Authors: Feng Zhanxia , Chang Zongyu , Deng Chao , Zhao Lin , Chen Jia , Zhang Jiakun , Zheng Zhongqiang
Published: October 2021

Wave glider is an unmanned surface vehicle which can directly convert wave energy into forward propulsion and fulfill long-term marine monitoring. Previous study suggested that the wave motion and stiffness of restoring springs mounted on the hydrofoil are main factors affecting the propulsion performance of wave glider. In this paper, the dynamic responses and nonlinear characteristics of underwater propulsion mechanism considering the nonlinear stiffness of restoring springs are investigated based on a fluid-rigid body coupled model. Firstly, the models of propulsion mechanism with different kind of restoring spring are proposed, and the linear and nonlinear characteristics of restoring spring are considered. Then, a fluid-rigid body coupled model of wave glider is developed by coupling the rigid body dynamics model and hydrodynamic model. Dynamic responses are simulated by numerical analysis method and the nonlinear characteristics with different restoring springs are illustrated by time/frequency domain motion response and phase diagram analysis. The effects of wave excitation frequency and wave heights on the propulsion performance of wave glider are analyzed. The results show that, multi-frequency responses occurred in propulsion system. And the study suggests that the nonlinear restoring spring on the hydrofoil can be suitable for different sea condition and better propulsion performance can obtained than linear stiffness spring, which provides a reference for developing propulsion mechanism with high performance in complex marine environment.
Pose Measurement and Assembly of Spacecraft Components based on Assembly Features and a Consistent Coordinate System
Authors: Chen Shuqing , Li Tiemin , Jiang Yao
Published: October 2021

To assemble spacecraft automatically and precisely, it is vital to measure the relative spatial pose (position and orientation) of the assembly features of the spacecraft components before assembly. For large-scale spacecraft components, the global measurement method is mainly utilized to guide assembly control, and its accuracy and efficiency have ultimately failed to meet requirements. To address this issue, a novel measurement method is proposed. Since the goal is to measure the relative spatial pose of the assembly features of the spacecraft components, the proposed method measures it directly to ensure the consistency of the measurement and assembly coordinate system. This method has the advantage of high precision because it can reduce the influence of structural parameter errors and is not limited by the scale of the spacecraft components. In addition, it requires only one offline calibration, which significantly improves the efficiency of online measurement and assembly. Taking the control moment gyroscope (CMG) assembly task as an example, a measurement system and its corresponding calibration device are designed and developed. After calibration by the calibration device, the measurement system is mounted on the assembly features of the CMG to measure the relative spatial pose between the assembly features of the CMG and the assembly features of the mounted base (MB). Finally, six assembly experiments are completed according to the measurement results. The experimental results show that this method has high accuracy and can guide the robot to achieve high assembly accuracy, satisfying the assembly requirements of typical spacecraft components.
A combined water hammer protective method for optimizing the volume of the air vessel in water supply systems
Authors: Lyu Jiawen , Zhang Jian , Wang Xingtao , Xu Tingyu
Published: October 2021

An air vessel, as an effective and reliable water hammer protective device, is widely used in long-distance water supply systems. However, the volume of the air vessel must be extra-large to guarantee security of the system, especially in a system with a high head and large flow. In this paper, to reduce the volume of the air vessel, a novel protective method combining an air vessel and over pressure relief valve was proposed and verified using a numerical simulation based on a practical project. In addition, the protection performance under the combined protective method was compared with the traditional method. The results show that the combined protective method can significantly reduce the volume of air vessel and exhibit a better protection performance. Furthermore, after analysis and optimization of the rule of opening and closing over the pressure relief valve, the valve should be opened in a short time to produce fast discharge so as to eliminate the large pressure rise rapidly. The duration of opening the over pressure relief valve has little effect on the maximum pressure. The closing time of the over pressure valve should be slow, as much as possible, to avoid producing large pressure wave.
Adsorption of Pb(II) cation from aqueous solutions by acid modified low-rank coal: An experimental study and simulation
Authors: Wang Penghui , Liu Wenli , Xu Hongxiang , Liu Guowei
Published: October 2021

