This study focused on the formability of aluminium alloy（7075-T6） sheets through hydroforming route. Formability of these sheets was tested using a warm forming setup at three diferent temperatures and four diferent die corner radii. Forming limit diagrams（Fld） were generated by measuring the grids of the sheet formed. The results show that the forming limit of AA7075-T6 can be significantly improved when the blank was heated to 140–250℃. it was also observed that as the temperature increases above 140℃, dome height began to decrease. Also the results indicated that both the die corner radius and temperature have a significant efect on the stress-strain curve and warm forming of AA7075-T6 sheets. Thus, with the temperature increased from room temperature（RT） to 140℃, the flow stress decreased and the strain increased, hence, the formability is enhanced. However, further increase in temperature causes decreases the flow stress and strain. Similar changes of the flow curve were seen in die corner radius. Decreasing the die corner radius decreases the flow stress and increase the strain. Moreover, an equation was obtained by establishing correlations between the experimental parameters and their results. in this way, it became possible to make predictions.

kad.is one of the largest scale DHT based on real applications. Measurements on kad.is a good approach for researching DHT. Many different active and passive measurements have been made on those systems, and crawlers are novel approach in active measurement. A crawler begins crawling into the DHT with a basic set of given nodes, sending node searching requests to the nodes in the given set for contact information from more unknown nodes. There are three goals in mind while we design the crawler: finishing crawling the given nodes set as soon as possible; retrieving more nodes information after the crawling; getting result while sending as few network packets as possible. The above goals are correlated with each other. Optimizing one may impact others. This paper proposes a basic DHT crawler framework and discusses possible extension to the framework. After that we exploit the fact that the connectivity in the overlay network is universality, thus we do not need to crawl the whole overlay network space while maintaining the crawling affect.

Background: Rheumatoid arthritis is a chronic autoimmune disease that causes socio-economic, psychological and sexual problems. It imposes limitations on sexual relationships and these issues are still taboo in African society. Objective: Tpan>he objective is to assess the impact of rheumatoid arthritis (RA) on women’s sexuality at the Ignace Deen National Hospital. Patients and Methods: This was an analytic case-control study of 8 months (from April 6, 2020 to December 11, 2020). All patients followed for rheumatoid arthritis diagnosed according to 2010 ACR/EULAR criteria for RA had been included. Results: One hundred and five women (52 RA patients and 53 controls) were collected. The two groups were comparable in terms of demographic characteristics. Sexual dysfunction was found in 69.2% of cases versus 35.8% of controls. Women with RA had poorer sexual functioning in the categories of desire, arousal, lubrication, orgasm, satisfaction, and pain of the FSFI score compared to healthy women (p = 0.01;p = 0.7;p = 0.3;p = 0.8;p = 0.1;and p = 0.3 respectively). Patients were 4 times more likely to have sexual dysfunction than healthy individuals and this result was statistically significant with a p-value less than 0.05. Conclusion:pan style="

The reinforcement of premating barriers due to reduced hybrid fitness in sympatry may cause secondary sexual isolation within a species as a by-product. Consistent with this, in the fly Drosophila subquinaria, females that are sympatric with D. recens mate at very low rates not only with D. recens, but also with conspecific D. subquinaria males from allopatry. Here, we ask if these effects of re- inforcement cascade more broadly to affect sexual isolation with other closely related species. We assay reproductive isolation of these species with D. transversa and find that choosy D. subquinaria females from the region sympatric with D. recens discriminate strongly against male D. transversa, whereas D. subquinaria from the allopatric region do not. This increased sexual isolation cannot be explained by natural selection to avoid mating with this species, as they are allopatric in geographic range and we do not identify any intrinsic postzygotic isolation between D. subquinaria and D. transversa. Variation in epicuticular hydrocarbons, which are used as mating signals in D. subquinaria, follow patterns of premating isolation： D. transversa and allopatric D. subquinaria are most similar to each other and differ from sympatric D. subquinaria, and those of D. recens are distinct from the other two species. We suggest that the secondary effects of reinforcement may cascade to strengthen reproductive isolation with other species that were not a target of selection. These effects may enhance the divergence that occurs in allopatry to help explain why some species are already sexually isolated upon secondary contact.
