Published: September 2016

We present a detailed analysis of the pre-main-sequence (PMS) population of the young star cluster Westerlund 2 (Wd2), the central ionizing cluster of the H ii region RCW 49, using data from a high-resolution multiband survey with the Hubble Space Telescope. The data were acquired with the Advanced Camera for Surveys in the F555W, F814W, and F658N filters and with the Wide Field Camera 3 in the F125W, F160W, and F128N filters. We find a mean age of the region of 1.04 ± 0.72 Myr. The combination of dereddened F555W and F814W photometry in combination with F658N photometry allows us to study and identify stars with Hα excess emission. With a careful selection of 240 bona-fide PMS Hα excess emitters we were able to determine their Hα luminosity, which has a mean value

. Using the PARSEC 1.2S isochrones to obtain the stellar parameters of the PMS stars, we determined a mean mass accretion rate

per star. A careful analysis of the spatial dependence of the mass accretion rate suggests that this rate is ∼25% lower in the center of the two density peaks of Wd2 in close proximity to the luminous OB stars, compared to the Wd2 average. This rate is higher with increasing distance from the OB stars, indicating that the PMS accretion disks are being rapidly destroyed by the far-ultraviolet radiation emitted by the OB population.

The HD 61005 debris disk (“The Moth”) stands out from the growing collection of spatially resolved circumstellar disks by virtue of its unusual swept-back morphology, brightness asymmetries, and dust ring offset. Despite several suggestions for the physical mechanisms creating these features, no definitive answer has been found. In this work, we demonstrate the plausibility of a scenario in which the disk material is shaped dynamically by an eccentric, inclined planet. We present new Keck NIRC2 scattered-light angular differential imaging of the disk at 1.2–2.3 μm that further constrains its outer morphology (projected separations of 27–135 au). We also present complementary Gemini Planet Imager 1.6 μm total intensity and polarized light detections that probe down to projected separations less than 10 au. To test our planet-sculpting hypothesis, we employed secular perturbation theory to construct parent body and dust distributions that informed scattered-light models. We found that this method produced models with morphological and photometric features similar to those seen in the data, supporting the premise of a planet-perturbed disk. Briefly, our results indicate a disk parent body population with a semimajor axis of 40–52 au and an interior planet with an eccentricity of at least 0.2. Many permutations of planet mass and semimajor axis are allowed, ranging from an Earth mass at 35 au to a Jupiter mass at 5 au.
PROBABILISTIC CROSS-IDENTIFICATION IN CROWDED FIELDS AS AN ASSIGNMENT PROBLEM
Authors: Budavári Tamás , Basu Amitabh
Published: September 2016

One of the outstanding challenges of cross-identification is multiplicity: detections in crowded regions of the sky are often linked to more than one candidate associations of similar likelihoods. We map the resulting maximum likelihood partitioning to the fundamental assignment problem of discrete mathematics and efficiently solve the two-way catalog-level matching in the realm of combinatorial optimization using the so-called Hungarian algorithm. We introduce the method, demonstrate its performance in a mock universe where the true associations are known, and discuss the applicability of the new procedure to large surveys.
A DYNAMIC DENSITY FUNCTIONAL THEORY APPROACH TO DIFFUSION IN WHITE DWARFS AND NEUTRON STAR ENVELOPES
Authors: Diaw A. , Murillo M. S.
Published: September 2016

We develop a multicomponent hydrodynamic model based on moments of the Born–Bogolyubov–Green–Kirkwood–Yvon hierarchy equations for physical conditions relevant to astrophysical plasmas. These equations incorporate strong correlations through a density functional theory closure, while transport enters through a relaxation approximation. This approach enables the introduction of Coulomb coupling correction terms into the standard Burgers equations. The diffusive currents for these strongly coupled plasmas is self-consistently derived. The settling of impurities and its impact on cooling can be greatly affected by strong Coulomb coupling, which we show can be quantified using the direct correlation function.
VARIATIONAL PRINCIPLE FOR PLANETARY INTERIORS
Authors: Zeng Li , Jacobsen Stein B.
Published: September 2016

