title: THE WIND TRANSPORT CONTRIBUTION IN THE PROCESS OF SHORELINE EVOLUTION

description: Abstract This paper evaluates the eolian transport importance for the morphological behavior of a 20 Km stretch on the coast of Ceará between the Ceará river mouth and the Cumbuco Beach. The research consisted of the comparison between the sand volume involved in the coastline migration between 1974 and 2001 and the dune formation potential that is based on the relationship developed by the formed angle between the coastline position and the eolian transport dominant direction. The resulting material volume from the coastline migration was calculated by multiplying the advanced or retreated area by the sum of the active berm height and the closing depth. The dune formation potential, calculated for each studied segment, demonstrated (1) to keep an excellent correlation with the measured volumes for the coastline migration and (2) that most of the segments have been submitted to a sedimentary deficit potential caused by the wind, excluding a few stretches where there is a beach feedback tendency by the eolian transport, through a 'bypass' process. The results have showed that the eolian activity may be fundamental for the coastline equilibrium, reinforcing, this way, the idea that the works involving the coastal dynamics need the eolian transport study so that they may appropriately represent the coastal dynamics of the studied area.

title: INFLORESCENCE PRODUCTION OF BROCCOLI CULTIVARS IN THE HOT AND HUMID CLIMATE OF CENTRAL AMAZONIA1

description: ABSTRACT Broccoli has great economic, social, and nutritional importance. Genetic improvements through breeding programs for this species made available cultivars with satisfactory production in hot and humid climates. Two experiments were conducted to evaluate the inflorescence production of broccoli cultivars (Ramoso and Cabeça groups) in the hot and humid climate of Central Amazonia. In experiment 1, Ramoso group cultivars were evaluated (Verão Ramoso Piracicaba, Ramoso Santana, Piracicaba, Piracicaba Precoce, Ramirez F1, Hanabi, Piracicaba Precoce Verão, and Hanapon ). In experiment 2, Cabeça group cultivars were evaluated (Green Storm, Strong, TPX-00925, Salinas F1, Bibou, Domador, Burney, and BRO 68 ). A randomized block experimental design was used, with eight treatments consisted of cultivars, and four replications for each experiment. Quantitative variables were evaluated, including inflorescence fresh and dry weights; and the qualitative variables evaluated showed the occurrence of undesirable characteristics in the inflorescences. Significant differences were found within the Ramoso group cultivars and within the Cabeça group cultivars evaluated. The broccoli cultivars that showed the best inflorescence production in the humid, hot climate of Central Amazonia were Verão Ramoso Piracicaba, Piracicaba Precoce Verão, Ramoso Santana, and Piracicaba Precoce of the Ramoso group; and Green Storm and Burney of the Cabeça group.

title: Effect of one time high dose “stoss therapy” of vitamin D on glucose homeostasis in high risk obese adolescents

description: ABSTRACT Objective To study the effect of using a one time high dose “stoss therapy” of vitamin D2 (ergocalciferol: VD2) on indices of insulin sensitivity {whole body sensitivity index: WBISI} and secretion {insulinogenic index: IGI} measured during an oral glucose tolerance test (OGTT) in obese adolescents with VDD (25 OHD; serum metabolite of vit D: &lt; 30 ng/dL). Subjects and methods In a randomized placebo controlled cross over design 20 obese adolescents with vitamin D deficiency (VDD) had baseline OGTT. Arm A received one time high dose 300,000 IU of ergocalciferol and Arm B received placebo. After 6 weeks the adolescents were reassigned to Arm A if they were in Arm B and vice versa. 25OHD, calcium, parathyroid hormone, comprehensive metabolic panel, urine calcium creatinine ratio were measured at each study visit. OGTTs to assess indices of sensitivity and secretion were done at baseline, 6 weeks and 12 weeks respectively. Results Adolescents were obese and insulin resistant (mean ± SD: mean age = 15.1 ± 1.9 years; BMI: 32.7 ± 9.8; homeostatic model of insulin resistance: HOMA-IR: 4.2 ± 2.8). Stoss therapy with VD2 increased 25OHD from baseline (16.7 ± 2.9 to 19.5 ± 4.5; p = 0.0029) when compared to the placebo. WBISI (2.8 ± 1.9) showed a trend towards improvement in Rx group (p = 0.0577) after adjustment for covariates. IGI (3 ± 2.2) showed an improvement in both Rx and placebo groups. Conclusions Our study demonstrated that using a high dose of VD2 (300,000 IU) did not have any beneficial effect on insulin sensitivity (whole body sensitivity index {WBISI}) and secretory indices (insulinogenic index {IGI}) in obese adolescents. High dose “stoss therapy” of VD2 did not appear to have any beneficial effect on glucose homeostasis on obese adolescents.

