Korelasi antara Ankle-Brachial Index, Pulse Oximetry, dan Ankle Peak Systolic Velocity Penderita Diabetes Melitus tanpa Obesitas Abdominal
Authors: Andreas Andreas , Choridah Lina , Sudarmanta Sudarmanta 
Published: March 2019

Background: Diabetes Mellitus is the most common complication of vascular complications, one of which is peripheral arterial disease (PAD), which can increase morbidity and mortality in diabetic patient.Early screening parameter and diagnosis of PAD that currently still largely accepted are Ankle-Brachial Index (ABI) and pulse oximetry. ABI and pulse oximetry each has advantages and disadvantages. Patients with diabetes, especially if accompanied by abdominal obesity often have arterial sti?ness so that the value of ABI actually increased, in this case pulse oximetry has a higher sensitivity. Ankle Peak Systolic Velocity (APSV) which is the average of Peak Systolic Velocity (PSV) of anterior and posterior tibial artery at ankle joint level is a new parameter for assessing ischemia of the lower limb and is not in?uenced by arterial sti?ness. The purpose of this study was to determine and analyze the correlation between ankle-brachial index, pulse oximetry and ankle peak systolic velocity in DM patients without abdominal obesity.Materials and methods: This study was observational analytic with cross-sectional design study in subjects with DM without abdominal obesity who meet the inclusion and exclusion criteria.Results: The subjects consisted of 38 limbs from 19 people, 11 (57.9%) males and 8 (42.1%) women aged 47-68 years. Spearman test showed a positive correlation was signifcant between ABI with APSV (r = 0.549, p <0.001). Correlation between ABI and pulse oximetry; pulse oximetry and APSV showed weak signifcant negative correlation (r = -0.347, p <0.05 and r = -0.369, p <0.05). Only APSV which has a strong positive correlation with clinical PAD signifcantly (r = 0.743, p <0.001).Conclusions: There is no strong correlation between ABI, pulse oximetry and APSV in DM patients without abdominal obesity. APSV can replace ABI and pulse oximetry as a non-invasive examination of diabetic patients for screening and follow-up PAD

Étude diffractométrique de l'évolution thermique du sulfate de rubidium de la température ordinaire jusqu'à 800° C
Authors: Tabrizi Djafar , Pannetier Guy 
Published: March 2019

The variation of the lattice parameters of rubidium sulfate was studied up to 800° C. The caracteristics of the change from orthorhombic to hexagonal symmetry were also studied.
The a parameter increases more than b, and c more than b.
The discontinuities observed for the thermal coefficients for the parameters and the volume show the possible existence of two new low energy transitions at circa 375° C and 575° C and of a new very low energy transition at circa 275° C, besides the polymorphic transition (β ⇆ α) orthorhombic ⇆ hexagonal.
Synthèse sèche d'une smectite fluorée saturée au sodium
Authors: Bordeaux-Juglaret Denise , Roby C. 
Published: March 2019

The conditions of formation and the structural formula of a smectite fluoride (tetrasilicic, trioctahedral fluorosilicate of type 2/1 which undergoes inter-layer hydratation) have been specified. The fluorine, in the synthetic smectite, replaces the hydroxyl group in the corresponding natural mineral.
The smectite was synthesized as the major phase using several starting compositions : a single phase product has not been obtained by synthesis. There are two conditions necessary for the synthesis of a phase with swelling properties : a neutral or reducing environment for the melt and rapid cooling.
X-ray diffraction, chemical studies and infra-red spectroscopy permit the characterisation of the phase. The formula is
Na⁺₁,₈₀ (Mg²⁺₅,₁ Si⁴⁺₈ O²⁻₂₀ F⁻₄)
and measurements of the exchange capacity give the structural formula :
Na⁺₁,₁₀[xii] [(Mg⁺₅,₁ Na⁺₀,₇₀ ⃞₀,₂₀)[vi] (Si⁴⁺₈)[iv] O²⁻₂₀ F⁻₄].
This formula corresponds both to a « fluor-hectorite » and to a « fluorostevensite » by analogy with the natural minerals.
Retired A Stars and Their Companions. VIII. 15 New Planetary Signals around Subgiants and Transit Parameters for California Planet Search Planets with Subgiant Hosts