In the past few years, the number of confirmed planets has grown above 2000. It is clear that they represent a diversity of structures not seen in our own solar system. In addition to very detailed interior modeling, it is valuable to have a simple analytical framework for describing planetary structures. The variational principle is a fundamental principle in physics, entailing that a physical system follows the trajectory, which minimizes its action. It is alternative to the differential equation formulation of a physical system. Applying the variational principle to the planetary interior can beautifully summarize the set of differential equations into one, which provides us some insight into the problem. From this principle, a universal mass–radius relation, an estimate of the error propagation from the equation of state to the mass–radius relation, and a form of the virial theorem applicable to planetary interiors are derived.
DISCOVERY OF TRANSIENT INFRARED EMISSION FROM DUST HEATED BY STELLAR TIDAL DISRUPTION FLARES
Authors: van Velzen S. , Mendez A. J. , Krolik J. H. , Gorjian V.
Published: September 2016

Stars that pass within the Roche radius of a supermassive black hole will be tidally disrupted, yielding a sudden injection of gas close to the black hole horizon which produces an electromagnetic flare. A few dozen of these flares have been discovered in recent years, but current observations provide poor constraints on the bolometric luminosity and total accreted mass of these events. Using images from the Wide-field Infrared Survey Explorer, we have discovered transient 3.4 μm emission from several previously known tidal disruption flares. The observations can be explained by dust heated to its sublimation temperature due to the intense radiation of the tidal flare. From the break in the infrared light curve we infer that this hot dust is located ∼0.1 pc from the supermassive black hole. Since the dust has been heated by absorbing UV and (potentially) soft X-ray photons of the flare, the reprocessing light curve yields an estimate of the bolometric flare luminosity. For the flare PTF-09ge, we infer that the most likely value of the luminosity integrated over frequencies at which dust can absorb photons is

erg s−1, with a factor of 3 uncertainty due to the unknown temperature of the dust. This bolometric luminosity is a factor ∼10 larger than the observed blackbody luminosity. Our work is the first to probe dust in the nuclei of non-active galaxies on sub-parsec scales. The observed infrared luminosity implies a covering factor ∼1% for the nuclear dust in the host galaxies.

Fibromyalgia in Spondyloarthritis: Effect on Disease Activity Assessment in Clinical Practice
Authors: Wach Jean , Letroublon Marie-Claude , Coury Fabienne , Tebib Jacques Guy
Published: September 2016

Objective.

Spondyloarthritis (SpA) is the second most frequent inflammatory rheumatic disease, characterized by spinal involvement, peripheral arthritis, or enthesitis with marked pain, stiffness, and fatigue. Fibromyalgia (FM) may be associated with SpA, and shares some common symptoms. We aimed to determine how FM influences assessment of SpA disease activity, which is mainly dependent on patient-based outcome measures such as the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) or the Ankylosing Spondylitis Disease Activity Score (ASDAS).

Methods.

This single-center cross-sectional study included consecutive patients with SpA according to the Assessment of SpondyloArthritis International Society criteria. FM was diagnosed according to the 1990 American College of Rheumatology criteria. Patient characteristics, BASDAI, ASDAS/C-reactive protein (CRP), Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Metrology Index, and the Medical Outcomes Study Short Form-36 questionnaire were recorded and compared.

Results.

The study included 103 patients with SpA; 81 with axial and 22 with peripheral forms. Eighteen patients presented with concomitant FM, of whom 12 had axial SpA and 6 peripheral SpA. Demographic characteristics did not differ except for sex, with a female predominance in the FM group that was more marked in peripheral forms. BASDAI was higher in patients with FM [median (IQR): 4.2 (4.2) vs 2.2 (3.1); p = 0.0068], whereas ASDAS-CRP was not significantly different [median (IQR): 2.7 (2) vs 2 (1.3); p = 0.1264]. Nevertheless, median ASDAS-CRP corresponded to high disease activity in patients with SpA or FM compared with moderate activity in non-FM patients.

Conclusion.

FM is a frequent comorbidity in patients with SpA, especially in peripheral forms. In patients with SpA-FM, disease activity may be overestimated when measured by BASDAI and to a lesser extent by ASDAS-CRP, and this overestimation could lead to inappropriate treatment escalation.

