Abstract:

The lily is considered one of the highest value cutting flowers as well as is popular to the majority. Bulbs are often imported from the Netherland with an expensive price. Thus, it is difficult to sell commercial lily flowers in the domestic market and international trade. This study focused on mass producing the source of somatic embryos with a high regeneration ability used for the lily micropropagation. Internodes were cultured on MS medium and supplemented with 0.1 mg/l BA and 0.5 mg/l NAA to induce callus, while embryogenic cells reached the highest value at 98.2% before such embryogenic callus was then multiplied on the same media within 5 weeks. The suitable media for somatic embryos regeneration was MS medium supplemented with 0.5 mg/l BA and 0.25 mg/l NAA which after 5 weeks of culture gave us a shoot number of 3.7 shoots/clusters, a shoot height of 87.3 mm, a leaf diameter of 7.7 mm. Multiple shoots regenerated from embryogenic cells were then used as materials for micropropagation. Results showed that the highest data for multiple shoot multiplication was reached in the bioreactor culture system with the maximum number of shoot height (100.25 mm), shoot number (7.1 shoot/cluster) and fresh weight of shoots (1470.94 mg/cluster). The suitable medium for rooting was MS medium supplemented with 0.5 mg/l NAA.

Abstract:

Anthracnose symptoms were observed on soybean (Glycine max (L.) Merr.) cv. Yale in Illinois in September 1996. Lower stems were girdled by lesions that contained black fungal stroma. Colletotrichum coccodes (Wallr.) S. J. Hughes was isolated from surface-sterilized portions of diseased stems incubated on potato dextrose agar (PDA). Cultures produced abundant black sclerotia and acervuli with setae. Acervuli produced straight and fusiform conidia (15 to 23 × 3 to 4 μm) in honey-colored masses. Ovate or long clavate appressoria were formed on slide microcultures. Pathogenicity tests were carried out in the greenhouse on soybean plants, cvs. Panda and Pony at the V4 growth stage, by (i) spraying a conidial suspension (2 ×106 conidia per ml) on seedlings and (ii) placing a mycelial PDA plug above the first two nodes of the stem, previously wounded with a sterile needle. Plain sterile water and plugs without mycelia were used as controls. Six plants per cultivar and per treatment were used. Plants were covered with polyethylene bags for 3 days. Anthracnose symptoms gradually appeared near maturity and plants senesced prematurely with both inoculation methods. Averaged over both cultivars, 100 and 50% of the plants showed symptoms when inoculated with a conidial suspension and mycelial plugs, respectively. Control plants did not have any symptoms. C. coccodes was consistently reisolated from stems, leaves, petioles, and pod peduncles with symptoms, and was not reisolated from noninoculated plants. Seeds collected from plants inoculated with either method showed infection rates up to 14 and 8% on cvs. Panda and Pony, respectively, while seeds collected from control plants showed 0% infection rate. The most common pathogen associated with soybean anthracnose is C. truncatum (Schwein.) Andrus and W. D. Moore, but other species have been reported to cause anthracnose. C. coccodes was reported on soybean in Italy (1). This pathogen has a wide host range and causes serious damage, mostly on solanaceous crops. This is the first report of the presence of the pathogen on soybean in the United States. Reference: (1) G. Conca et al. Petria 4:193, 1994.

Enhanced expression of transforming growth factor β1 in rat thyroid hyperplasia is thyrotropin induced and time dependent. Eur J Endocrinol 1996:134:373–8. ISSN 0804–4643 Forty-three 8-week-old male Wistar rats were studied to evaluate temporal changes of transforming growth factor β1 TGF-β1) mRNA levels in thyroid tissue during pharmacologically induced goiter. Four rats were treated with purified bovine thyrotropin (TSH; Ambinon, 2 mU/day sc) for 7 days before being sacrificed. Thirty-one were treated with propylthiouracil (PTU), added to their drinking water at a concentration of 0.2 g%, and subsequently were sacrificed as follows: five after 1 week PTU-1): five after 2 weeks PTU-2): five after 4 weeks PTU-4): five after 8 weeks PTU-8): five after 12 weeks (PTU-12). In six rats, after 12 weeks of treatment, PTU was withdrawn for 2 months and subsequently started again in three rats which were sacrificed after 2 weeks (PTU-R); the remaining three rats were sacrificed without any further treatment (PTU-R control). Eight rats (control rats) were never treated and served as controls. After sacrifice, blood was drawn for determination of total thyroxine and the thyroid was excised and subdivided into two lobes. Northern analysis for TGF-β1 was performed in one lobe, while histological and immunohistochemical studies were performed in the other lobe. Gene expression of TGF-β1 was induced in TSH- and PTU-treated rats. In TSH-treated rats TGF-β1 gene expression was less detectable than in PTU-treated rats, where it became evident after 2 weeks and remained through weeks 4–8. Gene expression of TGF-β1 was also seen in PTU-R rats, but not in the control and in the PTU-R control. Immunohistochemical analysis showed a different presence and location for the TGF-β1 protein, which appears to be dependent on the time of exposure to mitogenic stimulus. In conclusion, TGF-β1 is produced in response to both a direct (TSH by itself) and indirect (TSH induced by PTU-induced hypothyroidism) cellular proliferative stimulus and is not linked to an adaptative phenomenon secondary to hypothyroidism. The immunohistochemical location of TGF-β1 within the thyrocytes is influenced by mitogen exposure time. A TGF-β1 immunohistochemical evaluation may be important to define exposure time and activity of goitrogenic stimuli.

