Authors: Adi Putra Adi Putra , Deka Deka Veronica
Published: August 2021

Protein consumption for the community is very important and must be known, because improving nutritional status is the basis for the formation of quality, healthy, intelligent, productive, and independent human resources in an area. The level of public protein consumption, especially from beef products, is strongly influenced by the conditions of product supply and demand, because these indicators also affect prices and the level of inflation in general. For this reason, research needs to be done specifically to analyze the effect of price, inflation and per capita expenditure on the protein consumption pattern of the people in Jambi Province. The design of this research is a quantitative analysis of time series data for the period 2007-2018 which is further analyzed by Path Analysis. The results showed that there was no direct influence between the variable foodstuff inflation (IBM) and Beef Price (HDS) on Community Per Capita Expenditure (PBM), but PBM had an effect on Community Protein Consumption (KPM). The indirect effect between IBM on KPM through PPM and HDS on KPM through PPM has a significant effect. To maintain a healthy condition for protein consumption in Jambi Province, the government needs to take policies such as maintaining a stable condition of foodstuff inflation and beef prices in the market.

Heat Flow Correction for the High-Permeability Formation: A Case Study for Xiong’an New Area
Authors: Wang Zhuting , Gao Peng , Jiang Guangzheng , Wang Yibo , Hu Shengbiao
Published: August 2021

The Xiong’an New Area is located at the western Bohai Bay Basin, 150 km south of Beijing, China. The area has tremendous high heat flow value within the sedimentary layer, and the average value can reach 90 mW·m-2 within the Niutuozhen Uplift. However, combining the basal heat flow at the top of the metamorphic layer with the heat flow value which was contributed by the radiogenic heat production from the overlying formation, the surface heat flow value was only 65.1 mW·m-2 in this area. Thus, the heat flow value within the sedimentary layer was greatly influenced by other factors. In this study, based on the continuous temperature measurements data from 4 boreholes, thermos-physical parameters (conductivity, radioactive heat production, density, and heat capacity) from 90 rock sample measurements, and the regional stratigraphic development, a two-dimensional thermal-hydraulic modelling was carried out to study the influence of the heat refraction and groundwater convection on the heat flow value. According to calculation results, the heat flow disturbance caused by heat refraction was 10 mW·m-2, and the disturbance value was 20 mW·m-2 for the groundwater convection. Furthermore, when the high-permeability layer thickness was a certain value, with the increasing high-permeability layer buried depth, the influence of the groundwater convection on the temperature field which was used for the heat flow calculation became weak. While when the high-permeability layer buried depth was set up, the influence of the groundwater convection on the above temperature field became stronger with the increasing high-permeability layer thickness.

The article presents the results of identification and quantitative analysis of the phase composition, fine structure parameters of minerals in carbonate and terrigenous rocks by the use of modern X-ray diffraction (XRD) analysis. To make the XRD analysis, we optimized the modes of x-ray pattern shooting by changing the radius of the goniometer, the system of primary and secondary slits, Soller slits, and the system of detecting the low-content minerals. In processing the obtained x-ray patterns, we considered the size and defects of the crystal grains, the crystallographic mode of arrangements, atomic population of the crystal lattice, the Debye-Waller factor and the instrumental line broadening by the use of the Caliotti function for LaB6. So we determined the type and content of minerals, estimated the period of the crystal lattice, the size of the coherent scattering domains and micro-distortion crystal lattice of the mineral. We compared the obtained data on the presence and quantitative content of minerals with the data of X-ray fluorescence (XRF) analysis and scanning electron microscopy (SEM). Based on the obtained data, reference intensity ratio (RIR) coefficients were selected for a number of minerals typically contained in core materials for quantitative phase analysis by the use of the corundum number method.

Authors: Gorrochategui Eva , Hernandez Isabel , Pérez-Gabucio Eva , Lacorte Sílvia , Tauler Romà
Published: August 2021

