In spite of the increased use of electronic gadgets which has proportionately increased the accumulation of e-waste, E-waste in Kisumu is informally managed and it is not known whether the informal management of e-waste is sustainable. The purpose of this study was to establish management systems of 3R on sustainability of e-waste management in Kisumu City, Kenya. The research adopted a descriptive survey design and data collected using questionnaires, interview, Focus Group Discussions and observation from a sample size of 425 respondents out of a target population of 148,494 households while analysis involved descriptive statistics. The study concludes that the current e-waste management is not sustainable because: there is no monitoring of the volumes of e-waste generated making it difficult to plan for its disposal, there is a high turnover of e waste at the rate of 78% within 5 years without a corresponding mechanism for reducing, recycling and reusing, policy formulation and enforcement by relevant government ministries remains weak and investors and NGOs are unwilling to invest in this area due to expensive capital infrastructure and technology inadequacy. The study recommends that NEMA e-waste management guideline 2010 should be enforced to ensure proper reduce, reuse, recycling and disposal besides amendments to Public Health Act (1962), Urban Areas and Cities Act No.13 of 2011 (Cap. 265) to comply with the NEMA guideline. MIC should enforce their requirement for Extended Producer Responsibility on ICT Actors. The relevant ministries and the civil society need to create awareness of e-waste and its safe handling. NEMA and the County Government should offer incentives to interested investors. KEBS should train expertise in forensic audit of hazardous components included in electronic equipment’s and discourage importation of such substances.

Farmers highly depend on chemical pesticides in recent farming practices to ensure expected yield is met, and organophosphates pesticides has been the common pesticides used on fruits and vegetables, this pesticide’s instruction are not dully followed by farmers. Thereby the possibility of residue of these pesticides will continually be a concern. Acceptable daily intake values are being set by WHO and Food and Drug Agency using Cordex, and also the maximum residual limits of each pesticides in each fruit and vegetables to ensure safe level is maintained. But the farmers might not be informed about the possibility of the dangers of long-term exposure to the pesticide. This study shows the concentration level of organophosphate residue in fruits eaten almost every day in relation to the health risk values. The concentration ranges from Fenamiphos with a mean concentration of 0.08mg/kg showing the lowest while bromophos-methyl showed a mean concentration of1.136mg/kg as the highest mean concentration followed by azinfos-methyl with a mean concentration of 1.056mg/kg, then Chlorpyrifos with mean concentration of 1.046mg/kg. Bromophos-ethyl was only detected in tomatoes and onions, Etrimfos was not detected in carrot and carrot has the least pesticides summation of the detected pesticide while garden egg sample shows the highest concentration summation followed by tomato, a daily consumed vegetable/fruit in the southern part of Nigeria. It also revealed that the health risk index for children is of concern than other population therefore cooking these vegetable and fruits is recommended to greatly lower the residues.

With the current trend and challenges of built-up swamp, many urban centres are experiencing consistent flooding and food insecurity causing huge damages and losses. The aim of the study was to analyse the implications of swampy development and the concern before the contributors of physical development in Nigeria. It explores the institutional arrangement for swamp management, planning measures that have been undertaken to reduce non-scientific development and management of swamplands, and possible ways to enhance the application of urban planning to reduce built-up swamp and management. However, the strength of physical planning in mitigating the development of swamp is well recognised. Also inadequate plans and poor enforcement makes development of swamp preparedness, response and recovery laughable hence resilience is frail .This study therefore set out to disentangle pertinent land uses that vanished swampland in Port Harcourt, ascertain the pattern and consequences of the encroachment in to swampy land. The research employed structured questionnaire techniques for data collection while Pearson product moment Correlation coefficient and mathematical percentage (MP) were the analytical tools used. The findings show that transportation land use (r = .262 p>.05), industrial land uses (r = .211 p>.05), residential land uses (r = .358 p>.05) commercial (r = .222 p>.05) and institutional were the significant factors for sprawling and by extension the development of swampy land in Port Harcourt urban space. In addition, the result also shows that the loss of food security (23%), recreation (11%), education and research services (15%), tourism/recreation (17%), open space and aesthetics (17%) cultural value (17%) are the major effects. The study concluded with recommendations that town planning board, authorities and registered town planners in consultancy services should advice state government on the risk and challenges of buildings on swamp regions and blockage of water ways of Port Harcourt Nigeria.

Surety bonds are of ancient times dating back to 2750 BC when a farmer who was offering services to a king, when not able to fulfill his duties hired another farmer to do the duties on his behalf and share the proceedings equally, a local merchant acted as surety and effected the compliance of the second farmer to the agreement. Suretyship grew up steadily over years and has today taken root in many business transactions requiring guarantors. In Construction projects, surety bonds are fundamental as construction projects are a risky business and at times referred to as a war fare. Apart from mobilization of materials and labor there is usually a divergence between project teams. The cause of divergent views between the project owner, principal contractor, sub contractors and the architect arrive from the payments allocations for all the concerned in the construction project. There is high entry new firms into construction ventures in Uganda, an investment that is fragile by nature of operations which is motivated the need for creating awareness on construction bonds that are vital for all parties involved in the construction project. This paper aims to craft knowledge on surety bonds /construction bonds to the novice construction companies getting aboard of the construction industry in Uganda. The study applied literature review, generalizations and systemization methods to diffuse the concept of construction bonds to the novice construction contractors as they enter the volatile construction business particularly in Kampala, Uganda.

