Published: March 2022

Background and objective: Hyoscine-N-butyl bromide (HBB) and paracetamol (acetaminophen)are widely used in emergency departments for abdominal pain and cramps. However, there is not enough data on the efficacy, safety, and superiority of each other in treating acute gastroenteritis (AGE) related abdominal pain and cramps. In this study HBB and paracetamol were compared for the treatment of abdominal pain and cramps related to acute gastroenteritis.

Materials and methods: The study was conducted in a tertiary university hospital emergency department as a prospective, randomized-controlled, and double-blind study. Intravenous (IV) 1000 mg paracetamol and IV 20 mg hyoscine-N-butyl bromide (HBB) were used to treat abdominal pain and cramps related to AGE. Visual analogue scale (VAS) was used to evaluate the degree of abdominal pain before and after treatment.

Results: HBB and paracetamol groups consisted of 123 and 158 cases respectively. In both groups, it was observed that the VAS score gradually decreased from the 0th hour to the 1st and 2nd hours (p<0.001).When comparing each time within itself, it was observed that HBB and paracetamol measurements had similar values (p>0.05). No severe side effects were observed in any of the patients.

Conclusion: HBB and paracetamol were used for symptomatic treatment in AGE patients presenting with abdominal pain and cramps. A significant reduction in pain and cramps was achieved in both patient groups. There was no difference between the two drugs in terms of treatment efficacy and side effects.

Published: March 2022

This paper explains about the importance of the cooperative societies in economic development. The aim is to discuss about the ways in which cooperatives can act as agents to the sustainable development of the community. Workers cooperative is an enterprise in which workers share in the profits and it is a business in which the workers retain a majority control of the enterprise control is exercised democratically on the basis of one person, one role, membership is open as for as possible to all workers and there are limit on the return to capital invested in the enterprises. Over the years, capital has hired lab our and treated it like an expendable factors of production same as any other factor, capital has explored labour and subjected it to the imperialism of profit maximization capital has claimed all the authority and all met profit while disclaiming full liability for the debts of the enterprise in case of liquidation. But now, worker want all that to change these days. This paper concludes that the cooperatives must achieve two interrelated goals, those are enhance the ability to work successfully and improve ability to service the members of the cooperatives, and remain an economically development, creative and competitive enterprises.

Authors: Shengjie Pan , Yinqiu Song , Hongyan Zhang
Published: March 2022

China's monetary policy has been progressively modified and transformed. In this study, the correlation between Chinese monetary policy and the stock market is investigated. The CSI 300 index, the trading volume of constituent stocks of the CSI 300 index, and M2 and R007 were selected to represent the stock market, quantitative monetary policy and price monetary policy, respectively. The transmission mechanism and regulatory effects of China's hybrid monetary policy on the stock market were studied. Stock prices and trading volume will rise when the People’s Bank of China (PBOC) puts money into the market; if the central bank raises interest rates, stock prices and trading volume will decline, and the regulatory effect of price-based monetary policy will be more significant than that arising from quantitative monetary policy. China's hybrid monetary policy has a dampening effect on stock prices and trading volume and effectively restrains the bubble of the financial market.

Papp, László: Religion of soldiers stationed in Carnuntum in the light of their epigraphical memories
In my study I examine the roman soldiers’ religion stationing at Carnuntum based on their inscriptions. I am looking for the connection between the soldiers’ profession, origin, where they were formerly stationed and the cults. Soldiers stationing at Carnuntum just like the ones deployed in other parts of the empire often presented their loyalty to the emperor through inscriptions. Mithras and Iuppiter Dolichenus were usually the favourites of many soldiers, but not for the ones’ who were stationing at Carnuntum, according to the inscriptions they preferred Silvanus and Nemesis instead. Although many images on gravestones are referring to after-life, it is hard to decide whether these images carried symbolic meanings or they were only used as ornamentation.
The need for a multi-pollutant approach to model the movement of pollutants in surface-water: A review of status and future challenges
Authors: Wali Saadu Umar
Published: March 2022

