Abstract:
The effect of growing conditions on starch and protein content in triticale grain and amylose content in starch was studied on winter triticale cvs. Kitaro, Lupus, Lamberto and Ticino harvested in 2006 and 2007 in Humpolec and Pernolec, Czech Republic. Dry matter of the investigated triticale grain contained 62.4–70.9% of starch. The starch content and amylose content in starch were significantly affected by cultivar and year. Statistical analysis did not confirm that starch content and amylose content in starch were significantly influenced by growing variant or location. The protein content was significantly affected only by year. The differences in protein content among cultivars, growing variants and locations were not significant. The protein content was negatively correlated with starch content (<I>r</I> = –0.83). Statistical analysis of data also confirmed a positive correlation between the starch content and amylose content in starch (<I>r</I> = 0.45).

Abstract:
Small-plot field trials monitored the effect of drip irrigation of potatoes on tuber and starch yield. The trials were performed at two different localities in two trial years, 2016 and 2017. The subject of the evaluation included two cultivars with different vegetation periods (the very early cv. Monika and the semi-early cv. Jolana). Four repeated trials studied 4 irrigation treatments according to the available water capacity (AWC) of the soil, i.e. without irrigation, irrigation when soil humidity decreased below 60, 65 and below 70% AWC. All monitored parameters reflected a positive effect of irrigation in comparison to the non-irrigated control. The Žabčice locality showed the highest tuber and starch yields mostly after medium-intensity irrigation. The Valečov locality achieved the highest tuber and starch yields after the highest-intensity irrigation. Subject to the locality and the cultivar, the recommendation is to introduce automatic irrigation start when the soil humidity drops to 65% AWC for heavy soils and 70% AWC for medium heavy soils.

Abstract:
The physical properties of corn, wheat and rice starch edible films with different level of glycerol were evaluated. Starch films exhibited an apparent endothermic peak in the range of 151–199°C with corn starch film with 1.6% glycerol having a relatively lower T<sub>o</sub> and higher T<sub>p</sub>. X-ray diffraction spectroscopy indicated that the corn, wheat, rice starch powders had ~ 39–49% crystallinity, whereas Fourier transform infrared spectra showed peaks associated with the tightly bound water present in the rice, corn, wheat starches. Overall, glycerol addition could enhance the water vapour pressure barrier properties of the films, but their tensile strength was reduced. Corn starch films were identified as the most suitable choice for edible packaging as its thermal characteristics indicated suggested a more acceptable sealability. Rice starch films is proposed as the better choice for coating as it showed better flexibility as indicted by lower tensile and higher elongation properties.

Abstract:
In this study, the characteristic of cassava starch have been developed through esterification reaction using ethyl lactate. Commercial cassava starch was modified by using (0.5; 0.75; 1.00; 1.25; 1.50 % v/v) ethyl lactate solution with pH 6, 7, 8, 9 for 15, 25, 35, 45, 55 minutes and the drained starch was dried with sun drying. The cassava starch which has been esterified with 1.5% ethyl lactate for 15 minutes pH 6 gave highest volume expansion of 2,438.9 %. For swelling power, the highest value was 19.32 swelling power at variable concentrations of 1.5% ester, esterification period of 15 minutes, and pH 6. The lowest amylose content was 15.68 % in ester concentration of 1.5 %. From the scanning electron micrograph, shows that the cassava starch after and before modification has not changed since the modifications performed under the gelatinization temperature. FTIR spectra of native cassava starch and ester cassava starch shown shift of the carboxyl group of starch from 1072.37 to 1087.80 cm-1 and a decrease in the OH group is from 3452.53 to 3417.81 cm-1. Bond formed indicates that the esterification reaction occurs between cassava starch with ethyl lactate esters.

AbstractFirst we investigate the spectral and photometric properties (colours, magnitudes) of a sample of faint Be stars observed in the first exoplanet fields of CoRoT (IR1, LRA1 and LRC1). We determine the fundamental parameters by fitting ESO-FLAMES/GIRAFFE spectra with synthetic models taking account for non-LTE effects. After that we correct these parameters from fast rotation effects. We also study the location of each star in the (logL vs logT) HR diagram. Second we start to analyse the CoRoT light curves to investigate further the possible correlation between the pulsating properties and the fundamental parameters of the stars.

