Masehual Siuamej, tejiendo identidad se desenredan diferencias
Authors: Camacho Domínguez Grecia Argel , Marín Mendoza Mariana
Published: June 2022

Bajo las sujeciones del colonialismo, el capitalismo y el patriarcado, las socias del Hotel Taselotzin y la organización Masehual Siuamej Mosenyolchicahuanij (msm) han puesto como principal herramienta de resistencia las alianzas entre mujeres originarias bajo formas de organización político-económicas alternativas. Éstas han determinado tanto sus vidas personales como la vida en comunidad. El presente artículo busca revalorar la manera en la que este proyecto de economía social transformó y resignificó las relaciones entre mujeres indígenas de la msm desde una crítica al concepto de sororidad, rescatando la propia palabra de las mujeres para definir los lazos que han tejido entre ellas para nombrar su lucha y para autodeterminarse. Se realizaron entrevistas semiestructuradas, encuestas de opinión y grupos focales para recabar testimonios y otros datos contextuales. En el recuento de sus historias personales y de sus encuentros colectivos, resaltan palabras como ‘socia’, ‘compañera’ y, en el contexto particular de la pandemia por la COVID-19, ‘hermana’. No obstante, la firme postura de las socias en rechazo al feminismo desde su identidad indígena –no antagonista–, permite sostener que la matriz de conocimientos y valores que orienta las alianzas entre mujeres masehual está más determinada por el Yeknemilis que por los referentes occidentales de la sororidad. Con miras al desenredamiento de las diferencias, se exhorta el uso del desprendimiento epistemológico para encontrar palabras que permitan nombrar los lazos de las socias respetando su profundidad, significado y procedencia.

Authors: Dar Showkat Ahmad
Published: June 2022

Education is one of the most important factors in achieving any country's development objectives. Education has grown dramatically in Jammu and Kashmir in recent years as a result of the use of e-government in this sector. Initiatives in information and communication technology aid in the provision of world-class education. The use of e-governance in the education sector has spawned a slew of new ideas. Among the social sectors, Higher Education is one of the most important sectors for development-government facilities for colleges and universities are implemented and maintained by the Department of Higher Education. E-Government is regarded as critical to improved governance. Institutions around the world are launching E-governance initiatives in order to provide their constituents with more transparent, efficient, and cost-effective services. Kashmir's higher education has conceptualised e-governance projects and service initiatives in the educational system as time has passed. This paper provides an overview of the e-governance services, initiatives, and benefits reaped by establishing these services for stakeholders in Jammu and Kashmir's higher education.
An Analytical Study of the Kushan Rule in Kashmir
Authors: Bhat Rashid Manzoor
Published: June 2022

Kanishka's reign was clearly a time of unprecedented prosperity for Kashmir. There are numerous Kushan art treasures with Buddhist themes scattered throughout the valley, which proves this. The only people who can get to some of these places even now are intrepid explorers. The large number of Kanishka's coins that have been found so far in Kashmir proves this. Vasishka is also known as Vajheshka in records from the time, and it is likely that he was known by this name in Kashmir, which was called Juska until the time of Kalhana. This is another important sign that Kashmir became a famous place in the Kushan empire. In addition to writing about the building projects of the three Kushana rulers and the growth of Buddhism during their time in power, Rajatrangni also mentions Juska's time in power. As the saying goes, "that wise king Jayasvami, who built Juskapura with its Vihara, was also the founder of Jayasvamipura." In this study at attempt has been made to explore and analyse the Kushan rule in Kashmir.

Published: June 2022

Solar energy has been advocated as the substitute for depleting fossil fuels for thermal applications and electricity generation. The research was aimed at determining the performance evaluation of the spiral coil receiver for thermal steam generation using a parabolic concentrating system. The parabolic dish solar concentrator (PDSC) with a rim angle of450C, the focal length of 6.15 m, and an aperture area of 5.8 m2 were designed and constructed for the determination of the variables. The PDSC and spiral coil receiver were made of stainless-steel reflector sheet and copper tube pipe respectively. Since the PDSC is for high enthalpy steam generation, it can be used for hot water and cooking applications. A finite element stress analysis was carried out to determine the thermal and optical efficiency of the system under various weather conditions. The thermal efficiency and optical analysis of the system were determined and obtained to be 54.4%, and 48.6% respectively. The efficiency according to the finding depends on the optical properties of the materials involved, the geometry of the collector, and the various imperfections arising from the construction of the collector.

