Microencapsulation Stability of Stevia Leaf Extracts of Stevia rebaudiana Bert Using Inulin-Chitosan  [PDF]
Mutmainah Mutmainah, Yohanes Martono, Yuvianti Dwi Franyoto, Lia Kusmita
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105925
Abstract:
Extract of Stevia leaf of rebaudiana Bert has a content that is easily oxidized by the presence of light and heating so it is not stable during storage. A microencapsulation process is carried out which aims to protect the contents in the extract. This study aims to determine the effect of storage temperature on the physical stability of the microencapsulation of Stevia leaf of rebaudiana Bert with a combination of encapsulants inulin chitosan. A study was conducted to determine the effect of temperature on the mi-croencapsulation stability of Stevia leaf of rebaudiana Bert over a period of 1 month. Tests carried out on the microencapsulation of Stevia leaf of re-baudiana Bert include the examination of the physical parameters of the microcapsules, namely the microencapsulation yield, moisture content, sol-ubility, flow rate, non-encapsulated and encapsulated extracts content and determination of particle distribution and morphological form. The test results show that the storage temperature does not affect the microen-capsulation stability of Stevia leaf of rebaudiana Bert, because the SEM test results did not change i.e. the particle size distribution of 1 - 1000 μm. The average yield obtained from making microencapsulation of Stevia leaf extract of rebaudiana Bert was 98.20%. Storage temperatures of 5?C, 25?C and 40?C affect the physical stability of the microencapsulation of Stevia leaf extract of rebaudiana Bert due to changes in the profile of physical characteristics during storage.
CHARACTERIZATION OF CAROTENOID PIGMENTS FROM BACTERIAL SYMBIONTS OF SEAGRASS Thalassia hemprichii

Journal of Coastal Development , 2010,
Abstract: Carotenoids are pigments that can be used in various applications including cosmetics and precursor ofvitamins A. Carotenoids are mostly found in higher plant leaves, fruit, and bacteria. Marine bacteriaassociated with seagrass Thalassia hemprichii collected from Menjangan Kecil Waters, KarimunjawaIslands were screened to produce the pigment and has allowed the use of these microrganism as anenvironmental friendly alternative source of new natural pigment. The isolation of bacterial symbionts onZobell 2216E medium from seagrass Thalassia hemprichii resulted in 20 isolates of which 8 bacterialsymbionts have produced pigments but only one bacterium positively synthesize carotenoids. Initial analysiswith atomic absorption spectrophotometric method revealed that the wave lengt of bacterial pigment were inthe range of 300-600 nm, which are categorized that within the group of carotenoid pigments. From theresults of molecular identification by 16S rDNA method, it was shown that bacterium TH8 was closelyrelated to Bacillus licheniformis with 98% homology value.
Forces in Struggle in the Country and the City Today in Brazil: Beyond a Dualistic Understanding  [PDF]

Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.31006
Abstract: Is it still possible to distinguish the line that separates the country and the city? How do rural and urban workers produce their life today? What are the characteristics that distinguish or approximate them? What movements of resistance have been observed? These questions guide our reflections about the relationship between urban and rural space. Based on a study in the urban pe-riphery and in encampments and settlements of the Landless Rural Workers Movements in Brazil, we seek to understand alternative forms of occupation of space today.
A nursing interface terminology: Evaluation of face validity  [PDF]
Maria Eulàlia Juvé Udina
Open Journal of Nursing (OJN) , 2012, DOI: 10.4236/ojn.2012.23030
Abstract: A range of different language systems for nursing diagnosis, interventions and outcomes are currently available. Nursing terminologies are intended to support nursing practice but they have to be evaluated. This study aims to assess the results of an expert survey to establish the face validity of a nursing interface terminology. The study applied a descriptive design with a cross-sectional survey strategy using a written questionnaire administered to expert nurses working in hospitals. Sample size was estimated at 35 participants. The questionnaire included topics related to validity and reliability criteria for nursing controlled vocabularies described in the literature. Mean global score and criteria scoring at least 7 were considered main outcome measures. The analysis included descriptive statistics with a confidence level of 95%. The mean global score was 8.1. The mean score for the validity criteria was 8.4 and 7.8 for reliability and applicability criteria. Two of the criteria for reliability and applicability evaluation did not achieve minimum scores. According to the experts’ responses, this terminology meets face validity, but that improvements are required in some criteria and further research is needed to completely demonstrate its metric properties.
Is the ATIC terminology oriented to nursing phenomena?  [PDF]
Maria Eulàlia Juvé-Udina
Open Journal of Nursing (OJN) , 2012, DOI: 10.4236/ojn.2012.24057
Abstract: The main goal of this observational and descriptive study is to evaluate whether the diagnosis axis of a nursing interface terminology meets the content validity criterion of being nursing-phenomena oriented. Nursing diagnosis concepts were analyzed in terms of presence in the nursing literature, type of articles published and areas of disciplinary interest. The search strategy was conducted in three databases with limits in relation to period and languages. The final analysis included 287 nursing diagnosis concepts. The results showed that most of the concepts were identified in the scientific literature, with a homogeneous distribution of types of designs. Most of these concepts (87.7%) were studied from two or more areas of disciplinary interest. Validity studies on disciplinary controlled vocabularies may contribute to demonstrate the nursing influence on patients’ outcomes.
Evolution of the Number of Students in Elementary and Secondary School in Portugal and Population Ageing  [PDF]
Cecília Rosa, Edgar Pereira
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57008
Abstract: In this work, we present an application of a mathematical model structured in classes (see [1]) for the study of the influence of population ageing in the evolution of the number of students in elementary school and in secondary school in Portugal, from 1995/96 to 2014/15 (see [2]). Based on historical data, some scenarios of projection are presented, with the aim of quantifying the young student population and its relation with the structure of the population age for the next school years in Portugal (from 2016/2017 to 2020/2021), in the various study cycles. Furthermore, we make a comparative analysis between the projection results presented here and in references [3] and [4]. The dynamic of the model comprises two stages: the first one represents the flow of students that go from one school year to the next, as well as the flow of students that enter or leave the educational system in a certain cycle of studies. The second stage represents the flow of students that go to the next cycle of studies. The simulations were done using Matlab.
Educa??o popular e pedagogia(s) da produ??o associada
Tiriba, Lia;
Cadernos CEDES , 2007, DOI: 10.1590/S0101-32622007000100006
Abstract: understanding the productive processes as spaces/times of human development, we consider the social and economic perspectives, explicitly or implicitly present in the training processes of workers associated in production -processes that are developed by "technicians" in (popular) collaborative economy. we foresee a collaborative production pedagogy that may contribute not only to question and dodge the cruel and exclusive logic of capitalism, but also to spread - within a class society - the germs of a working culture able to oppose the logic of capitalism. inspired by two educational materials that are a guiding light to educators/workers in collaborative (popular) economy, we pursue the productive/educational praxis integration, which requires, among other things, that work, education, popular economy and popular education be (re)united.

Abstract: those who do research in the area of translation history can profit from a knowledge of brazilian history and its methodology as well as from the authors who comment on different periods of their special interest. this knowledge can help them identify the effects of censorship and the development of translations produced during the vargas era (1939-53) which marks the industrialization of translation in brazil.
