Published: June 2022

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 At the onset of the pupal stage, the date was recorded and food was withdrawn from the rearing cages.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.

Tableaux for some deontic logics with the explicit permission operator
Authors: Glavaničová Daniela , Jarmużek Tomasz , Klonowski Mateusz , Kulicki Piotr
Published: June 2022

In this paper we present a tableau system for deontic logics with the operator of explicit permission. By means of this system the decidability of the considered logics can be proved. We will sketch how these logics are semantically defined by means of relating semantics and how they provide a simple solution to the free choice permission problem. In short, these logics employ relating implication and a certain propositional constant. These two are in turn used to define deontic operators similarly as in Andersonian-Kangerian reduction, which uses different intensional implications and constants.

Postharvest Management Practices of Maize in Ethiopia: A Review
Authors: Yimer Arebu Hussen
Published: June 2022

Postharvest losses and their management practices of Maize production in Ethiopia were overviewed. Agriculture is vital for addressing food security problems in Ethiopia. Agriculture contributes to overcoming the food security problem through growth that distributes its benefits as widely as possible by increasing production and productivity. About 30 to 50 per cent postharvest loss is because of inappropriate collection, transport, storage and pest control systems in Ethiopia were found tremendous for different cereal grains. The review was done by collecting the various published and unpublished materials relevant information from different literature sources like libraries, research report, journals, books and Internet center. Postharvest quantity and quality loss of cereal grains in developing countries appear to be initiated mostly at the farm level, so the potential solutions for the problem are needed at the same level. To minimize losses and increase the shelf life of the food grains which inhibit the growth of pests and provide proper storage facilities, appropriate packaging materials and transportation facilities are required. A corrective suggestion on suitable approaches to loss reduction in postharvest handling of maize grains was reviewed. As the result of review, it concludes that further studies are needed concerning physical, bio-chemical and socio-economic aspects at each production level.
Artificial Neural Networks- An Introduction and Application in Animal Breeding and Production: A Review
Authors: Khanikar Dimpi , Phookan Arundhati , Gogoi Ankita
Published: June 2022

With the advent of newer methods and tools for accurate analysis, the outcomes of researches have become increasingly precise. This increase in reliability of research findings and forecasting is well demanded in various fields of science including those under animal breeding as well as its allied aspects such as production. One such recent breakthrough is an artificial neural network (ANN), which is a system of hardware and/or software programmed to function like the operation of neurons in the human brain. ANNs are a variety of deep learning technology, which also falls under the umbrella of artificial intelligence. The determination of milk yield, quality of meat animals, predicting breeding values, inferring demography and recombination, genome-enabled prediction are few of the sectors where ANN has proved to be a valuable asset. The correlation coefficient between the experimental values and those predicted with the help of ANN was found to be close to 1. These studies were a significant indication of the impactful ability of ANN. The early selection of superior bulls, culling of low performing ones, frequent prediction of breeding values and taking into account the non linearity encountered in biological research are few of the many benefits of using ANN in researches of animal genetics and production. Hence, considering its prodigious role, this current review has been written to highlight the role and impact of ANN in livestock studies.

Estimación de riesgo sísmico de las edificaciones del distrito de chancay mediante método Hazus
Authors:   , Carbajal Flores Luis Miguel , Ramón Dolores Johann Waldir
Published: June 2022

