Evaluation the Relationship between Mental Workload and Fatigue in Shahroud Bank Employees
Authors: VASILOUEE Vahid , KARIMI Azim , TALEBI Seyedeh‌Solmaz
Published: August 2022

Introduction: Mental workload has been raised as one of the most important issues in the workplace. In jobs where there is a lot of workload, due to fatigue and improper scheduling, efficiency is reduced, causing decreased memory, impairs thinking, and decreased learning. Tired people are more likely to choose risky behaviors, such as taking shortcuts to perform their tasks. This study aims to determine the relationship between mental workload and fatigue in bank employees.
Methods: This cross-sectional descriptive-analytical study was carried out on 190 employees of Shahroud Bank in 2019. In order to collect data, the questioning method was done using NASA task load index (NASA TLX) for measuring mental workload and multidimensional fatigue inventory (MFI). Data analysis was performed by SPSS 22 at the significance level of 0.05 using Spearman statistical test.
Results: Bank employees had a degree of mental workload with mean score of 75.06, and two factors of mental stress and efficiency were relatively more important than other subscales. In terms of fatigue, bank employees had an overall degree of fatigue with mean score of 52.46, and two factors of general and mental fatigue were more important in their job.
Conclusion: The results of this study indicate that the overall mental workload is directly related to the activity reduction component. The decrease in activity also has the highest correlation with efficiency, mental, and time subscales, which reduces the activity and productivity of bank employees.

Authors: Mahmoodi Razieh , Pourmovahed Zahra , Zareei Mahmoodabadi Hassan , Mahmoudi Mohammad Reza
Published: August 2022

Background: Parents of premature infants are more likely to be exposed to stressful situations than parents of term infants. This study aimed to determine the effect of educational-supportive interventions on the tolerance of parents of premature infants admitted to the neonatal intensive care unit (NICU).
Methods: In this quasi-experimental study, the participants included 50 parents of premature infants admitted to one of the NICUs in Shiraz, Iran from October 2019 to May 2020. Parents were randomly assigned to intervention and control groups. Educational intervention (training package and its content) was done in five 45-minute sessions for two weeks and three times a week. The supportive care was provided one day after the intervention. The data were collected using a demographic questionnaire and Distress Tolerance Scale and analyzed by SPSS 24 using paired t-test, independent t-test, and chi-square test.
Results: The mean scores of the mothers' and fathers’ distress tolerance in the pre-intervention stage were 36.0 ± 6.1, 33.9 ± 7.4 in the control group (P < 0.14), and 38.4 ± 5.8, 38.0 ± 5.9 in the experimental group (P < 0.001), respectively. After the intervention, the mean scores of the mothers’ and fathers’ distress tolerance in the control group were 35.9 ± 5.3 and 36.5 ± 6.3, and in the experimental group 54.7 ± 5.3, 53.0 ± 6.0, which compared to before the intervention showed a significant increase (P < 0.001).
Conclusion: Supportive-educational programs can increase distress tolerance in parents of premature infants. In the future, these programs can be planned to promote the quality of infant care.

Since 2016, Nigerians have experienced a stable fuel supply even if prices have continued to rise. This supply stability came to a sudden halt in January 2022, bringing back memories of long queues and harsh living conditions witnessed since 2007. To explore the implications of this change we revisit our study on demanding power and accountability in the Nigerian energy sector. The study conducted from 2019–21 as part of the Action for Empowerment and Accountability (A4EA) research programme found a significant lack of accountability in fuel subsidy management in Nigeria.
Francisco Zarco en El Demócrata: la sátira como periodismo político
Authors:   Universidad Nacional Nacional México, Instituto de Investigaciones Bibliográficas, Mexico, Alcántara Edwin
Published: August 2022

