The technology is based on microbial fuel cells (MFCs), which use microorganisms as catalysts to convert chemical energy to electrical energy. The paper’s authors, including Bruce Logan of Pennsylvania State University and Xiaoxin Cao of Tsinghua University (China), are among the small group of researchers worldwide trying to improve MFCs—or bioelectrochemical systems, as they are beginning to ...

BACKGROUND The aim of this study was to test seven previously published image-input methods in state-of-the-art high resolution PET brain images. Images were obtained with a High Resolution Research Tomograph plus a resolution-recovery reconstruction algorithm using two different radioligands with different radiometabolite fractions. Three of the methods required arterial blood samples to scale...
A valid quantitative imaging method for the measurement of amyloid deposition in humans could improve Alzheimer's disease (AD) diagnosis and antiamyloid therapy assessment. Our group developed Pittsburgh Compound-B (PIB), an amyloid-binding radiotracer, for positron emission tomography (PET). The current study was aimed to further validate PIB PET through quantitative imaging (arterial input) a...
The widely used Logan plot in radioligand receptor dynamic PET studies produces marked noise-induced negative biases in the estimates of total distribution volume (DV(T)) and binding potential (BP). To avoid the inconsistencies in the estimates from the Logan plot, a new graphical analysis method was proposed and characterized in this study. The new plot with plasma input and with reference tis...
شته غلات sitobion avenae (f.) (hemiptera: aphididae) یکی از آفات مهم گندم و زنبور praon volucre (hymenoptera: braconidae) یکی از پارازیتوئیدهای اصلی این شته در ایران است. در این تحق‍یق، نیازهای گرمایی شته غلات و پارازیتوئید آن در 6 دمای ثابت (10، 15، 20، 25، 5/27 و 30 درجه سلسیوس)، رطوبت نسبی 5±60 درصد و دوره نوری 16 ساعت روشنایی و 8 ساعت تاریکی، روی گندم (رقم پ‍یشتاز) مورد ارزیابی قرار گرفت. ط...
