Authors: Sugiartha I Wayan , Rofaida Aryani 
Published: October 2018

Kekuatan sambungan bambu salah satunya ditentukan oleh jarak ujung alat sambung. Jarak ujung alat sambung sangat penting untuk diperhatikan pada sambungan bambu dengan baut karena bambu yang berbentuk tubular dan mempunyai gaya geser sejajar serat yang rendah. Kendala tersebut dapat diatasi dengan memberi pengisi disekitar lubang sambungan. Namun demikian, efektifitas dari bambu berpengisi yang diberi celah untuk menempatkan pelat buhul pada sambungan perlu dikaji lebih lanjut. Tujuan dari penelitian ini adalah untuk mengetahui kuat tarik sambungan bamboo celah berpengisi dengan alat sambung baut pada berbagai variasi jarak ujung dan mengetahui pola kegagalan sambungan. Lima variasi benda uji dibuat dengan jarak ujung masing-masing sebesar 50 mm, 60 mm, 70 mm, 80 mm dan 90 mm. Pengujian benda uji dilakukan pada load frame dan pembebanan diberikan secara bertahap melalui hydaulic jack sampai terjadi kegagalan. Hasil pengujian menunjukkan bahwa kuat tarik sambungan meningkat seiring dengan meningkatnya jarak ujung alat sambung. Kuat tarik maksimum yang dihasilkan pada variasi jarak ujung50 mm, 60 mm, 70 mm, 80 mm dan 90 mm berturut-turut sebesar 1997, 352 Kg, 2124, 36 Kg, 2336, 04 Kg, 2381, 4 Kg, dan 2411, 64 Kg dengan prosentase kenaikan berkisar sebesar 6%, 17%, 19%, dan 21%. Pola kegagalan yang terjadi pada seluruh benda uji relatif sama yaitu baut tertekuk atau patah.
Essai de détermination de l'âge géologique à partir des distances réticulaires et des propriétés optiques des allanites radioactives (I)
Authors: Pellas Paul 
Published: October 2018

Dans la première partie de cette étude, après avoir envisagé tous les facteurs d'erreur (différences de composition chimique, altérations, recristallisations métamorphiques, etc...) qui pourraient rendre problématiques les déterminations d'âge, on montre que dans de nombreux exemples il est possible d'établir une relation entre l'accroissement de certains intervalles réticulaires et les doses d'irradiation reçues par les allanites. Cette relation, matérialisée en une courbe, permet d'obtenir des âges apparents valables bien qu'approximatifs. Ces âges apparents se rapprochent des âges absolus ou stratigraphiques toutes les fois où un métamorphisme ultérieur n'a pas exercé son influence, auquel cas l'âge apparent date la dernière manifestation métamorphique.
Dans la deuxième partie on montrera que dans la mesure où le pléochroïsme et la biréfringence des allanites requièrent pour s'annuler des doses d'irradiation pré¬ cises, celles-ci peuvent être utilisées pour définir des âges maximaux et minimaux qui, dans certains cas favorables, permettent de délimiter un intervalle de temps correspondant à l'âge apparent.

Abstract
We present a new precision measurement of gas-phase abundances of S, O, N, Si, Fe, P, Al, Ca as well as molecular hydrogen (H2) in the Leading Arm (region II, LA II) of the Magellanic Stream (MS) toward the Seyfert galaxy NGC 3783. The results are based on high-quality archival ultraviolet/optical/radio data from various different instruments (HST/STIS, FUSE, AAT, GBT, GB140 ft, ATCA). Our study updates previous results from lower-resolution data and provides for the first time a self-consistent component model of the complex multiphase absorber, delivering important constraints on the nature and origin of LA II. We derive a uniform, moderate α abundance in the two main absorber groups at +245 and +190 km s−1 of α/H = 0.30 ± 0.05 solar, a low nitrogen abundance of N/H = 0.05 ± 0.01 solar, and a high dust content with substantial dust depletion values for Si, Fe, Al, and Ca. These α, N, and dust abundances in LA II are similar to those observed in the Small Magellanic Cloud (SMC). From the analysis of the H2 absorption, we determine a high thermal pressure of P/k ≈ 1680 K cm−3 in LA II, in line with the idea that LA II is located in the inner Milky Way halo at a z-height of <20 kpc, where it hydrodynamically interacts with the ambient hot coronal gas. Our study supports a scenario in which LA II stems from the breakup of a metal- and dust-enriched progenitor cloud that was recently (200–500 Myr ago) stripped from the SMC.
A Particle Module for the PLUTO Code. II. Hybrid Framework for Modeling Nonthermal Emission from Relativistic Magnetized Flows

