The so called lin- earities define a class of Laplace and Fourier transform which include many of the previous transform as special cases.The linearity of both transform helps to identify those assumptions that are needed to define Laplace and Fourier transform with the properties that we require a certain techniques to solve the function by using non-local operators.Item OPTICAL PROPERTIES OF SMALL SPHERICAL PURE METAL IN PASSIVE AND ACTIVE HOST MATRICES(Wolkite University, 2021-12-17) Girma Berga KeretaIn this thesis, we have studied the optical properties of small spherical pure metal in active and passive host matrix. One of the optical properties we have investigated by this work is the local eld enhancement factor for small spherical pure metal in passive and active host matrix. The results show that for small spherical pure metal there is only one maxima of the local eld enhancement factor in both the passive and active host matrix. We present an analytical and numerical method for optical bistability of small spherical pure metal in passive and active host matrix. Using the derived analytical and numerical results we calculated the cubic equation of the optical bistability of small spherical pure metal embedded in passive and active host matrix. To observe considerable di erences on the onset and o set parts of the plots of optical bistability for the active host matrix, we took the integer multiples for the imaginary part of dielectric function of the host matrix ( ′′ h), (i.e. ′′ h = −2, ′′ h = −3 and ′′ h = −4). The third main target of study was to derive the analytical and numerical results of the real and imaginary parts of refractive indices for small spherical pure metal embedded in a host matrix. We have plotted the graphs of the real and imaginary parts of the refractive indices of the analytical and numerical results for small spherical pure metal in active and passive host matrix. The numerical and analytical results show that the local eld enhancement factor is extremely enhanced, the optical bistability activation and the real and imaginary parts of the refactive index are increased when the small spherical pure metal is embedded in active host matrix (i.e. the natural or original property of the imaginary part of the dilectric function of the host matrix is a ected by applying additionalexternal dilectric function on the host matrix).Item SYNTHESIS AND CHARACTERIZATION OF MORINGA OLEIFERA WITH REDUCED GRAPHENE OXIDE NANOCOMPOSITE FOR ADSORPTIVE REMOVAL OF IRON FROM GROUND WATER(Wolkite University, 2023-01-30) FELEKE GUADIETreatment of potable ground water in rural areas is still a serious problem in Ethiopia. This studywas conducted to investigate low-cost, environmental friendly and innovative composite adsorbent(rGO/MO) for the removal of elevated ferrous iron (Fe2+) from three randomly selected shallowwell water samples. All water samples were analyzed by different parameters like pH, temperature,electrical conductivity, turbidity, TDS, TSS, hardness, chlorides, alkalinity and Fe2+Concentration. The results of the study were ranged as pH (6.52-–7.22), Temperature (21.3–22.7 ℃), E.C (76.8–151.3 µS/cm), turbidity (15–22 NTU),TDS (79.2–121.3 mg/L), TSS (50–100mg/L), hardness(120–280 mg/L), chlorides(93–125 mg/L), alkalinity (200–550 mg/L) andFe2+(0.62–0.66 mg/L). The values of most of the parameters such as pH, conductivity, temperature,TDS, hardness, and chloride content were within the permissible limit of WHO and EEPA.However, the concentration of Fe2+ was above the maximum permissible limit set by WHO.Similarly, the values of physicochemical parameters such as turbidity, TSS, and alkalinity wereabove the acceptable range for drinking water limit set by WHO and EEPA. Thus, the resultshowed that the potable ground water collected from rural areas pose a risk to human healthunless a proper water treatment system is implemented. The investigated adsorbents (MO, rGO,and rGO/MO) were characterized by FTIR, SEM, XRD and UV-Visible techniques. An adsorptionresults showed remarkable adsorption capacity (qmax) of 44.6 mg/g as obtained from theexperiment. The adsorption efficiency of rGO/MO adsorbent for elevated ferrous iron removal wasaffected by parameters like initial metal concentration, contact time, pH, and adsorbent dose. Thehighest adsorption efficiency was observed (99.2 %) at pH 9. The optimum contact time for theadsorption process