Influence of transient radiation properties upon heating rates

This paper shows that the readiation properties of copper change drastically with temperature and they are influenced by environment, heating rate and initial surface condition. An approach is developed which takes into account the transient radiation properties when calculating heating rates

Fate of indeterminate microbial keratitis

Background: Previous published literature has shown that there is no significant difference between outcomes of culture positive and culture negative infective keratitis. This study was done to find the outcome in cases of indeterminate keratitis in our institute. Purpose was to highlight the fate of indeterminate microbial keratitis.Methods: Patients presenting to cornea services of ABVIMS and Dr. RML hospital from February 2017 to April 2021 were evaluated for demographic and microbiological assessment, clinical presentation and management.Results: The 188 out of 310 cases were microbiologically positive. No organism could be detected in 122 cases. Clinical prognosis is worse in cases of indeterminate keratitis.Conclusions: Cases with indeterminate microbial keratitis do not show timely and appropriate response which leads to spread of infection resulting in more complications and less CDVA

Entwicklung von Anbausystemen für Linsen im ökologischen Landbau

After commercial cropping of lentils (Lens culinaris) expired in Germany 50 years ago, a revival was observed on a small regional scale. Several field trials aimed at the development of lentil cropping systems to make lentils a more popular crop in German organic farming. One of the trials was set up to identify suitable companion crops and cropping ratios for lentils in mixed cropping systems. Suitable cropping systems in terms of yield (up to 1.8 t ha-1) were combinations with barley (Hordeum vulgare), wheat (Triticum aestivum) and buckwheat (Fagopyrum esculentum) in a ratio of 180 : 60 seeds ha-1 (lentil:companion crop), and with wheat or oats (Avena sativa, 1 : 3) in terms of lodging. As lentil and wheat grains were difficult to separate after harvest, other varieties with shape and thousand grains mass more different from each other might allow the combination of wheat and lentils. According to the results of other trials, development of modern lentil cropping systems has to include the issues of sowing time (early sowing date), weed control, and varieties adapted to local conditions

ASSESSMENT OF LUNG CANCER RISK REDUCTION BEFORE AND AFTER ADOPTION OF A RADON RESISTANT NEW CONSTRUCTION (RRNC) BUILDING CODE STANDARD IN AMITY TOWNSHIP, PA

Radon 222 (222Rn) is an element found in the soil surrounding many homes in the United States. It is formed during the natural radioactive decay of uranium. Radon gas moves into homes through cracks or holes in the foundation and can then be inhaled by the home residents. Inhaled radon is the second leading cause of lung cancer after smoking and is the leading cause in non-smokers. Radon-Resistant New Construction (RRNC) reduces residential radon exposure and reduces the risk of developing lung cancer. Several townships and municipalities in Pennsylvania have adopted ordinances that require new houses to be built using RRNC. To evaluate the effectiveness of RRNC in reducing radon-related lung cancer risk, residential radon concentrations were compared in homes with and without RRNC in a Pennsylvania township that has adopted the RRNC statue into their building codes. This study utilizes a risk-based decision framework to assess the lung cancer risk reduction in Amity Township, PA after adoption of a RRNC standard. The work primarily uses data on residential radon measurements that have been compiled by the Pennsylvania Department of Environmental Protection (PADEP). These measurements are reported to the PADEP by certified testers and homeowners. The results from the initial analysis on the radon concentrations will be used in a peer-reviewed lung cancer risk model to examine the reduction in risk for residents of RRNC homes versus non-RRNC homes. This work also uses publicly available measurable characteristics of health indicators such as lung cancer incidence and mortality collected from and/or about Amity Township, PA. Because the smoking rates were not available down to the township level, the smoking rates of Berks County, PA (where Amity Township is located) will be utilized. The health and economic benefits of adopting an RRNC standard will also be reviewed as part of the decision process
