Tephritidae fruit flies are among the most damaging pests of fruit crops worldwide Ceratitis capitata Wiedemann, for instance, can infest more than 250 fruit and vegetable crop species, and constitutes the main phytosanitary restrict for export purposes. The investigation was carried out in a SENASA’s Production Center of Sterile Fruit Flies and PIMU’s laboratory; it was supervised by an OIEA’s irradiation expert. This research comprised two stages: 1) Determine the minimum irradiation dose to avoid emergence of fruit fly adults (bioassay test), and 2) Evaluate 30 000 individuals having been exposed to the minimum effective dose to provide statistically reliable data (confirmatory test). It was confirmed that no adult emergence occurred at 0,1 kGy, and no significant differences were found between treated and non-treated mangoes when both chemical and organoleptic tests were applie...

PURPOSEMultiple myeloma (MM) is a highly heterogeneous, incurable disease most frequently diagnosed in the elderly. Therefore, data on clinical characteristics and outcomes in the very young population are scarce.PATIENTS AND METHODSWe analyzed clinical characteristics, response to treatment, and survival in 103 patients with newly diagnosed MM age 40 years or younger compared with 256 patients age 41-50 years and 957 patients age 51 years or older.RESULTSThere were no statistical differences in sex, isotype, International Scoring System, renal involvement, hypercalcemia, anemia, dialysis, bony lesions, extramedullary disease, and lactate dehydrogenase (LDH). The most used regimen in young patients was cyclophosphamide, bortezomib, dexamethasone, followed by cyclophosphamide, thalidomide, dexamethasone and bortezomib, thalidomide, dexamethasone. Of the patients age 40 years or younger, o...

Beams of neutrinos have been proposed as a vehicle for communications under unusual circumstances, such as direct point-to-point global communication, communication with submarines, secure communications and interstellar communication. We report on the performance of a low-rate communications link established using the NuMI beam line and the MINERvA detector at Fermilab. The link achieved a decoded data rate of 0.1 bits/sec with a bit error rate of 1% over a distance of 1.035 km, including 240 m of earth.

The skin is the largest organ of the body that protects it from the external environment. High- frequency ultra sound (HF-US) has been used to visualize the skin in depth and to diagnose some pathologies in dermatological applications. Quantitative ultrasound (QUS) includes several techniques that provide values of particular physical properties. In this thesis work, three QUS parameters are explained and used to characterize healthy skin through HF-US: attenuation coefficient slope (ACS), backscatter coefficient (BSC) and shear wave speed (SWS). They were estimated with the regularized spectral-log difference (RSLD) method, the reference phan- tom method, and the crawling wave sonoelastography method, respectively. All the three parameters were assessed in phantoms, ex vivo and in vivo skin. In calibrated phantoms, RSLD showed a reduc- tion of up to 93% of the standard deviation concern...