Published: September 2016

BACKGROUND AND OBJECTIVE:

To determine macular retinal sublayer thickness changes in G11778A Leber hereditary optic neuropathy (LHON).

PATIENTS AND METHODS:

The authors performed a cross-sectional study by segmenting spectral-domain Cirrus OCT (Carl Zeiss Meditec, Dublin, CA) 512 × 128 macular cube scans from a prospective, observational study of G11778A LHON. The thickness of the retinal sublayers of LHON affected subjects and asymptomatic carriers were compared to those of a normal group.

RESULTS:

The study included 20 LHON-affected subjects (13 males; age: 31 years ± 14 years, range: 10 years to 61 years; time since onset of visual loss: 5.9 years ± 8.7 years; 0.4–29.8), 31 asymptomatic LHON carriers (five males; age: 38 years ± 18 years, range: 9 years to 65 years), and 14 normal subjects (five males; age: 39 years ± 13 years, range: 23 years to 61 years). The retinal sublayer thickness parameters were not significantly correlated with age in any of the groups. There were no differences between carriers and normal subjects for thickness of total retina or any sublayer. Affected LHON retinal nerve fiber layer (RNFL) and ganglion cell layer plus inner plexiform layer (GCL+IPL) were thinner, whereas the photoreceptor outer segment (OS) layer was thicker than carriers and normal subjects (
P
values ranged from .042 to < .001), except for the OS layer in the inferior inner ring and temporal outer ring. Differences between groups were not significant in the inner nuclear layer plus outer plexiform layer (INL+OPL). The affected LHON outer nuclear layer plus inner segment layer was thicker in some quadrants, and the affected LHON choroid layer was generally thinner than carriers and normal subjects; however, these differences were not significant after accounting for age.

CONCLUSION:

LHON-affected patients have thickened photoreceptor OS layers in spite of having thinner RNFL and GCL+IPL layers. The findings indicate LHON also has an effect on the morphology of the photoreceptors.

Authors: Bhullar Paramjit K. , Grewal Dilraj S. , Fekrat Sharon
Published: September 2016

BACKGROUND AND OBJECTIVE:

To assess regional changes in choroidal thickness in the affected temporal hemifield of eyes with branch retinal artery occlusion (BRAO) compared to the unaffected temporal hemifield of the same eye and to fellow eyes.

PATIENTS AND METHODS:

Six eyes of six patients with unilateral BRAO with fellow eyes serving as controls. Using optical coherence tomography, choroidal thickness was measured at 49 points and averaged for each hemifield.

RESULTS:

In BRAO eyes, choroidal thickness was greater in the affected hemifield (209.5 µm ± 13.9 µm) compared to the unaffected hemifield (181.3 µm ± 8.9 µm;
P
= .001). In fellow-eyes, there was no difference between the two hemifields (180.3 µm ± 18.1 µm vs. 193.7 µm ± 16 µm;
P
= .39). The choroid was thicker in the affected BRAO eye hemifield compared to the corresponding fellow eye hemifield (209.5 µm ± 13.9 µm vs. 180.3 µm ± 18.1 µm;
P
= .01), whereas no difference was observed among unaffected BRAO eye hemifield and corresponding fellow eye hemifield (181.3 µm ± 8.9 µm vs. 193.7 µm ± 16 µm;
P
= .1). Subfoveal choroidal thickness between BRAO and fellow eyes was similar (185.5 µm ± 25.7 µm vs. 194.5 µm ± 20.8 µm;
P
= .4).

CONCLUSION:

The choroid was 15.6% thicker in the affected hemifield of BRAO eyes compared to the unaffected hemifield of same eye and 16.2% thicker than the corresponding hemifield in fellow eyes.