An acid modified approach to enhance the adsorption capacity of low-rank coal (lignite) is proposed to reduce the risk of heavy metal ions within the wastewater. Adsorption kinetics, adsorption thermodynamics, adsorption coefficient and density functional theory DFT calculations were studied in this paper, respectively. The results indicate that the adsorption capacity of lignite was enlarged after HNO3 modification, and pseudo-second order kinetics model and Langmuir isothermal adsorption model can be used to describe the adsorption process. The surface chemical properties of lignite play a dominant role rather than the specific surface area and total pore volume in the Pb(II) cation adsorption process, and it is suggested that the adsorption of Pb(II) cation by raw lignite (RL) and modified lignite (ML) is mainly completed by chemical adsorption. The Fourier transform infrared spectroscopy (FTIR) characterization showed that the surface oxygen functional groups of lignite increased after modification. The results of interaction energies between the model molecule and Pb(II) cation show that Pb(II) cation and -C-O-C are most easily combined, followed by -COOH, and -C = O is the weakest.

Authors: Talavirya A. U. , Laskin M. B.
Published: October 2021

The purpose of the studyis to assess changes of toll fares usedon toll collection points. When toll road is operating in an urban environment, the operator is inevitably faced with the need to adaptintelligent transport system to the conditions of an ever-increasingvolume and changing composition of the traffic. Such changes havea direct impact on the capacity of the toll road, in particular at tollcollection points. The conducted research is aimed at analyzing the method of reducing the traffic load at the toll collection points duringpeak hours by making changes to the toll fares aimed at uniform distribution of traffic flow throughout the day. As an example, a tollcollectionpointonthe main roaddirectionof the Western High-SpeedDiameter toll road was chosen.

Materialsandmethods.A discrete-event simulation model developedin the AnyLogic software was used to assess the quality of operationandthroughputofthetollcollectionpoint.Thesoftwarehasa sufficientlevel of detail to reproduce the operation of the toll collection system,and allows managing all the necessary parameters of the system andtraffic flow. Analysis of the data obtained from the simulated model experiments was carried out using the statistical package R.

Results.As part of the study, the operational characteristics ofthe toll collection point, in particular its threshold capacity, were determined, and, if it was exceeded, the length of the emerging queue was determined. Taking into account the operator’s risks arising fromthe formation of a traffic congestion, an approach was proposed tochange the toll fare policy of the toll road by using a more flexiblefares based on dividing the day time fare into several time intervalsand using increasing coefficients for toll fare when paying for travelduring peak hours. Using the example of toll booth of the WesternHigh-SpeedDiameter,theincreasingcoefficientsofthecostoftravelata rush hour were considered, and the risks of reducing the operator’sincome from toll collection were assessed.

Conclusion.Based on the results obtained, an assessment of the effectiveness of the application of measures to change the existing tollfare policy, aimed at optimizing the traffic flow of a toll road, canbe carried out. In addition, such an analysis can be used to assessthe investment attractiveness of a project, develop a toll fare policy, increase income and other similar tasks. Further research can be aimed at increasing the economic indicators of toll road projects, and developing additional mathematical tools used in the formation of toll fare policy.

Authors: Sun Miao , Bao Wenchenyang , Huang Chengyu , Xia Ziyue , Zhang Changliang , Wang Guangxian , Wang Runxin , Li Jiangyu , Roux Shaun , Li Qian , Zou Dongmei , Ma Kai , Bao Xiaofeng
Published: October 2021

Background:

The brain-gut-microbiome axis has emerged as an important pathway
through which perturbations in the gut and/or microbial microenvironment can impact neurological
function. Such alterations have been implicated in a variety of neuropsychiatric disorders, including
depression, anxiety, and Alzheimer’s Disease (AD) and the use of probiotics as therapy for these
diseases remains promising. However, the mechanisms underlying the gut microenvironment’s
influence on disease pathogenesis and therapy remain unclear.

Objective:

The objective of this study is to investigate the effect of a novel probiotic formula,
BIOCG, on cognitive function and pathobiological mechanisms, including amyloid processing and
dendritic spine dynamics, in a mouse model of AD.

