Coupled heat transfer characteristics on gas-solid reacting interface in carbon-oxygen dissociating environment for spacecraft entry flow

Planetary spacecrafts, such as return capsules and Mars entry vehicles, enter the atmosphere at extremely high speeds, and therefore high-enthalpy dissociated aerodynamic environment occurs around the heat shield (Gnoffo, 1999). Such severe environment brings complex interface heat transfer processes between the gas and solid domains. Moreover, deep space exploration, such as hypersonic Mars entry mission, causes an additional carbon-oxygen (C-O) reacting environment, which further brings some new challenges to the evaluation of interface heat transfer characteristics (Reynier, 2014). Accurate and reliable prediction of interface heat transfer is the premise and basis for effectively ensuring the safety of the spacecraft thermal protection system (TPS), reducing design redundancy and increasing the effective payload (Duffa, 2013). With the continuous and in-depth development of high-performance computing, using the numerical technology to characterize fluid mechanics, structural heat transfer, interface chemistry and their interaction has become an effective way to solve this problem (Milos and Rasky, 1994). Early researches on interface heat transfer characteristics were done by solving the compressible gas dynamics equations with simple mathematical closure on the solid surface (Wright, et al., 2010).

The Impact of Competitive Strategy and Intellectual Capital on SMEs Performance

This study aims to examine the impact of competitive strategies and intellectual capital on the performance of Small and Medium Enterprises (SMEs). The research sample is the owners of SMEs in the Banten region. The number of final samples obtained that can be included in the test is as many as 181 respondents of SME owners or 60.33% of the total intended respondents. The data analysis technique used is regression with structural equation models. The results showed that the Competitive Strategy proved to have a positive effect on the success of SMEs. The choice of the right competitive strategy can improve SME performance. Intellectual Capital Management is also proven to have a positive effect on the success of SMEs. The greater the Intellectual Capital, the more it will encourage SMEs to perform better. The implication of the results of this study is that in order to improve the competitiveness and success of SMEs, it is necessary to choose the right competitive strategy and manage their intellectual capital well.

CDS-Based Topology Control in FANETs via Power and Position Optimization

In a flying ad hoc network (FANET), reliable maintenance of topology confronts a huge challenge due to the highly time-varying connectivity between flying nodes. Aiming at mitigating this issue, this letter proposes a connected dominating set (CDS) based topology control mechanism iteratively for the FANETs by solving a jointed optimization problem on adjusting the node’s transmission power and position during the construction of CDS. In particular, a well-tailored group of the topology constructing and maintaining algorithms are developed with a time-discretized approach. Simulation results show that the proposed mechanism has a better performance with respects to overheads and network stability than a general particle swarm optimization (PSO) algorithm, especially in a typical swarm pattern for unmanned aerial vehicle (UAV) team.
Synchronization of Identical Oscillators Under Matrix-Weighted Laplacian With Sampled Data

In this paper, we study the synchronization problem of identical oscillators interacting via matrix-weighted couplings under both undirected and directed graph topologies. In contrast to the existing mechanism which makes use of the instantaneous and the derivative information of the relative state, the sampled-data technique is utilized to tackle the case when the derivative information of the relative state is unavailable. Necessary and sufficient conditions depending on the coupling gains, the sampling period, and the spectra of the matrix-weighted Laplacian, are established for achieving synchronization of the oscillators under undirected and directed graph topologies. The constraints on the matrix weights that guarantee the desired spectral property of the Laplacian are also investigated. Finally, simulation results are given to verify our theoretical results.
Does Life Satisfaction Mediate the Relationship Between Mood and Daydreaming Frequency?