In this study, changes in air quality by NO2, O3 and PM10 in Barcelona metropolitan area and other parts of Catalonia during the COVID-19 lockdown with respect to pre-lockdown and to previous years (2018 and 2019) were evaluated. Selected air monitoring stations included 3 urban (Gràcia, Vall d’Hebron and Granollers), 1 control site (Fabra Observatory), 1 semi-urban (Manlleu), and 3 rural (Begur, Bellver de Cerdanya, and Juneda). NO2 lockdown levels showed a diminution, which in relative terms was maximum in two rural stations (Bellver de Cerdanya, -63% and Begur, -61%), presumably due to lower emissions from the ceasing hotel and ski resort activities during eastern holidays. In absolute terms and from an epidemiologic perspective, decrease in NO2, also reinforced by the high amount of rainfall registered in April 2020, was more relevant in the urban stations around Barcelona. O3 levels increased in the transited urban stations (Gràcia, +42%, and Granollers, +64%) due to the lower titration effect by NOx. PM10 lockdown levels decreased, mostly in Gràcia, Vall d’Hebron and Granollers (-35, -39% and -39%, respectively) due to traffic depletion (-90% in Barcelona's transport). Correlation among mobility index in Barcelona (-100% in retail & recreation) and contamination was positive for NO2 and PM10 and negative for O3 (P<0.001). Satellite images evidenced two hotspots of NO2 in Spain (Madrid and Barcelona) in April 2018 and 2019 that disappeared in 2020. Overall, the benefits of lockdown on air quality in Catalonia were evidenced with NO2, O3 and PM10 levels below WHOAQG values in most of stations opposed to the excess registered in previous years.

Multi-Scopic Neuro-Cognitive Adaptation for Legged Locomotion Robots
Authors: Saputra Azhar Aulia , Wada Kazuyoshi , Masuda Shiro , Kubota Naoyuki
Published: August 2021

Dynamic locomotion is realized through a simultaneous integration of adaptability and optimality. This article proposes a neuro-cognitive model for multi-legged locomotion robot that can seamlessly integrate multi-modal sensing, ecological perception, and cognition through the coordination of interoceptive and exteroceptive sensory information. Importantly, cognitive models can be discussed as micro-, meso-, and macro-scopic; these concepts correspond to sensing, perception, and cognition; and short-, medium-, and long-term adaptation (in terms of ecological psychology). The proposed neuro-cognitive model integrates these intelligent functions from a multi-scopic point of view. Macroscopic-level presents an attention mechanism with short-term adaptive locomotion control conducted by lower-level sensorimotor coordination-based model. Macrosopic-level serves environmental cognitive map featuring higher-level behavior planning. Mesoscopic level shows integration between the microscopic and macroscopic approaches, enabling the model to reconstruct a map and conduct localization using bottom-up facial environmental information and top-down map information, generating intention towards the ultimate goal at the macroscopic level. The experiments demonstrated that adaptability and optimality of multi-legged locomotion could be achieved using the proposed multi-scale neuro-cognitive model, from short to long-term adaptation, with efficient computational usage. Future research directions can be implemented not only in robotics contexts but also in the context of interdisciplinary studies incorporating cognitive science and ecological psychology.

Published: August 2021

Background: The aim of this study was to analyze the effect of unilateral K-rod dynamic internal fixation on paraspinal muscles for lumbar degenerative diseases. Methods: This study retrospectively collected 52 patients who underwent lumbar surgery with the K-rod group or PLIF. The operation time, intraoperative blood loss, postoperative drainage volume, postoperative exercise time were compared in the two groups. The visual analog scale (VAS) score and the oswestry dysfunction index (ODI) were employed to evaluate the clinical outcomes. The functional cross-sectional area (FCSA) of the paraspinal muscles and paraspinal muscles fat infiltration were measured to assess on the paraspinal muscles. Results: As compared with the PLIF group, the operation time, the postoperative time in the field, and the average postoperative hospital stay in the K-rod internal fixation group were significantly shortened. At the last follow-up, both the groups showed significant improvement in the VAS score and ODI. The FCSA atrophy of the upper and lower adjacent segments (UAS and LAS) of the K-rod internal group was significantly less than that of the PLIF group. The extent of increase in the fatty infiltration of the paraspinal muscles in the K-rod group was significantly lesser than that in the PLIF group. The postoperative low back pain of the two groups of patients was significantly positively correlated with the FCSA atrophy.Conclusions: As compared to PLIF, the posterior lumbar unilateral K-rod dynamic internal fixation showed significantly lesser paraspinal muscle atrophy and fatty infiltration, which were significantly positively correlated with postoperative low back pain.

Authors: Adeleke Adeniyi , Khaled Abou-El-Hossein , Peter Odedeyi
Published: August 2021

The desire for quality infrared lens with better surface finish has brought about the usage of brittle materials like germanium to be machined via a single point diamond turning machining process. However, achieving the required surface finish is complex if special machining techniques and approaches are not employed. In this paper, the effect of two different tool nose radius parameters on surface roughness of single point diamond turned germanium workpiece were studied and analyzed. The machining parameters selected for this experiment were feed, speed and depth of cut. Box-Behnken design was adopted to optimally create a combination of cutting parameters. Measurement of surface roughness after each run in both experiments was achieved using a Taylor Hobson PGI Dimension XL surface Profilometer. The resulting outcomes show that at most experimental runs, the surface roughness value decreased with an increase in nose radius. Mean absolute error was also used to compare the accuracy validation of the two models.

