Published: August 2022

Introduction. Indicators of aerosol suspensions, used to make an integrated rapid assessment of the ecological state of territories, allow quickly assessing the ecological status of residential areas of settlements without installing mobile or stationary ecological posts. Aerosol particles are the subject of this study. The purpose of the study is an integrated rapid assessment of the ecological state of the residential area of the Srednyaya Akhtuba settlement (the Volgograd region) located in close proximity to operating enterprises, engaged in the production of expanded clay. The following aerosol indicators are employed to achieve this goal: acidity (pH); specific electrical conductivity (EC, µS/cm); toxicity (development of tested objects (Lr, cm)); the number of particles and their mass fraction from the perspective of convolution of normalized basic factors. The research objectives include sampling of aerosol particles; preparation of aerosol suspensions; study of indicators of aerosol suspensions; identification of the ecological status of the territory of the residential area of the Srednyaya Akhtuba settlement.

Materials and methods. The studied material is the aerosol particles taken from the surface of the leaves of apricot trees (Prúnus armeníaca L.) in the residential area of Srednyaya Akhtuba, Sredneakhtubinskiy district, Volgograd region, October 2018. The sampling of aerosol particles and the preparation of aerosol suspensions were carried out using international methods. The study of the acidity index (pH) and specific electrical conductivity (EC, μS/cm) was carried out using the electrochemical equipment of the MULTEST series (Russia): an ion meter (IPL-101-1) and a conductometer (KSL-111), respectively. The study of the toxicity of aerosol suspensions was based on measuring the development of tested objects (Lr, cm); the study of the dispersed composition of aerosol particles, their quantity and mass fraction were carried out according to GOST R (All-Russian State Standard) 56929-2016.

Results. The studies allowed assigning the ecological status of “an environmental crisis” to the territory of the residential area in Srednyaya Akhtuba as of the spring and summer of 2018.

Conclusions. Sources of pollution must be identified and environmental actions must be developed to protect the residential area of the settlement from aerosol particles with a diameter of less than 10 microns (PM10).

Published: August 2022

Introduction. The authors present one of methods for measuring water flows through the intake of a hydroelectric power plant. The new structure has a metal frame and a folding rotary row. The authors analyzed the advantages of the proposed, and mase strength and hydraulic analyses. Computational studies of the stress-strain state, made with account taken of the actual hydrodynamic pressure, allow choosing the optimal position of measurement points, designing a frame structure, and making highly accurate measurements of energy characteristics.

Materials and methods. Top international publications, as well as archived materials, were analyzed to select the universal frame structure. The most promising directions were identified; the advantages and disadvantages of the proposed solutions were taken into account. Complex computational studies were performed using ANSYS Mechanical, a universal industrial software package, and ANSYS CFX, a specialized module for modeling flows of liquids and gases with account taken of turbulence.

Results. The position of measurement points that ensure the least distortion of the flow and tilt angles of hydraulic turntables were determined during the hydraulic simulation. The flow loads were taken into account when the stress-strain state of the universal frame structure was calculated; optimal design solutions were selected to ensure the strength and reliability of metal elements. Stress concentration zones were identified for monitoring purposes during installation.

Conclusions. Given the mathematical modeling data and experimental field studies, a universal frame structure for energy tests was substantiated. The new design ensures a measurement error of ±0.67 %, which corresponds to the leading world standards.

Improving Management of Opioid Use Disorder Training With Novel Resident Co-PCP Model
Authors: Azevedo Kristopher , Cantone Rebecca E. , Garvey Brian T.
Published: August 2022

Introduction: Multiple organizations have recommended primary care physicians (PCP) implement medication for opioid use disorder (MOUD) programs to address the opioid epidemic, but that has been hindered by residency graduates feeling unprepared to provide these services. This study describes a program innovation to increase exposure to MOUD in residents’ own continuity practices.
Methods: We designed, reviewed, and implemented a co-PCP model to increase resident MOUD visits at one rural health clinic in the Pacific Northwest that is part of a large academic health center. We then measured resident MOUD panels before and after to assess success of this novel program.
Results: After implementation of the novel co-PCP model, the number of residents having at least three MOUD patients increased from two (25%) to eight (100%) over 8 months.
Conclusions: The novel co-PCP model of care effectively increased exposure to MOUD care in one resident continuity practice. This may be a successful practice change for improving resident preparation to provide MOUD care after graduation and to expand access to these services for further progress on the opioid epidemic.

