The problem of the boom of the oil extraction in different countries of the world is evident, the workings of crude oil exploitation have not been carried out following the standards that govern this activity since the wastes produced are sometimes dumped directly into the nature incurring a Non-responsible disposal or casualties such as the rupture of transport pipelines generated by the spillage of large quantities of crude oil, affecting the delicate balance of nature. It should be emphasized that in general the oil extraction work is located in complicated areas of access, which makes it difficult to carry out remediation work. This is why an analysis was carried out to identify variables involved in the air pollution process, specifically pollutants produced by Heavy metals and PAH’S (Polycyclic Aromatic Hydrocarbons) that are present in petroleum. This study involved the analysis of the publications of different authors (books, scientific articles, theses, reports). It was considered a population of 200 publications concerning oil pollution in the world, analyzing the study carried out by each author and determining potential air pollutants. The data were tabulated through a logistic regression analysis that allows obtaining an equation that defines the probability of air pollution.
With an aim of reducing the cost of aquacoles feed, we carried out substitution partial of an imported raw material: the fish meal (FP) by under local product: flour of ground worm (FV). The experiment undertaken on the youthful ones of Tilapia (Oreochromis niloticus), monosexe male, having an initial average weight of 6.24 ± 0.39g (average weight ± ES), consists in testing 2 iso-proteinic and iso-energy diets containing the same rates of the various ingredients. During 45 days of experiment the final average weights reached values ranging between 27.66± 4.06g and 42.46 ± 10.53g according to treatments'. The best growths and food transformations were obtained with treatments T2 and T3 (specific growth rates: respective TCS = 7.25±0.18 and 7.60 ± 0.39% and food conversion rate: respective TCA = 1.30 ± 0.94 and 1.28 ±0.76), while with food T1 one obtained a TCS of 5.90 ±0.15% and a TCA of 1.81±0.17.
Ultimately, and in comparison with the analyses of economic profitability, the results obtained, showed that the incorporation of this by-product (FV) ata rate of 15% involves a profit of 29.1 % on the financial expenses related to the station of the food without causing injury with the growth of fish. Thus, substitution partial of the fish meal by the flour of ground worm is possible and more advantageous when the fish are nourished with the fresh ground worms. It allows, moreover, the reduction of the loads related to the food of Tilapia and the valorization of this neglected by-product.
This study aims to use financial ratios to Kida model to predict the financial distress of the investment companies listed on the Iraq Stock Exchange, as well as to identify the extent of the statistical relationship of these ratios to earning per share (EPS) for those companies. The study used a descriptive statistical method, in addition to a regression model to analyze the data and test hypotheses. Model has included a number of independent variables marked by the profitability ratios and leverage, liquidity and activity.
Based on the data of 8 companies for three years, the results of this study demonstrated the ability of the companies to continue and distancing itself from financial distress, the study also confirmed that the ratios of profitability ( return on investment) and activity (turnover of assets) statistically significantly relationship affect the earnings of these companies , as evidenced by the study of the relationship positive and very strong between the independent variables and dependent variable.
The large ones and average surfaces have thirty years of uninterrupted existence in Morocco. They develop of number as well (only one hypermarket in 1986, more than 424 retail outlets currently) that in kind (food surfaces, specialized surfaces). The hour is thus with the assessment especially as regards favour done for the “Shopper”.
Obviously, the distribution companies modern of detail continue gradually in commercial fabric of nature traditional. The Moroccan “Shopper” appreciates this new form of distribution in view of favours which are done to him by the large ones and average untraceable surfaces in the traditional trade.
However, are these services in conformity with the international standards of distribution in particular as regards product quality exposed in the rays, of price, presentation, reception and post-sale service?
Admittedly, palpable efforts were made to accelerate the rhythm of development of the modern distribution in Morocco. However, of obstacles remain in particular the products expired in the rays, the lack of freshness of products, the lack of diversity of choice of the products, the insufficiency of hygiene, the reception facilities and of animation; in short all what attracts and lengthens the stay of the Shopper in the store.
Definitely, the distributors must redouble effort to reach the international standards of service of distribution to hope to overcome the traditional trade which does not disarm to ensure its survival and its perenniality.
Objectives: to take stock of epidemiology, diagnostic methods and the ecology and bacterial resistances of nosocomial respiratory infections, in order to propose preventive measures to improve the management of patients under mechanical ventilation.
Type of study: retrospective, analytical, epidemiological over a period of 30 months, from 1 January 2014 to 31 June 2016 conducted in the laboratory of microbiology of University hospital HASSAN II of Fez.
Patients and methods: All distal protected specimens (PDP), and bronchoalveolar lavages (BAL) positive from intubated patients hospitalized in resuscitation services.
