A field experiment to compare forage yield and quality of eight sorghum cultivars/genotypes namely JS-263, JS88, Hegari, F-9601, F-9603, F9706, F-9806 and F-9809 was conducted at the Agronomic Research Area, University of Agriculture, Faisalabad during the year 2008. Significant differences were observed among the genotypes for forage yield and quality. The variety F-9603 produced significantly...

We studied tree height in stands of high-Andean Polylepis forests in two cordilleras near Cuzco (Peru) with respect to variations in human impact and climatic conditions, and compared air and soil temperatures between qualitatively defined dry and humid slopes. We studied 46 forest plots of 100 m(2) of five Polylepis species at 3560-4680 m. We measured diameter at breast height (dbh) and tree h...

The identification of over-represented but imperfectly conserved motifs in genomic DNA is a problem with important biological applications, such as the discovery of regulatory elements that determine the timing, location, and level of gene transcription. Experimental techniques such as ChIP-chip and geneexpression microarrays can identify sets of genomic regions that are likely to be enriched f...

We propose a natural generalization of Regularized Maximum Entropy Density Estimation (maxent) to handle input data with unknown values. While standard approaches to handling missing data usually involve estimating the actual unknown values, then using the estimated, complete data as input, our method avoids the two-step process and handles unknown values directly in the maximum entropy formula...

Let A be a sequence of n ordered pairs of real numbers (ai, li) (i = 1, . . . , n) with li > 0, and L and U be two positive real numbers with 0 < L U . A segment, denoted by A[i, j], 1 i j n, of A is a consecutive subsequence of A between the indices i and j (i and j included). The length l[i, j], sum s[i, j] and density d[i, j] of a segment A[i, j] are l[i, j] = ∑j t=i lt, s[i, j] = ∑j t=i at ...

Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40...

Dome C and A of the Antarctic plateau is considered to be the best astronomical site on the earth because of extremely cold, dry weather, low wind speed and atmospheric turbulence overhead. CSTAR (Chinese Small Telescope ARray), which is composed of four small telescopes with 100mm clear aperture, has been accomplished in August and shipped to Antarctic at November 2007. Then, from the Zhongsha...

chickpea (cicer arietinum l.) is a dry pulse crop commonly used from old time. the chickpea yield is lower as compared to maximum potentials of the cultivars. the gap could mainly be attributed to the weed competition in addition to other production constraints. although chickpeas are traditionally grown on residual soil moisture, weeds competition pose major problem in many situations. in orde...
