Combining ability analysis and heterosis estimates in high quality protein maize inbred lines

Combining ability analysis using top cross method was performed in high quality protein maize (QPM) inbred lines for yield and yield contributing characters in order to assess the QPM inbred lines for general combining ability (gca) and to estimate mid parent and standard heterosis. The major interest was to seek out specific set of lines having maximum genetic distance that maximizes expression of heterosis in hybrid combination. The top cross, I14 x S superceded the checks in grain yield followed by the other crosses I6 x S, I4 x S, I3 x S, I18 x S and I7 x S. Significant positive gca effects for grain yield were revealed by the inbred I3, I4 and I6. Mid parent heterosis was observed to be 53.08% for grain yield in cross, I14 x S. The cross showed highest standard heterosis for grain yield (36.83%). The inbred line I7, I18 and I20 revealed negative significant gca effects for days to 50% silking which can be utilized for developing early maturing hybrids.
Comparative Venture Capital Governance. Private Versus Labour Sponsored Venture Capital Funds

Private independent limited partnership venture capital funds receive capital from institutional investors, without tax incentives. Limited partnership investment activities are governed by restrictive covenants that are determined by negotiated contract between the fund managers (general partners) and the institutional investors (limited partners). By contrast, Canadian Labour Sponsored Venture Capital Corporations (LSVCCs) receive capital only from individual investors who receive tax breaks on capital contributions of up to CAN$5,000. LSVCC investment activities are governed by statutory restrictions. This chapter contrasts the governance of LSVCCs to limited partnerships. We also summarize Canadian evidence on the impact of LSVCC governance and tax incentives: (1) on the distribution of venture capital funding between private and LSVCC funds; (2) on the unusually large overhang of uninvested capital in the Canadian venture capital industry; (3) the portfolio size (i.e. number of investee firms per fund) of private funds versus LSVCCs; and (4) the performance of LSVCCs relative to other types of venture capital organiziations and other comparable investments for individual investors.
Overview of undesirable effects of using diatomaceous earths for direct mixing with grains

Despite numerous advantages of diatomaceous earth (DE), its use for direct mixing with grains to control stored-product insects remains limited because of some very serious obstacles and disadvantages. The main obstacles preventing a wider use of DEs for mixing with grain, such as health concerns, the reduction in bulk density, differences in insect species tolerance to the same DE formulation, the effects of grain moisture and temperature on the effectiveness against insects, the influence of various commodities on DE efficacy, the use of DEs in some other fields, and possible solutions for overcoming DE limitations during direct mixing with grains are described in this manuscript. The same attempts have been made to discover new ways of increasing significantly the effectiveness against insects when much lower concentrations are used for direct mixing with grains. If these newer enhanced formulations can respond to the existing limitations of diatomaceous earth, a wider utilization of diatomaceous earth may be expected to control stored-product insect pests.

Background/Aim. It is estimated that worldwide circulates about 230 million refugees and asylum seekers. Parasitosis are diagnosed in recent years with increasing frequency both in Europe and in other developed countries. International migration of population, as an inalienable part and a result of the process of globalization, has an increasing impact on the health of the population of countries through which migrants pass and where they settle. The aim of this study was to determine the incidence of intestinal parasitic diseases in asylum seekers on the territory of Belgrade. Methods. The study group included 97 asylum seekers from the Centre for asylum seekers in Obrenovac, throughout year 2013 and 2014. Stool samples were taken less than seven days after arriving in the Center, and sent in Laboratory for parasitological diagnosis in Public Health Institute of Belgrade. Detection of parasites in stool samples was performed by a direct native slide made of fresh sample, and direct slide made after stool concentration "Mini Parasep" technique. Statistical analysis included application of Chi-squared test of matching and Chi-squared test of independence. Results. The study has shown that the parasites were detected in 9.3% of cases, in the age group 15-24 years. Protozoa were found in 6.2% and helminthes in 3.1% samples. Conclusion. In conclusion, most intestinal parasitosis were found in asylum seekers from Bangladesh. All parasitosis were found in males and the most frequently detected parasite was Giardia lamblia.
of Chemical Engineering SUPERCRITICAL EXTRACTION OF CARQUEJA ESSENTIAL OIL : EXPERIMENTS AND MODELING

