A Mindfulness-Based Brain-Computer Interface to Augment Mandala Coloring for Depression: Protocol for a Single-Case Experimental Design

Background The regular practice of mindfulness has been shown to provide benefits for mental well-being and prevent depression relapse. Technology-mediated interventions can facilitate the uptake and sustained practice of mindfulness, yet the evaluation of interactive systems, such as brain-computer interfaces, has been little explored. Objective The objective of this paper is to present an interactive mindfulness-based technology to improve mental well-being in people who have experienced depression. The system, Anima, is a brain-computer interface that augments mandala coloring by providing a generative color palette based on the unfolding mindfulness states during the practice. In addition, this paper outlines a multiple-baseline, single-case experimental design methodology to evaluate training effectiveness. Methods Adult participants who have experienced depression in the past, have finished treatment within the last year, and can provide informed consent will be able to be recruited. The Anima system, consisting of 2 tablets and a nonintrusive mental activity headband, will be delivered to participants to use during the study. Measures include state and trait mindfulness, depression symptoms, mental well-being, and user experience, and these measures will be taken throughout the baseline, intervention, and monitoring phases. The data collection will take place in the form of a questionnaire before and after each mandala-coloring session and a semistructured interview every 2 weeks. Trial results will be analyzed using structured visual analysis, supplemented with statistical analysis appropriate to single-case methodology. Results Study results will offer new insights into the deployment and evaluation of novel interactive brain-computer interfaces for mindfulness training in the context of mental health. Moreover, findings will validate the effectiveness of this training protocol to improve the mental well-being of people who have had depression. Participants will be recruited locally through the National Health Service. Conclusions Evidence will assist in the design and evaluation of brain-computer interfaces and mindfulness technologies for mental well-being and the necessary services to support people who have experienced depression.

MULTIVARIATE PRINCIPAL COMPONENT ANALYSIS OF MORPHOLOGICAL TRAITS IN WEST AFRICAN DWARF GOATS

Multivariate analysis are important tools when considering all variables simultaneously. Principal component analysis using morphological variables of the West African Dwarf goats of Nigeria were carried out based on age and sex. A total of 250 goats, comprising of 143 does and 107 bucks, were used for this study. Data were collected from 10 morphological traits, including; body weight (BWT), body length (BL), height at wither (HW), rump height (RH), paunch girth (PG), heart girth (HG), ear length (EL), tail length (TL), horn length (HoL) and neck circumference (NC). Data collected were subjected to analysis procedures of SPSS (2011) statistical programme. Majority of the goats sampled were female indicating goat keepers’ preference for female than male for herd multiplication. Results of the ANOVA obtained revealed that sex had significant (P 0.05) effect on tail length. PC1 and PC2 were extracted for all the ages of the goats, totaling to 68.798 %, 53.833 %, 47.302 % and 51.880 % respectively, of the total variances explained.
The heat capacity of pure silicon and germanium and properties of their vibrational frequency spectra

Abstract Heat capacities of pure silicon and germanium have been measured between 2.5° and 300°K. The estimated accuracies of the measurements are ±0.5% for 10° 20°K. The results for silicon were anomalous in the region T <7°K; it is suggested that this behaviour resulted from adsorption and desorption of exchange gas in the calorimeter vessel. No anomalies were observed in the measurements on germanium; their accuracy at the lowest temperatures is estimated to be ±2%. The results for both substances are significantly different from previously published values. The temperature variation of ΘD of both silicon and germanium below about T= ΘD/3 is consistent with general harmonic theory, but at high temperatures ΘD decreases with increasing temperature. This appears to be a clearly marked anharmonic effect of a type that cannot be explained by change of volume alone. The results for T < ΘD/3 are therefore extrapolated to high temperatures to give a heat capacity consistent with h.
On the Influence of the Morphological Structure on the Liquid Crystalline Behavior of Liquid Crystalline Side Chain Block Copolymers

The influence of the morphological structure on the phase behavior of a liquid crystalline side chain block copolymer has been investigated using SAXS, DSC, TEM, and low-angle electron diffraction. All samples of poly[styrene-block-2-((3-cholesteryloxycarbonyl)oxy)ethyl methacrylate] (PS-b-PChEMA) show a phase separation between the two blocks. An influence on the phase structure of the liquid crystalline subphase exerted by the morphological structure was observed. It was found that in the case of those samples where the liquid crystalline subphase is not continuous (spheres), only a nematic phase is seen, whereas in all samples in which there is a continuous liquid crystalline subphase, the smectic A phase of the homopolymer is formed
Excimer laser photochemistry of silane-ammonia mixtures at 193 nm

