Published: January 2021

This paper gives consideration to the three-component FeO–MgO–TiO2 system that is a part of the four-component MgO–Al2O3–FeO–TiO2 system which serves to produce materials with valuable properties. The structure of binary FeO–TiO2 and MgO–TiO2 systems is described and the available data on the FeO–MgO–TiO2 system are analyzed. We present the thermodynamic data on all system compounds and calculate change of the free Gibbs energy in the temperature range of 800 to 1900 K for three exchange reactions. It was established that the triangulation of the FeO–MgO–TiO2 system changes in three following temperature ranges: at the temperatures of up to 1115 К, at 1115 to 1413 К (the restructuring of conodes here occurs) and above 1413 K (stable pseudobrookite is formed). It was shown that the following two-phase equilibria are stable: MgTi2O5–FeTiO3, FeTiO3–MgTiO3, MgTiO3–Fe2TiO4, Fe2TiO4–Mg2TiO4 and Mg2TiO4–FeO at the temperatures of up to 1115 K; MgTi2O5–FeTiO3, FeTiO3–MgTiO3, FeTiO3–Mg2TiO4, Fe2TiO4–Mg2TiO4 and Mg2TiO4–FeO in the temperature range of 1115 to 1413 K; and MgTi2O5–FeTi2O5, MgTi2O5–FeTiO3, FeTiO3–MgTiO3, FeTiO3–Mg2TiO4, Fe2TiO4–Mg2TiO4 and Mg2TiO4–FeO at the temperatures of above 1413 K.

We studied the processes of desulfurization of phosphoric acid obtained by wet process from washed and roasted concentrate and subsequent purification of acid from bivalent and trivalent metals and fluorine via partial ammonization (at pH of 2 to 4). Purified ammoniated slurry containing 16.96% P2O5, 8.06% N, 0.09% CaO, 0.58% MgO, 0.004% Fe2O3, 0.031% A12O3, 0.78% SO3 and 0.52% F was fabricated by the removal of precipitates at the stages of desulfurization and partial ammonization. The rheological properties of ammoniated slurry with 40% moisture were studied. When the temperature is increased from 40 to 800C, both the density and viscosity decrease from 1.395 to 1.365 g cm–3 and from 80.8 to 48.7 cP, respectively. Ammoniated suspension with pH of 5.5 and 8.5 was applied to prepare mono- and diammonium phosphates with the ratio P2O5:N of 52:14 and 48:18, respectively. The sludge obtained after desulfurization and ammonization processes can be used as a slow-release fertilizer.

The conditions for preparation of a composite hydrogel based on polyacrylamide and gelatin, which is reinforced with polypropylene microfiber, were determined to increase its strength. The conditions of modification of polypropylene microfiber were established under which its surface is hydrophilized, which was confirmed by a significant increase in the water retention of microfiber by 11.0–15.2 times. Under the same conditions, an increase in the values of the hydrogen component of free surface energy on planar samples of polypropylene was observed (from 2.81.0 mN m–1 to 29.81.0 mN m–1). Optimal conditions (minimum limits of component concentrations, temperature range, and pH of a medium) were determined, under which a hydrogel based on polyacrylamide and gelatin with satisfactory physicochemical and mechanical properties can be formed. A composite hydrogel, based on polyacrylamide and gelatin reinforced with modified polypropylene microfiber, was prepared. It was found that the introduction of modified microfiber increases the limits of the beginning of destruction from 20–30 to 130 kPa. The results of the investigation of the drug release from the hydrogel indicated that the obtained composites can be used as matrices to create a hydrogel therapeutic bandages with the function of prolonged drug delivery.

Published: January 2021

Thyroid dysfunctions have been associated with maternal-fetal development abnormalities. The evidence about the influence that thyroid dysfunctions can have on delayed conception is not very numerous. However, the benefit of a systematic screening of such alterations is not well established. The main objective is to determine if thyroid dysfunctions are associated with delays in conception in patients treated in an obstetric clinic.
Whisper voice test for screening of hearing loss in nursing home residents with cognitive impairmen
Authors: Vázquez-Sánchez Covadonga , Gigirey Luz Mª
Published: January 2021

