The aim of the present work is to develop a new model to assess the Corporate Social Responsibility CSR performance of an organization based on a holistic and interdependent approach as described in the foundations and principles of the ISO 26000 standard. The proposed model generates a new Corporate Social Responsibility (CSR) Index, which help the organization to characterize and assess its performance regarding to the seven core subjects of ISO 26000 standard, with the different stakeholders. Inspired by the work of G. K. Kanji and P. K. Chopra, we propose a model of structural equations composed of latent and manifest variables. The model identifies the various connections between the different components (the core subjects). The implementation on the XLSTAT software provides an index for each latent variable that can be analysed in order to improve the CSR performance.
The present study was carried out from 346 skulls of Praomys jacksoni (Muridae) captured in some forest areas of the surroundings of Kisangani city (island, right and left banks of Congo River) from 1994 to 1999). The results obtained from twenty-five skulls measurements revealed the diversity existing inside each population studied. The sexual dimorphism is favorable to males for seven measurements (GRLE, HEBA, DIA1, DIA2, INT, LNAS, and LOTE) whereas eighteen remain stable. The skulls of insular populations (Tundulu and Mbiye) are bigger than those of the forest reserves ( Masako and Yoko) for twenty measurements: GRLE, PRCO, HEBA, HEPA, DIA1, DIA2, INT, ZYPL, PAL, UPTE, UPDE, M1, BNAS, LNAS, BUL, DIN, HRZ, ROH, ROB and PCPA The skulls of Mbiye island populations are bigger than those of Tundulu island for eighteen measurements (GRLE, PRCO, HEBA, HEPA, PAF, DIA1, DIA2, ZYG, UPTE, UPDE, M1, ZYPL, BNAS, LNAS, LOTE, CHOA, DIN, PCPA). The skulls of populations from the left bank (Yoko forest reserve) are bigger than those of the right bank for six measures (GRLE, HEBA, DIA1, INT, CHOA and PAF). These results indicate that craniometrical measurements of the adult animals are stable and constitute a complementary means for identifying the species in the Praomys genus. The variations observed with certain examined characters would be the consequence of the biological phenomenon of speciation. It is thus desirable that molecular studies are carried out on these muridae in order to validate this hypothesis.
All activity constitutes a work of the knowledge. This one, according to bachelardian vision, clears itself from a discussion between acquirements of the science and the convenient problems. This gait remains inescapable for the societies development and for the case of species, the province of Sud-Kivu, where we made the state of places of various centers of research.
According to local nomenclature, there are four sub lagoons that represent the lagoon system of Grand-Lahou. The Tagba lagoon is the most important one because it is in contact with the sea through the mouth of Bandama river. The Morphology and the bathymetry constitute a challenge for local residents whose main activity is fishing. The present study aimed to update the bathymetry of the lagoon. The depths obtained are low, 3 m on average with maximum of 6 meters. The action of river currents and tidal current is responsible of the morphology of channels.
La RDC est depuis plusieurs décennies confrontée à multiples problèmes liés à la corruption dans tous les secteurs de la vie sociale. La corruption en RDC, n’est plus le fait de la simple conjoncture et donc une des stratégies de survie, un fait isolé ou abus singulier mais une structure, un dispositif ou une bureaucratie du gain facile qu’il importe de mettre à jour.
Nous voulons contribuer à la compréhension du niveau de criminalisation et de l’indice de perception de la corruption dans l’Administration publique et privée à Bukavu. Plusieurs mobiles mis en exergue du fait que cette étude fait preuve de l’existence des plusieurs pratiques corruptionnelles vécues dans l’Administration publique à Bukavu. Dans cette dernière, plusieurs formes de corruption s’étoffent et tendent à favoriser une catégorie des couches sociales au détriment d’une autre. Scientifiquement, cette étude étoffe des nouvelles connaissances en rapport avec la compréhension de la corruption. Socialement cette recherche est un outil de conscientisation des gouvernants, des gouvernés pour le développement de la RD Congo. Pratiquement, la conscience professionnelle nait de cette recherche et assure les générations futures. Des questions relatives au problème posé : Comment comprendre les manifestations, les causes, les conséquences de la corruption dans l’administration publique à Bukavu ? Comment prévenir la corruption dans l’administration publique, comment la combattre, la réprimer et quels en sont les mécanismes d’éradication progressive ? Quelles pistes de solutions préconiser pour que la gestion de la corruption soit efficace ?

The environment is a key factor in the quality of life. If it is precarious, it will undermine it.
