A simulation study with a new residual ionospheric error model for GPS radio occultation climatologies

Abstract. In this study, a new model was explored which corrects for higher order ionospheric residuals in Global Positioning System (GPS) radio occultation (RO) data. Recently, the theoretical basis of this new "residual ionospheric error model" has been outlined (Healy and Culverwell, 2015). The method was tested in simulations with a one-dimensional model ionosphere. The proposed new model for computing the residual ionospheric error is the product of two factors, one of which expresses its variation from profile to profile and from time to time in terms of measurable quantities (the L1 and L2 bending angles), while the other describes the weak variation with altitude. A simple integral expression for the residual error (Vorob’ev and Krasil’nikova, 1994) has been shown to be in excellent numerical agreement with the exact value, for a simple Chapman layer ionosphere. In this case, the "altitudinal" element of the residual error varies (decreases) by no more than about 25 % between ~10 and ~100 km for physically reasonable Chapman layer parameters. For other simple model ionospheres the integral can be evaluated exactly, and results are in reasonable agreement with those of an equivalent Chapman layer. In this follow-up study the overall objective was to explore the validity of the new residual ionospheric error model for more detailed simulations, based on modeling through a complex three-dimensional ionosphere. The simulation study was set up, simulating day and night GPS RO profiles for the period of a solar cycle with and without an ionosphere. The residual ionospheric error was studied, the new error model was tested, and temporal and spatial variations of the model were investigated. The model performed well in the simulation study, capturing the temporal variability of the ionospheric residual. Although it was not possible, due to high noise of the simulated bending-angle profiles at mid- to high latitudes, to perform a thorough latitudinal investigation of the performance of the model, first positive and encouraging results were found at low latitudes. Furthermore, first application tests of the model on the data showed a reduction in temperature level of the ionospheric residual at 40 km from about −2.2 to −0.2 K.
Mathematical Modeling and Experimental Validation of Mixed Metal Oxide Thin Film Deposition by Spray Pyrolysis

The deposition of metal oxide films using Spray Pyrolysis Technique (SPT) is investigated through mathematical and physical modeling. A comprehensive model is developed in the processes including atomization, spray, evaporation, chemical reaction and deposition. The predicted results including particle size and film thickness are compared with the experimental data obtained in a complementary study. The predicted film thickness is in a good agreement with the measurements when the temperature is high enough for the chemical reaction to proceed. The model also adequately predicts the size distribution when the nanocrystals are well-structured at controlled temperature and concentration.
Influence of dietary conjugated linoleic acid isomers and selenium on growth, feed efficiency, and liver fatty acid profile in rats

The influence of dietary CLA isomer(s) and/or selenized yeast on the growth, concentration of CLA isomers and other fatty acids in the liver was investigated in rats. Plasma blood triacylglycerols (TAG), total cholesterol (TC), HDL and LDL cholesterol fractions in relation to dietary CLA isomer(s) and/or selenium (Se) were analysed. The experiment was performed on female rats (Wistar), 8 weeks of age and initial body weight of about 200 g. After a 1-week preliminary period, for 4 weeks the animals were fed a diet enriched in conjugated linoleic acid (CLA) isomer(s) and selenized yeast (2×2 experimental design). Dietary Se or/and CLA isomer(s) resulted in small changes in the spleen, heart, kidneys and brain, and increased liver weight. Administration of Se and trans10cis12CLA most efficiently increased the body weight gain of rats. CLA isomer(s) administered with or without Se elevated the CLA isomer(s) level in the liver. These results demonstrate that trans,transCLA isomers are metabolized more slowly, while cis,trans/trans,cisCLA isomers, more rapidly to longchain fatty acids containing a conjugated double bond. Enrichment of the diet in CLA isomer(s) with or without Se caused a reduction in the capacity of Δ9-, Δ6and Δ5-desaturases in the liver, while dietary trans10cis12CLA or the CLA isomer mixture increased Δ4-desaturases. The contents of oleic acid, C20:4n-6, and C20:5n-3 decreased in the liver, whereas the level of C22:5n-3 and C22:6n-3 increased in the liver of rats fed the CLA isomer mixture. Individual dietary CLA isomers with or without Se increased the concentration of palmitic and stearic acids in the liver. All experimental diets increased the concentration of triacylglycerols in blood plasma, while trans10cis12CLA with or without Se usually decreased the concentration of total cholesterol, LDL, and HDL cholesterol.
Clinical and neuropsychological predictors of the diagnosis of dementia with Lewy bodies