Abstract:
AbstractWe present a brief summary of the results of a study of the effects of dynamical evolution on the stellar mass function of multiple-population globular clusters. Theoretical studies have predicted that the process of multiple-population cluster formation results in a system in which second-generation (2G) stars are initially more centrally concentrated than first-generation (1G) stars. In the study presented here, we have explored the implications of the initial differences between the 2G and 1G structural properties for the evolution of the local (measured at different distances from a cluster center) and global mass function. We have studied both systems in which 1G and 2G stars start with the same initial mass function (IMF) and systems in which 1G and 2G stars have different IMFs. Finally we have explored the evolution of the spatial mixing and found that the multiscale nature of the clusters studied leads to a dependence of the mixing rate on the stellar mass.

The effects of hydrocolloids pectin, carrageenan, as well as of pectin/carrageenan mixtures on gelatinisation, retrogradation, rheological characteristics, and swelling power of tapioca starch were studied with Brookfield rotational viscometer and differential scanning calorimeter (DSC). The results showed that hydrocolloids retarded the retrogradation of tapioca starch. Enthalpy and temperatures of gelatinisation, as well as solubility, did not vary significantly in starch-hydrocolloid systems. Viscosity of tapioca starch increased on the addition of hydrocolloids: the effect of carrageenan on viscosity was more remarkable than that of pectin. &nbsp; &nbsp;

