Traditionally, management scholars have conceptualized the business model as a tool for innovation, planning and entrepreneurship. However, little is known about how the business model is applied in practice. To fill this gap, this study aims to identify how the business model could complete and renew the traditional strategic approach and also, explore from a practical point of view the use of the business model as a strategic diagnostic tool. A single case study was chosen to explore the use of the business model as a strategic diagnostic tool. The business model concept has evolved increasingly growing in the disciplinary field of strategy. This has generated several models whose main business model matrix for the analysis of business portfolios.

At last, we discuss the significance of civil aviation CBT system for the modern civil aviation professional education.
Design research literature refers to pleasure as a product benefit that exceeds just proper functioning. In other words, pleasure is an emotional benefit that supplements product functionality. So this research is interested in studying the different types of pleasures in designing upholstery fabrics and the objective measurement of the pleasure influence of designing printed furnishing fabrics on the user's attitude, which is through survey using questionnaire that contained a range of items. The result of the study indicates that there is a relationship between the different pleasures in designing furnishing fabrics and behavior change because those pleasures address the feelings that are quickly affected the behavior of the user.
The Thermal analysis of flat plate solar water heater is a complex task, because of a large numbers of parameters affecting its performance. In the last years, a lot of studies have been developed, using numerical approaches to describe and analyze the behavior and thermal mechanism of the thermal solar collector. In this paper, we develop a numerical model of the flat plate collector in forced circulation regime. We describe the basis of the model and show the comparisons with other bibliographic model. The main goal of this work is to simulate the efficiencies of the solar collector using an "4n-node model". The results are giving a very good agreement with the literature. The model is used to examine the impact of different parameters, which may affect the performance of the solar collector with single glass cover.
The goal of this study is to develop a simple intelligent urolithiasis diagnosis system. The accuracy of the system was determined by comparing the recognition rates of the Artificial Neural Networks (ANNs)-, k-nearest Neighbor (kNN)-, and Support Vector Machines (SVM) algorithms. The results showed that the ANN model was superior to SVM and KNN models in prediction. We aimed through this work to classify the subjects in three classes according to the chemical concentrations of variables (Ca, Ox, pCaOx, Ca/ Ox) using and according to their clinical status. The ANN model, used to determine the first class that contains the subjects presenting their urine a calcium oxalate monohydrate (CaC2O4,H2O : whewellite (Wh)) crystal type. This ANN model reached a correct prediction rate of 85.3%. Using SVM- and KNN model the correct prediction rate reached 82.6% and 65.55% respectively. The second class contains the subjects presenting a calcium oxalate dihydrate (CaC2O4,2H2O wedellite (Wd)) crystal type. The ANN-, SVM- and KNN model reached a 93.4%-, 94.2%- and 77.25% correct prediction rate, respectively. In third class that corresponds to the subjects who have negative crystalluria (NC), ANN-, SVM- and KNN model reached a 91.7%-, 87.8%- and 69.77% correct prediction rate, respectively. Compared to SVM- and KNN models, the developed system using ANN model has allowed us to discriminate the subjects. This system is important in clinical laboratories since it could be a helpful tool for provide information about the development, formation of urinary stones crystals and the determination of their crystal type.
The global financial crisis of 2007-08 has reverted the mounting importance of liquidity and profitability as a key concern in today's competitive business environment to generate funds internally. This study has examined the impact of the liquidity management on the performance of the 64 Pakistani non-financial companies constituting Karachi Stock Exchange (KSE) 100 Index for the period of 2006-2011. To derive the results of the study; descriptive statistical analysis, correlation analysis and multivariate regression tools of analysis were applied. According to the results of analyses, it is found that liquidity variables current ratio and the cash conversion cycle have significant positive impact on profitability (ROA). Further, results indicate that high current ratio and longer cash conversion cycle lead firms towards better performance. This study suggested firms to relax their credit sales policies, and devise inventory & collection turnover system in a wise manner to be more accessible to a large number of customers.
