background: cockroaches are of vital importance medically and hygienically as they can disperse human patho­genic agents and are especially responsible for food contamination and spreading of food borne pathogens. in this study, part of mtdna-coi gene of five common pest cockroaches was tested for diagnostic and phylogenetic pur­poses. methods: we have described barcode region of mtdna-coi gene...

Vegetative propagation of potato allows the dissemination of viruses that can cause drastic drops in tuber yield. Potato virus Y (PVY) is one of the most important viruses of potato due to the non-persistent mode of transmission through vector insects. Genetic resistance is the recommended control measure since the chemical control of vector insects is not effective. This study aimed to identif...

Abstract Aims: The study goals were to determine the relationship between faecal indicator bacteria (FIB), the HF183 marker and land use, and the phylogenetic diversity of HF183 marker sequences in a tropical urban watershed. Methods and Results: Total coliforms, Escherichia co...

A system is proposed here for assigning a derived P-marker to a given transformed sentence and obtaining the corresponding base P-marker at the same time. Rules of analytical phrase-structure grammar for such a system have associated with them i~formation pertaining to the transformational histories of their own derivation. When a phrase-structure analysis of the sentence is obtained, the set o...

Introduction Sexual problems and dysfunctions are relatively common experiences which significantly impact on the perceived quality of life; sexual dysfunction has been shown to be associated with anxiety, depression, interpersonal difficulties and overall negative well-being. Recent research has shown that sexual health can be indicative of overall health, for example; erectile dysfunction has...

  Background and Objective: In this study, we explored expression rate, some biomarkers affecting the prognosis of the breast carcinoma, and the relationship between these markers and clinicopathologic features of the disease as well as the relationship between each of these markers through a tissue array technique. Materials and Methods: This study was an observational and cross-sectional st...

One way to perform registration and alignment for machine assembly is with respect to precisely located landmarks, called fiducials. that are located by machine vision means. For applications such as elearonics assembly, where densities are high and tolerances must be low. the precision by which the fiducials are located affects everything aligned relative to them. Because of s~a t ia l sam~l i...