Published: March 2019

Abstract
We present the discovery of seven new planets and eight planet candidates around subgiant stars, as additions to the known sample of planets around “retired A stars.” Among these are the possible first three-planet systems around subgiant stars, HD 163607 and HD 4917. Additionally, we present calculations of possible transit times, durations, depths, and probabilities for all known planets around subgiant (

) stars, focused on possible transits during the TESS mission. While most have transit probabilities of 1%–2%, we find that there are three planets with transit probabilities >9%.
The Blueshift of the C iv Broad Emission Line in QSOs

Published: March 2019

Abstract
For the sample from Ge et al. of 87 low-z Palomar–Green quasi-stellar objects (QSOs) and 130 high-z QSOs (0 < z < 5) with

-based single-epoch supermassive black hole masses, we perform a uniform decomposition of the C iv
λ1549 broad-line profile. Based on the rest frame defined by the [O iii] λ5007 narrow emission line, a medium-strong positive correlation is found between the C iv blueshift and the luminosity at 5100 Å or the Eddington ratio

. A medium-strong negative relationship is found between the C iv blueshift and C iv equivalent width. These results support the postulation where the radiation pressure may be the driver of C iv blueshift. There is a medium-strong correlation between the mass ratio of C iv-based to

-based

and the C iv blueshift, which indicates that the bias for C iv-based

is affected by the C iv profile.
OH as an Alternate Tracer for Molecular Gas: Quantity and Structure of Molecular Gas in W5
Authors: Engelke Philip D. , Allen Ronald J. 
Published: March 2019

Abstract
We report column densities of molecular gas in the W5 star-forming region as traced with OH 18 cm emission in a grid survey using the Green Bank Telescope. OH appears to trace a greater column density than does CO in 8 out of 15 cases containing OH emission detections; the two molecules trace the same column densities for the other 7 cases. OH and CO trace a similar morphology of molecular gas with a nearly one-to-one correspondence. The mass of molecular gas traced by OH in the portion of the survey containing OH emission is 1.7 (+0.6 or −0.2) × 104
M
⊙, whereas the corresponding CO detections trace 9.9 (±0.7) × 103
M
⊙. We find that for lines observed in absorption, calculations assuming uniform gas and continuum distributions underestimate column density values by one to two orders of magnitude, making them unreliable for our purposes. Modeling of this behavior in terms of OH cloud structure on a scale smaller than telescopic resolution leads us to estimate that the filling factor of OH gas is a few to 10 percent. The total molecular gas content of W5 may be approximately two to three times what we report from direct measurement, because we excluded absorption line detections from the mass estimate.
Environmental Effect on the Interstellar Medium in Galaxies across the Cosmic Web at z = 0.73

Published: March 2019

Abstract
We present new Atacama Large Millimeter Array (ALMA) dust continuum observations of 101

galaxies in the COSMOS field to study the effect of the environment on the interstellar medium at z ∼ 0.7. At this redshift, our targets span a wide range of environments allowing for a diverse sample of galaxies with densities of Σ = 0.16–10.5 Mpc−2 (per Δz = 0.024). Using the ALMA observations, we calculate the total interstellar medium (ISM) mass (M
ISM) and look for depletion as a function of galaxy density in order to understand the quenching or triggering of star formation in galaxies in different environments. M
ISM is found to have a small dependence on the environment, while the depletion timescale remains constant (∼200 Myr) across all environments. We find elevated M
ISM values at intermediate densities and lower values at high densities compared to low (field) densities. Our observed evolution in gas fraction with density in this single redshift slice is equivalent to the observed evolution with cosmic time over 2–3 Gyr. To explain the change in the gas mass fraction seen in galaxies in intermediate and high densities, these results suggest environmental processes such as mergers and ram pressure stripping are likely playing a role in dense filamentary cluster environments.
Central Roles of OX40L–OX40 Interaction in the Induction and Progression of Human T Cell–Driven Acute Graft-versus-Host Disease

