Enabling Green Crowdsourced Social Delivery Networks in Urban Communities.

With the ever-increasing popularity of wearable devices, data on the time and location of popular walking, running, and bicycling routes is expansive and growing rapidly. These data are currently used primarily for route discovery and mobile context awareness, as it provides precise and updated information about urban dynamics. We leverage these data to build ad hoc transportation flows, and we present a novel model that creates delivery networks from these zero-emission transportation flows.

Performance evaluation of hybrid crowdsensing systems with stateful CrowdSenSim 2.0 simulator.

Mobile crowdsensing (MCS) has become a popular paradigm for data collection in urban environments. In MCS systems, a crowd supplies sensing information for monitoring phenomena through mobile devices. Depending on the degree of involvement of users, MCS systems can be participatory, opportunistic or hybrid, which combines strengths of above approaches.

Survey on Urinary Levels of Aflatoxins in Professionally Exposed Workers.

Feed mill workers may handle or process maize contaminated with aflatoxins (AFs). This condition may lead to an unacceptable intake of toxins deriving from occupational exposure. This study assessed the serological and urinary levels of AFs in workers exposed to potentially contaminated dusts in two mills.

[Exposure to Saccharopolyspora rectivirgula among cattle breeders in the province of Reggio Emilia and the risk of extrinsic allergic alveolitis (farmer's lung)].

Introduction: Nearly 2.350 dairy farms (and 137.000 milk cows) are located in the province of Reggio Emilia, Italy, to produce the famous Parmigiano-Reggiano" cheese.

Exposure to cobalt in the welding process with stellite.

In some small factories producing moulds for ceramic tiles using a cobalt alloy (stellite), environmental and biological (CoU) monitoring was conducted for eight workers employed in gas-shielded arc (MAG) and oxy-acetylene welding processes. During oxy-acetylene braze-welding, the exposure to cobalt is very low as are urinary cobalt concentrations. On the other hand, during the MAG welding process, the exposure levels can exceed the TLV-TWA levels and correlated well with CoU at the end of a working shift.

[The cases of accident in the ceramic tile industry in relation to the age and job seniority of the workers].

A study was made of 3,368 workers in 36 ceramic plants in the Scandiano area (Reggio Emilia, Italy) during the year 1990; 403 had an accident during the observation period. The incidence and severity of the accident were correlated to age, job (low, intermediate, high accident risk), duration of employment as at 1.1.

[Esophageal atresia, today].

In recent years there have been remarkable improvements in the treatment of babies with congenital esophageal atresia. This improvement in survival and in preservation of esophagus is due: to progress in neonatal anesthesia and in preoperative and postoperative intensive care; to progress in surgical management of associated anomalies (mainly congenital malformations of the heart); to progress in surgical management of the malformation. Esophageal anastomosis may be performed in the majority of babies with "long gap" esophageal atresia by operative techniques for lengthening of the upper esophageal segment or by elongation of the upper and lower pouches by means of bougienage or mercury-filled bag.

[Surgery of malformations of extrahepatic bile ducts in childhood].

The actual hypothesis on the etiology and pathogenesis of neonatal hepatitis, intrahepatic and extrahepatic biliary atresia and choledocal cyst is that these disorders can be different results or permissible outcomes of a single basic process: infantile obstructive cholangiopathy. This hypothesis can explain the failure of many infants with operable extrahepatic biliary atresia to do well following surgically successful anastomosis. Very possibly no surgical mode of therapy will cure a significant fraction of infants with biliary atresia (correctable and non-correctable types) because the basic disease process actually produces portal fibrosis and destroys intrahepatic bile ducts as well.

[Urinary incontinence in the neuropathic bladder in children. Treatment using an artificial urinary sphincter].

The neurogenic urinary incontinence can be successfully managed by implantation of an artificial urinary sphincter. The most important requirement for implantation is the recognition that the patient has failed to respond to well-accepted conservative measures or is an unsuitable candidate for such conservative measures. It is necessary to rule out the presence of detrusor hyperreflexia or to show that, if it exists, hyperreflexia can be easily pharmacologically controlled.

[Long=term evaluation of renal damage in primary vesico-renal reflux after corrective surgery].

Traditionally 3 mechanisms are responsible for the development of renal damage when primary vesico-renal reflux is present: reflux is a manifestation of abnormal embryological development of the ureteral bud, with subsequent dysplasia; sterile reflux damages the kidney, perhaps trough a mechanical or/and an immunological mechanism; renal damage occurs as a result of the reflux of infected urine into susceptible renal papilla (intrarenal reflux). Whatever the mechanism, it is apparent that reflux and renal damage are intimately related. It does appear that for the most part damage is done at an early age.

[Trans-atrial correction of ventricular septal defects in infancy and childhood (author's transl)].

The Authors reviewed their surgical experience in correction of ventricular septal defects through tricuspid valve. 57 patients out of 59 operated for surgical closure of V.S.

[Myocardial protection during repair of congenital heart disease in infants (author's transl)].

The authors use the Bretschneider's cardioplegic solution at 4 degrees C as myocardial preservation in 45 open-heart cases in infants. Using moderate hypothermia at 28 degrees C, the mean myocardial temperature is 17.2 degrees C, using profound hypothermia at 18 degrees C, the mean myocardial temperature is 11.
