Introduction: Altered gastrointestinal (GI) barrier integrity and subsequent microbial translocation may contribute to immune activation in HIV infection. We have reported that rosuvastatin improved several markers of immune activation in HIV+ participants, but the effect of statin treatment on markers of GI barrier dysfunction is unknown.Methods: SATURN-HIV is a randomized, double-blind, placebo-controlled trial assessing the effect of rosuvastatin (10mg/daily) on markers of cardiovascular disease, inflammation, and immune activation in ART-treated patients. Gut-barrier integrity was assessed by the surrogate markers intestinal fatty acid binding protein (I-FABP), a marker of enterocyte death, and zonulin-1, a marker of gut epithelial cell function. Levels of lipopolysaccharide binding protein (LBP) were measured as a marker of microbial translocation.Results: Rosuvastatin significantly reduced levels of I-FABP during the treatment period compared to the placebo. There was no effect of rosuvastatin treatment on levels of zonulin or LBP. Baseline levels of LBP were directly related to several markers of immune activation in samples from all participants, including soluble CD163, IP-10, VCAM-1, TNFR-II, and the proportion of CD4+ and CD8+ T cells expressing CD38 and HLA-DR. Many of these relationships, however, were not seen in the statin arm alone at baseline or over time, as inflammatory markers often decreased and LBP levels were unchanged.Conclusions: Forty-eight weeks of rosuvastatin treatment reduced levels of I-FABP, but did not affect levels of zonulin or LBP. The reduction in levels of inflammatory markers that we have reported with rosuvastatin treatment is likely mediated through other mechanisms not related to gut integrity or microbial translocation.SATURN-HIV is registered on clinicaltrials.gov; Identifier: NCT01218802
Acessibilidade e informação: a disparidade entre desenvolvimento tecnológico, leis e adaptações dos grandes portais brasileiros
Authors: Ritter Eduardo , Roque Thâmara
Published: July 2016

No dia 6 de julho de 2015 a presidente Dilma Rousseff sancinou a lei que cria o Estatuto da Pessoa com Deficiência. Com o objetivo de assegurar os direitos das pessoas com deficiência e dar autonomia para todos, inclusive no que diz respeito ao acesso à informação, comunicação e cultura, a lei busca corrigir o descumprimento de outras leis de acessibilidade, como o decreto de 2 de dezembro de 2004, que já previa que sites de grandes grupos de comunicação deveriam ser acessíveis a todos. Assim, baseados nos estudos de Corradi (2011) e Belarmino (2014) sobre comunicação e acessibilidade, e no conceito de cibercultura de Lévy (1999), é feita a análise de como alguns dos principais portais de notícias do Brasil não conseguem suprir o abismo informacional, atitudinal e tecnológico existente entre as condições de acessibilidade necessárias e o que é disponibilizado no contexto online pelos portais.

Authors: Nunes Francivaldo Alves , Silva Bruno de Souza
Published: July 2016

Este artigo tem a preocupação de analisar uma das experiências de colonização vivenciadas por colonos maranhenses que migraram para o Pará nas décadas de 1970 e 1980. Diante de um conjunto de depoimentos expressos por colonos que atuaram neste processo, buscamos entender o fenômeno da migração e colonização das terras do Pará, marcado pelo desafio de ocupar terras em que a floresta se constituía como paisagem predominante. É também um exercício de compreender as ações de homens e mulheres que no exercício de lidar com a terra e floresta constroem experiências de vida, estabelecem relações e asseguram a sobrevivência. Os deslocamentos, as ações de solidariedades e companheirismo, os conflitos entre os colonos e a busca por novas terras são questões também reveladas pelas experiências de migrantes maranhenses.

The underlying lesion, an enchondroma protuberans, can mimic either benign or malignant bone tumors. It was successfully treated with casting and intralesional treatment.

