Повний текст джерелаFirstly, in order to define and create a typology of existing dictionaries concerning sport, we identified more than 400 sports and among them we defined more than 200 sports (those which were the less common around the world). We then classified them into 19 thematic groups, which classification has been submitted to a technical review. All these sports have allowed us to reference near to 500 dictionaries from which we have been able to identify the various criteria which enable the writing of specialty dictionaries. We have chosen the most relevant and suitable criteria to write our "Dictionnaire du rugby – L'Ovalie dans tous ses sens".Secondly, we described our approach concerning this specialty dictionary by specifying our thought and choices related to, on the one hand, the subject and, on the other hand, the philosophy of a work of this kind. This reflection covered the objective of such a dictionary, the targeted public, the way it has been written and its structure. Furthermore, we considered the treatment of the term rugby (and of its vocabulary) in about fifteen books. Finally, we proposed our methodology for the writing of the "Dictionnaire du rugby – L'Ovalie dans tous ses sens" focusing in particular on the protocol of writing, the creation of a graphic chart, the presentation of the paratext, the conception of a nomenclature, and on the different steps of the writing and the rectifications

Повний текст джерелаОбзор современных технических средств и технологий контроля качества элементов и соединений трубных колонн показывает, что, не смотря на широкое использование в нефтегазовой области методов неразрушающего контроля, вопрос комплексного контроля стальных обсадных труб (СОТ) остается нерешенным. По данным Американских нефтегазовых компаний в США на трубных базах после проверки обсадных труб на соответствие действующим стандартам отбраковывается до 20% общего количества проверенных труб. Учитывая то, что аварии с обсадными трубами составляют 7-8% всех аварий в бурении, на их ликвидации расходуется свыше 10% времени, которое приходится на ликвидацию аварий всех видов, задача разработки и внедрения методов и средств контроля СОТ является, безусловно, актуальной. Входной контроль СОТ с помощью разработанных технических средств и технологий обеспечит недопущение к эксплуатации труб с дефектами, а также позволит формировать обсадную колонну в соответствии с фактическим техническим состоянием СОТ. ель работы состоит в разработке методов, технических средств и технологий автоматизированного контроля стальных обсадных труб в условиях баз производственного обслуживания нефтегазодобывающего предприятия. Практическое значение полученных результатов состоит в том, что разработанные технические средства и технологии реализованы в комплексной установке контроля основных параметров СОТ, внедренные в производство. Разработанные методы и технические средства прошли промышленные испытания на базе производственного обслуживания Хрестищенского УБР ДК "Укргаздобыча" и в Научно-производственной фирме "Зонд".

In the present study, the morphological and enzymic characters of Halophila ovalis (R.Br.) Hook.f. from Taiwan and Peng-Hu were investigated. The species is rather variable in morphology and with significant differences between 10 populations. In the analyses of isozymes, 7 among the 10 loci are polymorphic with 41% in avarage. The observed value of heterozygosity ranges from 0.000 to 0.250, while the expected value of heterozygosity ranges from 0.000 to 0.311. The number of alleles per locus ranges from 1.10 to 1.60, while the effective number of alleles per locus is from 1.012 to 2.952. Results of Chi-sqauare and F-tests showed that heterozygosity of Halophila ovalis is rather low and far from the Hardy-Weinberg Equilibrium. According to the pattern of genetic variability, 32.25% of variation occurs between populations while 67.75% is present within each population. Obviously, interpopulational genetic exchange is rather low, and the geological location is not correlated to genetic distance. In summary, the genetic variation of Halophila ovalis is higher than other seagrasses and freshwater plants, such high differentiation and variability may be caused by its potential to adapting diversed habitats and wide distribution.

Thalassia hemprichii and Halophila ovalis are two widely distributed seagrasses in Indo-West Pacific Ocean. In this study we investigated their dispersal mechanisms. Threehypotheses are proposed and tested: 1. dispersal by current 2. transported by birds, 3. transported by fishes. I used plants at different stages-adult plants,seedling,fruits and seeds to test these three hypotheses.Samples of Thalassia hemprichii and Halophila ovalis were collected from Dongsha Atoll in 2013 and 2014.Adult plants of Thalassia hemprichii could remain floating and survive for at least 2 months, longer than the seedlings which could have one month floating stage if unattached to substrate. Fruits of Thalassia hemprichii could remain floating for two weeks and release germinable seeds., but germination rates decline with longer floating time. Adult plants of Halophila ovalis could only float for one weeks before dying. The seeds of Halophila ovalis could pass through animal gastrointestinal tracts and remain competent for germination ,but seeds of Thalassia hemprichii could not. These two seagrasses use different dispersal mechanisms.

