Published: August 2018

Microfluidics devices have been applied in the biomedical field to manipulate the tissue fluids in channels with dimensions between 5-500 lm. Microfluidics device manufactured by a microfabrication process consisting of design, microstucturing and back-end processes. One application of microfluidics is a passive mixing microchannel. In this device, the liquid will flow through the channel without any moving parts and the pressure from the outside to produce a fluid mixing. It is important to design the shape of the channel to generate a nice passive mixing microchannel. Low power CO2 laser is used to process microstucturing as cutting tools to produce microfluidic devices on acyilic material. Surface roughness lines were designed to be observed. In this study, the design process channel carried by the experimental method through the parameters that affect the output of the process is the power of laser cutting, cutting speed and design channel. And then the fabrication of microfluidics with back-end processing is done by the process of merging with a thermal bonding method. Finally, From the experimental results, the design of the channel 1 has an influence on all the parameters for surface roughness compared with a channel design 2.

Published: August 2018

In order to design reusable processes by structuring and designing activities for teams of people through Collaboration Engineering, the Research and Development Group in Software Engineering (IDIS) of the University of Cauca, has proposed the model ChildProgramming-C, which seeks to make a contribution from the Collaborative Engineering approach to the ChildProgramming Software development model. In the progress of the investigation two exploratory case studies have been carried out with children of an Educational institution, where it was evidenced that in spite of theoretically proposing collaborative activities for children to learn to develop software, during practice there are situations that do not guarantee positive interdependence, individual responsibility and equal participation, as fundamental characteristics of collaborative work. Therefore, a preliminary phase is proposed to the Childprogramming model, which seeks to sensitize children about the importance of collaboration by being part of a team, through ludic strategies, allowing the development of social, cognitive and computational thinking skills. This article shows the experience of the sensitization phase and the evaluation through the application of a confi rmatory case study.

Published: August 2018

Salah satu permasalahan dalam pembelajaran Bahasa Indonesia adalah rendahnya aktivitas dan hasil belajar siswa. Sebagai salah satu alternatif untuk mengatasi permasalahan tersebut adalah dengan pembelajaran kontekstual melalui penggunaan multimedia interaktif model simulasi dalam pembelajaran bahasa Indonesia. Menurut Hull’s dan Sounders (Komalasari, 2010: 6) “Di dalam pembelajaran kontekstual, siswa menemukan hubungan penuh makna antara ide-ide abstrak dengan penerapan praktis di dalam konteks dunia nyata. Siswa menginternalisasi konsep melalui penemuan, penguatan, dan keterhubungan.” Selain itu, menurut Sanjaya (2012: 206-210) fungsi dan manfaat penggunaan media pembelajaran antara lain adalah “…berperan untuk: 1) menangkap suatu objek atau peristiwa-peristiwa tertentu; 2) memanipulasi keadaan, peristiwa, atau objek tertentu; 3) menambah gairah dan motivasi belajar siswa; 4) media pembelajaran memiliki nilai praktis…”. Dengan demikian, penerapan model pembelajaran di atas memungkinkan adanya peningkatan aktivitas dan hasil belajar siswa.
Cerebral Aspergillosis in an Immunocompetent Patient: A Case Report

Published: August 2018

Aspergillus is a fungus found in the environment. In an immunocompetent person, inhalation of spores may cause localized infection. Invasive aspergillosis has a poor prognosis. We describe a case of cerebral aspergillosis in an immune competent patient. A 30-year-old man was admitted with seizures and headaches. Magnetic resonance imaging (MRI) of the brain showed contrast enhancing lesion at the suprasellar region. Excision biopsies showed granulomatous reactions, mixed inflammatory infiltration, fibrosis, and necro-purulent material mixed with fungal hyphae featuring acute-angle branching and septation, which was compatible with aspergillosis. Amphotericin B was begun. The results of testing for human immunodeficiency virus (HIV) was negative. Unfortunately the patient died on twentieth post-operative day. Most cases of invasive aspergillosis show that this organism is pathogenic in immunocompromized patients; however, some case reports show that invasive aspergillosis may not be so rare in immunocompetent patients. In these patients, virulent and drug-resistant forms of Aspergillus may be responsible for the disease, and treatment with antifungal agents is often ineffective, so that surgical excision is required.Bangladesh Journal of Infectious Diseases 2017; 4(2):52-55
The Spatial Distribution of Satellite Galaxies Selected from Redshift Space

