Exploring Azure Active Directory Attack Surface: Enumerating Authentication Methods with Open-Source Intelligence Tools
2022
Azure Active Directory (Azure AD) is Microsoft’s identity and access management service used globally by 90 per cent of Fortune 500 companies and many other organisations. Recent attacks by nation-state adversaries have targeted these organisations by exploiting known attack vectors. In this paper, open-source intelligence (OSINT) is gathered from organisations using Azure AD to explore the current attack surface. OSINT is collected from Fortune 500 companies and top 2000 universities globally. The collected OSINT includes authentication methods used by the organisation and the full name and phone number of the primary technical contact. The findings reveal that most organisations are using…
Bile acid–cysteamine conjugates: Structural properties, gelation, and toxicity evaluation
2011
Abstract Design, synthesis, and characterization of six novel bile acid–cysteamine conjugates together with investigation of their structural studies, gelation properties, and preliminary toxicity evaluation, are reported. Solid state properties of selected compounds were studied by means of X-ray diffraction and 13C CPMAS NMR spectroscopy. N-(2-thioethyl)-3α,7α,12α-trihydroxy-5β-cholan-24-amide was shown to exhibit (pseudo)polymorphism, and a single crystal structure of its non-stoichiometric hydrate is reported herein. Cholyl and dehydrocholyl derivatives bearing three functionalities in their steroidal backbone were shown to undergo self-assembly leading to gelation in certain organic so…
L'ergot dépasse le seigle cet ancien compagnon de l'homme ressort les griffes
2010
National audience; L’ergot du seigle dû à Claviceps purpurea se fait remarquer en cultures de céréales en France depuis 2000, sporadiquement et avec une prévalence moindre qu’en Europe du Nord. Le facteur climatique (4 années favorables de 2000 à 2009 incluses) joue sur cette réémergence, mais aussi des évolutions de pratiques culturales : développement du nonlabour et présence accrue de graminées adventices sensibles dans les parcelles ou à proximité. Les connaissances sur la biologie de C. purpurea et les facteurs le favorisant sont rappelées. Le rôle des graminées adventices et prairiales est évoqué avec les sensibilités diverses des espèces, pouvant influencer le choix de celles à impla…

The use of imidazolium group-containing Bronsted acids for masspectrometric determination of biogenic amines in alcoholic beverages
2017
Darbā ir izstrādāta metode sešu biogēno amīnu masspektrometriskai noteikšanai alkoholiskos dzērienos. Metodes pamatā ir kompleksu veidošanās starp biogēniem amīniem un imidazolija grupu saturošu Brensteda skābi, kas nodrošina ātru un selektīvu analīzi bez parauga sagatavošanas. Darba gaitā ir izpētīta vairāku masspektrometra parametru ietekme uz biogēno amīnu kompleksu rašanos, un izvēlētas specifiskās MRM pārejas. Metodes aprobācijai izvēlēti un analizēti astoņi alkoholiskie dzērieni.
Could halophilic archaea improve the traditional salted anchovies (Engraulis encrasicholus L) safety and quality?
2010
Aims: The positive influence of two selected extremely halophilic archaea strains in the production of salted anchovies (Engraulis encrasicolus, L., 1758) was highlighted. Methods and Results: Anchovies produced with salt artificially contaminated with halophiles exhibited lower loads of staphylococci, Enterobacteriaceae and lactic acid bacteria, and a reduced content of histamine as well as an improved organoleptic acceptance. Conclusions: The findings of this survey are expected to enhance the safety of salted anchovies, with regard to the histamine formation during ripening, and to improve the sensory attributes of this product. Significance and Impact of the Study: This study represents…
Mortality and demographic recovery in early post-black death epidemics: Role of recent emigrants in medieval Dijon
2020
International audience; Objective and methodsWe analyze the influence of population movement on susceptibility to death and resilience during two epidemics occurring in Dijon soon after the Black Death. Using a specific program designed to propose links between entries in annual tax registers, we define tentative heads of household, the elapsed time since their first registration and their ties with other persons within the city.ResultsDuring the 1400 epidemic heads of household who were registered for 1–3 years die in large numbers, whereas during years without epidemics, their death rate is lower than that of heads of household who were registered longer. Recent registration is an epidemi…

Baltic Sea in Estonian and Finnish media : discussed topics and stakeholders
2016
In this paper the stakeholders and most discussed topics of Baltic Sea in the media are examined. Baltic Sea is a fragile ecosystem that provides variety of services to the locals. Not only the locals hold the stake, but also industries and governments. This paper aims to present the complexity of stakeholder network and contradicting interests. Altogether 104 newspaper articles from Estonian and Finnish media on Baltic Sea were used as the data source and the concerning topics, themes and stakeholders were surveyed. The qualitative data was inserted to the textual analysis software QDA Miner 4 Lite. Three main topics were named according to the concept of three pillars of sustainability- e…
The Quest for Raw Materials in the British Paper Trade : The Development of the Bamboo Pulp and Paper Industry in British India up to 1939
2018
The British paper trade history was defined since the mid-1850s by a quest for a new raw material to replace rags. The requirements of the paper trade were first met by a discovery that esparto grass from Spain, and later from North Africa, could be utilised in British mills. Beginning in the late 1870s, the success of using esparto encouraged mill developments in British India. The increased dependence on imported wood pulp, the likelihood of a pulp famine, and the consequent increase in price for imported wood pulp drew attention to the possibility of making commercial volumes of good quality pulp from indigenous Indian grasses. Bamboo began being treated after the First World War, when t…