Francisco Zarco es en 1850 un novel pero talentoso periodista del periódico El Demócrata que redacta junto con su amigo Antonio Pérez Gallardo. Ambos son empleados del Ministerio de Relaciones y Zarco tiene el cargo de oficial mayor, por lo que en ese momento su jefe es el notable abogado José María Lacunza, quien en 1849 suplió a Luis Gonzaga Cuevas en la difícil misión de hacerse cargo de los asuntos interiores y exteriores del país. Poco antes, en plena guerra con los Estados Unidos, el adolescente Francisco Zarco había dado muestras de su talento como escritor al ser nombrado redactor de las actas parlamentarias del Congreso de 1847 refugiado en Querétaro. Apenas hace dos años que las tropas estadounidenses dejaron la ciudad y Zarco ocupa el cargo de oficial mayor en el Ministerio de Relaciones, por lo cual, cuando El Demócrata salió a la luz pública en marzo de 1850, era natural que otros diarios de la época, como El Universal, calificaran al periódico recién nacido de ser un “papel ministerial”. Aunque por entonces todos los periódicos que venían al mundo se proclamaban independientes, no tenía nada de extraño que El Demócrata apareciera justo cuando se iniciaban las campañas de la prensa para postular a sus candidatos presidenciales en las elecciones de aquel año, con el fin de elegir al sucesor del viejo y tolerante presidente José Joaquín de Herrera.
Noche al raso, de la novela al cuento

A la caída del Segundo Imperio se condenó social y judicialmente a los simpatizantes del régimen en el poder. El caso de José María Roa Bárcena (1827-1908), crítico literario, traductor, poeta, novelista y periodista veracruzano, no fue la excepción. Antes de la Intervención francesa, Roa fue integrante del grupo de notables que apoyó la llegada de Maximiliano de Habsburgo y con él la instauración de una monarquía. Los primeros dos años de tal gestión participó a favor del sistema imperial y, desde la tribuna periodística, tuvo un papel muy activo. Del 13 de abril de 1865 al 31 de marzo de 1867 fue director y jefe de redacción de La Sociedad, uno de los diarios políticos y literarios de tendencia conservadora más influyentes desde 1857. El 10 de junio de 1870 salió a la luz el periódico independiente La Unión. Para la sección literaria de la publicación se anunció una novedad editorial. Desde el primer número saldría en el folletín el volumen titulado José María Roa Bárcena. Novelas originales y traducidas. De las novelas anunciadas, la única inédita era Noche al raso, pues las otras ya habían sido difundidas en la prensa nacional.

Este texto ofrece una interpretación respecto a una miscelánea de publicaciones que se logró recuperar en distintas bibliotecas y acervos históricos de la Ciudad de México, que, en el pasado, formaron parte de un proyecto cultural elaborado por las autoridades locales a través de la Oficina de Acción Educativa, de Reforma, Recreativa y Social del Departamento del Distrito Federal (DDF), a la que hoy podemos reconocer como el origen de la Secretaría de Cultura de la Ciudad de México. Editados y estampados entre 1929 y 1930, los más de 140 impresos revelan la intención de sus emisores: intervenir en la cotidianidad capitalina divulgando y reforzando la cultura posrevolucionaria, pretendiendo influir en los ciudadanos al establecer determinados estereotipos, símbolos, valores y conductas definidas.
Guillermo Vigil y Robles, explorador del relato fantástico
Authors:   El Colegio de México, Mexico, Viveros Anaya Luz América
Published: August 2022

A sus veintitres años, el joven estudiante de jurisprudencia Guillermo Vigil y Robles manda formar como libro, de lo más barato y bien hecho que pudo conseguir, un conjunto de relatos que había publicado en los periódicos en los que solía colaborar: La Familia, La Patria Ilustrada y El Liceo Mexicano; lo dedica y data de esta manera: “A mi querida madre. Agosto 15 de 1890”, e invita a su amigo Luis González Obregón ―antes de ser nombre de calle, cuando era un jovenzuelo erudito de veinticinco años― a que escriba el prólogo. A falta de mejor ocurrencia, Vigil lo titula simplemente con el nombre del género textual al que se adscribe la mayoría de los textos ahí reunidos: Cuentos. El libro se compone de doce relatos ―uno de los cuales es, más bien, novela corta―; en nueve de ellos se construyen atmósferas realistas en las que irrumpirá una infracción a las leyes naturales, que oscilan entre lo raro, lo insólito y lo inexplicable. En cuanto a los otros tres, en uno se recurre a la tradición narrativa del objeto que hace el relato de los dueños que ha tenido; en otro, se configura una atmósfera de miedo ante gritos misteriosos que son luego explicados racionalmente a modo de chasco, y en uno más no hay ningún elemento fantástico, maravilloso ni extraordinario, sino acaso el entorno de una fiesta de disfraces, por lo que discrepa del resto de relatos en cuanto a su construcción narrativa, pero es afín en el tipo de escenario urbano que describe y los personajes que configura, por lo que no sobra en el cuentario. Por lo tanto, no todos, pero sí la mayoría de los textos del libro puede considerarse bajo la poética de lo fantástico.