Abstract
We investigate the spatial distribution of satellite galaxies using a mock redshift survey of the first Millennium Run simulation. The satellites were identified using common redshift space criteria, therefore the sample includes a large percentage of interlopers. The satellite locations are well fitted by a combination of a Navarro, Frenk and White (NFW) density profile and a power law. At fixed stellar mass, the NFW scale parameter, r

s

for the satellite distribution of blue hosts. In both cases, the dependence of r

, the satellite distribution around blue hosts is more concentrated than is the satellite distribution around red hosts. The spatial distribution of the satellites of red hosts traces that of the hosts’ halos; however, the spatial distribution of the satellites of blue hosts is more concentrated than that of the hosts’ halos by a factor of ∼2. Our methodology is general, and applies to any analysis of satellites in a mock redshift survey. However, our conclusions necessarily depend upon the semi-analytic galaxy formation model that was adopted, and different galaxy formation models may yield different results.

Abstract
We present deep spectroscopic follow-up observations of the Bremer Deep Field (BDF), where the two z ∼ 7 bright Lyα emitters (LAE) BDF521 and BDF3299 were previously discovered by Vanzella et al. and where a factor of ∼3–4 overdensity of faint LBGs has been found by Castellano et al. We confirm a new bright Lyα emitter, BDF2195, at the same redshift of BDF521, z = 7.008 and at only ∼90 kpc physical distance from it, confirming that the BDF area is likely an overdense, reionized region. A quantitative assessment of the Lyα fraction shows that the number of detected bright emitters is much higher than the average found at z ∼ 7, suggesting a high Lyα transmission through the intergalactic medium. However, the line visibility from fainter galaxies is at odds with this finding, as no Lyα emission is found in any of the observed candidates with M
UV > −20.25. This discrepancy can be understood either if some mechanism prevents Lyα emission from fainter galaxies within the ionized bubbles from reaching the observer, or if faint galaxies are located outside the reionized area and bright LAEs are solely responsible for the creation of their own H ii regions. A thorough assessment of the nature of the BDF region and of its sources of re-ionizing radiation will be made possible by James Webb Space Telescope spectroscopic capabilities.

Authors: Ocak Osman Bulut , Inal Asli , Aygit Ebru Demet , Celik Selcen , Ocak Serap Yurttaser , Karabulut Gamze Ozturk , Gokyigit Birsen 
Published: August 2018

Purpose:
To evaluate the outcome of surgical treatment in patients with type 1 monocular elevation deficiency.

Methods:
Patients who were diagnosed as having type 1 monocular elevation deficiency by forced duction test and exaggerated traction test between 2000 and 2016 were retrospectively reviewed. Epidemiologic and clinical features of the patients were noted. The efficacy of ipsilateral inferior rectus recession to vertical misalignments and limitation of elevation were evaluated. The clinical features of the patients who did not achieve surgical success after inferior rectus recession were determined. The surgical and functional results of contralateral superior rectus recession were evaluated for patients who had residual hypotropia under inferior rectus recession.

Results:

Thirty-nine patients were included in the study. Preoperatively, vertical deviations were 20.53 ± 4.50 prism diopters (PD) for near and 22.21 ± 5.12 PD for distance. After inferior rectus recession, the amount of vertical deviation corrected was 15 ± 1.14 PD for near and 17.01 ± 2.00 PD for distance. Ten (25.64%) patients did not achieve surgical success (> 6 PD residual hypotropia). Nine patients (preoperative inferior rectus recession measurements = 28.77 ± 7.25 PD for near and 27 ± 7.44 PD for distance) underwent contralateral superior rectus recession as a second surgery. After contralateral superior rectus recession, 7 of 9 (77.78%) patients achieved surgical success. The limitation of elevation significantly improved after both surgeries (Wilcoxon test,
P
< .05). No diplopia or other complications after surgeries were reported.

