We examined how traditional farmers preserve the genetic diversity of a local common carp (Cyprinus carpio), which is locally referred to as "paddy field carp" (PF-carp), in a "globally important agricultural heritage system" (GIAHS), i.e., the 1,200-y-old rice-fish coculture system in Zhejiang Province, China. Our molecular and morphological analysis showed that the PF-carp has changed into a ...

Eugene Massachusetts Ins Cambridge, SUMMARY A program was written to solve calculus word problems. The program, CARPS (CAlculus Rate Problem Solver), is restricted to rate problems. The overall plan of the program is similar to Bobrow's STUDENT, the primary difference being the introduction of "structures" as the internal model in CARPS. Structures are stored internally as trees, each structure...

metals bioaccumulation in five organs of cirrhinus  mrigala , labeo  rohita and catla catla captured from three industrial and sewage polluted downstream sites (shahdera = b, sunder = c and balloki = d) were compared with a non-industrial upstream site (siphon = a) during high (post monsoon) and low (winter) flow seasons of river ravi. mean concentrations of metals were significantly higher in ...

This experiment was conducted for 150 days in 15 earthen ponds, 100 m2 in surface area and 1.2 m in depth, at the Institute of Agriculture and Animal science (IAAS), Rampur, Chitwan, Nepal. One cage (1.5 x 1.5 x 1 m and water volume of 2-m3) covered with 1-cm mesh net was suspended in each of the treatment ponds. There were one control and four treatments with three replicates each: carps at 1 ...

The capacity of organisms to rapidly evolve in response to environmental changes is a key feature of evolution, and studying mutation compensation is a way to evaluate whether alternative routes of evolution are possible or not. Common carps (Cyprinus carpio) carrying a homozygous loss-of-function mutation for the scale cover gene fgfr1a1, causing the 'mirror' reduced scale cover, were introduc...

Graphene-based materials with a three-dimensional (3D) framework have been investigated for a variety of biomedical applications because of their 3D morphology, excellent physiochemical properties, volume stability, and their controllable degradation rate. Current knowledge on the toxicological implications and bioavailability of graphene foam (GF) has major uncertainties surrounding the fate a...
