Published: December 2023

Aims: Small and medium enterprises (SMEs), create jobs and contribute to GDP but SMEs in Kilifi County are facing stagnation and high failure rate. This study set out to test three hypothesis i.e. process innovation has no significant effect on financial performance of SME’s, product innovation has no significant effect on financial performance of SME’s & Structured innovation has no significant effect on the financial performance of SME’s. The study is anchored on Theory of Technology Acceptance Model (TAM), Diffusion of innovation Theory and Kane's Theory of Innovation.
Study Design: The study employed explanatory research design with use of both qualitative and quantitative data approaches.
Place and Duration of Study: The study was carried out in the year 2021/2022 in Kilifi County in Kenya.
Methodology: From a target population of 496 registered SMEs, a Sample size of 216 SMEs was drawn using simple random sampling with use of self-administered questionnaires with both open and closed ended questions collecting data from managers/owners of the SMEs.
Results: Correlation results indicated that innovation (product, process and structural) are significantly associated with financial performance. Regression results revealed existence of a significant effect of each innovation on Financial Performance; Business Structural Innovation (B=.106, p= .001), Process innovation (B=.289, p=.003) and Product innovation (B=.143, P<.001).
Conclusions: A key finding is that only one in every five SMEs in Kilifi are past their 8th birthday. Business innovation has the highest variability suggesting most of the SMEs configure their businesses to market needs. Despite business innovation being low in SMEs, it is the most yielding when it comes to its effect on financial performance. Compared to business and process innovation, product innovation has least differences among the SME. It is conclusive that innovation among the SMEs is still low but the innovation-pursuing SMEs are also performance leaders.

Soil-transmitted helminths (STHs) diseases are among the group of Neglected Tropical Diseases (NTD). STHs infections are a significant public health problem globally with children being the most affected group. This study aimed to assess the knowledge, attitude and practice in relation to predisposing factors and preventive measures for STHs among children 4 to 15 years in Mutegene community.
It was a cross-sectional study, involving 250 school children of both sexes. A systematic random sampling method was used to collect data. Basic demographic data was obtained from the class registers. A structured questionnaire was used to collect information on personal bio-data, characteristics of their home and school environment in relation to helminthes transmission and prevention. Data was analysed using SPSS version 21 and Chi-square test.
The results showed that 44.4 % (n=109) of the participants had good knowledge of parasitic worms, and 62.0 % (n=155) of the participants knew how to avoid getting infected with worms. Soil-transmitted helminth infection was present in Mutengene community with an overall prevalence of 3.6% and the species present included A. lumbricoides, T. trichiura, and hookworms. Participants who indicated that they played out-doors had the highest prevalence (2.8%, n=7) closely followed by those who usually played in water (2.4%, n=6) and thirdly, by those who always put dirt in their mouth (2.0%, n=5).
At the end of the study, the researchers ecommended that health education should be given through community radios and televisions as a means of making the people understand the mode of transmission and methods of prevention of STH infection in order to eliminate STHs.

Published: December 2023

Background: Pubertal abnormalities can occur in HIV-infected boys and have negative effects on reproductive health, final adult height as well as psychosocial health and quality of life. This study was aimed at comparing the pubertal development in HIV-infected and non-HIV-infected boys attending two tertiary hospitals in Port Harcourt.
Materials and Methods: A Comparative cross sectional study was carried out involving 80 HIV-infected boys aged 10-18 years and 80 non-HIV-infected boy who were matched for age, sex and socioeconomic class.
Results: The mean age of the HIV-infected boys was 13.22±2.31 while that of the non-HIV-infected boys was 13.24±2.30 and this difference was not statistically significant. On physical evaluation using the Tanner staging method, only 64 (80%) HIV-infected boys had attained puberty as against 76 (95%) in the non-HIV-infected group (ꭓ2= 13.091, p-value=0.011). Pubertal onset occurred at a significantly later age in HIV-infected boys when compared to the non-HIV-infected ones (11.76±1.33 years vs 10.81±0.77 years). Pubertal delay was seen in 2 (2.5%) and this was significantly more common among those who were underweight as well as those in WHO clinical stages 3 and 4.
Conclusion: Pubertal onset occurred at a significantly later age in HIV-infected boys when compared to the non-HIV-infected boys. There is need to monitor pubertal development in HIV-infected boys so that deviations from normal can be promptly identified and necessary interventions given.

