Application of a Vertical “Electric Sieve” to Mitigate and Prevent Salinization in Coastal Soil
Authors: Li Yuehua , Zhao Lin , Huang Menglu , Chen Liang
Published: October 2021

This study explored the application of a Vertical Electrokinetic system
(V-EK) with multilayer electrodes in shallow soil to form an “Electric
Sieve” to mitigate and prevent the soil salinization caused by salts
rising from shallow groundwater in the coastal areas. In the model V-EK
system, the electric resistances of soil column, reversely corresponding
to salinity, at the applied voltages 4, 10 and 20 V were 266, 487 and
1272 Ω, respectively. Meanwhile, lower electrical conductivity (EC,
between 67-230 μs/cm) were observed in the soil within 50 cm below the
surface at the voltages of 10 V and 20 V, which was much lower than the
minimum value (581 μs/cm) of the control with no current applied. For
the control column without EK treatment (0 V), soil in the surface layer
had the highest EC value at 1721 μS/cm due to the salts rising from the
bottom, and the EC values of soil beneath the surface were in the range
of 581-1127 μS/cm. Compared to control column, the level of ions in the
surface soil significantly declined after V-EK treatment, especially for
the column with voltage at 10 V and 20V. When voltage was at 20 V, Na+
was detected at a range of 0.06-0.08mg/g in the surface soil, a
>99% reduction when compared to the controls. Similar
efficacy was observed for chloride (Cl-), in the V-EK column with the
voltages at 10 V and 20V.

Radiomics features for differentiating clear cell sarcoma of the kidney from Wilms’ tumor in children based on contrast-enhanced computed tomography: a case-control study
Authors: Wang Haoru , Chen Xin , Ding Hao , Zhu Jin , Zhang Li , Zhang Ting , Yu Wenqing , He Ling
Published: October 2021

Background: Clear cell sarcoma of the kidney (CCSK) is a rare but the
second common renal malignant tumor mimicking Wilms’ tumor. Radiomics is
helpful for differentiating CCSK from Wilms’ tumor preoperatively
through analyzing the pixel distribution of lesions on medical images
quantitatively. Procedure: In this study, the regions of interest (ROIs)
of lesions were delineated on corticomedullary phase (CMP) and
nephrographic phase (NP) images to extract radiomics features.
Dimensionality reduction and Logistic Regression (LR) algorithm were
used to construct the classification models. The area under the receiver
operator characteristic curve (AUC), sensitivity and specificity were
calculated for evaluation, and Delong test was used to compare the
performance of the most meaningful features and LR models. Results:
Lower skewness was observed in Wilms’ tumor, and higher skewness in
CCSK. Skewness transformed by exponential and squareroot filters from NP
images achieved moderate to good diagnostic performance for CCSK with
AUCs of 0.707 (95%CI: 0.573, 0.840) and 0.705 (95%CI: 0.572, 0.839) in
the training set, and 0.818 (95%CI: 0.608, 1.000) and 0.803 (95%CI:
0.585, 1.000) in the validation set, respectively. Delong test showed no
significant difference between LR model, exponential-skewness and
squareroot-skewness based on NP images in both training and validation
sets. Conclusion: Skewness from nephrographic phase at exponential and
squareroot filters is helpful to discriminate between CCSK and Wilms’
tumor in children, and higher skewness on NP images may be a potential
imaging biomarker for diagnosing CCSK from Wilms’ tumor.
Evaluating biological activity of folic acid-modified and 10-hydroxycamptothecin-loaded mesoporous silica nanoparticles
Authors: Zhao Mei-Xia , Chen Di-Feng , Zhao Xue-Jie , Li Lin-Song , Liu Yong-Fang
Published: October 2021

