Abstract: objective: to evaluate the effectiveness of adding vildagliptin to the treatment of patients with inadequately controlled type 2 diabetes mellitus (t2dm) treated with a combination of metformin and a sulphonylurea. subjects and methods: 37 t2dm patients with hba1c ranging from 7.7% to 12.4% (mean of 9.30 ± 1.38), despite the use of metformin in combination with a sulphonylurea, were additionally treated with vildagliptin (100 mg/day) for at least 6 months. results: during triple oral therapy (tot) hba1c levels < 7% were achieved in 11 patients (29.7%), whereas levels of fasting plasma glucose (fpg) < 120 mg/dl were observed in 12 patients (32.4%). both findings were observed in 10 patients (27.0%). compared to nonresponsive subjects, lower mean baseline hba1c and fpg levels were seen in responsive patients, but the difference was only statistically significant for fasting plasma glucose (fpg). moreover, there was considerable overlap between the two groups. conlusion: our preliminary results suggest that tot with metformin, a sulphonylurea and vildagliptin may be useful for some t2dm patients nonresponsive to combination therapy with metformin and sulphonylurea.
Electron-Domain Wall Interaction with a Ferromagnetic Spherical Domain Wall  [PDF]
Leonardo dos Santos Lima
Journal of Modern Physics (JMP) , 2016, DOI: 10.4236/jmp.2016.713148
Abstract: The interaction between an electron with a three-dimensional domain wall was investigated using the Born’s expansion of the S scattering matrix. We obtain an influence of the scattering of the electron with the ferromagnetic domain wall in the spin wave function of the electron with the aim to generate the knowledge about the state of the electron spin after the scattering. It relates to the recent problem of generation of the spin polarized electric current. We also obtain the contribution of the electron-wall domain interaction on the electric conductivity \"\", through the wall domain, where we have obtained a peak of resonance in the conductivity for one value of \"\" .
An Empirical Model for Dinitrogen Gas Emission from Inland Waters  [PDF]
Elizabeth Sikar, Marco Aurelio dos Santos, Ednaldo Oliveira dos Santos
Atmospheric and Climate Sciences (ACS) , 2019, DOI: 10.4236/acs.2019.91001
Abstract: The motivation to calculate this empirical model resulted from often observing—at the time disconcerting—excess dinitrogen gas (N2 concentration > background concentration) in bubble-gas emission samples, collected primarily for the purpose of carbon budget research, from Brazilian rivers and reservoirs sampled during roughly 100 field surveys lasting 4 days each on average and executed between years 2000 and 2012. We model the (serendipitously) measured dinitrogen gas above environmental concentration (N2aec) escaping in bubbles from Brazilian rivers as a function of dissolved nitrogen (N) in water. To this model, we mathematically add a pre-existing model of diffusively emitted denitrified dinitrogen (also as a function of dissolved N) from streams in the United States of America (USA). The resulting model predicts denitrified dinitrogen water-air emission from inland waters in the USA, China and Germany.
O ensino de recrea o: repensando algumas práticas
Edmilson Santos dos Santos
Movimento , 2001,
Abstract: Thispaper aims at analyzing the topics by which the books which suggest practical activities in recreation justify certain procedures and authorize certain academic practices as valid. To reach this result 22 books dealing with child recreation were analyzed. The strategies used by experimental literature to build truth on the discipline of Recreation are subjected to the separation between theory and practice, the backing up of the child's heteronomy and the simplification of reality.
Application of Extended Multiplicative Signal Correction to Short-Wavelength near Infrared Spectra of Moisture in Marzipan  [PDF]
Pedro dos Santos Panero, Francisco dos Santos Panero, Jo?o dos Santos Panero, Henrique Eduardo Bezerra da Silva
Journal of Data Analysis and Information Processing (JDAIP) , 2013, DOI: 10.4236/jdaip.2013.13005
Abstract: Short-wavelength near infrared spectroscopy (SW-NIR) is a very rapid, versatile and precise technique, which can be used in many different situations and for very types of products and chemical compounds. Extended multiplicative signal correction (EMSC) is a modification of the standard MSC pre-processing method that allows the separation of physical light scattering effects from chemical (vibrational) light absorbance effects in spectra. In this paper, the EMSC is applied and compared with first derivate, second derivate, MSC and SNV in combination of PLSR to obtain robust models in terms of accuracy and predict ability with a reduced calibration data set using SW-NIR spectra of moisture in marzipan. The Extended Multiplicative Signal Correction—EMSC and combination methods provide the best results in terms of prediction ability and calibration SW-NIR spectra of moisture in marzipan. The best classification results were obtained by Extended Multiplicative Signal Correction followed by second derivates.
Social Protection in a Matching Model: The Case of Basic Income  [PDF]
Samir Amine, Pedro Lages Dos Santos
Theoretical Economics Letters (TEL) , 2012, DOI: 10.4236/tel.2012.21005
Abstract: Faced with increasing poverty and the relative inefficiency of their redistribution systems, many countries are turning to new instruments of social policy. Many economists found there an opportunity to present the mechanism of basic income as the new way forward by the modern social protection. We show that, in a matching model with differentiation agents, the introduction of the basic income has no effect on the balance of the labor market.
More than Just a Game: The Power of Social Media on Super Bowl XLVI  [PDF]
Fernanda Bruno dos Santos, Jonice Oliveira
Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.32018
Abstract:

