Farmaceitisko līdzekļu potenciālā ietekme uz ūdens organismiem
2020
Pēdējos gados strauji pieaug vides piesārņojums ar farmaceitiskiem savienojumiem. Tie ir potenciāli bioaktīvi un var būtiski ietekmēt ūdens kvalitāti un ūdens organismus, tomēr par daudziem framaceitiskiem savienojumiem eko-toksikoloģiskā informācija ir nepilna vai pilnībā iztrūkst. Pētījums tika veikts ar mērķi noteikt plaši pielietojamu un ekotoksikoloģijā maz pētītu farmaceitisko produktu potenciālo ietekmi uz ūdens organismiem. Darba gaitā ir noskaidrotas preparātu LC50, EC50, LOEC un NOEC vērtības. Eksperimenta rezultāti parādīja, ka attiecībā uz ūdens organismiem testētiem preparātiem akūtos testos toksiskais efekts ir novērojams koncentrāciju robežās no 10 līdz 100 mg·l-1. Hroniskos …
The causal representation of outpatients with Crohn's disease: is there a link between psychological distress and clinical disease activity?
2013
Objectives: Because of the fluctuating and occasional character of Crohn’s disease (CD), patients have to cope with a changeable condition of health. Personal perceived control is known to be an important element of adaptation to their medical condition. The objectives of this work are to determine if perceived personal control is predictive of the clinical activity of the disease and of psychological distress (depression, anxiety). Methods: The Hospital Anxiety Depression Scale (HADS), the causal dimension scale and the Clinical Global Impression (CGI; assessing perceived severity) were administered to 160 patients affected by Crohn’s disease. Indicators of inflammation (CRP), disease dura…
IEEE Access Special Section Editorial: Exploiting the Benefits of Interference in Wireless Networks: Energy Harvesting and Security
2018
Interference used to be viewed as a harmful factor in wireless networks, which can reduce the quality of information transmission. To combat against interference, many interference management techniques have emerged. Due to the latest research advances, interference (or noise) can also be exploited to offer some benefits to wireless networks. The first aspect is that interference in multi-user networks can be collected as a green power supply for the transceivers, known as wireless energy harvesting. Another application is that one can generate artificial noise to disrupt the adversarial eavesdropping, and guarantee the security of wireless networks. Therefore, conventional interference man…
Wooden domes, vaulted and flat ceilings, partition walls in the Sicilian constructive tradition knowledge for the safeguard of architecture abd techn…
2014
The domes, vaulted and flat ceilings and also the partition walls built with wood and reeds had a particular diffusion from the XVII century, in Palermo as well as in other countries of Sicily, in many regions of Italy and in the whole Europe. The consolidated constructive tradition made them one of the most appreciated and usual systems for structural frame and for the definition of interior rooms, employed both for the monumental housebuilding and for that of minor importance, also owing to the adoption of economic materials. These wooden structures in the monumental architecture contain the rich pictorial and stucco decoration and define - together with other aspects of quality - the aul…
Antecedents and consequences of perceived investment value
2014
To gain a more comprehensive view to non-institutional investment behavior, this study develops and tests a set of hypotheses linking self-congruence, risk profile and investment experience with perceived investment value (PIV). In addition, the study tests direct and indirect effects of PIV on positive word-of-mouth. The hypotheses are tested on data from 440 private investors. The findings reveal that 1) self-congruence and risk profile are positively associated with five out of six of the PIV dimensions, 2) the relationship between PIV and word-of-mouth are more complex than is generally thought, and 3) user experience moderates four out of the twelve hypothesized paths. The study contri…
Uztvertā stresa, darba-ģimenes konflikta rādītāju saistība ar attālinātā darba biežumu
2021
Pētījuma “Uztvertā stresa, darba-ģimenes konflikta radītāju saistība ar attālinātā darba biežumu” mērķis bija noskaidrot kādas saistības pastāv starp uztverto stresu, darba-ģimenes konfliktu un attālinātā darba biežumu. Pētījuma izlase tika veidota pēc brīvprātības principa. Pētījumā piedalījās viena respondentu grupa, vecumā no 25-50 gadiem. Pētījumā piedalījās 53 respondenti (N 53) , tai skaitā 10 (19%) vīrieši un 43 (81%) sievietes. Pētījuma piedalījās respondenti, kuri ir attālinātā darba veicēji un ģimenē viens no vecākiem veic attālināto darbu 35 (66%) gadījumos vai abi vecāki ģimenē veic attālināto darbu 18 (34%) gadījumos. Visās respondentu ģimenēs klātesoši ir bērni. Viens bērns ir…
Customer Environmental Values and Their Contribution to Loyalty in Industrial Markets
2016
Concern over the effect of industries on the natural environment is growing on a multitude of levels. This study examines the effects of how perceptions of (a) environmental values, (b) green image and (c) perceived value of industrial customers influence their loyalty towards suppliers in existing relationships, and how the length of B2B relationships may moderate these linkages. A conceptual framework is developed and data are collected from a global sample (N =121) of B2B customers. We find that both green image and perceived value have a direct positive link with customer loyalty and that environmental values are positively linked to the green image of the supplier. Moreover, the effect…
Handel ludźmi zagrożeniem dla bezpieczeństwa wewnętrznego kraju
2017
Handel ludźmi to problem z jakim zmierzyć się muszą wszystkie kraje dbające o bezpieczeństwo swoich obywateli. Obowiązkiem państwa jest zapewnienie bezpieczeństwa swoim obywatelom, również jeśli chodzi o handel ludźmi. Autorka niniejszego artykuł zadaje pytanie, czy nasze państwo zapewnia poczucie bezpieczeństwa obywatelom w zakresie handlu ludźmi oraz czy organy państwa stworzyły system przeciwdziałania i zwalczania tego zjawiska, oparty na instytucjach organów administracji państwowej, jednostkach samorząduterytorialnego, organachściganiaiwymiarzesprawiedliwościoraz organizacjach pozarządowych, zapobiegający handlowi ludźmi.
La sépulture à char de La Tène A ancienne des “Craises” à Molinons (Yonne)
2013
The study reports on a chariot tomb excavated in 1985 at Les Craises in Molinons (Yonne). Set in an adventitious position in the midst of a monument with three quadrangular enclosures, the grave was of an adult of undetermined sex. Despite later pillaging, the goods found in this aristocratic tomb permit a dating to the second quarter of the 5th century BC, and an unusual cultural attribution, on the frontier in the Parisian Basin between the Jura culture to the south and the Marne-Moselle culture to the north.
