CenterYou: Android privacy made easier the Cloud Way
No full textThe Smartphone industry has expanded significantly over the last few years. According to the available data, each year, a marked increase in the number of devices in use is observed. Most consumers opt for Smartphones due to the extensive number of software applications that can be downloaded on their devices, thus increasing their functionality. However, this growing trend of application installation brings an issue of user protection, as most applications seek permissions to access data on a user’s device. The risks this poses to sensitive data are real to both corporate and individual users. While Android has grown in popularity, this trend has not been followed by the efforts to increase the security of its users. This is a well-known set of problems, and prior solutions have approached it from the ground up; that is, they have focused on implementing reasonable security policies within Android’s open-source kernel. While these solutions have achieved the goals of improving Android with such security policies, they are severely hampered by the way in which they have been implemented them. In this work, a framework referred to as CenterYou is proposed to overcome these issues. It applies pseudo data technique and cloud-based decision-making system to scan and protect Smartphone devices from unnecessarily requested permissions by installed applications and identifies potential privacy leakages. The current paper demonstrated all aspects of the CenterYou application technical design. The work presented here provides a significant contribution to the field, as the technique based on pseudo data is used in the actual permissions administration of Android applications. Moreover, this system is user and cloud-driven, rather than being governed by over-privileged applications.</p
Effect of fresh and fermented camel milk and colostrums on body weight and blood glucose level in alloxan-induced diabetic rabbits
No full textTo study the effect of fresh camel milk, fermented camel milk and colostrums on blood glucose levels 30 Alloxan-induced diabetic rabbits were taken. Diabetes was induced in rabbits using Alloxan, the diabetic rabbits were then treated with fresh camel milk, fermented camel milk and colostrums as well as insulin for 60 days. The results demonstrated that the body weight of rabbits treated with camel milk and its derivatives found to be kept within the accepted body weights range of 1.8- 2.5 kg. The lowest serum glucose levels were recorded by Group 1 (control), Group 3 (diabetic-treated with colostrums), Group 4 (diabetic-treated with milk), Group 5 (diabetic-treated with gars) and Group 6 (diabetic-treated with Insulin16 mg/kg body weight daily for 8 weeks) and the levels found to be within the normal level range of 75- 140 mg/dl, the highest level of serum glucose level was recorded by Group 2 (diabetic-non supplemented) and it was higher than the upper limit of the normal range. </p
Potential effects of genetic polymorphism on anesthesia use for COVID-19 infected patients at intensive care unit
No full textBackground: New coronavirus disease is considered one of the most widely spreading viral infections all over the world. Increased numbers of severe COVID-19 cases are growing up. Severe cases require ICU mechanical ventilation and hence anesthesia requirement. Aim: Reviewing of different genetic polymorphisms which might affect patient clinical response, safety and tolerability to different types of anesthesia used in severe COVID-19 patients requiring mechanical ventilation. Main body of the abstract: Severity of COVID-19 infection resulted from cytokine storm that leads to Acute Respiratory Distress Syndrome (ARDS) contribute in ICUs mechanical ventilation and anesthesia. Genetic polymorphisms showed to contribute in wide variation in anesthetic responses. Different polymorphic genes of RYR1, CACNA1S, MTHFR, OPRM1, ABCB1, CYP2B6 and others, play a main role in such variations. Different types of anesthesia as sevoflurane, midazolam, suxamethonium, nitrous oxide, fentanyl, and propofol showed altered pharmacokinetics and/or dynamics leading to a lack of anesthetic effect and incidence of life-threatening adverse effects as malignant hyperthermia, myocardial infarction, dyspnea, and others.Short conclusion: Genetic screening is a serious step to take into consideration to identify genetic polymorphic types that may alter the anesthetic effect in ICUs ventilation. Besides, it will avoid possible adverse effects and different sedation response variations. Sevoflurane, Fentanyl, and propofol can be taken into consideration as a safe choice for use in ICUs taking into consideration genetic polymorphic variants. </p
Application of Genetically Modified Organism (GMO) crop technology and its implications in modern agriculture
No full textGenetic modification entails incorporating DNA into an organism’s genome as well as putting new DNA into plant cells in order to create a genetically modified plant. Chemicals are poured into plants to improve product sizes and productivity in genetically modified organisms (GMOs), a type of clinical farming. The goal of genetic modification is to provide enhanced features to plants by altering their genetic makeup. This is done by inserting a novel gene or gene into the genome of a plant. Flavr Savr tomatoes were the first genetically modified plants, and they were modified to delay the ripening process, preventing tenderness and rot. Complete crop production increased significantly after the introduction of GM crops at some point during the generation; some of these increases may be due to GM technologies and crop protection advances that have been made possible, despite the fact that GM crops adopted so far are not crop yields. GMOs gain humanity when they are utilized for purposes like improving the availability and quality of food and hospital therapy, as well as contributing to a cleaner environment. If employed correctly, they have the potential to improve the economy without inflicting more harm than good, as well as gain from its ability to alleviate hunger and sickness around the world. However, the full potential of GMOs cannot be identified without thorough research and attention to the dangers associated with each new GMO on a particular scenario basis. Improved resistance to disease and pests can be achieved by genetic modification. It may enable the production of more nutritious staple plants that provide key micronutrients that are frequently lacking in the diets of poor people. As a result, the purpose of this review was to assess the deployment of genetically engineered crops and their effects on modern agriculture progress.</p
The nature of post-occupancy modifications of selected low-income housing estates in Nigeria
