title: Germination, viability and longevity of horseweed (Conyza spp.) seeds as a function of temperature and evaluation periods

description: ABSTRACT: In Brazil, horseweed is one of the most important weeds because of the resistance to herbicides and high competitive for the crops. A large of losses were reported in major crops such as soybeans, wheat and corn, where the use a no-tillage system and the herbicide resistance promote better establishment. A correct understanding of the way temperature influences germination enables the prediction of the regions with the highest potential for colonization by this weed and thus facilitates its control. The objective of this study; therefore, was to discern the ways temperature affected the germination, viability and longevity of horseweed seeds. Testing was done at 10, 20 and 30°C, while evaluation occurred on days 0, 15, 30, 45 and 60. Seeds were packed in a nylon mesh bag (5x5cm), with 10g of upland soil (Yellow Red Argissolo, sandy loam texture), placed in transparent plastic boxes at 0 to 0.5cm soil depth, at the temperatures specified. Percentage of remaining seeds, first and second germination counts, abnormal seedlings, and dead, dormant, viable and non-viable seeds, were assessed. Horseweed seeds achieve secondary dormancy at 10, 20 and 30°C, while their quality and the longevity showed damage at 20 and 30°C temperatures.

title: Assessment of professional competence of nurses in emergencies: created and validated instrument

description: ABSTRACT Objective: To create an instrument to assess the professional competence of nurses in emergencies. Method: Methodological study carried out between 2013 and 2016 in a Brazilian university. We used the Pasquali's model and Psychometrics as references because they allow subjective phenomena to be measured. The survey covered defining steps of the behavior to be measured, the formulation of the items in the instrument, development of instructions for using the instrument and elements necessary to demonstrate validity evidence. Although we have previously performed, in a distinct and consecutive way, the literature review, definition of the Core (or Matrix) Competence and the Competence Profile, and identification of validity with Delphi, essential components to structure a technology, in this step we continued the conclusion of these Theoretical Procedures. Result: We created an instrument for self- and/or hetero-evaluation containing: personal/professional/academic characterization, Competency Scale, fictitious cases and actions representing the practice. Conclusion: We created a new soft-hard technology based on the validity evidence of contents according to experts of the five regions of Brazil.

title: Weed interference in the initial growth of meristem-grown sugarcane plantlets

description: ABSTRACT The use of new systems of sugarcane planting such as PleneTM, Plene EvolveTM, Plene PBTM and AgMusaTM requires specific studies on the initial interference of weed in the sugarcane crop. The objective of this study was to evaluate initial weed interference in meristem-grown sugarcane plantlets (Plene EvolveTM). The weed species used were Brachiaria decumbens and Panicum maximum, at four different densities (1, 2, 3 and 4 weed plants pot-1), plus a control treatment free from weed interference. The statistical design was completely randomized with four replicates per treatment, with an individual study for each weed species. The evaluations performed were: plant height at 45, 60 and 90 days after emergence (DAE), number of sugarcane tillers at 30, 60 and 90 DAE and dry matter of both sugarcane and weed plants at 90 DAE. B. decumbens and P. maximum caused reductions in the initial growth and development of sugarcane. P. maximum was more aggressive to meristem-grown sugarcane plants, during their early development, than B. decumbens.

title: Protein beverages containing anthocyanins of jabuticaba

description: Abstract The objective of this study was to develop, characterize and evaluate the stability of whey protein beverages containing anthocyanins from jabuticaba skins. Beverage formulations containing 0.5% (F1), 2.0% (F2), 4.0% (F3) and 6.0% (F4) of whey proteins and 2.0 mL of the concentrated phenolic extract from jabuticaba skins were developed. Physicochemical parameters (pH, acidity, total soluble solids, protein content, viscosity, color), antioxidant capacity, total anthocyanins and total phenols of the beverages were determined. In addition, a sensory acceptance test and a stability study were performed. The physicochemical analyses indicated that the protein concentration significantly (p &lt; 0.05) affected the values of acidity, total soluble solids, total phenols and antioxidant capacity. The protein content also influenced the total color difference (ΔE) between formulations. The greater differences were observed in the formulation pairs containing low and high protein contents. The formulations F1, F2 and F3 were equally accepted on overall impression and color attributes. The stability study demonstrated that there was no significant change (p &gt; 0.05) in the total anthocyanins and in the physicochemical properties of F3 over storage time, which indicated a good stability and a great market potential of the whey protein beverages containing anthocyanins from jabuticaba skins.

