Published: July 2020

Aim of the study is to implement Geomatics learning innovations by applying the scaffolding Problem-Based Learning integrated model to improve the student’s Vocational HOTS. The method applied was qualitative with the participation of 2 groups of students practicing consisting of 4 people each. The level of cognitive mastery was measured with the Bloom taxonomy (C1-C6). The results of the investigation showed that the integrated model effectively formed students’ Vocational HOT Skill as a group in 3 stages. The first stage of learning focused on mastering the operation of equipment needed in practice (C2-C3 and partly C4). In the second stage, the students have mastered most of the cognitive analysis and accuracy of practical data (C4-C5) and in the third stage, they made practiced steps more effectively and successfully correlated to the Indonesian National Standards (SNI) level (C6) at the moderately accurate. The application of the Scaffolding Problem-Based Learning model has a positive impact that students get21st-century learning with the main characteristics (4C), consisting: Communication, Collaboration, (Critical thinking, and problem-solving), and Creative thinking. Learning outcomes enriched with higher-order thinking skills can be seen when students take advanced Geomatics material, They already work with groups to map the area more independently
Victim, Victor, or Villain? The Unfinalizability of Delilah
Authors: Lackowski Mark
Published: July 2020

Delilah is one of the more enigmatic characters in the Hebrew Scriptures. She is marked by a series of ambiguities in the text that pose a host of unanswered questions. Is she a Philistine, an Israelite, or something else? What exactly does her name mean and what is the nature of her relationship to Samson? And why does she help the Philistines capture Israel’s notorious strongman? Despite all this ambiguity, much of her reception history is rigidly consistent. The dominant trend is the portrayal of Delilah as the reviled seductress who bedevils Samson. This interpretation was also promulgated among ancient readers of the story such as Josephus and Pseudo-Philo, who identify Delilah not only as a prostitute and a Philistine, but as the wife of Samson. These types of interpretive gap-filling serve as early exemplars of a long and nearly unwavering reception history in which Delilah is unequivocally the villain. If there is any other interpretive potential lying dormant in the text, then it is rarely actualized. Building upon the work of contemporary feminist and womanist scholars, I intend to subvert that trend by arguing that Delilah can and should be read in a variety ways due to the intentional ambiguity employed by the biblical author. Furthermore, by drawing upon the work of Mikhail Bakhtin, I will identify the “unfinalizability” of Delilah’s character and demonstrate how she simultaneously embodies the role of victim, victor, and villain.

Objectives

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21-OHD) is a common autosomal recessive disorder caused by defects in the CYP21A2 gene. We aimed to determine the prevalence of the most commonly reported mutations among 21-OHD Egyptian patients and correlate genotype with phenotype.

Methods

Molecular analysis of the CYP21A2 gene was performed for the detection of the six most common point mutations (p.P30L, p.I172N, p.V281L, p.Q318X, the splice site mutation Int2 [IVS2–13A/C>G], and the cluster of three mutations [p.I236N, p.V237E, and p.M239K] designed as CL6). Polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) method was performed on 47 unrelated Egyptian 21α-OH deficiency patients and their available parents to detect the presence of the six most common point mutations.

Results

Screening for the six most common point mutations in CYP21A2 gene, revealed mutations in 87.2% (82/94) of the studied alleles corresponding to 47 Egyptian patients. The most common mutation among the studied cases was IVS2-13C/A>G that was found to be presented in a frequency of 46.8% (44/94). The genotype/phenotype correlations related to null, A, and B groups were with PPV of 100, 55.5, and 83.3%, respectively.

Conclusions

The described method diagnosed CAH in 80.8% of the studied patients. Good correlation between genotype and phenotype in salt wasting and simple virilizing forms is determined, whereas little concordance is seen in nonclassical one. Furthermore, studying the carrier frequency of 21-OHD among the normal population is of great importance.
Antenatal survey of women’s birthing choices in Qatar
Authors: Mohan Suruchi , Ghani Rauf , Lindow Stephen , Farrell Tom
Published: July 2020

Objectives

Attitudes towards labour care and women’s choices for their preferred mode of delivery are documented in studies from the around the world, however less is known about women’s birth choices in the Middle East. This study was designed with the aim of exploring beliefs and attitudes in this region.

Methods

Voluntary participation in an ethics-approved survey was offered to pregnant women attending the antenatal clinic at Sidra Medicine from August 2018 to January 2019 with no exclusion criteria.

