Assessing the Accidents at Work by RC(M) Association Model Analysis

The occupational injuries, diseases and deaths result in high economic costs to individuals, employers, governments and society. If a State aspires to an economy aimed at productivity and efficiency, workers’ welfare, research and regulation in the field of safety at work and the relative reduction of accidents at work are fundamental. Currently, in Italy, the law of reference is the legislative decree 81/2008 ((known as the Testo Unico Sicurezza Lavoro), which revised and integrated most of the decrees from the '50s onwards, by incorporating the EU Directives coordinated in a single piece of legislation that includes specific sanctions against defaulters. The aim of this work is to verify whether preventive policies, mandatory in Italy with the legislative decree 81/2008, have highlighted a real decrease in accidents at work. The analysis has been conducted using RC(M) model association, in particular the use of a summary measure and a graphical representation has been proposed to verify if association between the variables geographical area (North, Center, South and Isles of Italy) and years (from 2008 to 2018) exists. Specifically, the results have not highlighted a significant reduction of the number of accidents from 2008 to nowadays.
Time Series Changes in Fish Assemblages and Habitat Structures Caused by Partial Check Dam Removal

Despite a steep increase in dam removal projects, there are few studies on the biophysical responses to dam removal. In this study, we evaluated the short-term (1.5 years) and long-term (5.5 years) effects of partial check dam removal on fish assemblages and their habitats. First, the habitat preferences of fish were examined at a channel unit scale: pools, rapids, and side channels satisfied the seasonal habitat requirements of the fish assemblages. Partial check dam removal increased the abundance of these habitats and diversified the habitat structures owing to the sediment release from the dam; in contrast, the bedrock distinctly decreased 1.5 years after dam removal. However, 5.5 years after dam removal, the bedrock proportion increased, and the habitat structures were simplified again owing to the re-transportation of sediments. Similar temporal changes were also determined through a reach-scale analysis with a change in the bed materials. Anadromous Oncorhynchus masou began to spawn and recolonize in the upstream section of the dam after the dam removal, causing similar assemblage compositions between the downstream and upstream sections. The abundance of Salvelinus malma and Noemacheilus barbatulus toni in the upstream reaches decreased over time after the dam removal. The temporal changes in the biophysical responses suggest that long-term monitoring is indispensable for the reliable evaluation of dam removal effects.
Muslim Treatment of Other Religions in Medieval Bengal

This research analyzes Muslim treatment of other religions in Medieval Bengal from 1204 to 1757 CE with a special reference to Muslim rulers and Sufi saints. The study is based on historical content analysis using a qualitative research design. The study shows the Muslim sultans and Mughals in the medieval period played a vital role in promoting interreligious harmony and human rights in Bengal. In addition, the Muslim missionaries and Sufis served as a force against religious hatred in society. The Muslim sultans and Mughals applied liberal and accommodative views toward non-Muslims. They did not force non-Muslims to accept Islam. Muslims and non-Muslims were integrated society, and they enjoyed full socioeconomic and religious rights. Moreover, Sufis conducted various approaches toward Muslims and non-Muslims as well. They promoted the message of equality and moral conduct among the diver’s faiths of the people. They also applied liberal, syncretic, and accommodative attitude in attracting non-Muslims to Islam in Bengal. The study concludes that most rulers were sympathetic and cooperative in dealing with the people of other religions.
Thermogravimetric kinetics of thermotropic copolyesters containing p‐oxybenzoate unit by multiple heating‐rate methods