Published: December 2023

Bananas (Musa acuminata L.) are confronted with a number of challenges imposed by bacterial diseases which lead to huge yield losses. In order to improve the yields of the banana plantation, one of the recommended management strategies which would be inexpensive and environmentally friendly was developed. The objective of this study was to improve the sanitary state of banana plant. To achieve this objective, bacteria associated with the different banana organs were isolated on Nutrient Agar (culture medium) and their morphological identification was carried out based on the cultural characteristics and the colour of the bacterial walls observed under an optical microscope and using reference documents (bacteriological identification keys). Antibacterial activity of Lantana camara and Euphorbia hirta extracts were evaluated in vitro on agar medium aginst Xanthomonas campestris pv. Pseudomonas solanacearum and Ralstonia solanacearum. The results showed that the banana plant harbours a diversity of bacteria species, the most frequent being Ralstonia solanacearum as it was isolated from all infected organs. The yields of the equeous extacts of Euphorbia hirta and Lantana camara were particularly high (7% and 13%) respectively, compared to those of the ethanolic extracts which were lower. Aqueous extracts of Euphorbia hirta, at 50 mg/ml, had bactericidal activity against Ralstonia solanacearum and Pseudomonas celebensis. Aqueous extracts of Lantana camara, at concentrations of 25 mg/ml and 50 mg/ml, exhibited bactericidal activity against P. celebensis. Meanwhile, the ethanolic extracts of L. camara, at 50 mg/ml had bacteriostatic activity against the development of P. celebensis. Ethanolic extracts of E. hirta had bactericidal activity on the growth of Xanthomonas campestris at 25 mg/ml and 50 mg/ml. The same activity was obtained with P. celebensis at 50 mg/ml. These results suggest that the aqueous and ethanol extracts of the tested plants at high concentrations could be used as alternatives to chemical products in the fight against banana diseases especially Xanthomonas, Pseudomonas and Ralstonia. Hence further studies need to be undertaken in order to isolate the active compounds from these extracts with bactericidal potential.
Industrial Ecology
Authors: Hagan James 
Published: December 2023

AbstractThe components of industrial ecology are (1) the use of renewable, sustainable inputs, (2) optimal material and energy utilization with the elimination of waste, and (3) the use of recovered materials and discarded energy from society or other industries being used back in the supply chain and manufacturing process (industrial symbiosis). If industrial ecology encompasses all activities from the extraction of natural resources to the development and issuance of a final product, industrial symbiosis is the third part of that equation, using wastes or by‐products as inputs to the manufacturing process thereby reducing the need for extraction from natural sources. The circular economy is the interface between general society (ie, consumers) and their use of manufactured goods, and an industry that will need to utilize the materials of discarded products in manufacturing of new products.
Feasibility of eolian sound for urban wind speed estimation

Published: December 2023

AbstractWind‐speed measurement is crucial in designing wind‐resistant buildings and controlling the wind environment in urban areas. However, the current methods of measuring wind speed, such as anemometers and Doppler lidar, are associated with high costs. This study investigated an alternative approach to measuring wind speed using the eolian sound emitted from cylindrical objects in urban settings, such as electrical cables. The proposed method relies on a relationship between the frequency of Karman vortex generation, which gives rise to eolian sound, and wind speed, considering the diameter of a cylindrical object. This study addressed 2 research questions: (1) the possibility of capturing and identifying the eolian sound emitted from a cylindrical object using a generic recording device and whether the peak frequency of the recorded sound aligns with the theoretically predicted frequency; (2) the feasibility of estimating the direction of the eolian sound source to identify the object responsible for the sound emission. The authors conducted a series of experiments involving artificially generated eolian sound in an outdoor environment and analyzed the recorded sound signals. The analysis results were encouraging, confirming positive responses to both research questions. These results indicate the potential for a novel method capable of estimating wind speed.

Published: December 2023

AbstractAqueous zinc ion batteries (AZIBs) show great prospects in large‐scale energy storage applications, whereas this technology suffers from the lack of cathode materials with high capacity and stability. Here, a cathode material of SbO2 nanoparticles decorated onto the surface of K0.43V6O13 nanobelt is presented. The SbO2 is disclosed as proton‐phile and zinc‐phobic, which thus favors H+ intercalation. In consequence, the increase of H+ intercalation can offset the lattice shrinkage caused by Zn2+ intercalation, and contribute to excellent cyclic stability of the battery. Finally, SbO2/K0.43V6O13 delivers a reversible capacity of 414.2 mAh g−1 at 1 A g−1 after 1000 cycles with a retention of 103%, and 223.5 mAh g−1 at 20 A g−1 after 20 000 cycles with a retention of 89.3%, showing long cycling life at both low current and high current densities. This study provides new insights into the effecting factors for the performance of AZIBs cathode and an effective strategy to improve its stability.

Published: December 2023

AbstractEpsilon‐and‐mu‐near‐zero (EMNZ) metamaterials have garnered significant attention in near‐zero‐parameter metamaterial research for their exceptional ability to attain concurrent near‐zero permittivity and permeability. Nowadays achieving EMNZ properties through the use of metacomposites remains a novel endeavor. Presented here is an innovative approach of near‐zero‐parameter metacomposites, illustrating excellent and tunable EMNZ properties in the radio frequency regime. The self‐organization approach is applied to construct the conductive 3D network and the circuits, serving as the underlying framework for achieving EMNZ properties. Near‐zero permeability is effectively maintained while permittivity reaches epsilon‐near‐zero frequency regime. Efficient manipulation of electromagnetic parameters is initially realized via adjusting component content in metacomposites. Significantly, an excellent EMNZ property is observed as carbon content reaches 15 wt.% at 915 MHz. Through both numerical simulations and experimental testing, the PGC metacomposites have exhibited tunneling effects and directional emission characteristics, confirming their EMNZ properties. Besides, the Lego‐like adjustment facilitates the achievement of EMNZ property and advances the EMNZ frequency point to 700 MHz, expanding the EMNZ range. Furthermore, thanks to the remarkable excitation effect of photo‐induced adjustment, the metacomposite with low‐carbon content also achieves extraordinary EMNZ properties. This research offers promising self‐organized EMNZ metacomposites and lays the foundation for future endeavors in precisely adjusting near‐zero parameters.
