Penyebab pencemaran air pada ketiga sungai tersebut adalah limbah rumah tangga, limbah pertanian dan limbah industri. Kondisi ini dapat diatasi dengan melestarikan hutan di hulu sungai, dan tidak membuang limbah ke sungai baik cair ataupun padat.ÃÂ Kata kunci: analisi, pencemaran air, metode sederhana, sungai jangkuk, kekalik dan sekarbelaÃÂ ÃÂ Abstract: Research on watersÃ¢â¬â¢ pollution analysis have been conducted by simple analytical method at Jangkuk, Kekalik and Sekarbela rivers, West Nusa Tenggara Province. The aim of this research is to find out the watersÃ¢â¬â¢ pollution at those three rivers by looking at its physical, chemical, and biological test with a simple method. This research used daily tools and materials which easy to find so that ordinary people could analyze and prove the condition of the water in which they used every day. From the result of physical test, it showed that three of those rivers were polluted in term of smell, color, and temperature aspects. Based on biological test, it showed that there are activities of biological and chemical microorganisms on the water. From its chemical test, it showed that the pH of the sample water is 5 (positively acid). The chemical test found black spot at those three samples of water if filtered by tea. The waterÃ¢â¬â¢s color changed brown and found some oilly compound at the surface. This condition showed that the waterÃ¢â¬â¢s qualities are bad and not suitable to be consumed. The causes of the water pollution are mostly from home, agricultural, and industrial trashes. This problem could be solved by replanting the river side and not throwing the trashes materials (liquid or solid materials) into the rivers.ÃÂ Keywords: Analysis, Water Pollution, simple method, Jangkuk River, Kekaik River, Sekarbela River.

Abstract
Hot, dust-obscured galaxies, or “Hot DOGs,” are a rare, dusty, hyperluminous galaxy population discovered by the WISE mission. Predominantly at redshifts 2–3, they include the most luminous known galaxies in the universe. Their high luminosities likely come from accretion onto highly obscured supermassive black holes (SMBHs). We have conducted a pilot survey to measure the SMBH masses of five

Hot DOGs via broad Hα emission lines, using Keck/MOSFIRE and Gemini/FLAMINGOS-2. We detect broad Hα emission in all five Hot DOGs. We find substantial corresponding SMBH masses for these Hot DOGs (

), and their derived Eddington ratios are close to unity. These

Hot DOGs are the most luminous active galactic nuclei for their BH masses, suggesting that they are accreting at the maximum rates for their BHs. A similar property is found for known

quasars. Our results are consistent with scenarios in which Hot DOGs represent a transitional, high-accretion phase between obscured and unobscured quasars. Hot DOGs may mark a special evolutionary stage before the red quasar and optical quasar phases, and they may be present at other cosmic epochs.
Computing the Polarimetric and Photometric Variability of Be Stars

Abstract
We investigate variations in the linear polarization as well as in the V-band and B-band color–magnitudes for classical Be star disks. We present two models: disks with enhanced disk density and disks that are tilted or warped from the stellar equatorial plane. In both cases, we predict variation in observable properties of the system as the disk rotates. We use a non-LTE radiative transfer code bedisk (Sigut & Jones) in combination with a Monte Carlo routine that includes multiple scattering (Halonen et al.) to model classical Be star systems. We find that a disk with an enhanced density region that is one order of magnitude denser than the disk’s base density shows as much as

variability in the polarization while the polarization position angle varies by

. The ΔV magnitude for the same system shows variations of up to

mag while the Δ(B–V) color varies by at most

mag. We find that disks tilted from the equatorial plane at small angles of

more strongly reflect the values of polarization and color–magnitudes reported in the literature than disks tilted at larger angles. For this model, the linear polarization varies by

, the polarization position angle varies by

, the ΔV magnitude varies up to 0.35 mag, and the Δ(B–V) color varies by up to 0.1 mag. We find that the enhanced disk density models show ranges of polarization and color–magnitudes that are commensurate with what is reported in the literature for all sizes of the density-enhanced regions. From this, we cannot determine any preference for small or large density-enhanced regions.

Published: January 2018

Abstract. Self-anointing behaviour using Bauhinia sp. was reported in
two captive titi monkeys (Callicebus coimbrai and
Callicebus barbarabrownae). The study was carried out from
October 2013 to May 2014 during an experimental study investigating
the gut passage time of these individuals at the Getúlio Vargas
Zoobotanical Park, north-eastern Brazil. Although leaves, petioles
and flowers of Bauhinia contain chemical substances that
could affect the presence of ectoparasites, it is unclear if titi
monkeys demonstrate self-anointing behaviour as a method of
self-medication. However, due to the presence of large glands in
C. coimbrai and C. barbarabrownae chests, and the
high frequency of occurrence observed for the adult male, we
cautiously suggest that the use of Bauhinia may be linked
to olfactory communication.