Full text
Abstract:
In industrialized economies such as the European countries unemployment rates are very responsive to the business cycle and significant shares stay unemployed for more than one year. To fight cyclical and long-term unemployment countries spend significant shares of their budget on Active Labor Market Policies (ALMP). To improve the allocation and design of ALMP it is essential for policy makers to have reliable evidence on the effectiveness of such programs available. Although the number of studies has been increased during the last decades, policy makers still lack evidence on innovative programs and for specific subgroups of the labor market. Using Germany as a case study, the dissertation aims at contributing in this way by providing new evidence on start-up subsidies, marginal employment and programs for youth unemployed. The idea behind start-up subsidies is to encourage unemployed individuals to exit unemployment by starting their own business. Those programs have compared to traditional programs of ALMP the advantage that not only the participant escapes unemployment but also might generate additional jobs for other individuals. Considering two distinct start-up subsidy programs, the dissertation adds three substantial aspects to the literature: First, the programs are effective in improving the employment and income situation of participants compared to non-participants in the long-run. Second, the analysis on effect heterogeneity reveals that the programs are particularly effective for disadvantaged groups in the labor market like low educated or low qualified individuals, and in regions with unfavorable economic conditions. Third, the analysis considers the effectiveness of start-up programs for women. Due to higher preferences for flexible working hours and limited part-time jobs, unemployed women often face more difficulties to integrate in dependent employment. It can be shown that start-up subsidy programs are very promising as unemployed women become self-employed which gives them more flexibility to reconcile work and family. Overall, the results suggest that the promotion of self-employment among the unemployed is a sensible strategy to fight unemployment by abolishing labor market barriers for disadvantaged groups and sustainably integrating those into the labor market. The next chapter of the dissertation considers the impact of marginal employment on labor market outcomes of the unemployed. Unemployed individuals in Germany are allowed to earn additional income during unemployment without suffering a reduction in their unemployment benefits. Those additional earnings are usually earned by taking up so-called marginal employment that is employment below a certain income level subject to reduced payroll taxes (also known as “mini-job”). The dissertation provides an empirical evaluation of the impact of marginal employment on unemployment duration and subsequent job quality. The results suggest that being marginal employed during unemployment has no significant effect on unemployment duration but extends employment duration. Moreover, it can be shown that taking up marginal employment is particularly effective for long-term unemployed, leading to higher job-finding probabilities and stronger job stability. It seems that mini-jobs can be an effective instrument to help long-term unemployed individuals to find (stable) jobs which is particularly interesting given the persistently high shares of long-term unemployed in European countries. Finally, the dissertation provides an empirical evaluation of the effectiveness of ALMP programs to improve labor market prospects of unemployed youth. Youth are generally considered a population at risk as they have lower search skills and little work experience compared to adults. This results in above-average turnover rates between jobs and unemployment for youth which is particularly sensitive to economic fluctuations. Therefore, countries spend significant resources on ALMP programs to fight youth unemployment. However, so far only little is known about the effectiveness of ALMP for unemployed youth and with respect to Germany no comprehensive quantitative analysis exists at all. Considering seven different ALMP programs, the results show an overall positive picture with respect to post-treatment employment probabilities for all measures under scrutiny except for job creation schemes. With respect to effect heterogeneity, it can be shown that almost all programs particularly improve the labor market prospects of youths with high levels of pretreatment schooling. Furthermore, youths who are assigned to the most successful employment measures have much better characteristics in terms of their pre-treatment employment chances compared to non-participants. Therefore, the program assignment process seems to favor individuals for whom the measures are most beneficial, indicating a lack of ALMP alternatives that could benefit low-educated youths.
Zur Verbesserung der Arbeitsmarktchancen arbeitsloser Personen und damit zur Bekämpfung von Arbeitslosigkeit werden innerhalb der Europäischen Union jedes Jahr beträchtliche Summen für Maßnahmen der aktiven Arbeitsmarktpolitik (AAP) aufgewendet. Vor diesem Hintergrund ergibt sich die Frage nach der Effektivität dieser Programme. Obwohl in den vergangenen Jahren zahlreiche empirische Evaluationsstudien durchgeführt und hierdurch wesentliche Erkenntnisse über die Wirksamkeit von AAP gewonnen wurden, bestehen noch stets unerforschte bzw. nur unzureichend erforschte Bereiche, wie zum Beispiel für innovative Programme oder für Untergruppen am Arbeitsmarkt. Hierin liegt der Beitrag der Dissertationsschrift. Am Beispiel von Deutschland werden neue Erkenntnisse zur Wirksamkeit der Existenzgründungsförderung, der geringfügigen Beschäftigung sowie der Programme für arbeitslose Jugendliche geliefert. Mit Einführung des Existenzgründungszuschusses (Ich-AG) im Rahmen der Hartz-Reformen, standen gründungswilligen Arbeitslosen, zusammen mit dem bereits seit Mitte der Achtziger Jahre bekannten Überbrückungsgeld, zwischen 2003 und 2006 zwei Förderprogramme zur Verfügung. Beide Programme umfassen eine monetäre Förderung während der Gründungsphase, um arbeitslosen Personen den Weg in die berufliche Selbständigkeit zu erleichtern. Die Analyse der beiden Programme zeigt deutlich, dass die intendierten Ziele, d.h. die Verbesserung der Beschäftigungschancen sowie der Einkommenssituation der Teilnehmer, erreicht wurden. Es zeigt sich weiter, dass beide Programme insbesondere effektiv für benachteiligte Gruppen am Arbeitsmarkt, wie z.B. Geringqualifizierte, sowie in Regionen mit eher schlechten ökonomischen Bedingungen sind. Aber auch die getrennte Analyse für Frauen zieht eine positive Bilanz. Hier erweist sich die Förderung als besonders wirksam, da die berufliche Selbständigkeit (im Gegensatz zur abh. Beschäftigung) anscheinend eine bessere Vereinbarkeit von Familie und Beruf ermöglicht. Abschließend lässt sich somit feststellen, dass die Förderung der beruflichen Selbständigkeit eine sinnvolle Strategie darstellt, da insbesondere bestehende Hürden für benachteiligte Gruppen am Arbeitsmarkt beseitigt und diese Personen langfristig in den Arbeitsmarkt integriert werden. Im nächsten Abschnitt der Dissertationsschrift wird die Aufnahme einer geringfügigen Beschäftigung während der Arbeitslosigkeit untersucht. In Deutschland können arbeitslose Personen bis zu 15 Stunden/Woche eine Beschäftigung aufnehmen, wobei ein Zuverdienst bis 165 Euro/Monat keine Auswirkung auf den Bezug von Arbeitslosengeld hat. Hierzu greifen arbeitslose Personen insbesondere auf die geringfügige Beschäftigung (genannt „Mini-Job“) zurück, da diese für die Arbeitslosen selbst abgabenfrei ist und Arbeitgeber nur einen reduzierten Beitrag zur Sozialversicherung sowie Einkommensteuer zahlen. Das erhöhte Einkommensniveau während der Arbeitslosigkeit sowie der enge Kontakt zum Arbeitsmarkt können unterschiedliche Wirkungen generieren. Es zeigt sich, dass die Aufnahme einer geringfügigen Beschäftigung grundsätzlich keinen signifikanten Einfluss auf die Arbeitslosigkeitsdauer hat, jedoch im Anschluss an die Arbeitslosigkeit zu längeren Beschäftigungsphasen führt. Die Untersuchung der Effektheterogenität zeigt, dass die geringfügige Beschäftigung während der Arbeitslosigkeit die Arbeitslosigkeitsdauer für Langzeitarbeitslose verkürzt und zu insgesamt stabileren Beschäftigungsphasen für diese Personengruppe führt. Das Ergebnis ist von hoher politischer Relevanz, da die Möglichkeit einer Zusatzbeschäftigung während der Arbeitslosigkeit anscheinend ein effektives Instrument zur Bekämpfung von Langzeitarbeitslosigkeit darstellt. Abschließend beschäftigt sich die Dissertationsschrift mit der Untersuchung der Effektivität von AAP zur Verbesserung der Arbeitsmarktchancen von arbeitslosen Jugendlichen. Jugendliche sind im Gegensatz zu Erwachsenen häufiger von Arbeitslosigkeit betroffen, da sie über geringere Such- bzw. Arbeitserfahrung verfügen. Die Bekämpfung von Jugendarbeitslosigkeit steht daher im Fokus der AAP. Vor diesem Hintergrund ist es erstaunlich, dass bisher nur wenig über die Wirksamkeit von AAP für arbeitslose Jugendliche bekannt ist bzw. für Deutschland hierzu noch überhaupt keine Erkenntnisse existieren. Die Dissertationsschrift liefert nun erstmalig Evidenz zur Wirksamkeit von AAP für arbeitslose Jugendliche in Deutschland. Die untersuchten Programme (außer Arbeitsbeschaffungsmaßnahmen) erhöhen die Beschäftigungswahrscheinlichkeit der Teilnehmer gegenüber den Nicht-Teilnehmern. Allerdings zeigt sich auch, dass arbeitslose Jugendliche ohne bzw. mit Hauptschulabschluss weniger von einer Programmteilnahme profitieren als Jugendliche mit einer höheren Schulbildung. Hier scheint noch Optimierungsbedarf zu bestehen, indem die Ausgestaltung der AAP stärker auf die Bedürfnisse von geringqualifizierten Jugendlichen eingehen sollte.

