Relevance. The 28-spotted potato ladybird beetle, Henosepilachna vigintioctomaculata, causes severe damage to plants of the Solanaceae family in the south of the Russian Far East. Today the application of chemicals is the main method for protecting crops against the potato ladybird beetle. This leads not only to the eradication of the pest, but also to the pollution of agricultural ecosystems and the emergence of potato ladybird beetle populations that are resistant to pesticides. A study on the seasonal cycles of the development of the potato ladybird beetle may help to devise new methods for controlling this pest.Methods. We conducted laboratory experiments to study the developmental timing ofa potato ladybird beetlepopulation. The number of eggs was counted, and then the eggs were placed in Petri dishes. The number of emerged larvae was recorded on a daily basis. The hatched larvae were transferred to glass containers (hereafter rearing cages) in batches of 10. We recorded the dates of the transition from one immature developmental stage to another notingthe simultaneity of these transitions. At the onset of the pupal stage, the date was recorded and food was withdrawn from the rearing cages. Scientific observations were carried out on the emergence ofyoung beetles. Field research on the phenology of the potato ladybird beetle was conducted at afield site of 40 m2. The timing of the following events was recorded: the emergence of the adult beetles from diapause, the colonization of the potato field, the beginning and the end of oviposition, the emergence of the larvae and the pupae, the flight of the new insect generation.Results and conclusion. Our laboratory experiment on the immature developmental stages of the potato ladybird beetle revealed that the egg stage was 4-5 days in duration, the larval stage was 16-17 days and the pupal stage was 4-5 daysunder optimal conditions. We also observed deviations from the mean values, which could be conditioned by external factors. For instance, the duration of embryonic development depended either on humidity or on the time range of hatching from one egg mass. The observed deviations of the developmental timing of the larvae and the pupae were most probably due to the quantity and quality of the available food, and the presence of secondary metabolites and glycoalkaloids in it. The field research on thephenology of the potato ladybird beetle showed that there was only one generation in 2020, but two generations in 2021. After comparing climatic conditions in 2020 and 2021, we concluded that Henosepilachna vigintioctomaculata can produce two generations during dry and hot years.

Objectives. To determine whether an association exists between Social Vulnerability Index (SVI) scores and 40-year recertification violation within the City of Miami, Florida. Methods. A cross-sectional, observational secondary data analysis of social and housing vulnerability, including the Centers for Disease Control and Prevention’s SVI overall themes, estimated median year a housing unit was built, and 40-year recertification code violation data. We conducted the study using data sets from 2013 to 2018 at the census tract level in response to the collapse of Champlain Tower South in Surfside, Florida. Results. Every 1-unit increase in a census tract’s SVI score yielded a 21-fold increase in the odds of being a census tract with high 40-year recertification violations. Census tracts within the third quartile for SVI scores had approximately 9 times the odds, and tracts within the fourth quartile had 11 times the odds of being tracts with high 40-year recertification violations. Conclusions. Findings demonstrate that inequitable conditions exist among the City of Miami’s most socially vulnerable residents, through greater exposure to risky housing environments.

Authors: Kunze Kyle N. , Eliasberg Claire D. , Strickland Sabrina M. , Lane Joseph M. 
Published: June 2022

Case:
We present the case of a 42-year-old man with a coracoid base fracture that progressed to nonunion. The patient underwent percutaneous autologous bone-marrow and demineralized bone matrix (DBM) grafting 8 months after injury, with all intraoperative cultures positive for Cutibacterium acnes. The patient had no prior surgeries, but he began shaving his axillae around the time of injury. He was treated with amoxicillin; by the 6-week follow-up, computed tomography demonstrated complete fracture healing.

Conclusion:
Our case demonstrates a novel etiology of coracoid nonunion treated successfully by eradicating the infection with biologic augmentation by percutaneous autologous bone-marrow grafting with DBM and oral antibiotics.

Authors: Jong Stephanie T , Stevenson Rebecca , Winpenny Eleanor M , Corder Kirsten , Sluijs Esther MF van 
Published: June 2022

Abstract
Background: High quality longitudinal studies investigating changes in health behaviours over the transition into early adulthood are critical. However, recruiting and retaining adolescents is challenging. This study explored adolescents’ perspectives of sign up and continued involvement in research. Methods: Forty-eight individuals (15-20y) participated in nine focus groups. Thematic analysis resulted in seven themes. Results: Driving factors for sign-up included social connection e.g., joining with peer groups, personalised feedback, and incentives, primarily financial. Key barriers were lack of interest, the perception of commitment, and timing of recruitment. Young people preferred recruitment processes via social media with messages tailored to their motivations, monthly data collection of maximally 20-30min and hybrid data collection with some in-person contact with a consistent, non-judgemental researcher. The provision of autonomy and choice, and financial incentives, were perceived to promote retention. Conclusions: Adolescent recruitment and retention strategies need to align with contemporary interests and motivations. Studies should involve adolescents to develop a planned, systematic approach to participant sign-up and follow-up. Effective and ineffective recruitment and retention strategies should be reported as part of study findings. Future research should trial how perceived barriers to study engagement can be overcome.

