According to documentary evidence and expert opinion, the Dominicans programs that train master in public health and epidemiologists fail to develop them investigative skills needed to respond to social demands, when these professionals are inserted at the workplace. In order to identify the constituent elements of an effective learning of health research in postgraduate studies in the Dominican Republic, theoretical and empirical methods were used. It was found that the programs responsible for research training are the masters in public health and epidemiology at the universities UASD, UNIREMHOS, UCE and a program sponsored by the Center for Disease Control and Prevention, offered by the Ministry of Public Health. The preliminary review indicated that 63% of faculties have at least the master's degree and only 13% have specialized in education methodology training. The most obvious flaws in the education of health research are derived from the methods and procedures used in teaching.
In a strongly competing context, the cities and areas of the world resort more and more to territorial marketing and to territorial brands (“BeBerlin”, “I Amsterdam” “Only Lyon”, “I love NY”) to ensure their attractiveness with a good management of their image. In the face of this collective craze, the territorial marketing is from now on a major tool for territorial.
Certainly, this type of marketing - applied to the territory- is characterized by a theoretical complexity and a total absence of consensus on its theoretical and conceptual basis. Nevertheless, its evolution and its trends do not stop increasing because the context in which it intervenes is fast-changing and developing. Today, territorial marketing has reached the stage of branding, to do ambassador's strategy, to do digital field, etc.
In this research, having checked the literature of the attractiveness and the territorial marketing we are trying to focus on the preliminary phase of implementation of an approach of territorial marketing, on the one hand, and to propose an abstract model, which explains the necessary conditions of implementation of an approach of territorial marketing and its efficiency in the strengthening of the attractiveness of the investments on the other hand. This preliminary phase comes to put the solid bases of setting-up of a successful territorial marketing approach, made up generally of two big stages: a stage of strategic territorial marketing and another one of operational territorial marketing.
The bacteria producing beta-lactamases extended spectrum are the leading cause of treatment failure observed in the treatment of bacterial infections. This study aims to evaluate the antibacterial effects of extracts hexanical, 70% methanol and aqueous leaf Spondias mombin (Desr.) A. Juss. (Anacadiaceae) on six clinical isolates of Enterobacteriaceae producing beta-lactamases with extended spectrum (ESBL) and a reference strain. The study of the antibacterial activity of the extracts was performed by the medium diffusion method and agar dilution Mueller-Hinton. For phytochemical screening extracts, chromatographic characterization method thin layer was used. It emerged from this study that the aqueous and hydro-alcoholic extracts are actives. They are bactericidal for the majority of tested strains with MICs ranging from 0.39 to 1.56 mg / mg for the 70% methanol extract and 0,39 to 3.125 mg / ml for the aqueous extract. The phytochemical screening revealed a wealth of secondary metabolites such as saponins, tannins, flavonoids, sesquiterpenes, polyphenols, coumarins may be beneficial in the treatment of many diseases in Enterobacteriaceae.
Developing countries multiply the incentive policies on education, at least for primary education and educational equity, to improve the entire educational landscape and to address problems of poverty and insecurity affecting the most of these countries and in sub-Saharan Africa in particular. The aim of our work is to verify, first, the impact of the average years of schooling and educational inequalities (proxy of human capital) on economic growth for 65 developing countries over the period 1985-2010. Second, check if the developing country growth trajectory is explained only by economic factors such as education or requires other factors, structural and conjunctural, specific to each country.
We conclude that the effect of the average number of years of study is positive and significant economic growth of the countries in our sample and the predominance of conjunctural factors. However, it appears that educational inequalities have a negative and significant impact on the growth of these countries. The distinction between the group of low-income countries, middle and high shows the existence of a threshold below which education has no effect on economic growth.
