Connecting the data landscape of long-term ecological studies: the SPI-Birds data hub
2021
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long-term studies of individually marked animals are not an exception. These studies are especially important as instrumental for understanding evolutionary and eco-logical processes in the wild. Furthermore, their number and global distribution provides a unique opportunity to assess the generality of patterns and to address broad-scale global issues (e.g. climate change).
(Table 1) Age determination of sediment profile SO90-41KL/63KA
2002
The 14C ages of planktonic foraminifers Globigerinoides sacculifer bracketing the Younger Dryas in a d18O record of Globigerinoides ruber from a laminated sediment core on the Pakistani continental margin suggest that surface reservoir ages in the Arabian Sea were in excess of 1000 years during the deglaciation. A least squares error fit of a detailed 14C chronology to the (atmospheric) tree ring record gave variable early Holocene reservoir ages between 780 and 1120 years, well above the prebomb value of 640 years. Mid-Holocene reservoir ages are less well constrained but were probably closer to the prebomb value. The method used to fit individual core sections to the tree ring record was …
Introduction
2014
Nowadays, software engineers face a wide range of particular application domains such as electronic commerce, enterprise resource planning, mobile computing, self-organisation, pervasive and adaptive computing, etc. The resulting heterogeneity and required functionalities call for complex systems and open architectures that may evolve dynamically over time so as to accommodate new components and meet new requirements. This is probably one of the main reasons why the agent metaphor and agent-based computing are gaining momentum in these areas.
Robotic versus laparoscopic sacrocolpopexy for apical prolapse: a case-control study
2016
The apical prolapse has always been considered the most complex of the defects of the pelvic floor, for both the difficulty of the surgical corrective technique and for the high post-surgical recurrence rate. Today, the laparoscopic sacrocolpopexy can be considered the standard treatment for apical prolapse. In the last years, several author performed robotic sacrocolpopexy, obtaining positive results. So, we developed a case-control study in order to compare the surgical outcome of robotic group with a control group of laparoscopic approach in patients with symptomatic apical pro-lapsed between January 2015 and December 2015 at University Hospital Policlinico “P. Giaccone” and Ospedali Riu…
Quantification of Salmonella spp., Listeria monocytogenes and Escherichia coli O157:H7 in non-spiked food products and evaluation of real-time PCR as…
2011
Abstract Escherichia coli O157:H7, Listeria monocytogenes and Salmonella spp. are foodborne pathogens frequently associated with foods such as poultry, ready-to-eat products, fruits and vegetables. PCR-based procedures are rapid, sensitive and accurate; in particular, real-time PCR (qPCR), which besides being an automated high-throughput technique, allows quantification of foodborne pathogens. In the present work, qPCR-based methods were applied for the quantitative detection of E. coli O157:H7, Salmonella spp. and L. monocytogenes in a total of 306 non-spiked food samples in a study carried out in two laboratories simultaneously. qPCR allowed the detection of the three pathogens in around …
An interlaboratory study as useful tool for proficiency testing of chemical oxygen demand measurements using solid substrates and liquid samples with…
2009
In 2008, the first Proficiency Testing Scheme of Chemical Oxygen Demand (1stCOD-PTADG) was conducted to assess the results obtained for different research groups whose field work is mainly anaerobic digestion. This study was performed using four samples, two solid samples as raw materials and two solid samples to prepare high concentration suspended solid solutions. Invitations were sent to a large number of laboratories, mainly to anaerobic digestion research groups. Finally, thirty labs from sixteen countries agreed to participate, but for different reasons four participants could not send any data. In total, twenty-six results were reported to the COD-PT coordinator. This study showed th…
Urban consumers’ attitudes and willingness to pay for functional foods in Iran: A case of dietary sugar
2017
Growing concerns for the incidence of incurable diseases and high costs of health care have attracted consumers to functional foods in the world. These foods are characterized with health improvement, lower risk of disease incidence and less health hazards. The present work examined consumers’ attitude and willingness to pay for dietary sugar in Rasht city, Iran. The studied sample included 125 citizens of Rasht in spring and summer of 2016 whose size was determined by Mitchell and Carson approach. Results of contingent valuation method on the basis of one-and-one-half-bound choice model revealed that the descriptive variable of bid had negative, statistically significant impact on the acce…
(Table 2) Age determination of sediment core NIOP-C2_929
2007
In this study we present a sea surface temperature (SST) record from the western Arabian Sea for the last 20,000 years. We produced centennial-scale d18O and Mg/Ca SST time series of core NIOP929 with focus on the glacial-interglacial transition. The western Arabian Sea is influenced by the seasonal NE and SW monsoon wind systems. Lowest SSTs occur during the SW monsoon season because of upwelling of cold water, and highest SSTs can be found in the low-productivity intermonsoon season. The Mg/Ca-based temperature record reflects the integrated SST of the SW and NE monsoon seasons. The results show a glacial-interglacial SST difference of ~2°C, which is corroborated by findings from other Ar…
Next-Generation Sequencing in Clinical Practice
2019
Abstract During the past few decades, Sanger sequencing represented the “gold standard” technique. In order to better define the mutational status of several genes at the same time, next-generation sequencing methodologies have been introduced in the molecular laboratory workflow. In the era of personalized medicine, this technological improvement plays a key role in the comprehensive molecular characterization of cancer patients in order to get a “tile” target therapy. For different cancer patients, different target therapies are available and different genes serve as clinical it relevant biomarkers. This chapter reviews the principal features of these novel technologies and their applicat…
Mass and energy flux estimates at different spatial resolutions in a heterogeneous area through a distributed energy-water balance model and remote s…
2012
Computed ET with the FEST-EWB model at high spatial resolution 10 m showed for the three days of analysis a mean relative error of 9.4% compared to AHS data, whereas for land surface temperature comparison a relative error of 1.6% was found. Then, LSTs from AHS and FEST-EWB were aggregated at decreasing spatial resolutions 50, 150, 300, 400, 500, 600, 750, and 1000 m, showing that the thermodynamic variability tends to disappear with a lower number of classes in the histograms and with a decrease of the coefficient of variation CV and of standard deviation values. At each scale, a similar behaviour was reported between each pair of images, with the values of standard deviation starting, res…
