the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...
Textile industry wastewater (TIWW) is considered as one of the worst polluters our precious water and soil ecologies. It causes carcinogenic, mutagenic, genotoxic, cytotoxic allergenic threats to living organisms. TIWW contains a variety persistent coloring pollutants (dyes), formaldehyde, phthalates, phenols, surfactants, perfluorooctanoic acid (PFOA), pentachlorophenol different heavy metals ...
abstract nowadays, industries cannot play a crucial role in national and international competitions. the tourism industry is no exception. tourism industry development as the most important economic sector and income generation is one of the key challenges of economic development in the world. therefore, countries were successful that take advantage of the capabilities of tourism sector using ...
Background and purpose: Fish is consumed by humans for its nutritional properties, but accumulation of heavy metals in fish can pose serious health hazards. The aim of this research was to investigate the concentration of heavy metals in the muscle and liver of common carp in Zarivar wetland, Iran. Materials and methods: A cross-sectional study was conducted in which carps were caught from Z...
the long term effects of sewage water irrigation on soil properties and heavy metal concentrations at rohtak city, haryana (india) was investigated. at each location, soil samples were collected from the upper layer (0-10cm) for determination of various physico-chemical parameters. heavy metals (pb, cu, mn, zn, cd, ni, and fe) were also determined. the chemical analysis of sewage effluent showe...
In recent years, environmental pollution by coal mining is a long-established human activity affecting all levels of life with various environmental impacts by generating heavy metals. The presence of heavy metals even in trace amount is toxic and detrimental to all living organisms. The coal mine area in Bokaro is one of the “Toxic Hotspot” in India. Bacteria have evolved uptake and efflux mec...
The seesaw model of heavy and light Majorana neutrinos and its low-energy effective theory are studied, when the number of heavy neutrinos is equal to or less than the number of light lepton generations. We establish a general relationship between the high-energy parameters and the low-energy observables involving only the light fields. It is shown how low-energy measurements of the properties ...
Financial evaluation and strategic analysis have long been considered two distinct approaches to evaluating new capital initiatives. An emerging valuation approach, known as real options, attempts to align finance and strategy through a new perspective: The value of an asset lies not only in the amount of direct revenues that it is expected to generate, but also in the options that it creates f...
