Etching rate characterization of SiO2 and Si using ion energy flux and atomic fluorine density in a CF4/O2/Ar electron cyclotron resonance plasma

SiO2 and Si etching in a CF4/O2/Ar plasma has been carried out in an electron cyclotron resonance etcher over a wide range of conditions. The etch rate has been compared with the ion energy flux to the wafer surface, JiEi, and the atomic fluorine density in the gas phase, nF. It is found that the etch rate can be divided into two regimes by a critical value of nF/(JiEi), the ratio of the atomic fluorine density to the ion energy flux. The critical value can be determined from a contour plot of the etch rate as a function of the ion energy flux and the atomic fluorine density. The critical value of nF/(JiEi) for Si is higher than that for SiO2. For nF/(JiEi) higher than the critical value, the SiO2 etch rate linearly increases with the ion energy flux, and the Si etch rate shows a nonlinear increase with the ion energy flux. For nF/(JiEi) lower than the critical value, both SiO2 and Si etch rates linearly increase with the atomic fluorine density.
Amino acid survival in large cometary impacts

Abstract— A significant fraction of the Earth's prebiotic volatile inventory may have been delivered by asteroidal and cometary impacts during the period of heavy bombardment. The realization that comets are particularly rich in organic material seemed to strengthen this suggestion. Previous modeling studies, however, indicated that most organics would be entirely destroyed in large comet and asteroid impacts. The availability of new kinetic parameters for the thermal degradation of amino acids in the solid phase made it possible to readdress this question.

Title Prefrontal activation during and before solution of an eight-arm shuriken-shaped maze task presented on a touch screen: a near-infrared spectroscopy study

maze task presented on a touch screen: a near-infrared spectroscopy study Sub Title タッチスクリーン上に提示された, 8本の腕を持つ手裏剣形迷路課題の遂行中および遂行開始前における前頭前野活動 : 近赤外線分光法による検討 Author 宮田, 裕光(Miyata, Hiromitsu) 渡辺, 茂(Watanabe, Shigeru) 皆川, 泰代(Minagawa Kawai, Yasuyo) Publisher 慶應義塾大学大学院社会学研究科 Publication year 2010 Jtitle 慶応義塾大学大学院社会学研究科紀要 : 社会学心理学教育学 : 人間と社会の探究 (Studies in sociology, psychology and education : inquiries into humans and societies). No.70 (2010. ) ,p.125140 Abstract The present study using near-infrared spectroscopy (NIRS) examined prefrontal activation associated with maze-solving performance and preplanning in adult humans. The participants were required to solve an eight-arm shuriken-shaped maze, comparable to the one used for pigeons to behaviorally assess preplanning, by moving a target square to a goal square presented on a touchsensitive screen. The maze-solution phase was preceded by a 10-s preview phase during which the participants could observe but were not allowed to solve the maze. The participants, in contrast with pigeons, made few incorrect responses in trials in which the goal jumped to the end of another arm following the preview phase. The NIRS data revealed two-peak waveforms, with the first peak during the preview phase and the second one during the solution phase, most evidently in baseline trials. Significant increase in oxy-Hb was found near right dorsolateral prefrontal cortex (DLPFC) during the solution phase, while hemodynamic changes during the preview phase failed to reach statistical significance. The data suggest that, although human adults may have planned the solution of the maze during the preview phase, they needed to employ relatively small amount of cognitive resources throughout this task. Developmental and comparative perspectives for investigating neural correlates of preplanning are discussed.

Combined Study of UV/Visible Spectroscopy and Static Light Scattering on the Aggregation Behavior of Acid Red 266 in Aqueous Solution

The aggregation behavior of the azo dye Acid Red 266 has been investigated in pure water and in the presence of additional electrolyte (0.05 M NaCl) at 20 °C by UV/vis spectroscopy and static light scattering (SLS). The spectroscopic data were interpreted as a monomer/dimer equilibrium in the absence and presence of electrolyte. The equilibrium constants were determined as 20 000 ± 3 000 L mol-1 (in pure water) and 43 000 ± 4 000 L mol-1 (in 0.05 M NaCl), respectively. Although application of SLS revealed much larger species than dimers, the spectroscopic data were evaluated in terms of a monomer/dimer equilibrium to correct the light scattering data, for the first time, by the amount of residual monomers. This is possible because aggregates of this dye, reflecting the same local arrangement between the interacting molecules as in dimers, revealed no differences between dimers and higher multimers in the absorption spectra measured.1 Thus, the concentration of all aggregated species is represented by the .
Applicability of 0.01 M CaCl2 as a single extraction solution for the assessment of the nutrient status of soils and other diagnostic purposes

