Male infertility may occur due to different causes, therefore , different therapeutic approaches have been applied in order to improve the ability of men to get children . Semen analysis is used to determine the fertility potential in males, but the occurrence of pregnancy is the evidence of sperm ability for fertilization. Although male fertility

The present study examines the phylogenetic relationships among Tor douronensis, T. tambra, T. tambroides of the genus Tor and Neolissochilus stracheyi representing the genus Neolissochilus, by using the partial sequencing of the mitochondrial DNA cytochrome c oxidase I (COD gene. Samples were collected from various rivers throughout Sarawak, Sabah

The 2006 Israel's military attack on Lebanon raises numerous issues concerning 'jus ad bellum' and 'jus in bello' rules of international law relating to international armed conflict. Jus ad bellum or the law relating to the initiation of war is now regulated by the Charter of the United Nation (UN). The UN Charter prohibits the

Universal Newborn Hearing Screening (UNHS) is an important tool for detecting hearing impairment in newborns, but it is often hindered by unacceptably long test times. This paper will describe a preliminary data set obtained from 100 newborns using a new form of automated auditory brainstem response (AABR): a non-linear maximum length sequence (MLS

This paper presents an approach to optimize the surface finish in end milling titanium-alloy of Ti-6AI-4V using uncoated WC-Co and PCD inserts under dry conditions. Response surface methodology is utilized to develop an efficient mathematical model for surface roughness in terms of cutting speed, feed and axial depth of cut. For this purpose, a num

In this Letter, we apply the homotopy-perturbation method (HPM) to obtain approximate analytical solutions of the time-dependent Emden– Fowler type equations. We also present a reliable new algorithm based on HPM to overcome the difficulty of the singular point at x = 0. The analysis is accompanied by some linear and nonlinear time-dependent sing

In this Letter, the homotopy-perturbation method (HPM) is employed to derive approximate series solutions of nonlinear population dynamics models. The nonlinear models considered are the multispecies Lotka–Volterra equations. The accuracy of this method is examined by comparison with the available exact and the fourth-order Runge–Kutta method (

In this Letter, solutions of a class of singular initial value problems (IVPs) in the second-order ordinary differential equations (ODEs) by homotopy-perturbation method (HPM) are presented. HPM yields solutions in convergent series forms with easily computable terms, and in some cases, yields exact solutions in one iteration. Comparisons with the

This paper presents an automatic sign language translator, which is able to translate Malaysian sign language using pattern-matching algorithm. The sign language translator is a vision-based system where the image of the sign is captured by a camera, processed and translated into English by the computer. This sign language translator is able to rec

This note examines the empirical validity of the monetary model of exchange rate determination for The Philippines via cointegration and vector error-correction model. It is found that the monetary model is a valid framework for the long-run exchange rate between Philippines peso-US Dollar exchange rate. However, the typical linear restrictions of
