Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat ...

Densification in highly porous, isothermal firn occurs primarily by Newtonian sliding on grain boundaries, but the coordination number increases with density and restricts further sliding. At a relative density of about 0.6 the coordination number approaches 6 and sliding ceases to be a primary mechanism of densification; the resulting decrease in densification rate causes the critical point in...

The purpose of this study was to determine whether high-school football players showed risks of fluid deficits during two-a-day training (Part 1), and whether implementing a drinking strategy could acutely improve the markers of hydration (Part 2). In Part 1, pre-training urine specific gravity (USG) and pre- and post-training body weight were measured at the morning session for 5 consecutive d...

This study explores the extent to which richer central cities are associated with slower suburban sprawl. The authors use a unique approach to categorizing municipalities in urbanized areas based on their relative densities. Richness is measured in terms of the central city’s relative share of high-income households. The central finding (both for the decade from 1990 to 2000 and for 2000 to 200...

this experiment was conducted to evaluate the effects of different levels of crude protein and probiotic in diets on performance, egg quality  and blood biochemical and immunity parameters of laying hens. a completely randomized design with factorial method (2×4) was conducted in which two levels of crude protein (nrc and 10% lower than nrc recommendation) and 4 levels of probiotic (0, .025%, 0...

in this experiment, a total of 128 hy-line w36 hens at 63 weeks of age were used. the hens were put at random into 4 treatment groups (4 replicates and 32 hens per treatment) and were fed four different diets: three diets with different levels of spirulina (1.5, 2.0 and 2.5%) and one control group based on wheat and soybean meal. all birds were housed in commercial cages, had ad libitum access ...

One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...

________________________________________________________________________________ Abstract This study was performed to investigate the effects of different oils in the diets of laying quail on their performance, egg quality, serum lipids and fatty acid composition of egg yolk. One hundred and ninety two 12-wk old Japanese quail were allocated to eight groups with two replicates containing 12 qua...

OBJECTIVE The aim of the study was to evaluate genetic correlations between the behavioural profile and performance in laying hens as an indirect answer to the question whether the observed behavioural responses are associated with increased levels of stress in these birds. METHODS The assessment of birds' temperament was carried out using the novel objects test. The behavioural test was cond...

Abstract This study aims to assess the transportability of food waste disposer particles within a sewer system. A series laboratory studies has examined physical characteristics solid derived from domestic disposers. Particle size distributions and maximum settling velocity were measured for 18 common types, stored in publicly accessible database. are shown fit well with 2-parameter Gamma distr...