was found to be at 50 minutes. The amount of Fe2+ ions adsorbed decreaseswith increasing in initial metal ion concentration. FT-IR data indicated that the adsorption ofmetal ions occurs on the surface of rGO/MO powder as the main functional groups that areresponsible for metal ions binding are involved in the process. The Langmuir isotherm data Fe2+has good fit with the experimental data (R2=0.994) than Freundlich isotherm data Fe2+(R2=0.979)Item Theoretical Investigation of Size and Shape Dependent Melting Temperature on Transition Metal Clusters(Wolkite University, 2023-06-08) Kibatu TiruhaThis thesis mainly presents the study of theoretical investigation of the size and shape dependent melting temperature on transition metal clusters (Cr, W, and Mo) with their special parameter of shape factor are theoretically and analytically used in thermodynamic mode. Particle shape is considered by introducing a shape factor. According to our study, if the size of particle decreases, the ratio melting temperatures of transition metal clusters increase, and if the shape factor of the parameter increases, the ratio melting temperatures of transition metal clusters decrease. The melting temperature generally decreases with increasing cluster size, due to the increased surface-to-volume ratios. This increased ratio makes it easier for the atoms of the surface to escape from the cluster, leading to a lower melting temperature.Item CHEMICAL DEPOSITION OF POLYANILINE ON THE SURFACE OF MORINGA OLIFERA SEED FOR WASTEWATER TREATMENT(Wolkite University, 2023-06-19) AYANSA FIKADU G/MARIAMWater technology advancement coupled with environmental concern, increasing water demand, and the living standards of society led to the technology that provides clear water to the ecosystem. This study was give best alternative that surface modification of PANI on MO in which low-cost, effective, and environmentally friendly adsorbents new and innovated for water treatment technology. Thus, PANI/MO was synthesized by in situ oxidative polymerization of aniline on moringa olifera seed for wastewater treatment applications and study the physico- chemical parameter of wastewater generated from Enamor Woreda, Gurage Zone, SNNPR, Ethiopia. The values of most of the physicochemical parameters, and heavy metals were above the acceptable range for wastewater discharge limits set by WHO. The correlation coefficient of physico-chemical parameter between the four wastewater sampler was strong, and moderate correlation between all parameter(TDS,EC,TSS, pH, TA, and TH), while weak correlation between turbidity TDS, EC, TSS, pH, TA, TH, and Temp. The prepared nano-composites were characterized by powder XRD, FT-IR, UV spectroscopy and conductimeter. SEM and XRD studies reveal that the crystal structures of embedded MO were amorphous with semi-crystalline, while PANI, PANI/MO nanoparticles distorted and become porous with polycrystalline. Vibrational spectra analysis confirms that adsorbed PANI nanoparticles on the surface of MO acts as a compensator for positively PANI nanoparticles in the formation of PANI/MO nano composites. UV-visible spectroscopy showed that PANI/MO has a smaller band gap compared with MO; this implies that PANI/MO has a higher probability of absorbing light, being optically active, or being chemically reactive. The experiment found that the PANI/MO composites had a best adsorption capacity for copper (10.01 mg/g) and lead (23.01 mg/g) in simulated wastewater solutions. When all parameters were optimized (pH at 5, contact time at 30 minutes, temperature at 250c, and 2 gram of PANI/MO) removal adsorption efficiency for Pb2+ (99%), and Cu2+ ions(97.77%). The Freundlich isotherm data for Cu2+ and Pb2+ have a good fit with the experimental data (R2 = 0.99 and 0.98), respectively. Cu2+ and Pb2+ Langmuir isotherm data (RL=0.18 & 0.19). The pseudo second order kinetic isothermal was more fit with physic-sorption at (R2=0.99 for Cu2+ and R2=1 for Pb2+ ). The PANI/MO composite shows antibacterial activity against the bacterial species.Item NUMERICAL SOLUTION OF LINEAR FREEHOLD INTEGRAL EQUATION OF BY USING NEWTON-COTES QUADRATURE METHOD(Wolkite University, 2023-06-20) SHEGA GASHAWIn this thesis, we discussed the numerical solution of the linear Fredholm integral equation by using the Newton-cotes quadrature rule and the Lagrange interpolation method. Lin ear Fredholm integral equation which