Genetic properties of markers may discriminate between deletions and point mutations. We have designed a physical method for a direct characterization of deletions which also gives an estimate of their size....

With the increasing use of the rocks as dimension stones, the necessity of an adequate technological characterization of these materials becomes necessary. This work presents the results of a technological characterization of eighteen Brazilian rock types commonly used as dimensi...

We present a genetic and physical characterization of the IncM plasmid pBWH1. A physical map was constructed for the enzymes EcoRI, BamHI, SalI, BglII, HindIII, MstII, and XhoI. A series of deletions and a series of subclones of pBWH1 were constructed and used to determine the lo...

Electron microscopic heteroduplex analysis and comparative restriction digests have been used to characterize lambda p123(209), the complementary pair of phages used in the Casadaban technique of gene fusion. Derivatives of lambda 1(209) constructed to carry fusions of the lac ge...

The drying of seeds of the pioneer species Cecropia glaziovii Snethlage is motivated due to its restoration characteristics of heterogeneous degraded forests. In this work the main goal is the physical and drying characterization of Cecropia glaziovii seeds in batch fluidized bed...

The synthesis of N4-methyl-2'-deoxycytidine and its fully protected mononucleotide, suitable for the oligonucleotide synthesis by phosphotriester method is described. A set of octanucleotides - d(CGCGCGCG), d(CG5mCGCGCG), d(CG4mCGCGCG) and dodecanucleotides - d(GGACCCGGGTCC), d(G...

ABSTRACT: Wood is a material that for years has been used by man for a variety of purposes, particularly in rural and civil constructions and furniture industry. The possibility of shortages of some wood species, the characterization of other unfamiliar species is an alternative ...

ABSTRACT The search for new pharmaceutical dosage forms and different drug delivery systems already used in therapeutics is a global trend, serving as an opportunity to expand the portfolio for the pharmaceutical industry. In this context, multiparticulate systems, such as pellet...

The study of the hydro-physical behavior in soils using toposequences is of great importance for better understanding the soil, water and vegetation relationships. This study aims to assess the hydro-physical and morphological characterization of soil from a toposequence in Galia...

The growing popularity of wooden panels renders this market segment increasingly competitive. MDF (Medium Density Fiberboard), in particular, is widely employed for a variety of applications, including civil construction, furniture, and packaging. This paper discusses a study of ...

A technique for digital characterization and comparison of DNA fragments, using restriction enzymes, is described. The technique is being applied to fragments from the nematode Caenorhabditis elegans (i) to facilitate cross-indexing of clones emanating from different laboratories...

Mycoplasmavirus MVL2 is a nonlytic enveloped virion containing DNA. This DNA has been shown to be a double-stranded circular superhelical molecule of 11.8 kilobase pairs (7.8 X 10(6) daltons). The superhelix density is greater than that of phi X174 RFI but less than that of PM2 p...