Introduction: The pattern of clinical symptoms and cognitive impairment in dementia with Lewy bodies (DLB) is different from Alzheimer’s disease (AD). The aim of this study was to determine which clinical or neuropsychological features most accurately predicted the diagnosis of DLB or AD in the early stage of dementia. Material and methods: Sixty-two subjects were included, 20 of those with clinically diagnosed DLB, 23 with AD and 19 cognitively intact controls. An elaborated battery of clinical and neuropsychological tools was applied. Results: There were significant differences in clinical variables between the dementia groups despite similar duration of disease. In comparison to AD patients, the subjects with probable DLB achieved significantly worse scores in the NPI, HIS, UPDRS and ADL scales. The presence/recent history of apathy and visual hallucinations were significantly more frequent in DLB. The onset of neuropsychiatric symptoms was earlier in DLB and the symptoms were more severe in this group. The DLB cases had an increased prevalence of a positive history of REM sleep behaviour disorder and anosmia as well. The DLB group was more impaired in category fluency (animals), visuoperceptual, constructional, and attention tasks. Conclusions: DLB patients have a different profile of clinical symptoms and neuropsychological deficits early in the course of dementia compared to the AD group. Neuropsychological evaluation in AD and DLB reveals multiple cognitive deficits even in early and moderate dementia.
Corporate entrepreneurship in the public sector: a South African perspective

Over the last three decades, organisations worldwide have used corporate entrepreneurship (CE) as a means of building new competencies, revitalizing operations, achieving renewal, and creating value for stakeholders. However, little is understood about factors triggering CE within the public sector. The aim of this paper was to collect relevant principles and concepts from existing entrepreneurship and CE literature, which could then be refined, developed and used in the public sector to foster a new entrepreneurial-orientated climate. This paper determines the entrepreneurial orientation (EO) amongst managers and what antecedents promote entrepreneurship in the public sector. It used data from managers within organisations under the Minister of Public Service and Administration (MPSA). The findings of this study can therefore be used to develop strategies that can be applied within the public sector as a whole to improve organisational performance. This paper concludes with a discussion on implications for both theory and practise.
Influence of indoor air temperature variation on office work performance

Abstract Indoor air quality as well as thermal comfort has a significant effect on productivity of the employees in office buildings. It may reduce work performance and cause financial losses in a long term perspective. Sudden temperature swings may have an impact on the work performance as well. The aim of this study was to assess the change of office work performance of the same individuals affected by unsteady air temperature. Office work was simulated in the test chamber with two workplaces and two persons at the time. 78 individuals of age 19 to 31 were divided into three groups and took participation in performing productivity tests. Two cases were analysed: one with the temperature rise from +22 to +26 °C and another with the temperature drop from +22 to +18 °C. The same tests were performed with the placebo group under a constant air temperature of +22 °C. Results of the study showed that subjects in the placebo group performed better while executing tasks for the second time and the overall produ.

Topography and spatial variability of soil physical properties

Among the soil formation factors, relief is one of the most used in soil mapping, because of its strong correlation with the spatial variability of soil attributes over a landscape. In this study the relationship between topography and the spatial variability of some soil physical properties was evaluated. The study site, a pasture with 2.84 ha, is located near Seropedica, Rio de Janeiro State, Brazil, where a regular square grid with 20 m spacing was laid out and georreferenced. In each sampling point, altitude was measured and undisturbed soil samples were collected, at 0.0-0.1, 0.1-0.2, and 0.2-0.3 m depths. Organic carbon content, soil texture, bulk density, particle density, and soil water retention at 10 (Field Capacity), 80 (limit of tensiometer reading) and 1500 kPa (Permanent Wilting Point) were determined. Descriptive statistics was used to evaluate central tendency and dispersion parameters of the data. Semivariograms and cross semivariograms were calculated to evaluate the spatial variability of elevation and soil physical attributes, as well as, the relation between elevation and soil physical attributes. Except for silt fraction content (at the three depths), bulk density (at 0.2-0.3 m) and particle density (at 0.0-0.1 m depth), all soil attributes showed a strong spatial dependence. Areas with higher elevation presented higher values of clay content, as well as soil water retention at 10, 80 and 1500 kPa. The correlation between altitude and soil physical attributes decreased as soil depth increased. The cross semivariograms demonstrated the viability in using altitude as an auxiliary variable to improve the interpolation of sand and clay contents at the depth of 0.0-0.3 m, and of water retention at 10, 80 and 1500 kPa at the depth of 0.0-0.2 m.
Personality Structure in the Trait Lexicon of Hindi, a Major Language Spoken in India

