The valorization of crop residues could constitute an energy source (biogas) allowing to reduce the energy needs of populations in agricultural regions, improve their living conditions and slow down deforestation as well as greenhouse gas emissions. This work aims to determine the typology of agricultural waste in the departments of Soubré, Sassandra, Daloa and Issia, to determine the number of residues generated in these departments, and to assess the biogas potential of these departments said residues. Field observations were made to identify the different types of waste, then, based on agricultural statistical data from the Ministry of Agriculture and biogas productivity indexes, the quantities of agricultural residues and biogas were estimated. Agricultural residues consist of pods (50%), stalks (19%), cobs (3%), Straws (8%), stalks (2%), shells (9%), fibers (7%), husks (1%), and bunches (1%). In addition, these localities have 465266.3 t of pods, 173583.2 t of stalks, 84280.0 t of shells, 75,857 t of straws, 12,000 t of husks, 10,987 t of bunches and 6793.0 t of fibers. The departments of Soubré, Sassandra, Daloa and Issia contain a total potential energy of 235.87 × 106 m3 of biogas. However, this is unevenly distributed among the localities. The volume of biogas recorded is higher in the department of Soubré (74.91 × 106 m3) which is followed respectively by the departments of Daloa (62.27 × 106 m3), Issia (52.77 × 106 m3 and Sassandra (45.93 × 106 m3). The departments of Soubré, Sassandra, Daloa and Issia have a very large potential for the production of agricultural residues that may be of interest to economic operators for recovery in biogas production units.

Most long-distance migrating passerines that breed in Europe spend their winters in Africa,with only a few species migrating eastward to spend the non-breeding period in South *** use of the Indo-European flyway is rare and has been poorly studied so ***,it is extremely interesting as within that system we are currently witnessing a recent range expansion of European breeding long distance migrants and thus the lengthening of migration *** may therefore conceal a unique migratory strategies and behaviour that can help us to understand the underlying factors and mechanisms determining the evolution of migration routes,strategies and breeding range *** on light-level geolocator we reveal a first track of the Citrine Wagtail(Motacilla citreola)migration,providing insight into the migration pattern,timing and behaviour of the species that recently has extended its migration ***,the studied individual did not retrace a recent range expansion that runs north and east from the Caspian Sea but followed a migration route running south form the Caspian sea,suggesting possible presence of an alternative species range *** overall migration distance between the breeding site in Poland and the non-breeding site in Pakistan was about 10,420 km and included two endurance movement phases(920 and 2240 km)covering 30%of the whole journey length,with an average movement speed of 574 km/*** explain this migration behaviour as an adaptation for crossing the ecological barriers imposed by arid environments.

Background: Jaw cysts and cyst-like lesions cause facial deformity, destruction of dental tissues and affect masticatory and phonation functions. These ad-versely erode patients’ psycho-social status;create low self-esteem and may change one’s facial identity and appearance. Objective: To determine the histo-pathologic characteristics, variants and demographic pattern of jaw cysts and cyst-like lesions at the University of Nairobi Dental Hospital. Material and Me-thod: This was an analytical and verification study that involved microscopic re-examination of all available incisional/excisional biopsy samples from January 2000 to December 2009 for histo-pathological diagnosis at the University of Nairobi Dental Hospital. Results: 187 jaw cysts and cyst-like lesions were diagnosed at the University of Nairobi Dental Hospital over the ten-year period. Keratocystic odontogenic tumours constituted 28%, dentigerous cysts 25%, nasopalatine duct cysts 19%, radicular cysts 15%, while calcifying odontogenic cysts comprised 4% of all the lesions. The rest of the lesions were between 1% and 3% of all the lesion entities. Conclusion: Keratocystic odontogenic tumours and dentigerous cysts were the most common developmental odontogenic cysts diagnosed in the ten-year period.