can not be easily evaluated analytically. This thesis was concerned with the numerical method. Newton-cotes quadrature method was used to transform the linear Fredholm integral equation into a system algebraic equation. It shows that the approximate solution is uniformly convergent to the exact solution. In addition to demonstrating the efficiency and applicability of the proposed method, several numerical examples are included which confirm the convergent results. After introducing the type of integral equation we were investigate some numerical methods for solving the Freehold in tegral equation of the second kind. For the numerical treatment of the Freehold integral equation, we implemented the following numerical method; the Quadrature method and the Trapezoidal rule. The mathematical framework of these numerical method with their convergence properties was presented. These numerical method will be illustrated by some numerical examples. Comparisons between these method was drawn.Item NEW CONTRIBUTION IN BEST PROXIMITY POINT THEORY VIA AN AUXILIARY FUNCTION(Wolkite University, 2023-11-01) Abebu Getyein this thesis, we introduce the notion of proximal τ -distance contraction, proximal contractive and proximal T -contractive mappings. We establish best proximity point theorems, there by extending fixed point theory to the case of non self mapping and we prove the existence and uniqueness of a best proximity point for such types of mappings in a Hausdorff topological space. Examples are given to validate the main results.Item SCREENING PLANT GROWTH PROMOTING ATTRIBUTES OF RHIZOSPHERIC PSEUDOMONAS SPECIES FOR ABIOTIC STRESS TOLERANCE ON SORGHUM(Wolkite University, 2023-11-01) MEKDES MULUGETASorghum is an economically important crop that is used for food, feed, and biomass production worldwide. Despite its economic importance, sorghum productivity is affected by biotic and abiotic stresses. By encouraging plant water-use efficiency, osmotic stress tolerance, and root development, PGPR (Plant Growth-Promoting Rhizobacteria) application assists in preventing drought and improves plant resilience and survival in environments where water is scarce. Therefore, the application of (PGPR) in sorghum demonstrates promising potential for sustainable and resilient agricultural practices. The present study aimed to screen the growth-promoting attributes of Rhizospheric Pseudomonas spp. for abiotic stress tolerance in sorghum using a combination of techniques and approaches to gain a comprehensive understanding of the interactions between the Pseudomonas rhizospheric bacteria and the sorghum. Based on this there is a need to improve agricultural sustainability and chemical effects on the environment using PGPR. The sample was isolated from different areas of Ethiopia, and 210 isolated bacteria were screened using the serial dilution method. The response of PGPR was tested under temperature, pH, salt, and drought stress. The genes implicated in PGPR were amplified using PCR (polymerase chain reaction), and the bacteria were identified using 16S RNA. Based on biochemical tests 68 showed nitrogen fixation and 50 showed phosphate solubilization. Based on molecular examination, of the 68 isolates, 16 were positive amplifications for the nifH target amplicon and 10 for the acdS target amplicon, and of the 50 isolates, 21 were positive amplifications for the pqq target amplicon. Using the R software analysis, the Pseudomonas MS-22 isolate demonstrates its potential as a growth- promoting rhizobacteria; further research is required to identify optimal strains and application methods for sustained benefits. The implications of these findings extend to the realm of sustainable agriculture, where harnessing the potential of Pseudomonas MS-22 could pave the way for eco-friendly and efficient agricultural practices.Item THE PREVALENCE AND IDENTIFICATION OF ANTIBIOTICS RESISTANCE GENES IN COMMON UROPATHOGENS ATTENDING ATTAT HOSPITAL ETHIOPIA(Wolkite University, 2023-11-01) WONDWESEN MITIKU SISAYEUrinary tract infections (UTIs) are infections of the urinary framework (the kidneys, ureters, bladder, and urethra). UTI occurs when bacteria, primarily from the genital area or the stomach-related tract, stick to the entrance of the urethra and start to spread. In Ethiopia and the Gurage Zone specifically, there is a significant research deficit regarding the identification and prevalence