A Group of Red, Lyα Emitting, High Redshift Galaxies

We have discovered two new high redshift (z = 2.38) galaxies, near the previously known z = 2.38 galaxy 2139−4434 B1 (Francis et al. 1996). All three galaxies are strong Lyα emitters, and have much redder continuum colors (I − K ∼ 5) than other optically-selected high redshift galaxies. We hypothesize that these three galaxies are QSO IIs; radio-quiet counterparts of high redshift radio galaxie...

شناسایی بهترین ترکیب مالچی و زمان کاشت جهت انجام هیدرومالچینگ و تأثیر این خصوصیات بر برخی صفات کمی و کیفی چمن

Turfgrass is important in urban landscape and by considering that organic matter has a important roll in improving physical and chemical soil characteristics using an organic matter instead of manure and MSW seems necessary .in this research the possibility of using new method of culture such as hydromulching (i.e. mixing seed, organic matter, water, and fertilizer and then distributing it) spe...

Incorporation of Tritiated Cytidine into Ribonucleic Acid by Isolated Pea Nuclei

A new method for the isolation of the nuclei from plant tissue has been devised. This method consists in passing the plant tissue through a set of spring-loaded, counter-rotating rollers and collecting the liberated nuclei in sucrose solution containing calcium ions. A semi-automatic machine which couples the rollers with a special tissue chopping device has been constructed. It has been shown ...
