Hutan mangrove merupakan ekosistem pesisir yang memiliki peran penting sebagai habitat, tempat mencari makan, pemijahan, dan pembesaran berbagai jenis organisme akuatik, seperti ikan, moluska, crustacea, termasuk kepiting. Kepiting bakau (Scylla sp.) ditemukan melimpah di spesies kunci. Kelimpahan kepiting dipengaruhi oleh kondisi lingkungan. Tujuan penelitian ini untuk mengetahui kelimpahan di...

Wide-field imaging is key to many of the science goals of the EVLA in both Phase I and Phase II. Optimization of wide-field imaging algorithms is therefore vital. In this memo, we consider the existing algorithms for dealing with non-coplanar baselines and propose a new algorithm with markedly superior performance. At roughly equivalent levels of accuracy, this new algorithm, which we call “w-p...

When mouse embryonic fibroblasts in suspension contact a matrix-coated surface, they rapidly adhere and spread. Using total internal reflection fluorescence microscopy of dye-loaded fibroblasts to quantify cell-substrate contact, we found that increasing the surface matrix density resulted in faster spreading initiation whereas lamellipodial dynamics during spreading were unaltered. After sprea...

Let G be a simple graph possessing n vertices and m edges. Let di be the degree of the i-th vertex of G , i = 1, . . . , n . The first Zagreb index M1 is the sum of d 2 i over all vertices of G . The second Zagreb index M2 is the sum di dj over pairs of adjacent vertices of G . In this paper we search for graph for which M1/n = M2/m , and show how numerous such graphs can be constructed. In add...

The capture or scattering of an initially straight infinite test cosmic string by a Kerr-Newman black hole, or by any other small source of an electrovac gravitational field, is analyzed analytically when the string moves with initial velocity v0 and large impact parameter z0 = b M so that the string stays very nearly straight (except during the final capture process, if that occurs, or except ...

Phenomena of neutrino oscillations are discussed on the basis of two-loop radiative neutrino mechanism. Neutrino mixings are experimentally suggested to be maximal in both atmospheric and solar neutrino oscillations. By using Le −Lμ −Lτ (≡ L )-conservation, which, however, only ensures the maximal solar neutrino mixing, we find that two-loop radiative mechanism dynamically generates the maximal...

because plant density is often measured by using plots and also in most cases are done by the method of estimation and counting the individuals, so one of the important cases that we have to decide on is the size and shape of plot. in this research, the density of astragalus verus that it's one of the dominate species in the area and has separate and recognizable individuals plant from eac...