The main purpose of this paper was to analyze recommendable technology package combining mineral and organic fertilizer that lead to agronomic and economic efficiency at farmer level. The test on six demonstration plots led to the conclusion that the treatment combining (15Kg N+15Kg P+10Kg K + 10Metric Tons of organic matter ) is efficient in Kalehe territory and Ruzizi plain because gives higher yields in terms of maize production with an average 5.3 MT of maize in Kalehe territory and 3.3MT in Ruzizi plain. Difference in yields for the two zones is mainly explained by the difference of potentials of soil productivity and production costs. Treatment combining (15Kg N+15KgP+10Kg K + 10MT Om) is the most productive in terms of additional yields that increases between 50 and 70% for Kalehe and between 15 and 36% in Ruzizi plain. On the economic aspect profitability of the same treatment (15Kg N+15KgP+10Kg K + 10 MT Om) is the highest in both zones Kalehe and Ruzizi plain. Average gross additional income attributable to the treatment combining the fertilizer package here above mentioned is 3,285$ per season and per hectar in Kalehe while the gross income attributable is 1,684$ in Ruzizi plain zones. Treatment (90KgN+30kgP+15kg K + 10MT om) is economically the most profitable in Ruzizi plain with 1,735 $/ha/harvest season. Estimated rate of financial return of treatment (15Kg N+15KgP+10Kg K + 10 MT Om) is 1.4 in Biriba, 2.8 in Kalehe-centre and 3.8 in Muhongoza. For treatment (90Kg N+30KgP+15KgK + 10MT of Om) the rate of financial return is 2 in Kiliba and 0.75 in Runingu for treatment (45KgN+15KgP+10Kg K + 10 MT of Om). It comes to the conclusion that technology package combining organic and mineral fertilizers increases significantly agronomic and economic efficiency. For farmers to increase yields and generate higher income these technology package are highly recommendable indeed.
The detailed sedimentological study of the Senonian in the Wanina basin of Aït Ourir basins attached to the northern slope of the High Atlas Marrakech, gave the deposit silty carbonato-evaporite, which are carried out in an environment of type sebkha where alternate phases of detrital inputs, under a hot and arid climate and in conditions of bridging favoring the installation of evaporite deposition, and the phases of carbonate deposits more marine installed under the action of a slight increase in sea level degenerating quickly, in an upper intertidal temporarily emerged. In general these carbonate benches mark to their surfaces a rupture of the sedimentation that is materialized by ferruginous hardened surfaces.
The mounts of the Tlemcen region are part of the Algerian national forest heritage. These landscapes offer a very interesting biological and edaphic diversity. In these physiognomic landscapes the groupings to Chamaerops humilis occupy an important place. This study aims to highlight the edaphic requirements of Chamaerops humilis in the mounts of Traras; An integral part of the northern geomorphological structures of the Tlemcen region. To end in our expectations of the physico-chemical analyses on six samples of the ground were realized.. The latter highlight the granulometric and chemical composition on which Chamaerops humilis can develop. The results show that the texture that favors good growth of Chamaerops varies between silt and sandy loam. The chemical composition of the soils analyzed reveals the edaphic variability that favors this taxon to develop.
To assess the influence of the breeding structure on the effectiveness of sexual inversion, growth performance and economic returns of Bouaké strain of Nile tilapia Oreochromis niloticus, hormonal treatment with 17-α-méthytestosterone was performed snapped installed in concrete basin (lot I), in happa) implanted in earthen pond (lot II) and concrete basin snapped without (lot III). The success rate of sexual inversion is 100% male in the three lots. The final average weights recorded were 2,35 ± 0,24 g (lot II), 2,06 ± 0,72 g (lot I) and 1,53 ± 0,65 g (lot III). The daily growth and the specific growth rate significantly different only between the Lot II and Lot III. The survival rate, the nutrient ratio and condition factor were not affected by the farming structure. The cost of producing a fry of 5 g recorded for Lot III (19,82 ± 0,40 F CFA) was significantly (p <0,05) higher than that obtained in the lot II (14,59 ± 1,49 CFA) and to that noted in the lot I (16,12 ± 0,10 F CFA). Profitability indices are 2,4 ± 0,25 for Lot II, 2,17 ± 0,12 for Lot I and 1,76 ± 0,25 for Lot III. The best results were recorded at the happas implanted pond followed by those installed in concrete basin.
Wildfires issues are part of a global problem. In Côte d'Ivoire, these phenomena are recurring and reduce, by the degradation of plant cover, crop yield. Official reports indicate each year many cases of wildfires in Zanzan with their impact on the local economy and human settlements. The present study aims to analyze the climatic conditions that trigger these lights for, identify critical thresholds of climate parameters in question to help prevent against this disaster. From data of ESA satellites ERS-1 and ENVISAT, the descriptive statistics and correlation analysis were used to conduct the study.
