Alternative Use of Achi, UKPO, and OFOR as Substitute to Standard Viscosifier
In Nigeria, drilling companies import a bulk of drilling fluid materials that they use to carry out their respective operations. This has been a major concern to oil and gas industries since these drilling fluid materials cannot be recycled, are highly expensive in terms of foreign exchange, are not environmentally friendly, not very effective, and non-biodegradable. This work presents an experimental investigation into the reliability of the use of local materials as a substitute to conventional viscosifiers. Local materials used in the analysis are Mucuna solannie (Ukpo), Brachystegia eurycoma (Achi), and Detarium microcarpium (Ofo). The results obtained from the experimental analysis show that they compared closely to the standard viscosifer formulated with Pac-R. The results showed that the density, specific gravity, pH, yield stress, Gel strength, Plastic Viscosity, and yield point of mud formulated from local materials compared favorably with that of the imported viscosifer. It was observed that an increase in concentration produced a better result. Hence, they could replace the Pac-R considering cost, cutting carrying ability, etc
Towards Transforming Osogbo into a Sustainable City, The Remote Sensing Perspective
This study has examined the impact of rapid urbanization on the sustainable development of Osogbo and demonstrated the use of remote sensing as a tool in achieving a sustainable city. Having identified urbanization in its entirety as a major determinant of whether or not a city will and can attain sustainability. Primary data through questionnaires administration was employed to obtain data on demography, occupation, waste management practices, etc, and three Landsat images (Landsat TM 5, ETM +7, and Landsat 8 OLI/TIRS) covering Osogbo for the years 1998, 2002 and 2017 respectively were analyzed into different land use land cover classes to demonstrate the impact of rapid urbanization on the study area over space and time serving as the major source of secondary data. The research revealed that, over the years there has been a shift from the vegetative type of land cover to other types of land use particular among which are settlement and commercial land use types leading to a considerable increase in urban area and a decrease in vegetation as evident in the analyzed satellite images and the questionnaire report. Based on the questionnaire report and field survey, there seems to be some positive change in Osogbo, especially in terms of waste management, road networks, and education facilities, which can be attributed to the state government’s effort in making the capital city more conducive for residents and befitting as a state capital, but the city can still not be considered as been on the path to sustainability. Being the administrative and commercial center of Osun state, the city keeps increasing in population and as agreed by the respondents, there is the danger of overcrowding, destruction of green areas to erect buildings, increasing rate of unemployment, deforestation, and other population-related issues. These don’t in any way portray Osogbo as a sustainable city or one in the making. Also, the city’s energy sector is still highly dependent on fossil fuels (petroleum), and the transportation system needs improvement to reduce the city’s contribution to the greenhouse gas effect
Detection of Class 1 Integron Among Klebsiella Species Isolated from Clinical Samples at No (1) Defence Services General Hospital (1000 Bedded)
Klebsiella species is commonly associated with serious nosocomial infections. Multi-drug resistant Klebsiella species isolates are becoming increasingly prevalent in the clinical and nosocomial environments. The high prevalence of Klebsiella infections is related to the ability of Klebsiella species to acquire and disseminate exogenous genes associated with mobile elements, such as plasmids, transposons and integrons. This study was conducted to find out the presence of class 1 integron and antibiotic susceptibility patterns of Klebsiella species from clinical specimens at No (1) Defence Services General Hospital (1000-Bedded). A laboratory based cross-sectional descriptive study was carried out from January to september, 2020. Identification and antimicrobial susceptibility testing of Klebsiella species was performed by VITEK 2 Compact Analyzer. Class 1 integrons were detected by conventional PCR. In this study, 110 Klebsiella species were isolated from various clinical specimens and most of the isolates were from medical ward (52.3%, 63 isolates). The highest rate of resistance was observed for ampicillin (100%) and Cefotaxime (97.3 %) whereas the lowest antibiotic resistance was to Amikacin (15.5%). Out of 110 Klebsiella isolates, 107 (97.3%) were multidrug resistant (MDR). Forty-four (40%) out of 110 Klebsiella isolates carried int1 gene and all these isolates were MDR. However, there was no association between multidrug resistance and integron positivity (p value = 0.273). The presence of class I integron genes among Klebsiella species highlights the continued monitoring is necessary for prevention of wide dissemination of integrons and infections by MDR pathogens
Fake Currency Detection Using Image Processing
Fake currency has always been an issue that has created a lot of problems in the world. Every country has been badly affected by this which has become a major problem. Moreover, it makes the domestic currency lose out its credibility in the global market. Thereby triggering adverse socioeconomic impacts. Counterfeit currency is also usually associated with terror financing. According to an RBI report, fake notes of the new Rs 500 series saw a 37% rise in 2019-20, and there was a fall in circulation of Rs 2000 notes. The increasing technological advancements have made the possibility of creating more counterfeit currency. Fake currency has always been an issue that has created a lot of problems in the world.

