Background: Segmental defects in long bones from any cause often present significant challenge to trauma reconstruction and orthopaedic surgeons. Various options for bridging extensive segmental bone defects have been tried in attempt to find the best method to achieve that. In developing countries, the choices are limited due to unavailability and high cost of sophisticated implants and materials, and the relative lack of expertise and equipment required to carry out some of these procedures.

Setting: University of Port Harcourt Teaching Hospital Port Harcourt, Nigeria.

Case & Review: This article reports the first use of a free vascularised fibular graft to bridge a long segmental defect in the radius following tumour resection in a tertiary hospital in Nigeria and perhaps the sub region and reviewed the feasibility of such procedure  using basic simple tools

Conclusion: Free vascularised fibular graft is an option for bridging large bone defects in Nigeria as long as the required expertise, capacity and facilities are available. It can be less complicated and more economical in well selected patients in the long run compared to other complex reconstruction methods especially if the expertise and basic resources is available.

Leather processing is one of the hazardous red listed industry which produce large quantity of effluent with high organic load and bulk quantity of solid wastes. The wastes generated from the tannery industry are most concerned and management of this waste should be in ecofriendly manner. Composting is a method of biological decomposition of organic wastes by microorganisms under controlled conditions. In order to optimize the process parameters a windrow method of composting was carried out along with other organic wastes such as poultry waste and coirpith. The results show that electrical conductivity (EC) of the compost was 2.28 dSm-1, pH 7.31 and C/N ratio of 16.97. Concentration of Chromium in the compost was decreased and it was complied with the standards of the Indian limits thus the compost made from the tannery sludge suitable for in Agriculture. The maturity of the composted semi-finished tannery sludge (SFTS) was confirmed through maturity tests such as humification index and qualitative tests including starch iodine and sulphide tests. The germination index for radish seed was 86%, which indicates the absence of toxic compounds in the tannery sludge compost.

The present study investigated the effects of EMS on crop phenotypes on four mungbean varieties viz., Co (6), Co (7), VRM and VBM. The germination percentage was affected by EMS treatment with increase in dose or concentration of mutagen. The doses can be determined by establishing the LD 50 value for the mutagen to be used. The expected LD50 values of EMS for Co (6), Co (7), VRM 1 and VBM 3 are 37.15, 39.81, 28.18, 32.35 respectively. Several plant traits like germination percentage, survival percentage, root length, shoot length, was affected with the mutagenic treatments. Co7 shows better germination and survival percentage compared to other genotypes. Hence Co7 chosen for establishment of TILLING population.

In our daily life, we often come across various problems related to the high dimensionality of data. In such type of problems irrelevant and superfluous data along with useful data is also present. Thus, dimensionality reduction has found wide applications in data analysis and management. In recent years the issue of dimensionality reduction in a fuzzy situation has also gained importance and has invited attention of researchers. The various techniques and theories have been developed by them to solve these types of problems. Some of these techniques based on probabilistic approach and others are non-probabilistic approach.

For finding coherent and logical solution to various real life problems containing uncertainty, impreciseness and vagueness, fuzzy soft set theory is gaining significance. In this paper concept of fuzzy soft set has been defined as hybridization of fuzzy set and soft set theory. A new technique is proposed to convert the soft set table into fuzzy soft set table and has been applied in dimension reduction of big data.  An application of fuzzy soft set has also studied in Medical Diagnosis following Sanchez’s approach.

The present paper is a mini review of the increasing soil pollution in the environment and the possible handy options available, to curb its rate. Soil being a non-renewable resource, must be protected from all types of pollutants. The health of all life forms is associated with the health of soil. Any degradation in the quality of soil can significantly produce many undesirable changes in the environment. Adoption of suitable strategies to protect our motherland from contamination is must for all of us to save ourselves and continuation of natural cycles in the ecosystem.
