Aim. Cultivars of facultative and winter barley are planted at sowing in the fall. Evaluations of their photoreaction and vernalization requirement were conducted in the breeding stocks of the Institute to understand their adaptation to winter freezing. Methods. The trait levels were valued by heading date differences at planting in natural and short photoperiods after preliminary artificial seedling vernalization of various durations. Results. Facultative stocks showed only the strong photosensitivity without any requirement in vernalization whereas winter ones revealed significant vernalization requirement followed by photoreaction of various levels. In spite of the negative correlation of studied traits in the total set, it was positive significantly in the winter set as such. Conclusions. To breed winter barley stocks of strong photo-sensitivity is really possible by combining certain alleles of Vrn(=Sh) and Ppd gene systems. However, their effects on the final productivity at planting in the certain zones with specific environmental limits need additional investigations. And molecular marking and identification of these alleles require additional discussion to form a clear view of molecular variety coincidence with phenomenological effects of concrete alleles. Keywords: facultative and winter barley, genetic systems, photosensitivity, vernalization requirement, adaptation.

TAPPI test T811 is the specified method to ascertain ECT relative to box manufacturer’s certification compliance of corrugated fiberboard under Rule 41/ Alternate Item 222. T811 test sample heights were derived from typical board constructions at the time of the test method’s initial development. New, smaller flute sizes have since been developed, and the use of lighter weight boards has become more common. The T811 test method includes sample specifications for typical A-flute, B-flute, and C-flute singlewall (and doublewall and triplewall) structures, but not for newer thinner E-flute or F-flute structures. This research explores the relationship of ECT sample height to measured compressive load, in an effort to determine valid E-flute and F-flute ECT sample heights for use with the T811 method. Through this process, it identifies challenges present in our use of current ECT test methods as a measure of intrinsic compressive strength for smaller flute structures. The data does not support the use of TAPPI T 811 for ECT measurement for E and F flute structures, and demonstrates inconsistencies with current height specifi-cations for some lightweight B flute.

"Borderline Personality Disorder is a severe condition that affects self and interpersonal dimensions and emotional and behavioral regulation. Since the last decades of the 20th century, an impressive amount of research and clinical contributions on BPD came from specific fields such as psychiatry, clinical psychology, psychopharmacology, and, more recently, cognitive neuroscience. All contributions tackled the challenges of finding reliable diagnostic categories, highlighting detailed developmental trajectories, and fostering effective treatment protocols. However, as results come from different areas, it is often challenging to depict a coherent and yet multifaceted framework on this topic. In this study, we conducted a scientometric analysis of the available literature on BPD to provide a systematic and comprehensive overview of research on BPD and emphasize historical changes, intertwining between fields and new areas of investigation. Results clearly show the evolution of research on BPD starting from the initial development of the construct, passing through the studies on treatment efficacy, the results of longitudinal studies, the advances in cognitive neurosciences, and the recent dimensional conceptualization in DSM-5. Moreover, it emphasizes promising areas of investigation, such as the relations of BPD with NSSI, ADHD, and vulnerable features of narcissism."
