OBJECTIVE To report recent data on the distribution of human and canine visceral leishmaniasis (VL) in Venezuela, and to highlight problems associated with effective control measures. METHODS We report the number of cases, incidence rate, age and sex distribution, and mortality rates for human VL (HVL) for the period of 1995 through 2000, based on National Registry of Leishmaniasis data. We c...

Abstract Epoxy resins with varying amounts of MoO 3 were theoretically investigated for their radiation shielding ability at low energies (between 0.0395 and 0.344 MeV). The quantity varied from 0 to 30%, relevant parameters obtained analyzed Phy-X software. half value layer (HVL) the demonstrated that increasing content improved space-efficiency prepared samples all tested energies, leading Mo...

Abstract In São Luís, Maranhão, northeastern Brazil, the notification of visceral leishmaniasis (VL) cases intensified in 1982, showing endemic and epidemic patterns. this city, Center for Zoonoses Control (CZC) was an organization charge control prevention disease. However, technical political reasons have led to a significant decline periodicity its activities. Therefore, study we evaluated e...

Abstract The radiation attenuation characteristics of WO 3 -Li 2 O-ZnO-P O 5 glasses have been examined using Phy-X software. linear coefficient is correspondingly increased with the inclusion , which indicates existence a reducing tendency in photon transmission correlating an increment content glasses. When density increased, there considerable reduction half-value layer (HVL), most noticeabl...

BACKGROUND Engaging people who drink alcohol or inject drugs in HIV care can be challenging, particularly in Eastern Europe. Healthcare facilities in Russia are organized by specialty; therefore linking patients from addiction care to HIV hospitals has been difficult. The HIV care cascade outlines stages of HIV care (e.g., linkage to care, prescribed antiretroviral therapy [ART], and achieving ...


 Background:Quality control of conventional x-ray tube ensures that the patient integral radiation dose is minimized and image quality improved, by controlling beam to reduce scatter radiation.
 Objective:To assess tubes for half value layer (HVL), field light congruence using known standard.
 Methodology:The HVLs were measured calibrated, non-invasive, digital multifunctional d...

We use ultrasound to explore the lingual articulation of /hVd/ and /hVl/ rhymes from an Australian English speaker, focusing on the coarticulatory interactions between the VC rhyme components. Results reveal vowel height as a major factor conditioning lateral undershoot. We also find that back vowel tongue contours overlap extensively with the coda lateral providing a conditioning environment f...

Background: This study investigated the γ-rays shielding properties of some building materials in Sudan has been investigated. Materials and Methods: Photons attenuation coefficients and half value layer (HVL) were experimented using Cs-137 and Co-60 sources.  The measurements were performed to gauge the intensity of radiation when performed unshielded, the specific thickness of selected sample...