of antibiotic resistance genes in common urinary tract bacterial infections. The aim of this study designed to estimate the prevalence of uropathogenic bacterial urinary tract infections and identify individuals with genes associated with antibiotic resistance at the Attat Hospital, Ethiopia. A cross-sectional study involved 384 across-section were involved in the current study patients from the Attat Hospital. Culture on Blood, Macconkey and Nutrient agar was carried out after a dipstick urine examination. Using the gram stain and biochemical testing, pathogenic bacteria were isolated and recognized. The Kirby Bauer disc diffusion method for determining antibiotic sensitivity and resistance employed erythromycin, cefepime, tetracycline, clarithromycin, vacomycin, pencilin, and ciprofloxacin. Genomic extraction and PCR amplification for detection of tetraA , vanA and blaSHV antibiotics resistance gene were done. According to the proportion of participants who experienced UTIs during the research period, the prevalence was 75.0%. Staphylococcus aureus was the sole Gram- positive bacteria found; other Gram-negative bacteria included Escherichia coli, Klebsiella pneumonia, Entrobactor aerogenes, Protus valigaris, Proteus mirabilis, and Pseudomonas aeruginosa. The most often isolated bacterium was Escherichia coli (49.3%), whereas P. aeuruginosa was the least frequent (2.8%). The most effective antibiotic for all bacteria was ciprofloxacin, and the isolates tested negative for tetracycline. The molecular investigation identified three different genes with E. coli, K. pnumoniae, and S. aeurus, respectively: 53.8% tetA, 54.2% blaSHV, and 78.6% vanA. In order to prevent multidrug resistance, which would otherwise have an influence on the rising cost of care, the study advises regular surveillance and investigation of antibiotic use in the therapy of UTI. The need for future molecular analysis of antibiotic resistance genes cannot be overstated.Item ISOLATION AND MOLECULAR DETECTION OF ANTIBIOTIC RESISTANCE GENE OF STAPHYLOCOCCUS AUREUS FROM COW MILK SAMPLE IN WOLKITE DISTRICT ETHIOPIA(Wolkite University, 2023-11-01) AYANSA KEBENESSA MEDEKSAStaphylococcus aureus is one of the most frequent organisms known to cause food poisoning and other diseases including humans and animals. Raw milk is known to be a major means of transmission of this pathogenic bacterium to humans and animals. This study aims to isolate, characterize, and molecular detection of antibiotic resistance genes for Staphylococcus aureus from cow milk samples collected from wolkite, Ethiopia. A total of 385 samples of cow milk were collected randomly. Each of the samples collected was serially diluted, cultured on blood agar, and incubated at 37 oC for 24hr and preliminary screening for possible Staphylococcus species isolate was conducted. The secondary screening for possible Staphylococcus aureus such as coagulase test, fermentation of mannitol salt agar, anti-biotic sensitivity tests, and molecular characterization for nuc gene and mecA genes were conducted. A total of 30 possible Staphylococcus species were isolated and 21 isolates were screened as S. aureus based on the advanced biological identification software. The rest of the isolates were found to be positive for catalase, triple sugar iron tests, cocci in shape, positive to gram staining, non- motile, and negative to vogues pressure tests. Some of them were coagulase- positive and 60% were positive to mannitol salt agar. All tested isolates were resistant to penicillin, 53.9% were multidrug-resistant and most of them were sensitive to clindamycin. Under the PCR detection of antibiotic resistance genes, 70% of the possible isolates were found to have the mecA gene while 80% were positive for the nuc gene. These isolates were predicted to be S. aureus subsp. aureus, S. cohnii, S. intermedius, and S. vitulinusin which nearly all of them have belonged to S. aureus subsp. aureus following the methods of advanced biological identification software identification tools. In conclusion, the recent isolates obtained from raw milk harbored specific genes responsible for disease-causing that were reported and available in the genomic DNA of S. aureus throughout the history of evolution.Item Common Best Proximity Point Theorems of Generalized Proximal (ψ, φ)-Weakly Contractive Mappings in b-Metric-Like spaces(Wolkite University, 2023-11-01) ABDREZAK