Intercropped corn (Zeu mays L.) and soybean [Glycine mux (L.) Merr.] may produce more total yield per hectare than either grown separately, ie., land equivalent ratio (LER) >l. Low N fertility, limited moisture, and weed competition have each been reported to result in high land equivalent ratios. Thus it was hypothesized that intercropping advantages were greater under stress conditions. The o...

Ler is a DNA-binding, oligomerizable protein that regulates pathogenicity islands in enterohemorrhagic and enteropathogenic Escherichia coli strains. Ler counteracts the transcriptional silencing effect of H-NS, another oligomerizable nucleoid-associated protein. We studied the oligomerization of Ler in the absence and presence of DNA by atomic force microscopy. Ler forms compact particles with...

Abstract A field experiment was conducted at the teaching and research farm of Faculty Agronomy Agricultural Sciences University Dschang to investigate effects potato– Mucuna intercropping pattern on agronomic performances potatoes soil physicochemical properties in western highlands Cameroon. The design a randomized complete block with three replications. treatments included pure potato stand ...

In a previous paper, we started an enumeration of the finitely many levels for which a principal congruence manifold can be a link complement in S. In this paper we give a complete enumeration of all the principal congruence link complements in S, together with their levels in the case when the class number of Q( √ −d) is greater than 1.

Many atomic and molecular systems of fundamental interest possess resonance frequencies in the extreme ultraviolet (XUV) where laser technology is limited and radiation sources have traditionally lacked long-term phase coherence. Recent breakthroughs in XUV frequency comb technology have demonstrated spectroscopy with unprecedented resolution at the megahertz level, but even higher resolutions ...

OBJECTIVE Angiotensin-converting enzyme inhibitors (ACEIs) have not been well evaluated in conjunction with lower extremity revascularization (LER). This study evaluated freedom from amputation in patients who underwent either an open (OPEN) or endovascular (ENDO) revascularization with and without utilization of an ACEI. MATERIALS AND METHODS Patients who underwent LER were identified from 2...

Consider a planar Brownian motion run for nite time. The frontier or \outer boundary" of the path is the boundary of the unbounded component of the complement. Burdzy (1989) showed that the frontier has innnite length. We improve this by showing that the Hausdorr dimension of the frontier is strictly greater than 1. (It has been conjectured that the Brownian frontier has dimension 4=3, but this...

Observations of CO molecules in the millimetrer domain at high redshift (larger than 1), have provided interesting informations about star formation efficiency, and its evolution with redshift. Due to the difficulty of the detections, selection effects are important. The detection if often due to gravitational amplification. Objects selected by their (far)infrared flux, are in general associate...

We studied gate line edge roughness (LER) and its effect on electrical characteristics of 50nm bulk MOSFETs. Using simulation, we studied the underlying mechanism of three significant LER effects on the electrical performance of advanced 50 nm gate length bulk devices. First, we found that off-state leakage current is much more sensitive than the on-state drive current to gate LER. Second, we f...

to evaluate the yield and quality of barley (hordeum vulgare)–vetch (vicia desycarpa) intercropping, a series of experiments were conducted at the experimental field of the college of agriculture, university of tehran, in karaj (iran) from 2003 to 2005. the ex-periments were arranged in a randomized complete block with a split plot design and four replications. three levels (0, 45 and 90 kg n h...
