Wastewater treatment using bamboos in constructed wetlands: experiences and future perspectives.

Wastewater treatment using constructed wetlands (CWs) based on natural wetlands constitute a viable alternative with excellent cost and benefit, presenting themselves as efficient technologies in the secondary and tertiary treatment of wastewaters with low implementation, operation, and maintenance costs. The present study aims to evaluate the use of bamboo species, as an alternative to macrophytes, frequently used in CWs, through bibliometric analysis, besides to a review based on case studies. The maps generated by the VOSviewer software and by the analyses of the Web of Science and Scopus databases allowed for a review of typical concepts of CWs, in addition to revealing potential benefits of using bamboos in CWs, such as their hyperaccumulation capacity and bioproduct generation.

Hybrid constructed wetlands integrated with microbial fuel cells and reactive bed filter for wastewater treatment and bioelectricity generation.

The present study aimed to develop a pilot-scale integrated system composed of anaerobic biofilter (AF), a floating treatment wetland (FTW) unit, and a vertical flow constructed wetland coupled with a microbial fuel cell (CW-MFC) and a reactive bed filter (RBF) for simultaneously decentralized urban wastewater treatment and bioelectricity generation. The first treatment stage (AF) had 1450 L and two compartments: a settler and a second one filled with plastic conduits. The two CWs (1000 L each) were vegetated with mixed plant species, the first supported in a buoyant expanded polyethylene foam and the second (CW-MFC) filled with pebbles and gravel, whereas the RBF unit was filled with P adsorbent material (light expanded clay aggregate, or LECA) and sand.

To estimate sodium consumption via cow milk, orientations for exceptional situations when neither breastfeeding nor infant formula is possible were considered.

Floating treatment wetlands in domestic wastewater treatment as a decentralized sanitation alternative.

Floating treatment wetlands (FTW) are technologies that have stood out for their efficiency, ease of installation and maintenance. They consist of macrophytes emerging in a floating structure that keep the plant roots in direct contact with the effluent regardless of the water flow variation over time, allowing the removal of pollutants by various processes. The application of FTWs for the treatment of domestic wastewater has the advantage of low costs in terms of removing nutrients and at the same time reducing the cost of maintenance and energy consumption when compared to the conventional centralized treatment of effluent.

Root growth and nutrient removal of Typha domingensis and Schoenoplectus californicus over the period of plant establishment in a constructed floating wetland.

Constructed floating wetlands have been employed worldwide to treat effluents and to ameliorate water quality of water resources. However, the period of macrophyte establishment into the hydroponic functioning has not been specifically addressed. This paper reports root growth and nutrient removal of Typha domingensis and Schoenoplectus californicus in a floating structure without growth substrates over the period of 11 weeks of macrophyte establishment.

Bureaucracy and the balanced scorecard in health care settings.

Purpose: We explore the relationship between the balanced scorecard (BSC) and neo-bureaucracy by investigating whether the operationalization of the BSC incorporates "neo-bureaucratic" ideas and whether the BSC implemented in a Portuguese Local Health Unit (LHU) demonstrates a neo-bureaucratic approach.

Design/methodology/approach: We conduct semi-structured interviews with LHU staff and analyse documents to assess whether features of bureaucratic organization were evident in the use of a BSC by the LHU.

Findings: We found nine bureaucratic features evident in the LHU's BSC.

Milk types and their contribution to daily sodium and calcium intake.

Low calcium consumption and high sodium intake among adolescents is a serious public health problem. Thehigh content and bioavailability of calcium in milk makes it the best choice for meeting the Dietary Reference Intakes (DRIs) for calcium. Since milk also contributes to sodium intake, programs promoting milk consumption should be preceded by initiatives to reduce its sodium content.

sternoclavicular osteoarthritis.

Sternoclavicular arthritis is an unusual osteoarticular infection and can be associated with severe complications. Cases in a paediatric population are infrequently reported, making this approach challenging. is an agent of increasing recognition in paediatric invasive infections, principally below 2 years of age.

Integrating ontogenetic shift, growth and mortality to determine a species' ecological role from isotopic signatures.

Understanding species linkages and energy transfer is a basic goal underlying any attempt at ecosystem analysis. Although the first food-web studies were based on gut contents of captured specimens, the assessment of stable isotopes, mainly δ13C and δ15N, has become a standard methodology for wide-range analyses in the last 30 years. Stable isotopes provide information on the trophic level of species, food-web length, and origin of organic matter ingested by consumers.
