Honey bees, rather than rear queens with eggs and larvae from worker cells, prefer to rear new queens with eggs form queen cells, if available. This may be a result of long-term evolutionary process for honey bee colonies. However, the exact mechanism of this phenomenon is unclear. In this study, queens were reared with eggs from queen cells (F1-QE), eggs from worker cells (F1-WE), and two-day-old larvae from worker cells (F1-2L). Physiological indexes and the expression of the development-related genes ((Hexamerin (Hex110, Hex70b), Transferrin (Trf), and Vitellogenin (Vg)) of reared F1 generation queens were measured and compared. Furthermore, F2 generation queens were reared with one-day-old larvae from F1 queens, and the weight and ovariole count of reared F2 generation daughter queens were examined. Meanwhile, the expression of the development- and reproduction-related genes (Hex110, Hex70b, Trf, Vg, and Juvenile Hormone (Jh)) and immune detoxication-related genes (Hymenoptaecin, Abeacin, and CytP450) of reared F2 queens were further explored. We found that the F1-QE queens had the highest physiological indexes and higher Hex110 and Trf expression levels, while no significant difference was found in the expression of Hex70b and Vg among the three groups of F1 queens. In addition, the reared queens of F2-QE had the highest quality, with the highest development, reproduction, immune-detoxication genes’ expression levels. Our results revealed that the quality of reared offspring queens from high-quality mother queens was also high. These findings inform methods for rearing high-quality queens and highlight that a high-quality queen is essential for offspring colony growth and survival.

Abstract This study aims to investigate the effect of queen cell size (9.4 mm, 9.6 mm, 9.8 mm and 10.0 mm) and mother queen caged time (0 day, 2 days and 4 days) on rearing young queens without grafting larvae. The birth weight, ovarian tubes, thorax length and width were significantly increased with the increasing diameter of queen cell size. The expression level of Vitellogenin (Vg) in young queen ovaries was also up-regulated with the increased queen cell size diameter. These results indicate that the queen cell size can strongly affect the rearing queen quality and reproductive ability. Moreover, the weight, length and width of laying eggs rose with the mother queen caging time, and young queens reared with the hatched larvae from these eggs were also increased in terms of birth weight, ovarian tubes, thorax length and width. Furthermore, the expression level of Vg in reared queen ovaries was also up-regulated with the caged time. These results reveal that the caged time of queens could significantly influence egg size and their relative queen quality.

Full textAbstract:
Failure of the queen is often identified as a leading cause of honey bee colony mortality. However, the factors that can contribute to “queen failure” are poorly defined and often misunderstood. We studied one specific sign attributed to queen failure: poor brood pattern. In 2016 and 2017, we identified pairs of colonies with “good” and “poor” brood patterns in commercial beekeeping operations and used standard metrics to assess queen and colony health. We found no queen quality measures reliably associated with poor-brood colonies. In the second year (2017), we exchanged queens between colony pairs (n = 21): a queen from a poor-brood colony was introduced into a good-brood colony and vice versa. We observed that brood patterns of queens originally from poor-brood colonies significantly improved after placement into a good-brood colony after 21 days, suggesting factors other than the queen contributed to brood pattern. Our study challenges the notion that brood pattern alone is sufficient to judge queen quality. Our results emphasize the challenges in determining the root source for problems related to the queen when assessing honey bee colony health.

The basic rule in honeybee (Apis mellifera L.) rearing is to work with qualified queens. Quality queen means strong and healthy colonies. Honey bee colonies are a social community, each managed by a single queen bee. The queen bee is the only female that produces eggs in the colony under normal conditions, and the quality and healthy queen is important for the continuity of the colony. Many factors affect the quality of the queen bee, such as the rearing colony, the age of the transferred larva and the transfer medium, the season, cell emergence weight, spermatheca charged, the characteristics of the starter and finisher hives. In this paper, the issues to be considered in raising a quality queen are emphasized.

Effects of the Age of Grafted Larvae and the Effects of Supplemental Feeding on Some Morphological Characteristics of Iranian Queen Honey Bees (Apis mellifera medaSkorikov, 1929)The research was conducted at the apiary of the Faculty of Agriculture, Zanjan University in Zanjan, Iran. Queens were reared in 24Apis mellifera medahoney bee rearing colonies. The colonies were assigned to 4 grafting larvae age groups; 1 day old larvae, 2 day old larvae, and 3 day old larvae, and the last group reared emergency queen cells. The groups were divided into the 2 feeding groups: fed additionally and no fed. The effects of the age of the grafted larvae and the effects of supplemental feeding on 9 morphological characteristics of queens were measured. The results showed that the age of the larvae significantly affected the morphological characteristics of reared queens, and thus, their quality. Queens reared from 1 day old larvae were of the highest quality. These queens were significantly heavier (158.83 mg) and had significantly larger spermatheca (0.99 mm3) than queens reared from larvae 2 and 3 days old. Queens from emergency queen cells were of lower quality than queens reared from 1 day old larvae. However, queens from emergency queen cells were of higher quality than queens reared from 3 day old larvae. The supplemental feeding significantly increased most morphological characteristics of the reared queens. The different ages of the larvae did not significantly affect the wing length nor did supplemental feeding affect the wing length.

AbstractIn this three-year-trial study, we examined the quality of mated queens based on morphological and physiology traits. At each location, sister queen bees were reared each year from one Apis mellifera carnica breeder queen. Queens were also reared and mated in different locations. Altogether, we sampled and analysed 324 queens from 27 apiaries in 2006, 288 queens from 24 apiaries in 2008, and 276 queens from 23 apiaries in 2010. Nine queens from each apiary were sampled and dissected for morphological analyses and Nosema ceranae (N. ceranae) spores, if present, were quantified. Three queens from each apiary were prepared and tested for four viruses: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), deformed wing virus (DWV), and sacbrood virus (SBV). The highest average queen weight of 209.49 ± 9.82 mg was detected in 2008. The highest average ovary weight of 78.67 ± 11.86 mg was detected in 2010, and the highest number of ovarioles was 161.59 ± 8.70 in 2006. The average number of spermatozoa in queens ranged from 3.30 x 106 in 2006 to 5.23 x 106 in 2010. Nosema ceranae spores were found in queens sampled in 2008 and 2010. Viruses were discovered sporadically during the queen testing periods from 2006 - 2010. This study importantly demonstrates that queens from rearing stations require regular evaluation for morphological and physiological changes as well as for infection from harmful pathogens. These results could also be used in establishing relevant commercial standards for rearing quality queens.