The results show that during the year, vulnerable periods of wildfires go from december to March with an early occurrence in Bouna. They also show a strong dependence of fire with climatic conditions including high temperatures, low air and soil humidity and easterly dry wind regime. El Nino conditions are also critical for local fire occurrence in the district.
Critical thresholds for triggering fires in Zanzan can be summarized by above 30 degrees Celsius for temperatures, below 40 percent for air relative humidity and less than 5 mm for the soil moisture.
The analysis of the Angstrom index shows that this indicates is appropriate for characterize fire danger in the District Zanzan.
The wastes generated by the care at a hospital are numerous: solids, liquids and other. They give rise to risks of various kinds for the environment and for the health of human. These risks include those related to the existence of parasites, now called medical and pharmaceuticals wastes according to the law 28 00. The present study aims to study the parasitological characterization of hospital effluents. The place chosen for the study is the hospital Mohamed V Meknes because its history (1956) and its fame as care referral center and interregional consultations radiation. It is among the most important hospitals in the kingdom. It serves a population of about 2,125,608 inhabitants in 22 disciplines. The clinical laboratory of the hospital, 25 samples were analyzed over a period of four weeks on the modified Baillenger technique.
The results showed the detection of protozoa, helminths, flatworms, nematodes, tapeworms and others. They have also identified a qualitative variation (different parasite species) and quantitative (concentration per 100ml) of the parasite load.
Football is an “industry” and clubs “businesses” characterized by competition for resources. The opportunities presented by expanding markets and the challenges of an environment characterized by increasing competition require that clubs successfully position themselves to build sustainable, competitive advantage. The main aim of the study was to analyze the effects of board composition and structure on performance of soccer management in Kenya Premium League. The study adopted descriptive research design taking 96 elected officials and 48 employees giving a total of 144 target population who understood key issues of football governance as the target population of the study. The study used probability sampling random sampling technique to select the respondents. Data was collected using both primary data collection tools. Structured questionnaires administered to the selected respondents was used elicit information related to governance structure of the Clubs whereas both structured questionnaire and secondary data collection form was used to collect information related to Kenya Football Premium League Performance. In spite of board membership being drawn from members who were not necessarily footballs, the board lacked wider representation in terms of gender, institutional representation like the government, age variability making the board not to have the face of Kenya, that is most clubs were aligned to specific tribe or counties, the idea which was a replica of their respective boards.

Affective computing and consumer behavior have evolved to give way to sentiment analysis either invasively or interactively. There are some tools that facilitate affective computing such as CRM and recommender systems. These are studied to analyze their objectives, applications and performance, without neglecting the evolutionary process that have suffered through the years. Also relevant is the direct impact of affective computing companies that use it, and the process that this implies. Its application to predict and give consumers new products is a reality in today's market, increasing company profits and enabling approach to the consumers never has seen before.
This study aims to determine the impact of fortification of wheat flour by the undefatted seed of Citrullus lanatus (Cucurbitaceae) on blood biochemical parameters and biometry of organs. Thirty (30) rats were fed for 14 days with six diets. A control casein diet (RTC), a classic bread diet (RPC) and four diets fortified bread (RPFnd) where wheat flour was substituted for the rate 5% (RPFnd5); 10% (RPFnd10);15% (RPFnd15) and 20% (RPFnd20) by undefatted seed meal of Citrullus lanatus. After the experimental period, the animals were sacrificed and their blood is levied to assay metabolites. Their organs are also levied and weighed. The results indicate that glyceamia and uremia for the rat of RPFnd diet have undergone changes compared to those of rats fed by RTC and RPC diets. The fortification had no effect on other blood biochemical parameters. The animals of CBD diets had a ponderale increase kidney and stomach substitution rate of 15% and/or 20% compared to the rats of RTC diet. There was no change in other organs weight (p ≥ 0, 05) for all diets. However the rats of diet RPFnd20 had got light-colored livers. Histological studies are, nevertheless required to see if these changes have pathological consequences of these organs.
Three physico-chemical characteristics of Acacia activated charcoals were determined: the degree of activation, the specific surface and surface functions. The coals are prepared from Acacia auriculaeformis and Acacia mangium, leguminous and fast growing trees, available in Côte d’Ivoire. They were activated by chemical means, by impregnation with phosphoric acid (H3PO4). Analysis of the results indicates that the activation yields are below 50% for both types of coal. In addition, the activated carbon-based Acacia auriculaeformis has a larger surface area than that based Acacia mangium. The two activated coals have mixed surface functions, predominantly acid, which give them a dual reactivity for both anionic and cationic adsorbates.