Abstract
Graft-versus-host disease (GVHD) is one of the major obstacles for the success of allogeneic hematopoietic stem cell transplantation. In this article, we report that the interaction between OX40L and OX40 is of critical importance for both induction and progression of acute GVHD (aGVHD) driven by human T cells. Anti-human OX40L mAb (hOX40L) treatment could thus effectively reduce the disease severity in a xenogeneic-aGVHD model in both preventative and therapeutic modes. Mechanistically, blocking OX40L–OX40 interaction with an anti-hOX40L reduces infiltration of human T cells in target organs, including liver, gut, lung, and skin. It also decreases IL-21– and TNF-producing T cell responses while promoting regulatory T cell responses without compromising the cytolytic activity of CD8+ T cells. Single blockade of hOX40L was thus more effective than dual blockade of IL-21 and TNF in reducing the severity of aGVHD as well as mortality. Data from this study indicate that OX40L–OX40 interactions play a central role in the pathogenesis of aGVHD induced by human T cells. Therapeutic strategies that can efficiently interrupt OX40L–OX40 interaction in patients might have potential to provide patients with an improved clinical benefit.
Feeding Patterns and Parental Perceptions of Feeding Issues of Preterm Infants in the First 2 Years of Life
Authors: Howe Tsu-Hsin , Sheu Ching-Fan , Wang Tien-Ni 
Published: March 2019

AbstractWe explored parental feeding practices, feeding issues during the first 2 yr of life, and the relationship between feeding issues and levels of maternal distress in preterm infants. Four hundred twenty mothers (239 with preterm infants, 181 with full-term infants) participated in the study. The Behavior-Based Feeding Questionnaire for Infants With Premature History and the Parenting Stress Index–Chinese Version were used as the two outcome measures. The results indicated that preterm infants had different feeding experiences compared with their full-term counterparts. They tended to start solid food later in life and had limited experiences in food variation. Parenting stress was prevalent in parents with preterm infants and was associated with the frequency of feeding issues, especially at later ages when supplementary foods were being introduced.
A novel approach for characterizing the variability in mass–dimension relationships: results from MC3E
Authors: Finlon Joseph A. , McFarquhar Greg M. , Nesbitt Stephen W. , Rauber Robert M. , Morrison Hugh , Wu Wei , Zhang Pengfei 
Published: March 2019

Abstract. Mass–dimension (m–D) relationships determining bulk
microphysical properties such as total water content (TWC) and radar
reflectivity factor (Z) from particle size distributions are used in both
numerical models and remote sensing retrievals. The a and b coefficients
representing m=aDb relationships, however, can vary significantly
depending on meteorological conditions, particle habits, the definition of
particle maximum dimension, the probes used to obtain the data, techniques
used to process the cloud probe data, and other unknown reasons. Thus,
considering a range of a,b coefficients may be more applicable for use in
numerical models and remote sensing retrievals. Microphysical data collected
by two-dimensional optical array probes (OAPs) installed on the University of
North Dakota (UND) Citation aircraft during the Mid-latitude Continental Convective
Clouds Experiment (MC3E) were used in conjunction with TWC data from a
Nevzorov probe and ground-based S-band radar data to determine a and b
using a technique that minimizes the chi-square difference between the TWC and
Z derived from the OAPs and those directly measured by a TWC probe and
radar. All a and b values within a specified tolerance were regarded as equally
plausible solutions. Of the 16 near-constant-temperature flight legs analyzed
during the 25 April, 20 May, and 23 May 2011 events, the derived surfaces of
solutions on the first 2 days where the aircraft-sampled stratiform cloud
had a larger range in a and b for lower temperature environments that
correspond to less variability in N(D), TWC, and Z for a flight leg.
Because different regions of the storm were sampled on 23 May, differences in
the variability in N(D), TWC, and Z influenced the distribution of
chi-square values in the (a,b) phase space and the specified tolerance in a
way that yielded 2.8 times fewer plausible solutions compared to the flight
legs on the other dates. These findings show the importance of representing
the variability in a,b coefficients for numerical modeling and remote
sensing studies, rather than assuming fixed values, as well as the need to
further explore how these surfaces depend on environmental conditions in
clouds containing ice hydrometeors.
Contrasting effects of acidification and warming on dimethylsulfide concentrations during a temperate estuarine fall bloom mesocosm experiment