The ArF excimer laser induced photochemistry of silane-ammonia mixtures has been studied with molecular beam sampling mass spectrometry. The observed products include disilane, trisilane, and all possible aminosilanes, SiH{sub x}(NH{sub 2}){sub 4-x}, x = 0-3. These products are formed under steady-state photolysis conditions and under single-laser-pulse conditions. A mechanism for the formation of these species is proposed and quantitatively evaluated.
Combustion Study of Synergism of Urea-Sodium Polymetaphosphate on the Flame-Retardancy of a Cotton Fabric Monitored by TG

The synergism of sodium polymetaphosphate- urea on the flammability of a cotton fabric (woven, plain 144 g/m2, the number of yarns 21 per 10 mm) has been investigated in this study. After impregnation with suitable individual additives and/or their appropriate admixed formulation onto the fabrics, their flammability has been assessed by using the described procedure. In this study the flame spread tests comply with thermogravimetry's data. Explanation of the synergism with regard to the thermal analysis illustrated moderately effect of sodium polymetaphosphate to show flame-retardancy due to the confinement of phosphate's activity in the polymeric inorganic chain, however this effect increased by using urea.
Field Pea Growth and Nutrient Uptake: Response to Tillage Systems and Nitrogen Fertilizer Applications

Abstract A two-year [1999, 2001] study of field pea (Pisum sativum L.) in rotation with small grain was conducted on a Fargo clay soil [fine, smetitic, frigid, Typic Epiaquert] to determine the influence of tillage system [fall PLOW, fall CHISEL PLOW, fall DISK, and NOTILL] and spring applied nitrogen fertilizer rates [0, 45, 90, and 135 kg ha−1] on dry matter production at three growth stages, and nitrogen–phosphorus–potassium [NPK] concentration and uptake. Plants were sampled at first flower [code 203] after 870 GDD and maximum dry matter production [code 208] after 1364 GDD. Seed was harvested for yield [code 303] after 1692 GDD. Dry matter production at flower stage 203 averaged 2400 kg ha−1 the first year and 1960 kg ha−1 the second year with the PLOW system producing the lowest dry matter in both years. Applications of nitrogen fertilizer at the high rate increased dry matter from 500 to 700 kg ha−1. Dry matter at stage 208 in 2001 ranged from 4260 kg ha−1 without fertilizer nitrogen applied, to 6360 kg ha−1 with 135 kg ha−1 of nitrogen fertilizer applied. In contrast to the earlier stage, the PLOW system produced the greatest total dry matter production at stage 208. Minimum pea seed yield, stage 303, averaged 2740 and 2410 kg ha−1 without any nitrogen fertilizer applied in 1999 and 2001. Maximum seed yields at harvest [3530 kg ha−1 in 1999 and 3140 kg ha−1 in 2001] were obtained only when 135 kg ha−1 nitrogen fertilizer was applied. Average seed yields were not always significantly different between tillage systems, but the CHISEL PLOW and DISK were consistently higher than PLOW or NOTILL at all nitrogen fertilizer rates. This research provided estimates of the amount of NPK nutrients required to maximize field pea production under various tillage systems and nitrogen fertilizer rates at various growth stages. When averaged across years, nitrogen fertilizer rates, and tillage systems, concentrations of N, P, and K were measured at 3.0, 0.30, and 2.6% at stage 203, with 2.4, 0.23, and 1.5% at stage 208 and finally the seed [stage 303] at 3.4, 0.38 and 1.2%. The pea plant required 0.031 kg N, 0.0032 kg P, and 0.027 kg K for each kilogram of plant dry matter produced by flowering stage 203. By stage 208 when the pea plant has reached maximum dry matter production, the nutrient requirement was 0.023 kg N, 0.0025 kg P, and 0.0162 kg K to produce 1 kg of plant material. By harvest, stage 303, the nutrients removed by the seed were 0.034 kg N, 0.0041 kg P, and 0.0115 kg K for each kilogram of seed produced. This study indicated that adequate nitrogen (derived from the soil, through N fixation or applied as fertilizer) was equally if not more important than tillage system and this management practice must be included in the overall plan for maxim field pea production in the Northern Great Plains.
Polymeric Pseudo-Liquid Membranes from Poly(2-ethylhexyl methacrylate)

Novel liquid membranes, which are named polymeric pseudo-liquid membranes, were constructed, using poly(2-ethylhexyl methacrylate), which showed rubbery state under operation conditions, as a membrane matrix. Dibenzo-18-crown-6 (DB 18C6) was adopted as a model transporter and membrane transport performance through those polymeric pseudo-liquid membranes was investigated, adopting KCI as a model substrate. Poly(2-ethylhexyl methacrylate), P2EHMA, gave self-standing liquid membranes under the experimental conditions, of which operation temperature was above its glass transition temperature. The polymeric pseudo-liquid membranes showed transport ability of KCI. The flux value was linearly increased with the increase in DB 18C6 content in the membrane and the membrane transport ability was greatly dependent on not only the molecular weight of membrane matrix, P2EHMA, but also the operation temperature. The present paper suggested that polymeric pseudo-liquid membranes are applicable to membrane separation as one of liquid membrane transport systems.
Can Global Sourcing Strategy Predict Stock Returns?