This paper considers the rotational motion of a satellite equipped with flexible viscoelastic rods in an elliptic orbit. The satellite is modeled as a symmetric rigid body with a pair of flexible viscoelastic rods rigidly attached to it along the axis of symmetry. A planar case is studied, i. e., it is assumed that the satellite’s center of mass moves in a Keplerian elliptic orbit lying in a stationary plane and the satellite’s axis of rotation is orthogonal to this plane. When the rods are not deformed, the satellite’s principal central moments of inertia are equal to each other. The linear bending theory for thin inextensible rods is used to describe the deformations. The functionals of elastic and dissipative forces are introduced according to this model. The asymptotic method of motions separation is used to derive the equations of rotational motion reflecting the influence of the fluctuations, caused by the deformations of the rods. The method of motion separation is based on the assumption that the period of the autonomous oscillations of a point belonging to the rod is much smaller than the characteristic time of these oscillations’ decay, which, in its turn, is much smaller than the characteristic time of the system’s motion as a whole. That is why only the oscillations induced by the external and inertial forces are taken into account when deriving the equations of the rotational motion. The perturbed equations are described by a third-order system of ordinary differential equations in the dimensionless variable equal to the ratio of the satellite’s absolute value of angular velocity to the mean motion of the satellite’s center of mass, the angle between the satellite’s axis of symmetry and a fixed axis and the mean anomaly. The right-hand sides of the equation depend on the mean anomaly implicitly through the true anomaly. A new slow angular variable is introduced in order to perform the averaging for the perturbed system near the 3:2 resonance, and the averaging is

Published: August 2022

The soil-borne pathogens, particularly Fusarium oxysporum f. sp. niveum (FON) and southern root-knot nematode (RKN, Meloidogyne incognita) are the major threat to watermelon production in the south-eastern United States. The role of soil micronutrients on induced resistance (IR) to plant diseases is well-documented in soil-based mediums. However, soil-based mediums limit the determination of the role(s) of individual micronutrients in IR. In this manuscript, we utilized hydroponics to assess the effect of controlled application of micronutrient, including iron (Fe), manganese (Mn), and zinc (Zn) on the expression of some IR genes (PR1, PR5, and NPR1 from salicylic acid (SA) pathway, and VSP, PDF, and LOX genes from jasmonic acid (JA) pathway) in watermelon seedlings upon inoculation with either FON or RKN or both. Plants were treated with higher (3X) or lower (0.5X) concentrations of micronutrients in Steiner solution (X= standard dose of micronutrient) for 7 days in a hydroponics system under greenhouse conditions. A subset of micronutrient-treated plants was inoculated (on the 8th day of micronutrient application) with FON and RKN (single and mixed). The expression of the IR genes in treated and control samples were evaluated using qRT-PCR. Although, significant phenotypic differences were not observed with respect to the severity of wilt symptoms or RKN galling with any of the micro-nutrient treatments within the 30 day-experimental-period, differences in the induction of IR genes were observed. However, the level of gene expression varied with sampling period, type and concentration of micro-nutrients ap-plied, and pathogen-inoculation. In the absence of pathogens, no significant changes were observed in the expression level of IR genes on 7th day of micronutrient treatment. However, pathogen inoculation affected the expression levels of the IR genes at 3-day post-inoculation. In FON inoculated plants, PDF was upregulated in high Fe treatment, whereas in RKN inoculated plants, low Mn treatment resulted in up-regulation of VSP. In the case of mixed inoculation with FON and RKN, the plants with low Zn treatment resulted in the upregulation of PR1. These observations suggest that the type and concentration of micronutrients in watermelon may potentially induce systemic resistance against FON and RKN through SA and JA pathways.