Significant research on surface water pollution modelling has been carried out over diverse landscapes has sought to explain the sources, transport, and surface water pollution. To date, surface water pollution studies have focused on nutrients, plastics, and chemicals. Consequently, the current review aims to identify and synthesise peer-reviewed literature about integrated contaminants modelling in surface water. Thus, highlighting that modelling potentially multiple sources of a pollutant from the surface water has remained a thought-provoking topic. Studies differed significantly in terms of the type of model application and procedures for reporting findings, making it challenging to separate clear trends and patterns. Accordingly, most studies agree that pollutants such as plastics and agrochemicals can have adverse consequences on surface water quality; these coincide with difficulties in modelling pollutant transport. Consequently, no regional or global estimates are available for the water pollution burden of flood-related pollution, considering the demonstrable modelling techniques, the significance of the concurrent impacts of surface water pollution by contaminants. Multi-pollutant approaches to modelling the potential sources of pollution and encourage protective behaviour are essential. Mainstreaming freshwater pollution concerns into planning strategies will also be needed to lessen anthropological contribution to surface water pollution. While the implementation of these models is constrained by lack of adequate field data, the model output must be analysed within the model inputs' uncertainty, data limitations and methodologically established surface water modelling principles from the literature.

Big data, small rule of law? About the call from executive professionals for constitutional reflection on big data applications in the Dutch police function

The promises of big data have reached the domain of safety and security. After these techniques proved their added value in the private sector, they soon reached the attention of the public sector. In this article we present the results of our interviews with 27 executive professionals of the Dutch police and the department of public order and safety of local governments. What are their expectations of big data? Their experience with big data varied. Our respondents gave expression to a basic positive attitude towards intelligence led policing and the chances that big data brings to it. But anticipation of working with big data was not free from discussion and the respondents stressed the need for securing privacy and other constitutional rights of citizens before big data applications are implemented in the police function. With that, our respondents strongly aligned with the international, academic call for a constitutional reflection about the application of big data withing the police function.
LA CIENCIA Y LA FE EN EL ORIGEN DEL UNIVERSO, LA VIDA Y EL HOMBRE
Authors: De la Barreda Nicolás Jouve
Published: March 2022

El ser humano, el único ser viviente autoconsciente y capaz de hacerse preguntas busca una explicación a su origen y al sentido del mundo en el que vive. Para ello cuenta con las «ciencias humanísticas », como la fi losofía, la teología y las «ciencias experimentales». Anida en el hombre un sentido de trascendencia que le ayuda a dar sentido a la existencia de todo y al mismo tiempo trata de desentrañar y relacionar las causas de lo que ocurre en la naturaleza con sus efectos. Ambos campos poseen sus métodos específi cos de análisis y bajo el «principio de demarcación», quedan delimitados sus ámbitos propios de actuación. Ciencia y religión no se superponen ni contradicen, sino que se complementan para dar satisfacción a las grandes preguntas. La ciencia nos permite explicar el cómo de los fenómenos naturales mientras que la religión nos da una explicación de la fi nalidad y el signifi cado del mundo. Tras analizar el modo en cómo se debe abordar el estudio de la realidad del mundo que nos circunda, en este capítulo nos centramos en los datos actuales sobre el origen del universo, la vida y la vida humana. Como conclusión afi rmamos la idea de que desde la aparición de la materia y su evolución hasta la aparición del hombre, con sus evidentes diferencias con el resto de las criaturas, todo es producto del logos previsto por el Creador.

Para hacerlo, nos detenemos en la escolástica y desgranamos algunas de sus características fundamentales, estudiamos a la Escuela de Salamanca y su relación con la ciencia económica moderna y nos ocupamos de las relaciones entre los autores grecolatinos y los del Renacimiento, todo ello sin obviar algu­nas de las enseñanzas de los escolásticos que podrían seguir siendo válidas en nuestros días e identificar cuáles de los autores del medievo podrían seguir siendo leídos en la actualidad.
Hombre y naturaleza: aproximación a la dicotomía
Authors: Arévalo Morales Marco Tulio
Published: March 2022

Pareciera que el hombre se encuentra enfrentado a la naturaleza que produce una oposición o lucha entre ambos, la cual llega a la actual crisis ambiental. La razón de esto podría ser la separación que Descartes introdujo en las sustancias finitas y que distingue la res extensa y la es cogitans. Esto llevó las cosas a un enfrentamiento dicotómico. Lo anterior también se apoya en el hecho de que el cuerpo se asocia a la naturaleza o es en nosotros dicha naturaleza —por la extensión— y el alma espiritual Descartes la ve como equivalente a la o sustancia pensante. Por ello se sesga la idea del hombre como dividido en una lucha interior entre su alma y su cuerpo, casi al estilo platónico. Mostar lo anterior es el propósito de este artículo.

