Characterization of Biofilm production in XDR Proteus mirabilis isolated from Baghdad city hospitals

Objective(s): P. mirabilis is considered as extensive drug resistant pathogen in many studies as it can resist complex antibiotic regimes, such pathogen can be threat to public health, especially when it has the ability to produce biofilm. Therefore, biofilm production was characterized among XDR P. mirabilis local isolates in this research. Material and Methods: 100 P. mirabilis isolated from wound infections from patients admitted to Baghdad hospitals. They were identified using biochemical test and Vitek2 system. The MIC test for antibiotic sensitivity was done by Vitek 2 automated system. Biofilm production was identified phenotypically by twitching motility test, scanning electron microscope, and microtiter plate assay. Results: It could be revealed that 8/100 isolates were MDR, 90/100 isolates were XDR and pan drug resistance level was shown in only two isolates. 80% of isolates had motile ability through twitching assay, and scan electron microscope study revealed that 76% of XDR isolates could produce different stages of biofilm on coverslip placed in MacConkey broth. Microtiter plate assay revealed 81% of XDR isolates were biofilm producers. Conclusion: it could be concluded that extensive drug resistant P. mirabilis can produce biofilm hence resist several important antibiotics; making treatment of infection among wounded patients is such a challenge in many hospitals in Baghdad.
Spectrum Efﬁcient GFDM Based on Faster Than Nyquist Signaling

Future mobile communication system will provide high data rates for a miscellany of new applications. Spectrum efficiency is a key performance indicator that must be considerably improved for the beyond 5G networks. In this paper, a new approach to increase the waveform spectrum efficiency is investigated. This novel schemes combines the faster-thanNyquist signaling with generalized frequency division multiplexing, resulting in a scheme that can hold the main benefits of this innovative waveform with the high spectral efficiency gain. The scheme proposed in this paper abandons the orthogonality principle for the time-frequency grid, reducing the spacing between the subcarriers. The reduced subcarrier spacing does not affect the minimum distance among the transmitted sequences, if the Mazo’s limit is respected and the data can be recovered by a non-linear receiver without bit error penalties. In this paper, maximum likelihood receiver will be used for a proof of conception, showing that the bit error performance is equivalent to the one achieved by orthogonal systems. The system will be integrated with a forward error control scheme, showing that the proposed scheme can be fully integrated with modern error control codes, while improving the spectrum efficiency by 20%.
Impact of Exchange Rate Volatility to Stocks’ Return in Indonesia: The Augmented Markov-Switching Egarch Approach

The stock price is one indicator that represents the economic performance in a country. Changes in stock prices, including various factors, as an example, is the exchange rate changes as the representation from the foreign exchange market. The fluctuating exchange rate price also influences the volatility of the stock price. Furthermore, volatility has different high and low regime stages that will cause a disparate impact on the outcome of the relationship changes. This study aims to examine the presence of asymmetric volatility and its effects on the volatility of LQ45 stock returns, as well as the changes in exchange rates of Rupiah against USD from 1997 to 2017. Using the Augmented Markov Switching EGARCH approach, the results of this study indicate an asymmetric behavior in the volatility of LQ45 stock returns. High volatility regimes are more dependent and more unstable than low volatility regimes, and low volatility regimes dominate the duration compared to the high volatility regime. The good and bad news give different impact on LQ45 stock return volatility and exchange rate changes. Moreover, the unstable economies will respond faster than the stable economies in terms of facing the exchange rate changes.
Altruism and Burnout: Long Hours in the Teaching Profession

This article explores why many public school teachers work substantially more hours than required by contract, given that the elasticity of their earnings with respect to their hours is close to zero. The author introduces a theoretical framework for public-sector employees in which high levels of effort can indicate either altruism (for intrinsically motivated employees) or low productivity (for low-ability employees). Because intrinsically motivated employees derive higher utility from working in the public sector, they are less likely to exit it. Over time, selection makes high levels of effort more strongly predictive of altruism than of low ability. Findings show that teachers with very low levels of experience exhibit little or no relationship between weekly hours and the probability of remaining in teaching. This correlation becomes more positive as teaching experience increases. Similarly, the level of work hours is positively related to self-reported burnout at low levels of experience, but the relationship is reversed for teachers who have been in the profession longer.
The effects of different types of written corrective feedback on students’ texting mistakes