Results

Of the 346 respondents, 58.1% were Arabic and the remainder expatriates. This group composition allowed comparison between women native and non-native to the Gulf region. Arabic and non-Arabic women differed significantly in previous birth experiences: the Arabs had had more doctor-led deliveries (45 vs. 34%), epidurals (56.6 vs. 45%) and episiotomies (65.7 vs. 54%). 70.2% of the respondents chose a normal delivery as their preferred birth mode though a smaller majority of the Arabic subgroup did (63.2 %). 60.4% preferred delivery by doctors and longer hospital stays (47.6), more so Arabic participants (64.7 and 68.6 %). Significantly less Arabs, would choose husbands as birth partners (51.2 vs. 86.2%) and more expressed a gender preference for doctors. Other group choices are presented.

Conclusions

Though women in this region made comparable choices about mode of delivery as their Western counterparts, they demonstrated an expectation of a culturally distinct and more medicalized approach to care in labour. The findings highlight the need for further studies to inform regional obstetric care and health education interventions as well as tailoring maternity care services.
Cow Vigilantism and India’s Evolving Human Rights Framework
Authors: Pratap Ravindra
Published: July 2020

The paper seeks to understand India’s evolving rights framework in the backdrop of cow vigilantism. To that end it discusses the human right to food and nutrition, international discussion on minority rights issues in India and the relevant legal and constitutional discussion in India. It finds that India’s rights framework has evolved since proclamation of India as a Republic in 1950 based on the supremacy of its written constitution containing fundamental rights and directive principles of state policy interpreted finally by its Supreme Court. The government took a wise step by not challenging a judicial rebalancing of the rights framework in response to certain executive measures and the Supreme Court interpreted the right to life to include not only the right to the choice of food but also the right to privacy and thereby underscored the obligation of the State to compensate the victims of cow vigilante violence. However, a constitutional polity and secular state would do all well if it did any further necessary to better guard against any recurrence of the breach of civil peace, much less violence, on purely secular issues, including by strengthening and increasing dialogue with all representative communities in all its decision-making on such matters.

Published: July 2020

Two-dimensional (2D) layers of transition metal carbides, nitrides, or carbonitrides, collectively referred to as MXenes, are considered as the new family of 2D materials for the development of functional building blocks for optoelectronic and photonic device applications. Their advantages are based on their unique and tunable electronic and optical properties, which depend on the modulation of transition metal elements or surface functional groups. In this paper, we have presented a comprehensive review of MXenes to suggest an insightful perspective on future nanophotonic and optoelectronic device applications based on advanced synthesis processes and theoretically predicted or experimentally verified material properties. Recently developed optoelectronic and photonic devices, such as photodetectors, solar cells, fiber lasers, and light-emitting diodes are summarized in this review. Wide-spectrum photodetection with high photoresponsivity, high-yield solar cells, and effective saturable absorption were achieved by exploiting different MXenes. Further, the great potential of MXenes as an electrode material is predicted with a controllable work function in a wide range (1.6–8 eV) and high conductivity (~104 S/cm), and their potential as active channel material by generating a tunable energy bandgap is likewise shown. MXene can provide new functional building blocks for future generation nanophotonic device applications.

PLAY ME: interactive sonification of sexual arousal in long-distance relationships
Authors: Arnold Rudolf
Published: July 2020

Music is the best medium for expressing emotions and arousal nonverbally. PLAY ME is a gender-neutral Arduino-based system that allows partners in a long-distance relationship to perceive each other’s sexual arousal and to provide stimulation of erogenous zones using music. PLAY ME’s main parts are a tiny pneumatic anal probe connected to a pressure sensor and a bodysuit with integrated vibrators. Whenever both partners wear these devices, a real-time exchange of emotions and corporeal feelings can be enabled. Three sensors capture genital sexual arousal and transform it into music: a pulse sensor, a sensor for galvanic skin response and a pneumatic anal pressure probe. The anal probe measures pelvic tensions and contractions. Its signal controls the main voice. Higher arousal leads to stronger pelvic muscle tensions. Measured data are mapped to pitch, so the level of sexual arousal is audible in a comprehensive way, and orgasms can be clearly identified by regular pulsating sounds. The pulse sensor and the skin response sensor are the driving rhythm and drone frequency. The vibrators in the bodysuit are controlled by sound that is generated by the partner using any audio source. Mixing the sounds generated by the sensors and the instrument leads to interactive music that can enhance erotic feelings and sexual arousal in the way of biofeedback. This article describes the background and construction of the PLAY ME system and shows diagrams of sensor values recorded during sexual stimulation. After a discussion of the results, there is an outlook toward further development.

