Os coelhos têm capacidade de aproveitar parte das fibras devido ao processo fermentativo cecal e hábito da cecotrofia. Nesse sentido, uso de forrageiras conservadas como complemento alimentar é uma alternativa na criação visto que a ração comercial é o insumo mais oneroso na cunicultura. O objetivo deste trabalho foi avaliar o uso de silagem de girassol ou silagem de milho na alimentação de coelhos em crescimento sobre desempenho e viabilidade econômica da dieta.  Utilizou-se 15 animais de ambos os sexos, com 45 dias, distribuídos em 3 tratamentos e cinco repetições cada, durante 69 dias. Os tratamentos avaliados foram: dieta basal (DB), dieta basal e silagem de girassol (SG) e dieta basal e silagem de milho (SM). Animais alimentados com SM consumiram 20% menos ração que animais consumindo DB. O consumo de silagem diário foi diferente entre os tipos de silagem fornecida. O consumo de água foi menor nos animais alimentados com silagem. O ganho médio diário não diferiu, sendo de 33 g, 38 g, e 34 g respectivamente para os animais alimentados com DB, SG e SM. Ocorreu redução no custo da alimentação utilizando silagem na dieta de coelhos. Os coelhos que foram alimentados com SM apresentaram melhor viabilidade econômica.

The Impact

The aim of this study is to investigate the impact of immersion time, at different time values for two cases, with stressed and no stressed on materials. This study is conducted using SUS304 material with the presence of 3.5% NaCl at the range of stresses for the specimens lower than the yield strength.  The geometry of the C-ring specimen was selected for 18.974 mm and 1.244 mm for the outer diameters and the thickness respectively. The immersion time effect was investigated using the half-cell potential measurement following the ASTM G-38 standard. The approach of corrosion environment was applied to resemble the condition of loading history. Three levels of stresses were designed and applied in finite element analysis and the results known as the parameters of stress-corrosion measurement. The ASTM G-38 standard is prominent for making C-ring stress-corrosion for elastic stress analysis. The stress-corrosion test was performed at two parameters, fixed stress and no stress. The value of stresses for fixed stress was chosen for 179.199 MPa, 328.665 MPa and 460.131 MPa, correspondingly. The immersion time were selected from 0, 10 and 30 days. The electrochemical result shows that the immersion time did not affect vastly to the corrosion behavior for no stress-corrosion compared with fixed stress. The corrosion rate increases proportionally with the time immersion increments due to the inability of the steel layer protection to regenerate itself. Subsequently, it is also due to the metal was exposed to plastic deformation that resulting the internal stresses due to the plastic anisotropy of the grains.

Adipose Tissue Development

SummaryA nutritionally induced obesity model was used to investigate the modulation of fibrinolytic and gelatinolytic activity during the development of adipose tissue.Five week old male mice were fed a standard fat diet (SFD, 13% kcal as fat) or a high fat diet (HFD, 42% kcal as fat) for up to 15 weeks. The HFD resulted in body weights of 31 ± 0.9 g, 38 ± 2.0 g and 47 ± 1.9 g at 5, 10 and 15 weeks, respectively; corresponding values for mice on the SFD were 26 ± 0.6 g, 31 ± 0.9 g and 31 ± 1.2 g (all p < 0.001). The weight of the isolated subcutaneous (SC) or gonadal (GON) fat after 15 weeks of HFD was 1,870 ± 180 mg or 1,470 ± 160 mg, as compared to 250 ± 58 mg or 350 ± 71 mg for the SFD (p < 0.001). The HFD induced marked time-dependent hyperglycemia and elevated levels of triglycerides and total cholesterol. The HFD diet also induced a marked hypertrophy of the adipocytes as compared to the SFD, e.g. diameter of 83 ± 3.0 µm versus 52 ± 4.2 µm for GON adipocytes at 15 weeks (p < 0.005). Plasma plasminogen activator inhibitor-1 (PAI-1) levels were higher in mice on the HFD as compared to the SFD; they were comparable in extracts of SC or GON adipose tissue, whereas at different time points tissue-type (t-PA) and urokinase-type (u-PA) plasminogen activator activity was somewhat lower in the adipose tissues of mice on HFD. Gelatinolytic activity (mainly MMP-2) was detected in SC but not in GON adipose tissue of mice on SFD, and decreased on the HFD. In situ zymography on cryosections did not reveal different fibrinolytic activities in SC or GON adipose tissues of the HFD as compared to the SFD groups, whereas significantly lower gelatinolytic and higher caseinolytic activities were detected in SC and GON tissues of mice on the HFD (p ≤ 0.05). The fibrillar collagen content was lower in adipose tissue of mice on HFD. Thus, in this model time-dependent development of adipose tissue appears to be associated with modulation of proteolytic activity.

