This scientific publishing consisted to evoluate the relationship between chemical structure and pharmacological activities of an antipaludical plant “Hygrophilla auriculata ”. The process consisted to a thin layer chromatography using two standards moderns’ drugs with are usually used to treat paludism. Final results revealed factor retention (Rf) similar of quinine sulfate and another equal to the Rf of “L-artem forte”. This result leaded us to conclud that there are similarities in chemical structure of some active ingredient of Hygrophilla auriculata and the modern anticipaludical drugs.
In the relict forest shreds located in Ituri in the territory of Djugu, on the shores of Lake Albert in the Democratic Republic of the Congo (DRC), a preliminary study on herpetofauna was carried out. According to this research, 19 amphibian species and 21 reptile species were harvested in 12 days between April and May 2017. Samples were taken from four research sites: Dzu (N01.94753°; E030.88848°), Dzoo (N01.92742°; E030.89179°), Nzerku 3 (N01.94119°; E030.90612°) and Nzonzo (N01.90352°; E30.91030°). The principal objective of this study was to inventory the herpetological fauna of the Relict Altitude Forest of the Albert Lake Escarpment (RAFALE) landscape. During the night, amphibians were captured by hand by using headlight. A herpetological stick was used to collect reptiles. These biopsies consisted essentially of tissue from the tongue and muscle. Specimens were photographed alive then fixed with formalin (10%), before being preserved in alcohol (70%). Results are interesting and show that the habitats are very rich and diversified. There were more diverse reptiles than amphibians. Considered as a 'red area' where studies are known to be hostile, through this research, it is appropriate to point out that the potential for further in-depth research and focusing efforts for the sustainable conservation of this area is both possible and still urgent.
Studies have shown that the flow dynamic of water in aquifer is very complex and it is difficult to observe or characterize directly the processes that occur in the porous media of the soil structure. As a result of this, carrying out studies on the characteristics of contaminants at the subsurface often relies on indirect measurements of the parameters of the system. However, the continuous use of tracers in simulation studies to model hydrological characteristics at the subsurface have provided an important tool for understanding the flow and mixing dynamics of water resource systems. Result obtain from this tracer test shows that multidimensional transport in an aquifer involves both longitudinal and transverse dispersion in addition to advection and can be achieved using a radial flow test. Transverse dispersion in an aquifer can spread dissolved contaminant faster than advection by molecular diffusion when flow velocity of groundwater is highly low. The initial concentration of dissolved contaminants at a source point can cause an upstream spreading by molecular dispersion in an aquifer. The use of tracer test can provide preliminary information for site characterization and groundwater monitoring to help in the design of environmental network to evaluate possible accidental migration of contaminants once it occurs in aquifers and plan suitable mitigation actions to safeguard our water resources.
This scientific article had as objective to compare the antipaludic activities and efficiency of Hygrophilla auriculata plant than those of antipaludic modern drugs.
The method consisted to mixture samples of strongly infested blood with Hygrophilla auriculata extracts in some samples and modern anti-malaric dugs in others. After incubation of 24h, 48h and 72h we passed to the parasitologic test.
Obtained result revealed the high efficiency and antimalaric activities of Hygrophilla auriculata crudes extracts than modern anti-malaric drugs such as Quinine and “L-Artem Forte”. This leaded us to conclude that Hygrophilla auriculata plant has a hight antipaludic activity so it must be used to treat people great leak region.
An inventory of amphibians and reptiles had been carried out in the Ituri forest and Mutwanga. The herpetofauna of this region has never been the subject of a recent study. In order to analyze its biodiversity, 4 remote sites of each other, all located in the primary forest had been sampled. The collection of data had been carried out during the dry season from December 25, 2014 to January 12, 2015 (18 days). The prospecting of sites took place during the day and the night. In total, 182 specimens of amphibians divided into 32 species, 4 families, all belonging to the Order of the anurans and 37 specimens of reptiles diversified in 18 species, 7 families and grouped in two Orders had been inventoried. The capture of the species: Hymenochirus boulengeri, Hyperolius rossii, Amietia desaegeri, Amietia ruwenzorica, Xenopus lenduensis and Xenopus ruwenzoriensis were interesting, because these species are poorly documented in the region.
The promotion of praxeological law leads us to conclude that the current military judicial code and the military penal code, instituted by two successive laws 023 and 024 of November 18, 2002 are characterized by a rigor inherited from the decree of December 22, 1888 of the colonial legislator establishing the military courts. This explains the "symbolic traps" within these codes, hence the urgent need for their reform so that the Congolese military justice is humanized and conform to the social experience, the socio-military praxis.
It must be said that there is need for the development of the praxeological military judicial law, capable of detecting "symbolic traps" in the various texts and codes that characterize the current military judiciary, and which will be the most effective response the problem of the humanization of military justice, particularly the abolition of military jurisdiction in peacetime, as in the Belgian and French legislation that constitute the bedrock of Congolese law.
What is the place of the displaced victims of Boko Haram in the society of Diffa? This research question is supported by the hypothesis that the conflict engendered by Boko Harem is fueling poverty in the Diffa region. The main objective of this study is to demonstrate the level of assistance provided by humanitarian workers to the displaced. The study was conducted following a field survey in the accommodation sites of the victims of the conflict. The results of the study reveal that the conflict has left the displaced in an emergency situation and requires the participation of all.
