The aim of this work is to establish a term structure of interest rates for corporate bonds in the Brazilian market, using the Nelson-Siegel model (1987). The yield curves were divided by the type of index and the rating level. It was possible to measure ... see more

Aim of study: To estimate the heritability and genetic correlations for lactation curve traits in buffaloes.Area of study: The buffalo cows were raised on properties located in the states of São Paulo, Ceará and Rio Grande do Norte, Brazil.Material and me... see more

Soil erosion in highly gullied regions of Kashmir valley is a serious global issue due to its impacts on economic productivity and environmental consequences such as land disintegration and one of the most affected areas is Lolab which is flood-prone and ... see more

Rice tillering is a crucial stage for yield formation. Deep understanding of the relationship between tillering dynamics and yield formation in a particular agrosystem is crucial to boost rice productivity. Research on rice tillering is mainly focused on ... see more

This paper attempts to provide an economic interpretation of the factors thatdrive the movements of interest rates of bonds of different maturities in acontinuous-time no-arbitrage term structure model for Chile. The dynamics ofyields in the model are exp... see more

This paper estimates the term structure of natural interest rates for Brazil, a generalization of the concept of natural rate of interest for the yield curve. First, the Diebold-Li (2006) model is estimated with real yields. The latent factors of this mod... see more

Poultry manure, cow dung and swine manure were digested in cube-shaped anaerobic digesters of equal volume but different surface areas (SAs) (5.38, 10.0 and 11.6 dm2) in a two-factor experiment. The digesters were agitated once a day during the experiment... see more

A pilot study was conducted in order to assess the effect of a.m./p.m. milkings on the shape of the lactation curve during a normal lactation. Data from a.m. and p.m. milkings from 86 Romanian Spotted cows were used. Cows calved during January, February a... see more

The aim of the paper was to study the evolution of the chemical composition and somatic cell count during lactation in Romanian Black and White cows and effect of calving season on the shape of the lactation curve. Lactations form 125 multiparous cows wer... see more