Abstract:

Laevistrombus canarium, also known as dog conch, is a marine gastropod mollusk widely distributed in the Indo-Pacific region. It is an economically crucial species; however, its population has been declining due to overfishing and overexploitation. In this study, the suitable salinity for juvenile L. canarium was between 20 and 35‰. Diatoms and biological detritus by using flow-water from the fish pool were the most favorable diets for newly metamorphosed and 10 mm juveniles. In the polyculture experiment, L. canarium was cultured with whiteleg shrimp, tilapia, small abalone, purple sea urchin, and collector urchin. Better growth was found in all co-culture groups except with whiteleg shrimp. We also found that the polyculture system with or without substrates significantly affected the growth of juveniles. Additionally, we observed that water temperature was the most crucial factor for growth and survival; a water temperature of less than 10 °C might cause the death of L. canarium. We have proposed a novel polyculture and water-flow method for mass production of L. canarium and evaluated the feasibility and benefits of polyculture with other species. The findings from this work reveal the potentiality of L. canarium in integrated multitrophic aquaculture (IMTA) and its implication for aquaculture and resource restoration.

Abstract:

A partir do conceito de linguagem como ato performativo, proposto por John L. Austin (1962), este trabalho busca expandir tal concepção também para a leitura, entendendo-a não como atividade passiva, mas que age, não apenas sobre os indivíduos, mas em toda a cadeia discursiva. Desconstruindo a dicotomia fala/escrita à luz de Derrida (1972), refletir-se-á sobre a importância de recuperarmos as narrativas indígenas e promover leituras a partir delas como formas de reparação, isto é, como forma de levar adiante uma prática social que povo Canela chama de m’ypé. O presente trabalho se apresenta como um ato de leitura dos processos de reencontro do povo Kotiria, indígenas situados na fronteira entre Brasil e Colômbia, com suas histórias, e também como forma de agir a partir da leitura de tais narrativas, convidando aos leitores a conhecerem mais sobre esse povo e buscar modos apaziguar os séculos de silenciamento de toda uma cultura.

Abstract. The adoption of Conservation agriculture (CA) contributes to sustainable production and its advantages include lower inputs and stable yields. This study was conducted in the research field of Regional Agricultural Research Station, Bhagetada, Dipayal, Doti during 2014 and 2015 to identify the effect of CA on grain yield and income of maize in Maize based cropping system. Both conservation and conventional agricultural (ConvA) practices were evaluated on two maize based cropping systems namely maize-wheat-mungbean (M-W-MB) and maize-lentil-mungbean (M-L-MB). For this purpose two maize varieties namely Raj Kumar and Arun-2 were used. The average productivity of maize under M-L-MB cropping system was 1.6% higher (5.75 t/ha) than M-W-MB cropping system (5.66 t/ha). The average grain yield of maize under CA was 16.7% higher (6.15 t/ha) than ConvA (5.27 t/ha). Rajkumar produced 43% higher average grain yield (6.73 t/ha) than Arun-2 variety (4.69 t/ha). The average net benefit was slightly higher (US$ 597.33/ha) under M-L-MB cropping system than M-W-MB cropping system (US$ 573.89/ha). Similarly, the average net benefit from CA was 102% higher (US$ 783.67/ha) than ConvA (US$ 386.79/ha). Rajkumar variety gave 127% higher average net benefit (US$ 813.49/ha) than Arun-2 (US$ 357.81/ha). The average benefit - cost (B:C) ratio of M-L-MB cropping system was slightly higher (1.72) than the average B:C ratio of M-W-MB cropping system (1.70). The average B:C ratio of CA was 42% higher (2.01) than ConvA (1.41). The average B:C ratio of Rajkumar variety was found 33% higher (1.95) than Arun-2 (1.46). The higher grain yield, net profit and B:C ratio were found in CA practices under M-L-MB cropping system and Rajkumar variety. This study suggests that hybrid maize planting and the adoption of M-L-MB cropping system should be used to increase grain yield and economic performance under CA practices.