The coastal environments are highly coveted for their tourist and economic interests and constitute fragile ecosystems, sensitive to human’s actions: Pollution, artificialization, drying up, industrialization, urbanization, etc. shipbuilding has often contributed to aggravating the phenomena of erosion and retreat of coastlines. The heightening of coastal of Lake Kivu creates many pressures, particularly in the south basin. This southern basin of Lake Kivu is coveted by housing, hotels and churches, and is at the crossroads of commercial activities that alter them more and more. Out of a total of 19.14km of study, the occupied area is 11.07km with a high concentration of dwellings between the National Coffee Office (Bagira) and LABAOTE (see map). All these anthropogenic actions are source of pollution and destruction of the ecosystem of Lake Kivu in general and its littoral in particular. To remedy this, this article proposes to start the sectoral relocation of the occupants of the southern basin of Lake Kivu. Failing this, transitional strategies consisting of setting up a waste management network, delimiting the public domain, etc. are recommended for this purpose.
States in the South are no longer able to fulfill their redistributive function, that is to say to provide for the socio-economic needs of their population. In this context, the rural and urban populations of these countries are obliged to develop new forms of solidarity and mutual assistance in order to find solutions to the problems they are confronted with. Although the use of this notion is recent as elsewhere in Francophone Africa, it nevertheless relies on the organization of inherited practices of volunteering and adherence to collective work very old
Twenty years ago, the Kabare chiefdom developed savings and credit groups on the model of solidarity mutual. Farmers are grouped either according to the environment, the affinities and according to their activities are fixed an amount, the deadlines and the beneficiaries by rotation. Designed to provide basic financial services to their members, these endogenous initiatives operate in the informal sector and receive no external input in terms of funding and training. In addition, the difficulties of appropriation of these decentralized financing structures by the members constitute the blockages in the evolution and the perpetuation of the financial services. Added to this, the low membership rate of the members, the low contribution rate of low household income, the poor organization due to lack of expertise, the proliferation of savings and credit institutions, the overlap and competition caused by the current diversification of Village Savings and Loan Association.
Medicinal plants are abundant in Myanmar. In the present research, the root of Stemona curtisii Hook. F. was chosen for investigation of some phytochemical constituents and bioactivity studies. Acute toxicity of 95 % ethanol extract from roots sample was investigated by methods of OECD guidelines for the testing of Chemical 425. Screening of root extract was done with the dosage of 2000 mg/kg, 300 mg/kg and 50 mg/kg body weight in albino mice. Antimicrobial activity of pet- ether, methanol, ethyl acetate, 95 % ethanol and watery extracts from roots of S. curtisii was investigated against six species of microorganisms such as Bacillus pumilus, Bacillus subtilis, Candida albicans, Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus species by agar well diffusion method. Among them, ethyl acetate and methanol extracts of S. curtisii exhibited inhibition zone diameter in the ranges of (12 15 mm) and (11 20 mm) against all tested microorganisms. According to the results, it can be inferred that root of S. cutrisii may be used as remedy for the treatment of diseases related to the microorganisms tested.
This research intends to present, analyze and forward a view on the socio-economic impact of paid transport of people by small bus in Bukavu city. The results of this study will enable the public authorities to set up appropriate structures, mechanisms and supervisory measures for this sector, thus guaranteeing healthy social and economic conditions for the population. The main question of our study is: “What is the social and economic profitability of the actors in the transport of people on small bus? We emitted a hypothesis according to which all the actors would get some income, reason why the sector becomes more and attractive. However, the growth of the sector would create other ill-effects. To check the hypothesis, we used both quantitative and analytical methods. This study was carried out in Bukavu city on small bus owners and the population who use this mode of transport. At this end of the study, we come to the conclusion that paid transport of people in small bus has a social and economic impact in Bukavu city, mainly on the social life of motorcyclist, the income of small bus owners, public transport of population and the public receipts. The ill-effects of the growth of this sector is the increase of traffic accidents, the emergence of professional illnesses (paralysis, bronchitis …) and the decrease of school children numbers.
This article laid down the objective to identify the characteristics of the teacher in function of which the performances of the schoolboys out of skills life differ significantly. Based on the demographic characteristics, the qualifications, the experiment of the teacher and the composition of the class, this study led to the results hereafter:
Two characteristics of the demographic background of the teacher proved significantly acting on the performances of the schoolboys: the sex and the age of the teacher. In the teacher’s background of the qualifications, it is the percentage carried out with the state examinations which proved to be significant contrary but not the studies’ level.
For the experiment of the teacher, all the variables retained for this study had an effect on the performances of the schoolboys: duration of the diploma, seniority in teaching, at the school and in the class and recycling. Let us note nevertheless that recycling showed a contrary effect rather.
Concerning the composition of the class, a significant effect was found to the number of pupils and the percentage of the girls in the class. About these results, certainly, the teacher’s characteristics constitute a substantial component in the education quality sought so much by all. However, it will not be rational to consider the significant variables here proven without taking account of the context, the medium and the moment in which evolves/moves an education system and especially of the effects of the analyses differentiating the "teacher’s characteristics" from the «educational practices".