Public health services in Indonesia are managed in a territorialism approach that limits services to a specific administrative area. Refferal system in health care sets primary health facilities to each citizen and limits crossborder services. The absence of primary health care in Glagaharjo border settlement and the limitation of crossborder services created barriers for universal health care in rural provincial border settlements. Interruptions in providing services to borderland communities were a major problem with the system during the era of good governance. Informal crossborder services involving changes in health-care administration came as a viable option for ensuring universal health-care services. This paper examines the process of crossborder primary health service delivery by Pustu Panggang, Central Java Province, to communities in Glagaharjo, Daerah Istimewa Yogyakarta Province, sharing provincial borderline. Data was gathered through in-depth interviews with local officials and stakeholders. Using the compare and contrast technique, the concepts of good governance and cross-border health services are compared and contrasted. Thefindings shows that informal acts including exceeding-authority decision making, ignorance, and other forms of misconducts come as the impromptu strategy to keep primary care available to those in need. As Covid-19 pandemic unfolded, informal acts save community from the lack of access to primary healthcare due to the cost of formal arrangement.

The study on settlement pattern, gas production and rate of degradation of putrescibles was investigated in this study from a prototype landfill in Federal University of Agriculture Makurdi-Nigeria using proposed water balance model. Fresh putrescible were collected from the university community to fill the single celled prototype landfill and allowed to degrade under natural condition for 50 days. Principal leachate and gas generation were recorded in-situ while other parameters were obtained from the waste settlement. Moisture content and pH variation were observed in a typical cell/bed (depth 60cm) during phase I and phases II of the experiment. A uniform settlement was recorded as a drop in height of the substrate column and maximum settlement was attained after 40 days. Field capacity decreases with waste volume and time. TOC and Gcell values of 2.5 and 2.7 respectively were established insitu for determination of the time rate of degradation. The time rate of degradation of putrescibles from the study is described as first order polynomial function (R² = 0.9866) with respect to FC but expressed as an exponential function in terms of height and wet weight of substrate ( R² = 0.9505 and R² = 0.9943 respectively).

The study was conducted to find the effects of collaborative learning on gender groupings in the mathematics performance of Bachelor of This study conducted a techno-economic comparative analysis of gas monetization technologies (Liquefied Natural Gas (LNG) and Gas to Liquid (GTL)) using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). In the course of the study, the pros (strengths) and cons (constraints/limitations) of the different gas monetization options were discussed, and the economics and technical viabilities of LNG and GTL were ascertained. Technically, five attributes/criteria (volume, distance, cost, time and environmental impact) were considered. From the TOPSIS analysis and results, the technically best technology considering volume, distance, cost, time and environmental impact was GTL with a score of 0.505. This LNG had a score of 0.495. From the analysis, the GTL performed better under the most significant criteria (cost and environmental impact), it also performed better than LNG under time of delivery. Whereas, the criteria where LNG performed better (volume and distance), their weights are not too significant to make it emerge ahead of GTL as a better technology technically. Hence, from the study findings, it can be deduced that GTL performed better technically than LNG.

Background: Bacteria infection of the urinary tract, also known as “Urinary tract infections (UTIs)” are among the most common bacterial infections of humans. Uncomplicated urinary tract infections can be easily treated with antibiotics; however, there is a growing resistance to conventional antibiotics. This has also been reported among bacteria associated in co-infection of urinary schistosomiasis and bacteriuria. Objective: To assess the antibacterial efficacy of aqueous and ethanol extracts of Azadirachta indica and Syzygium guineense leaves against bacteria associated with urinary schistosomiasis. Methods: Fresh leaves of A. indica and S. guineense were air dried and extracted using sterile distilled water and ethanol. Phytochemical constituents of A. indica and S. guineense leaves were elucidated using standard techniques. Antibacterial assay, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the plant extracts against; bacteria isolated from urine samples with single infection of bacteriuria, bacteria isolated from urine samples with co-infection of urinary schistosomiasis and bacteriuria, and typed bacteria were also determined using standard methods. Results: Qualitatively, saponin, tannin, flavonoid, steroid, terpenoid and glycoside were present in all the plant extracts, while alkaloid and phlobatannin were absent in the extracts. Quantitatively, terpenoid was the highest bioactive compound in aqueous extract of A. indica (25.15 ± 0.04) and ethanol extract of S. guineense (51.16 ± 0.03), while saponin was the highest in the aqueous extract of S. guineense (72.09 ± 1.67) and ethanol extract of A. indica (220.82 ± 0.64). The MIC of the various plant extracts against all the isolates and typed bacteria ranged from 6.25 mg/mL – 12.5 mg/mL, while the MBC ranged from 6.25 mg/mL – 25 mg/mL. Conclusion: This study revealed the antibacterial candidature of A. indica and S. guineense on Gram positive and Gram-negative bacteria isolated from urine.
