The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes

2003

Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…

Redrawing as key to the spatial thought of Hana Kučerová Zaveská

2017

The paper analyzes two works of Hana Kučerová Zaveská, Czech architect and designer who has made an important contribution to the Modern Movement, dealing with social housing and social services and placing its emphasis on improving the status of women. His brief but intense activity is developed in Czechoslovakia in the period between the wars and is influenced by the architecture and art movements that occurred in the country during the twenties and thirties. In the footsteps of Marcel Breuer and Mies van der Rohe, she creates furniture where functionality is combined with the elegance and in which we recognize the signature style of the designer, her innovative use of materials and produ…

The Warriors' Cult : representations of masculinity on the subreddit /r/TheRedPill

2018

Internet on yksi arkemme merkittävimmistä informaation lähteistä ja kantaa sisällään paljon mielenkiintoista sisältöä. Reddit on moniaiheinen internet- ja keskustelusivusto, jonka yksi kiehtovimmista yhteisöistä (subredditeistä) on /r/TheRedPill. Yhteisö kuvailee itseään seuraavasti: “The Red Pill: Keskustelua seksuaalisesta strategiasta kulttuurissa, jossa on vähenevissä määrin positiivisia identiteettejä miehille”. Vuosien 2017 ja 2018 aikana mediassa on keskusteltu paljon miehistä ja huomattavan usein heitä on kritisoitu esimerkiksi epäsopivasta seksuaalikäyttäytymisestä. Halusin omassa tutkimuksessani sukeltaa sisälle yhteisöön, joka pyrkii voimaannuttamaan miehiä yhteiskunnallisen kesk…

Predicción del parto prematuro en reproducción asistida : la importancia del cérvix

2014

Introducción El parto pretermino es aquel que acontece antes de la semana 37 y después de la semana 23 de gestación. A pesar de los avances de medicina perinatal no se ha conseguido disminuir esa cifra, es más, se ha producido un aumento en países desarrollados, gracias al incremento de las técnicas de reproducción asistida que generan un aumento de las gestaciones múltiples pero también gestaciones únicas de mayor riesgo. La patogénesis del parto pretérmino es aún discutida, y no está claro si representa una activación temprana e idiopática del trabajo de parto normal o es el resultado de algún mecanismo patológico. La detección y el intento de predicción del parto dependen de la identific…

A methodology for the control of the residual lifetimes of carbon fibre reinforced composite pressure vessels

2005

International audience; Pressure vessels must be periodically proof tested. Traditional techniques for metal vessels are inapplicable for composite vessels as the latter do not break by crack propagation so that the reasoning behind the traditional testing procedures is not appropriate. Damage accumulation leading to the degradation of a composite vessel is by fibre failure. Fibres show a wide distribution in strengths and loading a composite inevitably breaks some. The method which has been developed is supported by an analysis of delayed fibre failure due to the relaxation of the resin around fibre breaks. This provokes overloading of intact fibres neighbouring breaks. The time until a cr…

Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes

2015

Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…

The changing paradigm of document delivery : exploring researchers’ peer to peer practices

2016

Purpose By definition, interlibrary lending is a process involving two libraries. The digital revolution changed the method by which the scientific documents were disseminated during the past couple of decades. Nowadays, researchers can exploit several software applications that enable them to upload, save and deliver their documents from one peer to another without the need for a middle man. This paper reviews this change via a study conducted in two Finnish academic universities. The aim of this study was to determine the extent to which researchers have adopted these new possibilities for document dissemination and how this change will affect the role of the libraries in document delive…

Efficiency of COVID-19 Testing Centers in Iran: A Data Envelopment Analysis Approach

2022

AbstractObjective:The purpose of this study is to investigate the efficiency of the Iranian Red Crescent Society (IRCS) in managing their nonmonetary resources involved in coronavirus disease 2019 (COVID-19) response.Methods:For this purpose, the data envelopment analysis approach was used to measure the efficiency, considering the number of personnel and vehicles and screened passengers as the input and output parameters, respectively. It was examined the efficiency of 10 IRCS’s branches given 17 d of screening operation. For the analysis, the DEA SolverPro software 15a version was used.Results:The results show that only 1 branch had been fully efficient in using the resources, while 5 bra…