Viral infection could have an impact on the success of queen rearing and a potential effect on reduced queen quality. Newly mated honey bee (Apis mellifera carnica) queens were collected from mating nuclei in queen rearing operations in Slovenia. Altogether, 81 queens were sampled from 27 rearing apiaries in 2006 and 72 queens from 24 apiaries in 2008. Queens were analysed for the presence of four viruses: acute bee paralysis virus (ABPV), black queen cell virus (BQCV), sacbrood virus (SBV) and deformed wing virus (DWV) by using reverse transcription polymerase chain reaction (RT-PCR). In 2006, 12%, 9% and 1% prevalence was found for ABPV, DWV and SBV, respectively; BQCV was not detected. Two years later, DWV, BQCV, SBV and ABPV were detected in 58%, 24%, 11% and 10% bee queens, respectively. In 2006, fourteen out of twenty-seven apaiaries were virus free, whereas in 2008 only three out of twenty-four apiaries were virus free. This is the first evidence of virus infection occurring in newly mated queens from mating nuclei in rearing apiaries. The possible impacts of queen rearing technology and epidemiological influences on virus infection are discussed in this study.

Full textAbstract:
AbstractMass storage of honey bee (Apis mellifera L.) queens over the winter was investigated in colony banks, with each queen held in her own cage within a colony. The major treatments included: (I) a single queen wintered in a small nucleus colony (control); and colony banks with 24 or 48 queens, each held individually in (II) screen cages that prevented workers from entering the cage, but allowed access for queen tending, (III) queen-excluder cages (queen-excluder material has openings of about 55 mm that prevent the larger queen but not the smaller workers from passing through the material), or (IV) screen cages until January and subsequent transfer to mini-nuclei until late March. Queens held in excluder cages showed poor survival in all 3 years of testing, and this system was not viable for commercial use; survival for any 1 year, or any excluder treatment, was never greater than 25%. In contrast, a 2-year average of 60% queen survival was found for queens that were stored in individual screened wooden cages within queenless colony banks. We found no differences in survival of banked queens that were moved between colonies monthly and those that remained in the same colony for 6 months. The success of these systems required the (a) preparation of colony banks that contained large numbers of adult workers produced by maintaining colonies with two queens during the previous summer, (b) removal of laying queen(s) during the storage period, (c) feeding of colonies well, and (d) insulation of colonies in groups of four, to preserve heat and reduce worker clustering in the winter. Surviving queens from winter storage systems were virtually identical in quality and colony performance to control queens the subsequent season. The annual profit for a commercial beekeeper who does his/her own labour for storage and hires workers for queen production was calculated as $16,625 when 4800 queens are stored over the winter, and sold for $10 each in the spring. Thus, mass queen storage using our successful systems is both biologically and economically viable.

Queen-worker caste dimorphism is a typical trait for honeybees (Apis mellifera). We previously showed a maternal effect on caste differentiation and queen development, where queens emerged from queen-cell eggs (QE) had higher quality than queens developed from worker cell eggs (WE). In this study, newly-emerged queens were reared from QE, WE, and 2-day worker larvae (2L). The thorax size and DNA methylation levels of queens were measured. We found that queens emerging from QE had significantly larger thorax length and width than WE and 2L. Epigenetic analysis showed that QE/2L comparison had the most different methylated genes (DMGs, 612) followed by WE/2L (473), and QE/WE (371). Interestingly, a great number of DMGs (42) were in genes belonging to mTOR, MAPK, Wnt, Notch, Hedgehog, FoxO, and Hippo signaling pathways that are involved in regulating caste differentiation, reproduction and longevity. This study proved that honeybee maternal effect causes epigenetic alteration regulating caste differentiation and queen development.

Extreme temperature exposure can reduce stored sperm viability within queen honey bees; however, little is known about how thermal stress may directly impact queen performance or other maternal quality metrics. Here, in a blind field trial, we recorded laying pattern, queen mass, and average callow worker mass before and after exposing queens to a cold temperature (4°C, 2 h), hot temperature (42°C, 2 h), and hive temperature (33°C, control). We measured sperm viability at experiment termination, and investigated potential vertical effects of maternal temperature stress on embryos using proteomics. We found that cold stress, but not heat stress, reduced stored sperm viability; however, we found no significant effect of temperature stress on any other recorded metrics (queen mass, average callow worker mass, laying patterns, the egg proteome, and queen spermathecal fluid proteome). Previously determined candidate heat and cold stress biomarkers were not differentially expressed in stressed queens, indicating that these markers only have short-term post-stress diagnostic utility. Combined with variable sperm viability responses to temperature stress reported in different studies, these data also suggest that there is substantial variation in temperature tolerance, with respect to impacts on fertility, amongst queens. Future research should aim to quantify the variation and heritability of temperature tolerance, particularly heat, in different populations of queens in an effort to promote queen resilience.