Abstract:
This thesis is concerned with effects of spin polarization in neutron stars. In particular, we focus on static and dynamic properties of dense neutron matter. We use two different kind of potential to perform our studies: the phenomenological two-body Argonne V$8$' potential plus the three-body Urbana IX force and a modern local version of chiral effective potential up to next-to-next-to-leading order (N$2$LO). Estimates are calculated for the neutrino mean free path in partially spin-polarized neutron matter starting from Quantum Monte Carlo (QMC) simulations and using mean-field approaches to compute the response function in the longitudinal and transverse channel. We also compute magnetic susceptibility of dense neutron matter from accurate QMC calculations of partially spin-polarized systems. Twist-averaged boundary conditions (TABC) have been implemented to reduce finite-size effects. In the results, we also account for the theoretical uncertainty coming from the chiral expansion scheme. These results may play a role in studying high-energy phenomena such as neutron star mergers and supernova explosions, although they have been computed only at T$=0$ K.

Full text
Abstract:
Bei der theoretischen Beschreibung von spektroskopischen Experimenten wird in der Regel das Materiesystem quantenmechanisch beschrieben, während das Strahlungsfeld klassisch behandelt wird. Diese semiklassische Näherung ist zur Beschreibung von Experimenten, bei denen eine starke Kopplung zwischen dem Matriesystem und einzelnen Photonen besteht, nicht mehr gültig. Dies kann beispielsweise innerhalb eines optischen Resonators der Fall sein. In dieser Arbeit wird am Beispiel eines Pump-Test- Experiments zum Nachweis des optischen Stark-Effekts untersucht, welche zusätzlichen Effekte sich bei einer quantisierten Beschreibung des Strahlungsfeldes ergeben. Ein signifikanter Effekt ist, dass die Photonenstatistik des Pumpfeldes sich in der Linienform der verschobenen Resonanzlinie widerspiegelt. Weiter wurde in dieser Arbeit bei kleiner Pumpverstimmung ein Verstärkungseffekt gefunden, der ebenfalls auf der quantisierten Behandlung des Strahlungsfeldes beruht (nichtklassische Verstärkung). Es treten ferner bei grosseren Ensemblen von Zwei-Niveau -Systemen zusätzliche Unterstrukturen und Resonanzen auf. Auch kann der Nachweis des optischen Stark-Effekts Aufschluss über die Nichtdiagonalelemente bezüglich der Photonenzahl des quantisierten Pumpfeldes geben.Im Hinblick auf die Beschreibung komplexer Materiesystemen wurde in dieser Arbeit auch eine näherungsweise Berechnung der Testabsorption mit quantisiertem Strahlungsfeld im Rahmen einer Dichtematrixtheorie untersucht. Insbesondere war hier für die quantitative Beschreibung der nichtklassischen Verstärkung eine Berücksichtigung hoherer Korrelationen zwingend erforderlich. Auch wurden näherungsweise Entkopp- lungen unter Berücksichtigung der Erhaltungsgrossen durch- geführt. Die Dichtematrixtheorie wurde auf die Untersuchung des optischen Stark-Effektes an storstellengebundenen Exzitonen in Halbleitern angewandt. Da diese Resonanzen vergleichsweise kleine homogene und inhomogene Linienbreiten aufweisen,ist hier experimentell zu erwarten, dass sich feine Effekte des quantisierten Pumpfeldes bemerkbar machen konnen.
The theoretical description of spectroscopic experiments usu ally relies on a semiclassical approach where the matter system is described in terms of quantum mechanics while the radiation field is treated classically. This approach does n ot work well for systems with a strong coupling between the matter system and photons of the radiation field. The latter can be the case within an optical resonator.In this thesis, additional effects of a quantized radiation field are inves tigated on a pump-probe experiment for detecting the optical Stark effect. One significant effect is that the lineshape of the shifted resonance displays the photon statistics of the pump field. For small pump detuning probe gain results in a frequency regime where the semiclassical treatment predicts absorption. This effect is refered to nonclassical gain. For larger ensembles of two-level systems, additional substructures and resonances appear within the probe absorption spectrum. Also non- diagonal elements of the field density matrix can be detected in such an experiment. In order to describe a more complex matter systems, the optical Stark effect has been treated in terms of a density matrix approach with quantized radiation fields. For a quantitative description of nonclassical gain, higher correlation terms had to be treated properly. Moreover, conserved quantities were taken into account in approximate decouplings. The density matrix approach was applied to the description of the optical Stark effect on impurity-bound excitons in semiconductors. These systems are of high interest as their narrow resonances might allow the demonstration of fine effects of the quantized radiation field.

