Single-edged notched tension （SENT） specimen is used to study the fatigue crack growth rate （FCGR） behavior of AISI 50100 steel using MTS 810. Calibration tests are run to get plots of crack mouth opening displacement （CMOD） vs. load and CMOD vs. crack length-to-width ratio with the known crack lengths. Numerical simulation is also done to try to establish a relation between crack length and CMOD. FCGR of welded and un-welded specimens are plotted against stress intensity factor range to show the effect of welding on fatigue crack growth rate of AISI 50100 steel. The experimentally obtained CMOD values are compared with values obtained by numerical simulation using ABAQUS/StandardTM software package. Results show that numerical values are in good agreement with experimental data for small crack lengths and lower values of applied load,

Objective:To test the effect of voltage-gated sodium channels (VGSCs) blockers on the motility and viability of human spermin-vitro and to evaluate the tested compounds as potential contact ***: Sperm samples were obtained from healthy non-smoking volunteers of age 25-30 years who had not taken any drug 3 months before and during the course of the study. The effect of VGSCs blockers evaluated from two pharmacological classes including antiarrhythmic (amiodarone, procainamide and disopyramide) and antiepileptic (carbamazepine, oxcarbazepine, phenytoin, and lamotrigine) drugs. They were tested on thein-vitro motility and viability of human sperm using Computer Assisted Semen ***:All tested drugs except oxcarbazepine showed dose dependent inhibition of total motility with significant reduction (P<0.05) at the maximum concentration of 200 μM when compared with the control. The concentrations of drugs that reduced total sperm motility to 50% of control (half maximal inhibitory concentration) were 2.76, 14.16 and 20.29 μM for phenytoin, lamotrigine and carbamazepine, respectively;and 2.53, 5.32 and 0.37 μM for amiodarone, procainamide and disopyramide, respectively. The anti-motility effects were reversible to various degrees. There was statistically insignificant difference in the inhibition of sperm viability among amiodarone, procainamide and disopyramide. Phenytoin demonstrated the most potent spermicidal ***:VGSCs blockers have significant adverse effects onin-vitro motility of human spermatozoa. Soin-vivo studies are required to determine their potential toxicological effects on human semen quality, which is an important factor regarding fertility. Moreover, these drugs have the potential to be developed into contact spermicidal.

A series of low band gap terpolymers based on 4,8-bis（5-（2-ethylhexyl）thiophen-2-yl）benzo[l,2-b：4,5- b＇]dithiophene （BDTr） and diketopyrrolopyrrole （DPP） with varied solubilizing groups （i.e., tert- butoxycarbonyl, t-Boc and 2-octyldodecyl） are developed as electron donors for bulk heterojunction （BHJ） polymer solar cells （PSCs）. The results reveal that the one with 50% t-Boc concentration （P3） performs better than the other terpolymers used in this study in conventional PSC devices with a power conversion efficiency of 2.92%.
