In this investigation, the interaction of C20 and Si2H2 molecules was explored in the M06-2X/6-311++G(d,p)level of theory in gas solution phases. The obtained interaction energy values with standard method werecorrected by basis set superposition error (BSSE) during the geometry optimization for all molecules atthe same level of theory. Also, the bonding interaction between th...

UNLABELLED The aim of this study is to make a correlation of the clinical and radiographic results after performing two different surgical procedures for correction of hallux valgus deformity. MATERIAL AND METHODS The study included 70 patients having hallux valgus deformity of the foot, and they were divided into two groups. The first group (Group 1) was composed of 35 patients who were trea...

We consider the phenomenon of collapse in the critical Keller–Segel equation (KS) which models chemotactic aggregation of micro-organisms underlying many social activities, e.g. fruiting body development and biofilm formation. Also KS describes the collapse of a gas of self-gravitating Brownian particles. We find the fluctuation spectrum around the collapsing family of steady states for these e...

Staff selection has been historically done intuitively by the person in charge, looking mainly to technical and professional aspects. In the past years there has been an important trend to assist the selection process by a psychologist that evaluates capability aspects and skills like creativity, motivation, leadership and intelligence. These aspects, however, do not guarantee that the applican...

Karies gigi adalah masalah utama bagi kesehatan dan rongga mulut di Indonesia, salah satu penyebabnya mikroorganisme, yaitu Streptococcus mutans. Oleh karena itu diperlukan agen antibakteri untuk mencegah perkembangannya. Belakangan ini beberapa bahan alam telah dikaji terbukti memiliki aktifitas antibakteri, diantaranya tanaman sereh (Cymbopogon citratus) sirih hijau (Piper betle L.). Peneliti...

In two space dimensions, the parabolic-parabolic Keller-Segel system shares many properties with the parabolic-elliptic Keller-Segel system. In particular, solutions globally exist in both cases as long as their mass is less than a critical threshold M(c). However, this threshold is not as clear in the parabolic-parabolic case as it is in the parabolic-elliptic case, in which solutions with mas...