AHMEDINIn this thesis, common best proximity point theorems for generalized proximal (ψ, φ)-weakly contractive mapping in the cases of non-self mappings are proved. We introduced the notion of generalized proximal (ψ, φ)-weakly contractive mappings in b-metric-like spaces and proved the existence and uniqueness of common best proximity point for generalized proximal (ψ, φ)- weakly contractive mappings in complete b-metric-like spaces. We also included one example supporting examples that our finding is more generalized with the references we used.Item IMPACT OF CLASS SIZE ON ACADEMIC ACHIEVEMENT IN CHEMISTRY AT PUBLIC SECONDARY SCHOOLS OF SEBETA AWAS WOREDA, OROMIA REGION(Wolkite University, 2024-01-01) FIKADU EJETA TUFAThis study assessed the impact of class size on academic achievement of chemistry in secondary schools in Sebeta Awas Woreda. The study used descriptive survey research design whereby both qualitative and quantitative approaches were the basis of data collection and data analysis. A sample of three public secondary schools was selected using the simple random sampling technique. The population of the study comprised all the eight chemistry teachers, three principals, one vice principal, one supervisor and one hundred sixty-two students. Data was collected using questionnaire, interview, observation and document review and the analysis of the questions was done using descriptive statistics, frequency, percent, mean and standard deviation. The research questionnaires were validated by advisor, supervisor and two senior science teachers in secondary schools of Tefki and Awash Melka and the pilot-test method was used to ascertain its reliability with coefficients of 0.92 for the teachers’ questionnaires and 0.98 for the students’ questionnaires. The findings revealed that class size had negative impact on academic achievement in chemistry. It was also observed that class size has psychological and social impact on students’ academic achievement and negatively influence teacher’s quality of work and assessment, whereas, they are improved by small class size. It was recommended, among other suggestion, that governments should prioritize the construction of more building of additional classrooms and the employment of more teachers to provide solution to the problem of high students-teachers ratios. The students-teacher ratio should be 45:1 as suggested by National Policy on Education as against 70-112 and above as discovered from the study. As a long-term measure, the government should increase budget allocation to improve schools’ infrastructural facilities.Item ASSESSMENT OF PHYSICOCHEMICAL PROPERTIES AND HEAVY METAL CONTAMINATION IN HORA HARSADE WATER, BISHOFTU, EAST SHOA ZONE, OROMIA, ETHIOPIA.(Wolkite University, 2024-01-01) Naol AssefaHora is a type of ground natural mineral water which are used as a source of mineral supplement for livestock. It has the medicinal value to protect the animals from different diseases and useful for their health growth. The aim of this study was to assess Physicochemical Properties and Heavy Metal Contamination in Hora Harsade Water, Bishoftu, East Shoa Zone, Oromia, Ethiopia. The Hora water samples were analyzed for physicochemical parameters and heavy metal concentration using a DR/2400 UV-vis spectrophotometer, flame photometry and ICP OES by following standard methods and laboratory procedures. The experimental procedures were set according to the international drinking water standards set by American Public Health Association (APHA). The study was carried in Winter, Spring and Summer, 2024. A total of 15 physicochemical properties and 5 heavy metal concentrations were analyzed in order to understand the characteristic and quality status of the Hora natural mineral water with temperature, pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), Total solids (TS), Total Alkalinity (TA), Total hardness (TH), Dissolved solids (DO), Na, K, Ca, Mg, Chloride ion (Cl-); and heavy metals like: Cu, Fe, Zn, Mn and Cr. The results were evaluated with national (NDWQS, 2013) and international (WHO, 2018) drinking water standard values for human and livestock. The recorded mean concentration of temperature 19.37±0.15 0C higher than 15 0C WHO, TSS (91.33±1.15 mg/L) which is above WHO (30 mg/L), Na (318.39±11.35 mg/L) is above 200 mg/L (NDWQS and WHO), and Mn (0.56±0.05 mg/L) which is above permissible limits of NDWQS (0.5 