The use of great apes Pharmacopoeia or zoo-pharmacognosy is a very promising strategy for the treatment of human diseases due to the phylogenetic proximity of humans and non-human primates (NHP) as Bonobos. In total, more than 40 direct fields' observations of bonobos have been performed for five months. A high number of direct observations were recorded in August followed by September while there was less observations in June. The average size and composition of the group for August is estimated at 19 individuals with 8 males, 9 females and 2 young whereas the size recorded in September was of 12 individuals including 5 males, 6 females and 1 young. Physicochemical and blood-biochemical analysis results performed on bonobos urine within their natural habitat shown the presence of bilirubin in some urine specimens (a formation of an azo derivative with a diazonium salt). The presence of a lot of leukocytes in urine is an indication of Plasmodium infection since we are in Malaria endemic regions. These results confirm the evidence of great ape pathological condition and then these could be considered as a biological model for testing and/or validating the self-medication hypothesis and the anti-hemolytic effects of plants consumed by NHP that could be profitable to the sickle cell individuals. The survey revealed that the pharmacopoeia of bonobos of Lomako Nature Reserve consists of 35 plant species. The bioassay test showed that Treculia africana, a plant being part of the diet of the bonobos, inhibits the sickling of red blood cells in vitro in hypoxic conditions and can serve as a source of bioactive metabolites for promoting an antisickling nutritherapy in Democratic Republic of the Congo. The relationship between the pharmacopoeia of apes and sickle cell anemia is an original approach. Thus, it opens up new perspectives for the treatment of this hemoglobinopathy through modulating effects of secondary metabolites of plant origin on the epi-genome.
The present study carried out in Kisangani area on the biodiversity of Rodents and Soricomorpha mixed culture fields in some villages of the surroundings of Kisangani. The main goal was to evaluate the specific richness of rodents and Soricomorpha in these habitats. In 8.955 nights traps, by using the technique of trapping out of grid using the Traps Victor Rat Traps, Special Museum, Sherman and traditional trap, we collected 301 specimens of small Mammals belonging to two orders: Rodents (288 specimens: 95.6%) and Soricomorpha (13 specimens: 4.31%). These animals are subdivided in 12 species. Nannomys cf grata was the most abundant with 168 trapped animals (55.81%). Nannomys cf grata, Lemniscomys striatus (Linnaeus, 1758) and Lophuromys dudui (Verheyen, Hulselmans & Dierckx, 2002), Praomys minor (Hatt, 1934) and Praomys cf jacksoni are field species who are harmful for crops. The diversity index of Simpson "D", Shannon Wiener "H" and the equitability "E" were respectively 0.6625, 0.2358 and 0.6577. The calculated values of these indices show a low diversity with a bad distribution of trapped animals between different species in the studied crop cultivation fields. All identified species are common in the Kisangani area. It is therefore necessary to set up a control policy in order to fight against these culture destructors in Democratic Republic of the Congo.
The objective of this article is to study the link between stress and productivity of individuals who are exposed to the front office. Still underestimated and always physical and mental overload of work. Indeed, it is mainly the people who perform a repetitive task and execution that may have a negative effect on business productivity and psychic decompression problems or burnout. However, managers and business leaders do not pay much attention to this threat which can also address the moral and physical health of employees. The pragmatic leaders concerned about the achievement of profitability targets, limits them to a narrow vision of economic risks to their societies, hence they express negligence in relation to preventive measures against stress. Our work is a study on the causal link between stress and productivity through the exploitation of the Karasek questionnaire. Finally, faced with these results, we present the principles of the solution and the interest of studying the causes of Burnout.
We propose in this study to address the impact of socio-economic factors on the physical environment, especially their spatiotemporal dynamics in semi-arid and arid zone of Eastern Aur
In this work, we will study the nitrate pollution level in the groundwater of the coastal area between Sidi Abed and Ouled Ghanem (Province of El Jadida, Morocco). This area is characterized by the dominance of vegetable market gardening and cattle breeding. The aim of this study is to identify the main factors contributing in nitrate pollution. It was based on piezo-metric data, Lambert coordinate and the results of physicochemical analyzes of the water from 73 wells. The principal components analysis (PCA) was applied to all data collected. Firstly, the descriptive statistics shows that the well depth varies between 1 and 75 m with 16.5 m as average. Nitrate levels vary between 25.7 mg/l and 161.5 mg/l with 89 mg/l as average. Secondly, the results of the PCA revealed the impact of the depth, correlated with the geographic location, on the quality of 89% of the wells. However, 11% of the wells remain indifferent to this parameter. In this case, we can say that nitrate pollution is mainly due to the geological nature of the region allowing greater infiltration of nitrates.
