at the same time ion and trihalomethane, pathogens, organic matters which are substances other than hardness components. The continued water bottling is possible with no need for the usual reproduction process, and the maintenance is easy. Because of the high hardness of the supplied raw water, acid is injected at the primary side of the unit for pH regulation to prevent scale deposition in the RO modules. The quality of the treated water well met the specifications. 2 figs., 2 tabs.

    y en su parte sur vuelve a ser plana. La cría del ganado parece ser la ocupación principal; se concentra en los alrededores de Villavicencio. Se han hecho varios intentos espontáneos para colonizar parte de esta región pero sin resultados definitivos. Al tratar sobre la agricultura de un país se hace necesario tomar en cuenta la distribución de sus recursos humanos. La población de Colombia es de unos 10 habitantes por kilometro cuadrado, pero esta cifra global no da ni siquiera una idea aproximada de cómo está poblado el país, ya que más del 98 por ciento de su población vive en el tercio occidental de la nación aun dentro de esta zona la fluctuación por departamentos es bastante grande. Por otro lado están las zonas agrícolas pues hemos visto distintas clasificaciones del país en zonas fitogeográficas y de elevación. Sin embargo éstas no tienen un valor económico inmediato. Dentro de ellas existen regiones más pequeñas pero más homogéneas en cuanto al clima, régimen de lluvias, suelos y organización que se especializan en la producción de uno o más agrícolas. Estas regiones deberán servir en el futuro como núcleo de los estudios de economía de producción agrícola, por tener todas ellas sistemas de agricultura más o menos conocidos pero cuya verdadera organización económica se desconoce. Como en el país no se han hecho todavía estudios serios de geografía económica y las publicaciones de la Contraloría General de la República en este campo se han limitado a una recopilación de los pocos datos estadísticos que se disponen los departamentos, se dan las siguientes descripciones de las zonas agrícolas para que se tenga una idea aproximada de sus principales características.

    Full Text Available Se analizó el impacto del clima en los problemas de salinidad, drenaje y producción agrícola en el Distrito de Riego 038 río Mayo Sonora el cual presenta afectaciones por sales en 32% de su superficie. Con datos de clima y agronómicos generados entre 1970-2001, se elaboraron modelos de regresión lineal simple para estudiar la relación entre la superficie ensalitrada con la temperatura ambiente, superficie afectada por niveles freáticos superficiales, volumen de riego, salinidad del agua de riego, precipitación pluvial, producción agrícola y productividad del agua. Asimismo, se correlacionó el manto freático con la temperatura, volumen de riego y precipitación pluvial. La producción se correlacionó con la salinidad del suelo, temperatura ambiente, superficie afectada por niveles freáticos superficiales y volumen de riego. Además, por medio de modelos de regresión lineal múltiple se determinaron las relaciones tanto de la superficie ensalitrada como de la producción agrícola, con la temperatura, superficie afectada por niveles freáticos superficiales, volumen de riego, superficie cosechada y precipitación pluvial. Los resultados evidenciaron que el aumento de superficie ensalitrada está relacionado con el incremento de temperatura; mismo que se asoció con la disminución del volumen de cosechas y con el aumento de superficie con niveles freáticos. Se encontró que los volúmenes de riego impactan en el incremento de la superficie agrícola con niveles freáticos someros y con el aumento de superficie ensalitrada. Con el calentamiento global los problemas de salinidad del suelo se incrementaron entre 24.1 y 15.8% en los estratos de suelo a 30 y 60 cm de profundidad, respectivamente. Asimismo, se estimó un crecimiento del 21.9% de superficies con niveles freáticos superficiales. El impacto del calentamiento global en el volumen de producción agrícola se estimó en una reducción del 18.9% del volumen de cosechas.

