Local knowledge, pattern and diversity of use of Sclerocarya birrea
Gerard N Gouwakinnou, Anne Lykke, Achille E Assogbadjo, Brice Sinsin
Journal of Ethnobiology and Ethnomedicine , 2011, DOI: 10.1186/1746-4269-7-8
Abstract: This study combines quantitative and qualitative ethnobotanical approaches to investigate uses and factors affecting the use value of S. birrea subsp. birrea. Nine group discussions as well as 161 individual interviews were held in the dry and typical Sudanian zones. Seven different ethnic groups were involved and the survey focused on local uses and perception of factors affecting the dynamics of S. birrea.The species has a multitude of uses; all organs are used for more than 20 different purposes. The study highlights how gender, local availability, ethnicity and community location interact to influence the utilization value of the species. People living in drier areas with high occurrence of the S. birrea use it more than those living in wetter areas with low occurrence. While domestic and subsistence uses do not appear to threaten the species, carving, clearing and drought stand out as the major causes of its decline.Many factors and their interactions influence the use pattern of the species within and between communities. When compared to the level of exploitation of S. birrea subsp. caffra in southern Africa, the subspecies birrea is at this point relatively underutilized. A high commercial potential exists due to its simple propagation ability and makes it an interesting agroforestry resource.Growing interest is on food tree species in general, and particularly indigenous fruit tree species in developing countries since they are inherent to most tropical landscapes and serve the dual function of local livelihood support and biodiversity conservation [1]. More information on these trees would enhance their value in agricultural landscapes by helping farmers improve their livelihoods and ensuring environmental sustainability. Therefore, there is a need to settle a general framework for the conservation of these tree species.Understanding how a community uses a resource and what influences the level of its use is crucial for developing a framework for its susta

Journal of Ethnobiology and Ethnomedicine , 2011, DOI: 10.1186/1746-4269-7-42
Abstract: From 13 ethnic groups, 1587 people were interviewed in the study area using semi-structured questionnaires. Principal Component Analysis was applied to analyze the use value and the use patterns of P. biglobosa for the different ethnic groups.All interviewees in the study area knew at least one use of P. biglobosa. The various uses identified were medicinal (47%), handicraft and domestic (3%), medico-magic (1%), veterinary (1%), cultural (1%), food (25%) and commercial (22%). The various parts involved in these types of uses were: fruits [shell (2%), pulp (22%) and seeds (36%)], bark (17%), leaves (9%), roots (3%), flowers (1%) and branches (10%). The ethnic group consensus values for P. biglobosa parts showed that the seeds are used the most. The interviewees diversity value (ID) and equitability value (IE) indicated that knowledge concerning P. biglobosa use was distributed homogeneously among the ethnic groups.P. biglobosa is well-known and used in different ways by the local populations in the study area. Local knowledge on the species is diversified and influenced by ethnic group. Ethnic differences in use values and use patterns of the species were evident in this study.In the Sahelian and Sudanian zones of West Africa, woody perennial parklands are very important for food security, especially during food shortage and drought periods [1]. Within these parkland systems, Parkia biglobosa species has important socio-economic and cultural values for local people. Moreover, it is a food species whose importance is well recognized both regionally and internationally [2]. In Benin, P. biglobosa is an important tree species which generates non-timber forest products [3,4]. It is a basic and therapeutic food and is a source of wealth [5]. The pulp of the fruit pods is rich in sucrose and the seeds are rich in carbohydrates, proteins and lipids, thus constituting an important source of energy [6]. P. biglobosa is rated fifth important among thirty-one woody medicinal pl

QScience Connect , 2013, DOI: 10.5339/connect.2013.12
Abstract: Medicinal plants play an important role in human livelihoods. However, the harvest of different organs may be destructive. Sarcocephalus latifolius is a species whose roots are harvested for medicinal purposes. This study was carried out to assess the root characteristics, biomass yield and morphological variations within different habitats of southern Benin. Forty-eight S. latifolius individual plants were randomly selected in three localities, representing four habitats for the species. Information collected was related to height, basal diameter, diameter at breast height, number, depth of insertion and the length and the diameter of the roots. Observations were also made on organ characteristics to identify morphologic variation. The study showed that the optimum development of the root system is established in fallow ground and savannas. The species presents two morphotypes at the stem and root levels. Root biomass varied according to the developmental stage and habitat. A model of root biomass estimation was established and can be used to determine the root biomass within habitats. Across habitat, the number of roots is the major determinant for root biomass yield. Therefore, harvest should take into consideration habitat and the developmental stage according to the use type.

