Wind speed and optical stratifi cation porosity (OSP) were measured at various heights inside a coastal protective forest thinned to different stem densities to assess whether any characteristics of the wind profi le in the coastal protective forest could be predicted from OSP. OSP was defi ned as vertical distribution of the proportion of sky hemisphere not obscured by tree elements inside a f...

The aim of this study was to estimate amount of inbreeding coefficient in Shal sheep and its impact on growth performance. Pedigree information and body weight at different ages (birth weight, 3 month weight, 6 month weight, 9 month weight and 12 month weight) were used from 6692 lambs from 90 rams and 1007 ewes. Data were collected on Ghazvin sheep breeding station during 1997-2013. Estimation...

We use factor augmented vector autoregressive models with time-varying coeffi cients to construct a financial conditions index. The time-variation in the parameters allows for the weights attached to each financial variable in the index to evolve over time. Furthermore, we develop methods for dynamic model averaging or selection which allow the financial variables entering into the FCI to chang...

In this study the symbiotic interactive effect of different Bradyrhizobium japonicum strains with six soybean cultivars were evaluated under fi eld conditions. The rhizobial strains ASR011, USDA123 and CB1809 respectively showed hostcultivar specifi city with JS335, Lee and Bragg. B. japonicum ASR011 recorded the highest nodulation and nitrogenase activity with all the studied cultivars. Genera...

We proposed a blind watermarking technique to embed the watermark in JPEG compressed domain. Low frequency DCT coeffi cients are extracted to form an M-dimensional vector. Watermarking is achieved by modifying this vector in order to point to the centroid of a particular cell. This cell is determined according to the extract ed vector, private keys and the watermark. A dual-key system is used t...

Using the short-term multi-sector econometric model, this paper discusses in detail the multiplier effect of public investment in Japan. After examining its fundamental characteristics, the differ ence in government investment multiplier by the pattern of investment distribution among indus tries and the factors causing such a difference are analyzed. According to the simulation results, the mu...

PELIKÁN PETR, MARKOVÁ JANA. 2016. The use of Regression Triplet in Hydraulic Modelling on the Example of Determination of Overfall Coeffi cient. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(2): 497–502. The paper is focused on a hydraulic problem of water overfall on hydrotechnic structures, especially outlets and spillways of water reservoirs. The main parameter o...

Working papers of the Federal Reserve Bank of Cleveland are preliminary materials circulated to stimulate discussion and critical comment on research in progress. They may not have been subject to the formal editorial review accorded offi cial Federal Reserve Bank of Cleveland publications. The views stated herein are those of the authors and are not necessarily those of the Federal Reserve Ban...

The recent outbreak of Ebola in West Africa will leave a legacy signifi cantly deeper than the morbidity and mortality caused directly by the disease. Ebola deaths have been disproportionately concentrated among health personnel. By May, 2015, 0·02% of Guinea’s population had died due to Ebola, compared with 1·45% of the country’s doctors, nurses, and midwives. In Liberia and Sierra Leone, the ...

The Neutral Theory of Evolution (NTE) proposes mutation and random genetic drift as the most important evolutionary factors. The most conspicuous feature of evolution is the genomic stability during paleontological eras and lack of variation among taxa; 98% or more of nucleotide sites are monomorphic within a species. NTE explains this homology by random fi xation of neutral bases and negative ...