Con la posibilidad de un sismo de considerable intensidad, según el IGP y el CISMID, se hace necesario la presencia de investigaciones para prevenir y dar conocimiento de los riesgos que están expuestos la población. Es por ello, que la presente tesis propone una estimación del riesgo sísmico de las edificaciones del distrito de Chancay según metodologías visuales. El motivo de escoger a la ciudad de Chancay para este estudio es por su tipo de construcción que representa a la mayoría de las ciudades de la costa peruana. Estas construcciones realizadas principalmente por personas con conocimiento empírico “Maestros de Obra” y en la mayoría sin asesorías de un profesional de la construcción genera que estas edificaciones sean vulnerables. La vulnerabilidad asociada con el peligro sísmico representa un riesgo no solo estructural y de posibles pérdidas económicas, sino que en el peor de los casos pérdidas humanas. Por ello, es necesario informar a la población las posibles consecuencias que tendrían después de un evento sísmico de magnitud mayor a 8. Para el desarrollo de esta esta investigación se cuantifico el costo estructural de la ciudad tomando datos oficiales del gobierno y costos actuales de distintos proyectos que se desarrollaron en los índices 3.1 Material y 3.2 Recopilación, en el que se obtiene un valor aproximado de S/ 2.2 mil millones de soles. Para la evaluación se utilizó la metodología propuesta por el Fema en su manual de Hazus que se resumen en el Capítulo 2 Marco Teórico; así mismo, se debe indicar que esta metodología se realizó en Estados Unidos en el que propone 36 modelos estructurales en relación con el tipo de construcción con el que se puede obtener el porcentaje de daño de una estructura frente a un evento sísmico. Se debe considerar que los resultados son posibles aproximaciones ya que los coeficientes utilizados por la metodología presentan limitaciones que son mencionados según avance el desarrollo de la investigación. El motivo de utilizar metodologías visuales para determinar el riesgo es principalmente que la evaluación es una ciudad; el cual, cuenta con aproximadamente 15 mil estructuras que si es evaluada mediante métodos avanzados se tendría que acopiar información muy detallada que generan grandes costos, tiempo y por el gran número no sería del todo razonable. Finalmente se presentan los resultados y las conclusiones para un escenario sísmico de magnitud de 8.5 desarrollado en el Capítulo 5 Discusión de resultados para la ciudad de Chancay; en el cual se estima que la ciudad tiene un riesgo de 42.8% de daños que expresados en términos económicos es de S/. 954.3 millones de soles.

When Covid-19 began to enter Indonesia, the entire school process was immediately switched to an online method. Various efforts have been made by parents to deal with online schools, which unwittingly affect their mental condition, which so far has never accompanied children to learn from home. Therefore, the Indonesian government continues to strive to improve the quality of education during the pandemic. This study aimed to determine parents' perceptions of offline schools during the Covid-19 pandemic. The method used was descriptive with a questionnaire given to 67 mothers. The results were that most mothers (88.1%) felt that online learning reduced children's learning capacity. Most mothers (25.7%) complained that the absorption of material was less effective and maximal, 65.7% of mothers felt that offline learning should be implemented immediately because direct interaction with teachers was considered more comprehensive and effective, and 70.1% of mothers allowed their children to study offline during the pandemic with strict health protocols. Almost all respondents (97%) stated that offline schools can develop children potentially better than online schools. Most mothers (70.1%) felt that their children can maintain health protocols while at school if they are allowed to go to school offline.

Salât-ı Dâiyye ve Devâiyye
Authors: DEMİRTAŞ Yavuz
Published: June 2022

Arapçada hayır dua anlamına gelen pek çok kavramı ihtiva eden salâtı kısaca; “Hz. Muhammed’e (s.a.v.) merhamet, mağfiret, feyz ü bereket vs. hayırlar ihsan etmesini Allah’tan (c.c.) dilemek” şeklinde tanımlamak mümkündür. Dinî naslar (ayet ve hadisler) icabı her Müslümanın söylemesi gereken salât metinlerini mûsikî eşliğinde okumak, dinî Türk mûsikîsinde “salât” türünü meydana getirmektedir. Müslüman Anadolu insanının en fazla rağbet ettiği dinî Türk mûsikîsi türlerinden biri olan salât, ibadet mekanları olan câmilerde ve tasavvufî düşüncenin pratiğe dönüştüğü yerler olan tekkelerde büyük bir iştiyakla icra edilmiş, insan hayatının hemen her önemli safhasında teberrüken okunmuştur. Bu türe gösterilen büyük rağbet, pek çok salâtın ortaya çıkmasına vesile olmuş, bunlardan bir kısmı kayıt altına alınarak günümüze gelebilmiş, ancak bir kısmı da kayıt altına alınamadığından maalesef unutulmuştur. Bununla birlikte Anadolu'nun birçok yöresinde geleneksel olarak varlığını devam ettirmekle birlikte henüz kayıt altına alınamamış salâtlar da mevcuttur ki, bunlardan biri de Elazığ’da icra edilen uşşâk makamındaki “Salât-ı Dâiyye ve Devâiyye” adlı eserdir. Aynı zamanda çalışmamızın konusunu da oluşturan bu eser, bölgedeki tasavvuf çevreleri (özellikle de Kadirîler) tarafından okunmaktadır.

