Introduction: Impact crater densities (craters/km2) have allowed successful estimate of planetary surface ages and survival times of topography on modified surfaces [1–3]. Malin et al. recently reported a breakthrough observation: formation rate of small (~20 m) Martian craters [4]. If correct, this will allow even more direct age measurement. History of Technique: The technique was introduced ...

Small-scale domes with circumferential aprons and concentric aureoles in western Arcadia Planitia (34–41°N, 167–179°E) near Tyndall crater were examined using a suite of datasets including CRISM, THEMIS IR, HiRISE, CTX. Previous studies based primarily on photogeologic evidence suggested that these analogous to terrestrial felsic cryptodomes extrusive lava domes. The have also been CRISM visibl...

Background: Radiographic imaging in orthopaedic surgical centers is becoming more common, posing additional risks to the doctors, who become exposed ionising irradiation. As a result, surgeons must have good understanding of radiation hazards. Despite these issues, many specialists do not get basic safety training. A review specialists' understanding, awareness, and routine practices at an acad...

Background: Cross contamination is stated as “Spread of infection between staff members & patients in clinical setting”. throughout training might occur with transfer infectious agents health workers a location. Dental care including dental assistant doctors are at giant risk receiving infection. Aim: To assess the awareness/knowledge practice about cross control among students dentistry St...

Introduction: This study introduces a novel polyvinyl chloride (PVC)/tungsten composites with characterization of their shielding properties by employing different techniques. Methods: The PVC/tungsten composites were produced by employing various weight fractions of tungsten micro-particles including 0, 20, and 40 % wt via melt blending method. In the next st...

Background: The number of interventional cardiology procedures performed has increased rapidly over the past years. While these procedures help physicians avoid using highly complicated invasive methods, it usually leads to high levels of exposure to ionizing radiation of both patients and cardiologist. The dose received by the cardiologist during interventional cardiology procedures is determi...

Abstract Background To evaluate current approaches to ionizing radiation by personnel working in urology operating room at all levels of health service Anatolia, Turkey. Methods A questionnaire was e-mailed including MDs different academic levels, between August and September 2020 The included demographic questions about radiation, exposure protection. Results Of the 173 (11.9%) respondents, 44...

composites with micro- and nano-metal fillers has attracted the attention of researchers for radiation shielding applications. Lead toxicity and heaviness have oriented extensive research toward the use of non-lead composite shields. The present study aimed to systematically review the efficiency of the composite shields of various micro- and nano-sized materials as composite shields have been ...

OBJECTIVES Leptospirosis has been documented in slaughterhouse workers around the world. Risk factors include smoking and drinking at work, and performing tasks such as cleaning offal. This paper examined risk factors for leptospirosis seropositivity in slaughterhouse workers in western Kenya. METHODS The study was conducted between May 2011 and October 2012. Questionnaires were used to colle...