Foram preparadas três amostras de feijão preto cozido, sendo uma sem adição de micropartículas de ferro (controle); à segunda foi adicionada quantidade equivalente a 5 mg de ferro, para cada concha média de feijão, e, à última amostra, 10 mg de ferro para cada concha média. Utilizou-se escala hedônica de cinco pontos para avaliação dos atributos. Com base nos resultados obtidos, as amostras controle e 5 mg/porção foram as mais aceitas; houve, porém, pouca diferença em relação à amostra com 10 mg/porção. A boa aceitação do alimento pelos provadores mostra ser viável a fortificação de feijão preto com ferro microencapsulado, podendo ser usado na prevenção e controle da anemia ferropriva.

Abstract:

An intensive exploitation of dog conch Strombus sp. in Tanjungpinang city coastal waters has occurred because the increasing number of fishermen, population growth and demand. In addition, the increasing activities of bauxite mining cause the declining in quality of waters around dog conch, thus providing ecological pressure that endangers sustainability of the dog conch. The purpose of this study was to observe the spawning and development of dog conch in the laboratory. Spawning was done in aquarium with 100 liters of seawater (salinity: 26±1 ppt), with stimulation of spawning performed by changing 90% water volume every day until the female issued the eggs. The female issued the eggs on the third and fourth days of stimulation. Eggs are attached to the wall of the aquarium. Egg cell division occurs after about 2 hours of the egg is released the mother, from one cell into two cells and a row into four cells, eight cells, the sixteen cells, thirty-two cells to multicellular. The embryo develops into a gastrula phase than trochophore phase. Larvae were reared in a tank containing 20 liters of seawater (salinity: 26±1 ppt). Veliger larvae occurred on the fifth day until the eleventh day. Veliger larvae are planktonic, and turn into benthic with a sedentary life in the bottom waters to begin the formation of a thin and transparent shell. The value of water quality parameters during maintenance category feasible: DO of 7.6 to 7.8 mg / L; pH of 8.13 to 8.33; turbidity of 1.97 to 3.90 NTU, salinity of 26.8 to 27.8 ppt; and temperature of 25.8-27.8°C.

Abstract:

AbstractDog Conch (Strombus turturella) has an essential economic value in Bangka Belitung Islands. Allegedly, the population of Dog Conch is decreasing due to overexploitation. The purpose of this study is to provide information related to the distribution of long frequency, growth pattern, age group, recruitment time estimation and life table of Dog Conch. This research took place on the coast of Tukak Village and Anak Air Island, Bangka Belitung Islands. Samples of Dog Conch were taken using 3x3 m2 square. The shell length of Dog Conch found ranged between 18.18 to 77.49 mm, consisting of three age groups. Asymptotic length value (L∞), growth coefficient (K) and theoretical age on zero-length (t0) were 83.94 mm, 0.79/year and -0.152 sequentially. In the first year, Dog Conch grows to 50.18 mm and slows down when it grows older until it is 13 years old. The proportion of high mortality rate was at 1 to 2 years old and 3 to 4 years old or in adult individuals, while the highest life expectancy rate was in the age group of 0-1-year old or young individuals. It indicated that the high mortality rate was in the group in which people use to consume or sell in the marketsAbstrakSiput gonggong (Strombus turturella) memiliki nilai ekonomis penting di Kepulauan Bangka Belitung.

Abstract:

The aim of this study to identify the effective fungicides for controlling major leaf and fruit diseases of Jujube caused by different fungal pathogens. An in vitro experiment was undertaken to screen ten fungicides and two Tannins against six important fungal pathogens of Jujube fruits which were Alternaria alternata, Colletotrichum gloeosporioides, Curvularia lunata, Lasiodiplodia theobromae, Fusarium semitectum and Pestalotiopsis palmarum. Fungicides were Conza 5 EC (Hexaconazole), Folicur 250 EC (Tebuconazole) and Potent 250 EC (Propiconazole), Bavistin DF (Carbendazim), Kasumin 2% liquid (Kasugamycin), Rovral 50 WP (Iprodine), Matco 72 WP (Mancozeb 64% + Metalaxyl 8%), Geneb 80 WP (Mancozeb), Emivit 50 WP (Copper oxychloride) and Evavit 80 WG (Sulphur 80 WG). And two tannins were Chestnut Tannin and Quabracho Tannin. Plain water was used as control. Poison food technique was followed to conduct the experiment. Both Tannins did not show satisfactory inhibition of mycelial growth of any of the six fungal pathogens. The effectiveness of fungicides varied greatly with fungal species. The most effective fungicides were Folicur 250 EC followed by Potent 250 EC, Rovral 50 WP, Conza 5 WP and Bavistin DF. Folicur 250 EC caused 89.52% inhibition of mycelium growth of A. alternata and 100% growth inhibition in other five fungi. In addition, Potent 250 EC inhibited growth of L. theobromae, C. lunata, F. semitectum and P. palmarum by 100% and that of C. gloeosporioides by 91.79%. Complete growth inhibition of F. semitectum and P. palmarum was achieved with Bavistin DF. Furthermore, Conza 5 EC caused 100% growth inhibition in C. lunata and more than 90% in L. theobromae and F. semitectum.Progressive Agriculture 27 (2): 154-161, 2016

