Synovial sarcoma is a rare mesenchymal tumor. It occurs predominantly in the extremities especially in the region of the knee. The localization in palm hand is rare. We report a case of a 23 year-old man who present a monophasic synovial sarcoma of the left hand which presented as a painless cystic nodule. A surgical excision was performed. The result was good without recurrence. The synovial sarcoma is a rare malignant neoplasm that should be considered in the differential diagnosis of spindle neoplasms of hand.

This study focuses on investigating the effect of various solvents on the supercritical extraction of organic matter from Moroccan oil shales, with the goal of determining the optimal operating conditions that result in a high yield of high-quality oil rich in aromatic compounds. The results of this study demonstrate that the extraction yield and quality of the extracted oil heavily depend on the chosen operating conditions for supercritical or subcritical extraction of organic matter from oil shale. Additionally, the study found that phenol can effectively degrade oil shale and enable extraction of nearly all the organic matter, even under mild conditions (T = 390˚C, P = 1.2 MPa, Time = 2.5 h. Furthermore, the oils obtained through this extraction process are of high quality, with a rich content of maltenes, and a higher concentration of aromatic compounds and lower levels of sulfur than those obtained using other solvents.

The coastline is one of the country’s most important environmental and economic resources. However, it is a delicate and highly coveted environ-ment on which many factors of evolution interact, both anthropogenic and natural. This work is concerned with the diachronic study of the coastline of the Mediterranean coast, particularly the coastal fringe at the level of Tangier Bay. In order to experimentally confirm the numerical models used and to take part in the development of an accurate, reliable and rapid decision support system for the assessment and remediation of the risks of accretion and coastal erosion, the methodology followed consists of the application of automatic analytical techniques, based on a geomatics approach, using a multi-temporal photo-interpretation, a Geographical Information System (GIS) and a computerized data analysis system (DSAS: Digital Shoreline Analysis System). The change rate will be calculated from the multi-date maps (1981-96 and 2017) using the End Point Rate (EPR). To achieve our objective, the study area was divided into three sectors from East to West: El Ghandouri Beach, Malabata Beach and the municipal square adjacent to the port. The GIS analysis of the data obtained shows that the coastline is present by location and for the three periods of comparison of the remarkable zones of erosion and sedimentation.

Vegetation cover degradation is still a very common problem in many parts of Morocco;moreover, it affects straight up the amount of the annual soil loss rate. The analytical approach used in this study, respectively, includes remote sensing techniques, application of USLE (Universal Soil Loss Equation) and overlay analysis in a raster Geographic Information System (GIS) environment, employing available information on the region covering the Kalaya catchment. Thus, this procedure allowed the calculation of the NDVI (Normalized Difference Vegetation Index), the execution of two types of classification (unsupervised and supervised) for 1999 and 2010 imagery and eventually the prediction of soil erosion risk in the watershed in question. The main outcome was the production of multidate vegetation cover maps, land use maps and soil loss risk maps. The overlay of two maps allowed us to highlight the changes occurred in this area, which evidence the high anthropogenic impact on the dynamics of land use and vegetation cover. The results suggest that the outputs of this study can be used for predicting rate of soil loss, which varied from 31.68 t·ha-1·yr-1 in 1999 to 34.74 t·ha-1·yr-1 in 2010.

Recently, according to a survey carried out in Oued El Abid River by Oum Er-Rbia Hydraulic Basin Agency concerned about the surface water quality, the downstream course is undergoing continual degradation in its water quality comparable to the upstream. This study comes to localize the sources of pollution and explains the process of degradation, which affects the water quality in that area. For this purpose, an inspection of the place has been done during January 2017 to cover the entire zone limited by the affected part of river, followed by a survey, which interests to water quality and the ground-water depth. The inspection doesn’t show any direct liquid discharge into the river;meanwhile the water quality degradation is related to the underground sources through river-shallow-aquifer exchange process, when the obtained results from the survey showed that severe parameters are involved in the degradation of groundwater, as the geology and agricultural activities. Combining these results with flow direction in groundwater, it is clear that pollutants are transported to the river via the river-shallow aquifer exchange process, which affects its quality. Based on the finding results, this study will give the decision makers a simple view to a complex pollution processing.

Despite the extreme events impact on various climate events frequency and intensity in many developing countries, there has been dearth information on daily climate trends and climatic extremes. This study comes to characterize the climate type and its evolution in Morocco, specially the two regions Beni Mellal-Khenifra and Daraa-Tafilalt. RClimdex software has been used to calculate pluvio-thermal and ombro-thermic indices in the studied stations to reveal climate type in the two regions, their evolutions, and the daily extreme temperatures and precipitations. A cartographic representation has been done for the calculated indices and climatic trends in the stations from 1970 to 2016. As results, the temperature trend for hot day’s number shows a significant increase, while the cold night’s numbers, warm sequences, and precipitation are gradually decreases especially at Khouribga and Midelt. These observed modifications influence negatively the annual rainfall total in the year, the consecutive wet days, the maximums rainy days, and the increase of consecutively dry days. As a conclusion, the Martonne aridity and ombro-thermic indices, show that the temperatures and precipitations evolutions do not induce a change in the climate type for the studied regions.

During the human handwriting motion, several biological factors intervene to generate the pen-tip traces, such as the system of perception, the brain, the hand, etc.. The muscular activities of the forearm, called EMG (electromyographic) signals contain the adequate information to represent the motor commands. These signals provide an important source of information for the control of the handwriting act. Handwriting velocity has also an important role in control and generation of this complex process. Indeed, the control nervous system might take these informations into account to reconstruct the pen-tip trace. Using the relationship between the forearm muscles activities and the handwriting velocities profiles of the pen-tip moving on (x, y) plane during the handwriting motion, the present paper deals with a new identification approach, based on RLS (recursive least squares )algorithm. The proposed approach determines an inverse handwriting velocity model that allows to reconstruct the electromyographic signals of the forearm muscle. The results of the proposed inverse model are in good agreement with the real EMG waveforms.