Two series of thermotropic liquid crystalline copolyesters containing mainly the p-oxybenzoate unit were studied by thermogravimetry to ascertain the kinetic parameters of their thermal degradation by six multiple heating-rate techniques for the first time. The two copolyesters are (1) poly(p-oxybenzoate-co-ethylene terephthalate-co-vanillate) and (2) poly(p-oxybenzoate-co-2,6-oxynaphthoate). The effect of copolymer composition, degradation stage, and test atmosphere on the three kinetic parameters of the thermal degradation in the weight loss range from 5 to 70% is discussed. Comparison of the multiple heating-rate techniques with single heating-rate techniques for calculating the kinetic parameters of thermal degradation was made. The respective activation energy, order, and natural logarithm of the frequency factor of the thermal degradation in nitrogen for the poly(p-oxybenzoate-co-ethylene terephthalate-co-vanillate)s are between 180 and 230 kJ/mol, between 2.0 and 5.0, and between 28 and 38 min -1 for the first degradation step and between 250 and 390 kJ/mol, between 6.4 and 7.6, and between 38 and 64 min -1 for the second degradation step of the poly(p-oxybenzoate-co-ethylene terephthalate-co-vanillate)s with the unit-B content in the range of 70-75 mol %. The respective activation energy, order, and natural logarithm of frequency factor of the first degradation stage for the poly(p-oxybenzoate-co-2,6-oxynaphthoate) (Vectra) are between 380 and 570 kJ/mol, between 2.0 and 3.1, and between 55 and 68 min -1 in nitrogen and between 160 and 210 kJ/mol, between 0.8 and 1.8, and between 25 and 32 min -1 in air. The best methods of calculating the kinetic parameters of the thermal degradation for the copolymers are suggested.
Identification of the Origins of Vadose-Zone Salinity on an Agricultural Site in the Venice Coastland by Ionic Molar Ratio Analysis

Saltwater contamination seriously affects water quality and land productivity of reclaimed farmlands along the Venice Lagoon, Italy. To characterize the hydrogeochemical dynamics involved in this phenomenon, a three-year study was carried out in an experimental field located at the southern margin of the Venice Lagoon. Soil matric potential, quality of soil pore water and groundwater, and soil physical and chemical properties were monitored at five monitoring stations. Relationships between Cl−, Na+, Mg2+, Ca2+, K+, SO42−, Br− ionic concentrations, and electrical conductivity of the water samples with the soil characteristics (e.g., texture, exchangeable cations) were investigated. Soil water flux direction was calculated and related to ion concentrations. Moreover, specific molar ratios (Mg/Ca, Na/Cl, Cl/Br, and SO4/Cl) were calculated to identify the main drivers affecting salinity in the field. The study confirmed that the experimental site was strongly affected by soil and water salinity, and two major contamination dynamics were identified. The first one was mainly driven by seawater intrusion from the near lagoon and salty watercourses, while the second was derived by the interactions between the peaty soil and salts that were originally in place, since the area was only reclaimed a few decades ago. The latter highlighted the potentiality of the experimental field to become an acidic sulfate environment. Ionic ratios were implemented and proved to be an important tool for the identification of salinity origin.
Grain Yield and Mineral Element Composition of Maize Grown on High Phosphorus Soils Amended with Water Treatment Residual

ABSTRACT The potential for phosphorus (P) movement from poultry-litter amended soils into surface waters heightens the need to manage elevated P concentrations. Amending high P soils with aluminum (Al) rich drinking water treatment residue in a greenhouse study reduced water extractable P levels and induced P deficiency in container grown wheat. Objectives of the current investigation were to determine the effect of water treatment residue on grain yield, leaf and grain mineral nutrient concentrations in corn (Zea mays L.) grown under field conditions and to examine pH, water and Mehlich 3-extractable P, and 0.01 M calcium chloride extractable Al in the amended soils at two sites. Poultry litter was amended with 0, 5.6, and 11.2 Mg ha− 1 of water treatment residual and applied to two sites prior to planting with corn in 1998. Additional rates (16.8 and 33.6 Mg ha− 1) of water treatment residue were applied directly to half of each plot on site I in 1999. Results indicated that water treatment residue application did not adversely affect corn grain yields or alter concentrations of mineral nutrients in leaves and grain. Water and Mehlich 3-extractable P and calcium chloride extractable Al concentrations were unchanged with water treatment residue applications in both years on both sites. Further studies are needed concerning optimal annual dosages and long term loading rates for direct soil application of water treatment residue to reduce soluble phosphorus.
1H MR Spectroscopy of Fine-Needle Aspiration Biopsy Specimens for the Discrimination of Breast Cancer.