Published: March 2019

Abstract. The effects of ocean acidification and warming on the concentrations of
dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS) were investigated
during a mesocosm experiment in the Lower St. Lawrence Estuary (LSLE) in the
fall of 2014. Twelve mesocosms covering a range of pHT (pH on the
total hydrogen ion concentration scale) from 8.0 to 7.2, corresponding to a
range of CO2 partial pressures (pCO2) from 440
to 2900 µatm, at two temperatures (in situ and +5 ∘C; 10
and 15 ∘C) were monitored during 13 days. All mesocosms were
characterized by the rapid development of a diatom bloom dominated by
Skeletonema costatum, followed by its decline upon the exhaustion of
nitrate and silicic acid. Neither the acidification nor the warming resulted
in a significant impact on the abundance of bacteria over the experiment.
However, warming the water by 5 ∘C resulted in a significant
increase in the average bacterial production (BP) in all 15 ∘C
mesocosms as compared to 10 ∘C, with no detectable effect of
pCO2 on BP. Variations in total DMSP
(DMSPt = particulate + dissolved DMSP) concentrations
tracked the development of the bloom, although the rise in DMSPt
persisted for a few days after the peaks in chlorophyll a. Average
concentrations of DMSPt were not affected by acidification or
warming. Initially low concentrations of DMS (<1 nmol L−1)
increased to reach peak values ranging from 30 to 130 nmol L−1 towards
the end of the experiment. Increasing the pCO2 reduced the
averaged DMS concentrations by 66 % and 69 % at 10 and
15 ∘C, respectively, over the duration of the experiment. On the
other hand, a 5 ∘C warming increased DMS concentrations by an
average of 240 % as compared to in situ temperature, resulting in a
positive offset of the adverse pCO2 impact. Significant
positive correlations found between bacterial production and concentrations
of DMS throughout our experiment point towards temperature-associated
enhancement of bacterial DMSP metabolism as a likely driver of the mitigating
effect of warming on the negative impact of acidification on the net
production of DMS in the LSLE and potentially the global ocean.
Impact of glacier loss and vegetation succession on annual basin runoff
Authors: Carnahan Evan , Amundson Jason M. , Hood Eran 
Published: March 2019

Abstract. We use a simplified glacier-landscape model to investigate the degree to
which basin topography, climate regime, and vegetation succession impact
centennial variations in basin runoff during glacier retreat. In all
simulations, annual basin runoff initially increases as water is released
from glacier storage but ultimately decreases to below preretreat levels due
to increases in evapotranspiration and decreases in orographic precipitation.
We characterize the long-term (> 200 years) annual basin runoff curves with
four metrics: the magnitude and timing of peak basin runoff, the time to
preretreat basin runoff, and the magnitude of end basin runoff. We find that
basin slope and climate regime have strong impacts on the magnitude and
timing of peak basin runoff. Shallow sloping basins exhibit a later and
larger peak basin runoff than steep basins and, similarly, continental
glaciers produce later and larger peak basin runoff compared to maritime
glaciers. Vegetation succession following glacier loss has little impact on
the peak basin runoff but becomes increasingly important as time progresses,
with more rapid and extensive vegetation leading to shorter times to
preretreat basin runoff and lower levels of end basin runoff. We suggest that
differences in the magnitude and timing of peak basin runoff in our
simulations can largely be attributed to glacier dynamics: glaciers with long
response times (i.e., those that respond slowly to climate change) are pushed
farther out of equilibrium for a given climate forcing and produce larger
variations in basin runoff than glaciers with short response times. Overall,
our results demonstrate that glacier dynamics and vegetation succession
should receive roughly equal attention when assessing the impacts of glacier
mass loss on water resources.
Tertiary Dentine Frequencies in Extant Great Apes and Fossil Hominins
Authors: Towle Ian 
Published: March 2019

