Manejo de Identidades en Sistemas P2P Basado en DHT
Authors: Villanueva Ricardo 
Published: August 2017

Este artículo presenta las redes P2P, donde se analizara la manera en la cual los nodos se relacionan entre sí y de que forma en la cual se distribuyen al entrar a la red. Cada nodo al crear una red o unirse a una ya existente posee un identificador el cual da origen a la manera en la que se distribuyen los siguientes nodos que se unirán a la red, la falla radica en que uno de los nodos ya enlazados a la red existente pueden ser maliciosos y originar puntos de ataque a la red afectando la confidencialidad de la información distribuida entre los demás nodos de la red o modificar el enrutamiento de la información suministrada a través de la capa de aplicación, ya que estos nodos solo con el hecho de estar en la red son responsables de la comunicación que se realiza entre ciertos nodos localizados en el anillo. Se indicaran detalladamente los procesos de conexión, comunicación y estabilización de los nodos por medio de la simulación de las redes P2P en ovelay weaver, mostrando consigo las características y resultados de la simulación. AbstractThis paper contains information relating to what concerns the networks P2P, there was analyzed the way in which the nodes relate between yes and of which it forms the organization in which they are distributed on having entered to the network. Every node on having created a network or to join the already existing one possesses an identifier which gives origin to the way in which there are distributed the following nodes that will join the network, The fault takes root in that one of the nodes already connected to the existing network they can be malicious and in originating points of assault to the network affecting the confidentiality of the information distributed between other nodes of the network or to modify the routing of the information supplied across the cap of application, since these nodes only with the fact of being in the network are responsible for the communication that is realized between certain nodes located in the ring. Were indicated detailed the processes of connection, communication and stabilization of the nodes by means of the simulation of the networks P2P in overlay weaver, showing I obtain the characteristics and results of the simulation.

Music in the NICU: The Role of Nurses in Neuroprotection
Authors: Detmer Michael R. , Whelan Madison L. 
Published: August 2017

AbstractEarly exposure to age-appropriate, meaningful auditory stimuli, such as lullaby singing, has been shown to advance various medical and developmental goals in premature infants in the NICU while reducing medical costs. A primary goal of NICU music therapists is to control auditory stimuli in the unit to help premature infants reach the greatest possible sedation. In hospitals with limited or no NICU music therapy (NICU-MT) coverage, nurses and other NICU staff can play an important role in providing neuroprotection to these premature infants while also optimizing neurodevelopment via use of recorded music. Based on current literature, this article provides a set of evidence-based guidelines for the use of recorded music with premature infants.

<p>The evolution of technology has made communication much easier. The existence of recent sophisticated platforms, operating systems, and apps has changed the way people communicate. This is supported by McLuhan’s statement about the determinism theory of technology which in his 1962 book ‘<em>The Guttenberg Galaxy: The Making of Thypographic Man’ </em>declared<em> </em>that technology affects the way people communicate<em> </em> (Straubhaar, Larose, &amp; Davenport, 2010). In this modern era, the evolution of technology has brought the communication amongs celebrities, fans, and haters to the next level. Through social media programs such as Instagram, a celebrity just need post a picture or a video to give an update about their activities for the followers. However, their followers are not just their lovers or fans but their haters as well. Instagram as a social media platform offers a cyber space which enables cyber societies to interact freely. However, this cyber space also allows haters to exist on social media.</p><p>BAHASA INDONESIA ABSTRAK: Kemajuan teknologi mempermudah komunikasi antar manusia.