Abstract:

Greenhouse studies were conducted to evaluate 5 levels of Mn (0.00025 to 0.1 g.L-1) on Mn toxicity or tolerance of sweetpotato [Ipomoea batatas (L.) Lam] grown in a modified half Hoagland's solution. The presence of oxidized Mn on the roots and leaves was demonstrated by the blue staining test with benzidene and the solubility and bleaching of oxidized Mn in the oxalic-sulfuric acid solution. Both storage root and foliage fresh and dry weights were highest at Mn concn of 0.00025 g.L-1 in the nutrient solution, while fibrous root dry weight was highest with 0.01 g.L-1 Mn in the solution. More Mn accumulated in foliage than in fibrous roots for all levels of Mn evaluated. N, P, and K concn in foliage was highest at a Mn concn of 0.1 g.L-1 Mn in the solution. Foliage dry weight was preserved up to a high Mn level of about 2700 ug. g-1 Mn in tissues, while taht for storage roots was preserved up to a high Mn level of about 1000 ug. g-1 in the tissues. Deposition of oxidized Mn was observed on fibrous roots particularly at the highest Mn levels in the nutrient solution.

Abstract:

Glycemia variability (GV) is an important factor in assessing the quality of glycemic control, as it contributes to the development of micro- and macrovascular complications of diabetes. Currently, there are mathematical methods for assessing GV, obtained using data from professional continuous glucose monitoring (PCGM). PCGM is one of the most modern, innovative technologies that allow assessing the quality of glycemic control and GV in patients with diabetes. The widespread clinical use of PCGM and the interpretation of the data obtained are limited by the lack of generally accepted reference values, as well as by the cost of technology. Reference ranges are needed to interpret the PCGM data in order to improve the quality of glycemic control in patients with carbohydrate metabolic disorders. Aim. Determine the reference ranges for glycemic variability indicators based on the data of professional continuous glucose monitoring to assess the quality of glycemic control. Materials and methods. We studied a population of people without carbohydrate metabolism disorders. A portable Medtronic iPro2 system (USA) was used for PCGM. A sensor was introduced into the subcutaneous fat of the subject, with the help of which 288 glucose measurements were made per day. Calibration was carried out by the subject himself 4 times a day using an individual glucometer. GV parameters were calculated using the Care Link iPro2 Medtronic and EasyGV version 9.0 programs in order to work out the reference ranges. The duration of the study inclusion period was 2 months. The observation period of the participants was 6 days. Results. As a result of the study, the following reference ranges were obtained: the median sensor glucose was 5.0 [4.8; 5.4] mmol/l, TIR – 98.0% [95.0; 99.0], TAR – 0.0% [0.0; 0.0], TBR – 1.5% [1.0; 5.0], GMI – 5.4% [5.3; 5.6], CV – 13.6% [11.6; 15.1], SD – 0.7 mmol/l [0.6; 0.9], MAGE – 1.5 mmol/l [1.2; 1.7], MAG – 0.7 mmol/l/hour [0.6; 0.9], M-Value – 3.7 mmol/l [1.8; 4.4], J-index – 10.4 [9.4; 13.1], CONGA – 4.6 mmol/l [4.5; 5.0], HBGI – 0.7 [0.6; 0.9], LBGI – 2.9 [1.5; 3.2], ADRR – 1.1 [1.0; 2.3]. When conducting a comparative analysis of indicators of glycemic variability, it was found that there were no statistically significant differences depending on age, gender and BMI. Only TBR had statistically significant gender differences (p = 0.007). When carrying out the correlation analysis, only GMI, sensor glucose, M-value, J-index, CONGA, LBGI indicators were statistically significantly correlated with all indicators of the time spent in the ranges. Conclusion. In the course of the study, reference ranges for GV indicators were determined – TIR, TAR, TBR, GMI, CV, sensor glucose, SD, MAGE, MAG, M-Value, J-index, CONGA, HBGI, LBGI, ADRR in the russian population. The obtained values will help physicians in the interpretation of the PNMG data, the wider use of the method in clinical practice, and the expansion of diagnostic capabilities for disorders of carbohydrate metabolism.