The extraction of metal ore in the poor leads us to look for techniques and methods to extract a good amount of it (metal) low cost without passing the gangue in the solution.
For this purpose, to determine leaching parameters seen to recover the metal in a low grade ore, we proceeded to test leaching guidelines heap ore preceded by size analysis and chemical different slices to determine the working parameters that can give satisfactory results. After these analyzes guidance, we opted for crushing the ore to determine the correct job settings for a good recovery of the metal contained in the ore poor and know the slice for perfect contact between the etching solution and ore for metal recovery.
During testing after leaching, we noticed that when we respect the following parameters: a constant acid concentration of 70 g / l, a time of 64 hours, a particle size of 1,700 micron; we dissolved a good amount of metals or a yield ranging between 37.9 to 74.9% when the particle size of the ore pass 9423-850 micron.
However, leaching of the composite sample of the same ore, gives a neighbor leach performance to which is recorded with the fine ore 70.8%.
Angiosarcoma of the breast is a very rare conjunctive tumor. It is a primitive malignant proliferation of the endothelial cells of the vascular tissue of the gland. It occurs in both a primary form without a known precursor, and a secondary form that has been associated to a history of irradiated breast tissue. Both forms have a malignant behavior and a poor prognosis. We report a case of breast angiosarcoma diagnosed by histology and treatment consisting of a mastectomy supplemented by chemotherapy and radiotherapy.
Mammary tuberculosis is a rare disease even in endemic countries, accounts for 0.07℅ of all tuberculous sites and 0.025℅ to 4.5℅ of all breast tumor diseases. There is renewed interest in the spread of AIDS in developed countries. We report three cases of mammary tuberculosis, the diagnosis of which could only be based on the histology seen in the multiplicity and non-specificity of its clinical and radiological aspects.
The present study, some heavy metals (Cd, Cr, Cu, Fe, Zn and Pb) were determined in water, sediment and some tissues of Parachanna obscura, Cardisoma amarantum, Peanus monodon and Helix aspersa from Ologe Lagoon which is situated in the Agbara Industrial Estate section of Lagos State, Nigeria. This is important because it is open to surrounding industries which deposit their wastes into it. The samplings of the specimens and water matrix were done as describe by American Public Health Association procedure. The samples after treatment were taken to the laboratory for the determination of heavy metal levels in water, sediment and organisms samples by Atomic Absorption Spectrophotometer (AAS) as described by American Public Health Association. The obtained results showed that the average values Alkalinity, BOD Dissolved Oxygen and Fe in water samples were higher than the recommended values for fresh water as stated by W.H.O. Results for levels in water were compared with national and international water quality guidelines. The analysis of heavy metals in sediments indicated that among the six heavy metals tested Fe was maximally accumulated, followed by Zn Cu, Cr, Pb and Cd. The organisms showed bioaccumulation in the following pattern: Fe > Zn > Cu > Cr > Cd > Pb. In the Crab samples, cadmium, chromium, nickel and lead concentrations exceeded the tolerable values provided by international institutions. (Maximum values; Fe - 874.00 mg/g, Cu – 1.71 mg/kg, Pb – 0.02mg/kg, Cd – 0.01mg/kg, Zn – 13.78 mg/kg) and minimum bioaccumulation was recorded in the fish fry (Fe - 135.1mg/kg, Cu 0.45mg/kg, Cr 0.02mg/g, Pb 0.01mg/kg, Cd – 0.01mg/kg, Zn – 3.85mg/kg). The values recorded in this study revealed that apart from Cd, Cr, Pb and Cu the Fe and Zn were present in proportions that calls for concern. And for the rest left, even if their concentrations are not in worrying amounts now, over time the continuous intake into the body of living organisms would result in bio-accumulation of these metals and this may have injurious long term effects on both the environment and the organisms. In light of this study it is reasonable to deduce that fish obtained from Ologe Lagoon is unsafe if it is to be eaten by humans. Baring this discovery, appropriate agencies should be called into action to check these substances as soon as possible.
