The Effects Of Different Aeration Rates In The Larval Rearing Of Some Cyprinidae Species

A study was undertaken t o develop an appropriate technology offish seed production in the tropics in order to overcome the constant water scarcity and its high operational cost . Accordingly , three experiments were carried out at the Fish Hatchery Unit , Faculty of Fisheries and Marine Science, Universiti Pertanian Malaysia to determine the optimum aeration rate and stocking density for fish larval rearing .In the first experiment , one hundred larvae of Puntius gonionotus , Cyprinus carpio , and Carassius auratus were reared for 20 days respectively in tanks with four different aeration rates ; 0,50, 500, and 5,000mL /min . From the results of the first experiment , the aeration rat es of 0 and 5 0 mL / mi n , 5 0 and 500 mL/min , and 50 mL /min were found to be the optimum rates for the larval rearing of Puntius gonionotus , Cyprinus carpio , and Carassius auratus respectively

Erratum for Vol. 69, No. 6, pp339-348, Anxiety and Feelings toward Their Baby among Pregnant Women with Uterine Leiomyomas

Pregnant women with uterine leiomyomas may experience anxiety toward their pregnancies and unfavorable feelings toward their infants. From March to July 2010, we distributed anonymous self-recorded questionnaires to 200 pregnant women who visited Okayama Central Hospital for an antenatal check-up after informed consent was provided, and 132 women (23 pregnant women with uterine leiomyomas) were included in our study. Among the multiparous women in their first trimester, the women with uterine leiomyomas had a higher rate of anxiety than those without uterine leiomyomas. ʻAvoidanceʼ scores on the Feeling Toward the Baby Scale were significantly higher in the leiomyoma group. The conflict index scores tended to be higher in the leiomyoma group. A multivariate analysis revealed no factors associated with trait-anxiety scores, whereas high state-anxiety scores were correlated with low age;however, there was no correlation between these scores and uterine leiomyomas. Although no factors were associated with State-Trait Anxiety Inventory (STAI) and approach scores toward the baby, avoidance and conflict index scores were associated with the existence of uterine leiomyomas. In pregnant women with uterine leiomyomas, efforts should be made to reduce anxiety in the first trimester, and support should be provided to help these women develop positive feelings toward their babies

Climatological study on large-scale situation associated with the cool summer around the Northeastern Japan in 1990s (in comparison with that in 1970s)

It is pointed out by the previous studies that the Baiu front tends to stagnate around the Japan Islands even in midsummer season in 1990s, although the global warming is going on. The present study examined the climatological features of the appearance of daily fronts on the surface weather maps and the large-scale factors associated with the activity of the polar frontal zone to the north of the Baiu frontal zone based on the observational data in the summer of 1971-2000. It was found that the midsummer when the Baiu front tends to stagnate around the Japan Islands appeared rather frequently in 1970s as in 1990s. However, the baroclinicity around the Eurasian polar frontal zone was stronger in 1970s than in 1990s. Thus while the fronts around the Japan Islands in midsummer were greatly due to the southward invasion of cold front associated with the disturbances on the polar frontal zone in 1970s, the Okhotsk High tends to stagnates to the northeast of the fronts around the Japan Islands in 1990s

Changes in Shear Force and Inward Pressure inside Plug-fit Sockets Due to Flexion and Extension of the Elbow Joint

This study measured shear force and pressure of prosthesis sockets and compared sockets made from conventional hard acrylic resin with soft material. In addition, we also examined how the acrylic resin of the socket influences the decision to put on an elbow system prosthesis. We found that the soft socket extended the range of motion of the elbow joint and permitted movement of the soft tissue to a greater extent than the hard socket. Furthermore, the movable range of the elbow joint widened as the shape of the socket itself changed

Comprehensive identification of sphingolipid species by in silico retention time and tandem mass spectral library

Additional file 1. Figure S1 The fragment assignments of 12 sphingolipid classes. The annotations were combinatorially performed by hydrogen rearrangement rules in combination with substantial manual curation. The original spectra were obtained from LC/MS data of some biological samples including human cells, mouse tissues, and plant species