title: The Buritizal meteorite: classification of a new Brazilian chondrite

description: Abstract On August 14, 1967, the reporter Saulo Gomes, working at TV Tupi, went to a small city in the State of São Paulo called Buritizal to investigate reports of a meteorite fall and write a newspaper report. He actually recovered three fragments of the meteorite at a small farm. In 2014, he donated one of the fragments to the Museu Nacional of the Universidade Federal do Rio de Janeiro (MN/UFRJ). We named this meteorite Buritizal and studied its petrology, geochemistry, magnetic properties and cathodoluminescence with the intent to determine the petrologic classification of the meteorite. In this manner, the Buritizal meteorite is classified as an ordinary chondrite LL 3.2 breccia (as indicated by lithic fragments). The meteorite consists of ~ 2% of metallic Fe,Ni and many well-defined chondrules with ~ 0.8 mm in average diameter. An ultramafic ferromagnesian mineralogy is predominant in the meteorite, represented by olivine, orthopyroxene, clinopyroxene, Fe-Ni alloy, troilite and glass. The total iron content was calculated as 20.88 wt%. Furthermore, the meteorite was classified as weathering grade W1 and shock stage S3. Buritizal is the 25th observed meteorite fall recovered in Brazil, of 70 meteorites known from Brazil. Thus, the study of the Buritizal meteorite is very important and relevant for the Brazilian scientific community.

title: Productive Development Partnerships: an essay on the construction of strategic product lists

description: ABSTRACT This is an essay on the construction of strategic product lists for the Brazilian Unified Health System (SUS) eligible for the submission of proposals for Productive Development Partnerships (PDP). The objective of this study was to critically analyze the process of constructing these lists, reviewing the criteria used, the interaction currently existing with the evaluation of health technologies, the collaboration between decision makers and researchers or reference institutions, and the influence of the composition of the list on the outcome of the projects and reach of the objectives of the initiative. It was found that the use of scientific evidence and collaborative actions of researchers are reduced in decision making, and that the composition of the list has a great influence on the outcome of the PDP, and its construction is a key factor for the success of this initiative and the internalization of technologies. A suggestion for organizing the list-making work is the regimental definition of the use of an independent rapid response program organized between the government, the academy, and institutions involved in PDP approvals, so that the best scientific evidence is available to policy decision makers in the short term.

title: NFC technology acceptance for mobile payments: A Brazilian Perspective

description: Abstract Purpose: This study investigates the acceptance of NFC technology for payment through mobile in a Brazilian context, which allow knowing the factors that influence directly or indirectly in that acceptance. Design/methodology/approach: Through an online and self-administered questionnaire and using the snowball sampling procedure on social networks, the final sample consisted of 423 mobile phone users in Brazil and the technique used to prove the hypotheses was the Structural Equation Model. Findings: The results show that attitude, personal innovation in IT and perceived usefulness are determinants of future intention to use the NFC technology for payments in Brazil. Originality/value: The proposed model has a predictive power of intention to use NFC payment of 71%, demonstrating that it includes background with a large predictive power of acceptance of NFC technology which led us to highlight the main implications for the management and development of new studies in this field.