The identification of the bacterial strains as well as the antibiogram was carried out by automated method and the phenotypes of resistance were determined by the diffusion methods in MH agar medium according to the recommendations of the CASFM / EUCAST.
Results: A total of 905 respiratory specimens were received of which 547 were positive (60%). VAPs were due to bacteria that were potentially resistant to antibiotics. Acinetobacterbaumanii was the most represented bacterium responsible for 33% of pneumonia acquired under mechanical ventilation.
Conclusion: In our series, potentially multi-resistant antibiotic bacteria and especially Gram-negative bacilli were the pathogens most often responsible for VAPs. The choice of the probabilistic antibiotic therapy of the early PAVM must take into account all the risk factors of bacteria potentially multi-resistant to the antibiotics and not only its time of appearance.
Haemophilus influenzae, holds a dominating role in the low respiratory infections. These infections constitute a real problem of public health especially because of the appearance these last years of resistant strains questioning the classic antibiotic treatment. This resistance mainly concerns betalactamins, in particular aminopenicillins.
A retrospective study was made over a period of 5 years (September 2011-, 2016) with the aim of establishing the epidemiological profile of the low respiratory infections to H. influenzae, determining the resistance to antibiotics of this germ to guide better the therapeutic and preventive strategies. The identification was based on the requirements in factors X and V and the production of betalactamases was looked for by means of the cefinase.
During the period of study, 123 tree strains were isolated among which 73 % resulted from intensive care units and from pneumology. The production of betalactamases for all the isolated tree strains was 31 %.
Resistant strains in the amoxicillin by production of betalactamase were sensitive to the association clavulanic amoxicillin-acid in 28 % of the cases. The resistance in the other antibiotics was 16 % in the trimethoprim sulfamethoxazole, 4.8 % in fluoroquinolones and 2.5 % in tetracyclines. No resistance in cephalosporins 3rd generation was observed.
The increasing rainfall variability in West Africa is a great challenge for crop productivity in small-scale farming systems, thus jeopardizing food security. Rainfed rice is particularly sensitive to inconsistent rainfall, especially during the reproductive stage. It is, therefore, necessary to develop management practices suited to the change of rainfall pattern over the growth seasons. In this study, the modeling technology with the rice model ORYZA (v3) was used to identify appropriate rainfed rice growing seasons for a better adaptation of farmers to climate variability. The potential yields, the favorable sowing periods, the optimum sowing dates, and the attainable yields of two contrasted cultivars were determined. After successfully calibrating and validating the model, it predicted potential yields of 5.5 to 6.5 tons/ha for the early maturing variety WAB56-104 (90-100 days), while potential yields of 4 to and 5.5 tons/ha was predicted for the late maturing variety CG14 (115-125 days). In rainfed conditions, two favorable sowing periods were identified from the model scenario analysis. The first period spans from late February to late April and the second from late July to early September. Farmers can double their actual yield of 1.5 tons/ha if they follow the recommended sowing dates and good agricultural practices. Indeed, the yield of 3.5 tons/ha was found with the variety WAB 56-104 sown on around 16 April in San-Pedro and around 2 April in Dimbokro. The yield of 3 tons/ha for the variety CG14 could be achieved if the sowing is done on around 18 March in San-Pedro and around 21 March in Dimbokro.
The purpose of this study was to examine the effects of using Instructional Geometric Activities (IGA) designed based on Van Hiele Thinking levels on Ninth grade students’ achievement. The sample of study consists of 30 students (male and females). A total of 15 students were in the treatment group and 15 were in the control group. The treatment group was taught Geometry through the regular method supported by the (IGA), while the control group was taught Geometry through the regular method used in the school without (IGA). Previous knowledge test in the scientific material and students’ performance in the previous year were used to identify students’ initial levels of Geometric understanding. Both treatment and control group students’ achievement was measured by using achievement test developed by the researcher. Using the equation (Kuder-Richardson-20), the test raw score registers a reliability of 0.82. The analysis of the test using (ANCOVA) showed that significant differences between the mean scores of treatment group and the control group in terms of the dimensional achievement test as a whole and in each of its levels.
The objective of the present work is the evaluation of the nutritional and organoleptic properties of olive oils from oil mills in the rural commune of Tagzirt, area of Beni Mellal (center of Morocco) by a physicochemical characterization of their compositions.
Fifteen samples of olive oils extracted from the Moroccan Picholine variety were collected from traditional oil mills. Physicochemical analyzes of free acidity, peroxide value, refractive index, density, K232, K270 and K, the chlorophyll content, the content of phenolic compounds, the α-tocopherol content and oleic acid proportion were conducted according to the standards of the International Olive Council (IOC).
