Influence of Grow‐Out Feed Fatty Acid Composition on Finishing Success in Nile Tilapia

Abstract The fatty acid (FA) composition of cultured finfish can be tailored by transitioning fish reared on alternative lipid-based, low long-chain polyunsaturated FA (LC-PUFA) content grow-out feeds to high LC-PUFA finishing feeds based on fish oil (FO) before harvest. To determine whether the FA composition of the grow-out feed influences finishing success in Nile tilapia Oreochromis niloticus, coconut (CO), grapeseed (GO), linseed (LO), and poultry (PO) oils were evaluated in grow-out feeds with respect to production performance and responsiveness to finishing. The production performance of Nile tilapia was unaffected by application of the various feeding regimes, indicating that this species can effectively utilize CO, GO, LO, PO, and FO in aquafeeds. Implementation of the alternative lipid sources was associated with altered fillet FA composition. Although the differences were not significant in all cases, the levels of FO-associated FAs (e.g., 20:5[n-3] and 22:6[n-3]) were elevated among finished g.
Research on Influencing Factors of Welfare Level about Left-behind Children in China Rural Areas

Based on the survey data of 360 left-behind children at junior school in Xinyang city Henan province in China, the welfare of left-behind children was analyzed by using Amartya.Sen ability method theory and fuzzy mathematics. The results showed that left-behind children's material welfare of the economy increased, but their social mental welfare level declined when their parents went to work at other cities. As a result, the level of total welfare utility is low. At last, in order to increase the general welfare of left-behind children, policies and suggestions were provided according to the analysis.
Oxidation-reduction mechanism of iron in dioctahedral smectites: II. Crystal chemistry of reduced Garfield nontronite

Abstract The crystallochemical structure of reduced Garfield nontronite was studied by X-ray absorption pre-edge and infrared (IR) spectroscopy, powder X-ray diffraction, polarized extended X-ray absorption fine structure (P-EXAFS) spectroscopy, and texture goniometry. Untreated and highly reduced (>99% of total Fe as Fe2+) nontronite samples were analyzed to determine the coordination number and the crystallographic site occupation of Fe2+, changes in in-plane and out-of-plane layer structure and mid-range order between Fe centers, and to monitor the changes in structural and adsorbed OH/H2O groups in the structure of reduced nontronite. Contrary to earlier models predicting the formation of fivefold coordinated Fe in the structure of nontronites upon reduction, these new results revealed that Fe maintains sixfold coordination after complete reduction. In-plane PEXAFS evidence indicates that some of the Fe atoms occupy trans-sites in the reduced state, forming small trioctahedral domains within the structure of reduced nontronite. Migration of Fe from cisto trans sites during the reduction process was corroborated by simulations of X-ray diffraction patterns which revealed that about 28% of Fe2+ cations exist in trans sites of the reduced nontronite, rather than fully cis occupied, as in oxidized nontronite. Out-of-plane P-EXAFS results indicated that the reduction of Fe suppressed basal oxygen corrugation typical of dioctahedral smectites, and resulted in a flat basal surface which is characteristic of trioctahedral layer silicates. IR spectra of reduced nontronite revealed that the dioctahedral nature of the nontronite was lost and a band near 3623 cm-1 formed, which is thought to be associated with trioctahedral [Fe2+]3OH stretching vibrations. On the basis of these results, a structural model for the reduction mechanism of Fe3+ to Fe2+ in Garfield nontronite is proposed that satisfies all structural data currently available. The migration of reduced Fe ions from cis-octahedra to adjacent trans-octahedra is accompanied by a dehydroxylation reaction due to the protonation of OH groups initially coordinated to Fe. This structural modification results in the formation of trioctahedral Fe2+ clusters separated by clusters of vacancies in which the oxygen ligands residing at the boundary between trioctahedral and vacancy domains are greatly coordination undersaturated. The charge of these O atoms is compensated by the incorporation of protons, and by the displacement of Fe2+ atoms from their ideal octahedral position toward the edges of trioctahedral clusters, thus accounting for the incoherency of the Fe-Fe1 and Fe-Fe2 distances. From these results, the ideal structural formula of reduced Garfield nontronite is Na1.30[Si7.22Al0. 78] [Fe2+3.65Al0. 32Mg0.04]O17.93(OH)5 in which the increased layer charge due to reduction of Fe3+ to Fe2+ is satisfied by the incorporation of protons and interlayer Na.
GENERALIZING CONVOLUTIONAL NEURAL NETWORKS FOR PATTERN RECOGNITION TASKS