title: Optimization of ultrasound-assisted extraction of procyanidins from perilla seed hull and their antioxidant activities in vitro

description: Abstract Ultrasound-assisted extraction (UAE) was used to extract procyanidins (PC) from the perilla seed hull. Four independent variables, namely, liquid-to-solid ratio, ethanol concentration, UAE time, and UAE temperature were investigated. Response surface methodology was performed on the basis of results of single-factor tests. The optimal conditions for PC extraction were as follows: a liquid-to-solid ratio of 15:1, an ethanol concentration of 62%, a UAE time of 29 min, and a UAE temperature of 53 °C. Under these conditions, the experimental yield of PC was 2.185 mg/g (n = 3), which is correlated with the predicted value of 2.2 mg/g. The extracted and purified PC showed excellent antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl, hydroxyl, and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radicals in vitro.

title: Performance, fatty acids profile and oxidative stability of meat of rabbits fed different lipid sources

description: Abstract To evaluate the use of different lipid sources in diets of growing rabbits, 60 New Zealand White rabbits were evaluated on performance, carcass traits, meat composition, fatty acid profile and oxidative stability of refrigerated and frozen meat. The experiment was distributed in a randomized block design, in five treatments, with six replicates and two animals per experimental unit (one male and one female). The treatments consisted of five isonutritive diets, with 2.5% soybean oil (SO), sunflower oil (SFO), cottonseed oil (CO), beef tallow (BT) and poultry fat (PF). There was no effect (P &gt; 0.05) of dietary lipid sources on animal performance, carcass traits and meat composition (P &gt; 0.05). Dietary inclusion of beef tallow resulted in a lower proportion of polyunsaturated fatty acids in meat compared to vegetable oils. The values of thiobarbituric acid-reactive substances (TBARS) indicated higher oxidation in the frozen meat of the animals fed with sunflower oil, cottonseed oil and bovine tallow in their diets. In conclusion, vegetable oils and animal fats can be included in growing rabbit diets without impair performance and meat quality parameters. Dietary inclusion of soybean oil is more advantageous because it promotes the incorporation of polyunsaturated fatty acids and greater lipid stability of refrigerated and frozen rabbit meat.

title: The effects of different feeding times and diets on the whole body fatty acid composition of goldfish (Carassius auratus) larvae

description: Abstract In this study, the effects on whole body fatty acid levels of goldfish larvae (Carassius auratus) caused by different feeding times T(1–4) and diets D(1–3) were investigated during the early larval stages which is the first 15 days’ of feeding. Fatty acid levels for all experimental groups were found to be: 1.54 to 3.45% for myristic acid, 17.57 to 22.68% for palmitic acid, 28.81 to 41.16% for total saturated fatty acids-∑SFA, 2.37 to 4.04% for palmitoleic acid, 13.79 to 39.21% for oleic acid, 22.60 to 47.59% for total monounsaturated fatty acids-∑MUFA, 3.62 to 7.69% for linolenic acid-ALA, 0.35 to 1.11% for arachidonic acid-ARA, 7.50 to 9.76% for total n-6 fatty acids-∑ n-6, 1.04 to 2.28% for linoleic acid-LA, 0.81 to 2.52% for eicosapentaenoic acid-EPA and 5.56 to 10.28% for docosahexaenoic acid-DHA. The total n-3 acids-∑ n-3, total polyunsaturated fatty acids-∑PUFA, PUFA/SFA ratio, ∑ n-6/∑ n-3 and DHA/EPA ratio of the experimental groups were determined to be 7.24 to 14.83%, 14.73 to 23.46%, 0.47 to 0.73, 0.58 to 1.04 and 3.21 to 8.7, respectively. In conclusion, the whole body fatty acid levels of goldfish larvae (Carassius auratus) determined in this study revealed the significant effects of different feeding times (T1–4) and different diets (D 1–3) using (P &lt; 0.05).

