TEGDroid: Test Case Generation Approach for Android Apps Considering Context and GUI Events

The advancement in mobile technologies has led to the production of mobile devices (e.g. smartphone) with rich innovative features. This has enabled the development of mobile applications that offer users an advanced and extremely localized context-aware content. The recent dependence of people on mobile applications for various computational needs poses a significant concern on the quality of mobile applications. In order to build a high quality and more reliable applications, there is a need for effective testing techniques to test the applications. Most existing testing technique focuses on GUI events only without sufficient support for context events. This makes it difficult to identify other defects in the changes that can be inclined by context in which an application runs. This paper presents an approach named TEGDroid for generating test case for Android Apps considering both context and GUI Events. The GUI and context events are identified through the static analysis of bytecode, and the analysis of app’s permission from the XML file. An experiment was performed on real world mobile apps to evaluate TEGDroid. Our experimental results show that TEGDroid is effective in identifying context events and had 65%-91% coverage across the eight selected applications. To evaluate the fault detection capability of this approach, mutation testing was performed by introducing mutants to the applications. Results from the mutation analysis shows that 100% of the mutants were killed. This indicates that TEGDroid have the capability to detect faults in mobile apps

The Way forward for Community-Based Health Insurance Scheme in Funding Health Care among the Rural Communities of Sokoto State, Nigeria

Health  care financing in most of Sub-Saharan Africa is based on out-of-pocket payment from the rural dwellers.”This out-of-pocket payment has caused a lot of health troubles such as premature deaths, maternal problems, deficiencies in health issues in Sub Sahara countries. This report examines issues pertaining to health financing in Nigerian rural areas in order to encourage people in SSA to implement “Community-Based Health Insurance Scheme in the rural regions.” “It’s been significant because it offers a chance for the citizenry to be out of poverty as a result of high money paid whenever they are assessing health care through out-of-pocket payment at the point of service delivery. “This schema is a raw area of health financing in the developing countries supported by the World Health Organization (WHO), World Bank (WB) and the International Labor Organization (ILO) among others.” Few of the SSA countries like Ghana, Mali, and Burkina Faso are doing well using the scheme to finance health care delivery in the rural regions. “In Nigeria, this concept of community-based health insurance plan is a new development. Thus, an attempt should be attained to create consciousness about this commendable project.” The management of the CBHIS should focus on the rural dwellers on one hand, and government should provide enabling laws on the other.

Traditional bone setting: an avoidable cause of major limb amputations

Background: Despite the availability of modern health care services, patients in Nigeria still seek treatment by traditional bone setters. One of the major complications of this type of native fracture treatment is limb gangrene necessitating amputations. The objective of this study was to determine the role of traditional bone setting in major limb amputations.Methods:  This retrospective study was carried out at a government orthopedic referral hospital. The study involved all patients who underwent major limb amputation between January 2015 and December 2019 in our center. Data were retrieved from medical records and operation registers. Information regarding age, sex, indications and levels of amputation and complications were studied.Results: During the study period; of the 297 major limb amputations performedd, 194 (65.3%) were due to traditional bone setting. The median age of the patients was 11.0 years (1 to 45 years) and the interquartile range was 10 years. Majority of the patients 86 (44.3%) affected were children less than 10 years of age. Male were more affected than female (M:F=1:2). Lower limb is more affected than the upper limb. The commonest amputation done was below knee amputation in 79 (40.7%) of cases. The commonest complication was surgical site infection which occurred in 32 (16.5%) patients.Conclusions: Traditional bone setting is a leading cause of major limb loss especially in children

Comparative analysis on the effect of heavy metals: a case study of selected states in Nigeria

In the toxicological aspect, uncontrolled amount of heavy metals is deadly, to the environment and its inhabitants. To complicate issues, reviewed work has revealed that technological advancement is one of the key sources of heavy metals. This can lead to outbreak of diseases, decrease of life span, cancer, and other related effects. Providing sustainable environment, the concentration of these metals need to be periodically regulated. This research studies the effect of some selected heavy metals (Fe, Cd, Cu, Ni, Cr, Pb, Zn and Mn) in Kano State Nigeria, using Atomic Absorption spectroscopy (AAS). The results were compared with other related work conducted in some states across Nigeria (Akwa Ibom, Kwara, Kaduna, and Bauchi States) and standard international values (WHO, FAO, SEPA and US EPA). The parameters analysed were; Concentration, Bioaccumulation (Plant concentration factor –PCF), Transfer factor (TF), Daily Intake of Metals (DIM), and Health Risk Index (HRI). Statistical package (SPSS) was used, to establish the relationship between these metals in all the sites. The result showed that there were substantial absorption of these metals by the plants and the consumers. Children were more exposed than adults in terms of DIM and the HRI. The comparison showed sequential order in the parameters investigated. All the biological samples exhibited Phytoremediation quality with the TF>1, this will aid in having sustainable environment to the resident and citizen of the state in particular and the nation in general, as well as serving as an impetus for the initiation of safe comprehensive remedy of the subject matter. The PCF for all the samples varied across states and plants.Keywords: AAS, Adults, ANOVA.