Conclusion:

Enchondroma protuberans is a rare entity that mimics enchondroma, osteochondroma, periosteal chondroma, or chondrosarcoma. Diagnosis is typically made through both radiographic and histologic means. In this case, the pathologic fracture was successfully treated with casting followed by intralesional curettage and bone-grafting. There was no evidence of recurrence at 18 months.
Plant Foods By‐Products as Sources of Health‐Promoting Agents for Animal Production: A Review Focusing on the Tropics
Authors: Guil‐Guerrero J. L. , Ramos L. , Moreno C. , Zúñiga‐Paredes J. C. , Carlosama‐Yepez M. , Ruales P.
Published: July 2016

In recent years there has been an increasing trend toward antibiotic use for animal production in tropical countries. As a suitable alternative to such drugs, several highly available plant‐food by‐products are reviewed here as supplements to feed farm animals. Such materials contain bioactive compounds, such as phenolics, carotenoids, saponins, essential oils, active peptides, and sterols. Phenolics are abundant in mango, avocado, and potato peels and are also found in pineapple and papaya by‐products. Phenolic compounds include (i) phenolic acids, which have antibacterial properties and can reduce the potential transmission of bacteria from cattle to the environment; (ii) flavonoids, which can exert antibacterial activity and induce synergy with other antibacterial agents against some resistant strains of bacteria; and (iii) tannins, which have benefits for ruminant productivity and health, although adverse effects have been also reported. Carotenoids enhance immunity in farm animals and are found in high amounts in papaya and tomato by‐products. Saponins occur in cassava by‐products and potato peels. Such compounds improve growth, feed efficiency, and health in ruminants, although there are also reports about their negative effects on farm animals. Recent investigations have shown that essential oils have a high potential as antibiotic growth promotant replacers due to their significant antimicrobial activity. These are abundant in mango peels. This review assesses the occurrence of active compounds in tropical crop by‐products, worldwide production, and the healthy effects of active compounds in farm animals.

Crop by‐products from tropical countries contain high levels of bioactive compounds.

Mango, avocado, and potato peels contain high concentrations of phenolics.

By‐products of tropical origin could help against microbial resistance to antibiotics.

Carotenoids stand out in papaya by‐products and essential oils in mango peels.
Feasibility of a Grain Sorghum Ratoon Cropping System in Southeastern Missouri
Authors: Mourtzinis Spyridon , Wiebold William J. , Conley Shawn P.
Published: July 2016

Sorghum [Sorghum bicolor (L.) Moench], has been identified as a crop with multiple uses, including as biofuel feedstock and livestock feed. The biomass‐related industries require a continuous supply of biomass, whereas livestock operations are looking for low‐cost feed alternatives to field corn. Ratooning of a high‐yielding low‐input crop such as sorghum can be beneficial to both enterprises across the mid‐southern United States. There have been multiple studies examining factors that contribute to grain yield; however, there is a lack of information about the performance of an early‐season ratoon sorghum system in the Mid‐South. Therefore, the objective of this 2‐year study was to evaluate the feasibility of a grain sorghum ratoon cropping system in southeastern Missouri by comparing the grain yields of a full‐season hybrid and an early‐season hybrid in a ratoon sorghum system. The early‐season hybrid exhibited similar or greater grain yields than the full‐season hybrid. The use of a 45 lb ac−1 N/30 lb ac−1 P2O5 starter fertilizer at planting showed no effect on grain yield. Side‐dressed nitrogen fertilizer increased the yield of the early‐season hybrid in three of the four location‐years. An economic analysis showed that the profit increase ranged between 26.4 and 74.4$/acre with the smallest profit increase observed at the fine‐sand site. Results suggest that recommendations for an early‐season ratoon hybrid N fertilizer should be specific for soil type. Nonetheless, based on the results of this study, such a system has high yield potential in southeastern Missouri and great potential on marginal ground for the entire Mid‐South region.
Determination of Sorption Coefficient of Phosphorus Applied for Sugarcane Production in Southwestern Florida
Authors: Muwamba A. , Nkedi‐Kizza P. , Morgan K. T.
Published: July 2016

