New developments in the pathogenesis of obesity-induced hypertension
2015
Obesity is a disorder that develops from the interaction between genotype and environment involving social, behavioral, cultural, and physiological factors. Obesity increases the risk for type 2 diabetes mellitus, hypertension, cardiovascular disease, cancer, musculoskeletal disorders, chronic kidney and pulmonary disease. Although obesity is clearly associated with an increased prevalence of hypertension, many obese individuals may not develop hypertension. Protecting factors may exist and it is important to understand why obesity is not always related to hypertension. The aim of this review is to highlight the knowledge gap for the association between obesity, hypertension, and potential …
Effects of non-tracking solar collector orientation on energy production : photovoltaic systems
2012
Abstract: This Master's thesis proposes a new method for calculating the optimum tilt and orientation angle of a fitted solar collector. In addition to using geographical data, this method takes into account the radiation data and weather statistics of prospective locations. This makes the calculations valid not only for certain latitudes, but also for certain radiation and weather conditions. Calculations were done by estimating the energy production of a given solar array using a sequence of different tilt angles and orientation angles. Special attention was given to shaded solar arrays and arrays made up of photovoltaic modules. Specific radiation and weather data was used for both locat…
Influence of Oral Health Care Systems on Future Career Environment of Dental Students in Europe
2021
Oral healthcare is organized subsidiarily and independently by nation states in Europe and also within the EU and consequently, major differences between the nation states and the various oral healthcare systems in Europe are present. The socialization in the respective catchment area can have an impact on the job choice and the perception of employment opportunities of different professional groups. Therefore, the purpose of this survey was to elucidate the influence of different oral healthcare systems on students living or studying in the respective catchment area. A questionnaire (in English, French, German, Italian, and Spanish) with 18 different components was administered. Data on ge…
UV filters: From sunscreens to human body and the environment
2007
Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…
Noziedzīgi iegūtu līdzekļu legalizācijas un terorisma finasēšanas novēršanas nozares tiesiskā regulējuma nepilnības banku sektorā.
2020
Noziedzīgi iegūtu līdzekļu legalizācijas un terorisma finansēšanas novēršanas (turpmāk NILLTFN) joma ir kļuvusi ļoti aktuāla gan valsts līmenī, gan starptautiskā līmenī. Kredītiestādes ir vienas no galvenajiem NILLTFN likuma subjektiem. Ņemot vērā jaunākās tendences NILLTFN jomā, kredītiestāžu topošajiem un esošajiem klientiem, nākas saskarties ar virkni sarežģījumiem darījumu attiecībās ar kredītiestādēm. Kredītiestādēm ir uzlikts pienākums un ievērojama atbildība pārzināt savus klientus un klientu veiktos darījumus. Uzraugošās institūcijas (FKTK) sodi pret kredītiestādi, ja kredītiestādes neizpilda NILLTFN likuma prasības var izpausties kā naudas sodi vai pat licences anulēšana. Lai izvai…
Apstākļu izmaiņu klauzula civiltiesībās.
2017
Maģistra darba uzdevums ir izpētīt apstākļu izmaiņas klauzulas attīstību, noskaidrot tās piemērošanas kritērijus un tiesiskās sekas, izpētīt normatīvo regulējumu starptautiskajās tiesībās un citu valstu nacionālajos normatīvajos regulējumos. Darba mērķis ir noskaidrot apstākļu izmaiņas klauzulas vietu un tās nepieciešamību Latvijas civiltiesībās. Tēmas aktualitāte ir pamatota ar to, ka apstākļu izmaiņas doktrīna iegūst arvien lielāku popularitāti starptautiskajos unifikācijas dokumentos, kas ir vērsti uz civiltiesību modernizāciju, un lielākajā daļa Eiropas valstu nacionālajos normatīvajos aktos. Pētījuma rezultātā autors sniedz savu skatījumu par svarīgiem apstākļiem attiecībā uz apstākļu …
