We compute the minimum and maximum of the probability of k or more successes in n exchangeable Bernoulli trials as a function of the correlation coefficients. This probability finds wide application in reliability and decision theory. Since the probability is linear in the coefficients, finding the minimum andmaximum requires solving linear programming problems. We show that the maximum can be ...

Abstract This study aims to determine the effect of young coconut waste biochar and goat manure application on chemical properties entisol. The Biochar Research Station, Universitas Syiah Kuala, conducted research. used a factorial randomized block design consisting two factors. first factor was dose (0, 5, 10 t ha -1 ), second 10, 15 ). Parameters observed in this were soil analysis entisol (p...

The amphipathic alpha helix is an often-encountered secondary structural motif in biologically active peptides and proteins. An amphipathic helix is defined as an alpha helix with opposing polar and nonpolar faces oriented along the long axis of the helix. In a recent review article we grouped amphipathic helixes into seven distinct classes (A, H, L, G, K, C, and M) based upon a detailed analys...

Ferritin concentrates iron as a hydrous ferric oxide in a protein cavity (8 nm in diameter) by using eight pores along the threefold symmetry axes of the octahedral supramolecular structure. The role of ligand exchange in the entry of Fe(II) hexahydrate into ferritin protein has been studied with [Cr(TREN)(H2O)(OH)] [TREN N(CH2CH2NH2)3], a model for Fe(H2O)6 with only two exchangeable ligands. ...

The growth rate of Sarcoma 180 and of a mammary adenocarcinoma in potassium deficient mice did not significantly differ from that in pair-fed control mice. The po tassium concentration of these tumors in potassium-deficient mice was the same as in the control mice, although the potassium concentration of muscle and plasma was only half of that in the controls. The in vivo equilibration of K@ in...

Potassium (K) is essential for plant growth and vital soil health. However, despite high crop demand, K fertilization continues to be ignored or severely inadequate in Indian agriculture. Over time, this could lead severe depletion of reserve, irreversibly alter K-bearing minerals, adversely affect fertility productivity. Hence, we should comprehensively assess the alarming situation mining Ind...

Efforts have been made in this study to stabilize the sewage sludge mixed with sugarcane trash in four different proportions: 20% (T(1)); 40% (T(2)); 60% (T(3)) and 80% (T(4)), under laboratory conditions using epigeic earthworm (Oligochaeta) Eisenia fetida. The composting potential of worm was also evaluated in 100% sewage sludge treatment (T(5)). The changes in chemical properties of substrat...

ABSTRACT The use of high doses vinasse in sugarcane crop can cause modifications the chemical characteristics soil. aim this study was to evaluate effect application on an Ultisol cultivated with for 210 days. treatments used were equivalent 0 (D0), 150 (D150), 300 (D300), 600 (D600) and 1200 (D1200) m3 ha-1 plus a control treatment mineral fertilization. experimental design completely randomiz...

BACKGROUND Hypervolemic hypernatremia is caused by an increase in total exchangeable Na(+) and K(+) in excess of an increment in total body H(2)O (TBW). Unlike patients with hypovolemic or euvolemic hypernatremia, treatment needs to be targeted at correcting not only the elevated plasma Na(+) concentration, but also there is an additional requirement to achieve negative H(2)O balance to correct...