Baccharis trimera is a native Brazilian plant which has medicinal properties. In this work a method of supercritical extraction was studied to obtain the popularly essential oil from Baccharis trimera, known as carqueja. The aim was to obtain experimental data and to compare two mathematical models used in the simulation of carqueja (Baccharis trimera) oil extraction by supercritical CO2. The two mathematical models are based on mass transfer. One of the models, proposed by Reverchon, is solved numerically and requires two adjustable parameters from the experimental data. The other model chosen is the one proposed by Sovová. This model is solved analytically and requires four adjustable parameters. Numerical results are presented and discussed for the adjusted parameters. The experimental results are obtained in a temperature range of 313.15 K to 343.15 K at 90 bar. The extraction yield of carqueja essential oil using supercritical carbon dioxide ranged between 1.72 % (w/w) at 323.15 K and 2.34 % (w/w) at 343.15 K, 90 bar with a CO2 flow rate of 3.34. 10 m/s for a 0.0015 kg sample of Baccharis trimera.
A Novel Dual Inductor DC-DC Buck Converter

A novel DC-DC Buck Converter using dual inductor and switched capacitor is proposed. Proposed circuit consists of two inductor instead of single inductor used in conventional dc-dc buck converter. The proposed converter offers better efficiency in obtaining same low voltage gain. Energy is effectively transferred from source to load using one inductor and capacitor while other inductor is used to step down the voltage and also get better efficiency than conventional dc-dc buck converter. In switch on time period the two inductors are in parallel and in off time period the two inductors are in series, on that time two inductors charged the output capacitor to get better efficiency. Simulation results verified the high efficiency three-stage operation of the proposed converter.
THE COMPARISION OF PROBABILISTIC SEISMIC DEMAND MODELS ESTIMATED THROUGH THE INCREMANTAL DYNAMIC ANALYSIS AND THE USE OF SCALED GROUND MOTION RECORDS

A reliable estimation of seismic demand is an essential part of recently developed performance based design engineering. In this estimation a Probabilistic Seismic Demand Model (PSDM) must be implemented to predict the mean value of the demand at the specific value of intensity measure parameter. In this paper it is tried to perform a comparison between the PSDMs which are obtained through the results of nonlinear dynamic analysis subjected to a set of scaled records with the models determined through the results of incremental dynamic analysis in order to find the proper value for the scale factor. The results show that model estimation using only a single scale factor is achievable in the case of 3 and 6-storey frames and for 9, 12 and 15-storey frames, the combination of scaled and un-scaled records can lead to reliable estimation of parameters.
Effects on density, shrinking, color changing and chemical surface analysis through FTIR of Tectona grandis thermo-treated

Thermal-treatment wood is used as an option to improve durability of wood in recent years. This study evaluated the effect of temperature in thermally treated Tectona grandis wood in density, shrinking, color changing (L*a*b* system) and surface analysis through FTIR. Sapwood and heartwood boards sawn with radial and tangential patterns were exposed to three temperature-levels: 210 oC, 215 oC, 220 °C during 6 hours and thermally treated wood properties were compared with untreated wood. Results showed that density decreased from 0.61 to 0.49 g cm-3 with a tendency to decrease as temperature increases. Wood shrinking ranges from 2.61 to 1.58 % and no statistical differences between temperatures were found. The FTIR analysis showed a slight increase in the bands at 1024 cm-1, 1098 cm-1, 1131 cm-1, 1249 cm-1 2928 cm-1 and 3340 cm-1 with the temperature increases, indicating a lignin change. Color change showed major changes in luminosity (L*), followed by redness (a*); while yellowness (b*) showed minor changes. Finally, the thermal treatment at 220 °C had the best results regarding the evaluated properties.
History and destiny of an emerging early-type galaxy

Context. The merging of galaxies is one key aspect in our favourite hierarchical ΛCDM Universe and is an important channel leading to massive quiescent elliptical galaxies. Understanding this complex transformational process is ongoing. Aims. We aim to study NGC 7252, which is one of the nearest major-merger galaxy remnants, observed ~1 Gyr after the collision of presumably two gas-rich disc galaxies. It is therefore an ideal laboratory to study the processes inherent to the transformation of disc galaxies to ellipticals. Methods. We obtained wide-field IFU spectroscopy with the VLT-VIMOS integral-field spectrograph covering the central 50′′ × 50′′ of NGC 7252 to map the stellar and ionised gas kinematics, and the distribution and conditions of the ionised gas, revealing the extent of ongoing star formation and recent star formation history. Results. Contrary to previous studies, we find the inner gas disc not to be counter-rotating with respect to the stars. In addition, the stellar kinematics appear complex with a clear indication of a prolate-like rotation component which suggests a polar merger configuration. The ongoing star formation rate is 2.2 ± 0.6 M⊙ yr−1 and implies a typical depletion time of ~2 Gyr given the molecular gas content. Furthermore, the spatially resolved star formation history suggests a slight radial dependence, moving outwards at later times. We confirm a large AGN-ionised gas cloud previously discovered ~5 kpc south of the nucleus, and find a higher ionisation state of the ionised gas at the galaxy centre relative to the surrounding gas disc. Although the higher ionisation towards the centre is potentially degenerate within the central star forming ring, it may be associated with a low-luminosity AGN. Conclusions. Although NGC 7252 has been classified as post-starburst galaxy at the centre, the elliptical-like major-merger remnant still appears very active. A central kpc-scale gas disc has presumably re-formed quickly within the last 100 Myr after final coalescence. The disc features ongoing star formation, implying Gyr long timescale to reach the red sequence through gas consumption alone. While NGC 7252 is useful to probe the transformation from discs to ellipticals, it is not well-suited to study the transformation from blue to red at this point.
Towards Food Security and Youth Participation in Community Development in Cross River and Akwa Ibom States: Implications for Counselling

