A co-generative plant situated in Northern Italy (CPN) was used to test an approach for evaluating the environmental pros and contras of using wood chips of different origin as biofuel. The EROI (Energy Return On Energy Investment) of the plant was also assessed. Used woodchips were of the two main categories and were obtained from i) natural ligneous trees from energy crops and ii) uncontaminated ligneous biomasses from agriculture and forestry wastes. Woodchips were characterized by determining the relevant physical and chemical properties for the plant functioning. Biofuels used in CPN have different physical properties and this may be the reason explaining a lower performance of some features (LHV and bulk density) of the wood chips from energy crops compared to agriculture and forestry recovery materials. Although recovered material contained higher Cl, S and heavy metal levels than wood chips from energy crops, but LHV (Low Heating Value) and lower price of recovery materials suggested that this one could be a good alternative source of energy especially in developing countries. This observation demands frequent integrity checks of the pollutants in order to guarantee a low level of environmental risks. This results obtained enable a comparison between the different kinds of materials used and an energy analysis to assess sustainability in the studied territory.
Wegener granulomatosis is an autoimmune small vessel vasculitis highly associated with anti-neutrophil cytoplasmic antibodies and characterized by necrotizing granuloma of respiratory tract, disseminated vasculitis and glomerulonephritis. Its clinical manifestations and organ involvement arevery widely.
The etiology of Wegener granulomatosis is linked to environmental and infectious triggers inciting onset of disease in genetically predisposed individuals. Complications most often occur when the disease is not treated. Kidney disease causes glomerulonephritis with hematuria. It can quickly get worse with kidney failure, but can be prevented when the condition are controlled by medicines.
We report a case of a pregnant woman with Wegener
In the context of insufficient data in a given area, it is recommended to use hydrological models at low settings. This avoids the risk associated with the parameters of the model uncertainty increases. In this study, we propose to calibrate the overall conceptual model TANK Ubangian in the watershed. It is classified in the category of watersheds little instrumented. Analysis of the performance of the TANK model and the surface runoff coefficient show good calibration results TANK model. On average, the value of the Nash-Sutcliffe criterion is estimated at 0.73.
An ethno botanical survey was carried out with local population of Aguelmouss at khenifra province, in order to repertory therapeutic indications of spontaneous medicinal plants. So, an ethno botanical catalog was established in which medicinal plants widely used in this Moroccan area were reported with most of their pharmacological and medicinal virtues.
KEYWORDS: Medicinal plant, ethno botanical catalog, Aguelmouss, Morocco.
The medical literature from India repeatedly reports burns deaths to be high among young married women mostly as kitchen accidents due to stove blasts or cylinder blasts leading to deaths. The interviews with survivors and their families indicate that there is a deliberate attempt by women to report all burns injuries as result of accidents in order to avoid any police investigation. This is true in cases of suicides as well as homicides. Almost all women reported experiencing domestic violence and therefore the linkages of burns injuries and domestic violence are strongly established. This studied silence hinders the development of any concerted response for prevention of burns injuries. The paper argues for development of a comprehensive health system response to domestic violence in order to address the issue of high burden on intentional burn injuries amongst young women in India.
The Gascogne region, located in the South West of France, is cultivated at more than 75% of its area. To evaluate the impact of anthropogenic activities on the river quality in this region, 75 samples of river waters were collected. Major elements, DOC, silica and pH were analyzed in the dissolved fraction of these samples. The results show that the geochemical composition of the Gascogne rivers, generally reflects regional lithological characteristics. However, at some locations, very highly cultivated, these lithological contributions are accentuated by the agricultural activities. Only Cl-, Na+, DOC and to a lesser degree SO4- are influenced by the urban activities, in particular around major cities. The Gascogne rivers are characterized by an alkaline pH (pH-7.47, pH-8.11). The most abundant ions in these surface water are HCO3- and Ca2 +. These two elements represent about 70% of Total Dissolved Salts (TDS) and have concentrations going respectively from 0.61 to 6.55 meq.l-1 and from 0.74 to 6.25 meq.l-1. The Na+, Cl- and Mg2+ contents, respectively vary from 0.14 to 3.24 meq.l-1, from 0.17 to 5.23 meq.l-1 and from 0.14 to 2.62 meq.l-1. The less abundant elements (K+, NO3- and SO4-) have values less than 1.5 meq.l-1. The DOC concentrations are between 1.04 mg.l-1 and 7.96 mg.l-1. Those of the silica range from 1.29 to 5.87 mg.l-1, with 2.87 mg.l-1 like average.