In a pot experiment in a phytotron, barley cv. Trumpf seedlings were grown at a light intensity of 6.50 MJ/msuperscript 2 for 40 d and then at light intensities of 6.50, 4.33 or 1.86 MJ/msuperscript 2 with a 14-h day. 134 mg N/plant was applied in 3 dressings at 2 d before emergence and 26 and 48 d after emergence. N uptake was only slightly affected by light intensity. DM yield/plant increased with increasing light intensity. 101 mg DM/mg N was obtained at a light intensity of 1.86 MJ/msuperscript 2 and 175 mg DM/mg N at 6.50 MJ. Higher light intensity accelerated leaf senescence and shortened the photosynthetically active period by restricting N concn. N harvest index was reduced at the lowest light intensity.

Abstract:

ABSTRACT Lobatus gigas, the queen conch, is a central component of Caribbean cuisine but over-fishing of juveniles has threatened the stability of wild populations. Strombid gastropods, upon reaching sexual maturity, cease growing along the shell length axis and continue growing in width via a flared and thickened shell lip. This morphology serves as a useful indicator of an individual's sexual maturity. Here we examine temporal trends in population demographics, size, and morphology of harvested L. gigas individuals over the last ∼1 ky from San Salvador Island, the Bahamas to quantify the dynamics of human-induced stress on the local queen conch fishery. We collected 284 human-harvested individuals from shell middens at seven localities, measured seven morphological variables, and classified the specimens as either adult or juvenile. We randomly selected 64 of these shells for rapid AMS radiocarbon dating in order to establish three geochronological bins: Lucayan (Pre-European invasion, 1492 CE), Modern (∼102 y), and Global (∼101 y). The proportion of juveniles harvested increased significantly from 47% (Lucayan) to 61% (Modern) to 68% (Global) suggesting increasing pressure on the fishery through time. Patterns in body size and morphology diverge between adults and juveniles and are likely the result of an increase in the proportion of harvested juveniles, the selection of smaller juveniles through time, and possibly changes in fishing methods. This size selective predation did not result in the suppression of adult body size as found in other studies. Geohistorical data, such as these, are vital for providing long term ecological context for addressing anthropogenic ecological degradation and are central to the conservation paleobiology approach.

Abstract:

The influences of dried Morchella conica powder (MCP) on quality and sensory properties of sucuks were determined. Sucuks were prepared by adding 0% (control), 1.5% MCP, 3% MCP, 0.02% butylated hydroxytoluene (BHT), and sodium nitrate/nitrite (0.01% NaNO 3 /0.005% NaNO 2 ) and lipid oxidation, colour, texture, and sensory features were analysed. Sucuks with the addition of MCP had much lower (P<0.05) peroxide values than with the addition of BHT and nitrate/ nitrite and the control samples. It was found that the L* and a* values of sucuks with the addition of 1.5% and 3.0% MCP decreased significantly (P<0.05) compared to sucuks with nitrate/nitrite and BHT addition and control samples during fermentation. Hardness and chewiness values decreased with the addition of MCP (P<0.05) during fermentation. The sucuks with MCP added at 1.5% and 3% showed the highest overall sensory acceptance. Thus, proper amount of dried MCP addition may be effective on enhancing sucuk quality properties.

Abstract:

O livro de William L. Westermann, The Slave Systems of Greek and Roman Antiquity, publicado em 1955, é até hoje uma referência para o estudo da escravidão antiga. No entanto, este livro é frequentemente criticado por sua estrutura antiquária e, portanto, pela falta de qualquer abordagem teórica sobre a escravidão no mundo antigo. Esse ponto de vista foi enfatizado principalmente por Moses Finley, com sua obra Ancient Slavery and Modern Ideology (1980), e tornou-se, desde então, um certo consenso na historiografia da escravidão. Este artigo argumenta que tal abordagem negligencia o lugar do livro de Westermann nos debates sobre a história comparada da escravidão que ocorreram nos Estados Unidos durante a segunda metade do século XX. Existem semelhanças entre a tese de Frank Tannenbaum sobre os diferentes níveis de severidade nos sistemas escravistas nas Américas, apresentados em seu Slave and Citizen (1946), e a visão de Westermann acerca dos antigos sistemas escravistas. Essa semelhança é compreensível se levarmos em conta que ambos participaram de seminários sobre a história do trabalho e da escravidão na Universidade de Columbia.

