The title compound, C21H17N3O3, is a new polymorph of an already published structure [Shashidhar et al. (2006 ▶). Acta Cryst. E62, o4473-o4475]. The previously reported structure crystallizes in the monoclinic space group C2/c, whereas the structure reported here is in the tetra-gonal space group I41/a. The bond lengths and angles are similar in both structures. The mol-ecule adopts an extended...
The diversity of a collection of 21 bradyrhizobial isolates from Lima bean (Phaseolus lunatus L.) was assayed by molecular methods. Moderately high to high genetic diversity was revealed by multilocus enzyme electrophoresis (MLEE) analysis of seven enzyme loci and genomic fingerprints with ERIC and BOX primers. Two groups with differences in growth rate were found among the isolates and their d...
We review the status of FEL source activity of the ongoing SPARC FEL experiment, developed within the framework of a collaboration among ENEA, CNR, INFN, INFM, Sincrotrone Trieste and University of Rome Tor Vergata. The project is aimed at realising a SASE-FEL source, operating in the visible (around 500 nm), with an extended range of tunability down to the VUV (100 nm) by the use of the mechan...
Background: Exercise and consumption of green tea affect the aging process. However, the effect of exercise training combined with green tea extract on leukocyte telomere length, quality of life (QoL) and body composition in aging has so far been unclear and inconsistent. Objective: The aim of the present study was to determine the effectiveness of aerobic training intervention and green tea e...
Yong-Bin Kim* Tom Chen** *Microelectronics Division Samsung Electronics Co. San Jose, CA, USA **Department of Electrical Engineering Colorado State Univ. Fort Collins, CO 80523, USA Abstract This paper describes a CMOS variable delay line Delay Locked Loop(DLL) circuit speci cally designed for reducing clock skew on DRAM/Logic merged integrated circuit using 0.6 m CMOS process. A phase detector...
Global tree cover percentage is an important parameter used to understand the global environment. However, the available global percent tree cover products are few, and efforts to validate these maps have been limited. Therefore, producing a new broad-scale percent tree cover dataset is valuable. Our study was undertaken to map tree cover percentage, on a global scale, with better accuracy than...
In this paper, we present: 1) design of a single-rail energy-efficient 64-b Han–Carlson ALU, operating at 482 ps in 1.5 V, 0.18m bulk CMOS; 2) direct port of this ALU to 0.18m partially depleted SOI process; 3) SOI-optimal redesign of the ALU using a novel deep-stack quaternary-tree architecture; 4) margining for max-delay pushout due to reverse body bias in SOI designs; and 5) performance scal...
