Prerequisite: FSCN 302. An examination of prevention as the primary community-based strategy for fire protection. The objective is to design, implement, and manage programs addressing community risks; administer prevention programs; and influence change and development of legislation, regulation, and policy. Emphasis is on applying principles to anticipate problems and develop strategies for fire prevention. Topics include community risk reduction, codes and standards, inspections and plans review, incident investigation, fire-prevention research, and the relationship of master planning to fire prevention. The cultural, economic, governmental, nongovernmental, and departmental influences on fire prevention are also explored.

The nanocrystallite has the finite number of the oscillation modes. Their number increases proportionally to a cube of the characteristic size. Thus the oscillation spectrum of nanocrystal becomes discrete, and the separate modes of oscillations do not interact with each other, that considerably strengthen all phonon modulated processes in a crystal. Covering of such a nanocrystallite with the shielding surface of a material with the higher nuclear weight will allow creating the phonon resonators whose oscillation modes will represent the standing waves and, will be amplified by the resonant manner. The composites made of phonon resonators will allow producing a perspective functional material for the electronics with adjustable structure and properties. Some new mechanism of HTS based on phonon resonators is proposed.
CTAB (cetyltrimethylammonium bromide) coated manganese ferrite (MnFe2O4), nickel ferrite (NiFe2O4) and zinc ferrite (ZnFe2O4) nanoparticles with crystallite sizes of 23 nm, 15 nm, and 28 nm respectively were successfully synthesized by a facile co-precipitation method. The presence of CTAB on the surface of the nanoparticles was confirmed by the Transmission Electron Microscope (TEM) and Fourier Transform-Infrared spectrum (FT-IR). The magnetic study shows a high saturation magnetization of 46 emu/g (MnFe2O4), 59 emu/g (NiFe2O4) and 55 emu/g (ZnFe2O4) which indicates the Fe-O-Fe super-exchange interaction driven by the synergistic influence of magnetocrystalline anisotropy and cation distribution. The Field Cooling (FC) and Zero Field Cooling (ZFC) curves confirmed the superparamagnetic nature of all the samples. The induction heating study elucidates the efficiency of heat generation (>42°C) in all samples showing an exceptionally high specific absorption rate (SAR) of 480 Wg-1, 684 Wg-1, 586 Wg-1 at 2 mg/ml in which CTAB-NiFe2O4 nanoparticles shows the highest efficiency. This is attributed to the co-dependent factors: size, saturation magnetization and Neelian relaxation loss mechanism. This comparative study discussed on the collaborative influences of structural motifs and magnetic properties that engendered the effectiveness of heat generation making it viable for hyperthermia application.

Inorganic fertilizers along with high yielding varieties have contributed immensely for success of green revolution. Increasing pressure towards food production globally demands unconscientious fertilizer usage in future as well. Nitrogenous fertilizers are the extensively used fertilizers but also suffer huge losses from agriculture ecosystem due to faster rate of release which is not synchronized with crop demand. Thus resulting in low nitrogen use efficiency. In order to have a sustained release of nitrogen from fertilizer, nanoparticle coated with urea is an effective option. We report urea coated hydroxyapatite based nanofertilizer and its performance on aerobic paddy. In this study hydroxyapatite (HA) nanoparticles were synthesized by adding orthophosphoric acid to calcium hydroxide solution under constant vigorous stirring. Saturated urea solution was added to the HA particle suspension and was stirred continuously for 12 hours for surface modification. The urea modified HA particles were washed and dried at 65ºC. Hydroxyapatite nanoparticles (HA) and urea coated hydroxyapatite nanoparticles (UHA) were characterized using Dynamic Light Scattering (DLS), Scanning Electron Microscope (SEM), Powder X-ray Diffraction (PXRD) and Fourier Transform Infrared (FTIR) Spectroscopy. Nitrogen content of UHA was analyzed using Kjeldahl method. Nitrogen content of UHA particles was found to be 36% and Zeta potential was 165.0 mV indicating stable nanodispersion. PXRD pattern of UHA particles indicated the presence of peaks due to hydroxyapatite and urea. SEM images of UHA particles exhibited oblong structures resembling rice grains with diameter less than 90 nm. FTIR spectroscopy showed prominent peaks around γmax/cm–1 1041 indicating phosphate group in hydroxyapatite and γmax/cm–1 3336 and 3432 indicating presence of urea. Synthesized nanofertilizer was evaluated on aerobic paddy under completely randomized design and was compared with recommended dose of conventional urea (100kgN/ha) in aerobic paddy. Nanofertilizer at 25% of recommended dose recorded highest grain yield. Nanofertilizer@ 50% dose showed similar performace to 100% dose of conventional urea. The results indicate amount of fertilizer application into soil can be reduced than regular dosage with nanofertilizer without affecting the yield. This will reduce environmental pollution of water and soil without compromising agricultural production.

Widely spread of chemically industry producing many types of environmentally pollutants (e.g dyes, herbicides, pesticides, insecticides, drugs, bacteria and others), most of these pollutants reach our drinking water resources, different strategies have been followed to purify contaminated water, one of the low-cost technology is using semiconductors as catalyst for photodegradation of water-organic contaminants. TiO2 nano- and microparticles have been used for photo-degradation of widely spread water organic contaminants. Due to its wide band gap (~3.2 eV) TiO2 photo-catalytic activity is limited to shorter wavelengths only (UV region). As only ~4% of the solar spectrum falls in the UV region, smaller bandgap semiconductors (e.g. CdS, with 2.3 eV) are used to sensitize TiO2 particles. The TiO2/CdS system has been used as a catalyst in water purification by photo-degradation of organic contaminants such as methyl orange and Phenazopyridine (Medically active compound). However, the TiO2/CdS system is unstable under photodegradation conditions yielding hazardous Cd2+ ions. Alternative ZnO nanoparticles naked and substrate to different materials like (clay, sand, and activated carbon) were used in photodegradation process; also natural dyes (anthocyanin & Curcumin) were used as a sensitizer for the TiO2 nanoparticles. The different prepared nano-catalyst systems were used to photo-degrade various contaminants of water and soil, such as methyl orange, phenazopyridine, paracetamol, phenols, and halo-phenols, with solar radiation. Furthermore, the ZnO nanoparticles were used in water purification and disinfection (from bacteria that cause water contamination) by complete mineralization under solar light. Different reaction parameters (such as catalytic efficiency, effects of catalyst concentration, catalyst recovery, contaminant concentration, temperature, pH and complete mineralization) will be discussed together.