Full textAbstract:
Honey bees play an important role in modern agriculture as farm animals and crop pollinators and represent an animal model in scientific research. Since few decades, managed honey bees are facing large scale losses worldwide due to the interaction of several biotic and abiotic factors such as the spread of pathogens and parasites, the habitat loss, the use of pesticides, and the occurrence of climate changes. For years, beekeepers have controlled deadly pathogens such as Varroa destructor with acaricides (pyrethroid), but widespread chemical resistance is manifesting. Alternative management strategies could be developed to characterize and select bees with heritable traits allowing them to resist mites and diseases. Hygienic behaviour (HB) is a heritable phenotype that confers colony level resistance against brood disease, with a potential effect on the damaging parasitic mite V. destructor. Unfortunately, breeding such bees is complicated as the assays involved to characterize such phenotype are time-consuming and expensive if performed on a consistent number of colonies. Additionally, the mechanisms behind social immunity are not yet fully understood. These issues have motivated the scientific community to develop research tools that can offer insight into the causes of declining bee health as well as identify biomarkers to guide breeding programs.
The studies presented in this thesis are the results of the collaboration between the Animal Genetic Group of the University of Milan and an Italian beekeeping company, which made available its animals for the majority of the studies presented in this work. The first two chapters of this thesis focus on three important aspects regarding hygienic behaviour: in-field phenotypic implementation of a method to measure HB on large testing populations, its genetic parameters estimation and developing molecular tools for the identification of potential HB genetic markers from breeding queens.
Queens are the only fertile females of the colony, responsible for laying eggs and maintaining the cohesion of the colony. The quality of the queen may have an important effect on a colony’s development, productivity and survival and queen failure or loss is considered a cause of the decline of colonies worldwide. The queen quality, resulting from her genetic background, developmental condition, mating success and environment, can be assessed by some morphological measures. We investigated the genetic parameters of some traits that describe the quality of bee queens in the third chapter.
Beside queen morphology, in the fourth chapter, we investigated also the morphology of the worker bees with Computed Tomography (CT). In this study, a non-invasive CT technique and image analysis approach coupled with brood manual inspection was used to clarify the relationship between honey bee pupa length and its varroa mite infestation status, developmental status and spatial position within the brood comb. The results of this chapter suggest that the CT-scan may represent a suitable non-invasive tool to investigate the morphology and developing status of honey bee brood.
Finally, since honey yield is one of the major breeding goal for a beekeeping company, we investigated the genetic parameters for honey yield in a small testing population of honey bees in Northern Italy both considering the total honey yield and the single harvests of a colony within a year on data collected over a period of three years.

To evaluate interaction of water alkalinity and stocking density on body ionic levels, survival, growth and behavior of silver catfish, Rhamdia quelen, juveniles, a short-term experiment (96 h) analyzed the effect of three alkalinity levels (30, 80 and 130 mg/L CaCO3) and four stocking densities (4, 8, 16, and 24 g/L). In addition, a growth experiment of 30 days verified the effect of three stocking densities (4, 8, 16 g/L) and the same alkalinity levels. Survival and body ionic levels were not significantly affected in the short-term experiment, but after 30 days survival was significantly reduced in the group maintained at the stocking density of 16 g/L and 30 mg/L CaCO3. However, this treatment provided higher weight and specific growth rate compared to the treatment with the highest alkalinity and the same stocking density. The time of capture of the food, in both experiments, was faster in the treatments of high stocking density. In the short-term experiment fish remained mainly in the bottom, and the reduction of stocking density increased swimming speed. The color of the animals was significantly clearer in the lowest densities of the growth experiment. Agonistic side behaviors prevailed in the lowest alkalinities of the stocking density of 8 g/L, and cannibalism occurred only in the stocking density of 8 g/L and alkalinity of 130 mg/L CaCO3 of the growth experiment. The stocking density of 16 g/L and alkalinity of 80 mg/L CaCO3 seems to be the most appropriate for silver catfish juveniles growth in these experimental conditions.Com o objetivo de avaliar a interação da alcalinidade da água com diferentes densidades de estocagem sobre os níveis iônicos corporais, sobrevivência, crescimento e comportamento de juvenis de jundiá, Rhamdia quelen, delineou-se um experimento de curta duração (96 h) com três níveis de alcalinidade (30, 80 e 130 mg/L CaCO3) e quatro densidades de estocagem (4, 8, 16 e 24 g/L). Além disso, em um experimento de crescimento (30 dias) testou-se três densidades de estocagem (4, 8, 16 g/L) e as mesmas alcalinidades. A sobrevivência e os níveis iônicos corporais não foram afetados no experimento de curta duração, mas após 30 dias a sobrevivência foi reduzida no tratamento de maior densidade e menor alcalinidade. Este mesmo tratamento foi o que obteve melhores resultados de peso e taxa de crescimento específico em relação à maior alcalinidade da mesma densidade. O tempo de captura do alimento, em ambos experimentos, foi mais curto nos tratamentos de maior densidade. No experimento de curta duração os peixes se concentravam mais no fundo à medida que se diminuía a densidade de estocagem e com o aumento desta aumentou a velocidade de natação. A coloração dos animais foi significativamente mais clara nas menores densidades do experimento de crescimento. Confrontos laterais predominaram nas menores alcalinidades da densidade de 8 g/L, canibalismos ocorreram apenas na densidade de 8 g/L e alcalinidade de 130 mg/L CaCO3 do experimento de crescimento. A utilização da densidade de estocagem de 16 g/L e alcalinidade de 80 mg/L CaCO3 é a mais adequada para o cultivo de juvenis de jundiá nestas condições experimentais.

