Fourier Transform Infrared Spectroscopy for the measurement of GeSn/(Si)GeSn

Photoluminescence (PL) and Electroluminescence (EL) characterization techniques are important tools for studying the optical and electrical properties of (Si)GeSn. Light emission from these PL and EL measurements provides relevant information on material quality, bandgap energy, current density, and device efficiency. Prior to this work, the in-house PL set-up of this lab which involves the use of a commercially-obtained dispersive spectrometer was used for characterizing both GeSn thin film and fabricated devices, but these measurements were limited by issues bordering on low spectral resolution, spectral artifacts, and poor signal-to-noise ratio (SNR) thereby resulting in the possible loss of vital information and inaccurately reported parameters. To maintain the progress of the GeSn material development toward replacing the group III-V semiconductors in the optoelectronics industry, high-resolution spectroscopy with high SNR are necessary to accurately determine the unknowns in the GeSn growth conditions, device fabrication, and material development. In this work, PL and EL characterization systems were designed, built, and aligned using a Bruker Fourier transform infrared (FTIR) set up to collect the emission from fabricated GeSn samples using an external source with an external photodetector. This thesis presents an optical setup of a Bruker FTIR spectrometer aligned with external optical components and external light sources (532 nm laser and 1064 nm laser) to achieve high-resolution spectroscopy with high SNR. The setup employs the use of OPUS operational software for controlling the components of the FTIR hardware and a LabVIEW program for controlling all motorized devices on the external optical bench. An indium antimonide (InSb) external photodetector was used with the FTIR for a wider spectral range detection. Finally, a step-scan mode of operation which required both lock-in and a chopper was used to measure various GeSn bulk and laser samples at high resolution. The results obtained from these characterizations demonstrate a high SNR spectrum compared to a dispersive spectrometer

Comparative Analysis of South West Students’ Performance in National Mathematics Olympiads Competitions in Nigeria

The main purpose of this study was to carry out a comparative analysis of the performance of South West students in the mathematics Olympiads competition organized annually in Nigeria by National Mathematical Centre, Abuja. Secondary data of the results of students for 2015, 2016 and 2017 Olympiads examinations in the six states of South West, Nigeria was collected and analyzed. Frequency count, percentage, mean and standard deviation were used to answer the three raised research questions while t-test and ANOVA were used to test the two formulated hypotheses. Results of the study showed that South West students’ performance for the three years was largely poor. The result also showed that male students performed better than their female counterparts. It was recommended among others that the National Mathematical Centre, Nigeria should make preparatory textbooks and other materials available and accessible to participating students to get them well prepared and perform better in the Olympiads.

Gender as Determinant of Students Performance in Mathematics Periodic Tests and Terminal Examination in Federal Capital Territory Secondary Schools in Nigeria

The purpose of this study was to investigate the influence of students’ gender on their performances in mathematics periodic tests and terminal examination. The aim was to determine the contributions of students’ gender to performance of students in mathematics periodic tests and terminal examination. The study adopted an ex-post facto research design in which the researcher does not have direct control on the independent variables, since the manifestation had already occurred. It involves the collection of existing data. The target population for the study consisted of Junior Secondary School II (JSS II) students in Abaji Area Council of Federal Capital Territory, Abuja. 200 students were drawn from five (5) public schools through a multistage sampling technique. The researchers made personal contact with all the selected schools and collected the following items: Copies of the three continuous assessments in mathematics of 2nd term 2020/2021 academic session.The copy of terminal examination mathematics results of 2nd term2020/2021 academic session.The sex of the selected students. The result revealed that there was significant difference between the academic performance of male and female students in mathematics periodic Test 1 (t = 3.386, P < 0.05), Test 2 (t = 2.445, P < 0.05), Test 3 (t = 2.217, P < 0.05), Test 4 (t = 2.659, P < 0.05) and Terminal examination (t = 3.791, P < 0.05) at 0.05 level of significance. This was statistically significant at 0.05 level. The study established that students’ performance in mathematics periodic tests and terminal examination were affected by students’ gender. The study recommended that teachers should be gender sensitive and accommodating by taking into consideration individual differences in students’ rate of learning irrespective of gender.

