A Review of the Bioaerosols in the Air-Conditioners Building
Get PDFBioaerosol is one of the sources that influence poor indoor air quality. Most buildings have air-conditioners (A.C.) to cool down the indoor building. However, the microorganism tends to grow, especially on the air conditioner filter, which may cause health problems called sick building syndrome and other bacterial diseases. Besides, temperature variation, relative humidity, and human occupancy in the A.C. building can also influence bioaerosol growth. Staphylococcus and Micrococcus were the most dominant genera detected in the A.C. building worldwide. Therefore, A.C. buildings need periodic services to avoid the spread of bioaerosol growth as it leads to adverse indoor air quality and to maintain human health

Study on Effect of Metallic Particle Contamination on the Break Down Voltage in Air Insulated System
Get PDFThe development of compressed gas insulated switchgear (GIS) and gas insulated transmission line (GITL) have progressed rapidly worldwide because of the excellent insulating and arc quenching properties of Sulphur Hexa Fluoride (SF6) gas. However, free conducting particles lower the corona onset and breakdown voltage of these systems. Under the action of the applied electric field in a coaxial geometry, conducting particles acquire charge and lift off from the outer enclosure when the electrostatic force from the electric field becomes equal or larger than the force due to gravity. Metallic particles move randomly in gas insulated systems under the action of electric field. The particle may remain in mid-gap or stay around the central conductor for several voltage cycles. Particle movement therefore plays a crucial role in determining the voltages withstand capability of GIS/GITL systems.Metallic conductors in gas insulated system are protected with a dielectric covering to mitigate the problem of particle initiated breakdown. Dielectric covering reduces the effect of surface roughness of conductors/duct and also increases the dielectric strength of the insulation system. Several researchers have developed computational models for particle movement in co-axial electrode system. These models however make assumptions about the particle charging process and charge exchange mechanism when a moving particle returns to the dielectric coated enclosure. Many experimental techniques have been proposed by researchers to explain the movement of particles in a co-axial bus-duct system. The experimental observations are also compared with the computational model. However, particle contamination in GIS is not fully understood and explained satisfactorily. Though SF6 is accepted universally as the best gaseous dielectric, it is considered to be a Greenhouse Gas. Hence research worldwide focuses on alternatives to SF6 gas without making much compromise on dielectric and other properties. In this context, use of SF6-N2 gas mixtures, containing less than 10% of SF6 gas is seen as a viable alternative for GITL. Hence the present study was taken up with this motivation
Global Regions, Biological Diversity, and Urban Land to Significance
Get PDFAs the world\u27s urban population is expected to grow by 2.5 billion over the next 30 years, urban land conversions are likely to become a bigger cause of habitat and species loss. It is vital to gain a better understanding of the potential locations and mechanisms for these biodiversity losses in order to mitigate their impacts. In this study, we assess the projected habitat loss due to urban land expansion for 30,393 species of terrestrial vertebrates from 2015 to 2050 across three shared socioeconomic pathway (SSP) scenarios using a recently developed suite of land-use projections. We discover that for about one-third (26–39%) of the species evaluated, urban land expansion is a contributing driver of habitat loss (5% of total loss). Urban land is a direct cause of species imperilment for up to 855 species (2–3% of those assessed), accounting for at least 25% of a net habitat loss of 10% or more. Sub-Saharan Africa, South America, Mesoamerica, and Southeast Asia are the major developing tropical regions where urban clusters are most likely to threaten species owing to anticipated expansion. Our findings imply that methods for reducing the effects of urban land could improve international agreements for the preservation of biodiversity. To mitigate the effects predicted by our analysis, cooperative, global action that prioritises vulnerable species and regions may constitute an effective tactic

Artificial Intelligence Approach for the Control of SPMSG Based Grid Connected WECS
Get PDFIn India, power plant requirement is rapidly increasing as non-conventional sources are in current need. Government financial aid plays important role for generator plant execution because of its tedious procedure. If the utilization of wind power production has to be doubled, then machines, turbines and converters are essential in two numbers. The research work includes parallel connection of two machines using star-delta-star transformer fashion resulting in six-phase permanent synchronous machine. This arrangement is more economical as the number of converters are reduced thereby increasing the efficiency by minimizing the switching losses. Initially rectifier setup is used wherein high frequency AC is converted to low frequency and maximum power point tracking is done with the aid of a converter. It is DC-DC conversion by decoupled DQ strategy. Later, it is again converted back to three phase AC so as to synchronize it to the grid. The system response is analysed by conventional PI controller by reducing the noise in the real & reactive power generation. Further, ANFIS-PI controller is implemented to improve the response of PI controller which is much essential for wind power generation. The MATLAB simulated results of PI controller system response and ANFIS-PI controller is presented in this paper