Tendo como referência a tomada de decisão, visualiza-se a importância das temáticas que envolvem finanças comportamentais, onde o indivíduo é analisado sob a ótica das heurísticas e vieses. Nesse sentido, a análise de redes sociais pode contribuir para ampliar os conhecimentos gerados por esta área, visto que considera as transações baseadas em rede. Para tanto, definiu-se como objetivo geral explorar os temas de finanças comportamentais e análise de redes sociais, identificando possíveis relações, com base em periódicos internacionais da área, durante o período de 2012 a 2016. Utilizou-se uma pesquisa bibliométrica em quatro periódicos internacionais relacionados a pesquisas em finanças comportamentais e análise de redes sociais. Como resultado, pode-se observar que, do total de artigos selecionados pelos termos de busca, vinte e cinco compuseram a amostra, sendo o Journal of Economic Psychology o periódico com mais publicações. Verifica-se que predominaram os artigos realizados de forma conjunta, com três autores, que em alguns casos estão vinculados a instituições e países distintos. Em âmbito do conteúdo dos artigos, visualiza-se temas relacionados a redes e questões sociais e comportamentais, sendo artigos empíricos, em sua maioria com a utilização de pesquisa survey e experimentos, visto tratar-se de aspectos associados a cognição.
Accès à la justice pour protéger l’environnement au Québec : réflexions sur la capacité à agir des particuliers et des groupes environnementaux
Authors: Bélanger Michel , Halley Paule 
Published: January 2018

Bien que les droits à l’environnement et de participation du public sont fréquemment proclamés et font l’objet d’un très large consensus, leur mise en oeuvre demeure bien souvent ardue. Le présent article fait un retour sur l’expérience québécoise eu égard à l’accès à la justice en matière d’environnement, afin de réfléchir au chemin parcouru par les particuliers et les associations de défense de l’environnement et les défis qui leur restent à relever.
Outre les avantages indéniables du recours particulier à l’injonction prévu depuis 1978 aux articles 19.1 à 19.7 de la Loi sur la qualité de l’environnement, les tribunaux ont, dans les litiges de nature environnementale, interprété largement les principes de base du Code de procédure civile relatifs à l’intérêt suffisant pour ester en justice.
Lorsque la nature des enjeux soulevés dans un litige environnemental ne permet pas aux tribunaux de conclure à l’existence d’un intérêt suffisant au sens de l’article 85(1) C.p.c., ils ont régulièrement reconnu cet intérêt aux demandeurs, tant individuellement que par le biais d’associations, en invoquant l’existence de questions de droit public au sens de 85(2) C.p.c. Il en va de même lorsque l’objet du litige porte sur le contrôle de la légalité d’une autorisation environnementale délivrée par le ministre de l’Environnement. En accueillant ces demandes, les tribunaux ont reconnu aux demandeurs le même intérêt pour demander une injonction ordonnant la cessation des activités concernées et ce, sans égard au fait que les demandeurs étaient des associations ou fréquentaient le lieu de l’infraction au sens de l’article 19.3 L.q.e.
Avec le temps, les tribunaux ont donc élargi de façon non négligeable l’accès à la justice des individus et des groupes en reconnaissant leur intérêt à agir dans l’intérêt public pour faire respecter leurs droits à l’environnement, de même qu’en démontrant leur ouverture à réduire certaines des charges financières associées aux recours judiciaires. Usant de leur pouvoir discrétionnaire, les tribunaux ont interprété le droit de manière à permettre aux particuliers et aux associations de participer de manière plus effective à la protection de l’environnement, notamment en se portant à sa défense, au nom de l’intérêt public et du droit de chacun à l’environnement, et à s’assurer d’être saisis de questions importantes, qui autrement échapperaient au forum judiciaire.
Benefits of Strength Training for Elderly Women // Dobrobiti treninga snage za žene treće životne dobi
Authors: Stojanović Marko DM , Drid Patrik , Madić Dejan , Ostojić Sergej M 
Published: January 2018

The aging process is associated with loss of skeletal muscle mass and increase in intramuscular fat, the latter also defined as muscle attenuation. Muscle weakness, termed sarcopenia and dynapenia, is a normal age-related phenomenon, occurring at a rate of 1% to 5% annually from the age of 30. This rate means that given typical patterns of physical activity, a 70-year-old woman could have 50% to 70% less strength than she had at age 30. Contrary to long held beliefs, the muscles of elderly women (i.e. aged 65 years and older) continue to be adaptable, even into the extremes of old age, particularly if their muscles are significantly overloaded during training. Therefore, effective strengthening practices must be employed to maintain the highest level of function and achieve optimal aging in elderly women. Done regularly (2-3 times a week), strength training preserve bone density, independence and vitality with age. In addition, strength training also has the ability to reduce the risk of osteoporosis and the signs and symptoms of numerous chronic diseases such as heart disease, arthritis and type 2 diabetes, while also improving sleep and reducing depression. Finally, though muscle strength has been recognized as an important predictor for reduced functional performance, emerging evidence suggests that muscle power (the product of force time velocity or the rate of performing work) is highly effective to elicit substantial improvements in maximal mechanical muscle function (rapid force generation, muscle power and muscle strength) and in functional performance in old and very old women.

