Ion-exchange membranes for blue energy generation: A short overview focused on nanocomposite
Authors: Hong Jin Gi , Park Tae-Won
Published: August 2022

Blue energy can be harvested from salinity gradients between saline water and freshwater by reverse electrodialysis (RED). RED as a conversion technique to generate blue energy has received increasing attention in recent decades. As part of the RED system, ion exchange membranes (IEMs) are key elements to the success of future blue energy generation. However, its suboptimal performance often limits the applications and stagnates the deve­lopment of the technology. The key properties of IEMs include ion exchange capacity, perm­selectivity, and electrical resistance. The enhancement of such physical and electrochemical properties is crucial for studying energy production with acceptable output efficiency on a commercial scale. Recently, many studies have tried blending nanotechnology into the membrane fabrication process. Hybridizing inorganic nanomaterials with an organic polymeric material showed the great potential of improving electrical conductivity and perm­selectivity, as well as other membrane characteristics for power performance. In this short review, recent developments on the IEM synthesis in association with potential nanomaterials are reviewed and raising issues regarding the application and commercialization of RED-based energy production are discussed.
Body composition in pancreatic cancer patients
Authors: Kowalska Magdalena , Kamocki Zbigniew
Published: August 2022

Pancreatic cancer, despite significant progress in diagnosis and treatment, still has poor prognosis. Surgical treatment remains the only curative option. Unfortunately, radical tumor resection is possible in less than 20% of patients. Surgical resection may be difficult, and can be associated with a high complication rate. One of the important factors contributing to the high morbidity in the perioperative period is malnutrition, together with rapidly progressing malnutrition which affects about 85% of pancreatic cancer patients. Abnormal nutritional status is closely related to changes in the body's composition. The aim of the study was to determine the changes in the body composition in pancreatic cancer patients and their consequences based on the results of the current research. The available reports have shown that the body composition in pancreatic cancer patients changes undoubtedly and depends on staging, location and type of cancer. Furthermore, whether anticancer therapy is initiated or not can also play a significant role. It appears that in patients with pancreatic cancer, weight loss with a decline in parameters such as body fat and skeletal muscle mass occurs early and worsens as the tumor grows and the disease progresses. The above data suggest that knowing the patient's body composition and observing its changes may be a prognostic factor for survival and complications. Additionally, there have been reports that chemotherapy dosing based on body composition rather than conventional measurements can help reduce toxicity of treatment. Therefore, knowing the patient's body composition seems to be important.
Spilled gallstones after laparoscopic cholecystectomy: a systematic review
Authors: Salati Sajad Ahmad , Alfehaid Mohammed , Alsuwaydani Saleh , AlSulaim Lamees
Published: August 2022

 Aim:  The study was conducted to analyse the recent peer-reviewed literature related to symptomatic spilled gallstones after Laparoscopic Cholecystectomy (LC).

 Materials and methods: Articles published in the peer-reviewed journals of repute from 2012–2022 were evaluated for nine variables including: [I] age of the patient, [II] gender, [III] interval since index LC, [IV] index LC if emergent/difficult or elective/straightforward, [V] clinical presentation, [VI] spilled gallstones if detected by imaging, [VII] management, [VIII] approach to management, [IX] number of spilled gallstones.

 Results: There were a total of 71 cases (37 males and 34 females) with a mean age of 63.7 years. The time of onset of symptoms from spilled gallstones, after index LC, ranged from 2 days to 15 years and 57 patients (80.3%) presented within 6 years. Forty (56.3%) patients were unaware of the fact that gallstone spillage had occurred during index LC. The retained gallstones were detected by imaging in 47 (66.1%) cases and they were multiple in 51 (71.8%). In 52 patients (73.2%), the stones manifested as abdominal abscess/foreign body granuloma; the other presentations being pelvic pain/fistula, intestinal obstruction, abdominal lump simulating malignancy, incidental finding of metastatic lesions and generalized peritonitis. The major approaches adopted to retrieve the retained stones included open surgery, laparoscopy and percutaneous drainage. There were two deaths (2.9%) due to spilled gallstones.