Authors: Leogrande Angelo , Costantiello Alberto , Laureti Lucio
Published: August 2022

In this article we analyze the determinants and the export trend of European countries of medium and high technology products. The data were analyzed using various econometric models, namely WLS, Pooled OLS, Dynamic Panel, Panel Data with Fixed Effects, Panel Data with Random Effects. The results show that exports of medium and high-tech products are positively associated, among other variables, with the value of “Average Annual GDP Growth”, “Total Entrepreneurial Activity” and “Sales Impacts”, and negatively associated with, among other variables, “Human Resources”, “Government and Procurement of Advanced Technology Products” and “Buyer Sophistication”. A cluster analysis was realized with the k-Means algorithm optimized with the Silhouette coefficient. The result showed the presence of only two clusters. Since this result was considered poorly representative of the industrial complexity of the European Union countries, a further analysis was carried out with the Elbow method. The result showed the presence of 6 clusters with the dominance of Germany and the economies connected to the German economy. In addition, a network analysis was carried out using the distance to Manhattan. Four complex network structures and two simplified network structures were detected. A comparison was then made between 10 machine learning algorithms for predicting the value of exports of medium and high-tech products. The result shows that the best performing algorithm is the SGD. An analysis with Augmented Data-AD was implemented with a comparison between 10 machine learning algorithms for prediction and the result shows that the Linear Regression algorithm is the best predictor. The prediction with the Augmented Data-AD allows to reduce the MAE by about 0.0022131 compared to the prediction with the Original Data-OD.

Background: The role played by the non-dominant parietal lobe in motor cognition, attention and spatial awareness networks has potentiated the use of awake surgery. When this is not feasible, asleep monitoring and mapping techniques should be used to achieve an onco-functional balance. Objective: This study aims to assess the feasibility of a dual-strip method to obtain direct cortical stimulation for continuous real-time cortical monitoring and subcortical mapping of motor and visual pathways simultaneously in parietal lobe tumour surgery. Methods: Single-centre prospective study between May’19-November’20 of patients with intrinsic non-dominant parietal-lobe tumours. Two subdural strips were used to simultaneously map and monitor motor and visual pathways. Results: Fifteen patients were included. With regards to motor function, a large proportion of patients had abnormal interhemispheric resting motor threshold ratio (iRMTr) (71.4%), abnormal Cortical Excitability Score (CES) (85.7%), close distance to the corticospinal tract – Lesion-To-Tract Distance (LTD) – 4.2mm, Cavity-To-Tract Distance (CTD) – 7mm and intraoperative subcortical distance - 6.4mm. Concerning visual function, the LTD and CTD for optic radiations (OR) were 0.5mm and 3.4mm, respectively; the mean intensity for positive subcortical stimulation of OR was 12mA±2.3mA and 5/6 patients with deterioration of VEPs>50% had persistent hemianopia and transgression of ORs. 12 patients remained stable, one patient had a de-novo transitory hemiparesis, and two showed improvements in motor symptoms. A higher iRMTr for lower limbs was related with a worse motor outcome (p=0.013) and a longer CTD to OR was directly related with a better visual outcome (p=0.041). At 2 weeks after hospital discharge, all patients were ambulatory at home and all proceeded to have oncological treatment. Conclusion: We propose motor and visual function boundaries for asleep surgery of intrinsic non-dominant parietal tumours. Pre-operative abnormal cortical excitability of the motor cortex, deterioration of the VEP recordings and CTD<2mm from the OR were related to poorer outcomes.

Published: August 2022

The accumulation of process waste in the production line causes fluctuations, bottlenecks, and increased inventory in workstations disrupting process flow. In this paper, the aim is the use a simulated value stream mapping (SVSM) as a lean assessment tool for decision-making in the continuous improvement process to influence and provide consideration and consistency on productivity improvement in the production system. The proposed methodology applied discrete event simulation for production process operations improvement to eliminate non-value adding times and provides good quality products at the lowest cost and highest efficiency. The results are the analysis of the current state of the production system in a South African truck manufacturing industry small and medium enterprise (SMEs) as a potential solution for the production system future state. The identified non-value adding times in the 6 most critical workstations was eliminated by SVSM which resulted in a productivity improvement of 4%, most importantly bringing the productivity to 95% and total cycle time improvement to 451 for small units and 466 for large units. The results proposed combined VSM and Simulation techniques which enhance the LEAN application by DES to increase productivity and performance improvement to remain competitive in the global economy.

