Przyczynek do kwestii estetycznej około roku 1897

2017

A ąuestionnaire on “the essence and goal of a novel” published in 1897 in “Kurier Niedzielny” is an interesting documentation of aesthetic views of writers and literary critics in the late 19th century. Representatives of all literary generations of that time - from pre-positivists through two generations of Polish positivists to Young Poland writers - speak in favor of moderate aestheticism protesting against bias in literaturę and defend the autonomy of an artist. Quotes from participants exhibit good command of both idealistic (post-Hegel) aesthetic tradition and emotionalistic concepts of Positivism. They also foreshadow aesthetic predilection of Modemism. They do not provide an in-dept…

Paisaje y nacionalismo en el primer franquismo

2016

Assuming the theoretical idea widely developed by Human Geography that landscapes are cultural constructions with the capacity to become symbolic elements within nationalist discourses, this article explores the context of early Francoism. The aim of these pages is to analyze landscape sensibility as well as the landscape idea developed by the francoist nationalist discourse by trying to draw out three inherent elements in it: first of all, following Oliver Zimmer’s work, the nationalization of nature, this is to say, the consideration that nature expresses the community’s myths, events or memories; secondly, the naturalisation of the nation, that projects upon landscapes the capacity to de…

Effectiveness of sodium bicarbonate combined with hydrogen peroxide and CPP-ACPF in whitening and microhardness of enamel

2017

Background: This study investigated the effects of sodium bicarbonate (NaHCO3) combined with 1.5 hydrogen peroxide (H2O2) and casein phosphopeptide amorphous calcium phosphate fluoride (CPP-ACPF) on color and microhardness of enamel. Material and Methods: Seventy-five bovine incisors were immersed in a tea solution for 7.5 days. The specimens were randomly divided into five groups according to the whitening agent applied: 1) 94 NaHCO3, 2) a blend of 94 NaHCO3 and CPP-ACPF, 3) a blend of 94 NaHCO3 and 1.5 H2O2, 4) a blend of 94 NaHCO3, 1.5 H2O2 and CPP-ACPF, 5) control. The whitening procedure was performed for 10 times over 10 days. At each day, the buccal surfaces were covered with whiteni…

Repeated exposure of acidic beverages on esthetic restorative materials: An in-vitro surface microhardness study.

2015

Background A manifold increase in the consumption of aerated beverages has witnessed a twin increase in tooth wear and raised demand for esthetic restorative materials. This study aimed to evaluate the surface microhardness changes of esthetic restorative materials following treatment with aerated beverages in an in-vitro situation. Material and Methods The initial surface microhardness of the restorative materials GC Fuji II LC, GC Fuji IX, Nano Glass ionomer, Resin and Nano composite was recorded. These materials were studied under 3 groups that included those exposed to the acidic beverages daily, weekly once in a month and those that had no exposures at all. The final surface microhardn…

Aesthetic considerations for the min-max K-Windy Rural Postman Problem

2017

[EN] The aesthetic quality of routes is a feature of route planning that is of practical importance, but receives relatively little attention in the literature. Several practitioners have pointed out that the visual appeal of a proposed set of routes can have a strong influence on the willingness of a client to accept or reject a specific routing plan. While some work has analyzed algorithmic performance relative to traditional min-sum or min-max objective functions and aesthetic objective functions, we are not aware of any work that has considered a multi-objective approach. This work considers a multi-objective variant of the Min-Max K-Vehicles Windy Rural Postman Problem, discusses sever…

Language constraints in producing prefiguration posters for a scientific exhibition

1997

The museographic transposition of scientific knowledge leads notably to the preparation of exhibition posters. This is a delicate operation, on account of the constraints imposed by space, language, concepts and the text. These difficulties are even greater in the case of bovine reproduction biotechnologies, such as cloning, where knowledge is not yet stable. This paper deals with the choices made during the phase of museographic transposition. First of all, based on an epistemological approach, a historical analysis of knowledge-building underpins the choice of information to be presented. Language is then selected according to the linguistic analysis of a series of articles which popular…

Challenging serve myths in doubles tennis

2021

Doubles tennis has received little interest from quantitative research to date. Coach-led anecdotes therefore abound. The aims of this study were therefore to evaluate the veracity of the following common anecdotes: (a) serving teams have an advantage regardless of the length of the point; (b) serving teams have a greater advantage with new balls; (c) regular teams perform better when serving than new teams and (d) serving teams decrease their performance during break points. Data from doubles hard-court and clay-court tennis were collated for 52 doubles teams during 2018 ATP tournaments. Results revealed that the advantage of serving teams was evident on the points lasting up to 4 shots. …

Effect of in-office bleaching gels with calcium or fluoride on color, roughness, and enamel microhardness

2019

Background Commercial bleaching gels with remineralizing agents were developed to reduce the adverse effects of dental bleaching. The present study evaluated the effects on teeth of in-office bleaching gels containing 35-40% hydrogen peroxide (HP) with Calcium (Ca) or Fluoride (F). Material and methods Bovine enamel/dentin blocks (4x4x2.5 mm) were randomly divided into the following groups (n=12): no treatment (control); 35% HP (Whiteness HP, FGM); 35% HP with Ca (Whiteness HP Blue, FGM); 40% HP with F (Opalescence Boost, Ultradent). The specimens were analyzed for color (ΔL*, Δa*, Δb*, and ΔE), roughness (Ra), and Knoop microhardness (KHN). The color and KHN data were submitted to ANOVA an…

Implant Abutment Cleaning by Plasma of Argon: 5-Year Follow-Up of a Randomized Controlled Trial.

2015

Contamination of implant abutments could potentially influence the peri-implant tissue inflammatory response. The aim of the present study is to assess the radiographic bone changes around customized, platform-switched abutments placed according to the "one-abutment-one-time" protocol, with and without plasma of argon cleaning treatment.Thirty healthy patients with thin gingival biotype (1 mm) and history of periodontal disease received one maxillary implant each. Immediately before abutment connection, patients were randomly assigned to control group (cleaning protocol by steaming) or test group (plasma of argon treatment). Outcome measures were: 1) success rate of implants and prostheses;…
