It is therefore essential to anneal the as-cast alloys in vacuum at a high temperature for a long time (approximately 1,323 K, 30 days) to gain the desired 1 13 phase.
Streak-seeding is an effective method for producing single crystals, however, crystals suitable for X-ray analysis are obtained only when the crystallization droplets are allowed to equilibrate for a relatively long time (approximately three weeks) before seeding.
In this study, five construction methods with different details are tested to analyze the effect of long-time (approximately 6 hours) onsite welding on the high-strength concrete for the joint between gusset plates and the embedded plate in a high-rise building.
The brown mesite had high Ne (200,000 350,000) for a long time until approximately 30 kya, when it faced a drastic decline to 23,000.
Its long generation time, approximately eight years to sexual maturity, also poses an obstacle to tree improvement through traditional breeding techniques.
While we were able to infer the presence of additive genetic variance for morphometric traits from two generations of pond data, more stringent analyses including F2 and F3 are planned although data are not yet available due to the relatively long generation time (approximately 2.5 years).
This cohort was followed for a long time, with regular (approximately biweekly) reporting of daily symptoms, and ambient co-pollutants were measured and accounted for in analyses.
In this trial all the horses had a significant reduction in vitamin E levels for a relatively long period of time (approximately 3+ years).
To achieve the first phase of the reaction requires quite long incubation times (approximately 8 h), thus screening using raw wheat straw (that is, In-WS) provides a means to find variants that display improved initial catalytic rates, which can result either from the improvement of intrinsic catalytic properties of the xylanase, or from an increase in enzyme production.
Especially, for very long time durations, e.g. "approximately between 4 to 8 weeks" the extreme values should be appropriate.
However, the dot blotting procedure is laboratory-dependent and time-consuming which needs long result turn-around time (approximately 6 h) [20,21].