Previous issue date: 2014-12-09The consequences of water contamination are serious and should be evaluated by testing with biochemical and biological parameters, using the biomarkers. It is known that the main sources of water contamination are urban untreated sewage that are released into rivers and lakes, landfills affecting groundwater, pesticides that flow with the rain being swept into the rivers and lakes and industries who use the rivers as carriers of their toxic waste. These wastes and substances released into the body of water has been the subject of many studies, especially those that aim to assess the consequences of genotoxic substances on the DNA of fish. Still related to water quality, and the use of biomarkers, was sought to constantly gene responses to environmental stimuli. Thus, the present study aimed to evaluate the genotoxic effects in fish species R. quelen (popularly known as Jundiá) submitted to the waters of the river Caveiras, at a specific point. For this, we used techniques: the micronucleus test and the comet assay as biomarkers of effect of water contaminants in fish studied. We compared the incidence of micronuclei and the appearance of DNA damage in blood cells of R. quelen exposed to the waters of the river Caveiras at the point analyzed, with blood cells of fish of the same species, a control group, kept in waters originating from aquaculture laboratory of CAV / UDESC. The animals in both the control for the test, were kept at temperatures ranging from 22 to 28 degrees Celsius, with mechanical ventilation, and even diet management. We analyzed damage index by the comet assay in four different times (0, 7, 21 and 28 days). No significant differences were seen when the Test and Control groups compared, between times 0 and 7 days. The observation time 21 compared to the other times, we could notice a significant increase (p <0.001) in the rate of DNA strand breaks in fish in the test group compared to the control group. In 28 day time, when the fish of the test group returned the same conditions in the control group, we observed a significant decrease in DNA damage when purchased from the ratios obtained in time for 21 days. The results of the micronucleus test in R. quelen exposed to the waters of the river Caveiras showed no significant differences for any of the times sampled. Therefore, it is concluded that the water river Caveiras is the main cause of genotoxic damage observed in fish in the analyzed point and the Comet assay, relative to MN, was more sensitive in detecting DNA damage
As consequências da contaminação dos recursos hídricos são graves e devem ser avaliadas através de análises com parâmetros bioquímicos e biológicos, utilizando-se de bioindicadores. Sabe-se, que as principais fontes de contaminação dos recursos hídricos são esgotos urbanos sem tratamento que são lançados em rios e lagos, aterros sanitários que afetam os lençóis freáticos, defensivos agrícolas que escoam com a chuva sendo arrastados para os rios e lagos e indústrias que utilizam os rios como carreadores de seus resíduos tóxicos. Estes dejetos e substâncias liberadas no corpo d´água tem sido alvo de muitos estudos principalmente daqueles que visam avaliar as consequências de substâncias genotóxicas sobre o DNA de peixes. Ainda, relacionado à qualidade das águas, e com a utilização de bioindicadores, buscam-se, constantemente, respostas dos genes aos estímulos ambientais. Desta forma o presente estudo teve como objetivo principal, avaliar os efeitos genotóxicos em peixes da espécie Rhamdia quelen (popularmente conhecidos como Jundiás) submetidos às águas do Rio Caveiras, em um ponto específico. Para tanto, utilizou-se as técnicas: Teste do Micronúcleo e o Ensaio Cometa, como biomarcadores de efeito de contaminantes da água nos peixes estudados. Comparou-se a incidência de micronúcleos e o aparecimento de danos ao DNA em células sanguíneas de R. quelen expostas às águas do Rio Caveiras no ponto analisado, com células sanguíneas de peixes da mesma espécie, de um grupo controle, mantido em águas oriundas do laboratório de piscicultura do CAV/UDESC. Os animais, tanto do controle quanto do teste, foram mantidos em temperaturas que variaram de 22 a 28 graus Celsius, com aeração mecânica, mesmo manejo e dieta alimentar. Analisou-se índice de danos, através do ensaio cometa, em quatro tempos diferentes (0, 7, 21 e 28 dias). Não foram evidenciados diferenças significativas, quando comparados os grupos Teste e Controle, entre os tempos 0 e 7 dias. Na observação do tempo 21, em comparação com os outros tempos, pôde-se perceber um aumento significativo (p < 0,001) do índice de quebras no DNA nos peixes do grupo teste quando comparados aos do grupo controle. No tempo 28 dias, quando os peixes do grupo teste retornaram as mesmas condições do grupo controle, observou-se uma diminuição significativa dos danos no DNA quando comprados aos índices obtidos no tempo de 21 dias. Os resultados do Teste do Micronúcleo em R. quelen expostos às águas do Rio Caveiras mostraram que não houve diferenças significativas para nenhum dos tempos amostrados. Conclui-se, portanto, que a água do Rio Caveiras é a principal causadora dos danos genotóxicos observados nos peixes no ponto analisado e que o Ensaio Cometa, em relação ao MN, foi mais sensível na detecção de danos no DNA

Full textAbstract:
La culture de l'ananas s'est fortement développée à la Réunion et représente la première production fruitière de l'île en termes de valeur et de tonnage exporté. L'hétérogénéité des conditions climatiques de l'île ainsi que la diversité des pratiques culturales, notamment en ce qui concerne la fertilisation azotée et l'irrigation, mène à une forte variabilité des rendements, de la qualité gustative des fruits et d'utilisation des ressources naturelles du milieu. Le développement de systèmes de culture plus durables impose de repenser et d'optimiser l'assemblage des pratiques culturales, en prenant en compte les spécificités des différentes zones de production. Un modèle ad-hoc, SIMPIÑA a été développé afin de décrire la croissance et le développement de la plante et la qualité gustative des fruits (teneur en sucres et en acides) en fonction du climat et des pratiques culturales (poids de rejets plantés, densité, date d'induction florale, fertilisation et irrigation). Ce modèle présente la particularité d'intégrer des modules mécanistes (croissance de la plante, teneur en sucre des fruits, bilans hydriques et azotés) et des modules statistiques pour la prévision de l'acidité des fruits à la récolte et la partie économique. Les pratiques culturales sont prises en compte au travers de règles de décision qu'il est ainsi possible d'évaluer. Une typologie des pratiques culturales a été élaborée sur 40 exploitations de l'île, en amont, afin de réduire le champ des possibles et permettre de proposer des systèmes de culture innovants, en optimisant les performances des systèmes tout en prenant en compte les principales contraintes des exploitations. SIMPIÑA a été utilisé pour identifier des combinaisons de pratiques culturales des systèmes qu'il conviendra de tester « au champ ». Cette approche intégrative a permis des avancées significatives au niveau de la modélisation de la culture de l'ananas et de la définition de systèmes de culture innovantsPineapple production is increasing on Réunion Island and represents the first fruit production, in terms of value and yield exported. The heterogeneity of climatic conditions on the island and the diversity of cultural practices, particularly with regard to nitrogen fertilization and irrigation, lead to a high variability in yield, gustatory quality of fruit and use of natural resources. The development of more sustainable cropping systems requires rethinking and optimizing the combination of agricultural practices, by taking into account the specificities of the different production areas. An ad-hoc model, SIMPIÑA was developed to describe the growth and development of pineapple plant and fruit quality (sugar and acid content) depending on climate and cultural practices (sucker weight at planting, planting density, date of flowering induction, fertilization and irrigation). This model has the particularity to integrate process-based model modules (plant growth, sugar content, water and nitrogen balance) and statistical modules (for predicting the acidity of fruit at harvest and the economic part). Cultural practices are taken into account through decision rules that may thus be assessed with the model. A typology of cultural practices was carried out based on interviews of 40 farmers all over Réunion Island and led to three farm's types with specific climatic and organizational constraints. SIMPIÑA was used to explore a wide range of combination of cultural practices, taking into account the constraints of each farm-type. We identified trends of cultural practices combinations which optimize the performances of the systems and that should be tested in the field. This integrative approach has led to significant advances in modeling pineapple production and in defining innovative cropping systems

