Authors: Rashidi Fatemeh , Mirghafourvand Mojgan , Malakouti Jamileh 
Published: November 2022

Abstract
Background: In addition to mothers, fathers may find the perinatal period difficult and complicated and experience a wide variety of emotions such as fear, anxiety, and depression. These emotional changes can adversely affect a father’s relationships with his infant and wife. Although most of the mental health problems experienced by fathers have generally been assessed in developed countries, there are insufficient data in developing countries. Hence, this study aimed to determine the fear of childbirth and its relationships with anxiety and depression among Iranian fathers.
Methods: In this cross-sectional study, the cluster sampling method was employed to enroll 302 husbands of pregnant women visiting health centers in Tabriz, Iran, in 2022. The data collection tools were the Sociodemographic and Obstetric Characteristics Questionnaire, Paternal Fear of Childbirth Scale, Spielberger’s State-Trait Anxiety Inventory (STAI), and Edinburgh Postnatal Depression Scale (EPDS). To assess the relationships of fear of childbirth with depression and anxiety, Pearson correlation tests was conducted in a bivariate analysis, and the general linear model (GLM) (with adjusting sociodemographic and obstetric characteristics) was employed in a multivariate analysis.
Results: The mean (±SD) of paternal fear of childbirth score was 48.39 (±14.10) within the possible 17–85 range. According to Pearson correlation test results, fear of childbirth had significant direct correlations with depression (P< 0.001; r= 0.47), state anxiety (P< 0.001; r= 0.60), and trait anxiety (P< 0.001; r= 0.51). The adjusted GLM results indicated that an increase in fear of childbirth score significantly increased depression (B= 0.18; 95% CI:0.13 to 0.22; P< 0.001), state anxiety (B= 0.45; 95% CI: 0.38 to 0.53; P< 0.001), and trait anxiety (B= 0.35; 95% CI: 0.27 to 0.42; P< 0.001) scores obtained from participants.
Conclusions: The research results indicated that paternal fear of childbirth significantly affected paternal anxiety and depression levels in the perinatal period. Therefore, it is recommended to develop comprehensive programs to screen fathers for fear of childbirth and psychological problems and to implement appropriate preventive and therapeutic interventions.

Published: November 2022

Abstract
Background
Hypertension in children and adolescents has become a major public health problem worldwide. However, due to the lack of epidemiological data and the absence of clear risk factors for hypertension, it is likely that many pediatric hypertensive patients are not correctly identified and given adequate attention. This study aimed to investigate hypertension prevalence and risk factors in adolescents in southwest China.
Methods
A junior high school-based cross-sectional study was conducted involving a total of 886 pupils (466 males and 420 females) aged 11 to 14 years in the first and second grades of two schools. Height, weight, waist circumference, skinfold thickness, and blood pressure (BP) were measured according to standard protocols, and blood samples were collected for uric acid (UA), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c). Multivariate logistic regression analysis was used to find the risk factors associated with hypertension, and multiple linear regression analysis was used to find the factors affecting systolic and diastolic BP.
Results
The overall prevalence of hypertension and elevated BP was 14.4% and 16.9%, respectively. Obesity (OR: 5.73, 95%CI: 3.27–10.03) and overweight (OR: 2.33, 95%CI: 1.54–3.52) were associated with hypertension. Hdl-c (standardized β = 0.098, p = 0.001) and TC (standardized β = 0.075, p = 0.023) were associated with systolic and diastolic BP, respectively.
Conclusions
The Chinese junior high school students who participated in the survey had a high prevalence of hypertension related to obesity and overweight. Notably, dyslipidemia may have influenced the development of hypertension.

Published: November 2022

Abstract
The article provides an analysis of the distribution of lichen species across 11 test sites laid on the territory of the Burabay National Park in 2018–2019. The total area of the Burabay National Park is 129.3 thousand hectares, where more than 700 vascular plants grow. It was formed in 2000 in the northern part of the Republic of Kazakhstan in order to preserve the unique natural complex and use it for recreational, scientific and cultural purposes. It is part of the Shchuchinsko-Borovskaya resort area. Geographically, it is an island-type ring structure, which is an oasis surrounded by expanses of steppes. On the territory of the Burabay National Park there are multiple large lakes: Borovoe, Shuchye, Maloe and Bolshoe Chebachye, Maybalyk, Katarkol. To identify the full species composition of lichens, all types of substrates were examined on the test areas: the surface of trunks and branches of trees of different species and conditions (live, dry, dead wood), rotting wood, soil, stones. 44 species of lichens belonging to 9 families and 19 genera have been identified in the vicinity of the National Park. The taxonomic composition of lichenobiota is as follows: Peltigeraceae (3 species), Teloschistaceae (3), Lecideaceae (3), Physciaceae (5), Parmeliaceae (14), Cladoniaceae (13). The families Dermatocarpaceae, Verrucariaceae, and Lecanoraceae include one species each. The largest number of species of the National Park Burabay are represented by epiphytes.