Convolutional Neural Network (CNN) promises automatic learning and less effort for hand-design heuristics in building an efficient pattern recognition system. It requires simple and minimal preprocessing stages for data preparation. These features enable CNN architecture to be applied to various pattern recognition applications. This paper proposes a fourlayered CNN architecture that caters to face recognition and finger-vein biometric identification case studies. The methodology applied in designing the network is discussed in detail. For face recognition, the design is evaluated on three facial image databases with different levels of complexities. These databases are AT&T, AR Purdue, and FERET. The same four-layered CNN architecture is also tuned for finger-vein biometric identification problems. The design performance is evaluated on finger-vein biometric database developed in-house, consisting of 81 subjects. The results obtained from these case studies are promising. For face recognition applications, 100%, 99.5%, and 85.16% accuracies were obtained for AT&T, AR Purdue, and FERET, respectively. On the other hand, the result obtained from the finger-vein biometric identification case study has 99.38% accuracy. The results have shown that the proposed design is feasible for any pattern recognition problem
Quenched exit times for random walk on dynamical percolation

We consider random walk on dynamical percolation on the discrete torus $\mathbb{Z}_n^d$. In previous work, mixing times of this process for $p<p_c(\mathbb{Z}^d)$ were obtained in the annealed setting where one averages over the dynamical percolation environment. Here we study exit times in the quenched setting, where we condition on a typical dynamical percolation environment. We obtain an upper bound for all $p$ which for $p<p_c$ matches the known lower bound.
ПЕЛЬМЕНИ or 饺子 ? Dietary Acculturation among Russian Immigrants in Beijing

Emerging multiculturalism in China's metropolitan areas implies people's frequent engagement in intercultural contacts and, therefore, creates a need for a mutual acculturation between the migrants and the host society. This research aimed to contribute to the study of immigrant adjustment in China by exploring the patterns of dietary acculturation among Russian immigrants residing in Beijing. The research was framed as an explorative qualitative case study, and employed Berry’s acculturation model as a theoretical basis. This model draws on the dichotomy between ethnic identification and acculturation in order to distinguish four strategies of acculturation: assimilation, separation, integration and marginalization. Acculturation strategies framework was applied to food preferences of Russian immigrants in three food-related contexts: everyday consumption, preparation, and New Year celebration. As a result, integration was defined as a predominant acculturation strategy of the group. However, it was also revealed that the patterns of dietary acculturation altered considerably depending on the context of consumption. Overall, the findings of the study demonstrated a complex, dynamic, and multidimensional nature of the acculturative processes. K eywords: dietary acculturation, acculturation strategies, Russian immigrants, China, food, immigrant adjustment.
Simulating stress-dependent fluid flow in a fractured core sample usingreal-time X-ray CT data