Full textAbstract:
The effects of water pH, hardness and temperature on anesthesia induction and
recovery in silver catfish exposed to different concentrations of eugenol (20, 30 and 40 mg/L)
were investigated. Moreover, the effects of anesthesia and temperature on blood gases
tensions (PvO2 and PvCO2) and pH were also analyzed in juveniles I (3.5 ± 0.7 g; 7.7 ± 0.8
cm) and juveniles II (152.2 ± 3.4 g; 26.6 ± 3.3 cm) of silver catfish. Water quality and fish
size affect efficacy of eugenol in silver catfish, mainly in the lower concentrations tested.
Sedation of this species can be induced even with 20 mg/L, but for anesthesia a concentration
of at least 40 mg/L eugenol must be used to reduce the influence of the studied fish size and
water quality. Blood gases tensions and pH were affected by eugenol anesthesia only in fish
acclimated to 30 oC.Investigou-se os efeitos do pH, dureza e temperatura da água sobre a indução à anestesia e recuperação em jundiás expostos a diferentes concentrações de eugenol (20, 30 e 40 mg/L). Além disso, os efeitos da anestesia e temperatura sobre as pressões parciais dos gases sanguíneos (PvO2 e PvCO2) e pH foram também analisados em juvenis I (3,5 ± 0,7 g; 7,7 ± 0,8 cm) e juvenis II (152,2 ± 3,4 g; 26,6 ± 3,3 cm) de jundiá. A qualidade da água e o tamanho do peixe afetam a eficácia do eugenol em jundiá, principalmente nas menores concentrações testadas. A sedação desta espécie pode ser induzida com 20 mg/L, mas para a anestesia uma concentração de cerca de 40 mg/L de eugenol deve ser utilizada para reduzir a influência do tamanho do peixe e da qualidade da água. As pressões parciais dos gases sanguíneos e o pH foram afetados pelo eugenol durante a anestesia em peixes aclimatados a 30oC.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThis study was conducted to evaluate growth, lipid profile, metabolism and fillet aceitability of jundiá. For this purpose four experiments were conducted in a completely randomly design, where jundiás of the same genetic origin were reared in water re-use system. In the first, it was evaluated four densities (4.2, 6.4, 8.6 and 10.8 kg/m3) in jundiás of both sexes. It was used a total of 420 fish (IW=182.95 ± 2.96 g), that were fed for 120 days until the apparent satiation. It was verified a weight decrease of fish with the increase of the SD used, with elevation of the plasmatic cortisol. In the second experiment, it was tested the sex and dietary protein level influence. In factorial arrangement 2 X 3 (two sexes and three protein levels: 24, 27 and 30% of CP), 270 fish (IW=207.02 ± 26.73 g) were fed controlled during 100 days. The females showed higher growth, with lower protein requirement (24% CP) than that of males (30% CP). These showed higher fillet yield. The increase of the diet protein provided improvement in the fillet lipid profile. Two additional experiments were conducted separately to evaluate the use of soybean oil in the diet (0, 2, 4, 6, 8 e 10% of inclusion, feeding until the satiation). The males (234, IW=193.32 ± 18.78 g 120 days experiment) fed with 8% soybean oil showed better performance. The females (144, IW=237.75 ± 22.35 g 80 days experiment) fed with 10% soybean oil had obtained higher final weight. The feed apparent consumption was higher in males. The higher soybean oil inclusion in the diets decreased the amount of saturated fatty acids and increased polynsaturated fatty acids in jundiá fillets. No differences were detected by the taste panel in the flavor, texture and appearance of the fillets regardeless of fish sex.
Este trabalho foi conduzido para avaliar o crescimento, perfil lipídico, metabolismo e aceitabilidade dos filés de jundiás. Para isso foram conduzidos quatro experimentos delineados inteiramente ao acaso, onde jundiás de mesma origem genética foram criados em sistemas com recirculação de água. No primeiro, foram avaliados quatro densidades de estocagem (4,2, 6,4, 8,6 e 10,8 kg/m3) em jundiás de ambos os sexos. Utilizou-se um total de 420 peixes (Pi=182,95 ± 2,96 g), que foram alimentados durante 120 dias até a saciedade aparente. Verificou-se diminuição no peso dos peixes com o aumento da densidade utilizada, com elevação do cortisol plasmático. No segundo experimento, testou-se a influência do sexo e do nível de proteína dietário. Em arranjo fatorial 2 X 3 (dois sexos e três níveis protéicos: 24, 27 e 30% de PB), 270 peixes (Pi=207,02 ± 26,73 g) foram alimentados controladamente durante 100 dias. As fêmeas apresentaram crescimento superior, com exigência protéica menor (24% PB) que os machos (30% PB), os quais apresentaram maior rendimento de filé. O aumento da proteína da dieta proporcionou melhora no perfil lipídico dos filés. Foram conduzidos mais dois experimentos separadamente avaliando a utilização do óleo de soja na dieta (0, 2, 4, 6, 8 e 10% de inclusão, alimentação até a saciedade). Os machos (234, Pi=193,32 ± 18,78 g 120 dias de experimento) alimentados com 8% de óleo apresentaram melhor desempenho. As fêmeas (144, Pi=237,75 ± 22,35 g 80 dias de experimento) alimentadas com 10% de óleo obtiveram maior peso final. O consumo aparente de alimento foi maior nos machos. A maior inclusão de óleo de soja nas dietas proporcionou diminuição na quantidade de ácidos graxos saturados e aumento de poliinsaturados (PUFAS) nos filés dos jundiás. Não foram detectadas diferenças pelo painel de provadores no sabor, textura e aparência dos filés de jundiás de ambos os sexos.