Recent research has highlighted the significance of daydreaming, a temporary separation from reality that focuses on an individual’s thoughts (e.g., Giambra & Traynor, 1978; Golding & Singer, 1983; Mar, Mason, & Litvak, 2012). Killingsworth and Gilbert (2010) found that people’s minds wander 46.9% of the time. However, the potential relationship between daydreaming frequency, life satisfaction, and mood has received little attention in the literature. Although some researchers have suggested that daydreaming precedes a negative affect (Killingsworth & Gilbert, 2010), others have demonstrated that one’s mood leads the mind to wander (Smallwood, Fitzgerald, Miles, & Phillips, 2009). The current study further explored the relationship between positive mood and daydreaming frequency by assessing whether life satisfaction may serve as a mediator. Although daydreaming and mind-wandering may be considered two different constructs, the current literature has often used these terms interchangeably. For instance, theorists have defined daydreaming in three predominant ways—as fanciful desired wishes, as thinking unrelated to an ongoing activity (mind-wandering), or as unintended mental content that comes to mind effortlessly (Klinger, 2009). Rather than defining daydreaming as a unitary construct that either includes or excludes mind-wandering, Klinger (2009) suggested that daydreaming be defined as nonworking thought that is spontaneous or fanciful. In this way, daydreaming includes mind-wandering. ABSTRACT. The current study tested to see if life satisfaction mediates the relationship between positive mood and daydreaming frequency. Two nonexperimental studies were conducted in which participants completed a questionnaire that assessed their positive mood, life satisfaction, and frequency of daydreaming. In Study 1, including 170 collegiate students, statistically significant results supported our correlational hypotheses between positive mood and life satisfaction (r = .67, p < .001), life satisfaction and daydreaming frequency (r = -.22, p = .002), and positive mood and daydreaming frequency (r = -.27, p < .001). However, the proposed mediational model, that life satisfaction mediated the relationship between positive mood and daydreaming frequency, was not supported because the negative relationship between positive mood and daydreaming frequency remained statistically significant when life satisfaction was added to the regression equation (ß = -.22, SE = .07; 95% CI [-.30, -.01]; p = .033). Study 2, including 102 adults, aimed to increase the reliability and generalizability of Study 1. Results from Study 2 also did not support the mediational role of life satisfaction. However, the results of Study 2 also demonstrated a negative relationship between positive mood and daydreaming frequency (r = -.35, p < .001), even when life satisfaction was included in the regression equation (ß = -.39, SE = .08; 95% CI [-.45, -.13]; p < .001). We discuss possible age and gender effects, and future directions of research.
Dynamics of hematological parameters in female lambs during the first four months of life

Important physiological changes affect the blood profile of ruminants during the growth phase, but few studies approach the factors involved in these dynamics in lambs. The aim of this study was to characterize the dynamics of hematological parameters, of total plasma protein (TPP), and of fibrinogen in healthy female lambs during the first four months of life. Blood samples of 35 female lambs were collected at 30, 60, 90, and 120 days old to perform the complete blood count (CBC). The erythrocyte and leukocyte parameters, TPP, and fibrinogen were determined. The means for total red blood cell (RBC) counts at 60 and 120 days differed (P 0.05) between the ages (mean of 1.8) but higher than the reference value for adult sheep (0.5). The initial mean for eosinophil counts (2 cells µL-1) was lower (P < 0.05) than all subsequent ones, and the monocyte count showed the lowest level (P < 0.05) at 120 days (232 cells µL-1). The mean for TPP at 60 days (6.4 g dL-1) was higher (P < 0.05) than the other ages. Except for band neutrophil and basophil counts, and fibrinogen concentration, the hematological parameters and the TPP of female lambs are influenced by age until four months of life and differ from the reference intervals established for adult sheep. Therefore, the interpretation of CBCs performed in female lambs should be made on the basis of age group-specific reference intervals.
How mushrooms tend to break through the genetic dead end

Genes, genetics, genomics, and the roles of mushrooms and toadstools in the global carbon cycle are reviewed here. Fungi – similar to wood eating insects – are the main decomposers (a type of consumers or heterotrophs), and consequently recyclers of biomass produced by photosynthetic organisms (i.e., the producers or autotrophs). Photosynthesis is driven by the solar energy day by day (of Photoautotrophs) (i.e., primary producers), and night by night (of Chemoautotroph bacteria) for billions of years. Only photosynthetic organisms can produce organic materials in the Earth to supply food and feed to the Heterotrophs (animals, including Human), and Saprotrophs (i.e., decomposers) including fungi and bacteria. The crucial excess oxygen the photosynthesis produces oxygenates and maintains the life in the Earth. Mushrooms were found to have 100-1000 times smaller genomes than plants or animals, however, enormous genome expansions of Armillarias (Eng./Hung.: honey mushrooms / tuskogombak) have indicated recently that fungi tend to break out from their closed evolutionary dead end. Comparative genome analyses of Polyporales mushrooms have recently identified an ongoing transitioning evolutionary stage from white-rot (WR) towards brown-rot (BR) life style with loss of genes encoding enzymes to decay cell wall components of plants and trees including cellulose, hemicellulases, lignin (the three together also called lignocelluloses), and pectin. In the case of lignin, ligninase enzyme genes were evolved only in fungi to decay lignin of plants. A tripartite symbiosis among achlorophyllous (i.e., parasitic) mycoheterotrophic plants ↔ mycorrhizal fungi ↔ and autotrophic green plants were re-discovered recently. Here we review all of these new achievements in the research of Dicaria true fungi (Eumycota) of both Ascomycota (Eng./Hung.: Sac fungi / Tomlősgombak) and Basidiomycota (Eng./Hung.: Club fungi / Bazidiumosgombak) with special emphasis on genes, genetics, genomics and evolutionary relationships.
How Can We Engage Students with Digital Objects? A Numismatic Case Study.

