Desempenho e análise econômica de coelhos cruzados em crescimento suplementados com silagem de milho ou silagem de girassol

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.

Sterol and Mineral Profiles of the Common Sea Snail Hinia Reticulata and the Long Sea Snail Nassarius Mutabilis (Gastropods) Collected from the Middle Adriatic Sea

Sea snails represent a common food in the world as a source of sterols, such as cholesterol and phytosterol, and minerals. Sterols play important roles in body functions and also minerals are important for human health, so the intake of these nutrients into human diets should be known. The aim of this study was to examine the sterol and mineral profiles of the long (Hinia reticulata) and the common (Nassarius mutabilis) sea snails. Samples of both species were collected at different catch times from November 2019 to March 2020 and transported to the University of Camerino (UNICAM) for the evaluation of their sterol and mineral profiles, including toxic elements (Cd, Cr, Pb). The results of the study showed that the average content of total lipid were 57 mg/100 g, 38 mg/100 g for cholesterol and 19 mg/100 g for phytosterol in the long sea snail, and the values were respectively 68, 48, and 20 mg/100 g in the common sea snail, without significant differences in the two examined sea snails. Additionally, the result of the mineral analysis showed that both species were significant sources of minerals, with negligible levels of toxic metals and metalloids. Therefore, the Long and the Common sea snail are suitable and safety sea products for human nutrition.

Search for neutrinoless double beta decay of $$^{64}$$Zn and $$^{70}$$Zn with CUPID-0

CUPID-0 is the first pilot experiment of CUPID, a next-generation project searching for neutrinoless double beta decay. In its first scientific run, CUPID-0 operated 26 ZnSe cryogenic calorimeters coupled to light detectors in the underground Laboratori Nazionali del Gran Sasso. In this work, we analyzed a ZnSe exposure of 11.34 kg year to search for the neutrinoless double beta decay of $$^{70}$$70Zn and for the neutrinoless positron-emitting electron capture of $$^{64}$$64Zn. We found no evidence for these decays and set 90$$\%$$% credible interval limits of $$\hbox {T}_{1/2}^{0\nu \beta \beta }$$T1/20νββ($$^{70}$$70Zn) > 1.6 $$10^{21}$$1021 year and $$\hbox {T}_{1/2}^{0\nu EC \beta +}$$T1/20νECβ+($$^{64}$$64Zn) > 1.2$$\times 10^{22}$$×1022 year, surpassing by more than one order of magnitude the previous experimental results (Belli et al. in J Phys G 38(11):115107, https://doi.org/10.1088/0954-3899/38/11/115107, 2011).

Short-Term Psychological Interventions on Economically Disadvantaged Families: A Systematic Review and Meta-Analysis

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.

Rumination, Suicidal Ideation, and Suicide Attempts: A Meta-Analytic Review

Rumination has been implicated as a risk factor for suicidal ideation and attempts, yet the literature to date has not been synthesized. We conducted a meta-analysis of the association between rumination and both suicidal ideation and attempts to consolidate the existing literature ( k = 29). Results indicated that the relationships between global rumination ( k = 13; Hedge's g = .74, p < .001, 95% CI [.45, 1.04]), brooding ( k = 12; Hedge's g = .63, p < .001, 95% CI [.35, .90]), and reflection ( k = 12; Hedge's g = .38, p = .002, 95% CI [.10, .65]) with suicidal ideation were significant. Associations between global rumination ( k = 3; Hedge's g = .26, p < .001, 95% CI [.08, .44]) and brooding ( k = 4; Hedge's g = .47, p = .004, 95% CI [.02, .91]) and suicide attempts were significant, but reflection ( k = 4; Hedge's g = .09, p = .646, 95% CI [−.54, .72]) was unrelated. However, given the limited studies included in suicide attempt analyses—and the exclusive use of cross-sectional designs and heterogeneity with regard to samples and measures—these parameters should be taken with caution. Generally, age, gender, race/ethnicity, and year of publication were not moderators, and there was little evidence for publication bias across effects, with the exception of the effect of global rumination on suicidal ideation. Several future research directions are discussed.

THE EFFECT OF IMMERSION TIME ON THE CORROSION BEHAVIOR OF SUS304 IN BRINE USING HALF-CELL POTENTIAL MEASUREMENT

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.

Variability and heritability analysis in spring wheat (Triricum aestivum L .) Genotypes

The experiment was carried out with 50 wheat lines to study their intergenotypic variability, heritability, GCV, PCV, genetic advance, and CV percent considering 14 morphological characters at the experimental field of Regional Wheat Research Centre RWRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during November 2010 to March 2010. Significant variation was observed among the genotypes for all characters studied. High GCV and PCV values were observed for grain filling duration, grain filling rate, and seed yield. High heritability along with higher genetic advance was observed for DTH, DTA, DPM, GFD, GFR, PHT, CHLA, spikelets/spk., and yield kg/ha. The remaining traits showed lower heritability coupled with low genetic advance in percent of mean. Considering variability among the genotypes, heritability, genetic advance, percent co-efficient of variation, and field performances, the genotypes G 3, G 10, G 11, G 12, G13, G 21, G 29, G 35, G 38, G 40, G 46 and G 48 were found suitable for future breeding programme.Bangladesh J.

UNIVERSITETINĖS LEIDYBOS PROCESO SISTEMA: SANDARA IR JOS ELEMENTAI

Vilniaus universiteto Knygotyros ir dokumentotyros institutasUniversiteto g. 3, LT-01513 Vilnius, LietuvaEl. paštas: [email protected]Šiaulių universiteto Lietuvių kalbotyros ir komunikacijos katedraP. Višinskio g. 38, LT-76352 Šiauliai, LietuvaEl. paštas: [email protected] nagrinėjama Lietuvos universitetinės leidybos proceso sandara ir jos elementai, išskiriant konkrečius leidybos etapus kaip vientisą ir nenutrūkstamą universitetinės leidybos darbo ir veiklos procesą. Universitetinėse leidyklose įvairių leidinių tipų rengimas publikuoti susideda iš dviejų pagrindinių etapų: 1) ikileidybinės parengties etapo, kuriame leidinys aprobuojamas mokslinės komisijos kaip tinkamas leidybai ir 2) leidybinės parengties etapo, kuriame leidinys perduodamas leidyklai ir ten rengiamas publikuoti. Vienas svarbiausių ikileidybinės parengties etapo elementų yra leidinio aprobacija akademinės institucijos struktūriniuose padaliniuose, padedanti išlaikyti aukštą universitetinės leidyklos publikuojamų mokslo ir studijų leidinių turinio kokybę. Tolesni aprobuotos ir atiduotos į leidyklą knygos leidybinės parengties etapai yra bendri – leidinys redaguojamas, koreguojamas ir maketuojamas. Taigi universitetinės leidybos proceso sandara ir jos elementai (veiksmai) – ikileidybinės ir leidybinės parengties etapai – traktuotini kaip vientisa ir nenutrūkstama leidybos proceso sistema. Straipsnyje prieita prie išvados, kad bendroji universitetinės leidybos proceso sistema yra tipinė ir tinka visoms akademinėms mūsų šalies institucijoms. Tačiau ši sistema, nors ir būdama vientisa ir nenutrūkstama, vis dar nėra pakankamai išplėtota dėl ilgai trunkančių ikileidybinės ir leidybinės parengties etapų.