Targeted nanocarrier can selectively deliver anti-tumor drugs to cancer
sites improving drug efficiency. Accordingly, a targeted nanocarrier
(MSN-FA) was synthesized based on folic acid (FA) modified mesoporous
silica nanoparticles (MSNs). These loaded with 10-hydroxycamptothecin
(HCPT) to obtain the nano-drug MSN-FA@HCPT. These nanocarriers were
characterized by transmission electron microscopy (TEM), zeta potential,
ultraviolet-visible spectroscopy (UV-Vis), fourier transform infrared
spectroscopy (FT-IR), and thermogravimetric analysis (TGA). Notably, the
nanocarriers were nearly spherical before and after loading HCPT and
exhibited good dispersibility. Also, folate receptor (FR)
over-expressing HeLa cells and FR deficient HepG2 cells were used to
evaluate in vitro cellular uptake and cytotoxicity of MSN-FA@HCPT and
MSN@HCPT. Interestingly, FA-modified nanocarriers enhanced the
cytotoxicity of HCPT by improving drug targeting to tumor cells. Also,
apoptotic and mitochondrial membrane potential (MMP) reducing effects of
MSN-FA@HCPT were more prominent than the MSNs without FA modification.
MSN-FA@HCPT can be excellent drug carriers with profound biomedical
applications.
A study on the allelopathic tolerance of garden pea varieties to Sorghum halepense (L.) Pers. extracts
Authors: Georgieva Natalia , Kosev Valentin , Kalapchieva Slavka
Published: October 2021

The present research study identified garden pea varieties with pronounced
tolerance to the allelopatic action of Sorghum halepense. Nine varieties
were selected to study the effects of shoot and root weed biomass, applied
in three extract concentrations (1, 5 and 10%), on seed germination and
initial germ growth. A variance analysis of data revealed significant
influence (p <0.05) of three studied factors (variety, type and
concentration of extracts) on the investigated parameters. Statistically
insignificant was only the influence of extract type (root/aboveground
biomass) on seed germination. Based on absolute values of the allelopathic
indicator RI, which determines the degree of allelopathic inhibition in
terms of germination, germ length and weight in different varieties, the
variation was as follows: from -0.30 to -0.04, from -1.31 to -2.96 and from
-0.47 to 0.02. The total effect of allelopathic action of S. halepense on
all studied parameters, presented as a GGE-biplot analysis, defined
Pulpudeva and Puldin varieties as exhibiting higher tolerance, in contrast
to Denitsa and Vyatovo, which were sensitive. Ran I, Mira, Musala and
Vechernitsa occupied an intermediate position. Cultivation of allelopathic
tolerant varieties is a promising addition to the current weed control
strategy, especially in organic production.

Authors: Nosek Igor , Boban Jasmina , Vlahovic Dmitar , Radovanovic Biljana , Kostic Dejan , Kozic Dusko
Published: October 2021

Introduction. Neuromyelitis optica spectrum disorder (NMOSD) represents an immune-mediated neuroinflammatory syndrome, classified as a separate entity after the discovery of aquaporin-4 immunoglobulin G (anti-AQP4-IgG). The magnetic resonance neuroimaging spectrum of NMOSD classically consists of bilateral optic neuritis and longitudinally extensive transverse myelitis (LETM), recently broadened with lesions in area postrema, diencephalon, brainstem and cerebellum, and extensive cord atrophy. Case report. The case presents an anti-AQP4 autoantibody-positive 65-year-old female patient who initially presented with underestimated LETM and developed multiple cerebral and cerebellar lytic demyelinating lesions associated with acute long segment op-tic nerve involvement two years later. Two new imaging findings were described in this case: the involvement of a complete cross-sectional area of pons and microhemorrhage in the pons and corpus callosum. Conclusion. Raising suspicion of NMOSD is of crucial importance in cases with isolated LETM in order to prevent relapses in anti-AQP4-IgG positive cases and improve patient outcomes and recovery.

OBJECTIVE

Type 1 and type 2 diabetes are associated with gut dysbiosis. However, the relationship between the gut microbiota and latent autoimmune diabetes in adults (LADA), sharing clinical and metabolic features with classic type 1 and type 2 diabetes, remains unclear. Here, we used a multiomics approach to identify the characteristics of the gut microbiota and metabolic profiles in patients with LADA.

RESEARCH DESIGN AND METHODS

This age- and sex-matched case-control study included 30 patients with LADA, 29 patients with classic type 1 diabetes, 31 patients with type 2 diabetes, and 29 healthy individuals. The gut microbiota profiles were identified through the 16S rRNA gene, and fecal and serum metabolites were measured through untargeted liquid chromatography-mass spectrometry.