title: Effects of Modified Atmosphere Packaging (MAP) and slaughter age on the shelf life of lamb meat

description: Abstract The shelf life extending effect of different modified atmospheres packages (MAP): vacuum (MAP-1), 69.6% N2 + 30% CO2 + 0.4% CO (MAP-2) and 70% O2 + 30% CO2 (MAP-3) on lamb meat at two slaughter ages (4 and 8-month-old) was assessed. pH decreased as slaughter age (SA) increased, and increased during longer storage time (ST), with no MAP effects. Lamb meat stored in MAP-1 and MAP-3 showed greater drip loss than that stored in MAP-2. Shear force was not influenced by SA and MAP treatments, but decreased during ST. Meat from 8-month-old lambs packaged in MAP-3 at longer ST resulted in lipid oxidation increase. MAP-2 enhanced color saturation and lamb meat redness, whereas MAP-3 showed lowest redness and chroma values, and highest aerobic psychrotropic count. Meat from 4-month-old lamb stored in MAP-3 presented shortest shelf life based on psychrotropic bacteria growth. The association of higher SA with high O2 MAP proved to compromise oxidative stability of lamb meat, adversely affecting its shelf life. Vacuum and CO packaging showed similar effects on lamb meat preservation; however, CO had advantage in maintaining fresh red color of meat.

title: Chemical characterization of winemaking byproducts from grape varieties cultivated in Vale do São Francisco, Brazil

description: Abstract The recovery of agroindustry byproducts can bring opportunities for the development of new products. The objective of this study was to characterize chemical compounds contents in the byproducts generated during winemaking from different grape varieties cultivated in Vale do São Francisco, Brazil. The grapes and their byproducts (skins and seeds) from four wineries (w1, w2, w3 and w4) were evaluated. The varieties studied were: Viognier, Chenin Blanc, Moscato Canelli, Italia, Arinto+Fernão Pires, Tempranillo, Grenache, Mourvèdre, Verdejo and Sauvignon Blanc, used in the processing of white/sparkling wines, and also Tempranillo, Cabernet Sauvignon, Syrah and Alicante Bouschet, used in the processing of red wines. High ascorbic acid contents were found in the skin and seed byproducts, the latter also presenting high protein and pectin contents. The skin byproduct obtained in the process of elaborating white/sparkling wines from ‘Tempranillo’ grapes presented relatively higher ascorbic acid, pectin and protein contents. In the elaboration of red wines by w1, the ‘Syrah’ skin byproduct showed high ascorbic acid, soluble solids, sugars and protein contents. The seed byproduct from the ‘Syrah’ grapes used to elaborate red wines by w1 showed a more favorable composition for reuse, as did those of red wines of ‘Tempranillo’ grapes from w3.

title: THE GROWING SPACE UTILIZATION OF MAIN TREE SPECIES IN NORTHERN TURKEY

description: ABSTRACT Relationships between tree size and density are important to define the growing space utilization in a stand. Although a universal slope for the maximum size-density relationships (MSDRs) has been previously suggested, recent research have highlighted that these relationships are species-specific. Oriental beech (Fagus orientalis Lipsky), Trojan fir (Abies nordmanniana subsp.equi-trojani), black pine (Pinus nigra Arnold) and Scots pine (Pinus sylvestris L.) represent different crown architecture, growth rate and shade tolerance; however, MSDRs have not been developed for these tree species in northern Turkey. In this study, average maximum density (DAM) slopes for these tree species were determined. Results suggested that MSDRs varied among the species, and that their slope differed from the universal slope of -1.605. The MSDRs described in this study are useful for managing stand density in natural stands of the species analyzed.
