Presbyopia and the aging eye: Existing refractive approaches and their potential impact on dry eye signs and symptoms.
2020
Every part of the human body is subject to aging, including the eye. Increased prevalence of dry eye disease with age is widely acknowledged: aging threatens ocular surface homeostasis, altering the normal functioning of the lacrimal functional unit and potentially leading to signs and symptoms of dry eye. Parallelly, two additional degenerative processes take place within the crystalline lens, leading to presbyopia and cataractogenesis. With continuously increasing life expectancies both conditions are expected to impact society further. Correction strategies for presbyopia and cataracts either directly or indirectly challenge ocular surface additionally. On one hand, contact lens presbyop…
¿Metrópolis dispersas?
2010
La cuestión de la dispersión urbana constituye hoy un tema de investigación alrededor del cual se ha ido concentrando el interés disciplinar y político-institucional. Tal interés encuentra su respuesta en datos estadísticos (EEA, 2006) que confirman que: el 75% de la población europea vive en áreas urbanas; más de un cuarto del territorio europeo resulta urbanizado, y según las estimaciones en 2020 aproximadamente cerca del 80% de los europeos vivirá en áreas urbanas. Es un campo de la investigación todavía abierto y sobre el cual este trabajo de tesis ha querido reflexionar, siendo consciente que en urbanismo el conocimiento es una acción cognitiva y, al mismo tiempo, proyectual. Por lo ta…
Evaluation of the use of wavefront encoding to reduce depth-induced aberration in structured-illumination microscopy
2018
Three-dimensional imaging is affected by depth-induced spherical aberration (SA) when imaging deep into an optically thick sample. In this work, we evaluate the impact of SA on the performance of incoherent grating-projection structured illumination microscopy (SIM). In particular, we analyze the reduction of the contrast in the structured pattern and compare the reconstructed SIM images for different amounts of SA. In order to mitigate the impact of SA, we implement and evaluate in SIM a wavefront encoded imaging system using a square cubic (SQUBIC) phase mask, an approach shown previously to be successful in conventional microscopy.
The Impact of CSR/ESG Reporting on the Cost of Capital: An Example of US Healthcare Entities
2021
PURPOSE: Identifying the direction and strength of the relationship between individual elements of ESG and ESG as a whole and the cost of capital (weighted average, equity, and debt) in the healthcare industry.
BETWEEN SUCCESS AND UNSUCCESS IN ABSORBING EU FUNDS - POLAND VS. ROMANIA
2015
Component of the cohesion policy promoted by the European Commission, European grant financing represents an inexpensive and important resource for the social and economic recovery of the member states, offering the prospect for the budgetary sustainability, encouraging public and private investments and thereby reducing the development gaps both at national and international level. In the present study, through the comparative analysis between Romania and Poland in the field of EU funds absorption, we intend to identify the weaknesses and the strengths of each of the two member states, helping to formulate a set of recommendations that our country should follow in order to attract funds re…
Bauskas novada Gailīšu pagasta Norvēģijas valdības divpusēja finanšu instrumenta atbalstītā projekta "Uzņēmējdarbības aktivitātes veicināšana Zemgale…
2020
Darba mērķis ir uz teorētisko un praktisko materiālu pamata veikt Norvēģijas valdības divpusējā finanšu instrumenta atbalstītā projekta “Uzņēmējdarbības aktivitātes veicināšana Zemgales reģiona pierobežas teritorijās” aktivitāšu kvantitatīvo rezultātu analīzi, salīdzināt analīzes rezultātus ar projekta uzstādītajiem, sākotnējiem mērķiem, kā arī novērtēt turpmākās šādu līdzīgu projektu ieviešanas iespējas. Pētījumu veido trīs daļas. 1. nodaļā tiek apskatīta uzņēmējdarbības attīstības nepieciešamība, atbalsta mehānismi un gan Latvijas, gan Eiropas Savienības atbalsts uzņēmējdarbībai un redzējums tās attīstībai. 2. nodaļā detalizēti tiek izpētīts EEZ un Norvēģijas valdības divpusējais finanšu …
Barbed Dental Ti6Al4V Alloy Screw : Design and Bench Testing
2023
Background context. Dental implants are designed to replace a missing tooth. Implant stability is vital to achieving osseointegration and successful implantation. Although there are many implants available on the market, there is room for improvement. Purpose. We describe a new dental implant with improved primary stability features. Study design. Lab bench test studies. Methods. We evaluated the new implant using static and flexion–compression fatigue tests with compression loads, 35 Ncm tightening torque, displacement control, 0.01 mm/s actuator movement speed, and 9–10 Hz load application frequency, obtaining a cyclic load diagram. We applied variable cyclic loadings of prede…
Single vector boson production in e(+)e(-) collisions at centre-of-mass energies from 183 to 209 GeV
2005
The cross sections for single vector boson production in the Wenu and Zee channels are measured from the data collected by AA the ALEPH detector at LEP for centre-of-mass energies between 183 and 209 GeV. These data correspond to a total integrated luminosity of 683 pb(-1). Single-W production is studied in both hadronic and leptonic decay channels. Hadronic and dimuon decays are used for single-Z production. The measured cross sections agree with the Standard Model predictions.
Klasiskie retorikas līdzekļi iedarbīgā mūsdienu publiskā runā
2015
Šī bakalaura darba tēma ir „Klasiskie retorikas līdzekļi iedarbīgā mūsdienu publiskā runā”. Veicot šo pētījumu, darba autore, pirmkārt, vēlas noskaidrot, vai tie retoriskie līdzekļi, kurus atklājuši tādi antīkie retorikas pētnieki kā Aristotelis, Cicerons un Kvintiliāns, joprojām ir aktuāli mūsdienās un, otrkārt, pievērst uzmanību šo instrumentu lietojuma biežumam pārliecinošā mūsdienu publiskā runā. Izmantotās pētījuma metodes ir apkopojoša analīze teorētiskajā daļā un diskursa kvalitatīva analīze empīriskajā daļā. Pētījuma rezultāti parāda, ka klasiskie retorikas līdzekļi joprojām ir piemērojami mūsdienu runām, un, lai pārliecinātu klausītājus, tie tiek bieži pielietoti mūsdienās.