The aim of this in this research work is to present an innovative approach to classification of satellite images based on Markov Random Field, MRF. Markov models are used both on single-band and multi-band images and have the advantage to take into account the spatial context in the process of the classification of multispectral images. This leds to the integration of interactions between different pixels and to extract the maximum information contained in satellite images including textures. In this research work, the classification by Markov Random Fields was applied respectively on the colored composites of the first three principal components of multispectral images Landsat TM from 1986 ,ETM + from 2003 and OLI from 2014 of the department of Sinfra containing respectively 94,7% , 97,4% et 98,4 % of the information. Markov Random Field correctly discriminate the different classes of land use with a Kappa coefficient higher than 0.8 : 0.86 for TM images, 0.91 for ETM + and 0.9 for OLI images.
A total of 18 pesticides (12 organochlorines, and 6 pyrethroids) in 32 different imported animal liver samples collected from local markets in Cairo governorate in Egypt in different seasons, were detect the contamination of organochlorines and pyrethroids pesticides using Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method. The presence of organochlorines and pyrethroids pesticides residues were determined by gas chromatography with electron capture detector (GC-ECD). The results indicated that, the pesticides residues were found in all samples and 2 samples above the maximum residue levels (MRLs). Organochlorine residues had the highest percentage of contamination and violation (i.e. 100 and 6.25%, respectively) in imported animal liver samples, whereas synthetic pyrethroid residues had the lowest percentage of contamination (i.e. 6.25%) while their percentage of violation were 0%. However, the most frequently found pesticides were P,P'-DDE and heptachlor-epoxide while the lowest frequently found pesticides were aldrin, cypermethrin and deltamethrin. Furthermore, the health risk index for heptachlor-epoxide was the greatest which may be due to its physiochemical properties. A potential regular pesticides residues monitoring program in imported animal liver should be conducted to protect the consumers' health.

The results show that there is a significant statistically relationship between the level of training of the officer, the existence or not of an information system and made a strategic planning.
Pollution of superficial waters is one of the most answered aspects in the world and especially in the Mediterranean. The Mediterranean countries like Morocco is settled in a serious policy for the conservation of resources in superficial waters or groundwater, reducing the rate of the pollution load reaching the different streams and also, practicing techniques of cleanup especially in the Mediterranean watersheds whose the watershed of Martil which represents the largest one in the north western of Morocco. The results of physicochemical parameters recorded at different stations, show a high pollution load in stations located in the center of urban and industrial areas, translated by high rates of TSS, COD and BOD5 and consequently low levels of dissolved O2. The analysis of heavy metals, have led to the remarkable presence, by location, of iron, aluminum and lead, by cons, the results showed low contents of zinc, copper and cadmium.
Traditional henna rarely causes adverse events. However, to obtain a black color, many ingredients are mixed with this plant such as paraphenylene diamine and solvents. The aim of our study is to describe severe cutaneous adverse events caused by black henna collected at the Moroccan Pharmacovigilance Centre. Materials and Methods: We analyzed the coetaneous adverse reactions associated with the use of black henna, collected during 2012 in Morocco. The severity ofreactions wasan inclusion criteria. We analyzed the characteristics of patients, adverse reactions and type of exposure. Results: Nine serious cutaneous cases were collected, which represent 6.42% of all adverse reactions related to cosmetics products. Hospitalization and sequelae were the reason of seriousness. Outcomes were favorable for all cases. Conclusion: the severity of those cases showed the importance of the pharmacovigilance of cosmetics products.

This article appears as a review on habitats fragmentation. It clarified key concepts related to fragmentation and summarized methods and tools used for assessing fragmentation. Results revealed that fragmentation understanding was perceived at different ways. However, there is an intersection between all definitions we met in the literature. Fragmentation is commonly known as the filtering of a given habitat, its size, shape and the spatial distribution of its components. At forest level, fragmentation was known to limit fauna and flora needs due to the habitat

Citrus fruits and juices are an important source of bioactive compounds; called secondary metabolites, including phenolic and non-phenolic compounds. Several studies have demonstrated the antioxidant properties of these citrus fruits.
Grapefruit, Citrus paradisi scientifically called is one of these citrus essentially consumed for its medical and antioxidant properties due to the presence of flavonoids, vitamin C and tannins.
Characterization of two varieties of grapefruit, namely; citrus paradisi yellow and blood, was carried out through a phytochemical screening. The results obtained showed the presence of tannins, flavonoids, derivatives of anthracene, quinones, several other secondary metabolites that can be responsible for important therapeutic properties and use answered in the medical and cosmetic fields.
This paper examined the relationship between Foreign Direct Investment inflows and trade openness in the South Asian economies. In literature there had been diversification about this relationship. Some studies approved positive and significance relationship between FDI and Trade Openness and some found it insignificant. Our study examined the relationship of 7 countries for the time period of 12 years from 1998 to 2010 with panel data. On our data random effects were estimated. Trade openness was measured by three indicators, in terms of imports, exports and a joint combination of both the factors. The results suggested that there is significance relationship between trade openness and foreign direct investment inflows. Trade openness has positive and significance effects for FDI inflows in South Asian countries.