Abstract. Various geoscientific applications require a fast prediction of fracture permeability for an optimal workflow. Hence, the objective of the current study is to introduce and validate a practical method to characterize and approximate single flow in fractures under different stress conditions by using a core-flooding apparatus, in situ X-ray computed tomography (CT) scans and a finite-volume method solving the Navier–Stokes–Brinkman equations. The permeability of the fractured sandstone sample was measured stepwise during a loading–unloading cycle (0.7 to 22.1 MPa and back) to validate the numerical results. Simultaneously, the pressurized core sample was imaged with a medical X-ray CT scanner with a voxel dimension of 0.5 × 0.5 × 1.0 mm3. Fracture geometries were obtained by CT images based on a modification of the simplified missing attenuation (MSMA) approach. Simulation results revealed both qualitative plausibility and a quantitative approximation of the experimentally derived permeabilities. The qualitative results indicate flow channeling along several preferential flow paths with less pronounced tortuosity. Significant changes in permeability can be assigned to temporal and permanent changes within the fracture due to applied stresses. The deviations of the quantitative results appear to be mainly caused by both local underestimation of hydraulic properties due to compositional matrix heterogeneities and the low CT resolution affecting the accurate capturing of sub-grid-scale features. Both affect the proper reproduction of the actual connectivity and therefore also the depiction of the expected permeability hysteresis. Furthermore, the threshold value CTmat (1862.6 HU) depicting the matrix material represents the most sensitive input parameter of the simulations. Small variations of CTmat can cause enormous changes in simulated permeability by up to a factor of 2.6 ± 0.1 and, thus, have to be defined with caution. Nevertheless, comparison with further CT-based flow simulations indicates that the proposed method represents a valuable method to approximate actual permeabilities, particularly for smooth fractures (
Horizontal and vertical zoning of heterogeneities in the Hawaiian mantle plume from the geochemistry of consecutive postshield volcano pairs: Kohala‐Mahukona and Mauna Kea–Hualalai

Sr‐Nd‐Pb‐Hf isotopic compositions of postshield lavas from two pairs of Hawaiian volcanoes, Mauna Kea and Kohala (Kea trend) and Hualalai and Mahukona (Loa trend), allow for identification of small‐scale (tens of kilometers) heterogeneities in the Hawaiian mantle plume and provide constraints on their distribution. The postshield lavas range from transitional/alkalic basalt to trachyte and are enriched in incompatible trace elements (e.g., LaN/YbN = 6.0–16.2). These lavas are characterized by a limited range of Sr‐Nd‐Hf isotopic compositions (87Sr/86Sr = 0.70343–0.70365, 143Nd/144Nd = 0.51292–0.51301, and 176Hf/177Hf = 0.28311–0.28314) and have distinct Pb isotopic compositions (206Pb/204Pb = 17.89–18.44, 207Pb/204Pb = 15.44–15.49, and 208Pb/204Pb = 37.68–38.01) that correspond to their respective Kea or Loa side of the Pb‐Pb isotopic boundary. Mauna Kea lavas show a systematic shift to less radiogenic Pb isotopic compositions from the shield to postshield stage and they trend to low 87Sr/86Sr toward, but not as extreme as, compositions characteristic of rejuvenated stage lavas. Hualalai postshield lavas lie distinctly above the Hf‐Nd Hawaiian array and have much lower Pb isotopic ratios than shield lavas, including some of the least radiogenic values (e.g., 206Pb/204Pb = 17.89–18.01) of recent Hawaiian volcanoes. In contrast, comparison of Kohala with the adjacent Mahukona volcano shows that these older postshield lavas become more radiogenic in Pb during the late stages of volcanism. The isotope systematics of the postshield lavas cannot be explained by mixing between Hawaiian plume end‐members (e.g., Kea, Koolau, and Loihi) or by assimilation of Pacific lithosphere and are consistent with the presence of ancient recycled lower oceanic crust (±sediments) in their source. More than one depleted component is sampled by the postshield lavas and these components are long‐lived features of the Hawaiian plume that are present in both the Kea and Loa source regions. The depleted components in the postshield lavas, particularly as sampled at Hualalai, are different from the much more homogeneous component present in rejuvenated lavas. The geochemistry of the postshield lavas provides evidence for a bilateral symmetry to the plume where the compositional boundary between the Kea and Loa sources is complex and vertical components of heterogeneity are significant.
Joint analysis of continental and regional background environments in the western Mediterranean: PM 1 and PM 10 concentrations and composition