Tertiary dentine forms when an odontoblast is directly affected by stimuli, commonly through occlusal wear and caries. In this study the presence of tertiary dentine was recorded in three South African fossil hominin species (Australopithecus africanus, Homo naledi and Paranthropus robustus), and two extant great ape species (Gorilla gorilla gorilla and Pan troglodytes). Frequencies of tertiary dentine were calculated for each species based on macroscopic observations of teeth with dentine exposed through occlusal wear. Overall, the three hominin species have similar tertiary dentine frequencies ranging from 12% to 16.13%. In contrast, over 90% of permanent gorilla teeth with dentine visible show tertiary dentine. Chimpanzees fall between these extremes, with 47.21% of permanent teeth affected. Deciduous teeth follow the same pattern. Species variances are not related to differences in occlusal wear. Instead, some species appear predisposed to produce tertiary dentine earlier/faster, or more often, than other species. Therefore, tertiary dentine formation has the potential to provide useful information on fossil specimens. For example, the uniformly low frequency of tertiary dentine formation in hominins may relate to diet, or be due to thick enamel having a similar role in preventing loss of function of teeth, i.e., extending the life of a tooth. In contrast, tertiary dentine is clearly an important mechanism for normal dental function in gorillas, and may have evolved to help maintain shearing function.
Ibn Shuhayd and his "Risālat al-twābiʿ wa 'l-zawābiʿ"
Authors: Hämeen-Anttila Jaakko 
Published: March 2019

Ibn Shuhayd's (d. 1035) Risālat al-tawābiʿ has been preserved in fragments in Ibn Bassām's al-Dhakhīra. The early eleventh century was a period of great experimentation in narrative prose. Just a few decades before Ibn Shuhayd wrote his work, al-Hamadhānī had written his maqāmas on the other side of the Islamic world. The Risālat al-tawābiʿ comes into the margin of maqāma literature. The original structure of the treatise is reconstructable to a certain extent, especially with the help of al-Thaʿālibī's Yatīmat al-dahr, which has been neglected in earlier studies. In his work, Ibn Shuhayd quotes not only from his own poetry but also from his rasā'il. One of these quotations shows how Ibn Shuhayd himself has revised his original Risālat al-ḥalwā' and modified it to fit it into the new context of the Tawābiʿ.
Openness and Closedness: Four Categories of Closurization in Modern Arabic Fiction
Authors: Taha Ibrahim 
Published: March 2019

The discussion of the four categories of ending and closure in modern Arabic literature in terms of openness and closedness clearly indicates the interrelations between the ending and the model of the textual reality, and the interrelations between this model and the extra-literary reality. It seems that when the historical, and especially the political and the social reality slaps writers across the face and stands before them in all its might and immediacy, they do not remain indifferent and write a literature with optimistic, promising, and closed endings; and vice versa: a text with a model of reality which does not relate to a well defined piece of history ends with a more open type of ending and becomes a closure in the reader.
Reason and Revelation or a Philosopher's Squib (The Sixth Maqāma of Ibn Nāqiyā)
Authors: Kennedy Philip F. 
Published: March 2019

Ibn Nāqiyā (d. 1092) is far less well-known than Badiʿ al-Zamān al-Hamadhānī (d. 1008), creator of the maqāma genre and luminary of the Arabic literary canon. After al-Hamadhānī our attention turns normally to al-Ḥarīrī (d. 1122), who refined certain (mainly linguistic) features of the genre and who has subsequently eclipsed the fame of other authors. Ibn Nāqiyā comes chronologically midway between al-Hamadhānī and al-Ḥarīrī; he amplifies more the irreverent tone than the linguistic register of al-Hamadhānī. The sixth maqāma of Ibn Nāqiyā (one of ten surviving pieces) shows in the author a quite detailed knowledge of falsafa, and from it we sense the growing tension between falsafa and orthodox Sunni theology in the eleventh century C.E. This constitutes more than just the social and discursive backdrop to the text: the dichotomy structures the text whose statement of fatalism is as erudite (in an Aristotelian scheme) as it is facetious - and therefore ultimately incoherent. This article lays bare in a close reading the nature and tone of the parody in this burlesque piece.