 Conclusion: Retained gallstones represent a complication of laparoscopic cholecystectomy (LC) that has a potential to create morbidity and diagnostic difficulties, even after a substantial delay. There is a need to spread awareness about the adverse effects of spilled stones so that they are actively looked for and retrieved if gallbladder perforates during cholecystectomy. Whenever such a complication occurs, the patient should be properly informed and the details should be very clearly mentioned in the operation notes.

Fractional Carbon Dioxide Laser Therapy Compared to Ospemifene in the Treatment of Vaginal Atrophy in Menopause.
Authors: Somtochi Miracle Udekwe
Published: August 2022

During the menopausal transition, women often experience an array of symptoms, including vaginal dryness, itching, pain, burning, decreased sexual desire, and inadequate lubrication, which are all due to hormonal changes called hypoestrogenism. Hypoestrogenism simply means a low level of estrogen which turn leads to a constellation of symptoms including hot flashes, urinary tract infections, decreased bone density and sleep disturbances. Some women find these symptoms embarrassing not to seek help, while some take it as a natural process of aging. Although various researchers have established different treatments in the past, such as lubricants and moisturizers, newer therapies such as fractional carbon dioxide (CO2) laser therapy and a selective estrogen receptor modulator ospemifene are currently being used and yet still researched. To highlight the lack of research on this topic, our article search involving only the PubMed database yielded 175 articles initially, but after exclusion and inclusion criteria, we were left with only 32 studies directly related to our research topic. Our study included English articles, full-text articles, articles on human studies, and articles from 2005- 2020. We excluded all studies prior to 2005, animal studies, pediatrics study, and only abstract study. All articles were chosen without limitation to the type of study. Our review suggests that patients often present with various symptoms and severity based on histology, mechanisms, and clinical findings. Therefore, treatment should be personalized. Our study aimed to further understand a better treatment option for vulvovaginal atrophy (VVA) in postmenopausal women, knowing that menopause is an inevitable stage of a woman's life.
Brics as a Dynamic and in Process Phenomenon of Global Planning: An Analysis Based on the 2009-2020 Annual Summit Declarations
Authors: Daldegan William , Carvalho Carlos Eduardo
Published: August 2022

Brazil, Russia, India, China, and South Africa are very heterogeneous countries and the BRICS is a very original arrangement. This paper asserts that the BRICS is a dynamic and in process phenomenon: dynamic because it is developed according to the member’s perceptions about world scenario, without establishing limitations on strategies and initiatives of each member country; in process because it is developed through specific processes, in which members do not point any destination or institutionalization to be achieved. At the annual summit meetings held regularly since 2009, the BRICS issues a Declaration. The most prominent topics on the international framework are punctuated and criticized, with generic proposals to handle or to solve them. The declarations do not show any progressive stages on approaching these topics, neither consolidation of commitments among the members on them. Such documents represent the main primary source for the characterization of the group and its behavior. The innovation of this paper is to deepen the use of primary sources to move forward in the effort for the BRICS conceptualization and to analyze its performance throughout the years. The documentary analysis of Summit Declarations is developed by using two text analysis software packages, AntConc and VOSviewer.
Information-Theoretic Analysis of EEG Signals to Differentiate Schizophrenic Patients with Positive and Negative Symptoms and Control Group
Authors: Afrooz Erfan , Taghavi Mahsa
Published: August 2022