En el estudio se utilizaron imágenes aéreas correspondientes al proyecto Misión Carta cap - turadas entre febrero y marzo del 2005, lo que permitió identificar la distribución y extensión de los principales cultivos existentes en la GAM. Para identificar estas áreas se utilizó el método del reconocimiento remoto, el cual consiste en conocer la apariencia de un determinado cultivo en imágenes aéreas que permiten ubicar todas las áreas con aspecto similar y así identificar la adecuada diferenciación entre cultivos y usos. La información geográfica fue procesada mediante el programa de cómputo ArgGIS 9.2, el cual per - mitió obtener un mapa base a escala 1:12.500. El mapa con la distribución de las áreas de cultivo, se superpuso con información geográfica que ha sido previamente desarrollada por diferentes instituciones del país, lo que permitió caracterizar la actividad agrícola de la GAM. Los resultados muestran que la actividad agrícola cubre alrede - dor del 24% del área total de la GAM, destacán - dose la producción de hortalizas, café y plantas ornamentales bajo sarán. Las hortalizas tienen la mayor importancia en extensión, ya que abarca el 52% del área agrícola de la GAM, seguidas del café con 44%, mientras que la producción de ornamentales bajo sarán representa solamente cerca del 4%. Al analizar los cambios ocurridos en la actividad agrícola de la GAM en los últimos 28 años, en el caso del café el área de producción disminuyó en 3569 ha, lo cual corresponde al 17% de las 22 545 ha identificadas en 1983.

    AIM: To establish a 'one-stop' dysphagia service in which a consultation, barium swallow and endoscopy can all be performed in the same hospital visit. MATERIALS AND METHODS: In order to allow both barium swallow examination and endoscopy to be performed on the same day, a novel technique for clearing barium from the upper gastrointestinal tract was established. Following the barium swallow examination, patients were given diet cola and metoclopramide syrup. If appropriate, an upper gastrointestinal endoscopy was then performed shortly afterwards. The service was piloted for 6 months in which time 25 patients were investigated in this way. RESULTS: All patients were seen within 2 weeks of referral. The mean time between barium swallow and endoscopy was 3 h 38 min (range, 1 h 50 min to 5 h 20 min). In all 24 patients in whom an endoscopy was performed, barium had been satisfactorily cleared from the oesophagus and stomach. CONCLUSION: This technique allows both barium swallow and upper gastrointestinal endoscopy to be performed on the same day, providing a rapid, safe and accurate diagnosis with minimum patient inconvenience.

    Full Text Available Costa Rica ha incrementado el uso de plaguicidas de mayor toxicidad, debido entre otras cosas al desarrollo de plagas más resistentes y la necesidad que tienen algunos productos agrícolas de exportación de mantener su posición en el mercado internacional. El ser humano al entrar en contacto con los plaguicidas puede experimentar efectos adversos en su salud desde agudos hasta crónicos que se manifiestan en diferentes grados. Para generar indicadores de peligro en salud en algunos cultivos por el uso de estas sustancias, se utilizaron la cantidad de plaguicidas aplicada y su toxicidad. Los datos de uso se recopilan directamente de los productores, a través de un cuestionario, los ingredientes activos identificados se caracterizaron por su toxicidad y se clasificaron por la manifestación de los efectos. Se calculó como indicador la cantidad de plaguicidas aplicada (kg ia/ha/año por las clases de toxicidad consideradas más peligrosas: 1. Efectos de toxicidad aguda en grado de alto a extremo y 2. Tres o más efectos crónicos positivos. Se recomienda vigilar el uso de bromuro de metilo, metam sodio, terbufos, etoprofos, endosulfan, MCPA y carbofuran por toxicidad aguda de alta a extrema y mancozeb, paraquat, diazinon, 2,4-D y carbofuran por efectos crónicos.