In recent years, climate change, coastal development and marine pollution are causing dramatic decline of marine ecosystems, especially seagrass ecosystem which locates exclusively in subtidal zone. Understanding their dispersal mechanisms and connectivity are very important for restoration, conservation and management of seagrasses. Halophila ovalis (R. Brown) J. D. Hooker is a wildly distributed species in the Indo-Pacific. Around Taiwanese water, it can be found in Tainan, Penghu Islands and Dongsha Atoll. Previous literature indicated their fruits and seeds which digested by birds were have a much higher germination rate. Therefore, the biotic vector such as migratory birds may play an important role on their long distance dispersal. If the migratory shore birds are responsible for carrying new recruits from different geographic populations (countries), a temporal genetic structure shift could be expected. In this study, we performed the sampling for consecutive years in Penghu, Qigu and Dongsha Atoll to reveal a possible temporal population structure shift to test the biotic dispersal hypothesis. A temporal genetic structure shift between 2017 and 2018 was observed, and all the populations have unique genetic structure. This indicates low dispersal capacity and local adaptation may play an important role on shaping the genetic structure of H. ovalis among sites within year, however, temporal genetic structure shift between years might result in fast turnover rate of seed bank.

Seagrass, as marine angiosperms, plays an important role in coastal ecosystems. Understanding the population connectivity between geographic regions is important for their future restoration. Halophila ovalis is distributed in the Indo- West Pacific and can produce recruits through both asexual and sexual reproduction. The former uses rhizomatous rametes or rhizome fragments to disperse, the latter uses seeds to achieve the purpose of expanding their population. Since it’s fruits and seeds have negative buoyance and the seeds of H. ovalis could pass through the digestive tract of waterfowls and lead to higher germination rates than un-ingested controls. Therefore, biological vectors (i.e. migratory birds) may be a possible mechanism for long-distance dispersal. In this study, we collected 625 samples from 23 sites to understand the population connectivity of H. ovalis in the Indo-West Pacific. ITS and microsatellite loci were used to barcode and reveal the population connectivity pattern, respectively. According to the result, 432 samples of H. ovalis from 17 sites were used in this study. High level genetic diversity was found within 17 populations. The results of FST analysis showed that significant genetic differentiation was found among H. ovalis populations in the Indo- West Pacific. The results of STRUCTURE analysis showed that most of H. ovalis populations in the Indo- West Pacific possess unique genetic composition. Indicate that the gene flow between H. ovalis populations in the Indo- West Pacific is limited, therefore, long-distance dispersal by migratory birds is unlikely the main mechanism for shaping their connectivity pattern, and we suggest at least three cryptic species may occur within its distribution.

Luciola ovalis Hope is one of the aquatic fireflies commonly distributed in Taiwan. Based on the present obervations by ficial rearing, its adult longevity was found to be ca. 10 days; pupal period, ca. 7 days; larval stage, ca. 90 days and egg period, ca. 25 days. It took about 120 days to complete the whole life cycle. The larvae could feed on at least 10 smallils as their food. The matured larvae climbed up from water to the ground for pupating in a soil chamber. Each female could lay about 100 eggs in her life. Artificial rearing of the firefly with a river snail was carried out in a glass tank equipped with an air pump andting lamps. The rearing conditions were set up at 22.5 ±2.5℃, water temperature; and L:D=14:10, photoperiod. Each instar was judged by measuring body length and prothorax length and width of the reared larvae. The larval survival was recorded 80s after rearing and was found to be 94.6% by the shallow rearing tank and 91.2% by the deep tank. The period for 50% adult emergence was 148 days by the shallow tank and 167 days for the deep one. An artificial diet was developed for rearing this firefly. The diet is composed of above 50% animal proteins to which were added fat, dextrose, vitamins, starch and sweet rice powder. The rearing on this diet was conducted in a plastic tray equipped with an air pump. The results showed that the larvae took 208s to reach 50% adult emergence. This artificial diet wasfor rearing 4th to 6th instar larvae than for 1st to 3rd instars.

