Vibrational relaxation of Na2 molecules in a triplet state: collisional transfer from a mixed A 1Σu+ − b3Πu gateway level to long-lived levels of b 3…
1997
Abstract Collision-induced vibrational transitions of Na2 within the b 3Π1u state have been observed in a free jet expansion, using two CW dye lasers for the pump and probe steps. The b-state is entered by the pump laser using a low mixed ( A 1 Σ u + − b 3 Π u ) level as a gateway. The occupations of various v′,J′-levels are studied as functions of the position in the flowing gas. The radiative lifetimes of Na2 in levels which had been populated by vibrational relaxation are found to be very long (> 4 μs). Cross-sections are estimated for vibrationally inelastic collisions with Na and Ar atoms.
Comparative analysis of direct and indirect costs of two minimally invasive techniques for the treatment of renal/ureteral calculi smaller than 2 cm
2020
[EN] Objective: To perform a comparative analysis of indirect and direct costs of two minimally invasive techniques (extracorporeal shock wave lithotripsy (ESWL) vs. ureteroscopy with holmium laser (URS/RIRS)) for the treatment of renal/ureteral calculi smaller than 2 cm. Material and methods: Prospective, comparative, non-randomized study of 84 patients treated for kidney stones smaller than 2 cm between January and December 2016. Of these, 38 (45.67%) were treated with ESWL (18 renal lithiasis and 20 ureteral lithiasis) and 46 (54.32%) with URS/RIRS (22 renal lithiasis and 24 ureteral lithiasis). A total of 19 (41.3%) patients in the URS/RIRS group and 15 (39.5%) patients in the ESWL grou…
The Nature Tour Mobile Learning Application. Implementing the Mobile Application in Finnish Early Childhood Education Settings
2014
This paper explores the process and impact of the implementation of the Nature Tour mobile learning application in Finnish early childhood education settings. The interest is to explore whether the concept of Nature Tour mobile application meets the needs of early childhood education in field trips. The idea of the mobile application is to help recording and comparing nature observations as well as to arouse children’s interest in nature. The feasibility of the mobile application was evaluated through a theoretical framework, which includes the core aspects of mobile learning. The evaluation framework consists of two levels titled core level and medium level. Three of the core level aspects…
Technical Note: Comparison of Techniques for Evaluating the Relative Preference by Sheep Among Saltbush Clones
2004
This research compared 4 field methods of evaluating the relative preference by sheep of 28 clones of saltbush (Atriplex halimus L.). The methods were as follows. 1) Leaf dots (LD): 8 leaves per shrub were marked on the lower surface with a small dot using a water-resistant, nontoxic ink. 2) Twig marks (TM): 2 current-year twigs per shrub were marked with 3 lines using the same ink approximately in the middle of the basal, median, and apical thirds. 3) Branch length (BL): 2 branches per shrub were marked with ink at the base of the current year's growth. The twigs were measured from the marked point to the top, before and after sheep browsing. 4) Ocular estimation (OE): the percentage of th…
Does Urban Security Modulate Transportation Choices and Travel Behavior of Citizens? A National Study in the Dominican Republic
2020
Introduction: Traditionally, the scientific literature on urban and transportation dynamics addresses many topics, but the security-related outcomes of users remain a pending issue, especially in emerging countries and their cities. Nevertheless, recent evidence suggests that, especially in developing countries, security issues may influence people’s decision-making in the choice of transport means, daily urban-trip patterns and road behaviors of users. Objective: The purpose of this study was to explore the relationships between the perceived security (in both urban environments and public transport systems) and the daily-travel behavior and trip patterns of the Dominican Republic populati…
Place Attachment and Its Consequence for Landscape-Scale Management and Readiness to Participate: Social Network Complexity in the Post-Soviet Rural …
2019
This paper uses the tripartite place attachment framework to examine six rural parishes across Estonia and Latvia. Existing analyses/frameworks on participatory processes often neglect the complexity of relationships that rural residents have to their local environments. From a qualitative analysis of face-to-face, semi-structured interviews with case study area inhabitants (23 interviews in Estonia and 27 in Latvia), we depict varying degrees of attachment of individuals to each other and to the place in which they live and their readiness to participate in terms of willingness and ability to participate in a landscape-scale management process. Attachment to the local area was strongest wh…
The Go2School project for promoting cycling to school: A case study in Palermo
2021
Abstract The identification of transport policy measures able to reduce the use of private cars for home-to-school travel is very relevant to reduce congestion during peak hours and to ensure that the areas around schools have livable environments. An action that policymakers could apply is promoting cycling to school through the introduction of bikesharing programs and creating safe routes to school through the construction of new cycle infrastructure. The aim of the paper has been, therefore, to assess if these policies could lead the high-school students to cycle to school, considering the city of Palermo as a case study. The goal is reached through the calibration of a modal choice mode…
Différences de genre et formes de dépendances des conjoints biactifs dans l'accompagnement des enfants
2011
International audience; L'approche des différences de genre dans la mobilité a été renouvelée à partir des années 2000 par l'attention portée aux formes d'interdépendance entre conjoints pour leurs déplacements quotidiens. Dans ce travail mobilisant l'enquête ménages-déplacements d'Île-de-France, nous en avons relevé deux types à partir de l'analyse de l'accompagnement des enfants des conjoints de couples de biactifs. D'une part, il y a un effet d'entraînement. Lorsqu'un conjoint fait de l'accompagnement, l'autre a une probabilité plus forte d'en faire également. D'autre part, les conjoints se distribuent entre eux l'accompagnement avant travail et après travail. Toutefois, l'interdépendanc…
From the great depression to bretton woods: Jacob Viner and international monetary stabilization (1930-1945)
2009
This paper examines Jacob Viner's contribution to the debate and the policy decision-making concerning international monetary policy from the Great Depression to the Bretton Woods agreements. An outstanding member of the so-called 'early Chicago School of Political Economy', Viner was actively engaged in the debate over the causes and cures of the Depression, emphasizing the important role international economic problems played in producing its onset and in reinforcing its duration. During the 1930s Viner was an outspoken supporter of international monetary cooperation, set up to secure exchange rates stability, which he regarded as a paramount factor in restoring business confidence and fo…