3-dimensional surface magnetic susceptibility distributions with depth to investigate anthropogenic pollutants boundary in Abuja Metropolis

Changes in the magnetic susceptibility of topsoil, especially in urban areas, are greatly affected by the deposition of anthropogenic metallic dust arising from industrial activities, the burning of fossil fuels, car wear, and tyre abrasion. In this study, magnetic susceptibility measurements were carried out in vertical soil profiles of 30.0 cm depth from the surface at 10.0 cm intervals in about 431 locations within the Abuja metropolis with a view to investigate the penetration ability of magnetic pollutants in the ground. From the obtained data, 3-D surface contour maps were plotted for different depths. The results show a magnetic susceptibility decrease from the surface down the ground to the depth of 30.0cm; most of the recorded susceptibilities were of an anthropogenic origin rather than pedogenic activities. This indicates that the anthropogenic dust depositions are mostly a surface phenomenon and may therefore not pose a risk to groundwater aquifers and near surface wells

HUMAN-INDUCED IMPACT ON THE DISTRIBUTION AND DIVERSITY OF BENTHIC MACROINVERTEBRATES AND FISH FAUNA IN THE TROPICAL IKANG RIVER, NIGERIA

Tropski vodeni ekosustavi jugoistočne Nigerije obično se sastoje od močvara mangrova i obalnih šuma, a ugroženima su postale posljednjih šest desetljeća. Cilj ovog istraživanja bilo je utvrditi opseg i aktivnosti utjecaja čovjeka na kakvoću vode, te na distribuciju i raznolikost bentoskih makrobeskralježnjaka i riba u tropskoj rijeci Ikang. Uzorkovani su riječna voda, bentoski makrobeskralješnjaci i fauna riba, te su identificirani kako bi se stvorila baza referentnih podataka. Identificirano je dvanaest (12) vrsta bentoskih makrobeskralježnjaka iz dvije (2) skupine. Postaja 1 imala je najveću brojnost bentoskih makrobeskralježnjaka od 58 (35,65%), dok je postaja 3 imala najnižu brojnost od 52 (31,70%). Uca tangeri bio je najzastupljeniji bentoski makrobeskralješnjak s postotkom brojnosti od 28 (17,07%), dok su Dinocras sp., Macromia sp. i Gomphus sp. bili su najmanje zastupljeni bentoski makrobeskralježnjaci s postotkom zastupljenosti od 3,66%. Osim toga, identificirano je sedam (7) vrsta riba iz šest (6) porodica. Tijekom istraživanja najzastupljenija je bila porodica Claroteidae, dok je porodica Carangidae bila najmanje zastupljena. Temperatura rijeke imala je pozitivnu korelaciju s prodicama Carangidae i Mugilidae, negativnu s porodicom Clupeidae, dok nikakvu s porodicom Claroteidae. Ukupne otopljene čvrste tvari (TDS) pozitivno su korelirale s porodicama Carangidae, Mugilidae i Clariidae, dok je vodljivost pozitivno korelirala samo s prodicom Sciaenidae, a negativno s prodicama Carangidae, Mugilidae i Clariidae. Na brojnost i raznolikost bentoskih makrobeskralješnjaka i riblje faune općenito su utjecale fizikalne i kemijske karakteristike vode, dostupnost hrane te opseg ljudskih utjecaja i aktivnosti. Kako bismo osigurali održivu kvalitetu vode i očuvanje bioraznolikosti u ovom okolišu, potrebno je primjereno upravljati rijekom i okolnim ekosustavom.South-eastern Nigeria\u27s tropical water ecosystems typically consist of mangrove swamps and riparian forests, both of which have become endangered in the last six decades. The purpose of this research was to determine the extent of human-induced impact and activities on the effect of water quality on the distribution and diversity of benthic macroinvertebrates and fish fauna in the Tropical River (Ikang). The river\u27s surface water, benthic macroinvertebrates, and fish fauna were sampled and identified to create a database of reference information. Twelve (12) species of benthic macroinvertebrates from two (2) phyla were identified. Station 1 had the highest benthic macroinvertebrate abundance of 58 (35.65%), while Station 3 had the lowest abundance of 52 (31.70%). Uca tangeri was the most abundant benthic macroinvertebrate with a percentage abundance of 28 (17.07%), while Dinocras sp., Macromia sp., and Gomphus sp. were the least abundant benthic macroinvertebrates with a percentage abundance of 3.66%. In addition, seven (7) fish species from six (6) families were identified. During the study, the family Claroteidae was the most abundant, while the family Carangidae was the least abundant. The temperature of the river had a positive correlation with the families Carangidae and Mugilidae, a negative correlation with the family Clupeidae, and no correlation with the family Claroteidae. Total dissolved solids (TDS) correlated positively with the families Carangidae, Mugilidae, and Clariidae, while conductivity correlated positively only with the family Sciaenidae and negatively with the families Carangidae, Mugilidae and Clariidae. The abundance and diversity of benthic macroinvertebrates and fish fauna were generally influenced by the physical and chemical characteristics of the water, the availability of food, and the extent of human impacts and activities. In order to ensure sustainable water quality and biodiversity conservation in our environment, it is necessary to manage the river and the surrounding ecosystem appropriately