RESULTS

Patients with LADA had a significantly different structure and composition of the gut microbiota and their metabolites as well as a severe deficiency of short-chain fatty acid–producing bacteria. The gut microbiota structure of the patients with LADA was more similar to that of patients with type 1 diabetes who were positive for GAD antibody. We identified seven serum metabolite modules and eight fecal metabolite modules that differed between the LADA group and the other groups.

CONCLUSIONS

The characteristic gut microbiota and related metabolites of patients with LADA are associated with autoantibodies, glucose metabolism, islet function, and inflammatory factors, which may contribute to the pathogenesis of LADA. Future longitudinal studies should explore whether modulating the gut microbiota and related metabolites can alter the natural course of autoimmune diabetes in the quest for new therapeutics.

The COVID-19 pandemic made its mark on the entire world, upending economies, shifting work and education, and exposing deeply rooted inequities. A particularly vulnerable, yet less studied population includes our youngest children, ages zero to five, whose proximal and distal contexts have been exponentially affected with unknown impacts on health, education, and social-emotional well-being. Integrated administrative data systems could be important tools for understanding these impacts. This article has three aims to guide research on the impacts of COVID-19 for this critical population using integrated data systems (IDS). First, it presents a conceptual data model informed by developmental-ecological theory and epidemiological frameworks to study young children. This data model presents five developmental resilience pathways (i.e. early learning, safe and nurturing families, health, housing, and financial/employment) that include direct and indirect influencers related to COVID-19 impacts and the contexts and community supports that can affect outcomes. Second, the article outlines administrative datasets with relevant indicators that are commonly collected, could be integrated at the individual level, and include relevant linkages between children and families to facilitate research using the conceptual data model. Third, this paper provides specific considerations for research using the conceptual data model that acknowledge the highly-localised political response to COVID-19 in the US. It concludes with a call to action for the population data science community to use and expand IDS capacities to better understand the intermediate and long-term impacts of this pandemic on young children.

Published: October 2021

The purpose of this article is to consider the characteristics and classification of mechanisms for implementing the principles of the rule of law. Such mechanisms should become the object of purposeful formation. The principles of the rule of law in modern societies cannot be implemented "automatically", it is necessary to outline the directions of work on the implementation of such realization precisely within the framework of unified mechanisms as complexes of applied means and the activities of relevant subjects. To achieve this goal, it seems necessary to define these mechanisms as tasks, to consider the specific characteristics that mechanisms for implementing the principles of the rule of law should have, including modern Russia; to divide these mechanisms on essential grounds.  It has been assumed to use several research methods to solve the tasks set: logical (description, classification), formal-dogmatic, comparative. As a result of the study, it has been revealed that the mechanisms for implementing the principles of the rule of law should be a set of tools, technologies, and procedures for such implementation, as well as the entities implementing this realization.

Identidades judías en la Europa tardoantigua: Erwin Goodenough y sus ecos
Authors: Laham Cohen Rodrigo
Published: October 2021

El objetivo de este trabajo es presentar, por un lado, el derrotero historiográfico de los debates en torno al tipo de judaísmo que existía en Europa en la Antigüedad Tardía y, por el otro, desarrollar algunas definiciones sobre el camino que consideramos adecuado para recuperar la historia de los colectivos judíos europeos tardoantiguos. El texto se estructura en torno a la obra de Erwin Goodenough, quien tempranamente puso en entredicho la tesis tradicional que concebía una rápida expansión del movimiento rabínico, tanto en Palestina como en la Diáspora y, además, consideró la persistencia de un judaísmo alternativo, de corte helenístico y místico, hasta bien avanzada la Antigüedad Tardía. Se indagan, también, otras respuestas ensayadas en tiempos más cercanos, siempre en relación con la vida de los judíos y las judías en la Europa tardoantigua.

The benefits of manual therapy and active cervical exercises in pacients with cerviogenic headache
Authors: Lalu Manuela , Mihancea Petru , Marcu Olivia Andreea
Published: October 2021

Introduction: Cervicogenic headache stems from a dysfunctional mechanism that frequently affects the upper region of the cervical spine, often involving multiple tissues connected with the occipital, submandibular, and orofacial region.

Objectives: The main objective of this study is to demonstrate the therapeutic effectiveness of a personalized program of manual therapy and specific exercises in patients with cervicogenic headaches.