The population distributions of Amblyseius ovalis (Evans) and Tetranychus urticae Koch were evaluated by the values of indices and their distribution─uniform, random, and aggregative distribution types, according to the hypotheses of (1) index of dispersion (ID), (2) Green''''s coefficient of dispersion (Cx), (3) Lloyd''''s mean crowding index (mc), (4) Lloyd''''s patchiness index (mc/m), (5) Morisita''''s coefficient of dispersion ( Iδ, Iβ), (6)Taylor''''s power law regression with intercept (㏒a) and sloped (7) Iwao''''s patchiness regression (α, β). The frequencies of distribution types of mites'''' populations mearsured by week or by stages were accordingly rearranged and utilized to assess the appropriate type of distributions. A. ovalis and T. urticae population in the field were either aggregative or random type. Predator-prey relationship was demostrated by A. ovali feeding on T. urticae. The responses of daily predation rate and predation rate curve of A. ovalis on 8 prey densities of T. urticae showed a Holling'''' s typeΠ and type Ⅲ responses─functional responses of predator. Non-linear regression model was used to fit daily predation rates on the different prey densities and found 43 functional response equations which included the independent variables of (1) predator''''s stages, sexes, and feeding history prey'''' s species, stages, and sexes, (3) habitat substrates and sizes, and (4) temperatures. The fitted regression equations were used to find out the theoretical attack rates (a) and handling time (Th) under different tested conditions. Those a'''' s and Th''''s were also variate with the tested conditions by which the interactions and relations between the predator and the prey were interpreted and discussed.

Both male and female silverleaf whitefly (SLWF), Bemisia argentifolii Bellows and Perring, feeding on cucumber, matured in 19.7 ~ 19.9 days at 28 ℃. Adult females laid 101 eggs in 25.6 days of oviposition period with a rate of 3.64 eggs per female per day. Peak reproduction rate was found at either day 4 (6.52 eggs/female/day) or day 8 females (6.02 eggs/female/day). SLWF population multiplied 101.5 times in a mean generation time of 29.6 days with 0.156 eggs/female/day of intrinsic rate of increase. The strategies successes used by SLWF for host adaptation, if not on all kinds of hosts but at least in cucumbers, are maturity rate and adult longevity instead of reproduction rate. Feeding on cucumber pollen, 68.8% Amblyseius ovalis (Evans) females developed into adults, but none on honey-dew of silverleaf whitefly (Bemisia argentifolii, SLWF). Females of A. ovalis deposit most of their eggs on the top of chaeta of underside of leaves with 26.8 eggs per female in an average of a 24.4 day life span. The daily reproduction rate per female is 1.1 eggs. Two highest daily reproduction rates (2.0 ~ 2.1 eggs/female/day) of females were found at female aged 4 and 8 ~ 10 days; the female sex ratio (female/ (female + male)) of offspring was 0.68. A total of 16.7% females feeding on cucumber pollen did not reproduce eggs, but the females resumed egg reproduction when first instars of SLWF were supplied. A. ovalis feeding on eggs, 1st and 2nd instar of silverleaf whitefly, Bemisia argentifolii has shorter developmental duration, better survival rate, and longer longevity. All the predator females reproduced eggs when they fed on the 1st or 2nd insatr of SLWF, but only 50.0 % did on SLWF eggs and 61.1 % did on eggs and pollen. Feeding on 2nd instar of SLWF with pollen, A. ovalis females gave the highest fecundity, while A. ovalis feeding on eggs with pollen added gave the lowest one. The daily reproduction rates (0.1 ~ 1.3 eggs/♀♀/day) of A. ovalis were significantly varied due to stages of SLWF preys. The net reproductive rate (Ro) of 4.28 ~ 21.86 and the intrinsic rate of increase (rm) of 0.140 ~ 0.288 and generation time (T) of 10.41 ~ 12.17 days were found while A. ovalis fed on tested stages of SLWF. The larvae of predator didn’t prey on SLWF, but other stages (protonymph, deutonymph and female) foraged an average of 43.9 first instar or 16.7 second instar of SLWF in the life-time of A. ovalis. Deutonymphs and females of A. ovalis showed a Holling typeⅡfunction when it fed on eggs and immature stages of SLWF. Female of A. ovalis retained the highest daily predation rate (predation plateau) 5.88 nymphs in 4 cm2 leaf disc at prey density of 28 1st instar nymphs in 24 hours (a: 0.6286, Th: 0.1723). A. ovalis female showed highest daily reproduction rate of 1.0 ~ 1.5 eggs/female/day when offered 24 ~ 32 nymphs in 4 cm2 leaf disc. Consequently, the stage-specific effects of SLWF were found and evaluated from the response of developmental duration, pre-oviposition period, oviposition period, longevity, fecundity, sex ratio of progeny, and intrinsic rate of increase of A. ovalis. The variations on functional and numerical responses of A. ovalis were also correlated to the different B. argentifolii stages. Feeding on SLWF, A. ovalis completed its maturity with high survival rate and reproductive rate. Furthermore, the development rate, longevity and fecundity of A. ovalis were enhanced when the additional cucumber pollen was added. We conclude that A. ovalis prefers SLWF 1st and 2nd instars later instead of eggs; therefore, SLWF 1st and 2nd instars are suitable food for population growth of A. ovalis. The vertical distribution of Bemisia argentifolii was stage-specific by eggs, nymphs and adults on cucumber. Adults and eggs appeared at upper leaves, while the 1st & 2nd instar nymphs and 3rd & 4th instar nymphs appeared at middle and lower leaves, respectively. A high density of active stages of Amblyseius ovalis was attracted by the 1st and 2nd nymphs of whitefly which aggregated on the middle leaves. The spatial distribution patterns of B. argentifolii and A. ovalis were aggregated according to Taylor’s Power Law (a: 0.401, b: 1.257 and a: 0.311, b: 1.074) and Iwao’s Mean Crowding Regression (α: 1.325, β: 1.090 andα: 1.477, β: 1.014). Population densities of both predacious mite and whitefly did not depend on temperature in summer season (Jun. ~ Sep.) but did in the period of October to May. A. ovalis or B. argentifolii did not positively correlate with weekly precipitation. Population density increases of A. ovalis and B. agrentifolii on cucumber appeared highly synchronized (Y = 0.4458x + 0.4123, R2 = 0.7740, p < 0.0001). Apparently, the A. ovalis was an important density dependent factor of B. argentifolii on cucumber. A. ovalis showed same degree of effectiveness as chemical measures did to suppress SLWF population increases on cucumbers. The cucumber yield was 1.74 times on A. ovalis released plots than the no predator released plots. In order to gain a better suppression on SLWF density and a higher yield of cucumber fruitage, we released A. ovalis of 7 adults/plant or 14 adults/plant. Inoculative release of A. ovalis in cucumber field could increase the cucumber yield at the lower population density of SLWF. We suggest that A. ovalis can be adopted for integrated control of SLWF with carefully selected pesticides.