Recent studies establish association between hearing loss and cognitive function and evidence exist that hearing damage can exacerbate the negative impact of cognitive impairment in quality of life. Prevalence of hearing loss increases among elderly people living in nursing homes, but the number of residents without hearing aids is high. Whisper voice test is a valid test for screening for hearing impairment. It is frequently used in Primary Care. We applied the voice test in older residents with cognitive impairment and we observed that these subjects failed the repetition of letters. Consequently, we decided to modify the habitual test procedure and employ familiar phrases as screening sound stimulus, on the assumption that they are more easily recognizable. The objective of our study is to establish whether this new technique can be used to screen for hearing loss in older people with mild-moderate cognitive impairment. 62 older residents (mini mental scores > 14) participated in this research. First results reveal that the voice test has high sensitivity and specificity, as well as elevated positive and negative predictive values. The proposed technique could be used as hearing screening tool in a population with similar characteristics.
Associations between kinesiophobia, performance and functionality in patients with freezing of gait and Parkinson
Authors: Martín Núñez Javier
Published: January 2021

Parkinson´s Disease is the second most common neurodegenerative movement disorder worldwide and the first one in Europe, with a prevalence increasing with age. Freezing of gait is a motor disorder which fundamentally causes a block of lower limb, during this espisode patients can not generate a step. Furthermore, freezing of gait is one of the most motor disabling motor disorder in Parkinson´s Disease, being related to the progression of the disease and sometimes with the appearance of complications. Those complications can include increase fall risk, impairment of activities of daily life and reduction of quality of life; due to the related decrease in movement and physical activity in patients with Parkinson´s Disease and freezing of gait. Despite others studies have shown a relationship between kinesiophobia, physical activity and functionality in patients with Parkinson´s Disease, there are no evidences of this link in patients with Parkinson´s Disease and freezing of gait in ``On´´ state.
Sub-national Local Autonomy Index in Urugua

Published: January 2021

Local autonomy and the relationship between levels of government has been an important topic of various disciplines and public policies. The recent application of a local autonomy index in Europe (Ladner, Keuffer and Baldersheim, 2016; Ladner et al., 2019), is an important advance for the measurement of autonomy from a multidimensional perspective, including fiscal, political, legal and organizational aspects. This article expands this research agenda with a perspective that allows us to capture the subnational differences of local autonomy in Uruguay. The patterns of the Provincial Governments in their levels and types of autonomy are analysed, as well as the relevant variables for different dimensions identified, applying exploratory data analysis techniques.

Authors: Guitierrez Pinto Darci
Published: January 2021

The research carried out in a period of two years, in the district of Cerro Colorado starts from the possibility of incorporating the values found in permaculture towards the development of a sustainable habitat in the studied sector, with an area of 174.51 ha and a population of 197,954 inhabitants, containing this territory both urban and rural areas, which makes the proposed methodology have several interconnected layers, ranging from the social-anthropological to geography and demography, to show the superposition of territorial domains. On the other hand, territorial plans have different scales that comprise a certain range of density of inhabitants, their components being mostly dimensional, where the so-called invisible structures are not considered. The investigation had concrete results, such as the social segregation generated and the lack of protection in landscaped areas, concluding that, among other aspects, there is no support for agriculture and that there are no housing development plans.

Authors: Cruz-Meléndez Christian , Aguillón Chávez Aguillón
Published: January 2021

Open Government emerged in 2009 as a new paradigm of public administration and a new way of dealing with public affairs, based on the pillars, Transparency, Participation, Collaboration, Innovation and Accountability. Local governments have also joined in this effort; however little is known about what is happening in the municipalities of Indigenous Normative Systems. This paper analyzes the creation of the Lachibaa Community Museum, in Magdalena Apasco, Oaxaca, as a Collaborative process (pillar) of the current Open Government approach. It is explored how Open Government can be present in indigenous municipalities, which have a special legal regime that recognizes and respects their uses and customs.

