Isolation of the Bacillus thuringiensis plasmid carrying Bacthuricin F4 coding genes and evidence of its conjugative transfer
( The Journal of Infection in Developing Countries , 2014 , Article)INTRODUCTION: Conjugation is an excellent natural mode of DNA transfer in vivo between bacteria, particularly when these conjugative elements carry technological traits such as bacteriocin encoding genes. In the present ... -
Isolation, differentiation and biodiversity of ureolytic bacteria of Qatari soil and their potential in microbially induced calcite precipitation (MICP) for soil stabilization
( Royal Society of Chemistry , 2018 , Article)Biomineralization plays a key role in modifying the geological properties of soil, thereby stabilizing it against wind erosion, especially in areas characterized by harsh weather and harsh soil (calcareous and arid); i.e. ... -
Isolation, screening and activity of hydrocarbon-degrading bacteria from harsh soils
( Avestia Publishing , 2016 , Conference Paper)The study of microbial communities in relation to their ecology, interaction, and genetics must be covered in Qatar with special soil, weather and water. Microorganisms of an environment never having been exposed to such ... -
Isomorphic Hilbert spaces associated with different complex contours of the PT-symmetric (-x^4) theory
( World Scientific Publishing Co. , 2014 , Article)In this work, we stress the existence of isomorphisms which map complex contours from the upper half to contours in the lower half of the complex plane. The metric operator is found to depend on the chosen contour but the ... -
Isoperimetric properties of condenser capacity
( Elsevier , 2021 , Article)For compact subsets E of the unit disk D we study the capacity of the condenser (D,E) by means of set functionals defined in terms of hyperbolic geometry. In particular, we study experimentally the case of a hyperbolic ... -
It's just not cricket: what we can learn about Qatar's sports strategy by comparing the FIFA World Cup with other mass-participation sports
( Gulf Studies center - College of Arts & Sciences - Qatar University , 2022 , Conference Paper)This paper sheds new light on the motivations and expectations of Qatar's hosting of FIFA 2022 Men's World Cup by comparing football with another popular sport in the country: cricket. In order to understand the particularities ... -
Iterative approximation of common attractive points of further generalized hybrid mappings
( SpringerInternationalPublishing , 2018 , Article)Our purpose in this paper is (i) to introduce the concept of further generalized hybrid mappings, (ii) to introduce the concept of common attractive points (CAP), and (iii) to write and use Picard-Mann iterative process ... -
Iterative scheme for an elliptic non-local free boundary problem
( Taylor & Francis , 2016 , Article)In this paper we treat a non-local free boundary problem arising in financial bubbles, where the model is set in the framework of viscosity solutions. We suggest an iterative scheme which consists of a sequence of obstacle ... -
Jacques-Marie-Jérôme Michau de Montaran , Rapport sur le commerce au Levant (1753)
( Les Éditions Isis , 2022 , Book)La naissance de la diplomatie moderne au XVIe siècle a permis aux chancelleries naissantes de s’informer d’une manière plus directe sur les pays hôtes. En effet, la centralisation accrue des États et des ministères des ... -
Jellyfish diversity, trends and patterns in Southwestern Mediterranean Sea: a citizen science and field monitoring alliance
( Oxford University Press , 2022 , Article)Jellyfish (Cnidaria and Ctenophora) are an essential component of marine ecosystems and represent a potential effect, positive or negative, for several economic activities. Jellyfish blooms and non-indigenous species (NIS) ... -
Jerusalem as a place of exile during the mamluk era
( Academy of Islamic Studies, Dept of Islamic History and Civilization, University of Malaya , 2019 , Article)Jerusalem fell to the Mamluks in the year ce 1260. Up until then the Ayyubids had been ruling the holy city ever since Salah al-Din had liberated it from the Crusaders in ce 1187. Under Mamluk rule, which lasted for nearly ... -
Joint spatial time-series epidemiological analysis of malaria and cutaneous leishmaniasis infection
( Cambridge University Press , 2017 , Article)Malaria and leishmaniasis are among the two most important health problems of many developing countries especially in the Middle East and North Africa. It is common for vector-borne infectious diseases to have similar ... -
Journalism and the Islamic Worldview: Journalistic roles in Muslim-majority countries
( Routledge , 2017 , Article)This paper looks at the extent to which journalistic culture in Muslim-majority countries is shaped by a distinctive Islamic worldview. We identified four principles of an Islamic perspective to journalism: truth and ... -
K-shell photoionization of O+ and O2+ ions: Experiment and theory
( American Physical Society , 2015 , Article)Absolute cross sections for the single and double K-shell photoionization of carbon like O2+ and nitrogen like O+ ions were measured in the 526–620-eV photon energy range by employing the ion-photon merged-beam technique ... -
KERTAS: dataset for automatic dating of ancient Arabic manuscripts
( Springer Verlag , 2018 , Article)The age of a historical manuscript can be an invaluable source of information for paleographers and historians. The process of automatic manuscript age detection has inherent complexities, which are compounded by the lack ... -
