Citrus senensis peel has many medicinal properties and is widely used against various ailments, such as colic, upset stomach, cancer, diuretic, cormunative, immuno – enhancing, stomachic, tonic to digestive system, immune system and skin. It is also used to treat and prevent vitamin deficiencies, colds, flu, and scurvy and helping to fight viral and bacterial infections. The aim of the study is to verify the ethnomedicinal use of the peel as anti-bacterial. The peels were air-dried and ground to powder using mortar and pestle, extracted with 95% ethanol. The extract was subjected to phytochemical screening using standard procedures. Agar diffusion method was employed to test the antibacterial activity of the extract and the MIC and MBC of the extract were determined by broth dilution technique. The results of the phytochemical screening indicated the presence of flavonoids, alkaloids, saponins, tannins, triterpenoids, phytosterols and steroids. The results of the antibacterial activity showed that the isolates were sensitive to the extract, with MIC of 0.25-2.5mg/ml and MBC of 0.5-5.0mg/ml. The antibacterial effects of the extracts suggest their possible use for the treatment of infections caused by the test bacteria. The chemotherapeutic potential of the fruit peel could be due to the presence of flavonoids, alkaloids, saponins, tannins, triterpenoids, phytosterols and steroids. The success of this study could lead to the development of cheap, easily available and relatively safe bactericides from a tropical plant.

The new configuration productive do not consider any more the space as a source of costs and as a passive support of productive factors but, it replaces it by the concept of territory, where its organization, its socio-economic and institutional characteristics, play an active role. This article aims to verify the hypothesis which assumes that the territory is a windfall for the productivity of the agglomerated companies. Indeed, by application to the Local Productive System (LPS) of Ksar-Hellal, it turned out that the specific resources of the territory can be in the service of agglomerated companies, but it is not necessary that they participate together in their productive efficiency, and in the institution of an endogenous dynamics of development. In addition, the analysis proved that social relationships play an unimportant role in the productive performances of the concentrated companies, putting into question the theoretical hypotheses, which consider the relevance of the role of the extraeconomic processes. Therefore, the assumption that all the specific resources of the country are responsible for the productivity of agglomerated firms should be allowed with some caution. There is no guarantee that the concentrated companies of LPS enjoy all the economic and social benefits of their territorial base. The agglomerated companies can take profit by exploiting their economic factors, while ignoring the informal aspects.

A Production-Distribution inventory model with shortages and unit cost dependent demand has been formulated along with possible constraints. In most of the real world situations, the cost parameters are imprecise in nature. Hence, the unit cost is imposed here in fuzzy environment. Due to complexity, the proposed model has been solved by LINGO software. The model is also solved for without shortages as the special case. The model is illustrated with a numerical example.

The screening and study of five different plant specimens belonging to different families for phytochemical constituents was performed using generally accepted laboratory technique for qualitative determinations. The constituents screened were saponins, combined anthraquinones, terpenoids, flavonoids, carotenoids, steroids, xantho proteins, couramins, alkaloids, quinones, vitamin C. The distribution of these constituents in the plant specimens were assessed and compared. The medicinal plant studied were Acalypha indica, Camellia sinensis, Plectranthus amboinicus, Curcuma longa, Rauvolfia tetraphylla. All the plant speciemens were found to contain terpenoids, xantho proteins, couramins and vitamin C. They also contain Saponins (except Curcuma longa), Combined anthroquinones (except Acalypha indica, Camellia sinensis, Curcuma longa) flavonoids (except Acalypha indica, Camellia sinensis), Carotenoids (except Acalypha indica, Curcuma longa), and steroids (except Plectranthus amboinicus, Rauvolfia tetraphylla) Quinones were found in one out of the five specimens. Some of the medicinal plant seemed to have potential as source of useful drugs. Though the one percent extracts of all the plants showed some degree of antimicrobial activity, it was significant in Acalypha indica, Camellia sinensis, Plectranthus amboinicus, Curcuma longa, and Rauvolfia tetraphylla. The extract of Camellia sinensis and Acalypha indica was most effective against Enterobacter faecalis (ZI = 3 cm and ZI = 1.7cm) and Camellia sinensis and Acalypha indica was most effective against Staphylococcus aureus (ZI = 2.1 cm).

The Yaoure gold deposit (Central Ivory Coast, West Africa) is composed of several types of ores: quartz vein, sulphide facies (45-50 m in depth), oxidized facies (35-45 m in depth) and, on the surface, a clayey zone. Therefore some physical features like permeability are essential in the heap leaching method. Taken separately, the ore associated with the clay show some recovery problems, when the humidity level is more than 12 to 15%. For this cause, the Department of science and mining resources of INP-HB has study the blending method thus to face that problem. It's consisting of mixing the clayey ore with different other types of ore proportionally to obtain a heterogeneous ore and increase its permeability thus. A leaching test has been achieved on six samples (blended clayey and lateritic ores) to determine the maximum recovery and the optimum consumption in reagents (NaCN and CaO). The tests results permit to obtain the best figure with 96.63% of reconstituted quantity recovery with reagents consumption of 1.41 kg/t in NaCN and 0.45 kg/t in CaO. In addition, some in column leaching tests must be done often to simulate the leaching in heap with the aim of determining some technical, physical and economic parameters to improve the process and therefore to increase the recovery.