The main purpose of this research was to investigate the effects of different types of written corrective feedback on students' texting mistakes in English lessons. In the study, a mixed model including quantitative and qualitative methods was engaged. Two-factor ANOVA was used for mixed measurements to test the significance of the difference between the error numbers of the three types of feedback except direct feedback. The qualitative data of the study were collected by examining the texts and the interviews about the effect of the four feedbacks were made with the students. Content analysis and descriptive analysis were performed. At the end of the study, in the quantitative findings obtained, the most effective type of feedback is the underlined feedback. As for the qualitative findings obtained from the students' opinions, the feedback type in which the error is coded and the information is given is the most effective type.

Correlation between clinical and histopathological findings of five puzzling cases of cutaneous tuberculosis

Background: Cutaneous tuberculosis refers to the clinical manifestation of extrapulmonary tuberculosis affecting the skin. Determining the type of cutaneous tuberculosis from a patient afflicted with is challenging because clinical and histopathological similarities exist between types. Moreover, confirming a diagnosis of cutaneous tuberculosis is difficult because of its similarity with other diseases. For instance, typical and atypical cutaneous tuberculosis may have similar manifestations, but each disease is managed by completely different approaches. Microbiological examination with polymerase chain reaction and bacterial culture are the gold standard methods used to confirm a diagnosis of cutaneous tuberculosis. However, results often demonstrate negative findings. Case Illustration: Five cases of cutaneous tuberculosis, which include two cases of tuberculosis verrucosa cutis, two cases of scrofuloderma, and one case of lupus vulgaris were presented in this article. Four of the five cases demonstrated significant improvement after initiation of an antituberculosis drug regimen. Discussion: Diagnosis of cutaneous tuberculosis in these cases was confirmed through clinical findings and histopathological and microbiological examination. Conclusion: A negative result following microbiological examination does not completely exclude the diagnosis of cutaneous tuberculosis. Investigating the pathognomonic findings of cutaneous tuberculosis through histopathological examination is important to differentiate among its types correctly. Therefore, correlations between clinical and histopathological results are essential to establish a diagnosis of cutaneous tuberculosis.
Loneliness experience during distance learning among college students with ADHD: the mediating role of perceived support and hope

ABSTRACT This study examined the predictive role of attention deficit disorders (ADHD) on the experience of loneliness among college students during the move to distance learning and social distancing policy during the COVID-19 pandemic. The study examined a serial multiple mediation of students’ experiences with distance learning, perceived social support, and hope. We hypothesised that students with ADHD would experience social distress in addition to struggling with distance learning. However, we expect that social support and hope may mediate their loneliness. The sample consisted of 648 students (Mean age 27.99, SD – 7.08), in a medium size college in the centre of Israel. Participants were divided into two groups: 529 typical students and 119 students with ADHD. Loneliness, negative experiences during the use of distance learning, perceptions of social support, and hope were examined. Students with ADHD reported higher levels of loneliness and more negative experiences with distance learning than their peers. Results demonstrated that ADHD and negative experiences with distance learning predicted higher levels of loneliness, while college support and peer support in addition to hopeful thinking mediated these relations. The discussion focuses on the theoretical and practical aspects of loneliness and support while emphasising the therapeutic implications of hope.