The psycho–lexical approach is extended to Hindi, a major language spoken in India. From both the dictionary and from Hindi novels, a huge set of personality descriptors was put together, ultimately reduced to a manageable set of 295 trait terms. Both self and peer ratings were collected on those terms from a sample of 511 participants. Factor analyses (principal components analysis), performed separately on self and on peer ratings, suggested three up to six factors. From a comparison with an ancient but still popular system of personality description, called the triguna, and from a comparison with a recently developed comprehensive trait taxonomy in Dutch, it was concluded that only three factors, not to be confused with the Big Three, firmly stood out, all three belonging to the three–dimensional triguna. Congruence coefficients between factors based on self and on peer ratings confirmed the stability of these three factors. The three factors are called rajasic, representing ambition, friendliness, humility versus hypocrisy, deception and violence, tamasic, representing egoism, mean mindedness and concealment, and finally sattvic, representing competence, impartiality, being organized, sober and harmonious.

Polyamines and WOX genes in the recalcitrance to plant conversion of somatic embryos of Habanero pepper (Capsicum chinense Jacq.)

In order to determine the role of polyamines in the formation and development of the somatic embryos of Capsicum chinense, the effect of different concentrations (0, 0.01, 0.1, and 1.0 mM) of Putrescine, Spermidine and Spermine on the efficiency and morphology of the embryos was evaluated. The results show that none of the three polyamines evaluated had a significant effect on the number of embryos formed, except Spermidine (1 mM), which caused a significant reduction in their numbers, in comparison with the control treatment. However, the most noteworthy result was observed in the treatment containing 0.1 mM of Spermine. The embryos developed in this treatment showed harmonic apex-radicle development, pale-green coloration and the formation of two tiny cotyledonary leaves. Real-time PCR was used to analyze the differential expression of the WUS, WOX1 and WOX3 genes in somatic embryos treated with Spermine and untreated, including the zygotic embryo. The transcript levels of the genes analyzed were found to differ significantly between both types of embryos (somatic and zygotic), with the zygotic embryos presenting a higher level of transcripts; however, compared to the untreated somatic embryos, the somatic embryos treated with Spermine showed an increase in the transcript levels of the three genes analyzed (WUS, WOX1 and WOX3); the WOX1 gene in particular presented an accumulation pattern similar to that of the zygotic embryo of the species. Key words: Somatic embryos, zygotic embryos, polyamines, transcript patterns and morphology.
SDSS-IV MaNGA: Probing the Kinematic Morphology–Density Relation of Early-type Galaxies with MaNGA

The “kinematic” morphology–density relation for early-type galaxies posits that those galaxies with low angular momentum are preferentially found in the highest-density regions of the universe. We use a large sample of galaxy groups with halo masses observed with the Mapping Nearby Galaxies at APO (MaNGA) survey to examine whether there is a correlation between local environment and rotational support that is independent of stellar mass. We find no compelling evidence for a relationship between the angular momentum content of early-type galaxies and either local overdensity or radial position within the group at fixed stellar mass.
Investigating the Relationship between Audit Quality and the Earning Response Coefficient of Listed Firms in Tehran Stock Exchange

In this study, the relationship between audit quality and earning response coefficient of listed firms in Tehran stock exchange organization is investigated. In particular, the aim of present study is to investigate the relationship between variables such as audit firm size, auditor industry specialization, audit committee tenure, and earning response coefficient (ERC). In order to answer the research questions, one primary hypothesis and four secondary hypotheses are developed and tested on 100 firms selected from the firms listed in Tehran stock exchange (T.S.E). The applied method is a descriptive correlation research method. For testing the hypotheses, a combination of regression models and panel data were used. The results of this study indicate a direct meaningful relationship between audit firm size, auditor industry specialization and the length of auditor tenure on ERC. However, no meaningful relationship was observed between the existence of an audit committee with ERC. In general, this study found that increasing audit quality in firms leads to increase of ERC. Keywords: Audit Quality, Abnormal Return, Unexpected Earning, Earning Response Coefficient.
Assessment of the genetic relationship of Turkish olives (Olea europaea subsp. europaea) cultivars based on cpDNA trnL-F regions

