In this thesis we introduce new equivalent characterizations and certain commutatorestimations on Besov spaces, Besov-type spaces and Triebel-Lizorkin spaces of variablesmoothness and integrability.We prove the continuous characterization of the space B ( )p( ),q( ) and characterization viaPeetre-type maximal functions of local means of variable Besov spaces B ( )p( ),q( ) based onthe continuous version of Calderón reproducing formula and and of variable Besov-typespaces B ( ),p( ),q( ). We prove certain estimates on Triebel-Lizorkin spaces of variable smoothnessand integrability F ( )p( ),q( ) for the commutator [V r, j ](f ), these estimates are obtainedunder no vanishing assumptions on the divergence of the vector field

Sandy soil is very poor soil of plant nutrients as well as microorganisms that contribute to plantgrowth such as bacteria. So, our research aims to assess the effect of biochar on potato plant andsandy soil in the Oued Souf region. The experiment was carried out on a private farm at Guemarcity from February to May 2022 under green house. A biochar was made from palm date residuesusing barrel technique and then manually grinded. The biochar then mixed with poultry manure atdifferent proportions 10,20,30 and 40 %. The mixtures were applied into the soil according to thedesign of the experience .We planted potato tubers at rate 6 for each treatment. We have noted apositive impact of biochar on the physical, chemicals and biological soil characteristics. Thepercentage of moisture level in each treatment has a percentage of biochar was increased by biochartreatment especially in T4 where the humidity was 90%. It modified pH of soil, so biochar reducedthe pH value in the soil to 7 in T4. As it reduced the salinity level in all treatment with biochar T4,T2 and T1 except T3. Biochar has also increased the biological activity of bacteria and fungi incorrelation with the biochar rate applied. A significant positive effect on the arieal part of the plantwas observed in plants treated with biochar. However, for the underground parts, the effect ofbiochar was not significant.

The study of Nano-semiconductors has a lot of interest due to their optical and electronic properties. In this study, described simple new method was described to prepare silver sulfide nanoparticles (Ag2SNPs). The nanoparticles compounds (NPs) were distinguished by their monocrystalline structure with an effective diameter of 50µm using scanning electron microscope (SEM). Then Energy dispersive X-ray machine (EDX), was used, and showed that there are some impurities in the sample with a concentration of 1%. As for The remaining samples, there are on impurities. As for the Transmission electron microscope (TEM), the spherical particles were the size of an effective diameter 100 nm, and the nanoparticles of the Ag2S were attributed to the surface atomic proportions shown by the sulfide nanoparticles with varying treatment conditions where they appearing the optical and electric properties, where the absorptivity of the samples ranged between (380-450)nm and the absorption coefficient between (2.9-4.9)x〖10〗^3cm and highest energy gaps according to the concentration each sample (1%,3%,5%,7%,9%),(3.31,3.33,3.37,3.42 and 3.47)ev, is Respectively.

Renal failure is considered as the most widespread health problem in Sudan andthe world. The study aimed to assess the patients’ knowledge and attituderegarding to chronic renal failure and management in heamodylsis unit inOmdurman Teaching Hospital, Khartoum State, Sudan during the period fromSeptember 2012 to October 2013. The sample size consisted of (100) availablepatients. The data was collected using a questionnaire is designed for the purposeof the study. The data analyzed by using statistical package for social science(SPSS). The study showed that renal failure spread among male with 62% and38% for female aged 45- 55 years. Also it’s spread among the low economic classof 52% of cases and 27% from intermediate education level.The study showedthat 42% of patients didn't know about chronic renal failure, 66% do routineinvestigation regularly, 63% regularly follow-up 58% of patients didn't knowamount of protein allowed with positive attitude regarding their illness. The studyconducted that the patients' knowledge were slightly adequate toward their illnessand its management and their attitude were positive.