Abstract:

In the present experiments, selective quenching by trinitrophenyl groups as well as steady-state fluorescence polarization and differential polarized phase fluorescence techniques, using three different lipid soluble fluorophores, were used to directly examine the fluidity of the exofacial and cytofacial leaflets of rat small intestinal brush-border membranes. These studies revealed that the fluidity of the exofacial hemileaflet was greater than the cytofacial hemileaflet. Differences in the distribution of phosphatidylcholine and phosphatidylethanolamine, as assessed by phospholipase A2 treatment and trinitrophenylation of aminophospholipids, were, at least partially, responsible for the asymmetrical fluidity of the hemileaflets. Moreover, in vitro addition of benzyl alcohol (final concn 25 mM) preferentially fluidized the exofacial leaflet and concomitantly decreased leucine aminopeptidase activity but did not affect the activities of maltase, sucrase, alkaline phosphatase, or gamma-glutamyltranspeptidase. In vivo addition of the membrane-mobility agent 2-(2-methoxyethoxy)ethyl 8-(cis-2-n-octylcyclopropyl)octanate] (A2C) (final concn 7.5 microM) preferentially fluidized the cytofacial leaflet and increased Na(+)-gradient-dependent D-glucose transport but not Na(+)-gradient-dependent L-leucine transport.

O módulo de elasticidade é uma propriedade mecânica importante no dimensionamento de projetos de estruturas de madeira, logo, a obtenção por meio de diversos métodos necessita ser analisada. Diante disso, este trabalho teve como objetivo avaliar a utilização de técnicas não destrutiva e destrutiva para determinar o módulo de elasticidade longitudinal aparente, levando em conta a relação vão/altura (L/h), e verificar a influência do cisalhamento no módulo de elasticidade, por meio da comparação de ensaios não destrutivos com ensaios de flexão estática. A madeira utilizada no trabalho foi de Toona ciliata M. Roemer (cedro-australiano). Os ensaios não destrutivos foram realizados por meio das técnicas de vibração transversal livre e longitudinal. Concluiu-se que o ensaio de vibração longitudinal é o método mais adequado para obtenção do módulo de elasticidade longitudinal aparente (MOEa,l), pois os esforços cortantes que ocorrem devido às tensões de cisalhamento não influenciaram significativamente na obtenção do (MOEa,l), considerando a variação da relação L/h. Também foi possível concluir que, a relação L/h, atualmente igual a 21 na ABNT NBR 7190 (1997), pode ser reduzida para 20, quando da determinação dos módulos de elasticidade longitudinal aparente e módulo de ruptura por meio do ensaio de flexão estática e vibração transversal livre.

Abstract:

<strong>Some Aspects of Reproduction in Conch Lambis lambis of Yenusi Coastal Waters, Biak.</strong> Lambis lambis is a very popular conch species that has been harvested in all sizes encountered. This condition is very alarming because in the long term, its existence in nature will be reduced because there is no chance to reproduce naturally. This study aims to determine the sex ratio and gonad maturity levels of L. lambis in Yenusi waters, so the appropriate time of harvest can be arranged. Samples were collected every month from January to December 2013. Testing and histological analysis were performed in the laboratory. Samples collected were 99 individus with the number of males 45 individus and females 54 individus. The sex ratio of males and females was 1.0:1.2. Gonad maturity level found included all four stages of gonadal development, from TKG I to TKG IV. Gonadal development showed the process of formation and maturation, and the spawning occured throughout the year, with peak spawning in January until March 2013. The size of the shell length obtained ranged from 4.55 to 13.72 cm indicating over-exploitation. Due to the custom local where residents harvested the conches in all sizes found, sustainable management strategies are urgently needed, including moratorium period when L. lambis is at the peak of spawning, and harvest should only be performed on adult individuals with a minimum shell size of 7 cm, while observing the thickness of the shell and marginal digitations have been formed. <br /><br />

Abstract:

Crystals of a new potassium cobalt(II) iron(II) triorthophosphate salt, KCo3Fe(PO4)3, as well as amorphous nanoparticles of the same material have been produced by hydrothermal reactions, under supercritical water (SCW) conditions, of equivalent quantities of aq. CoCl2·6H2O (2 mol/L) and K4P2O7 (1 mol/L) in concd. HCl in a stainless steel batch reactor at 400450 °C and 2532 MPa. The dark-violet crystals of the new salt have been characterized by single-crystal X-ray diffraction and IR, Raman, and Mössbauer spectroscopy. The Fe(II) in the new orthophosphate salt must derive from leaching of iron from the stainless steel walls of the reactor by concd. HCl under the SCW conditions. The salt crystallizes in the orthorhombic space group Pnnm, Z = 4, with unit cell parameters as follows: a = 9.672(1) Å, b = 16.457(2) Å, c = 6.2004(8) Å, V = 986.97 Å3. Microporous KCo3Fe(PO4)3 exhibits infinite chains of corner-sharing [PO43], [FeO6], and [CoO5] units, which form two large rhombus tunnels, occupied by K+ ions, running parallel to [100] in the unit cell. The vibrational spectra have been interpreted partly on the basis of factor group effects and are in accord with the centrosymmetric structure of the material. The particle sizes of this new nanomaterial and their distribution have been determined by scanning electron micrography and laser scattering particle size distribution analysis, while the amorphous nanomaterial has also been characterized by X-ray powder diffraction and Raman spectroscopy. Key words: crystal structure, vibrational and Mössbauer spectra, orthophosphate, nanomaterial.