Published: June 2022

Abstract
Biped robot has attracted increasing attention because of its flexible movement and strong adaptability to the surroundings. However, the small output torque and the weak impact resistance of motor drive, as well as the large energy consumption of hydraulic drive limit the performance of biped robot drive system. Aiming at these shortcomings, an electric-hydraulic hybrid drive system of biped robot was proposed in this paper. The robot platform was designed based on the prototype of Zhejiang Lab biped robot. The mathematical model of hydraulic drive system and the simulation model of mechanical structure were established to analyze the dynamic characteristic and the load force during walking. The value function reflecting the energy consumption of the hydraulic drive system was proposed. The pressure of the accumulator in the hydraulic power unit was selected as the control parameter. In order to get the minimum value of the value function, so as to reduce the energy consumption of the hydraulic driving system, the control parameters were optimized by genetic algorithm. From the simulation results, the proposed optimization algorithm can improve the efficiency by 3.49%.

Published: June 2022

Abstract
Let R be a commutative ring with identity and let Ω(R)* be the set of all nontrivial principal ideals of R. The reduced cozero-divisor graph Γr(R) of R is an undirected simple graph with Ω(R)* as the vertex set and two distinct vertices (x) and (y) in Ω(R)* are adjacent if and only if (x) ⊈ (y) and (y) ⊈ (x). In this paper, we characterize all classes of commutative Artinian non-local rings for which the reduced cozero-divisor graph has genus at most one.Mathematics Subject Classification (2000) 05C10 · 05C25 · 05C75

Published: June 2022

Abstract
Background
A growing body of evidence indicates that the outbreak of COVID-19 has had a significant influence on individuals’ cognition, emotion, and psychological health. This study aims to explore the effect of the association between time perspectives and self-control on the well-being and ill-being among college students in China during the COVID-19 pandemic.
Methods
We conducted an online survey involving 1,924 participants in mainland China during the outbreak of COVID-19. A series of self-rating questionnaires measuring the perceived impact of COVID-19, time perspectives, self-control, as well as the statuses of well-being and ill-being were administered. Multiple indirect effects of time perspectives and self-control on well-being and ill-being were analysed through structural equation modelling.
Results
The present-hedonistic time perspective (an orientation on immediate impulses of pleasure) meditated the effects of perceived impacts on both well-being and ill-being, and the future time perspective (considering the outcomes of actions and decisions) mediated the effects on well-being. Moreover, the mediating effects were further mediated by self-control. Specifically, the impact of the future time perspective on ill-being was fully mediated by self-control (β = 0.01, p < 0.01).
Conclusion
Based on the results, it is evident that the present-hedonistic time perspective, the future time perspective, and self-control are related to higher levels of well-being and lower levels of ill-being, thereby providing further insight into the theoretical framework of time perspectives during the COVID-19 pandemic. Additionally, our findings provide practical implications for psychological interventions during the on-going COVID-19 pandemic, focusing on the effects of time perspectives and self-control on the well-being and ill-being of different individuals.

