Symbioses between sponges and algae are abundant in the nutrient-poor waters of tropical reefs, yet very little is known of the nutritional interactions that may promote this abundance. We measured nitrogen flux between the sponge Haliclona cymiformis and its symbiotic partner, the rhodophyte Ceratodictyon spongiosum, and assessed the potential importance of this flux to the symbiosis. While th...

Four cultivars and 21 lines of cotton were evaluated for resistance to ramulose (Colletotrichum gossypii f. sp. cephalosporioides) in a field where the disease is endemic. The seeds of each genotype were planted in 5 x 5 m plots with three replications. The lines CNPA 94101 and ‘CNPA Precoce 2’were used as standard susceptible and resistant references, respectively. The disease incidence (DI) w...

The objectives of this article are to study the sum IS(d) and to find some upper din bounds for Smarandache's function. This sum is proved to satisfy the inequality IS(d) ~ n at most all the composite numbers, Using this inequality, some new din upper bounds for Smarandache's function are found. These bounds improve the well-known inequality Sen) ~ n.

Toplumun temel kurumlarından bir tanesi de dindir. Din, insanlık tarihi ile başlamış ve yaşıt evrensel olgudur. Tarihin her döneminde toplumda var olmuş, günümüzde varlığını en canlı şekilde hissettiren önemli hassas kurumdur. Antropoloji bilimi tarih boyunca bireysel olarak inanmayan kişiler olmakla beraber top yekûn dinsiz topluma rastlanmadığını haber vermektedir. İnsanların huzur mutluluğun...

We developed a HPLC/MS method for the identification and determination of solanine in plants. This method was applied for samples of Solanum dulcamara (from Iaşi and Vânători Neamţ areas in Romania) and Physalis alkekengi (from Bucium and Breazu, Iaşi, Romania) during August-September 2009. Isolation of solanine was performed by extraction with a mixture consisting of water/methanol/acetic acid...

Let 0= U0,n ≤ U1,n ≤ ··· ≤ Un−1,n ≤ Un,n = 1 be an ordered sample from uniform [0,1] distribution, and Din = Ui,n −Ui−1,n, i = 1,2, . . . ,n; n = 1,2, . . . , be their spacings, and let f1n, . . . , fnn be a set of measurable functions. In this paper, the probabilities of the moderate and Cramer-type large deviation theorems for statistics Rn(D)= f1n(nD1n) + ···+ fnn(nDnn) are proved. Applicati...
