Bioremediation techniques–classification based on site of application: principles, advantages, limitations and prospects

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (bioremediation) has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation. However, cost of on-site installation of equipment, and inability to effectively visualize and control the subsurface of polluted sites are of major concerns when carrying out in situ bioremediation. Therefore, choosing appropriate bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful bioremediation project. Furthermore, the two major approaches to enhance bioremediation are biostimulation and bioaugmentation provided that environmental factors, which determine the success of bioremediation, are maintained at optimal range. This review provides more insight into the two major bioremediation techniques, their principles, advantages, limitations and prospects.

Reproductive biology, length‐weight relationship and relative condition of pond raised <i>Tilapia zilli</i> (Gervais)

In ‘runted’ populations of Tilapia zilli positive correlations were found between maturation stages and the following: gonadosomatic index, gonad weight, fish weight and fish length. The minimum size at maturity was 9·0 cm in males and 11·0 cm in females. The mean fecundity in the ‘stunted’ females was 2359 eggs and it increased with length ( L ) weight (HO and depth ( D ) of the fish. There was, however, no correlation between fecundity and egg size. The results indicated that growth in this ‘stunted’ T. zilli population was not isometric. The relative condition factor ( Kn ) which approached one indicates good condition.

National surgical, obstetric, anaesthesia and nursing plan, Nigeria

Recent evidence suggests that strengthening surgical care within existing health systems will strengthen the overall health-care system. However, Nigeria's national strategic health development plan 2018-2022 placed little emphasis on surgical care. To address the gap, we worked with professional societies and other partners to develop the national surgical, obstetric, anaesthesia and nursing plan 2019-2023. The aim was to foster actions to prioritize surgical care for the achievement of universal health coverage. In addition to creating a costed strategy to strengthen surgical care, the plan included children's surgery and nursing: two key aspects that have been neglected in other national surgical plans. Pilot implementation of the plan began in 2020, supported by a nongovernmental organization with experience in surgical care in the region. We have created specific entry points to facilitate the pilot implementation. In the pilot, an electronic surgery registry has been created; personnel are being trained in life support; nurses are being trained in safe perioperative care; biomedical technicians and sterile supplies nurses are being trained in surgical instrument repair and maintenance; and research capacity is being strengthened. In addition, the mainstream media are being mobilized to improve awareness about the plan among policy-makers and the general population. Another development partner is interested in providing support for paediatric surgery, and a children's hospital is being planned. As funding is a key challenge to full implementation, we need innovative domestic funding strategies to support and sustain implementation.

Incivility among nursing faculty: A multi-country study

Preliminary study on the aspects of the biology of snakehead fish parachanna obscura (günther) in a Nigerian wetland

Between October 2000 and March 2001, a preliminary study on the aspects of the biology of Parachanna obscura, was carried out. Sex ratio revealed female preponderance (÷2 = 4.733, df = 1, P < 0.05). There was no variation in sex ratio during the wet season but there were more females than males in the dry season (÷2=4.735, df = 1, p =