Abstract
Background: Acupuncture combined with auricular acupressure has been used as a complementary and alternative treatment for smoking cessation in Hong Kong for over 10 years. This study aimed to verify its therapeutic effects and safety for smoking cessation and to evaluate its effects on tobacco dependence, smoking behavior, anxiety levels and sleep disturbances between successful and unsuccessful quit smokers in Hong Kong.Methods: This prospective, multicenter clinical study conducted between September 2020 and February 2022 in Hong Kong was part of the Guangdong-Hong Kong-Macau Greater Bay Area project on smoking cessation. Thirty eligible current smokers (mean age: 47.10 years; 40% female) were recruited and received standardized acupuncture plus auricular acupressure treatment twice weekly for 8 weeks. The primary outcome was the success rate of smoking cessation at week 24. The secondary outcomes were the success rate of smoking cessation at weeks 8 and 16, exhaled carbon monoxide (CO) level, changes in scores on the Fagerström Test for Nicotine Dependence (FTND), Autonomy Over Smoking Scale (AUTOS), Hamilton Anxiety Rating Scale (HAM-A), Self-rating Anxiety Scale (SAS), and Pittsburgh Sleep Quality Index (PSQI). Adverse events were also recorded during the study period.Results: Of 30, 28 participants completed 6 or more treatment sessions and all completed follow-up assessments. At week 24, the success rate of smoking cessation was 46.67%. The successful quit rates at weeks 8 and 16 were 36.67% and 43.33%, respectively. The overall change in mean FTND scores from baseline improved significantly from weeks 2 to 24 (P < 0.05), with the successful quit group showing significantly greater improvement between weeks 8 and 24 (P < 0.01). Compared with baseline, there were significant reductions in the mean AUTOS scores from weeks 6 to 24 (P < 0.001), with the successful quit group showing greater improvement at weeks 16 (P = 0.04) and 24 (P < 0.001). No significant changes were detected in exhaled CO levels and HAM-A, SAS, and PSQI scores. No study-related adverse events were observed.Conclusions: Acupuncture combined with auricular acupressure is an effective alternative treatment for smoking cessation and reducing tobacco dependence and cigarette consumption among Hong Kong smokers.Trial registration: Chinese Clinical Trial Registry, No. ChiCTR2000033650.

Effect of Contamination of Bulk-Fill Flowable Resin Composite with Different Contaminants during Packing on its Surface Microhardness and Compressive Strength: In Vitro study.
Authors: Aidaros Nawal Hassan 
Published: June 2022

Abstract
Background: Proper isolation and restoration of class V subgingival cavities are technique sensitive, thus the resin composite restoration is liable to contamination. This in vitro study was conducted to evaluate the surface microhardness and compressive strength of bulk-fill flowable resin composite after being contaminated during its packing.Materials and methods: Resin composite discs were prepared using split mold. The contaminated specimens were allocated into four groups (n=20) according to the contaminant used: hemostatic agent (Group 1), alcohol (Group 2), artificial saliva (Group 3) and powdered gloves (Group 4). The non-contaminated specimens (n=20) were used as control group. The surface microhardness and compressive strength of each group were tested one-day post-photocuring (n=5) and one-month post-photocuring (n=5). Values were presented as mean, standard deviation (SD) values and confidence intervals. Results: At one-day and one-month post-photocuring, the highest surface microhardness mean values were recorded in control groups. The difference between all groups was statistically insignificant at one-day post-photocuring (p=0.299) and at one-month post-photocuring (p=0.880). The highest compressive strength mean values at one-day and one-month post-photocuring were recorded in control groups (110.42 MPa and 172.87 MPa respectively), followed by alcohol groups, then hemostatic agent groups, followed by artificial saliva with the least value recorded in powdered gloves groups (56.71 MPa and 49.5 MPa respectively). Conclusions: Contamination of bulk-fill flowable resin composite with hemostatic agent, alcohol, artificial saliva, or powdered gloves during its packing decreased its compressive strength at one-day and one-month post-photocuring; but did not affect its surface microhardness.Clinical Relevance:The findings confirmed that resin composite packing is a technique-sensitive procedure where any negligence contributing to resin composite contamination could lead to decrease of its mechanical properties.

Published: June 2022

Abstract
Objective: This study describes the development of an intervention to increase the frequency of audiologists’ asking about and providing information regarding mental wellbeing within adult audiology services.Design: The Behaviour Change Wheel (BCW), an eight-step systematic process, was followed to develop the intervention. Reports describing the first four steps are published elsewhere. This report describes the final four steps and details the intervention developed.Results: A multifaceted intervention was developed to change audiologists’ behaviours relating to providing mental wellbeing support to adults with hearing loss. Specifically, three behaviours were targeted: (1) asking clients about their mental wellbeing; (2) providing general information on the mental wellbeing impacts of hearing loss; and (3) providing personalised information on managing the mental wellbeing impacts of hearing loss. A variety of intervention functions and behaviour change techniques were incorporated into the intervention, including instruction and demonstration, information about others approval, adding objects to the environment, use of prompts/cues, and endorsement from credible sources. Conclusion: This study is the first to use the Behaviour Change Wheel to develop an intervention targeting mental wellbeing support behaviours in audiologists and confirms the usability and usefulness of the approach in a complex area of clinical care. The systematic development of the Ask, Inform, Manage, Encourage, Refer (AIMER) intervention will facilitate a thorough evaluation of its effectiveness in the next phase of this work.