    Intraluminal duodenal pH was recorded using a combined miniature electrode and logged digitally every 10 or 20 seconds for five hours (basal/meal/drink) in eight control subjects and 11 patients with duodenal ulcer (five on and off treatment with cimetidine). Over the whole test there were no significant differences in duodenal mean pH or log mean hydrogen ion activity (LMHa) between control subjects and patients with duodenal ulcer, but there were significantly longer periods of duodenal acidification (pH less than 4) and paradoxically more periods of duodenal alkalinisation (pH greater than 6) in the duodenal ulcer group compared with controls. After a meal duodenal mean pH and LMHa fell significantly in both controls and patients with duodenal ulcer, with more periods of duodenal acidification and alkalinisation in the duodenal ulcer group. An exogenous acid load (Coca-Cola) significantly increased the periods of duodenal acidification, and reduced alkalinisation, in both groups. Cimetidine significantly increased mean pH and LMHa and abolished the brief spikes of acidification in four of five patients with duodenal ulcer. Peak acid output (but not basal acid output) was significantly correlated with duodenal mean pH and LMHa but not with the periods of duodenal acidification. Smoking did not affect duodenal pH in either group.

    Full Text Available O desenvolvimento econômico e social de uma região deve estar baseado nos princípios da sustentabilidade ambiental, pois, não sendo assim, corre-se o risco de se deixar para as gerações futuras uma herança de escassez e miséria. Portanto, este trabalho procurou identificar os tipos de produção e manejos dados às áreas agrícolas. Foi realizado com produtores de hortifrutigranjeiros dos municípios de Silveira Martins, Nova Palma e Ivorá, no Rio Grande do Sul, selecionados por sua área territorial encontrar-se inserida nas encostas da Serra Geral, cuja fragilidade ambiental é maior. Foram aplicados questionários do tipo fechado a todos os produtores de hortifrutigranjeiros dos referidos municípios com base em listas fornecidas pelas secretarias de agricultura municipais e Condesus. Concluiu-se que a maioria dos cultivos se dá nas encostas pela própria topografia regional. A maioria dos produtores conduz suas atividades para produção e comércio e são majoritariamente conscientes dos riscos e interessados em projetos que viabilizem a unidade de produção de forma sustentável.

    Full Text Available El objetivo de este artículo es analizar las formas de violencia laboral contra mujeres jornaleras agrícolas en tres comunidades de Sinaloa, Sonora y Baja California, para lo que se utilizó una metodología cualitativa, a través de entrevistas grupales que se les hicieron a ellas. Los resultados señalan que las trabajadoras reconocen la violación a sus derechos laborales, como no contar con servicios médicos para ellas y sus hijos, ni ingresos por faltar al trabajo cuando éstos enferman y menos opciones laborales durante el embarazo. A diario viven el acoso y el hostigamiento ejercido por hombres posicionados en distintas jerarquías laborales, pero no son pasivas ante la violencia, ya que diseñan estrategias de autocuidado. Otras se organizan para brindar asesoría a mujeres sobre sus derechos laborales y las acompañan en los procesos de denuncia y búsqueda de justicia.

    Full Text Available El cultivo y la comercialización de Organismos Agrícolas Modificados Genéticamente (0MG es origen de multitud de importantes polémicas sociales, económicos y ecológicas, en cuya resolución a menudo se reclama la incorporación del principio y de prácticas de precaución. Este artículo introduce y analiza algunas de estas discusiones a partir de la perspectiva aportada por el proyecto europeo Precautionary Expertise for GM Crops (PEG sobre la aplicación de la precaución en el desarrollo y la comercialización de OMG agrícolas. A partir del material recogido en el caso español, los autores argumentan que gran parte de los desacuerdos que surgen de en la interpretación y aplicación de la precaución con relación a los OMG derivan de la adopción de una perspectiva más o menos reduccionista, o más o menos sistémica, tanto en la evaluación y regulación de los riesgos como en la bondad, los costes o los beneficios de su utilización. Por ello es posible detectar analíticamente, paro el caso español, una clara oposición entre aquellas interpretaciones de la precaución caso por caso, de aquellas que sostienen la necesidad de aplicar prácticas de evaluación y de gestión basadas en una precaución sistémica, más cercano a los principios y los postulados políticos de la sostenibilidad.The debate over GMO crops and their commercialisation becomes the source of a large number of conflicts with important social, economic and ecologic consequences the resolution of which often calls for the application of a precautionary approach and of the precautionary principle. This article introduces and analyses such discussions, and does so within the framework provided by the EU project Precautionary Expertise for GM (PEG. Based on first material gathered for the Spanish case study, the authors argue that a large majority of the disagreements around practical application of precaution over agricultural GMO in Spain come from a conception