Authors: Tian Jin , Yuan Liang , Xiao Wendong , Ran Teng , Zhang Jianbo , He Li
Published: August 2021

For achieving trajectory tracking issue of the lower limb exoskeleton robot, a novel optimal robust control with cooperative game theory is proposed. The uncertainties are considered (possible time-varying, bounded and fast) and the fuzzy set theory is creatively adopted to describe the boundary. From the view of analytical mechanics, the trajectory tracking is treated as the constraints control problem, including holonomic and nonholonomic constraints. A robust control is designed with two adjustable parameters to guarantee the uniform boundedness and uniform ultimate boundedness. For obtaining the optimal selection of two adjustable parameters, a novel optimal control employed cooperative game theory is proposed. Combining the robust control and optimal design, optimal robust control is formulated. The Pareto optimal solution is obtained to guarantee the minimum control cost. In the simulation, the adaptive robust control of Sun is chosen as a comparison. The existence of Pareto optimality and the effectiveness of optimal robust control have been verified via simulation results.

Distinct Cytosine Modification Profiles Define Epithelial-to-Mesenchymal Cell-State Transitions
Authors: Lee Min Kyung , Brown Meredith S. , Wilkins Owen , Pattabiraman Diwakar R. , Christensen Brock C.
Published: August 2021

Background: Epithelial-to-mesenchymal transition (EMT) is an early step in the invasion-metastasis cascade, involving progression through a number of cell intermediate states. Due to challenges with isolating intermediate cell states in EMT, genome-wide cytosine modification mechanisms that define transition through EMT states are not completely understood. We measured multiple DNA cytosine methylation modification marks, complemented with chromatin accessibility and gene expression, across clonal populations residing in specific EMT states. Results: Clones exhibiting intermediate EMT phenotypes demonstrated increased global 5-hydroxymethylcytosine (5hmC), decreased 5-methylcytosine (5mC), and more accesible chromatin. Open chromatin regions containing CpG loci with abundant 5hmC were enriched in motifs of key EMT transcription factors, ZEB1 and Snail. The magnitude of altered gene expression in intermediate cell states was higher for genes both with increased gene promoter 5hmC and differentially accessible chromatin compared with genes that exhibited differentially accessible chromatin alone, implicating functional epigenetic duality in regulation of EMT.Conclusion: Our results indicate the importance of both distinct and shared epigenetic profiles at the cytosine and chromatin level associated with EMT processes that contribute to gene regulation and which may be targeted to prevent the progression of EMT.

The most affected disease in recent years is Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) that is notable as COVID-19. It has been started as a disease in one place and arisen as a pandemic throughout the world. A serious health problem is developed in the lungs due to the effect of this coronavirus. Sometimes it may result in death as a consequence of extensive alveolar damage and progressive respiratory failure. Hence, early detection and appropriate diagnosis of corona virus in patient’s body is very essential to save the lives of affected patients This work evolves a Silicon (Si) based label-free electrical device i.e. the reduced graphene oxide field-effect transistor (rGO FET) for SARS-CoV-2 detection. Firstly rGO FET functionalized with SARS-CoV-2 monoclonal antibodies (mAbs). Then the rGO FET characteristic response is observed to detect the antibody-antigen reaction of SARS-CoV-2 with different molar ranges. The developed GFET shows better performance towards the drain current and limit-of-detection (LoD) up to 2E-18 M. Therefore, we believe that an intense response was observed than the earlier developed devices and signifies impressive capability for subsequent implementation in point-of-care (PoC) diagnostic tests.

Authors: Aboelhadid Shawky M , Abdel-Aziz Sahar Abdel Aleem
Published: August 2021

The effect of thymol and ivermectin on the development and embryonation of Toxocara vitulorum (T. vitulorum) eggs, as well as their migration in albino rats was investigated in vitro. A total of forty male albino rats were divided into four groups for an in vivo experiment. The first group was uninfected; the second group was infected but left untreated; the third group received thymol at a dose of 40 mg/kg; and the fourth group received ivermectin (0.2 mg/kg). Thymol inhibited the development of Toxocara larvae within the eggs in vitro. Ivermectin; however, produced inconsistent results. The in vivo results indicated that the recovery rates of Toxocara larvae from the liver and lungs on day 7 post-infection were significantly lower in the thymol- or ivermectin-treated group than in the infected untreated control group. Histopathological examination demonstrated that thymol and ivermectin were effective in reducing larval load, reducing the number and size of granulomas in the absence of larvae, and improving tissue architectures. Albumin levels were significantly increased in the thymol-treated group. Nitric oxide, IL-4, and IFN- γ levels were significantly decreased in the serum of the thymol- or ivermectin-treated group. The current study concluded that thymol possessed anti-Toxocara activity in a rat model. Additionally, thymol possessed ovicidal properties and may be used as a disinfectant.