Religiosity Performance of BMT Leaders and Its Implications to Sukuk Preference

BMT has a strategic role in the marketing of State Sukuk since this institution is a party that has capital constraints for the development of its business activities.This study aimed to analyze the performance of BMT leaders' religiosity value and their implications for the preferences of State Sukuk. This study uses a quantitative descriptive approach with field survey methods. 22 BMT leaders become the research sample with the institutions scattered in regencies and cities in West Java. The measurement of the performance variable of religiosity and preference uses a Likert scale 5. The results show that the religiosity performance of BMT leaders in West Java is categorized as good. However, a good understanding of religious values does not instantly boost BMT leaders' preference for State Sukuk. Inadequate information on the operationalization mechanism of State Sukuk is one of the reasons for the low preference of BMT leaders for state Sukuk
Demographic changes and economic growth: impact and mechanisms

ABSTRACT Using panel data on 172 countries from 1960 to 2019, this paper empirically analyzes the impact of population aging on economic growth and explores the underlying mechanisms. We find that the aging of the population significantly reduces the economic growth rate: when the population over age 65 increases by 1 percentage point, the per capita economic growth rate decreases by 2.6 percentage points. We examine four channels through which population aging may affect economic growth and find that three channels play significant roles: capital accumulation, labor supply, and economic structure, while technological progress and human capital accumulation do not seem to be significant. We also find significant heterogeneity in the impact across countries at different income levels: the effects are statistically significant for middle-income and high-income countries, but not for low-income countries.
Experimental study of turbulent premixed combustion in V-shaped flames

Experimental study of turbulent premixed combustion in V-shaped flames Sina Kheirkhah Doctor of Philosophy Graduate Department of Aerospace Engineering University of Toronto 2016 Characteristics of turbulent premixed flames were investigated experimentally. The investigations were performed using Mie scattering, Particle Image Velocimetry, Rayleigh scattering, and broad-band luminosity imaging techniques. Methane-air flames associated with a relatively wide range of turbulence intensities, fuel-air equivalence ratios, and mean bulk flow velocities were investigated. For a relatively moderate value of turbulence intensity, a new concept is introduced and utilized to provide a detailed description associated with interaction of turbulent flow and flame front. The concept pertains to reactants velocity estimated at the vicinity of the flame front and is referred to as the edge velocity. Specifically, it is shown that fluctuations of the flame front position are induced by fluctuations of the edge velocity. For a relatively wide range of turbulence intensity, several characteristics of turbulent premixed flames, namely, front topology, brush thickness, surface density, and consumption speeds are investigated. For the first time, several flame front structures are identified and studied. It is shown that, due to formation of these front structures, the regime of turbulent premixed combustion transitions from the regime of counter-gradient diffusion to that of the gradient diffusion. In addition to these, a comprehensive study is performed to investigate influence of flame configuration on several flame front characteristics. It is obtained that, although changing the flame configuration influences several flame characteristics, the trends associated with the effects of governing parameters on the characteristics are nearly independent of the flame configuration.
Impact of Trade and Financial Globalization on Renewable Energy in EU Transition Economies: A Bootstrap Panel Granger Causality Test

The globalized world has experienced significant environmental degradation together with raising global production and population. In this context, the employment of renewable energy use has become crucial for a sustainable environment and development. In the research, the mutual causality among renewable energy, trade and financial globalization, real GDP per capita, and CO2 emissions in EU transition economies experiencing the integration with global economy was explored through bootstrap panel Granger causality test for the period of 1995–2015. The causality analysis revealed a unilateral causality from trade globalization to renewable energy in Estonia, Latvia, and Slovenia, and from renewable energy to trade globalization in Croatia and Lithuania. However, no significant causality between financial globalization and renewable energy was revealed. On the other side, a unilateral causality from CO2 emissions to renewable energy in Lithuania and Slovenia, and from renewable energy to CO2 emissions in Czechia, Hungary, and Latvia and a reciprocal causality between renewable energy to CO2 emissions in Romania and Slovakia and a unilateral causality from real GDP per capita to renewable energy in Czechia, Romania, and Slovenia was discovered in the causality analysis.

