abstract environmental pollution has made urban citizens to focus on landscapes. in this respect lown is very important plant. from the other hand water resources in many arid and semi-arid region is saline. for this purpose a research was conducted to study the effect of sprinkling irrigation with saline water on growth parameters of three lown varieties. these varieties were poa partensis, fe...

The Lown grading system for ventricular arrhythmias has been used in observational and experimental studies of ischaemic heart disease. This grading system uses three levels of ventricular premature depolarisation frequency and four complex features to assign patients to one of seven grades. We tested several of the major assumptions of the Lown grading system in a group of 400 patients who had...

Generally, <30% of dairy cattle's nitrogen intake is retained in milk. Large amounts of nitrogen are excreted in manure, especially in urine, with damaging impacts on the environment. This study explores the effect of lowering dietary degradable nitrogen supplies--while maintaining metabolisable protein--on dairy cows' performance, nitrogen use efficiency and gas emissions (NH3, N2O, CH4) at ba...

Not long before the completion of first issue 2021 we received message that Bernard Lown had died. Of course, this is a shock and great loss, despite fact he almost reached ...

VAR analysis on a measure of bank lending standards collected by the Federal Reserve reveals that shocks to lending standards are significantly correlated with innovations in commercial loans at banks and in real output. Credit standards strongly dominate loan rates in explaining variation in business loans and output. Standards remain significant when we include various proxies for loan demand...

His bundle recordings were obtained in three patients with histories of recurrent supraventricular tachyeardias and electrocardiograms demonstrating a short P-R interval with a normal QRS (the Lown-Ganong-Levine syndrome). The His bundle electrograms obtained during sinus rhythm demonstrated a normal A-H (atrium-to-His bundle) time in one patient and a low normal A-H time in two patients. The H...
