Ramı́rez-Páramo proved that under GCH for the class of compact Hausdorff spaces i-weight reflects all cardinals [A reflection theorem for i-weight , Topology Proc. 28 (2004), no. 1, 277–281]. We show that in ZFC i-weight reflects all cardinals for the class of compact LOTS. We define local i-weight, then calculate i-weight of locally compact LOTS and paracompact spaces in terms of the extent of ...

The importance of air pollution monitoring networks in urban areas is well known because of their miscellaneous applications. At the beginning of the 1990s, Berlin had more than 40 particulate matter monitoring stations, whereas, by 2013, there were only 12 stations. In this study, a new and free–of–charge methodology for the densifying of the PM10 monitoring network ...

BACKGROUND Recent findings suggest that exposure to outdoor air pollutants may increase the risk of allergic rhinitis. The results of these studies are inconsistent, but warrant further attention. The objective of the study was to assess the effect of relation between exposure to urban air pollution and the prevalence allergic rhinitis among school children. METHODS We conducted a nationwide ...

background and purpose: in this study, the air quality index and concentration of particles such as pm10 and pm2.5 were investigated in arak. materials and methods: to determine the concentration of pm10 and pm2.5, 60 samples were collected by laser tsi model 8520 in summer and winter 2012. the collection site was around arak city center. results: during the sampling period, as a matter of pm10...

The purpose of this study is to clarify the chemical characterization of PM2.5 and PM10 in diesel exhaust particles (DEP). Sampling of PM2.5 and PM10 in DEP was carried out in November 1999 using an automobile exhaust testing system at the National Traffic Safety and Environment Laboratory, with a diesel truck (engine type: direct injection, displacement: 7,961 cc, carrying weight: 2,020 kg, eq...

Abstract Buckwheat husks are a valuable source of carbon and show the potential to be used as an energy source. However, due low bulk density susceptibility compaction, it is beneficial use them in form co-pellets. The study presents comprehensive research detailing buckwheat husks’ for co-pelletization with oily (peanut husks) dusty (senna leaves) agri-food wastes, whereas effect material para...

The environmental control and management of municipal solid waste (MSW) dumping sites is considered one the sensitive challenges faced by executive municipalities. This especially true in Makkah due to gradual increase urban population visitors, with an overall MSW generation about million tons per year. Consequently, geo-environmental evaluation Kaakia site shed light on potential threats, ter...

Although the Philadelphia chromosome (Ph1) has been identified as an adverse prognostic factor in acute lymphoblastic leukemia (ALL), little is known about the incidence and clinical course of relapsed Ph1-positive ALL in children. The incidence was determined by screening of 170 consecutive children with first bone marrow relapse of ALL using the reverse transcriptase-polymerase chain reaction...
