Band gaps in the relaxed linear micromorphic continuum

In this note we show that the relaxed linear micromorphic model recently proposed by the authors can be suitably used to describe the presence of band-gaps in metamaterials with microstructures in which strong contrasts of the mechanical properties are present (e.g. phononic crystals and lattice structures). This relaxed micromorphic model only has 6 constitutive parameters instead of 18 parameters needed in Mindlin- and Eringen-type classical micromorphic models. We show that the onset of band-gaps is related to a unique constitutive parameter, the Cosserat couple modulus $\mu_{c}$ which starts to account for band-gaps when reaching a suitable threshold value. The limited number of parameters of our model, as well as the specific effect of some of them on wave propagation can be seen as an important step towards indirect measurement campaigns

Endocrine and metabolic traits in goat kids around weaning

Eleven Saanen kids, three days after birth, were divided into two groups: WEAN and MILK. All kids were fed goat milk until the 5th week of age, when the WEAN group began a weaning protocol. MILK group continued to receive goat milk for the entire experimental period, while WEAN group was weaned at 47 days of age. Starting from the 3rd week of age, body weight was recorded and blood samples were taken weekly, before the first meal of the day. Plasma was analysed for glucose, total protein, free aminoacid, insulin, leptin and ghrelin.Weaning did not affect plasma levels of total protein and leptin, but decreased plasma glucose and free aminoacid, and increased ghrelin concentration. Moreover, weaning decreased plasma insulin level more than three times. This result was probably the consequence of the lower concentration of plasma glucose of the WEAN group, but the effect could be enforced by the milk-borne insulin ingested by the MILK kids with the diet. Goat milk contains peptides that can pass across the intestinal epithelium and enter the systemic circulation, suggesting a possible role in accomplishing the immature ability of suckling animals to produce hormones and growth factors

Localization of the genes controlling B chromosome transmission rate in maize (Zea mays ssp. mays, Poaceae)

In previous papers we found that the frequency of B chromosomes in native races of maize varies considerably in different populations. Moreover, we found genotypes that control high and low transmission rates (TR) of B chromosomes in the Pisingallo race. In the present work crosses were made to determine whether the genes controlling B-TR are located on the normal chromosome set (As) or on the B chromosomes (Bs). We made female f.0B x male m.2B crosses between and within high (H) and low (L) B-TR groups. The Bs were transmitted on the male side in all cases. The mean B-TR from the progeny of f.0B (H) x m.2B (H) and f.0B (H) x m.2B (L) crosses was significantly higher than that from f.0B (L) x m.2B (L) and f.0B (L) x m.2B (H) crosses. The results show that the B-TR of the crosses corresponds to the H or L B-TR of the 0B female parents irrespective of the Bs of the male parent. This indicates that B-TR is genetically controlled by the 0B female parent and that these genes are located on the A chromosomes.Fil:Chiavarino, A.M. Universidad de Buenos Aires.

Microfiltration and ultra-high-pressure homogenization for extending the shelf-storage stability of UHT milk

Fat separation, gelation or sedimentation of UHT milk during shelf-storage represent instability phenomena causing the product rejection by consumers. Stability of UHT milk is of increasing concern because access to emerging markets currently implies for this product to be stable during shipping and prolonged storage, up to 12 months. The role of microfiltration prior to UHT process in avoiding or retarding the gelation or sediment formation was studied by comparing microfiltered UHT milk to conventional UHT milk. A second trial was set up to study the effects of double ultra-high pressure homogenization in delaying the cream rising and UHT milk homogenized once at lower pressure was taken as control. All milk samples were produced at industrial plant level. Milk packages were stored at 22 \ub0C, opened monthly for visually inspecting the presence of cream layer, gel or sediment and then analysed. Microfiltration markedly delayed the formation of both gel particles and sediment, with respect to the control, and slowed down the proteolysis in terms of accumulation of peptides although no correlation was observed between the two phenomena. The double homogenization, also evaluated at ultra-structural level, narrowed the fat globule distribution and the second one (400 MPa), performed downstream to the sterilization step, disrupted the fat-protein aggregates produced in the first one (250 MPa). The adopted conditions avoided the appearance of the cream layer in the UHT milk up to 18 months. This study contributes important knowledge for developing strategies to delay instability phenomena in UHT milk destined to extremely long shelf storage

Changes in the soluble nitrogen fraction of milk throughout PDO Grana Padano cheese-making

The behaviour of soluble nitrogen compounds during Grana Padano cheese-making was studied at eight dairies. Raw milk, skimmed milk, sweet whey and the derived natural whey culture, collected from 24 processes, were analysed for soluble whey proteins (\u3b1-lactalbumin and \u3b2-lactoglobulin), proteose-peptones (PP), small peptides (SP), caseinomacropeptides (CMPs), and free amino acids (FAAs). The PP fraction increased during milk natural creaming, then part of it was selectively retained in the curd and the rest degraded in the first few hours of whey fermentation, together with \u3b1-lactalbumin, CMPs and part of SP. Features outlined for the whey culture were confirmed on 30 samples collected at six different dairies. A time course study of the whey fermentation showed that degradation of \u3b1-lactalbumin began when the pH dropped below 4, whereas \u3b2-lactoglobulin content did not change. Uptake of specific FAAs was shown to support the initial growth of lactic acid bacteria in whey

Health Belief Model on the Factors Associated with the Use of HPV Vaccine for the Prevention of Cervical Cancer Among Women in Kediri, East Java

Background: Cervical cancer is a deadly disease with high incidence rates in the world and in Indonesia. In Kediri, East Java, there were 33 women who had cervical cancer in 2016, 3 of them died. Cervical cancer is caused by type 16 and type 18 Human Papilloma Viruses (HPV). This disease can be prevented by the application of HPV vaccine. This study aimed to examine factors associated with the use of HPV vaccine for the prevention of cervical cancer among women in Kediri, East Java, using health belief model (HBM).Subjects and Method: This study was an analytic observational with case control design. It was conducted in Kediri, East Java, from February 10 to March 10, 2017. A sample of 120 women consisting of 40 women who had used HPV vaccine and 80 women who had not used HPV vaccine, were selected for this study by fixed disease sampling. The dependent variable was use of HPV vaccine. The independent variables included perceived susceptibility, perceived severity, perceived benefit, perceived threat, perceived barrier, and cues to action. The data were collected by a set of pre-tested questionnaire. Logistic regression was employed for data analysis.Results: The use of HPV vaccine was associated with perceived susceptibility (OR= 0.79; 95% CI= 0.23 to 2.70; p= 0.710), perceived severity (OR= 5.19; 95% CI= 1.30 to 20.66; p= 0.019), perceived threat (OR= 1.04; 95% CI= 0.32 to 3.35; p= 0.942), perceived benefit (OR= 1.33; 95% CI= 0.40 to 4.38; p= 0.638), perceived barrier (OR= 0.42; 95% CI= 0.14 to 1.27; p= 0.126), and cues to action (OR= 5.90; 95% CI= 1.30 to 26.74; p = 0.021).Conclusion: The use of HPV vaccine is associated with perceived susceptibility, perceived severity, perceived threat, perceived benefit, perceived barrier, and cues to action. Constructs in health belief model can be used to predict the use of HPV vaccine.Keywords: health belief model, use of HPV vaccineCorrespondence: Rosi Rizqi Nugrahani.