Methods:

BIOCG was administered for 3 months to 3xTg or 3xTg; Thy1-YFP AD mice and functional
outcomes were assessed via behavioral testing and electrophysiology. Mechanisms relevant
to AD pathogenesis including dendritic spine morphology and turnover, Amyloid Precursor Protein
(APP) processing and microglial phenotype were also evaluated. Finally, we sequenced fecal
samples following probiotic treatment to assess the impact on gut microbial composition and correlate
the changes with the above described measures.

Results:

Mice treated with BIOCG demonstrated preserved cognitive abilities and stronger Long-
Term Potentiation (LTP), spontaneous Excitatory Postsynaptic Currents (sEPSC), and glutamate-induced
LTPs, indicative of functional and electrophysiological effects. Moreover, we observed attenuated
AD pathogenesis, including reduced Amyloid Beta (Aβ) burden, as well as more mature dendritic
spines in the BIOCG-treated. Our finding of changes in microglial number and phenotype in
the treatment group suggests that this formulation may mediate its effects via attenuation of neuroinflammation.
Sequencing data confirmed that the gut microbiome in treated mice was more
varied and harbored a greater proportion of “beneficial” bacteria.

Conclusion:

Overall, our results indicate that treatment with BIOCG enhances microbial diversity
and, through gut-brain axis interactions, attenuates neuroinflammation to produce histologic and
functional improvement in AD pathogenesis.

Authors: Jamali Fatima , Aldughmi Mayis , Khasawneh Mohammad W , Dahbour Said , Salameh Alaa A , Awidi Abdalla
Published: October 2021

Background

Parkinson disease (PD) is a neurodegenerative disorder associated with a broad spectrum of motor and nonmotor symptoms. Any proposed cure needs to address the many aspects of the disease. Stem cell therapy may have potential in this regard as indicated in recent preclinical and clinical studies.

Objective

This protocol aims to examine the safety and therapeutic benefit of human Wharton jelly-derived mesenchymal stem cells (WJ-MScs) and their derivatives, neuronal stem cells (NSCs) in PD.

Methods

This clinical trial is a double-arm, single-blinded, phase I-II interventional study. Participants have been allocated to 1 of 2 groups: one receiving allogeneic WJ-MSCs alone, the other receiving NSCs and WJ-MScs. Participants are being followed-up and assessed over a period of 6 months. To assess safety, an incidence of treatment-emergent adverse events (TEAEs) tool tailored for PD is being used immediately and up to 6 months after treatment. For efficacy assessment, a number of factors are being used, including the gold standard severity test and the Unified Parkinson Disease Rating Scale. In addition, the following standardized assessments for different common symptoms in PD are being included: motor (both subjectively and objectively assessed with wearable sensors), sensory, quality of life and psychological well-being, cognition, and sleep quality. Furthermore, immune-modulatory cytokines and neuronal damage versus regeneration markers in PD, including the neuronal protein linked to PD, α-synuclein, are being monitored.

Results

Ten patients have been enrolled in this study and thus participant recruitment has been completed. The study status is active and beyond the recruiting stage. Study chart implementation, data collection, and analysis are ongoing.

Conclusions

The combination of NSCs and MSCs in PD may be useful for harnessing the best of the immunomodulation and neural repair characteristics of these cell types. The tailored comprehensive and scaled TEAEs and the variety of evaluation tools used enables a comprehensive assessment of this cellular therapy treatment protocol. A consideration of this expanded tool set is important in the design of future clinical studies for PD.

Computer-Aided Screening of Autism Spectrum Disorder: Eye-Tracking Study Using Data Visualization and Deep Learning (Preprint)
Authors: Cilia Federica , Carette Romuald , Elbattah Mahmoud , Dequen Gilles , Guérin Jean-Luc , Bosche Jérôme , Vandromme Luc , Le Driant Barbara
Published: October 2021

BACKGROUND

The early diagnosis of autism spectrum disorder (ASD) is highly desirable but remains a challenging task, which requires a set of cognitive tests and hours of clinical examinations. In addition, variations of such symptoms exist, which can make the identification of ASD even more difficult. Although diagnosis tests are largely developed by experts, they are still subject to human bias. In this respect, computer-assisted technologies can play a key role in supporting the screening process.