Abstract Hippidae belongs to the Infraorder Anomura, Order Decapoda, Class Malacostraca, Subphylum Crustacea. There are two genera and six species of hippid crabs of Taiwan in this study, including Hippa adactyla Fabricius, 1787, H. admirabilis (Thallwitz, 1892), H. marmorata (Hombron & Jacquinot, 1846), H. ovalis (A. Milne-Edwards, 1862), H. truncatifrons (Miers, 1878) and Mastigochirus gracilis (Thallwitz, 1892). H. marmorata is a new record from Taiwan. The morphological characters, identification keys, line drawings and color photographs of these species are provided as useful information for the studies in the future. There are approximately 27 known hippid species in the world. The hippids from Taiwan is about 22.2 % of the world or 35.2 % of the Indo-West Pacific. The hippid diversity of Taiwan is the highest in the Indo-West Pacific. The reproductive ecology of H. ovalis from the intertidal zone near the estuary of Nan-ao River, Yilan County was studied. A total of 2029 specimens (1317 females and 712 males) of H. ovalis were collected from November, 2008 to December, 2009. Carapace length of female ranged from 9.2 to 36.9 mm, with mean carapace length 21.8±3.6 mm. Carapace length of male ranged from 11.0 to 26.1 mm, with mean carapace length was 18.8±2.0 mm. There is significantly difference (p < 0.05) in the ratios of carapace length and carapace width, carapace length and body weight between the sexs according to the analysis of covariance. The monthly sex ratios were significant difference (p < 0.05) from 1:1 in Chi-square test. Females outnumbered males in each monthly sample. H. ovalis are multiple spawners and reproduce all year round. Its main reproductive season is from May to October, with a peak in June and July. The fecundity and mean egg diameter (non-eyed) were 660 to 16817 eggs and 527±28 μm, respectively. The carapace length at first sexual maturity of female was around 18.1 mm, and male was around 16.0 mm. The reproductive activity of H. ovalis was significantly affected by air temperature from the multiple regression analysis. H. ovalis were parasitized by Halysiorhynchus macrocephalus (Shipley & Hornell, 1906) larva which belongs to the Phylum Platyhelminthes, Class Cestoda, Order Trypanorhyncha, Family Mixodigmatidae. H. macrocephalus is a new record from Taiwan. There is no evidence showing that how the parasite affected the reproduction of its host, H. ovalis.

