The reactivity of neonatal rabbits to the mammary pheromone as a probe for viability
2012
International audience; Newborn rabbits depend on a daily nursing interaction with the mother to gain milk and to survive. During this interaction, they localise and seize the nipples displaying a typical behaviour triggered by maternal odour cues. The mammary pheromone constitutes such a signal in domestic rabbits: it elicits sucking-related movements in more than 90% of the pups. However, some newborns remain unresponsive to the presentation of the pheromone, even pups apparently healthy and highly motivated to suck. The main goal of the present study was therefore to explore the link between the unresponsiveness of rabbit pups to the mammary pheromone and their growth and survival in bre…
Incidence de la clarification des moûts de raisin sur les fermentescibilltés alcoolique et malolactique
1993
<p style="text-align: justify;">Des essais de débourbage en vinification en blanc, réalisés de 1988 à 1992, mettent en évidence le rôle important joué par la teneur en macromolécules solubles dans le moût de raisin. Les moûts de faible turbidité conduisent en effet à des fermentations alcooliques lentes en relation avec de faibles populations levuriennes. Il est également confirmé que la libération de polysaccharides exocellulaires par les levures au cours de la fermentation alcoolique est d'autant plus élevée que le moût de départ a été fortement appauvri en colloïdes de raisin. Par contre, ce sont dans les lots les plus clarifiés que l'on observe la meilleure fermentescibilité malol…
Keisarinasema ennen ja nyt : Lappeenrannan vanhan rautatieaseman merkitykset paikallisessa kontekstissa 1885-2017
2017
Tutkielma käsittelee tapausesimerkkinä Lappeenrannan entisen rautatieaseman merkityksiä sen elinkaaren 1885–2013 aikana ja edelleen nykyhetkenä, jolloin rakennusta ei enää ole. ”Vanhaksi asemaksi” ja myöhemmin ”Keisarinasemaksi” kutsutulla rakennuksella oli monivaiheinen historia, kunnes se vasta restauroituna katosi kaupunkikuvasta tulipalon seurauksena vuonna 2013. Tässä työssä tarkastellaan rakennuksen ja sen käyttäjien suhteen muuttumista, rakennuksen identiteetin muuttumista ja merkityksiä, joita rakennukseen on kohdistettu eri aikoina. Asemarakennus rakennettiin 1885 kun Lappeenrantaan valmistui Simolasta johtava haararata, joka mahdollisti entistä paremmat liikenneväylät kaupunkiin j…
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
Topological canal foliations
2019
Regular canal surfaces of $\mathbb{R}^3$ or $\mathbb{S}^3$ admit foliations by circles: the characteristic circles of the envelope. In order to build a foliation of $\mathbb{S}^3$ with leaves being canal surfaces, one has to relax the condition “canal” a little (“weak canal condition”) in order to accept isolated umbilics. Here, we define a topological condition which generalizes this “weak canal” condition imposed on leaves, and classify the foliations of compact orientable 3-manifolds we can obtain this way.

STUDY CONCERNING FOREST ECOLOGIC RECONSTRUCTIUON ON DEGRADED LAND IN RANGE OCOLUL SILVIC “VALEA CIBINULUI”, SALISTE, ROMANIA
2014
The study examines the stationary conditions, determine solutions to improve degraded land, assessing the cost of ecological restoration work needed in the area of improving degraded lands at Rapa - Copăcel, estimated benefits of the project and its viability. Objectives of the paper: need to introduce in the circuit of productive forest lands within the improvement of the area "La Rapa - Copăcel" danger zone where activation of the phenomena of degradation (erosion , landslides ) predominate. Out of 102.33 ha as area for improvement, the effective area of 101.6 ha is forested, representing a difference of 0.73 ha, 1.2 m wide strip that is to be the place for hedges. Viability of the projec…
THE ATTITUDE AND MOTIVATION OF BUYERS OF TRADITIONAL/ LOCAL/ BIO PRODUCTS IN THE CONTEXT OF AGROTOURISM, IN SIBIU COUNTY, ROMANIA
2013
Based on the statistical data concerning the sheep breeding in district Sibiu and on the information obtained by making investigations markets and fairs where they sell traditional/bio products, the extent was appreciated to which this products are known and desired. The survey was conducted between May and November 2012 in four locations: “Transilvania Peasant Market (Piata Taraneasca Transilvania)”, “Traditional agro-food products Fear (Targul de Produse Agroalimentare Traditionale)” from Huet Market, “Traditional Products and Handicrafts Fear (Targul de Produse Traditionale si Mestesugaresti)” inside the Carrefour hypermarket and in “Agricultural Market” Rasinari, Sibiu county. There wer…

Towards the development of cultural resources of the territory of Agrigento
2011
Agrigento costituisce una delle realtà nazionali più problematiche in cui si materializzano i contrasti più stridenti: l’eccezionale patrimonio archeologico e paesaggistico della Valle dei Templi e un abusivismo edilizio diffuso e multiforme; la bellezza e il degrado del centro storico assediato da volumi edilizi di altezze spropositate; l'eleganza dell’espansione ottocentesca e lo sviluppo di periferie miserabili; opere viarie invasive che non assicurano efficaci collegamenti. Sul territorio in declivio che guarda il mare, si trova il Parco Archeologico e Paesaggistico della Valle dei Templi, sintesi sublime di archeologia e paesaggio agrario ma sfregiato in molte zone da varie tipologie d…