Karangantu fishing port symbolizes the rapid fishing industry in Serang, Banten. So many activities in the Karangantu fishing port area, such as a place for landing fisherman’s boats, shipping fish catches, and tourism object. These activities may impact the water quality. This research aims to analyze the water quality and pollution index in Karangantu fishing port. The water sample was carried out by purposive sampling in three stations around the Karangantu fishing port area: the estuary area, the fish auction, and the dock. Twelve parameters were analyzed: temperature, turbidity, transparency, TDS, TSS, pH, DO, COD, nitrate, cadmium, lead, and total coliforms. The water quality analysis result was compared by Class III water classification based on PP RI Nomor 82. Water quality was determined by the pollution index based on the minister of environment decree No. 115/2003. The result indicates that the estuary area is polluted, with a PIj score of 6.35; the fish auction and the dock f are in the moderately polluted categories, with PIj scores of 4.99 and 3.90. The worse pollution can be prevented by raising public awareness about the importance of clean water and providing waste management facilities.
Ancient environmental genomics: An Introduction
Authors: Nguyen Ngoc-Loi
Published: August 2022

Environmental DNA (eDNA) obtained from ancient samples such as
sediments, ice or water are valuable data sources for a wide range of
disciplines in past and present biodiversity and biogeography [1-4].
Within the field of ancient metagenomics, the number of published
genetic datasets has risen dramatically in recent years and have become
an increasingly powerful tool to investigate wide-ranging topics
[5]. However, the ancient environmental metagenomics remains many
issues that should be to be addressed relating to ancient DNA
(aDNA) such as degraded nature, incomplete reference databases,
sensitivity to contamination by modern DNA [6-8]. This review aims
to provide an overview of the use of ancient metagenomics in large-scale
ecological and evolutionary studies of individual taxa and communities
of both microbes and eukaryotes and illustrate the limitations, risks,
and potentiality of this ancient eDNA research via
high-throughput sequencing (HTS) technologies. Further, paleogenetic and
paleogenomics will provide diverse insights into studying evolution and
how the present world came to be.

In this letter, the angular jamming effect of electronically controlled
corner reflectors after a maneuver aircraft is analyzed. Motion
characteristics of the corner reflectors towed by a high-speed aircraft
are calculated through the Lagrange theory, and the angle measurement
error of the jamming method for the monopulse angle measurement
algorithm is analyzed based on the motion states and the electromagnetic
states (scattering or penetration) of the corner reflectors. Results
show that the measured angle by a monopulse radar seeker can be
effectively interfered by this method under complex maneuver motion

Modelling and analysis of temperature and rainfall variability impact on the coffee berry borer infestation with optimal control
Authors: Melese Abdisa Shiferaw
Published: August 2022

This study focuses on a nonlinear deterministic mathematical model for
the impact of temperature and rainfall variability on coffee berry borer
\emph{(Hypothenemus hampei)}. In the model analysis,
CBB free and coexistence equilibria are computed. The basic reproduction
numbers at a minimum and maximum temperature and rainfall are derived.
The qualitative analysis of the model revealed the scenario for
equilibria together with basic reproduction numbers. The local stability
of equilibria is established through the Jacobian matrix and the Routh
Hurwitz-criteria, while the global stability of equilibria is
demonstrated using an appropriate Lyapunov function. The normalized
sensitivity analysis has also been performed to observe the impact of
different parameters on basic reproduction numbers. The proposed model
is extended into an optimal control problem by incorporating two control
variables, namely, the preventive measure variable based on the
separation of susceptible coffee berries from contacting the pests based
on biological control and an increase in the death rate of colonising
females of CBB based on chemical control. Optimal disease control
analysis is examined using Pontryagin’s minimum principle. Finally, the
numerical simulations are performed based on analytical results and are
discussed quantitatively. Furthermore, the cost-effectiveness of control
strategies to determine the best approach to minimize the CBB burden was
studied. The finding of this study shows that the use of chemical
pesticides is very effective to combat pests with minimum costs.