Abstract.Knowing that resilience is determined by genetic and environmental factors upon the culture of origin, age and gender of the individual (19, 4, 6, 7, 5, 14) and that the issue of productivity is seriously notorious (18, 8 and 3) in the current world of serious competitiveness and insecure survival, it’s prudent to evaluate the relationship between resilience and productivity. Our research, in development, aims to build a new model of psychotherapeutic intervention to develop individual’s resilience and productivity, recognizing which resilience’s categories contribute the most to increase each individual productivity, adapting the interventional model considering the individual resilience skills to develop or acquire. Our non-probabilistic sample, by convenience, comprises workers of both genders, with 35 years old mean. Regarding the business world is of vital importance the employee’s technical competence, as well as their emotional and social skills, since are those that would respond in crisis situations and/or in adaptational urgency (18, 12), therefore focus of our interventional model, with the following psychotherapeutic techniques that had emerged as fundamental to increase productivity: the awareness and promotion of self-esteem and self-confidence, autonomy and independence, internal locus of control, patience, initiative, determination, tenacity and empathy (team spirit and belonging); expectations management and setting realistic goals (realistic notion of control, focusing on the solution and skills enhancement) and finally emotion/stress and negative feedback management (critical situations exposure and training).Keywords: Resilience, Stress and Productivity.Resumo.Sabendo que a resiliência é determinada por factores genéticos e ambientais, mediante a cultura de origem, idade e género do indivíduo (19; 4; 6; 7; 5; 14) e que a questão da produtividade é de séria retumbância (18; 8; 3), no mundo actual de séria competitividade e insegura sobrevivência, torna-se prudente avaliar a relação entre resiliência e produtividade. A nossa investigação, em fase de desenvolvimento, visa a construção de um novo modelo de intervenção psicoterapêutica que desenvolva a resiliência e produtividade de um indivíduo, reconhecendo em que medida as categorias da resiliência contribuem para a produtividade de cada indivíduo, adequando o modelo consoante as competências da resiliência a desenvolver ou adquirir. A nossa amostra de conveniência não probabilística compreende trabalhadores de ambos os géneros. No que concerne o mundo empresarial é de vital importância a competência técnica do trabalhador, assim como as suas competências emocionais e sociais, uma vez que serão estas últimas as que responderão em situações de crise e/ou de necessidade de adaptação (18; 12), e portanto em foco no nosso modelo de intervenção que conta assim com as seguintes técnicas psicoterapêuticas que emergiram fundamentais para o aumento da produtividade: de consciencialização e promoção da auto-estima e autoconfiança, autonomia e independência, locus de controlo interno, paciência, iniciativa, determinação, tenacidade e empatia (espírito de grupo e de pertença); de gestão de expectativas e criação de objectivos realistas (noção realística de controlo, com enfoque na solução e valorização das competências) e finalmente de gestão de emoção/stress e feedback negativo (exposição e treino em situações críticas).Palavras-Chave: Resiliência, Stress e Produtividade

Abstract:

O desgarramento foi postulado por Decat (1999, 2011), com base numa análise funcional-discursiva, afirmando que algumas orações entre as tradicionalmente chamadas de ‘subordinadas’ pela tradição gramatical podem ocorrer soltas ou sozinhas. Instigado pelo fenômeno, este artigo realiza uma descrição prosódica de orações desgarradas e correlaciona-a a reflexões referentes aos fraseamento prosódico no Português do Brasil. Para isso, leva em conta resultados de Tenani (2002) e Serra (2009), concernentes à estrutura entoacional de orações adverbiais e aos correlatos acústicos do fraseamento no PB, respectivamente, que revelam ser o contorno entoacional L+H*H% relativo a sintagmas entoacionaisn (IPs) hierarquizados e a pausa ser a pista mais robusta no fraseamento de IPs. Foram analisados os parâmetros acústicos duração, pausa e contorno de F0 em 900 orações adverbais – 450 anexadas à oração matriz e outras 450 lexicalmente idênticas, desgarradas, produzidas por cinco informantes oriundas do estado Rio de Janeiro. Os resultados demonstram que a maioria das orações adverbiais produzidas em conjunto com a oração matriz foram delimitadas por contornos melódicos com fronteira baixa (72,7% dos dados - 38,5% de L+H*L% e 34,2% de H+L*L%), ao passo que o contorno L+H*H% esteve presente em 27,3% delas. No que se refere às orações desgarradas, completas, o contorno L+H*H% foi majoritariamente produzido (83,5%). Com isso, postula-se que o contorno L+H*H%, referido como “continuativo” na literatura de base prosódica (Gonçalves 1997; Cunha, 2000; Tenani 2002) só traria a ideia de continuidade quando o IP for fraseado sem a saliência de outra pista prosódica.