Background: The precise differentiation of schizophrenic patients with positive and negative symptoms is still challenging; hence, psychiatrists mainly focus on diagnosing schizophrenic patients with positive symptoms. However, schizophrenic patients with negative symptoms have revealed remarkably poor outcomes. Objectives: This study aimed to differentiate schizophrenic patients with positive and negative dominant symptoms quantitatively by classifying their electroencephalography (EEG) features. Methods: In this study, 36 patients with schizophrenia and 26 age-matched control subjects voluntarily participated. Their EEG signals were captured and characterized by elicited multiscale entropy to decode the amount of irregularities occurred in each EEG channel. The principal component analysis (PCA) was deployed to decrease the dimension of elicited features, and the reduced features were applied to three Gaussian Naïve Bayes classifiers, each of which was trained for a specific class. Results: The classification of the three groups resulted in 77.86% accuracy, while this accuracy in the schizophrenic groups provided 65% accuracy. In the resting state, the normal and schizophrenic subjects were differentiated by a high rate (95.43%). Conclusions: Exploiting information-theoretic features of the EEG signals over the scalp and automatic classification of these features, we can well-differentiate schizophrenic patients with different dominant symptoms. Moreover, better classification results can be achieved by passing the EEG features through PCA.
Základní školy v procesu adaptace na výuku na dálku : vícepřípadová studie
Authors: Šalamounová Zuzana
Published: August 2022

Předložená vícepřípadová studie se věnuje problematice adaptace základních škol na distanční výuku v období jejich prvního uzavření v průběhu jara roku 2020 v důsledku pandemie covid-19. Záměrem studie je přiblížit, co se od 11. března 2020 odehrávalo za dveřmi uzavřených škol. Data, z nichž tato studie vychází, byla sesbírána na pěti základních školách. Z výsledků analýzy vyplývá, že zásadním bodem celého procesu adaptace bylo rozhodnutí vedení školy, zda ve škole dojde k tzv. centralizaci, tzn. celá škola bude nadále výuku a další procesy související s výukou koncipovat jednotně, nebo zda škola půjde cestou autonomie učitelů, kteří budou realizovat výuku dle vlastního plánu jakožto odborníci na svůj předmět a svou třídu. Data dále napovídají, že pokud se vedení školy rozhodlo pro centralizaci a poskytlo učitelům potřebnou podporu pro naplnění nastavených požadavků, došlo tím k distribuci zodpovědnosti – vedení převzalo zodpovědnost za technické, organizační a koncepční nastavení výuky na dálku, zatímco učitelé se mohli se soustředit na rozvoj digitálních kompetencí a nezbytné úpravy kurikula vyplývající z přechodu na výuku na dálku. V rámci školy jako celku pak postupně došlo ke stabilizaci výuky na dálku. U škol, které se vydaly cestou autonomie učitelů, lze oproti tomu stabilizaci výuky na dálku sledovat u jednotlivých učitelů, avšak nikoli jednotně v rámci školy jako organizace.

Published: August 2022

Smoking is one of the biggest causes of death in the world. The WHO reported that smoking kills 8 million people each year. Besides threatening global health, smoking by rural people tends to detain poverty alleviation efforts due to several factors, including cigarette expenditures and health expenditures. Indonesia has one of the most significant worldwide smoking prevalence and has become one of the countries that most suffer from smoking. The MoH Indonesia reported that health costs due to smoking reached Rp596.61 trillion in 2015. Previous studies found that smoking caused an increase in health expenditure due to smoking-related diseases in Indonesia. However, there is a lack of evidence found in rural areas. This research aims to answer whether smoking affects health expenditure in rural areas. Robust regression analysis is used in this model and processed by STATA 14 application. Using IFLS 5 data, the analysis shows that cigarettes consumed in rural areas have a positive and significant effect on outpatient costs. Increased outpatient costs in rural areas due to smoking will make the rural economy suffer and escalate poverty. The government should intensify the tobacco control policy in rural areas to avoid an increase of poverty rate in Indonesia.

