The environmental benefits of carsharing: The case study of Palermo

2020

Abstract The problems related to traffic emissions are becoming increasingly pressing and serious, especially in big cities where the private car plays the main role in the mobility of people, being excessively used, while walking, cycling and the use of public transport are often seen as secondary options and are hampered by a poorly urban environment. Therefore, solutions must be found to reduce the number of cars circulating in the city and to support the most sustainable modes of transport at the same time, in order to reduce emissions of greenhouse gases and harmful substances. A modal alternative which is of undoubted interest could be represented by carsharing, which is a mode comple…

Mākslinieciskās izteiksmes līdzekļi vieglo automašīnu reklāmās

2016

Reklāmām ir nepieciešams būt pievilcīgām un pārliecinošām, ņemot vērā, ka to mērķis ir piesaistīt mērķauditorijas uzmanību un pārliecināt iegādāties produktu. Tādējādi par šī bakalaura darba centrālo pētījuma objektu kļūst reklāmu ekspresivitāte, kura tiek sasniegta, izmantojot tekstveida un attēla atveidojuma aspektus. Bakalaura darbā analizē, kā “Volkswagen” vieglo automašīnu drukātās reklāmas ir veidotas no tekstveida un attēla atveidojuma rakursa. Pētījuma korpuss sastāv no 41 drukātās vieglo automašīnu reklāmas, kuras aptver laika periodu 2000.- 2015. gads. Pētījuma teorētiskā bāze ir balstīta uz Leech un Short (1981) un Bergera (2011) raksta un reklāmu analīzes metodēm. Izvēlēto reklā…

Stimulated Raman-Spectroscopy of the Q-Branch of Nitrogen at High Pressure - Collisional Narrowing and Shifting in the 150-6800 Bar Range at Room Tem…

1992

0026-8976; The Raman Q branch of N2 has been recorded at room temperature in the pressure range 150-6800 bar, which corresponds to densities from 135 to 800 amagat. In this domain, the Raman Q branch profile is mainly determined by the well-known collisional narrowing. The experimental data have been obtained by means of a high resolution stimulated Raman spectrometer. The linewidth and line shift of the band have been accurately measured as functions of the density, and their density dependences have been fitted by polynomials. The minimum of the linewidth and the maximum of the red shift have been clearly observed at respectively 735.8 and 532.3 amagat. The lineshape was found to be Loren…

Femtosecond time resolved coherent anti-Stokes Raman spectroscopy: Experiment and modelization of speed memory effects on H2-N2 mixtures in the colli…

2005

194317; With the aim of temperature diagnostic, femtosecond time-resolved CARS (coherent anti-Stokes Raman spectroscopy) is applied to probe H2 in H2-N2 mixtures. In a first part, a Lorentzian profile is used to model the femtosecond CARS response. A difference between the experimental broadening and the expected one is observed in the collision regime. The observed broadening increases strongly in an inhomogeneous way with respect to the perturber concentration. This is of considerable importance for temperature measurements. In a second part, we show that in the collision regime, this inhomogeneous broadening is due to the speed dependence of the collisional parameters and the memory effe…

Domain shuffling between Vip3Aa and Vip3Ca: chimera stability and insecticidal activity against European, American, African, and Asian pests

2020

The bacterium Bacillus thuringiensis produces insecticidal Vip3 proteins during the vegetative growth phase with activity against several lepidopteran pests. To date, three different Vip3 protein families have been identified based on sequence identity: Vip3A, Vip3B, and Vip3C. In this study, we report the construction of chimeras by exchanging domains between Vip3Aa and Vip3Ca, two proteins with marked specificity differences against lepidopteran pests. We found that some domain combinations made proteins insoluble or prone to degradation by trypsin as most abundant insect gut protease. The soluble and trypsin-stable chimeras, along with the parental proteins Vip3Aa and Vip3Ca, were tested…

Cicatrices chéloïdes de la tête et du cou

2012

A keloid scar is a benign proliferative lesion of dermic collagen. It is predominant in black skin patients. It is most commonly located on the head and neck. Skin trauma and a genetic predisposition may be responsible for the keloid scar. Nevertheless, the pathogenesis of keloid scar is still unclear, and no currently available treatment is 100% effective. The authors had for aim to review the current data on keloid scar pathogenesis and treatment for an optimal management of this condition.

Study of Collisional Effects on Band Shapes of the ν1/2ν2 Fermi Dyad in CO2 Gas with Stimulated Raman-Spectroscopy .3. Modeling of Collisional Narrow…

1994

0021-9606; High resolution stimulated Raman spectra (SRS) of the ν1/2ν2 Fermi dyad of CO2 have been recorded in the 0.4-22. amagat density range at 700 K and in the 0.6-16 amagat density range at 900 K. The data have been successfully analyzed with a theoretical model taking into account both rotational line mixing through the energy corrected sudden-polynomial (ECS-P) law for the relaxation matrix and vibrational line broadening gamma(v) and line shifting delta(v). The two vibrational parameters have been accurately determined from fit to the experimental spectra. These new high temperature data together with previous data obtained at 295 and 500 K [B. Lavorel et al., J. Chem. Phys. 93, 21…

Long-term outcome of ventral buccal mucosa onlay graft urethroplasty for urethral stricture repair

2004

Abstract Objectives To evaluate our patients who were treated with ventral buccal mucosa onlay grafts for open urethral stricture repair with a follow-up exceeding 5 years. Buccal mucosa onlay is widely used for urethral reconstruction; however, the long-term outcome of these patients remains unclear. Methods During the past 10 years, 67 patients underwent ventral buccal mucosa onlay graft surgery for urethral stricture repair. Of these, 32 were followed up for longer than 5 years (mean 6.9 years) for the occurrence and timing of any postoperative complications. All patients had undergone prior internal urethrotomy (mean 2.9 procedures), and the average length of the stricture was 4.3 cm (r…

Klebsiella oxitoca folliculitis mimicking tinea barbae in a diabetic man

2005

A 55-year-old male dairy farmer was admitted to our hospital with a skin infection on the neck and face. He was apparently in good general health, and his medical history was unremarkable. He reported that, 50 days before admission, a pruritic red maculopapular rash had developed on the anterior region of his neck. This rash failed to improve after a 10-day course of trimethoprim-sufamethoxazole and fluconazole; rather it progressively worsened. On admission, examination revealed confluent follicular papulae-pustules with purulent-hematic exudation and crusting, on an erythematous-edematous area extending over the anterior region of the neck, chin and mandible (Fig. 1); hairs within the aff…