Pada era modern ini kemajuan teknologi mempermudah komunikasi antar selebriti dan fans melalui media sosial, khususnya Instagram. Dimana melalui Instagram seorang idola atau selebriti cukup memposting sebuah foto atau video di Instagram untuk bertegur sapa dengan para penggemarnya. Namun pada kenyataanya tidak hanya komentar positif yang didapat oleh seorang idola namun juga kritikan pedas dari para haters. Dengan mudahnya akses komunikasi dan Instagram sebagai <em>cyber space</em> yang menjadi ruang berinteraksi antar individu secara bebas pada modern ini melahirkan dampak negatif bagi para selebriti yaitu dengan lahirnya akun-akun <em>haters</em> di media sosial.</p>

Ocena właściwości antyoksydacyjnych liści Ginkgo biloba L. po zakończeniu wegetacji
Authors: Nowak Anna 
Published: August 2017

Wstęp: Miłorząb japoński (Ginkgo biloba L.) jest uważany za cenną roślinę wykazującą działanie przeciwrodnikowe. Związane jest to m.in. z zawartością takich substancji aktywnych, jak polifenole, terpenoidy i witaminy. W celach leczniczych wykorzystuje się ekstrakty z liści, które stosowane są m.in. w profilaktyce chorób cywilizacyjnych. Celem badań było określenie aktywności antyoksydacyjnej wyciągów alkoholowych z suszonych liści miłorzębu japońskiego, opadłych z drzew po zakończonej wegetacji, które najczęściej są materiałem odpadowym.Materiały i metody: Surowiec roślinny stanowiły świeżo zebrane oraz suszone liście miłorzębu japońskiego. Ekstrakty do analiz przygotowano z wykorzystaniem aparatu Soxhleta, wytrząsarki rotacyjnej oraz łaźni ultradźwiękowej. Jako rozpuszczalnik zastosowano etanol oraz metanol. Zdolność do eliminowania wolnych rodników (radical scavenging activity – RSA) oznaczono metodą z użyciem odczynnika DPPH (2,2-difenylo-1-pikrylohydrazyl), natomiast całkowitą zawartość polifenoli metodą Folina–Ciocalteu’a.Wyniki: Aktywność antyoksydacyjna wyciągów z suchych liści miłorzębu mieściła się w granicach od 37,69 ±1,97 do 92,85 ±0,28% RSA, przy czym najwyższy wynik uzyskano w grupie ekstraktów w 40% (v/v) etanolu. Spośród wyciągów w 70% (v/v) etanolu najwyższymi wartościami RSA% charakteryzowały się liście ekstrahowane za pomocą wytrząsarki (92,37 ±0,84% RSA), natomiast w przypadku zastosowania 96% (v/v) etanolu – ekstrakty pochodzące z aparatu Soxhleta (81,71 ±2,10%). Duże zdolności przeciwutleniające wykazywały również wyciągi metanolowe. Do ich otrzymania wykorzystano wytrząsarkę i uzyskano wynik wynoszący 89,25 ±0,54% RSA. Najwyższą ogólną zawartość polifenoli odnotowano w próbach ekstrahowanych w aparacie Soxhleta (etanol 40%), w których zawartość wynosiła 9,15 mg/g surowca. Wykazano również dodatnią korelację pomiędzy ogólną zawartością polifenoli a aktywnością antyoksy­dacyjną wyrażoną w % RSA analizowanych prób.Wnioski: Wyciągi z żółtych liści miłorzębu japońskiego zebranych po zakończonej wegetacji charakteryzują się dużą zdolnością zmiatania wolnych rodników, co sugeruje możliwość wykorzystania tego materiału odpadowego jako cennego źródła antyoksydantów.
Tiltmeter Mapping of Measured Nonsymmetric Hydraulic-Fracture Growth in a Conglomerate/Sandstone Formation Using the Implicit Level-Set Algorithm and the Extended Kalman Filter