Abstract
Context
It is widely recognised that the Covid-19 pandemic has negatively impacted individuals’ mental health. However, little emphasis has been put on the possible influence of socio-economic factors in the relationship. In the context of the COVID-19 pandemic, our objectives were (i) to assess the relationship between education level and mental health in French adults, and (ii) to study the influence of the economic, social, health and the COVID-19-related factors in men and women respectively.
Method
Data are from 32,581 individuals representative of the French population who responded to the weekly survey “Baromètre COVID-19” between April 7th and May 31st 2020. Education level was self-reported (university degree, high school qualification, vocational certificate/qualification, no diploma). Anxiety-depressive state was derived from four items related to the frequency of occurrence of depressive and anxiety symptoms, and summarized in an overall validated anxiety-depressive score. Multivariate linear regression analyses were carried out with nested adjustments of variables related to economic, social, health and Covid-19 contexts to assess the relationship between education and anxiety-depressive state.
Results
In total, 45% of individuals reported symptoms of anxiety-depressive state (53% in women versus 36% in men). Among men, those with a vocational certificate/qualification and those with no diploma had a greater risk of having a higher anxiety-depressive state compared to those with a university degree (βVocational certificate/qualification=0.16 [0.04; 0.27]; βNo diploma=0.75 [0.43; 1.07]) while among women, the risk of anxiety-depressive state increased as education level decreased (βBaccalaureate=0.37 [0.25; 0.49]; βVocational certificate/qualification=0.41 [0.28; 0.54]; βNo diploma=0.8 [0.49; 1.12]).. For both men and women, economic, health, and Covid-19 factors partly attenuate these associations while social factors marginally modified the relationship. After accounting for confounders and intermediate variables, the absence of a diploma remained associated with anxiety-depressive state among men, while the whole educational gradient of anxiety-depressive state persisted among women.
Conclusion
In France, at the end of the first wave of COVID-19, individuals with a lower level of education had a higher risk of anxiety-depressive state. This association was more pronounced for women, highlighting a process of social inequality in health possibly related to gender. This should be considered in future prevention and public health interventions.

Published: November 2022

Abstract
The primary purpose of this investigation is contamination mapping in surrounding areas of Irankuh Pb–Zn mine, located in central Iran, using an integrated approach of principal component analysis (PCA) with the Concentration-Area (C-A) and Power Spectrum-Area (S-A) fractal models. PCA categorized the 45 elements into eight principal components. Component 2, containing the toxic elements of Pb, Zn, As, Mn, Cd, and Ba, was identified as contamination factor. This multivariate contamination factor was modeled using the C-A and S-A fractal methods (in spatial and frequency domains) to delineate pollution areas. Modeling of PCA data using the C-A fractal method showed four main populations for contamination factors. Two populations with higher fractal dimensions are associated with contamination from mining activities or anthropogenic effects. Low fractal dimensions are considered the background population which has not been affected or is less affected by these activities. Five geochemical populations were obtained for contamination factors using the S-A fractal modeling of PCA in the frequency domain. Therefore, various geochemical populations were achieved using geochemical filtering and two-dimensional inverse Fourier transformation. The geochemical populations related to classes 2, 3, and 4 containing intermediate frequency signals showed the pollution anomaly. The spatial distribution of pollutant geochemical signals exhibits excellent conformity with the mining operation limit and tailing dam location as pollutant sources. The results indicate that the elements of Pb, Zn, Cd, and As have significant values in the surrounding soils rather than their concentrations in the earth’s crust. The results demonstrate that the S-A fractal models can more precisely delineate the environmental anomaly than the C-A fractal model, especially in intermediate frequency populations.