The objective of this study was to avaluate the toxicity to Daphnia magna cultivated on a large scale and post-larvae of jundia (Rhamdia quelen) to Glyphosate herbicide and the reference substances. Were used daphnia with age between 2 and 26 hours of life, from large scale cultured arrays. There were performed six sensitivity assays that were composed of seven treatments and three replica, at concentrations of 0; 0.1; 0.3; 0.5; 0.7; 0.9 and 1.2 mg.L-1 of potassium dichromate, with 24 hours duration. The acute toxicity assays, with copper sulfate at concentrations of 0; 0.01; 0.025; 0.05; 0.075 and 0.10 mg.L-1, and to the glyphosate concentrations of 0; 11; 21; 31; 41 and 51 µg.L-1, with three and two replica respectively, and 48 hours duration. However the post-larvae of jundia were exposed to concentrations of 0; 0.5; 1.0; 1.5; 2.0 and 2.5 mg.L-1 of glyphosate, per 96 hours. Each replica was composed of a bottle with 10 individuals. The chronic toxicity test, the daphnia were exposed to concentrations of 0, 2, 4, 6, 8 and 10 µg.L-1 of glyphosate, with 10 replica, being a daphnia per replica, evaluating the survival and fecundity in 21 days. For acute toxicity assays, was calculated mortality using the Median Effective Concentration (EC50) in each test. The mean EC50 for D. magna with potassium dichromate was 0.57 mg.L-1. The value of acute toxicity for copper sulphate was reached at a concentration of 0.034 mg.L-1. And for the glyphosate the EC50 of 32 µg.L-1 is toxic for the species. The chronic assay showed high rate of mortality, possibly the result of unfavourable conditions for the large scale cultivation of arrays, hurt his endurance. For the R. quelen the EC50 was achieved at 0.9 mg. L-1. The results showed that organisms of the species D. magna cultivated on a large scale can be used in acute toxicity tests, but not in chronic toxicity testing, for the assessment of water quality.
O objetivo deste trabalho foi avaliar a toxicidade de Daphnia magna cultivada em larga escala e pós-larvas do jundiá (Rhamdia quelen) ao herbicida Glifosato e a substâncias de referência. Foram utilizadas dáfnias com idade de 2 a 26 horas de vida, provenientes de matrizes cultivadas em larga escala. Foram realizados seis ensaios de sensibilidade que foram compostos por sete tratamentos e três réplicas, nas concentrações de 0; 0,1; 0,3; 0,5; 0,7; 0,9 e 1,2 mg.L-1 de dicromato de potássio, com duração de 24 horas. E os testes de toxicidade aguda, com sulfato de cobre nas concentrações de 0; 0,01; 0,025; 0,05; 0,075 e 0,10 mg.L-1, e para o glifosato as concentrações de 0; 11; 21; 31; 41 e 51 µg.L-1, com três e duas réplicas respectivamente, e duração de 48 horas. Já as pós-larvas de jundiá foram expostas às concentrações de 0; 0,5; 1,0; 1,5; 2,0 e 2,5 mg.L-1 de glifosato, por 96 horas. Cada réplica era composta de um frasco com 10 indivíduos. No teste de toxicidade crônica, as dáfnias foram expostas as concentrações de 0, 2, 4, 6, 8 e 10 µg.L-1 de glifosato, com 10 réplicas, sendo uma dáfnia por réplica, avaliando a sobrevivência e fecundidade em 21 dias. Para os experimentos de toxicidade aguda foi calculada mortalidade através da Concentração Efetiva Mediana (CE50) em cada teste. A média da CE50 para a D. magna com dicromato de potássio foi de 0,57 mg.L-1. O valor de toxicidade aguda para o sulfato de cobre foi alcançado na concentração de 0,034 mg.L-1. Já para o glifosato a CE50 de 32 µg.L-1 é toxica para a espécie. No teste crônico, a alta taxa de mortalidade possivelmente é resultado das condições desfavoráveis no cultivo das matrizes em larga escala, o que prejudicou sua resistência. Para o R. quelen a CE50 alcançada foi em 0,9 mg.L-1. Os resultados demostraram que organismos da espécie D. magna cultivadas em larga escala podem ser utilizados em testes de toxicidade aguda, mas não em testes de toxicidade crônica, para a avaliação da qualidade da água.

Full textAbstract:
Total Quality Management (TQM) has become the focus of all organisations that strive for excellence in service delivery. The healthcare sector is not an exception though it is exclusively different from other organisations because of the nature of service they provide, and the kind of risk involved in service provision. The aim of this study was to assess employees’ perceptions about TQM at Queen Elizabeth II hospital, and their expectations regarding TQM implementation in the new Private Public Partnership (PPP) National Referral hospital. It also sought to measure the gap that exists between employees’ perceptions and expectations. It focused on three fundamental principles of Total Quality (TQ), namely ‘focus on customers and stakeholders’, ‘participation by everyone and teamwork’, as well as ‘process focus and continuous improvement’.
This, quantitative research study, utilised a cross-sectional approach. The self-administered questionnaires were employed to obtain data. A stratified sample of 240 employees was drawn from Q.E.II hospital employees, which represented a population size of approximately 685 employees. Out of the sample size of 240, only 157 questionnaires were completed and returned. The respondents comprised of 38.2% males and 61.8% females. The highest percentage of the respondents (53.5%) was in the clinical category; 33.8% in Administration; 8.3% in ‘other’ health professionals such as pharmacy, laboratory, and radiology. The lowest percentages of 3.8% and 0.6% were in Accountancy and Human Resources categories respectively.
The findings of this study revealed that employees have relatively low perceptions about TQM at Q.E.II hospital, while their expectations regarding TQM in the new PPP National referral hospital are extremely high. Process focus and continuous improvement attained a larger overall gap between perceptions and expectations. Although an analysis revealed that focus is needed in all areas that constitute total quality, but evidence suggests that process focus and continuous improvement need special attention. Thus, it is recommended that management creates a quality culture through strong leadership, putting the needs of both employees and patients in the fore-front, ensuring that employees understand hospital processes, and mostly, continuously improving the hospital processes.Thesis (MBA)-University of KwaZulu-Natal, Westville, 2010.

ABSTRACT This study consists of three major sections. The first section studied about the addition of different yeasts and different storage period on the quality and flavors of Black Queen wines. Result shown that the microbiological reaction and flavors are time dependent. The color index also increased proportionally to time effect. The second section studied about the addition of L. oenoson the quality and flavor of Black Queen wines ,the content of lactate keep constant not matter if the L. oenos was added or not. The third section is subjected to the investigation of the composition and flavor component of several Black Queen wines produced locally in Taiwan.The best Black Queen wine wasfound to be the one which contain the sugar amount between 20.1 and 26。Brix, the alcohol amount between 12.57% and 13.14%. Also by using the method of solution extracting and GC-MS analysis, the predominant flavor ingredients found in several local Black Queen wines were isoamyl alcohol,isobutyl alcohol,ethyl acetate and ethyl lactate.

