In this paper, we have proposed a new iterative method for finding the solution of ordinary differential equations of the first order. In this method we have extended the idea of variational iteration method by changing the general Lagrange multiplier which is defined in the context of the variational iteration method.This causes the convergent rate of the method increased compared with the var...

Genetic evaluation of dairy animals requires rather large datasets, possibly larger than what is feasible to observe directly through chemical analyses for milk composition and quality traits because they are costly and time consuming. An alternative and more convenient method – use of infrared (IR) spectra – has been proposed (Goulden, 1964). Fourier transformed Infrared (FTIR) spectrometry is...

This paper presents a wireless sensor network (WSN) access control algorithm designed to minimize WSN node energy consumption. Based on slotted ALOHA protocol, this algorithm incorporates the power control of physical layer, the transmitting probability of medium access control (MAC) layer, and the automatic repeat request (ARQ) of link layer. In this algorithm, a cross-layer optimization is pr...

Aims Root canal treatment is a procedure that requires, beyond the realm of technique, knowledge of the internal anatomy of the root canal, specifically the anatomical apex. Almost all methodologies studied thus far are destructive, laborious, and time-consuming and allow for only one-dimensional measurements. In the present study, we used micro-CT technology to evaluate the anatomical structur...

ABSTRACT Geometridae is one of the most diverse Lepidoptera families; however, little information about species found, even regarding their distribution and basic biology, which are in general restricted to type locality. Lists host plants not found for Semiarid region Northeast Brazil. The present note reports occurrence caterpillars Numia terebintharia Guenée consuming leaves evergreen trees ...

cryptosporidiosis is a gastroenteric disease caused by the protozoan parasite cryptosporidium parvum. water–borne transmission of this organism has become more prevalent in recent years. current method for detection of c. parvum oocysts in water is immunofluoresence assay (ifa). the method is time consuming, laborious and particularly not–specific. it cannot determine the infectivity of detecte...
