ویژگی‌های زیستی به‌ویژه رفتار تخمریزی زنبورهای پارازیتویید یکی از مهم‌ترین عوامل تعیین‌کننده کارایی آنها در مدیریت جمعیت آفت میزبان می‌باشد. این مطالعه الگوی وابسته به سن، نرخ پارازیتیسم، درصد تفریخ و نسبت جنسی زنبور Trichogramma brassicae روی Ephestia kuehniella شرایط آزمایشگاهی (1±25 درجه سلسیوس، رطوبت نسبی %5±70 دوره نوری 16: 8 ساعت (روشنایی: تاریکی)) بررسی شد. نتایج نشان داد T. سنین جوانی (...

The doped perovskite cobaltite La1−xSrxCoO3 LSCO has been advanced as a model system for studying intrinsic magnetic phase separation. We have employed a first-order reversal curve FORC method to probe the amount of irreversible switching in bulk polycrystalline LSCO as a function of Sr doping, field cooling procedure, and temperature. The value of the FORC distribution is used as a measure of ...

[1] The global paleointensity database is restricted by the high failure rate of paleointensity analyses. Excluding thermal alteration, failure is usually caused by the presence of multidomain grains and interactions among grains, two properties that can be identified using first-order reversal curve (FORC) diagrams. We measured FORC diagrams on sister samples of about 200 samples that had been...

[1] Identification of the mineral remains of magnetotactic bacteria (MTB), known as magnetofossils, is of particular interest because their occurrence can be used for environmental and climatic reconstructions. Single‐domain magnetite particles, which are biomineralized in the cell body of MTB, have characteristic properties that can be used to detect their fossil remains. Acquisition of anhyst...

The dynamics near firstand second-order phase transitions in a two-dimensional lattice-gas model are compared using the first-order reversal curve (FORC) method. The FORC diagram of a first-order transition is characterized by a negative region separating two positive regions, reflecting a competition between the time-varying electrochemical potential and the tendency of the system to phase order.