The uncontrolled construction in the city of Bukavu and particularly in the area Cimpunda has negative consequences on the environment and on humans. The first (environment) suffers upheavals, sometimes irreversible, followed by the imbalance of ecosystems related to uncontrolled building on unsuitable sites the second (man) suffers from deterioration of quality of life due to the lack of sewerage and other infrastructure, the water supply insufficient or garbage collection services.
The Cimpunda district, with an average altitude of 1569m, experienced and still been growing, unprecedented, its population through time from 35000habitants in 2010 to 45000 in 2015; a situation following a high birth rate, death rate declining and the rural exodus. This population growth without spatial growth, has led to negative consequences, among other anarchic constructions which do not leave intact the environment in the suburban areas of the city of Bukavu: overextension of the population, floods unhealthy, the loss of green areas and other ecosystems.
Diagnostic realized in this work thus sets in parallel the induced effects of uncontrolled construction and destruction of the environment in this popular area of the city of Bukavu.
This investigation aimed to test the response of female after injection of pituitary extracts collected from the male of Clarias gariepinus and the nutritional effect of two diets that one from animal proteins (diet A) and another from vegetable proteins (diet B) on survival and growth of larvae from the induced reproduction.
During 21 days, the larvae were fed with these two diets containing 40% of protein, 11.61 Kj.g-1 and 12.71 Kj.g-1 of energy respectively for diets A and B in order to know the effects on survival and growth of juveniles. The findings showed that the induced reproduction used for this work is interesting as to the response of female to injection of the pituitary extracts (100%) and to hatching rate from aquatic plants used as support (hyacinths). Furthermore, the results showed that the food used from local products is acceptable for the growth of larvae from their first age. On the other hand it appears that there’s no significant difference between these two diets (A and B) although the diet A from animal proteins appears as the best compared to diet B from vegetable proteins.
A study on the toxic and nutritional values of four wild vegetables (Ipomoea aquatica, Dewevrea bilabiata, Vitex welwitschii and Vernonia hochstetteri) was performed before and after cooking. In this study, it appears that these wild vegetables can be dietary supplements of values in those for crude protein, fat, calcium, magnesium, iron, phosphorus and vitamins (A, B1, B2, B6 and C). The leaves of Ipomoea aquatica are particularly rich in lipids (21 gr/100 gr), vitamin B2 (0.38 mg %), vitamin C (0.2 mg%). The Dewevrea bilabiata leaves are rich in crude protein (0.04 mg/100g r), vitamin B2 (0.38 mg%), vitamin B6 (0.8 mg%), vitamin C (0.2 mg%) and leaves of Vitex welwitschii rich in vitamin A (0.75 mg/100 gr), vitamin B1 (1.33 mg/100 gr), vitamin C (0.2 mg%). However, these vegetables also contain some undesirable substances including alkaloids, tannins, flavonoids, sterols and terpenes, traces of toxic substances such as cyanide and nitrites before cooking. After cooking, these substances and toxic components disappear. Similarly, cooking significantly reduced the levels of different nutrients. All these results justify the use of these plants in the diet of the population living around Kisangani city. A cooking these vegetables at moderate temperatures is recommended.
The polypropylene copolymer (PPR) is a thermoplastic material widely used to transport hot and cold water under pressure. In operation, PPR pipes are sometimes subjected to accidental damages that may cause a reduction in residual resistance or even a complete fracture of the structure. Hence the need to characterize the behavior of virgin and defective PPR pipes under pressure to develop carefully a maintenance strategy to ensure a minimum cost with the maximum reliability. In this article and according to ASTM D1599, we conducted a set of real tests of bursting on virgin and notched pipes to assess the level of damage reaches mechanically and characterize the behavior pipes in PPR pipes. The experimental results allowed and identification of the three stages of development of damage namely: initiation, progression and sudden acceleration. The estimation of the damage degree by the model of static damage led to identify theoretically the three stages of the evolution of damage. Subsequently, a theoretical reassessment of the damage level was done through a judicious adaptation of the theoretical model proposed in unified theory of damage. Theoretical and experimental results showed a good agreement.
The theme of this article is "Comparative Production of ethanol through fermentation of a few natural sources of sugar Province of South Kivu." The high price of ethanol to the market making it unreachable product to the people dictated the choice of this theme. This work covered a period from December 2015 to February 2016 in the province of South Kivu.
This was done methodologically by fermentation of different sources of sugar including pineapple, sugar cane, sorghum and sweet potato leaves. Fermentation was followed by distillation to find concentrated alcohol.
It was noted that in addition to ethanol, the pineapple juice was too overloaded with other products (10.1% distillate / distillate volume) while the sweet potato leaves turn out to be the most appropriate ( 5.5% of distillate / distillate volume). Moreover, the sugarcane produced a better yield in alcohol (47.1%) while the sweet potato leaves produced in low percentage (15.2%).