Association Between Glomerular Filtration Rate And Body Mass Index Among Orthopaedic Patients In Kano-Nigeria

Any association between body mass index and kidney disease has so far proved inconclusive. Therefore, this study is aimed to provide association between glomerular filtration rate and body mass index among orthopaedic patients. A total of sixty (60) patients irrespective of gender were recruited. Weight and height were measured prior to the sample collection. A structured questionnaire was administered to obtain the demographic data of the subjects. Blood samples were collected from each patient by venepuncture from the antecubital vein of the forearm using disposable syringes. Serum creatinine was determined by method of Rosano et al. Body Mass Index and Glomerular Filtration Rate (eGFR) were calculated using creatinine-based equation of Modification of Diet in Renal Disease. Mean BMI was found to be higher in females (25.48±5.65) than their male counterparts (21.44±4.52), while eGFR was found to be higher in males (184.14±53.23) than in females (152.06±32.71). Subjects with eGFR ≥60 were observed to be more frequent (98.30%); normal weight individuals had higher frequency (48.33%). Positive correlation exists between BMI and eGFR in males whereas negative correlation was found in females which indicates association between body mass index and kidney function is gender related

Enhanced caffeine degradation by immobilised cells of Leifsonia sp. strain SIU

In a previous study, we isolated Leifsonia sp. strain SIU, a new bacterium from agricultured soil. The bacterium was tested for its ability to degrade caffeine. The isolate was encapsulated in gellan gum and its ability to degrade caffeine was compared with the free cells. The optimal caffeine degradation was attained at a gellan gum concentration of 0.75% (w/v), a bead size of 4 mm diameter, and 250 beads per 100 mL of medium. At a caffeine concentration of 0.1 g/L, immobilised cells of the strain SIU degraded caffeine within 9 h, which is faster when compared to the case of free cells, in which it took 12 h to degrade. The immobilised cells degraded caffeine completely within 39 and 78 h at 0.5 and 1.0 g/L, while the free cells took 72 and 148 h at 0.5 and 1.0 g/L, respectively. At higher caffeine concentrations, immobilised cells exhibited a higher caffeine degradation rate. At concentrations of 1.5 and 2.0 g/L, caffeine-degrading activities of both immobilised and free cells were inhibited. The immobilised cells showed no loss in caffeine-degrading activity after being used repeatedly for nine 24-h cycles. The effect of heavy metals on immobilised cells was also tested. This study showed an increase in caffeine degradation efficiency when the cells were encapsulated in gellan gum

Two decades of neuroscience publication trends in Africa.

Neuroscience research in Africa remains sparse. Devising new policies to boost Africa's neuroscience landscape is imperative, but these must be based on accurate data on research outputs which is largely lacking. Such data must reflect the heterogeneity of research environments across the continent's 54 countries. Here, we analyse neuroscience publications affiliated with African institutions between 1996 and 2017. Of 12,326 PubMed indexed publications, 5,219 show clear evidence that the work was performed in Africa and led by African-based researchers - on average ~5 per country and year. From here, we extract information on journals and citations, funding, international coauthorships and techniques used. For reference, we also extract the same metrics from 220 randomly selected publications each from the UK, USA, Australia, Japan and Brazil. Our dataset provides insights into the current state of African neuroscience research in a global context

African neuroscience on the global stage: Nigeria as a model

Effect of Heavy Metals and Other Xenobiotics on Biodegradation of Waste Canola Oil by Cold-Adapted Rhodococcus sp. AQ5-07

The Antarctic is generally considered to be one of the most pristine areas in the world. However, both long and short-range pollutants are now known to be present in the Antarctic environment. Canola oil is an example of a polluting hydrocarbon that can be accidentally released into the Antarctic environment in oil wastewater treatment plants. The Antarctic soil bacterial strain Rhodococcus sp. AQ5-07, known to be capable of using waste canola oil (WCO) as its sole source of carbon, was tested for its ability to degrade canola oil in the presence of different heavy metals and xenobiotics. Rhodococcus sp. AQ5-07 was grown on minimum salt media containing different heavy metals (Zn, Co, Ni, Ag, Pb, Cu, Cr, Hg, Cd and As), xenobiotics (acrylamide and phenol) supplemented with 3% WCO. Three out of the 10 heavy metals tested (Hg, Cd and Ag) led a significant reduction in canola oil degradation at a concentration of 1 ppm. The IC50 values of Hg, Cd and Ag were 0.38, 0.45 and 0.32 ppm, respectively. The strain could also withstand 10 mg/L acrylamide, 50 mg/L phenol and 0.5% (v/v) diesel. This study confirmed the ability of Rhodococcus sp. AQ5-07 to degrade canola oil in the presence of various heavy metals and other xenobiotics, supporting its potential use in bioremediation of vegetable oil and wastewater treatments in low temperature environments