The complete chemical composition of atmo- spheric particulate matter (PM1 and PM10/ from a continen- tal (Montsec, MSC, 1570 m a.s.l.) and a regional (Montseny, MSY, 720 m a.s.l) background site in the western Mediter- ranean Basin (WMB) were jointly studied for the first time over a relatively long-term period (January 2010-March 2013).
Unexpected sudden death in a 14-year-old male: a case report and review of literature

The rare case described in this report was of a 14-year-old male who was previously healthy and unexpectedly died due to a massive intracerebral hemorrhage caused by acute monoblastic leukemia. The acute monoblastic leukemia was undiagnosed until he was presented in the ER 12 hours prior to death. An autopsy was performed, which showed that the extensive leukostasis and extramedullary leukemic infiltrate involved multiple organs, including lungs, heart, liver, spleen, kidneys, GI tract, thymus, lymph nodes and skin. Diffuse lymphadenopathy and multiple organomegalies were also identified. This case suggests that underlying acute leukemia should be considered as a differential diagnosis with careful physical examination when pediatric patients present with flu-like symptoms. Medical personnel are urged to be alert to fever, sore throat and weakness that may be characteristic of serious systemic diseases.
New boussinesq system for nonlinear water waves

In this paper, a new Boussinesq water wave theory is derived which can simulate highly dispersive nonlinear waves, their depth-varying velocities, and wave-induced currents, from very deep, but still finite, depths through the surf zone to the shoreline. Boussinesq scaling is employed. We removed the irrotationality assumption by using polynomial basis functions for velocity profile which are inserted into basic equations of motion. Keep terms up to the desired approximation level and solve the coupled weighted residual system together with vertically integrated mass equation. The computational cost is similar to normal Boussinesq theories although there are more unknown variables to be solved than that in normal Boussinesq models. Because we can reduce the number of the coupled equations by multiplying some coefficients and subtracting from each other which means the matix to be solved is in similar size as normal Boussinesq models. The models show rapid convergence to exact solutions for linear dispersion, shoaling, and orbital velocities; however, properties may be simultaneously and substantially improved for a given order of approximation using asymptotic rearrangements. This improvement is accomplished using the large numbers of degrees of freedom inherent in the definitions of the polynomial basis functions either to match additional terms in a Taylor series, or to minimize errors over a range. Future work will be focused on rotational performance in 2D model by including viscosity,breaking and turbulence.
Methane production potential of soil profile in organic paddy field

Mujiyo M. , Sunarminto B.H. , Hanudin E. , Widada J., Syamsiyah J. (2017): Methane production potential of soil profile in organic paddy field. Soil & Water Res., 12: 212−219. The use of organic fertilizers in the organic paddy/rice field can increase methane (CH4) production, which leads to environmental problems. In this study, we aimed to determine the CH4 production potential (CH4-PP) by a soil profile from samples using flood incubation. Soil properties (chemical, physical, and biological) were analyzed from soil samples of three different paddy farming systems (organic, semi-organic, and conventional), whilst soil from teak forest was used as the control. A significant relationship was determined between soil properties and CH4-PP. The average amount of CH4-PP in the organic rice field profile was the highest among all the samples (1.36 μg CH4/kg soil/day). However, the CH4 oxidation potential (CH4-OP) is high as well, as this was a chance of mitigation options should focus on increasing the methanotrophic activity which might reduce CH4 emissions to the atmosphere. The factor most influencing CH4-PP is soil C-organic (Corg). Corg and CH4-PP of the top soil of organic rice fields were 2.09% and 1.81 μg CH4/kg soil/day, respectively. As a consequence, here the mitigation options require more efforts than in the other farming systems. Soil with various amounts of Corg reached a maximum point of CH4-PP at various time after incubation (20, 15, and 10 days for the highest, medium, and the lowest amounts of Corg, respectively). A high amount of Corg provided enough C substrate for producing a higher amount of CH4 and reaching its longer peak production than the low amount of Corg. These findings also provide guidance that mitigation option reduces CH4 emissions from organic rice fields and leads to drainage every10–20 days before reaching the maximum CH4-PP.
A microeconometric analysis of household savings determinants in Morocco

