Pleistocene sea-floor fibrous crusts and spherulites in the Danakil Depression (Afar, Ethiopia)

Jaramillo‐Vogel, David ; Foubert, Anneleen ; Braga, Juan Carlos ; Schaegis, Jean‐Charles ; Atnafu, Balemwal ; Grobéty, Bernard ; Kidane, Tesfaye

In: Sedimentology, 2019, vol. 66, no. 2, p. 480–512

Pleistocene fibrous aragonite fabrics, including crusts and spherules, occur in the Danakil Depression (Afar, Ethiopia) following the deposition of two distinctive Middle and Late Pleistocene coralgal reef units and pre‐dating the precipitation of evaporites. Crusts on top of the oldest reef unit (Marine Isotope Stage 7) cover and fill cavities within a red algal framework. The younger...

Excitonic channels from bio-inspired templated supramolecular assembly of J-aggregate nanowires

Anantharaman, Surendra B. ; Messmer, Daniel ; Sadeghpour, Amin ; Salentinig, Stefan ; Nüescha, Frank ; Heier, Jakob

In: Nanoscale, 2019, vol. 11, no. 14, p. 6929–6938

Supramolecular assemblies with controlled morphology are of paramount importance for energy transport in organic semiconductors. Despite considerable freedom in molecular design, the preparation of dyes that form one dimensional J-aggregates is challenging. Here, we demonstrate a simple and effective route to functionalize dendronized polymers (DPs) with J-aggregates to construct tubular...

Deciphering the complexity of human noncoding promoter-proximal transcriptome : different scales of transcriptional control : from a single gene to the whole epigenome

Mapelli, Sarah Natalia ; Krause, Rolf (Dir.) ; Catapano, Carlo V. (Codir.)

Thèse de doctorat : Università della Svizzera italiana, 2019 ; 2019INFO001.

Long noncoding RNAs (lncRNAs) have gained increasing interest in molecular studies, their active participation in important biological functions has emerged and their direct involvement in genomic reprogramming during development and diseases, including cancer, has been demonstrated. Several studies have shown their active contribution in transcriptional control and they are emerging as...

Hydrogeological and topographical controls on catchment dynamics and their implications for low flows

Carlier, Claire ; Brunner, Philip (Dir.) ; Hunkeler, Daniel (Codir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Periods with scarce precipitation will likely occur more frequently and last longer under changing climatic conditions, even in relatively humid regions like Switzerland. To assess the sensitivity of water resources to dry spells and to identify regions that might experience water scarcity issues, a thorough understanding of the mechanisms governing catchment dynamics in the absence of rain is...

From Asia to Europe : evaluation of parasitoids for the biological control of the invasive fruit pest "Drosophila suzukii"

Girod, Pierre ; Turlings, Ted (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2018.

Agricultural processes are constantly improved to improve crop yields. However, 40% of crop productions are currently lost to pests each year. Insect pests are one of the main factors of these losses and their management is one of the top priorities that researchers are facing worldwide. An important part of these losses are caused by pest with alien origins. Globalization and climate change...

Size and shape: the developmental regulation of static allometry in insects

Shingleton, Alexander W. ; Frankino, W. Anthony ; Flatt, Thomas ; Nijhout, H. Frederik ; Emlen, Douglas J.

In: BioEssays, 2007, vol. 29, no. 6, p. 536-548

Among all organisms, the size of each body part or organ scales with overall body size, a phenomenon called allometry. The study of shape and form has attracted enormous interest from biologists, but the genetic, developmental and physiological mechanisms that control allometry and the proportional growth of parts have remained elusive. Recent progress in our understanding of body‐size...

Long-term effects of deep-seated landslides on transportation infrastructure : a case study from the Swiss Jura Mountains

Preisig, Giona

In: Quarterly Journal of Engineering Geology and Hydrogeology, 2018, vol. 2017, p. 128-137

Deep-seated landslides (DSLs) involve large-scale deformation and likely affect transportation infrastructure. Movement rates are in general very slow (less than a metre per year) with acceleration periods controlled by external factors such as the seasonal fluctuation of groundwater pressure. Acceleration response may change from season to season depending on hydrogeological conditions, changes...

Al confine di Chiasso : regards sur l'évolution du travail du Corps des gardes-frontière tessinois et son impact sur le contrôle migratoire

Lacarbonara, Nicole ; Piguet, Etienne (Dir.)

Mémoire de master : Université de Neuchâtel, 2019.

Ce mémoire de master analyse l’évolution du travail des gardes-frontière à la frontière de la zone de Mendrisio (Tessin) des années 1990 à ce jour. Plus particulièrement, il s’agit d’étudier l’évolution des tâches et leurs applications par l’examen du discours et des souvenirs des gardes-frontière qui ont partagé avec moi leur expérience de terrain. Après avoir...

Essays on the globalization of firm ownership

Zhang, Xiqian ; Salva, Carolina (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2017 ; 2671.

This dissertation is constituted of three distinct chapters. The first chapter seeks to resolve a recent debate on whether sovereign wealth funds(SWFs) have non-financial objectives and politically distort firm performance. I find that, once stake size is considered, previous belief that SWFs would affect firm performance should be reformulated. SWFs rarely seek an influential stake in listed...

Des abeilles, des ruches et des humains : les Centres apicoles : des acteurs de la réalisation de la filière apicole au Burkina Faso

Boila, Zeno ; Fresia, Marion (Dir.) ; Aebi, Alexandre (Codir.)

Mémoire de master : Université de Neuchâtel, 2018 ; NET 900/431.

La présente étude se focalise sur les processus de structuration de la filière apicole au Burkina Faso et sur le rôle joué par les Centres apicoles ; des structures nées en tant qu’unités de transformation des premiers projets de développement en apiculture élaborés par certaines ONG étrangères durant la fin des années 1990 et le début des années 2000. En partant du constat...