ABSTRACT:This paper reflects on a learning and teaching project undertaken at a large Australian university which investigated classroom use of online numismatic resources. It describes four methods of using coins in online, traditional, and blended units, discusses successes and failures, and offers recommendations for adapting the ideas elsewhere. Topics include threshold concepts, online and face-to-face discussions concerning coins, how lecture information might be supplemented with eBooks, and online quizzes. Coins showed surprising adaptability. The overall response from students and academics was positive. Trials were most successful when material aligned with specific assessment tasks.
Selected root plant supplementation reduces indices of exercise-induced muscle damage: A systematic review and meta-analysis.

This systematic review and meta-analysis examined the effects of selected root plants (curcumin, ginseng, ginger and garlic) on markers of muscle damage and muscular performance measures following muscle-damaging protocols. We included 25 studies (parallel and crossover design) with 353 participants and used the PEDro scale to appraise each study. Forest plots were generated to report on standardised mean differences (SMD) and p-values at 24 and 48 hours following the muscle-damaging protocols. The meta-analysis showed that the supplemental (SUPP) condition showed significantly lower levels of indirect muscle damage markers (creatine kinase, lactate dehydrogenase and myoglobin) and muscle soreness at 24 hours and 48 hours (p < 0.01) than the placebo (PLA) condition. The inflammatory markers were significantly lower for the SUPP condition than the PLA condition at 24 hours (p = 0.02), although no differences were identified at 48 hours (p = 0.40). There were no significant differences in muscular performance measures between the SUPP and PLA conditions at 24 hours and 48 hours (p > 0.05) post-exercise. According to our qualitative data, a number of studies reported a reduction in oxidative stress (e.g., malondialdehyde, superoxide dismutase) with a concomitant upregulation of anti-oxidant status, although other studies showed no effects. Accordingly, selected root plants minimised the level of several biomarkers of muscle damage, inflammation and muscle soreness during periods of exercise-induced muscle damage. However, the benefits of these supplements in ameliorating oxidative stress, increasing anti-oxidant status and accelerating recovery of muscular performance appears equivocal, warranting further research in these outcome measures.
Theoretical Correlation of Elemental Distribution of Nd and Pr in Ce-Fe-B Microstructure With Hard Magnetic Properties

Relatively resource-rich but property inferior-Ce-Fe-B magnet can be improved by partial replacement of Ce by Nd and/or Pr. In addition to the amount of Nd/Pr, their distribution profile in microstructure plays an important role. From our first principles density functional theory (DFT) calculation, the substitution energy of Ce by Pr/Nd is negative in Ce2Fe14B (2:14:1) while that for laves phase, CeFe2 is positive, implying that Nd/Pr stabilize 2:14:1 and suppress the formation of the CeFe2 phase. Micromagnetic simulation indicates that homogenized distribution of Nd/Pr improves squareness of demagnetization curve, while core (Ce-rich)-shell (Nd/Pr-rich) 2:14:1 grain structure enhances coercivity. Magnetic properties of Ce-Fe-B can be optimized by manipulating distribution profile of chemical element in microstructure based on their subtle difference in thermodynamic property, which is an effective pathway to design optimized chemical composition and processing route for high-performance magnet.
Semantic Reconstruction of Beauty and Makeup for Young Females: The Phenomenological Study

The concept of beauty is closely linked to gender in contemporary society; in this study, the concept of beauty was explored by the use of phenomenological techniques. For this purpose, an in-depth semi-structured interview was conducted among 35 young female students in Tehran. the sample of study was chosen by theoretical sampling model and the interviews were continued up to the point of gaining theoretical saturation.After extracting the basic, secondary and intermediate concepts, the three main categories were defined as: general areas of beauty and signs, makeup and consumption, and mediaand the need for beauty and make-up. The results of this study indicate that makeup is defined as an important activity for young girls. Beauty and makeup are intertwined with people's life plans and are regulated by them; that is, the amount and manner of makeup of female students changes with their understanding of the culture of different environments, types and gender of the audience, the level of communication and type of activity. It can be stated that makeup allows girls to have multiple social relationships. In analyzing and interpreting the interviews, a wide range of reasons, such as increasing social capital, coercion or group ambiguity, building a new and self-identifying identity, and increasing self-confidence were identified for the explaination of why makeup is used.
Effect of genotype on slaughtering performance, blood analyses and meat quality of laying hens reared in different conventional cage densities