    Full Text Available La formación de recursos humanos y la generación de conocimientos adaptados a las condiciones de explotación de las diversas produccio-nes regionales en la Argentina ocuparon la atención de los técnicos del Ministerio de Agricultura de la Nación, de las entidades agraristas y de sectores políticos y educativos diversos desde inicios del siglo XX. No escapó a ese interés la preocupación por la mujer y el “hogar agrícola”. En el presente artículo fueron analizadas, en ese contexto, las primeras décadas de la Escuela Granja “Ramón Santamarina” de Tandil, un esta-blecimiento con una rica historia institucional que albergó la primera es-cuela del hogar agrícola del país, transformada pronto en granja-escuela y especializada en industria láctea. El tránsito del “hogar agrícola” a la preparación de maestros queseros -en el marco de la orientación productivista de las escuelas en la pro-puesta educativa del Ministerio-, los sujetos sociales involucrados, la es-pecialización en quesería y sus resultados, son algunas de las cuestiones analizadas. Esto se inserta en el contexto de un proyecto educativo agra-rio pensado no solo como fuente de mano de obra, vinculado a determi-nadas industrias agrarias, sino también –y tal vez más que nada– como irradiador de ese tipo de enseñanzas hacia la comunidad.

    Full Text Available RESUMOA determinação do torque nos rodados motrizes dos tratores agrícolas complementa os ensaios de tração e permite o cálculo da distribuição dos esforços tratórios entre os eixos. O objetivo principal desta pesquisa foi determinar a demanda de torque nos rodados motrizes de um trator com potência do motor de 89 kW, buscando avaliar o torque demandado em função da utilização da tração dianteira assistida (TDA, para distintas marchas e conforme aumento da força de tração. Foram realizados ensaios de tração sobre pista de concreto utilizando-se um torciômetro instalado no eixo traseiro do trator, um carro dinamométrico e instrumentação eletrônica para aquisição de dados. Avaliaram-se a TDA ligada e desligada, quatro marchas (5, 7, 8 e 9 km h-1 e oito cargas na barra de tração (4, 8, 12, 16, 20, 24, 28, 30 kN. Os resultados analisados estatisticamente através de equações de regressão indicaram comportamento similar para todas as marchas sendo que, conforme o aumento da força de tração ocorreu crescimento linear da demanda de torque nos eixos motrizes. Com a TDA ligada nas cargas mais baixas o torque é maior no eixo dianteiro e nas cargas mais altas é maior no eixo traseiro.

    Full Text Available La rana arborícola mexicana Smilisca baudinii, es una especie de rana común en Centroamérica. Sin embargo, la biología y genética de la especie, es pobremente conocida a pesar de su importancia para mantener en equilibrio ecológico las selvas tropicales. Con el propósito de contribuir con el conocimiento biológico de esta especie, establecimos el cariotipo típico en meiosis en especímenes recolectados en Tabasco, México, mediante procedimientos citogenéticos estándares. El estudio, se fundamentó en el análisis de 131 dispersiones cromosómicas en estadio meiótico de dos adultos de la especie (una hembra y un macho. El análisis de las metafases, permitió establecer el número modal haploide de 1n=12 cromosomas bivalentes. La fórmula cromosómica del cariotipo haploide, se integró por 12 cromosomas birrámeos caracterizado por 12 pares de cromosomas bivalentes metacéntricos-submetacéntricos (msm. Los conteos en meiosis, hacen suponer como número diploide de cromosomas a un complemento integrado por 2n=24 cromosomas birrámeos. No fue posible observar presencia de cromosomas sexuales, entre las dispersiones meióticas del espécimen hembra y macho. Los resultados sugieren que la estructura cromosómica de S. baudinii, es compartida ampliamente entre las especies de la familia Hylidae y los cromosomas "B" son estructuras importantes en la diversificación de las especies.