Material and Methods: The study included 44 patients. Specific functional tests of the cranio-cervical-mandibular complex, namely the evaluation of the cranio-cervical-mandibular complex (according to Rocabado), cervical flexion-rotation test, cervical flexor endurance test, cervical extensors endurance test, and palpation of trigger points and cervical spine dynamics, were employed.

Results: The analysis of demographic data shows a significantly increased prevalence of headache among women. The symptomatology that almost always accompanies episodes of cervicogenic headache is localized neck pain. The intensity and frequency of the symptoms are strongly associated with alterations in the dynamics of the upper cervical spine and chronic sleep disorders.

Conclusion: Cranio-cervical manual therapy has proven effective in patients with cervicogenic headaches. The implementation of a strategy based on manual therapy and active exercise had a superior statistical and clinical result compared to the exclusively manual therapeutic approach.

Making the World Safe for Patriarchy: Trump and the Zombie Apocalypse
Authors: Nuckolls Charles W.
Published: October 2021

Both Donald Trump in the White House and zombies in American fiction, movie, and television serials, highlight changes in American social structures, especially marriage and childbirth. Instead of a critique of such structures, however, the zombie genre largely reinforces traditional norms. To be sure, Trump himself is not a zombie, although his followers are often represented the living dead in American political cartoons. What is the connection between the two? In the first place, zombie fiction can be viewed as culturally conservative in orientation, because of its emphasis (whether intentionally or not) on the traditional nuclear family. Second, zombies, almost by definition, do not have a leader, except that the genre deliberately toys with this theme in one recent television series. This paper discusses the two themes – crowds that become like zombies and leaders who create zombie-like followers – in the context of the genre’s overall conservative critique.
The Gender Gap Index in an upcoming urbanized society: A case study of Sehore Municipal Council, Madhya Pradesh, India
Authors: Siddiqui Farheen , Parveen Shahnaz
Published: October 2021

Though urbanization promotes development, the gender gap is being perceived in many socio-economic aspects, in the Indian urban economic scenario. With a 31.16% urban population (in 2011), India has experienced a lopsided development of its urban hierarchy in favour of metropolitan growth which accommodates 42.31% of the total urban population. For various socioeconomic reasons it has a declining female economic participation rate. Sehore M.C. (Madhya Pradesh), an upcoming Class I city, located near the metropolitan cities of Bhopal and Indore, is showing perceptible changes in female work participation, indicating a potential for development in Sehore M.C. along with other smaller cities in Madhya Pradesh. Based on the methodology for the Global Gender Gap Index (GGGI, WEF 2018), the ward wise figures for Sehore M.C. for the partly adopted subindices of Survival, Social, and Economic Participation were calculated using local area indicators from standard international and national agencies to bring out the inter-ward variations in gender gap for Sehore M.C.. Spatial mapping of GGI showed that approximately 91% of wards belonged to the high category but 9% of wards were from the medium category. Suggestions for the promotion of gender parity in the city are made for the overall empowerment of females in Sehore M.C. within the constraints of an urban economic scenario.
Internal migration, rural livelihood strategies and sustainable forest management: Evidence from Bench Maji, Kaffa and Sheka Zones, South West Ethiopia
Authors: Chanie Mulatie , Aleme Timkete
Published: October 2021

In south west Ethiopia, the numbers of immigrants from other parts of the country have been large over the last few years. This huge migration is considered to be a fundamental factor in the degradation of the natural forest because of the livelihood strategy difference of non-migrants and migrants. Thus, we investigated the link between internal migration, rural livelihood strategies and sustainable forest management in the study area. The study investigated the effect of internal migration and peoples’ livelihood strategy choice on sustainable forest management systems. The research was based on both primary and secondary data. The primary data was collected from 392 household questionnaires. The descriptive analysis was supported with an empirical analysis using a multinomial logistic regression model. Internal migration is high because of push and pulls factors related to the migrant people. In addition, there is a livelihood choice difference between migrants and non-migrants. Migrants choose farm activities rather than a forest based livelihood means relative to non-migrants. These high population pressure and livelihood choice differences coupled with weak institutional frameworks have created a burden on the natural forest. Thus, informed policy options regarding internal migration, livelihood strategies and sustainable forest management would be a useful approach to reducing the burden on the natural forest.
Assessment of the seasonal variations in hydrochemistry of Oued Fodda dam, Algeria
Authors: Bouderbala Abdelkader
Published: October 2021