Nosocomial infections are considered as a major cause of mortality and morbidity to hospitalized patients. Whose causes are often related to therapeutic procedures, the practice of nursing, material (equipment) available to professionals and users, behavior and habits of patients during hospitalization as well as hospital hygiene measures adopted by the establishment, and their consequences are often serious with a financial, social and psychological impact (the extension of the hospitalzation stay, socio-economic repercussion on both the patient and the healthcare establishment and the deterioration of the health state of the hospitalized...). This study aims to explore the factors inducing the IN-concerning the patienst at the Hospital El Idrissi of Kenitra using a methodology based on a survey including questionnaires addressed to patients hospitalized in the various departments and units care at the hospital El Idrissi Kenitra among a sample of 250 participants. In addition, this work has highlighted a set of risk factors inducing the IN-regarding the patient at the Hospital El Idrissi Kenitra namely: a) cultural and socioeconomic factors, b) factors related to the behavior and habits of patients c) institutional factors. The main results of this study revealed that 54% of surveyed patients not attending school; 61% of patients are from rural rather than from; 54% of participants claim that they use self-medication of antibiotics; given that 70% of patients admitted to use personal objects and materials of another patient; while 66% of patients do not wash their hands with soap after each passage to the bathroom; although 91% of respondents consume cooked meal outside of the hospital; however 62% of patients have attested that caregivers do not wash their hands between patients; Indeed, 66% admited that caregivers did not change gloves between patients. These results were supported by the absence in training and information for patients about the IN and their severity; consequently 77% of participants do not know what are called infections acquired in hospital; At the time that 94% feel badly informed about the wide extent of IN; 45% of participants believe that patients can only be achieved by the IN.
In this paper, the optimum conditions for the activation of Heulandite for the most effective parameters such as sodium concentration, stirring time and temperature was determined. The most efficient conditions was selected according to the highest ammonium removal capacity. The Activated Heulandite were investigated and compared with that of Natural Heulandite. The Activated Heulandite revealed the highest ammonium removal efficiency based on stirring time, zeolites loading, initial ammonium concentration, temperature and pH.The parameters revealed that the exchange of ammonium ion by Activated Heulandite occurred spontaneously at ambient conditions (270C). It was concluded that when Heulandite is activated under the condition of 1M NaCl, 600C and stirring time of 20 minutes, an excellent removal of ammonium was obtained.
The name in itself is an excellent source for the study of anthroponyms of people who have not set its history in writing. When researching on the population of kapsiki, I realized that the literal definition of the name gives information on the message it carries and the history of the person appointed. Starting from the patronymic passing through the hypocoristic name and teknonym to stumble at necronym, the variation of the name Kapsiki depends on its status that equally evolved in the society.
Background: The management of breast cancer is frequently based on hormone receptors [estrogen receptor (ER), progesterone receptor (PR)] and Human epidermal growth factor 2 (HER2). However, hormone receptors and HER2 status may change throughout tumor progression. The aim of this work is to correlate hormonal receptors with HER2 expression and also their correlation with other routinely used characteristics such as patient's age, tumor size, tumor grade, vascular space invasion and lymph node status in order to determine their prognostic value in infiltrating ductal carcinoma breast patients. Methods: Seventy-eight paraffin-embedded infiltrating ductal carcinoma tissues from patients of mean age 50.33 (28 to 84) years were collected and studied using immunohistochemistry to evaluate RE, RP and HER2 status. In this retrospective study, samples were collected between January 2010 and December 2013 at the Children's Hospital of Rabat, Morocco. Results: In our study, the prevalence of ER, PR expression and HER2 were 73,1%, 69,2% and 19,2% respectively. None of these biomarkers showed correlation with age, Tumor size and Lymph node. There was no association between HER2 expression and hormone receptors expression as well as their different phenotypes (ER/PR). On the other hand, we have found that HER2 was significantly associated with the presence of vascular space invasion (P=0.015), while the relationship between hormonal receptors expression and vascular space invasion was found to be not significant. Out of 78 cases, 50 patients expressed positively and simultaneously ER and PR. This relationship between ER and PR was significant (P<0.0001). In addition, the grade of tumor in our study was significantly correlated to the expression of ER (P=0.028), as well as HER2 and ER in Grade of tumor II (P=0.025). Conclusions: Our results provide valuable prognostic information to guide the decision-making process for treatment of patient with infiltrating ductal carcinoma.