A set of programs for the numerical simulation of the diffusion decomposition processes was developed by using simulation methods, kinetic and particle method. The complex has been validated on the model system Ni-Al by the growth of -phase separations. The results on the evolution of the distribution function and other characteristics of the ensemble, which in the zero volume fraction approximation are asymptotically in good agreement with the theory and the experiment, have been obtained. The peculiarity of the created program complex is the possibility of its adaptation to the description of the decomposition of multicomponent multiphase systems.

Chronic Positive Mass Balance is the Actual Etiology of Obesity: Time for A Paradigm Shift?
Authors: Manninen Anssi
Published: August 2022

According to known laws of physics, chronic positive mass balance is the actual etiology of obesity, not positive energy balance. The relevant physical law in terms of body mass regulation is the Law of Conservation of Mass, not the Law of Conservation of Energy. A recently proposed mass balance model (MBM) describes the temporal evolution of body weight and body composition under a wide variety of feeding experiments, and it seems to provide a highly accurate description of the very best human experimental feeding data. By shifting to a mass balance paradigm of obesity, a deeper understanding of this disease may follow in the near future.

Published: August 2022

Objectives. To quantify socioeconomic inequalities in COVID-19 mortality in Colombia and to assess the extent to which type of health insurance, comorbidity burden, area of residence, and ethnicity account for such inequalities.

Methods. We analyzed data from a retrospective cohort of COVID-19 cases. We estimated the relative and slope indices of inequality (RII and SII) using survival models for all participants and stratified them by age and gender. We calculated the percentage reduction in RII and SII after adjustment for potentially relevant factors.

Results. We identified significant inequalities for the whole cohort and by subgroups (age and gender). Inequalities were higher among younger adults and gradually decreased with age, going from RII of 5.65 (95% confidence interval [CI] = 3.25, 9.82) in participants younger than 25 years to RII of 1.49 (95% CI = 1.41, 1.58) in those aged 65 years and older. Type of health insurance was the most important factor, accounting for 20% and 59% of the relative and absolute inequalities, respectively.

Conclusions. Significant socioeconomic inequalities exist in COVID-19 mortality in Colombia. Health insurance appears to be the main contributor to those inequalities, posing challenges for the design of public health strategies.

Araştırma sonucunda ülkelerin sağlık ekipmanları ile sağlık göstergeleri sıralamalarının farklılıklar gösterdiği görülmüş, sağlık politikaları ve planlaması noktasında önerilere yer verilmiştir.
Construction and Performance Evaluation of Dual-Metabolite Oil-Producing Engineering Bacteria Suitable for Low-Permeability Reservoir
Authors: Yang Zhao , Zhihua Guo , JingChun Wu , Hanqing Shi
Published: August 2022

Microbial oil recovery (MEOR) technology has a wide application prospect in the field of enhanced oil recovery in low-permeability reservoirs, and genetic engineering plays an important role. At present, oil-production engineering bacteria constructed by genetic engineering are mainly used to obtain high metabolites and strong environmental adaptability; there are few reports on genetically engineered bacteria with different functional metabolites. However, the bacteria which could efficiently produce one metabolite have a poor ability to produce other metabolites. Therefore, in order to reduce the cost of nutrients and improve the effect of microbial oil recovery, dual-metabolite bacteria have been constructed for low-permeability reservoir. In this paper, four rhamnolipid expression plasmids are extracted from E. coli-produced biosurfactant. Then, the rhamnolipid expression plasmids are transferred into the bacteria-produced biopolymer by electrotransformation, and the metabolite performance of the constructed bacteria is evaluated. Finally, the profile control and displacement performance of the constructed bacteria are studied through low-permeability core experiments. The experimental results show that three bacteria, WS1, WS2, and WS3, are successfully constructed that have preferable ability, among which the bacteria WS2 has the best capacity for producing biopolymer and biosurfactant at the same time. After culturing 96 h, the viscosity of the bacteria WS2 fermentation broth could increase to 42.1 mPa·s, and the surface tension and interfacial tension of the fermentation broth could decrease to 24.3 mN/m and 0.035 mN/m, respectively. This time-varying biological viscosity ensures that the microbial system can enter the low-permeability reservoir at a low injection pressure, and the oil recovery of the low-permeability core could be increased by 10.18% after injecting 0.5 PV WS2 microbial system. The findings of this study can help for better understanding of gene construction and technical support for further popularization and application of MEOR in low-permeability reservoirs.

