Published: October 2021

Abstract
The aim of our study is to expand the world-wide knowledge about pollutant transport in sediments of medium-sized meandering rivers and to explain barium distribution in Kupa River (Croatia), as it showed as an ideal “natural laboratory”. Sampling was performed twice at the same places with the time span of 15 years to see the changes in Ba concentrations after that period. Ba was analyzed using ICP-MS method on clay + silt sediment fraction (<63 µm). Modelling was performed in R environment (R version 3.5.1, 2018) and for solving the sediment transport equation of Ba in Kupa River a program based on finite differences is constructed. After barite mine ceased operation in 1990, Ba is still entering Kupica and Kupa rivers, as karstic underground still contains large amounts of barite waste. Ba concentrations in Kupa River sediments are still increasing consequently along the whole river length, except in Kupica River and first downstream sample in Kupa River. It seems that in this part of river course erosion exceeded deposition processes. Also, there is an indication of changing the way of underground Ba transport. Erosion and deposition processes lead to formation of peak of Ba concentrations in the lower course of the Kupa River. Most important conclusion is that the mentioned peak was formed under one or two flood episodes, when sediment eroded from the upstream locations and was brought and deposited in the lower course of the river. Our modelling predicts that Ba source will not cease completely during the next 20 years.

Abstract
Background: Substance use-related disorders have become a major psychiatric issue globally. The energetic youth who contribute meaningfully to national development are the most affected population by this social menace. This study aimed to examine the knowledge and perception of the youth on substance use-related disorders and the perceived effects on their lives.Methods: The study used a qualitative approach to explore the perceptions of substance use-related disorders in the Kwabre-East Municipality of the Ashanti Region of Ghana. The purposive technique was used to select 35 participants based on a set of inclusion and exclusion criteria. The data were gathered through focus group discussions and interviews in the Twi language and audio-recorded. Data were transcribed from Twi to English in a written form. The data were categorized into themes based on similarities and differences. Thematic analysis was used to analyze the data. The emerged themes have been presented as main findings, which are supported by quotations from the participants. Results: The study identified that substances commonly abused by the youth were alcohol, tramadol, gasoline product, glue, and marijuana. Again, it was found that peer influence, poor parental control, and loss of a job (poverty), perceived academic enhancement, and imitation of role models were factors that caused substance abuse among the youth. In addition, the following were identified in terms of the effects: mental illness, cardiovascular conditions, family exclusion, insecurity, and stigmatization.Conclusion: The initiation and implementation of drug preventive interventions by relevant stakeholders are crucial in preventing the commencement of any undesirable behaviour among the youth as far as substance abuse is concerned.

Published: October 2021

Abstract
Atrial fibrillation (AF) is a common cardiac arrhythmia that affects millions of people. a substantial genetic contribution to AF has been identified by number of studies over the years. The SNP that is often linked with genetic predisposition to AF is rs2200733 located in the intergenic region close to PITX2 gene which is implicated in cardiac structure and function. rs2200733 is commonly observed in major global populations. Our study aimed to establish the prevalence of this important SNP among young healthy adults in order to assess the risk of genetic susceptibility which could culminate into AF later in life. The study identified a substantial frequency of rs2200733 in Indian population at 21%.

Abstract
Context. Biodiversity patterns depend on landscape structure, but the spatial scale at which such dependence is strongest (scale of effect, SoE) remains poorly understood, especially for elusive species such as arboreal mammals.Objectives. We assessed the SoE in arboreal mammals and evaluated whether it depends on which biological responses and landscape variables are measured. We expected the number of species to be more reliant on spatial patterns of larger landscapes than relative abundance, especially when considering larger bodied species, and connectivity-related landscape variables. Methods. We sampled arboreal mammals during one year using camera traps placed in 100 trees within 20 forest patches in the Lacandona rainforest, Mexico. We measured forest cover, matrix openness, patch density, and edge density within 13 concentric buffers to identify the SoE of each landscape variable on the number of species, total abundance, and species-specific abundance.Results. Unexpectedly, edge density tended to have larger SoE than forest cover and matrix openness, and the SoE did not differ between number of species and total abundance. Yet, the SoE tended to be positively related to body mass.Conclusions. Mammal responses to edge density seem to be regulated by large-scale processes, such as an increasing dispersal in landscapes with higher edge density, and not by local-scale processes (e.g. edge effects). Species richness and total abundance seem to be moderated by ecological processes acting across similar spatial scales, but the SoE tends to increase with body mass. Therefore, conservation plans for larger mammals should be implemented across larger spatial extents.