The study of the reproduction of Sepia officinalis of the exclusive economic zone of Ivory Coast was made between July 2014 and December 2015 on a total of 756 specimens (399 females and 357 males), dorsal length of coat ranging between 10 and 29,5 cm. The monthly followed parameters of reproduction were the gonado-somatic ratio (RGS), the sex-ratio, the fecundity and the ovocyte diameter. The results obtained reveal that this species reproduces all the year with a strong rate of reproduction in cold season. The total sex-ratio in general shows a predominance of the females compared to the males (1:1,12; ?
The present study was undertaken with the aim of contributing to the characterization of the nonstationary variability of the hydrological regime of the Kasai River using the wavelet analysis for 1940-1999. The rainfalls and discharge over Kasai Basin have marked fluctuations with a perceptible downward trend and some shift around 1950, 1960, 1970, 1983 and 1994. The results show that rainfalls over Kasai basin and the discharge at Ilebo station patterns exhibit a strong annual oscillation and some intermittent oscillations in 2-8 years (1950-1975, 1983-1995) and 8-16 years (1970-1999) time scales. The wavelet coherence analysis reveals a weak possible connection between hydrological variables (rainfalls, discharge) and climate indices relative to sea surface temperature and atmospheric circulation over Atlantic tropical, Indian and Pacific Oceans (coherence less than 0.55).
The measurement of performance in health and safety at work is done until now by indicator of result which does not allow the reaction in convenient time and thereafter they are useless in the risk prevention. In this direction, we established our own method of creation of prospective system of performance indicator and thereafter we designed our own instrument panel in health and safety. Thus, this work will be devoted to the application in a company of reception. Then, and after having presented this company, we will constitute the team of establishment of the project to then be able to set up our system and to finally be able, to detect the limits and the constraints associated with its installation.
The Health and Safety at work is a very neuralgic field, because it represents several economic legal, social and human issues. In Morocco, the situation is still dramatic because of several factors, in particular the absence of an adapted device of management and evaluation of performance. In this direction, we accompanied several Moroccan industrial companies in order to reveal their real problems as regards industrial security. We also conceived and carried out our own method of evaluation of performance in health and safety at work. We can then at this stage clarify the various triplets {objective, variables of action, indicator of performance} constituting our instrument panel.
To this end, we accompanied these companies during several years in order to determine on the ground the variables of action necessary and sufficient to the result of each objective. We also, designed an indicator of performance for each objective. Then, with an aim of determining the indicators of performance and the variables of actions most relevant and the most adapted to the studied context. We have to collaborate with several groups in particular the operators, the team leaders, the foremen, the shop foremen, the persons in charge, the managers and the directors through meetings, brainstormings, visits and inspections of the ground, test and of the checks of various methods, organizational and practical solutions of work and management of health and safety at work. We present then in present research, our methodology of work and the whole of the triplets constituting our instrument panel.
Hepatics failure presents diagnostic, prognostic and therapeutic problems. Drugs chemicals, viral, autoimmune, vascular are some of the causes of acute hepatitis. The objective of this study is to present the main toxin involved with acute liver damage, which is faced the Urgent Medical Assistance Centre of Tunis, characterized by clinical and biological fatigue. The findings are toxic paracetamol, valproic acid, alcohol and its derivatives, certain mushrooms and medicinal plants.

In this study, we used the expressed sequence EST-SSR marker (MTIC124) to show genetic variation and determine a potential link between this marker and salt stress tolerance on two contrasting Medicago truncatula Gaertn. genotypes (Tru 131 tolerant genotype, and Jemalong, sensitive one). The amplification of the DNA isolated from 10 individual seedlings for each genotype with the EST- SSR primers (MTIC 124) produced a total of 20 amplified products. The sizes of the alleles detected ranged from 100 to 280 bp. The analysis of polymorphism locus showed that the tolerant genotype (Tru 131) population had two alleles, genetic diversity index of 0.32 and PIC value of 0.267. The results obtained from UniGene and Uniprot databases of highly similarity proteins sequences with the EST- SSR locus MTIC 124, showed that this locus encode cysteine proteinase inhibitor and was expressed principally in root of M.truncatula. This data suggest that this locus is involved in salinity tolerance and it is appropriate for studying and understanding salt stress tolerance mechanisms in Medicago truncatula Gaertn.
Bacterial resistance to antibiotics is now a major public health problem in the world as well as in Morocco. The situation appears particularly worrying in hospital since it disseminates the micro-organisms to long distance, and insidiously contributes to their transmission to various inert media. Infections favored may be reduced by the mastery of the environment and the establishment of good disinfection strategy, based on natural and powerful molecules.