Full textAbstract:
Before the 4th instar larval phase, worker larvae exhibit totipotency to develop into either female caste. In subsequent larval stages, differential expression of various genetic elements occurs under the prominent induction of royal jelly, developmental hormones, and volatile queen emission. In the honey bee female caste, anatomical reproductive disproportionality establishes due to this diversification of genomic expression. Exponential fertility and pheromonal profiling of the queen regulate colonial strength, colonial productivity, submissive behaviour, and the development of workers. Different factors prevailing within the hive or outside of the colony premises influence the queen's quality. For example, the queen's fecundity is negatively proportional to the age of the worker larva before entering the queen differentiation pathway. Further, numerous additional factors like genomic content, physiology, quality and quantity of royal jelly, colonial food storage, social environment, queen pheromones, etc. influence queen reproductive potential. Further, queens have differential immune protective characteristics for different pathogens and parasites. This chapter highlights influencing factors for non-synchronous ovarian development and variant immune-protective measures in female honey bees. The subsequent chapters elucidate the details of workers' ovarian programmed cell death under the regulation of multiple factors.

This chapter considers two projects headed by Ava DuVernay: the Netflix documentary 13th and OWN’s drama series Queen Sugar. Although they approach the topic of mass incarceration through drastically different genres, each seek to incorporate aspects of Black studies scholarship into their respective brands of advocacy documentary and serial TV melodrama. Together they historicize mass incarceration’s roots in slavery in ways which prove conducive to the exploration of the changing contours of Black representation across media forms. However, these treatments nevertheless remain largely entangled with problematic traditions of American melodramatic storytelling.

Your Majesty […] (as the Mirror of her sexe & quality), the most incomparable in generosity and affability by right termed the Queene of ♥.1 So wrote diplomat, spy, and art broker Sir Balthazar Gerbier in a letter of 1639. The recipient was Elizabeth Stuart (1596–1662), daughter of James VI/I, sister to Charles I, and aunt to Charles II. By the time of her death at the age of 65, she had lived through the reigns of her father and brother, the decade of the Commonwealth and Protectorate, and seen her nephew restored to the throne of the three kingdoms of England, Scotland, and Ireland. She was at the centre of the political and military struggle that was the Thirty Years War (1618–48), acting as powerbroker between the great families of Europe, not always successfully, and yet forged a dynasty that led directly to the Hanoverian succession of 1714: King George I was her grandson....

Full textAbstract:
Members of the Bloomsbury Group wrote biographical texts influenced by the camp style of Lytton Strachey in Eminent Victorians and Queen Victoria. The most noticeable effect of this style is the subversion of Victorian biographical conventions. Stracheyesque qualities can be found in Virginia Woolf’s Orlando and Flush, John Maynard Keynes’ The Economic Consequences of the Peace, Clive Bell’s Old Friends, and E.M. Forster’s early nonfiction sketches and his biographies of Goldsworthy Lowes Dickinson and Marianne Thornton. Especially in their biographical writings these figures felt free to emphasize exaggeration, even silliness, in contrast to the psychological realism prevalent in their own and others’ fictional literary experiments. The Stracheyesque note in Bloomsbury biography provides a common quality and arguably queers readers’ expectations of modernist literary practices. As with the pervasive irregularity of their sexual practices, such textual play might be understood as liberatory and subversive.

Full textAbstract:
The 1970s saw a mass exodus of younger, artistically ambitious directors from moviemaking for the big screen into TV. Among the beneficiaries of the new medium was Igor Maslennikov, who had struggled to establish himself as more than “promising.” Maslennikov’s TV adaptations of Sherlock Holmes rapidly made him one of the most famous filmmakers in the USSR. The main subject of this chapter, however, is an adaptation for “quality TV” of a different kind, The Queen of Spades, by Russia’s most famous writer, Alexander Pushkin. Where Maslennikov’s Conan Doyle adaptations were studiedly casual (The Hound of the Baskervilles is an exercise in playful eccentricity rather than a plunge into Victorian Gothic), his reworking of Pushkin went precisely in the other direction. This “hyperauthentic” interpretation of the Russian author sought to retain “every last comma” in the original, right down to scene-setting commentaries presented by an on-screen narrator. As this chapter argues, had it not been for the exceptionally vexed history of attempts to film The Queen of Spades (Maslennikov was the fourth director selected to make the movie), his “hyperauthentic” approach might have proved more controversial. Whichever way, the adaptation more closely resembles late modernist films of the era such as Eric Rohmer’s The Marquise of O than the conventional literary adaptations of the later Soviet era, which came from a tradition where reconstructing the source text was the accepted norm.

The article is devoted to the processes of reproduction of infertile and fertile Queen bees. Some ethological features of Central Russian bees, as well as the difficult climatic conditions in which they are bred, lead to a decrease in the profitability of the process of obtaining Queens of this breed. The search and implementation of new methods of reproduction of Queens in the practice of beekeeping will allow you to get a greater number of high-quality Central Russian Queens.

Full textAbstract:
The MT30 is the latest and most powerful gas turbine to enter the marine market. Recently entering US Navy service in USS Freedom, the first-of-class Littoral Combat Ship (LCS), MT30 has now been selected to be the prime power plant for two further classes of front-line warships; The Queen Elizabeth Class Aircraft Carriers for the Royal Navy, and the US Navy DDG-1000 Destroyers. This paper tracks the development of the MT30 from its well-established Rolls-Royce Aero Trent parent, discussing the changes necessary to adapt and harden the gas turbine for the marine application. The MT30 development program is described, including the rigorous testing undertaken to qualify the engine to American Bureau of Shipping (ABS) rules. Existing and future applications for the MT30 are described. Systems for achieving efficient hybrid propulsion utilising electric motors for cruise and the MT30 for boost are presented. The latest all-electric marine propulsion architectures as used on DDG-1000 and the Queen Elizabeth Class Carriers is discussed -in particular, the issue of maintaining the quality of power supply through transient load demands. The paper concludes with an insight into the latest MT30 package, which sees the system reaching class-beating power densities whilst ensuring maintainability through innovative design features.