mg/L) and WHO (0.1 mg/L). All the rest listed above properties of water were observed within the recommended permissible limits of CES and WHO standards that agreed with domestic water quality level. Based on the current study result the Hora Harsadee spring water is suitable for domestic purposes after moderate treatment of temperature, TSS, Na & Mn. For more detail quality monitoring, other physicochemical, toxic metals and microbial analysis have to be done in order to have a broader picture of those spring water quantity.Item FACTORS AFFECTING 10TH GRADE STUDENT ACEDAMIC PREFORMANCE IN CHEMISTRY(Wolkite University, 2024-01-01) URGESSA OLANA TERFAChemistry has been identified as a very important school subject and its importance in scientific and technological development of any nation within the context of science education. This study aims at investigating factors that influence performance of Chemistry in Fincha secondary schools in Abay Chomen District of Oromia regional state, Ethiopia. The data was collected using questionnaires to both students and teachers; class observation schedule and interview to principal. Descriptive and inferential statistics was used to analyze the collected data. The descriptive survey was employed to identify students attitude, assess the professional qualification of teachers; and analyze the teaching and learning methods used and learning resource needed in teaching the subject. The inferential statistics was used to support these descriptive survey of the study. The finding of the result revealed that, attitude of students towards chemistry; professional qualification of Chemistry teachers; teaching and learning methods used in teaching Chemistry subject and teaching and learning resources needed in teaching of Chemistry subject were the factors identified that hinders the students’ performance toward the subject. Moreover, the result indicate that, eventhough majority of the students were very positive toward learning Chemistry subject, their performance is far below average and they seem to score low grade in Chemistry subject. Therefore, chemistry teachers should use student centered method of teaching, the school should strive to provide adequate resources to increase students’ performance in chemistry subject in the study area and teachers should organize symposium to sensitize students on the practical applications related to the subject and carrying out continuous evaluation test were recommended.Item AN INVESTIGATION OF ASSESSMENT TECHNIQUES USED BY MATHEMATICS TEACHERS(Wolkite University, 2024-01-01) TADEWOS MASAThis study was conducted to investigate the assessment techniques used by mathematics teachers, grade 10 in focus. Specifically, to gain an understanding of extent to which teachers use different assessment methods and teaching processes. The investigation adopted descriptive survey which intended to produce statistical information about an issue under the study. The data were obtained from students and mathematics teachers of Wachiga esho, Ges uba and Mure secondary schools. For questionnaire survey, 122 students were selected by u sing simple random sampling method and 8 mathematics teachers were purposively chosen as representative samples. The study used a questionnaire and interview as main sources of data collection from both the students and mathematics teachers. The data were analyzed by using the methods of descriptive statistics and Linkert type. The study revealed that though teachers have understanding about the importance of classroom assessment, they are influenced by a number of challenges. As it was observed that lack of teachers' commitment, the lack of knowledge about to effectively use assessment techniques, the lack of timely training regarding assessment techniques, students' misbehavior and absenteeism,inadequay of school resources, large number of students per classroom, and a time limit for provision of feedback. Conclusion of this study was different types of classroom assessment techniques are used to enhance students' progress. Such techniques home-take assessments, written teacher-made tests, review exercises and group assignments that can be made in a term and yearly basis. Therefore, it is recommended that, teachers require professional training in relation to how they can use various assessment methods, tools and techniques in order to plan and design future lesson.
