Modeling of weak anisotropic anchoring of nematic liquid crystals in the Landau-de Gennes theory

The anisotropic anchoring effect of a treated solid surface on a nematic liquid crystal is described in the Landau-de Gennes theory using a power expansion on the tensor-order parameter and two mutually orthogonal unit vectors. The expression has three degrees of freedom, allowing for independent assignment of polar and azimuthal anchoring strengths and a preferred value of the surface-order parameter. It is shown that in the limit for a uniaxial constant-order parameter, the expression simplifies to the anisotropic generalization of the Rapini-Papoular anchoring energy density proposed by Zhao et al. Experimentally measurable values with a physical meaning in the Oseen-Frank theory can be scaled and assigned to the scalar coefficients of the tensor-order-parameter expansion. Results of numerical experiments comparing the anchoring according to the study of Zhao et al. in the Oseen-Frank theory and the power expansion in the Landau-de Gennes theory are presented and shown to agree well

Nature of water-biochar interface interactions

A poplar biochar obtained by an industrial gasification process was saturated with water and analyzed using fast field cycling (FFC) NMR relaxometry in a temperature range between 299 and 353 K. Results revealed that the longitudinal relaxation rate increased with the increment of the temperature. This behavior was consistent with that already observed for paramagnetic inorganic porous media for which two different relaxation mechanisms can be accounted for: outer- and inner-sphere mechanisms. The former is due to water diffusing from the closest approach distance to infinity, whereas the second is due to water interacting by nonconventional H-bonds to the porous surface of the solid material. In particular, the inner-sphere relaxation appeared to be predominant in the water-saturated biochar used in the present study. This study represents a fundamental first step for the full comprehension of the role played by biochar in the draining properties of biochar-amended soils

Evaluating Compassion-Mindfulness Therapy for Recurrent Anxiety and Depression: A Randomized Control Trial

Objective: To evaluate the effects of compassion–mindfulness therapy (C-MT), an adapted version of mindfulness-based cognitive therapy that integrates compassion training.Method: Individuals aged 17–69 with recurrent depressive and anxiety symptoms were recruited from a community mental health service unit. Half of the participants were randomized to an 8-week C-MT program (n = 41) and the other half to a wait-list control condition (n = 41).Results: Intent-to-treat analyses showed significant improvements in all measures in the treatment group. The effect sizes for depression and anxiety were 1.11 and 1.10, respectively, and those for physical distress, daily functioning, positive affect, and negative affect ranged from 0.71 to 1.04. All improvements were sustained at the 3-month follow-up.Conclusions: The results provide preliminary support for C-MT as a viable treatment option for individuals with recurrent depression and anxiety symptoms. Time-limited treatments such as C-MT should be promoted in social work practice.postprin

Lattice distortions in a sawtooth chain with Heisenberg and Ising bonds

An exactly solvable model of the sawtooth chain with Ising and Heisenberg bonds and with coupling to lattice distortion for Heisenberg bonds is considered in the magnetic field. Using the direct transfer-matrix formalism an exact description of the thermodynamic functions is obtained. The ground state phase diagrams for all regions of parameters values containing phases corresponding to the magnetization plateaus at $M=0,1/4$ and 1/2 have been obtained. Exact formulas for bond distortions for various ground states are presented. A novel mechanism of magnetization plateau stabilization corresponding to $M=1/4$ state is reported.Comment: 16 pages, 12 figure

Process optimization of ultrasonication-assisted extraction to obtain antioxidant-rich extract from Spirulina platensis

In this study highlights on the optimization of extraction process parameters of total phenolic content and antioxidant activity from Spirulina platensis, through ultrasonication (probe) technology. Especially, optimization of ultrasonication parameters was carried out employing Box-Behnken Design (BBD) and response surface methodology. Alongside the three levels of extraction parameters i.e. solvent volume, extraction time and frequency have been fixed. As responses, the total yield of extract, total phenolic content and DPPH radical scavenging activity (IC50) of the extracts were determined. The variability of each response variable was determined by developing multiple linear regressions. The statistical analysis (ANOVA) of developed mathematical models allowed the prediction of the behaviour of the responses, as a function of the variables involved in the process. The optimized extraction conditions were obtained at 58.76 kHz frequency, 10 mL of solvent volume for 6 min. Simultaneously this extract exhibited the highest content of total phenolic content (30.89 mg GAE/g powder), IC50 for DPPH activity (151.27 µg/mL). The extract exhibited an important antioxidant i.e. caffeic acid, which was quantified as 660.72±41.05 µg/g of dry algal powder using HPLC. In spite of fact that, this study offers an alternative method for obtaining natural antioxidants from algae for food and pharmaceutical applications. Keywords: Microalgae; Probe sonication extraction; Total phenolic content; Antioxidant activit

Preliminary attempt to develop a path-flow analysis model for swimming performance in children

The goal of competitive swimming is to travel the event distance as fast as possible. The identification of the parameters that predict swimming performances is one of the main aims of the swimming “science” community. Indeed, it is consensual that biomechanical and energetic variables are determinant for performance in this sport. Several research groups dedicate their attention to the relationships establish between biomechanical and energetic variables on adult swimmers, with special emphasis on elite adult swimmers

Preliminary attempt to develop a path-flow analysis model for swimming performance in children

The aim of this research was to develop a path-flow analysis model from age-group swimmer’s performance based on biomechanical and energetic parameters. Twenty two young male age-group swimmers with several competitive levels volunteered to serve as subjects. It was assessed swim velocity, stroke length, stroke frequency, stroke index, propulsive efficiency, critical velocity and 200 m freestyle event performance. To verify the quality of the model, root mean square residuals (RMSR) was computed. The confirmatory model explained 54% of swimming performance. RMSR was 0.064. As a conclusion, the model based in biomechanical and energetic variables, according to the relationships suggested is appropriated to explain performance in age-group swimmers

How informative are the vertical buoyancy and the prone gliding tests to assess young swimmers hydrostatic and hydrodynamic profiles?

The aim of this research was to develop a path-flow analysis model to highlight the relationships between buoyancy and prone gliding tests and some selected anthropometrical and biomechanical variables. Thirty-eight young male swimmers (12.97 ± 1.05 years old) with several competitive levels were evaluated. It were assessed the body mass, height, fat mass, body surface area, vertical buoyancy, prone gliding after wall push-off, stroke length, stroke frequency and velocity after a maximal 25 [m] swim. The confirmatory model included the body mass, height, fat mass, prone gliding test, stroke length, stroke frequency and velocity. All theoretical paths were verified except for the vertical buoyancy test that did not present any relationship with anthropometrical and biomechanical variables nor with the prone gliding test. The good-of-fit from the confirmatory path-flow model, assessed with the standardized root mean square residuals (SRMR), is considered as being close to the cut-off value, but even so not suitable of the theory (SRMR = 0.11). As a conclusion, vertical buoyancy and prone gliding tests are not the best techniques to assess the swimmer’s hydrostatic and hydrodynamic profile, respectively