Retinotomy Closure Following Subretinal Stem Cell Transplant With a 30-Gauge Needle
Authors: Ludwig Cassie A. , Leng Theodore
Published: September 2016

The authors report two cases of posterior retinotomy closure following subretinal stem cell transplantation for age-related macular degeneration with a 30-gauge needle — a larger bore needle than those used in prior studies. Partial retinotomy closure was seen on optical coherence tomography within 24 hours in one patient, whereas complete closure occurred by the 5-month and 1-year follow-up visits. A trace retinal hemorrhage occurred in one case, with resolution by 12 weeks. These findings demonstrate the likelihood of uncomplicated, spontaneous retinotomy closure following subretinal stem cell transplantation with a 30-gauge needle.

Cuteness, friendship, and identity in the brony community
Authors: Peck-Suzuki Theo A.
Published: September 2016

I examine the practices of fan productivity and gender negotiation in brony fandom, the community of primarily college-age men who are fans of My Little Pony: Friendship Is Magic (2010–). I examine the contours of brony textual and material practices, noting how productivity within the fandom plays a role in the negotiation of identity and community ethos. I also consider the implications of cuteness in the fandom and discuss how this aesthetic and its corresponding narrative have led to the development of a unique discursive mode among bronies, which I term the discourse of friendship. Drawing on Matthew Gutmann's theory of contradictory consciousness, I argue that the discourse of friendship is an innovative framework that encourages new ways of taking part in existing social institutions that destabilize hegemonic masculinity.
Fannish masculinities in transition in anime music video fandom
Authors: Close Samantha
Published: September 2016

Politically engaged scholarship often interrogates the experiences of groups without privilege. But in order for social change to happen, privileged identities must also be reworked. An analysis of anime fandom in the early 2000s shows that fan works, such as fan video and cosplay performances, concretize masculinities that are both transgressive and desperately seeking normative confirmation. By means of queer and masculinity theory, I argue that fandom is a uniquely generative space for reworking masculinity. This will only remain true, however, if it can hold onto its subversive practices in a time of increasing mainstream attention.
Hoarding and community in "Star Wars Card Trader"
Authors: Groskopf Jeremy
Published: September 2016

Transitioning collectibles from the physical to the digital sphere changes the culture of collecting by increasing the accessibility of trading partners and adding digital limitations on personal interaction. In this analysis, I examine the collecting game Star Wars Card Trader (2015) and its culture of mass hoarding—the collecting of vast quantities of a single, valueless digital object—through which players reintroduce elements of personality, camaraderie, and nonrivalrous collecting into a system designed primarily for anonymous profitable acquisition. Via an analysis of player behaviors both within the game itself and in online venues, I argue that mass hoarding—a user invention—acts as the central community-building behavior in this digital realm. Mass hoarding is thus a clear indication that even in the digital realm, human personalities and relationships are vital to the construction of collecting as a pastime that is more complex than an investment opportunity.

GREEN BUILDING AND BIODIVERSITY: FACILITATING BIRD FRIENDLY DESIGN WITH BUILDING INFORMATION MODELS
Authors: Kensek Karen , Ding Ye , Longcore Travis
Published: September 2016

Green buildings should respect nature and endeavor to mitigate harmful effects to the environment and occupants. This is often interpreted as creating sustainable sites, consuming less energy and water, reusing materials, and providing excellent indoor environmental quality. Environmentally friendly buildings should also consider literally the impact that they have on birds, millions of them. A major factor in bird collisions with buildings is the choice of building materials. These choices are usually made by the architect who may not be aware of the issue or may be looking for guidance from certification programs such as LEED. As a proof of concept for an educational tool, we developed a software-assisted approach to characterize whether a proposed building design would earn a point for the LEED Pilot Credit 55: Avoiding Bird Collisions. Using the visual programming language Dynamo with the common building information modeling software Revit, we automated the assessment of designs. The approach depends on parameters that incorporate assessments of bird threat for façade materials, analyzes building geometry relative to materials, and processes user input on building operation to produce the assessment.
INNOVATIVE HOUSING ADOPTION: MODULAR HOUSING FOR THE AUSTRALIAN GROWING FAMILY
Authors: Phillips Daniell , Guaralda Mirko , Sawang Sukanlaya
Published: September 2016