Abstract
As mobile devices flourish, users can conveniently use the network services through the mobility of mobile devices. The most popular environment is the Mobile Ad Hoc Networks (MANETs), which consists of wireless hosts that communicate with each other in the absence of a fixed infrastructure. Data transmission for MANET is mainly achieved through peer-to-peer communication and forwarding technology without restrictions on the direction or extent of movement. This type of flexible architecture is suitable for emergency relief and military applications. As a result, a set of network nodes, called connected dominating set (CDS), is thus proposed as the virtual backbone of MANET. It mainly forms a CDS through a group of gateway nodes, and through this CDS for message delivery and routing management to reduce overall power consumption. Therefore, in the past, many scholars have proposed improved CDS construction algorithms to achieve a minimum number of CDS. In this paper, the Improved Relative Complement Sufferage CDS (IRCS-CDS) algorithm is proposed to effectively find out the stable and minimum CDS. Besides, the IRCS-CDS can adapt to the changeability of MANET even in a more loosely distributed network environment. The complexity of the proposed IRCS -CDS algorithm is O(2n2+3n), which is lower than other algorithms. Therefore, the proposed IRCS-CDS algorithm is more stable and efficient even in a network environments with loose nodes or small node coverage radius.

Abstract
Background: The purpose of this study was to determine the differences in the clinical effectiveness of supraclavicular nerve protection, if any, between percutaneous external locking plate fixation and open reduction with internal fixation (ORIF) in the treatment of clavicle fracture.Methods: A total of 27 patients who suffered clavicle fracture and underwent treatment of percutaneous external locking plate fixation or ORIF in our department, from January 2015 to January 2020, were retrospectively collected. There were 19 males and 8 females with a mean age of 42 years (range 21 to 57 years). Supraclavicular nerves were protected in all patients during the operation procedures. Among them, 17 patients were treated by percutaneous external locking plate fixation, while the other 10 patients were treated by ORIF. The paresthesia in the affected shoulder and the superior lateral thoracic area after surgery was collected and analyzed. Additionally, the satisfactory rate after the fixation removal was used to evaluate the clinical effectiveness.Results: All 27 patients were successfully followed with a mean duration of 1.3 years (1 to 5.8 years), and all fractures achieved bone union finally. There were significant differences in paresthesia in the affected shoulder area and the superior lateral thoracic area between the two groups after surgery (P<0.05). The satisfactory rate in the percutaneous external locking plate fixation group was higher than that in the ORIF group after the fixation removal (P<0.05).Conclusions: Clavicle fracture treated by percutaneous external locking plate fixation has benefits in the protection of supraclavicular nerve, reducing the incidence of postoperative paresthesia in the affected shoulder and superior lateral thoracic area.
As a Warning to Others or Do the Same?——A Study on the Spillover Effect of Punishment against Interlocking Company
Authors: Meng Xiangge 
Published: October 2021

Abstract
Based on the theory of organizational penalty spillover, this paper discusses whether the punishment against interlocking company will affect the accounting information quality of the observing company through the channel of interlocking directors. The research results show that the observing company significantly improves the accounting information comparability within two years after interlocking company is punished when compared horizontally with an interlocking company that is not punished. The observing company also significantly improve the accounting information comparability within two years after the interlocking company is punished when compared longitudinally with before an interlocking company is punished. The findings show that the punishment against listed companies by CSRC and other regulatory authorities have spillover effect, the punishment is not only an act of correcting deviations after the event, but also an attempt to improve the accounting information quality of unpunished companies by punishment that is a Warning to Others.

Authors: Salimi Ahmad , Aylar Elham Mojarad , Shabani Mohammad 
Published: October 2021

Abstract
Purpose: Previous studies have demonstrated that phosphine gas (PH3) released from aluminum phosphide (AlP) can inhibit cytochrome oxidase in cardiac mitochondria and induce generation of free radicals, oxidative stress alteration in antioxidant defense system and cardiotoxicity. Available evidence suggests that cannabinoids have protective effects in the reduction of oxidative stress, mitochondrial and cardiovascular damages. The objective of this study was to evaluate the effects of trans-Δ-9-tetrahydrocannabinol (THC) on AlP-induced toxicity in isolated cardiomyocytes and mitochondria.Methods: Rat heart isolated cardiomyocytes and mitochondria were cotreated with different concentrations of THC (10, 50 and 100 µM) and IC50 of AlP, then cytotoxicity and mitochondrial toxicity parameters were assayed.Results: Treatment with AlP alone increased the cytotoxicity, depletion of cellular glutathione (GSH), mitochondrial reactive oxygen species (ROS) generation, lipid oxidation, mitochondria membrane potential (ΔΨm) collapse and mitochondrial swelling, when compared to control group. However, incubation with THC (10, 50 and 100 µM) attenuated the AlP-induced changes in all these parameters in a THC concentration-dependent manner. Interestingly, the obtained results showed remarkably significant protective effects of THC by attenuation the different parameters of cytotoxicity, mitochondrial toxicity and oxidative stress induced by ALP in isolated cardiomyocytes and mitochondria.Conclusion: It is the first report showing the protective effects of THC against AlP-induced toxicity, and these effects are related to antioxidant potential and inhibition of mitochondria permeability transition (MPT) pore by THC. Based on these results, it was hypothesized that THC may be used as a potential therapeutic agent for the treatment of AlP-induced mitochondrial dysfunction and cardiotoxicity.