Abstract The applicability of 0.01 M CaCl2 solution as a single extraction agent for soils as a basis for fertilizer recommendation was tested on a variety of soils both from the Netherlands and from some tropical countries. Air‐dry soil samples were subjected to extraction with 0.01 M CaCl2 and to several conventional extraction procedures, and the results were compared. In the soil suspensions pH was measured, whereas in the extracts Na, K, Mg, P, different extractable N‐forms and Zn were measured. The values found in CaCl2 extracts are discussed in relation to results of other extraction procedures and as to their potential value in soil quality assessment. It is concluded that a single extraction procedure with 0.01 M CaCl2 can be applied for fertilizer recommendation purposes. The possibility of determining different extractable N‐forms (NH4, NO3, soluble organic N) significantly enhances the value of the method in predicting the N‐fertilizer needs. Furthermore it was found that the concentration of .
Binary Mixtures of Chlorobenzene and Cyclohexane Vapours Adsorbed under Dynamic and Static Conditions by Activated Carbon Beds

The adsorption of mixtures of chlorobenzene (C6H5Cl) + cyclohexane (c-C6H12) onto activated carbon U-03 has been examined at about room temperature. As shown by Stoeckli et al. (2002), combination of the Myers-Prausnitz-Dubinin theory (MPD) with the activity coefficients of the corresponding solid-liquid equilibrium led to a good correlation between the calculated and experimental mole fractions for the adsorption of binary mixture vapours by microporous solids under static conditions. The present study demonstrates the approach, which is based on an ideal adsorbed state (IAS). This can be employed for binary vapour mixtures such as chlorobenzene + cyclohexane under dynamic conditions in PSA (Pressure Swing Adsorption) and dynamic breakthrough experiments.
Thermochemical Data for Gaseous Monoxides

Values for standard enthalpies of formation and dissociation energies for gaseous diatomic monoxides have been selected by critical assessment of experimental data from the literature. Gibbs energy functions, (−(G○T −H○298)/T), and enthalpy functions, (H○T −H○298), have been calculated from literature values for molecular parameters. Computer methods of storage, processing and retrieval are described and the resulting data are given in tables 4 to 11.
Consumer Sentiment During the COVID-19 Pandemic

We analyze consumer sentiment with a novel survey of Thai and Vietnamese consumers conducted in May 2020, that is, shortly after the end of the immediate lockdown due to the COVID-19 pandemic. In a randomized control trial, we expose subgroups of the survey respondents to four di erent information treatments: (1) how their country ranks in a global survey on agreement or disagreement with the government's response to COVID-19, (2) how the country compares in a global survey on the appropriateness of the general public's reaction to the pandemic, (3) the negative unemployment outlook due to the pandemic, and (4) the positive e ects of social distancing for the spread of the virus. First, our results show that consumers are more optimistic if they expect higher GDP growth and trust the government in dealing with the crisis, whereas having stronger concerns about their household's nancial situation due to COVID-19 is related to less optimistic sentiment. Second, we nd that the information treatments only weakly a ect consumer sentiment. However, consumer sentiment is strongly a ected by treatment (1) and (2) when they go against respondents' previously held views. Finally, we discover large di erences between the two countries.

