to evaluate the effect of supplemental vitamin c (vc) levels on performance and immune response of broiler chicks, 300 day-old ross male broiler chicks were allocated to a completly randomized design of 5 treatments(500 and 1000 ppm in diet, 500 and 1000 ppm in drinking water and control). immunity was assessed as antibody production against infectious bronchitis virus (ibv) and newcastle disea...

A remarkable theorem by Clifton, Bub and Halvorson (2003) (CBH) characterizes quantum theory in terms of information–theoretic principles. According to Bub (2004, 2005) the philosophical significance of the theorem is that quantum theory should be regarded as a “principle” theory about (quantum) information rather than a “constructive” theory about the dynamics of quantum systems. Here we criti...

There are distinct differences between radiation characteristics of volcanic ash and meteorological clouds, conventional retrieval methods for cloud base height (CBH) the latter difficult to apply without substantial parameterisation model correction. Furthermore, existing CBH inversion have limitations, including involvement many empirical formulae a dependence on accuracy upstream products. A...

Mixed forests make up the majority of natural forests, and they are conducive to improving resilience resistance forest ecosystems. Moreover, it is in crown trees where effect inter- intra-specific interaction between them evident. However, our knowledge changes morphology caused by density, competition, mixture specific species still limited. Here, we provide insight on stand structural comple...

A neural network technique is used to quantify relationships involved in cloud–radiation feedbacks based on observations from the Surface Heat Budget of the Arctic (SHEBA) project. Sensitivities of longwave cloud forcing (CFL) to cloud parameters indicate that a bimodal distribution pattern dominates the histogram of each sensitivity. Although the mean states of the relationships agree well wit...
