Red ceramic industry in southern Brazil commonly uses wood biomass as furnace fuel generating great amounts of gas emissions and ash. To avoid their impact on atmospheric environment, wet scrubbing is currently being applied in several plants. However, the water leachate formed could be potentially toxic and not managed as a common water-based effluent, since the resulting wastewater could carry many toxic compounds derived from wood pyrolysis. There is a lack of studies regarding this kind of effluent obtained specifically and strictly from wooden-based biomass furnaces...

The surface properties play a particularly important role in the mucoadhesive drug delivery systems. In these formulations, the adsorption of polymer matrix to mucous membrane is limited by the wetting and swelling process of the polymer structure. Hence, the performance of mucoadhesive drug delivery systems made of polymeric materials depends on multiple factors, such as contact angle, surface free energy and water absorption rate. The aim of our study was to analyze the effect of model saliva and vaginal fluids on the wetting properties of selected mucoadhesive (Carbopol 974P NF, Noveon AA-1, HEC) and film-forming (Kollidon VA 64) polymers as well as their blends at the weight ratio 1:1 and 1:1:1, prepared in the form of discs...

Evaluation of vertical distribution of radiocesium in bottom sediment by measuring vertical γ-ray count profile was discussed. A stable inversion formula was derived based on the maximum entropy method. Efficiency of the formula was confirmed by using a low-cost apparatus composed of an array of PIN photodiodes and a single board computer with real-time inversion code. In-door experiment by using five model sediment disks showed good reproducibility of vertical radiocesium profile. On-site experiment was also carried out at a pond in Fukushima to confirm the efficiency...

This study involved a field-based investigation to assess the occurrence, distribution and bioaccumulation behaviour of hydrophobic organic contaminants in a large-scale constructed wetland. Samples of raw leachate, water and wetland plants, Typha angustifolia, were collected for chemical analysis. Target contaminants included polychlorinated biphenyls (PCBs), organochlorine pesticides (OCP), as well as several halogenated flame retardants (HFRs) and personal care products (triclosan and synthetic musks). In addition to PCBs and OCPs, synthetic musks, triclosan (TCS) and dechlorane plus stereoisomers (syn- and anti-DPs) were frequently detected...

Experimental prediction of drug-target interactions is expensive, time-consuming and tedious. Fortunately, computational methods help narrow down the search space for interaction candidates to be further examined via wet-lab techniques. Nowadays, the number of attributes/features for drugs and targets, as well as the amount of their interactions, are increasing, making these computational methods inefficient or occasionally prohibitive. This motivates us to derive a reduced feature set for prediction. In addition, since ensemble learning techniques are widely used to improve the classification performance, it is also worthwhile to design an ensemble learning framework to enhance the performance for drug-target interaction prediction...

Assessment of exposure to cosmetic products via the skin is important for evaluating the risks associated with the use of these products. However, few exposure studies have been conducted with babies, particularly in Asia. The aim of our study was to assess the exposure to selected cosmetic products in babies under the age of 36 months, over both winter and summer months. We evaluated exposure for seven cosmetic baby care products identified in a previous web-based survey as being commonly used by Korean parents...

The recent VIEW studies have demonstrated the non-inferiority of monthly and bi-monthly aflibercept in the management of wet age related macular degeneration (AMD) compared with ranibizumab. However, the current data are limited mainly to fixed dosing regimens with few studies looking at flexible dosing regimens of aflibercept in wet AMD. In addition, recent data from the VIEW 96 week extension has shown that patients being shifted from fixed dosing regimens to PRN have shown a drop in visual acuity and increase in central macular thickness...

Frequent involvement of the disc in temporomandibular joint (TMJ) disorders warrants attempts to tissue engineer TMJ disc replacements. Physiologically, a great degree of similarity is seen between humans and farm pigs (FPs), but the pig's rapid growth confers a significant challenge for in vivo experiments. Minipigs have a slower growth rate and are smaller than FPs, but minipig TMJ discs have yet to be fully characterized. The objective of this study was to determine the suitability of the minipig for TMJ studies by extensive structural and functional characterization...

Evaporation-induced assembly of nanoparticles in a drying droplet is of great importance in many engineering applications, including printing, coating and thin film processing. The investigation of particle dynamics in evaporating droplets can provide fundamental hydrodynamic insight for revealing the processing-structure relationship in the particle self-organization induced by solvent evaporation. We develop a free-energy-based multiphase lattice Boltzmann method coupled with Brownian dynamics to simulate evaporating colloidal droplets on solid substrates with specified wetting properties...

Large-volume-expansion-induced material pulverization severely limits the electrochemical performance of red phosphorous (P) for energy-storage applications. Hollow nanospheres with porous shells are recognized as an ideal structure to resolve these issues. However, a chemical synthetic approach for preparing nanostructured red P is always of great challenge and hollow nanosphere structures of red P have not yet been fabricated. Herein, a wet solvothermal method to successfully fabricate hollow P nanospheres (HPNs) with porous shells via a gas-bubble-directed formation mechanism is developed...

A biomimetic cellular-eating phenomenon in gallium-based liquid metal to realize particle internalization in full-pH-range solutions is reported. The effect, which is called liquid metal phagocytosis, represents a wet-processing strategy to prepare various metallic liquid metal-particle mixtures through introducing excitations such as an electrical polarization, a dissolving medium, or a sacrificial metal. A nonwetting-to-wetting transition resulting from surface transition and the reactive nature of the intermetallic wetting between the two metallic phases are found to be primarily responsible for such particle-eating behavior...

Cervical cancer usually presents in advanced stages and is treated with chemoradiation. About 15-20 % patients present with local recurrence after chemoradiation. Radical surgical resection is the only treatment modality offering long term survival benefit in recurrent cervical cancer. The most common surgical option for these patients is pelvic exenteration. Radical hysterectomy may be done for patients with a small centrally located recurrence in the cervix with no infiltration of adjacent structures. The aim of this study was to evaluate the morbidity and survival outcome following radical hysterectomy and pelvic exenteration for recurrent cancer cervix...

Changes in vegetation cover associated to the observed greening may affect several biophysical processes, whose net effects on climate are unclear. Here, we analyze remotely sensed dynamics in leaf area index (LAI) and energy fluxes to explore the associated variation in local climate. We show that the increasing trend in LAI contributed to the warming of boreal zones through a reduction of surface albedo, and to an evaporation-driven cooling in arid regions. The interplay between LAI and surface biophysics is amplified up to five times under extreme warm-dry and cold-wet years...

  This study investigated the impact of climate change on the Tuul River flow in a semiarid region in Mongolia using statistical methods and the Soil and Water Assessment Tool (SWAT). The authors found that the precipitation showed cyclic variability (three dry and two wet periods) at inter- and multi-decadal scales throughout the study period (1945-2012). Both river flow and actual evapotranspiration (ET) showed a positive relationship with precipitation. In addition, the river flow further decreased due to increased water loss in percentage via actual ET even though the amount of actual ET decreased during dry periods...