Housing must be flexible to the circumstances growing families face as their needs change during the family lifecycle. The purpose of this paper is to gather a preliminary understanding of growing families' needs and evaluate how modular off-site manufactured construction could effectively answer those needs. Despite the large amount of research that has gone into off-site manufactured buildings, there is little research that has explored its suitability as a flexible housing typology for growing families. The pilot presented in this paper investigates the specific context of Brisbane, Australia; qualitative data have been gathered from growing families in this city and combined with established theory on flexible building to develop a preliminary understanding of how modular off-site manufactured construction could perform in meeting flexibility requirements in comparison to a traditional lightweight timber framed construction. Findings highlight how the ability to modify a dwelling is a fundamental feature for growing families; a number of other advantages in flexibility were found in modular off-site manufacture and recommendations made to improve this construction typology.
SUSTAINABLE DESIGN IN PROJECT DELIVERY: A DISCUSSION ON CURRENT AND FUTURE TRENDS
Authors: Widjaja Karno
Published: September 2016

INTRODUCTION

Sustainability principles have become an integral part of the design and construction process for many new construction projects. The selection of the project delivery method (PDM) is extremely important in the effective execution of the project, and plays a critical role in establishing communication and coordination between the key entities: owner, architect, and contractor.

The goal of this paper is to hopefully serve as a starting point for further discussion to improve on the AEC industry's current integration of sustainability principles in PDMs. The first step consists of an assessment of current project delivery systems from a sustainable design perspective. This is followed by a determination of the current limitations, and examination of the various disruptions in the industry. Various literature sources are analyzed to form a framework to discuss improvements and optimization strategies beyond the current system. Thereafter, proposed solutions are introduced at both stakeholders, as well as PDM scales.

In this paper, the focus for the conducted analysis and proposed methodologies is predicated on new construction projects instead of retrofits due to the resources available. However, the principles can similarly be applied to retrofit scenarios as well, depending on the specific requirements of the individual project at play.
WARMING ISSUES ASSOCIATED WITH THE LONG TERM SIMULATION OF HOUSING USING CFD ANALYSIS
Authors: Albatayneh Aiman , Alterman Dariusz , Page Adrian W. , Moghtaderi Behdad
Published: September 2016

The determination of internal building air temperature has an impact on the design and performance of a building in measuring thermal comfort and heating and cooling loads. There is software to assist with measuring internal building air temperature such as Autodesk CFD simulation. However, the use of Autodesk CFD simulation for the analysis appears to have an issue with simulations extending over a long term (i.e. months or years) as the internal air temperature in a building keeps rising with time. This paper addresses the challenges encountered using CFD simulation in the modelling of a building for long term performance. A new method to overcome the issue of the progressive rising of internal air temperature using two external air boundaries, one for the external volume (sky boundary) and the other surrounding the building, is suggested in the paper.

Published: September 2016

Fungal skin infections are caused by different types of fungi among these Malassezia species is the common cause of the dermatitis in human and animals. In the present study, the skin scraping samples were collected from human and dog. The samples were inoculated into Saboraud and potato dextrose broth to achieve the fungal growth. The fungal species were isolated and characterized by colony morphology, potassium hydroxide (KOH) and lacto phenol cotton blue staining. Genomic DNA was isolated and the 28S rRNA was amplified from fungal species using the universal primers and the amplified PCR products were subjected to sequencing. The sequence analysis of 28S rRNA reveals that two sequences were similar to Malassezia globosa and one sequence is similar to Malassezia pachydermatis which causes dermatitis in human and dog, respectively. Further study was carried out to assess the antifungal activity of the silver nanoparticles synthesized through green synthesis using Azadirachta indica leaf extract and characterized by UV-Visible spectrophotometer, Transmission electron microscope (TEM), X-Ray diffraction spectrophotometer (XRD) and Fourier transform infrared spectrophotometer (FTIR). The characterized silver nanoparticles inhibit the growth of Malassezia species by forming zone of clearance. This study suggests that the silver nanoparticles could be an alternative to treat the fungal infections.