OBJECTIVE

This paper follows on the path of using eye tracking as an integrated part of screening assessment in ASD based on the characteristic elements of the eye gaze. This study adds to the mounting efforts in using eye tracking technology to support the process of ASD screening

METHODS

The proposed approach basically aims to integrate eye tracking with visualization and machine learning. A group of 59 school-aged participants took part in the study. The participants were invited to watch a set of age-appropriate photographs and videos related to social cognition. Initially, eye-tracking scanpaths were transformed into a visual representation as a set of images. Subsequently, a convolutional neural network was trained to perform the image classification task.

RESULTS

The experimental results demonstrated that the visual representation could simplify the diagnostic task and also attained high accuracy. Specifically, the convolutional neural network model could achieve a promising classification accuracy. This largely suggests that visualizations could successfully encode the information of gaze motion and its underlying dynamics. Further, we explored possible correlations between the autism severity and the dynamics of eye movement based on the maximal information coefficient. The findings primarily show that the combination of eye tracking, visualization, and machine learning have strong potential in developing an objective tool to assist in the screening of ASD.

CONCLUSIONS

Broadly speaking, the approach we propose could be transferable to screening for other disorders, particularly neurodevelopmental disorders.
How Food Marketing on Instagram Shapes Adolescents’ Food Preferences: Online Randomized Trial (Preprint)
Authors: Bragg Marie , Lutfeali Samina , Greene Tenay , Osterman Jessica , Dalton Madeline
Published: October 2021

BACKGROUND

Worldwide obesity rates have prompted 16 countries to enact policies to reduce children’s exposure to unhealthy food marketing, but few policies address online advertising practices or protect adolescents from being targeted. Given adolescents spend so much time online, it is critical to understand how persuasive Instagram food advertisements (ads) are compared with traditional food ads. To strengthen online food marketing policies, more evidence is needed on whether social media ads are more persuasive than other types of ads in shaping adolescents’ preferences.

OBJECTIVE

This study examined whether adolescents could identify food companies’ Instagram posts as ads, and the extent to which Instagram versus traditional food ads shape adolescents’ preferences.

METHODS

In Part 1, participants aged 13-17 years (N=832) viewed 8 pairs of ads and were asked to identify which ads originated from Instagram. One ad in each pair was selected from traditional sources (eg, print; online banner ad), and the other ad was selected from Instagram, but we removed the Instagram frame—which includes the logo, comments, and “likes.” In Part 2, participants were randomized to rate food ads that ostensibly originated from (1) Instagram (ie, we photoshopped the Instagram frame onto ads); or (2) traditional sources. Unbeknownst to participants, half of the ads in their condition originated from Instagram and half originated from traditional sources.

RESULTS

In Part 1, adolescents performed worse than chance when asked to identify Instagram ads (P<.001). In Part 2, there were no differences on 4 of 5 outcomes in the “labeled ad condition.” In the “unlabeled ad condition,” however, they preferred Instagram ads to traditional ads on 3 of 5 outcomes (ie, trendiness, P=.001; artistic appeal, P=.001; likeability, P=.001).

CONCLUSIONS

Adolescents incorrectly identified traditional ads as Instagram posts, suggesting the artistic appearance of social media ads may not be perceived as marketing. Further, the mere presence of Instagram features caused adolescents to rate food ads more positively than ads without Instagram features.

BACKGROUND

The COVID-19 pandemic has necessitated the adoption and implementation of digital technologies to help transform the educational ecosystem and the delivery of care.

OBJECTIVE

We sought to understand instructors’ and learners’ perceptions of the challenges and opportunities faced in implementing health information system virtual training amid the COVID-19 pandemic.

METHODS

Semistructured interviews were conducted with education specialists and health care staff who provided or had taken part in a virtual instructor-led training at a large Canadian academic health sciences center. Guided by the Technology Acceptance Model and the Community of Inquiry framework, we analyzed interview transcript themes deductively and inductively.

RESULTS

Of the 18 individuals participating in the study, 9 were education specialists, 5 were learners, 3 were program coordinators, and 1 was a senior manager at the Centre for Learning, Innovation, and Simulation. We found 3 predominant themes: adopting a learner-centered approach for a meaningful learning experience, embracing the advances in educational technologies to maximize the transfer of learning, and enhancing the virtual user experience.