In this context, we have tested the antibacterial action of two essential oils (Thymus vulgaris and Lavandula officinalis) on 27 strains collected from the environment of the Al Ghassani hospital's hemodialysis center of Fez city. The determination of the antibacterial power was conducted by the Vincent method. The minimum inhibitory concentrations (MIC) of the various essential oil were determined by the solid medium diffusion method.
The oil of Thymus vulgaris showed a strong antimicrobial activity against the strains studied with diameters of inhibitions between 16 to 40 mm. The HE Lavandula officinalis presented narrow antibacterial activities, with diameters of inhibition ranging from 8 to 28 mm. The MIC of lavender are more important than those of thyme. This activity could be due to a synergy of their major compounds.
It would be interesting to analyze the chemical composition of these oils, to maximize the impact of the factors that can amplify their efficacy, and to establish disinfection
The spatial distribution, source identification and contamination assessment of trace metal contents in the agricultural soils around Sidi Ahmed Pb-Zn abandoned mine, Northern Tunisia, were investigated using statistical methods, pollution indicators and geographic information system (GIS) mapping techniques. A total of 7 soil tailing samples, 54 agricultural topsoil samples and 9 background topsoil samples were collected. The concentrations of As, Cd, Cr, Cu, Hg, Ni, Pb, V, Zn and Zr were then analyzed. The tailings samples are extremely rich in trace metals. The maximum concentrations in the tailings were 635.4, 618.2, 156.3, 713.8, 59989 and 91691 mg.kg-1 for As, Cd, Cu, Hg, Pb and Zn, respectively.

The knowledge of the mechanical behavior is essential to predict the lifetime of components in order to avoid any sudden break in service. In this context arises our study which aims firstly to study the behavior of an ABS plate reliability(acrylonitrile butadiene styrene) artificially damaged and subjected to uniaxial tensile loading and with the aim to predict the lifetime and know the limits that must not be exceeded as this can cause failure. To measure the criticality of the damage we based this work on the theory of the unified damage, secondly to consider the stress concentration phenomenon in the sample in the presence of a discontinuity. We will also treat in this manuscript the evaluation of the stress intensity factor by an analytical calculation using the method of superposition about a combined defect. The results obtained in the light of this study allowed us to determine the different stages of damage and critical defect size which leads to the ruin of the structure.
This study aims at determining whether teaching life and earth sciences using textbooks guarantees acceptable environmental education about pollution. For this purpose, the chapters developed in the two textbooks, used to teach biology and geology to students at all levels of the middle schools were compared and analyzed. The study shows that:
- Teaching environmental pollution is interrupted in the second year.
- Chapters concerning the pollution subject are less developed in the third year in comparison to the first year of the middle schools.
- Examples used in the courses speak mainly about pollution in the region and unintentionally neglect the pollution in the rest of the globe.
- Strong lack of emphasis on educating students on the ways to minimize environmental pollution and increasing their awareness about their responsibility to protect the environment.
Taken together, this study allows drawing conclusions on the education status of middle school students on the matter of the pollution of the environment. The current textbooks used to teach life and earth sciences in middle schools do not meet the expectations to provide students with a comprehensive education on environmental pollution and which should include chapters on the pollution types and its consequences on human and wild life in other regions of the world as well as a continuous emphasis on increasing students awareness about the dangers of pollution and educating them about the ways to protect the environment.
The amino acid compositions of Azolla filiculoides, Moringa oleifera and Dialum guineensis were determined on a dry weight basis. The total amino acids ranged from 50.83-83.01g/100 g crude protein and the essential total percentage of amino acids was 42.16% (A. filiculoides), 45.64% (M. oleifera) and 45.73% (D. guineensis). Acid amino acids (aspartic acid and glutamic acid) were the most concentrated amino acids in the samples while aromatic amino acids were slightly concentrated. In all the amino acids determined, D. guineensis had the most concentrated amino acids than A. filiculoides and M. oleifera. The calculated isoelectric points were 1.7 (A. filiculoides), 1.7 (M. oleifera) and 2.8 (D. guineensis), showing they can all be precipitated at acidic pH. Methionine was the limiting amino acid in A. filiculoides. The amino acid score showed that lysine ranged from 0.44-0.94 (on provisional essential amino acid scoring pattern) translating the quality of the sources of studied proteins. The predicted protein efficiency ratio (2.70-3.81) showed that the quality of protein was high while the essential amino acid index range was 0-1.09.
The aim of this work was to compare the composition in amino acids of the samples. A. filiculoides, M. oleifera and D. guineensis can be recommended in the food of fish taking into account their food values but must be employed in limited proportions.