Published: October 2018

Abstract
We describe a new hybrid framework to model non-thermal spectral signatures from highly energetic particles embedded in a large-scale classical or relativistic magnetohydrodynamic (MHD) flow. Our method makes use of Lagrangian particles moving through an Eulerian grid where the (relativistic) MHD equations are solved concurrently. Lagrangian particles follow fluid streamlines and represent ensembles of (real) relativistic particles with a finite energy distribution. The spectral distribution of each particle is updated in time by solving the relativistic cosmic ray transport equation based on local fluid conditions. This enables us to account for a number of physical processes, such as adiabatic expansion, synchrotron and inverse Compton emission. An accurate semi-analytically numerical scheme that combines the method of characteristics with a Lagrangian discretization in the energy coordinate is described. In the presence of (relativistic) magnetized shocks, a novel approach to consistently model particle energization due to diffusive shock acceleration is presented. Our approach relies on a refined shock-detection algorithm and updates the particle energy distribution based on the shock compression ratio, magnetic field orientation, and amount of (parameterized) turbulence. The evolved distribution from each Lagrangian particle is further used to produce observational signatures like emission maps and polarization signals, accounting for proper relativistic corrections. We further demonstrate the validity of this hybrid framework using standard numerical benchmarks and evaluate the applicability of such a tool to study high-energy emission from extragalactic jets.
The ν-Process in the Light of an Improved Understanding of Supernova Neutrino Spectra

Published: October 2018

Abstract
We study the neutrino-induced production of nuclides in explosive supernova nucleosynthesis for progenitor stars with solar metallicity including neutrino-nucleus reactions for all nuclei with charge numbers Z < 76, with average neutrino energies in agreement with modern supernova simulations. Considering progenitors with initial main sequence masses between 13 M
⊙ and 30 M
⊙, we find a significant production of 11B, 138La, and 180Ta by neutrino nucleosynthesis, despite the significantly reduced neutrino energies. The production of 19F turns out to be more sensitive to the progenitor mass and structure than to the ν-process. With our complete set of cross sections we have identified the effects of the ν-process on several stable nuclei including 33S, 40Ar, 41K, 59Co, and 113In at the 10% level. Neutrino-induced reactions contribute to a similar extent to the production of radioactive 26Al and increase the yield of 22Na by 50%. Future γ-ray astronomy missions may reach the sensitivity at which the contribution from the ν-process becomes relevant. We find that the production of 22Na by the ν-process could explain the Ne-E(L) component of meteoritic graphite grains. The ν-process enhances the yield of 36Cl and we point out that the resulting 36Cl/35Cl ratio is in agreement with the values inferred for the early solar system. Our extended set of neutrino-nucleus interactions also allows us to exclude any further effects of the ν-process on stable nuclei and to quantify the effects on numerous, hitherto unconsidered radioactive nuclei, e.g., 36Cl, 72As, 84Rb, and 88Y.
HIV-1 Nef Hijacks Lck and Rac1 Endosomal Traffic To Dually Modulate Signaling-Mediated and Actin Cytoskeleton–Mediated T Cell Functions

Published: October 2018

Abstract
Endosomal traffic of TCR and signaling molecules regulates immunological synapse formation and T cell activation. We recently showed that Rab11 endosomes regulate the subcellular localization of the tyrosine kinase Lck and of the GTPase Rac1 and control their functions in TCR signaling and actin cytoskeleton remodeling. HIV-1 infection of T cells alters their endosomal traffic, activation capacity, and actin cytoskeleton organization. The viral protein Nef is pivotal for these modifications. We hypothesized that HIV-1 Nef could jointly alter Lck and Rac1 endosomal traffic and concomitantly modulate their functions. In this study, we show that HIV-1 infection of human T cells sequesters both Lck and Rac1 in a pericentrosomal compartment in an Nef-dependent manner. Strikingly, the Nef-induced Lck compartment contains signaling-competent forms (phosphorylated on key Tyr residues) of Lck and some of its downstream effectors, TCRζ, ZAP70, SLP76, and Vav1, avoiding the proximal LAT adaptor. Importantly, Nef-induced concentration of signaling molecules was concomitant with the upregulation of several early and late T cell activation genes. Moreover, preventing the concentration of the Nef-induced Lck compartment by depleting the Rab11 effector FIP3 counteracted Nef-induced gene expression upregulation. In addition, Nef extensively sequesters Rac1 and downregulates Rac1-dependent actin cytoskeleton remodeling, thus reducing T cell spreading. Therefore, by modifying their endosomal traffic, Nef hijacks signaling and actin cytoskeleton regulators to dually modulate their functional outputs. Our data shed new light into the molecular mechanisms that modify T cell physiology during HIV-1 infection.

