Prozac Alters Reproductive Performance and Filial Cannibalism in Male Fighting Fish, Betta Splendens
Background: Fluoxetine (ProzacTM) is one of the most popular antidepressant that can be released to aquatic systems via sewage-treatment effluents. It is suspected to provoke substantial effects in the aquatic environment. Methods: In spawning tanks, specimens were exposed to concentrations of 0 and 0.54 µgl-1 fluoxetine from male introduction until the larvae had hatched. Prior to spawning, n...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
The routine chest roentgenogram of pulmonary paragonimiasis heterotremus were evaluated in 93 Thai and Laotian patients. They were 44 males and 49 females; the ages ranged from 12 to 79 years; the history of illness ranged from 4 months to 14 years and the egg output per day was 400 to 300,000. Twelve patients, 12.9% had normal roentgenologic films and 81 patients (87.1%) had abnormalities with...
reproductive performance and life expectancy of the two-spotted spider mite (tssm), tetranychus urticae koch were determined on seven eggplant cultivars (isfahan, dezful, shend-abad, neishabour, bandar-abbas, jahrom and borazjan) at 25 ± 1°c, 60 ± 5% r.h. and a photoperiod of 16:8 (l:d) hours. the results revealed that the tssm gross hatch rate varied from 59% on bandar-abbas to 83% on dezful. ...
the following null hypothesis was proposed: h : there is no significant difference between the use of semantically or communicatively translates scientific texts. to test the null hypothesis, a number of procedures were taken first, two passages were selected form soyrcebooks of food and nutrition industry and gardening deciplines. each, in turn, was following by a number of comprehension quest...
The reproductive biology of Fopius ceratitivorus Wharton, a recently discovered African parasitoid, was studied in quarantine in Hawaii to facilitate its mass production for biological control of the Mediterranean fruit fly, Ceratitis capitata. Mean longevity of host-deprived and ovipositing females was 17.3 ± 0.9 d and 16.2 ± 0.5 d, respectively. Ovarian maturation peaked at 61.6 mature eggs p...
the effect of salicylic acid (sa) on induction of resistance against root-knot nematode (meloidogyne javanica) and the effect of m. javanica to induce biochemical defense responses in tomato (solanum lycopersicum l.) roots at six-leaf stage were investigated. meanwhile, the effect of different concentrations of sa on mortality of second stage juveniles of m. javanica was examined. changes in th...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Mosquito eggs laid within two hours are necessary for transgenic (injection) studies, because mosquito eggs become hard after that period. Thus, in order to have eggs available within this two-hour window, it is important to understand the ovipositional behavior of Anopheles gambiae s.s.. In the present study, the ovipositional behavior of An. gambiae s.s. (Kisumu) was investigated in several d...