This study was carried out on the surface water of Oued Fodda dam in western Algeria, and aimed to evaluate the seasonal variations of chemical characteristics with the aim to define the processes controlling the mineralization of surface water in this dam. The results showed significant variations in the majority of parameters during the study period from 2009 to 2013, indicating slightly alkaline water, and a SO4-Cl-Ca-Mg water type. Principal component analysis (PCA) and cluster analysis (CA) were used to explain the correlations between the parameters analysed, and the probable sources of surface water contamination. The calculation of saturation indices (SI) of water indicated undersaturated water with respect to halite (NaCl), and equilibrium with respect to the other minerals. While, the temporal variation of physico-chemical parameters such as EC, TDS, SO4
2-, Cl-, Ca2+, Mg2+ indicated a reverse adjustment between physico-chemical parameters and water volumes (WV) in this dam, which can be explained by the weathering of silicate and carbonate minerals, these were justified by the use of ionic ratios, diagrams and scatter plots and multivariate statistical techniques. Conversely, evaluation of the organic water pollution level in this dam showed a water quality from moderately to severely polluted.
Who generated the loopholes? A case study of corporate tax advisors’ regulatory capture over anti-tax avoidance legislation in Finland
Authors: Finér Lauri
Published: October 2021

Recently welfare economists and international political economy scholars have increasingly discussed how the corporations seek profits by corroding policies that tackle tax avoidance and undermine public interest. This article contributes to these discussions on so-called regulatory captures in the global wealth chains by providing a comprehensive case study on anti-tax avoidance legislative processes in Finland. The author analyzes the statements that various stakeholders provided during several phases of enacting the interest deduction limitation rule that targets so-called thin capitalization arrangements. Because of this specific research material, the author is able to undertake a nuanced analysis in describing how and whose statements made the difference from the draft version of legislation to the final wording of the law. The evidence suggests corporate interest groups and tax advisory firms influenced the content of the rule as notable tax base eroding loopholes have been included in the Finnish anti-tax avoidance rule. The author also assesses remedies of regulatory captures.

Published: October 2021

El presente trabajo tiene por objeto dar una mirada panorámica al procedimiento sancionatorio ambiental y su control judicial desde la perspectiva del respeto a las garantías procesales de los administrados sometidos a la potestad sancionatoria de la Superintendencia del Medio Ambiente. Se analiza la siguiente pregunta: ¿entregan el sancionatorio ambiental y su control judicial elementos suficientes para la protección del debido proceso? La hipótesis que se esgrime es que, pese a que el procedimiento administrativo sancionador ambiental y su control judicial ha incorporado relevantes avances relativos al aseguramiento del debido proceso, siguen existiendo severas limitaciones tanto a nivel administrativo como judicial respecto a la protección de las garantías procesales de los administrados, carencias que se ven agravadas por la magnitud de las sanciones en la regulación ambiental.
The Effects of Divided Attention on Memory for Road Signs
Authors: Foster Nathaniel L. , Bell Gregory R.
Published: October 2021

We examined incidental learning of road signs under divided attention in a simulated naturalistic environment. We tested whether word-based versus symbol-based road signs were differentially maintained in working memory by dividing attention during encoding and measuring the effect on long-term memory. Participants in a lab watched a video from the point of view of a car driving the streets of a small town. Participants were instructed to indicate whether passing road signs in the video were on the left or right side of the street while either singing the Star-Spangled Banner (phonological divided attention) or describing familiar locations (visuospatial divided attention). For purposes of analysis, road signs were categorized as word signs if they contained words (e.g., a STOP sign) or as symbol signs if they contained illustrations or symbols (e.g., a pedestrian crosswalk sign). A surprise free recall test of the road signs indicated greater recall for word signs than symbol signs, and greater recall of signs for the phonological divided attention group than the visuospatial divided attention group. Critically, the proportion of correct recall of symbol signs was significantly lower for the visuospatial divided attention group than the phonological divided attention group, p = .02, d = 0.63, but recall for word signs was not significantly different between phonological and visuospatial groups, p = .09, d = 0.44. Results supported the hypothesis that visuospatial information—but not phonological information—is stored in working memory in a simulated naturalistic environment that involved incidental learning.