We conducted a cross-sectional study using a questionnaire to explore
the late effects in survivors of juvenile myelomonocytic leukemia
(JMML). The attending pediatric hematologist oncologists completed the
questionnaires. All survivors (N=30) had undergone allogeneic
hematopoietic stem cell transplantation. Approximately 83% survivors
showed more than one late effect. The identified late effects included
endocrine, dental, skin, ophthalmologic, musculoskeletal, pulmonary,
neurocognitive, and cardiovascular dysfunction. The prevalence of short
stature and cardiovascular and kidney dysfunction was significantly
elevated among survivors aged ≥18 years. Therefore, a multidisciplinary
follow-up system for survivors of JMML is crucial.
A survey assesing the impact of COVID-19 and elexacaftor/tezacaftor/ifavacaftor on both physical and mental health in persons with cystic fibrosis
Authors: Sakon Colleen , Vogt Hilary , brown cynthia , Tillman Emma
Published: August 2022

While our survey showed that PwCF felt that the COVID-19 pandemic had
impacted their mental health more than ETI therapy, around 9% of survey
responders felt that ETI did cause an increase in either anxiety or
depression. This finding was similar to the numbers Spoletini and
colleagues found in their adult clinic. They also found that a dose
reduction of ETI improved or resolved mental health adverse events for
most patients. [2] A recently published study by Guimbellot and
colleagues studied ivacaftor levels in PwCF who were on ivacaftor
monotherapy and showed many patients had levels higher than the
published minimum effective concentrations.[6] Thus, there may be a
correlation between ETI levels and mental health adverse events that
should be further explored in a prospective manner.

Authors: Yi guangzhao , Kraker Marlieke E.A. de , Buetti Niccolò , Zhong Xiaoni , Li Jinyan , Yuan Zhe , Zhu Weimin , Zhou Jia , Zhou Hongyu
Published: August 2022

Background: Secondary bacterial pneumonia is an important complication
of seasonal influenza, but little data is available about impact on
death and risk factors. This study identified risk factors for all-cause
in-hospital mortality and secondary bacterial pneumonia among
hospitalized adult patients with community-acquired influenza. Methods:
A retrospective cohort study was performed at a tertiary teaching
hospital in southwest China. The study cohort included all adult
hospitalized patients with a laboratory-confirmed, community-acquired
influenza virus infection during three consecutive influenza seasons
from 2017 to 2020. Cause-specific Cox regression was used to analyze
risk factors for mortality and secondary bacterial pneumonia,
respectively, accounting for competing events (discharge alive and
discharge alive or death without secondary bacterial pneumonia,
respectively). Results: Among 174 patients enrolled in this study,
14.4% developed secondary bacterial pneumonia and 11.5% died during
hospitalization. For all-cause in-hospital mortality, time-varying
secondary bacterial pneumonia was a direct risk factor of death
(cause-specific hazard ratio [csHR] 3.38, 95% confidence interval
[CI] 1.25-9.17); underlying disease indirectly increased death risk
through decreasing the hazard of being discharged alive (csHR 0.55, 95%
CI 0.39-0.77). For secondary bacterial pneumonia, the final model only
confirmed direct risk factors: age ≥65 years (csHR 2.90, 95% CI
1.27-6.62), male gender (csHR 3.78, 95% CI 1.12-12.84) and mechanical
ventilation on admission (csHR 2.96, 95% CI 1.32-6.64). Conclusions:
Secondary bacterial pneumonia was a major risk factor for in-hospital
mortality among adult hospitalized patients with community-acquired
influenza. Prevention strategies for secondary bacterial pneumonia
should target elderly male patients and critically ill patients under
mechanical ventilation.
A simplified direct on-chip forward or reverse immune assay for understanding protein-protein interactions in the serum
Authors: liu qian , Ye lei , Li song , Gao yi , Li sheng , Liu biao , Li xiao , Du Wei-Dong
Published: August 2022

