2020
The 1,3-dipolar cycloaddition reaction is one of the most rapid, and efficient protocols to access, and construct highly divergent heterocycle chiral auxiliaries. Free catalyst synthesis of spirooxindole scaffold incorporating sulphone moiety via one pot&ndash
X-Ray structure, Hirshfeld analysis and DFT studies of two new hits of triazolyl-indole bearing alkylsulfanyl moieties
2021
Two new hits of triazolyl-indole containing two different alkylsulfanyl analogues named tert-butyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 2, and ethyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 3 were synthesized via reaction of 4-amino-5-(1H-indol-2-yl)-1,2,4-triazol-3(2H)-thione 1 with tert-butyl bromoacetate and ethyl chloroacetate in the presence of base (Et3N). The molecular structure of 2, and 3 was confirmed by single-crystal X-ray diffraction and 1H/13C- NMR spectroscopic techniques. In compound 2, the molecular packing depends on significant O...H (9.3%), N...H (12.4%) and S...H (3.1%) as well as relatively weak C...H (14.1%), S...C (…

The Sound of Sadness : The Effect of Performers' Emotions on Audience Ratings
2013
Very few studies have investigated the effect of performers’ felt emotions on the audience perception of their performances. Does it matter what a performer feels or thinks about when performing? To investigate this, we asked four violinists to play the same musical phrase in response to three different instructions. The first in-struction was to focus on the technical aspects of their playing. The second instruction was to give an expres-sive performance. Following a sadness-inducing mood induction task, the third instruction was to play while focusing on their felt emotions. High quality audio and motion-capture recordings were made of all perfor-mances. Subsequently, motion-capture anima…
A/S "Citadele banka" kredītportfeļa analīze
2019
Bakalaura darbs par A/S „Citadele banka” kredītportfeļa analīzi veidots, lai pētītu šīs komercbankas kredītportfeļa struktūru un dinamiku, kā arī kredītportfeļa ienesīgumu un kvalitāti, balstoties uz pirmajā nodaļā analizētās literatūras avotiem. Šo analīzi veikt ir svarīgi, jo komercbanku darbības sektoram ir liela ietekme uz valsts ekonomisko situāciju. Un tā kā bankas kredītportfelis sastāda lielāko daļu no bankas kopējiem aktīviem, kā arī ir viens no svarīgākajiem un ienesīgākajiem bankas peļņas avotiem, ir svarīgi, lai tas nepārtraukti tiktu uzlabots. Un, lai to varētu uzlabot, nepieciešams veikt regulāru finanšu analīzi. Bakalaura darba mērķis ir , izmantojot un pamatojoties uz zinātn…
A long-snouted late Eifelian arthrodire from Aragon (Spain)
2021
Carolowilhelmina geognostica Carls, 1995 is a large arthrodire (Placodermi) from the Tortodus kockelianus Conodont Zone, late Eifelian, in the Eastern Iberian Cordillera in southern Aragon. The somewhat incomplete but articulated skull is preserved, showing a long tubular rostral plate, very small postnasal plates, low toothless inferognathals, and a small, slender and flat parasphenoid. Supraorbital and central sensory lines meet their antimeres at the midline of the skull, forming a straight double line. Lines along the ventral surface of the rostral plate probably belong to the suborbital branches of the infraorbital sensory lines. The combination of characters of Carolowilhelmina points…
Does stump removal affect early growth and mycorrhizal infection of spruce (Picea abies) seedlings in clear-cuts?
2012
Abstract Stump removal procedure increases the extent of exposed mineral soil in the clear felled areas. In this study, our aim was to find out whether the early growth and mycorrhization of Norway spruce (Picea abies (L.) Karst.) seedlings differ between stump removal and mounding sites. Stumps were harvested from five one-hectare study sites and other five sites were mounded after clear felling. Twenty seedlings were planted on mounds at each study site. Although the height of spruce seedlings did not differ between the treatments after three growing periods, their mean growth was ca. 10% higher at the stump removal sites. The community of ectomycorrhizal (ECM) in the seedling roots did n…
Synthesis, Structure and Antimicrobial Activity of New Co(II) Complex with bis-Morpholino/Benzoimidazole-s-Triazine Ligand
2023
A new Co(II) perchlorate complex of the bis-morpholino/benzoimidazole-s-triazine ligand, 4,4′-(6-(1H-benzo[d]imidazol-1-yl)-1,3,5-triazine-2,4-diyl)dimorpholine (BMBIT), was synthesized and characterized. The structure of the new Co(II) complex was approved to be [Co(BMBIT)2(H2O)4](ClO4)2*H2O using single-crystal X-ray diffraction. The Co(II) complex was found crystallized in the monoclinic crystal system and P21/c space group. The unit cell parameters are a = 22.21971(11) Å, b = 8.86743(4) Å, c = 24.38673(12) Å and β = 113.4401(6)°. This heteroleptic complex has distorted octahedral coordination geometry with two monodenatate BMBIT ligand units via the benzoimidazole N-atom and four water …
IDENTIFYING THE TRAINING NEEDS AND THE KEY TRAINING TOPICS IN THE ENTERPRISES OF LATVIA
2019
The role of a workplace in the provision of lifelong learning processes is increasingly emphasised in the academic discourse. Since the early 21st century, a new term – “workplace pedagogy” (Billet, 2000) – has appeared, which signifies the increasingly important role of the workplace in the process of adult learning. The goal of this article is to discuss the key principles in determining the training needs and the key training topics in the enterprises of Latvia. The author of the article has carried out a qualitative study using a partially structured interview method. Four heads of human resource departments have been interviewed in four enterprises of Latvia with varied capital and wit…
Repercusiones de factores de personalidad en la felicidad, calidad de vida y la satisfacción laboral del personal de enfermería
2014
El presente trabajo quiere aportar algo de luz sobre el papel que juegan las características individuales de las enfermeras en la felicidad, calidad de vida y satisfacción laboral. Igualmente queremos saber en que medida la felicidad y la calidad de vida contribuyen a la satisfacción laboral, la actitud general de un individuo hacia su empleo, hacia su trabajo. Teniendo esto en cuenta, consideramos que, si queremos ver los factores que intervienen en la satisfacción laboral esto es, en la “falta de estrés”, debemos de estudiar aquellas variables que se han considerado favorecedoras del estrés, pero también las contrapuestas, es decir las que tienen un efecto “buffer” sobre el estrés. A este…