The evolution of social media in the recent years promoted the appearance of a new category: social media based on check-in. It enables the user to define their identity through information sharing. This paper aims to show the evolution of these media highlighting the effects and changes they cause in society through Super Bowl XLVI scenario, besides indicating the important role they have for the companies and marketing.

Land Use Change Trajectories for Wetland Management (Mogi-Gua?u Floodplan River, Southern Brazil)  [PDF]
Angela Terumi Fushita, José Eduardo dos Santos
Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.510006
Abstract: Natural and anthropogenic factors are responsible for changes in wetland function and structure. This research deals with the complexity of interactions among flood attributes, climatic data and land use trajectories to track the impact of land use changes for wetland management, over 30 years (1984- 2014). This paper presents a multi-temporal analysis of a floodplain to know the inter-annual ecohydrological variability, including extraordinary events of floods and droughts, using indicators of hydrological regime. It also presents a quantitative description of the geospatial variability in the Mogi Guaçu wetland components to assess the changes in the conversion, replacement, of wetland landscapes by anthropic growth activities. Flood attributes and anthropogenic pressures have altered temporal habitat variability in changes on the river course, in sandbars extent, and oxbow lake genesis and extinction, with a decline in the biota dependent on these habitats. These results have significant implications of the quick expansion of anthropogenic activities and provide key information about the impact of land use changes on the wetland function and structure. It is an objective tool to help the environmental management of wetland areas.
“Shameless” Sedentarism: Individual Responsibility for Health?  [PDF]
Marcos Bagrichevsky, Doiara Silva dos Santos
Psychology (PSYCH) , 2018, DOI: 10.4236/psych.2018.94048
Abstract: The text critically addresses the polarity between discourses on sedentary and healthy lifestyles, contextualized by new technological resources for searching and disseminating information about health. The argument is that contempora-neous technoscientific rationality has created an “economy of truths” that, with the perspective of leading to safe lifestyles, have been prescribing a normative set of self-discipline ideals which generates anxiety and distress. In the hegemonic production of these regimes, sedentary lifestyle presents itself as a health risk, equivalent to moral failure and an unacceptable lack of self care. We highlight that the abundance of discourses about lifestyles and risk, seen as biopolitical devices imbricated in the processes of communication in health matters, deserves attention for their ethical and political implications. The display of lifestyles associated with the consumption and the production of narratives that perversely influence our culture has taken us far away from a socially possible notion of health. Finally, the regulatory essence of such symbolic references in building knowledge systems that have been (re)defining what means to be healthy, normal, unhealthy is discussed.
Viability and Action of CPL Lectin on in Vitro Germinability of Pollen Grains of Malpighia emarginata DC.—(Malpighiaceae)  [PDF]
Alexsandro dos Santos Sousa, Evandro José Lima Rego, Francisco de Assis Ribeiro dos Santos
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.47A1007
Abstract:

This study aimed to observe the viability of the pollen grains of Malpighia emarginata DC. (West Indian cherry) and the action of a lectin in their germination. Lectins are proteins that specifically interact with carbohydrates, but don’t modify them and bind with high affinity and specificity, promoting a transfer of information that is clearly central to many cellular processes in living beings. For the viability test was used aniline blue in lactophenol. The in vitro germination test used was the hanging drop method, in control medium containing sucrose, boric acid, calcium nitrate and agar. The experiment dealt with three different treatments in order to pollen germination: growing medium without addition of lectin, with 1.0 μg/ml and with 3.0 μg/ml CPL lectin. This lectin is extracted from seeds of Crotalaria pallida L.-Leguminosae. Data on pollen grains were analyzed by one-way ANOVA, with 95% reliability and comparison of averages by Turkey test at 5% probability. It was found that despite previous high viability of the pollen grains (c. 70%), a germinability rate has been low, yet exceptionally larger in pollen samples placed on a growing medium with addition of 3.0 μg/ml of CPL lectin (24%). There was no significant difference among the pollen grains germinate in medium without lectin and those in medium with the addition of only 1.0 μg/ml. According to data obtained in the treatments, CPL lectin, with concentration of 3.0 μg/ml, influenced the formation of the pollen tube and thus more pollen germinated in Malpighia emarginata.
