A power divider (PD)/ power combiner (PC) with high quality factor and enhanced output ports isolation using substrate integrated waveguide (SIW) technology is proposed. An SIW cavity is designed to provide a high quality factor filtering response and an SMD resistor is attached between two output ports to realize the high isolation. The value of the applied resistor is calculated by using the ...

In this work, dynamic mechanical properties of three high-manganese steels with TRIP/TWIP or fully TWIP characteristics are studied. High strain rate experiments in the range of true strain rates between ~500 and 1800 /s are conducted using a dynamic torsional testing setup. All the three steels show a positive strain rate sensitivity in the intermediate range of strain rates (up to 500 /s). Bu...

although the biology and ecology of the arthropod vectors are different, some factors, such as global warming, the increasing abundance of mosquitoes, the movement of domestic hosts, and the abundance of wild reservoirs, can act as favourable factors for the distribution of infections. the aim of this study was to determine the prevalence of dirofilaria immitis infection in shepherd dogs living...

introduction: a great percentage of aids infections occure in adolescence and youth. since that,studing and finding the most efficient teaching methods in order to improve their information ( knowledge) and attitude also to create o positive one and to creat preventive measures in the young and adolescent,is of great significance and priority. materials and methods: 7 school were picked randomy...

background: hemodialysis is a process of removing waste and excess fluid from blood when kidneys cannot function efficiently. it often involves diverting blood to the filter of the dialysis machin to be cleared of toxic substances. fouling of pores in dialysis membrane caused by adhesion of plasma protein and other toxins will reduce the efficacy of the filtre. objective: in this study, the inf...

the original biophysical profile is time consuming and costly. this study was performed to compare diagnostic value of the original fetal biophysical profile to the modified biophysical profile. patients were selected from high risk pregnancies referred for fetal assessment and were randomly assigned to two groups. the measures of outcomes were perinatal mortality, cesarean section for abnormal...

the purpose of research was analyzing attitude of agricultural high school educators in khouzestan province, iran regarding sustainable agriculture. the method of research was correlative descriptive. all agricultural high school educators in khouzestan province (n=55) were selected for participation in the study. a questionnaire was developed to gather information regarding attitude of educato...

background: to compare the effectiveness of basnef and classic educational models to improve the assertion skill level of high school boy students. methods: the 60 high school male students from shiraz city, fars province iran, were participated in this study. they were randomly divided in two groups (groups a and b). the group a attended in designed educational planning based on basnef model a...

in this study we produced and purified a high titer of specific and high affin¬ity fab fragments of anti-digoxin antibody. immunization of rabbits with a conju¬gate of the cardiac glycoside digoxin, coupled by a periodate oxidation method to the amino group of lysine in bovine serum albumin resulted in the production of this type of high titer digoxin-specific antibodies with exceptionally high...

objective(s):osteoarthritis (oa) is globally one of the most common diseases from the middle age onwards. cartilage is an avascular tissue therefore it cannot be repaired in the body. conservative treatments have failed as a good remedy and cell therapy as a decisive cure is needed. one of the best and easily accessible cell sources for this purpose is adipose-derived stem cells which can be di...