Time Expansion at the Interface of Organic Metallic Surfaces
Giant magnetization of polyalanine monolayers on gold observed in recent years along with unusual large spin selectivity, the potential of the film, and its temperature dependence are all explained in the context of vacuum polarization at the gold-monolayer interface. The enhancement is directly related to the fine structure constant, a and involves a change in basic physical parameters including changes in the permeability of the vacuum and in the local zero point energy (ZPE) of the gold-monolayer interface. Formation of an ordered state by the self-assembly process and the interaction of the monolayer with the gold plasmons form a new state of matter that can interact strongly with the ZPE
Health Risk Factors and Refugee Children in Bangladesh: A Study on Rohingya at Kutupalong Camps
In the Cox's Bazar refugee camps, around 855,000 Rohingya people live, with 54 percent of them being children. In Myanmar, these children were denied access to adequate healthcare, immunizations, food & nutrition, hygiene, and education. Since August 2017, when the Rohingya were forced to flee from Myanmar to Bangladesh due to the Myanmar military's brutality, they have become more vulnerable. Children were vulnerable to hunger and various infectious diseases as a result of the fighting and displacement, which posed serious health hazards. The numerous health risk factors of the children were analyzed in this study in order to provide a picture of the refugee camp.
Method: In December 2017, a questionnaire was used to assess the shelter and camp environment, food and nutrition, WASH knowledge and practice, vaccination and immunisation, medication and supplements, and education of 120 parents of Kutupalong camp no 4, OO zone.
Result: The health of 29% of the children was better than a year before, while 68 percent of the children had the same result as the previous year. Breakfast and supper were consumed by 96.67 percent of the children, and 80.8 percent were fed three times lunch and supper, with 63 percent agreeing that the camp setting was not ideal for their growth. 61 percent of families could provide enough water for their children using the water containers provided by various NGOs (Non-governmental Organisations). Despite the fact that the water sources are not close to their homes, 98.3 percent of families use tube well water. Only 49.2 percent of parents said the latrines had enough water for bathing and cleaning, while 29.2 percent said they had adequate lighting and were in their suitable placements. After using the restroom, 66.7 percent of children used soap, 16.7% used soil or ashes, and the rest used nothing. Vaccinations had been given to 91.7 percent of Rohingya children. In Bangladeshi refugee camps, 56.2 percent of Rohingya children were educated by learning centers run by various NGOs and Maktabs (Muslim kids were taught Quran in masjids).
Limitations: This report has relatively limited data that does not provide a comprehensive picture of the children's camp situation.
Conclusion: Based on the findings of the study, the camp's status may be improved if the children and their families were given good WASH knowledge and introduced to the WASH awareness programme, proper water supply and sanitation, and health care as needed
Unified Theory of Gravity and Electromagnetism: Classical and Quantum Aspects
A unified classical theory of gravity and electromagnetism with a torsion vector 0, proposed by S N Bose in 1952, is introduced. In this theory, the torsion vector acts as a magnetic current and it is shown that (i) the electromagnetism is invariant under continuous Heaviside–Larmor transformations and (ii) the electric and magnetic charges are topologically quantised, satisfying the Dirac quantisation condition, without implying any Dirac string provided is curl-less

Molecular Sub-typing of Diffuse Large B-cell Lymphoma
Diffuse large B-cell lymphoma (DLBCL) is the most common form of Non-Hodgkin Lymphoma (NHL) in adults. Affecting nearly 7 out of every 100,000 people in the United States annually, this hematogenous neoplasm is known for its aggressiveness and rapid development. Being the most common NHL, it has been divided into several subgroups based on pathogenesis and treatment methods. In particular, subtypes such as germinal center, activated B-cell-like, and primary mediastinal diffuse large B-cell lymphomas have been divided by their uniqueness of pathology at the cellular level. Knowing the numerous cytokines, inflammatory markers, and other microcellular processes that these lymphomas disrupt can help target an effective therapeutic at the disease