Full textAbstract:
The proposed paper analyses the system of small buildings that compose the Hameau de la Reine in the Petit Trianon gardens in the park of the royal palace of Versailles. The complex of architectural artefacts, built at the end of the 18th century, emulates the features of vernacular architecture typical of the villages of Normandy. The main interest lies in the analysis of the masonry which reproduces the signs of wear caused by the salty coastal climate of northern France using the trompe-l'oeil technique. The study of the architectural elements found in this part of the park of Versailles, using the tools of the restoration discipline, makes possible the highlighting of the specific qualities that confer recognizability on both the vernacular architecture and its reproductions. The design of this section of Queen Marie-Antoinette's Domaine identifies an ideological root in eighteenth-century Enlightenment thinking from which came the physiocratic theories expressed by Quesnay and the Marquis de Mirabeau. The contribution intends to underline, through the analysis of the method of imitation of vernacular architecture, the importance that this architectural typology assumes in the process of rediscovery and fruition of the territory. The analysis of the Hameau complex testifies how vernacular architecture, not yet codified according to this terminology, was already identified at the end of the 18th century as an example of high quality value that found its effective collocation within the boundaries of the royal park of Versailles. The characteristics of this architecture allow it to find an effective place even inside the perimeter of the royal park of Versailles. It is possible to identify the prodromes of the modern architectural sensibility that recognizes and codifies the values of vernacular architecture within the site studied by this paper proposal.

Full textAbstract:
Quyen Le, Deputy Director at ABC Textile and Dyeing Joint Venture Company (JVC), returned from a meeting with an Enterprise Resource Planning (ERP) service provider. Quyen was wondering which options of ERP implementation would be best suited to gain staff support and pre-pared the company for long term development. ABC had undergone considerable growth in recent years. Having become one of leading manufacturers of denim fabric in Vietnam market, the company was now facing some organizational challenges. To cope with pressing competition in local and overseas markets, ABC had needed to acquire internationally recognized certification for its quality control system and standardized manufacturing process. The company implemented a quality management process in order to achieve its goal of ISO9000:2008 certification. There was substantial additional paperwork to be handled with the new process. ABC currently used an outdated decentralized computing system in managing its denim manufacturing process. It was time-consuming and difficult to obtain timely and accurate production information—including material planning, production costing, machinery inventory, production reports—and difficult to share information among departments. Furthermore, over a hundred different reports for various stages of the denim manufacturing process were generated and handled by several departments. Lacking the technical knowledge to deal with complex technological context, Quyen considered outsourcing the implementation of an ERP system to ease the documentation tasks required by the ISO 9000:2008, and to manage more effectively the denim manufacturing and to streamline the reporting system. Facing concerns and criticisms from staff during the implementation of the ISO 9000:2008 quality management process due to its complex, time-consuming documentation requirement and added workload with no immediate benefits, Quyen was facing a tough decision whether to move forward with implementing an ERP system that promised another tough challenge to get the sup-port from staff and required necessary organizational changes to create business value from the information technology (IT) investment. ABC Textile and Dyeing JVC (ABC) was part of a textile industry that represented an important component of the global and local economies.

In RECH6 - 6th International Meeting on Retouching of Cultural Heritage. València: Editorial Universitat Politècnica de València, 2021. http://dx.doi.org/10.4995/rech6.2021.13544.
Full textAbstract:
A major conservation and research project on The Visit of the Queen of Sheba to King Solomon by Lavinia Fontana was completed at the National Gallery of Ireland in Dublin in 2021. The painting, a large-scale oil on canvas (256 x 325 cm), was one of a number of pictures restored in the late 1960s by a team of conservators from the Istituto Centrale del Restauro in Rome, who came to Dublin during the establishment of the first conservation studio at the Gallery. The visiting restorers brought novel ideas and materials with them from the Istituto that would shape the Irish approach to conservation for decades to come. The prevailing ethos at the time in Italy was based on a minimal intervention approach with the use of novel, synthetic materials that had not yet been introduced to the collection of the National Gallery of Ireland. The painting, after treatment by the Istituto team, recorded material evidence of a particular moment in the development of conservation in Italy and Ireland. Large areas of historic loss and damage across the surface of the painting had been reintegrated by the Italian restorers with the application of retouchings in the tratteggio style, also known as rigatino, using a Paraloid-based medium. In some cases, portraits and other significant details in the image were fully reconstructed by the retouchings. Underlying instability required the removal of some of these retouchings during the most recent treatment, but others could be retained if desired. With the help of archival images and documentation, a decision-making model was developed to evaluate the quality and historic value of these retouchings and to determine which to preserve, which to modify and which to remove. Reduction of retouchings often necessitates replacement, and the partial preservation of the historic retouchings brought further factors to bear on the decision-making model for the chromatic reintegration of the painting. A return to the tratteggio technique was chosen for the larger instances of loss compensation in the treatment, albeit with a finer hatching so that the newer reintegration remains distinguishable from the historic one. This was complemented with a pointillist technique over textured fillings for smaller and shallower losses. Furthermore, where blistering and heat damage in the paint layers resulted in uneven topography, a third auxiliary technique was used. The desired texture was found when testing Paraloid-based gels on a mock-up and applied to bring continuity the surface texture in these areas of the painting. With this approach we intend to meet the conservation needs of the object, restore the legibility of the image and retain the evidence of the historic intervention of this founding team of Italian restorers at the National Gallery of Ireland.

Full textAbstract:
Bendigo, where the traditional owners are the Dja Dja Wurrung people, has capitalised on its European historical roots. Its striking architecture owes much to its Gold Rush past which has also given it a diverse cultural heritage. The creative industries, while not well recognised as such, contribute well to the local economy. The many festivals, museums and library exhibitions attract visitors from the metropolitan centre of Victoria especially. The Bendigo Creative Industries Hub was a local council initiative while the Ulumbarra Theatre is located within the City’s 1860’s Sandhurst Gaol. Many festivals keep the city culturally active and are supported by organisations such as Bendigo Bank. The Bendigo Writers Festival, the Bendigo Queer Film Festival, The Bendigo Invention & Innovation Festival, Groovin the Moo and the Bendigo Blues and Roots Music Festival are well established within the community. A regional accelerator and Tech School at La Trobe University are touted as models for other regional Victorian cities. The city has a range of high quality design agencies, while the software and digital content sector is growing with embeddeds working in agriculture and information management systems. Employment in Film, TV and Radio and Visual Arts has remained steady in Bendigo for a decade while the Music and Performing Arts sector grew quite well over the same period.