Purpose To determine whether MR spectroscopic assessment of fine-needle aspiration (FNA) biopsy specimens from suspicious breast lesions could be used to improve the diagnostic utility of FNA biopsies for the characterization of breast lesions. Materials and Methods In this prospective study, a previously reported technique using high-spatial-resolution proton MR spectroscopy was modified and used to examine the utility of FNA biopsies in the evaluation of suspicious breast lesions. Tissue samples from 115 lesions (from 102 women; average age, 54 years) were excised by using FNA and core biopsies and were collected between September 7, 2012, and April 11, 2014. Histologic results from core biopsy specimens determined the lesions to be benign (n = 55), invasive ductal carcinoma (n = 51), invasive lobular carcinoma (n = 5), or ductal carcinoma in situ (n = 4). Measures of phosphocholine (PC), glycerophosphocholine, and choline relative to each other and to total creatine (tCr) were obtained from usable spectra. Planned comparisons among lesion groups were carried out using t test contrasts, and differences of each contrast level from zero were judged significant when the two-tailed P value was less than . 05. Results Of the 115 samples, 69 (60%) yielded no usable MR spectra. Analysis of the 46 with usable spectra found that only the difference in PC/tCr between benign and cancer lesions was statistically significant (P = .028). Conclusion Given that 60% of FNA biopsy specimens yielded no usable spectra and that results were largely inconclusive when derived from usable spectra, the combined MR and FNA technique, as modified and implemented in this study, is of little value for detection and diagnosis of breast cancer.Keywords: Breast, MR-Spectroscopy, Neoplasms-Primary© RSNA, 2020.
Nanocomposite Hydrogel with Tantalum Microparticles for Rapid Endovascular Hemostasis

Endovascular embolization to treat vascular hemorrhage involves pushing coil‐shaped metal wires into the artery repeatedly until they are densely packed to slow the blood flow and clot. However, coil embolization is associated with high rebleeding rates, unpredictable economics and, most importantly, they rely on the patient's ability to make a clot. These issues are exacerbated when the patient is anticoagulated or coagulopathic. A novel bioengineered tantalum‐loaded nanocomposite hydrogel for gel embolic material (Ta‐GEM) that can be rapidly delivered using clinical catheters for instant hemostasis regardless of the coagulopathic state is reported. Ta‐GEM formulation is visible by most of the clinically available imaging modalities including ultrasound, computed tomography, magnetic resonance imaging, and fluoroscopy without significant artifact. In addition, Ta‐GEM can be retrieved, allowing temporary vascular occlusion, and it can be used to rescue cases of failed coil embolization. Ta‐GEM occlusion of first‐order arteries such as the renal artery and iliac artery in a swine model is found to be safe and durable; by 28 days, 75% of the injected Ta‐GEM in the arterial lumen is replaced by dense connective tissue. Altogether, this study demonstrates that Ta‐GEM has many advantages over the current technologies and has potential applications in clinical practice.
Sharing travel related experiences on social media – Integrating social capital and face orientation

Tourists can share their travel experiences or related information freely through social media platforms. The purpose of this research is to explore the factors associated with sharing travel related experiences on social media by travellers in the context of social capital theory and person-context interaction theory. Data were collected among consumers in Malaysia using a structured survey; 423 responses were generated. The findings show that the social capital dimensions (social ties, trust, reciprocity and shared vision) positively impact sharing intention on social media while identification doesn’t impact the sharing intention. The results also partially support the hypothesis that protective face orientation negatively influences social capital dimensions and sharing intention while acquisitive face orientation positively influences them. The authors shed light on the construction of social capital dimensions and face orientation and the relative importance of the sharing intention on social media.
Comparison analysis of decision tree and ensemble models in the classification of chronic kidney diseases

The world is now in the era of big data and processing, and exploring the data has become one of the significant challenges. Hence, researchers have done a lot to analyse these data in the health sector to enhance disease detection and classification using artificial intelligence and ML principles. Kidney disease is one of the terrible conditions in which its late detection has sent many people to untimely graves. ML classifiers have been employed in many dimensions to classify heart disease, but, existing works have not explored the variants of each method for selection of best model parameters. An attempt is being made in this research to study the behaviour of three (3) variants each from two(2) tree-based models in the classification of Kidney Disease. Three of the variants are Complex, Medium and Simple models of Decision tree classifier and the other one are Boosted, Bagged and RUSBoosted of Ensemble Classifiers. Using MATLAB for implementation, the model performance established that the accuracy of Ensemble Classifier (Bagged tree model) is the best, concerning the speed, Decision tree (Complex and Simple tree models have the same and highest value). Hence, the two are the best. In terms of training time, Decision tree(Simple tree) has the least time and therefore the best.
The Influence of understanding basic training participants of teacher civil servants about ASN function to teacher performance in learning services