The aim of the study was to evaluate the effects of genotype on slaughtering performance, blood analyses and meat quality of laying hens reared in different conventional cage densities. Laying hen flocks consisted of 180 Novogen White, 180 ATAK-S and 180 ISA-Brown at 72 weeks old reared in different conventional cage densities (312.50 cm2/hen and 468.75 cm2/hen). In the trial, one bird per each replica (9 in replica) were selected from every treatment (6 in treatment, 54 birds in total), and their body weights were weighed. Then, they were slaughtered and the carcass traits and some organs were weighed. Also, the blood and breast meat samples were taken for biochemical and meat analyses. In general, the ISA-Brown and ATAK-S strains received higher values than the Novogen White strain in terms of carcass traits. Also, according to stress parameters, it was observed that ISA-Brown strain was more resistant than others in high cage density. Moreover, the bacterial count and meat quality results of hens, the ISA-Brown strain is better than other strains. However, the texture analyses results of the Novogen White strain are better than ISA-Brown and ATAKS strains. As a result, the meat quality of the laying hens can be affected at different levels depending on the genetic structure of the chickens and the cage density of which they are reared.
Anti-inflammatory properties of combined aquatic extract of Ferulago angulata boiss with aerobic exercise on pro-inflammatory indices in obese males

Background: The application of supplements, herbal extracts, and exercise training for treatment of diseases and reducing chronic inflammation has been increased progressively among people. Thus, the aim of this investigation was to study the combined aquatic extract of Ferulago angulata boiss with aerobic exercise on pro-inflammatory indices in obese males. Materials and Methods: In this semi-experimental study, forty young obese men (mean and standard deviation of age 34.59 ± 2.24 years, body mass index (BMI) 33.14 ± 2.75 kg/m2) were selected by purposed sampling and were randomly divided into four equal groups (n = 10), training, training-supplementation, supplementation, and control. Participants in the supplementary groups received 50 mg/ml F. angulata extracts daily for 12 weeks. Aerobic training program included 12 weeks of training, 3 sessions/week, and each session was 20 min at 60%–%–70% of maximal oxygen consumption. Blood samples were taken from the participants 48 h before and after the intervention in fasting state. Data were analyzed using dependent t-test, one-way analysis of variance, and post hoc Tukey test at a significant level of P < 0.05. Results: After 12 weeks of exercise and supplementation, levels of interleukin (IL)-6 (P = 0.001), IL-18 (P = 0.03), IL-1 β (P = 0.001), tumor necrosis factor alpha (P = 0.001), weight (P = 0.001), BMI (P = 0.001), body fat percent (P = 0.001), and waist-hip ratio (P = 0.001) decreased significantly and the mean changes of these indicators in training + supplementation group were significantly augmented as compared to the other three groups. Conclusion: It appears that aerobic training plus F. angulata extract consumption have better effect on improvement of serum inflammatory factors in obese young men.
Effect of temperature on hydroxyl carbonated apatite from ash bagasse

Silica–based bioactive material can promote the nucleation of hydroxyl carbonated apatite (HCA) which roles on bone mineralization processes. The sol–gel synthesis produces nanoparticle. The small particle increases the surface area of particle that is known has high bioactivity. Sintering temperature affect properties and characteristics of the glass. The aims of the research was to know the effect of sintering temperature on HCA formation of nano bioactive silica from ash bagasse. The study was a laboratory experimental with control group post–test only design. ilica derived from sugarcane bagasse was used as a source of silica to synthesize bioactive glass and sodium silicate as a precursor. Sintering temperatures are 1 000 C and 1 500 C. Polysaccharide from seaweed was used as a binder to make plates from the bioactive glass. The plates were immersed in simulated body fluids (SBF) for 2 h, 12 h and 24 h. HCA formation was observed with Scanning Electron Microscope (SEM) and Forier Transform Infra–Red (FTIR). Two way anova and LSD test. The result of research shows that there were significantly different on HCA formation with variety of sintering temperature. Soaking time affects number and velocity of HCA formation. High sintering temperature cause increase HCA formation, but its formation is slower. The condition caused by crystal formation which produce bond more stable.