Cereal grain (Sorghum, millet, and maize) and legumes (beans, soya beans, and groundnut) are the agricultural raw materials used both commercially and traditionally in the production of weaning foods, particularly in developing countries. A variety of cereals (sorghum) are used singly or in combination to produce several fermented and sprouted weaning foods using simple processing methods. The study investigated the effect of sprouting and fermentation on some functional properties and microbiological quality of the food formulations prepared from sorghum (S. bicolor), cowpea (Vigna unguiculata), and groundnut (Arachis hypogea) in a ratio of (70:20:10). Viscosity, functional properties, and microbiological assessment of the food formulations were evaluated using standard laboratory methods of analysis. Sprouting, fermentation singly and in combination significantly (P<0.05) decreased gruel viscosities (197825.1cps – 225.019.4cps) for red sorghum and (1952022.9cps – 230018.6cps) for white sorghum variety. The results of ranged bulk density from (0.700.01g/ml – 0.600.02g/ml) for red sorghum and (0.710.02g/ml – 0.600.02g/ml), while increasing water absorption capacity in sprouted and fermented sorghum samples for (FCR 6.470.00g/ml, FCW 5.430.01) and SCR 6.030.00g/ml, SCW 4.410.02g/ml) compared to raw and the composite blends. Total bacterial counts reduced significantly with sprouting and fermentation. The dominant microorganisms isolated in this study were all fermenters non-pathogenic microorganisms which are safe for consumption Staphylococcus species dominant only in the non-fermented products

Evolution of Prussian censuses in the years 1840–1910: methodology, scope, importance and problems
Authors: Chojecki Dariusz
Published: June 2022

The censuses carried out by the Royal Prussian Statistical Office in Berlin are of particular importance for the historical research of the 19th century population in Prussia, including the lands largely inhabited by people who spoke Polish or Kashubian. Nevertheless, these censuses were not discussed in greater detail. Attention was mainly focused on the reliability of the censuses organised until 1840, and subsequently on matters related to the statistics of the mother tongue. The aim of the article is to show the evolution of the method of census taking, data processing, features implementation and the presentation of the results in the years 1840–1910, with particular emphasis placed on the census of 1871 and its reception among the society, mainly on the Polish lands under German rule. The research is largely based on the monumental Preussische Statistik (Statistics of Prussia), which contains the census documentation and comments provided by provincial authorities. Moreover, normative sources and older studies were used in the study. The article proves that censuses in general evolved until 1871, and then only the studied content featured changes which were discussed and assessed. A revolution in data management was brought by the use of A cards in 1871, which made it easier to perform complex statistical groupings for selected demographic characteristics. The implementation of new solutions was accompanied by the introduction of the principle of self-enumeration. It encountered obstacles, however, especially in the eastern provinces of Prussia, which is primarily associated with the level of education and the knowledge of the German language among the population, mainly its Polish-speaking members. The results presented in the article should prove useful to historical demographers, and social and economic historians.

Published: June 2022

An assessment of Water Quality from Auranga estuary (20°63’ N and 72°820 E) was carried out from January 2019 to December 2019. The hydro-chemical variables were analyzed for the evaluation of water quality showed fluctuation in the estuarine water seasonally. The water quality index was computed for the evaluation of water quality of Auranga estuary; to know the pollution level of water body Index for Pollution was also computed. The water quality index (WQI) was 115.97 at downstream and 85.30 at upstream that indicate poor and good water quality respectively. The Pollution Index (PI) ranges from 1.41 (Downstream) to 0.78 (Upstream) which indicate that the water is medium polluted and slightly polluted respectively. Seasonal assessment showed the discrete water quality index and pollution index based on three different seasons; during winter season WQI was 143.30 and 108.05 and PI was 1.41 and 0.97 at downstream and upstream respectively, during summer WQI was 126.73 and 106.95 and PI was 1.18 and 0.94 at downstream and upstream sites respectively and during monsoon WQI was 97.67 and 88.11 and PI was 0.88 and 0.78 at downstream and upstream sites respectively. Univariate statistical technique is attempted to explain the correlations between the variables.
Energy Recovery in Membrane Process
Authors: Pourkarim Nozhdehi Saeed
Published: June 2022