The study was designed to investigate food security and youth participation in community development in Cross River and Akwa Ibom States. The ex-post factor research design was employed in this study. Four research hypotheses were formulated to guide the researchers in this study. The population for the study was five thousand (5,000) youths from Cross River and Akwa Ibom States. The sample was 506 youths made up of 307 boys and 199 girls using stratified random sampling and simple random sampling techniques. The major instrument for data collection was a four point likert type scale called Food Security and Youth Participation in Community Development (FSYPCD). Pearson Product Moment Correlational statistics, independent t-test and simple percentage were used to analyze the data. Findings indicated that there is a relationship between youths‟ participation in community development and food security. That there is no significant difference between Akwa Ibom and Cross River States in-terms of government‟s motivation of youths to ensure food security, food production and that there is a relationship between youths‟ participation in community development and political education. Counselling implications were raised to ensure food security in the two States, Cross River and Akwa Ibom and the nation at large such as reversing rural-urban migration to urban-rural migration, providing more social amenities in the rural areas, giving interest free loans and giving the youths adequate political education to enliven their participation in food security, food production and community development. Key words : Food Security, Food Production, Youth Participation, community development, Political Education, Government‘s Motivation of Youths.

Precise Orbit Determination of GRACE-A Satellite with Kinematic GPS PPP

ABSTRACT Precise Point Positioning (PPP) has been widely used in navigation and orbit determination applications as we can obtain precise Global Positioning System (GPS) satellite orbit and clock products. Kinematic PPP, which is based on the GPS measurements only from the spaceborne GPS receiver, has some advantages for a simple precise orbit determination (POD). In this study, we developed kinematic PPP technique to estimate the orbits of GRACE-A satellite. The comparison of the mean position between the JPL’s orbit product and our results showed the orbit differences 0.18 cm, 0.54 cm, and 0.98 cm in the Radial, in Along-track, and Cross-track direction respectively. In addition, we obtained the root mean square (rms) values of 4.06 cm, 3.90 cm, and 3.23 cm in the satellite coordinate components relative to the known coordinates. Keywords: GRACE-A, kinematic, PPP, POD channels are used for the measurement of the precise orbit, while the remaining four are used for the measurement of the occultation for the GPS satellite. The GPS measurements of GRACE satellites are obtained with 10-second intervals.The orbit estimation of the low earth orbit (LEO) satellite largely is classified into kinematic, dynamic, and reduced-dynamic methods. They can be applied in the orbit determination based on different types of observation data and data-processing strategies. The ‘dynamic’ method is the most general method of the orbit determination. All factors of the physical acceleration which affects the satellite and every related model parameters should be considered. Since the ‘kinematic’ method requires only the GPS measurements without using the orbital equation, it can be applied to the orbit determination in a simple way (Montenbruck 2003). However, this could reveal different performances for the orbit of the satellite based on the level of accuracy given by the measurement model and the quality of the observation data. The ‘reduced-dynamic’ method applies the geometrical correction to the orbit of the satellite, which is obtained by using the typical ‘dynamic’ method, by using the GPS measurement. The well-known GIPSY/OASIS II developed by Jet Propulsion Laboratory (JPL) of the US can be regarded as the most representative
Neutralized solar wind ahead of the Earth's magnetopause as contribution to non-thermal exospheric hydrogen