This research paper is based on the estimation of errors in the formulas which are used to obtaining intermediate values of the rate of enzymatic reaction. The rate of enzymatic reaction is affected by concentration of substrate, Temperature, concentration of enzyme and other factors. The rise in Temperature accelerates an Enzyme reaction. At certain Temperature known as the optimum Temperature the activity is maximum. The concentration of substrate is the limiting factor, as the substrate concentration increases, the Enzyme reaction rate increases. Assuming a sufficient concentration of substrate is available, increasing Enzyme concentration will increase the enzymatic reaction rate. These formulas are derived from temperature, substrate concentration and enzyme concentration based mathematical functions. These formulas are used to obtaining intermediate values of the rate of enzymatic reaction. Formulas which are derived using Newton's method for interpolation are worked in conditions which are depending on the point lies. If the point lies in the upper half then used Newton's forward interpolation formula. If the point lies in the lower half then we used Newton's backward interpolation formula. And when the interval is not equally spaced then used Newton's divide difference interpolation formula. When the tabulated values of the function are not equidistant then used Lagrangian polynomial. Mathematical expressions are derived for estimation of errors using intermediate values and formulas. All expressions are worked in n limit which is the optimum limit.

The study area is the N'zo-Sassandra watershed (Ivory Coast) located between longitudes 7°15' and 8°05' West and latitude 6°50' and 7°50' North. Its surface is estimated at 4310 km2. The climate regime prevailing at the N'zo-Sassandra watershed at Kahin is a mountain climate (subequatorial regime) with annual rainfall amounts sometimes exceeding 2000 mm. N'zo-Sassandra has a single hydrological regime. The N'zo-Sassandra watershed is a part of the West forest zone characterized by a degraded dense forest. This study aims to identify trends in the rainfall-runoff relationship from an overall conceptual modeling monthly runoff. The data (rainfall, ETP, flow) used in this study cover the period of 1980-2000. The methodological approach is based on the one hand, on the evaluation criteria of the model used (GR2M) and secondly, on the crossed simulations method (1980-2000). The results showed that the GR2M model was efficient and robust on the N'zo-Sassandra watershed. Indeed, the values of the Nash-Sutcliffe obtained are greater than 60% in the calibration phase (81.95%) as validation phase (72.40%). Degradation recorded at the Nash-Sutcliffe criterion passing the validation phase in the calibration phase is less in absolute value than 10%. In addition, it is shown that there is a vast majority of the positive signs in relation to the negative signs. These results highlight the existence of non-stationarity of the rainfall-runoff relation at the N'zo-Sassandra watershed during the period 1980-2000, suggesting a rising trend of monthly runoff.

Deepbite and open bite presents an orthodontist with challenge in any of its much form. Diagnosis, treatment planning and appropriate mechanics form a backbone of successful orthodontic treatment of these kinds of vertical problems. Patients with this kind of malocclusion can be diagnosed clinically and cephalometrically, however, diagnosis should be viewed in the context of the skeletal and dental structure. Vertical growth is the last dimension to be completed, therefore treatment may appear to be successful one point and fail later. Some treatment may be prolonged if begun early. This article reviews diagnosis, control of vertical dimension which aims at striking a balance between the soft- tissues and the dento - alveolar and skeletal structures. So far various techniques have been tried both successfully and unsuccessfully, both surgically and orthodontically (Even a combination of both).

The plant Artemisia vulgaris is a perennial weed, belongs to the family Asteraceae, and locally known as Tarkha in Dir and Swat regions of Khyber Pakhtunkhwa (K.P.K), Pakistan. The present study aimed to evaluate the larvicidal activity of methanol extracts of roots, stem and leaves of Artemisia vulgaris against Culex quinquefasciatus. The 3rd and 4th instars larvae of Culex quinquefasciatus were exposed for 24 hours to various concentrations (50, 100, 500, 1000, and 1500 ppm) of methanol extracts of different parts of Artemisia vulgaris. The leaves extract resulted in significantly higher (P0.05) mortality when compared to the mortality caused by the root and stem extracts. The LC50 value for roots extract was 9141.0 ppm, stem extract 2224.2 ppm and leaves extract 803.2 ppm. The findings of the present study presented the methanol extract of the leaves of Artemisia vulgaris as a good source of preparations for pest control especially mosquito control.

This article proposes to prove economically the existence of a second level digital divide in Morocco. We have well designed and administered a questionnaire to approach 1030 persons living in the two largest cities of the Kingdom: Rabat and Casablanca. It seemed to us at the appropriate time to get down working in these big cities where normally there should not be any digital divide, at least the one of first degree, in order to detect inequalities in the use of the Internet. By the present field work we seek to determine far beyond Internet access, a kind of persons being behind the second degree digital divide. Our results lead us to say that the use of the Internet in the cities is influenced by socioeconomic position and the living conditions of individuals. The second degree digital divide is omnipresent. These results are enough to put into perspective the effectiveness of policies to ensure a wide coverage of the country by the ICT expected to create the added value and improve the living standards and social wellbeing of citizens.
