Cables and wires, which are essential parts of equipment for the transmission of both information and electricity, contain valuable materials including copper (Cu) and aluminum (Al). This experimental work evaluates the use of mechanical processing (grinding and sieving), followed by spouted bed elutriation, for separation of the valuable materials (steel-coated copper, copper, and aluminum) present in waste coaxial and internet cables. A recovery efficiency of approximately 90% was achieved for the steel-coated copper in coaxial cables. For in ternet cables, the copper recovery efficiency was approximately 87%. These findings dem on strate that it is possible to separate, recover, and recycle the valuable materials (metals) present in waste cables using simple, low-cost, and efficient mechanical processing followed by spouted bed elutriation.

The preference-performance relationship in plant-insect interactions is a cen- tral theme in evolutionary ecology. Among many insects, eggs are vulnerable and larvae have limited mobility, making the choice of an appropriate oviposition site one of the most important decisions for a female. We investigated the evolution of oviposition preferences in Drosophila melanogaster Meigen and Drosophila simulans Sturtevant by artificially selecting for the preference for 2 natural resources, grape and quince. The main finding of our study is the differential responses of D. melanogaster and D. simulans. Although preferences evolved in the experimental populations of D. melanogaster, responses were not consistent with the selection regimes applied. In contrast, responses in D. simulans were consistent with expectations, demonstrating that this species has selectable genetic variation for the trait. Furthermore, crosses between D. simulans divergent lines showed that the genetic factors involved in grape preference appear to be largely recessive. In summary, our artificial selection study suggests that D. melanogaster and D. simulans possess different genetic architectures for this trait.

BACKGROUND:Obstructive jaundice is a common condition in advanced digestive *** procedures can improve quality of life and allow patients to attempt a systemic *** anastomosis is still the procedure of choice for patients in many *** a surgical bypass is not possible,biliary drainage can be done by placing endoscopic or transparietal stents,which are less durable methods even when an expandable stent is employed. METHODS:A 47-year-old male with an excellent clinical status and a previous cholecystectomy and an exploratory laparotomy for advanced gastric cancer was referred with obstructive jaundice.A preoperative CT scan showed a dilated bile duct and a small mass at the distal hepatic *** other signs of metastasis were found.A surgical bilioenteric anastomosis was *** surgery,a distal choledochal obstruction and a mesenteric retraction by a lymph node mass prevented the jejunum to ascend for a bilioenteric anastomosis. Surgically,an alternative bilioenteric bypass was performed by means of an ileal loop interposition between the bile duct and the jejunum. RESUlT:The recovery of the patient was uneventful and his bilirubin levels normalized after one *** patient was then referred for systemic chemotherapy. CONClUSIONS:This alternative biliary bypass can be safely and easily performed,and may be a good alternative for patients already referred for surgery because of a better life expectancy and when the jejunum is not an alternative.
