The pedal-operated maize dehuskar-sheller was ergonomically evaluated with ten male agricultural operators to assess the physiological costs of operation. The Heart Rate, Oxygen Consumption Rate and energy expenditure rate were used for assessment of physiological cost for the operation of the pedal operated maize dehuskar sheller. The Heart Rate and Oxygen Consumption Rate were measured with Computerized Ambulatory Metabolic Measurement System K4b2. The energy expenditure rate was calculated based on the Oxygen Consumption Rate during the operation. The mean working heart rate, mean working Oxygen Consumption Rate and mean working energy expenditure rate of all subjects during the operation of maize dehusker sheller were found to be 139 (± 22.01) beats/min, 1.40 (± 0.20) l/min and 6.83 (±1.07) kcal/min, respectively. Based on energy expenditure rate, the operation of pedal operated maize dehusker sheller was found under ‘Heavy’ work category.

Food security is critical to the economic, social, religious, political and cultural development Worldwide. It plays a great role in economic growth, poverty reduction and sustainable development in Kenya. A study was carried out in Kilifi South sub-county in the coastal areas of Kenya, one of the areas where food insecurity incidences are prevalent. The study assessed the effect of indigenous knowledge on food security status among smallholder farming communities through interview schedules. Non-experimental design using descriptive survey was adopted for the study. The data were analyzed using descriptive statistics and multiple regression. The results indicated that 80% of all the farmers were food insecure. Those who practiced indigenous knowledge were 20% food secure and 80% food insecure. The farmers who had planted fast-growing crops were 9% food secure while the ones who practiced traditional water conservation were 1% food secure and those who planted traditional seeds were 10% food secure. Farmers who practised integrated pest management were 11% food secure while those who planted drought-resistant crops were 9% food secure. There was a significant (P= .05) positive relationship between food security and practice of indigenous knowledge. This implies that indigenous knowledge was one of the most significant issues affecting food security in Kilifi South Sub-county. To further enhance the understanding and improvement of food security status in Kilifi South sub-county, indigenous knowledge is necessary. This will help households make long-term investments in new agricultural innovations hence improved food production and food security levels. The stakeholders should educate the farmers in the study area about the right seeds to plant to cope with climate change.

The root rot disease of Solanum nigrum caused by Rhizoctonia bataticola is a serious fungal disease in Tamil Nadu. Yellowing of leaves, discolouration and rotting of roots and dark brown lesions on the stem are the prominent symptoms of root rot disease. The field experiments were conducted in the farmer’s field at Kaalipalayam, Coimbatore district, Tamil Nadu during 2015-2016 and 2016-2017 to find out the effect of fungicides and biocontrol agents for the management of root rot disease of S. nigrum. The results revealed that soil application of Trichoderma asperellum at 2.5 kg/ha mixed with neem cake at 250 kg/ha followed by seed treatment with T. asperellum at 4 g/kg seed was effective in managing the root rot disease and increased the leaf yield.

Background: The ancient practice of traditional bone setting dates back many centuries. In the developing world, the traditional bone setters are still patronized despite numerous limb and life-threatening complications that result from their treatment of limb injuries. Limb amputation in children resulting from bonesetter's gangrene is a common and a disturbing complication.  

Aim: To present six consecutive cases of extremity amputations in children resulting from bonesetters' gangrene.

Results:  Six consecutive extremity amputations resulting from bonesetters' gangrene were done at the study site from April 2013 to March 2016, constituting 8% of all limb amputations and 73% of all extremity amputations done in children within the same period. Five of the patients were males while one was female. Ages ranged from 18months to 17 years with a mean age of 10.2±13.3 years.  All amputations involved the upper limb. All patients visited the traditional Bone setters (TBS) with five of patients ‘admitted' in the Bone Setter's place for more than two weeks.

The treatment method was similar in all patients and involved the use a tight splint localized to the fracture site and intermittent massage using a local ointment. All patients had satisfactory wound healing and were discharged home not later than the 14th-day post surgery.  

Conclusion: Limb gangrene is one of the most regrettable complications following Traditional Bonesetters treatment of extremity injuries. With the poor rehabilitative function of amputated limbs and the high cost of the functional prosthesis in the sub-region, urgent steps are needed to prevent such complications in the sub-region.

In this study, the empirical effect of monetary policy tools on performance of the Nigerian capital market was re-examined. The real effect of monetary policy tools on capital market performance is still not clear both from theoretical and empirical background, especially in emerging economies like Nigeria. Explicitly, this study evaluated the effect of monetary policy rate (the rate at the Central Bank of Nigeria extend credit facility to other financial institutions operating in the country), cash reserve ratio, liquidity ratio and loan to deposit ratio on the performance of the Nigerian capital market. Nigerian Stock Exchange and Central Bank of Nigeria annual reports of various edition supplied the relevant data for analysis. The Autoregressive Distributive Lag (ARDL) was the technique applied in estimating the model and for co-integration assessment, while granger causality analysis aided in ascertaining the effect of monetary policy tools on capital market performance. The result of the analysis illustrated that monetary policy tools and capital market performance in Nigeria are not co-integrated. The study also found that Nigerian capital market performance is not significantly affected by monetary policy announcement by the Central Bank of Nigeria rather, it is monetary policy rate that is significantly influenced by performance of the capital market. Based on the application of a superior methodology by way of ARDL in data analysis, the Central Bank of Nigeria should be cautious and properly consider the prevailing macroeconomic condition in monetary policy decision, especially with regard to liquidity ratio because of its potential in fuelling or deterring inflation which affects prices of stocks in the capital market.
