This paper presents lithologic and geochemical data from the sequence of the Eocene irbit formation siliceous rocks(Transuralian Region) outcropping in a quarry in the irbit deposit(thickness of 15 m) and in a large natural outcrop, Belaya Gorka(thickness of 13 m). The data show that both outcrops are composed of diatomites and clayey diatomites, both characterized by a certain degree of lithologic heterogeneity around their chemical,granulometric, and mineralogical compositions;microstructural features; and degree of diatom preservation. The values of indices important for the classification of siliceous rocks and determination of prospects for their industrial application—SiO_2, Al_2O_3, Fe_2O_3, and clay fraction content—ranged from 66% to 77%, 7% to 14%,3.00% to 5.60%, and 23% to 50%, respectively. in all studied lithologic varieties, element abundances of V, Cr,Mn, Co, Ni, Cu, Zn, ga, Ge, and Sb were two to three times higher than their respective abundances in the Earth's crust. This is probably related to these elements' involvement in the biological cycle and favorable conditions for transport. Rb, Cs, ba, and Sr, as well as rare earth elements,are considered the most reliable indicators of lithologic and geochemical subdivision of a sequence of siliceous rocks,as they are associated mainly with clayey minerals. Variations in these indicators have recorded, with great probability, even short-term cycles and semi-cycles of silicasedimentation in the Transuralian Region, as well as tectonic regime and involvement of terrigenous influx.

Objective: The main objective was to study the disturbances of the Blood Count of children hospitalized in the general pediatric of the gabriel Touré teaching hospital. Methods: This was a prospective and descriptive study conducted from September 1 to November 30, 2018 in the general pediatrics department of the gabriel Touré teaching hospital in bamako. Data were collected on patient records using a survey sheet. Results: We collected 512 files of children out of 1030 admissions during the study period;the rate of completion of the blood count is 50%. The male sex was predominant with a sex ratio of 1.3. The majority of patients were under 5 years old (58%). The majority of fathers (56%) and mothers (64%) of children had no education;they are mainly farmers (61%) and housewives (88%). Pallor was the reason for consultation in 29% of patients and present in 60%. On blood count, anemia was present in 92% of patients, half of whom (50%) had severe anemia with a hemoglobin level below 7 g/dL. The anemia was mainly microcytic (72%) and hypochromic (66%). Hyperleukocytosis (62%), eosinophilia (68%) and basophilia (58%) were the abnormalities observed in the white line. Thrombocytopenia accounted for 40%. Severe malaria (53%) was the main discharge diagnosis and almost all patients (99%) were alive at discharge. Conclusion: The characteristics of anemia require a study of the complete blood count in healthy children with dosage of serum iron and ferritin for a better understanding of the phenomenon.

Land along the Bomboré River in the rural commune of Mogtédo in Burkina Faso is experiencing degradation. The explanatory causes of this degradation constitute the subject of this study. To do this, a survey was conducted among agricultural producers deployed along the watercourse. Soil profiles were described and samples were taken to analyze pH, soil organic carbon, soil organic matter, total nitrogen, and texture. The RUSLE model approach based on landstat8 OLi/TiRS and SRTM satellite images dated December 17, 2021 with fairly good radiometric, spatial, and spectral resolution was used to calculate the land loss rate. in terms of results, the potentially irrigable areas that spread out on both sides of the banks of the river cover 209.23 ha with a perimeter of 6.16 km. The number of irrigators is 26 producers and they grow 17.92 ha of vegetables. Soil analyzes indicate the presence of a moderate acid on the vertisol with a pH between 5.57 and 5.86. On the depth 0 - 30 cm of the horizon, the color of the horizons ranges from 5YR4/2 on the talweg and on the right bank to 7.5YR3/2 on the left bank and presents no risk of salinity because the electrical conductivity measured is less than 1dS/cm. The diagnosis of hydromechanical equipment shows that producers use 46 motor pumps for irrigation, of which 15 motor pumps run on gasoline and 31 motor pumps on butane gas with a ratio of 1.7 motor pumps per producer. The number of Polyvinyl Chloride (PVC) pipes used by producers in combination with a motor pump gives an average of 44 per farmer. in terms of mineral fertilization, the gross doses used by producers are 415.53 kg/ha of NPk and 201.55 kg/ha of urea, while the quantities of phytosanitary products are 3.99 l/ha of pesticides and 1.42 l/ha of herbicides. Agricultural activities emit about 222,436.66 kgCO2eq into the atmosphere, whose emissions from motor pumps represent 84.52% of these total emissions. The land loss estimate gives an average rate of 2.30