Abstract The olive tree (Olea europaea L.) is one of the major cultivated species in the world, and Mediterranean countries produce about 90% of world cultivated olives. In this study, the genetic relationship of seven Turkish olive cultivars was investigated using non-coding trnL-F regions in chloroplastic genome. Cultivars demonstrated a similar sequence length of 330-340 bp with an average 35.26% G+C content. Variable (polymorphic/segregating), parsimony informative and total numbers of the insertion or the deletion of bases in the DNA (indel sites) were 4, 3, and 28, respectively. Nucleotide diversities π and θ were found as 0.00631 and 0.00644 respectively, while Tajima’s D was −0.786. cpDNA trnL-F regions of sequenced Turkish olive cultivars had a low level of genetic variations, and these non-coding regions were strictly conserved in all analyzed cultivars. Geographically distant shared more sequence similarities than relatively close cultivars. The phylogenetic analyses indicated that the biogeographic distribution of cultivars does not demonstrate any association inferring cultivar source. These results indicate the possibility of germplasm exchanges among countries or that some indel mutations contribute to variations of the Turkish olive gene pool. Thus, the authorities should develop the necessary programs to preserve the purity of native germplasms.
A NOVEL ALIGNMENT PROCEDURE FOR THE FINAL FOCUS OF FUTURE LINEAR COLLIDERS

An algorithm for the simultaneous optimization of orbit, dispersion, coupling and beta-beating in the final focus of future linear colliders is presented. Based on orbit and dispersion measurements the algorithm determines the optimal corrector settings in order to simultaneously minimize the r.m. s orbit, the r.m. s dispersion, the r.m. s coupling, the r.m.s. beta-beating and the r.m. s strength of the dipoles correctors. A number of different options for error handling of beam position monitors, weighting, and correction have been introduced to ensure the stability of the algorithm. A sextupole tuning procedure is also applied to further optimize the beam parameters at the interaction point. Preliminary results for the beam delivery systems of CLIC are presented.
Analysis of Factors Affecting Stock Price Behaviour: A Study on Listed Companies in Bombay Stock Exchange

: Dividend is the portion of profit which is being taken from corporate profits of the company after retaining the amount for further investment (retained earnings). Dividend Policy is influenced by various factors i.e. external as well as internal. Dividend policy is associated with the profitability positioning of the company.

Cusp form motives and admissible G-covers

This thesis contains three articles related to operads and moduli spaces of admissible covers of curves. In Paper A we isolate cohomology classes coming from modular forms inside a certain space of admissible covers, thereby showing that this moduli space can be used as a substitute for a Kuga–Sato variety. Paper B contains a combinatorial proof of Ezra Getzler’s semiclassical approximation for modular operads, and a proof of a formula needed in Paper A. In Paper C we explain in what sense spaces of admissible covers form a modular operad, by introducing the notion of an operad colored by a groupoid.
Indigenous knowledge language systems as source of educational psychology principles for teaching and learning: A case of traditional African cultures of Zimbabwe

The study explores how the traditional African cultures of Zimbabwe have used their indigenous knowledge of tsumo (proverbs) for teaching their children cultural norms and values. The study argues that if educational psychology is about what goes on in teaching and learning, then the ways the traditional African elders have used proverbs (tsumo) to successfully teach children about ways of behaving, are based on educational psychology principles. The study adopted the qualitative field- based approach whereby the Karanga language speaking people of Masvingo province of Zimbabwe were interrogated on how the statements of proverbs (tsumo) entrenched in their language, are used to teach children ways of understanding the world. The study also used documentary evidence of selected statements of proverbs (tsumo) to illustrate the relationship between the potential effect of these proverbs (tsumo) on changing human behaviour and that of the principles of educational psychology. Results have indicated that the scientific methods that culminated in the pronouncement of the general statements of educational psychology theories and principles were and are still the same methods that elders of the indigenous African societies used and still use today to formulate general statements of truths called proverbs (tsumo). Key words: traditional African cultures; indigenous knowledge; proverbs (tsumo); educational psychology; scientific knowledge