The dust pollution at fully mechanized heading face has seriously threatened the health of the miners. As the main technical means, the outer spray of roadheader has the problems of small coverage of fog field and low dust removal efficiency. Based on the multiscale swirl atomization model of LES-VOF, this paper simulated and analyzed the atomization process of the nozzle. The influence law of the diameter, the length and the circulation area ratio of the swirl chamber, and the swirl core angle on the swirl number and atomization effect were determined, and the nonlinear function relationship between variables was obtained. With the help of the BP neural network model, a new type of swirl nozzle is developed which is suitable for the outside spray system at fully mechanized heading face. The experimental results show that the error between the predicted results of the new swirl nozzle and BP network model is less than 15%, the atomization angle θc is 24.2°, the average particle size D32 is 64.43 µm, and the effective range Reff is about 2.1 m. At the same time, the total dust removal efficiency and respirable dust removal efficiency of the new swirl nozzle at the driver’s place are 61.10% and 63.85%, respectively, which are 21.69% and 20.92% higher than the original nozzle.

Along with the development of technology in recent years, artificial intelligence (machine learning) techniques that perform operations, such as learning, classification, association, optimization, and prediction, have started to be used on data on real estate according to the criteria affecting the value. Using artificial intelligence (machine learning) techniques, valuation processes are performed objectively and scientifically. In this study, machine learning techniques were employed to balance the real estate market, affected by the tourism sector in Alanya district of Antalya province, Turkey, and examine changes in value objectively and scientifically. First, the criteria affecting the real estate value were determined as structural and spatial, and data on real estate were obtained from the online real estate website. Then, the values of the real estate in the selected application area were predicted using machine learning algorithms (k-nearest neighbors, random forest, and support vector machines). Unlike studies in the literature, algorithm-based valuation using machine learning algorithms was performed instead of mathematical modeling. When analyzed for performance metrics, the best result was achieved with the support vector machines algorithm (0.73). Objective methods should be used to balance the exorbitant differences between real estate values, to regulate market conditions and to carry out a real estate valuation process free from speculative effects in coastal areas where tourism factor is effective. This study indicated the applicability of algorithm-based machine learning techniques in real estate valuation.

Aim
This research aims to study the role of environmental parameters in encouraging Iranian mothers to have physiologic childbirth by controlling pain and labor management based on their perception.
Background
With the increase of cesarean sections all over the world, researchers have become more interested in the mental mechanisms which affect mothers' tendency toward cesarean sections. Studies have indicated that many environmental factors have an impact on relieving the pain and fear of laboring mothers.
Methods
The comparisons made here, based on the existing literature about environmental factors and mothers' perception of these factors, have led to a re-reading of this subject. Thus a research project was carried out, using a structured questionnaire for the exploratory factor analysis methodology selected.
Results
The results indicate that the most important environmental factors which can encourage Iranian women toward physiologic delivery are "objective quality of life of delivery room (Eigenvalue of 7.400)", "attractive environmental stimuli (Eigenvalue of 4.267)", "environmental healthcare and physical health (Eigenvalue of 3.126)", "friendly atmosphere (Eigenvalue of 2.596)", "environmental vitality (Eigenvalue of 2.375)", "environmental privacy (Eigenvalue of 1.866)" and "tangible technology (Eigenvalue of 1.689)".
Conclusion
Considering that these factors play a substantial role, the study of mothers' perception of childbirth spaces is necessary. Promoting the environmental quality of the delivery room and using architectural solutions such as interior design and the general configuration can help mothers, husbands and medical staff better manage childbirth and thus have a positive impact on the rates of physiologic delivery.