Background: Acute acquired concomitant esotropia (AACE) is a relatively rare subtype of esotropia that can develop in older children (>5 years) and adults. The etiology of AACE is unknown, but there have been case studies describing risk factors. This study applied multiple regression analysis to explore risk factors and the impact of this subtype's surgical design esotropia and to gain insights into pathogenesis. Methods: Patients with Type III AACE and healthy controls, who were matched for age (±5 years) and refractive diopter (±1 D), were included in this study. All patients were treated between March 2018 to September 2020. We collected information on the number of hours spent performing near work per day, whether the patient wore glasses, and the refractive diopter of both the eyes. We also determined the deviation angles at both near- and far-vision in these individuals. Additionally, we measured the distance from the medial rectus insertion to the limbus in surgical patients.Results: Patients (n=51) with Type III AACE and sixty healthy control persons (n=60) were included in the study. We found that 99.96% of cases and 91.67% of controls had myopia. Among them, 60.8% of cases and 20.0% of controls did not wear glasses for near work. Twelve cases were treated with a prism, and thirty-nine were treated surgically. The average time devoted to near work per day was 7.24±1.91 (range: 4-12) hours and 3.7±1.29 (range: 2-7) in cases and controls, respectively. In univariate and multivariate logistic regression models, Type III AACE was significantly associated with increased hours of near work per day and near work without wearing glasses.Conclusions: Increased hours of near work per day and myopic patients performing near work without glasses are independent risk factors of Type III AACE. A satisfactory result can be obtained by optimizing the foot correction with the maximum and the most stable angles before operation.

Magnetic anisotropy in strontium iridate (Sr2IrO4) is essential because of its strong spin-orbit coupling and crystal field effect. In this study, we investigated the detailed mapping of the out-of-plane (OOP) magnetic anisotropy in Sr2IrO4 for different sample orientations using torque magnetometry measurements in the low-magnetic-field region before the isospins are fully ordered. Dominant in-plane anisotropy was identified at low fields, confirming the b axis as an easy magnetization axis. Based on the fitting analysis of the strong uniaxial magnetic anisotropy, we observed that the main anisotropic effect arises from a spin–orbit-coupled magnetic exchange interaction that affects the OOP interaction. The interlayer exchange interaction results in additional anisotropic terms owing to the tilting of the isospins. Our results are relevant for understanding OOP magnetic anisotropy and provide a new way to analyze the effects of spin–orbit-coupling and interlayer magnetic exchange interactions. This study provides a new insight into the understanding of bulk magnetic, magneto-transport, and spintronic behavior of Sr2IrO4 for future studies.

In biogeochemical cycles,humic substances are natural electron shuttles in transforming the nutrients and environmental pollutants. The complexes of humic acid with macro and micro nutrient metals serve as ecofriendly organo-mineral fertilizer. In this study, lignite extracted humic acid-metal (Fe, Mg, Zn) complexes were prepared and characterized. The proximate analysis exhibited the moisture, volatile matter, ash and fixed carbon contents of extracted humic acid of 02.61%, 17.31%, 57.18% and 22.90% respectively. The% metal ions in humic acid complexes ranges from 3.5-7.25%. The FTIR analysis of coal extracted humic acids-metal complexes showed Zn, Mg and Fe ions complexed in bidentate manner predominantly with carboxylic acid moiety of humic acid. Thermal gravimetric analysis indicated the higher value of humic acid decomposition as compared to their metal complexes. The thermal stability observed order is HA- Zn >HA-Fe>HA- Mg. The X-ray diffraction pattern pointed toward the non-crystalline nature of humic acid and their respective complex’s due to having few intense and some small diffuse peaks in the 2θ range from 0 to 80°.Hence the humic acid-metals complexes increase the soil humic content along the availability of essential nutrient that enhance the loam biotic action.