Abstract:

O presente artigo tem por objectivo compreender o processo de ensino-aprendizagem em Língua Portuguesa no Ensino Secundário Geral, tendo em conta os alunos provenientes do Ensino Bilingue, em Moçambique. E, especificamente pretendeu-se avaliar o impacto do Ensino Bilingue no Ensino Secundário Geral onde as aulas são ministradas em Língua Portuguesa e propor algumas políticas educacionais a fim de minimizar as desigualdades sociais entre os alunos provenientes do ensino bilingue e os do monolingue. Para alcançarmos estes objectivos, desenvolvemos uma pesquisa de carácter descritivo que consistiu na observação e análise dos factos colhidos da realidade, procurando classificá-los, explicá-los e interpretá-los. Realizada a pesquisa concluiu-se que os alunos provenientes dos dois sistemas de ensino apresentam grandes dificuldades de comunicação em língua portuguesa. Associando-se a isso, estão também os professores que apresentam muitas deficiências no uso de métodos que possam levar os alunos a desenvolverem as quatro habilidades linguísticas (ouvir, ler, falar e escrever), devido a uma série de factores, com destaque para a falta de uma pré-formação nas didácticas de ensino do Português como L2 e ausência de capacitações sistemáticas.

Abstract:

O cultivo da oliveira (Olea europaea L.) tem se intensificado no estado do Rio Grande do Sul, que hoje conta com mais de 3500 hectares plantados e 145 produtores, sendo o maior produtor do país. Contudo, os olivicultores ainda enfrentam diversas dificuldades, entre as quais as de cunho fitotécnico, principalmente aquelas relacionadas ao manejo de pragas e doenças. O objetivo deste trabalho foi gerar conhecimentos básicos e aplicados à cultura da oliveira referentes a espécies de cochonilhas (Hemiptera; Coccoidea), controle de cochonilhas potencialmente pragas e controle de Colletotrichum associado à antracnose em oliveira e, assim, contribuir para o desenvolvimento da cultura no estado.

Abstract:

Resumo: Este texto serve como introdução a "Os estudos sociais e a mudança social no Brasil", primeiro capítulo do relatório enviado à CAPES por Luiz de Aguiar Costa Pinto em 1955 a respeito da situação da sociologia no Brasil. A fim de situar o leitor, além de reconstituir brevemente alguns aspectos da trajetória de Costa Pinto, também sugiro algumas chaves de leitura que permitam dar conta das especificidades deste texto em relação aos demais "balanços" da sociologia realizados na década de 1950. Neste sentido, assinalo como a experiência do Estado Novo, que impactou fortemente nos rumos da vida universitária do Rio de Janeiro, torna-se uma componente central dos argumentos desenvolvidos por Costa Pinto, que a analisa através da noção de "marginalidade estrutural".

Abstract:

Oxygen radicals play an important role in the mechanism of acute lung injury. The 21-aminosteroid lazaroid, U-78518F, is a potent antioxidant. We examined the effect of intravenous U-78518F on acute lung injury in septic guinea pigs over 8 h. The experimental groups (n = 6) were 1) saline control, 2) Escherichia coli (2 x 10(9)/kg i.v.), 3) pretreatment (U-78518F 5 mg/kg bolus + 1 mg.kg-1 x h-1, 15 min before E. coli injection), and 4) posttreatment (U-78518F 30 min after E. coli injection). We measured wet-to-dry weight ratio (W/D) as an index of pulmonary edema and concentration ratios of 125I-labeled albumin in lung tissue and bronchoalveolar lavage fluid compared with plasma (L/P and BAL/P, respectively) as indexes of lung protein fluxes. In septic guinea pigs, pretreatment with U-78518F attenuated W/D, L/P, and BAL/P and posttreatment attenuated W/D and BAL/P (P < 0.05 for each). Furthermore, we studied the effect of U-78518F on human neutrophil oxygen radical production (ORP) by using flow cytometry to assess intracellular ORP and lucigenin-dependent chemiluminescence to assess extracellular ORP. Neutrophils (5 x 10(5) were stimulated with 0.5 micrograms/ml of phorbol myristate acetate. With flow cytometry, we measured intracellular ORP, cross-sectional cell area, and degranulation in neutrophils. U-78518F (minimum concn 1.0 microM) decreased intracellular ORP (n = 4; P < 0.05) when the dihydrorhodamine 123 assay was used. U-78518F (minimum concn 1.0 microM) inhibited phorbol myristate acetate-induced neutrophil chemiluminescence (n = 4; P < 0.05).