Background
Comparison of the performance of a conventional, Anger-system, general-purpose SPECT/CT (AnyScan SC FLEX) vs. an Anger-system dedicated cardiac SPECT (CardioC) camera for gated myocardial perfusion imaging.
Method
Fifty patients were enrolled into the study. Of these, myocardial perfusion scintigraphy with 450 MBq SestaMIBI (Mediradiopharma) was performed after dipyridamole stress testing in 43, and at rest in the remaining 7 patients. ECG-gated SPECT acquisition was undertaken with both cameras, with a scanning time of 16 minutes. Within 45 to 60 minutes of the intravenous administration of the radiopharmaceutical, imaging was done first with the CardioC and then – after 30 minutes on average – with the AnyScan SC FLEX camera. The sensitivity of the systems (uptake of the radiotracer by the heart), severity of perfusion defects (SS), and parameters of left ventricular volume and wall motion (EF, EDV, ESV, SV, and cardiac mass) were determined quantitatively with both cameras. All these indices were then compared and the results were subjected to statistical analysis.
Results
Sensitivity (the scintillation counts recorded within the ROI cardiac projection) was 17.8% (median) higher with the AnyScan FLEX than with the CardioC camera (p < 0.001). There was no meaningful difference between the two cameras in assessing the severity of the perfusion abnormality (p > 0.1). The EF obtained after attenuation correction was significantly lower than without AC. The volume estimates significantly depended on the camera and reconstruction method (p < 0.001); especially, with the FLEX camera the EDV and SV estimates were significantly lower. Attenuation correction of the FLEX images resulted in the lowest estimated myocardial mass(p = 0.004 against the values obtained with CardioC).
Conclusions
The results support our initial assumption that when used formyocardial perfusion imaging, the performance of general-purpose, digital, hybrid SPECT/CT cameras and dedicated cardiac scanners (both with parallel-hole collimators) is similar in the case of conventional Anger-system devices.

Background: Chest radiography is the first choice for the investigation of cardiovascular and respiratory disease. Radiologic technologists are responsible for managing the radiation exposure to patients and providing adequate image quality according to the ALARA concept. This study is thus aimed to assess the Beliefs and behaviors of Radiographers on digital chest radiography in medical imaging departments. Method: A descriptive questionnaire-based study was carried out on 65 radiographers. By implementing the checklist, 390 digital chest radiographs were assessed during and after each procedure to evaluate the practice of radiographers. Results: The mean values of the radiographers’ knowledge and practice were 85.48 and 78.79 (out of 100), respectively. 5.38% of digital chest radiography (21 of 390) led to repetition. Conclusions: Radiographers should be properly trained on digital chest radiography for reducing the patient radiation dose and improve image quality and radiological interpretation.

In order to find out the status of organic pollutants in coal mine area of Ordos Basin in northwest China, we used an excitation emission matrix combined with parallel factor analysis to study the compositional characteristics and fluorescence intensity of dissolved organic matter (DOM) in mine water. In this way, we found that the DOM in the Mongolia-Shaanxi border mining area of Ordos Basin has four main components: two that resemble fulvic acid (C1/C3), a protein-like tryptophan substance (C2), and a protein-like tyrosine substance (C4). The fluorescence intensity of the fulvic acid-like component increased from 334.73 a.u to 440.33 a.u after treatment, and the fluorescence intensity of the protein-like tyrosine-component decreased from 330.18 a.u to 295.78 a.u. And then we investigated the removal efficiency of DOM and other pollution in the Caojiatan mine water treatment plant’s coagulation - filter – ultrafiltration process. In this process, the removal efficiency of the protein-like tryptophan components reaches 90%, while that of chemical oxygen demand / NO2− and the total organic carbon is about 50%. The removal efficiency of the Cu2+ and F−is less than 30%, and almost none of the protein-like tyrosine components, electrical conductivity, total dissolved solids, and NH4+. Thus, It’s proved that aliphatic hydrocarbons such as alkanes and cycloalkanes in mine water were removed in the treatment process, whereas macromolecular aromatic hydrocarbons and other groups were not removed. In the end, we put forward the ozone air flotation process, ozone effect makes the water of oxygen functional groups such as carboxyl, hydroxyl content increased, allowing more of the aluminum, iron, magnesium, and calcium ion complexing, precipitation, leading to desorption from the particulate organic matter, reduce the space steric hindrance and electrostatic repulsion, the effect of enhanced coagulation, Promote the condensation of particulate matter by means of adsorption bridge. This provides theoretical support for research on the source and fate of the carbon trajectory in the water cycle in a coal mine area and provides guidance on the removal of DOM from mine water.
