Tropical Temperate Toughs over southern Africa: mechanisms and evolution in response to climate change

2015

In the Southern Hemisphere, Southern Africa and the south-west Indian Ocean are one of the three preferred regions where interactions between the tropics and midlatitudes develop. This is the South Indian Convergence Zone (SICZ), where northwest-southeast oriented cloud bands form at the synoptic scale (between 3 and 5 days). These bands are mainly found during the austral summer and are commonly referred to as tropical temperate troughs (TTTs). This research aims at improving our knowledge related to TTTs, with a study on the dynamics associated with these systems, and an analysis of their possible evolution during the 21st century.The first part of this thesis aims at identifying favorab…

Evolution of dry season low cloud cover over the Atlantic coast of Central Africa from diurnal to interannual scale

2022

Despite its bioclimatic importance, few studies have focused on the stratiform low-level cloud cover ofthe dry season (June-September) of the Atlantic coast of Central Africa. Using in-situ data documenting theperiod 1971-2019, we show that this cloud cover is underestimated by SAFNWC satellite observations andCMIP6 models. We identify three types of days: clear, cloudy at night and totally cloudy, the latterbeing more frequent on the coast and inland, to the windward of the Cristal and Chaillu Mountains. Onan interannual scale, temperature anomalies in the South Tropical Atlantic, the equatorial Pacific and theCongo Basin, by modulating the meridional and zonal circulation cells, influence…

Reciprocal influence of B cells and tumor macro and microenvironments in the ApcMin/+ model of colorectal cancer

2017

One of the most fascinating aspects of the immune system is its dynamism, meant as the ability to change and readapt according to the organism needs. Following an insult, we assist to the spontaneous organization of different immune cells which cooperate, locally and at distance, to build up an appropriate response. Throughout tumor progression, adaptations within the systemic tumor environment, or macroenvironment, result in the promotion of tumor growth, tumor invasion and metastasis to distal organs, but also to dramatic changes in the activity and composition of the immune system. In this work, we show the changes of the B-cell arm of the immune system following tumor progression in the…

Data from: Key roles for freshwater Actinobacteria revealed by deep metagenomic sequencing

2014

Freshwaters ecosystems are critical but fragile environments directly affecting society and its welfare. However, our understanding of genuinely freshwater microbial communities, constrained by our capacity to manipulate its prokaryotic participants in axenic cultures, remains very rudimentary. Even the most abundant components, freshwater Actinobacteria, remain largely unknown. Here, applying deep metagenomic sequencing to the microbial community of a freshwater reservoir, we were able to circumvent this traditional bottleneck and reconstruct de novo seven distinct streamlined actinobacterial genomes. These genomes represent three new groups of photoheterotrophic, planktonic Actinobacteria…

Mājturības kultūra Latvijā: Kaucmindes Mājturības semināra piemērs

2015

Mājturības vēsture kā sociālās vēstures virziens līdz šim nav saistījusi Latvijas vēsturnieku uzmanību, līdz ar to veiktais pētījums „Mājturības kultūra Latvijā: Kaucmindes Mājturības semināra piemērs” ir oriģināla novitāte Latvijas vēstures zinātnē. Vienlaikus tēma līdzsvaro mūsdienās aktuālo dzimtes studiju virzienu. Maģistra darbā sniegts vispārējs ieskats mājturības kultūras attīstībā Latvijā 20. gs. 20. – 30. gados, analizējot Kaucmindes Mājturības semināra (kopš 1938. gada Latvijas Mājturības institūts) darbu. Pētījumā aplūkojamā izglītības iestāde sagatavoja augstākās kvalifikācijas speciālistes mājturības nozarē, kas darbojās gan kā praktiskas mājsaimnieces, gan iesaistījās mājturīb…

Last millennium northern hemisphere summer temperatures from tree rings: Part I: The long term context

2016

Текст статьи не публикуется в открытом доступе в соответствии с политикой журнала. Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have been progressively improved over the last 20 years as new datasets have been developed. This paper, and its companion (Part II, Anchukaitis et al. in prep), details the latest tree-ring (TR) based NH land air temperature reconstruction from a temporal and spatial perspective. This work is the first product of a consortium called N-TREND (Northern Hemisphere Tree-Ring Network Development) which brings together dendroclimatologists to identify a collective strategy for improving large-scale summer temperature reconstructions…

Mobile phones, identity and discursive intimacy

2005

This paper deals with the sociocultural effects of mobile phones in Philippine society. In particular it looks at how mobile phones have affected notions of identity and the rise of the sexual subject. It also deals with the political possibilities and implication of this new communicative technology in a society with previously poorly developed telephonic and other communicative technologies. Mobile phones allow absent subjects to exercise a daily presence in their communities of origin. This absent presence generates virtual subjects interacting primarily via the mobile phone.
