In this paper, we presented the datasets generated using Chose Game representation (CGR) and Choase Game Representation of Frequencies (FCGR) of bacterial and archaeal 16S rRNA sequences. The data in the form of graphical representations was yielded with the help of ENDMEMO tool. The computational representation of these data datasets is useful for studies and interpretation of microbial sequen...
We study the numerical solutions to semi-infinite-domain two-point boundary value problems and initial value problems. A smooth, strictly monotonic transformation is used to map the semiinfinite domain x ∈ 0,∞ onto a half-open interval t ∈ −1, 1 . The resulting finite-domain twopoint boundary value problem is transcribed to a system of algebraic equations using ChebyshevGauss CG collocation, wh...
Concerns about the genetic erosion of crop genetic resources (CGR) were first articulated by scientists in the mid-20th century and have since become an important part of national policies and international treaties. The C-8 (Plant Genetic Resources) section of the Crop Science Society of America (CSSA) was created in 1990 in response to these concerns. Over the last 50 yr, both ex situ and in ...
Genotype, environment and agronomic practices are key determinants of crop growth productivity which important to provide food, feed, raw materials income small holder farmers in Africa. The study was conducted at Crop museum, Sokoine University Agriculture, Morogoro, Tanzania investigate physiological response groundnut calcium phosphorus nutrition among three improved genotypes Mangaka (G1), ...
A field experiment was conducted during the winter (rabi) seasons of 2015–16 and 2016–17 at Punjab Agricultural University, Ludhiana, to study effect staggered sowing on growth indices, photosynthetic parameters productivity barley (Hordeum vulgare L.) in relation different cutting management. The laid out a split-plot design with 3 dates, viz. 15 October, 30 October November main plots 5 manag...
The sprinkler irrigation system is the most widely used for rubber in a nursery. However, method associated with high water loss during irrigation. In view of this, an experiment was conducted to assess effect different systems on growth dynamics, leaf ratio analyses, productivity, and use efficiency seedlings. treatments were systems; soil + overhead (CON), growing media (GM) drip (DRP), GM ca...
A coupled regional and local model is required when groundwater flow solute transport are to be simulated in areas of interest with a finer grid while aquifer boundary major stresses should retained coarser grid. The also maintain interactions between the systems. In Beijing Plain (China), assessment managed recharge (MAR), pollution caused by rivers, capture zone well fields, land subsidence a...
Coffee is one of the most socioeconomically important crops worldwide. Currently, environmental variations due to climate change are affecting coffee development and growth. Therefore, it evaluate areas that offer a different environment during seedling stage since fundamental for successful cultivation. Four municipalities located at altitudes in Department Nariño were selected: La Florida (18...
