USING ROTATING SPRINKLER GUNS IN CENTRE‐PIVOT IRRIGATION SYSTEMS †
2019
The use of centre-pivot irrigation systems has significantly increased in the last few decades, since they are easier and less time-consuming to manage compared to other irrigation systems. Standard high-pressure impact sprinklers, low-pressure spray sprinklers or LEPA (Low Energy Precision Application) systems are usually combined with a centre-pivot irrigation system (CP-SYS). However, when applying waste water or with reclaimed effluents that are extremely dirty, small nozzle sizes that require CP-SYS could get plugged. As an alternative to common centre-pivot irrigation systems, this paper analyses the ‘geometry’ of areas irrigated by rotating sprinkler guns in a centre-pivot irrigation…
Extensive molecular analysis of patients bearing CFTR-related disorders.
2012
Cystic fibrosis transmembrane conductance regulator (CFTR)–related disorders (CFTR-RDs) may present with pancreatic sufficiency, normal sweat test results, and better outcome. The detection rate of mutations is lower in CFTR-RD than in classic CF: mutations may be located in genes encoding proteins that interact with CFTR or support channel activity. We tested the whole CFTR coding regions in 99 CFTR-RD patients, looking for gene mutations in solute carrier (SLC) 26A and in epithelial Na channel (ENaC) in 33 patients who had unidentified mutations. CFTR analysis revealed 28 mutations, some of which are rare. Of these mutations, RT-PCR demonstrated that the novel 1525-1delG impairs exon 10 s…
Laparoscopic surgery of deferential reflux in pediatric and adolescent varicocele
2009
BACKGROUND: This study aimed to assess whether deferential reflux in pediatric and adolescent varicocele can be successfully treated laparoscopically. MATERIALS AND METHODS: Since 2001 at our institution, 148 boys were evaluated for a left varicocele. Preoperatively,all the patients underwent ultrasound scan assessment of testicular volume and color-Doppler US (CDUS)to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. Boys with ISV reflux were treated by laparoscopic transperitoneal Palomo; boys with isolated deferential reflux or associated to ISV reflux were laparoscopically managed adding to the former procedure, coagulation or clipping of ref…
The role of Doppler ultrasonography in determining the proper surgical approach to the management of varicocele in children and adolescents
2006
In a study from Italy, colour-Doppler ultrasonography was a reliable diagnostic tool in the preoperative assessment of patients with varicocele. The authors also found that it helped to distinguish those who could be treated laparoscopically from those who should be treated by microsurgical subinguinal ligature. OBJECTIVE To investigate whether colour Doppler ultrasonography (CDUS) is a reliable diagnostic tool for selecting patients with varicocele to undergo either laparoscopy or open microsurgical subinguinal ligation. PATIENTS AND METHODS In a 3-year period, 42 boys affected by left varicocele were evaluated before surgery by inguinal and scrotal CDUS. Using this method it was possible …