Published: October 2018

ABSTRACTThe aim of this consensus conference was to provide clinical guidelines, based on the available evidence and on the author's daily practice and experience, for general dentistry and dental practitioners to allow them to delivery long-term successful restorations. Three groups of expert clinicians and dental technicians were invited to evaluate all of the scientific literature from 1967 up to March 2017 to identify relevant studies on assigned topics and to prepare in advance narrative/systematic review, written according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, to fulfill the consensus statement criteria. The three topics assigned to the three groups were abutment/framework materials and customization (metal vs. metal-free restorations), abutment/framework protocols and designs, and abutment/framework retentions (cemented- vs. screw-retained implant-supported prostheses). All the expert clinicians presented their results, and the lectures were followed by discussions. No significant differences in clinical parameters (marginal bone loss, bleeding on probing, and pocket probing depth) between screw- or cemented-retained were found for single and multiple implant-supported restorations. There is moderate evidence that nonoriginal abutments provide worse mechanical behavior than originals and high evidence that different implant neck designs do not offer any clinical or radiographic advantage. All the participants agreed that it is desirable to connect and remove abutments as few times as possible. There is medium evidence that an adequate platform switching tends to enhance tissue volume and stability in the medium- and long-term follow-up. No statistically significant differences exist between metal and zirconia as a framework material. The authors discussed and all agreed that retrievability and patient's expectation (function and esthetics) should guide the choice of the most adequate technique, component, and material.

Published: October 2018

ABSTRACT
Objectives: The objective is to know the extent of agreement of clinicians' perception of nasolabial esthetic compared to that of laypeople (parents). Materials and Methods: This was a prospective study of comparison of clinician's perception of nasolabial esthetics with that of laypeople following surgical repair of UCL. Participants were recruited from the Cleft Clinic of the Lagos University Teaching Hospital, and surgical repair of the cleft was performed under general anesthesia. Surgical evaluation was done through direct clinical evaluation using the modified form of the Christofides' criteria by laypeople and professionals. Results: A total of 48 cleft participants were enrolled in the study. The evaluation of the lip by both the laypeople and professionals was similar, and there was no difference (0.588) in their rating. However, there was a significant disagreement (P = 0.001) between them in the nose assessment. Conclusion: Neither the solitary opinion of the professionals nor that of the laypeople is satisfactory in the evaluation of facial esthetics; both are equally important, especially in the assessment of nasal esthetics. However, opinion of either the laypeople or the professional might be enough in the evaluation of the lip esthetics.

Buscou-secompreender as necessidades de saúde de familiares de usuários de substâncias psicoativas(SPA). Pesquisa descritiva realizada com familiares dos usuários acompanhados em um Centro de Atenção Psicossocial, cujos dados foram produzidos por meio de entrevistas. Após análise de conteúdo identificaram-se categorias: necessidade de saúde como doença localizada no corpo biológico, necessidade de saúde como reprodução social e necessidade de saúde centrada nas relações e no cuidado. As necessidades de saúde são percebidas como necessidade de cuidado com corpo, mente e espírito. O que não se manifesta por meio de sinais e sintomas nem sempre é reconhecido. Identificou-se tendência em não reconhecer formas de adoecer oriundas do convívio com os usuários de SPA. Há uma demanda de compartilhar problemas com pessoas dispostas a escutar, sejam profissionais ou não. Os profissionais devem estar atentos a estas necessidades que podem implicar no esquecimento dos cuidados com a própria saúde por parte dos familiares.
Redesigning an Information System that Reduces Health Care Accessibility Effort and
Increases User Acceptance and Satisfaction: A Comparative Effectiveness Study
Authors: Long Sandra , Monsen Karen A. , Pieczkiewicz David , Wolfson Julian , Khairat Saif 
Published: October 2018

Objectives: This research tackles a critical issue in modern health care
systems—namely, to determine if creating a user-centered health information system that
is easy to utilize would lead to consumers who are more satisfied and more likely to
accept the system. Materials and Methods: The health information system is a consumer
service center that receives inquiries from consumers on how to find and pay for care.
To understand if a system designed to decrease effort results in satisfaction, we
redesigned the system, deployed it for 3 months, and then compared consumer satisfaction
results to a control group. Satisfaction and Net Promoter surveys were provided to
consumers who used the control system and consumers using the redesigned system.Results:
This study was completed over a 6 month continual time period where over 100,000
consumer interactions took place. Using 11 different metrics and data from over 5,000
random system users, it was shown that consumers were more satisfied with an information
system designed to reduce their administrative effort. Discussion: While not all
consumer survey results were statistically significant, they all showed a shift towards
improved satisfaction with the health care system. Statistically, it was shown that
there was a dependency between the design of the system to provide information and many
needs of the consumers. Conclusion: A health care system designed to reduce effort in
accessing care results in improved consumer satisfaction. Consumers are also more likely
to trust the assistance provided by the organization.