Published: June 2022

This present article aimed to analyze the educational equity among state schools located in vulnerable territories in the city of Guarulhos. The analysis involves the final year of elementary and high school. The database used was formed by data from the School Performance Assessment System of the State of São Paulo (Saresp) and the São Paulo Social Vulnerability Index (IPVS). A quantitative approach was used, and the data set was examined using descriptive and variance analysis, with social vulnerability in the territories and the color/race of students as independent variables and the average of the Basic Education Development Index of the State of São Paulo (Idesp), performance level in Portuguese, Mathematics and school flow as dependent variables. The results in the analyzed teaching stages demonstrate the existence of variations and distances between the learning of students enrolled in schools with different levels of social vulnerability, interfering with the advancement of educational equity, with prejudice to students from schools with greater vulnerability.

Published: June 2022

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. (Am J Public Health. 2022;112(8):1217–1220. https://doi.org/10.2105/AJPH.2022.306890 )

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.

Published: June 2022

Background: Loss of a fetus may cause mental health problems in women. The aim of the study was to determine the effect of Mindfulness-Based on Stress Reduction (MBSR) on anxiety, depression, and stress of women with early pregnancy termination. Methods: This study was performed on 106 women with the early loss of pregnancy; in Shiraz, Iran. The intervention group underwent eight counselling sessions. Pre-test and posttest were performed in both groups with DASS 21 questionnaire. Data were analyzed by SPSS 23.Results: There was a statistically significant difference between mean score of anxiety in the intervention group (7.9 ± 1.07) compared to the control group (13.79± 5.36), stress in the intervention group (9.26 ± 1.25) compared to the control group (7.66 ± 18.13) and depression in the intervention group (7.83 ± 1.05) compared to the control group (16.26± 11.06) (P <0.0001).Conclusions: MBSR can be suggested to promote women's mental health.
Recruitment and retention into longitudinal health research from an adolescent perspective: a qualitative study
Authors: Jong Stephanie T , Stevenson Rebecca , Winpenny Eleanor M , Corder Kirsten , Sluijs Esther MF van
Published: June 2022

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.

Pressure Optimization for Hydraulic-Electric Hybrid Biped Robot Power Unit Based on Genetic Algorithm
Authors: Zhao Pengyu , Xie Anhuan , Zhu Shiqiang , Kong Lingyu , Zhang Dan
Published: June 2022

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%.

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.

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

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.

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.

Dairy cattle production is a substantial industry in Türkiye’s livestock sector, with a significant economic impact. Because of its proximity to Türkiye’s major market zone, the Mediterranean and Aegean regions, the province of Isparta can develop its milk production capacity and make investments in dairy production. Therefore, the purpose of this study was to look into the economic structures of dairy farms of various sizes in Isparta, a major milk-producing region in Türkiye. For this aim, production costs and drivers of profitability for dairy farms were examined. The study included data from 159 dairy cattle farms operating in the production period 2020–2021 in the designated area. Dairy farms were separated into three groups based on size and analysed consequently. The findings revealed that total feed consumption was higher on small-scale farms, while milk production was lower. Feed costs were the highest portion of the cost among the cost items (72.86%), followed by permanent labour costs (7.12%). Furthermore, milk sales income (64.39%) was the largest contributor to the average income in terms of the gross product value. Aside from milk production, it was discovered that cattle value appreciation (24.12%) increased farm income. Consequently, as farm size increased, production costs per animal unit fell while net profit rose. Finally, feed is the most significant input that boosts milk production costs. Also, larger farms were found to be more profitable in the study area. Thus, it was concluded that policies that could have a favourable effect on an increase in the cattle population on the farm should be advanced in the study area.

Parkinson's disease (PD) is associated with changes in neural activity in the sensorimotor alpha and beta bands. Using magnetoencephalography (MEG), we investigated the role of spontaneous neuronal activity within the somatosensory cortex in a large cohort of early- to mid-stage PD patients (N = 78) and age- and sex matched healthy controls (N = 60) using source reconstructed resting-state MEG. We quantified features of the time series data in terms of oscillatory alpha power, beta power, and 1/f broadband characteristics using power spectral density, and also characterised transient beta burst events in the time-domain signals. We examined the relationship between these signal features and the patients’ disease state, symptom severity, age, sex, and cortical thickness.PD patients and healthy controls differed on PSD broadband characteristics, with PD patients showing a steeper 1/f exponential slope and higher 1/f offset. PD patients further showed a steeper age-related decrease in the burst rate. Out of all the signal features of the sensorimotor activity, only burst rate was associated with increased severity of bradykinesia. Our study shows that general non-oscillatory features (broadband PSD slope and offset) of the sensorimotor signals are related to disease state and oscillatory burst rate scales with symptom severity in PD.