Number Of Particles

Particle Size Distribution (PSD) in highway runoff was monitored in the 2004–2005 rainy season at three highway sites in west Los Angeles, California. PSD was measured for 200 grab samples for 18 storm events. Particles and especially larger particles showed a strong first flush. On average, the initial 20% runoff volume transported approximately 28% total number of particles between 0.5 and 2 μm in diameter, more than 30% of particles between 2 and 30 μm and more than 40% of particles larger than 30 μm. A naturally occurring aggregation was observed with smaller particles and mixing experiments were performed to determine the possible benefits for sedimentation and filtration. Samples composited from grab samples manually collected over the first hour of runoff were gently mixed (G = 38) and small particle concentration decreased by more than 50%. After 24 hours the number of particles with diameter between 0.5 and 7 μm decreased by 51% with gentle mixing and the same size particles decreased by only 14% without mixing. Number of particles with diameter larger than 20 μm increased by 6 and 4.5 times with and without mixing, respectively. Slow mixing can improve sedimentation efficiency by more than 40% for particles less than 20 μm in diameter.

Disadvantaged Families

Purpose: To examine the effects of short-term psychological interventions on reducing family stress of economically disadvantaged families. Method: Systematic review and meta-analytic procedures were used to synthesize the results of randomized controlled studies published between 1980 and 2018. Results: The search yielded 8 studies that included results for 1,538 families in total. The risk of bias varied across studies. The meta-analysis results suggest a small positive effect ( g = .38, p < .001) on child behavioral problems. Heterogeneity was relatively high and significant. We also found small to moderate effects on parenting stress, parental depression, and parenting quality ( g ranging from .30 to .51). Discussion: The findings of this review suggest that short-term psychological interventions may reduce the family stress of economically disadvantaged families, with effect sizes that are comparable to those of interventions delivered to ordinary families. Implications for further research and practice are discussed.

AbstractAn experiment was undertaken to compare the carcass characteristics and meat quality of lambs from crossbred ewes produced by crossing Texel sires with Rouge de l’Ouest dams and Rouge sires with Texel dams, relative to lambs from purebred Texel and Rouge ewes. The ewes were crossed with Texel or Rouge sires and the relative performance of the sires assessed in terms of lamb carcass quality. Ewe and ram genotype had a significant effect on conformation classification. Lambs from Texel ewes had a greater conformation classification (4·0) than lambs from Rouge ewes (3·4, s.e. 0·09) (P<0·001) and Texel-sired lambs had a greater conformation classification (4·0) than Rouge-sired lambs (3·6, s.e. 0·06) (P<0·001). Fat depth was significantly influenced by ewe genotype with lambs from Texel × Rouge ewes having greater fat depths compared with lambs from Texel ewes (longissimus dorsi 2·3 and 1·9 (s.e.0·12) mm respectively) (P<0·05). Chemical composition of the carcass and meat quality measurements were unaffected by ewe or ram genotype. Significant heterosis effects on lamb live-weight gain (21 g/day; 15%) (P<0·01) from birth to slaughter, age at slaughter (–37 days; –12%) (P<0·01), weight of perinephric and retroperitoneal fat (76 g; 38%) (P<0·01) and fat depth over the longissimus dorsi (0·3 mm; 16%) and gluteus medius (0·5 mm; 17%;P<0·05) were obtained. The results from this study demonstrate that significant heterosis effects, particularly in terms of lamb growth rate, can be achieved by crossing Rouge and Texel breeds. In addition lambs from hybrid ewes have similar conformation characteristics to the Texel breed which has been intensively selected for carcass characteristics.