Published: July 2020

In the present work the composition of biogenic volatile organic compounds (BVOCs) and the essential oil (EO) of Helichrysum araxinum Takht. ex Kirp. aerial parts, together with the antimicrobial activity, were investigated. The results showed the prevalence of sesquiterpene hydrocarbons in both spontaneous emissions as well as in the EO. The main compounds of BVOCs were γ-curcumene (10.7%), γ-muurolene (9.2%), and β-selinene (8.5%). This latter constituent also showed a similar amount in the EO and represented the most abundant compounds together with α-selinene (8.0%). It is Interesting to note the same percentage of monoterpene hydrocarbons (MHs) in both the aroma profile and the EO (18.0%) with the same most abundant compounds: β-pinene (6.3% in BVOCs vs. 5.1% in EO, respectively) and limonene (4.5% in VOCs vs. 4.9% in EO, respectively). With regard to the antimycotic activity, the EO showed to be inactive against the tested strains, while a moderate antibacterial activity was shown against Staphylococcus isolates.

Published: July 2020

La pirazinamida es un profármaco utilizado en infecciones contra Mycobacterium tuberculosis y su resistencia se debe principalmente a mutaciones en el gen pncA. En este estudio se realizó la detección de mutaciones puntuales de este gen, en aislamientos clínicos del estado de Nuevo León. Se elaboraron modelos tridimensionales de la enzima pirazinamidasa por secuenciación y mediante el uso de herramientas computacionales. Se observó la presencia de mutaciones importantes en ocho muestras, en dos de ellas se presentaron codones de terminación. Las predicciones realizadas mostraron que las mutaciones Q10P Y W68S afectan estructuralmente al sitio activo. Las mutaciones P62L y D63A se presentan en un sitio importante; sin embargo, la enzima permanece estable. Por el contrario, cuando se analiza la mutación S179R se encuentra que la función enzimática es altamente inestable.
Test-Retest Reliability and Minimal Detectable Change of the Instrumented Modified Clinical Test of Sensory Interaction on Balance in Healthy, Older Adults
Authors: Watson Seth , Trudelle-Jackson Elaine
Published: July 2020

Background and Purpose:

Test-retest reliability has not been previously reported for the instrumented modified Clinical Test of Sensory Interaction on Balance (i-mCTSIB) utilizing the Neurocom Very Simple Rehab (VSR) Sport force plate. The VSR Sport is a portable, relatively inexpensive force plate system utilized to assess postural stability in various populations. Therefore, the purpose of this study is to determine the test-retest reliability, standard error of measurement (SEM), and minimal detectable change (MDC) of the i-mCTSIB when assessed using the VSR Sport in a sample of healthy, older adults.

Methods:

This was a methodological study with 20 healthy, older adults between the ages of 65 and 85 years. Participants were tested twice in a single session on the i-mCTSIB utilizing the VSR Sport force plate. The mean sway velocity (°/s) measurements for the 2 trials were compared for each test condition to compute intraclass correlation coefficients (ICCs) for each measurement. Standard error of measurements and minimal detectable change at the 90% confidence level (MDC90) were also calculated.

Results and Discussion:

The test-retest reliability for each of the test conditions ranged from 0.762 to 0.909, which can be broadly interpreted as good-to-excellent reliability. The ICC(2,k) value of 0.898 for the composite score can also be interpreted as excellent reliability. Our results revealed small SEM for all test conditions (SEM = 0.060-0.101) except for the foam surface, eyes closed condition, with an SEM of 0.481. The MDC90 results for all testing conditions ranged from 0.140 to 0.285 except for the foam surface, eyes closed condition, which had an MDC90 = 1.12.

Conclusions:

The i-mCTSIB measurements utilizing the VSR Sport demonstrated good-to-excellent test-retest reliability. The clinical relevance of this study is that it demonstrates that the VSR Sport is a feasible alternative to other more expensive computerized systems used for the assessment of postural sway. MDC90 scores allow interpretation of change in i-mCTSIB scores following intervention. Practice effects may have contributed to the larger MDC90 for sway scores in the foam surface, eyes closed condition.