CONCLUSIONS

This study adds to the literature on designing and implementing virtual training in health care organizations by highlighting the importance of recognizing learners’ needs and maximizing the transfer of learning. Findings from this study can be used to help inform the design and development of training strategies to support learners across an organization during the current climate and to ensure changes are sustainable.

La “Plaza de la Dignidad” como escenario de protesta. La dimensión cultural en la comprensión del acontecimiento de Octubre chileno
Authors: Paredes P. Juan Pablo
Published: October 2021

How did cultural factors participate in the event of October in Chile? How were these factors related to each other? What implications did they have for collective action and social life? The purpose of the article is to carry out a cultural reading of the October event. To do this, a dialogue is proposed between cultural sociology and cultural studies, applied to the October protest movement, resorting to interpretive research tools. The appropriation of Plaza Italia, in Santiago, by the protesters, is used in an illustrative way to highlight the cultural elements and their interactions. Among the findings, the production of meaning based on motifs and frames stands out, the production of its own symbolism and iconography and the deployment of performances that allow defining the Plaza itself as an artifact of protest. Then certain scopes of the above for civil society are discussed. It concludes with a projection of the work and a brief reflection on the relationship between social sciences and humanities to deploy an interpretive strategy of empirical research.

Published: October 2021

As part of the 113th cruise of the R/V “Professor Vodyanitsky”, research was conducted on organic pollution of bottom sediments in the coastal areas of Crimea and the Caucasus, as well as the water area in front of the Kerch Strait. Concentration of chloroformextractable substances was determined by the weight method and that of petroleum hydrocarbons was determined using infrared spectrometry. Both in 2020 and 2016 (the 83d cruise of the R/V “Professor Vodyanitsky”), properties of the bottom sediments of the Crimean and Caucasian coasts were typical of the marine soils of this region. This indicates that the studied water areas are generally in good condition. In accordance with the regional classification of bottom sediment pollution, the maximum concentrations of chloroform-extractable substances obtained for both the Black Sea and the Sea of Azov coast indicate pollution level III (23% of analysed samples). These values were found in bottom sediments in the Sevastopol water area (225 mg·100 g-1), in the coastal area of Cape Tarkhankut (120 mg·100 g-1) and Karadag (120 mg·100 g-1), the southern part of the Sea of Azov (125 mg·100 g-1) and Tuapse (110 mg·100 g-1). The content of chloroform-extractable substances in bottom sediments off the Black Sea coast of the Caucasus and the Sea of Azov coast is slightly lower than that off the Crimean coast. Pollution level II is assigned to bottom sediments in 46 % of the samples, with an average concentration of 72 mg·100 g-1 of air-dry solids. The rest (31 %) of the studied area was classified as conditionally clean (pollution level I, i. e. less than 50 mg·100 g-1). There has been a slight increase in the concentration of petroleum hydrocarbons in the bottom sediments of both the Black Sea and the Sea of Azov and their share in the total amount of chloroformextractable substances. In general, the level of pollution of bottom sediments by organic matter remained unchanged if compared with previous years, in particular with the data from 2016

Published: October 2021

Employees represent the essential assets of any organization. The best organizations oversee human capital in the most efficient and effective way (Nethmini & Ismail, 2019). Blau (2017) highlighted the relevance between human resources management (HRM) practices and the employees’ success at work through enhanced inspiration and commitment. Hence, employee commitment cannot be overlooked as the degree of employee commitment can decide employee performance (Ahmad, 2014). This paper aims to explore the significance of employee commitment as a mediator in the relationship between HRM practices and employee performance. The target population is employees in the construction industry in Jordan. The respondents were selected utilizing a simple random sampling method. The data was gathered through a self-administered questionnaire and analyzed utilizing structural equation modeling (SEM) in IBM SPSS AMOS 24.0. The researcher obtained an aggregate of 297 usable and completed questionnaires. The study found that: 1) HRM practices have significant effects on employee performance, 2) employee commitment has significant effects on employee performance, 3) HRM practices have significant effects on employee commitment, and more importantly, and 4) employee commitment partially mediates the relationship between HRM practices and employee performance. The implications of the study are also examined