One way in order to reduction energy consumption and providing the required water in both well-established technologies such as reverse osmosis (RO) and electrodialysis is use of the strengths of two or more processes through hybridization. Other key objectives of hybridization include increasing the capacity of the plant flexibility in operation and meeting the specific requirements for water quality. At this section, has been provided a critical review of hybrid desalination systems, and methods used to optimize such systems with respect to these objectives. For instance, coupling two process like as electrodialysis with RO is very effective in order to overcome the low recovery in RO systems. On the other hand, we can use for two or more processes such as RO with membrane distillation (MD) or zero liquid discharge (ZLD) for treatment of hypersaline feed solutions. At this section, also have been reviewed the applicability of salinity gradient power technologies with desalination systems and we identified the gaps that for effective upscaling and execution and implementation of such hybrid systems need to be addressed.

Published: June 2022

Drug repurposing involves reusing an active pharmaceutical ingredient that is already in the market and drugs that were unsuccessful in their clinical phases of development for a new indication. It has numerous benefits in drug development. Therapeutic inhibitors are agents that could be of synthetic or natural source with the ability to trigger the down-regulation of an enzyme or protein, thereby inducing therapeutic effect(s). Researchers have embraced synthetic methods in searching for therapeutic molecules through structural activity relationships and other means in the past and recent times. Despite these synthetic drugs, the morbidity and mortality rate of ailment and disease affecting humanity remains overwhelming. Research has shown that solutions to these challenges can be attempted through drug repurposing. In the past, natural products in raw forms have been utilized in traditional, complementary medicine to manage and treat diseases and illnesses, as there are molecules in use today as drugs, which originated from plants and other natural sources. Studies on natural products have led to diverse natural product databases that can serve as a source of repurposing agents. There are also databases for protein and enzymes of human origin, which have an enormous role in the in-silico drug repurposing approach.
Climate changes: Challenges and possible solutions
Authors: Barjaktarević Dragana
Published: June 2022

Climate changes are a topic which has been gaining attention of the global scientific and professional public increasingly for years. The question that has been on the agenda of conferences addessing this issue is how much time has left for us and whether a human can emerge as the winner in the struggle against climate changes bearing in mind that nature will always find a way to confront its uncontrolled destruction. With their activities, above all by uncontrolled technological progress (development), humans brought the Earth into the current state. A wish to earn as much profit as possible neglected the fact that economic interest and interest related to the environment can be balanced only by sustainable development. This is why this century will be to a great extent defined by a manner how we deal with climate changes. Since, "effort is pointless if nature confronts", Lucius Annaeus Seneca.
La duplicidad de la acción en la filosofía de Giuseppe Capograssi, a la luz de la noción de experiencia elemental de Luigi Giussani
Authors: Llano Torres Ana
Published: June 2022

La insistencia de Giussani en el alcance crítico de la experiencia me llevó a la filosofía de Capograssi. Este alude reiteradamente a un orden de principios y evidencias profundas, cuya luz permite al sujeto ver las cosas en su verdad, bondad y belleza. La relación entre estas ideas viquianas y la noción de experiencia elemental de Giussani, en su doble nivel óntico y ontológico, se percibe en la duplicidad de la acción que, más allá de su inmediatez, se alimenta de una vis veri, verdadero motor del individuo, de ese yo metafísico que es más de lo que aparenta