Authors: Duggan John David , Moody Jeremy , Byrne Paul J. , Ryan Lisa
Published: July 2020

Camogie (kuh·mow·gee) is a traditional, amateur Gaelic sport played by female athletes. This invasion-based field sport involves high-intensity intermittent physical demands. There is currently a dearth of available research in intercounty despite the prevalence of research in the male version of the game (hurling). The aims of this article are to provide strength and conditioning recommendations for the sport of camogie, specifically at intercounty level. These recommendations include considerations working with intercounty female camogie athletes, specific camogie injury epidemiology, physiological demands, and practical strength and conditioning for implementation by practitioners. Moreover, a sport-specific testing battery; development of physical attributes to enhance match-play performance; a proposed annual periodization cycle; and sample strength, speed and agility programs will be discussed.
Towards a World History of the Medieval Gulf
Authors: Fromherz Allen
Published: July 2020

The Gulf region during the “Middle Period,” from around 1000 - 1500 CE, faced what seemed to be two insurmountable challenges: the fall of the ‘Abbasids in Baghdad in 1258 CE as well as increased competition from the Red Sea. Despite these two threats to the prosperity of trade in the region, however, Gulf ports remained vibrant and important centers of trade and cosmopolitanism. The Gulf, with its merchant economy and its relatively tolerant port cities, did not march in lockstep with the fate and fortunes of metropolitan cities such as Baghdad. Instead of William McNeill’s webs of history with their orbiting points, medieval Gulf ports were spiders spinning silk in the wind, attaching to whatever space along the shore was most convenient. Gulf port polities were diffuse, detached from imperial centers and, for dogmatists, sometimes dangerous, as they do not fit usual religious paradigms. Marshall Hodgson rightly identified the Middle Period as the crucial period for the Islamicate world. The centuries between 1000–1500 CE were characterized by a remarkable unity that existed across the Medieval Islamic world despite political divisions. However, there was far more to the story of medieval Gulf culture, and possibly the whole medieval Middle East, than Hodgson’s narrative of the consolidation of Islam, which focuses on trade, religious thought, and cultural influences setting out from agrarian, urban centers. The remarkable independence of Gulf ports from agrarian political power mixed with a heavy dependence on international trade fostered a distinctive cosmopolitan ethos directed beyond Hodgson’s Islamicate world.

Objective ― Analyzing gender-related specificities of hyperuricemia associations with lifestyle choices in the Russian Federation (RF) population. Material and Methods ― Cross-sectional survey was performed within the guidelines of the Russian national multicenter study ESSE-RF. The final sample size was 20781 people 25-64 years old. The effect of age, body mass index (BMI), diet, smoking status, and alcohol consumption on the incidence of hyperuricemia was evaluated. The analysis was carried out separately for men and women, using logistic regression. To build a model for predicting hyperuricemia, classification trees were used. Results ― Multidirectional associations of hyperuricemia were revealed both in women (with BMI, age, ‘Smart’ dietary pattern, alcohol consumption) and in men (with BMI, ‘smart’ dietary pattern, alcohol consumption, smoking status). The predictive accuracy of hyperuricemia incidence models was 60.4% in women vs. 65.7% in men. In both gender groups, BMI had the highest contribution to predicting the hyperuricemia incidence, while the next predictors, in terms of significance, differed among men and women. In women, the greatest impact, in decreasing order, was exerted by age, dietary patterns and drinking, whereas in men, by smoking status, dietary patterns and drinking. Conclusion ― In the RF population, there are multiple gender-specific associations of hyperuricemia with lifestyle choices, particularly nutrition, smoking and alcohol consumption.

Published: July 2020

Graves’ disease (GD), an organ-specific autoimmune disease, is the most common cause of hyperthyroidism. Tumour necrosis factor-alpha (TNF-α) exhibits immunological and metabolic activities involved in the induction and maintenance of immune responses. We attempted to evaluate the relationship between GD and serum TNF-α and its soluble receptors (sTNFRs), soluble TNF receptor 1 and 2 (sTNF-R1 and sTNF-R2). A total of 72 GD patients and 72 matched healthy individuals were recruited for this study. Serum TNF-α and sTNFRs were measured by sandwich ELISA. In our study, no significant difference was observed in TNF-α, but sTNFRs were found to be significantly elevated in GD patients compared to healthy individuals. Serum sTNFR levels were positively correlated with free triiodothyronine (FT3) and free thyroxine (FT4), and TNF-α was negatively correlated with thyroid-stimulating hormone (TSH) in the GD group. It was also shown that thyrotropin receptor antibody (TRAb) was positively correlated with TNF-α and sTNFRs. Spearman’s correlation analysis showed that only sTNF-R1 was positively correlated with complement C3. Multiple linear regression analysis suggests that serum levels of sTNF-R1 and FT4 may play an important role in the serum level of FT3. According to the median value of FT3 level, GD patients were further divided into a high FT3 group and a low FT3 group. The serum levels of sTNF-R1 in the high FT3 GD group were significantly higher than those in the low FT3 GD group. In conclusion, sTNFRs may play an important role in anti-inflammatory and immune response in GD.
Endothelial cells on the move: dynamics in vascular morphogenesis and disease
Authors: Fonseca Catarina G , Barbacena Pedro , Franco Claudio A
Published: July 2020