Authors: Ratnasari Desy Putri
Published: October 2021

Informed consent is the consent given to a patient for a medical action after obtaining all important information about the nature and consequences of the action. Procedures regarding the method and content of informed consent still need to be analyzed to provide protection for doctors, patients and related institutions. The purpose of this study is to discuss more deeply about the method and content of informed consent in homeopathic services by practitioners of the Ahmadiyya congregation. This study used a qualitative descriptive method with a total of 20 participants consisting of homeopaths, patients, and staff of the National Homeopathy Department which was conducted through in- depth interviews using purposive sampling and then data is processed using coding and presented descriptively. Homeopaths more often use informed consent oral. The elements of informed consent: • A good way of delivering information is conditioned according to the background and psychological condition of the patient. • Correct in the delivery of homeopathy (how to reveal the patient's diagnosis, alternative goals of action, risks, prognosis where every homeopath never promises a cure to the patient and completely free financing except for homeopaths that have independent clinics. • Complete information the factors that influence the use of homeopathy are dissatisfaction in 34% of patients; need for personal control in 16% of patients; and philosophical congruence in 50% of patients. The application of informed consent is not just giving a signature, but the essence of informed consent is explanation of the information followed by informed consent either in oral or written form so that the patient can make decisions and can be accounted for. More comprehensive education, policies and in-depth socialization of informed consent are urgently needed for practitioners.

Published: October 2021

This article aims to analyze the victim of the offense of rape of a vulnerable person from the perspective of his re victimization through the criminal prosecution process, since he is victimized for the first time through the criminal act and becomes victimized again in the course of the course of the process, since it often results in the innocence of the accused, when he was, in fact, actually guilty. Or, someone who has been victimized many times ends up becoming a victimizer, using the fact of having been the target of a crime to act on other individuals, abusing them. Therefore, through the inductive method, he seeks other means of seeking the unfolding of facts, in order to bring maximum effectiveness and veracity to the judicial system, avoiding errors and false convictions.

Intellectual Property (IP) cores are developed and used to accelerate the custom integrated circuits design flow and improve their final characteristics. There are two types of FPGA IP-cores: hard IP-core and soft IP-core. Hard IP-cores have an exact location and pre-routed in-terconnects while soft IP-cores can be synthesized from logic elements and should be placed and routed. To use IP-cores in automated design flow of integrated circuits on FPGA and RSoC it is necessary to develop IP-core libraries that allow identifying blocks on every stage of flow. This work shows the various soft and hard IP-core libraries’ types and formats used as a part of design flow for Russian FPGA and RSoC. It describes the methods of designing libraries needed by CAD systems at the stages of logic synthesis, automatic technological mapping and layout synthesis. Also, it considers soft and hard IP-core libraries’ distinct features and the methods of their formation adjusted for the FPGA and RSoC architecture. The design methods have been proposed that allow designing of libraries necessary for automated implementation of hard as well as soft IP-cores using advantage of base FPGA and RSoC architecture.

The distribution and abundance of Boloria selene (small pearl-bordered fritillary butterfly, SPBF) declined over recent decades in many parts of the UK. Availability of food plants, especially marsh violet (Viola palustris), for the caterpillars of the SPBF has been identified as one of the major causes of this decline. To achieve augmentation of existing colonies and develop new populations of SPBF large numbers of marsh violet propagules were required specifically to feed the larvae. The main objectives of the study were to produce thousands of good quality marsh violet propagules to restore selected habitats in the Heart of Durham, Northern England, using in vitro methods. Preliminary trials showed that in vitro multiplication of seedlings from wild collected seeds through conventional agar-based cultures was lengthy, expensive and turned out to be a non-viable route to achieve the objectives. This study explored the potential of bioreactor-based cloning and cost-effective one step rooting and weaning. Robust propagules, ready for transplantation following rapid propagation and one step rooting and weaning in vitro, were raised in a plug system for transplantation and establishment under field conditions. This was achieved by using simple and cost-effective methods to support the large-scale restoration exercise using 14,000 propagules. Application of high throughput micropropagation and low cost one step weaning systems for time-bound conservation and restoration projects are discussed in detail. This research highlights the important role of in vitro methods to support integrated biodiversity conservation of a native larval host plant and threatened butterfly.