Abstract:
L'objectif de ce mémoire est de présenter une étude aussi complète que possible de l'effet Stark dans les molécules en général, et dans les molécules tétraédriques en particulier. Après une description du modèle de matrice 2*2 utilisé usuellement pour l'étude de l'effet Stark en champs électriques faibles, notamment pour la détermination des paramètres du moment dipolaire induit par la vibration et par la rotation de la molécule, nous présentons un modèle plus général adapté à des études en champs plus forts et incluant dans l'hamiltonien Stark aussi bien le moment dipolaire que la polarisabilité de la molécule. Nous avons également mis au point un modèle pour calculer les intensités des transitions infrarouges et Raman entre les niveaux d'énergie Stark. Avec ces modèles nous avons déterminé quelques paramètres du moment dipolaire induit des molécules SiF4 et SnH4. Nous avons également effectué des prédictions de spectres d'effet Stark linéaire et non linéaire, en fréquences et en intensités de la molécule SiF4. Ces prédictions sont comparées à des spectres expérimentaux. Enfin, nous avons procédé à une étude approfondie du modèle de l'hamiltonien Stark effectif, et montré que plusieurs jeux de paramètres cohérents du moment dipolaire et de la polarisabilité conduisent aux mêmes valeurs propres. Ceci met en évidence l'ambiguïté de l'hamiltonien Stark effectif. Par ailleurs, nous discutons la contribution de la polarisabilité dans l'effet Stark et des limites du modèle en champs forts

Full text
Abstract:
The performance of an adaptive optics system using a single laser guide star is constrained by laser guide star anisoplanatism and the characteristics of available lasers. Improved performance is theoretically achievable through the use of multiple laser guide stars. Earlier results on wavefront reconstruction in laser guide star systems1 are extended to this more general case. General reconstruction algorithms are evaluated using a linear systems model which accounts for the partially correlated effects of laser guide star anisoplanatism, laser guide star position uncertainty, wavefront sensor noise, deformable mirror fitting error, aperture edge effects and control loop servo bandwidth. Reconstructor wavefront estimation accuracy is optimized subject to linear constraints imposed to insure control loop stability. Reconstructor performance is quantified in terms of the optical system’s modulation transfer function for a system including a 3.5-m primary, a deformable mirror with from 341 to 771 actuators, and a constellation of one or several laser guide stars. The addition of a single, low power, resonant sodium guide star greatly improves the performance of a system using multiple Rayleigh backscatter laser guide stars.

Abstract:
It is well known that the use of a bright natural star as a reference source is limited by the angle of isoplanarity1,2,3 which usually does not exceed 10 angular seconds, while the sufficiency bright stars are located less closely. In this connection in recent years the formation technique of artificial guide stars is gathering force, based on the effect of laser backscattering in the atmosphere4,5.