title: Long-term outcome after bilateral adrenalectomy in Cushing’s disease with focus on Nelson’s syndrome

description: ABSTRACT Objective We analyzed the clinical, biochemical, and imaging findings of adrenalectomized patients with Cushing’s disease (CD) in order to compare the characteristics of those who developed Nelson’s syndrome (NS) versus those who did not develop this complication (NNS), aiming to identify possible predictive factors for its occurrence. Subjects and methods We performed a retrospective review of the clinical records of a group of patients with CD who underwent TBA between 1974 and 2011. Results Out of 179 patients with CD, 13 (7.3%) underwent TBA. NS occurred in 6 of them (46%) after a mean of 24 months from the total bilateral adrenalectomy (TBA). Age at diagnosis, duration of Cushing’s syndrome (CS) until TBA, and steroid replacement doses were similar in both groups. Initial urinary cortisol levels (24-hour urinary free cortisol [UFC]) were significantly higher in the NS group than in the NNS group (p = 0.009). Four patients in the NS group and three of those in the NNS group received radiotherapy before TBA (p = 0.26). Three patients in the NS group presented residual tumors before TBA, compared with none in the NNS group (p = 0.04). At 1 year after TBA, the median ACTH level was 476 ng/L (240-1500 ng/L) in the NS group and 81 ng/L (48-330 ng/L) in the NNS group (p = 0.0007). Conclusion In conclusion, a residual tumor before TBA, higher 24-hour UFC at diagnosis, and increasing ACTH levels within 1 year after TBA emerged as predictive factors of development of NS.

title: Is severe early childhood caries predictive of caries and fluorosis in permanent teeth? Ten-year follow-up

description: Abstract Introduction Severe early childhood caries is defined as the presence of any sign of decay in children younger than three years. Objective This retrospective longitudinal observational study investigated caries and fluorosis in children with S-ECC from a city with fluoridated water. Material and method We included children under the age of three years who followed a maternal and child dental care program between the years of 1997 and 2003. The children were divided into 2 groups: group 1 (S-ECC) and group 2 (no caries). Guardians were contacted by telephone or mail. Caregivers completed questionnaire on socio-demographic and behavioral variables. The clinical dental examinations were performed in a dental clinic to assess caries experience and dental fluorosis. Multiple linear regression was used to determine factors associated with DMFT, and multivariate analysis by multiple logistic regression was used to determine the possible independent factors associated with the occurrence of fluorosis. Result The sample consisted of 126 patients aged 8-12 years, of whom 52.4% were male. The presence of S-ECC increased the DMFT by an average of 0.84 (p = 0.02). Both the frequency of tooth brushing and the use of standard toothpaste were protective factors from the development of caries in the permanent dentition (p &lt;0.05). Parents who reported that their children refused to brush their teeth had 70% less chance of developing fluorosis (p = 0.02). Conclusion The presence of S-ECC was a risk factor for the development of caries in the permanent dentition, but not for the development of fluorosis.

title: The Impact of Private Equity and Venture Capital Funds on post-IPO Operational and Financial Performance in Brazilian invested companies

description: ABSTRACT The present article seeks to analyze the legacy and its persistence over time in terms of financing and operational policies and financial performance, of companies invested by Private Equity and Venture Capital funds (PE/VC). The PE/VC industry is characterized by the function of identifying companies with large return potentials and that grow arithmetically - due to capital constraints - to provide adequate and necessary sources of capital and experience for exponential growth. In this study, we used four measures that relate to companies' financial policies and their persistence over time: i) cash & equivalents; ii) leverage; iii) Return on Assets (ROA); and iv) sales growth. The results suggest that PE / VC invested companies imply higher levels of cash & equivalents and are associated with a lower level of leverage during the first 5 years after the IPO. In addition, companies financed by PE/VC funds show higher profitability and higher sales growth compared to non-invested companies in the short term, i.e., in the first 3 years after the IPO.