Notulae Botanicae Horti Agrobotanici Cluj-Napoca , 2010,
Abstract: The present study occurred in the three climatic zones of Benin (6°25 - 12° N) and aimed at investigating the level of morphometric and genetic variation and spatial genetic structure within and between threatened baobab populations. A total of 137 individuals from six populations were analysed using morphometric data as well as molecular marker data generated with the AFLP technique. Five primer pairs resulted in a total of 217 scored bands with 78.34% of them being polymorphic. A two-level AMOVA revealed 82.37% of the total variation within populations and 17.63% among populations (P<0.001). Analysis of population structure with allele-frequency based F-statistics revealed a global FST of 0.127±0.072 (P<0.001). The mean gene diversity within populations (Hw) and the average gene diversity among populations (Hb) were estimated at 0.309±0.000 and 0.045±0.072, respectively. Baobabs in the Sudanian and Sudan-Guinean zones of Benin were short and produced the highest yields of pulp, seeds and kernels in contrast to the ones in the Guinean zone. The molecular results indicate some degree of physical isolation of the populations collected in the different climatic zones. We also found morphological differences but further analysis must be done to establish their origin which is certainly an interaction between genotype and environment. Sampling options of the natural populations are suggested for in or ex situ conservation.

Advances in Breast Cancer Research (ABCR) , 2015, DOI: 10.4236/abcr.2015.42005
Abstract:

This study aimed to estimate the survival rate of breast cancer in a group of patients followed up at the Yaoundé General Hospital in Cameroon. A retrospective review of records of patients managed for breast cancer between 1995 and 2007 was carried out at the Yaoundé General Hospital. Survival analysis was carried out with survival defined as the time between the date of unequivocal diagnosis of cancer and the date of last follow-up or death. Survival curves were plotted in R.3.1.1 software. Mean age of the patients was 47.5 ± 12.36 years. Most of the patients (67.9%) presented with advanced breast cancer disease (stage III and IV). Overall patient survival rate was 30% at 5 years and 13.2% at 10 years. Median overall survival time was 2 (1.9 - 3) years. There was a correlation between survival and the stage of disease. The highest survival rates were recorded in stages I and II while the lowest rates were recorded in stage IV. There was no statistically significant difference in survival among the age groups (p = 0.15). Overall survival rates of breast cancer are 30% at 5 years and 13.2% at 10 years among Cameroonian patients and are lower compared with 90% and 82% respectively at 5 years and 10 years in some developed countries.

As formas africanas de auto-inscri??o
Mbembe, Achille;
Estudos Afro-Asiáticos , 2001, DOI: 10.1590/S0101-546X2001000100007
Abstract: the objective of this paper is to analyze and criticize the different endeavors to build and display african identity, basically starting with a chauvinist discussion on one hand, and an instrumental one on the other, on africa and its people. based on a critical interpretation of the various essential points made regarding a supposed consensual world pan-african survey, the author warns against the perils originating from a thoughtless search of an african alterity without duly acknowledging african cultural, political and geographical specifics. both the economicism and the metaphysics of the difference are historicisms seen by the author as doomed to fail, considering the plurality of signs and contexts on which african self-registration and self-affirmation were based throughout the 20th century.
L'esecuzione processuale indiretta nella riforma del "Codice di procedura civile" italiano dal 2009
Saletti,Achille;
Revista de derecho (Valparaíso) , 2010, DOI: 10.4067/S0718-68512010000100015
Abstract: this article explains the recent modification the italian codice di procedura civil underwent that includes radical changes in the civil execution of judgement and also includes the "penalty payments" or pecuniary coercive measure for the benefit of the counterparty. this stipulation is part of the regulation of obligations to undertake infungibles or not undertake them, but does not limit its application to other types of obligation.

Achille Casale
ZooKeys , 2011, DOI: 10.3897/zookeys.100.1522
Abstract: Calleida desenderi Casale, sp. n., is described from Ecuador, Napo Province, surroundings of San Rafael. The new taxon is mostly characterized by the head and appendages rufous, the disc of elytra with marked metallic green reflection, the median lobe of aedeagus ring-like, and the endophallus with a long, twisted flagellum. A key for identification of the closer Neotropical species described so far is also provided.
Exact clesed form of the return probability on the Bethe lattice
Achille Giacometti
Physics , 1994, DOI: 10.1088/0305-4470/28/1/003
Abstract: An exact closed form solution for the return probability of a random walk on the Bethe lattice is given. The long-time asymptotic form confirms a previously known expression. It is however shown that this exact result reduces to the proper expression when the Bethe lattice degenerates on a line, unlike the asymptotic result which is singular. This is shown to be an artefact of the asymptotic expansion. The density of states is also calculated.