The coverage of seagrass Halophilaovalis in Citou Bay is the highest of all the seagrass meadows in Penghu. It has high ecological importance because there are abundant species of creatures. However, the distribution of the seagrass meadow is shrinking because of the influence of human disturbance and environmental changing. In this study, it revealed that the coverage dropped twice in a year, during July to August and December to February. The third pair of leaves was obviously smaller during the high-water temperature period of July to August. There were two peaks of biomass, rhizome length, and leaf amount during April to July and November to January; moreover, blooming and fruiting periods appeared as well. The ratio of shoot system to root system were 0.49±0.11. There were four undulations of the curve showed that it has a short life cycle and rapid growing speed. The length of rhizome grew longer during October to January for anchoring in the monsoon season. There was the best growth rate under the salinity of 25 and 35ppt and the temperature of 30℃. After germinating, the cotyledon extended and radicle stretched, and then the first to the fifth leaf and the first pair of buds grew consecutively. Low salinity would not only promote the germination rate but also shorten the time frame of germination. There was no statistical significant difference of germinate rate between the group with and without artificial light. However, the average germination days of the group without artificial light was obviously shorter than the other. Providing light to the young seedlings would be helpful on growing more leaves. Considering the growth of young seedlings, the best germination condition would be under the salinity of 10ppt with light, although the best germination index was the condition under the salinity of 5ppt without light. Therefore, the best preservation condition for seagrass seeds was 10℃ and 35ppt. Keywords: Halophila ovalis, biomass, germination

ABSTRACT The development, life table and predation rates of the predatory mites Neoseiulus womersleyi and Euseius ovalis feeding on four tetranychid mites and two kinds of pollen was studied in a chamber at 25°C, 75±5% RH and 16:8 (L:D) photoperiod. Immature stages of N. womersleyi feeding on Tetranychus urticae and T. kanzawai had shorter development duration (4.71 and 5.02 days for females, 4.77 and 5.19 days for males, respectively) than those feeding on other food sources. Immature stages of E. ovalis females feeding on Oligonychus mangiferus and T. urticae developed in 4.99 and 5.13 days, respectively, the shortest developmental duration measured. Immature stages of E. ovalis males feeding on O. mangiferus and T. urticae developed in 5.12 and 5.37 days, respectively. The longevity of N. womersleyi males (13.31 to 14.51 days) and females (17.67 to 21.81 days) feeding on T. urticae, T. kanzawai or maize pollen was longer than the longevity of N. womersleyi feeding on O. mangiferus, P. citri or loofah pollen. Euseius ovalis males (12.91 to 16.74 days) and females (16.24 to 23.77 days) feeding on O. mangiferus, T. urticae or maize pollen lived longer than E. ovalis males and females feeding on T. kanzawai or Panonychus citri or loofah pollen. Among all of the food sources tested, the fecundity of N. womersleyi was high (33.57 eggs/female) on T. urticae, but low on P. citri (17.63 eggs/female), whereas E. ovalis was high (35.86 eggs/female) on O. mangiferus and low (8.89 eggs/ female) on T. kanzawai. Sex ratio differed among food sources and ranged from 0.67 to 0.78 for N. womersleyi and from 0.68 to 0.78 for E. ovalis. In addition, female sex ratios of N. womersleyi and E. ovalis in the field also changes, higher sex ratio in June, July and November, and lower sex ratio was found in August, September and December. The highest net reproductive rate (R0 = 24.86 offspring/individual) and intrinsic rate of natural increase (rm = 0.254/day) were found in N. womersleyi feeding on T. urticae and T. kanzawai, respectively; the lowest R0 (9.88 offspring/individual) was recorded on O. mangiferus and the lowest rm (0.179/day) was on loofah pollen. When feeding on O. mangiferus, E. ovalis had a higher R0 (26.46 offspring/individual) and rm (0.256/day) than those fed on other food sources. Neoseiulus womersleyi immatures consumed 9.73 T. urticae eggs, 13.53 larvae, or 11.57 protonymphs, while gravid females consumed 12.13 T. urticae eggs, 14.37 larvae, or 12.07 protonymphs daily. Female N. womersleyi consumed a total of 218.12 T. urticae eggs, 260.85 larvae, or 222.33 protonymphs, while male N. womersleyi consumed a total of 96.39 T. urticae eggs, 112.23 larvae, or 99.65 protonymphs. When O. mangiferus larvae or protonymphs were offered to E. ovalis, immatures consumed 18.57 larvae or 17.47 protonymphs. Gravid females consumed 16.83 larvae or 12.83 protonymphs daily, with a total of 330.68 larvae or 252 protonymphs. Adult E. ovalis males consumed fewer O. mangiferus larvae (107.69) or protonymphs (91.51) than females. Conversion rate of predation to reproduce was expressed as “Food-reproduction exchange rate” of N. womersleyi was lower on T. urticae than on T. kanzawai. E. ovalis showed a higher food-reproduction exchange rate on O. mangiferus than on T. urticae.