No full textThis paper aims to evaluate the nature of post-occupancy modifications of selected income housing estates in Nigeria. The research adopts both the quantitative and qualitative approaches and is essentially survey-based. Therefore, the research population is all housing units of low-income public housing estates in Owerri Metropolis. A simple random technique was further adopted to select five low-income housing estates within the low-income group for this study. Participants of this study were further sampled and selected based on the following requirements and eligibility criteria - they must be residents in the residential estates under study; they must be household heads (or their representatives) of the buildings in the selected housing estates and the building must have been in existence for over ten years (which is enough time for modification to have taken place). The data were collected through the use of a structured questionnaire and field observations, and analysis of this data relied on the computer-based statistical software called STATA 13.0. Results were presented and discussed, pinpointing the nature of post-occupancy modifications in the five selected low-income housing estates. The results further show various kinds of modifications (addition of rooms, alteration of site arrangement, alteration of fence design, alteration of roofing pattern, addition of shop spaces, change of use, and outright total modification) have taken place across the five housing estates studied.</p
Performance of residential property investment returns in an emerging metropolitan area. The awareness, use and gender inequality
No full textThis study assessed the performance of residential property investment returns. To ascertain the awareness, use, and gender inequality in the usage of residential performance data by investors. The paper focuses on risk-return features of the tenement, two and three-bedroom property for investment purposes, in order to improve the understanding of the property market mechanism in Kano metropolis, Nigeria. Unraveling empirically risk-return features of residential property in the metropolitan area is unclear hence the speculative decision on residential investment is widespread. Quantitative research was employed using a questionnaire survey to obtain primary data on annual rental and capital values of residential properties from branch managers of estate firms. This data was afterward transformed into total returns and put to Phillip-Perron unit root test (stationarity). The study utilized both descriptive and inferential statistical techniques for analysis. Findings from the study show that total returns for residential property range from 6.99% to 14.44% with risk-return ranging from 20.92% to 51.54% within the property market, Badawa/GRA property has the lowest risk features hence the most secured location for residential investment, the paper also unveils that gender inequity in the usage of residential property investment performance data is high against women. It is on these findings that the study recommended Badawi/GRA property market for risk-averse investors, persistent sensitization program and incentives (reduction in service charge) targeting women in the property market is encouraged.</p

Clinical features of Rheumatoid Purpura in adults
No full textIntroduction: Rheumatoid purpura is a systemic vasculitis of small vessels that is more common in children than in adults. The aim of our study was to revise the characteristics of rheumatoid purpura in adults.Methods: We conducted a retrospective descriptive and analytical study [June 2016 - June 2021], including all the patients hospitalized in the dermatology department of Ibn Rochd University Hospital for rheumatoid purpura. We first described the characteristics of adult patients aged over 18 years old, and then we compared them to those of the children (<18 years old) to determine the clinical features in adults. Results: A total of 18 adults (15 women/3 Men) and 9 children were collected. Adults had a mean age of 48 years [27-66 years]. Vascular purpura was constant, complicated by necrosis in 12 patients, bullae in 6 patients, and ulceration in 2 patients. Joint involvement was present in 16 patients. Ten patients presented digestive signs: epigastralgia (n= 4), abdominal pain (n= 8), and rectal bleeding (n= 2). Cutaneous biopsy showed leukocytoclastic vasculitis in all patients with IgA and C3 deposition in 13 patients. Renal involvement was present in 6 patients. After comparison with the children group, the particularities in adults were the absence of previous drug intake (p= 0.009), absence of pruritus (p= 0.009), presence of bullae (p= 0.05), presence of severe digestive involvement (p= 0.033), joint involvement (p= 0.003), and presence of anemia (p= 0.017). Conclusion: Rheumatoid purpura in adults is characterized by its severe clinical features.</p
Analysis of secondary data: Considerations revisited
No full textIn a recent publication, we discussed the benefits and cautions of using secondary data analyses in research on lifestyle and health behavior [1]. We provided some guidelines about the use of secondary data in terms of the contributions that can be made and at the same time considerations necessary in using data that are collected by someone else. The use of secondary data to explore social and health issues results in being able to provide information about important issues in a timely fashion. Secondary data can answer two types of questions: descriptive and analytical [2]. Hence, the information can be used to describe events or trends or it can be used to examine relationships among variables cross-sectionally or longitudinally. </p
Monkey menace in Kwa Vonza/Yatta Ward, Kitui County, Kenya: Threat to food and nutrition security and sustainable livelihoods
No full textSince time immemorial, farmers in the arid and semi-arid lands in Kitui County have had many challenges in attaining food and nutrition security. This is largely attributed to inadequate rains, crop diseases, pests, and crop damage by wild animals among others factors. However, the monkey menace and its threats to food security and sustainable livelihoods in Kitui County are not documented. On this basis, a socio-economic survey was carried out in Kwa Vonza/Yatta ward, Kitui Rural constituency in Kitui County to establish i) the extent of damage by monkeys in the ecosystems ii) socio-economic impacts caused by monkeys iii) mitigation measures employed to control the monkey menace in Kitui rural constituency. The socio-economic survey, using one hundred and fifty (150) respondents, revealed that 65% of the respondents indicated that the monkey menace was a threat to food security, and human and livestock life. The respondents noted that monkeys damage their crops (cereals, fruits, and vegetables) on the farm, kill kids of goats and lambs of sheep, and damage food in stores and kitchens. In extreme cases of dry spells, 25% of the respondents indicated the monkeys caused physical injuries to children when the monkeys are looking for food in their homesteads. The respondents felt that the government, through Kenya wildlife services, should intervene to control the monkey population in the hilly habitats for the farmers to have gainful agricultural production and sustainable livelihoods.</p