Background: The identification of protein-protein interactions is of
great challenge. Therefore, we conducted this study to fabricate a gold
surface biochip with activated sophorolipids in combination with
16-amino-1-hexadecanethiol hydrochloride. Methods: We designed a direct
on-chip immunological assay strategy for measuring ligand-receptor
interactions in a forward or reverse manner, that is, a ligand was
immobilized on the biochip surface and allowed to interact with its
specific free receptor in the liquid phase and vice versa. The
specificity of molecular interactions on the biochip was evaluated using
an immunological blocking assay and a chemiluminescent immunoassay. To
test the potential utilization of biochip, we used the serum of
hemophagocytic lymphohistiocytosis (HLH) patients as an experimental
entity. Results: The receptor CD25-based IL-2 and ligand IL-2-based CD25
assays revealed that the detection limits on the biochip were as low as
156pg/mL and 78pg/mL, respectively. Meanwhile, using the receptor- or
ligand-based platforms, we found that the positive rates of free IL-2
and soluble CD25 (sCD25) monomers in the sera of HLH patients were
14.3% and 71.4%, respectively, like our previous
specific-antibody-based biochip investigation. Also, the biochip shared
a good compatibility with CLIA assay in the measurement of sCD25(r=0.77,
P<0.01). Conclusions: The biochip platform can be expanded to
protein-specific serological diagnosis as a potential substitute for
immunoprecipitation and ELISA to understand the interactions between
proteins, ligands and receptors, and enzymes and substrates.

Published: August 2022

Background: Influenza is a persistent public health problem associated
with severe morbidity and mortality. Drug use is related to myriad
health complications, but the relationship between drug use and severe
influenza outcomes is not well understood. The study objective was to
evaluate the relationship between drug use and severe
influenza-associated outcomes. Methods: Data were collected by the
Influenza Hospitalization Surveillance Network (FluSurv-NET) from the
2016-2017 through 2018-2019 influenza seasons. Among persons
hospitalized with influenza, descriptive statistics and logistic
regression models were used to analyze differences in demographic
characteristics, risk and behavioral factors, and severe outcomes
(intensive care unit [ICU] admission, mechanical ventilation, or
death) between people who used drugs (PWUD), defined as having
documented drug use within the past year, and non-PWUD. Results: Among
48,430 eligible hospitalized influenza cases, 2,019 were PWUD and 46,411
were non-PWUD. PWUD were younger than non-PWUD and more likely to be
male, non-Hispanic Black or Hispanic/Latino, smoke tobacco, abuse
alcohol, and have chronic conditions including asthma, chronic liver
disease, chronic lung disease, or immunosuppressive conditions. PWUD had
greater odds of ICU admission and mechanical ventilation, but not death
compared with non-PWUD. Opioid use specifically was associated with
increased risk of ICU admission and mechanical ventilation. Conclusion:
PWUD had greater odds of ICU admission and mechanical ventilation than
non-PWUD hospitalized with influenza. These results support targeted
initiatives to prevent influenza and associated severe outcomes among
this population.
A massive hemothorax resulted from injury to the left subclavian artery branch during pacemaker implantation: case report and literature review
Authors: Cheng Xiaojun , Pan Guangmei , Guo Zhiyong , Zhang Yuping
Published: August 2022

Pacemaker implantation via subclavian venipection is a common
procedure.A patient who had a pacemaker implanted via subclavian
venipection developed a massive hemothorax 21 hours after surgery.The
video-assisted thoracic surgery(VATS) showed that the left subclavian
artery branch ruptured and bled,and titanium clip was used to clamp and
stop bleeding. For patients with difficulty in puncture process,even if
it is confirmed that the device is inserted into the subclavian vein,it
is important to be vigilant against damaging adjacent arteries in the
process, and strict electrocardiograph monitoring should be conducted
after surgery. Once hemothorax appears,VATS should be performed in
conjunction with the surgeon to locate the bleeding point and stop the
bleeding.
Nutrient supply shifts successional paths but not speed of grassland recovery from disturbance
Authors: DeSiervo Melissa , Sullivan Lauren L. , Kahan Larissa , Seabloom Eric , Shoemaker Lauren
Published: August 2022