Background: The Health and well-being of older Canadian adults have been extensively studied; however, less is known about the health and well-being of older Canadian adults with a disability. Objective: This study was done to determine if participation in leisure and social activities has a significant independent effect on the overall health and life satisfaction of older Canadian adults with a disability. Methods: A secondary analysis of cross-sectional data from the 2006 Participation and Activity Limitation Surveys (PALS) was performed. Respondents were those who reported disability and were at least 65 years of age at the time of the PALS 2006 (n=7,500, representing 1,755,870 Canadians). “Participation in social and leisure activities” was measured based on four types of activities outside the home in 12 months prior to the survey. The single-item measure of self-rated health was used to measure overall health. Life satisfaction was measures based on five items. Weighted data were used to describe the target population. Two sets of multivariate logistic regressions were conducted based on data for the total sample, and separately for men and women using bootstrapped weights. Results: A significant independent effect of participation in leisure and social activities on the general health and life satisfaction of older Canadians with a disability, for both men and women, was confirmed. Conclusion: Participation in leisure and social activities is a potential venue to enhance the health and well-being of older Canadian adults with a disability.

Objective: Many deaf adolescents tend to show more aggression, due to their less social and emotional skills. This also affects their self-evaluation and self-esteem. Life skills are related to the personal, intellectual, emotional, and physical development of an individual. The present study was done to examine the effectiveness of a life skills training program on improvement of the self-esteem and aggression control of deaf adolescents girls. Methods: This quasi-experimental study with a pre-test and post-test design using a control group Was done on 34 female deaf adolescents who were studying in first, second, and third grade of high school in Nezam Mafi High School, Tehran, Iran. Participants were selected using a purposive convenience sampling method and were randomly divided into two groups (experimental and control groups). The Coopersmith Self-Esteem Inventory (SEI) and the Buss-Perry Aggression Questionnaire (AQ) were used to collect data. The life skills training program was delivered to the experimental group in eight 60-min sessions. Results: The results showed that the eight sessions of life skills training program significantly increased self-esteem (P<0.001) and decreased aggression of the experimental group of deaf adolescents girls (P<0.001) while there was no change in the control group. Conclusion: According to the results, it can be concluded that life skills training should be considered as a method for improving the mental status of deaf adolescent girls. Since there may be less social experiences in deaf adolescents, a training program may help them to achieve more self-esteem skills and be more successful in social communications.

Conclusão: O estudo evidencia que o câncer de pâncreas tem uma repercussão extremamente negativa, visto que a maioria dos pacientes recebe o diagnostico em estágios avançados da doença, dificultando a possibilidade de tratamento curativo.
Development Model on Prevention of Land and Forest Fire in the Peat Land Area with Empowerment Society Approach (Case Study in West Kalimantan)
Authors: Maswadi  , Oktoriana Shenny , Hazriani Rini , Maulidi
Published: January 2021

Land fires are an annual agenda in Indonesia, especially in areas covered by peatlands. Peatland management using fire is the main cause. The general paradigm for land fires is that the farmers' economy is low. In fact, the factors that cause land fires are not only from the economic aspect, but from the social and institutional aspects which affect the behavior of farmers. Therefore, the purpose of this study is (1) to analyze the correlation of factors that influence land burning behavior, and (2) to determine the model for the changing of burning behavior into non burning farm land cultivation, in order to prevent land fire in Kuburaya Disrict and Bengkayang District, West Kalimantan. The research involved farmers farming on peatlands in both districts. Regression models was used for the correlation analysis. Based on the results of the regression analysis, a land burning behavior change model was determined based on the influencing factors descriptively. The result of the analysis showed the factors that significantly influence land burning behavior at the household level are knowledge level (consist of farming problems faced by farmers, agricultural extension materials and the application of technology), observance of rules, activeness of mutual assistance, cosmopolitan level, appraisal on burning behavior, and imitation level. The resulting model for changing the behavior of burning land is implementing activity of assistance, social capital stimulus and positive agreements/ pressure to the land users.

