Determination of N-acetyl-l-glutamine in urine by HPLC
1986
The determination of N-acetyl-l-glutamine (AC-GLN) in urine of rats after derivatization with xanthydrol by HPLC is described. The urine samples were collected from two groups of rats, one group fed normal nutrition, the other treated with AC-GLN. About 5 mM/l AC-GLN was detected in urine of untreated animals, whereas the excretion of the other group was in the range of 50 mM/l corresponding to about 50 wt.-% of the given AC-GLN.
Determinants of Chairman Compensation
2011
This study examines determinants of chairman compensation in a supervisory board setting and, specifically, the relationship between chairman and CEO compensation. Using a sample of publicly listed firms in Sweden, the study indicates that chairman compensation – despite its fixed nature – is reflective of firm performance via a positive relationship to CEO compensation. As CEO compensation is set before chairman compensation, we argue that the chairman may be inclined to conspire with the CEO in earnings management efforts at the expense of monitoring on behalf of investors. Supporting our argument, we find evidence that the gap between chairman and CEO compensation is less at firms where …
Tour Leaders' Impression Management and Job Performance: Exploring the Moderating Role of Tourists' Self-Monitoring
2012
A tour leader (TL) is a first-line service provider whose performance shapes a tourist's experience and satisfaction during a journey. We examine the moderating effects of the self-monitoring level of group package tour members on the relationship between the use of impression management (IM) tactics by TLs and tourists' subsequent job performance ratings (PRs) of a TL. Data from 485 responses of tourists from 59 outbound tour groups in Taiwan revealed that TLs' use of positive IM tactics – that is, ingratiation, self-promotion, and exemplification – is positively related to tourists' PRs. In contrast, their use of non-positive IM tactics – that is, supplication and intimidation – is negati…
Do non-responders to resistance training exist in professional sport?
2020
Resistance training (RT) is the most popular form of exercise that exerts several benefits (muscle hypertrophy and strength). Furthermore, we are witnessing several athletes competing at the highest level of their respective sport have undergone an enormous physical transformation. Nonetheless, lack of RT training, especially after a long detraining period, causes loss of muscle mass, and consequently, a decreased muscle strength, power, and lower muscle activation, and consequently, performance deterioration. In light of these facts, several authors recently have arisen the existence of responders and non-responders to RT. In order to improve athletic performance, the scientific community …
Extraversion and performance approach goal orientation : An integrative approach to personality
2019
Abstract Research shows that extraversion is unrelated to performance approach goal orientation, both at the trait- and the state-level. However, since previous studies have either focused on the trait- or the state-level, such a conclusion may be premature. Building upon the idea that acting against one’s trait consumes self-control resources, we reason that within-person deviations from one’s level of trait extraversion might negatively relate to performance approach goal orientation. Using experience sampling data from 47 employees across 10 days (N = 307), we found that deviations from one’s trait extraversion levels are associated with lower levels of performance approach goal orientat…
Bayesian forecasting of demand time-series data with zero values
2013
This paper describes the development of a Bayesian procedure to analyse and forecast positive demand time-series data with a proportion of zero values and a high level of variability for the non-zero data. The resulting forecasts play decisive roles in organisational planning, budgeting, and performance monitoring. Exponential smoothing methods are widely used as forecasting techniques in industry and business. However, they can be unsuitable for the analysis of non-negative demand time-series data with the aforementioned features. In this paper, an unconstrained latent demand underlying the observed demand is introduced into the linear heteroscedastic model associated with the Holt-Winters…
Studies of polyamines transport through liquid membranes with D2EHPA as a carrier.
2008
The transport of polyamines through the liquid membranes with di‐2‐ethylhexyl phosphoric acid (D2EHPA) was investigated. The study was performed in three main steps: liquid–liquid extraction (LLE), bulk liquid membrane (BLM) extraction, and supported liquid membrane (SLM) extraction. Equilibrium distribution experiments allowed determining the extraction constants and stoichiometric coefficients for each polyamine. It turned out that one amino group binds two molecules of carrier (one D2EHPA dimer) and the extractability of polyamine rises with the increase in number of function groups in the molecule. The BLM and SLM experiments showed that despite considerable differences in distribution …
Vigor F7 projekta ietekme uz redzes funkcijām
2017
Maģistra darbs ir uzrakstīts angļu valodā uz 38 lapām. Tas satur 12 attēlus, 9 tabulas, 26 atsauces uz literatūras avotiem un 4 pielikumus. Galvenais darba mērķis ir nodemonstrēt F7 ierīces ietekmi uz redzes sistēmu un tās funkcijām. Tika veikti divi eksperimenti: Eksperiments I (30 dalībnieki, 10 – 40 g.v.), lai izvērtētu Vigor F7 ierīces ietekmi uz redzes funkcijām; Eksperiments II (20 dalībnieki, sportisti, 14 – 48 g.v.), lai izvērtētu Vigor F7 ierīces ietekmi uz dinamisko iemaņu efektivitāti. Abos eksperimentos novēroja statistiski nozīmīgi atšķirīgus rezultātus gan redzes funkcijām, gan dinamiskajām iemaņām, ja izmantoja F7 ierīci.
Fenibuta piemaisījumu kvantitatīvas noteikšanas metodes optimizācija un validācija
2021
Kokina. P., zinātniskie vadītāji: Dr. ķīm. V. Bartkevičs (LU), Dr. ķīm. A. Bolotin (AS Olainfarm). Maģistra darbs, 147 lappuses, 184 attēli, 75 tabulas, 15 literatūras avoti, 16 pielikumi. Latviešu valodā. Maģistra darbā ir veikta divu piemaisījumu(4-amino-3-fenilbutānskābes etilestera hidrohlorīds un 4-fenil-2-pirrolidons) kvantitatīvas noteikšanas analīzes metodes optimizācija un validācija farmaceitiskā preperāta Noofen® aktīvajai farmaceitiskai vielai (AFV) fenibuts. Metodes optimizācija un validācija bija nepieciešama farmaceitiskā preparāta Noofen® kvalitātes kontroles vajadzībām.
