RNA-based microbiological analyses, e.g., transcriptome and reverse transcription-quantitative PCR, require a relatively large amount of high quality RNA. RNA-based analyses on microbial communities in deep-sea hydrothermal environments often encounter methodological difficulties with RNA extraction due to the presence of unique minerals in and the low biomass of samples. In the present study, ...

Coal power stations as well as waste incinerators produce humid acid gases which condensate in industrial chimneys. These condensates may cause corrosion of the internal cladding made of stainless steels, nickel base alloys or non metallic materials. In the aim of polluting emission reduction and material optimal choice, it is necessary to determine all the phenomena which occur throughout the ...

The Global Burden of Disease Study estimated that in 2010 there were 6.3, 3.5 and 3.2 million deaths attributable to tobacco smoking, household air pollution from solid fuels and ambient particulate matter pollution, respectively. The inhalation of polluted air is the leading risk factor for death and disability globally. The adverse effects of these three categories of air pollution impact mos...

The aims of this study are to enhance the performance of a solar chimney power plant (SCPP), investigate utilization of thermal energy storage (TES) and analyze the environmental impact of the SCPP in providence of Isfahan, Iran. To achieve these goals, multi-stage numerical simulations during twenty-four hours of a day are performed in climate condition of Isfahan province (central region of I...

Parkinson’s disease (PD) is neurodegenerative disorder characterized by the progressive loss of the dopaminergic neurons in the substantia nigra pars compacta which innervates the dorsal striatum. Using haloperidol induced catalepsy in rat and muscle rigidity in mice effects of aq. extract of Ocimum sanctum (OSEaq) were studied. Haloperidol was administered to induce either short term model (0....

This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

Chimney swifts (Chaetura pelagica) are highly manoeuvrable birds notable for roosting overnight in chimneys, in groups of hundreds or thousands of birds, before and during their autumn migration. At dusk, birds gather in large numbers from surrounding areas near a roost site. The whole flock then employs an orderly, but dynamic, circling approach pattern before rapidly entering a small aperture...