Science, Technology, Engineering, Mathematics, abbreviated as STEM, is a promising field with increasing popularity due to its benefits in the modern world of globalization and modernization. Science and mathematics are the basics of the technological developments going on in the world. Thus, the children should be motivated to learn STEM from early school days. The minds of small kids are like a sponge, and they can grasp everything quickly. STEM education should be encouraged from childhood so that children like it and continue with it for higher education. This chapter discusses some of the challenges observed while encouraging children to learn STEM early and lists solutions.
Non-Mainstream Realism: An Attempt at Cartography

The article is devoted to the New (non-mainstгeam) гealism. The authoг tries to solve the ргоЬ!еm of the disunity that exists within this movement. The disconnection is that the works of ). Benoist and М. Gabriel оr L. Ваkег and М. Feпaris are consideгed as not connected bу one progгam idea. The solu­ tion to this disconnection is offered through theoretical reconstгuction of the approaches of the men­ tioned authors, which гeveals the oгigins of the philosophical program, the main theses, the categorical apparatus. The conclusions dгawn show that all the pгojects discussed in the article develop as а critical response to the estaЬlished language of philosophy.

Objective: To investigate the efficacy of esomeprazole in managing early preeclampsia. Methods: This randomized controlled trial was conducted at the Obstetric/Gynecology department of Suez Canal University Hospital. We included 160 women between 26-31 years of age, with a singleton pregnancy. Eighty women received esomeprazole along with expectant treatment, whereas 80 women received expectant treatment alone. They were followed up from the date of diagnosis up to four weeks after delivery. The gestational age at termination as well as any complications during the follow-up period were documented and compared between both groups. Results: The mean age of the participants was 30.64 ± 1.62. The gestation of women in the intervention group was longer than those within the control group, with a gestational age at termination of 34.53 ± 1.21 versus 32.78 ± 1.60, respectively (P<0.001). Moreover, women in the intervention group had significantly lower incidences of fits (P= 0.005), antepartum hemorrhage (P=0.005), DIC (P=0.032), and IUFD (P<0.001). Conclusions: Esomeprazole is associated with a significant prolongation of gestation in women with early preeclampsia.

La anestesia espinal es una herramienta fundamental en la práctica anestesiológica. La anestesia raquídea o espinal (AR/AE), también conocida como anestesia intradural o intratecal (AI), está asociada al procedimiento médico mediante el cual se requiere una punción en la membrana dura que recubre la médula espinal y, en la columna vertebral inferior, la raíz de los nervios lumbares y sacros (punción lumbar); de la que se extrae una muestra de líquido cefalorraquídeo del canal medular. El uso de la anestesia raquídea puede generar algunas complicaciones o efectos secundarios, los cuales, a pesar de presentarse con poca frecuencia, la gravedad de alguno de estos, lo convierte en un tema de estudio importante para profesionales de la salud y pacientes. En consecuencia, el objetivo del presente estudio consiste en plasmar las complicaciones en anestesia raquídea. Mediante una metodología de revisión, se aportarán: nociones actuales sobre anestesia raquídea, con énfasis en los efectos secundarios o complicaciones. Las principales complicaciones en la anestesia raquídea son: punción hemática, parestesias, náuseas y vómitos, retención urinaria, lumbalgia y cefalea post-punción. Las complicaciones neurológicas en anestesia raquídea son de las más temidas por médicos, pacientes y familiares, entre ellas el daño neurológico y complicaciones cardiovasculares tales como hipotensión, bradicardia o paro cardiaco. Una complicación asociada con la aplicación de los anestésicos en el canal medular es el síndrome neurológico transitorio (SNT), el cual se manifiesta clínicamente por dolor glúteo que se irradia a miembros inferiores. El conocimiento de estas complicaciones o efectos adversos, de sus causas, su prevención y su tratamiento, es imperioso para disminuir, aún más, su incidencia. Asimismo, es importante su estudio para que, en casos de presentarse, la gravedad de sus consecuencias se mínima y evitar daños irreversibles como lo son los daños neurológicos.