Phosphorus is among the essential nutrients applied to sugarcane (Saccharum officinarum L.) fields in the form of a fertilizer mixture (N, P, and K) in southwestern Florida. Sorption coefficient is used for modeling P movement, and in this study, we hypothesized that the sorption coefficient determined using fertilizer mixture (N, P, and K) will be significantly different from values determined using KCl and CaCl2, the electrolytes most commonly used for conducting sorption experiments. Supporting electrolytes, 0.01 mol L‐1 KCl, 0.005 mol L‐1 CaCl2, deionized (DI) water, simulated Florida rain, and fertilizer mixture prepared in Florida rain were used to characterize P sorption. Immokalee (Sandy, siliceous, hyperthermic Arenic Alaquods) and Margate (Sandy, siliceous hyperthermic Mollic Psammaquents) are the dominant mineral soils used for sugarcane production in southwestern Florida; we used the A and Bw horizons of Margate soil and the A and Bh horizons of the Immokalee soil for sorption experiments in this study. Freundlich sorption isotherms described P sorption data. The Freundlich sorption isotherm coefficients followed the trend 0.005 mol L‐1 CaCl2 > 0.01 mol L‐1 KCl ≈ fertilizer mixture > simulated Florida rain ≈ DI water. Sorption coefficients were used for modeling P movement with HYDRUS 1D; similar P results were obtained with the 0.01 mol L‐1 KCl and fertilizer mixture electrolyte treatments. The sorption coefficient for DI water and simulated Florida rain overpredicted P movement. The P sorption data showed the importance of choosing the appropriate electrolyte for conducting experiments based on the composition of fertilizer.

Core Ideas

Soil was sampled from two sugarcane fields with Margate and Immokalee soils.

Electrolytes used were KCl, CaCl2, water, Florida rain, and fertilizer mixture.

The KD of P applied to sugarcane fields of southwestern Florida should be determined using KCl.

The kinetics of P applied to sugarcane fields of southwestern Florida can be studied using KCl.

Movement of P in sugarcane fields should be modeled using KD determined with KCl.

E-learning content being a barrier for e-learning is no longer true on today’s Internet. The current concerns are how to effectively annotate and organize the available content (both textual and non-textual) to facilitate effective sharing, reusability and customization. In this paper, we explain a component-oriented approach to organize content in an ontology. We also illustrate our 3-tier e-learning content management architecture and relevant interfaces. We use a simple yet intuitive example to successfully demonstrate the current working prototype which is capable of compiling personalized course materials. The e-learning system explained here uses the said ontology.

Pencarian dokumen pada jaringan Perpustakaan Digital (PD) berbasis peer-to-peer dengan arsitektur terdistribusi sangat mengandalkan koneksi antar-peer. Salah satu teknik pencarian yang umum digunakan adalah melalui pengiriman query secara broadcast kepada peer tetangga. Sayangnya cara ini kurang efisien karena berpotensi meningkatkan kepadatan lalu lintas jaringan. Selain permasalahan efisiensi, permasalahan lain yang dihadapi aplikasi PD adalah rendahnya kredibilitas PD dalam pertukaran data. Hal ini dapat dilihat dari rendahnya kualitas servis yang diberikan oleh sebuah PD. Pada penelitian ini penulis mengusulkan sebuah metode yang bernama Jaris. Jaris melakukan pencarian berdasarkan kemiripan antar-PD pada cache cluster dan kemiripan query pada cache query. Cara ini dilakukan untuk meningkatkan relevansi hasil pencarian dokumen dan menurunkan jumlah pesan yang dikirim. Jaris menggunakan mekanisme polling yang menggabungkan nilai QoS lokal dan global untuk meningkatkan kualitas transaksi. Pada uji coba penelitian, metode Jaris dibandingkan dengan metode random voting. Hasil percobaan menunjukkan kinerja Jaris lebih baik bila dibandingkan dengan random voting.

Triangleâ€™s checking in 3D faceted models is an essential step in gouging detection and elimination process. To check whether model surface intersects the tool, every triangle in the model has to be checked. Unfortunately, this process takes much time. Since the computer canâ€™t see and doesnâ€™t know which triangles located under the current tool position, then the triangles all over the surface model should be checked. To reduce the time, region checking at every position of tool has to be detected. Triangles that have to be checked are only in that region. The way of creating the region can be done by bucketing. Bucketing process will make some buckets as representation of regions and each bucket will be filled with triangles that lie in the corresponding region. There are several bucketing methods. This paper will explain all methods which have been implemented in the research.