Problem definition: Whereas firms are increasingly relying on sourcing globally as a key constituent of their supply chain strategy, there is no empirical evidence on whether investors of these firms adequately reflect firms’ global sourcing strategy (GSS) in their stock-valuation process. In this paper, we empirically test whether stock market participants are efficient in doing so. Methodology/results: Using the empirical asset-pricing framework, we find that information concerning firms’ GSS strongly predicts their future stock returns. We compile a transaction-level imports database for U.S.-listed firms and construct measures for five widely studied GSS aspects in the operations management literature: the extent of global sourcing, supplier relationship strength, supplier concentration, sourcing lead time, and sourcing countries’ logistical efficiency. For each measure, we examine returns of a zero-cost investment strategy of buying from the highest and selling from the lowest quintile of that measure. Collectively, these investment strategies yield an average annual four-factor alpha of 6%–9.6% (6%–13.9%) with value (equal)-weighted portfolios. Their return predictability is incremental over other operations- and cost arbitrage–motivated predictors, such as inventory turnover, cash conversion cycle, and gross profitability; is persistent across different supply chain positions; and is robust to alternate risk models, subsamples, and empirical specifications. Together, our results indicate that the GSS measures embody independent information about firms’ future profitability, and this information is mispriced by market participants, leading to predictable returns. In accordance with this mechanism, we find that the GSS measures strongly predict both firms’ future earnings and the surprise in market reactions around the earnings announcement days. Managerial implications: The robust return predictability of our GSS measures suggests that investors are not fully incorporating GSS-related information in their stock valuation frameworks. Therefore, our results call for greater investor education on global sourcing and better dissemination of global-sourcing information so as to mitigate valuation inefficiency.

Impact of Ozone on Morphological, Physiological, and Biochemical Changes in Cow Pea (Vigna unguiculata [L.] Walp.)

Morphological and biochemical responses to Acute Ozone Exposure (AOE) by Vigna unguiculata (L.) Walp. cultivar variety CO6 was studied. Plants were grown in controlled conditions and exposed to ozone at 40, 50, 60, 70, and 80 ppbv (T1-T5) for 15 min twice a day. Variation among shoot and root length, shoot-root ratio, fresh (FW), dry (DW) weight, leaf area (LA), leaf area ratio (LAR), number of guard cells (G), epidermal cells (E) (abaxial and adaxial), stomatal index (SI), chlorophyll a and b, total chlorophyll (TC), chlorophyll a/b ratio, chlorophyll protein ratio (CPR), ascorbic acid (AA), total phenol (TP), Proline (Pro), nitrate reductase activity (NRA) and Urease activity (UA) were measured in control and ozone-treated plants. The ozone treatment resulted in increase in dry weight, shoot length, leaf area, and number of epidermal cells, stomata and total chlorophyll on exposure up to 60 ppbv. Nitrate Reductase (EC: 1.6.6.3) and Urease (EC: 3.5.15) activities were inhibited by ozone.

Holistic Identity of Language Teachers: A Grounded Theory Study

It is one of the major areas of interest within the field of educational research to examine the role of teachers, their professional accomplishment and influential factors affecting or inhibiting the practice; of which, the study of teacher identity has taken on fundamental property. Thus, the present study explored different aspects of a language teacher identity which led to the development of the theoretical framework of Holistic Identity of Language Teachers (HILT) based on the grounded theory. The data were collected in semi-structured individual interviews from 64 teachers in Iran. Employing a version of Strauss and Corbin’s (1998) coding paradigm, emerged a framework of a set of categories in terms of ‘process’ (i.e., becoming a teacher) as well as the grounding categories of ‘Persona Grata’ and ‘Public Persona’, resulted in the core category of ‘Teacherality’, along with three categories of ‘Navigating Strategies’, ‘Conditional Contributors’, and ‘Contextual Patterns’. The final consequence of the framework is ‘Actual Teaching Approach’, referring to the eventual phenomenon of the evolutionary continuum of being a holistic language teacher. The most obvious finding of the study refers to the emergent as well as evolutionary nature of HILT. Following the interplay between self and society in emergence of HILT, the schema was proposed to round up all revealed and unnoticed aspects of language teacher identity which can be implemented operationally to redefine, highlight, and activate its unprecedented role in an Iranian context.
Soft x-ray emissions from laser plasma of cryogenic mixture targets