AbstractThe inability of the heart to recover from an ischemic insult leads to the formation of fibrotic scar tissue and heart failure. From the therapeutic strategies under investigation, cardiac regeneration holds the promise of restoring the full functionality of a damaged heart. Taking into consideration the presence of vast numbers of fibroblasts and myofibroblasts in the injured heart, direct fibroblast reprogramming into cardiomyocytes using small drug molecules is an attractive therapeutic option to replenish the lost cardiomyocytes. Here, a spermine‐acetalated dextran‐based functional nanoparticle is developed for pH‐triggered drug delivery of two poorly water soluble small molecules, CHIR99021 and SB431542, both capable of increasing the efficiency of direct reprogramming of fibroblast into cardiomyocytes. Upon functionalization with polyethylene glycol and atrial natriuretic peptide, the biocompatibility of the nanosystem is improved, and the cellular interactions with the cardiac nonmyocytes are specifically augmented. The dual delivery of the compounds is verified in vitro, and the compounds exerted concomitantly anticipate biological effects by stabilizing β‐catenin (CHIR99021) and by preventing translocation of Smad3 to the nucleus of (myo)fibroblasts (SB431542). These observations highlight the potential of this nanoparticle‐based system toward improved drug delivery and efficient direct reprogramming of fibroblasts into cardiomyocyte‐like cells, and thus, potential cardiac regeneration therapy.
Interfacial Mineral Fusion and Tubule Entanglement as a Means to Harden a Bone Augmentation Material

Published: January 2018

AbstractA new bone augmenting material is reported, which is formed from calcium‐loaded hydrogel‐based spheres. On immersion of these spheres in a physiological medium, they become surrounded with a sheath of precipitate, which ruptures due to a build‐up in osmotic pressure. This results in the formation of mineral tubes that protrude from the sphere surface. When brought into close contact with one another, these spheres become fused through the entanglement and subsequent interstitial mineralization of the mineral tubules. The tubular calcium phosphate induces the expression of osteogenic genes (runt‐related transcription factor 2 (RUNX2), transcription factor SP7 (SP7), collagen type 1 alpha 1 (COL1A1), and bone gamma‐carboxyglutamic acid‐containing protein (BGLAP)) and promotes the formation of mineral nodules in preosteoblast cultures comparable to an apatitic calcium phosphate phase. Furthermore, alkaline phosphatase (ALP) is significantly upregulated in the presence of tubular materials after 10 d in culture compared with control groups (p < 0.001) and sintered apatite (p < 0.05). This is the first report of a bioceramic material that is formed in its entirety in situ and is therefore likely to provide a better proxy for biological mineral than other existing synthetic alternatives to bone grafts.
Uptake and Intracellular Fate of Engineered Nanoparticles in Mammalian Cells: Capabilities and Limitations of Transmission Electron Microscopy—Polymer‐Based Nanoparticles
Authors: Reifarth Martin , Hoeppener Stephanie , Schubert Ulrich S. 
Published: January 2018

AbstractIn order to elucidate mechanisms of nanoparticle (NP)–cell interactions, a detailed knowledge about membrane–particle interactions, intracellular distributions, and nucleus penetration capabilities, etc. becomes indispensable. The utilization of NPs as additives in many consumer products, as well as the increasing interest of tailor‐made nanoobjects as novel therapeutic and diagnostic platforms, makes it essential to gain deeper insights about their biological effects. Transmission electron microscopy (TEM) represents an outstanding method to study the uptake and intracellular fate of NPs, since this technique provides a resolution far better than the particle size. Additionally, its capability to highlight ultrastructural details of the cellular interior as well as membrane features is unmatched by other approaches. Here, a summary is provided on studies utilizing TEM to investigate the uptake and mode‐of‐action of tailor‐made polymer nanoparticles in mammalian cells. For this purpose, the capabilities as well as limitations of TEM investigations are discussed to provide a detailed overview on uptake studies of common nanoparticle systems supported by TEM investigations. Furthermore, methodologies that can, in particular, address low‐contrast materials in electron microscopy, i.e., polymeric and polymer‐modified nanoparticles, are highlighted.