Published: August 2017

SummaryA novel method to map asymmetric hydraulic-fracture propagation using tiltmeter measurements is presented. Hydraulic fracturing is primarily used for oil-and-gas well stimulation, and is also applied to precondition rock before mining. The geometry of the developing fracture is often remotely monitored with tiltmeters—instruments that are able to remotely measure the fracture-induced deformations. However, conventional analysis of tiltmeter data is limited to determining the fracture orientation and volume. The objective of this work is to detect asymmetric fracture growth during a hydraulic-fracturing treatment, which will yield height-growth information for vertical fracture growth and horizontal asymmetry for lateral fracture growth or detect low preconditioning-treatment efficiency in mining. The technique proposed here uses the extended Kalman filter (EKF) to assimilate tilt data into a hydraulic-fracture model to track the geometry of the fracture front. The EKF uses the implicit level set algorithm (ILSA) as the dynamic model to locate the boundary of the fracture by solving the coupled fluid-flow/fracture-propagation equations, and uses the Okada half-space solution as the observation model (forward model) to relate the fracture geometry to the measured tilts. The 3D fracture model uses the Okada analytical expressions for the displacements and tilts caused by piecewise constant-displacement discontinuity elements to discretize the fracture area. The proposed technique is first validated by a numerical example in which synthetic tilt data are generated by assuming a confining-stress gradient to generate asymmetric fracture growth. The inversion is carried in a two-step process in which the fracture dip and dip direction are first obtained with an elliptical fracture-forward model, and then the ILSA-EKF model is used to obtain the fracture footprint by fixing the dip and dip direction to the values obtained in the first step. Finally, the ILSA-EKF scheme is used to predict the fracture width and geometry evolution from real field data, which are compared with intersection data obtained by temperature and pressure monitoring in offset boreholes. The results show that the procedure is able to satisfactorily capture fracture growth and asymmetry even though the field data contain significant noise, the tiltmeters are relatively far from the fracture, and the dynamic model contains significant “unmodeled dynamics” such as stress anisotropy, material heterogeneity, fluid leakoff into the formation, and other physical processes that have not been explicitly accounted for in the dynamic ILSA model. However, all the physical processes that affect the tilt signal are incorporated by the EKF when the tilt measurements are used to obtain the maximum likelihood estimates of the fracture widths and geometry.
Separation of emulsified crude oil in saline water by flotation with micro- and nanobubbles generated by a multiphase pump
Authors: Oliveira H. A. , Azevedo A. C. , Etchepare R. , Rubio J. 
Published: August 2017

Abstract
The flocculation–column flotation with hydraulic loading (HL, &gt;10 m h−1) was studied for the treatment of oil-in-water emulsions containing 70–400 mg L−1 (turbidity = 70–226 NTU) of oil and salinity (30 and 100 g L−1). A polyacrylamide (Dismulgan, 20 mg L−1) flocculated the oil droplets, using two floc generator reactors, with rapid and slow mixing stages (head loss = 0.9 to 3.5 bar). Flotation was conducted in two cells (1.5 and 2.5 m) with microbubbles (MBs, 5–80 μm) and nanobubbles (NBs, 50–300 nm diameter, concentration of 108 NBs mL−1). Bubbles were formed using a centrifugal multiphase pump, with optimized parameters and a needle valve. The results showed higher efficiency with the taller column reducing the residual oil content to 4 mg L−1 and turbidity to 7 NTU. At high HL (27.5 m h−1), the residual oil concentrations were below the standard emission (29 mg L−1), reaching 18 mg L−1. The best results were obtained with high concentration of NBs (apart from the bigger bubbles). Mechanisms involved appear to be attachment and entrapment of the NBs onto and inside the flocs. Thus, the aggregates were readily captured, by bigger bubbles (mostly MBs) aiding shear withstanding. Advantages are the small footprint of the cells, low residence time and high processing rate.
Evaluation of nutrient retention in vegetated filter strips using the SWAT model
Authors: Elçi Alper 
Published: August 2017