    Full Text Available Este artigo analisa os efeitos dos ganhos de produtividade na agricultura sobre o processo de industrialização e, conseqüentemente, sobre o crescimento de longo prazo da economia. Supõe-se no modelo que a produtividade na agricultura é endógena e que a experiência acumulada na indústria exerça impacto positivo sobre a produtividade agrícola. Uma condição necessária para o declínio do emprego industrial é que, devido à vantagem comparativa na agricultura, a economia do resto do mundo apresente baixa integração agricultura/indústria Mostra-se ainda sob que condições intervenções de política podem reverter o padrão de especialização induzido pela vantagem comparativa inicial e ainda assim obter ganhos de bem estar.This paper analyses the effects of agricultural productivity gains on the industrialization process and on the long run growth rate of the economy. The model allows endogenous gains in agricultural productivity and, besides that, it is assumed that accumulated experience in the manufacture sector exerts a positive impact on agricultural productivity. The model shown that a necessary condition to the decline of industrial employment, due to comparative advantage in agriculture, is that the economy of the rest of world has poor industry/ agriculture integration. Finally, it is also shown that interventionist can reverse specialization induced by initial comparative advantages.

    Full Text Available The horticulture production units in the Green Belt of Gran Rosario appeared in a space traditionally used to the exportable agricultural production. Presents since the XIXth century in the area, they were growing in function of the demographic growth to the first half of 1970 approximately, when the international prices paid for the soya made this leguminous a great competitor for land. The increasing of agricultural production implied an excessive pressure over the natural environment of the rural spaces, like an alteration of the working and living conditions of the people related to this territory. This work wonders about the modifications that happened in the local social horticultural structure in the last thirty years.Las unidades de producción hortícola del Cinturón Verde del Gran Rosario surgen en un espacio tradicionalmente priorizado para la producción agropecuaria exportable. Presentes desde el siglo XIX en el área, fueron incrementándose en función del crecimiento demográfico hasta aproximadamente mediados de la década de 1970, cuando los precios internacionales pagados por la soja convirtieron a esta leguminosa en una ventajosa competidora por tierra. El incremento de la producción agrícola implicó una presión excesiva sobre el entorno natural de los espacios rurales, como una alteración de las condiciones de trabajo y de vida de las personas vinculadas a este territorio.

En este sentido, el International Accounting Standards Board (IASB emitió la International Accounting Standards (IAS 41 en la cual prevé la mensuración al justo valor de los activos biológicos y productos agrícolas. En este paper abordaremos el sector vitivinícola portugués, por ser aquél que tiene un peso más significativo dentro de la actividad agrícola y analizamos la IAS 41 y su proceso de desarrollo, enfocando la visión de los principales intervinientes en el proyecto de norma. Por fin, abordamos un estudio empírico efectuado con base en datos recogidos a través de investigación a las empresas con la Clasificación Portuguesa de las Actividades Económicas (CAE 15931. A nivel empírico, para que percibamos cuáles son los factores influyentes en la aplicación de la norma, adoptamos los análisis descriptivo, factorial, de clústeres y discriminante. A pesar de las limitaciones de la investigación, los resultados obtenidos permiten concluir que los inquiridos dieron más relevancia a las variables relacionadas con la aplicabilidad de la norma y asimismo, con la experiencia y el conocimiento de ésta y de otras normas, o sea, consideran la aplicabilidad de la norma relevante para el sector.

