Air pollution has become a major problem in urban areas due to increasing industrialization and urbanization. In this study ambient concentrations of PM1 metal as well source contributions were identified quantified by using Positive Matrix Factorization (PMF) receptor modeling the Metropolitan Area Porto Alegre, Brazil. The samples collected on PTFE filters from December 2012 2014 two sampling...

The megacity of Beijing has experienced frequent severe fine particle pollution during the last decade. Although the sources and formation mechanisms of aerosol particles have been extensively investigated on the basis of ground measurements, real-time characterization of aerosol particle composition and sources above the urban canopy in Beijing is rare. In this study, we conducted real-time me...

We develop a geometric approach to the study of (s,ms−1)-core and (s,ms+1)core partitions through the associated ms-abaci. This perspective yields new proofs for results of H. Xiong and A. Straub (originally proposed by T. Amdeberhan) on the enumeration of (s, s + 1) and (s,ms− 1)-core partitions with distinct parts. It also enumerates the (s,ms+1)-cores with distinct parts. Furthermore, we cal...

OBJECTIVE The management of patients with non-small cell lung cancer (NSCLC) with intrapulmonary metastases (PM) is controversial. In TNM classification, PM are designed as T4 when in the same lobe of the primary tumour (PM1) and M1 when in a different lobe(s) (PM2). Some authors have questioned the negative prognostic impact of PM. The present study assessed prevalence, correlation with clinic...

Shanghai, with a population of over 20 million, is the largest mega-city in China. Rapidly increasing industrial and metropolitan emissions have deteriorated its air quality in the past decades, with fine particle pollution as one of the major issues. However, systematic characterization of atmospheric fine particles with advanced measurement techniques has been very scarce in Shanghai. During ...

The main purpose of the present work was to evaluate efficiency gasification process three different types agro-forest biomass residue (rapeseed, softwood, and sunflower husks) along with characterization size-segregated particulates’ emissions. experiments were carried out in a drop tube furnace (DTF), using two gasifying agents (O2/N2 O2/N2/CO2) at atmospheric pressure constant temperature 10...

Indinavir (IDV) is a potent and selective human immunodeficiency virus type 1 (HIV-1) protease inhibitor (PI) widely used in antiretroviral therapy for suppression of HIV, but its effects on the immune system are relatively unknown. Recently, it has been reported that PIs inhibit lymphocyte apoptosis. In the present study we have investigated the effects of ex vivo addition of IDV on lymphocyte...

BACKGROUND Air pollution is a common alibi used by adolescents taking up smoking and by smokers uncertain about quitting. However, environmental tobacco smoke (ETS) causes fine particulate matter (PM) indoor pollution exceeding outdoor limits, while new engines and fuels have reduced particulate emissions by cars. Data comparing PM emission from ETS and a recently released diesel car are presen...

Soft-bottom macrobenthic diversity and community structure were assessed at Mumbai and Jawaharlal Nehru ports during three different periods between 2001 and 2002 (November 2001 post-monsoon 1, April/May 2002 pre-monsoon, and October 2002 post-monsoon 2). A total of 43 macrobenthic invertebrate species belonging to five phyla were recorded. Macrofaunal abundance (PM1 186, PreM 106, and PM2 31 i...