Conclusions:
Inferior rectus recession is the first surgical option for patients with type 1 monocular elevation deficiency. Contralateral superior rectus recession is an effective alternative surgical treatment for residual hypotropia after ipsilateral inferior rectus recession.

Light absorption by polar and non-polar aerosol compounds from laboratory biomass combustion
Authors: Sengupta Deep , Samburova Vera , Bhattarai Chiranjivi , Kirillova Elena , Mazzoleni Lynn , Iaukea-Lum Michealene , Watts Adam , Moosmüller Hans , Khlystov Andrey 
Published: August 2018

Abstract. Fresh and atmospherically aged
biomass-burning (BB) aerosol mass is mostly comprised of strongly
light-absorbing black carbon (BC) and of organic carbon (OC) with its
light-absorbing fraction – brown carbon (BrC). There is a lack of data on
the physical and chemical properties of atmospheric BB aerosols, leading to
high uncertainties in estimates of the BB impact on air quality and climate,
especially for BrC. The polarity of chemical compounds influences their fate
in the atmosphere including wet/dry deposition and chemical and physical
processing. So far, most of the attention has been given to the water-soluble
(polar) fraction of BrC, while the non-polar BrC fraction has been largely
ignored. In the present study, the light absorption properties of polar and
non-polar fractions of fresh and aged BB emissions were examined to estimate
the contribution of different-polarity organic compounds to the light
absorption properties of BB aerosols. In our experiments, four globally and regionally important fuels were burned
under flaming and smoldering conditions in the Desert Research Institute
(DRI)
combustion chamber. To mimic atmospheric oxidation processes (5–7 days), BB
emissions were aged using an oxidation flow reactor (OFR). Fresh and OFR-aged
BB aerosols were collected on filters and extracted with water and hexane to
study absorption properties of polar and non-polar organic species. Results
of spectrophotometric measurements (absorption weighted by the solar spectrum
and normalized to mass of fuel consumed) over the 190 to 900 nm wavelength
range showed that the non-polar (hexane-soluble) fraction is 2–3 times more
absorbing than the polar (water-soluble) fraction. However, for emissions
from fuels that undergo flaming combustion, an increased absorbance was
observed for the water extracts of oxidized/aged emissions while the
absorption of the hexane extracts was lower for the aged emissions for the
same type of fuels. Absorption Ångström exponent (AAE) values,
computed based on absorbance values from spectrophotometer measurements, were
changed with aging and the nature of this change was fuel dependent. The
light absorption by humic-like substances (HULIS) was found to be higher in fuels characteristic of the
southwestern USA. The absorption of the HULIS fraction was lower for OFR-aged
BB emissions. Comparison of the light absorption properties of
different-polarity extracts (water, hexane, HULIS) provides insight into the
chemical nature of BB BrC and its transformation during oxidation processes.
Mechanical state of gravel soil in mobilization of rainfall-induced landslides in the Wenchuan seismic area, Sichuan province, China

Published: August 2018

Abstract. Gravel soils generated by the Wenchuan earthquake have
undergone natural consolidation for the past decade. However, geological
hazards, such as slope failures with ensuing landslides, have continued to
pose great threats to the region. In this paper, artificial model tests
were used to observe the changes of soil moisture content and pore water
pressure, as well as macroscopic and microscopic phenomena of gravel soil.
In addition, a mathematical formula of the critical state was derived from
the triaxial test data. Finally, the mechanical states of gravel soil were
determined. The results had five aspects. (1) The time and mode of the
occurrence of landslides were closely related to the initial dry density. The
process of initiation was accompanied by changes in density and void ratio.
(2) The migration of fine particles and the rearrangement of coarse–fine
particles contributed to the reorganization of the microscopic structure,
which might be the main reason for the variation of dry density and void
ratio. (3) If the confining pressure were the same, the void ratios of soils with
constant particle composition would approach approximately critical values.
(4) Mechanical state of gravel soil can be determined by the relative
position between state parameter (e, p′) and ec–p′ planar critical state line,
where e is the void ratio, ec is the critical void ratio and p′ is the
mean effective stress. (5) In the process of landslide initiation,
dilatation and contraction were two types of gravel soil state, but
dilatation was dominant. This paper provided insight into interpreting
landslide initiation from the perspective of critical state soil mechanics.
