Homestake, Gallex and GNO data reveal variability of the solar neutrino flux. Kamiokande records for 1996-2001 oscillations at 9.43 12.6 yr$^{-1}$, well within a range (6-16 yr$^{-1}$) that, according to helioseismology, may be related internal rotation. A nuclear-decay experiment Brookhaven National Laboratory (for 1982-86) reveals strong 11.2 13.2 yr$^{-1}$. Similar are found in measurements ...
certain potato cultivars such as native potato species (nps) from the andes are known to have resistances to different pests and diseases. some accessions are also interesting from a nutritional and culinary perspective. a collection of 35 nps and 11 old spanish accessions were analysed for streptomyces scabies, rhizoctonia solani and globodera rostochiensis, as well as dry matter, reducing sug...
variability of tidal volume and respiratory rate in normally breathing man has long been demonstrated [1]. however because of lack of knowledge and technology primary ventilators could only deliver a fixed tidal volume in a fixed rate the so called volume controlled ventilation (vcv). vcv was volume preset time triggered and cycled and there was no synchronization with patient’s breaths. at tha...
In order to investigate the genetic diversity of morphological traits in 121 genotypes of lima, red and pinto beans, and to study the relation between characters, and to get better understanding of factors affecting the interaction between characters by multivariate analysis, an experiment was conducted in 1997 as a simple lattice design at the Research Station of Agricultural College, Isfahan ...
abstract climate variability empowers critical consequences on sustainability of soil and water resources. in this paper the trend of annual and seasonal time scale of temperature (minimum, maximum, average), relative humidity (minimum, maximum, average), precipitation, wind speed, extreme events, cloudiness, reference evapotranspiration employing mann-kendall and least square errors were studi...
selection of genotypes based on high value of heritability and forecasted genetic conditions would be an effective method for improvement of wheat cultivars. the present investigation was carried out to estimate the genetic variability of agro-physiological characters using biometrical genetic techniques in 20 bread wheat genotypes under irrigated condition. for this purpose an experiment was c...
in this study, long-term trends and abrupt changes of hydro-climatic variables was investigated in the observed period 1971-2000 for aidoghmoush basin using mann-kendall nonparametric test and cumulative curve of climatic variables-runoff, respectively. results show decrease trends for rainfall and runoff and increase trend for temperature by the mann-kendall test with a confidence level of 99%...