In this study, we propose an evaluation method of the thermal inertia for two adjoining materials to one another from the heat capacity. The expression of the capacity has been deducted from the thermal-electrical analogy in dynamic frequency regime. The influences of the exciting pulse and depth in the concrete slab and in the tow-plaster on the heat capacity were presented.
In this paper, we propose a study of heat transfer through a roadway. The expression of the temperature and heat flux density are obtained from the resolution of the heat equation and the Fourier law in dynamic frequency regime. The influence of extrinsic parameters such as coefficients of convective and radiative heat exchange and cloud cover are presented.
The authors present a preview of the accreditation process and recategorization of the University of Guayaquil, is explored briefly the process in itself. Is done also an analysis general of the cloister teaching and the distribution of students according to the mode of study: face-to-face, blended and to distance. He is an approach to the need to implement ICT in the process of teaching and learning at the University of Guayaquil based on the Horizon reports and choose the scheme of work posed by Malbernat (2014). Finally we have analyzed the results of applying the scheme of work an academic unit (computer systems race) of the University of Guayaquil and established conclusions based on the results, considering the way forward towards the implementation of technology and educational methodologies.
The poultry area knew a remarkable development in the last decades within the Moroccan and worldwide territory, but it constitutes a serious problem of public health. The genus Campylobacter is the causative agent of the vast majority of cases of human Campylobacteriosis and food poisoning throughout of origin in the poultry products. This pathogenic is and ubiquitous bacteria in the environment and livestock sector primary poultry farm and able of colonizing in the tract digestive. In effect, these stocks cause diseases with strong impact constitute a danger in constant increase such as gastroenteritis and of complications extra-intestinal. Besides, these invasives bacterium introduce a resistance to certain antibiotics, but what is worrying, that they acquired a resistance to antibiotics prescribed for the treatment of the serious epidemics. This zoonose makes a major risk of public health. To diminish the impact of campylobacteriosis at Man, it requires a strategy of conflict against Campylobacter on the whole food production circuit of animal husbandry up to the end product, implicating good health practices and installation of a system of surveillance aiming at triggering off health alerts in time and in space.
The pedagogical method selection is relevant to guarantee adaptability and to personalize each method, while working with intelligent tutorial systems. The objective of this research is just to develop a hybrid system for the pedagogical method selection for an intelligent tutorial system that contributes to knowledge management and strengthens the multiple specific intelligences of each student, in the teaching–learning process.
The proposed hybrid system has two components, a genetic algorithm and a neuro fuzzy network, Mamdani Anfis style. The hybrid approach interprets the rules base of a fuzzy system in neural networks terms, where the net simulates a fuzzy inference system of Mamdani type.
The learning algorithm works modifying its structure and/or parameters, that is to say, because of neuronal inclusion or exclusion and weight adaptability. The neuro fuzzy network learns in a supervised way, through the Levenberg–Marquardt algorithm.
An experiment was applied in order to measure system effectiveness, considering decrease in wrong attempts doing an exercise as a success criterion.
The result allows us to confirm that the selection of the pedagogical method generated by the proposal is useful, so it can contribute in a positive way to the programming teaching.
This new system enables teaching under in a personalized learning style, taking into account the students characteristics.
The study sought to explore the prevalence and societal influence on drug and substance abuse among secondary school going teenagers in the Shiselweni region of Swaziland. Exploratory sequential mixed method research design was employed. Focus group discussions with 35 learners who were drug and substance abusers were selected using snowball sampling. In-depth interviews with four principals of the selected schools were done to generate qualitative data and these were selected using the criterion purposive sampling method. The generated qualitative data were analysed using thematic analysis and were used to form items of a questionnaire given to 200 randomly selected students for quantitative data. Quantitative data were analysed using descriptive statistics, frequencies, mean and standard deviation. The study revealed that drug and substance abuse was prevalent among teenage learners and the society was encouraging drugs and substances abuse. A programme to deal with abuse problems was recommended.