The vascular system is a hierarchically organized network of blood vessels that play crucial roles in embryogenesis, homeostasis and disease. Blood vessels are built by endothelial cells – the cells lining the interior of blood vessels – through a process named vascular morphogenesis. Endothelial cells react to different biomechanical signals in their environment by adjusting their behavior to: (1) invade, proliferate and fuse to form new vessels (angiogenesis); (2) remodel, regress and establish a hierarchy in the network (patterning); and (3) maintain network stability (quiescence). Each step involves the coordination of endothelial cell differentiation, proliferation, polarity, migration, rearrangements and shape changes to ensure network integrity and an efficient barrier between blood and tissues. In this review, we highlighted the relevance and the mechanisms involving endothelial cell migration during different steps of vascular morphogenesis. We further present evidence on how impaired endothelial cell dynamics can contribute to pathology.
Semiconductor whiskers for humidity sensors
Authors: Ostrovskii I. P. , Druzhinin A. O.
Published: July 2020

In present paper p-type GaPAs whiskers doped with Cu were obtained by VLS method in close bromine system. The whiskers have various morphologies and geometries: imperfect needle-like crystals, ribbons, perfect needle-like crystals and thin plates. The whiskers of various morphologies serve as thermoresistores with TCR of about 1-2 %. The whisker I-U characteristics were investigated dependent on their geometry and external conditions (humidity). Voltage arising on the thermoresisor for two polarities of current passing through it was shown to be dependent on air humidity. Miniature semiconductor sensors of humidity based on GaPAs whiskers have been designed. Physical principles of operation, the perculiarities of design, and main performances of the microsensors were discussed. The whiskers of small diameter (d=50 μm) were shown to measure humidity in the range j=35...97%   with sensitivity to humidity g =DU/Uj »2.5×10-3. The miniature dimensions of the whiskers provides very rapid response (of about a few sec) and small time of recovery (less than 30 sec).

In this paper, the technology of obtaining and effect of annealing on the morphology and optical properties of cadmium telluride thin films has been investigated. The effect of vacuum chamber modes on the growth of thin films has been studied. For obtained cadmium telluride thin films were used a modified thermal evaporation method deposited by Physical Vapor Deposition technique on a glass substrate with different thicknesses. The transmission measurements were carried with UV-ViS-NIR Spectrophotometer in the wavelength range 180-3300 nm, to analyze the optical properties as a function of wavelength. The optical band gap values were 1.49 eV for as-grown films and 1.46 eV after annealing. The refractive indexes of the samples were defined in the range of 2.6 – 2.8 for as-grown films and the indexes have increased after annealing depending on the wavelength region and film thickness. After annealing, the coalescence mode of growth is observed.

Heat Capacity of Decagonal and Icosahedral Quasicrystalline Phases at High Temperatures
Authors: Syrovatko Yu. V. , Levkovich O. O.
Published: July 2020

The paper deals with the calculations of heat capacity of quasicrystalline decagonal Al69Co21Ni10 and icosahedral Al63Cu25Fe12 quasicrystalline phases of Al–Co–Ni and Al–Cu–Fe alloys, respectively. According to the Gruneisen law, heat capacity is an energy characteristic, which reflects the phases’ resistance to failure. For calculations of the heat capacity, structure of quasicrystalline phases is considered in the model representation of anisotropic crystals. As a result, it is found that the heat capacity of quasicrystalline phases at high temperatures is the excessive one, i.e. it exceeds the Dulong-Petit value. Therefore, quasicrystalline phases at high temperatures are more stable, than the crystalline phase. For the decagonal quasicrystalline phase, heat capacity is more than 3R in the temperature range of ~480–1500 К, and for the icosahedral quasicrystalline phase – in the temperature range of ~380–1120 К. It follows that decagonal phases remain stable at high temperatures at which the icosahedral phases are destroyed.

Published: July 2020

Interaction between the components in the Ho-Fe-Sn ternary system was studied using X-ray diffractometry, metallography and electron microprobe analysis. Isothermal section of the phase diagram was constructed at 670 K over the whole concentration range. Component interaction in the Ho-Fe-Sn system at 670 K results in the existence of one ternary compound HoFe6Sn6 which crystallizes in the YCo6Ge6 structure type (space group P6/mmm, a=0.53797(2),   c= 0.44446(2) nm). The interstitial-type solid solution HoFexSn2 (up to 8 at.% Fe) based on the HoSn2 (ZrSi2-type structure) binary compound was found. Solubility of Sn in the HoFe2 binary (MgCu2 structure type) extends up to 5 at. %.