The results were used to classify the oils studied according to their quality standards. The data obtained confirm that the conditions of harvesting, crushing and storage of olive oils affect the quality of produced oil. Therefore, we must educate farmers on the importance of improving practices and cultivation techniques and the owners of oil mills as regards the storage, processing and storage of oils.
The approach of aims doesn't ignore the approach of content. They complete each other. The aims can't be achieved without content. Also the approach of competences doesn't ignore or delete the procedural aims but it enriches and focuses on them to reach at the competent pupil who employs in a compound position all of his knowledge and skills in his daily behavior and properly overcome all difficulties at any time. Thus, both of the approaches [aims and content] should serve the approach of adequacies.
The objective of this study is to evaluate of the pollution load of waste water in the industrial zone of Tetouan. This pollution is generated by effluents from different industries installed. Analysis of waste water showed strong and irregular pollution which is prejudicial for networks and for the pretreatment station, this last is installed downstream of the pumping station object of study and consequently to the marine environment receiving aquatic (the Mediterranean). The results are compared to national and European standards.
It is not out of place at all for stakeholders to demand for performance figures after a while in post-M & A era. Outcomes are expected to match with merger or acquisition motives. The concept of organizational performance is related to the survival and success of an organization. The general objective of this work was to contribute to the general body of knowledge and research work in the area of post-merger and acquisition organizational performance and performance improvement in the Telecommunications industry. To achieve the general objective, the research was aimed at exploring how a balanced scorecard approach could be employed to analyze how to improve upon post acquisition organizational performance on periodic basis; that is to align business activities to the vision and strategy (medium to long term) of the organization, improve internal and external communications, and monitor organization performance against strategic goals. A framework was developed based on the balanced scorecard to show how a typical acquired Telecom company’s performance could be improved on periodic basis. This model or framework can be used by managers of acquired Telecom companies as it presents a holistic performance improvement strategy to ensure overall creation of value for shareholders.
Aims: This study aimed to detect and to determine the prevalence of the metabolic syndrome and its main components among the healthcare workers.
Methods: This investigation, led in 2014, included 1 078 healthcare workers in four hospitals in the north of Morocco. This study contained a questionnaire, a clinical and a biological examination. The questionnaire included three columns: the sociodemographic and professional data, the health and the individual conducts (food, harmful habits and physical activity). The metabolic syndrome was defined according to the criteria of the International Diabetes Federation Task Force (2009).
Results: In the studied population, the prevalence of the metabolic syndrome was 21.7 %. It was significantly higher in women than in men (25.9 % vs 17.3 %; p = 0.021). It increased with the age in both sexes: for 20 - 30 years (8.9 % in women and 3.4 % in men), on the 30-40 years (13.9 % and 8.7 %), 40 - 50 years (25.1 % and 28.7 %) and 50 - 59 years (52.2 % and 59.2 %). The abdominal obesity (46.7 %), the high blood pressure (38 %) and the hyperglycemia (34.1 %) were the most frequent components. To the subjects having a metabolic syndrome, the physical activity was significantly less frequent (14.5 % vs 29.6 %; p = 0.002) and the stress was more important (56.4 % vs 41.7 %; p 0.006).
Conclusion: The prevalence of the metabolic syndrome was important within the healthcare workers and especially in women. The fight against its risk factors (obesity, sedentary lifestyle, etc.) has to constitute a priority for the occupational health teams in hospital environment.

The phenomenon of the spread and increase the degree of reservation in the financial statements of the most controversial issues in contemporary accounting thought that formed the focus of attention of many accounting literature, despite exposed to severe criticism because of incompatibility with some of the qualitative characteristics of accounting information, this research provides more evidence about the level of accounting reservation in the financial reports for companies to contribute to Iraq, it also sheds light on the relationship of the accounting reservation improving the quality of financial reporting and the impact of this relationship on the value of the business in the capital markets, the reservation may be used by the company management as a way to choose between accounting alternatives are opportunistic in practice by some policies accounting applied by the companies, and in the multiplicity of accounting policies and estimates alternatives to achieve these goals, collected necessary to test hypotheses data, the study found indicators statistically significant on the level of accounting reservation in the financial reports issued by joint stock companies listed in the Iraq Market Securities.
This document, based on various studies linking wellbeing to performance, try to explain the potential impact of the wellbeing at work on employee individual performance and its consequences.
Through this study we have tried to compare the results of surveys and other official reports on this subject, which highlight in particular the correlations between well-being at work and individual performance of workers, as well as the conclusions Formulated in various studies carried out beforehand, while trying to determine their validity and more particularly to demonstrate the impact of well-being at work on the individual performance of a specific category of Moroccan executives working in a public organization devoted to the Scientific Research.
We opted for an exploratory approach in order to collect new elements that may be specific to the Moroccan organizational context.