Authors: Alvaro Rendy , Christianingrum Ratna , Riyono Tio
Published: August 2022

Maternal Mortality Rate (MMR) and Infant Mortality Rate (IMR) are essential indicators of health development that are written on the national development plan documents. Nevertheless, Indonesia has not yet achieved the national target of MDG’s and SDG’s. In prediction, without extraordinary policies, the target of SDGs will not be reached by 2030. The government has allocated DAK Fisik Penugasan as one of the efforts to reduce MMR and IMR. So this study aims to capture the effect of DAK Fisik in decreasing MMR and IMR. Panel data from 34 provinces level in 2019 and 2020 are analyzed using mean difference test and quadrant analysis. Results show that there is no significant difference of MMR in 34 provinces with or without DAK Fisik Penugasan. Then there are still many provinces with the lower MMR and IMR which get budget priorities and vice versa. The government should 1) provide a local government stimulus to enhance acceleration of reducing MMR and IMR; 2) allocate budget priority to provinces that have higher score of MMR and IMR; 3) Encourage local governments to improve the quality of DAK Fisik proposals along with better quality of budget absorption.

In order to verify that the large-scale low-density plasma has a significant gain effect on the quality of the ultra-hot electron beam in ultra-strong ultra-short pulse laser interactions with matter, on the Shenguang-II upgraded laser facility, we carry out an experimental study on the optimization of relativistic electron beams that combine long and short pulse lasers to generate large-scale low-density pre-plasma. A nanosecond laser is used to ablate the thin hydrocarbon film. After a period of time, a large-scale low-density plasma is formed. The second picosecond short pulse laser then interacts with the formed low-density plasma, and accelerates the electrons to the relativity magnitude. Through the comparative analysis between different experimental conditions in the experiment, it is found that the existence of large-scale low-density plasma significantly increases the intensity of the relativistic electron beam along the laser propagation direction. In the comparative test of three shooting methods (long and short pulse combined driving double-layer target, short pulse driving double-layer target, short pulse driving single-layer target), we find that the energy bands above 1 MeV can be produced by the long pulse and the short pulse jointly driving double-layer target. The gamma-ray intensity is nearly twice that of the other two schemes. In addition, we also find in the experiment that when the time interval between nanosecond-picosecond pulses changes, the pre-plasma electron density and density scale length of the CH film irradiated by the nanosecond laser will be different. When the time interval is 0 ns, the expansion of the plasma is still insufficient, and the density distribution of the pre-plasma is steep. Part of the picosecond laser energy will be reflected at the critical density surface. Insufficient absorption of picosecond laser energy reduces the generation of relativistic electrons.When the time interval is 1 ns, the plasma state is more appropriate. The picosecond laser will form a self-focusing plasma channel in the plasma, thereby efficiently depositing energy, breaking through the energy limit of ponderomotive force acceleration, and obtaining more higher energy relativistic electrons. When the time interval is longer, such as 1.5 ns or more, the plasma can be fully expanded, the electron density becoming too low. Most of the picosecond laser will pass through the pre-plasma, affecting energy deposition and failing to generate more relativistic electrons.

By using the finite temperature field theory, the one-loop effective potential and the dynamics of the quantum chromodynamics deconfinement phase transition in the framework of Friedberg-Lee model are studied at finite temperature and density. Our results show that there is a first-order deconfinement phase transition for the full phase diagram, and the critical temperature is about 119.8 MeV for a zero chemical potential whereas the critical chemical is around 256.4 MeV when the temperature is fixed at T = 50 MeV. Moreover, in the thin-wall approximation, we investigate the dynamics of a strong first-order quark-hadron transition via homogeneous bubble nucleation in the Friedberg-Lee model. Under an appropriate boundary condition, the equation of motion for the \begin{document}$ \sigma $\end{document} field is solved, then the evolutions of the bubble critical configuration with radius \begin{document}$ r $\end{document} at different temperatures and densities are calculated. The surface tension, the typical radius of the critical bubble and the shift in the coarse-grained free energy each as a function of temperature and chemical potential are obtained. In order to gain the reliability and advantages of the thin-wall approximation, our analytical results based on the thin-wall approximation are compared with those obtained by the exact numerical method accordingly. Finally, some consequences and possible applications of our results in the quark meson model and Polyakov quark meson model are also presented in the end of this paper.