The Current Carriers’ Dispersion Law of a Crystal, Their Chemical Potential and a Set of Important Properties of Crystals
Authors: Budzhak Ya. S. , Wacławski T.
Published: July 2020

In this paper, a new non-parabolic dispersion law has been established, which for a small parameter of the spectrum nonparabolicity coincides with the known Kane’s nonparabolic dispersion law. The Kane’s dispersion law works well when the well-known parameter of nonparabolicity is much less than 1, and the new law works well enough when the parameter of nonparabolicity is less than 1. In addition, this law shows that crystals with a band gap (i.e., forbidden band width) Eg~10-1 eV – these are semiconductor crystals, crystals with Eg~10-2 eV – these are metals.
Ways to Improve the Efficiency of ТіО2-based Photocatalysts (Review)
Authors: Mironyuk I.F. , Soltys L.M. , Tatarchuk T.R. , Tsinurchyn V.I.
Published: July 2020

Water and air pollutants pose a significant environmental problem worldwide and photocatalysis is one way to address this global issue. Photocatalytic degradation of toxic substances under the influence of visible electromagnetic radiation is widely used for wastewater treatment. The most promising method of pollutant removal is the use of photocatalysts based on titanium (IV) oxide, which are recognized as one of the most effective due to chemical resistance, non-toxicity and low cost. However, their practical application is limited by the rapid recombination of photogenerated charge carriers and the selective absorption of light in the UV region due to the large width of band gap. To solve this scientific and practical problem, it is necessary to modify the surface, for example, through metallic or nonmetallic doping, in order to increase its photocatalytic activity due to additional absorption in the visible range of the spectrum. This review presents an analysis of current research on ways to increase the efficiency of TiO2-based photocatalysts.
Some remarks on the study of the Cultural History of Western Esotericism in Latin America

Published: July 2020

A comienzos de 1990, el esoterismo occidental emergió como objeto académico dentro de la Historia. Desde inicios del siglo XXI, gracias a un gran caudal de investigación, nuestro campo se desarrolló en dos aspectos: surgieron revistas especializadas y tres grandes redes de especialistas (la Association for the Study of Esotericism-ASE; el European Society for the Study of Western Esotericism-ESSWE; y, nuestro Centro de Estudios sobre el Esoterismo Occidental/UNASUR). Aunque la historia del esoterismo occidental en América Latina aún no se ha escrito, nos parece pertinente señalar algunas prevenciones metodológicas en el ámbito de este campo académico.

Cosmopolitismo y migraciones
Authors: Morales Benítez Antonio
Published: July 2020

Algunos hombres de la masonería campogibraltareña estrecharon vínculos con América. Este cosmopolitismo se produjo en los dos sentidos. Uno de los promotores de la expansión masónica, que estaría en la base del desarrollo posterior, había conocido la Orden en La Habana.  El fundador y venerable maestro de la primera logia del siglo XX en el Campo se instalaría posteriormente en la ciudad norteamericana de Tampa. Hubo un flujo continuo con la emigración de otros masones campo gibraltareños a ciudades como Nueva York. Asimismo, tras la guerra civil el continente americano fue un lugar de exilio para algunos de ellos.
El mito del complot antipatriótico y la Asociación Masónica Internacional (España, 1921-1975)
Authors: Domínguez Arribas Javier
Published: July 2020

Este artículo estudia un leitmotiv de la propaganda antimasónica española: el que acusaba a la Asociación Masónica Internacional (AMI) de ser responsable de una conspiración antipatriótica. Tras presentar los orígenes del mito complotista y la realidad de la verdadera AMI, se realiza un recorrido cronológico por la utilización del tema en la prensa y la literatura de propaganda durante las décadas centrales del siglo XX (1921-1975). Asimismo, se presta una especial atención al rol que desempeñó el propio Francisco Franco en la estigmatización de la AMI.
Rafael Gerona Martínez: “el padre de todos”
Authors: Según-Alonso Manuel
Published: July 2020

El masón madrileño Rafael Gerona Martínez utiliza su pertenencia a la masonería y sus contactos políticos para salvar a multitud de personas consideradas quintacolumnistas en Madrid cuando el gobierno republicano había perdido el control de las calles. Para ello, junto al peruano Antonio Ibáñez Gutiérrez y bajo esa bandera, creó un asilo en el que recibieron refugio unas quinientas personas de derechas y que, gracias a ello, ninguna de ellas perdió la vida. Este trabajo, pretende sacar del olvido a Rafael Gerona que arriesgó su vida en un gesto de fraternidad y altruismo que nunca le fue reconocido.
Mujeres y redes masónicas intergeneracionales en México
Authors: García Robles Marco Antonio
Published: July 2020