The majority of the theoretical models previously developed by many researchers, linking well-being to work to individual performance, are valid according to our study.
Although the survey we carried out allowed us to understand the different variables of our problem, it should be noted that the survey we conducted is non-exhaustive, given that the sample chosen is limited in relation to the Different stakeholders influencing the organizational world.
The present study confronts the economic growth rate to the human development index in order to sort out the correlation links between the economic growth levels reached in relation to the social development level undergone by Congolese population and puts in exergue factors explaining this situation during the period from 2001 to 2014. Meanwhile, despite these immense resources, the Democratic Republic of Congo is classified as one of the poorest countries of the world and her population in inhuman conditions. More than 71% of Congolese people live with less than one American dollar per person per day.
The aim of this study was to evaluate the physicochemical and microbiological quality of the waters of Franceville lakes, which are real receptacles for several pollutants.
The physico-chemical parameters in situ were measured by means of a multiparameter and other chemical elements as phosphate, sulfate and ammonium were highlighted and measured by a colorimetric and spectrophotometric method. The microbiological parameters were determined by the colony-forming unit (CFU) method on selective agar media. Finally, strains of Escherichia coli were identified by biochemical tests.
The results of the physico-chemical parameters show that the waters of Lake Lacaisse have the highest temperature, conductivity, salinity and dissolved oxygen values respectively, 26.71 °C, 398.67 μs/cm, 190 mg/l and 376.4 mg/l. On the other hand, these waters have neutral pH. The results of the bacteriological parameters show that the lake Makana contains the strongest rates of coliformes totals (4.84.105 UFC/100 ml) and of presumptive Escherichia coli in 37°C (3.54.105 UFC/100 ml). Eosin methylene blue medium is the best for counting total coliforms. In addition, (6.45%) colonies of Escherichia coli were identified. So, other coliformes thermotolérants (Entérobacter Sakazakii, Entérobacter cloacae, klebsiella ozaenae, klebsiella Pneumoniae. pneumoniae).
In sum, this study shows that the water in Lake Makana appears to be more polluted than Lac Lacaisse.
Globalization has many facets. By this mean, it covers different and heterogeneous sides of the countries' life. No matter how it affects the process of development positively or negatively, the subject of the worldwide economies interconnection becomes more than before an astonishing and fertile ground of research and investigation. Foreign direct investment for instance is considered both as a concrete way to practice globalization and realize the targets of the international business network. This paper attempts to shed light on the capacity of the countries to catch the benefits of the foreign direct investment as a dynamic process to increase the participation magnitude of the country that hosts FDI in the international economics.
We investigated the impact of the kdr genotypes on the survival rate of mosquitoes exposed to insecticides in the main malaria vectors Anopheles coluzzii and An. gambiae s.s.. The genotype-phenotype interaction was investigated following two experimental designs; the first one consisted to determine the survival rate of well-characterized adult mosquito strains sharing different kdr genotypes but same genetic background to various insecticides, whereas the second one consisted to expose wild mosquitoes to the same insecticides. Two to five days old adult females were exposed to DDT (4%), deltamethrin (0.05%), and permethrin (0.75%) following WHO protocols. Alive and dead specimens were kept separately to screen the kdr mutations 1014F. The correlation between the kdr genotype and the survival rate to insecticides was investigated in An. coluzzii and An. gambiae s.s. using a logistic regression model. In the laboratory strains, after exposure to DDT and permethrin, the survival rate was significantly higher in F/F individuals comparing to L/F and L/L individuals (p<0.05). A perfect correlation was observed between the survival rate and the genotype in An. gambiae s.s.. The survival chance in this population was multiplied by 1.9 [1.2; 2.8] for L/F and 3.2 [2.1; 4.7] for F/F individuals after exposure to DDT; and 3.7 [1.8; 7.3] for L/F and 9 [4.8; 17.0] for F/F individuals after exposure to permethrin. In the wild population of An. coluzzii, the survival rate correlated with the genotype after exposure to permethrin and was significantly higher in F/F individuals comparing to L/F and L/L individuals (p<0.05). In L/F and F/F individuals, the survival chance was respectively multiplied by 2.7 [1.4; 5.8] and 3.2 [1.4; 6.9] after exposure to DDT; 2.1 [1.0; 4.1] and 4.1 [2.3; 8.7] after exposure to permethrin; and 2.5 [1.1; 5.3] and 3.9 [1.9; 8.0] after exposure to deltamethrin.
Overall, the mosquito survival rates were significantly higher in wild population comparing to laboratory strains after exposure to pyrethroid insecticides. These results suggest that additional mechanisms such as metabolic resistance might contribute to a large extend to phenotypic resistance in malaria vectors.
