A coding scheme for OFDM transmission is proposed, exploiting a connection between pairs of Golay complementary sequences and second-order Reed-Muller codes. Using a realization of 16-QAM or 64 QAM constellation as the vector sum or two or three QPSK constellation respectively we construct 16 QAM and 64 QAM sequences having low PAPR. In this paper, we further examine the squared Euclidean distance of these M-QAM sequences and their variations. Our aim here is to combine the block coded modulation (BCM) and Golay complementary sequences to trade off the PAPR, the code rate, and the squared Euclidean distance of M-QAM OFDM signals

This study examined the effect of crude oil price on agricultural productivity in Nigeria between 1981 and 2010. Agricultural productivity (proxy as agricultural GDP) was specified as a function of factors such as exchange rate, crude oil price, capital stock, labour, land and fertilizer. Quantitative estimates, based on Augmented-Dickey Fuller (ADF) unit root test, Co-integration and Error Correction modelling, indicate that the exchange rate, capital, labour and trend are the major determinants of agricultural productivity in the long-run, while price of crude oil price is the most important determinant of agricultural productivity in the short–run. The results further shows that the error correction mechanism (ECM) indicated a feedback of about 112.5% of the previous year’s disequilibrium from long-run domestic agricultural production.

Business practices in Somalia have gone through many innovations. One of the most dynamic of these innovations has been mobile money. Different telecom companies provide different brands of mobile money. However, amongst EVC plus offered by Hormuud telecom is the most popular mobile money that people depend on their daily transactions in south and central Somalia. However, without effective functioning of central bank, limited education of business owners, unfavorable domestic environment, lack of business information; wide spread of mobile money adaptation by SMEs is likely to affect their financial performance. However the study sought to investigate the effects of mobile transfer on the financial performance of Small and Medium Enterprises (SMEs) in Mogadishu, Somalia. More specifically, the study sought to achieve the following objectives; to assess the extent to which mobile money transaction cost, number of mobile money transactions, financial literacy and mobile money transfer regulations affect the financial performance of SMEs in Mogadishu, Somalia. The study adopted a descriptive survey method which was conducted through administration of questionnaires. Data was collected from a sample of 146 SMEs in Bakara market using purposive sampling technique. Both descriptive and inferential statistics were then used to analyze data with the help of statistical package for social sciences (SPSS) version 21.0.The results of this study revealed that there was a relationship between mobile money transfer and financial performance of small and medium enterprises. On the basis of the findings of this study, it was concluded that mobile money transfer had positive effect on financial performance of small and medium enterprises. The study found that mobile money transaction costs, financial literacy and mobile transfer regulation, affected financial performance of small and medium enterprises. It was recommended that due to the effect of financial literacy and mobile transfer regulation, managers should ensure they build capacity in terms of financial knowledge and also liaise with the regulator on the various regulations to be adopted. It is suggested that the Central Bank of Somalia needs to come up with a complex regulatory framework on how mobile platforms can transact effectively in the financial system. The Central Bank of Somalia needs to build capacity amongst its employees so as to be prepared for mobile innovations especially where money transfers are involved.

This study was conducted with a view to identify the socio-economic characteristics of processors of Vitellaria paradoxa and Parkia biglobosa; to examine the role of the rural dwellers in the sourcing and processing of V. paradoxa and P. biglobosa; to examine the different benefits that accrue to commercial processing of V. paradoxa and P. biglobosa and to investigate strategies put in place for sustainable use of V. paradoxa and P. biglobosa in the study area. Three (3) Local Government Areas were purposively selected for the study and purposive random sampling method was adopted for the selection of respondents. Primary data were obtained through the use of questionnaires while secondary data was gathered from relevant literature. Data collected were analyzed using descriptive statistical tools and gross margin analysis. The result showed that 90% of Vitellaria paradoxa and 94.3% of Parkia biglobosa processors were female. Majority of the processors of V. paradoxa (77.1%) and P. biglobosa (58%) fell within the age range of 21-40 years. Fruits of V. paradoxa (84.3%) and seeds of P. biglobosa (77.1%) were obtained from processors farmlands as a result of the relative availability of the trees on their farmlands. The remaining processors of V. paradoxa (15.7%) and P. biglobosa (22.9%) had no trees on their farmlands so they gathered the fruits and seeds from and around forest lands. 84.37% of V. paradoxa and 88.5% of P. biglobosa processors indicated that income was the main economic benefit derived from this business while social benefits highlighted by the respondents ranged from produce been used as food, medicine, condiment and cosmetic. The result also showed that processors of V. paradoxa incurred more costs, produced more output and had a higher average gross return in processing than P. biglobosa processors. The RORI for the processing business in the study area was 51% and 96%. To promote sustainability the people have adopted local means of sustaining production by preventing indiscriminate livestock grazing and bush burning.

The aim of the present study was to evaluate the efficacy of application of chlorhexidine mouthwash on Candida colonization in patients with complete dentures. Sixty-eight patients with complete denture were included in this study and divided in two groups. One group of patients were instructed to rinse their mouth with chlorhexidine mouthwash once per day for one week. The second group of patients were instructed to use placebo mouthwash containing normal saline solution. Palatal swabs and smears were taken from each patient before and after chlorhexidine and saline application and specimens were examined mycologically. For each group, Candida colony forming units (CFU) were assessed using Sabouraud agar culture. The difference between Candida colonization before and after treatment and the differences between pre-treatment and post-treatment clinical findings were assessed using paired t test. Application of chlorhexidine mouthwash significantly reduced the CFU and improved the palatal inflammation (p<0.05). This reduction was found in all patients even in smokers and diabetic patients, as well as in the subjects without suitable denture health. We demonstrated the effectiveness of application of a commercial chlorhexidine gluconate mouthwash in the management of candida colonization in patients with complete dentures specially in high-risk candidates.