The purpose of this study was to determine the effect of Latsar CPNS participants' understanding of the function of ASN (Variable X) on the performance in learning services (Variable Y). Gibson and Spencer stated that performance is influenced by variables of employee knowledge and understanding. The research hypothesis is suspected that there is an influence of variable X on Y. The research was conducted using quantitative methods. The population was 1851 people. Samples based on the Slovin formula were taken as many as 329. The instrument tested with SPSS 18 which is declared valid and reliable. Data normality test, with the Kolmogorov-Smirnov test with a value of 0.2 for Variable X and 0.1 for Variable Y less than p 0.05, so the data for the two variables were normally distributed. Simple Linear Regression Test obtained a significance value (Sig.) of 0.012, smaller than the probability of 0.05, which means that there is a significant effect of variable X on variable Y. Furthermore, the Hypothesis Test is continued with the t test, and the t value is 2.524 greater than t table 1.6499 with R Square 0.019. The contribution of variable X to variable Y is only 1.9%. The contribution of other variables that affect the performance of CPNS teachers by 98.1% still needs further research. This study concludes that there is a positive influence on the understanding of Latsar CPNS teachers about the function of ASN on teacher performance in learning services.
Perturbation Theory for Nonuniform Fluids: Surface Tension

The Barker—Henderson perturbation theory for uniform fluids is extended to include nonuniform fluids. The surface tension for a Lennard‐Jones fluid is calculated by minimizing the free energy in the surface layer. Comparison with the corresponding experimentally obtained values of surface tension for argon shows that excellent agreement is obtained in the case of a Lennard‐Jones 12–6 fluid with values of the potential parameters determined from the second virial coefficient.
Broadening by strains of lines in the g‐parallel region of Cu2+ EPR spectra

Linewidths of the mI=−3/2 and −1/2 hyperfine lines in the g‐parallel region of several square‐planar copper complexes with oxygen ligands in frozen solutions have been measured at 2.6, 3.8, and 8.9 GHz. A theory has been developed in terms of distributions of molecular bonding parameters that satisfactorily accounts for the observed dependence of linewidths on mI and the microwave frequency. It has been found that distributions of the bonding parameters are strongly correlated, indicating that copper complexes when subjected to strains during freezing distort in a well‐defined, predictable manner. It is found that the mI=−3/2 line generally is narrowest near 6 GHz and the mI=−1/2 line near 2 GHz. By proper selection of the microwave frequency, improved spectral resolution can be obtained. Complexes with nitrogen ligands also have been examined. Proper selection of microwave frequency often permits observation of superhyperfine structure, and even when it cannot be seen, analysis of the linewidth variation.
Evaluation of Lead (II) Removal from Wastewater
Using Banana Peels: Optimization Study

The response surface methodology was used to investigate the removal of Pb (II) from an aqueous solution using banana peel with varying operating parameters in a batch mode. The central composite design was used to study the interactive effects of the operating parameters (initial concentration, pH of the solution, adsorbent dosage and the particle size). The banana peel was characterized by FTIR which showed the functional groups, while SEM and EDS were used to study morphology and elemental composition. The optimum removal of Pb(II) was 98.146 % at initial concentration 100 mg/L, pH 5, adsorbent dosage 0.55 g and particle size 75 μm. The deviation between the experimental and the model predicted percentage removal was 5.17 %. The analysis of variance showed that the regression model was significant with a low probability and the correlation coefficient R2 value of 0.9153. The results showed that the biosorption of Pb(II) was highly influenced by the pH and the adsorbent dosage, while the particle size had little effect on the biosorption process.
Chitosan/Carboxymethyl Cellulose Polyelectrolyte Complex Scaffolds for Pulp Cells Regeneration

