this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...

in order to study the effect of chemical and biological fertilizers on silage corn under different plant densities, a split plot experiment was carried out in a randomized completely block design with three replicates in south western iran. the main plot included nitrogen fertilizer treatment at three levels (n1: with out chemical and organic fertilizers, n2: 75% chemical fertilizer + 100% orga...

As a teenager in a South Dakota hamlet (Pierpont, population 326 in the 1940 census) I had no idea that I would become a scientist. The only formal science course my tiny high school (40 students in four grades, taught by three teachers) offered was physics, taught by the sports coach (a history major) and featuring the ‘‘dissection’’ of a 1928 Overland (teacher: ‘‘I have been told that the mod...

  Background: Trait anger is associated with numerous physiological and psychological problems and is a social health problem. The current study aimed to evaluate the socio-demographic and nutritional determinants of trait anger in young males. Methods: In the current study, 150 young males aged between 14-44 years were randomly selected. General information was obtained and anthropometric ass...

The paper focuses on bio®lms subject to turbulent ̄ow and high liquid velocity (of the order of 1 m s) which can be found in heat exchangers, water distribution systems and in some wastewater reactors. An overall model describing bio®lm development is presented, which includes the effects of biomass detachment due to the hydrodynamic forces. A methodology for estimating substrate consumption fr...

COURSE DESCRIPTION: The course is designed for graduate students in biology wanting to aquire a more detailed working knowledge and appreciation of mammalian diversity in structure, function, ethology, and ecology. Knowledge and skills aquired in this course will be useful to field and laboratory studies in ecology, evolution, animal behavior, biogeography, wildlife management, and related disc...

The cost-effectiveness of sequencing pools of individuals (Pool-Seq) provides the basis for the popularity and wide-spread use of this method for many research questions, ranging from unravelling the genetic basis of complex traits to the clonal evolution of cancer cells. Because the accuracy of Pool-Seq could be affected by many potential sources of error, several studies determined, for examp...

UNLABELLED Many statistical problems in bioinformatics and genetics can be formulated as the testing of associations between a categorical variable and a continuous variable. A dynamic slicing method was proposed for non-parametric dependence testing, which has been demonstrated to have higher powers compared with traditional methods such as Kolmogorov-Smirnov test. We introduce an R package ds...

The emergence of eusociality ("true sociality") in several insect lineages represents one of the most successful evolutionary adaptations in the animal kingdom in terms of species richness and global biomass. In contrast to solitary insects, eusocial insects evolved a set of unique behavioral and physiological traits such as reproductive division of labor and cooperative brood care, which likel...
