2. Malaria elimination in Bhutan: asymptomatic malaria cases in the Bhutanese population living in malaria-risk areas and in migrant workers from India
ABSTRACT In 2018, Bhutan reported 54 cases of malaria, of which six were indigenous, 14 introduced and 34 imported. Considering the continuous reduction in the number of indigenous cases, Bhutan plans to eliminate malaria by 2025 under the Bhutan Malaria Elimination Strategy. The study was conducted to assess the presence of asymptomatic plasmodial infection

4. A new cement slurry modified with chitosan/alginate interpenetrating networks and hydroxyapatite - structural characteristics after long-term contact with hyper-saline produced water from oil well operations
ABSTRACT Oil is an important source of energy, mainly in developing countries. Important research has been conducted to find cementing procedures that guarantee safe and cost-effective oil exploration below pre-salt layers. This work aimed to make a new cement paste with cement, seawater, silica, biopolymers (chitosan and sodium alginate) and hydroxyapatite

5. Poly(lactic acid)/thermoplastic starch sheets: effect of adipate esters on the morphological, mechanical and barrier properties
Abstract Blends of poly(lactic acid) (PLA) and thermoplastic starch (TPS) plasticized with adipate esters (diisodecyl adipate and diethyl adipate) having different molecular weight were used to produce sheets. The calendering-extrusion process at a pilot scale was used, and the mechanical, barrier, and morphological characterization of the obtained materials

6. Evolução hematológica e do conteúdo de ferro em recém-nascidos de termo e pré-termo tardios, com e sem crescimento intrauterino restrito, durante os primeiros dois meses de vida / Hematological and iron content evolution in term and late pre-term newborns, with and without intrauterine growth restriction, during the first two months of life
Iron (Fe) acts in several metabolic processes, especially neurodevelopmental ones, which body content is still the difficult access and could be influenced by factors, such as, prematurity and Intrauterine Growth Restriction (IUGR). This study aimed at describing the hematological evolution and iron body content in Term (T) and Late Pre-Term (LPT) Newborns (

7. FORAGE INTAKE AND PERFORMANCE OF SHEEP GRAZZING Cynodon dactylon var. dactylon UNDER DIFFERENT ALLOWANCES OF LEAF LAMINA / CONSUMO E DESEMPENHO DE OVINOS MANTIDOS EM PASTAGEM DE Cynodon dactylon var.dactylon COM DIFERENTES NÍVEIS DE OFERTA DE LÂMINAS FOLIARES VERDES
The effect of different allowances (3, 6, or 9 kg of dry matter (DM)/100 kg of body weight (BW)) of leaf lamina (ALL) on the traits of a bermudagrass pasture Cynodon dactylon var. dactylon) and on the performance of sheep was evaluated. The experiment was conducted in five periods of 28 days, from october 2008 to february 2009, in a fully randomized arrangem

8. Adjusted likelihood ratio statistics in beta regression models / Ajustes para o teste da razão de verossimilhanças em modelos de regressão beta
We consider the issue of performing accurate small-sample likelihood-based inference in beta regression models, which are useful for modeling continuous proportions that are affected by independent variables. We derive Skovgaards (Scandinavian Journal of Statistics 28 (2001) 3-32) adjusted likelihood ratio statistics in this class of models. We show that the

9. Genética de populações e reinterpretação da história demográfica de remanescentes de quilombos: uma comparação entre três populações do nordeste brasileiro
The remanescentes de quilombos are multiethnic societies whose origins are related to the presence of African slaves in Brazil. The demographic history of these populations has been studied using historical, demographic, ethnographic and genetic sources. The present work aims to evaluate the origin and the impact of recent and ancient waves of immigration up

10. PRESERVAÇÃO DE ÓRGÃOS EM CÂNCERES DE CABEÇA E PESCOÇO: ANÁLISES DA QUALIDADE DE VIDA E PARÂMETROS VOCAIS PÓS-TRATAMENTO
Head and neck cancer has high prevalence and morbidity. Although radiotherapy has shown good results, function is not always fully preserved. This study aimed to investigate the occurrence of voice complaints after radiotherapy and/or chemotherapy, with subjective and objective assessments of voice quality and quality of life of head and neck cancer patients

11. Predição de fator de simultaneidade através de modelos de regressão para proporções contínuas / Prediction of simultaneity factor using regression models for continuous proportions.
The simultaneity factor is fundamental in planning gas distribution networks. It is a multiplicator between 0 and 1 that adjusts the theoretical total consumption of a number of devices to realistic conditions. In 2005, the Instituto de Pesquisas Tecnológicas (IPT) and the Companhia de Gás de São Paulo (COMGÁS) performed a study in which the simultaneity

12. Growth and partitioning of green pepper assimilates as a function of spatial arrangements and row spacings / Crescimento e partição de assimilados de pimentão em função de arranjos espaciais e espaçamentos na fileira
Planting density is associated with management practices and competition for water, light, and nutrients, and consequently with crop growth. The study was carried out in 2006 in Baraúna-RN, Brazil, in order to characterize Atlantis green pepper growth at various spatial arrangements (1.5 m × 0.5 m; 1.6 m × 0.4 m; and 1.7 m × 0.3 m) and row spacings (0.2
