The various embodiments herein provide a method for derivation and long term establishment of ground state pluripotent embryonic stem cells. Further the embodiments herein provides a method to inhibit the ERK and TGF β signalling pathways for long term maintenance of the embryonic stem cells. The R2i mouse embryonic stem (ES) cells are derived from 3.5 day blastocysts. The mouse ES cells are cultured in media containing R2i and 2i inhibitors of ERK and TGF β pathways. The ES cells are subjected to in vitro and in vivo differentiation. The ES cells are subjected to RT-PCR and qRT-PCR, flow cytometry and karyotyping. The result reveals that the R2i maintains the ground state of ES cells and self renewal. Also R2i increases embryonic cleavage and clonal propagation of ES. Further R2i asserts genomic integrity and pluripotency of ES.

A portable cofferdam and method for use in stabilizing the subsurface of box culvert structures. The portable cofferdam is inserted inside the tubular section of large box culverts, which are often used as road crossings over streams, creeks and small rivers. The portable cofferdam is designed as a chamber having an open top end and open bottom end with a floor seal to engage against the box culvert floor. Once inside the culvert, the chamber floor seal is compressed against the culvert floor by means of an expansion device which extends against the culvert ceiling. Once a proper seal is created against the culvert floor, the chamber is dewatered. With the culvert floor exposed, a hole can be drilled through the culvert floor bottom and grout or other hard curing material is pumped into the subsurface void for stabilization of the box culvert structure.

A selection system free of antibiotic resistance genes, which is based on the use of an araD gene as a selection marker carried on a vector which is inserted in a bacterial strain deficient of the araD gene. The araD gene from E. coli encodes the L-ribulose-5-phosphate-4-epimerase. A method of selecting the cells transformed with a plasmid, which contains the araD gene. The non-antibiotic selection marker makes the system suitable for producing therapeutics. The araD gene is not essential for growth of the host but manipulation of it affects the growth under certain selective conditions. Deletion of araD leads to accumulation of substance which is toxic to the host but not to humans. The araD gene is relatively small and therefore a small plasmid may be constructed, which requires less energy for replication, and leads to increased growth rate and yield.