Introdução: Os distúrbios de desenvolvimento das estruturas dentárias podem ter sua origem relacionada a fatores hereditários. Essas alterações podem afetar tanto a forma, tamanho, número, posição e função dos dentes.Objetivo: Este estudo tem a finalidade de pesquisar na literatura a respeito da anomalia dentária quantitativa (hiperdontia) avaliando sua incidência, prevalência e enfatizando a importância de um  diagnóstico precoce.Metodologia: Foi realizada uma busca bibliográfica nas bases de  dados SciELO, PubMED, Bireme e Google Acadêmico, ultilizando artigos com textos completos, nos idiomas português ou inglês, compreendidos no período de 2010 a 2020, cujo tema principal correspondesse aos descritores. Foram excluídos os artigos que não estavam disponíveis na integra online. Resultados: Avaliando-se  vários estudos foi possivel identificar uma prevaléncia do acometimento de dentes supranumerários na região da maxila, porém que não houve diferença estatísticamente significante em relação a posição na arcada (esquerdo ou direito). E devido a muitos estudos não realizarem análise estatísticas apenas considerar a frequencia absoluta, a avaliação em relação ao gênero teve resultados variados. Considerações finais: Constatou-se a importância de um diagnóstico precoce na detecção de anomalias dentárias, principalmente através de exames radiográficos, permitindo um planejamento individualizado e tratamento correto no momento ideal para o paciente.
Experimental observation of chiral inversion at exceptional points of non-Hermitian systems

Based on the quantum mechanics, the physical observables are represented by Hermitian linear operators. Derived from the conservation of energy, these Hermitian operators exhibit real eigenvalues. However, when a closed system described by an effective Hamiltonian is coupled with the surrounding environment, the dynamics of the system itself becomes non-Hermitian dynamic. In general, the eigenvalues of an open optical non-Hermitian system are complex. Parity-time symmetric structure is the system composed of complex potentials, which is neither parity symmetric nor time reversal symmetric alone but is symmetric after operations of parity inversion and time reversal have been combined. The eigenvalue of the parity-time symmetric Hamiltonian can be found to be real, despite the non-Hermitian nature of the system. One of the most attractive properties of non-Hermitian system is the exceptional point, which is degenerate at which two or more eigenvalues and eigenstates of a non-Hermitian physical system coalesce. The unique topological features of EPs, forming a self-intersecting Riemann surface, have given rise to several exotic physical properties. As a kind of phase singularity in a physical system, exceptional point of non-Hermitian system gives rise to a plethora of counterintuitive phenomenon, such as the loss-induced transmission enhancement, unidirectional reflection and asymmetric state transfer. Especially, the eigenvectors of exceptional point are self-orthogonal and an inherent chirality can be determined because of the missing dimension. Chirality lies at the heart of the most fascinating and fundamental phenomena in modern physics, and how to impose a strong chirality and a switchable direction of light propagation in an optical system by steering it to an exceptional point is an interesting research topic. In this work, a non-Hermitian system is constructed based on the special metamaterial resonator of split-ring resonator, in which the sign of coupling coefficient can be flexibly controlled. Especially, the chiral inversion at an exceptional point of non-Hermitian system is observed experimentally. This sign of coupling coefficient controlled exceptional point not only paves a new way for studying the fundamental non-Hermitian physics in an open system, but also holds great potential in the applied photonic devices such as the efficient chiral mode converter and chiral antennas.
Quantum readout and gradient deep learning model for secure and sustainable data access in IWSN
Authors: Alzubi Omar A.
Published: June 2022

The industrial wireless sensor network (IWSN) is a surface-type of wireless sensor network (WSN) that suffers from high levels of security breaches and energy consumption. In modern complex industrial plants, it is essential to maintain the security, energy efficiency, and green sustainability of the network. In an IWSN, sensors are connected to the Internet in a non-monitored environment. Hence, non-authorized sensors can retrieve information from the IWSN. Therefore, to ensure that data access between sensors remains sustainable and secure, energy-efficient authentication and authorization are required. In this article, a novel Quantum Readout Gradient Secured Deep Learning (QR-GSDL) model is proposed to ensure that only trustworthy sensors can access IWSN data. The major objective of this QR-GSDL model is to create secure, energy-efficient IWSN to attain green sustainability and reduce the industrial impact on the environment. First, using the quantum readout and hash function, a registration method is designed to efficiently perform the registration process. Next, a gradient secured deep learning method is adopted to implement the authentication and authorization process in order to ensure energy-saving and secure data access. Simulations are conducted to evaluate the QR-GSDL model and compare its performance with that of three well-known models: online threshold anomaly detection, machine learning-based anomaly detection, and dynamic CNN. The simulation outcomes show that the proposed model is secure and energy-efficient for use in the IWSN. Moreover, the experimental results prove that the QR-SGDL model outperforms the existing models in terms of energy consumption, authentication rate, authentication time, and false acceptance rate.

