Solving Maximum Clique Problem for Protein Structure Similarity [PDF]

open access: yes, 2009
A basic assumption of molecular biology is that proteins sharing close three-dimensional (3D) structures are likely to share a common function and in most cases derive from a same ancestor.

Dietary Energy Level Promotes Rumen Microbial Protein Synthesis by Improving the Energy Productivity of the Ruminal Microbiome

open access: yesFrontiers in Microbiology, 2019
Improving the yield of rumen microbial protein (MCP) has significant importance in the promotion of animal performance and the reduction of protein feed waste.

Addendum to "Coulomb Interaction Does Not Spread Instantaneously" [PDF]

open access: yesHadronic J. 24 (2001) 253, 2001
We describe the results of experimental research by configurations changed with respect to the original experimental configuration [1]. In this way it is demonstrated that the basic part of the signal registered is due to the Coulomb electric field and does not originate from the transversal electromagnetic wave.

Comparative genomics of rumen methanogens : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biochemistry at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
Methane (CH4) emissions from agriculture represent around 9% of global anthropogenic greenhouse gas emissions. The single largest source of this CH4 is animal enteric fermentation, predominantly from ruminant livestock, where it is produced mainly in ...

Long-Term Encapsulated Nitrate Supplementation Modulates Rumen Microbial Diversity and Rumen Fermentation to Reduce Methane Emission in Grazing Steers

open access: yesFrontiers in Microbiology, 2019
This study investigated the long-term effects (13 months) of encapsulated nitrate supplementation (ENS) on enteric methane emissions, rumen fermentation parameters, ruminal bacteria, and diversity of archaea in grazing beef cattle.

Lagrangian Approaches for a class of Matching Problems in Computational Biology [PDF]

open access: yesarXiv, 2006
This paper presents efficient algorithms for solving the problem of aligning a protein structure template to a query amino-acid sequence, known as protein threading problem. We consider the problem as a special case of graph matching problem. We give formal graph and integer programming models of the problem.

Studies on the growth, viability, and lipids of Streptococcus bovis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science [PDF]

open access: yes, 1966
In their comprehensive review of rumen metabolism, Annison and Lewis (1959) emphasised the symbiotic relationship between the metabolic activities of the mixed population of anaerobic bacteria and ciliated protozoa, and the digestion of fodder consumed ...

Permanent Rumen Cannula

open access: yesJournal of Dairy Science, 1969
Abstract A permanent rumen cannula for use in fistulated cattle is described. The cannula is constructed of acrylic resin and consists of the main stem, inner and outer rings, cap, and a polyurethane collar or cushion of a pliable nature. The main stem is threaded to accommodate a screw cap and to permit adjustment of the outer ring according to the ...

CSA: Comprehensive comparison of pairwise protein structure alignments [PDF]

open access: yesN° RR-7874 (2012), 2012
CSA is a web server for the comprehensive comparison of pairwise protein structure alignments. Its exact alignment engine computes either optimal, top-scoring alignments or heuristic alignments with quality guarantee for the inter-residue distance based scorings of contact map overlap, PAUL, DALI and MATRAS.