Published: September 2016

First-principle ultrasoft pseudo potential approach of the plane wave based on density functional theory (DFT) has been used for studying the electronic characterization and optical properties of ZnO and Fe, Co doped ZnO. The results show that the doping impurities change the lattice parameters a little, but bring more changes in the electronic structures. The band gaps are broadened by doping, and the Fermi level accesses to the conduction band which will lead the system to show the character of metallic properties. The dielectric function and absorption peaks are identified and the changes compared to pure ZnO are analyzed in detail.
Enhancement in Curie Temperature with Magnesium Substituted in Sintered MgxMn1-xFe2O4 Pellets of Nanopowders
Authors: Manouchehri Sohrab , Mohammadi Benehi Seyed Taghi , Yousefi Mohammad Hassan
Published: September 2016

Ferrites nanopowder of spinel MgxMn1-xFe2O4 (with x=0.0, 0.2, 0.4, 0.6, 0.8 and 1.0) synthesized by the coprecipitation method and pellets of nanopowder sintered at temperature 1250 °C. The X-ray diffraction results confirmed the single phase formation of the samples. The lattice constant and interionic distances decreased with increase in magnesium content that can be originated by strengthening of A–B interaction. The substitution effect of nonmagnetic Mg2+ ions was studied on Curie temperature of sintered pellets. Curie temperature measurements exhibit increasing trend with increase in magnesium content. Enhancement in Curie temperature can be explained on the basis of strengthening of A–B interaction and Neel’s two sub-lattice models.

Published: September 2016

Bacterial cellulose (BC) is a biopolymer with interesting properties, such as biocompatibility, high tensile strength, high absorption capacity, water retention and high crystallinity. Nanoparticles of titanium dioxide (TiO2) are extremely important in electrical applications, photocatalysis, sensors and biomedical areas. Multifunctional materials, based on bacterial cellulose, with differentiated properties can be designed from the BC/TiO2 nanocomposite by ex situ method of sol-gel immersion. It was manufactured as a nanocomposite consisting of BC/TiO2 hydrogel. Characterizations were carried out by scanning electron microscope (SEM), energy dispersive spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR). The morphological analysis of nanocomposite revealed the existence of molecular interaction and adhesion between TiO2 nanoparticles and cellulosic nanofibers matrix, where the presence of Ti peaks in EDS spectra was discovered, proving the successful incorporation of nanoparticles. The FTIR showed modification on the functional groups, suggesting interaction between the components. The manufacturing of a BC/TiO2 nanocomposite by method of sol-gel immersion has a great potential for future applications.
Nanoscale Modulation of Material Properties by Means of Irradiation
Authors: Selyshchev Pavlo , Sugakov V.
Published: September 2016

A theoretical approach is developed to describe creation of space-periodical modulation of microstructure by means irradiation and influence of this modulation on properties of the irradiated material. It has considered nonlinear dynamics of development of radiation-induced defects. The structure of defects drives microstructure and changes material properties. It is found that nanoscale space-periodical distribution is results of interaction of radiation-induced defects both with each other and with elements of microstructure. It is shown that homogenous defect distribution become instable and bifurcation happen with respect to development of space-periodical distribution. Thus change of microstructure and material properties become space-periodical. Period of inhomogeneity and bifurcation values of parameters have been obtained.

Metal hydride alloys are considered as promising materials because they are viewed as an attractive alternative to conventional hydrogen storage cylinders and mechanical hydrogen compressors. Compared to storing in a classic gas cylinder, which requires compression of hydrogen at high pressures, metal hydride alloys can store the same amount of hydrogen at nearly room pressure. However, this hydrogen absorption necessitates an effective way to reject the heat released from the exothermic hydriding reaction. In this paper, fin structures are employed to enhance the heat transfer of metal hydride alloys in a cylindrical reactor. Numerical simulations are performed based on a multiple-physics modeling to analyze the transient heat transfer during the hydrogen absorption process. The objective is to minimize the time elapsed for the process and to reduce the hotspot temperature by determining the number and shape of rectangular fins while the total volume of fins used are fixed. The simulation results show that the more fins are applied the better heat transfer is achieved and that there exists an optimal length of the fins.

