Johannes Audoenus († 1622): Die Bücher VIII-X
No full textDie letzte drei Bücher des neulateinischen Epigrammatikers werden untersucht sowie sein einziges bekanntes Autograph. Die Epigramme dieser dritten Trilogie werden neu thematisch geordnet, und zwar nicht gemäß den traditionellen Themen der Epigrammdichtung, sondern nach ihrem ideologischen Inhalt. Ihre Untersuchung wird vor dem Hintergrund ihrer Epoche angefertigt, aber mit der Intratextualität als Schwerpunkt; sie zielt darauf ab, die schriftstellerische Tätigkeit des britischen Martials hinsichtlich seiner Motivation und Ziele zu erhellen. Mit seiner schriftstellerischen Tätigkeit als Panegyriker am Hof von Adeligen mit politischer Macht (Maria Neville, Arabella Stuart, Prinz Henry von Wales und sein Bruder Charles, Edward Noel, William Sidley und Roger Owen) bezweckt John Owen Harmonie und rechte Ordnung im privaten und gesellschaftlichen Leben. Die Stabilisierung der politischen und ideologischen Situation in Großbritannien und der Tod des Prinzen Henry von Wales, des zukünftigen Thronfolgers und Hoffnungsträgers für Wales und Großbritannien, der auch der hauptsächliche Gönner Owens war († 1612), werden als Hauptursache dafür angesehen, daß Owen nach dieser dritten Trilogie (1612) nichts mehr veröffentlichte. Ebenso wird die turbulente Zeit der ersten Regenschaftsjahre von Jakob I., zugespitzt in der Pulververschwörung (1605), als die treibende Kraft dafür gehalten, daß die Epigramme Owens das Licht der Öffentlichkeit erblickten. Owen zeigt sich als Anhänger der via media in religiösen Themen; das μέτρον bildet bei ihm einen hohen Wert. Die Auseinandersetzung mit der Römischen Kirche wird vor dem Hintergrund des Versuchs Großbritanniens verstanden, sich von Rom loszulösen, womit eine Stabilisierung des kurz zuvor geschaffenen Vereinigten Königreichs einhergeht. Die neugegründete Anglikanische Kirche wird von Owen wie von einem ‘Walisen Barden’ propagiert. Festigung des Nationalgefühls und Kosmopolitismus stehen nebeneinander und ergänzen sich gegenseitig. Ein Autograph Owens bietet schließlich eine Verbindung zwischen dem Werk Owens, seinen Vorbildern und verwandten Formen und dem heutigen Leben
Evaluation of ecological factors that effect the appearance and growth of the forest species in N. E. Chalkidiki
No full textParametric frailty and shared frailty survival models
No full textFrailty models are the survival data analog to regression models, which account for heterogeneity and random effects. A frailty is a latent multiplicative effect on the hazard function and is assumed to have unit mean and variance theta, which is estimated along with the other model parameters. A frailty model is an heterogeneity model where the frailties are assumed to be individual- or spell-specific. A shared frailty model is a random effects model where the frailties are common (or shared) among groups of individuals or spells and are randomly distributed across groups. Parametric frailty models were made available in Stata with the release of Stata 7, while parametric shared frailty models were made available in a recent series of updates. This article serves as a primer to those fitting parametric frailty models in Stata via the streg command. Frailty models are compared to shared frailty models, and both are shown to be equivalent in certain situations. The user-specified form of the distribution of the frailties (whether gamma or inverse Gaussian) is shown to subtly affect the interpretation of the results. Methods for obtaining predictions that are either conditional or unconditional on the frailty are discussed. An example that analyzes the time to recurrence of infection after catheter insertion in kidney patients is studied.

