Biofilter aquaponic system for nutrients removal from fresh market wastewater

Aquaponics is a significant wastewater treatment system which refers to the combination of conventional aquaculture (raising aquatic organism) with hydroponics (cultivating plants in water) in a symbiotic environment. This system has a high ability in removing nutrients compared to conventional methods because it is a natural and environmentally friendly system (aquaponics). The current chapter aimed to review the possible application of aquaponics system to treat fresh market wastewater with the intention to highlight the mechanism of phytoremediation occurs in aquaponic system. The literature revealed that aquaponic system was able to remove nutrients in terms of nitrogen and phosphorus

Genetic conservation through effective utilization of the improved indigenous chicken breeds by rural households in Nigeria

SUMMARY. Our collection and genetic characterization of various indigenous chicken genotypes in Nigeria started in 1984 at the National Animal Production Research Institute, Shika, Zaria, (Shika Brown) in 1994 at the Federal University of Agriculture, Abeokuta, Nigeria (FUNAAB) and in 2014 in Obafemi Awolowo University, Ile-Ife (FULANI). Collections were screened and characterized for genetic improvement and effective utilization by rural households in Nigeria With the financial and technical support of the Bill and Melinda Gates Foundation and the International Livestock Research Institute, Ethiopia, respectively, improved chicken genotypes were developed and evaluated alongside some other tropically adapted chicken breeds. A total of six improved tropically adapted chicken breeds (three Nigerian – Shika Brown, FUNAAB alpha and Fulani; three imported – Kuroiler, Sasso and Noiler) were tested for 52 weeks on-farm, across five agro-ecological zones of Nigeria and on-station in a public University farm and a private farm in Ogun and Oyo States, respectively. Results showed the Nigeria’s improved Indigenous chicken breed, the FUNAAB-Alpha, to be of comparable performance with the three imported breeds. It has met with high acceptance and demand after exhibition of the six breeds during the 2017 Science and Technology Expo in Abuja, Nigeria

Classification criteria for cervical radiculopathy: An international e-Delphi study.

BACKGROUND: Establishing a set of uniform classification criteria (CC) for cervical radiculopathy (CR) is required to aid future recruitment of homogenous populations to clinical trials. OBJECTIVES: To establish expert informed consensus on CC for CR. DESIGN: A pre-defined four round e-Delphi study in accordance with the guidance on Conducting and Reporting Delphi Studies. METHODS: Individuals with a background in physiotherapy who had authored two or more peer-reviewed publications on CR were invited to participate. The initial round asked opinions on CC for CR. Content analysis was performed on round one output and a list of discrete items were generated forming the round two survey. In rounds two to four, participants were asked to rate the level of importance of each item on a six-point Likert scale. Data were analysed descriptively using median, interquartile range and percentage agreement. Items reaching pre-defined consensus criteria were carried forward to the next round. Items remaining after the fourth round constituted expert consensus on CC for CR. RESULTS: Twelve participants participated with one drop out. The final round identified one inclusion CC and 12 exclusion CC. The inclusion CC that remained achieved 82% agreement and was a cluster criterion consisting of radicular pain with arm pain worse than neck pain; paraesthesia or numbness and/or weakness and/or altered reflex; MRI confirmed nerve root compression compatible with clinical findings. CONCLUSIONS: The CC identified can be used to inform eligibility criteria for future CR trials although caution should be practiced as consensus on measurement tools requires further investigation

A time for action: Opportunities for preventing the growing burden and disability from musculoskeletal conditions in low- and middle-income countries

Musculoskeletal (MSK) conditions cause an enormous global burden, and this is dramatically increasing in developing countries, particularly due to rapidly ageing populations and increasing obesity. Many of the global non-communicable disease (NCD) initiatives need to expand beyond the traditional ‘top four’ NCD groups by incorporating MSK diseases. It is critical that MSK initiatives in developing countries integrate well with health systems, rather than being stand-alone. A better inclusion of MSK conditions will avoid doubling of efforts and wasting of resources, and will help to promote a more streamlined, cost-effective approach. Other key opportunities for action include the following: ensuring the principles of ‘development effectiveness’ are met; strengthening leadership and commitment; building the research, information and evidence base; and reducing the incidence and disability of MSK conditions through better prevention. Each of these elements is necessary to mitigate and reduce the growing burden from the MSKs