Summary: Optic nerve tumors are rare tumors, representing 3% - 5% of intracranial tumors developing mainly along the optic nerve and/or the chiasm. Optic nerve meningiomas are histologically benign tumors whose severity is linked to diagnostic and especially therapeutic difficulties. The Optic nerve meningioma is the second leading cause of optic nerve tumor after glioma. Observation: We report the case of a 49-year-old woman from South Asia, who consults an ophthalmology department for progressive visual loss in her right eye for about a year with her glasses and would like to renew her optical correction. Having no particular medical history apart from left unilateral blindness is known for approximately 15 years. Magnetic Resonance imaging (iRM) cerebral found a tissue mass with a clear outline and polylobules on the left temporo-peduncular. Through this case, we describe the circumstances of discovery of the disease, the clinical characteristics, as well as our diagnostic approach. Conclusion: in the majority of cases, these are benign tumours, the circumstances of which are discovered in multiple ways. A mostly unilateral and non-improvable loss of visual acuity must attract our attention. Renewing glasses may be the reason for discovering the disease. Today Magnetic Resonance imaging (iRM) remains an important and capital examination for the diagnosis and monitoring of this pathology.

Aim: This study analyzed the effect of different finishing and polishing systems on the surface roughness of a microfilled (Amaris), and a nanofilled resin composite (Clearfil Majesty Esthetic) using Scanning electron microscope (SEM) analysis and surface roughness tester. Materials and Methods: Thirty five specimens of each material were prepared in a plexiglass mold (10 mm in diameter and 2 mm in depth) and cured against a Mylar matrix strip to create a baseline surface. The average surface roughness was measured using a surface profilometer (Mahr Perthometer SP4, Germany) in three different positions on each sample before and after finishing with one of the seven finishing procedures: Procedure 1: Mylar strip (control), Procedure 2: Tungsten carbide burs, Procedure 3: Diamond burs, Procedure 4: Procedure 2 + one-step diamond micropolisher (PoGo), Procedure 5: Procedure 2 + multi-step discs (Super-snap), Procedure 6: Procedure 3 + one-step diamond micropolisher (PoGo), Procedure 7: Procedure 3 + multi-step discs (Super-snap). The obtained data were analyzed using two-way analysis of variance (ANOVA) and Duncan test at a p = 0.05 significance level. Results: Nanofilled composite showed significantly lower ra values than microfilled composite in procedures 4, 6 and 7 (p 0.05). Conclusion: Nanofilled resin composite showed significantly lower ra values than microfilled resin composite. Regardless of finishing methods, diamond micro-polisher produced smoother surfaces than polishing discs.

industrialization is a major strategy of Vietnam for the development of the countryside. One such program is the promotion of craft villages that have been successful in increasing income levels that are 5 times more than those villages mainly engaged in agricultural production. However, while such programs have brought prosperity to these villages, they have ignored the adverse effects on the environment brought about by the wastewaters from the processing plants. Would these households involved in agro-food processing be willing to pay for the establishment of a wastewater plant to address the environmental problems? What factors would influence their willingness to pay? The results of the study among the selected households in Nhue-Day River basin, Vietnam involved in agro-processing showed that the major factors affecting their willingness to pay for the establishment of a wastewater treatment plant are their level of education, quantity of households’ untreated wastewater, presence of young children who are more vulnerable to the adverse effects of pollution, experience of family members getting sick, households’ awareness of benefits from treated wastewater, capacity to pay, access to credit and membership in craft village’s Association. The study recommended that decisions on addressing environmental issues should be participatory to be able to take into consideration the socio-economic conditions of the stakeholders.
