The efficacy of iron(II) sulfide (FeS)-based autotrophic denitrification in simultaneous nitrogen and phosphorus removal from wastewater was studied with batch experiments. It was efficient at a wide pH range of 5-9, and temperature range of 10-40 °C. The concentrations of NH₄⁺-N, Mg²⁺ and HCO₃⁻ in the wastewater should be kept over 7.8, 0.24 and 30 mg L⁻¹ for efficient nitrate (NO₃⁻-N) reducti...

In 1965, after proposals seeking Science Development Program (SDP) grants had been made to the National Science Foundation by both CIT and WRU, there was increased pressure from various quarters (including the NSF) for the merger of the two institutions. Ultimately, the NSF granted $3.5 million each to CIT and WRU, essentially contingent on their eventual federation. Of this, a total of $2.6 mi...

Although various pharmacological treatments are available for persons suffering with positive psychotic symptoms, these symptoms often continue to occur even when medications are taken. Traditional psychosocial methods such as family therapy and cognitive-behavioral alleviate symptoms in this population, but interventions are often lengthy and difficult. The present paper argues that directly t...

The main objective of this study is to justify the necessity of developing a conceptual framework on risk-taking behaviours of adolescents while using the Internet in Bangladesh. In all, 507 adolescents participated in a survey on risk-taking behaviours using the Internet. The risks were classified into three categories, namely, risk-taking behaviours in general, risk-taking behaviours due to c...

The measurement of 16-androstene steroids in submaxillary salivary glands is a potentially good way to estimate boar taint. The objective of this work was to identify factors regulating the concentrations of these steroids in salivary glands. Large White x Pietrain male pigs were divided into four treatments: T-1, intact untreated (n = 18); T-2, intact treated with porcine somatotropin (pST, n ...
