High input costs combined with multiple management and material inputs have threatened cotton productivity. We hypothesize that this problem can be addressed by a single fertilization at flowering with late sowing in a moderately populated plant stand. Field experiments were conducted to evaluate the cotton biomass accumulation, phosphorus dynamics, and fiber quality under three planting densities (low, 3 × 104; moderate, 6 × 104; and dense, 9 × 104 ha−1) and two cultivars (Zhongmian-16 and J-4B). High planting density had 6.2 and 12.6% larger stems and fruiting nodes m−2, while low density produced a 37.5 and 59.4% maximum height node ratio. Moderate density produced 26.4–15.5%, 24.7–12.6%, and 10.5–13.6% higher biomass accumulation rate at the peak bloom, boll set, and plant removal stages over low and high density in both years, respectively. J-4B produced a higher reproductive organs biomass yield when compared with Zhongmian-16 in both years. This higher biomass formation was due to both the higher average (0.8 VT kg·ha−1·d−1) and maximum (1.0 VM kg·ha−1·d−1) reproductive organ phosphorus uptake, respectively. Plants with low density had 5.3–18.5%, 9.5–15%, and 7.8–12.8% greater length, strength, and micronaire values over moderate and dense plants, respectively. Conclusively, moderate density with J-4B is a promising option for improved biomass, phosphorus acquisition, and fiber quality under a short season.

Gravelly Soils

Many gravelly soils liquefied cases history especially in the 2008 Wenchuan earthquake warn that loose to moderate density of gravels have much potential to liquefy under a given earthquake shaking. The large diameter triaxial apparatus is a relative feasible means to explore the liquefaction mechanism of gravelly soils to some extent. Becker penetration test (BPT) could be droved hrough gravelly soils layer, but BPT was not directly correlated with field behavior. Because of a wider range of grain sizes than those reported from previous earthquakes, gravels characteristics liquefied in the Wenchuan earthquake are representative and universal. The gravels liquefaction evaluation method developed from the Wenchuan earthquake should be feasible for worldwide use. The recent and ongoing developments in gravels liquefaction was highlighted

As in furniture and product design, the handling of features such as junctions of street facades is a matter worthy of consideration. The article considers the role of the corner and corner buildings in the architectural relations of the street. It examines the role of corners in the urban structure and the reasons why they are no longer much used. A typology of corner building arrangements is proposed. Referring to affordance, legibility and Weber᾽s (1995) psychological approach to perceived architectural space, the paper discusses the value of clearly articulated corner constructions using selected examples. The dominant modes of building in the post-WWII period tend towards two extremes: high rise/high density and low rise/low density, both often characterised by disconnected building masses. Both modes reject the well-developed formats generally used up to the 1920s. These relied on moderate density, moderate height and conjoined buildings to create clearly defined, legible streets characteristic of an integrated urban fabric. This paper argues that certain morphologies make for better corner designs leading to more understandable street layouts. It also argues that quantitative recommendations in planning guidance are insufficient to ensure desirable outcomes in street design.

Method Of Assessment

An experiment is described in which G. tachinoides in an isolated secondary focus was marked with distinct colours during thirteen successive weeks and the fate of the groups studied by recaptures. The population was known to be declining from moderate density to great scarcity through the dry season and the wastage in the colour groups on the average proved to be 11½ per cent, per diem, rather more, probably, than the wastage in unmarked flies. Following Jackson's method of assessment the population is shown to fall from 6,000 at the end of October to 400 by mid-January. The ratio of the boy-hour rate to these numbers is worked out for each collection and it is found that when the boy-hour rate is above 50 it is not relative to population, but below 50 the rate falls as the population, allowing for the influence of weather on rate of catching.It is shown that under the conditions of the experiment there is an almost complete change of fly population each 5 or 6 weeks, though an occasional fly may survive 11 weeks. The proportion of male flies in the catches fell with increasing age from an initial 57 per cent, to 23 per cent, in the 6th week and no male fly surviving this period was caught.