Novel polyelectrolyte complex (PEC) chitosan/carboxymethyl cellulose (CMC) scaffolds are prepared using a freeze-dry process. The microstructure is characterized by SEM and the average pore diameters and internal porosities are calculated. The morphology and distribution of pulp cells on these three-dimensional scaffolds are investigated by SEM and confocal laser scanning microscopy (CLSM). The expression of osteonectin (ON) and dentin sialophosphoprotein (DSPP) is detected by reverse transcription polymerase chain reaction (RT-PCR). The scaffolds are then implanted subcutaneously into BALB/c mice. The addition of CMC to chitosan decreases the pore diameter and increases internal porosity. The pulp cells co-cultured in these PEC scaffolds show improved adhesion, spreading, cell capacity, and three-dimensional configurations compared to pure chitosan scaffolds. Based on the data obtained, the chitosan/CMC complex provides an improved scaffold material for pulp tissue engineering.
Knowledge about Human Papillomavirus and Cervical Cancer Prevention among Intern Nurses

Objective: Intern nurses will play an important role in the use of vaccination to prevent cervical cancer. This study assesses the knowledge about human papillomavirus (HPV) infection and cervical cancer prevention among intern nurses. Methods: We developed a questionnaire to investigate intern nurses' knowledge about HPV infection and cervical cancer prevention. Participants included 323 intern nurses from eight schools. Results: The effective response rate was 79.8%. Some (7.0%) knew that early-stage cervical cancer is commonly asymptomatic. Only 9.7% knew that infection is generally asymptomatic and 20.5% knew that vaccination has no major side effects. There were differences in gender, age, school type, and place of residence for several questions. Conclusions: This study indicates a low level of knowledge about HPV infection and cervical cancer prevention among intern nurses. Our findings highlight the need for more education in this topic to increase the knowledge of intern nurses.
Enhanced Energy Conversion Performance of a Magneto–Mechano–Electric Generator Using a Laminate Composite Made of Piezoelectric Polymer and Metallic Glass

Magneto–mechano–electric (MME) generators, which convert ubiquitous stray magnetic field into electricity, have attracted significant attention as a permanent power source for innumerable sensors. In this study, a MME generator based on magnetostrictive metallic substrate and piezoelectric polymer is reported. After the metallic glass sheets are stacked using adhesives, ferroelectric poly(vinylidene fluoride‐co‐trifluoroethylene) is spin‐casted onto Metglas lamination. The fabricated MME generator harvests an output peak voltage of ≈12.5 V under the applied alternating current magnetic field of 7 Oe at 38.2 Hz. A high magnetoelectric voltage coefficient of 910.14 V cm−1 Oe−1 obtained from the energy device is higher than those reported earlier in inorganic and polymeric piezoelectric components‐based MME generators. Moreover, finite element analysis using the multiphysics simulation is carried out to theoretically investigate the magnetoelectric energy harvesting of the fabricated MME generator. This research results achieve low cost, mechanical stability, eco‐friendliness, and high performance for MME generators, which is anticipated to provide a future direction for magnetoelectric energy harvesting.
Contingency Analysis to Evaluate the Robustness in Large-Scale Smart Grids: Based on Information Security Objectives and Frequency Stability

Smart grids (SGs) are attracting attention as high value-added platforms, which mass-produce new business models through real-time information sharing. However, the open-ended information structure of SGs increases the risk of exposure to cyberattacks through the creation of multiple communication access points. In a power system where a real-time balance of supply and demand is essential, cyberattacks result in cascading failures leading to power outages. Therefore, this paper proposes a method to evaluate the robustness of large-scale SGs against cybersecurity disturbances. The proposed evaluation method established a hierarchy quantification technique considering the structural characteristics of SGs. With respect to the cyber hierarchy, relevant standards (NERC CIP, NIST FIPS) were applied to classify the grades of information security risk. In the case of physical hierarchy, the power system was calculated by using optimal power flow and analyzed the frequency stability. This study was aimed at identifying the vulnerabilities in the physical topology aspect of intelligent power systems due to cybersecurity disturbances.
