The architectural patronage of the FÄáčimid queen-mother DurzÄn (d. 385/995): an interdisciplinary analysis of literary sources, material evidence and historical context
This paper on FÄáčimid female architectural patronage is divided into two parts. The first contains an analysis of the link between historical sources and epigraphic evidence, the second interprets such evidence in the light of the political and economic climates in which such patronage took place. The figure this paper focuses on is DurzÄn. She was the consort of the FÄáčimid imam-caliph al-Muâizz (r. 341-365/953-975) and mother of his successor, the imam-caliph al-âAzÄ«z (r. 365-386/975-996) and the first and most prolific of the FÄáčimid patronesses
Design of the traction battery for a Formula SAE racing car
This paper describes the design of the traction battery for the new electric Formula SAE vehicle of the University of Pisa. A model based design methodology extended to the mechanical, electrical and thermal domains was applied to find the best trade-off between the battery weight and the maximum power available at the wheel. The designed battery configuration was validated by means of electrical and thermal simulations
Gene Flow in Medicago Through Somatic Hybridization
The objective of this research was the characterization at both molecular and phenotypic level of three somatic hybrid plants obtained by electrofusion of protoplasts of Medicago sativa with those of M.coerulea, M.falcata and M.arborea, three Medicago species in a different relation with alfalfa. Different kinds of rearrangements including the amplification of new spacer-length variants were detected at rDNA loci in the somatic hybrids. Analysis of field performances confirmed the suitability of these plants for breeding purposes
Characterization of prevalence and genetic subtypes of Blastocystis sp. in wild and domestic Suidae of central Italy aided by amplicon NGS
Blastocystis spp. is a common single-celled intestinal symbiont, comprising several genetic subtypes (ST) and trans-
missible by animal-to-animal, human-to-human, animal-to-human and, possibly, human-to-animal routes. This work
was designed to explore the presence of Blastocystis in sympatric domestic and wild suids and their ability to carry
zoonotic STs, in a condition of widespread opportunity to come in contact with the microorganism through their
shared water and food resources, and other carriers. We sampled 42 and 37 stool samples from wild boars and
domestic pigs, respectively. STs were first identified by PCR followed by Sanger sequencing. Sequences represented in
double-band PCR products or in Sanger chromatograms displaying multiple peaks, were resolved by next generation
sequencing (NGS). Twenty-six (61.9%) wild boar and 26 (70.2%) pig samples were PCR-positive, respectively. ST3,
ST5 and ST15 were found in 3.8%, 38.4% and 80.8% of the positive wild boars and 11.5%, 88.5%, 11.5% of the
positive pigs, respectively. ST1 was found only in pigs (3.8%). STs 5 and 15 were common in both groups of animals,
but in reversed proportions, suggesting preferential colonization. We found significantly different ST distributions
among wild boars and domestic pigs. This might indicate that lifestyle differences between the two populations
influence their risk for contracting certain subtypes, or that ST5 and ST15 can colonize preferentially wild or domestic
animals. Based on the STs described here, wild boars and domestic pigs can act as reservoirs with zoonotic potential.
The ability of suids to carry zoonotic STs appears to be higher when using NGS than Sanger sequencing, and resolution
of complex sequencing profiles is imperative before excluding the presence of STs of human concern
Publication and patent analysis of European researchers in the field of production technology and manufacturing systems
This paper develops a structured comparison among a sample of European researchers in the field of Production Technology and Manufacturing Systems, on the basis of scientific publications and patents. Researchers are evaluated and compared by a variegated set of indicators concerning (1) the output of individual researchers and (2) that of groups of researchers from the same country. While not claiming to be exhaustive, the results of this preliminary study provide a rough indication of the publishing and patenting activity of researchers in the field of interest, identifying (dis)similarities between different countries. Of particular interest is a proposal for aggregating analysis results by means of maps based on publication and patent indicators. A large amount of empirical data are presented and discusse
SuperB: a linear high-luminosity B Factory
This paper is based on the outcome of the activity that has taken place
during the recent workshop on "SuperB in Italy" held in Frascati on November
11-12, 2005. The workshop was opened by a theoretical introduction of Marco
Ciuchini and was structured in two working groups. One focused on the machine
and the other on the detector and experimental issues.
The present status on CP is mainly based on the results achieved by BaBar and
Belle. Estabilishment of the indirect CP violation in B sector in 2001 and of
the direct CP violation in 2004 thanks to the success of PEP-II and KEKB e+e-
asymmetric B Factories operating at the center of mass energy corresponding to
the mass of the Y(4s). With the two B Factories taking data, the Unitarity
Triangle is now beginning to be overconstrained by improving the measurements
of the sides and now also of the angles alpha, and gamma. We are also in
presence of the very intriguing results about the measurements of sin(2 beta)
in the time dependent analysis of decay channels via penguin loops, where b -->
s sbar s and b --> s dbar d. Tau physics, in particular LFV search, as well as
charm and ISR physics are important parts of the scientific program of a SuperB
Factory. The physics case together with possible scenarios for the high
luminosity SuperB Factory based on the concepts of the Linear Collider and the
related experimental issues are discussed.Comment: 22 pages, 22 figures, INFN Roadmap Repor

Research Output From University-Industry Collaborative Projects
We study collaborative and noncollaborative projects that are supported by government grants. First, we propose a theoretical framework to analyze optimal decisions in these projects. Second, we test our hypotheses with a unique data set containing academic publications and research funds for all academics at the major university engineering departments in the United Kingdom. We find that the type of the project (measured by its level of appliedness) increases the type of both the university and firm partners. Also, the quality of the project (number and impact of the publications) increases with the quality of the researcher and firm, and with the affinity in the partners' preferences. The collaboration with firms increases the quality of the project only when the firms' characteristics make them valuable partners
OeBAS and CYP716C67 catalyze the biosynthesis of health-beneficial triterpenoids in olive (Olea europaea) fruits
center dot The bioactive properties of olive (Olea europaea) fruits and olive oil are largely attributed to terpenoid compounds, including diverse triterpenoids such as oleanolic, maslinic and ursolic acids, erythrodiol, and uvaol. They have applications in the agri-food, cosmetics, and pharmaceutical industries. Some key steps involved in the biosynthesis of these compounds are still unknown.center dot Genome mining, biochemical analysis, and trait association studies have been used to identify major gene candidates controlling triterpenoid content of olive fruits.center dot Here, we identify and functionally characterize an oxidosqualene cyclase (OeBAS) required for the production of the major triterpene scaffold beta-amyrin, the precursor of erythrodiol, oleanolic and maslinic acids, and a cytochrome P450 (CYP716C67) that mediates 2 alpha oxidation of the oleanane- and ursane-type triterpene scaffolds to produce maslinic and corosolic acids, respectively. To confirm the enzymatic functions of the entire pathway, we have reconstituted the olive biosynthetic pathway for oleanane- and ursane-type triterpenoids in the heterologous host, Nicotiana benthamiana. Finally, we have identified genetic markers associated with oleanolic and maslinic acid fruit content on the chromosomes carrying the OeBAS and CYP716C67 genes.center dot Our results shed light on the biosynthesis of olive triterpenoids and provide new gene targets for germplasm screening and breeding for high triterpenoid content