Disturbance and environmental change may cause communities to converge
to a steady state, diverge towards multiple alternative states, or
remain in long-term transience. Yet, empirical tests of these
successional trajectories are rare, especially in systems experiencing
multiple concurrent anthropogenic drivers of change. We compared
competing models of succession in grassland communities subjected to
disturbance and nitrogen fertilization using data from a long-term
(22-year) experiment. Regardless of disturbance, after a decade
communities settled on equilibrium states largely determined by resource
availability, with species turnover declining as communities approached
dynamic equilibria. Species favored by the disturbance were those that
eventually came to dominate the highly fertilized plots. Furthermore,
disturbance made successional pathways more direct, revealing an
important interaction effect between nutrients and disturbance as
drivers of community change. Our results underscore the dynamical nature
of grassland succession, demonstrating how community properties such as
beta-diversity change through transient and equilibrium states.
Using Social Prescribing in Obstetrics and Gynaecology to Improve the Climate: A Review
Authors: Mimoglu Ecem , Alhakmi Fauzi
Published: August 2022

Climate change is a public health emergency, and its global impact on
women’s health has been well-described. As a key tool in this arena,
social prescribing enables climate-conscious, cost-effective, and
holistic solutions to many patient concerns by encouraging local,
environmentally friendly care that can effectively prevent carbon-heavy
outpatient appointments and surgical procedures. A variety of obstetric
and gynaecological issues can be tackled through this route, including
menorrhagia, labour choices, and vaginal pessaries. Existing evidence
suggests that there is great scope for the development of social
prescribing programs that can pave the way for collective action towards
greener, holistic patient care.

Authors: Kwong Lee Ting , Wong Sai Fun , So Po Lam
Published: August 2022

Objective: To evaluate subsequent menstrual, fertility and
psychological outcomes after uterine compression sutures.
Design: Prospective cohort study Setting: Tertiary
obstetric unit (6000 deliveries per year) Population: Women
with primary postpartum hemorrhage successfully treated with uterine
compression sutures (n=80). Methods: Women were followed-up in
postnatal clinic for two years after delivery. Subsequent pregnancies
were identified by territory-wide computer registry and telephone
interviews. Women with postpartum hemorrhage treated with uterotonic
agents only were chosen as controls. Main outcome measures:
Prevalence of menstrual abnormality, adverse pregnancy outcome and
psychological disturbance. Results: In our cohort, 87.9% of
women had return of menses within six months. Two Asherman’s syndrome
were diagnosed. Majority of women had similar menstrual patterns as
before. Among 23 subsequent pregnancies, no significant difference in
outcome was demonstrated. However, more omental or bowel adhesion
(37.5% vs 8.8%, p=0.007), recurrence of hemorrhage (68.8% vs 7.5%,
p<0.001) and repeat compression sutures (12.5% vs 0%,
p=0.024) were seen in women with previous compression sutures. Over half
of the couple declined future fertility with 38.2% of women recalled
unpleasant memory and 22.1% reported life-long adverse impact
especially tokophobia. Conclusion: Women with history of
uterine compression sutures had similar menstrual and pregnancy outcomes
compared to those who did not have sutures. However, they had higher
risk of visceral adhesion, recurrence of hemorrhage and repeat
compression sutures next pregnancy. Couple was more susceptible to
negative emotional impact. Keywords: Uterine compression

Parking-Specific Parameterization Method for FTire
Authors: Neumann Dominic , Friederichs Jan , Harris Mark , Weinberger Mario , Schramm Dieter , Bachmann Christian
Published: August 2022