Productivity Analysis of Tree-Length Harvesting using Farm Tractor in a Nordmann Fir Stand in Turkey

Because of the low investment costs, the winch equipped farm tractors usage is the most common logging technique for the primer transportation of wood-based forest products in Turkey. During the logging operations, farm tractors are commonly used for cable winching at a steep terrain while they are used for skidding operation on relatively flat terrain conditions in forest stands. The aim of this study was to evaluate the working conditions and determine the productivity of uphill winching using a farm tractor during tree length harvesting operation in a Nordmann fir stand (Abies nordmanniana). The study was conducted in Western Black Sea Region of Turkey. The average diameter and length of the forest products which were hauled from stump-site to landing areas were 17 cm and 28 m, respectively. The winching distances were ranged from 10 m to 70 m. Time analysis and field measurements related to independent variables (including winching distance, tree diameter, length and volume) were conducted while the farm tractor was winching the harvested forest products. For the farm tractor, the productivity was estimated and the cycle time prediction model was developed using the multiple regression method. It was found that the average hourly and daily productivity were 5.80 m/hour and 46.42 m/day for 8 hours, respectively. The most time consuming work element was winching (49.2%), followed with delay time (20.1%).
A phylogeny of the genus Limia (Teleostei: Poeciliidae) suggests a single-lake radiation nested in a Caribbean-wide allopatric speciation scenario

Objective The Caribbean is an important global biodiversity hotspot. Adaptive radiations there lead to many speciation events within a limited period and hence are particularly prominent biodiversity generators. A prime example are freshwater fish of the genus Limia , endemic to the Greater Antilles. Within Hispaniola, nine species have been described from a single isolated site, Lake Miragoâne, pointing towards extraordinary sympatric speciation. This study examines the evolutionary history of the Limia species in Lake Miragoâne, relative to their congeners throughout the Caribbean. Results For 12 Limia species, we obtained almost complete sequences of the mitochondrial cytochrome b gene, a well-established marker for lower-level taxonomic relationships. We included sequences of six further Limia species from GenBank (total N = 18 species). Our phylogenies are in concordance with other published phylogenies of Limia . There is strong support that the species found in Lake Miragoâne in Haiti are monophyletic, confirming a recent local radiation. Within Lake Miragoâne, speciation is likely extremely recent, leading to incomplete lineage sorting in the mtDNA. Future studies using multiple unlinked genetic markers are needed to disentangle the relationships within the Lake Miragoâne clade.

Morphometric and meristic characters of Otolithoides pama (Hamilton, 1822) occurring in Hooghly-Matlah estuarine system of West Bengal, India

The present study analysed the morphometric and meristic characters of Otolithoides pama (Hamilton, 1822) collected from the Hooghly-Matlah estuarine system of West Bengal, India. A total of 618 specimens (298 males and 320 female) were collected during the period of 18 months from November 2016 to April 2018 with length ranging from 100-384 mm and weight 7.29-470.71 g, respectively. The analysis of 14 morphometric characters revealed that standard length has the fastest growth rate when compared to total length, while eye diameter has the lowest growth rate when compared with head length. A high degree of significant positive correlation with the ‘r’ values ranging from 0.978 to 0.997 was observed among different morphometric characters of O. pama. Among nine of the meristic counts, the coefficient of variation was found to be highest in anal fin rays (6.31%) and minimum in dorsal fin rays (1.12%). Based on the meristic counts, the fin formula of O. pama from the present study can be described as B. 7 , D. 9-10/1/44-45, P. i/16-17, V. 1/5 , A. 2/7-8, C. 19-21, L. 48-52. The number of gill rakers on the first left gill arch ranged from 19-21.
The Explicit Attitude of Adolescents Towards Peers with Cancer

The social stigma of cancer is a powerful source of stereotyping and prejudice against people affected by oncology disorders. The research problem is presented in the following question: what is the formal and content characteristic of the stereotype of adolescents with cancer shaped by healthy peers. The cross-sectional included 2,370 high school students in Poland. The frequency analysis of open-ended descriptions and exploratory factor analysis of attributes representing basic domains of human functioning revealed that adolescent cancer patients were characterized in three domains: emotional, social, and physical appearance. Furthermore, cancer was linked with negative explicit prejudice. The obtained results and their practical implications are discussed in light of theories of stigmatization, stereotyping, and prejudice against people with cancer.