Abstract
Nutrient fluxes in stream basins need to be controlled to achieve good water quality status. In stream basins with intensive agricultural activities, nutrients predominantly come from diffuse sources. Therefore, best management practices (BMPs) are increasingly implemented to reduce nutrient input to streams. The objective of this study is to evaluate the impact of vegetated filter strip (VFS) application as an agricultural BMP. For this purpose, SWAT is chosen, a semi-distributed water quality assessment model that works at the watershed scale, and applied on the Nif stream basin, a small-sized basin in Western Turkey. The model is calibrated with an automated procedure against measured monthly discharge data. Nutrient loads for each sub-basin are estimated considering basin-wide data on chemical fertilizer and manure usage, population data for septic tank effluents and information about the land cover. Nutrient loads for 19 sub-basins are predicted on an annual basis. Average total nitrogen and total phosphorus loads are estimated as 47.85 t/yr and 13.36 t/yr for the entire basin. Results show that VFS application in one sub-basin offers limited retention of nutrients and that a selection of 20-m filter width is most effective from a cost–benefit perspective.
Survival and Antibiotic Resistance of Bacteria in Artificial Snow Produced from Contaminated Water

Published: August 2017

ABSTRACT: This study shows microbiological contamination of water in two main Podhale rivers, whose resources are used for the production of artificial snow, and the resulting snow contamination. Thirty‐one E. coli strains were isolated from snow at two ski stations in the studied region, their antimicrobial resistance was determined, and the presence of extended spectrum β‐lactamase (ESBL) genes was searched for. The results indicate that the waters of both rivers are severely contaminated, resulting in the contamination of artificial snow with, among others, thermotolerant E. coli. E. coli isolated from snow were most frequently resistant to ampicillin (74.19%) and amoxicillin/clavulanate (51.61% isolates). Aminoglycosides and third generation cephalosporins were most efficient among the tested antimicrobials. Some bacterial strains were multidrug resistant and three strains exhibited the ESBL mechanism. Molecular analyses showed the presence of ESBL genes in the same three strains. Genetic variation among E. coli indicates that only some genotypes are able to survive the artificial snow production process.
Peer Communication in Online Mental Health Forums for Young People: Directional and Nondirectional Support
Authors: Prescott Julie , Hanley Terry , Ujhelyi Katalin 
Published: August 2017

Background
The Internet has the potential to help young people by reducing the stigma associated with mental health and enabling young people to access services and professionals which they may not otherwise access. Online support can empower young people, help them develop new online friendships, share personal experiences, communicate with others who understand, provide information and emotional support, and most importantly help them feel less alone and normalize their experiences in the world.

Objective
The aim of the research was to gain an understanding of how young people use an online forum for emotional and mental health issues. Specifically, the project examined what young people discuss and how they seek support on the forum (objective 1). Furthermore, it looked at how the young service users responded to posts to gain an understanding of how young people provided each other with peer-to-peer support (objective 2).

Methods
Kooth is an online counseling service for young people aged 11-25 years and experiencing emotional and mental health problems. It is based in the United Kingdom and provides support that is anonymous, confidential, and free at the point of delivery. Kooth provided the researchers with all the online forum posts between a 2-year period, which resulted in a dataset of 622 initial posts and 3657 initial posts with responses. Thematic analysis was employed to elicit key themes from the dataset.

Results
The findings support the literature that online forums provide young people with both informational and emotional support around a wide array of topics. The findings from this large dataset also reveal that this informational or emotional support can be viewed as directive or nondirective. The nondirective approach refers to when young people provide others with support by sharing their own experiences. These posts do not include explicit advice to act in a particular way, but the sharing process is hoped to be of use to the poster. The directive approach, in contrast, involves individuals making an explicit suggestion of what they believe the poster should do.

Conclusions
This study adds to the research exploring what young people discuss within online forums and provides insights into how these communications take place. Furthermore, it highlights the challenge that organizations may encounter in mediating support that is multidimensional in nature (informational-emotional, directive-nondirective).

Protein-energy malnutrition is the most widespread nutritional deficiency disorder in India, commonly occurring in children aged 6 months-2 years,as per the National Family Health Survey, 2007. The dermatologic manifestations are more florid and characteristic in kwashiorkor than in marasmus.Here, we present a case of a 1½ years old male, with extensive skin lesions, owing to severe malnutrition. Malnourishment is one of the foremostconditions seen in the developing countries. It is essential to provide adequate nutritional support to the growing children and to impart proper education to the mothers with regard to weaning and care during the illness of children aged under 5 years.