Abstract
Background

White adipose tissue is considered as an important endocrine organ and regulates metabolism. We assessed the relationship between Chinese visceral adiposity index (CVAI) and the bone microstructure in early rheumatoid arthritis (ERA) patients. The relationship may be existed between bone loss and visceral dysfunction of fat metabolism in female early rheumatoid arthritis patients.
Methods

104 female ERA and 100 age-, gender- and BMI-matched healthy controls were recruited for the comparison of CVAI. All ERA patients were prospectively followed for 1 year. HR-pQCT scan of the distal radius, tibia and second metacarpal head were performed at baseline and after one-year. ERA patients were divided into two sub-groups according to the median CVAI value.
Results

CVAI in the ERA group was significantly higher than the controls group (p=0.01). At baseline, the high CVAI group had a higher ESR level (p=0.004) while the cortical volumetric bone mineral density (vBMD) was lower (at both the distal radius and tibia, all p<0.05) compared to the low CVAI group. Linear regression analysis revealed that a higher baseline CVAI was an independent predictor of a lower cortical vBMD at month 12 (distal radius: B=-0.626, p=0.022, 95%CI: -1.914~-0.153; tibia: B=-0.394, p=0.003, 95%CI: -1.366~-0.290); and a greater reduction in trabecular vBMD (tibia: B=0.444, p=0.001, 95%CI: 0.018~0.063; distal radius: B=0.356, p=0.008, 95%CI: 0.403~0.063).
Conclusions

CVAI is an independent predictor of trabecular bone loss in female patients with ERA, and adipose tissue dysfunction may be involved in the pathogenesis of RA patients, especially in female ERA patients.

Hydrologic and soil properties of mature bioretention cells in Ontario, Canada
Authors: Spraakman S. , Drake J. A. P. 
Published: October 2021

Abstract
Bioretention systems, which mimic natural hydrology and reduce volume of stormwater runoff, are a preferred solution for meeting water balance objectives, but lack of knowledge about the long-term performance of these systems hinders their wider adoption. This study was a field survey of mature (&gt;3 years and up to 10 years post-construction) bioretention cells across Ontario, Canada. The survey involved visual inspections, determination of soil physical parameters and soil-water interaction parameters, infiltration capacity testing and synthetic drawdown testing. Results indicate that infiltration capacity remains above the recommended minimum of 25 mm/hr, likely due to high content soils and development of soil structure due to biological factors over time. The drawdown times for three sites ranged from 5 minutes to 6 hours, much less than the maximum allowed drawdown time of 24–48 hours. Ksat (saturated hydraulic conductivity) was only moderately negatively correlated with age, and where data existed on KSat at the beginning of operation, KSat improved for six out of nine sites. Soil-water interaction properties more closely resembled loam soils than sandy soils, which may be due to the development of a soil structure over time. We recommend conducting visual inspections regularly over infiltration capacity testing for quick determination of maintenance needs.

A fitnesz szektor gazdasági és társadalmi jelentősége folyamatosan növekszik. A fitnesztermek által nyújtott szolgáltatások skálája egyre bővül és ezzel együtt a fitneszklubok népszerűsége is gyorsan nő a lakosság körében. A fitnesz szolgáltatók által kínált edzések bárki számára igénybe vehetők, könnyen elérhetőek, számtalan típusú, méretű fitneszközpont áll a sportolni vágyók rendelkezésére, amelyet azért is szükséges kihangsúlyozni, mert a mindennapos testmozgás fontos színterei lehetnek ezek a sportlétesítmények. Azt, hogy mi alapján választanak a fitnesz fogyasztók edzőtermet, számos tényező befolyásolhatja, kiemelt szerepet játszanak ebből a szempontból a szektorban dolgozó fitnesz szakemberek. Kutatásunk több részből tevődik össze, amelyben olyan debreceni fitnesz termeket elemeztünk, ahol csoportos óra is elérhető. Megvizsgáltuk alap és mellékszolgáltatásait, interjúkat készítettünk a termek edzőivel és gazdasági elemzést is végeztünk. Ebben a tanulmányban feltérképeztük a termek földrajzi elhelyezkedését a városon belül. Vizsgálatuk a fitnesztermek adottságait, a honlapon található információkat, közösségi oldalon való megjelenésüket. Eredményeink tizenegy debreceni fitneszteremről kapott információink alapján levont következtetéseinket tükrözik. Ezek szerint a fitneszklubok száma folyamatosan változik, évről évre zárnak be és nyitnak meg vagy alakulnák át a fitneszközpontok, amelyek mérete és a kínált szolgáltatások száma alapján széles skálán mozognak. Minden fitnesz terem biztosít a diákok számára kedvezményeket, egyes termek célcsoportjai kimondottan az egyetemi hallgatók. A bankkártyás fizetés minden teremben elérhető szolgáltatás, a SZÉP kártyát a termek nagy része elfogadja fizetőeszköznek. Az elmúlt években a TRX, alakformáló és spinning óratípusok voltak a legnépszerűbbek. A közösségi oldalon népszerűbb termek folyamatosan, napi rendszerességgel osztanak meg híreket, ajánlásokat. Annak ellenére, hogy a vizsgált termek próbálják követni az éppen aktuális trendet, mégis vannak elmaradások, minőségi és mennyiségi különbségek a termek szolgáltatásai között.