Purpose. This paper describes the concept of “strength of the work-life balance system” as a new and more advanced form of involvement in work-life issues, which lead to a stronger relationship with positive outcomes such as performance, commitment or satisfaction. Design/methodology/approach. From a theoretical point of view, and following Bowen and Ostroff (2004; 2016)’s framework of strength, all the features of a strong work-life balance system are described. We define the characteristics that allow the work-life balance system to create strong situations in which clear messages are sent to employees about what appropriate behavior is. Findings. Offering specific practices or specific types of support is not enough; a strong work-life balance system must also be in place. The strength of the system, which refers to the process, allows the firm to convey a consistent message about the content of the practices. Employees’ motivation, attitudes and behaviors towards work-life balance are highly dependent on how they interpret the signals from employers about the work-life balance system designed but also implemented. Practical implications. Future research and practitioners should pay more attention not only to design work life practices, but also to the implementation process in order not to fail in gaining all the positive outcomes related to work life balance, for employers and employees. Originality/value. This paper is the first step in the exploration of the importance of the implementation process of a work-life balance system, for a better contribution to organization positive outcomes.
A Complication-Based Comparison Between the Posterior and Direct Lateral Approaches to Total Hip Arthroplasty: A Single-Center Experience

Introduction Many approaches to performing total hip arthroplasty (THA) exist, primarily due to an insufficient amount of research that would favor one approach over the other. This study aimed to compare the risk of nerve injury, dislocation, Trendelenburg gait, and stem malposition between the direct lateral and posterior approaches to THA. Methods The study was a retrospective cohort study, and it was conducted in King Abdulaziz Medical City. It was directed toward adult patients who underwent THA from November 1, 2003, to November 1, 2018. All figures were obtained through the BESTCare system (ezCareTech, Saudi Arabia). Categorical variables were presented as frequencies and proportions. Quantitative variables were measured as mean and standard deviation. Fisher's exact test was used to compare the risk of complications between the two approaches. Results The posterior approach displayed a greater risk of stem malposition (p< 0.001) when compared with the direct lateral approach. However, neither approach showed a higher risk of dislocation, nerve injury, or Trendelenburg gait. Conclusions A higher risk of stem malposition was observed in the posterior approach, and there were no remarkable variances between the two approaches in the risk of dislocation, nerve injury, and Trendelenburg gait. Until more meticulous nationwide studies are available to provide evidence that would favor an approach over the other, the choice of surgical approach for THA remains to depend on the patient's characteristics and the surgeon's prior experience. Regardless of the approach, preoperative, intraoperative, and postoperative factors that increase the risk of complications should also be identified and addressed adequately.
Photoabsorption spectra of icosahedral fullerenes: A semiempirical approach

A semiempirical model has been used to predict the electronic photoabsorption spectra of five icosahedral fullerenes in the range C60–C720. The model parameters are first fixed in C60 by fitting its calculated spectrum to the available experimental data, and then conveniently adjusted to describe the larger fullerenes. The structures observed in the calculated spectra show a tendency to smooth π and σ plasmons as the fullerene size increases; however other finite-size features related to the particular geometry of these molecules are still visible at higher resolution. Some consequences of the strong electron screening effects on these spectra are discussed.
A study of chemical speciation of metals in aquatic bottom sediment of Aiba reservoir, Iwo, Nigeria

The species and total mean metal concentrations of some potentially environmental toxic metals (manganese (Mn), iron (Fe), copper (Cu), zinc (Zn), and lead (Pb)) in the sediments of Aiba reservoir were examined. The total mean value were in the order of Fe > Mn > Zn > Cu > Pb. The metal concentrations (mean ± standard deviation (SD) in ig/g dry weight) were Mn, 28 ± 0.88; Fe, 42.03 ± 1.11; Cu, 5.82 ± 0.21; Zn, 11.91 ± 0.37; and Pb, 0.44 ± 0.02. Some physico-chemical parameters of the bottom sediments were also measured and their average levels and range are pH, 6.2 to 6.6; conductivity, 104 ± 5 iScm-1 (50 to 170 iScm-1); water absorbency, 54.66 ± 2.17 (50 to 63.3). The speciation result revealed that high levels of these metals studied (Mn, Fe, Cu, Zn, and Pb) were associated with exchangeable and carbonate bound fractions, pointing out that they are in potentially available forms and may pose serious problems to the reservoir ecosystem. Key words : Bottom sediments, speciation, Aiba reservoir, metals.