Soft x-ray spectral radiation from Xe–CO2 mixture cryogenic targets with a Xe mole fraction of 0% (pure CO2) to 100% (pure Xe) irradiated by a 1 μm pulse laser at a laser intensity IL of 0.3–1.0×1012 W/cm2 has been observed. The x-ray conversion efficiency per Xe mole fraction was found to have maximum values at the Xe fractions of 10% for IL=6.0×1011 W/cm2 and 5% for IL=1.2×1012 W/cm2, which were about five and ten times as large as that in a pure Xe target, respectively. The x-ray conversion efficiencies in the cryogenic mixture targets at Xe fractions of 10%–40% were about 1.3 %/sr/nm for λ=10.8 nm and IL=1012 W/cm2, which was as high as that in a pure Xe cryogenic target. The physical mechanism behind this enhanced emission is discussed.

Investigation of the Incidence rate of Deep Vein Thrombosis in Patients Undergoing Laparoscopic Cholecystectomy with and without Prophylaxis

Article type: Original article Background and Aim: It has been suggested that thromboembolism occurs more frequently after laparoscopic cholecystectomy. This study aimed to evaluate the incidence of Deep Vein Thrombosis (DVT) in patients undergoing laparoscopic cholecystectomy with and without prophylaxis in hospitals affiliated to Azad University from 2011 to 2014. Materials and Methods: This retrospective cohort study was performed on 150 patients in two groups of 75 who underwent laparoscopic cholecystectomy in hospitals affiliated to Azad University from 2011 to 2014. A pre-made checklist was used to record patient's information such as age, gender, body mass index, treatment complications, and DVT. Furthermore, the patients were evaluated based on Wells score; moreover, a quantitative D-dimer test, and three risk classifications (Wells score) for DVT were performed 72 h and 14 days after surgery. Patients with a high preoperative probability score and a positive preoperative D-dimer were excluded from the study. All images with a high probability postoperative score for DVT and/or positive postoperative D-dimers were scanned for definitive diagnosis of DVT. Finally, the data were analyzed in SPSS software (version 22) through the Chi-square test. A p-value less than 0.05 was considered statistically significant. Results: The DVT was not observed in any of the patients in the two groups. Moreover, 40% and 20% of the patients in the case and control groups had coronary artery disease, respectively, which was statistically a significant difference (P=0.008). Furthermore, 48% and 20% of the cases in the case and control groups had hypertension, respectively, which was statistically significant (P=0.0001). In addition, 28% and 6.7% of the patients in the case and control groups had hyperlipoproteinemia, respectively, which showed a significant difference between the two groups in this regard (P=0.001). In total, 20% and 6.7% of the individuals in the case and control groups were sedentary, respectively, which showed a statistically significant difference (P=0.016). Conclusion: In this study, even those who were supposed to receive DVT according to the instructions did not receive it and did not develop DVT; therefore, it is not necessary to prescribe prophylaxis for DVT.

Vapour—liquid equilibrium of H2S‐Hydrocarbon mixtures using a generalized cubic equation of state

A generalized cubic equation of state proposed by one of the authors has been applied to the calculation of vapour-liquid equilibrium (VLE) of hydrogen sulfide-containing systems. Experimental VLE data for hydrogen sulfide + hydrocarbons, taken from the literature, have been systematically studied using the generalized equation and conventional van der Waals's mixing rules. The interaction parameter required in the mixing rules was obtained for thirteen systems at different temperatures, and a correlation for the interaction parameter as a function of the reduced temperature of the hydrocarbon solvent is proposed. The correlation for the interaction parameter is recommended for predicting VLE in processes in which hydrogen sulfide mixtures are involved. Une equation d'etat cubique generalisee proposee par l'un des auteurs a ete appliquee au calcul de l'equilibre liquide-vapeur(ELV) pour differents systemes contenant du sulfure d'hydrogene. A l'aide de cette equation generalisee et des regles de melange de van der Waals habituelles, on a etudie de maniere systematique des donnees d'ELV experimentales de systemes hydrocarbures + sulfure d'hydrogene recueillies dans la litterature scientifique. Le parametre d'interation requis dans les regles de melange a ete obtenu pour treize systemes a des temperatures differentes, et on propose une correlation pour le parametre d'interaction qui fait intervenir la temperature reduite du solvant de l'hydrocarbure. La correlation pour le parametre d'interaction est recommandee pour la prediction de l'ELV dans des procedes impliquant des melanges ou le sulfure d'hydrogene est present.