Abstract

Optoelectronic tweezers (OETs) based on dielectrophoresis (DEP) force is a valuable tool for the manipulation of particles and cells. However, DEP-based methods that can measure the electrical parameters are always preformed on static metal electrode DEP systems. Here, we present a partitioned single-sided OET chip that combines an OET system and microfluidic channel. Unlike classical sandwich-structure OET chip, the single-sided chip is close to the metal electrode DEP system but can switch functions easily. Numerical simulations are studied to analyze the electric field on a microfluidic chip and pro-vide data for characterizing cell electric properties. The focusing and electro-rotation are successfully realized by partitioned multi-signal OET system. By analyzing the rotation speed, some specific electric param-eters of Raw cells are characterized. The work has laid a foundation for OET-based single-sided chip fabrication and experiment validation.

Abstract
In order to study the influence of different guide vane angle variation on performance characteristics of reactor coolant pump (RCP) during idling process, the external characteristics of RCP model with five different guide vane angles at idling process state were analyzed. Radial force characteristics and blade load characteristics of RCP were analyzed. The results show that the head and torque changes of pump with different guide vane angles in different idle period are consistent. The head of DY1model (Guide vane angle increases sharply first and then decreases gently, which convexity is large) is the highest and torque is small. The head drop rate of DY5 model (Guide vane decreases first and then increases, and the concavity is large) is the highest and torque is the largest. With the idling, the radial force of impeller and guide vane decreases gradually. The radial force of DY5 model impeller is small and the fluctuation range is weak. The radial force of DY4 model（Guide vane shows concavity change with gentle increase）impeller before idling is the largest. In the nonlinear transition of idle period, the total radial force of DY4 model is 235N when idling for 32s, which is nearly 30 times lower than that before idling, and the radial force decreases the most. In different idling periods, the radial force amplitude of guide vane of DY5 model is the largest, and the radial force decrease amplitude of guide vane of DY4 model is the largest in the whole idling period. The impeller blade load of DY4 and DY5 model pumps with concavity guide vane angle change law is significantly higher than that of other model pumps after the relative position of streamline is 0.6. When the relative position of the guide vane along the streamline direction is less than 0.5, the load fluctuation of the guide vane of each model pump is large. when the relative position is greater than 0.5, the blade load fluctuation is relatively small.

Abstract
Government subsidies are an important way to promote the cooperation between land and sea enterprises, but there is not much authoritative answer on how to quantitatively distribute government subsidies to increase the cooperation level and realize profit maximization of enterprises in land and sea. Based on the dynamic framework theory,differential game model based on government subsidies were constructed,the optimal equilibrium functions of land and land enterprises was obtained.The results show that:(1)Before government the cooperative effort of the land and sea enterprises and profit optimization of the land enterprises under cooperative game is maximization,but the profit optimization of the sea enterprises under cooperative game is minimization. (2)Government subsidies can effectively improve the cooperative effort and achieve profit and social optimization of the land and sea enterprises in The Nash non-cooperative game and the master-slave game,these cooperative effort is equal to the cooperation game and these profit optimization is greater than the cooperation game.(3) However, the optimal subsidy of sea enterprises under master-slave game and land and sea enterprises under cooperative game is zero, and the increasing government subsidy is not conducive to social benefit optimization.So, guiding land and sea enterprises to form cooperative game is the best choice to minimize the financial burden and maximize profit maximization.

Published: November 2022

Abstract
Introduction and Objectives:
Little is known about Prohibitin (Phb1)’s role during liver regeneration (LR). Previously, we found that the expression of Phb1 was down-regulated in rat liver mitochondria at 24 h after 70% partial hepatectomy (PHx) based on subcellular proteomic analysis. Here, we further explored the potential role of Phb1 during LR.
Materials and Methods
The changes in the expression of mRNA and protein levels, subcellular distribution and abundance of Phb1 in rat liver during LR were observed after 70% PHx. Mitochondrial alterations and the level of apoptosis were observed through electron microscopy and flow cytometry. RNA interference-mediated knockdown of Phb1 (PHBi) was carried out in BRL-3A cells.
Results
Comparing with sham-operation control groups, Phb1 mRNA and protein levels were down-regulated at 24 h, up-regulated at 72 h and 168 h in 70% PHx test groups. Phb1 was mainly located in mitochondria, where its abundance was reduced at 24 h, significantly increased at 72 h and almost recovered to normal at 168 h. Phb1 was also located in nucleus, where its abundance was increased continuously 72 h and 168 hours after 70% PHx.. The altered ultrastructure and reduced mass of mitochondria during LR were nearly recovered to normal at 168 h. PHBi in BRL-3A cells resulted in increased S-phase entry as well as the number of apoptotic cells, and disruption of mitochondrial membrane potential.
Conclusions
Phb1 may play a role both in maintaining mitochondrial stabilization and in regulating cell proliferation and apoptosis of rat liver cells during LR.