Virtual steering system layout in the early development phase requires adequate tire models to predict realistic steering rack forces. An accurate representation of parking is particularly important, as the largest steering rack forces occur during this maneuver. Physical tire models are mainly parameterized for rolling conditions. Since the tire exhibits different mechanical behavior under nonrolling conditions, this article introduces a new parameterization procedure for the physical tire model FTire that characterizes the conditions during parking maneuvers. To this end, an additional full vehicle measurement setup is used to understand the tire motions, forces, and torques during parking. It is also shown that a tire model based on a standard parameterization procedure results in steering speed-dependent parking torque deviations of up to 17.5% when compared with component measurements. Thus, new measurement methods are developed to help parameterize the tire model for this maneuver. A linear friction tester is used to determine the friction interaction between tire and road at the relevant relative velocities. In addition, measurements are performed on a tire stiffness test rig, in which translatory and rotatory movements are overlaid. Furthermore, the contact patch shape, ground pressure distribution, and tire outer contour are digitalized and added into the model. A tire model based on the new parking optimized parameterization is then compared with the standard tire modeling approach and component measurements as well as the full vehicle measurements. In conclusion, improvements of up to 12% for drilling torque, up to 15% for longitudinal force, a more realistic lateral stiffness, a more realistic pressure distribution, and improvements of up to 8% when simulating the steering rack force can be stated. After the results are evaluated and interpreted, recommendations for future developments of this parameterization procedure and an extension of the virtual tire model are discussed.

Short stories are becoming very popular around the globe. Learning vocabulary, a crucial component of learning a foreign language, is at the heart of teaching a language and is important for language learners. The researchers believe that vocabulary plays a crucial part in learning any language. Therefore, it is crucial to look at the best strategies for enhancing vocabulary learning. With the aim of effectively utilizing short stories to improve vocabulary at the primary level, the current study was created to raise awareness among elementary-level teachers about how they might develop the English vocabulary of their students. The study was experimental with a pretest-posttest design. Sixty students were randomly selected from an elementary school in Bahawalpur, Pakistan. Twenty-five close-ended questions (MCQs) type questions for pre-test and post-test and the English reading assessment survey (ERAS) questionnaire were used to collect data, and the data were analyzed by using SPSS. The results show that most students spoke about three things: the value of short stories in vocabulary learning, their interest in reading short stories, and their approval of using short stories. The study implies that primary school English teachers should use short stories to increase their students' vocabulary.

Objectives: The study evaluated the bond strength, degree of conversion and fracture pattern of the hybrid layer in cement-dentin adhesion techniques.

Materials and Methods: Bovine teeth dentin blocks were divided according to the cementation techniques: G1- Conventional three-step adhesive and dual-curing resin cement; G2- One-step self-etch adhesive and dual-curing resin cement; G3-Self-adhesive resin cement; and G4- Self-adhesive primer and dual-curing resin cement. Specimens were submitted to thermal cycling, chemical aging or water storage. Bond strength was evaluated by testing machine; fracture pattern observed by optical microscopy, and degree of conversion evaluated in micro-Raman spectrophotometer. Data were analyzed by two-way ANOVA and Tukey's test (α=0.05). 

Results: G1 showed greatest bond strength (p<0.001) followed by the G2 with higher values compared to G3 and G4, and no difference between them. For G2, G3 and G4, the thermal cycling affected the bond strength. The greatest degree of conversion was for G2 with Single Bond Universal, significantly higher than Scotchbond and RelyX U200. G4 provided highest value for the cement layer, and statistically higher than G1. G1 showed the highest strength than G3 associated to resin cement or self-adhesive resin cement. Different fracture patterns were observed.

Conclusions: Aging methods reduced the bond strength. Degree of conversion was highest in the adhesive layer photo activated and in the cement layer with dual activation. Different fracture patterns were observed.

Clinical Relevance: Resin cements degree of conversion and fracture pattern of the hybrid layer are relevant factors in the different bond strength values obtained in adhesive protocols.