Two-dimensional topological insulator (2DTI) with a large bandgap is prerequisite for potentially observing quantum spin Hall and other quantum phenomena at room-temperature. At present, the synthesis of such materials possesses formidable challenge. In this work, we report our experimental results on synthesis of large-gap 2DTI stanene and bismuthene on B-faced InSb(111) substrate by using molecular beam epitaxy technology. We find that both the stanene and bismuthene can be synthesized by following the forming of a wetting layer on InSb(111) substrate, but with different prospects. On the one hand, it is found that the binding energy between Sn and the substrate is not strong enough to compete the binding force between Sn atoms during the post annealing, thus resulting in a wetting layer composed of many small domains. It significantly restricts the quality of the stanene epilayers. On the other hand, the Bi atoms on InSb(111) are found more stable than the Sn atoms on InSb(111), resulting in a uniform wetting layer which can be optimized by adjusting substrate temperature and post-annealing conditions. Large size and single crystal bismuthene domains have been observed under the STM measurement, which also indicates a bulk gap of ～0.15 eV and metallic edge states.

In this work, composite ceramics (1–x)Pb0.99Nb0.02[(Zr0.57Sn0.43)0.94Ti0.06]0.98O3:xAlN (abbreviated (1–x)PNZST:xAlN, x = 0, 0.1, 0.2, 0.3 and 0.4) are prepared by a two-step solid phase synthesis method. The crystal structures, micromorphologies, domain structure evolutions, ferroelectric, dielectric and pyroelectric properties of those composite ceramics are systematically investigated. The results show that the difference in thermal expansion coefficient between PNZST and AlN creates compressive stresses in the PNZST matrix when cooling down from the sintering temperature, then a metastable ferroelectric (FE) phase is induced in the anti-FE matrix by the AlN component-induced internal stress, and in turn ferroelectric/antiferroelectric phase boundary is constructed near room temperature. As the temperature increases, the ferroelectric-to-antiferroelectric phase transition causes a larger pyroelectric current peak. In particular, the composition with x = 0.1 exhibits a high pyroelectric coefficient p = 3.3×10–3 C⋅m–2⋅K–1 and figure-of-merit with current responsivity Fi = 3.16×10–9 m⋅V–1, voltage responsivity Fv = 0.613 m2⋅C–1, and detectivity Fd = 4.4×10–4 Pa–1/2 around human body temperature. Moreover, the enhanced pyroelectric coefficient exists in a broad operation temperature range with a large full width at half maximums of 16.3 ℃ at 37 ℃. With the increase of AlN content, the pyroelectric peak temperature of the composite ceramic is adjustable in a wide temperature range of 37–73 ℃, showing good temperature stability.

Flow analysis and low-dimensional representation model is of great significance in studying the complex flow mechanism. However, the turbulent flow field has complex and unstable spatiotemporal evolution feature, and it is difficult to establish the low-dimensional representation model for the flow big data. A low-dimensional representation model of complex flow is proposed and verified based on the flow time-history deep learning method. One-dimensional linear convolution, nonlinear full connection and nonlinear convolution autoencoding methods are established to reduce the dimension of unsteady flow time history data. The decoding mapping from low-dimensional space to time domain is obtained to build the representation model for turbulence. The proposed method is verified by using flow around the square clyinder with Re = 2.2×104. The results show that the flow time-history deep learning method can be used to effectively realize the low-dimensional representation of the flow and is suitable for solving the complex turbulent flow problems; the nonlinear one-dimensional convolutional autoencoder is superior to the full connection and linear convolution methods in representing the complex flow features. The method in this work is an unsupervised training method, which can be widely used in single-point-based sensor data processing, and is a new method to study the characteristics of turbulence and complex flow problems.
Effect of PMT output electron flow pulse pile-up on photon counting ranging method
Authors: Yuyan Xiang  , Li song  , Ma yue  ,   School of Electronic Information, Wuhan University, Wuhan 430072, China
Published: August 2022