Published: January 2021

Background: To optimize screening abbreviated breast MRI (ABMR) operations, patient throughput times of ABMR were compared to breast ultrasound (US) and full protocol breast MRI (FPMR).Methods: Patient throughput times (mean ± standard error) and its subcomponents were analyzed for 95 ABMRs, 90 breast US exams, and 50 FPMRs. Total patient throughput was measured from registration time to the time of the last acquired image. Actual exam time was time difference between the first and last acquired images and pre-examination time was the calculated difference between throughput and actual exam times. Results: ABMR total patient throughput time was shorter than FPMR (55.7 ± 1.7 vs. 63.1 ± 2.0 min; difference, 7.4 min, 13%; p<0.001), but longer than breast US (39.1 ± 1.3 min; difference, 16.6 min, 30%; p<0.001). ABMR had shorter actual scan times than FPMR (13.4 ± 0.14 vs. 18.6 ± 0.25 min; p<0.001), but longer than US (9.6 ± 0.46 minutes; p<0.001). There was no difference in the pre-examination times between ABMR and FPMR (42.3 ± 1.7 vs. 44.6 ± 1.9 min; p = 0.357); pre-examination times were longer for both MR exam types compared to US (29.5 ± 1.3 minutes; p<0.001). Conclusion: ABMR patient throughput times are faster than FPMR, but these gains are limited as they have no impact on pre-examination activities which comprise the lengthiest components of the patient flow process. US patient flow currently remains faster than ABMR; however, comparable ABMR times could be achieved by further omitting certain sequences and optimizing pre-examination processes.
The Association of Neoadjuvant Systemic Treatment on Hormone Receptor and Her2 Expression in Breast Cancer
Authors: MacFaul William , D Hughesa T Michael , Hitosd Kerry , Pathmanathane Nirmala , Nguia Nicholas K
Published: January 2021

Background:  Pathological complete response (pCR) following neoadjuvant systemic treatment(NAST) for breast cancer is associated with improved prognosis; however, a large proportion of patients have residual disease. Oestrogen Receptor (ER) and HER2 status have been shown to affect likelihood of achieving pCR, with ER positive tumors being more treatment resistant. As hormone receptor status is heterogeneous within tumors, we postulated that, following NAST, ER expression would change in patients with residual disease, as the ER negative cells within the tumor are more treatment sensitive. Methods: A retrospective case series of patients treated with NAST prior to surgery at our institution was conducted. Information collected included demographic data, tumor grade, hormone receptor and HER2 status both before and after treatment, and pCR rates.Results: Of the 44 patients included, half achieved pCR. HER2 status (P=0.01), and subtype (P=0.008) were significantly associated with pCR. HER2 positive/ER negative tumors were most likely to undergo pCR. Approximately 80% of residual disease was ER positive. Higher levels of ER expression were also associated with increasing residual cancer burden (RCB) class (P=0.037). There was no trend between change in ER or HER2 expression following NAST. Median change in ER expression was 80% to 90% (P= 0.89), HER2 intensity changed from 3.0 to 2.2 (P=0.67) following treatment. Conclusion: Consistent with the literature, we have shown associations between ER and HER2 status and PCR, and between ER expression and residual disease burden. Our study was not able to demonstrate a significant trend in hormone and HER2 expression.

A set of m distinct nonzero rationals {a1,a2,…,am} such that aiaj+1 is a perfect square for all 1 ≤ i < j ≤ m, is called a rational Diophantine m-tuple. It is proved recently that there are infinitely many rational Diophantine sextuples. In this paper, we construct infinite families of rational Diophantine sextuples with special structure, namely the sextuples containing quadruples and quintuples of certain type.
L∞ - derivations and the argument shift method for deformation quantization algebras
Authors: Sharygin Georgy
Published: January 2021

The argument shift method is a well-known method for generating commutative families of functions in Poisson algebras from central elements and a vector field, verifying a special condition with respect to the Poisson bracket. In this notice we give an analogous construction, which gives one a way to create commutative subalgebras of a deformed algebra from its center (which is as it is well known describable in the terms of the center of the Poisson algebra) and an L∞-differentiation of the algebra of Hochschild cochains, verifying some additional conditions with respect to the Poisson structure.

Published: January 2021

Let G be a graph with edge set E(G) that admits a perfect matching M. A forcing set of M is a subset of M contained in no other perfect matchings of G. A complete forcing set of G, recently introduced by Xu et al. [Complete forcing numbers of catacondensed hexagonal systems, J. Combin. Optim. 29(4) (2015) 803-814], is a subset of E(G) on which the restriction of any perfect matching M is a forcing set of M. The minimum possible cardinality of complete forcing sets of G is the complete forcing number of G. In this article, we discuss the complete forcing number of rectangular polyominoes (or grids), i.e., the Cartesian product of two paths of various lengths, and show explicit formulae for the complete forcing numbers of rectangular polyominoes in terms of the lengths.