Economic fluctuations, climate risk and a number of individual specific shocks leave households vulnerable to severe hardship in developing countries. Moreover, the credit and insurance markets are limited and the social coverage is weak. In this context, households saving is crucial to provide an insurance against the economic and social shocks. Additionally, a better knowledge of households saving behaviour could develop the potential to finance investments. This article provides an analysis of microeconomic factors which explain the household savings behaviour in Morocco by using a new survey. Household saving functions are estimated in order to test households' responses to income, monetary or non-monetary wealth and socio-demographic variables in urban and rural areas. Our results confirm that current income strongly affects the saving level whatever the home place. Surprisingly, the household’s size is significant only in the urban case : an additional person reduces the household saving. For the life cycle hypothesis, the results are not significant. Finally, we find that Moroccan women save more than men when we take into account the interaction between gender and income. Nevertheless, for highest income levels, we observe the opposite results. In the case of rural households, there is no statistically significant effect on saving behaviour from the ownership indicators of household’s lands or other real estate. The results suggest that the self financing of rural household activities may be due to the lack of access to formal financial intermediaries.
Is Noise Always Bad? Exploring the Effects of Ambient Noise on Creative Cognition

This paper examines how ambient noise, an important environmental variable, can affect creativity. Results from five experiments demonstrate that a moderate (70 dB) versus low (50 dB) level of ambient noise enhances performance on creative tasks and increases the buying likelihood of innovative products. A high level of noise (85 dB), on the other hand, hurts creativity. Process measures reveal that a moderate (vs. low) level of noise increases processing difficulty, inducing a higher construal level and thus promoting abstract processing, which subsequently leads to higher creativity. A high level of noise, however, reduces the extent of information processing and thus impairs creativity.
EFFECTIVENESS OF TELEPHONE-DELIVERED INTERVENTIONS FOR INCREASING PHYSICAL ACTIVITY LEVELS IN PERSONS WITH TYPE 2 DIABETES OR HYPERTENSION: A SYSTEMATIC REVIEW

Objective: Telephone calls can potentially be an accessible and cost-effective modality for delivering physical activity (PA) interventions to primary care patients. This review aims to evaluate the effectiveness of telephone counseling to increase PA levels in persons with type 2 diabetes (T2D) or hypertension. Methods: A systematic search (to May 2014) was conducted on the following databases, CINHAL, EMBASE, MEDLINE, Pub Med, and Psych INFO. Articles were included if they contained a control group, included participants with T2D or hypertension, implemented predominately a PA intervention, included PA as a primary outcome measure, and used telephone calls as a predominant delivery method for the intervention. Results: Thirteen articles that reported on eight studies were included in the final review. All eight studies assessed PA levels at the end of the intervention (post-intervention), and five studies assessed PA levels at follow-up. Post-intervention, 5/8 studies produced a significant effect on PA outcomes (with increases in PA favoring the experimental group). Large effect sizes (Cohen’s d>0.8) were calculated for three studies, and a medium (Cohen’s d: 0.5-0.79) and small effect sizes (Cohen’s d: 0.2-0.49) were calculated for one study. At follow-up, 3/5 studies produced a significant effect on PA outcomes. One study reported a large effect size and two studies reported a small effect size. Conclusions: Telephone calls show promise for delivering PA interventions for persons with T2D. No conclusions can be made regarding the effectiveness of telephone calls for persons with hypertension (only one study reported the number of patients with hypertension). Keywords: Physical activity, Exercise, Telephone, Type 2 Diabetes, Hypertension.