This phenomenon indicates the potent synergistic beneficial effect of mixed diet to supply energy source.
Indoor Climate and the Performance of Ventilation in Finnish Residences

The purpose of the study was to gather information about the actual ventilation and indoor air quality and to evaluate the differences between houses and apartments with different ventilation systems. A sample of 242 dwellings in the Helsinki metropolitan area was studied over periods of no weeks during the 1988-1989 heating season. The mean air-exchange rates had a high variation (average 0.52 l/h, range 0.07-1.55 l/h). The ASHRAE minimum value of 0.35 l/h was not achieved in 28% of the dwellings. The air-exchange rates were significantly her in the houses than in the apartments (averages 0.45/0.64 l/h, p < 0.001); in the natural ventilation systems they, were slightly her than in the mechanical systems. The average temperature in the bedrooms was approximately 22 °C (range 18–27 °C), slightly but significantly higher in the apartment than in the houses. The average dust depositions were higher in the balanced ventilation systems than in the other systems. The median radon concentration was 82 Bq/m3 (range 5-866 Bq/m3); the Finnish target value of 200 Bq/m3 was exceeded in 17% of the houses but in none of the apartment. The measurements indicate that the indoor air quality in Finnish dwellings is not always satisfactory with reference to human health and comfort.

Effects of phosphorus fertilisation and harvesting stages on forage yield and quality of narbon vetch

Abstract The effects of five different phosphorus rates (0, 30, 60, 90 and 120 kg ha‐1) and three different harvesting stages (beginning of flowering, full flowering, and seed filling) on forage yield and quality of narbon vetch (Vicia narbonensis L.) were evaluated under the Mediterranean conditions of Turkey in 2005 and 2006 growing seasons. Dry matter (DM) yield, crude protein (CP), N, P, K, Mn, Cu, Fe, Zn, Ca, Mg, acid detergent fibre (ADF) and neutral detergent fibre (NDF) were determined. Phosphorus rates and harvesting stages significantly affectedmost of the quality components determined in narbon vetch. Phosphorus applications increased DM yield, CP, N, P, Ca and Mg contents, decreased K, Fe, ADF and NDF, and had no effect on Mn, Cu and Zn. Harvesting at the late stages caused a reduction in forage quality. Crude protein, N, P, K, Cu, Zn and Mg contents decreased with advancing stages, while Ca, ADF and NDF contents increased.
Effects of Surface Roughness on the Performance of Tangential Inlet Cyclone Separators

This study is carried out to investigate the effects of surface roughness on the flow field and cyclone performance. The flow inside the cyclone separator is modeled as a three-dimensional turbulent continuous gas flow with solid particles as a discrete phase. The continuous gas flow is predicted by solving the governing equations by using the Reynolds Stress turbulence model, and the modeling of the particle motions is based on a Lagrangian approach. The results of the numerical simulations are compared with experimental data as well as with the results of mathematical models. Analysis of computed results shows that increase of relative roughness due to corrosion, wear, or accumulation of particles on the inner walls considerably influences the tangential velocity, cyclone separation efficiency, and cyclone pressure drop especially for high inlet velocities. Decreases in cyclone collection efficiency and pressure drop with the increase in surface roughness are found to be more pronounced for high values of relative roughness.
Isolation, biochemical and molecular detection of Bacillus subtilis and Bacillus licheniformis from the digestive system of rainbow trout (Oncorhynchus mykiss) and its inhibitory effect on Aeromonas hydrophila.

Our study was focused on characterization of dominantBacillus bacteria isolated from the digestive tract of Oncorhynchus mykiss. After 8 weeks, the fish fed with probiotic-free diet were dissected under strictly controlled conditions. Fish intestines were eviscerated and its content diluted to 10−4 using Ringer solution. Two isolated bacteria were Gram-positive, catalase-positive, and oxidase-negative, based on the biochemical tests. A mixed of the two strains was the most efficient isolates determined inO. mykiss. Molecular characterization using PCR-Ribotyping was carried out using sequencing the 16S rRNA gene of both strains, which isolated two bacteria, Bacillus subtilis Ahari.H1 and B. licheniformis Ahari. H2. The isolated bacteria could tolerate 0.3% bile salt and non-hemolytic in nature. They also showed resistance to pH at 2.5 and 4 for acid test and 2.3 and 7 for gastric juice, pepsin and trypsin. It is concluded that the efficiency of the isolated probiotics can be candidates as probiotic in fish culture. It was unveiled that these strains can successfully diminish Aeromonas hydrophila pathogenicity in rainbow trout.