Photomultiplier tubes (PMT) have single photon level sensitivity, low dark count, low after pulse probability, and are widely used in photon-counting lidar in visible spectrum. PMT has no photon detection dead time, for every photon it responds to, it sends out a electron flow pulse, these pulses of electron flow have the po·tential to pile up into larger pulses. When using threshold identification method to identify photon-events, stacked pulse will introduce additional pulse walking error, in the practical application of laser ranging, will directly affect the ranging precision of photon-counting ranging method. Considering the influence of pulse pile-up, a new theoretical model of PMT photon detection was established to describe the influence of pulse pile-up on the detection probability of photon-events by analyzing the relationship between the detection time of photon and the identification time of the PMT final output photon-events. Through Monte Carlo simulation, the relationship among the ranging walking error, ranging accuracy, incident laser pulse width, PMT output electron flow pulse width and photon-events identification threshold is obtained. In order to verify the correctness of the theory, a PMT-based photon-counting lidar system is built. The comparison experiment with GM-APD proves that the influence of pulse pile-up on PMT photon-counting ranging method can not be ignored, and the experimental results are in good agreement with the theoretical model.

This paper reports the adsorptions behavior of the 9,9'-Dixanthylidene on Ru(0001), the bottom-up fabrication of graphene was also investigated through a Scanning Tunneling Microscope (STM). We analyzed the spatial structure of 9,9'-Dixanthylidene molecules which were randomly dispersed on the Ru(0001) substrate in the sub-monolayer coverage. Then we bottom-up fabricated the graphene on Ru(0001) substrate with the 9,9'-Dixanthylidene molecules as the precursor. Three kinds of moiré superstructures with different rotation angles (6.3°, 13.9°, and 16.1°) were found after high temperature annealing in an ultrahigh vacuum. This experiment provides data support for the study of moiré superstructures on Ru(0001) substrate and lays a solid foundation for further scientific research based on graphene/Ru(0001).

Uses and gratifications theory helps in studying the underlying needs for using media that lead to positive behavioral intention and satisfaction. One of its approaches is gratification discrepancies (i.e., the difference between gratifications obtained and gratifications sought [GO-GS]) helps to explore the gratifications of using media and the results obtained after using media. The GO-GS approach provides an opportunity to collect the data two times, both before and after the usage of media. Several researchers have suggested this approach as a suitable method for investigating attitudinal change, beliefs, satisfaction, and behavioral intentions. Despite the importance of the GO-GS approach, there is a lack of systematic literature review to summarize the developments in academic literature related to GO-GS. Therefore, this review addresses this gap by assessing the articles using the GO-GS approach published from 1979–2020. A research string was developed using Boolean operators to search the literature. A total of 4,184 articles were considered for the initial screening, but only 23 articles met the inclusion criteria. These articles were critically analyzed, and seven main realms are proposed, grounded in developments in the literature, such as research context, regions of research, media, gratifications, consumer behavior, other theories or models, and different conceptualizations to study gratification discrepancies.

The human community all over the world are growing consciousness over poisonous residues of agrochemicals in the food they consume and also on the health and environmental hazards associated with it. This therefore lead to a re-invention of an alternate form of agriculture devoid of contaminants. Organic agriculture is one among the broad spectrums of production systems which avoids the use of synthetic agrochemicals and ensures safety and sustainability. An Ex-post facto research design was used for the study. The study was conducted in Coimbatore and Tirupur districts to study the extent of adoption of farmers towards organic vegetable cultivation. The analysis of the data inferred that two-fifths of the respondents (40.83%) belonged to old aged category. Regarding the belief of farmers in organic farming it was found that nearly half of the respondents (49.17%) had belief only in organic farming and avoided conventional farming methods. It was interesting to note that almost all the respondents (100%) had full adoption towards timely irrigation and mulching practices.
