The log-log plot of the cumulative numbers of infected and deceased cases through the progress of the 2009 H1N1 pandemic gave a relation given by the equation logY = klogX – klogN0, where Y is the cumulative number of infected cases, X the cumulative number of deaths, k the coefficient representing the slope of the curve, and N0 the value of X when the curve crosses the X axis (1). The analysis...

Fokus dari penelitian ini adalah karakteristik dimensi utama kapal pukat cincin yang berpangkalan di Pelabuhan Perikanan Pantai (PPP) Belang Minahasa Tenggara. Penelitian bertujuan untuk mengetahui rasio atau perbandingan ukuran (L/B, L/D, dan B/D), hubungan antar-ukuran (L vs B, L D, B D), (L) dengan kapasitas muat (GT) serta daya mesin pendorong (HP). Metode analisis data dilakukan menggunaka...

the purpose of this paper is to study the higher order asymptotic distributions of the eigenvalues associated with a class of sturm-liouville problem with equation of the form w??=(?2f(x)?r(x)) (1), on [a,b, where ? is a real parameter and f(x) is a real valued function in c2(a,b which has a single zero (so called turning point) at point 0x=x and r(x) is a continuously differentiable function. ...

The objective of this study was to evaluate and compare the erosion rates generated by two types hand tools for small-scale tillage on a hillslope, using experimental tests Universal Soil Loss Equation (USLE). evaluated were conventional hoe redesigned furrowing hoe. work conducted in 145 m2 plot with an average slope 45% Colombia. Three treatments evaluated: a) Zero no herbicide (control); b) ...

Let the random variables {Bj} N j=1 represent the states of theN cAMP receptors on the cell surface; Bj = 1 if the receptor is bound to a molecule of cAMP, otherwise Bj = 0. Each receptor is taken to lie on the surface of a sphere of radius R = 7.5μm, with displacement from the center of the cell in a direction given by a unit vector ~x ∈ S. We set the center of the sphere to be the origin of o...

background: the refolding of proteins from inclusion bodies is affected by several factors, including solubilization of inclusion bodies by denaturants, removal of the denaturant, and assistance of refolding by small molecule additives. objectives: the purpose of this study was optimization of recombinant human interferon-b purification in order to achieve higher efficiency, yield, and a produc...

Peak velocity and peak acceleration of disaccommodation step responses remain invariant of response magnitude for a constant starting position and they increase linearly with proximity of starting position. This suggests that disaccommodation response is initiated towards an initial (default) destination and is switched mid-flight to attain the desired final destination. The dioptric location o...

The problem associated with use of statistical methods for determining a best linear relationship of the form Y = AX +B have been examined for a condition quite prevalent with experimental research, i.e., when the values of both variables are subject to essentially unknown errors. Under this condition standard least-squares regression analysis underestimates the value of the slope A. A very sim...