Abstract. In a most recent paper by Qin and Waldrop (2016), it had been found that the scale height of hydrogen in the upper exosphere of the Earth, especially during solar minimum conditions, appears to be surprisingly large. This indicates that during minimum conditions when exobasic temperatures should be small, large exospheric H-scale heights predominate. They thus seem to indicate the presence of a non-thermal hydrogen component in the upper exosphere. In the following parts of the paper we shall investigate what fraction of such expected hot hydrogen atoms could have their origin from protons of the shocked solar wind ahead of the magnetopause converted into energetic neutral atoms (ENAs) via charge-exchange processes with normal atmospheric, i.e., exospheric hydrogen atoms that in the first step evaporate from the exobase into the magnetosheath plasma region. We shall show that, dependent on the sunward location of the magnetopause, the density of these types of non-thermal hydrogen atoms (H-ENAs) becomes progressively comparable with the density of exobasic hydrogen with increasing altitude. At low exobasic heights, however, their contribution is negligible. At the end of this paper, we finally study the question of whether the H-ENA population could even be understood as a self-consistency phenomenon of the H-ENA population, especially during solar activity minimum conditions, i.e., H-ENAs leaving the exosphere being replaced by H-ENAs injected into the exosphere. Keywords. Magnetospheric physics (plasmasphere; solar wind-magnetosphere interactions) – solar physics, astrophysics, and astronomy (energetic particles)
Calibration of temperature in the lower stratosphere from microwave measurements using COSMIC radio occultation data: Preliminary results

Accurate, consistent, and stable observations from different satellite missions are crucial for climate change detection. In this study, we use Global Positioning System (GPS) Radio Occultation (RO) data from the early phase of the FORMOSAT-3/Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) mission, which was successfully launched on 15 April 2006, to inter-calibrate Temperature in the Lower Stratosphere (TLS) taken from Advanced Microwave Sounding Unit (AMSU) microwave measurements from different satellites for potential improvements of stratospheric temperature trend analysis. With a limited number of COSMIC soundings in the early phase of the mission, these results are considered preliminary. In this study, we use COSMIC RO data to simulate microwave brightness temperatures, for comparison with AMSU Ch9 measurements (e.g., TLS) on board NOAA15, 16 and 18. Excellent correlation was found between synthetic COSMIC brightness temperatures (Tbs) and Tbs from NOAA15, NOAA16 and NOAA18, respectively. However, systematic differences on the order of 0.7 K to 2 K were found between COSMIC and AMSU observations over Antarctica. Our results demonstrate that synthetic COSMIC Tbs are very useful in identifying inter-satellite offsets among AMSU measurements from different satellites. To demonstrate the long-term stability of GPS RO data, we compare COSMIC dry temperature profiles to those from collocated CHAMP profiles, where CHAMP was launched in 2001. The fact that the CHAMP and COSMIC dry temperature difference between 500 hPa and 10 hPa ranges from -0.35 K (at 10 hPa) to 0.25 K (at 30 hPa) and their mean difference is about -0.034 K demonstrates the long-term stability of GPS RO signals. In order to demonstrate the potential usage of the GPS RO calibrated AMSU Tbs to inter-calibrate other overlapping AMSU Tbs, we examine the uncertainty of the calibration coefficients derived from AMSU-GPS RO pairs. We found the difference between COSMIC calibrated AMSU Tbs and those from CHAMP to be in the range of ±0.07 K with 0.1 K standard deviation. This demonstrates the robustness of the calibration
The Membership Life Cycle in Online Support Groups

This study explores the membership life cycle in online support groups for people with depression by examining 558 people with various membership durations in 16 online support groups. Results indicated that membership duration was associated with age, self-defined condition, frequency of visits, active posting, the benefits gained from participation, and the level of depression. Related to both behavioral and psychological aspects of participation, these findings serve as a basis for suggesting a membership life cycle model that is exclusive for online support groups.
Effects of emotional picture on movement trajectory: The role of meaning and the power of context

Aim of the study: The present study tests the effect of the attention to emotional content on movement trajectory. Methods: Pictures with positive and negative valence were presented on both sides of a simulated road in a driving-simulation tracking task for a series of two experiments for a total of 28 participants. Results: Both the approach and withdrawal effects toward/from the position in which emotional cues appeared have been found on the participants’ trajectory. In contrast to previous literature and common-sense hypotheses, these effects depended on the picture-presentation setting more than on their emotional valence. Some predictions in the literature pointed to finding approach movements for positive pictures and withdrawal behaviours for negative valences. In this sense, only negative pictures presented in close positions on the left-side of the road have been found to provoke approach tendencies. Conclusions: The “emotional”, right hemisphere processed picture presentations on the left side. Since it is impossible to select negative emotional pictures that do not have high emotional arousal, results point out to pictures arousal as the cause of the effects found. These findings are discussed under the perspectives of hemisphere laterality and models of motor control. The present study supports the MDRA model in its premise about how context can modify the meanings of attentional cues and, in turn, their impact on movement programming.
