acute myeloid leukemia (aml) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (mrds) which are resistant to current chemotherapeutic regimens and mediate disease relapse. current therapeutic vaccine strategies have d...

This paper shows the design and control methods of the bidirectional DC-DC converter to generate the proper DC-link voltage of a PMSM drive. Conventionally, because the controllable power of the PWM based voltage source inverter is limited by its DC-link voltage, the DC-DC converter is used for boosted DC-link voltage if the inverter source cannot generate enough operating voltage for the PMSM ...

با توجه به اهمیت حذف یون استرانسیم موجود در پساب‌­های هسته­ای، کار حاضر ضمن سنتز لیگاندهای هیدروکسی بنزآلدهید پروپیل تری اتوکسی سیلان (Si-HL3(EtO)) و پیریدیل متیلیدین (Si-L3(EtO)) بررسی خصوصیات نانو ذرات سیلیکای اصلاح ­شده این لیگاندها ­عنوان جاذب جامد از محلول آبی پرداخته شد پارامترهایی مانند pH، زمان، جرم جاذب، دما یون‌­های مزاحم مورد آزمایش قرار گرفت. رفتار جذبی جاذ­ب‌­ها نشان داد سطح توانای...

This paper deals with a comprehensive survey on the topic of AC/DC & DC/DC converters for DC Motor Drives. A substantial number of different AC/DC and DC/DC topologies appropriate for DC motor drives are presented. This critical literature review brings out merits, demerits, and limitations besides giving the basic operating principles of various topologies. Keywords—controlled-rectifiers, chop...

in this paper, a dc-dc resonant converter with high voltage gain and small size is studied. to reduce the size and weight of this converter, the operating frequency should be as high as possible. in this research, the frequency changes from 120 to 200 khz. due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. resonant converters are su...