We previously reported that the Vibrio vulnificus hemolysin A (VvhA) protein elicited good immune protection and could effectively control V. vulnificus infection in mice. However, its molecular mechanism remains unknown. In this study, we found that IL-21 enhances immune protection by inducing a Tfh-cell and germinal center (GC) B-cell response. We used RNA-seq and identified 10 upregulated and 30 downregulated genes that were involved in IL-21-upregulated protection. We also performed Gene Ontology (GO) analysis and pathway analysis of these differentially expressed genes. Our findings indicate that IL-21 can enhance the immune protection effect of VvhA protein and may serve as a novel strategy for enhancing the immune protection effect of protein vaccines.
The language of the empire and the image of the "noble savage" in French travel essays of the second half of the 18th century
Authors: Демичева Т.М.
Published: August 2021

В статье рассмотрен образ «благородного дикаря» на примере очерков о кругосветных плаваниях – «Кругосветном путешествии на фрегате “Будёз” и транспорте “Этуаль”» Луи Антуана де Бугенвиля и «Путешествии по всему миру на “Буссоли” и “Астролябии”» Жан-Франсуа де Лаперуза. Показано, как межкультурный контакт привел к возникновению шаблонов восприятия европейцами «других» народов. Отмечено, что эти очерки способствовали определению места и роли европейцев в мире. Данный шаблон включал как положительные, так и отрицательные элементы. Империя могла извлекать пользу из романтизированного образа «благородного дикаря», тем самым стимулируя новые колониальные захваты. В то же время на практике европейцы находили варваров агрессивными, лживыми и недалекими. Автор приходит к выводу, что межкультурный диалог, показанный во французских очерках о кругосветных путешествиях второй половины XVIII в., вряд ли можно назвать успешным, так как эти травелоги привели к возникновению очередного шаблона, рассматривающего «других» сквозь высоту европейского знания, основанного на привычной для европейского мира системе ценностей.

In the article we use the round-the-world travel essays "Around-the-world trip on the frigate "Boudez" and the transport" Etoile" by Louis Antoine de Bougainville and "Travel all over the world to "Bussoli" and "Astrolabe" by Jean- Francois de La Perouse to show the image of the "noble savage". These travelogues show that the intercultural contact led to the emergence of patterns of perception of "Others" by Europeans. It is noted that travelogues contributed to self-examination and determined the place and the role of Europeans in the world. Moreover, this pattern includes positive and negative elements as well. The empire could have a benefit from a romanticized image of the "noble savage" thereby stimulating new colonial conquests. At the same time, travel essays could contradict the Enlightenment ideas, when Europeans found barbarians to be aggressive, deceitful and dimwitted. The purpose of this study is to consider the problematic aspects of describing "Others" and to define the role of travelogues in imperial politics. We will argue that the intercultural dialogue shown in French round-the-world travel essays of the second half of the 18th century can hardly be called successful. These travelogues led to the appearance of fascinating pattern of "other". That pattern looked at the “others” through the European knowledge based on system of values typical for the European world.
On the Roads from Intra-Ethnic Polyphony to Ethno-National “Symphony”: The Kosovo Myth and Serbian Historians in the 1980s and 1990s
Authors: Ломоносов М.Ю.
Published: August 2021

Этно-исторические мифы признаны одним из важнейших факторов формирования национальной памяти, конструирования идентичности и разжигания межэтнических конфликтов. При этом исследователи часто сосредотачиваются на межгрупповом противостоянии мифотворцев-интеллектуалов и войнах памяти. Такой подход нивелирует внутриэтническое многоголосие и создает представление о национальной памяти как едином целом. Развитие косовского мифа в среде сербских историков партийно-югославистского, национально-патриотического и скептического течений 1980–1990-х гг. иллюстрирует процессы формирования внутрицехового разноречия. Оно также помогает понять, как внутриэтническое разноголосие эволюционирует в этнонациональное единогласие при встрече с Другим.

The scholars of nationalism and memory see ethno-historical myths as important factors in forging national memory, constructing cultural identity, and fueling ethnic conflicts. However, the literature tends to focus on the inter-communal competition between intellectuals, memory wars, and the incompatibility of ethnic claims. This approach neglects intra-ethnic polyphony, thus, contributing to the tendency of seeing “national memory” as a single whole. The case of the famous Kosovo myth in the ranks of Serbian intellectuals of the 1980s–1990s, who belonged to the party-Yugoslavist, Serbian ethno-nationalist and skeptical currents of historical thought, illustrates how intra-ethnic mythopoeic polyphony develops. It also helps to understand how the intra-ethnic polyphony evolves into an ethno-national “symphony” in face of the Other.
