the world wide web becomes very popular recently and plays an influential role in english learning. by burgeoning role of source-based writing as partial fulfillment of tefl courses and vast use of the internet, lack of empirical studies to explore these areas is obvious. this study aimed to explore the effect of the amount of familiarity with the web (internet literacy) on junior english stude...
The entomogenous nematode Steinernema feltiae was encapsulated in an alginate matrix containing a tomato seed. When these capsules were placed on 0.8% agar for 7 days, the seed germinated and ca. 20% of the nematodes escaped from the capsules, whereas only 0.1% escaped from capsules without seeds. When capsules containing nematodes and a seed were planted into sterilized or nonsterilized soil, ...
ambulatory blood pressure (BP) as well as on the magnitude of leg edema of treatments using LER, amlodipine (AML), or hydrochlorothiazide (HCT) in patients with confirmed ambulatory hypertension (daytime systolic BP 135mmHg). A total of 121 eligible patients (66M/55F, mean age of 62.7 7.1 yrs) were randomized to either LER 10 mg (n 39), AML 5 mg (n 39) or HCT 12.5 mg (n 43) for 4 weeks. They we...

We prove that both minimum and maximum traveling salesman problems on complete graphs with edge-distances 1 and 2 (denoted by min TSP12 and max TSP12, respectively) are approximable within 3/4. Based upon this result, we improve the standard approximation ratio known for maximum traveling salesman with distances 1 and 2 from 3/4 to 7/8. Finally, we prove that, for any 2 > 0, it is NP-hard to ap...
