ABSTRACT
This study used a pilot-scale submerged aerobic biofilter (SAB) to evaluate the co-treatment of domestic wastewater and landfill leachate that was pre-treated by air stripping. The leachate tested volumetric ratios were 0, 2, and 5%. At a hydraulic retention time of 24 h, the SAB was best operated with a volumetric ratio of 2% and removed 98% of the biochemical oxygen demand (BOD), 80% of the chemical oxygen demand (COD) and dissolved organic carbon (DOC), and 90% of the total suspended solids (TSS). A proposed method, which we called the "equivalent in humic acid" (Eq.HA) approach, indicated that the hardly biodegradable organic matter in leachate was removed by partial degradation (71% of DOC Eq.HA removal). Adding leachate at a volumetric ratio of 5%, the concentration of the hardly biodegradable organic matter was decreased primarily as a result of dilution rather than biodegradation, which was confirmed by Fourier transform infrared (FTIR) spectroscopy. The total ammoniacal nitrogen (TAN) was mostly removed (90%) by nitrification, and the SAB performances at the volumetric ratios of 0 and 2% were equal. For the three tested volumetric ratios of leachate (0, 2, and 5%), the concentrations of heavy metals in the treated samples were below the local limits.

Health care providers who want to make a difference in today's health care environment must support the idea of collaboration. To address the concerns of a university, a major medical center, and the community, a collaborative group shared their vision and developed creative strategies to serve the community. The critical components of this project included gaining the services of a nurse practitioner and nurse case manager, establishing physician liaison, assessing congregational health care needs, providing for both primary health and continuity of care needs, and maintaining the spiritual component of the faith community. Essential to the success of this program was the achievement of pastor and congregational support, enthusiasm, and involvement.

Adopting an open-minded attitude and the willingness to try new ideas are effective ways to cope with change and help reshape health care delivery. The willingness to let go of the relatively stable, nonthreatening situation and embrace a new, ambiguous environment will promote personal and professional possibilities. Keys to organizational success include: accept change; redefine the business of the organization; encourage high-performing, flexible individuals; and foster a sense of team learning and community. The changes in health care delivery, the complexity of patient care and the blending roles all provide new options for nurses.

The creation of Vision: A Professional Model for Nursing Practice followed an evolutionary process of development over a 20-year time span. The nurse/patient relationship was the central theme of this practice model and implies that nursing excellence, driven by knowledge, research, empowerment and accountability, would result in positive outcomes for patient care and create a culture of independent, caring professional nurses.

One of the most important evolutionary forces in transforming health care is the shift from management to leadership in nursing. The transformational leader will be the catalyst for expanding a holistic perspective, empowering nursing personnel at all levels and maximizing use of technology in the movement beyond even patient-centered health care to patient-directed health outcomes.

The effect of temperature on the extraction of FE(III) by dehydrated castor oil fatty acids (DCOFA) has been studied in the temperature range 283-313 K at 1.0M constant ionic strength (NaClO(4)). The temperature dependence of the conditional constant of extraction is given in the form: ln K(ext)=31.95 - 12800(1/T). Also, it was found that the average thermodynamic parameters, DeltaH degrees (ext), DeltaG degrees (ext), and DeltaS degrees (ext) are 106.5 kJ/mole, 27.3 kJ/mole, and 0.3 kJ. mole(-1).K(-1), respectively. The extracted species in toluene solution were identified as FeR(3).HR and Fe(OH)R(2), where HR represents the fatty acid used.
