Soils constitute the largest sink of terrestrial carbon (C), and urban soils have the potential to provide significant soil C storage. Soils in urbanized landscapes experience a multitude of human alterations, such as compaction and management subsidies, that impact soil C dynamics. While field studies may provide data on urban soil C storage, modeling soil C dynamics under various human impact scenarios will provide a basis for identifying drivers of urban soil C dynamics and for predicting the potential for these highly altered soils to store C over time intervals not typically amenable to empirical validation...

Recent appreciation of the multifactorial pathophysiology of skin aging has led to increased use of parallel treatment regimens. This prospective, split-face, randomized study assessed the safety and efficacy of same-day sequential Q-switched Nd:YAG laser and 1565 nm non-ablative fractional laser (SST) facial rejuvenation treatment in comparison to fractional non-ablative laser (NAFL) treatment only. Seventeen patients underwent three treatment sessions, conducted at 4-6-week intervals, in which SST treatment was delivered on a randomly selected side of the face followed by NAFL treatment on the contralateral side immediately thereafter...

Mesoporous carbon nitrides (MCN) with rod shaped morphology and tunable nitrogen contents have been synthesized via calcination free method using ethanol-washed mesoporous SBA-15 as templates at different carbonization temperatures. Carbon tetrachloride (CTC) and ethylenediamine (EDA) were used as the sources of carbon and nitrogen respectively. The resulting MCN materials were characterized with low and high angle power XRD, N2 adsorption, HR-SEM, HR-TEM, CHN elemental analysis, XPS and. XANES techniques. It is observed that the carbonization temperature plays a critical role in controlling not only the crystallinity but also the nitrogen content and the textural parameters of the samples including specific surface area and specific pore volume...

Jiachao Zhang, Keigo Hirakawa
This paper describes a study aimed at comparing the real image sensor noise distribution to the models of noise often assumed in image denoising designs. Quantile analysis in pixel, wavelet transform, and variance stabilization domains reveal that the tails of Poisson, signal-dependent Gaussian, and Poisson-Gaussian models are too short to capture real sensor noise behavior. A new Poisson mixture noise model is proposed to correct the mismatch of tail behavior. Based on the fact that noise model mismatch results in image denoising that undersmoothes real sensor data, we propose a mixture of Poisson denoising method to remove the denoising artifacts without affecting image details such as edge and textures...

Zeolitic imidazolate framework ZIF-8 beads of 2-3mm in diameter were prepared using a simple one-step phase inversion method. The beads were fabricated by different amounts of ZIF-8 to polyether sulfone (PES) ratios. ZIF-8 played the role of an adsorbent while PES acted as a binder in the composite matrix to keep the ZIF-8 particles. Since ZIF-8 is highly hydrophobic, the beads floated on water and adsorbed oil droplets successfully. This efficient oil adsorption is attributed to the hydrophobicity and high surface area of ZIF-8 particles which can effectively adsorb oil droplets...

Milk consumption in the United States has been in decline since the 1960s. Milk fat plays a critical role in sensory properties of fluid milk. The first objective of this study was to determine the change in percent milk fat needed to produce a detectable or just noticeable difference (JND) to consumers in skim, 1%, 2%, and whole milks. The second objective was to evaluate how milk fat affected consumer preferences for fluid milk. Threshold tests were conducted to determine the JND for each reference milk (skim, 1%, 2%, and whole milk), with a minimum of 60 consumers for each JND...

BACKGROUND: A change of loading conditions in the knee causes changes in the subchondral bone and may be a cause of osteoarthritis (OA). However, quantification of trabecular architecture in vivo is difficult due to the limiting spatial resolution of the imaging equipment; one approach is the use of texture parameters. In previous studies, we have used digital models to simulate changes of subchondral bone architecture under OA progression. One major result was that, using computed tomography (CT) images, subchondral bone mineral density (BMD) in combination with anisotropy and global homogeneity could characterize this progression...

BACKGROUND: Over the past few decades, beef producers in Japan have improved marbling in their beef products. It was recently reported that marbling is not well correlated with palatability as rated by Japanese consumers. Here we sought to identify the consumer segments in Japanese that prefer sensory characteristics of beef other than high marbling. RESULTS: Three Wagyu beef, one Holstein beef, and two lean imported beef longissimus samples were subjected to a descriptive sensory test, physicochemical analysis, and consumer (n = 307) preference test...

BACKGROUND: Potentially, pâtés could be a functional food and are an important source of proteins, vitamin A, B complex vitamins and iron. Unfortunately, one problem in pâtés is the high level of animal fat, about 30%. Pâté with low-fat guinea fowl meat and animal fat replaced with inulin can result in this product being classified as a pro-health food. The objective of the present study was to determine the effect on pâté with guinea fowl meat of reducing its pork back fat content (about 1/3, 2/3 and 100%) and the adding inulin as a partial fat substitute...

BACKGROUND: The aim of this study was to perform the partial replacement of bakery fat with barley β-glucan in muffins and to determine its effect on the physical properties of products. Most shortenings used in the industry are solid fats rich in saturated fatty acids and often trans fatty isomers, which are nutritionally unfavorable. METHODS: Dough and baked muffins were used as the research material. Five muffin recipes were prepared: control (K0%) with 16% fat content in the total dough weight, with fat content decreased by 10% (PG10%), 15% (PG15%), 20% (PG20%) and 25% (PG25%)...

Magnesium/hydroxyapatite composites were produced by conventional extrusion and their mechanical behavior studied under uniaxial compression at room temperature. The results evidence the capability of the HA for strengthening the Mg material, lowering its microstructural anisotropy and inhibiting deformation twinning. They also reveal that the ECAP processing is effective for improving the grain structure and reducing the crystallographic texture of these composites, giving rise to a significant enhancement of their yield strength and microhardness although the ultimate compressive stress worsens...

The dry reforming of methane (DRM), i.e. the reaction of methane and CO2 to form a synthesis gas, converts two major greenhouse gases into a useful chemical feedstock. In this work, we probe in detail the effect and role of Fe in bimetallic NiFe dry reforming catalysts. To this end, monometallic Ni, Fe and bimetallic Ni-Fe catalysts supported on a MgxAlyOz-matrix derived via a hydrotalcite-like precursor were synthetized. Importantly, the textural features of the catalysts, i.e. the specific surface area (172-178 m2/gcat), pore volume (0...

PURPOSE: Early identification of ischemic stroke plays a significant role in treatment and potential recovery of damaged brain tissue. In noncontrast CT (ncCT), the differences between ischemic changes and healthy tissue are usually very subtle during the hyperacute phase (< 8 h from the stroke onset). Therefore, visual comparison of both hemispheres is an important step in clinical assessment. A quantitative symmetry-based analysis of texture features of ischemic lesions in noncontrast CT images may provide an important information for differentiation of ischemic and healthy brain tissue in this phase...

Particulated complexes composed of oppositely charged biopolymers were incorporated into highly concentrated protein matrices as potential fat replacers and structuring agents. A multistep procedure was therefore utilized to generate process-stable complexes, which were subsequently embedded into emulsion-type sausages, whereas macro- and microstructural properties were then assessed. Firstly, stock WPI and sugar beet pectin solutions were mixed under neutral conditions (pH 7) at various biopolymer ratios r (2 : 1, 5 : 1, 8 : 1)...