Published: June 2022

Background

Elevated expression and oncogenic functions of cell division cycle associated 2 (CDCA2), an important mitotic regulator, have been demonstrated in several cancer types, however their involvement in hepatocellular carcinoma (HCC) has not been elucidated, and the underlying molecular mechanism remains unclear. This study aims to determine the role of CDCA2 in HCC and the underlying molecular mechanism.

Methods

The expression of CDCA2 in HCC was studied in 40 pairs of frozen and 48 pairs of paraffin-embedded HCC samples and paracancerous normal samples by qRT-PCR and immunohistochemistry, respectively, and using The Cancer Genome Atlas (TCGA) datasets. The cellular function of CDCA2 was studiedin vitroin the HepG2, Huh7 and SK-Hep1 HCC cell lines.

Results

We found significantly upregulated CDCA2 expression in HCC, which was correlated with higher clinical stage, tumor grade and Glypican-3 (+). High CDCA2 expression was correlated with worse overall survival. CDCA2 promoted the proliferation of HCC cells by promoting G1/S transition through the upregulation and activation of CCND1/CDK4/6 and CCNE1/CDK2, enhanced the clonogenic ability, inhibited apoptosis in a p53/p21-dependent manner by inhibiting the p38 MAPK pathway and activating the JNK/c-Jun pathway, and promoted the migration of p53-mutant Huh7 cells by activating the epithelial-mesenchymal transition. Targeting CDCA2 reduced the chemoresistance of HCC cells to cisplatin. CDCA2 expression was also regulated by cyclophilin J.

Conclusions

This study revealed elevated expression of CDCA2 in HCC, possibly as a result of p53 dysregulation, which was associated with worse prognosis of patients. We confirmed the oncogenic role of CDCA2 in HCCin vitroand revealed some of the underlying molecular mechanisms. This study indicated the potential value of CDCA2 as a future target for the treatment of HCC.
Stable nitrogen and carbon isotope compositions in plant-soil systems under different land-use types in a red soil region, Southeast China
Authors: Liu Man , Han Guilin
Published: June 2022

Background

Stable N isotope compositions in plant-soil systems have been widely used to indicate soil N transformation and translocation processes in ecosystems. However, soil N processes and nitrate (${\mathrm{NO}}_{3}^{-}$) loss potential under different land-use types are short of systematic comparison in the red soil region of Southeast China.

Methods

In the present study, the stable N and C isotope compositions (δ15N and δ13C) of soil and leaf were analyzed to indicate soil N transformation processes, and the soil to plant 15N enrichment factor (EF) was used to compare soil ${\mathrm{NO}}_{3}^{-}$ loss potential under different land-use types, including an abandoned agricultural land, a natural pure forest without understory, and a natural pure forest with a simple understory.

Results

The foliar δ15N value (−0.8‰) in the abandoned agricultural land was greater than those of the forest lands (ranged from −2.2‰ to −10.8‰). In the abandoned agricultural land, δ15N values of soil organic nitrogen (SON) increased from 0.8‰ to 5.7‰ and δ13C values of soil organic carbon (SOC) decreased from −22.7‰ to −25.9‰ with increasing soil depth from 0–70 cm, mainly resulting from SON mineralization, soil organic matter (SOM) decomposition, and C4 plant input. In the soils below 70 cm depth, δ15N values of SON (mean 4.9‰) were likely affected by microbial assimilation of 15N-depleted ${\mathrm{NO}}_{3}^{-}$. The variations in δ15N values of soil profiles under the two forests were similar, but the EF values were significant different between the pure forest with a simple understory (−10.0‰) and the forest without understory (−5.5‰).