A lo largo del siglo XIX hubo personajes que ostentaron el poder político en México y cuya influencia alcanzó a las élites regionales, mediante sus posiciones en las logias de diferentes ritos, pero también gracias a las redes familiares construidas en torno a mujeres destacadas en el ámbito social. Así pues, en el presente texto se explora una lectura de la historia desde el género y se evidencia la existencia de genealogías vinculadas a las masonerías.
Prácticas docentes y desarrollo de conducta prosocial en alumnos de primer ciclo básico de una escuela chilena
Authors: González Navarro María-Gracia , Navarro Saldaña Gracia
Published: July 2020

Se identifican las prácticas docentes de profesores de un establecimiento educacional chileno, con alto índice de vulnerabilidad social (90.5%), y su relación con la aparición de conductas prosociales. Se analizó una muestra de siete profesores jefes del primer ciclo básico, a través de entrevista y observación directa. Los resultados muestran que el Comportamiento Normativo de los profesores tiene impacto en la aparición de conductas prosociales en los alumnos y que éstas se ven obstruidas por la inconsistencia en las normas y por el énfasis en la figura de autoridad para su cumplimiento. Las prácticas docentes no están promoviendo el desarrollo moral de los alumnos y, por lo tanto, no facilitan la aparición de conductas prosociales, las cuales funcionan como factor protector ante la conducta violenta.

Así, la figura del profesor es fundamental para el desarrollo de conductas prosociales, siendo efectivas en cuanto generan o no oportunidades para el desarrollo de la moralidad.
Subjetivación y Dispositivo: una propuesta de análisis para sujetos en condiciones de pobreza
Authors: Ghisiglieri Francisco
Published: July 2020

Con este artículo se aspira a generar una caja de herramientas que permita abordar los procesos de subjetivación en condiciones de pobreza. Para ello, se trabajan las nociones de procesos de subjetivación, dispositivo y pobreza, debido a sus capacidades de incluir en el análisis del sujeto las dimensiones ligadas al poder y al entramado discursivo-social. Se definen como virtudes de este enfoque: analizar las prácticas en su positividad; definir sistemas conservando su carácter acontecimental y singular; aproximarse a un abordaje de la subjetivación en su multiplicidad; y por último, aportar en la búsqueda de mayores dominios de libertad sobre nuestra vida y sus condiciones.
Sexual life assessment in individuals with different kind of relationships

Published: July 2020

Sexual life and intimacy mainly is based by one’s personality, knowledge and attitudes toward others. Someone’s personality can tell us how they approach all sorts of different things in life, including sexual life. To audit sexual life it is necessary to assess it through asking people who have a regular partner or whoever they are having sex, or their last relationship. The study included 500 subjects from Albania and Kosovo. The questionnaire was delivered through Survey planet app. The audit was opened during June 2019. Questionnaire contains 15 questions with A, B, C alternatives. The data were analyzed through SPSS software. Using the program, a series of Student’s t-tests was conducted for independent samples and correlation analysis with Pearson’s coefficient. The answers were categorized in three categories: mostly A, mostly B and mostly C. Female respondents were 54.6 % whereas 45.4% male. The majority, 78% ranked in age group 21-50 years old, from whom 71.4 % were married. Mostly A score frequently found at 53.60 % of participants which sounds like they and their partners have a really healthy and satisfying sex life.  “Mostly B” answered by 32% of participants which means that they were mostly satisfied with their sex life, and it seems like sometimes they can feel a little disconnected. Mostly C score is most commonly found at 14.40% of participants. This study shows that more than a half of the participants have a satisfying and a healthy sexual life.
"Calagurris Iulia". Ciudad y territorio en los procesos de monumentalización de época altoimperial
Authors: Calonge-Miranda Adrián
Published: July 2020

Con Augusto, Calagurris Iulia (Calahorra, La Rioja) alcanzó el rango de municipium de derecho latino. Esta promoción jurídica trajo consigo el inicio de la monumentalización de la ciudad y la construcción de las primeras edificaciones de carácter público. Este proceso continuó con el gobierno de los Flavios y los Antoninos. Pero no solo el enclave urbano fue transformado, sino también su entorno rural cuyo mayor exponente fue la centuriatio. Las villae se vieron influenciadas por cada uno de los procesos de monumentalización detectados en la ciudad y que vinieron a coincidir con etapas de dinamismo.
Tomando como ejemplo Calahorra y usando los datos aportados por las fuentes escritas, la epigrafía y, especialmente, la arqueología; se va a analizar cómo, en estos periodos de bonanza económica, se desarrollaron las edificaciones de carácter público de la ciudad, su urbanismo y su territorio jurídicamente adscrito.
INVESTIGATION OF VARIABLE MODES OF CENTRALIZED HEAT SUPPLY SYSTEMS OPERATION WITH QUALITATIVE AND QUANTITATIVE REGULATION
Authors: Rafalskaya T. A , Mansurov A. R , Mansurova A. R
Published: July 2020