Association between Non-alcoholic Fatty Liver Disease and the Severity of Coronary Artery Stenosis in Eastern Chinese Population
Authors: Wang Xiaohan , Shen Liang , Shen Yueyu , Han Feng , Ji Zizhong
Published: March 2022

Background: The present study aimed to investigate the relationship of non-alcoholic fatty liver disease (NAFLD) with the severity and extent of coronary stenotic lesions calculated by the Gensini score. In addition, the ability of Fibrosis-4 (FIB4) score to differentiate coronary artery calcification (CAC) and its severity is assessed. Methods: The current retrospective study was performed on a total of 342 patients examined between January and December 2016 in an affiliated hospital of Jiaxing University, Zhejiang, China. The study used liver ultrasonography for the assessment of NAFLD. Furthermore, the FIB4 and Gensini scores were used to predict hepatic fibrosis risk and the severity of coronary stenotic lesions. Results: The present study revealed that the serum levels of triglycerides, fasting glucose, alanine aminotransferase, and uric acid were significantly higher in patients with NAFLD than in participants without NAFLD (P < 0.001, P < 0.001, P = 0.032, and P = 0.002). Moreover, cases with NAFLD had a higher percentage of diabetes mellitus and hypertension (P < 0.001 and 0.001) than those without NAFLD. It was noted that the level of high-density lipoprotein was lower in patients with NAFLD than in participants without NAFLD (P = 0.006). In addition, we observed that the Gensini score was higher in patients with NAFLD than in participants without NAFLD (P = 0.033). It was found that 27.3%, 25.8%, 45.7%, and 56.3% of the participants had NAFLD in control, single, double, and multi lesion groups, respectively, and the difference was statistically significant (P = 0.008). The number of diseased vessels in patients with severe NAFLD was higher than in the control group (P < 0.001). It was also evident that the number of affected vessels significantly increased (P = 0.010 and P = 0.001) with the stages of NAFLD predicted by the FIB4 and Gensini scores. Furthermore, the Gensini score in patients with moderate and severe NAFLD was higher than in the control group (P = 0.013 and P = 0.019). We also conducted univariate logistic regression analyses to examine the relationship of CAC with FIB4 scores, and it was not significant (P = 0.191). Conclusions: The present study showed a positive relationship between NAFLD severity and coronary stenotic lesions in the eastern Chinese population. Furthermore, it was found that the higher the degree of FIB4 score, the higher the risk of CAC in patients with NAFLD. Therefore, assessing NAFLD severity using the FIB4 score may be useful for differentiating the patients at a higher risk of CAC. However, further prospective studies are required to establish the link between the FIB4 score and CAC.

Published: March 2022

This paper brings findings of recent malacological research (2013) and earlier mostly unpublished data about malacofauna of the Karlštejn National Nature Reserve (abbreviated as NNR) (Czech Republic, Central Bohemia, Bohemian Karst Protected Landscape Area). A total of 89 mollusc species (76 terrestrial snails, 5 freshwater snails, 8 bivalves) were recorded. The mollusc fauna of the NNR represents 35% of the total of 251 mollusc species found in the Czech Republic. The studied area comprises of very diverse habitat types with various and rich mollusc communities. Forest snails are dominating (38%) followed by species of the open steppes (27%). 28 species belong to endangered Red List species of the Czech Republic. Critically endangered Helicopsis striata and endangered Chondrina avenacea, Truncatellina claustralis and Zebrina detrita belong to the species of dry and open habitats. Helicopsis striata is probably extincted in most of localities in the Bohemian Karst. Its presence in the NNR was not confirmed. Bohemian Karst holds most of populations of Chondrina avenacea in the Czech Republic and the most of findings are situated in the Karlštejn NNR. Zebrina detrita inhabits here isolated site in Bohemia, where it was probably introduced in the past. Four new sites of the Holocene optimum relict Truncatellina claustralis were found.
A Procedure for the Comparative Evaluation and Preliminary Design of Marine Propulsors
Authors: Coney William B.
Published: March 2022