The objective of this work is to stimulate the growth of Oreochromis niloticus using a simple technique for water heating during the cold period in Lubumbashi. 300 Oreochromis niloticus fry, weighing on average 10 grams and divided into two lots of 150 fingerlings were each used in ponds at a rate of one individual per m2. Two ponds of 1.5 are each was used for this study. In one pond, ten barrel, were placed to allow heated water while in the other heating system was not used and it served as control pond. The temperature of the water was removed by using 2 Minimum Maximum thermometers off water (50 cm) and 15 cm depth in water. The results show that the average daily temperatures ponds during the study period were 22
Four lots of chars have been produced from woods of Acacia auriculaeformis and Acacia mangium, 8-9 and 23-24 years old. The aim of this study is to determine the optimal age of the woods in order to obtain high quality activated carbon. From the comparative analysis of physico-chemical properties of the chars, it has been found that the relative densities increase from 8-9 years old trees to 23-24 years old trees (0.39 to 0.43 for A. auriculaeformis and 0.31 to 0.38 for A. mangium. The ashes rate decreases with the increasing of the age of wood: from 1.075 to 0.990% for A. auriculaeformis, from 1.025 to 0.925% for A. mangium. Otherwise, the rate of volatiles of the chars don't practically change whatever the age and the species (from 23.24 to 23.66% for A. auriculaeformis and from 24.40 to 24.92% for A. mangium). The same tendency is observed with the rate of fixed carbon: from 74.69% and 73.58% for 8-9 years old woods, they are, respectively 74.35% and 73.16%. We can conclude that technical, economic and environmental point of view the activation of chars produced from 8-9 years old woods can be recommended.
The growth of logistics sector has become a priority in public policy as well as determinant factor in territorial structuring strategies. And in the global competitive environment, major economic interests are increasingly expanding while other territories have difficulty to attract the indispensable economic infrastructure for their development.. The objective of policy makers being able to attract investment, generate added value, sparking the interest of any form of settlements to contribute to the economic development of the territory. The main purpose of this paper is to propose a multi-criteria methodology in order to judge the appropriateness of industrial facilities location demonstrating the decisive character of logistics in the industrial positioning of a territory.
The aerodynamic roughness height (z0) is one of the key parameters that control wind erosion. Several methods, based on satellite observations, have been proposed for performing mapping of this parameter. Among the empirical approaches that have been developed, Protrusion coefficient, PC, derived from measurement of the solar spectrum of Polarization and Directionality of the Earth Reflectances (POLDER) sensor offer the possibility of retrieving the aerodynamic roughness height. This approach was applied to Tunisian arid regions. The study area covers a grid ranging from 30.15

The common cases of skin infections are dermatophytoses which included different clinical types. Aim of this study was evaluated the effect of risk factors such as age, gender, residency, chronic diseases and existence of domestic animals. In addition to identification of dermatophytic species by direct microscopic examination and cultured on Sabouraud`s Dextrose Agar (SDA). Shows through the results that have been reached for clinical samples to 91 sample (46.66%) out of 195 samples were positive by direct microscopic examination, while the number of positive samples in culture 132 sample (67.69%). Tinea corporis was the most common (43.07%) of dermatophytoses, formed all kinds of Tinea exception of Tinea capitis ratio infected in females higher than in males. Also, all kinds of Tinea given a larger proportion of the infection of patients who live in rural areas from who live in urban areas. The highest rate of Tinea were in the age group 31-40 years. That most of the pathological cases of dermatophytoses associated with lack of chronic diseases of the 195 cases only 26 (13.33%) were infected with chronic diseases. The dominant species of fungus isolated was E. floccosum (34.84%).
The main objective of this study is to qualitatively evaluate the degree of implementation of actions and educational activities for health facilities in the F
The last international financial crisis has revealed that the internal audit is the cornerstone of the control of activities and monitoring their performance. This work will investigate on the existence of a correlation between internal audit and performance in a public administration. In this way, we begin by defining the two concepts: audit and internal audit, and bring these two disciplines to the public organization. Then, we will study the concept of performance, and how the audit will contribute to its realization. Thus, we will analyze the practical case of the Regional Investment Center. We will try to apply the theoretical approach and especially responding to the question: How internal audit contributes to the performance and governance?
In a context of increased competitiveness, territories highlight their potential and promote their achievements. Territorial marketing is the best tool, it's based on a territorial intelligence, analysis of opportunities and the adoption of segmentation and proper positioning to recruit the best investors. In Morocco, in the case of SettaPark Chaouia Ouardigha region is a strong example of devlopment of Settat city.