Published: September 2016

The dielectric properties of ZnO and Al2O3 are dependent upon various factors such as chemical composition, method of synthesis, grain size, particle size distribution and porosity. A low dielectric constant is often desirable for several applications, whilst for enhanced oil recovery application, high loss dielectrics is required rendering the particles as surface-active agent. In this study, the dependence of the dielectric properties on the calcination temperature of ZnO and Al2O3 nanoparticles is determined as a function of two applied radio frequencies of 18.82 MHz and 167.32 MHz. The experimental results indicate that the nanoparticles of different phases can significantly improve the densification and their dielectric properties. Detailed analysis of the results showed that rotational polarization is the major contributor to the enhanced dielectric behavior of the nanoparticles at the applied frequencies.

Authors: Marwan
Published: September 2016

An important phase of the MgO-SiO2-Al2O3 system, α-cordierite was studied for its catalytic transesterification activity in preparing palm biodiesel. The prime drawback of such solid catalyst is its low activity. To overcome this problem, the transesterification was combined with microwave irradiation. The effect of reaction time and catalyst loading on biodiesel yield was investigated in a batch reaction mode. The synthesis of biodiesel was confirmed by 1H NMR spectroscopy. It reveals that an enhanced yield of biodiesel was obtained, whereas the maximum yield was reached in less than 30 min regardless the catalyst loading. As a solid type catalyst, this result becomes a platform to develop the flow mode reaction unit using a cordierite based structured catalyst without modifying surface chemistry of cordierite.

Basic oxygen furnace (BOF) slag is characterized by high hardness, low abrasion, and high roughness. It is suitable as graded aggregate for engineering applications. However, the conversion process generated a great amount of unreacted free CaO, resulting in expansion and thus making the slag inconvenient for use in engineering applications. Accelerated carbonation of BOF slag is equivalent to natural weathering. Moreover, it can effectively shorten the weathering time. This study found that accelerated carbonation not only reduce expansion behaviors but also strengthen physical and mechanical properties. According to test results, the abrasion resistant, soundness, California bearing ratio, shear strength, and compressive strength have increased after carbonation.
Predicting the Duration of Manufacturing Process with Two Complement Materials

Published: September 2016

In the marketing, there are some correlated between two complement materials when predicting the duration of manufacturing process. Two different kinds of materials are complementary if using more of one material requires the use of more of another. Thus, based on this view of point, when we estimate the production demand quantity, we can’t consider these two durations of manufacturing process as dependent. In this paper we propose the bivariate exponential distribution to model two related manufacturing durations of two complement materials. Finally, we demonstrate both MLE and moment methods to estimate the parameters of our model. This can provide the reference for the future study to choice a suitable estimation.

In this paper we analyze the forming mechanism of composite abrasive grains in oxide film on ELID grinding wheel surface, By using composition information and by taking advantage of microscale structure, we have investigated that abrasive grains surface is covered by a layer of oxide film and the fresh oxide film is loose and porous like turtle shaped crack when crushed and dried. The elements of oxide film consist of α-Fe2O3 with sphere grain of 5-50nm. This phenomena is demonstrated that the composite abrasive grains in oxide film is a compound structure which is centered by abrasive grains, with α-Fe2O3,Fe (OH)3 surrounded.

In cookware manufacturing industry, spray coating process plays an important role both in function and appearance quality of a product. Typically, Teflon (PTFE) is used for interior coating to increase corrosive and nonstick. Practically, nozzle size and spray time are crucial variables to dry file thickness (DFT) in the process. In mass production, a product is mounted on a rotating spindle which installed on the conveyor and moves pass the spray guns. Thus, the rotating speed is also a potential variable to the DFT. Thus, the objective of this paper is to explore a relationship of these abovementioned three variables i.e. nozzle size, spray time, and rotational speed to dry film thickness After that the optimal condition such that the required DFT is met will be determined. To achieve this goal, the experimental design technique including analysis of variance (ANOVA) is employed in this study. It is found that each of the three variables affects the DFT. The higher of spray time, nozzle size, and rotational speed, the more coating thickness onto the part.
Long-Lived CD4+IFN-γ+ T Cells rather than Short-Lived CD4+IFN-γ+IL-10+ T Cells Initiate Rapid IL-10 Production To Suppress Anamnestic T Cell Responses during Secondary Malaria Infection