The study examined the effect of retirement planning on psycho-social adjustment during retirement among teacher retirees in the Tarkwa Municipality. The study was mainly a descriptive survey employing the qualitative approach to inquiry. Nineteen (19) retired teachers were selected using the purposive sampling technique. Data was collected using a semi-structured interview protocol and was analysed using content analysis. It was found that Ghana Education Service (GES) did not organise retirement seminars for the retirees prior to retirement, however, they were able to do some financial preparation for retirement though not inadequate. Also, those who did adequate planning were psychologically well adjusted. It was recommended that the GES through the Guidance and Counselling Unit, Financial Institutions, Non-Governmental Organisations (NGOs), and other stakeholders organise workshops and seminars to empower teachers for proper planning and adjustment towards retirement.

Aquaculture fastest growing business worldwide especially in developing countries. Fisheries are marine species and required an oceanic environment where fisheries could grow and live naturally. Off-shore aquaculture businesses need a real-time water quality monitoring system. So, aquafarmers could maintain the required environment for a sustainable and profitable business. This work represents an IoT-based realtime health management system designed for aquaculture and considered the most required health metrics for aquaculture. The proposed system used four primary sensors: water level, temperature, pH, and dissolved oxygen. Sensors connected with microcontroller Arduino Uno R3 and ESP 8266 wi-fi module are used for data transmission to the IoT source ThingSpeak. The designed system could access online through the web interface and phone App for aquafarmers. The sensor data was accurate, and the system worked as designed.
Determinants of Household Energy Utilization and Changing Behaviour in Kenya: Structural Equation Modelling Approach

Knowing the determinants of household utilization and changing behaviour is an important element in understanding the pathways towards clean, sustainable and modern household energy sources. This study, therefore, examines the drivers of household energy usage and choices in Western Kenya using structural equation modelling from 560 sampled households. The research was carried out in Western Kenya (Uasin Gishu and Bungoma counties) from a target household of 663,000. Data was collected using a structured questionnaire and were analyzed to find standard estimate (path coefficients), standard error, critical ratios and the level of significance using AMOS version 23. SEM analysis found that education level, income, residential status, peri urbanization, house size, house composition, age and gender of the household head were the determinants of household energy choices and changing behaviour among households both for cooking. On the other hand, SEM showed that household energy choices for lighting are significantly influenced by income level, family size, location, education level, and residential status. High income and more educated households residing in peri-urban were more likely to use cleaner cooking (LPG, electricity) while lesser households living in rural areas use firewood and agricultural residues for cooking. Rural households mostly adopt solar energy for domestic use because rural areas are isolated and detached from the power grid. Though income and education are the major factors, the research finds that numerous non-income factors similarly play a key role in determining household energy utilization and changing behaviour. This study offers the understanding of improving household energy planning and designing policy and interventions in Kenya and sub-Saharan African countries.
Greening the School Energy System: A Nigerian Case Study

The sustainable development goals (SDGs) of the United Nations incorporated inclusive and quality education for all as a key component. In this respect, technology-based education is best suited for achieving the purpose. Meanwhile, energy is central to the modern school system as it is used to power Information and Communication Technology (ICT) equipment needed as bedrock for technology-based education. Given the low energy access in Nigeria and the need for environmentally friendly energy systems, the adoption of clean energy options appears to be the preferred direction for schools in the urban and rural areas. Hence this study examines the concept of energy transition especially as it relates to the school system and uses a case study to demonstrate its application in the context of Nigeria. The study adopted the qualitative approach using observation schedule and interview guide in addition to secondary data obtained from school documents, vendor specifications and technical details of clean energy installation. The study found that two main factors influenced the adoption of clean energy for the school. The first was the need to access a cheaper and cleaner form of energy in the long run given the epileptic and rather expensive supply from the national grid and the carbon intensive alternatives that are readily available. Secondly, the school wanted to align with the environmental sustainability preferences of the founders of the school, who are very conversant with best practices in sustainable development and sustainable school management. Hence, the transition to clean energy was an aspect of an overarching green agenda which encompasses different environmental sustainability activities. The major challenge is the huge capital outlay needed to install and maintain the clean energy system. The greening program provided school age children who will eventually become the policy makers of tomorrow, the proper orientation they need for their future roles as stakeholders in the physical environment. In addition, the high cost of installation and maintenance of the system suggests that incentives are needed to encourage an increased uptake of clean energy systems not only in the school system but also across other building types.
