Abstract

Ancient DNA (a-DNA) studies in past three decades has been uplifted from short stretch archaeological mtDNA retrieval to reconstruction of complete mitochondrial genome sequence using next generation sequencing. Study of a-DNA acts as validating tool to test the assumed hypothesis used in origin, evolution, diversification, distribution, domestication and extinction of species; although, scientific progression in the field is frequently hindered by erroneous reports due to contamination and other technical bottlenecks. With the advent of appropriate methodologies such as 3’-C3 spacer tagged oligonucleotide blocking, shotgun sequencing, amplicon sequencing Polymerase Chain Reaction, single primer extension methodology, development of broad spectrum ancient sequence primer, slippage proof amplification methods, use of multiplexing strategy in PCR (Polymerase Chain Reaction) amplification, etc. in a-DNA research try to minimize the difficulties associated with it. Present review highlighted the pitfalls as well as prospects of a-DNA study and tries to assess the significance and acceptability of a-DNA research for its future application in understanding of evolutionary biology.

Abstract

Palynological investigation has been undertaken with tile subsurface Cenozoic sediments of Ganga basin to establish biostraligraphy and environment of deposition. Samples from four bore holes viz. Puranpur, Matera, Gandak and Raxaul under study have yieldcd palynomorphs and other microfossils. Palynoassemblage recovered from the older Cenozoic sedimcnts of thc four bore holes has becn analyzed in this paper to ascertain the age and environment of deposition. Rich palynoasscmblage recovered i'rorn the Ganga basin sediments compare closely with the palynoassemblage recovered from Palcoccne-Eocene sediments of other Tertiary basins in India. Occurrence of triporate 'Normapolles' type pollen grains in the assemblage is additional significant record. The palynoassemblage suggests a predominantly tropical warm humid climate with coastal brackish water influence. In addition, reworked microfossils of early and late Paleozoic, Mesozoic ages have becn recovered in the lower Tertiary palynoassemblage.

Abstract

The fee structure of many self-financed colleges in India may be exorbitant to aspiring students coming from the financially weaker section. The problem is even more pertinent when staying cost gets added for outside Mumbai students. The paper aims to focus on the process of building a mechanism to bring technical education within reach of the financially needy students, who are admitted to K.J. Somaiya College of Engineering Mumbai (KJSCE). With an aim of raising funds to support such needy students, employees of KJSCE came together and extended a helping hand to establish an organization named as "PUSH" (People United for Students' Help). This paper describes the functioning of PUSH-KJSCE and its long-lasting impact on the lives of low-income students. PUSH-KJSCE, a management-inspired practice in KJSCE, ensured an economic support system as well as much-needed facilities to financially weaker students. As a result of this, it not only makes the students confident, but it also helps them to fulfil their dreams to become professionally qualified. The PUSH KJSCE is a success story of the best management practices which spread the rays of hope in the lives of young minds, such that they are no more hindered by financial obstacles and it also creates awareness in them to contribute and make this model sustainable.