CD4+ T cells that produce IFN-γ are the source of host-protective IL-10 during primary infection with a number of different pathogens, including Plasmodium spp. The fate of these CD4+IFN-γ+IL-10+ T cells following clearance of primary infection and their subsequent influence on the course of repeated infections is, however, presently unknown. In this study, utilizing IFN-γ–yellow fluorescent protein (YFP) and IL-10–GFP dual reporter mice, we show that primary malaria infection–induced CD4+YFP+GFP+ T cells have limited memory potential, do not stably express IL-10, and are disproportionately lost from the Ag-experienced CD4+ T cell memory population during the maintenance phase postinfection. CD4+YFP+GFP+ T cells generally exhibited a short-lived effector rather than effector memory T cell phenotype postinfection and expressed high levels of PD-1, Lag-3, and TIGIT, indicative of cellular exhaustion. Consistently, the surviving CD4+YFP+GFP+ T cell–derived cells were unresponsive and failed to proliferate during the early phase of secondary infection. In contrast, CD4+YFP+GFP− T cell–derived cells expanded rapidly and upregulated IL-10 expression during secondary infection. Correspondingly, CD4+ T cells were the major producers within an accelerated and amplified IL-10 response during the early stage of secondary malaria infection. Notably, IL-10 exerted quantitatively stronger regulatory effects on innate and CD4+ T cell responses during primary and secondary infections, respectively. The results in this study significantly improve our understanding of the durability of IL-10–producing CD4+ T cells postinfection and provide information on how IL-10 may contribute to optimized parasite control and prevention of immune-mediated pathology during repeated malaria infections.

The spinal cord is involved in local, ascending and descending neural pathways. Few studies analyzed the distribution of neuromediators in the laminae of non-human primates along all segments. The present study described the classic neuromediators in the spinal cord of the non-human primate Sapajus spp. through histochemical and immunohistochemical methods. Nicotinamide adenine dinucleotide hydrogen phosphate-diaphorase (NADPH-d) method showed neuronal somata in the intermediolateral column (IML), central cervical nucleus (CCN), laminae I, II, III, IV, V, VI, VII, VIII and X, besides dense presence of nerve fibers in laminae II and IX. Acetylcholinesterase (AChE) activity was evident in the neuronal somata in laminae V, VI, VII, VIII, IX, CCN, IML and in the Clarke’s column (CC). Immunohistochemistry data revealed neuronal nitric oxide synthase (nNOS) immunoreactivity  in neuronal somata and in fibers of laminae I, II, III, VII, VIII, X and IML; choline acetyltransferase (ChAT) in neuronal somata and in fibers of laminae VII, VIII and IX; calcitonin gene-related peptide (CGRP) was noticed in neuronal somata of lamina IX and in nerve fibers of laminae I, II, III, IV, V, VI and VII; substance P (SP) in nerve fibers of laminae I, II, III, IV, V, VI, VII, VIII, IX, X, CCN, CC and IML; serotonin (5-HT) and vesicular glutamate transporter-1 (VGLUT1) was noticed in nerve fibers of all laminae;  somatostatin (SOM) in neuronal somata of laminae III, IV, V, VI, VII, VIII and IX and nerve fibers in laminae I, II, V, VI, VII, X and IML; calbindin (Cb) in neuronal somata of laminae I, II, VI, VII, IX and X; parvalbumin (PV) was found in neuronal somata and in nerve fibers of laminae III, IV, V, VI, VII, VIII, IX and CC; finally, gamma-amino butyric acid (GABA) was present in neuronal somata of laminae V, VI, VII, VIII, IX and X. This study revealed interesting results concerning the chemoarchitecture of the Sapajus spp. spinal cord with a distribution pattern mostly similar to other mammals. The data corroborate the result described in literature, except for some differences in CGRP, SP, Cb, PV and GABA immunoreactivities present in neuronal somata and in nerve fibers. This could suggest certain specificity for the neurochemistry distribution in this non-human primate species, besides adding relevant data to support further studies related to processes involving spinal cord components.