A systematic procedure for the design of a class of marine propulsors is described. This class of propulsors includes traditional propellers, ducted propellers, contra-rotating propellers, vane-wheel propulsors, and propellers operating with pre-or post-swirl stators. The topic of optimum propulsor load distributions is discussed. An algorithm for the determination of optimum radial circulation distributions for this class of propulsors is presented. This algorithm is incorporated in a vortex-lattice, lifting-line model for lightly to moderately loaded marine propulsors. This computer model also incorporates algorithms for the determination of minimum propeller chord lengths and thicknesses, as well as for the determination of optimum values of propeller rpm and diameter. Parametric studies and comparisons of various propulsor configurations can be readily carried out under the described model. A comparative study of marine propulsor alternatives for a given application is presented.
An Analysis Method for a Ducted Propeller with Pre-Swirl Stator Blades
Authors: Hughes Michael J. , Kinnas Spyros A.
Published: March 2022

A method is developed to analyze the flow around a ducted propeller operating in combination with a set of pre-swirl stator vanes. The method uses a boundary element method to solve for the flow around the duct and the hub and a lifting surface vortex lattice method to solve for the flow around the propeller and stators. The three-dimensional flow around the duct/hub, propeller, and stators is computed separately with the interactions between them being accounted for in an iterative manner. The interactions between the duct and the stators and between the duct and the propeller are treated in a non-axisymmetric manner. However, only the circumferentially averaged interactions between the propeller and the stators are considered. Using this method, a duct and set of stators are designed to operate efficiently with an existing propeller. This model was then built and tested in the MIT water tunnel at a variety of stator pitch angles. Comparisons are made between the theoretical and experimental values for the forces on the duct, propeller, and stators. A very good agreement is achieved in the region of the attached flow.

After these modifications, cavitation performance and pressure pulses have been evaluated for various practical propellers. Finally, the possibility to use PUF3A as a design tool has been investigated.

Los libros, las bibliotecas y las mujeres juegan papeles similares e invisibles durante los conflictos bélicos. La labor social de las bibliotecas es ampliamente conocida, siempre al rescate de la sociedad. Lo hemos visto en las distintas crisis que hemos ido atravesando en lo que llevamos de siglo. A las mujeres se les atribuye las consabidas labores de apoyo y cuidados. Y, por otro lado, también en paralelo, ambas sufren consecuencias terribles y devastadoras.

Single molecule localization microscopy (SMLM) detects and locates sparsely luminous single fluorescent molecules to achieve super-resolution imaging at nanoscale spatial resolution. In order to improve the temporal resolution, it is necessary to increase the density of the simultaneously emitting molecules. However, with the increase of the density, the point spread function (PSF) of different molecules will overlap severely on the detector, resulting in reduced spatial resolution, especially for three-dimensional (3D) SMLM. To solve this problem, a high density 3D-SMLM imaging method based on orthogonal astigmatism is proposed. Analysis and numerical simulation study for the method are carried out and presented. The main idea of the proposed orthogonal astigmatic method is to split the collected fluorescence in a SMLM microscope into two beams, each of which passes through a separate channel with a cylindrical lens and arrives at a specific region on the same detector. The two cylindrical lenses have the same optical parameters, but their orientations are set to be orthogonal to each other. They are used to obtain both positive and negative astigmatic PSF images of the same fluorescent molecule. Then, a linear projection model of the imaging process is established, and the 3D localization of the fluorescent molecules is realized by using a compression sensing algorithm. The results show that the two orthogonal cylindrical lenses produce a pair of astigmatic PSFs for one single molecule so that different PSF pairs between different molecules have lower mutual correlation, and thus the 3D localization accuracy for high density imaging can be significantly improved as compared with traditional astigmatic method, in which one single cylindrical lens is used. The larger the defocusing degree, the greater the shape difference between the two astigmatic PSFs is, and the more obvious this advantage.