Inadequate supply of power by the service provider has been an unresolved national issue which affects occupants of buildings in performing tasks indoor. This study was carried out to assess generator audit in selected residential and commercial buildings in Ibadan Metropolis, Nigeria. The study area was divided into core, transition and suburban residential zones. Multistage and quota sampling techniques were used to select respondents sampled in residential and commercial buildings respectively. Descriptive and inferential statistical techniques were used to analyse data collected. The findings revealed that the average supply of power to residential and commercial buildings in the core, transition and suburban zones were 4.37, 5.31 and 7.6 hrs; 4.00, 4.45 and 5.86hrs respectively. The study showed that regardless of the zone, occupants of residential and commercial buildings sampled depended on varying types of brand of generating sets for either comfort need or occupational purpose. Also, 47.79%, of respondents in the residential buildings in the suburban zone used generating sets that were of higher output ratings than those used in either core or transition zone. Across the zones, 71.43% of respondents in the residential buildings could not use their generators to power all their electrical devices. However, in the commercial buildings across the zones, 93.75% of respondents were able to use their generators to power all their electrical appliances indoor. The study recommended that the myriad of poor power supply that forced building occupants to procure various types of generating sets and also run generator economy should be addressed by harnessing environmentally friendly and alternative sources of energy that will foster power security.
The present study had the main objective, the quantitative and qualitative characterization of the raw wastewater of STEP Aïn Taoujdate (Morocco) in term of debit and of concentration of the parameters of pollution (TSS, COD and BOD5) which correspond to some given by entries essential for purification processes.

Also, the medium stocks in 2012 is in the order of 1230 m3 / j (debit), 408 mg / l (TSS), 969 mgO2 / l (COD) and 528 mgO2 / l (BOD5); in 2013, is in the order of 1930 m3 / j (debit), 387 mg / l (TSS), 902 mgO2 / l (COD) and 503 mgO2 / l (BOD5) and in 2014, is in the order of 1859 m3 / j (debit), 475 mg / l (TSS), 1054mgO2 / l (COD) and 491 mgO2 / l (BOD5). Also, this station works in hydraulic load exceeding the reference debit of STEP (1500 m3 / j) with Concentrations of pollutants in the order of 13755 EH (population equivalent) exceeding the maximum theoretical pollutant load for which the station was designed (13330 EH) and make sign sometimes of a sub-capacity of the system of treatment.
Oftentimes, when assessing adult student's writing skills in English as a Foreign Language (EFL) environment, teachers and students alike might find themselves at an impasse regarding the grade given in a composition. With this in mind, we have upgraded one of most used assessment tools: rubrics.
This project proposal describes the path that we have taken to design an innovative rubric that aims to improve the assessment of writing by both teachers and students alike. Outcomes of this project include increase of students’ self-awareness and independence, and the acceptance of an upgraded assessment tool.
In our upgraded rubric the proficiency categories are based on a gradient of colors for each of the relevant aspects of writing rather than on numbers (one through four), literals (A through D), among other types of proficiency indicators, with the aim of making written compositions a useful learning experience, and avoid the conflict of subjective grade.
This paper addresses a problem of choosing a data structure in the context of managing information in a general ledger.
A multicriteria approach is proposed to classify structures for recording and manipulating information to general accounting. A family of criteria is proposed and a ranking approach is adopted to perform this ranking. The results obtained make it possible to obtain a certificate of aptitude for obtaining the best data structure for the management of the information at the accounting. In addition, a sensitivity study is carried out to assess the effect of the variation in weight given to each criterion on the ranking obtained.
This study aims to evaluate the performance of the sewage treatment plant of the lagunage type with activated sludge located in the town of Skhirat of the area Rabat-Sale-Kenitra in the vicinity of the Atlantic Ocean. Sampling was carried out monthly during the year 2013 follow- up by specific physicochemical analyses in terms of the chemical demand for oxygen (DCO), the biological request oxygenates of them (DBO5) and suspended matter measures it (SM).
These parameters are measured at the laboratory by the device DCOmétre, DBOmétre as well as SM by a cellulose membrane filter. On the level of this sewage treatment plant, the output acquired in terms of DCO, DBO5 and SM is respectively of annual percentage average of about 87,26%, 88,35% and 68,37% what is very significant on the level downstream of this STEP and conforms to the national standards and international ; this is confirmed by the Test t unilateral for two matched samples represented by one p-value 0.0001 significant for the difference between the averages of entry and exitof the STEP. As well as the ratios of DCO/DBO5 and DBO5/DCO, indicate to us that the biodegrad ability is not difficult, represented respectively by values of about 2,05 and 0,49 what means what means that thisstation uses a kind of satisfactory biological treatment.
