Opis:
The study was aimed at determining the age-depended changes in insulin-like growth factors 1 and 2 (IGF-1 and IGF-2) mRNA levels in relation to the gastrointestinal tract (GIT) development in newborn calves. Twenty four male calves (5-day-old) were randomly allocated to 4 groups which were slaughtered at day 5, 12, 19 and 26 of their life, respectively. Tissue samples from the rumen, abomasum, duodenum, jejunum and liver were taken for analysis, and the level of IGF-1 and IGF-2 mRNA was determined using RT semi-quantitative PCR method. Both IGF-1 and IGF-2 mRNA level was the biggest on 5 day of life, significantly decreased up to day 12-19 in most of analyzed GIT parts, and started to increase thereafter. In the rumen the reduction in the amount of IGFs transcripts was associated with the reduction in papillae length and tunica muscularis thickness. The abomasum weight and tunica mucosa thickness increased from the 5 day up to 19 day of life, whereas abomasal IGF-1 mRNA level decreased together with calf's age up to 19 day of life, and the level of IGF-2 mRNA did not change. The reduction in IGFs mRNA level after 5 day of life in the duodenum (IGF-1 and IGF-2) and in the jejunum (IGF-1) was associated with reduction in villi length (duodenum and jejunum), and the increase of crypt depth (duodenum).

Opis:
Business processes are omnipresent in nowadays economy: companies operate repetitively to achieve their goals, e.g., deliver goods, complete orders. The business process model is the key to understanding, managing, controlling, and verifying the operations of a company. Modeling of business processes may be a legal requirement in some market segments, e.g., financial in the European Union, and a prerequisite for certification, e.g., of the ISO-9001 standard. However, business processes naturally evolve, and continuous model adaptation is essential for rapid spot and reaction to changes in the process. The main contribution of this work is the Continuous Inductive Miner (CIM) algorithm that discovers and continuously adapts the process tree, an established representation of the process model, using the batches of event logs of the business process. CIM joins the exclusive guarantees of its two batch predecessors, the Inductive Miner (IM) and the Inductive Miner – directlyfollows-based (IMd): perfectly fit and sound models, and single-pass event log processing, respectively. CIM offers much shorter computation times in the update scenario than IM and IMd. CIM employs statistical information to work around the need to remember event logs as IM does while ensuring the perfect fit, contrary to IMd.