With the development of underwater detection and communication technology, the traditional magnetic measurement model cannot meet the requirements for high precision and high efficiency modeling. In order to solve this problem, according to the integral model of ship magnetic field, we comprehensively analyze the discretization error caused by the composite middle rectangular and Gauss-Legendre integral remainders generated by discretizing the integral model into the magnetic dipole array model, the algorithm error, the fitting error caused by the model simplification, the model error, etc. and we also use these research results to analyze the model applicability conditions. Then based on the correlation between model error and parameters as well as accuracy and computational complexity, the multi-objective optimization problem is constructed. The NSGA-II algorithm is used to solve the multi-objective function, and the optimal solution set with balanced accuracy and complexity is obtained. The selection rules under the different requirements for accuracy and complexity are proposed. In order to ensure the effectiveness of the results, the model is simulated by using the actual submarine data on the basis of the hybrid model of ship magnetic field. The relationship between the distance to reach the applicable range of the model and the number of magnetic dipoles is obtained through the simulation analysis of the submarines with uniform and nonuniform magnetic field, and the simulation results are compared with the existing research results to ensure the effectiveness of the simulation results. At the same time, under the condition of ensuring the applicability of the model, the results obtained in the multi-objective optimization process based on NSGA-II algorithm are of high computational efficiency and accuracy. Therefore, this method has good engineering application value.

The holding voltage of electrostatic discharge (ESD) protecting structure is the critical parameter to determine the latch-up performance of the protecting device, but the thermal change of ESD device parameters lead the protecting device to suffer latch-up risk at high ambient temperature. In this paper, the holding characteristics of the ESD protecting device at various ambient temperatures ranging from 30 ℃ to 195 ℃ are studied. The investigated ESD structure is the N-channel metal oxide semiconductor (NMOS) transistors fabricated with the 0.18 μm partially depleted silicon-on-insulator process. The ESD characteristics of the device are measured by the transmission line pulse test system at different ambient temperatures. The test results show that the holding voltage (VH) decreases with temperature increasing. The TCAD simulation is carried out to support and analyze the experimental results, and the same trend of VH versus temperature is obtained. Through the analysis of simulation results and theoretical derivation, the underlying physical mechanisms related to the effects of temperature on VH and holding current (IH) are discussed in detail. When the drain is subjected to the same current pulsing and the Source and Body are both grounded, the distributions of current density, electric potential, and injected electron density of NMOS at various temperatures are extracted and analyzed. When the Drain, Source, and Body are all grounded, the distributions of the electrostatic field at various temperatures are extracted and analyzed. The distribution of electric potential in NMOS indicates that the voltage drop on the Drain-Body junction (VDB) is affected by ambient temperature significantly, and the variation of VDB dominates the variation trend of VH with temperature increasing. The reducing electrostatic field and increasing injected electron density with temperature decreasing contribute to the decreasing of VDB. The trend of IH and parasitic Body resistance (RBody) weakens the temperature dependence of the VH. The current gain of parasitic bipolar transistor (β) decreases with ambient temperature rising, which is the main contributor to the decreasing of IH. Therefore, increasing IH and RBody is helpful in reducing the temperature dependence of the latch-immune ESD protection structure.

Post-mortem magnetic resonance imaging (MRI) provides the opportunity to acquire high-resolution datasets to investigate neuroanatomy and validate the origins of image contrast through microscopy comparisons. We introduce the Digital Brain Bank (open.win.ox.ac.uk/DigitalBrainBank), a data release platform providing open access to curated, multimodal post-mortem neuroimaging datasets. Datasets span three themes—Digital Neuroanatomist: datasets for detailed neuroanatomical investigations; Digital Brain Zoo: datasets for comparative neuroanatomy; and Digital Pathologist: datasets for neuropathology investigations. The first Digital Brain Bank data release includes 21 distinctive whole-brain diffusion MRI datasets for structural connectivity investigations, alongside microscopy and complementary MRI modalities. This includes one of the highest-resolution whole-brain human diffusion MRI datasets ever acquired, whole-brain diffusion MRI in fourteen nonhuman primate species, and one of the largest post-mortem whole-brain cohort imaging studies in neurodegeneration. The Digital Brain Bank is the culmination of our lab’s investment into post-mortem MRI methodology and MRI-microscopy analysis techniques. This manuscript provides a detailed overview of our work with post-mortem imaging to date, including the development of diffusion MRI methods to image large post-mortem samples, including whole, human brains. Taken together, the Digital Brain Bank provides cross-scale, cross-species datasets facilitating the incorporation of post-mortem data into neuroimaging studies.
