The purpose of this experiment was to determine the influence of the ovarian status on the initiation day of superovulation (d 0) on superovulatory responses in terms of the number of large follicles (≥7mm) at estrus (d 4) and CL 7 days after estrus (d 11). Ultrasonography was performed on d 0, 4 and 11of the experiment. Animals conventionally superovulated (400 mg Folltropin-V) between d 8 to 12 of the estrous cycles and 102 superovulation cycles were considered in the present experiment. Data were analyzed using GLM procedure of the SAS. In these cases, the number of follicles was determined in each of the 2 studied classes (SF, 4 to 6 mm; and LF, ≥7mm) on d 0. Subsequently, each of these classes was divided into two subgroups (Low, High) based on the number of follicles observed on d 0 (Table 1). The number of LF at estrus in each of the 2 studied classes (Low vs. High) were (13.02±1.02 vs. 19.7±1.69, p<0.01; and 16.23±1.59 vs. 14.75±1.48, p>0.1) and the number of CL on d 11 were (9.75±0.57 vs. 12.75±0.98, p<0.01; 10.91±0.8 vs. 10.85±0.65, p>0.1). Therefore, the ovarian status on d 0 in terms of the number of SF affected the number of LF (d 4) and CL (d 11). In addition, the number of superovulatory cycles with low number of SF was 2 times more than the ones with a high number of SF on d 0; also 49 out of 102 superovulatory cycles had at least 2 LF on the initiation day of superovulation (Table 1). These results suggested that follicular puncture 1–2 days before a conventional superovulation treatment may increase the superovulatory responses.

The objective of this experiment was to determine the influence of the ovarian status on the initiation day of superovulation (day 14) on superovulatory response in terms of the number of ovulatory follicles (F, ≥4mm) at estrus (day 16). Estrous cycles of 50 Shall Iranian ewes were synchronized by CIDR. The day of CIDR insertion was considered as the starting point of the experiment (day 0). At the time of CIDR removal (day 14), 650 IU of eCG was administered to ewes. Ultrasonography was performed on days 14 and 16. Data were analyzed by means of the GLM procedure of the SAS. In these cases, the number of follicles were determined in each of the three studied classes (<2, 2 to 4, and ≥4 mm) on day 14. Subsequently, each of these classes was divided into two subgroups (Low, High) based on the number of follicles observed on day 14 (Table 1). The number of large follicles at estrus in each of the three studied classes were (3.96±0.28 vs. 4.78±0.26, p<0.05; 4.31±0.35 vs. 4.41±0.24, p>0.05; and 4.50±0.23 vs. 4.07±0.37, p>0.05) respectively. The number of medium and large follicles on day 14 did not affect the superovulatory response. However, the high number of small follicles on the initiation day of superovulation increased the number of ovulatory follicles at estrus. Since, 23 out of 50 ewes had a low number of small follicles on day 14 (Table 1), which may suggest that an injection of FSH 1-2 days before initiation of eCG treatment enhance the superovulatory response.

The numerical model is developed consisting of a 1D flow model and the morphological model to simulate the erosion due to the water overtopping. The step method is applied to solve the water surface on the slope and the finite difference method of the modified Lax Scheme is applied for bed change equation. The Meyer-Peter and Muller formulae is used to determine the bed load transport rate. The model is calibrated and verified based on the data in experiment. It is found that the computed results and experiment data are good agreement.

Distributive Operator

Abstract Singular nouns in the scope of a distributive operator have been shown to be treated as conceptually plural (Patson and Warren, 2010). The source of this conceptual plurality is not fully clear. In particular, it is not known whether the concept of plurality associated with a singular noun originates from distributing over multiple objects or multiple events. In the present experiment, iterative expressions (distribution over events) were contrasted with collective and distributive sentences using a Stroop-like interference technique (Berent, Pinker, Tzelgov, Bibi, and Goldfarb, 2005; Patson and Warren, 2010). A trend in the data suggests that event distributivity does not elicit a plural interpretation of a grammatically singular noun, however the results were not statistically significant. Possible causes of the non-significant results are discussed.

Actual performance of photovoltaic module with solar tracking is presented. Solar radiation can be converted into electrical energy using photovoltaic (PV) modules. Performance of polycristalline silicon PV modules with and without solar tracking are investigated experimentally. The PV module with dimension 698 x 518 x 25 mm has maximum power and voltage is 45 Watt and 18 Volt respectively. Based on the experiment data, it is concluded that the performance of PV module with solar tracking increases in the morning and afternoon compared with that of fixed PV module. It increases about 18 % in the morning from 10:00 to 12:00 and in the afternoon from 13:30 to 14:00 (local time). This study also shows the daily performance characteristic of the two PV modules. Using PV module with solar tracking provides a better performance than fixed PV module.