No full textPartial Splenic Embolization: Successful treatment of hypersplenism, secondary to biliary cirrhosis and portal hypertension in cystic fibrosis
No full textAbstractPartial Splenic Embolization (PSE) is a non-surgical treatment for hypersplenism. It has been reported only in a limited number of patients with Cystic Fibrosis (CF). We report a case of a female cystic fibrosis patient who developed hypersplenism at the age of 14 and underwent PSE. Long term results over a period of 14 years after the procedure are presented
Basil functional and growth responses when cultivated via different aquaponic and hydroponics systems
No full textBackground Aquaponics is an innovative farming system that combines hydroponics and aquaculture, resulting in the production of both crops and fish. Decoupled aquaponics is a new approach introduced in aquaponics research for the elimination of certain system bottlenecks, specifically targeting the optimization of crops and fish production conditions. The aquaponics-related literature predominantly examines the system’s effects on crop productivity, largely overlooking the plant functional responses which underlie growth and yield performance. The aim of the study was the integrated evaluation of basil performance cultivated under coupled and decoupled aquaponic systems compared with a hydroponic one, in terms of growth and functional parameters in a pilot-scale aquaponics greenhouse. Methods We focused on the efficiency of the photosynthetic process and the state of the photosynthetic machinery, assessed by instantaneous gas exchange measurements as well as photosynthetic light response curves, and in vivo chlorophyll a fluorescence. Light use efficiency was estimated through leaf reflectance determination. Photosynthetic pigments content and leaf nutritional state assessments completed the picture of basil functional responses to the three different treatments/systems. The plant’s functional parameters were assessed at 15-day intervals. The experiment lasted for two months and included an intermediate and a final harvest during which several basil growth parameters were determined. Results Coupled aquaponics resulted in reduced growth, which was mainly ascribed to sub-sufficient leaf nutrient levels, a fact that triggered a series of negative feedbacks on all aspects of their photosynthetic performance. These plants experienced a down-regulation of PSII activity as reflected in the significant decreases of quantum yield and efficiency of electron transport, along with decreased photosynthetic pigments content. On the contrary, decoupled aquaponics favored both growth and photochemistry leading to higher light use efficiency compared with coupled system and hydroponics, yet without significant differences from the latter. Photosynthetic light curves indicated constantly higher photosynthetic capacity of the decoupled aquaponics-treated basil, while also enhanced pigment concentrations were evident. Basil functional responses to the three tested production systems provided insights on the underlying mechanisms of plant performance highlighting key-points for systems optimization. We propose decoupled aquaponics as an effective system that may replace hydroponics supporting high crops productivity. We suggest that future works should focus on the mechanisms involved in crop and fish species function, the elucidation of which would greatly contribute to the optimization of the aquaponics productivity
Effect of Pretreatments on Seed Germination of Prunus mahaleb L.
No full textSexual propagation of Prunus mahaleb is difficult due to seed dormancy. To overcome dormancy and maximize germination, various pretreatments have been applied, including stratification (warm and cold), gibberellic acid (GA3), sulfuric acid scarification (AS), and endocarp removal. The results show that warm stratification (WS) prior to cold stratification (CS) does not improve seed germination and a long period of WS (3 months) is disastrous for germination. CS alone (up to 4 months) has been found to hasten and increase seed germination. Pretreatment of the seeds with exogenous GA3, during the CS period, has been observed to result in significantly higher seed germination. AS of seeds for 45 minutes prior to GA3 (1000 ppm for 24 hours) plus CS (up to 1 month) pretreatment has been considered to reduce the mechanical resistance of endocarp and improve germination. However, extended time of AS (180 minutes) prior to GA3 plus CS pretreatment has been found to harm the seeds. The removal of endocarp has been noted to significantly improve germination. Seeds without endocarp, which were pretreated with GA3 (1000 or 2000 ppm for 24 hours) and then cold stratified for 1 month, have been noted to exhibit the highest germination percentages
On-line Powerplant Control using Near-InfraRed Spectroscopy : OPtiC-NIRS, REPORT 2021:746
No full textNear InfraRed Spectroscopy (NIRS) offers rapid on-line analysis of biomass feedstocks and can be utilized for process control of biomass- based combined heat and power plants. Within the OPtiC-NIRS project we have carried out a full-scale on-site testing of different NIRS for online powerplant control at the facilities of Mälarenergi and Eskilstuna Strängnäs Energi och Miljö. The project has been focused on developing and testing robust NIRS soft-sensors for fuel higher heating value and composition (incl. moisture, components such as recycle wood and glass, different type of plastics and ash) and combining them with dynamic models for on-line feed-forward process monitoring and control. Expected benefits include reduced risk of agglomeration and pollutant emissions formation as well as improved production control. A longer-term potential and ambition is to be able to identify the fossil content in municipal waste fuel, which can hopefully be addressed in a follow-up study. These are the results and conclusions of a project, which is part of a research programme run by Energiforsk. The author/authors are responsible for the content.</p
