This study identified the meteorological parameters that influence PM2.5 concentrations in Greater Cincinnati area by employing principal components analysis and multi-variable regression. Meteorological data were collected over several years to derive statistical relationships about seasonal variability of quantify their on PM2.5. We studied effect seasons k-means clustering. The results show ...

Due to climate change, floods have been more frequent in recent years. Estimating the flood discharge as a result of frequency analysis is very substantial make necessary preparations for possible floods. Data covering 36 years were collected from different stream gauging stations (SGS No: D17A016 and EIEI 1731) Eastern Mediterranean Basin. With these data, values computed return periods 2, 5, ...

Analysis of social interactions has recently become an important area of economic research, and the focus of researchers in this area has increasingly shifted toward dynamic models. In one recent contribution, Brueckner and Smirnov (2006) analyze the evolution of population attributes in an exceedingly simple model where an agent’s attributes at time t are equal to the average attribute value a...

Introduction: Raising antibiotic resistance has led the human community to more frequent application of herbal medicines. The tomato fruit, scientifically called Lycopersicon esculentum mill, is an important source of vitamins, minerals, and antioxidants, all with beneficial effects on human health. The present study aimed to evaluate the antibacterial effects of tomato aqueous extract on four ...

We study the problem of distinguishing between two distributions on a metric space; i.e., given metric measure spaces (X, d, μ1) and (X, d, μ2), we are interested in the problem of determining from finite data whether or not μ1 is μ2. The key is to use pairwise distances between observations and, employing a reconstruction theorem of Gromov, we can perform such a test using a two sample Kolmogo...

INTRODUCTION Proper maintenance policy can play a vital role for effective investigation of product reliability. Every engineered object such as product, plant or infrastructure needs preventive and corrective maintenance. CASE DESCRIPTION In this paper we look at a real case study. It deals with the maintenance of hydraulic pumps used in excavators by a mining company. We obtain the data tha...

Energy-dependent solar neutrino flux reduction caused by the Mikheyev– Smirnov–Wolfenstein (MSW) effect is applied to the Exact Parity Model. Several scenarios are possible, depending on the region of parameter space chosen. The interplay between intergenerational MSW transitions and vacuum “intragenerational” ordinary–mirror neutrino oscillations is discussed. Expectations for the ratio of cha...

Xiangdong Shi and George M. Fuller Department of Physics, University of California, San Diego, La Jolla, California 92093-0319 (December 16, 1998) We propose a new and unique dark matter candidate: ∼ 100 eV to ∼ 10 keV sterile neutrinos produced via lepton number-driven resonant MSW (Mikheyev-Smirnov-Wolfenstein) conversion of active neutrinos. The requisite lepton number asymmetries in any of ...