Pengecekan segitiga dalam model 3 dimensi berfaset merupakan tahapan penting dalam deteksi gouging dan proses eliminasi. Untuk mengecek apakah permukaan model bersinggungan dengan alat, setiap segitiga pada model harus diperiksa. Akan tetapi, proses ini membutuhkan waktu yang lama. Segitiga-segitiga pada seluruh permukaan model harus diperiksa karena komputer tidak dapat melihat dan tidak mengetahui segitiga mana yang terletak di bawah posisi alat saat ini. Untuk mengurangi konsumsi waktu, pengecekan wilayah pada setiap posisi alat harus dapat dideteksi. Segitiga yang harus diperiksa adalah hanya yang berada pada wilayah tersebut. Cara yang dapat dilakukan untuk menetapkan wilayah adalah dengan menggunakan bucketing. Proses bucketing akan membuat beberapa bucket sebagai representasi dari beberapa wilayah dan setiap bucket akan diisi dengan segittiga yang terletak pada wilayah terkait. Terdapat beberapa metode bucketing. Paper ini akan menjelaskan semua metode yang telah diimplementasikan di dalam riset.

The various lighting intensity in a document image causes diffculty to threshold the image. The conventional statistic approach is not robust to solve such a problem. There should be different threshold value for each part of the image. The threshold value of each image part can be looked as classifcation problem. In such a classifcation problem, it is needed to find the best features. This paper propose a new approach of how to use grammatical evolution to extract those features. In the proposed method, the goodness of each feature is calculated independently. The best features then used for classification task instead of original features. In our experiment, the usage of the new features produce a very good result, since there are only 5 miss-classification of 45 cases.

Variasi intensitas pencahayaan pada citra dokumen akan menyebabkan kesulitan dalam menentukan nilai threshold dari citra tersebut. Pendekatan statistik konvensional tidak cukup baik dalam memecahkan masalah ini. Dalam hal ini, diperlukan nilai threshold yang berbeda-beda untuk setiap bagian citra. Nilai threshold dari setiap bagian citra dapat dipandang sebagai masalah klasifikasi. Dalam permasalahan klasifikasi semacam ini, dibutuhkan pencarian fitur-fitur terbaik. Di sini diusulkan sebuah pendekatan baru untuk mengekstrak fitur-fitur tersebut dengan menggunakan grammatical evolution. Nilai kebaikan dari masing-masing fitur akan dihitung secara saling lepas. Dalam percobaan yang dilakukan, tampak bahwa penggunaan fitur-fitur baru tersebut menghasilkan hasil yang sangat baik. Hanya ditemukan 5 kesalahan pengklasifikasian dalam 45 kasus.

Published: July 2016

This paper proposed a hybrid watermarking method that used dither quantization of Singular Value Decomposition (SVD) on average coefficients of Integer Haar Wavelet Transform (IHWT). The watermark image embeds through dither quantization process on singular coefficients value. This scheme aims to obtain the higher robustness level than previous method which performs dither quantization of SVD directly on image pixels value. The experiment results show that the proposed method has proper watermarked images quality above 38dB. The proposed method has better performance than the previous method in term of robustness against several image processing attacks. In JPEG compression with Quality Factor of 50 and 70, JPEG2000 compression with Compression Ratio of 5 and 3, average filtering, and Gaussian filtering, the previous method has average Normalized Correlation (NC) values of 0.8756, 0.9759, 0.9509, 0.9905, 0.8321, and 0.9297 respectively. While, the proposed method has better average NC values of 0.9730, 0.9884, 0.9844, 0.9963, 0.9020, and 0.9590 respectively.

Kajian investasi adalah kegiatan analisis untuk menilai manfaat dan biaya dari suatu investasi, dan dapat dijadikan justifikasi investasi. Penilaian investasi yang tradisional menggunakan pendekatan finansial dimana manfaat dan biaya yang ada dikuantifikasi dalam sejumlah nilai uang dan kemudian dibandingkan besar nilainya. Hal inilah yang dilakukan pada metode penilaian investasi dengan NPV dan ROI. ROV (Real Option Valuation) adalah sebuah alternatif penilaian investasi secara finansial. Berangkat dari filosofi yang sama dengan Financial Option, ROV memiliki keunggulan dalam menangani fleksibilitas, resiko, dan volatilitas yang mungkin terjadi dari sebuah investasi. Dengan demikian ROV dinilai lebih mampu menghargai sebuah investasi yang memiliki karakteristik tersebut. Penilaian investasi dengan ROV lebih mampu mengapresiasi investasi dibanding metode finansial tradisional, seperti yang ditunjukkan hasil NPV ROV pada kasus investasi Push E-mail yang lebih besar daripada NPV biasa. Hal ini disebabkan ROV mampu menghargai fleksibilitas dalam investasi yang memiliki pilihan-pilihan rencana investasi di masa depan.