Climate change has resulted in rising sea levels that could lead to floods in coastal areas. This has an impact on the people living in the area. Factors affecting the vulnerability of communities in the face of disasters include poverty, education level, knowledge, awareness, and availability of easily accessible information. Poor socially vulnerable societies and living in coastal areas make it even more vulnerable to frequent robust flood threats. For that the poor must have knowledge and preparedness in the face of rob flood in its territory. This research is a qualitative research with case study approach aimed at analyzing the knowledge of the poor about rob flood and poor people's preparedness in the face of rob flood. The research location is located in Kecamatan Penjaringan, North Jakarta with the participants selected through purposive sampling technique. Techniques of collecting data using interviews, observations, and study documents that are then analyzed thematically according to the code that has been determined. The results show that poor people's knowledge about rob floods is still low as their knowledge has not yet led to the safety (safe culture) habit of dealing with robot floods, their knowledge is based solely on experience during their stay in areas affected by rob floods and often experience them, as well as poor people's preparedness in the face of floods, rob is still low, the poor have not been empowered or involved in programs or activities related to disaster preparedness. The poor need to improve their knowledge capacity through education, training, socialization, and simulations that can be done alone or with government support.
Managing Marine Environmental Pollution using Artificial Intelligence
Authors: Agarwala NItin
Published: January 2021

The marine environment has deteriorated to an extent that it has begun to impact human health and the planet itself.  The primary cause of this deterioration as identified are, an increasing population, the industrial revolution and the increased use of fossil fuels.  While the damage done to the environment cannot be undone, the impact can be lessened by better understanding the ocean and monitoring future pollution using technology.  Such an effort will help achieve sustainability as laid out by the Sustainable Development Goals 2030 of the United Nations.  The article aims to provide an insight into one such technology, namely ‘Artificial Intelligence (AI)’, being developed to understand and monitor the marine pollution.  In doing so the article will discuss the emerging opportunities and risks associated with the use of AI in managing marine environmental pollution through sustainability.  To strengthen the argument, use-cases of AI in the marine environment and their scalability are discussed.
Fan-ning the flame
Authors: Dove-Viebahn Aviva
Published: January 2021

While promoting recent seasons of supernatural Western horror series Wynonna Earp (2016), cable channel Syfy released several fan-style videos championing the show’s resident lesbian couple: the protagonist’s sister, Waverly, and police officer Nicole Haught (celebrated via the portmanteau “WayHaught”). In 2019, a network “shipping” its own queer characters in service of fans contrasts starkly with the televisual landscape twenty, or even ten, years prior, when viewers invested in lesbian characters and/or same-sex couples relied on subtext and fan paratexts to fuel their enthusiasm for mostly unacknowledged or thwarted relationships between female characters. In this article, I engage in a two-part interrogation of the representation of lesbian romance on cult television shows in the last twenty-five years, with a focus on Wynonna Earp and its historical antecedents—supernatural, sci-fi, and fantasy shows featuring women and their female companion(s) (whether close friends or lovers). This includes a historiography of the development of lesbian fan communities around certain shows from the late 1990s and early 2000s, as well as an analysis of the narrative stakes and character development in both historical and contemporary shows, like Earp, in order to interrogate their representations of subtext or main text romantic pairings.

Dalam penelitian ini, zona target berada pada Formasi Talang Akar yang secara petroleum system diketahui sebagai source rock dan reservoar. Untuk mengetahui kandungan fluida hidrokarbon yang terkandung dalam reservoar tersebut, maka dilakukan prediksi fluida dengan menggunakan metode Amplitude Versus Offset (AVO). Data yang digunakan dalam penelitian ini terdiri atas data 3D pre-stack time migration dan 2 data sumur (CHA-1 dan CHA-2) dengan kedalaman 1226-1300 ms pada sumur CHA-1 dan 1262-1340 ms pada sumur CHA-2. Berdasarkan analisis AVO, dapat diketahui bahwa zona target penelitian termasuk ke dalam AVO kelas I yang diketahui sebagai high impedance contrast sand serta memiliki respon penurunan AVO seiring dengan bertambahnya offset. Sehingga, dapat diketahui bahwa reservoar pada zona target tidak terindikasikan keberadaan gas, melainkan terindikasi sebagai zona wet sand yang mengandung fluida berupa minyak. Hasil tersebut juga didukung dengan nilai saturasi air sebesar 48.27% pada sumur CHA-1, sedangkan pada sumur CHA-2 sebesar 36.85%.