The combined method of generating electric and heat energy at CHP plants has been and remains the most effective way of fuel saving both in housing and communal services and in industry. In Russia, historically, a qualitative method of regulation has been adopted, which consists in changing the temperature of the fluid depending on the change in the temperature of the outside air at a constant flow rate of the fluid. An analysis of the heat supply schemes of a number of Russian cities revealed that central quality regulation at heat sources has practically ceased everywhere. In modern methods of calculating the qualitative and quantitative regulation, the main load is heating, and the load of hot water is taken into account only by increasing the flow rate of network water and the variable modes of joint operation of heating and hot water systems are not calculated. Thus, at present, there are no methods for calculating the qualitative and quantitative regulation, allowing to fully taking into account the effect of the load of hot water on the operation of heating systems. Therefore, in modern conditions, the previously developed methods and technological methods of controlling the combined heat load are characterized by a decrease in efficiency, and, accordingly, the problem of their optimization arises. For different temperatures of outdoor air, the calculation of variable operating modes of the heat supply system was carried out, which showed that the existing schedules of qualitative and quantitative regulation cannot provide a comfortable temperature condition of the premises. Under the conditions of a connected supply of heat, simply adding up the flows of network water for heating and hot water supply fails to achieve optimal thermal conditions for the premises. Therefore, further improvement of the technology of the central qualitative and quantitative regulation of the heat load taking into account hot water supply is required.
APPLICATION OF ANTHRACITE FLOTATION ENRICHMENT WASTE IN PRODUCTION OF POROUS AGGREGATE BASED ON LIQUID-GLASS COMPOSITIONS
Authors: Abdrakhimov V. Z
Published: July 2020

Reduction of reserves of traditional natural raw materials for production of porous aggregates forces to look for new ways of its replacement by various types of technogenic raw materials. At the same time, the experience of advanced Western foreign countries has shown the practical, economic, environmental and technical feasibility of this direction and application as a tool for protecting the natural environment from pollution. In the present work it is shown that the most appropriate use wastes fuel and energy complex in the manufacture of insulating materials, such as porous aggregates with heat conductivity not more than 0.25 W/m•operating system. Waste from anthracite flotation enrichment was used as a thinning agent and burnout additive. Waste flotation enrichment of anthracites have an increased content of PP (loss during calcination = 42.4 %) and carbon content (C = 13.84 %), so they were used for the production of porous aggregate not only as a thinner, but also as burnout additives. Developed on the basis of waste flotation enrichment of anthracites and beet compositions for porous aggregates, which have high rates of compressive strength and softening factor, and the mark on the bulk density does not exceed M400. Studies have shown that the porosity on the exterior of the product, in contrast to the internal almost no form, ie waste flotation enrichment of anthracites contributes to the porous filler closed pores. The presence of pores of isometric shape and oval closed porosity in the porous filler gives it mechanical strength, and slit-like pores have a harmful effect. Innovative proposals for obtaining a porous aggregate have been developed. A patent of the Russian Federation was obtained for the obtained method of producing a porous filler based on a liquid-glass composition.
The role of the cardiac lymphatic system in the development and progression of heart failure and novel therapeutic approaches for its management in post-infarction cardiac remodeling
Authors: Korneva Yu. S. , Ukrainets R. V.
Published: July 2020

Cardiac lymphatic vessels play a vital role in maintaining homeostasis in both physiological and pathological conditions, providing outflow of metabolites. It has been shown that myocardial infarction and postinfarction cardiac remodeling is accompanied by the lymphatic remodeling, which entails functional disorders and is of great importance in heart failure pathogenesis. As a result of progressive myocardial edema, hypoxia and fibrosis of the interstitial space increase, aggravating edema. Other pathways of additional myocardial damage and contractility reduction are triggered. Lymphatic efflux is associated with arrhythmias. Experimental models showed the positive effect of exogenous activation of lymphangiogenesis in relation to the prevention and treatment of heart failure, which can be further used to improve treatment regimens. This review discusses cardiac lymphatic remodeling after myocardial infarction, as well as the pathogenesis of related complications.
