Sickle cell disease is a major public health problem in Africa and many other areas across the world. In Senegal, a lot of plants are proposed by traditional healers to manage the sickle cell disease, among them Combretum glutinosum. Antisickling activity of Combretum glutinosum leaves extracts was studied in this work. Methanolic and ethyl acetate extracts of Combretum glutinosum leaves were evaluated on SS sickles type to determine their anti-sickling potential. Antiradical properties of methanolic extract were evaluated using the DPPH radical as oxidant. Total phenolic content of the methanol extract was determined. Phytochemical screening of the crude extract of methanol revealed the presence of tannins, saponins, phenols and flavonoids. Results show a good antisickling effect of extracts with a maximum antisickling revers of 81% and 69% respectively, of the methanol and ethyl acetate extracts at 10 mg/mL versus 67% for arginine at 120 min of incubation. The measured IC50 were 0.65 and 0.163 for respectively the methanol extract and ascorbic acid. Antiradical powers 0.155 and 0.62 respectively for methanol extract and ascorbic acid were calculated from the effective concentrations. The results of this study confirm the traditional use of Combretum glutinosum leaves in the management of sickle cell disease.

Interactive video conferencing through satellite is an effective means of transferring the latest technologies to farmers. A study on the effectiveness of interactive video conferencing with farmers through VRCs for agriculture information dissemination is very much important to decide a massive replication of this model of communication. The study was conducted at Karnataka state of India. Twenty farmers who frequently visited the VRCs were selected randomly from each VRC, thus constituting a sample size of 200. Personal Interview and case study method was used for data collection. From the personal variables, it is evident that VRC programmes attracted more of young (33.3%) and middle age groups (38%). Among the participants 63% were male. Irrespective of the educational qualification, all of them had participated in VRC programmes. It was observed that social participation was low for more than half of the respondents (54%) and 40 per cent of them had low cosmopoliteness. The case studies had revealed that farmers felt greater satisfaction as they could interact with the experts directly and could solve their problems, could save money and time, could find new enterprises that are profitable to them. Among the constraints the highly scored one was regarding the timing and duration of the programmes (69.5%). The prominent suggestions included regarding inculcation of experiences of progressive farmers and more success stories (89%). The study was ended with the conclusion that the technology transfer to farmers through this modern method of communication can empower the rural farmers in developing countries, enhance ecological and livelihood security and accelerate human development and quality of life.

The use of synthetic polymers (Plastics) has become part of our everyday life since their introduction over 100 years ago. Every vital section of the economy ranging from clothing, agriculture, packaging, automobile, medicine, electrical and electronics have been virtually revolutionized by application of plastics. The challenge of the disposal of these plastics after use is what this study seeks to address in part. Low density polyethylene (LDPE) and polyethylene terephthalate (PET) plastic wastes were blended with bitumen as binder for road construction as an effective and valuable means of disposing these wastes, employing marshall hot-mix design. 15% and 30% w/w LDPE and PET wastes of total binder required for the asphalt design were incorporated at 6% optimum binder content. The polymer modified asphalts (PMA) were tested for marshall stability and flow. At 15% w/w LDPE, the stability and flow values are 819 kg and 3.6 mm, respectively, while at 30% w/w LDPE, the stability and flow values are 643 kg and 4.1 mm, respectively. Similarly, at 15% w/w PET, the stability and flow values are 737 kg and 3.3 mm, respectively, while at 30% w/w PET, the stability and flow values are 707 kg and 3.5 mm, respectively. These results are in agreement with the “general specification for roads and bridges, vol. II (1997)” of the federal government of Nigeria, which specifies a minimum of 350 kg and 2-4 mm for stability and flow, respectively. However, the 15% LDPE and PET plastic wastes incorporation gives better results than that of the 30% incorporation.
