Citronella oil is one of the essential oils derived from the leaves and stem of lemongrass (Cymbopogon nardus). At present, most of the lemongrass oil industry in Indonesia is still in the form of upstream industries which only provide crude purified oils with low purity for export with a fairly low sales value. technology in improving the purity of citronella oil needs innovation in following the development of the industrial revolution 4.0. This article presents an overview of the research opportunities in the development of distillation for fractionating citronella oil referring to automation of optimization processes in the vacuum fractional distillation accompanied by inspection of the quality of essential oil isolation run in the line process based on smart sensors integrated in a computer program. The combination technique of quality control of essential oils in line process system combined with the optimization technique of the vacuum fractional distillation process has not been studied by advanced researchers. Therefore, this study has a state of the art process engineering and smart sensor-based quality control systems that can be developed for strengthening the Indonesian citronella oil industry.

Luwak coffee is one of the Indonesia traditional coffee that known globally because of its unique aroma and flavor. Luwak coffee was produced by a fermentation process in luwak digestion by involving microbe that can be found in luwak digestion. Luwak coffee fermentation process using luwak animal has many weakness such as inefficient production processes, and final product quality that always makes consumers hesitate in terms of its hygiene and halal. Therefore some research to produce coffee with the quality of luwak coffee without using luwak began to be developed. Several methods of fermentation to produce coffee with quality luwak coffee are discussed in this paper, such as fermentation by in vitro technique

This work investigates strategic management processes of projects involved in the Brazilian aerospace field, addressing the Regional Center of the Amazon of the National Institute of Space Research. It proposes an approach in the monitoring of the evolution of projects by evaluation of professional performance, showing results in graphs and the need to survey and follow the most evident and significant technological advances in the mapping environment of land use and land cover in the Amazon. It addresses the main difficulties faced in the process of managing projects and people to achieve goals, needing to know the Geographic Information System tools used by employees, such as Terramazon, and their respective times consumed in this type of software. The work intends to serve as a basis for investigating, developing and implementing new management options that will reduce the efforts required by managers and administrators during the process of monitoring the evolution of projects. The methodology of Project Management Institute (PMI) and its Guide to the Project Management Body of Knowledge (PMBOK Guide) was used in this research work, ensuring an international quality. © 2018 Portland International Conference on Management of Engineering and technology, Inc.

Aluminum is one of the most abundant metals in the earth's crust. Although it shows no known biological function, it is recognized as an adjuvant in vaccines for human and veterinary uses. This study aims to evaluate the role of lifestyle and environment in the promotion of chronic disease. In it, we associated two factors: chronic exposure to aluminum and high-fat diets. Thus, we aimed to determine whether the association of long-term exposure to aluminum and high-fat diets affects the NTPDase and 5′-nucleotidase activities in the blood platelets and lymphocytes obtained from the mesenteric lymph nodes of young rats. In fact, the ectonucleotidase activities were shown to be upregulated upon exposure to aluminum plus high-fat diets. As a result, we can suggest that the progressive upregulation of ectonucleotidase activities that we observed could be controlling the extent of inflammation and immune response. © 2017 Wiley Periodicals, Inc.

Functions of dietary fiber include increasing stool mass and reducing intestinal transit time which can be used to prevent constipation. This study aims to determine the ability of mixed catfish meatballs and sea grass flour to reduce constipation through two stages. The first stage was to get the best meatball quality (ratio of tapioca composition and seaweed flour manipulated at 100%: 0%; 90%: 10%; 80%: 20%; 70%: 30%) followed by the second stage which was in vivo testing for rat with doses of meatballs manipulated at 2 g, 4 g, 6 g and 8 g. Research data were analyzed with one-way variance analysis with a confidence level of 95%. Composition of tapioca and seaweed flour at 70%: 30% was the best fish meatball formula resulting in these data: 64.90% moisture content, 2.00% ash, 5.76% fat, 13.91% protein, 13.43% carbohydrate, total food fiber 5.94%) with sensory value: appearance 8.67 (smooth, not hollow, and bright surface), flavor 7.00 (less fish flavor), taste 6.67 (less meat fish taste), texture 9 (solid, compact, springy). The in vivo test showed that administration of 2 g / 200 g weigh body of rat was able to produce rat feces back to normal condition (47.93% moisture content) with a frequency of defecation 21 times per day (no constipation any more).

The aim of this work was to perform chemical and physicochemical analysis of oil of the camu camu (Myrciaria dubia (H.B.K) Mc Vaugh) seeds obtained at Caçari beach, on the banks of the Cauamé river, in Boa Vista city, Roraima state, Brazil. From the seeds, the dark green oil was 2.88% yield. The physical and chemical properties of the oil through the1H and13C NMR spectra: iodine content (55.39 g I2 100g-1), saponification index (178.14 mg KOH g-1), acidity (1.46 mg KOH g-1), olefinic/aliphatic hydrogen ratio (0.36), average molecular weight (934.16 g mol-1). Analysis of the signal displacements in1H and13C NMR spectra confirmed the presence of the fatty acid functional groups and unsaturated fatty acid unsaturations, so the concentration of linolenic acid was 0.43%, acid 12.02% oleic, oleic was 62.49% and saturated fatty acids 25.10%. The quantitative analysis of minerals by ICP-OES showed concentrations of elements: K, Na, P, Si (> 100 ppm);Mg, S (10 to 100 ppm) and Ti (-1). Copyright © 2018, AIDIC Servizi S.r.l.

The aim of this work was to perform analysis of the a-tocopherol content by HPLC in Amazonian fruits consumed in Roraima state, Brazil, namely: ata brava, açaí, bacaba, buriti, buritirana, yellow murici, red murici, piaçaba braba, pupunha varieties red and yellow and tucumanzinho. A high concentration of the vitamin in the açaí pulp (1101.11 mg L-1) and of the ata brava seeds (644.27 mg L-1) was observed, but other fruits such as buritirana pulp (166.34 mg L-1), red murici (179.52 mg L-1), and piaçaba brava (8.77 mg L-1) presented low amounts of a-tocopherol. As for the yellow and red varieties of pupunha and the tucumanzinho, no presence of the isomer was detected. Identification and quantification of a-tocopherol cited in this work are unpublished for the ata brava, buritirana and red murici, as for the other fruits studied there were variations. Amazonian fruits may present a-tocopherol in its lipid composition, which is one of the most bioactive isomers of vitamin E, for this reason. Copyright © 2018, AIDIC Servizi S.r.l.

Fingerprints are unique to each individual who contributes to human identification in forensic cases. In this sense, the present work aimed to synthesize 1H-pyrazol-1-yl-4-phenylthiazoles and apply them as powder agents to reveal latent finger marks as an alternative and low cost related to powders found on the market. The compounds were characterized by infrared; fluorescence; 1H NMR; 13C NMR; laser diffractometer and SEM. In addition, cytotoxicity was also evaluated in oral keratinocytes showing high cell viability. The result of the hemolytic assay revealed that compound 2a does not present red cell cytotoxicity. The prepared powders were applied to fingermarks deposited on different surfaces providing quality visualization at level three so that human identification is possible.