Conclusions

These results suggest that soil to plant 15N enrichment factor have a great promise to compare soil ${\mathrm{NO}}_{3}^{-}$ loss potential among different ecosystems.
Assessment of Serum Ferritin, CRP and Insulin Levels in First Trimester of Pregnancy as a Predictive Biomarker of Gestational Diabetes Mellitus: A Longitudinal Study
Authors: Chakraborty Mayukh , Sil Amit Kumar , Chakraborty Sanghamitra
Published: June 2022

Introduction: Gestational Diabetes mellitus (GDM) increases the risk of foetal morbidity and mortality heralding the future risk of development of type 2 diabetes in mother. GDM develops mainly due to insulin resistance along with interplay of risk factors like advancing maternal age, family history of diabetes, obesity, ethnicity, history of macrosomia. Aim: To detect whether estimation of serum ferritin, C-reactive protein and insulin in 1st trimester can predict the subsequent occurrence of GDM and whether susceptible mothers can be managed cautiously to prevent foeto-maternal complications. Materials and Methods: This hospital-based longitudinal study was done in Department of Gynaecology and obstetrics in collaboration with the Department of Biochemistry, Medical College and Hospital, Kolkata, West Bengal, India, from January 2018 to June 2019. The study included 80 antenatal mothers attending the Antenatal Outpatient Department in first trimester. The blood samples were collected from them during first trimester and serum ferritin, C-reactive Protein (CRP) and insulin were estimated using different methods as specified later. The anthropometric measurements of the mother {Body Mass Index (BMI), skin fold thickness and waist hip ratio} were measured. These enrolled study participants have undergone Oral Glucose Tolerance Test (OGTT) with 75 gm of anhydrous glucose at 24-28 weeks of gestation. The performance parameters like sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio of ferritin and CRP was calculated. Results: The mean age of participants who developed diabetes (n=12) 25.75±2.92 and who did not developed diabetes (n=68) 23.91±3.74 years. There was 15% prevelance of GDM in study population. The median concentration of serum ferritin and CRP was significantly higher in patients who developed GDM (n=12) among the study population (n=80). The sensitivity of serum ferritin {83.33% (95% confidence interval=51.59-97.91%)} was higher in comparison to C-reactive protein {31.82% (95% CI=13.86-54.87%)}. Conclusion: There was a remarkable decline of insulin sensitivity with the advancement of pregnancy. This implies that latent insulin resistance may start from first trimester and screening in high risk ethnicity group like India should be a routine protocol.
Uncommon Pathological Presentations of Mature Cystic Teratoma: A Case Series
Authors: Pant Suchita , Joshi Usha , Joshi Kriti
Published: June 2022

Mature cystic teratomas are benign tumours of the ovary but rarely certain unusual gross and microscopic findings might complicate their diagnosis or may have an impact on their clinical outcome. Here, we are presenting a case series of five unusual pathological presentations of mature cystic teratomas of ovary. Out of five cases, three cases were of collision tumours, in which combination of mature cystic teratoma is seen with mucinous cystadenoma in two cases, and with serous cystadenoma in one case. True collision tumours are defined as histologically distinct neoplasms in the same tissue or organ without any histologic admixture or intermediate cell population zone between two components. These tumours are located in various organs but ovarian location is rare. Mature cystic teratoma is the most common component of collision combinations in the ovary. All classes of ovarian tumours, benign, borderline and malignant may collide and therefore, clinical outcomesin collision tumours depend on individual tumour characteristics. Fourth case was of a mature cystic teratoma associated with a distinct hemangiomatous component. Mature cystic teratoma associated with prominent hemangiomatous component is a very rare finding with only few case reports in the literature and it should be differentiated from true ovarian hemangioma, lymphangioma and angiosarcoma. Fifth case was of bilateral mature cystic teratomas associated with a well-defined lipomatous lesion in right sided mature cystic teratoma mimicking lipoma. Lipomatous ovarian lesions are very rare and mature cystic teratoma with prominent adipocytic proliferation is also an exceedingly uncommon finding and it should be differentiated from true ovarian lipoma and other atypical lipomatous proliferations. Most of these tumours remain clinically and radiologically unrecognized, therefore their histological recognition is essential for adequate patient management.