    In the Western world, increased consumption of carbonated soft drinks combined with a decreasing intake of milk may increase the risk of osteoporosis. This study was designed to reflect the trend of replacing milk with carbonated beverages in a group of young men on a low-calcium diet and studies the effects of this replacement on calcium homeostasis and bone turnover. This controlled crossover intervention study included 11 healthy men (22-29 years) who were given a low-calcium basic diet in two 10-day intervention periods with an intervening 10-day washout. During one period, they drank 2.5 l of Coca Cola per day and during the other period 2.5 l of semi-skimmed milk. Serum concentrations of calcium, phosphate, 25-hydroxycholecalciferol, 1,25-dihydroxycholecalciferol (1,25(OH)2D), osteocalcin, bone-specific alkaline phosphatase (B-ALP) and cross-linked C-telopeptides (CTX), plasma intact parathyroid hormone (PTH) and urinary cross-linked N-telopeptides (NTX) were determined at baseline and endpoint of each intervention period. An increase in serum phosphate (Pcola period compared to the milk period. Also, bone resorption was significantly increased following the cola period, seen as increased serum CTX (Pcola with a low-calcium diet induces increased bone turnover compared to a high intake of milk with a low-calcium diet. Thus, the trend towards a replacement of milk with cola and other soft drinks, which results in a low calcium intake, may negatively affect bone health as indicated by this short-term study.

    Full Text Available La determinación de la tracción de los tractores agrícolas acredita su empleo eficiente, por ejemplo en: disminución del tiempo oportuno de operación, reducción de daños físicos y terramecánicos, adecuadas característica ingenieriles, tipo y número de neumáticos tractivos y reducción de los costos. El objetivo de este trabajo fue la utilización de las ecuaciones de Micklethwaite, Bekker, Janosi-Hanomoto, y Brixius adaptadas al campo agrícola analizadas con el lenguaje de programación Visual Basic. En la metodología se utilizaron los procedimientos de aplicación de las ecuaciones, las relaciones algebraicas y procedimientos programáticos en Visual Basic 6, diagrama de flujo y el análisis en la tracción sencilla, doble, aperos de tiro y montados; todos, con transferencia de peso y análisis de inestabilidad. El programa desarrollado con sus códigos proporciona una interfaz de usuario intuitiva mediante la vinculación de bases de datos con especificaciones del equipo agrícola, características del neumático, datos del suelo, datos del apero y los coeficientes de las ecuaciones para predecir el rendimiento de un tractor y modelo seleccionados. El programa demostró ser accesible, con mecanismos de uso sin instalación, eficiente y versátil. Las ecuaciones se emplearon con un número de parámetros representativos del área, que pueden ser reemplazados o ampliados y aplicables al agro involucrando la humedad del suelo.

  20. O Brasil agrícola: o tortuoso e difícil “caminho da roça”

    Full Text Available Brasil atualmente é um dos maiores produtores de commodities agrícolas, tais como soja, café, carne (bovina, suína e de aves, açúcar e suco de laranja, e o país se orgulha disso. Essa é uma realidade que começou com a adoção da Revolução Verde na década de 1960 (alta tecnologia no campo, mecanização, insumos, seleção genética, etc., quando foi implantado um modelo de farmerização. Para se chegar a esse modelo de agricultura, concentrador e pouco democrático, o Brasil precisou de quase cinco séculos. Durante a maior parte desse longo período, a agricultura não era vista como atividade nobre, ao contrário, procurava-se superar a identidade agrária, visto que a atividade não conferia status. Em certa medida, o Brasil teve vergonha de ser agrícola. Neste trabalho, o objetivo é analisar como o Brasil, um país agrário, durante mais de três séculos teve dificuldades de assumir uma identidade agrária, especialmente em função da influência de uma mentalidade portuguesa não afeita às lides agrícolas.