Abstract
Pond-based aquaculture has developed as the main aquaculture system and plays a pivotal role in providing food fish, nutrition, incomes, and livelihoods for various value-chain actors in Pakistan. However, this technology is mainly used in intensive monoculture and little knowledge is available on polyculture approaches in Pakistan. Therefore, this study was conducted to evaluate the growth and production of fish at the different species composition in polyculture. The experiment was conducted for 90 days at the department of Fisheries and Aquaculture UVAS, Lahore, Pakistan. There were three treatments each with three replications. In all treatments, the stocking density was similar at different species compositions. All the ponds were subjected to the same regime of feeding and fertilization. Fortnightly random sampling was done to adjust the feeding rate. In this study, the Pangasius hypothalamus, showed significant variations with a final weight of 385.34 g, in T1, and 318.50 g, in T3 compared to others. %weight gain and % SGR of pangasius were comparatively higher among other fishes in T1 and T3. FCR of pangas was recorded as 1.9, in T1, and 1.30, in T3, respectively which shows a better result as compared to the control and other groups. In addition, the polyculture of the pangas influenced the nitrate level which was increased in the high-density group as compared to low density and control. At the end of the trial, we observed the cortisol and glucose levels which showed non-significant variations among all treatments, which is a positive indicator that there was not any stress on pangasius in the polyculture system. Due to positive effects on growth parameters, it is concluded that the polyculture of pangas with only Indian and mixed (Indian and Chinese carp) could be tried to enhance the economic benefits in Pakistan.

Abstract
Atmospheric rivers (ARs) are long narrow band of high water vapor flux that closely related to heavy rainfall. Flooding from heavy rainfall is one of the major hazards in south and south west of Iran. In this paper, the connection between ARs and heavy rainfall is analyzed by a methodology based on the vertically integrated water vapor transport (IVT). Heavy rainfall days are identified from the Iran Meteorological Organization (IRIMO) from 1987 to 2019. Our results suggest that, all inclusive heavy rainfall events over the south and southwest of Iran are associated with the contributions by the ARs and they matches tend to peak in the cool season. Larger IVT value in the region related to more precipitation and play important role in determining the amount of it. The IVT value intense when the AR crossed over the region. According to the results, there were four major sources of ARs that effected on south and south west of Iran generally include Gulf of Aden, the Red Sea, Arabian Sea and Soudan. The Red Sea is the most important source of moisture those intense ARs on their path in this region.

Published: November 2022

Abstract
The modification of current cellular networks, operating in ultra-high frequency (UHF) bands, to support high data rates with optimum coverage is leading to severe bandwidth congestion. As millimeter waves holding large unoccupied bandwidth are among the solutions, an investigation into the wideband characteristics of millimeter wave propagation is paramount. Results from such an investigation can be used for planning and designing indoor 5G wireless communication networks. The main objective of the paper was therefore to simulate and analyze the propagation characteristics of millimeter wave propagation in an indoor complex environment considering the geometry and motion of objects. Intelligent Ray Tracing (IRT) model was employed to predict wideband parameters that affect the propagation of millimeter waves on the second floor of Building-412 of Haramaya University. Propagation considered in this research was mainly from the direct path, single and two-times reflections, and diffraction from moving objects, walls, and indoor objects. The simulation results demonstrated that human shadows near receiver locations significantly obstructed and affected signal strength. Furthermore, the movement of persons in the corridor of the building caused temporal variations of received power, path loss, and delay spread in NLOS. Results were compared with CI path loss model parameters are derived from measurement and indicated that CI path loss model fits the best in indoor environments when compared to other models. As a result, the CI path loss model is chosen to validate the path loss predicted in this paper. This implies that the geometry and motion of objects impact indoor propagation, and hence indoor geometry and motion of objects need to be considered in planning and designing indoor wireless networks.
